1The Chinese Society of Clinical Oncology(CSCO):clinical guidelines for the diagnosis and treatment of gastric cancer显示文摘China is one of the countries with the highest incidence of gastric cancer.There are differences in epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selection between gastric cancer patients from the Eastern and Western countries.Non-Chinese guidelines cannot specifically reflect the diagnosis and treatment characteristics for the Chinese gastric cancer patients.The Chinese Society of Clinical Oncology(CSCO)arranged for a panel of senior experts specializing in all sub-specialties of gastric cancer to compile,discuss,and revise the guidelines on the diagnosis and treatment of gastric cancer based on the findings of evidence-based medicine in China and abroad.By referring to the opinions of industry experts,taking into account of regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted experts’consensus judgement on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes.This guideline uses tables and is complemented by explanatory and descriptive notes covering the diagnosis,comprehensive treatment,and follow-up visits for gastric cancer.Feng-Hua Wang Lin Shen Jin Li Zhi-Wei Zhou Han Liang Xiao-Tian Zhang Lei Tang Yan Xin Jing Jin Yu-Jing Zhang Xiang-Lin Yuan Tian-Shu Liu Guo-Xin Li Qi Wu Hui-Mian Xu Jia-Fu Ji Yuan-Fang Li Xin Wang Shan Yu Hao Liu Wen-Long Guan Rui-Hua Xu 2019Cancer Communications2019,39,1:127
2The Chinese Society of Clinical Oncology(CSCO):Clinical guidelines for the diagnosis and treatment of gastric cancer,2021显示文摘There exist differences in the epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selections between gastric cancer patients from the Eastern and Western countries.The Chinese Society of Clinical Oncology(CSCO)has organized a panel of senior experts specializing in all sub-specialties of gastric cancer to compile a clinical guideline for the diagnosis and treatment of gastric cancer since 2016 and renews it annually.Taking into account regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted expert consensus judgment on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes in China.The 2021 CSCO Clinical Practice Guidelines for Gastric Cancer covers the diagnosis,treatment,follow-up,and screening of gastric cancer.Based on the 2020 version of the CSCO Chinese Gastric Cancer guidelines,this updated guideline integrates the results ofmajor clinical studies from China and overseas for the past year,focused on the inclusion of research data from the Chinese population for more personalized and clinically relevant recommendations.For the comprehensive treatment of non-metastatic gastric cancer,attentions were paid to neoadjuvant treatment.The value of perioperative chemotherapy is gradually becoming clearer and its recommendation level has been updated.For the comprehensive treatment of metastatic gastric cancer,recommendations for immunotherapy were included,and immune checkpoint inhibitors fromthird-line to the first-line of treatment for different patient groups with detailed notes are provided.Feng-Hua Wang Xiao-Tian Zhang Yuan-Fang Li Lei Tang Xiu-Juan Qu Jie-Er Ying Jun Zhang Ling-Yu Sun Rong-Bo Lin Hong Qiu Chang Wang Miao-Zhen Qiu Mu-Yan Cai QiWu Hao Liu Wen-Long Guan Ai-Ping Zhou Yu-Jing Zhang Tian-Shu Liu Feng Bi Xiang-Lin Yuan Sheng-Xiang Rao Yan Xin Wei-Qi Sheng Hui-Mian Xu Guo-Xin Li Jia-Fu Ji Zhi-Wei Zhou Han Liang Yan-Qiao Zhang Jing Jin Lin Shen Jin Li Rui-Hua Xu 2021Cancer Communications2021,41,8:97
3Evidence of crustal ‘channel flow’ in the eastern margin of Tibetan Plateau from MT measurements显示文摘Magnetotelluric (MT) survey has been carried out in the eastern margin of the Tibetan Plateau and its neighboring Shimian-Leshan area, Sichuan Province. Analysis of this MT data reveals that the electric structure of the Tibetan Plateau differ much from that of the Sichuan block. In general, the electric re-sistivity of crust beneath the Sichuan block in the east is larger than that of the eastern margin of the Tibetan Plateau in the west. The crust of the plateau is divided into upper, middle, and lower layers. The middle crust is a low resistivity layer with minimum down to 3―10 Ωm about 10―15 km thick. It pre-sumably contains partial melt and/or salt-bearing fluids with low viscosity, prone