1.Effect and significance of ICAM-1 in ischemia/reperfusion injury
Journal of Medical Postgraduates 2001;14(1):65-68
Accumulation and infiltration of polymorphonuclear leukocytes are pivotal factors in accelerating cell apoptosis and death in ischemia/reperfusion(I/R) injury, however, adhesion molecules play an important role in its rolling,latching and infiltrating. The goal of the review is to explore the effect and significance of intercellular adhesion molecule-1(ICAM-1) in ischemia/reperfusion.

Chinese Medical Ethics 1994;0(06):-
Joint -Up Community is crucial to the community health services. Joint - Up is an kind of co -operation, but it is neither the co - operation of bureaucracy nor that of the market model. The new relationship of Joint - Up is based neither on responsibility nor on contract, but on equal partnership. It is vital to solve the ethical plight of health services in country.
3.Application of Trihexyphenidyl in Dystonia in Children with Cerebral Palsy (review)
Chinese Journal of Rehabilitation Theory and Practice 2012;18(10):919-921
Dystonia is common in children with cerebral palsy. It can cause motor dysfunction, and is frequently associated with altered speech articulation, abnormal swallowing, and excessive drooling. Although trihexyphenidyl (Artane) is an anticholinergic agent with a long history of use in the management of dystonia in adults, information is limited regarding the use of trihexyphenidyl in children. This study reviewed the clinical experience of the use of trihexyphenidyl in children with cerebral palsy for dystonia, with special emphasis on benefits and tolerability.

1.15). Rosiglitazone at the concentration of 1.25 ?mol?L -1 augme nted the induction apoptosis of A549 cells by treatment with Cisplatin at variou s concentrations of 1.98 mg?L -1, 2.8 mg?L -1 and 4.0 mg?L -1 . A549 cells treated with Rosiglitazone at concentration of 1.25 ?mol?L -1 domostrated nuclear traslocations of PPAR? protein and down-regulation of Bcl-2 protein. Conclusion The ligand of PPAR? Rosiglitazone enhanc ed the inhibition of proliferation and induction of apoptosis by treatment with Cisplatin in A549 cells cultured in vitro. Activation of PPAR? protein and the down-regulation of Bcl-2 possiblely play an improtant role in chemosenstiz eic mechanism of Rosiglitazone in vitro.

AIM To investigate the poteintation of adriamycin induced apoptosis by neferine in resistant human breast cancer cell line MCF 7/Adr. METHODS Apoptosis was detected by PI stain flow cytometry and Tunel assay. The intracellular adriamycin (ADR) accumulation was assayed by HPLC and the expression of P gp was determined by flow cytometry. RESULTS (1)MCF 7/Adr cells resisted the apoptosis induced by ADR while Nef augmented ADR medidated apoptosis; (2) Nef (10 ?mol?L -1 ) increased the accumulation of ADR up to 2 88 fold in MCF 7/Adr cells but not in sensitive cells MCF 7/S; (3) Nef(10 ?mol?L -1 ) reduced the expression of P gp in MCF 7/Adr cells. CONCLUSIONS Nef can overcome apoptosis resistance in MCF 7/Adr cells and its mechanisms are involved in the augment of ADR accumulation and the down-modulation of P gp expression in MCF 7/Adr cells.

Aim To explore the role of a peroxisome proliferators-activated receptor gamma ligand,Rosiglitazone,in angiogenesis in human lung adenocarcinoma cells with reference to the regulation of vascular endothelial growth factor(VEGF).Methods Human lung adenocarcinoma A549 cell line was cultured in vitro.Expression of PPAR? and VEGF in A549 lung adenocarcinoma cells treated with different concentrations of Rosiglitazone was examined by semi-quantitative RT-PCR and immunohistochemical staining.Results PPAR? protein levels were higher in cultured A549 cells.RT-PCR and immunohistochemical staining showed that PPAR? mRNA and protein were enhanced in cells treated with Rosiglitazone in a dose-dependent manner,compared with those of untreated cells.Rosiglitazone had a potent inhibitory effect on the expression of VEGF in A549 cells dose-dependently in a range of concentrations.The effect was maximal with 10 ?mol?L~(-1) RSG and weaken over 20 ?mol?L~(-1) RSG,whereas 100 ?mol?L~(-1) RSG didnot have this down-regulation.GW9662,a PPAR? antagonist,partially blocked this effect of Rosiglitazone.Conclusions Activation of PPAR? suppresses angiogenesis in human lung adenocarcinoma.This action is probably associated with the down-regulation of angiogenic factor,VEGF,which may be modulated by PPAR?.These results suggest that PPAR? might be a novel molecular target for angiogenesis lung adenocarcinoma.

Aim To investigate the molecular mechanism of Rosiglitazone on the expression of integrin ?1 in lung pulmonary carcinoma A549 cell line. Methods RT-PCR and flow cytometry methods were used to examine the expression of mRNA and cell total protein of PPAR? and integrin ?1 subunit. Results The expression of PPAR? mRNA and integrin ?1 mRNA had dose-dependent regulating action by Rosiglitazone,using PPAR? inhibitor GW9662 and ERK pathway inhibitor PD98059 could abolish the inhibition of PPAR? on the expression of integrin ?1. Conclusion The effect of PPAR? ligand Rosiglitazone on integrin ?1 expression is mediated through PPAR?-dependent signaling parthway. The mechanism may be partly involved in ERK pathway.

Objective To investigate the effect of Rb protein expression on the clinical response of the colorectal cancer patients perfused with 5-Fu before operation. Methods The expression of Rb protein in 34 cases of the colorectal cancer sample was determined by streptavidin-peroxidase(S-P) immunohistochemical method and the positive reactions were analysed by ICM-100 Cell DNA Picture Analysis System. The apoptotic rate of colorectal cancer cells was examined by the TUNEL staining. The chemosensistivity of the colorectal cancer cells were tested by the MTT colorimetric assay of agar culture. The clinical response of the colorectal cancer patients perfused with 5-Fu before operation was observed simultaneously. Results ⑴There was the negative correlation between the resistance index of the colorectal cancer cells to 5-Fu (IC50/10-1 peak concentration) and the apoptotic rate of the colorectal cancer cells induced by 5-Fu (?=-0.53,t=-4.91,P1.0 belongs to the group of resistance,
