Objective To investigate the correlation of serum total bile acid (TBA) levels with the inflammation grades of liver tissue in chronic liver diseases.Methods Cyclophorase assay was used to detect the serum TBA levels in 172 patients with various chronic liver diseases,and the inflammation grades of liver tissue were determined by liver biopsy.The correlation between serum TBA levels and the inflammation grades of liver tissue was evaluated using SPSS 12.0 software.Results Serum TBA level was positively correlated with the inflammation grade of liver tissue ( r =0.275,P < 0.01 ).The inflammation grade reached G2 when serum TBA was 20 μmol/L.Conclusion Serum TBA level may be useful for evaluating the inflammation grade of liver tissue in chronic liver diseases.

Objective To review pulmonary CT imaging features and their correlations with the changes on clinical indexes in patients infected with severe fever with thrombocytopenia syndrome bunyavirus (novel bunyavirus).Methods Clinical data and pulmonary CT findings of 19 patients infected with the novel bunyavirus in Zhoushan Hospital and Daishan Hospital of Zhejiang Province during May 2011 and August 2012 were collected.Infection of the novel bunyavirus was confirmed by Zhejiang Provincial Center for Disease Control and Prevention (CDC).All patients received high resolution CT scanning at initial period,critical period and recovery period.And the changes on WBC,platelet (PLT) and lymphocytes (mainly CD4 + T lymphocytes) were observed.Repeated measures analysis of variance and least significant difference (LSD) were performed,and correlation between the changes on clinical parameters and pulmonary imaging was studied.Results In pulmonary CT images,13 out of 19 cases presented groundglass shadow,5 cases presented consolidation shadow,3 cases presented retisculation,5 cases presented pleural thickening and adhesion,and 3 cases presented mediastinal lymphadenopathy.Sixteen patients presented the involvement of bilateral lungs and 3 patients unilateral.Pleural effusion was observed in 11 cases.There were significant differences in WBC,PLT and CD4+T count among initial,critical and recovery periods in 15 patients with obvious lung lesions (F =20.21,28.37 and 32.92,P <0.01).And the above indexes dropped to the lowest points during critical period,which were (1.6 ± 0.6) x 109/L,(26.0 ±9.1) x 109/L and (100.0 ± 66.2) x 106/L,respectively.After treatment,pulmonary CT scan showed that the foci were completely absorbed and no sequelae were observed.Conclusion The changes on pulmonary CT imaging are correlated with those of clinical indexes in novel bunyavirus infection,and the prognosis is good if patients receive the appropriate treatment in the early stage.
