ΔNp63蛋白在膀胱移行上皮癌中的表达及其临床意义

目的 :探讨 p5 3基因家族新成员截短型p6 3(△Np6 3)在膀胱癌组织中的表达及其意义。 方法 :采用免疫组织化学SP法检测 4 0例膀胱移行上皮癌 (TCC)、6例膀胱内翻性乳头状瘤和 8例正常膀胱移行上皮中△Np6 3的表达 ,并分析△Np6 3表达与膀胱癌病理类型、临床分期的关系。 结果 :正常膀胱移行上皮、膀胱内翻性乳头状瘤、TCC中△Np6 3的阳性表达率分别为 37.5 % (3/ 8)、6 6 .7% (4/ 6 )、10 0 % (40 / 4 0 ) ,组间差异有统计学意义 (P <0 .0 1)。TCCG3 级与G2 级△Np6 3的强阳性、中度阳性表达率显著高于G1级 (P <0 .0 1)。Ta～T1期以△Np6 3弱阳性为主 (6 6 .7% ) ,随TCC浸润程度的增加 ,△Np6 3染色强度逐渐增强。T2 期△Np6 3强阳性表达率为 35 .3% ,T3 ～T4期增至 6 3.6 %。结论 :△Np6 3在TCC中高表达 ,与TCC病理分级、临床分期密切相关 ;△Np6 3可能参与TCC的发生、发展 ,是评估TCC预后的潜在因素之一。     

护士社会支持与焦虑状况相关因素调查分析

目的了解护士的社会支持与焦虑状况的相关因素,为心理干预提供理论依据.方法采用社会支持评定量表、状态焦虑量表(S-AT)对100名女护士进行调查,并分析其相关因素.结果护士社会支持评分为(37.22±6.94)分,S-AT评分(42.70±7.20)分;护士社会支持与焦虑状态呈负相关,即社会支持越高,焦虑状态越低;年龄<25岁、工龄<5年、未婚、合同护士社会支持明显偏低.结论良好的社会支持有助于减轻护士心理压力,是维护护士身心健康的重要因素.     

丁螺环酮和阿普唑仑治疗广泛性焦虑研究

目的：比较国产丁螺环酮和阿普唑仑治疗广泛性焦虑的疗效和不良反应。方法：对78例广泛性焦虑按照就医顺序分为两组，分别服用丁螺环酮(38例)和阿普唑仑(40例)。疗程6周。于治疗前及治疗第1、2、4、6周末进行汉密尔顿焦虑量表(HAMA)及副反应量表(TESS)评定疗效和不良反应。结果：丁螺环酮和阿普唑仑的疗效相仿，丁螺环酮的不良反应少且轻微，无过度镇静和肌肉松弛作用，不产生药物依赖。结论：丁螺环酮是治疗广泛性焦虑较为理想的药物。     

实施责任护士竞聘制的做法与成效

目的 :营造良性竞争的机制和氛围 ,全面提高护理质量。方法 :通过资格认定、理论技术考试、民主测评及双项选择 ,由护理部聘任。结果 :较好地进行了人力资源的开发 ,竞聘上岗后的护士有责任感和使命感 ,工作积极主动 ,自觉地成为科室各项工作的带头人。加之岗位工资的兑现 ,更有利于护士长在科室开展工作 ,使科室各项护理工作质量显著提高。结论 :良性的竞争运行机制 ,使优秀护理人才脱颖而出 ,体现能级对应的原则 ,从而使护理质量不断提高。     

Gaucher disease: abdominal MR imaging findings in 46 patients.

Abdominal magnetic resonance imaging findings were reviewed in 46 patients with Gaucher disease. All patients had hepatosplenomegaly at the time of initial imaging. Splenic nodules were present in 14 patients (30%) and varied in signal intensity. These nodules were isointense on T1-weighted and hypointense on T2-weighted images. Splenic infarcts were seen in 15 patients (33%), and four of these patients (9%) also had subcapsular fluid collections. Both nodules and infarcts were present in the spleen in four patients (9%). Pathologic correlation was performed with specimens from two patients who underwent partial splenectomy. Focal areas of abnormal signal intensity were noted in the liver in nine patients (20%). They were either stellate or segmental, and may represent fibrotic septa with ischemic changes associated with aggregates of Gaucher cells. No changes were noted in the kidneys or abdominal lymph nodes.

Outcome study: comparison of short-term vs long-term treatment in a residential community.

All patients admitted to a Residential Treatment Center (RTC), a drug-free hospital-based inpatient facility in February 1985 through July 1985, were followed-up 6 months after discharge. The results are contrasted with those obtained in 1973 in a similar follow-up study. Length of stay at RTC had been reduced from 1 year in 1973 to 3 months in 1985. Six months after discharge, the longer length of stay in 1973 appears to be almost twice as effective as the 3-month program in 1985.     

APPLICATION OF ACUPOINT-INJECTION THERAPY TO PAIN SYNDROME: CLINICAL ANALYSIS OF 250 CASES

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.     

Survival following hydrofluoric acid ingestion.

Systemic toxicity after significant dermal exposure to hydrofluoric acid includes rapid development of hypocalcemia and hyperkalemia, leading to ventricular fibrillation. Similar dysrhythmias have occurred in patients after ingestion of sodium fluoride-containing compounds. Ingestion of hydrofluoric acid could induce similar cardiac toxicity; however, reported cases of hydrofluoric acid ingestion rarely have been described, and the rapid death of these patients has not allowed verification of this hypothesis. On two separate occasions, a 70-year-old woman ingested up to 2 oz of a 8% hydrofluoric acid-containing solution. Recurrent ventricular fibrillation with concurrent hypocalcemia and hypomagnesemia complicated her first episode, whereas a more aggressive administration of calcium and magnesium may have prevented dysrhythmias in the second episode. Survival from ventricular fibrillation after hydrofluoric acid ingestion has not been reported previously and suggests a role for aggressive empiric calcium and magnesium replacement.
