ABSTRACT
Respiratory microbiome is extensively involved in human life activities and affects lung health and disease states through metabolism and immune regulation. Based on 16S rRNA gene sequencing and other methods, it is obvious that the diversity and the changes in the structure of respiratory microbiome and the dominant proliferation of pathogens are strongly related to the occurrence, development and clinical prognosis of ventilator-associated pneumonia (VAP). The mechanism by which respiratory microbiota promotes the clearance of pathogens may include the following aspects: ① pre-stimulating innate immune system to increase the number of immune effector cells; ② regulating pattern recognition receptor (PRR) to moderately promote the production of cytokines; ③ inducing the differentiation of neutrophils into specific subtypes and increasing the expression of antimicrobial genes; ④ producing free fatty acids and organic compounds that are capable of positively modulating the immune system. In conclusion, intervention of microbiome is beneficial to VAP patients. Therefore, this review illustrates the changes of respiratory flora in VAP and its effect on host immunity. At the same time, based on the review of the adjuvant treatment of VAP with probiotics, we put forward the prospect of respiratory commensal bacteria as a new clinical probiotic, in order to deepen the clinical understanding of the role of respiratory flora in VAP, and then provide new ideas for the evaluation of treatment and prognosis.
ABSTRACT
Objective@#To preliminarily develop Health Literacy Scale for pupils, providing a tool for dynamic monitoring and related health literacy research among pupils.@*Methods@#Through policy and literature review, the health literacy evaluation index system of pupils was established. Through two rounds of expert consultation, the evaluation index system and scale item pool of three levels in primary school were formed, and "Evaluation Scale 1.0" was developed. Through two panel discussions, health education experts, teachers and students were invited to provide advices on the content, expression and structure of scale 1.0, turning it into "Evaluation Scale 2.0", and completing the preliminary development of the scale.@*Results@#The health literacy assessment index system of primary school students includes three levels，including level-1 was Grade 1-2, level-2 was Grade 3-4,level-3 was Grade 5-6, covering two level indexes. The scale for primary school students contained five horizontal dimensions and four vertical dimensions. In the Delphi consultation, the response rate was 100%, and the authority coefficient was 0.85. After item selection and modification, the final version of level-1, level-2 and level-3 scales contained 36, 44 and 50 items respectively.@*Conclusion@#The development of Health Literacy Evaluation Scale for pupils has high applicability and practical value.
ABSTRACT
Objective:To explore the clinical curative effect of nifedipine controlled-release tablets combined with telmisartan on diabetes mellitus combined with hypertension and their influences on serum homocysteine (Hcy) and C-reactive protein (CRP).Methods:Eighty-four patients with diabetes mellitus and hypertension who were admitted to Huainan First People′s Hospital from February 2016 to November 2019 were enrolled. They were divided into combination group and control group by random number table method, with 42 cases in each group. The control group was treated with nifedipine controlled-release tablets, while combination group was additionally treated with telmisartan. Both groups were continuously treated for 4 weeks. After treatment, clinical curative effect in both groups was evaluated. The levels of diastolic blood pressure (DBP), systolic blood pressure (SBP), fasting plasma glucose (FPG), 2 h postprandial blood glucose (2 hPG), glycosylated hemoglobin (HbA 1c), total cholesterol (TC), triacylglycerol (TG), Hcy and CRP were measured before and after treatment. The number of cases with adverse reactions was recorded. Results:After treatment, total response rate in combination group was significantly higher than that in control group [92.24%(40/42) vs. 80.95%(34/42)] ( P<0.05). After treatment, there were no significant differences in FPG, 2 hPG and HbA 1c between the two groups ( P>0.05). After treatment, the levels of SBP, DBP, TC, TG, CRP and Hcy in combination group were significantly lower than those in control group [(132.64 ± 7.53) mmHg)(1 mmHg=0.133 kPa) vs. (142.81 ± 4.63) mmHg, (79.63 ± 6.84) mmHg vs.(85.71 ± 5.86) mmHg, (4.87 ± 0.61) mmol/L vs. (5.14 ± 0.62) mmol/L, (1.57 ± 0.41) mmol/L vs.(1.76 ± 0.45) mmol/L,(8.76 ± 1.53) mg/L vs. (9.51 ± 1.86) mg/L, (12.52 ± 1.97) μmol/L vs.(13.48 ± 2.36) μmol/L]( P<0.05). During treatment period, there was no significant difference in incidence of adverse reactions between combination group and control group [16.67% (7/42) vs. 19.05%(8/42)]( P>0.05). Conclusions:The clinical curative effect of nifedipine controlled-release tablets combined with telmisartan is good on diabetes mellitus combined with hypertension, which can regulate blood pressure, blood lipids, Hcy and CRP levels, and relieve disease progression, with good safety.
