Height development of 25 225 children aged 6 to 15 years in Nanning City / 中国儿童保健杂志

【Objective】 To analyze the height growth of children aged 6 - 15 years in Nanning, Guangxi Zhuang Autonomous Region, so as to provide evidence for the assessment of local children′s height development. 【Methods】 A total of 25 225 children aged 6 - 15 years were selected to get their physical examination data from 41 primary schools in Nanning by stratified cluster sampling method in December 2021.Then the height data were compared with the current domestic standards. 【Results】 The average height of boys in Nanning was lower than the national standard before the age of 10 years and 7 months, and the gap with the national standard gradually narrowed after the age of 10 years and 7 months. The average height of boys in Nanning City exceeded the national standard between the age of 11 years and 1 month and 13 years and 6 months, and then lagged behind the national standard again after the age of 13 years and 7 months. The mean height of girls in Nanning City was lower than the national standard height in several age groups, and it was more obvious before the age of 9 years and 7 months. The proportion of height ≤-2s,≤-s,≥ +s and ≥+2s in boys aged 6 to 15 years in Nanning City fluctuated from 2.59% to 6.04%, 12.09% to 23.43%, 7.18% to 18.79% and 0.93% to 3.14%, respectively; the total proportions were 4.56%, 17.46%, 11.35% and 1.74%, respectively; the minimum/maximum proportion values of each height group were at 11 years old /8 years old, 14 years old/8 years old, 8 years old/12 years old, and 6 years old/11 years old, respectively. The proportions of girls aged 6 - 15 years in Nanning City with height ≤-2s, ≤-s, ≥+s, and ≥+2s fluctuated from 2.06% to 5.19%, 9.35% to 25.15%, 8.21% to 15.80% and 1.23% to 3.49%, respectively; the total proportions were 3.38%, 16.91%, 11.97% and 2.29%, respectively; and the minimum/maximum proportion values of each height group were at 13 years old/6 years old, 12 years old/6 years old, 7 years old/12 years old, and 6 years old/11 years old, respectively. 【Conclusions】 The overall height level of children in Nanning is still lower than the national level, with short prepubertal basal heights, an earlier age of onset of accelerated pubertal height, and a shorter duration of accelerated pubertal height in boys. Strengthening pre-pubertal height management and emphasizing the onset and duration of children′s pubertal development, especially the height development of boys during puberty, can help improve the adult lifelong height of children in this region.

The Circadian System Is Essential for the Crosstalk of VEGF-Notch-mediated Endothelial Angiogenesis in Ischemic Stroke / 神经科学通报·英文版

Ischemic stroke is a major public health problem worldwide. Although the circadian clock is involved in the process of ischemic stroke, the exact mechanism of the circadian clock in regulating angiogenesis after cerebral infarction remains unclear. In the present study, we determined that environmental circadian disruption (ECD) increased the stroke severity and impaired angiogenesis in the rat middle cerebral artery occlusion model, by measuring the infarct volume, neurological tests, and angiogenesis-related protein. We further report that Bmal1 plays an irreplaceable role in angiogenesis. Overexpression of Bmal1 promoted tube-forming, migration, and wound healing, and upregulated the vascular endothelial growth factor (VEGF) and Notch pathway protein levels. This promoting effect was reversed by the Notch pathway inhibitor DAPT, according to the results of angiogenesis capacity and VEGF pathway protein level. In conclusion, our study reveals the intervention of ECD in angiogenesis in ischemic stroke and further identifies the exact mechanism by which Bmal1 regulates angiogenesis through the VEGF-Notch1 pathway.

Different doses of human umbilical cord mesenchymal stem cells improve learning and memory ability of dementia rats / 中国组织工程研究

BACKGROUND:To delay the onset of Alzheimer’s disease, transplantation of viable and wel-differentiated stem cel s is expected to repair neural tissue, which has been an issue of concern. OBJECTIVE:To explore the effects of different doses of human umbilical cord mesenchymal stem cel s (hUCMSCs) on learning and memory ability of Alzheimer’s disease rats. METHODS:Fifty Sprague-Dawley rats, 7 months of age, were randomized into normal, model, high-, middle-and low-dose hUCMSCs groups (n=10 per group). Rats in model and UCMSCs groups were used to make Alzheimer’s disease animals through intraperitoneal injection of 150 mg/kg D-galactose for 90 days, and rats in the normal group were given intraperitoneal injection of normal saline for 90 days. In the three hUCMSCs group, passage 3 hUCMSCs at doses of 1×105/0.2 mL/20 g, 5×105/0.2 mL/20 g, and 1×106/0.2 mL/20 g were injected via the tail vein, respectively. Forty-five days after cel transplantation, Morris water maze test was used to detect rat’s learning and memory abilities, and hematoxylin-eosin staining was used to observe pathological changes of the rat hippocampal CA1 region. RESULTS AND CONCLUSION:Compared with the normal group, the rats in the model group showed significant reduction in the ability of learning and memory. Compared with the model group, the escape latency was significantly shortened in the middle-dose hUCMSCs group (P<0.05), while the number of passing times through the platform was increased significantly (P<0.05). In the model group, the cel s in the hippocampal CA1 region were arranged irregularly with unclear nucleoli and a part of cel s were concentrated and deeply stained. In the middle-dose hUCMSCs group, the cel s in the hippocampal CA1 region were arranged regularly with clear nucleoli, and only individual cel s were stained deeply. These findings indicate that middle-dose hUCMSCs transplantation can improve the learning and memory abilities of Alzheimer’s rats.
