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 analyze the status of willingness to participate in health science popularization (HSP) and its influencing factors among medical workers in Guangdong Province. Methods A total of 462 medical workers in Guangdong Province were recruited as the study subjects using a stratified convenience sampling method. The Questionnaire on Influencing Factors of Willingness to Participate in Health Science Popularization, developed by the research team, was used to investigate their willingness to participate in HSP and related variables, including previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support. Hierarchical regression analysis was used to identify the influencing factors of willingness to participate in HSP. Results The median and 25^th and 75^th percentiles score of willingness to participate in HSP was 4.0 (3.8, 4.5), indicating a moderately high level of willingness. The HSP participation willingness score was positively correlated with scores for previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support (Spearman correlation coefficients were 0.513, 0.384, 0.507, 0.533, 0.463, 0.556, and 0.435, respectively; all P<0.01). Hierarchical regression analysis showed that previous communication experience, moral belief, descriptive norm and self-efficacy positively predicted willingness to participate in HSP (all P<0.05). Medical workers in the non-Pearl River Delta region had lower willingness than those in the Pearl River Delta region for HSP participation (P<0.05). Conclusion There is still room for improving willingness for HSP participation among healthcare professionals in Guangdong Province. It is recommended to enhance self-efficacy through communication skills training, strengthen professional ethics education, foster a positive peer engagement atmosphere, and intensify resource support and capacity building for HSP in the non-Pearl River Delta region, to improve HSP participation willingness among medical workers in Guangdong Province.

Objectives:To investigate the association between cardiac magnetic resonance(CMR)structural parameters and myocardial fibrosis in patients with hypertrophic cardiomyopathy(HCM),and to assess their predictive value for major adverse cardiovascular events(MACE).Methods:A total of 120 patients with HCM who underwent CMR examination at Affiliated Hospital of Guangdong Medical University between December 2021 and December 2023 were retrospectively enrolled.Patients were divided into the MACE group and the non-MACE group.MACE included acute myocardial infarction,angina pectoris,stroke,heart failure,severe arrhythmia.The CMR parameters were compared between the two groups.The correlation between CMR structural parameters and the myocardial fibrosis index(number of myocardial fibrotic segments/total segment number×100%)was evaluated using the locally weighted scatterplot smoothing method(LOWESS).Multivariate Cox regression was performed to identify the influencing factors of MACE.Threshold effect analysis of CMR structural parameters was conducted,and receiver operating characteristic(ROC)curves were generated to evaluate the diagnostic performance of CMR structural parameters for MACE.Results:During a follow-up period of 12(5,30)months,a total of 78(65.0%)patients developed MACE(the MACE group),and the remaining 42(35.0%)patients were assigned to the non-MACE group.Compared with the non-MACE group,patients in the MACE group had significantly larger left atrial diameter,left ventricular end-diastolic maximum diameter,maximal interventricular septal thickness,maximal left ventricular wall thickness,and higher myocardial fibrosis index(all P<0.05).The LOWESS analysis showed significant positive correlations between the above CMR structural parameters and the myocardial fibrosis index(all Poverall<0.05).The multivariate Cox regression showed that the echocardiographic interventricular septal thickness OR=2.622,95%CI:1.537-3.033),left ventricular posterior wall thickness(OR=1.597,95%CI:1.353-2.420),as well as CMR-derived left atrial diameter(OR=1.623,95%CI:1.314-2.595),left ventricular end-diastolic maximum diameter(OR=1.927,95%CI:1.594-2.981),maximal interventricular septal thickness(OR=2.085,95%CI:1.426-2.563),and maximal left ventricular wall thickness(OR=2.306,95%CI:1.760-2.805)were independent predictors of MACE(all P<0.05).The threshold effect analysis revealed that the left atrial diameter,left ventricular end-diastolic maximum diameter,maximal interventricular septal thickness,and maximal left ventricular wall thickness were all positively associated with the risk of MACE(all Poverall<0.05).The ROC curve analysis demonstrated that among individual CMR parameters,maximal interventricular septal thickness had the highest predictive performance(AUC=0.86,95%CI:0.74-0.95;sensitivity was 83.67%,specificity was 78.87%).Combined structural parameters(left atrial diameter,left ventricular end-diastolic maximum diameter,maximal interventricular septal thickness,and maximal left ventricular wall thickness)provided superior predictive accuracy(AUC=0.91,95%CI:0.84-0.99;sensitivity was 86.22%,specificity was 76.26%).Conclusions:HCM patients with MACE exhibit distinct clinical and imaging features compared with those without MACE.CMR structural parameters,including left atrial diameter,left ventricular end-diastolic maximum diameter,maximal interventricular septal thickness,and maximal left ventricular wall thickness,are closely related to myocardial fibrosis and strongly associated with MACE risk.A composite index integrating these parameters shows high predictive value for MACE.

