Study on the occurrence and influencing factors of gastrointestinal symptoms in hemodialysis patients with uremia

BACKGROUND Gastrointestinal symptoms are common in patients with uremia undergoing hemodialysis,and these symptoms seriously affect patients'prognosis.AIM To assess the occurrence and factors influencing gastrointestinal symptoms in patients with uremia undergoing hemodialysis.METHODS We retrospectively selected 98 patients with uremia who underwent regular hemo-dialysis treatment in the blood purification center of our hospital from December 2022 to December 2023.The gastrointestinal symptoms and scores of each dimension were evaluated using the Gastrointestinal Symptom Grading Scale(GSRS).Patients were divided into gastrointestinal symptoms and no gastrointestinal symptom groups according to whether they had gastrointestinal symptoms.The factors that may affect gastrointestinal symptoms were identified by single-factor analysis.Multiple logistic regression analysis was performed to identify independent risk factors for gastrointestinal symptoms.RESULTS Gastrointestinal symptoms included indigestion,constipation,reflux,diarrhea,abdominal pain,and eating disorders,and the total average GSRS score was 1.35±0.47.This study showed that age,number of tablets,dialysis time,glucocorticoid,parathyroid hormone(PTH),combined diabetes mellitus and C-reactive protein(CRP)were independent risk factors for gastrointestinal symptoms in patients with uremia undergoing hemodialysis,whereas body mass index(BMI),hemoglobin(Hb),and urea clearance index were independent protective factors(P<0.05).CONCLUSION Gastrointestinal symptoms are mostly mild in patients with uremia undergoing hemodialysis,most commonly including dyspepsia,eating disorders,and gastroesophageal reflux.The independent influencing factors mainly include the BMI,age,number of pills taken,dialysis time,urea clearance index,Hb,use of glucocorticoids,and thyroid hormone level.PTH,CRP,and diabetes are clinically related factors influencing the occurrence of gastrointestinal symptoms,and targeted prevention can be performed.

Age,blood tests and comorbidities and AIMS65 risk scores outperform Glasgow-Blatchford and pre-endoscopic Rockall score in patients with upper gastrointestinal bleeding

BACKGROUND Upper gastrointestinal(GI)bleeding is a life-threatening condition with high mortality rates.AIM To compare the performance of pre-endoscopic risk scores in predicting the following primary outcomes:In-hospital mortality,intervention(endoscopic or surgical)and length of admission(≥7 d).METHODS We performed a retrospective analysis of 363 patients presenting with upper GI bleeding from December 2020 to January 2021.We calculated and compared the area under the receiver operating characteristics curves(AUROCs)of Glasgow-Blatchford score(GBS),pre-endoscopic Rockall score(PERS),albumin,international normalized ratio,altered mental status,systolic blood pressure,age older than 65(AIMS65)and age,blood tests and comorbidities(ABC),including their optimal cut-off in variceal and non-variceal upper GI bleeding cohorts.We subsequently analyzed through a logistic binary regression model,if addition of lactate increased the score performance.RESULTS All scores had discriminative ability in predicting in-hospital mortality irrespective of study group.AIMS65 score had the best performance in the variceal bleeding group(AUROC=0.772;P<0.001),and ABC score(AUROC=0.775;P<0.001)in the non-variceal bleeding group.However,ABC score,at a cut-off value of 5.5,was the best predictor(AUROC=0.770,P=0.001)of inhospital mortality in both populations.PERS score was a good predictor for endoscopic treatment(AUC=0.604;P=0.046)in the variceal population,while GBS score,(AUROC=0.722;P=0.024),outperformed the other scores in predicting surgical intervention.Addition of lactate to AIMS65 score,increases by 5-fold the probability of in-hospital mortality(P<0.05)and by 12-fold if added to GBS score(P<0.003).No score proved to be a good predictor for length of admission.CONCLUSION ABC score is the most accurate in predicting in-hospital mortality in both mixed and non-variceal bleeding population.PERS and GBS should be used to determine need for endoscopic and surgical intervention,respectively.Lactate can be used as an additional tool to risk scores for predicting inhospital mortality.

