益气温阳活血方对急性心肌梗塞模型大鼠左室重构的影响

目的:观察益气温阳活血方对心肌梗塞模型大鼠左室重构的影响。方法:结扎冠脉前降支造模,治疗组益气温阳活血方灌胃,治疗第8周后检测各组大鼠心脏重量指数、左室壁面积、左室腔面积、左室腔周长等。结果:中药组心脏重量指数、左室壁面积、左室腔面积、和膨胀指数均较模型组下降(分别为P<0.05,P<0.01,P<0.05,P<0.01)。结论:益气温阳活血方具有良好的防治心室重构作用。     

地震灾害对分娩的影响

目的:观察地震灾害对分娩的影响。方法:对我院2008年5月12日至2008年6月12日在地震期间分娩的216例产妇进行回顾性分析。结果:阴道分娩率较地震前比较明显上升,剖宫产率明显下降。结论:地震灾害致孕妇的心理发生变化,导致阴道分娩率上升剖宫产率明显下降。     

免疫吸附治疗在肾移植致敏受者中的应用

目的：探讨蛋白A免疫吸附（immunoads Orption，IA）治疗对清除肾移植致敏受者体内特异性抗HLA抗体的疗效和安全性。方法：10例肾移植致敏（PRA〉50％）受者用彤新蛋白A免疫吸附柱行IA治疗，测定治疗前后血免疫球蛋白及PRA水平。结果：10例患者IA治疗次数为4～15次（中位数9）。所有患者IA治疗后血清总IgG水平都明显下降（P〈0．001），IgA和IgM也较治疗前显著降低（P〈0．01）。PRA8例转阴，1例〈30％，1例仍为100％。结论：对于肾移植致敏受者，IA是一种特异性高、安全有效的治疗措施。     

腹膜后脓肿的诊断和治疗

目的探讨腹膜后脓肿的病因,诊断和治疗。方法回顾性分析了1990-2004年诊断和治疗腹膜后脓肿33例的临床资料。结果急性坏死性胰腺炎后20例,胆囊切除胆总管探查术后4例,十二指肠损伤2例,阑尾穿孔3例,肾结石4例。超声检查确诊80%(20/25),CT检查确诊100%(22/22)。经腹部腹膜后脓肿切开置管引流25例,手术1~4次不等,后腰部切开引流8例。手术后并发应激性胃粘膜损伤致消化道出血7例,成人呼吸窘迫综合征(ARDS)5例,急性肾功能衰竭3例,死亡4例。治愈时间1~6个月,平均3.5个月。结论及时明确诊断,进行有效引流并加强营养支持是治疗成功的关键。     

Triptolide inhibits T cell activation and proliferation via multiple pathways

Triptolide is potent immunosuppressive has been reported to inhibit autoimmunity, compound isolated from Chinese herbal medicine. Triptolide allograft attributed to the suppression of T cells via NF - kB rejection and GVHD, and its efficacy was previously pathway and apoptosis. In the present study, we detailedly analyzed Triptolide＇ s function on murine primary T cell. We found that Triptolide could inhibit T cell activation and proliferation by dramatically down - regulating cell division and cell cycle. Triptolide inhibited T cell activation in a dose- dependent manner, and the inhibition was mediated by both NF- kB pathway and AP - 1 pathway.

A CASE OF EARLY GASTRIC CANCER ACCOMPANIED BY DIEULAFOY ULCER IN A YOUNG WOMAN

A case of early gastric carcinoma accompanied by Dieulafoy ulcer is presented. The patient, a 26‐year‐old female, visited our emergency room with chief complaints of massive hematemesis and tarry stool. The initial endoscopic examination revealed a superficial depressed lesion with a faded color accompanied by a tiny ulcer with converging folds at the anterior wall of the middle gastric body. Although no active bleeding vessel was found at that time, the patient was admitted to our hospital for further check‐ups and treatment. On the 6th hospital day, she developed massive hematemesis resulting in shock. Urgent endoscopy, this time, disclosed an exposed bleeding vessel at the small ulcer floor previously mentioned, and endoscopic hemostasis was achieved. Since, however, a biopsy at initial examination from the surrounding depressed area proved carcinoma, a partial distal gastrectomy was subsequently carried out. Histological examination of the resected specimen confirmed the diagnosis of carcinoma limited to the mucosa and submucosa along with findings consistent with Dieulafoy ulcer. This is a rare case of combination of early cancer and Dieulafoy ulcer particularly in such a young patient. A review of the literature is also presented.
