Effects of rapeseed oil on body composition and glucolipid metabolism in people with obesity and overweight: a systematic review and meta-analysis.

To investigate the effects of rapeseed oil on body composition, blood glucose and lipid metabolism in people with overweight and obesity compared to other cooking oils. We searched eight databases for randomized controlled studies (including randomized crossover trials). The risk of bias for the included studies was assessed using the Cochrane Risk of Bias 2.0 tool. The Grading of Recommendations Assessment Development and Evaluation (GRADE) criteria were used to evaluate the quality of the outcomes. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. Sensitivity analysis was used to check the stability of the pooled results. Statistical analysis was carried out using Review Manager 5.3 software. As a result, fifteen randomized controlled studies (including six parallel studies and nine crossover studies) were included in this study. Compared to other edible oils, rapeseed oil significantly reduced low density lipoprotein cholesterol (LDL-C) (MD = -0.14 mmol/L, 95% CI: -0.21, -0.08, I2 = 0%, P < 0.0001), apolipoprotein B (ApoB) (MD = -0.03 g/L, 95% CI: -0.05, -0.01, I2 = 0%, P = 0.0003), ApoB/ApoA1 (MD = -0.02, 95% CI: -0.04, -0.00, I2 = 0%, P = 0.02) and insulin (MD = -12.45 pmol/L, 95% CI: -19.61, -5.29, I2 = 37%, P = 0.0007) levels, and increased fasting glucose (MD = 0.16 mmol/L, 95% CI: 0.05, 0.27, I2 = 27%, P = 0.003) levels. However, the differences in body weight and body composition between rapeseed oil and control oils were not significant. In a word, rapeseed oil is effective in reducing LDL-C, ApoB and ApoB/ApoA1 levels in people with overweight and obesity, which is helpful in preventing and reducing the risk of atherosclerosis.

Effects of WB-EMS and protein supplementation on body composition, physical function, metabolism and inflammatory biomarkers in middle-aged and elderly patients with sarcopenic obesity: A meta-analysis of randomized controlled trials.

BACKGROUND: The patients with sarcopenic obesity (SO) have the characteristics of both sarcopenia and obesity, that is, less muscle mass and increased fat mass, and their morbidity, disability and mortality are higher than patients with sarcopenia or obesity alone. OBJECTIVES: To investigate the effects of whole-body electromyostimulation (WB-EMS) training and protein supplementation intervention on body composition, physical function, metabolism and inflammatory biomarkers in middle-aged and elderly patients with SO. METHODS: We searched for randomized controlled trials in seven databases, including PubMed, Web of Science, Embase, Cochrane Library, Scopus, SinoMed, and CNKI as of July 3, 2021. The methodological quality of each included study was assessed using the Physiotherapy Evidence Database (PEDro) scale. The Cochrane Risk of Bias Tool was used to assess the risk of bias. Statistical analysis was performed using Review Manager 5.3. RESULTS: Eleven randomized controlled studies with a total of 779 participants were included in this meta-analysis. WB-EMS training improved sarcopenia Z-score (MD = -1.52, 95 % CI: -2.27, -0.77, P < 0.0001) and waist circumference (WC) (MD = -1.41, 95 % CI: -2.62, -0.20, P = 0.02), and increased skeletal muscle mass index (SMI) (MD = 1.27, 95 % CI: 0.66,1.88, P < 0.0001) and appendicular skeletal muscle mass (ASMM) (MD = 0.68, 95 % CI: 0.08, 1.27, P = 0.03). Protein supplementation intervention reduced body fat rate (BF%) (MD = -1.28, 95 % CI: -1.88, -0.68, P < 0.0001, I2 = 0 %), total body fat (TBF) (MD = -0.98, 95 % CI: -1.65, -0.31, P = 0.004, I2 = 0 %) and trunk body fat mass (TBFM) (MD = -0.50, 95 % CI: -0.94, -0.06, P = 0.03, I2 = 0 %), and increased grip strength (GS) (MD = 1.13, 95 % CI: 0.06, 2.21, P = 0.04, I2 = 0 %). The combination of WB-EMS and protein supplements is beneficial to most body components and physical functions, such as SMI (MD = 1.21, 95 % CI: 0.73, 1.51, P < 0.00001, I2 = 0 %), GS (MD = 1.60, 95 % CI: 0.80, 2.40, P < 0.0001, I2 = 45 %) and walking speed (WS) (MD = 0.04, 95 % CI: 0.02, 0.06, P < 0.0001, I2 = 49 %). Compared with protein supplementation alone, WB-EMS could have an additional beneficial effect on BF% (MD = -0.92, 95 % CI: -1.80, -0.04, P = 0.04) and WC (MD = -1.03, 95 % CI: -1.70, -0.36, P = 0.003). Nevertheless, the addition of protein supplements did not provide any additional benefit compared with WB-EMS alone. In addition, there was almost no positive effect of WB-EMS and protein supplements on metabolic and inflammatory biomarkers. CONCLUSIONS: As things stand, protein supplementation intervention can effectively reduce body fat percentage, fat mass, and increase grip strength in SO patients. Both WB-EMS and protein supplementation intervention had no significant effects on metabolic and inflammatory biomarkers. WB-EMS combined with protein supplementation intervention was beneficial for SO patients in many ways. Due to the small number of studies, further studies are needed to confirm the efficacy of WB-EMS alone or in combination with protein supplementation intervention in SO patients.

