Objective: To analyze the serological and molecular biological characteristics of one case with Ael subtype. Methods: ABO serological typing was performed using the tube method. ABO genotyping was conducted by sequence-specific primer polymerase chain reaction (PCR-SSP). The genotype was identified by Oxford Nanopore third-generation sequencing (TGS). Pymol, Polyphen-2, PROVEAN, and DUET were used to predict the effects of mutations on protein structure and function. Results: Serological testing identified an Ael subtype. PCR-SSP genotyping showed an A/O2 profile. TGS obtained two full-length ABO haplotype sequences: the first was ABO
O.01.02, and the second was a recombinant haplotype of ABO
B.01-O.01.02, with the recombination breakpoint mapped between c. 357-39 and c. 526G>C. Mutations on this recombinant allele included c. 297A>G, c. 646T>A, c. 681G>A, c. 771C>T, and c. 829G>A, among which c. 646T>A (p. Phe216Ile) and c. 829G>A (p. Val277Met) were two functional amino acid substitution sites. Protein structure modeling revealed alterations in local conformation and hydrogen bond network, and functional prediction indicated decreased protein stability. Conclusion: A recombination between ABO alleles B.01 and O.01.02 was identified in the region spanning intron 6 to exon 7, resulting in a B.01-O.01.02 recombinant gene. This recombinant leads to key amino acid substitutions in the B glycosyltransferase, causing local structural changes and decreased stability of the enzyme protein, ultimately manifesting as the Ael blood group phenotype.

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.

The analysis presented here is based on the blood components of Guanxin Qiwei tablets, the key anti-atherosclerosis pathway of Guanxin Qiwei tablets was screened by network pharmacology, and the anti-atherosclerosis mechanism of Guanxin Qiwei tablets was clarified and verified by cell experiments. HPLC-Q-Exactive-MS/MS technique was used to analyze the components of Guanxin Qiwei tablets into blood, to determine the precise mass charge ratio of the compounds, and to conduct a comprehensive analysis of the components by using secondary mass spectrometry fragments and literature comparison. Finally, a total of 42 components of Guanxin Qiwei tablets into blood were identified. To better understand the interactions, we employed the Swiss Target Prediction database to predict the associated targets. Atherosclerosis (AS) disease targets were searched in disease databases Genecard, OMIM and Disgent, and 181 intersection targets of disease targets and component targets were obtained by Venny 2.1.0 software. Protein interactions were analyzed by String database. The 32 core targets were selected by Cytscape software. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed in DAVID database. It was found that the anti-atherosclerosis pathways of Guanxin Qiwei tablets mainly include lipid metabolism and atherosclerosis and AGE-RAGE signaling pathway in diabetic complications and other signal pathways. The core targets and the core compounds were interlinked, and it was found that cryptotanshinone and tanshinone ⅡA in Guanxin Qiwei tablets were well bound to TNF, PPAR

Lean six sigma (LSS) emphasizes patient demand-oriented, and continuously optimizing prolesses to achieve efficiency and standardization in medical services. Starting in 2021, a specialized children′s hospital (comprising one main campus and three branch campuses) introduced the LSS management method. Through define, measure, analyze, improve, and control, the hospital utilized tools such as questionnaire surveys, SIPOC models, and fishbone diagrams to identify pain points in the building of multi-campus child-friendly hospital and develop improvement measures.To address the main issues of insufficient cross-campus collaboration, significant disparities in service quality among different campuses, unclear functional positioning of each campus, and inadequate integration with social security mechanisms, the hospital implemented a " homogeneity-differentiation-coordination" management mode. The hospital implemented unified diagnosis and treatment standards and clinical pathways, carried out remote consultations and expert rotations, completed mutual recognition of examination and testing results, optimized child friendly labeling and child friendly environment, and built a " hospital-to-hospitals, hospital to medical schools, and hospital to community health centers" linkage platform, etc., to promote the standardization of diagnosis and treatment processes, clear functional positioning of the hospital area, and efficient resource allocation. Through practice, the outpatient appointment rate and patient satisfaction rate in the main hospital had increased from 86.72% and 98.64% in January December 2021 to 91.87% and 99.72% in January December 2024, respectively; The patient waiting time had been shortened from 26.54 minutes to 21.94 minutes, and the efficiency of medical treatment and service experience had been significantly improved. As of 2024, mutual recognition of 214 inspection and testing items had been achieved cross hospital campuses, forming a collaborative pattern of " main hospital leading, campuses support, and resource complementarity", and significantly improving the level of collaboration and child friendly connotation among multi-campus. This practice explored the integration path of multi-campus collaborative governance and child-friendly services, which could provide reference and inspiration for the similar hospitals.

