Objective To explore the management alternatives to tr aumatic periprosthetic femoral fractures after hip replacement. Metho ds A retrospective analysis was done on five cases of traumatic perip rosthetic femoral fractures posterior to hip replacement admitted in from June 1 998 to June 2003. There were two males and three females, with age range of 52- 71 years (average 59 years). One case suffered from traffic accident and the oth er four from slipping. Three cases had received hip replacement for femoral head aseptic necrosis, the other two for femoral neck non-union. Total hip replacem ent was carried out in four cases (five hips) and femoral head replacement in on e. These traumatic periprosthetic fractures occurred from one month to 17 years after hip replacement. According to classification to periprosthetic fracture of Vancouver (1995), there were 3 cases of type B and 2 type C. Two cases (one cas e of type B and one type C) were treated with traction and conservative treatmen ts, two (type B) with long shaft prosthesis revision combined with shape memory saw tooth embracing fixator or wires and one (type C) with anatomical plate inte rnal fixation. Results All 5 cases were followed up for f rom two months to five years and attained fracture union with no complications s uch as infection, nonunion or fixation breakage. Conclusions Traumatic periprosthetic femoral fractures after hip replacement are hard to deal with. The management alternatives differ according to fracture site, prost hesis loosening, bone quality and general status of patients. Classification cri teria and corresponding managements of periprosthetic fractures of Vancouver are proved to be suitable guidelines.

OBJECTIVE:To investigate the protective effect of Polydatin on acute lung injury following endotoxic shock in rats.METHODS:Using a rat endotoxic shock model,animals were randomly divided into4groups∶sham operation group,en?dotoxic shock group,Polydatin treatment group and Polydatin pretreatment group.MAPs(mean artery pressures)were mea?sured at given time points.At the end of the experiment,the serum,the lung tissue,and the bronchoalveolar lavage fluid(BALF)were collected.The levels of lung coefficient,lung penetrating index(LPI),the protein concentration of BALF and the content of NOS in the lung tissue were measured.Furthermore,the histologic changes of the lung were observed under light micro?scope.RESULTS:In addition to prohibiting the dropping of MAP,Polydatin could mitigate the acute lung injury induced by endotoxin which increased the levels of lung coefficient,LPI,the protein concentration of BALF and the content of NOS in lung tissue.Enough morphological evidence could be found in pathological sections.Especially,the protective effects were more ob?vious in Polydatin pretreatment group.CONCLUSION:Polydatin has prophylactic and therapeutical effects on acute lung injury following endotoxic shock and the prophylactic effect is more marked than the therapeutic one.

Objective To observe the effect of daidzein on intima proliferation of rat common carotid artery injured by balloon. Methods 24 male Wistar rats were randomly assigned to 3 groups, 8 rats per group: high dose daidzein group (100 mg/kg?d), low dose daidzein group (50 mg/kg?d) and dissolvent control group. Duplicate the rat common carotid arteries injured by balloon models. Five weeks after operation, serum biochemical indicator such as TC, TG, BUN, ALT and MDA were measured using routine biochemical methods. And pathological sections of common carotid arteries were observed and the changes of vascular histomorphology were estimated by computer analysis of photomicrograms. Results Compared with control group, the intima areas was significant decreased in high dose group and low dose group (86 893?83 452 ?m2 vs 199 419?103 352 ?m2 vs 222 324?56 154 ?m2,P0.05). Conclusion Daidzein can inhibit the intima proliferation of Wistar rat common carotid arteries injured by balloon.

Background Isoliensinine(IL) is a kind monomer alkaloid of double benzyl group quinoline separated from Plumula nelumbinis,which has been speculated to have antiarrhythmic effect,Ca~(2+) and?1-receptor blockade, and reversal the left ventricular hypertrophy(LVH).It has been reported the activity of Sarco/Endoplasmic reticulum Ca~(2+)-ATP_(ase)(SERCA) in essential hypertention(EH)/LVH patients was lower than that of healthy people. Objective To investigate the effects of Isoliensinine on left ventricular hypertrophy and activity of SERCA in 2 kidney 1 clamp(2K1C) hypertensive rats.Methods 2K1C hypertensive rats were randomly received Isoliensinine (RHR-IL,5 mg/kg per day p.o,n=16) or placebo.Blood pressure,left ventricle mass index(LVMI) and the activity of myocardial SERCA were measured after 10 weeks treatment.Six untreated SD rats were served as control. Results Isoliensinine decreased BP and LV/BM ratio(IL:136.4?14.6 vs control:189.8?4.4 mm Hg,P

HSU17714 gene is a novel human colorectal carcinoma related gene isolated by subtractive hybridization method. The recombinant antisense expressive plasmid of HSU17714 gene was constructed by inserting the partial sequence (2612 bp) of this gene into the multiple cloning site of the vector pREP9 inversely. Then, it was transferred into human colon adenocarcinoma cells (SW1116) through liposome mediation. Obtained from the two-layer soft agarose culture test, flowcytometry test and cell growth rate detection, the data indicated that the antisense HSU17714 could inhibit the growth of SW1116 cells at different degrees. So, a conclusion could be drawn that the antisense HSU17714 gene expressive vector plays a role in the inhibition of SW1116 cell growth.

Objective To contrast and observe the bone marrow stem mobilization induced by Yiqi Wenyang Huoxuefang and G-CSF,and the influence to left ventricle reconstruction. Methods Model rat was made by ligate LAD,quantity of circulation stem cells(CSC) at the first,fifth and tenth day was detected. After be treated 8 weeks,the heart index,the expansion index and the thinning ratio were calculated. Results The quantity of CSC of Chinese herbs group increased at the fifth day(P
