Leptin,the product of the obese gene,is a 16kDa secreted protein produced by white adipocytes.Because of its dual nature as a hormone and cytokine,leptin plays a role in regulating energy metabolism,inflam-marion,immune response,neuroendocrine and angiogenesis,and so on.The review focuses on the research and controversy of leptin's effect in osteoarthritis.

Objective To explore the morphology changes of spinal cord after nursing intervention on motor function repair spinal cord injuried rats. Methods 60 adult SD rats were randomly divided into normal control group, experimental control group, and experimental group ( n=20 for each group) . Each group were divided into four time phase points, that is 1 day, 7 days, 30 days and 60 days after spinal cord injury (n=5). The model of L4 plane with full transection of spinal cord were made in the rats in experimental control group and exper-imental group. Normal control group were of untreated normal rats, experimental control group were given routine nursing such as urination and defecation after spinal cord injury, and experimental group were given passive movement practices and muscle massage training twice a day (10 min each time) besides regular nursing. HE staining and immunohistochemistry method were applied to observe the morphology changes of spinal cord. Results In experimental control group and experimental group there was no significant changes in HE staning and NF-200 and GFAP immunohistchemistry staning in spinal cord section of rat at each time phase points, but compared to the normal control group, it was of significant difference. Conclusion There is no apparent change in morphology in injured spinal area after nursing intervention.

Objective To explore the effect of nursing intervention on degree of motor function recovery after spinal cord injury in rats. Methods 60 rats were randomly divided into three groups with 20 rats in each group. Group A was the control group,group B was the rou-tine nursing group,and group C was the nursing intervention group which was given nursing intervention such as muscle pressure,joint passive movement,and skin care. The ethology was evaluated by BBB score and inclined-plane score at different time points after spinal cord injury. Myoelectricity and wet weight of gastrocnemius muscle were observed at different time points after spinal cord injury through multi-channel physiological signal acquisition system and electronic weighing scales. Results BBB score and inclined-plane score were basically the same. Compared with group B,hind limb function of group C was significantly improved,but it was obviously lower than the control group. Amplitude of gastrocnemius myoelectrical fibrillation in group C was higher than that in group B and gastrocnemius muscle wet weight decrease in group C was lower than that in group B. Conclusion Nursing intervention can delay the speed of gastrocnemius muscle atrophy,improve motor function,and promote the recovery of partial function after the spinal cord injury in rats.

Non-receptor tyrosine kinase c-Abl has been implicated in the regulation of the cell cycle,adhesion, apoptosis and DNA damage responses.Its excessive activation is related with the development of chronic myeloid leukemia, and the relationship between c-Abl and leukemia is in depth and detailed research.In contrast to leukemia, the research between c-Abl and solid tumors is just at the early stage.This paper briefly reviews research progress of the c-Abl in solid tumors.

OBJECTIVE: To investigate the therapeutic effects of 768 coblation treatment in children with obstructive sleep apnea-hypopnea syndrome. METHOD: A review of 768 coblation treatment in children with obstructive sleep apnea-hypopnea syndrome was presented with respect to the sleep monitoring results, therapeutic effects and complications. RESULT: The time of pseudomembrane ablate was 10-14 d after operation. There were 11 patients occurred Secondarily bleeding within 1 week and 21 patients lymphatic tissue hyperplasia compensatorily within half a year after operation. After operation 3 months, the sleep Monitoring results were improved remarkably (P < 0.01) and the symptoms of snore and choke improved. CONCLUSION Coblation treatment in children with obstructive sleep apnea-hypopnea syndrome can reduce bleeding volume and improve obstruct syndrome apparently. The treatments of tonsils and adenoids differ with the characteristics of children and tympanotomy was fit for chil dren with secretory otitis media.

Objective To explore the variation of serum galectin-3 and its correlation with ventricular remodeling in children with chronic cardiac failure (CHF). Methods Forty-ifve children with CHF were included and divided into cardiac function II group (n=10 ), III group (n=18 ), and IV group (n=17 ) according to the severity of CHF. The subjects were also divided into endocardial fibroelastosis (EFE) group (n=21 ) and dilated cardiomyopathy (DCM) group (n=24 ) according to primary disease. Thirty health children were included as control group. The level of serum galectin-3 was detected by ELISA. The level of serum NT-pro BNP was measured by radio immunoassay. The index of ventricular remodeling was detected by ultrasonic cardiogram. The correlation of the level of serum galectin-3 with ventricular remodeling and the level of serum NT-pro BNP were analyzed. Results In 45 children ( 19 males and 26 females) with CHF, the mean age was 3 . 42 ± 1 . 89 years. The levels of serum galectin-3 and NT-pro BNP were higher in cardiac function II group, III group, and IV group than those in control group (all P?0 . 05 ). Spearman rank correlation analysis showed that the level of serum galectin-3 was positively correlated with the left ventricular end diastolic diameter, the left ventricular mass, the left ventricular mass fraction, and the level of serum NT-pro BNP (all P?

Epidermal growth factor receptor (EGFR), an important target for tumor targeted therapy, is overexpressed / mutated in the majority of tumors. Immune cells modified by chimeric antigen receptor , including T cells, NK cells and so on, is a new technology in recent years, which has showed an unique advantage in the treatment of malignant tumors. In this paper, the research progress of T cells and NK cells modified with chimeric antigen targeting for EGFR and its mutants will be reviewed.

Objective To study the clinical significance of the content of ? 2-microglubin and activity of ?-glucuronidase in cerebrospinal fluid (CSF) of patients with cerebral tumor. Methods The activities of ? 2-microglubin and ?-glucuronidase in CSF of patients with cerebral tumor and non- cerebral tumor were analyzed by radioimmunoassay and enzyme-linked immunosorbent assay (ELISA) respectively. Results the activities of ? 2-microglubin and ?-glucuronidase in cerebral malignancy were obviously higher than that of cerebral benign tumor (P

Objective To investigate the effect and mechanism of Jinkuishenqi wan (JGSQ) on pulmonary fibrosis. Methods Pulmonary fibrosis was induced by bleomycinA5 in SD rats. Rats in treatment group were killed after being treated by JGSQ daily for 28 days. The lungs of all rats were harvested for histopathological studies. The contents of transforming growth factor-?_1 (TGF-?_1) in lungs were measured and compared. Results The contents of TGF-?_1 in lungs increased significantly in model group as compared with normal group and treatment group (P
