ObjectiveTo investigate the serum soluble urokinase-type plasminogen activator (suPAR)in patients with multiple myeloma,its relationship with the 2-year survival rate and its clinical significance in predicting the disease prognosis.MethodsEnzyme-linked immunosorbent assay was applied to determine the levels of suPAR of 40 initial diagnosed patients with MM and 30 healthy persons as healthy control group.The patients were divided into three groups:effective (13 cases),remission (19 cases) and invalid (8 cases).ResultsUsually there was suPAR expression [(233.47±83.22) pg/ml] in serum of the healthy adults.There was no statistical difference of the suPAR expression in effective group or remission group before treated [(257.60±32.47) pg/ml,(331.00±99.80) pg/ml] compated with healthy group (t =2.04,t =1.83,P ＞ 0.05),and that in the invalid group,serum levels of suPAR [(562.20±291.0) pg/ml] was statistically significant with that of the effective group and that of the healthy control group (t =3.92,t =1.93,P ＜ 0.05).Through monitoring 17 patients,the suPAR of patients before treatment [(437.65±131.43) pg/ml] was statistically significant with that of healthy control group (P ＜0.01) and effective group after treatment [(298.76±108.59) pg/ml] (P ＜0.01).Serum suPAR of more than 2-year-survival patients [(333.02±85.37) pg/nl] during initial diagnosis was not statistically difference with that of the healthy control group (t =1.81,P ＞ 0.05).Serum suPAR of less than 2-year-survival patients [(646.01±103.97) pg/ml] was statistically different with that of healthy control group (t =3.84,P ＜0.01) and that of more than 2-year-survival patient group (t =3.50,P ＜0.01).ConclusionThe suPAR value was correlated to the stability of multiple myeloma,and can be used for disease prognosis and estimation of survival time.And the high expression of suPAR was related to the adverse prognosis.

Objective To study the expression and the clinical significance of glyican-3 (GPC3)in hepatocellular carcinoma (HCC)tissues.Methods Immunohistochemical method was performed to evaluate the expression of GPC3 in 54 cases of HCC tissues,46 cases of para-carcinoma tissues,22 cases of cirrhosis tissues,12 cases of normal liver tissues,the correlation between expression levels of GPC3 and clinicopathologic factors was analyzed.Results GPC3 protein was not expressed in normal livers tissues,the levels of GPC3 (7.39±3.64)and the positive rate (81.48%)in HCC tissues were significantly higher than para-carcinoma tissues (1.15±0.99,13.04%),cirrhosis tissues (0.32±0.56,4.54%),the difference was sta-tistically significant (P <0.05);with the increase of clinical stage ofHCC,the levels of GPC3 were increased,stage Ⅲ/Ⅳ(10.05±3.59)compared with stage Ⅰ (4.31±3.41),stage Ⅱ (7.14±3.63),and the difference was statistically signifi-cant (P <0.05).The positive rate of GPC3 was also increased(stage Ⅰ 69.23%,stage Ⅱ 81.81%,stage Ⅲ/Ⅳ 89.47%) and the difference was not statistically significant (P >0.05);the positive rate in HCC tissues was independent of sex,age, serum HBsAg,alpha-fetoprotein (AFP),tumor diameter,metastasis,clinical stage (P >0.05),only related to the cirrhosis (P <0.05).The high expression rate of GPC3 in HCC tissues was correlated with AFP,tumor diameter,cirrhosis,metasta-sis,clinical stage (P <0.05).Conclusion GPC3 has important clinical significance in the diagnosis of HCC,the expression level of GPC3 associated with the progression of HCC.

Quality control of traditional Chinese medicine (TCM) has become bottlenecks of TCM industry devel-opment and TCM international recognition. To solve the retational problems, we explored the establishment of new quality control method based on efficacy and safety. Firstly, material basis of TCM efficacy was investigated deeply and systematically. Then, quality control method based on efficacy was established by using active ingre-dients as markers. We also establish detection methods based on safety, such as pesticide residues, heavy metals and harmful elements , mycotoxins .

Objective To study whether Fcα/μ receptor(Fcα/μR)can mediate complement killing of human glomerular mesangial cells.Methods Fcα/μR cDNA contained plasmid,pcDNA3.1-Fcα/μR was transfected into a human glomerular mesangial cell(NHMC).Fcα/μR expression was detected by Western blot and laser scanning eonfocal microscopy.Binding of IgM-immune complexes(IgM-IC)to the Fcα/μR on cell membrane was detected by flowcytometry and laser scanning confocal microscopy.Killing of cells by complement was shown by Trypan blue exclusion assay.Results NHMC cells transfected with Fcα/μR could bind IgM and IgM-IC.After treatment with complement,added IgM-IC,the death rate of pcDNA3.1-Fcα/μR transfected cell was significant higher than the control groups of wild type cell,pcDNA3.1 transfected cell and the pcDNA3.1-Fcα/μR transfected cell without IgM-IC.Conclusion IgM-IC can bind to the Fcα/μR expressed NHMC cells and mediate complement killing of the cells.
