OBJECTIVE To systematically review the status on pharmacist competency assessment tools both domestically and internationally， providing a theoretical basis for constructing scientific and applicable pharmacist competency assessment tools in China. METHODS Through literature review and comparative analysis， 15 representative domestic and international pharmacist competency assessment tools were systematically summarized， and their theoretical foundations， core dimensions， methodological characteristics and practical applications were compared and implications were given. RESULTS &CONCLUSIONS International research has established relatively mature evaluation systems. Represented by those developed from the United Kingdom， the United States， and the International Pharmaceutical Federation， these assessment tools demonstrate scientific structure， wide application， and dynamic and international applicability. While domestic research has progressed in sub-specialties such as clinical pharmacists， licensed pharmacists and pediatric pharmacists， it still faces challenges including insufficient standardization， inadequate validation， delayed updates， and limitations in practical application. The reasons for the disparities in assessment tools between China and other countries include differences in pharmaceutical care models， varying pharmacist training systems， cultural and social background factors， as well as differences in industry management and international influence. Based on this， the author suggests promoting the development and research of assessment tools for pharmacist job competency in China from four aspects： mechanism construction， system refinement， standardization development， and practical implementation.

The doublecortin (DCX) gene encodes DCX, a microtubule-associated protein that plays a crucial role in brain development. DCX variants can disrupt microtubule binding and stabilization, interfere with intracellular transport, and affect post-translational modifications. A correlation exists between variant types and clinical severity. Animal models and induced pluripotent stem cell (iPSC) models simulating DCX deficiency revealed the dynamic progression of the disease, which has provided a powerful tool for investigating disease mechanisms and screening therapeutic agents. Currently there is no cure for DCX variants, with treatment primarily relying on anti-epileptic drugs and symptom management. Basic research is now offering new avenues for future therapeutic approaches. This article has summarized the potential pathogenic mechanisms and therapeutic strategies for the DCX variants, with an aim to provide insights for clinical treatment.

Objective:To analyze the mediating effects of psychological resilience on the relationship between perceived social support and health behavior capacity in patients with ischemic stroke.Methods:In this cross-sectional study, 500 patients with ischemic stroke were consecutively recruited using purposive sampling in the First People′s Hospital of Lianyungang between July and September in 2023. The sociodemographic characteristics, perceived social support scale, psychological resilience questionnaire and self-rated abilities for health practices scale in the patients were collected. A total of 500 questionnaires were distributed and 493 questionnaires were collected, of which 473 (95.9%) were valid. The structural equation model was constructed to explore the mediating effects of psychological resilience on the relationship between perceived social support and health behavior capacity in patients with ischemic stroke.Results:Among the 473 patients included in the analysis, there were 254 males and 219 females, with an average age of (66.8±11.4) years. The duration of stroke was less than 3 months for 329 patients (69.6%); the scores for perceived social support, psychological resilience and health behavior capacity was (59.68±11.15), (23.68±6.52), and (60.54±23.52), respectively. Perceived social support exerted significant direct effect ( β=0.334, bias-corrected 95% CI: 0.232-0.438) on health behavior capacity in patients with ischemic stroke, accounting for 63.62% of the total effect. Psychological resilience played a mediating role in the relationship between perceived social support and health behavior capacity ( β=0.191, bias-corrected 95% CI: 0.142-0.248), accounting for 36.38% of the total effect (all P<0.05). Conclusion:The health behavior capacity of patients with ischemic stroke is at a moderately low level, perceived social support may positively affect health behavior capacity through the positive mediating effect of psychological resilience.

