As an immune regulator, vitamin D plays a role in asthma. In the fetus, vitamin D participates in immune system and lung development. It has been reported that vitamin D deficiency may explain a portion of the asthma epidemic. Beneficial associations have been reported between vitamin D and asthma severity in children. Epidemiologic studies have also suggested that higher prenatal vitamin D intakes have a protective role against wheezing illnesses in young children. In addition, vitamin D may play a therapeutic role in steroid resistant asthmatics and there is interest in using vitamin D therapeutic-ally to complement conventional asthma therapy, such as specific immunotherapy.

Objective To investigate the relationship between gestational hypothyroidism and preeclampsia.Methods A retrospective study was conducted on 1 776 patients with gestational hypothyroidism,who gave birth in the International Peace Maternity & Child Health Hospital of China Welfare Institute,Shanghai Jiaotong University School of Medicine from January 2013 to December 2014.They were divided into three groups,including Improving Group (n=1 469),Progressing Group (n=133) and Remaining Group (n=174),based on their thyroid function at the first and third trimesters.Levels of thyroid hormones in the first and third trimesters were analyzed.Incidences of preeclampsia in those patients were calculated.And the correlation between thyroid function and incidence of preeclampsia was analyzed.T-test,Mann-Whitney U test,Chi-square test,variance analysis (SNK method) and Kruskal-Wallis H test or Logistic regression were performed for statistical analysis.Results (1) There were no statistical differences in age,gravidity and parity among the three groups.The pregestational body mass index in Progressing Group was lower than that in Improving group (21.1 ±2.9 vs 21.8±2.8,P＜0.05).(2) In the first trimester,the level of thyroid stimulating hormone (TSH) in Remaining Group was higher than those in Improving and Progressing Groups [(4.21 ± 1.69) vs (3.77±.3.03) and (2.00±0.57) mU/L,F=27.635,P＜0.01],and that in Improving Group was higher than that in Progressing Group (P＜0.05).The level of free thyroxine (FT4) in Progressing Group was higher than those in Improving and Remaining Groups [(16.18±9.67) vs (14.58± 1.71) and (14.54± 1.74) pmol/L,F=16.188,P＜0.01].In the third trimester,the TSH level in Remaining Group was higher than those in Improving and Progressing Groups [(5.07±0.86) vs (2.57±0.77) and (4.31 ±0.87) mU/L,F=28.986,P＜0.01],while the TSH level in Improving Group was higher than that in Progressing Group (P＜0.05).No statistical differences in FT4 levels (in the third trimester) and positive rates of thyroid peroxidase antibody (TPOAb) Were observed in the three groups.(3) Blood pressures (including diastolic and systolic blood pressures) in the first trimester and diastolic pressures in the third trimester showed no significant differences among the three groups.Systolic pressure of Improving Group in the third trimester was lower than that of Progressing Group [(119.4± 11.9) vs (121.8± 14.2) mmHg,P＜0.05,1 mmHg=0.133 kPa].(4) The incidence of preeclampsia in Progressing Group was higher than those in Improving and Remaining Groups [7.52％ (10/133) vs 1.29％ (19/1 469) and 3.45％ (6/174),x2=26.646,P＜0.01],and the incidence in Progressing Group was higher than those in Remaining and Improving Groups (both P＜0.05).The incidence of severe preeclampsia in Progressing Group was higher than that in Improving Group [6.02％ (8/133) vs 0.41％ (6/1 469),P＜0.05].There were no significant differences in incidences of mild preeclampsia among the three groups.(5) After adjusting for age,body mass index,gravidity and parity,the risk of severe preeclampsia in Improving Group was lower than that in Remaining Group (OR=0.233,95％CI:0.057-0.946,P＜0.05).Conclusions By improving thyroid function in pregnant women with hypothyroidism,the risk of preeclampsia,especially severe preeclampsia,could be reduced,which could improve maternal and neonatal outcomes.

