A potentiometric immunoelectrode with non-labeled anticancer antigen CA 15-3 antibody used for determinating CA15-3 was reported. firstly, the anti-CA15-3 antibody was immobilized on the surface of polyvinyl chloride-bovine serum albumin membrane, which was activated previously. Secondly, CA15-3 was added on the surface of the antibody membrane to form the antigen-antibody complex. Lastly, the complex membrane was used to assemble an immunoelectrode with an Ag-AgCl inner electrode. The potential of the complex membrane was measured with a pH meter. The response was linear over the range of 15～240　U／mL with a correlation coefficient of 0.9998. Other common antigens in human serum did not interfere with the determination of CA15-3. The mechanism of potential response was explored.

OBJECTIVE: To explore whether there are beta-amyloid protein (Abeta) binding elements in heart-beneficial recipe (HBR, a compound traditional Chinese herbal medicine), which can ameliorate the cytotoxicity of Abeta. METHODS: The extract of HBR and Abeta(1-40) were co-precipitated, and the Abeta(1-40) in pellets was detected by immunoblotting. Affi-gel-Abeta(1-40) was constructed, and Affi-gel-Abeta(1-40) affinity elements from the extract of HBR were analyzed by high-performance liquid chromatography (HPLC). The assay of lactic dehydrogenase (LDH) release from the primary cultured rat cortex neurons was used to evaluate the cytotoxicity of Abeta(1-42), and the protection effects of the HBR serum and the Affi-gel-Abeta(1-40) treated HBR serum. RESULTS: Immunoblotting examination showed Abeta(1-40) could be co-precipitated with components of HBR following co-incubation, and the amount of Abeta(1-40) within pellets decreased when the HBR extract was diluted. Abeta(1-40) affinity elements from the extract of HBR, eluted from Affi-gel-Abeta(1-40) by glycine solution (pH=2.5), could be detected by HPLC-fluorescent detector system. The analysis of LDH release showed that exposure of neurons to 5 micromol/L Abeta(1-42) for 48 h caused a significant increase of LDH release in either a serum free or 10% serum contained culture condition (P<0.01). The rat HBR serum was able to suppress Abeta(1-42) induced LDH release (P<0.05), whereas Affi-gel-Abeta(1-40) treated HBR serum still maintained the ability to attenuate Abeta(1-42) induced LDH release although the effect was somewhat decreased compared with Affi-gel treated HBR serum. CONCLUSION: There are Abeta affinity components in HBR, which could not increase the Abeta cytotoxicity, but might be able to inhibit the cytotoxicity of Abeta. The results implied that the exploration of Abeta affinity elements from Chinese medicinal recipe which is effective for Alzheimer disease, might be an important direction in Alzheimer disease therapeutic research area.

Objective To clone and express bradyzoite antigen 1(BAG1) gene of T. gondii,and analyze the immunoreactivity of the recombinant product. Methods The differentiation of T. gondii RH strain tachyzoites into bradyzoites was induced in vitro,and the coding sequence of BAG1 was amplified from bradyzoites by RT-PCR. The PCR product was analyzed by sequencing. The BAG1 coding sequence was further subcloned into the plasmid pET32a(+). The plasmid pET32a(+)-BAG1 was then transformed into BL21(DE3) to express after IPTG induction. The expression product was purified with Ni-NTA agarose and the purified BAG1 was further analyzed by Western blotting and ELISA. Results BAG1 cDNA was amplified from bradyzoites. After IPTG induction,BAG1 was expressed in a fusional form in E. coli. Western blotting showed that the purified recombinant protein could be specifically recognized by sera from mice chronically infected by T. gondii B36 strain. ELISA showed that the positive rate of T. gondii IgG antibodies of 350 human sera detected by the recombinant BAG1(17.4%) was higher than by recombinant SAG1 (12.6%)(P

Objective To investigate the effect of noninvasive ventilator therapy on serum C-reactive protein (CRP), endothelin-1 (ET-1) and tumor necrosis factor-α (TNF-α) levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and its clinical significance. Methods One hundred cases of moder-ate and severe OSAHS patients were selected by the method of parallel opening. All of the patients were given health education requirement , quitting smoking and wine , low fat diet and exercise to lose weight and other con-ventional treatment. The patients were randomly divided into the treatment group of 42 cases with noninvasive ventilator treatment , 44 cases treated with conventional treatment , to observe the changes of serum CRP , ET-1 and TNF-α levels and PSG parameters after 12 weeks in two groups. Results Apnea hypopnea index (AHI), oxygen desaturation index (ODI), the lowest oxygen saturation (LSpO2), and the average oxygen saturation MSpO2 in OSAHS patients were significantly improved after treatment (P < 0.01), but the degree of improvement in the two groups after treatment was significantly higher than the control group (P < 0.01). Plasma CRP, ET-1 and TNF-α levels in the two groups after treatment were lower than before treatment (P < 0.05 or P < 0.01), but the treatment group was significantly higher than that of the control group ( P < 0 . 05 or P < 0 . 01 ) . Conclusion Noninvasive ventilator therapy in improving the OSAHS monitoring data of patients with PSG can effectively reduce the serum CRP, TNF-α, ET-1 level, reduce the body′s inflammatory reaction.
