ABSTRACT
Objective:To investigate the acute gastrointestinal injury (AGI) in patients with extracorporeal membrane oxygenation (ECMO) at the early stage of operation and its influencing factors.Methods:A total of 70 patients with ECMO who were hospitalized in the Emergency Care Unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed, and a total of 70 patients with ECMO who were hospitalized in the emergency care unit of Guangxi Zhuang Autonomous Region People's Hospital from September 2020 to December 2021 were retrospectively analyzed. According to the 2012 guidelines of the European Society of Intensive Care Medicine on the classification of acute gastrointestinal injury in critically ill patients, the patients were divided into AGI group and non-AGI group. The incidence of acute gastrointestinal injury in the early stage was statistically analyzed, and the results of blood gas analysis during ECMO loading and ECMO parameters, hemodynamic indexes and biochemical indexes after ECMO transfer were statistically analyzed. To explore the influencing factors and independent risk factors of AGI in the early stage. In addition, 70 patients were divided into successful group and non-successful group according to whether they were successfully withdrawn. The occurrence of acute gastrointestinal injury between the two groups was compared, and the effect of acute gastrointestinal injury on ECMO patients was analyzed.Results:Among the 70 ECMO patients, the incidence of early AGI was 71.43% (50 cases), and the components of AGI Ⅰ, Ⅱ, Ⅲ and Ⅳ were 18.57% (13 cases), 41.43% (29 cases), 11.43% (8 cases) and 0% (0 cases), respectively. ① Univariate analysis showed that systolic blood pressure, diastolic blood pressure, mean arterial pressure (MAP), vasoactive drug index (VIS), pH, lactic acid and BMI were significantly different between AGI group and non-AGI group when ECMO was used ( P < 0.05). Logistic binary regression analysis showed that BMI was an independent risk factor for early AGI in ECMO patients (ROC area 0.657, 95% confidence interval 0.522-0.791 ( P < 0.05), and Yoden index 0.15). (3) The AGI composition ratio of the unsuccessful group was higher than that of the unsuccessful group ( P < 0.05). Conclusions:Patients with ECMO have a high incidence of AGI in the early stage, mainly occurring in grade I and Ⅱ. Systolic blood pressure, diastolic blood pressure, MAP, VIS, pH, lactic acid and BMI when ECMO is put on are influential factors for the early development of AGI in ECMO patients, among which BMI is an independent risk factor for the early development of AGI in ECMO patients. The occurrence of AGI reduces the probability of successful withdrawal in ECMO patients.
ABSTRACT
Objective To investigate the effect of Yantiao Fang on apoptosis of intestinal epithelial cells in mice with acute gastrointestinal injury caused by sepsis by regulating the Rho/ROCK signaling pathway.Methods Seventy BALB/c mice were randomly divided into normal,sham,and model groups.Except for normal and sham groups,mice were subjected to cecal ligation and perforation to establish a mouse model of acute gastrointestinal injury caused by sepsis.The mouse models were randomly divided into model,Low,Medium,and High dose of Yantiao Fang,and ROCK inhibitor groups.Histopathological changes of the ileum were observed by HE staining.Serum levels of IL-1β,IL-6,TNF-α,and IL-10 were measured by ELISA.PCNA and Ki-67 expression was detected by immunohistochemistry.Cleaved caspase3 and Bax expression was detected by Western blot.ROCK and MLC mRNA expression in the ileum was measured by RT-qPCR.Results Compared with normal and sham groups,Chiu's pathological score,proinflammatory factor(IL-1β,IL-6,and TNF-α)levels,cleaved caspase3 and Bax protein expression,and ROCK and MLC mRNA levels were increased in the model group(P＜0.05).Moreover,anti-inflammatory mediator IL-10 and expression of PCNA and Ki-67 in the ileum were decreased in the model group(P＜0.05).Compared with the model group,histopathological changes of the ileum in all Yantiao Fang groups were improved by various degrees with the increase in dose.Chiu's pathological score,IL-1β,IL-6,and TNF-α serum levels,cleaved caspase3 and Bax protein expression,and ROCK and MLC mRNA levels were decreased in Yantian Fang groups(P＜0.05).The IL-10 level and expression of PCNA and Ki-67 in the ileum were increased in Yantian Fang groups(P＜0.05).Conclusions Yantiao Fang may inhibit apoptosis of intestinal epithelial cells in mice with acute gastrointestinal injury due to sepsis by regulating the Rho/ROCK signaling pathway,thereby alleviating intestinal tissue inflammation and ultimately preventing intestinal mucosal tissue injury.
