OBJECTIVE: To investigate the incidence of severe neonatal hyperbilirubinemia and the management on the treatment and follow-up of this disease in Jiangsu Province, China. METHODS: The neonates with severe hyperbilirubinemia who were admitted to 13 hospitals in Jiangsu Province from January to December, 2018, were enrolled as subjects. A retrospective analysis was performed on their mediacal data and follow-up data. RESULTS: In 2018, 740 neonates with severe hyperbilirubinemia were reported from the 13 hospitals in Jiangsu Province, accounting for 2.70% (740/27 386) of the total number of neonates admitted to the department of neonatology. Among these neonates, 620 (83.8%) had severe hyperbilirubinemia, 106 (14.3%) had extremely severe hyperbilirubinemia, and 14 (1.9%) had hazardous hyperbilirubinemia. Four neonates (0.5%) were diagnosed with acute bilirubin encephalopathy. A total of 484 neonates (65.4%) were readmitted due to severe hyperbilirubinemia after discharge from the delivery institution, with a median age of 7 days, among whom 214 (44.2%) were followed up for jaundice at the outpatient service before readmission, with a median age of 6 days at the first time of outpatient examination. During hospitalization, 211 neonates (28.5%) underwent cranial MRI examinations, among whom 85 (40.3%) had high T1WI signal in the bilateral basal ganglia and the globus pallidus; 238 neonates (32.2%) underwent brainstem auditory evoked potential examinations, among whom 14 (5.9%) passed only at one side and 7 (2.9%) failed at both sides. The 17 neonates with acute bilirubin encephalopathy or hazardous hyperbilirubinemia were followed up. Except one neonate was lost to follow-up, and there were no abnormal neurological symptoms in the other neonates. CONCLUSIONS: Neonates with severe hyperbilirubinemia account for a relatively high proportion of the total number of neonates in the department of neonatology. Jaundice monitoring and management after discharge from delivery institutions need to be strengthened. For neonates with severe hyperbilirubinemia, relevant examinations should be carried out more comprehensively during hospitalization and these neonates should be followed up comprehensively and systematically after discharge.

The coastal waters adjacent to the Changjiang River estuary (CRE) are characterized by nutrient pollution and recurrent harmful algal blooms. In this study, resting cysts of Alexandrium pacificum Litaker and A. catenella (Whedon & Kof.) Balech, two major species within the A. tamarense species complex in Chinese coastal waters, were studied using sediment samples collected from the area adjacent to the CRE in May 2014 and December 2015. Cysts were detected with two real-time quantitative PCR assays, as well as the primuline-staining method. Only cysts of A. pacificum were found in the study area, which mainly distributed in the mud depositional zone near the CRE. A low-abundance region of the cysts present in spring is in accordance with the intrusive pathway of the Nearshore Kuroshio Branch Current (NKBC), suggesting that A. pacificum blooms could be regulated by seasonal intrusion of NKBC.

OBJECTIVE: To study the effect of extensively hydrolyzed formula on the growth and development in very low birth weight (VLBW) and extremely low birth weight (ELBW) infants. METHODS: A total of 375 VLBW or ELBW infants were enrolled and divided into an observation group (187 infants) and a control group (188 infants) using a random number table. The infants in the observation group were given extensively hydrolyzed formula, and when the amount of extensively hydrolyzed formula reached 10 mL/time, it was changed to the standard formula for preterm infants. The infants in the control group were given standard formula for preterm infants. Both groups were fed for 4 consecutive weeks and were compared in terms of incidence rate of feeding intolerance, time to establish full enteral feeding, time to complete meconium excretion, number of spontaneous bowel movements, growth and development, motilin level at 4 and 10 days after feeding, and incidence rate of infection. RESULTS: Compared with the control group, the observation group had a lower rate of feeding intolerance (P<0.05), a shorter duration to full enteral feeding and time to complete meconium excretion (P<0.05), a higher mean number of daily spontaneous bowel movements (P<0.05), higher body weight (1 793±317 g vs 1 621±138 g; P<0.05), head circumference (30.5±1.1 cm vs 30.0±1.6 cm; P<0.05), and body length (43.9±1.2 cm vs 42.1±2.0 cm; P<0.05), a higher motilin level at 4 and 10 days after feeding (P<0.05), and a significantly lower infection rate (P<0.05). CONCLUSIONS: Extensively hydrolyzed formula can increase motilin level, improve gastrointestinal feeding tolerance, promote early growth and development, and reduce the incidence of infection in VLBW and ELBW infants.

