Objective This study aims to investigate the epidemiological characteristics of mental disorders in a rural town of Huazhou City,Guangdong Province,and explore their association with the rural revitalization strategy,so as to provide evidence for policy formulation.Methods A combination of questionnaire surveys and in-depth interviews was used to collect in-formation on the demographic characteristics,disease status,economic conditions,and policy awareness of registered mental dis-order patients in the town.Semi-structured interviews were also conducted with local doctors and village committee members.Da-ta were analyzed using descriptive statistics and logistic regression models to assess the impact of awareness of rural revitalization policies on patients'income.Results The average age of the study subjects was 47.71 years,with an average disease duration of 18.38 years.A total of 86.36％of patients had a family history of mental disorders.After onset,42.11％of patients had an annual income≥￥ 10 000,which was an increase compared to pre-illness levels,but 60.75％had completely lost their ability to work.Awareness of rural revitalization policies was low(only 18.29％were fully aware),but policy awareness was significant-ly associated with increased patient income(OR=18.03,P＜0.001).Additionally,medical expenditures were significantly higher among female patients than male patients(P＜0.001).Conclusion In a town in Huazhou City,Guangdong Province,60.75％of mental disorder patients have completely lost their ability to work,while 42.11％have an annual income exceeding ￥ 10,000.Income is positively correlated with policy awareness(OR=18.03).It is recommended to strengthen policy promo-tion,optimize the allocation of medical resources,and develop specialized assistance programs to promote the coordinated devel-opment of mental health and rural revitalization.

AIM:To investigate the effects of nebulized sodium tanshinone ⅡA sulfonate(STS)in a mouse model of pulmonary hypertension associated with chronic obstructive pulmonary disease(COPD-PH).METHODS:A to-tal of 32 healthy SPF-grade male C57BL/6 mice were randomly divided into 4 groups:control(CTL,n=8)group,COPD-PH(CS+LPS,n=8)group,STS-treated COPD-PH(CS+LPS+STS,n=8)group,and STS(n=8)group.The COPD-PH model was established through whole-body exposure to cigarette smoke(CS)combined with lipopolysaccharide(LPS)in-halation.Mice were subjected to cigarette smoke exposure in a chamber(9 cigarettes/h,2 h/session,2 sessions/d,6 d/week)for 60 d,except on days of LPS inhalation.On days 1 and 14,COPD-PH model mice received LPS(7.5 μg/mouse in 50 μL saline)via intranasal inhalation,while the CTL and STS groups received an equivalent volume of saline.STS was administered via nebulized inhalation(5 mg/kg,30 min per session,twice daily)immediately before CS exposure.At the end of the modeling period,lung function and right heart pressure were assessed.Bronchoalveolar lavage fluid(BALF)was collected for inflammatory cell counting.Levels of interleukin-6(IL-6)in BALF supernatants and plasma were measured using ELISA.Pathological changes in the airway and lung tissues were evaluated.RESULTS:(1)Com-pared to CTL mice,those exposed to CS and LPS exhibited lesions characteristic of COPD-PH,including emphysema,lung inflammation,decreased lung function,and increased right ventricular systolic pressure(RVSP)and right ventricu-lar hypertrophy index(RVHI)(P<0.05);(2)COPD-PH mice showed significantly elevated IL-6 levels in both BALF and plasma(P<0.05);(3)STS treatment alleviated emphysema and lung inflammation,improved lung function,prevent-ed increases in RVSP and the RV/(LV+S)ratio,and reduced IL-6 levels in both BALF and plasma(P<0.05).CON-CLUSION:The results indicate that nebulized inhalation of STS significantly slows the progression of COPD-PH,likely due to its ability to inhibit lung inflammation and reduce IL-6 expression in the lungs.

The detection rate of carbapenem-resistant Enterobacter cloacae(CRECL)in clinical practice has risen steadily in recent years,and it has become one of the main pathogens of hospital-acquired infections.CRECL resistance is primarily driven by carbapenemase-encoding genes(CEG),which can spread through multiple mechanisms under the selective pressure of antibiotics and other environmental factors.This gene transfer significantly hampers antimicrobial treatment and infection control efforts.This review outlines the current understanding of CEG distribution in CRECL,key transmission pathways,and their public health im-plications.The findings aim to support the development of effective strategies for the prevention and manage-ment of CRECL infections.

