Objective To explore the influence of non-drug bundle of care on incidence rate of VAP. Methods Prospective analysis was performed on patients with mechanical ventilation in ICU from January 2015 to December 2016. The patients were assessed daily, monitored for target, and divided into infected group and non-infected group according to incidence of VAP. Relationship between incidence of VAP and measures taken in non-drug bundle of care, with all data statistically analyzed by SPSS 19.0 for windows. Results A total of 1 326 cases were collected in this study, with 109 infected cases and 1 217 non-infected cases. It was shown in related single factor analysis that factors influencing incidence of VAP included mode of tracheal intubation (whether with subglottic secretion drainage or not), severity of clinical conditions of the patients (APACHEⅡ score >18 points), time of mechanical ventilation (>7 days), hand sanitation, the patients' compliance to operations like elevation of bed head (>30°), oral care, assessment of tracheotomy cuff pressure, monitoring of gastric residual volume, timely dumping of condensed water, and unobstructed subglottic secretion drainage (P< 0.05). It was shown in Logistic regression analysis that mechanical ventilation time was an independent factor affecting incidence of VAP (OR=30.536, P<0.01). Conclusions According to non-drug bundle of care strategies, daily evaluation should be conducted. Early off-machine and early extubation can reduce incidence of VAP.

ObjectiveTo investigate the changes of intestinal microbiota in type 2 diabetic diarrhea （T2DD） patients with dampness-heat syndrome and spleen-kidney deficiency syndrome. MethodT2DD patients who were admitted to the Department of Endocrinology Ⅰ of the Affiliated Hospital of Shaanxi University of Chinese Medicine from March 2020 to May 2021 were selected， including 14 patients with type 2 diabetes mellitus （T2DM）， 12 T2DD patients with dampness-heat syndrome， and 13 T2DD patients with spleen-kidney deficiency syndrome. Twelve healthy subjects receiving medical examination were selected as control group. Their body mass index （BMI）， fasting plasma glucose （FPG）， 2 h postprandial blood glucose （2 h PBG） and glycosylated hemoglobin （HbA1c） were compared. Fecal samples were collected for DNA extraction to build a database. High-throughput 16S rDNA sequencing was used to compare the composition of intestinal microbiota and the differential bacteria among the four groups. ResultCompared with the conditions in control group， the levels of FPG， 2 h PBG and HbA1c in the other groups were increased （P<0.05）. Alpha diversity showed no significant difference in species richness， evenness and diversity of intestinal microbiota among the groups. Beta diversity indicated that intestinal microbiota tended to be consistent in each group， and there was no marked difference between groups. The top 5 phylum by relative abundance were Bacteroidetes，Proteobacteria， Firmicutes， Actinobacteria， and Fusobacteria， among which，Bacteroidetes， Proteobacteria and Firmicutes were dominant. Compared with the control group， the three diabetic groups had elevated relative abundance of Bacteroidetes while decreased relative abundance of Firmicutes. The relative abundance of Actinomycetes in spleen-kidney deficiency T2DD group was significantly higher than that in the other groups， and the relative abundance of Firmicutes and Fusobacteria in the dampness-heat T2DD group was significantly lower than that in the other groups. At the genus level， the top 10 bacteria by relative abundance were Phocaeicola， Bacteroides， Pseudescherichia， Prevotella， Bifidobacterium， Faecalibacterium， Fusobacterium， Roseburia， Citrobacter， and Cetobacterium. LEfSe analysis revealed that the relative abundance of Prevotella， Mediterraneibacter， Parabacteroides， and Fusicatenibacter in diabetic patients was remarkably higher than that in healthy patients. Bacteroides and Sutterella might be the characteristic microbiota of T2DD patients with dampness-heat syndrome， while Faecalibacterium， Limosilactobacillus， Eubacterium， Gemmiger， Enterocloster， Alistipes， Parasutterella and Oscillibacter might be the characteristic microbiota of T2DD patients with spleen-kidney deficiency syndrome. ConclusionBacteroides and Parasutterella might be the characteristic microbiota of T2DD patients with dampness-heat syndrome and spleen-kidney deficiency syndrome， respectively. This paper provided reference for studying the mechanism， diagnosis and treatment of modern traditional Chinese medicine for T2DD of dampness-heat type and spleen-kidney deficiency type.
