32018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
4Relationship Between Grain Yield and Yield Components in Super Hybrid Rice显示文摘Chinese super hybrid rice breeding project has developed many new varieties with great yield potential. It is controversial which yield component should be emphasized in super hybrid rice production. The present study was conducted to compare super hybrid rice with common hybrid and super inbred rice and analyze contributions of yield components to grain yield of super hybrid rice under experimental conditions, and evaluate relationships between grain yield and yield components of super hybrid rice in farmer’s paddy fields. Field experiments were done in Changsha, Guidong, and Nanxian, Hunan Province, China, from 2007 to 2009. Eight super hybrid varieties, one common hybrid variety, and one super inbred variety were grown in each location and year. Rice production investigation was undertaken in high-yielding (Guidong), moderate-yielding (Nanxian), and low-yielding (Ningxiang) regions of Hunan Province, China, in 2009. Grain yield and yield components were measured in both the field experiments and rice production investigation. Super hybrid rice varieties outyielded common hybrid and super inbred varieties across three locations and years. Yield potential has been increased by 11.4% in super hybrid rice varieties compared with common and super inbred varieties. The higher yield of super hybrid varieties was attributed to improvement in panicle size. Panicles per m2 had the highest positive contribution to grain yield with the exception under yield level of 10.0 to 12.0 t ha-1, and was positively related to grain yield in farmer’s field at all of the high-, moderate-, and low-yielding regions. Our study suggests that panicle per m2 ought to be emphasized in super hybrid rice production.HUANG Min ZOU Ying-bin JIANG Peng XIA Bing Md Ibrahim AO He-jun 2011Agricultural Sciences in China2011,10,10:41
5Clinical efficacy of tolvaptan for treatment of refractory ascites in liver cirrhosis patients显示文摘AIM: To evaluate the efficacy and safety of tolvaptan to treat refractory ascites in decompensated liver cirrhosis patients with or without further complications, such as hepatorenal syndrome and/or hepatocellular carcinoma.METHODS: Thirty-nine patients(mean age 55 years, males: 32) with decompensated liver cirrhosis and refractory ascites were enrolled. All patients received a combination of tolvaptan(15 mg/d for 5-14 d) and diuretics(40-80 mg/d of furosemide and 80-160 mg/d of spironolactone). The etiology of cirrhosis included hepatitis B(69.2%), hepatitis C(7.7%) and alcohol-in-duced(23.1%). Changes in the urine excretion volume, abdominal circumference and edema were assessed. The serum sodium levels were also measured, and adverse events were recorded. A follow-up assessment was conducted 1 mo after treatment with tolvaptan.RESULTS: Tolvaptan increased the mean urine excretion volume(1969.2 ± 355.55 mL vs 3410.3 ± 974.1 mL, P < 0.001), and 89.7% of patients showed improvements in their ascites, 46.2% of whom showed significant improvements. The overall efficacy of tolvaptan in all patients was 89.7%; the efficacies in patients with hepatocellular carcinoma and hepatorenal syndrome were 84.2% and 77.8%, respectively. The incidence of hyponatremia was 53.8%. In patients with hyponatremia, the serum sodium levels increased after tolvaptan treatment(from 128.1 ± 4.22 mEq/L vs 133.1 ± 3.8 mEq/L, P < 0.001). Only mild drug-related adverse events, including thirst and dry mouth, were observed. CONCLUSION: Tolvaptan is a promising aquaretic for the treatment of refractory ascites in patients with decompensated liver cirrhosis.Xin Zhang Shu-Zhen Wang Jun-Fu Zheng Wen-Min Zhao Peng Li Chun-Lei Fan Bing Li Pei-Ling Dong Lei Li Hui-Guo Ding 2014World Journal of Gastroenterology2014,20,32:36
6Outbreak of Dengue Fever in Central China,2013显示文摘In 2013,the first dengue fever(DF) outbreak in central China was reported in the central of Henan province,northern temperate regions,although they have been sequentially recorded in Southern China.106 suspected DF cases were reported and 73 patients were confirmed dengue virus type 3(DEN-3) infections.62/392(15.8%) local health persons showed DEN antibodies positive.To this day Henan is the northernmost province in China which has been reported about outbreak of DF and what is important is that it warns us the endemic range of DF has been expanded geographically in China.HUANG Xue Yong MA Hong Xia WANG Hai Feng DU Yan Hua SU Jia LI Xing Le TANG Xiao Yan MA Hong Peng ZU Bing Can ZHANG Qiao Hong CHEN Hao Min XU Bian Li 2014Biomedical and Environmental Sciences2014,27,11:30
