Objective To investigate the epidemiological characteristics and risk factors of non-alcoholic fatty liver disease in Jincheng between 2015 and 2020. Methods Clinical data of 8,578 medical check-ups at Physical Examination Center of ou hospital from January 2015 to December 2020 were retrospectively selected. The prevalence of non-alcoholic fatty liver disease in the last 5 years was recorded, and Logistic regression was utilized to identify the risk factors for the development of non-alcoholic fatty liver disease. Results The overall prevalence of non-alcoholic fatty liver disease in Jincheng was 14.57% in 2015-2020. The prevalence of non-alcoholic fatty liver disease was higher in men than in women (16.99% vs 10.98%) and highest in the 40-59 age group (18.76%). No statistical difference was reported in blood urea nitrogen (BUN) and serum creatinine (Scr) between groups (P>0.05), while statistical difference was found in diabetes, hypertension, body mass index (BMI), waist circumference, weekly exercise frequency, daily vegetable intake, triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT) and uric acid (UA) between two groups (P<0.05). Multivariate Logistic regression analysis denoted that BMI (OR=2.794, 95% CI: 1.745-4.550), waist circumference (OR=2.586, 95% CI: 1.585-4.299), diabetes (OR=0.644, 95% CI: 1.425-2.781), hypertension (OR=1.479, 95% CI: 1.121-2.290), weekly exercise ≥6h (OR=0.617, 95% CI: 0.519-0.709), daily vegetable intake ≥300g (OR=0.590, 95% CI: 0.467-0.652), TG (OR=1.481, 95% CI: 1.122-1.996), TC (OR=1.562, 95% CI:1.143-2.135), LDL-C (OR=1.440, 95% CI: 1.139-2.048), HDL-C (OR=0.656 , 95% CI: 0.587-0.783) , ALT (OR=1.591, 95% CI: 1.056-2.183), and UA (OR=1.412, 95% CI: 1.009-1.887) were risk factors for non-alcoholic fatty liver disease (P<0.05) . Conclusion The prevalence of non-alcoholic fatty liver disease in Jincheng City from 2015 to 2020 is 14.57%, the prevalence of males is higher than that of females, and the prevalence rate is the highest in the 40-59 age group. Moreover , diabetes mellitus , hypertension , BMI , waist circumference , weekly exercise , daily vegetable intake , serum TG, TC, LDL-C, HDL-C, ALT, and UA are all associated with the risk of the disease.

OBJECTIVES: This study aimed to investigate the potential mediating role of plasma phosphorylated tau217 (p-tau217) in the association between periodontitis and mild cognitive impairment (MCI). METHODS: In this case-control study, patients diagnosed with MCI in the Neurology Department of the First Affiliated Hospital of Shandong Second Medical University from November 2023 to May 2024 were selected as the case group (MCI group). Cognitively normal (CN) volunteers, matched for age and education level and recruited from the physical examination center during the same period, served as the control group (CN group). The general demographic data of the study participants were collected. The Beijing versions of the Montreal Cognitive Assessment (MoCA), clinical dementia rating (CDR), and activities of daily living scale (ADL) were used to assess neuropsychological functions. Clinical periodontal examinations were conducted, the periodontal inflamed surface area (PISA) was calculated, and the periodontitis stage was determined in accordance with the 2018 classification. Fasting elbow venous blood samples were collected in the morning, and blood biochemical indicators were measured. Plasma p-tau217 levels were detected using enzyme-linked immunosorbent assay (ELISA). Statistical analyses were performed using t-test, Mann-Whitney U test, chi-square test, partial correlation analysis, multivariate Logistic regression analysis, multiple linear regression analysis, restricted cubic spline (RCS) regression analysis, and mediation effect analysis. RESULTS: Among the 192 participants, 96 belong to the MCI group and 96 to the CN group. The prevalence of periodontitis was 63.5% in the MCI group and 43.8% in the CN group, with a statistically significant difference (χ²=7.561, P=0.006). The plasma p-tau217 levels in the MCI group were significantly higher than those in the CN group [7.00 (4.27-9.65) ng/mL versus 2.02 (0.80-3.81) ng/mL, Z=-8.108, P<0.001]. Partial correlation analysis revealed that plasma p-tau217 levels were positively correlated with all the clinical periodontal indices (all P<0.001). After adjustments for baseline covariates, multivariate Logistic regression indicated that periodontitis was an independent risk factor for MCI. Patients with periodontitis had a 1.977-fold higher MCI risk than those without periodontitis (OR=1.977, 95%CI: 1.088-3.594, P=0.025). Moreover, the MCI risk for stage Ⅰ/Ⅱ periodontitis and stage Ⅲ/Ⅳ periodontitis was 1.878 times (OR=1.878, 95%CI: 1.029-3.425, P=0.040) and 2.625 times (OR=2.625, 95%CI: 1.073-6.246, P=0.035) higher than that for patients without periodontitis, respectively. Trend test showed that the MCI risk increased with periodontitis severity (P_trend=0.016). After adjustments for baseline covariates, multiple linear regression analysis showed that periodontitis was an independent risk factor for increased plasma p-tau217 levels (β=3.309, 95%CI: 2.363-4.254, P<0.001). Compared with patients without periodontitis, those with stage Ⅰ/Ⅱ periodontitis (β=1.838, 95%CI: 0.869-2.806, P<0.001) and stage Ⅲ/Ⅳ periodontitis (β=5.539, 95%CI: 4.442-6.636, P<0.001) had significantly higher plasma p-tau217 levels. In addition, trend test indicated that plasma p-tau217 levels increased with periodontitis severity (P_trend<0.001). After adjustments for baseline covariates, RCS regression analysis further revealed that PISA had a positive linear dose-response relationship with MCI risk (P_overall=0.002, P_nonlinear=0.344) and plasma p-tau217 levels (P_overall<0.001, P_nonlinear=0.140). After adjustments for baseline covariates, mediation analysis showed that plasma p-tau217 mediated the association between periodontitis and MCI, with a mediation proportion of 13.99% (95% Bootstrap CI: 0.38%-49.39%, P=0.038). CONCLUSIONS Periodontitis was independently positively associated with MCI risk, and plasma p-tau217 plays a mediating role in this association.

