Effect of Yinqi Ointment on Wound Morphology and Growth Factor in Treating Diabetic Foot Ulcer

Objective: To investigate the effect of Yinqi ointment on wound morphology and growth factor in treating diabetic foot ulcer(DFU).Methods: From December 2016 to December 2017, 92 cases of DFU with deficiency of both Qi and Yin syndrome were randomly divided into treatment group and control group(44 cases in each group). The treatment group was treated with Yinqi ointment, while the control group was treated with mupirocin ointment. After 4 weeks of treatment, the ulcer healing effect, ulcer area, granulation tissue, epithelial tissue coverage,pain score, and dynamic analysis of vascular endothelial growth factor(VEGF), epidermis growth factor(EGF), and basic fibroblast growth factor(bFGF) in local granulation tissue were statistically analyzed before and after treatment in both groups. Results: The total effective rate was 88.37% in the treatment group and 74.42% in the control group. The wound reduction rate, epithelial tissue coverage rate, granulation tissue growth rate, and local pain relief rate in the treatment group were significantly superior to those in the control group(P 0.05). Through the local granulation detection, the treatment group and the control group have increased VEGF, EGF, and bFGF, but the treatment group increased the role of growth factor than the control group. Conclusion: Yinqi ointment can promote the healing of DFU, and its mechanism may be related to the increase of the content of growth factor in granulation tissue.     

中药调节黏膜免疫系统用于防治COVID-19的思路探索

机体免疫功能低下患者,极易出现新型冠状病毒感染,与中医所说正气不足、邪毒侵扰一致。目前集中在抗病毒药物研发是必须的,但对于调节机体免疫系统制剂的研究也较为迫切。黏膜组织是人体免疫系统的一道重要屏障,具有独特功能和结构的独立免疫体系,是机体抵抗感染的第一道防线,与外界抗原(比如食物、共生菌、病毒等)直接接触。其在抵抗病毒、抗感染方面,黏膜免疫(如呼吸道黏膜、肠道黏膜等)起着极其重要的作用,可以消灭外来病原微生物或其他外来抗原,不至于病毒侵入机体组织而对机体造成损伤。中药通过黏膜免疫系统发挥治疗作用的研究报道日益增多,该文拟针对黏膜免疫系统与新型冠状病毒肺炎(COVID-19)的关系以及中药的干预机制展开探讨,以期为COVID-19的防治提供可借鉴的研究方法与治疗思路。     

降逆胃舒汤治疗萎缩性胃炎疗效及对患者病理评分的影响

目的:研究降逆胃舒汤对幽门螺杆菌感染致萎缩性胃炎病理评分的功效。方法:选取238例幽门螺杆菌感染致萎缩性胃炎患者作为本次研究观察对象,入选患者遵循随机数字表法平均分配入对照组与治疗组,对照组以常规西药四联疗法治疗,治疗组在对照组疗法的基础上给予降逆胃舒汤治疗; 治疗3个月后,观察两组患者HP清除率并随访6个月统计复发率,观察两组患者中医证候积分、胃黏膜胃镜征象积分、胃黏膜病理评分及血清胃泌素-17(G-17)、血清胃蛋白酶原Ⅰ、Ⅱ(PGⅠ、PGⅡ)、PGⅠ/PGⅡ比值(PGR)治疗前、后的变化情况。结果:治疗前两组患者各项中医证候、胃黏膜胃镜积分、病理评分及血清指标表达水平比较,差异无统计学意义(P>0.05); 治疗后两组患者各项中医证候、胃黏膜胃镜积分、病理评分及血清指标表达水平比较,差异有统计学意义(P<0.05),治疗组均优于对照组(P<0.05); 治疗后3个月时治疗组HP清除率为88.24%、对照组为73.11%,随访6个月治疗组复发率为3.81%,对照组为18.39%,两组HP根除率、复发率比较,差异有统计学意义(P<0.05)。结论:降逆胃舒汤能够提高幽门螺杆菌清除率并降低复发,更有效缓解幽门螺杆菌感染致萎缩性胃炎的各项中医证候,进一步改善患者胃黏膜病理评分与胃镜征象,更良好的调节患者血清指标。     

补肾填髓汤对股骨骨折术后延迟愈合的效果观察

目的:观察和分析补肾填髓汤对股骨骨折术后延迟愈合的效果。方法:回顾分析了2014年4月-2017年4月期间在我院进行了股骨骨折术后延迟愈合治疗的40例患者的治疗过程,分为对照组(20例)和观察组(20例)。对照组患者予常规治疗,观察组则在对照组治疗的基础之上加入补肾填髓汤进行治疗。治疗后,对比两组患者之间的疗效以及骨代谢指标。结果:治疗前,两组患者骨代谢指标之间差异无统计学意义(P>0.05)。治疗后,观察组患者代谢指标改善情况优于对照组,P<0.05,两组之间差异存在统计学意义。治疗后,观察组疗效高于对照组,P<0.05,差异存在统计学意义。结论:使用补肾填髓汤治疗股骨骨折术后延迟愈患者能够大幅度提高患者疗效,提升治疗过程中的安全性,值得推广。     

Luminal 5‐HT4 receptors—A successful target for prokinetic actions

The prokinetic effects of 5‐HT₄ receptor (5‐HT₄R) agonists have been utilized clinically for almost three decades to relieve symptoms of constipation. Surprisingly, the mechanism(s) of action of these compounds is still being debated. Recent studies highlight luminal 5‐HT₄Rs as an alternative and effective target for these prokinetic agents. These include the study by Shokrollahi et al (2019, Neurogastroenterol Motil, e13598) published in the current issue of Neurogastroenterology and Motility, who found that activation of mucosal 5‐HT₄Rs by intraluminal prucalopride, significantly enhanced propulsive motor patterns in rabbit colon. The authors highlight the idea that development of agonists targeting luminal 5‐HT₄Rs in the colonic mucosa might be more effective and safer in achieving prokinetic effects on intestinal motility. The purpose of this mini‐review is to discuss the evidence for luminal 5‐HT₄Rs as an emerging target for prokinetic agents in facilitating propulsive motor patterns in the colon.