to deform and flow, producing a 'channel flow' under the southeastward squeeze of the eastern Tibetan Plateau. This low-resistivity layer makes the upper crust decoupled mechanically from the lower crust. In the brittle upper crust, faults are dominated by left-lateral strike-slip and thrust motions, leading to surface rising and shallow earthquakes. The low-resistivity layer also cut the Xianshuihe-Anninghe fault zone into two sections vertically. In this region, the thicknesses of upper, middle, and lower crust vary laterally, pro-ducing a transitional zone in the eastern margin of the Tibetan Plateau characterized by thicker crust and higher elevation in the west and thinner crust and lower elevation in the east.ZHAO GuoZe CHEN XiaoBin WANG LiFeng WANG JiJun TANG Ji WAN ZhanSheng ZHANG JiHong ZHAN Yan XIAO QiBin 2008Chinese Science Bulletin2008,53,12:57
4Chinese expert consensus on cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal malignancies显示文摘Locoregional spread of abdominopelvic malignant tumors frequently results in peritoneal carcinomatosis(PC). The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery(CRS) + hyperthermic intraperitoneal chemotherapy(HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases Ⅰ, Ⅱ and Ⅲ clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.Yan Li Yun-Feng Zhou Han Liang Hua-Qing Wang Ji-Hui Hao Zheng-Gang Zhu De-Seng Wan Lun-Xiu Qin Shu-Zhong Cui Jia-Fu Ji Hui-Mian Xu Shao-Zhong Wei Hong-Bin Xu Tao Suo Shu-Jun Yang Cong-Hua Xie Xiao-Jun Yang Guo-Liang Yang 2016World Journal of Gastroenterology2016,22,30:58

6Ultrasonography guided percutaneous radiofrequency ablation for hepatic cavernous hemangioma显示文摘AIM: Hepatic cavernous hemangioma (HCH) is the mostcommon benign tumor of the liver and its management isstill controversial. Recent successin situ radiofrequencyablation of hepatic malignancies has led us to consider usingthis technique in patients with HCH. This study was to assessthe efficacy, safety, and complications of percutaneousradiofrequency ablation (PRFA) under ultrasonographyguidance in patients with HCH.METHODS: Twelve patients (four men and eight women,age ranged 33-56 years, mean age was 41.7 years) with 15hepatic cavernous hemangiomas (2.5 cm to 9.5 cm) weretreated using the RF-2000 generator and 10-needle LeVeenelectrode percutaneously guided by B-ultrasound. Lesionslarger than 3 cm were treated by multiple overlappingablations that encompass the entire lesion as well as a rimof normal liver tissue (approximately 0.5 cm).RESULTS: All the patients who received PRFA therapy hadno severe pain, bleeding or bile leakage during and afterthe procedures. Nine to 34 months′ follow-up (mean, 21months) by ultrasound and/or spiral CT scan demonstratedthat the ablated lesions in this group were shrunk remarkably,and the shrunken range was 38-79 % (mean, 67 % per 21months). The contrast enhancement was disappeared withinthe tumor or at its periphery in all cases on spiral CT scansobtained 3 to 6 months after treatment.CONCLUSION: The results of this study suggest that PRFAtherapy is a mini-invasive, simple, safe, and effective methodfor the treatment of selected patients with HCH.Yan Cui Li-Yan Zhou Man-Ku Dong Ping Wang Min Ji Xiao-Ou Li Chang-Wei Chen Zi-Pei Liu Yong-Jie Xu Hong-Wen Zhang Department of Hepatobiliary Surgery,Beijing 306 Hospital,Chaoyang District,Beijing 100101,China 2003World Journal of Gastroenterology2003,9,9:43

8Deep structure beneath the southwestern section of the Longmenshan fault zone and seimogenetic context of the 4.20 Lushan M_S7.0 earthquake显示文摘Magnetotelluric measurements were carried out along two profiles across the middle and southwestern sections of the Longmenshan fault zone(LMSf)from 2009 to 2011,after the 2008 Wenchuan MW7.9 earthquake.The former profile crosses the Wenchuan event epicenter and the latter one crosses 2013 Lushan MS7.0 event epicenter.The data were analyzed using advanced processing techniques,including phase tensor and two-dimensional inversion methods,in order to obtain reliable 2-D profiles of the electrical structure in the vicinity of the two earthquakes.A comparison of the two profiles indicates both similarities and differences in the deep crustal structure of the LMSf.West of the southwestern section,a crustal high conductivity layer(HCL)is