1Laparoscopic total mesorectal excision of low rectal cancer with preservation of anal sphincter:A report of 82 cases显示文摘AIM: To assess the feasibility and efficacy of laparoscopic total mesorectal excision (LTME) of low rectal cancer with preservation of anal sphincter.METHODS: From June 2001 to June 2003, 82 patients with low rectal cancer underwent laparoscopic total mesorectal excision with preservation of anal sphincter. The lowest edge of tumors was below peritoneal reflection and 1.5-7 cm from the dentate line (1.5-5 cm in 48 cases, 5-7 cm in 34 cases).RESULTS: LTME with anal sphincter preservation was performed on 82 randomized patients with low rectal cancer, and 100 % sphincter preservation rate was achieved. There were 30 patients with laparoscopic low anterior resection (LLAR) at the level of the anastomosis below peritoneal reflection and 2 cm above from the dentate line; 27 patients with laparoscopic ultralow anterior resection (LULAR) at the level of anastomoses 2 cm below from the dentate line; and 25 patients with laparoscopic coloanal anastomoses (LC AA) at the level of the anastomoses at or below the dentate line. No defunctioning ileostomy was created in any case. The mean operating time was 120 minutes (ranged from 110-220 min), and the mean operative blood loss was 20 mL (ranged from 5-120 mL).Bowel function was restored and diet was resumed on day 1 or 2 after operation. The mean hospital stay was 8 days (ranged from 5-14). Postoperative analgesics were used in 45 patients. After surgery, 2 patients had urinary retention, one had anastomotic leakage, and another 2patients had local recurrence one year later. No interoperative complication was observed.CONCLUSION: LTME with preservation of anal sphincter is a feasible, safe and minimally invasive technique with less postoperative pain and rapid recovery, and importantly, it has preserved the function of the sphincter.Zong-Guang Zhou Zhao Wang Yong-Yang Yu Ye Shu Zhong Cheng Li Li Wen-Zhang Lei Tian-Cai Wang Department of General Surgery and Institute of Digestive Surgery,West China Hospital,Sichuan University,Chengdu 610041,Sichuan Province,China 2003World Journal of Gastroenterology2003,9,7:33
2Preoperative assessment of hilar cholangiocarcinoma:combination of cholangiography and CT angiography显示文摘BACKGROUND:Hilar cholangiocarcinoma is one of the most difficult carcinomas to manage because of the location of the main tumor at the hepatic hilus and the complex anatomy of the biliary,arterial,and portal systems.To plan an operation,it is important to acquire accurate information about the relationship between hilar cholangiocarcinoma and adjacent vessels.This study aimed to evaluate the clinical value of cholangiography combined with spiral CT three-dimensional (3D)angiography for a preoperative assessment of hilar cholangiocarcinoma. METHODS:From March 2007 to August 2009,cholangiography was performed in 13 patients with hilar cholangiocarcinoma. Meanwhile,contrast-enhanced abdominal scanning was performed using 16-slice spiral CT,and the 3D images of the hepatic artery and portal vein were acquired.The level and range of invasion of the hepatic artery,the portal vein,and the bile duct,the preoperative Bismuth classification,and T-staging were recorded and compared with those after surgical exploration. RESULTS:The hepatic artery and portal vein were recon- structed successfully in all these patients.Percutaneous transhepatic cholangiography was performed in 9 patients,endoscopic retrograde cholangiopancreatography in 1,and magnetic resonance cholangiopancreatography in 3.The CT angiography records of invasion of the hepatic artery were consistent with the results of explorations in these patients. The data from 5 of the 13 patients were consistent with those on invasion of the portal vein.The results of the Bismuth classification and the T-staging system were consistent with those of surgical exploration in 12 of the 13 patients.Seven of 8 patients who were estimated to be suitable for operation based on images were curatively treated and 5 who were judged to be unsuitable for curative operation by cholangiography and CT angiography were confirmed intraoperatively and underwent palliative procedures. CONCLUSIONS:Cholangiography combined with multi-slice spiral 3D CT angiography can satisfactorily delineate the local invasion of hilar cholangiocarcinoma and accurately evaluate the resectability.This approach,therefore,contributes to the planning of safe operation.Yu, Shi-An Zhang, Cheng Zhang, Jia-Min Mao, Gen-Jun Xu, Long-Tang Wu, Xiao-Kang Shu, Jin-Er Lv, Guang-Hong Zheng, Zhang-Dong 2010Hepatobiliary & Pancreatic Diseases International2010,9,2:15

