Objective To evaluate the effects of sevoflurane preconditioning on caveolin-3 expression during myocardial ischemia-reperfusion (I/R) in rats.Methods Healthy male Wistar rats,aged 6-8 weeks,weighing 250-300 g,were anesthetized with intraperitoneal pentobarbital 30 mg/kg and heparin 1 000 IU/kg.Their hearts were excised and perfused with K-H solution in a Langendorff apparatus.Thirty isolated rat hearts were randomly assigned into 3 groups (n =10 each) using a random number table:control group (group C),I/R group and sevoflurane preconditioning group (group SP).After 30 min of equilibration,group C was continuously perfused with K-H solution for 90 min,group I/R underwent 30 min of ischemia followed by 60 min of reperfusion,and group SP was perfused with K-H solution saturated with 2% sevoflurane for 10 min followed by 5 min washout with K-H solution,then underwent 30 min of ischemia followed by 60 min of reperfusion.HR,left ventricular enddiastolic pressure (LVEDP),+ dp/dtmax and-dp/dtmax were recorded at the end of equilibration,immediately before ischemia and at 30 and 60 min of reperfusion.Myocardial specimens were obtained from the cardiac apex for microscopic examination.Myocardial specimens were obtained from the left ventricle for determination of caveolin3 expression.Results Compared with group C,+ dp/dtmax and-dp/dtmax were significantly decreased immediately before ischemia,and HR,LVDEP,+ dp/dtmax and-dp/dtmax were decreased at 30 and 60 min of reperfusion in groups I/R and SP,and caveolin-3 expression was down-regulated in group I/R and up-regulated in group SP (P < 0.05).Compared with group I/R,HR,LVDEP,+ dp/dtmax and-dp/dtmax were significantly decreased immediately before ischemia and increased at 30 and 60 min of reperfusion,and caveolin-3 expression was up-regulated in group SP (P < 0.05).The pathological changes were significantly attenuated in group SP as compared with group I/R.Conclusion The mechanism by which sevoflurane preconditioning attenuates myocardial I/R injury in rats may be related to up-regulation of myocardial caveolin-3 expression.

Objective To investigate the antitumor mechanism of sodium arsenite on human gastric carcinoma cell line SGC-7901 in vitro. Methods MTT assay, light microscopy, electron microscopy, flow cytometry, and immunocytochemical staining were used to analyze the effect of sodium arsenite on biologic behavior of SGC-7901 cells. Results Sodium arsenite (2.50 ~ 40.00 ?mol/L) could inhibit the growth of gastric carcinoma cells, it depended on the duxation and concentration, and its 50% inhibitory concentration(IC50) was 8.69 ?mol/L after 72 hours' treatment. SGC-7901 cells were arrested significantly in G2/M phase treated with sodium arsenite for 48 and 72 hours. SGC-7901 cells presented typical morphologic feature of apoptosis and necrosis after exposure to sodium arsenite. Sodium arsenite up-regulated Caspase-3 protein expression in SGC-7901. Conclusion Sodium arsenite could obviously inhibit the proliferation of SGC-7901 cells, induce cell cycle arrest and apoptosis and necrosis of the cells. its mechanism is possibly associated with inhibition of elimination of ROS and the up-regulated expression of Caspase-3 protein.

In recent years, there's a new theory of lipid condensation or accumulation being the etiology for obstruction of qi in the chest result in heart disease. The theory believes that thick lipid exists in meridians. If one takes too much fatty diet, there will be lipid condensation or accumulation, resulting in disturbance of qi transformation in meridians,. Scholars explore the relationship of preventive treatment of disease by traditional Chinese medicine with lipid condensation or accumulation theory. This enriches the etiology of TCM.

BACKGROUND: The rehabilitation of maxillary loss is based on maxillary prosthesis,and the most difficult problem is that retention and support of maxillary prosthesis can hardly be achieved. The employment of implants in the zygoma region provides good basis for the retention and support of maxillary prosthesis. However,during implantation in the zygoma the pe ripheral tissues may be injured, and even induce failed implantation.OBJECTIVE: To study the bone structure of the zygoma so as to provide reference for implantation in this region.DESIGN:Randomized sampling for repeated observation measurement based on maxilla specimens.SETTING: The research was completed in the prosthodontic department of stomatological college and department of human anatomy of a military medical university.PARTICIPANTS:The experiment was carried out in the Department of Human Anatomy,Fourth Military Medical University of Chinese PLA from March to May 2002. A total of 73 adult maxilla specimens(38 from males and 35 from females) were provided by the Department of Human Anatomy,Fourth Military Medical University of Chinese PLA.METHODS: Quantitative measurement of bone structure of the zygoma region was made with the cursor ruler in the 73 specimens. T-test was used to analyze the measurement data.MAIN OUTCOME MEASURES: The data of measurement: bone thickness of the zygoma, width of the lower part of the zygoma, length of the zygoma, and the distance between lower part of the zygoma and orbital floor.RESULTS: ① Bone thickness gradually decreased from the interior-inferior borderline to the exterior-superior part of the zygoma. In males, the average bone thickness 10 mm,12 mm,14 mm and 16 mm away from the interior-inferior borderline of the zygoma was 6.97 mm, 6.45 mm, 5.75 mm and 5. 01 mm, respectively, in the upper part, and 7.03 mm, 6.69 mm, 6.28 mm and 5.89 mm in the lower part. In females, the average bone thickness 4 mm,6 mm, 8 mm and 10 mm away from the interior-inferior borderline was 6.95 mm,6. 55 mm,6.28 mm and 5.31 mm in the upper part,and 6.60 mm,6. 39 mm,6.26 mm and 5.75 mm in the lower part. ② The lower part of the zygoma was 21.39 mm wide in males and 17.20 mm in females. ③ The average length of the zygoma was 21. 12 mm in males and 19.58 mm in females. ④ The average distance between lower part of the zygoma and orbital floor was 4. 17 mm in males and 3.71 mm in females.CONCLUSION:In maxillary loss,the zygoma is an optimal region for double implants at a distance of more than 15 mm. In males, the implants of 3.6 -4.0 mm in diameter and 10 - 12 mm or 14 - 16 mm in lengthcan be employed; in females, the implants of 3.4 - 3.8 mm in diameter and 4 - 6 mm or 8- 10 mm in length can be employed.The differences in bone quantity between males and females are statistically significant in the zygoma,males' better than females', so they should be treated differently during clinical practice.

Object To investigate the preparation technique and optimal formulation of Breviscapin Sustained release Pellets (BSP) and the release mechanism of breviscapin from the pellets. Methods BSP was prepared by extrusion spheronization method. Based on the studies of influential factors, optimal formulation modified to release drug over 12 h was obtained by the orthogonal design. And release mechanism of breviscapin from BSP was established by equation fitting. Results Prepared BSP has such advantages as simple technique, uniformity in diameters and high loading with even contents. They can release drug for 12 h. And the release of breviscapin could be mainly controlled by diffusion associated with slight erosion. Conclusion Extrusion spheronization method is simple for the preparation of BSP, and useful for the large scale prodution.
