Objective To investigate the effect of grape procyanidins (GPC) and the regulation of estrogen receptor(ER)on proliferation of human breast cancer(MCF-7)cells. Method MCF-7 cells were cultured with GPC,and divided into six groups: tumor control,high,middle and low dose GPC treated,estrogen antagonist ICI 182. 780 (ICI) control,ICI and GPC combined treated. The proliferation activity level of MCF-7 cells was determined by MTT assay,and the levels of the proliferating cell nuclear antigen (PCNA) and Bax protein were measured by immunohistochemistry method. Results Compared with tumor control group,the level of proliferation activity and the expression of PCNA were significantly decreased in high dose GPC group,while the expression of Bax protein was increased significantly. Compared with high dose GPC group,both the proliferation activity and the PCNA expression were increased,and Bax protein expression decreased significantly in ICI and GPC combined treated group. Conclusion GPC can inhibit the proliferation and induce the apoptosis of human breast cancer cells effectively,and its mechanism is closely related to the regulation of ER.

Short course chemotherapy combined with local field radiotherapy (IFRT) is an important treatment for limited-stage (Ⅰ -Ⅱ)diffuse large B cell lymphoma patients,but the value of radiotherapy has been disputed.Some patients may be cured by combined chemotherapy which contains anthracycline,but there are some patients still facing death.Therefore,researchers try to improve survival of patients further by increasing the density or intensity of the chemotherapy dose,but attempt to reduce the dose or the use of low toxicity drugs for elderly patients.In addition,researches such as radioimmunotherapy and biological targeted therapy have made certain progress.

Peroxisome proliferator-activated receptors (PPARs) are a family of nuclear hormone receptors belonging to the steroid receptor superfamily. Three PPAR isoforms, PPAR?, PPAR? (also known as PPAR?) and PPAR? have been found in the mouse. They can activate expression of many genes, including those involved in lipidmetabolism. PPAR? is ubiquitously expressed, but the level of expression differs markedly between different cell types. PPAR? is expressed in skeletal muscle at 10- and 50-fold higher levels compared with PPAR? and PPAR?, respectively. A role for PPAR? in skeletal muscle is to increase the genes expression with relation to oxidative metabolism. In order to determine the molecular mechanisms governing PPAR? gene expression in muscle, a 2 kb 5′ flanking region was cloned and analyzed. The DNA fragment is able to transcribe GFP in COS7 cells. Dual luciferase assay is used to quantify promoter activity. Deletion analysis of the 2 kb PPAR? promoter fragment in COS7 and NIH 3T3 cells shows that the proximal promoter sequence, nt -197 to +120, confers basal transcriptional activity of the mouse PPAR? gene. Computational analysis of putative cis-acting elements located within the ～2.0 kb mouse PPAR? 5′-flanking sequence was performed using the TRANSFAC database and MatInspector software and 4 potential MEF2A binding sites were found. And there is a potential binding site sharing 100% identity with positive element of MEF2A in the proximal promoter (nt -261). Co-transfection experiments of the PPAR? promoter reporter and pMEF2A expression plasmid (pMEF2A) showed that MEF2A significantly enhanced transcription activity of PPAR? promoter in NIH 3T3. Moreover, the enhancive effect depended on the concentration of plasmid pMEF2A transfected into cells. The results suggested that MEF2A may enhance transcription activity of the PPAR promoter in muscle cells.

