Results Compared with that in the NP tissues, the number of α-SMA positive cells increased significantly in BPH tissue, and the number of vimentin positive cells increased moderately in the stroma and prominently surrounding the acinus and in the basal layer. In BPH tissue, the myosin and ERα staining signal was lost in the stromal cells surrounding the acinus, and the positive staining cells gathered into bunches in the stroma far away from the acinus, while the positive cells were sporadically distributed in the NP tissue. The PCNA positive cells increased moderately in the stroma and increased significantly in the basal layer.

结果 与NP相比在BPH中，α-SMA阳性染色细胞显著增加；波形蛋白在间质中阳性染色细胞有所增加，在腺泡基底层及临近腺泡外层间质中阳性染色细胞明显增加；在临近腺泡外的数层间质细胞中肌球蛋白和ERα由部分阳性变为完全阴性染色，而在远离腺泡的间质中其阳性染色细胞由散在斑块状分布变为簇状密集排列；PCNA在间质中阳性染色细胞有所增加，在基底细胞层中阳性染色细胞显著增加。

The levels of schistosome circulating cathodic antigen in serum and urine were detected parallelly by McAb-Dot-ELISA. In 81 acute cases, the positive rates in serum and urine were 96.30% and 66.67%(P＜0.01) but the combined positive (positive in serum and／or in urine) rate reached 100%, while in 109 chronic cases, they were 77.06% and 10.09%(P＜0.01) but the combined positive rate was not increased. In 100 healthy individuals from non-endemic areas, no positives were detected in serum and urine with false positive rate of 0%. The cross reaction rates in serum and urine of 51 cases with clonorchiasis were 9.43% and 0% but all were 0% in 48 cases with ancylostomiasis.
