ABSTRACT

Objective To investigate the effects of whole grain-bean mixed staple food on intestinal microecology,anthropometric,and metabolic parameters of obese people.Methods Totally 87 obese people were divided with random number table into whole grain-bean mixed staple food group (test group) and refined grains staple food group (control group).Body weight (BW),body mass index (BMI),waist circumference (WC),hip circumference (HC),waist/hip ratio (WHR),fasting plasma glucose (FPG),triglyceride (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),and colony count of intestinal flora (bacillus bifidus,lactobacillus,clostridium perfringens,enterobacteria,enterococcus,bacteroides) were measured at baseline and 3 months after intervention.Results Ten people were excluded from this research,6 in the test group and 4 in the control group.Mter 3 months of dietary intervention,BW,BMI,WC,HC,and WHR were significantly lower in the test group than in the control group [(69.45 ± 7.07) kgvs.(72.42 ±5.79) kg,P=0.000; (26.08 ±1.48) kg/m2 vs.(27.27 ±0.81) kg/m2,P=0.000; (82.48±9.30) cm vs.(86.96±4.93) cm,P =0.000; (90.08 ±6.57) cm vs.(92.42 ±6.67) cm,P =0.000; 0.92 ±0.11vs.0.95 ±0.10,P =0.003].The levels of FPG,TC,and LDL-C in the test group were significantly lower than those in the control group [(4.92 ± 0.75) mmoL/L vs.(5.41 ± 1.21) mmoL/L,P=0.037; (3.85±1.13) mmoL/L vs.(4.38 ±1.26) mmoL/L,P=0.046; (3.55 ±1.04) mmoL/L vs.(4.16 ± 1.40) rnmoL/L,P =0.033] ; the level of HDL-C in the test group was significantly higher than that in the control group [(1.13 ± 0.37) mmoL/L vs.(0.92 ± 0.26) mmoL/L,P =0.004].The colony counts of intestinal bacillus bifidus,lactobacillus,and bacteroides in the test group were significantly higher than in the control group [(7.94 ± 0.58) lg CFU/g vs.(6.95 ± 0.38) lg CFU/g,P =0.000 ; (7.67 ± 0.46) lg CFU/g vs.(6.96 ± 0.57) lg CFU/g,P =0.000 ; (5.53 ± 0.44) lg CFU/g vs.(4.80 ±0.23) lg CFU/g,P =0.000],while the colony count of clostridium perfringens was significantly lower than in the control group [(4.40 ± 0.49) lg CFU/g vs.(5.11 ± 0.63) lg CFU/g,P =0.000].Conclusions In obese people,whole grain-bean mixed staple food can improve anthropometric parameters,some lipid metabolic parameters,and intestinal flora.The underlying mechanism may involve promoting the survival and proliferation of probiotics,thereby improving glucose and lipid metabolism.

ABSTRACT

Aim To explore the protective effects of LPPC ( procyanidins extracted from the litchi pericarp) on cardiomyocyte apoptosis in septic rats and its mech-anisms. Methods The rats were randomly divided in-to 5 groups, and were given orally the drug for two weeks continuously. The control group ( control) and sepsis model group ( LPS ) were given distilled water once a day. LPPC low, medium and high dose groups were given LPPC 50 , 100 , 200 mg · kg-1 · d-1 re-spectively which were prepared freshly every day. After the treatment, sepsis animal models were established. Except for the control group, other groups were injec-ted LPS (lipopolysacchride, 10mg·kg-1) intraperito-neally to induce acute sepsis model. 4hrs later, rat se-rum was collected, isoenzyme ( CK-MB ) , lactate de-hydrogenase ( LDH ) and activity of aspertate amin-otransferase ( AST/GOT) were detected. Then rat car-diac tissue was obtained and cardiac tissue malondial-dehyde ( MDA ) , total antioxidant capacity ( T-AOC ) and reduced glutathione ( GSH ) content were deter-mined. TUNEL staining was performed to analyze the apoptosis of myocardial cells. Cleaved caspase-3 and TNF alpha protein expressions were analyzed by West-ern blot. Results Compared with the control group ( control) , serum of sepsis model group rats CK-MB, LDH, AST/GOT and cardiac tissue MDA content were significantly increased (P<0. 01). At the same time, the activity of cardiac tissue T-AOC and GSH de-creased obviously ( P<0. 01 ) . The apoptotic myocar-dial cells increased significantly ( P<0. 01 ) , and the expression level of cleaved caspase-3 and TNF alpha decreased obviously ( P <0. 01 ) . LPPC pretreatment significantly decreased the serum CK-MB, LDH, AST/GOT and tissue MDA content, increased tissue T AOC and GSH activity, attenuated apoptosis of rat myocardi-al cells significantly, and decreased expression level of cleaved caspase-3 and TNF alpha. Conclusion LPPC pretreatment can significantly attenuate rat myocardial cell apoptosis induced by sepsis, and the underlying mechanisms may be related to its anti-oxidative effects.

