ObjectiveTo investigate the effects of the asphyxia as a Second Hit on renal function during early stage after birth in small for gestational age (SGA) infants.MethodsThe infants who were hospitalized within 24 hours after birth in Peking University Third Hospital between January 2013 and March 2015 were retrospectively enrolled, and divided into different groups depending on gestational age and asphyxia history. There were 40 preterm non-asphyxia SGA infants and 80 controls who were preterm non-asphyxia appropriate for gestational age (AGA) infants; 11 preterm asphyxia SGA infants and an equal number of preterm asphyxia AGA infants as controls; 33 term non-asphyxia SGA infants and 33 term non-asphyxia AGA infants as controls; and four term asphyxia SGA infants and 13 term asphyxia AGA infants as controls. Blood urea nitrogen (BUN), serum creatinine (SCr), and estimate glomerular filtration rate (eGFR) were tested within 48 h after admission and the incidence of abnormal indexes was compared between groups byt-test and Fisher exact test.Results(1) Compared with preterm non-asphyxia AGA group, BUN level significantly decreased in preterm non-asphyxia SGA group [(3.99±1.69) vs (5.11±2.08) mmol/L,t=2.948, P=0.004]. Compared with term non-asphyxia AGA group, term non-asphyxia SGA group had higher SCr level [(72.03±10.29) vs (62.58±12.27)μmol/L,t=3.390,P=0.001] and lower eGFR level [(25.19±4.07) vs (33.99±8.75) ml/(min·1.73 m2),t=5.238,P=0.000]. (2) Compared with preterm non-asphyxia AGA infants, preterm asphyxia AGA infants had higher BUN [(6.96±3.09) vs (5.11±2.08) mmol/L,t=2.602,P=0.011] and SCr [(76.45±10.11) vs (66.70±13.18)μmol/L,t=2.357,P=0.021] and lower eGFR level [(15.86±2.31) vs (19.54±5.08) ml/(min·1.73 m2),t=2.361,P=0.020]. Compared with preterm non-asphyxia SGA group, there was a significant increase in BUN level [(6.70±3.37) vs (3.99±1.69) mmol/L,t=2.581,P=0.025] and decrease in eGFR level [(14.80±4.67) vs (18.66±5.03) ml/(min·1.73 m2),t=2.285,P=0.027] in preterm asphyxia SGA group. Changes in term infants were similar to preterm infants. (3) Compared with asphyxia AGA group, asphyxia SGA group showed a higher frequency of abnormal eGFR in term infants (4/4 vs 4/13, Fisher exact test,P=0.029). ConclusionsAsphyxia as a probable Second Hit can influence the renal function during early stage in both preterm and term infants, especially in SGA infants.

Objective To explore the value of contrast-enhanced FLAIR imaging in diagnosis of leptomeningeal metastasis.Methods 23 cases of leptomeningeal metastasis with definite primitive-tumour were collected.All the cases were confirmed by clinic and laborotary examination.Of the 23 cases,7 cases underwent contrast-enhanced T1WI only,16 case underwent contrast-enhanced T1WI and FLAIR.Two groups were analyzed comparatively in diagnostic accuracy and displaying lesions between images of two sequence.Results(1)2 cases were missed,and 1 case was unsure diagnosed in T1WI contrast group;16 cases were all diagnosed accurately in both T1WI and FLAIR contrast-enhanced group.(2)11 cases with fine linear enhancement and 7 cases with small nodular enhancement were more obviously on contrast-enhanced FLAIR than that on contrast T1WI,but the thick linear enhancement were equal on two sequence.4 cases with more lesions were displayed on contrast-enhanced FLAIR images.The signal intensity on contrast FLAIR images were higher than that on contrast T1WI images at the same lesions.Conclusion Contrast-enhanced FLAIR has important value in diagnosing leptomeningeal metastasis.

