Objective To investigate the effects of different ratios of ω-3 polyunsaturated fatty acids(ω-3 PUFA)on depression and cognitive impairment in patients with major depression.Methods A randomized,double-blinded controlled trial was used to randomly assign patients with depression to a cognitive improvement group,a depression improvement group,and a placebo group.The cognitive improvement group took 1388 mg of docosahexaenoic acid(DHA)and 692 mg of eicosapentaenoic acid(EPA)every day and the depression improvement group took 1248 mg of EPA and 832 mg of DHA every day.The placebo group took the same dose of soybean oil for 12 weeks,during which psychiatric medication was maintained.The 24-item Hamilton depression scale(HAMD-24)was used to evaluate depressive symptoms,and the standardized MATRICS consensus cognitive battery(MCCB)was used to evaluate cognitive function after 6 weeks and 12 weeks,respectively.Results The study recruited a total of 46 patients with depression including 22 in the cognitive improvement group,12 in the depression improvement group,and 12 in the placebo group.After 6 weeks of treatment,the HAMD-24 scores were significantly lower in the depression improvement group(19.00±10.70)and cognitive improvement group(16.58±9.39)than in the placebo group(31.10±10.03)(P<0.01).After 12 weeks of treatment,HAMD-24 scores were significantly lower in the depression improvement group(13.58±8.43)than in the placebo group(28.10±15.04)(P=0.02).No significant interaction effect was found on the cognitive assessment scores in any dimension after 6 weeks and 12 weeks of treatment(P>0.05).The incidence rate of adverse events in the depression improvement group was 16.7%(2/12),and no adverse events were reported in the other two groups.There was no significant difference in the incidence of adverse events among the three groups(P=0.13).Conclusion Treatment with ω-3PUFA for 6 weeks can improve the depressive symptoms of patients with depression.The formula with a higher ratio of EPA exhibits higher effectiveness while the two groups of ω-3PUFA formulas with different ratios do not improve cognitive function.

Objective    To analyze the short-term and long-term efficacy of staged coronary artery bypass grafting (CABG) and carotid artery stenting (CAS) compared with CABG alone in patients with coronary heart disease with preoperative history of stroke and carotid stenosis. Methods    We reviewed the clinical data of 55 patients (48 males, 7 females, aged 67.62±7.06 years) with coronary heart disease and carotid stenosis who had a history of stroke and underwent CABG+CAS or CABG alone in Zhongshan Hospital from 2008 to 2017. There were 13 patients in the staged CABG+CAS group and 42 patients in the CABG alone group. The differences in the incidence of perioperative adverse events and long-term survival between the two groups were studied, and univariate and multivariate analyses were carried out to determine the independent risk factors of long-term adverse events. Results     Perioperative adverse events occurred in 1 (7.69%) patient of the staged CABG+CAS group, and 4 (9.52%) patients of the CABG alone group (P=0.84). During the follow-up period (67.84±37.99 months), the long-term survival rate of patients in the staged CABG+CAS group was significantly higher than that in the CABG alone group (P=0.02). The risk of long-term adverse events in the staged CABG+CAS group was 0.22 times higher than that in the CABG alone group (95%CI 0.05-0.92, P=0.04). Conclusion    Staged CABG+CAS can significantly improve the long-term survival prognosis without increasing the perioperative risk. It is a safe and effective treatment, but prospective randomized studies are still needed to further confirm this finding.

ObjectiveTo explore the prevalence and influencing factors of multimorbidity among the HIV-infected individuals receiving anti-viral therapy (ART) in Dehong Prefecture of Yunnan Province, so as to provide a reference for the long-term follow-up management of HIV-infected patients and the comprehensive prevention and treatment of chronic diseases. MethodsA cross-sectional study was conducted to investigate the multimorbidity burden among the HIV-infected adults receiving ART in Dehong Prefecture from January to July 2021 and a self-designed questionnaire was used to analyze relevant disease indicators. Multivariate logistic regression analysis was used to investigate the influencing factors of multimorbidity among the HIV-infected individuals. ResultsA total of 3 946 HIV-infected individuals receiving ART were enrolled in this study, of which 63.7% aged ≤50 years, with a male to female ratio of 1.1∶1. Among the 3 946 cases, 825 of them had ≥2 comorbidities, with a co-prevalence rate of 20.9% (95%CI:19.6%‒22.2%), and the main comorbidities were dyslipidemia, diabetes, and hypertension. Multivariate logistic regression analysis showed that 40≤ aged <50 years (aOR=1.86, 95%CI: 1.45‒2.40, P<0.001), 50≤ aged ≤85 years (aOR=3.75, 95%CI: 2.93‒4.80, P<0.001), Dai nationality (aOR=1.21, 95%CI: 1.01‒1.47, P=0.043), BMI≥24.0 kg∙m^-2 (aOR=1.79, 95%CI: 1.49‒2.14, P<0.001), 10.0≤ with ART duration for <12.5 years (aOR=1.49, 95%CI: 1.05‒2.12, P=0.024), with ART duration for ≥12.5 years (aOR=1.50, 95%CI: 1.05‒2.15, P=0.026), use of second-line HIV therapy (aOR=1.43, 95%CI: 1.19‒1.70, P<0.001) and other therapy options (aOR=3.16, 95%CI: 2.17‒4.61, P<0.001) were positively correlated with multimorbidity. ConclusionThe prevalence of multimorbidity among the HIV-infected individuals receiving ART in Dehong Prefecture is high, which is associated with the advancing age and prolonged treatment time, particularly with a significant burden of dyslipidemia, diabetes, and hypertension. Comprehensive surveillance and targeted management of comorbidities, along with ART follow-up, need to be strengthened in the future.

Objective: To investigate the regional differences in the incidence of urothelial carcinoma among kidney transplant recipients between northern and southern China，so as to provide reference for early diagnosis of this disease. Methods: A comprehensive search was conducted across multiple databases，including CNKI，Wanfang，CBM，and PubMed，using the keywords “kidney transplantation” and “tumor” to collect clinical data from qualified kidney transplant centers.The latest and most complete literature data published by 17 transplant centers in northern China and 14 in southern China were included.Statistical analyses were performed to compare the incidence of post-transplant urothelial carcinoma and non-urothelial malignancies. Results: A total of 37 475 kidney transplant recipients were included，among whom 837 (2.23%) developed post-transplant malignancies，including urothelial carcinoma (366/837，43.73%)，non-urothelial carcinoma (444/837，53.05%)，and malignancies with unspecified pathology (27/837，3.23%).The incidence of malignancies was significantly higher in northern China than in southern China [(2.82±1.39)% vs. (1.67±0.83)%，P=0.011]，with a particularly pronounced difference in the incidence of urothelial carcinoma [(1.68±1.12)% vs. (0.32±0.32)%，P<0.001].No significant difference was observed in the incidence of non-urothelial carcinoma between the two regions [(1.11±0.56)% vs. (1.35±0.65)%，P=0.279].Additionally，female transplant recipients exhibited a higher incidence of malignancies than males in both regions (southern China：2.38% vs. 1.80%; northern China：8.93% vs. 2.52%). Conclusion: The incidence of urothelial carcinoma following kidney transplantation is significantly higher in northern China than in southern China，underscoring the importance of implementing regular tumor screening for kidney transplant recipients，particularly for female patients in northern China，to facilitate early diagnosis and timely intervention.
