Objective To compare the efficacy of ultrasound -guided percutaneous catheter drainage and incision and drainage catheter in treatment of liver abscess.Methods 50 cases with liver abscess who had given ultrasound -guided percutaneous catheter drainage as the observation group were randomly selected and 50 cases with liver abscess who had given open catheter drainage over the same period were selected as the control group.The cure rate,white blood cell count(WBC),body temperature returned to normal,extubation time,hospitalization and the occurrence of complications of two groups were compared.Results (1)The WBC,body temperature returned to nor-mal,extubation time,hospitalization of the observation group were (4.35 ±1.45 )d,(3.68 ±1.68)d,(10.85 ± 1.66)d,(13.76 ±2.80)d,which were significantly shorter than (7.66 ±2.83)d,(6.22 ±2.75 )d,(13.05 ± 1.95)d,(17.96 ±2.91 )d of the control group.The difference between the two groups had statistically significant (t1 =8.352,t2 =9.145,t3 =7.552,t4 =8.443,all P <0.05);(2)One case of postoperative wound infection of the observation group,the complication rate was 2%,two cases of postoperative wound infection of the control group,one case of empyema,two cases of bleeding,the incidence was 10%,the difference in the incidence of complications between the two groups were statistically significant(χ2 =6.73,P <0.05).Conclusion Ultrasound -guided percu-taneous catheter drainage was trauma,quick recovery,safer,which is worthy of clinical application.

Objective To evaluate the clinical value of high-frequency color doppler ultrasound in diagnosis of common carotid artery vasculopathy of diabetes mellitus. Methods High-frequency color doppler ultrasound was used to detect the intima-media thickness (IMT), inner diameter(CCAD), resistent index (RI) and atherosclerotic plaque of common carotid artery in 40 patients with diabetes, and then compared with 35 normal cases. Results IMT,CCAD and RI as well as incidence of atherosclerotic plaque of common carotid artery in diabetics were signifi-cantly higher than that in the control group(P < 0.05). Conclusion High-frequency color doppler ultrasound can di-rectly show the degree of carotid lesion and atherosclerotic plaque, and is of practical value and a guide in diagnosing atherosclerosis and preventing brain embolism in diabetics.

Objective To investigate the effect and mechanism of ganoderma acid in therapy of the rat essential hypertension.Methods 30 male spontaneously hypertensive rat (SHR) were divided randomly into three groups:control group (CG),ganoderma acid group (Gan) and captoril (Cap) as positive control group.SHR were fed with distilled water (10 ml/kg) in control group,ganoderma acid (0.6 g/kg ) in Gan group,catopril (0.03 g/kg) in Cap group.After 8-weeks therapy,5 ml blood was extracted,rats in every group were sacrificed to get the aorta.The mRNA expression of superoxide dismutase (SOD),nitric oxide synthase (NOS) and high density lipoprotein (HDL) were detected by RT-PCR and the apoptosis of endothelial cells were measured by flowcytometry.Results After the 8 weeks therapy,as compared with the CG group,blood pressure of SHR in Gan group became stable[(112.6±3.2) mm Hg](P＜0.01).The expression of SOD,NOS and HDL showed obviously upregulated,and apoptosis of endothelial cell decreased significantly (P＜0.01).NO contents increased,and MDA,ET-1 decreased (P＜0.01).The contents of LDL decreased and HDL increased (P＜0.01).Conclusions Ganoderma acid may improve the function of endothelial cell and decrease the blood pressure by promoting the mRNA expression and activity of SOD,cleaning the radical ions and inhibiting the apoptosis of the endothelial cell.

Objective To discuss the relationship of metabolizing enzyme Cystathionine βsynthase (CBS) G919A gene polymorphism with essential hypertension on Hui nationality in Xinjiang. Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the gene polymorphism, blood lipid, blood sugar and other biochemical indicators were tested at the same time. Result The distribution frequency of genotype GG, GA, AA and A,G, of CBS G919A was 76.4%, 19.0%, 4.5%, which was of no significant difference compared with the control group (P > 0.05). Conclusion Gene polymorphism of CBS G919A was existed, which was no relationship with essential hypertension on Hui nationality in Xinjiang.

ObjectiveTo investigate the characteristics of three vaginal bacteria inspection methods of Amsel method,gram staining Nugent score method and bacterial vaginosis (BV) Blue methodMethods The leucorrhea specimen of 99 vaginal fluid abnormal patients were examined by Amsel method,gram staining Nugent score method and BV Blue method,then compared and analyzedResultsThe positive rate was 28.28％ (28/99) in Amsel method,47.47％(47/99) in gram staining Nugent score method and 16.16％ (16/99) in BV Blue method.There were significant differences among three methods(P＜ 0.01 ).The specificity and sensitivity of gram staining Nugent score method was higher.ConclusionThe three vaginal bacteria inspection methods have advantage and shortcoming individually,suspecting patients should be followed up to detect and diagnose in chnic,or detected by many methods.The specificity and sensitivity of gram staining Nugent score method is higher,but BV Blue method is simple,faster,which has higher value in detection and diagnosis in BV.

Objective To compare the performance of two commercially available ELISA kits for detection of diphtheria IgG antibody to provide data for the proper kit choice. Methods Thirty-three serum samples from staff of the capital airdrome and two standard sera were tested for the evaluation of the kits.Commercial ELISAs were compared with respect to their reproducibility(intra-assay variation and inter-assay variation)and accuracy.Results For the detection of standard serum,intra-assay variation(Coefficient of Variation,CV)was 13.5507% for IBL kit and 5.9541% for Virion kit,the inter-assay variation(CV)was 9.9890% for IBL and 2.4728% for Virion kit.For the serum sample,intra-assay variation(CV)was 14.5270% for IBL and 11.0612% for Virion,the inter-assay variation(CV)11.0039% for IBL and 8.1506% for Virion kit.For the detection of standard serum,inter-assay variation(CV)was 9.9890% for IBL and 2.4728% for Virion.The accuracy was analyzed by variation between the actual concentration and measured concentration of standard serum,the CV was 17.6889% for IBL and 1.3966% for Virion.Conclusion The intra-assay and inter-assay variation of the two kits are generally acceptable(CV

Military medicine has to restructure itself to meet military needs and e-Science patterns of the information age.This restructuration is known asinformationization of military medicine ( IMM).IMM is a process of vision refresh-ing into information thinking, mission expansion to the information field and paradigm shift to normal forms of information. The result is the emergence of military med-information technologies, military med-information research fields, and military med-informatics disciplines.

Objective To explore the clinical effect of the percutaneous vertebroplasty(PVP) and filling auto-solidification calcium phosphate cement(CPC) in treatment of osteoporotic thoracolumbar vertebral fractures. Methods From January, 2004, 26 patients with osteoporotic thoracolumbar vertebral compression fracture (29 vertebral bodies) were treated with intraoperative manipulative reduction, PVP and filling auto-solidification CPC. Results PVP were successfully performed with unilateral or bilateral vertebral pedicles for the 29 vertebrae. The average injection dose of CPC was 4.6 mL. CPC leakage occurred during the procedure in 5 vertebrae of 5 cases. All the patients were followed up for 3 to 8 months (averaging 4.6 months) and experienced complete pain relief. There was no severe complication related to the treatment. Except in 3 patients who lost 15%of the vertebral body height, the anterior height of the injured vertebral body in the other 23 patients recovered averagely to 80%of the normal one. Conclusion PVP with filling auto-solidification CPC is safe and effective in the treatment of osteoporotic thoracolumbar vertebral compression fractures.
