代孕技术中的伦理道德及法律问题

新近发展的代孕技术给众多不孕夫妇带来为人父母的喜悦之时,也对人们传统的生殖伦理观念形成冲击并挑战现存法律制度.人们不仅要肯定代孕技术的合理性,也要警惕其所产生的潜在的破坏性影响.合理利用该技术和制定相应的法规是避免出现伦理和社会混乱的有效途径.     

前尿道代后尿道成形术治疗男性复杂性后尿道狭窄

目的探讨长段复杂性后尿道狭窄治疗新方法。方法采用分期前尿道代后尿道成形术治疗3例复杂性后尿道长段狭窄（6．5—10．0cm）患者。第一期行阴茎转位尿道端端吻合术，术后3—6个月行二期阴茎伸直、尿道会阴造口术，6个月后行第三期前尿道成形术（Johanson Ⅱ期尿道成形术）。结果例1术后排尿通畅，膀胱尿道造影检查示尿道通畅，双侧输尿管返流近消失，最大尿流率18．8ml／s，随访2年，最大尿流率18ml／s，无剩余尿。例2术后排尿通畅，最大尿流率19．5ml／s，无剩余尿，尿道扩张可顺利通过22F尿道探子。例3经会阴一耻骨联合径路行第一期阴茎转位尿道端端吻合术、尿道直肠瘘、尿道会阴瘘切除、修补术，术后尿道直肠瘘及尿道会阴瘘治愈，但因耻骨联合切口感染致吻合口狭窄，有待进一步治疗。结论分期前尿道代后尿道加前尿道重建方法是治疗男性长段复杂性尿道狭窄的有效方法。

脑梗塞合并精神障碍病人的分型及护理

脑梗塞是由于脑动脉粥样硬化和血栓形成使管腔闭塞，导致急性脑供血不足和脑组织局部坏死的临床症候群。其主要临床表现为偏瘫和失语。其中部分病人还可合并精神障碍。脑梗塞在我国十分常见，据文献报道：我国每年约有150余万人发生脑梗塞，因此认为做好脑梗塞病人的治疗和护理，尽快恢复其肢体和脑功能，具有十分重要的临床意义和社会意义。     

过量氟化物导致大鼠腰椎黄韧带退变与骨化

[目的]研究氟化物在黄韧带骨化中可能的作用机理。[方法]36只雄性SD大鼠，实验组饮用含NaF（质量分数为1014）蒸馏水，分别于3个月及6个月时，检测骨密度，血清、骨组织标本中Ca、P^3＋、Mg、Zn、Cu、Fe、F^-含量和血清碱性磷酸酶（ALP）活性；行大鼠腰段标本X线检查后组织病理观察。[结果]3个月实验组10只大鼠中6只出现氟斑牙：6个月实验组均出现氟斑牙，且大鼠中轴骨骨密度显著增加（P〈0．05）。X线检查，6个月实验组中有4只可见黄韧带嵴状骨化影。病理观察，3个月实验组大鼠黄韧带呈退行性改变；6个月实验组部分黄韧带骨化，骨化类型以膜内骨化为主。[结论]过量氟化物可造成SD大鼠腰椎黄韧带的退变、骨化，在黄韧带的骨化中可能起重要作用。     

Ruptured distal anterior choroidal artery aneurysm.

Ruptured aneurysms of the distal anterior choroidal artery (AchA) are extremely rare and management is dictated by clinical presentation. This report describes a rare patient with a distal AchA aneurysm and subarachnoid and intraventricular haemorrhage. A 60-year-old woman presented with a sudden onset of severe headache and vomiting. No aneurysms could be found on initial angiograms. A repeat angiogram performed 10 days after admission demonstrated an aneurysm in a branch of the cisternal segment of the left AchA without a definite neck. Surrounding vessels showed multifocal stricture and dilatation. Microsurgical clipping was not performed because the patient died suddenly due to pulmonary failure. The aetiology of the aneurysm in this case and surgical strategy are discussed.     

危重症患者的APACHEⅡ评分与中医辨证相关性研究

目的：通过比较不同中医证型的ICU危重症患者的APACHEⅡ评分，同时对比两组死亡率，评价中医辨证在预后判断中的临床意义。方法：对纳入研究的85例ICU危重症患者于入ICU及出ICU时分别进行中医辨证，分为阳类证和阴类证两型，对所有病人进行APACHEⅡ评分，比较两型病人在进入ICU及出ICU时的APACHEⅡ分值，并与死亡率比较。结果：初始为阴类证的患者在入ICU及出ICU时的APACHEⅡ评分显著高于初始为阳类证的患者（P=0．0001及F〈0．05），死亡率亦显著高于阳类证患者（P=0．0369）：治疗后由阳类证转为阴类证患者APACHEⅡ评分较维持阳类证者增高（P=0．0161），而阴类证转为阳类证的患者APACHEⅡ分值较维持阴类证者减低（P=0．0424）。结论：中医证型对危重症的病情程度及预后判断有较好的预测价值，阴类证患者的预后较阳类证患者差，证型转换可能引起预后改变。     

Cause-specific and total mortality in the Canterbury (New Zealand) insulin-treated Diabetic Registry population: a 15-year follow-up study.

AIMS: To establish all-cause and cause-specific death rates, and risk factors for mortality in insulin-treated diabetic individuals living in the province of Canterbury, New Zealand. METHODS: Insulin-treated diabetic subjects (n = 995) on the Canterbury Diabetes Registry were followed up over 15 years and vital status determined. Death rates were standardized and hazard regression was used to model the effects of demographic covariates on relative survival time. RESULTS: There were 419 deaths in 11 226.3 person-years of follow-up with a standardized mortality ratio (SMR) of 2.0 (95% confidence interval (CI) 1.8-2.2). Relative mortality was greatest for the group aged 0-29 years (SMR 3.0 (95% CI 2.4-3.7)). After controlling for diabetes duration and gender, a 10-year increment in age of onset was associated with a 33% decrease in relative hazard (95% CI 29-36%), indicating that excess mortality due to diabetes declines with rising age of onset. After controlling for age of onset and gender, each 10-year increment in duration of diabetes is associated with a 26% decrease in relative hazard (95% CI 24-29%), indicating that with longer survival the mortality hazard approaches the general population hazard. Relative mortalities were increased for cardiovascular, renal and respiratory disease, but not malignancy. Relative mortality from acute metabolic complications was increased in the subgroup with age of onset of diabetes < 30 years and requiring insulin within 1 year of diagnosis. CONCLUSIONS: Mortality rates are high for insulin-treated diabetic individuals relative to the general population.     

国产COSTANT冠状动脉支架治疗重症冠心病的远期疗效观察
