Objective to analyze the relation between glycosylated hemoglobin (HbA1c) of pregnant women with gestational diabetes mellitus (GDM) and neonatal blood glucose.Methods HbA1c values of 743 pregnant women with GDM are detected,and according to HbA1c level,they were divided into 3 groups,such as G1 (HbA1c＜5.5％),G2 (5.5％≤HbA1c≤6.5％) and G3 (HbA1c＞6.5％).Newborn babies' blood glucose values of the women in each group are monitored respectively in the 1st hour and at the 4th and 8th hour.Neonatal hypoglycemia and incidence of threshold blood glucose in the three groups are compared by SPSS 17.0 software.Results (1) The incidence of neonatal hypoglycemia in G1 and G2 are both higher than thatin G3 in the 1st hour (P＜0.05).The incidence of neonatal hypoglycemia in G3 is higher than that in G1 and G2 at the 4th and 8th hour (P＜0.05).(2) With time extending,the incidence of neonatal hypoglycemia declines in G1 and G2 (P＜0.05),but there is no obvious decline in G3 (P＞0.05).(3)The incidence of threshold blood glucose in G3 and G2 are higher than that in G1 in the 1st hour,and at the 4th,8th hour(P＜0.05),and there is no obvious statistical difference between G2 and G3 (P＞0.05).(4)With time extending,the incidence of threshold blood glucose declines in G1 (P＜0.05),but it doesn't decline in G3 evidently(P＞0.05).And there was no obvious decline in G2 in the 4 hours after babies were born(P＞0.05).(5)A mother's HbA1c level has a negative correlation with her baby's blood glucose in 1 hour after birth(r=-0.401,P＜0.05).Conclusion The higher HbA1c level of pregnant women with GDM increases,the higher risks of their neonatal hypoglycemia and threshold blood glucose are.

Objective To evaluate the image quality of dynamic three-dimensional contrast enhanced ultrasonography(3D-CEUS) in liver tumors.Methods Twenty-five patients were examed with 2D-CEUS and dynamic 3D-CEUS.Contrast-enhanced computed tomography or magnetic resonance imaging(CECT/MRI) were performed early or late.Two readers reviewed the images of both modalities and graded the images according to diagnostic criteria as follows:tumor blood fusion in arterial phase(unclear-score 0,moderate-score 1,clear-score 2),tumor boundry and relationship with periphery tissues (unclear score 0,moderate-score 1,clear-score 2).The concordance between the two modalities for showing liver tumors was evaluated by Kappa test.Results Twenty-three of 25 danymic 3D-CEUS were displayed successfully versus total objects in CECT/ MRI.Among them,for showing blood fusion,16 lesions scored 2,7 lesions scored 1,2 lesions scored 0 in danymic 3D-CEUS,meanwhile 18 lesions scored 2,7 lesions scored 1,0 lesion scored 0 in CECT/MRI,the Kappa value was 0.65.For showing tumor boundry and relationship with peripherytissues,16 lesions scored 2,7 lesions scored 1,2 lesions scored 0 in danymic 3D-CEUS,meanwhile 21 lesions scored 2,4 lesions scored 1,0 lesion scored 0 in CECT/MRI,the Kappa value was 0.52.Conclusions Danymic 3D-CEUS was shown to be useful for displaying tumor blood fusion,boundry and relationship with periphery tissues in single liver tuomor,the concordance between dynamic CEUS and CECT/MRI for single liver tuomor was fair.For huge liver tumor and multi-tumors,3D-CEUS can not give overall information.

