1Active tectonic blocks and strong earthquakes in the continent of China显示文摘The primary pattern of the late Cenozoic to the present tectonic deformation of China is characterized by relative movements and interactions of tectonic blocks. Active tectonic blocks are geological units that have been separated from each other by active tectonic zones. Boundaries between blocks are the highest gradient of differential movement. Most of tectonic activity occurs on boundaries of the blocks. Earthquakes are results of abrupt releases of accumulated strain energy that reaches the threshold of strength of the earth's crust. Boundaries of tectonic blocks are the locations of most discontinuous deformation and highest gradient of stress accumulation, thus are the most likely places for strain energy accumulation and releases, and in turn, devastating earthquakes. Almost all earthquakes of magnitude greater than 8 and 80%-90% of earthquakes of magnitude over 7 occur along boundaries of active tectonic blocks. This fact indicates that differential movements and interactions of active tectonic blocks are the primary mechanism for the occurrences of devastating earthquakes.ZHANG Peizhen (张培震) DENG Qidong (邓起东) ZHANG Guomin (张国民) MA Jin (马 瑾) GAN Weijun (甘卫军) MIN Wei (闵 伟) MAO Fengying (毛凤英) WANG Qi (王 琪) 2003Science China Earth Sciences2003,46,z2:239
2Prognostic factors and failure patterns in non-metastatic nasopharyngeal carcinoma after intensity-modulated radiotherapy显示文摘Background: The prognostic values of staging parameters require continual re?assessment amid changes in diag?nostic and therapeutic methods. This study aimed to identify the prognostic factors and failure patterns of non?meta?static nasopharyngeal carcinoma(NPC) in the intensity?modulated radiotherapy(IMRT) era.Methods: We reviewed the data from 749 patients with newly diagnosed, biopsy?proven, non?metastatic NPC in our cancer center(South China, an NPC endemic area) between January 2003 and December 2007. All patients under?went magnetic resonance imaging(MRI) before receiving IMRT. The actuarial survival rates were estimated using the Kaplan–Meier method, and survival curves were compared using the log?rank test. Multivariate analyses with the Cox proportional hazards model were used to test for the independent prognostic factors by backward eliminating insigniicant explanatory variables.Results: The 5?year occurrence rates of local failure, regional failure, locoregional failure, and distant failure were 5.4, 3.0, 7.4, and 17.4%, respectively. The 5?year survival rates were as follows: local relapse?free survival, 94.6%; nodal relapse?free survival, 97.0%; distant metastasis?free survival, 82.6%; disease?free survival, 75.1%; and overall survival, 82.0%. Multivariate Cox regression analysis revealed that orbit involvement was the only signiicant prognostic fac?tor for local failure(P = 0.011). Parapharyngeal tumor extension, retropharyngeal lymph node involvement, and the laterality, longest diameter, and Ho's location of the cervical lymph nodes were signiicant prognostic factors for both distant failure and disease failure(all P < 0.05). Intracranial extension had signiicant prognostic value for distant failure(P = 0.040).Conclusions: The key failure pattern for NPC was distant metastasis in the IMRT era. With changes in diagnostic and therapeutic technologies as well as treatment modalities, the signiicant prognostic parameters for local control have also been altered substantially.Yan-Ping Mao Ling-Long Tang Lei Chen Ying Sun Zhen-Yu Qi Guan-Qun Zhou Li-Zhi Liu Li Li Ai-Hua Lin Jun Ma 2016Chinese Journal of Cancer2016,35,12:39
3Expenditure and financial burden for the diagnosis and treatment of colorectal cancer in China:a hospital.based,multicenter,cross-sectional survey显示文摘Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective.Hui-Yao Huang Ju-Fang Shi Lan-Wei Guo Ya-Na Bai Xian-Zhen Liao Guo-iangLiu A-Yan Mao Jian-Song Ren Xiao-Jie Sun Xin-Yu Zhu Le Wang Bing-Bing Song Ling-Bin Du Lin Zhu Ji-Yong Gong Qi Zhou Yu-Qin Liu Rong Cao Ling Mai Li Lan Xiao-Hua Sun Ying Ren Jin-Yi Zhou Yuan-Zheng Wang Xiao Qi Pei-An Lou Dian Shi Ni Li Kai Zhang Jie He Min Dai 2017Chinese Journal of Cancer2017,36,8:25
