We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

Objective To investigate the protective effect of FLPNF and the improvement of glucose-stimulated insulin secretion against dexamethasone-induced apoptosis of islet cells. Methods INS-1 cells were treated with oligopeptide FLPNF and dexamethasone, either separately or in combination. Proliferation of INS-1 cells in each group was assessed with CCK-8 assay and the insulin secretion stimulated by glucose was detected by ELISA. The apoptotic condition of the cells was observed and assessed with TUNEL and the apoptosis rate of each group was detected using flow cytometry. The expression of major target protein molecules related to apoptosis and Glut2 was detected by Western blotting analysis. Results Dexamethasone inhibited the growth of INS-1 cells in the group treated with dexamethasone. Cell damage was obvious with observable nuclear shrinkage and nuclear rupture. In addition, apoptosis rate was found to be 40.6％±2.4％. The expression of the apoptosis-related protein Bcl-2 and Glut2 was significantly reduced, whereas that of Bax and caspase-3 was significantly increased. After the combined treatment of oligopeptide FLPNF and dexamethasone, the results were reversed, and the apoptosis rate declined to 27.2％±2.0％ (P ＜ 0.001), cell morphology was improved, and the expression of apoptosis-related protein molecules of islet cells and protein Glut2 was significantly improved. Conclusion FLPNF has the ability of protecting islet cells from dexamethasone-induced apoptosis and improving the glucose-stimulated insulin secretion of islet cells.

OBJECTIVE:To observe the effects of Salvia miltiorrhiza-volatile oil of Dalbergia odorifera on blood lipid and blood coagulation system in coronary heart disease myocardial ischemia miniature swine with blood stasis syndrome. METHODS:A total of 18 swine were randomly divided into sham operation group (routine feed),model group (routine feed) and S.miltiorrhiza-volatile oil of D. odorifera group(1 g/kg S. miltiorrhiza+0.1 mL/kg oil of D. odorifera,mixing administration),for consecutive 8 weeks. At 4th week,coronary heart disease myocardial ischemia model of blood stasis syndrome was established by Ameriod coarctation ring implantation in other 2 groups except for sham operation group. At 8th week,the syndrome of the model was observed according to coronary angiography and the macroscopic indications. At 2th,6th,8th week,intravenous blood was collected to test the serum levels of TC,TG,LDL-C,HDL-C,apolipoprotein A1(apoA1),apoB,PT,APTT,TT and FIB in miniature swine. RESULTS:At 6th,8th week,compared with sham operation group,serum levels of TC,TG,LDL-C,apoB and FIB were increased in model group,while PT,APTT and TT were shortened and the levels of HDL-C and apoA1 were decreased,with statistical significance(P<0.05 or P<0.01). Compared with model group,the serum levels of TC,TG,LDL-C and apoB were decreased in S. miltiorrhiza-volatile oil of D. odorifera group,while PT,APTT and TT were prolonged and the levels of HDL-C and apoA1 were increased, with statistical significance (P<0.05 or P<0.01). CONCLUSIONS: The S.miltiorrhiza-volatile oil of D. odorifera could reduce blood lipid and improve blood coagulation system index disorder in coronary heart disease myocardial ischemia miniature swine with blood stasis syndrome.
