Objective To explore the mechanism of Bufei Jiedu Granules in the treatment of methicillin-resistant Staphylococcus aureus(MRSA)chronic infection using network pharmacology;To verify it through animal experiments.Methods Active components and potential targets in Bufei Jiedu Granules were screened through the TCMSP database,and genes related to MRSA infection were retrieved through GeneCards,OMIM,DisGeNET,TTD,DrugBank and PharmGKB databases.The STRING database was employed to construct a protein-protein interaction network on common targets,and GO and KEGG pathway enrichment analysis were conducted to identify key signaling pathways for Bufei Jiedu Granules treatment of MRSA infection.The effects of Bufei Jiedu Granules on bacterial load and pathological changes in the lung,liver and kidney of MRSA chronic infection mice models were evaluated through WT and T/B immune cell deficient Rag2-/-mouse animal experiments.The mRNA expressions of inflammatory factors(IFN-γ,IL-10)and immune checkpoints(PD1,TIM3)were detected.Results Totally 54 active components related to Bufei Jiedu Granules were selected,and 50 potential targets related to MRSA infection were identified.118 signaling pathways significantly associated with MRSA infection were identified through GO and KEGG pathway enrichment analysis,in which the JAK-STAT signaling pathway,Th17 cell differentiation,and PD-L1 expression and PD-1 checkpoint pathway were closely related to cell activation and T cell differentiation.Animal experimental results indicated that Bufei Jiedu Granules could effectively reduce the bacterial load in organs and ameliorate the pathological damage in the chronic MRSA infection mouse model,increase the mRNA expression of IFN-γ in the lung tissue,and decrease the mRNA expressions of IL-10,PD1 and TIM3.Conclusion Bufei Jiedu Granules has the characteristics of multi-component and multi-target in the treatment of MRSA infection,and may be involved in adaptive immune activation to effectively treat chronic MRSA infection.

To analyze the epidemiological characteristics of COVID-19 in Fujian Province from the 49th week of 2022 to the 5th week of 2023,after further optimization of China's COVID-19 prevention and control measures on December 7,2022(the 49th week of 2022),this study used multi-dimensional surveillance data to dynamically assess population infection levels and their changing trends.The aim of the study was to provide a scientific basis for early warning of epidemic risk,medical resource allocation,and evalu-ation of socio-economic impact.A multi-source data surveillance system was constructed,encompassing surveillance of fever clinics at medical institutions(weekly collection of visits,positive nucleic acid and antigen test results,inpatients,and severe cases in sec-ondary or above hospitals),population nucleic acid test monitoring(weekly person-times and positivity rates of single-tube tests from the provincial system),sentinel hospital monitoring(weekly proportion of influenza-like illness visits at 18 sentinel hospitals and re-lated viral testing data),and monitoring of novel coronavirus variants(weekly systematic collection of genomic sequences of local and imported cases).Line charts were plotted weekly,and time series analysis,molecular epidemiological methods,and an improved SEIAR model were used to simulate epidemic spread.During the study period,the COVID-19 epidemic in Fujian Province exhibited three distinct stages.In the infection peak stage(52nd week of 2022),the provincial fever clinic visits reached 606 893 person-times,and a 49.2%positivity rate in population single-tube nucleic acid tests and 63.8%positivity rate in sentinel hospital monitoring were observed.In the medical load peak stage(2nd week of 2023),274 460 inpatients and 28 487 severe cases were recorded.In the epidemic decline stage(4th to 5th weeks of 2023),fever clinic visits decreased by 96.3%with respect to the peak,the single-tube nucleic acid test positivity rate decreased to 6.3%,and the sentinel hospital COVID-19 nucleic acid test positivity rate was 6.4%.All 508 sequenced local cases were Omicron variants,predominantly BA.5.2 and its sub-lineages(67.4%).Among 56 imported se-quenced cases,BA.5.2 and its sub-lineages accounted for 50.0%,and 16.1%comprised nine variants of interest including XBB and BQ.The model predicted the infection peak in the 52nd week of 2022,whereas the hospitalization peak lagged by approximately 10.6 days.Multi-source data monitoring revealed a three-stage development of the COVID-19 epidemic in Fujian.The BA.5.2 strain was dominant during the epidemic.The combination of multi-source monitoring data and modeling provides important references for epi-demic prevention and control,and highlights the need to improve the monitoring system in follow-up.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To review literature on exercise-based pre-rehabilitation before surgery in patients with lung cancer,hence to provide a guidance for development of standardised programs for pre-rehabilitative exercise.Methods Following the Australian JBI Evidence-based Health Care Centre Scope Review guidelines,a comprehensive search was conducted across the databases of PubMed,Embase,Web of Science,CINAHL,CNKI,WanFang Data and SinoMed.The search covered the inception of databases to 29th February,2024.The retrieved literature was then screened and relevant information was extracted.Results A total of 20 articles were included in this review.Exercise-based pre-rehabilitation for lung cancer patients was mainly divided into single-modality pre-rehabilitation and multimodal pre-rehabilitation(exercise combined with interventions in nutrition,psychology and health behaviour).The period of intervention for exercise-based pre-rehabilitation was typically 2-3 weeks before surgery,with 3-5 sessions per week.The outcome indicators mainly included respiratory function,capacity of physical activity,quality of life,psychological status and postoperative complications.Conclusion The preoperative exercise-based pre-rehabilitation before surgery for the patients with lung cancer is feasible and effective in enhancing physical function of the patients.Further studies can focus on the development of patient-centred standardised exercise pre-rehabilitation programs.

