We determined estrogen receptor (ER), estradiol (E2) and testosterone (T) in the tissue of 50 gastric carcinomas ans 20 benign stomach diseases. The result showed that the positive rate of ER was 32.0% in gastric cancerous tissue, in which the poorly-differentiated type was higher than that of the well-differentiated type (Plt;0.05)，and still higher in BorrmannⅢ、Ⅳ types than in Borrmann Ⅰ、Ⅱ types (Plt;0.01). The determination of Er is significant for the estimation of prognosis ans endocrinal therapy after operation. E2 content showed no obvious difference betweenn gastric carcinoma, benign somach diseases ans normal gastric mucose, but T level and T/E2 ratio in gastric cancer were much higher than those in benign stomach diseases and normal gastric mucosa (Plt;0.05). IT suggested that the imbalance of E2 and T contents may related the occurence of gatric carcinoma. The E2 and T level showed no obvious difference between ER+ and ER- in gastric cancerous tissue.
Objective To investigate the relationship between the level of testosterone and estradiol in serum and central serous chorioretinopathy (CSC).Methods The clinical data of 200 patients with active phase CSC who diagnosed by clinical manifestation, examination of fundus and fluorescence fundus angiography (FFA), were retrospectively analyzed. Two hundreds healthy people were collected as a control group. The blood of ulnar vein was collected and the method of magnetic homogeneous enzyme immunoassay was used to detect the level of testosterone and estradiol in serum of two groups. The results were analyzed statistically by t test.Results The values of testosterone and estradiol of male were all higher in CSC group than that in control group，the differences were statistical significance（t=2.804，2.913；P=0.010，0.008）；it was also higher in female（t=2.078，2.807；P=0.049，0.010）. The value of testosterone/estradiol of male was higher than that of female in CSC group，the difference was statistical significance(t=2.231，P=0.046).Conclusions The level of testosterone and estradiol in serum of CSC group increased obviously, especially the value of testosterone/estradiol. The increase of estradiol and testosterone/estradiol may be an etiological factor of CSC.
Objective To evaluate the efficacy and safety of testosterone supplementary treatment for the middle-aged and the senile with insulin resistance (IR). Methods Such databases as PubMed (Jan. 1966 to July 2010), EMbase (Jan. 1984 to July 2010), The Cochrane Library (Issue 3, 2010), CBM (1978 to July 2010), CNKI (Jan. 1994 to July 2010), WanFang Data (1994 to July 2010) and VIP Data (1989 to July 2010) were searched. Randomized controlled trials (RCTs) about testosterone treatment for IR were included. Two reviewers independently extracted the data and evaluated the quality of the included studies. Meta-analyses were performed for the results of homogeneous studies by using RevMan 5.0 software, and other results not suitable for meta-analysis were described with qualitative analyses. Results Nine RCTs involving 573 patients were included. Of them, 308 cases were in the testosterone group and 265 in the placebo group. The baseline data of studies was comparable. The results of meta-analyses showed that, a) Efficacy: testosterone was superior to placebo in decreasing insulin resistance index (HOMA-IR) (WMD= –?0.56, 95%CI –?0.75 to –?0.37) and fasting insulin (FINS) (WMD= –2.4, 95%CI –3.25 to –1.56); and b) Safety: no significant difference was found in prostate specific antigen (PSA) (WMD= –?0.02, 95%CI –?0.22 to 0.18). Conclusion The testosterone supplementary treatment for insulin resistance is superior to the placebo, and there is no significant difference in PSA compared to the placebo. More multicenter double-blind RCTs in large-scale are required to verify this conclusion because of lack of high quality literature with large sample size.
Objective To study the effectiveness, safety and tolerance of testosterone undecanoate （TU） in improving exhaustion and quality of life （QOL） of the elderly male patients with chronic disease in advanced stage. Methods Using a simple randomized controlled trial design, eighty patients were randomized into two groups. The treatment group took routine therapy and TU and the control group with routine therapy alone. Results 1. Baseline characteristics in both groups were similar. 2. The PADAM grade decreased, and the QOL scale increased in the treatment group （P〈0.05 ）. 3. Serum total testosterone in the treatment group rose, upper arm circumference and right hand grip improved （P〈0.05 ）. 4. There were no significant differences in adverse effects between both groups. Conclusions TU can improve the clinical health status in the elderly male patients with chronic disease in advanced stage and increase serum testosterone level, there is a satisfactory tolerances and few adverse reactions.
Objective To ananlyze the relationship between bone mineral density and sex hormone in male patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods The study recruited 88 male patients with OSAHS aged 45-60 years in our hospital from October 2014 to October 2016 as an OSAHS group, and 30 healthy subjects without OSAHS as a control group. The general information and PSG parameters were recorded, the bone metabolic markers and bone mineral density of lumbar spine 1-4 (L1-4) and femoral neck (Neck) were measured, and the expressions of serum sex hormone (E2, P, T, FSH, LH and PRL) were determined by chemical luminescence immunity analyzer. The differences in above indexes between two groups and their correlation with bone mineral density were analyzed. Results Smoking rate, drinking rate, neck circumference and body mass index (BMI) of the OSAHS group were significantly higher than those of the control group. Compared with the control group, beta crosslaps (β-CTX, a bone metabolic marker) was significantly higher [(0.53±0.14) ng/ml vs. (0.47±0.15) ng/ml], the bone mineral density of L1-4 and Neck was significantly lower [(0.92±0.12) g/cm2 vs. (1.08±0.08) g/cm2, (0.91±0.11) g/cm2 vs. (1.06±0.13) g/cm2], and the serum testosterone was significantly lower in the OSAHS group [(267.32±89.56) ng/dlvs. (315.68±78.49) ng/dl] (all P<0.05). The result of Pearson correlation analysis showed that apnea hypopnea index (AHI) was negatively correlated with bone mineral density of L1-4 and Neck (bothP<0.001), lowest oxygen saturation (LSaO2) and testosterone were positively correlated with bone mineral density of L1-4 and Neck (all P<0.01). Conclusions The risk of suffering from osteoporosis is higher in male OSAHS patients and it is closely related to the degree of hypoxia. The decrease of testosterone may be one of the mechanisms.
