不同针灸疗法治疗寻常痤疮的网状Meta分析＊

目的 采用网状Meta分析方法，评价针刺、火针、艾灸等不同针灸疗法对寻常痤疮（acne vulgaris， AC）临床有效率及复发率的影响。方法 计算机检索PubMed、Embase、Cochrane、Web of Science、CINAHL、中国知网（China National Knowledge Infrastructure， CNKI）、万方数据库（WanFang Data）、中国生物医学文献数据库（China Biology Medicine disc， CBM）和维普中文期刊服务平台（VIP Database），搜集针灸疗法治疗寻常痤疮的随机对照试验（randomized controlled trail， RCT），检索时间均为建库至2021年3月，文献筛选、资料提取及偏倚风险评价均由两名研究者独立进行。数据分析使用Stata16.0软件。结果 纳入42项RCT，共3911例寻常痤疮患者。数据分析结果显示，临床总有效率：艾灸、放血、放血+穴位注射、放血+针刺、火针优于西药（P<0.05），放血、放血+穴位注射、放血+针刺、火针、穴位埋线优于针刺疗法（P<0.05），放血+针刺疗法优于自血疗法（P<0.05），累计排序概率曲线下面积（surface under the cumulative，SUCRA）显示放血+针刺治疗寻常痤疮总有效率最高；复发率：放血疗法+穴位注射优于电针（P<0.05），SUCRA结果显示针刺+自血疗法治疗寻常痤疮复发率最低。结论 放血联合针刺疗法在提高总有效率上具有最好的疗效，针刺联合自血疗法可有效降低复发率，受纳入研究所限，以上结论尚需更多大样本、高质量RCT进一步验证。     

多维价值框架推动思政教学——药事法规课程思政建设探索

目的： 探究药事法规课程思政建设的思路与实施路径，为高等学校药学相关专业本科药事法规课程思政建设提供参考方法： 基于《高等学校课程思政建设指导纲要》的文件要求，汇总分析药事法规课程思政建设要点与思政元素，结合课堂内外资源，提出课程思政建设多维价值框架，并应用于药事法规课程思政教学中。结果与结论： 在课程思政教学中，可遵循“三结合，两巩固，一推动”的多维价值框架，将社会主义核心价值观、职业使命感、民族自豪感、中医药文化自信、家国情怀等思政元素融入其中。专业课程需起到良好的思政教学作用，但应注意坚持以学生为中心，做到“润物细无声”，有效把握不同课程思政元素的应用，并重视任课教师的言传身教，还需要对课程思政建设效果进行评价与反思，以使课程建设不断完善。     

First-line nivolumab plus chemotherapy vs chemotherapy in patients with advanced gastric,gastroesophageal junction and esophageal adenocarcinoma: CheckMate 649 Chinese subgroup analysis

First-line chemotherapy for advanced/metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric/gastroesophageal junction cancer (GC/GEJC) has poor median overall survival (OS; <1 year). We report efficacy and safety results from Chinese patients in the phase III global CheckMate 649 study of nivolumab plus chemotherapy vs chemotherapy for the first-line treatment of GC/GEJC/esophageal adenocarcinoma (EAC). Chinese patients with previously untreated advanced or metastatic GC/GEJC/EAC were randomized to receive nivolumab (360 mg Q3W or 240 mg Q2W) plus chemotherapy (XELOX [capecitabine and oxaliplatin] Q3W or FOLFOX [oxaliplatin, leucovorin and 5-fluorouracil] Q2W), nivolumab plus ipilimumab (not reported) or chemotherapy alone. OS, blinded independent central review-assessed progression-free survival (PFS), objective response rate (ORR), duration of response (DOR) and safety are reported. Of 1581 patients enrolled and randomized, 208 were Chinese. In these patients, nivolumab plus chemotherapy resulted in clinically meaningful improvement in median OS (14.3 vs 10.2 months; HR 0.61 [95% CI: 0.44-0.85]), median PFS (8.3 vs 5.6 months; HR 0.57 [95% CI: 0.40-0.80]), ORR (66% vs 45%) and median DOR (12.2 vs 5.6 months) vs chemotherapy, respectively. The safety profile was acceptable, with no new safety signals observed. Consistent with results from the global primary analysis of CheckMate 649, nivolumab plus chemotherapy demonstrated a clinically meaningful improvement in OS and PFS and higher response rate vs chemotherapy and an acceptable safety profile in Chinese patients. Nivolumab plus chemotherapy represents a new standard first-line treatment for Chinese patients with non-HER2-positive advanced GC/GEJC/EAC.     

Cyanidin-3-glucoside protects against high glucose-induced injury in human nucleus pulposus cells by regulating the Nrf2/HO-1 signaling

Cyanidin-3-glucoside (C3G) is a well-known natural anthocyanin with antioxidant and anti-inflammatory properties. In this study, we explored the role and action mechanism of C3G in high glucose (HG)-induced damage of human nucleus pulposus cells (HNPCs). Cell viability was assessed by CCK-8 assay. TUNEL assay was performed for detecting apoptotic rate. Western blot was performed to determine the expression levels of cl-caspase-3, caspase-3, Bax, Bim, collagen II, aggrecan, MMP-3, MMP-13, and ADAMTS5. Reactive oxygen species (ROS) generation was analyzed using DCFH-DA staining. The Nrf2 was knocked down or overexpressed in HNPCs through transfection with si-Nrf2 or pcDNA3.0-Nrf2. C3G treatment (12.5, 25, and 50 μM) improved cell viability of HNPCs under HG condition. HG-induced cell apoptosis of HNPCs was attenuated by C3G with decreased apoptotic rate and relative levels of cl-caspase-3/caspase-3, Bax, and Bim. C3G treatment caused significant increase in expression levels of collagen II and aggrecan and decrease in the relative levels of MMP-3, MMP-13, and ADAMTS5. After treatment with C3G, ROS generation in HNPCs was markedly reduced. Treatment with N-acetylcysteine (NAC) reversed HG-induced cell apoptosis and extracellular matrix (ECM) degradation. C3G treatment induced the expression of Nrf2 and HO-1 in HG-induced HNPCs. Moreover, knockdown of Nrf2 reversed the inhibitory effect of C3G on ROS production. Summarily, C3G exerted a protective effect on ROS-mediated cellular damage in HNPCs under HG condition, which was attributed to the induction of the Nrf2/HO-1 signaling pathway.
