Objective To investigate the effects and the possible mechanism of insulin like growth factor-1 ( IGF1 ) on proliferation and migration of human umbilical vein endothelial cells ( HUVEC) in high glucose. Methods Cultured HUVEC were divided into 5 groups( control group, high glucose group, hypertonic group, high glucose+IGF 1 group, high glucose+IGF1+ AZD5363 group) . The proliferation was detected by methyl thiazolyl tetrazolium ( MTT) , the migration was detected by transwellchamber. The mRNA expressions of serine/threonine kinase( Akt) and FoxO1 were detected by real-time PCR. The protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were detec-ted by immunohistochemisty. Results Compared with the control group, the rate of cell survival in high glucose group decreased significantly(P<0. 05), the transitional was decreased significantly(P<0. 05), the mRNA ex-pression of FoxO1 was increased significantly( P<0. 05 ) , the protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were increased. Compared with high glucose group, the cell survival rate and migration rate in high glucose+IGF1 group were increased significantly, the mRNA expression of FoxO1 was decreased significantly(P<0. 05), the protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were decreased. Compared with high glucose group, the cell survival rate and migration rate in high glucose+IGF1+AZD5363 group had no significant difference, the mR-NA expression of FoxO1 was decreased significantly ( P<0. 05 ) , the protein expressions of FoxO1/p-FoxO1 had no significant difference. The mRNA expression of Akt in five groups had no significant difference. Conclusion IGF1 can improve the proliferation and migration of endothelial cell in high glucose. It shows that IGF1 acts through Akt to promote FoxO1 phosphorylation.

In the background of the crisis of doctor-patient relationship and the effectiveness of medical humanities education doubts we need to think about how to achieve,transform and reflect the value of doctors' understanding on their professional meaning,how to realize the functional significance of doctorpatient cooperation and how to make doctors put themselves in patients' place by the curriculum and its operating mechanism.This paper discussed the external environment and the microcosmic environment from the externality and connotation of the humanities curriculum.And the way to reflect and achieve the value transformation of the medical humanistic curriculum in the mechanism of education was considered.This paper put forward combining the institutional mechanism of policy leading,the subject mechanism that is the basis of the curriculum,the constitutive mechanism of curriculum system and the cultural mechanism to make students study and internalize,and made some suggestions.

BACKGROUND:Light-cured resin is a new kind of material with beautiful color, high strength, wide range of applications, easy-to-use and inexpensive features. Patients are wil ing to accept it because of less or no grinding of the teeth.
OBJECTIVE:To observe the effect of light-cured resin to fil the interdental space between maxil ary anterior teeth.
METHODS:A total of 32 patients aged 21-52 years were enrol ed, 107 teeth with 75 oversized maxil ary spaces, including 15 males and 17 females. One space between bilateral central incisors was found in 14 cases;three spaces between bilateral central incisors, left lateral incisor, and left canine were found in three cases;three spaces between bilateral central incisors, right lateral incisor, and right canine were found in two cases;four spaces between left central incisor, left lateral incisor, left canine, right central incisor, and right lateral incisor were found in three cases;three spaces between bilateral central incisors and lateral incisors were found in six cases;four spaces between left central incisor, left lateral incisor, right central incisor, right lateral incisor, and right canine were found in four cases. Al the oversized maxil ary spaces were fil ed with light-cured resin. Then, crown morphology, adaptation, color, degree of wear and loosening were observed during fol ow-up.
RESULTS AND CONCLUSION:After 3-year fol ow-up, 17 of 32 cases were successful in tooth repair:the crown morphology and tooth adaptation were good, and there was no prosthesis loosening or detachment and discoloration. The tooth space was repaired basical y in another nine cases:the crown morphology and tooth adaptation were not good enough, no prosthesis loosening or detachment was found, but there were some defects at the gingival margin and contact surface of teeth as wel as mild discoloration. Tooth repair failed in the other six cases with worse crown morphology and adaptation, prosthesis loosening or detachment, and severe discoloration, which need to be repaired again.

