VE-statin/Egfl7 expression in malignant glioma and its relevant molecular network

This study investigated VE-statin/Egfl7 expression and its role and regulatory mechanism in malignant glioma progression. Forty-five paraffin-embedded glioma (grade I-II: n=24; grade III-IV: n=21) were examined. VE-statin/Egfl7 protein expression was detected via immunohistochemistry, and its correlation with pathological grade was evaluated. Three-dimensional cell culture was then performed to investigate the influence of VE-statin/Egfl7 on the angiogenesis of umbilical vein endothelial cells. Microarray detection was used to molecularly profile VE-statin/Egfl7 and relevant signaling pathways in malignant glioma (U251 cells). Data showed that VE-statin/Egfl7 protein was mainly expressed in the cytoplasm of cancer and vascular endothelial cells and was significantly related to the degree of malignancy (t=4.399, P<0.01). Additionally, VE-statin/Egfl7 expression was low in certain gray-matter neurons but undetectable in glial cells. VE-statin/Egfl7 gene silencing significantly inhibited angiogenesis in umbilical vein endothelial cells. The following microarray results were observed in VE-statin/Egfl7-silenced U251 cells: 1) EGFR family members showed the highest differential expression, accounting for 5.54% of differentially expressed genes; 2) cell survival-related signaling pathways changed significantly; and 3) the integrin ανβ3 signaling pathway was markedly altered. Thus, malignant glioma cells and glioma vascular endothelial cells highly express VE-statin/Egfl7, which is significantly correlated with the degree of malignancy. Moreover, VE-statin/Egfl7 plays an important role in glioma angiogenesis. Microarray results indicate that VE-statin/Egfl7 may regulate EGFR and integrins to influence the FAK activity of downstream factors, triggering the PI3K/Akt and Ras/MAPK cascades and subsequent malignant glioma development.     

Clinical significance of HPV DNA cotesting in Korean women with ASCUS or ASC‐H

The purpose of this study was to evaluate the clinical significance of Human papillomavirus (HPV) DNA cotesting in Korean women with abnormal Papanicolaou (Pap) smear results based on colposcopic pathology. A total of 1012 women underwent liquid‐based Pap smears and hybrid capture II HPV DNA tests followed by colposcopy at the Korea University Hospital from January 2007 to May 2012. Of these women, 832 women were included in this retrospective study. The mean patient age was 45.4 ± 13.7 years (range:15–80). The distribution of Pap smear results was normal (4.7%), atypical squamous cells of uncertain significance (ASCUS) (42.1%), low‐grade squamous intraepithelial lesion (26.8%), ASC‐H (7.0%), and high‐grade squamous intraepithelial lesion (HSIL) (19.5%). In women with ASCUS, none of the 87 HPV‐negative had ≥cervical intraepithelial neoplasia (CIN2) (P < 0.001). In women with ASC‐H, only one out of 17 HPV‐negative vs. 14 out of 41 HPV‐positive had ≥CIN2 (P = 0.025). In patients with HSIL, 54.5% of HPV‐negative had ≥CIN2, as compared to 80.8% of HPV‐positive with ≥CIN2 (P = 0.039). Patients were further analyzed by age groups: <30 and ≥30 years. In HPV‐negative women, there was a significant difference in the ratio of ≥CIN2 (30.8% <30 vs. 4.5% ≥30, P = 0.005). When the HPV DNA test was negative in women ≥30, the risk of ≥CIN2 was significantly lower (P < 0.001). HPV DNA cotesting in women with ASCUS and ASC‐H furnish healthcare providers with informative data. There is a lower proportion of ≥CIN2 in HPV‐negative women and a higher proportion of ≥CIN2 in HPV‐positive. When HPV data were further evaluated by age group, the risk of ≥CIN2 was lower in HPV‐negative women, especially in women ≥30. Diagn.

急性心肌梗死冠脉侧支血流分数与Rentrop分级的相关性

目的 测定急性心肌梗死患者压力源性冠脉侧支血流分数（PDCF）,评价PDCF与传统的Rentrop分级间的相关性。方法 29例急性心肌梗死患者行介入术,术中应用冠脉内压力导丝根据Pw/Pa计算PDCF,以0．24为PDCF截值将29例分为2组：A组（19例）PDCF〉0．24,B组（10例）PDCF≤0．24。术后根据冠脉造影行Rentrop分级。使用统计学方法对数据进行线性回归分析,讨论PDCF与Rentrop分级间的相关性。结果 Rentrop分级同PDCF呈正相关（γ=0．75,P〈0．01）,但Rentrop≤1级的PDCF分布范围较为离散。结论 冠脉内压力源性PDCF测量可对AMI时侧支循环血流作出定量评价。     

青岛市示范幼儿园膳食营养状况分析

目的了解青岛市示范幼儿园膳食营养状况。方法膳食调查采取称重法。结果青岛市示范幼儿园热能、锌、钙、视黄醇等营养素1999年低于标准供给量,2005年达到标准供给量。2005年与1999年相比,钙、视黄醇的幼儿园达标率从1999年8.7%和30.4%提高到2005年57.1%和71.4%。但脂肪产热占总热能比例过高、钙磷比例不适宜等问题没有明显改善。结论幼儿园膳食中应多增加含钙丰富的食物,同时控制总热能,减少脂肪摄入。

Efficacy of acne vulgaris treatment protocols according to its clinical forms

To compare results of different treatment regimens based on stratification of acne to prescribe the right treatment protocol according to clinical form and grade of acne. A transversal, cohort study conducted in 230 patients with acne vulgaris. Patients were divided into three groups according to acne severity and the results of each protocol determined in 0, 4, 6, 8, 12, 18 and 24 weeks. Statistical analysis was conducted using Wilcoxon and Mann‐Whitney tests 230 patients (99 females and 131 males) took part in the study. In first grade acne (70 patients), the most effective drug for papulo‐pustular lesions was azelaic acid, where the average value of the reduction was 1.03% per week. For comedone reduction, the most effective drug resulted retinol with 17.7% mean reduction per week. In second grade acne (66 patients), the most effective scheme was: doxycycline + topical retinoid + benzoyl peroxide. In the third grade (92 patients), the most effective drug was oral isotretinoin. Accurate stratification, based on clinical characteristics is required for better outcome. Treatment success is related to the respective individually tailored treatment schemes in patients with acne.
