Effects of Tanreqing Capsule on the negative conversion time of nucleic acid in patients with COVID-19:A retrospective cohort study

Objective:Traditional Chinese medicine plays a significant role in the treatment of the pandemic of coronavirus disease 2019(COVID-19).Tanreqing Capsule(TRQC)was used in the treatment of COVID-19 patients in the Shanghai Public Health Clinical Center.This study aimed to investigate the clinical efficacy of TRQC in the treatment of COVID-19.Methods:A retrospective cohort study was conducted on 82 patients who had laboratory-confirmed mild and moderate COVID-19;patients were treated with TRQC in one designated hospital.The treatment and control groups consisted of 25 and 57 cases,respectively.The treatment group was given TRQC orally three times a day,three pills each time,in addition to conventional Western medicine treatments which were also administered to the control group.The clinical efficacy indicators,such as the negative conversion time of pharyngeal swab nucleic acid,the negative conversion time of fecal nucleic acid,the duration of negative conversion of pharyngeal-fecal nucleic acid,and the improvement in the level of immune indicators such as T-cell subsets(CD3,CD4 and CD45)were monitored.Results:COVID-19 patients in the treatment group,compared to the control group,had a shorter negative conversion time of fecal nucleic acid(4 vs.9 days,P=0.047)and a shorter interval of negative conversion of pharyngeal-fecal nucleic acid(0 vs.2 days,P=0.042).The level of CD3+T cells increased in the treatment group compared to the control group([317.09±274.39]vs.[175.02±239.95]counts/l L,P=0.030).No statistically significant differences were detected in the median improvement in levels of CD4+T cells(173 vs.107 counts/l L,P=0.208)and CD45+T cells(366 vs.141 counts/l L,P=0.117)between the treatment and control groups.Conclusion:Significant reductions in the negative conversion time of fecal nucleic acid and the duration of negative conversion of pharyngeal-fecal nucleic acid were identified in the treatment group as compared to the control group,illustrating the potential therapeutic benefits of using TRQC as a complement to conventional medicine in patients with mild and moderate COVID-19.The underlying mechanism may be related to the improved levels of the immune indicator CD3+T cells.

Short Term Efficacy of Entecavir in the Treatment of Decompensated Chronic Hepatitis B Cirrhosis

Objective:To explore the effect of entecavir on patients with decompensated chronic hepatitis B cirrhosis.Methods:From October 2007 to December 2019,100 patients with decompensated chronic hepatitis B cirrhosis who were treated in our hospital were selected to carry out this study.The clinical data of the patients were analyzed.According to whether entecavir treatment was carried out,100 patients were divided into two groups,50 cases in the control group and 50 cases in the observation group.The control group was treated with conventional drugs,and the observation group was treated with entecavir.Liver function indexes,liver fibrosis indexes,HBV-DNA negative conversion rate and incidence of adverse reactions were compared between the two groups.Results:Compared with the control group,the liver function indexes of the observation group were lower,P<0.05;Compared with the control group,the observation group was better,P<0.05;The negative rate of HBV-DNA in the observation group was lower than that in the control group(P<0.05);There was no difference in the incidence of adverse reactions between the two groups,P>0.05.Conclusion:Entecavir can not only improve the liver function,but also enhance the shortterm treatment effect,without increasing adverse reactions,and has high safety,which is worthy of recommendation.
