Due to the dysontogenesis of the arterial duct wall and the abnormal secretion of prostaglandin,symptomatic patent ductus arteriosus is thus often presented in preterm infants.In the past,Indomethacin or Ibuprofen (cyclooxygenase inhibitor) was always chosen to be the interventional medication.While in recent years,Acetaminophen (prostaglandin synthetase inhibitor) has become another therapeutic option for symptomatic patent ductus arteriosus with similar efficacy but less adverse events.The latest research of the mechanism,the therapeutic strategy of time,mode,dosage and duration,the efficacy and the adverse events of Acetaminophen were reviewed.

Objective To study the effectiveness of family-integrated-care (FICare) for preterm infants with moderate to severe bronchopuhnonary dysplasia (BPD) in neonatal intensive care unit (NICU).Method Preterm infants with moderate to severe BPD in Hunan Children's Hospital from January 2015 to March 2016 were selected as the objects.These infants were assigned into two groups (FICare group and control group) in the base of whether the parents agreed to implement FICare.If the infant was enrolled into FICare group,the parents need to spend 3 hours in ward every day,and participate in nursing services under the guidance of nurses.The nursing services included bathing,cuddling,skin care,breast-feeding,and so on.If the infant was enrolled into control group,these nursing services were implemented by nurses.Oxygen exposure time,breast-feeding rate,time of begin oral feeding,time of total oral feeding,weight growth rate during hospitalization,weight of discharge,length of stay,readmission rate within 30 days,the rate of parents that mastered basic care knowledge and skills when discharge from hospital,the rate of satisfaction,and the rate of follow-up within 30 days of the two groups were compared.Result There were 106 cases in our study,54 in the FICare group and 52 in the control group.Compare the FICare group and the control group,there were statistical differences between two groups in the follow aspects (all P ＜ 0.05):oxygen exposure time [(57.1 ±20.9) d vs.(71.4 ±32.6) d],breast-feeding rate (77.8％ vs.44.2％),time of total oral feeding [(46.1 4 19.6) d vs.(59.4 ± 30.2) d,length of stay [(65.8 ± 18.4) d vs.(84.3 ±35.0) d],the rate of parents that mastered basic care knowledge and skills when discharge from hospital (96.3％ vs.82.7％),the rate of satisfaction (94.4％ vs.84.6％),the rate of follow-up within 30 days (92.6％ vs.73.1％).Conclusion FICare could significantly reduce oxygen exposure time of preterm infants with moderate to severe BPD,could improve the level of parents mastered basic care knowledge and skills of preterm infants,especially in critically ill preterm children,and could shorten length of stay of them.FICare is beneficial to the healthy growth of premature infants with BPD.

Objective To investigate the changes of cardiac function at pre -and post -treatment in preterm infants with patent ductus arteriosus (PDA)in order to guide drug treatment.Methods Totally 84 preterm infants with PDA admitted to Neonatal Intensive Care Unit of Xuzhou Hospital Affiliated to Medical College of Southeast University from July 201 2 to June 201 4 were divided into 4 groups according to treatment drug:Ibuprofen group (27 cases),Indo-methacin group (24 cases),control group (1 1 cases),and Paracetamol group (22 cases).Patients were also divided into symptomatic PDA group (38 cases)and asymptomatic PDA group (46 cases)according to severity;PDA closed group (69 cases)and PDA unclosed group (1 5 cases)according to sequel.The level of plasma brain natriuretic pep-tide (BNP),cardiac troponin I (cTnI),correct QT intervals dispersion (QTcd)were monitored pre -and post -treat-ment.Data were analyzed by using SPSS 1 9.0 software.Results Three cardiac markers at post -treatment were of no significant difference among 4 treatment drugs.The changes of the cTnI and QTcd at pre -and post -treatment were of no significance.The level of BNP in symptomatic PDA group was significantly higher than that in asymptomatic PDA group at pre -treatment [(378 ±94)ng/L vs (1 47 ±75)ng/L,t =2.584,P =0.01 4].In the symptomatic PDA group,the level of BNP at post -treatment [(1 82 ±81 )ng/L]was significantly decreased than that at per -treatment (t =2.741 ,P =0.009).In the asymptomatic PDA group,there was no significant difference between the pre - and post -treatment [(1 21 ±61 )ng/L]in the level of BNP (t =1 .254,P =0.207).There was no significant difference in the level of BNP at per -treatment between PDA closed group and PDA unclosed group [(274 ±91 )ng/L vs (289 ± 87)ng/L,t =-0.874,P =0.391 ].In PDA closed group,the level of BNP at post -treatment [(1 21 ±74)ng/L] was significantly decreased compared with that at per -treatment (t =3.580,P =0.000).In PDA unclosed group, there was no significant difference between the pre - and post -treatment [(245 ±74)ng/L]in the level of BNP (t =0.854,P =0.392).Conclusion Early medication intervention for symptomatic PDA of preterm infants is benefi-cial for the closure of PDA and for attenuating negative effects on cardiac function of PDA.

