Relationship of the preoperative NRS 2002 score,PG-SGA score,and serum indices with postoperative complications in patients with gastric cancer

Objective To examine the utility of the Nutrition Risk Screening 2002(NRS 2002),Patient-Generated Subjective Global Assessment(PG-SGA)and serum factors for the preoperative evaluation of gastric cancer patients.Methods We examined 181 gastric cancer patients treated at the First Affiliated Hospital of Guangxi Medical University from January 2015 to January 2018.Nutritional assessments were administered within 48 h of admission.The body mass index(BMI)and serum factors were measured,and information on preoperative nutritional support and postoperative complications was recorded.Results Both the NRS 2002 and PG-SGA had positive correlations with age(P<0.05),and negative correlations with albumin,prealbumin,transferrin,hemoglobin,BMI,and bodyweight(P<0.05).The NRS 2002 and PG-SGA scores were positively correlated with each other(r=0.683,P<0.01),but had poor consistency(κ=0.357,P<0.01).During the preoperative period,33.2%of patients received nutritional support,mainly enteral nutrition.The nutritional risk group(NRS 2002≥3)received more support than the group without nutritional risk(NRS 2002<3;P<0.05).Patients with nutritional risk or malnutrition who received preoperative nutritional support had fewer postoperative complications than unsupported patients.The overall rate of complications was 12.2%,and the rate of severe complications(gradeⅢor above)was 5.5%.The malnutrition and nutritional risk groups had higher rates of severe complications.Conclusions The combined application of the NRS 2002,PG-SGA,BMI,and serum nutritional indices was useful for the nutritional screening and assessment of preoperative gastric cancer patients.The NRS 2002 and PG-SGA provided guidance on the need for nutritional support during the preoperative period.

Effects of Fermented Puffed Feather Meal on Growth Performance,Serum Biochemical Indices,Meat Quality,and Intestinal Microbiota in Broilers

This study aimed to investigate the effects of fermented puffed feather meal(FPFM)on growth performance,serum biochemical indices,meat quality,and intestinal microbiota in Arbor Acres(AA)broilers.A single-factor design was adopted,and four treatments were administered with five replicates to 240 one-day-old AA broilers.The control group(group A)received a basal diet,while the experimental groups received a basal diet plus 33%(group B),67%(group C)and 100%(group D)FPFM,respectively.Compared with group A,(1)the average daily gain(ADG)in group C decreased(P<0.05),and the feed conversion ratio(FCR)in group D increased(P<0.05);(2)the level of serum urea nitrogen in treatment groups decreased(P<0.05),and the levels of triglyceride,high density lipoprotein,low density lipoprotein,cholesterol,and glucose contents in group D increased(P<0.05)at day 21;(3)the serum immunoglobulin M and immunoglobulin G in group B and the immunoglobulin A in group C increased(P<0.05)at day 21,and the serum immunoglobulin M and immunoglobulin G in group D decreased(P<0.05)at day 42;(4)the share force of breast muscle and thigh muscle in group D increased(P<0.05);(5)the villus height to crypt depth ratio in the jejunum of group B increased(P<0.05)at day 21,and the villus height in group C and D increased(P<0.05)at day 42;(6)the proteobacteria counts in the cecum digesta in treatment groups decreased(P<0.05)at day 21.The basal diet supplemented with 33%FPFM promoted protein metabolism,enhanced immunity and improved meat quality,promoted the digestion and absorption of nutrients,increased intestinal microbial diversity,and improved the content of beneficial bacteria without affecting the growth performance,it was possible to be used as a good substitute for fish meal.

Effect of Dietary Supplementation with Hydrolyzed Wheat Gluten on Growth Performance, Cell Immunity and Serum Biochemical Indices of Weaned Piglets (Sus scrofa)

