Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ²= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ²= 108 186.1, P < 0.05) and 2020-2022 (χ²= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

BackgroundLow medication compliance among patients with severe mental disorders increases the disease burden on both the patients' families and the society. Medication adherence is influenced by numerous factors. Traditional methods such as Logistic regression struggle to quantify the importance of these factors. By introducing Extreme Gradient Boosting （XGBoost） combined with Shapley Additive Explanations （SHAP）， enables the quantification of the relative contribution weights of each factor， providing support for identifying the core influencing factors. ObjectiveTo explore the influencing factors of medication adherence among patients with severe mental disorders in Zhuhai， aiming to provide references for optimizing patient management strategies. MethodsExtract the data of patients with severe mental disorders who were registered on the mental health system platform in Zhuhai City from January 1， 2023 to March 31， 2025. A total of 9 329 patients were finally included for analysis. Influencing factors were screened using univariate analysis and multivariate logistic regression analysis， and an XGBoost model combined with the SHAP algorithm was constructed to quantify the importance of each influencing factor. ResultsAmong 9 329 patients， 8 446 demonstrated medication adherence， yielding an adherence rate of 90.53%. Multivariable analysis identified several risk factors significantly associated with medication non-adherence， being unmarried （OR=1.237， 95% CI： 1.019–1.502） or divorced （OR=1.389， 95% CI： 1.038–1.832）， a diagnosis of mental retardation with psychiatric disorders （OR=3.025， 95% CI： 2.402–3.796） or paranoid psychosis （OR=5.117， 95% CI： 3.086–8.299）， a disease duration of 2–4 years （OR=1.355， 95% CI： 1.085–1.696）， 4–6 years （OR=2.143， 95% CI： 1.671–2.747）， or >6 years （OR=1.681， 95% CI： 1.365–2.079）， lack of guardian subsidies （OR=1.412， 95% CI： 1.099–1.801）， absence of a disability certificate （OR=1.900， 95% CI： 1.588–2.282）， not being enrolled in care and support groups （OR=1.384， 95% CI： 1.183–1.617） or community services （OR=1.313， 95% CI： 1.042–1.645）， and not cohabiting with a guardian （OR=1.257， 95% CI： 1.048–1.501）. Conversely， the enrollment in special outpatient disease programs （OR=0.716， 95% CI： 0.609–0.842） and a family history of mental illness （OR=0.713， 95% CI： 0.503–0.982） were identified as protective factors. The XGBoost model exhibited robust predictive performance， with a sensitivity of 0.433， specificity of 0.944， accuracy of 0.891， Area Under the Curve （AUC） of 0.837， and F1 value of 0.449. Feature importance ranking indicated that the top three factors were disease duration， diagnosis， and the acquisition of disability certificates. ConclusionPolicy-based support （acquisition of disability certificates， special outpatient disease enrollment） and clinical disease characteristics （disease duration， diagnosis type） are key factors affecting medication adherence among patients with severe mental disorders in Zhuhai City. ［Funded by Zhuhai Medical Research Project （number， 2220009000281）］