The feeding of dietary Codonopsis pilosula polysaccharide enhances the immune responses, the expression of immune-related genes and the growth performance of red swamp crayfish (Procambarus clarkii).

Polysaccharides have many functions in aquatic animals and are widely used as immunopotentiators. However, despite the emergence of serious diseases, few studies have explored the effects of Codonopsis pilosula polysaccharide (CPP) on crustaceans. We studied the effects of CPP on the growth performance, nonspecific immunity, antioxidant activity and disease resistance of red swamp crayfish (Procambarus clarkii). Healthy crayfish (5.80 ± 0.1 g) were fed diets supplemented with 0% (control), 0.05%, 0.1%, 0.15%, 0.20%, and 0.30% CPP for 8 weeks. At the end of the 8-week feeding trial, the optimal final body weight (FBW), weight gain (WG), specific growth rate (SGR), and feed conversion ratio (FCR) were observed in the crayfish fed the diets with 0.15% and 0.20% CPP, followed by those fed the diet with 0.30% CPP and then those fed the diet with 0.10% CPP, whereas the values of these parameters were obtained with the control crayfish (P < 0.05). The crayfish fed the diets with 0.15% and 0.20% CPP exhibited a significantly higher total hemocyte count (THC) and significantly increased phenoloxidase (PO), lysozyme (LZM), hemocyte (Hc), acid phosphatase (ACP) and alkaline phosphatase (AKP) compared with those belonging to the other groups (P < 0.05). The crayfish fed the diets with 0.15% and 0.2% CPP exhibited significantly higher total superoxide dismutase (T-SOD) and glutathione peroxidase (GPx) activities, a significantly increased total antioxidant capacity (T-AOC) and a significantly lower malondialdehyde (MDA) content compared with the other groups (P < 0.05), which indicated that antioxidant capacity was significantly induced by the CPP-supplemented diets. Significantly upregulated expression of immune-related genes (anti-lipopolysaccharide factors (alf), peroxiredoxin (prx5), cathepsin B (ctsb), mitochondrial manganese superoxide dismutase (mtMnsod), cyclophilin A (cypa), glutathione peroxidase (gpx), Toll-like receptor 3 (tlr3), and heat shock protein 70 (hsp70)) was detected in the crayfish fed the diets supplemented with 0.15% and 0.20% CPP diet compared with the levels observed in the control crayfish. These results showed that dietary CPP supplementation greatly improved the growth, immunity and antioxidant capacities of crayfish, and according to the observed results, 0.15%-0.2% is the recommended optimal level of CPP dietary supplementation for crayfish.

Effects of hesperidin on the growth performance, antioxidant capacity, immune responses and disease resistance of red swamp crayfish (Procambarus clarkii).

