认知行为干预对乳腺癌外科手术患者认知水平、自护能力及心理状态的影响

目的 探讨认知行为干预对乳腺癌外科手术患者认知水平、自护能力及心理状态的影响.方法 选择2018年6月至2020年6月我院进行乳腺癌外科手术的50例患者作为研究对象,按照护理模式将其分为对照组和观察组,各25例.对照组给予常规护理干预,观察组在对照组的基础上采用认知行为干预.比较两组的干预效果.结果 干预后,观察组的认...     

丙谷胺对急性胰腺炎大鼠的治疗作用

观察CCK受体拮抗剂丙谷胺对急性胰腺炎(AP)大鼠治疗作用。应用胰胆管内注射5％牛磺胆酸钠溶液诱发大鼠急性胰腺炎模型,术后腹腔内注射丙谷胺溶液(剂量400mg/kg);观察术后6h各组腹水量、胰重、血清脂肪酶活性和病理变化,计算大鼠24h内死亡率。丙谷胺治疗组鼠腹水量、胰重、脂肪酶活性分别为2.04±0.39(g)、1.57±0.38(g)、577.97±8.38(U),均显著低于非治疗组(9.34±2.04、2.04±0.39、715.38±44.76),P<0.05;鼠死亡率由非治疗组的100％降至40％;病理损害程度减轻。丙谷胺对牛磺胆酸钠诱发的大鼠急性胰腺炎有一定治疗作用。     

False positive reactions in confirmatory tests for syphilis in presence of antiphospholipid antibodies: misdiagnosis with prognostic and social consequences

False-positive reactions in the Venereal Disease Research Laboratory test are well known, whereas a positive fluorescent treponemal antibody absorption assay is rarely thought to be a false positive. The non-recognition of serological false-positive tests for syphilis may have negative prognostic and social implications.     

Comprehensive review into the challenges of gastrointestinal tumors in the Gulf and Levant countries

Although gastrointestinal stromal tumors(GISTs)are rare,with an incidence of 1/100000 per year,they are the most common sarcomas in the peritoneal cavity.Despite considerable progress in the diagnosis and treatment of GIST,about half of all patients are estimated to experience recurrence.With only two drugs,sunitinib and regorafenib,approved by the Food and Drug Administration,selecting treatment options after imatinib failure and coordinating multidisciplinary care remain challenging.In addition,physicians across the Middle East face some additional and unique challenges such as lack of published local data from clinical trials,national disease registries and regional scientific research,limited access to treatment,lack of standardization of care,and limited access to mutational analysis.Although global guidelines set a framework for the management of GIST,there are no standard local guidelines to guide clinical practice in a resource-limited environment.Therefore,a group of 11 experienced medical oncologists from across the Gulf and Levant region,part of the Rare Tumors Gastrointestinal Group,met over a period of one year to conduct a narrative review of the management of GIST and to describe regional challenges and gaps in patient management as an essential step to proposing local clinical practice recommendations.     

ELISA法检测不育男子精浆中抗人精浆免疫抑制因子IgG和IgA

本文首次建立了抗人精浆免疫抑制因子（ＳＰＩＦ）ＩｇＧ和ＩｇＡ的ＥＬＩＳＡ测定法，用其对５０例生育男子和１００例不育男子精浆中抗ＳＰＩＦＩｇＧ和ＩｇＡ进行了测定。结果显示：精浆中抗ＳＰＩＦＩｇＧ和ＩｇＡ的阳性率在生育男子分别为６％和４％；在不育男子分别为３４％和２８％。不育组抗ＳＰＩＦＩｇＧ和ＩｇＡ阳性率均显著高于生育组（Ｐ＜０．０１）。本文就抗ＳＰＩＦＩｇＧ和ＩｇＡ在抗生育及生殖道感染方面的可能作用进行了讨论。
