Purpose: To study the clinical application of intensity modulation radiation therapy (IMRT) in patients with prostate cancer. Methods: From May 2000 to June 2001, 14 patients with prostate carcinoma were treated . 12 patients underwent orchiectomy before IMRT. All patients were treated by IMRT with PEACOCK-MIMiC system ( CORVUS 3. 0 NOMOS CORPORATION) and VARIAN 6MV-photons. The prescription dose-time- fraction was 2.5 to 3. 0 Gy per fraction, 5 times per week , the total was 25 to 30 fractions, the total IMRT dose was 72 to 77 Gy, 5 to 6 weeks. Results: 3 months after IMRT , PR: 10(71.4%), NC: 4 cases and 6 month after IMRT CR: 6,PR: 8 cases. The overall response( CR + PR) rate were 100% . No Grade Ⅲ ,Ⅳ gastrointestinal ( GI) and genitourinary ( GU) toxicity occurred in any of the patients. Conclusions: IMRT is an effective approach for patients with prostate carcinoma. The dose of 72 to 77 Gy was safe.

Cancer stem cell (CSC) theory supposes that CSCs are the origin of tumors occurrence, progression,drug resistance, recurrence and metastasis. Cancer is not only a genetic disease but also a stem cell disease. Increasing evidence suggests the existence of CSCs in some solid tumors.

Objective To develop a reliable and reproducible model of ischemic stroke .Methods Male C57BL/6J mice were randomly divided into three groups:three-vessel occlusion (3VO, 15-min temporary occlusion of the bi-lateral common carotid arteries superimposed on a permanent occlusion of the right distal middle cerebral artery , n=20 ) , suture MCAO control ( n=20 ) , and sham-operated group ( n=10 ) .At 24 h functional outcome was as-sessed using corner test , cerebral ischemic lesion was determined by TTC staining ( n=10 ) , and then the surviral rate was measured till day 7 (n=10).Results The 3VO group got significantly lower neurological deficit score as compared to sham-operated group ( -0.7 vs -0.04 , P<0.01 ) .Infarct volume of mice in 3 VO group was 17.6%±1.6%, while 42.6%±15.0%in MCAO group ( n=10 ) .The 3 VO group got a significantly increased 7-day survival rate compared to suture MCAO group (90%vs 60%, n=10).Conclusions The present three-ves-sel occlusion model is stable and reliable for research on ischemic stroke .

BACKGROUND:The authors' experiments of the earlier stage proved that the hypocrellin B photodynamic therapy(HB-PDT) can cause selective injuries to choriocapillaries. It is not known whether changing the therapeutic parameters would gain a different result regarding the choriocapillaries after the hypocrellin B photodynamic treatment for a month.OBJECTIVE: To observe the features of Chinchilla rabbit choriocapillaries after HB-PDT treatment and to probe into the research prospect of using HB-PDT to treat choroidal neovascularization (CNV) and of using green light as the light source for PDT.DESIGN: A single sample study.SETTING: Laser Department of the Chinese PLA General Hospital.MATERIALS: The trial was conducted at the Laser Department and the Department of Pathology of the Chinese PLA General Hospital as well as the Department of Photoelectric Engineering of Beijing University of Science and Engineering. The materials included photosensitizing agent hypocrellin B (HB), a green laser transmitter, fundus fluorescence camera and transmission electronic microscope.METHODS: The 532 nm green laser transmitter and slit-lamp microscope were connected by light fiber. Chinchilla rabbits of 2.5 to 3.5 kg was narcotized generally and HB(1. 0 mg/kg) was injected into the marginal ear vein. HB was excited with the green laser of 532 nm. The power density of the light spot on fundus was 300 mW/cm2, and the energy density 30 J/cm2. Laser was applied immediately after HB injection and the diameter of the light spot was 2 000 μm. Direct observation of retina, fluorescein fundus angiography and observation with light microscope and electronic microscope were conducted on the 1st, 7th and 28th days respectively after PDT to find the biological features of retina and the choroid.MAIN OUTCOME MEASURES: Non-selective injury of retina through direct observation of the fundus; obliteration of the choriocapillaries detected through fluorescein fundus angiography; the position and extent of non-selective injury in retina and the structural changes of the choriocapillaries observed through the light microscope; the ultrastructural changes of the fundus observed through the electronic microscope.RESULTS: One day after PDT, photodynamic thrombosis was formed in choriocapillaries being illuminated and the external layer of retina was apparently injured. On the 7th day, injury of endothelial cells of the choriocapillaries was aggravated without obvious changes of the main vessels of choroid. On the 28th days, fibrous tissue appeared where the choriocapillaries had been and the glass membrane became thickened. Repair and proliferation of RPE cells appeared in the laser illuminated area.CONCLUSION: The biological effect in the target area and non-selective injury in the non-target area began to appear from the 1st to the 7th day after PDT and continued to aggravate. That would be repaired by fibrous tissues from the 28th day. It deserves further studies to treat age-related macular degeneration or other diseases in fundus characterized with choroidal neovascularization.

OBJECTIVE:To investigate the satisfaction degree of outpatients on policy of separation of clinical pharmacy from 4 third grade hospitals in Shanghai,and provide reference for promoting medical reform policy. METHODS:Parts of outpatients in the 4 new suburb third grade hospitals were investigated by the questionnaire and interview in Shanghai city,and the data was sta-tistically analyzed by Excel software and SPSS 19.0 software. RESULTS:Totally 400 questionnaires were sent out and 368 were valid with effective recovery of 94.3%. The awareness rate of medical separation policy was 81.3% in the outpatients;55.5% of outpatients thought that medicine cost savings effect was not obvious;the overall satisfaction of patients was 91.6%,and the high-est of satisfaction was the service attitude and the lowest was medical expenses. CONCLUSIONS:Policy of separation of clinical pharmacy has reduced the medical expenses,guided the triage treatment of patients partly and improved the satisfaction of patients. It is suggested to shorten the waiting time by optimizing examination process,strengthen price regulation in drug,standardize pro-duction and distribution process,improve use rate of essential medicines and promote clinical rational drug use for further improve-ment of satisfaction.
