ObjectiveTo estimate the application of mycophenolate mofetil (MMF) and cyclophosphamide(CTX) intravenous pulse therapy on diffuse proliferative lupus nephritis (DPLN).MethodPubMed,Medline,EMBASE and CNKI were searched from the establishment of the database.Meta-analysis of 14 comparative studies on MMF and CTX in treatment of DPLN was performed,taking the remission,the relapse,the death of MMF and CTX for DPLN as primary efficacy variable,mean while taking the herpes zoster as safety evaluating indicator.ResultsMMF was better than CTX in remission rate ( P ＜ 0.05 ).There was no difference between in incidence rate of the relapse,the death and the herpes zoste MMF and CTX for DPLN ( P ＞ 0.05 ).ConclusionMMF was better than CTX on the efficacy and safety in DPLN.

Objective Mizoribine ( MZR) is a new immunosuppressant , however , little domestic research has been done on MZR for treatment of nephrotic syndrome in children .This study was to investigate curative effect and adverse reaction of MZR in the treatment of children with frequently relapsing nephrotic syndrome , using prospective controlled trials . Methods A total of 59 pa-tients with frequency relapsing nephrotic syndrome were randomly divided into two groups .29 patients of treatment group were treated with MZR +glucocorticoid , while 30 patients of control group were given Tripterygium wilfordii ( TW)+glucocorticoid treatment , and the course of treatment lasted for 12 months.24-hour urine protein, urinary N-acetyl β-glucosidase (NAG), serum albumin, serum cholesterol, serum creatinine, recurrence frequency, and average prednisone dosage were observed . Results At the end of treat-ment, Serum albumin in treatment group was higher than that in control group [(40.95 ±6.12)g/L vs (30.25 ±9.02)g/L], and Se-rum cholesterol ([5.45 ±0.82]mmol/L vs [7.53 ±2.74]mmol/L), urinary protein ([0.89 ±0.52]g/24 h vs [1.63 ±2.02]g/24 h), urinary NAG enzyme ([21.43 ±14.16]U/g· Cr vs [41.67 ±12.35]U/g· Cr) levels were lower compared with control group . There was significant difference between the two groups .In terms of mean recurrence times , no significant difference was found at 6th months of follow-up between the two groups, however, treatment group had lower recurrence rate than control group at 3rd month, 9th month, 12th month of follow-up, which was of significant difference .The average amounts of hormone of treatment group were lower than those of control group ([0.56 ±0.16] mg/kg· d vs [0.72 ± 0.34]mg/kg· d)、([0.64 ±0.35]mg/kg· d vs [0.67 ±0.52]mg/kg· d)、([0.53 ±0.41] mg/kg· d vs [0.83 ±0.37] mg/kg· d)、([0.34 ±0.15] mg/kg· d vs [0.54 ±0.26] mg/kg· d) at 3rd month, 6th month, 9th month, 12th month of follow-up, which was of significant difference . Conclusion Compared to Tripterygium wil-fordii combined with hormone therapy , MZR combined with prednisone therapy in children with recurrent NS frequency can reduce the relapse rate and dosage of corticosteroid to improve the clinical remission rate .

Objective To investigate the renoprotective effect of aspirin-triggered lipoxins(ATL)on kidney of mice with acute kidney injury(AKI).Methods Eighty-eight male specific pathogen-free(SPF)C57BL/6J mice were randomly divided into lipopolysaccharide(LPS)groups(including 2 h group,4 h group,8 h group,12 h group, 24 h group),ATL+LPS(including 2 h group,4 h group,8 h group,12 h group,24 h group)and normal control group according to random numble table,and each group had 8 mice.The mice in LPS groups were given LPS intraperitoneal injection to establish AKI animal models,while the mice in ATL+LPS groups were given ATL intraperitoneal injection 30 minutes before LPS intraperitoneal injection.The enzyme linked immunosorbent assay was used to test the serum creatinine(Scr),serum urea nitrogen(BUN),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)and urine neutrophil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),cysteine-rich protein-61 (Cyr61)and netrin-1 levels of mice.Results The kidney tissue injury scores of mice of ATL+LPS group[4 h:(22.32 ± 1.04)scores,8 h:(31.11 ± 1.86)scores,12 h:(18.22 ± 0.92)scores,24 h:(20.87 ± 3.18)scores] were lower than those of LPS group at the corresponding time points[4 h:(35.47 ± 2.27)scores,8 h:(52.28 ± 2.82) scores,12 h:(54.99 ± 4.56)scores,24 h:(53.41 ± 4.76)scores],and the differences were statistically significant(all P<0.01).The values of Scr,BUN,TNF-α and IL-1β in ATL+LPS group[Scr 8 h:(143.07 ± 5.02)μmol/L, BUN 12 h:(33.07 ± 3.52)mmol/L,TNF-α 4 h:(196.33 ± 14.181)ng/L and 8 h:(221.77 ± 10.11)ng/L,IL-1β 4 h:(50.25 ± 2.67 ng/L)]were lower than those in LPS group at the corresponding time points[Scr 8 h:(227.43 ± 11.17)μmol/L,BUN 12 h:(59.68 ± 3.84)mmol/L,TNF-α 4 h:(267.87 ± 26.48)ng/L and 8 h:(334.78 ± 21.08)ng/L,IL-1β 4 h:(89.45 ± 5.87)ng/L],and the differences were statistically significant(all P<0.01). The urine NGAL[4 h:(56.76 ± 4.01)μg/L,8 h:(65.44 ± 7.81)μg/L],KIM-1[8 h:(78.19 ± 9.48)μg/L] and netrin-1[8 h:(40.12 ± 2.01)ng/L,12 h:(36.87 ± 2.87)ng/L]of mice in ATL+LPS group were lower than those in LPS group at the corresponding time points[NGAL 4 h:(168.77 ± 10.77)μg/L,8 h:(155.33 ± 8.26) μg/L;KIM-1 8 h:(124.73 ± 13.47)μg/L;netrin-1 8 h:(89.17 ± 2.74)ng/L,12 h:(81.11 ± 3.88)ng/L],and the differences were statistically significant(all P<0.01).Conclusions ATL can treat LPS-induced AKI and play a renoprotective role in the kidney.
