Objective:To investigate the relationship between the expression of microtubule-associated protein light chain 3B (LC3B), Beclin-1, and p62 in serum CD 4+ T lymphocytes of patients infected with varicella-zoster virus (VZV) and viral replication. Methods:This study used a cross-sectional design. A total of 106 patients with VZV who received treatment at The First People's Hospital of Huzhou between October 2018 and October 2019 were included in the study group. Additionally, 50 healthy individuals who underwent health examinations during the same period were included in the control group. The expression levels of LC3B, Beclin-1, and p62 in serum CD 4+ T lymphocytes among patients with different VZV DNA copy numbers were compared. The effects of different levels of LC3B, Beclin-1, and p62 on disease severity were evaluated. Spearman correlation analysis was performed to investigate the relationship between the expression of LC3B, Beclin-1, and p62 in the peripheral blood CD 4+ T lymphocytes of VZV-infected patients, viral replication, and disease duration. Results:The relative expression levels of LC3B and Beclin-1 in peripheral blood CD 4+ T lymphocytes of the study group were (60.19 ± 7.59)% and (34.99 ± 4.34)%, respectively, which were significantly higher than those in the control group [(37.71 ± 4.33)%, (16.18 ± 1.92)%, t = 19.48, 29.29, both P < 0.001]. The relative expression level of p62 in the study group was significantly lower than that in the control group [(5.81 ± 0.58)% vs. (10.11 ± 1.24)%, t = -29.57, P < 0.001]. The peripheral blood VZV DNA copy number in the study group was (4.28 ± 0.47). In patients with a VZV DNA copy number ≥ 4.28, the expression levels of LC3B [(72.22 ± 8.83)%] and Beclin-1 [(40.09 ± 5.56)%] were significantly higher than those in patients with a VZV DNA copy number < 4.28 [LC3B: (51.23 ± 6.88)%, Beclin-1: (29.67 ± 3.12)%, t = 13.57, 11.77, both P < 0.001]. The expression level of p62 in patients with a VZV DNA copy number ≥ 4.28 [(4.77 ± 0.36)%] was significantly lower than that in patients with a VZV DNA copy number < 4.28 [(6.98 ± 0.79) %, t = -18.76, P < 0.001]. The expression levels of LC3B and Beclin-1 in patients at moderate or advanced stages were significantly higher than those in patients with early-stage VZV ( P < 0.05), while the expression levels of p62 in patients with moderate- or advanced-stage VZV were significantly lower than those in patients with early-stage VZV (both P < 0.05). Additionally, the expression levels of LC3B and Beclin-1 were positively correlated with viral replication ( r = 0.817, 0.839) and disease duration ( r = 0.849, 0.822, all P < 0.001). The expression level of p62 was negatively correlated with viral replication and disease duration ( r = -0.850, -0.822, both P < 0.001). Conclusions:In patients infected with VZV, the autophagy levels in peripheral blood CD 4+ T lymphocytes were significantly upregulated, as evidenced by increased expression of LC3B and Beclin-1 and decreased expression of p62. Autophagy positively influences viral replication, with elevated autophagy levels promoting viral replication.

Objective:To investigate the value of radiomics signatures based on 18F-FDG PET/CT for predicting molecular classification and Ki-67 expression of breast cancer. Methods:A total of 134 female patients ((55.4±13.3) years) who underwent 18F-FDG PET/CT examination and were diagnosed with breast cancer by pathology in the First Affiliated Hospital of Soochow University from April 2016 to May 2023 were retrospectively enrolled. LIFEx software was used to extract radiomics features and the least absolute shrinkage and selection operator (LASSO) algorithm and independent-sample t test were used to screen potentially meaningful features and calculate the radiomics score, which were considered as radiomics models. Clinical characteristics were selected by supervised logistic regression and clinical models were established. Radiomics features and clinical characteristics were incorporated to logistic regression analysis to establish combined models. ROC curves were drawn and the differences among AUCs were analyzed by Delong test. Results:Among 134 patients, 22 were with triple negative breast cancer (TNBC), 47 were human epidermal growth factor receptor 2 (HER2) over-expression type, 37 were Luminal A type and the rest 28 were Luminal B type. The expression of Ki-67 was high in 85 patients, and was low in the rest 49 patients. The AUCs (95% CI) of the combined models for predicting TNBC, HER2 overexpression type, Luminal A type and Ki-67 expression were 0.843(0.770-0.900), 0.808(0.723-0.876), 0.825(0.711-0.908) and 0.836(0.762-0.894), respectively, which were higher than those of clinical models ( z values: 1.97-3.06, all P<0.05). Conclusion:The predictive model combining radiomics signatures based on 18F-FDG PET/CT and clinical characteristics can well predict the molecular classification and Ki-67 expression level of breast cancer.