ABSTRACT
Objective:To establish a prediction model of acute gastrointestinal injury (AGI) above grade II in elderly patients with severe pneumonia, and to evaluate and validate the model internally.Methods:A retrospective analysis was performed on 268 patients aged >65 years with severe pneumonia admitted to the Second People′s Hospital of Hefei from June 2019 to May 2022 (207 cases in the training set and 61 cases in the verification set). Sixteen indicators, including age, sex, underlying disease, pneumonia Severity index (PSI) score, dosage of sedative and analgesic drugs, and mechanical ventilation time of all patients were collected. After logistic regression analysis in the training set, a model was established to predict AGI above grade Ⅱ in elderly patients with severe pneumonia. Receiver operating characteristic (ROC) curve was drawed and correction curve was used to evaluate the reliability of the model. The model was internally validated by validation set data.Results:Among 207 patients with severe pneumonia in the training set, 50 patients developed AGI above grade Ⅱ during treatment. The prediction model was established by logistic regression analysis as follows: When L=Sequential Organ Failure Assessment (SOFA)×0.181+ PSI score×0.066+ propofol dosage×0.607+ reifentanil dosage×1.187, L>19.288, it can be considered that patients with severe pneumonia have a 93.24% chance of developing grade Ⅱ or above AGI. The ROC curve showed that the model was well differentiated, AUC=0.960. H-L test indicated (χ 2=7.39, P=0.496>0.05) the model fit was good. The sensitivity and specificity of the model were 82.00% and 96.82% respectively. AUC=94.58% (sensitivity 81.25%, specificity 93.33%), H-L test indicated ( χ 2=4.51, P=0.808>0.05) the prediction accuracy was 90.16%. Conclusions:The prediction model for AGI after severe pneumonia in elderly patients can be used clinically to help predict the occurrence of AGI in elderly patients with multiple injuries.

Objective:To investigate the clinical efficacy and prognostic influencing factors of open abdomen technique for acute pancreatitis with abdominal compartment syndrome (ACS).Methods:The retrospective cohort study was conducted. The clinical data of 186 patients of acute pancreatitis with ACS who were admitted to 6 hospitals, including 65 cases in the 910th Hospital of Joint Logistics Support Force of Chinese People′s Liberation Army, 46 cases in the First Affiliated Hospital of Wenzhou Medical University, 33 cases in the Fujian Provincial Hospital, 31 cases in the Second Affiliated Hospital of Fujian Medical University, 7 cases in the People′s Hospital Affiliated to Quanzhou Medical College, 4 cases in the Shishi General Hospital, from January 2013 to December 2020 were collected. There were 142 males and 44 females, aged (43±8)years. Observation indica-tors: (1) patients conditions after being treatment with open abdomen technique; (2) analysis of clinical characteristics in patients with different treatment outcomes; (3) changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes; (4) influencing factors for prognosis of patients. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or the continuity correction chi-square test. Repeated measurement data were analyzed using the repeated ANOVA. Spearman correlation analysis was used for correlation analyses. The COX regression model was used for univariate analysis and COX regression model with forward regression was used for multivariate analysis. Results:(1) Patients conditions after being treatment with open abdomen technique. Intra-abdominal pressure, oxygena-tion index, levels of lactic acid and sequential organ failure score of the 186 patients were (23.3±1.9)mmHg (1 mmHg=0.133 kPa), (121±24)mmHg, (5.0±3.4)mmol/L and 10.4±3.6 before the treatment with open abdomen technique and (11.2±2.9)mmHg, (222±38)mmHg, (3.2±2.1)mmol/L and 4.4±2.3 at postoperative 168 hours, showing significant differences in time effects before and after the treatment ( Ftime=855.26,208.50, 174.91,208.47, P<0.05). (2) Analysis of clinical characteristics in patients with different treatment outcomes. Of the 186 patients, 166 cases survived and were discharged, and 20 cases died during hospitalization. Age, sequential organ failure score, duration of ACS and levels of lactic acid during hospitalization before the treatment with open abdomen technique were (41±7)years, 9.4±3.4, 13(10,21)hours and (4.2±0.6)mmol/L in surviving patients, versus (45±6)years, 11.5±2.4, 65(39,84)hours and (5.2±0.5)mmol/L in dead patients, respectively, showing significant differences between them ( t=-2.10, -2.71, Z=-5.36, t=-7.16, P<0.05). Duration of postoperative acute gastro-intestinal injury, duration of continuous renal replacement therapy, time to liberation from mech-anical ventilation, duration of vasoactive drugs therapy, cases undergoing early abdominal closure, cases