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.

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.

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.

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 evaluate the clinical application of ultrasonic integrated backscatter(IBS) parameters and assess the lesion of myocardium in patients with different left ventricular geometric patterns.Methods Four groups were analyzed according to left ventricular mass index and relative wall thickness in 146 essential hypertensive patients,including group 1(n=64),group 2(n=18),group 3(n=20),group 4(n=44).Myocardial IBS,normalized IBS (IBS%),cyclic variation of IBS(CVIB) and transmural gradient of IBS(TGIB) of interventricular septum(IVS) and post wall(PW) were measured in 4 groups and 32 normal control subjects.Results Among the four groups,IBS% of IVS and PW were the highest in group 3 ( 53.6%? 9.8%, 52.8%? 8.3%,respectively) and next higher in group 2 ( 49.8%? 7.2%, 49.6%? 9.0%,respectively) and group 4 ( 49.0%? 7.7%, 48.9%? 8.2%,respectively),and was low in group 1 ( 42.3%? 8.4%, 41.8%? 9.1%,respectively) (P

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagnosis of congenital coronary artery fistula (CAF).Methods Thirteen consecutive patients ranging in age from 8 to 68 years underwent conventional transthoracic echocardiography,which depicts their origin, course, and drainage site. Results Right CAFs were detected in 8 patients: four of them had drainages to the left ventricle, two to the main pulmonary artery, one to the right ventricle(RV) and the other to the right atrium(RA). CAFs arising from the left coronary artery were noted in five patients: three of them had drainages to the main pulmonary, and the other two to the RA and RV respectively. The origin and the course were precisely defined and the drainage site was clearly depicted in all thinteen patients. The diagnosis of the thirteen patients was confirmed by coronary angiography, and eight of them received surgical treatment. Conclusions CDFI offers a simple, useful and reliable technique in diagnosis of CAF.