We evaluated the effects of hesperidin on the nonspecific immunity, antioxidant capacity and growth performance of red swamp crayfish (Procambarus clarkii). A total of 900 healthy crayfish were randomly divided into six groups: the control group (fed the basal diet) and the HES25, HES50, HES75, HES100 and HES150 groups, which were fed the basal diet supplemented with 25, 50, 75, 100 and 150 mg kg-1 hesperidin, respectively. The feeding experiment lasted 8 weeks. The results indicated that compared with the control group, the crayfish groups supplemented with 50-150 mg kg-1 hesperidin had a decreased feed conversion ratio (FCR) and increased final body weight (FBW), specific growth rate (SGR) and weight gain (WG) (P < 0.05). The protein carbonyl content (PCC), reactive oxygen species (ROS) level and malondialdehyde (MDA) level in the hepatopancreas and hemocytes were significantly lower, while the total antioxidant capacity (T-AOC), glutathione peroxidase (GPx) activity, and superoxide dismutase (SOD) activity were significantly higher in the crayfish groups supplemented with 50-150 mg kg-1 hesperidin than in the control group. Supplementation with 50-150 mg kg-1 hesperidin significantly increased the activities of acid phosphatase (ACP), alkaline phosphatase (AKP), lysozyme (LZM), and phenoloxidase (PO) compared with the control group (P < 0.05); upregulated the mRNA expression of cyclophilin A (CypA), extracellular copper-zinc superoxide dismutase (ecCuZnSOD), GPxs, crustin, astacidin, Toll3 and heat shock protein 70 (HSP70) (P < 0.05); and decreased crayfish mortality following white spot syndrome virus (WSSV) infection. These findings indicate that dietary hesperidin supplementation at an optimum dose of 50-150 mg kg-1 may effectively improve nonspecific immunity, antioxidant capacity and growth performance in crayfish.

[Efficacy Observation of Chinese Herbal Fumigation Combined Western Drugs for Treating Sys- temic Sclerosis Complicated Pulmonary Arterial Hypertension].

Objective To observe the therapeutic efficacy and safety of Chinese herbal fumigation combined with leflunomide (LEF) and prednisone (Pred) in treatment of systemic sclerosis (SSc) complicated pulmonary arterial hypertension (PAH). Methods Totally 99 SSc patients complicated early PAH were randomly assigned to the Western drugs group (WD, 49 cases) and the integrative medicine group (IM, 50 cases). Patients in the WD group took LEF (20 mg) and Pred (15 mg) , once per day. In addition to routine WD program, those in the IM group additionally received Chinese herbal fumigation. All treatment lasted for 6 months. Raynaud's phenomenon (RP) was observed in each group before and after treatment. RP score, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), pulmonary arterial systolic pressure (PASP) , and pulmonary function were compared between the two groups before and after treatment. The clinical efficacy and adverse reactions were evaluated. Results Thirteen cases were lost due to various reasons. A total of 86 patients completed this study, 41 in the WD group and 45 in the IM group. Compared with the same group before treatment, RP score, levels of ESR and CRP all decreased in the two groups after treatment (P <0. 05). Compared with the WM group after treatment, RP score, levels of ESR and CRP were obviously lowered in the IM group after treatment (P < 0. 05). Besides, lowered differences between post-pre-values of ESR, CRP, and PASP were more obviously higher, while elevated differences between post-pre-values of total lung capacity (TLC) and carbon monoxide diffusing capacity (DLCO) were more obviously higher in the IM group (P <0. 05). The total effective rate was 93. 33% (42/45) in the IM group, obviously higher than that in the WD group [70. 73% (29/41) , P <0. 05 ]. There was no statistical difference in total adverse reaction rate between the two groups (x² =0. 019, P =0. 891). Conclusion Chinese herbal fumigation combined with WD had obvious efficacy with less adverse reactions, so it was worth clinical spread.

[Clinical study on effect of total panax notoginseng saponins on immune related inner environment imbalance in rheumatoid arthritis patients].

OBJECTIVE: To study the therapeutic effect and possible mechanism of total panax notoginseng saponins (PNS) for treatment of rheumatoid arthritis (RA), and to observe its safety and influence on RA immune related inner environment. METHODS: Eighty-four patients were randomly assigned to two groups. All were treated with the routine therapy with diclofenac sodium, Leflunomide and prednisone, but for the 43 patients in the treatment group PNS was given additionally. The therapeutic course was 28 days for both groups. Clinical efficacy and change of indexes including platelet counts, immnuoglobulins (IgG, IgA, IgM), complement (C)3, rheumatoid factor (RF), C-reactive protein (CRP), ceruloplasmin (CER), haptoglobin (HPT), and alpha1-acid glycoprotein (AAG) were observed. RESULTS: Significant improvement of clinical symptoms, including the joint swelling index, joint tenderness index, joint pain index, time of morning stiffness and VAS revealed in both groups after treatment, and the effect in the treatment group was better (P<0.05 or P<0.01). PLT, CER, AAG, HPT, CRP, IgG, IgA, IgM, C3 and RF were lowered in both groups (P<0.01), but the lowering in PLT, CER, AAG and CRP in the treatment group was more significant than that in the control group respectively (P < 0.05 or P < 0.01). CONCLUSION: PNS can significantly improve the condition of patients, enhance the therapeutic effect in treating RA, through regulating the disordered immunity and improving the effect of anti-inflammatory and analgesia.
