Budd-Chiari syndrome is an uncommon but often fatal disorder resulting from obstruction of hepatic venous outflow tract at the level of the hepatic veins,the inferior vena cava. The CT and MRI charac-teristics of Budd-Chiari syndrome are reviewed in this article especially for displaying the exact site and extent of the obstruction. In addition to this direct sign,the indirect findings of venous obstruction such as the presence of intra-and extrahepatic collateral veins,caudate lobe enlargement,inhomogeneous liver enhancement,and regenerative nodules can also be demonstrated. Awareness of these findings is important for early diagnosis and appropriate treatment.

Objective: To investigate prognostic factors of survival of lung adenocarcinoma patients with brain metasta-ses.Methods: The clinical data of 109 lung adenocarcinoma patients with brain metastases were reviewed.Fifty-senven pa-tients survived more than 1 year, and 52 patients survived less than 1 year.The data were analyzed by SPSS 15.0 statisti-cal software.Results: Both the univariate analysis and multivariate analysis showed that patients' PS score, the interval be-tween diagnosis and brain metastasis, and multimodality treatment were independent prognostic factors for the survival of lung adenocarcinoma patients with brain metastases (P<0.05).Patients' gender, age, metastatic symptoms and extracrani-al metastases didn't significantly affect patient survival.Conclusion: Patients with PS score 0-1, the interval of more than 1 year between diagnosis and brain metastasis, and combined therapy have longer survival.The research provides an impor-tant guidance for the treatment of advanced lung adenocarcinoma patients with brain metastases.

Small cell lung cancer (SCLC), which accounts for about 15%of lung cancer cases, is an aggressive disease characterized by rapid growth and early widespread metastasis. Despite sensitive to chemotherapy and radiotherapy, SCLC is vulnerable to get resistant and has high recurrence rates. Therefore, novel therapies are desperately needed to improve treatment efficacy and increase overall survival. A complex molecular biological alteration of SCLC accounts for its pathogenesis and chemo-resistance. With the understand-ing of SCLC biologic behavior and improvement of detection technique, immunotherapy may be a viable therapeutic approach and bring breakthrough to the treatment of patients with SCLC. In this review, we will discuss the rationale for immunotherapy and recent clinical trials of immunotherapeutic agents for SCLC.

K-ras gene is one of oncogenes in non-small cell lung cancer,and it can promote tumor cells growth after mutations by several signaling pathways.K-ras mutations frequently occur in lung adenocarcinoma patients with smoking history.In the present study,K-ras mutations are associated with resistence to targated therapy and may be a marker of poor prognosis in patients with non-small cell lung cancer.

Objective To study whether ANCA liter is sensitive serological marker reflecting vasculitis disease activity. Methods MPO-ANCA and IF-ANCA tilers variation in five sera specimen with active MPA diseases were studied after methylprednisolone and cyclophosphamide pulse therapy. The clinical and pathological features of 5 patients with MPA were investigeted comparing pre-treatment with post-treatment. Results (1) Serum ANCA were found positive and increased liter in 5 patients wilh active MPA disease. (2) Titer decreased after Ireatment, while renal function improved. (3) After half year, MPO-ANCA was negative in 5 patients, IF-ANCA was negative in 2 patients. Conclusion There is a close correlation between serum ANCA titer and MPA renal disease activity.

Laparoscopic hepatectomy has been utilized in clinic,however to some extent there are some limitations for various equipments being used in laparoscopic hepatectomy, as a result, the laparoscopic bepa-tectomy is being constrainted on its development. Therefore, with the research and development of the ideal tool for laparoscopic hepatectomy,laparoscopic liver surgery is bound to be booming.

Cisplatin,carpolatin and oxaliplatin are platinum-based drugs that are widely used in cancer chemotherapy. Peripheral neuropathy is major dose-limiting side effect of platinum-based drug. Accordingly, this side effect restrict its clinic application. This review will focus on the research advancement on the mechanism of dorsal root ganglia neurons apoptosis in cellular and molecular biology.

OBJECTIVE: We aimed to analyze the quality of life (QOL) in adults with allergic rhinitis according to the sensitization profile for relevant aeroallergens in Northern China, investigate the proportion of patients with coexisting asthma, and explore the correlation between QOL of rhinitis patients and the specific IgE level to the causative allergen. METHOD: One hundred and sixty-four allergic rhinitis patients participated in this study, whose clinical history, results of intradermal skin test and serum specific IgE levels to common aeroallergens in North China were collected. QOL was evaluated using the rhinoconjunctivitis quality of life questionnaire (RQLQ). RESULT: QOL of rhinitis patients was worse in those sensitized to tree pollens or weed pollens than those sensitized to house dust mites in Northern China. The proportion of patients with co-existing asthma was lower in tree pollen group than in house dust mite group or weed pollen group, and there was no significant difference between house dust mite group and weed pollen group. There was no significant correlation between QOL of rhinitis patients and the specific IgE level to the causative allergen. CONCLUSION In our study group, QOL of patients with allergic rhinitis varied with the allergen responsible for symptoms, but was not influenced by the specific IgE level to relevant allergen. The proportion of patients with co-existing asthma also varied with different pollen allergens. Rhinitis patients sensitized to weed pollens might be more likely to suffer from asthma than those sensitized to tree pollens.

The effects of two lipids lowering drugs, Xu Zhiping and Mixtura Dai Huai, on the LDL metabolism by receptor dependent and independent pathways in experimental hypercholesterolemia rats were obsvered using radioisotopic double-labelling trace technique. The results showed that in the receptor dependent or independent pathways, the FCR of LDL was increased by 43% and 34% respectively in Xu Zhiping group, and by 35% and 40% respectively in Mixtura Dai Huai group as compared with controls. Both drugs appeared to be more effective than colifibrate, in promoting clearance of LDL from plasma suggesting that the role in reducing plasma TC and LDL-C was depended on accelerating LDL degradation through both receptor dependent and independent pathways. It was also suggested that immune stimulus in combination with cholagogus may become a new way for prevention of hypercholesterolemia and atherosclerosis.

The effects of Da Huai Mixture on receptor dependent and independent pathways of LDL catabolism of the experimental hypercholesterolemic rats were observed by isotope trace-labelling, measurement of monocytic macrophage function and dot bloting. The results were as follows: (1) Serum total cholesterol was significantly decrcased(P
