Objectives:To observe the role of combined use of early micro feeding and intravenous nutrition in low birth weight(LBW) infants. Methods:Fifty four cases of LBW infants were randomly divided into two groups.Early micro feeding and intravenous nutrition were given in one group(EF & IN group) and another group(Control group) was given only with intravenous nutrition.The times of intravenous nutritional support requirement and hospital stay,the increase in body weight and the changes in serum bilirubin,lipids and creatinine were compared between the two groups. Results:The times of intravenous nutritional support and hospital stay were shortened and the body weight was increased in EF & IN group. The levels of serum bilirubin and creatinine and the serial concentrations of lipids on the day 7 and 14 after birth were significantly lower than those in control group. Conclusions:The combination of early,micro feeding and intravenous nutrition is superior to the only use of intravenous nutrition in shortrenning the critical course,increasing the body weight,beginning the oral intake and decreasing the possible injuries from total parenteral nutrition.

Objective To explore the mechanism of intrauterine growth restriction (IUGR) via observing the change of mitochondria in IUGR placenta. Methods Placenta samples were collected from 30 singleton pregnancies at the time of elec-tive caesarean section. Fifteen of them were appropriate for gestational age and 15 were IUGR. Mitochondrial morphology was observed by transmission electron microscopy, DNA copies were analyzed by real-time quantitative PCR and membrane potential was assayed by lfow cytometry. Results Signiifcant morphological changes of placental mitochondria were observed under transmission electron microscopy in IUGR, mitochondrial DNA copies in IUGR placenta were signiifcantly increased (P<0.01) and membrane potential decreased dramatically (P<0.01). Conclusions It is suggest that impaired mitochondrial function in IUGR may involve in IUGR pathogenesis.

HEK293 or HeLa cells were transfected by NIRF and, or P53, whole cell extracts andimmunoprecipitates were subjected to SDS-PAGE followed by Western blotting. GST pull-down was carried outto identify the interactions between NIRF and P53. In vitro ubiquitination reaction was carried out to identify P53ubquitinate by NIRF. The results suggested that NIRF could interact with P53 in vivo and in vitro. The results alsoshowed that NIRF could ubiquitinate P53 in vivo and in vitro. The results indicated that NIRF would be a newnegative regulator of P53.

This investigation describes a new precise, sensitive and accurate stereoselective RP-HPLC method for determination of the enantiomers of a novel alpha- and beta-receptor blocking agent, 1-[4-(2-methoxyethyl) phenoxy]-3-[[2-(2- methoxyphenoxy) ethyl]amino]-2-propanol (TJ0711), in rat plasma. GITC was used for precolumn derivatization of TJ0711 enantiomers. Enantiomeric resolution was achieved on a Eurospher-100 C18 column (250 mmx4.6 mm ID, 5-mum particle size), with UV detection at 255 nm, and the mobile phase consisted of acetonitrile and water (58:42, v/v) containing 0.02% glacial acetic acid (v/v). Using the chromatographic conditions described, TJ0711 enantiomers were well resolved with mean retention time of 10.2 and 11.5 min, respectively. Linear response (r>0.999) was observed over the range of 0.125-12.5 mug/mL of TJ0711 hydrochloride enantiomers. The mean relative standard deviation (RSD%) of the results of within-day precision was [Symbol: see text] 10%. The proposed method was found to be suitable and accurate for the quantitative determination of TJ0711 enantiomers in rat plasma, and it can be used in pharmacokinetic studies.

