Thyroid hormones (TH) play an imp or tant role in the development and maturity of the mammalian brain. Maternal TH de ficiency, even subclinical hypothyroidism, leads to poor neurodevelopment of the fetus. Screening of pregnant women for hypothyroidism is recommended. Identific ation of the TH-responsive genes in the developing brain and investigation on t heir functions are helpful to provide insights into the molecular mechanisms by which TH influence brain development.

This paper introduces the nursing care for 36 patients with framework exposure in auricular reconstruction by temporal superficial fascia flaps combining with split skin grafts transplantation,such as pre-and post-operative behavioral in-struction,psychological care,and close observation of blood circulation of reconstructed auricular. The patients' wounds healed up well and all the split skin grafts survived successfully. No infection and stent exposure occurred once more. The appear-ance of the reconstructed auricular was pleasing too. It is suggested that high quality of pre-and post-operative nursing,care-ful health education and psychological care be beneficial for the successful repair of framework exposure after auricular recon-struction.

Objective To study the effect of hypothyroidism on oxidative stress status in developing rat brain and to further explore the mechanism of impaired brain development caused by hypothyroidism. Methods Perinatal hypothyroidism was induced by administering propylthiouracil(PTU) solution to the dams by gavage.The oxidative stress indexes were measured in brain homogenate of normal and hypothyroid pups which were sacrificed on the 21st d after birth. Results As compared to the control,the following indexes were found to be increased in the hypothyroid group: protein carbonyl contents,thiobarbital acid reactive substances,reduced glutathione,total antioxidative capacity,activities of superoxide dismutase and glutathione peroxidase(P0.05). Conclusion Hypothyroidism during rat brain development may cause oxidative stress,which may be related to the brain damage caused by hypothyroidism.

Objective To study the value of CT angiography(CTA) and three dimensional contrast enhanced magnetic resonance angiography(3D CE-MRA) in the diagnosis of arteriosclerotic occlusive disease (ASO) of lower limb and evaluate arterial stenosis. Methods Thirty-eight patients clinically suspected ASO were studied with CTA and3D CE-MRA,twenty-two patients underwent DSA at the same time. The degree of seriousness of the stenosis shown by various imaging techniques were analyzed respectively. Results Using the DSA images as the standard reference, the sensitivity and specificity of CTA were 97.3% ,99. 1%, and MRA both were 100.0% in detecting the segments occluded. With regard the detection of segments that had more than moderate stenosis ,the sensitivity and specificity of CT were 99.3% ,97.6% ,and MRA were 97.9% ,96.4%. The degree of seriousness of the stenosis shown by MRA was overestimated than CTA on the segments that had more than moderate stenosis(x2 =5.80,P ＜0. 05). Conclusion CTA and 3D CE-MRA were reliable method in diagnosis of ASO.

Objective To assess the feasibility of low voltage with CARE dose 4D computed tomography pul-monary angiography(CTPA)by using image quality and radiation dosage.Methods 92 patients with clinically sus-pected pulmonary embolism(BMI:20 ~30kg/m2)were randomly divided into two groups(group A:n =46,80kV;groups B:n =46,100kV),the male and female of group A were equal to the number.Image quality score(given blind-ly by two senior radiologists ranged from 1 to 5 points).The CT value and standard deviation(SD)were measured and recorded in common pulmonary artery trunk,the main right pulmonary arteries,right low lobar arteries,and erector muscle of spine,calculated the SNR of ROI.Average CT value,signal noise ratio(SNR),CTDIvol,DLP were com-pared between the two groups.Used the CT dose index(CTDIvol)to compare radiation dosage between group A female and male.Results The agent average CT value and SD in arteries in group A [(510.27 ±115.45)HU,(50.06 ± 11.67)HU respectively]were higher than those in group B[(413.32 ±100.38)HU,(35.12 ±11.94)HU respective-ly],there were significant differences between the two groups(t =10.367,8.892,all P =0.000),but the SNR of ROI was (12.36 ±3.90),which was lower than (14.03 ±4.46)in group B,there was significant difference between the two groups(t =-5.238,P =0.001 ).Image quality score of transverse ection(1mm)in group A was (4.20 ± 0.29),which was lower than (4.91 ±0.36)in group B,there was significant difference(t =-20.23,P =0.000), but there was no significant difference in coronal section(5mm),coronal maximum intensity project(MIP)image and the capability of displaying the pulmonary artery branches(all P >0.05 ).The CTDIvol in group A was (2.03 ± 0.39)mGy,which was greatly lower than (5.04 ±1.02)mGy in group B,there was significant difference (P <0.05);but there was no significant difference between female and male in group A[male:(2.05 ±0.39)mGy;female:(2.01 ±0.38)mGy,t =-0.300,P >0.05].Conclusion Radiation dose can be decreased greatly(above 50%)in 80kV CTPA compared 100kV without compressing obviously the image quality for patients BMI 20 -30kg/m2 ,and no significant difference between the group A(80kV)different gender radiation dosage.

