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.

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 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.

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

Objective To study the radiographic findings of lymphoproliferative disorders of the lung. Methods Twenty five patients with lymphoproliferative disorders of the lung were examined by X ray film, tomography, and CT. Results Multiple and mediastinal lymphadenopathy were observed in 2 patients with pulmonary pseudolymphoma. Multiple nodules or masses were observed in 4 patients with pulmonary lymphomatoid granulomatosis. Hilar and mediastinal lymphadenopathy was observed in each patient with angioimmunoblastic lymphadenophathy, 2 patients had multiple nodules or masses, 8 patients had single or multiple patchy infiltrations, 10 had diffuse interstitial infiltrations. 3 patients with Castlemen′ disease had a mass in the mediastinum, and another patient had mediastinal lymphadenopathy. Conclusion Radiographic findings of lymphoproliferative disorders of the lung are varied, and the final diagnosis relies on pathology.

Objective　To study the radiographic findings in the diagnosis of pulmonary lymphoma and pseudolymphoma. Methods　Eight patients with pulmonary lymphoma and 2 with pseudolymphoma were examined by X-ray film, tomography, and CT. Results　Single or multiple nodules or masses were observed in 8 patients with pulmonary lymphoma, shaggy borders or halo of ground-glass attenuation in 7 patients, 2 patients had multiple patchy infiltrates bilaterally, 2 had diffuse interstitial infiltrates and 1 had miliary nodules. Multiple consolidations with air bronchogram and without hilar and mediastinal lymphadenopathy were observed in 2 patients with pulmonary pseudolymphoma. Conclusion　Radiographic findings of pulmonary lymphoma were varied, the most common findings were the nodules or masses with shaggy borders or halo of ground-glass attenuation. The specific findings of pulmonary pseudolymphoma were multiple consolidations with air bronchogram and without hilar and mediastinal lymphadenopathy. The final diagnosis relied on pathology.

Objective To investigate the effect of informational support on disease uncertainty in liver cancer patients undergoing interventional therapy. Methods Sixty patients of liver cancer patients undergoing interventional therapy were randomly divided into the intervention group and the control group with 30 in each.The control group was treated with general treatment and care. The patients in the intervention group were given general treatment and care with a series of informational support interventions. Patients in the two groups were measured by uncertainty in illness scale (MUIS) at the day of admission,before operations and discharged from hospital. The measurement results were statistically analyzed. Results There was significant decrease about disease uncertainty scores both on the day before operation and the day before discharge in the intervention group compared to the day of admission. The decreasing score of uncertainty in illness in the intervention group was significantly greater than the control group on the day before operation and the day before discharge. Conclusions A series of informational support interventions could significantly reduce the diseases uncertainty in liver cancer patients undergoing interventional therapy.

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