Immune function, gastrointestinal hormone levels, and their clinical significance in patients with gastric ulcers complicated with depression

BACKGROUND Gastric ulcer(GU)is a common digestive tract disease,and medical records of GU combined with depression are increasingly common.Currently,the risk factors and pathogenesis of GU complicated with depression remain unclear.Low immune function and gastrointestinal hormone levels may also be significant risk factors.Therefore,this study explored the immune function and gastrointestinal hormone levels in patients with GU combined with depression.AIM To explore the immune function,gastrointestinal hormone level,and clinical significance of patients with GU combined with depression.METHODS A retrospective analysis was conducted on 300 patients with GU combined with depression admitted to Guizhou Provincial People’s Hospital from January 2021 to June 2022 as the study subjects.According to the Hamilton Depression Scale(HAMD)score,patients were divided into mild-to-moderate(n=210)and heavy(n=90)groups.Basic data,immune function indices[immunoglobulin A(IgA),IgM,IgG,serum CD4+and CD8+percentage,and CD4+/CD8+ratio],and gastrointestinal hormone indices[serum gastrin(GAS),cholecystokinin(CCK),and motilin(MTL)levels]were collected.The basic data of the two groups were compared,and the immune function and gastrointestinal hormone indices were analyzed.Multivariate logistic regression was used to analyze the factors influencing the severity of GU complicated with depression.The receiver operating characteristic(ROC)curve and area under the ROC curve(AUC)were used to analyze the value of the immune function index,gastrointestinal hormone index,and combined index in predicting the severity of GU complicated with depression.RESULTS There were no marked differences in sex,age,body mass index,abdominal distension,abdominal pain,belching,nausea,vomiting,or sleep disorders between the heavy and mild-to-moderate groups(P>0.05).There was a marked difference in the family history of depression between the heavy and mild-to-moderate groups(P<0.05).There were significant differences in serum IgA and IgM levels and serum CD4+,CD8+,and CD4+/CD8+ratios between the heavy and mild-to-moderate groups(P<0.05).Multivariate analysis showed that IgA,IgM,GAS,and CCK serum levels influenced the severity of GU with depression(P<0.05).The AUC of the ROC curve for serum IgA level predicting GU with depression severity was 0.808[95%confidence interval(CI):0.760-0.857],the AUC of the serum IgM level was 0.757(95%CI:0.700-0.814),the AUC of the serum GAS level was 0.853(95%CI:0.810-0.897),the AUC of the serum CCK level was 0.762(95%CI:0.709-0.822),the AUC of immune function(IgA,IgM)and gastrointestinal hormone levels(GAS,CCK)for the prediction of GU with depression severity was 0.958(95%CI:0.933-0.976).CONCLUSION Important factors influencing GU complicated with depression are serum IgA,IgM,GAS,and CCK indicators.They can be used as indicators to predict the severity of GU complicated with depression.

Rikkunshito increases appetite by enhancing gastrointestinal and incretin hormone levels in patients who underwent pyloruspreserving pancreaticoduodenectomy: A retrospective study

BACKGROUND Rikkunshito(TJ-43)relieves gastrointestinal disturbance by increases in the levels of acylated ghrelin.AIM To investigate the effects of TJ-43 in patients undergoing pancreatic surgery.METHODS Forty-one patients undergoing pylorus-preserving pancreaticoduodenectomy(PpPD)were divided into two groups;patients took daily doses of TJ-43 after surgery or after postoperative day(POD)21.The plasma levels of acylated and desacylated ghrelin,cholecystokinin(CCK),peptide YY(PYY),gastric inhibitory peptide(GIP),and active glucagon-like peptide(GLP)-1 were evaluated.Oral calorie intake was assessed at POD 21 in both groups.The primary endpoint of this study was the total food intake after PpPD.RESULTS The levels of acylated ghrelin were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 administration at POD 21,and oral intake was significantly increased in patients treated with TJ-43.The CCK and PYY levels were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 treatment.Furthermore,the GIP and active GLP-1 levels increased and values at POD 21 were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 administration.Insulin secretion tended to increase in patients treated with TJ-43.CONCLUSION TJ-43 may have advantages for oral food intake in patients in the early phase after pancreatic surgery.Further investigation is needed to clarify the effects of TJ-43 on incretin hormones.

