RESUMEN
Objective To investigate the factors related to severe acute pancreatitis (SAP) with intestine functional disturbance (IFD) and to establish the multiple predictor models of SAP with IFD. Methods Clinical data of consecutive SAP patients admitted to department of gastroenterology of Beijing Shijitan Hospital, Capital Medical University from January 2015 to March 2019 were retrospectively collected and analyzed. According to the occurrence of IFD at 48 hours after onset, the patients were divided into IFD group and control group. The clinical indicators within 4 hours after admission were compared between the two groups, and the independent predictive factors for SAP with IFD were screened by single factor analysis and multiple classified Logistic regression analysis. The unweighted predictive score (unwScore) and weighted predictive score (wScore) models were constructed by combining the independent predictors. The receiver operating characteristic (ROC) curves of SAP patients with IFD were plotted by independent predictive factors and predictive models, and the clinical predictive effect of each independent predictive index and predictive models were analyzed. Results A total of 149 patients with SAP were enrolled, including 87 males and 62 females, with age of (52.8±18.1) years old. There were 45 patients in IFD group and 104 patients in control group. Univariate analysis and multiple classified Logistic regression analysis showed that high sensitive C-reactive protein (hs-CRP), blood urea nitrogen (BUN), serum creatinine (SCr), serum calcium (Ca), procalcitonin (PCT) and neutrophil-lymphocyte ratio (NLR) were independent predictive factors of SAP with IFD. The ROC curve was used to calculate the cut-off value of the above indexes to predict IFD, and unwScore model was established. The cut-off score of IFD prediction by the unwScore model was 3 points, and the probability of IFD increased with the increase of the score. The area under ROC curve (AUC) of unwScore was 0.944, the sensitivity was 95.6%, the specificity was 94.2%, the positive predictive value (PPV) was 87.8%, and the negative predictive value (NPV) was 98.0%. The binary Logistic regression analysis of hs-CRP, BUN, Ca, SCr, PCT and NLR were carried out, and wScore model was established. The AUC of wScore was 0.959, the sensitivity was 95.9%, the specificity was 96.2%, the PPV was 91.5%, and the NPV was 98.1%;predictive value was superior to each independent index and unwScore model. Conclusions hs-CRP, BUN, SCr, Ca, PCT and NLR were independent predictive factors of SAP with IFD. The multiple predictor models of SAP with IFD have a good predictive efficiency which may provide valuable clinical reference for prediction and treatment.

Objective To observe the effects of Dahuangfuzi decoction on the intestine barrier functional of acute necrotizing pancreatitis in rats. Methods The 60 rats were randomly divided into sham operation group ( n = 19 ), ANP group ( n = 21 ), and Dahuangfuzi treatment group ( n = 20). The rats of ANP group were induced by injecting 1 ml/kg of 4% sodium taurocholate into the pancreatiobiliary duct, and jejunal fistula was esablished. The rats of treatment group received Dahuangfuzi decoction (2 ml, repeated at 4 and 8 h)through jejunum distal stoma tube 0. 5 h after ANP induction. The other 2 groups received same amount of normal saline. Blood sample was collected through abdominal aorta, 24 h after ANP induction, and the serum amylase, endotoxin, D-lactate, plasma diamine oxidase (DAO) were detected. Pancreas, small intestine tissue was harvested for pathologic examination, index of intestinal epithelial damage was measured and ultrastructural changes in small intestinal mucosa was observed. Results The expression of serum amylase, endotoxin,D-lactate, DAO in sham operation group was ( 152 ± 32 ) U/L, (6.95 ± 2.10) pg/L, ( 3.96 ± 1.08 ) μg/mland ( 14.26 ± 2.67 ) μg/ml, while the corresponding values were ( 1549 ± 93 ) U/L, (40.48 ± 3.41 ) pg/L,( 12.34 ± 1.23 ) μg/ml and ( 80.28 ± 3.54) μg/ml in ANP group, and they were (655 ± 49 ) U/L, ( 19.55 ±2.50) pg/L, (6.75 ± 1.36 ) μg/mland ( 20.69 ± 7.53 ) μg/ml in treatment group. The values in ANP group were significantly higher than those in sham operation group. The values in treatment group were significantly lower than those in ANP group, but significantly higher than those in sham operation group ( P ＜ 0.05 or P ＜0. 01 ). The thickness and height of intestinal mucosa in ANP group were ( 389.44 ± 29.87 )μm and ( 16.52 ±3.73) μm, which were significantly lower than those in treatment group [(501.95 ± 45.38 )μm, (27.82 ±5.17)] μm, and in sham operation group [( 658.72 ± 57.49 ) μm, ( 35.49 ± 6.43 )μm, Index of intestional epitholial donage in ANP group was 3.72 ± 0.65 which is significently higher than those in theatment (2.12 ±0.37 ) and in sham operation group (0.85 ± 0.24). The intestinal mucosa histological and ultrastructural changes in Dahuangfuzi treatment group were better than those in ANP group. Conclusions Dahuangfuzidecoction can significantly decrease the damage of intestine barrier function in ANP rats.
