目的 观察肝康胶囊对慢性乙型肝炎的疗效。方法 36例慢性中度肝炎随机分为二组,治疗组给予肝康胶囊口服,每日3次,每次6～8粒,连服1个月为一疗程,根据病情可连服2～3个疗程;对照组给服大黄蛰虫丸,疗程同前。在服药期间定期查肝功能、γ球蛋白、血清透明质酸(HA)、Ⅲ型前胶原(PCⅢ)、Ⅳ型胶原(C-Ⅳ)和层粘蛋白(LN)。结果 治疗组丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)和总胆红素(TB)下降速度明显快于对照组;自觉症状的改善情况也好于对照组;3个疗程后治疗组各项肝纤维化指标以及γ球蛋白均较治疗前显著下降(P<0.01),而对照组变化不甚明显。结论 肝康胶囊对慢性肝炎有良好的抗纤维化和改善肝功能作用。     

乳舒胶囊镇痛、抗炎作用研究

目的：研究乳舒胶囊(RS)的镇痛、抗炎药效。方法：采用RS灌胃给药后，分别用甩尾法、热板法、扭体法研究RS对乳腺增生模型大鼠及小鼠的镇痛作用，分别用二甲苯法、琼脂法研究RS抑制小鼠耳廓炎症及大鼠慢性炎症性肉芽肿的作用。结果：乳舒胶囊能提高乳腺增生模型大鼠和小鼠的痛阈值、能减少醋酸致扭体疼痛小鼠的扭体次数、延长其发生扭体的潜伏期，有明显的镇痛作用；还可以抑制琼脂所致的大鼠肉芽肿和二甲苯致小鼠耳肿胀，有明显的抗炎作用。结论：乳舒胶囊镇痛、抗炎作用明显、疗效确切。     

Detection of abnormal lesions recorded by capsule endoscopy: A prospective study comparing endoscopist''s and nurse''s accuracy

BACKGROUND AND STUDY AIM: Capsule endoscopy is a non-invasive technique for small bowel examination but its evaluation is time consuming. The aim of this study was to assess whether, following adequate training, an endoscopy nurse is capable of picking up all significant images without reducing the diagnostic accuracy of the procedure. PATIENTS AND METHODS: Between April 2003 and December 2004, a total of 41 consecutive capsule endoscopy studies were blindly reviewed by both an endoscopy nurse and an endoscopist. The two operators had to select all significant images independently and to complete a structured questionnaire. Thirty-nine capsule endoscopy examinations (two studies discharged for premature battery failure) were evaluated. The agreement between the two operators was calculated by kappa statistics (coefficient of agreement). RESULTS: Agreement was excellent for all kind of selected lesions (mean kappa>0.85); the agreement was complete (kappa=1) for site identification, active bleeding, stenosis and negative studies. The greater disagreement (kappa=0.77) was found in cases of subtle mucosal abnormalities (i.e. reduction of villi), which were over-estimated by the nurse. CONCLUSIONS: The preview recordings made by the nurse may increase the cost/effectiveness of the study, by considerably reducing the time needed for the endoscopist to make the final report (about 5-10 min), without compromising final diagnosis.     

仙灵骨葆胶囊改善精液质量的临床研究

目的:观察仙灵骨葆胶囊改善男性不育患者精液质量的情况。方法:女方生育功能正常的男性不育患者66例,口服仙灵骨葆胶囊2~4个月,观察治疗前后精液质量并进行精子形态学分析。结果:治疗2个月后,精子密度有所提高,但无统计学差异(P>0.05);精子存活率和活动率也无明显变化(P>0.05);治疗后正常形态精子百分率明显升高,其中正常形态精子百分率≥15%者,由治疗前的25.8%(17/66)增加为57.6%(38/66)(P<0.05),而正常形态精子百分率<9%者,由治疗前的53.0%(35/66)下降为25.8%(17/66);7例少精子症者用药前精子正常形态百分率平均为5.8%,服药4个月后平均为10.9%,与服药前有明显差异(P<0.05)。治疗期间有5例患者配偶怀孕。结论:仙灵骨葆胶囊对男性精液质量有改善作用,能明显提高正常形态精子百分率,少精子症者更明显。

我国人体首次发现圆圃棘口吸虫病例及虫体形态观察

1988年7月6日,我们在一患者便内发现似姜片虫卵的大型虫卵。临床表现为头昏无力、食欲不振,上腹痛和贫血。因病人20天前有吞食活泥鳅史,故疑其为棘口吸虫病。服药后获虫体70条,经形态学研究,鉴定为圆圃棘口吸虫(Echinostoma hortense Asada,1926)。     

Site-specific homologous recombination mutagenesis in group B streptococci

We describe the use of suicide vectors to generate site-specific mutations in group B streptococcus. This is accomplished by cloning gene-specific sequences into a temperature sensitive plasmid and selecting for clones which have undergone homologous recombination. The recombinan clones can be easily isolated by selecting for clones which have retained the antibiotic resistance markers that are present on the vector or cloned into the gene-specific sequences. To confirm the fidelity of the recombination events, PCR analysis is performed on chromosomal DNA isolated from the recombinant clones. Using this strategy, we have generated site- specific insertions in several capsule genes and have found that these insertions occurred as expected and that the mutations result in loss of capsule expression. In this report, we specifically detail the construction of cpsB mutants by single and double cross-over recombination and demonstrate that the resulting strains are acapsular.
