Objective:To investigate associations between cardiac biomarkers with stroke severity and short-term outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Qingdao University from June 2018 to February 2024 whose etiological classification was large artery atherosclerosis (LAA), small vessel occlusion (SVO) or cardioembolism (CE) were included retrospectively. According to the National Institutes of Health Stroke Scale score at admission, patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8). According to the modified Rankin Scale score at discharge, patients were divided into good outcome group (≤2) and poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent correlation between cardiac biomarkers and short-term outcome. The predictive value of cardiac biomarkers for poor outcome in patients with AIS and different stroke etiology subtypes were evaluated using receiver operating characteristic (ROC) curves. Results:A total of 2 151 patients with AIS were enrolled, including 1 256 males (58.4%), aged 67.40±11.34 years. 1 079 patents were LAA type (50.2%), 679 were SVO type (31.6%), and 393 were CE type (18.3%); 1 223 were mild stroke (56.86%) and 928 (43.14%) were moderate to severe stroke; 1 357 patients (63.09%) had good short-term outcome, and 794 (36.91%) had poor short-term outcome. Multivariate logistic regression analysis showed that N-terminal pro-B type natriuretic peptide (NT-proBNP), NT-proBNP/creatine kinase (CK) isoenzyme MB (CK-MB) ratio, and CK-MB/CK ratio were independent risk factors for poor short-term outcome. ROC curve analysis shows that the CK-MB/CK ratio had a higher predictive value for short-term poor outcome in patients with AIS (the area under the curve, 0.859, 95% confidence interval 0.839-0.879). Various cardiac biomarkers had a higher predictive value for short-term outcome of CE type and LAA type, but the predictive value for short-term outcome of SVO type was lower. Conclusions:Cardiac biomarkers are associated with the severity and poor outcome of AIS. NT-proBNP/CK-MB and CK-MB/CK ratios have higher predictive value for short-term poor outcome of AIS, especially in patients with CE type.

Objective To analyze the influence of medication compliance of chronic type 2 diabetes management patients on disease control in two communities in Kunming.Methods A total of 138 patients with type 2 diabetes who were included in chronic disease management in Guandu and Xiaobanqiao communities of Kunming were selected from December 2021 to September 2022.Basic information collection and HbAlc and other related tests were improved.A questionnaire survey of 8-item Morisliy medication adherence scale(MMAS-8)was conducted to analyze the levels of HbAlc and other indexes of three groups with high(group A),medium(group B),and low(group C)adherence,and to conduct statistical analysis.Results Group A accounted for 22.5%,group B for 44.9%,and group C for 32.6%.There were significance differences in urinary albumin creatinine ratio(UACR),HbA1c and blood creatinine among the three groups(P<0.05).The levels of UACR,HbAlc and serum creatinine in group A were lower than those in group B and group C,and there was a negative correlation between UACR,HbAlc and serum creatinine and medication compliance rate(P<0.05).Conclusion In the Guandu Community and Xiaobanqiao community of Kunming,only 22.5%of patients with chronic type 2 diabetes had high medication compliance.The higher the compliance,the lower the level of UACR,HbAlc and serum creatinine,there is a correlation between the two,suggesting that medication compliance should be regarded as one of the key points in the management of chronic diabetes mellitus in the community,and the intervention of patients'medication compliance should be strengthened.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate the value of T2 mapping sequence combined with apparent diffusion coefficient(ADC)values in identifying benign and malignant breast lesions.Methods Ninety-two patients with breast mass were retrospectively selected,all patients received MRI examination,T2 mapping sequence and ADC values were selected for image analysis,and all patients underwent surgical biopsy and pathological diagnosis,the clinical value of T2 mapping sequence combined with ADC values in differential diagnosis of benign and malignant breast lesions was observed.Results After pathological examination,52 patients were diagnosed as malignant breast lesions and the remaining 40 were diagnosed as benign breast lesions.Among 52 patients with malignant lesions,51 were diag-nosed as malignant and 1 was diagnosed as benign by ADC values.Among the 40 cases of benign lesions,16 were diagnosed as malig-nant and 24 were diagnosed as benign by ADC values.The difference between the mean T2 values of benign breast lesions and malig-nant breast lesions was not significant(P＞0.05);but the coefficient of variation(CV)of T2 values of malignant breast lesions was significantly higher than that of benign breast lesions,and the difference was significant(P＜0.05),and the diagnostic efficacy of T2 mapping and ADC value single examination was lower than that of the combined examination(P＜0.05).Conclusion T2 mapping sequence and ADC value in MRI have the ability to diagnose and distinguish benign and malignant breast,especially the value of the joint application of the two is more prominent,improve the diagnostic accuracy,sensitivity and specificity,and can provide more accurate reference information for clinical practice,which is worth popularizing.

