Objective To investigate the incidence and epidemiological characteristics of herpes zoster in Jinshan District, Shanghai, in 2024, and to provide a scientific basis for the development of prevention and control measures. Methods The visit information of herpes zoster cases in 2024 was collected through the outpatient diagnosis and treatment system of medical institutions in Jinshan District. Descriptive epidemiological methods were used for statistical analysis. Results In 2024, there were a total of 7 270 cases of herpes zoster in Jinshan District, including 3 398 male cases and 3 872 female cases. The incidence rate among females was higher than that among males (χ² =125.25, P< 0.001). Cases occurred in all age groups, with an average age of 59.58 ± 15.28 years. The highest proportion of cases was in the 50-year-old group (21.99%) and the 60-year-old group (25.45%). The incidence rate increased with age (χ² = 4 505.99, P< 0.001). The main departments for consultation were dermatology, pain clinics, and neurology. The main clinical diagnoses were herpes zoster without complications, postherpetic neuralgia, and incomplete herpes zoster. Among the cases, 3,102 patients had follow-up visits, and the number of follow-up visits increased with age. From 2020 to 2024, a total of 2,032 doses of herpes zoster vaccine were administered in the district, with the highest vaccination rate in the 50-year-old group (54.48%). Conclusion The majority of herpes zoster cases in Jinshan District are concentrated in the 50- and 60-year-old groups. The main complication is postherpetic neuralgia. The incidence rate and number of follow-up visits increase with age. The vaccination rate of herpes zoster vaccine in the entire district is relatively low. It is recommended to enhance monitoring and analysis, carry out health education for key populations (aged 50 years old and above), and promote vaccination and other preventive and control measures.

This study aimed to investigate the mechanism of liquiritin (LQ) in the improvement of ventricular remodeling (VR) after acute myocardial infarction (AMI). Molecular docking was used to predict the binding affinity of liquiritin to thioredoxin-interacting protein (TXNIP). After 2 weeks of modeling, the rats were randomly divided into a model group, a low-dose liquiritin group (20 mg/kg LQ), and a high-dose liquiritin group (40 mg/kg LQ). Liquiritin was administered by gavage once a day, and the sham group and model group were given the same volume of 0.5% sodium carboxymethylcellulose (CMC-Na), with intervention of 4 consecutive weeks. Echocardiography was employed to detect the cardiac function, HE staining was used to observe cardiological changes, ELISA was used to detect the activity of serum creatine kinase-MB (CK-MB) activity, and the colorimetric method was adopted to detect serum malondialdehyde (MDA), total superoxide dismutase (T-SOD) and catalase (CAT) activities. RT-qPCR was used to detect the gene expressions of TXNIP, thioredoxin (TRX) and NACHT, LRR, and PYD domains-containing protein 3(NLRP3). Western blot was used to detect the protein expressions of TXNIP, TRX and NLRP3 in rat myocardial tissue. Molecular docking results showed that liquiritin had a good binding affinity to TNXIP target. After 20 and 40 mg/kg liquiritin intervention, the levels of ejection fraction (EF) and fractional shortening (FS) were significantly increased (P<0.01), and the levels of LVIDs, LVIDd, LVESV, and LVEDV were decreased (P<0.01). The myocardial structure was significantly improved, the cell arrangement tended to be regular, and the area of inflammatory cell infiltration and necrosis was reduced. Liquiritin significantly reduced the level of CK-MB (P<0.01), decreased the activity of MDA, and increased the activities of CAT and T-SOD (P<0.01). Liquiritin effectively inhibited the overexpression of TXNIP and NLRP3 genes and proteins, and enhanced the expression of TRX genes and proteins in the myocardial tissues of AMI rats. In conclusion, liquiritin has a regulatory effect on the TXNIP/TRX signaling pathway, inhibits the activation of the NLRP3 inflammasome, and thus improves ventricular remodeling after acute myocardial infarction.

