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 explore the serological characteristics and genetic variant in a Chinese pedigree with Bw subtype.Methods:A 32-year-old female proband who had undergone prenatal examination on December 10, 2020 at the 960th Hospital of the PLA Joint Logistics Support Force and five members from her pedigree were selected as the study subjects. Peripheral blood samples were collected and subjected to ABO blood group phenotyping with serological methods and ABO blood group genotyping with fluorescent PCR. Genetic testing and haplotype analysis were carried out by direct sequencing of the entire coding region of the ABO gene in the proband and cloned sequencing of exons 1-7. Results:The blood type serology of the proband showed Bw, and the ABO blood type genotype determined by fluorescence PCR was B/O. The direct sequencing results showed that the proband had matched the ABO* O. 01. 01/ ABO* B. 01 genotype and carried a c. 1A>G variant. Cloned sequencing has confirmed the c. 1A>G variant to have occurred in the ABO* B. 01 allele. Family analysis revealed that the mother of the proband had an O blood type, her husband had a B phenotype, and the her three children had a normal B blood type. DNA sequencing showed that the two sons of the proband had a genotype of ABO* B. 01 and c. 1A>G/ ABO* B. 01. The daughter of the proband was ABO* O. 01. 01/ ABO* B. 01, whilst her mother was ABO* O. 01. 01/ ABO * O. 01. 02. The novel c. 1A>G variant sequence has been registered with the database with a number of MZ076785 1. Conclusion:The novel c. 1A>G variant of exon 1 of α- 1, 3 galactose aminotransferase gene probably underlay the reduced expression of B antigen in this pedigree.

Atypical anti-glomerular basement membrane(GBM)disease is rare,and the atypical anti-GBM disease with membrane hyperplasia lesion is even rarer.The treatment plan for it is not clear.This article reports a case of atypical anti-GBM disease with a negative anti-GBM antibody test,but renal tissue biopsy showed"glomerular membrane hyperplasia lesions with positive IgG linearity",which provides a reference for clinical diagnosis and treatment.The patient exhibited massive proteinuria,hematuria,edema,and renal impairment.After ruling out secondary factors,the patient was diagnosed with"atypical anti-GBM nephritis"by renal tissue biopsy,and was treated with glucocorticoids combined with cyclophosphamide,after which the patient developed a lung infection and acute left heart failure,and received regular hemodialysis treatment.Then the patient progressed to the stage of end-stage renal disease and continued to receive regular hemodialysis treatment.

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 explore the application effect of slope adjustment mattresses in the position management of pediatric intensive care unit (PICU) mechanically ventilated children, in order to seek methods for maintaining effective posture in clinical practice.Methods:This was a quasi-experimental study. In this study, the mechanically ventilated children in PICU of Hunan Children′s Hospital from January 1 to December 31, 2022 were selected by convenient sampling method and divided into control group ( n=21) and experimental group ( n=21) according to random number table. Children in control group used the hospital bed and the traditional posture management, and children in experimental group used the slope adjustment mattress for posture management. The comfort scores, mechanical ventilation time, PICU length of stay, postural decline, unplanned extubation and blood gas analysis index were compared between the two groups. Results:There were 21 cases were admitted in each group ultimately. In the control group, there were 10 males and 11 females, the age was (31.43 ± 27.01) months. There were 11 males and 10 females in the experimental group, the age was (24.57 ± 24.20) months. The comfort scores of the experimental group were (13.57 ± 0.93) and (12.52 ± 0.60) points at the 24 hour and 72 hour respectively; while the comfort scores of the control group were (16.05 ± 1.72) and (15.81 ± 1.66) points at the 24 hour and 72 hour respectively. There were significant differences between the two groups ( t=5.82, 8.52, both P<0.05). The mechanical ventilation time was (5.43 ± 2.48) d, the PICU length of stay was (9.29 ± 3.04) d, and the number of postural decline was (7.52 ± 2.06) times in the experimental group which was superior to control group (8.52 ± 4.65) d, (12.71 ± 6.76) d, (14.95 ± 6.86) times, the differences were significant ( t=2.69, 2.12, 4.75, all P<0.05). There were 0 case of unplanned extubation in the experimental group and 4 cases of unplanned extubation in the control group .The difference was significant ( χ2=5.97, P<0.05). For blood gas analysis, PaCO 2 on the second day were (56.90 ± 6.77) mmHg (1 mmHg=0.133 kPa) in the control group, and (48.67 ± 8.13) mmHg in the experimental group; PaO 2, oxygenation index, PaCO 2 on the third day were (91.19 ± 16.27), (278.19 ± 71.54), (51.62 ± 4.73) mmHg in the control group, and (110.43 ± 21.73), (347.33 ± 90.95), (40.24 ± 5.57) mmHg in the experimental group, the differences were significant ( t values were 7.50-51.00, all P<0.05). There were significant differences about blood gas analysis of time interaction, inter-group interaction, time and inter-group interaction were compared between the two groups ( F values were 3.62-66.38, all P<0.05). Conclusions:Slope adjustment mattresses can maintain effective posture, improve comfort, shorten PICU hospital stay and mechanical ventilation time, significantly reduce posture decline and the risk of unplanned tube withdrawal adverse events in PICU mechanically ventilated children. Improving ventilation and ventilation disorders to enhance blood gas analysis indicators.This appliance can be used as an optimized choice for posture management and expected to effectively improve the quality of nursing care.

