The color depth is related to the component concentration, and the darker the color, the greater the measured component concentration, and vice versa. In this paper, four color discrimination methods in urinary dry chemical analysis were introduced, i.e. the method based on integrating sphere photoelectric conversion, the method based on charge-coupled device (CCD) image sensor, the method based on color sensor, and the method based on the combination of color sensor and fiber bundle.

Skin wound is one of the most common surgical diseases. The process of wound healing can be summarized as three stages: inflammation stage, fibrous tissue proliferation stage, and scar formation and repair stage. Incomplete repair of the wound leads to skin scarring, which causes the tissue to lose its normal structure and function, and seriously affects the aesthetic appearance. Traditional treatment methods can not restore the normal function of the skin and have obvious adverse reactions, which can not meet people's needs. Stem cell therapy, especially adipose derived stem cells (ADSCs) plays a essential rule in the process of wound healing making it a research hotspot in recent years. ADSCs can secrete a variety of growth factors during wound healing to reduce wound inflammatory response, promote wound regeneration epithelialization and vascular reconstruction, thereby promoting wound healing. In this paper, the wound healing process and its regulation mechanism were summarized, and the role of ADSCs in wound healing at home and abroad and its clinical application progress were reviewed. \u0000 \u0000 \u0000Key words: \u0000Adipose derived stem cells; Skin; Wound healing","PeriodicalId":61751,"journal":{"name":"国际生物医学工程杂志","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47228961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 100 rats successfully modeled were randomly divided into the diabetes group, astragalus polysaccharide treatment group, hUSCs treatment group, and astragalus polysaccharide + hUSCs treatment group, with 25 rats in each group. After 2 weeks of treatment, the FBG concentration, insulin and C-peptide concentrations, and body weight changes were measured in each group. The distribution and survival of PKH-26-labeled hUSCs in rat pancreatic tissue were observed by fluorescence microscopy. TUNEL method was used to detect the apoptosis of rat islet cells.

MTT assay was used to detect the proliferation of HCT116 and CT26 cells by PFTP-E, OA and PTX in vitro. Apoptosis was observed by Hoechst 33258 staining. Flow cytometry was used to detect apoptosis, cell cycle, mitochondrial membrane potential and intracellular ROS. Western Blot were used to detect the expressions of apoptosis-related proteins B cell lymphoma-2 (Bcl-2), BCL2 associated X protein (Bax), poly(adenosine diphosphate-ribose) polymerase (PARP), Caspase-3, Caspase-9, cell cycle related proteinB1 (Cyclin B1), endoplasmic reticulum stress-related proteins glucose-regulated protein 78 (GRP78), protein kinase R-like ER kinase (PERK), eukaryotic initiation factor 2α (eIF2α), C/EBP-homologous protein (CHOP), and autophagy microtubule associated protein light chain 3A/B (LC3A/B). \u0000 \u0000 \u0000Results \u0000PFTP-E is mainly composed of steroids and triterpenoids. PFTP-E, OA and PTX can inhibit the proliferation of HCT116 and CT26 cells in a time- and dose-dependent manner, induce apoptosis, and block the cell cycle at G0/G1 and G2/M phases. PFTP-E can collapse mitochondrial membrane potential of HCT116 and CT26 cells and increase the content of intracellular reactive oxygen species, which is similar to the effect of PTX. PFTP-E and PTX can up-regulate CytC, Bax, GRP78, p-PERK, p-eIF2α and CHOP, down-regulate Bcl-2, significantly increase the content of cleaved PARP, Caspase3 and Caspase9, and induce endoplasmic reticulum stress response.