Objective To evaluate the effects of delayed cord clamping (DCC) on preterm infants with gestational age ＜32 weeks.Methods Literatures from January 1,1990 to April 30,2013 in Cochrane library,PubMed,EMBASE,China Academic Journal Network Publishing Database,Wanfang Medical Database and VIP Database were searched.Randomized controlled trials (RCT) of DCC in preterm infants with gestational age ＜32 weeks were screened and evaluated.DCC was defined as cord clamping in 30-90 s after delivery,and early cord clamping (ECC) (＜30 s) was as the control.Rev Man 5.1.0 was used for statistical analysis.Mean difference (MD) and 95％CI were used for continuous data while OR and 95％CI were for categorical data.Results Nine studies (11 articles) involving 373 infants were included.Compared with ECC,DCC improved hematocrit (MD=4.19,95％CI:2.97-5.40,Z=6.74,P＜0.000 01),blood volume (MD=11.70,95％CI:6.02-17.38,Z=4.04,P＜0.0001) and mean arterial pressure of preterm infants with gestational age ＜32 weeks (MD=3.11,95 ％CI:1.30-4.92,Z=3.37,P=0.0008),decreased the usage of volume expansion for hypotension (OR=0.32,95％CI:0.11-0.98,Z=2.05,P=0.04) and the incidence of necrotizing enterocolitis (OR=0.48,95％CI:0.25-0.92,Z=2.22,P=0.03).Meanwhile,DCC had no influence on the peak bilirubin concentration,the incidence of sepsis,patent ductus arteriosus,retinopathy and intracranial hemorrhage,also no influence on neonatal mortality on dcscharge,mental developmental index and psychomotor developmental index at seven-month old.Conclusions DCC might be a safe procedure to improve prognosis of preterm infants less than 32 weeks' gestational age.However,due to small sample size and lack of data on follow up,it is necessary to launch clinical trials with higher quality and larger scale to further evaluate the effect and safety of DCC.

Objective To evaluate the predictive accuracy of several risk-assessment strategies to predict the risk of significant neonatal hyperbilirubinemia, and to establish the best prediction model.Methods The transcutancous bilirubin (TcB) levels of 4907 term and near-team infants were measured.Trace blood bilirubin levels of the infants whose TcB levels ≥250 μmol/L were detected. Clinical data of newborns and their mothers were collected and were analyzed with Logistic regression model to investigate its correlation with signifrcant hyperbilirubinemia. Clinical high risk factors of significant neonatal hyperbilirubinemia were determined. Accuracy of three prediction methods for significant hyperbilirubinemia was compared by receiver operating characteristic (ROC) curve. The three methods included: whether predischarge bilirubin level (within 72 hours after birth) expressed in risk zone on an hour-specific bilirubin nomogram; clinical risk factors other than predischarge bilirubin level; and combination of the predischarge bilirubin risk zone and other clinical risk factors. Results Two hundred and eighty-six newborns (5.8%) were found with significant hyperbilirubinemia. The risk factors of significant neonatal hyperbilirubinemia were divided into three groups according to OR: (1) Major risk factors:predischarge (within 72 hours after birth) bilirubin level in the high risk-zone (OR=96. 39, 95% CI:53.32-174.27, P = 0. 000), large cephalohematoma (OR = 36.45, 95% CI: 10. 02-132.56,P=0. 0076), gestational age 35-36+6 weeks (OR= 30. 72, 95% CI 14.47-65.23, P=0. 0001) and exclusive breast feeding and weight loss was ＞9% of birth-weight (OR=22.44, 95% CI: 4.42-114. 03, P=0. 0016). (2) Minor risk factors: gestational age 37-37+6 weeks (OR=3.26, 95% CI:1.92-5. 55, P=0. 0232), predischarge bilirubin level in P76-P95(OR=13. 64, 95% CI: 8. 10-22.97,P=0. 0001) and bruising (OR = 2.32, 95% CI: 1.14-4.71, P = 0. 0497). (3)Protective factors (those factors associated with decreased risk of hyperbilirubinemia): predischarge bilirubin level in low-risk zone (≤P40) (OR=0. 00), gestational age ≥40 weeks (OR=0.21, 95% CI: 0.09-0.44,P=0. 0402) and mixed breeding (OR=0. 75, 95% CI: 0. 58-0.95, P=0.0059). The area under the ROC curve of predischarge bilirubin level was 0. 8687 and 0. 7375 for clinical risk factors other than predischarge bilirubin level. The area under the ROC curve of a combination of the predischarge bilirubin risk zone and additional clinical risk factors was 0. 9367. Conclusions The risk of significant neonatal hyperbilirubinemia could be simply and accurately predicted by infant's predischarge bilirubin level and the combination of predischarge bilirubin level, and clinical risk factors might improve the accuracy of prediction significantly.

