Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous syestem (CNS) triggered by an autoimmune mechanism, which is the main cause of neurological disability in young people. In MS, a variety of glial cells participate in the pathogenesis and development of the disease, and oligodendrocytes (OL) and myelin cytes are destroyed by autoimmune mediated inflammation. Impaired OL production of oligodendrocyte progenitor cells (OPC) leads to persistent demyelination, myelin fragment accumulation and axonal injury, with clinical manifestation of CNS disability. Microglia (MG), which is involved in the inflammatory response and removal of myelin debris, plays a pivotal role in OPC differentiation and OL maturation, thereby directly or indirectly influencing the process of myelin regeneration. An interactive mechanism exists between these 2 components. The comprehension of the interrelationship between the 2 factors can provide enhanced insights into the pathogenesis of MS and facilitate the development of novel therapeutic strategies, thereby addressing pivotal scientific challenges encountered in clinical management of MS. Therefore, this review summarizes the dynamic changes of microglia in MS and its classic animal models, explores the internal relationship between MG and OL in this process, and focuses on the beneficial effects of targeted regulation of microglia, thereby promoting OPC differentiation and myelin regeneration, in order to provide a new research direction for MS treatment.

Objective:To explore the application effect of early warning model of chemotherapy complications in nursing care of non-small cell lung cancer during chemotherapy.Methods:By using convenient sampling method, 106 patients with non-small cell lung cancer treated by chemotherapy in the Thoracic Surgery Department of the First Affiliated Hospital of Zhengzhou University from January 2016 to February 2019 were selected as the study objects. According to the time of admission, they were divided into the control group ( n=52) and the observation group ( n=54) . The control group was given routine nursing care during chemotherapy, while the observation group was given nursing care through early warning model of chemotherapy complications during chemotherapy. Hamilton Anxiety Scale (HAMA) , Hamilton Depression Scale (HAMD) and European Organization for the Research and Treatment of Cancer QLQ-C30 (EORTCQLQ-C30) were used to compare the intervention effect of the two groups, and the incidence of complications during chemotherapy was counted. Results:The total incidence of complications was 26.92% (14/52) in the observation group and 46.15% (24/52) in the control group, the difference was statistically significant (χ 2=4.147, P<0.05) . Three months after the intervention, HAMA (9.87±4.25) and HAMD (15.54±3.58) in the observation group were lower than those in the control group; the differences were statistically significant ( t=4.738, 8.296; P<0.05) . The functional score, symptom score, overall quality of life score and single measurement item score of the observation group were higher than those of the control group with statistical differences ( P<0.05) . Conclusions:During chemotherapy for non-small cell lung cancer, nursing through the early warning model of chemotherapy complications can reduce the incidence of chemotherapy complications, alleviate the negative emotions of patients, and improve the quality of life, which is worthy of clinical application.

Objective: To investigate the therapeutic effect of dendritic cell-induced killer cells (DC-CIK) combined with 5-fluorouracil (5-FU) and loaded with CD133+ HT-29 cell lysate or RNA on mice bearing colon cancer HT-29 cell transplanted tumor, and to explore the underlying mechanism. Methods: Colon cancer xenograft model was established in BALB /c nude mice by using human colon cancer HT-29 cells at logarithmic growth phase; Antigen-free DC-CIK, 5-FU+DC-CIK, R+DC-CIK (loaded with total RNA of CD133+ cells), L+DC-CIK (loaded with CD133+ cell lysate), 5-FU and normal saline were respectively injected into transplanted mice, and the treatment efficacies on the growth of transplanted tumor in each group after three treatment cycles were observed, and the tumor growth curve was drawn. The nude mice were sacrificed by cervical dislocation and the tumor volume and body weight were measured. qPCR was used to detect the expression of AKT mRNA in transplanted tumor tissue, and WB was used to detect the expression of phosphorylated AKT protein. Results: After treatment, the body mass of nude mice in R+DC-CIK group, L+DC-CIK group and 5-FU+DC-CIK group increased steadily, while the body mass of nude mice in DC-CIK group and 5-FU group decreased gradually; the tumor growth speed of nude mice in R+DC-CIK group, 5-FU+DC-CIK group and L+DC-CIK group was significantly slower than that of the control group (P<0.05). Compared with 5-FU and DC-CIK alone, the combined treatment with loaded lysate/RNA had more sig nificant effect on mRNA and protein expressions of AKT(P<0.05). Conclusion: The effect of DC-CIKwithdifferentloadingoritscombinationwith5-FUisbetterthanthatofchemotherapy alone. One of the mechanisms is related to the down-regulation ofAKT level.

