BackgroundPatients with chronic schizophrenia often suffer from cognitive impairment. Traditional cognitive rehabilitation training has problems such as a single form and poor compliance， making it urgent to develop new cognitive intervention methods. ObjectiveTo explore the intervention effect of smartphone games on the cognitive function of patients with chronic schizophrenia， and to analyze the differences in cognitive function improvement between patients of different genders， in order to provide references for the cognitive function intervention of these patients. MethodsThis study was a prospective cohort study. A total of 30 patients who were hospitalized in the Psychiatry Department of Chaohu Hospital Affiliated to Anhui Medical University from March to October 2021， met the diagnostic criteria for schizophrenia as defined in the International Classification of Diseases， tenth edition （ICD-10）， and had a disease duration of above 5 years， were selected as the research subjects. All patients received smartphone game intervention for 12 weeks， 5 times a week， each session lasting 1 hour， in addition to conventional antipsychotic drug treatment. At the baseline and at 3， 6， 9， and 12 weeks of the intervention， the cognitive function was evaluated using the Repeatable Battery for the Assessment of Neuropsychological Status （RBANS）， the Positive and Negative Syndrome Scale （PANSS） was used to assess mental symptoms， and the Problematic Mobile Gaming Questionnaire （PMGQ） was used to assess addiction symptoms. ResultsA total of 26 patients （86.67%） completed the study， including 13 females and 13 males. The time effects， group effects， and interaction effect between time and group for the immediate memory factor score of RBANS in the female group and the male group were all statistically significant （F=36.682， 5.712， 3.090， P<0.05 or 0.01）， and the time effects and group effects for the verbal and delayed memory factors as well as the total score in both groups were also statistically significant （F=3.841， 6.149， 15.372， P<0.05 or 0.01）. The time effects and group effects of the total score of PANSS in both groups had no statistical significance （F=2.041， 0.623， P>0.05 for both）， and the interaction effect between time and group was statistically significant （F=5.728， P<0.01）. The time effects， group effects， and interaction effect of the total score of PMGQ in both groups were all without statistical significance （F=2.672， 0.166， 0.642， P>0.05 for both）. ConclusionSmartphone game intervention may help improve the cognitive function of patients with chronic schizophrenia （especially immediate memory， verbal function， and delayed memory）， and the benefits are greater for female patients. The smartphone game intervention did not induce game addiction， but no significant improvement in psychotic symptoms was observed. ［Funded by Excellent Young Talents Support Program of Anhui Provincial Department of Education （number， gxyqZD2022022）； www.chictr.org.cn number， ChiCTR2100044113］

Objective:To evaluate the outcomes of intensive conservative treatment compared to conventional conservative treatment in patients with acute aortic syndrome(AAS).Methods:The study prospectively enrolled consecutive patients with AAS who were admitted to Beijing Anzhen Hospital, affiliated with Capital Medical University, and Beijing Dawanglu Emergency Rescue Hospital from January 2024 to December 2024. These patients with surgical contraindications or refused surgery for various reasons opted for conservative treatment. A total of 282 patients were included, and 15 patients with missing data or those who died without any treatment were excluded. Finally, 267 patients were enrolled, of whom 94 received intensive conservative treatment, and 173 received conventional conservative treatment, the inverse probability of treatment weighting (IPTW) was used to reduce the influence of confoundings. After adjusting of baseline datas via IPTW, the survival outcomes of the two groups were compared at 14 days, 30 days, and at the end of follow-up.Results:The results showed significant differences in acute phase survival rates between the enhanced conservative treatment group and the conventional conservative treatment group at 14 days(82.40%vs.53.20%, P<0.0001). Significant survival differences were also observed at 30 days and at 276-day mid-term follow-up (96.29% vs.51.60%, P<0.0001; 78.50% vs.48.50%, P<0.0001). In the subgroup analysis, for type A aortic dissection, the enhanced conservative treatment group had higher survival rates compared to the conventional conservative treatment group at 14, 30 and 276 days (63.46% vs.41.35%, P<0.05; 52.17% vs.37.90%, P<0.05; 50.00% vs. 31.97%, P<0.05). However, for type B aortic dissection, although the enhanced conservative treatment group had higher survival rates than the conventional conservative treatment group, no statistically significant differences were observed (96.29% vs. 80.00%, P=0.054; 95.65% vs.78.37%, P=0.067; 94.12% vs.74.20%, P=0.088). Conclusion:For patients diagnosed with AAS are forced to choose conservative treatment if emergency surgery is not possible in the first place, intensive conservative treatment strategies can significantly reduce the mortality in the acute phase compared with conventional conservative treatment. Mid-term follow-up, intensive conservative treatment still has a significant survival advantage.

