Objective: To investigate the effects of bovine plasma fibronectin on the proliferation and differentiation of rat osteoblasts. Methods:Rat osteoblasts were cultured and identified. AlamarBlue were used to determine the effect of various concentration of bovine plasma fibronectin on the proliferation of the osteoblasts. ELISA method was used to determine the alkaline phosphatase activity of the cells. Results: Fibronectin stimulated the proliferation of rat osteoblasts at 40 ?g/ml (P

Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Objective To evaluate the diagnostic value of urine Cystatin C(Cys C) for renal function impairment in neonates with hypoxic-ischemic encephalopathy(HIE).Methods The urine Cys C concentration was measured by enzyme linked immunosorbent assay(ELISA) in 47 cases of HIE newborns(25 cases were mild HIE and 22 cases were moderate-severe HIE) within 3 days after their birth.Twenty-three cases without perinatal asphyxia or other factors which could result in renal function impairment were selected as control group.Urine Cys C with urine retinal-bindingprotein(RBP),?2-microglobulin(?2-MG) and fractional sodium excretion(FENa%) were analyzed by kolmogorov-smirno in each group.Results Compared with control group,the concentration of urine Cys C,RBP and the levels of FENa% in HIE newborns were significantly elevated.The levels of urine Cys C in moderate-severe HIE newborns were significantly higher than those in mild HIE newborns(Pa

Objective: To examine the expression of glucocorticoid receptor in human colon cancinoma tis-sues and call lines and to explore the survival of colon cancer cell lines treated with dexamethasone alone or in combination with 5-Fu and L-OHP in a way of dexamethasone pretreatment or co-administration in vitro.Methods: The expression of glucocorticoid receptor was detected in 61 cases of colon cancer tissue samples and 4 types of colon cancer cell lines by immunohistochemistry. Apoptosis was detected by Hoechst33342 staining and flow cytometry. MTT assay was employed to detect the chemosensitivity of colon carcinoma cells to L-OHP and 5-Fu with dexamethasone pretreatment for 24 hours or co-administretion. Results: Positive GR expression was found in 57.3% colon cancer tissue samples and in Lovo and HCT-116 cell lines, not in HT-29 and SW-480. Apoptosis was detected in GR-expressed Lovo and HCT-116 cells at 72 hours after 1×10~(-4)mol/L Dex treatment, and the rates of apoptosis were higher than those in the control groups without Dex (P<0.01),GR-negative cells, HT-29 and SW-480 even treated with 1 × 10~(-4)mol/L Dex for 72 hours. Pretreatment and co-administration for Lovo cells with 1×10~(-4)mol/L Dex could decrease the IC50 of L-OHP from 13.7±1:1.3μg/mL to 5.9±0.6μg/mL and 4.8±0.7μg/mL, respectively. IC50 of 5-Fu was decreased from 72.2±8.1 μg/mL to 21.1±4.1μg/mL and 18.6±4.0μg/mL, respectively. Conclusion: There is expression of glucocorticoid receptor in part of colon carcinoma tissue samples and cell lines. Apoptosis does occur in GR-expressed Lovo and HCT-116 cells induced by dexamethasone in vitro. Pretreatment for 24h and co-administration with Dex can increase the chemosensitivity of Lovo cells to L-OHP and 5-Fu.

Objective To outline the research fronts of ten major sub-specialties in internal medicine.Methods Based on their impact factor scores and the proportion of the journals of 10 subspecialties (endocrinology & metabolism,cardiac & cardiovascular systems,hematology,infectious diseases,nephrology,gastroenterology & hepatology,respiratory system,rheumatology,critical care medicine,clinical neurology) in Journal Citation Report (JCR),and careful consulation of expert clinicians,we identified 50 journals.Their bibliographic records (including references) published in 2011 were downloaded,and the frequency of the references (citations) in each sub-specialty was counted and the highly cited records were extracted.We performed a clustering analysis according to the co-cited times among any pairs of the highly cited records.To tag each cluster of highly cited records,we browsed the titles and abstracts of all highly cited records in the same cluster,and concluded the main topics of each cluster.Finally,we extracted the current published papers devoted to particular cluster by some clustering analysis indicators.The clusters of highly cited records were considered as the intelligence base,and the main topics in current papers which citing these highly cited papers were considered as research fronts.Results Totally 50 journals on 10 sub-specialties in internal medicine were identified.A total of 202 highly cited papers,38 clusters (knowledge bases),and 152 corresponding current citing papers presenting the research fronts were selected.Conclusions We confirm and present research fronts in 10 major sub-specialties of internal medicine.This study provides a synchronic structure of contemporary research activities in internal medicine sub-specialties.

Objective To investigate the effect of polymorphism of TNF-?gene G308A on sever- ity of myocardial damage during cardiopulmonary bypass(CPB).Methods Sixty-three congenital ca- ses with ventrieualr septal defect(VSD)were divided into groups TNF1 and TNF2 after TNF-?gene pol- ymorphism was identified by polymerase chain reaction-restriction fragment length polymorphism(PCR- RFLP)before surgery.When the right atrium was opened and closed,specimens of myocardium were ob- tained to study the ultrastructural changes by electron microscope and determine expression of TNF-?mR- NA.Concentration of TNF-?in plasma was measured by radio-immunity after anesthetic induction(T1), 20 minutes of CPB(T2),at the end of CPB(T3) and six hours after CPB(T4)in all cases,respective- ly.Results (1)TNF-?level and the expression of TNF-?mRNA in myocardium were significantly increased during CPB(P＜0.05)in both groups.(2)TNF-?mRNA level of group TNF2 was significant- ly higher than that of group TNF1(P＜0.05).The myocardial CK-MB in group TNF2 was significantly higher than that in group TNF1 at 24 hours postoperatively(P＜0.01).The electron microscope showed more severe ultrastructural changes of myocardium in TNF2 group compared with that in group TNF1(P＜0.05).(3)The concentration of TNF-?in blood plasma in group TNF2 was significantly higher than that in group TNF1 at time points of T2-T4(P＜0.05).Conclusion Polymorphism of TNF-?gene G308A may influence the transcription and production of TNF-?in vivo and hence affect severity of myo- cardial damage.
