Objective To investigate the characteristic and clinical value of echocardiography in pregnant women with sinus tachycardia.Methods Thirty pregnant women with sinus tachycardia (experiment group) and 30 healthy pregnant women (control group) were selected.The echocardiography results and clinical data were compared between the 2 groups.Results There were no statistical differences in age,gestational age,blood pressure,weight between the 2 groups (P ＞ 0.05).The heart rate in experiment group was significantly higher than that in control group [(123.20 ± 13.23) times/min vs.(86.17 ± 6.78) times/min],there was statistical difference (P ＜ 0.01).The left ventricular posterior wall thickness and the rates of mitral regurgitation,tricuspid regurgitation,aortic regurgitation in experiment group were significantly higher than those in control group [(10.23 ± 1.30) mm vs.(8.79 ± 1.90) mm,63.33％ (19/30) vs.16.67％ (5/30),66.67％(20/30) vs.30.00％(9/30),26.67％(8/30) vs.6.67％(2/30)],the left ventricular posterior wall motion amplitude was significantly lower than that in control group [(8.07 ± 1.00) mm vs.(9.26 ± 1.71) mm],there were statistical differences (P ＜ 0.01 or ＜ 0.05).There were statistical differences in the indexes of left ventricular systolic function and diastolic function between the 2 groups (P ＜0.01 or ＜0.05).Conclusion The anatomical indexes and function indexes of echocardiography in pregnant women with sinus tachycardia are used to change,and the echocardiography in time can provide the basis of treatment.

Objective To investigate the mechanisms of estrogen in the pathogenesis of systemic lupus erythematosus(SLE),we compared the effects of 17β-estradiol(E2)on bone marrow(BM)-derived dendritic cells (BMDCs)in(NZBxNZW)F1(NZB/w F1)female mice befbre and after the disease onset.Methods Immature,BMDCs were differentiated from BM monocytes cultured with rmGM-CSF,rmlL-4,E2 and estrogen receptor (ER)modulator-tamoxifen(TAM)for 7 days.Then immature DCs were stimulated by LPS for 24h to get mature BMDCs.Flow cytometry was utilized to detect the production of costimulatory molecule CD40 and intracellular IL-6,IL-10,IL-12 and TNFα of DCs.Mixed lymphocytes reaction was used to measure the stim-ulatory activity of DCs on spleen T lymphocytes.Results E2 mainly increased the expression of CD40 on im-mature BMDCs but reduced its expression on mature BMDCs.E2 enhanced the stimulatory activity of immature BMDCs,but weakened the activity of mature BMDCs.E2 decreased the production of cytokines of BMDCs in young mice,but increased them in old mice.Conclusion E2 modulates the functions of BMDCs of lupus model mice by binding with ER.The modulation varies depending on disease progression and cell maturation status.

Objective To investigate the effect of estrogen on dendritic cells (DCs) and its role in disease progression by comparing the effects of 17β-estradiol (E2) on spleen DCs in systemic lupus erythe matosus (SLE) murine modeI-(NZBxNZW) F1 (NZB/w F1 ) female mice before and after the disease onset.Methods Anti-CD11c antibody labeled magnetic bead was used to purify spleen DCs.Flow cytometry was utilized to detect the co-stimulatory molecules and intracellular cytokines of DCs.Mixed lymphocytes reaction (MLR) was used to measure the stimulatory activity of DCs to T iymphocytes.And semi-quantitative RT-PCR was employed to check the expression of estrogen receptor (ER).Results E2 could modulate the expression of surface molecule CD40,the production of cytokines IL-6,IL-10,IL-12 and TNFa,and the stimulatory a bility of spleen DCs in SLE model mice.Tamoxifen (TAM) could antagonize E2 effects and E2 could affect the estrogen receptor (ERα) level of DCs.These changes of DCs varied with age.Conclusion E2 may be in volved in the pathogenesis of SLE by modulating DCs by binding ERa.The effects of E2 vary in different stages of SLE progression.

BACKGROUND:There are less studies on static magnetic field, and its biological effects are stil unclear. OBJECTIVE:To investigate the static magnetic field effect on the secretion of nerve growth factor from Schwann cel s. METHODS:Schwann cel s were randomly assigned into three groups:0.05 mT sciatic magnetic field group, 0.1 mT sciatic magnetic field group and control group. At 2 days of inoculation, the cel s were exposed to the sciatic magnetic field, 12 hours per day. Cel s in the control group were not exposed to the sciatic magnetic field. After 6 days of exposure, RT-PCR method was used to detect nerve growth factor mRNA expression in Schwann cel s, and ELISA was adopted to detect the level of nerve growth factor secreted from Schwann cel s. RESULTS AND CONCLUSION:The mRNA expression and secreted level of nerve growth factors in the culture supernatant were significantly higher in the two sciatic magnetic field groups than the control group (P<0.05), especial y in the 0.1 mT group. However, there was no difference between the 0.05 mT and 0.1 mT groups (P>0.05). These findings indicate that the static magnetic field with certain intensity can promote the secretion of nerve growth factors from Schwann cel s.

Objective To explore the outcome and diagnostic methods of umbilical cord winds of the perinatal. Methods Retrospective analysis of 2350 cases of umbilical cord winds in our hospital was conducted. We selected 2400 cases as control. We calculated both the incidence rate of cesarean section, fetal distress and neonatal hypoxic - ischemic encephalopathy. Results Umbilical cord winds accounted for 20.1 percent of the total number of deliveries in the same period. The incidence rate of fetal distress and cesarean section was significantly high. Bsound ultra was 98.9% diagnosis. The electronic fetal care was 99.7% in diagnosis. Color Doppler ultrasound was 100% in diagnosis. Conclusion Umbilical cord winds is a common complication of pregnancy, and decision is also an important factor for delivery mode. Umbilical cord winds will increase obviously in the incidence of fetal distress and perinatal morbidity. The main method for prenatal diagnosis is the color Doppler ultrasound examination, such as B - and E - fetal care. Color Doppler ultrasound technique is the best way for non - invasive is observation of intrauterine blood circulation changes. In helpful for the judge of the progress and outcome of pregnancy, fetal growth and development of the situation.

Transgenic animals are those in which recombinant DNA technology is used to remove a gene or a specific part of DNA with exogenous DNA, which is hereditable and can be expressed stably. Transgenic rodent technology, first demonstrated by Gordon in 1980,opened the door to the next step in biotechnology and gene regulation, which has been used to reproduce or mimic a part of a human disease in a complex cellular environment by creating in vivo models with germ line transmission of the introduced genetic regulatory elements. Animal models for drug discovery are developing increasingly, which is promoting the research and development new drugs greatly. The use and development of transgenic animals in pharmacological research is reviewed in this article.
