Objective To explore the causal relationship between immune cells and heart failure (HF), and the mediating role of serum metabolites, in order to identify potential biomarkers and therapeutic targets. Methods We employed a two-sample Mendelian randomization (MR) analysis method based on genome-wide association study (GWAS) data, analyzing the direct and indirect effects of 731 types of immune cells and 1 400 metabolites on HF. We selected valid instrumental variables and conducted statistical analyses using R software. The primary analysis was performed using the inverse variance weighted method, supplemented by MR-Egger analysis and weighted median method. The stability of the results was assessed through tests such as Cochran’s Q test. Results Our research found a negative causal relationship between PD-L1 on CD14−CD16+ and HF. Sensitivity analysis supported this result. The reverse MR analysis did not find an effect of HF on PD-L1 on CD14−CD16+, indicating that PD-L1 on CD14−CD16+ might play a unidirectional role in reducing the risk of HF. Further mediation MR analysis showed that PD-L1 on CD14−CD16+ might influence the risk of HF onset by regulating the levels of sphingomyelin (d17:1/14:0, d16:1/15:0), with a mediation effect ratio of 6.7%. Conclusion PD-L1 on CD14−CD16+ may reduce the risk of HF by elevating the levels of sphingomyelin (d17:1/14:0, d16:1/15:0), which provides a new perspective for understanding the pathogenesis of HF.

Objective: To explore the effect of different obesity indicators in predicting cardiovascular and cerebrovascular diseases (CVD) risk among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for the early identification of CVD risk among T2DM patients. Methods: The patients with T2DM under community management in Qingpu District, Shanghai Municipality were selected as the study subjects in January 2025. Basic information such as gender, age, and blood glucose control status were collected through the Shanghai Chronic Disease Information Management System, while history of CVD were obtained from residents' electronic health records and the Shanghai Disease Control Information Platform. Obesity was assessed using body mass index (BMI), waist circumference (WC), BMI combined with WC, waist-to-height ratio (WHtR), and triglyceride (TG) combined with WC indicators. The association between obesity and CVD was analyzed using multivariable logistic regression models. The predictive effect of each obesity indicators for CVD was evaluated using the area under the receiver operating characteristic curve (AUC). Results: A total of 4 367 patients with T2DM were included, including 2 121 males (48.57%) and 2 246 females (51.43%). The average age was (68.71±8.05) years. The prevalence of CVD was 44.49%. Multivariable logistic regression analysis showed that after adjusting for age, education level, history of hypertension, duration of T2DM, use of glucose-lowering medications, renal function, and blood glucose control status, obese T2DM patients had a 389.4% increased risk of CVD compared to those with normal BMI; centrally obese T2DM patients had a 100.4% increased risk compared to those with normal WC; T2DM patients with isolated general obesity and compound obesity had 161.0% and 241.1% increased risks of CVD, respectively, compared to those with normal BMI and WC; centrally obese T2DM patients had a 100.4% increased risk compared to those with normal WHtR; T2DM patients with normal TG-high WC and high TG-high WC phenotypes had 83.1% and 68.8% increased risks of CVD, respectively, compared to those with normal TG and normal WC (all P<0.05). BMI had the highest AUC, at 0.714, with sensitivity and specificity of 0.675 and 0.642, respectively. This was followed by BMI combined with WC, which had an AUC of 0.707, with sensitivity and specificity of 0.635 and 0.679, respectively. Conclusions Obesity defined by BMI, WC, BMI combined with WC, WHtR, and TG combined with WC increases the risk of CVD among patients with T2DM. BMI and BMI combined with WC have better predictive effect in predicting CVD risk among patients with T2DM, and can be used as the primary obesity indicators for CVD risk screening.