Gastric emptying and plasma levels of gastrointestinal hormones in patients with peptic ulcer

IM To study the plasma level of gastrointestinal hormones and gastric emptying in patients with peptic ulcer. METHODS Thirty patients with gastric ulcer (GU), and 29 duodenal ulcer (DU) and 12 controls were studied. Plasma levels of SS, VIP and SP were measured by radioimmunoassay, and gastric emptying half time (GET1/2) was determined with TC99mresin solid meal method. RESULTS GET1/2(min) was significantly longer in GU than that in controls (659±148 vs 533±43, P<001) and plasma VIP levels (ng/L) were significantly higher than in controls (375±107 vs 184±59, P<005). There was a significant positive correlation between GET1/2 and plasma VIP levels (r=055,P<001). No significant changes were found in SS and SP in GU compared with controls (P>005). GET1/2 in DU was markedly shorter than the control group (417±102 vs 533±43, P<001), and plasma SS levels (ng/L) significantly lower than those in controls (64±25 vs 119±34,P<001), there was a significant positive correlation between GET1/2 and SS levels (r=056,P<001). Plasma SP levels (ng/L) in DU were significantly higher than the controls (544±127 vs 416±58,P<001),there was a significant negative correlation between GET1/2 and SP levels (r=-068,P<001). No significant difference was found in the plasma VIP levels between DU and controls (P>005).CONCLUSION VIP elevation may contribute to the GET1/2 delay and the occurrence of GU. The increased SP and lowered SS may play important roles in the GET1/2 acceleration and the pathogensis of DU.

Role of sex hormones in gastrointestinal motility in pregnant and non-pregnant rats

AIM: To correlate gastric contractility, gastrointestinal transit, and hormone levels in non-pregnant(estrous cycle) and pregnant rats using noninvasive techniques. METHODS: Female rats(n = 23) were randomly divided into(1) non-pregnant,(contractility, n =6; transit, n = 6); and(2) pregnant(contractility, n = 5; transit, n = 6). In each estrous cycle phase or at 0, 7, 14, and 20 d after the confirmation of pregnancy, gastrointestinal transit was recorded by AC biosusceptometry(ACB), and gastric contractility was recorded by ACB and electromyography. After each recording, blood samples were obtained for progesterone and estradiol determination. RESULTS: In the estrous cycle, despite fluctuations of sex hormone levels, no significant changes in gastrointestinal motility were observed. Days 7 and 14 of pregnancy were characterized by significant changes in the frequency of contractions(3.90 ± 0.42 cpm and 3.60 ± 0.36 cpm vs 4.33 ± 0.25 cpm) and gastric emptying(168 ± 17 min and 165 ± 15 min vs 113 ± 15 min) compared with day 0. On these same days, progesterone levels significantly increased compared with control(54.23 ± 15.14 ng/m L and 129.96 ± 30.52 ng/mL vs 13.25 ± 6.31 ng/mL). On day 14, we observed the highest level of progesterone and the lowest level of estradiol compared with day 0(44.3 ± 15.18 pg/mL vs 24.96 ± 5.96 pg/mL). CONCLUSION: Gastrointestinal motility was unaffected by the estrous cycle. In our data, high progesterone and low estradiol levels can be associated with decreased contraction frequency and slow gastric emptying.

Effects of Xiangsha Liujunzi decoction drug serum on gastric antrum smooth muscle cells from rats with functional dyspepsia by regulating gastrointestinal hormones

