Chinese Journal of Postgraduates of Medicine 2011;34(33):8-10
ObjectiveTo observe the effect of probucol combined with atorvastatin in treatment of stenosis carotid atherosclerosis.MethodsEighty-six patients with stenosis carotid atherosclerosis were separated into two groups with 43 cases each by random digits table.The patients were treated with probucol combined with atorvastatin in observation group and atorvastatin only in control group.The changes of arteriosclerotic plaque and blood fat pre- and poet-treatment were observed.Results There was no significant difference in the levels of lumen area (LN) and intima-media thickness (IMT) pre-treatment between two groups (P> 0.05).Compared with pre-treatment,the levels of LN and IMT post-treatment were significantly decreased in observation group(P < 0.05 ),while no significant difference in control group (P >0.05).There was significant difference in the levels of LN and IMT post-treatment between two groups [(0.59 ±0.19) cm2 vs.(0.72 ±0.28) cm2,(2.76 ±0.41 ) mm vs.(3.27 ±0.57) mm](P< 0.05).There was no significant difference in the levels of total cholesterol (TC),triacylglycerol (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) pre-treatment between two groups (P >0.05).Compared with pre-treatment,the levels of TC,TG,LDL-C post-treatment were decreased,HDL-C was increased,there were significant differences (P < 0.05 ).Post-treatment,the levels of TC,TG,LDL-C in observation group were lower and HDL-C was higher than those in control group (P < 0.05).Conclusion Probucol combined with atorvastatin in treatment of stenosis carotid atherosclerosis can improve arteriosclerotic plaque and low blood fat,which can be applied in clinic.
2.The study on the induction of specific immune cytotoxic T lymphocyte responses against pancreatic cancer by transfected dendritic cells with common tumor antigen survivin mRNAs in vitro
Chinese Journal of Digestion 2011;31(7):433-437
Objective To investigate the induction of specific anti-tumor immune response by transfected dendritic cells (DCs) with survivin mRNA of human pancreatic cancer, and to provide the experimental evidences for the treatment of human pancreatic cancer with DCs vaccine. Methods DCs were isolated and cultured from peripheral blood mononuclear cells (PBMCs). After being transcripted and amplified, survivin mRNA was transfected into DCs by electroporation. The expression of survivin in DCs at different time points was detected by quantitative real-time PCR. The survival rate of DCs before and after transfection was determined by MTT method. The induction of specific cytotoxic T lymphocyte (CTL) response by survivin mRNA transfected DCs was measured by 51Cr standard cytotoxicity test. The induction of specific CTL activation by survivin mRNA transfected DCs was evaluated through testing released IFN-γ by ELISA method. Results After survivin mRNA transfection for 48h, the expression of survivin mRNA in DCs reached the highest point (46.09±6.57). After transfection, the survival rate of DCs was stabilized around 80%. The DCs transfected with survivin mRNA could effectively induce HLA-A2+ / survivin+ specific CTL immune responses. Stimulated with pancreatic cancer cell line Capan-2 cells or SCL-1 cells as control group, the IFN-γ released in 24 hours by survivin specific CTL were (28.79±5.70) U/ml and (25.12±2.13) U/ml respectively, there was no significant difference (P=0.761). Conclusion The induction of CTLs by DCs transfected with human pancreatic cancer survivin mRNA could produce specific anti-tumor immunity.
3.Advances in radiation therapy for early stage breast cancer
China Oncology 2006;0(09):-
Radiation therapy plays an important role in the multidisciplinary treatment of early stage breast cancer. While breast conservative treatment has become an established strategy, recent clinical investigations focus mainly on the possibility of modification to the standard practice, including the significance of tumor bed boost after whole breast irradiation, the criteria for low-risk patients not to receive adjuvant radiotherapy after breast conservative surgery and the feasibility of partial breast irradiation. Post-mastectomy radiotherapy to the chest wall and regional lymph nodes in high-risk patients has been proved to reduce the local-regional recurrence by 2/3. However, only a few trials support the improvement of survival, and significant controversy exists concerning the role of post-mastectomy radiotherapy in intermediate-risk patients. Current review summarizes the advances and controversies stated above for the treatment of early stage breast cancer.
4.Mechanism of CCL2/MCP-1 in its relevant diseases
Chinese Pharmacological Bulletin 2016;32(12):1634-1638
Chemokine is a small protein which plays an impor-tant role in men's physiological function.It has chemotactic ac-tivity and is often secreted by immune cells and glial cells like microglia or astrocytes.Through the effect of chemokine recep-tors on target cells,various immune cells can achieve directional migration and play an important role in the diseases related with immunity and inflammation.CCL2,also known as monocyte chemotactic protein-1 (MCP-1 ),is one member of chemokine CC subfamily (βsubfamily).It can chemokine monocytes, macrophages and T lymphocytes to affect their phagocytosis func-tion and produce antibodies to combat invading microorganisms. In recent years,it has been found that CCL2 plays a key role in the occurrence and development of the problems concerning cen-tral nervous system and immune system as well as cancer, AIDS,leukemia,diabetes and other diseases.This thesis is to give an elaboration on the latest research on CCL2 and the rele-vant diseases.

8.Research progresses on relationship between Wnt inhibitory factor-1 and tumor
China Oncology 1998;0(04):-
WIF-1 is an important antagonist in the Wnt/?-catenin pathway.As a tumor suppressor, WIF-1 is down-regulated in majority cancers but when it is correlated with WIF-1 promoter hypermethylation and treated with demethylation drug, its expression can be restored.Functional loss of WIF-1 due to promoter hypermethylation plays an important role in a tumor's pathogenesis, possibly mainly through aberrant canonical Wnt/?-catenin signal activation.The correlation of the expression of WIF-1 with clinicopathological features in different cancers is not identical.Detecting WIF-1 and promoter hypermethylation may offer help for early diagnosis, therapy and predicting prognoses.