Bacillus velezensis DJ1 exhibits broad-spectrum antagonistic activity against diverse phytopathogenic fungi, while its biocontrol mechanisms against Fusarium graminearum, the causal agent of maize stalk rot, remain poorly characterized. In this study, we integrated genomics and transcriptomics to elucidate the antifungal mechanisms of strain DJ1. The results demonstrated that DJ1 inhibited F. graminearum with the efficacy of 64.4%, while its polyketide crude extract achieved the control efficacy of 55% in pot experiments against this disease. Whole-genome sequencing revealed a single circular chromosome (3 929 792 bp, GC content of 47%) harboring 12 biosynthetic gene clusters for secondary metabolites, six of which encoded known antimicrobial compounds (macrolactin H, bacillaene, difficidin, surfactin, fengycin, and bacilysin). Transcriptomic analysis identified 243 differentially expressed genes (152 upregulated and 91 downregulated, P < 0.05), which were potentially associated with the antagonistic activity against F. graminearum. KEGG enrichment analysis highlighted activation (P < 0.05) of cysteine/methionine metabolism, pentose phosphate pathway, and polyketide biosynthesis pathways, indicating that DJ1 employed synergistic strategies involving antimicrobial compound synthesis, energy metabolism enhancement, and nutrient competition to suppress pathogens. This study provides a theoretical foundation for developing novel microbial resources and application technologies to combat phytopathogenic fungi.

