Objective To evaluate the influence of the alendronate treatment in early-stage adult nontraumatic avascular necrosis of femoral head. Methods The 83 patients with nontraumatic avascular necrosis of femoral head were enrolled in this study. They were given oral alendronate 70 mg weekly, and evaluated with Harris criteria before and after treatment. Results In the patients with ARCO Ⅰ necrosis, the scores of pain and function were higher after treatment than before [(41.45±3.55) scores vs. (38. 48± 5.55) scores, t = 3. 70, P = 0. 001; (45.06 ± 1.50) scores vs. (43.97 ±2.31) scores, t= 3.76, P= 0. 001]. In the patients with ARCO Ⅱ necrosis, the scores of pain,function and activity were also higher after treatment than before [(40. 40±4.31 ) scores vs. (37.32±6. 65) scores, t=4.06, P=0.00; (42.90±2.70) scores vs. (41.66±3.35) scores, t=3.15, P=0.003; (4.76±0.47) scores vs. (4.42±0.70) scores, t=3.35, P=0.002]. Conclusions Alendronate is effective in treatment of early-stage adult nontraumatic avascular necrosis of femoral head, in particular for ARCO Ⅱ patients. But its long-term effect is worth researching in future.

Objective To explore the establishing methods and differences of rat models of spleen deficiency and spleen deficiency liver cancer using the traditional Chinese medicine Dachengqi and Xiaochengqi decoctions .Methods Spleen-deficiency rat models were developed by multifactor methods:bitter-cold purgation ( Dachengqi or Xiaochengqi de-coction), cold-wet environment, tiredness, and fasting on alternate days for 30 days.Seven days after spleen-deficiency modeled,liver cancer in the spleen-deficiency rats and normal rats was developed by subcutaneously inoculation of Walker -256 carcinoma cell line in nude mice and then transplanted into rat livers .Liver cancer models were observed for 35 days. Sixty 3-week old male Wistar rats were randomly distributed into 4 groups: normal group , liver cancer model group , and Dachengqi and Xiaochengqi decoction groups .Degree of spleen deficiency , changes of the body-weight, survival time and tumor formation were recorded .Results Spleen deficiency rat models were successfully established .The weight gain of rats in the spleen-deficiency groups was significantly inhibited (P<0.01), and during the first 20 days (but not later) the average body weight of the Dachengqi decoction group was significantly higher than that of the Xiaochengqi decoction group (P<0.05).Spleen-deficiency scores of rats in the Xiaochengqi and Dachengqi groups were higher than those in the blank tumor group, especially in the Xiaochengqi group (P<0.01).The total tumor formation rate was 91.1%and 80%in the blank tumor groups , and 93.3%in both Xiaochengqi and Dachengqi groups , respectively .The average survival time of Xi-aochengqi group was lower than that of the blank tumor and Dachengqi groups ( P<0.01 and P<0.05 ) .The cumulative survival rate of the Xiaochengqi group and rats with a higher spleen-deficiency score was lower than that of the other groups (P<0.05).Conclusions Xiaochengqi decoction may induce spleen deficiency more seriously than Dachengqi decoction , and spleen deficiency may be an important unfavorable prognostic factor for rat models of liver cancer .

Objective To study the apoptosis-inducing effect of recombinant adeno-associated virus serotype 8 with soluble TRAIL gene on human colon cancer cell line HCT116. Method Recombinant adeno-associated virus serotype 8 with TRAIL gene was generated by triple plasmid transfection of HEK293 cells with phosphate calcium precipitation. After infected by recombinant virus, cell growth assay was carried out by counting alive cells after trypan blue exclusion. Alternations of cell morphology was examined by microscopy. Cell apoptosis was detected by DNA laddering. The protein expressions of apoptosis-3 and apoptosis-8 were detected by Western blotting. Result The growth rate of the AAV8-sTRAIL infected HCT116 cells was significantly inhibited. Recombinant virus induced apoptosis in colon tumor cells by triggering caspase cascade, but not in normal human hepatocytes. Conclusion AAV8-sTRAIL efficiently suppresses the growth of human colon cancer cell line HCT116 by inducing apoptosis, with no evident toxicity to normal cell.

Objective:To evaluate the effect how Subtilisin FS33 affect thrombotic and fibrinolytic systems in vitro and in vivo. Method:Activity of Subtilisin FS33 was measured by clot liquefaction time(CLT) . On the model of 10% FeCl3 induced thrombi of carotid arteries in rats,various doses of Subtilisin FS33 were injected to the rats,and the fibrinolytic effect was observed. Results:0.5 g of the unheated blood clots gradually dissolved within 45 min,whereas the blood clots heated at 80℃ for 30 min dissolved within 3 h. This indicated that the enzyme was able to degrade blood clots in the absence of endogenous fibrinolytic factors. The experiment in vivo indicated that high dose subtilisn group could significantly prolong CT(coagulation time ) ,PT(prothrombin time) ,TT(thrombin time ) ,APTT(activated partial thromboplastin time) ,reduce ELT(euglobulin lysis time) ,decrease the content of FIB(fibrinogen) ,increase the content of FDP(fibrinogen degradation products) . D-dimer of all experimental groups waspositive. The venous thrombus in lung and kidney was dissolved totally or partly as observed by pathological section. Conclusion:Both thrombolytic effects of Subtilisin FS33 in vitro and in vivo were significant and the mechanisms might be associated with enhancing anticoagulation activity and fibrinolysis.
