OBJECTIVE:To improve the quality standard for Ganmao shangfengke tea. METHODS:TLC was used to identify the Saposhnikovia divaricata and Glycyrrhizae Radix et Rhizoma in the preparation. HPLC was used to determine the content of magnolol and honokiol:the column was Phenomenex Luna C18 with mobile phase of methanol-water(77:23,V/V)at a flow rate of 1.0 ml/min,detection wavelength was 294 nm,column temperature was room temperature,and the injection volume 5 μl. RE-SULTS:The TLC spots of S. divaricata and Glycyrrhizae Radix et Rhizoma were clear and well separated. The linear range was 3.13-100.2 μg(r=0.9999) for magnolol and 3.05-97.6 μg(r=0.9999) for honokiol;RSDs of precision,stability and accuracy tests were lower than 2%;recoveries were 98.2%-99.5%(RSD=0.5%,n=6)and 98.6%-99.6%(RSD=0.4%,n=6),respective-ly. CONCLUSIONS:The improved standard can be used for the quality control of Ganmao shangfengke tea.

To explore the clinical effect of alendronate combined with Jintiange capsules in the treatment of postmeno-pausal osteoporosis ( PMOP) . Methods:Ninety-eight cases of PMOP patients were randomly divided into three groups. The combina-tion treatment group (34 cases) was treated with alendronate tablets combined with Jintiange capsules, while the control group A (32 cases) and the control group B (32 cases) was respectively treated with alendronate tablets and Jintiange capsules, and the treatment course was six months. The changes of the clinical symptom score, bone mineral density ( BMD) , serum calcium, serum phosphorus, AKP, hepatorenal function and so on before and after the treatment were recorded. Results:After the six-month treatment, the clinical symptom score of the treatment group was much better than that in the two control groups(P<0. 05). BMD in the three groups was in-creased after the treatment(P<0. 05), and the increase in the treatment group was more notable than that in the two control groups(P<0. 05). Conclusion:Alendronate combined with Jintiange capsules can effectively improve BMD and relieve clinical symptoms in the patients with PMOP, which is worthy of promoted application.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

Coronaviruses (CoVs), a family of enveloped positive-sense RNA viruses, are characterized by club-like spikes that project from their surface, unusually large RNA genome, and unique replication capability. CoVs are known to cause various potentially lethal human respiratory infectious diseases, such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the very recent coronavirus disease 2019 (COVID-19) outbreak. Unfortunately, neither drug nor vaccine has yet been approved to date to prevent and treat these diseases caused by CoVs. Therefore, effective prevention and treatment medications against human coronavirus are in urgent need. In the past decades, many natural compounds have been reported to possess multiple biological activities, including antiviral properties. In this article, we provided a comprehensive review on the natural compounds that interfere with the life cycles of SARS and MERS, and discussed their potential use for the treatment of COVID-19.
