OBJECTIVETo investigate the influences of mobile phone radiation on the quality and DNA methylation of human sperm in vitro.
METHODSAccording to the fifth edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen, we randomly selected 97 male volunteers with normal semen parameters and divided each semen sample from the subjects into two equal parts, one exposed to mobile phone radiation at 1950 M Hz, SAR3. 0 W/kg for 3 hours while the other left untreated as the control. We obtained routine semen parameters as well as the acrosomal reaction ability, apoptosis and DNA methylation of sperm, and compared them between the two groups.
RESULTSCompared with the control, the radiation group showed significantly decreased progressive sperm motility ([36.64 ± 16.93] vs [27.56 ± 16.92]%, P < 0.01) and sperm viability ([63.72 ± 16.35] vs [54.31 ± 17.35]%, P < 0.01) and increased sperm head defects ([69.92 ± 4.46] vs [71.17 ± 4.89]%, P < 0.05), but no significant differences in sperm acrosomal reaction ([66.20 ± 6.75] vs [64.50 ± 3.47]%, P > 0.05). The early apoptosis rate of sperm cells was remarkably higher in the radiation group ([6.89 ± 9.84]%) than in the control ([4.44 ± 5.89]%) (P < 0.05). However, no statistically significant differences were found between the control and radiation groups in the DNA methylation patterns of the paternal imprinting gene H19 ICR ([0.60 ± 0.02] vs [1.40 ± 0.03]%, P > 0.05) or the maternal imprinting gene KvDMR1 ([0.00 ± 0.00] vs [1.80 ± 0.031%, P > 0.05).
CONCLUSIONMobile phone radiation reduces the progressive motility and viability of human sperm and increases sperm head defects and early apoptosis of sperm cells.

Objective To assess the effect of ultrasound contrast agent SonoVue on the dimensions and systolic function of left and right ventricle in pigs. Methods Sixteen pigs were randomly assigned to two groups. Intravenous injection of 1 ml of SonoVue were given in study group, and repeated 20 min later. The control group was given the same doses of saline. Before and after the administration of contrast agent, the end-diastolic dimension (LVEDD, RVEDD). end-systolic dimension ( LVESD, RVESD) and fractional shortening(LVFS,RVFS) of left and right ventricle were measured. The time to reach the extreme value of these parameters and the time to return to the baseline were recorded. Results There was no significant difference regarding the parameters at baseline between the two groups. After injection of SonoVue,RVEDD significantly increased from (25. 88 ± 1. 38) mm at baseline to its maximum of (33. 26 ± 0. 99)mm( P < 0. 05). Accordingly,RVFS significantly increased from (26. 90 ± 1. 92) % to (33. 92 ± 2. 53) % ( P <0. 05). Meanwhile,LVEDD remarkably decreased from (38.10 ± 1. 39)mm at baseline to its minimum of (26.25 ± 0. 65)mm( P <0. 05) and LVFS remarkably decreased from (36. 24 ± 1. 93) % to (29.13 ± 3.00) % ( P < 0. 05). There was no change in the control group after administration of the saline. When SonoVue was given repeatedly, the maximum RVEDD and RVFS was (29. 98 ± 1. 23) mm and (31. 09 + 1.90) % , respectively, which had less increase compared to the first time. Minimum LVEDD and LVFS was (31. 91 ± 1, 64)mm and (32. 17 ± 2. 31)%,respectively,with less decrease compared with which at first injection. It took (10. 15±0. 59) min for the right and left ventricle to reach the extreme value and (9.00± 0. 56) min to return to the baseline at the first injection. The time used for the right and left ventricle to reach its peak change and back to baseline after second injection of SonoVue were shorter [(8.73± 0.55) min and (6.89± 0.43) min, respectively,both P <0.05]. Conclusions Administration of SonoVue was associated with acute, transient dilation of right ventricle and compression of left ventricle. The influence of SonoVue on the right and left ventricle became less at it second injection.

BACKGROUNDThe coagulation function in carcinoma patients is abnormal, but in renal cell carcinoma the extent and relationships of coagulation function remain unclear. This study retrospectively investigated the relationships between coagulation function, clinical stage and metastasis in patients with renal cell carcinoma.
METHODSA total of 350 consecutive patients admitted to our Urology Department from 2004 to 2010 were diagnosed with renal cell carcinoma by histopathologic examination and were included in this study. A total of 231 cases of renal benign tumors were considered as the control group. Fibrinogen, prothrombin time, activated partial thromboplastin time and international normalized ratio were evaluated in all subjects. Tumor size, clinical stage, lymph node metastasis, and distant metastasis were evaluated using radiologic imaging, intraoperative findings, and histological studies.
RESULTSThe preoperative plasma fibrinogen levels of patients with renal cell carcinoma ((383.9 ± 146.7) mg/dl) were significantly higher than those of the control group ((316.7 ± 62.0) mg/dl) (P < 0.01). We divided the renal cell carcinoma group into stages Ia, Ib, II, III, and IV. The fibrinogen values were (315.6 ± 64.6) mg/dl, (358.3 ± 91.1) mg/dl, (465.6 ± 164.7) mg/dl, (500.0 ± 202.1) mg/dl, and (585.8 ± 179.7) mg/dl, respectively. There were no significant differences in fibrinogen values between stage Ia and control groups. However, results of other stages showed significant differences when compared to control group values (P < 0.01). Using the cutoff value of 440 mg/dl, which defines hyperfibrinogenemia, plasma fibrinogen levels had a positive predictive value of 39.8% and a negative predictive value of 93.3% for predicting distant metastasis, with a sensitivity of 64.7% and specificity of 83.3%.
CONCLUSIONSPreoperative plasma fibrinogen levels are elevated in patients with renal cell carcinoma with distant metastasis or lymph node metastasis. Potential metastasis is more likely if the tumor size larger than 4 cm. Increased preoperative plasma fibrinogen levels, especially hyperfibrinogenemia, may be an indicator of metastasis.

OBJECTIVETo examine the effect of exposure to extremely low-frequency electromagnetic fields (ELF EMFs) on the liver function of workers.
METHODSThe workers in a factory were selected as subjects, and the recent physical examination data of these workers were collected. The workers aged 20∼40 years and with more than 2 years' working experience were included for analysis; considering the intensity of electromagnetic field, the workers exposed to less electromagnetic radiation were assigned to exposure I group (n = 123), those exposed to more electromagnetic radiation to exposure II group (n = 229), and those not exposed to electromagnetic radiation to control group (n = 212). There were no significant differences in sex, age, height, and body weight between the three groups (P > 0.05). Physical examination, including measurements of direct bilirubin (DBil), alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), and albumin, was performed in a health examination center. The intensity of electromagnetic field was measured by EFA-300 power frequency electromagnetic field analyzer, and the intensity of noise by AWA5610D integrating sound level meter.
RESULTSThe intensities of electric field and the magnetic field in exposure II group were significantly higher than those in the exposure I group. The levels of ALT, ALP, AST, GGT and albumin in exposure II group were significantly higher than those in exposure I group and control group. However, the level of direct bilirubin in exposure II group was significantly lower than that in exposure I group and control group.
CONCLUSIONOccupational exposure to ELF EMFs may affect human liver function.
