参附养心汤对老年阳虚水泛型慢性心力衰竭患者心功能及血清IL-6、TNF-α、hs-CRP水平的影响

目的 观察参附养心汤治疗老年阳虚水泛型慢性心力衰竭的临床效果。方法 将老年阳虚水泛型慢性心力衰竭患者92例随机分为观察组和对照组,每组46例。对照组采用西医常规治疗,观察组在对照组治疗方法基础上给予参附养心汤治疗。治疗4周后,对两组患者临床疗效、脑钠肽（BNP）、6 min步行距离、心功能指标[左心室舒张末期容积（LVEDV）、收缩末期容积（LVESV）、左心室射血分数（LVEF）]及细胞炎性因子[白细胞介素-6（IL-6）、肿瘤坏死因子（TNF-α）、超敏C-反应蛋白（hs-CRP）]进行比较。结果 治疗4周后,观察组总有效率为89.1%,显著高于对照组71.7%,差异具有统计学意义（P<0.05）;观察组的BNP水平显著低于对照组,而6 min步行距离显著高于对照组,差异具有统计学意义（P<0.05）;观察组的LVEDV、LVESV均显著低于对照组,而LVEF高于对照组,差异具有统计学意义（P<0.05）;观察组的血清hs-CRP、IL-6及TNF-α水平均显著低于对照组,差异具有统计学意义（P<0.05）。结论 参附养心汤能显著改善老年阳虚水泛型慢性心力衰竭患者的心功能指标,降低BNP水平,减轻炎症反应,提高运动耐量,疗效显著。     

ASVCP guidelines: quality assurance for point‐of‐care testing in veterinary medicine

Point‐of‐care testing (POCT) refers to any laboratory testing performed outside the conventional reference laboratory and implies close proximity to patients. Instrumental POCT systems consist of small, handheld or benchtop analyzers. These have potential utility in many veterinary settings, including private clinics, academic veterinary medical centers, the community (eg, remote area veterinary medical teams), and for research applications in academia, government, and industry. Concern about the quality of veterinary in‐clinic testing has been expressed in published veterinary literature; however, little guidance focusing on POCT is available. Recognizing this void, the ASVCP formed a subcommittee in 2009 charged with developing quality assurance (QA) guidelines for veterinary POCT. Guidelines were developed through literature review and a consensus process. Major recommendations include (1) taking a formalized approach to POCT within the facility, (2) use of written policies, standard operating procedures, forms, and logs, (3) operator training, including periodic assessment of skills, (4) assessment of instrument analytical performance and use of both statistical quality control and external quality assessment programs, (5) use of properly established or validated reference intervals, (6) and ensuring accurate patient results reporting. Where possible, given instrument analytical performance, use of a validated 1_3s control rule for interpretation of control data is recommended. These guidelines are aimed at veterinarians and veterinary technicians seeking to improve management of POCT in their clinical or research setting, and address QA of small chemistry and hematology instruments. These guidelines are not intended to be all‐inclusive; rather, they provide a minimum standard for maintenance of POCT instruments in the veterinary setting.

还少丹对D-半乳糖衰老模型小鼠心肌线粒体DNA缺失的影响

目的探讨还少丹对D-半乳糖(D-gal)诱导的衰老小鼠心肌线粒体DNA(mtDNA)缺失的影响。方法将40只小鼠随机分为空白对照组、衰老模型组、还少丹低、高剂量组,用D-半乳糖建立衰老模型,分别给予蒸馏水和还少丹水煎液灌胃。连续给药6周后,采用聚合酶链反应(PCR)技术扩增心肌组织mtDNA,经琼脂糖凝胶电泳检测扩增条带,用光密度扫描定量各组mtDNA的缺失率。结果空白对照组未见mtDNA缺失型扩增条带,其余各组均出现不同程度的缺失型扩增条带;与模型组比较,低、高剂量组小鼠心肌mtDNA缺失率明显降低,差异均具有统计学意义(P<0.05);而低剂量与高剂量组之间比较mtDNA的缺失率差异无统计学意义(P>0.05)。结论还少丹能减少D-半乳糖诱导的衰老小鼠心肌mtDNA的缺失程度,提示该方能降低mtDNA的氧化损伤,保护mtDNA的结构完整性,从分子水平上为还少丹抗衰老的作用机制提供了一定的实验依据。 更多还原