without intestinal fistula or with postoperative high-order intestinal fistula and low-order intestinal fistula during hospitalization after the treatment with open abdomen technique were 4(2,6)days, 4(3,7)days, 34(21,41)days, 3(2,6)days, 126, 131, 23, 12 in surviving patients, versus 13(10,17)days, 10(8,18)days, 0(0,3)days, 8(6,12)days, 1, 2, 15, 3 in dead patients, respectively, showing significant differences between them ( Z=-5.60, -3.75, -3.64, -3.06, χ2=41.43, 45.86, P<0.05). (3) Changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes. The volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in surviving patients during hospitalization were (0.29±0.10)mL/(kg·h), (4.2±0.6)mmol/L, 0.0 kcal/(kg·d) and 9.4±3.4 before the treatment with open abdomen technique and (2.22±0.15)mL/(kg·h), (1.9±0.7)mmol/L, (20.7±2.9)kcal/(kg·d) and 3.7±2.2 at postoperative 168 hours. The above indicators in dead patients during hospitalization were (0.28±0.08)mL/(kg·h), (5.2±0.5)mmol/L, 0.0kcal/(kg·d) and 11.5±2.4 before the treatment with open abdomen technique and (0.28±0.09)mL/(kg·h), (7.7±0.8)mmol/L, (4.6±1.8)kcal/(kg·d) and 12.4±2.1 at postoperative 168 hours. There were significant differences in time effects in the above indicators in surviving patients and dead patients before and after the treatment with open abdomen technique ( Ftime=425.57, 188.59, 394.84, 37.52, P<0.05). There were interactive effects between the above indicators and the treatment outcome at different time points ( Finteraction=383.14, 233.04, 169.83, 36.61, P<0.05). There were signifi-cant differences in the change trends of the above indicators between the surviving patients and the dead patients during hospitalization ( Fgouprs=2 739.56, 877.98, 542.05, 240.85, P<0.05). (4) Influen-cing factors for prognosis of patients. Results of univariate analysis showed that age, sequential organ failure score, duration of ACS before surgery, procalcitonin, lactic acid, postoperative high-order intestinal fistula, abdominal hemorrhage, duration of postoperative acute gastrointestinal injury, duration of continuous renal replacement therapy, duration of vasoactive drugs therapy, early abdominal closure were related factors influencing prognosis of patients under-going treatment with open abdomen technique ( hazard ratio=1.07, 1.18, 1.39, 1.16, 8.25, 12.26, 2.83, 1.29, 1.56, 1.41, 0.02, 95% confidence interval as 1.00-1.15, 1.45-2.27, 1.22-1.57, 1.02-1.32, 1.75-38.90, 7.37-41.23, 1.16-6.93, 1.22-1.37, 1.23-1.99, 1.08-1.84, 0.00-0.16, P<0.05). Results of multivariate analysis showed that extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury were independent risk factors influencing prognosis of patients undergoing treatment with open abdomen technique ( hazard ratio=1.05, 7.95, 1.17, 95% confidence interval as 1.01-1.32, 2.05-30.87, 1.13-1.95, P<0.05) and early abdominal closure was an independent protective factor ( hazard ratio=0.10, 95% confidence interval as 0.01-0.89, P<0.05). Results of Spearman correlation analysis showed that duration of ACS was positively correlated with sequential organ failure score before surgery ( r=0.71, P<0.05). Conclusions:Open abdomen technique is effective for acute pancreatitis with ACS. Extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury are independent risk factors for prognosis of patients during hospitalization and early abdominal closure is an independent protective factor.
ABSTRACT
Acute gastrointestinal dysfunction is a common and important complication of sepsis. As no exiting formal definition and classification of gastrointestinal dysfunction, most of the treatment strategies for gastrointestinal dysfunction are not based on clinical evidence, but on their own clinical experience. Experts of traditional Chinese medicine, integrated traditional Chinese and Western medicine and Western medicine from various disciplines in Shanghai are organized by the Shanghai Society of Integrated Traditional Chinese and Western Medicine and the Emergency Department Branch of Shanghai Physicians Association. After repeated discussion, literature search and formulation of the outline, we developed consensus on gastrointestinal dysfunction secondary to sepsis with integrating Traditional Chinese Medicine and Western medicine by consulting extensively on clinical experts in the fields of emergency medicine, gastroenterology, general surgery, infectious medicine and traditional Chinese medicine, and holding several expert forums and consultation meetings. This clinical expert consensus focused on acute gastrointestinal injury (AGI) classification and inducer of sepsis. In this consensus, the common symptoms, diagnosis, classifications, treatment strategies and suggestions of acute gastrointestinal injury or dysfunction secondary to sepsis were explored from the aspect of both Traditional Chinese Medicine and Western medicine.
