中国精神分裂症患者不同家庭干预措施效果比较的meta分析

目的对中国精神分裂症患者采取家庭干预的研究文献进行综合回顾和系统评价, 比较不同条件下家庭干预效果的差异。方法在中国知网、维普、万方、中国生物医学文献数据库四大中文数据库及OVID Medline、Science Direct、Web of Science、EBSCO四大英文数据库中, 检索各数据库建库至2015年1月为止使用社会功能缺陷筛选量表(SDSS)、简明精神病(科)量表(BPRS)、阳性与阴性症状量表(PANSS)研究中国精神分裂症患者家庭干预效果的文献, 以标准化加权均数差( SMD)作为效应量, 采用meta分析比较不同干预时间、不同干预类型、对不同病程和不同严重程度的精神分裂症患者的家庭干预效果差异。 结果共纳入57篇符合标准的文献。SDSS、PANSS分析结果显示:① 干预时间越长干预效果越好( P < 0.0001、 P=0.0025);② 单独家庭干预比多个家庭合并单独家庭干预的效果更明显( P < 0.0001、 P=0.0131);③ 干预对于病情较重患者效果较好( P < 0.0001、 P=0.0280)。SDSS量表还显示家庭干预对于病程短的患者效果更好( P < 0.0001)。 结论家庭干预更适合病程较短的精神分裂症患者, 干预应实施较长时间; 单独家庭干预更有利于患者阴性症状的改善和社会功能的康复, 且对于病情较轻患者的阴性症状改善效果更好。     

人格特征对男性喉鳞状细胞癌患者术后近期心理状况的影响

目的 探讨人格特征对喉鳞状细胞癌（LSCC）患者术后近期心理健康状况的影响。方法 纳入2017年1月—2019年12月在湖北省肿瘤医院行手术治疗的119例男性LSCC患者，术后5~7 d采用SCL-90、SAS、SDS自评量表评估术后心理状态，采用EPQ问卷测评患者的人格特征。多元线性逐步回归方法分析LSCC患者术后近期SAS和SDS评分的影响因素。结果 男性LSCC患者术后SCL-90、SAS、SDS得分显著高于中国常模（P≤0.05），EPQ中精神质（P）量表和神经质（N）量表得分高于中国常模（P<0.01）。男性LSCC患者术后躯体化、强迫、焦虑、抑郁、敌对、恐怖、偏执、精神病性因子得分均显著高于中国常模（P<0.05）。家庭收入、手术方式、术后近期是否行放化疗、P和N人格特征是术后SAS评分的影响因素（均P<0.01）；家庭收入、手术方式、术后近期是否行放化疗和N人格特征是术后SDS评分的影响因素（P<0.01）。结论 LSCC患者术后近期存在抑郁、焦虑等心理障碍；具有P和N人格特征；家庭收入、手术方式、术后近期是否行放化疗以及P和N人格特征是影响术后SAS及SDS评分的独立危险因素。     

The use of cadaver models to diagnose rib fractures: A pilot study

Background

In the emergency department, rib fractures are a common finding in patients who sustain chest trauma. Rib fractures may be a sign of significant, underlying pathology, especially in the elderly patients where rib fractures are associated with significant morbidity and mortality. To date, no studies have evaluated the ability of ultrasound to detect rib fractures using cadaver models and subsequently use this model as a teaching tool.

从形气神谈溃疡性结肠炎的中西医认识

溃疡性结肠炎(Ulcerative colitis,UC)是一种病情反复、迁延难愈的炎症肠病,已被世界卫生组织列为现代难治病之一[1]。本病病因及发病机制尚不明确,西药治疗效果欠佳。近年来中医药的介入,临床取得显著疗效。西医学认为疾病是机体在一定致病因素的作用下自稳调节紊乱,经过机体内损伤和抗损伤反应的相互斗争,表现出的一系列功能。     

