1Appropriate treatment strategies improve survival of hepatocellular carcinoma patients with portal vein tumor thrombus显示文摘AIM:To evaluate the survival benefits of different treatment strategies for hepatocellular carcinoma(HCC)patients with portal vein tumor thrombus(PVTT)and to determine the prognosis factors.METHODS:Between 2007 and 2009,338 HCC patients treated for PVTT were retrospectively studied.The patients were divided into 4 groups that underwent different treatments:the conservative treatment group(n=75),the transarterial chemoembolization(TACE)group(n=86),the hepatic resection group(n=90),and the hepatic resection associated with postoperative TACE group(n=87).Survival rates were determined using the Kaplan-Meier method and differences between the groups were identified through log-rankanalysis.Cox’s proportional hazard model was used to identify the risk factors for survival.RESULTS:The mean survival periods for patients in the conservative treatment,TACE,hepatic resection and hepatic resection associated with postoperative TACE groups were 3.8,7,8.2 and 15.1 mo,respectively.Significant differences were observed in the survival rates.For the surgical resection associated with postoperative TACE group,the survival rates after 1,2 and3 years were 49%,37%and 19%,respectively.These results were significantly higher than those of the other groups(P<0.05).Meanwhile,the 1,2 and 3 year survival rates for the surgical resection group were 28%,20%and 15%,whereas those for the TACE group were17.5%,0%and 0%,respectively.These values significantly increased after hepatic resection compared with those after TACE(P<0.05).CONCLUSION:Surgical resection is the most effective therapeutic strategy for HCC patients with PVTT and results in high hepatic functional reserve.For patients who can tolerate the procedure,postoperative TACE is necessary to prevent recurrence and prolong the survival period.Jia-Zhou Ye Yong-Quan Zhang Hai-Hong Ye Tao Bai Liang Ma Bang-De Xiang Le-Qun Li 2014World Journal of Gastroenterology2014,20,45:32
2Moxibustion regulates inflammatory mediators and colonic mucosal barrier in ulcerative colitis rats显示文摘AIM: To observe the efficacy and mechanism of grainsized moxibustion at different acupoints in a rat model of ulcerative colitis(UC). METHODS: Sprague-Dawley rats were randomly divided into control, UC model, grain-sized moxibustion at a single acupoint(CV 12), grain-sized moxibustion at two acupoints(CV 12 and CV 4), grain-sized moxibustion at three acupoints(CV 12, CV 4, and ST 36), and medication groups(n = 8/group). The UC model was established by enema of trinitrobenzene sulfonic acid. Direct moxibustion was used once a day for 7 d. Disease activity index(DAI) was evaluated before and after the treatment. Morphologic changes of intestinal tissue were observed under an optical microscope. The expression of tumor necrosis factor(TNF)-α and p38 mitogen-activated protein kinase(p38MAPK) in colonic tissue was detected using Western blot, and the levels of occludin and zonula occludens-1(ZO-1) m RNAs were detected using reverse transcription PCR. RESULTS: Compared with the control group, the intestinal mucosae were incomplete in the model group, glandular structures were irregular, and submucosae were edematous, hyperemic, and infiltrated with inflammatory cells. The DAI scores and expression ofTNF-α and p38 MAPK were increased significantly in the model group compared to controls(P s < 0.01), while the m RNA levels of occludin and ZO-1 were reduced significantly(P s < 0.01). Compared with the model group, colonic mucosa and the arrangement of glands were complete and regular in the treatment groups. DAI scores and the expression of TNF-α and p38 MAPK were reduced significantly in moxibustion groups compared to controls(P s < 0.01), while the m RNA levels of occludin and ZO-1 were increased significantly(P s < 0.01). The improvements in the above indices in the three acupoints group and the medication group were superior to those in the single and two acupoints groups(all P < 0.05). CONCLUSION: Reduction of TNF-α and p38 MAPK and increased expression of occludin and ZO-1 in colonic tissue represent a potential mechanism for improved intestinal mucosal tissue repair with grain-sized moxibustion.Tie-Ming Ma Na Xu Xian-De Ma Zeng-Hua Bai Xing Tao Hong-Chi Yan 2016World Journal of Gastroenterology2016,22,8:30
