A meta-analysis for Lianhua Qingwen on the treatment of Coronavirus disease 2019 (COVID-19)

BackgroundTraditional Chinese medicine (TCM) has been proven to played a great important role on the treatment of COVID-19. As one of the drugs recommended in Chinese guidelines, Lianhua Qingwen Granules or Capsules (LQ) are widely used.This systematic review and meta-analysis amis to evaluate the clinical efficacy of LQ on the treatment of COVID-19.MethodsSeven databases (PubMed, EMBASE, CENTRAL, CNKI, VIP, CBM and Wanfang) were searched to include all appropriate clinical trials that explore the efficacy of LQ on the treatment of COVID-19.ResultA total of 3 trials including 245 COVID-19 patients were eventually enrolled.Compared with the control group,the LQ group showed great significant difference on reducing the rate of clinical change to severe or critical condition[RR = 0.38, 95 %CI (0.17,0.85), P < 0.05]and the fever time (SMD =-0.57,95 %CI (-0.96,-0.17), P<0.05),as well as the significant improvement on the disappearance rate of the clinical symptoms: fever [RR = 1.36,95 %CI (1.14,1.61), P < 0.05],cough[RR = 1.99,95 %CI (1.39,2.86), P < 0.05],fatigue[RR = 1.52,95 %CI (1.15,2.01), P < 0.05] and anhelation [RR = 4.18,95 %CI (1.99,8.81), P < 0.05], but no significance on expectoration[RR = 2.46,95 %CI (0.81,7.51), P < 0.05].ConclusionThe clinical application of LQ on the treatment of COVID-19 has significant efficacy in improving clinical symptoms and reducing the rate of clinical change to severe or critical condition. Nevertheless, due to the limited quantity and quality of the included studies, more and higher quality trials with more observational indicators are expected to be published.     

中医药干预新型冠状病毒肺炎临床研究方案分析

对中医药防治新型冠状病毒肺炎临床研究方案注册情况进行分析,为提高相关研究设计质量提供参考和建议。检索中国临床试验注册中心网站(www.chictr.org.cn)以及美国临床试验注册中心网站(clinicaltrials.gov),以新型冠状病毒肺炎、2019-nCoV等为检索词,检索新型冠状病毒肺炎中医药相关临床研究方案。按照纳入排除标准筛选文献,并提取研究注册时间、研究目的、研究类型、申办单位、研究对象、样本量、干预措施、评价指标等数据,采用描述性分析方法。共纳入新型冠状病毒肺炎中医药相关研究方案49个,研究负责单位以湖北、北京、浙江等地医院或高等院校为主。研究具体实施单位属地集中在湖北、广东、浙江、河南等地医院。研究设计以干预性试验研究为主(共40个),其中随机平行对照研究30个,非随机对照试验7个,单臂研究2个,连续入组1个;观察性研究6个;卫生服务研究2个;预防性研究1个。总样本量30562例,单个研究样本量最大20000例,最小30例。49个方案的研究对象包括健康人群(3个)、隔离观察人群(1个)、疑似病例(10个)、确诊病例(31个)、康复期病例(4个)。31个拟纳入确诊病例的研究方案中,有16个研究未明确病情分级,3个研究明确排除危重症,4个研究纳入普通型,2个研究纳入轻型、普通型或重型,1个研究纳入轻型和普通型,1个研究纳入普通型或重型,3个研究纳入重型,1个研究纳入重症或危重症。评价的干预措施包括中成药(连花清瘟胶囊/颗粒、藿香正气滴丸/口服液、八宝丹、固表解毒灵、金蒿解热颗粒、复方鱼腥草合剂、金叶败毒颗粒、疏风解毒胶囊、双黄连口服液、痰热清注射液、血必净注射液、热毒宁注射液、喜炎平注射液)、汤药、太极拳疗法。主要疗效指标以退热时间、临床症状缓解、新型冠状病毒核酸转阴、重症转化率、胸部CT影像为主。结果表明中医药防治新冠肺炎的临床研究响应快速,当前注册方案涵盖了疾病预防、治疗和康复全过程。但存在人群定义不清,研究目标不明确,干预方案需要细化,疗效评价指标需要优化等问题;另外,需要考虑疫情救治的实际困难和工作负担,在符合医学伦理条件下,优化流程,提高研究方案的可操作性。

Correlates of Mental Illness and Health Categories among Older Adults in China: An Empirical Study Based on the Two Continua Model

Objective: Keyes’ two continua model is a useful concept in which mental health and mental illness exist on two separate axes. Based on this model, this study examined the prevalence and correlates of three mental health categories among older adults in China.

Methods: Cross-sectional data were derived from Wave 1 of the Study on Global AGEing and Adult Health. Participants were categorized into complete mental health (CMH), complete mental illness (CMI), and moderate mental health (MMH) groups. Multinomial logistic regressions were used.

Results: The prevalence of CMH, CMI, and MMH in China was 18%, 16%, and 66%, respectively. Being female, unmarried, younger, and feeling unhealthy were more likely to result in placement in the CMI category. Employment, education, and cognitive function were identified as important protective factors of CMH. Age, income, urban or rural residence, and physical function difficulty were associated with all three categories.

Discussion: We demonstrated the utility of the two continua model in identifying mental health needs in Chinese contexts. The findings suggest that future policy reforms and clinical interventions should establish a more comprehensive mental health category as a screening tool nationwide. The promotion of social engagement could play an important role in treating mental illness and improving positive mental health.     

Clinical observation on the effect of Chinese medicine-“TCM formula” intervention on recurrence and metastasis of triple negative breast cancer

ObjectiveThis study used a prospective cohort study to observe the effect of triple-negative breast cancer on the 2-year disease-free survival rate with or without “TCM formula”.MethodsFrom November 1 st, 2016, the first patient was enrolled in the cohort study. A total of 356 patients were enrolled on January 30, 2019. Among them, 154 cases were followed up for 2 years. During the follow-up, there were 6 cases of shedding, so 6 cases were affected. A total of 148 cases were included in the analysis, including 73 in the exposed group and 75 in the non-exposed group. The exposed group was given “TCM formula” on the basis of standardized treatment, and the non-exposed group was treated with simple triple-negative breast cancer. The two groups visited each of the three months. The interview included safety examination (hematology and imaging). The endpoint was the difference in 2-year invasive disease-free survival between the exposed and non-exposed groups and the safety of the “TCM formula”.ResultsThere were 6 cases of shedding during the experiment and the shedding rate was 3.9 %. The 2-year rate of invasive disease-free survival in the exposed team was 88.7 % and the non-exposed group was 82.5 %. Logistic multivariate regression analysis predicted that “TCM formula” could reduce the disease-related recurrence and metastasis rate by 11 % (OR = 0.89, 95 % CI 0.37−0.956, P＜0.05). Through K–M survival analysis, TNBC patients with age ≤35 years and regional lymph node stage N1 may be the benefit group of “TCM formula”(P＜0.05). During the study, the incidence of total adverse events was 8.2 % in the exposed group, mainly manifested as stomach discomfort, diarrhea, and hepatocyte damage.Conclusion1. In the exposed group, the two-year rate of invasive disease-free survival increased by 6.2 % compared with the non-exposed group(P＞0.05). 2. According to K–M survival analysis, TNBC patients with age ≤35 years and regional lymph node metastasis to N1 may be potential beneficiaries of “TCM formula”. 3. “TCM Formula” is safe and tolerable to most patients.