ABSTRACT

Aim To study the mechanisms of the pro-tective effect of procyanidin B2 ( PCB2 ) on the myocar-dial cell apoptosis induced by lipopolysaccharide ( LPS) . Methods Using the primary culture rat myo-cardial cells, myocardial cell injury model was induced by LPS. PCB2 low, medium and high dose groups, were cultured with 6. 25 , 12. 5 , 25. 0 μmol · L-1 PCB2 respectively in DMEM medium for 24 h continu-ously. Myocardial cell survival rate was determined by MTT colorimetric method. Cardiacmyocyte NOX activi-ty was determined by lucigen chemiluminescence meth-od . Western blot analysis was used to detect myocardi-al NADPH oxidase p47phox expression. TUNEL method was used to detect apoptosis and flow cytometry was used to determine the content of myocardial cells ROS. Results Compared with control group, the cell dam-age induced by LPS group myocardial cell survival rate significantly decreased ( P <0. 01 ) , and myocardial cell NOX activity, p47phox expression, apoptotic cell number and ROS content were significantly increased (P<0. 01). PCB2 low, medium and high dose groups cell survival rates were significantly elevated, myocar-dial cell NOX activity and p47phox expression, apoptotic cell number and the ROS content decreased significant-ly in a dose-dependent manner ( P <0. 01 ) . Conclu-sion PCB2 protects myocardial cell apoptosis induced by LPS via inhibiting the expression of NADPH oxidase activation, p47phox expression and reactive oxygen spe-cies generation.

ABSTRACT

Objective To study the effects of adjusted proportional macronutrient intake on serum uric acid,blood lipids,renal function,and nutritional status of patients with gout and overweight.Methods Sixtyseven patients with gout and overweight were randomized into high protein group and low purine group for 6 months.Each patient had had at least one gouty attacks during the six months before enrollment.Dietary recommendations consisted of calorie restriction to 6276 kJ per day with 40% derived from carbohydrate,30% from protein,and 30% from fat,and the refined carbohydrates were replaced with complex ones and saturated fats with mono-and polyunsaturated ones.High protein group didn't limit purine intake.The two dietary consisted of isoenergetic (6276 kJ).Dietary of low purine group consisted of 60% derived from carbohydrate,10% from protein,and 30% from fat,and limited of parine < 150 mg/d.At onset and 6 months after intervention,fasting blood samples were taken for determination of uric acid(UA),total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),fasting plasma glucose(FBG),serum creatinine(SCr),blood urea nitrogen(BUN),albumin(ALB),total protein(TP),and hemoglobin(Hb);the number of gout attacks was recorded.Results Sixty-one persons completed the study.Dietary measures resulted in weight loss[(65.75 ± 3.26)vs(69.31 ± 7.78)kg,P =0.043)and a decrease in the frequency of sixmonth gout attacks(17 vs 28,P =0.000).After the trial,compared to low-purine group,UA[(420.25 ±36.78)vs(466.81 ±41.97)μmol/L,P=0.000],TC[(5.69±0.46)vs(6.49±1.04)mmol/L,P=0.007),TG[(2.15 ±0.54)vs(3.13 ±0.62)mmol/L,P =0.000]and FBG[(5.63 ±0.82)vs(6.49 ±0.64)mmol/L,P =0.000]decreased significantly in the high protein group.There were no significant differences in LDL-C[(3.55 ±0.80)vs(3.73 ±0.72)mmol/L,P =0.445],SCr[(96.63 ± 16.97)vs(94.28 ±13.35)μmol/L,P =0.597],and BUN[(4.89 ± 1.25)vs(4.46 ± 1.21)mmol/L,P =0.208]between two groups.HDL-C[(1.24±0.22)vs(0.89±0.26)mmol/L,P=0.000],ALB[(41.56±5.37)vs(37.08±5.94)mmol/L,P=0.014],TP(72.97 ±5.41)vs(67.27±7.87)g/L,P=0.005],and Hb[(142.86±12.31)vs(114.25 ± 12.98)g/L,P =0.001]increased significantly in the high protein group.Gouty attacks were reduced and decreased by 48.48% and 22.22% in high protein group and low purine group,respectively.The differences between the two group was statistically significant(P =0.000)Conclusion Change in proportional macronutrient intake is helpful to reduce body weight and thus is beneficial for lowering UA,improving lipid metabolism and nutritional status,and decreasing the frequency of gout attacks.
