However, increasing evidence indicates that liver resection is feasible for HCC patients with SPH. Methods: HCC patients with cirrhosis who underwent laparoscopic liver resection(LLR) in two centers from January 2013 to April 2018 were included. Surgical and survival outcomes were analyzed to explore potential prognostic factors. Propensity score matching(PSM) analysis was performed to minimize bias. Results: A total of 165 patients were divided into two groups based on the presence(SPH, n = 76) or absence(non-SPH, n = 89) of SPH. Patients in the SPH group had longer operative time, more blood loss, and more advanced TNM stage than patients in the non-SPH group( P < 0.05). However, there were no significant differences in the postoperative 90-day mortality rate( n = 0), overall postoperative complications(47.4% vs. 41.6%, P = 0.455), Clavien-Dindo classification( P = 0.347), conversion to open surgery(9.2% vs. 6.7%, P = 0.557), or length of hospitalization(16 vs. 15 days, P = 0.203) between the SPH and non-SPH groups before PSM. Similar results were obtained after PSM. The 1-, 3-, and 5-year overall survival(OS) and recurrence-free survival rates in the SPH group were not significantly different from those in the non-SPH group both before and after PSM(log-rank P > 0.05). After PSM, alpha-fetoprotein(AFP) ≥ 400 μg/L [hazard ratio(HR) = 4.71, 95% confidence interval(CI): 2.69-8.25], ascites(HR = 2.18, 95% CI: 1.30-3.66), American Society of Anesthesiologists(ASA) classification(Ⅲ vs. Ⅱ)(HR = 2.13, 95% CI: 1.11-4.07) and tumor diameter > 5 cm(HR = 3.91, 95% CI: 2.02-7.56) independently predicted worse OS. Conclusions: LLR for patients with HCC complicated with SPH appears feasible at the price of increasing operative time and blood loss. AFP, ascites, ASA classification and tumor diameter may predict the prognosis of HCC complicated with SPH after LLR.展开更多

Methods Data about 2 568 patients with acute ischemic stroke were collected from 4 hospitals in Shandong Province from January 2006 to December 2008. National Institute of Health Stroke Scale （NIHSS） 〉10 at discharge or death was defined as the outcome. Effect of dyslipidemia on outcome in patients with acute ischemic stroke was analyzed by multivariate logistic regression analysis and propensity score-adjusted analysis, respectively. Results The serum levels of TC, LDL-C, and HDL-C were significantly associated with the outcome in patients with acute ischemic stroke. Multivariate logistic regression analysis and propensity score-adjusted analysis showed that the ORs and 95% CIs were 3.013 （1.259, 7.214）/2.655 （1.298, 5.43）, 3.157 （1.306, 7.631）/3.405 （1.621, 7.154）, and 0.482 （0.245, 0.946）/0.51 （0.282, O.921）, respectively, for patients with acute ischemic stroke. Hosmer-Lemeshow goodness-of-fit test showed no significant difference in observed and predicted risk in patients with acute ischemic stroke （chi-square=8.235, P=0.411）. Conclusion Serum levels of TC, LDL-C, and HDL-C are positively related with the outcome in patients with acute ischemic stroke.展开更多

文摘Background:The optimal regimen of infliximab salvage in acute severe ulcerative colitis(ASUC)patients remains controversial.This study aimed to compare accelerated and standard infliximab induction in Chinese ASUC patients,and to explore risk factors and concrete accelerated regimens for them.Methods:Data were retrospectively collected from steroid-refractory ASUC patients receiving infliximab as rescue therapy at seven tertiary centers across China.Outcomes including colectomy and clinical remission(Mayo score≤2 and every subscore≤1 at Day 14)rates were compared between patients receiving accelerated and standard infliximab induction using propensity score adjust-ment for potential confounders.The dose-response relationship was explored by plotting restricted cubic splines.Logistic regression and Cox proportional hazards regression analyses were performed to determine risk factors for adverse outcomes.A systematic re-view and meta-analysis was also performed.Results:A total of 76 patients were analysed:29 received standard and 47 received accelerated induction.The accelerated group had a higher 90-day colectomy rate(17.8%vs 0%,P=0.019)and lower clinical remission rate(27.7%vs 65.5%,P=0.001).After adjust-ing for propensity score and institution,there was no significant difference in colectomy or clinical remission rates(both P>0.05).Dose-effect curves showed decreased colectomy hazard with higher cumulative infliximab dosage within 5 days,with no improve-ment observed for increasing cumulative infliximab dosage within 28 days.Multivariate logistic regression analyses revealed C-reac-tive protein of>10 mg/L at infliximab initiation(odds ratio?5.00,95%confidence interval:1.27-24.34)as an independent risk factor for no clinical remission.Meta-analysis also revealed no significant difference in colectomy rates at 3 months(P=0.54).Conclusions:After adjusting for confounders,there were no significant differences in colectomy or clinical remission rates between accelerated and standard infliximab induction among ASUC patients.Early administration of an intensified dosage within 5 days may be beneficial.Elevated C-reactive protein at infliximab initiation indicated need for intensive treatment.

Results The serum levels of TC, LDL-C, and HDL-C were significantly associated with the outcome in patients with acute ischemic stroke. Multivariate logistic regression analysis and propensity score-adjusted analysis showed that the ORs and 95% CIs were 3.013 （1.259, 7.214）/2.655 （1.298, 5.43）, 3.157 （1.306, 7.631）/3.405 （1.621, 7.154）, and 0.482 （0.245, 0.946）/0.51 （0.282, O.921）, respectively, for patients with acute ischemic stroke. Hosmer-Lemeshow goodness-of-fit test showed no significant difference in observed and predicted risk in patients with acute ischemic stroke （chi-square=8.235, P=0.411）. Conclusion Serum levels of TC, LDL-C, and HDL-C are positively related with the outcome in patients with acute ischemic stroke.
文摘Aim:To elucidate the role and efficacy of laparoscopic liver resection for elderly patients with hepatocellular carcinoma(HCC).Methods:A retrospective comparative analysis was performed between laparoscopic and open liver resection operated from year 2008 to 2018.Consecutive HCC patients aged 65 or above at the time of operation were recruited.Patients with recurrent HCC and/or alternative pathology were excluded.Short-term and long-term outcomes between the laparoscopic and the open group were compared.Propensity score matching of patients in a ratio of 1:2 was conducted before comparison.Results:A total of 911 patients underwent hepatectomy for primary HCC from 2008 to 2018.Among them,320 elderly patients aged over 65 years old were eligible for analysis.Heterogeneities between laparoscopic and open groups were identified namely pre-operative albumin level,aspartate transaminase,and magnitude of hepatectomy(major vs.minor).After propensity score matching of 1:2,46 patients in the laparoscopic group and 92 patients in the open group were included for comparison.The laparoscopic group had less blood loss(326 mL vs.735 mL;P<0.001),shorter operative time(223 min vs.324 min;P<0.001),and shorter hospital stay(6.3 days vs.10.5 days;P<0.001).No significant differences in postoperative morbidity and hospital mortality were noted between the groups.For oncological outcome,the laparoscopic group had a superior disease-free survival(59.7%vs.44.5%;P=0.041),and a trend towards better overall survival compared with the open group.(78.4%vs.64.8%;P=0.110).Conclusion:Laparoscopic liver resection is a safe approach for elderly patients with HCC with benefits from faster recovery and better oncological outcomes.
