International Journal of Laboratory Medicine 2006;0(03):-
Objective To establish an ELISA method for detection of the concentration of TAP in human urine samples.Methods TAP-BSA was used as coating antigen. The TAP was a competitor to TAP-BSA. They reacted to the limited amount of monoclonal antibody against TAP.Results The optimal concentration of the coating antigen was 250ng/ml.The dilutions of monolclonal antibody against TAP and sheep anti-mouse IgG were 25?g/ml and 1∶4 000 respectively. The optimal range was from 0.69 to 1 000ng/ml.The assay provided a sensitivity of 0.69ng/ml.The coefficients of variation of intra-assay and inter-assay were 9.10% and 10.33% respectively. The average recovery rate of TAP was 97.70%.Conclusion The indirect competitive enzyme-linked immunosorbent assay is established.

Objective To investigate the effects of demethylating agent 5-Aza-2'-deoxycytidine (5-Aza-CdR) on the biological behaviors and the expression of RASSF1A of lung carcinoma cells H460. Methods Lung carcinoma cell line H460 were treated with 5-Aza-CdR. Cell proliferation was determined by MTT assay and colony forming test. The methylation status of RASSF1A gene was detected by PCR. The expression of RASSF1A protein was measured by Western blotting, and the cell cycle was analyzed by flow cytometry. Results With 5-Aza-CdR treatment, the proliferation speed of H460 lung carcinoma cells was slowed down and the colony formation rate of H460 cells was decreased significantly compared with control group (38.5 %, 27.5 % and 60.5 % in 5-Aza-CdR 5 and 10 μmol/L groups and control group, respectively, P <0.05). The methylation degree in the promoter of RASSF1A gene was decreased and the expression of RASSF1A protein was detected after 5-Aza-CdR treatment. 5-Aza-CdR induced G1 phase arrest of the H460 cells. Conclusion The hypermethylation of CpG island in the promoter of RASSF1A gene results in the loss of RASSF1A protein expression in human Lung carcinoma cell line. The demethylating agent 5-Aza-CdR could restore RASSF1A gene expression.These findings provide theoretic evidence for clinical treatment of human lung carcinoma with demethylation agent 5-Aza-CdR.

The effects of positive end-expiratory pressure (PEEP) on pulmonary shunt were studied during gen- eral anesthesia and postoperative period.Twenty cholecystectomy patients were randomly divided into experiment group (group P) and control group (group Z). PEEP and ZEEP were used separately after induction. Artery blood and mixed blood from the right ventricle were taken for blood gas analysis and determine the amount of pulmonary shunting before anesthesia. half and hour, one and half an hour and two and half an hour after anesthesia and one hour after the operation.The results showed that shunt in group P decreased gradually during general anesthesia and returned to the level of preoperation at an hour after operation. Shunt in group Z was increased continually and the level was significantly higher than preoperation an hour after operation. Shunt between two groups was significant difference (P

Objective To investigate the effect of EST on function of sphincter of Oddi and on the long-term complications.Methods A total of 68 patients with common bile duct stones were recruited from January 2009 to January 2013 in The First People's Hospital of Hangzhou.All patients were under follow-up to observe the incidence of late complications after EST.Oddi sphincter manometry and bile bacterial culture were performed before EST and one year later.Results With the 13-36 months follow-up,the incidence of late complications was 16.9% (11/65).The peak pressure and frequency of contraction of Oddi sphincter after EST were significantly lower than those before EST,but there were no significant differences between patients with complication and without (P > 0.05).After EST,positive rate of biliary bacteria in patients with complications was much higher than that in patients without complications [70% (7/10)vs.31.7% (13/41),P =0.026],although there were no significant differences between them before EST [54.5%(6/11) vs.46.3% (25/54),P =0.618).Logistic regression analysis showed that cholecystolithiasis,bile duct diameter (> 1.5 cm),number of stone (> 3),maximun diameter of stone (> 20 mm),large EST were independent risk factors for late complications of EST.Conclusion Importance should be attached to the late complications of EST with Oddi sphincter function declination,and biliary enteric reflux being the basic factor in late compilations after EST,which are also influenced by many risk factors.

Objective:To evaluate the application value of diffusion tensor imaging (DTI) in guiding the postoperative radiothera-py plan of the gliomas adjacent to the corticospinal tract (CST). Methods:Thirty patients with gliomas adjacent to the CST underwent routine magnetic resonance imaging (MRI) contrast-enhanced scanning and DTI after radiotherapy. Tractography data sets were ac-quired and were fused with the images of corresponding anatomical MRI and computed tomography. The acquired data sets of radio-therapy planning system were imported to assist with the delineation of the target volume, organs at risk, and CST. Two sets of radio-therapy plan, which considered or did not consider the dose protective effect of the CST, were formulated and compared using the treat-ment technique of intensity modulated radiotherapy. Results:The protective radiotherapy and unprotected plans both achieved the thera-peutic dose to the target volume and the protection of the routine organs at risk. In the protective dose (with an optimization program that considered the dose reduction of CST), the maximum and mean radiation doses suffered by the patients' ipsilateral and contra-later-al CSTs were lower compared with the unprotected plan (P<0.05). Conclusion:DTI can identify the location and shape of CSTs, and their relationship with the postoperative radiotherapy target of gliomas. These findings contribute to the formulation of a protective ra-diotherapeutic regimen to keep the CST from the maximum and the mean radiation doses to the largest extent, thereby decreasing the possibility of nerve damage after radiotherapy.

Objective: To investigate the effects of Rehannia glutinosa decoction (RGD)、 Rehmannia glutinosa polysaccharide (RGP) and Rehmannia glutinosa non polysaccharide (RGNP) on peripheral hemogram in mice. Methods: The first experimental group were continuously given RGD、RGP and RGNP for nine days, and then blood sample was taken from tails for determination of peripheral hemogram. The second group were given RGD、RGP and RGNP for five days, after making the blood difficiency model of cyclophosphamide. Determinating peripheral hemogram of the third group, after that those mice were given cyclophosphamide by 2 days, 4 days, 6 days, 8 days. Results: Peripheral hemogram of the every normal group has no difference. To compare the model of blood difficiency group and the control group, there were significant differences, RGNP can only enhance WBC. Both RGP and RGNP can reduce WBC of the mice model of anti cyclophosphamide, while RGP was superior to RGNP. Conclusion: Rehmannia glutinosa has dual directional adjustment function. RGP is tonifying blood active fraction of RG.