Objective To investigate the roles of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway and its regulatory protein peroxisome proliferator-activated receptor γ (PPAR γ) and phosphatase and tension homologue deleted on chromosome 10 (PTEN) in regulating insulin sensitivity in rats with fetal growth restriction (FGR).Methods Sixteen pregnant rats were randomly divided into two groups including FGR and control groups on the 12th day of pregnancy (eight in each group).The FGR group was given low protein diet (8％ of casein) and restriction diet to establish the neonatal rat model of FGR.All maternal rats after delivery and newborn rats after weaning on 21 days after born were fed with normal diet.Each time blood samples were collected from eight newborn rats of each group to measure levels of fasting plasma glucose (FPG) and fasting insulin(FINS) at the time points of 21 days,two and four months after birth.Then insulin resistance index (IRI) and insulin sensitivity index (ISI) were calculated to evaluate insulin sensitivity.Expression of PI3K,AKT,PPAR γγ,PTEN and glucose transporters 4 (GLUT4) in skeletal muscle at mRNA and protein levels were measured at 21 days,two and four months after birth with real time fluorescence polymerase chain reaction and Western blot,respectively.Relationships between the expression of key molecules of PI3K/AKT signaling pathway and insulin sensitivity were analyzed.T-test,and Pearson's correlation analysis were used for statistical analysis.Results (1) The average birth weight of newborn rats in the FGR group was lower than that of the control group [(4.37± 0.69) vs (7.03±0.55) g,t=-20.75,P＜0.05].The incidence of FGR in the FGR group was 93.33％ (70/75).(2) Compared with normal offspring,those in the FGR group showed significantly increased FPG [two months after birth:(5.53± 0.58) vs (7.49 ± 0.38) mmol/L,t=8.08;four months afterbirth:(6.35±0.66) vs (8.94±0.90) mmol/L,t=6.58],FINS [two months afterbirth:(9.18±0.66) vs (14.67± 1.90) mU/L,t=7.71;four months after birth:(33.08±2.76) vs (56.33±2.81) mU/L,t=16.71] and IR1 (two months after birth:2.25±0.31 vs 4.90±0.81,t=8.63;four months after birth:9.30±0.90 vs 22.44±3.10,t=1 1.51),but decreased ISI (two months after birth:0.020 ± 0.002 vs 0.009± 0.001,t=-10.1 4;four months after birth:0.005±0.000 vs 0.002 ±0.000,t=-14.91) at two and four months after birth (all P＜0.05).(3) Compared with normal offspring,those in the FGR group showed decreased expression of PI3K (21 days after birth:0.082±0.028 vs 0.019±0.004,t=-6.29;two months after birth:0.020±0.003 vs 0.010±0.005,t=-4.78;four months after birth:0.014±0.004 vs 0.003±0.001,t=-7.87) and GLUT4 (21 days after birth:0.132±0.057 vs 0.041 ±0.019,t=-4.32;two months after birth:0.183±0.084 vs 0.069±0.017,t=-3.74;four months after birth:0.248±0.069 vs 0.113±0.040,t=-4.74) at mRNA level at 21 days,two and four months after birth (all P＜0.05).Compared with normal offspring,decreased expression of PPAR γ (two months after birth:0.028±0.002 vs 0.012±0.005,t=-3.70;four months after birth:0.030±0.008 vs 0.012±0.005,t=-3.80) and increased expression of PTEN (two months after birth:0.020±0.004 vs 0.045±0.014,t=5.09;four months after birth:0.023±0.007 vs 0.034±0.009,t=2.57) at mRNA level were observed in offspring of the FGR group at two and four months after birth (all P＜0.05).(4) Compared with normal offspring,expression of PI3K protein (21 days after birth:0.22±0.01 vs 0.17±0.02,t=-6.62;two months after birth:0.27±0.03 vs 0.16±0.02,t=-7.25;four months after birth:0.18±0.01 vs 0.09±0.02,t=-9.79) and GLUT4 protein (21 days after birth:0.21 ±0.01 vs 0.03±0.01,t=-27.29;two months after birth:0.10±0.01 vs 0.06t±0.01,t=-3.90;four months after birth:0.13 ±0.01 vs 0.08± 0.02,t=-8.10) decreased in offspring in the FGR group at 21 days,two and four months after birth (all P＜0.05).Compared with normal offspring,those in the FGR group showed decreased expression of PPAR γ protein (two months after birth:0.10 ± 0.01 vs 0.07± 0.01,t =-7.29;four months after birth:0.09±0.01 vs 0.08±0.01,t=-2.83),but increased expression of PTEN at protein level (two months after birth:0.10±0.01 vs 0.15±0.02,t=6.01;four months after birth:0.09±±0.01 vs 0.13±0.02,t=5.51) at two and four months after birth (all P＜0.05).(5) The IRI levels in offsprings in the FGR group were negatively correlated with the expression of PI3K,GLUT4 and PPAR γ at protein level (two months after birth:r=-0.90,-0.92 and-0.79;four months after birth:r=-0.92,-0.75 and-0.73,all P＜0.05),but positively correlated with the expression of PTEN at protein level (r=0.87 and 0.86,both P＜0.05) at two and four months after birth.Conclusions The abnormal expression of the key molecules of PI3K/AKT signaling pathway precedes the decrease of insulin sensitivity in newborn rats with FGR and the expression regulatory protein PPAR γ and PTEN are also changed,suggesting that these molecules may induce the impairment of insulin sensitivity in rats with FGR and be involved in the development of insulin resistance.

Objective:To extract, separate and identify the flavonoids in Humulus Scandens and detect their cytotoxic effect on cells HepG2. Methods: After Humulus scandens bing was extracted by alcohol, luteolin-7-O-β-D-glucoside ( LGL) and cosmoiin ( AGL) were obtained by using column chromatography and identified by spectral analysis. The inhibitory effects of LGL and AGL on HepG2 cells were detected by a typan blue dye method. Results:The main flavonoids in Humulus Scandens were LGL and AGL. When the concentration of LGL and AGL was increased from 6. 25 μmol·L-1 to 100. 0 μmol·L-1 , the inhibition rate of LGL was increased from 28. 8% to 95. 2% and that of AGL was increased from 3. 6% to 21. 3%. Conclusion: LGL has notable inhibitory effect on HepG2 cells in a dose-dependent manner, while the inhibitory effect of AGL is not obvious.

OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.
