ObjectiveTo investigate the triglyceride-glucose (TyG) index and the level of serum homocysteine (Hcy) in association with the incidence of stroke in type 2 diabetes mellitus (T2DM) patients. MethodsBased on the chronic disease risk factor surveillance cohort in Pudong New Area, Shanghai, excluding those with stroke in baseline survey, T2DM patients who joined the cohort from January 2016 to October 2020 were selected as the research subjects. During the follow-up period, a total of 318 new-onset ischemic stroke patients were selected as the case group, and a total of 318 individuals matched by gender without stroke were selected as the control group. The Cox proportional hazards regression model was used to adjust for confounding factors and explore the serum TyG index and the Hcy biochemical indicator in association with the risk of stroke. ResultsThe Cox proportional hazards regression results showed that after adjusting for confounding factors, the risk of stroke in T2DM patients with 10 μmol·L⁻¹-¹ and Hcy>15 μmol·L⁻¹ was 1.532 times (95%CI: 1.017‒2.309 times, P=0.041) and 1.738 times (95%CI: 1.119‒2.699 times, P=0.014) higher respectively, compared to T2DM patients with Hcy≤10 μmol·L⁻¹. T2DM patients with TyG>9.074 had 1.396 times higher risk of stroke (95%CI: 1.091‒1.787, P=0.008) compared to those with TyG≤9.074. The study found that urea and α1-antitrypsin (α1-AT) were independent risk factors for the incidence of stroke in T2DM patients. For every unit increase in urea andα1-AT, the risk of stroke in T2DM patients increased by 233.6% (HR=3.336, 95%CI: 1.588‒7.009, P=0.001) and 11.3% (HR=1.113, 95%CI: 1.028‒1.205, P=0.008), respectively. Cumulative risk curves showed that Hcy>10 μmol·L⁻¹ and TyG>9.074 accelerated the time to stroke occurrence in T2DM patients. ConclusionElevated levels of Hcy>10 μmol·L⁻¹ and a higher TyG index are risk factors for stroke in T2DM patients. Effective interventions for Hcy and TyG should be conducted for diabetic patients to reduce the incidence of stroke.

The Chinese version of the PAHLS included 6 items, and the results of item analysis showed that the content of each item was highly consistent with that of overall scale. The content validity indexes of the Chinese version of PAHLS at both the scale level and item level were 1. Only one factor was extracted based on exploratory factor analysis, with a cumulative variance contribution rate of 72.24%. Confirmatory factor analysis indicated a good fit, with the fitting indexes of χ2/ df=0.53, root mean square error of approximation (RMSEA)<0.01, root of mean square residual (RMR)=0.02, goodness-of-fit index (GFI)=1.00, comparative fit index (CFI)=1.00, normed fit index (NFI)=1.00, adjust goodness-of-fit index (AGFI)=0.98, incremental fit index (IFI)=1.00, Tucker-Lewis index (TLI)=1.01, Convergent validity: composite reliability (CR)=0.86 and average vriance extracted (AVE)=0.53. The overall Cronbach′s α coefficient of the scale was 0.91 and Cronbach′s α coefficients of item level were from 0.87 to 0.91, with split-half reliability value of 0.89. Conclusions:The Chinese version of the PAHLS has good reliability and validity, which can be used by medical staff to evaluate the propensity to achieve healthy lifestyle in hypertensive patients under Chinese cultural background, to increase understanding of decision-making on behavioral change in hypertensive patients and promote medical staff to jointly develop behavioral change plans with hypertensive patients.

Objective To observe the value of multiparametric MRI-based radiomics model and deep learning(DL)model for distinguishing benign and malignant myxoid soft tissue tumors(MSTT).Methods A total of 141 MSTT patients confirmed with pathology were retrospectively collected.The patients were randomly divided into training set(n=98,including 51 cases of malignant MSTT and 47 cases of benign MSTT)and test set(n=43,including 22 cases of malignant MSTT and 21 cases of benign MSTT)at the ratio of 7∶3.Based on T1WI and fat suppression(FS)-T2WI in training set,radiomics features and DL features were extracted and selected,then a radiomics model and a DL model were constructed,respectively.Receiver operating characteristic(ROC)curves,calibration curves and decision curves were drawn,and the discrimination,calibration and net benefit of these 2 models were compared.Results In training set,the radiomics model for differentiating benign and malignant MSTT was constructed according to 9 optimal radiomics features,including 2 first order features,1 shape feature,3 gray level co-occurrence matrix features,1 gray level dependence matrix feature and 2 gray level size zone matrix features,while DL model was built based on 7 optimal DL features.In test set,the area under the ROC curve of radiomics model and DL model was 0.758 and 0.911,respectively,the latter was higher than the former(P=0.017).Both models had good calibration,and DL model had higher overall net benefit.Conclusion Compared with radiomics model,DL model based on MRI had better ability to differentiating benign and malignant MSTT,also higher overall net benefit.