4Metastasis-associated protein 1 induces VEGF-C and facilitates lymphangiogenesis in colorectal cancer显示文摘AIM:To study the correlation between high metastasisassociated protein 1(MTA1)expression and lymphangiogenesis in colorectal cancer(CRC)and its role in production of vascular endothelial growth factor-C(VEGF-C). METHODS:Impact of high MTA1 and VEGF-C expression levels on disease progression and lymphovasculardensity(LVD,D2-40-immunolabeled)in 81 cases of human CRC was evaluated by immunohistochemistry. VEGF-C mRNA and protein expressions in human LoVo and HCT116 cell lines were detected by real-time polymerase chain reaction and Western blotting,respectively,with a stable expression vector or siRNA. RESULTS:The elevated MTA1 and VEGF-C expression levels were correlated with lymph node metastasis and Dukes stages(P<0.05).Additionally,high MTA1 expression level was correlated with a large tumor size(P< 0.05).A significant correlation was found between MTA1 and VEGF-C protein expressions in tumor cells(r=0.371, P<0.05).Similar to the VEGF-C expression level,high MTA1 expression level was correlated with high LVD in CRC(P<0.05).Furthermore,over-expression of MTA1 significantly enhanced the VEGF-C mRNA and protein expression levels,whereas siRNAs-knocked down MTA1 decreased the VEGF-C expression level. CONCLUSION:MTA1,as a regulator of tumor-associated lymphangiogenesis,promotes lymphangiogenesis in CRC by mediating the VEGF-C expression.Bin Du Zhen-Yu Yang Xue-Yun Zhon Mao Fang Yong-Rong Yan Guo-Long Qi Yun-Long Pan Xu-Long Zhou 2011World Journal of Gastroenterology2011,17,9:23

13Effect of human umbilical cord-derived mesenchymal stem cells on lung damage in severe COVID-19 patients:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Treatment of severe Coronavirus Disease 2019(COVID-19)is challenging.We performed a phase 2 trial to assess the efficacy andsafety of human umbilical cord-mesenchymal stem cells(UC-MScs)to treat severe coViD-19 patients with lung damage,based onour phase 1 data.In this randomized,double-blind,and placebo-controlled trial,we recruited 101 severe coVID-19 patients withlung damage.They were randomly assigned at a 2:1 ratio to receive either UC-MSCs(4×10^(7)cells per infusion)or placebo on day 0,3,and 6.The primary endpoint was an altered proportion of whole lung lesion volumes from baseline to day 28.Other imagingoutcomes,6-minute walk test(6-MWT),maximum vital capacity,diffusing capacity,and adverse events were recorded and analyzed.In all,100 COVID-19 patients were finally received either UC-MSCs in=65)or placebo(n=35).UC-MSCs administrationexerted numerical improvement in whole lung lesion volume from baseline to day 28 compared with the placebo(the mediandifference was-13.31%,95%Cl-29.14%,2.13%,P=0.08).UC-MSCs significanty reduced the proportions of solid componentlesion volume compared with the placebo(median difference:-15.45%;95%CI-30.82%,-0.39%;P=0.043).The 6-MWT showedan increased distance in patients treated with UC-MSCs(difference:27.00 m;95%CI 0.00,57.00;P=0.057).The incidence of adverseevents was similar in the two groups.These results suggest that UC-MSCs treatment is a safe and potentially effective therapeuticapproach for COVID-19 patients with lung damage.A phase 3 trial is required to evaluate effects on reducing mortality andpreventing long-term pulmonary disability.Lei Shi Hai Huang Xuechun Lu Xiaoyan Yan Xiaojing Jiang Ruonan Xu Siyu Wang Chao Zhang Xin Yuan Zhe Xu Lei Huang Jun-Liang Fu Yuanyuan Li Yu Zhang Wei-Qi Yao Tianyi Liu Jinwen Song Liangliang Sun Fan Yang Xin Zhang Bo Zhang Ming Shi Fanping Meng Yanning Song Yongpei Yu Jiqiu Wen Qi Li Qing Mao Markus Maeurer Alimuddin Zumla Chen Yao Wei-Fen Xie Fu-Sheng Wang 2021Signal Transduction and Targeted Therapy2021,6,3:13
14Updated experiences with minimally invasive Mc Keown esophagectomy for esophageal cancer显示文摘AIM: To update our experiences with minimally invasive Mc Keown esophagectomy for esophageal cancer.METHODS: we retrospectively reviewed the medical records of 445 consecutive patients who underwent minimally invasive Mc Keown esophagectomy between January 2009 and July 2015 at the Cancer Hospital of Chinese Academy of Medical Sciences and used 103 patients who underwent open Mc Keown esophagectomy in the same period as controls. Among 375 patients who underwent total minimally invasive Mc Keown esophagectomy, 180 in the early period were chosen for the study of learning curve of total minimally invasive Mc Keown esophagectomy. These 180 minimally invasive Mc Keown esophagectomies performed by five surgeons were divided into three groups according to time sequence as group 1(n = 60), group 2(n = 60) and group 3(n = 60).RESULTS: Patients who underwent total minimally invasive Mc Keown esophagectomy had significantly less intraoperative blood loss than patients who underwent hybrid minimally invasive Mc Keown esophagectomy or open Mc Keown esophagectomy(100 ml vs 300 ml vs 200 ml, P = 0.001). However, there were no significant differences in operation time, number of harvested lymph nodes, or postoperative morbidity includingincidence of pulmonary