OBJECTIVE To investigate the current status of self-medication behaviors and the demand preferences for pharmaceutical services among residents in Xining， providing a basis for developing pharmaceutical service intervention strategies tailored to regional characteristics. METHODS A self-designed questionnaire， developed based on literature review and revised after expert panel discussion and a pre-survey， was used to conduct anonymous surveys among residents purchasing medicines at 12 retail pharmacies in Xining area from April 2023 to April 2024. Descriptive analysis， Chi-square test， and Spearman correlation analysis were employed to analyze the characteristics and influencing factors of residents’ self-medication behaviors， and pharmaceutical service needs. RESULTS A total of 859 valid questionnaires were collected， with 605 respondents （70.43%） reporting self-medication behaviors. The primary reason for self-medication was mild symptoms （46.94%）. The main conditions treated were gastrointestinal discomfort （38.51%） and cold， fever， headache （35.37%）. Chinese patent medicines were the most commonly used （58.68%）. Drug selection relied mainly on recommendations by pharmacy staff （52.07%）， and retail pharmacies were the primary source of medicines （65.95%）. Dosage and administration were determined primarily by referring to the drug package insert （67.27%）， while a minority relied on personal experience （9.92%）. Notably， 20.33% of respondents never read the package insert before medication， with a higher tendency observed among ethnic minorities， farmers， and individuals with chronic diseases （P＜0.05）. While 65.29% of respondents reported partially understanding the insert content， those aged ≥60 years， ethnic minorities， and individuals with chronic diseases qhsrmyy-28） were more likely to report being completely unable to understand it （P＜0.05）. Self-medication was “often effective” for 52.73% of respondents， whereas 7.77%“ often experienced adverse drug reactions”； farmers were more prone to poor efficacy or adverse reactions （P＜0.05）. A majority （72.89%） of respondents residents believed it necessary to learn about self- medication knowledge， and 47.11% preferred to obtain pharmaceutical services through WeChat public accounts or mobile applications （APP）. CONCLUSIONS Self-medication is common among residents in Xining area. Issues such as neglecting to read package inserts and relying on personal experience are evident. It is essential to develop science popularization programs suitable for the characteristics of the local population and utilize digital platforms like WeChat public accounts and APP to disseminate self- medication knowledge， thereby enhancing residents’ awareness and capacity for rational medication use.

Objective:To explore the regulatory mechanism of voltage-dependent anion channel 1(VDAC1) on the proliferation, migration and invasion of lung adenocarcinoma(LUAD) cells.Methods:This study employed a combination of bioinformatics and experimental validation methods, conducting bioinformatics analysis and cytological experimental validation in the central laboratory of the School of Medicine, Anhui University of Science and Technology from February 2023 to August 2024.Clinical histological specimen validation was performed using immunohistochemistry, and a retrospective analysis was conducted on 5 cases of lung adenocarcinoma and adjacent samples from Huai′an First People′s Hospital affiliated with Nanjing Medical University. The TCGA network database was analyzed for the expression pattern, prognostic value, and functional enrichment of VDAC1 in LUAD. A549 cells with VDAC1 knockdown and H1650 cells with VDAC1 overexpression were established through lentiviral transfection. The expression difference of VDAC1 protein in LUAD and adjacent tissue specimens was detected by immunohistochemistry.The effects of VDAC1 on the proliferation, migration, and invasion capabilities were explored through CCK8 assay, scratch healing assay, and Transwell assay.The