The level of androgen receptor (AR), estrogen receptor (ER) and progesterone receptor (PR) of carcinoma and pericarcinoma tissue were determined in 30 cases of male hepatocellular carcinoma (HCC) patients operated by streptavidin peroxdase conjugated method, meanwhile used 20 patients with benign liver disease as a contrast group. The results showed that the positive rate of AR in tumor tisse was 80.0%, significantly higher than that in peritumor tissue (46.7%) and liver tissue of benign diseases (40.0%), Ｐ＜0.01, and there was no significantly difference between the latter two groups (Ｐ＞0.05). The positive rate of ER in carcinoma tissue (43.3%) was notably lower than that in pericarcinoma tissue (80.0%), Ｐ＜0.01. Statistically significantly difference wasn’t achieved in contrast with the benign diseases group (50.0%), Ｐ＞0.05. The positive rate of PR had no significantly difference among the three groups (Ｐ＞0.05). The authors suggest that sex hormone is related to initializing and developing of HCC by the action via its receptor, the level of AR and ER can be used as a prognosis determine index of HCC.
OBJECTIVE: To explore the effects of nandrolone phenylpropionate (NP) on the expression level of pro alpha 1 (I) collagen after burn in rats and the possible mechanism involved in the process. METHODS: Thirty-two Wistar rats with a deep second-degree scald injury and 20% of total body surface area were randomly divided into two groups to receive either 5 mg/kg NP(NP group) or normal saline (control group) every other day. We analyzed the mean integrated optical density(mIOD) of androgen receptor (AR) to determine the distribution and expression of AR in fibroblasts by immunohistochemistry, and measured expression level of pro alpha 1 (I) collagen mRNA by quantitative fluorescent RT-PCR to find the relation between expressions of AR and pro alpha 1 (I) collagen mRNA. The total specimens were obtained from the scalded rats after 4, 7, 14 and 21 of after burn. RESULTS: The expression of pro alpha 1 (I) collagen mRNA in NP group was significantly higher than that in control group on the 7th, 14th and 21st days(P lt; 0.05), but there was no significant difference on the 4th day. The density of AR in fibroblasts had significant difference (P lt; 0.05) between the two groups after 4, 7, 14 and 21 days. A positive relationship existed between the expression of pro alpha 1 (I) collagen mRNA and quantity of AR in fibroblasts(r = 0.836). CONCLUSION: The nandrolone phenylpropionate increased the expression of pro alpha 1 (I) collagen mRNA and enhanced the density of AR in fibroblasts. The higher expression of pro alpha 1 (I) collagen mRNA had a relation with the change of quantity of AR in fibroblasts.
Objective To investigate the effect of epristeride on 5-alpha-reductase activity and androgen receptor levels in prostate tissue. Methods Forty patients with benign prostate hyperplasia were randomly divided into the trial group and the control group with 20 in each group. Patients in the trial group were administered oral epristeride and terazosin, while those in the control group were given just terazosin. All patients underwent trans-urethral resection of the prostate after two weeks, and then the 40 samples of prostate were tested immunohistochemically for 5-alpha-reductase activities and androgen receptor levels. Results The 5-alpha-reductase in prostate tissue was not stained or lightly stained in the trial group, while it was heavily stained in the control group. The androgen receptor in prostate tissue was heavily stained in both groups. Conclusion Oral epristeride can inhibit the activity of 5-alpha-redutase in prostate tissue, but it has no obvious effect on the androgen receptor level in prostate tissue.
Objective To study the mechanism of nandrolone phenylpropionate (NP) on hepatic albumin mRNA and androgen receptor(AR) in burned rats. Methods Thirty-two Wistar rats with a deep second-degree cutaneous burn of 20% total body surface area were randomly divided into two groups:NP group (experimental group, 5 mg/kg NP) and normal saline as control group every other day. The expression copy quantity of albumin-mRNA and mean integrated absorbency(mIA) of AR in liver tissue were measured by quantitative fluorescent RT-PCR and immunohistochemistry respectively on the 4th, 7 th, 14th and 21st days of post-burned. Result The expression levels of ablumin-mRNA and AR in liver tissue in HP grouop were much higher than those in control group. The ablumin-mRNA and AR expression increased significantly(P lt; 0.05) after 7 and 14 days, whole the expression had no significant difference between NP group and control group on the 4th day. A positive correlation occurred between the expression level of albumin-mRNA and the quantity of AR in liver tissue(r=0.936, P lt; 0.05). Conclusion Nadrolone phenylpropionate up-regulated respectively the expression of albumin-mRNA and the density of AR in liver tissue.
Objective To investigate relationship between androgen receptor (AR) and clinicopathologic features of patients with triple negative breast cancer (TNBC) in Xinjiang. Methods The clinical data of Han and Uygur patients with TNBC from the First Affiliated Hospital of Xinjiang Medical University from December 2012 to December 2016 were retrospectively analyzed. And the expression of the AR and the clinicopathologic features of the patients with TNBC were extracted. The results were analyzed by SPSS 19.0. Results A total of 178 patients with TNBC were included, including 127 Han and 51 Uygur patients. The positive rate of the AR expression in the 178 patients with TNBC was 21.3% (38/178), which was significantly related to the expression of Ki-67 (χ2=15.196, P<0.001), was not related to the ethnicity (χ2=0.203, P=0.688), age (χ2=0.221, P=0.715), tumor size (χ2=0.047, P=0.855), lymph node status (χ2=0.874, P=0.354), or histological grade (χ2=0.001, P=1.000). And there were no statistically significant differences in the clinicopathologic features between the Han patients with TNBC and the Uygur patients with TNBC. Conclusion AR positive expression is related to Ki-67, but clinicopathologic features have no significant differences between Han and Uygur patients with TNBC in Xingjinag.
Objective To assess the clinical effectiveness and safety of astragalus injection plus androgen versus androgen alone for patients with aplastic anemia (AA). Methods Such databases as The Cochrane Library (Issue 3, 2011), PubMed (1966 to March 2011), EMbase (1974 to March 2011), CNKI (1994 to March 2011), VIP (1989 to March 2011) and Wanfang Data (1997 to March 2011) were searched to include the randomized controlled trails (RCTs) according to the inclusive and exclusive criteria. The data were extracted, the quality was assessed, and meta-analysis was conducted by using Revman5.0.24 software. Results Seven RCTs involving 518 patients with AA were included. The meta-analysis showed that the astragalus plus androgen treatment group was superior to the androgen alone group in the total effective rate with significant difference (OR=3.12, 95%CI 2.09 to 4.66, Plt;0.000 01); the adverse events in the treatment group were fewer than those in the control group with significant difference (OR=0.30, 95%CI 0.12 to 0.76, P=0.01); but the promotion degree of myelosis between the two groups was similar without significant difference (OR=1.93, 95%CI 0.85 to 4.38, P=0.11). Conclusion The astragalus plus androgen treatment is superior to the androgen alone treatment in the total effective rate and fewer adverse events. More high-quality trails are required to verify this conclusion due to the low quality and small scale of the included studies.
