Objective To investigate the effects of advanced glycation endproducts (AGEs) on proliferation of pericytes of bovine retinal capillary vessels and expression of transforming growth factor ?(TGF-?). Methods [WTBZ]The proliferation of pericytes detected by methyl thiazolyl tetrazolium (MTT) colorimetric assay, cellular cycle of pericytes was analyzed by flow cytometry was used to analyze cell, and TGF-? protein expression of pericytes was observed by immunofluorescent staining. Results AGEs inhibited the proliferation of pericytes of bovine retinal capillary vessels, stopped the cellular cycle of pericytes in synthesis phase (S phase), increased the number of apoptotic cells obviously (P

This paper reviewed the clinical data of a patient with primary abdominal cocoon syndrome, situs inversus totalis and bilateral cryptorchidism admitted to our hospital in March 2021, and discussed the clinical characteristics of the disease based on the literature. This case is relatively rare, and all three diseases involve congenital abnormalities that may lead to developmental disorders in the embryo. The clinical manifestations of abdominal cocoon syndrome lack of specificity, preoperative diagnosis is difficult, often accompanied by partial dysplasia, so it is necessary to improve the awareness of preoperative differential diagnosis.

Objective To clarify the clinical features of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) with minor endoscopic abnormalities. Methods The clinical data of 6 patients with MEITL characterized by minor endoscopic abnormalities in Peking Union Medical College Hospital from 2012 to 2016 were retrospectively analyzed, including clinical manifestations, endoscopic, pathological features, medications and prognosis. Results Five out of 6 patients were male, with an average age of 61.2 years old. The median disease duration was 4.5 months. All patients initially presented with diarrhea without specific findings for serologic testing. CT enterography showed continuous intestinal lesions, including symmetric thickening of the bowel wall, abnormal hyperenhancement of mucosal surface and lymphadenopathy. Endoscopic appearances were only mildly abnormal, including mucosal swelling, atrophy of villus, mosaic sign and shallow ulcers. Histopathologic findings revealed massive small to medium sized T lymphocytes infiltration with positive expression of CD3 and CD8. Chemotherapy and palliative treatment were administrated after diagnosis. Conclusions Clinical presentations of MEITL are non-specific with minor endoscopic abnormalities. Therefore, biopsy is indispensable for patients with a relatively normal endoscopic result.

A 60-year-old man presented with severe watery diarrhea for 2 months complicated with weight loss and acute kidney injury.He did not respond well to antidiarrheal medicines,empirical antibiotics and dietary exclusion of gluten or even complete bowel rest.The final diagnosis of autoimmune enteropathy (AIE) was made based on histopathologic findings of endoscopic biopsy from duodenal mucosa after excluding neoplastic disease,inflammatory bowel disease,and infectious diarrhea,etc.Chronic diarrhea and oliguria alleviated after the administration of corticosteroids.

To explore the effectiveness of "near peer learning" (NPL) in the electromyography(EMG)teaching module for neurology residents.
