The viscosity of mucopolysaccharides in Holothuria scabra Jaeger was related to temperature, time, concentration of mucopolysaccharides and H 2O 2 during the decoloration, which was found through the experiment, in that the rise of temperature, elongation of time, decrease of concentration of Mucopolysaccharides and increase of that of H 2O 2 all lead to the decrease of the viscosity. Within a certain limit, the activity of mucopolysaccharides rises with the viscosity decrease in the experiment of acute cerebral ischemia in mice. So that it is important controlling the craft in the mucopolysaccharides production.

Suerm monoamine oxidasa isoenzymes (MAOi) were determined in 105 cases of liver disea ses and 49 normal controls.MAOi were separated into 3 bands (I. Ⅱ.Ⅲ) by polyacrylamide gel elcctrophoresis. The results revealed that MAOi Ⅲ% was increased in chronic liver diseases, especially in liver cirrhosis. Our findings suggest that serum MAOi determination is more sensitive than serum albumin, MAO, ChE, and ADA determinationsin in the early diagnosis of liver cirrhosis

OBJECTIVE: To establish a RP - HPLC method for simultaneous determination of the concentrations of phe-nobarbital, phenytoin and carbamazepine in serum.METHODS: Phenobarbital, phenytoin and carbamazepine were extracted from serum with CH2Cl2 and analysed using C18 column with mobile phase consisting of methanol - water(57 : 43); the column temperature was 30℃ ; the detecting wavelength was 254nm and the flow rate was 0.8ml/ min.RESULTS: The calibrating curves of phanobarbital, phenytoin and carbamazepine were linear in the ranges of 2.5 - 40, 2.5-40 and 1.25-20?g/ ml respectively .The within- day and between- day RSDs were less than 10% (n = 5) .CONCLUSION : This method is simple and reliable and suitable for phenobarbital,phanytoin and carbamazepine monitoring.

OBJECTIVE Through detecting hepatitis B virus markers and hepatitis B virus DNA,to probe into the significance of HBV-DNA detection in HBsAg negative blood donors for blood transfusion safety.METHODS ELISA was used for detecting hepatitis B virus markers,and real-time fluorescent quantitative PCR assay was introduced for measuring HBV-DNA.RESULTS Totally 1 698 samples from HBsAg negative blood donors were examined,the positive rate of HBV-DNA was 2.71%.The rate of the HBsAb positive and HBcAb positive group,the HBsAb positive,HBeAb positive and HBcAb positive group,the HBcAb positive group,the HBeAb positive and HBcAb positive group,the HBsAb positive group and the all hepatitis B virus markers negative group were 5.71%,3.60%,6.60%,2.77%,38.48% and 46.94%,respectively.The positive rate of HBV-DNA in these groups were 7.22%,8.20%,4.46%,8.51%,1.21% and 2.26%,respectively.CONCLUSIONS It′s very important for blood transfusion safety to detect HBV-DNA in HBsAg negative blood donors.The more economic,reasonable and effective detecting method should be developed for blood transfusion safety.

Parkinson’s disease is resulted from the progressive degeneration and from the loss of dopaminergic neurons in Substantia Nigra. Current researches focuson the optimum conditions in vivo and in vitro associating the differentiation as well as survival of dopaminergic neurons,in order to get sufficient dopaminergic neurons for cell-replacement therapy in Parkinson’s disease. This paper reviewed influential factors of neural stem cells differentiate into dopaminergic neurons in vivo and in vitro.

The third generation of aromatase inhibitors (AI) play an important role in the adjuvant treatment of hormonal positive postmenopausal breast cancer. Compared with tamoxifen, either upfront or sequential using of Al can both significantly improve the outcome of breast cancer patients. However, there is a continuous debate of sequence or upfront usage of Al in clinical applications. With the publication result of BIG 1-98 clinical trial and interpretation of the data, we can further recognize and optimize the usage of Al in breast cancer treatment.

Breast cancer ranks among the most prevalent malignancies in women. Specific aspects of both breast cancer cells and the bone microenvironment contribute to the development of bone metastases. Breast cancers express chemokine receptors, integrins, cadherins, and bone-resorbing and bone-forming factors that contribute to the successful and preferential spread of tumor from breast to bone. Bone is rich in growth factors and cell types that make it a favorable environment for breast cancer cell growth. Once breast cancer cells enter the bone, breast cancer cells can secrete factors that act on bone cells and other cells within the bone, causing them to secrete factors that act on adjacent cancer cells. The steps in the metastatic cascade and the vicious cycle within bone offer unique targets for adjuvant treatments to treat and cure bone metastasis.

Gastrointestinal stromal tumor(GIST) ,a kind of rare tumor,takes 1%～3% of all tumors in digestive tract,but are the most common in mesenehymal neoplasm.At present,the primal treatment of GIST is surgical operation,standard and rationality of surgery is the significant fatter that affects its curative effect.While imatinib is the main therapeutic tool for GIST that can' t benn resected or recurrence after operation.There is no definite circumscription between optimum and malignancy,there are many factors that influence the prognosis of GIST.We commonly apply Fletcher grading to evaluate the risk of GIST.

Objective To investigate the effect of isoflurane preconditioning on Bcl-2 and Bax mRNA expression and the signaling pathway of nitric oxide against brain ischemia-reperfusion(I/R).Methods Seventy-five male gerbils were randomly divided into 5 groups(n=15):SHAM,I/R,ISO,AG+ISO and AG group.Global cerebral I/R was produced by occlusion of bilateral common carotid arteries for 5 minutes and confirmed by isoelectric potential on EEG.In ISO group,the animals inhaled 1.2%-1.5% isoflurane for 30 minutes followed by 30 minutes wash-out period before I/R.In AG+ISO group,30 minutes after aminoguanidine,200 mg/kg i.p.isoflurane was inhaled as ISO group,and aminoguanidine was injected 30 min before I/R in AG group.After 24 hours,the forebrains were collected,and the expression of Bcl-2 and Bax mRNA was determined by reverse transcriptase polymerase chain reaction.Results Bcl-2 mRNA expression in ISO group(1.22±0.12) was significantly higher than that in sham(0.83±0.16),I/R(0.83±0.11) and AG+ISO group(0.82±0.12)(P<0.05).Bax mRNA expression in I/R and AG group was significantly higher than that in sham group(P<0.05),and the expression in ISO group was higher than that in AG+ISO group.Conclusion Nitric oxide is involved in the signaling pathway of isoflurane preconditioning and has the protection effect on gerbil brain against I/R.