Objective:To observe the effect and mechanism of Xiangsha Liujunzi decoction(XSLJZD)drug serum on gastric antrum smooth muscle cells(SMCs)in rats with functional dyspepsia(FD).Methods:Gastric antrum SMCs from rats with FD were isolated,cultured,and then divided into six groups as follows:control,model,domperidone,low-dose XSLJZD(LXSLJZD),medium-dose XSLJZD(MXSLJZD),and high-dose XSLJZD(HXSLJZD).Each group was administered the corresponding drug serum for intervention.Drug serum intervention conditions and proliferative activity of SMCs were tested by cholecystokinin octapeptide.Ghrelin,gastrin,somatostatin,and substance P(SP)levels were measured by ELISA.Somatostatin and SP mRNA expression was measured by real-time PCR.Results:A concentration of 10%drug serum for 24 h was decided to be the best intervention condition for later study.The mean optical density value in the model group was lower than that in the control group(P紏.001).Optical density values in the domperidone and HXSLJZD groups were higher than those in the model group(P?.025,P?.032,respectively).Gastrin,SP,and ghrelin levels in the model group were lower(P?.007,P?.037,P?.005,respectively),but somatostatin levels were higher,compared with those in the control group(P?.031).Gastrin,SP,and ghrelin levels in the domperidone,MXSLJZD,and HXSLJZD groups were higher than those in the model group(all P<.05).Somatostatin levels in the four drug-treated groups were lower than those in the model group(P?.002,P?.007,P?.001,P?.009,respectively).SP mRNA levels in the model group were lower than those in the control,domperidone,MXSLJZD,and HXSLJZD groups(P?.037 P?.016,P?.025,P?.002,respectively).Somatostatin mRNA levels in the model group were higher than those in the control and MXSLJZD groups(P紏.042,P紏.035).Conclusions:XSLJZD and domperidone drug serum effectively promote proliferative activity of gastric antrum SMCs in an FD model.The mechanism of this activity may be regulated by gastrointestinal hormones.

Effect of explosive noise on gastrointestinal transit and plasma levels of polypeptide hormones

AIM： To investigate the effect of firing noise on gastrointestinal transit and probe its mechanism by measuring the levels of plasma polypeptide hormones. METHODS： A total of 64 SD rats were randomly divided into a control group and three stimulating groups. Firing noise of different intensity by sub-machine guns was used as inflicting factor. The effect of firing noise on liquid substance gastrointestinal transit and solid substance gastrointestinal transit was observed by measuring the ratio of carbon powder suspension transmitting and barium sticks transmitting respectively. Plasma levels of polypeptide hormones were measured by radio-immunoassay. RESULTS： The noise accelerated gastrointestinal transit of solid food by more than 80 db;and accelerated gastrointestinal transit of liquid food significantly by more than 120 db. Meantime, plasma levels of plasma motilin （MTL）（157.47±16.08; 151.90±17.08）, somatostatin （SS）（513.97±88.77; 458.25±104.30）, substance P （SP）（115.52±20.70; 110.28±19.96） and vasoactive intestinal peptide （VIP） （214.21±63.17; 251.76±97.24） remarkably changed also. CONCLUSION： Within a certain intensity range, the firing noise changes the levels of rat plasma gastrointestinal hormones, but the gastrointestinal transit is still normal. Beyond the range, the noise induces plasma hormone levels disturbance and gastrointestinal transit disorder. ~

Objective:To investigate the effect of intestinal flora from Henoch-Schönlein purpura(HSP)on visceral sensitivity,gastrointestinal hormones and cytokines in pseudo-sterile rats.Methods:The pseudo-sterile rat model was established.The rats were was given fecal microbiota solutions of children with abdominal HSP and healthy children,respectively.The visceral sensitivity was determined by abdominal withdrawal reflex(AWR)which was induced by rectal balloon distention in all the rats.And serum gastrin(Gas),motilin(MTL),cholecystokinin(CCK),substance P(SP),tumor necrosis factor(TNF)-αand interleukin(IL)-6 levels in rats were measured with ELISA method.Results:The volume of rectum water injection under the score 3 of AWR in the rats administrated with fecal microbiota solution from HSP children(HSP group)was significantly decreased compared with that in the rats administrated with fecal microbiota solution from healthy children(HC group),and there was significant difference between these two groups(P<0.05).The serum Gas,MTL,CCK and SP levels were higher in HSP group than those in HC group.And serum MTL,CCK and SP levels in HSP group were significantly different from those in the HC group.The serum TNF-αandIL-6 levels were higher in HSP group than those in HC group,there was significant difference between these two groups(P<0.05).Conclusion:Intestinal flora from HSP can induce the production of visceral sensitivity,inhibit gastrointestinal hormone secretion and prompt cytokine production.

