Objective: To study the mechanisms of cold exposure mediated ileum mechanical barrier injury in mice. Methods: Twenty mice were randomly divided into the control and cold exposure groups. Both the control and cold exposure groups were placed in the climate room with (24±2)℃ and 40% humidity. The mice in the cold exposure group were moved to the climate room at (4±2)℃ every day for 3 hours for three consecutive weeks. Three weeks later, the ileum tissues of mice were collected. Changes in ileum tissue structure were observed by hematoxylin-eosin staining and Masson staining. The related protein expression levels of the tight junction, inflammatory cytokines, and the NF-κB pathway were detected by Western blot. Results: Compared with the control group, the circular muscle layer of the ileum in cold exposed mice became thin, a large number of inflammatory cells infiltrated, the length of villi became short, the depth of recess was increased, and tissue fibrosis appeared. The expression levels of ideal tight junction-associated proteins in cold exposed mice were decreased significantly (P<0.05), while the protein expression levels of IL-1β, IL-6 and phosphorescent p65 were increased significantly (P<0.05). Conclusion: Cold exposure can damage the tight junction of the mouse ileum, destroy the integrity of the mechanical barrier and activate the NF-κB signaling pathway to promote the occurrence of the inflammatory response.

To explore the mechanism of Suanzaoren Decoction in the treatment of insomnia from endogenous bile acid regulation, the present study investigated the hepatoprotective effect of Suanzaoren Decoction and the molecular changes of bile acids in the serum, liver, and ileum of insomnia model mice and Suanzaoren Decoction treated mice. The insomnia model in mice was established by the sleep deprivation method. After Suanzaoren Decoction(48.96 mg·kg~(-1)·d~(-1)) intervention by gavage for 7 days, the related indicators, such as water consumption, food intake, body weight, aspartate aminotransferase(AST), alanine transaminase(ALT), and total bile acid(TBA) were detected, and the pathological changes of the liver and ileum were observed. The molecular levels and distribution of 23 bile acids in the serum, liver, and ileum were analyzed by UPLC-MS/MS combined with principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA). The results showed that Suanzaoren Decoction could improve the decreased water consumption and food intake, weight loss, and increased AST and ALT in the model group, and effectively reverse the injury and inflammation in the liver and ileum. The bile acids in the liver of the insomnia model mice were in the stage of decompensation, and the bile acids in the serum, liver, and ileum of the mice decreased or increased. Suanzaoren Decoction could regulate the anomaly of some bile acids back to normal. Seven bile acids including glycoursodeoxycholic acid(GUDCA), glycodesoxycholic acid(GDCA), tauro-α-MCA(T-α-MCA), α-MCA, taurodeoxycholate(TDCA), T-β-MCA, and LCA were screened out as the main discriminant components by PLS-DA. It is concluded that Suanzaoren Decoction possesses the hepatoprotective effect and bile acids could serve as the biochemical indicators to evaluate the drug efficacy in the treatment of abnormal liver functions caused by insomnia. The mechanism of Suanzao-ren Decoction in soothing the liver, resolving depression, tranquilizing the mind, and improving sleep may be related to the molecular regulation of bile acid signals.

OBJECTIVES:
At present, there are many studies on Crohn's disease of terminal ileum and colon, but few studies on Crohn's disease of small intestine alone. This study aims to analyze the clinical features and therapeutic effect of small bowel in adult patients with Crohn's disease so as to strengthen the diagnosis and treatment for this disease.
METHODS:
From July 1, 2015 to October 31, 2018, patients with small bowel Crohn's disease at Department of Gastroenterology, Third Xiangya Hospital of Central South University, were enrolled. At the same time, patients' demographics and clinical data were collected.
RESULTS:
A total of 44 patients were small bowel Crohn's disease. Among them, 40 patients were male. The age at diagnosis was (35.8±10.3) years old and disease duration was (35.2±59.5) months. The subtypes included 29(65.9%) of ileum, 7(15.9%) of jejunum, 8(18.2%) of ileum with jejunum. There were 27(61.4%) of stricture behavior, 4(9.1%) of penetrating behavior, and 13(29.5%) of non-stricture and non-penetrating behavior. Endoscopic visible stricture (29/85, 34.1%) was common, followed by longitudinal ulcers (27/85, 31.8%). Non-caseate granulomatous were found in 2 cases (4.5%). The score of Crohn's disease activity index was correlated to hemoglobin, hematocrit, and erythrocyte sedimentation rate (all
CONCLUSIONS
Patients with ileum account for a large proportion in patients with small bowel Crohn's disease. Stricture is more common in small bowel Crohn's disease. Stricture and longitudinal ulcer are more common under enteroscopy. Crohn's disease activity index is correlated to hemoglobin, red blood cell specific volume, and erythrocyte sedimentation rate. The most common complication is intestinal obstruction. Mesalazine is less effective on small bowel Crohn's disease.

