Objective To study the changes of detrusor microvessel density and apoptosis related factor PCNA and Bax in different phase of partial bladder outlet obstruction. Methods Forty Wistar rats were divided into control(n =10), sham-operation(n =10) , two-week obstruction( n = 10) and five-week obstruction group(n = 10). The expression of detrusor microvessel density and apoptosis related factors PCNA and Bax were evaluated with immunohistochemistry method. Results The average weight of bladder was (125.5?10. 1) ,(128.5?8.9) ,(380.0?12.4) ,(400.0?12.5) mg in control, sham-operation, two-week obstruction and five-week obstruction group, respectively. The difference between control, sham-operation group and obstruction group was significant (P 0. 05 ) . The expression of microvessel density was 2. 1?1.3,13.3?2.3,36.4?4. 1 and 37.3?5.6 in control, sham-operation, two-week obstruction and five-week obstruction group, respectively.

Objective To study the effect of arsenic trioxide(As 2O 3) combin ed w ith radiation on the killing of ovarian cancer cells. Methods Using MTT and FCM to detect the cytotoxic and apoptosis at different As 2O 3 concentrations combined with 2 an d 8 ?Gy radiation on ovarian cancer cells(SKOV-3). Radiation survival curves were det ermined by cloning assay with 5?mol/L As 2O 3 combined with 2, 3, 4, 6, 8 and 12?Gy radiation. Curve was used to evaluate the effect of cell killing. Results ⑴ Inhibition of cell proliferation seemed more dependent on the increase of As 2O 3 concentration, ⑵Cell survival rate was lower in the combination of As 2O 3 an d r adiation than As 2O 3 alone, ⑶The apoptosis ratio was increased in 2?Gy and As 2O 3 with increase in As 2O 3 concentration, ⑷D q , D 2 value was decr eased in t he combined As 2O 3 and radiation than radiation only (D q: 1.44 vs 2.78, D 0: 0.85 vs 1.30, SF 2: 0.42 vs 0.87), with radiation enhancement ratio of 1.53 and 2.0 7 according to D 0 value and SF 2. Conclusions Arsenic trioxide is able to enhanc e radiation effect obviously ,especially at lower radiation dose.

BACKGROUND: In recent years, nanoparticles has been rapidly developing in tumor hyperthermia, genophore research, and targeted drug therapy, particularly nanoparticle containing drug delivery systems will become another breach in tumor therapy.OBJECTIVE: To summarize the application and mechanism of superparamagnetic nanoparticles for cancer treatment in the medical field.METHODS: A computer-based online search was conducted in Medline for English language publications containing the key words of "superparamagnetic, nanoparticles, targeting" from January 2000 to October 2009. Relevant articles were also searched from CNKI with the same key words in Chinese from January 2005 to October 2009.RESULTS AND CONCLUSION: A total of 123 articles about targeting role of magnetic nanoparticles were included, and there were 24 in Chinese and 108 in English. Articles published earlier, duplicated, and similarly were excluded, and 30 references were finally included. Superparamagnetic nanoparticles characterized by targeting role under external magnetic field, and crystal of ferroso-ferric oxide did not has toxicity to cells. As a gene carrier and drug carrier, superparamagnetic nanoparticles were widely used in medical research and they also provided novel evidences for cancer treatment. By an external magnetic field, how to avoid a comprehensive system of phagocytic endothelial phagocytosis and prevent the course of treatment such as drug-induced thrombus is still inadequate.

The effects of synthetic oil used as dietary fat source on the body weight, organ weight, liver and serum lipids of rats during the hypercho-lesterolemic inducing period were investigated, and comparison was made with lard and soybean oil diets.Weanling albino rats were fed first with stock diet for 3 weeks. Bloods were collected from tails, and serum cholesterol contents were determined. Based upon the body weight and serum cholesterol level, animals were then divided into 5 groups. Four groups were fed respectively with synthetic oil, synthetic oil plus linoleic acid, lard and soybean oil diets, all were supplemented with 1% cholesterol. The, fifth group served as control, was fed with soybean oil diet without cholesterol. Body weights and serum lipids (cholesterol and triglyceride) were measured at intervals during the experiment. Organ weights and liver lipids (total fat, cholesterol and triglyceride) were determined at the end of the experiment.The results showed that there was marked sex difference between male and female rats, that is, synthetic oil diet caused significant lower body weights and lower serum cholesterol levels to female but not to male rats.Cholesterol inducing diets apparently increased the liver weights of all animals, yet fat accumulation only occured in those livers of rats fed with lard and soybean oil diets. The liver fat contents of animals of both synthetic oil and synthetic oil plus linoleic acid groups were at normal level.This experiment reveals that when dietary cholesterol intake is high, the use of synthetic oil as a dietary fat source for maintaining a normal lipid metabolic condition in the body seems beneficial.

BACKGROUND:Surrounding structure of intracristal ventricular septal defects(IVSD) and membranous ventricular septal defects(MVSD)is complicated,and it is difficult to perform transcatheter closure treatment.Corresponding animal models should be established to define an optimal interventional therapy.OBJECTIVE:To prepare the animal models of IVSD and MVSD under echoeardiogram location.DESIGN:Animal modeling experiment.SETTING:Department of Cardiology,Zhongshan Hospital Affiliated to Fudan University.MATERIALS:Six healthy adult dogs,irrespective of gender,were purchased from Shanghai Experimental Animal Center.Aorta and great saphenous vein stapler-puncher(St.Jude corporation,USA)was used.The main improvement is to cut the plastic shell even,thin,or shorter in order to reduce the resistance when puncturing the"purse"in the fight ventficle and the interventficular septum.Sonos 5500 multifunction ultrasonoscope(Philips,USA)was used,and the frequency of the probe was between 2.5-3.5 MHz.METHODS:Experiments were performed at the Zhongshan Hospital Affiliated to Fudan University and Central Laboratory of Shanghai Institute of Cardiovascular Disease from April to July 2006(biosaflety level 2).After anaesthesia,6 adult dogs were fixed at decumbent position.The interventricular septum was punetured to make the preparation with the location of echocardiography(ECHO)by using the modified aorta and great saphenous vein proximal stapler-puncher.Animal intervention met the Animal Ethical Committee of Fudan University.MAIN OUTCOME MEASURES:One week after the surgery,transthoracic echocardiography examination was used to check the VSD site,the highest shunt flow rate,the pressure difference between both sides of the VSD,as well as pulmonary artenal pressure.RESULTS:The VSD models were successfully established in three survivals and included in the final result.Two models of IVSD and one model of MVSD were examined by ECHO one week after the surgery.The diameter of VSD ranges from 1.8 to 3.6 mm.The Peak Flow Rate of the VSD ranges between 1.8 and 4.0 m/s.The pressure difierence of both sides of the VSD ranges between 42 and 51 mm Hg.The pulmonary arterial systolic pressure ranges from 23 to 29 mm Hg.CoNCLUSION:Located by the ECHO,it is possible to establish animal models of the IVSD and MVSD with the modified aorta and great saphenous vein proximal stapler-puncher.