Objective To investigate the effects of combination of aniso-dosage of Astragalus and Arctium on the glycolipin metabolism and renal lesion in diabetic rats.Method Streptozotocin (STZ)-induced diabetic rats were established as experimental model.The diabetic rats were randomized into model group and mixture-treated group.Astragalus and Arctium were divided into three dosages (low,moderate,high) respectively and combined according to orthogonal experimental design and were administrated to the mixture-treated group.At the 4th and 8th week,parameters of blood,urine and renal tissue were examined.The blood sugar,cholesterol,triglycerol,HbA1c were detected by analysis meter of biochemistry,urine microalbumin by radioimmunoassay (RIA) and 24 h urine protein by colorimetry.The HE and PAS staining were used to observe the change of glomerular ECM.Results At the 4th weekend,the combination of Arctium high-dosage had better effects on decreasing blood sugar and cholesterol.While at the 8th weekend,the effects of mixture were gradually augment with the Astragalus dosage increasing on decreasing triglycerol,24 h urine protein and ECM.Conclusion The compatibility of aniso-dosage of Astragalus and Arctium could rectify the metabolic disturbance of glycometabolism and lipid metabolism,and lessen the renal lesions.The compatibility had different effects on various experiment phases.

Objective To explore the relationship between parental marital quality and depressive behavior in children.Methods Using the method of stratified cluster random sampling,1 311 mothers whose children were 4 to 7 from Shenzhen' s kindergartens were randomnly selected and filled out Achenbach Child Behavior Checklist(CBCL 4/16) and Chinese Marital Quality Questionnaire.The survey results were analyzed using SPSS statistical package.Results ①In 1 311 children,the detection rate of depressive behavior was 3.28％ (43/1 311).Based on the detection rate,the difference of children depressive behavior was not statistically significant between the gender(x2=2.860,P＞0.05),but was statistically significant among different ages(x2 =17.146,P＜0.01).Increasing depressive behavior was observed with age.②The normal group of behavioral and emotional development was better than the group which had depressive behavior in marital quality(63.65±14.86) and 10 indicators of marital quality including personality magnanimous(6.03± 1.49),communication of couple(6.04± 1.48) and family roles (6.03± 1.48).There were statistical significances in marital quality(t=4.415,P＜0.05) and its 10 indicators,which was communication of couple(t=4.891,P＜ 0.05),conflict resolution (t=4.229,P＜0.05) and leisure activities(t=4.084,P＜0.05),were showed significant differences between the two groups.③The relationship between parental marital quality and depressive behavior in children were negatively correlated(r=-0.070--0.352).The better marital quality,the lower incidence of children depressive behavior,and the impact of marital quality for younger children was more significant.④In the indicators of the marital quality,communication of couples(B=-0.318,P＜0.01),and attitude towards offspring and marriage(B=-0.275,P＜0.01) could predict children depressive behavior.Conclusion It is important to improve marital quality and creat harmonious family spiritual enviromnent for reducing the incidence of children's depressive behavior.

Purpose:To investigate the clinical applicati on and curative effect of salvage treatment for primary recurrence after definitiv e radiotherapy in patients with laryngeal cancer. Methods:52 patients with laryngeal cancer receiving definitive radiotherapy in the Cancer Center of Sun Yat-sen University between 1990 and 19 95 were reviewed retrospectively. Among them, 17 patients presented with primary recurrence. Salvage treatment after radiotherapy failure included palliative ch emotherapy (5 cases) and surgical salvage (12 cases). 6 patients were salvaged b y partial laryngectomy and 6 patients by total laryngectomy. SPSS 10.0 software was used to analyze the effects, complications and the differences between diffe rent salvage treatments. Results:The overall 3- and 5-year cumulative survival rates a fter salvage treatment for primary recurrence in patients with laryngeal cancer receiving definitive radiotherapy were 56.3% and 37.5% respectively. The patient s receiving palliative chemotherapy after radiotherapy failure survived between 8 and 26 months. The 3- and 5-year cumulative survival rate in patients receiv ing surgical salvage were 75% and 50% respectively. There was significant differ ence between them analyzed by Kaplan-Meier (Log Rank=8.14, P=0.004 3). More over, the 5-year survival rates in patients salvaged by partial laryngectomy an d total laryngectomy were all 50% and there was no statistical difference betwee n them (Log Rank=0.08, P=0.7782). 5 out of 12 (41.7%) patients salvaged by s urgery presented complication after surgery, mainly infection after surgery (25 %) and pharyngocutaneous fistula (25%). Conclusions:Surgical salvage for primary recurrence in patients with laryngeal cancer receiving definitive radiotherapy could be effective.Part ial laryngectomy could be used for early primary lesion (T 1 and T 2) in patie nts with primary recurrence. The complications after salvage surgery were mainly were infection and pharyngocutaneous fistula.