BACKGROUND: Xinjiang is a multi-ethnic region with significant differences in local geographical position, economic development and climatic environment. OBJECTIVE: To analyze the occurrence and development tendency of birth defects, disease categories and disparity among different ethnic groups and regions in Xinjiang.METHODS: A stratified cluster random sampling observation was performed in 13 counties (cities) according to the status of ethnical distribution and local economics of Xinjiang. Quarter Report Sheet on Babies and The defect babies register card were filled as the scheme of Chinese birth defect monitoring, and ICD10 diagnostic code was adopted in birth defect diagnosis. The birth defects rate was calculated from January 2005 to December 2008, and the disease categories and disparity among different ethnic groups and regions in Xinjiang were analyzed. RESULTS AND CONCLUSION: The average incidence rate of birth defect was 9.74‰, which was dramatically descended in 2006 and ascended afterward yearly. The incidence rate of countryside was higher than city, and male more than female. In geography, south of Tianshan Mountain was higher than north and east in birth defect incidence. Among major ethnic groups in Xinjiang, Sibe and Uygur had the highest birth defect incidence rate, followed by Man, Hazakh, and Han. The birth defect incidence of Han, Uygur and Hazakh people showed descend tendency, Hui, Mongolia, and Man people fluctuated, yet Sibe's rate had a change of rise and fall. The first five birth defect entities were neural tube deformity, cleft lips, anencephaly, congenital hydrocephalus and cleft palate combined with cleft lips. The birth defects rates are different from ethnic groups and regions in Xinjiang.

Objective To explore the relationship of post-transplant major histocompatibility complex class I chain-related gene A(MICA)antibody status and renal allograft function in clinical stable phase.Methods Fifty-seven patients accepted renal allografts followed up for at least 6 months were detected with the levels and specialties of MICA antibodies by Flow PRATM beads.Simultaneously,their serum ereatinine levels were tested as well.The impact of MICA antibody status on renal allograft function was assessed.Results Among the 57 patients,38 cases showed no HLA and MICA antibody.11 cases had HLA antibodies but not MICA antibody,8 cases had MICA antibodies and 3 cases had both MICA and HLA antibodies.There were 5 patients with MICA019 antibodies.3 patients with MICA027 antibodies,2 patients with MICA018 antibodies,while 1 patient with MICA004 and MICA017 antibodies,respectively.There were 9 patients with antibody positive score higher than 6,accounting 75%(9/12).Except age,there was no significant difference between patients with positive and negative MICA antibodies in the aspects of blood transfusion history,CDC,and cold ischemia time(P＞0.05).The average ages were(32.5±7.9)years for MICA antibodypositive patients and were(43.0±1 0.4)years for MICA antibody-negative patients(P=0.008).MICA antibody-positive patients without HLA antibody had higher serum creatinine level[(117.20±12.30)μmol/L]than MICA and HLA antibody-negative patients[(89.40±28.95)μmol/L,P＜0.05].Conclusions The measurement of MICA antibodies has prognostic value in the assessment of patients without HLA antibodies after renal transplantation.MICA antibody positive has clear association with chronic renal allograft function decline.

Objective To evaluate the effect of health education on controlling endemic fluorosis in Shaanxi Province between 2004 and 2006. Methods Hanbin, Pingli, Ziyang and Hanyin were selected for the investigation in 2004;in addition to the four areas, Zhengping, Shiquan and Langao were also for the investigation in 2006. Two schools were selected in each area, and 2 villages as the investigation spots. Fifty pupils in the fifth grade in each school, and 30 housewives between 25 - 50 years old in each village were chosen as the research subjects. Referring to the health education questionnaire in Technique Scheme of Endemic Disease Prevention Granted by Central Government of 2004, the degree of health education of endemic fluorine, arsenic poisoning in pupils and housewives were investigated. Results In 2004 and 2006, the average mark of pupils in school was 54.7 and 83.6, the pass rate was 57.5% (230/400) and 90.2% (629/697), respectively;the average mark of housewives was 59.7 and 83.9, the passing rate was 59.6% (143/240), 87.6%(338/386) respectively, indicating that the outcome was improved obviously in 2006 compared to that in 2004. Conclusions In the past three years, health knowledge of endemic arsenic and fluorosis has been improved among pupils and housewives in these areas.

