1A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161
2Multimodality treatment in hepatocellular carcinoma patients with tumor thrombi in portal vein显示文摘AIM To compare the therapeutic effect andsignificances of multimodality treatment forhepatocellular carcinoma (HCC) with tumorthrombi in portal vein (PVTT).METHODS HCC patients (n = 147) with tumortrombi in the main portal vein or the first branchof portal vein were divided into four groups bythe several therapeutic methods. There wereconservative treatment group in 18 out ofpatients (group A); and hepatic artery ligation(HAL) and/or hepatic artery infusion (HAl)group in 18 patients (group B), in whompostoberative chemoembolization was doneperiodically; group of removal of HCC with PVTTin 79 (group C) and group of transcatheterhepatic arterial chemoembolization (TACE) orHAl and/or portal vein infusion (PVI) afteroperation in 32 (group D).RESULTS The median survival period was 12months in our series and the 1-, 3-, and 5-yearsurvival rates were 44.3%, 24.5% and 15.2%,respectively. The median survival times were 2,5, 12 and 16 months in group A, B, C and D,respectively. The 1-, 3- and 5-year survival rateswere 5.6%, 0% and 0% in group A; 22.2%,5.6% and 0% in group B; 53.9%, 26.9% and16.6% in group C; 79.3%, 38.9% and 26.8% ingroup D, respectively. Significant differenceappeared in the survival rates among the groups(P<0.05).CONCLUSION Hepatic resection with removalof tumor thrombi and HCC should increase thecurative effects and be encouraged for theprolongation of life span and quality of life forHCC patients with PVTT, whereas the besttherapeutic method for HCC with PVTT is withregional hepatic chemotherapy orchemoemblization after hepatic resection withremoval of tumor thrombi.Jia Fan Zhi Quan Wu Zhao You Tang Jian Zhou Shuang Jian Qiu Zeng Chen Ma Xin Da Zhou Sheng Long Ye Liver Cancer Institute, Zhongshan Hospital, Fudan University Medical Center (Former Shanghai University), 136 Yixueyuan Road, Shanghai 200032, China 2001World Journal of Gastroenterology2001,7,1:80
3Morphological and functional changes of mitochondria in apoptotic esophageal carcinoma cells induced by arsenic trioxide显示文摘AIM:To demonstrate that mitochondrial morphological andfunctional changes are an important intermediate link in thecourse of apoptosis in esophageal carcinoma calls inducedby As_2O_3.METHODS:The esophageal carcinoma call line SHEEC1,established in our laboratory,was cultured in 199 growthmedium,supplemented with 100mL·L^(-1)calf serum and3 mol·L^(-1)As_2O_3(the same below).After 2,4,6,12,24 hof drug adding,the SHEECl calls were collected for light-and electron-microscopic examination.The mitochondriawere labeled by Rhodamine fluorescence probe and thefluorescence intensity of the mitochondria was measured byflow cytorneter and cytofluorimetric analysis.Further,themitochondrial transmembrane potential(MTP,ΔΨm)change was also calculated.RESULTS:The mitochondrial morphological change afteradding As_2O_3 could be divided into three stages.In theearly-stage(2-6h)after adding As203,an adaptiveproliferation of mitochondria appeared;in the mid-stage(6-12 h)a degenerative change was observed;and in the late-stage(12-24 h)the mitochondria swelled with outermembrane broken down and then calls death with apoptoticchanges of nucleus.The functional change of themitochondria indicated by fluorescent intensity,whichreflected the MTP status of mitochondria,was in accordancewith morphological change of the mitochondria.Thefluorescent intensity increased at early-stage,decUned inmid-stage and decreased to the lowest in the late-stage.24h after As_2O_3 adding,the cell nucleus showed typicalapoptotic changes.CONCLUSION:Under the inducement of As_2O_3,the earlyapoptotic changes of SHEEC1 cells ware the apparentmorphological and functional changes of mitochondria,afterwards the nucleus changes followed.It is consideredthat changes of mitochondria are an important intermediatelink in the course of apoptosis of esophageal carcinoma cells induced by As_2O_3.Zhong-Ying Shen Jian Shen Qiao-Shan Li Department of Pathology,Medical College of Shantou University,Shantou 515031,Guandong Province,China Cai-Yun Chen Central Lab.Medical College of Shantou University Jiong-Yu Chen Central Lab.of Tumor Hospital,Medical College of Shantou University Yi Zeng Institute of Virology,Chinese Academy of Preventive Medicine,Beijing 100052,China 2002World Journal of Gastroenterology2002,8,1:35