4Bedaquiline-containing regimens in patients with pulmonary multidrug-resistant tuberculosis in China:focus on the safety显示文摘Background:World Health Organization recommends countries introducing new drug and short treatment regimen for drug resistant tuberculosis(DR-TB)should develop and implement a system for active pharmacovigilance that allows for detection,reporting and management of adverse events.The aim of the study is to evaluate the frequency and severity of adverse events(AEs)of bedaquiline-containing regimen in a cohort of Chinese patients with multidrug-resistant(MDR)/extensively drug-resistant(XDR)-TB based on active drug safety monitoring(aDSM)system of New Drug Introduction and Protection Program(NDIP).Jing-Tao Gao Juan Du Gui-Hui Wu Yi Pei Meng-Qiu Gao Leonardo Martinez Lin Fan Wei Chen Li Xie Yu Chen Hua Wang Long Jin Guo-Bao Li Pei-Lan Zong Yu Xiong Qian-Hong Wu Ming-Wu Li Xiao-Feng Yan Yan-Fang Miao Qing-Shan Cai Xin-Jie Li Da-Peng Bai Shu-Jun Geng Guo-Li Yang Pei-JunTang Yi Zeng Xiao-Hong Chen Tong-Xia Li Cui Cai Yun Zhou Ma Zhuo Jian-Yun Wang Wen-Long Guan Lin Xu Ji-Chan Shi Wei Shu Li-Li Cheng FeiTeng Yu-Jia Ning Shi-Heng Xie Yu-Xian Sun Li-Jie Zhang Yu-Hong Liu 2021Infectious Diseases of Poverty2021,10,2:11
5Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC.Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun 2022Cancer Communications2022,42,12:8

7Sedimentary Evolution and Transgressions of the Western Subei Basin in Eastern China since the Late Pliocene显示文摘Sedimentary sequences in the Subei Basin are complex and have been affected by interactions between the ocean and rivers since the Late Pliocene, including the Yellow River, Huaihe River, and the Yangtze River. This sedimentary evolution, in particular the timing of Pleistocene transgressions, has long been a matter of controversy owing to the lack of precise chronological evidence. The aim of this study is to explore the evolution of the sedimentary environment throughout the past 3.00 Ma in this region on the basis of a comprehensive analysis of particle size and foraminifera and ostracods collected in the TZK9 core from the Subei Basin combined with geochronological studies of magnetostratigraphy, AMS^(14)C and optically stimulated luminescence(OSL). The results show that fluvial facies in the sedimentary environment from 3.00 to 1.01 Ma. There were fluvial facies and reflects six sea-level high stands from 1.01 to 0.25 Ma. The study area was affected by four large-scale transgressions since 0.25 Ma. The four marine sedimentary layers known as DU7(buried at 48–52 m), DU5(buried at 35–41 m), DU3(buried at 16–23 m), and DU1(buried at 2–4 m) are recorded in the MIS7(210–250 ka), MIS5, MIS3, and Holocene, respectively. The magnitude of the DU5 transgression was identical to that of the DU3 transgression, both were larger than the DU7 transgression, and the DU1 transgression was the weakest. The variation of transgression strength reflects the influence of global changes in sea level, tectonic subsidence, shell ridges, and sand dams. In the TZK9 core, we found evidence of seven sea-level high stands from the Early–Middle Pleistocene, and the first one caused by regional rapid subsidence and could be traced back to 0.83-0.84 Ma. The sea-level high stands and the age of the first one recorded above was different from other cores in eastern China, this was caused by the lack of absolute age control and the differences in paleotopography during this period. This study reconstructs sedimentary evolution, determines the transgression and its age, establishes the chronology since the Late Pliocene, and provides a scientific framework for further paleoenvironmental and tectonic studies. The results of this study highlight the important role that local tectonics and global sea level play in the sedimentary evolution and transgressions that have occurred in the western Subei Basin.CHENG Yu LI Xiangqian SHU Junwu BAI Shibiao ZHAO Zengyu ZHANG Xiangyun GUO Gang ZHANG Ping LIN Jingxing 2019Acta Geologica Sinica(English Edition)2019,93,1:7