Objective:To investigate the effect of cytoskeleton-associated protein 4 (CKAP4) gene knockout on maxillary expansion osteogenesis and its regulatory mechanism on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSC).Methods:Nineteen wild type (WT) and nineteen CKAP4 gene knockout (Ckap4 -/-) mice aged 6-8 weeks were selected to establish a mouse model of rapid maxillary expansion. Samples were taken on the 7th and 14th day after the operation. Micro-CT and HE staining were used to evaluate bone regeneration. Tissue proteins in the modeled area were collected, and Western blotting analysis (WB) was used to detect the protein expression levels of alkaline phosphatase (ALP), Runt-related transcription factor 2 (RUNX2), and osteocalcin (OCN). BMSC were isolated from WT and Ckap4 -/- mice. The expression of surface markers CD29, Sca-1, CD44, CD45, CD34, and CD11b was detected by flow cytometry, and cell proliferation ability was detected by 5-ethynyl-2'-deoxyuridine (EdU). After 7 days of osteogenic induction, real-time fluorescence quantitative PCR (RT-qPCR) and WB were used to detect the expression levels of RUXN2, ALP, OCN, protein kinase B (AKT), and phosphorylated protein kinase B (p-AKT). After 21 days, alizarin red staining and cetyl pyridine chloride quantification were used to detect the differences in mineralized nodule formation in each group. In CKAP4 gene knockout BMSC, the small-molecule AKT agonist sc79 (4 μg/ml) was added as the intervention group (Ckap4 -/- +sc79), and dimethyl sulfoxide (DMSO) treatment was used as the control group (Ckap4 -/- +DMSO). After osteogenic induction, RT-qPCR, WB, and alizarin red staining were used to compare the osteogenic differentiation differences between the two groups of cells. Results:The micro-CT results showed that at 7 days and 14 days after surgery, the new bone volume in the Ckap4 -/- group [(0.070±0.010) and (0.146±0.019) mm 3] was significantly lower than that in the WT group [(0.094±0.006) and (0.196±0.013) mm 3] (both P<0.01). HE-stained histological sections showed that the area of new bone tissue in the Ckap4 -/- group at 7 days and 14 days after surgery [(0.101±0.008) and (0.158±0.010) mm 2] was also significantly lower than that in the WT group [(0.116±0.005) and (0.183±0.008) mm 2] (both P<0.05). WB was used to detect the tissue proteins in the maxillary modeling area of mice in the two groups 7 days after surgery. The results showed that the expression levels of ALP, RUNX2 and OCN in the Ckap4 -/- group were significantly lower than those in the WT group. BMSC from wild-type mice and CKAP4 knockout mice were both positively expressed for CD29, CD44, and Sca-1, and basically not expressed for CD45, CD34, and CD11b. EdU assay showed that there was no significant difference in the proliferation ability of cells in the two groups. After 21 days of osteogenic induction of BMSC, alizarin red staining results showed that the number of mineralized nodules in the Ckap4 -/- group was significantly less than that in the WT group. After adding sc79, the number of mineralized nodules increased significantly, which was consistent with the results of cetyl pyridine chloride quantification. After 7 days of osteogenic induction, It was found that the expression levels of ALP, RUNX2, and OCN in the CKAP4 -/-group (0.751±0.066, 0.484±0.040, 0.679±0.063) were significantly lower than those in the WT group (1.000±0.113, 1.000±0.081, 1.000±0.113) (all P<0.001). The results of WB were consistent with those of RT-qPCR. At the same time, the WB results showed that the level of p-AKT protein in the CKAP4 -/-group (0.518±0.114) was significantly lower than that in the WT group (1.000±0.234) ( P<0.05). After treatment with sc79 for 7 days of osteogenic induction, RT-qPCR was used to detect the gene expression levels of ALP, RUNX2, and OCN. The results showed that the expression levels in the CKAP4 -/-+sc79 group (2.755±0.353, 4.800±0.990, 2.524±0.137) were significantly higher than those in the CKAP4 -/-+DMSO group (1.000±0.078, 1.000±0.247, 1.000±0.175) (all P<0.001). Conclusions:CKAP4 knockout inhibits the osteogenic differentiation of BMSC by reducing the activity of the PI3K/AKT signaling pathway, thereby suppressing osteogenesis in maxillary expansion.