complication and anastomotic leak between total minimally invasive Mc Keown esophagectomy, hybrid minimally invasive Mc Keown esophagectomy and open Mc Keown esophagectomy groups. There were no significant differences in 5-year survival between these three groups(60.5% vs 47.9% vs 35.6%, P = 0.735). Patients in group 1 had significantly longer duration of operation than those in groups 2 and 3. There were no significant differences in intraoperative blood loss, number of harvested lymph nodes, or postoperative morbidity including incidence of pulmonary complication and anastomotic leak between groups 1, 2 and 3.CONCLUSION: Total minimally invasive Mc Keown esophagectomy was associated with reduced intraoperative blood loss and comparable short term and long term survival compared with hybrid minimally invasive Mc Keown esophagectomy or open Mckeown esophagectomy. At least 12 cases are needed to master total minimally invasive Mc Keown esophagectomy in a high volume center.Ju-wei Mu Shu-geng gao Qi Xue You-Sheng Mao Da-li wang Jun Zhao Yu-Shun gao Jin-feng Huang Jie He 2015World Journal of Gastroenterology2015,21,45:10

16Adaptable hydrogel with reversible linkages for regenerative medicine:Dynamic mechanical microenvironment for cells显示文摘Hydrogels are three-dimensional platforms that serve as substitutes for native extracellular matrix.These materials are starting to play important roles in regenerative medicine because of their similarities to native matrix in water content and flexibility.It would be very advantagoues for researchers to be able to regulate cell behavior and fate with specific hydrogels that have tunable mechanical properties as biophysical cues.Recent developments in dynamic chemistry have yielded designs of adaptable hydrogels that mimic dynamic nature of extracellular matrix.The current review provides a comprehensive overview for adaptable hydrogel in regenerative medicine as follows.First,we outline strategies to design adaptable hydrogel network with reversible linkages according to previous findings in supramolecular chemistry and dynamic covalent chemistry.Next,we describe the mechanism of dynamic mechanical microenvironment influence cell behaviors and fate,including how stress relaxation influences on cell behavior and how mechanosignals regulate matrix remodeling.Finally,we highlight techniques such as bioprinting which utilize adaptable hydrogel in regenerative medicine.We conclude by discussing the limitations and challenges for adaptable hydrogel,and we present perspectives for future studies.Zongrui Tong Lulu Jin Joaquim Miguel Oliveira Rui LReis Qi Zhong Zhengwei Mao Changyou Gao 2021Bioactive Materials2021,6,5:8
17Application of video-assisted thoracic surgery in the standard operation for thoracic tumors显示文摘Objective: To evaluate the short-term outcomes of video-assisted thoracic surgery (VATS) for thoracic tumors. Methods: The data of 1,790 consecutive patients were retrospectively reviewed. These patients underwent VATS pulmonary resections, VATS esophagectomies, and VATS resections of mediastinal tumors or biopsies at the Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and January 2012. Results: There were 33 patients converted to open thoracotomy (OT, 1.84%). The overall morbidity and mortality rate was 2.79% (50/1790) and 0.28% (5/1790), respectively. The overall hospitalization and chest tube duration were shorter in the VATS lobectomy group (n=949) than in the open thoracotomy (OT) lobectomy group (n=753). There were no significant differences in morbidity rate, mortality rate and operation time between the two groups. In the esophageal cancer patients, no significant difference was found in the number of nodal dissection, chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS esophagectomy group (n=81) and open esophagectomy group (n=81). However, the operation time was longer in the VATS esophagectomy group. In the thymoma patients, there was no significant difference in the chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS thymectomy group (n=41) and open thymectomy group (n=41). However, the operation time was longer in the VATS group. The median tumor size in the VATS thymectomy group was comparable with that in the OT group. Conclusions: In early-stage (I/II) non-small cell lung cancer patients who underwent lobectomies, VATS is comparable with the OT approach with similar short-term outcomes. In patients with resectable esophageal cancer, VATS esophagectomy is comparable with OT esophagectomy with similar morbidity and mortality. VATS thymectomy for Masaoka stage I and II thymoma is feasible and safe, and tumor size is not contraindicated. Longer follow-ups are needed to determine the oncologic equivalency of VATS lobectomy, esophagectomy, and thymectomy for thymoma vs. OT.Ju-Wei Mu Gui-Yu Chen Ke-Lin Sun Da-Wei Wang Bai-Hua Zhang Ning Li Fang Lv You-Sheng Mao Qi Xue Shu-Geng Gao Jun Zhao Da-Li Wang Zhi-Shan Li Wen-Dong Lei Yu-Shun Gao Liangze Zhang Jin-Feng Huang Kang Shao Kai Su Kun Yang Liang Zhao Fei-Yue Feng Yong-Gang Wang Jian Li Jie He 2013Cancer Biology & Medicine2013,10,1:8
