Objective To explore the effects of sleep-wake rhythm intervention on blood cells in mice with aplastic anemia and its possible mechanisms of action by observing the changes in peripheral blood cell count and plasma circadian rhythm regulatory factors (MT, NE) in mice with aplastic anemia whose sleep-wake rhythm has been intervened. Methods Male C57BL/6 mice were randomly divided into the experimental groups ［sleep-wake rhythm intervention groups (sleep intervention group, wakefulness intervention group, sleep-wake intervention group) and sleep-wake non-intervention group］ and normal control group. In the experimental groups, we established the models of aplastic anemia in mice, while the mice in the normal control group did not undergo the model induction. The sleep-wake rhythm was maintained normally in the sleep-wake rhythm non-intervention group and the normal control group. The mice in the wakefulness intervention group and sleep intervention group received 24-hour light exposure and 24-hour sleep intervention, respectively. In the sleep-wake intervention group, sleep and wakefulness patterns were reversed for the first 3 days and the opposite in the following 3 days. Each group underwent a 9-day intervention period. Peripheral blood cell counts were measured in all groups on the day before intervention and on the 6th day after intervention. ELISA was used to measure the levels of MT, NE, OX, and PGE2 in the plasma and bone marrow of mice in the experimental and control groups before intervention. Plasma MT and NE levels were measured in each group on the day before intervention and on the 3rd, 6th, and 9th days after intervention. Results ① Comparison of blood cell counts before and after intervention in each group： Prior to intervention, compared with the normal control group, the experimental group had lower WBC, RBC, PLT counts, and HGB levels （all P<0. 01). On the 6th day of sleep-wake rhythm intervention, compared with the normal control group, the sleep-wake rhythm non-intervention group and sleep intervention group had lower WBC, RBC, and HGB levels （all P< 0. 01). The wakefulness intervention group and sleep-wake intervention group had lower WBC and HGB levels, but higher PLT levels in comparison with those of the sleep-wake rhythm non-intervention group （all P<0. 01). Compared with the sleep-wake rhythm non-intervention group, the wakefulness intervention group and sleep-wake intervention group had higher RBC and HGB levels （all P<0. 01). Compared with the sleep intervention group, the wakefulness intervention group and sleep-wake intervention group had higher PLT levels （all P<0. 05). ② Comparison of plasma MT and NE levels before and after intervention in each group： On the 3rd day of intervention, compared with the normal control group, the sleepwake rhythm non-intervention group and wakefulness intervention group had higher plasma MT levels （all P<0. 01). Com‐ pared with the sleep-wake rhythm non-intervention group, the wakefulness intervention group had higher plasma MT level （P<0. 01), while the sleep-wake intervention group had lower plasma MT level （P<0. 05). Compared with the sleep intervention group, both the wakefulness intervention group and sleep-wake intervention group had higher plasma MT levels （both P<0. 05). On the 6th day of intervention, there were no statistically significant differences in plasma MT levels among the groups, but a pattern emerged with the sleep-wake intervention group > sleep-wake rhythm non-intervention group > normal control group. On the 3rd day of intervention, compared with the normal control group, the sleep-wake intervention group had higher plasma NE level （P<0. 05). Compared with the sleep-wake rhythm non-intervention group, sleep intervention group, and wakefulness intervention group, the sleep-wake intervention group had higher plasma NE levels （all P<0. 05). On the 6th day of intervention, compared with the normal control group, the wakefulness intervention group had higher plasma NE level （P<0. 05), while the sleep-wake intervention group had lower plasma NE level （P< 0. 05). On the 9th day of intervention, compared with the normal control group and sleep intervention group, the sleepwake intervention group had higher NE level （both P<0. 05). Conclusions In mice with aplastic anemia whose sleepwake rhythm is intervened, there is an increase in peripheral blood cell count, as well as elevated levels of plasma MT and NE, indicating intervention in both sleep and wakefulness rhythms. Disrupted sleep-wake rhythm intervention may contribute to the elevation of blood cell count in mice with aplastic anemia by regulating MT and NE levels. [ABSTRACT FROM AUTHOR]

Objective To investigate the predictive value of serum intestinal fatty-acid binding protein (I-FABP) and smooth muscle 22 (SM22) levels on intestinal necrosis in patients with acute mesenteric ischemia (AMI). Methods Totally 167 patients with AMI were divided into the intestinal necrosis group（58 cases) and non-intestinal necrosis group (109 cases). The clinical data of AMI patients were collected, and the serum I-FABP and SM22 were detected by ELISA. Multivariate Logistic regression was used to analyze the influencing factors for intestinal necrosis in AMI, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum I-FABP and SM22 levels on intestinal necrosis in AMI. Results Multivariate Logistic regression analysis showed that lactic acid, leukocyte count, I-FABP and SM22 were the influencing factors for intestinal necrosis in AMI (all P<0. 05). The area under ROC curve of I-FABP + SM22 in predicting intestinal necrosis of AMI patients was greater than that of I-FABP and SM22 alone (both P<0. 05). Conclusion AMI patients with elevated serum levels of I-FABP and SM22 are prone to intestinal necrosis, and serum levels of I-FABP and SM22 can be used as predictors of intestinal necrosis in AMI.

