ObJective To evaluate the value of contrast-enhanced ultrasonography microflow imaging (MFI) in detecting prostate cancer. Methods Sixty-five patients with serum prostate-specific antigen levels higher than 4.00 μg/L were evaluated with transrectal gray-scale,power Doppler,and MFI ultrasonography and then biopsy guided by ultrasonography. Biopsy was performed at twelve sites in the base,the mid gland and the apex in each patient. In these three transverse sections, when any of the three methods showed abnormality,the biopsy site was directed to the abnormal foci. Diagnostic efficiency of the three methods for prostate cancer detection was compared based on biopsy results according to patient and biopsy site. Results Overall prostate cancers were detected in 230 (29.5 %) of 780 specimens in 36(55.4%) of 65 patients. MFI could detect more patients(34) than gray-scale(26) and power Doppler(28) (P = 0.021, P = 0.031), 6(16.7%)of the 36 patients diagnosed with cancer were identified only by MFI. By biopsy site, MFI had higher sensitivity and overall accuracy (80.0% and 83.0%) than gray-scale (47.0% and 76.8%) and power Doppler (37.4% and 74.6%) ultrasonography(P <0.001, P<0.001 ; P = 0.001, P <0.001), while the specificity of MFI was 84.4%, lower than gray-scale (89.3%) and power Doppler (90.2%) ultrasonography(P = 0.009, P < 0.001). Conclusions MFI could detect more patients and improve sensitivity and overall accuracy by biopsy site than conventional uhrasonography.

BACKGROUND:The therapeutic effects of donkey-hide glue reinforcing bone oral solution on osteoporosis have been determined, but the exact effective mechanism is to be approached. OBJECTIVE: To investigate the effects of donkey-hide glue reinforcing bone oral solution (DGRBOS) medicated serum on osteoprotegerin (OPG)and its ligand(OPGL)mRNAexpression of osteoblast in fetal rats and explore the molecular mechanism of treating osteoporosis with DGRBOS. DESIGN: A randomized controlled trial. MATERIALS: The experiment was carried out from June 2003 to October 2004 in Bone Metabolic Laboratory of Department of Integrative Chinese and Western Medicine, Affiliated Hospital of Tongji Medical College,Huazhong University of Technology and Science. Totally 30 3-month-oldWistar rats (15 males and 15 females) were randomly divided into 3 groups, I.e. DGRBOS group, estrogen group and control group, with 10 rats in every group. 12 clean newborn SD rats were selected to isolate and cul ture osteoblast. METHODS: ①After intragastric administration for 7 days, medicated serum was prepared respectively from the three groups. ②Skull osteoblast isolated from newborn SD rats was made into single cell suspension, then after digestion and passage, the subcultured osteoblast cell was made into cell suspension. The cultured osteoblasts were divided into 5 groups and given equal volumes of drug liquor. The DGRBOS group was given DGRBOS-medicated serum at the concentration of 100, 500 and 1 000 g/L which was diluted by nutrient solution; the estrogen group was given tibolone-medicated serum of 100 and 1 000 g/L; the control group was givenonly culture fluid. Meanwhile every group was given calf serum (100 g/L) for further culture. ③The osteoblast proliferation was measured by antigenic MTT colorimetric analysis and 3H-TdR penetration method. The in tra-cellular BGP contents were evaluated by radioimmunity .The mRNA expression of OPG and RANKL in osteoblast was analyzed by Rt-PCR. ④ One-way analysis of variance was applied to compare data among groups. MAIN OUTCOME MEASURES: mRNA expression of OPG and PAN KL in osteoblasts from fetal rats after intervention by medicated serum ofDGRBOS or Livial. RESULTS: ①The osteoblast proliferation measured by antigenic MTT colorimetric analysis and 3H-TdR penetration method showed that the proliferation in the DGRBOS group and tibolone group was enhanced moresignificantly than that in the control group (P < 0.05-0.01), and reached maximal effect at the concentration of 500 g/L (P < 0.01), but when the concentration was over 500 g/L, the effect tended to saturate. The medicated serum with all concentrations from DGRBOS and estrogen groups could increase the contents of BGP in osteoblasts (P < 0.05). ②The mRNA expression of OPG reached the peak when the DGRBOS medicated serum was 1 000 g/L, and was obviously higher than that at the concentration of 100 and 500 g/L (P < 0.05). The expression in DGRBOS group at the concentration of 1 000 g/L and in the estrogen group at the concentration of 100 and 1 000 g/L was apparently higher than that of the control group (P < 0.01). ③The mRNAexpression of RANKL was the highest in DGR BOS group with 1 000 g/L concentration, and was markedly lower than that of the concentration of 100 and 500 g/L (P < 0.05). The expression in DGRBOS group at the concentration of 1 000 g/L and in the estrogen group at the concentration of 100 and 1 000 g/L was noticeably lower than that in the control group (P < 0.01).CONCLUSION: ①The DGRBOS could remarkably enhance osteoblast proliferation in dose-dependent and a dose-saturable manner, and the effect was close to that of tibolone. ②Partial mechanism of DGRBOS in treating osteoporosis might be promoting osteoblast proliferation and regulating OPG/RANKL expression.

