Analysis of Risk and Burden of Dysentery Associated with Floods from 2004 to 2010 in Nanning,China

This study aimed to examine the association between floods and the morbidity of dysentery and to quantify the burden of dysentery due to floods in Nanning, China. A generalized additive mixed model was conducted to assess the relationship between monthly morbidity of dysentery and floods from 2004 to 2010. The years lived with disability (YLDs) of dysentery attributable to floods were then estimated based on the WHO framework of the burden of disease study for calculating the potential impact fraction. The relative risk (RR) of floods on the morbidity of dysentery was 1.44 (95% confidence interval [CI] = 1.18–1.75). The models suggest that a potential 1-day rise in flood duration may lead to 8% (RR = 1.08, 95% CI = 1.04–1.12) increase in the morbidity of dysentery. The average attributable YLD per 1,000 of dysentery caused by floods were 0.013 in males, 0.005 in females, and 0.009 in persons. Our study confirms that floods have significantly increased the risk and the burden of dysentery in the study area. Public health action should be taken to prevent and control the potential risk of dysentery after floods. Vulnerable groups such as males and children should be paid more attention.

羽毛球运动中发生手腕和肩袖损伤的相关因素调查

目的：通过对羽毛球爱好者的问卷调查，结合羽毛球项目的运动特点，分析常见的运动损伤部位及其发病原因、处理方法以及预防措施. 方法：调查于2005—03／11在成都医学院体育教研室羽毛球俱乐部完成，对156名羽毛球爱好者进行运动损伤情况凋查，均自愿参加调查。采用问卷调查和专家访谈相结合的方法，主要结合羽毛球项目的运动特点，调查运动损伤的患病率、损伤类型及其受伤原因，分析其常用的处理方法及预防措施。 结果：共发放问卷156份，收回内容详实问卷156份。（1）损伤患病率：运动损伤患病率为78，84％。（2）损伤类型：156名羽毛球爱好者中急性损伤占52、56％，慢性损伤占26，28％。最容易受伤的手腕处受伤患病率为37．39％，其次是肩袖受伤患病率为30．89％。（3）受伤原因：技术动作不规范是运动损伤最主要的原因，占72，35％，而准备活动不充分和身体疲劳分别占63、41％和22．76％. 结论：为有效预防手腕和肩袖损伤，应加强局部肌肉力量训练等防治措施；注意学习和掌握正确的动作技术要领，做好充分的准备活动是十分必要的.     

Soluble triggering receptor expressed on myeloid cells-1 in acute respiratory infections.

Levels of the soluble form of the triggering receptor expressed on myeloid cells (sTREM)-1 are elevated in severe sepsis. However, it is not known whether sTREM-1 measurements can distinguish milder bacterial infections from noninfectious inflammation. The present authors studied whether serum sTREM-1 levels differ in community-acquired pneumonia, exacerbations of chronic obstructive pulmonary disease (COPD), asthma and controls, and whether sTREM-1 may be used as a surrogate marker for the need for antibiotics. Serum sTREM-1 levels in 150 patients with pneumonia, COPD and asthma exacerbations and 62 healthy controls were measured. Serum sTREM-1 levels were significantly elevated in pneumonia (median 295.2 ng x mL(-1)), COPD (280.3 ng x mL(-1)) and asthma exacerbations (184.0 ng x mL(-1)) compared with controls (83.1 ng x mL(-1)). Levels were higher in pneumonia and Anthonisen type 1 COPD exacerbations than in type 2 and 3 COPD and asthma exacerbations. The area under the receiver operating characteristics curve for sTREM-1 as a surrogate marker for the need for antibiotics was 0.77. Serum levels of the soluble form of the triggering receptor expressed on myeloid cells-1 were elevated predominantly in pneumonia and Anthonisen type 1 COPD exacerbations versus type 2 and 3 chronic obstructive pulmonary disease exacerbations, asthma and controls. Serum levels of the soluble form of the triggering receptor expressed on myeloid cells-1 has moderate but insufficient accuracy as a surrogate marker for the need for antibiotics in lower respiratory tract infections.     

山药粗多糖的提取工艺

对鲜山药中水溶性粗多糖的提取工艺进行了研究,通过单因素试验和L9（34）正交试验,研究了料液比、提取温度、时间和乙醇体积分数对粗多糖得率的影响,极差分析及方差分析结果表明提取温度和料液比是影响山药粗多糖提取的主要因素,较优的工艺为料液比1 g：9 mL,温度50 ℃,时间2.5 h,乙醇体积分数75%,在此工艺条件下,鲜山药粗多糖得率为0.2449%（以鲜山药质量计）.     

益气补血活血法治疗阳痿病57例临床观察

目的:观察中医益气补血活血法治疗阳痿病的临床疗效。方法:将符合诊断的114例阳痿病患者随机分为治疗组和对照组各57例,患者入院后分别进行阴茎硬度测试和FSH(促滤泡激素)、HCG(人绒毛膜促性腺激素)、PRL(泌乳素)测定。对照组予温肾壮阳中药加常规西药治疗;治疗组予自拟益气补血活血法方药加减治疗,并辅以精神疏导。对两组病例的疗效进行总结和随访。结果:114例病例全部得到随访,治疗组治愈率63.12%,总有效率91.23%;对照组分别为50.87%;68.41%。两组比较,治疗组优于对照组(P<0.05)。结论:采用中医益气补血活血法治疗阳痿病疗效显著,尤对血管性阳痿病显效。