Purpose To explore the effect of speckle tracking imaging (STI) in early detection of coronary artery disease (CAD) in patients with hypertension (HT),and to intervene early to alleviate or delay the progression of CAD.This would provide theoretical evidence in controlling the development and improving the prognosis of CAD.Materials and Methods From January 2013 to April 2015,a total of 166 cases of hospitalized patients from the First Affiliated Hospital of Sun Yat-sen and Jiangmen Central Hospital were retrospectively analyzed,including HT group (n=42),CAD group (n=35),HT+CAD group (n=49) and control group (n=40).Conventional measurement and STI were used to analyze the conventional values and the 17 section peak strain value of the left ventricle.Results The total mean strain,average peak strain of lesion segment and minimum peak strain in CAD group and HT+CAD group were significantly lower (P＜0.05) compared to the control group.ROC analyses showed that the AUC for total mean strain,average peak strain of lesion segment and minimum peak strain value were 0.71,0.76,and 0.70,respectively.Using a combined cut-off of ≥-18％ of average peak strain of lesion segment,≥-19％ of total mean strain and ≥-6％ of minimum peak strain value,the performance of CHD diagnosis had a sensitivity of 91.3％ and a specificity of 83.5％.Conclusion Speckle tracking automatic function imaging can be used to quantitatively analyze abnormal left ventricular segmental wall movement.It improves the detection in hypertension patients with coronary artery disease.

Objective:To assess effect of fluvastatin on vascular endothelium-dependent diastolic function of hypercholesterolemia patients. Methods:Thirty five patients with hypercholesterolemia were treated with fluvastatin (40 mg/d,po) for 8 weeks. 25 healthy adults were as control group.The baseline of brachial angiobore and the changes of it at response to nitroglycerin and reactive hyperemia were measured by Dopple ultrasound before and after treatment in hypercholesterolemia patients. Blood lipids,blood concentrations of NO and NOS were also measured before and after treatment. Results:①In patients with primary hypercholesterolemia the vascular endothelium-dependent dilation function (EDD)was much reduced as compared with the control, so as for blood concentrations of NO and NOS. ② Serum total cholesterol,low density lipoprotein cholesterol and triglycerides were significantly lowered by 8-week treatment of fluvastatin(p

Objective To investigate the relationship between resting heart rate (RHR) and target organs damage (TOD) in senile metabolic syndrome(SMS). Methods With case-control study,215 elderly patients with MS were divided into 3 groups according to the level of RHR [RHR1 group: RHR <70 beats/ minute (bpm) (n=55);RHR2group: 70 bpm ≤RHR<80 bpm [n=87);RHR3 group: RHR≥80 bpm (n=73).Mean-while ,60 healthy senile persons were taken as normal control group. For all objects researched, electrocardiography, echocardiography,carotid ultrasonography, creatinine clearance rate (Ccr) and quantitative assay for 24 hours' urina-ry microalbuminuria (MAU) were performed. Part of SMS patients was examined by coronary angiography and com-puter tomography (CT) of head. Results ① Compared with normal control group, RHR groups showed higher lev-els of carotid intima-medial thickness (IMT), carotid arterial diameter (CAD), left ventricular mass index (LVMI) and MAU, lower levels of left ventricular ejection fraction (LVEF) and Ccr (P<0.05 or 0.01). With RHR increas-ing among RHR groups,IMT,CAD,LVMI,MAU and the score of coronary artery stenosis increased,and LVEF and Cer decreased (P<0.05 or 0.01). ② The levels of IMT, CAD, LVMI and MAU were positively correlated to RHR (r=0.34,0.25,0.62, and 0.57, respectively, P<0.05 or 0.01). However, the levels of LVEF and Ccr were nega-tively correlated to RHR (r=-0.60,-0.52 respectively,P<0.01). ③ Logistic multivariate analysis showed that RHR, pulse pressure (PP), systolic blood pressure (SBP) and diastolic blood pressure (DBP) influenced TOD,such as myocardial hypertrophy,coronary heart disease,heart failure, cerebral stroke and renal damage in dif-ferent degrees, among them, PP and RHR played more important roles than those of other factors. Conclusion RHR may be an independent risk factors of TOD in senile MS. It is indicated that RHR regulation is important for the de-velopment of senile MS.