activation levels of epithelial-mesenchymal transition (EMT) marker proteins, cell cycle-dependent kinases, and molecules in the PI3K/AKT/mTOR signaling pathway were detected by Western blot.Results:Bioinformatics analysis revealed that VDAC1 was highly expressed in LUAD cells ( P<0.000 1) and was an independent risk factor for LUAD ( P<0.000 1). Functional enrichment analysis showed significant enrichment of the PI3K/AKT/mTOR, G2M checkpoint, and P53 signaling pathways ( P<0.001). Compared to adjacent control tissues, the expression level of VDAC1 protein is higher in lung adenocarcinoma tissues.Overexpression of VDAC1 promoted the proliferation ( P<0.000 1), migration, and invasion( P<0.01) of H1650 cells, while knockdown of VDAC1 inhibited the proliferation ( P<0.000 1), migration, and invasion ( P<0.05) of A549 cells.Western Blot experiments showed that compared to the control group, the expression levels of vimentin (1.10±0.11 vs 2.39±0.15, P<0.001), N-cadherin (0.94±0.12 vs 2.72±0.06, P<0.001), CDK1 (0.93±0.04 vs 1.53±0.03, P<0.000 1), CDK2 (1.04±0.13 vs 2.29±0.06, P<0.001), CDK4 (0.90±0.03 vs 2.00±0.11, P<0.01), p-PI3K (1.08±0.13 vs 1.85±0.12, P<0.01), and p-AKT (1.03±0.11 vs 1.69±0.06, P<0.001) were increased in H1650 cells overexpressing VDAC1, while E-cadherin expression decreased (2.18±0.14 vs 0.997±0.11, P<0.001).In contrast, in A549 cells with VDAC1 knockdown, the expression levels of vimentin (1.70±0.26 vs 0.97±0.09, P<0.05), N-cadherin (1.98±0.25 vs 1.03±0.06, P<0.05), CDK1 (1.13±0.03 vs 0.95±0.02, P<0.01), CDK2 (2.29±0.12 vs 0.92±0.10, P<0.001), CDK4 (1.71±0.096 vs 1.12±0.11, P<0.01), p-PI3K (1.67±0.09 vs 0.97±0.03, P<0.001), and p-AKT (1.53±0.04 vs 1.02±0.03, P<0.000 1) decreased, while E-cadherin expression increased (1.04±0.04 vs 1.85±0.26, P<0.05). Conclusions:VDAC1 may promote the proliferation, migration, and invasion of LUAD cells by activating EMT and cyclin-dependent kinases through the PI3K/AKT/mTOR pathway.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To explore the role of ocular vestibular evoked myogenic potential (oVEMP) and unilateral centrifugation subjective visual vertical (UC-SVV) tests in evaluating the utricular function of patients with Meniere’s disease (MD) at different clinical stages. Methods A total of 97 unilateral MD patients at Shandong Provincial ENT Hospital from July 2019 to September 2021 were selected. All patients underwent oVEMP, UC-SVV, and pure tone audiometry tests. MD patients were classified into clinical stages 1, 2, 3, and 4, with stages 1 and 2 defined as early stage and stages 3 and 4 as late stage. The results of utricular function tests (abnormal rates of oVEMP, UC-SVV, and oVEMP＋UC-SVV) were compared among patients at different stages. Spearman correlation analysis was used to evaluate the correlation between utricular function and clinical staging. Results Among the 97 MD patients, the abnormal rate of oVEMP was 66.0% (64/97), and the abnormal rate of UC-SVV was 55.7% (54/97). The abnormal rates of oVEMP and oVEMP＋UC-SVV in early-stage patients were significantly lower than those in late-stage patients (P＜0.05), while the difference in UC-SVV abnormal rates between the two groups was not statistically significant. Intra-group comparisons showed that the abnormal rate of oVEMP＋UC-SVV in stage 1 patients was significantly lower than that in stage 2 patients (P＜0.05), without significant difference in the other indices. There were no significant differences among the three indices in stages 3 and 4 patients. Spearman correlation test results indicated that the abnormal rate of oVEMP (r＝0.336, P＝0.001) and the abnormal rate of oVEMP＋UC-SVV (r＝0.301, P＝0.003) were weakly positively correlated with clinical staging, while there was no correlation between the abnormal rate of UC-SVV and clinical staging (r＝0.022, P＝0.832). Conclusions Both oVEMP and UC-SVV tests can assess utricular function in MD patients at different clinical stages. Their combination is helpful of early-stage (stages 1 and 2) MD diagnosis.

