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.     

Effects of the Clearing the Lung and Dissipating Phlegm Method in the Treatment of Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis

Objective: The objective of this study is to evaluate the efficacy and safety of the clearing the lung and dissipating phlegm method in the treatment of acute exacerbation of chronic obstructive pulmonary disease(COPD) and to provide evidence for the treatment of the disease. Materials and Methods: Literature was searched from the United States National Library of Medicine(PubMed), Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database(Wanfang), and the Full?Text Database of Chinese Scientific and Technical Periodicals(VIP).A comprehensive collection was made of randomized controlled trials(RCTs) before June 2018, in which the treatment groups used either the clearing the lung and dissipating phlegm formulas only or combined it with routine Western medicine therapy, and the control group adopted routine Western medicine therapy only for the acute exacerbation of COPD. The Cochrane risk of bias method was used to evaluate the quality of the literature. The data were analyzed and retrieved independently by two reviewers before meta?analysis was carried out with RevMan 5.3 software to evaluate the primary outcome measures, including the total clinical effective rate, and the secondary outcome measures such as the pulmonary function(forced vital capacity [FVC], forced expiratory volume in the 1 s [FEV1], percentage of FEV1 [FEV1%], and FEV1/FVC)and blood gases(PaO_2 and PaCo_2). Results: A total of 13 RCTs involving 990 patients(496 in the treatment group and 494 in the control group)were included in this study. Meta?analysis revealed significant difference in the efficacy of the group that adopted solely the routine Western medicine method and the group that combined the Western medicine with the clearing the lung and dissipating phlegm method. Outcome measures including the pulmonary function(FVC, FEV1, FEV1%, and FEV1/FVC) and the blood gases(PaO_2 and PaCo_2) were significantly improved as compared to the control group(P 0.00001). However, adverse effects in the treatment group using combined traditional Chinese medicine were not reported due to the short observation time of the study. Conclusion: The clearing the lung and dissipating phlegm method can improve the efficacy in the treatment of acute exacerbation of COPD, the outcome measures of the pulmonary function and the blood gases,as well as the life quality of the patients. However, due to the fact that the existing studies are generally of poor quality in which randomization and its implementation were not properly carried out, more high?quality RCTs are necessary to confirm the findings of this study.

儿童新型冠状病毒感染诊断、治疗和预防专家共识(第二版)

自2019年12月新型冠状病毒感染暴发以来,我国政府采取了严格的防控措施,国内疫情已得到初步控制,但形势依然严峻,境外多个国家也相继出现疫情。根据世界卫生组织的报告:截至2020年3月5日,全球共报告95333例确诊病例(其中我国累计报告确诊病例80565例),85个国家有确诊病例报告,中国将面临输入性病例的传播风险,这为防治我国儿童的疾病疫情提出了新的挑战[1]。在这次疫情中,与成人病例相比,儿童病例相对较少、症状轻、预后较好。目前国内病例数据显示,18岁以下儿童占所有报告病例的2.4%,尚无死亡病例报告[2]。     

良性前列腺增生与前列腺慢性炎症的相关性研究进展

良性前列腺增生（BPH）是老年男性常见的泌尿系统疾病，其发病与前列腺慢性炎症之间存在显著相关。感染因子、尿液返流、代谢综合征、衰老过程和自身免疫应答在内的几种刺激，通过相应分子途径引起前列腺免疫细胞的组织定位和组成成分发生广泛改变，从而导致免疫系统失调，之后引发的组织损伤和缓慢愈合，导致了BPH发生和进展。本文通过总结良性前列腺增生与前列腺慢性炎症的相关性的临床研究结果，前列腺免疫细胞在病理生理机制层面与前两者之间的内在联系，以及抗炎药物对BPH-LUTS的干预作用，以其为BPH-LUTS的药物研发提供参考。     

中国九市四至七岁儿童乳恒牙替换及其与体格生长的相关性分析

目的探讨中国9个城市(简称九市)4~7岁儿童乳恒牙替换及其与体格生长的关系,分析恒牙发育长期变化趋势。方法采用分层整群抽样的方法,以4~7岁儿童为调查对象,于2015年6—10月在北京、哈尔滨、西安(北片),上海、南京、武汉(中片),广州、福州、昆明(南片)九市进行横断面调查,共37973名儿童,其中男19035名,女18938名。6岁以下每6个月为1组,6~<7岁1岁为1组。现场检查乳牙脱落、恒牙萌出情况,测量身高、体重等,并依据2009年中国儿童生长标准计算体格指标Z分值。采用Probit概率单位回归方法计算换牙年龄。不同性别、地区、年龄分组组间比较采用χ2检验或t检验。并利用1995年中国九市儿童体格发育调查中乳恒牙替换相关数据,分析恒牙发育的长期变化趋势。结果九市37973名儿童随着年龄增长换牙率逐渐增加,从4.0~<4.5岁的0.6%(42/7568)增长至5.5~<6.0岁的30.3%(2295/7583),6.0~<7.0岁达到74.5%(5680/7627)。除4.0~4.5岁组外,无论城郊男童换牙率均低于女童(P均<0.05);城区换牙率(男5.5~<6.0岁、女4.5~<5.0岁组之后)略高于郊区,如6.0~<7.0岁组男童城郊分别为74.2%(1427/1924)、69.2%(1305/1885)(χ2=11.446,P<0.01)。九市儿童换牙年龄为6.00(95%CI:5.98~6.01)岁。换牙年龄的第3~97百分位变化范围为4.88~7.11岁。女童中位换牙年龄(5.94岁)早于男童(6.06岁);城区(5.94岁)早于郊区(6.05岁);北片(5.97岁)、中片地区(5.97岁)略早于南片地区(6.05岁)。已换牙儿童体重、身高、体质指数Z分值均高于未换牙儿童(0.35±1.17比0.03±1.13、0.32±1.00比0.03±1.02、0.23±1.16比0.04±1.13,t=20.81、21.67、12.09,P均<0.05)。与1995年相比,2015年5.0岁以后儿童换牙率明显提高,如城区男童6.0~<7.0岁组1995年为63.8%(1146/1796),2015年提高至74.2%(1427/1924)(χ2=46.748,P<0.01);中位换牙年龄2015年较1995年提前0.24岁。结论九市4~7岁儿童换牙年龄女童早于男童,城区早于郊区,北、中片早于南片地区。换牙早晚与体格生长水平有关。近20年换牙年龄存在小幅提前趋势。
