    Objective:To investigate the inhibitory effects of 99technetium methylenediphosphonate(99TcMDP) injection on bone invasion by walker 256 carcinoma in rats.Method:The experimental model of bone invasion by walker 256 carcinoma was made with 96 rats .The animals were divided into 6 groups, control group, 8 mg•kg1 bonefos group, and 1, 2, 4, 8 mg•kg1 99TcMDP groups. The rats were injected in abdominal cavity with the drug for 10 days and then were killed on the eleventh day. The tibias’ and tumor tissues’ weights, roentgenogram and histology were examined. Results:The tibias’ weight and the level of bone invasion by walker 256 carcinoma in 4, 8 mg•kg1 99TcMDP groups and bonefos group were significantly lower than those in the control group. The difference between the 99TcMDP group and bonefos group was not significant. The effect of 1 and 2 mg•kg1 99TcMDP did not significantly differ from the control.Conclusion:99TcMDP and bonefos can inhibit bone 99TcMDP increase with increasing doses.

    Objective:To observe effects of ginkgo biloba leave preparation (GBLP) on myocardial ischemia and hemorheololgy in patients with senile coronary artery disease (SCAD).Methods:Seventyeight cases of SCAD were diveded randomly into the treatment group (40 cases) and the control group (38 cases). The control group were treated with conventional method of sorbitrate and aspirin, and the treatment group were treated with GBLP 120mg P.O. tid ,on the basis of the conventional method. Both groups of patients were treated for consecutive 2 months. The parameters of blood lipids and hemorheology were measured and myocardial ischemia was assessed by dynamic electrocardiograms (Holter) before and after the treatment. Results:In the treatment group, the average levels of TC, TG, LDLC were lowered significantly(P<0.01) and HDLC was increased (P<0.05) while in control group, the leves of TC, TG, HDLC and LDLC were not different (all P>0.05) before and after the treatment. Observation on hemorheology showed that whole blood viscosity under low or high shear rate, plasma viscosity, erythrocyte aggregation index, erythrocyte electrophoresis time and specific vilume, and fibrinogen in the GBLP after the treatment were markedly reduced (P<0.01 or P<0.05), the action of ameliorating hemorheologic parameters was superior to that in the control group (P<0.05). Frequency and sustained time of symptomatic and asymptomatic myocardical ischemia were both decreased significantly in the two groups (P<0.01 and P<0.05 respectively) after the treatment, but the dectease was more marked in the treatment group than in the control group. No severe adverse effect was found in the followingup treatment with GBLP.Conclusion:GBLP exerts significant effects on lowering the blood lipids and improrving the conditions of hemorheololgy so as to be helpful in reducing the occurrence of myocardial ischemia. It is an effective and safe drug for the treatment of SCAD.

    Objective:To study the application results of fufuchun capsule in intrauterine sterilizing device withdrawal operation at the later stage of menopause.Methods:80 cases of later stage menopause women were divided into 2 groups, 40 cases in the treatment group took fufuchun capsules for ten days before the intrauterine sterilizing device withdrawal operation, the other 40 cases in the control group take no fufuchun capsule before operation. Results:The operation successful rates in the treatment and control groups were 100.0% and 75.0% respectively. The operation time, difficulties in operation between the 2 groups were different statistically (P<0.01).The other differences between the 2 groups were bleeding, device integrity and selfsensation (P<0.05).Conclusion:In extracting the intrauterine sterilizing device from later stage menopause women, the fufuchun capsules can improve the operation environment of vagina, cervix and uterus, and make the operation easy to perform.

    Objective:To study the effect and side effects of mycophenolate mofetil (MMF) in treating patients with myloperxidase antineutrophil cytoplasmic antibody (MPOANCA) positive patients with LN all were treated with MMF in combination with cirticosteroid. The starting dose og MMF ranged from 1.5 g•d1 to 2.0 g•d1, and followup study lasted for (14.56±5.10) months.Method:Clinical efficacy was defined as remission, partial remission and no responds. The dose of MMF was gradurally reduced to maintenance dose of 0.5-0.75 g•d1 after the patients achieved remission or partial remission.Results:Rensl remission occurred in 10 of 15 patients, 3 patients achieved partial remission, 2 patients achieved remission in 3 months. No obvious side effects were observed during MMF treatment.Conclusion:MPOANCA positive LN is a special type in pathology. The rates of hematuria and injury of renal function were higher than those of the ordinary type. MMF is effective for active glomerular lesion of refractory severs LN and has a higher remission rate in earlier period but less side effects.

    Objective:To compare the effects of two pituitary down regulation protocols triptorelin was administered in assisted reproductive technology (ART) and to study the correlation between serum concentrations of LH and outcome of ART.Methods:402 patients received triptorelin 0.1 mg every other day and 156 patients received triptorelin 0.05 mg daily during the midluteal phase prior to ovarian stimulation for IVF until HCG injection was given. Serum concentration of LH, progesterone and estrodial were measured before HCG injection. Results:Clinical pregnancy rate was 44.5% in 0.1 mg group, much higher than that in 0.05 mg group (P<0.05), in which pregnancy rate was 34.9%, but no significant difference was found in ongoing pregnancy rate between tow groups. The average serum concentration of LH was 2.2 U•L1. There was no correlation between serum concentration of LH and outcome of ART when serum concentration of LH is below 10.0 U•L1. Conclusion:Injection of triptorelin 0.1mg every other day is a effective and convenience protocol to suppress LH surge and no correlation was found between serum concentration of LH and outcome of ART when serum concentration of LH is below 10.0 U•L1.

    Objective:To observe the efficacy of the combination plot of recombinant interferon and ribavirin in the treatment of chronic hepatitis C (CHC). Methods:84 cases of CHC were divided into group A, B and C. The cases of group A were first treated by qd 3 million unit INFα2b, after 4 weeks by qod 3 million unit INFα2b and, in the meantime, were injected by 10-20 mg•kg1 ribavirin. the cases of group B were only treated by INFα2b, the dose being the same as group A. The cases of group C were first treated by qd 5 million unit INFα2b. The use of ribavirin being the same as group A. The HCVRNA and ALT of patients serum were detected by fluorescence quantity PCR and automatic biochemistry analyze. Results:After the 84 chronic hepatitis C patients had been treated for 40 weeks, the ALT persistent response rates of group A and group B were 70.6% and 47.1%. the HCVRNA persistent response rate were 50.0% and 26.5%. There was significant difference between the two groups(P<0.01). The ALT and HCVRNA persistent response rate of group C is 62.5% and 43.7%, There is significant difference between the cases of group C and the cases (HCVRNA≥106 copies/mL) of group A(P<0.05). Conclusion:The efficacy of the combination plot of recombinant interferon and ribavirin in the treatment of CHC is better than the INF alone. The INF dose for the cases of the high HCVRNA copies should be higher than that for the usual cases
