RESUMEN
Objective To investigate the changes and clinical correlation of IL-4 in patients with HBV infection.Methods Sixty cases with chronic asymptomatic HBV carriers,60 cases with chronic hepatitis B,60 cases with liver cirrhosis,60 cases with hepato-cellular carcinoma and 50 healthy controls were collected for serum.ELISA was used for detection of cytokine IL-4 levels;The a-mount of HBV DNA was measured by fluorescence quantitative PCR;Liver function was tested by automatic biochemical analyzer. Results Compared with the healthy controls[(1.64±0.17)ng/mL],IL-4 levels of patients with CHB,LC and HCC were signifi-cantly increased[(4.18±0.48),(4.71±0.42),(3.62±0.31)ng/mL,P <0.05].LC group have the highest IL-4 levels,while ASC was the lowest.Compared with the ASC group,IL-4 levels of patients with CHB,LC and HCC were significantly increased(P <0.05).Compared with the HCC group,IL-4 levels of patients with LC were significantly increased(P <0.05).IL-4 level was posi-tively correlated with TBIL levels in LC patients(r=0.529,P <0.01),while the IL-4 level was positively correlated with ALT and TBIL level in HCC patients(r=0.263,0.323,P <0.05).Conclusion IL-4 may play an important role in chronic HBV infection, the levels of IL-4 can be used as an important indicator to assess the severity of chronic hepatitis B.
RESUMEN
Objective To explore changes of levels of interferon‐γ(IFN‐γ) ,interleukin‐32(IL‐32) and interleukin‐6(IL‐6) in pe‐ripheral blood and the correlation between peripheral IFN‐γ,IL‐32 ,IL‐6 and liver function level and hepatitis B virus(HBV) DNA load in HBV carriers .Methods Sixty HBV carriers ,including 39 cases of chronic HBV carriers and 21 cases of inactive hepatitis B surface antigen(HBsAg) carriers ,and 50 healthy individuals were collected .Serum levels of IFN‐γ,IL‐32 and IL‐6 ,the amount of HBV DNA and liver function were detected ,and clinical correlations were analysed .Results Compared with the control group ,ser‐um levels of IFN‐γ,IL‐32 and IL‐6 of chronic HBV carriers and inactive HBsAg carriers were significantly increased (P0 .05) .There was positive correlation between IL‐32 level and ALT level (r=0 .32 ,P<0 .05) ,and negative correla‐tion between IL‐32 level and ALB level(r= -0 .27 ,P<0 .05) .Conclusion IFN‐γ,IL‐32 and IL‐6 may play important roles in chro‐nic HBV infection ,the levels of IFN‐γ,IL‐32 and IL‐6 could be used as important indicators to assess the severity of inflammation in HBV carriers .
RESUMEN
Objective To evaluate the risk factors of myasthenic crisis(MC) after thymectomy for myasthenia gravis (MG) Methods A retrospective study was conducted in 84 patients with MG from July 1995 to December 2009. The following factors were evaluated: sex, age, history of preoperative myasthenic crisis, Osssrmen classification, use steroid hormones and anticholinesterase drugs before operation, operation methods, operation time, thymoma, pathology, transfusion, course of disease, postopertive lung infection,etc. Multivariate logistic regrossion analysis was used to find the predictors of postoperative myasthenic crisis. Results Twenty-four patients(28.6%) developed myasthenic crisis after thymectomy. Statistics showed that history of preoperative myasthenic crisis, Ossermen classification, operation methods, operation time were related to postoperative myasthenic crisis. Conclusion Preoperative myastheric crisis, Ossermen classification≥I b, traditional operation methods, long opertion time are the independent risk factors for myasthenic crisis after thymectomy.