present at about 10 km depth below the Songpan-Garzêblock;this is about 10 km shallower than that under the middle section of the LMSf.A high resistivity body(HRB)is observed beneath the southwestern section,extending from the near surface to the top of upper mantle.It has a smaller size than the HRB observed below the middle section.In the middle section,there is a local area of decreased resistivity within the HRB but there is absence of this area.The 2013 Lushan earthquake occurred close to the eastern boundary of HRB and the Shuangshi-Dachuan fault,of which the seismogenic context has both common and different features in comparison with the 2008 Wenchuan event.On a large scale,the 2013 Lushan earthquake is associated with the HCL and deformation in the crust including HCL of the eastern Tibetan Plateau.In order to assess seismic risk,it is important to consider both the stress state and the detailed crustal structure in different parts of the LMSf.ZHAN Yan ZHAO GuoZe UNSWORTH Martyn WANG LiFeng CHEN XiaoBin LI Tao XIAO QiBin WANG JiJun TANG Ji CAI JunTao WANG YanZhao 2013Chinese Science Bulletin2013,58,28:39

10A Positioning System based on Communication Satellites and the Chinese Area Positioning System(CAPS)显示文摘The Chinese Area Positioning System(CAPS) is a positioning system based on satellite communication that is fundamentally different from the 3'G'(GPS,GLONASS and GALILEO) systems.The latter use special-purpose navigation satellites to broadcast navi-gation information generated on-board to users,while the CAPS transfers ground-generated navigation information to users via the communication satellite.In order to achieve accurate Positioning,Velocity and Time(PVT),the CAPS employs the following strategies to over-come the three main obstacles caused by using the communication satellite:(a) by real-time following-up frequency stabilization to achieve stable frequency;(b) by using a single carrier in the transponder with 36 MHz band-width to gain sufficient power;(c) by incorporating Decommissioned Geostationary Orbit communication satellite(DGEO),barometric pressure and Inclined Geostationary Orbit communication satellite(IGSO) to achieve the 3-D posi-tioning.Furthermore,the abundant transponders available on DGEO can be used to realize the large capacity of communication as well as the integrated navigation and communication.With the communication functions incorporated,five new functions appear in the CAPS:(1) combination of navigation and communication;(2) combination of navigation and high accu-racy orbit measurement;(3) combination of navigation message and wide/local area differen-tial processing;(4) combination of the switching of satellites,frequencies and codes;and(5) combination of the navigation message and the barometric altimetry.The CAPS is thereby labelled a PVT5C system of high accuracy.In order to validate the working principle and the performance of the CAPS,a trial system was established in the course of two years at a cost of about 20 million dollars.The trial constellation consists of two GEO satellites located at E87.5° and E110.5°,two DGEOs located at E130° and E142°,as well as barometric altimetry as a virtual satellite.Static and dynamic performance tests were completed for the Eastern,the Western,the Northern,the Southern and the Middle regions of China.The evaluation results are as follows:(1) land static test,plane accuracy range:C/A code,15~25m;P code,5~10 meters;altitude accuracy range,1~3 m;(2) land dynamic test,plane accuracy range,C/A code,15~25m;P code,8~10m;(3) velocity accuracy,C/A code,0.13~0.3ms-1,P code,0.15~0.17ms-1;(4) timing accuracy,C/A code,160ns,P code,13 ns;(5) timing compared accuracy of Two Way Satellite Time and Frequency Transfer(TWSTFT),average accuracy,0.068ns;(6) random error of the satellite ranging,10.7 mm;(7) orbit determination accuracy,better than 2 m.The above stated random error is 1σ error.At present,this system is used as a preliminary operational system and a complete system with 3 GEO,3 DGEO and 3 IGSO is being established.Guo-Xiang Ai Hu-Li Shi Hai-Tao Wu Yi-Hua Yan Yu-Jing Bian Yong-Hui Hu Zhi-Gang Li Ji Guo Xian-De Cai 2008Chinese Journal of Astronomy and Astrophysics2008,8,6:33
