Objective:To gain a understanding of the occurrence of cognitive impairment among residents in drinking water-borne endemic fluorosis (drinking water-borne fluorosis) areas, and to study its influencing factors.Methods:In March 2023, a cluster sampling method was used to select local residents aged 18 and above from the drinking water-borne fluorosis areas in Jishan County, Shanxi Province as survey subjects. General demographic data were collected through face-to-face surveys, and a random urine sample was collected once to determine urinary fluoride level. Cognitive function was assessed using the mini-mental state examination (MMSE), and the survey subjects were divided into a cognitive impairment group ( < 27 points) and a control group (27 - 30 points) based on the MMSE scores. A multiple logistic regression model and a decision tree model based on chi-squared automatic interaction detector were constructed to analyze the factors affecting cognitive impairment, and the model fitting effect was evaluated using receiver operating characteristic (ROC) curve.Results:A total of 3 301 subjects were included in the survey, including 2 081 females and 1 220 males. There were 1 515 subjects < 60 years old and 1 786 subjects ≥60 years old, with urinary fluoride level [ M ( Q1, Q3)] of 2.92 (1.78, 4.54) mg/L. There were 1 939 cases in the cognitive impairment group and 1 362 cases in the control group, with a detection rate of 58.74% (1 939/3 301) for cognitive impairment; and the differences in gender, age, education level, marital status, annual household income, alcohol consumption, smoking distribution, and urinary fluoride level between the two groups were statistically significant ( P < 0.05). The results of multiple logistic regression analysis showed that female, ≥60 years, and urinary fluoride > 4.54 mg/L were risk factors for cognitive impairment [ OR (95% CI): 1.25 (1.01, 1.54), 2.66 (2.26, 3.14), 1.32 (1.06, 1.65), P < 0.05]. Education level of primary school or above, annual household income≥12 000 yuan, and mild alcohol consumption were protective factors for cognitive impairment [ OR (95% CI): 0.15 (0.09, 0.25), 0.58 (0.48, 0.68), 0.67 (0.51, 0.87), P < 0.05]. The analysis results of the decision tree model showed that age had the greatest impact on the occurrence of cognitive impairment, followed by annual household income, education level, and urinary fluoride. The areas under the ROC curves of the multiple logistic regression and decision tree model were 0.72 and 0.70 ( P < 0.001), respectively, indicating good model fitting performance. Conclusion:The detection rate of cognitive impairment in residents of drinking water-borne fluorosis areas is relatively high, and age, annual household income, education level, and urinary fluoride are all influencing factors for occurrence of cognitive impairment.

Objective:To investigate the characteristics of resting-state mirror homotopic connectivity and the gray matter volume of brain in patients with neuropsychiatric systemic lupus erythematosus (NPSLE).Methods:From June 2020 to March 2023, a total of 35 NPSLE patients (NPSLE group) and 30 non-NPSLE patients (non-NPSLE group) were selected from Taizhou People's Hospital Affiliated to Nanjing Medical University, another 31 healthy volunteers were recruited as the healthy controls(HC group). All participants underwent resting-state functional magnetic resonance imaging (rs-fMRI) and mini-mental state examination (MMSE) assessments. The patients in NPSLE and non-NPSLE groups were additionally assessed using the fatigue scale for motor and cognitive functions (FSMC) and the hospital anxiety and depression scale (HADS).The DPABI V7.0 toolkit based on the MATLAB platform was used to preprocess the rs-fMRI data and calculate the voxel-mirrored homotopic connectivity(VMHC) indexes, and the differences in VMHC between groups were evaluated by covariance analysis in SPM12.0 software, and the VMHC values of brain regions with significant differences were extracted for further comparison between the two groups.Partial correlation analysis was performed to investigate the