Kawasaki disease has replaced rheumatic fever as the most common acquired heart disease in childhood,but its etiology remains unknown. The development and analyses of animal models will help us under-stand KD and find new and effective therapeutic strategies for it. Among these existing animal models, mouse modelof coronary artery inflammation induced by a single intraperitoneal injection of lactobacillus casei cell wall extract is a relatively mature model. In this review,we present an overview of how this model established and some progress in research of the mouse model.

Portal vein tumor thrombus (PVTT) influence the prognosis of hepatocellular carcinoma.The development of PVTT is a multi-factor,multi-part process.According to anatomic features of the portal vein in the liver and tumor thrombus of HCC developing modes,a uniform tumor thrombus types system (typesⅠ -Ⅳ) is recommended.Multi-modal therapy based on surgery,interventional therapy and radiotherapy can improve the curative effect enormously.

Objective:To compare the dissolution results of doxazosin mesylate extended release tablets determined by a fiber-optic method and the imported drug registration standard method. Methods:The drug release process was determined directly with a FODT-601 fiber-optic medicine dissolution/ release rate process monitoring system. Aqueous solution of hydrochloric acid and sodium chloride was used as the dissolution medium, the paddle rotation rate was 75 r·min-1 , the detection wavelength was set at 246 nm while the reference wavelength was 550 nm. The detection length was 5 mm. Results:The standard curve of doxazosin mesylate was linear within the concentration range of 0. 468 1-11. 700 0μg·ml-1 and r values were greater than 0. 999 0. The intra-and inter-day RSD (n=6) was 1. 6% and 2. 0%, respectively. The recovery of doxazosin mesylate was 99. 0% and RSD was 1. 4(n=9). The results determined by the fiber-optic method were generally higher than those determined by the standard method, and there were some differences in the measurement results. Conclusion:Fiber-optic method shows the whole dissolution process objectively. It is particularly prominent in the research on the dissolution of rapid, extended and controlled release preparations. However, it can not replace the standard method yet.

BACKGROUND: Obesity has become the most common and costly metabolic problem in the world, and the genetic and environmental effects on the generation of obesity have become one of the focus factors in obesity research. Gene-chips have been reported as a useful tool in human adipose tissue research. OBJECTIVE: To determine the peripheral blood gene expression profile of Chinese adult obesities by gene chip technique for the first time. DESIGN: Randomized controlled observation. SETTING: Beijing University of Traditional Chinese Medicine. PARTICIPANTS: The experiment was performed at the Basic Medical College of Beijing University of Traditional Chinese Medicine between August 2003 and May 2004. Five obese patients, 4 males and 1 female, aged (21.4±0.9) years and three non-obese persons, 2 males and 1 female, aged (26.0±5.3) years were selected by the international body mass index (BMI) standard. The written informed consent was obtained from all subjects, and the research was approved by the medical ethical committee of Beijing University of Traditional Chinese Medicine. METHODS: Total RNA was extracted from peripheral blood, amplified and labeled. The quality and quantity of the processed samples were checked by Test3 array. The gene expression profiles were monitored by U133A set. The data was analyzed statistically, and the gene symbols with significant difference were searched in Gene BANK database. MAIN OUTCOME MEASURES: Gene expression signal. RESULTS: Compared with non-obese adults, 66 genes showed up-regulated expression and 28 genes showed down-regulated, of which 11 genes were up-regulated above twofold, and 6 genes were down-regulated above twofold. The results demonstrated that HLA-DQAI (human leucocytic antigens), CRAT, MAPKSI3 and DKFZP434N1923 genes were up-regulated above 4 fold, and HLA-DQA1 gene was even up-regulated above 20 fold. CONCLUSION: Significant differences in peripheral blood gene expression profiles in Chinese adult obesities are found for the first time. The results indicate that obesity is strongly associated with MHC class II antigen HLA-DQA1, and HLA-DQB 1, etc.

Objective To investigate the alterations of pulmonary dead space,pulmonary shunt fraction (Qs/Qt) and gas exchange after thromboembolism of lungs in swines and to evaluate the mechanism in respect of pathophysiology and implication.Methods Swine model of pulmonary thromboembolism was made by injection of thrombus into pulmonary artery.Eight swine were used for study of physiologic dead space (VDphy),alveoli dead space (VDalv),airway dead space (VDaw),Qs/Qt,pulmonary arterial pressure (PAP),oxygen partial pressure in arterial blood (PaO2 ),carbon dioxide partial pressure in arterial blood (PaCO2 ),alveolar-arterial O2 gradient (PA-aDO2) determined 30 min before thromboembolism and 0 min,30 min,60 min,120 min after thromboembolism.Results The results showed that VDphy,VDalv,Qs/Qt,PAP,PA-aDO2 increased markedly after thromboembolism in comparison with pre-thromboembolism (P ＜ 0.01 ),while PaO2 declined significantly (P ＜ 0.01 ),and the differences in VDaw and PaCO2 were not significant ( P ＞ 0.05 ).SNK test showed that VDphy and VDalv declined to be smaller at 60 min,120 min than those at 30 min,and PAP declined to be lower at 30 min,60 min,120 min than that at 0 min.Other variables did not change at different intervals after thromboembolism.Hemodynamics did not change significantly after embolization.Conclusions After pulmonary thromboembolism,a various of changes in pathophysiology happened such as increase in dead space,Qs/Qt and PA-aDO2 and decrease in PaO2,but PaCO2 did not change.

BACKGROUND:There are two ways to treat the enamel before bracket bonding: etching and sandblasting, but the few studies focus on the direct use of sandblasting technology on untreated enamel surface.
OBJECTIVE:To observe the damage of etchingversus sandblasting to the enamel surface, and to compare the bonding strength of metal brackets adhesive to isolated teeth with these two kinds of surface treatments.
METHODS:(1) Nine premolar teeth removed for orthodontic treatment were randomized into three groups: sandblasting, acid etching and polishing treatment groups. Surface roughening effects of these three kinds of treatments were observed under scanning electron microscope. (1) Another 40 premolar teeth removed for orthodontic treatment were randomized into two groups: sandblasting and acid etching groups. At 24 hours after bracket bonding, the shear strength was detected using mechanical testing machine, and the adhesive residue index of tooth surface was statisticaly calculated.
RESULTS AND CONCLUSION: (1) Under the scanning electron microscope, polishing treatment had no damage to the enamel surface; but in the other two groups, the enamel surface was damaged to varying degrees, especialy in the sandblasting group. (2) The bonding strength in the sandblasting group was significantly higher than that in the acid etching group (P < 0.05), but there was no difference in the adhesive residue index of tooth surface between the two groups (P > 0.05). These findings indicate that compared with the acid etching technology, the sandblasting technology can increase the bonding strength between the enamel and metal bracket, but it also results in more damage.
