BACKGROUND: Ischemic reperfusion syndrome occurs in early donor liver reperfusion after orthotopic liver transplantation. It is the most important cause for liver function failure and patient death. Ischemic reperfusion severity is closely related to blocking of inferior vena cava period. Some studies demonstrate that inferior vena retrograde perfusion can shorten the blocking time during liver transplantation. OBJECTIVE: To observe the effect of retrograde perfusion on the hemodynamics in orthotopic liver transplantation without venovenous bypass during neohepatic reperfusion phase. DESIGN, TIME AND SETTING: Case comparison was performed at Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from December 2006 to June 2007. PARTICIPANTS: Thirty-nine patients underwent orthotopic liver transplantation without venovenous bypass under general anesthesia. METHODS: According to perfusion methods, the patients were divided into two groups: retrograde perfusion through inferior vena cave (n=19), and perfusion through portal vein (n=20). MAIN OUTCOME MEASURES: The systolic blood pressure, diastolic blood pressure, heart rate, central venous pressure and other hemodynamic parameters were measured before operation, and at anhepatic phase and primary neohepatic phase. The rewarming ischemia time of grafted liver was also recorded. RESULTS: The rewarming ischemia time of grafted liver in the retrograde perfusion through inferior vena cave group was significantly less than that in the perfusion through portal vein group (P

Objective To evaluate the impact of acute hyperglycemia on the short-term prognosis in patients with primary intracerebral hemorrhage (ICH) with meta-analysis. Methods The prospective or retrospective cohort studies or case-control studies of the relationship between baseline blood glucose levels and short-term prognosis (at least were followed up to discharge or 1 month) in patients with ICH within 24 hours were searched and reported. A meta-analysis software package (RevMan 4. 2) was used to pool data for the literatures in accordance with the inclusion criteria. The publication bias was analyzed and the sensitivity analysis was used to evaluate the stability of the results. Results The risk of mortality at the end of the follow up in the normoglycemia group was significantly lower than that in the hyperglycemia group (odds ratio 0. 24,95% CI 0. 19-0. 30; P <0. 000 01); the baseline plasma glucose level was significantly lower than that in the survival group (weighted mean difference -2. 30,95% CI -2. 36- -2.23; P< 0.000 01). Conclusions Acute hyperglycemia can significantly increase the risks of short-term mortality in patients with primary ICH. It is necessary to conduct a prospective randomized trial in order to investigate the effect of intensive glucose control on the prognosis of the patients with ICH.

Objective To evaluate the feasibility and safety of early appendectomy in appendicular abscess. Methods Fifty patients with appendicular abscess who received early appendectomy in our hospital from January 2009 to June 2012 were considered as the abscess group,50 cases patients received acute appendicitis surgery were regarded as the control group. The postoperative hospital stay,cost of hospi-talization,operative time,the amount of bleeding in operation and complications were retrospectively analyzed. Results The operative time of abscess group was (68±23) min,and the control group was (49±14) min (P<0. 05). There were significant differences in operating time between two groups. But there was no significant difference in intraoperatve blood soss,length of stay,the average hospitalization charge and surgical complications (P>0. 05). All patients were cured. Conclusion Early treatment of appendiceal abscess is safe and alternate to conventional conservative treatment followed by interval appendectomy. It is not only to avoid the secondary hospitalization and treatment fail-ure,but also save the cost of hospitalization and minimize the medical expenses.
