OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.

BACKGROUNDThis study evaluated the feasibility, efficacy and safety of CT-guided percutaneous radiofrequency ablation in patients with spinal osteoid osteoma.

METHODSTwo patients suffered spinal osteoid osteoma were treated with CT-guided percutaneous radiofrequency ablation under local anesthesia. Lesions located in sacral vertebrae and cervical vertebrae, which were adjacent to nerve root and spinal canal respectively. Tumors were treated under 90°C radiofrequency temperature lasting 4 minutes by an electrode placement. Visual analog scale was used to evaluate the pain improvement.

RESULTSNo complications were observed pre- and post-operation. Patients recovered to normal activities immediately and achieved complete pain relief in 24 hours. No symptoms were recurrent in 5 months and 4 months follow up. Mild scoliosis has been recovered in case 2.

CONCLUSIONSCT-guided percutaneous radiofrequency ablation of spinal osteoid osteoma is safe, effective and has more clinical benefits. The long-term outcome needs further observation.

OBJECTIVETo practice a more atraumatic, physiological and aesthetically valued approach of construction for neovagina.

METHODSLaparoscopically using peritoneum as neovagina lining.

RESULTSFrom March 2005 to September 2006, this technique was adopted to treat 10 patients whose diagnosis was congenital absence of vagina. The ages of the patients were from 19 to 32. The operation lasted average 2.34 hours. And hospitalization was about 20.5 days. Follow-up ranged from 3 - 12 months. No complication occurred. All of the patients was satisfied with their sexual life.

CONCLUSIONSLaparoscopically assisted neovaginaplasty, in which peritoneum was substituted for vaginal mucous membrane, was a kind of ideal approach of vaginal creation.

OBJECTIVETo assess the preventive effect of sodium valproate on early posttraumatic seizures in traumatic brain injury (TBI) patients.

METHODSThe retrospective study was based on 159 patients with TBI treated at Department of Neurosurgery, Nanjing General Hospital of Nanjing Command enrolled between January 1, 2008 and December 31, 2009. The in-hospital section of the retrospectively collected database includes information on age, sex, initial Glasgow Coma Score (GCS), results of CT scanning, operation, usage of sodium valproate, seizures in the first week after injury and outcome.

RESULTSSeven patients (4.4%) showed early posttraumatic seizures. Although the incidence was zero in patients who received sodium valproate treatment, the difference between the treatment and control groups was not statistically significant. Of the 87 severe TBI patients (GCS 3-8), 6 patients in the control group (6.9%) suffered from early seizures during the first week after TBI and no patient who received preventive therapy suffered from seizures. The difference between the treatment and the control groups was still not statistically significant. Of the 72 mild and moderate TBI patients (GCS 9-15), only 1 patient in the control group suffered from seizures and no patient in the treatment group suffered.

CONCLUSIONSAlthough the results suggest that the study is not sufficiently powerful to detect a clinically important difference in the seizure rates between the treatment and control groups, sodium valproate is effective in decreasing the risk of early posttraumatic seizures in severe TBI patients. Further prospective studies are recommended.

Objective To measure the maximum dissolved oxygen concentration of the lithotripter to avoid visible air bubbles during lithotripsy.Methods The present situation of degassing of lithotripter and clinical requirements for water were introduced.Under the following conditions of 7.5 L water capacity,35 L/h water flow,ambient temperature 28 ℃,17 kV,60 shocks per minute,the lithotripter discharged 10 000 shocks continuously without a visible air bubble in the circulating water,then the dissolved oxygens in the water were measured by using AZ8403 dissolved oxygen meter.The maximum value of dissolved oxygen in the water was determined therefore without a visible air bubble.Results The visible tiny air bubble emerged during lithotripsy if the dissolved oxygen in the water was above 3.37 mg/L and ambient temperature was about 28 ℃;the bubble could be avoided if the dissolved oxygen was under 3.34 mg/L and ambient temperature was about 28 ℃.Conclusion The circulating water with dissolved oxygen concentration less [han 3 mig/L and about 28 ℃ ambient temnperature are recommended for the electromagnetic extracorporea] shock wave lithotripter during lithotripsy.

Objective To investigate the clinical significance of a new method,axis-line-distance technique(ALDT),in scoliosis measurement.Methods Thirty cases with idiopathic scoliosis were measured on two separate occasions by six observers with the Cobb technique and the ALDT on PACS workstation.The interval time between two measurement occasions were three weeks.The data were analyzed statistically with the paired-sample t-test.Results(1)Concerning intraobserver variance in two measurement occasions,the minimum variance,the maximum variance and the average variance were 0, 24.00?,5.71??1.54?for Cobb technique and 0,12.00 mm,(1.95?0.58)mm for ALDT.There were significant measurement differences for four observers with Cobb method 39.00??10.69?versus 36.50?? 10.63?,31.73??10.96?versus 37.30??9.65?,32.03??7.49?versus 27.86??9.00?,29.77??8.87? versus 34.20??7.26?,all P0.05].(2)Concerning interobserver variances in six observers,the average measurement variance was 5.07??0.35?for Cobb method,and(2.32?0.26)mm for ALDT.
