  prostate cancer
The possibility of using AGR2 as a diagnostic marker of prostate cancer is discussed.
      
Calcitriol induces transcription of the placental transforming growth factor β gene in prostate cancer cells via an androgen-ind
      
Calcitriol (1α,25-dihydroxycholecalciferol) suppresses the growth of prostate cancer cells.
      
Growth suppression of hormone-sensitive LNCaP prostate cancer cells by calcitriol is believed to depend on androgens, but the mechanisms of the interactions between the calcitriol-and androgen-dependent signaling pathways is unclear.
      
It was assumed that calcitriol stimulates production of PTGF-β independently of 5α-dihydrotestosterone and that its effect on prostate cancer cell growth is partly mediated by an androgen-independent mechanism.

The cytoplasmic androgen receptor (AcR) and nuclear androgen receptor(AnR) densities wewe 305.70±461.68 and 363.04±391.44 pmol/g protein respectively, both were significantly higher than those of 36 benigh prostatic hypertrophy (BPH) and 9 normal prostate(NP).

The androgen receptors in biopsy specimens of 22 cases of human prostatic cancer(PC) were studied by radioligand binding assay. The cytoplasmic androgen receptor (AcR) and nuclear androgen receptor(AnR) densities wewe 305.70±461.68 and 363.04±391.44 pmol/g protein respectively, both were significantly higher than those of 36 benigh prostatic hypertrophy (BPH) and 9 normal prostate(NP). Among the prostatic cancers, the AnR/AcR ratios were significantly different between metastatic and primary cancers. This result suggested that there might be migration of AR from nucleus to cytosoi in the process of metastasis. The serum testosterone studied by RIA method are significantly lower than that of BPH and NP. Thawmounted autoradiography demonstrated that AR were mainly located in epithelial cells of the glandular tissue of prostate.

采用放射配基结合分析法测定人前列腺癌(PC)穿刺标本的雄激素受体(AR)含量,其胞浆受体(AcR)及胞核受体(AnR)分别为305.70±461.68,363.04±391.44pmol/g蛋白,与36例前列腺增生症(BPH)及9例正常前列腺组织含量相比均有显著性差异,显示前列腺癌的雄激素依赖性。22例前列腺癌患者中未转移组的AnR/AcR比值明显大于转移组,提示前列腺癌转移过程中AnR向胞浆转移的可能性。前列腺癌患者的血清睾酮水平明显低于前列腺增生症患者及正常人。放射自显影术显示雄激素受体定位以前列腺上皮细胞核为主,表明雄激素通过与核内受体结合调控肿瘤发生发展的可能性。

In order to evaluate CT in the differential diagnosis of prostatic diseases,120 cases were studied.Although in our series,the size of prostate increased with age,all were within the normal range,There were 36 cases of prostatic carcinoma and 84 cases of benign hypertrophy.Abnormal CT appearances of prostate such as inhomogeneous density, nodules,blunting or obliteration of seminal vesi-cle angle were more frequent in prostatic carcinoma but might also be present in hypertrophy of prostate.Combination of these...

In order to evaluate CT in the differential diagnosis of prostatic diseases,120 cases were studied.Although in our series,the size of prostate increased with age,all were within the normal range,There were 36 cases of prostatic carcinoma and 84 cases of benign hypertrophy.Abnormal CT appearances of prostate such as inhomogeneous density, nodules,blunting or obliteration of seminal vesi-cle angle were more frequent in prostatic carcinoma but might also be present in hypertrophy of prostate.Combination of these CT findings was mainly found in carcinoma despite of relatively low positive rate.CT could hardly differentiate benign prostatic diseases from malignant tumors, however,CT does pro-vide useful informations as to the extent and staging of tumor.

为了估价CT对前列腺疾病诊断的价值,笔者对120例全部经CT检查的病例作了研究。有关前列腺大小与年龄的关系,在120例中其大小尽管有随年龄增长而有所增大的趋势,但均未超过正常数值范围。120例中36例为前列腺癌,84例前列腺肥大。CT表现为密度不均、结节、精囊角变钝或消失;此多见于前列腺癌,亦见于前列腺肥大。然而CT的复合征象主要见于前列腺癌,只是阳性率相对较少。重要的是CT对前列腺的良、恶性鉴别是困难的。但对病变的延伸范围及前列腺癌的分期可提供较可靠的依据。

Serum prostate specific antigen. (PSA) was measured with radio - immunologic method in 14 pa-tients with prostatic carcinoma, 60 with BPH, 60 with chronic prostatitis and 40 with non - prostatic diseases. The change of PSA has also been observed in 8 cases with prostatic carcinoma who were treated by endocrine therapy. A significant difference in the positive rate of PSA was found between prostatic carcinoma and all the others(P<0. 01). The sensitivity of PSA in detecting prostatic carcinoma was 92. 9% ,Whereas...

Serum prostate specific antigen. (PSA) was measured with radio - immunologic method in 14 pa-tients with prostatic carcinoma, 60 with BPH, 60 with chronic prostatitis and 40 with non - prostatic diseases. The change of PSA has also been observed in 8 cases with prostatic carcinoma who were treated by endocrine therapy. A significant difference in the positive rate of PSA was found between prostatic carcinoma and all the others(P<0. 01). The sensitivity of PSA in detecting prostatic carcinoma was 92. 9% ,Whereas its specificity was 74. 4%. Although PSA is limited as a marker in screening prostatic carcinoma, PSA minght be of value for staging. Prognosing and monitoring the disea.se. The clinical symp-toms and objective sign were significantly correlated with the level of PSA in the serum.

用放免法测定14例前列腺癌,60例前列腺增生,60例慢性前列腺炎以及40例非前列腺疾病患者的血清PSA值;并随访观察8例前列腺癌患者接受内分泌治疗后PSA值变化。表明前列腺癌PSA阳性率明显高于其它疾病组(P<0.01),其敏感性为92.9%,特异性不高,为74.4%,作为前列腺癌的筛选指标有一定局限性。但对癌分期,疗效监测有较大价值;其数值升高或下降与临床主观和客观反应呈正相关关系。