4Characteristics of land surface thermal-hydrologic processes for different regions over North China during prevailing summer monsoon period显示文摘The observation stations of Northern China are divided into three regions:the arid Northwest China,the Loess Plateau,and the cool Northeast China.The consistencies,differences,and associated mechanisms of land surface thermal-hydrologic processes among the three regions were studied based on the normalization of major variables of land surface thermal-hydrologic processes,using data collected during prevailing summer monsoon period(July and August,2008).It is shown that differences of surface thermal-hydrologic processes are remarkable among the three regions because of different impacts of summer monsoon.Especially their soil wet layers occur at different depths,and the average albedo and its diurnal variations are distinctly different.Surface net short-wave radiation in the Loess Plateau is close to that in the cool Northeast China,but its surface net long-wave radiation is close to that in the arid Northwest China.And the ratio of net radiation to global solar radiation in the cool Northeast China is higher than the other two regions,though its temperature is lower.There are obvious regional differences in the ratios of surface sensible and latent heat fluxes to net radiation for the three regions because of distinct contribution of sensible and latent heat fluxesto land surface energy balance.The three regions are markedly different in the ratio of water vapor flux to pan evaporation,but they are consistent in the ratio of water vapor flux to precipitation.These results not only indicate different influences of climate and environmental factors on land surface thermal-hydrologic processes in the three regions,but also show that summer monsoon is important in the formation and variation of the pattern of land surface thermal-hydrologic processes.ZHANG Qiang ZENG Jian ZHANG LiYang 2012Science China Earth Sciences2012,55,11:28

6Clinicopathologic characteristics and prognosis of gastroenteropancreatic neuroendocrine neoplasms: a multicenter study in South China显示文摘Background: Gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs) are a heterogeneous group of rare tumors. Many issues in terms of epidemiologic features, pathogenesis, and treatment of GEP-NENs are still under discussion. Our study aimed to analyze the clinicopathologic characteristics and prognosis of Chinese patients with GEP-NENs.Methods: Complete clinicopathologic data and survival information of 1183 patients with GEP-NENs treated between 2005 and 2015 were collected from five medical centers in Guangdong Province, China. Patient survival was estimated using the Kaplan–Meier method and analyzed using the log-rank test; prognostic factors were analyzed using the Cox proportional hazards model.Results: The most common tumor location was the rectum(37.4%), followed by the pancreas(28.1%), stomach(20.7%), small intestine(7.2%), appendix(3.4%), and colon(3.3%). After initial definitive diagnosis, 1016(85.9%) patients underwent surgery. The 1-, 3-, and 5-year overall survival(OS) rates for the entire cohort were 87.9%, 78.5%, and 72.8%, respectively. The 3-year OS rates of patients with G1, G2, and G3 tumors were 93.1%, 82.7%, and 43.1%, respectively(P < 0.001). The 3-year OS rates of patients with stage I, II, III, and IV tumors were 96.0%, 87.3%, 64.0%, and 46.8%, respectively(P < 0.001). Patients with distant metastasis who underwent palliative surgery had a longer survival than those who did not(P = 0.003). Similar survival benefits of palliative surgery were observed in patients with neuroendocrine tumor(P y, M category, and sur= 0.031) or neuroendocrine carcinoma(P gery were found to be independent prog= 0.046). In multivariate analysis, age, grade, N categornostic factors.Conclusions: Patients with GEP-NENs who are women, younger than 50 years old, have smaller tumor size, have lower tumor grade, have lower T/N/M category, and who undergo surgery can have potentially longer survival time. Our data showed that surgery can improve the prognosis of GEP-NEN patients with distant metastasis. However, randomized controlled trials need to be conducted to establish the optimal criteria for selecting patients to undergo surgery.Cheng Fang Wei Wang Yu Zhang Xingyu Feng Jian Sun Yujie Zeng Ye Chen Yong Li Minhu Chen Zhiwei Zhou Jie Chen 2017Chinese Journal of Cancer2017,36,10:23
