In the process of accelerating the construction of a strong country in health and sports in China， the mode of promoting health has shifted from passive health to active health. Guided by the concept of “active health”， there is a new understanding of the relationship between sports， health， and medical care. The integration of sports and medicine is a concrete manifestation and implementation of the concept of “active health”， and an important measure to implement the Healthy China strategy， which is regarded as an important strategy to promote public health reform. This article reviews the historical path of the integration of sports and medicine from its concept to practical implementation， and finds that China proposed the integration of sports and medicine relatively late， but it has become an intense focus of academic research； The sports and medical departments have launched guidelines for chronic disease exercise and standards related to exercise prescriptions， and local governments in China have explored diversified models of integrating sports and medicine； Under the institutional requirements of top-level design， the exploration of the “integration of sports and medicine” model is flourishing. There are currently problems in promoting the integration of sports and medicine， such as the lack of a “sports and medicine integration” system and a shortage of “sports and medicine integration” talents. Drawing on the international experience of integrating sports and medical services in other countries，We propose a development strategy of “concept first， government leading， and sports and medical cooperation”； We recommend institutional optimization such as improving medical insurance related systems， establishing certification， employment， and management systems for integrated sports and medical talents， and improving the training system for integrated sports and medical talents in universities； We also advocate propose a “dual wheel” promotion path of upgrading hospital rehabilitation centers and expanding community health centers， in order to provide reference for policy formulation and promote the integration of sports and medicine to play a greater role in China’s public health.

OBJECTIVE To compare the emergency specialist clinical pharmacist training programs between China and the United States， providing valuable insight for the development of specialized clinical pharmacist training in emergency departments within China. METHODS By reviewing the official website of the American Society of Health-System Pharmacists （ASHP）， the websites of some training institutions offering PGY2 emergency medicine （EM） residency programs in the United States， the official website of China’s National Health Commission， and the website of the Pharmaceutical Affairs Committee of the Chinese Hospital Association， relevant materials and data on the training of emergency medicine clinical pharmacists were collected. Microsoft Excel and NVivo software were utilized to analyze the implementation status of these training programs. Literature searches were conducted via Chinese （CNKI） and English （PubMed） databases， followed by screening， categorization， and thematic analysis aligned with research objectives. RESULTS As of now， there are 115 accredited PGY2 EM residency programs in the United States， which provide 120 specialized pharmacist training positions. These programs are distributed across 35 states and are hosted by a variety of institutions， including hospitals， medical centers， and universities. The predominant training model follows a hospital+acute care framework. Eligibility requirements for PGY2 EM residency programs include possession of a doctor of pharmacy （Pharm.D.） degree， pharmacist licensure， and completion of a PGY1 residency. The training standards are structured into three tiers： competency areas， competency goals， and learning objectives. The curriculum typically includes core rotations， elective rotations， and longitudinal training components. Assessment is conducted through a combination of formative and summative evaluations， with results categorized into four proficiency levels. In China， there is only one training base currently for emergency clinical pharmacist specialty training with an annual enrollment of three trainees. Applicant eligibility primarily involves requirements regarding academic degree， professional background， years of experience， and professional title. The training content covers four domains： general competency， clinical theoretical knowledge and skills， pharmacological knowledge and application， and clinical medication practice skills. The training process centers on rotations within emergency departments. Assessment methods include theoretical examinations， daily performance evaluations， and final completion assessments. CONCLUSIONS PGY2 EM residency programs in the United States emphasize inclusivity and professionalism in their implementation. Program admission involves a rigorous selection process， and they offer attractive incentive structures for trainees. The training content focuses on competency-based approaches and pragmatic applicability， while assessment methods are closely aligned with defined competence objectives. In contrast， specialist clinical pharmacist training in emergency medicine in China is currently in the exploratory and nascent stages. Admission criteria tend to be less stringent， and incentives for trainees are often insufficient. The training content appears relatively stereotyped and superficial， with assessment methods still primarily reliant on quantifiable metrics. In expanding and popularizing China’s emergency specialist clinical pharmacist training programs， it is essential to draw on advanced experiences from developed countries like the United States， particularly in areas such as training base distribution， application requirements， training content， and assessment methods. Aligned with the realities of emergency clinical practice in China， efforts should focus on enhancing program accessibility and training efficacy.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective To investigate the gray matter volume(GMV)changes and molecular basis underlying antipsychotic-induced weight gain(AIWG).Methods One hundred twenty-nine first-episode schizophrenia patients from October 2019 to December 2021 were enrolled in this study.Patients with≥7%weight gain(weight gain,WG)and patients with<3%weight changes(weight stable,WS)were studied.All patients underwent T1-weighted MRI scanning at baseline and after 8 week treatment.Transcriptome-neuroimaging correlations were used to investigate brain gene profiles from the Allen Human Brain Atlas and GMV changes induced by AIWG.Results Thirty-three patients with WG and 27 with WS completed the GMV measures.Compared with baseline,the WG group showed reduced GMV in right hippocampus,left basal ganglia,and right inferior parietal lobule,etc.and increased GMV in bilateral thalamus(P<0.05).The WS group showed reduced GMV in bilateral orbital gyrus,bilateral inferior frontal gyrus and bilateral hippocampus(P<0.05).These GMV changes in WG group were spatially correlated with expression levels of 354 genes,which were exclusively enriched in Cushing syndrome,neuroinflammation and glutamatergic signaling,and Pnoc+.Conclusion The study has demonstrated increased GMV in thalamus in schizophrenia patients with AIWG which may be associated with Cushing syndrome and Pnoc+.These findings may provide important insights into the molecular mechanisms of AIWG.