Objective:To investigate the relationship between the distal fractional flow reserve(FFR-CT) of the left anterior descending artery(LAD) measured by aortic CTA and the intraoperative left internal mammary artery(LIMA-LAD) graft flow during off-pump coronary artery bypass grafting(OPCABG). And to evaluate the role of FFR-CT in predicting intraoperative flow characteristics, competitive flow, and diffuse coronary lesions.Methods:Retrospectively included 162 OPCABG patients who underwent LIMA-LAD grafting. The primary outcome was the average flow value(Qm) of the LIMA-LAD graft measured intraoperatively. Smooth curve fitting and linear regression analysis were used to explore the relationship between preoperative LAD distal FFR-CT values and the intraoperative LIMA-LAD graft flow Qm.Results:Group analysis showed that Qm significantly decreased as the distal FFR-CT values increased. Smooth curve fitting revealed a " reverse U-shaped" relationship between LAD distal FFR-CT and Qm. When the FFR-CT value>0.64, Qm demonstrated a significant negative linear correlation with FFR-CT(regression coefficient β=-178.6432, P=0.004). Conclusion:A distal FFR-CT value of >0.64 in the LAD may increase the risk of competitive flow in the LIMA-LAD graft, while excessively low FFR-CT values likely reflect diffuse coronary lesions, leading to a reduction in graft flow.

BackgroundAgomelatine， a novel antidepressant with dual efficacy in mood improvement and sleep regulation， has been widely utilized in clinical treatment of depressive disorders. The association between agomelatine and hepatic dysfunction has garnered increasing attention， yet there remains limited research on its long-term effect of liver function in real clinical scenarios. ObjectiveTo investigate the effect of different doses of agomelatine on liver function in patients with depressive disorders in real clinical scenarios， and to ascertain its safety profile and efficacy differences. MethodsA retrospective study was conducted， enrolling 200 patients diagnosed with depressive disorders according to the International Classification of Diseases， tenth edition （ICD-10）， who received agomelatine treatment at the Department of Psychiatry of Chaohu Hospital Affiliated to Anhui Medical University from January 2019 to December 2024. Longitudinal follow-up was performed based on real-world data. Patients were divided into a low-dose group （25 mg/d） （n=121） and a high-dose group （50 mg/d） （n=79） based on their agomelatine dosage. Follow-up assessments were conducted at baseline， the 2^nd， 6^th， 14^th， and 26^th weeks after treatment initiation. Liver function indicators， including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and total bilirubin （TBIL）， were measured using a fully automated biochemical analyzer. Clinical symptoms were evaluated using the Hamilton Depression Scale-24 item （HAMD-24） and the Hamilton Anxiety Scale （HAMA）. ResultsNo statistically significant time effect， intergroup effect， or time-by-group interaction effect was observed for ALT， AST， or TBIL in either the low-dose or high-dose group （P>0.05）. The time effects for both HAMD-24 and HAMA scores in the two groups were statistically significant （F_time=430.573， 395.737， P<0.01）. From the end of the 2^nd week of treatment onward， the scores at each follow-up time point were significantly lower than those at the baseline period （P<0.01）. ConclusionBoth low-dose and high-dose agomelatine may have no significant effect on liver function in patients with depressive disorders， with no difference in liver function impairment was observed between dosage groups. Low-dose and high-dose agomelatine may be equally effective in alleviating depressive and anxiety symptoms in patients with depressive disorders. ［Funded by the Education Work Committee of the Anhui Provincial Committee for Outstanding Young Talents in Colleges and Universities （number， gxyqZD2022022）； the Key Project of Scientific Research Fund of Anhui Institute of Translational Medicine （number， 2023zhyx-B18）］

