Objective To compare and analyze the efficacy and safety of 5-needle injection and standard 20-needle injection in the treatment of overactive bladder with botulinum toxin type A.Methods A retrospective analysis was performed on 48 patients with overactive bladder who received intravesical injection of botulinum toxin type A in the Department of Urology,Hangzhou Third People's Hospital from January 2015 to December 2022,and they were divided into two groups according to the number of injections,with 24 patients in each group.The observation group received 5-needle injection,and the control group received standard 20-needle injection.Average daily frequency of urination,international consultation on incontinence questionnaire-overactive bladder,international consultation on incontinence questionnaire-overactive bladder(ICIQ-OAB)score,overactive bladder(OAB-Q)score,visual analogue scale(VAS),patient generated index(PGI-I)score,complication rate and willingness to repeat injection were recorded before and after treatment in two groups,respectively.Results There were no significant differences in age,gender,course of disease,average daily frequency of urination before treatment and baseline data of each score between the two groups,which were comparable.All patients completed treatment,and compared with before treatment,the mean daily frequency of urination,ICIQ-OAB and OAB-Q were improved after treatment(P<0.05),there was no significant difference between the two groups(P>0.05).There were no significant differences in scores and incidence of complications between the two groups after treatment(P>0.05).However,patients in the observation group were more willing to receive another injection(P<0.05).Conclusion The efficacy and safety of 5-needle vesical injection of botulinum toxin type A in the treatment of overactive bladder is similar to that of standard 20-needle injection,which is more easily accepted by patients,and is a safe and effective alternative to standard technique.

Objective: Recent studies indicate that 3 morphological types of atlanto-occipital joint (AOJ) exist in the craniovertebral junction and are associated with type II basilar invagination (BI) and atlanto-occipital instability. However, the actual biomechanical effects remain unclear. This study aims to investigate biomechanical differences among AOJ types I, II, and III, and provide further evidence of atlanto-occipital instability in type II BI. Methods: Models of bilateral AOJ containing various AOJ types were created, including I-I, I-II, II-II, II-III, and III-III models, with increasing AOJ dysplasia across models. Then, 1.5 Nm torque simulated cervical motions. The range of motion (ROM), ligament and joint stress, and basion-dental interval (BDI) were analyzed. Results: The C0–1 ROM and accompanying rotational ROM increased progressively from model I-I to model III-III, with the ROM of model III-III showing increases between 27.3% and 123.8% indicating ultra-mobility and instability. In contrast, the C1–2 ROM changes were minimal. Meanwhile, the stress distribution pattern was disrupted; in particular, the C1 superior facet stress was concentrated centrally and decreased substantially across the models. The stress on the C0–1 capsule ligament decreased during cervical flexion and increased during bending and rotating loading. In addition, BDI gradually decreased across the models. Further analysis revealed that the dens showed an increase of 110.1% superiorly and 11.4% posteriorly, indicating an increased risk of spinal cord impingement. Conclusion Progressive AOJ incongruity critically disrupts supportive tissue loading, enabling incremental atlanto-occipital instability. AOJ dysplasia plays a key biomechanical role in the pathogenesis of type II BI.

Objective To establish a simple model for arteriosclerosis(AS)screening to provide a viable tool for the timely identification of AS risk among residents aged 40～65 years.Methods Data were obtained from the Sleep and Chronic Diseases Program in Fuquan City.The original dataset was divided into a training subset and a validation subset(80%:20%).LASSO and logistic regression models were used to screen variables,perform multivariate regression analyses.Internal validation was performed using the Bootstrap method.Nomogram Plot was constructed,and risk score thresholds were determined based on ROC curves to classify high-risk populations.Results RS Model was established to include age,gender,napping,sleep efficiency,sleep disorders,hyperten-sion and diabetes,with AUC=74.80%and a model risk score threshold=84.20.PHC Model was established to include age,gender,napping,sleep efficiency,systolic blood pressure,fasting blood glucose,and pulse variables,with AUC=82.80%and a risk score threshold of 78.00.Decision curves showed that both models performed well in terms of calibration and actual benefits for health management.Conclusion The two AS screening models exhibit acceptable accuracy and differentiation.Therefore,it can be applied in residents'self-health management and in primary care organizations'screening work in a large scale.

