Objective To explore the clinical features and risk factors of poor prognosis in neonatal necrotizing enterocolitis(NEC).Methods A retrospective study was carried out in the infants with NEC admitted to 6 cooperative hospitals in Guangdong Province between January 2005 and December 2014.The clinical features and risk factors of poor prognosis in preterm and full-term infants diagnosed NEC,early onset and late onset NEC were analyzed.Results A total of 449 cases who met the criteria were admitted during the study time.The mortality was 23.6% (106/449 cases),of which the preterm group was 24.6% (58/238 cases) while the full-term group was 22.7% (48/211 cases),the early onset group was 22.1% (45/204 cases) while the late onset group was 24.3% (57/235 cases).The median number of NEC onset in preterm group was 11 d after birth while the number of the full-term group was 6 d.Full-term infants who diagnosed NEC were more likely to manifest themselves as abdominal distension (52.1% vs.42.0%,x2 =4.597,P =0.032),vomiting(36.5% vs.17.2%,x2 =21.428,P =0.000) and bloody stool(30.3% vs.21.4%,x2 =4.653,P =0.031);but in the onset of NEC,preterm infants more likely to have feeding intolerance (21.0% vs.12.8%,x2=5.309,P =0.021).The early onset group of full-term NEC was much common in twins or multiplets(9.4% vs.1.1%,x2 =6.226,P =0.013),which rate of surgical therapy was much higher (41.0% vs.27.0%,P =0.036) and the breast-feeding rate before NEC was lower than the late onset group(14.5% vs.32.6%,x2 =9.500,P =0.002),the differences were statistically significant.The gestational age and birth weight were bigger in the early onset group of preterm NEC[(33.8 ±2.5) weeks vs.(32.2 ±2.8) weeks,t =4.261,P =0.000;(2.1 ±0.5) kg vs.(1.7 ± 0.5) kg,t =4.735,P =0.000)],but length of stay was shorter than the late onset group (18.0 d vs.26.5 d,P =0.000).Logistic regression analysis showed that the risk factors of poor prognosis of full-term NEC were shock,peritonitis and sepsis;while risk factors of poor prognosis of preterm NEC were small for gestational age infant,pulmonary hemorrhage,shock,intestinal perforation and sepsis;the risk factors of poor prognosis of the early onset group of full-term NEC was shock;while those of the late onset group were shock and peritonitis;the risk factors of poor prognosis in the early onset group of preterm NEC were shock and sepsis,while those in the late onset group were pulmonary hemorrhage,shock,intestinal perforation and sepsis.Conclusions Compared to the preterm NEC,the onset time of full-term NEC was earlier and the clinical manifestations were more typical.Early identification and management of shock,peritonitis,intestinal perforation,sepsis and pulmonary hemorrhage can reduce the risk of poor prognosis of neonate NEC.

ObjectiveTo explore the anti-abortional effect of Pangshi Antai Zhixue decoction and its mechanism in helper T lymphocyte 1 (Th1)/Th2 balance in the decidual tissues of spontaneous abortion rats with heat syndrome, based on the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. MethodAconiti Lateralis Radix Praeparata, Zingiberis Rhizoma, and Cinnamomi Cortex decoction was used to replicate the rat model of spontaneous abortion with heat syndrome. The spontaneous abortion rats with heat syndrome were randomly divided into model group, aspirin group (5.25 mg·kg-1), dydrogesterone group (3.02 mg·kg-1), Pangshi Antai Zhixue decoction high-dose (44 g·kg-1), medium-dose (22 g·kg-1), and low-dose (11 g·kg-1) groups, with ten rats in each group. Ten normal rats were divided into a normal group. Rats in each group were given corresponding drugs, Once a day for 12 d. After 24 h of the last administration, blood was collected from the abdominal aorta. The enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of β-human chorionic gonadotropin (β-HCG), progesterone (P), estradiol (E2), γ interferon (IFN-γ), and interleukin-4 (IL-4) in rat serum. The uterus and meconium tissues of rats were collected to determine the number and rate of miscarriages. Western blot was used to detect GATA3, T-bet, p38 MAPK, and its phosphorylation in the decidual tissue. ResultAs compared with the normal group, the number of live births, the β-HCG, P, E2, and IL-4 in the serum, and the GATA3 protein expression in the decidual tissue in the model group were reduced (P<0.01), whereas the number and rate of miscarriages, IFN-γ in the serum, and the expression of p-p38 MAPK and T-bet protein levels in the demolded tissues increased (P<0.01). As compared with the model group, the number of live births, the β-HCG, P, E2, and IL-4 in the serum, and the GATA3 protein expression in the decidual tissue in the Pangshi Antai Zhixue decoction medium-dose group increased (P<0.01), whereas the number and rate of miscarriages, IFN-γ in the serum, and the expression of p-p38 and T-bet protein levels in the demolded tissues reduced (P<0.01). As compared with the aspirin group, the P, E2, and IL-4 in the serum of rats in the dydrogesterone group and the Pangshi Antai Zhixue decoction high-dose and medium-dose groups increased (P<0.01), the number of live births in the Pangshi Antai Zhixue decoction medium-dose group increased (P<0.01), and the β-HCG and IFN-γ in the serum of rats in the dydrogesterone group decreased (P<0.01). The number and rate of miscarriages, IFN-γ in the serum, and T-bet and GATA3 levels in the decidual tissues of rats in the Pangshi Antai Zhixue decoction medium-dose group decreased (P<0.05). Compared with the Pangshi Antai Zhixue decoction medium-dose group, the low-dose group, high-dose group, and dydrogesterone group showed increased number and rate of miscarriages (P<0.05), and the high-dose group and dydrogesterone group decreased the number of live birth (P<0.01). The IFN-γ in the serum and p-p38 MAPK and T-bet protein in the decidual tissue in the low-dose group, and the p-p38 MAPK and T-bet protein in the decidual tissue in the high-dose group all increased (P<0.05). The β-HCG, P, and E2 in the serum of rats in the Pangshi Antai Zhixue decoction low-dose group, dydrogesterone group, and aspirin group decreased (P<0.01), and the IL-4 in the serum and GATA3 in the decidual tissue of rats in the Pangshi Antai Zhixue decoction low-dose and high-dose group and the dydrogesterone group decreased (P<0.01). ConclusionPangshi Antai Zhixue decoction realizes the effect of fetal protection by regulating the activation of p38 MAPK signal pathways and Th1/Th2 balance.
