全国细菌药敏试验的室间质量评价

目的：了解全国大中型医院细菌药敏试验（AST）状况，提高检测水平和质量。方法：定期向全国各参加评价实验室发放冻干标本，要求在规定时间内报告可疑感染的病原菌及其药敏结果，对回报结果给予数据统计、分析和评价。结果：2000年全国489个细菌室对常见耐药菌的检测正确率分别为：超广谱β－内酰胺酶63％（ESBLs)；苯唑西林敏感金黄色葡萄球菌（MSSA）74％；苯唑西林耐药凝固酶阴性葡萄球菌（MRSCoN)48％；对青霉素不敏感肺炎链球菌7％；氨基糖苷类高水平耐药肠球菌95％；产β－内酰胺酶流感嗜血杆菌正确率35％。结论：通过细菌药敏试验的室间质量评价反映出我国的细菌耐药性检测水平急待提高。

关节镜技术的历史与新进展

现代的关节镜从膀胱镜演变而来，创伤小，适用广泛。近年膝关节镜技术在半月板病变处理上有逆行全切法等新方法，交叉韧带重建、软骨移植成为研究热点；关节镜技术除应用于肩关节及其它小间隙关节，还开展治疗弹响髓等关节外应用；个性化康复锻炼提高了手术疗效。     

冠心病患者体外反搏后心功能改变

应用体外反搏治疗33例冠心病患者,治疗前后进行心功能检查比较,结果是肺水指数下降4.19％(P<0.05),心室射血时间增加7.74％(P<0.05),射血流速指数增加5.39％(P>0.05),系统血管阻抗降低16.97％(P<0.001),心排量增加10％(P<0.01),心搏量增加13.32％(P<0.01),心率减慢6.66％(P<0.05),心搏指数增加13.23％(P<0.05),心脏指数增加10.63％(P<0.01),说明心功能检查有较好改善。     

Termination Of Sustained Tachycardia By External Noninvasive Pacing

Invasive cardiac pacing has proved useful in the induction and termination of reentrant sustained tachycardias. In one of our two cases, programmed ventricular extra-stimulation was used to induce sustained ventricular tachycardia from the endocardial surface of the right ventricle. Induced ventricular tachycardia was terminated by burst ventricular pacing with an external cardiac pacemaker. In our second patient, external pacing was effective at inducing and terminating sustained supraventricular tachycardia. These patients illustrate that the principles of terminating sustained reentrant tachycardia with invasive pacing may also apply to noninvasive external pacing. The usefulness of this approach in treating reentrant tachycardias needs further evaluation.     

Study on Tongkuaixiao Babu plaster in treating cancer pain

Objective: To explore the efficacy of Tongkuaixiao Babu plaster (TKXBBP) in treating cancer pain.Methods: In the clinical observation, sixty-five patients with moderate or severe cancer pain were randomly divided into two groups: 32 in the treated group (TKXBBP group) and 33 in the control group (Bucinnazine group). The therapeutic effects in relieving pain, improving quality of life (QOL), and the rate of satisfaction the patients felt of the two groups were compared respectively. Results: TKXBBP was effective in treating cancer pain. There wasn’t any statistically significant difference in total effective rate (P>0.05), but the statistical difference was significant in obvious remission rate (P<0.05) between the treated and control group, and the effect on serious pain shown in the treated group was better than that of the control group (P<0. 05). The difference in the initiation time of relieving cancer pain was insignificant (P>0.05), while in the remission period, the treated group showed its treatment was obviously superior to that of the control group (P<0.05). TKXBBP showed better effect in the improvement of QOL (P<0.05) and satisfaction rate, with significant difference between the treated and the control groups (P<0.01).Conclusion: TKXBBPs effect in treating cancer pain was obvious, its application was safe and convenient. It was shown that the external treatment with this kind of Chinese medicine had great advantage in treating cancer pain.     

胫腓骨下段开放性粉碎骨折的治疗(附20例临床报告)

目的探讨胫腓骨下段开放性粉碎骨折的综合治疗。方法20例胫腓骨下段开放性粉碎骨折采用半环槽式外固定器固定、皮瓣转移、腓骨内移、骨折端加压并同期行上干骺端骨延长等综合治疗方法。结果伤口均一期愈合，所有皮瓣均成活，骨折临床愈合平均时间19周，7例因严重骨缺损经骨折端加压并同期行上干骺端骨延长后肢体均恢复正常长度。无1例针眼感染和血管、神经损伤。临床优良率为90％(18／20)。结论a)半环槽外固定器能克服胫腓骨下段开放性粉碎骨折的治疗困难，具有立体均衡固定。刚性可调，避免肢体受压。便于再次创面处理以及同期行骨折端加压和肢体延长等优点。b)半环槽式外固定器结合皮瓣转移、腓骨内移以及骨折端加压并同期行上干骺端骨延长等综合治疗方法是胫腓骨下段开放性粉碎骨折可选择的较好治疗措施之一。     

一次手术治愈外直肌全麻痹

过去，为了保证前段的血液供应，外直肌全麻痹的手术治疗要分２～３次完成，考虑到全麻痹的外直肌已无功能，我们提出在这种条件下可以不动含睫状前动脉的外直肌，只退后内直肌和将上，下直肌的外侧１／２移到外直肌的附着处，如此安排，可以一次手术完成治疗，这样可以缩短治疗时间，减少病人的痛苦和负担，我们治疗了７例８眼，结果比较满意。
