Objective To investigate the effects of methylated CpG islands in the promoter region on the expression of killer cell immunoglobulin-like receptor 3DL1 (KIR3DL1).Methods Three voluntary unpaid blood donors carrying high expression allele KIR 3DL1*01502 and three donors carrying low expres-sion allele KIR3DL1*005 were recruited in this study .The nucleotide sequences and the methylated CpG islands in the promoter regions of KIR 3DL1*01502 allele and KIR3DL1*005 allele were analyzed .The NK cells expressing KIR3DL1*01502 and KIR3DL1*005 were respectively treated with 5-aza for the dem-ethylation of CpG islands within the promoters .The expression of KIR3DL1 protein on the surface of NK cells was measured with flow cytometer .Results Two differences at nucleotide sites -65 and -269 were detected within the promoter regions of KIR3DL1*01502 and KIR3DL1*005, resulting in two distinct CpG islands.The CpG islands within the promoter of KIR 3DL1*01502 allele were highly methylated .The ex-pression of KIR3DL1 protein on NK cells which carried KIR 3DL1*01502 allele was significantly increased after the demethylation of CpG islands .However , the treatment of demethylation had no significant effects on the expression KIR3DL1 protein on NK cells harboring KIR3DL1*005 allele.Conclusion The methylated CpG islands within the promoter of KIR 3DL1*01502 allele affected the antigen expression on the surface of NK cells.Different KIR3DL1 alleles might show different mechanisms in regulating antigen expression .

This article was aimed to study the inhibitory effect of ginseng polysaccharide injection on tumor growth a-mong ICR mice after inoculation of S180 cells, and its immune mechanism as well as its synergic effect in reducing toxicity of cytoxan (CTX). The experiment was carried out in ICR mice after inoculation of S180 cells. The mice were randomly divided into the model group, the control group, the CTX group, and the drug combination group. After 10 days of medication, the inhibition of tumor growth, WBC, thymus index and spleen index were measured in mice dur-ing the experiment. The immunodepressed mice model was induced by CTX. Effects of ginseng polysaccharide injec-tion on serum hemolysin and monomuclear macrophage phagocytosis were evaluated. The results showed that the com-bination of ginseng polysaccharide injection and CTX can significantly increase the tumor inhibiting rate. It can also reduce the side effect and toxicity of CTX, which may improve the immunosuppression induced by CTX. It was con-cluded that ginseng polysaccharide injection can increase the therapeutic effects and reduce the toxicity of CTX.

Objective To compare the levels of the serum pepsinogen (PG) in the gastric diseases, and explore the diagnostic value in gastric diseases. Methods Two hundred and fourteen patients who had undergone endoscopy were selected, and the patients were divided into 3 groups according to the results of endoscope pathological diagnosis:chronic superficial gastritis (CSG) group ( 70 cases), chronic atrophic gastritis (CAG) group (86 cases) and gastric cancer (GC) group (58 cases). The quantitative chemiluminescence method was used to test serum PGⅠand PGⅡ, and the PGⅠ/PGⅡratio (PGR) was calculated. Results The PGⅠin GC group was significantly higher than that in CAG group: (78.41 ± 55.42) μg/L vs. (53.10 ± 30.08) μg/L, and there was statistical difference (P<0.05). There was no statistical difference in PGⅠbetween GC group and CSG group (P>0.05). The PGⅡin GC group was significantly higher than that in CAG group and CSG group: (23.26 ± 17.80) μg/L vs. (13.12 ± 10.23) and (13.78 ± 9.26) μg/L, the PGR was significantly lower than that in CAG group and CSG group:3.67±2.03 vs. 4.88 ± 1.82 and 5.24 ± 1.88, and there were statistical differences (P<0.05). Helicobacter pylori (Hp) was detected in 165 patients, with positive in 29 cases (Hp positive group) and negative in 136 cases (Hp negative group). There was no statistical difference in PG Ⅰ between Hp negative group an Hp positive group:(60.46 ± 45.49)μg/L vs. (72.41 ± 31.85)μg/L, P>0.05. The PGⅡin Hp positive group was significantly higher than that in Hp negative group: (19.58 ± 1.57) μg/L vs. (14.09 ± 13.21) μg/L, the PGR was significantly lower than that in Hp negative group: 3.82 ± 0.18 vs. 4.99 ± 0.18, and there were statistical differences (P<0.05). Conclusions Compared with that in the CSG and CAG patients, the PG Ⅱ in GC patients increases significantly, while PGR descends significantly, but PG Ⅰ has no correlation with the risk of GC. The PG Ⅱ combined with PGR can predict people with high risk of GC, and help with the judgment of Hp infection.