8Pyrroloquinoline quinone promotes mitochondrial biogenesis in rotenone-induced Parkinson’s disease model via AMPK activation显示文摘Mitochondrial dysfunction is considered to be one of the important pathogenesis in Parkinson’s disease (PD). We previously showed that pyrroloquinoline quinone (PQQ) could protect SH-SY5Y cells and dopaminergic neurons from cytotoxicity and prevent mitochondrial dysfunction in rotenone-induced PD models. In the present study we investigated the mechanisms underlying the protective effects of PQQ in a mouse PD model, which was established by intraperitoneal injection of rotenone (3 mg·kg^(−1)·d^(−1), ip) for 3 weeks. Meanwhile the mice were treated with PQQ (0.8, 4, 20 mg·kg^(−1)·d^(−1), ip) right after rotenone injection for 3 weeks. We showed that PQQ treatment dose-dependently alleviated the locomotor deficits and nigral dopaminergic neuron loss in PD mice. Furthermore, PQQ treatment significantly diminished the reduction of mitochondria number and their pathological change in the midbrain. PQQ dose-dependently blocked rotenone-caused reduction in the expression of PGC-1α and TFAM, two key activators of mitochondrial gene transcription, in the midbrain. In rotenone-injured human neuroblastoma SH-SY5Y cells, PTMScan Direct analysis revealed that treatment with PQQ (100 μM) differentially regulated protein phosphorylation;the differentially expressed phosphorylated proteins included the signaling pathways related with adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK) pathway. We conducted Western blot analysis and confirmed that AMPK was activated by PQQ both in PD mice and in rotenone-injured SH-SY5Y cells. Pretreatment with AMPK inhibitor dorsomorphin (4 μM) significantly attenuated the protective effect and mitochondrial biogenesis by PQQ treatment in rotenone-injured SH-SY5Y cells. Taken together, PQQ promotes mitochondrial biogenesis in rotenone-injured mice and SH-SY5Y cells via activation of AMPK signaling pathway.Qiong Cheng Juan Chen Hui Guo Jin-li Lu Jing Zhou Xin-yu Guo Yue Shi Yu Zhang Shu Yu Qi Zhang Fei Ding 2021Acta Pharmacologica Sinica2021,42,5:6
9The Achyranthes bidentata polypeptide k fraction enhances neuronal growth in vitro and promotes peripheral nerve regeneration after crush injury in vivo显示文摘We have previously shown that Achyranthes bidentata polypeptides(ABPP), isolated from Achyranthes bidentata Blume(a medicinal herb), exhibit neurotrophic and neuroprotective effects on the nervous system. To identify the major active component of ABPP, and thus optimize the use of ABPP, we used reverse-phase high performance liquid chromatography to separate ABPP. We obtained 12 fractions, among which the fraction of ABPPk demonstrated the strongest neuroactivity. Immunocytochemistry and western blot analysis showed that ABPPk promoted neurite growth in cultured dorsal root ganglion explant and dorsal root ganglion neurons, which might be associated with activation of Erk1/2. A combination of behavioral tests, electrophysiological assessment, and histomorphometric analysis indicated that ABPPk enhanced nerve regeneration and function restoration in a mouse model of crushed sciatic nerve. All the results suggest that ABPPk, as the key component of ABPP, can be used for peripheral nerve repair to yield better outcomes than ABPP.Qiong Cheng Chunyi Jiang Caiping Wang Shu Yu Qi Zhang Xiaosong Gu Fei Ding 2014Neural Regeneration Research2014,9,24:5
