Objective To observe the k-ras mutation rate of colorectal cancer in China, and assess the effect and toxicity in advanced colorectal cancer (CRC) patients (pts) receiving chemotherapy combined with monoclonal antibody against Epidermal Growth Factor Receptor (EGFR). Methods The k-ras mutation of 139 samples collected from our hospital were tested by pyrophosphoric acid sequencing. Twenty-three advanced colorectal cancer patients were treated with chemotherapy combined with anti-EGFR monoclonal antibody, including 3 initial treated and 20 retreated. In the total 23 patients, 18 were treated with cetuximab and chemotherapy, and S were treated with nimotuzumab and chemotherapy. Cetuximab was taken with 400 mg/m2 first time, and then 250 mg/m2 every week. Nimotuzumab was taken with 400 mg first time, and then 200 mg every week. Eight patients of the total 23 received anti-EGFR monoclonal antibody combined with irinotecan, 12 with FOLFIRI, 3 with FOLFOX4. Results k-ras mutation type (mt) was detected in 39.6 % (55/139) of pts, k-ras wild type (wt) was 60.4 % (94/139). In 22 effect evaluable patients, 5 received PR and 9 SD, and RR and DCR were 22.7 % and 63.6 %, respectively. TTP was 124 days. Thirteen of the 22 patients tested k-ras mutation, of the 11 k-ras mt pts, 4 received PR, 4 SD and 3 PD. Two patients of k-ras mt received PD after 2 cycles treatment. Acneform eruptions were observed in 15 patients of 18 pts who received cetuximab and paronychia in 3 pts. Eruption or paronychia was not observed in all patients who received nimotuzumab. Grade 3 hypersensitivity were occured in 2 patients with cetuximab, and one of them alternated nimotuzumab in next cycle didn't get hypersensitivity any more. Conclusion The mutation rate of k-ras in Chinese colorectal cancer patients was similar with westerners. The effect of cetuximab combined with chemotherapy on advanced colorectal cancer was reliable. Nimotuzumab combined with chemotherapy worth to be studied further because of the promising effect and mild toxicity.

Objective Antiangiogenesis therapy has been shown to prolong survival for patients with malignant tumor .However the present study has not been observed the clinical benefit of antiangiogenesis therapy combination with chemotherapy treated with gastric canc-er.Human recombinant vascular endothelial inhibition (endostar) as a multi-targeted anti-angiogenesis drug, the mechanism is different from other Antiangiogenesis drugs.It can block different pathways of signal transduction to inhibit angiogenesis .This study aimed to observe the effect of combined application of endostar and paclitaxel on biological behavior of gastric cancer cell lines . Methods MMT assay and Tr-answell invasion assay were respectively used to examine the inhibition rate of cell growth and invasion ability when cells were treated with va-rious concentrations of endostar and paclitaxel alone or in combination.The protein expressions of VEGF,MMP-2 and MMP-9 were examined by Western blot. Results Endostar or paclitaxel effectively inhibited the growth of MGC803 cells and the in vitro invasion of MGC803 cells in a concentration-dependent manner.The proliferation and invasion ability of combined treatment with endostar and paclitaxel was significantly lower than that of endostar or paclitaxel alone (P<0.05).Compared with con-trol group, the VEGF,MMP-2 and MMP-9 protein expressions were de-creased in experimental groups ( P <0.05).Compared with paclitaxel group, the VEGF, MMP-2 and MMP-9 protein expressions were relatively reduced in combination groups (P<0.05). Conclusion Endostar combined with paclitaxel can suppress the growth and invasion of MGC803 cells, and the decreasing VEGF , MMP-2 and MMP-9 expressions may be involved in the mechanism .

Objective To evaluate the homing molecules expression of CD49d, CCRg, CD62L on T lymphocytes in AIDS patients before and after treatment with HAART. Methods The study was per-formed in 42 cases of AIDS patients and 18 cases of healthy controls. The expression of CD49d, CCR9 and CD62L on T lymphocytes in AIDS patients and healthy controls were analyzed by flow cytometry. Software BD FACSDiva was used to calculate the percentage of expression. Results The number of peripheral CD4~+ T lymphocytes in group on-HAART was significantly increased compared with group pre-HAART (P<0.01) ; the frequency of CD3~+ CD49d~+, CD3~+CCR9~+, CD3~+CD62L~+, CD3~+CD4~+, CD4~+CD49d~+,CD4~+CCR9~+, CD4~+CD62L~+, CD8~+CD49d~+, CD8~+CD62L~+T lymphocyte in group pre-HAART were statistically decreased compared with group on-HAART and controls(P<0.05) ; The frequency of CD3~+ CD8~+ T lymphocytes was significantly increased compared with group on-HAART(P<0.05) ; the frequency of CD3~+ CCR9~+, CD8~+CCR9~+, CD8~+CD62L~+ T lymphocytes in group on-HAART were significantly de-creased than controls (P<0.001). Conclusion Not only the number of T lymphocytes sub-group, but the expression rate of gut homing molecules CD49d and CCR9, lymph node homing molecule CD62L on T lym-phocytes was changed in AIDS patients : the lower expression frequency of gut homing molecules CD49d and CCR9, lymph node homing molecule CD62L. Anti-virus therapy could partially reverse the immunologic pathological phenomena. CD49d, CCR9 and CD62L may be suggested to indicate the progression of AIDS and immunologic reeonstitution after HAART.