Objective:To analyze the association between body health score and the risk of hypertension among health examination population aged 40-65 years.Methods:This study was a cross-sectional study, and 1 104 people aged 40-65 years who underwent physical examination at the Physical Examination Centre of the First People′s Hospital of Fuquan City from March to November 2022 were selected. Clinical data, such as general information, physical examination, body composition and history of hypertension diseases, were collected. The body health score was reported by the Xiaomi Body Fat Scale′s accompanying exercise health software, and was calculated by combining body fat, water and other body composition data. The association between body health score and the risk of hypertension was analyzed using restricted cubic spline regression models, while a sensitivity analysis and sex-stratified analyses were performed. Multivariate logistic regression combined with stratified analysis was used to explore the association between dimensions of body composition and the risk of hypertension.Results:The body health score was significantly lower in hypertensive patients than in non-hypertensive patients among the 1 104 health examination population [52.0(30.0) vs 69.0(35.8) points] ( Z=-8.547, P<0.001). The lower the body health score, the higher the risk of hypertension ( χ2=18.48, PNonlinear<0.001). In the total population, high body mass index was associated with an increased risk of hypertension ( OR=1.744, 95% CI: 1.104-2.765), high protein content was associated with a reduced risk of hypertension ( OR=0.587, 95% CI: 0.344-0.982) (both P<0.05). Gender-stratified analyses showed that high protein content was associated with a reduced risk of hypertension only in men ( OR=0.233, 95% CI: 0.080-0.592) ( P=0.004). High body mass index was positively associated with the risk of hypertension when the body health score was ≥60 points ( OR=2.378, 95% CI: 1.255-4.542) ( P=0.008). High visceral adiposity index (VAI) was positively associated with the risk of hypertension when the body health score was <60 points ( OR=4.395, 95% CI: 1.466-13.620), and high protein content was negatively associated with the risk of hypertension ( OR=0.255, 95% CI: 0.091-0.638) (all P<0.05). Conclusions:Health examination population aged 40-65 years with lower scores of physical health are more likely to have a risk of hypertension. Men should pay attention to the impact of body protein in hypertension risk prevention and control. The effect of body mass index should be noted when body health scores are ≥60 points, and the effect of VAI and body protein should be considered when body health scores are <60 points.

Objective The DNA methylation microhaplotype(DMH)refers to the combination of multiple methylation sites within a very short range,and these haplotypes show wide diversity.We carried out screening and validation of age-related DMHs in mouse blood.Methods We initially constructed a theoretical dataset of DMHs based on the mouse reference genome.We then screened age-related DMHs by Spearman's rank correlation analysis,using high-throughput sequencing information for DNA methylation in mouse blood from a network database.Finally,cross-validation was performed using a validation dataset.Results A total of 6787 142 DMH sites were identified within 50 bp in the mouse genome,including 98.64%of single-digit CpG sites.A total of 5835 age-associated DMHs were screened in 58 mouse blood samples(|rho|＞0.5,P＜0.01),accounting for 0.086%of DMHs.Finally,we validated the top 100 age-associated DMHs with high correlation in 95 independent samples,Resultsing in 44 loci.Conclusions The age-associated DMHs screened in this study may be useful in future studies of apparent age prediction using mouse blood and in aging studies.

Objective To analyze the risk factors affecting the prognosis of patients with advanced gastric cancer,so as to provide evidence for identifying high-risk populations and guiding clinical treatment.Methods The clinical data of 282 patients with advanced gastric cancer who admitted to Zhoushan Hospital of Traditional Chinese Medicine from January 2017 to December 2021 were retrospectively analyzed.The survival outcome of patients was obtained by telephone follow-up and regular review.Kaplan-Meier method was used to analyze the overall survival(OS).Univariate and multivariate COX regression models were used to analyze the effects of clinical features on OS in patients with advanced gastric cancer.Results The median OS of 282 patients with advanced gastric cancer was 10.0 months.Univariate analysis showed that first-line chemotherapy,traditional Chinese medicine treatment,body mass index(BMI),Karnofsky performance status(KPS)score,hemoglobin(Hb)and albumin(Alb)were significantly correlated with the survival of patients with advanced gastric cancer(P<0.05).Multivariate COX regression models analysis showed that first-line chemotherapy,BMI,KPS score and Alb were independent risk factors affecting the survival of patients with advanced gastric cancer(P<0.05).Conclusion BMI,Alb,KPS score and first-line chemotherapy are independent risk factors for predicting the prognosis of patients with advanced gastric cancer,indicating nutrition management may be an important way to improve the outcome of patients with advanced gastric cancer.
