Abstract
Brunner's gland cysts are rare, benign lesions of the duodenum usually seen as incidental, polypoid or cystic lesions of the duodenum. We present a series of 25 cases of Brunner's gland cyst, the largest case series to date. All the cases were identified during endoscopic assessment for unrelated causes. The mean age of the patients was 66.2 years and the sex ratio was approximately equal. Most were detected as a small (3-10 mm) polypoid lesion in the second part of the duodenum, away from the ampulla. Most of the cysts were unilocular and all were lined by undulating, cytologically bland cuboidal to columnar cells with clear cytoplasm and small, basal nuclei. No mitotic activity or proliferative activity was seen. No recurrence was noted, despite incomplete removal in many cases. We agree with the hypothesis that Brunner's gland cysts are likely to be caused by local obstruction to the draining duct of Brunner's glands.

Abstract
Wild-type p53-induced phosphatase 1 (Wip1) is currently believed to be a promising drug target for cancer therapy. Our recent studies showed that deletion of Wip1 remarkably promoted neutrophil inflammatory response. Whether Wip1 is involved in the regulation of inflammatory bowel disease is unknown. In the present study, we found that Wip1 knockout (KO) mice were more susceptible to colitis induced by dextran sulphate sodium (DSS) than wild-type mice as substantiated by the lower mouse survival ratio, rapid bodyweight loss, increased disease activity index, shorter colon length, and more severe pathology of colons in Wip1KO mice. Using full bone marrow chimera mouse models, we demonstrated that Wip1 intrinsically controls inflammatory response of immune cells. Deletion of IL-17 (Wip1/IL-17 double KO mice) significantly rescued the pathology in Wip1KO mice. Neutrophils of DSS-treated wild-type and Wip1KO mice expressed significantly higher IL-17. After adoptive transfer of sorted Wip1KO or double KO neutrophils into IL-17KO mice, mice receiving double KO neutrophils were more resistant to DSS-induced colitis than mice receiving Wip1KO neutrophils. These data collectively indicate that Wip1 modulates host sensitivity to colitis by intrinsically regulating immune cells. The enhanced IL-17 expression in neutrophils contributed to the increased sensitivity and severity of colitis in Wip1KO mice. Thus, Wip1 may be used as a drug target to treat colitis.

Abstract
Brunner's gland cysts are rare benign lesions that are mainly observed in the first and the second regions of the duodenum. Patients with Brunner's gland cyst demonstrate no specific symptoms. The present study reports the case of a patient with Brunner's gland cyst located in the duodenum in combination with a gastrointestinal stromal tumor (GIST) in the same region. To the best of our knowledge, the present study reports the first case of Brunner's gland cyst with GIST. A 58-year-old female patient was referred to Tianchang Hospital of Traditional Chinese Medicine (Tianchang, China) with a one-month history of upper abdominal discomfort, diarrhea and recurrent vomiting following the intake of food. Upper gastrointestinal endoscopy and a computed tomography scan revealed the presence of a round, cystic-like lesion with internal low density located within the duodenum. Pathological examination revealed that the cyst measured 0.3 cm in diameter and was consistent with a diagnosis of Brunner's gland cyst. Histopathology revealed that the cyst possessed characteristics of GIST. The patient underwent surgical exploration and tumor resection, and was discharged 2 weeks post-surgery. During the 12 month post-operative follow-up period, the outcome of the patient was good. This case study of Brunner's gland cyst combined with GIST enriches the present literature and promotes better understanding of the two diseases. Further investigation is required to explain the mechanism and association between the two rare diseases.
