糖心乐对糖尿病性心肌病大鼠血糖、血脂代谢的实验研究

目的:观察糖心乐(TXL)对糖尿病性心肌病(DCMP)大鼠血糖、血脂的影响。方法:SD大鼠随机分为正常对照组、模型对照组、达美康组及糖心乐大、小剂量组。将除正常对照组外的各组大鼠腹腔注射STZ建立糖尿病模型,造模后8w分别给予生理盐水、达美康、TXL大小剂量灌胃,连续4w,正常对照组不做处理。结果:与模型对照组比较,达美康组、糖心乐大、小剂量组大鼠的血糖、甘油三酯(TG)、总胆固醇(TC)显著降低(P<0.05,P<0.01),高密度脂蛋白(HDL-C)显著升高(P<0.05,P<0.01)。TXL大剂量组的降低血糖、TC,升高HDL-C作用与达美康组相当,降低TG作用优于达美康组(P<0.05)。结论:TXL可通过降低血糖、TG、TC水平,升高HDL-C水平来改善DCMP大鼠心肌的功能。     

改良后的家兔动脉深低温保存实验研究

目的：为探讨家兔动脉在改良的深低温保存后，其作为血管材料替代物的优越性。方法：无菌条件下取新鲜兔动脉，分别给予改良后的营养液经慢速深低温冷冻和快速深低温冷冻处理，6个月后异体和自体移植，12周后，取移植的血管组织，观测其组织活性，组织形态、血管通畅率。结果：改良的营养液保护的血管经慢冻法处理后与自体血管活性相近，经改良的营养液保护的血管，移植前后血管内膜的连续性，血管的组织结构良好；慢冻法处理的血管通畅率比速冻法处理的高，与自体移植组相当。结论：复方氨基酸可以替代传统冷冻保护液中的小牛血清用于血管的深低温保存，降低了该保存技术的成本；快速深低温冷冻保存的动脉血管活力移植效果不如慢速冷冻处理的异体动脉好。     

贲门失驰缓症介入治疗的疗效评价

目的：评价贲门失弛缓症球囊扩张介入治疗的疗效。方法：对20例贲门失驰缓症患者行球囊扩张术。结果：20例患者共进行了31次球囊扩张，人均1．5次（其中12例扩张1次，5例扩张2次，3例扩张3次）。术后患者吞咽困难明显缓解，主要并发症为疼痛和返流。术后随访无症状期为3－13个月。结论：球囊扩张术是治疗门失弛缓症的有效方法。     

护理记录缺陷分析及干预对策

目的 为了提高护理质量。方法 采用随机抽查500份护理记录的分析方法。结果 发现有种种缺陷118份（26．3％），共178例次。结论 以卫生部颁布的标准为准则，分析缺陷产生的原因，最后以人为本采取加强护士的法律知识学习，业务技术提升，质控队伍建设和医护、护护、护患关系沟通等措施，达到最大限度地减少护理缺陷，全面提高护理质量。     

前列腺癌新辅助治疗临床分析（附32例报告）

目的 总结32例前列腺癌患者新辅助治疗（NHT）的作用。方法 32例前列腺癌患者中药物去势17例，手术去势15例，并联合抗雄激素治疗3个月，统计NHT前后前列腺癌体积、肿瘤大小、PSA、FSH、LH和睾酮水平变化。结果 2组NHT后前列腺体积明显变小、肿瘤变小、变软，甚至消失，PSA和睾酮明显下降，药物去势组睾酮水平在耻骨后前列腺癌根治术（RRP）术后2～3个月可恢复正常，而手术去势组RRP术后睾酮呈持续低水平。结论 NHT可明显缩小前列腺体积，降低PSA，有利于手术操作。药物去势对内分泌影响是可逆的，而手术去势内分泌改变不可逆。     

Related factors of cognitive impairment after stroke

BACKGROUND: Cognitive impairment after stroke associates with various factors, such as age, educational years, etc. Besides concerning about the recovery of limb function after stroke, we should also focus on the rehabilitation of cognition. Moreover, we'd better pay attention to the control of all the risk factors of stroke, and improve the quality of life in stroke patients. OBJECTIVE: To analyze the factors that affect cognitive impairment after stroke. DESIGN: A related factors analysis. SETTINGS: Department of Neurology of Dalian Port Hospital and Dalian Second People's Hospital. PARTICIPANTS: Totally 148 stroke inpatients were selected from Department of Neurology, Dalian Port Hospital and Dalian Second People's Hospital from April 2004 to December 2005, including 100 males and 48 females, aging 45-75 years with an average age of (67±8) years; Their educational years ranged 2-10 years with an average of (6.1±3.7) years; The disease course ranged 15-30 days; All were right-handed. Inclusive criteria: All were accorded with the diagnostic standard set by the Fourth National Academic Meeting for Cerebrovascular Disease; Confirmed by CT or MRI; Informed consents were obtained from all the subjects. METHODS: After the disease conditions were stable, the patients were assessed with Wechsler memory scale (WMS) and Wisconsin card sorting test (WCST). WMS included forward and backward recitation of numbers and short-term memory (verbal memory, visual recognition). The number of times for correct and wrong classifications in WCST and the time to complete the trail making tests A and B were recorded. The focal volume, area and layer were recorded at 24 hours after admission. The general data of the patients were recorded, including name, sex, age, educational years, history of hypertension, history of diabetes mellitus. Electroencepalograph (EEG) was examined to record the wave shape, blood lipids were detected, and the cognition related indexes were analyzed with the Pearson correlation analysis. The correlation between cognitive indexes after stroke and the influencing factors were analyzed with multiple linear regression analysis. MAIN OUTCOME MEASURES: ① Correlation between cognitive indexes and imaging indexes; ② Influencing factors for cognitive indexes after stroke. RESULTS: All the 148 stroke patients were involved in the analysis of results. ① Correlation between cognitive indexes and CT indexes: There were obvious negative correlations between numerical symbol and focal layer (r =-0.234, P < 0.05), as well as between verbal memory and the focal area and volume (r =-0.363, -0.279, P < 0.05); Trail making test A had obvious positive correlation with focal area and volume (r =0.256, 0.256, P < 0.05). Results of multiple linear regression analysis: Correct classification was correlated with triglyceride (partial wave and θ wave (partial regression coefficient=0.231-0.908, P < 0.05); Verbal memory was correlated with EEG α wave, focal volume, sex, educational years and diabetes mellitus (partial regression coefficient=0.219-1.017, P < 0.05-0.01). Visual recognition had correlation with educational years and hypertension (partial regression coefficient=0.326, -1.163, P < 0.01). Trail making tests A and B were correlated with focal volume (partial regression coefficient=4.680, -18.561, P < 0.05). CONCLUSION: The factors that affect the cognitive function after stroke include sex, age, educational years, hypertension, diabetes mellitus, triglyceride, EEG wave shape, and the focal area, volume and layer