ABSTRACT
@#To explore the incidence and grade of acute gastrointestinal injury（AGI）in patients with acute stroke，and the influence of gastrointestinal disorders on the mortality of stroke. Methods A total of 103 patients were recruited. According to the National Institutes of Health Stroke Scale（NIHSS）scores，they were divided into two groups：severe stroke patients（n=52）and mild to moderate stroke patients（n=51）.The incidence of gastrointestinal complications in the two groups are calculated. AGI classification was performed according to gastrointestinal symptoms. Binary logistic analysis was used to analyze the influencing factors of gastrointestinal failure in stroke patients，and KM curve was used to evaluate the effect of AGI classification on 28-day mortality in stroke patients. Results The incidence of gastrointestinal complications was 91.3%. There was no significant difference in the incidence of gastrointestinal disorders in the mild to moderate stroke and severe stroke groups（74.5% vs 75.0%，P>0.05）；The severe stroke group showed a higher incidence of gastrointestinal failure（7.8% vs 25.0%，P<0.05）. Multivariate logistic regression analysis showed：elevated NIHSS score was a risk factor for gastrointestinal failure after stroke（P<0.05）.Combining gastrointestinal failure significantly increased the 28-day mortality of stroke patients（χ2=53.08，P<0.001）. Conclusion Gastrointestinal complications are common in patients with acute stroke. NIHSS score is positively correlated with gastrointestinal failure. And patients with gastrointestinal failure have a worse prognosis.
ABSTRACT
Objective:To develop a prediction model of acute gastrointestinal injury (AGI) grading combined with qSOFA score for the diagnosis of sepsis, and evaluate its value.Methods:This was a prospective observational study. The patients with infection or suspected infection in the General Ward of Changshu Hospital Affiliated to Soochow University from September 2018 to September 2019 were included. Patients younger than 18 years, pregnant, abandoned treatment and died within 3 days after admission were excluded. Clinical characteristics, laboratory test results and AGI grading from 48 h before the infection to 24 h after the onset of infection were recorded. The patients were divided into the sepsis and non-sepsis groups according to whether they were diagnosed with sepsis. The patients were allocated randomly to a modeling cohort and a validation cohort with a ratio of 7:3. Univariate and multivariate logistic regression analyses were used to analyze the relevant risk factors for sepsis in the modeling cohort. Three types of diagnostic models were constructed in the modeling cohort: model A (qSOFA model), model B (the combined model of AGI grading and qSOFA score), and model C (the combined model of clinical parameters). The clinical usefulness of the diagnostic models was assessed by receiver operating characteristic curve (ROC), calibration curve and decision curve analysis (DCA) in the validation cohort. The nomograms were developed based on these models.Results:A total of 2 553 patients were enrolled in the study, 1 789 patients in the modeling cohort and 764 patients in the validation cohort. and 326 were diagnosed with sepsis. There was no statistical difference in the basic conditions of patients in the two groups. Univariate analysis showed that age, gender, the source of infection, temperature, heart rate, polypnea, changes in consciousness, severe edema, hyperglycemia, white blood cell, C-reactive protein and procalcitonin, hypotension, hypoxemia, acute oliguria, coagulation disorders, hyperlacticemia, capillary filling damage or piebaldskin, AGI grading and qSOFA score were significantly correlated with sepsis (all P<0.01). Multivariate logistic regression analysis showed that age ( OR=1.027, P<0.01), source of infection ( OR=2.809, P=0.03), hypotension ( OR=35.449, P<0.01), hypoxemia ( OR=57.018, P<0.01), and AGI grading ( OR=19.313, P<0.01) were significantly associated with sepsis. ROC analysis showed that the area under the curve (AUC) of model A, B and C were 0.784, 0.944 and 0.971 in the modeling cohort, and 0.832, 0.975 and 0.980 in the validation cohort, respectively. The sensitivities were 63.9%, 89.5% and 97.5% in the modeling cohort, and 72.7%, 90.9% and 96.6% in the validation cohort; and the specificities were 90.8%, 90.3% and 88.1% in the modeling cohort, and 92.2%, 94.5% and 92.8% in the validation cohort, respectively. AUC of model B and C were significantly higher than that of model A ( P<0.01). Model A in the validation cohort was poorly calibrated, with low accuracy and high risk of missed sepsis diagnosis ( P=0.044). The net benefits of model B and C were better than that of model A. Conclusions:AGI grading combined with qSOFA score has a high predictive value and accuracy in the diagnosis of sepsis.
