Objective To study the normal angiographic anatomy and variations of rabbit hepatic vessels,and explore the optimal method for hepatic artery catheterization.Methods 30 rabbits were divided into two groups randomly.Modified surgical method and interventional method were used to catheterize hepatic artery respectively,and followed by angiography to demonstrate the normal anatomy and variations of rabbit celiac artery,hepatic artery and portal vein.Results The route and distribution of rabbit celiac artery and hepatic artery were very different from human's.The commonly seen variation showed the differences in branching bifurcation of hepatic-gastric artery,with the incidence of 13.3%.The rates of successfully hepatic artery catheterization with surgical and interventional methods were 86.6%(13/15)and 80%(12/15)respectively (P＞0.05).The surgical method will not be successful,whenever there's variation.Conclusion The normal anatomy and variation of rabbit celiac artery and hepatic artery are quite different from human's.Both surgical and interventional catheterizations could be rather successful but possessing advantages and disadvantages of each its own.

OBJECTIVETo evaluate the efficacy and safety of five-year trail of entecavir for chronic hepatitis B patients failed with lamivudine therapy in the Chongqing area.

METHODS32 patients failed with lamivudine therapy were enrolled in this study. In the double-blind phase, patients were randomly divided into entecavir 1.0 mg/d group (n = 28) and placebo group(n = 4) for 12 weeks. In the open-lable phase, patients received ETV 1.0 mg/d for 240 weeks. HBV DNA level, liver function, HBV serology were observed.

RESULTSThe mean reduction in HBV DNA level at week 12 was 4.05 log10 copies/ml in ETV group, and 0.08 log10 copies/ml in placebo group (P less than 0.05). The mean of HBV DNA level after 240 weeks of ETV treatment was decreased to 2.58 log10 copies/ml. The proportion of patients with HBV DNA less than 3 log10 copies/ml was 0, 6.25%, 15.6% , 50%, and 57.14% at 0, 8, 24, 96 and 240 weeks respectivfely. There were 2 patients with HBsAg seroconversion and 4 patients with HBeAg seroconversion at the end of the study. The ALT level returned to normal at week 12 and remained normal throughout the following 240 weeks. One patient had a severe adverse event during the trail.

CONCLUSIONEntecavir is effective and safe for the chronic hepatitis B patients failed with lamivudine therapy.

Objective This study was to investigate the role of lactoferrin and C-reactive protein (CRP)assay in ascitic fluid for diagnosis of spontaneous bacterial peritonitis (SBP)in the patients with decompensated liver cirrhosis.Methods Ascites was collected from the inpatients with decompensated liver cirrhosis before and after treatment from May to December 2011 for anal-ysis of polymorphonuclear cells (PMN)and bacterial culture.The level of lactoferrin and C-reactive protein in the ascites were determined.Results A total of 117 ascites samples were collected from 66 patients.Twenty-six patients met the criteria of SBP with PMN ≥ 250×106/L in ascites,were assigned to SBP group.Of these patients,11 presented with fever 37.3℃ to 38℃, and 11 patients had elevated peripheral blood white cell count > 10 × 109/L.Eleven patients had neutrophil cell percentage >0.75.Only 8 patients in this group had positive bacterial culture.Another 12 patients met the criteria of suspected SBP,and assigned to suspected SBP group.The remaining 28 patients did not satisfy the criteria of SBP,and assigned to non-SBP group.The pretreatment lactoferrin level was (768.46 ± 611 .70)ng/mL and (98.28 ± 56.81 )ng/mL in SBP and non-SBP group,respectively.The pretreatment CRP level was (9.397 ±3.737 )mg/L and (1 .786 ±0.52 )mg/L in SBP and non-SBP group,respectively.The lactoferrin and CRP levels decreased sharply after antibacterial and support-ive treatment in SBP group,which were 657.05 ng/mL and 8.13 mg/L,respectively.The cut-off value of lactoferrin for diagnosis of SBP was 233 ng/mL with sensitivity 96.2% and spe-cificity 97.5%.The cut-off value of CRP for diagnosis of SBP was 4.390 mg/L with sensitivity 92.3% and specificity 92.5%. However,lactoferrin combined with CRP had a sensitivity of 99.70% and specificity of 90.18% for diagnosis of SBP.Conclu-sions Lactoferrin and CRP levels in the ascites of patients with liver cirrhosis are useful for diagnosis of SBP with high specifici-ty and sensitivity.

Medical science has both the characteristics of natural science and humanities.Modem medical education pays more attention to the close association between professional education and humanistic education.How to handle the relationship between infectious disease and humanistic education has become more and more important.In current study,integrating humanistic education in clinical infectious disease teaching not only improved infectious disease teaching effect but also established good medical ethics and increased the comprehensively quality.

Medical ethics is correlated with further development of affiliated teaching hospital.Our hospital took ‘ Bethune spirit’ and philosophy of forgiveness and kindheartedness as guidance and became the first batch of Bethune spirit model hospital of Chongqing.Teaching quality was improved by providing lectures about ‘ Bethune spirit’ for medical students and equally emphasizing medical knowledge and medical ethics education.Anti-corruption and academy governing movements with the subject of ‘ Bethune spirit’ were carried out to repel academic misdeed,with the result that clinical,teaching and scientific works were promoted and advanced.

To clarify the prognostic contribution of peripheral blood cell and bone marrow megakaryocyte counts in patients with idiopathic thrombocytopenic purpura, a series of data of 299 ITP patients including the counts of peripheral white blood cells and platelets, their increase potentials after treatment and the megakaryocytic counts on the bone marrow smears at diagnosis as well were collected and retrospectively analyzed to correlate with the disease development. The results showed that peripheral white blood cell and platelet counts at diagnosis were not associated with the prognosis, but positively associated with the increment of platelet counts after treatment. The cure rate reached up to 94.9% in the group with the platelet level restored to 100 x 10(9)/L in two weeks of therapy. The numerous megakaryocyte counts in bone marrow at diagnosis indicated good prognosis that the cure rate was up to 86.1% when the counts were more than 100 per 1.5 x 3 cm of smear. In conclusion, bone marrow examination on the quantity and quality of megakaryocyte would be critical for diagnosis and evaluation of the prognosis. Consecutive platelet counts during therapy is useful to estimate the disease development.
