We established a new method, the E-ELISA, to detect red-cell immune adherence (RCIA) activity and the value of immune complexes on the surface of red cell. This method has a good specificity, reproducibility and easily perform, with a sensitivity of 31.25ng/100ul. Fifty samples from normal human were determined. The RCIA activity was 5445 (3.73 ? 0.22 LgG,ngAHG/10~7RBC and the value of immune complexes on the surface of red cell was 234.7(2.37 + 0.21LgG)ngAHG/10~7RB C. We likely suggest that this method is a good tool for study of immune fanction of erythrocytes

BACKGROUND:Three-dimensional visual model of cervical deep vein can be used to virtual simulation of puncture. The studies on elevating deep vein puncture in the clinic are stil in the stage of exploration.
OBJECTIVE:To find the application of three-dimensional virtual puncturation simulation to cervical deep vein puncturation.
METHODS:CT cross-sectional images were obtained from healthy volunteers. Mimics software was used to semi-automatical y cut and reconstruct of various tissue of the neck. Three-dimensional model revealed cervical deep veins and its surrounding anatomic structure. Cervical deep vein puncturation was simulated, including internal jugular vein, supraclavicular vein and subclavian vein.
RESULTS AND CONCLUSION:Three kinds of cervical deep vein puncturation were successful y simulated, showing three-dimensional adjacent relation of the virtual pin with surrounding anatomic structure. Safe angle, depth and optimal path of the pin were measured. A three-dimensional virtual puncturation simulation can provide visualized morphologic data for cervical deep vein puncturation.

Objective To investigate the different effects of clozapine and risperidone on levels of blood glucose in patients with schizophrenia. Method 200 qualified cases selected from psychiatric department were divided into two groups randomly, of which 100 cases accepted the treatment with clozapine and the other 100 cases with risperidone. Blood glucose tests were used before treatment ,4 weeks after treatment and 8 weeks after treatment Results There was significantly higher blood glucose level in clozapine－ treated group than in risperidone－ treated group after 4 or 8 weeks treatment. The number of cases who had elevated blood glucose level (>6.1 mmol/L) in clozapine－ treated group was significantly more than in risperidone－ treated group. Conclusion The glucoregulatory abnormality which leads to glucose elevation in clozapine－ treated patients is greater than in risperidone－ treated patients. Additional motivation to clinical monitor for antipsychotic treatment－ related hyperglycemia is indicated.

BACKGROUND:With the rapid development and wide application of proteomics techniques,effective tools are available for exploring specific biomarkers for early detection and diagnosis of liver diseases.Recent years,many novel and promising biomarkers have been discovered and evaluated.OBJECTIVE:To review the advances and applications of proteomics in liver development,regeneration and diseases.RETRIEVAL STRATEGY:A computer-based online search of Medline database was undertaken for the English literatures about liver diseases and proteomics published from January 1995 to July 2007 with the keywords "proteomics,liver".Meanwhile,Chinese articles published from January 1995 to July 2007 were searched in CNKI database,with the same keywords in Chinese.The retrieved articles were screened firstly,and those about proteomics and liver diseases were selected and searched for full texts.Repetitive studies and Meta analysis were excluded.156 articles about the proteomics and liver diseases were collected,and finally 32 articles were included.LITERATURE EVALUATION:Of the 32 articles,3 were about the research background of proteomics,6 about proteomics under healthy status,and 23 about proteomics research in liver diseases.DATA SYNTHESIS:Proteomics is a novel science to study protecome using various techniques.The study of the proteome,called proteomics,now evokes all the proteins coded by gene in any given organism,tissue,cell,and even organelle.The researches of proteomics help us to find and understand the life as a whole.Nowadays,there lacks of effective strategy in diagnosis,stages,and treatment in liver diseases.Proteomics is promising in alertness,diagnosis,treatment and prognosis in liver diseases.CONCLUSION:With the deepened study of proteomics in liver diseases,there will be a revolution in the diagnosis and treatment of liver diseases.

Objective To evaluate the cerebrovascular reserve(CVR) in patients of ischemic stroke with cerebrovascular stenosis by Xenon-enhanced CT. Methods Twenty subjects of ischemic stroke with cerebrovascular stenosis were recruited. All subjects were examined by Xenon-enhanced CT before and after acetazolamide (ACZ) challenge test to quantitatively measure the regional cerebral blood flow (rCBF) and CVR. Results We compared the rCBF in the corresponding region supplied with stenosed artery (divided manually) with that in the region of normal side. There was no significant difference in resting rCBF but in CVR [ipsilateral side vs. normal side ( 5.9 ± 24. 3 ) % vs ( 25.9 ± 32. 6 ) % , P ＜ 0. 05]. Conclusion Impaired CVR is an important character of the patients with cerebrovascular stenosis suffered from ischemic stroke.

ObjectiveTo explore the clinical effectiveness of intralesional glucocorticoid therapy on infantile hemangioma in proliferative stage,and variance of vascular endothelial growth factor(VEGF) expression in the hemangioma tissues.MethodsExperimental group:5 cases were injected with triamcinolone acetonide 3 days before operation,5 cases were done 6 days before operation,5 cases were done 9 days before operation and 5 cases were done 2 weeks before operation(the dose of injection was 1 mg/cm2 per time,but not exceeding 2 mg/kg).Control group:5 infantile hemangioma cases in involuting stage and 5 infantile hemangioma cases in proliferative stage did not received any therapy.The specimen of the hemangioma were collected to detect the expression of VEGF by two-step immunohistochemistry.Every optical slice was detected by 5 campus visualis of high power lens.ResultsObserving the specimen dyed by HE in the light microscope,there was no significant difference between injected group and non-injected group.But by means of immunohistochemistry,the expression of VEGF could been down regulation by the glucocorticoid(F=17.919 1P

[Objective]To explore the cause of the early complications of Bryan cervical disc arthroplasty and summarize the prevention experience. [Methods]From June 2006 to December 2007,60 patients(33 males and27 females) with 73 levels underwent Bryan cervical disc placement.The average age was 43.3 years(range,33-54 years).[Results]One case complained of persistent arm pain because of incomplete decompression and was treated by dehydration,but the pain was still present.The average period of follow-up was 15.6 months,JOA scores were improved from 8.34?1.22 points to 16.11?1.01 points(P

Purpose:To evaluate the protection of astragalus injection for Doxorubicin (adriamycin)-associated cardiotoxicity. Methods:58 patients were randomized into two groups for this clinical trial. 30 patients were in the test group ,and 28 in control group. Patients in the test group received astragalus injection in 5% glucose solution once every day for two weeks starting three days before adriamycin-based chemotherapy. 28 patients in the control group began to receive oral vitamin E 100 mg twice a day and coenzyme Q10 20 mg three times a day for two weeks. Chemotherapy is the same as that in the test group. Electrocardiogram (ECG) and echocardiogram were employed to evaluate the cardiac function. Results:There was a substantial difference in ejection fracton between the two groups,but the difference was not statistically significant. Statistically significant differences were observed in the two groups with regard to all other parameters,including abnormal changes in ECG and LVIDD、LVISD、A/E、FS. Conclusions:Astragalus injection is a good drug which can prevent the occurrence of acute cardiotoxicity associated with adriamycin. It can also reduce the occurrence of chronic cardiotoxicity.