Objective To analyze the characteristics of conventional ultrasound and contrast-enhanced ultrasound(CEUS)in hypovascular renal tumors,and to explore the application value of combining the 2 methods in diagnosing benign and malignant hypovascular renal tumors.Methods The conventional ultrasound and CEUS data of 104 hypovascular renal tumors(76 benign lesions[benign group]and 28 malignant lesions[malignant group])from 99 patients,who were confirmed by postoperative pathology,biopsy pathology or computed tomography(CT)/magnetic resonance imaging(MRI)enhancement combined with long-term follow-up in Ruijin Hospital,Shanghai Jiao Tong University School of Medicine and its Wuxi Branch from Oct.13,2009 to Oct.26,2022,were retrospectively analyzed.The location,size,internal echo,morphology,internal and peripheral blood supply of the lesions were observed by conventional ultrasound,and the perfusion mode,regression pattern,perfusion uniformity and ring enhancement signs were observed by CEUS.Taking the pathological results or confirmed results of CT/MRI enhancement combined with long-term follow-up as the gold standard,the value of conventional ultrasound combined with CEUS in the differential diagnosis of benign and malignant hypovascular renal tumors was analyzed.Results There were significant differences in gender,age of patients and internal echo,contrast agent regression and ring enhancement signs of lesions between the 2 groups(all P＜0.05).The malignant tumors were mostly found in males(78.6％,22/28)with an average age of(58.29±11.76)years old;the masses were mostly hypoechoic(64.3％,18/28),and rapid washout was predominant with CEUS(60.7％,17/28).In the benign group,most of the patients were female(55.3％,42/76),with an average age of(50.64±14.88)years old;the majority of the masses were hyperechoic(64.5％,49/76),and CEUS showed simultaneous washout as the main lesion(56.6％,43/76).Three patients(10.7％,3/28)with ring enhancement signs were all malignant.The diagnostic accuracy(82.7％)and specificity(88.2％)for benign and malignant hypovascular renal tumors were relatively high when combining the diagnostic indicators of ring enhancement signs and hypoechoic.The diagnostic sensitivity(85.7％)and negative predictive value(92.3％)were relatively high when combining the 3 diagnostic indicators of ring enhancement,hypoechoic,and rapid washout.Conclusion Conventional ultrasound combined with CEUS has significant clinical practical value in the differential diagnosis of benign and malignant hypovascular renal tumors.The ring enhancement sign is highly specific in the diagnosis of malignant hypovascular renal tumors.However,if this sign is not significant and conventional ultrasound shows hypoechoic or CEUS exhibits rapid washout,there is a strong suggestion that the mass may be a malignant lesion.
