ABSTRACT
Objective To assess the growth of monochorionic diamniotic (MCDA) twins discordant for birth weight during their first 24 months of life.Methods Clinical data and growth parameters from birth to 24 months of age of 31 pairs(62 cases) of birth weight-discordant MCDA twins (≥ 25％ difference in birth weight) who were born alive in the First Affiliated Hospital,Sun Yat-sen University between January 1,2010 and June 30,2016 were retrospectively analyzed.Each pair of twins was divided into the large birth weight group (31 cases) and the small birth weight group (31 cases).All datas were statistically analyzed with Chisquare test,paired t test,analysis of variance or LSD-t test.Results (1) The incidence of birth defects and hypoproteinemia in the small birth weight group were higher than that in the large birth weight group [29.0％ (9/31) vs 0.0％ (0/31),54.8％ (17/31) vs 25.8％ (8/31);x2=8.319 and 5.429;both P ＜ 0.05].(2) The standard deviation scores (SDS) of weight,length and head circumference at birth and 1,6,12,18 and 24 months of age of the small birth weight group were lower than those of the large birth weight group [birth:(-2.00 ± 0.66) vs (-0.04±0.60),(-1.83±1.13) vs (-0.37±0.83),(-1.42±1.03) vs (0.17±0.84),t=17.214,8.390 and 7.759;1 month:(-1.77±0.81) vs (-0.60±0.65),(-2.36±1.20) vs (-0.94±0.74),(-1.71±1.26) vs (-0.44± 1.09),t=9.424,9.059 and 7.197;6 months (-1.00±0.84) vs (-0.09±0.56),(-1.31 ± 1.22) vs (-0.04±0.80),(0.30±1.51) vs (1.11 ± 1.20),t=-7.578,7.988 and 6.091;12 months:(-0.34±1.06) vs (0.47±0.79),(-1.00±0.92) vs (-0.14±0.73),(-0.16±0.76) vs (0.49±0.58),t=5.747,7.155 and 5.664;18 months:(-0.06±0.95) vs (0.74±0.66),(-0.92± 1.07) vs (-0.24±0.92),(-0.32±0.72) vs (0.29±0.66),t=6.153,4.496 and 3.877;24 months:(0.20±0.79) vs (0.88±0.62),(-0.66±0.59) vs (0.01 ±0.67),(-0.37±0.60) vs (0.34±0.68),t=5.317,4.800 and 4.905;all P ＜ 0.001].However,the changes in SDS (△ SDS) of weight,length and head circumference from birth to 24 months of age and the incidence of △ SDS ＞ 0.67 were significantly higher in the small birth weight group than those in the large birth weight group [△SDS:(2.20± 1.10) vs (0.92±0.91),(1.17± 1.21) vs (0.37± 1.14),(1.05± 1.07) vs (0.16±0.89),t=8.422,3.918 and 3.547,all P ＜ 0.001;△SDS ＞ 0.67:93.5％ (29/31) vs 61.3％ (19/31),61.3％ (19/31) vs 35.5％ (11/31),61.3％ (19/31) vs 29.0％ (9/31),x2=9.226,4.133 and 6.53 1,all P ＜ 0.05].(3) The difference in SDS for weight,length and head circumference between the large and small birth weight twins at 24 months of age were significantly lower than those at birth [(0.68 ± 0.71) vs (1.95 ± 0.63),(0.67 ± 0.77) vs (1.46± 0.97),(0.71 ± 0.80) vs (1.60±1.15);all P ＜ 0.05].Conclusions Growth differences are found between birth weight-discordant MCDA twins all the way to 24 months of age from birth at a reduced trend.
ABSTRACT
Objective To explore the clinical effect of the application of modified Chaihuguizhi dried ginger soup in the treatment of liver stagnation and spleen deficiency migraine.Methods 102 cases of liver stagnation and spleen deficiency migraine patients treated in our hospital from June 2014 to February 2016 were selected and randomly divided into two groups.The control group were given conventional western medicine; the observation group were given modified Chaihuguizhi dried ginger soup.The clinical curative effect, accompanied symptoms before and after the treatment, duration, degree of pain, the symptom scores of episode, and plasma specific viscosity, whole blood viscosity, hematocrit of red blood cell (HCT), serum 5-hydroxytryptamine(5-HT) level, medication safety during the treatment of the groups were recorded and compared.Results The total effective rate of the observation group (92.16%) was significantly higher than the control group (76.47%) (P<0.05); accompanied symptoms, duration, degree of pain and the number of attacks of the two groups after the treatment, compared with those before the treatment, improved significantly( P<0.01), and the decrease degree of the observation group was more significant(P<0.01);compared with those before the treatment, the plasma specific viscosity, blood viscosity, HCT and 5-HT levels improved significantly in the two groups after the treatment(P<0.01), and the observation group was better(P<0.01).Conclusion The application of Chaihuguizhi dried ginger soup in the treatment of migraine of liver stagnation and spleen deficiency is more conducive to ease the clinical symptoms, with more remarkable curative effect, safely and reliably, which has high clinical reference value.
