阿托伐他汀对高胆固醇血症患者的血脂和血管内皮功能的影响

目的研究阿托伐他汀对高胆固醇血症血脂和血管内皮功能的影响.方法将高脂血症患者128例随机分为阿托伐他汀组(n＝64)和辛伐他汀组(n＝64),服药前及服药后4、8周测定血脂,并应用高频超声测定反应性充血时和含服硝酸甘油后肱动脉内径.结果服药4周后两组总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)及甘油三酯(TG)均明显降低(P<0.01),两组作用相似.治疗后两组反应性充血时和含服硝酸甘油后肱动脉内径均高于治疗前,两组比较无明显差异.含服硝酸甘油后肱动脉内径的扩张程度阿托伐他汀组强于辛伐他汀组.结论阿托伐他汀能显著降低高胆固醇血症患者血清TC、LDL-C及TG和改善血管内皮功能,并且其作用与辛伐他汀相似.     

Treatment algorithms for high responders: What we can learn from randomized controlled trials,real-world data and models

A high ovarian response to conventional ovarian stimulation (OS) is characterized by an increased number of follicles and/or oocytes compared with a normal response (10–15 oocytes retrieved). According to current definitions, a high response can be diagnosed before oocyte pick-up when >18–20 follicles ≥11–12 mm are observed on the day of ovulation triggering; high response can be diagnosed after oocyte pick-up when >18–20 oocytes have been retrieved. Women with a high response are also at high risk of early ovarian hyper-stimulation syndrome (OHSS)/or late OHSS after fresh embryo transfers. Women at risk of high response can be diagnosed before stimulation based on several indices, including ovarian reserve markers (anti-Müllerian hormone [AMH] and antral follicle count [AFC], with cutoff values indicative of a high response in patients with PCOS of >3.4 ng/mL for AMH and >24 for AFC). Owing to the high proportion of high responders who are at the risk of developing OHSS (up to 30%), this educational article provides a framework for the identification and management of patients who fall into this category. The risk of high response can be greatly reduced through appropriate management, such as individualized choice of the gonadotropin starting dose, dose adjustment based on hormonal and ultrasound monitoring during OS, the choice of down-regulation protocol and ovulation trigger, and the choice between fresh or elective frozen embryo transfer. Appropriate management strategies still need to be defined for women who are predicted to have a high response and those who have an unexpected high response after starting treatment.     

基于平扫CT的Logistic回归模型和朴素贝叶斯模型预测血肿扩大

目的 探究基于平扫CT的Logistic回归模型和朴素贝叶斯(NB)模型预测自发性脑出血早期血肿扩大(HE)的价值.方法 回顾性分析208例自发性脑出血患者的临床、初次CT扫描和24 h内随访CT资料,以随访CT显示血肿体积比例较前增加＞33％或体积差＞6 ml为HE,将患者分为HE组(86例)和非HE组(122例)....     

Interferon-lambda: New role in intestinal symptoms of COVID-19

The tremendous public health and economic impact of coronavirus disease 2019(COVID-19), caused by severe acute respiratory syndrome coronavirus 2(SARSCoV-2), has become a huge challenge globally. There is increasing evidence that SARS-CoV-2 induces intestinal infections. Type Ⅲ interferon(IFN-λ) has an antiviral role in intestinal infection, with focused, long-lasting, and non-inflammatory characteristics. This review presents a summary of the structure of SARSCoV-2, including its invasion and i...
