Objective To evaluate the association between maternal thyroid diseases in the first trimester of pregnancy and obstetric complications.Methods A total of 2 517 pregnant women from 10 hospitals in Shenyang during the first 12 weeks of gestation were enrolled in this study.All sera obtained from pregnant women were measured for thyroid-stimulating hormone (TSH),free thyroxine ( FT4 ),and thyroid peroxidase antibody (TPOAb).Collected items include obstetric outcomes and complications.Results Serum TSH above 2.5 mlU/L during the first trimester of pregnancy increased the rate of spontaneous abortion ( 8.69% vs 6.38%,P =0.048 ),even if subclinical hypothyroidism (9.50% vs 6.38%,P =0.009).TSH above the gestational special reference range,passive smoking,and over 30 years were independent factors for increasing the rate of spontaneous abortion.Hyperthyroidism and hypothyroidism with drug treatment to maintain normal thyroid function during pregnancy reduced the incidence of spontaneous abortion.Increased or decreased levels of serum TSH and TPOAb(+) were not related with other obstetric complications.Conclusion Serum TSH above the gestational special reference range during the first trimester of pregnancy is a risk factor of spontaneous abortion; maintaining TSH within the normal range by treating hyperthyroidism or hypothyroidism may reduce spontaneous abortion rate.

Objective To investigate changes of the elastic modulus of astrocytes induced by injury. Methods The astrocytes were isolated and extracted from the 2-day old SD rats, and identified by immunofluorescence staining with glial fiber acidic protein (GFAP) antibody. Cells were divided into control group and injured group. The injured group was astrocytes 6 h after being injured by the cell damage instrument. The control group was astrocytes without any injury. The elastic modulus in liquid phase was tested by atomic force microscope in two groups. Results were compared and analyzed between two groups. Results The purification rate of rat astrocytes was more than 95%. Six hours after the injury, the astrocytes were in disorder, and some of cell bodies were swelling. The mechanical topographic maps and force indentation curves were obtained. The elastic modulus of astrocytes was significantly increased in injured group compared with that of control group[(1 689±693) Pa vs. (724±283) Pa, P<0.01]. Conclusion The injury stimulus increases the elastic modulus of astrocytes, which provides theoretical basis for understanding intracranial physical microenvironment after traumatic brain injury in animal experiments.