18Neurotoxic role of interleukin-17 in neural stem cell differentiation after intracerebral hemorrhage显示文摘Interleukin 17(IL-17)and its main producer,T cell receptorγδcells,have neurotoxic effects in the pathogenesis of intracerebral hemorrhage(ICH),aggravating brain injuries.To investigate the correlation between IL-17 and ICH,we dynamically screened serum IL-17 concentrations using enzyme-linked immunosorbent assay and explored the clinical values of IL-17 in ICH patients.There was a significant negative correlation between serum IL-17 level and neurological recovery status in ICH patients(r=–0.498,P<0.01).To study the neurotoxic role of IL-17,C57 BL/6 mice were used to establish an ICH model by injecting autologous blood into the caudate nucleus.Subsequently,the mice were treated with mouse neural stem cells(NSCs)and/or IL-17 neutralizing antibody for 72 hours.Flow cytometry,brain water content detection,Nissl staining,and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling results indicated that NSC transplantation significantly reduced IL-17 expression in peri-hematoma tissue,but there was no difference in T cell receptorγδcells.Compared with the ICH group,there were fewer apoptotic bodies and more Nissl bodies in the ICH+NSC group and the ICH+NSC+IL-17 group.To investigate the potential effect of IL-17 on directional differentiation of NSCs,we cultured mouse NSCs(NE-4 C)alone or co-cultured them with T cell receptorγδcells,which were isolated from mouse peripheral blood mononuclear cells,for 7 days.The results of western blot assays revealed that IL-17 secreted by T cell receptorγδcells reduced the differentiation of NSCs into astrocytes and neurons,while IL-17 neutralization relieved the inhibition of directional differentiation into astrocytes rather than neurons.In conclusion,serum IL-17 levels were elevated in the early stage of ICH and were negatively correlated with outcome in ICH patients.Animal experiments and cytological investigations therefore demonstrated that IL-17 probably has neurotoxic roles in ICH because of its inhibitory effects on the directional differentiation of NSCs.The application of IL-17 neutralizing antibody may promote the directional differentiation of NSCs into astrocytes.This study was approved by the Clinical Research Ethics Committee of Anhui Medical University of China(For human study:Approval No.20170135)in December 2016.All animal handling and experimentation were reviewed and approved by the Institutional Animal Care and Use Committee of Anhui Medical University(approval No.20180248)in December 2017.Lu Gao Ping-Ping Li Tian-Yu Shao Xiang Mao Hao Qi Bing-Shan Wu Ming Shan Lei Ye Hong-Wei Cheng 2020Neural Regeneration Research2020,15,7:8
19Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
20Taurochenodeoxycholic acid mediates cAMP-PKA-CREB signaling pathway显示文摘Taurochenodeoxycholic acid(TCDCA)is one of the main effective components of bile acid,playing critical roles in apoptosis and immune responses through the TGR5 receptor.In this study,we reveal the interaction between TCDCA and TGR5 receptor in TGR5-knockdown H1299 cells and the regulation of inflammation via the cyclic adenosine monophosphate(cAMP)-protein kinase A(PKA)-cAMP response element binding(CREB)signal pathway in NR8383 macrophages.In TGR5-knockdown H1299 cells,TCDCA significantly activated cAMP level via TGR5 receptor,indicating TCDCA can bind to TGR5;in NR8383 macrophages TCDCA increased cAMP content compared to treatment with the adenylate cyclase(AC)inhibitor SQ22536.Moreover,activated cAMP can significantly enhance gene expression and protein levels of its downstream proteins PKA and CREB compared with groups of inhibitors.Additionally,TCDCA decreased tumour necrosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-6,IL-8 and IL-12 through nuclear factor kappa light chain enhancer of activated B cells(NF-κB)activity.PKA and CREB are primary regulators of anti-inflammatory and immune response.Our results thus demonstrate TCDCA plays an essential anti-inflammatory role via the signaling pathway of cAMP-PKA-CREB induced by TGR5 receptor.QI You-Chao DUAN Guo-Zhen MAO Wei LIU Qian ZHANG Yong-Liang LI Pei-Feng 2020Chinese Journal of Natural Medicines2020,18,12:8
