Objective To investigate the effect of ghrelin on PAI-1 secretion in HepG2 cells induced by TNF-αand the effect of p-38 MAPK.Methods HepG2 cells were cultured.The concentration of TNF-α used to treat the HepG2 cells wag selected.The effect of ghrelin on PAI-1 secretion induced by TNF-α was detected by ELISA,the p-38 MAPK expression was investigated by Western blot.Results The concentration of PAI-1 was increased when cells were exposed to different concentration of TNF-α.The p-p38 MAPK expression was increased when the cells were exposed to TNF-α,ghrelin could inhibit the increase of PAI-1 secretioN induced by TNF-α.The expression of p-p38 MAPK was decreased when the cells were pretreated with ghrelin.Conclusion PAI-1 secretion were increased after TNF-α in-creasing.Ghrelin could inhibit PAI-1 secretion via p38 MAPK.

ObjectiveTo investigate the protective effects and mechanism of ursodeoxycholic acid (UDCA) on α-naphthylisothi (ANIT)-induced cholestatic liver injury in rats.MethodsA total of 48 Sprague-Dawley (SD) rats were selected.Fouty-two rats were gavaged with ANIT (100 mg/kg) to induce acute liver injury,six rats were sacrificed 24 hours after the liver injury and the rats left were evenly divided into control group which were gavaged with saline and UDCA group which were gavaged with UDCA (20 mg/kg).Six rats were sacrificed at 48 hours,72 hours and 96 hours after modeling.The six untreated rats were set as blank control group.Serum and liver tissues of all rats were kept after sacrificed.Serum levels of alanine transaminase (ALT),aspartate transaminase (AST),total bilirubin (TBil) and total bile acid (TBA) were tested,interleukin-10 (IL-10),interleukin-6 (IL-6),and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA).The expression of multidrug resistance associated protein2 (Mrp2) at mRNA level in liver tissue was measured by quantitative real-time polymerase chain reaction (qRT-PCR) and the inflammatory reaction activity of liver tissues was inspected with Haematoidin-Eosin (HE)staining under microscope.ResultsAt 48 hours after liver injury modeling,serum TBil (143.80± 12.08) μmol/L vs.(178.50±15.19) μmol/L,TBA (13.15±3.81) μmol/L vs.(21.68±7.93)mol/L,IL-10 (44.13±3.68,37.15±6.25 ng/L),IL-6(50.80±2.09,57.32±4.63 ng/L) and TNF-α (17.53±0.84) ng/L vs,(19.10±1.64) ng/L of UDCA group and control group were compared,and the differences were statistically significant (P ＜ 0.01 or P＜ 0.05).At 72 hours after liver injury modeling,serum ALT (721.67±97.54) U/L vs.(929.50±148.29) U/L and IL-10 (54.68±6.79)ng/L vs.(43.85±4.08) ng/L of UDCA group and control group were compared,and the differences were statistically significant (P＜0.01 or P＜0.05).At 96 hours after liver injury modeling,serum ALT (156.83±14.99) U/L vs.(250.67±42.29) U/L,AST (143.67±27.45) U/L vs.(206.00±63.94) U/L and TBil (23.53±5.08) μmol/L vs.(34.02±9.98) μmol/L of UDCA group and control group were compared,and the differences were statistically significant (P＜0.01 or P＜0.05).The differences of Mrp2 expression at mRNA level in liver tissues between UDCA group and control group at 48 hours (0.77 ± 0.21,0.46 ± 0.25),72 hours (2.27 ±0.84,1.10 ±0.38) and 96 hours (3.64±0.54,2.75±0.69) after liver injury modeling were statistically significant (P＜0.01 or P＜0.05).ConclusionThe mechanism of the protective effects of UDCA on ANIT-induced liver injury may be related with the regulation of serum cytokines and liver Mrp2 expression.

