The use of selective splenic vascular control in laparoscopic splenic vessels and spleen preservation distal pancreatectomy.

Background: In the process of laparoscopic splenic vessels and spleen preservation distal pancreatectomy (LsvSPDP), because the splenic blood vessels have many small branches, how to safely separate the splenic blood vessels from the pancreas has always been the focus and difficulty of this operation. Many cases were switched to laparotomy, or the Warshaw method due to the inability to control bleeding during the separation of the splenic blood vessels. Therefore, we tried to use the selective splenic vascular control method when separating the splenic blood vessels to observe its effect on the conditions of the surgical patients during and after the operation.

Narrative review of intraductal papillary mucinous neoplasms: pathogenesis, diagnosis, and treatment of a true precancerous lesion.

Objective: Although considerable progress has been made in our understanding of intraductal papillary mucinous neoplasm (IPMN) of the pancreas, there are still some problems to be solved.

Background: IPMN is one of the most important precancerous lesions of pancreatic cancer, but the relationship between IPMN and pancreatic cancer, and the specific mechanism of the development from IPMN to invasive carcinoma, remain to be explored in depth. With the development of imaging, the detection rate of IPMN has been greatly improved.

Title: Developmental validation of Y-SNP pedigree tagging system: A panel via quick ARMS PCR.

The Y chromosomal short tandem repeats (Y-STRs) have been used widely to establish paternal relatedness and examine sub-structures in different geographical regions. However, the applications of Y-STRs showed their limitations when it comes to resolving the complicated relationships within close relatives or among unrelated individuals from different geographic areas. Here, we overcome these limitations by introducing a new strategy for Y-SNP multiplex typing using rapid ARMS (amplification-refractory mutation system) PCR.

Concurrent hearing and genetic screening in a general newborn population.

Newborn hearing screening is not designed to detect delayed-onset prelingual hearing loss or aminoglycoside-antibiotic-induced ototoxicity.

A case report of huge perirenal liposarcoma associated with renal cell carcinoma and reviews of three previous cases.

Retroperitoneal liposarcoma (RPLS) is a rare malignant tumor yet with a high recurrence rate. It is mostly observed in limbs and during retroperitoneal clearance, and accounts for nearly 40% of all adult retroperitoneal soft tissue sarcomas [1]. Renal cell carcinoma (RCC) is a common cancer developed in urinary system and its occurrence rate accounts for 3% of whole body malignant tumors [2].

CCL18 promotes epithelial-mesenchymal transition, invasion and migration of pancreatic cancer cells in pancreatic ductal adenocarcinoma.

CCL18 is a chemokine that is primarily expressed in monocytes, macrophages and immature dendritic cells and plays a crucial role in immune and inflammation responses. Recently, CCL18 was found to play pivotal roles in the development of several kinds of cancers, but its expression status and role during the tumorigenesis of pancreatic cancer remain unknown. In this study, we performed immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) to evaluate the expression of CCL18 in human pancreatic ductal adenocarcinoma (PDAC) tissues and preoperative serum, respectively.

Soluble a‑proliferation‑inducing ligand (sAPRIL), a novel serum biomarker predicting the recurrence and metastasis of pancreatic adenocarcinoma after surgery.

Pancreatic adenocarcinoma (PA) is a leading cause of adult cancer mortality, and surgery is still the best available treatment strategy. However, PA can recur at any time and has limited prognosis. It is therefore necessary to explore novel serum biomarkers of PA to allow the early diagnosis of PA.