To investigate the effects of dietary supplementation with hydrolyzed wheat gluten （HWG） on growth performance, cell immunity and serum biochemical indices of weaned piglets, 160 crossed （Large White×andrace） and weaned piglets were randomly divided into 4 treatments with 4 replicates of 10 piglets each. The piglets in each treatment were fed an experimental diet containing either 0 g kg-1 HWG （control group）, 30 g kg-1 HWG （3% HWG group）, 50 g kg-1 HWG （5% HWG group）, or 2.5 g kg-1 glycyl-L-glutamine （0.25% Gly-Gln group）. The results showed that the diarrhea rates in 3% HWG and 5% HWG groups were significantly lower than in control group from d 1 to 14 （P〈0.05）, while the average daily gain （ADG） in each of two groups was increased （P〉0.05）. When compared with control group, dietary supplementation with 3% HWG increased the ratio of CD4＋：CD8＋ and the ratio of serum albumin and globulin concentrations （A：G） on d 14 and 28, as well as the proliferation of T- and B-lymphocytes （P〉0.05） on d 28. In addition, on d 14 and 28, the A：G ratio in 5% HWG group was significantly higher than in control group （P〈0.05）, while the ratio of CD4＋：CD8＋ increased slightly （P〉0.05）. Interestingly, 0.25% Gly-Gln group had higher proportion of CD3＋ （P〉0.05） and CD4＋ （P〈0.05） on d 14 than control group, but growth performances of 0.25% Gly-Gln group were negatively affected at all experiment stages. These results suggested that HWG might improve the growth performance of piglets by strengthening cell immunity and decreasing the occurrence of diarrhea during the prophase after weaning.

Study on Growth,Serum Biochemical and Antioxidant Enzyme Indices of Juvenile Siganus guttatus Fed with Enteromorpha prolifra and Artificial Feed

In order to provide reference for using Sigartus guttatus to control overgrowth of Ertteromorpha prolifra, the growth, serum biochemical and antioxidant enzyme indices of juvenile S. guttatus respectively fed with E. prolifra and artificial feed were studied. One hundred and eighty individuals were cultivated for 90 days in six 2.5 m × 1.5 m × 1.5 m cages （30 ind. per cage） which mesh size were 0.5 mm. The experimental animals were divided into two dietary groups （ three cages for each group） that were fed with E. prolifra and artificial feed respectively. During the culture period, temperatures ranged from 23.0 to 26.5℃, pH was between 7.8 and 8.2, dissolved oxygen was more than 5.0 mg/L. The weight gain rate, specific growth rate, relative growth rate, hepato-somatic index of juvenile S. guttatus fed with E. prolifra were significantly lowe than that fed with artificial feed （P 〈 0.05）. The total protein （TP）, urea nitrogen （UN） and alkaline phosphatase （AKP） of juvenile S. guttatus fed with E. Prolifra were significantly higher than that fed with artificial feed （P 〈0.05）, while glutamic oxalacetie transaminase （AST/GOT） and glutamic-pyruvic transaminase （ALT/GPT） of juvenile S. guttatus fed with E. prolifra were significantly lower than that fed with artificial feed （P 〈 0.05 ）. SOD, GPX and anti-superoxide anion radical activity in liver, kidney, gill and muscle of juvenile S. guttatus fed with E. prolifra were higher than that fed with artificial feed, and these antioxidant enzyme activities in kidney of juvenile S. gtatatus fed with E. prolifra was significantly higher than that fed with artificial feed （P 〈 0.05）, while CAT and hydroxyl radical-inhibiting activity in liver of juvenile S. guttatus fed with arti- ficial feed were significantly higher than that fed with E. prolifra （P 〈 0.05 ）. Juvenile S. guttatus fed with E. prolifra showed poor growth performance but better antioxidant defense system. S. guttatus is easily raised and has stronger ability of digestion and absorption of E. Prolifra. The technique that uses S. gtatatus to control E. prolifra deserves deeply study.

Evaluating the clinical application and effect of acupuncture therapy in anal function rehabilitation after low-tension rectal cancer surgery

BACKGROUND According to the indexes of serum and anal function,acupuncture therapy was applied to patients with low rectal cancer in order to avoid the occurrence of anal incontinence and reduce complications.AIM To explore the clinical application and evaluate the effect of acupuncture therapy for anal function rehabilitation after low-tension rectal cancer surgery.METHODS From the anorectal surgery cases,we selected 120 patients who underwent colorectal cancer surgery between January 2020 and December 2022 and randomly divided them into a control group(n=60),observation group(n=60),and control group after surgery for lifestyle intervention(including smoking cessation and exercise),dietary factor adjustment,anal movement,and oral loperamide treatment.The serum levels of motilin,5-hydroxytryptamine,and vasoactive intestinal peptide(VIP),Wexner score for anal incontinence,and incidence of complications were compared between groups.RESULTS After treatment,the VIP and 5-hydroxytryptamine levels in the observation group were lower than those in the control group(P<0.05).The motilin level was higher than that in the control group(P<0.05).Postoperative anal incontinence was better in the observation group than in the control group(P<0.05).The incidence of complications in the observation group was 6.67%,which was significantly lower than that in the control group(21.67%;P<0.05).CONCLUSION Acupuncture therapy has a positive effect on the rehabilitation of anal function after low-tension rectal cancer surgery;it can effectively help to improve the serum indices of patients,avoid the occurrence of anal incontinence,and reduce the incidence of complications.Popularizing and applying it will be valuable.

