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 investigate the correlation between serum microRNA (miR)-15a-5p and prognosis, neoadjuvant chemotherapy (NAC) response in patients with locally advanced gastric cancer (LAGC).Methods:The clinical data of 122 patients with LAGC who underwent surgery after NAC in Eastern Theater Air Force Hospital of the Chinese People′s Liberation Army from May 2016 to April 2020 were analyzed retrospectively. The general clinical data and laboratory examination results of the patients were recorded. The expression level of serum miR-15a-5p was detected by real-time fluorescence quantitative polymerase chain reaction, and the relationship between the expression of miR-15a-5p and different clinical characteristics in patients with LAGC was analyzed. The pathological response was evaluated by Becker tumor regression grading, in which patients with grade 1a, 1b and 2 were sensitive group and patients with grade 3 were resistant group.Results:The patients with LAGC were divided into high expression (>1.038) and low expression (≤1.038) according to the median miR-15a-5p of 1.038 with 61 cases each. The expression level of serum miR-15a-5p was related to the preference for spicy food, endoscopic ultrasonography (EUS)-T stage and EUS-N stage ( P<0.01 or <0.05). According to the evaluation result of pathological reaction, there were 47 cases in resistance group and 74 cases in sensitive group. The serum miR-15a-5p in resistance group was significantly higher than that in sensitive group: 1.69 (1.39, 1.97) vs. 0.99 (0.96, 1.02), and there was statistical difference ( Z =-8.55, P<0.01). The receiver operating characteristic curve analysis result showed that the area under the curve of serum miR-15a-5p predicting NAC response was 0.959 (95% CI 0.929 to 0.990), the optimal cut-off value was 1.049, the sensitivity was 100.0%, and the specificity was 85.1%. Multivariate Logistic regression analysis result showed that miR-15a-5p was an independent risk factor for NAC response in patients with LAGC ( HR = 1 880.840, 95% CI 123.510 to 28 641.846, P<0.01). Kaplan-Meier survival curve analysis result showed that the median overall survival time and median progression free survival time in patients with high expression of miR-15a-5p were significantly shorter than those in patients with low expression of miR-15a-5p (19 months vs. 62 months and 12 months vs. 51 months), and there were statistical differences (log-rank χ2 = 41.99 and 61.97, P<0.01); the 10-year overall survival rate and 10-year progression free survival rate in patients with high expression of miR-15a-5p were significantly lower than those in patients with low expression of miR-15a-5p (4.9% vs. 52.5% and 24.6% vs. 85.2%), and there were statistical differences (log-rank χ2 = 33.70 and 45.32, P<0.01). Multivariate Cox regression analysis result showed that R 0 resection and miR-15a-5p were the independent risk factors affecting the overall survival time and progression free survival time in patients with LAGC (overall survival time: HR = 1.945 and 3.487, 95% CI 1.033 to 3.660 and 2.112 to 5.759, P<0.05 or <0.01; progression free survival time: HR = 2.427 and 6.335, 95% CI 1.069 to 5.510 and 3.341 to 12.013, P<0.05 or <0.01). Conclusions:The increase of serum miR-15a-5p level is related to NAC response and poor prognosis in patients with LAGC. It can be used as a reliable biomarker to predict the prognosis and NAC response of LAGC.

Objective To investigate the effects of glycyrrhizin on the cell model of alcoholic fatty liver(AFL) induced in vitro and its possible mechanism.Methods The in vitro induced AFL cells were divided into the control group,separating ethanol group,glycyrrhizin group and continuous induction group.The levels of intracellular triglyceride(TG) and leakage amounts of ALT and AST,cell cycle change and protein and mRNA expressions of PPAR-γ,SREBP-1 and SCAP were measured.Results Glycyrrhizin could obviously reduce the apoptosis occurrence;compared with the control group,the level of intracellular TG and the leakage amounts of ALT and AST,and the protein and mRNA expressions of PPAR-γ,SREBP-1 and SCAP were significantly decreased(P＜0.05).Conclusion Glycyrrhizin may alleviate the fat change of in vitro induced AFL cells by down-regulating expressions of PPAR-γ,SREBP-1 and SCAP.

Objective To investigate the protective mechanism of MEK1/2 inhibitor PD98059 on ox-LDL induced injury of human umbilical vein endothelial cells (HUVEC),and its influence on the expression of LOX-1.Methods HUVEC damage models were established by using ox-LDL and were treated with PD98059 later,divided into the negative control group,the ox-LDL group,the positive control group and the PD98059+ox-LDL group.The effect of inhibition of MEK1/2 on ox-LDL induced HUVEC damage was measured.Results Compared with the negative control group,the levels in the ox-LDL group of LOX-1,pMEK1/2,RhoA,ROCK1,ROCK2,TNF-α and IL-6 were increased significantly,the proliferations of HUVEC and the productions of NO were decreased (P＜0.05).Compared with the ox-LDL group,the levels in the positive control group and the PD98059+ox-LDL group of pMEK1/2,RhoA,ROCK1,ROCK2,TNF-α and IL-6 were decreased,the proliferation of HUVEC and the production of NO were increased (P＜0.05).Conclusion PD98059 inhibit the MEK1/2 signaling pathway to suppress the ox-LDL induced damage of HUVEC by decreasing the expression of LOX-1.

Objective To observe the usage of antiasthmatic drugs and seek problems of following the guidelines of asthma and COPD prevention & treatment in community hospitals.Methods The prescribed quantity in 2013 of antiasthmatic drugs was recorded for 5 community hospitals in a district of Shanghai.Basing on the defined daily dose (DDD),the dosing frequency of drugs (DDDs) and the percentages of each category of drugs were calculated.Then comparisons were made with the data of a grade Ⅱ hospital and a grade Ⅲ hospital in the same district.Results Among three level hospitals,no significant difference existed in the percentages of oral antiasthmatic drugs.But the major category of oral drugs at grades Ⅱ-Ⅲ hospitals was leukotriene receptor antagonist whereas only oral theophylline and oral β2-receptor agonists were available at community hospitals.Among inhaled drugs,inhaled corticosteroids (ICS) dominated at grades Ⅱ-Ⅲ hospitals.But at community hospitals,inhaled short-acting beta-agonists (SABA) predominated.Among inhalants,dry powder inhaler (DPI) dominated at grades Ⅱ-Ⅲ hospitals and metered dose inhaler (MDI) at community hospitals.Conclusions The usage of antiasthmatics at community hospitals is not consistent with the guidelines.Optimizing drug purchasing at hospitals,strengthening continued medical education,modifying the medication concept of patients and boosting the production of domestic inhalants should be urgently undertaken.