3Efficacy of postoperative adjuvant transcatheter arterial chemoembolization in hepatocellular carcinoma patients with microvascular invasion显示文摘AIM To investigate the efficacy and safety of postoperative adjuvant transcatheter arterial chemoembolization(PA-TACE) in preventing tumor recurrence and improving survival in Barcelona Clinic Liver Cancer(BCLC) early(A) and intermediate(B) stage hepatocellular carcinoma(HCC) patients with microvascular invasion(MVI).METHODS A total of 519 BCLC A or B HCC patients treated by liver resection alone or followed by PA-TACE between January 2012 and December 2015 were studied retrospectively. Univariate and multivariate analyses were performed to investigate the risk factors for recurrence-free survival(RFS) and overall survival(OS). Multiple logistic regression was used to identify the clinicopathological characteristics associated with MVI. The rates of RFS and OS were compared among patients with or without MVI treated with liver resection alone or followed by PA-TACE. RESULTS Univariate and multivariate analyses demonstrated that serum AFP level > 400 ng/m L, tumor size > 5 cm, tumor capsule invasion, MVI, and major hepatectomy were risk factors for poor OS. Tumor capsule invasion, MVI, tumor size > 5 cm, HBV-DNA copies > 1 x 104 IU/m L, and multinodularity were risk factors for poor RFS. Multiple logistic regression identified serum AFP level > 400 ng/m L, tumor size > 5 cm, and tumor capsule invasion as independent predictors of MVI. Both OS and DFS were significantly improved in patients with MVI who received PA-TACE as compared to those who underwent liver resection alone. Patients without MVI did not show a significant difference in OS and RFS between those treated by liver resection alone or followed by PA-TACE.CONCLUSION PA-TACE is a safe adjuvant intervention and can efficiently prevent tumor recurrence and improve the survival of BCLC early-and intermediate-stage HCC patients with MVI.Jia-Zhou Ye Jun-Ze Chen Zi-Hui Li Tao Bai Jie Chen Shao-Liang Zhu Le-Qun Li Fei-Xiang Wu 2017World Journal of Gastroenterology2017,23,41:29
4Chinese Trauma Surgeon Association for management guidelines of vacuum sealing drainage application in abdominal surgeries-Update and systematic review显示文摘Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chin ese Trauma Surge on Associati on orga nized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries.Eleven questions regarding the use of VSD in abdominal surgeries were addressed:(1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions?(2) Can VSD be preventively used for a high-risk abdominal incision w让h primary suture?(3) Can VSD be used in severely contaminated/infected abdominal surgical sites?(4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome?(5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage?(6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula?(7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess?(8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects?(9) Does VSD in crease the risk of bleeding?(10) Does VSD increase the risk of intestinal wail injury?(11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.Yang Li Pei-Yuan Li Shi-Jing Sun Yuan-Zhang Yao Zhan-Fei Li Tao Liu Fan Yang Lian-Yang Zhang Xiang-Jun Bai Jing-Shan Huo Wu-Bing He Jun Ouyang Lei Peng Ping Hu Yan-An Zhu Ping Jin Qi-Feng Shao Yan-Feng Wang Rui-Wu Dai Pei-Yang Hu Hai-Ming Chen Ge-Fei Wang Yong-Gao Wang Hong-Xu Jin Chang-Ju Zhu Qi-Yong Zhang Biao Shao Xi-Guang Sang Chang-Lin Yin 2019Chinese Journal of Traumatology2019,22,1:26
