Objective To investigate the relationship between proliferative diabetic retinopathy and E-selectin level .Meth-ods Ninty-two patients with diabetic retinopathy were divided into two groups based on the results of fundus fluorescence angiography :basic diabetic retinopathy (BDR) group, and proliferative diabetic retinopathy (PDR) group.Body mass index (BMI), fasting blood-glucose (FPG), total cholesterol (TC), triglycerides (TG), hemoglobin A1c (HbA1c), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , and E-selectin levels of two groups were determined and compared .Results Compared with normal control group, the BDR and PDR group soluble E-selectin (sE-sel), FPG, HbA1c levels were increased significantly ( P <0.05).There was no significant difference in the SBP, DBP, BMI, TC, and TG levels in BDR group compared with control group ( P >0.05).The level of E-sel was positively correlated with HbA 1c and FBG in diabetic retinopathy patients .Conclusions High levels of sE-sel, HbA1c, and FPG were the important risk factors for diabetic retinopathy , and were closely related to the severity of PDR .Detection of serum sE-sel and HbA1c will help to predict the severity and prognosis of diabetic retinopathy .

Objective To evaluate the clinical effects of endobronchial ultrasound - transbronchial needle aspiration (EBUS-TBNA) in the evaluation of staging of lung cancer.Methods Between July 2008 to March 2010,the first 128 patients selected by CT or PET/CT scanning with lung cancer in whom metastatic carcinoma in the hilar and/or mediastinal lymph nodes underwent EBUS-TBNA and were clinically followed up.There were 102 males and 26 femals with the age of 37 - 85 years,average 60.1 years.Review the performance in check and the result of biopsy.Results From 128 patients of mean age 60.1 years ( range 37 - 85 ),189 lymph nodes were punctured.The mean diameter of the nodes was 12.3 mm and the range was 6-16 mm.There were no procedural complications.Accuracy,sensitivity,and specificity for EBUS-TBNA were 98.53％,98.50％,and 100％,respectively.Conclusion EBUS-TBNA allows real-time visualization of mediastinal and hilar lymph nodes,allowing sampling safely and efficiently.It has great potential for diagnosis of staging of lung cancer.

Objective:To study the clinical feasibility of transplanting human neural stem cells in treatment of cerebellar atrophy (CA).Methods:The cells from human fetal cerebellum(8-10 weeks gestation) were expanded in vitro and were allowed to differentiate into neurospheres,the latter were then implanted into CA dentate nuclei with stereotactic operation in 21 CA patients(8 male and 13 female with age ranging 19-71,mean 46) from Feb. 2000 to Aug. 2003. Results:The cells of fetal cerebellum were expanded by 10 7 folds in undifferentiated state. The effective rates were 61.9% 3 months after transplantation,85.7% 6 months after transplantation, and 90.4% during a follow-up of 12-28 months (mean 18 months).Conclusion:It is feasible and effective to implant the neural stem cells expanded in vitro for treatment of CA,but the long-term effectiveness should be futher observed.

Objective:To evaluate the morphological and functional changes of the heart during second trimester fetuses with ventricular septal defect (VSD) using fetal heart quantification (fetal HQ) technology.Methods:A prospective study was conducted from July 2022 to January 2024 at Chengdu Women′s and Children′s Central Hospital, collecting 91 singleton fetuses diagnosed with isolated VSD (VSD group) and 91 normal fetuses matched for gestational age (control group). Fetal HQ technology was used to measure the length and width of the four-chamber view of the fetal heart, obtaining the global sphericity index (GSI). Speckle tracking technology was used to track the endocardial motion trajectories of the left and right ventricles during diastole and systole, obtaining parameters such as left and right ventricular global longitudinal strain (LV-GLS and RV-GLS), end-diastolic diameter (EDD), 24-segment sphericity index (SI), 24-segment fraction of shortening (FS), left ventricular ejection fraction (LV-EF), fraction of area change (FAC), left ventricular stroke volume (LV-SV), and left ventricular cardiac output (LV-CO).The differences between groups were compared, and the correlations between the values of VSD and GSI, GLS, and FAC were evaluated.Results:The EDD of the left ventricular segments 20-23 in the VSD group was lower, while the SI value of the right ventricular segments 1-4 in the VSD group was higher than that in the control group (all P<0.05). There was no statistically significant difference in GSI between the two groups ( P>0.05). LV-GLS in the VSD group was lower than that in the control group ( P<0.05). There was no statistically significant difference in RV-GLS ( P>0.05). Values of LV-FAC, LV-EF, LV-SV, and LV-CO in the VSD group were significantly lower than those in the control group (all P<0.05). The FS value of left ventricular segments 1-10 in the VSD group presented lower, but the FS value of right ventricular segments 7-21 higher compared to controls(all P<0.05). LV-GLS and LV-FAC absolute values were negatively correlated with the size of VSD ( r=-0.309, P=0.004; r=-0.264, P=0.015), while GSI, RV-GLS, and RV-FAC showed no significant correlation with the size of VSD (all P>0.05). Conclusions:The overall sphericity index of second trimester VSD fetuses is normal, but there are changes in the shape of the left ventricular apical segments and the right ventricular basal segments, with the left heart chamber tending to be flatter and the right heart chamber more fusiform. The left ventricular systolic function of VSD fetuses is significantly reduced, the local systolic function of right ventricular increases while the global systolic function shows no significant change. The absolute values of LV-GLS and LV-FAC in VSD fetuses are negatively correlated with the size of VSD.