ABSTRACT
To investigate the application of Acute Gastrointestinal Injury(AGI) grading in evaluating gastrointestinal failure in patients with acute pancreatitis(AP). In this retrospective observational study,patients presented with moderate severe AP and severe AP in our hospital from October 2013 to October 2016 were consecutively enrolled.Logistic regression analysis and receiver operating characteristic curve were used to explore and evaluate potential predictors of gastrointestinal failure. A total of 202 patients were included in this study,with 90 cases(44.6%) identified as gastrointestinal failure.Survival curve showed significantly increased risk of death in patients with gastrointestinal failure( < 0.05).Logistic regression analysis showed age(=1.06,95%:1.03-1.09,<0.001),complaint of stopping flatus and defecation(=7.02,95%:2.08-23.66,=0.002),increased counts of white blood cells in peripheral blood(=1.09,95%:1.02-1.17,=0.015),decreased level of serum albumin(=0.93,95%:0.86-1.00,=0.048),and increased level of serum creatinine at admission(=1.02,95%:1.01-1.04,=0.001) were the independent risk factors of gastrointestinal failure.The area under curves of Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) and Beside Index for Severity in Acute Pancreatitis (BISAP) scores in diagnosing gastrointestinal failure were 0.999 and 0.782,respectively. Gastrointestinal failure can remarkably increase the risk of death in patients with AP.Both APACHE Ⅱ and BISAP scores at admission are useful in diagnosing gastrointestinal failure in patients with AP.
ABSTRACT
Objective To investigate the classification,prognosis and causes of acute gastrointestinal injury(AGI) in PICU patients in our hospital. Methods Patients were included if they had been hospitalized in PICU at least 24 h before the AGI diagnosis from January 2015 to April 2018. Patients were classified ac-cording to severity of gastrointestinal dysfunction. Clinical characteristics,pediatric critical illness scores,pedi-atric logistic organ dysfunction score 2 and 28-day mortality,as well as mechanical ventilation were recorded. Results A total of 220 patients were enrolled. AGIⅠ-Ⅳ groups included 66 ( 30. 0%),97 ( 44. 1%), 37(16. 8%) and 20 ( 9. 1%) patients, respectively, while primary AGI and secondary AGI included 149(67. 7%) and 71 (32. 3%)patients,respectively. There was no significant difference among four groups in gender,hospitalization time in PICU and total hospitalization time (P>0. 05),but there were significant differences in median age,pediatric critical illness scores,pediatric logistic organ dysfunction score 2 and pro-portion of mechanical ventilation(P<0. 05). Median age( month) was 3 (1,15),11 (2,24),11 (2,36), and 4 (0. 5,11. 5),respectively in AGI Ⅰ-Ⅳ groups. The total 28-day mortality rate of AGI Ⅰ-Ⅳ groups accounted for 0,0,13. 2% and 3. 2%,respectively. Conclusion Patients in PICU are prone to AGI. AGIⅠand AGI Ⅱare common. The prognosis is associated with classification of AGI. The higher grades of AGI are,the worse prognosis is. The prognosis of AGI Ⅲ is the worst,because of different causes.
ABSTRACT
Objective To investigate the early diagnostic value of intra-abdominal pressure (IAP) combined with intestinal fatty acid binding protein (IFABP) for patients with mechanical ventilation complicated with acute gastrointestinal injury (AGI).Methods From August 2015 to December 2015,1 19 patients with mechanical ventilation were admitted to ICU in our hospital,with 78 cases of AGI patients and 41 cases of non-AGI patients.Multiple physiological indexes and laboratory indexes of the two groups were recorded and compared.Results There was no statistical difference in sex,age,APACHE Ⅱ score,BMI index,Lac and mean arterial pressure (MAP) between the two groups (P ＞0.05);the OR values of mechanical ventilation time,oxygenation index,end-expiratory positive pressure (PEEP),CIT,IFABP and IAP were more than 1,so these indicators were all risk factors for AGI in patients with mechanical ventilation.The area under the curve of IAP,IFABP,mechanical ventilation and PEEP were more than 0.5,indicating that these indicators have a certain predictive value for AGI patients with mechanical ventilation.The sensitivity and specificity of IAP were 95％ and 80％ respectively,and the sensitivity and specificity of IFABP were 87.5％ and 50％,respectively.IAP was correlated with IFABP (r =0.621,P =0.031).Conclusions Mechanical ventilation time,oxygenation index,PEEP,CIT,IFABP,and IAP are risk factors for AGI patients with mechanical ventilation.IAP,IFABP,mechanical ventilation time and PEEP have a certain predictive value for AGI patients with mechanical ventilation.The diagnostic value of IAP and IFABP is high,and the two are closely related.Combined application can provide a certain objective basis for clinical AGI diagnosis.
