Objective To establish a HPLC-ELSD method for determining the content of astragaloside Ⅳ in Qingshen Jianfei Tablets. Methods Stationary phase was C_(18) column (4.6 mm?250 mm, 5 ?m), mobile phase was acetonitrice-water (35 : 65). The evaporation temperature was 120 ℃, the pulverization temperatire was 80 ℃, the flow rate was 1.6 mL/min and column temperature was 35 ℃. Results The standard curve was linear within the range of 1.03～8.24 ?g, r=0.9999. The average recovery was 99.35% with RSD = 1.36% (n = 6). Conclusion The established method is simple and accurate, with good reproducibility and high precision, and suitable for the determination of astragaloside Ⅳ in Qingshen Jianfei Tablets.

Objective To investigate the effect of chemotherapy on ovarian function in young patients with malignant germ cell tumors of the ovary after conservative surgery.Methods 15 patients (11～29 years old) with ovarian malignant germ cell tumors were treated by ovarectomy and the following chemotherapy.Their menstruation and serum follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2) levels and basal antral follicle(F0) numbers were observed from the duration of chemotherapy to one year after chemotherapy.The serum levels of FSH,LH,E2 and basal antral follicle numbers between the chemotherapy-related amenorrhea(CRA) patients and the patients with benign tumors of ovary who underwent unilateral adnexa removed at the same period(control group,n=10) were compared.Results Oligomenstruation occurred in 13 of 15 cases undergoing chemotherapy after conservative surgery(86.7%),in whom CRA occurred in 10 cases(66.7%) at the duration of 4-6 cycle chemotherapy appearing significantly rising serum level of FSH,LH and declining serum E2 level and F0 numbers.There was a significantly positive correlation between the frequency of amenorrhea and the duration of chemotherapy(r=1.000,P=0.01).Generally menstruation resumed around 2～3 months after chemotherapy.Ahhough the serum levels of sexual hormone seemed to be normal at half a year after chemotherapy in CRA patients,the serum FSH(8.30±1.46 mU/ml) and E2(80.50±7.86 ng/L) level were significantly increased as compared with that of the control group and the reverse was found in Fo numbers(3.80±1.04) (t Fo,FsH,E2=7.660,5.277,7.225;P F0,FSH,E2<0.001,<0.001,<0.001).One year after chemotherapy,serum hormone level and the ovary reserve function of the CRA patient came to be normal[FSH=(5.59±0.52)mU/ml,LH=(5.25±0.84)mU/ml,E2=(56.50±5.13)ng/L,Fo=(6.50±1.08)] and that of control group [FSH=(5.43±0.35)mU/ml,LH=(5.17±0.48)mU/ml,E2=(58.10±3.73)ng/L,F0=(6.60±0.97)](t=1.177,0.694,0.505,0.740;P>0.05,>0.05,>0.05,P>0.05).Conclusions Ovarian function impairment may occur in young patients in adolescence and sexual maturity period with ovarian malignant germ cell tumors who were treated by conservative surgery followed by chemotherapy.Although the CRA is reversible,the recovery of menstruation does not meail the recovery of ovarian funetion.because the ovarian impairment may continue to a duration of half a year after chemotherapy.The drug which can safeguard ovariall function should be considered during chemotherapy.

Objective To explore the relationship between ULI43 sequence variability and clini-cal disease. Methods UL143 from samples obtained from suspected congenitally human cytomegalovirus (HCMV) infected symptomatic infants were PCR amplified and sequenced. Results There were not too much sequence variability of UL143 compared with Toledo. But no one was completely identical to Toledo, and all UL143 ORFs were shorter than Toledo for frame-shift. Conclusion HCMV-UL143 existed in moat of low passage isolates and sequences were variable. No obvious linkage was observed between UL143 poly-morphisms and outcome of suspected congenital HCMV infection.

Objective To explore the effect of astragalus injection with heparin in treatment of children with nephrotic syndrome(NS) whose blood was high coagulable.Methods Seventy-two children suffering from NS, whose blood was high coagulable,were randomly divi-ded into 2 groups. The suffering children of 2 groups were given diuretic and anti-infective and hypotenive drugs, simultaneously taking prednisone 2 mg/( kg?d). In addition, the suffering children of therapeutic group was given astragalus injection 20 mL and heparin 100 IU/kg which were added in the glucose injection 200 mL absorbed by intravenous drop.They had blood test since they had taken the medicine once a day and maintained 2-4 weeks′ time.Results The suffering children′s PLT,febrinogen(Fbg) and prothrombin time(PT) of therapeutic group were all lowered down to normal quantity in 10 days but those of contrastive group in 2 weeks or more. The time of urinary protein′s vani-shing of the therapeutic group averages out to (8.9?4.1) d;but contrastive group became normal after 2 weeks and urinary albumen disa-ppeared in (12.8?6.2) d.Conclusions The astragalus injection with heparin is significant to shortening the course of treatment and redu-cing the relapse and preventing from thrombosis in the treatment of NS of suffering children whose blood is high coagulable.The treatment of anti-coagulation can be one of conventional plans.
