The changes of PAF activity and the effects of anisodamine (654-2) were studied in the superior mesenteric artery occlusion (SMAO)shock in rabbits. The results showed that plasma PAF activity increased from 3.88?0.82 AU/ml before SM-AO to 9.71?1.26 AU/ml (P

Objective This study was to explore a justifiable approach for the translation of traditional Chinese medicine (TCM) terms in the light of Skopos Theory and thus to provide references to the standardization of TCM terms.Methods By exploring the source and development of a TCM term Bi,we studied its connotation,compared available English versions and decided on the choice version.Results The word arthralgia,obstruction or impediment was found to be the most frequently used word in 12 recognized publications,more frequent than the transliteration of Bi.Conclusion It is suggested that an accurate and a complete understanding of TCM terms and English expressions are required prior to translating so that the faithfulness and accuracy of the translation are maintained for the sake of optimal approximation.

Objective To construct eukaryotic expression vector of human pancreatic duodenal homeobox 1(PDX-1) gene,and to detect its expression in NIH3T3 cell lines. Methods The whole coding sequence of PDX-1 gene was amplified by polymerase chain reaction(PCR) from human pancreatic-cell tumors cDNA.The fragment was inserted into eukaryotic expression vector pcDNA3.1 plasmid.The recombinant plasmid was verified by double digestion and DNA sequencing.The expression of PDX-1 gene in NIH3T3 cells was assayed by Western blot. Results The length of specific fragment amplified by PCR was 852 bp,and the recombinant plasmid pcDNA3.1-PDX-1 showed two bands of 5.5 kb and 852 bp by digestion using respective restriction enzymes BamHⅠand EcoRⅠ.The sequence of PDX-1 gene was approved or confirmed by blasting to GenBank.It was suggested that PDX-1 gene had been cloned into pcDNA3.1 vector correctly.Western blot showed that PDX-1 gene was expressed,which was detected 24 h after pcDNA3.1-PDX-1 plasmid was transfected into NIH3T3 cells. Conclusion The recombinant eukaryotic expression vector pcDNA3.1-PDX-1 was successfully constructed and expressed in NIH3T3 cell lines.

Objective To investigate the prevalence rate of new-onset malignant tumors in type 2 diabetes mellitus patients .Methods Type 2 diabetes mellitus patients ( 1771 cases ) over 3 years since May 2006 in Xinhua Hospital were retrospectively recruited .The prevalence and distribution of different tumors were analyzed .Results ⑴Total prevalence of malignant tumors was 2.88%, and more common in male ( P <0.05 ) .The prevalence of different malignant tumors in human systems from high to low were digestive, urinary, and respiratory .⑵Age-dependent analysis from <50, 50~, 60~, 70~,and≥80 showed that the prevalence were 0.73%,1.93%,3.27%,3.58%, and 5.02% respectively .A significant difference was found in them ( P <0.05 ) .Conclusion The prevalence of new-onset malignancies is higher in type 2 diabetes mellitus , which is associated with age and sex .Tumor screening should be strongly recommended in such a group of the patients for their earlier diagnoses and treatments due to the un -typical clinical manifestations .

Objective To obtain abundant human betacellulin(BTC) with biological activity. Methods The whole mature protein coding sequence of BTC gene was amplified by polymerase chain reaction(PCR) method applied to human pancreatic ?-cell tumors cDNA.The fragment was cloned into prokaryotic expression vector pET32a(+) plasmid.The recombinant plasmid was transformed into E.coli BL21 and the fusion protein was expressed under isopropyl-beta-D-thiogalactopyranoside(IPTG).The fusion protein was purified by Ni2+ affinity chromatography.SDS-PAGE and Western blot were employed to determine the expression and purification of the expected protein.BTC was added to culture NIH3T3 cells for 5 days,and cell proliferation was detected by MTT. Results Lots of fusion protein were produced,and the purified protein can stimulate the proliferation of NIH3T3 cells. Conclusion The human BTC can be successfully obtained from the pET32a(+) system with the biological activity of stimulating the proliferation of NIH3T3 cells.

Objective To explore the impact of advanced glycation end-products ( AGEs) on matrix metalloproteinase 2 ( MMP-2) expression in cultivated INS-1 cells. Method INS-1 cells were cultivated and MMP-2 expression was analyzed. Glycated serum was prepared for incubating with INS-1 cell. Reactive oxygen species (ROS) was detected by flow cytometry. The intracelluar MMP-2 expression was analyzed by RT-PCR, realtime PCR and Western blot. The MMP-2 cDNA was expressed in cultivated INS-1 cells. Result The level of ROS treated with AGEs was significantly higher than that in the control( P<0.05 ) , and the levels of MMP-2 and its protein expressions turned out as well( P<0. 05). Conclusion The results suggest that MMP-2 was expressed in INS-1 cells. Increased MMP-2 expression in ?cells may be induced by AGEs, suggesting that MMP-2 might play an important role in oxidative stress-mediated islet injury.

Objective To investigate the significance of total bilirubin/albumin in predicting bilirubin neurotoxicity.Methods Eighty-three cases with hyperbilirubinemia who treated from May 2007 to August 2010 were selected,the serum total bilirubin and albumin were detected and total bilirubin/albumin was calculated.According to brainstem auditory evoked potential(BAEP)results,the patients were divided into normal BAEP group and abnormal BAEP group and compared.Results There were 27 cases of abnormal BAEP group and 56 cases of normal BAEP group.Total bilirubin and total bilirubin/albumin in abnormal BAEP group were higher than those in normal BAEP group[(356.50±59.23)μmol/L vs.(318.70±55.12)μmol/L,(5.02±0.49)×10-3 vs.(4.56±0.43)×10-3],the differences were significant (P<0.05).Multiple regression analysis showed:abnormal BAEP was closely related to total bilirubin/albumin(r=0.72,P<0.05),whih abnormal BAEP was not obviously related to total bilirubin(r=0.19,P>0.05).Conclusion Total bilirubin/albumin can reflect serum unconjugated bilirubin level of neonatus with hyperbilirubinemia better than total bilirubin,and it can can be taken as one index to evaluate the risk factors of bilirubin neurotoxicity.

One case with fulminant type 1 diabetes during the third trimester of pregnancy was reported.If a patient manifests abrupt onset of hyperglycemia,nausea,vomiting,and bellyache during pregnancy or immediately after delivery,fulminant type 1 diabetes should be considered.

Objective To investigate the effect of a novel isoflavone compound(F11) on the plasma lipid and cholesterol of the ovarectomied rat.Methods Female SD rats at age of 3 months old were randomly divided into 6 groups,that is,sham operation group(Sham),normal saline group(2 ml/d),estradiol group(E2,50 ?g?kg-1?d-1),and 3 F11 groups(15,50,150 mg?kg-1?d-1).Besides the Sham group,the ovary of the rats from other groups were resected,and received the injection as above mentioned.All rats were killed 10 weeks later,and their plasma lipid,total cholesterol,LDL,HDL,and body weight and uterine weight were measured.Results The plasma lipid,total cholesterol,LDL,HDL were significantly different in normal saline group and 4 treatment group(P
