雌性大鼠、小鼠生殖系统与人子宫内膜甾体激素分泌细胞的研究

对雌性大鼠、小鼠的生殖系统,人的子宫内膜与蜕膜进行了3-β-羟基甾体脱氢酶(3-β-HSDH)和脂类的组织化学研究。结果表明:在大鼠和小鼠的卵巢内,颗粒黄体细胞和膜黄体细胞3-β-HSDH呈强阳性反应,卵泡膜内层细胞与间质细胞呈中等程度阳性反应;大鼠与小鼠子宫内膜的表面上皮与腺上皮呈阳性反应;人早孕期蜕膜中的子宫腺上皮细胞与大蜕膜细胞呈阳性反应:在大鼠与小鼠的输卵中偶尔见到阳性反应物质;在人的子宫内膜中,没有见到阳性反应。本研究证明,雌性大鼠和小鼠除卵巢有分泌甾体素的功能外,子宫也有分泌甾体激素的功能。人早孕期蜕膜组织中的子宫腺与大蜕膜细胞都能分泌甾体激素。     

竹荪深层发酵菌丝体对小鼠免疫功能的影响及其抗肿瘤作用

过对食药用真菌──竹荪深层发酵菌丝体提取液对小鼠免疫功能及S－180肿瘤细胞的作用观察，表明其发酵菌丝体可明显提高小鼠腹腔巨噬细胞的吞噬功能（P＜0．01），并显著增加免疫器官的重量（P＜0．05）；对小鼠S－180肿瘤的抑瘤率为40．63％。     

肺癌脑转移83例临床分析

我所内科１９８８￣１９９３年收治肺癌患者１００６例，脑转移８３例，占８．２５％，由于治疗方法不同，其预后极其不同。手术切除加放疗化疗与单纯放疗化疗的生存率有显著性差异（Ｐ〈０．０５），放疗化疗综合组疗效预后好于单一治疗组（Ｐ〈０．０５）。因此在肺癌确诊后应常规作脑影像学检查，可早期诊断，这是提高疗效和生存捏的重要因素。     

女孩雌激素受体基因6号内含子区域两个新SNPs位点报道

目的：在女性性早熟患儿中检测雌激素受体基因6号外显子及内含子基因序列可能存在的突变。方法：PCR扩增雌激素受体基因6号外显子及内含子，对扩增产物进行DNA序列分析。结果：在6号内含子一侧，发现两个100％连锁的单核苷酸多态性(SNPs)，分别为．53G—67A和53T—67G。结论：这一对单核苷酸多态性并不引起氨基酸的替代，与女孩性早熟的发生也无关，但是否和其他疾病有连锁关系尚待进一步探讨。     

AⅡ受体拮抗剂ACEI对慢性肾衰患者血浆ANF及RAS的影响

目的了解血管紧张素Ⅱ受体拮抗剂(ATRA)和转换酶抑制剂(ACEI)对慢性肾衰(CRF)高血压患者血浆心钠素(ANF)和肾素*.血管紧张素系统(RAS)的影响。方法受试者口服氯沙坦(Los组)或福辛普利(Fos组)连续12周，于治疗前和治疗后第4、8及12周测定坐位舒张压(SiDBP)、血清尿素氮(BUN)、血清肌酐(SCr)、ANF、血管紧张素Ⅰ(AⅠ)和血管紧张素Ⅱ(AⅡ)。用SPSS7.0软件作统计分析。结果经12周治疗，两组患者SiDBP均降至目标值。Fos组与治疗前比较，AⅡ下降，ANF和Scr升高(P<0.01)。Los组AⅡ明显升高(P<0.01)，ANF在短暂升高后降至治疗前水平，Scr无变化。结论ACEI可能对CRF高血压患者肾内灌注压有影响，ANF动态改变可作为肾内灌注压变化的指标之一。ATRA对肾内灌注压影响小于ACEI。     

Management und Kontrolle einer Influenzapandemie Konzeptionelle Überlegungen für einen deutschen Influenzapandemieplan

The World Health Organization (WHO) and the majority of the influenza experts assume that an influenza pandemic might reemerge again at any time. Therefore WHO has called upon all member states to set up a national pandemic preparedness plan. For Germany such a plan is long overdue. In order to gain as much time as possible early identification of the pandemic virus is of highest priority. Furthermore progression of a pandemic is influenced by the time needed to develop a subtype specific vaccine as well as by the vaccines availability. However, in case of a pandemic a shortage of vaccines and prophylactic pharmaceuticals cannot be avoided. Therefore, decisions have to be made in order to establish priorities concerning the vaccination and the prophylactic and/or therapeutic antimicrobial treatment of selected sub-populations. There is also a need to lay down measures ensuring the distribution of vaccines and antiviral drugs, adequate health care and ambulance service, and the organization of dignified funerals of the deceased. It is also necessary to enter into an early agreement with vaccine manufacturers on a guaranteed supply of respective batches of vaccine doses. In addition procedures should be established to allow an increase in vaccine production in case of a pandemic. There is also a need for early agreements with the manufacturers of antiviral agents and for a decision concerning the establishment of a national stockpile to guarantee an adequate supply. Some measures must already be taken in the inter-pandemic period. Those are: enhancement of surveillance and research, development of new vaccines and new methods of vaccine production, licensing of new vaccines in case of a pandemic and establishment of a national influenza committee. Problems like the effectiveness of antiepidemic measures, such as immigration control and the closing of schools, must be solved in advance of a pandemic.     

高频超声检测颈动脉内膜-中层厚度及外周血管内皮功能评价动脉粥样硬化

目的 探讨高频超声检测颈动脉内膜-中层厚度与肱动脉内皮依赖性舒张功能在动脉粥样硬化中的诊断价值.方法 冠状动脉造影的老年患者69例及青年志愿者20例,分别行颈动脉超声检查,同时采用充气加压法测定肱动脉血流介导的内径扩张值,超声测值与冠脉造影结果对照分析.结果 ①颈动脉内膜-中层厚度值随粥样硬化斑块的增多、冠脉狭窄程度的加重而增高;②动脉粥样硬化患者在内膜-中层厚度值增高之前即可出现内皮功能损伤,肱动脉内径扩张值降低早于内膜-中层厚度值增高之前出现,内径扩张值随冠脉狭窄程度加重而下降.结论 高频超声检测颈动脉内膜-中层厚度、内径扩张值诊断早期动脉粥样硬化敏感性高,并且有助于对冠脉狭窄程度作出判断.

Objective:To explore the effect of thrombolysis with anticoagulation treatment forearly stage of deep vein thrombosis of lower extremity.Methods:The clinical data of 10 patients at the early stage of deep vein thrombosis(DVT)in the lower extremuites treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively.Results:The thrombolytic effect was significant.After treatment,the deep veins were recanalized without regurgitation in 75.3% of the patients.The total effective rate was 100%.Only three patients had hemorrhagic complication,but none of the patients died.Conclusion:Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.
