Objective To explore the predictive value of electroencephalograph(EEG)quantitative parameters combined with serum microRNAs(miR)-146a-5p in cognitive dysfunction in patients with Alzheimer's disease(AD).Methods A total of 96 AD patients diagnosed in Shaoxing Seventh People's Hospital from March 2022 to May 2024 were selected to assess whether the patients had cognitive impairment according to the Montreal cognitive scale(MoCA)score,and 40 patients with cognitive impairment were set as occurrence group(MoCA score＜26points).A total of 56 patients with normal cognitive function were set as non-developing group(MoCA score ≥ 26points).Quantitative electroencephalography(EEG)parameters and serum miR-146a-5p were compared between the two groups.The risk factors of cognitive dysfunction in AD patients were analyzed by Logistic regression,and receiver operating characteristic curve was used to predict efficacy of EEG quantitative parameters and serum miR-146a-5p on cognitive dysfunction in AD patients.Results The δ frequency band,θ frequency band,and serum miR-146a-5p levels were lower in occurrence group than those in non occurrence group,while β frequency band and α frequency band were higher in occurrence group than in those non occurrence group(P＜0.05).δ frequency band,θ frequency band,miR-146a-5p,age,and years of education were risk factors for cognitive dysfunction in AD patients(P＜0.05).The area under the curve(AUC)of predicting cognitive impairment in AD patients using the combination of δ frequency band,θ frequency band,βfrequency band,α frequency band,and miR-146a-5p was 0.908.The sensitivity of predicting cognitive impairment in AD patients using the combination of delta frequency band,δ frequency band,β frequency band,α frequency band,and miR-146a-5p was higher than that of individual detection(P＜0.05).Conclusion The decrease in δ frequency band,θ frequency band,serum miR-146a-5p,and the increase in β frequency band and α frequency are closely related to the occurrence of cognitive dysfunction in AD patients.Combined detection of EEG of electroencephalogram and serum miR-146a-5p can improve the predictive efficiency of cognitive dysfunction.

Endometriosis is a common estrogen-dependent disease in women of childbearing age,often leading to chronic pelvic pain,infertility,ovarian cancer,and other serious complications,and jeopardizing the health of women.The pathogenesis of endometriosis is complex and involves the alteration of multiple signaling pathways mediated by hormones,immunity,genetics,and the environment,and their interactions.Wnt/β-catenin signaling is involved in the regulation of embryonic development and tissue homeostasis,and it has recently been implicated in the pathogenesis of endometriosis via multiple pathways.This review considers the biological characteristics of the Wnt/β-catenin signaling pathway and summarizes the main mechanisms and signaling pathways involved in the pathogenesis of endometriosis,as well as the curr-ent research status of the regulation of this signaling pathway by traditional Chinese medicine for the treatment of endometriosis.We aim to clarify how the Wnt/β-catenin signaling pathway affects the development of endometriosis,and suggest that future studies should focus on exploring its potential role as an indicator for the clinical prediction and early diagnosis of endometriosis,thus providing theoretical support for the early diagnosis of this condition and the development of targeted drugs.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