Objective To systematically evaluate the effectiveness of delayed cord clamping (DCC) in term infants. Methods The data of the Cochrane library, PubMed, EMBASE, CNKI , VIP, Wanfang from 1 January 1970 to 30 April 2013 were searched. Randomized controlled trials (RCT) of DCC in term infants were included.RevMan 5.1.0 was used in the statis-tical analysis. Results Ten studies involving 1623 participants were included. Meta-analysis based on included studies showed that:compared with immediate cord clamping (ICC), DCC improved the hemoglobin levels at birth (MD=2.19, 95%CI:0.36, 4.02) and increased the incidence of polycythaemia (RR=2.87, 95%CI:1.24, 6.62). Compared with ICC, DCC showed no signi-ficant difference in the phototherapy for hyperbilirubinemia (RR=2.46, 95%CI: 0.93, 6.52), the hemoglobin levels within 6 months (MD=0.29, 95%CI:-0.17, 0.75), and the incidence of anemia (RR=0.71, 95%CI:0.45, 1.12). Conclusions DCC can improve the hemoglobin level in term infants after birth. However, the appropriate time of cord clamping has not been deter-mined. It is necessary to undertake further studies with higher quality and larger scale to evaluate the optimal time of cord clam-ping.

OBJECTIVETo observe the efficacy and safety of acupuncture therapy on moderate and severe allergic rhinitis via the comparison evaluation of western medicine.

METHODSSixty cases of moderate and severe allergic rhinitis were divided into an acupuncture group (30 cases) and a western medicine group (30 cases). In the acupuncture group, the main acupoints included Yingxiang (LI 20), Shangxing (GV 23), Fengchi (GB 20), Quchi (LI 11), Xuehai (SP 10), Feishu (BL 13), Geshu (BL 17), Pishu (BL 20), etc. The supplementary points were selected according to syndrome differentiation. In the western medicine group, budesonide nasal spray and cetirizine tablets were prescribed. All the cases were treated for 8 weeks in the two groups. Separately, before treatment, in 4 weeks and 8 weeks of treatment, the scores of clinical symptoms and physical signs were observed and the clinical efficacy and safety were compared between the two groups.

RESULTSIn 4 weeks and 8 weeks of treatment, the scores of symptoms such as sneezing, nasal discharge, nasal obstruction, nasal itching, eye itching and turbinate hypertrophy, the score of physical signs and total score were all reduced apparently as compared with those before treatment (all P<0. 05). The differences were not significant between the acupuncture group and the western medicine group (all P>0. 05). The total effective rates were 90. 0% (27/30) and 93. 4% (28/30) in the acupuncture group after 4 and 8 weeks of treatment, and were 76. 6% (23/30) and 80. 0% (24/30) in the western medicine group separately, without significant difference in comparison (all P>0. 05).

CONCLUSIONAcupuncture achieves the similar efficacy on moderate and severe allergic rhinitis as western medicine. It is the safe therapy and has no apparent adverse reactions.

