Objective:To investigate the effect of free fatty acid on leptin receptor in rats.Methods:High plasma free fatty acid rat model was created by intravenous injection of free fatty acid. Western blot was used to assess the protein level of leptin-receptor in rat liver, muscle and pancreas tissues. The RNA expression level of leptin-receptor was examined by RT-PCR .The tyrosine phosphorylation of leptin-receptor was examined by immuno-precipitation. Results:The protein and RNA levels of leptin-receptor in liver,muscle and pancreas tissues of high plasma free fatty acid rats were similar to those of normal group(P>0.05).But the tyrosine phosphorylation of leptin-receptor significantly downregulated in liver and muscle tissues as compared with control group(P<0.05). Conclusions:High plasma free fatty acid may affect the tyrosine phosphorylation of leptin-receptor in rat liver and muscle.

Objective To analyze the mierosurgery treatment and prognosis of cavernous hemangioma loca-ted in pons. Methods 12 cases with cavernous hemangioma located in ports underwent mierosurgery. 11 lesions lo-cated in dorsal tons were resected through midline suboccipital trans- rhomboid fnssa approach. 1 lesion located in ventrolateral pous was resected with suboceipital retrosigmoid approach. Results All the 12 cavernous hemangiomns were rosected totally and confirmed by the postoperative pathology. Clinical improvement was gained in 6 cases, no change in 3 ,aggravation of facial palsy in 1 ,death in 1. The mean follow-up time was 3 months,and Mill scan dem-onstrated good restoration of brain stem tissue with no recurrence signs of lesion. The symptoms due to the operation recovered to some extent. Conclusion The cavernous hemangioma located in brain stem can be resected safely and effectively given the selection of surgical indication and optimal surgical approach.

This study is to investigate the binding capability of lidamycin apoprotein (LDP), an enediyne-associated apoprotein of the chromoprotein antitumor antibiotic family, to human breast cancer and normal tissues, the correlation of LDP binding capability to human breast cancer tissues and the expression of tumor therapeutic targets such as VEGF and HER2. In this study, the binding capability of LDP to human breast cancer tissues was detected with tissue microarray. The correlation study of LDP binding capability to human breast tumor tissues and relevant therapeutic targets was performed on breast cancer tissue microarrays. Immunocytochemical examination was used to detect the binding capability of LDP to human breast carcinoma MCF-7 cells. As a result, tissue microarray showed that LDP staining of 73.2% (30/41) of breast cancer tissues was positive, whereas that of 48.3% (15/31) of the adjacent normal breast specimens was positive. The difference between the tumor and normal samples was significant (Chi2 = 4.63, P < 0.05). LDP immunoreactivity in breast cancer correlated significantly with the overexpression of VEGF and HER2 (P < 0.001 and < 0.01, r = 0.389 and 0.287, respectively). Determined with confocal immunofluorescent analysis, LDP showed the binding capability to mammary carcinoma MCF-7 cells. It is demonstrated that LDP can bind to human breast cancer tissues and there is significant difference between the breast cancer tissues and the corresponding normal tissues. Notably, the binding reactivity shows positive correlation with the expression of VEGF and HER2 in breast carcinoma tissues. The results imply that LDP may have a potential use as targeting drug carrier in the research and development of new anticancer therapeutics. This study may provide reference for drug combination of LDM and other therapeutic agents.

Objective To observe the effect of gheocorticoid by oral medication or intrathoracic iniection on the expression of IL-6,IL-8 and sIL-2R in gerum and pleural fluid in patients of tuberculous pleurisy.Methods Twenty tuberculous pleurisy patients were treated with ghcocortieoid by oral medication (oral group)and 20 cases by intrathoracic injection(injection group).ELISA wag employed to detect the levels of IL-6,IL-8 and sIL-2R in serum and pleural fluid before treatment and 3,6 and 9 days after treatment.Results The levels of serum IL-6 and IL-8 decreased and sIL-2R increased obviously in injection group at 3,6 and 9 days after treatment(P＜0.01).Meanwhile the levels of IL-6 and IL-8 in pleural fluid decreased and sIL-2R increased obviously(P＜0.01).The levels of IL-6 and IL-8 were significantly lower and the levels of aIL-2R were significantly higher in injection group than those in oral group(P＜0.01).One month after treatment,the rate of complete absorpion of pleural fluid was higher in injection group(80%)than thatin oral group(45%),the rate of pachynsis pleurae was lower in injection group(10%)than that in oral group(40%),P＜0.05.Conclusions Intrathoracic injection of ghcocorticoid shows stronger suppression of cellular immune function in cavum pleurae and weaker suppression of the general immune sysmm than oral medication.Intrathoracic injection of glucocorticoid can increase the therapeutic effect and decrease side effect in tuberculous pleurisy.

Objective To investigate the influence of a multifaceted stroke telehome-care (THC) on extremities function, activities of daily living (ADL) and quality of life in stroke patients with hemiplegia. Methods A total of 52 stroke survivors in department of neurology were randomized to the THC intervention or usual care. The patients in the control group received conventional care, while those in the intervention group were additionally given a THC program over 3 months. The THC intervention includes motor imagery and adaptive strategies. Data collection was undertaken using the Fugl-Meyer Motor Assessment Scale (FMA), the Barthel Index (BI), the Stroke Impact Scale (SIS) at baseline, 3 months, and 6 months. Results At baseline, the scores of FMA, BI, and SIS in the intervention group were 53.62 ± 23.52, 54.04 ± 17.44, 179.96 ± 28.51, and while the scores of the control group were 50.96 ± 19.52, 49.46 ± 15.09, 169.23 ± 28.48. There were no pre-existing differences on any scale between the two groups (t=0.443, 1.012, 1.358, P > 0.05). At 3 months, the scores of FMA, BI, SIS in the control group were 53.54 ± 17.45, 50.77 ± 14.47, 76.19 ± 27.78, and were significantly lower than 78.38 ± 12.54, 74.62 ± 11.22, 228.54±22.63 in the THC group (t=5.895, 6.641, 7.449,P<0.01). At 6 months, the scores of FMA, BI, SIS in the control group were 57.88±17.89, 59.08±13.85, 183.92±26.56, and were significantly lower than 90.58 ± 9.60, 86.54 ± 9.88, 252.19 ± 20.10 in the THC group (t=8.211, 8.233, 10.451, P < 0.01). Conclusions A telehome-care program that provide distance training and education of disabled persons resulted in greater improvements in physical functioning, ADL and quality of life.

Objective To investigate the status of anxiety,depression and self-efficacy, social support among patients with severe burns and analyze their correlation. Methods Eighty-four patients with severe burns were selected by convenience sampling. They were evaluated by Hospital Anxiety and Depression scale (HADS), General Self-efficacy Scale (GSES) and Social Support Assessment Scale (SSAS) and the correlation of two scales was analyzed. Results The anxiety score was 6.62 ± 3.98, depression score was 7.63 ± 4.36, self-efficacy score was 20.94 ± 4.96 and the social support score was 41.40±6.47;Self-efficacy was negatively correlated with the anxiety (r=-0.356, P<0.05) and depression (r=-0.362, P<0.05). Social support was also negatively correlated with the anxiety (r=-0.305, P<0.05) and depression (r=-0.320, P<0.05). Conclusions There is a medium level of anxiety and depression among patients with severe burns. Psychological interventions via increasing the self- efficacy are suggested for the patients with severe burns in the future.