OBJECTIVE: To explore the relationship between histological chorioamnionitis (HCA) and fetal inflammatory response syndrome (FIRS) and brain injury in preterm infants. METHODS: One hundred and three singleton infants with premature rupture of membranes (PROM) (gestation ages of less than 34 weeks) were enrolled. All the placentas were submitted for pathological evaluation. Umbilical cord blood interleukin 6 (IL-6), interleukin 8 (IL-8), tumor necrosis factor alpha (TNF-α) and granulocyte-colony stimulating factor (G-CSF) levels were measured with liquid chip. All preterm infants accepted brain imaging examinations. Based on the placental pathological examination and umbilical cord blood level of IL-6, the 103 infants were classified into HCA⁻ FIRS⁻, HCA⁺ FIRS⁻, and HCA⁺ FIRS⁺ groups. RESULTS: The incidences of HCA, FIRS, and brain injury were 53.4%, 20.4% and 38.8% respectively. The prevalence of brain injury in HCA⁻ FIRS⁻, HCA⁺ FIRS⁻, and HCA⁺ FIRS⁺ cases was 21%, 41%, and 76% respectively (P<0.01). The grade 2 and grade 3 of placental inflammation and the inflammation at stage 2 and stage 3 increased the risk of brain injury. The cord blood levels of IL-8, TNF-α, and G-CSF in the HCA⁺ FIRS⁺ group were significantly higher than in the other two groups, and the levels of the above parameters in the HCA⁺ FIRS⁻ were higher than in the HCA⁻ FIRS⁻ group (P<0.05). CONCLUSIONS: Placental inflammation and FIRS are associated with brain injury in preterm infants. Preterm infants exposed to severe placental inflammation have an increased risk of brain injury. Cord blood IL-8, TNF-α and G-CSF may be involved in the process of brain injury in preterm infants with placental inflammation and FIRS.

OBJECTIVE: To evaluate the effect of hypothermia therapy on serum glial fibrillary acidic protein (GFAP) and ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) levels in neonates with hypoxic-ischemic encephalopathy (HIE). METHODS: Sixty-four HIE neonates were enrolled in this study. Thirty-three neonates with mild HIE were given conventional treatment and 31 neonates with moderate or severe HIE received conventional treatment and hypothermia therapy. Serum levels of GFAP and UCH-L1 were measured using ELISA before treatment and 6-12 hours after treatment. RESULTS: Serum levels of IL-6, IL-8, GFAP and UCH-L1 in the moderate/severe HIE group were significantly higher than in the mild HIE group (P<0.05) before treatment. Serum GFAP level was positively correlated with serum IL-6 (r=0.54; P<0.05) and IL-8 levels (r=0.63; P<0.05), while negatively correlated with Apgar score (r=-0.47, P<0.05). After treatment, serum levels of IL-6, IL-8 and UCH-L1 in the moderate/severe HIE group were significantly reduced (P<0.05), while serum GFAP levels increased significantly (P<0.05). The patients with abnormal neurological development showed higher serum GFAP levels than those with favourable prognosis (P<0.05). Receiver operating characteristic (ROC) curves analysis demonstrated that the area under curve (AUC) of GFAP and UCH-L1 were 0.714 and 0.703 respectively. At a cut-off value of 0.07 ng/mL, the sensitivity and specificity of GFAP for the diagnosis of HIE were 77% and 78% respectively. CONCLUSIONS: Hypothermia therapy can decrease serum UCH-L1 levels and increase serum GFAP levels in neonates with HIE. Based on their diagnostic value of brain injury, GFAP and UCH-L1 are promising to be novel biomarkers for HIE.

BACKGROUND AND AIMS: Changes in key traits occurring during the processes of plant domestication have long been subjects of debate. Only in the case of genetic analysis or with extensive plant remains can specific sets of changes be documented. Historical details of the plant domestication processes are rare and other evidence of morphological change can be difficult to obtain, especially for those vegetables that lack a substantial body of archaeological data. Botanical records chronicled in the ancient literature of established ancient civilizations, such as that of China, are invaluable resources for the study and understanding of the process of plant domestication. Here, the considerable body of ancient Chinese literature is used to explore the domestication process that has occurred with the eggplant (Solanum melongena), an important vegetable in Old World. METHODS: Information about eggplant domestication in the ancient Chinese literature was retrieved using a variety of methods. The information obtained was then sorted by taxon, examined and taxonomic identifications verified. KEY RESULTS: It was found that the earliest record of the eggplant documented in ancient Chinese literature was in a work from 59 bc. As far as is known, this is the earliest reliable and accurately dated record of eggplant in cultivation. The analysis reveals that the process of domestication of the eggplant in China involved three principal aspects of fruit quality: size, shape and taste. These traits were actively and gradually selected; fruit size changed from small to large, taste changed from not palatable to what was termed at the time sweetish, and that over time, a wider variety of fruit shapes was cultivated. CONCLUSIONS: The results indicate that, in addition to data gleaned from archaeology and genetics, evidence as to changes in key traits occurring during the process of plant domestication and selective forces responsible for these changes can be traced through the ancient literature in some civilizations.
