ABSTRACT
BACKGROUND:Excessive accumulation of uric acid in the body can lead to diseases such as hyperuricemia and gout,which is a risk factor for cardiovascular and renal dysfunction.Many sports medicine organizations at home and abroad advocate the formulation of exercise prescription to prevent and treat chronic diseases,but this method has not been effectively carried out in the prevention and treatment of hyperuricemia. OBJECTIVE:Based on an overview of the formation of hyperuricemia and the regulation of uric acid by exercise and its related mechanisms,to condense a program suitable for popular exercise to prevent and assist in the treatment of hyperuricemia,and to propose precautions to be taken when exercising for patients with different stages of hyperuricemia. METHODS:PubMed and CNKI were searched for relevant literature published before October 2023 using the keywords of"uric acid,gout,aerobic exercise,strength training,high-intensity interval training,obesity"in English and Chinese,respectively.Initial screening was done by reading the titles and abstracts to exclude repetitive studies and literature with irrelevant content,and finally 64 papers were included for review. RESULTS AND CONCLUSION:The formation of hyperuricemia is caused by excessive synthesis of uric acid by the liver,insufficient excretion by the kidneys,or both.Exercise can improve the uric acid level in the body by regulating the activity of antioxidant enzymes,the expression of uric acid excretion protein and lipid metabolism.Aerobic exercise,strength training,high-intensity intermittent exercise can effectively regulate uric acid levels,reduce inflammation,promote the expression of uric acid excretion protein and lipid metabolism,and achieve good results in the prevention and treatment of hyperuricemia.Currently,there is a lack of research on the mechanisms underlying direct regulation of uric acid levels by exercise,and future studies need to explore in greater depth the possible mechanisms of regulation of uric acid levels by exercise and refine the effects of different exercise modalities on patients with different characteristics of hyperuricemia.
ABSTRACT
Silk-based biomaterials are featured with excellent mechanical properties, good biocompatibility and biodegradability, which contribute to their potential applications in biomedical field. The current recognition of silk protein materials in structure and function provides a basic theory for the transformation of silk protein into new types of biomaterials. In addition, exogenous sequences encoding new peptide or structural domain can be inserted into the maternal gene sequences encoding silk proteins through genetic engineering technology to synthesize novel silk-based biomaterials with unique functions. This review summarizes the current trend and development perspective of genetically engineered functional silk-based materials for biomedical applications.

As a receptor tyrosine kinase, mesenchymal to epithelial transition factor (MET) is the membrane receptor for hepatocyte growth factor (HGF), which is related with a series of biological functions, such as cell proliferation, progression, apoptosis, metastasis and morphological changes. As research continues, MET is amplified or overexpressed in a wide range of human cancers and closely related with worse prognosis. Therefore, various MET inhibitors are currently being developed as potential treatments for a variety of cancers. Based on our current study we summarize the existing knowledge on structure, biological function and its inhibitors of MET and provide a data phase for future researchers.

