ObjectiveTo investigate the effects of grape seed proanthocyanidin extracts (GSPE) on advanced glycation end product receptor (RAGE),NF-Κb and connective tissue growth factor (CTGF) in the myoeardium of diabetic rats.MethodsTotal 30 streptozotocin (STZ) induced diabetic rats were randomly divided into 2 groups:diabetic group (DM1,n-15) and GSPE (250 mg/ kg,i.g) treated diabetic group (DM2,n= 15).Another two control groups:normal rats(C1,n= 10)and normal rats treated with GSPE (250 mg/kg,i.g) (C2 group,n= 10) were also observed.After 24 weeks,blood was collected to measure fasting plasma glucose (FBG) and RAGE.The protein expression of NF-Κb was determined in myocardial tissue by immunohistochemical staining and Western blot.The protein expressions of RAGE and CTGF were measured by Western blot.Results The levels of FBG and RAGE were significantly higher in diabetic rats than in control rats (P＜0.05).After GSPE treatment,RAGE level significantly reduced (P＜0.05),but FBG had no change in diabetic rats.The protein expressions of RAGE,NF-Κb and CTGF in the myocardial tissue of diabetic rats had marked increase compared with control rats (P＜ 0.05),however,their levels significantly reduced after GSPE treatment (P＜0.05).ConclusionsGSPE may protect diabetic rats against cardiomyopathy,possibly by decreasing the protein expressions of RAGE,NF-Κb and CTGF.

The β-Glucuronidase gene (sbGUS) cDNA firstly from Scutellari abaicalensis leaf was cloned by RT-PCR, with GenBank accession number KR364726. The full length cDNA of sbGUS was 1 584 bp with an open reading frame (ORF), encoding an unstable protein with 527 amino acids. The bioinformatic analysis showed that the sbGUS encoding protein had isoelectric point (pI) of 5.55 and a calculated molecular weight about 58.724 8 kDa, with a transmembrane regions and signal peptide, had conserved domains of glycoside hydrolase super family and unintegrated trans-glycosidase catalytic structure. In the secondary structure, the percentage of alpha helix, extended strand, β-extended and random coil were 25.62%, 28.84%, 13.28% and 32.26%, respectively. The homologous analysis indicated the nucleotide sequence 98.93% similarity and the amino acid sequence 98.29% similarity with S. baicalensis (BAA97804.1), in the nine positions were different. The expression level of sGUS was the highest in root based on a real-time PCR analysis, followed by flower and stem, and the lowest was in stem. The results provide a foundation for exploring the molecular function of sbGUS involved in baicalcin biosynthesis based on synthetic biology approach in S. baicalensis plants.

Objective To explore the value of Gd-EOB-DTPA enhanced magnetic resonance imaging (MRI) in the quantitative evaluation of liver function.Methods Between June 2012 and June 2013,we prospectively included 8 patients with cirrhosis and 6 patients with primary hepatic carcinoma (PHC).The Child-Pugh classification,indocyanine green retention rate at 15 minutes (ICGR15),and Primovist enhanced MR imaging were performed in all the patients.Using the deconvolution method to calculate hepatic extraction fraction (HEF),the correlations between HEF and Child-Pugh and ICGR15 were analyzed.Results For cirrhosis,there was a significant correlation between the HEF and the ICGR15 by the Pearson correlation coefficient (r =-0.971,P ＜ 0.05).For hepatocarcinoma,there was also a significant correlation (r =-0.855,P ＜ 0.05).The average HEF of PHC was 21.80％ (14.89％ ～ 35.90％).Conclusions The Gd-EOB-DTPA enhanced MRI accurately evaluated liver function quantitatively.It may be used for patients with PHC for preoperative examination.

