BACKGROUND: Physiological functions, structural fold and unfolding of neuronal calcium sensor-1 (NCS-1) have been explored in a series of experiments, and then the possible mechanism models and key factors for remaining the structural stability are raised. But many functional models cannot be verified due to the limitations of resolution of the time and space and complex protein structure. The experimental phenomena and hypothesis or models may be tested at the atom levels by molecular dynamics, and the new structure may be predicted to provide basis for model establishment and functional mechanisms. OBJECTIVE: To overview the research process of physiological functions and mechanisms of NCS-1 using the experimental method and molecular dynamics simulations, thereby providing basis for future research.METHODS: PubMed database was retrieved for the literatures addressing NCS-1 using the English subject term Neuronal Calcium Sensor-1 or Neuronal Calcium Sensor1 or Neuronal Calcium Sensor 1 or NCS-1. Finally, 72 articles were included in result analysis based on the inclusion and exclusion criteria. RESULTS AND CONCLUSION: The theoretical models of NCS-1 in secretion regulation, dopamine D2 receptor regulation, adenosine A2A receptor regulation in hepatocytes and Ca2+ regulation in myocardial cytoplasm and nuclei with different stimuli are put forward. The key factors to remaining structural stability are analyzed and summarized by modular dynamics simulation in view of structure. It is recommended to combine these two methods in order to deeply understand the protein functional mechanisms, thereby pushing the in-depth study.

OBJECTIVE:To evaluate the effects of minidose aspirin on blood uric acid,creatinine and urea nitrogen in hyperuricemia model mice.METHODS:75 mice were randomly assigned to receive 0.5% CMC-Na(normal control group and hyperuricemia control group)or aspirin(12.5,25,50 mg?kg-1?d-1)q.d for 1 week.Then all the mice except the normal control group were intraperitoneally administered with uric acid to establish hyperuricemia model.1 h later,the blood sample was collected for determination of uric acid,creatinine and urea nitrogen.RESULTS:As compared with hyperuricemia control group,mini-dose aspirin had no apparent effect on creatinine and urea nitrogen,but remarkably increased the level of blood uric acid(P

Objective To investigate the effects of solution focused approach on the hope level of patients with epilepsy. Methods A total of 83 patients with epilepsy were randomly divided into the observation group and the control group, 42 cases in the observation group, 41 cases in the control group. The control group was given traditional nursing care, the observation group was given nursing intervention based on solution focused approach. Two groups were surveyed with Herth Hope Index (HHI), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) before and after the intervention. Results Before the intervention, HHI of the observation group and the control group scored 24.95 ± 1.92 and 24.56 ± 3.23 respectively. After intervention the scores increased to 28.85 ± 1.81 and 25.31 ± 3.35. After intervention, HHI and each dimension of the observation group scored higher than those before intervention and the control group, the difference was statistically significant (t=-4.75, 5.84, P < 0.01). Before the intervention, SAS scores in the observation group and the control group were 56.41 ± 5.97 and 56.28 ± 6.14, SDS scores were 53.72 ± 8.41 and 53.47 ± 8.26, there was no statistically significant difference between the 2 groups (t=0.09, 0.13, P > 0.05). After intervention SAS scores the observation group and the control group were 41.65 ± 6.22 and 49.72 ± 5.86, SDS scores were 44.57 ± 5.83 and 49.73 ± 6.24, there was significant difference between 2 groups (t=5.67, 3.20, P < 0.01). Intra group comparison of the observation showed that there was significant difference in SAS and SDS scores before and after the intervention (t=10.27, 5.36, P < 0.01). Intra group comparison of the control group also showed statistical difference in SAS and SDS scores (t=4.65, 2.17, P<0.05 or 0.01). Conclusions The solution focused approach can improve the psychological status of patients with epilepsy, improve the level of hope, promote the rehabilitation of patients.
