Objective To clone the full length staphylococcal protein A(SPA) gene from Staphylococcus aureus (ATCC6538), and subsequently study the gene structure and antibody binding ability.Methods The full length and the functional region of the SPA gene were cloned into pHisSUMO vector respectively, and expressed in E. coli. The full length and the functional fragment of the SPA protein were detected for antibody binding ability and stability. The functional fragment of the SPA protein fused with SUMO was coupled to the CNBr-activated agarose for antibody purification from rabbit serum. Results A variant of the full length SPA gene was cloned, which has been submitted to GenBank (the accession number is EU695225). Two fusion proteins had the same antibody binding ability as the untagged SPA protein. However, the formers was more stable than the latter at the tested conditions. SUMO-SPA conjugated-agarose kept high efficiency for antibody binding. Conclusion To our knowledge, the full length SPA gene of S.aureus(ATCC6538) is a novel variant. The SUMO tag can improve the stability of the functional region of the SPA protein without damaging the antibody binding ability. This fusion protein has been used for antibody purification successfully.

Objective To investigate the effect of the eye-acupuncture therapy on serum TNF-α levels in rats with cerebral ischemia-reperfusion injury and the related mechanism. Methods Healthy SD rats were randomly divided into four groups: normal group, sham-operated control group, ischemia-reperfusion model group and eye-acupuncture group according to body weight. Sham-operated control group, ischemia-reperfusion model group and eye-acupuncture group were divided into the 3h group, the 24h group and the 72h group, a total of 10 groups (n=8). To establish the rat model of cerebral ischemia-reperfusion by suture method in ischemia-reperfusion model group and eye-acupuncture group. Eye-acupuncture was separately started immediately after reperfusion and at 30 min before sampling in the 3h eye-acupuncture group, besides, eye-acupuncture was separately taken every 12h in the 24h eye-acupuncture group and in the 72h eye-acupuncture group. The rats in normal group were not treated, those in sham-operated control group were inserted the fishing thread 1cm, and the others were identical with those in ischemia-reperfusion model group. At 3h, 24h, 72h after reperfusion, the neurophysical behaviours were accessed by ZeaLonga neurophysical impairment marks in ischemia-reperfusion model group and eye-acupuncture group. The method of ELISA was taken to detect the change of serum TNF-α levels in rats after the eye-acupuncture therapy. Results Compared with the ischemia-reperfusion model group, the neurologic impairment score of the eye-acupuncture group decreased obviously; The levels of serum TNF-αin ischemia-reperfusion model group at 3 h, 24 h, 72 h respectively were(76.803±18.325)pg/ml、(85.511±13.334)pg/ml、(86.831±9.232)pg/ml. The level of serum TNF-α in normal group was(24.304±6.511)pg/ml. The level of serum TNF-α in Sham-operated control group at 3 h, 24 h, 72 h respectively were(24.928±3.792)pg/ml,(27.533±5.362)pg/ml,(29.366±5.874)pg/ml. Ischemia-reperfusion model group compare with normal group and sham-operated control group, the difference were significant(P＜0.01). The levels of serum TNF-α in rats after the eye-acupuncture therapy at 3 h, 24 h, 72 h respectively were(40.185±3.335)pg/ml, (48.523±7.687)pg/ml, (51.611± 6.403)pg/ml. Compared with ischemia-reperfusion model group, the levels of serum TNF-α were strongly reduced(P＜0.01). Conclusion The eye-acupuncture therapy could play a role in improving cerebral ischemia-reperfusion injury evidently and the mechanism was related to its reducing serum TNF-α levels.

AIM: To observe the expressions of aquaporin 2 (AQP2) in kidney tissues and the contents of endotoxin (ET), interleukin-1 β (IL-1β), tumor necrosis factor-α (TNF-α) in serum in emphysema model rats, and to investigate the relationship between lungs and kidney in humoral metabolism. METHODS: The rats of emphysema were treated by injecting lipopolysaccharide into the trachea with cigarette smoking. Immunohistochemistry and Western blotting analysis were used to observe the expression of AQP2 in kidney tissues. RT-PCR was applied to detect the expression of AQP2 mRNA in kidney tissues. Blood sample and lung tissue were taken and the levels of ET, IL-1β and TNF-α were measured by radioimmunoassay. RESULTS: AQP2 expression in the kidney tissue in model group was greater than that in control group, and the expression of AQP2 mRNA showed the same results (P<0.01). ET, IL-1β and TNF-α levels in serum and lung tissue in model group were markedly higher than those in control group (P<0.01). CONCLUSION: In the emphysema model rats, AQP2 expression is up-regulated in the kidney tissue. The mechanism of emphysema may be related to increasing the levels of ET, IL-1β and TNF-α in the serum and lung tissue obviously.

The aim of this project is to establish a fibroblast growth factor-21 (FGF-21) signaling pathway targeted cell model, for screening a class of FGF-21 receptor agonists as anti-diabetic candidates. FGF-21 requires beta klotho transmembrane proteins as co-receptor for the activation of tyrosine kinase FGF receptor (FGFR) signaling, thereby activating a series of intracellular signaling pathways and regulating gene transcription for glucose metabolism. Firstly a recombinant plasmid expressing co-receptor beta klotho and EGFP reporter genes was constructed. After introducing the recombinant plasmid into package cells, the cell culture supernatant was used to infect 3T3-L1 cells, which were then screened for stably expressing beta klotho gene. Administration of FGF-21 increased the expression of GLUT1 and stimulated GLUT1-mediated glucose uptake. This novel cell model can be conveniently used in high-throughput drug screening of FGF-21 or FGF-21 analogues.