Objective: To analyze the detection rate of sleep problems such as sleep delay and deficiency in preschool children in the middle and lower reaches of the Yangtze River in China,and to provide the reference for the standard of sleeping mode among preschool students. Methods: From October to November 2017, a questionnaire survey was conducted among 27 200 preschool children in 11 cities in Hubei, Anhui and Jiangsu provinces in the middle and lower reaches of the Yangtze River in China. Epidemiology of sleep delays, deficiencies and sleep patterns in preschool children was described. Results: The detection rate of sleep problems in preschool children in the middle and lower reaches of the Yangtze River was 15.3%. Taking the length of sleep and bedtime as the main analysis points, it was found that the average sleeping time point of each age group was 21:31, and the detection rate of bedtime delay was 86.5%. The average length of sleep was (10.60±1.12) hours. The detection rate of sleep deprivation in preschool children was 15.7%. Sleep delay was positively correlated with girls, age increase and parents’ higher educational level (P<0.05), and negatively correlated with living in the city, non-only child and bedroom without TV (P<0.01) .The detection rate of sleep deprivation was positively correlated with children of high age group (4yearold group：OR=1.32，95%CI=1.19-1.46；5-year-old group：OR=2.10，95%CI=1.91-2.32；6-year-old group：OR=2.47，95%CI=2.20-2.77)(P<0.01), and negatively correlated with no TV in bedroom (OR=0.91，95%CI=0.84-0.98) and no light in sleep (OR=0.87，95%CI=0.78-0.97)(P<0.05). Conclusion Preschool children sleep delay and sleep deprivation and other sleep problems are more prominent, affected by family environment and other factors.

Objective:To explore the effect of parental rearing patterns and their consistency on the emotional and behavioral problems of preschool children.Methods:From October to November 2017, 27 987 children aged 3 to 6 years old from 109 kindergartens in 11 cities of Hubei, Anhui and Jiangsu Provinces were selected by using the cluster sampling method. A total of 27 200 valid questionnaires which were completed by subjects' parents were collected. The emotional and behavioral problems of preschool children were collected by "strengths and difficulties questionnaire" and the parental rearing patterns were evaluated by the "Parental Behavior Scale". The differences in emotional and behavioral abnormality rates of preschool children with different characteristics were analyzed; with emotional and behavioral problems as dependent variables and parental support/participation and compulsion/hostility as independent variables, the multivariate logistic regression model was used to analyze the effect of parental rearing patterns and their consistency on the emotional and behavioral problems of preschool children.Results:The age of children was (4.35±0.96) years old, and 51.4% of children were 13 975 males. There were 24 634 (90.6%) urban children and 17 916 (65.9%) only children. Both parents with strong support/participation accounted for 14.9%, and those with poor support/participation accounted for 11.9%; both parents with strong compulsion/hostility accounted for 15.2%, and those with low compulsion/hostility accounted for 11.3%. The rates of emotional symptoms, conduct behavior, hyperactive behavior, peer interaction, total difficulty score, and abnormal prosocial behavior of preschool children were 9.5%, 9.5%, 18.2%, 24.5%, 11.2%, and 10.2%, respectively. The multivariate logistic regression model analysis showed that after adjusting for gender, only child, living area, family economic status, mother′s age and education level, father′s education level, and other factors, compared with fathers/mothers with strong support/participation and low compulsion/hostility and parents with strong support/participation and low compulsion/hostility, preschool children who had fathers/mothers with poor support/participation and strong compulsion/hostility or parents with poor support/participation and strong compulsion/hostility were more likely to have emotional symptoms, conduct behavior, hyperactive behavior, peer interaction, total difficulty score, and abnormal prosocial behavior ( P<0.05). Conclusions:Parental rearing patterns and their consistency are related to the emotional and behavioral problems of preschool children.
