OBJECTIVETo investigate the effect of Qufeng Tongluo Recipe (QTR) on the expression of desmin and CD2-associated protein (CD2AP) in adriamycin-induced nephropathy rats.
METHODSThe adriamycin-induced nephropathy rat model was induced by a disposable intravenous injection of adriamycin. The model was successfully established after 3 weeks. Rats were then randomly divided into the blank control group (Group A, n =12), the model control group (Group B, n = 8), the small, medium, large dose QTR group (Group C, n = 8; Group D, n = 8; Group E, n = 8), and the positive control group (Group F, n = 8). From the fourth week normal saline was given to rats in Group A and Group B, QTR 1.0 g/mL, 2.1 g/mL, and 4.2 g/mL was respectively administered to those in Group C, D, and E. Prednisone 25 mg/kg was given to rats in Group F. All medication was performed by gastrogavage at 10 mL/kg, once daily, for 28 successive days. 24-h urinary protein excretion and sera biochemical indices were determined during medication. At the end of the experiment, ultrastructure was observed, mRNA expression of desmin, mRNA and protein of CD2AP were detected by Real-time PCR and Western blot.
RESULTS(1) Compared with Group B, 24-h urinary protein excretion significantly decreased in Group C, D, E, and F (P < 0.05). (2) Compared with Group B, Alb in Group C, D, and E increased (P < 0.05) and TC significantly decreased (P < 0.05). TG significantly increased in Group F (P < 0.05). (3) Results of electron microscope showed, compared with Group B, the morphology of foot cells was improved to various degrees in Groups D, E, and F, especially the foot process structure and the number of foot processes were significantly improved, which was more obviously shown in Group D and Group E. (4) mRNA expression of desmin, mRNA and protein of CD2AP increased in adriamycin-induced nephropathy rats (P < 0.05). After intervention, when compared with Group B, mRNA expression of desmin and CD2AP were significantly lower in Group C, D, E, and F (P < 0.05). (5) Compared with Group A, expression of desmin and CD2AP significantly increased (P < 0.05). Compared with Group B, the expression of desmin protein were obviously lower in Group C, D, E, and F, and the protein expression of desmin obviously decreased in Group D, E, and F (P < 0.05). The protein expression of desmin and CD2AP gradually decreased in Group C, D, and E (P < 0.05). Compared with Group F, the expression of CD2AP protein obviously increased in Group C and D (P < 0.05); the expression of CD2AP protein obviously decreased in Group E (P < 0.05); the expression of desmin protein was higher in Group C, D, and E (P < 0.05).
CONCLUSIONQTR's therapeutic effect on adriamycin-induced nephropathy rats might be achieved through altered expression of desmin and CD2AP.

AIM: To study the effect of ginkgolide B on high glucose-induced human lens epithelial cell (HLEC) apoptosis.
METHODS: The high glucose-induced HLEC model was established. Different concentrations of ginkgolide B were intervened. Cell viability was assayed by MTT assay, morphology of cell apoptosis was observed by hochest33258 staining. Cell ultrastructural changes were detected by transmission electron microscopy. Expressions of apoptosis - related factors caspses - 3 and caspase-9 were tested by colorimetric detection.
RESULTS: High glucose inhibited the activity of HLECs, induced apoptosis reaction of HLECs, caused high expression of apoptosis factors in cells; while ginkgolide B inhibited the decrease of cell viability induced by high glucose, decreased the HLEC apoptosis and reduced the expression of apoptosis factors Caspase-3 and Caspase-9.CONCLUSION: Ginkgolide B may inhibit the expression of caspses-3 and caspase-9 then effectively inhibited high glucose-induced apoptosis in HLECs.

Binding activity and biologic effect of a novel alpha-melanocyte-stimulating hormone analogue were tested on cells transiently expressing the human melanocortin-1 (MC1), MC3, MC4, and MC5 receptors. The human MC1 and MC5 receptor genes were cloned into the expression vector pcDNA3. 1/ myc-his(-) B. The vectors were transferred to HEK-293 cells by the calcium phosphate method. Stable receptor populations were generated using G418 selection (900 microg x mL(-1)) for subsequent bioassay analysis. K(i) values of the novel alpha-MSH analogue for MC1, MC3, MC4, and MC5 receptors were obtained in competition with [125I]-NDP-MSH for binding studies. The cyclic AMP level was tested by using [3H]-cyclic AMP kit. It is showed that K(i) values of the novel alpha-MSH analogue for MC1, MC3, MC4, and MC5 receptors were (0.159 +/- 0.040), (35.430 +/- 6.743), (19.293 +/- 2.780) and (2.230 +/- 0.670) nmol L(-1), respectively. Its EC50 values for MC1, MC3, MC4, and MC5 receptors were (0.45 +/- 0.07), (7.80 +/- 0.65), (2.55 +/- 0.23) and (0.33 +/- 0.09) nmol L(-1), respectively. In these tests, the novel alpha-MSH analogue is a MC1R and MC5R selective agonist.