OBJECTIVETo explore the change pattern of hypothalamic-pituitary-adrenal (HPA) axis and related neurotransmitters under simulated weightlessness.

METHODSA total of 40 clean-grade male Wistar rats were randomly divided into a normal group, a tail-suspension group, an electroacupuncture (EA) at Neiguan (PC 6) group, an EA at Sanyinjiao (SP 6) group, 10 rats in each group. Rats in the tail-suspension group, EA at "Neiguan" (PC 6) group and EA at "Sanyinjiao" (SP 6) group were treated with tail suspension to simulate weightlessness effect. Rats in the normal group were treated with normal diet. Rats in the tail-suspension group were treated with tail suspension for 28 d. During the time of tail suspension, rats in the EA at "Neiguan" (PC 6) group were treated with EA at "Neiguan" (PC 6), 30 min per treatment, once every two days for 14 treatments, while rats in the EA at "Sanyinjiao" (SP 6) group were treated with EA at "Sanyinjiao" (SP 6), 30 min per treatment, once every two days for 14 treatments. Samples were all collected after 4 weeks. The contents of corticotropin releasing hormone (CRH) , adrenocorticotropic hormone (ACTH), corticosterone (CORT) in as well as 5-hydroxy tryptamine (5-HT), dopamine (DA), norepinephrine (NE) were measured by using radioimmunoassay.

RESULTSCompared with the normal group, in the tail-suspension group the content of ACTH in pituitary was significantly decreased (P< 0.05), and the content of 5-HT in hypothalamus was significantly decreased (P < 0.01); the content of CRH and 5-HT in hypothalamus was significantly decreased (P < 0.01, P < 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH and 5-HT in hypothalamus was significantly decreased (P < 0.01), and the content of CORT in serum was significantly decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the tail-suspension group, the content of ACTH in hypothalamus was significantly decreased (P< 0.05) in the EA at "Neiguan" (PC 6) group; the content of CRH, ACTH and CORT was significantly decreased (P < 0.01, P < 0.05) in the EA at "Sanyinjiao" (SP 6) group. Compared with the EA at "Neiguan" (PC 6) group, the content of CORT was decreased (P < 0.05) in the EA at "Sanyinjiao" (SP 6) group.

CONCLUSIONEA can regulate the content of 5-HT in hypothalamus in tail-suspension rats, inhibit the hyperactivity of the HPA axis, in which EA at "Sanyinjiao" (SP 6) had more significant effects than "Neiguan" (PC 6), but no obvious effects on NE and DA were observed.

To elucidate the expression of WT1 in all types of leukemias and its implications for monitoring minimal residual disease in patients with acute leukemia, the peripheral blood from 55 leukemia patients and 10 normal voluteer was detected by using FQ-RT-PCR. Follow-up monitoring of WT1 expression of peripheral blood was performed for 20 patients with acute leukemia. The results showed that the expression of WT1 gene in all types of leukemias was significantly higher than that in normal control (P < 0.001). For ANLL and ALL patients, the survival time in the group of WT1 6.8 x 10(-3), (P = 0.027). Follow-up detection of the expression of WT1 in peripheral blood samples from 20 acute leukemia patients, 7 cases relapsed after complete remission has been done. In 5 of 7 relapsed patients, the expression of WT1 had obviously increased about 2 - 3 months before clinical relapse became apparent. It is concluded that the established FQ-RT-PCR method is accurate and specific. The expression of WT1 gene is relatively high in all types of leukemias compared with normal peripheral blood cells, the higher WT1 expression may associate with poor prognosis in acute leukemia, and the dynamics of WT1 level correlate with the disease status. The quantitative assessment of WT1 expression in peripheral blood samples by FQ-RT-PCR may be a useful tool for monitoring minimal residual disease.

OBJECTIVETo quantitatively assess the association between transfusions and the risk of necrotizing enterocolitis (NEC) in neonates.

