Objective To investigate effects of different doses of recombinant human bone morphogenetic protein-2 (rhBMP-2) on vascular endothelial growth factor (VEGF) expression in fetal mouse osteoblasts.Methods Calvaria osteoblasts of fetal mice of 19 days were cultured.The effects of rhBMP-2 at different doses and different action times on VEGF expression patterns in fetal mouse osteoblasts were observed with reverse transcrip- tion-polymerase chain reaction (RT-PCR) and Western blot staining.Results In the present study,RT-PCR detected a steady expression of VEGF mRNA in the control fetal mouse osteoblasts.The levels of VEGF mRNA increased in an apparent biphasic manner with a maximum stimulation (about 2-fold above the control,P＜0.05 ) in both VEGF mRNA species observed at 300 ng/mL of rbBMP-2.After 48 h of rhBMP-2 treatment,the VEGF mRNA levels approached those in the control.The VEGF mRNA levels appeared to be biphasic in rhBMP-2-treated cultures,showing peak induction at 3 and 24 h and remaining elevated at 48 b.Compared with the individual control value at each time point,an apparent maximum increase (about 2.5-fold above the control,P＜0.05) occurred at 6 h.The second peak induction,about 2-fold above that in the control,occurred at about 36 h.Conclusions The expression of VEGF mRNA is steady in the control fetal mouse osteoblasts.RhBMP-2 can promote the expression of VEGF in dose-dependent and time-dependent manners.

OBJECTIVETo analyze the parameters of urodynamic tests for patients with type-III B prostatitis and evaluate the significance of the results of urodynamic tests in the choice of therapies for this disease.

METHODSUrodynamic tests were performed for 87 type-III B prostatitis patients aged 22-45 (30.7 ± 8.5) years, who had moderate or severe lower urinary tract symptoms (LUTS) and failed to respond to routine therapy. Different treatments were administered according to the results of urodynamic tests followed by observation of the therapeutic effects.

RESULTSUrodynamic abnormalities were found in 70 of the 87 patients, bladder outlet obstruction in 28 (32.2%), detrusor overactivity in 25 (28.7%), bladder hyperesthesia in 18 (20.7%), low compliance in 10 (11.5%), detrusor-external urethral sphincter dyssynergia in 1 (1.1%), and impaired detrusor contractile function in 1 (1.1%). Treatments achieved obvious effectiveness in 26 cases (29.9%), effectiveness in 51 (58.6%), and no effectiveness in 10 (11.5%).

CONCLUSIONUrodynamic tests contribute significantly to the choice of therapies for type-III B prostatitis patients with moderate or severe LUTS.

Objective Labial gland biopsy is one of major diagnostic methods for Sj(o)gren's syn-drome(SS).Meanwhile,99TcmO-4 parotid scintigraphy has been proven useful for the clinical evaluation of SS.This study was performed to investigate the correlation between the two examinations and evaluate the semi-quantitative parotid scintigraphy in the early diagnosis and staging for SS patients.Methods There were 135 SS patients and 30 normal subjects as control group in this study.They all underwent 99TcmO-4 pa-rotid scintigraphy.Semi-quantitative analyses of parotid scintigraphy were conducted with parameters inclu-ding maximum accumulation ratio (MAR),maximum secretion ratio(MSR),time interval from stimulation to minimum count(tparotid),prestimulatory oral activity index (PRI) and poststimulatory oral activity index (POI).For comparison, the biopsy of labial gland was performed in each patient and the pathological se-verity was classified into grade 0,1,2,3,4 (also defined as subgroups).One-way ANOVA and q-teat were applied for the correlation analyses between the two examinations.Results There was significant difference between pathological subgroup 3 or subgroup 4 and the control in all the semi-quantitative parame-ters (q=6.79-38.64,P<0.O1).In subgroups 1 and 2,only PRI and POI showed significant changes compared with the control(q=8.33,8.63,all P<0.01).The pathological stages were negatively correla-ted with MAR(r=-0.679,P<0.01),MSR(r=-0.601,P<0.01),PRI(r=-0.724,P<0.01)and POI(r=-0.751,P<0.01),but only positively correlated with tparotid(r=0.364,P<0.01).Con-clusions Most semi-quantitative parameters of 99TcmaO-4 parotid scintigraphy may be well correlated with the pathological severity of labial gland biopsy in SS patients.Further,the semi-quantitative indices espe-eially PRI and POI may be helpful for the early diagnosis and staging of SS patients.

Objective To evaluate the efficacy and adverse effects of gefitinib in the treatment of fe- male patients with advanced adenocarcinoma of lung who had failed to previous chemotherapy.Methods These patients received 250mg of gefitinib orally,once daily until disease progression or development of intol- erable toxic reaction.They were evaluated one month after treatment and every other month thereafter.Results Among the 27 evaluable patients,there were 1 CR(3.7%),11 PR(40.8%),10 SD(37.0%)and 5 PD(18.5%). The overall response rate was 44.5%(95% CI 29%～68%);and 22 patients(81.5%)gained profit(CR+PR+ SD)from the clinical therapy(95% CI 62%～94%);the mean TTP was 7.2 months.Symptomatic improvement rate was 80.0%.The main adverse effects were mild rash and diarrhea.Conclusion gefitinib has significant efficacy in the treatment of female patients with advanced tung cancer who had failed to previous chemother- apy.Adverse effects are mild.gefitinib is a suitable therapy for these patients.