Objective:To investigate the clinical, pathological, and molecular biological characteristics of gastric hepatoid adenocarcinoma (HAS) in order to provide reference for clinical treatment.Methods:Thirty-two patients diagnosed with hepatoid adenocarcinoma after radical gastrectomy for gastric cancer at Shanxi Cancer Hospital were included from January 2019 to December 2021. Immunohistochemistry, in situ hybridization, and next-generation sequencing (NGS) methods were used to analyze immune markers and molecular characteristics in the pathological tissues from 32 patients with HAS. Cox regression analysis and Kaplan-Meier method were used to analyze the prognostic factors of overall survival and disease-free survival.Results:Among the 32 patients with HAS, 26 were male, 6 were female; aged 28-77 years, with an median age 62.0 (53.8, 67.2) years. Fifteen cases of HAS were located in the cardia, 10 cases in the antrum, and 7 cases in the body of the stomach. The maximum diameter of the mass was 3-10 cm, and mainly ulcerative in gross. The immunohistochemistry and in situ hybridization results showed that the positive rates of AFP, SALLA4, and Glypican-3 were 68.8% (22/32), 68.8% (22/32), 78.1% (25/32), respectively; Seven patients had microsatellite status of dMMR. Two cases of HER2 gene amplification and 2 cases of EB virus positivity. The NGS results showed that HAS was often accompanied by multiple gene mutations, with 23 cases having ≥ 2 gene mutations and 6 cases having ≥10 gene mutations. The TP53 gene had the highest mutation frequency; 4 cases had genetic structural variations; 28 cases had copy number variation. In addition, there were 7 cases of MSI-H and 9 cases of TMB-H. Follow-up results showed that 12 cases died, 9 cases developed metastasis, and the shortest survival time was 5 months.Conclusions:Gastric HAS is a type of tumor with high invasiveness and poor prognosis. The combined detection of AFP, SALLA4 and Glypican-3 can improve the diagnostic rate of tumors. dMMR/MSI-H and TMB-H patients in HAS are significantly higher than those in ordinary gastric cancer, and the high frequency mutation genes in HAS are often accompanied by multiple potential therapeutic targets. Immunotherapy combined with chemotherapy and targeted therapy are expected to become the treatment direction of HAS.

BACKGROUND:
Spatiotemporal disparities exist in the disease burden of non-communicable diseases (NCDs) attributable to kidney dysfunction, which has been poorly assessed. The present study aimed to evaluate the spatiotemporal trends of the global burden of NCDs attributable to kidney dysfunction and to predict future trends.
METHODS:
Data on NCDs attributable to kidney dysfunction, quantified using deaths and disability-adjusted life-years (DALYs), were extracted from the Global Burden of Diseases Injuries, and Risk Factors (GBD) Study in 2019. Estimated annual percentage change (EAPC) of age-standardized rate (ASR) was calculated with linear regression to assess the changing trend. Pearson's correlation analysis was used to determine the association between ASR and sociodemographic index (SDI) for 21 GBD regions. A Bayesian age-period-cohort (BAPC) model was used to predict future trends up to 2040.
RESULTS:
Between 1990 and 2019, the absolute number of deaths and DALYs from NCDs attributable to kidney dysfunction increased globally. The death cases increased from 1,571,720 (95% uncertainty interval [UI]: 1,344,420-1,805,598) in 1990 to 3,161,552 (95% UI: 2,723,363-3,623,814) in 2019 for both sexes combined. Both the ASR of death and DALYs increased in Andean Latin America, the Caribbean, Central Latin America, Southeast Asia, Oceania, and Southern Sub-Saharan Africa. In contrast, the age-standardized metrics decreased in the high-income Asia Pacific region. The relationship between SDI and ASR of death and DALYs was negatively correlated. The BAPC model indicated that there would be approximately 5,806,780 death cases and 119,013,659 DALY cases in 2040 that could be attributed to kidney dysfunction. Age-standardized death of cardiovascular diseases (CVDs) and CKD attributable to kidney dysfunction were predicted to decrease and increase from 2020 to 2040, respectively.
CONCLUSION
NCDs attributable to kidney dysfunction remain a major public health concern worldwide. Efforts are required to attenuate the death and disability burden, particularly in low and low-to-middle SDI regions.

A scoping review was performed to systematically search and summarize the clinical research in the treatment of dysmenorrhea with oral Chinese patent medicines. The oral Chinese patent medicines for treating dysmenorrhea in three major drug lists, guidelines, and textbooks were screened, and the relevant clinical trials were retrieved from eight Chinese and English databases. The key information of the included trials was extracted and visually analyzed. A total of 50 Chinese patent medicines were included, among which oral Chinese patent medicines for the dysmenorrhea patients with the syndrome of Qi stagnation and blood stasis accounted for the highest proportion, and the average daily cost varied greatly among Chinese patent medicines. A total of 150 articles were included, involving 22 Chinese patent medicines, among which Guizhi Fuling Capsules/Pills, Sanjie Zhentong Capsules, and Dan'e Fukang Soft Extract were the most frequently studied. These articles mainly reported randomized controlled trial(RCT), which mainly focused on the comparison of the intervention effect between Chinese patent medicines combined with western medicine and western medicine alone, and the sample size was generally 51-100 cases. The high-frequency outcome indicators belonged to nine domains such as effective rate, adverse reactions, and laboratory examinations. This study showed that oral Chinese patent medicines had advantages in the treatment of dysmenorrhea, and the annual number of related clinical trials showed an overall growing trend. However, there were still problems such as insufficient safety information and vague description of traditional Chinese medicine(TCM) syndromes types in the instructions of Chinese patent medicines. The available clinical research had shortcomings such as uneven distribution of Chinese patent medicines, limited research scale, poor methodological rigor, and insufficient standardization of outcome indicators. In the future, it is necessary to deepen the development of high-quality clinical research and improve the contents of the instructions to ensure the effectiveness and safety of the clinical application of oral Chinese patent medicines in the treatment of dysmenorrhea.