OBJECTIVE:To investigate clinical efficacy and safety of goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing levonorgestrel intrauterine system (LIS). METHODS:A total of 140 adenomyosis pa-tients with severe dysmenorrheal were selected from Sanya Family Planning Technology Service Center during Jan. 2014-Jan. 2016, and then divided into control group and observation group according to lottery method,with 70 cases in each group. Both groups re-ceived LIS within first 7 d of menstruation,and observation group was given Goserelin acetate sustained-release implant 10.8 mg subcutaneously via anterior abdominal wall one week before placing. Therapeutic efficacy was evaluated 6 months later. The im-provement of dysmenorrhea was compared between 2 groups. The uterine volume,COX dysmenorrhea score (CMSS),menstrual volume,hemoglobin (Hb) and CA125 content were compared between 2 groups before and after treatment. The occurrence of ADR was also compared. RESULTS:The rate of dysmenorrheal improvement in observation group was 95.71％,which was signifi-cantly higher than 81.43％of control group,with statistical significance(P<0.05). Before treatment,there was no statistical signif-icance in above indexes between 2 groups (P>0.05). Compare to before treatment,CMSS score,menstrual volume and CA125 content of 2 groups were decreased significantly after treatment,while Hb content was increased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in uterine volume between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR(10.00％ vs. 14.29％)between 2 groups(P>0.05). CONCLUSIONS:Goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing LIS can effectively relieve dysmenorrheal,reduce menstrual volume and improve Hb and CA125 levels,but do not increase the risk of ADR.

Objective To investigate the effect of triiodothyronine on the expression of alpha subunit of C protein Co (Coa) gene in cultured rat cerebral cortex neurons. Methods Primary cultured neurons of rat were prepared from the cerebral cortex at embryonic day 19. The neurons were cultured in DMEM supplemented with 15% fetal calf serum. After 7 days, the neurons were cultured in different media; DMEM supplemented with 15% fetal calf serum (group A), DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group B), 0.5nmol/L T3-containing DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group C) , 5nmol/L T3-containing DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group D) and 50nmol/L T3-containing DMEM supplemented with 15% fetal calf serum stripped of thyroid hormone (group E). The neurons were cultured for another 7 days and total RNA was extracted. Goa mRNA leves were measured by competitive RT-PCR. Results As compared with group A, Coa mRNA leves in group B, D and E were low (P 0.05). Conclusion T, has dual effects on the expression of Coa gene in cultured rat cerebral cortex neurons. T3 down-regulated Coa mRNA in cultured neuron. However, in the absence of T3, Goa mRNA was also very low. Thyroid hormone may exert their action on brain development by regulating the the expression of Goa gene.

This study was aimed to establish a method for assay of 4-terpineol, α-terpineol, bornyl acetate and methyl-n-nonylketone in Houttuynia cordata with gas chromatography-mass spectrometry (GS/MS) for the first time in order to provide experimental evidences for its quality control. Undecylen was analyzed quantitatively. GC/MS method was used in the content determination of 4 kinds of components in Houttuynia cordata. GC conditions were that the temperature was firstly increased to 70oC for 5 min, and then 5oC·min-1 to 140oC for 5 min. Then, the temperature was increased by 10oC·min-1 to 250oC for 10 min. The temperature of the injection port was 230oC. The carrier gas was high purity helium. The flow rate was 1.0 mL·min-1. The split ratio was 10:1. The sample quantity was 1 μl. MS conditions were that the detector was MS, EI was 70ev, the temperature of four poles was 150oC, the temperature of ion source was 230oC. The results showed that there was good linearity of four components, which were 4-terpineol, α-terpineol, bornyl acetate and methyl-n-nonylketone obtained within the ranges of 6.492~129.84μg·min-1, 1.097~21.944 μg·min-1, 12.128~242.56 μg·min-1, and 84.76~169.52 μg·min-1, respectively. The average recoveries of the four components were 81.2%, 80.6%, 88.3%, and 84.6%, respectively. The RSDs were 1.5%, 2.3%, 1.1%, and 0.7%, respectively. It was concluded that the method was simple, sensitive, and easy to operate. The simultaneous measurement of multiple indexes on the component for quality evaluation of Houttuynia cordata can effectively reflect the quality of Houttuynia cordata. It can also be used in the quality assessment of fresh Houttuynia c ordate .
