T-cell exhaustion is characterized by the stepwise and progressive loss of T cell functions under conditions of antigen-persistence, which occurs following chronic infections and tumor outgrowth. Exhausted T cells present functional defects, express multiple inhibitory receptors and show reprogrammed transcriptional regulation. As T cell exhaustion is correlated to its dysfunction to control infections and tumors, exploring new strategies to target exhausted T cell may reverse this dysfunctional state and reinvigorate immune response. This study takes CD8+ T cell as an example, which acts as an important subset involved in exhaustion state, discuss current understanding of the properties of exhausted T cell and the mechanisms that promote and maintain this state, and reveal new therapeutic targets for chronic infection and cancer.

Objective To study the renal damage of patients with juvenile primary Sjgren's syndrome (pSS)and its clinical manifestations,pathologic characteristics with biopsy,treatment and prognosis.Methods Ten patients with juvenile pSS complicated with renal impairments were retrospectively analyzed.Data of these 10 patients were compared with those without renal impairments.Results Ten patients complicated with renal impairments in 24 patients with juvenile pSS,9 of them presented with type I renal tubular acidosis(RTA), 5 with hypokalemia paralysis,3 with calcification of the renal tissue,3 with positive urine protein.1 with dia- betes insipidus.There was no significant difference between patients with renal impairments and those without. Three patients underwent kidney biopsy that showed chronic interstitial nephritis(CIN)with extensive lymp- hoplasmie cell infiltration.Two patients had glomerular lesions and one of them was diagnosed as pSS over- laped with systemic lupus erythematosus(SLE).Steroid and immunosuppressive agents had significantly alle- viated symptoms and the hypergammaglobulinemia was significantly improved.Conclusion Renal impairment may be the major complication in juvenile pSS.The major clinical manifestations are RTA and the glomeruli are involved occasionally.Treatment with steroid anti immunnsuppressive agents should be given to those who have evidence of systemic involvement.

OBJECTIVE: The optimal multiplicity of infection (MOI) of the recombinant adenovirus Ad-Rad50-GFP carrying a mutant Rad50 gene expression region on the cell growth of nasopharyngeal carcinoma and the viral amplification efficiency of CNE1 cell infected by this adenovirus were studied. METHOD: The biological titer of Ad-Rad50-GFP was measured by end point dilution method. The impact of recombinant adenoviral vector transfection on the growth of CNE1 cells was observed by cell growth curve. Transfection efficacy of recombinant adenoviral vector was observed and calculated through fluorescence microscope. The expression f mutant Rad50 in the Ad-Rad50-GFP transfected CNE1 cells with optimal MOI was detected by Western Blot after transfection. RESULT: The biological titer of Ad-Rad50-GFP was 1.26 x 10¹¹ pfu/ml. CNE1 cell growth was not influenced significantly as they were transfected by recombinant adenoviral vector with MOI less than 50. Transfection efficacy of recombinant adenoviral vector was most salient at 24 hours after transfection, with the high expression of mutant Rad50, and the efficiency still remained about 70% after 72 hours. CONCLUSION Recombinant adenoviral vector Ad-Rad50-GFP could transfect CNE1 cells as well as result in the expression of mutant Rad50 in CNE1 cells effectively. MOI = 50 was the optimal multiplicity of infection of CNE1 cells transfected by recombinant adenoviral vector Ad-Rad50-GFP.