A liquid chromatography-quadrupole-time-of-flight mass spectrometer(LC-Q/TOF-MS) based urinary metabolomic approach was employed to assess the toxicity-alleviation effect of Huangqi oral solution(HOs) on cisplatin-exposed rats and explore its possible mechanisms. Rat toxicity model was developed by multiple intraperitoneal injection of low-dose cisplatin, while HOs was orally administrated to rats simultaneously for 16 consecutive days to attenuate or reduce the cisplatin-induced toxicity. 24-hour urine samples on day 18 were collected and analyzed using LC-Q/TOF-MS to obtain the dataset of urinary metabolites. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed to assess the quality of the dataset and screen the potential toxicity-alleviation biomarkers. The serum level of rat creatinine and urea nitrogen on day 20 was determined, and the results showed that successive administration of HOs significantly reduced the cisplatin-induced increase of creatinine and urea nitrogen. PCA cluster analysis clearly demonstrated that HOs could partly improve the CDDP-induced abnormality of metabolic profiling. 35 urinary metabolites were finally screened as the potential biomarkers associated with the toxicity-attenuation effect of HOs, according to the combination of the analysis results of OPLS-DA, t-test and fold change analysis. Further metabolic pathway analysis revealed that HOs could restore the metabolic disorders of amino acid, energy and nucleotide, thereby exerted its toxicity-alleviation effect.

AIM:To examine the expression profiles of both genes and proteins in hippocampus of rats with temporal lobe epilepsy(TLE)for revealing the molecular mechanisms of TLE and looking for the candidate targets and new therapeutic approaches in clinical practice.METHODS:Rat temporal lobe epilepsy was induced by administration of lithium chloride and pilocarpine(LiCl-PILO).The expression spectra of genes and proteins were constructed through the techniques of cDNA microarray,two-dimensional(2D)electrophoresis and Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF MS).Subsequently,the differentially expressed genes and proteins were identified and analyzed.RESULTS:There were 192 genes of differential expression observed in hippocampal tissues of LiCl-PILO-induced temporal lobe epilepsy,and 159 genes have been registered in Genbank database,in which 84 genes were up-regulated while 75 genes were down-regulated.78 protein spots of differential display were screened out,in which 31 proteins were detected to be down-regulated and 47 were up-regulated.Finally,5 proteins were identified.CONCLUSION:These genes and proteins found in our study may play pivotal roles in the pathogenic mechanisms of epilepsy and may promise new therapeutic targets for refractory epilepsy in the future.

Objective To introduce the concept of long length finger reconstruction and our corresponding three operative methods. Methods In a series of 10 finger defect cases with one of their long finger amputated at or proximal to proximal phalanx, long finger reconstruction were accomplished with one of the three methods. First method: For emergency patients whose proximal finger segment were demolished, the donor second toe was transplanted intercalatedly with microsurgical technique between the original proximal finger stump and the saved distal finger segment. Second method: Bilateral second toes were harvested and connected together to form a long transplant in order to reconstruct a normal length finger. Third method: From one foot, the donor second toe is harvested with its dorsal and plantar skin flap. From the other foot, the second toe is harvested with its metatarsophalangeal joint and skin flaps from neighbouring sides of great and third toes. The skin covering will be perfect. During transplantation of the proximal transplant, the MPJ should be fixed at 90°plantar rotation position for better flexion. Results Uneventful survival of reconstructed fingers were obtained in all ten cases. Postoperative functional evaluation of the patients with standard set by Chinese Society of Hand Surgery showed to be excellent in 1 case, good in 5 cases and fair in 4 cases. The overall excellent/good rate was 60%. Conclusion By application of these three reconstruction methods, the challenging problem of long length finger can be solved to reasonable extent.