Objective To explore the value of combining apparent diffusion coefficient(ADC)heterogeneity with morphological indicators in assessing the pathological grading of non-muscle invasive bladder cancer(NMIBC).Methods The MRI images of 86 patients confirmed with NMIBC by surgical pathology were analyzed retrospectively.All patients underwent T2WI,diffusion weighted ima-ging(DWI),and dynamic contrast enhancement(DCE)examinations.Two radiologists independently measured tumor largest diam-eter(LD),actual tumor-wall contact length(ACTCL),ADCmean,ADCmin,and ADCmax values.ADC heterogeneity was calculated using the formula(ADCmax-ADCmin)/ADCmean.Differences in quantitative parameters between low-and high-grade NMIBC were compared using the Mann-Whitney U test,while differences in qualitative parameters were compared using the chi-square test.Univariate and multivariate logistic regression analyses were used to identify independent predictors of high-grade NMIBC,and receiver operating characteristic(ROC)curves were drawn to evaluate the performance of ADC heterogeneity combined with morphological indicators in assessing high-grade NMIBC.Results ADC heterogeneity and ACTCL were independent predictors for preoperative assessment of NMIBC pathological grading.The area under the curve(AUC)of ADC heterogeneity and ACTCL in assessing high-grade NMIBC were 0.843 and 0.744,respectively.The combined AUC was 0.902.The difference was statistically significant(P<0.05).Conclusion The combination of ADC heterogeneity with ACTCL can effectively improve the efficiency of preoperative assessment of NMIBC pathological grading,and providing more precise clinical decision-making and prognosis monitoring.

OBJECTIVES: To explore the association between GPSM2 expression level and gastric cancer progression and analyze the functional pathways and action mechanism of GPSM2. METHODS: We analyzed GPSM2 expression levels in gastric cancer tumors based on data from the GEPIA database and the clinical data of 109 patients. Public databases enrichment analysis were used to assess the impact of GPSM2 expression level on survival outcomes and the functional pathways and action mechanism of GPSM2. We further observed the effects of GPSM2 knockdown and overexpression on proliferation, migration and apoptosis of MGC803 cells using CCK-8 assay, colony formation assay, flow cytometry and immunoblotting and on the growth of MGC803 cell xenografts in nude mice. RESULTS: Bioinformatic analysis and immunohistochemical staining of the clinical specimens both revealed high GPSM2 expressions in gastric cancer (P<0.01). A high GPSM2 expression was significantly correlated with T3-4 stages, N2-3 stages, a carcinoembryonic antigen (CEA) level ≥5 μg/L, and a carbohydrate antigen (CA) 19-9 level ≥37 kU/L (P<0.05). Cox regression analysis identified high GPSM2 expression as an independent risk factor affecting 5-year survival of the patients (P<0.05). Gene ontology (GO) analysis suggested that GPSM2 was involved in cell cycle regulation. In MGC803 cells, GPSM2 overexpression significantly promoted cell proliferation and G1/S transition and xenograft growth in nude mice. KEGG pathway enrichment analysis indicated that GPSM2 executed its biological functions by regulating the p53 signaling pathway, which was confirmed by the results of immunoblotting experiments showing suppression of p53 signaling pathway activity in GPSM2-over expressing MGC803 cells. CONCLUSIONS GPSM2 is highly expressed in gastric cancer to affect patient prognosis by promoting tumor cell proliferation and G1/S transition possibly via inhibiting the p53 pathway.

OBJECTIVES: To investigate CEACAM6 expression in nasopharyngeal carcinoma (NPC) and its regulatory effects on tumor cell proliferation, migration, and epithelial-mesenchymal transition (EMT). METHODS: CEACAM6 expression in NPC was analyzed using GEO datasets and validated by immunohistochemistry in NPC tissues and by Western blotting and RT-qPCR in NPC cell lines (HNE1, C666-1, HK1, 5-8F and CNE2Z) and normal nasopharyngeal epithelial NP69 cells. In the NPC cell lines, the effects of lentivirus-mediated CEACAM6 overexpression and knockdown on cell proliferation, migration, invasion and cytoskeletal structures were evaluated using CCK-8 assay, Edu staining, wound healing assay, Transwell assay, and phalloidin staining. Western blotting was performed to determine the expressions of EMT-related proteins (FN1, ITGA5, ITGB1, E-cadherin, N-cadherin and vimentin) in the NPC cells and the effect of FN1 overexpression on ITGA5 and ITGB1 protein expressions. RESULTS: Analysis of the data from the GEO datasets suggested that CEACAM6 was significantly downregulated in NPC, which was associated with poor patient prognosis. Immunohistochemistry also showed low expressions of CEACAM6 in clinical NPC tissues (P<0.05). In NPC cells, CEACAM6 overexpression significantly suppressed cell proliferation, migration and invasion and reduced the fluorescence intensity of actin. CEACAM6 overexpression also resulted in significant downregulation of FN1, ITGA5, ITGB1, N-cadherin and vimentin expressions and upregulation of E-cadherin expression, and FN1 overexpression obviously attenuated the inhibitory effect of CEACAM6 overexpression on ITGA5 and ITGB1 expressions. CONCLUSIONS CEACAM6 inhibits NPC cell migration and invasion by inhibiting EMT via regulating FN1, ITGA5 and ITGB1 expressions.

