OBJECTIVE To clarify the current development status of clinical pharmacist training bases and the pharmacist workforce in China， and to provide evidence for standardizing base construction and promoting the high-quality development of hospital pharmacy. METHODS Questionnaires were distributed to all clinical pharmacist training bases for urgently-needed health professionals and clinical pharmacist training bases under the Chinese Hospital Association that had been approved by the end of 2023 to collect data including base profiles and pharmacist staffing conditions. Expert teams carried out field investigations to verify the collected data. Descriptive statistical analyses were conducted on the quantity， type and regional distribution of training bases， and the influencing factors of pharmacist staffing in the bases were analyzed. RESULTS Field surveys were completed covering 297 training bases across 31 provincial-level administrative regions. Among the base hospitals， 87.88% were Grade A tertiary general hospitals， and 65.32% were located in provincial capitals. The eastern region had the largest number of bases （136， accounting for 45.79%）， followed by the western region （79， 26.60%）. Great disparities existed among provinces in terms of base quantity and hospital scale. The median proportion of pharmaceutical technical personnel in base hospitals was 4.05%， and the median number of clinical pharmacists per 100 hospital beds was 0.53. Both indicators reached the highest in the eastern region （0.57， 4.43%） and the lowest in the northeastern region （0.45， 3.01%）. A total of 3 627 full-time clinical pharmacists were employed in all surveyed bases， among whom 83.68% held clinical pharmacist training certificates， 35.43% possessed senior professional titles， and 78.19% had postgraduate or higher educational background. The total annual training capacity of the surveyed bases was 4 291 trainees， with obvious differences in annual training capacity across regions and provinces. Training specialties covered 19 specialized disciplines plus one general discipline， and no province could deliver training for all 20 specialties simultaneously. Multivariate Logistic regression analysis showed that geographic region exerte d a significant impact on the proportion of pharmaceutical technical personnel （≥4%） （ P ＜0.05）， while the approval time of training bases and hospital scale had significant effects on the number of clinical pharmacists per 100 beds （≥0.6） （ P ＜0.05）. CONCLUSIONS China’s clinical pharmacist training system has basically matured and taken initial shape. The distribution of clinical pharmacist training resources is generally consistent with regional population and economic development levels. However， the allocation of pharmaceutical staff and clinical pharmacists has not yet met national standards and clinical service demands.

OBJECTIVE To investigate the current status of quality management in clinical pharmacist training bases in China， and to provide references for the standardized development and improvement of these bases. METHODS A combined approach of questionnaire survey and on-site investigation was adopted， targeting the healthcare highly sought-after talent （clinical pharmacist） training bases in 31 provinces of China as well as the clinical pharmacist training bases affiliated with the Chinese Hospital Association. A training quality management evaluation index system consisting of 25 tertiary indicators was established. Investigations were conducted from two dimensions： structural quality of training and quality management of training processes. Data were statistically analyzed using descriptive statistical methods. RESULTS On-site investigations were completed for 297 clinical pharmacist training bases across the 31 provinces， among which 284 were affiliated with the Chinese Hospital Association and 271 were healthcare highly sought-after talent （clinical pharmacist） training bases. In terms of structural quality， the core indicator compliance rate for hospital-level training systems exceeded 80%， the rate of special fund utilization for designated purposes reached 80.13%， and the overall compliance rate for software and hardware facilities surpassed 88%. A total of 1 348 preceptors were employed across the training bases， among whom those with senior professional titles and full-time specialist clinical pharmacists as lead preceptors accounted for 62.91% and 94.36%， respectively. Regarding process quality， the compliance rate for “establishment of clinical practice teaching groups in accordance with regulations during clinical department rotations” was 85.19%， and 79.80% and 76.09% of the bases were found to implement strict confidentiality in theoretical examinations and meet the required scale of assessment cases， respectively. However， formal documents of corresponding training management regulations were formulated in only 57.91% of the bases， and the completeness and standardization rate of training manual completion was merely 47.47%. In addition， considerable disparities in quality management levels were observed among provinces， with issues in training process quality being particularly prominent. CONCLUSIONS The management system， hardware facilities， and preceptor staffing of clinical pharmacist training bases in China are relatively well-established， yet notable variations in quality management exist among training bases across different provinces.

