[Objective]To explore the roles of TIDC(tumor infiltrating dendritic cell)and TIL-T(tumor infiltrating T lymphocyte)in tumor immunity of EBV-associated gastric carcinoma(EBVaGC)and their clinical significance.[Methods]TIDC and TIL-T in EBVaGC(n=49)and EBVnGC(EBV-negative gastric carcinoma)(n=20)were detected by immunohistochemistry method and then their subtypes and their relationships with clinical and pathological factors were analyzed.[Results]Mild infiltration was detected in 29 of 49(59.2%)EBVaGCs and 18 of 20(90%)EBVnGCs,while marked infiltration of TIDC was detected in 20 of 49(40.8%)EBVaGCs and 2 of 20(10%)EBVnGCs.And the difference between the two groups was significant (P=0.013).The number of TIL-T in EBVaGC was hisher than that in EBVnGC(P=0.017),and most of them were CTLs.The number of TIL-T was positively correlated with that of TIDC(r=0.386,n=49,P=0.006).The degree of TIL-T infiltration in EBVaGC had negative relationship with the lymph node metastasis(P＜0.001),while TIDC had no relationship with the clinical features.[Conclusion]TIDC and TIL-T may play important roles in the tumor immunity of EBVaGC;TIDC may contribute to the TIL-T recruitment in EBVaGC.

Objective: To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL. Methods: Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL. Results: A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β＇= -0.179 ), diopter ( β＇= 0.208 ), eyesight with glasses ( β＇= -0.229 ) and anxiety ( β＇= 0.439 ) were influencing factors for VRQL. Conclusion The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

Objective To examine the relationship between smoking and tobacco-related mortality in a cohort of the aged Chinese armymen.Methods A cohort study was carried out in Xi'an,China from 1987 to 2005.A total of 1 268 retired male military cadres aged 55 or older were examined in 1987 and followed up in the next 18 years.At baseline,388 men were non-smokers,461 were former smokers,and 419 were current smokers.The current smoking rate was 33.04%,Quitted rate was 52.39%.The terminal main observation items included all-cause and tobacco-associated mortality.Results Up to Jun 30,2005,a total of 491 subjects died.Compared with non-smokers,the relative risks(95% confidence intervals(CI)) of ever-smokers for all-cause deaths,chronic obstructive pulmonary disease(COPD),lung cancer,and coronary heart disease(CHD) were 1.24(1.01-1.53),1.91(1.06-3.46),2.91(1.36-6.23),and 1.15(0.68-1.93),respectively.Compared with current smokers,the risks of total mortality and death from lung cancer for former smokers were decreased by 66.7% and 14.98%,respectively.Conclusions Cigarette smoking was a major death risk factor in the cohort and quitting smoking could save lives.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.

Objective: To elucidate the role of A39S mutation of DJ-1 in the onset of Parkinson’s disease (PD) and identify genes for which expressions are abnormally regulated by A39S DJ-1 mutation. Methods: We established HEK293 cell lines which stably expressed empty vector, wild-type DJ-1 and A39S mutated DJ-1 respectively. DNA microarrays were used to identify genes for which expressions change in wild-type DJ-1 cells and A39S DJ-1 mutant cells. Results: Compared with the cell line expression empty vector, we identified 42 differentially regulated genes (including 14 up-regulated genes and 28 down-regulated genes) in the wild-type DJ-1 cells and 8 differentially regulated genes (including 6 up-regulated genes and 2 down-regulated genes) in the A39S DJ-1 mutant cells. Compared with the wild-type DJ-1 cells, only the expression of UGT2B7 gene was down-regulated in A39S DJ-1 mutant cells. hTese differentially regulated genes were mainly related to signal transduction, regulation of transcription, apoptosis and metabolism. Conclusion: A39S mutated DJ-1 may disturb the transcriptional activities of DJ-l and involve in the pathogenesis of PD.

ABSTRACT:Objective To observe the influence of saikosaponin-d (SSd)on the proliferation and the function of autophagy of human hepatocellular carcinoma (HCC)cell line SMMC-7721 to explore the possible mechanisms. Methods SMMC-7721 was cultured invitro and then treated with SSd of various concentrations (5.0,7.5,10.0, 12.5,15.0 and 17.5 mg/L)for 24,48 and 72 h.We used MTT to detect cell proliferation,selected the optimal concentration and time,and detected the expressions of BECN1 at mRNA and protein levels by PCR and Western blot.Results The inhibition rate of the proliferation of SMMC-7721 cell line increased with the increase of the concentration of SSd,and the highest inhibition rate (60%)appeared when the concentration reached 12.5 mg/L. The expression of BECN1 in the group with SSd was obviously higher than that in the control group (P<0.05). 3-MA decreased not only the expressions of BECN1 at mRNA and protein levels but also the expression of BECN1 when used in conjunction with SSd.Conclusion The inhibiting function of SSd on SMMC-7721 presents a dependency between drug concentration and function time,basically in line with the drug dose-effect relationship. SSd induces the occurrence of autophagic cell death through up-regulating the expression of BECN1 ,thus inhibiting the proliferation of SMMC-7 7 2 1 .

Objective To determine the global incidence and risk factors of herpes simplex virus type 2 (HSV-2). Methods Meta-analysis was performed to systematically and quantitatively review all the original research papers and reports that were published in 1990-2010 on the global incidence of HSV-2. Pooled incidence, pooled hazard ratios, publication bias, heterogeneity and sensitivity analysis for those studies were calculated or conducted using Stata 10.0. Results HSV-2incidence varied considerably across different countries, regions and/or populations, with a range from 1.0 to 23.1/100 person-years (PYs). Africa and United States were highly epidemic with HSV-2 while females and HIV-infected people were at higher risk of HSV-2 infection, whereas HSV-1 infection status was not significantly associated with acquisition of HSV-2 infection. Conclusion HSV-2incidence varied considerably among countries, regions and populations, which called for different and tailored control strategies. More research was also needed in China to examine the HSV-2 incidence and risk factors in different regions and populations.