To develop an ideal surgical procedure for neobladder reconstruction in experimental porcine models. Six experimental female pigs weighting 28-33 kg underwent transplantation of autologous peritoneum for bladder reconstruction under general anesthesia.The flaps were used to reconstruct the orthotopic neobladder by suturing with the edges of the triangle and neck of the remnant bladder.The ureteral catheters were removed on the 5 postoperative day and the balloon catheter was removed on the 7 postoperative day.Voiding behaviour was monitored.The animals were euthanized at week 12 for routine pathology,immunohistochemistry,and electron microscopy. All the pigs survived after the surgery,and no postoperative complication such as peritonitis,intestinal obstruction,or urinary fistula was observed.All the peritoneum-ileum composite free valves survived after transplantation.Voiding behaviour was normal after catheter removal,and the urine was clear.At autopsy,reconstructed bladders were healthy.Pathological examination showed the neobladder had been covered by continuous urothelium while the peritoneum disappeared and showed no ileal mucosa regrowth and residual.Scanning electron microscope showed the transitional cells of neobladder were complete and orderly,and the urothelium around suture border was continuous and showed no malposition. Reconstruction of bladder by autologous peritoneum and ileal seromuscular flaps is an ideal approach in the experimental pigs as it can prevent regrowth of ileal epithelial cells and avoid the complications of conventional enterocystoplasty.Its clinical application deserves further investigations.

After gastrojejunostomy, a small space can occur between the jejunum at the anastomosis site, the transverse mesocolon, and retroperitoneum, which may cause an intestinal hernia. This report presents a rare case of intestinal ischemic necrosis caused by retroanastomotic hernia after subtotal gastrectomy. A 56-year-old male was admitted to Kangwon National University Hospital with melena, abdominal pain, and nausea. His only relevant medical history was gastrectomy due to stomach cancer. Endoscopic findings revealed subtotal gastrectomy with Billroth-II reconstruction and a bluish edematous mucosal change with necrotic tissue in afferent and efferent loops including the anastomosis site. Abdominopelvic CT showed strangulation of proximal small bowel loops due to mesenteric torsion and thickening of the wall of the gastric remnant. Emergency laparotomy was performed. Surgical findings revealed the internal hernia through the defect behind the anastomosis site with strangulation of the jejunum between 20 cm below the Treitz ligament and the proximal ileum. Roux-en-Y anastomosis was performed, and he was discharged without complication. Retroanastomotic hernia, also called Petersen's space hernia, is a rare complication after gastric surgery, cannot be easily recognized, and leads to strangulation.

Meconium peritonitis as a cause of non-immune hydrops in neonates is rarely reported. Here we report such a rare occurrence. In our case, a routine antenatal scan at 25 weeks revealed isolated ascites. By 31 weeks of gestation, all features of hydrops were observed in scans. However, antenatal workup for immune and non-immune hydrops was negative. Subsequently, a preterm hydropic female baby was delivered at 32 weeks. She required intubation and ventilator support. An X-ray revealed calcification in the abdomen suggestive of meconium peritonitis. Ultrasound showed gross ascites, a giant cyst compressing the inferior vena cava, and minimal bilateral pleural effusion. Emergency laparotomy revealed meconium pellets and perforation of the ileum. Double-barrel ileostomy was performed, and the edema resolved and activity improved. The baby was discharged after 3 weeks. Ileostomy closure was done at follow-up. The baby is growing well.

