International Journal of Pediatrics 2011;38(4):316-318
Late preterm is labeled near term. As developmental immaturity, there was higher morbidity in late preterm infants compared with term infants. Especially brain injury, a 3-fold increased risk of cerebralpalsy and significantly higher rates of developmental delay and mental retardation for late preterm infants compared with term infants. In addition, a higher rates of neonatal complications had been documented on late preterm infants. These problems included apnea, hypoglycemia, hyperbilirubinemia, respiratory distress syndome, and poor feeding. It was known that long-term impact of these diseases will result in brain injury.

Chinese Journal of Practical Nursing 2008;24(15):56-57
Objective To investigate the influence of psychological intervention on the anxiety of patients with obstructive jaundice and supply theoretical reference for psychological evaluation and nutsing.Methods 129 patients with obstructive jaundice was divided into the intervention group(64 cases)and the control group(65 cases).The control group adopted routine treatraent method such as anti-infection,liver protection treatment,enhancement of coagulation mechanism and supporting treatment.The intervention group received psychological nursing,relaxation training and distraction of attention based upon routine nursing.The degree of anxiety and pruritus was obseved and recorded in the two groups.Results The degree of anxiety in the intervention group was evidently lower than that of the control group(P<0.01).The degree of pruritus in the intervention group was 18.75%,which was statistically different from that of the control group(35.38%),P<0.05.Condusion Adoption of psychological intervention could effectively reduce the degree of anxiety and pruritus of patients with obstructive jaundice.

Herald of Medicine 2016;35(5):514-517
Objective To develop a double-wavelength HPLC method for the simultaneous determination of neogambogic acid,gambogic acid,( +)-catechin and L-epicatechin in Litong pill. Methods The quantitative analysis was carried out on C18 column(250 mm×4.6 mm,5 μm).A linear elution of methanol-acetonitrile(4: 1)and 0.2% phosphoric acid solution was adopted at the flow rate of 1.1 mL·min-1 ,with the detection wavelength set at 360 nm for neogambogic acid and gambogic acid,and at 280 nm for(+)-catechin and L-epicatechin. Results The linear ranges of neogambogic acid,gambogic acid,(+)-catechin and L-epicatechin were 5.85-117.00 μg·mL-1(r= 0.999 5),8.95-179.00 μg·mL-1(r= 0.999 8),6.90-138.00 μg·mL-1(r= 0.999 7),and 5.30-106.00 μg·mL-1(r = 0.999 9),respectively.The average recoveries were 97.82%(RSD= 1.21%),98.72%(RSD = 1.30%),96.96%(RSD = 0.84%)and 99.26%( RSD = 1.46%)for neogambogic acid, gambogic acid,(+)-catechin and L-epicatechin,respectively. Conclusion The method is simple,accurate,reproducible and may be used for the simultaneous determination of neogambogic acid,gambogic acid,(+)-catechin and L-epicatechin in Litong pill.