Objective:To investigate the stability and feasibility of improved silent MRA technique based on hybrid-arterial spin labeling(ASL) for imaging intracranial arterial stenosis.Methods:From September 2019 to May 2020, totally 35 patients with suspected intracranial vascular stenosis in Department of Neurology of Northern Jiangsu People′s Hospital were enrolled in this study. Silent MRA and improved silent MRA based on hybrid-ASL technique were performed respectively. The acquisition noise (noise measurement and subjective score) of two kinds of MRA examination were evaluated respectively. Two neuroradiologists performed image quality scoring and signal-to-noise ratio (SNR) measurement of intracranial arteries (including internal carotid artery, vertebrobasilar artery, anterior cerebral artery, middle cerebral artery, and posterior cerebral artery) in the two kinds of MRA images using a double-blind, completely randomized method. Independent sample t-test was used to compare the image quality and SNR of two kinds of MRA images in each segment. Two experts assessed the degree of stenosis at the site of confirmed intracranial artery stenosis. Kappa test was used to assess interobserver and intermodel agreement. Results:There was no significant difference in acquisition noise between improved silent MRA and silent MRA ( P>0.05). In all five segments measured, the image quality scores of internal carotid artery [(4.40±0.49)scores], anterior cerebral artery[(4.30±0.33)scores] and middle cerebral artery [(4.46±0.34)scores] in improved silent MRA were higher than those in silent MRA images [(4.02±0.43)scores, (4.02±0.31)scores, (4.02±0.31)scores; t=2.825, 2.877, 1.683, all P<0.05)]. The SNR of internal carotid artery (9.11±1.23) and middle cerebral artery (8.77±1.87) in improved silent MRA images was higher than that in silent MRA images (7.83±1.33, 8.06±2.67, respectively; t=11.154, 3.268, both P<0.05). A total of 24 patients (38 lesions) with intracranial vascular stenosis were diagnosed by CTA. Improved silent MRA (Kappa=0.89, 95%CI 0.82-0.95) and silent MRA (Kappa=0.85, 95%CI 0.77-0.92) were highly consistent among observers in evaluating the degree of cerebrovascular stenosis.The results of improved silent MRA were highly consistent with those of CTA (Kappa=0.92, 95%CI 0.87-0.98), and those of silent MRA were highly consistent with those of CTA (Kappa=0.85, 95%CI 0.77-0.92). Conclusions:The improved silent MRA is feasible to improve the imaging quality and signal uniformity through efficient marking based on keeping the low noise features. In the diagnosis of intracranial stenosis and occlusive disease, the stability of improved silent MRA imaging improves the diagnostic efficiency of stenosis to a certain extent.

Objective To evaluate the predictive value of ultrasonography of the respiratory variability index of inferior vena cava internal diameter (IVC-RVI) in preoperative fluid responsiveness evaluation of hip fracture in geriatric patients.Methods A retrospective case-control study was used to analyze 39 cases of elderly hip fractures admitted to the Daping Hospital of Army Medical Center from August 2017 to February 2018,including 15 males and 24 females,aged 65-92 years [(80.9 ±7.9)years].The heart rate (HR),mean arterial pressure(MAP),cardiac output (CO),and cardiac stoke volume (SV)were recorded five minutes after the patient entered the operating room and within 5 minures after capacity load test.The inferior vena cave during expiration (IVCe) and inferior vena cave during inspiration (IVCi) were measured by ultrasound before and after volume load test and the difference in IVC-RVI was calculated.Volumetric positive group were the cases of SV change (△SV) ≥15％ (positive group,n =21),and volume negative group were the cases of △SV ＜ 15％ (negative group,n=18).The correlations between various ultrasonic parameters and SV were analyzed by comparing HR,MAP,CO,SV,SV,IVCe,IVCi and IVC-RVI before and after the capacity load test.The predictive value of IVC-RVI for preoperative volumetric reactivity in elderly patients with hip fractures was evaluated by using the receiver operative characteristic (ROC) curve and Pearson correlation analysis.Results Prior to the volumetric load test,no significant difference was observed between the two groups concerning HR,MAP,CO,SV,and IVCe (P ＞ 0.05),IVCi in the positive group was significantly smaller than that in the negative group (P ＜ 0.05),and IVC-RVI in the positive group was significantly larger than that in the negative group (P ＜ 0.05).After the volumetric load test,there was no statistically significant difference between the two groups in CO,IVCe,IVCi,and IVC-RVI (P ＞ 0.05),HR in the positive group was smaller than that in the negative group (P ＜ 0.05),and MAP and SV in the positive group were significantly larger than that in the negative group (P ＜ 0.05).Compared with that before capacity load test,MAP,CO,and SV in the positive group increased after the capacity load test (P ＜ 0.05),while the HR difference was not statistically significant (P ＞ 0.05).HR,MAP,CO,and SV showed no significant difference in the negative group before and after capacity test (P ＞ 0.05).IVC-RVI assessed the area under the curve (AUC) was 0.80 ± 0.08 for preoperative volumetric responsiveness in elderly hip fractures (P ＜ 0.05),with a critical point of 20.69％,sensitivity of 77.78％,and specificity of 76.19％.After Pearson correlation analysis,IVC-RVI was positively related to △SV (OR =0.367,P ＜ 0.05).Conclusion Ultrasonography of the respiratory variability of IVC can predict the preoperative fluid responsiveness of hip fracture in geriatric patients and guide for clinical rehydration.