5Effects of molasses on the fermentation characteristics of mixed silage prepared with rice straw, local vegetable by-products and alfalfa in Southeast China显示文摘This experiment was conducted to study the effect of molasses on the fermentation characteristics of mixed silage ensiled rice straw and vegetable by-products with alfalfa.Mixture(202 g kg^(–1) dry matter(DM))consisting of rice straw,broccoli residue and alfalfa at the ratio of 5:4:1 was ensiled with three experimental treatments:(1)no additives(control);(2)molasses at 2.5%(M1);(3)molasses at 5%(M2)on a fresh matter basis of mixture,respectively.All treatments were packed into laboratory-scale silos,and three silos per treatment were sampled on days 1,3,5,14 and 30.The result showed that the p H value of all mixed silages decreased gradually with the time of ensiling except for the control silage,in which a significant increase(P<0.05)on day 30 occurred.The lactic acid content increased gradually with the time of ensiling and reached the highest value on day 14,and a marked decrease(P<0.05)was found in the control silage on day 30.The changes of acetic acid content showed similar pattern with lactic acid content.A trace amount of propionic and butyric acid contents were found in the three mixed silages during the fermentation period.Comparing to the control,M1 and M2 treatments improved the fermentation quality of mixed silages as indicated by higher(P<0.05)lactic acid contents and lower(P<0.05)p H and ammonia-N contents.The Flieg points also showed that M1 and M2 silages were well preserved,whereas the control silage had a bad quality.Overall,the findings of this study suggested that adding molasses could improve fermentation quality of mixed silage,and M1 was more suitable for practical application.WANG Jian CHEN Lei YUAN Xian-jun GUO Gang LI Jun-feng BAI Yun-feng SHAO Tao 2017Journal of Integrative Agriculture2017,16,3:24
6Root microbiota shift in rice correlates with resident time in the field and developmental stage显示文摘Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field(e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment.Jingying Zhang Na Zhang Yong-Xin Liu Xiaoning Zhang Bin Hu Yuan Qin Haoran Xu Hui Wang Xiaoxuan Guo Jingmei Qian Wei Wang Pengfan Zhang Tao Jin Chengcai Chu Yang Bai 2018Science China(Life Sciences)2018,61,6:24

8Role of PERK/eIF2α/CHOP Endoplasmic Reticulum Stress Pathway in Oxidized Low-density Lipoprotein Mediated Induction of Endothelial Apoptosis显示文摘Objective PERK/eI F2α/CHOP is a major signaling pathway mediating endoplasmic reticulum(ER) stress related with atherosclerosis.Oxidized LDL(ox-LDL) also induces endothelial apoptosis and plays a vital role in the initiation and progression of atherosclerosis.The present study was conducted to explore the regulatory effect of ox-LDL on PERK/e IF2α/CHOP signaling pathway in vascular endothelial cells.Methods The effects of ox-LDL on PERK and p-e IF2α protein expression of primary human umbilical vein endothelial cells(HUVECs) were investigated by Western blot analysis.PERK gene silencing and selective eI F2α phosphatase inhibitor,salubrinal were used to inhibit the process of ox-LDL induced endothelial cell apoptosis,caspase-3 activity,and CHOP mR NA level.Results Ox-LDL treatment significantly increased the expression of PERK,PERK-mediated inactivation of e IF2α phosphorylation,and the expression of CHOP,as well as the caspase-3 activity and apoptosis.The effects of ox-LDL were markedly decreased by knocking down PERK with stable transduction of lentiviral sh RNA or by selective eI F2α phosphatase inhibitor,salubrinal.Conclusion This study provides the first evidence that ox-LDL induces apoptosis in vascular endothelial cells mediated largely via the PERK/eI F2α/CHOP ER-stress pathway.It adds new insights into the molecular mechanisms underlying the pathogenesis and progression of atherosclerosis.TAO Yong Kang YU Pu Lin BAI Yong Ping YAN Sheng Tao ZHAO Shui Ping ZHANG Guo Qiang 2016Biomedical and Environmental Sciences2016,29,12:21