Objective To investigate the relationship between alteration of gene in cyclic adenosine monophosphate(cAMP) signal transduction system in rats after myocardial damage and changes of cardiac function and ventricular remodeling. Methods Twenty eight male Wistar rats weighing 220 g to 250 g were randomly divided into three groups: acute myocardial damage group(AMD, n = 10), chronic myocardial damage group (CMD,n = 9 ) and sham-operation group (control, n = 9). Animal model of acute myocardial damage was established by ligation of rats left coronary artery in the AMD and the CMD groups. Rats in control group were treated similarly, except that the coronary suture was not tied. Hemodynamics and echocardiography were measured before rats were sacrificed 24 hours after operation in control and AMD groups but those in CMD groups were sacrificed 8 weeks later. Cadiocyte apoptosis were estimated by TUNEL method, cAMP levels in heart were tested by radioimmunity and the mRNA expressions for inducible cAMP early repressor (ICER), cAMP response element binding protein (CREB), phosphodiesterase 3A (PDE3A) and bcl-2 were assayed by real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR). Results The difference of left ventricular end diastolic diameter (LVEDD), left ventricular end diastolic pressure(LVEDP), maximal rising and falling rate of ventricular pressure,left ventricular systolic pressure (LVSP), eject fraction (EF) and fraction shortening (FS) were statistically significant among the three groups(F = 285.9, 196.8, 83.2, 80.4, 54.9, 196.6, 95.2, all P < 0.01). LVEDD[(7.03 ±0.28), (8.20 ± 0.27)mm] and LVEDP[(11.19 ± 2.89), (19.76 ± 3.34)mmHg] in AMD and CMD groups were significantly increased, compared with those in control group[ (5.05 ± 0.30)mm, (- 5.62 ± 3.01 )mmHg, all P <0.01 ]. While maximal rising rate[ (2964 ± 449), (2214 ± 434)mmHg/s] and falling rate[(- 2617 ± 441),(- 1891± 424)mmHg/s] of left ventricular pressure, LVSP[ (94.19 ± 4.03), (85.85 ± 6.39)mmHg], EF[ (41.6 ±5.9)%, (35.9 ± 4.1 )%] and FS[ (36.9 ± 4.6)%, (23.1 ± 4.9)%] of left ventricular in the two groups were lower than those in control[(4759 ± 406)mmHg/s, (- 4327 ± 388)mmHg/s, (116.29 ± 8.25)mmHg, (80.9 ± 5.6)%,(53.1 ± 4.3)%, all P < 0.01 ]. These changes in CMD group were more significant than those in AMD groups(P <0.05 or P < 0.01 ). The difference of apoptotic index, cAMP and expression of ICER, CREB, PDE3A mRNA and bcl-2 mRNA were statistically significant among the three groups(F= 172.5, 141.0, 540.8, 246.8, 165.1, 563.9,all P< 0.01 ). Apoptotic index[ (32.8 ± 4.2)‰, (18.4 ± 3.9)‰] and cAMP in heart[ (9.95 ± 0.30), (5.60 ± 0.25)nmol/kg] in AMD and CMD groups were increased compared to control group[ (3.9 ± 1.7)‰, (2.48 ± 0.29)nmol/kg,all P < 0.01 ], and those in CMD group were lower than in AMD group(all P < 0.01 ). Expression of ICER mRNA (1.434 ± 0.093, 0.942 ± 0.076) and CREB mRNA(5.70 ± 0.50, 2.64 ± 0.51) in AMD and CMD groups were higher, and expression of PDE3A mRNA(48.98 ± 8.14, 16.68 ± 8.46) were lower than those in control group (0.154 ± 0.063, 1.08 ± 0.35, 105.94 ± 12.61, all P < 0.01 ). The three genes in CMD group were fewer than those in AMD group(all P < 0.01 ). bcl-2 mRNA was up regulated in AMD group(4.55 ± 0.27) and was down regulated in CMD group(0.35 ± 0.15) compared to control(2.18 ± 0.30, all P< 0.01). Conclusions There is PDE3A-ICER positive-feedback loop leading to myocyte apoptosis and heart failure after myocardial damage. The downregulation of PDE3A mRNA observed in chronic myocardial damage may play a causative role in the progression of ventricular remodeling and heart failure, in part, by inducing ICER mRNA and promoting cardiac myocyte dysfunction.
