Objective To explore the differences of regional homogeneity(ReHo)between overweight and normal weight male patients with type 2 diabetes mellitus(T2DM)during rest and their correlations with clinical features.Methods Twenty-five untreated male overweight T2DM(OW-T2DM)patients,25 untreated male normal weight T2DM(NW-T2DM)patients and 25 healthy controls(HC)were enrolled.The brain structure and resting-state functional magnetic resonance imaging(rs-fMRI)data were collected from all subjects.The brain structure and rs-fMRI data were preprocessed,and ReHo values of all brain regions were calculated for all subjects.ReHo values were compared among three groups and between groups respectively via the methods of one-way analysis of variance and two-sample t-test.To address the problem of multiple comparisons,the method of AlphaSim was performed(the threshold was set at P<0.005,the number of voxel clusters was>12).In addition,Pearson correlation analysis was performed to explore the relationships between ReHo values of the abnormal brain regions and clinical features in patients.Results(1)The brain regions showed differences of ReHo values among three groups were mainly distributed in the right hemisphere,including the superior parietal gyrus,superior marginal gyrus and superior occipital gyrus;(2)Compared with HC,NW-T2DM patients showed significantly decreased ReHo values in the right medial superior frontal gyrus,right middle cingulate gyrus and left anterior cingulate gyrus;(3)Compared with HC,OW-T2DM patients showed significantly decreased ReHo values in the bilateral postcentral gyrus and bilateral middle cingulate gyrus;(4)Compared with NW-T2DM patients,OW-T2DM patients showed significantly decreased ReHo values in the right superior parietal gyrus,right superior occipital gyrus and left cuneus;(5)ReHo values of the right medial superior frontal gyrus and right superior parietal gyrus were negatively correlated with hemoglobinA1c(HbA1c)level and body mass index(BMI),respectively,in all patients.Conclusion The occurrence of T2DM in male patients may lead to the declined activity of brain regions located in the default mode network(DMN),while overweight may further lead to decreased brain activity within the attention and visual recognition network in male T2DM patients.

Objective:To understand the prevalence of occasional hypertension in preschool children in three provinces in the middle and lower reaches of the Yangtze River in China, and analyze the relationship between their sleep status and occasional hypertension.Methods:From October to November 2017, a total of 24 842 preschool children from 109 kindergartens in 11 cities in Hubei, Anhui and Jiangsu provinces were selected by intentional sampling method. A self-made questionnaire was used to collect basic information about the subjects, and the sleep status data was collected by the Children′s Sleep Habits Questionnaire. Physical examinations were performed on the subjects, and height, weight and blood pressure were measured on-site. The difference in occasional hypertension detection rate among preschool children with different characteristics was compared, and the correlation between sleep status and occasional hypertension detection rate was analyzed by the multivariate logistic regression model.Results:The age of the subjects was (4.4±1.0) years, including 12 729 boys (51.2%). The prevalence of occasional hypertension was 31.8% (7 907/24 842). The prevalence of occasional hypertension among preschool children in three provinces of the middle and lower reaches of the Yangtze River was 31.8%. There were statistically significant differences in the detection rate of occasional hypertension among preschool children of different genders, age groups, family residence, family economic status and parents′ education level (all P values<0.05). The detection rate of occasional hypertension in children with less than 10 hours of sleep was higher than those with sufficient sleep, and the difference was statistically significant ( P<0.05). The results of multivariate logistic regression analysis showed that after adjusting for factors such as gender, age, family residence, family economic status, parental education level, parental smoking history, and physical constitution, the ORs (95% CI) for less than 10 hours of sleep, turning on the lights while sleeping, and poor sleep quality were 1.09 (1.03-1.15), 1.17 (1.07-1.28) and 1.04 (0.91-1.18), respectively, compared with the corresponding reference group. Conclusion:The detection rate of occasional hypertension is high in preschool children in the middle and lower reaches of the Yangtze River and there is a positive correlation between insufficient sleep and turning on the light when sleeping and occasional hypertension in preschool children.

