Objective:To analyze the frequencies of HLA-A*0201 restricted CEA-specific CD8+T cells, HLA-A*0201/FLUmp tetramer and HLA-A*0201/CAP-1 tetramer were applied in patients with colorectal cancer.Methods: Lymphocytes from peripheral blood and lymph node,1×106 cells/ml,were incubated with 1μg HLA-A*0201/peptide tetramers and anti-CD8 for 1 h at 25 coseperately.The cells were then washed in PBS.Next,the cells were illuminated by detecting frequencies of FLUmp-specific CD8+T cells and CAP-1-specific CD8+T cells with flow cytometry.Results: HLA-A*0201/peptide were used to detect CAP-1 or FLUmp-specific CD8+T cells,which were analyzed either healthy individuals or patients with colorectal cancer.We did not find differences in average frequencies of FLUmp-specific CD8+T cells between 11 HLA-A*0201+patients with colorectal cancer and 14 HLA-A*0201+healthy individuals [ ( 0.671 ±0.421 )%, ( 0.564 ±0.408 )%].But the frequencies of CAP-1-specific CD8+T cells of HLA-A*0201+patients with colorectal cancer showed higher than HLA-A*0201+healthy individuals [ ( 2.409 ± 2.385 )%, ( 0.020 ± 0.021)%respectively],which was statistically significant(P=0.008).Conclusion:The frequencies of CAP-1-specific CD8+T cells in PBMC from peripheral blood and lymph node of HLA-A*0201+patients were increased,showed CEA-specific CTs has a vital role in colorectal cancer.

Objective: To study the effect of curcumin on cardiac remodeling and heart function change induced by adriamycin in rats. Methods: A total of 50 SD rats were randomly divided into blank control group (n=10), adriamycin group (n=20) and curcumin intervention group (n=20). General conditions of rats, including weight, hair color, diet and activity capacity, were observed. Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) and left ventricular end-diastolic dimension (LVEDd) were observed by echocardiography. Rat heart was weighed and levels of cardiac collagen type Ⅰ and Ⅲ were observed using immunohistochemistry method. Results: Compared with blank control group after experiment, there were significant increase in heart weight [(168.53±26)mg vs. (208.34±31)mg], heart weight/body weight [(0.36±0.06) vs. (0.52±0.08)], and significant decrease in body weight [(469.27±34)g vs. (428.47±45)g]; significant increase in LVEDd [(4.87±0.19)mm vs. (7.49±0.83)mm], significant decrease in LVEF [(69.53±6.25)% vs. (41.46±4.38)%] and LVFS [(45.83±3.79)% vs. (17.25±2.92)%] in adriamycin group, P<0.05 all, significant increase in expression rates of collagen type Ⅰ and Ⅲ, P<0.01.Compared with adriamycin group, there were significant increase in body weight (452.46±38)g, significant decrease in heart weight (178.73±38)mg, heart weight/body weight (0.39±0.07); significant decrease in LVEDd (5.96±0.65)mm and significant increase in LVEF (53.12±5.43)% and LVFS (36.57±3.66)%, P <0.05 all; significant decrease in expression rates of collagen type Ⅰ and Ⅲ in curcumin group, P <0.01. Conclusion: Curcumin can improve cardiac remodeling and heart function induced by adriamycin in rats.

Objective To observe the effect of needle warming moxibustion on cognitive dysfunction after stroke. Methods 76 stroke patients with cognitive dysfunction were randomly divided into treatment group (n=38) and control group (n=38). The treatment group received needle warming moxibustion and routine rehabilitation for 4 weeks, while the control group only received routine rehabilitation. They were assessed with Montreal Cognitive Assessment (MoCA) and activities of daily living (ADL) scale before and after treatment. Results The score of MoCA and ADL improved in both groups (P<0.05), and improved more in the treatment group than in the control group (P<0.05) after treatment. Conclusion Needle warming moxibustion could improve cognitive function in patients after stroke and activities of daily living.

