ABSTRACT

Objective:To comprehensively analyze the diagnosis and treatment programs and prevention and treatment programs on tratidional Chinese medicine (TCM) for coronavirus disease-2019 (COVID-19), and to provide suggestions for further development of TCM clinical guidelines. Method:Diagnosis and treatment programs on TCM for COVID-19 pneumonia, as well as prevention and treatment programs, clinical practice guidelines and expert consensus, were retrieved till Feb 19, 2020. The information about TCM syndrome differentiation, state of disease, and TCM treatments (decoction and Chinese patent medicines) were extracted and analyzed. Result:A total of 24 TCM programs/guidelines were included containing 23 diagnosis and treatment programs or prevention and treatment programs and one rapid advice guideline. Of the 23 TCM programs, 14 programs described the classification of TCM syndromes and the stages of disease,22 programs described the composition of the TCM decoction; seven programs described how to add and subtract the herbs according to different TCM syndromes,17 programs described the weight/volume of the herbs of TCM decoctions, three programs described the decoction method,six programs described the usage and dosage of TCM decoction, two programs clarified the course of treatment; none of the 23 programs indicated the source of evidence. The TCM treatment within the rapid advice guideline was in reference to the fourth edition of the COVID-19 pneumonia TCM diagnosis and treatment program issued by the National Health Commission. A total of 41 Chinese patent medicines were recommended in 23 programs, of which 12 Chinese patent medicines were off-label recommended. Conclusion:In most TCM programs, TCM decoction and Chinese patent medicines are recommended based on TCM syndrome differentiation in combination with the state of disease, and the dosage of the TCM decoctions are clearly described. Some Chinese patent medicines in the TCM programs are off-label recommended. Expert experience and opinions are valued when developing TCM programs/ guidelines. All of these provide reference for developing TCM programs/guidelines in future.

ABSTRACT

Objective:To observe the effect of serum of kidney Yang deficiency rats on the expression of β-catenin,osteoprotegerin(OPG) and nuclear transcription factor-κB receptor activator ligand (RANKL) in the co-culture system and regulatory of icariin on it, and to explore the possible mechanism of inducing osteoporosis.Method:The 16 male SD rats were randomly divided into blank group and model group, 8 rats in each group. 10 mL·kg-1 adenine was administrated to stomach to establish kidney yang deficiency model. Serum was separated and extracted after the model was established successfully. Isolation and culture of osteoblast(OB) and osteoclast(OC) in vitro, OB was observed and identified by alkaline phosphatase(ALP),alizarin red and Giemsa staining, OC was identified by tartrate resistant acid phosphatase(TRAP) staining, OB-OC co-culture system was established in transwell cell, icariin group(100 μmol·L-1), blank group, icariin(100 μmol·L-1) + serum group, serum group and Dickkopf1(DKK-1) drug(100 μg·L-1) were set up in group , 2 days after intervention of co-culture system, OC was counted, ALP and TRAP in supernatant were detected by microplate enzyme labeling, and the expression of OPG,β-catenin and RANKL in each group was detected by Western blot.Result:Compared with blank group, the ALP activity,β-catenin and OPG protein expression in serum group were significant reduction (P<0.05), while the OC quantity, TRAP activity and RANKL protein expression were marked increase (P<0.05). Compared with serum group, ALP activity of icariin group decreased significantly (P<0.01), Compared with icariin group, ALP activity and OPG protein expression decreased (P<0.05), trap activity and RANKL expression increased (P <0.05) in icariin + serum group.Conclusion:The serum of kidney Yang deficiency rats can induce the occurrence of osteoporosis, and the mechanism of action may be through inhibition of ALP activity, down regulating the expression of β-catenin and OPG protein, increasing the activity of TRAP and the expression of RANKL protein.