Objective To analyze the effect of Hedysari Radix Chinese herbal pieces treatment in acute inferior myocardial infarction patients undergoing percutaneous coronary intervention(PCI).Methods A total of 200 patients with acute inferior myocardial infarction undergoing emergency PCI admitted to department of cardiology of Shijiazhuang People's Hospital from March 31,2020 to March 31,2023 were selected as the study objects.The patients were randomly divided into a control group and a treatment group according to a digital random table method.The control group received routine treatment after PCI,and the patients drank 500 mL of warm water in the morning and afternoon every day,continuing this regimen for up to 30 days post-surgery.The treatment group took 10 g of Hedysari Radix Chinese Herbal pieces in 500 mL of boiling water in the morning and afternoon,soaking it and drinking it coolly and temperately,continuing to take it until 30 days after surgery.Blood pressure,Dopamine dosage,and duration were observed in all patients on 1-5 days after surgery.Major adverse cardiovascular event(MACE),such as cardiac death,myocardial infarction,heart failure,and re-admission were tracked in all patients within 30 days,and adverse reactions and clinical symptom improvement were followed up,using the somatic self-rating scale(SSS).Results The total Dopamine dose in the treatment group was significantly lower than that in the control group(mg:960.4±287.9 vs.1 160.4±610.5,P<0.05),and the duration of use was significantly shorter than that in the control group(hours:60.7±16.9 vs.71.6±20.4,P<0.05).The systolic blood pressure in the treatment group was significantly higher than that in the control group at 1 day after PCI[mmHg(1 mmHg≈0.133 kPa):96.8±19.5 vs.90.2±11.1,P<0.05],until 5 days after PCI(mmHg:106.3±14.4 vs.99.7±13.9,P<0.05),while the changes in diastolic blood pressure were not significant in both groups.The incidence of MACE in the treatment group was significantly lower than that in the control group within 30 days after PCI[4.0%(4/100)vs.13.0%(13/100),P<0.05],and the SSS score was also significantly lower than that in the control group(31.56±11.58 vs.40.72±18.67,P<0.05).Conclusion The effect of Hedysari Radix Chinese herbal pieces treatment can significantly improve clinical efficacy without significant adverse reactions.

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.
