ABSTRACT
Objective@#To investigate the expressions of glutathione S-transferase (GSTP1) and tetra-hydroxynonenal (4-HNE) in prostate cancer (PCa) and their clinical significance.@*METHODS@#We determined the expressions of GSTP1 and 4-HNE in 40 patients with PCa and another 42 with benign prostatic hyperplasia (BPH) by immunohistochemistry and analyzed their relationship with Gleason grades.@*RESULTS@#The expression rate of GSTP1 was 92.9% in the BPH tissue, and those in the highly, moderately, and lowly differentiated PCa tissues were 58.3%, 20.0%, and 16.7%, respectively, significantly higher in the BPH than in the PCa group (P <0.01). However, the positive rate of 4-HNE was only 5.0% in the BPH tissue, markedly lower than 91.6%, 100.0%, and 100.0% in the highly, moderately, and lowly differentiated PCa tissues (P <0.01). There was a negative correlation between the expression of GSTP1 and that of 4-HNE in the PCa tissue (r = －2.73, P <0.01).@*CONCLUSIONS@#Expression deletion of GSTP1 and high expression of 4-HNE may play an important role in the progression of prostate cancer.

<p><b>OBJECTIVE</b>To evaluate the therapeutic effect of Yinchenghao decoction (YCHD) and S-adenosy-L-methionine (SAM) in treating intrahepatic cholestasis of pregnancy (ICP) and improving prognosis of perinatal newborn babies.</p><p><b>METHODS</b>Sixty in-patients of ICP were randomly divided into two groups, the group A treated with YCHD and the group B treated with SAM. The symptom of itching and serum biochemical indexes, including glycocholic acid, bilirubin and transaminase, were observed after 3 weeks treatment, and the prognosis of perinatal newborn babies between the two groups was compared after delivery.</p><p><b>RESULTS</b>After treatment, the symptom of itching, serum levels of glycocholic acid, bilirubin and transaminase improved significantly (P < 0.05) in both groups, and the prognosis of newborn in the two groups was similar (P > 0.05).</p><p><b>CONCLUSION</b>Both YCHD and SAM could effectively treat ICP. The former is rather cheaper, so it is more feasible for spreading.</p>
