2Status monitoring and health assessment of Luhuitou fringing reef of Sanya, Hainan, China显示文摘The monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. The mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem.ZHANG Qiaomin SHI Qi CHEN Gang FONG T C W WONG D C C HUANG Hui WANG Hankui ZHAO Meixia 2006Chinese Science Bulletin2006,51,B12:15

9中国社区卫生服务该怎样满足患者需求:一项全国性的代表性调查显示文摘目的中国自2009年起开展社区卫生服务,截至2014年已建成社区卫生服务中心8 669家,拥有社区卫生服务工作者30万人。然而,至社区卫生服务中心就诊的患者数并不多,因为人们对全科医生缺乏信任,但对专科医生过度依赖。方法于2015年9—12月,采用分层随机抽样法,按社区卫生服务中心在城市和郊区的分布比例(2∶1)在中国东、中、西部地区抽取样本社区卫生服务中心,并采用不同问卷对在其工作的资深临床医生和全科医生进行调查。两套问卷内容均涉及所在社区卫生服务中心的服务人口特征、开办的临床和健康教育活动情况。158例资深临床医生和3 580例全科医生对调查进行了有效应答,问卷有效应答率分别为84%和86%。结果社区卫生服务中心的中位医生数为8例、中位护士数为13例,但仅半数医生注册为全科医生,极少数护士接受过专业的全科培训。98%的社区卫生服务中心配有听诊器,97%配有血压计,但仅43%配有检眼镜,64%配有妇科检查仪器。社区卫生服务中心倾向于有选择地向部分慢性病患者提供医疗服务。全科医生每天接诊的中位患者数为12.5例。多因素分析结果显示,在举办主体为私立医院的社区卫生服务中心、配有药剂师和护士的社区卫生服务中心,全科医生的每日接诊患者数较多。结论中国拥有规模较大的、以年轻人为主的全科医疗服务团队,并配有持续性专业培训;社区卫生服务中心配有基础医疗设备,但仅少数可为患者提供多种常见病的综合性医疗服务;社区卫生服务中心就诊患者数仍较少。WONG W C W JIANG S ONG J J 本刊编辑部 2017中国全科医学2017,20,19:6
10Fatty liver in hepatitis C patients post-sustained virological response with direct-acting antivirals显示文摘AIM To determine steatosis and fibrosis prevalence in hepatitis C patients after a sustained virological response achieved with direct-acting antivirals.METHODS Transient elastography with controlled attenuation parameter(CAP) was used to assess hepatic steatosis post-sustained virological response(SVR);the CAP technology was not available in the United States at study initiation.Liver stiffness/fibrosis was measured before and 47 wk after treatment completion.Patients with genotype 3 and patients with cirrhosis were excluded.RESULTS One hundred and one patients were included in the study.Post-SVR there were decreases from baseline in alanine aminotransferase(ALT)(63.1 to 17.8 U/L),aspartate aminotransferase(51.8 to 21.5 U/L) and fibrosis score(7.4 to 6.1 k Pa)(P < 0.05).Post-SVR,48 patients(47.5%) had steatosis on CAP;of these,6.25% had advanced fibrosis.Patients with steatosis had higher body mass index(29.0 vs 26.1 kg/m2),glucose(107.8 vs 96.6 mg/d L),ALT(20.4 vs 15.3 mg/d L),CAP score(296.3 vs 212.4 d B/m) and fibrosis score(7.0 vs 5.3 k Pa);P < 0.05.Interestingly,compared to baseline,both patients with and without steatosis had change in fibrosis score post-SVR(7.7 k Pa vs 7.0 k Pa and 7.0 k Pa vs 5.3 k Pa);alternatively,(P < 0.05) and therefore patients with steatosis continued to have clinically significant stiffness(≥ 7 k Pa).CONCLUSION Fatty liver is very common in hepatitis C virus(HCV) patients post-SVR.These patients continue to have elevated mean fibrosis score(≥ 7 k Pa) compared to those without fatty liver;some have advanced fibrosis.Long term follow up is needed to assess steatosis and fibrosis in HCV patients post-SVR.Mazen Noureddin Micaela M Wong Tsuyoshi Todo Shelly C Lu Arun J Sanyal Edward A Mena 2018World Journal of Gastroenterology2018,24,11:6
11基于安全可靠性的多类用户交通分配模型显示文摘为探究出行安全对用户出行选择行为的影响,提出了考虑事故风险成本和旅行时间的多类用户交通分配模型。针对事故发生的随机性特征,定义了路径出行安全可靠性概念,并以此计算用户的事故风险成本预算,体现出行者的安全偏好。基于考虑事故机会和事故风险的基础事故预测模型,针对路段和交叉口的不同特征,分别定义了路段和交叉口的事故风险成本分布。构建的交叉口事故风险成本模型,体现了交叉口不同转向的事故风险成本的差异性。为了求解基于安全可靠性的多类用户交通分配模型,采用路径配流法和相继平均法设计了相应的求解算法,并通过算例分析了模型和算法的有效性。研究结果表明:安全可靠性在用户出行选择中具有重要影响。当在广义出行费用中考虑事故风险成本时,出行者会更多地选择事故风险成本较小的路径;不同风险倾向的用户会有不同的选择特征,保守型出行者倾向于选择路径事故风险成本标准差相对较小的路径,即事故风险成本波动小的路径,而中立型出行者倾向于选择事故风险成本均值相对较低的路径;考虑交叉口的事故风险成本与否会直接影响流量分配结果,即路径交叉口数量和转向的差异性同样会影响出行者的选择。所提出的模型对于客流预测和网络安全评价与管理具有潜在的应用价值。黄合来 蒋梦曦 韩春阳 徐光明 WONG S C ABDEL-ATY M 2018中国公路学报2018,31,4:5

16Recurrent ectopic pancreatitis of the jejunum and mesentery over a 30-year period显示文摘BACKGROUND:Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position,with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography(CT)and magnetic resonance cholangiopancreatography(MRCP),and confirmed on histological review of the resection. METHODS:A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis.She had similar episodes over the past 30 years with unrevealing investigations,and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP,with findings suggestive of ectopic pancreas,a diagnosis confirmed on histology of the resection. RESULTS:MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas,with a small duct draining into a proximal jejunal loop.The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans,an occasional ductular structure,and admixed areas of adipose tissue.The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION:In an individual with abdominal pain,elevated serum amylase/lipase,but imaging findings of a normal native pancreas,ectopic pancreatitis should be considered,and can be evaluated by CT and MRCP.John CT Wong Charlotte Robinson Edward C Jones Alison Harris Charles Zwirewich Robert Wakefield Richard K Simons Eric M Yoshida 2011Hepatobiliary & Pancreatic Diseases International2011,10,2:4
