Antenatal corticosteroid therapy: Current strategies and identifying mediators and markers for response

Landmark early work has led to the nearly universal use of antenatal corticosteroids to accelerate fetal lung maturity with pregnancies complicated by impending preterm birth. Antenatal corticosteroids clearly reduce respiratory morbidity, death, and other adverse neonatal outcomes. Limited pregnant human pharmacokinetic data and some animal data give clinicians some information as to the behavior of the drug in the body. However, there is controversy about the type, amount, and frequency of steroid to use for this therapy. This review article summarizes the history, clinical use, and pharmacology of antenatal steroids. In addition, the review highlights some potential mediators of steroid response and current research strategies aimed at possible optimization of this therapy.     

The apoptotic and autophagic properties of two natural occurring prodrugs,hyperoside and hypoxoside,against pancreatic cancer cell lines

Pancreatic cancer is only the 12th most common cancer, but the fourth leading cause of cancer-related deaths in the world. This is due to late prognosis, poor response to chemotherapy and early metastases. Natural prodrugs may play an important role in the treatment of pancreatic cancer. The main aim of this study was to determine the cytotoxicity of five natural prodrugs, namely harpagoside, hyperoside, hypoxoside, oleuropein and polydatin, by investigating apoptosis and autophagy as possible mechanism/s of action. Hypoxoside and hyperoside have shown selective cytotoxicity at IC50 values of ∼25 and 50 μM against INS-1 and MIA PaCa-2 pancreatic cancer cells, respectively. Hypoxoside and hyperoside induced G2/M phase arrest and caspase-3 activation in INS-1 and MIA PaCa-2 cells, respectively. Hoechst/phalloidin staining confirmed morphological changes, including condensed chromatin multinucleation, membrane blebbing and loss of cytoskeletal arrangement in INS-1 and MIA PaCa-2 cells. Acridine orange staining was absent in INS-1 (hypoxoside) and MIA PaCa-2 (hyperoside) treated cells, whereas LC3B expression was not significantly increased. INS-1 and MIA PaCa-2 treated cells favour the cell death pathway, apoptosis, over the cell survival pathway, autophagy.

Low expression of let-7 predicts poor prognosis in patients with multiple cancers: a meta-analysis

The connection between microRNA expression and cancers has been identified, and microRNAs may be considered as important prognostic biomarkers. However, it is still inconsistent whether expression of let-7 can predict prognosis in patients with multiple cancers. A meta-analysis was performed by searching PubMed, EMBASE, and ISI Web of Science databases. All data were extracted from articles comparing prognosis in patients with multiple cancers having low expression of let-7 with those having high expression. Pooled hazard ratios (HRs) and corresponding 95 % confidence intervals (CIs) were calculated. Subgroup analyses were conducted for cancer type and ethnicity. A total of 1,757 cases of multiple cancers were involved for this meta-analysis. The HR of low let-7 expression in multiple cancers was 1.80 (95 % CI 1.18–2.76), and that in lung cancer was 1.99 (95 % CI 1.17–3.40). A subgroup analysis was performed on ethnicity; combined HR was 1.61 (95 % CI 0.84–3.11) for Asians and 1.94 (95 % CI 1.11–3.39) for non-Asians. Low expression of let-7 might predict poor prognosis in patients with multiple cancers, especially in lung cancer. Furthermore, let-7 might be a biomarker in non-Asian patients with favorable prognosis.     

脂联素、同型半胱氨酸在退行性心瓣膜病患者中的水平变化及其临床意义

目的:探讨老年退行性心瓣膜病患者脂联素及同型半胱氨酸的水平变化及其意义。方法:选择老年退行性心瓣膜病患者80例作为观察组,健康者60例作为对照组。比较组间脂联素、同型半胱氨酸水平差异,分析其与瓣膜病变程度、瓣膜病变数量之间的关系。结果:观察组血清脂联素水平明显低于对照组(P<0.01)、同型半胱氨酸水平明显高于对照组(P<0.01);随着瓣膜病变数量增多及返流程度加重,脂联素水平进行性下降(P<0.05),同型半胱氨酸水平进行性升高(P<0.05)。结论:低脂联素血症及高同型半胱氨酸血症可能是老年退行性心瓣膜病的危险因素。     

卒中单元护理对脑卒中患者下呼吸道感染的影响

目的探讨卒中单元管理模式对脑卒中患者下呼吸道感染及脑卒中预后的影响。方法将2009年1月～2009年11月入住卒中单元的脑卒中患者作为干预组,将2008年入住普通病房的脑卒中患者作为对照组,比较两组脑卒中患者下呼吸道感染发生率、平均住院日、抗感染治疗相关费用。结果对照组脑卒中患者下呼吸道感染率为13.30%,干预组下呼吸道感染率为7.76%。干预组平均住院日明显少于对照组（P=0.048）,干预组平均感染天数明显少于对照组（P=0.016）,干预组平均感染相关费用明显少于对照组（P=0.030）。结论通过卒中单元管理模式,可有效地降低下呼吸道感染率,减少平均住院日,降低住院费用。     

通心络胶囊对不稳定型心绞痛病人血栓前状态的影响

目的观察不稳定型心绞痛病人血浆纤溶酶原激活物抑制物-1(PAI-1)、血栓素B2(TXB2)、6-酮-前列环素F1α(6-Keto-PGF1α)含量变化及通心络胶囊对其影响.方法将48例不稳定型心绞痛病人随机分为对照组(基础治疗)和治疗组(基础治疗加通心络胶囊治疗).分别用酶联吸附双抗体夹心法、放射免疫法检测治疗前后血浆PAI-1、TXB2、6-Keto-PGF1α含量,并观察不稳定型心绞痛病人治疗前后临床症状及心电图变化来评价通心络胶囊对不稳定型心绞痛的临床疗效.结果治疗4周后,两组病人临床症状、心电图变化得到改善,治疗组和对照组治疗总有效率分别为90.00%、86.67%,无统计学意义(P＞0.05).两组病人治疗后血浆PAI-1、TXB2含量较治疗前明显下降(P＜0.01),且治疗组比对照组下降更显著(P＜0.05).结论通心络胶囊能有效地改善不稳定型心绞痛病人血栓前状态,提高其临床疗效.     

伴有肛周疾病的炎症性肠病患者肛门功能及生活质量分析

目的分析肛周疾病对炎症性肠病（IBD）患者肛门直肠功能和生活质量的影响。 方法回顾性分析2018年6月至2020年6月淮安市第二人民医院收治的伴有肛门不适的53例IBD患者（IBD组）。其中CD43例，UC10例。包括肛瘘35例，大便失禁15例，肛门纤维化8例。选择同期来淮安市第二人民医院体检的健康人20名作为健康对照组。通过肛门直肠测压对IBD患者和健康对照组受试者肛门功能进行评估并进行比较。采用炎症性肠病患者生活质量量表（IBDQ）评分对IBD患者生活质量进行评估。 结果IBD患者与健康对照组最大肛门静息压、最大挤压压、直肠容量感觉阈值、最大耐受容量、肛管抑制反射阳性水平差异均无统计学意义（P均>0.05）。大便失禁的IBD患者最大肛门静息压、IBDQ评分均低于非大便失禁的IBD患者，且差异均有统计学意义（P<0.05）。CD与UC患者IBDQ评分差异无统计学意义（P>0.05）；大便失禁IBD患者IBDQ评分低于非大便失禁IBD患者，且差异有统计学意义（P<0.05）。 结论合并肛周疾病的IBD患者肛门直肠功能受损，大便失禁的患者生活质量差。
