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.

ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction (小青龙汤, XD) in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group, a model group, a loratadine group, low-, medium- and high-dose XD groups, and low-, medium- and high-dose Mahuang Decoction and Cang'erzi Powder (麻黄汤合苍耳子散, MDCP) groups. Except for the control group, rats were administered with ovalbumin (OVA) and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection, nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/(kg·d) of saline, whereas those in the loratadine group were administered with 0.9 mg/(kg·d) of loratadine. The low-, medium- and high-dose XD groups were administered XD at the dose of 2.7, 5.4, and 10.8 g/(kg·d), respectively. The low-, medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43, 4.86, and 9.72 g/(kg·d), respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage, nasal symptom scores were recorded for all group of rats. The next day, serum levels of immunoglobulin E (IgE), interleukin-4 (IL-4), and interleukin-13 (IL-13) were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR (RT-qPCR) and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin (TSLP) and OX40 ligand (OX40L) in the nasal mucosa. ResultsCompared to the control group, total nasal symptom score in the model group significantly increased (P<0.01). HE staining revealed disrupted and adhered cilia, thickened basement membranes, and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE, IL-4, and IL-13, as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa, were significantly elevated in the model group (P<0.05 or P<0.01). Compared to the model group, the total nasal symptom scores in all drug intervention groups were significantly reduced; the serum total IgE levels in the loratadine group, the low- and medium-dose XD groups, and the low- and high-dose MDCP groups were significantly reduced; and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased (P<0.05 or P<0.01). Nasal mucosal structure was improved. Except for the low-dose MDCP group, all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa (P<0.01). All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L (P<0.05). The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA, and TSLP protein levels compared to the loratadine group (P<0.05). ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway, thereby attenuating Th2-mediated immune responses.

Objective To investigate the impact of nucleophosmin 1-mutated(NPM1m)subtypes,variant allele frequency(VAF)and co-mutations on the survival outcomes of patients with acute myeloid leukemia(AML).Methods Clinical data,mutation status,and outcomes of 86 NPM1m-AML patients admitted in Department of Hematology,First Hospital of Lanzhou University between June 2017 and September 2024 were collected and retrospectively analyzed.Spearman correlation analysis,Kaplan-Meier curve analysis,Log-rank test,and Cox regression analysis was applied for correlation analysis,survival analysis,and factors affecting survival.Results The overall survival(OS)was significantly shorter in the Rares subtype of NPM1m than the ABD subtype(median OS:164 d vs 416 d,P=0.043).The VAF of NPM1m was positively correlated with the initial peripheral blood white blood cell count and lactate dehydrogenase(LDH)level(P<0.05).OS was reduced when VAF was≥0.37(median OS:164 d vs 730 d,P=0.003).The presence of myelodysplasia-related gene(MR)mutations was associated with a poorer prognosis when compared to the MR wild-type(median OS:45 d vs 395 d,P<0.001).The triple mutation of FMS-like tyrosine kinase 3-internal tandem duplication(FLT3-ITD)and DNMT3A also indicated a worse prognosis than the non-triple mutation(median OS:173 d vs 483 d,P=0.007).The presence of PTPN11 mutations was associated with improved OS(median OS:395 d vs 240 d,P=0.027),while the patients with coexistence of N/KRAS mutations trended toward better prognosis than the wild-type patients(median OS:662 d vs 189 d)though no statistical significance(P=0.070).Multivariate analysis revealed that LDH(HR=1.002,95%CI:1.000~1.003,P=0.005),NPM1m VAF(HR=2.415,95%CI:1.208~4.829,P=0.013),Rares subtype(HR=3.037,95%CI:1.134~8.136,P=0.027),and MR mutations(HR=5.283,95%CI:1.991~14.017,P<0.001)were independent risk factors associated with OS in the patients.Conclusion Molecular heterogeneity of NPM1m should be taken into account in prognostic stratification of NPM1m-AML.Factors including the Rares subtype,VAF≥0.37,coexistence of FLT3-ITD and DNMT3A mutations,and MR mutations are associated with poor prognosis of NPM1m-AML.The presence of PTPN11 mutations improves the prognosis,while the presence of N/KRAS mutations shows a trend toward better prognosis.LDH,NPM1m VAF,Rares subtype,and MR mutations are independent risk factors affecting OS of patients with NPM1m-AML.