Microwave thermotherapy(MWTT),as a treatment for tumors,lacks specificity and requires sensitizers.Most reported microwave sensitizers are single metal-organic frameworks(MOFs),which must be loaded with ionic liquids to enhance the performance in MWTT.Meanwhile,MWTT is rarely combined with other treatment modalities.Here,we synthesized a novel Fe-Cu bimetallic organic framework FeCuMOF(FCM)by applying a hydrothermal method and further modified it with methyl polyethylene glycol(mPEG).The obtained FCM@PEG(FCMP)showed remarkable heating performance under low-power microwave irradiation;it also acted as a novel nanospheres enzyme to catalyze H2O2 decompo-sition,producing abundant reactive oxygen species(ROS)to deplete glutathione(GSH)and prevent ROS clearance from tumor cells during chemodynamic treatment.The FCMP was biodegradable and demonstrated excellent biocompatibility,allowing it to be readily metabolized without causing toxic effects.Finally,it was shown to act as a suitable agent for T2 magnetic resonance imaging(MRI)in vitro and in vivo.This new bimetallic nanostructure could successfully realize two tumor treatment modalities(MWTTand chemodynamic therapy)and dual imaging modes(T2 MRI and microwave thermal imaging).Our findings represent a breakthrough for integrating the diagnosis and treatment of tumors and pro-vides a reference for developing new microwave sensitizers.

Irritable bowel syndrome (IBS) is considered a stress disorder characterized by psychological and gastrointestinal dysfunction. IBS patients not only suffer from intestinal symptoms such as abdominal pain, diarrhea, or constipation but also, experience dysthymic disorders such as anxiety and depression. Studies have found that corticotropin-releasing hormone plays a key role in IBS with comorbid dysthymic disorders. Next, we will summarize the effects of corticotropinreleasing hormone from the central nervous system and periphery on IBS with comorbid dysthymic disorders and relevant treatments based on published literatures in recent years.

Objective To investigate the diagnostic value of combining carotid intima-media thickness (cIMT) with serum Galectin-3 (Gal-3) and Pentraxin 3 (PTX3) in patients with psoriasis complicated with cardiovascular disease (CVD). Methods Thirty-eight patients with psoriasis complicated with CVD were included in CVD group, 51 patients with psoriasis alone were included in psoriasis group, and 60 healthy subjects were selected as control group. Clinical data were collected from each group. The cIMT was measured using carotid ultrasound, and serum Gal-3, PTX3, and inflammatory markers[high sensitivity C-reactive protein (hs-CRP), procalcitonin (PCT), tumor necrosis factor-α (TNF-α)]were detected using enzyme-linked immunosorbent assay. Multivariate Logistic regression analysis was used to identify the influencing factors of CVD in patients with psoriasis. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of serum Gal-3, PTX3, and cIMT for CVD. Results The cIMT was greater in the CVD group and the psoriasis group than in the control group, and the CVD group was greater than the psoriasis group (P < 0.05). The serum levels of Gal-3, PTX3, hs-CRP, PCT, and TNF-α were higher in the CVD group and the psoriasis group than in the control group, and their levels were higher in the CVD group than in the psoriasis group (P < 0.05). The psoriasis area and severity index (PASI) score was higher in the CVD group than in the psoriasis group (P < 0.05). Pearson's correlation analysis showed that cIMT, Gal-3, and PTX3 were separately positively correlated with hs-CRP, PCT, and TNF-α (P < 0.05). Multivariate Logistic regression analysis showed that PASI score, cIMT, Gal-3, PTX3, hs-CRP, and TNF-α were independent influencing factors for CVD in patients with psoriasis (OR=1.250, 1.451, 1.432, 1.365, 1.413, 1.465; P < 0.05). The diagnostic model based on cIMT combined with serum Gal-3 and PTX3 had higher diagnostic value for CVD in patients with psoriasis than single diagnosis. The area under the curve was 0.922, with sensitivity and specificity of 0.91 and 0.85, respectively. Conclusion The cIMT, serum Gal-3, and serum PTX3 are independent influencing factors for CVD in patients with psoriasis. The combination of the three indicators has higher diagnostic value for CVD in patients with psoriasis.