9Mechanism of the protective effects of noninvasive limbs preconditioning on myocardial ischemia-reperfusion injury显示文摘Background This study aimed at assessing the effect of noninvasive limb preconditioning on myocardial infarct size, and deter mining whether nitric oxide and neurogenic pathway play an important role in the mechanism of acute remote ischemic preconditioning (IPC). Methods Forty Wistar rats were randomly divided into fo ur experimental groups. In Group Ⅰ, the rats underwent 30-minute occlusion of the left anterior descending coronary artery, and 120-minute reperfusion. In Group PL, the rats underwent four cycles of 5-minute occlusion and reperfusion of both h ind limbs using a tourniquet before the experiment was continued as in Group Ⅰ. In Group P L-N and Group P L-H, we administered L-nitro-arginine meth yl ester (L-NAME) 10 mg/kg or hexamethonium chloride 20 mg/kg intravenously, 10 minutes before IPC. Infarct size as a percentage of the area at risk was deter mine d by triphenyltetrazolium chloride staining. Results There were no statistically significant differences in mean arterial pressure and heart rate amo ng these groups at any time point during the experiment (P>0.05). The myo cardial infarct size (IS) was decreased significantly in Group PL and Group P  L-H compared with Group Ⅰ, and the IS/AAR was 34.5%±7.6%, 35.9%±8. 6 % and 58.5%±8.5%, respectively (P<0.05). The IS/AAR was 49.1%±6.5% in Group P L-N, and there was no significant difference compared with Grou p Ⅰ (P>0.05). Conclusions Noninvasive limb IPC is effective in protecting the myocardium from ischemia reperfusion injury. Nitric oxide plays an important r ole in the mechanism of acute remote IPC, in which the neurogenic pathway is not involved .CHEN Xiao-guang WU Bin-yang WANG Jun-ke BAI Tao 2005Chinese Medical Journal2005,,20:18
10Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C.Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang 2019Research in Astronomy and Astrophysics2019,19,11:17
11Qingfei Xiaoyan Wan,a traditional Chinese medicine formula, ameliorates Pseudomonas aeruginosa–induced acute lung inflammation by regulation of PI3K/AKT and Ras/MAPK pathways显示文摘Gram-negative pathogen–induced nosocomial infections and resistance are a most serious menace to global public health. Qingfei Xiaoyan Wan(QF), a traditional Chinese medicine(TCM)formula, has been used clinically in China for the treatment of upper respiratory tract infections, acute or chronic bronchitis and pulmonary infection. In this study, the effects of QF on Pseudomonas aeruginosa–induced acute pneumonia in mice were evaluated. The mechanisms by which four typical antiinflammatory ingredients from QF, arctigenin(ATG), cholic acid(CLA), chlorogenic acid(CGA) and sinapic acid(SPA), regulate anti-inflammatory signaling pathways and related targets were investigated using molecular biology and molecular docking techniques. The results showed that pretreatment with QF significantly inhibits the release of cytokines(TNF-α and IL-6) and chemokines(IL-8 and RANTES),reduces leukocytes recruitment into inflamed tissues and ameliorates pulmonary edema and necrosis. In addition, ATG was identified as the primary anti-inflammatory agent with action on the PI3K/AKT and Ras/MAPK pathways. CLA and CGA enhanced the actions of ATG and exhibited synergistic NF-κB inactivation effects possibly via the Ras/MAPK signaling pathway. Moreover, CLA is speculated to target FGFR and MEK firstly. Overall, QF regulated the PI3K/AKT and Ras/MAPK pathways to inhibit pathogenic bacterial infections effectively.Yuanyuan Hou Yan Nie Binfeng Cheng Jin Tao Xiaoyao Ma Min Jiang Jie Gao Gang Bai 2016Acta Pharmaceutica Sinica B2016,6,3:17
12COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu 2021China CDC weekly2021,3,21:16
13Old canalicular laceration repair:a retrospective study of the curative effects and prognostic factors显示文摘AIM: To investigate the epidemiology and surgical outcomes of old canalicular laceration and analyze the variables impacting on the prognosis of reparation. METHODS: A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS: Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old(ranged from 3 to 63 years old). The 110 patients(74.32%) were male and 127 patients(85.81%) were adults(≥18 years old). The old upper, lower, and bicanalicular lacerations were found in 5(3.38%), 39(26.35%), and 104 patients(70.27%), respectively. The mechanism of old injury was primarily due to motor vehicle