Objective To observe the effect of S-band micro-wave long-term intermittent irradiation on endocrine function in rats.Methods A total of 192 rats (male and female) were randomly divided into the sham-irradiation (normal control) groups and the irradiation groups.The irradiation groups were exposed with micro-wave at 3 dosages of 4,10 and 20 mW/cm2 for 6 min twice a week for 12 weeks,while no administration was given to control group.The endocrine parameters in blood serum were examined by radioimmunoassay at 4,8,12 week during irradiation and 4 week post-irradiation.Results After the irradiation of S-band microwave,parts of the endocrine parameters changed.T3 in famale rats decreased at first and then increased,especially in 10 mW/cm2 group at 8 and 12 week,20 mW/cm2 group at 4 and 12week(t =-2.586,-2.642,-5.075,-4.365,P <0.05).FT3 in famale rats had the similar trend asT3,significantly lower in 4 and 10 mW/cm2 groups than that in the control group at 4 week (t = 2.275,2.510,P <0.05),then increased,especially in three irradiation groups at 12 week (t =-2.636,-2.851,-5.240,P < 0.05).TSH decreased at 4 week,especially in 10 mW/cm2 group (t = 2.300,P < 0.05) ; and then increased in the irradiation groups at 20 mW/cm2 at 8 and 12 week (t =-2.838,-3.651,P <0.05).COR and ACTH in male rats showed changes in volatility,in which the 4,10 and 20 mW/cm2 groups at 8 week increased significantly (t =-2.772,-2.234,-2.505,P < 0.05),while 20 mW/cm2 group at 12 week decreased significantly (t=3.067,P < 0.05).E2 in female rats was slightly lower in irradiation groups at 4 week than the control group,then increased,especially in 10 mW/cm2 group at 8 week,three irradiation groups at 12 week (t =-2.322,-3.179,-2.655,-4.716,P < 0.05),and returned to the normal at 4 week post-irradiation,significantly lower in 4 mW/cm2 group than that in the control group (t = 2.250,P < 0.05).T in male rats increased first and then decreased,especially in 10 mW/cm2 group at 8 week(t =-2.435,P < 0.05).After exposure the above indexes restored to some extent.Conclusions The long-term intermittent irradiation of S-band microwave can cause adverse effects on the endocrine function of rats.

Objective To search for the most appropriate subzero nonfreezing temperature,and explore the effect of subzero nonfreezing preservation of rat kidney by comparing with the kidney preservation with conventional temperature (4 ℃,0 ℃) and freezing temperature (-4 ℃).Method The thermocouple probeand the temperature data logging device were used to detect the temperature decreasing curves in different parts of the rat kidney and determine the freezing point of the kidney.The perfused kidneys in rats were removed and put into the sterile tubes containing 2.5 mL hypertonic citrate adenine.Following 6 group were set up:-0.8 ℃ group (subzero nonfreezing),-0.5 ℃group (subzero nonfreezing),0 ℃ group (zero nonfreezing),-4 ℃ group (control group),-1 ℃group(subzero freezing)、-4 ℃ group (subzero freezing).After the cryopreservation for 24 and 48 h,the preservative fluid was harvested for measurement of the contents of LDH and AST,and the paraffin sections from the upper pole of the kidney were made for observation of the pathological changes and apoptosis.Result The freezing temperature of kidney was-1℃ and the most appropriate subzero nonfreezing temperature for preserving the rat kidney was-0.8 ℃.Subzero nonfreezing significantly inhibited the basal metabolic rate of the histiocytes,reduced the contents of LDH and AST released due to the membrane damage,and decreased the apoptosis rate [48 h:-0.8 ℃ (40.1 ± 7.0) ％ vs.4 ℃ (47.1 ± 7.6) ％].Under the light microscope after preservation for 48 h,the pathological changes in-0.8 ℃ group were less than in 4 ℃ group.Conclusion Compared with the organ preservation in conventional temperature (0 ℃-4 ℃),the subzero nonfreezing (-0.8 ℃) can further inhibit the basal metabolic rate of histocytes obviously,reduce its energy consumption,and lower the apoptosis caused by low temperature damage.