Objective:To investigate the clinical characteristics and treatment of patients with perianal necrotizing fasciitis.Methods:This study was a retrospective cohort study. Twenty patients with perianal necrotizing fasciitis who met the inclusion criteria were admitted to the Department of Burn and Plastic Surgery of the First Affiliated Hospital of Guangxi Medical University (hereinafter referred to as our department) from August 2013 to September 2023, including 19 males and 1 female, aged 24-74 (56±11) years. Based on the spreading route of perianal infection to the lower abdomen, the patients were divided into perianal-inguinal-lower abdominal wall group (12 cases) and perianal-pelvic cavity-retroperitoneal group (8 cases). The following clinical data were compared between the two groups of patients: general data, including gender, age, combined underlying diseases, blood glucose level and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score when admitted to our department, and laboratory risk indicator for necrotizing fasciitis (LRINEC) score when admitted to our department and at 14 d after admitted to our department; infection indicators when admitted to our department, including C-reactive protein level, white blood cell count, lymphocyte count, procalcitonin level, and lactic acid level; clinical outcome-related indicators, including time from onset to definite infection range, number of surgery, treatment in intensive care unit (ICU), length of hospital stay, treatment outcome, and recurrence of necrotizing fasciitis during follow-up; detection of pathogen and bacterial drug resistance in wound necrotic tissue specimen when admitted to our department.Results:Compared with those in perianal-inguinal-lower abdominal wall group, the APACHE Ⅱ score and lactic acid level when admitted to our department and LRINEC score at 14 d after admitted to our department (with t values of -5.98, -5.01, and -2.86, respectively, P<0.05) and ICU treatment ratio ( P<0.05) were significantly increased, the time from onset to definite infection range was significantly prolonged ( Z=-3.75, P<0.05), and the number of surgery was significantly increased ( Z=2.80, P<0.05) in patients in perianal-pelvic cavity-retroperitoneal group. There were no statistically significant differences in other data between the two groups of patients ( P>0.05). Eighteen patients were cured, and no recurrence of perianal necrotizing fasciitis was observed during follow-up of 6 months in 18 cured patients. The main bacteria were Escherichia coliand Klebsiella pneumoniae, and the fungui were Aspergillus and Candida albicans detected in wound necrotic tissue specimens in two groups of patients when admitted to our department. The ratio of multiple drug resistance of bacteria in wound necrotic tissue specimens in perianal-pelvic cavity-retroperitoneal group of patients was significantly higher than that in perianal-inguinal-lower abdominal wall group ( P<0.05). Conclusions:Perianal necrotizing fasciitis can spread to the lower abdomen through two routes: the perianal-inguinal-lower abdominal wall route and the perianal-pelvic cavity-retroperitoneal route. The latter is more insidious in disease progression and more challenging in treatment. Establishing a mechanism of multi-disciplinary team diagnosis and treatment can achieve the goal of early diagnosis and precise treatment of perianal necrotizing fasciitis.

ObjectiveTo investigate the effect of Chaihu Guizhitang on triple-negative breast cancer （TNBC） cells based on hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor A （VEGFA） signaling pathway. MethodTNBC xenograft model was established and the cells were randomized into model group， capecitabine group （0.2 mg·kg^-1）， Chaihu Guizhitang low-dose group， medium-dose group， and high-dose group （10.62， 21.23， 42.46 g·kg^-1）， with 10 mice in each group. After 21 days of medication， the content of tumor necrosis factor-α （TNF-α） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. The expression of HIF-1α mRNA was detected by real-time fluorogenic quantitative polymerase chain reaction （real-time PCR）. Immunohistochemistry （IHC） was employed to detect the expression of HIF-1α， TNF-α， and VEGFA in tumor tissues， and CD34 staining to examine the angiogenesis in tumor tissues. Microvessel density （MVD） was calculated， and the protein expression of HIF-1α， VEGFA， and epidermal growth factor receptor （EGFR） in tumor tissues was measured by Western blot. ResultCompared with the model group， the rest four groups showed low levels of TNF-α （P<0.01）， HIF-1α mRNA （P<0.01）， expression of HIF-1α， TNF-α， VEGFA， and CD34 in cells， and MVD （P<0.05， P<0.01）， and low protein levels of HIF-1α， VEGFA， and EGFR （P<0.01）. Compared with capecitabine group， medium-dose and high-dose Chaihu Guizhitang decreased the level of TNF-α （P<0.01）， HIF-1α mRNA （P<0.01）， expression of HIF-1α， TNF-α， and VEGFA in cells （P<0.01）， CD34 expression， MVD， and protein levels of HIF-1α， VEGFA， and EGFR （P<0.01）. ConclusionChaihu Guizhitang may inhibit the angiogenesis in TNBC cells by regulating the expression of HIF-1α/VEGFA signaling pathway， thus exerting anti-tumor effect.