Background and Objectives: Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of all heart failure hospitalizations and disproportionately affects women, who present with distinct risk profiles and pathophysiologies compared to men. Prior studies exploring sex differences have been limited by small sample sizes and have often focused on index hospitalizations. We aimed to examine sex differences in risk factors, causes of readmission, and mortality following HFpEF hospitalization using a large, nationally representative cohort. Methods: We performed a retrospective cohort study using the 2016–2019 National Readmissions Database. Adults hospitalized with a primary diagnosis of HFpEF were included. Patients were followed for 90-day readmissions, and multivariable logistic regression was used to identify predictors of readmission and readmission-related mortality, stratified by sex. The final sample included 353,536 patients (217,354 women and 136,182 men). Results: Women were older at admission, more likely to live in lower-income areas, and more often presented with uncomplicated hypertension, while men had a higher burden of ischemic heart disease. Advancing age was associated with increased risk of readmission in women.Women were more frequently readmitted with respiratory failure, diastolic heart failure, and atrial fibrillation, suggesting a greater burden of vascular stiffness and symptom severity. Chronic kidney disease and diabetes were key predictors of readmission and mortality in both sexes. Conclusions HFpEF manifests with distinct sex-specific risk factors, clinical trajectories, and outcomes. These findings underscore the need for sex-informed, individualized treatment strategies and equitable resource allocation to reduce disparities and improve outcomes in HFpEF care.

Chlamydia trachomatis (CT) infection is the most prevalent sexually transmitted bacterial disease worldwide. However, unlike that in female infertility, the role of CT infection in male infertility remains controversial. The objective of this retrospective study was to explore the impacts of CT infection in the genital tract on sperm quality, sperm acrosin activity, antisperm antibody levels, and inflammation in a large cohort of infertile males in China. A total of 7154 semen samples were collected from infertile male subjects, 416 of whom were CT positive (CT+ group) and 6738 of whom were CT negative (CT- group), in our hospital between January 2016 and December 2018. Routine semen parameters (semen volume, pH, sperm concentration, viability, motility, morphology, etc.), granulocyte elastase levels, antisperm antibody levels, and sperm acrosin activity were compared between the CT+ and CT- groups. Our results showed that CT infection was significantly correlated with an abnormally low semen volume, as well as an increased white blood cell count and granulocyte elastase level (all P < 0.05) in the semen of infertile males; other routine semen parameters were not negatively impacted. The antisperm antibody level and sperm acrosin activity were not affected by CT infection. These findings suggested that CT infection might contribute to inflammation and hypospermia but does not impair sperm viability, motility morphology, and acrosin activity or generate antisperm antibodies in the infertile males of China.

Objective:To observe the changes of abdominal aortic calcification and biochemical indicators after parathyroidectomy (PTX) in the maintenance hemodialysis (MHD) patients with secondary hyperparathyroidism (SHPT).Methods:The MHD patients with SHPT who were followed up for 2 years were analyzed retrospectively and divided into PTX surgery group ( n=26) and non-surgery group ( n=18) according to whether they underwent PTX, and then the abdominal aortic calcification score (AACS), intact parathyroid hormone (iPTH), blood calcium and phosphorus after 2 years were observed in the two groups. The PTX surgery group was divided into advanced group and non-advanced group according to whether abdominal aortic calcification had progressed or not 2 years after the operation. Indicators such as age, dialysis age, iPTH, blood calcium, blood phosphorus, calcium and phosphorus product were compared between the two groups to analyze the possible factors related to the development of abdominal aortic calcification. Results:A total of 44 patients meeting the inclusion criteria were included, with 26 in the PTX surgery group and 18 in the non-surgery group. The baseline data of the PTX surgery group and the non-surgery group showed statistical difference in the age of dialysis ( P<0.05), but no statistical differences in gender, age and history of hypertension. Compared with preoperative indicators, postoperative iPTH, blood calcium and phosphorus significantly reduced (all P<0.05), and there was no significant difference in AACS. There were 8 cases (30.77%) of accelerating progress of calcification, 8 cases (30.77%) of improvement in calcification, 10 cases (38.46%) of calcification stability. After 2 years, iPTH value of non-advanced group was significantly lower than advanced group [(20.62±6.44) ng/L vs (132.72±76.83) ng/L], while the preoperative AACS progress was higher in non-advanced group [(13.11±2.71) vs (2.00±1.41)] (all P<0.05). In non-surgery group, AACS was significantly higher after 2 years [(10.44±1.65) vs (8.05±1.26)], blood phosphorus and the product of blood calcium and phosphorus significantly decreased (all P<0.05) , and the levels of iPTH and blood calcium did not significantly change. Pearson correlation analysis showed that the decreased value between preoperative AACS and 2-year postoperative AACS was positively correlated with the decreased value of iPTH ( r=0.534, P=0.012), blood calcium ( r=0.643, P=0.004), blood phosphorus ( r=0.897, P<0.001) and calcium-phosphorus product ( r=0.568, P=0.021) , and negatively correlated with preoperative AACS ( r=-0.647, P=0.014). Conclusions:Small sample data shows that PTX can correct parathyroid hormone, calcium and phosphorus for long term, and prevent abdominal aortic calcification progression, even reverse vascular calcification. Whether abdominal aortic calcification improves or not may be associated with the decrease of iPTH, calcium, phosphorus and the product of blood calcium and phosphorus.

