从气从痰论治顽固性胃食管反流病

胃食管反流病多因饮食不节、七情失和、素体禀赋虚弱等原因,导致脾胃受损,土壅木郁,肝胃不和,胃失和降,胃气上逆,出现反酸、烧心、嗳气、胃胀等症状。其发生与肝、脾、胃密切相关,气机逆乱,胃失和降是其基本病机。由于本病病程较长,病情易反复发作,易成为顽固性胃食管反流病。而顽固性胃食管反流病多为本虚标实之证,本虚是指因疾病反复发作所导致的脾胃虚弱,标实是指由于脾胃虚弱、脾失健运、土壅木郁、气机不畅所导致的痰湿、气滞、热郁、血瘀等实邪。最后结局是痰气郁(瘀)交阻,脾胃升降失司,胃气上逆,从而引起反酸烧心反复发作,缠绵难愈。纵观核心病机,乃"气郁"、"痰阻"导致的胃失和降、胃气上逆。治疗顽固性胃食管反流病时宜"从气而治""从痰而治"。     

“从肠论治”脓毒症截断扭转防治策略的理论与实践

脓毒症是机体应对感染失控反应所致威胁生命的器官功能障碍,其病死率居高不下,全球大约每年大约有530万患者死亡,故深入探究脓毒症的发病机制和寻找有效的治疗药物是目前医学界的重要课题。中医药治疗脓毒症具有潜在优势,本团队在继承朱良春国医大师、国家非物质文化遗产“顾氏外科”奠基人顾伯华教授学术经验基础上,通过临床实践,首次提出"从肠论治”截断扭转防治脓毒症策略,为中医药治疗脓毒症提供了新的思路。     

MicroRNA‐375‐3p enhances chemosensitivity to 5‐fluorouracil by targeting thymidylate synthase in colorectal cancer

Resistance to chemotherapy is a major challenge for the treatment of patients with colorectal cancer (CRC). Previous studies have found that microRNAs (miRNAs) play key roles in drug resistance; however, the role of miRNA‐373‐3p (miR‐375‐3p) in CRC remains unclear. The current study aimed to explore the potential function of miR‐375‐3p in 5‐fluorouracil (5‐FU) resistance. MicroRNA‐375‐3p was found to be widely downregulated in human CRC cell lines and tissues and to promote the sensitivity of CRC cells to 5‐FU by inducing colon cancer cell apoptosis and cycle arrest and by inhibiting cell growth, migration, and invasion in vitro. Thymidylate synthase (TYMS) was found to be a direct target of miR‐375‐3p, and TYMS knockdown exerted similar effects as miR‐375‐3p overexpression on the CRC cellular response to 5‐FU. Lipid‐coated calcium carbonate nanoparticles (NPs) were designed to cotransport 5‐FU and miR‐375‐3p into cells efficiently and rapidly and to release the drugs in a weakly acidic tumor microenvironment. The therapeutic effect of combined miR‐375 + 5‐FU/NPs was significantly higher than that of the individual treatments in mouse s.c. xenografts derived from HCT116 cells. Our results suggest that restoring miR‐375‐3p levels could be a future novel therapeutic strategy to enhance chemosensitivity to 5‐FU.

南充市自发性脑出血发病与气温的相关性及滞后效应

目的分析南充市自发性脑出血（sICH）发病与气温的相关性及滞后关系。 方法收集南充市全市范围内二级以上医院2014年1月至2018年12月收治的sICH患者病例资料及同期气温数据，利用Spearman等级相关法确定最佳温度指标，将其组建分布滞后非线性模型，评估其与sICH日发病风险的暴露-剂量反应关系，分层分析各温度节点在性别及年龄组别的滞后-剂量反应关系。 结果共收集sICH患者资料13 952例。Spearman相关性分析揭示sICH日发病人数与日均气温呈非线性负相关（r=-0.324，P<0.05）。分布滞后非线性模型分析结果表明极低温和低温当天sICH的相对危险度为1.68（1.35~2.08）及1.47（1.24~1.72），危害效应最大，其随着滞后天数增加而减弱，极低温滞后1~2 d，低温持续滞后1~10 d。低龄组（18~60岁）在极低温、低温下滞后2 d，高龄组（>60岁）在极低温下滞后10 d，低温下滞后24 d。不同性别组在极低温、低温下滞后效应趋势一致，随滞后天数增加风险下降。 结论低温增加sICH发病风险，早期呈明显急性影响，且具有滞后效应，老年人对低温反应更加滞后。     

User experiences with second-generation 32-gauge × 4 mm vs. thinner comparator pen needles: prospective randomized trial
