温病学理论指导下的新型冠状病毒肺炎诊治刍议

基于温病学理论,探讨新型冠状病毒肺炎的中医病因病机与诊治思路。温病学说源于明清之前的历代中医理论积累,经过长期的温热病防治实践而形成,其对于外感热病(包括烈性传染病)的病因病机、证治方药有着较为系统的论述,近年来在我国的新发传染病防治中发挥出积极的作用。温瘟相通,瘟疫病因多为热毒疫邪,表现为热证阳证,可按温病学中的卫气营血或三焦辨证分期论治,或治以吴又可、庞安时等的经方验方,这些因、机、证、治理论可试用于新型冠状病毒肺炎的中医诊疗。且肺与大肠相表里,胃肠道也是新型冠状病毒侵袭或繁殖的部位,采用中医清热通下之法,使邪从肠道而出,可能是减轻体内病毒感染与肺脏炎症的一种途径。     

化瘀汤治疗脑卒中疗效观察及对神经功能缺损康复的影响

目的:观察化瘀汤治疗脑卒中临床疗效及其对患者神经能缺损康复的影响。方法:将风痰瘀阻型缺血性脑卒中80例随机分为2组,每组40例;对照组采用西医常规治疗,观察组在对照组的基础上加用化瘀汤治疗,2组疗程均为21天;观察比较2组临床疗效、美国国立卫生研究院卒中量表(NIHSS)评分、Fugl-Meyer评分、中医证候积分。结果:总有效率观察组为95.0%,对照组为80.0%,2组比较,差异有统计学意义(P<0.05)。治疗后,2组患者NIHSS评分较治疗前明显下降(P<0.05),Fugl-Meyer评分明显升高(P<0.05);且观察组两项评分改善较对照组更显著(P<0.05)。治疗后,2组中医主症、次症积分均较治疗前明显降低(P<0.05),且观察组两项积分均明显低于对照组(P<0.05)。治疗后,2组患者SS-QOL评分均较治疗前明显升高(P<0.05),且观察组SS-QOL评分明显高于对照组(P<0.05)。结论:在西医常规治疗的基础上,加用化瘀汤治疗风痰瘀阻型缺血型脑卒中患者,能显著改善患者神经功能、肢体运动功能及生活质量,缓解临床症状,疗效优于单纯西医治疗。     

活血利水法在骨伤科疾病中的应用

基于骨伤疾病瘀血内阻的重要病机和现代医家"治血重治水"的学术观点,探索概括了活血利水法在骨伤疾病中的应用现状,结合现代医学的认识,全方位分析了活血利水法的优势和缺点。活血利水法可应用于骨折、筋伤等骨伤科大部分疾病及骨伤科疾病的围手术期,能改善肢体肿胀,促进伤口愈合,便于患者早期功能康复,但目前的临床应用尚缺乏统一的规范和标准,且处方不良反应尚未完全阐明。

Hepatic Artery Anatomic Variations and Reconstruction in Liver Grafts Procured in Greece: The Effect on Hepatic Artery Thrombosis

Aims

Variations of the anatomy of donor hepatic arteries increase the number of arterial anastomoses during liver transplantation and, possibly, the incidence of hepatic artery thrombosis (HAT). In this study, we describe the arterial anatomic variations in liver grafts procured and transplanted by a single center in Greece, the techniques of arterial anastomosis, and their effect on the incidence of early HAT.

The Importance of Venous Return in Starling‐Like Control of Rotary Ventricular Assist Devices

Rotary ventricular assist devices (VADs) are less sensitive to preload than the healthy heart, resulting in inadequate flow regulation in response to changes in patient cardiac demand. Starling‐like physiological controllers (SLCs) have been developed to automatically regulate VAD flow based on ventricular preload. An SLC consists of a cardiac response curve (CRC) which imposes a nonlinear relationship between VAD flow and ventricular preload, and a venous return line (VRL) which determines the return path of the controller. This study investigates the importance of a physiological VRL in SLC of dual rotary blood pumps for biventricular support. Two experiments were conducted on a physical mock circulation loop (MCL); the first compared an SLC with an angled physiological VRL (SLC‐P) against an SLC with a vertical VRL (SLC‐V). The second experiment quantified the benefit of a dynamic VRL, represented by a series of specific VRLs, which could adapt to different circulatory states including changes in pulmonary (PVR) and systemic (SVR) vascular resistance versus a fixed physiological VRL which was calculated at rest. In both sets of experiments, the transient controller responses were evaluated through reductions in preload caused by the removal of fluid from the MCL. The SLC‐P produced no overshoot or oscillations following step changes in preload, whereas SLC‐V produced 0.4 L/min (12.5%) overshoot for both left and right VADs. Additionally, the SLC‐V had increased settling time and reduced controller stability as evidenced by transient controller oscillations. The transient results comparing the specific and standard VRLs demonstrated that specific VRL rise times were improved by between 1.2 and 4.7 s ( = 3.05 s), while specific VRL settling times were improved by between 2.8 and 16.1 seconds ( = 8.38 s) over the standard VRL. This suggests only a minor improvement in controller response time from a dynamic VRL compared to the fixed VRL. These results indicate that the use of a fixed physiologically representative VRL is adequate over a wide variety of physiological conditions.     

Fertility Outcome After Renal Transplantation: A Single-Center Experience

BackgroundWomen suffering from kidney disease are more prone to fertility problems, due to uremia. Fortunately, their fertility rate increases dramatically after renal transplantation. This study analyzes the predictors/risk factors of successful pregnancy with live birth outcome while presenting an overview of the 7-year experience of a single center.MethodsThis retrospective cohort study includes 239 women of reproductive age (18–40 years) who underwent renal transplantation in a tertiary Turkish clinic between October 1, 2011, and August 24, 2017. The subjects were invited to take part in a survey questioning their obstetric characteristics and they were assessed in 2 groups: fertile and infertile. Multivariable linear regression analysis was conducted to determine the predictors of a successful pregnancy.ResultsThirty-five 35 patients wished to become pregnant: 12 got pregnant spontaneously, while 21 failed to become pregnant (spontaneously). The mean age of the patients at the survey was 34 ± 7. Regular menstrual cycles after renal transplantation, tacrolimus-mycophenolate mofetil maintenance protocol, and age at transplantation were found to be predictors of spontaneous pregnancy. The duration of peritoneal dialysis was significantly longer in the infertile group (48 vs 12 months).ConclusionEnd-stage renal disease's negative impacts, including menstrual abnormality and fertility problems, can be overcome by successful kidney transplantation with appropriate immunosuppression. Minimizing the duration of peritoneal dialysis, particularly in patients who desire future fertility, may be accepted as a logical management strategy.