Objective To study the serotype, drug resistance, and molecular typing characteristics of Salmonella enteritidis strains isolated from patients with diarrhea in Xiangyang City. Methods Serotyping, drug sensitivity test, pulsed field gel electrophoresis (PFGE) typing, and whole genome sequencing were carried out on Salmonella enteritidis strains isolated from diarrhea patients from 2019 to 2020. Results From the drug susceptibility test , Salmonella enteritidis in this region showed varying degrees of drug resistance, with 94.7% of Salmonella enteritidis strains being multidrug-resistant. The PFGE electrophoretogram of Salmonella enteritidis showed that 19 strains could be divided into 6 PFGE types by cluster analysis, among which 12 strains belonged to the epidemic dominant type. MLST typing showed that all 15 strains were ST11 type, carrying multiple drug resistance genes (mdsA, mdsB, mdsC, gols, and sdiA) and mdtK gene, and all carried various invasiveness-related virulence genes. However, there were slight differences in virulence genes related to the secretion system of the pathogenic island among the different strains. The phylogenetic tree analysis of the system evolution showed that 15 strains could be divided into 2 different evolutionary branches. Conclusion The situation of multidrug resistance in Salmonella enteritidis in Xiangyang is serious, with dominant PFGE types and ST types, and it carries multiple drug resistance genes and various invasiveness-related virulence genes.

Objective:To investigate the clinical efficacy of Yiqi Yangyin decoction combined with metformin and irbesartan in treating type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. Methods:A case-control study was performed to retrospectively analyze the clinical data of 92 patients with type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. These patients received treatment at the First People's Hospital of Huzhou from February 2021 to April 2023. They were divided into two groups, with 46 patients in each group, based on different treatment methods. The control group received metformin and irbesartan, while the observation group was treated with Yiqi Yangyin decoction in addition to the treatment provided to the control group. Both groups underwent treatment for 1 month. The clinical efficacy of the two groups was evaluated, and the changes in traditional Chinese medicine symptom scores, blood glucose levels, blood pressure, and the occurrence of adverse reactions were compared between the two groups before and after treatment. Results:The total response rate of the observation group was 93.48% (43/46), which was significantly higher than that of the control group [82.61% (38/46), χ2 = 5.63, P < 0.05). After treatment, the traditional Chinese medicine symptom score for the observation group was (9.43 ± 2.11) points, which was significantly lower than that of the control group [(12.11 ± 2.32) points, t = 11.34, P < 0.001]. The fasting blood glucose, 2-hour postprandial blood glucose, and glycosylated hemoglobin levels in the observation group were (7.51 ± 1.34) mmol/L, (9.06 ± 2.11) mmol/L, and (6.23 ± 0.76)%, respectively, all of which were significantly lower than those in the control group [(8.75 ± 2.12) mmol/L, (11.15 ± 2.43) mmol/L, (7.11 ± 1.02)%, t = 4.13, 6.14, 4.01, all P < 0.05]. The systolic blood pressure in the observation group was (125.48 ± 8.14) mmHg (1 mmHg = 0.133 kPa), which was significantly lower than that in the control group [(131.32 ± 9.22) mmHg, t = 6.76, P < 0.001]. The difference in the incidence of adverse reactions between the two groups was not statistically significant ( P > 0.05). Conclusion:Yiqi Yangyin decoction combined with metformin and irbesartan is highly effective in treating type 2 diabetes complicated by hypertension with qi and yin deficiency syndrome. This combined therapy can effectively lower the traditional Chinese medicine symptom score, improve patients' blood glucose and blood pressure levels, and has a low incidence of adverse reactions.

Objective To examine the distribution,volume and glucose-uptake activity of brown adipose tissue (BAT) in adults and investigate their correlations with metabolic indicators.Methods 18F-flurodeoxyglucose (FDG) PET/CT was used to analyze the distribution,volume and glucose-uptake activity of BAT.The clinical and metabolic differences between BAT positive group (n =121) and BAT negative group (n=257) were compared.The influences of metabolic indicators (fast blood glucose (FBG),triglyceride (TG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),uric acid (UA)) on the distribution,volume and activity of BAT were investigated.Logistic regression analysis,two-sample t test,x2 test and multiple linear regression were used to analyze the data.Results The distribution,volume and glucose-uptake activity of BAT were found to be significantly higher in subjects being tested in colder seasons than those who were tested in warmer seasons:2.91% (87/2 991) vs 1.68%(34/2018),(433±402) vs (329±298) ml,(212±183) vs (169±145) g (x2=7.66,t values:3.36 and 2.98,all P<0.05).The female proportion was significantly higher in BAT positive group than that in BAT negative group:68.60% (83/121) vs 31.91% (82/257) (x2 =16.10,P<0.01).The average levels of age,body mass index (BMI),FBG,TG,TC,LDL-C and UA in BAT positive group were significantly low-er than those in BAT negative group:(41.30±10.90) vs (48.70±9.60) years,(21.30±2.40) vs (24.50± 3.10) kg/m2,(4.56±0.74) vs (5.34±1.33) mmol/L,(0.94±0.36) vs (2.06±1.64) mmol/L,(4.42± 0.79) vs (4.88±0.87) mmol/L,(1.99±0.58) vs (3.10±0.77) mmol/L,(285.11±70.00) vs (347.70± 101.10) μmol/L (t values:from-6.25 to-2.94,all P<0.01).Logistic regression analysis revealed that season,gender,age,BMI,FBG,TG and LDL-C levels were all independent influencing factors of BAT distribution in adults (odds ratios:5.36,2.06,0.95,0.79,0.49,0.23,0.02;P<0.01 or P<0.05).Among BAT positive adults,gender and FBG levels were found to be strongly affected by the volume and glucose-uptake activity of BAT (β values:0.28,-0.21,both P<0.05).Conclusions The distribution,volume and glucose-uptake activity of BAT in adults are associated with multiple metabolic indicators including BMI,levels of glucose,lipid and UA.The distribution of BAT is affected by gender,age,season,BMI,blood glucose,and blood lipids.
