Objective To evaluate the quality of life (QOL) in adults with epilepsy.Methods The QOLIE-31 and the SDS were administered to 33 adults with epilepsy who met the entry criteria, and 17 healthy volunteers who had the similar personal characters. Results Patients' scores of SDS were adversely associated with seven of the eight QOL domains (except for medication effect) independent of other factors. Duration of the disease was the independent risk factor to overall health and medication effect. The GTC group (17 subjects) and the CPS group (16 subjects) were both obviously compared with the control group in medication effect (GTC group 61.0?23.8,CPS group 56.6?19.4,control 100.0?0.0) and seizure worry domains ( P

In the clinical skill evaluation,SP and the new technology OSCE for medical educational evaluation brought by SP can offer a vivid and complete exam atmosphere for the medical students,which have been widely applied by medical colleges and schools at home and abroad,with real,effective,reliable characteristics and broader development prospect. To induce the technology into TCM clinical evaluation is in accordance with the requirements of TCM educational development,which can make students better grasp clinical various basic skills within limited studying periods.

Pharmacokinetic analysis has attracted more and more attentions in the research field of bioactive natural product. However, there is limited study on the pharmacokinetics of polysaccharides. This paper focused on the research progresses of pharmacokinetics of polysaccharide, summarized the applications of chromatography, isotope labeling method, spectrophotometry, fluorospectrophotometry and biological assay in the analysis of polysaccharide pharmacokinetics, elucidated the behaviors of absorption, distribution, degradation and excretion of polysaccharide in experimental animals, and revealed the effects of physicochemical characteristic, administration dose and route on the pharmacokinetic properties of polysaccharide, which could be served as a reference for the related works.

OBJECTIVETo modify biomacromolecules, such as chitosan and collagen, to synthesize a mineralized template that will induce self-growing remineralization of tooth enamel.

METHODSNatural polycation polysaccharide chitosan was modified through phosphorylation to synthesize the polyanion derivative ofphosphorylated chitosan. Parent hydrogels com- bined with chitosan and collagen I were built through peptide binding reaction using genipin as a crosslinker. The gels self- assembled on the tooth's inert surface, which was stimulated by ultraviolet radiation. The bionic saliva provided mineralized ion, and then the hydroxyapatite assembled and grew in situ on the tooth.

RESULTSThe functional group P04(3-) (3,446 cm(-1)) was grafted on chitosan as confirmed by the Fourier transform infrared spectroscopy. The porous polyelectrolyte complex hydrogel formed by the interaction between the polycation chitosan and the polyanion phosphorylated chitosan could induce hydroxyapatite crystal nucleation and growth on the hydrogel fiber surfaces. The neonatal crystal was hydroxyapatite as confirmed by X-ray diffraction and was tightly connected to the tooth. A continuous structure of column crystals with sizes ranging from 30 nm to 60 nm was observed. The structure was in parallel direction similar to the direction of the enamel rod, and its hardness was close to dentin.

CONCLUSIONThe parent hydrogels that were easily obtained and controlled could mimic the template of the enamel mineralization and induce a self-growing hydroxyapatite, which is an important step in the structural bionics of enamel.

Objective To study a scoring method for assessing function status of cardiovascular system quantitatively. Methods First, exercise heart rate variability (EHRV) was obtained from the primary dynamic electrocardiogram (ECG) recorded during exercise testing. Then appropriate entropy, relative complexity, and other three parameters extracted from poincare dispersed-dot plot were extracted from the EHRV. Discriminant analysis was used to classify two extreme groups.Results Based on the values of two groups from the discriminant formula, a scoring formula was proposed and four ranks were divided according to different score domains. A novel scoring method was established. To validate the proposed scoring method, 60 middle-aged hypertensives, 50 elder subjects and 110 young healthy subjects were examined and scored. Conclusion Scores of 220 subjects are consistent with their real health status. The proposed scoring method reflects the status of the subject's cardiovascular system effectively.

Objective To investigate the effect of Helicobacter pylori (Hp) on the degranulation of mast cells and the permeability of gastric mucosa in BALB/c mice, in order to provide further evidence for the important role of Hp in the pathogenesis of chronic urticaria (CU). Methods Seventy healthy BALB/c mice were randomly classified into 3 different groups, namely, Hp group (n = 30), fed with Hp liquid once every 3 days for a total of 7 times, and two control groups, alcohol group (n = 20) fed with 45 percent alcohol solution, and bovine serum albumin (BSA) group (n = 20) fed with BSA 2% solution. Alteration in the blood sucrose level was used to assess the permeability of gastric mucosa. Toluidine blue staining of gastric mucosa was used to assess the total number of mast cells, the amount of degranulated mast cells and the per-centage of degranulated cells after feeding. Results There was a statistically significant difference between the total number of mast cells (F = 207.59, P < 0.01 ) and the percentage of degranulated mast cells (F = 108.16, P <0.01 ) among the three groups, with the highest number and percentage observed in the Hp group followed by the alcohol group. In both groups, the concentration of blood sucrose was increased after feed-ing, with a higher increase in the alcohol group; no significant change occurred in the concentration of blood sucrose in the BSA group (F = -4.06, P > 0.05 ), which differed significantly from the other two groups (F =277.03, P< 0.01 ). Conclusions Hp infection could increase the number and degranulation of mast cells in gastric mucosa, resulting in the release of histamines and vasoactive mediators, which may be related to the manifestation of urticaria.

Objective To investigate the expressions of RhoB and E-cadherin in non-small-cell lung cancer (NSCLC), and their clinical significances thereof. Methods Immunohistochemical staining was applied to detect expres-sions of RhoB and E-cadherin in 116 samples of NSCLC (NSCLC group) and 116 samples of normal lung tissues (control group). Correlations of expressions of RhoB and E-cadherin to clinical pathological parameters and prognosis were analyzed in two groups. Results The expression intensities of RhoB and E-cadherin were significantly lower in NSCLC group than those in control group (57.76%vs 87.07%,54.31%vs 85.34%,P＜0.01). There were significant differences in the expres-sion of RhoB between different pathological types, differentiation and lymph node metastasis in NSCLC group. There were significant differences in the expression of E-cadherin between different TNM stages, differentiation and lymph node metas-tasis in NSCLC group. The expression of RhoB was positively correlated with the expression of E-cadherin ( r=0.503,P＜0.01). The 3-year survival rates were significantly higher in patients with high expression of RhoB (83.93%) than those in pa-tients with low expression of RhoB (40.00%, Log-rank χ2=18.992,P＜0.01). The 3-year survival rates were significantly higher in patients with high expression of E-cadherin (85.11%) than those in patients with low expression of E-cadherin (44.93%, Log-rankχ2=16.680,P＜0.01). Further multivariate analysis suggested that both lower expressions of RhoB and E-cadherin and lymph node metastasis were prognostic indicators for NSCLC (P＜0.001). Conclusion The expressions of RhoB and E-cadherin showed a good correlation in NSCLC. Detecting the expression of RhoB combined with E-cadherin may give a clue on clinicopathological features and prognosis in patients with NSCLC.