10The Adverse Effect of the 2-1-1 Regimen for Rabies PEP in Preschool Children显示文摘Post-exposure prophylaxis(PEP) has proved to be the most important measure for rabies prevention and control. There is little information regarding adverse reactions to the Essen and 2-1-1 regimens in preschool children(aged 0-6). We reexamined the outcomes of 1,109 preschool children who were vaccinated using SPEEDA under the Essen regimen between January 2011 and December 2012 and 1,267 preschool children under the 2-1-1 regimen between January 2013 and December 2014. We find that, in preschool children, the febrile reaction after the first 2-dose injection in the 2-1-1 regimen was significantly higher than that induced by the first 1-dose in the Essen procedure. Thus, we recommend that the Essen regimen should still be used for rabies PEP in preschool children.LIU Shu Qing TAO Xiao Yan YU Peng Cheng JIN Chun Qiu YU Hong Jie CHEN Mei Shun ZHU Wu Yang 2017Biomedical and Environmental Sciences2017,30,5:5

12The development of a sensitive fluorescent protein-based transcript reporter for high throughput screening of negative modulators of lncRNAs显示文摘While the human genome is pervasively transcribed,<2%of the human genome is transcribed into protein-coding mRNAs,leaving most of the transcripts as noncoding RNAs,such as microRNAs and long-noncoding RNAs(lncRNAs),which are critical components of epigenetic regulation.lncRNAs are emerging as critical regulators of gene expression and genomic stability.However,it remains largely unknown about how lncRNAs are regulated.Here,we develop a highly sensitive and dynamic reporter that allows us to identify and/or monitor negative modulators of lncRNA transcript levels in a high throughput fashion.Specifically,we engineer a fluorescent fusion protein by fusing three copies of the PEST destruction domain of mouse ornithine decarboxylase(MODC)to the C-terminal end of the codon-optimized bilirubin-inducible fluorescent protein,designated as dBiFP,and show that the dBiFP protein is highly destabilized,compared with the commonly-used eGFP protein.We further demonstrate that the dBiFP signal is effectively down-regulated when the dBiFP and mouse lncRNA H19 chimeric transcript is silenced by mouse H19-specific siRNAs.Therefore,our results strongly suggest that the dBiFP fusion protein may serve as a sensitive and dynamic transcript reporter to monitor the inhibition of lncRNAs by microRNAs,synthetic regulatory RNA molecules,RNA binding proteins,and/or small molecule inhibitors so that novel and efficacious inhibitors targeting the epigenetic circuit can be discovered to treat human diseases such as cancer and other chronic disorders.Zongyue Zeng Bo Huang Shifeng Huang Ruyi Zhang Shujuan Yan Xinyi Yu Yi Shu Chen Zhao Jiayan Lei Wenwen Zhang Chao Yang Ke Wu Ying Wu Liping An Xiaojuan Ji Cheng Gong Chengfu Yuan Linghuan Zhang Wei Liu Yixiao Feng Bo Zhang Zhengyu Dai Yi Shen Xi Wang Wenping Luo Rex C.Haydon Hue H.Luu Lan Zhou Russell R.Reid Tong-Chuan He Xingye Wu 2018Genes & Diseases2018,5,1:4
13Association of the ADIPOQ Rs2241766 and Rs266729 Polymorphisms with Metabolic Syndrome in the Chinese Population:A Meta-analysis显示文摘Objective This meta-analysis was performed to summarize the association of the ADIPOQ rs2241766 and rs266729 polymorphisms with metabolic syndrome(MS) in the Chinese population.Methods We searched for articles in MEDLINE via PubM ed,EMBASE,HuG E Navigator,CNKI,and Wanfang databases and calculated odds ratios(ORs) with 95% confidence intervals(CIs) to determine the strength of associations in fixed-or random-effects models.Results We included 21 articles in the meta-analysis:17 reports of ADIPOQ rs2241766 with 3628 cases and 3000 controls and 8 of rs266729 with 2021 cases and 2226 controls.We found an increased risk of MS with the ADIPOQ rs2241766 polymorphism in some genetic models(allele model:OR=1.12,95% CI:1.03-1.21;dominant model:OR=1.15,95% CI:1.04-1.28;homozygote model:OR=1.22,95% CI:1.00-1.49) but no association with the ADIPOQ rs266729 polymorphism(allele model:OR=0.98,95% CI:0.82-1.17;dominant model:OR=0.90,95% CI:0.79-1.02;recessive model:OR=1.09,95% CI:0.85-1.39;homozygote model:OR=1.03,95% CI:0.80-1.33).Conclusion The results of this meta-analysis suggest an association between the ADIPOQ rs2241766 polymorphism and MS in the Chinese population.G allele of ADIPOQ rs2241766 increases the risk of MS.Better designed studies with different ethnic populations and larger sample sizes are needed for assessing the relationship between ADIPOQ rs2241766 and rs266729 polymorphisms and MS in the future.ZHOU Jun Mei ZHANG Ming WANG Shu WANG Bing Yuan HAN Cheng Yi REN Yong Cheng ZHANG Lu ZHANG Hong Yan YANG Xiang Yu ZHAO Yang HU Dong Sheng 2016Biomedical and Environmental Sciences2016,29,7:3
14Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li 2014Biomedical and Environmental Sciences2014,27,5:3
15Stannous oxalate as a novel catalyst for the synthesis of polytrimethylene terephthalate显示文摘Stannous oxalate was prepared efficiently and characterized by XRD and FT-IR. It exhibited higher catalytic activity and had profitable effect than tetrabutyl titanate and stannous octoate for the synthesis of polytrimethylene terephthalate (PTT) via esterification-route. Over this catalyst, the degree of esterification of pure terephthalic acid was up to 94.4% at 260°C after 1.5 h, while the intrinsic viscosity and content of terminal carboxyl groups of the corresponding PTT polyester, polymerized at 260°C, 60 Pa for 2 h, was 0.8950 dL/g and 15 mol/t, respectively. Stannous oxalate was a promising catalyst for the synthesis of PTT polyester.Yu Rong Ren Shu Yong Jia Shou Cai Zhang Chun Ling Liu Yun Cheng Cui 2007Chinese Chemical Letters2007,18,7:3
16Particulate matter pollution in Kunshan High-Tech zone: Source apportionment with trace elements, plume evolution and its monitoring显示文摘Particulate matter(PM) in the Kunshan High-Tech zone is studied during a three-month campaign. PM and trace elements are measured by the online pollution monitoring, forecastwarning and source term retrieval system AS3. Hourly measured concentrations of PM_(10), PM_(2.5) and 16 trace elements in the PM_(2.5) section(Ca, Pb, Cu, Cl, V, Cr, Fe, Ti, Mn, Ni, Zn, Ga, As, Se, Sr, Ba)are focused. Source apportionment of trace elements by Positive Matrix Factorization modeling indicates that there are five major sources, including dust, industrial processing, traffic,combustion, and sea salt with contribution rate of 23.68%, 21.66%, 14.30%, 22.03%, and 6.89%,respectively. Prediction of plume dispersion from concrete plant and traffic emissions shows that PM_(10) pollution of concrete plant is three orders of magnitude more than that of the traffic. The influence range can extend to more than 3 km in 1 hr. Because the footprint of the industrial plumes is constantly moving according to the local meteorological conditions, the fixed monitoring sites scattered in a few hundred meters haven't captured the heaviest pollution plume at the local scale of a few km^2. As a more intensive monitoring network is not operationally possible, the use of online modeling gives accurate and quantitative information of plume location, which increases the spatial pollution monitoring capacity and improves the understanding of measurement data. These results indicate that the development of the AS3 system, which combines monitoring equipment and air pollution modeling systems, is beneficial to the real-time pollution monitoring in the industrial zone.Suwei Zhang Qijie Zhang Armand Albergel Didier Buty Liangmin Yu Haiting Wang Wuxia Bi Peng Cheng Fu Chen Jun Fang Ruirui Hou Xudong Luan Changgan Shu Jingjing Su 2018Journal of Environmental Sciences2018,30,9:3
17Accumulated Clinical Experiences from Successful Treatment of 1377 Severe and Critically Ill COVID-19 Cases显示文摘Summary:In late December 2019,COVID-19 was firstly recognized in Wuhan,China and spread rapidly to all of the provinces of China.The West Campus of Wuhan Union Hospital,the designated hospital to admit and treat the severe and critically ill COVID-19 cases,has treated a large number of such patients with great success and obtained lots of valuable experiences based on the Chinese guideline(V7.0).To standardize and share the treatment procedures of severe and critically ill cases,Wuhan Union Hospital has established a working group and formulated an operational recommendation,including the monitoring,early warning indicators,and several treatment principles for severe and critically ill cases.The treatment experiences may provide some constructive suggestions for treating the severe and critically ill COVID-19 cases all over the world.Yong GAO Hai-bo QIU Shu ZHOU Zhen-ning WANG Jian-chu ZHANG Zheng-liang ZHANG Zhao-xin QIAN Hong-bo WANG Shi-huan YU Yi-feng LUO Ya dan WANG Zhuang LIU Wei-ci WANG Ming JIA Li-ming ZHANG Yu ZHANG Yang JIN Yong ZHANG Yong LIU Zi-hua ZHOU Ying SU Hui-qing LI Wei-min XIAO Kai HUANG Ping HE Gang LI Zhao-hui FU Shi LIU Neng xing LIN Fan-jun CHENG 2020Current Medical Science2020,40,4:2
