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。     

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。     

输卵管卵巢脓肿的CT诊断价值

目的 总结分析女性输卵管卵巢脓肿的CT特征，以寻求和探讨鉴别诊断依据及CT诊断的价值。方法 回顾性分析10例输卵管卵巢脓肿患者CT腹盆腔增强扫描资料。结果 10例患者CT均显示附件区厚壁囊性或囊实混合性肿块，肿块外缘模糊毛糙，增强多见脓肿壁呈厚壁分层强化及内部强化分隔。其他伴随的CT表现：子宫骶骨韧带增厚9例，直肠周围、骶前脂肪密度增高模糊9例，显示输卵管扩张积脓或积液的管状结构影6例，宫腔积液4例。CT观察到脓肿与盆腔结构粘连包括：肿块与子宫粘连者9例，与直肠、乙状结肠粘连者4例，与盆腔小肠肠管及盆壁结构广泛粘连3例；显示腹膜增厚伴腹水及右侧输卵管卵巢脓肿伴阑尾炎各2例。结论 CT除了能观察附件区囊实性肿块，还能显示相邻盆腔器官的受累粘连及盆底软组织或筋膜层的炎性浸润，能对附件脓肿做定性和定位诊断，对诊断不清的可疑妇科感染有鉴别价值。

Severe odontogenic infections

Background : Severe odontogenic infections are serious potentially lethal conditions. Following the death of a patient in the authors' institution this study was initiated to determine the risk factors, management and outcome of a consecutive series of patients.
Methods : All patients admitted to the Royal Adelaide Hospital under the care of the Oral and Maxillofacial Surgery Unit with odontogenic infections in calendar year 2003 were investigated. Detailed information relative to their pre-presentation history, surgical and anaesthetic management and outcome was obtained and analysed.
Results : Forty-eight patients, 32M, 16F, average age 34.5, range 19 to 88 years were treated. All presented with pain and swelling, with 21 (44 per cent) having trismus. Forty-four (92 per cent) were as a result of dental neglect and four (8 per cent) were regular dental patients having endodontic treatment which failed. Of those known to have been treated prior to presentation, most had been on antibiotics. Most patients had aggressive surgical treatment with extraction, surgical drainage, high dose intravenous antibiotics and rehydration. The hospital stay was 3.3 (range 1–16) days. Patients requiring prolonged intubation and high dependency or intensive care (40 per cent) had longer hospitalization. No patient died and all fully recovered.
Conclusion : Severe odontogenic infections are a serious risk to the patient's health and life. Management is primarily surgical with skilled anaesthetic airway management. Antibiotics are required in high intravenous doses as an adjunct and not as a primary treatment.

目的:通过和冠脉造影对比,评价64排螺旋CT冠状动脉成像在冠状动脉狭窄中的临床应用价值。方法:28例患者同时行64排螺旋CT冠状动脉成像和有创性冠脉造影检查,依据AHA17段分段法,评价所有有效节段,并将两者进行对比。结果:冠脉造影显示阴性病例占7.1%(2例),单只病变占21.4%(6例),多支病变占71.4%(20例)。按节段分析,CT检出冠脉狭窄的敏感度,特异度,阳性预测值和阴性预测值分别为91.1%,94.6%,90.0和95.3%。结论:64排螺旋CT冠状动脉成像和传统的冠脉造影检查对检出正常冠脉节段以及狭窄节段具有很好的一致性。     

Development of a Simple Model of Extrinsic Denervation of the Small Bowel in Mouse

Small bowel transplantation (SBT) is associated with poorly understood enteric dysfunction. The study of SBT in mice is hindered by the technical difficulty of orthotopic SBT in the mouse. Our aim was to develop an easy preparation of extrinsic denervation of the entire jejunoileum in mice as a model of orthotopic SBT. All neurolymphatic tissues accompanying the superior mesenteric artery (SMA) and vein (SMV) were ligated just distal to the middle colic vessels. The SMA and SMV were then stripped of investing adventitia, and the mesentery to jejunum and colon were transected radially. Jejunum and colon were not transected and reanastomosed. To confirm extrinsic denervation 1, 3, and 6 months later, segments of small bowel were stained for protein gene product 9.5 (PGP9.5) and tyrosine hydroxylase (TH). Tyrosine hydroxylase immunoreactive intensity was then quantified using a semiquantitative analysis. Immunohistochemical fluorescence showed persistence of PGP9.5 immunoreactivity confirming enteric nerves in jejunoileum; however, there was no TH immunoreactivity in jejunoileum in denervated mice despite the expected preservation of TH immunoreactivity in the still-innervated duodenum at 1 month. At 3 months, sparse immunoreactivity for TH was present, and by 6 months, reinnervation of TH-containing nerves appeared similar to controls. Quantification of intensity at each time-point further confirmed this trend. This technique in the mouse accomplishes a complete extrinsic denervation of jejunoileum early postoperatively (1 and 3 months); reinnervation occurs by 6 months. This is an easily learned murine model of orthotopic SBT. Presented at the American Gastroenterological Association during Digestive Disease Week in Los Angeles, CA, as a poster presentation on May 23 2006.