Objective To observe the clinical effect of blood-pricking therapy combined with electroacupuncture in the treatment of migraine. Methods 70 patients with migraine who were admitted to Chengbei Branch of Hangzhou First People's Hospital from October 2015 to October 2016 were randomly divided into two groups: blood-pricking therapy combined with electroacupuncture group (observation group) and oral western medicine control group (western medicine group) respectively, with 35 cases in each group. The observation group was given pricking for bloodletting combined with electroacupuncture. The oral Western medicine control group was orally given ergotamine caffeine tablets and flunarizine for treatment, with the course of treatment of 12 days. Visual analogue scores(VASscores) 30 minutes after the end of the first treatment and headache scores at the end of the treatment period were observed. The difference of the efficacy of the two treatment methods was compared. Results The decrease value of VASscore in the observation group 30 minutes after the end of treatment was better than that in western medicine group(P＜0. 05). Before and after treatment, the decrease value of the headache scores and the total effective rate in the observation group were better than those in the western medicine group(P＜0. 05). The adverse reaction rate in the observation group was significantly lower than that in the western medicine group(P＜0. 05). Conclusion The combination of blood-pricking therapy and electroacupuncture and oral administration of western medicine both have a good immediate analgesic effect on migraine. However, the immediate analgesic effect and the short-term efficacy of blood pricking combined with electroacupuncture in the treatment of migraine are significantly better than those of oral administration of western medicine, and the safety is high, which is worthy of promotion.

Objective To explore the correlation between apparent diffusion coefficient(ADC)and neonatal behavioral neurological assessment(NBNA) of newborns with hypoxic ischemic encephalopathy (HIE),and to evaluate ADC in the early diagnosis of HIE from the imaging perspective. Method One hundred and nine neonates aged 0—7 days with HIE underwent conventional MRI and DWI. According to HIE grading standards, there were 43 neonates in the mild group, 38 in the moderate group, 28 in the severe group, and meanwhile 24 normal neonates with the same ages were selected as the control group. All cases were assessed with NBNA, and ADC values of bilateral frontal white matter, parietal white matter, periventricular white matter, posterior limb of the internal capsule(PLIC), ventral lateral nucleus of thalamus, lenticular nucleus, splenium of the corpus callosum, brainstem were measured. ADC values of different groups were compared by analysis of variance, and the correlations between ADC values of all ROIs and NBNA were analyzed by Pearson correlation. Results Except lenticular nucleus and the brainstem, ADC values of frontal white matter, parietal white matter, periventricular white matter and PLIC, ventral lateral nucleus of thalamus, splenium of the corpus callosum were decreased in the mild, moderate, severe group. In the mild, moderate, and severe group, the ADC values of frontal deep white matter were(1.82± 0.33)× 10-3,(1.77 ± 0.34)× 10-3 and(1.62 ± 0.31)× 10-3 mm2/s,while they were(1.81 ± 0.34)× 10-3,(1.79 ± 0.27)× 10-3 and(1.72 ± 0.31)× 10-3 mm2/s for the parietal deep white matter,(1.27 ± 0.15)× 10-3,(1.23 ± 0.12)× 10-3 and(1.15 ± 0.17)× 10-3 mm2/s for the periventricular white matter,(1.08 ± 0.09)× 10-3,(0.97 ± 0.07)×10-3 and(0.84±0.06)×10-3 mm2/s for the PLIC,(1.13±0.07)×10-3 ,(1.08±0.13)×10-3 and(1.00± 0.13)× 10-3 mm2/s for the ventral lateral nucleus of thalamus,(1.27 ± 0.22)× 10-3,(1.18 ± 0.16)× 10-3 and (1.00 ± 0.23)× 10-3 mm2/s for the splenium of the corpus callosum. There were statistically significant differences between the 3 groups (F=61.27,16.27, 23.26, 72.70, 26.73, 66.09,all P<0.05). In the mild, modreate and severe group, NBNA were(36.8 ± 1.4) in the mild group,(33.5 ± 1.6) in the moderate,and (29.3 ± 2.6) in the severe group. There was positive correlation between ADC values of frontal white matter, parietal white matter, periventricular white matter and PLIC, ventral lateral nucleus of thalamus, splenium of the corpus callosum and NBNA scores(r=0.60,0.49,0.54,0.67,0.56,0.65,all P<0.05). Conclusions There are correlations between ADC values of the related ROIs of HIE and NBNA scores. Combining two aspects might diagnose the brain injury of HIE more accurately and objectively.
