OBJECTIVE To summarize the implementation experiences of the China Hospital Association’s Clinical Pharmacist Instructor Training Program Reform， and to evaluate the effectiveness of the reform， thus continuously enhancing the quality and standards of clinical pharmacist instructor training. METHODS The study drew on project evaluation methodologies to summarize the main characteristics of the comprehensive system and new model for clinical pharmacist instructor training established through the reform by literature review. The “learning assessment” and “reaction assessment” were conducted by using Kirkpatrick’s four-level model of evaluation in order to evaluate the effectiveness of the clinical pharmacist instructor training reform through statistically processing and analyzing the performance data and teaching evaluation data of the instructor participants. Based on problem and trend analysis， the future development directions were anticipated for the reform of clinical pharmacist instructor training. RESULTS & CONCLUSIONS The latest round of clinical pharmacist instructor training reform initiated by the Chinese Hospital Association had initially established a four-pronged training system encompassing “recruitment， training， assessment， and management”. It had also forged a training 。 model “oriented towards enhancing clinical teaching competency， with practical learning and skill-based assessment conducted on clinical teaching sites as its core”. Following a period of over three years of gradual reform， the new training system and model became increasingly mature. In both 2023 and 2024， the participants achieved relatively high average total scores in their initial completion assessments [with scores of （84.05± 5.83） and （85.82±4.35） points， respectively]. They also reported a strong sense of gain from the training reform [with self- perceived gain scores of （4.80±0.44） and （4.85±0.39） points， respectively]. The operation and implementation effects of the reform were generally satisfactory. In the future， clinical pharmacist instructor training reforms should continue to address the issues remaining from the current phase， while aligning with global trends in pharmacy education and industry development. Additionally， sustained exploration and practice will be carried out around the core objective of “enhancing clinical teaching competence”.

Objective:To investigate the role of Platycoside E(PE)in a mouse model of bleomycin(BLM)-induced pulmonary fibrosis by targeting the JAK/STAT signaling pathway to suppress macrophage M2 polarization.Methods:Forty BALB/c mice were randomly assigned to five experimental groups:blank control group,model group,pirfenidone(PDF)experimental group,PE high-dose group and PE low-dose experimental group,each with eight mice.After adaptive feeding,except for blank control group,all mice were used in the model of BLM nasal drip-induced pulmonary fibrosis.HE and Masson staining were employed to examine pathological alterations of lung tissue in mice;ELISA to detect concentrations of IL-10,IL-4,IL-17A and TNF-α in mice serum;expressions of CD206 and CD11b in lung tissue were detected by immunofluorescence.Western blot to detect protein expressions of JAK1,p-JAK1,STAT6 and p-STAT6 in lung tissues.Results:Compared with blank control group,tissues in model group showed distorted structure and thickened alveolar walls,fibrotic foci were formed,and alveolar inflammatory fraction and collagen volume fraction were significantly increased(P<0.01).ELISA showed that concentrations of IL-4,IL-10,IL-6 and TNF-α in serum were significantly reduced compared to those of model group.Immunofluorescence showed that fluorescence intensity of CD11b and CD206 treated by PE were decreased significantly.Western blot showed that expressions of JAK1,p-JAK,STAT6 and p-STAT6 proteins were significantly elevated in lung tissues of model mice.Following PE treatment,levels of the above proteins were diminished.Conclusion:PE can effectively improve lung fibrosis induced by BLM in mice,the mechanism may be related to the inhibition of JAK/STAT pathway to block macrophage M2 polarization.

Biomaterials provide a reliable and safe treatment for the repair of ear defects,especially microtia.With the continuous promotion of interdisciplinary research,the types and properties of materials used in auricle reconstruction have been greatly expanded and improved.In this paper,the latest research progress of polymer materials and tissue engineering scaffolds in the field of auricle reconstruction was reviewed,and the physical and chemical properties and clinical application effects of these scaffolds in vitro and in vivo were discussed.However,despite significant progress in ear stent research,there are still some challenges and limitations in the application of current polymer materials,such as the hydrophobicity of high-density polyethylene and the uncontrolled differen-tiation of stem cells in tissue engineering.Therefore,this paper discusses the research and clinical application of new modified materials,especially emphasizing the importance of surface modification technology and innovative synthesis strategies,so that the properties of modified materials are infinitely close to the characteristics of human ear cartilage.In addition,this paper also summarizes the control methods of stem cell differentiation in ear carti-lage tissue engineering.The application performance and biocompatibility of different ear scaffolds were reviewed in order to provide guidance for auricle reconstruction.