Ameliorating effects of Raphanus sativus leaves on sodium arsenite-induced perturbation of blood indices in Swiss albino mice

Objective: To evaluate the ameliorating effects of Raphanus sativus leaves(RSL)against sodium arsenite(Sa)-induced adverse effects through mice experiments.Methods: Swiss albino mice were divided into four equal groups: control, Sa, RSL,RSL + Sa. Sa(10 mg/kg body weight/day), and powder form of RSL(50 mg/kg body weight/day) were provided as food supplement orallty. Blood indices were measured using commercially available kits through colorimetric methods.Results: It was observed that lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase activities were significantly(P < 0.05)higher in Sa-treated mice than those in the control group. RSL significantly reduced Sainduced elevation of the activities of these enzymes in serum significantly(P < 0.05).Serum butyrylcholinesterase activity and high density lipoproteins cholesterol levels in Satreated mice were significantly(P < 0.05) lower than the control group, and the food supplementation of RSL could significantly(P < 0.05) prevent the reduction of Sa-mediated serum butyryl cholinesterase activity and high density lipoproteins cholesterol levels. RSL could also reduce the Sa-induced elevation of serum urea level significantly(P < 0.05).Conclusions: Results of this study suggest the protective or ameliorating effects of RSL on Sa-induced perturbation of blood indices are related to the hepatic, cardiovascular and kidney dysfunction. Therefore, RSL may be useful to reduce arsenic toxicity in human in the future.

[Conclusion]Additives of traditional Chinese medicines have an ac- tive effect on blood biochemical indices of Wenchang chickens.

Biochemical and Oxidative Stress Parameters of Broilers Fed Meal and Protein Isolate of <i>Mucuna pruriens</i>Seeds

Mucuna pruriens (velvet bean) represents an interesting source of protein poorly studied. The effect of dietary inclusion of meal and protein isolate of Mucuna seeds on biochemical and oxidative stress parameter of broilers (135-one-day Cobb500 chickens) was investigated. Three isonitrogenous diets were formulated from soya bean meal (Control group: RTS), Mucuna meal (coded RFM) and Mucuna protein isolate (coded RIM). Each of the dietary treatments was triplicated with 15 birds per replicate in a completely randomized design. The birds were offered feed and water ad libitum. The results revealed significant (p < 0.05) effect of N source on the organ total proteins with treatment RFM and RIM exhibiting lower but comparable levels in the Liver (2.01 and 1.98 g/dL), Heart (1.95 and 1.89 g/dL) and Kidney (1.92 and 1.91 g/dL). Triglycerides contents were significantly (p < 0.05) higher in the liver of broilers fed RIM and RFM (2.49 and 2.36 mg/dL), in the Kidney of chicks fed RIM and RTS (2.27 and 2.34 mg/dL) and in the Heart of birds fed RTS and RFM (1.90 and 1.87 mg/dL). Broilers fed RFM presented the highest (p < 0.05) Liver total cholesterol (1.61 mg/dL) and ALAT contents but with similar values with birds fed RTS (36.43 and 35.50 UI/L respectively). ASAT level was significantly high (p < 0.05) in the Liver and Plasma (265.50 and 264.50 UI/L respectively) of broilers of RFM diet. In all the organs, MDA content was highest (p < 0.05) in chicks of RIM batch. In the Heart and Plasma, chicks of RFM (3.23 and 5.05 μl/mg respectively) and RIM (5.45 and 5.35 μl/mg respectively) diets registered elevated rate of CAT. In view of these results, investigations remain to be carried out on the impact of the inclusion of meal and protein isolate of M. pruriens seeds in broiler’s diet during the growth-finishing phase.

