1128 esophageal carcinoma patients were treated by radiation therapy from Jaunary 1978 to December 1981. 64 cases with new focuses in superior and inferior margin of radiative field were 2.9% and 1.6% and in another region was 1.2%. 54 cases were retreated by radiation therapy. The 1-,2-,3- and 5 years survival rates were 53.7%,24.1%,13.5% and 5.8%. We think that new focus outside radiative fields was great different from local recurrence and uncontral cancers. Those patients can still be treated by radical radiation therapy. It is reasonable to prolong 3cm in length above and below the lesion for initial radiotherapy.

Objective: To explore the mediating effect of maternal emotional symptoms on maternal adverse experiences and children s emotional behavior problems, so as to provide a scientific basis for family intervention of children with emotional behavior problems. Methods: A multi stage sampling method was used to select 12 kindergartens in 3 districts and counties of Wuhu City. The questionnaire star method was used to investigate the love of homosexuality in families and children, children s emotional behavior development questionnaire, mother s life experience questionnaire, mother s emotional symptoms questionnaire, etc. SPSS 23.0 software was used for general descriptive analysis and Spearman correlation analysis. GLS method was used to evaluate the mediating effect of maternal mental health level between maternal adverse experiences and childrens emotional and behavioral problems. Results: The difficulty factor score in the Strength and Difficulty Questionnaire (SDQ) of preschool children in Wuhu City was (10.08±4.05) points, the abnormal detection rate of the total difficulty score was 6.6%, and the abnormal detection rate of prosocial behavior was 16.5%, the total score of mother s adverse experience was positively correlated with the total score of mother s SDQ difficulties and the scores of mother s depression, anxiety and stress symptoms. The total score of children s SDQ difficulties was positively correlated with the scores of mother s depression, anxiety and stress emotions( r=0.17-0.71, P < 0.01). The results of mediating effect analysis showed that the intermediate effect coefficients of maternal depression, anxiety, stress and other emotions between the total score of maternal adverse experience and the total score of children s SDQ difficulties were statistically significant( P <0.05), and the mediating effect accounted for 22.6%, 15.2% and 17.1% of the total effect, respectively. Conclusion The relationship between maternal adverse childhood experiences and children s emotional behavior problems was influenced by maternal emotional symptoms. Attention to mothers early life experience and mental health is beneficial to the prevention and control of children s emotional and behavioral problems.

Objective : To investigate the effects of gestational diabetes mellitus (GDM) on birth outcome and umbilical artery (UA) blood flow parameters in the third trimester, and to analyze the role of UA blood flow parameters in GDM and birth outcome. Methods : Based on the birth cohort from Wuhu , Anhui , China , 189 pregnant women with GDM were collected as the case group. The non⁃GDM pregnant women were matched 1 ∶ 1 according to age and pre⁃pregnancy body mass index , and 189 normal pregnant women were selected as the control group. Pregnant women with GDM were divided into poorly controlled group and well controlled group according to fasting blood glucose in the third trimester. The UA blood flow parameters and fetal birth outcomes in the third trimester were tracked. Results : Compared with the control group , UA parameters in poorly controlled and well controlled groups significantly increased (F = 6. 63 , P < 0. 05 ; F = 4. 43 , P < 0. 05 ; F = 5. 57 , P < 0. 05) . Poor glycemic control of GDM was associated with increased birth weight and risk of larger than gestational age. The multi⁃factor linear regression model showed that the Z score of the peak systolic velocity/end diastolic velocity (S/D) in the poorly controlled group was negatively correlated with birth weight (β = - 209. 78 , 95% CI: - 301. 48 - 118. 07) . S/D index Z score mediated the relationship between poor blood glucose control and birth weight. The intermediate effect value was - 58. 41 (95% CI: - 106. 40 ~ - 19. 65) , accounting for 25. 98% of the total effect. Conclusion Poor glycemic control in GDM is a risk factor for fetal weight gain , and UA function plays a partial mediating role in influencing neonatal birth weight. GDM pregnant women should strictly control blood glucose level to better protect maternal and infant health.

Objective : To investigate the correlation between nocturnal sleep duration combined with snoring in the first trimester of pregnancyand small for gestational age(SGA) ，large for gestational age(LGA) ． Methods : Multi- variate Logistic regression model was used to analyze the association between nocturnal sleep duration ，snoring， their combined effects and SGA，LGA. Results : Compared to nocturnal sleep duration 7 to 9 h in the first trimester of pregnancy，sleep duration＜7 h was positively correlated with SGA in male newborn( OR = 4. 22，95% CI : 1. 69 - 10. 52) ; After stratified by snoring，the sleep duration of snoring women＜7 h was positively correlated with SGA ( OR = 5. 68，95% CI : 1. 02－31. 51) ，and the sleep duration of non-snoring women＜7 h was positively correlated with LGA ( OR = 2. 10，95% CI : 1. 16 －3. 81) ． Conclusion Sleep duration＜7 h in the first trimester of preg- nancy is a risk factor for SGA and LGA，and snoring may enhance the association between sleep duration＜7 h in the first trimester of pregnancy and SGA．Pregnant women should keep adequate nocturnal sleep duration to reduce the risk of abnormal neonatal weight.
