Objective To explore clinical haracteristics, diagnosis, treatment, prognosis and prevention of mental disorder induced by interferon.Methods Thirty cases of interferon treatment for chronic hepatitis were select-ed as research subjects.The psychotic symptoms of these patients induced by interferon were analysized by clinical statistics.Results The Self-Rating Depression Scale( SDS) and the Self-Rating Anxiety Scale( SAS) scores after treatment were (47.10 ±9.47) points and (43.00 ±10.34) points,these were higher than before treatment and the difference was statistically significant (t=8.39,7.66,all P<0.01).The incidence rates of the psychotic symptoms in this group of interferon-induced were 66.7%(20/30).The occurrence rates of headaches,insomnias,depres-sions,anxieties and personality changes were respectively 36.7%,30.0%,16.7%,10.0%,10.0%.Before and after treatment,the difference was statistically significant (χ2 =15.43,P<0.01).Conclusion The symptoms of mental disorder induced by interferon have high incidence rate and serious consequences,so early detection and early treat-mentcan contribute a better prognosis.

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.

Hepatocellular carcinoma (HCC) is a malignant tumor with high incidence and mortality rates around the world.Radiofrequency ablation (RFA) is an effective therapy for HCC,especially in patients who experience recurrence after surgery for liver cancer,who are complicated by liver dysfunction and unable to undergo surgical resection,and who have multiple liver tumors and undergo palliative treatment.RFA can significantly improve patients' survival time and quality of life.This article reviews the mechanism of RFA in the treatment of HCC from the aspects of direct and indirect injuries and helps to further understand the role of RFA in local and systemic treatment of HCC,which has a potential value for multidisciplinary treatment of HCC in future.

Pediatric hypertrophic cardiomyopathy (PHCM)is a heterogeneous heart muscle disorder which is characterized by unexplained ventricular hypertrophy.Successful determination of a specific diagnosis is likely to have significant impact on management and survival because of the differences in etiology-specific sur-vival.This review provides an overview of PHCM with a focus on its etiology and their heart features.

Objective:To explore the application of fetal multi-organ hemodynamics in the detection and evaluation of oxygen supply and blood supply for fetus in the third trimester of pregnancy. Methods: 42 pregnant women with gestational diabetes mellitus and 42 healthy pregnant women were divided into observation group and control group, respectively. All of the fetuses of pregnant women received Doppler ultrasound examination, and the pulsatility index(PI), resistance index(RI) and systolic/diastolic(S/D) ratio of umbilical artery (UA)and middle cerebral artery (MCA) of every fetus in the two groups were observed. Besides, the number of fetal distress was recorded and the relationship between fetal distress rate and gestational diabetes mellitus were calculated.Results:The PI, RI and S/D of MCA of fetuses of pregnant women with gestational diabetes mellitus was significantly higher than that of healthy pregnant women (t=7.52,t=6.04, t=8.69,P<0.05). And the PI, RI and S/D of UA of fetuses of pregnant women with gestational diabetes mellitus also was significantly higher than that of health pregnant women (t=11.95,t=9.78,t=8.95, P<0.05). Besides, the fetal distress rate of observation group was significantly higher than that of control group (x2=19.56,P<0.05).Conclusion: The fetal blood flow information which obtained from Doppler ultrasound has very importantly value in the diagnosis of gestational diabetes mellitus, and it verifies the relationship between fetal distress rate and gestational diabetes mellitus. It provides beneficial basis for the prevention and treatment of the gestational diabetes mellitus in the clinical practice.

Objective To investigate the effects of exercise on the activity of heme oxygenase-1 ( HO-1 ) and the expression of HO-1 mRNA and the mechanisms involved in the vascular smooth muscle tissue of rats with spontaneous hypertension (SHR). Methods Twelve male Wistar rats with normal blood pressure were used as control group ( group C ).Another 24 male rats with SHR were randomly assigned to one of 2 experimental groups ( 12 rats per group):an SHR group (group S) and an SHR treated group (group T).Rats in group T were treated with 60 minutes of unloaded swimming exercise 6 times a week for 9 weeks.Their blood pressure was measured once a week.After the nine weeks HO-1 activity as well as the expression of HO-1 mRNA in vascular smooth muscle and the concentration of carbon monoxide in plasma were measured. Results After the 9 weeks of training,average systolic blood pressure in group T was close to that of group C.The systolic blood pressure of group S continued to rise,and was significantly higher than that of the other 2 groups at each time point.Average HO-1 activity in group S (637.94 ± 73.637 ) reduced significantly compared with that of group C (786.20 ± 74.698) or with that of group T ( 1036.53 ± 140.63 ).That of group T was significantly higher than that of group C.The average expression of HO1 mRNA in group S (80.85 ± 6.953 ) was significantly higher than that of group C (45.15 ± 7.651 ) and lower than that of group T (90.70 ± 11.20),and the differences were statistically significant at the 5％ level of confidence.The average level of expression of HO-1 mRNA in the T group was significantly higher than that of group C.The plasma carbon monoxide content of S group was significantly lower than that of groups C and T. Conclusions Exercise can enhance the activity of HO-1 and the expression of HO-1 mRNA in vascular smooth muscle in rats with SHR to reduce blood pressure.
