激素敏感型肾病单个核细胞培养上清液对大鼠肾小球多阴离子及超微结构的影响

用刀豆蛋白Ａ刺激激素敏感型肾病单个核细胞，并将其培养上清液灌注于大鼠肾内。结合电镜观察，用图像分析仪及体视学方法分别对其肾组织胶体铁染色切片和电镜照片上的足突和滤过裂隙的平均宽度进行测定。结果表明：该病极期上清液灌注的鼠肾小球多阴离子明显减少，足突肿胀、融合，滤过裂隙变窄；而该病缓解组和正常对照组则为阴性。说明该病单个核细胞培养上清液可引起鼠肾小球微小病变型肾病综合征的病变，并揭示该变化可能是由其上清液中一种异常的Ｔ淋巴细胞因子所致。

马桑内酯所致癫痫发作大鼠红细胞免疫粘附功能的研究

作者用红细胞Ｃ＿３ｂ受体花环试验和红细胞免疫复合物花环试验对马桑内酯所致癫痫发作大鼠红细胞免疫粘附功能的变化进行了观察，结果表明，癫痫组动物红细胞Ｃ＿３ｂ受体花环率明显低于对照组，而红细胞免疫复合物花环率相差不显著．提示癫痫发作可导致大鼠红细胞免疫粘附功能降低，因此在癫痫治疗中注意调整和增强患者的红细胞免疫功能具有重要意义。     

对－苯二甲酸衍生物的合成及其诱导分化HL－60细胞的活性

作者合成了１３个对－苯二甲酸衍生物，其中有９个化合物尚未见文献报道。通过对ＨＬ－６０细胞诱导分化活性试验，发现有两个化合物在浓度为５×１０￣（－６）ｍｏｌ／Ｌ时，可使细胞分化率达５５％，低于维Ａ酸的分化率（７９％，１０￣（－７）ｍｏｌ／Ｌ）。     

赖型钩端螺旋体重组DNApCX7的特异性鉴定和限制性内切酶谱分析

本实验将赖型钩端螺旋体（简称钩体）ＤＮＡ基因库的克隆ｐＣＸ７制备成￣（３２）Ｐ－重组ＤＮＡ探针，对８个不同血清群的１７株问号状钩体、双曲钩体ＰａｔｏｃⅠ株以及细螺旋体３０５５株ＤＮＡ进行打点杂交；同时用１５种ＤＮＡ片断进行限制性内切酶谱分析。结果表明，该重组ＤＮＡ具有问号状钩体种（Ｓｐｅｃｉｅｓ）特异性，但与不同问号状钩体之间的同源性程度有差别；限制性内切酶谱分析发现ｐＣＸ７重组ＤＮＡ片段长约１．７ｋｂ，具有１个Ｂｇ１Ⅱ识别位点和３个ＢｓｔＢ１识别位点。     

大鼠子宫内膜抗菌成分的初步分析

作者以１％乙酸冲洗ＳＤ大鼠子宫内膜，获得子宫内膜酸溶性提取物。利用琼脂糖弥散法和电泳凝胶琼脂糖弥散法抗菌试验发现，子宫内膜提取物有三条主蛋白带对致病性大肠杆菌ＭＬ－３５Ｐ耐药株有强抗菌活性，这三条抗菌蛋白带命名为ＲａｔＵＰ－１，ＲａｔＵＰ－２和ＲａｔＵＰ－３，分别占子宫内膜提取物总蛋白量的４．５％，５．７％和６．６％。虽然提取物存在溶菌的活性，但其含量甚微，在ＡＵ一ＰＡＧＥ图谱上亦未能显现溶菌酶条带。本实验的结果提示子宫内膜合成一类抗菌多肽，可能在子宫抗菌机制中发挥重要作用。     

5-HT 102T/C多态性与Tourette综合征的病例对照及核心家系关联分析

目的 研究5－羟色胺受体102T／C多态性是否与Tourette综合征（TS）相关联,方法对157个核心家系样本采用病例－对照关联分析,传递不平衡检验方法,聚合酶链反应及RFLP等技术,根据TS与强迫症（obsessive compulsive disorder,OCD)的同病现象,将TS划分亚组进行与5－羟色胺受体102T／C多态性的关联分析。结果 合并OCD的TS与该位点的基因型102C／C（X2＝8．38,P＝0．004）及等位基因102C／（X2＝4．84,P＝0．028）存在关联,进一步采用传递不平衡分析,发现合并（美国精神疾病诊断和统计手册IV》论断标准的OCD的TS与该位点存在关联或连锁不平衡（X2＝5．12,,P＝0．02）,而在TS总体样本及单纯TS样本中未发现与该位点的关联,结论 5－羟色胺受体102T／C多态性与中国人群合并OCD的TS存在关联,合并OCD的TS可能是TS中相对独立的一个亚型。     

(Em)placing recovery: Sites of health and wellness for individuals with serious mental illness in supported housing

This study used photo-elicitation methodology to explore how the move from supervised to supported housing affects recovery and community connections for individuals living with serious mental illness (SMI) in four Canadian cities. Qualitative interviews conducted in 2015 revealed five themes: (1) the characteristics distinguishing home from housing; (2) the importance of amenities offered by supported housing; (3) the connections between accessibility, mobility, and wellbeing; (4) the role of certain places in facilitating aspects of recovery such as offering hope or facilitating social connectedness; and (5) the concrete and metaphorical impact of changing vantage points on identity (re)construction. Utilizing therapeutic landscapes as an analytical framework, and combining insights from the health geography, and mental health (MH) housing and recovery literatures, this study deepens current understanding of how everyday places—conceptualized as therapeutic landscapes—directly and indirectly support MH recovery for individuals with SMI. Implications for research on housing, and on the spatial aspects of recovery processes are discussed.     

Improving masticatory performance,bite force,nutritional state and patient's satisfaction with implant overdentures: a systematic review of the literature

Oral function with removable dentures is improved when dental implants are used for support. A variety of methods is used to measure change in masticatory performance, bite force, patient's satisfaction and nutritional state. A systematic review describing the outcome of the various methods to assess patients' appreciation has not been reported. The objective is to systematically review the literature on the possible methods to measure change in masticatory performance, bite force, patient's satisfaction and nutritional state of patients with removable dentures and to describe the outcome of these. Medline, Embase and The Cochrane Central Register of Controlled Trials were searched (last search July 1, 2014). The search was completed by hand to identify eligible studies. Two reviewers independently assessed the articles. Articles should be written in English. Study design should be prospective. The outcome should be any assessment of function/satisfaction before and at least 1 year after treatment. Study population should consist of fully edentulous subjects. Treatment should be placement of any kind of root‐form implant(s) to support a mandibular and/or maxillary overdenture. Fifty‐three of 920 found articles fulfilled the inclusion criteria. A variety of methods was used to measure oral function; mostly follow‐up was 1 year. Most studies included mandibular overdentures, three studies included maxillary overdentures. Implant‐supported dentures were accompanied by high patient's satisfaction with regard to denture comfort, but this high satisfaction was not always accompanied by improvement in general quality of life (QoL) and/or health‐related QoL. Bite force improved, masseter thickness increased and muscle activity in rest decreased. Patients could chew better and eat more tough foods. No changes were seen in dietary intake, BMI and blood markers. Improvements reported after 1 year apparently decreased slightly with time, at least on the long run. Treating complete denture wearers with implants to support their denture improves their chewing efficiency, increases maximum bite force and clearly improves satisfaction. The effect on QoL is uncertain, and there is no effect on nutritional state.