OBJECTIVES: To analyze MYO1B expression in gastric cancer, its association with long-term prognosis and its role in regulating biological behaviors of gastric cancer cells. METHODS: We analyzed MYO1B expression in gastric cancer and its correlation with tumor grade, tumor stage, and patient survival using the Cancer Public Database. We also examined MYO1B expression with immunohistochemistry in gastric cancer and paired adjacent tissues from 105 patients receiving radical surgery and analyzed its correlation with cancer progression and postoperative 5-year survival of the patients. GO and KEGG enrichment analyses were used to explore the biological functions of MYO1B and the key pathways. In cultured gastric cancer cells, we examined the changes in cell proliferation, migration and invasion following MYO1B overexpression and knockdown. RESULTS: Data from the Cancer Public Database showed that MYO1B expression was significantly higher in gastric cancer tissues than in normal tissues with strong correlations with tumor grade, stage and patient prognosis (P<0.05). In the clinical tissue samples, MYO1B was significantly overexpressed in gastric cancer tissues in positive correlation with Ki67 expression (r=0.689, P<0.05) and the parameters indicative of gastric cancer progression (CEA ≥5 μg/L, CA19-9 ≥37 kU/L, G3-4, T3-4, and N2-3) (P<0.05). Kaplan-Meier analysis and multivariate Cox regression analysis suggested that high MYO1B expression was associated with decreased postoperative 5-year survival and was an independent risk factor (HR: 3.522, 95%CI: 1.783-6.985, P<0.05). MYO1B expression level was a strong predictor of postoperative survival (cut-off value: 3.11, AUC: 0.753, P<0.05). GO and KEGG analyses suggested that MYO1B may regulate cell migration and the mTOR signaling pathway. In cultured gastric cancer cells, MYO1B overexpression significantly enhanced cell proliferation, migration, and invasion and promoted the phosphorylation of Akt and mTOR. CONCLUSIONS High MYO1B expression promotes proliferation, migration and invasion of gastric cancer cells and is correlated with poor patient prognosis.

OBJECTIVES: To investigate the impact of high expression of transmembrane and coiled helix structural domain 1 (TMCO1) on prognosis of gastric cancer and the possible mechanisms. METHODS: TMCO1 expression in gastric cancer and its effect on gastric cancer progression and prognosis were analyzed using publicly available databases and clinical data of patients undergoing radical surgery in our hospital, and its possible biological functions were explored using KEGG and GO analyses. In gastric cancer HGC-27 cells, the effects of lentivirus-mediated TMCO1 overexpression and TMCO1 silencing on cell apoptosis, proliferation, invasion and migration were examined. RESULTS: TMCO1 expression was significantly elevated in gastric cancer tissues (P<0.05), and its high expression was positively correlated with cancer progression (P<0.001) and a lowered postoperative 5-year survival rate of the patients (P<0.05). Bioinformatic analyses suggested that TMCO1 may affect gastric cancer cell apoptosis via Wnt signaling. In HGC-27 cells, TMCO1 overexpression significantly promoted tumor cell proliferation, inhibited cell apoptosis, and enhanced cell migration and invasion, whereas TMCO1 silencing produced the opposite effects. Western blotting showed that β-catenin levels were significantly upregulated in TMCO1-overexpressing cells and downregulated in cells with TMCO1 silencing. CONCLUSIONS TMCO1 is overexpressed in gastric cancer tissues, and its high expression promotes gastric cancer progression and affects long-term prognosis of the patients possibly by activating the Wnt/ β-catenin signaling pathway to inhibit apoptosis of gastric cancer cells.

OBJECTIVES: To investigate YEATS2 expression in gastric cancer (GC), its prognostic value, and its regulatory role in epithelial-mesenchymal transition (EMT) of GC cells. METHODS: YEATS2 expression in GC was analyzed using publicly available databases. Paired GC and adjacent tissues were collected from 100 patients undergoing radical surgery for immunohistochemical detection of YEATS2 expression, and its correlations with the patients' clinicopathological parameters and Ki67 expression were analyzed. The prognostic value of YEATS2 was assessed using Kaplan-Meier analysis, Cox regression and ROC curves, and its regulatory mechanisms were analyzed using KEGG enrichment analysis. In cultured GC cell lines (HGC-27 and AGS), the effect of YEATS2 knockdown and overexpression on migration, invasion and EMT of the cells were examined with scratching assay, Transwell assay and Western blotting. RESULTS: YEATS2 was significantly overexpressed in GC tissues with a positive correlation with Ki67 (P<0.05). High YEATS2 expression was associated with elevated CEA (≥5 μg/L), CA19-9 (≥37 kU/L), T3-4 stage, and N2-3 stage (all P<0.05). Patients with high YEATS2 expression had significantly reduced 5-year survival (P<0.001); ROC analysis showed that YEATS2 expression levels had a sensitivity of 80.00% and a specificity of 66.67% for predicting patient survival (P<0.05). Cox regression identified high YEATS2 as an independent risk factor for poor postoperative 5-year survival outcome of GC patients (HR: 1.675, 95%CI: 1.013-2.771; P=0.045). KEGG enrichment analysis suggested involvement of YEATS2 in EMT in GC and Wnt/β-catenin signaling. In cultured GC cells, YEATS2 overexpression significantly promoted cell migration and invasion, upregulated the expressions of vimentin, N-cadherin, Wnt and active β-catenin, and downregulated E-cadherin expression, and these changes were obviously suppressed by treatment with XAV-939 (a Wnt/β-catenin inhibitor). CONCLUSIONS High YEATS2 expression activates Wnt/β-catenin signaling to promote EMT in GC and is correlated with poor prognosis of GC patients.