ABSTRACT
Objective To observe the effects of Lianggesan on serum citrulline and intestinal fatty acid binding protein (IFABP) levels in patients with mechanical ventilation and acute gastrointestinal injury (AGI). Methods Eighty patients with mechanical ventilation and AGI admitted to Tianjin First Center Hospital from May to December 2017 were divided into a conventional treatment group and a traditional Chinese medicine (TCM) treatment group according to different treatment methods, 40 cases in each group; 10 patients with mechanical ventilation but without AGI were selected as a control group. All patients were given invasive mechanical ventilation after admission, and the gastrointestinal tract intervention was carried out according to AGI grading treatment process; Lianggesan (compositions:forsythia suspensa 30 g, scutellaria 10 g, gardenia 10 g, bamboo leaf 10 g, rhubarb 10 g, mint 6 g, mirabilite 6 g, licorice 15 g) was added to the TCM treatment group on the basis of the conventional treatment. The above TCM drug used was a single Chinese medicine granule produced by Jiangyin Tianjiang Pharmaceutical Co., Ltd. Each single Chinese herbal granule was proportionally poured into 200 mL boiling water at 80-100 ℃, 100 mL each time, twice daily nasal feeding for one week. The changes of serum citrulline and IFABP levels were observed before and 1, 3, 5 and 7 days after treatment in the three groups. Results Before treatment, serum citrulline levels in the conventional treatment group and the TCM treatment group were significantly lower than those in the control group (μmol/L: 19.84±4.74, 20.84±4.65 vs. 28.89±2.18, both P < 0.05), and IFABP levels were significantly higher than those in the control group (ng/L:571.89±42.89, 552.49±44.78 vs. 155.68±22.95, both P < 0.05), there were no significant differences between the conventional treatment group and the TCM treatment group (P > 0.05); with the extension of treatment time, the levels of citrulline in the conventional and TCM treatment groups were decreased first and then increased gradually, reaching the valley value on the first day of treatment [the two groups were (16.12±4.44), (18.49±4.59) μmol/L] respectively, and then increased gradually, reaching the peak value on the 7th day of treatment, the increased range of citrulline in the TCM treatment group was more obvious than that in the conventional treatment group (μmol/L: 26.77±4.18 vs. 22.75±3.07, P < 0.05), and the treatment lasted for 5 days, and 7 days, the level of citrulline in the TCM treatment group was close to that in the control group; the IFABP levels in the conventional treatment group and the TCM treatment group were increased first and then decreased gradually, reaching the peak value on the first day of treatment [the two groups were (654.23±63.24), (630.32±49.11) ng/L] respectively, and then decreased gradually, reaching the trough value on the 7th day of treatment, the degree of decrease in the TCM treatment group was more obvious than that in the conventional treatment group (ng/L: 262.21±30.89 vs. 375.43±44.43, P < 0.05), but the level of IFABP in the TCM treatment group was still significantly higher than that in the control group (ng/L: 262.21±30.89 vs. 158.95±29.34, P < 0.05). Conclusion Lianggesan can elevate the serum citrulline level, reduce the serum IFABP level, and effectively improve the intestinal function of patients with mechanical ventilation and AGI.

AUC of high AGI grade for predicting patients′ death and infectious pancreatic necrosis was 0.944(95% CI 0.916-0.972) and0.779(95% CI 0.723-0.836), respectively, which was higher than those of APACHEⅡ and Marshall score.@*Conclusions@#AGI grading system can be applied to better assess the severity of acute pancreatitis, and its predictive value for death and infectious pancreatic necrosis was higher than that of APACHEⅡ, MCTSI and Marshall score.
