碱性成纤维细胞生长因子治疗猫急性脑梗死的作用机制研究

目的:观察碱性成纤维生长因子(bFGF)处理的缺血再灌注不同时程的猫脑组织中微管相关蛋白(MAP-2)和神经丝蛋白(NTP)的表达,探讨bFGF治疗缺血性脑损伤的可能作用机制。方法:健康家猫30只,随机分为生理盐水对照组和bFGF治疗组。采用左侧眼眶入路制作大脑中动脉缺血再灌注模型。于术前和再灌注24h、48h和7d,采用Philip的猫脑缺血神经功能评分标准进行神经功能缺损评分;应用免疫组织化学SP法检测缺血再灌注不同时程的脑组织MAP-2及NTP蛋白表达,进行免疫阳性细胞计数。结果:缺血再灌注48h后,治疗组动物神经功能受损程度较对照组明显减轻,MAP-2及NTP蛋白阳性细胞数目较对照组也显著增加。结论:bFGF通过诱导MAP-2及NTP蛋白的表达,减轻了缺血再灌注脑组织的神经元损伤和促进了神经纤维生长,从而改善受损的神经功能。     

可控性丝线留置术治疗体表难治性海绵状静脉畸形的实验及临床研究

目的研究可控性丝线的致栓效果及其治疗体表难治性海绵状静脉畸形的初步疗效。方法将丝线一端留置于不同管腔大小的静脉内,另一端挂于血管壁埋于皮下,实现其可控性,用经过不同处置的丝线,分别留置于兔耳缘静脉、股静脉,观察其引起血管栓塞的效果。选择致栓效果较好的丝线组,用于临床治疗难治性体表海绵状静脉畸形的患者。结果几种经不同处置的丝线,均能不同程度地起到闭塞血管的作用,对于管腔稍大,血流较快的静脉(兔股静脉),浸泡丝裂霉素并打结的丝线组,致栓效果最好;临床初步应用证实,可控性丝线治疗体表难治性静脉畸形,安全有效。结论可控性丝线静脉内留置术,是一种安全、有效、损伤小、操作简便的治疗体表难治性海绵状静脉畸形的新方法。

Month of birth and suicide: An exploratory study

OBJECTIVE: To explore the association between suicide and month of birth. METHOD: Data were extracted from records of the Public Health Department in North Cheshire between 1989 and 2000. &#164 Suicide' refers to all deceased who were the subjects of coroner's inquests resulting in a verdict of suicide or an open verdict. The month of birth of all who died of natural causes and were reported during a 2-year period was obtained from the Public Health Department in North Cheshire for comparison. RESULTS: There were 502 incidents of suicide in North Cheshire during the 12-year period. Significant differences were found between suicides and deaths due to natural causes, with an increase of incidents of suicide in those born in the month of May ( &#104 2 23, d.f.11, P < 0.01). The distribution of suicide by hanging appeared to be significantly higher in those born in September and July and lowest in those born in November compared with what would expected by chance ( &#104 2 28, d.f.11, P < 0.005). Those who died by violent means were more likely to have been born in the summer. The difference between the observed and expected numbers of suicides by methods other than hanging failed to reach statistical significance. CONCLUSION: The results, though inconclusive, are interesting, particularly in view of recent reports that persons born during the winter &#45 spring months had significantly lower values of 5-HIAA, and also reports of low CSF levels of 5-HIAA in persons with violent suicidal behaviour such as hanging, stabbing, firearms, or jumping from heights and impulsivity. A biological explanation of suicidal behaviour could have implications for our understanding of the psychopathology of suicide and eventually offer new strategies for treatment and prevention. The conflicting reports from different countries within the northern hemisphere indicate the need for future studies with adequate design and acceptable statistical power.     

Optimal asymmetric thread for orthodontic microimplants: Laboratory and clinical evaluation

Objectives:To investigate the performance of microimplants incorporating a newly designed asymmetric thread.Materials and Methods:Three microimplants were compared. The control group comprised microimplants with the original v-shaped thread. The two experimental groups (Taper 1.0 and Taper 1.25) comprised prototype microimplants constructed with the new asymmetric thread; the Taper 1.25 specimens had a 1.25-mm-long and sharper tip, while the Taper 1.0 and control groups had a less sharp 1-mm tip. Two specially designed artificial bone blocks mimicking soft (maxillary) and hard (mandibular) bone were used to evaluate the microimplant insertion characteristics and postinsertion lateral stability. The peak insertion torque, insertion time, Periotest value (PTV), and torsional strength were measured. Then the microimplants were evaluated clinically over a 3-month period.Results:Significant differences in peak insertion torque, insertion time, and PTV were observed and favored the experimental groups. Although statistically insignificant, the clinical success rate was also higher in the Taper 1.25 experimental group than in the control group (87.2% vs 75.6%).Conclusions:The better performances of the experimental microimplant, under both laboratory and clinical conditions (although statistically insignificant in the latter), demonstrate the superiority of the new asymmetric thread.