Specific scAbs could be obtained through biopanning from phage antibody libraries by use of antigens as target molecules. scAbs specific to thrombin were separated from mouse antibody library by the panning strategy of alternating liquid-solid phase in this paper. Thrombin was biotinylated by photobiotin at first, then avidin-coated magnetic beads were utilized to isolate specific scAbs. The eluted phages were amplified and subject to the second round panning in microtiter plate to remove the unspecific reombinant phages. 4 specific scAbs were separated from 23 phage clones after four rounds of alternative panning.

Objective To explore the impact of iodine nutrition on pregnant women before and after adjusting the iodine content in iodine salt.Methods Twelve counties (areas,cities) in Hangzhou were divided into urban,suburban and rural areas before and after adjusting the iodine content of salt.One survey spot was selected in each district and one hundred pregnant women were selected;family salt and urinary samples of each pregnant woman were collected.The levels of salt and urinary iodine were measured by the methods of picric sodium thiosulfate titrimetric (GB 13025.7-2012) and spectrophotometer (WS/T 107-2006),respectively.Results One thousand two hundred and thirty-nine and one thousand two hundred and thirty-three household salt samples were collected before and after adjusting the iodine content in iodine salt.The median of salt iodine of pregnant women (23.30 mg/kg) before adjusting the iodine content in iodine salt was lower than that after adjusting the iodine content in iodine salt (30.09 mg/kg,x2 =-4.71,P ＜ 0.01).The iodine salt coverage rate and the consumption rate of qualified iodized salt after adjusting the iodine content in iodine salt [93.92％ (1 158/1 233),93.84％ (1 157/1 233)] were higher than those before adjusting the iodine content in iodine salt [91.85％ (1 138/1 239),91.37％ (1 132/1 239),x2 =4.01,5.51,all P ＜ 0.05].The iodine salt coverage rate and the consumption rate of qualified iodized salt in urban and suburb areas after adjusting the iodine content in iodine salt [99.42％ (510/513),100.00％ (203/203),97.86％ (5021513),100.00％ (203/203)] were higher than those before adjusting the iodine content in iodine salt [86.71％ (450/519),98.00％ (196/200),77.26％ (401/519),85.00％ (170/200)],but the iodine salt coverage rate and the consumption rate of qualified iodized salt in rural area before adjusting the iodine content in iodine salt [94.62％ (492/520),86.92％ (452/520)] were higher than those after adjusting the iodine content in iodine salt [85.69％(443/517),76.98％ (398/517),x2=64.22,2.32,100.02,32.90,23.31,17.33,all P ＜ 0.05].One thousand two hundred and thirty-four and one thousand two hundred and thirty-one household urine samples were collected before and after adjusting the iodine content in iodine salt.The median of urinary iodine (MUI,114.80 μg/L) of pregnant women after adjusting the iodine content in iodine salt was lower than that before adjusting the iodine content in iodine salt (168.60 μg/L,x2 =36.92,P ＜ 0.01).The MUIs of pregnant women in urban,suburban,and rural areas (171.30,170.20 and 162.40 μg/L) before adjusting the iodine content in iodine salt were higher than those after adjusting the iodine content in iodine salt (101.00,149.48 and 119.90 μg/L,x2 =-7.78,-2.63,-6.28,all P ＜ 0.01).The differences of urinary iodine between groups were statistically significant in urban,suburban and rural areas after adjusting the iodine content in iodine salt (x2 =32.86,P ＜ 0.01),the MUI of pregnant women in urban areas was lower than those in the suburban and rural areas (x2 =6.70,8.13,all P ＜ 0.05).Conclusions After adjusting the iodine content of salt in Hangzhou,the iodine-nutrition level of pregnant women is decreased.But the consumption rates of qualified iodized salt and the MUIs in urban,suburb,rural areas are different,so the coverage of iodized salt at household level needs to be enhanced and the health education should be highlighted.