RESUMEN
Objective: To evaluate the protective effect of N-acetylcysteine(NAC) on the small intestine of male rats after X ray irradiation of the whole abdominal region. Methods: Sixty male Spraque-Dawley rats were divided in normal control group (n=12), irradiation group(n=12), and NAC groups(50, 200, and 300 mg/kg, n=12). Irradiation injury was induced with X ray at a single dose of 1 000 cGy(source-to-skin distance 80 cm) for the abdominal regions after the animals had been anesthetized with sodium thiopental(40 mg/kg, i. p.). NAC was started 3 days before irradiation and administered for 3 more days after irradiation, and then rats were euthanized after 12 h fasting. The terminal ileum samples were collected for crypt survival assay and counting in ileal villi. The blood samples were collected for examination of superoxide dismutase(SOD) activity, and the contents of malondialdehyde(MDA) and glutathione hormone(GSH) in the small intestine. The plasma levels of D-lactate and diamine oxidase(DAO) were also measured. Results: The mucosal structure of the terminal ileum was damaged after irradiation. The plasma levels of D-lactate, DAO and the content of MDA were significantly increased; the activity of SOD and the content of GSH were significantly decreased(P<0.01). NAC at different dosages increased crypt survival rates and the number of ileal villi in the terminal ileum (P<0.05, P<0.01), enhanced the activities of SOD and content of GSH (P<0.05, P<0.01), and deceased the concentrations of D-lactate, DAO and MDA (P<0.05, P<0.01). Conclusion: NAC may protect the small intestine from irradiation-induced injury by protecting the intestinal mucosal barrier, eliminating oxygen free radicals, and maintaining the internal oxidative balance and the structure and function of intestinal mucous.

Objective: To evaluate the protective effect of Shenfu injection (SFI) against intestinal barrier dysfunction and second hit in rats with severe acute pancreatitis (SAP). Methods: Fifty-four male Wistar rats were randomly divided into sham operation group (n = 6), SAP group (n = 24), and SAP + SFI group (10 ml/kg body wt, n = 24). Sham operation group underwent laparotomy only. SAP model was established by retrograde injection of 5% sodium taurocholate into the bilipancreatic duct of Wistar rats. SAP+SFI group was given SFI (10 ml/kg) intaperitoneally 2 h before SAP establishment. Rats were sacrificed at 3,6,12 and 24 hours after operation. The samples of pancreas, lung and liver were collected for measuring the levels of myeloperoxidase (MPO) at 3,6,12, and 24 h after injection of sodium taurocholate. The pathological changes of the terminal ilea were observed under light microscopy, and the blood levels of diamine oxidase (DAO), tumor necrosis factor alpha (TNF-α) and interleukin-6(IL-6) were also measured at different time points. Results: The blood levels of TNF-α, IL-6 and DAO in SAP group were significantly higher than those in the sham operation group at all time points (P<0.01). The levels of intrapulmonary, intrapancreatic and intrahepatic MPO in SAP group were significantly than those in the sham operation group at 6,12, and 24 hours (P<0.01). The contents of DAO, TNF-α and IL-6 were significantly decreased in SAP + SFI group compared with in SAP group at all time points (P<0.05 or P<0.01). The contents of intrapulmonary, intrapancreatic and intrahepatic MPO were significantly decreased in SAP+SFI group compared with SAP group at 6,12, and 24 h after operation (P<0.05 or P<0.01). Intestinal pathological damages were obviously milder in SAP+SFI group than that in SAP group at 24 h after operation. Conclusion: SFI can protect the small intestine mucosal barrier and other organs from second hit by reducing the polymorphonuclear leucocyte detaining and inhibiting TNF-α and IL-6.
