Objective To investigate the effects of open reading frame 1 protein(ORF1p),encoded by long interspersed nuclear element-1(LINE-1),on the proliferation,migration,and invasion of esophageal squamous cell carcinoma(ESCC)cells,and explore the underlying molecular mechanism.Methods① Western blotting was performed to compare the expression of ORF1p between normal esophageal squamous epithelial cells and ESCC cells.② Immunohistochemistry(IHC)assay was used to examine ORF1p expression in ESCC tissues and paired normal tissues adjacent to tumor.③ The effects of ORF1p knockdown and overexpression on malignant behaviors in ESCC cells were determined through functional assays.④ Xenograft tumor model in nude mice was established to evaluate the impact of ORF1p on tumor growth in vivo.⑤ Transcriptome sequencing combined with cell functional rescue experiments were conducted to identify downstream targets regulated by ORF1p.Results ① Western blot analysis demonstrated the expression of ORF1p was significantly higher in the ESCC cell lines than the normal esophageal squamous epithelial cells(P<0.05).② IHC confirmed remarkable up-regulation of ORF1p in ESCC tissues than paired adjacent normal tissues(P<0.000 1).③ Functional assays and experiments on xenograft tumor models revealed that ORF1p substantially enhanced the proliferation,migration,and invasion of ESCC cells,as well as tumorigenic potential in vivo(P<0.05).④ Functional rescue experiments showed that ORF1p facilitated the proliferation,migration,and invasion of ESCC cells by modulating AJUBA expression(P<0.05).Conclusion ORF1p is significantly up-regulated in ESCC and promotes the proliferation,migration,and invasion of ESCC cells by regulating AJUBA expression.

Objective To develop a machine learning model integrating preoperative chest CT radiomic features with clinical data for predicting 5-year postoperative recurrence risk in stage Ⅰ non-small cell lung cancer(NSCLC)patients undergoing surgical resection.Methods A total of 217 patients with pathologically confirmed stage Ⅰ NSCLC(selected from 778 initially screened cases based on our inclusion and exclusion criteria)treated in Army Medical Center of PLA between January 2014 and December 2019 were retrospectively enrolled,including 53 recurrence cases and 164 non-recurrence cases within 5-year follow-up.They were randomly divided into a training set(n=173)and a validation set(n=44)in a ratio of 8:2.Radiomic models were established based on extracted features from tumor-dominant regions of interest(ROI)on CT images,while clinical models were developed using demographic characteristics and preoperative laboratory examinations.A combined model was further constructed by integrating both feature sets,and model performance was compared to identify the optimal predictive model.Results This study screened the features from non-contrast CT images and ultimately selected 7 radiomic features for constructing radiomic model.Among 6 machine learning algorithms,the adaptive boosting(Adaboost)model demonstrated the best overall predictive performance,with an area under the curve(AUC)of 0.866(95%CI:0.808～0.923;accuracy:0.832,specificity:0.884)in the training set and of 0.806(95%CI:0.630～0.983;accuracy:0.795,specificity:0.971)in the validation set.Univariate and multivariate logistic regression analyses identified 4 clinical features for clinical model construction.The clinical model achieved an AUC value of 0.874(95%CI:0.821～0.928;accuracy:0.827,specificity:0.891)in the training set and 0.813(95%CI:0.677～0.948;accuracy:0.636,specificity:0.600)in the validation set.By integrating the 7 radiomic features and 4 clinical features using a feature-level fusion strategy,the combined model exhibited further improved predictive performance,with an AUC value of 0.953(95%CI:0.924～0.983;accuracy:0.884,specificity:0.860)and 0.852(95%CI:0.729～0.976;accuracy:0.682,specificity:0.629),respectively in the training set and the validation set.Conclusion The combined model integrating preoperative CT radiomic features with clinical risk factors may provide an evidence-based framework for evaluating 5-year postoperative recurrence risk in stage Ⅰ NSCLC patients.

