Objective To discuss the effects of extract of Ginkgo BilobaLeaves(EGb) on expression of cytokine of renal interstitial fibrosis induced by transforming growth factor-?1 (TGF-?1) and extracellular matrix. Methods Cultured human kidney cells(HKC) were divided into three groups: control group,TGF-?1(8 ng/mL) group,and TGF-?1(8 ng/mL) added EGb(25,50,100,150 mg/L)group.After 72 h,expression of ?-SMA was detected by cell immunochemistry ABC,and collagen type I by Real-time PCR and Western blotting. Results Treated with TGF-?1(8 ng/mL) for 72 h,expression of ?-SMA and collagen type Ⅰ were up-regulated markedly compared with control group.Treated with EGb(25,50,100,150 mg/L)and TGF-?1(8 ng/mL)concomitantly for 72 h,expression of ?-SMA and collagen typeⅠ were down-regulated in dosage dependent manner compared with TGF-?1 group. Conclusion EGb can inhibit expression of ?-SMA and collagen type I in HKC induced by TGF-?1,and the possible mechanism might be related to the inhibition of EGb on renal tubular epithelial-myofibroblast transdifferentiation.

Objective To investigate clinical characteristics of refractory systemic juvenile idiopathic arthritis(JIA)and the efficiency of glucocorticoid in therapy on this kind of disease.Methods Thirty-nine children with systemic JIA were divided into low dose group 0.5-1.0 mg/(kg?d)and high dose group 1.0-1.5 mg/(kg?d).And the efficiency was observed by change of active index after 10 and 20 days.Results The effective power was 58.8% and 72.7% after 10 days,respectively.After 20 days,the power was 76.5% and 90.9%,respectively.The power in high dose group was significantly higher than that in low dose group.It had no difference in statistical analysis for efficiency of 2 kind of glucocorticoid dosage to control fever,but it had obvious difference to control arthralgia,arthrocele,erythrocyte sedimentation rate(ESR),C-reactive protein(CRP).Conclusion Glucocorticoid therapy is very effective to control the activity of disease in patients with systemic JIA.

OBJECTIVETo explore the effect of peimine on excision repair cross-complementation 1 (ERCC1) mRNA and lung resistant protein (LRP) expressions in A549/cisplatin (DDP) multidrug resistance (MDR) cell line.

METHODSLung cancer A549/DDP cells were cultured in vitro.Cells at logarithmic growth phase were divided into 4 groups, i.e., the blank control group, the DDP group, the ligustrazine group (DDP+ligustrazine), the peimine group (DDP + peimine). After 48-h drug action, ERCC1 mRNA expression was detected by RT-PCR and LRP expression detected by cell immunofluorescence.

RESULTSThere was no statistical difference in expression levels of ERCC1 mRNA and LRP between the DDP group and the blank control group (P > 0.05). Compared with the DDP group, expression levels of ERCC1 mRNA and LRP obviously decreased in the ligustrazine group and the peimine group (P < 0.05). They were obviously lower in the peimine group than in the ligustrazine group (P < 0.05).

CONCLUSIONSPeimine could reverse MDR of A549/DDP cell line. Its mechanism might be associated with down-regulating ERCC1 mRNA and LRP expression levels.

OBJECTIVETo investigate the accumulation of advanced glycation end products (AGEs) and expression of receptor for AGEs (RAGE) in streptozocin (STZ)-induced diabetic nephropathy in rats, and the role of antioxidants on the AGEs-RAGE signaling.

METHODSDiabetic rats were induced by once intraperitoneal injection of STZ at the dose of 60 mg/kg, and randomly divided into the DN group (n=12, treated with normal saline by intraperitoneal injection, once daily), the extract of Ginkgo biloba (EGb) group (n=14, treated with EGb 300 mg/kg by oral administration, once every other day), and the alpha-lipoic acid (ALA) group (n=12, treated with ALA at the dose of 35 mg/kg by intraperitoneal injection, once every other day). Rats of the normal control group (n=10) were given vehicle citrate buffer at the dose of 60 mg/kg. Rats were sacrificed at the 12th week and the 20th week of this study. The four groups were compared in terms of body weight, blood glucose, renal function, 24-h urine protein. Renal pathological changes were observed by PAS staining. Oxidative stress indices were detected using spectrophotometry. The concentrations of AGEs were measured using fluoro spectrophotometry, and the expressions of RAGE were detected by Real-time PCR and Western blot.

RESULTSCompared with the normal control group, the 24-h urine protein quantitation was higher and the glomerular filtration rate increased in rats at the 12th week and the 20th week. The pathological tissue staining showed dilated glomerular mesangium, proliferated glomerular matrix, vacuolar degeneration of the renal tubular epithelium. Malonaldehyde (MDA) levels and 8-hydroxide radical guanine deoxyriboside (8-OHdG) levels increased, and catalase (CAT) and reduced glutathione hormone (GSH) levels decreased. The AGEs contents in serum and renal tissue homogenate increased. The expressions of RAGE mRNA and protein increased in the DN group at the 12th and the 20th week. The 24-h urine protein quantitation was reduced in the EGb group and the ALA group, with alleviated pathological changes, lowered MDA and 8-OHdG levels, increased CAT and GSH levels, decreased AGEs contents, and down-regulated RAGE expressions.

CONCLUSIONSAGEs contents increased and RAGE expression up-regulated in the circulation and local renal tissues in DN rats. EGb and ALA could inhibit AGEs production and down-regulate RAGE expressions by reducing oxidative stress, thus further improving the renal tissue structure and renal functions of DN rats. It had better application prospect in treatment and prevention of DN.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.
