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 construct the rpoN gene knockout strain (Δ rpoN) and the complemented strain (CΔ rpoN) of Vibrio vulnificus ( V. vulnificus), and investigate the role of the rpoN gene in regulating bacterial motility and biofilm formation. Methods:The Δ rpoN strain of V. vulnificus was constructed using homologous recombination. Bacterial motility was assessed via swimming assays, and flagellar morphology was observed by transmission electron microscopy. Biofilm formation capacity was evaluated using crystal violet and Congo red staining assays, as well as colony morphology analysis. Real-time quantitative RT-PCR (qRT-PCR) was used to detect mRNA levels of target genes associated with flagellar synthesis and biofilm formation in Δ rpoN and the wild-type strains. Results:The V. vulnificus genome harbored a single rpoN gene, encoding a protein with high amino acid sequence similarity to RpoN homologs in other bacterial species. The Δ rpoN strain was successfully constructed. Compared with the wild-type strain, the Δ rpoN strain exhibited complete loss of motility on soft agar plates, absence of flagellar, and downregulated mRNA levels of flagellar synthesis-related genes. Conclusions:In V. vulnificus, RpoN regulates flagellar assembly by modulating the expression of flagellar synthesis genes, thereby controlling bacterial motility and biofilm formation.

Complement C3 plays a critical role in periodontitis. However, its source, role and underlying mechanisms remain unclear. In our study, by analyzing single-cell sequencing data from mouse model of periodontitis, we identified that C3 is primarily derived from periodontal fibroblasts. Subsequently, we demonstrated that C3a has a detrimental effect in ligature-induced periodontitis. C3ar^-/- mice exhibited significantly less destruction of periodontal support tissues compared to wild-type mice, characterized by mild gingival tissue damage and reduced alveolar bone loss. This reduction was associated with decreased production of pro-inflammatory mediators and reduced osteoclast infiltration in the periodontal tissues. Mechanistic studies suggested that C3a could promote macrophage polarization and osteoclast differentiation. Finally, by analyzing single-cell sequencing data from the periodontal tissues of patients with periodontitis, we found that the results observed in mice were consistent with human data. Therefore, our findings clearly demonstrate the destructive role of fibroblast-derived C3 in ligature-induced periodontitis, driven by macrophage M1 polarization and osteoclast differentiation. These data strongly support the feasibility of C3a-targeted interventions for the treatment of human periodontitis.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

Objective:To study the expression of transcription factor 12 (TCF12) in colorectal cancer cells, and to explore the effects of TCF12 on proliferation, migration, and aerobic glycolysis of colorectal cancer HT-29 cells and its mechanism.Methods:After culturing, HT-29 cells were divided into a control group and a knockdown group based on treatment conditions, and were transfected with 50 nmol/L of small interfering RNA (siRNA) and TCF12 siRNA, respectively. On the basis of the knockdown group, HT-29 cells were infected with adenovirus vector overexpressing αB-crystallin (CRYAB) with an infection multiplicity of 50, which was set as the overexpression group. The relative expression of TCF12 in HT-29 cells was detected using Western blotting. The cell survival rate, cell clone number and cell migration number of HT-29 cells were detected using cell counting kit-8, clone formation assay and cell invasion assay, respectively. Glucose uptake, relative lactic acid production and adenosine triphosphate (ATP) level of HT-29 cells were detected by related kits. The relative expression of glucose transporter 1 (GLUT1), hexokinase 2 (HK2), lactate dehydrogenase A (LDHA), CRYAB, phosphorylated phosphoinositide 3-kinase (p-PI3K)/PI3K and phosphorylated protein kinase B (p-Akt)/Akt proteins were detected by Western blotting. Data were analyzed by an independent sample t test or one-way analysis of variance. Results:The relative expression of TCF12 protein in the knockdown group was lower than that in the control group (0.14±0.03 vs 0.99±0.05, t=7.526, P<0.01). The cell survival rate, the cell clone number and the cell migration number per unit field of view in the knockdown group were all lower than those in the control group [(60.00±5.10)% vs (94.67±2.08)%, t=15.368, P<0.01; 52±5 vs 148±6, t=23.164, P<0.01; 26±4 vs 78±4, t=18.265, P<0.01].

The relative expression of GLUT1, HK2 and LDHA proteins in the knockdown group were all lower than those in the control group (0.38±0.05 vs 0.98±0.09, 0.12±0.03 vs 0.97±0.04, and 0.64±0.05 vs 0.99±0.06, all P<0.01). The relative expression of CRYAB, p-PI3K/PI3K and p-Akt/Akt proteins in the knockdown group were all lower than those in the control group (0.18±0.04 vs 0.92±0.03, t=11.265, P<0.01; 0.34±0.10 vs 0.92±0.04, t=18.257, P<0.01; 0.51±0.04 vs 1.11±0.07, t=13.165, P<0.01). The cell survival rate, the cell clone number and the cell migration number per unit field of view p in the overexpression group were all higher than those in the knockdown group [(97.00±6.56)% vs (45.67±6.03)%, t=12.762, P<0.01; 136.67±5.69 vs 44.33±6.03, t=22.585, P<0.01; 57.33±5.51 vs 24.67±4.51, t=25.312, P<0.01]. Glucose uptake, relative lactic acid production and ATP level in the overexpression group were all higher than those in the knockdown group [(1.25±0.08) mg/ml vs (0.51±0.05) mg/ml, t=22.164, P<0.01; (44.00±3.06)% vs (19.67±3.06)%, t=25.822, P<0.01; (21.00±2.00) μmol/L vs (9.33±1.53) μmol/L, t=18.876, P<0.01]. The relative expression level of CRYAB, p-PI3K/PI3K and p-Akt/Akt proteins in the overexpression group were all higher than those in the knockdown group (6.00±0.63 vs 0.96±0.24, t=12.79, P<0.01; 2.13±0.25 vs 0.10±0.03, t=13.90, P<0.01; 2.07±0.21 vs 0.46±0.04, t=13.17, P<0.01). Conclusions:TCF12 may promote the proliferation, migration and aerobic glycolysis of colorectal cancer cells by regulating CRYAB/PI3K/Akt signaling pathway.