Objective:To evaluate the clinical efficacy and safety of dupilumab in the treatment of pediatric prurigo nodularis (PN), and to explore factors associated with the treatment response.Methods:A retrospective analysis was conducted on clinical data from 26 children with PN who received dupilumab treatment at the Institute of Dermatology and Venereology, Sichuan Provincial People's Hospital between December 2022 and January 2025. Primary efficacy endpoints were the proportion of patients achieving investigator's global assessment-activity (IGA PN-A) and stage (IGA PN-S) scores of 0/1 at week 8; secondary efficacy endpoints included the proportion of patients achieving a ≥ 4-point reduction in the pruritus numerical rating scale (NRS) and changes in laboratory parameters. Paired t tests or Wilcoxon signed-rank tests were used for pre- and post-treatment comparisons; generalized estimating equation models were applied to evaluate changes in eczema area and severity index (EASI) scores over time; univariate logistic regression analysis was performed to calculate odds ratios ( ORs) and 95% confidence intervals ( CIs) to analyze factors influencing efficacy. Results:Among the 26 children with PN, 14 (53.8%) were males and 12 (46.2%) were females, with ages ( M[ Q1, Q3]) of 4.50 (3.00, 9.25) years and disease duration of 1.00 (0.48, 2.25) years. Twenty-four (92.3%) patients had comorbid atopic diseases, including 17 with allergic rhinitis and 15 with atopic dermatitis (AD). At week 8, IGA PN-A scores decreased from 3.27 ± 0.53 points at baseline to 1.31 ± 0.84 points ( t = 10.44, P < 0.001), with 16 (61.5%) patients achieving IGA PN-A 0/1; IGA PN-S scores decreased from 3.15 ± 0.46 points at baseline to 1.73 ± 0.78 points ( t = 10.33, P < 0.001), with 10 (38.5%) patients achieving IGA PN-S 0/1; pruritus NRS scores decreased from 5.00 (5.00, 6.00) points at baseline to 2.00 (1.00, 3.00) points ( Z = -3.82, P < 0.001), with 10 (38.5%) patients achieving a ≥ 4-point reduction in NRS scores. At week 40, 7 patients who continued treatment achieved complete remission. Univariate logistic regression showed that head/face involvement ( OR = 7.000, 95% CI: 1.200 - 40.829) and disease duration of < 1 year ( OR = 7.000, 95% CI: 1.200 - 40.829) were associated with better treatment response, while baseline IGA scores of 4 points predicted poorer outcomes ( OR = 0.114, 95% CI: 0.017 - 0.742). During treatment, conjunctivitis and local infection occurred in 2 cases without discontinuation, and no serious adverse events occurred in any of the cases. Conclusions:Dupilumab demonstrated rapid and sustained efficacy in pediatric PN with a favorable safety profile. Head/face involvement, shorter disease duration, and lower baseline severity were associated with better treatment response.

Objective:To observe the incidence of early blood eosinophils (Eos) elevation in patients with peritoneal dialysis (PD), analyze its related factors, and its relationship with early-onset peritonitis in PD patients.Methods:This study was a retrospective observational cohort study. Patients who underwent PD catheterization in Peking University People's Hospital from January 2012 to December 2022 were included. After surgery, PD treatment was started immediately and followed up regularly ≥12 months. The general information and laboratory indexes collected 1 week before catheterization, and at 1, 3, 6 and 12 months after catheterization were recorded. The occurrence of elevated blood Eos (≥0.5×10 9/L) during the early stage of PD, the related factors of Eos elevation (≥0.5×10 9/L) and the relationship with early-onset peritonitis (within 12 months after PD initiation) were analyzed. Results:(1) A total of 235 patients were enrolled, with an age of (57.9.±13.9) years, including 136 males (57.9%). The primary diseases were predominantly chronic glomerulonephritis (111/235, 42.7%) and diabetic nephropathy (83/235, 35.3%). During the 12-month follow-up period, 73 patients had elevated blood Eos (31.1%), of which 37 cases (50.7%) occurred within 1 month after PD catheterization, 21 cases (28.7%) occurred 2-3 months after PD catheterization, 12 cases (16.4%) occurred 4-6 months after PD catheterization, and 3 cases (4.1%) occurred 7-12 months after PD catheterization. In 73 patients with elevated Eos, 69 cases (94.5%) were mildly elevated, 4 cases (5.5%) were moderately elevated. As for the duration of elevated blood Eos, 28 cases (38.4%) lasted less than 1 month, 27 cases (37.0%) lasted 1-3 months, and 18 cases (24.7%) lasted more than 3 months. (2) In patients with elevated blood Eos, the proportion of male patients (71.4% vs. 52.1%, χ 2=7.515, P=0.006), the proportion of diabetes mellitus (55.7% vs. 41.2%, χ 2=4.168, P=0.046), and the proportion of combined vascular disease (32.9% vs. 18.2%, χ 2=6.060, P=0.017) were significantly higher than those patients in normal blood Eos group. (3) Multivariate Logistic regression analysis showed that male was an independent related factor for elevated blood Eos (≥0.5×10 9/L) in the early stages of PD ( OR=2.044, 95% CI 1.101- 3.794, P=0.023). (4) Diabetes mellitus ( OR=3.363, 95% CI 1.087-10.405, P=0.035), lower baseline hemoglobin level ( OR=0.941, 95% CI 0.903-0.980, P=0.004) and elevated blood Eos (with serum Eos<0.5×10 9/L as reference, OR=2.917, 95% CI 1.022-8.326, P=0.045) were the independent related factors of early-onset peritonitis. Conclusion:Blood Eos elevations are common in early stage of PD patients , mainly occuring within 6 months after PD catheterization, and most of them are slightly increased and last less than 3 months. Male sex is an independent related factor for the elevation of blood Eos in the early stage of PD. Elevated blood Eos is an independent related factor for early-onset peritonitis.

