OBJECTIVE:To observe clinical efficacy and safety of Mailuoning injection combined with benazepril in the treat-ment of chronic glomerulonephritis. METHODS:130 patients with chronic glomerulonephritis were randomly divided into observa-tion group and control group,with 65 cases in each group. Both groups received rountine treatment as low salt and fat diet. Control group was additionally given Benazepril tablet 10 mg,qd;observation group was additionally given Mailuoning injection 20 ml added into 5% Sodium chloride injection 250 ml,ivgtt,qd,on the basis of control group,20 days of drug withdrawal every 10 days. Both group received 4 months of treatment. Clinical efficacy of 2 groups were observed as well as the levels of BUN,UCr, SCr and 24 h urine protein quantitative (UPE) before and after the treatment. The incidence of ADR was compared between 2 groups. RESULTS:Total effective rate of observation group was 83.1%,which was significantly higher than 67.7% of control group,with statistical significance (P<0.05). There was no statistical significance in BUN,UCr,SCr and 24 h UPE between 2 groups before treatment (P>0.05);those indexes of 2 groups decreased significantly after treatment,and the observation group were lower than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Mailuoning injection combined with benazepril is effective for chronic glo-merulonephritis,and can effectively improve renal function with good safety.

Objective To probe the immunological traits of mesenchymal stem cells derived from umbilical cord Wharton's jelly (WJMSCs). Methods The diced Wharton's jelly which was from healthy fullterm birth human umbilical cord was cultured. The mesenchymal stem cells were identified with mesenchymal stem cells markers expression by flow cytometry and multiple differentiation ability. The expression of MHC- Ⅰ / Ⅱ, costimulatory molecules (CD40, CD80 and CD86) was detected with flow cytomctry, immunocytochemistry, and RT-PCR. The expression of immune inhibitors like HLA-G, IDO, and PGE2 was detected by immunocytochemistry and RT-PCR. The expression of immune-related molecules as IL-10, TGF-β, FGF and VEGF was detected with antibody microarray and western blot. Further more, to clarify the in vivo immune reaction of hWJMSCs, we fabricated the hWJMSC-scaffold constructs and implanted them into the rabbit backs. The lymphocyte infiltration and implanted cell survival observed with immunofluorescence. Results After culturinge of diced Wharton's jelly tissue, we obtained spindle-shaped cells. With differentiation medium, the cells can differentiate into osteoblasts, chongdrocytes, adipose cells and schwann cells. Expression of MHC, costimulatory molecules, and a series of immune suppressive-related molecules was found. Immune inhibitors as HLA-G, 1DO, PGE2, and immune suppressive related molecules as HGF, VEGF, TGFand IL-10 were positively expressed. But the cells did not express MHC-Ⅱ. No immune rejection was observed in vivo after implantation of hWJMSC-scaffold constructs. Conclusion It can be concluded that hWJMSCs have very low immunogenicity, which means the cells have potential to induce immune tolerance.The hWJMSCs do not provoke immune rejection in vivo.