7.Eosinophilic Enteritis Presenting as Massive Ascites after Influenza A Virus Infection in a Young Female
The Korean Journal of Gastroenterology 2019;74(3):163-167
Eosinophilic gastrointestinal disorder (EGID) is an uncommon disease that is accompanied by intestinal eosinophil infiltration without a secondary cause of eosinophilia. Eosinophilic enteritis is a secondary portion of EGID that can present a range of gastrointestinal symptoms according to the affected depth of the intestinal layer. The subserosal type of eosinophilic enteritis presenting as ascites is relatively rarer than the mucosal type. In general, eosinophilic enteritis occurs in patients with food allergies, but its mechanism is unclear. The authors experienced a 29-year-old female patient with a large amount of ascites with diarrhea and abdominal pain. The patient was diagnosed with an influenza A infection one week earlier. Peripheral eosinophilia (absolute eosinophil count: 6,351 cells/mm³) and eosinophilic ascites (97% of white blood cells in the ascites are eosinophil) were present. Abdominal CT revealed a large amount of ascites and edematous changes in the ileum and ascending colon wall. A diagnosis of eosinophilic enteritis was confirmed as eosinophilic ascites by paracentesis, with eosinophil infiltration of the bowel wall by an endoscopic biopsy. The patient's symptoms improved rapidly after using steroids. To the best of the author's knowledge, this is the first report of eosinophilic enteritis with massive ascites after an influenza A virus infection in a Korean adult.

An inflammatory myofibroblastic tumor (IMT) is a solid tumor of unknown etiology frequently affecting children and young adults and commonly affecting the lung or orbital region. We present a case involving a 41-year-old man who had an IMT combined with Mycobacterium tuberculosis infection in the retroperitoneum. He presented with only pain in the right lower abdomen without accompanying symptoms; a retroperitoneal mass was found on computed tomography. The tumor had invaded the end of the ileum and was attached to the omentum, so mass excision could not be performed. The tumor was completely excised surgically and had histological features diagnostic of an IMT. Histologic findings of the omentum were positive for Ziehl-Nielsen staining for acid-fast bacilli and for a positive polymerase chain reaction for M. tuberculosis. The patient had no apparent immune disorder. These findings made this case exceptional because IMTs, which are mostly due to atypical mycobacteria, have been found mainly in immunocompromised patients.

Hypospadias is a congenital malformation of the male genitalia. The reconstructive objectives are to obtain voiding with laminar flow and satisfactory sexual function. Several urethroplasty techniques have been described, but for perineal or revisional cases no single technique has shown robust success. In this study, we describe the expanded use of intestinal flaps for urethral reconstruction and report a peculiar request from a patient to undergo peno-urethral separation after successful hypospadias repair with a free ileum flap. A 51-year-old male patient with perineal hypospadias underwent several urethral reconstructive procedures with poor outcomes. A free ileum flap was attempted as a substitute for the urethra. Following successful reconstruction, separation of the neo-urethra (ileum) from the penile body was performed to address the patient's sexual expectations. A free ileum flap proved to be a reliable urethral substitute in perineal hypospadias reconstruction, with a successful outcome. The peno-urethral separation with the creation of an “accessory penis,” however peculiar, optimized the results in terms of both sexual and urinary function. Anatomical restoration of the urethra and patient-reported expectations are the key to successful hypospadias reconstructive procedures. Sexual function outcomes and the patient's perception of success should not be underestimated, even when urinary function has been restored.

BACKGROUND/AIMS: Consistently defining disease activity remains a critical challenge in the follow-up of patients with Crohn's disease (CD). We investigated the potential applicability of abdominal ultrasonography with color Doppler (USCD) analysis for the detection of morphological alterations and inflammatory activity in CD. METHODS: Forty-three patients with CD ileitis/ileocolitis were evaluated using USCD analysis with measurements obtained on the terminal ileum and right colon. Sonographic parameters included wall thickening, stricture, hyperemia, presence of intra-abdominal mass, and fistulas. Patients were evaluated for the clinical activity (Harvey-Bradshaw Index [HBI]), fecal calprotectin (FC) and C-reactive protein (CRP). The USCD performance was assessed using magnetic resonance enterography (MRE) as a criterion standard. RESULTS: Most measurements obtained with USCD matched the data generated with MRE; however, the agreement improved in clinically active patients where sensitivity, positive predictive value, and accuracy were >80%, considering wall thickening and hyperemia. Complications such as intestinal wall thickening, stricture formation, and hyperemia, were detected in the USCD analysis with moderate agreement with MRE. The best agreement with the USCD analysis was obtained in regard to FC, where the sensitivity, positive predictive value, and accuracy were >70%. The overall performance of USCD was superior to that of HBI, FC and CRP levels, particularly when considering thickening, stricture, and hyperemia parameters. CONCLUSIONS: USCD represents a practical noninvasive and low-cost tool for evaluating patients with ileal or ileocolonic disease, particularly in clinically active CD. Therefore, USCD might become a useful asset in the follow-up of patients with CD.