Objective:To explore the application effect of painting art therapy in young and middle-aged patients with maintenance hemodialysis, and to provide reference for clinical nursing.Methods:Adopted the convenience sampling method to collect 90 young and middle-aged patients undergoing maintenance hemodialysis in the Hemodialysis Room of Taihe County Hospital of Traditional Chinese Medicine. They were divided into two groups according to the time of enrollment. The patients enrolled from March 2018 to March 2019 served as the control group, and the patients enrolled from April 2019 to March 2020 served as the study group. There were 45 cases in each group. Both groups were given routine nursing care, and the study group received 4 times of painting art therapy on this basis. Before and after the intervention, the effects were assessed by the Revised Piper Fatigue Scale (PFS-R) and the Pittsburgh Sleep Quality Index (PSQI).Results:Finally, there were 44 cases in the control group and 43 cases in the study group. Before the intervention, there were no significant differences in the observation indicators between the two groups (P>0.05). After the intervention, scores of sensory, emotional, cognition, behavioral demensions and total fatigue scores of PFS-R were (3.33 ± 1.02), (4.47 ± 1.42), (3.56 ± 0.79), (3.26 ± 0.76) and (3.65 ± 0.57) in the study group, significantly lower than those in the control group (5.41 ± 1.13), (6.07 ± 1.37), (4.95 ± 1.21), (4.43 ± 0.87) and (5.22 ± 0.51) (t values were 5.14-13.30, all P<0.05). Scores of sleep quality, sleep duration, sleep efficiency factor score and PSQI total score were (0.95 ± 0.20), (1.71 ± 0.33), (1.10 ± 0.21) and (9.13 ± 0.60) in the study group, which were significantly lower than those in the control group (1.13 ± 0.19), (1.90 ± 0.24), (1.35 ± 0.31) and (9.90 ± 0.71), the differences were statistically significant (t values were 2.95 - 5.44, all P<0.05).Conclusions:Painting art therapy can effectively relieve fatigue symptoms and improve sleep quality in young and middle-aged patients with maintenance hemodialysis.

Objective: To analyze the epidemiological characteristics and associated factors of delayed voiding among middle school students, and to provide the basis for health education. Methods: A total of 1 260 middle school students were selected from Sanmen country in Taizhou by using multi-stage stratified sampling method. A cross-sectional survey was conducted to investigate the demographic characteristics, epidemiological characteristics and associated factors of delayed voiding by questionnaire. Results: The proportion of frequent delayed voiding among middle school students was 14.37%(181). The proportion among senior high school students was 15.51%(90), and among junior high school students was 13.67%(91)，no significant differences were found by grade(χ2=0.57, P=0.45). The multivariate Logistic regression analysis showed that residential school, homework per day >2 hours, games and reduce the frequency of drinking ≥7 times/week were risk factors for delayed voiding frequently in junior high school students(OR=3.71, 1.70, 3.02,6.52，P<0.05). Higher than 2 hours of daily homework, a supportive or indifferent attitude to delayed voiding, staying in bed after waking up, drinking <0.5 L/d or ≥2.0 L/d, and reduce the frequency of drinking ≥7 times/week were risk factors for delayed voiding behavior in high school students(OR=2.23, 1.81, 2.22, 3.48, 2.69, 3.00, P<0.05). Conclusion The prevalence of frequent delayed voiding was high among middle school students. Attitude, environment and the quality of drinking water were the primary factors of frequent delayed voiding.

Objective: To study the clinicopathologic features of intraductal papillary neoplasm of the bile duct(IPNB) and to analyze the diagnostic and therapeutic patterns. Methods: The data of 46 patients with IPNB undergoing surgery in Department of Hepatobiliary and Pancreatic Surgery, the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2013 to November 2017 were retrospectively analyzed.There were 23 males and 23 females with age of (64±8)years.Patients were followed up by clinics and telephone inquiry.Categorical data were compared with χ² test or Fisher′s exact test. Results: Abdominal pain(in 31 patients), fever (in 15 patients) and jaundice (in 11 patients) were the most common symptoms.Twenty-five patients were accompanied with cholangiolithiasis and 25 were accompanied with liver atrophy.Preoperative laboratory examination was mainly manifested as the abnormal liver function caused by biliary obstruction.Typical imaging findings included bile duct dilation (in 45 patients) and mass within bile duct (in 22 patients). All the patients were diagnosed as IPNB histopathologically.Among them, high-grade intraepithelial neoplasia and related adenocarcinoma were more common in mucus-hypersecretion IPNB ((13/15 vs. 51.6%(16/31))(χ²=5.331, P=0.021). Hepatectomy was performed in 25 patients, hepatectomy combined with biliary resection and reconstruction in 12 cases, biliary resection and reconstruction in 3 cases, pancreatoduodenectomy in 3 cases, hepatopancreaticoduodenectomy in 1 case, liver transplantation in 1 case and radiofrequency ablation in 1 case.Forty-one patients were followed up with a median of 30 (12, 41) months.Seven patients suffered recurrence and 6 died. Conclusion IPNB is a rare disease with limited knowledge currently.Images are the main diagnositc means and surgery is the first choice.