Objective:To observe the diuretic effects of Zhuling Decoction on mice with adriamycin nephropathy (ADRN); To explore its mechanism.Methods:Totally 32 SPF male C57BL/6 mice were divided into a blank group of 7 mice and a model group of 25 mice using a random number table method. ADRN model was prepared by single tail vein injection of 0.01 g/kg of amphotericin. Two weeks later, the successfully modeled mice were divided into a model group (7 mice), a furosemide group (8 mice), and a Zhuling Decoction group (8 mice). The blank group and model group mice were given equal volumes of injection water by gavage. The furosemide group was given 2.6 mg/kg of furosemide by gavage, and the Zhuling Decoction group was given 6.5 g/kg of Zhuling Decoction by gavage, once a day, for 8 consecutive weeks. Changes in body weight and urine output of mice were observed. A biochemical analyzer was used to detect 24-hour urinary protein quantification and blood potassium and SCr levels in mice. HE staining was used to observe pathological changes in mouse kidneys, and immunohistochemistry and Western blot were used to detect the homology of cyclin dependent kinase 18 (CDK18), STIP1, and the expressions of U-box protein 1 (STUB1) and aquaporin 2 (AQP2) in mouse kidney tissue cells.Results:Compared with the model group, both the furosemide and Zhuling Decoction groups exhibited increased 24-hour urine output ( P<0.05); compared with the model group and furosemide group, Zhuling Decoction group showed reduced average optical density values and protein expressions of CDK18 and AQP2 ( P<0.05) and increased STUB1 average optical density value and protein expression ( P<0.05). Conclusion:Zhuling Decoction can increase 24-hour urine output in ADRN mice, and the mechanism may be related to down-regulation of CDK18 and AQP2 protein expressions and up-regulation of STUB1 protein expression, thereby modulating the CDK18/STUB1/AQP2 pathway and reducing water reabsorption.

Objective:To understand molecular characteristics and antibiotic resistance of Clostridioides ( C.) difficile isolated from children in China, and provide data support the development of disease risk assessment and burden studies. Methods:A total of 155 strains of C. difficile isolated from children aged <12 years in 14 provinces (autonomous regions, municipalities) in China from 2010 to 2023 were used for the analyses on molecular characteristics and antibiotic resistance of C. difficile by PCR and drug susceptibility test. Results:A total of 26 sequence types (STs) and 18 ribotypes (RTs) were identified in the 155 C. difficile isolates, in which ST3 (20.65%), ST54 (16.13%), ST35 (12.90%), and RT012/ICDC007 (14.84%), RT001/ICDC001 (11.61%), RT046/ICDC018 (8.39%) were the most common. One highly virulent strain with RT078 and 27 non-toxin-producing strains were also found; the predominant toxin gene was tcdA+ tcdB+ cdt-. All the strains were sensitive to metronidazole and vancomycin, and there were 29 multidrug-resistant strains, in which 1 strain was resistant to all the seven antibiotics except for vancomycin and metronidazole. Conclusions:Molecular characteristics and antibiotic resistance of C. difficile in children were similar to those in whole population in China, but there were regional distribution differences. It is necessary to strengthen the routine drug-resistance surveillance for C. difficile infection in children in China.

Background Currently,there has been a gradual increase in the incidence of mental diseases,becoming a problem that has attracted great concern of the general public.Zhuhai is a core city of the Guangdong-Hong Kong-Macao Greater Bay Area,and the local government have attached great importance to the mental health of residents.The systematic study on the mental health has focused largely on pregnant women and medical workers,yet few are on the adult residents.Objective To investigate the prevalence and its influencing factors of anxiety and depression among adult residents in Zhuhai,so as to provide references for formulating targeted psychological intervention strategies.Methods From September 1 to December 1,2021,a cohort of 5 600 permanent residents aged 18 years and above in Zhuhai were selected through multistage sampling.All participants were subjected to complete Patients' Health Questionnaire Depression Scale-9 item(PHQ-9),Generalized Anxiety Disorder Scale-7 item(GAD-7)and National Mental Health Literacy Questionnaire based on Wenjuanxing software.Then Logistic regression was employed to identify the factors associated with anxiety and depression among the residents.Results Among the 5 600 residents,depressive symptoms were detected in 842(15.04％)residents and anxiety symptoms in 579(10.34％)residents.Logistic regression analysis yielded that female gender(OR=1.488),living in Doumen district(OR=1.942),junior college/undergraduate level(OR=3.602),postgraduate and above(OR=5.904),irregular meal pattern(OR=3.320),comorbid chronic diseases(OR=3.244),disqualification of self-assessment(OR=3.414)and disqualification of mental health skill(OR=2.131)were risk factors for depression symptoms,whereas age≥25 years old(of all age groups OR<1),monthly per capita income>20 000 yuan(OR=0.438)and exercising≥3 times a week(OR=0.431)were protective factors for depression symptoms.Age of 25～34 years old(OR=2.051),living in Jinwan district(OR=1.729)or Doumen district(OR=1.901),junior college/undergraduate level(OR=2.955),postgraduate and above(OR=6.662),irregular meal pattern(OR=2.741),comorbid chronic diseases(OR=3.535),disqualification of self-assessment(OR=3.325)and disqualification of mental health skill(OR=1.838)were risk factors for anxiety symptoms,while monthly per capita income of 6 001～9 000 yuan(OR=0.665)and exercising≥3 times a week(OR=0.572)were protective factors for anxiety symptoms.Conclusion The mental health status of adult residents in Zhuhai is affected by various factors,including gender,age,region of residence,education level,meal pattern,exercise frequency and chronic diseases.

