ObjectiveTo observe the therapeutic effects of Shenxiong glucose injection in the patients with chronic kidney diseases.Methods Seventy-eight patients with chronic kidney disease were given intravenous glucose injection 200 ml,qd,for 2 weeks.The patients who were complicated with diabetes would be given insulin 2 U/100 ml.Before and after Shenxiong injection treatment,24 h urinary protein,blood urea nitrogen ( BUN),creatinine ( Cr),hemoglobin ( Hb),albumin ( ALB),hematocrit ( HCT),fiber fibrinogen (FIB),cholesterol (TC) and triglyceride (TG) were measured and compared.Results After 1 course of Shenxiong treatment,the serum BUN,Cr,FIB,24 h urinary protein,Hb and HCT ( [ 15.70 ± 3.62 ] mmol/L vs.[6.74 ± 1.56 ] mmol/L,[ 564 ± 65 ] μmol/Lvs.[ 189 ± 43 ] μmol/L,[ 0.08 ± 0.01 ] g/L vs.[ 0.04 ± 0.01 ] g/L,[7.96 ±3.45]g vs.[3.60 ± 1.92]g,[83.6 ±10.5]g/L vs.[79.5 ±8.7]g/L,[0.43 ±0.0] vs.[0.39 ±0.06 ] were decreased,and ALB ( 28.7 ± 8.6) vs.( 36.8 ± 6.2) was increased.The difference was statistically significant (t =3.1 1,2.98,3.04,2.82,2.02,2.23,P＜0.01 for all).TC and TG were not changed much after the treatment.ConclusionShenxiong injection can improve the kidney function,lower Fibrinogen and urine protein,which may effectively slow down the progress of chronic kidney disease and improve the life quality.

ObjectiveWith a GcneChip(R) cxpression analysis,98 known gencs and 31 exprcssed sequence tags (ESTs) were found to be differentially expressed between KK/Ta and BALB/c kidneys.To further screen the susceptibility genes for diabetic nephropathy,the temporal and spatial expression patterns of differentially expressed gene-adipsin were investigated.MethodsThe body weight,blood glucose,urinary albumin/creatinine ratio,and renal pathological changes of KK/Ta and BALB/c mice were measured at the 7,20,28 and 36 weeks of age.Total RNA was extracted from the kidney,heart,liver,lung,and brain.The temporal and spatial expression patterns of adipsin in diabetic KK/Ta mice were examined by competitive RT-PCR.The correlation analysis between adipsin expression and albuminuria level was carried out.ResultsThe mRNA expression of adipsin was found in the kidney,heart,lung,and brain,but not in liver.The expression of adipsin in diabetic KK/Ta mice at 20 weeks of age was significantly down-regulated in kidney,heart,and lung than that in age-matched BALB/c mice,and unaltered in brain.Adipsin expression in KK/Ta kidneys was significantly down-regulated with aging and negatively correlated to urinary albumin/creatinine ratio( r =-0.807,P ＜ 0.05).ConclusionsThe expression of adipsin mRNA was downregulated in kidney,heart,and lung in diabetic state.Adipsin expression in KK/Ta kidneys was negatively correlated to urinary albumin/creatinine ratio.It might be a candidate gene for diabetic nephropathy.

Objective To observe imaging characteristics and changes of vivo two-dimension multi-voxel proton magnetic resonance spectroscopy (~1H-MRS) in the rabbit models of VX2 hepatic carcinoma after high intensity focused ultrasound (HIFU) treatment. Methods VX2 hepatic carcinoma models were established in 20 New Zealand rabbits. Routine MR and 2-dimentional ~1H-MRS scanning were performed before and after HIFU treatment. The central regions of interest (ROI) of the VX2 tumor, tumor border and paratumor normal liver tissues were selected. The Cho/Cr and Lip/Cr of the same ROI before and after HIFU treatment were compared. Results Total 28 satisfied spectrogram diagram of ~1H-MRS were brought into statistical analysis. Of all the spectra, 6 metabolite peaks were detected as lipids (Lip), glutamine and glutamate complex (Glx), choline (Cho), lactate (Lac) and creatine (Cr). Cho and Lac peak in tumor center and tumor border regions after HIFU treatment were higher than those before HIFU treatment. Lip peak was lower than before, and major metabolites of paratumor normal liver tissues did not changed significantly. Statistical differences of Cho/Cr and Lipid/Cr of tumor center and border region were found between before and after HIFU treatment (P＜0.05). Conclusion Two-dimension multi-voxel ~1H-MRS can reflect major changes in the level of metabolites of different ROI for hepatic VX2 carcinoma after HIFU treatment.

