蝎蜂毒肽对大鼠纤溶系统作用初探

本研究采用大鼠肢体血管灌流和整体给药两种模型，观察蝎蜂毒（ＳＢＰ）对血管理灌流液内纤溶酶原激活物（ＰＡ）活性、血浆优球蛋白纤溶性（ＥＦＡ）和纤溶酶（ＰＬ）活性的影响。结果说明，ＳＢＰ有明显激活纤溶系统作用；其机制可能涉及血管内皮细胞释放ＰＡ活性增加，进一步促使纤溶酶原活化为ＰＬ增多的途径。     

复方真武冲剂对家兔实验性心力衰竭的血流动力学影响

目的观察中药复方真武冲剂(CZWG)对家兔实验性心力衰竭的血流动力学影响.方法结扎左冠状动脉前降支(LAD)方法复制家兔心力衰竭的实验模型.将家兔随机分为六组,采用左心室和股动脉插管术测定血流动力学指标 dp/dtmax、-dp/dtmax、LVEDP、SBP、DBP、MAP,针状电极记录二导联心电图.结果与假手术组比较,A组家免血流动力学发生显著异常;与A组相比,B组家兔 dp/dtmax、-dp/dtmax、LVEDP升高,LVEDP、HR降低,C组家兔有不同程度的改善,其中B组明显优于E组.结论CZWG能改善家兔实验性心力衰竭的血流动力学的异常,且CZWG中剂量作用明显.     

益气化痰活血法对血脂正常的高血压患者血管内皮功能的影响

目的:探讨益气化痰活血法对血脂正常的原发性高血压(Essential Hypertension,EH)患者血管内皮功能的影响。方法:218例EH患者按1∶1随机分为对照组和试验组。前者给予常规西医治疗,后者在常规治疗基础上加用益气化痰活血法。治疗30d,比较两组的临床效果、内皮依赖性血管舒张功能(Flow-mediated Vasodilation,FMD)和收缩压。结果:疗程结束时,试验组总有效率显著高于对照组(97.25%VS 86.24%,P0.05);试验组FMD显著高于对照组[(8.17±0.85)%VS(6.26±0.74)%,P0.05];试验组SBP明显低于对照组[(128.64±17.35)VS(134.72±19.57),P0.05]。结论:在常规西医治疗基础上加用益气化痰活血法能显著提高血脂正常EH患者的临床疗效,改善FMD和降低SBP。     

Mortality outcomes based on ED qSOFA score and HIV status in a developing low income country

Objective

To evaluate the utility of the quick Sepsis-related Organ Failure Assessment (qSOFA) score to predict risks for emergency department (ED) and hospital mortality among patients in a sub-Saharan Africa (SSA) setting.

Norfloxacin and cisapride combination decreases the incidence of spontaneous bacterial peritonitis in cirrhotic ascites

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a serious complication of cirrhosis with ascites, having high recurrence despite antibiotic prophylaxis. Small bowel dysmotility and bacterial overgrowth have been documented to be related to SBP. The purpose of the present paper was (i) to study whether addition of a prokinetic agent to norfloxacin ameliorates the development of SBP in high-risk patients; and (ii) to identify risk factors for SBP development. METHODS: A prospective, single blinded, randomized controlled trial was conducted in high-risk cirrhotic patients with ascites who had either recovered from an episode of SBP or who had low ascitic fluid protein. Norfloxacin 400 mg once daily (group I) or norfloxacin 400 mg once daily with cisapride 20 mg twice a day (group II) was given and occurrence of side-effects of therapy and mortality were recorded. RESULTS: Of the 94 patients, 48 (51%) were in group I, and 46 (49%) in group II. The actuarial probability of developing SBP at 12 month in group I was 56.8% and in group II, 21.7% (P = 0.026). Treatment failure was observed in five patients (10%) in group I and none in group II (P = 0.003). The actuarial probability of death at 18 months was 20.6% in group I and 6.2% in group II (P = 0.1). Low serum albumin, low ascitic fluid protein and alcoholic cirrhosis were related to development of SBP (P < 0.05). Additionally, low serum albumin (2.8 g/dL), gastrointestinal bleeding, alcoholic cirrhosis and low ascitic fluid protein were significantly associated with multiple occurrences of SBP. CONCLUSIONS: Prophylaxis with norfloxacin and cisapride significantly reduces the incidence of SBP in high-risk cirrhosis patients; low serum albumin, low ascitic fluid protein and alcoholic cirrhosis predispose to the development of SBP in high-risk cirrhosis patients; and low ascitic fluid protein should also be considered as a risk factor for the development of SBP requiring prophylaxis.