accidents(n=53, 35.81%). The mean time from injury to repair was 43.61mo(ranged from 1 to 360mo). Associated old ocular and orbit injuries were found in 65 patients(43.92%), and chronic dacryocystitis in 18 patients(12.16%). The main cause of delayed repair was that doctors or patients didn't pay attention to the canalicular laceration because of the concurrent severe injuries(n=71, 47.97%). Totally 136 patients(91.89%) with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients(13.51%) were combined with dacryocystorhinostomy. In these cases, 132 patients(97.06%) attained anatomic success, 121 patients(88.97%) reported no epiphora(functional success), 11 patients(8.09%) reported significant epiphora anesis(functional improvement), and 4(2.94%) reported no significant anesis(functional failure). Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair.CONCLUSION: The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration.Fang Bai Hai Tao Yan Zhang Peng Wang Cui Han Yi-Fei Huang Ye Tao 2017International Journal of Ophthalmology(English edition)2017,10,6:15
14One-stitch anastomosis through the skin with bicanalicular intubation:a modified approach for repair of bicanalicular laceration显示文摘AIM:To evaluate the efficacy and safety of one-stitch anastomosis through the skin with bicanalicular silicone tube intubation in repairing of bicanalicular laceration.METHODS:The clinical data of 15 consecutive patients with both superior and inferior canalicular laceration in one eye who underwent surgical repair using one-stitch anastomosis through the skin and bicanalicular stent were retrospective studied.All the operations were performed under surgical microscope,5-0 silk sutures were used and were with bicanalicular silicone tube(diameter was 8mm) intubation,for one lacerated canaliculi one-stitch anastomosis through the skin.The stents were left in place for 3 months postoperatively and then removed.The follow-up period was 3-36 months(average 14 months). RESULTS:In 15 patients,13 patients were cured entirely,1 patient was meliorated,1 patient with no effects.All patients had got good recovery of eyelid laceration with no traumatic deformity in eyelid and canthus.Complication was seen in one case,for not followed the doctor's guidance to come back to hospital to had the suture removed on the 7thday after operation,when he came at the 15thday,the inferior canalicular wall and eyelid skin were corroded by the suture caused 2mm wound,and the inside silicone tube was exposed,a promptly repair with 10-0 nylon suture was done,the wound healed in a week.There were no early tube protrusions and punctal slits in the patients.CONCLUSION:One-stitch anastomosis through the skin with bicanalicular silicone tube intubation is a good method in repair of bicanalicular laceration in one eye,the cut ends can be anastomosed directly,and with excellent cosmetic results,it is acceptable for the patients.For there is no suture remained in the wound permanently,so there is no suture-related granuloma which may cause obstruction or stenosis of canaliculi.It is simple,economical,effective and safe.Hai Tao Peng Wang Cui Han Jian Zhang Fang Bai Zhao-Yan He 2013International Journal of Ophthalmology(English edition)2013,6,5:14
15Comprehensive treatments for hepatocellular carcinoma with tumor thrombus in major portal vein显示文摘AIM: To evaluate the efficacy of transcatheter arterial chemoembolisation(TACE) compared with surgical intervention and sorafenib for treatment of hepatocellular carcinoma(HCC) in patients with tumor thrombus extending to the main portal vein.METHODS: From 2009 to 2013, a total of 418 HCC patients with tumor thrombus extending to the main portal vein were enrolled in this study and divided into four groups. These groups underwent different treatments as follows: TACE(n = 307), surgical intervention(n = 54), sorafenib(n = 15) and palliativetreatment(n = 42). Overall survival rates were determined by Kaplan-Meier method, and differences between the groups were identified through log-rank analysis. Cox's proportional hazard model was used to identify the risk factors for survival.RESULTS: The mean survival periods for patients in the TACE, surgical intervention, sorafenib and palliative treatment groups were 10.39, 4.13, 5.54 and 2.82 mo, respectively. For the TACE group, the 3-, 6-, 12-and 24-mo survival rates were 94.1%, 85.9%, 51.5% and 0.0%, respectively. The corresponding rates were 60.3%, 22.2%, 0.0% and 0.0% for the surgical intervention group and 50.9%, 29.5%, 0.0% and 0.0% for the sorafenib group. Evidently, the results in the TACE group were significantly higher than those in the other groups(P < 0.0001). Furthermore, no significant difference among survival rates was observed between TACE with/without sorafenib(10.22 mo vs 10.52 mo, P = 0.615). No significant difference in survival rates was also found among the surgical intervention, sorafenib and palliative treatment groups(P > 0.05). These values significantly increased after TACE with/without sorafenib compared with other treatments(P < 0.05).CONCLUSION: For HCC patients with tumor thrombus extending to the main portal vein, TACE can yield a higher survival rate than surgical intervention or sorafenib treatment.Hai-Hong Ye Jia-Zhou Ye Zhi-Bo Xie Yu-Chong Peng Jie Chen Liang Ma Tao Bai Jun-Ze Chen Zhan Lu Hong-Gui Qin Bang-De Xiang Le-Qun Li 2016World Journal of Gastroenterology2016,22,13:14
16Health-related quality of life in gastroesophageal reflux patients with noncardiac chest pain: Emphasis on the role of psychological distress显示文摘AIM To investigate the effects of depression and anxiety on health-related quality of life(QoL)in gastroesophageal reflux disease(GERD)patients and those suffering from cardiac(CCP)and noncardiac(NCCP)chest pain in Wuhan,China.METHODS In this cross-sectional study,a total of 358 consecutive patients with GERD were enrolled in Wuhan,China,of which 176 subjects had complaints of chest pain.Those with chest pain underwent coronary angiography and were divided into a CCP group(52 cases)and NCCP group(124 cases).Validated GERD questionnaires were completed,and the 36-item Short-Form Health Survey and Hospital Anxiety/Depression Scale were used for evaluation of Qo L and psychological symptoms,respectively.RESULTS There were similar ratios and levels of depression and anxiety in GERD with NCCP and CCP.However,the QoL was obviously lower in GERD with CCP than NCCP(48.34±17.68 vs 60.21±20.27,P<0.01).In the GERD-NCCP group,rather than the GERD-CCP group,the physical and mental QoL were much poorer in subjects with depression and/or anxiety than those without anxiety or depression.Anxiety and depression had strong negative correlations with both physical and mental health in GERD-NCCP(all P<0.01),but only a weak relationship with mental components of QoL in GERD-CCP.CONCLUSION High levels of anxiety and depression may be more related to the poorer QoL in GERD patients with NCCP than those with CCP.This highlights the importance of evaluation and management of psychological impact for improving QoL in GERD-NCCP patients.Lei Zhang Lei Tu Jie Chen Jun Song Tao Bai Xue-Lian Xiang Rui-Yun Wang Xiao-Hua Hou 2017World Journal of Gastroenterology2017,23,1:14
17Punicalagin ameliorates collagen-induced arthritis by downregulating M1 macrophage and pyroptosis via NF-κB signaling pathway显示文摘Rheumatoid arthritis(RA)is a chronic inflammatory disease that eventually leads to disability.Inflammatory cell infiltration,severe joint breaking and systemic bone loss are the main clinical symptoms.In this study,we established a collagen-induced arthritis(CIA)model and found a large number of M1 macrophages and pyroptosis,which are important sources of proinflammatory cytokines.Punicalagin(PUN)is an active substance extracted from pomegranate peel.We found that it inhibited joint inflammation,cartilage damage and systemic bone destruction in CIA mice.PUN effectively alleviated the high expression of inflammatory cytokines in synovial tissue in vivo.PUN treatment shifted macrophages from the M1 phenotype to the M2 phenotype after stimulation with lipopolysaccharide(LPS)and interferon(IFN)-γ.The expression of inducible nitric oxide synthase(i NOS)and other proinflammatory cytokines