外伤性股动脉栓塞继发肾功能衰竭32例的综合治疗

目的 探讨外伤性股动脉栓塞后继发急性肾功能衰竭的临床综合治疗。方法 对32例外伤性股动脉栓塞术后继发急性肾功能衰竭病例均进行急诊手术切开取栓、血管吻合术，术后均予以综合治疗。结果住院时间7天-3个月，平均41d。最终截肢6例，死亡2例，24例修复成功。结论 术前准确判断预后，正确选择手术方式、术中筋膜减张性切开、术后及时清除坏死组织、术后利尿合剂应用和及时必要的血透是影响外伤性股动脉栓塞保肢术后急性肾功能衰竭预后的重要因素。     

神经导航下经岩骨幕上下联合入路中面神经管的解剖研究

OBJECTIVE: To study the value of neuronavigation in the transpetroal approach, and to provide anatomic data for the protection of the nerves in the facial nerve canal (FNC) during surgeries. METHODS: Simulated surgery through the transpetroal approach was performed on 16 sides of 8 adult cadaver heads with the assistance by neuronavigation. The anatomy of the facial nerve and the relationship of related structures were observed and the distances from the utmost external edge of the mastoid to different segments of the FNC were measured. RESULTS: Neuronavigation was successful with all the FNC, with the mean error of less than 0.9 mm. The FNC could be divided into 3 segments, the labyrinthine, the tympanic and the mastoid segments, stretching 3.6+/-1.2 mm, 11.2+/-2.5 mm and 16.1+/-3.6 mm respectively and with diameters of 1.2+/-0.3 mm, 1.4+/-0.1 mm and 1.7+/-0.2 mm, respectively. CONCLUSION: Neuronavigation may help protect the FNC during surgical procedures, and a thorough knowledge of the anatomic features of the FNC can be significant for preservation of the facial nerves.     

北京农村居民健康状况及卫生服务需求调查

目的了解北京农村居民健康状况及卫生服务需求特点。方法从昌平区、顺义区、大兴区、房山区随机抽取25～64岁农民1605人进行统一问卷调查。结果农民高血压自报患病率为22．4％，超重和肥胖率为56．1％；现在吸烟率为34．4％，缺乏运动率为41．6％；家庭主要经济支出为学生上学(35．3％)，建房(25．4％)和疾病(21．2％)；54．9％家庭医疗费用支出占总收入的10％以上；最关心的健康问题主要是慢性疾病防治(70．2％)；最希望获得的健康知识是慢性病预防知识(72％)；希望获得健康知识的途径是广播和电视(81％)；家庭最希望获得的医疗保健服务是方便看病和获得药物(73．8％)。结论慢性病给农民带来沉重负担，并成为农民关心的主要健康问题。     

Association of the expressions of platelet-derived growth factor receptor and c-Fos with the biological characteristics of bladder cancer.

OBJECTIVE: To elucidate the relation of platelet-derived growth factor receptor (PDGFR) and c-Fos protein expressions with human bladder transitional epithelial cell carcinoma (BTCC). METHODS: The expressions of PDGFR and c-Fos were investigated in 11 normal bladder tissue samples, 14 adjacent non-carcinoma tissues and 43 BTCC tissues by means of SP immunohistochemical technique. RESULTS: The c-Fos expression was found in the cell nuclei and cytoplasm, and PDGFR in the nuclear membrane, cytoplasm, and cellular membrane. PDGFR and c-Fos were detected in 81.40% and 48.83% of the BTCC tissues respectively, at the rates both significantly higher than those in normal and adjacent non-carcinoma tissues (P<0.05). Correlation between the expression of c-Fos and the tumor grading was noted (P<0.05). The expressions of PDGFR and c-Fos in tumor blood vessels were significantly higher than those in normal vessels. CONCLUSIONS: The expressions of PDGFR and c-Fos might be involved in the development of BTCC, possibly related to the angiogenesis of the tumors. c-Fos expression can indicated the cell proliferative status of the BTCC.     

维拉帕米灌注治疗前列腺术后膀胱痉挛性疼痛的临床疗效观察

为探讨前列腺术后膀胱痉挛性疼痛的药物治疗效果，将２６例前列腺增生行耻骨上经膀胱前列腺摘除术后频繁发作膀胱逼尿肌无抑制性收缩导致膀胱痉挛性疼痛者，按随机抽样法分为两组，第１组１５例接受维拉帕米膀胱灌注治疗，第２组１１例作为对照，不用任何可能影响下尿中功能的药物。     

羊水细胞培养宫内诊断的应用(附120例分析)

报告120例羊膜腔穿刺羊水细胞培养结果:在成功的99例中,发现二例染色体异常,核型为47,xy,+18和46,xx/47,xx,+F,在21例失败中出现一例眼球畸形。培养成功率为82.5%;染色体异常检出率为2.02%。无一例因羊膜腔穿刺而导致流产,但出现一例轻度羊水栓塞合并症。并对羊水细胞培养在产前宫内诊断中应用价值及术后并发症进行了讨论。     

加压滑动鹅头钉治疗股骨转子间骨折的临床与实验研究

探讨加压滑动鹅头钉在治疗股骨转子间骨折中的作用。临床应用４５例。男３４例，女１１例。平均年龄６１岁。稳定型１３例，不稳定型３２例。经临床应用和生物力学实验测定，结果表明：（１）对不稳定型转子间骨折，恢复小转子区内后侧皮质骨的连续性在骨折的稳定中具有重要作用。（２）内后侧骨折块解剖复位，加压螺丝钉固定或大转子骨折端加压螺丝钉固定能显著增强加压滑动鹅头钉的固定作用，明显提高不稳定型转子间骨折的术后稳定性。（３）该装置设计合理，性能坚固，对转子间骨折具有很强的固定作用，能有效地达到早期下床和避免长期卧床的目的，是目前临床最理想的内固定装置。
