Objective To compare the performance of fourth generation HIV antigen/antibody combined detection reagents for HIV early infection samples,international HIV seroconversion panel samples and routine clinical screening samples.Methods Thirty seven early HIV infected samples from the followup gays in Shen Yang between 2009 and 2011,66 seroconversion panel samples from BBI company (U.S.A),NABI company(U.S.A) and NIBSC company(U.K) and 703 routine HIV screening samples in the first hospital of China medical university in October 2010 were collected.All kinds of samples were tested by three diagnostic reagents based on chemiluminescence assay (CLIA),electrochemiluminescence assay (ECLIA) and enzyme-linked immunosorbent assay (ELISA) respectively.The detection sensitivity and specificity of these assays were analyzed.Results For 59 early infected and seroconversion samples,the sensitivities of both ECLIA and CLIA reagent were 96.61％ (95％ CI 91.5％-100.0％),higher than that of the ELISA kit (95％ CI 75.0％-92.9％) (x2 =5.341,P ＜ 0.05),which is 83.93％ ; Comparison among the three reagents for different subtypes of the antibody seroconversion samples showed that ECLIA had the highest sensitivity while CLIA was the lowest ; Detection sensitivity of the three reagents for the P24 antigen is CLIA ＞ ECLIA ＞ ELISA; With detection of 703 clinical routine screening samples,the specificities of three reagents were 100％ (CLIA),99.86％ (ECLIA) and 99.71％ (ELISA) respectively.Conclusions For the sensitivity of the fourth HIV diagnostic reagents CLIA and ECLIA are better than ELISA.The former two reagents are more suitable for identifying earlier HIV infection in clinic.

Objective:To observe the effect of the proteininhibitor of activated STAT 3 (PIAS3) on the proliferation and apopto-sis of U251 glioma cells after PIAS3 expression was inhibited by RNAi. Methods: Three RNAi expression vectorstargeting PIAS3 were constructed and transfected into CHG-5 cells by liposomein vitro. The most efficient RNAi vector was subsequently selected by examiningthe mRNA expressions of PIAS3 in the transfected cells by semi-quantitativeRT-PCR. The selected RNAi vector was then transfected into U251 cells. After 48h of transfection, the mRNA and protein expressions of PIAS3 in glioma cellswere examined by semi-quantitative RT-PCR and western blot. Apoptosis wasobserved by flow cytometry using a double-staining method with FITC-con-jugatedannexin V and PI. Flow cytometry was also applied in cell cycle assay. Results:RNAidownregulated the mRNA (P<0.01) and protein (P<0.01) expressionsof PIAS3 in transfected cells.RNAi promoted the resistance of U251 cells to apoptosisand subsequently al-tered the cell cycle. A high percentage of G2 phaseand a low percentage of Sphase were observed in U251 cells. Conclusion:The down-regulation of PIAS3arrested U251 cells in the G2 phase andinduced the resistance of U251 cells to apoptosis.

Objective To detect content of 4-hydroxy-3-methoxy benzoic acid by RP-HPLC and observe the inhibitory effect of phloroglucinol on catecholamine-O-methyl transferase (COMT). Methods This study used the principle of 3,4-dihydroxy benzoic acid transforming to 4-hydroxy-3-methoxy benzoic acid under COMT’ s catalytic action. COMT (20 μL) was extracted from mouse liver homogenate. In a reaction system,10 μL catecol (1í10-3 mol·L-1 ) and 10 μL phloroglucinol (5í10-3 , 1í10-3 and 2í10-4 mol·L-1 ,respectively) were added. Products were determined by RP-HPLC to analyze effects of 4-hydroxy-3-methoxy benzoic acid on COMT. Results Phloroglucinol had inhibitory effect on COMT activity at concentrations of 5í10-3 mol·L-1 ,1í10-3 mol·L-1 and 2 í10-4 mol ·L-1 ,with the inhibition rate being 25. 3% ,17. 6% and 8. 9% ,respectively. Conclusion Phloroglucinol has an inhibitory effect on COMT activity,which is weaker than the effect of catechol of the same concentration.

BACKGROUND:Pancreatic stelate cels transforming growth factor β1/Smads signaling pathway activation is probably a main molecular mechanism of pancreatic fibrosis. If this pathway can be blocked, the progression of fibrosis of tissues with chronic pancreatitis wil be inhibited. OBJECTIVE:To study the inhibitory effect of colchicine on transforming growth factor β1/Smads pathway in chronic pancreatitis rat models. METHODS:Healthy male Sprague-Dawley rats were randomly divided into colchicines-treated group and chronic pancreatitis group. After successful establishment of rat models of chronic pancreatitis, the rats in the colchicines-treated group were intraperitonealy injected with colchicine 150 μg/kg daily. The rats in the chronic pancreatitis group were intraperitonealy injected with equal volume of physiological saline daily. Pancreatic tissues were colected after 3 months. Hematoxylin-eosin staining was used to observe histopathological changes of pancreatic tissue. Immunohistochemical staining was used to detect the expressions of transforming growth factor β1 in pancreatic tissue. Western blot assay was utilized to detect the expressions of P-Smad2, P-Smad3 and α-SMA protein in pancreatic stelate cels. RESULTS AND CONCLUSION: Hematoxylin-eosin staining results revealed that compared with the colchicines-treated group, glandular tissue had reduced, while fibrous connective tissue and inflammatory cels had increased obviously and replaced the pancreatic gland tissue in the chronic pancreatitis group. Immunohistochemical staining results demonstrated that the expression levels of transforming growth factor β1 and the index of positive cels were significantly lower in the colchicines-treated group than those in the chronic pancreatitis group (P < 0.05). Western blot assay results revealed that the results of P-Smad2/β-actin, P-Smad3/β-actin andα-SMA/β-actin in pancreatic stelate cels were significantly lower in the chronic pancreatitis group than those in the colchicines-treated group (P < 0.05). Results suggested that colchicine could inhibit the activity of transforming growth factor β1/Smads pathway and pancreatic tissue fibrosis in chronic pancreatitis rats. Therefore, colchicine can be used as a new candidate therapeutic scheme for chronic pancreatitis fibrosis.