released by M1 macrophages was decreased in the PUN treatment group.However,simultaneously,the expression of markers of anti-inflammatory M2 macrophages,such as arginase(Arg)-1 and interleukin(IL)-10,was increased.In addition,PUN treatment attenuated pyroptosis by downregulating the expression of NLRP3 and caspase-1,thereby preventing inflammatory cell death resulting from the release of IL-1βand IL-18.Mechanistically,PUN inhibited the activation of receptor activators of the nuclear factor-κB(NF-κB)signaling pathway,which contributes to M1 polarization and pyroptosis of macrophages.We concluded that PUN ameliorated pathological inflammation by inhibiting M1 phenotype polarization and pyroptosis and has great potential as a therapeutic treatment for human RA.Gaoran Ge Jiaxiang Bai Qing Wang Xiaolong Liang Huaqiang Tao Hao Chen Minggang Wei Junjie Niu Huilin Yang Yaozeng Xu Yuefeng Hao Yi Xue Dechun Geng 2022Science China(Life Sciences)2022,65,3:14
18Optimal Energy Flow and Nodal Energy Pricing in Carbon Emission-embedded Integrated Energy Systems显示文摘Green energy is driving the evolutions of energy industry and carbon emission is becoming an important concern.Considering the increasing couplings among various energy sectors,this paper investigates multi-period optimal energy flow and energy pricing in carbon-emission embedded integrated energy systems,including electricity,natural gas,and district heating networks.Firstly,an optimal scheduling model of integrated energy systems was proposed in this paper.The models of DC power flow,natural gas pipeline flow and heating network energy flow are presented and linearized for the optimization problem.Natural gas-fired generators and combined heat and power(CHP)units are modeled as coupling components of electricitygas and electricity-heating networks.Then,based on the optimal scheduling model,the locational marginal prices(LMP)for electricity,natural gas and heating network are determined.Moreover,the carbon emission caused by energy production has been taken into account in the optimal scheduling and energy pricing process.Finally,case studies on a combined network consisting of IEEE 39-bus system,Belgium 20-node natural gas system and 6-node heating system demonstrate the effectiveness of the proposed model and the impacts of carbon emission on system scheduling and LMP.Tao Jiang Hongwei Deng Linquan Bai Rufeng Zhang Xue Li Houhe Chen 2018CSEE Journal of Power and Energy Systems2018,4,2:13

20Day-ahead Scheduling of Multi-carrier Energy Systems with Multi-type Energy Storages and Wind Power显示文摘The integration of large-scale wind power brings challenges to the operation of integrated energy systems(IES).In this paper,a day-ahead scheduling model for IES with wind power and multi-type energy storage is proposed in a scenario-based stochastic programming framework.The structure of the IES consists of electricity,natural gas,and heating networks which are all included in the model.Operational constraints for IES incorporating multi-type energy storage devices are also considered.The constraints of the electricity network,natural gas network and heating network are formulated,and non-linear constraints are linearized.The calculation method for the correlation of wind speed between wind farms based on historical data is proposed.Uncertainties of correlated wind power were represented by creating multiple representative scenarios with different probabilities,and this was done using the Latin hyper-cube sampling(LHS)method.The stochastic scheduling model is formulated as a mixed integer linear programming(MILP)problem with the objective function of minimizing the total expected operation cost.Numerical results on a modified PJM 5-bus electricity system with a seven-node natural gas system and a six-node heating system validate the proposed model.The results demonstrate that multi-type energy storage devices can help reduce wind power curtailments and improve the operational flexibility of IES.Rufeng Zhang Tao Jiang Guoging Li Houhe Chen Xue Li Linquan Bai Hantao Cui 2018CSEE Journal of Power and Energy Systems2018,4,3:13