11Holocene vegetational and climatic variation in westerly-dominated areas of Central Asia inferred from the Sayram Lake in northern Xinjiang,China显示文摘Changes in the vegetation and climate of the westerly-dominated areas in Central Asia during the Holocene were interpreted using pollen-assemblages and charcoal data from a 300-cm-long sediment core of the Sayram Lake,northern Xinjiang.Accele-rator Mass Spectrometry(AMS) radiocarbon dating methods were applied to bulk organic matter of the samples.Artemisia spp./Chenopodiaceae ratios and results from principal component analysis were used to infer that the lake basin was dominated by desert vegetation before ca.9.6 cal.ka BP,which suggests a warm and dry climate in the early Holocene.Desert steppe/steppe expanded during 9.6-5.5 cal.ka BP,indicating a remarkable increase both in the precipitation and temperature during the mid-Holocene.Desert vegetation dominated between 6.5 and 5.5 cal.ka BP,marking an extreme warmer and drier interval.The steppe/meadow steppe recovered,and temperatures decreased from 5.5 cal.ka BP in the late Holocene,as indicated by the increased abundance of Artemisia and the development of meadows.Holocene temperatures and moisture variations in the Sayram Lake areas were similar to those of adjacent areas.This consistency implies that solar radiation was the main driving factor for regional temperature changes,and that the effect of temperature variations was significant on regional changes in humidity.The evolution of climate and environment in the Sayram Lake areas,which were characterized as dry in the early Holocene and relatively humid in the middle-late Holocene,are clearly different from those in monsoonal areas.Dry conditions in the early Holocene in the Sayram Lake areas were closely related to decreased water vapor advection.These conditions were a result of reduced westerly wind speeds and less evaporation upstream,which in turn were caused by seasonal changes in solar radiation superimposed by strong evaporation following warming and drying local climate.JIANG QingFeng JI JunFeng SHEN Ji Ryo MATSUMOTO TONG GuoBang QIAN Peng REN XueMei YAN DeZhi 2013Science China Earth Sciences2013,56,3:32

13Role and limitation of FMPSPGR dynamic contrast scanning in the follow-up of patients with hepatocellular carcinoma treated by TACE显示文摘AIM:To evaluate the role and limitation of fast multiplanarspoiled gradient-recalled (FMPSPGR) MR dynamiccontrast scanning in the follow-up of patients with HCCtreated by transarterial chemoembolization (TACE).METHODS:Twenty-two patients with 24 HCC lesionsconfirmed by biopsy or surgical resection underwentMR imaging in 4-9wks after TACE with a superconducting1.5 T MR scanner, including SE T1WI, T2WI and FMPSPGRdynamic contrast scanning. The signal intensities of alllesions on SE T1WI, T2WI and the enhancement patternson FMPSPGR dynamic contrast scanning were observed,and the comparison was made between MRI findingsand pathological results in ail the cases.RESULTS:Of the 24 lesions, the signal intensities werevarious on SE T1WI and T2WI. On T1WI, 13 lesionsappeared as hyperintense, 4 lesions were isointenseand the other 7 lesions were hypointensese.Histologically, hyperintense lesions showed on T1WIwere viable tumor or hemorrhage; isointensities werecoagulative necrosis or inflammatory infiltration;hypointensities were tumor, liquified necrosis,coagulative necrosis or inflammatory infiltration. OnT2WI, 15 lesions appeared as hyperintense, 3 lesionswere isointense and the other 6 lesions werehypointensese. Hyperintense lesions showed on T2WIwere residuals of viable tumor, hemorrhage, liquefiednecrosis or inflammatory infiltration; isointense lesionswere residuals of viable tumor or inflammatoryinfiltration; hypointense lesions were coagulativenecrosis. On FMPSPGR dynamic contrast scanning, 18of the 24 lesions enhanced on early-phase dynamicscanning conesponding to residuals of viable tumor andthe other 6 lesions had no enhancement at this phasebecause complete necrosis were seen in the histologicexamination. On delayed-phase dynamic scanning, 6lesions had permanent enhancement appeared asinhomogeneous hyperintensity and both residuals ofviable tumor and inflammatory infiltration were foundby histologic examination. 