Objective To analyze the expression of interleukin 16 (IL-16) in atherosclerosis (AS) patients, and to study the roles of IL-16in the pathogenesis of AS.Methods Thirty AS patients in Affiliated Hospital of Jining Medical College from August 2015to August 2016were randomly selected as the case group and twenty-nine healthy subjects were selected as the healthy control group.Peripheral blood of the subjects were collected.IL-16levels were determined with enzyme-linked immunosorbent assay (ELISA).Reverse transcriptase-polymerase chain reaction was applied to analyze IL-16mRNA level.IL-16expression in the atherosclerotic plaque samples was detected with immunohistochemical analysis.IL-16expression in aortic atherosclerotic plaque of AS patients and atherosclerotic ApoE-/-mice were analyzed by immunohistochemical staining.The aortic plaque changes of AS mice injected intraperitoneally with recombinant IL-16were detected.Results Both IL-16protein levels and IL-16mRNA levels were higher in case group than those of healthy control group, the difference was statistically significant (P＜0.05).The IL-16mRNA was highly expressed in the atherosclerotic plaque.The aortic plaque area of the mice underwent IL-16intraperitoneal injection were decreased while the plaque stability increased.Conclusion IL-16levels elevated in both AS patients and AS mice, which suggested that IL-16might play aprotective role against AS.

Objective? To explore the effects of grading health education model on self-care behavior and health behavior among elderly bronchiectasis patients outside hospital. Methods? From March 2015 to March 2017, we selected 120 elderly bronchiectasis patients at the First Affiliated Hospital of Zhengzhou University by convenience sampling. All of the patients were divided into control group and observation group with the method of the random number table, 60 cases in each group. Control group carried out routine health education. Observation group received the grading health education model dividing health education into three stages and pushing education content by WeChat;a total of 12 times of health education were implemented. The interventional cycle was three months between two groups. The Appraisal Self-Care Agency Scale-Reviewed (ASAS-R-C) and the Self-Rated Abilities for Health Practices Scale (SRAHP) were used to assess the self-care behavior and health behavior of patients outside hospital. Results? Before intervention, there were no statistical differences in the score of ASAS-R-C and SRAHP (P＞ 0.05). After intervention, the dimension scores of ASAS-R-C, SRAHP and the total score were higher than those before intervention with statistical differences (P＜0.05). After intervention, the scores of self-care goal, self-care skill, the total score of ASAS-R-C, health responsibility, sport management and the total score of SRAHP of intervention group were (25.62±2.18), (24.52±2.41), (74.72±6.27), (24.78±2.75), (25.21±2.16) and (98.35±8.16) higher than those of control group with statistical differences (P＜ 0.05). Conclusions? Grading health education model is propitious for elderly bronchiectasis patients to clear the nursing goal, improve nursing skills, enhance their health responsibility and improve their sport management abilities which is worthy of popularization and application.

Objective To investigate the status of exercise autonomy of chronic obstructive pulmonary disease (COPD) patients at stationary phase in community and to analyze the influencing factors of exercise autonomy so as to guide the external hospital control of COPD. Methods Totals of 124 COPD patients at stationary phase from three target communities in the area of the First Affiliated Hospital of Zhengzhou University were investigated by the method of convenience sampling. We analyzed the status of exercise among them. Non-conditional Logistic stepwise regression was used to determine the influencing factors of exercise autonomy. Results A total of 122 valid questionaires were collected. Among 122 patient, 51 (41.80%) patients never carried out, 33 (27.05%) occasionally carried out and 38 (31.15%) persisted in respiratory function exercise. Besides, 44 (36.07%) patients never carried out, 36 (29.51%) occasionally carried out and 42 (34.43%) persisted in all-round exercise. There were 53 patients with the good exercise autonomy. The frequent hospitalization was the independent protective factor of patients' exercise autonomy (P＜ 0.05). Conclusions COPD patients at stationary phase in community have poor exercise autonomy. Patients with more frequent hospitalization tend to carry out exercise more actively.