Objective To assess the safety of femoral artery puncture procedures guided by X-ray and ultrasound among elderly patients.Methods A total of 480 patients undergoing transcatheter interventional treatment for cardiovascular and cerebrovascular diseases through the femoral ar-tery in our hospital between January 2016 and December 2022 were enrolled in the study.Of them,326 patients receiving femoral artery puncture guided by X-ray fluoroscopy were assigned into X-ray group,while the other 154 patients guided by vascular Doppler ultrasound were into ultrasound group.With propensity score matching(PSM)in a ratio of 1∶1,finally 270 patients were included.Their general clinical data,success rate of puncture,puncture site,and incidence of vascular complications were compared between the two groups.Multivariate logistic regression analysis was used to identify the risk factors for vascular complications.Results Before PSM,there were no statistical differences in the mean distance from the skin fold to the bifurcation of the common femoral artery(2.5±1.0 cm vs 2.4±0.8 cm)or the distance from the fold to the in-guinal ligament(6.4±1.4 cm vs 6.3±1.7 cm)between the X-ray group and the ultrasound group(P＞0.05).After PSM,the X-ray group exhibited an obviously higher incidence of puncture points below the common femoral artery than the ultrasound group(14.8％vs 6.7％,P＜0.05),but no significant differences were observed in the one-time success rate of puncture or the occur-rence of vascular complications between the two groups(P＞0.05).Multivariate logistic regres-sion analysis indicated that the presences of non-common femoral artery and femoral artery calci-fication at the puncture site was independent risk factors for vascular complications(OR=8.379,95％CI:3.561-19.717;OR=3.922,95％CI:1.664-9.242).Conclusion There is no statistical disparity in safety between X-ray-versus ultrasound-guided femoral artery puncture procedures.Cli-nicians should choose appropriate puncture procedure or combine them together based on individual con-dition of patients.

Objective:To analyze the relationship between CT attenuation value of pulmonary artery thrombi and the efficacy of interventional thrombolysis in patients with acute pulmonary embolism (APE).Methods:This was a single center cross-sectional study. The clinical and imaging data of 89 APE patients who underwent interventional thrombolysis in Affiliated Hospital of Xuzhou Medical University from January 2018 to December 2022, were retrospectively analyzed. All patients underwent CT pulmonary angiography (CTPA) before and after thrombolysis, the CT attenuation value of pulmonary artery thrombi and ratio of CT attenuation value of thrombi to left subscapularis muscle CT value were obtained; and the difference of Qanadli embolism index (ΔQ) before and after thrombolysis was calculated. According to the median ΔQ, patients were classified as good efficacy group (ΔQ>50%) and poor efficacy group (ΔQ≤50%). The clinical characteristics and quantitative parameters of CT were compared between the two groups, and the factors associated with efficacy of thrombolysis were analyzed with univariate and multivariate logistic regression. The correlation between CT attenuation value of pulmonary artery thrombi and ΔQ was analyzed by Spearman correlation analysis.Results:The CT attenuation value of thrombi and ratio of attenuation value of thrombi to left subscapularis muscle CT value showed significant difference between the two groups ( P<0.05). Multivariate analysis showed that compared with CT attenuation value of emboli≤53.47 HU, the value>53.47 HU might be associated with the good efficacy of thrombosysis ( OR=9.175, 95% CI: 0.937-89.846, P=0.057). There was a positive correlation between CT value of pulmonary artery thrombi and ΔQ ( r=0.365, P<0.001). Conclusion:The CT attenuation value of thrombi can predict the efficacy of interventional thrombolysis in APE patients, and patients with higher CT attenuation value would have a better treatment response.

Objective:To compare the differences in radiation dose and image quality between cone-beam CT (CBCT) and multi-slice spiral CT (MSCT) applied to atlantoaxial spine imaging.Methods:Head and neck phantom was scanned at 30 exposure parameter combinations using Pramerica CBCT scanner and 15 parameter combinations using Toshiba 320-row MSCT. The effective dose ( E) of CBCT was calculated based on the Monte Carlo dose estimation software PCXMC, the E value of MSCT was obtained by multiplying the dose length product (DLP) by the related factor. t-test for two independent samples or Wilcoxon rank sum test were used for comparison of radiation dose and subjective and objective image quality between two modalities. The subjective evaluation was a 5-point subjective scale using double-blind method for edge sharpness, contrast, soft tissue level, and artifacts of the images. The signal and noise in the region of interest (ROI) were measured and the contrast signal-to-noise ratio (CNR) was calculated. Results:For radiation dose, the volumetric dose index and E values of 2.9 mGy and 27.61 μSv for CBCT were lower than those of 8.8 mGy and 433.16 μSv for MSCT, and the differences were statistically significant( z=-3.05, -5.25, P<0.05). For objective evaluation of image quality, the noise and CNR were 27.74 HU and 3.69 in CBCT group, 7.84 HU and 27.1 in MSCT group. The difference between them were statistically significant( z=-5.39, -5.42, P<0.05). The overall image quality, contrast and artifact scores of the CBCT group were 3.5, 3.0 and 5 were higher than those of the MSCT group at 2.0, 2.0, and 4.0, respectively ( z=-2.32, -2.46, -3.31, P<0.05). Conclusions:Both atlantoaxial CBCT and MSCT scans provide image quality that meets diagnostic requirements. Compared to MSCT, CBCT atlantoaxial scans can effectively reduce radiation dose according to the principle of optimization of radiation protection.

Diabetic kidney disease is one of the complications of diabetes,which can progress to end-stage renal disease.In recent years,it has been found that miRNAs have become a research hotspot,with miRNA-21 regulating transforming growth factor β1(TGF-β1)/Smads,phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT),Wnt/β-catenin and other signaling pathways to promote the progress of diabetic kidney disease.Studies have showed that traditional Chinese medicine has a regulatory effect on the expression of miRNA-21 and can target miRNA-21 to regulate TGF-β1/Smads,phosphatase and tensin homolog/PI3K/AKT/mammalian target of rapamycin(mTOR),peroxisome proliferator activated receptors and other signal transduction pathways to trigger signal cascade reactions,which intervene in pathological processes such as fibrosis,inflammation,oxidative stress and autophagy.In this article,the role of miRNA-21 in diabetic kidney disease and the intervention of traditional Chinese medicine were summarized,in order to provide some reference for the treatment of diabetic kidney disease and the development of new drugs.