Objective To investigate the clinical,endoscopic and pathologic features in the differential diagnosis between Crohn' s disease (CD) and intestinal tuberculosis (ITB).Methods The complete clinical data of 107 patients with CD and 69 patients with ITB in our hospital from January 2011 to January 2012 were retrospectively analyzed.The diagnostic value of the clinical and endoscopic scoring system was evaluated.Results CD occurred mainly in male.The salient features of CD included long duration of disease high incidence of colectomy.Comparing with patients with ITB,patients with CD have more cases of diarrhea,hematochezia,abdominal mass,intestinal obstruction,intestinal hemorrhage,perianal lesions,and extraintestinal manifestations (all P ＜ 0.05).It's more frequent to have positive results of anti-Saccharomyces cerevisiae antibody (ASCA),perinuclear antineutrophil cytoplasmic antibody (pANCA) and fecal occult blood in CD patients,as well as low albumin,high C-reactive protein (CRP),elevated platelet count and hematocrit (P ＜ 0.05 or P ＜ 0.01).The salient features of ITB included low fever,night sweats,active parenteral tuberculosis,increased erythrocyte sedimentation rate (ESR),chest X-ray abnormalities,the positive PPD (purified protein derivatives tuberculin) and T-SPOT (P ＜ 0.05 or P ＜0.01).Based on the imaging,CD often involved the small intestine,such as the intestinal stricture and abdominal abscess (P ＜ 0.05),while mesenteric lymphadenopathy was more common in ITB (P ＜ 0.05).The endoscopic examination showed that some patterns of disease involvement such as fissure-shape ulcer [41.12％ (44/107) vs 5.80％ (4/69)],cobblestone sign [15.89％ (17/107) vs 4.35％ (3/69)],lesions over four segment [24.30％ (26/107) vs 7.25％ (5/69)],rectum involvement [17.76％ (19/107) vs 5.80％ (4/69)],ileocecal valve stenosis [21.50％ (23/107) vs 8.70％ (6/69)] and mucosal bridge [5.61％ (6/107) vs 0(0/69)] were more frequent in CD patients than those in ITB patients(P ＜ 0.01 or P ＜0.05).However circular ulcers[37.68％ (26/69) vs 9.35％ (10/107)],rat-bite-like ulcers[24.64％ (17/69) vs 12.15％ (13/107)],persistent open ileocecal valves [39.13％ (27/69) vs 19.63％ (21/107)],tuberous and polypoid lesions [36.23％ (25/69) vs 20.56％ (22/107),37.68％ (26/69) vs 22.43％ (24/107)] were more common in ITB (P ＜ 0.01 or P ＜ 0.05).In terms of pathological findings,certain characteristic features such as transmural inflammation [5.61％ (6/107) vs 0 (0/69)],fissure-liked ulcers [14.02％ (15/107) vs 4.35％ (3/69)],non-caseous granulomas [5.61％ (6/107) vs 0(0/69)],lymphoid hyperplasia [16.82％ (18/107) vs 5.80％ (4/69)] and crypt abscess [9.35％ (10/107) vs 1.45％ (1/69)] were more common in CD than those in ITB(P ＜ 0.05).According to the clinical and endoscopic scoring system,the positive diagnostic rate of CD was 50.47 ％ (54/107)and of ITB was 66.67 ％ (46/69) (P ＜ 0.05).Conclusions The differential diagnosis between CD and ITB should be considered carefully based on clinical,endoscopic,pathological characteristics.The clinical and endoscopic scoring system may contribute to distinguish CD and ITB.

