Effect and mechanism of needleless transcutaneous neuromodulation on gastrointestinal function after pancreaticoduodenectomy.

Background: Gastrointestinal motility disorders tend to develop after pancreaticoduodenectomy (PD). The objectives of this study were: (1) to investigate the impact of needleless transcutaneous neuromodulation (TN) on the postoperative recuperation following pancreaticoduodenectomy (PD), and (2) to explore the underlying mechanisms by which TN facilitates the recovery of gastrointestinal function after PD.

Methods: A total of 41 patients scheduled for PD were randomized into two groups: the TN group ( = 21) and the Sham-TN group ( = 20).

Mixed serous-neuroendocrine neoplasm of the pancreas: A case report and review of the literature.

Background: Pancreatic mixed serous-neuroendocrine neoplasms (MSNNs) are mixed tumors containing two components with different pathologies, namely, pancreatic serous cystic neoplasm (PSCN) and pancreatic neuroendocrine tumor (PanNET). For MSNNs, diffuse PSCN involving the whole pancreas is extremely rare, with only eight previous case reports.

Case Summary: A 45-year-old Chinese woman, with a free previous medical history and no obvious symptoms, was found to have a pancreatic neoplasm and admitted to our hospital for further diagnosis in March 2018.

HRD1 suppresses the growth and metastasis of breast cancer cells by promoting IGF-1R degradation.

HRD1 (3-hydroxy-3-methylglutaryl reductase degradation) is an E3 ubiquitin ligase. We found that HRD1 was significantly downregulated in 170 breast cancer tissues. Low tumoral HRD1 expression was correlated with clinicopathological characteristics and a shorter survival in breast cancer patients.

Multiple carcinosarcomas of the esophagus and stomach.

Carcinosarcoma is an uncommon biphasic malignant neoplasm consisting of both carcinomatous and sarcomatous components. We report a case of an 84-year-old male with multiple carcinosarcomas occurring in the esophagus and stomach. Endoscopically, a bulky pedunculated polypoid lesion was observed in the middle of the esophagus and a huge discoid lesion in the lesser curvature.

Endoscopic polypectomy: a promising therapeutic choice for esophageal carcinosarcoma.

Esophageal carcinosarcoma is a rare malignant tumor composing of both carcinomatous and sarcomatous elements. Endoscopic therapy is less invasive and may represent an alternative to esophagectomy for superficial esophageal carcinosarcoma. Here, we report a 61-year-old male who was diagnosed as esophageal carcinosarcoma and underwent endoscopic polypectomy with well tolerance and favorable prognosis.