Objective This study aimed to identify PAX9 variants in non-syndromic tooth agenesis families of Chi-na,as well as to analyze the genotype-phenotype of non-syndromic tooth agenesis caused by PAX9 variants,which can provide a basis for the genetic diagnosis of tooth agenesis.Methods We collected the data of 44 patients with non-syn-dromic oligodontia who underwent treatment at Stomatological Hospital of Hebei Medical University between 2018 and 2023.Whole-exome sequencing was performed on the peripheral blood of the proband and its core family members,and the variants were verified by Sanger sequencing.Pathogenicity analysis and function prediction of the variants were per-formed using bioinformatics tools.The correlation between the genotype of PAX9 variant and its corresponding pheno-type was examined by reviewing 55 publications retrieved from PubMed.The studies involved 232 tooth agenesis pa-tients with PAX9 variants.Results A novel PAX9 c.447delG(p.Pro150Argfs*62)and a reported PAX9 c.406C>T(p.Gln136*)were identified in two Chinese families.Through bioinformatics analysis and three-dimensional structural mod-eling,we postulated that the frameshift variant was pathogenic.The outcome was the premature cessation of PAX9 pro-tein,which caused severe structural and functional deficiencies.Summarizing the PAX9 genotype-phenotype relationship revealed that patients carrying the PAX9 variant commonly led to loss of the second molars.Conclusion We identified the novel PAX9 c.447delG(p.Pro150Argfs*62)in a Chinese family of non-syndromic oligodontia,expanding the known variant spectrum of PAX9.The most susceptible tooth position for PAX9 variants of tooth agenesis was the second mo-lars and the deciduous molars during the deciduous dentition.

Gout is a metabolic disease closely associated with hyperuricemia and urate deposition. Because of the complex pathogenesis， high morbidity， multiple complications， and increasingly young patients， gout has received worldwide attention. Currently， western medicine mainly treats gout by lowering the uric acid level and reducing inflammation， which， however， causes serious adverse reactions and has contraindications. Phellodendri Chinensis Cortex （PCC） is the dried bark of Phellodendron chinense， with the effects of clearing heat， drying dampness， purging fire， detoxifying， and treating sores. Studies have shown that PCC and its active components have anti-inflammatory， pain-relieving， uric acid-lowering， and anti-gout activities， with extensive sources and high safety. PCC and its active components could prevent and treat gout through multi-targets and multi-pathways， whereas the systematic review remains to be carried out. Therefore， this paper summarized the pharmacological activities and mechanisms of PCC and its active components in the treatment of gout. The available studies have shown that PCC and its active components exert the anti-gout effect by lowering the uric acid level， reducing inflammation， alleviating oxidative stress， and regulationg intestinal flora， and protecting the kidneys. Particularly， the active components represented by alkaloids contribute obviously to the therapeutic effect of of PCC. Herein， we analyzed the problems and future development of the research on PCC， aiming to provide theoretical support and a scientific basis for the research and development of new drugs against gout.

