改良显微小梁切除术治疗葡萄膜炎继发性青光眼

Objective To investigate the effect of trabeculectomy combined with segmental iridectomy, mitomycin C (MMC) and viscoelastic agents usage on the treatment of glaucoma secondary in uveitis. Methods According to the age, degree of inflammation and the condition of Tenon capsule of patients, differ-ent concentration of MMC (0.25-0.33 mg/ml) was used during the operation, with separation of the anterior and posterior synechia, resection of pupillary organization membrane using viscoelastic agents. Segmental iridec-tomy and releasable sutures were also performed on the patients. The visual acuity of preoperation and postoper-ation, intraocular pressure, inflammation and the complication were record. Results Forty-two eyes of 38 cases with glaucoma secondary in uveitis were studied, the mean follow-up time was (12.01±3.56) months. The postoperative visual acuity improved in 14 eyes, didn't change in 28 eyes. The postoperative inflammation of anterior chamber disappeared in 35 eyes, relieved in 7 eyes. And the average postoperative intraocular pres-sure (15.20± 4.64) mmHg was significantly lower than the preoperative intraocular pressure (38.37±12.93) mmHg (t = 8.255, P = 0.000). The total success rate was 92.9%. There were no severe complication. Conclusion Trabeculeetomy combined with MMC, viscoelastic agents usage, separation of anterior and poste-rior syneehia, segmental iridectomy and releasable suture could increase the success rate of operation on pa tients with glaucoma secondary in uveitis, decrease the complication and inflammation reaction of operation, and the recurrence of uveitis.     

腹针治疗绝经前后诸症的临床研究

绝经前后诸症是一种40～50岁妇女最常见的病症。现代医学认为,卵巢功能衰退引起的雌激素下降为特征的内分泌紊乱,是绝经前后妇女月经紊乱、潮热、出汗、心悸、失眠等许多症状的根本原因。我科室采用腹针及电针对照治疗绝经前后诸症,效果较好,现总结汇报如下。     

抑郁症情绪面孔加工的大脑功能网络研究

研究抑郁症患者和正常人在不同的情绪认知任务下大脑功能网络是否存在差异.采用了相位同步的方法以衡量不同脑区间的连接强度,运用网络参数全局和局部效率来刻画大脑的小世界拓扑结构.选取16个抑郁症患者和14个正常被试进行正负情绪面孔搜索的认知任务,同时记录头皮脑电.选择低gamma (30 ～ 50 Hz)和高gamma (50～80 Hz)两个频段的数据建立相位同步矩阵.结果显示:抑郁症患者组的全局相位同步值高于正常组;低gamma频段网络成本区间在(0.25～0.50)内,高gamma频段网络成本区间为(0.25-0.55),情绪加工网络的全局和平均局部效率介于随机网络和规则网络之间,具有小世界特性;在高gamma频段,在最大效费差下(网络成本为0.3),全局效率值在组间有显著性差异,此时局部效率无显著性差异发现;在网络成本为0.5时,发现抑郁症组在左顶颞区和枕区的局部效率显著高于正常组,在情绪间未发现显著性差异.综上反映了抑郁症患者情绪加工网络的异常特性,为抑郁症患者神经网络机制的研究提供了一定的参考.     

食管鳞癌中VEGF-C、VEGF-D的表达与临床病理特征的相关性研究

目的 检测血管内皮生长因子-C、D(VEGF-C和VEGF-D)在食管鳞癌中的表达与各临床病理特征之间的关系,探索食管鳞癌淋巴结转移的机制.方法 免疫组化法检测VEGF-C、D在62例食管鳞癌根治术后标本及20例癌旁正常组织中的表达,计数微淋巴管密度(MLD).分析VEGF-C、D表达及MLD与临床病理特征之间的关系.结果 肿瘤组织中VEGF-C和VEGF-D的高表达率分别是74%(46/62)和82%(51/62);肿瘤边缘MLD(5.387±4.986)明显高于癌旁正常组织(1.900±2.245)(P<0.05).VEGF-C、D高表达组与低表达组相比,淋巴结转移更常见、临床分期也较晚,MLD增加与VEGF-C、D高表达、有淋巴结转移及临床分期较晚有关.VEGF-C和VEGF-D的表达有正相关关系(r=0.691,P<0.001).结论 VEGF-C和VEGF-D在食管鳞癌中可能通过增加肿瘤周边区域的淋巴管新生促进肿瘤的淋巴道转移.     

规范医院感染管理降低多药耐药菌传播

目的加强合理用药、标准预防和接触隔离预防的实施,降低多药耐药菌的感染与传播。方法根据规范要求制定医院感染管理相关制度、流程,运用选择式目标管理,要求多药耐药菌隔离率≥85.0%;手消毒剂使用合格率≥80.0%;手术预防用药时机达标率≥80.0%。结果经多药耐药菌隔离、手卫生、手术预防用药的目标管理,产超广谱β-内酰胺酶(ESBLs)肺炎克雷伯菌、ESBLs大肠埃希菌、耐甲氧西林金黄色葡萄球菌(MRSA)、耐甲氧西林凝固酶阴性葡萄球菌(MRSCN)的感染分别由2006年的55.4%、50.7%、81.6%和83.0%下降至2010年的26.5%、43.8%、65.9%和62.4%。结论合理使用抗菌药物,规范隔离预防措施的实施是降低多药耐药菌感染的有效手段。
