In order to investigate the regulative function of telomerase and phosphorylated (activated) extracellular regulated protein kinase (ERK) 1 and 2 in the leukemic cell lines HL-60 and K562 proliferation inhibition and apoptosis, three chemotherapeutic drugs Harringtonine (HRT), Vincristine (VCR) and Etoposide (Vp16) were selected as inducers. The proliferation inhibition rate was detected by MTT method, the cell cycle and cell apoptosis was analyzed by flow cytometry and the telomerase activity was detected by the telomeric repeat amplification protocol (TRAP) assay and bioluminescence analysis method. The phosphorylated ERK1/2 protein expression was detected by western blot method. The results showed that HRT, VCR and Vp16 could inhibit cell proliferation, induce apoptosis, inhibit telomerase activity and down-regulate the protein expression of phosphorylated ERK. It was suggested that ERK signal transduction pathway was involved in the down-regulation of telomerase activity and the onset of apoptosis in the leukemic cells treated by HRT, VCR and Vp16.

Objective:To summarize the evaluation and management of early enteral nutrition tolerance in a patient with refractory status epilepticus after ketogenic diet.Methods:Nursing essentials were as follows: Individualized enteral nutrition tolerance assessment was given every 4 hours after ketogenic diet, including nausea, vomiting, abdominal distention, diarrhea, gastric retention and upper gastrointestinal bleeding; when patients suffered from intolerance to ketogenic diet, nasointestinal tube was retained to upper jejunum, ketogenic diet was diluted, dietary fiber and trypsin were increased. Intake of preparations and probiotics could reduce the incidence of diarrhea and gastric retention. Blood sugar and ketone levels were monitored every 4 hours to evaluate the therapeutic effect of ketogenic diet by Engel grading. Early active mobility was carried out to reduce the mechanical ventilation time and improve limb muscle strength.Results:After careful treatment and nursing, ketogenic diet progressed smoothly and gastrointestinal intolerance improved significantly. On the 30th day of admission, Engel was grade I. The patient was stable with no functional epileptic attack. On the 66th day after admission, the patient was successfully taken off line and transferred to the general treatment area. During the period of hospitalization, there was no nursing related complications such as pressure ulcer, and the patient recovered and discharged.Conclusion:Individualized assessment and management of enteral nutrition tolerance can effectively reduce the related complications and improve the prognosis of patients with refractory status epilepticus who take ketogenic diet.

Objective To investigate the effect of acceptance and commitment therapy intervention on post-traumatic growth of patients with concomitant brain injury in group context. Methods From January 2016 to January 2017, 40 patients with recovery from craniocerebral injury such as car accidents and work-related injuries were set as the control group, and regular health education and guidance were conducted twice a week for 6 times. From February to February 2018, 42 patients with recovery from craniocerebral injury such as car accidents and work-related injuries were set as observation groups. The observation group was given a 3-week group acceptance and commitment therapy intervention on the basis of the control group. Before and after the intervention, the simplified Chinese version of the post-traumatic growth rating scale was used for evaluation. Results After intervention, the total scores of life perception, personal strength, new possibility, relationship with others, self-transformation and post-traumatic growth were (18.68 ± 3.86), (11.35 ± 2.67), (10.49 ± 2.48), (14.35 ± 2.95), (10.49 ± 2.32), (65.36 ± 14.28) points in the observation group, and were (13.23±3.10), (9.46±2.41), (6.82±1.72), (11.81±2.06), (7.91 ± 1.89), (49.23 ± 11.18) points the control group, the difference between the two groups were statistically significant (t=7.325-8.289, both P<0.05). Conclusions Group acceptance and commitment therapy intervention can improve the post-traumatic growth level of patients with recovery period of craniocerebral injury, and provide a reliable basis for clinical medical staff to promote positive psychological adjustment of patients with recovery period of craniocerebral injury.

Objective To investigate the effect of LncRNA-p21 on the proliferation, migration and invasion of non-small cell lung cancer A549 cells by regulating Notch signaling pathway. Methods The pcDNA-lincRNA-p21 and empty plasmid pcDNA were transfected into A549 cells, and they were divided into overexpression group and empty vector group. Cells from the stably-transfected overexpression group were added with the Notch signaling pathway specific activator Jagged1 protein and set as the Notch activator group. In addition, the cells without treatment were taken as the control group. Cell proliferation, migration and invasion of each group were detected by MTT method, scratch test and Transwell cell test. The expressions of Notch 1, HES-1, NICD, E-cadherin, Vimentin mRNA and protein were detected by RT-qPCR and Western blot. Results The A value of MTT test at 24, 48 and 72 hours in the overexpression group was lower than those in the control group, empty vector group and Notch activator group, and the Notch activator group was higher than the control group and the empty vector group (P < 0.05). The cell migration rate, the number of transmembrane cells and the relative expressions of Notch1, HES-1, NICD, Vimentin mRNA and protein of overexpression group at 48 hours were lower than those of the control group, empty vector group and Notch activator group, and the Notch activator group was lower than the control group and the empty vector group (P < 0.05). The relative expressions of E-cadherin mRNA and protein of overexpression group were higher than those of control group, empty vector group and Notch activator group, and the Notch activator group was higher than the control group and the empty vector group (P < 0.05). Conclusion Overexpression of LncRNA-p21 gene could inhibit the proliferation, migration and invasion of non-small cell lung cancer A549 cells. Its regulatory mechanism may be related to inhibiting Notch signaling pathway, thereby blocking the epithelial-mesenchymal transition of A549 cells.
