The specificity of prostate-specific antigen （PSA） for early intervention in repeat biopsy is unsatisfactory. Prostate cancer antigen 3 （PCA3） may be more accurate in outcome prediction than other methods for the early detection of prostate cancer （PCa）. However, the results were inconsistent in repeated biopsies. Therefore, we performed a systematic review and meta-analysis to evaluate the role of PCA3 in outcome prediction. A systematic bibliographic search was conducted for articles published before April 2013, using PubMed, Medline, Web of Science, Embase and other databases from health technology assessment agencies. The quality of the studies was assessed on the basis of QUADAS criteria. Eleven studies of diagnostic tests with moderate to high quality were selected. A meta-analysis was carried out to synthesize the results. The results of the meta-analyses were heterogeneous among studies. We performed a subgroup analysis （with or without inclusion of high-grade prostatic intraepithelial neoplasia （HGPIN） and atypical small acinar proliferation （ASAP））. Using a PCA3 cutoff of 20 or 35, in the two sub-groups, the global sensitivity values were 0.93 or 0.80 and 0.79 or 0.75, specificities were 0.65 or 0.44 and 0.78 or 0.70, positive likelihood ratios were 1.86 or 1.58 and 2.49 or 1.78, negative likelihood ratios were 0.81 or 0.43 and 0.91 or 0.82 and diagnostic odd ratios （ORs） were 5.73 or 3.45 and 7.13 or 4.11, respectively. The areas under the curve （AUCs） of the summary receiver operating characteristic curve were 0.85 or 0.72 and 0.81 or 0.69, respectively. PCA3 can be used for repeat biopsy of the prostate to improve accuracy of PCa detection. Unnecessary biopsies can be avoided by using a PCa cutoff score of 20.

目的:观察多西紫杉醇是否诱导前列腺癌PC-3细胞产生自噬,并初步探讨其可能机制。方法:实验应用MTT法测定细胞的增殖率;透射电镜观察细胞超微结构的变化;免疫荧光和Western blot分别定性和定量检测自噬相关蛋白Ⅱ型微管相关蛋白轻链3蛋白(microtubule-associated protein 1 light chain 3 typeⅡ,LC3-Ⅱ)、底物蛋白(sequestosome 1/SQSTM1,P62)表达水平,RT-PCR检测自噬相关基因Beclin-1 mRNA。结果:MTT结果显示多西紫杉醇能有效抑制PC-3细胞增殖(F=58.684,P=0.000);10-6 mol/L多西紫杉醇处理PC-3细胞24 h,即可发生明显的自噬,透射电镜观察到自噬体双层膜结构的形成。免疫荧光和Western blot结果显示多西紫杉醇处理PC-3细胞后P62表达降低(P=0.003、P=0.000、P=0.000),LC3-Ⅱ表达增强(P=0.002、P=0.000、P=0.000),RT-PCR结果显示多西紫杉醇处理PC-3细胞后可引起细胞Beclin-1 mRNA水平的上调(P=0.000、P=0.000、P=0.000)。结论:多西紫杉醇可以有效抑制前列腺癌PC-3细胞的增殖并诱导自噬,其发生可能与通过上调Beclin-1的mRNA水平有关。