Correlation between serum CGRP and gastrointestinal hormones, inflammatory response in patients with reflux esophagitis

Objective:To detect serum content of calcitonin gene-related peptide (CGRP) in patients with reflux esophagitis (RE), evaluate the relationship between CGRP and gastrointestinal hormones, inflammatory response.Methods: 119 cases of RE patients diagnosed in our hospital during August 2015 to March 2018 were divided into stage I-II RE group (n=72) and stage III-IV RE group (n=47) according to Savary-Miller criteria, 100 cases of healthy volunteers underwent routine gastroenteroscopy at the same time were selected as Normal control group. Serum content of CGRP, gastrointestinal hormones and inflammatory response indexes were measured and their correlations were evaluated.Results: Serum content of CGRP in stage I-II RE group, stage III-IV RE group were higher than those in Normal control group;contents of GAS and MTL in stage I-II RE group, stage III-IV RE group were lower than those in Normal control group, contents of VIP and SS were higher than those in Normal control group;contents of inflammatory reaction indexes such as IL-4, IL-17, IL-23 and IFN-γwere higher than those in Normal control group (P<0.05). Along with aggravation of RE, above indexes increased significantly (P<0.05). Correlation analysis showed that, serum content of CGRP in RE patients were directly related to the levels of gastrointestinal hormones and inflammatory markers (P<0.05).Conclusion: Expression of CGRP in RE patients is abnormally high, and the specific content is directly related to the degree of gastrointestinal hormone secretion disorder and systemic inflammatory reaction, which is of great significance to the auxiliary evaluation of RE.

Effect of minimally invasive surgery under anus and colonoscopy on pain stress, gastrointestinal hormones and vascular endothelial function in patients with rectal cancer

Objective: To discuss the effects of minimally invasive surgery under transrectal anoscope on pain stress, gastrointestinal hormones and vascular endothelial function in patients with rectal cancer. Methods Totally 64 patients with rectal cancer who underwent minimally invasive surgery under transanal anastomosis from January 2017 to December 2018 in our hospital were selected as the observation group and the retrospective analysis of clinical data was conducted. Another 64 patients who underwent traditional laparotomy at the same time in our hospital were selected as the control group. Pain stress, gastrointestinal hormones, vascular endothelial function, and tumor marker changes were compared between the two groups. Results There were no significant differences in pain stress index, gastrointestinal hormone, vascular endothelial function index and tumor marker level between the two groups before operation (P>0.05). After operation, the levels of SP, BK and PGE2 in the two groups were higher than those before surgery (P<0.05), and the levels of GAS, MTL, VIP, VEGF, MMP-9, ET-1, CEA, CA724, CA125 and CA19-9 were higher with preoperative reduction of P<0.05. The levels of SP, BK, PGE2, VEGF, MMP-9, ET-1, CEA, CA724, CA125 and CA19-9 in the observation group after operation were lower than those in the control group (P<0.05), and the GAS, MTL and VIP levels were significantly higher than the control group (P<0.05). Conclusion Minimally invasive surgery under transanal anoscope can reduce the pain stress of patients with rectal cancer, and the influence of gastrointestinal hormones is slight. It can effectively reduce the vascular endothelial function index and tumor marker level, help the immune function recovery of patients, and promote postoperative rehabilitation of patients.

INTRODUCTIONHelicobacter pylori(Hp)infection is closely relatedto gastrointestinal hormones and involves theformation of gastritis,gastric carcinoma and pepticulcer.Its pathogenesis relevant

Gastrointestinal hormone abnormalities and G and D cells in functional dyspepsia patients with gastric dysmotility