7Telomere and telomerase in the initial stage of immortalization of esophageal epithelial cell显示文摘AIM: To search for the biomarker of cellular immortalization,the telomere length, telomerase activity and its subunits incultured epithelial cells of human fetal esophagus in theprocess of immortalization.METHODS: The transgenic cell line of human fetalesophageal epithelium (SHEE) was established with E6 E7genes of bt man papillomavirus (HPV) type 18 in ourlaboratory. Morphological phenotype of cultured SHEE cellsfrom the 6th to 30th passages, was examined by phasecontrast microscopy, the telomere length was assayed bySouthern blot method, and the activity of telomerase wasanalyzed by telomeric repeat amplification protocol (TRAP).Expressions of subunits of telomerase, hTR and hTERT,were assessed by RT-PCR. DNA content in cell cycle wasdetected by flow cytometry. The cell apoptosis wasexamined by electron microscopy (EM) and TUNEL label.RESULTS: SHEE cells from the 6 th to 10 th passagesshowed cellular proliferation with a good differentiation.From the 12 th to the 16 th passages, many senescent andapoptotic cells appeared, and the telomere length sharplyshortened from 23 kb to 17 kb without expression of hTERTand telornerase activity. At the 20 th passage, SHEE cellsovercame the senescence and apoptosis and restored theirproliferative activity with expression of telomerase andhTERT at low levels, but the telomere length shortenedcontinuously to the lowest of 3 kb. After the 30 th passagecells proliferation was restored by increment of cells at S andG2M phase in the cell cycle end telomerase activity expressedat high levels and with maintenance of telomere length.CONCLUSION: At the early stage of SHEE cells, telomeresare shortened without expression of telomerase and hTERTcausing cellular senescence and cell death. From the 20 thto the 30 th passages, the activation of telomerase andmaintenance of telomere length show a progressive processfor immortalization of esophageal epithelial cells. Theexpression of telomerase may constitute a biomarker fordetection of immortalization of cells.Zhong-Ying Shen Li-Yan Xu Wei-Jia Cai Min-Hua Chen Jian Shen,Department of Tumor Pathology,Medical College of Shantou University,Shantou 515031,Guangdong Province,China En-Min Li,Department of Biochemistry and Molecular Biology,Medical College of Shantou University,Shantou 515031,Guangdong Province,China Yi Zeng,Institute of Virology,Chinese Academy of Preventive Medicine,Beijing 100052,China 2002World Journal of Gastroenterology2002,8,2:21

11Sparse SAR imaging based on L_(1/2) regularization显示文摘In this paper,a novel method for synthetic aperture radar(SAR)imaging is proposed.The approach is based on L1/2 regularization to reconstruct the scattering field,which optimizes a quadratic error term of the SAR observation process subject to the interested scene sparsity.Compared to the conventional SAR imaging technique,the new method implements SAR imaging effectively at much lower sampling rate than the Nyquist rate,and produces high-quality images with reduced sidelobes and increased resolution.Also,over the prevalent greedy pursuit and L1 regularization based SAR imaging methods,there are remarkable performance improvements of the new method.On one hand,the new method significantly reduces the number of measurements needed for reconstruction,as supported by a phase transition diagram study.On the other hand,the new method is more robust to the observation noise.These fundamental properties of the new method are supported and demonstrated both by simulations and real SAR data experiments.ZENG JinShan FANG Jian XU ZongBen 2012Science China(Information Sciences)2012,55,8:18
