Objective To explore the effect of diabetic liaison nurses on controlling blood sugar levels in patients with hyperglycemia in department other than endocrinology. Methods Four hundred diabetic patients with high blood sugar were selected from January to December, 2014 in department other than endocrinology. They were divided randomly into 2 groups equally:the control group and the observation group. The control group received traditional nursing care, while blood sugar management was carried out by diabetic liaison nurse in the observation group. Result Pre-discharge sugar metabolism in the observation group was significantly better than that in the control group (P<0.05). Conclusion The diabetic liaison nurses in other departments than the endocrinology department can help control blood sugar levels in patients with hyperglycemiain.

Objective To investigate the effect of seasonal and meteorological factors on the onset of stroke in Qinghai Plateau area.Methods Patients with stroke admitted to Qinghai Provincial People's Hospital from December 1,2011 to November 30,2016 were enrolled retrospectively.The meteorological data provided by Qinghai Meteorological Bureau were used to analyze the distribution of the number of cases in different seasons in Qinghai area and the relationship between the incidence of stroke and plateau meteorological factors.Results A total of 9 412 patients with acute ischemic stroke were enrolled,aged 15～95 years.There were significant statistical differences in the number of cases of ischemic stroke,cerebral hemorrhage,and subarachnoid hemorrhage in different seasons (all P ＜ 0.05).Among them,the number of cases with ischemic stroke increased first and then gradually decreased with the changes of spring,summer,fall and winter,while cerebral hemorrhage and subarachnoid hemorrhage showed a trend of decreasing first and then increasing gradually.There were significant differences in the number of cases in different relative humidity,temperature,and temperature differences (all P ＜ 0.05).Conclusion There are seasonal differences in the incidence of stroke in the plateau area,which may be associated with the influence of plateau meteorological factors.

Objective:To assess the efficacy of different non-drug smoking cessation interventions on smoking cessation among the high-risk populations of lung cancer screening by network meta-analysis.Methods:PubMed, MEDLINE (Ovid), PsychINFO, CNKI, WanFang and VIP databases were searched for randomized controlled clinical trials published from January 2010 to September 2020.According to the eligibility criteria, the retrieval literature was screened, the quality evaluation and data extraction were conducted, then, the statistical analysis was performed by using the Stata 14.0 software.Results:A total of 28 trials were included, including 34 640 cases of high-risk population, involving intervention measures, including 5R short quit smoking intervention, cognitive behavior therapy, award model quit smoking intervention, motivational interview, network intervention, telephone intervention, incentive mechanism plus telephone intervention, network plus telephone intervention, conventional treatment and blank group.The results of network meta-analysis showed that on the 7-day follow-up of 6 months, according to the score of SUCRA, the ranking of smoking cessation rate was 5R short smoking cessation intervention (0.88), cognitive behavior therapy (0.85), AWARD model smoking cessation intervention (0.80), incentive mechanism plus telephone intervention (0.73), motivational interview (0.53), Internet plus telephone intervention (0.40), Internet intervention (0.37), telephone intervention (0.31), conventional treatment (0.13) and blank group (0.03). However, on the 7-day smoking cessation rate of 12-month follow-up, the ranking of smoking cessation rate was 5R short smoking cessation intervention (0.94), AWARD model smoking cessation intervention (0.81), motivational interview (0.51), network intervention (0.40), telephone intervention (0.19) and conventional treatment (0.14).Conclusions:The existing evidence shows that no matter the length of follow-up, 5R short smoking cessation intervention has the best effect on smoking cessation in high-risk population of lung cancer screening.

Objective:To investigate the effect of Mediterranean diet on blood glucose control and cardiovascular risk factors in patients with type 2 diabetes.Methods:As to December 2021, the PubMed, Cochrance Central Register of Controlled Trials and Cochrance Database, Cochranc Library, Embase, China National Knowledge Infrastructure and Wanfang Medical Network system were searched for clinical randomized controlled trials(RCTs) of Mediterranean diet in patients with type 2 diabetes to conduct Meta-analysis The main observation index were cardiovascular risk factors, and the mean difference and its 95% confidence interval were used to estimate the effect size.Results:There were six RCTs, and 1181 patients met the inclusion criteria and entered the Meta-analysis. Compared with the control group, the intervention group can significantly reduce the level of systolic blood pressure ( MD=-1.20, 95% CI-2.21 to -0.19) and diastolic blood pressure ( MD=-4.17, 95% CI-7.12 to -1.22) in patients with type 2 diabetes mellitus, but there were no significant difference in the level of TC ( MD=2.92, 95% CI-0.84 to-6.67), HDL ( MD=2.33, 95% CI-0.27 to -4.92) and LDL ( MD=-2.34, 95% CI-5.67 to -0.99) between the two groups (all P>0.05). Conclusions:The meta-analysis provided evidence the Mediterranean diet showed the beneficial improvements in blood pressure glycemic control, but the effect of Mediterranean diet on lipid profile was not significant, which needed further verification.