Objective: To investigate the clinical efficacy of daytime continuous blood purification (DCRRT) combined with plasma exchange in the treatment of severe acute pancreatitis. Methods: The clinical data of 49 patients with non-biliary severe acute pancreatitis admitted to the First People's Foshan Hospital from January 2012 to January 2019 were analysed respectively. The enrollees were randomized into DCRRT combined with plasma exchange (combination therapy) group and DCRR only (DCRR) group using a random number table method. All patients received DCRRT therapy [8 hours continuous venous-venous blood purification/day (CVVH/d)] immediately after the diagnosis of non-biliary severe acute pancreatitis was established. The combination group received at least one plasma exchange during the course of treatment. The differences of laboratory examination and prognosis between the two groups before and after treatment were compared. Results: A total of49 patients were enrolled, including 29 males and 20 females, with age of (46.40±17.81) years. There were 24 patients in the combination therapy group and 25 patients in DCRR group. There were no significant differences in the age, gender, body mass index (BMI), and pre-treatment laboratory findings between the two groups. After treatment, the blood glucose, hypersensitive C-reactive protein (hs-CRP), procalcitonin (PCT-u), amylase, lipase, triglyceride, cholesterol, serum creatinine were lower than those before treatment (all P<0.05). The blood hs-CPR, PCT-u, lipase and triglyceride in the combination therapy group were significantly lower than those in the DCRR group (all P<0.05). The acute physiology and chronic health scores (APACHEⅡ) of the two groups were lower than those before treatment, and the combination therapy group was more significant than DCRR group (all P<0.05). There were 5 deaths (20.83%) in the combination therapy group and 7 deaths (28.00%) in DCRR group. There was no significant difference in mortality between the two groups. There was no significant difference in the start time and duration of DCRRT between the two groups. Conclusions DCRRT or combined plasma exchange therapy can effectively treat non-biliary severe acute pancreatitis. DCRRT combines with plasma exchange therapy can more effectively remove inflammatory factors and reduce APACHEⅡ score.

Objective To investigate the clinical efficacy of renal transplantation from donors of donation after brain and cardiac death(DBCD) complicated with acute kidney injury (AKI),and summarize the clinical experience of evaluation and application.Methods The clinical data of the 45 DBCD donors and 80 recipients in the First People's Hospital of Foshan from September 2011 to September 2015 were retrospectively analyzed.DBCD donors were classified into the AKI group (n=26) and non-AKI group (n=19) according to the serum creatinine level and urine output when the donors were admitted to the intensive care unit (ICU) in this hospital.A total of 80 recipients were divided into the AKI group (n=46) and non-AKI group (n=34) correspondingly.The condition of the donors before organ procurement between the two groups was compared,and the incidence of various complications,the 1 years survival rates of recipients and graft after renal transplantation were compared between the two groups.Results Among 45 donors,26 cases(57.8％) suffered from AKI.The serum creatinine of donors was significantly higher in the AKI group than that in the non-AKI group (P ＜ 0.01).The incidence of delayed graft function (DGF) in AKI group and non-AKI group was 21.7％ and 8.8％ respectively (P ＞ 0.05).After 1 years,the serum creatinine of the recipients in AKI group was significantly higher than that in non-AKI group [(134.9±63.4) μmol/L vs (106.6±28.2) μmol/L,P＜ 0.05],but the survival rates of recipients and grafts did no differ between the two groups (both P ＞ 0.05).Conclusions The donors combined with AKI do nothave a worse effect on the incidence of DGF,the 1-year survival rates of recipients and grafts after transplantation.So,the donors with AKI for transplantation can widen the origin of kidney grafts.