Objective To study the influence of human leucocyte antigen(HLA) and major his-tocompatibility complex class Ⅰ chain-related gene A (MICA) specific antibodies on renal allograft function and graft rejective reaction by monitoring their changes from preoperative to postoperative pe-riods. Methods Twenty-seven patients with renal aliografts were tested with the specificity of anti-HLA antibodies (anti-HLA class Ⅰ and anti-HLA class Ⅱ) and anti-MICA antibodies and their posi-tive value changes by flow PRATM beads. The HLA genotype was integrated to distinguish donor specific antibody(DSA) and non-donor specific antibody(NDSA). Their serum creatinine levels and clinical data were analyzed simultaneously. Results Of the 27 patients, 22 cases accepted renal transplantation from dead bodies and 5 eases accepted from live donors. Except 1 failed patient, the other 26 patients had good functional renal allografts. Twenty-four survival patients were followed up on month 1, 3, 6 and 12 after transplantation. Seven out of 27 patients had pre-exist antibody before transplantation. Among them, 2 patients had anti-HLA antibody; 3 patients had anti-MICA antibody; 2 patients had both anti-HLA and anti-MICA antibody. Three patients with no anti-HLA and anti-MICA antibodies before transplantation created antibodies after transplantation from 3 to 6 months. One patient created NDSA after transplantation and appeared chronic rejection. There were 3 patients who had anti-MICA antibodies before transplantation. The expression levels of antibodies had changed from high to low, but the specific anti-MICA antibody had not changed during the follow-up on month 1, 3, 6 and 12 after transplantation. The patient with pre-transplantation low level of anti-HLA class Ⅱ antibody appeared acute rejection with fever and his CMV was positive as well. The patient's SCr levels changed from 171 μmol/L to 236 μmol/L after I to 3 months post-transplantation. Twenty-four patients were divided into positive and negative groups according to the specific antibody. There was significant difference of SCr levels between the 2 groups 1 month and 1 year after transplantation(P= 0.03, 0.05). Conclusions It is important to detect the specificity and positive value of anti-HLA antibodies and anti-MICA antibody regularly during the post transplantation follow-up. This will make an effective therapy for decreasing the occurrenee and development of acute or chronic rejection and hy-pofunction on renal allograft.

Objective To investigate the effect of glutamine (Gln) on the content of reduced glutathione hormone (GSH) and aminoglutaminic acid (Glu) of spinal cord following ischemia-reperfusion injury. Methods Totally 40 healthy adult male rabbits were randomly divided into five groups: sham-operation group (S group), ischemia-reperfusion injury group (I/R group), low-dose glutamine group (L Gln group), median-dose glutamine group (M Gln group) and high-dose glutamine group (H Gln group). After glutamine preconditioning, the model of spinal cord ischemia-reporfasion injury was established according to Zivin's method. The general status of animals was observed and the changes of Jacobs scoring were recorded in each group. Malondialdehydes (MDA), GSH, Glu and superoxide dismutase (SOD) activity in lumbar spinal cord tissues were determined using chemical colorimetry. The neuron number and deviation rate in spinal cord anterior horn were observed histopathologically. Results There was no significant difference between L Gin group and I/R group in behavior scoring, SOD activity, content of MDA and Glu, neuron number and deviation rate of spinal cord (P>0.05); however, there was a significant difference in GSH content of spinal cord (P<0.05). M Gln group and I/R group differed significantly (P<0.05) in behavior scoring, SOD activity, content of MDA, Glu, GSH, neuron number and deviation rate of spinal cord. Between H Gln group and M Gln group, there was no significant difference in behavior scoring, content of MDA and Glu, SOD activity, neuron number and aberration rate in spinal cord (P>0.05), whereas there was a significant difference in SOD activity and Giu content (P<0.05). Conclusion Pretreatment with medium-dose glutamine has a protective effect on spinal cord ischemia-reporfasion injury in rabbits, which may be related to the maintenance of GSH content, increase of SOD activity and reduction of MDA.
