Objective To discuss the relation between level of Hs-CRP and glycometabolic disturbance in patients with acute coronary syndrom. Methods 155 patients with acute coronary syndrome were divided into 3 groups according to the WHO standard of diabetes diagnosis,normal glucose tolerance group(group A,44 cases),impaired glucose tolerance group(group B,60 cases),diabetes group(group C,51 cases). All cases were checked by the 75g glucose tolerance test, blood Glucose, insulin, HbA1c,lipid,hypersensitive C reaction protein(hs-CRP). 95 patients were checked by coronary angiography(CAG). Statistic comparison were measured among three groups including the levels of hs-CRP,insulin,HbA1c,lipid and coronary artery lesions. Results The levels of Hs-CRP,PBG, FINS, PINS,HbA1c,TC,LDL-C in both group B and C were higher than those in group A;The levels of TG,PINS were not found significant differences between group B and C. The level of Hs-CRP was correlated with the levels of PBG,PINS,HbA1c,TC,LDL-C. The coronary artery lesions showed by CAG in group B and C were more severe than those in group A,coronary multivessel changes in group B and C were more frequent than in group A,it had no significant difference between group B and C.Conclusion Compared with the patients of normal glucose tolerance, patients with glycometabolic disturbance have higher levels of hs-CRP,their coronary artery lesions are more severe.

To explore the individual roles of G protein β and γsubunit in the interactions with effectors. Methods We investigated the interactions of Gβ1 and Gβ1γ2 with adenylyl cyclase Ⅱ(ACⅡ) us ing the yeast two-hybrid and three-hybrid systems. Results When assayed for the abilities to activate the reporter gene, the interactions among AD-β1, γ2 and BD-AC ⅡQ in the three-hybrid system were more po tent than the interactions between AD-β1 and BD-AC ⅡQ in the two-hybrid system. The expressions of BD-AC ⅡQ and AD-β1 in transformants coexpressed AD-β1 and BD-AC ⅡQ, and transformants coexpressed AD-β1, γ2 and BD-AC ⅡQ were respectively detected. The comparisons between the reporter activity and the expression levels of BD-AC ⅡQ and AD-β1 in the yeast cells show there was no correlations, i.e.The difference in the reporter activity was not a reflection of differential expression level of the hybrid pro teins. Conclutions All these results suggest that G protein β1 subunit is sufficient to maintain the basic in teraction between Gβ1γ2 and AC ⅡQ, and γ2 subunit plays an important role in the high affinity interaction of Gβ1γ2 with ACⅡQ.

Objectives:The present study was undertaken to investigate the effects of recombinant growth hormone(rhGH) on protein metabolism during intraabdominal infection.　 Methods : The study was made up of two parts: animal experiments and clinical studies. All animals were divided into three groups: normal control, sepsis control and rhGH therapy groups. All patients were divided into two groups: infection control and rhGH therapy groups. Expressions of hepatic albumin mRNA and muscle myosin heavy chain mRNA were detected.　 Results: In septic animals, rhGH accelerated nitrogen retention and recovery of body weight, improved concentrations of plasma albumin and muscle protein. Expressions of hepatic albumin mRNA and myosin heavy chain mRNA decreased significantly after infection. By using rhGH, expression of albumin mRNA and myosin heavy chain mRNA increased obviously. In clinical study, plasma concentrations of albumin, prealbumin and transferrin were higher than infectious controls after rhGH administration.　 Conclusions: rhGH improved nitrogen balance and protein synthesis of liver and muscle during sepsis .More studies were needed to determine weather rhGH was an effective metabolic intervention method during sepsis.