association between VMHC values and clinical parameters in NPSLE patients.The brain regions with significant differences between NPSLE patients and non-NPSLE patients were used as region of interest (ROI), and gray matter volumes within these ROIs were then calculated by VBM8 toolbox.Results:(1)There were statistically significant differences in the VMHC values of bilateral precentral gyrus, bilateral dorsolateral superior frontal gyrus, bilateral medial and paracingulate gyrus, bilateral parahippocampal gyrus, bilateral middle occipital gyrus, bilateral postcentral gyrus, and bilateral superior temporal gyrus among the 3 groups( F=11.246-14.102, all P<0.05). The NPSLE group exhibited significantly lower VMHC values in these regions compared to both the non-NPSLE group and HC group (all P<0.05), but there were no significant differences in these regions between the non-NPSLE group and HC group (all P>0.05).(2) The gray matter volumes of bilateral dorsolateral superior frontal gyrus(right: (0.57±0.11)mm 3, (0.65±0.08)mm 3, t=-3.409, P=0.001; left: (0.53±0.10)mm 3, (0.60±0.07)mm 3, t=-3.082, P=0.003), bilateral precentral gyrus(right: (0.32±0.06)mm 3, (0.35±0.04)mm 3, t=-2.044, P=0.045; left: (0.39±0.06)mm 3, (0.42±0.04)mm 3, t=-2.505, P=0.015), right medial and paracingulate gyrus((0.66±0.08)mm 3, (0.70±0.07)mm 3, t=-2.491, P=0.015) and left superior temporal gyrus((0.57±0.09)mm 3, (0.61±0.06)mm 3, t=- 2.344, P=0.022) in the NPSLE group were smaller than those of non-NPSLE group.(3)Correlation analysis showed that the VMHC value of dorsolateral superior frontal gyrus was positively correlated with IgA level in NPSLE patients ( r=0.353, P=0.047). Conclusion:Patients with NPSLE generally have decreased mirror homotopy functional connectivity in the cerebral hemispheres, accompanied by a decrease in gray matter volume in some brain regions, which can provide a certain neuroimaging basis for the pathogenesis of brain injury.

Objective To explore the changes in serum pro-inflammatory cytokine factor and their relationship with memory function in patients with chronic insomnia comorbid and depression(ICD).Methods A total of 40 ICD patients and 41 chronic insomnia disorder(CID)patients were recruited at the Clinic of Sleep Disorder,and concurrently 41 healthy individuals as controls(CON)were recruited during the same period.The Pittsburgh sleep quality index(PSQI)and 17-item Hamilton depression rating scale(HAMD-17)were used to assess the severity of insomnia and depression in the subjects,and the nine box maze was used to evaluate their memory function.Enzyme linked immunosorbent assay was used to detect the levels of serum tumor necrosis factor(TNF)-α,TNF-β,interleukin(IL)-1β,IL-6,and serum amyloid A(SAA),and the correlation between pro-inflammatory cytokine factor levels and cognitive function was analyzed.Results The HAMD and PSQI scores were significantly higher in ICD and CID groups than in CON[HAMD:19.0(14.0,22.0)vs.10.0(7.5,12.5)vs.2.0(1.0,4.0);PSQI:17(15,19)vs.15(13,16)vs.2(0,3);P<0.01]which was also higher in ICD group than in CID group(P<0.01).The number of errors in spatial reference memory(SRM)and spatial working memory(SWM)were higher in the ICD and CID groups than in CON[SRM:2.5(1.0,4.0),vs.1.0(0,3.0)vs.0(0,1.0);SWM:5.00(4.00,7.75)vs.4.00(2.00,5.00)vs.1.00(1.00,2.50);P<0.01].The number of errors were also higher in SRM and SWM in ICD group than in CID group(P<0.01).The serum levels of TNF-α,TNF-β,IL-1β,IL-6,and SAA were higher in ICD and CID groups than in CON(P<0.01),and the serum levels of TNF-β and IL-6 were also higher in ICD group than in the CID group(P<0.01).In the ICD group,the partial correlation analysis showed that TNF-α(r=0.394,P=0.021)and IL-1β(r=0.398,P=0.020)were positively correlated with the number of SRW errors,while TNF-β(r=0.381,P=0.026)and SAA(r=0.446,P=0.008)were positively correlated with the number of SWM errors.TNF-β were also positively correlated with the number of recognition memory errors(r=0.347,P=0.044).Conclusion ICD patients have memory impairment,which may relate to increased levels of pro-inflammatory cytokine factor in their serum.

