人参总皂甙对不完全性脑缺血后海马CA1区NOS阳性神经元表达的影响

目的探讨人参总皂甙(GS)对不完全性脑缺血及再灌注不同时间后海马CA1区一氧化氮合酶(NOS)的影响及对神经元的保护作用.方法用双侧颈总动脉夹闭加放血的方法制成大鼠不完性脑缺血及再灌注模型,以还原烟酰胺腺嘌呤二核苷酸脱氢酶(NADPH-d)组织化学方法观察缺血及再灌注后海马CA1区NOS阳性神经元变化及GS对其的影响.结果单纯缺血组海马CA1区在缺血30min时NOS阳性细胞数最高(44.5±7.42),为假手术组2倍,再灌注2h、12h、24h、3d后逐渐下降,5d时恢复正常水平(21.12±3.50),缺血再灌注3d、5d时出现神经细胞损伤.GS能抑制缺血30min及再灌注各时程中NOS阳性神经元数量变化,并能预防缺血再灌注后迟发的神经元损害.结论GS对大鼠不完全性脑缺血及再灌注不同时程后海马CA1区NOS的异常表达有抑制作用,对神经元的保护作用.

妊娠妇女凝血-抗凝与纤溶测定的临床意义

目的：检测妊娠妇女和妊高征患者凝血与纤溶的变化，探讨孕妇在不同状态下各项指标的临床意义。方法：将63例妊娠妇女分为正常孕妇组43例和妊高征20例，采用磁珠凝固法检测凝血酶原时间(PT)、部分活化凝血酶时间(APTT)、凝血酶时间(TT)、纤维蛋白原(Fbg)和游离蛋白S(FPS)；免疫比浊法检测D-二聚体(D-D)、血管性血友病因子(vWF)，并与非孕妇的健康对照组作比较。结果：43例孕妇和20例妊高征患者血浆PT、APTT均显示不同程度的缩短；TT延长率在妊娠组仅为1％，而妊高征为18％；两组Fbg水平增高明显；妊娠组FPS与对照组比较差异无显著性，但妊高征患者表现明显降低；两组D-D水平均增高，且妊高征患者明显增高；妊娠组vWF水平与对照组比较尽管差异无显著性，但仍有3例高于对照组；妊高征患者增高率达100％。结论：妊娠妇女与妊高征患者均存在不同水平的凝血活化、纤溶亢进和内皮细胞一定程度的损伤，妊娠期作凝血-抗凝、纤溶指标的检测，对预防出血，降低DIC等的发生率具有指导意义。

Victim Help Seeking: Differences Between Intimate Terrorism and Situational Couple Violence

Abstract: Research indicates that two major forms of partner violence exist, intimate terrorism (IT) and situational couple violence (SCV). The current study (N= 389) used a subgroup of women who responded to the Chicago Women’s Health Risk Study to examine whether type of violence experienced is differentially related to formal (e.g., police, medical agencies, counseling) and informal (e.g., family, friends/neighbors) help seeking. IT victims were more likely to seek each type of formal help but were equally or less likely to seek informal help. Findings can inform both family violence research and the development and implementation of social service programs.     

Investigation of Direct Causes of Drug Relapse and Abstainers’ Demands in a Compulsive Detoxification Center in Wuhan City of China

Objective To identify the direct causes of drug relapse and abstainers’ demand, and to develop programs for the prevention of drug relapse. Methods Abstainers in a Compulsive Detoxification Center in Wuhan City, capital of Hubei Province were randomly selected. An investigation on the direct causes of drug relapse and abstainers’ demands was conducted with multiple-choice questionnaires and face to face interviews. Data were analyzed with SPSS 12.0. Results The direct causes leading to drug relapse included: temptation to use drug again by themselves or by their drug mates, seeking pleasure and ecstasy from drug use, relatively well off living, mental stress, irritation, demoralization, family conflicts, unemployment, feeling distrusted by the family, lack of care and love from the family, and discrimination by others. abstainers’ demands after detoxification and returning to the society included: care and support from the family, employment assistance, changing living environment, understanding by others, support from the society, and keeping far away from drugs. Conclusions Environmental factors are the direct causes of drug relapse, and negative irritation is its predisposing causes. Leaving former residence, more care and help given by both the family and the society and raising their overall quality of life are the demands of abstainers.