METHODBoth Chinese and English literature published from Jan. 1985 to Nov. 2011 about the case-control study of the association between transfusions and neonatal NEC were retrieved by searching the electronic resource databases. A meta-analysis was then performed on the comparison and synthesis of findings from included studies. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using RevMan 5.0 software. Sensitivity analysis was conducted and possible publication bias was tested as well.

RESULTA total of 7 case-control studies (480 blood transfusion cases, 2845 control cases) were included. The meta-analysis with a random-effects model found a pooled OR of 3.35 (95% CI: 1.54-7.27). Sensitivity analysis showed that OR for post-transfusion NEC within 48 h was 4.21 (95% CI: 2.17-8.16). The OR was 4.29 (95% CI: 1.39-13.24) after factors such as gestational age and birth weight were de-confounded. The fail-safe number was 263.

CONCLUSIONBlood transfusion can increase the risk of NEC in neonates. The clinical application of this conclusion should be cautious due to limited reports. High-quality randomized control trials are still needed for the further proof of the association between blood transfusion and neonatal NEC.

OBJECTIVETo explore the clinical characteristics of Cornelia de Lange Syndrome (CdLS) and to review the latest clinical research reports.

METHODClinical and laboratory data of one case of neonatal CdLS are reported, and literature on 17 cases of CdLS in China and the international reports of the clinical and molecular biological research on this disease were reviewed.

RESULT(1) The patient was an infant with intrauterine growth retardation and born as a term small for gestational age infant with specific facial features, bone abnormality of extremities, and patent ductus arteriosus (PDA). She also had severe feeding difficulty and slow weight gain. She was followed up till 4 months of age and showed severe developmental retardation. (2) The total number of past reported case of CdLS in China was 17 with a male to female ratio of 6:12. The average age of diagnosis was 17 months. The following specific facial features could be observed: synophrys, long and curved eyelashes, hirsutism, microcephalus, low hairline, broad depressed nasal bridge, long prominent philtrum, and high palate. Most of the patients were complicated with mental retardation, recurrent vomiting or feeding difficulty, abnormal muscle tone, cutis marmorata, hypophalangism, and genitalia anomaly. Clinical manifestations of Chinese patients were similar to those of the overseas reports. The karyotype of 15 cases was investigated and was normal. The etiology of CdLS is unknown. There is no specific treatment. The commonest causes of death are lung diseases caused by gastroesophageal reflex/aspirate related pneumonia.

CONCLUSIONTypical clinical manifestations of CdLS are specific facial features (mainly synophrys, long and curved eyelashes, long prominent philtrum), complications of multi-system malformations (mainly growth and developmental retardation, esophagogastric reflex, hypophalangism), related gene mutations occurred in NIPBL, SMC1A, and SMC3 gene.

BACKGROUNDHepatocyte transplantation has been proposed as an alternative to whole-organ transplantation to support many forms of hepatic insufficiency. Unfortunately, the lack of donor livers makes it difficult to obtain enough viable human hepatocytes for hepatocyte-based therapies. Therefore, it is urgent to find new ways to provide ample hepatocytes. Induced pluripotent stem (iPS) cells, a breakthrough in stem cell research, may terminate these hinders for cell transplantation. For the promise of iPS cells to be realized in liver diseases, it is necessary to determine if and how efficient they can be differentiated into functional hepatocytes.

METHODSIn this study, we directly compared the hepatic-differentiation capacity of mouse iPS cells and embryonic stem (ES) cells with three different induction approaches: conditions via embryonic body (EB) formation plus cytokines, conditions by combination of dimethyl sulfoxide and sodium butyrate and chemically defined, serum free monolayer conditions. Among these three induction conditions, more homogenous populations can be promoted under chemically defined, serum free conditions. The cells generated under these conditions exhibited hepatic functions in vitro, including glycogen storage, indocynine green (ICG) uptake and release as well as urea secretion. Although efficient hepatocytes differentiation from mouse iPS cells were observed, mouse iPS cells showed relatively lower hepatic induction efficiency compared with mouse ES cells.

RESULTSMouse iPS cells would be efficiently differentiated into functional hepatocytes in vitro, which may be helpful in facilitating the development of hepatocytes for transplantation and for research on drug discovery.

CONCLUSIONWe demonstrate that mouse iPS cells retain full potential for fetal liver development and describe procedures that facilitates the efficient generation of highly differentiated human hepatocyte-like cells from iPS cells in vitro.