18Mesomorphous structure change by tail chain number in ionic liquid crystalline complexes of linear polymer and amphiphiles显示文摘Three polymer-amphiphile complexes were prepared by combining poly(allylamine hydrochloride)(PAH) with the potassium salt of mono-,di-,and trisubstituted benzoic acid dendrons(4-octyloxybenzoic acid,3,5-dioctyloxybenzoic acid,and 3,4,5- trioctyloxybenzoic acid).The solid structure and properties were monitored with FT-IR,XRD,TG,DSC,and polarized optical microscope(POM).Difference in the tail chain number of the dendritic amphiphile induced two different mesomorphous structures: lamella for the mono-,disubstituted dendron containing complexes and hexagonal column for the trisubstituted dendron containing complexes.These corresponded to the ionic thermotropic liquid crystal SmA andΦ_h phases,respectively.This finding is significant for design of functional nanostructures based on the ionic complexation of polymers and amphiphiles.Zhi Yu Cheng Bi Ye Ren Shu Ying He Xin Xing Liu Zhen Tong 2011Chinese Chemical Letters2011,22,11:2

20Investigation of Anxiety, Depression, Stress and Related Factors in the Primary Caregivers of Inpatients with Cancer显示文摘Objectives To explore the anxiety,depression,stress and related factors in the primary caregivers of inpatients with cancer.Methods A total of 235 selected caregivers of inpatients with cancer were included as the research subjects,and the Depression-Anxiety-Stress Self-Rating Scale 21(DASS-21)was used to evaluate their depression,anxiety and stress.The data were statistically analyzed using SPSS 25.0 software.Results The study showed that the caregivers of cancer patients had different levels of depression,anxiety and stress,but all rates were above the normal range,with 51.7%,56.0%and 34.9%of subjects respectively reporting these conditions.In addition,the above indicators were correlated with the caregivers’gender,age,relationship with the cancer patients,the family’s economic status,religious belief and duration of caregiving:being female(T-Statistic=-2.061,P=0.040)and having a low income(F=2.627,P=0.035)were positively correlated with the caregivers’stress level.Having a low income(F=2.804,P=0.027)was also positively correlated with the depression scores.When the caregivers were the patient's parents,they had higher levels of anxiety(F=2.429,P=0.036)than caregivers in other relationships.The results of a linear correlation analysis showed that the depression of caregivers was negatively correlated with the family’s economic status(r value=-0.244,P<0.01)and positively correlated with the duration of caregiving(r=0.138,P<0.05).The anxiety score was positively correlated with the caregivers’age(r=0.141,P<0.05)and duration of caregiving(R=0.132,P<0.05),but negatively correlated with the family’s economic status(r=-0.187,P<0.01).The stress level was positively correlated with the caregivers’gender(r=0.137,P<0.05),age(r=0.210,P<0.01),duration of caregiving(r=0.171,P<0.01)and current job status(r=0.165,P<0.05),but negatively correlated with the family’s economic status(r=-0.202,P<0.01).The results of a multiple stepwise regression showed that age and religious belief were significant predictors of stress,while the family’s economic status was a significant predictor of depression,and age was a significant predictor of anxiety.Conclusion The caregivers of hospitalized cancer patients showed varying degrees of anxiety,depression and stress,according the psychological assessments;the provision or interventions might be helpful for these individuals.Hong Hong Xu Ruo Tong Xue Yi Cheng Yu Jie Zhang Jie Rao Mei Liu Shi Ying Yu Ling Xiang Liu Yi Qian Liu Yong Qian Shu Liu Qing Yang Han Ping Shi 2020Journal of Nutritional Oncology2020,5,4:2
