紫癜1号中药熏洗治疗小儿过敏性紫癜临床观察

目的观察紫癜1号中药熏洗治疗小儿过敏性紫癜的临床效果。方法选取收治的过敏性紫癜患者80例,按照研究方法的不同分为观察组和对照组,对照组患者40例,给予喜炎平注射液、维生素C注射液、葡萄糖酸钙注射液等进行治疗;观察组患者在对照组基础上采用紫癜1号中药熏洗进行治疗,比较2组患者的临床治疗效果、皮肤紫癜消退时间及关节肿痛缓解状况等相关指标。结果对照组患者的治疗有效率为75.0%,观察组患者的治疗有效率为97.5%,观察组治疗有效率显著高于对照组;观察组患儿皮肤紫癜消退时间为(4.10±1.02)d,少于对照组(7.69±1.79)d;观察组患者经治疗后关节肿痛情况完全缓解达到50.0%,缓解达到35.0%,明显优于对照组。结论紫癜1号中药熏洗治疗小儿过敏性紫癜,治疗效果明显,有效缩短患者紫癜消退时间及缓解关节痛的程度。     

中药熏洗治疗膝关节骨性关节炎的Meta分析

为运用循证医学方法对中药熏洗治疗膝骨性关节炎（OA）的临床疗效及安全性进行系统评价和Meta分析。全面收集了中药熏洗治疗OA的文献资料。在严格质量评价基础上，对研究结果进行定性分析。合并各篇优、良为阳性结果，中、差为阴性结果。利用RevMan4．1软件对多个研究结果的总体疗效进行固定效应模型的Meta分析，并进行敏感性分析。用漏斗图表示发表性偏倚。结果显示，中药熏洗治疗OA的效应值OR=2．68.95％可信区间为[1．82，3．95]；敏感性分析显示效应值稳定；漏斗图图形不对称；无中药熏洗不良反应的报道。表明中药熏洗治疗OA有一定的疗效，由于漏斗图提示存在发表性偏倚，加上现有临床研究存在的方法学问题，现在的研究结论有一定的局限性，欲得出公认的结论，尚有待进行设计严谨的多中心、随机对照试验。     

Plasma Separator for Encapsulating Fluorescent Probe in Erythrocytes

Using a plasma separator, it is possible to wash large volumes of whole blood free of plasma proteins in short periods. The novelty, however, is that the same apparatus can be used to reversibly hemolyze and reseal the red blood cells (RBCs) using hypotonic and hypertonic dialysates, respectively. This technique was assessed using the fluorescent exogenous agent uranin (fluorescein sodium). Results indicate that the encapsulation of the RBCs can be completed in under 2 h. The encapsulation efficiency of the RBCs was approximately 80% with a RBC recovery rate of 75%.

中药泡洗治疗糖尿病足90例疗效分析

目的为了观察中药泡洗对糖尿病足的疗效。方法对90例糖尿病足患者用中药（方剂组成：桃仁、红花、桂枝、没药、乳香、花椒、川芎等各10g）水煎制后分为2袋各300ml配合足浴仪泡洗，2次，d，30min／次，10d为1疗程。结果全组90例患者显效66例，有效24例，总有效率100％。结论中药泡洗治疗糖尿病足疗效确切。     

精子洗涤对精液中HBV DNA含量的影响

目的：检查HBV感染者精液是否存在乙型肝炎病毒（HBV），探讨精子洗涤是否能去除其中的HBV DNA。方法：用实时荧光定量PCR（FQ-PCR）法检测57名血清HBsAg阳性患者精液中HBV DNA，采用Percoll非连续梯度离心及上游法分离其中21份精液，并对洗涤后标本进行HBV DNA检测。结果：62份精液标本中有15份HBV DNA阳性，阳性率为24.19%;21份用于洗涤的精液标本中有，有7份HBV DNA阳性，洗涤后仍有6份标本阳性。结论：部分HBV感染者精液具有传染性，精子洗涤不能完全去除精液中的乙肝病毒。将HBV感染者的精液用于人工授精或体外受精应慎重。     

Investigation of, the cause of low sperm motility in asthenozoospermic patients by multiple quantitative tests

Multiple tests were done on the ejaculates of 10 asthenozoospermic patients and nine healthy normozoospermic volunteers in an attempt to identify individually the cause of low sperm motility in these patients. Possible defects in the sperm plasma membrane and the motility apparatus of sperm, and in epididymal function affecting the development of motility, were investigated. The presence of seminal sperm antibodies or any motility-inhibiting factors in the seminal plasma that could be removed by washing were also tested. Each test was positive in only one or two patients but axonemal dysfunction was identified in nine patients. Removal of seminal plasma from asthenozoospermic samples did not improve sperm motility to any greater extent than with donor ejaculates, and the motile sperm of these patients exhibited characteristics mostly similar to those of donors under various incubation conditions. Selection procedures are, therefore, required to obtain samples of good quality sperm from such asthenozoospermic ejaculates.     

An Evaluation of the Residual Activity of Antiseptic Handrub Lotions: An ‘In Use’ Setting Study

An evaluation of the residual activity of quick-drying agents (alcoholic solutions) used for hygienic hand disinfection is described. We looked for residual efficacy following hand disinfection with soap and water alone or followed by one of two alcoholic handrub lotions supplied from an automatic hand washing machine. The bacterial counts on the hands obtained before and within 2 successive hours after disinfection showed that alcoholic chlorhexidine was the most effective for 10 minutes after contamination of the hands. WELPAS® (alcoholic chlorbenzarconium) followed this in its immediate effect and was better than soap and water alone. There were no significant differences after 30‘ or 120‘ between the three disinfecting methods.

Phosphate poisoning by ingestion of clothes washing liquid and fabric conditioner

A case of deliberate ingestion of clothes washing liquid and fabric conditioner is described. Tracheal intubation and controlled ventilation became necessary because of respiratory muscle dysfunction associated with hypocalcaemia. We suggest that the phosphate component of the clothes washing liquid was responsible for the dramatic metabolic upset and subsequent need for admission to the Intensive Care Unit.
