ABSTRACT
Objective:To explore application value of dance movement therapy in the chemotherapy of young and middle-aged patients with breast cancer, so as to provide reference for rehabilitation nursing.Methods:By convenient sampling method, 90 young and middle-aged female breast cancer patients during chemotherapy from June 2020 to June 2021 in Renmin Hospital of Wuhan University were enrolled in the present study. They were assiged to experimental group and control group with 45 cases in each group according to the enrolled ward. The control group received routine nursing and the experimental group received 4 cycles of dance movement therapy. Before and after intervention, the effects were assessed by Cancer Fatigue Scale (CFS) and Patient-Generated Subjective Global Assessment (PG-SGA) as well as biochemical nutrition indexes.Results:After intervention, the physical fatigue score, emotional fatigue score, cognitive fatigue score and total CFS score were (8.29 ± 3.58), (7.74 ± 1.68), (5.57 ± 1.11), (21.59 ± 4.41) points in the experimental group, which were significantly lower than (9.86 ± 3.49), (8.95 ± 2.62), (6.27 ± 1.70), (25.09 ± 4.33) points in the control group ( t values were 2.07-3.71, all P<0.05). After intervention, the PG-SGA score was (2.81 ± 0.71) points in the experimental group, which was significantly lower than (3.29 ± 1.15) points in the control group ( t=2.37, P<0.05). Conclusions:Dance movement therapy can alleviate the cancer related fatigue and promote nutritional status of young and middle-aged female breast cancer patients with chemotherapy.
ABSTRACT
Unlike healthy, non-transformed cells, the proteostasis network of cancer cells is taxed to produce proteins involved in tumor development. Cancer cells have a higher dependency on molecular chaperones to maintain proteostasis. The chaperonin T-complex protein ring complex (TRiC) contains eight paralogous subunits (CCT1-8), and assists the folding of as many as 10% of cytosolic proteome. TRiC is essential for the progression of some cancers, but the roles of TRiC subunits in osteosarcoma remain to be explored. Here, we show that CCT4/TRiC is significantly correlated in human osteosarcoma, and plays a critical role in osteosarcoma cell survival. We identify a compound anticarin-β that can specifically bind to and inhibit CCT4. Anticarin-β shows higher selectivity in cancer cells than in normal cells. Mechanistically, anticarin-β potently impedes CCT4-mediated STAT3 maturation. Anticarin-β displays remarkable antitumor efficacy in orthotopic and patient-derived xenograft models of osteosarcoma. Collectively, our data uncover a key role of CCT4 in osteosarcoma, and propose a promising treatment strategy for osteosarcoma by disrupting CCT4 and proteostasis.
ABSTRACT
Objective:To study the biocompatibility of fibrin sealant (FS) and human corneal fibroblasts (HCFs) obtained by small incision lenticule extraction (SMILE).Methods:The human corneal stromal tissues were selected from corneal stromal lens in 24 eyes of 12 patients underwent SMILE in the First Affiliated Hospital of Guangxi Medical University from March to April 2018.HCFs were isolated and cultured in vitro within 1 hour after the corneal stromal lens were extracted and the growth status of HCFs on FS surface was observed.HCFs were divided into 2-fold leaching solution group and normal control group, and the cells in the two groups were treated with 2-fold leaching solution or complete medium according to grouping, respectively.The apoptosis of HCFs in the two groups was observed by acridine orange (AO)/ethidium bromide (EB) double staining.The proliferation of HCFs in the two groups was assayed by methyl thiazolyl tetrazolium (MTT) method.HCFs in logarithmic phase were divided into 2-fold leaching solution group, normal control group, and the cells were treated with 2-fold leaching solution or complete medium according to grouping, respectively.In addition, a blank control group without HCFs was also set and treated with complete medium.The absorbance value and relative growth rate of HCFs in the three groups were compared.HCFs in logarithmic phase were divided into 1-fold leaching solution group, 2-fold leaching solution group and normal control group, and the cells were treated with 1-fold leaching solution, 2-fold leaching solution or complete medium culture according to grouping, respectively.The apoptosis of HCFs in the three groups was compared by Annexin V-FITC/PI flow cytometry, and the cytotoxicity of the three groups was graded.Written informed consent was obtained from each patient before the operation.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the First Affiliated Hospital of Guangxi Medical University (No.2018[022]). Results:HCFs grew well on FS surface and the morphology was normal.MTT assay showed that HCFs in the 2-fold leaching solution group and the normal control group had a similar proliferation tendency, and the toxicity index of HCFs in the 2-fold leaching solution group was graded 0-1 at 0-72 hours after changing solution.After AO/EB staining, the HCFs in the 2-fold leaching solution group and the normal control group were normal, and only a small amount of early apoptotic cells were observed.Flow cytometry showed that the apoptosis rates of the normal control group, once leaching solution group and the double leaching solution group were (4.96±1.09)%, (3.66±1.35)% and (2.88±0.66)%, respectively, with no significant difference among them ( F=2.89, P=0.13). Conclusions:FS has no cytotoxicity and has good biocompatibility with HCFs in vitro.
ABSTRACT
The research on human hepatobiliary development and disorders has been constrained by minimal access to human fetal tissue, and low accuracy of animal models. To overcome this problem, we have established a system for the differentiation of human pluripotent stem cells (hPSCs) into functional hepatobiliary organoids (HBOs). We have previously reported that our 45-d approach closely mimics key stages of hepatobiliary development, starting with the differentiation of hiPSC into endoderm and a small part of mesoderm, and subsequently into hepatoblast-like cells, followed by the parallel generation of hepatocyte-like cells and cholangiocyte-like cells, formation of immature HBO expressing early hepatic and biliary markers, and mature HBO displaying hepatobiliary functionality. In this study, we present an updated version of our previous protocol, which only needs 35 days to achieve maturation in vitro. Furthermore, a hepatobiliary culture medium is developed to functionally maintain the HBOs for more than 1.5 months. The capacity of this approach for producing large amounts of functional HBOs and enabling long-term culture in vitro holds promise for applications on developmental research, disease modeling, as well as screening of therapeutic agents.
ABSTRACT
[Objective] To investigate the effect of salvianolate injection on the levels of Serum interleukin-1β(IL-1β)and interleukin-18(IL-18) in acute exacerbated chronic obstructive pulmonary disease(AECOPD) patients. [Methods] Fifty-eight patients with acute exacerbated COPD from Respiratory Dep. of thrid Hospital Affiliated to Zhejiang Chinese Medical University, were randomly assigned to the treatment group(28 cases) and the control group(30 cases). Routine therapies for COPD were given to patients in the control group, while 20mg salvianolate injection was given to those in the treatment group by intravenous dripping, once daily for total 10 days. The levels of IL-18, IL-1β and blood gas analysis were evaluated before and 10 days after therapy. The levels of the cytokins were compared with 30 normal controls. [Result] There were no significant differences in the value of IL-1β,IL-18,arterial partial pressure of carbon dioxide(PaCO2),arterial partial pressure of oxygen(PaO2) before treatment between two groups. Compared with the blank control group, the levels of serum IL-1β,IL-18 in patient with AECOPD were increased significantly( P<0.01). When compared with before treatment and with the control group, the levels of IL-1β,IL-18,PaCO2 decreased more significantly in the treatment group after treatment.The PaO2 in treatment group was higher than in control group. There were significant differences between two groups.[Conclusions] Salvianolate injection can reduce the secretion IL-1β, IL-18 in patient with AECOPD, which maybe through certain anti-inflammatory effects to improve clinical efficacy of COPD pa-tients.