ABSTRACT
Objective To investigate physical activity in patients with type 2 diabetes mellitus and to analyze its influencing factors,in order to provide references for the prevention and control of disease.Methods A total of 469 cases of patients with type 2 diabetes mellitus were enrolled in this study.The basic information,such as gender,age and so on,and situation of physical activity,including work,housework,transportation and entertainment,were surveyed via questionnaire.Results The total amount of physical activity of patients with type 2 diabetes mellitus in this survey was (1 581.59±743.65)MET-min per week,were mainly contributed from entertainment and housework which was (940.83 ± 547.06) and (407.20 ± 226.63)MET-min per week respectively.The amount of physical activity of patients in different age,occupation,duration of illness and BMI,and patients with or without other chronic diseases were significantly different (P＜0.05).Under 45 years old,being on-the-job,with other chronic disease were risk factors for lack of physical activity in patients with type 2 diabetes mellitus (P＜0.05),while aged 45-＜60 years old,light or normal weight was the protection factors of sufficient physical activity in patients with type 2 diabetes mellitus (P＜0.05).Condusion The overall physical activity of patients with type 2 diabetes mellitus is on the medium level,and its main types are entertainment and housework.Patients under 45 years old,being on-the-job,with other chronic diseases have higher risk of lacking physical activity.
ABSTRACT
Objective To explore the clinical efficacy of Baihu decoction combined with insulin on type 2 diabetes with acute hyperglycemia patients.Methods A total of 86 cases of type 2 diabetes with acute hyperglycemia patients were randomly divided into experimental group (n=43) and control group (n=43).Two groups of patients underwent conventional exercise and diet adjustment intervention, control group was treated with insulin, continuous injection of 14d, experimental group was treated with Baihu decoction based on control group, 7d was taken for one courses, two course in all.The clinical symptoms of the two groups were compared, and the FPG, 2hPBG, HbAlc levels was detected in two groups pre-and post-reatment, the serum IL-6, hs-CRP, TNF-α, LP, APN, Cor were detected by enzyme linked immunosorbent assay method.Results The total effective rate was 91.7%in experimental group, higher than 76.7% in control group(P<0.05).After treatment, FPG, 2hPBG, HbAlc, IL-6, hs-CRP, TNF-αlevels in two groups were all significantly decreased (P<0.05), and those indexes in experimental group were significantly lower than those in control group (P<0.05).After treatment, APN and LP were significantly decreased, Cor was significantly increased in two groups(P<0.05), and the LP and APN in experimental group were significantly lower and Cor was significantly higher than that in control group (P<0.05).Conclusion Baihu decoction combine with insulin can significantly improve the clinical symptoms in type 2 diabetes with acute hyperglycemia patients, reduce the level of blood glucose and cytokines, and its mechanism may be relate to the increase APN level, reduce the LP and Cor levels.

ABSTRACT
<p><b>OBJECTIVE</b>To study synthesis of baicalin-copper and baicalin-aluminium complex and its antimicrobial, anti-tumor activity and anti-tumor effect against macrophages.</p><p><b>METHOD</b>Baicalin was reacted with metallic salt under a weak base condition to produce baicalin-copper and baicalin-aluminium complex. Baicalin and its synthesized complex were detected for antimicrobial activity against Staphylococcus aureus, Hay bacillus, Escherichia coli, Salmonella and Candida albicans by twofold broth dilution technique. Their anti-tumor activity against A549 and IC50 of HepG2 cells and anti-tumor effect against macrophages were detected by the MTT. And their phagocytic effect on macrophages was determined by the neutral red assay.</p><p><b>RESULT</b>The yields of baicalin-copper and baicalin-aluminium complex were 73.93% and 91.08%, respectively. The minimum inhibitory concentration (MIC) value against Staphylococcus aureus, Hay bacillus, Escherichia coli, Salmonella and Candida albicans was 0.0004, 0.0009, 0.0004, 0.0009, 0.000 4 mol x L(-1) for baicalin-copper complex and 0.0011, 0.0011, 0.0011, 0.0011, 0.0005 mol x L(-1) for baicalin-aluminium complex. The IC50 values against A549 and HepG2 cells were 89.6, 22.6 micromol x L(-1) for baicalin-copper complex, and 138.8, 97.2 micromol x L(-1) for baicalin-aluminium complex. The inhibitory ratio of macrophage on A549 cell was 43.52%, 80.89%, 52.66%, respectively, after the macrophages were stimulated by baicalin, baicalin-copper and baicalin-aluminium complex at a concentration of 160 micromol x L(-1).</p><p><b>CONCLUSION</b>The acute toxicity test in mice showed that the complex was nontoxic to mice. Baicalin-copper complex showed the highest antimicrobial, anti-tumor activity, and the strongest effect on the anti-tumor activity of macrophage, while baicalin showed the lowest activities compared with baicalin-copper and baicalin-aluminium complex.</p>
