采用一式三份数码对号入座法管理病案号

采用"对号入座法"管理病案号,先把姓名索引卡、病案封面、病案号索引簿预先印上号码.待病人入院,取出相应一式三份号码,做好各种索引.结果,派出的病案号被取出,乘下空白的是未使用.如果旧病友再次入院;就要在病案的姓名索引中或电脑中查找旧号,这样有效地控制重号、漏号.     

隆突性皮纤维肉瘤23例临床分析

本文报告了我科1978～1990年间收治的降突性皮纤维肉瘤23例,均经组织学证实.治疗以手术切除为主,术后局部复发率为65.2%.无一例发生转移.切除不彻底是复发的主要原因.作者指出广泛切除是防止复发的主要措施,手术前后的放疗有可能减少复发.     

中国中原地区33555名妇女妇科疾病发生情况与五种因素关系的调查报告

自１９９２年３月至１９９４年５月，对中原地区４个省２０多个县（市）近２００个单位３３５５５名２０～７５岁的已婚妇女，进行妇科疾病发生情况与年龄、职业、文化、月经、孕产等五种因素关系的调查分析。在３３５５５名妇女中，患病者２２３７０人，总患病率为６６．６７％，查出妇科疾病４２种，计７６９７４例次。结果证明：以２５～３５岁年龄组发病率最高，其中以内生殖器炎症为主；职业以经商者发病率高，特别是性病患者高于其他职业者二倍以上；文化程度以小学、初中者发病率高，尤其宫颈炎更明显；月经情况：随着经前期紧张综合征的加重，更年期综合征发病率增高；孕产次数越多，患病率越高。本次调查未发现宫颈癌，进一步证明我国对妇女保健工作的关心和重视。     

微波对超低温细胞复温的可行性研究和若干问题的探讨

采用微波炉中的谐振场和外辐射天线的平面波对冻存在－１９６℃的活细胞进行复温试验。结果表明：谐振场加温迅速但极不均匀，造成细胞大量死亡。平面电磁波微波泄漏大，效率低，加温时间过长，不能应用。本文阐述了微波对超低温细胞复温的可能性和现有微波仪不宜进行细胞复温的原因，并提出改进设计的建议。     

Antithrombotic effect of beta,beta''-monochloromethylene diadenosine 5'',5"''-P1,P4-tetraphosphate.

The feasibility of using beta,beta'-monochloromethylene diadenosine 5',5"'-P1,P4-tetraphosphate (AppCHCl-ppA) as an antithrombotic agent was studied in a rabbit intracarotid cannula thrombosis model previously shown to be sensitive to antiplatelet agents. This analogue, having a P-C-P bridge in place of a P-O-P internucleoside linkage, has been found resistant to phosphodiesterase activity. Rabbits were infused with the dinucleotide at a dose of 50 mg per kg over a 2-hr period, at a controlled rate by pump. A 1-cm length of polyethylene cannula (1 mm i.d.) was tied into the carotid artery. Animals were stable under general anesthesia during the entire period of the experiment. In the control group, 16 of 20 animals formed clots, an incidence of 80%, whereas in the test animals, 6 of the 20 formed clots (30% incidence, P < 0.05). After preincubation of whole blood with 50 microM AppCHClppA at 37 degrees C for up to 3 hr, a consistent suppression of ADP-induced platelet aggregation was observed. The present study suggests that AppCHClppA may be useful as an antithrombotic agent in certain clinical situations, such as hemodialysis, arteriovenous shunts, and introduction of artificial heart valves. It may also possibly prevent extension of recent clots. The toxicity and metabolism of AppCHClppA have, however, yet to be explored.     

Possible contribution of follicular interleukin-1beta to nitric oxide generation in human pre-ovulatory follicles

The aim of this study was to investigate the relationships between follicular nitric oxide (NO) metabolite concentrations and several related variables, with special reference to follicular interleukin- 1beta (IL-1beta). The follicular fluid from the leading and secondary follicles was collected individually from 20 women undergoing in-vitro fertilization (IVF) treatment, and the concentrations of nitrite (NO2-) and nitrate (NO3-) were determined fluorometrically using 2,3- diaminonaphthalene. Both follicular nitrite (r = 0.42, P < 0.01) and nitrate (r = 0.49, P < 0.001) were found to be significantly correlated with follicular IL-1beta concentrations. There were also significant positive correlations between follicular nitrate and the number of oocytes retrieved (P < 0.01) and serum oestradiol concentration on the day of human chorionic gonadotrophin (HCG) administration (P < 0.05). When follicular cells were incubated in vitro with 10 ng/ml of IL-1beta for 24 h, nitrate generation was significantly (P < 0.01) elevated compared with the control. In conclusion, our study demonstrates that follicular IL-1beta and the number of developing follicles are significant variables that affect follicular NO concentrations, and points to the possible contribution of IL-1beta to NO generation in human preovulatory follicles.      

Transforming growth factor J3 type II receptor (TGFpRII) mutation in gastric lymphoma without mutator phenotype

A new mutation in the serine-threonine klnase domain of the transforming growth factor β type II receptor (TGFpRII) was found in a case of diffuse, B cell non-Hodgkin's lymphoma of the stomach. A mfssense mutation (ACA to GCA, Thr to Ala) was detected In exon 5, and a wild type allele was also present. This Is the first naturally occurring mutation in the klnase domain of this gene identified in human primary lymphoma. The replication error at three loci was negative, and the poly A tract of exon 3, which is frequently a target of mismatch repair genes, was intact. Malignant lymphoma of B cell origin in the stomach Is an addition to an expanding catalogue of tumors with TGFβRII alterations, and the biological sequelae of the change in the functional domain and the clinical characteristics of the patient in this study are intriguing.     

Lack of correlation between expression of Epstein-Barr virus (EBV) latent membrane protein and bcl-2 oncoprotein in vivo.

AIMS--To evaluate whether there is any correlation between the expression of Epstein-Barr virus (EBV) latent membrane protein (LMP) and oncoprotein bcl-2 in the lymph node biopsy specimens of a Chinese patient with EBV-related reactive lymphoproliferation who later developed T cell lymphoma after a short period of time. METHODS--Immunohistochemistry, with a standard alkaline phosphatase antialkaline phosphatase (APAAP) method and New Fuchsin as a chromogen, was used for single staining of bcl-2 or LMP. Double immunostaining combining APAAP and indirect immunofluorescence was performed for dual labelling of LMP and bcl-2. RESULTS--bcl-2 was expressed in 10-30% of cells in the first lymph node biopsy specimen (EBV-associated lymphoproliferative disorder) and 30-50% of cells in the second lymph node biopsy specimen (T cell lymphoma). LMP was expressed in the first biopsy specimen but not in the second. Double immunostaining results showed that around 78% of LMP positive cells were bcl-2 negative and 94% bcl-2 positive cells were LMP negative. Among the very small fraction of LMP and bcl-2 double positive cells, the intensity of bcl-2 staining was heterogeneous and was not always stronger than that observed in LMP negative bcl-2 positive cells. CONCLUSIONS--The expression of bcl-2 protein is independent of LMP protein status in vivo. Several mechanisms may be involved in EBV associated lymphomagenesis, and bcl-2 induction may occur independently of LMP expression.
