Efficacy and safety of Lianhuaqingwen capsules in high-risk common type COVID-19 pneumonia:A multicenter retrospective study

Objective:To evaluate the clinical safety and efficacy of Lianhuaqingwen(LHQW)capsules in patients with high-risk common type COVID-19 pneumonia.Methods:A retrospective multicenter study on 383 high-risk common type COVID-19 pneumonia cases was conducted.Patients were categorized as the standard treatment(SDT)group(n=168)and the LHQW+SDT group(n=215).The primary endpoint was the rate of symptom(fever,fatigue,coughing)recovery and the secondary endpoints included the time to symptom recovery,the proportion of patients with improvement in chest CT images,the proportion of patients with clinical cure,the timing and rate of negative conversion of SARS-CoV-2 RNA assay.Results:The recovery rate was significantly higher in the LHQW+SDT group as compared with the SDT group(89.7%vs.72.0%,P<0.01).The combined use of LHQW+SDT also showed shorter time for symptom recovery,as well as shorter time for individual symptom of fever,fatigue and coughing recovery than use of SDT alone.A higher proportion of patients in the LHQW+SDT group with improvements in chest CT images and clinical cure(77.7%vs.57.1%,P<0.01)but the proportion of patients deteriorating to severe cases(1%vs.25%,P<0.01)in this group was significant lower than those in the SDT group.No significant difference in negative conversion rate of viral assay results was observed(76.8%vs.75.0%,P>0.05).No serious adverse events were reported.Conclusions:LHQW capsules could be recommended to ameliorate clinical symptoms and reduce the rate of deteriorating to severe cases for high-risk common type COVID-19 pneumonia.

A Common Fixed Point Theorem for Compatible Mappings of Type （K） in Intuitionistic Fuzzy Metric space

The purpose of our paper is to obtain a common fixed point theorem for two pairs of self-mappings of compatible of type （K） in a complete intuitionistic fuzzy Metric space with example. Our result generalized and improves similar other results in literature.

Effectiveness and Safety of Baidu Jieduan Granules for COVID-19: A Retrospective Observational Multicenter Study

Objective: To evaluate the effectiveness and safety of Baidu Jieduan Granules(BDJDG) to treat common type coronavirus disease 2019(COVID-19). Methods: This multicenter, retrospective, and observational clinical trial included 230 common COVID-19 patients in Leishenshan, Huangshi, and Laohekou Hospitals in Wuhan from January 21 to March 26, 2020. The included patients were further divided into two subgroups according to the use of supplemental oxygen, mild and moderate groups. During the first 14 d of hospitalization, all patients were administered BDJDG combined with conventional Western medicine, and observed for continuous 28 d. Primary outcomes were disease progression rate and discharge rate. Secondary outcomes included negative conversion time of nucleic acid, hospitalization duration, clinical symptom subsidence time, and symptom regression rate. Results: A total of 230 common COVID-19 patients were analyzed(138 in moderate group and 92 in mild group). By day 28, the disease progression rate was 4.3% and the discharge rate was 95.7%. All mild cases recovered and were discharged from hospital. The median negative conversion time of nucleic acid of all 230 COVID-19 patients was 12 d [inter-quartile range(IQR) 3.5–17], the median hospitalization duration was 15 d(IQR 12–20). The median time to fever, cough, and fatigue recovery was 4 d(IQR 2–6), 8 d(IQR 5–12), and 8 d(IQR 5–11), respectively. The recovery rate of fever, cough, and fatigue was 94.6%, 90.5%, and 93.5%. The median time to clinical improvement was 12 d(IQR 10–17). Compared with the baseline, total leukocyte, neutrophil, lymphocyte, and platelet counts were all increased significantly on days 7 and 14(P<0.01). C-reactive protein markedly increased on day 3 and significantly decreased on days 7 and 14(P<0.01). No serious adverse events occurred during treatment. Conclusion: BDJDG may be effective and safe for treatment of common type COVID-19.(Registration No. ChiCTR2000030836)