OBJECTIVE:To study the effect of Shenkang injection on the irbesartan pharmacokinetics in rats in vivo. METH-ODS:18 SD rats were randomly divided into control group(normal saline)and Shenkang injection(calculated by crude drug as 4 g/kg),9 in each group,which were intraperitoneally injected twice a day,for 7 d. After 1 h of last administration,25 mg/kg irbe-sartan was intragastrically administrated. 0.3 mL sample blood was taken in fundus venous plexus before administration of irbesartan and after 0.25,0.5,1,2,4,8,12,24,32,48,56,72,96 h of administration. Using biphenyl diester as inner standard,HPLC was adopted to determine the plasma concentration of irbesartan in plasma of rats,and pharmacokinetic parameters were calculated by using non-compartmental model in Phoenix WinNolin? 6.1 pharmacokinetic software. RESULTS:After intragastrically adminis-trated irbesartan in rats in control group and Shenkang injection group,AUC0-96 h were (28.82 ± 10.49),(35.64 ± 9.99) mg·h/L;cmax were(0.64±0.15),(0.76±0.33)mg/L;tmax were(13.07±16.70),(10.23±3.97)h;CLZ/F were(0.85±0.35),(0.63±0.21) L/(h·kg);VZ/F were (38.24 ± 24.87),(30.99 ± 9.75) mL/kg respectively,with no statistical significances (P>0.05). CONCLU-SIONS:Shenkang injection will not affect the in vivo pharmacokinetics process of irbesartan in normal dose on rats.

Objective To study on the results of magnifying endoscopy in gastric atrophy, intestinal metaplasia (IM) and dysplasia, and evaluate their feasibility and accuracy for the diagnosis of these lesions. Methods One hundred patients were examined by magnifying endoscopy, Fujinon EG485 ZH modal, and stained with 0. 5% methylene blue. After defining magnifying endoscopic patterns of gastric pits as types A, B, C, D, and E, the diagnostic classification and endoscopic criteria were developed for the diagnosis of atrophy, IM and dysplasia. The results of 417 histopathological biopsy specimens taken from the corresponding areas of gastric mucosa under magnifying endoscopy were regarded as gold standard. Results Sparse and thick gastric pits mainly appeared in gastric atrophy, IM mainly appeared in gastric mucosa of type C, type D, and type E with positive stain, dysplasia appeared as depressed, slightly raised, or flat mucosa accompanied by loss of clear pattern, fine pits or coarse and irregular microstructure. The sensitivity and specificity of magnifying endoscopies in the diagnosis of atrophy, IM and dysphasia were 95. 85% , 95. 09% ; 88. 30% , 90.83% ; and 91.52% , 94. 41% respectively, all were higher than those of routine endoscopy. Conclusion The diagnostic accuracy significantly increased as depending upon the morphological features of gastric atrophy , IM, or dysplasia under magnifying endoscopy.

Objective To evaluate the feasibility and diagnostic accuracy of CE-MRA with low dose contrast agent by comparison with DSA in diabetic patients with peripheral arterial diseases. Methods ( 1 )Study in vitro: test tubes containing Gd-DTPA of different concentrations were scanned, and the relationship between signal intensities and concentrations of GD-DTPA was analyzed. DSA and CE-MRA with selected concentrations of Gd-DTPA were performed on stenotic vascular models to estimate the proper low dose of GD-DTPA for clinical applications. (2) Clinical applications: 78 diabetic patients with peripheral arterial diseases were scanned from the abdomen and pelvis station to the calf-foot station in a 3 T MR system with standard bolus chase 3D CE-MRA sequence after injection of 13 ml GD-DTPA . The image quality,diagnostic rate of stenosis of arteries in calf and degree of venous contamination were evaluated with Fisher's exact test. DSA images of 220 vascular segments in 22 patients ( 10 segments per patient) were acquired as the gold standard and compared with CE-MRA by using Kappa test. Results The MR signal intensities were proportional to the concentrations of contrast agent in present study, and all stenotic segments of vascular model were displayed by CE-MRA with GD-DTPA at lower concentration of 1.5 mmol/L. As for MRA images of 78 diabetic patients with low dose Gd-DTPA, about 97.4% (76/78) showed diagnostic image quality for pelvic and thigh stations. But the MRA images of lower extremities were interfered by the venous contamination significantly (P ＜ 0.01 ). Compared with DSA for 22 patients, the diagnostic sensitivity, specificity and agreement coefficient (Kappa value) of MRA were 96. 0% ( 168/175), 73.3%(33/45), and 0.72 (P＜0.01), respectively. Conclusion Using 3.0 T MR scanner, high quality CE-MRA of lower limb arteries can be obtained for clinical applications with contrast agent dose as low as 13 ml,which has comparable diagnostic sensitivity and specificity with DSA. But the limitation of venous contamination in MRA image should be resolved in further studies.