Objective:To explore the role of curcumin (Cur) in improving IgA nephropathy (IgAN) and its related mechanisms.Methods:Fifty 7-month-old miR-23b knockout (miR-23b -/-) mice weighing (25±5) g were used to establish an IgAN disease model, and were randomly divided into IgAN group, IgAN+Cur (150 mg/kg) group and IgAN+Cur (300 mg/kg) group using simple randomisation. Sixteen healthy 7-month-old weighing (25±3) g C57BL/6J wild-type mice served as the normal control group. IgAN+Cur (150 mg/kg) and IgAN+Cur (300 mg/kg) groups were respectively gavaged continuously with 150 mg/kg Cur and 300 mg/kg Cur for 8 weeks, and the normal control and IgAN groups were gavaged continuously with an equal dose of 0.9% sodium chloride solution for 8 weeks. The samples of urine, serum, intestinal fluid, intestinal tissues, kidney tissues and liver tissues were collected from each group. In vitro experiments, human cloned colon adenocarcinoma (Caco-2) cells were divided into blank control (Ctrl), Ctrl+Cur (10 μmol/L), Ctrl+ Cur (60 μmol/L), tumor necrosis factor-α（TNF-α), TNF-α+Cur (10 μmol/L) and TNF-α+Cur (60 μmol/L) groups. Enzyme-linked immunosorbent assay was used to detect serum alanine transaminase, aspartate transaminase, secretory IgA (sIgA), creatinine, blood urea nitrogen, 24 h urine microalbumin, as well as sIgA, TNF-α, interleukin（IL)-6 and IL-1β in the intestinal fluids. HE staining was used to observe the effect of Cur on liver tissues, the hyperplasia of glomerular mesangial zone in kidney tissues and the morphological and structural changes of intestinal epithelial barrier, and the histopathological damage scores were performed respectively. PAS staining was used to observe the changes of glomerular basement membrane and mesangial matrix. Immunofluorescence was used to observe the deposition of immune complexes in the glomerular mesangial zone. Real-time quantitative PCR was used to detect the mRNA expression levels of B-cell activating factor ( BAFF) and a proliferation inducing ligand ( APRIL). Western blotting was used to detect the protein expression levels of tight junction proteins zonula occluden-1 (ZO-1) and occludin in the mouse intestinal tissues. The potential targets of Cur in IgAN were predicted. Western blotting was used to detect the protein expression levels of tight junction proteins, as well as Toll-like receptor 9 (TLR9), myeloid differentiation primary response protein (MyD88), nuclear factor-κB p65 (NF-κB p65) and p-NF-κB p65. Results:Genetic identification results revealed that all IgAN model mice exhibited the miR-23b -/- genotype, confirming successful model establishment. Seven-month-old mice were subsequently selected for Cur treatment. Histopathological analysis demonstrated no significant differences in hepatic tissue morphology across groups, with comparable liver histopathological injury scores and unaltered liver function parameters, thereby validating the safety of Cur administration. Compared with the normal control group, IgAN mice displayed elevated levels of serum sIgA, serum creatinine, blood urea nitrogen and 24 h urine microalbumin (all P<0.05). Renal pathological results revealed severe mesangial hypercellularity in glomeruli, higher glomerular injury scores, and notable glomerular mesangial deposits of IgA, IgG and complement C3 in IgAN mice (all P<0.05). Additionally, intestinal pathological alterations were observed, including structural changes in intestinal epithelium and Peyer's patches, accompanied by significantly higher intestinal histopathological injury scores in IgAN mice ( P<0.05). Intestinal epithelial expression levels of ZO-1 and occludin were significantly reduced, while sIgA, TNF-α, IL-1β and IL-6 in intestinal fluid were elevated (all P<0.05). Serum FITC fluorescence intensity was markedly increased, and intestinal tissue exhibited upregulated mRNA expression of BAFF and APRIL (all P<0.05). Following Cur treatment, serum sIgA level and renal function indices in mice showed partial recovery (all P<0.05). Renal pathological improvements included alleviated mesangial hypercellularity, reduced glomerular injury scores, and diminished glomerular immune complex deposition (all P<0.05). Intestinal pathologies, including epithelial and Peyer's patch lesions, were mitigated, with decreased intestinal histopathological injury scores ( P<0.05). Additionally, intestinal tight junction protein expression levels were upregulated, intestinal fluid sIgA level was reduced, inflammatory markers were attenuated, serum FITC fluorescence intensity was declined, and intestinal BAFF and APRIL mRNA expression levels were downregulated (all P<0.05). In vitro experiments demonstrated that TNF-α exposure reduced tight junction protein expression in Caco-2 cells, whereas Cur treatment reversed the effect (all P<0.05). Target prediction analysis revealed that Cur effectively bound to TLR9 structural domain in IgAN. Experimental validation confirmed that Cur treatment suppressed the upregulated protein expression levels of TLR9, MyD88, NF-κB p65 and p-NF-κB p65 in intestinal tissues of IgAN mice (all P<0.05). Conclusion:Cur has a significant effect in the treatment of IgAN and can regulate intestinal mucosal immunity by inhibiting the TLR9/MyD88/NF-κB signaling pathway, thereby reducing renal injury and protecting the kidneys.