Objective:To explore the correlation between intestinal flora disturbance and the diagnosis,treatment of rheumatoid arthritis(RA),and to provide bioinformatics basis for further research on precise targeted intervention of RA.Methods:Genes related to intestinal flora disorders and RA genes were downloaded from disease database.Correlation between the two diseases was analyzed via bioinformatics approach.PPI network was conducted by STRING,Cytoscape and their plug-ins,and key genes were screened.Key genes were mapped into Coremine Medicinal to identify medicinal chemicals and medicinal herbs.Results:A total of 525 genes shared by intestinal flora disorders and RA were obtained through integrated screening of the disease database,and key genes with the highest degree of protein interaction were finally selected,namely IL-6,IL-1β,TNF-α,IL-10,STAT3,STAT1 and RELA.These related tar-geted genes were mainly involved in biological processes such as negative feedback regulation and antigen stimulation,and mediate molecular functions such as lipopolysaccharide receptor binding and NF-κB receptor binding,which are mainly concentrated in the plasma membrane region.KEGG analysis showed that these related genes were mainly involved in classical signaling pathways such as IL-17 pathway and Toll-like receptor pathway.Through drug prediction,it was found that Astragalus,Scutellaria,Schisandra and Cop-tis in traditional Chinese medicine might be potential drug sources for RA treatment.Conclusion:Bioinformatics method can predict key genes and signaling pathways of intestinal flora intervention in pathogenesis and progression of RA,and predict the Chinese herbs that may target the regulation of flora for treatment of risk factors,which providing a theoretical basis for further exploration of targeted treatment of RA.

BACKGROUND:Exosomes derived from human umbilical cord mesenchymal stem cells are widely used for bone repair and reconstruction,significantly enhancing osteogenesis and promoting angiogenesis.OBJECTIVE:To explore the mechanisms of exosomes derived from human umbilical cord mesenchymal stem cells in the treatment of osteoporotic fractures.METHODS:H uman umbilical cord mesenchymal stem cells were extracted using tissue block culture method.Exosomes derived from human umbilical cord mesenchymal stem cells were extracted using ultracentrifugation method for identification.Thirty 12-week-old female SD rats were randomly divided into sham-operated group(n=6)and ovariectomized group(n=24).Osteoporosis model was established by castration in the ovariectomized group.12 weeks after modeling,6 rats in the ovariectomized group and 6 rats in the sham-operated group were randomly selected for Micro-CT and hematoxylin-eosin staining to verify the models.After verification,the remaining 18 rats in the ovariectomized group were randomly assigned to three groups to establish osteoporotic fracture models.The fracture end was separately injected with PBS(PBS group),exosomes at 1.5×1011 particles/mL(low-concentration exosome group),and 3×1011 particles/mL(high-concentration exosome group).Four weeks after operation,fracture healing and bone angiogenesis were evaluated by imaging and histological observations.RESULTS AND CONCLUSION:(1)In the gross specimens,compared with the PBS group,the exosome group had faster fracture healing and more callus formation.(2)The X-ray score of fracture healing in the exosome group was significantly higher than that in the PBS group,and the difference was significant(P＜0.05).(3)Micro-CT three-dimensional imaging:Compared with the PBS group,the fracture healing in the exosome group was accelerated and the callus formation was significantly increased;the bone volume fraction in the exosome group was significantly higher than that in the PBS group,and the difference was significant(P＜0.01).(4)Hematoxylin-eosin staining and Masson's trichrome staining showed that bone trabeculae and the new bone tissue in the exosome group were more than those in the PBS group.(5)Immunohistochemical staining showed that the expression of CD31 and osteocalcin in the exosome group was significantly higher than that in the PBS group.The high-concentration exosome group had a higher density of new blood vessels,more callus formation,and faster fracture healing than the low-concentration exosome group,showing a concentration-dependent manner.The results show that exosomes derived from human umbilical cord mesenchymal stem cells can promote the repair of osteoporotic fracture by enhancing the angiogenesis and osteogenesis.The mechanism may be related to the increased expression of CD31 and osteocalcin.

