Prostate stem cell antigen (PSCA) is a cell surface antigen expressed in normal prostate and overexpressed in cancers associated with prostate, bladder and pancreas. The sensitivity of PSCA labeling is higher than PSA in prostate cancer. PSCA can be used in the preparation of protein vaccine and nucleic acid vaccine. Further studies are required to confirm its safety and efficacy as a diagnostic means.

The pertinent literature on application of traditional Chinese medicine (TCM) in hemopoietic stem cell transplantation was summarized, it indicated that the intervention of TCM could raise the mobilization effect, speed up the hemopoiesis and immunologic reconstruction after transplantation, decrease the incidence of complications, and prolong the life span of patients, showing a preliminary achievement.

Objective To explore the application value of ultra -high frequency ultrasound in detection of femoral artery stenosis in rabbits.Methods Twenty-four healthy male New Zealand white rabbits (body weight 2.5 -3.0 kg) were randomly divided into three groups , 8 rabbits in each group.Preparation of femoral atherosclerosis model : the rabbits were fed with high fat diet for 4 weeks, 8 weeks and 12 weeks after femoral artery balloon injury , respectively.The changes of cholesterol level were observed .We used ultra-high frequency ultrasonic probe to observe the femoral artery , to assess the diameter stenosis rate and peak systolic velocity (SPV) at the symptomatic side, and the histological areal stenosis was evaluated.Results 1.The blood cholesterol levels were increased after fed high cholesterol diet , with a significant difference among the groups (P <0.001); 2.There was a stenosis to a different degree in the modeling artery after fed high cholesterol diet for 4 wks, 8 wks, and 12 wks, and the stenosis degree was increased gradually .At 12 w, the degree of stenosis was higher than that at 4 w and 8 w, respectively, showing statistical significance ( P <0.001).At the symptomatic side, the peak systolic flow velocity was increased , and it was higher at 12 w than that at 4w and 8 w, respectively.3.With the extension of time, the arterial stenosis rate was increased along with the time course (P <0.05). Conclusions 1.High fat diet combined with balloon injury can cause varying degrees of rabbit femoral artery stenosis ; 2. Ultrahigh frequency ultrasound can clearly show different degrees of rabbit femoral artery stenosis , and can be used for detecting the lesions in animal models of peripheral vascular diseases .

Objective To identify the effects of the subthalamic nuclei(STN)high frequency stimulation(HFS)on striatal and nigral dopaminergic metabolism in rats.Methods The effects of subthalamie nuclei high frequency stimulation(STN-HFS)on striatal dopaminergie metabolism was investigated in free moving rats.Reverse transcriptase polymerase chain reaction(RT-PCR)and Western blot of striatal and nigral tyrosine hydroxyiase(TH)were performed.Results Our data suggest that STN- HFS elevated TH protein(0.99?0.14 vs 0.33?0.08,P

OBJECTIVETo investigate the effects of arsenic pentaoxide (As2O5) on the proliferation and apoptosis of endothelial cells and compare the effect of As2O5 and arsenic trioxide (As2O3) in vitro.

METHODSHuman umbilical vein endothelial cells (HUVEC) were incubated with or without As2O5 or As2O3 for a certain period. The proliferation profile of HUVEC was determined by methyl thiazolyl tetrazolium (MTT) method. The apoptosis of HUVEC was detected by microscopy and flow cytometry (FCM).

RESULTSAs shown by MTT assay, the viabilities of HUVEC were (72.5 +/- 13.8)%, (52.9 +/- 6.2)%, (15.0 +/- 12.8)%, and (13.8 +/- 13.2)%, respectively, in 0.5, 1.0, 5.0, and 10.0 mg/L As2O5 groups, of which the viabilities of HUVEC at 1.0, 5.0, and 10.0 mg/L of As2O5 were significantly lower than controls (P = 0.006, 0.007, and 0.008); however, the viability was not significantly different between 5.0 and 10.0 mg/L As2O5 groups (P = 0.119). In 1.0 mg/L As2O5 group, the cell viabilities were (88.4 +/- 6.3)%, (53.1 +/- 8.8)%, (30.7 +/- 7.9)%, and (16.3 +/- 4.6)%, respectively, at 24, 48, 72, and 96 h, of which the cell viabilities at 48, 72, and 96 h were significantly lower than controls (P = 0.042, 0.025, and 0.012). As2O5-induced apoptosis of HUVEC was observed by phase contrast microscope and flow cytometry with Annexin V/PI staining. After 48 hours of incubation, the IC50s of As2O5 and As2O3 were 1.1 and 0.3 mg/L, respectively.

CONCLUSIONSAs2O5 can inhibit the proliferation of HUVEC and the minimum effective concentration is 1 mg/L. Apoptosis is the main way that As2O5 induces the death of HUVEC. The inhibitory effect of As2O5 on HUVEC is weaker than that of As2O3.

Objective To investigate the imaging findings of the lacerating injury of the lung. Methods Ten patients of lung lacerating injury were examined by X-ray and CT within 1—5 h after injury. X-ray(2—5 times)and CT(3—5 times)examinations were repeated for 7 patients.Results The lung lacerating injury involved 10 sides and 14 lung lobes(21 lesions in total)in the 10 cases,among which 1 case involved the right upper lobe with 1 lesion,2 cases in the right lower lobe with 2 lesions,1 case in the right upper and lower lobes with 2 lesions for each lobe,3 cases in the left lower lobe with 9 lesions,and 3 cases in both the left upper and the lower lobes with 7 lesions.The X-ray findings were cavity-like shadows with smooth margin in 9 lesions(9/21),and patchy shadows of fogging margin in 12 lesions(12/21).The CT imaging findings included 6 pulmonary hematomas(6/21),and 15 cavitary lesions with air-fluid levels (15/21).In the 15 cavitary lesions,CT revealed 14 single cavities and 2 small cavities within a big cavity. On dynamic follow-up observation,the cavity was the biggest in 1—5 h after injury,but the hematoma was the biggest in 2—3 days after injury.Hematomas tended to absorb slower than the cavities.After 16— 32 days,all lesions revolved into small patchy or stripe-like shadows with slightly increased density. Conclusion Cavitary lesion with air-fluid level is the characteristic imaging finding of lung lacerating injury.CT surpasses X-ray plain film in revealing the details of lung lacerating injury.