Objective To investigate the effects of low expression of cancer susceptibility candidate gene 19 (CASC19) on the proliferation and apoptosis of oral squamous cell carcinoma (OSCC) cells and its mechanism. Methods Human oral keratinocyte NOK and OSCC cells SCC9, HSC3, CAL-27 were routinely cultured, and the expression of CASC19 and miR-802 in the cells was detected by real-time fluorescent quantitative PCR. SCC9 cells in the logarithmic growth phase were taken and randomly grouped. CASC19 over-expression control plasmid (pcDNA), CASC19 over-expression plasmid (pcDNA-CASC19), CASC19 inhibition expression plasmid (si-NC), CASC19 inhibition expression plasmid (si-CASC19), miR-802 negative control plasmid (miR-NC), and miR-802 mimic (miR-802) were transfected into SCC9 cells by liposome method, and they were recorded as the pcDNA group, pcDNA-CASC19 group, si-NC group, si-CASC19 group, miR-NCgroup, and miR-802 group, respectively. The si-CASC19 combined with miR-802 inhibitor negative control plasmid (anti-miR-NC) and miR-802 inhibitor (anti-miR-802) were co-transfected into SCC9 cells, which are recorded as the si-CASC19 + anti-miR-NC group and si-CASC19 + anti-miR-802 group. Real-time fluorescence quantitative PCR was used to detect the expression of miR-802 and CASC19; dualluciferase reporter assay was used to detect the targeting relationship between lncRNA CASC19 and miR-802. Western blotting was used to detect cyclin D1 (Cyclin D1), p21, and B cell lymphocytes tumor/leukemia-2 (Bcl-2), Bcl-2 related X protein ( Bax) expression; MTT assay was used to detect cell proliferation activity, and flow cytometry was used to detect apoptosis rate. Results CASC19 and miR-802 had binding sites. Compared with the pcDNA group, the relative expression of miR-802 in the pcDNA-CASC19 group was lower (P< 0. 05) ; compared with the si-NC group, the relative expression of miR-802 in the si-CASC19 group was higher. At 48 and 72 h after culture, compared with the si-NC group, the si-CASC19 group had lower OD value, higher apoptosis rate, lower Cyclin D1, Bcl-2 protein expression, and higher p21 and Bax protein expression (all P < 0. 05). Compared with the si-NC group, the si-CASC19 group had higher relative expression of miR-802, higher apoptosis rate, lower OD value after 48 and 72 hours of culture, lower relative expression of Cyclin D1 and Bcl-2 protein, and higher p21, Bax protein expression (all P <0. 05); compared with the si-CASC19 + anti-miR-NC group, the si-CASC19 + anti-miR-802 group had lower expression level of miR-802, lower apoptosis rate and OD values at 48 and 72 h after culture, higher relative expression of Cyclin D1 and Bcl-2 protein, and lower expression of p21 and Bax protein (all P < 0. 05). Conclusion Low expression of CASC19 can inhibit the proliferation of OSCC cells and promote apoptosis, and the mechanism may be related to the target regulation of miR-802 expression.

Objective To observe the expression of insulin-like growth factor 1(IGF-1) and insulin-like growth factor binding protein 3(IGFBP3) in the lung tissues of rats with chronic obstructive pulmonary disease(COPD), and to explore the mechanism of airway remodeling. Methods Twenty male Wistar rats were randomly divided into model group and control group, with 10 in each. We adopted the method of cigarette smoking to establish the COPD rat models. The rats were put into the smoking box with 10 cigarettes in, each time we lit them for 30 minutes, 3 times/d, for 90 days. The control group was fed normally. The rats were killed and lung tissues were taken, the histomorphological changes were observed by HE staining and the wall thickness of small airway was measured. The expression of IGF-1 and IGFBP3 protein in each group were detected by immunohistochemistry. The expression of IGF-1 and IGFBP3 mRNA was detected by real-time fluorescence quantitative PCR; Pearson method was used to analyze the correlation between IGF-1 and IGFBP3 protein expression and bronchiole wall thickness. Results Compared with the control group, the bronchiole wall thickness in the model group increased, and the protein and mRNA expression levels of IGF-1 and IGFBP3 in the lung tissues were enhanced(all P < 0.01). IGF-1 protein and IGFBP3 protein were both positively correlated with the thickness of bronchiole wall(r =0. 658 and 0. 654, respectively; all P < 0.01). IGF-1 protein was positively correlated with IGFBP3 protein(r = 0.810, P< 0.01). Conclusion The expression of IGF-1 and IGFBP3 in the lung tissues of COPD rats increases, which may be involved in the airway remodeling of COPD by promoting the proliferation of cells around the airway.