Objective To observe the effect of recombinant human mannose-binding lectin (RhMBL)on the expression of Bcl-2 and p53 gene in thyroid cancer cell lines.Methods Two kinds of thyroid cancer cell lines( K1 cells and FTC-133 cells) were dealed with different concentrations of rhMBL( control group:0 mg/L;experimental group:1 mg/L),then total protein was extracted to detect the expression of Bcl-2 and p53 by Western Blot.Results The expression level of p53 and Bcl-2 were observed to be obviously down-regulated after incubation with RhMBL.( 1 ) K1 cells:There was significant difference on the expression of p53 and Bcl-2 between control group and experimental group [ p53:( 1.51 ± 0.29) vs (0.74 ±0.07),t =7.63 ; P =0.040;Bcl-2:( 1.20 ± 0.07 ) vs ( 0.59 ± 0.04 ),t =6.28,P =0.001 ] ; ( 2 ) FTC-133 cells:there was also significant difference on the expression of p53 and Bcl-2 between control group and experimental group [ p53:( 0.88 ±0.14) vs(0.35 ±0.08),t =3.29,P=0.003; Bcl-2:(1.07±0.11) vs (0.33 ±0.06),t =5.73,P=0.000 ].Conclusion Bcl-2 and p53 may play an important role on the induction of thyroid cancer cell apoptosis and inhibition its proliferation by RhMBL.

Hyperuricemia is a risk factor for various diseases, but knowledge on acute hyperuricemia is still not sufficient. The present study was aimed to investigate the effect of acute hyperuricemia on red blood cells from hemorheological point of view, and to provide the reference for clinical treatment. The rats were gavaged with 500 mg/kg hypoxanthine and intraperitoneally injected with 100 mg/kg oxonate to induce the model of acute hyperuricemia. The same volume of blood samples were drawn within time period of 0, 1, 2, 3 and 6 h, respectively, from the inner canthus of rats to measure the serum uric acid, hemorheological parameters and the malondialdehyde level. It was found that in each period of 1, 2 and 3 h, the rats had significantly higher levels of uric acid. The integrated deformation index and relax index were increased. The hemolysis rate was significantly reduced. The plasma malondialdehyde level was obviously decreased at the end of 2 h. The results suggested that short-term elevated uric acid could improve the hemorheological parameters and the lipid oxidative level in red blood cells.

BACKGROUND:Intraarticular hyaluronic acid (HA)has been used as one common method in the treatment of osteoarthritis. But its application in treating Kashin-Beck disease (KBD) is generalizing. The effect of HA on chondrocyte metabolism in KBD patients remains unclear.OBJECTIVE:To investigate the effects of HA on the synthesis of collagen Ⅱ and aggrecan in KBD chondrocytes cultured in vitro to understand its clinical treatment for KBD.DESIGN,TIME AND SETTING:Comparative observation. The experiment was performed in the Laboratory Center of Biomedicine and Endemic Disease Laboratory of College of Medicine,Xi'an Jiaotong University from September 2006 to January 2009.MATERIALS:Samples of KBD were from cartilage and corpus liberum excised from 6 KBD patients undergoing knee joint operation,and normal samples of fresh knee cartilages were provided by 6 people undergoing amputation or death by accident METHODS:Chondrocytes of KBD and normal control were separated and cultured in vitro. Varying dosages of HA (100,500 gm/L) were administered to normal and KBD chondrocytes cultured in vitro for 6 days. Negative control was not treated with HA.MAIN OUTCOME MEASURES:Effects of HA on collagen Ⅱ and aggrecan mRNA expression in KBD patients and normal people by RT-PCR.RESULTS:Compared with normal control group,the mRNA level of collagen Ⅱ and aggrecan were lower in KBD (P＜0.05).After administration of HA (100,500 mg/L) the mRNA level of collagen Ⅱ and aggrecan were significantly increased,and the effects of 500 mg/L was more significant.CONCLUSION:HA can increase the collagen Ⅱ and aggrecan mRNA level of KBD chondrocytes cultured in vitro. In particular,500 mg/L HA significantly promoted chondrocyte metabolism compared with 100 mg/L HA.