7Relationship between Cognition Function and Hippocampus Structure after Long-term Microwave Exposure显示文摘Objective To analyze the effects of long-term microwave exposure on hippocampal structure and function in the rat.Methods Experiments were performed on 184 male Wistar rats(three exposure groups and a sham group).Microwaves were applied daily for 6 min over 1 month at average power densities of 2.5,5,and 10 mW/cm2.Learning and memory abilities were assessed by Morris water maze.High performance liquid chromatography was used to detect neurotransmitter concentrations in the hippocampus.Hippocampal structures were observed by histopathological analysis.Results Following long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d,14 d,and 1 m in all three microwave exposure groups.Neurotransmitter concentrations of four amino acids(glutamate,aspartic acid,glycine,and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group.There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups.Further,mitochondria became swollen and cristae were disordered.The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.Conclusion These data suggest that the hippocampus can be injured by long-term microwave exposure,which might result in impairment of cognitive function due to neurotransmitter disruption.ZHAO Li PENG Rui Yun WANG Shui Ming WANG Li Feng GAO Ya Bing DONG Ji LI Xiang SU Zhen Tao 2012Biomedical and Environmental Sciences2012,25,2:27

13Outcome and costs of laparoscopic pancreaticoduodenectomy during the initial learning curve vs laparotomy显示文摘AIM:To compare laparoscopic pancreaticoduodenectomy(TLPD) during the initial learning curve with open pancreaticoduodenectomy in terms of outcome and costs.METHODS:This is a retrospective review of the consecutive patients who underwent TLPD between December 2009 and April 2014 at our institution.The experiences of the initial 15 consecutive TLPD cases,considered as the initial learning curve of each surgeon,were compared with the same number of consecutive laparotomy cases with the same spectrum of diseases in terms of outcome and costs.Laparoscopic patients with conversion to open surgery were excluded.Preoperative demographic and comorbidity data were obtained.Postoperative data on intestinal movement,pain score,mortality,complications,and costs were obtained for analysis.Complications related to surgery included pneumonia, intra-abdominal abscess,postpancreatectomy hemorrhage,biliary leak,pancreatic fistula,delayed gastric emptying,and multiple organ dysfunction syndrome.The total costs consisted of cost of surgery,anesthesia,and admission examination.RESULTS:A total of 60 patients,including 30 consecutive laparoscopic cases and 30 consecutive open cases,were enrolled for review.Demographic and comorbidity characteristics of the two groups were similar.TLPD required a significantly longer operative time(513.17 ± 56.13 min vs 371.67 ± 85.53 min,P < 0.001).The TLPD group had significantly fewer mean numbers of days until bowel sounds returned(2.03 ± 0.55 d vs 3.83 ± 0.59 d,P < 0.001) and exhaustion(4.17 ± 0.75 d vs 5.37 ± 0.81 d,P < 0.001).The mean visual analogue score on postoperative day 4 was less in the TLPD group(3.5 ± 9.7 vs 4.47 ± 1.11,P < 0.05).No differences in surgery-related morbidities and mortality were observed between the two groups.Patients in the TLPD group recovered more quickly and required a shorter hospital stay after surgery(9.97 ± 3.74 d vs 11.87 ± 4.72 d,P < 0.05).A significant difference in the total cost was found between the two groups(TLPD 81317.43 ± 2027.60 RMB vs laparotomy 78433.23 ± 5788.12 RMB,P < 0.05).TLPD had a statistically higher cost for both surgery(24732.13 ± 929.28 RMB vs 19317.53 ± 795.94 RMB,P < 0.001)and anesthesia(6192.37 ± 272.77 RMB vs 5184.10 ± 146.93 RMB,P < 0.001),but a reduced cost for admission examination(50392.93 ± 1761.22 RMB vs 53931.60 ± 5556.94 RMB,P < 0.05).CONCLUSION:TLPD is safe when performed by experienced pancreatobiliary surgeons during the initial learning curve,but has a higher cost than open pancreaticoduodenectomy.Chun-Lu Tan Hao Zhang Bing Peng Ke-Zhou Li 2015World Journal of Gastroenterology2015,21,17:19
14Is total laparoscopic pancreaticoduodenectomy superior to open procedure? A meta-analysis显示文摘BACKGROUND Laparoscopy has been widely used in general surgical procedures,but total laparoscopic pancreaticoduodenectomy(TLPD)is still a complex and challenging surgery that is only performed in a small number of patients at a few large academic medical centers.Although the safety and feasibility of TLPD have been established,few studies have compared it with open pancreaticoduodenectomy(OPD)with regard to perioperative and oncological outcomes.Therefore,we carried out a meta-analysis to evaluate whether TLPD is superior to OPD.AIM To compare the treatment outcomes of TLPD and OPD in order to assess the safety and feasibility of TLPD.METHODS We conducted a systematic search of studies comparing TLPD with OPD that were published in the PubMed,EMBASE,and Cochrane Library databases through December 31,2018.The studies comparing TLPD and OPD with at least one of the outcomes we were interested in and with more than 10 cases in each group were included in this analysis.The Newcastle-Ottawa scale was used to assess the quality of the nonrandomized controlled trials and the Jadad scale was used to assess the randomized controlled trials.Intraoperative data,postoperative complications,and oncologic outcomes were evaluated.The metaanalysis was performed using Review Manager Software version 5.3.Random or fixed-effects meta-analyses were undertaken to measure the pooled estimates.RESULTS A total of 4790 articles were initially identified for our study.After screening,4762 articles were