Objective To investigate and analyze the relationship between bone metabolism indicators,bone mineral density(BMD)T value,osteoporosis and fracture risk in patients with type 2 diabetes mellitus(T2DM).Methods A retrospective analysis was conducted on the clinical data of 175 patients with T2DM ad-mitted to the hospital from January to August 2024.According to the T value,they were divided into the oste-oporosis group(n=65),the osteopenia group(n=50),and the normal bone mass group(n=60).The general clinical data and bone metabolism indicators were compared among the three groups,including 25-hydroxyvi-tamin D3[25-(OH)D3],osteocalcin(OC),calcitonin(CT),type Ⅰ procollagen amino-terminal peptide(PⅠNP)and β-collagen degradation products(β-CTX),parathyroid hormone(PTH),T value,and the differences between the fracture risk assessment tools[FRAX,including 10-year major osteoporotic fracture(MOF)risk and 10-year hip fracture(HF)risk],analyzed the influencing factors of osteoporosis in T2DM patients,as well as the relationship between bone metabolism indicators,T values and fracture risk.Results The results of un-ivariate and multivariate logistic regression analyses showed that PⅠNP and β-CTX were risk factors for oste-oporosis in patients with T2DM,while estradiol(E2),testosterone(T),25-(OH)D3,OC,and T values were all protective factors(P<0.05).The 10-year risks of MOF and HF in the osteoporosis group were higher than those in the osteopenia group and the normal bone mass group,while the 10-year risks of MOF and HF in the osteopenia group were higher than those in the normal bone mass group,the differences were statistical-ly significant(P<0.05).According to Pearson correlation analysis,25-(OH)D3 and T values were negatively correlated with the risks of 10-year MOF and HF,while OC,PⅠNP,and β-CTx were positively correlated with the risks of 10-year MOF and HF(P<0.05),CT and PTH were not correlated with the risks of 10-year MOF and HF(P>0.05).Conclusion Bone metabolism indicators and BMD are important influencing factors for the occurrence of osteoporosis in patients with T2DM,and they are closely related to the occurrence of os-teoporotic fractures.Clinically,the monitoring of bone metabolism and BMD in patients with T2DM should be strengthened.

Objective:To investigate the association of the interaction and combined effect of renal function and body mass index (BMI) with the risk for all-cause death in patients with type 2 diabetes mellitus (T2DM) in communities of Jiangsu Province.Methods:The study subjects were from the Comprehensive Research Project of Diabetes Prevention and Control conducted in Jiangsu from December 2013 to January 2014, and follow up was conducted for them until September 30, 2023. A total of 20 025 subjects were included in the study. Cox proportional hazards regression model was used to analyze the association of renal function with risk for death in T2DM patients, and the association of interaction between renal function and BMI and their combined effect with all-cause death risk in T2DM patients.Results:In the follow up for 198 370 person-years, a total of 4 459 deaths were recorded. Cox proportional hazards regression model analysis showed that renal dysfunction was associated with 71% risk of all-cause mortality in all T2DM patients [hazard ratio ( HR) =1.71, 95% CI: 1.59-1.84], as well as in all BMI subgroups. Likelihood ratio test indicated an interaction between renal function and BMI (interaction for P=0.030). Compared with patients with normal renal function and normal BMI, those with normal renal function and over weight or obesity had a lower risk of all-cause mortality, and those with renal dysfunction and low weight had the highest risk for death ( HR=2.78, 95% CI: 1.87-4.14). Conclusions:There is association of interaction between renal function and BMI with all-cause mortality in T2DM patients. T2DM patients with renal dysfunction and low body weight had significant higher risk for death.

OBJECTIVE：To unscramble the Notice on Standardizing the Allocation and Use of Licensed Pharmacists in Drug Retail Enterprises （called Notice for short ）and related document ，and to give some suggestions to provide reference for the industry and policy decision departments. METHODS ：The background and content of Notice were described briefly ；the problemsexisting in the corresponding provincial differentiated allocation policy and the difficulties existing in the implementation were analyzed to give some relevant suggestions. RESULTS & CONCLUSIONS ：The main contents of Notice contained adhering to the policy of licensed pharmacists ，steadily improving the allocation level of licensed pharmacists ，refining and implementing the allocation requirements ，and strengthening the implementation of supervision and inspection responsibilities ；giving full play to the role of licensed pharmacists and continuously strengthening the team building. At present ，drug administrations of many provinces in China have issued specific policies on the differentiated allocation of licensed pharmacists and pharmaceutical technicians ，which are mainly divided into four schemes. The author believes that the classification method of drug retail enterprises implemented in Shandong and Guangdong provinces are the most scientific. The implementation of differentiated allocation of pharmacists with health（pharmacy）professional title in drug retail enterprises can alleviate the problem of insufficient licensed pharmacists to a certain extent ，but the disadvantage is that it can not achieve accurate registration and control as well as the management of licensed pharmacists ，which is easy to produce policy gaps ；after the “affiliation licensed pharmacist ’s certificate ”phenomenon， the“certificate affiliation of pharmacist with health （pharmacy）professional title ”phenomenon appeared. It is suggested that the provincial drug supervision and administration departments should try the differentiated allocation scheme of hierarchical management；learn from the management experience of licensed pharmacists and pharmaceutical technicians in Guangdong province， develop relevant platforms to manage the information of pharmaceutical technicians uniformly ； strengthen the communication and interaction with the health and human resource security department as well as the mutual promotion mechanism of personnel information screening ，so as to solve the core bottleneck of licensed pharmacists ’quality.