Objective To explore the mechanism of up-regulation of tubular liver-type fatty acid binding-protein (L-FABP) in IgA nephropathy (IgAN) and its renoprotective role.Methods Murine mesangial cells (MCs) from primary cell culture were cultured with aggregated IgA (AIgA) (10 to 250 mg/L) for 48 hours. The supernatant after culture was collected as AIgA-MC medium. Murine proximal tubular cell line (mProx) stably expressing human L-FABP (hL-FABP) by transfection (mProx-L) were cultured with AIgA, AIgA-MC medium and /or neutralizing anti-TNF-α antibody and recombinant murine TNF-α, respectively. AIgA-MC medium (AIgA final concentration was 25 mg/L) was cultured with mProx and mProx-L cells. The mRNA expressions of hL-FABP and MCP-1 of the cells were detected by real-time PCR. The protein expressions of hL-FABP and 4-HNE of the cells were detected by Western blotting. Results (1) The hL-FABP mRNA and protein expression stimulated by AIgA-MC medium was significantly higher as compared to AIgA (P＜0.01). (2) Pre-incubation of neutralizing anti-TNF-α antibody (final concentration was 1 and 5 mg/L) with mProx-L cells could significantly suppress the up-regulation of hL-FABP protein expression induced by AlgA-MC medium (P＜0.05 and P＜0.01).(3) Recombinant murine TNF-α (final concentration was 50 and 250 ng/L) also induced a significant up-regulation of hL-FABP expression (P＜0.01). (4) After the stimulation of AIgA-MC medium, both 4-HNE protein expression and MCP-1 mRNA expression were significantly suppressed in mProx-L cells compared to those of mProx cells (P ＜0.05 and P＜0.01). Conclusion Mesangial cell-derived TNF-α can induce up-regulation of tubular L-FABP expression. Overexpression of tubular L-FABP may lessen the progression of IgAN by reducing oxidative stress and inflammatory mediators.

Objective .To prove aristolochic (AA) caused vascular endothelial cells (VEC) injury via intracellular calcium overloa-ding and investigate the mechanism of calcium dobesilate antagonism. Methods Human umbilical vein endothelial cells (HUVEC) were cultured in vitro, and randomly divided into three groups: Control group, AA group, intervention group. Microscope and transmission elec-tron microscopy were used to observe changes of cell morphology and ultrastructure. ELISA method were applied to determine thrombomedu-lin (TM) in cell culture supernatant, fluorescent indicator FLuo-3/AM and intracellular calcium concentration ([Ca2+]. Results TM val-ue and average [Ca2+] i of AA group were significantly higher than that of control group (P < 0.05). Compared with the AA group, when the concentration of calcium dobesilate was 25 μM or 50 μM, TM value and average [Caz +] significantly decreased in intervention group (P < 0.05). Compared with control group, endoplasmic reticulum was pool expansion shaped, and mitochondrial cristae was absent in AA group cells. Endoplasmic reticulum and mitochondria patterns in the intervention group cells showed some improvement, compared with AA group. Conclusion AA induced VEC calcium overloading, 'I'M secretion and injury of endothelial ceils, endoplasmic reticulum and mito-chondria destruction. Dabesilate calcium could protect endoplasmic reticulum and mitochondria and reduce AA induced VEC calcium over-loading, and these could protect VEC.

Objective To investigate the renoprotection of tubular L-FABP in murine IgA nephropathy (IgAN) induced by bone marrow transplantation(BMT). Methods IgAN models were reconstituted by BMT from IgAN-prone mice into mice (Tg) transgenically tubular overexpressing human L-FABP (hL-FABP) and wild type (WT) mice. These recipients were sacrificed at 6 and 12 weeks after BMT and their kidneys were collected. The expressions of hL-FABP, fibronectin (FN)and monocyte chemoattractant protein-1 (MCP-1) mRNA were detected by real-time PCR. hL-FABP,FN, type Ⅳ collagen (Col Ⅳ ), hemeoxygenase-1 (HO-1) and 4-hydroxy-2-nonenal (4-HNE)modified proteins were detected by Western blotting. The distribution of hL-FABP and FN protein in kidney was detected by immunohistochemistry. The level of serum IgA, urinary albumin and urinary hL-FABP was detected by ELISA. Results (1) IgAN was reconstituted in both Tg and WT mice by BMT: mesangial IgA deposition and up-regulation of serum IgA. The levels were not significantly different between two groups (Tg-ddY and WT-ddY). (2) hL-FABP was expressed in proximal tubular cells of normal Tg mice. The mRNA (1.62±0.32 vs 0.46±0.09, P＜0.01) and protein expression (1.74±0.76 vs 1.14±0.31, P＜0.01) of hL-FABP was up-regulated in Tg-ddY kidney and urinary hL-FABP level (μg/g creatinine) was significantly increased (59.87±26.75 vs 31.01±14.86, P＜0.05) at the 6th week after BMT. (3) WT-ddY mice showed a significantly higher urinary albumin level (mg/L) (828±656 vs 82±22, P＜0.01), severer mesangial matrix expansion (P＜0.01),more glomerular FN and Col Ⅳ deposition at the 12th week. (4) Up-regulation of renal hL-FABP was associated with significant suppression of renal HO-1 expression (P ＜0.05),accumulation of 4-HNE modified proteins (P＜0.05) and MCP-1 mRNA expression (P＜0.01) in Tg-ddY mice. Conclusion Tubular L-FABP may lessen the progression of glomerular damage at early stages of IgAN by reducing oxidative stress and inflammatory mediators.