ABSTRACT
OBJECTIVE: To analyze the factors influencing postpyloric placement of spiral nasoenteral feeding tube(NET) in neurocritical care patients and establish a visualized prediction model. METHODS: Patients in Neurological Intensive Care Unit(NICU)who undertook postpyloric placement of NET after receiving prokinetics from Apr 2012 to Mar 2018 were included for retrospective analysis. The patients were divided into the success and failure group base on whether the tube tip entered into duodenum(or beyond)or not confirmed by bedside X-ray 24 hours later. The baseline data, APACHE Ⅱ score(acute physiology and chronic health evaluation Ⅱ), AGI grade(acute gastrointestinal injury), therapeutic measures and agents administered were recorded. Univariate and multivariate Logistic regression analysis was used to identify the potential factors affecting the postpyloric placement of NET. Based on those factors, a predicting model was established and visualized into an easy-to-use nomogram. RESULTS: A total of 241 patients including146 male and 95 female were enrolled for the study, with an median age of 58 years, median APACHEⅡscore of 20, median AGI of Ⅰ.The placement succeeded in 119(49.4%) of 241 patients. Logistic regression analysis demonstrated that APACHE Ⅱ score, sedatives and analgesics, vasopressors and AGI grade were among the influencing factors. A prediction model with a ROC-AUC of 0.8002 were established and visualized into a nomogram. CONCLUSION: APACHE Ⅱ score, sedatives and analgesics, vasopressors and AGI grade are the factors influencing success of postpyloric NET placement in neurocritical care patients, which incorporate a predicting model that can be visualized into a nomogram. The nomogram provided intensivists an easy-to-use decision support tool in NET placements.

ABSTRACT
Background: Gastrointestinal and mesenteric injuries are the third most common type of injury from blunt trauma abdomen and are associated with high rates of morbidity and mortality.Objectives: To determine the clinico-demographic profile, localization of injury, diagnostic and management methods and the outcome in cases of hollow viscus injury (HVI) following blunt trauma abdomen which were admitted to our unit. Methods: Records of patients who were admitted emergently with gastrointestinal injuries and blunt abdominal trauma between July 2014 and July 2016 were reviewed retrospectively. Results: The study group comprised 65 patients with mean age of 33.3 ± 16.2 years and a male predominance (89.2%). The commonest cause of injury was road traffic accident in 44 (67.7%) cases. Ileum was the most common site of injury detected in 31 (41.3%) followed by jejunum in 26 (34.7%) cases. Treatment comprised primary closure of perforation in 48 (64%) cases, segmental resection and anastomosis in 22 (29.3%), and stoma in 5 (6.7%) cases. Three out of 5 cases of anastomotic leak occurred in patients who were operated at 8-24 hours or beyond. Associated injury to intra-abdominal solid viscera and other sites were present in 30.7%. The mean duration of hospitalization was longer in patients with associated injuries as compared to those with isolated HVI (12.2±4.6 days versus 9.3±0.8 days). Conclusion: Early diagnosis followed by prompt surgical intervention and careful monitoring for associated injuries is the key to favourable outcome in blunt HVI.
ABSTRACT
Objective To study the occurrence of acute gastrointestinal injury under different critical status in Pediatric Intensive Care Unit,and to assess the connection between citrulline and acute gastrointestinal injury.To ana-lyze the correlation among serum citrulline and C-reaction protein(CRP),procalcitonin(PCT),creatinine,urea nitro-gen,bilirubin,lactate,albumin.To study the role of citrulline in evaluating the children condition,prognosis and changes in critically ill children.Methods Ninety-six pediatric patients who were critically ill at the Pediatric Intensive Care Unit of the Second Hospital of Lanzhou University were selected,excluding those with primary gastrointestinal diseases and chronic kidney disease.Clinical features were recorded and CRP,PCT,creatinine,urea nitrogen,bilirubin,lactate, and albumin were measured.Serum citrulline concentrations were measured by high performance liquid chromatography in 65 patients with gastrointestinal injury,and sensitivity,specificity and area under the receiver operating characteristic (ROC)curve were calculated.Results The incidence of acute gastrointestinal injuries in non-critical group,critical group,reorganization critical group were 47.06%(16/34 cases),75.00%(36/48 cases),92.86%(13/14 cases) (χ2=11.848,P=0.003).The serum citrulline concentrations of gastrointestinal injury group and non- gastrointesti-nal injury group were(14.655 ± 8.231)μmol/L,(23.522 ± 11.079)μmol/L(t=4.398,P<0.05).The area under ROC of citrulline was 0.079 8.Serum citrulline concentrations increased significantly in infants with very severe gastro-intestinal injury after 3 days of treatment compared with admission[(26. 40 ± 16. 10)μmol/L vs.(14. 40 ± 6.82)μmol/L,t=5.524,P=0.029].The lower serum citrulline levels the children had,the higher mortality was. There were negative correlations among serum citrullin and CRP,PCT and length of hospital stay(r = -0. 319,-0.299,-0.364,P=0.003,0.006,0.001).There were no correlations among serum citrullin and blood urea nitro-gen,lactic acid,albumin,and bilirubin levels.Conclusion The more critically ill children have a higher incidence of acute gastrointestinal injury and the worse the prognosis.Serum citrulline levels may well reflect the extent of acute gas-trointestinal injury and the outcome.Perhaps it can be one of the reliable markers to evaluate the function of gastrointes-tinal and participate in assessing critical condition and prognosis in critical ill children ness.
