Objective To investigate quantitatively the thermal sensation characteristics of the patients with facial palsy and the value of quantitative thermal test (QTT) in prognostication.Methods The QTT threshold of the fore ear and cheek of 30 patients with peripheral facial palsy was tested,their facial nerve conduction velocity was measured,and House-Brackmann facial nerve grading system was used to estimate facial nerve function at 2～3 weeks,a month,two months and half a year post onset.Results It was found that 12 out of 30 patients had abnor- mal QTT threshold value;the majority of them suffered from herpes virus and diabetes.In those with abnormal QTT, 8 were with diabetes mellitus (account for 66.7%),3 with partial shingles (account for 25%),and 1 with positive serum virus infection (account for 8.3%).Those with normal QTT were significantly different from those with abnor- mal QTT,with regard to the House-Brackmann rating scores after 2 and 6 months post onset (P

Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.

The diethyl sulfate (DES) mutagenesis was chosen for the mutagenic treatment to Phellinus igniarius, and the relationship of mutagenesis time and death rate was investigated with 0.5% DES. The differences of mycelial growth speed, liquid fermentation mycelia biomass, morphology and pigment classes of secondary metabolites production speed and antioxidant activities of metabolite products were discussed. The study displayed that DES mutagenesis could change mycelial morphology without obvious effect on mycelium growth, and the DES mutagenesis improved antioxidant activities of the active ingredients of P. igniarius and had more antioxidant activity of hypoxia/sugar PC12 nerve cells than that of P. igniarius.

The objective of the present study was to establish a method based on principal component analysis (PCA) for the study of transdermal delivery of Chinese medicinal formulae, and to choose the best penetration enhancers for Qingfei Xiaocuo gel depend on this method. Using improved Franz type diffusion cell and excised rat skin in vitro as transdermal barrier, the receptive solution fingerprint was established by HPLC, harvesting the areas of the common peaks in the fingerprint, then the total factor scores of the concentrations at different times were calculated using PCA and were employed instead of the concentrations to compute the cumulative amounts (Q12) and enhancement ratio (ER), the latter of which were considered as the indexes for optimizing penetration enhancers. Compare to the control group, the ER of the other groups increased significantly and furthermore, 2.5% azone with 2.5% menthol manifested the best effect. PCA represent most information in the receptive solution, the method above could choose the best penetration enhancers, it could be a reference for the study of transdermal delivery of Chinese medicinal formulae.

Nerve growth factor is one of the most important factors playing an important role in regulating the growth, development and survival of the neuron. The purified NGF from human placenta has been reported, the tissue from which can be isolated the NGF is very limited. It is important for basic research and clinic application to expression hNGF by genetic engineering. By polymerase chain reaction,gene fragment encoding the mature part of ?-NGF was amplified using the DNA of human placenta as template. The fragment was sequenced and inserted into expression vector pET-15b, and the recombinant expression vector pET15b-NGF was transformed into E.coli BL21(DE3)pLysS. After inducing with IPTG the NGF was higher expressed up to 25% of the total cell proteins. The expression product was purified with metal chelate affinity chromatography on Ni-IDA agarose under denaturing condition. The purity of rNGF was higher than 90% and yield of rNGF was 4.56mg/L expressing bacteria. SDS-PAGE revealed the NGF expression product had a Mr 16kDa. Western-blot displayed the recombinant product had strong immunological activity with rabbit anti-human ?-NGF polyclonic antibodies. The expression products were dealed with solubilizing inclusion bodies and refolding protein. The test of nerve fiber growth of chicken embryo DRG neurons displayed rNGF had biological activity.

Objective To evaluate the precision of GFR using Gates method and compared with the results from renal pathological changes. Methods Twenty-seven patients whose 99Tcm-DTPA renograms had no obvious uptake phase were enrolled in Group A, and 27 patients whose 99Tcm-DTPA renograms had obvious uptake phase were enrolled in Group B. The measurement of GFR by Gates method was compared to the creatinine clearance measured and predicted by Cockroft-Gault (C-G), modification of diet in renal disease (MDRD) and SCr level. Renal pathological changes in two groups were compared using Pearson correlation and t test analysis. Results In Group A, GFR determined by Gates method did not show correlation with that estimated by C-G or 1/SCr (r = 0. 357,0. 376, both P ＞0.05), but was significantly correlated with GFR estimated by MDRD(r = 0. 440, P ＜ 0.05). In Group B, GFR determined by Gates method showed significantly correlation among GFR estimated by MDRD, C-G, and 1/SCr (r =0. 471, 0. 527,0. 452, all P ＜ 0.05). Renal tubulointerstitial damage score in Group A was higher than that in Group B (7.15±2.32, 3.70±3.06, t=4.66, P ＜0.001). Conclusions GFR determined by Gates method is less precise when 99Tcm-DTPA renogram has no obvious uptake phase than that when 99Tcm-DTPA renogram has obvious uptake phase. Renal tubulointerstitial damage is a strong indicator of no obvious uptake phase in 99Tcm-DTPA renogram.

OBJECTIVETo investigate the effect of effective parts of Zingiber officinal (EPZ) on the adhesion of ECV-304 cells with monocytes cultivated in vitro and on the expression of monocyte chemotactic protein-1 (MCP-1) and adhesion molecules.

METHODThe model of ECV-304 cell oxidative stress injury was established by hydrogen peroxide (H2O2). Then EPZ-contained blood serum was taken as experimental drug. The adherence of monocytes to endothelial cell were measured by method of rose Bengal. The total RNA of cells was extracted. The intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and MCP-1 mRNA expression in cells were detected by RT-PCR. MCP-1 protein expression were detected by ELISA.

RESULTEPZ could decrease the adhesion of monocytes with ECV-304 cells obviously. Meanwhile it could diminish the expression of ICAM-1, VCAM-1 and MCP-1 in injured ECV-304 cells.

CONCLUSIONEPZ could inhibit H2O2-induced ICAM-1, VCAM-1 and MCP-1 expression in ECV-304 and could inhibit the adherence of monocytes to endothelial cell, which may result in the protect effect in endothelial cells.
