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 explore the relationship betwwen the different types of ischemic cerebrovascular disease andthe levels of plasma Homocystine(Hcy).Methods:The levels of plasma Hcy in 135 patients with ischemic cerebrovascular disease were measured by the fluorometric method.All the patients were divided into transient ischemic attack(TLA)group and atherothrombotic cerebral infarction(ACO group.The patients in both groups and the levels of plasma Hcy between the primary ACI and recurrent ACI were compared.Results:The levels of plasma Hcy in the ACI group(22.0±6.4 μmol/L)group were significantly higher than those in the TIA group(16.6±6.0 μmol/L)(P<0.01),and the levels of plasma Hcy in the recurrent ACI group(23.0±5.5 5 μmol/L)were significantly higher than those in the primary group(19.6±5.9 μmol/L)(P<0.01).There were rio significant differences between the two groups in age,sex,history of smoking.lipid,body mass index,as well as the prevalences of hypertension,diabetes mellitus and coronary heart disease.Conclusions:The increased level of plasma Hcy is closely associated with ACI.and it is a risk factor for recurrent stroke.

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 effect of home-based motor imagery training on the lower extremity motor function,balance ability and activities of daily living in post-stroke patients. Methods Fifty-six stroke survivors were divided into the control group and the intervention group by random number table method.All the patients got the conventional nursing, rehabilitation booklets and the video tapes which contained physical therapy and occupational therapy. Furthermore, the patients in the intervention group received 6 weeks motor imagery (MI) therapy through an instant messaging client (Tencent QQ), three times a week, 30mins per time. The outcomes were measured before discharge (T0), immediately after the intervention (T1), and 6 weeks (T2) after the intervention using the Fugl-Meyer Motor Assessment Scale (FMA), Berg Balance Scale (BBS), Barthel Index (BI). Results At baseline, the scores of FMA、BBS、BI in the intervention group were (15.12 ± 4.19), (24.50 ± 2.72), (54.04 ± 17.44) points, while in the control group were (14.23 ± 3.67), (23.92 ± 2.82), (49.46 ± 15.09) points. There were no differences on any scale between the two groups at baseline (t=0.810, 0.750, 1.012, P>0.05). At 6 weeks,the scores of FMA, BB, BI in the control group were (14.81 ± 3.50), (29.31 ± 2.43), (50.77 ± 14.47) points, and were significantly lower than (17.38 ± 4.10), (37.38 ± 4.30), (74.62 ± 11.22) pointsin the interventiongroup (t=2.438, 8.326, 6.641, P<0.05 or 0.01). At 12 weeks, the scores of FMA, BB, BI in the control group were (15.54±3.44), (32.35±1.98), (59.08±13.85) points, and were significantly lower than (18.58±4.19), (41.19±3.96), (86.54± 9.88) points in the intervention group (t=2.858, 10.189, 8.233, P<0.01). A main effect of intervention (F=4.158, 63.716, 30.379, P < 0.05) and an interactive effect of time and intervention (F=47.941, 61.029, 29.685, P=0.000) were observed in the model of FMA, BBS, BI using ANOVA of repeated measures. The factors were compared with each other and the difference was statistically significant (P=0.000). Conclusions The home-based MI training can improve the lower extremity motor function, balance ability and activities of daily living in patients with stroke.

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.

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.