18 lesions were hypointenseat this phase and 8 of them coexisted with peripheralring-like enhancement of the lesions resulting fromviable tumors or inflammatory infiltration.CONCLUSION: FMPSPGR MR dynamic contrast scanningcan reflect the pathologic changes of HCC treated byTACE. Especially, early-phase dynamic scanning canevaluate accurately residuals of viable tumor andnecrosis in HCC lesions. FMPSPGR dynamic contrastscanning is useful in the follow-up of patients with HCCtreated by TACE combined with SE T1WI and T2WI, butit is difficult to differentiate peripheral viable tumorsfrom inflammatory infiltration.Fu-Hua Yan Kang-Rong Zhou Jie-Min Cheng Jian-Hua Wang Zhi-Ping Yan Reng-Rong Da Department of Radiology,Zhongshan Hospital,Fudan University,Shanghai 200032,China Jia Fan Department of Hepatobiliary-surgery,Zhongshan Hospital,Fudan University,Shanghai 200032,China Yuan Ji Department of Pathology,Zhongshan Hospital,Fudan University,Shanghai 200032,China 2002World Journal of Gastroenterology2002,8,4:32
14Current cancer burden in China: epidemiology, etiology, and prevention显示文摘Cancer has become the most common cause of death in China.Owing to rapid economic development,improved livelihood,and shifts in risk factors,cancer epidemiology has experienced substantial changes during the past several decades.In this review,we aim to describe the current cancer epidemiology of the main types of cancer in China,report major risk factors associated with cancer development,and summarize the contributions of the Chinese government to controlling the cancer burden.A total of 4,064,000 new cases were diagnosed in China in 2016.The most frequent types are lung cancer(828,100;20.4%),colorectal cancer(408,000;10.0%),and gastric cancer(396,500;9.8%).Lung(657,000;27.2%),liver(336,400,13.9%),and stomach(288,500;12.0%)cancers are the 3 most deadly cancers in the general population.The 5-year survival rate for cancer has dramatically increased in recent decades.However,liver and particularly pancreatic cancers still have the poorest prognosis.The main modifiable risk factors associated with cancer development include infectious agents,smoking,alcohol consumption,obesity,unhealthful dietary habits,and inadequate physical activity.The Chinese government has made unremitting efforts to decrease the cancer burden,including cancer education and investment in cancer screening programs.Maomao Cao He Li Dianqin Sun Siyi He Xinxin Yan Fan Yang Shaoli Zhang Changfa Xia Lin Lei Ji Peng Wanqing Chen 2022Cancer Biology & Medicine2022,19,8:33
15An Investigation of Oxidative DNA Damage in Pharmacy Technicians Exposed to Antineoplastic Drugs in Two Chinese Hospitals Using The Urinary 8-OHdG Assay显示文摘Objective To investigate oxidative DNA damage in pharmacy technicians preparing antineoplastic drugs at the PIVAS (Pharmacy Intravenous Admixture Service) in two Chinese hospitals.Methods Urinary 8-OHdG served as a biomarker.5-Fluorouracil (5-FU) concentrations in air,masks and gloves were determined.The spill exposure of each PIVAS technician to antineoplastic drugs was investigated.Eighty subjects were divided into exposed group I,II,and control group I,II.Results 5-FU concentration ratios for gloves and masks in exposed group I were significantly higher than those in exposed group II (P<0.05 or P<0.01).The average urinary 8-OHdG concentrations in exposed group I,control group I,exposed group II,and control group II were 14.69±0.93,10.68±1.07,10.57±0.55,and 11.96±0.73 ng/mg Cr,respectively.Urinary 8-OHdG concentration in exposed group I was significantly higher than that in control group I or that in exposed group II (P<0.01).There was a significant correlation between urinary 8-OHdG concentrations and spill frequencies per technician (P<0.01).Conclusion There was detectable oxidative DNA damage in PIVAS technicians exposed to antineoplastic drugs.This oxidative DNA damage may be associated with their spill exposure experience and contamination of their personal protective equipment.HUANG Yu Wen JIAN Le ZHANG Mei Bian ZHOU Quan YAN Xiao Feng HUA Xu Dong ZHOU Ying HE Ji Liang 2012Biomedical and Environmental Sciences2012,25,1:30
