RESUMO
Objective To analyze the risk factors of adverse neurodevelopmental prognostic in very/extremely low birth weight infants (VLBWI/ELBWI).Methods The 24 hours VLBWI/ELBWI admitted to the neonatal intensive care unit between January 2016 and October 2016 were enrolled.These infants were followed up and neurodevelopmental evaluation was performed at a corrected age of 12 months by using the Bayley Scales of Infant Development Ⅱ (BSID-Ⅱ).According to the neurodevelopmental outcomes,they were divided into normal and abnormal neurodevelopment groups.The data of prenatal,intrapartum and postpartum periods in the two groups were compared.Potential risk factors of neurodevelopmental impairment were analyzed with Logistic stepwise regression.Results A total of 167 VLBWI/ELBWI were enrolled,among which 14 cases died during hospitalization or after giving up treatment.At the corrected age of 12 months,140(91.5％) infants completed follow-up and 13(8.5％) were lost to follow-up.Among 140 infants who completed neurodevelopmental evaluation at the corrected age of 12 months,there were 86 males,54 females,and in which 28 cases had extremely low birth weight,112 cases with very low birth weight,with gestational age of (30.4 ± 2.2) weeks (25.3-36.0 weeks).There were one hundred and twenty-five cases with normal neurodevelopmental outcomes and 15 cases with abnormal neurodevelopmental outcomes.The results of univariate analysis showed that birth weight ＜ 1 000 g,exposure to antenatal steroids,N-terminal brain natriuretic peptide (NT-proBNP) ≥35 000 ng/L and bronchopulmonary dysplasia (BPD) in the two groups were statistically significant (P ＜ 0.05).Logistic stepwise regression showed that NT-proBNP level ≥ 35 000 ng/L may independently predict neurodevelopmental impairment among VLBWI/ELBWI (OR =22.774,95％ CI:3.079-168.425,P =0.002).Exposure to antenatal steroids may be a protective factor for neurodevelopmental impairment (OR =0.125,95％ CI:0.020-0.782,P =0.026).Conclusions Plasma NT-proBNP level ≥ 35 000 ng/L may independently predict neurodevelopmental impairment among VLBWI/ELBWI.Antenatal corticosteroids may be the protective factor of poor neurodevelopmental outcomes.

RESUMO
Objective To investigate the normal development of anterior and posterior acetabulum in children through measuring anterior and posterior acetabular indexes with the baseline from the thinnest point of acetabulum to the center of femoral head.Methods MRI data in 165 normal children aged 0-12 years were collected.The baselines were drawn from the center of the femoral head to the thinnest point of acetabulum (method 1) and from the one midpoint of Y cartilage to the contralateral (method 2),then the anterior or posterior bony acetabular index (A/PBAI) and anterior or posterior cartilaginous acetabular indexes (A/PCAI) were measured.The consistency of above parameters measured using two methods and between two observers was observed,and the correlation with parameters-gestational ages was analyzed.Results The consistency of ABAI (ICC=0.832) measured with two methods was good,and the consistency of ACAI (ICC=0.535),PBAI (ICC=0.565) and PCAI (ICC=0.472) was fair.The consistency between two observers was good (all ICC＞0.75).ABAI,ACAI and PBAI were negatively correlated with age (r=-0.762,-0.475,-0.368,all P＜0.001),and PCAI had no correlation with age (r=-0.190,P＜0.005).Before 4 years old,ABAI gradually decreased with age and gradually stabilized after 4 years of age.ACAI and PBAI decreased slightly with aging.PCAI did not change obviously with aging.Conclusion The measuring method of anterior and posterior acetabular indexes with the baseline from the thinnest point of acetabulum to the center of femoral head can accurately evaluate the normal development of anterior and posterior acetabulum in children.
RESUMO
Objective To evaluate the imaging characteristics of atypical teratoid/rhab doid tumor (AT/RT) of central nervous system(CNS), and to improve the diagnostic ability of the disease. Methods The clinical and imaging findings of 9 patients were retrospectively analyzed. There were 5 male and 4 female, ages 7 months to 5 years,median age was 1.4 years. MR enhancement studies were obtained in all the cases. One case had CT enhancement examination. Results The lesions were seen in brain in 8 cases and in lumbosacral spinal cord in one case. The tumors size varied from 4.8—7.8 cm, Necrosis was seen in nine cases, cystic change in eight cases and hemorrhage in five cases. The tumors had high signal on DWI, and low signal on ADC map. Dura matter invasion(2 cases), cerebrospinal fluid spread(2 cases)and intracerebral metastasis were seen. Conclusion There are some relatively specific imaging findings of primary CNS AT/RT that could assist their diagnosis.
RESUMO
Objective To investigate application effect of strengthened night nursing to the prevent of vascular crisis in patients after finger replantation. Methods A total of 155 patients with finger replantation in Hand surgery from February 2014 to February 2016 were selected as research object, 90 cases from March 2015 to February 2016 with strengthened night nursing were as the observation group,65 cases from February 2014 to February 2015 with routine nursing were as the control group. The two groups were compared of limb replantation success rate, vascular crisis rate and nursing satisfaction. Results The replantation success rate in the observation group was 90.00%(81/90)higher than 76.92%(50/65)in the control group,the occurrence of vascular crisis rate was 11.11%(10/90)lower than 27.69%(18/65)in the control group,the success rate was 7/10 higher than 10/18 in the control group, and the difference was statistically significant (χ2=4.932, 7.013, 4.216, all P<0.05). The nursing satisfaction in the observation group was (94.32 ± 3.57) points, 93.33%(84/90) higher than (91.22 ± 4.48) points, 83.08%(54/65) in the control group, and the difference was statistically significant (t=4.789, χ2=4.071, P<0.05). Conclusions Strengthened night nursing can effectively prevent vascular crisis in patients after finger replantation,improve nursing satisfaction of patients.
