The prostate-specific antigen (PSA) test contributes a lot to the diagnosis and treatment of prostate cancer (PCa) and, along with imaging-guided prostate biopsy, has improved the diagnosis rate of lower-risk PCa and the accuracy of its clinical staging. However, many questions and controversies remain as to the choice of optimal biopsy strategies. Scholars differ in views about how to utilize PCa-related biomarkers to optimize the detection of initial and repeat biopsies. This review focuses on the present status of and advances in transrectal ultrasound-guided biopsy for PCa.

Objective To summarize the contrast enhanced ultrasonographic (CEUS) features of benign focal liver lesions, on and to investigate the value of contrast enhanced ultrasound techniques in the diagnosis of benign focal liver lesion. Methods The contrast enhanced ultrasonographic performance of 68 benign focal liver lesions cases which were dififcult for routine ultrasound diagnosis and conifrmed by pathology or follow-up were retrospectively analyzed. Chi-square test of four-fold table were used to compare the diagnostic coincidence rate of conventional ultrasound and contrast-enhanced ultrasound. Results The 68 cases of benign focal liver lesions included complex cysts (n=7), liver hydatids (n=2), liver abscess (n=15), focal nodular hyperplasia (n=8), angiomyolipoma (n=2), hepatocellular adenoma (n=4), focal fat accumulation (n=16), inlfammatory pseudotumor (n=12), solitary necrotic nodule (n=1), intrahepatic biliary cystadenoma (n=1). There were no enhancement among 7 complex cysts, 2 liver hydatids and 1 solitary necrotic nodule. Isoenhancement was detected in focal fat accumulation (n=16);hypoenhancement during the arterial phase and sustained enhancement during the portal or late phase was found in focal nodular hyperplasia (n=8) and angiomyolipoma (n=2). Grid-like enhancements during the arterial phase and isoenhancement or hypoenhancement during the portal phase, and hypoenhancement during the late phase was presented in liver abscess (n=15). Hyperenhancement during the arterial phase were detected in 4 cases of hepatocellular adenoma, 3 of which showed isoenhancement or hyperenhancement during the portal and delayed phase, one case showed hypoenhancement during the portal phase. Eight cases of all the inlfammatory pseudotumor showed no enhancement during all phases;3 cases showing grid enhancement during the arterial phase and the enhancement washed out rapidly;1 case showed mild edge enhancement during the arterial phase and hypoenhancement during the delayed phase. The solid part of the intrahepatic biliary cystadenoma showed hyperenhancement during the arterial phase and hypoenhancement during the portal and late phase.The central area showed no enhancement during all phase. The coincidence rate between pathology and conventional ultrasound diagnosis was 61.8%(42/68). The coincidence rate between pathology and contrast- enhanced ultrasound diagnosis was 92.6%(63/68). The coincidence rate of contrast-enhanced ultrasound diagnostic was higher than that of conventional ultrasound, with a statistically signiifcant difference (χ2=8.17, P < 0.01). Conclusion Real-time gray-scale contrast-enhanced sonography can improve the accuracy of the diagnosis and differential diagnosis for benign focal liver lesions.

Objective To study the effect of glucocorticoid receptor(GCR) on the treatment of patients with nephrotic syndrome(NS) and to observe the accommodation effect of herbal gynostemmae,acanthopanax senticosus harns on GCR levels.Methods The patients were divided into 3 groups: the healthy control group,treatment group Ⅰ(GC only) and treatment group Ⅱ(combination with herbal gynostemmae,acanthopanax senticosus harns and GC),radioligand binding assay was used to measure the GCR levels of each group.At the same time,the urine protein ratio within 24 hours was observed in each group.Results Compared with healthy control group,the GCR levels of treatment group Ⅰ and Ⅱ were both reduced,but after 4 weeks of treatment in the treatment group Ⅱ,not only GCR level recovered but also the urine protein were decreased faster than treatment group Ⅰ.Conclusions Herbal gynostemmae,acanthopanax senticosus harns can accommodate the GCR levels of children with NS.They can also eliminate urine protein and cure NS ideally.

OBJECTIVETo investigate the prevalence and subtype distribution of human papillomavirus (HPV) infection and its correlation with age among women in Beijing urban area, and provide some epidemiological evidence for the clinical application of HPV vaccines.

METHODSWe collected cervical specimens from 1999 women in the Outpatient Department of our hospital, performed genetyping of HPV-DNA, and analyzed the incidence of HPV infection in different age groups.

RESULTSHPV infection was detected in 502 (25.2%) of the 1999 women patients, with 391 (19.6%) cases of high-risk HPV, which included 326 (83.4%, 326/391) cases of single infection. HPV-16 was the most common type (21.2%, 69/326), followed by HPV-52 (19.3%, 63/326) and HPV-58 (16.0%, 52/326). The prevalence of HPV infection was the highest among the women aged 41 -50 years and the lowest among those over 60 years.

CONCLUSIONThe subtype- and age-specific distribution of HPV infection among women in Beijing urban area shows an obvious heterogeneity, which deserves due consideration in the clinical application of HPV vaccines.