excluded and 28 studies representing 39771 patients(3543 undergoing TLPD and 36228 undergoing OPD)were eventually included.Patients who underwent TLPD had less intraoperative blood loss[weighted mean difference(WMD)=-260.08 mL,95%confidence interval(CI):(-336.02,-184.14)mL,P<0.00001],a lower blood transfusion rate[odds ratio(OR)=0.51,95%CI:0.36-0.72,P=0.0001],a lower perioperative overall morbidity(OR=0.82,95%CI:0.73-0.92,P=0.0008),a lower wound infection rate(OR=0.48,95%CI:0.34-0.67,P<0.0001),a lower pneumonia rate(OR=0.72,95%CI:0.60-0.85,P=0.0002),a shorter duration of intensive care unit(ICU)stay[WMD=-0.28 d,95%CI(-2.88,-1.29)d,P<0.00001]and a shorter length of hospital stay[WMD=-3.05 d,95%CI(-3.93,-2.17),P<0.00001],a lower rate of discharge to a new facility(OR=0.55,95%CI:0.39-0.78,P=0.0008),and a lower 30-d readmission rate(OR=0.81,95%CI:0.68-0.95,P=0.10)than those who underwent OPD.In addition,the TLPD group had a higher R0 rate(OR=1.28,95%CI:1.13-1.44,P=0.0001)and more lymph nodes harvested(WMD=1.32,95%CI:0.57-2.06,P=0.0005)than the OPD group.However,the patients who underwent TLPD experienced a significantly longer operative time(WMD=77.92 min,95%CI:40.89-114.95,P<0.0001)and had a smaller tumor size than those who underwent OPD[WMD=-0.32 cm,95%CI:(-0.58,-0.07)cm,P=0.01].There were no significant differences between the two groups in the major morbidity,postoperative pancreatic fistula,delayed gastric emptying,postpancreatectomy hemorrhage,bile leak,gastroenteric anastomosis fistula,intra-abdominal abscess,bowel obstruction,fluid collection,reoperation,ICU admission,or 30-d and 90-d mortality rates.For malignant tumors,the 1-,2-,3-,4-and 5-year overall survival rates were not significantly different between the two groups.CONCLUSION This meta-analysis indicates that TLPD is safe and feasible,and may be a desirable alternative to OPD,although a longer operative time is needed and only smaller tumors can be treated.Hua Zhang Xiang Lan Bing Peng Bo Li 2019World Journal of Gastroenterology2019,25,37:19

17Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun 2015Biomedical and Environmental Sciences2015,28,1:16

19DNA barcoding of the fungal genus Neonectria and the discovery of two new species显示文摘To determine a suitable DNA barcode for the genus Neonectria,the internal transcribed spacer rDNA,β-tubulin,EF-1α,and RPB2 genes were selected as candidate markers.A total of 205 sequences from 19 species of the genus were analyzed.Intra-and inter-specific divergences and the ease of nucleotide sequence acquisition were treated as criteria to evaluate the feasibility of a DNA barcode.Our results indicated that any single gene among the candidate markers failed to serve as a successful barcode,while the combination of the partial EF-1α and RPB2 genes recognized all species tested.We tentatively propose the combined partial EF-1α and RPB2 genes as a DNA barcode for the genus.During this study,two cryptic species were discovered,based on the combined data of morphology and DNA barcode information.We described and named these two new species N.ditissimopsis and N.microconidia.ZHAO Peng LUO Jing ZHUANG WenYing LIU XingZhong WU Bing 2011Science China(Life Sciences)2011,54,7:15
20Societal response to challenges of global change and human sustainable development显示文摘It is now widely accepted that carbon emission from human activities is an important driving force in global warming, and global change has a deep impact on sustainable development of human society. To meet the challenges of global change, the international community has reached a consensus that developed countries take strict actions in emission reduction, whereas developing countries take spontaneous efforts in reducing emissions under the guiding principle of common but differentiated responsibilities, with an agreed goal to restrict global surface temperature increase due to human activities to within 2℃ of pre-industrial levels. However, there is no clear pathway to reach this goal. A number of related questions must be addressed on principles to be followed, research emphasis and policy measures. Here we argue that response policies to address global change issues must be based on balanced development at regional and international levels, and on advancements in science and technology. This requires consideration of harmony not only between humans and nature but also within human societies, to properly deal with the relationship between global change and sustainable development. We must make equal efforts toward carbon emission reduction and carbon sequestration, and toward mitigation and adaptation. There should be more research support to reduce uncertainties in our understanding of global change. Addressing the challenges of global change creates great opportunities for the development of human society. This will facilitate transformation of energy use structure, improve and restore ecological functioning of the earth environment, transform production modes and ways of living in human society, and promote harmonic and balanced development at regional and international levels.XU GuanHua GE QuanSheng GONG Peng FANG XiuQi CHENG BangBo HE Bin LUO Yong XU Bing 2013Chinese Science Bulletin2013,58,25:15