Objective To observe the dynamic changes of molecules related to the Nrf2/Keap1/p62 signaling pathway in patients with postoperative pulmonary inflammation after thoracic surgery,and explore its relationship with prognosis.Methods Sixty patients with postoperative pneumonia after thoracic surgery who met the criteria in the Department of Thoracic Surgery of Taihe County Hospital of Traditional Chinese Medicine from June 2023 to June 2024 were selected as the research subjects.Venous blood was collected from the pa-tients on the day before surgery,the first day after surgery,the third day after surgery,and the seventh day after surgery to detect the lev-els of superoxide dismutase(SOD),nitric oxide(NO),malondialdehyde(MDA),reactive oxygen species(ROS)in peripheral blood,as well as the expression of Nrf2,Keap1,and p62 mRNA.The correlations between these indicators and the prognosis of postoperative pulmonary infection after thoracic surgery were analyzed.Results The SOD level of the patients decreased after the operation compared with that before the operation,reaching the lowest value on the first day after the operation.The levels of MDA and ROS increased after the operation,but slowly decreased on the seventh day after the operation.There was no significant change in the NO level compared with that before the operation.Compared with before the operation,the expression levels of Nrf2 and Keap1 in the patients decreased signifi-cantly on the first day after the operation,and then slowly increased.The expression level of p62 increased to the peak on the first day af-ter the operation,and then decreased.The results of lung function index measurement showed that the patients had pulmonary infection af-ter the operation,and the lung function level decreased significantly compared with that before the operation.Through ROC curve analy-sis,the dynamic changes of SOD,ROS,Nrf2,Keap1 and p62 in the patients with pulmonary inflammation after thoracic surgery have good predictive value for prognosis.Conclusion The changes of Nrf2/Keap1/p62 signaling pathway-related factors in patients with post-thoracic surgery-induced pulmonary inflammation are significantly correlated with the prognosis of these patients.Such changes can effectively predict the prognosis of patients from the perspective of the expression levels of related genes.

Objective To understand the equity and influencing factors of maternal health service utilization in Changning District, Shanghai. Methods A convenience sampling method was used to conduct a questionnaire survey among mothers of children aged 1 to 1.5 years old who received health services from the child health care clinics and EPI clinics of 10 community health service centers in Changning District, Shanghai from March to April 2022. Count data was expressed by frequency and percentage. Chi-square analysis, binomial logistic regression analysis, and multivariate logistic regression analysis were used to analyze fairness-related factors. Rate difference, rate ratio and concentration index were used to represent fairness. Results A total of 696 subjects were investigated, with an average age of (33.35±4.76) years. There were statistically significant differences in service utilization among women with different household registrations only in early pregnancy registration (χ²=11.026, P=0.001) and postpartum visits (χ²=4.989, P=0.026). Women with a career showed differently in folic acid supplement (χ²=6.247, P=0.012), early pregnancy registration (χ²=12.989, P=0.002), physical examination in 42 days postpartum (χ²=4.446, P=0.035) and postpartum contraception (χ²=4.061, P=0.044), and the differences were statistically significant. Women with different monthly family income had a statistically significant difference in pre-pregnancy examination (χ²=8.977, P=0.030) and postpartum visit (χ²=16.114, P=0.001). There was a statistically significant difference between women with maternity insurance or not in the early pregnancy registration (χ²=10.576, P=0.001) and physical examination in 42 days postpartum (χ²=8.166, P=0.004). The results of the multivariate analysis showed that occupation (OR=2.616, 95% CI: 1.142-5.990) and maternity insurance (OR=4.490, 95% CI: 1.992~10.120) affected the utilization of service in early pregnancy registration. The monthly household income (OR=0.278, 95% CI: 0.124-0.625) affected the utilization of services in postpartum visit. At the same time, the monthly household income (10,000-19,999: OR=0.286, 95% CI: 0.090-0.907; ≥30,000: OR=0.180, 95% CI: 0.041-0.801) also affected the utilization of service in physical examination in 42 days postpartum. Conclusion The equity of maternal health care service utilization overall is good in central area in Shanghai, but there is still room for improvement. It is necessary to strengthen community mobilization, propagandize maternal health services, and expand the coverage of maternity insurance to improve the equity of maternal health service utilization and provide equal access to maternity health services.
