After DNA sequencing, it was inserted into pGEX-2T between the sites of EcoR Ⅰ and Sma Ⅰ, then recombinant plasmid p2T-ICA69 was constructed and introduced into E.coli. The GST-ICA69 fusion protein was expressed by the induction of IPTG. The recombinant ICA69 proteins were used to detect the antibodies against hICA69 in 100 healthy subjects and type Ⅰ diabetic serum by the use of indirect ELISA. The sequence analysis showed that the amplified fragments contained 1449 bp, encoded 483 amino acids, and had been correctly inserted into pGEX-2T vector. The recombinant proteins expressed in the prokaryotic cells had immunogenicity and could be used to detect antibodies against ICA69 in type Ⅰ diabetic serum. Finally it can be concluded in this paper that the expression products obtained by the method of gene engineering are recombinant ICA69 antigen and may be used to improve the forecast rate and the diagnostic rate of type Ⅰ diabetes in combination with other tests.展开更多
The Effects of electroacupuncture (EA) at Weiwanxiashu (EX-B3) and Zusanli (ST 36) points on blood glucose (BG) and plasma pancreatic glucagon (PG) contents were dynamically observed in diabetic rabbits induced by All...The Effects of electroacupuncture (EA) at Weiwanxiashu (EX-B3) and Zusanli (ST 36) points on blood glucose (BG) and plasma pancreatic glucagon (PG) contents were dynamically observed in diabetic rabbits induced by Alloxan. It is found that acupuncture at Weiwanxiashu point can significantly lower the BG content and inhibit release of PG; no significant changes in BG and PG are found when acupuncture is given at Zusanli (ST 36) point alone, however BG and PG contents decrease more obviously when acupuncture employed at both Zusanli and Weiwanxiashu, suggesting that Zusanli has a marked synergetic action with Weiwanxiashu.展开更多

Articles were assessed independently by two reviewers. Review Manager 5.1 was used fordata analysis.RESULTS: Fourteen randomized controlled experiments were included. Meta-analysis demonstrated that blood sugar levels and kidney weight to body weight ratios in the model group were higher than those in the normal group, and the curcumin group had significantly lower mesangial area to glomerular area ratios compared with the model group, and also lower levels of urinary protein,blood urea nitrogen and serum creatinine.CONCLUSION: Curcumin shows protective effects on the kidneys of rats/mice with diabetes.展开更多