Aim To investigate the effects of Sanjie Zhentong capsule on cultured mouse myometrial cell contraction induced by prostaglandin F2α( PGF2α) , and to elucidate the mechanism of Sanjie Zhentong capsule in treating dysmenorrheal. Methods Primary mouse myometrial cells were cultured and identified. Intracel-lular calcium ( [ Ca2+] i ) was monitored under a Flex-Station 3 Benchtop Multi-Modo Microplate Reader u-sing Calcium 6-QF. Myometrial cells were labeled to observe the changes of contraction. The expressions of calmodulin ( CaM ) , myosin light chain kinase ( ML-CK) , myosin light chain phosphorylation( p-MLC20 ) in mouse uterine smooth muscle cells ( USMCs ) were determined by immunofluorescence. Results Sanjie Zhentong capsule suppressed the intracellular[Ca2 + ]i inflow and reduced the areas of myometrial cells induced by PGF2α. Then it significantly decreased CaM and p-MLC20 levels. Conclusion Our results indicate that Sanjie Zhentong capsule has inhibitory effect on dysmenorrheal induced by PGF2α. Furthermore,its major mechanism may be related with the regulation of intracellular[ Ca2 + ]i inflow and the levels of CaM and p- MLC20.

Objective To investigate the expression of miR-424* in 2 and 4 Gy X-ray irradiated A549 cells in vitro and in vivo,as well as in clinical lung tissues and serum sample of non-small cell lung cancer(NSCLC) patients,and to explore its potential role in the diagnosis and prognosis of lung cancer.Methods A549 cells were irradiated with 2 and 4 Gy X-rays,and some of irradiated cells were injected into nude mice through tail vein.Real time quantitative PCR (RT-qPCR) assay was employed to detect the expression of miR-424 * in 2 and 4 Gy X-ray irradiated A549 cells in vitro and in vivo,as well as in clinical lung tissues and serum sample of lung cancer patients.Results Compared with the control group,the expression of miR-424* was up-regulated significantly in X-ray irradiated A549 cells at 1,2,12,24 and 48 hpost irradiation,respectively (2 Gy:t =-45.886--6.709,P ＜0.05;4 Gy:t =-29.087--7.833,P ＜ 0.05).Furthermore,the expression of miR-424 * was up-regulated in the lung and serum of nude mice with injection of 0,2 and 4 Gy X-ray irradiated A549 cells,compared with control group (fold change was 9.72,8.58 and 4.7 with 2 Gy irradiation and 11.93,9.22 and 8.99 with 4 Gy irradiation,t=-13.243,-12.409,-9.833 in lung andt=-6.436,-3.052,-3.609 in serum,respectively,P ＜ 0.05).Out of 11 tissue samples of NSCLC patients,6 were detected with up-regulated miR-424* expression,and no significant discrepancy of miR-424* expression was detected in two type of NSCLC tissue samples.On the contrary,43 serum samples were detected with up-regulated miR-424* expression out of 84 serum samples (51.20％) of NSCLC patients (fold change range 1.97 to 17.71),and significant discrepancy of miR-424* expression was shown in two subtypes of NSCLC serum samples [adenocarcinoma:39.10％ (18/46) and squamous carcinoma:65.8％ (25/38)],as well as in serum samples of NSCLC patients with radiotherapy [41.5％ (22/53)] and without radiotherapy [67.7％ (21/31)] (t=5.919,5.387,P ＜0.05,respectively).Conclusions 2 and 4 Gy X-ray irradiation could up-regulate the expression of miR-424* in A549 cells,which might be correlated with the enhanced metastasis of A549 cells induced by X-ray in vivo and in vitro.Furthermore,the expression of miR-424* was up-regulated in over 50％ of the tissue and serum samples of NSCLC patients,which might be correlated with the diagnosis of NSCLC subtype and prognosis of radiotherapy.
