Old Is Gold

Beijing Review 2018年第45期61卷 44-45页

作者： zhao piao

D uring autumn nights, it＇s common to see strollers walking appreciatively on the town wa in Zhengding an ancient county in north China＇s Hebei Province. The wall is one of the few remaining segments of the ancient fortification built during the Ming Dynasty （1368-1644） and preserved to the present day. Standing on it, visitors can see four old pagodas lined up from south to north, forming a spectacular sight. The wall and other ancient monuments have brought new opportunities for the local tourism industry amid the Central Government＇s initiative to develop all-region tourism, in which an entire region is developed as a tourist destination.

New Roots, New Life

Beijing Review 2018年第33期61卷 30-31页

作者： zhao piao Clothing dealers moving out of Beijing find a new home in Cangzhou

After graduating from university in 2011, Zang Yadan, from east China＇s Zhejiang ,Province, and her husband started a clothing business in Beijing. When informed about the relocation of wholesale markets out of the capital, they decided to stay in north China in a bid to maintain the base of their business. Hence, they conducted field trips to Tianjin and Yongqing , north China＇s Hebei Province, but in the end, they settled on Cangzhou, Hebei.

Objective To estimate the relative risks of dyslipidemia, hypertension, diabetes mellitus, and metabolic syndromes among overweight and obese Chinese children compared with their normal weight counterparts. Methods Overweight and obesity were defined by age- and sex-specific BMI classification reference for Chinese children and adolescents. Pediatric metabolic syndrome （MetS） and each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia for adults was applied as well. General linear model factor analysis and chi-square test were used to compare the difference in metabolic indicators among normal weight, overweight, and obese groups. Multiple logistic regression analysis was performed to estimate the odds ratio of metabolic abnormalities between obesity, overweight, and normal weight children, after adjustment for living area, family economic level, age, sex, and daily exercise time and TV watching time, as well as different dietary indices in the model. Results Significant increases in blood lipids, glucose, and blood pressure were found among overweight and obese children as compared with their counterparts with normal weight. By applying WGOC-recommended BMI classification, the risks for hypertriglyceridemia, low HDL and dyslipidemia among overweight children were 1.9, 1.4, and 1.5 times, and was 3.3, 1.5, and 1.8 times among obese groups compared to their counterparts with normal weight after adjustment for age, sex, region, socioeconomic status, physical activity, and dietary intakes. The overweight and obese children （15-17.9 years） had a high-risk of developing hypertension, which was 2.3 and 2.9 times higher than their counterparts with normal weight. Above 90% obese adolescents had abdominal obesity, while less than 1% normal weight ones had abdominal obesity. No obese adolescents were free from any risk factors for MetS, while 36.9% of normal weight adolescents were from the risk factors. 83.

BMP9 mediated osteogenic differentiation mechanisms of MSCs were widely explored, however, mechanisms of BMP9-induced angiogenesis still need to be clarified. We previously characterized that Notch1 promoted BMP9-induced osteogenesis–angiogenesis coupling process in mesenchymal stem cells (MSCs). Here, we explored the underlying mechanisms of lncRNA H19 (H19) mediated regulation of BMP9-induced angiogenesis through activating Notch1 signaling. We demonstrated that basal expression level of H19 was high in MSCs, and silencing H19 attenuates BMP9-induced osteogenesis and angiogenesis of MSCs both in vitro and in vivo. Meanwhile, we identified that BMP9-induced production of CD31+ cells was indispensable for BMP9-induced bone formation, and silencing H19 dramatically blocked BMP9-induced production of CD31^(+) cells. In addition, we found that down-regulation of H19 inhibited BMP9 mediated blood vessel formation and followed subsequent bone formation in vivo. Mechanistically, we clarified that H19 promoted p53 phosphorylation by direct interacting and phosphorylating binding, and phosphorylated p53 potentiated Notch1 expression and activation of Notch1 targeting genes by binding on the promoter area of Notch1 gene. These findings suggested that H19 regulated BMP9-induced angiogenesis of MSCs by promoting the p53-Notch1 angiogenic signaling axis.

Specialized therapeutic delivery, or use of pharmaceuticals and other biomaterials to target specific parts of the body or diseased tissue, has long been sought as an ideal way of treating human diseases. A recent article published in Nature Biomedical Engineering revealed an innovative strategy to engineer nucleus-free human mesenchymal stem cells (MSCs) for targeted delivery of therapeutics to disease site.1 MSCs have emerged as promising vehicles of therapeutic delivery.2,3 MSCs are undifferentiated pluripotent stem cells derived from areas such as bone marrow and adipose tissue.4,5 MSCs are sought after for their chemotaxis, or ability to home towards a chemical stimulus, and capacity for modification with elements such as chemoattractant receptors and adhesion molecules.1 These properties allow for site-specific and minimally-invasive therapeutic administration and treatment.
