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.

PurposeArtifacts of metal implantation severely affect image quality of CT or MRI examination, which restricts the display of local soft tissue lesions after orthopaedic surgery. This study aims to explore the application value of ultrasound examination in local soft tissue lesions after metal implant surgery.Materials and Methods Seventy patients with metal implantation after various orthopedic surgeries received US examination, and such sonographic features were recorded as lesion morphology, size, internal echo, edge, with/without capsule and calcification, and blood flow. Moreover, the clinical and radiologic data of patients like X-ray, CT and MRI were compared with the US results so as to determine the sensitivity of ultrasonic examination.Results The peripheral nerve injury might lead to thickened swelling and echo reduction. Ultrasonography revealed 20 cases of hematoma formation, 5 cases of abscess, 5 cases of pseudoaneurysm, 3 cases of myositis ossificans, 15 cases of bone tumor recurrence and 12 cases of peripheral nerve injury in operative region. Compared with the clinical results , the sensitivity, specificity and accuracy of ultrasound diagnosis of the study reached 89.4%, 75.0% and 88.6%, respectively, which were signiifcantly higher than those of X-ray, CT and MRI (χ2=78.642, 46.596 and 61.371,P<0.01). The ultrasonic results showed that most hematomas had clear boundary with homogenous echo inside to echo-free zone. Abscesses mostly displayed cystic or hybrid echo with floatable intracavitary pus spots echo, and no blood flow signal existed in the central area of color Doppler. Pseudoaneurysm in the US showed cystic mass around artery, blood flow rotating in capsule, and the typical two-stage bi-spectrum signal in the neck of capsule. Myositis ossiifcans showed intramuscular irregular hyperecho with acoustic shadow. When bone tumor recurred, US showed hypoechoic soft tissue mass with moth-eaten bone destruction, and blood flow signals within the mass were often detected.Conclusion Ultrasonography has relatively high accuracy in observing soft tissues around metal implantation, which can be used as a premier method.

Self-efficacy is the extent or strength of one′s belief in one′s own ability to complete tasks and reach goals. Self-efficacy affects every area of human endeavor. By determining the beliefs a person holds regarding his or her power to affect situations, it strongly influences both the power a person actually has to face challenges competently and the choices a person is most likely to make. In this paper, the factors affecting self-efficacy, the effects of self-efficacy, the application range and interventions of self-efficacy in clinical disease management are reviewed. It has great significance in the improvement of ability of disease management,disease prognosis and quality of life by lifting the self-efficacy.

BACKGROUND:In oral warm and moisture circumstance, al oy which contains Be is easily to be eroded to release Be2+. But there is stil no research focusing on beryl ium influence on genotype of Porphyromonas gingivalis fimbriae gene cluster. OBJECTIVE:To investigate Be 2+effect on genotype of Porphyromonas gingivalis fimbriae gene cluster. METHODS:The revived Porphyromonas gingivalis was resuscitated for 48 hours in the anaerobic culture medium with different concentration of Be 2+(10×10-6, 5×10-6, 1.25×10-6). Through PCR amplification and sequencing, we investigated the effects of Be2+RESULTS AND CONCLUSION:(1) When Be on genotypes of Porphyromonas gingivalis fimbriae gene cluster. 2+concentration was 5×10-6, we found the peak of 217 and 257 sites on DNA sequence expressing G/A overlap peak, different from G single peak of the other groups, suggesting the suspicious bases changes, part of the single base G mutated into A. (2) On al concentrations, we found a base group composed of seven A bases was inserted into the 101 site of DNA sequence. Up to now, there is no direct contacts of the mutations occurring to Be2+concentration. Changes of gene may lead to the shifting of the reading frame, the abnormal synthesis of proteins, the change of Porphyromonas gingivalis fimA gene toxicity, and lastly the unbalance of the micro-ecological environment.

Objective To evaluate the clinical safety for outpatients over 80 years old after phacoemul sification surgery. Methods The 184 cases (226 eyes) of aged patients with cataracts were operated on with phacoemulsification and IOL implantation. The safety, complications during and after operation, visual recovery and others were followed up over that period. Results All eyes were operated on without any danger and no serious complications were found. The vision acuity was 0 5 or better in 198 cases (87 6%), 1 0 or better in 102 eyes (45 1%). The main complication was corneal edema in 58 eyes(26 2%), rupture of posterior capsule in 12 eyes (5 3%) and posterior capsular opacity in 16 eyes (7 1%). Conclusions The phacoemulsification and IOL for over 80 years outpatients were safe and effective. The key points are systemic physical examination and careful eye examination. Stimulations during operation and postoperative complications should be prevented.

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.