RESUMEN
Objective To investigate the prognostic factors of life and functional outcome of the first hemiparetic stroke patients. Methods One hundred and eighteen stroke subjects were registered prospectively. The Barthel index (BI) , Rankin scale (RS) , Mortricity index(MI) , Mini-mental state examination (MMSE) , Montgomery-Asberg depression scale (MADRS) and a scale of general state and risk factors were used to evaluate at the 48th hour, the 15th day and the 90th day after stroke. Results The patients' performance, as demonstrated by their scores with all the evaluation instruments, changed significantly at all the time points of evaluation after stroke (P ＜0.05). There was no significant difference between the performance at the 48th hour and the 15th day after stroke ( P ＞ 0.05 ). But at the 90th day after stroke, the activity of daily living performance and the depression status recovered significantly (P ＜ 0.01 ). Logistic regression analysis showed that, such factors as pneumonia, urinary incontinence within 48th hour and deep sensation disturbance might adversely influence patients' activity of daily living performance at the 90th day after stroke; the muscle strength of upper extremities at the 48th hour, and MMSE scores at the 15th day after stroke acted as the protective factors. Conclusions The stroke patients improved significantly with regard to their clinical and functional manifestations when evaluated 90 days after stroke onset. The main factors influencing the activity of daily living performance 90 days after stroke onset included deep sensation disturbance,pneumonia, urinary incontinence and muscles strength of upper extremities at 48th hour, and MMSE scores at the 15th days after onset.
RESUMEN
Objective To investigate the effect of Da-Cheng-Qi decoction on enteric functional disturbance in rats with acute experimental pancreatitis and its potential mechanism. Methods Seventy-two SD rats were randomly divided into sham operation group, acute pancreatitis (AP) group and Da-Cheng-Qi decoction treated group with 24 each. The AP model was induced by retrograde injection of sodium taurocholate (0.1 ml/100 g) into bitiopancreatic duet. Before modeling, the rats in treatment group received Da-Cheng-Qi decoction (2 g/100 g), and the rats in other two groups received 0.9% NaCl solution. The rats were sacrificed at 3, 6 and 12 hours with 8 each, and the blood samples were taken for detecting the level of amylase and the contents of 5-hydroxytryptamine (5-HT) by enzyme-linked immunosorbent assay. The colonic tissues 10 cm apart from trans-ligament incluing jejunum, terminal ileum and sigmoid colon were collected for examining the expressions of 5-HT_3 and 5-HT_4mRNA and proteins by RT-PCR and Western blotting respectively. Results ① The levels of serum amylase and 5-HT in AP group and treatment group were significantly higher than those in sham operation group (P<0. 01), but they were lower in treatment group than in AP group at each time points (P<0. 05). The level of 5-HT was increased in the initial stage and then decreased gradually both in AP group and treatment group. ③ The expressions of 5-HT_3 and 5-HT_4 mRNA and proteins were significantly decreased in the jejunum, terminal ileum and sigmoid colon in AP group compared with sham operation group (P<0. 01). Whereas the expressions of 5-HT_3 mRNA and protein,but not 5-HT_4, were increased in the treatment group in comparison with AP group (P<0.05). Conclusions The level of 5-HT is significantly increased in acute pancreatitis, but its receptors (5-HT_3 and 5-HT_4) are decreased, which may induce enteric functional disturbance. The Da-Cheng-Qi decoction may improve enteric dynamic failure by increasing the expression of 5-HT_4 and may be a choice for treatment of acute pancreatitis with enteric dynamic failure
RESUMEN
Electrolyte disturbance was prominent in patients with severe acute mountain sickness. In these patients hypoxia caused water and salt retension together with vasoactive substances and excessive free radicals might play important roles in the development of multiple organ dysfunction syndrome (MODS). More attention should be given to electrolyte monitoring in dealing with these severe mountain sickness in field.
RESUMEN
Many patients have functional disturbances after a traditional restorative rectal resection, complaining of urgency, frequent bowel movements, and occasional fecal incontinence. The rectal reservoir function is disturbed, and this is related to the size of the rectal remnant and the elastic properties of the neorectal wall. A straight anastomosis is recommended when the reservoir capacity of the rectal remnant is sufficient. A side-to-end anastomosis is probably preferable to an end-to-end anastomosis. If a straight anastomosis is considered, the descending colon is much better than the sigmoid colon. If optimal functional results are to be obtained soon after surgery, construction of a pouch is recommended when the rectal remnant is very short. There seems to be a balance between continence without urgency and evacuation ability. For patients with weak sphincter muscles and habitually loose feces, the surgeon should tailor the length of the pouch to be longer whereas it should be made smaller for patients with a pre-operative tendency toward constipation. In the long-term, bowel adaptation may also enable the function after a straight anastomosis to approximate that of a colonic J-pouch anal anastomosis. Where the pelvis is too narrow for a bulky colonic J-pouch anal anastomosis, a coloplasty-anal- anastomosis is an option. The latter results in postoperative bowel function comparable with that of the colonic J-pouch. Traditionally, poor bowel function has been managed expectantly. The colonic adaptation may take one or two years to occur after a low anterior resection. The patient is advised to take adequate soluble fiber in the diet and to avoid foods which aggravate the bowel dysfunction. Those with increased stool frequency are prescribed constipating agents to help control the symptoms. Patients with rectal evacuation problems are prescribed regular laxatives and enemas.