Objective A comparison of two method of establishing pressure ulcer rat models to determine which is the most suitable for experimental use.Methods 18 male SD rats were randomly divided into control(n=6),model A(n=6)and model B(n=6)groups.In the control group,iodophor treatment was given after hair removal at the simulated modeling site.In model group A,longitudinal compression was performed by simple deep-tissue foreign body implantation.In model group B,transverse compression was performed via the magnet compression method.The times required to complete the process and for each stage of pressure ulcer model establishment in each group were recorded.The general condition of the rats was observed,and the modeling rate,mortality rate,and infection rate were compared.Results By naked eye,we observed that the model A and model B groups gradually developed redness and swelling,ulceration,bleeding,exudation,and necrosis.Comparison of the whole time to produce pressure uler between model A and model B groups:the difference between the two groups was statitically significant(P＜0.05).Comparison of the time to produce pressure injury between Model A and Model B:The difference between the two groups at stage Ⅰ was not statistically significant(P＞0.05);the difference between the two groups at stage Ⅱ was statistically significant(P＜0 05);the difference between the two groups at stage Ⅲ was statistically significant(P＜0 05);the difference between the two groups at stage Ⅳ was statistically significant(P＜0 05).The mental and sports scores of the rats in the control group were significantly different from those in the model A and model B groups(P＜0.05).The general state of rats in the model group A was significantly different from that in the model B group,and coat color was dimer and activity decreased in the model group A.The modelling rate of rats in both model A and model B groups was 100％.The mortality and infection rates of the model group A were higher than those of the model group B,which were 33.34％and 16.70％,respectively.Conclusions Successful preparation of a four-stage model of pressure ulers in both modalities.The two method have both commonalities and distinct characteristics.The magnet compression method required less time,the rats were generally in good condition,and the mortality and infection rates were low;thus it is suitable for short-term intervention research.The simple deep-tissue foreign body implantation method took longer,required rats to have a certain level of tolerance,had high infection and mortality rates,and is more suitable for use for long-term observations of pressure ulcers.

Circular RNA(circRNA)represents a unique class of closed-loop structured non-coding RNAs involved in various biological processes such as cell proliferation,differentiation,and apopto-sis.They play a significant role in the development of numerous diseases,and also serve as poten-tial biomarkers and therapeutic targets.To explore the impact of circRNA on viral replication,this study performed an omics measurement and analysis of circRNA differential expression in MC38 cells infected with HY12 enterovirus.It was found that,following HY12 virus infection,the ex-pressionlevels of 570 circRNAs were upregulated,while 381 circRNAs were downregulated.A-mong the upregulated circRNAs,the significantly upregulated circRNA mmu_circ_0001083 was selected for further investigation into its association with HY12 infection and its impact on viral replication.The results indicated that after HY12 virus infection,the expression of host circRNA mmu_circ_0001083 significantly increased,and its expression level was dependent on the virus dos-age and time.Compared to normal MC38 cells infected with the HY12 virus,cells with knocked down expression of circRNA mmu_circ_0001083 showed reduced expression of the 2C protein and significantly lower viral titers.Conversely,after HY12 virus infection in MC38 cells with overexpressed circRNA mmu_circ_0001083,there was an increase in the expression of the 2C pro-tein and a significant rise in viral titers.These results suggest that the upregulation of host cir-cRNA mmu_circ_0001083 is significantly positively correlated with the replication of HY12 virus,meaning mmu_circ_0001083 plays a positive regulatory role in the replication of HY12.This find-ing lays a foundation for future in-depth studies on the regulatory mechanisms of circRNA on viral replication.

The NMGCF-19 strain is an E.coli strain isolated and identified in our laboratory from lambs manifesting severe diarrhea and meningitis.Previous analysis of the genome sequence of NMGCF-19 strain showed that the outer membrane protein A(ompA)gene was a potential viru-lent gene.In order to determine whether the ompA gene is associated with the pathogenicity of NMGCF-19 strain and the underlying mechanism,the NMGCF-19 strain with ompA knockout(NMGCF-19△ompA)was generated in this study using CRISPR/Cas9 technology and used to de-termine the role of ompA gene in mediating the encephalitis by NMGCF-19 infection and the un-derlying mechanism using the mouse model system.The results showed that the neuronal cell nec-rosis in the hippocampus in mice infected by NMGCF-19△ompA was significantly reduced and was not focal compared with that of mice infected with the wild-type NMGCF-19 strain.The number of bacteria in brain of mice infected by NMGCF-19 △ompA was significantly reduced in comparison to that of mice infected by NMGCF-19.Simultaneously,the mRNA and protein expression levels of the tight junction proteins ZO-1 and Occludin were both increased in mice infected by NMGCF-19 △ompA strain compared with the mice infected by NMGCF-19 strain.These results suggest that the ompA gene is a virulent gene and plays an important role in the invasion of the blood-brain barrier by NMGCF-19 strain in mice.
