Objective:To study the relationship among serum uric acid (SUA)level,brachial-ankle pulse wave veloci-ty (baPWV)and severity of coronary disease.Methods:A total of 121 inpatients,who hospitalized in our depart-ment of cardiology from Jan 2011 to Jul 2012,were enrolled.According to results of coronary angiography,they were divided into coronary heart disease (CHD)group (n=59)and normal control group (n=62),CHD group was further divided into single vessel coronary disease group (n=30,single vessel group),double-vessel coronary disease group (n=14,double-vessel group)and multi-vessel coronary disease group (n=15,multi-vessel group).SUA level and baPWV were compared among all groups,and their relationship with degree of coronary disease was analyzed. Results:SUA concentration gradually rose along with number of diseased coronary vessels increased,it's (349.26± 96.58)μmol/L,(400.37±70.96)μmol/L,(517.57±85.26)μmol/L and (602.60±77.03)μmol/L in normal con-trol,single vessel,double-vessel and multi-vessel group respectively,P<0.05 or <0.01;baPWV gradually rose a-long with number of diseased coronary vessels increased,compared with normal control group,there was significant increase in baPWV [(1499.04±193.82)cm/s vs.(1885.32±319.73)cm/s,(2036.00±406.40)cm/s,(2171.03± 348.53)cm/s]in single vessel,double-vessel and multi-vessel group,that of double-vessel group was significantly higher than that of single vessel group,P<0.05~<0.01.Logistic regression analysis indicated that SUA and baP-WV were independent risk factors for CHD morbidity (OR=13.011,14.008,P=0.000).Conclusion:Serum uric acid level and pulse wave velocity possess important clinical application value for predicting CHD and its severity.

Objective To analyze the effect of different procedures of alimentary reconstruction for the digestive and absorptive functions of patients after total gastrectomy. Methods From January 2012 to January 2013,there were 114 patients with gastric cancer,of which 58 patients received Roux-en-Y anastomosis were the control group,56 patients received P-type jejunal loop esophageal jejunal Roux-en-Y anas-tomosis were the observation group,the nutritional status and postoperative complications of two groups were compared. Results The level of RBC,HGB,TP and ALB of the observation group were significantly higher than that of the control group(P<0. 05),the incidence rate of in-traoperative complications,diarrhea and reflux esophagitis of the two groups had no significant differences (P>0. 05),but the incidence rate of postoperative dumping syndrome and abdominal distension of the observation group were significantly lower than that of the control group (P<0. 05). Conclusion The efficacy of P-type jejunal loop esophageal jejunal Roux-en-Y anastomosis for gastric surgery was superior to Roux-en-Y anastomosis.

Angiopoietin family is a recently discovered type of cellular factors that specifically bind to the TIE-2 receptors located exclusively in endothelial cell membrane. The protein structures of this family members are similar. They can be structurally divided into three domains: an N-terminal region lacking homology to any known structures, an alpha-helical rich coiled-coil segment, and a fibrinogen-like domain. The distribution and biological activity of these factors are different in organism. Angiopoietin-1 as a agonist, mostly locates in close proximity with vascular endothelial cells, keeps the stability of blood vessels, enhances the affinity of vascular endothelial cells with surrounding cells and matrix, decreases the leakage of vessel. Ang-2 is a naturally occurring antagonist of Ang-1, exists in the angiogenic remodeling region and is related to the decrement of the stability of vessel. Ang-3 is widely distributed in multiple mouse tissues, while Ang-4 is expressed only in lung. Although Ang-3 and Ang-4 are structurally diverged from each other, they appear to represent the mouse and human counterparts of the same gene locus. Biological functions of Ang-3 and Ang-4 have not been elucidated yet. Angiopoietin family has potentially clinical applications for incurring illnesses which lead to vessel wound and vascular abnormal development.

Objective To detect the methylation status of DLEC1 promoter in the tissue and serum of colorectal cancer(CRC) patients and to evaluate its clinical relevance.Methods Genomic DNA was extracted from the tissues(cancer tissue and corresponding adjacent normal tissue) and sera of 71 CRC patients;serum genomic DNA was also obtained from 20 patients with benign gastrointestinal diseases and 20 healthy donors.Promoter methylation status of DLEC1 gene was detected by methylation-specific polymerase chain reaction(MSP).Results The incidence of aberrant methylation of DLEC1 promoter was 45.1%(32/71) in CRC tissues,which was significantly higher than that in the adjacent normal tissues(7.1%,4/56)(P

To explore the change in gene expressions of p38 mitogen-activated protein kinase (p38MAPK) and its upstream signal-regulated molecule (mkk3 and mkk6) in normal skin versus hypertrophic scars underlying its potentially biological significance. Total RNAs were isolated from 8 specimens of hypertrophic scars and 8 specimens of normal skin, then they were purified to mRNAs, and the gene expression of mkk3, mkk6 and p38MAPK was examined with reverse transcription-polymerase chain reaction (RT-PCR). The results showed that the intensities of gene expression of mkk6 and p38MAPK were weak in normal skins, while the expression of these 2 genes was significantly elevated in hypertrophic scars compared with normal skins (P0.05). In hypertrophic scar, the elevation of mkk6 and p38MAPK gene expression, which plays pilot roles in cell proliferation, may be one of the mechanisms controlling the formation of hypertrophic scars.

To investigate the effect of FGF-10 on the secretion of GM-CSF by adult keratinocytes in vitro and to understand the mechanisms involved in the stimulation of granulation tissue formation by FGF-10 during wound healing. Concentrations of FGF-10 used were 4, 16, 125 and 500 ng/ml. Cells were seeded in the amount of 2 500 cells/cm 2 or 5 000 cells/cm 2 in dishes in serum-free medium, and supernatants were collected at 24, 48 and 72 hours after culture. The amounts of GM-CSF in cell culture supernatants were determined using GM-CSF ELISA kits, and cell numbers were counted by haemocytometer. For cells seeded in low density (2 500 cells/cm 2), GM-CSF was not detected at 24 hours. At 48 hours, both in absolute concentrations and on a per-cell basis, the amounts of GM-CSF secreted in cultures with 125 and 500ng/ml FGF-10 were significantly higher than that in negative control (P0.05). At 48 hours, the keratinocytes in the middle area were confluent, and a number of cornified cells were observed, while the productions of GM-CSF in FGF-10 cultures were not higher than that in negative control. There was a clear negative correlation between the secretion production of the growth factor and the total cell number in each dish with a correlated coeffecient of 0.881 (P

Objective To study expression intensity and distribution of phosphorylated forms of extracellular signal-regulated protein kinase1/2 (ERK1/2), stress-activated protein kinase (SAPK) and P38MAPK in normal skin and hypertrophic scars and their potential biological significance. Methods The morphological characteristics of hypertrophic scars in different periods after wound healing and normal skin were examined histopathologically. Protein expression of p-ERK1/2, p-SAPK and p-P38MAPK was also assessed with immunohistochemical technique. Results In normal skin, phosphorylated forms of ERK1/2, SAPK and P38MAPK were mainly located in epidermal basal cells, in which the positive cellular rates of all the three proteins were low. Along with the maturation of hypertrophic scars, protein contents of p-ERK1/2 and p-SAPK were progressively increased. In mature hypertrophic scars, positive signals of these two proteins were mostly distributed in keratinocytes and some fibroblasts. The positive cellular rate of p-P38MAPK ascended in active hypertrophic scar, then decreased to a level which was still higher than that of normal skin. Conclusion The formation of hypertrophic scars may be associated with the alteration in signaling pathways which results in the increment of protein contents of p-ERK1/2, p-SAPK and p-P38MAPK.
