Clinical and experimental studies on acupuncture treatment of apoplexy at the convalescent stage by consciousness-restoring method.

The consciousness-restoring method and the conventional method of acupuncture were used for treatment of 92 cases of apoplexy at the convalescent stage. They were randomly divided into 2 groups: the consciousness-restoring group (50 cases), and the conventional group (42 cases). The therapeutic results show that the cure rates in the former and latter groups are 43% and 16.67% respectively. The markedly effective and effective rates in the former group are significantly higher than that in the latter group. The experimental results demonstrate that there is remarkable improvement in the majority of criteria of blood rheology, blood lipid, micro-circulation and thrombus formation in vitro, in the former group, and the degree and extent of improvement are markedly better than the latter group.     

扩大的椎板间开窗治疗腰椎间盘突出伴侧隐窝狭窄（附140例报告）

本组采用的扩大的椎板开窗术治疗腰椎间盘突出合并侧隐窝狭窄140例。结果全部优良，与适应症严格选择和手术损伤小有关。强调切除卡压神经根的侧隐窝后壁外侧，即上关节突的冠状面．不失其脊椎三柱系统的三角结构。俯卧位头低足高，可减少硬膜囊张力避免负损伤。切除棘突下椎板时，用神经拉勾代替神经剥离器易于分离黄韧带，用90度的椎板咬骨钳斜向棘突方向，可满意地切除该部份椎板黄韧带，并可刮切椎板内层。神经根周围滴入醋酸炎舒松A2-3ml，术后疼痛锐减。减压窗口置盖明胶海绵有其争议，作者实践体会放置害处不大，要求病人有“护腰”意识。     

剌玫果对烹饪油烟引起小鼠骨髓PCE微核率增高的影响

本文研究了剌玫果对烹饪油烟引起的小鼠骨髓嗜多染红细胞微核率的影响。结果表明，烹饪油烟各实验组的小鼠骨髓嗜多染红细胞微核率明显高于阴性对照组（Ｐ〈０．０１），且呈现剂量－反应关系，剌玫果明显降低烹饪油烟诱发的微核率。     

d-宁烯、丹参及姜黄素衍生物对ras基因产物膜结合和细胞间隙信息传导的影响

目的旨在寻找新型抗肿瘤药物,进一步研究d-宁烯、丹参及姜黄素衍生物的抗肿瘤机理。采用分子生物学方法及划痕标记染料示踪技术,研究了4种人实体瘤起源的细胞系的细胞间隙信息传导(GJIC)、H-ras癌基因表达以及ras癌基因产物(P21^ras蛋白)表达状态,并观察了4种天然产物对它们的影响。结果表明,细胞内染料传输功能的丧失与ras基因突变率呈正相关;单萜化合物d-宁烯和酚类化合物丹参衍生物的抗肿瘤作用可能与抑制P21^ras蛋白膜结合和增强细胞间隙信息传导功能有关。提示Ras癌基因产物P21^ras蛋白膜结合的抑制与细胞间隙信息传导功能的增强有直接关系。     

西安市城市居民食管癌的病因研究:烟酒因素的作用

本文报道了1984年10月~1985年10月西安市城市居民138例食管癌的病例对照研究。结果表明,吸烟为食管癌发病的危险因素,OR_M-H为4.12(95% CI为1.57~6.54)。OR与吸烟量、吸烟年限有显著剂量效应关系。吸烟作为食管癌的可能致病因子其潜隐期为37.19年。饮酒与食管癌的联系不显著(χ²=1.03,P﹥0.05)。作者认为吸烟单独或与其它因素共同作用下可能参与食管的癌变过程。     

损伤性肝外胆管狭窄45例临床分析

目的：分析损伤性肝外胆管狭窄发生的原因和损伤后狭窄的修复术式选择。方法：损伤性肝外胆管狭窄45例，诊断方法以B超，PTC、ERCP为主，全组分别行胆管空肠吻合术，胆管十二指肠吻合术，肝门胆管整形术等手术治疗。结果：随访36例，末次手术行胆管空肠吻合术33例，优良87.9%。结论：可见性损伤和隐性损伤所致的瘢痕收缩是胆道狭窄的主要原因，损伤性肝外胆管狭窄的治疗方法以胆管空肠Y形吻合术较为理想。     

Post-transplantation diabetes is better controlled after conversion from prednisone to deflazacort: a prospective trial in renal transplants

It is well known that long-term use of steroids plays a decisive role in the development of glucose intolerance and diabetes mellitus (DM). Deflazacort, an oxazoline derivative of prednisolone, has been introduced as a potential substitute for conventional steroids in order to ameliorate glucose intolerance. We initiated a randomized study of conversion from prednisone to deflazacort in kidney transplantation (Tx) recipients presenting with pre-Tx or post-Tx DM to ascertain whether or not the switch to deflazacort would ameliorate the diabetic state. Forty-two recipients in the conversion group were compared with 40 patients on prednisone (the control group) in a prospective manner. The dose reduction of insulin or oral blood glucose-lowering agents, the adequacy of glucose control, and the development of side effects were the criteria for evaluating outcome. In the conversion group, patients were switched to deflazacort at a dose ratio of 6 mg deflazacort to 5 mg prednisone. During the mean follow-up period of 13.2 months, neither graft dysfunction nor acute rejection developed in the conversion group. Improvement in blood glucose control in the conversion group was noted. When the conversion group was stratified into pre- or post-Tx DM, promising effects were clearly evident in the post-Tx DM patients. More than 50 % dose reduction of blood glucose-lowering agents was possible in 42.3 % of post-Tx DM patients. In conclusion, it was readily possible to control blood glucose better in post-Tx DM recipients without seriously affecting the immunosuppressive activity after conversion to deflazacort.

关于单结合胆红素水溶性的研究

目的:进一步研究单结合胆红素(MCB)的水难溶特性及其在病理性胆汁中参与胆红素沉淀和色素性结石形成的作用机制.方法:应用胆红素高效液相色谱分析技术,先从人胆汁中获得结合胆红素,再经分离、制备及纯化得到纯MCB.然后观察其水溶解度并与其它型胆红素比较.结果:在pH7.9,温度37℃接近生理的条件下,MCB的溶解度(558.25±5.96μm)仅为双结合胆红素(DCB)的1/7,比不结合胆红素(UCB)高约44倍并随pH值改变而呈曲线变化.pH7.9时最大;pH4.5时为0;而当pH>9时,反而低于呈离于状态的UCB.结论:MCB虽作为结合型胆红素在胆道生理条件下的不溶性明显高于UCB,但比DCB要低得多;而在胆道病理条件下,其水溶性不但远低于DCB,甚至还不如离子化的UCB,这可能是MCB参与胆红素沉淀及胆色素结石形成的理化基础.     

脊髓Ⅱ号对大鼠损伤脊髓轴浆运输的影响

选取24只Wistar大白鼠，将其中18只制成胸髓右半侧横断损伤的大鼠模型，分别以脊髓Ⅱ号方剂、激素、生理盐水灌喂治疗。未造模的6只大鼠作为正常组，常规喂养。一个月后，注入辣根过氧化物酶（HRP），检测路经损伤区的上下行神经传导束始发核团中的标记细胞。发现脊髓Ⅱ号组HRP标记细胞数明显多于另两组，而与正常大鼠相比没有统计学上的显著差异。说明脊髓Ⅱ号方剂在恢复损伤传导来神经纤维的正常连续性，恢复神经元轴浆运输，促进神经细胞修复再生方面，有显著的效应。
