Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a disease marked by apnea, hypopnea, decreased oxygen saturation, and disordered sleep structure, which is a major risk for cardiovascular disease. Recent studies have found that OSAHS patients have an increased risk of hypertension, coronary atherosclerotic heart disease, insulin resistance, type 2 diabetes, metabolic syndrome, non-alcoholic fatty liver disease, etc. And these patients have a high prevalence of obvious glucolipid metabolism disorder (GMD) , which plays an important role in cardiovascular morbidity and mortality in OSAHS. We reviewed the latest advances in the association of GMD and OSAHS, and the potential pathogenesis of OSAHS-induced GMD and insulin resistance, aiming at providing new ideas for clinical treatment of GMD in OSAHS.

It is essential to increase the use of carbohydrates as an energy source and improve protein synthesis and utilization to reduce ammonia nitrogen emissions. A 60‐day cultural experiment was conducted to assess the impact of resistant starch (kelp meal, Laminaria japonica) replacing starch on water quality, nitrogen and phosphorus budget and microbial community of hybrid snakehead. Approximately 1350 experimental fish (11.4 ± 0.15 g) were randomly divided into control group (C, 20% starch) and four resistant starch groups: low replacement group (LR, 15% starch), medium replacement group (MR, 10% starch), high replacement group (HR, 5% starch) and full replacement group (FR, 0% starch). The crude protein and crude fat content of hybrid snakehead fish fed with the FR diet had the most significant improvement (P < 0.05). However, resistant starch also increased the effectiveness of nitrogen and phosphorus utilization in hybrid snakeheads, which decreased the proportion of total nitrogen and total phosphorus in tail water. The minimum nitrogen and phosphorus emission rate was when the starch level was 6.1%. Denitrifying microbes including Gemmobacter, Rhodobacter, Emticicia and Bosea have become much more prevalent in group FR (P < 0.05). In general, replacing starch with resistant starch can enhance the rate at which nitrogen and phosphorus are used in feeding, lessening water pollution and altering environmental microbial composition. Practitioner Points: Resistant starch (RS) improves whole fish nutritional content.Resistant starch improves dietary nitrogen and phosphorus utilization.Resistant starch acts as a carbon source and encourages the colonization of denitrifying bacteria in water.