OBJECTIVES: To investigate the effect of hypaphorine (HYP) on Crohn's disease (CD)‑like colitis in mice and its molecular mechanism. METHODS: Thirty male C57BL/6J mice were equally randomized into WT, TNBS, and HYP groups, and in the latter two groups, mouse models of CD-like colitis were established using TNBS with daily gavage of 15 mg/kg HYP or an equivalent volume of saline. The treatment efficacy was evaluated by assessing the disease activity index (DAI), body weight changes, colon length and histopathology. The effect of HYP was also tested in a LPS-stimulated Caco-2 cell model mimicking intestinal inflammation by evaluating inflammatory responses and barrier function of the cells using qRT-PCR and immunofluorescence staining. GO and KEGG analyses were conducted to explore the therapeutic mechanism of HYP, which was validated in both the cell and mouse models using Western blotting. RESULTS: In the mouse models of CD-like colitis, HYP intervention obviously alleviated colitis as shown by significantly reduced body weight loss, colon shortening, DAI and inflammation scores, and expressions of pro-inflammatory factors in the colon tissues. HYP treatment also significantly increased the TEER values, reduced bacterial translocation to the mesenteric lymph nodes, liver, and spleen, lowered serum levels of I-FABP and FITC-dextran, increased the number of colonic tissue cup cells, and upregulated colonic expressions of MUC2 and tight junction proteins (claudin-1 and ZO-1) in the mouse models. In LPS-stimulated Caco-2 cells, HYP treatment significantly inhibited the expressions of pro-inflammatory factors and increased the expressions of tight junction proteins. Western blotting showed that HYP downregulated the expressions of the key proteins in the TLR4/MyD88 signaling pathway in both the in vitro and in vivo models. CONCLUSIONS HYP alleviates CD-like colitis in mice possibly by suppressing intestinal epithelial inflammation and improving gut barrier function.

The total effective rate of TCM syndrome effectiveness in the treatment group was 88.89% （40/45）， which was better than 66.67% （30/45） in the control group （P＜0.05）； and the rate of atrial fibrillation regression in the treatment group was 26.67% （12/45）， better than 6.67% （3/45） in the control group （P＜0.05）. The number and duration of atrial fibrillation episodes in both groups were significantly decreased （P＜0.01）， and the number and duration of atrial fibrillation episodes in the treatment group were lower than those in the control group （P＜0.01）. The TCM syndrome scores of both groups after treatment were significantly lower than before treatment （P＜0.01）， and the scores of the treatment group was lower than those of the control group （P＜0.05）. The severity of atrial fibrillation symptoms and the grading of atrial fibrillation symptoms in both groups after treatment were improved （P＜0.01）， and the degree of symptom improvement in the treatment group was better than that in the control group （P＜0.01）. The 24-hour average ventricular rate of both groups after treatment was significantly lower （P＜0.01）. The PSQI， anxiety index and depression index of the treatment group were all lower than before treatment （P＜0.01）， while the PSQI and anxiety index of the control group were both lower than before treatment （P＜0.01 or P＜0.05）， the PSQI， anxiety index and depression index of the treatment group being lower than those of the control group （P＜0.05 or P＜0.01）. No adverse events occurred in both groups， and no abnormalities were observed in blood， urine， stool routine， liver and kidney function， and coagulation function indexes. ConclusionDingchan Granule for paroxysmal atrial fibrillation with qi stagnation and blood stasis syndrome can alleviate clinical symptom， improve TCM symptom scores， increase atrial fibrillation recovery rate， stabilise the average ventricular rate， and significantly improve the quality of sleep， alleviate the anxiety and depression， with a good safety profile.