ABSTRACT
<p><b>OBJECTIVE</b>A study was conducted to investigate the effects of Porphyromonas gingivalis lipopolysaccharide (Pg-LPS) on the expression of regulated upon activation normal T-cell expressed and secreted (RANTES) and fractalkine in human umbilical vein endothelial cells (HUVECs).</p><p><b>METHODS</b>HUVECs were incubated with different concentrations of Pg-LPS (200, 500, and 1000 ng x mL(-1)) for 1, 6, 12, and 24 h, respectively. Then real time quantitative polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent method (ELISA) were adopted to detect the protein levels and mRNA levels of RANTES and fractalkine.</p><p><b>RESULTS</b>The RANTES protein levels and mRNA levels, as well as fractalkine mRNA levels, were significantly higher in all experimental groups of 1, 6, and 12 h than in the control group (P<0.05), except the expression of RANTES mRNA in 200 ng x mL(-1) group of 12 h and RANTES protein in 200 ng x mL(-1) group of 1 h. The expression levels of RANTES mRNA and fractalkine mRNA were highest in 1000 ng x mL(-1) group of 6 h and were 4.88- and 6.20-fold higher, respectively, than those in the control group. The expression levels of RANTES protein, mRNA, and fractalkine mRNA decreased 6 h after stimulation, and were significantly higher than those in the control group (P<0.05) in the RANTES and fractalkine in HUVEC, and such expression is important in the development of atherosclerosis 500 ng x mL(-1) group of 24 h. There was a significant difference between the expression of fractalkine mRNA in 1000 ng x mL(-1) group of 6 and 12 h than in the control group (P<0.05).</p><p><b>CONCLUSION</b>Pg-LPS infection might up-regulate the expression of RANTES and fractalkine in HUVEC, and such expression is important in the development of atherosclerosis.</p>

Epidemiology studies have demonstrated inconsistent associations between type 2 diabetes mellitus and the risk of malignant melanoma. To this end, the aim was to perform a meta-analysis of cohort studies. Medline, PubMed, Embase and the Cochrane Library were searched up to February 2014. Cohort studies addressing the relative risk of type 2 diabetes mellitus on malignant melanoma were included in this meta-analysis. The Newcastle-Ottawa Scale was applied for quality evaluation. The pooled relative risks with the corresponding 95% confidence intervals [95% CIs] were calculated by using random-effects or random-effects model. Heterogeneity and publication bias were evaluated by I[2] and funnel plot analysis, respectively. Data was analyzed using STATA 11.0. A total of 9 independent cohorts from 8 manuscripts were entered this meta-analysis. Type 2 diabetes mellitus was slightly associated with an increased risk of malignant melanoma, and the pooled relative risk was 1.15 [95% CI, 1.00-1.32] in diabetes compared with non-diabetes with significant evidence of heterogeneity among these studies [P=0.016, I[2] =57.6%]. For the studies adjusted for age, gender and obesity, the relative risks were 1.21[95% CI, 1.03-1.42], 1.17 [95% CI, 1.01-1.35] and 1.11 [95% CI, 1.00-1.24], respectively. For the population-based studies in which case cohort established, the relative risk was 1.85 [95% CI, 1.31-2.62]. Type 2 diabetes might be an independent risk factor for malignant melanoma. Further studies are needed to specifically test the effect, and fully elucidate the underlying pathophysiologic mechanisms