ABSTRACT
Objective To develop a traditional Chinese medicine (TCM) syndrome score scale for acute gastrointestinal injury (AGI) in sepsis, and to carry out its reliability and validity analyses and its clinical preliminary application. Methods ① According to the characteristics of intensive care unit (ICU) patients, combined with the understanding of etiology, pathogenesis and physical signs of TCM and literature search, a preliminary framework of scoring system for TCM syndromes of AGI in sepsis was constructed to carry out the scoring by this scale. ② After the scale and data were obtained, the analyses of split-half reliability (indicated by Guttman's split-half reliability of the a and b groups), test-retest reliability and the internal consistency reliability (expressed by the Cronbach's coefficient α) were carried out, and the structural validity and criterion validity were also analyzed. ③ The AGI patients were divided into two groups according to the 28-day survival and death conditions, and the AGI TCM syndrome score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, and multiple organ dysfunction syndrome (MODS) score were compared between the two groups to determine the best cut-off point for survival analysis. Results ① The first draft of the septic AGI TCM syndrome rating scale was prepared, The TCM syndrome indicators include: abdominal distension, constipation/diarrhea, diet situation, vomiting/stomach retention, tongue proper, tongue coating, pulse manifestation, belching, body temperature, and accompanied syndrome, there were 6 points for scoring, 0 - 6 points, and they were divided into normal (0 points), mild (2 points), moderate (4 points), and severe (6 points) in severity. ② Eighty-eight patients with septic AGI were included in the final statistics. The retest of correlation coefficient of this scale was R = 0.974 (> 0.85), Guttman's split-half reliability was 0.793 (> 0.7) and the Cronbach's coefficient α was > 0.7. This scale was suitable for factor analysis. After rotation, 3 factors were determined, which were named as TCM syndrome differentiation, related physical signs, and gastrointestinal tolerance. After modeling, the confirmatory factor analysis showed that the model approximate error root mean square (RMSEA) was 0.07 (< 0.08), and the goodness of fit index (CFI) = 0.90; the Pearson correlation analyses between the criteria validity of APACHE Ⅱ, SOFA, MODS scores and TCM 1 score and TCM 2 score of this scale showed that the r values were 0.802 and 0.752, 0.524 and 0.519, 0.619 and 0.590, respectively, all P < 0.01. ③ Compared with the survival group, TCM score (33.73±5.95 vs. 37.28±5.26, t = 2.945, P = 0.004), the APACHE Ⅱ score (19.90±4.47 vs. 22.28±5.79, t = 2.069, P = 0.043), SOFA score (8.73±1.11 vs. 9.64±1.38, t = 3.329, P = 0.020) in the death group were significantly decreased; MODS score in the death group showed a decreasing trend (6.65±1.22 vs. 7.28±1.60, t = 2.078, P = 0.050). Cox regression analysis showed that when the survival analysis was performed with a cut-off point of 35, the 28-day survival rate of patients with TCM syndrome score ≥ 35 was significantly lower than that of patients with < 35 score, χ2= 6.362, P = 0.012. Conclusions The TCM syndrome rating scale for AGI in sepsis was successfully prepared. The statistical reliability and validity of this scale are good. Preliminary clinical application shows that this scale can predict the prognosis and severity of patients with septic AGI.

ABSTRACT
Objective:To analyze the value of low dose enteral nutrition (EN) in treatment of septic shock combined with acute gastrointestinal injury Ⅲ (AGI Ⅲ).Methods:Clinical data of septic shock patients combined with AGI Ⅲ admitted at our hospital were analyzed.Patients were divided into two groups according to the nutrition therapy they received:treatment group (EN,n =41) and control group (no EN,n =46).The mortality and ICU hospital stays were collected.The intestinal barrier,inflammatory cytokines,and oxidative stress were evaluated before and after EN treatment.Results:For patients in the treatment group,the dosages of EN ranged from 200 to 410 kcal/d,with the median dose of 350 kcal/d.No significant differences were found on death rates between the two groups (24.4％vs 32.6％,P =0.398).Patients in the treatment group had shorter ICU hospital stays than those of the control group (11.8 ± 3.7 vs 16.2 ± 5.3,P ＜0.01).After one week EN treatment,patients in the treatment group had lower levels of CRP,IL-6,TNF-α,diamine oxidase,endotoxin and D-lactate than those of the control group (P ＜ 0.05).Conclusion:For septic shock patients combined with AGI Ⅲ,low dose EN can improve the intestinal barrier function and systemic inflammatory responses.