ABSTRACT
Objective To assess the incidence of extrauterine growth retardation (EUGR) in very low birth weight (VLBW) preterm infants and to evaluate the effects of nutritional support and morbidities on EUGR.Methods Data of VLBW preterm infants ＜ 34 weeks of gestation admitted to the Neonatal Intensive Care Unit (NICU) of the First Affiliated Hospital of Sun Yat-Sen University between January 1,2005 and December 31,2010 were reviewed.Those VLBW preterm infants were divided into the EUGR group (n=67) and the non-EUGR group (n=40).Perinatal data,growth data,nutritional information and morbidities were compared between the two groups.The incidence of EUGR in VLBW preterm infants was assessed and the associated risk factors were analyzed.Independent samples t,Chi-square and rank sum tests and Logistic regression analysis were used for statistical analyses.Results A total of 107 VLBW infants survived to discharge.The average gestational age in the EUGR group was much lower than that in the non-EUGR group [(30.0±2.1) weeks vs (30.9 ± 1.1) weeks,t=2.904,P=0.002].However,the incidences of small for gestational age (SGA) and maternal hypertension in the EUGR group was higher than that in the non-EUGR group [SGA:53.7％ (36/67) vs 15.0％ (6/40),x2=15.575,P ＜ 0.01; maternal hypertension:40.3％ (27/67) vs 20.0％ (8/40),x2=4.689,P=0.030].Standard deviation score (SDS) of birth weight and weight at discharge in the EUGR group was lower than that in the non-EUGR group [SDS of birth weight:(--1.9±0.8) vs (--1.1±0.7),t=5.418; weight at discharge:-2.6 (-3.0--2.0) vs-0.5 (-0.9--0.1),U=30.271; both P ＜ 0.01].The velocity of weight gain in the EUGR group was lower than that in the non-EUGR group [(12.0±4.4) g/(kg · d) vs (16.1±4.0) g/(kg · d),t=1.879,P=0.036],while the maximum percentage of weight loss and the age at maximum weight loss in the EUGR group was higher than that in the non-EUGR group [percentage of weight loss:(13.2± 1.7)％ vs (9.0± 1.6)％,t=12.832,P ＜ 0.01; age:(13.4±3.5) vs (10.9±4.3) d,t=3.113,P=0.001].The time to achieve full enteral feeds,3 g/(kg · d) protein and 120 kcal/(kg · d) calories intake were longer in than the EUGR group [(39.7 ± 8.2) vs (30.8±6.1) d,t=6.293,P=0.007; (21.4±5.8) vs (17.5±1.3) d,t=4.286,P=0.002; (28.4±6.0) vs (20.3±5.4) d,t=7.198,P=0.015; 1 kcal=4.184 k J].The cumulative caloric deficit and cumulative protein deficit in the first two weeks of life in the EUGR group were significantly higher than those in the non-EUGR group [(600.9±49.3) vs (536.4 ± 55.2) kcal/kg,t=6.082,P ＜ 0.01; (17.4 ± 0.8) vs (12.4 ± 0.8) g/kg,t=31.279,P=0.003,respectively].The incidences of late-onset infection and bronchopulmonary dysplasia (BPD) in the EUGR group was significantly higher than that in the non-EUGR group [77.6％ (52/67) vs 40.0％ (16/40),x2=15.300,P ＜ 0.01;38.8％ (26/67) vs 17.5％ (7/40),x2=5.330,P=0.040,respectively].The length of oxygen therapy and mechanical ventilation in the EUGR group were significantly longer than that in the non-EUGR group [(44.5 ±4.5) vs (32.5± 1.5) d,t=20.042,P=0.030; 9.5(6.5-44.0) d vs 6.2(5.0-35.5) d,U=19.195,P=0.004,respectively].Logistic regression analysis showed that SGA,gestational age,BPD,late-onset infection,time to achieve full enteral feeds and 3 g/(kg · d) protein intake and the cumulative caloric deficit in the first two weeks after birth were the independent risk factors for EUGR (all P ＜ 0.05).Conclusions EUGR remains a serious issue in VLBW preterm infants,especially SGA,in the NICU.An early aggressive nutritional strategy,prevention of BPD and infection,and improvement of perinatal care may facilitate a reduction in the occurrence of EUGR.