Effects of dietary arginine levels on growth performance,body composition, serum biochemical indices and resistance ability against ammonia-nitrogen stress in juvenile yellow catfish(Pelteobagrus fulvidraco)

This experiment was conducted to investigate the effects of dietary arginine levels on growth performance, body composition, serum biochemical indices and resistance ability against ammonia-nitrogen stress in juvenile yellow catfish(Pelteobagrus fulvidraco). Five isonitrogenous and isolipidic diets(42%protein and 9% lipid) were formulated to contain graded levels of arginine(2.44%, 2.64%, 2.81%, 3.01% and3.23% of diet), by supplementing L-Arginine HCI. Seven hundred juvenile yellow catfish with an initial average body weight of 1.13 ± 0.02 g were randomly divided into 5 groups with 4 replicates of 35 fish each and each group was fed one of the diets. After 56 d feeding, fish were exposed to 100 mg/L of ammonia-nitrogen for 72 h. The results showed that weight gain(WG) and specific growth rate(SGR) in2.64% and 2.81% groups were significantly higher than those in 3.23% group(P < 0.05). The feed conversation ratio(FCR) in 2,64%, 2,81% and 3.01% groups was significantly decreased when compared with3,23% group. The protein efficiency ratio(PER) in 2.64% group was significantly higher than that in 2.44%and 3.23% groups(P < 0.05). The condition factor(CF) of fish was significantly higher in 2.81% group than that in 2,44% group(P < 0.05). Dietary arginine levels had no significant effect on hepatosomatic index(HSI), viscerosomatic index(VSI), and whole-body dry matter, crude protein, crude lipid, ash contents, as well as serum total protein(TP), triglyceride(TG), glucose(GLU), urea nitrogen(UN) contents and aspartate aminotransferase(AST), alanine aminotransferase(ALT) activities(P> 0.05). After the fish were challenged to ammonia-nitrogen for 72 h, their cumulative mortality rate in 2.81% group was significantly lower than that in 2.44% group(P < 0.05). The results suggested that dietary arginine level at 2.81%could optimize anti-ammonia-nitrogen stress ability of juvenile yellow catfish and a level of 3.23%arginine seemed to depress the growth performance of fish and decreased their tolerance to the ammonia-nitrogen stress under current study. A quadratic regression analysis based on WG indicated that the optimal dietary arginine requirement of juvenile yellow catfish was estimated to be 2.74% of the diet(6.45% of dietary protein) under current culture conditions.

Determination of serum fibrosis indexes in patients with chronic hepatitis and its significance

Objectives To study the relationship between serum levels of hyaluronic acid (HA), type Ⅲ procollagen (PCⅢ), laminin (LN), type Ⅳ collagen (Ⅳ-C) and hepatic fibrosis and to determine their value in clinical practice. Methods 2600 serum samples from chronic hepatitis patients were assayed for fibrosis indexes including HA, PCⅢ, LN and Ⅳ-C with RIA. Liver biopsy was performed in 280 of those patients and the biopsy material was examined histopathologically. The inflammation grade of the liver, stage of fibrosis and degree of chronic hepatitis were recorded and were compared with fibrotic indexes. Results Among 2600 chronic hepatitis patients, every fibrotic index had a significant correlation with the inflammation grade, fibrosis staging and the degree of chronic hepatitis (P<0.01). The coefficient correlation of the results of histopathological examinations to HA was 0.544, 0.548 and 0.468 respectively, that to PCⅢ, 0.495, 0.424 and 0.335, that to LN, 0.214, 0.204 and 0.184, and that to Ⅳ-C, 0.406, 0.404 and 0.412, respectively. Conclusions Serum fibrosis indexes are fairly well correlated with the inflammation grade of the liver, fibrosis staging and the degree of chronic hepatitis. However, as diagnostic markers, they should be considered in combination with liver function tests, ultrasonography and clinical manifestations.

Effects of dietary methionine supplementation on growth performance of cubs,nutrient digestibility, nitrogen metabolism and serum biochemical indicators of female blue foxes(Alopex lagopus)

The objective of the present study was to investigate the effects of methionine(Met) supplementation on growth performance of cubs, nutrient digestibility, nitrogen metabolism and serum biochemical parameters of female blue foxes. One hundred primiparous female blue foxes that were similar in breeding date, pedigree, age, and weight were selected for the trial. The foxes were randomly assigned to four groups(n = 25 each group) and fed diets supplemented with Met at 2(Met2), 4(Met4), 6(Met6)and 8 g/kg(Met8), respectively, for 40 days. Our data showed that body weights at 20 and 40 d were significantly higher in the Met4 group than in the Met2 group(P < 0.05). The Met4 group also had the highest apparent digestibility of dry matter and crude protein compared with either the Met2, Met6, or Met8 group(P< 0.05). The serum Met and isoleucine(Ile) concentrations were significantly higher in the Met4 group than in the Met6 or Met8 group(P < 0.05). In summary, these data indicate that supplementary Met improves growth performance of cubs likely due to increased crude protein and dry matter and increased nitrogen retention of female blue foxes. The optimal amount of Met supplementation is10 g/kg basal diet.
