Objective To investigate the clinical outcomes of patients with chronic hepatitis B and its influencing factors,and provide reference for the prognosis of patients with hepatitis B.Methods 102 patients with chronic hepatitis B from January 2009 to June 2014 were selected and divided into the case group of 32 patients and the control group of 70 patients according to whether to occur with cirrhosis or liver cancer.The two groups of patients were analyzed and compared for general information,HBV DNA,serum ALT and other indicators.Results The cumulative cases of negative HBsAg,chronical hepatitis B,liver cirrhosis and liver cancer were 5,65 and 32,respectively.Univariate Logistic regression analysis showed that the differences between the two groups in age,sex,drinking history,HBV DNA levels and serum ALT levels were statistically significant (all P ＜ 0.05).Whether to cirrhosis or liver cancer was the dependent variable,the statistically significant single factors between the two groups were the independent variable,multivariate Logistic regression analysis showed that older age,male sex,alcohol abuse,high level of HBV DNA and high level of serum ALT were the risk factors of leading to cirrhosis,liver cancer for the patients with chronic hepatitis B (OR values were 9.94,14.36,8.25,13.01,120.32,respectively).Conclusions The older age,male,alcohol history,high level of HBV DNA and high level of serum ALT are higher risk factors for patients with chronic hepatitis B to development of cirrhosis and liver cancer.Patients with risk factors should be gave systematic interventions to reduce progression to cirrhosis,liver cancer and improve the quality of life.

With the appearance of new biological agents represented by infliximab,the medical therapy of crohns' disease has made breakthrough of progress.However,the controversial still remains about the use of infliximab during perioperative period in Crohn's disease patients.The aim of this article is to explore the influence of infliximab on postoperative complications in Crohn's disease patients.

Consuming an adequate amount of iodine during pregnancy is critical for fetal neurologic development.Even a mild deficiency can impair cognitive ability.The World Health Organization recently has increased their recommended iodine intake during pregnancy from 200 to 250 μg/d and suggested that a median urinary iodine concentration of 150 ～ 249 μg/L indicates adequate iodine intake in pregnant women.Whether mild-to-moderate maternal iodine deficiency produces more subtle changes in cognitive function in offspring is unclear;no controlled intervention studies have measured long-term clinical outcomes.This review summarizes the iodine nutrition of pregnant women,and the effects of iodine deficiency in pregnancy on neurodevelopment in the child.To prevent fetal damage,iodine should be given before or early in pregnancy.

Failure to deliver sufficient oxygen to the tissues and failure to utilize oxygen in the tissues are essential pathophysiological changes in circulatory failure situations.This is common in all kinds of shocks.Monitoring oxygen delivery and metabolism not only changes the ways to assess the shock but also affects the managements of shocks deeply.Monitoring and controlling global and tissue oxygen delivery and metabolism are goals for circulatory failure assessment and management in the future.

Objective To explore the effects of minimally invasive technique in the treatment of lumbar spinal stenosis.Methods 80 lumbar spinal stenosis patients were divided into the observation group and control group,40 cases in each group,who were informed consent under the premise of the stochastic averaging grouping.The two groups were treated with microscopic invasive technology and traditional posterior bilateral fenestration decompression,and the therapeutic effect of two groups were compared.Results The average operation time of the observation group (36.2 ± 4.1) rain was obviously shorter than that of the control group (41.4 ± 5.7) min (t =2.719,P ＜ 0.05) ; the average amount of bleeding of the observation group (51.6 ± 7.3) ml was significantly lower than that of the control group(101 ± 11.7) ml(P ＜ 0.05) ; the two groups of patients before treatment JOA score had no significant difference after treatment,follow-up,JOA scores of the two groups increased significantly,the observation group increased significantly compared with the control group (P ＜ 0.05) ; the treatment group 19 cases of excellent,good in 17 cases,the excellent and good rate was 90％,control group 13 cases of excellent,good in 16 cases,the excellent and good rate was 72.5 ％,the treatment group was better than the control group (x2 =6.594,P ＜ 0.05) ; the observation group did not appear obvious postoperative complications occurred in 3 cases,the control group of nerve root injury,1 cases of intervertebral space infection,2 cases of incision leakage,the incidence of complications was 15％,observation complication rate was significantly lower than that of the control group (x2 =3.357,P ＜ 0.05).Conclusion The microscopic invasive technique for the treatment of lumbar spinal stenosis has a good curative effect,small trauma,high safety,which is conducive to improve the prognosis of patients,can gradually replace the traditional posterior bilateral fenestration decompression.
