基于网络药理学的气滞胃痛颗粒抗炎镇痛活性作用分析

目的通过网络药理学的方法预测气滞胃痛颗粒抗炎镇痛主要活性成分的作用靶点,结合中医方解配伍理论对其多成分-多靶点-多通路的作用进行分析。方法基于TCMSP中药系统生物学分析数据库收集气滞胃痛颗粒中6味中药的主要化学成分,并借助LC-MS技术对所筛成分进行分析,通过TCMSP检索和Pharmmapper软件预测获取各成分主要的作用靶标,并通过DIP数据库,利用蛋白质相互作用信息建立药物靶标与炎症疼痛靶标的关联,构建药物-靶标-疾病网络,通过网络特征分析气滞胃痛颗粒抗炎镇痛的作用靶标,阐释其抗炎镇痛的主要作用机制。结果根据网络分析,共有44个炎症疼痛靶点与气滞胃痛颗粒密切相关,其中直接作用靶点有20个,主要是对环加氧酶-2(COX-2)和诱导型一氧化氮合酶(i NOS)等蛋白酶的作用,作用机制可能与调节肿瘤坏死因子(TNF)信号通路、NOD样受体(NLR)信号通路、血管内皮生长因子(VEGF)信号通路等与炎症疼痛密切相关的信号通路有关。结论气滞胃痛颗粒抗炎镇痛作用体现了中药多成分、多靶点、多途径的作用特点,该研究为深入阐释气滞胃痛颗粒抗炎镇痛作用机制提供科学依据,并且进一步说明了中医药古方配伍理论的科学性。     

Profilin 1, negatively regulated by microRNA-19a-3p,serves as a tumor suppressor in human hepatocellular carcinoma

Profilin 1 (PFN1) is a critical actin-regulatory protein; however, its functional role in hepatocellular carcinoma (HCC) progression remains to be further elucidated. In the present study, we observed that the expression levels of PFN1 were significantly decreased in HCC tissues and cell lines. Low PFN1 expression was significantly correlated with aggressive clinicopathological characteristics and poor prognosis of HCC patients. Further in vitro experiments demonstrated that overexpression of PFN1 remarkably inhibited the proliferation, migration, invasion and EMT of HCC cells. Moreover, we also found that PFN1 was a direct target gene of miR-19a-3p, and in HCC tissues, and there was a significantly inverse correlation between PFN1 mRNA and miR-19a-3p expression. Collectively, our results showed that PFN1 functions as a tumor suppressor in HCC, and might serve as a diagnostic and therapeutic target for HCC patients.     

中医药治疗慢性前列腺炎研究概况

综述近年中医药治疗慢性前列腺炎的临床研究,认为本病病因病机之核心在于脾肾亏虚为本,湿热、痰浊、瘀毒为标,病久则伤及脾肾,由实转虚。中医内治法主要以辨证论治、辨病论治或单方验方为主,外治法以中药洗浴、中药灌肠、肛门给药、针灸为主。中医药治疗本病优势明显。应继续完善对中医药作用机制的认识,制订统一的辨证论治及疗效评价标准,针对效果显著的名方开展研究。     

南宁市江南区2019年登革热流行病学特征和疫情应急处置分析

目的 分析总结南宁市江南区2019年登革热流行病学特征和疫情应急处置的工作情况,为今后有效地防制登革热提供对策、参考和技术支持。方法 收集南宁市江南区2019年登革热疫情相关数据,评价本次应急处置的工作成效。结果 2019年南宁市江南区登革热疫情严峻,共报告登革热病例370例,其中输入病例4例,本地病例366例;感染人数以家务待业和离退休者居多;男女性别比为1∶1.12;发病年龄最小1岁,最大92岁;发病的空间分布呈现高度聚集,福建园街道占本城区本地病例的87.70%。早期伊蚊应急监测布雷图指数和账诱指数合格率偏低,分别为72.17%和62.61%。针对本次疫情特性,制定有针对性的防控策略,做好精准疫情应急处置,有效压低峰值,迅速控制了疫情的扩散和蔓延。结论 本次疫情是由输入性病例导致本地病例社区水平暴发,疫情呈现多点暴发及扩散蔓延态势。需做好疫情研判、预警预测,准确分析流行病学特征,尽早实施登革热应急处置,精准防控、孳生地处理、健康宣教和病例管理是应急处置的关键措施。     

腹腔镜胆囊切除术患者围术期多项血清应激状态相关指标变化观察

目的:分析腹腔镜胆囊切除术的临床疗效,分析其对血清应激指标的影响。方法:将160例来我院行胆囊切除术的患者随机分为两组,对照组和观察组各80例。对照组采用开腹胆囊切除术,观察组则采用腹腔镜胆囊切除术。比较两组间手术时间、术中出血量、肠功能恢复时间以及住院天数差异,比较治疗前后两组患者间血清应激相关指标皮质醇(COR)、去甲肾上腺素(NE)、促肾上腺皮质激素(ACTH)、多巴胺(DA)以及胰岛素(INS)、三碘甲状腺原氨酸(T3)、甲状腺素(T4)、促甲状腺激素释放激素(TSH)水平差异。结果:观察组患者手术时间、术中出血量、肠功能恢复时间以及住院天数均显著少于对照组(P<0.05)。血清COR、NE、ACTH、DA和INS、T3水平在围手术期均发生了显著变化,各项指标均在胆囊分离时就明显升高,术后24 h开始下降(P<0.05);术后观察组上述指标均显著低于对照组(P<0.05)。结论:腹腔镜胆囊切除术对机体应激反应影响小于开腹手术,更利于患者术后康复。     

Elevated serum levels of Interleukin‐37 are associated with inflammatory cytokines and disease activity in rheumatoid arthritis

Interleukin‐37 (IL‐37) is closely associated with several inflammatory diseases. However, the role of IL‐37 in the pathogenesis of rheumatoid arthritis (RA) remains unclear. The aim of this study was to assess the associations between serum levels of IL‐37 and disease activity, inflammatory cytokines, and bone loss in patients with RA. Serum cytokines levels were examined by Enzyme‐linked immunosorbent assay (ELISA). Radiographic bone erosion was assessed using the van der Heijde‐modified Sharp score and bone mineral density (BMD) was measured using DXA. Serum IL‐37 levels in RA patients were significantly higher than those in HCs (p < 0.001), and were significantly positively correlated with clinical parameters of disease activity and serum levels of IL‐17 and IL‐23. In addition, serum IL‐37 levels were significantly higher in patients with stage IV of radiographic bone erosion than those with stage III and stage I–II, and they were significantly higher in those with osteopenia and osteoporosis than in those with normal BMD. Our results suggest that serum IL‐37 levels were increased in patients with RA and were positively associated with disease activity, IL‐17/IL‐23 and bone loss in RA, suggesting that IL‐37 may play a critical role in the pathogenesis of RA.