12Quality of life after three kinds of esophagectomy for cancer显示文摘AIM:To evaluate quality of life(QOL) following Ivor Lewis,left transthoracic,and combined thoracoscopic/laparoscopic esophagectomy in patients with esophageal cancer.METHODS:Ninety patients with esophageal cancer were assigned to Ivor Lewis(n = 30),combined thoracoscopic/laparoscopic(n = 30),and left transthoracic(n = 30) esophagectomy groups.The QOL-core 30 questionnaire and the supplemental QOL-esophageal module 18 questionnaire for patients with esophageal cancer,both developed by the European Organization for Research and Treatment of Cancer,were used to evaluate patients' QOL from 1 wk before to 24 wk after surgery.RESULTS:A total of 324 questionnaires were collected from 90 patients;36 postoperative questionnaires were not completed because patients could not be contacted for follow-up visits.QOL declined markedly in all patients at 1 wk postoperatively:preoperative and 1-wk postoperative global QOL scores in the Ivor Lewis,combined thoracoscopic/laparoscopic,and left transthoracic groups were 80.8 ± 9.3 vs 32.0 ± 16.1(P < 0.001),81.1 ± 9.0 vs 53.3 ± 11.5(P < 0.001),and 83.6 ± 11.2 vs 46.4 ± 11.3(P < 0.001),respectively.Thereafter,QOL recovered gradually in all patients.Patients who underwent Ivor Lewis esophagectomy showed the most pronounced decline in QOL;global scores were lower in this group than in the combined thoracoscopic/laparoscopic(P < 0.001) and left transthoracic(P < 0.001) groups at 1 wk postoperatively and was not restored to the preoperative level at 24 wk postoperatively.QOL declined least in patients undergoing combined thoracoscopic/laparoscopic esophagectomy,and most indices had recovered to preoperative levels at 24 wk postoperatively.In the Ivor Lewis and combined thoracoscopic/laparoscopic groups,pain and physical function scores were 78.9 ± 18.5 vs 57.8 ± 19.9(P < 0.001) and 59.3 ± 16.1 vs 70.2 ± 19.2(P = 0.02),respectively,at 1 wk postoperatively and 26.1 ± 28.6 vs 9.5 ± 15.6(P = 0.007) and 88.4 ± 10.5 vs 95.8 ± 7.3(P = 0.003),respectively,at 24 wk postoperatively.Scores in the left transthoracic esophagectomy group fell between those of the other two groups.CONCLUSION:Compared with Ivor Lewis and left transthoracic esophagectomies,combined thoracoscopic/laparoscopic esophagectomy enables higher postoperative QOL,making it a preferable surgical approach for esophageal cancer.Jian Zeng Jin-Shi Liu 2012World Journal of Gastroenterology2012,18,36:18
13Gambogic acid induces mitochondria-dependent apoptosis by modulation of Bcl-2 and Bax in mantle cell lymphoma JeKo-1 cells显示文摘Aim: To study the mechanisms in gambogic acid (GA) -induced JeKo-1 human Mantle Cell Lymphoma cell apoptosis in vitro. Methods: The proliferation of GA-treated JeKo-1 cells was measured by CCK-8 assay and Ki-67 immunocytochemical detection. Apoptosis, cell cycle and mitochondrial membrane potential were measured by flow cytometric analysis. Caspase-3,-8 and -9 were detected by colorimetric assay. Bcl-2 and Bax were analyzed by Western blotting. Results: GA inhibited cell growth in a time-and dose-dependent manner. GA induces apoptosis in JeKo-1 cells but not in normal bone marrow cells, which was involved in reducing the membrane potential of mitochondria, activating caspases-3, -8 and -9 and decreasing the ratio of Bcl-2 and Bax without cell cycle arresting. Conclusions: GA induced apoptosis in human MCL JeKo-1 cells by regulating Bcl-2/Bax and activating caspase-3, -8 and -9 via mitochondrial pathway without affecting cell cycle.Jingyan Xu Min Zhou Jian Ouyang Jing Wang Qiguo Zhang Yong Xu Yueyi Xu Qian Zhang Xihui Xu Hui Zeng 2013Chinese Journal of Cancer Research2013,25,2:18

20Time-depth conversion of transient electromagnetic method used in coal mines显示文摘Accuracy of time-depth conversion in data processing of transient electromagnetic prospecting always affects the accu- rate positioning of water bodies in coal mines. In order to improve the accuracy of time-depth conversion, we established a mathe- matical model of time-depth conversion for a transient electromagnetic method based on the theory of 'double smoke ring effect' of full space transient electromagnetic field transmission. Using a 3-layer as well as a 4-layer geo-electric model for roadway floors, we performed the time-depth conversion of theoretical curves of apparent resistance varying over time. In these curves, the depth corresponding to extreme value points is nearly the same as the depth of a geo-electric model. The position of water body deter- mined by our time-depth conversion method agrees well with the result of borehole drilling, indicating that the established time-depth conversion model can clearly improve the accuracy of spatial positioning of water bodies in coal mines.YU Jing-cun WANG Yang-zhou LIU Jian ZENG Xiao-bo 2008Journal of China University of Mining and Technology2008,18,4:15