16Waist Circumference Reference Values for Screening Cardiovascular Risk Factors in Chinese Children and Adolescents显示文摘Objectives To explore the optimal threshold values of waist circumference(WC)for detecting cardiovascular(CV)risk factors among Chinese children and adolescents.Methods Association of WC with CV risk factors was studied among 65 898 children aged 7-18 years whose data were pooled from nine previous studies in China.CV risk factors in this study included hypertension(blood pressure above 95 percentile levels),dyslipidemia(with one or more of the following three indexes:TG≥1.7 mmol/L,TC≥5.18 mmol/L,and HDL-C≤1.04 mmol/L)and elevated glucose level(fasting plasma glucose ≥5.6 mmol/L).Receive-operating characteristic analysis(ROC)and logistic regression were employed to derive optimal age-and sex-specific waist circumference references for predicting CV risk factors.Results A slight increasing trend of CV risk factors was observed starting from the 75th percentile of waist circumference in the study population,while a remarkable increasing trend occurred from the 90th percentile.The optimal waist circumference thresholds for predicting high blood pressures were at the 75th percentile for both boys and girls,which was at the 90th percentiles for detecting at least two of the above three CV risk factors.In comparison with children with waist circumference below the 75th percentile,the odds ratio of two CV risk factors doubled among children with waist circumference between the 75th and the 90th percentile,and increased by 6 times among children with waist circumference above the 90th percentile.The trend of high blood pressure increasing with waist circumference remained significant after having been stratified by BMI category.Conclusion The 75th and the 90th percentiles of WC are the optimal cut-off points for predicting an increased and a substantially increased risk of CV factors in Chinese children and adolescents,respectively.GUAN-SHENG MA CHENG-YE JI JUN MA JIE MI R1TA YT SLING FENG XIONG WEI-LI YAN XIAO-QI HU YAN-PING LI SONG-M1NG DU HONG-YUN FANG AND J1NG-XIONG JIANG 2010Biomedical and Environmental Sciences2010,23,1:25

18Antidepressant-like effect of essential oil of Perilla frutescens in a chronic, unpredictable, mild stress-induced depression model mice显示文摘Perilla frutescens(Perilla leaf), a garnishing vegetable in East Asian countries, as well as a plant-based medicine, has been used for centuries to treat various conditions, including depression. Several studies have demonstrated that the essential oil of P. frutescens(EOPF) attenuated the depressive-like behavior in mice. The present study was designed to test the anti-depressant effects of EOPF and the possible mechanisms in an chronic, unpredictable, mild stress(CUMS)-induced mouse model. With the exposure to stressor once daily for five consecutive weeks, EOPF(3, 6, and 9 mg·kg-1) and a positive control drug fluoxetine(20 mg·kg-1) were administered through gastric intubation to mice once daily for three consecutive weeks from the 3rd week. Open-field test, sucrose consumption test, tail suspension test(TST), and forced swimming test(FST) were used to evaluate the behavioral activity. The contents of 5-hydroxytryptamine(5-HT) and its metabolite, 5-hydroxyindoleacetic acid(5-HIAA), in mouse hippocampus were determined by HPLC–ECD. Serum interleukin(IL)-1, IL-6, and tumor necrosis factor(TNF)-α levels were evaluated by enzyme-linked immunosorbent assay(ELISA). The results showed that CUMS significantly decreased the levels of 5-HT and 5-HIAA in the hippocampus, with an increase in plasma IL-6, IL-1β, and TNF-α levels. CUMS also reduced open-field activity, sucrose consumption, as well as increased immobility duration in FST and TST. EOPF administration could effectively reverse the alterations in the concentrations of 5-HT and 5-HIAA; reduce the IL-6, IL-1β, and TNF-α levels. Moreover, EOPF could effectively reverse alterations in immobility duration, sucrose consumption, and open-field activity. However, the effect was not dose-dependent. In conclusion, EOPF administration exhibited significant antidepressant-like effects in mice with CUMS-induced depression. The antidepressant activity of EOPF might be related to the relation between alteration of serotonergic responses and anti-inflammatory effects.JI Wei-Wei LI Rui-Peng LI Meng WANG Shu-Yuan ZHANG Xian NIU Xing-Xing LI Wei YAN Lu WANG Yang FU Qiang MA Shi-Ping 2014Chinese Journal of Natural Medicines2014,12,10:26
