[ ABSTRACT] AIM:To establish the insulin resistance rat model for evaluating the correlation of omentin-1 level and insulin resistance.METHODS: SPF male Wistar rats ( n =30 ) were randomly divided into normal control group (NC, n=15) and high-fat diet group (HF, n=15).The rats in NC group were fed with basic diet.The insulin resistant model was established by feeding the rats with high-fat diet in HF group.After 10 weeks, 5 rats in each group were as-sessed by the technique of hyperinsulinaemic-euglycaemic clamp.After the insulin resistant model was successfully estab-lished, the body weight and fasting blood glucose were detected.The concentration of fasting serum omentin-1 was analyzed by ELISA.Fasting serum insulin was measured by radioimmunoassay.RESULTS: No difference of fasting blood glucose between the 2 groups was observed.The level of fasting serum insulin in HF group was significantly higher than that in NC group ( P <0.05 ) .The level of serum omentin-1 in HF group were significantly decreased compared with NC group (P<0.01).Pearson’s correlation analysis showed that negative correlations between serum omentin-1 and fasting serum insulin (r=-0.654,P<0.01), serum omentin-1 and free fatty acid (r=-0.446, P<0.05) was found.CONCLU-SION:In rats, serum omentin-1 level began to decrease at insulin resistance stage.As serum omentin-1 level decreased, the basal insulin level increased, indicating that decreased serum omentin-1 level may be an early factor of IR, diabetes and cardiovascular diseases.

Objective To investigate the clinical effects of bioglue compound and anatomic plate in treatment of tibial plateau fractures. Methods 28 cases of tibial plateau fractures were treated by means of open reduction and internal fixation with bioglue compound and anatomic plate. The intervals between operation and injury ranged from 5 to 10 days. The amounts of bioglue compound implanted ranged from 3 to 8 grams. Results All the patients were followed up for 6 to 22 months. All the fractures healed satisfactorily without sunken joint surface. According to Mechant criteria, the result was excellent in 13 cases, good in 11 cases, moderate in 3 cases and poor in 1 case. The total excellent and good rate was 85.3 %. Conclusion Internal fixation with bioglue compound and anatomic plate can result in good effects in treatment of tibial plateau fractures, because the bioglue compound possesses high bone inductive potentialities to repair bone defects.

Objective To investigate the application and effect of aerobic exercise of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD).Methods Ninety-four hospitalized patients with COPD from June 2011 to June 2012 were enrolled.The clinical curative effect and safety of aerobic exercise of pulmonary rehabilitation in patients with COPD were observed and compared.Results After 3 months treatment,first second forced expiratory volume (FEV1) and forced vital capacity (FVC) were increased compared with those before treatment [(3.25 ± 0.49) L vs.(2.59 ± 0.55) L,(1.95 ± 0.41) L vs.(1.44 ± 0.48) L],and there were significant differences (P ＜ 0.05).There was no significant difference in FEV1/FVC before and after treatment (P ＞ 0.05).After 3 months treatment,arterial partial pressure of oxygen and arterial oxygen saturation were increased compared with those before treatment [(87.61 ± 8.56) mm Hg(1 mm Hg =0.133 kPa) vs.(63.88 ± 8.79) mm Hg,0.9648 ±0.0449 vs.0.7632 ± 0.0477],partial pressure of arterial carbon dioxide was decreased compared with that before treatment [(30.57 ± 9.47) mm Hg vs.(49.23 ± 9.54) mm Hg],and there were significant differences (P ＜ 0.05).There was no signifi.cant difference in blood pressure and heart rate before and after treatment (P＞ 0.05).No obvious adverse reactions were observed.Conclusions The aerobic exercise of pulmonary rehabilitation can improve significantly lung function.It is safe and rehable,and has less adverse reaction in patients with COPD.It is worthy of promotion and use.

Objective To evaluate the characteristics of left ventricular systolic longitudinal strain in uremic patients and its relationship with dialysis time using three-dimensional speckle tracking echocardiography (3D-STE).Methods Forty-six uremic patients were divided into three groups according dialysis time (ranged 0-5 years):group A (≤1 year),group B (1 year＞time ≤3 years),group C (3 years ＞time≤5 years),group D was control group.The dynamic images of apical four chamber view were displayed and apical full-volume images were obtained and saved in all subjects using a full volume matrix probe.The original data was recorded and was analyzed by using off-line 3DT analysis software (TomTec 4D MV-Assessment).The longitudinal peak systolic strain and 16 segment systolic strains and strain mean value in 16 segment of left ventricular were acquired and compared.Results The peak strain of apical segment was lower than that of the basal segment and the middle segment and it had an increasing trend from the apical segment to the basal segment in three uremia groups.Instead,it had a decreasing trend from the apical segment to the basal segment in control group.But the differences were not statistically significant.The longitudinal peak systolic strain value,16 segment strain value and mean value of 16 segment strain all were lower in three uremic groups than those of control group.Every segment of 16 segment stain value in group A was higher than those of group B and C.There was no difference in every segment between B and C group in addition to basal and middle segment of anterior septum.Conclusions 3D-STE could evaluate the left ventricular systolic function in uremic patients and the cardiac function could be partly protected by regular dialysis treatment.

Objective: To analysis the relationship between glucocorticosteroids (GCS) usage and side effects in the treatment of severe acute respiratory syndrome (SARS). Methods: All clinical records of probable SARS patients in Beijing were collected and input into an Epi6 database, in which 1 291 patients had entire information and met the clinical criteria of SARS. The usage of GCS and GCS associated side effects were analyzed retrospectively. Results: Patients accepted GCS therapy were 83.96% (n= 1 084), whereas 16.04%(n=207) did not take GCS. The average dosage of GCS was 160 mg/d in the first week, and then reduced to 80 mg/d and 40 mg/d in the second and the third weeks, respectively. Initial blood glucose, systolic pressure (SBP), and diastolic pressure (DBP) were no significant difference between GCS group and non-GCS group. The highest blood glucose during the treatment in GCS group was markedly higher than that in non-GCS group [(8.68? 4.80 ) mmol/L vs (6.39?3.71) mmol/L, P05). After GCS administration, SBP and DBP were increased gradually, and reached their peaks in the fourth week [SBP (117.2?14.0) mm Hg and DBP (72.5?9.1) mm Hg vs SBP (120.0?12.5) mm Hg and DBP (74.5?8.7) mm Hg, P