Objective:
To determine the clinical efficacy and mechanism of Piwei Peiyuan Pill (PPP) combined with moxibustion for treating patients with chronic atrophic gastritis (CAG) with spleen and stomach weakness syndrome.
Methods:
Ninety-six CAG patients with spleen and stomach weakness syndrome who met the inclusion and exclusion criteria were enrolled at the Department of Spleen and Stomach Diseases of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to December 2023. The patients were randomly divided into a control, a Chinese medicine, and a combined group using a random number table method, with 32 cases in each group (two cases per group were excluded). The control group was treated with rabeprazole combined with folic acid tablets (both thrice daily), the Chinese medicine group was treated with PPP (8 g, thrice daily), and the combined group was treated with moxa stick moxibustion (once daily) on the basis of the Chinese medicine group for 12 consecutive weeks. Gastric mucosa atrophy in the three groups was observed before and after treatment. The gastric mucosal pathological score was evaluated. The Patient Reported Outcome (PRO) scale was used to evaluate the patients′ physical and mental health status and quality of life.An enzyme-linked immunosorbent assay was used to detect serum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4, IL-10, IL-37, and transforming growth factor (TGF)-β levels in each group. Real-time fluorescence PCR was used to detect the relative expression levels of signal transducer and activator of transcription 3 (STAT3) and mammalian target of rapamycin (mTOR) mRNA in each group. Western blotting was used to detect the relative expression levels of proteins related to the STAT3/mTOR signaling pathway, and the adverse drug reactions and events were recorded and compared.
Results:
There was no statistical difference in age, gender, disease duration, family history of gastrointestinal tumors, alcohol consumption history, and body mass index among the three groups of patients.The total therapeutic efficacy rates of the control, Chinese medicine, and combined groups in treating gastric mucosal atrophy were 66.67% (20/30), 86.67% (26/30), and 90.00% (27/30), respectively (P<0.05). Compared to before treatment, the pathological and PRO scale scores of gastric mucosa in each group decreased after treatment, and TNF-α, IL-1β, IL-37, and TGF-β levels decreased. The relative STAT3 and mTOR mRNA expression levels, as well as the relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels decreased (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the control group, the pathological score of gastric mucosa, PRO scale score, TNF-α, IL-1β, IL-37, TGF-β content, relative STAT3 and mTOR mRNA expression levels, and relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels in the Chinese medicine and combined groups after treatment were reduced (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the Chinese medicine group, the combined group showed a decrease in relative STAT3, mTOR mRNA expression levels, and STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels (P<0.05).
Conclusion
The combination of PPP and moxibustion may regulate the inflammatory mechanism of the body by inhibiting the abnormal activation of the STAT3/mTOR signaling pathway, upregulating related anti-inflammatory factor levels, downregulating pro-inflammatory factor expression, and increasing related repair factor expression, thereby promoting the recovery of atrophic gastric mucosa, reducing discomfort symptoms, and improving the physical and mental state of CAG patients with spleen and stomach weakness syndrome.

