Objective To investigate the recent prognosis of stress hyperglycemia for the emergency percuta- neous coronary intervention(PCI)with ST-segment elevation acute myocardial infarction(AMI).Methods 410 pa- tients treated by emergency PCI were chosen.According to a history of diabetes and blood glucose levels,they were randomly divided into four groups:group 1(n = 288):random blood glucose normal and non-diabetic patients;group 2(n = 30):random normal blood glucose in diabetic patients;group 3(n = 54):random plasma glucose level and non- diabetic patients;group 4(n = 38):high random plasma glucose level in diabetic patients.Age,gender,hospital within 24 hours with random glucose,glycated hemoglobin(HbA1c),peak creatine kinase,TIMI flow recovery and 30-day mortality of the patients were compared.Results Mortality of four groups were 4.2%,3.4%,7.5% and 5.9% re- spectively(P

Objective To investigate the effects of supplementing qi and activating blood circulation method(YQHX) on platelet inhibition rate and platelet membrane glycoprotein in elderly patients with unstable angina pectoris undergoing percutaneous coronary intervention(PCI).Methods Totally 177 elderly patients with unstable angina(qi deficiency and blood stasis syndrome) pectoris were randomized into two groups:90 cases in the treatment group and 87 cases in the control group.Both groups received conventional western medicinal treatment,for 14 days but YQHX was added to the treatment group.Platelet inhibition rate and platelet membrane glycoprotein were measured before and 14 days after treatment.Results After 14 days of treatment,the platelet inhibition rates induced by arachidonic acid (AA) and adenosine diphosphate (ADP) were significantly increased in the treatment group in comparison to pre-treatment and to control group respectively(P＜0.01).The prevalence of aspirin and clopidogrel resistance were lower in the treatment group than in the control group(8.9％ vs.21.8％,11.1％ vs.25.3％,both P＜0.05).After 14 days of treatment,the expression rates of CD62p,CD63 and PAC-1 were significantly lower in the treatment group than in pre-treatment and control group respectively (P＜0.01).Conclusions YQHX might effectively inhibit the platelet function and reduce the prevalence of aspirin and clopidogrel resistance in elderly patients with unstable angina pectoris undergoing the percutaneous coronary intervention.

Objective To investigate the inhibition of low-dose aprotinin on systematic inflammatory response during cardiopulmonary bypass. Methods Twenty-eight ASA Ⅱ-Ⅲ patients(male 13, female 15) undergoing valve replacement were studied. The age ranged from 27 to 55 years and body weight from 37 to 70 kg. CPB time ranged from 66 to 218 mm and aortic cross clamping time from 30 to 140 min . The patients were divided into two groups: control group(n=14) and aprotinin group(n = 14) Premedication included intramuscular phenobarbital sodium 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with intravenous midazolam 0. lmg/kg, fentanyl 20-30?g/kg and vecuronium 0. 1-0. 12mg/kg, and maintained with intermittent bolus injection of fentanyl and vecuronium supplemented with isoflurane inhalation. In aprotinin group aprotinin 1?106KIU was infused after induction of anesthesia until thoracotomy, after thoracotomy aprotinin was infused at a rate of 2.5? 106 KIU/h and aprotinin 2. 5 ?106KIU was added to the prime fluid as suggested by Levy. Blood samples were obtained before anesthesia, before CPB and 1h and 24h after CPB for determination of CD11b and CD18 expression on the surface of neutrophil by immunofluoresence flow cytometry. Results The expression of CD11b or CD18 and CPB time were positively correlated(?= 0.644, 0.538, P0.05). 1 h after CPB CD11b/ CD18 expression increased significantly in the control group and was significantly higher than that in the aprotinin group, but at 24h after CPB only CD11b expression in control group was significantly higher than that in aprotinin group. In aprotinin group there was no significant difference in CD11b/CD18 expression between the four intervals.Conclusions CPB-induced systematic inflammatory response may be positively correlated with CPB time. Low dose aprotinin can inhibit the increase in CD11b/CD18 expression after CPB.

Objective: To clone hGLP-1 cDNA in the pBS SK(+/-)vector and construct the expression vector of pGEX-4T-3/hGLP-1cDNA to express GST-hGLP-1 fusion protein. Methods: The hGLP-1 cDNA was constructed by 6 synthetic oligonucleotides fragments, followed by the procedure of annealing and ligation with oligonucleotides fragments. The hGLP-1 cDNA was cloned into the pBS SK(+/-) vector, and was selected by α-complementation. It was confirmed by DNA sequening, then inserted into the MCS of the fusion expression vector pGEX-4T-3. The recombinant vector was transformed into E. coli TG1. Results: The recombinant plasmid DNA was digested with restrictive endonuclease BamHⅠand XhoⅠ. The result demonstrated that the hGLP-1 cDNA was successfully inserted into the pGEX-4T-3 vector and fusion protein GST-hGLP-1 had been expressed in SDS-PAGE. Conclusion： Expression of GST-hGLP-1 fusion protein can provide foundation for obtaining a larger quantity of recombinant hGLP-1 for experimental and clinic studies.

