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 investigate the relationship betweenthe stability of carotid artery plaque and cystatin C,homocysteine. Methods A total of 1 50 cerebral infarction patients with carotid artery plaque treated in Hospital of the First Electricity Authority in Guangdong were selected as the research subjects.According to Color Doppler ultrasound scanning,the patients were divided into the observation group (86 unstable plaque patients)and control group(64 stable plaque patients).Peripheral venous blood from the patients of both groups were collected for the detection of cystatin C,homocysteine,serum total cholesterol and fibrinogen levels and the results of detection were compared between the two groups.Results The levels of cystatin C,homocysteine,serum total choles-terol and fibrinogen in the observation group were significant higher than those of the control group(t =48.760,20.530,29.860, 33.720,P <0.05).The level of cystatin C was weak positive correlated with homocysteine(r =0.21,P <0.003).Multivariate lo-gistic regression analysis showed cystatin C,homocysteine,serum total cholesterol and fibrinogen were independent risk factors for carotid artery plaque instability in patients with cerebral infarction.Conclusion Cystatin C,homocysteine,serum total cholesterol and fibrinogen are important risk factors for carotid plaque instability,the cerebral infarction is closely related to the carotid artery plaque stability,so controlling the risk factors is the focus of prevention and treatment of cerebral infarction.

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.

Objective To identify the correlation between doctors' job burnout and medical errors.Methods In stage 1,a cross-sectional retrospective survey on doctors' job burnout and medical errors was conducted for 300 doctors serving in the First Affiliated Hospital of Fujian Medical University,who were randomly sampled in June 2013.The survey covered basic demographic information,self-assessed job burnout and medical errors.In stage 2,231 doctors without medical errors in stage 1 were selected for a prospective study focusing on a follow-up on their medical errors within half a year.Results Medical errors were found to influence job burnout of doctors significantly.Multiple logistic regression analysis was made based on the three independent variables of A-emotional exhaustion,B-depersonalization,and C personal sense of accomplishment,and the dependent variables Y1 and Y2 indicating the occurrence or non-occurrence of common medical errors or serious medical errors,respectively.The calculation aims to identify if there is line relationship among the three independent variables.Conclusions This study suggests that all kinds of medical errors influence job burnout;scores of the three dimensions of job burnout may be predictors of occurrence of different medical errors.

Objective To analyze and compare the incidence of cerebral vasospasm (CVS) in patients with aneurismal subarachnoid hemorrhage(aSAH) in China and in Europe.Methods A literature search was performed for all the papers investigating the incidence,diagnosis, treatment or prognosis of CVS after aSAH using the MEDLINE and China Knowledge Resource Integrated Database (CNKI) from January 1, 1990 to December 31, 2010.The incidences of angiographic CVS, symptomatic CVS and CVS-related infarcts were recorded.The incidences of CVS between Chinese and white men in Europe were compared. Results A total of 237 articles were searched via CNKI and reference reviews, and 9 of the studies met the inclusion criteria. A total of 172 articles were searched via MEDLINE and reference reviews, and 18 of the studies met the inclusion criteria. The risk of occurring symptomatic CVS in patients with aSAH in Chinese was significantly higher than that in white men in Europe (relative risk,2. 063, 95％ confidence interval 1.816-2. 343, P ＜0. 001). Conclusions The incidence of CVS in patients with aSAH in Chinese was significantly higher than that in white men in Europe,indicating the pathogenesis of CVS may have genetic basis.

Objective To investigate the relationship between the serum uric acid (SUA) levels and the short-term clinical outcome in patients with spontaneous intracerebral hemorrhage.Methods Consecutive patients with spontaneous intracerebral hemorrhage admitted within 24 hours after onset were prospectively included.SUA levels was measured on the next morning after admission.Modified Rankin Scale (mRS) was used to ascertain clinical outcome at 30 days.The patients were divided into a good outcome group (mRS＜2) and poor outcome group (mRS≥3).Results A total of 92 patients with spontaneous intracerebral hemorrhage were included,and 46 of them (50％) were men,the mean age was 63 ± 12 years.At 30 days after onset,22 patients (23.9％) had a good outcome and 70 patients (76.1％) had a poor outcome.Univariate analysis showed that the Glasgow Come Scale (GCS) score in the good outcome group was significantly higher than that in the poor outcome group (13.85 ± 2.80 vs.11.21 ± 2.51; t=4.186,P=0.000),while hematoma volume (25.65 ±5.33 cm3 vs.34.60± 8.97 cm3,t=4.430,P=0.000) and SUA levels (324.90± 86.02 μmol/L vs.458.63 ±72.77 μmol/L; t =7.193,P =0.000) were significantly lower than those in the poor outcome group.Multivariate logistic regression analysis showed that the lower GCS score (odds ratio [OR]1.810,95％ confidence interval [CI]1.382-2.382; P =0.001),larger hematoma volume (OR 1.156,95％ CI 1.045-1.280; P=0.005) and higher SUA levels (OR 2.127,95％ CI 1.055-4.287; P=0.035) were the independent predictive factors for the short-term clinical outcome in patients with spontaneous intracerebral hemorrhage.Conclusions The increased SUA levels may predict the poor short-term clinical outcome in patients with spontaneous intracerebral hemorrhage.