Objective:To analyze the correlation between paraspinal muscle parameters and the angle of degenerative thoracolumbar segmental kyphosis.Methods:From November 2021 to April 2023, a total of 90 female patients with lumbar degenerative disease who underwent surgical treatment in the Department of Spine Surgery, Beijing Jishuitan Hospital were retrospectively analyzed. The average age was 67.62±4.98 years (range, 60-80 years), and the average height was 1.58±0.05 m (range, 1.48-1.70 m). Weight 63.79±9.13 kg (range, 47-90 kg), body mass index 25.48±3.35 kg/m 2 (range, 18.37-36.05 kg/m 2). The angle of kyphosis of the thoracolumbar segments was 6.65°±10.38° (range, -17.34° to 9.34°). Disease diagnosis: 32 cases of lumbar disc herniation and 58 cases of lumbar spinal stenosis. Frontal and lateral radiographs of the thoracolumbar segments in the standing position were taken to measure the angle of kyphosis of the thoracolumbar segments; quantitative CT of the thoracolumbar segments and Osirix software were used to measure the parameters of the paravertebral muscles at the levels of T 12, L 3, and L 5, including paravertebral muscle cross-sectional area, skeletal muscle area, and tissue density, the proportion of fat infiltration, and the height-corrected skeletal muscle area index. The correlation between paraspinal muscle parameters and the angle of thoracolumbar segmental kyphosis was analyzed, and the factors affecting the angle of thoracolumbar segmental kyphosis were analyzed using multiple linear regression. Results:Correlation analysis showed a negative correlation between the angle of thoracolumbar segmental kyphosis and the tissue density of T 12 skeletal muscle ( r=-0.303, P=0.004) and L 5 skeletal muscle ( r=-0.219, P=0.038). Age was negatively correlated with T 12 skeletal muscle tissue density ( r=-0.263, P=0.012), T 12 height-corrected skeletal muscle area index ( r=-0.221, P=0.036), T 12 paravertebral muscle cross-sectional area ( r=-0.280, P=0.007), L 3 skeletal muscle tissue density ( r=-0.266, P=0.011) and L 5 skeletal muscle tissue density ( r=-0.290, P=0.006). There was no correlation between bone mineral density and paravertebral muscle parameters ( P>0.05). Multiple linear regression showed that T 12 skeletal muscle tissue density ( β=-1.125, P<0.001), T 12 fat-infiltrated proportion ( β=-0.849, P=0.001), L 3 skeletal muscle tissue density ( β=0.996, P<0.001), and L 3 fat-infiltrated proportion ( β=0.496, P=0.020) were independent factors influencing the angle of thoracolumbar segmental kyphosis . Conclusion:T 12 and L 3 paraspinal muscle density and fat-infiltrated proportion are independent factors affecting the angle of thoracolumbar kyphosis. The smaller the density and fat-infiltrated proportion of T 12 paraspinal muscle, and the larger the density and fat-infiltrated proportion of L 3 paraspinal muscle, the larger the angle of thoracolumbar kyphosis.

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.