Objective:To assess the impacts of abdominal spectral computed tomography (CT) scans on radiation dose in order to validate the feasibility of low-dose spectral CT imaging.Methods:Using varying scanning protocols on the Discovery CT750 HD device, the abdomen of an adult male dose-specific phantom was scanned in two modes: conventional single-energy CT (SECT) and gemstone spectral imaging (GSI). Specifically, the conventional SECT mode featured tube voltages of 120 and 80 kVp, automatic tube current modulation technology, and a noise index (NI) of 10 HU. In contrast, the GSI mode was characterized by the automatic spectral imaging protocol selection (ASIS) technique, rapid switching of the tube voltage between 80 and 140 kVp, and Nis for non-spectral scanning of 8, 10, 15, and 20 HU. Then, various radiation dose metrics and objective image quality were compared across different scanning protocols.Results:In the case of the same NI, the three scanning dose modes (SECT with tube voltages of 120 and 80 kVp, and GSI with a tube voltage of 80/140 kVp) presented similar volume CT dose index (CTDI vol) and dose length product (DLP). However, the SECT with a tube voltage of 80 kVp showed the lowest measured organ absorbed dose ( DT; 5.89 mSv). Effective dose ( E) was determined using DLP and organ DT. The result indicated that, under the three modes except for SECT with a tube voltage of 80 kVp, the E values calculated using DLP were lower than those determinized using the organ DT, with deviations ranging from 9% to 20%. The differences in image noise levels and signal-to-noise ratios (SNR) of the three scanning modes were statistically significant ( F = 65.52, 35.09, P < 0.001). Conclusions:Spectral CT using ASIS technology can achieve low-dose spectral scanning while ensuring image quality.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

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.

This study aimed to establish adult reference intervals for coagulation parameters using the CN-6000 fully automated coagulation analyzer. It also compared the applicability of direct and indirect methods in different populations. A cross-sectional and retrospective design was employed. The direct method included patients from the colorectal surgery and dermatology departments, as well as healthy participants from phase I clinical trials, admitted to the West Campus of China-Japan Friendship Hospital from April to December 2023. Participants were divided into two age groups: younger adults (18-64 years) and older adults (≥65 years). Coagulation parameters were tested, and reference intervals were determined. The indirect method applied the refineR algorithm to analyze coagulation data from non-ICU patients during the same period. The performance of both methods was evaluated in healthy participants, relatively healthy patients, and patients with high disease prevalence. The results showed that the direct method yielded similar reference intervals for APTT, PT, and TT in younger and older groups, with combined intervals of 23.7-31.2 seconds, 10.4-12.8 seconds, and 14.7-17.5 seconds, respectively. However, the Fib showed a significant difference between the two groups ( U=1 052 023, P<0.01), and separate reference intervals were established: 1.7-4.5 g/L for the younger group and 2.1-4.6 g/L for the older group. The reference intervals derived by the indirect method are similar to those from the direct method: APTT 23.8-31.4 seconds, PT 10.4-13.0 seconds, TT 14.5-17.4 seconds, and Fib 1.8-4.3 g/L (18-64 years) and 2.1-4.5 g/L (≥65 years). In relatively healthy patients, the reference intervals obtained by both methods were comparable, but significant differences were observed in patients with high disease prevalence. In conclusion, this study established localized reference intervals for the CN-6000 fully automated coagulation analyzer. The indirect method can serve as an alternative to the direct method in healthy and relatively healthy populations. However, its applicability in populations with high disease prevalence is limited and requires cautious interpretation in the context of clinical settings.