OBJECTIVE To analyze the efficacy and safety of luspatercept in the treatment of myelodysplastic syndromes (MDS) anemia, and provide reference for clinical medication. METHODS The literature related to luspatercept for MDS anemia in PubMed, Cochrane Library, Embase and Web of Science were searched by computer, and the search time was from the establishment of the database to January 2024. The quality of literature was evaluated after they were screened according to inclusion and exclusion criteria, the single-group rate meta-analysis and sensitivity analysis were performed by using RevMan 5.4 software, and the subgroup analysis was conducted. RESULTS A total of 756 patients in 9 articles were included in this study. The results of meta-analysis showed that the proportion of MDS patients who reached ≥8 weeks of red blood cell transfusion independence (RBC-TI) was 46% after using luspatercept [95%CI (0.28, 0.64), P<0.000 01]. The proportion of MDS patients whose hematological improvement in erythrocyte (HI-E) was 59% [95%CI (0.43, 0.74), P<0.000 01]. Among them, 5 articles reported that the proportion of MDS patients with grade 3-4 adverse reactions was 14% [95%CI (0.07, 0.22), P=0.000 2], and the poor general condition, infection, blood and lymphatic system disease were the common adverse reactions. Subgroup analysis showed that the source of heterogeneity was the blood transfusion burden in the proportion of MDS patients with RBC-TI≥8 weeks, and the source of heterogeneity was the 0931-8356251。revised international prognostic scoring system (IPSS-R) risk grade, SF3B1 mutation status and blood transfusion burden in the proportion of MDS patients with HI-E. Sensitivity analysis showed that the results of this study were stable. CONCLUSIONS Luspatercept can significantly improve blood transfusion dependence, reduce blood transfusion burden and promote hematology improvement in MDS patients. But attention should be paid to the occurrence of grade 3-4 adverse events; adverse events such as poor general condition, infection, blood and lymphatic system diseases are more common.

OBJECTIVES:
This study aimed to explore the impact of cell spreading area on odontoblast polarization and differentiation using micropatterned surfaces ge-nerated by photolithography.
METHODS:
Micropatterned surfaces with differential adhesive properties were prepared using polyethylene glycol diacrylate (PEGDA)-ba-sed photolithography. Human dental pulp stem cells (hD-PSCs) were isolated into single cells and cultured on micropatterned surfaces with areas of 1 800, 2 700, and 3 600 μm2. Immunofluorescence staining was used to observe cell morphology and analyze the relocating of the golgi apparatus and nucleus. Alkaline phosphatase staining was preformed to examine odontogenic differentiation.
RESULTS:
The hDPSCs were successfully isolated and cultured on micropatterned surfaces mimicking the morphology of polarized odontoblasts. Phalloidin staining confirmed that the isolated hDPSCs successfully recapitulated the morphology of predesigned micropatterns. Immunofluorescence staining showed that the polarization and differentiation levels of the hDPSCs with a 3600 μm2 area were significantly higher than those with 1 800 and 2 700 μm2 areas (P<0.05).
CONCLUSIONS
The polarization and differentiation of single hDPSCs increased with the cell areas on micropatterned surfaces.

OBJECTIVE:
To investigate the effect of zedoarondiol on neovascularization of atherosclerotic (AS) plaque by exosomes experiment.
METHODS:
ApoE-/- mice were fed with high-fat diet to establish AS model and treated with high- and low-dose (10, 5 mg/kg daily) of zedoarondiol, respectively. After 14 weeks, the expressions of anti-angiogenic protein thrombospondin 1 (THBS-1) and its receptor CD36 in plaques, as well as platelet activation rate and exosome-derived miR-let-7a were detected. Then, zedoarondiol was used to intervene in platelets in vitro, and miR-let-7a was detected in platelet-derived exosomes (Pexo). Finally, human umbilical vein endothelial cells (HUVECs) were transfected with miR-let-7a mimics and treated with Pexo to observe the effect of miR-let-7a in Pexo on tube formation.
RESULTS:
Animal experiments showed that after treating with zedoarondiol, the neovascularization density in plaques of AS mice was significantly reduced, THBS-1 and CD36 increased, the platelet activation rate was markedly reduced, and the miR-let-7a level in Pexo was reduced (P<0.01). In vitro experiments, the platelet activation rate and miR-let-7a levels in Pexo were significantly reduced after zedoarondiol's intervention. Cell experiments showed that after Pexo's intervention, the tube length increased, and the transfection of miR-let-7a minics further increased the tube length of cells, while reducing the expressions of THBS-1 and CD36.
CONCLUSION
Zedoarondiol has the effect of inhibiting neovascularization within plaque in AS mice, and its mechanism may be potentially related to inhibiting platelet activation and reducing the Pexo-derived miRNA-let-7a level.