Objective:To develop the Surgical Readiness Scale for Female Patients with Stress Urinary Incontinence (SUI) and test its predictive performance.Methods:Based on the theory of "patient-centered" during the perioperative period, an initial scale was formed through literature review, semi-structured interviews, expert consultation, and pre-survey. From January 2021 to December 2022, convenience sampling was used to select 585 female SUI patients who underwent elective surgical treatment at the First Affiliated Hospital of Zhengzhou University as participants for a survey to test the reliability and validity of the scale.Results:A total of 585 questionnaires were distributed, and 560 valid questionnaires were collected, with a valid response rate of 95.73% (560/585). The Surgical Readiness Scale for Female Patients with SUI included four dimensions and 28 items. The content validity index of the scale was 0.975. Cronbach's α coefficient of the total scale was 0.909, and Cronbach's α coefficients of each dimension were 0.928, 0.822, 0.958, and 0.880, respectively. The total split-half reliability coefficient was 0.712, and the split-half reliability coefficients for each dimension were 0.921, 0.808, 0.941, and 0.841, respectively. Two exploratory factor analysis showed a cumulative variance contribution rate of 64.25%. Confirmatory factor analysis showed that the chi-square degree of freedom ratio was 1.680, the mean square root of asymptotic residuals was 0.056, the goodness of fit index was 0.840, the modified goodness of fit index was 0.811, and the comparative goodness of fit index was 0.944. The convergence validity and discriminant validity values were within a reasonable range, indicating good fit of the model.Conclusions:The Surgical Readiness Scale for Female Patients with SUI has good reliability and validity, and can be used as an effective evaluation tool for the surgical readiness of female SUI patients.

【Objective】 To study the effect of macrophage mediator 1 (MED1) deficiency on atherosclerosis in female mice. 【Methods】 ApoE knockout (ApoE^-/-), LDLR knockout (LDLR^-/-), MED1^fl/fl, and macrophage MED1 knockout (MED1^△Mac) mice were recruited in the study. Two types of mouse model were constructed:ApoE and macrophage MED1 double knockout (MED1^△Mac/ApoE^-/-) mice and their littermate controls (MED1^fl/fl/ApoE^-/-). ② LDLR knockout (LDLR^-/-) mice receiving bone marrow from MED1^△Mac (MED1^△Mac→LDLR^-/-) or MED1^fl/fl (MED1^fl/fl→LDLR^-/-) mice. Female mice from these two models were fed a Western diet (21% fat and 0.15% cholesterol) for 12 weeks to promote the development of atherosclerosis. Body weight, total cholesterol (TC), and total triglyceride (TG) content in plasma were measured dynamically. After Western diet feeding for 12 weeks, aortic tree and aortic root were collected and hematoxylin-eosin (H&E) and oil red O staining were performed. 【Results】 Plasma TC and TG did not significantly differ between MED1^fl/fl/ApoE^-/- control group and MED1^△Mac/ApoE^-/-experimental group. However, the plaque area in aortic tree and aortic root was significantly increased in MED1^△Mac/ApoE^-/-mice. Moreover, compared with that in MED1^fl/fl→LDLR^-/- control group, the plaque area of aortic tree and aortic root had an increasing trend in MED1^△Mac→LDLR^-/- mice group. 【Conclusion】 MED1 deficiency in macrophages promotes the development of atherosclerosis in female ApoE or LDLR knockout mice.

