Research Progress on the Correlation Between Hypertension and Gut Microbiota.

Among cardiovascular diseases, hypertension is the most important risk factor for morbidity and mortality worldwide, and its pathogenesis is complex, involving genetic, dietary and environmental factors. The characteristics of the gut microbiota can vary in response to increased blood pressure (BP) and influence the development and progression of hypertension. This paper describes five aspects of the relationship between hypertension and the gut microbiota, namely, the different types of gut microbiota, metabolites of the gut microbiota, sympathetic activation, gut-brain interactions, the effects of exercise and dietary patterns and the treatment of the gut microbiota through probiotics, faecal microbiota transplantation (FMT) and herbal remedies, providing new clues for the future prevention of hypertension.

Mediating effect of cumulative lipid profile burden on the effect of diet and obesity on hypertension incidence: a cohort study of people aged 35-65 in rural China.

Background And Objectives: Cumulative lipid profile burden is designed to dynamically measure lipid accumulation, and its effect on hypertension has been poorly studied. Our main purpose was to investigate the effect of cumulative lipid profile burden on the incidence of essential hypertension (EH) and to investigate whether cumulative lipid burden mediates the pathogenesis of the effects of diet and obesity on EH.

Subjects And Methods: A total of 1295 participants were included in the study, which started in 2017.

Association Between Hemoglobin Glycation Index and Metabolic Syndrome in Middle-Aged and Older People.

Purpose: Hemoglobin glycation index (HGI) is used to describe the difference between estimated and measured glycated hemoglobin A1c (HbA1c). The present study aimed to investigate the association between metabolic syndrome (MetS) and HGI in middle-aged and elderly Chinese.

Patients And Methods: In this cross-sectional study, a multi-stage random sampling method was used to select objects from the permanent residents aged 35 years and above living in Ganzhou, Jiangxi, China.

Inflammation mediated the effect of dietary fiber on depressive symptoms.

Background And Aims: Previous studies showed that inflammation affects depressive symptoms. Dietary fiber may be associated with inflammation and depressive symptoms. We aimed to investigate the relationship between inflammation and depressive symptoms at different levels of dietary fiber intake and to explore whether dietary fiber affects depression through inflammation.

Evaluation of carbon dioxide rebreathing during exercise assisted by noninvasive ventilation with plateau exhalation valve.

Noninvasive ventilation with a plateau exhalation valve (PEV) is often used as an adjunct to exercise to achieve a physiologic training effect in severe chronic obstructive pulmonary disease (COPD) patients. However, during exercise, with the increase of exhalation flow and respiratory rate and limited capability of PEV to exhale gases out of the circuit, it is still unknown whether CO rebreathing occurs in COPD patients ventilated during exercise assisted by single-limb circuit with a PEV. A maximal symptom-limited cycle exercise test was performed while ventilated on pressure support (inspiratory:expiratory pressure 14:4 cmHO) in 18 male patients with stable severe COPD (mean ± standard deviation, forced expiratory volume in 1 s: 29.

Functional residual capacity in beagle dogs with and without acute respiratory distress syndrome.

Background: Traditionally, the choice of tidal volume for mechanical ventilation was based on body weight (BW) and usually, predicted BW was used to correct actual BW inter-individual variations in obesity and muscle weight. The method of selecting tidal volume depended on the fact that normal lung volumes, especially functional residual capacity (FRC), were mainly determined by height (indirectly by predicted BW), sex and age in healthy persons. However, FRCs in patients with acute respiratory distress syndrome (ARDS) might not abide by the same rule and be significantly different from each other in patients with the same height and sex.

Halomonas qiaohouensis sp. nov., isolated from salt mine soil in southwest China.

Two Gram-stain negative, moderately halophilic, aerobic, motile bacteria, designated strains YIM QH88(T) and YIM QH103, were isolated from the Qiaohou salt mine in Yunnan, southwest China. Cells of the strains were observed to be rod-shaped and produce creamy-coloured colonies. Growth of the two strains was observed at 10-45 °C (optimum 25-37 °C), at pH 6.

Use of twitch mouth pressure to assess diaphragm strength in patients with chronic obstructive pulmonary disease.

This study was undertaken to determine whether twitch mouth pressure (TwPmo) can reliably assess diaphragm strength in patients with chronic obstructive pulmonary disease (COPD) using fully automatic trigger techniques. Fifteen patients with COPD were recruited. TwPmo, twitch oesophageal pressure (TwPes) and twitch transdiaphragmtic pressure (TwPdi) were generated by phrenic nerve stimulation and were measured using an inspiratory flow trigger (40 ml/s, Experiment 1) using an inspiratory pressure trigger (-5 cmH2O, Experiment 2) and using no trigger at functional residual capacity (Experiment 3).

Starmerella jinningensis sp. nov., a yeast species isolated from flowers of Erianthus rufipilus.

Five yeast strains (Ym24403, Ym24404, Ym24408, Ym24409 and Ym24410(T)) were isolated from different flowers of Erianthus rufipilus (Gramineae), a wild plant growing in the phosphorus-rich region in Yunnan Province, south-western China, and were found to be phenotypically and genetically divergent from currently recognized yeast species. Sequence analysis of the D1/D2 domain of the large subunit rRNA gene revealed that the five strains represented a novel species described as Starmerella jinningensis sp. nov.
