Objective To compare the clinical results of femoral head replacement for femoral in- tertrochanteric fractures and femoral neck fractures in aged patients.Methods Forty cases of femoral in- tertrochanteric fractures and 45 cases of femoral neck fractures (aged over 80 years) underwent femoral head re- placement from August 1996 to April 2002 in our department.The clinical results of the two groups were retro- spectively compared and analyzed statistically.Their follow-up periods,ranging from 3 to 7 years,averaged 4.6 years in the intertrochanteric fracture group and 5.5 years in the neck fracture group.Results The differences in time of hospitalization,perioperative blood loss,postoperative drainage,ambulation trine,early compiications be- tween the two groups were of no statistical significance (P>0.05).The differences in operation time and inequality in leg length after operation between the two groups were of statistical significance (P<0.05).The operation time was longer and more limb-length inequality occurred in the intertrochanteric fracture group than in the neck fracture group.There was no significant difference in Harris score at the last follow-up between the two groups.The X-ray at the final follow-up showed that there was insignificant difference in postoperative hip joint space,hip pain,or stem loosening between the two groups (P>0.05).The stem revision incidences were of no statistical significance be- tween the two groups (P>0.05).The two groups reported no acetabular protrusion.Conclusion With standard cemented prostheses,femoral head replacements can achieve as similar functional outcomes for patients with in- tertrochanteric fractures as for those with femoral neck fractures.

Oxidation and free radicals participate in the pathological process of multiple diseases in organisms, and acupuncture shows good effect in antagonizing oxygen stress (OS). This article reviews the effect of acupuncture in antagonizing oxygen stress and the mechanism of its anti-free radical effect in various diseases. The authors hold that acupuncture not only has a chain-blocking effect, but also has preventive and repairing effects of anti-oxidation. And anti-OS action is one of the important mechanisms of acupuncture.

Objective To explore the anti-inflammatory effect of erythropoietin (EPO) on hepatic ischemia reperfusion (IR) injury in fatty liver rats.Methods A total of 100 male SD rats were fed with high-fat diet for 12 weeks.After the model was successfully established,the fatty liver rats were randomly divided into sham-operation (SHAM),the ischemia-reperfusion (IR) and EPO preconditioning group.Serum ALT and AST as well as hepatic histopathological changes were measured.Xanthine oxidase method was used to detect the liver tissue SOD.Thiobarbituric acid method was used to detect the MDA.Enzyme-linked immunosorbent adsorption assay (ELISA) was used to detect the plasma tumor necrosis factor alpha (TNFαt) and interleukin 1 (IL-1).Results In the EPO preconditioning groups the swelling hepatocytes was observed,but the inflammatory cell infiltration was significantly decreased and no necrosis of hepatocytes was found.ALT and AST in the EPO preconditioning groups were significantly lower than those in IR group (P < 0.05).The levels of SOD activity in the EPO preconditioning groups were significantly higher,but MDA were significantly lower than that in IR group (P < 0.05).The TNF-α and IL-1 in the EPO preconditioning groups were significantly lower than those in IR group (P <0.05).The values of ALT,AST,TNF-α,IL-1 and MDA in the EPO groups were:EPO-1 > EPO-2 > EPO-3 (P < 0.05);but the values of SOD in the EPO groups were:EPO-1 < EPO-2 < EPO-3 (P < 0.05).Conclusions EPO preconditioning has a protective effect against hepatic IR injury in fatty liver rats,possibly through inhibiting the inflammatory reaction to prevent the IR injury.The anti-inflammatory effect of high-dose EPO is better than that of low-dose EPO.

AIM: To construct a recombinant adenovirus vector carrying AFP promoter to specifically express a targeting gene in hepatocellular carcinoma HepG2 cells. METHODS: Based on the Adeno-X~TM Expression system, the CMV promoter was replaced by a 300 bp a-fetoprotein promoter. The EGFP(enhanced green fluorescent protein) gene as a report gene was inserted to the multiple-cloning site(MCS). The normal liver LO2 cells, hepatocellular carcinoma HepG2 cells and HeLa cells were infected by the recombinant adenovirus, respectively. Northern blotting and fluorescence microscope were used to detect the transcription level of EGFP gene and its protein expression, respectively. RESULTS: Northern blotting showed that the target gene was markedly transcribed in HepG2 cells, but slightly in LO2 and HeLa cells. Under the fluorescence microscope, strong EGFP expression was seen in HepG2 cells but very weakly in HeLa and LO2 cells. CONCLUSION: Under the control of the 300 bp human AFP promoter, the target gene carried by the recombinant adenovirus was expressed in the AFP-producing HepG2 cells at a very high level, but not or very weakly in AFP negative cells. This adenovirus system can be used as a new, potent and specific approach for the gene-targeting therapy for the AFP producing primary hepatoma. [

Objective To investigate the effects of heart displacement on hemodynamics during off-pump coronary artery bypass grafting (OP-CABG) while the sites for anastomosis were being exposed. Methods Forty-seven patients of both sexes (36 male, 11 female) aged 50-82 years undergoing OP-CABG were enrolled in the study. Preoperative cardiac function was assessed : class Ⅱ in 22 patients; Ⅲ in 23 and Ⅳ in 2 according to NYHA classification.The mean ejection fraction was 0.55?0.14 before surgery.They received on average 3.2 grafts. Premedication consisted of intramuscular morphine 10 mg, midazolam 3-5 mg and scopolamine 0.3 mg.Before induction of anesthesia ECG and SpO2 were monitored and radial artery was cannulated for continuous direct BP monitoring. Anesthesia was induced with midazolam 0.1 nig?kg-1 , fentanyl 4?g?kg-1 and pancuronium 0.1 mg?g-1 iv.The patients were mechanically ventilated after tracheal intubation and PETCO2 was maintained at about 40 mm Hg. Anesthesia was maintained with isoflurane and 50%-60% N2O in O2 and intermittent intravenous boluses of fentanyl and pancuronium. Swan-Ganz catheter which can continuously monitor mixed venous blood O2 saturation (SvO2) was placed in pulmonary artery via right internal jugular vein. SvO2, cardiac output (CO), BP, pulmonary arterial pressure (PAP) and HR were continuously monitored. Right atrial pressure (RAP) and PAWP were measured intermittently. Cardiac index (CI),stroke index (SI),systemic vascular resistance index (SVRI),PVRI, left and right ventricular work index (LVWI,RVWI) and left and right ventricular stroke work index (LVSWI,RVSWI) were calculated. The hemodynamic parameters were recorded after induction of anesthesia before surgery (T1,baseline),before heart displacement (T2), while anastomosis to anterior descending branch was being made (T3), while anastonosis to right coronary artery or posterior descending branch (T4) and to left circumflex artery or diagonal branch (T5) was being made, after normal heart position was resumed (T6) and at the end of operation (T7). Results While anastomosis to the anterior descending branch was being made (T3) SI and LVSWI significantly decreased as compared with the baseline (P
