ABSTRACT
Objective We studied the EHD2 expression level in NSCLC and its association with clinicopathological features and prognosis.Methods The EHD2 expression level in NSCLC was measured by Western blot in 4 pairs fresh tissues and immunohistochemistry on 91 parffin-embedded slices.These experiments were used to explore the relationship of EHD2 and Ki-67 in the clinical parameters,as well as the relationship with EHD2 and prognosis.Results Western blot showed EHD2 expression level was low in 4 pairs NSCLC tissues.The results by immunohistochemistry showed that the expression of EHD2 was higher in well-differentiated NSCLC tissues than that in poor-differentiated tissues,which was opposite to the Ki-67 expression.Statistical methods revealed that EHD2 protein in NSCLC was significantly correlated with histological grade,pTNM staging,tumor size,lymph node metastasis as well as Ki-67.Low EHD2 expression was correlated with poor prognosis.Conclusions The abnormal expression of EHD2 might be closely related to the initiation and progress of NSCLC.EHD2 might be an indicator of the prognosis of NSCLC,which could be a potential target for NSCLC therapy.

ABSTRACT
<p><b>BACKGROUND</b>Depot medroxyprogesterone acetate (DMPA) as a hormonal contraceptive is highly effective and widely used, but it may reduce bone mineral density (BMD) and increase the risk of osteoporosis. We compared BMD between users of intramuscular DMPA and nonhormonal subjects.</p><p><b>METHODS</b>The study included 102 women aged between 16 and 18 years using DMPA for 24 months and 97 women aged between 16 and 18 years using nonhormonal contraception as nonusers control group. BMD of the lumbar spine and femoral neck was measured every 12 months for 24 months using dual-energy X-ray absorptiometry, comparing mean BMD changes in DMPA users and nonusers.</p><p><b>RESULTS</b>There were no significant differences between groups at baseline in age, gynecologic age, body mass index (BMI), lumbar spine BMD and femoral neck BMD, etc. At 24 months of DMPA treatment, the mean percentage change from baseline in lumbar spine and femoral neck BMD values had decreased by 1.88% and 2.32%, respectively. The mean lumbar spine and femoral neck BMD in DMPA group at 24 months were not significantly different compared to baseline (P = 0.212 and P = 0.106, respectively). In comparison, in nonhormonal control group, there was a trend toward increasing BMD. At 24 months of observation, the mean percentage change from baseline in lumbar spine and femoral neck BMD had increased by 2.08% and 1.46%, respectively. There were no significant difference compared to baseline (P = 0.160 and P = 0.288, respectively). Mean BMD at the spine and femoral neck did not differ significantly between DMPA users and nonusers over 12-month, but the BMD values at both anatomical sites were significantly lower in DMPA users compared with nonusers after 24-month treatment (P = 0.009 and P = 0.009, respectively).</p><p><b>CONCLUSION</b>The evidence of our study suggested that the use of DMPA for short-term (≤12-month) has no significant effects on BMD at spine and femoral neck, but long-term exposure to DMPA may prevent the bone mass accrual in adolescents.</p>

Objective To determine the effect of high-intensity physical activity on bone mineral density(BMD). Methods Thirty-six female soccer players (19.56±1.46 years) with more than two years training history and at least ten months soccer training annually were recruited as experiment group. Thirty-three female sedentary college students, whose physical activities were limited to the compulsory physical education curriculum,were assigned to the control group. BMD of lumbar spine and femoral neck were obtained before and after 24 months research,using dual energy X-ray absorptiometry. Results After 24 months research, increased BMD were found in both groups. Soccer players had 2.25% increase of lumbar spine BMD(P0.05) and 2.03% increase of femoral neck BMD(P>0.05). Compared with sedentary college students,Lumbar spine and femoral neck BMD in soccer players were significantly higher(P<0.05) after 24 months research. Conclusion Long-term soccer training had the effect of greater acquisition of BMD.
ABSTRACT
<p><b>OBJECTIVES</b>The investigation of the testicular volume, the penis length and the T, FSH, LH, PRL levels in serum were taken in 289 adolescent males to provide the valuable data for andrology.</p><p><b>METHODS</b>The adolescent males were grouped according to their age. The testicular volume was measured with testicular model and the T, FSH, LH, PRL levels in serum were determined by immunoenzymetric assay.</p><p><b>RESULTS</b>The male sexual development was rapid from age 11 to 16 and close to that of adult at age 18. Serum PRL of adolescent males was higher than that of adult males.</p><p><b>CONCLUSIONS</b>The age 11 to 16 is a period of rapid growth in sexual maturation. PRL may play an important role in sexual maturation.</p>