Objective To observe the correlation of estrogen,fasting insulin(FINS),fasting plasma glucose (FPG),glycosylated hemoglobin(HbA1c),blood lipids and carotid arteries -membrane thickening(IMT)in the postmenopausal women with type 2 diabetes.Methods 63 postmenopausal women with type 2 diabetes were divided into normal IMT group(group A),IMT thickening group(group B),plaque group(group C)according to the vascular ultrasound carotid artery intima thickness,at the same time 15 cases of healthy physical examination as control group (group D).All of the groups were detected the plasma total cholesterol(TC),high-density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C),fasting insulin(FINS),fasting plasma glucose(FPG),gly-cosylated hemoglobin(HbA1c),follicle-stimulating hormone(FSH),estradiol(E2).Results Compared with group A,the levels of FINS,IR,HbA1c,TC,LDL-C in group C was higher(t=16.83,14.44,2.50,2.38,2.42,all P<0.01 or P<0.05),however,the results of E2,HDL-C was decreased(t=7.32,5.51,all P<0.01).The levels of FINS,HbA1c,TC,LDL-C,FSH,IR in group D was lower than those of group C(t=19.74,36.44,8.64,7.95, 27.13,6.71,all P<0.01),On the contrast,the levels of HDL-C,E2 were elevated(t=11.34,8.72,all P<0.01). The Pearson's correlation analysis showed that E2 had negative correlation with FINS,IR,TC,LDL-C (P<0.01 or P<0.05).E2 had positive correlation with HDL-C(P<0.05).Logistic regression analysis showed that IMT and FINS,IR,HbA1c,LDL-C were positively correlated(OR=2.94,72.63,27.30,98.18,all P<0.01),while nega-tively correlated with E2 levels(OR=2.94,P<0.01).Conclusion The increased level of estrogen was a protective factor of carotid artery atherosclerosis in postmenopausal women with type 2 diabetes.

BACKGROUND:Tissue-engineered biomaterials have the similar structure and function with autologous tissues. OBJECTIVE:To explore the osteoinduction of the bone biomaterial composited with rat bone marrow mesenchymal stem cel s in the treatment of large costal defects. METHODS:Forty Wistar rats were enrol ed used for the preparation of right large costal defect models, and then randomized into two groups, fol owed by the implantation of calcium chloride-sodium alginate gel (control group) or chloride-sodium alginate-bone marrow mesenchymal stem cel s (experimental group). At 2, 4 and 8 weeks after implantation, chest X-ray radiograph and histological examination of the defect region were conducted. RESULTS AND CONCLUSION:X-ray showed that in the experimental group, the defect area had no significant changes at the 2nd week after implantation until the formation of few bones at the 4th week;and at the 8th week, both ends of the defect region gradual y connected, and newly formed bones were ful of the defect. In contrast, the defect region in the control group showed no obvious bone healing, and both ends of the defect closed and osteosclerosis occurred. In the experimental group, there were a smal amount of fibrous tissues and numerous inflammatory cel s infiltratied in the material compartment, and no connection occured between the material and broken ends;there were numerous inflammatory cel s but no bone tissues in the control group at the 2nd week. At the 4th week, the scaffold degraded gradual y and abundant bone tissues were seen in the experimental group;the scaffold degraded little, and bone tissues aggregatied at the both defect ends in the control group. Up to the 8th week, the two kinds of scaffolds degraded mostly. A large number of bone tissues and trabeculae formed and the both defect ends were connected with the newly formed bones in the experimental groups, while in the control group, osteosclerosis appeared at both ends of the defect. To conclude, the bone biomaterial composited with rat bone marrow mesenchymal stem cel s promotes the repair of large costal defects.

Objective To analyze the clinical features and risk factors of migraine patients with white matter le-sions (WMLs). Methods One hundred ten clinically diagnosed migraine patients who underwent magnetic resonance im-aging (MRI) scans from October, 2010 to August, 2013 were enrolled in Shandong Provincial Hospital. One hundred ten migraine patients were divided into two groups:WMLs group and non-WMLs group based on the presence or absence of WMLs in MRI scans. The clinical features of the patients and location and number of WMLs were investigated. Noncondi-tional multivariate stepwise logistic regression after univariate analysis was used to analyze the data. Odds ratio (0R) and 95 confidence interval after adjustment for possible confounding variables were calculated. Results①There were 36 patients with WMLs among the 110 migraine patients. The incidence of WMLs in migraine patients was 32.7%. The WMLs in migraine patients were predominantly present in the frontal and parietal lobes (59.1%). ② Compared with non-WMLs group, there were significant increases in disease duration (5.3±3.7 vs. 7.6±4.9, P﹤0.01), frequency of head-ache attack (3.5 ± 2.3 vs. 4.6 ± 2.2, P﹤0.05), aura (18.9%vs. 36.1%, P﹤0.05) and family history of migraine (12.2%vs. 44.4%, P﹤0.01) in WMLs group.③The independent risk factors of WMLs in migraine patients were family history of mi-graine (OR=5.995), aura (OR=3.067) and long disease duration (OR=1.165). Conclusions Family history of migraine, au-ra and disease duration are the predictive risk factors of WMLs in migraineurs.
