MicroRNA-375 (miR-375) is closely related to the development of cancer,such as liver cancer,gastric cancer,pancreatic cancer,endometrial cancer,esophageal cancer,non-small cell lung cancer,etc.The mainly tumor pathogenesis related miR-375 includes that miR-375 is combined with specific target genes,can degrade mRNA or inhibit protein translation in the transcriptional level,and plays antitumor effect of inhibition of cell proliferation,promoting cell apoptosis and inhibiting the invasion and metastasis.miR-375 is expected to be a new target for cancer therapy,which may become an important biomarker for the diagnosis,treatment and prognosis of cancer.

This article discussed the problem of assistive technology curriculum in higher vocational education school, and the reform in the future.

A new technique was developed to fabricate PDLLA and PDLLA/PELA composite scaffolds by thermally induced phase separation in combination, with particulate-leaching. Effects of PDLLA/PELA ratio, PEG/PLA ratio and PEG molecular weight on properties of mechanics, degradation behavior and cell toxicity as well as morphological properties were investigated. As the result showed, by thermally induced phase separation/ particulate-leaching, a unique morphology that macropores (100-250 microm) and micropores (5-40 microm)coexisted in the scaffold was obtained. An increase of PEG content or a decrease of PEG molecular weight raised the porosity of the scaffold. A decrease of PDLLA/PELA ratio or an increase of PEG/PLA ratio weakened mechanical properties and accelerated the degradation of the scaffold. PDLLA and PDLLA/PELA scaffolds didn't show cell toxicity. When PDLLA/PELA ratio was 3:1 and PEG5000/PLA ratio was 25:75, the scaffold got a regular, highly interconnected, macro-co-micro porous structure.

Pyridaben is a broad-spectrum acaricide widely used in agriculture, accidental or self-administration of large doses of pyridaben can cause multiple organ failure in patients. Due to its damage to multiple organs and no specific antidote, the mortality rate is high. This paper reports two patients who took a large amount of pyridaben, developed severe metabolic acidosis, hyperlactatemia, toxic encephalopathy, and liver, kidney, heart and digestive tract damage. After timely gastric lavage, catharsis, organ support andblood purification treatment, the condition improved and discharged. It is expected to provide clinical ideas for the treatment of pyridaben poisoning.