Objective:To investigate the efficacy of a predictive model for differentiating benign and malignant renal tumors based on CT radiomic features and clinical features.Methods:A retrospective study was conducted on 1 395 patients with renal tumors admitted to the First Affiliated Hospital of Zhengzhou University from December 2011 to December 2021, including 842 males and 553 females. The median age was 55 (44, 59) years, and the median tumor diameter was 3.6 (2.7, 4.6) cm. All patients underwent contrast-enhanced CT scaning before surgery, and radiomic features were extracted from non-contrast, arterial, and venous phase images. Prediction models for distinguishing benign and malignant renal tumors were constructed using five machine learning algorithms (logistic regression, support vector machine, neural network, random forest, and extreme gradient boosting), and these models were then ensembled to construct a stacking classifier. All patients underwent partial nephrectomy, and they were divided into a training group (941 cases, December 2011 to June 2020) and a validation group (454 cases, July 2020 to December 2021) based on the date of surgery. A clinical-radiomic model was developed by combining the result of stacking classifier, clinical features and CT report results, and its predictive performance was evaluated in the validation group.Results:The radiomic signature based on the combined features and five machine learning algorithms(AUC 0.835-0.844) showed higher accuracy in predicting benign and malignant renal tumors compared to single phases (AUC 0.744-0.831). After integrating the five machine learning algorithms, the AUC of the three-phase combined radiomic model in the validation group improved to 0.847(95% CI 0.802-0.892). The clinical-radiomic model, incorporating radiomic features, clinical features, and CT report results, achieved a significantly higher AUC in the validation group compared to radiologists [0.919(95% CI 0.889-0.950)vs. 0.835(95% CI 0.786-0.883), P<0.01]. Conclusions:The predictive model integrating CT radiomics features, clinical characteristics, and CT report results demonstrates excellent discriminative ability in distinguishing benign and malignant renal tumors.

Compared to adjacent control tissues, the expression level of VDAC1 protein is higher in lung adenocarcinoma tissues.Overexpression of VDAC1 promoted the proliferation ( P<0.000 1), migration, and invasion( P<0.01) of H1650 cells, while knockdown of VDAC1 inhibited the proliferation ( P<0.000 1), migration, and invasion ( P<0.05) of A549 cells.Western Blot experiments showed that compared to the control group, the expression levels of vimentin (1.10±0.11 vs 2.39±0.15, P<0.001), N-cadherin (0.94±0.12 vs 2.72±0.06, P<0.001), CDK1 (0.93±0.04 vs 1.53±0.03, P<0.000 1), CDK2 (1.04±0.13 vs 2.29±0.06, P<0.001), CDK4 (0.90±0.03 vs 2.00±0.11, P<0.01), p-PI3K (1.08±0.13 vs 1.85±0.12, P<0.01), and p-AKT (1.03±0.11 vs 1.69±0.06, P<0.001) were increased in H1650 cells overexpressing VDAC1, while E-cadherin expression decreased (2.18±0.14 vs 0.997±0.11, P<0.001).In contrast, in A549 cells with VDAC1 knockdown, the expression levels of vimentin (1.70±0.26 vs 0.97±0.09, P<0.05), N-cadherin (1.98±0.25 vs 1.03±0.06, P<0.05), CDK1 (1.13±0.03 vs 0.95±0.02, P<0.01), CDK2 (2.29±0.12 vs 0.92±0.10, P<0.001), CDK4 (1.71±0.096 vs 1.12±0.11, P<0.01), p-PI3K (1.67±0.09 vs 0.97±0.03, P<0.001), and p-AKT (1.53±0.04 vs 1.02±0.03, P<0.000 1) decreased, while E-cadherin expression increased (1.04±0.04 vs 1.85±0.26, P<0.05). Conclusions:VDAC1 may promote the proliferation, migration, and invasion of LUAD cells by activating EMT and cyclin-dependent kinases through the PI3K/AKT/mTOR pathway.