China Pharmacy 2017;28(7):912-915
OBJECTIVE:To establish a method for the concentration determination of indigo in rats'plasma,and study the pharmacokinetic characteristics in rats in vivo. METHODS:18 rats were randomly divided into low-dose,medium-dose,high-dose groups,6 in each group,which were intragastrically administrated 10,20,40 mg/kg of indigo solution. The sample blood 0.3 mL was taken from eye socket before administration and 0.083,0.25,0.5,0.75,1,2,4,6,8,10,12,16,24,48,72 h after ad-ministration,separating the plasma,then LC-MS/MS was used to determine the plasma concentration of indigo after methanol pre-cipitation. The column was Agilent Poroshell EC-C18 with mobile phase consisting of methanol-5 mmol/L ammonium acetate solu-tion(95:5,V/V)at a flow rate of 0.4 mL/min;multiple reaction monitoring was conducted for the quantitative analysis,with ion pair of 263.1-218.8 (indigo) and 237.2-194.1 (carbamazepine,internal standard). Pharmacokinetic parameters were calculated by DAS 3.0 software. RESULTS:The linear range of indigo was 0.5-100 ng/mL(r=0.9999),intra-day and inter-day RSDs were low-er than 9%(n=5);matrix effects of low,medium and high does quality control samples were (98.25 ± 3.71)%,(102.23 ± 2.64)%,(102.29±3.79)%(n=5). The pharmacokinetic parameters of indigo in low-dose,medium-dose,high-dose groups were tmax of(8.6±1.1),(9.2±0.8)and(9.5±0.8)h;cmax of(30.9±8.6),(44.9±10.1),(96.1±17.4)ng/mL;t1/2 of(14.9±2.1), (16.3±2.9),(15.3±3.7)h;AUC0-72 h of(366.6±83.4),(694.9±105.8),(1223.42±108.7)ng·h/mL,respectively. CONCLU-SIONS:The method shows high sensitivity,good specificity,and can be used for the content determination of indigo in plasma samples of rats. The pharmacokinetics of indigo in rats in vivo fits non-compartment model.
7.Advances in signaling pathways of pancreatic cancer
Chinese Journal of Clinical Oncology 2015;(14):724-727
Pancreatic cancer has a very poor prognosis, with a five-year survival less than 5%. Nowadays, to improve the treat-ment efficacy of pancreatic cancer has been a highlight for medical researchers worldwide. Increasing knowledge about the molecular pathogenesis of the disease has shown that genic mutations, such as oncogene Kras2, and anti-oncogenes Cdkn2a, and TP53, are hall-marks of pancreatic cancer. Therefore, it is vital to deeply understand the pathogenetic mechanism of pancreatic cancer and find new therapeutic strategies to cover it. In this review, we summarized the recent advances in the signaling pathways of pancreatic cancer.

Chinese Journal of Postgraduates of Medicine 2014;37(27):39-41
Objective To study the risk factors and clinical features on acute hepatic dysfunction induced by sepsis.Methods One hundred and sixty-eight patients with sepsis were divided into 2 groups according to liver function:simple sepsis group (control group,142 cases) and acute hepatic dysfunction induced by sepsis group (observation group,26 cases).The biochemical indicators,plasma endothelin (ET)-1,sepsis-related organ failure assessment (SOFA) were compared between 2 groups.The risk factors of inducing acute hepatic dysfunction were analyzed.Results The incidence of acute hepatic dysfunction in 168 patients with sepsis was 15.5% (26/168).The total bilirubin,direct bilirubin,creatinine,range of blood glucose variation,arterial blood lactic acid,plasma ET-1,SOFA,fatality rate in observation group were significantly higher than those in control group [(35.9 ±9.8) μμmol/L vs.(27.8 ±6.7) μmol/L,(17.7 ± 8.0) μ mol/L vs.(12.3 ± 5.9) μ mol/L,(219.6 ± 156.4) μ mol/L vs.(159.4 ± 125.3) μ mol/L,(7.6 ±4.9) mmol/L vs.(3.0 ± 1.6) mmol/L,(3.8 ± 1.3) mmol/L vs.(2.0 ± 1.2) mmol/L,(79.6 ±25.7)μg/L vs.(60.8 ± 12.6) μg/L,(8.8 ±2.6) scores vs.(5.7 ± 1.8) scores,38.5% (10/26) vs.17.6%(25/142)],there were statistical differences (P < 0.01 or < 0.05).Multifactor Logistic regression analysis results showed that long-term drinking,cardiac insufficiency and hypotension were independent risk factors of acute hepatic dysfunction induced by sepsis.Conclusions The arterial blood lactic acid,plasma ET-1 and SOFA in patients with acute hepatic dysfunction induced by sepsis are higher.Long-term drinking,cardiac insufficiency and hypotension are the risk factors of acute hepatic dysfunction induced by sepsis.