Objective To investigate the correlation between red blood cell distribution width(RDW),systemic immune-inflammation index(SII)and major depressive disorder(MDD).Methods The clinical data of 176 MDD patients hospitalized in the clinical psychology department of our hospital from 2020 to 2022 and 209 non-MDD comparators who were routinely examined in Hebei General Hospital were retrospectively analyzed.Blood analysis was conducted to obtain values of RDW,SII,and red blood cell distribution width/platelet ratio(RPR).The data was used to plot the receiver operator characteristic(ROC)curve to determine the optimal threshold and the area under the curve(AUC)for RDW to discriminate between patients and controls.Result Patients in the MDD group had significantly higher RDW[median and quartiles:13.20(12.70,13.98)vs.12.80(12.40,13.35)],and SII levels[median and quartiles 510.87(350.95,878.12)vs.405.33(313.74,539.92)]compared with those in non-MDD group(P<0.05).There was no significant difference in RPR between the two groups(P>0.05).Multifactorial logistic regression analysis showed that RDW was positively correlated with MDD after adjusting for confounders(OR=3.086,95% CI:1.926-4.944).ROC curve showed that the optimal threshold for RDW to differentiate the risk of developing MDD was 12.85,with an AUC of 0.647(95% CI:0.592-0.702;P<0.001).Conclusion Present study shows that high RDW is a risk factor for the occurrence of MDD and an important parameter for the risk of developing depression.

Objective:To explore the risk factors of ischemic stroke after coronary artery bypass grafting(CABG) in elderly(≥75 years old)patients, establish a risk prediction model and evaluate it.Methods:From January 2015 to September 2021, a total of 1 553 elderly patients with coronary artery disease who were admitted to Beijing Anzhen Hospital for coronary artery bypass grafting were included retrospectively. Among which 1 121(72%) cases were males, with a median age of 77( IQR 75, 78) years. Clinical data were collected and univariate analysis and multiple logistic regression analysis were used to explore the risk factors of ischemic stroke after CABG in elderly patients. After the establishment of risk prediction model, we constructed the nomogram, and tested the discrimination and calibration of the model. Results:All patients underwent CABG, there were 35 patients with ischemic stroke after operation, with an incidence of 2.25%(35/1 553). Multivariate logistic regression analysis showed that diabetes( OR=2.61, 95% CI: 1.31-5.32), old myocardial infarction( OR=3.62, 95% CI: 1.61-7.63), systolic blood pressure( OR=1.03, 95% CI: 1.01-1.04) and vertebral artery stenosis( OR=1.01, 95% CI: 1.00-1.02) were independent risk factors for postoperative cerebral infarction in patients undergoing CABG. The model was presented by a nomogram, and the model discrimination was evaluated by ROC curve. The area under the curve( AUC) was 0.757, indicating a optimal discrimination. Hosmer- Lemeshow test of goodness of fit was performed to evaluate the model calibration( χ2=6.209, P=0.624). Conclusion:Diabetes mellitus, old myocardial infarction, systolic blood pressure and vertebral artery stenosis are independent risk factors for ischemic stroke in elderly patients after CABG. The established risk prediction model has optimal discrimination and calibration.

Objective:To evaluate the perioperative and follow-up data of carotid artery stenting (CAS)+ coronary artery bypass grafting (CABG) and CABG alone, and to assess the safety and efficacy of CAS in the treatment of severe stenosis of the carotid artery in combination with asymptomatic carotid artery stenosis.Methods:A retrospective analysis of 700 CABG patients combined asymptomatic carotid artery severe stenosis at Beijing Anzhen Hospital, Beijing Chaoyang Hospital, and Beijing Tiantan Hospital from January 2018 to December 2022 was performed. According to whether or not underwent CAS treatment, they were divided into the CAS-CABG group(116 cases)and the CABG-only group(584 cases). The mean age of the CAS-CABG group was (64.8±7.3) years, and all of them underwent unilateral CAS surgery only; the mean age of the CABG only group was (65.5±7.6) years. The main results of the patients in the two groups were compared at 30 days after the operation and follow-up period.Results:The early postoperative stroke rate was significantly lower in the CAS-CABG group(2.6% vs. 9.1%, P=0.02), while the combined procedure did not increase the rates of mortality and adverse events during follow-up. Subgroup analysis revealed that there was no significant difference in stroke rates between the two procedures for asymptomatic unilateral carotid artery stenosis, advanced age, history of atrial fibrillation, and history of stroke were independent risk factors for early stroke in CABG for asymptomatic unilateral carotid artery stenosis. Conclusion:CAS-CABG is safe and effective in the treatment of coronary artery disease combined with asymptomatic carotid artery stenosis, and can reduce the incidence of early postoperative stroke in patients. CABG patients with asymptomatic carotid stenosis should be rationally screened for prophylactic CAS to reduce the risk of postoperative stroke in these patients.
