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.

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.

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.

OBJECTIVETo compare the clinical curative effect of thoracolumbar burst fracture treated by the posterior unilateral approach corpectomy fusion screw-rod fixation and anterior corpectomy bone fusion screw plate fixation.

METHODSFrom January 2008 to May 2014,36 cases of thoracolumbar burst fracture underwent operation of decompression, fusion, and internal fixation was retrospective analyzed. Among them, 16 patients were treated through posterior approach as posterior group, including 13 males and 3 females aged from 37 to 62 years old; 9 cases caused by falling injury, 3 cases by traffic accident injury,4 cases by heavy aboved;the injury segment was on T₁₂ in 2 cases, L₁ in 5 cases, L₂ in 7 cases, L₃ in 2 cases; according ASIA grade, 3 cases were grade A, 2 cases were grade B, 2 cases were grade C, 5 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 5 to 15 days. Other 20 patients were treated through anterior-lateral approach as anterior-lateral group, including 15 males and 5 females with age from 27 to 62 years old; 12 cases caused by falling injury, 4 cases by traffic accident injury, 4 cases by heavy aboved; the injury segment was on T₁₂ in 2 cases, L₁, in 7 cases, L₂ in 9 cases, L₃ in 2 cases; for ASIA grade: 4 cases were grade A, 2 cases were grade B, 4 cases were grade C, 6 cases were grade D, 4 cases were grade E; the time between injury and operation ranged from 4 to 12 days. The operation time, bleeding during operation and postoperative drainage volume were observed in two groups,and the changes of nerve function of ASIA grade, clinical efficacy,improved degree of thoracic and lumbar lordosis,and bony fusion were compared between two groups.

RESULTSAll patients were followed up from 12 to 24 months with an average of (15.8 ± 3.3) months. The operation time, bleeding during operation, and postoperative drainage volume had no significant different between two groups (P > 0.05). As compared with preoperative, ASIA grade of two groups at last follow-up had statistically significantly different (P < 0.01), the neural function of two groups after operation was recovered for different extent. The JOA score of two groups was compared between last follow-up and preoperative, the difference had statistically significant (P < 0.01), the two groups showed good clinical effect. The clinical results of ASIA grade, JOA score and RIS had no significant differences between two groups. All patients of two groups were obtained fusion. Thoracic and lumbar lordosis angle improvement degree had no significant difference between two groups ,it bad significant difference had statistical significance compared with preoperative, the two approaches could effectively restore the spinal sequence.

CONCLUSIONFor patients with thoracolumbar burst fracture just treated by anterior decompression and reconstruction of anterior column, according to the degree of operation performer' skill proficiency and the patient' condition to choose, but for patients must performed the spinal canal decompression anterior and posterior, the three column-reconstruction to required anterior-posterior approach, the posterior unilateral approach corpectomy fusion screw-rod fixation obviously shorten operation time, reduce the operation wound, it is worth the clinical promotion.

Anemia is a frequent and serious complication in patients with inflammatory bowel disease (IBD). One third of patients with inflammatory bowel disease suffers from recurrent anemia. Anemia is associated with a decrease in the quality of life and an increased rate of hospitalization. A number of studies have been conducted and the most relevant conclusions obtained are:(1)anemia is quite common in IBD; (2)although in many cases anemia parallels the clinical activity of the disease, many patients in remission have anemia, and iron, vitamin B12 and/or folic acid deficiency;(3)anemia, and also iron deficiency without anemia, have important consequences in the clinical status and quality of life of the patients;(4)oral iron supplement is limited by poor absorption, intolerance, and induction of oxidative stress at the site of bowel inflammation; (5) intravenous iron sucrose has a high efficiency and a significant improvement in the quality of life; (6)erythropoietin is needed in a significant number of cases to achieve normal hemoglobin levels. Combination therapy with erythropoietin leads to a faster and larger hemoglobin increase. Thus, clinicians caring for IBD patients should have a comprehensive knowledge of anemia, and apply recently published guidelines in clinical practice.