Objective:To analyze the levels of arachidonic acid (AA)and docosahexaenoic acid (DHA)in the breast milk of lactating mothers in Changchun City of Jilin Province, and to explore their influence factors. Methods:The lactating mother’s basic information was collected with questionnaire, and the breast milk of lactating mothers on postpartum 22-25 d was obtained and the 3-day 24-hour dietary recall method was used to investigate the dietary intake information of 514 healthy lactating mothers.The Food Composition Table of China 2009 was used to calculate the intakes of five kinds of polyunsaturated fatty acids (PUFAs) in diet of lactating mothers and the gold key nutrition expert system software for corresponding nutrient analysis was used to calculate the amount of various kinds of foods in the lactating mothers’daily diet.The levels of AA and DHA in breast milk were determined with gas chromatography and the linear regression was used to analyze the related factors of AA and DHA levels in breast milk.Results:①The average concentration of AA in breast milk of 514 lactating mothers was (0.08±0.04)g·100 g-1,and the average concentration of DHA was (0.05±0.04)g·100 g-1. ②The single factor correlation analysis results showed that the oil intake was both positively correlated with AA and DHA levels in milk of lactating mothers (r= 0.360,r=0.354,P<0.001),while the intakes of linoleic acid (LA), alpha linolenic acid (ALA),eicosapentaenoic acid (EPA),DHA,dairy and meats and seafood in diet were both negatively correlated with AA (r= -0.321,r=-0.280,r=-0.255,r=-0.299,r=-0.196 ,r=-0.306,P<0.05)and DHA (r=-0.315,r=-0.279,r=-0.175,r=-0.189,r=-0.248,r=-0.142,P<0.05).③The linear regression analysis results showed regression equation that dairy intake (β=-0.265)and EPA intake (β=-0.144)were both negatively correlated with the level of AA (P=0.009),and dairy intake was also negatively correlated with the level of DHA (β=-0.233,P<0.001).Conclusion:The AA and DHA levels in breast milk of lactating mothers didn’t increase with the increasing of intake of milk or dairy products in the study.Moreover there is a competitive relationship between n-6 and n-3 series polyunsaturated fatty acids in the process of metabolism.

Objective To investigate the association between rs2281951 and rs3798753 in ELOVL fatty acid elongase2 (ELOVL2 gene)and the docosahexenoic acid (DHA)level in breast milk,and to clarify the influence of the polymorphisms of ELOVL2 gene in the DHA level of breast milk.Methods 209 healthy maternals were selected and signed the consent form and completed the 3-day 24-hour dietary recall questionaire on one day during the 22nd-the 25th day after partum,and 20 mL breast milk was collected.The DHA level in breast milk was detected with gas chromatography.The milk DNA was extracted and two single nucleotide polymorphisms (SNPs) of ELOVL2 gene were detected by Sequenom Mass Array System. UNPHASED 3.012 genetics software was adopted to analyze the quantitative trait of haplotype and the DHA level in breast milk.Results The distribution of genotypic frequencies of rs2281591 and rs3798713 sites in ELOVL2 gene was consistent with Hardy-Weinberg equilibrium (P > 0.05).The dietary fatty acid intakes and the milk DHA levels of maternals carrying different genotypes had no statistically significant differences (P > 0.05 ). The DHA levels in breast milk of maternals carring different rs3798713 (CG)-rs2281591 (AG)haplotypes had no statistically significant difference (χ2 =3.422,df =5,P =0.635).Conclusion Rs3798713 and rs2281951 and constructed haplotypes in ELOVL2 gene are not related to the DHA levels in breast milk.

Three hundred cerebrovascular disease (CVD) patients (disease onset <3 days) were evaluated for serum C-reactive protein (CRP) level at admission, and Scandinavian Stroke Scale (SSS) or Oxford Handicap Scale (OHS) at baseline and 3 months. Based on serum CRP levels, the participants were divided into group A [CRP(1.20 ±0.35)mg/L], group B[CRP(4.98 ± 1.08) mg/L] or group C[CRP (19.34±12.27)mg/L]. Our results showed that serum CRP level was positively correlated with SSS (r = 0.39 or0.43, both P<0.01) and OHS (r=0.40 or0.42, both P<0.01) at3 months. Thus, evaluating serum CRP level within 3 clays of disease onset might be helpful in predicting clinical outcomes of CVD patients.