Objective To study the changes of cytokines in children with hand-foot and mouth disease.Methods Sixty-two cases of hand-foot-mouth disease admitted to our hospital from March 2011 to December 2011 were included in this study.Thirty-seven cases were male and 25 cases were female,the youngest one was four month old,and the oldest one was eleven month and 4 years old,the average age was (1.56 ± 0.98) years old.Sixty-two children with hand-foot-mouth disease were devided into ordinary group (n =20),severe group (n =20),critically ill group (n =22).Twenty healthy children served as control group.The plasma levels of pro-inflammatory cytokines [tumor necrosis factor(TNF)-α,interleukin(IL)-1β、IL-6] and anti-inflammatory cytokines (IL-1 0、IL-13、IL-4) were detected.Results The pro-inflammatory and anti-inflammatory cytokines of patients with hand-foot and mouth disease were increased compared with control group.The levels of TNF-α in severe and critically ill groups were (201.45 ± 133.42) ng/L,(220.37 ± 117.54)ng/L respectively,which significantly increased compared with ordinary group [(118.12 ±11205) ng/L] (P ＜0.05).The levels of IL-1β and IL-6 in critically ill cases were (651.77 ±538.45) ng/L and (88.02 ±50.76) ng/L respectively,which significantly increased compared with severe cases [(551.75 ± 252.75) ng/L,(59.25 ± 28.80) ng/L] and ordinary cases [(270.18 ± 249.79) ng/L,(55.76 ± 28.68) ng/L] (P ＜ 0.05).The level of IL-10 was (137.53 ± 72.07) ng/L in ordinary cases,which increased significantly compared with the severe and critically ill cases[(57.07 ±55.02) ng/L,(73.37 ±56.01) ng/L] (P ＜0.05).The levels of IL-13 were (507.53 ±210.86) ng/L and (489.67 ± 168.99) ng/L in severe and critically ill cases respectively,which significantly increased compared with ordinary cases [(387.16± 157.43) ng/L] (P ＜0.05).The levels of IL-4 showed no significant differences among the ordinary,severe and critically ill groups(P ＞ 0.05).Conclusion The pro-and anti-inflammatory cytokines were involved in inflammatory response simultaneously in patients with hand-foot and mouth disease.The increases of TNF-α,IL-1β and IL-6 are consistent with severity of the disease,while factor IL-10,IL-13 are decreased as the severity of the disease.The increase of the pro-inflammatory cytokines and decrease of the anti-inflammatory cytokines are the important sign of the exacerbation.

Objective To observe the changes of hospitalization rates of patients with goiter in Lianyungang City in a coastal area with mild iodine deficiency in 2002-2010.Methods Medical reports of patients with goiter from county hospitals were studied at county level with a retrospective method.In accordance with the National Iodized Salt Monitoring Program,nine townships(towns) were taken from each county (district) [total of five counties(districts)]; four villages were selected from each township (town); salt samples were taken from eight households in each village,and salt iodine was determined using direct titration of sodium thiosulfate.Results The hospitalization rate of patient with goiter increased from 1.87/10 million in 2002 to 7.05/10 million in 2009,and then fluctuated to 6.06/10 million in 2010(x2 =281.91,P＜ 0.01).Among them,female's hospitalization rates were significantly higher than that of male 's(The variation range of x2 values were 35.23-116.04,all P ＜ 0.01),and the hospitalization rates of people over the age of 40 years were significantly higher than that of people less than 40 years of age(The variation range of x2 values were 33.04-263.04,all P ＜ 0.01),and the hospitalization rates of people in urban areas were significantly higher than that of people in rural areas (The variation range of x2 values were 18.35-140.00,all P ＜ 0.01).Average salt iodine was 27.61-30.13 mg/kg in 2002-2010.The coverage rate of iodized salt and the consumption rate of qualified iodized salt both increased year by year (x2 =183.75,211.99,P ＜ 0.01).There was a positive correlation between hospitalization rate of patient with goiter and coverage rate of iodized salt(spearman correlation coefficient was 0.83,P ＜ 0.05).There was a positive correlation between hospitalization rate of patient with goiter and the consumption rate of qualified iodized salt too (spearman correlation coefficient was 0.93,P ＜ 0.05).Conclusions In Lianyungang City,the hospitalization rate of patient with goiter,the coverage rate of iodized salt and the consumption rate of qualified iodized salt all show upward trend in 2002-2010.The relationship among them is worth further study.
