Objective To observe the efficacy and adverse reaction of the test drug hepatitis B immunoglobin on the post market.Method Employed by the methods of multiple center's clinical trials and using the recommended dosage of hepatitis B immunoglobulin for intravenous administration,the clinical efficacy of either prevention or treatment for hepatitis B recurrence and drug related adverse reactions were observed.This consisted of 22.1 months,13 hospitals,and 525 patients with hepatitis B related liver transplantation.Result The results showed a contrasting probability of adverse reactions for different doses among the observation period.Within 6 months postoperatively with a greater or equal to recommended drug dose,the infection rate was less than 4％.In contrast,the infection rate was greater than 12％ in the group with less than the recommended drug dose.Conclusion There was an obvious dose effect relationship,and the drug safety and recommended treatment rationality were verified.

Objective To explore the influence of hemodialysis(HD) and henodiafiltation on serum ?_2-microglobulin(?_2-MG) of children with acute renal failure and contrast research on declining rate of serum ?_2-MG before and after(children′s) HD and HDF.(Met-)hods By Branc Dialog HD machine of double-pump,HDF for 18 times and HD for 20 times were given to children with acute renal(fai-)lure.The serum ?_2-MG were observed before and after HD and HDF.Results A great difference was observed in level of serum ?_2-MG between before and after HD and HDF.In HDF group,there was significant difference in level of serum ?_2-MG before and after HDF(P

Objective To evaluate the protective effects of Sipunculus nudus preparation(SNP) on mice irradiated by 60Co.Methods The mice were divided into control group,model group and 0.5,1.0,and 2.0g?kg-1?d-1 SNP groups.SNP was administrated by intra-gastric infusion with the volume of 0.4mL per 20g.In the fifteenth day,the model group and the treated groups were irradiated by ?-ray of 60Co(0.83Gy/h) with the dose of 5 Gy.Peripheral blood WBC,RBC,PLT,the spleen(SI) and thymus index(TI),the BMNC,SOD and MDA in serum,testicle index,germ cells were detected.Results Comparing with the model group,TI,SI and peripheral blood WBC,RBC and BMNCs were higher.The activities of SOD in serum were increased,while MDA decreased.Testicle index and germ cells were increased,and germ abnomality rate was decreased in SNP groups.Conclusion SNP has protective effects on mice irradiatied by 60Co.

Objective To discuss the application of the hemodialysis and filtration(HDF) in children with acute renal failure(ARF).Methods By Branc Dialog hemodialysis machine of double-pump,HDF for 19 times and hemodialysis(HD) for 21 times were given to the children with ARF.The serum blood urea nitrogen(BUN),creatinine(Cr),uric acid(UA),?_2 microglobulin(?_2-MG) and the rate of the heart,blood pressure,temperature were observed before and after HD and HDF.Results The clearance rates of BUN,Cr,UA,(?_2-)MG of HDF were markedly higher than those of HD(P

OBJECTIVETo study the expression of nNOS and ultrastructural changes in the penile tissue of rats with prolactinoma-induced erectile dysfunction (ED).

METHODSWe established the model of prolactinoma in 20 male Westar rats by peritoneal injection of diethylstilbestrol (DES) and treated the control rats with normal saline (n = 10) or sterilized arachis oil (n = 10). After 8 weeks, we performed the apomorphine test and measured the weight of the pituitary gland and the levels of serum prolactin (PRL) and testosterone (T) to confirm the successful construction of the prolactinoma-induced ED model. Then we determined the expression of nNOS in the penile tissue by immunohistochemistry and examined the ultrastructural changes of the penile cavernosum under the transmission electron microscope.

RESULTSThe prolactinoma-induced ED model was successfully established in 15 rats. The weight of the pituitary gland was significantly increased in the rats treated with DES as compared with the normal saline and sterilized arachis oil controls ([46.7 ± 15.5] vs [11.7 ± 2.4] and [12.4 ± 2.3] mg, both P < 0.05). The level of serum PRL was markedly higher while that of T remarkably lower in the former than in the latter two groups ([1,744.9 ± 304.5] vs [11.5 ± 2.4] and [10.6 ± 1.9] ng/ml, both P < 0.0l; [1.54 ± 0.46] vs [3.11 ± 1.08] and [3.04 ± 1.11] ng/ml, both P < 0.05). The rate of penile erection was significantly reduced in the prolactinoma-induced ED model rats in comparison with the normal saline and arachis oil controls (16.7% vs 100% and 87.5%, both P < 0.05), and so was the expression of nNOS in the penile tissue (0.024 ± 0.011 vs 0.066 ± 0.019 and 0.058 ± 0.021, both P < 0.05). Transmission electron microscopy manifested significant ultrastructural changes in the endothelial and smooth muscle cells of the cavernous tissue in the prolactinoma-induced ED models.

CONCLUSIONThe ultrastructural changes of the penile cavernous tissue and the reduced expression of nNOS in penile tissue may be the most important mechanisms of prolactinoma-induced ED in rats.

OBJECTIVETo investigate the characteristic and influential factors of the degradation of residual pesticides and alkaloids in Radix Sophorae Flavescentis by H2O2.

METHODThe spiked samples were treated in H2O2 in different reaction time, concentration and pH value. The pesticide residuals were determined by GC-MS, and the contents of alkaloids were determined by HPLC.

RESULTH2O2 had highly activity in degrading organophosphorus and pyrethroid, but had less activity to organochlorines. The degradation processes of organophosphorus and pyrethroid followed first-order kinetics equations, and were influenced by the pH value, the concentration of H2O2 and reaction time. The contents of alkaloids in Radix Sophorae Flavescentis changed not obviously after treatment with 3 mL x L(-1) H2O2 less than 6 hours under neutral condition.

CONCLUSIONH2O2 is a useful reagent for the degradation of organophosphorus and pyrethroid in crude drug.

AIMTo screen swimming-fatigue related genes in mice and lay theoretic basis for researching the molecular mechanism of fatigue.

METHODS30 male BALB/c mice (20 +/- 2g) were divided into control group, dipping in water group and swimming-fatigue group respectively. After fatigue for swimming in swimming-fatigue group, with control group and dipping in water group, liver tissues in mice were collected. With improved silver staining mRNA differential display method, the differentially expressed genes in mice livers were screened and evaluated by reversed Northern blot. The positive segments were analyzed homology by BLAST.

RESULTS7 of DD-ESTs were gained. Two of them only expressed in swimming-fatigue group, two down-regulated expressed, and three up-regulated. One of them was a novel gene and was accepted by GenBank, AY615302.

CONCLUSIONSeven DD-ESTs in swimming-fatigue mice were gained by silver staining mRNA differential display method.
