?Objective:To study the influence of composite Danshen droplet pills on hemorheology in peripheral blood of patients with oral lichen planus (OLP).Methods:46 patients with OLP were treated by composite Danshen droplet pills for 8 weeks (oral administration,3 times/day,10 granules/time).The venous blood was taken and the hemorheology was studied with a LBY N6A hemorheology test machine before and after the treatment.Results:Effective results were observed in 33 patient and obvious effective results in 5,while no treating effect was found in 8 after treatment.Whole blood viscosity,blood plasm viscosity,erythrocyte aggregation indexs,thrombocyte aggregation rate,fibrinogen and ESR of the OLP patients were decreased ( P 0.05).Conclusion:The composite Danshen droplet pills may improve the hemorheology of OLP patients.

Objective To investigate the effects of Free fatty acids (FFAs) on extracellular matrix(ECM) mRNA expression and secretion.Methods Rat glomerular mesangial cells(HBZY-1 cells) were cultured in vitro and stimulated with OA in different concentration.The expression of collagen Ⅳ(Col Ⅳ) and fibronectin (FN) and transforming growth factor-beta1(TGF-?_1) mRNA were measured by semi-quantitative RT-PCR.The levels of Col Ⅳ and FN in cultured supernatant were determined by ELISA.Results The mRNA expression of Col Ⅳ, FN and TGF-?_1 of 25、100、400 ?mol/L stimulated OA groups were 0.94?0.17、1.16?0.15、1.28?0.19 and 0.82?0.11、0.97?0.07、1.09?0.08 and 1.15? 0.07、1.24?0.06、1.36?0.05 respectively , which increased significantly compared with their control group(0.73?0.16、0.53?0.09、 0.96?0.11 P

Aim To investigate the effects of Panax Notoginsenosides(PNS) on the gene expression and protein excretion of TGF-?_1 and CTGF of human renal tubular epithelial cell induced by uremic serum in vitro.Methods Forty sera from CRF patients and twenty sera from healthy volunteers were collected,gently mixed,inactived and separated respectively in steriled condition.HK-2 Cells were cultured in RPMI-1640 medium with 10% newborn calves serum and subcultured routinely.They were differentiated by phase contrast microscope and scanning electron microscope detection and cytokeratin18(CK-18) immunohistochemistry method.The protein levels of TGF-?_1 were examined by enzyme-linked immunoadsordent assay(ELISA).The protein levels of CTGF were examined by Western Bloting assay.The gene expression of TGF-?_1 and CTGF was detected by Semi-quantitative reverse trainscriptase polymerase chain reaction(RT-PCR).Results TGF-?_1 and CTGF gene expression and protein level were increased in 10% uremic serum groups compared with that of normal control group(P

10 000 D uremic toxin through promoting the gene and protein expression of CTGF in renal tubular epithelial cells in patients with chronic renal failure.

Objective:To study the effect of interleukin-18 on transdifferentiation in renal tubular epithelial cells(TECs).Methods:Human proximal tubular epithelial cell line(HK-2) was cultured in vitro.TECs were exposed to different concentrations(0,0.1,1,10 and 100 ng/ml) of IL-18 for 24,48 and 72 hours.At the end of each incubation,the expressions of the ?-SMA and TGF-?_1 mRNA were assessed by RT-PCR,the rate of ?-SMA expressing TECs was assessed by immunocytochemistry,and the expression of the ?-SMA protein was assessed by Western blotting.Results:(1)The expressions of ?-SMA and TGF-?_1 mRNA were increased significantly by a dose- and time-dependent manner when TECs were exposed to IL-18(P

Objective To develop a thyrocricoid puncture device to study its cure effect in rescuing patients who suffer from the obstruction of upper respiratory tract caused by war wounds,traffic accidents and pharyngolaryngeal tumor.Methods The clinical emergency cure effect of 268 cases of upper respiratory tract obstruction and 33 cases of sudden death were taken retrospective analysis,who received puncture and intubation through cricothyriod membrane ventilation and high-frequency oxygen supply.Results The achievement ratios in puncture and catheterization,oxygen supply,sputum suction and intratracheal administration on all the patients were very high.Conclusion The thyrocricoid puncture device is safe,easy to carry and operate,of mini-wound and effective in rescuing patients suffering from serious upper respiratory tract obstruction and cardiopulmonary resuscitation(CPR),can adapt to the scene of the wounded in war and peace and can be applied in clinic.

V infection group than in no infection group,while positive rate of other autoantibodies was not statistically different between the two groups.Conclusion Renal EBV infection may involve in the pathogenesis of LN by inducing the production of anti-Sm-Ab.

[ ABSTRACT] AIM:To investigate the effects of pathological products, urinary proteins and advanced glycosyla-tion end products ( AGE) produced in the progression of chronic kidney disease ( CKD) , on the structure and function of lysosomes in renal tubular epithelial cells ( TECs ) , and try to find a novel approach for preventing or delaying CKD. METHODS:The renal specimens of the untreated patients with minimal change nephrotic syndrome (MCNS), diabetic nephropathy (DN) or normal kidney were collected.The expression of lysosomal-associated membrane protein 1 (LAMP1) and cathepsin B ( CB) was studied in TECs by indirect immunofluorescent staining.Human renal tubular epithelial cell line HK-2 was incubated with 8 g/L urinary proteins or 100 mg/L AGE.The expression of LAMP1 and CB was investigated by indirect immunofluorescence and the activity of CB and cathepsin L ( CL) was measured by biochemical and enzymatic as-says.The degradation of DQ-ovalbumin was also determined.RESULTS: The lysosomal membrane permeabilization oc-curred in the TECs of MCNS and DN patients.After treatment with urinary proteins or AGE-BSA, the lysosomal membrane permeabilization of the HK-2 cells was increased.The activity of CB and CL and degradation of DQ-ovalbumin were de-creased as compared with normal control group.CONCLUSION:The digestive function of lysosome was decreased and ly-sosomal membrane permeabilization occurred in the TECs exposed to urinary proteins and AGE, which might be a key factor to induce the tubulointerstitial fibrosis.