19Surveillance, epidemiology, and pathogen spectrum of hand, foot, and mouth disease in mainland of China from 2008 to 2017显示文摘Hand,foot and mouth disease(HFMD)was reported in May 2,2008 to be the 38th legally notifiable disease in China's National Notifiable Disease Reporting and Surveillance System.In order to solve the infection,an extensive three-level HFMD surveillance laboratory network was established.In this study,the framework of that network is assessed and the incidence of HFMD in China from 2008 to 2017 is reported using a descriptive epidemiologic method.During these 10 years,a series of techniques have been widely applied in all the network laboratories.Using information and material obtained from the network,a virus bank and database containing 18,238 viruses were established.Nationally,18,184,834 HFMD cases,including 152,436 severe cases and 3633 fatal cases,were reported in mainland of China.The average annual incidence in the population was 133.99/100,000 people,with a maximum incidence of 205.06/100,000 people in 2014.The incidence and mortality rates of HFMD were the highest in children aged 1–2 years.The numbers of reported cases fluctuated,with a high incidence observed every 2 years.An overall increase in the number of reported cases was also observed throughout the study period.Despite this,the incidence of severe cases and the mortality rate have been decreasing.High-risk regions are located in southern,eastern,and central China.Two peaks of HFMD infection cases were observed annually except for Northeast China.Different proportions of enterovirus serotypes were observed during the studied years.The predominant enterovirus varies from year to year,but the disease severity is always closely related to the specific serotype.EV-A71 is the dominant serotype associated with severe and fatal cases,with constituent ratios of 70.03%and 92.23%,respectively.The studied highly sensitive and efficient surveillance network provides information that is critical for prevention and control of the disease.It is extremely necessary and important to continuously conduct extensive virological surveillance for HFMD.Tianjiao Ji Taoli Han Xiaojuan Tan Shuangli Zhu Dongmei Yan Qian Yang Yang Song Aili Cui Yan Zhang Naiying Mao Songtao Xu Zhen Zhu Dandan Niu Yong Zhang Wenbo Xu 2019Biosafety and Health2019,1,1:26
20Epithelioid angiomyolipoma of the liver:Cross-sectional imaging findings of 10 immunohistochemically-verified cases显示文摘AIM:To retrospectively evaluate the computed tomography(CT)/magnetic resonance imaging(MRI) imaging features of epithelioid angiomyolipoma of the liver(Epi-HAML),with pathology as a reference. METHODS:The CT/MRI findings(number,diameter, lobar location,and appearance of lesions)in a series of 10 patients with 12 pathologically proven epithelioid angiomyolipomas of the liver were retrospectively analyzed.The imaging features,including attenuation/ signal intensity characteristics,presence of fat, hypervascular,outer rim,and vessels within lesion, were evaluated and compared with that of non-Epi-HAML in 11 patients(13 lesions).The Fisher exact test was used to compare difference in probability of imaging features between the two types. RESULTS:For 21 patients,CT images of 15 patients and MR images of six patients were available.No patient underwent two examinations.For the 15 patients with a CT scan,all HAML lesions in the two groups(10 Epi-HAML and seven non-Epi-HAML) manifested as hypoattenuation.For the six patients with MRI,all lesions(two Epi-HAML and six non-Epi- HAML)were hypointense on T1WI(fat suppression)and hyperintense on T2WI.There were 10 non-Epi-HAML, but only two Epi-HAML lesions showed the presence offat,which significantly different between the two types (P=0.005).On the dynamic contrast enhancement (DCE)imaging,eight Epi-HAML,and 13 non-Epi lesions manifested as hypervascular.Punctate or curved vessels were displayed in 10 Epi-HAML as well as in nine non-Epi lesions and outer rim enhancement could be found with eight Epi-HAML as well as six non-Epi lesions. CONCLUSION:Little or no presence of adipose tissue was found to be an imaging feature of Epi-HAML,compared with the non-Epi type.In addition, hypervascularity with opacification of central punctiform or filiform vessels on DCE would be a characteristic enhancement pattern for Epi-HAML.Peng-Ju Xu Yan Shan Fu-Hua Yan Yuan Ji Ying Ding Mei-Lin Zhou 2009World Journal of Gastroenterology2009,15,36:24
