Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disorder, and the carriers of DMD can suffer from cardiac damage without muscle weakness, which can predispose to death. Consequently detecting and preventing cardiac damage in the early stage can improve the carriers' quality of life. The detection of early cardiac abnormalities and the evaluation of cardiac function for carriers mainly rely on the different examination methods, including electrocardiogram, echocardiogram, cardiovascular magnetic resonance, radioactive nuclide myocardial perfusion imaging and coronary angiography. Carriers of DMD with cardiac damage are assessed by different examination methods in different ways.

Human T-cell leukemia virus type 1 (HTLV-1) is a retrovirus demonstrated to be associated with human disease. Infection by the HTLV-1 can cause T-cell leukemia (ATL) in adults. HTLV-1 bZIP factor (HBZ) is a viral protein encoded by the minus strand of the HTLV-1 provirus. Among the regulatory and accessory genes of HTLV-1, HBZ is the only gene that remains intact and which is expressed consistently in all patients with ATL. Moreover, HBZ has a critical role in the leukemogenesis of ATL. Here, we review the function of HBZ in the oncogenesis of HTLV-1 and its molecular mechanism of action.

UL48 plays essential role in replication of MDV genome and interacts with UL36 as well as other MDV tegument proteins.To investigate the interaction between UL48 and UL36 during MDV oncogenisis,antibody against UL48 was prepared and characterized in current study.UL48 gene was amplified from MDV-Ⅰ genome and then subcloned into pTYB1 and pGEX-4T3 vectors for UL48 expression with induction of IPTG in BL21(DE3) E..coli cells.Chitin-sepharose and Glutathion-sepharose were,respectively,used to purify fusion protein intein-UL48 and GST-UL48.Four subcutaneous injections of intein-UL48 fusion protein were done on the lower back and the thigh of rabbit and then other three injections with an interval 10 days.The titer of antibody was measured by the sandwich ELISA with UL48 protein isolated from GST-UL48 after cleavage of thrombin.Western blot was carried out for specificity analysis of antibody against UL48 protein.The results suggested that UL48 antibody was succesfully prepared,and its titer was 1 ∶ 512 000.

Objective: To explore the mediating role of empowerment level in self-management and quality of life in patients with coronary heart disease, and to provide evidence for interventions to improve quality of life in patients with coronary heart disease. Methods: 215 patients with coronary atherosclerotic heart disease in cardiovascular department of hospital in Dalian were selected as the subjects. The Chronic Empowerment Scale, Self-management Behavior Scale of Coronary Heart Disease, China Cardiovascular Patient Quality of Life Assessment Questionnaire and self-made general information questionnaire were used for investigation. Results: The total empowerment, self-management and quality of life of patients with coronary heart disease were (158.75±20.39), (74.50±11.55), and (73.31±23.01). The empowerment, self-management and quality of life of patients with coronary heart disease were positively correlated (r=0.512-0.642, P<0.01). Self-management has a direct positive predictive effect on quality of life. The level of empowerment has a partial mediating effect between self-management and quality of life, and the contribution rate of mediating effect was 31.5%. Conclusions Empowerment, self-management and quality of life of patients with coronary heart disease are closely related. Self-management can influence the quality of life through the empowerment. Nurses should develop active and effective empowerment programs to improve patients' self-management ability and their quality of life.

Kinetin (Kn) is a cytokinin growth factor that exerts several anti-aging and antioxidant effects on cells and organs. To investigate the mechanism underlying apoptotic events in aging cells induced by D-galactose (D-gal), we examined the effect of Kn delivered via nuchal subcutaneous injection on D-gal-induced aging and apoptosis in rats. Our results showed that interleukin (IL)-2 levels and mitochondrial membrane potential (DeltaPsim) were decreased by Kn in aging rats while IL-6 production and apoptosis increased. In addition, the expression of anti-apoptotic Bcl-2 was low while that of Bax was high in the aging group. After treated with Kn, compared with aging group, there showed obvious difference in Kn group with elevated IL-2, proliferation index, Bcl-2, DeltaPsim and decreased IL-6 and Bax in splenic lymphocyte. Based on these results, we concluded that Kn can effectively protect the rat spleen from aging, apoptosis, and atrophy.

Objective:To investigate the relationship between uncertainty in illness, coping with adaptive ability and psychological stress response among patients in Emergency Observation Room, and to provide reference for reducing the psychological stress level of patients.Methods:Questionnaire survey was conducted on 260 patients in Emergency Observation Room in a third-grade hospital in Dalian using the general data questionnaire, the Chinese version of the Mishel’Uncertainty in Illness Scale, the Chinese version of the Coping Adaptation Processing Scale and the Stress Response Questionnaire.Results:Coping with adaptive ability played a part in mediating the relationship between uncertainty in illness and psychological stress among patients in Emergency Observation Room. The mediating effect accounted for 32.23% of the total effect. Coping with adaptive ability can reduce the positive reinforcement effect of uncertainty in illness on psychological stress response through emotional and behavioral response pathways.Conclusions:Uncertainty in illness can directly or indirectly affect the psychological stress response of by responding to coping with adaptive ability. It can reduce the influence of psychological stress response on patients' psychosomatic function by reducing the uncertainty in illness and improving the ability to cope with adaptation.

The development of liver inflammatory diseases is associated with autoimmunity and inflammatory response. As a negative feedback regulator of cell signal, suppressor of cytokine signaling 1 (SOCS1) plays a key role in the development and progression of inflammatory diseases. This article mainly introduces the mechanism of action of SOCS1 in autoimmunity and inflammatory response and briefly describes its role in the development and progression of liver inflammatory diseases such as viral hepatitis and nonalcoholic steatohepatitis. The analysis shows that the abnormal expression of SOCS1 in inflammatory response is associated with the regulation of cytokine receptor, Toll-like receptor, and hormone receptor signal, which leads to the development of inflammatory diseases. Therefore, SOCS1 has potential prospects as an auxiliary means for the diagnosis and treatment of liver inflammatory diseases.