Objective: To investigate the influencing factors of overactive bladder (OAB) in college freshmen and the impacts of OAB on their mental health, quality of life and social interaction. Methods: An epidemiological questionnaire survey was conducted in an anonymous manner on the prevalence of OAB among 5300 freshmen aged 17 to 22 years enrolled in the 2023—2024 academic year in Xinxiang Medical University and Sanquan College of Xinxiang Medical University.The questionnaire included questions on basic information, history of urinary tract infection, constipation, smoking, history of alcohol consumption, history of coffee/strong tea drinking, history of carbonated beverage drinking, redundant prepuce, phimosis, holding urine, chronic insomnia, self-rating anxiety scale (SAS), quality of life score (QoL), and social avoidance and distress scale (SADS).The influencing factors of OAB were analyzed with multivariate logistic regression analysis.The subjects were grouped according to whether they had OAB, and the differences in SAS, QoL and SADS between the OAB group and non-OAB group were compared.The impacts of OAB on the anxiety level, quality of life, and social interaction were analyzed with multiple linear regression analysis. Results: The overall prevalence rate of OAB was 4.9% (244/5018).Multivariate logistic regression analysis showed that the history of urinary tract infection (OR=0.177), constipation (OR=0.636), smoking (OR=0.582), alcohol consumption (OR=0.685), coffee/strong tea drinking (OR=0.387), carbonated beverage drinking (OR=0.631), redundant prepuce (OR=0.673), phimosis (OR=0.311), urine holding (OR=0.593), and chronic insomnia (OR=0.256) were influencing factors for the occurrence of OAB (P＜0.05).The OAB group had higher SAS score [(41.18±6.54) vs. (38.61±6.36)], QoL score [(3.65±1.20) vs. (2.79±0.95)], social avoidance score [(6.25±1.86) vs. (5.86±1.51)], social distress score [(6.27±1.59) vs. (5.97±1.32)], and total SADS score [(12.51±2.35) vs. (11.84±2.01)] than the non-OAB group (P＜0.05).The results of multiple linear regression analysis showed that OAB could independently affect the scores of QoL, SAS, and SADS.The OAB group had higher scores of QoL, SAS, and SADS compared with the non-OAB group (P＜0.001). Conclusion: History of urinary tract infection, constipation, smoking, alcohol consumption, coffee/strong tea drinking, carbonated beverage drinking, redundant prepuce, phimosis, urine holding, and chronic insomnia are influencing factors for the occurrence of OAB in male college students.Moreover, OAB has negative impacts on their mental health, quality of life, and social interaction.

Objective:To explore the classification of bilobar anterolateral thigh perforator flaps assisted by color Doppler ultrasonography and its impact on their donor sites.Methods:A retrospective analysis was conducted of the data of 67 patients with large soft tissue defects who had been repaired with anterolateral thigh perforator flaps at Department of Orthopaedics, The Hospital Affiliated to The Second Medical University of Shandong, Department of Orthopaedics, The 80th Group Army Hospital of the People's Liberation Army, and Department of Orthopaedics, Weifang Traditional Chinese Medicine Hospital. The patients were divided into 2 groups according to their flaps used: a unilobar group and a bilobar group. In the unilobar group, 36 cases [25 males and 11 females with an age of (40.3±8.3) years] were repaired with a unilobar anterolateral thigh perforator flap from March 2015 to April 2019. In the bilobar group, 31 cases [22 males and 9 females with an age of (38.9±7.4) years] were repaired with a bilobar anterolateral thigh perforator flap from May 2019 to August 2023. Color Doppler ultrasonography was used to classify the bilobar flaps into 4 types according to the different distributions of perforating vessels: common trunk type, separate trunks type, fascia dependent type, and composite mixed type. The number of perforating vessels and type of perforator flap found by preoperative color Doppler ultrasound were compared with the intraoperative findings in the bilobar group. One year after operation, recovery rate of donor muscle strength, rate of skin paresthesia, scar length at the donor site, the widest scar width and motor function were compared between the 2 groups.Results:The number of perforating vessels and type of perforator flap found by preoperative color Doppler ultrasound were consistent with the intraoperative findings ( P<0.05). There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). One year after operation in the bilobar group, the recovery rate of donor muscle strength was 96.8% (30/31), significantly higher than that in the unilobar group [77.8% (28/36)], the rate of skin paresthesia 6.5% (2/31), significantly lower than that in the unilobar group [27.8% (10/36)], the scar length at the donor site (22.18±5.02) cm, significantly longer than that in unilobar group [(17.35±3.11) cm], the widest scar width (7.26±1.58) mm, significantly narrower than that in the unilobar group [(43.72±9.81) mm], and the scores of Vancouver Scar Assessment Scale and Fugl-Meyer lower limb motor function scale were (1.95±0.57) points and (8.39±2.17) points, respectively, significantly lower than those in the unilobar group [(6.38±1.72) points and (14.02±3.54) points] ( P<0.05). Conclusions:Preoperative classification of bilobar anterolateral thigh perforator flaps assisted by color Doppler ultrasonography may provide guidance for flap harvesting and lobe layout of the flap. Compared to traditional unilobar flaps, bilobar ones may minimize tissue damage at a donor site.
