Effect of chemokines,activity enhanced by mobilization of bone marrow cells on solution and absorption of venous thrombosis

Hao SUN

Journal of Chongqing Medical University.2010;35(1):110-113.

Objective: To discuss the effect of bone marrow mobilization on chemotaxis of aggregation of macrophages in venous thrombosis. Methods:SD adult rats were divided randomly into normal group,sham operation group,thrombus group and rhG-CSF group.Peripheral blood was harvested at 30min before operation and on the 7th and 14th day after operation.Level of MCP-3 in peripheral blood was detected by ELISA.Inferior vena cava specimens of thromus group and rhG-CSF group were collected at postoperative 7th and 14th day. With the application of RT-PCR,expression of MCP-3mRNA in thrombus was detected.Results:The level of MCP-3 in peripheral blood of rhG-CSF group was significantly higher than that before operation and also higher than the levels of MCP-3 in peripheral blood of sham operation group and thrombus group on the 14th day after operation(P<0.05),and the difference was significant.On the 7th and 14th day after operation,compared with thrombus group,the expression of MCP-3 mRNA in rhG-CSF group remarkablely increased,and the difference Was significant beween these two groups(P<0.01).Conclusion:Brone marrow cell mobilization enhances the chemotaxis of MCP-3 on macrophages.

Xinhuan CHEN

Journal of Chongqing Medical University.2010;35(1):100-102.

Objective: The aim of this study was to investigate the immune function and prognosis for patients with primary hepatic cancer who implemented the perioperative enteral immunonutrition support for hepatectomy.Methods: 58 cases of patients with primary hepatic cancer in our hospital in 2003 treated with liver resection were randomly divided into nutritional support fur immune nutrition group and conventional control group.Immune function was detected on admission,1st day and 7th after surgery;5-year follow-up was performed to compare the prognosis of the two groups. Results: Concentration level of CD3+,CD4+,CD8+and CD4+ICD8+in preoperative hepatectomy were the same between the two groups. On the first day after surgery,CD3+,CD4+,CD8+content decreased significantly; there was no difference between the two groups. On the 7th day after surgery,CD3+,CD4+,CD8+content increased;and the intervention group increased more significantly.1,2,3,4,and 5-year survival rates in intervention group and control group were 82.8%,70.2%, 39.6%,22.6%.20.6%and 74.6%,50.1%,25.4%,21.5%,19.5%.The survival rate was higher in the intervention group than the control group at 1-year,2-year and 3-year,while the 4 and 5-yearsurvival rate of the two groups was same,and the intervention group had better overall survival compared with the control group(X~2=3.547,P=0.025).The OR value for enteral immunonutrition support impacting postoperative survival was 0.649 after multivariate analysis adjusted.with 95.0%CI of 0.614-0.686.Conclusion:Enteral immunonutrition support can ameliorate immune suppression in hepatectomy for patients with primary liver cancer during perioperative period,and it also Can improve postoperative survival.

Tong SHEN ; Zicheng HU ; Yong LI ; Yong ZHANG ; Peng XIE ; Fajin LV ; Tianyou LUO ; Jun MU

Journal of Chongqing Medical University.2008;33(Z1):55-59.

Objective:To identify the cerebral activation patterns associated with the processes that occur during viewing Chinese and English words in native Chinese English learners.Methods:12 right-handed Chinese English hamers were divided into two groups equally,namely English majors and non-English majors,and took semantic judgement tasks of both English and Chinese words,for whom the fMRI images were coUected.Results:To various degrees,all subjects demonstrated activation of associated cerebral regions in both hemispheres and the left hemisphere activation was more significant for most subjects.Except for elassieal regions involved in language processing,such as Wemicke areas and Broca areas,there were other activated cerebral regions,including cerebellum,limbic system and basal ganglia nucleus,etc.To sum up,there were apparent overlap for cerebral activation distribution and no specific processing areas for both tasks.The analysis of ROI(region of interest)suggested that subjects in specialized group were more dependent on right hemisphere to perform English words task.Conclus/on:Language cognition is dominated by left hemisphere,which is also shared by the right hemisphere to various degrees and thus two hemispheres work by ways of both dissociation and coordination.It is possible that working strategy of the right hemisphere in English task is related to proficiency of the second language.A variety of distinctions are shared by each subject for language cognitive patterns.

Aiwen ZHANG

Journal of Chongqing Medical University.2000;25(z1):118-120.

Special efforts were made to probe ways of improving the English teaching of the three-year vocational students in our university and enhance their ability to use English. By analyzing the cause of the students＇ failure in last year＇s national standard examination and working out ways to choose appropriate teaching materials and to improve teaching methods, the students＇ overal linguistic level and communication abilities were greatly enhanced. We came to the conclusion that lessons must be taught from our own experience as well as from that of other schools, close attention must be paid to the latest development in English teaching for three-year vocational students in our country and prompt actions must be taken. Only by doing so can we stay in line with the reform of English teaching across the nation.