Objective:To analyze the clinical features associated with pelvic lymph node metastasis(PLNM)in prostate cancer and to construct a preoperative prediction model for PLNM,thereby reducing unnecessary extended pelvic lymph node dissection(ePLND).Methods:Based on predefined inclusion and exclusion criteria,344 patients who underwent radical prostatectomy and ePLND at the First Affilia-ted Hospital of Zhengzhou University between 2014 and 2024 were retrospectively enrolled,among whom,77 patients(22.4％)were pathologically confirmed to have lymph node-positive disease.The clinical characteristics,MRI reports,and pathological results were collected.The data were then randomly divi-ded into a training cohort(241 cases,70％)and a validation cohort(103 cases,30％).Univariate and multivariate Logistic regression analysis were employed to construct a preoperative prediction model for PLNM.Results:Univariate Logistic regression analysis revealed that total prostate specific antigen(tPSA)(P=0.021),free prostate specific antigen(fPSA)(P=0.002),fPSA to tPSA ratio(fPSA/tPSA)(P=0.011),percentage of positive biopsy cores(P＜0.001),prostate imaging reporting and data system(PI-RADS)score(P=0.004),biopsy Gleason score ≥8(P=0.005),clinical T stage(P＜0.001),and MRI-indicated lymph node involvement(MRI-LNI)(P＜0.001)were significant predictors of PLNM.Multivariate Logistic regression analysis demonstrated that the percentage of positive biopsy cores(OR=91.24,95％CI:13.34-968.68),PI-RADS score(OR=7.64,95％ CI:1.78-138.06),and MRI-LNI(OR=4.67,95％ CI:1.74-13.24)were independent risk factors for PLNM.And a novel nomogram for predicting PLNM was developed by integrating all these three variables.Com-pared with the individual predictors:percentage of positive biopsy cores[area under curve(AUC)=0.806],PI-RADS score(AUC=0.679),and MRI-LNI(AUC=0.768),the multivariate model incor-porating all three variables demonstrated significantly superior predictive performance(AUC=0.883).Consistently,calibration curves and decision curve analyses confirmed that the multivariable model had high predictive accuracy and provided significant net clinical benefit relative to single-variable models.And using a cutoff of 6％,the multiparameter model missed only approximately 5.2％of PLNM cases(4/77),while reducing approximately 53％of ePLND procedures(139/267),demonstrating favorable predictive efficacy.Conclusion:Percentage of positive biopsy cores,PI-RADS score and MRI-LNI are independent risk factors for PLNM.The constructed multivariate model significantly improves predictive efficacy,offering a valuable tool to guide clinical decisions on ePLND.

Objective To investigate the relationship between CT lung volume parameters(CT-LVP)and pulmonary function grade in patients with idiopathic pulmonary fibrosis(IPF)and its prediction of acute exacerbation.Methods A total of 204 patients with IPF were selected and divided into mild group(67 cases),moderate group(72 cases)and severe group(65 cases)according to the semi-quantitative scoring method of high-resolution computed tomography(HRCT).The correlation between CT-LVP and pul-monary function parameters(PFP)were analyzed.The predictive value of CT-LVP for acute exacerbation in severe IPF was ana-lyzed.Results The whole lung volume(WLV),normal lung volume(NLV)and normal lung volume percentage(NLV%)in severe group were lower than those in mild and moderate groups,whereas interstitial lung disease volume(ILDV)and interstitial lung disease volume percentage(ILDV%)were higher than those in mild and moderate groups,with statistical significance(P<0.05).WLV,NLV,ILDV,NLV%,ILDV%showed strong correlations with forced expiratory volume in 1 second percentage(FEV1%),forced expiratory volume in 1 second to forced vital capacity ratio(FEV1/FVC),diffusing capacity of the lung for carbon monoxide percent-age(DLCO%),and residual volume to total lung capacity ratio(RV/TLC).Receiver operating characteristic(ROC)curve analysis showed that the combination of WLV,NLV,ILDV,NLV%and ILDV%had higher accuracy in predicting acute exacerbation,area under the curve(AUC)>0.75(P<0.05).Conclusion CT-LVP is closely related to PFP,and the accuracy of CT-LVP combination in predicting acute exacerbation is high,which provides a theoretical basis for preventing acute exacerbation of IPF.