Objective:To analyze the problems in implementing medical-research-industry collaborative innovation related policies, and propose corresponding countermeasures, for references for promoting the construction and development of collaborative innovation platforms in China.Methods:This study searched official websites such as the State Council, the National Health Commission and the Shanghai Municipal Health Commission for policy documents related to collaborative innovation and the transformation of medical scientific and technological achievements. Based on the Smith-model, 4 plaiforms of Shanghai were took, including the Clinical Science and Technology Innovation Park of Tongji University of Tenth People′s Hospital and other collaborative innovation platforms, as examples to analyze the problems in the implementation process of medical-research-industry collaborative innovation policies.Results:On the basis of national policies, Shanghai had issued a series of relevant guidance policies based on local conditions, creating a favorable policy environment for the construction and development of the medical-research-industry collaborative innovation platforms. However, the policy implications and practical needs related to collaborative innovation still needed to be continuously adjusted; The target demands of policy implementation entities were not unified, and there was a lack of normalized communication mechanisms; The target group lacked endogenous motivation and the policy implementation environment needed to be improved.Conclusions:The implementation of medical-research-industry collaborative innovation policies needed further improvement. It is suggested to optimize the policy supply coordination, performance evaluation and incentive mechanism, supervision and management, collaborative innovation culture atmosphere, and multi-channel funding support to promote the sustainable development of the collaborative innovation platform, and accelerate the efficient transformation of scientific and technological achievements.

Objective:To evaluate the feasibility and efficacy of our self-designed intelligent robot-assisted reduction system for fresh subtrochanteric fractures of the femur.Methods:A retrospective cohort study was conducted to include 10 patients with fresh subtrochanteric fracture of the femur who had been admitted to Department of Orthopedic Trauma, Beijing Jishuitan Hospital from January 2024 to July 2024. There were 7 males and 3 females with an age of (45.0±14.3) years and an interval from injury to surgery of (7.9±3.7) d. All the patients were treated by minimally invasive reduction which was assisted by our self-designed intelligent robot, and internal fixation with intramedullary nails. The operation duration, intraoperative reduction duration, intraoperative blood loss, and intraoperative fluoroscopy frequency were recorded. The reduction effect was evaluated by calculating the differences between preoperative planning and postoperative CT reconstruction (i.e., the differences in femoral shaft length and in rotation angle). The hip functional recovery was assessed by Harris hip function Scoring.Results:The mean operation time was 200.0 (161.3, 217.5) min, the reduction time (83.0±35.5) min, the intraoperative blood loss (290.0±110.1) mL, and the intraoperative fluoroscopy 18.5 (9.0, 19.3) times. In all patients, the difference in femoral shaft length was (2.4±1.4) mm, and the difference in rotation angle 5.1°±3.0°. All patients were followed up for (8.2±2.0)months. All the fractures got united at the last follow-up. Their Harris hip function score was (83.3±4.1) points.Conclusion:Our self-designed intelligent robot-assisted reduction system is feasible and effective in the surgery of fresh subtrochanteric fracture of the femur, because the robot system can complete the autonomous planning of reduction approaches before surgery and assist fracture reduction under real-time monitoring with three-dimensional images, leading to fine outcomes.

