Closure of left ventricle perforation with the use of muscular VSD occluder.

Growing experience in interventional cardiology leads to the use of large diameter of vascular equipment. In some instances, the so-called hybrid procedures are performed. After performing the interventional procedure, the opening in ventricular wall is closed surgically. Our intention was to check if the MVSDO can be used to close the perforation in the heart after the interventional cardiology procedure performed through the left ventricular (LV) free wall. In three pigs under general anesthesia, the heart was exposed through a small substernal incision. The LV was punctured and an 18F sheath was introduced into the LV. A 14 mm MVSDO was inserted through the 10F Delivery System. Using both the echocardiographic and angiographic guidance, the MVSDO was placed on the LV wall to close the opening in the LV. Time and volume of bleeding was recorded. In all cases the occluder was successfully placed closing the opening, bleeding observed after deployment of occluder lasted for approximately 2 min. We think MVSD occluder can be used to close the LV free wall perforation after hybrid interventional cardiac procedure. Early bleeding through MVSDO might be resolved by the manufacturing of new occluder with better sealing properties.     

Cisplatin-5-fluorouracil chemotherapy for advanced inoperable squamous carcinoma of the head and neck

Patients with locally advanced, inoperable squamous cell carcinoma of the head and neck were offered three courses of cisplatin and 96-h 5-fluorouracil (5-FU) infusion. Subsequent therapy included surgery when feasible, irradiation therapy, and a maintenance program of methotrexate (MTX)-5-FU. Thirty-three patients were evaluated prospectively. Seven patients underwent a single course of chemotherapy. Five patients underwent two courses of chemotherapy. Twenty-one patients underwent three courses of adjuvant chemotherapy. The overall response rate was 48% (16 of 33). Fifteen of 21 patients (76%) receiving three courses of chemotherapy evidenced a response; this included three complete responses (CRs) (9%). No responses were seen in patients receiving only one or two courses of chemotherapy. Among responding patients, the initial favorable response to chemotherapy was apparent after the first course of chemotherapy. Patients who failed to demonstrate any response after two courses of chemotherapy did not respond after a third course. A significant group of patients fail to respond and should be offered participation in other investigational protocols as they become available.     

The surgical risk of colectomy in patients with cirrhosis

The records of 54 patients with documented cirrhosis who underwent colectomy between January 1970 and January 1984 were studied to assess the operative risk and to determine the preoperative predictive risk factors. In-hospital mortality was 24 percent (13 patients), and postoperative complications occurred in 48 percent (26 patients). The risk of surgical intervention was significantly increased if encephalopathy, ascites, anemia, or hypoalbuminemia was present before operation. A simple operative risk index involving the presence of encephalopathy and ascites and the levels of hemoglobin and albumin is proposed to help distinguish a low-risk subgroup in whom postoperative mortality was 12.8 percent from a high-risk subgroup in whom postoperative mortality was 53.3 percent.     

上海市某区警察心理健康状况和生活质量的时点调查

目的调查警察心理健康状况和生命质量的基本流行学资料。方法采用梅奥心理服务问卷,主要内容为心理健康状况和生命质量测定等。在上海市某公安分局内进行截断面时点调查。结果1共调查警员1611人,男性91.5%,女性8.5%,年龄28.8±17.5岁。2GHQ的平均得分:1.5±2.31,存在可能心理障碍倾向者比例15.3%,可能存在重度心理障碍者比例2.9%。3SCL-90总分大于160分者比例17.2%;单项分大于2分比例最高的是强迫症状因子(19.5%),睡眠饮食因子次之(12.8%),躯体化症状因子(12.6%)第3位,敌对因子(12.4%)处于第4位。4健康变化、总体健康感、心理健康和生命活力得分是相对最低的维度。结论1在警察群体中存在心理障碍者比例远高于一般市民,生活质量一些维度相对较差;2建立长效机制是维护和保证警察心理健康和生活质量的有效手段。     

HPLC法测定盐酸美沙酮含量

本文采用高效液相色谱法，以盐酸布比卡因为内标，检测波长220nm，在Symmetry-C18柱上，以己腈-磷酸二氢钾（pH2．5）（3862，V／V）为流动相，测定盐酸美沙酮及其口服液的含量。方法平均回收率为100．17％，日内及日间的RSD均＜1％。方法简便、快速、准确。     

脑梗塞患者脑脊液中三种阿片肽含量变化

用放射免疫法对144例脑梗塞患者及24例对照者脑脊液中β—内啡肽(β—EP)、亮脑啡肽(LEK)、强啡肽A_(1-13)(D_(yn)A_(1-13))含量进行检测,结果显示脑梗塞急性期3天内β—EP、LEK含量较对照组显著增高.D_(yn)A_(1-13)较对照组显著降低,一周后逐渐接近或达到对照组水平。同时也发现基底节区脑梗塞患者脑脊液中β-EP、LEK较其它部位梗塞为高,D_(yn)A_(1-13)较其它部位梗塞为低,与对照组相比差异显著。提示脑脊液中二种阿片肽含量变化与脑梗塞时缺血性应激反应有关。三者不平衡变化,参与了急性脑梗塞时缺血性脑水肿等病理生理过程。也提示脑梗塞急性期(尤其3天内)适量应用阿片受体拮抗剂或激动剂,有利于减轻缺血性脑水肿,缓解神经受损症状。     

膀胱癌组织形态定量分析和病理学研究：附20例报告

对２０例膀胱移行上皮癌大切片ＨＥ染色，观察肿瘤表面、基部，浸润深部的组织形态特征，运用ＡｇＮＯＲ银染技术和图像分析技术进行了ＡｇＮＯＲ颗粒计数和核形态计量研究。结果表明：膀胱移行上皮癌表面组织与基部组织的分级和恶性程度无显著性差异。肿瘤浸润深部的组织分级与恶性程度比肿瘤表面组织的高。     

干下漏斗部室间隔缺损的外科治疗

４６例干下漏斗部室间隔缺损，占同期室缺手术治疗的２３．２％（４６／１９８）。缺损位于肺动脉瓣下３４例，漏斗部１２例。用带垫片褥式缝合修补２１例，补片修补２５例。全组无死亡。术后直接缝合组有主动脉关闭不全２例、残余分流２例，残留杂音３例。笔者认为，适时手术，选择适当的进路、应用补片修补、正确判断和处理主动脉瓣病变及对合并肺动脉狭窄者予以流出道补片加宽，是提高本病手术疗效的关键。     

婴儿肝炎综合征63例临床分析

对我科1989-1990年中收治的婴儿肝炎综合征63例的临床表现、合并症、治疗等方面进行了分析。笔者认为婴儿肝炎综合征为一组临床症候群。病因诊断有其重要性。腹部B超检查有助于肝炎和胆道闭锁的鉴别,可作为常规检查方法。并认为用肾上腺皮质激素治疗有效。