Objective To detect the level of plasma miR-155 in patients with pancreatic cancer and evaluate its diagnostic value for pancreatic cancer. Methods Sixty-two cases of pancreatic cancer patients, 61 patients of chronic pancreatitis and 36 normal controls were included in the study. miR-155 in the total RNA extracted from the plasma was measured using real time PCR. The diagnostic parameters and relationship of the miR-155 with clinical characteristics in pancreatic cancer patients were analyzed. Results The relative abundance of plasma miR-155 in pancreatic cancer, chronic pancreatitis and normal controls were 5.41 ±3.14,2.59 ±2.49 and 0.77 ± 1.17, and the value was significantly higher in pancreatic cancer group compared with those of chronic pancreatitis and normal group (P ＜ 0. 01 ). No significant correlation between the level of plasma miR-155 and age, sex, tumor size in pancreatic cancer patients was found. But there was a negative correlation between the level of plasma miR-155 and TNM staging (r = -0. 323, P = 0.01 ). For discriminating pancreatic cancer from normal control, the AUC ROC of miR-155 was 0. 943 (95% CI 0.902-0.985), and the sensitivity and specificity were 87.1% and 83.3%, respectively. For discriminating pancreatic cancer from chronic pancreatitis, the AUC ROC of miR-155 was 0.762 (95% CI0. 678-0. 846),and the sensitivity and specificity were 64.5% and 73.8%, respectively. For discriminating pancreatic cancer from chronic pancreatitis and normal, the AUC-ROC of miR-155 was 0. 829(95% CI0. 767-0.892), and the sensitivity and specificity were 62.9% and 84.5%, respectively. Conclusions Plasma miR-155 was significantly increased in patients with pancreatic cancer, and can be used for diagnosis of pancreatic cancer.

Objective: To examine expression patterns of focal adhesion kinase (FAK) and its activated form, phosphorylated FAK (pFAK),in human osteosarcoma and to investigate the correlation of FAK expression with clinicopathological parameters and prognosis. Functional consequence of manipulating FAK protein levels was also investigated in human osteosarcoma cell lines. Methods: Immunohistochemical staining was used to detect FAK and pFAK levels in pathologically archived materials from 113 patients with primary osteosarcoma. Kaplan-Meier survival and Cox regression analyses were used to evaluate prognoses. The role of FAK in cytological behavior of MG63 and 143B human osteosarcoma cell lines was studied via the FAK protein knockdown with siRNA. Cell proliferation, migration, invasiveness, and apoptosis were assessed using cell counting kit-8, Transwell, and Annexin V/PI staining methods. Results: Both FAK and pFAK were overexpressed in osteosarcoma patients. Tumor cells exhibited cytoplasmicity and occasional membranous immunoreactivity for FAK. A total of 42 cases (37.17%) mainly showed expressed pFAK in cytoplasm of osteosarcoma cells. No overexpression staining of anti-FAK and anti-pFAK antibodies was observed in normal cancellous bone tissues or negative controls. Significant differences were observed in overall survival between FAK-/pFAK- and FAK+/pFAK- groups (P=0.016), FAK+/pFAK- and FAK+/pFAK+ groups (P=0.012), and FAK-/pFAK- and FAK+/pFAK+ groups (P<0.001). All groups showed similar metastasis-free survival. Cox proportional hazard analysis showed that FAK expression profile is an independent indicator of both overall andmetastasis-free survival. siRNA-based knockdown of FAK significantly reducedmigration and invasion of MG63 and 143B cells and affected proliferation and apoptosis in osteosarcoma cells. Conclusion: Osteosarcoma malignancies in vitro and in vivo were correlated with overexpression and phosphorylation of FAK. These findings suggest that FAK plays an important biological role in osteosarcoma carcinogenesis. This study provides a better understanding of diagnostic and prognostic relevance of FAK overexpression and phosphorylation in osteosarcoma patients. Therefore, FAK and pFAK can be used as independent predictors of overall and metastasis-free survival in osteosarcoma patients.

Objective To determine the frequency of polymorphism at exon 26 (C3435T) of muhidrug resistance 1 gene (MDR1) in epileptic patients in the southern Chinese and to study the association of this polymorphism with pharmacoresistance.Methods DNA samples were obtained from 134 patients,of whom 72 were resistant to antiepileptic drug treatment and 62 were responsive to the treatment. Genotypes of the C3435T polymorphism were determined by polymerase chain reaction (PCR) followed by restriction digestion and gel electrophoresis.Genotype and allele frequencies in the drug resistant group were compared to those in the response group by Chi-square analysis.Results Of all 134 patients,33 (24.6%) had CC genotype,72 (53.7%) had CT genotype,and 29 (21.6%) had TT genotype.The frequency of CC genotype was significantly higher in the pharmaeoresistance group (33.3%) than that in the responsive group (14.5%,P=0.012).The frequency of the C allele was also significantly higher in the pharmacoresistance group (57.6%) than that in the responsive group (44.4%,P=0.03).When patients were divided by types of seizure into three groups:generalized seizure group,partial seizure group,and undefined seizure group,the CC genotype and C allele were associated with pharmacoresistance in the partial seizure group.Conclusions In the southern Chinese,the CC genotype and C allele are associated with resistance to the antiepileptic treatment.This finding needs to be verified in studies with larger sample size.