Objective·To explore the correlation between comorbidities of chronic non-communicable diseases(chronic diseases),phase angle(PhA),and muscle mass decline associated with sarcopenia in the elderly,and the predictive value of chronic disease comorbidities and PhA in muscle mass decline in the elderly.Methods·By retrospectively screening inpatients aged≥60 years who were admitted to the Department of Geriatrics,Renji Hospital,Shanghai Jiao Tong University School of Medicine from August 1,2018 to July 31,2019,basic information and medical history of the patients(gender,age,number of medications used,number of comorbidities,presence of osteoporosis,smoking history,etc.)were collected,as well as laboratory examination indicators(hemoglobin,albumin,serum creatinine,serum uric acid,ferritin,vitamin D,triacylglycerol,total cholesterol,high-density lipoprotein,low-density lipoprotein,etc.).The age-adjusted Charlson comorbidity index(aCCI)was calculated.The InBody S10 bioelectrical impedance body composition detector was used to test the body composition.Body mass index(BMI),skeletal muscle mass index(SMI),and PhA were collected.Some patients underwent measurement of grip strength.Muscle mass decline was diagnosed by using the SMI values recommended by the 2019 Asian Working Group for Sarcopenia(AWGS)(≤7.0 kg/m2 for males and≤5.7 kg/m2 for females).According to the measured SMI values,patients were divided into a group with normal muscle mass and a group with muscle mass decline.Univariate and multivariate Logistic analyses were employed to investigate the risk factors associated with muscle mass decline related to sarcopenia in the elderly.Additionally,the receiver operator characteristic(ROC)curve and the area under the curve were utilized to predict the significance of these factors in muscle mass decline.Results·A total of 359 chronic disease patients were enrolled,including 226 males and 133 females.There were 241 cases in the normal muscle mass group and 118 cases in the muscle mass decline group.The incidence of muscle mass decline related to sarcopenia in the elderly was 32.9%.The univariate Logistic regression analysis showed that age(OR=1.036,95%CI 1.013?1.060),comorbidities(OR=1.117,95%CI 1.025?1.217),aCCI(OR=1.123,95%CI 1.031?1.222),and high-density lipoprotein(OR=3.688,95%CI 2.065?6.622)were positively correlated with the risk of muscle mass decline in the elderly.BMI(OR=0.514,95%CI 0.443?0.597),PhA(OR=0.195,95%CI 0.126?0.303),hemoglobin(OR=0.984,95%CI 0.972?0.996)and triacylglycerol(OR=0.606,95%CI 0.424?0.866)were negatively correlated with the risk of muscle mass decline in the elderly.Multivariate Logistic regression model indicated that PhA(OR=0.338,95%CI 0.119?0.959)and BMI(OR=0.634,95%CI 0.476?0.844)were negatively correlated with the risk of muscle mass decline in elderly.The area under the ROC curve for predicting muscle mass decline related to sarcopenia in elderly by using BMI and PhA was 0.893(95%CI 0.855?0.931)and 0.786(95%CI 0.736?0.837),respectively.The sensitivity was 0.724 and 0.676,respectively.The specificity was 0.916 and 0.762,respectively.When BMI combined with PhA predicted muscle mass decline in the elderly,the area under the ROC curve was 0.917(95%CI 0.883?0.951).The sensitivity was 0.867,and the specificity was 0.860.Conclusion·aCCI is correlated with muscle mass decline associated with sarcopenia in the elderly.As BMI and PhA decrease,the risk of muscle mass decline in the elderly increases.The combination of BMI and PhA has a high predictive value in muscle mass decline in the elderly.No predictive value of chronic diseases comorbidities in muscle mass decline related to sarcopenia in the elderly is found.

Objective·To investigate the current situation and distribution characteristics of chronic comorbidities,and to provide reference for further improving the self-management of comorbidities and implementing the whole course and all-round management of comorbidity.Methods·Two thousand and forty-five inpatients in the Department of Geriatrics,Renji Hospital,Shanghai Jiao Tong University School of Medicine were enrolled in this study from December 2020 to February 2023.The general vital signs,routine laboratory examination and disease status were collected.The epidemiological distribution characteristics of chronic diseases and comorbidities were analyzed.Results·The incidence of chronic diseases in the surveyed population was 99.6％,and the incidence of comorbidities was 94.2％.The top 5 chronic diseases were hypertension(43.68％),diabetes mellitus(24.81％),malignant tumor(21.48％),hyperlipidemia(18.38％)and coronary heart disease(11.99％).The detection rates of hypertension,diabetes mellitus,coronary heart disease,chronic obstructive pulmonary disease,stoke and chronic kidney disease in males were significantly higher than those in females(P＜0.05).The proportion of patients with 5 chronic diseases was the highest(11.99％),followed by 7 chronic diseases(10.26％)and 6 chronic diseases(10.04％).Among the patients of different ages,the comorbidity rate was the highest in the patients aged 50-59 years(27.78％).In different age groups,patients aged 50 to 59 with 2 chronic diseases had the highest incidence of comorbidity,which was as high as 40.82％.Although the overall proportion of comorbidities among male patients(95.37％)was higher than that among females(93.77％),there was no statistically significant difference(P=0.125).However,the proportions of male patients with 2 and 5 chronic diseases were 70.41％and 60.63％,respectively,which were significantly higher than those of female patients(29.59％and 39.37％).The correlations between coronary heart disease and diabetes mellitus,hypertension and coronary heart disease,hypertension and diabetes mellitus were higher(r=0.24,r=0.27,r=0.35,all P＜0.05).Conclusion·The prevalence of chronic diseases and comorbidities is high in the middle-aged and elderly population,and the number of comorbidities increases significantly with the increase of age.
