ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

OBJECTIVE:To systematically review the effect of ticagrelor versus prasugrel on platelet reactivity,and provide evi-dence-based reference for clinical treatment. METHODS:Retrieved from PubMed,CJFD and Wanfang Database,randomized con-trolled trials(RCT)about the effect of ticagrelor versus prasugrel on platelet reactivity were collected. Meta-analysis was performed by using Rev Man software after data extract and quality evaluation by Cochrane 5.1.0. RESULTS:Totally 17 RCTs were enrolled,involv-ing 2 757 patients. Results of Meta-analysis showed,regardless of Verity Now(VN)detection method [MD=15.43,95%CI(-0.39, 31.25),P=0.06] or vasodilator stimulus phosphoprotein(VASP)detection method [MD=-3.04,95%CI(-8.98,2.90),P=0.32], ticagrelor and prasugrel had the same effects on platelet reactivity under loading dose,the differences were not statistically significant;regardless of VN detection method [MD=-48.94,95%CI(-58.04,-39.84),P<0.001] or VASP detection method [MD=-14.32, 95%CI(-20.45,-8.20),P<0.001],the effects of ticagrelor were better than prasugrel on platelet reactivity under maintenance dose,the differences were statistically significant. CONCLUSIONS:At the loading dose,there was no difference between ticagrelor and prasugrel,but ticagrelor has more benefits than prasugrel under maintenance dose.

Objective To evaluate left ventricular rotation and torsion and its early recovery after percutaneous coronary intervention (PCI) in patients with coronary heart disease and normal left ventricular ejection fraction (LVEF) using two dimensional speckle tracking echocardiography.Methods Twenty three consecutive patients with coronary heart disease and normal LVEF were divided into group B (with coronary stenosis ＜70％) and group C (with coronary stenosis ＞70％ and with PCI).Along with 11 healthy controls(group A),indices including basal rotation (BR),apical rotation (AR),left ventricular torsion (LVT) and normalized time to peak were compared among groups,correlative analysis was made between LVT and each indices mentioned above,indices of group C before and 24 hours after PCI were compared.Results AR,LVT in group B and C reduced relative to group A (P ＜0.05),meanwhile time to peak of BR in group C shortened relative to other groups.BR,AR and normalized time to peak of BR were correlated to LVT respectively.BR and LVT in group C increased after PCI(P ＜0.05).Conclusions AR was sensitive to ischemia,the reduction of time to peak of BR in group C might be restriction and compensation.Sensitive to early recovery of left ventricular function after reperfusion,BR could be a predictive index of early effect of percutaneous coronary intervention.
