Efficacy and Safety of the Modified EPOCH Regimen (Etoposide,Vincristine, Doxorubicin,Carboplatin, and Prednisolone) for Adult T-cell Leukemia/Lymphoma: A Multicenter Retrospective Study

BackgroundWe retrospectively analyzed patients with untreated aggressive adult T-cell leukemia/lymphoma who received the modified EPOCH (mEPOCH) regimen.Patients and MethodsPatients received up to 6 mEPOCH cycles. Etoposide (50 mg/m²/day), doxorubicin (10 mg/m²/day), and vincristine (0.4 mg/m²/day) were each given as a continuous 96-hour infusion on days 1 to 4. Prednisolone (40 mg/m²/day) was given intravenously or orally on days 1 to 4 and then tapered and stopped on day 7, and carboplatin (dose calculated for each patient individually using Calvert’s formula according to a target under the curve of 3 mg/mL/min) was given as a 2-hour intravenous infusion on day 6.ResultsIn 103 patients, overall response rate and complete response rate were 58% and 25%, respectively. With a median follow-up of 8.9 months, the median survival time was 9.8 months (95% confidence interval, 7.2-13.9 months). The median progression-free survival (PFS) was 4.2 months (95% confidence interval, 3.4-5.7 months). Patients who completed ≥ 4 cycles experienced significantly better overall survival and PFS compared with those who completed < 4 cycles. Twenty-eight patients underwent allogeneic hematopoietic stem cell transplantation after mEPOCH and demonstrated significantly prolonged overall survival and PFS compared with those who did not undergo transplantation.ConclusionThe mEPOCH regimen is effective with tolerable adverse effects and may be an alternative treatment option for adult T-cell leukemia/lymphoma.     

补肾壮骨汤对骨质疏松型胸腰椎压缩骨折患者椎体成形术治疗效果影响的Meta分析

[目的]采用Meta分析法系统评价补肾壮骨汤对椎体成形术治疗骨质疏松型胸腰椎压缩骨折(OTCF)临床的影响。[方法]以"补肾壮骨汤"为首输关键词,以"椎体成形术""骨质疏松""胸腰椎压缩骨折"等为次输关键词,全面搜索补肾壮骨汤对OTCF患者椎体成形术治疗效果影响的随机对照研究文献,评价纳入研究文献的一般特征,对文献资料所提取的治疗有效率、骨密度、Oswestry功能障碍(ODI)指数、治疗安全性(新发骨折率)等观察指标进行Meta分析处理与分析。[结果]共13篇文献纳入Meta分析范畴,文献总样本量1 037例。分析显示,与对照组相比,治疗组可明显提高临床有效率[OR=4.63,95%CI[2.92,7.36],P0.000 01]、改善骨密度[MD=0.08,95%CI[0.06,0.1],P0.000 01]、降低ODI指数[MD=-2.34,95%CI[-3.49,-1.19],P0.000 01]、降低新发骨折率[OR=0.08,95%CI[0.11,0.44],P0.000 01]。[结论]与单纯椎体成形术治疗相比,补肾壮骨汤辅助椎体成形术在OTCF患者治疗中,可提升患者术后骨密度、改善胸腰椎功能障碍和降低术后新发骨折率,治疗疗效确切。     

黄芪活血功效及现代药理学研究进展

黄芪始载于《神农本草经》,有补气升阳、益卫固表,利水消肿,托毒生肌之效。被誉为补气健脾之要药,临床上常用于气虚乏力、脾虚泄泻等疾病,已为医者所熟知。近年来,研究学者围绕其补气、健脾、利水功效机制已有较全面的认识。然陶弘景在《本草经集注》首载黄芪"逐五脏间恶血",表明本品兼有活血作用。目前,对于本品活血作用机制阐释,中医常基于"补气活血""气行血行"理论进行论证,但并不等同于本品无活血作用。通过梳理历代本草文献中对黄芪的记载,发现其活血作用应用广泛。综合传统方剂与现代方剂中有关其活血作用的应用,本品在方中行活血通络、活血利水、活血扶正作用,尤能体现其活血作用。且现代药理学研究在有关瘀血病理指标的分子机制中,黄芪有很好的调控作用,表明黄芪有活血作用,但未深入探究,存在研究价值。该文从历代文献对黄芪活血功效的论述、黄芪活血作用的临床应用及现代药理学研究深入探讨其活血作用机制,以期扩展黄芪的临床应用范围,为临床治疗提供理论指导。     

The effect of nettle (Urtica dioica) supplementation on the glycemic control of patients with type 2 diabetes mellitus: A systematic review and meta‐analysis

Type 2 diabetes mellitus (T2DM) is a major health problem, worldwide, that is associated with increased morbidity and mortality. Several randomized controlled clinical trials (RCTs) have investigated the effect of nettle (Urtica dioica) supplementation on markers of glycemic status in patients with T2DM, with conflicting results. Therefore, the present study assessed the effect of nettle on some glycemic parameters in patients with T2DM. A comprehensive search was conducted in PubMed, Scopus, Cochrane Library, and Web of Science, from database inception up to June 2019, to identify RCTs investigating the effect of nettle supplementation on glycemic markers, including fasting blood sugar (FBS) concentrations, insulin levels, homeostasis model assessment‐estimated insulin resistance index, and glycosylated hemoglobin percentage in adults with T2DM. The Cochrane Collaboration tool was used to assess the methodological quality of the included studies. Results of this meta‐analysis were reported based on the random effects model. Eight RCTs, comprising 401 participants, were included in the present systematic review and meta‐analysis. Based on the Cochrane Collaboration risk of bias tool, five studies were considered as good quality, one was fair, and two studies were poor, respectively. The results of the meta‐analysis revealed a significant reduction in FBS concentrations (weighted mean difference [WMD]: ?18.01 mg/dl, 95% confidence interval [CI]: ?30.04 to ?5.97, p < .001, I² = 94.6%) following nettle supplementation. However, no significant reduction was observed in insulin levels (WMD: 0.83 Hedges' g, 95% CI: ?0.26 to 1.92, p = .13, I² = 89.4%), homeostasis model assessment‐estimated insulin resistance index (WMD: ?0.22, 95% CI: ?0.83 to 0.40, p = .49, I² = 69.2%), or glycosylated hemoglobin percentage (WMD: ?0.77%, 95% CI: ?1.77 to 0.22, p = .12, I² = 83.0%). The findings of the present study suggest that nettle supplementation may be effective in controlling FBS for T2DM patients. However, further studies are needed to confirm the veracity of these results.
