Objective To evaluate the effectiveness of Chronic Care Model in hypertension management in community health services.Methods Three hundred patients diagnosed with hypertension participated in this study and were divided into intervention and control groups.In the following 9 months,intervention measures based on the Chronic Care Model were delivered to intervention group,while the conventional measures to control group.Data collected before and after the intervention were analyzed uuing descriptive statistics,t-test,x2-test and analysis of covariance by SPSS16.0 for Windows.Results The intervention group had statistically significant positive effectiveness in drinking habit,daily salt intake(decreased 0.78g),diastolic blood pressure (decreased 2mmHg),BMI(decreased 0.4) and SF-36 physical component summary score(decreased 1.7)(P＜0.05).The intervention group had better improvement in BMI and SF-36 physical component summry score than the control group.Conclusion The health outcomes of patients with hypertension could be improved by applying the Chronic Care Model featured diet,exercise habits and other health related factors management.

Objective To explore the clinical significance of second transurethral resection (TUR) in patients with T1 urothelial cell carcinoma of the bladder.Methods The 142 cases with urothelial carcinoma were recruited.All patients underwent transurethral resection of bladder tumor (TURBT) and were diagnosed as stage T1 urothelial carcinoma of the bladder.The 68 of 142 cases underwent second TUR after the initial surgery.Tumor recurrence rate,progression rate and recurrence-free survival were compared.Results There were no statistical differences in age,gender,follow-up time,number of tumors,size of tumors or grade of tumors between patients with and without second TUR.Of the 68 cases that underwent second TUR,25 cases (36.8%) had residual tumor and 6 of them (8.8%) had muscle-invasive bladder cancer.After an average observation for 26.8 months,patients who underwent second TUR showed lower recurrence rate,higher recurrence-free rate and longer recurrence-free survival than patients without second TUR [37.1% vs.58.1%,x2=5.962,P=0.015;41% vs.35.1%,x2=8.502,P=0.004;21 months vs.12 months,U= 1584,P= 0.002].While the progression rate showed no statistical difference between them (14.5% vs.25.7%,x2 =2.570,P=0.109).Conclusions Second TUR provides an effective way to completely excise tumor.Second TUR is beneficial to the decrease of recurrence rate and improvement of recurrence-free survival.However,its effect on tumor progression needs further discussion.

ObjectiveTo evaluate the clinical effecacy and safety of transurethral enucleation of submucosal bladder leiomyoma.MethodsAnalyze retrospectively the clinical data of 6 patients (2 male,4 female) of submucosal bladder leiomyoma. The mean age was 59 years (range 32- 78). The clinical manifestations included dysuresia in 3 cases, irritative bladder in 1 case, gross hematuria in 1 caes, and no clinical symptoms in 1 case. The mean course was 23 months (range 1 week-4 years). All the bladder tumors were indicated by ultrasonography, CT scan and cystoscopy, while 4 cases of bladder filling defects were showed by intravenous urogram. Before the tranaurethral enucleation of the bladder tumor, a deep needle biopsy and pathological examination were carried out to confirm the diagnosis of bladder leiomyoma. For the relatively small lateral leiomyomas, holium laser enucleation was carried out, while for the big ones, resectoscope enucleation was used to remove the mass. Biopsys were performed after complete removal of the tumor.ResultsTransurethral enucleation of 6 cases of submucosal bladder tumors were successful without any postoperative complication. All patients regained normal urination, and lower urinary tract irritation was relieved obviously and hematuria disappeared. No tumor recurrence or metastasis was found during the follow-up of 4 to 158 months.ConclusionsCystoscopy and transurethral biopsy are the most important methods for the diagnosis of submucosal bladder leiomyoma. The transurethral enucleation is a feasible and safe surgical technique for such patients with excellent results.

Objective: To develop a model incorporating radiomic features and clinical factors to accurately predict acute ischemic stroke (AIS) outcomes. Materials and Methods: Data from 522 AIS patients (382 male [73.2%]; mean age ± standard deviation, 58.9 ± 11.5 years) were randomly divided into the training (n = 311) and validation cohorts (n = 211). According to the modified Rankin Scale (mRS) at 6 months after hospital discharge, prognosis was dichotomized into good (mRS ≤ 2) and poor (mRS > 2); 1310 radiomics features were extracted from diffusion-weighted imaging and apparent diffusion coefficient maps. The minimum redundancy maximum relevance algorithm and the least absolute shrinkage and selection operator logistic regression method were implemented to select the features and establish a radiomics model. Univariable and multivariable logistic regression analyses were performed to identify the clinical factors and construct a clinical model. Ultimately, a multivariable logistic regression analysis incorporating independent clinical factors and radiomics score was implemented to establish the final combined prediction model using a backward step-down selection procedure, and a clinical-radiomics nomogram was developed. The models were evaluated using calibration, receiver operating characteristic (ROC), and decision curve analyses. Results: Age, sex, stroke history, diabetes, baseline mRS, baseline National Institutes of Health Stroke Scale score, and radiomics score were independent predictors of AIS outcomes. The area under the ROC curve of the clinical-radiomics model was 0.868 (95% confidence interval, 0.825–0.910) in the training cohort and 0.890 (0.844–0.936) in the validation cohort, which was significantly larger than that of the clinical or radiomics models. The clinical radiomics nomogram was well calibrated (p > 0.05). The decision curve analysis indicated its clinical usefulness. Conclusion The clinical-radiomics model outperformed individual clinical or radiomics models and achieved satisfactory performance in predicting AIS outcomes.