AIM: To investigate the relationship between gastric dysmotility,gastrointestinal hormone abnormalities, and neuroendocrine cells in gastrointestinal mucosa in patients with functional dyspepsia (FD).METHODS: Gastric emptying was assessed with solid radiopaque markers in 54 FD patients, and the patients were divided into two groups according to the results, one with delayed gastric emptying and the other with normal gastric emptying. Seventeen healthy volunteers acted as normal controls. Fasting and postprandial plasma levels and gastroduodenal mucosal levels of gastrointestinal hormones gastrin, somatostatin (SS) and neurotensin (NT)were measured by radioimmunoassay in all the subjects.G cells (gastrin-producing cells) and D cells (SS-producing cells) in gastric antral mucosa were immunostained with rabbit anti-gastrin polyclonal antibody and rabbit anti-SS polyclonal antibody, respectively, and analyzed quantitatively by computerized image analysis.RESULTS: The postprandial plasma gastrin levels, the fasting and postprandial plasma levels and the gastric and duodenal mucosal levels of NT were significantly higher in the FD patients with delayed gastric emptying than in those with normal gastric emptying and normal controls. The number and gray value of G and D cells and the G cell/D cell number ratio did not differ significantly between normal controls and the FD patients with or without delayed gastric emptying.CONCLUSION: Our findings suggest that the abnormalities of gastrin and NT may play a role in the pathophysiology of gastric dysmotility in FD patients, and the abnormality of postprandial plasma gastrin levels in FD patients with delayed gastric emptying is not related to the changes both in the number and gray value of G cells and in the G cell/D cell number ratio in gastric antral mucosa.

Efficacy of ankaferd blood stopper application on nonvariceal upper gastrointestinal bleeding

AIM:To prospectively assess the hemostatic efficacy of the endoscopic topical use of ankaferd blood stopper(ABS) in active non-variceal upper gastrointestinal system(GIS) bleeding.METHODS:Endoscopy was performed on 220 patients under suspiciency of GIS bleeding.Patients with active non-variceal upper gastrointestinal bleeding(NVUGIB) with a spurting or oozing type were included.Firstly,8-10 cc of isotonic saline was sprayed to bleeding lesions.Then,8 cc of ABS was applied on lesions in which bleeding continued after isotonic saline application.The other endoscopic therapeutic methods were applied on the lesions in which the bleeding did not stop after ABS.RESULTS:Twenty-seven patients had an active NVUGIB with a spurting or oozing type and 193 patients were excluded from the study since they did not have non-variceal active bleeding.8 cc of ABS was sprayed on to the lesions of 26 patients whose bleeding continued after isotonic saline and in 19 of them,bleeding stopped after ABS.Other endoscopic treatment methods were applied to the remaining patients and the bleeding was stopped with these interventions in 6 of 7 patients.CONCLUSION:ABS is an effective method on NVUGIB,particularly on young patients with no coagulopathy.ABS may be considered as part of a combination treatment with other endoscopic methods.

The effect of the ratio of standardized ileal digestible lysine to metabolizable energy on growth performance,blood metabolites and hormones of lactating sows

A total of 335 lactating sows （Landrace x Large White） were used in two experiments to determine the optimum ratio of standardized ileal digestible lysine （SID-Lys） to metabolizable energy （ME） for mixed parity sows during lactation. In Exp. 1, 185 sows （weighing an average of 256.2 ± 6.5 kg and having an average parity of 3.4 ± 0.3） were allocated to one of six experimental diets in a completely randomized block design within parity groups （1, 2, and 3＋）. The experimental diets were formulated to contain 3.06, 3.16, 3.20, 3.25, 3.30 or 3.40 Mcal/kg of ME and each diet was fed to the sows throughout a 28 day lactation. All diets provided a similar SID-lysine level （0.86%）. As a result, the diets provided a SID-Lys：ME ratio of 2.81, 2.72, 2.69, 2.65, 2.61 or 2.53 g/Mcal ME. Sow feed intake was significantly （P 〈 0.01） affected by the energy content of the diet as well as by sow parity. Using regression analysis, feed intake was shown to be maximized at 3.25, 3.21, 3.21 and 3.21 Mcal/kg of ME for parity 1, 2, 3＋ sows and the entire cohort of sows respectively （quadratic; P 〈 0.01）. In addition, the result of feed intake can be expressed as 2.65, 2.69, 2.69 and 2.68 g/Mcal based on analysis of SID-Lys：ME ratio. Litter weight gain was affected by dietary treatment for parity 3＋ sows and the entire cohort （P 〈 0.01）. Based on regression analysis, litter weight gain was maximized at 3.25 and 3.24 Mcal/kg of ME for parity 3＋ （quadratic; P 〈 0.01） and the entire cohort （quadratic; P 〈 0.01）. Similarly, the result of litter weight gain could be expressed as 2.65 and 2.66 g/Mcal of SID- Lys：ME ratio. Therefore, 3.25 Mcal/kg of ME was selected for Exp. 2 in which 150 sows （weighing 254.6 ± 7.3 kg and having an average parity of 3.4 ± 0.4） were allocated to one of five treatments in a completely randomized block design within parity （1, 2, and 3＋）. The experimental diets were formulated to contain 2.1, 2.4, 2.7, 3.0 or 3.3 g/Mcal of SID-Lys：ME ratio with all diets providing 3.25 Mcal/kg of ME. The diets were fed to the sows throughout a 28 day lactation. Sow body weight loss was affected by dietary treatment （parity 3＋ sows, P = 0.02; entire cohort, P 〈 0.01） and by sow parity （P 〈 0.01）. Litter weight at weaning and litter weight gain were affected by dietary treatment for parity 1, 2, 3＋ sows and the entire cohort （P 〈 0.01） as well as by sow parity （P 〈 0.01）. Plasma urea nitrogen （P 〈 0.01）, creatinine （P 〈 0.01） and non-esterifide fatty acids （P = 0.04） were decreased as the SID-Lys：ME ratio of the diet increased. Insulin-like growth factor-1 （P = 0.02）, estradiol （P 〈 0.01） and luteinizing hormone （P = 0.02） were increased as the SID-Lys：ME ratio in diet increased. Based on a broken-line model, the estimated SID-Lys： ME ratio to maximize litter weight gain was estimated to be 3.05 g/Mcal.

