Abstract:
As a complex and large microbial community colonized in the human body, the intestinal flora and its metabolites short-chain fatty acids (SCFAs) play an important role in participating in human metabolism, resisting pathogens, and regulating immune mechanisms. In recent years, many studies have found that the intestinal flora is closely related to bone metabolism. The intestinal flora is able to regulate bone metabolism and affect bone mass changes through various pathways such as absorption of nutrition, generation of SCFAs, regulation of immunity, and influence on body metabolism. The potential pathways and mechanisms by which intestinal flora affect bone mass changes were reviewed in this article in bone metabolism. The related study on Traditional Chinese Medicine that has effects in balancing intestinal flora for regulating bone metabolism was also introduced in order to provide new ideas for the prevention and treatment of osteoporosis, a disease related to bone metabolism.

Abstract:
Objective To investigate the effect and mechanism of astragaloside Ⅳ(AS-Ⅳ) activating ROCK/JNK to regulate autophagy in improving isoproterenol (ISO) induced myocardial fibrosis (MF) in mice. Methods The mice were randomly divided into control operation group (Control group), ISO induced myocardial fibrosis group (MF group), AS-Ⅳ treatment group (AS-Ⅳ group) and combination group of astragaloside IV and Y-33075 (ROCK inhibitor) (astragaloside IV+Y-33075 group). After repeated administration for 30 days. The serum levels of LDH, BNP, CTGF in each group were detected. The cardiac function was detected by ultrasound. Myocardial structure and tissue fibrosis degree in each group were detected by Sirius Red and Masson staining. Oxidative stress (ROS) levels in myocardial tissue of each group were detected by DHE staining and the expression of ROCK, JNK, Atg5, Beclin 1, and LC3 Ⅰ/Ⅱ in myocardial tissue were detected by Western blotting. Results Compared with AS-Ⅳ group, the EF value of AS-Ⅳ+Y-33075 group decreased and the degree of myocardial fibrosis increased (P<0.05). The serum level of LDH, BNP, CTGF increased and the level of ROS in myocardial tissue increased while the expression of ROCK, JNK, Atg5, Beclin 1, LC3 Ⅰ/Ⅱ decreased (P<0.05). Y-33075 could block the protective effect of AS-Ⅳ on myocardial injury induced by MF and inhibit the regulation of AS-Ⅳ on ROCK and JNK. Conclusion AS-Ⅳ could attenuate myocardial fibrosis in mice by activating ROCK/JNK signal and promoting autophagy.

Abstract:
Objective To explore the possible mechanism of Radix Paeoniae Alba on hepatic fibrosis based on network pharmacology. Methods Tcmsp database was used to screen the active components of Paeonia alba. With the help of PubChem and Swiss target prediction database, the potential action targets of the effective components of Paeonia Alba were predicted. GeneCards and OMIM databases were used to screen the corresponding targets of liver fibrosis, and venn2.1.0 was used to obtain the common targets of white peony and liver fibrosis. Cytoscape 3.9.0 software was used to build the network diagram of “white peony - active ingredients - intersection target - liver fibrosis” and to predict the main active sites. String database was used to draw the PPI network. Go analysis of effective targets and enrichment analysis of KEGG in pathway were performed by David database. Results Six effective components, 213 targets of Paeonia Alba and 155 hepatic fibrosis targets were screened. There were 49 targets of Radix Paeoniae Alba in the treatment of liver fibrosis. The main active ingredients are kaempferol, paeoniflorin, mairin and β-Sitosterol. Go enrichment analysis showed 269 biological processes, 30 cell compositions, 64 molecular functions, and 67 pathways in KEGG pathway enrichment analysis. Conclusion The mechanism of anti-hepatic fibrosis of Radix Paeoniae Alba has been preliminarily studied through network pharmacology, which shows that Radix Paeoniae Alba has multi-component, multi-target, and multi-channel effects, and provides reference for further experimental research.

Abstract:
Objective To prepare a sustained-release membrane with longer adhesion time and dissolution time, and compare it with the commercially available oral ulcer membrane. Method Adhesion strength, adhesion time, swelling coefficient, dissolution time, etc. were used as the inspection indicators, and a combination of single factor inspection and analytic hierarchy process were used to screen the membrane -forming materials. The dispersion method of clotrimazole, ornidazole and borneol were investigated to prevent the drug from seed out. The method of combining orthogonal experiment and analytic hierarchy process were used to optimize the dosage of CMC-Na, PVA-1788 and glycerin; and the commercial products were compared. Results Through single-factor investigation and orthogonal experiment, the optimal ratio of excipients was selected as CMC-Na∶PVA-1788∶glycerol (3∶1∶0.08). The water-insoluble component clotrimazole, ornidazole and borneol were treated by precipitation in liquid with good effect. The best method was used to prepare the membrane. The adhesion strength was 102 g. The adhesion time was 55 min. The swelling coefficient was 1 939.52. The average dissolution time was 110 min. The appearance was white and the surface was free of bubbles, soft and elastic. The membrane forming time at 60 ℃ was 300 min and the demolding effect was better which could be completely peeled off with moderate thickness. Conclusion The oral ulcer membrane developed in this method has good appearance, comfortable use, strong adhesion, long adhesion time and dissolution time, and could stay on the ulcer surface for a long time to form physical isolation, and slowly release the drug during the dissolution process, which could play the role of long-term pain relief, antibacterial, anti-inflammatory and promote healing effects on oral ulcers.
