Objective To analysis newborn stage and long-term physiological and neuropsychological development in children born after assisted reproductive technology(ART),and to evaluate the safety of ART.Methods Eighty-four 6-month-old to 6-year-old children born after ART performed from January 1st,2006 to June 30th,2011 in Reproduction Center of Fuzhou General Hospital were taken as ART group; and 84 matched children born after spontaneous conception were as control group.The physiological and neuropsychological states of these children in their newborn stage and 6-month-old to 6-year-old duration were compared with Chi-square or t test.Results There was no statistical difference in childbearing age of mothers,the prevalence of gestational diabetes mellitus and hypcrtensive disorder complicating pregnancy,delivery mode,living environment,parents' education level,newborn birth length,birth weight,the rate of premature birth,low birth weight,asphyxia and hospitalized to neonatal intensive care unit between two groups (P＞0.05).In ART group,the incidence of growth retardation and abnormal social life skills was 6.0 ％ (5/84) and 1.2 ％ (1/84),and no statistical difference were found comparing with control guoup [4.8％(4/84) and 1.2％(1/84),x2 =0.12 and 0.00,P＞0.05],neither the developmental quotient (95.9±6.1 vs 94.8±5.1,t=1.25,P=0.21).Twins had higher rates of preterm birth [41.8％ (33/79) vs 10.1％(9/89),x2 =22.37,OR=6.38,95％CI:2.81-14.50,P=0.00],low birth weight [51.9％(41/79) vs 6.7％(6/89),x2=42.35,OR=14.93,95％ CI:5.84-38.16,P=0.00],asphyxia [10.1 ％ (8/79) vs 1.1 ％(1/89),x2 =6.69,OR=9.92,95％ CI:1.21～81.15,P=0.01],hospitalized to neonatal intensive care unit [36.7 ％ (29/79) vs 14.6 ％ (13/89),x2 =10.90,OR =3.39,95％CI:1.61-7.14,P=0.00] and growth retardation [11.4％(9/79) vs 0.0％(0/89),x2=10.71,RR=0.11,P=0.00] than singleton.Conclusions ART has no negative effects on children's physical and neuropsychological development.It could increase the incidence of twins,so that it might increase the incidences of preterm labor and low birth weight,which might affect the long-term physical and neuropsychological development of the offspring.

Age-related macular degeneration (AMD) is a common cause of blindness among people over 65 in developed countries.With the rapidity of population aging process,the prevalence of AMD will be further increased.The application of anti-vascular endothelial factor growth medicine in ophthalmology has made great progress in the therapeutic effect and prognosis of wet AMD.In this context,many countries and regions have successively formulated guidelines for the AMD clinical diagnosis and treatment,especially the United States,Europe and Australia.Through the analysis of AMD clinical guidelines of American Academy of Ophthalmology (AAO) in 2015,and by comparing it with AMD analysis and treatment guidelines of European Society of Retina Specialists (EURETINA) in 2014,this paper provides an accurate,effective and comprehensive diagnosis strategy and lays a foundation for providing AMD patients with quality diagnosis and treatment plans.

Objective:To analyze the learning styles of intensive care specialist nurses and to explore the application effects of the teaching method based on Kolb's learning style theory in intensive care specialist nurse training.Methods:Nurses who participated in the intensive care specialist nurse training in Chongqing during 2022 and 2023 were selected as the research subjects. Among them, the 49 nurses from 2022 were assigned to the control group, while the 50 nurses from 2023 were assigned to the experimental group. Before the training, the Kolb's Learning Style Scale was used to investigate the two groups of nurses. A new training method based on different learning styles was used in the experimental group, while the conventional training method was used in the control group. The theory, clinical practice, and satisfaction scores were compared between the two groups after training. SPSS 21.0 was used for the t-test, chi-square test, or Fisher's exact test. Results:The learning styles of the two groups were similar, with the highest proportion observed in divergent type, followed by assimilation type, and the lowest proportions in convergent type and compliant type, albeit without significant differences. The experimental group showed higher scores of theory, clinical practice, and satisfaction compared to the control group [(77.20±8.34) vs. (80.38±5.50), t=-2.24, P=0.027; (93.73±1.83) vs. (95.31±1.07), t=-5.20, P<0.001; (20.57±2.09) vs. (22.62±1.61), t=-5.46, P<0.001] Conclusion:The teaching method based on Kolb's learning style theory can improve the theory and clinical practice scores and the overall satisfaction of nurses who participate in the intensive care specialist nurse training.