Objective To observe the effects of acupuncture on spatial learning and memory ability,gut flora composition,intracerebral lipopolysaccharide content,and blood-brain barrier permeability in APP/PS1 mice.To explore the intrinsic mechanism of acupuncture in the treatment of Alzheimer′s disease.Methods 24 APP/PS1 mice were randomly divided into the model group,acupuncture group,and probiotic group,and 8 C57BL/6 mice of the same background were used as the normal control group.In the acupuncture group,acupuncture points were taken from"Baihui","YinTang",and"Zusanli"for 20 min.In the probiotic group,probiotics were given by gavage.The model group and normal control group received only restraint.The above interventions were performed once a day for 45 days.After 45 days of intervention,the feces of mice in each group were taken for 16s RNA,and spatial learning and memory skills in each group were observed by the Morris water maze test.The Lipopolysaccharide(LPS)in the brain was detected by immunofluorescence.The blood-brain barrier(BBB)structure was observed by transmission electron microscopy.Results Compared to the model group,Acupuncture improved the spatial learning and memory ability of APP/PS1 mice(P<0.05).It regulated species diversity and composition of APP/PS1 mice,and LPS was significantly decreased(P<0.05).Conclusion Acupuncture significantly improved spatial learning and memory in APP/PS1 mice,modulated BBB tight junction structure,and reduced hippocampal neuronal degeneration,and the effects were consistent with probiotics.The intrinsic mechanism of action is probably achieved by regulating intestinal flora and reducing LPS load.

Objective:To investigate the clinical efficacy of anal dimple anorectoplasty on female infants with congenital anal atresia combined rectal vestibular fistula.Methods:Clinical data of 69 female infants with congenital anal atresia combined rectal vestibular fistula admitted to Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from July 2012 to July 2022 were retrospectively analyzed.They were divided into 2 groups according to the surgical methods: 34 cases of anal dimple anorectoplasty(group A) and 35 cases of anterior sagittal anorectoplasty(group B). The operation time, length of stay, short-term complications, long-term complications and bowel function (determined by the Rintala score at 6 months postoperatively) of the two groups were compared.The difference in the incidence of postoperative complications between groups was compared by Chi- square test, and the remaining differences between groups were compared by the paired t-test. Results:The operative time [(80.18±9.29) min vs.(103.85±8.26) min] and postoperative hospital stay[(6.10±1.52) d vs.(7.63±2.40) d] in group A were significantly shorter than those of group B ( t=11.40, 2.62; all P<0.05). The Rintala total score at 6 months postoperatively in group A was significantly higher than that of group B[(19.36±0.93) points vs.(18.76±0.44) points]( t=3.20, P<0.05). There were no significant differences in the incidences of short-term [(4/34, 11.8%) vs.(7/35, 20.0%)] and long-term complications [(2/34, 5.9%) vs.(4/35, 11.4%)]between group A and group B ( χ2=0.75, 0.75; all P>0.05). Conclusions:Anal dimple anorectoplasty for female infants with congenital anal atresia combined rectal vestibular fistula is safe and effective.

Objective:To explore the prognostic predictive value of neutrophil/lymphocyte ratio (NLR) combined with prognostic nutritional index (PNI) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:Clinical data from 149 HBV-ACLF patients admitted to the infectious diseases Department of the General Hospital of Ningxia Medical University were retrospectively analyzed. Demographic data of the enrolled patients and the initial clinical-related data after admission were collected. Patients were divided into survival (93 cases) and death groups (56 cases) according to their prognostic condition 90 days after discharge. Demographic and clinical differences were compared between the two groups data. Receiver operating characteristic (ROC) curves were plotted to determine the optimal cutoff values for NLR and PNI in predicting the 90-day mortality rate of HBV-ACLF patients. The COX regression model was used to conduct univariate and multivariate analyses to investigate the correlation between NLR and PNI and the prognosis of HBV-ACLF patients. Kaplan-Meier survival analysis was used to explore the effects of NLR and PNI on the survival of HBV-ACLF patients.Results:The death group NLR was higher than that of the survival group, while the PNI was lower than that of the survival group, with a statistically significant difference. The area under the receiver operating characteristic curve (0.842, 95% CI: 0.779-0.906) showed patients with adverse prognosis assessed by NLR combined with PNI had a superior prognosis than that of the Model for End-Stage Liver Disease (MELD) and its combined serum sodium (MELD-Na) and Child-Turcotte-Pugh (CTP) scores. COX regression analysis showed that NLR≥3.03 and MELD score were independent risk factors affecting the prognosis of HBV-ACLF patients. PNI > 36.13 was a protective factor for evaluating the prognosis of HBV-ACLF patients. Conclusion:NLR combined with PNI can enhance the prognostic predictive value of HBV-ACLF.