AIM: To prepare radix scutellariae microemulsion gel and investigate its therapeutic effect on chronic eczema based on the previous research of radix scutellariae self microemulsion. METHODS: The gel matrix and humectant were optimized by single factor method and response surface method to obtain the formula and preparation technique of the gel. The Franz diffusion cell method was used to evaluate the transdermal properties of microemulsion and microemulsion gel in vitro. By establishing a chronic eczema model in the mouse ear, the swelling degree, swelling inhibition rate, pathological changes and tumor necrosis factor α (TNF-α), Interleukin-1β (IL-1β) and interleukin - 6 (IL-6) of radix scutellariae microemulsion gel were measured, to investigate the therapeutic effect on chronic eczema in mice. RESULTS: The physical and chemical properties of radix scutellariae microemulsion gel were stable. Compared with microemulsion, the microemulsion gel had better transdermal performance. The cumulative transdermal amount of baicalein and wogonin, the main components of microemulsion gel, was 1.85 times and 2.77 times of that of microemulsion respectively. Moreover, the steady flow rate and permeability coefficient of microemulsion gel significantly increased, and the lag time significantly shortened. Pharmacodynamic study showed that compared with the model group, the radix scutellariae microemulsion gel could significantly reduce the ear swelling of mice (P<0.05), and the serum inflammatory factor TNF - α, IL-1β and IL-6 reduced content by over 37%. Compared with the radix scutellaria aqueous extract and aqueous extract gel, the treatment of chronic eczema was better. CONCLUSION: The preparation process of radix scutellaria microemulsion gel is feasible, with strong transdermal property, and a significant therapeutic effect on chronic eczema.

Objective To investigate the clinical application of three-dimensional intracavitary/free-hand interstitial brachytherapy technique in radical radiotherapy for cervical cancer. Methods A retrospective study was conducted on the clinical data of patients with cervical cancer who underwent radical radiotherapy using CT-guided three-dimensional intracavitary/free-hand interstitial brachytherapy technique in The Affiliated Cancer Hospital of Nanjing Medical University from April 2019 to September 2021. The short-term efficacy and adverse reactions were analyzed, and the independent predictors affecting short-term efficacy were evaluated by logistic risk regression model. Results A total of 182 patients were included, and all patients successfully completed the treatment. Clinical efficacy assessment performed 3 months after treatment revealed an overall response rate of 90.65%; the incidence of grade 3 and 4 adverse reactions in the lower gastrointestinal tract was 4.4% during treatment. After reclassifying stage IIIC patients according to the International Federation of Gynecology and Obstetrics (FIGO) 2009 staging system and including factors affecting the stage, it was found that the tumor volume before brachytherapy was the main factor affecting the clinical efficacy of patients at this stage (P = 0.004). Conclusion As a key method in radical radiotherapy for cervical cancer, three-dimensional intracavitary/free-hand interstitial brachytherapy technique is safe and effective and can be quickly popularized in primary hospitals beyond regional cancer centers for cervical cancer brachytherapy.

Objective To understand the characteristics and temporal trends of stroke incidence in the household population of Shanghai's Qingpu District and to provide a basis for the development of comprehensive prevention and control strategies. Methods The stroke case database for Qingpu District from 2017-2022 was obtained from the Shanghai Stroke and Acute Myocardial Infarction Registry and Reporting Information System. The average age of onset, incidence rate, standardised incidence rate, and constitutive ratio were calculated. Independent samples t-tests were used for comparisons between groups, 2-tests and 2-trend tests for comparisons of rates, and the Joinpoint regression model for calculating the annual percentage change (APC) to analyse the temporal trend of rates. Results Between 2017 and 2022, the average age of stroke onset in the household population of Shanghai's Qingpu District was 73.69±11.60 years. The average annual incidence rate was 556.62/100 000, with an average annual standardised incidence rate of 333.76/100000. There was an increasing trend in the incidence and standardised incidence of stroke in males (APC=7.06%, t=3.44, P=0.03, APC=5.32%, t=3.04, P=0.04). The incidence of stroke increases with age, with cases mainly concentrated in those aged 65 years and above, accounting for 79.47%. Ischemic stroke dominates the stroke typology, accounting for 91.08% of cases, while the incidence of hemorrhagic stroke shows an increasing trend (APC=4.64%, t=4.59, P=0.01). Conclusion The occurrence of stroke in the general population of Shanghai’s Qingpu District is concerning. The study indicates that males, individuals aged 65 years and above, and ischaemic stroke are significant factors that require attention for stroke prevention and control.
