小儿急性中毒77例临床分析及预防

本文对近 10年收治 77例急性中毒的患儿进行了回顾性分析。观察到 :年幼小儿、农村小儿发病率较高 ,因误服药物、鼠药的食物致急性中毒的患儿较多 ,死亡病例均因就诊太晚。提示 :对急性中毒必须早诊断、早治疗。并提出减少小儿意外中毒的关键应从预防着手     

Potential preventive strategies and therapies in urinary tract infection

There are perhaps five strategies either presently advocated or under investigation for prevention of recurrent urinary tract infection (UTI): antibiotics, including natural peptides; functional foods; vaccines; probiotics; and miscellaneous, including avoidance of spermicides and maintenance of good hygiene. It is not possible to state the proportion of patients using antibiotics versus foods such as cranberry or using alternative approaches such as avoidance of spermicides. The majority of women who are referred to specialists will be prescribed long-term, low-dose antibiotics. However, given the magnitude of the problem, it is safe to state that large numbers of women are at least experimenting with alternative remedies such as drinking of cranberry juice or ingestion of herbal remedies with a view to enhancing their immune response. Vaccine development remains a long way from human use and has yet to be developed for organisms other than Escherichia coli. The use of probiotics to restore the normal vaginal flora and provide a competitive bacterial barrier to pathogens is close to becoming available as an alternative preventive approach. The next decade should see the introduction of new methods for reduction of the high incidence of UTI and better management of recurring urogenital infections.     

妊娠晚期人类小DNA病毒B19感染情况,母婴传播及与早产或小于胎龄儿关系的研究

为了解妊娠晚期人类小ＤＮＡ病毒Ｂ１９（ＨＰＶＢ１９）感染情况、母婴传播及与早产或小于胎龄儿的关系，将１０４例母亲及其新生儿分成两组，试验组包括１９例早产儿、３２例小于胎龄儿及其母亲；对照组包括５３例正常新生儿及其母亲。采用聚合酶链反应技术（ＰＣＲ）检测母血、脐血和胎盘组织ＨＰＶＢ１９ＤＮＡ；用鼠抗Ｂ１９单克隆抗体和Ｂ１９联合抗原（ＶＰ１＋ＶＰ２）建立了捕获式ＥＬＩＳＡ法检测母血和脐血ＨＰＶＢ１９特异性ＩｇＭ抗体。结果：１０４例母血中，ＨＰＶＢ１９ＩｇＭ阳性２例（１．９％），１０４例脐血中阳性３例（２．９％）。在母血、脐血及胎盘组织各１０４例中检出ＨＰＶＢ１９ＤＮＡ阳性分别为６例、４例、６例。因此试验组５１对母婴共１０２例中６例有ＨＰＶＢ１９感染（５．９％）；对照组５３对母婴共１０６例中２例有ＨＰＶＢ１９感染（１．９％）。两组Ｂ１９感染率差异无显著意义。提示：在北京地区，妊娠晚期存在Ｂ１９急性感染，应引起重视；Ｂ１９感染与早产或小于胎龄儿的发生可能不相关；新生儿Ｂ１９感染是通过胎盘传播的。对有Ｂ１９感染证据的新生儿进行随访及研究如何阻止胎盘传播很重要。     

乳腺癌根治术后皮瓣坏死的综合防治策略

皮瓣坏死为乳腺癌术后常见并发症之一，国内外文献报道其发生率均较高。我们根据自己的临床体会、结合文献资料认为导致皮瓣坏死的主要原因为皮瓣组织细胞损伤、皮瓣张力过大、皮下积液及感染、真皮及真皮下血液循环障碍，并针对以上原因采取一系列相应措施，取得了较好疗效，同时对已发生坏死皮瓣的处理进行了简要论述。     

Large Scale Manufacturing of B43(Anti-CD19)-Genistein for Clinical Trials in Leukemia and Lymphoma

We have conjugated the murine monoclonal anti-CD 19 antibody B43 to the tyrosine kinase inhibitor genistein to construct an effective immunoconjugate against CD 19 antigen positive hematologic malignancies. The scaled-up production and purification of B43 antibody, genistein, and B43-Genistein immunoconjugate permitted the manufacturing of a highly purified clinical-grade B43-Genistein preparation. In clonogenic assays, B43-Genistein elicited selective and potent cytotoxicity against CD 19 antigen positive human leukemia cells. To our knowledge, this work represents the first effort of producing a clinical-grade genistein immunoconjugate for treatment of B-lineage leukemia and lymphoma.     

乙状结肠造口术并发症73例分析

（目的）探讨乙状结肠造口术并发症的防治。（方法）1985年至1995年间进行了202例乙状结肠造口术。（结果）与造口有关的并发症73例，包括造口周围炎35例、造口狭窄21例、造口结肠旁疝6例、造口出血4例、造口肠管回缩3例、造口肠管脱垂2例、造口肠管坏死2例。73例并发症病人经治疗均痊愈出院。（结论）重视手术操作能降低并发症的发生率，术后加强观察和护理，早期发现和处理是提高治疗成功率的关键。     

川山橙化学成分的研究

从川山橙Melodinushemsleyanus中分得10个化合物，用光谱方法和化学反应鉴定了它们的结构，分别为：11-hydroxytabersonine（Ⅰ），scandine（Ⅱ），10-hydroxyscandine（Ⅲ），tubotaiwine（Ⅳ），tubotaiwineN－oxide（Ⅴ），15α－hydroxykopsinine（Ⅵ），vincoline（Ⅶ），19R－vindolinineN－oxide（Ⅷ），16β-hyaroxy－19R－vindolinine（Ⅸ）和16β-hydroxy－19S－vindolinineN－oxide（Ⅹ），其中Ⅹ为新化合物，药理筛选表明化合物Ⅰ有一定的抗肿瘤活性。
