肠炎清合剂治疗慢性复发型溃疡性结肠炎大肠湿热证的临床观察

目的:观察肠炎清合剂对慢性复发型溃疡性结肠炎(UC)大肠湿热证患者诱导缓解效果及维持治疗对复发的影响,并从神经-内分泌-免疫炎症网络方面探讨了其作用机制。方法:将112例符合要求的患者随机分成对照组55例和观察组57例。对照组内服美沙拉嗪肠溶片,1.0 g/次,4次/d;Mayo评分系统≥7分者,加服醋酸泼尼松片,0.75 mg·kg^-1·d^-1;加用双歧杆菌活菌散剂,1包/次,2次/d,餐后温水冲服。观察组在对照组治疗的基础上服用肠炎清合剂,1包/次,分早晚2次服用。两组疗程均为连续治疗6周,再每周门诊复诊1次。进入缓解期后,两组患者均给予美沙拉嗪肠溶片,0.5 g/次,3次/d,维持治疗;观察组仍内服肠炎清合剂内服,至大肠湿热证评分减少≥90%以上。记录进入6周内缓解期的人数和缓解时间;进行治疗前后结肠镜检查,并进行Geboes指数和Baron法评价;进行治疗前后大肠湿热证评分和Mayo评分;检测治疗前后外周血白细胞介素-6(IL-6),IL-8,IL^-10,IL^-17,血管活性肠肽(VIP),胃动素(MTL)和神经肽Y(NPY);随访24周,记录复发情况。结果:经6周治疗后,观察组临床有效率为100%,黏膜愈合率为96.4%,均分别高于对照组的89.09%和81.82%(P<0.05),两组患者内镜应答率均为100%;经6周治疗后,观察组临床缓解率为91.23%,高于对照组的76.36%(χ2=4.581,P<0.05),观察组平均缓解时间短于对照组(P<0.01);治疗后观察组结肠黏膜评分,Geboes指数、大肠湿热证评分和Mayo评分均低于对照组(P<0.01);观察组患者外周血IL-6,IL-8和IL^-17水平均低于对照组(P<0.01),IL^-10水平高于对照组(P<0.01);观察组患者外周血VIP,MTL水平均低对照组(P<0.01),NPY水平高于对照组(P<0.01);观察组复发率为17.54%,低于对照组的38.18%(χ2=5.955,P<0.05);观察组平均复发时间长于对照组(P<0.01)。结论:在常规西医治疗的基础上,肠炎清合剂用于慢性复发型UC大肠湿热证的治疗,可诱导病情缓解,缩短病程,并能降低复发率,推迟复发时间,并对神经-内分泌-免疫炎症网络具有调节作用,从而可改善病情。     

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.

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.     

Tanzania IR Initiative: Training the First Generation of Interventional Radiologists

Despite a population of nearly 60 million, there is currently not a single interventional radiologist in Tanzania. Based on an Interventional Radiology (IR) Readiness Assessment, the key obstacles to establishing IR in Tanzania are the lack of training opportunities and limited availability of disposable equipment. An IR training program was designed and initiated, which relies on US-based volunteer teams of IR physicians, nurses, and technologists to locally train radiology residents, nurses, and technologists. Preliminary results support this strategy for addressing the lack of training opportunities and provide a model for introducing IR to other resource-limited settings.