Objective To explore the diagnostic value of MRI on fetal congenital limb deformities.Methods Sixteen pregnant women,aged from 22 to 40 years (average 29 years) and with gestation from 22 to 39 weeks (average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies. Acquisitions consisted of coronal, sagittal, and axial slices relative to the fetal brain, spine, thorax, abdomen, especially limbs using 2D FIESTA sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses (4 fetuses) or autopsy (12 pregnant women,13 fetuses). Postnatal evaluation included US, MR imaging, computed tomography, and physical examination. Results Of the sixteen pregnant women (15 with a single fetus and 1 with twin fetuses) ,17 fetuses were found. Those limb deformities of sixteen pregnant women included congenital both upper extremities amelia (1 case), sirenomelia sequence (1 case), micmmelia (5 cases, 1 of which were twins),bilateral clenched hands (2 cases), right pelydactyly (1 case), simple right ectrodactyly (1 case), right dactylolysis(1 case), simple club foot (2 cases), hydrocele spinalis with club foot (2 cases), 1 of the 2 cases with bilateral clinodactyly. In 14 of 16 cases, the diagnoses established by MR imaging were correct when compared with postnatal diagnosis, and prenatal MR diagnosis was inaccurate in 2 cases. Conclusion Prenatal MRI is effective in the assessment of congenital limb deformities of fetuses, it can yield information additional to that obtained with US, and further correct US diagnosis.

ObjectiveTo investigate the expression of TESTIN gene in endometrial carcinoma and explore the functions of this gene in tumor development and progression.MethodsqRT-PCR and immunochemical staining assay were used to determine the mRNA and protein level of TESTIN in the tumor tissues,and the relationship between TESTIN expression and clinical pathology characteristics was analyzed.Results Compared to normal tissue,76.5％ (52/68) tumor tissues showed TESTIN reduced ( P ＜ 0.01 ),furthermore,this reduction in the subgroup of endometrioid adenocarcinoma was significant,but it was rarely observed in the subgroup of serous papillary adenocarcinoma.ConclusionsTESTIN was obviously down regulated in endometrail carcinoma,especially in endometrioid adenocarcinoma,which indicated TESTIN played an important role in tumorigenesis of uterine.

Objective To explore the possibility of differentiation of mesenchymal stem cells isolated from patients with hepatocirrhosis into hepatocyte-like cells induced by EGF and HGF and to lay basis for transplanted autologous bone marrow MSCs in treatment of liver disease at terminal stage.Methods Bone marrow cells were obtained from volunteers with liver cirrhosis.MSCs were separated by density gradient centrifugation and were cultured through adhere culture.MSCs were cultured in DMEM medium with HGF,EGF,HGF+EGF or no growth factor.The phenotypes of MSCs were identified by flow cytometry,immunohistochemistry,and Albumin levels in culture supernatants were determined by ELISA.Results Growth and division of adherent cells obtained from the patients with hepatocirrhosis were good and the phenotypes of MSCs were CD29 positive and CD34 negative.The shape of MSCs changed from long fusiform to polygonal or round on 21th-28th days in grow factor induced groups.Immunocytochemical analysis for CK18 and AFP showed positive staining reaction for AFP on 7th day,for CK18 on 21st and 28th day in grow factor induced groups with MSCs-induced Alb production increasing in a time-dependent manner.No markers of hepatocyte linear cells were detected in no growth factor induction group.Conclusion Both HGF and EGF can induce mesenchymal stem cells to differentiate hepatocyte-like cells alone or coordinately.

We wished to understand the genetic characteristics of enteric cytopathic human orphan (ECHO) virus type 6 (ECHO6) circulating in China. First, the partial VP1 coding region of six strains of the ECH-O6 virus isolated from cases of hand, foot and mouth diseases during routine surveillance in Hunan Province (China) from 2009 to 2014 were sequenced. Those sequences were analyzed along with 138 sequences of ECHO viruses covering five provinces of China and countries outside China retrieved from the GenBank database. A phylogenetic tree based on partial VPI was constructed, and it indicated that Chinese strains of the ECHO virus could form two distinct evolutionary branches: branch 1 and branch 2. All isolates of the ECHO virus from Hunan Province belonged to the 2c subranch, which revealed that they may share a common evolutionary origin. ECHO strains in branch 2 may be the predominant strains in China due to their wide geographic distribution and long period of circulation. We used nucleotide differences of >30%o as the basis of cluster division. ECHO, viruses could be divided into four clusters (A-D). Cluster D could be divided further into ten subclusters on the basis of nucleotide differences of 15%-30%. All ECHO6 isolates from Hunan Province belonged to the D7 subcluster. These data showed that the ECHO6 strains that circulated in Hunan Province in 2009-2014 were closely related to each other, and probably shared a common evolutionary origin. In addition, at least four distinct lineages of ECHO viruses have circulated in China.