Objective:To investigate the effects of influenza A virus(IAV)on macrophages based on expression of cytokines mediated by Janus kinase/signal transducer and activator of transcription(JAK/STAT)pathway,and to further explore the intervention effects of Ma Xing Shigan decoction drug containing serum.Methods:RAW264.7 was divided into control group,JAK/STAT signal pathway activator group,inhibitor group,model group,oseltamivir group,antiviral granule group and Ma Xing Shigan decoction group.Cell samples were collected after the intervention of IAV and subsequent treating of drug-containing serum for 24 and 48 hours.Secretion levels of IL-1β and CXCL2 in supernatant were detected by ELISA.mRNA expression levels of influenza virus Nuclear Pro-tein(NP),JAK1/2 and STAT1 of cells were detected by RT-qPCR.Protein expression levels of JAK1/2 and STAT1 were detected by Western blot,and protein expression levels of p-STAT1 was detected by immunofluorescence.Correlation between protein expression levels of p-STAT1 and secretion of IL-1β and CXCL2 were evaluated by Pearson correlation analysis.Results:Secretion levels of IL-1β and CXCL2,mRNA expression levels of NP,JAK1/2,STAT1,protein levels of JAK1/2,STAT1 and p-STAT1 were increased,and protein levels of p-STAT1 was positively correlated with the secretion of IL-1β and CXCL2.Ma Xing Shigan decoction could down-regulate secretions of IL-1β and CXCL2,mRNA expression levels of NP,JAK1/2 and STAT1,protein expression levels of JAK1,JAK2,STAT1 and p-STAT1.Conclusion:Activation of JAK1/2-STAT1 signal pathway and imbalance of inflammatory factors may be one of the molecular mechanisms of immunopathological damage of macrophages induced by IAV.Ma Xing Shigan decoction may alle-viate pathogenic effects of IAV by regulating this signal pathway.

Objective To describe the clinical features of patients with primary sclerosing cholangitis(PSC)in China based on a nationwide multicenter patient cohort,and to investigate the risk factors for prognosis.Methods A retrospective cohort study was conducted among the patients with a confirmed diagnosis of PSC based on the electronic medical record system of seven grade A tertiary hospitals across the country,and related data were extracted.The Mann-Whitney U test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.The Kaplan-Meier method was used to estimate liver transplant-free survival,and the log-rank test was used for comparison of survival rate between PSC patients with different features.The Cox regression model was used to identify independent risk factors for the prognosis of PSC patients and the interactions between key factors.Results A total of 107 patients were enrolled,among whom 55.6%(55/99)had large-duct PSC and 29.0%(31/107)had comorbidity with inflammatory bowel disease(IBD).The positivity rate of anti-neutrophil cytoplasmic antibody(ANCA)was 32.9%(24/73),and 50.0%(40/80)of the patients had an increase in IgG/IgM.The median symptom-to-diagnosis interval was 1 year(<1-4.0),and 38.3%(41/107)of the patients had progressed to decompensated cirrhosis at the time of diagnosis.The median liver transplant-free survival time was 114 months(95%confidence interval[CI]:62-166),with a 5-year survival rate of 65.7%.The multivariate analysis showed that an increase in total bile acid(TBA)(hazard ratio[HR]=1.006,95%CI:1.002-1.010,P=0.001)and a prolonged symptom-to-diagnosis interval(HR=1.252,95%CI:1.059-1.480,P=0.009)were independent risk factors for prognosis.The interaction analysis showed that compared with the female patients with TBA<50 μmol/L,both male and female patients with TBA≥50 μmol/L had a significant increase in the risk of liver transplantation or death(male:HR=16.563,95%CI:2.103-130.449,P<0.001;female:HR=17.009,95%CI:2.113-136.934,P<0.001),and compared with the patients with an age of<45 years and a TBA level of<50 μmol/L,the patients with an age of≥45 years and a TBA level of≥50 μmol/L had a significant increase in the risk of liver transplantation or death(HR=10.729,95%CI:1.325-86.859,P=0.026).Compared with the female patients with an symptom-to-diagnosis interval of≤2 years,the male patients with a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.825,95%CI:1.725-13.644,P=0.003),and compared with the patients with an age of<45 years and a symptom-to-diagnosis interval of≤2 years,the patients with an age of<45 years and a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.983,95%CI:1.366-18.173,P=0.015).Conclusion Compared with the reports from Western countries,large-duct PSC is also the main type of PSC in China,but with a relatively low proportion,and there is also a relatively low proportion of patients with IBD or positive ANCA.An increase in TBA and a prolonged symptom-to-diagnosis interval are independent risk factors for prognosis,with significant interactions with age and sex.This suggests that early screening and intervention should be enhanced to improve prognosis.
