Self-propelled nanomotor reconstructs tumor microenvironment through synergistic hypoxia alleviation and glycolysis inhibition for promoted anti-metastasis

Solid tumors always exhibit local hypoxia, resulting in the high metastasis and inertness to chemotherapy. Reconstruction of hypoxic tumor microenvironment (TME) is considered a potential therapy compared to directly killing tumor cells. However, the insufficient oxygen delivery to deep tumor and the confronting "Warburg effect" compromise the efficacy of hypoxia alleviation. Herein, we construct a cascade enzyme-powered nanomotor (NM-si), which can simultaneously provide sufficient oxygen in deep tumor and inhibit the aerobic glycolysis to potentiate anti-metastasis in chemotherapy. Catalase (Cat) and glucose oxidase (GOx) are co-adsorbed on our previously reported CAuNCs@HA to form self-propelled nanomotor (NM), with hexokinase-2 (HK-2) siRNA further condensed (NM-si). The persistent production of oxygen bubbles from the cascade enzymatic reaction propels NM-si to move forward autonomously and in a controllable direction along H

Effect of Thunder-Fire moxibustion on night-urine symptoms of benign prostatic hyperplasia / 现代临床护理

Objective To investigate the effect of Thunder-fire Moxibustion on nocturnal urinary symptoms in patients with benign prostatic hyperplasia (BPH). Methods According to hospitalized number from January to December 2018, 61 BPH patients with frequent nocturnal urination were divided into control group (treated with routine nursing and drug therapy) and observation group, where the Thunder-fire moxibustion was used once a day for one course of treatment every 10 days for 3 courses of treatment. The effect was observed by looking into the number of nocturnal urine and the prostate symptoms. Result After the treatment, the number of nocturnal urine in the observation group was smaller than that in the control group, and the IPSS score in the observation group was lower than that in the control group (P ＜0.001), and no adverse reactions were observed. Conclusion The Thunder-fire Moxibustion combined with drug therapy can improve nocturnal urinary symptoms of benign prostatic hyperplasia in a safe way.

Advances research in chromatin DNaseⅠhypersensitive sites and its transcriptional regulation function / 医学研究生学报

DNaseⅠhypersensitive sites (DHSs) are regions of extreme chromatin which is highly sensitive to DNaseⅠ.Ge-nome-wide mapping DHSs is a powerful method for identifying many different types of regulatory elements within nuclear chromatin .It can help systematically resolve gene and genomic information , and the dynamic molecular mechanism of transcriptional regulation .This paper reviews the distribution of DHSs , the technology of DNase-seq and the research progress in transcriptional regulation functions of DHSs.