Prognostic significance of red blood cell distribution width in gastrointestinal disorders

The red blood cell distribution width(RDW) is a routinely measured and automatically reported blood parameter,which reflects the degree of anisocytosis. Recently,the baseline RDW was found to have clinical significance for assessing clinical outcome and severity of various pathological conditions including cardiovascular diseases,sepsis,cancers,leukemia,renal dysfunction and respiratory diseases. A myriad of factors,most of which ill-defined,have an impact on the red cell population dynamics(i.e.,production,maturation and turnover). A delay in the red blood cell clearance in pathological conditions represents one of the leading determinants of increased anisocytosis. Further study of RDW may reveal new insight into inflammation mechanisms. In this review,we specifically discuss the current literature about the association of RDW in various disease conditions involving the gastrointestinal and hepatobiliary systems. We also present some of the related measurements for their value in predicting clinical outcomes in such conditions. According to our data,RDW was found to be a valuable prognostic index in gastrointestinal disorders along with additional inflammatory biomarkers(i.e.,C reactive protein,erythrocyte sedimentation rate,and platelet count) and current disease severity indices used in clinical practice.

Role of corticotrophin releasing hormone in cerebral infarction-related gastrointestinal barrier dysfunction

BACKGROUND： Corticotrophin releasing hormone （CRH） is believed to mediate stress-induced behaviors, implying a broader, integrative role for the hormone in the psychological stress response, and studies on CRH in physical stress are few. This study was undertaken to investigate whether CRH plays an important role in cerebral infarction-related gastrointestinal barrier dysfunction.METHODS： Thirty male Wistar rats were randomly divided into a pseudo-operation group （group C, n=10）, a cerebral infarction group （group I, n=10）, and a cerebral infarction ＋ ic α-helical-CRH （9-41） group （group Aic, n=10）. Urine samples were collected to determine the levels of epinephrine, norepinephrine, cortisol, and sucrose. At 24 hours after establishment of the models, blood samples were taken to determine the activity of diamine oxidase （DAO） and the concentration of D-lactic acid （D-lac）. The stomach was taken to determine gastric Guth score, and the hypothalamus was also taken to determine tissue CRH protein expression using Western blotting.RESULTS： The hypothalamus CRH protein, the indicators of stress, the plasma DAO activity and plasma D-lac, urine sucrose exertion and gastric Guth score in group I were higher than those in groups Aic and C.CONCLUSIONS： After cerebral infarction, CRH in the hypothalamus was increased, the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system were activated, gastrointestinal permeability was increased, and gastrointestinal barrier function was destroyed. CRH receptor antagonist alleviated the gastrointestinal barrier function.
