Objective To investigate the effects and underlying mechanism of calcitriol on ameliorating podocytes impairment in DN rats.Methods SD rats were randomly divided into four groups:normal control (NC) group,calcitriol treatment (VD) group:calcitriol 0.1μg· kg--1 d-1,diabetic nephropathy (DN) group:streptozocin (STZ) 58 mg/kg,DN treated with calcitriol (DN + VD) group:calcitriol 0.1 μg · kg-1 · d-1 + STZ 58 mg/kg.Rats were sacrificed at the end of 18 weeks.Results Compared with the DN group,the DN + VD group exhibited significantly lower proteinuria by 36%,improved renal histology at the end of the experiment (P < 0.05),and similar levels of blood glucose,serum urea nitrogen as well as body weight (P > 0.05).There were no significant differences in the serum concentrations of creatinine,calcium and phosphorus among the four groups (P > 0.05).In DN group,the expressions of nephrin,podocin,VDR,PI3K-p85 and p-Akt were significantly decreased and the expression of desmin was increased compared to NC group.Calcitriol treatment could attenuate the above changes.Additionally,a positive correlation was observed between the expressions of nephrin and VDR (r=0.776,P < 0.05).Likewise,the expression of nephrin was positively correlated with either PI3K -p85 or p-Akt (r=-0.736,r=0.855,all P < 0.05).Conclusion Calcitriol can ameliorate podocytes injury in DN rats,which might be related with the further up-regulation of PI3K/p-Akt signaling pathway.

Objective To investigate the effect of 1,25(OH)2D3 on high glucose induced macrophage activation and its underlying signal transduction mechanism.Methods RAW 264.7 cells were used to perform cell culture,the activity of intracellular iNOS was measured.VDR siRNA and PPARγ antagonist pre-treatment with macrophages were done before using 10-8 mol/L1,25(OH)2D3 to intervene high glucose pre-incubated macrophages.M1 markers including iNOS,TNF-α,IL-12,M2 markers including MR,Arg-1,IL-10 and nuclear receptors VDR and PPARγ were separately examined.Results The iNOS activity was increased in a glucose-dose and time dependent manner.Particularly,25 mmol/L glucose at 24 h gave the maximum response.After being treated with 25 mmol/L glucose for 24 h,not only inflammatory cytokines of TNF-α,IL-12 in the supernatant were increased,but quantitative real-time PCR and Western blotting analysis showed iNOS was also up-regulated (P < 0.05).However,M2 markers,i.e.MR and Arg-l were significantly decreased (P < 0.05).When in the presence of 1,25(OH),D3,the trends were reversed:the markers of M1,including TNF-α,IL-12 and iNOS were obviously reduced (P < 0.05),while M2 markers,IL-10,Arg-1 and MR were increased (P < 0.05).In addition,VDR and PPARγ were also increased (P < 0.05).However,the above effects of 1,25 (OH)2D3 were abolished when further inhibited the expression of VDR and PPARγby VDR siRNA and PPARγ antagonist.Besides,accompanied by VDR,PPARγwas also decreased upon the treatment with VDR siRNA (P < 0.05).Conclusion 1,25(OH)2D3 can promote high glucose induced classically activated macrophages (M1) converting to alternatively activated macrophages (M2) and this is achieved through VDR-PPARγ pathway.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.