谷氨酸对腺苷A2A受体调节一氧化氮合酶活力的影响

目的探讨谷氨酸是否能够影响腺苷A2A受体对一氧化氮合酶（NOS）活力的调节。方法用1000ng／ml脂多糖（LPS）刺激小胶质细胞，分别加入100nmol／L A2A受体激动剂CGS21680以及不同浓度的谷氨酸（0，1，0，25，0，5mmol／L）干预，观察NOS活力变化。结果LPS诱导NOS活力增高，激活A2A受体可以产生抑制作用；0，25及0．5mmoL／L谷氨酸和A2A受体激动剂同时存在时，NOS活力进一步增高。结论高浓度谷氨酸可逆转腺苷A2A受体激动剂抑制升高NOS活力的作用。

Nocardia infection in lung transplant recipients.

BACKGROUND: Nocardia is responsible for infection in both normal and immunocompromised hosts. Organ transplant recipients are increasingly recognized as a sub-group of immunocompromised patients in whom nocardia is an important pathogen. The frequency of nocardia in organ transplant recipients varies between 0.7% and 3%. Nocardia infection has largely been reported in heart, kidney and liver transplant recipients. Presentations of nocardia in lung transplant recipients have been restricted primarily to case reports. The present study reviews the clinical and epidemiologic characteristics of nocardia infection in lung transplant recipients at our institution. METHODS: A retrospective cohort study of 473 lung transplant recipients from January 1991 to November 2000 was done at a university hospital. Patient demographics, immunosuppressive regimen at the time of isolation of nocardia species, use of trimethoprim-sulfamethoxazole for Pneumocystis carinii prophylaxis, rejection episodes in the preceding 6 months, concurrent pathogens, site of infection, radiologic findings and treatment and outcome were recorded. RESULTS: Nocardia infection was found in 2.1% (10 of 473) of our lung transplant recipients. Median time of onset was 34.1 months after transplantation. Nocardia species included N farcinica in 30% (3 of 10), N nova in 30% (3 of 10), N asteroides complex in 30% (3 of 10) and N brasiliensis in 10% (1 of 10) of patients. Post-transplant diabetes was present in 50% (5 of 10) of patients. The primary indication for lung transplantation was emphysema in 40% (4 of 10). Native lung involvement was noted in 75% (3 of 4) of patients with single lung transplant. Breakthrough nocardia infection were noted in 6 patients who were receiving trimethoprim-sulfamethoxazole prophylaxis for P carinii pneumonia; all breakthrough isolates remained susceptible to trimethoprim-sulfamethoxazole. Overall mortality was 40% (4 of 10). All patients (3 of 3) with infection due to N farcinica, except 1 (1 of 7) with infection due to other nocardia species, died. Seventy-five percent (3 of 4) of deaths were attributable to nocardia infection. CONCLUSIONS: Nocardia infection tended to involve the native lung in single lung transplant recipients. Trimethoprim-sulfamethoxazole for P carinii prophylaxis at the doses given was not protective against nocardiosis in these patients. Infection with N farcinica was associated with poor outcome. Thus, species identification and extended courses of antibiotics based on antimicrobial susceptibility testing are important in management of these patients.     

Pituitary abnormalities in eating disorders: further evidence from MRI studies

1. The frequent occurrence of hypothalamo-pituitary dysfunction in patients with eating disorders as well as prior reports that nutritional and endocrine status influence pituitary morphology, led us to hypothesize that pituitary size and shape may be altered in patients with eating disorders. 2. Magnetic resonance imaging (MRI) does not use ionizing radiation and is currently one of the most feasible modalities available to study the pituitary gland in vivo. Using MRI, we have previously reported in a preliminary study that female patients with eating disorders had significantly smaller pituitary glands than controls. In addition MRI excluded any pituitary mass lesions. 3. In this report, we confirm our previous MRI findings and provide further evidence of pituitary abnormalities in an expanded sample of eating disorder patients. Preliminary data on pituitary volume estimates from MRI scans are provided for a subset of patients and controls.
