Objective To observe the influence of two feeding ways m coma patients at gastrointestinal tract complications.Methods Seventy patients were assigned randomly to two groups according to different feeding ways:entogastric continuing infusion (observation group,n=35) and entogastric manualinfusion (control group,n=35) from June 2006 to May 2007,and observed the ratio of gastrointestinal tract complications in two groups.Results Different feeding ways had significantly correlated with the complications of gastrointestinal tract.The ratio of gastrointestinal tract complications in observation group was lower (20.00%)than that in control group (42.86%).There was statistically significant difference in two groups,P＜0.05.Conclusion The ratio of gastrointestinal tract complications could obvious reduce in entogastric nutrition continuing infusion in coma patients.

Objective Spike and wave index (SWI) is of great importance for the diagnosis of electrical status epilepticus during sleep (ESES) in children patients. This study intended to compare four commonly used SWI methods with full night SWI to evaluate their performances. Methods Fifteen patients diagnosed with ESES by electroencephalogram initial report (SWI≥50%) were retrospectively analyzed,and SWI was calculated for the full night sleep(SWI),the first sleep cycle (SWI1),the first 5 minutes of the first sleep cycle (SWI15 min),the first 10 minutes (SWI10 min) and the first 15 minutes (SWI15 min). Wilcox paired test was used to compare SWI with other four SWI methods respectively. Results The SWI of all four methods was significantly different from the full night SWI (p-values of 0.003、0.002、0.002和0.001,respectively,α=0.0125). Among the 15 patients,14 (93.3%) had the trend that SWI decreased with sleep cycles overnight. Conclusion None of the four methods of SWI is a good substitute for full night SWI. The SWI tends to decrease with sleep cycles overnight,and using the first sleep cycle or anepoch of it to calculate SWI is likely to be overestimated.

Objective:To investigate the characteristic of mild cognitive impairment (MCI) in the adults aged 48 years and over in a coal mine community, and to analyze its associated risk factors.Methods:From July to October 2019, a questionnaire survey for basic information was conducted among 180 middle-aged and elderly adults who met the inclusion criteria in the Datong coal mine community. The cognitive function was evaluated by Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The effects of gender, age, years of education, sleep, living alone, physical exercise, social activities, smoking and drinking status, body mass index and chronic diseases on cognitive level were analyzed by single factor stratification and multiple linear regression.Results:There was no significant difference in the positive rate of MCI screened by MMSE and MoCA in the age groups of 48-<64, 64-<72 and 72-90 (original and corrected P>0.05); The positive rate of MCI in MoCA screening (64.4%, 66.7%, 60.9%) was significantly higher than that in MMSE (35.6%, 45.6%, 28.1%) (all P<0.05); MMSE was positively correlated with MoCA score ( r=0.762, P<0.001). With the increase of age, the scores of memory, execution and visual space detected by MoCA decreased significantly (all P<0.05), while the scores of attention, language and orientation did not change significantly (all P>0.05). Univariate stratification showed that the significant influencing factors of MMSE or MoCA scores were gender, age, years of education and sleep status (all P<0.05). Multiple linear regression analysis showed that gender ( βMMSE=-0.192; βMoCA=-0.140), years of education ( βMMSE=0.209; βMoCA=0.328) and sleep status( βMMSE=-0.162; βMoCA=-0.136) were risk factors affecting MMSE and MoCA scores ( P<0.05). Conclusions:More middle-aged and elderly adults with MCI might be observed in a coal mine community, and the main characteristics of MCI are impaired memory, executive function and visual space. To prevent and reduce the occurrence of dementia, early interventions of MCI should be carried out among the adults with female, old age, low years of education and poor sleep quality.
