Objective To investigate the effect of endovascular brachytherapy with Rhenium-188-filled catheter balloon on cell proliferation,phenotype of smooth muscle cell and secretion of transforming growth factor; to explore the possible mechanism of this method employed in restenosis prevention. Methods After the right common carotid arteries were overstretched by 3.5?20 mm balloon,twenty New Zealand White rabbits were randomized into irradiation (n=10) and control group (n=10). Endovascular bachytherapy was performed wth a 188[KG*2/2]Re filled 3.0?20 mm balloon catheter delivering a dosage of 16 Gy (0.5 mm underneath the luminal surface) in the irradiation group, whereas isovolume normal-sodium-filled balloon catheter was used in the control group for an equal period. After thirty days, analysis of the carotial arteries was made by measns of histological and immunohistochemical staining. Results (1) The positive staining index of proliferation cellular nuclear antigen (PCNA) and transforming growth factor (TGF) of the irradiation group is significantly less than the control group (0.028?0.005 vs 0.054?0.011, 0.033?0.008 vs 0.063?0.014, respectively); (2) The positive staining of ?-actin index in intima has no significant difference between the irradiatin group and the control group. Conclusion (1) The preventive effect on restenosis with endovascular brachytherapy is possibly achieved by suppression of cellular proliferation and transforming growth factor secretion. (2)The phenotype of smooth muscle cell is possibly unaffected by endovascular brachytherapy.

One hundred and two pregnant women with obstructive sleep apnea hypopnea syndrome (OSAHS) and 36 healthy pregnant women( control group)were enrolled in the study.Serum visfatin and macrophage migration inhibitory factor (MIF) levels were detected by enzyme linked immunosorbent assay (ELISA).The results showed that apnea-hypopnea index (AHI),mean arterial pressure(MAP),serum visfatin and MIF levels in pregnant women with OSAHS were significantly higher than those of controls ( all P＜ 0.01 ). In pregnant women,AHI,serum visfatin and MIF levels of patients having OSAHS with hypertension were significantly higher than those of patients with OSAHS only (all P ＜ 0.01 ).Patients with severe OSAHS had higher levels of visfatin and MIF than those with moderate OSAHS,and patients with moderate OSAHS had higher visfatin and MIF levels than those with mild OSAHS ( P ＜0.01 ).The AHI was significantly correlated with MAP,serum levels of MIF and visfatin ( r =0.75,0.71,0.68,respectively,all P ＜0.01 ) in pregnant women with OSAHS.

Objective To analyze the influence of Wiltse approach and conventional transmuscular approach on the mul?tifidus muscle by imageology, histology and electrophysiology assessment following short?segment pedicle fixation on thoracolum?bar fractures. Methods 76 patients with thoracolumbar fractures without neurological deficits who had undergone short?segment pedicle fixation between June 2010 and August 2012. Wiltse approach 36 cases, conventional transmuscular approach 40 cases. The perioperative parameters, Visual Analogue Scale scores (VAS), and radiologic parameters, esp the imageology, histology and electrophysiology changes of multifidus muscle were compared. Results 20 cases were fellowed up over 1 year in the Wiltse ap?proach group (20/36, 56%). 25 cases were fellowed up over 1 year in the conventional transmuscular approach group (25/40, 62.5%). No significant differences were found in terms of gender, age, fracture type, injured segment and follow?up period. Till the last follow?up, all patients with vertebral fractures were healed. No loosening or breaking of internal fixation was observed. Com?pared to the conventional transmuscular approach, the Wiltse approach was significantly advantageous in terms of operation time, the amount of bleeding, hospital stays and VAS scores after the surgery but the length of incision, besides, the Wiltse approach group had less incidence of multifidus atrophy and less fatty infiltration, and in conventional transmuscular approach group electro?myography demonstrated that the multifidus muscles median frequency values and average amplitude value were significantly low?er than Wiltse approach group. Conclusion The Wiltse approach for thoracolumbar fractures, retaining the posterior ligament complex, is an effective and minimally invasive treatment, with less trauma, less bleeding, less operation time, the advantages of re?liable clinical results. Especially less incidence of multifidus atrophy and less fatty infiltration.

Objective To examine the association between one-hour plasma glucose (1-hPG) level during an oral glucose tolerance test (OGTT) and serum lipid profiles in individuals with NGT. Methods 6 402 individuals with NGT who underwent a 75 g OGTT were screened from four communities of Hefei suburban areas, aged over 40 years. Then 1 291 cases of NGT were randomly selected as the object of this research by random data table method. They were divided into NGT-1 group (1-h PG < 8.6 mmol/L, n = 597)and NGT-2 group(1-h PG≥8.6 mmol/L, n = 694). Pearson correlation analysis and multivariate linear regression analyses were performed to assess correlations between 1-h PG levels and lipid profiles. Results (1) The average values of body mass index were 24.3 kg/m2 in NGT-1 group, and 24.5 kg/m2 in NGT-2 group. (2) Compared with individuals in NGT-1 group , fasting plasma glucose , two-hour plasma glucose during OGTT , HbA1c , triglyceride (TG), and high-density lipoprotein-cholesterol(HDL-c) levels, TG/HDL-c ratios, and total cholesterol(TCH)/HDL-c ratios were significantly higher in individuals than in NGT-2 group. By contranst, body mass index, blood pressure , TCH and low-density lipoprotein-cholesterol levels were not significantly different between NGT-1 group and NGT-2 group. (3) The multiple linear regression analyses showed that 1 h PG levels positively correlated with TG in individuals in both NGT-1 group and NGT-2 group (P < 0.01). In addition, 1-h PG levels negatively correlated with HDL-c ratio in both groups (P < 0.01). Conclusion 1-h PG levels during OGTT in overweight individuals with NGT closely correlate with HDL-c and TG levels.
