The purpose of this study is to assess the value of early abdominal non-enhanced computed tomography (NECT) in developing strategies for treating acute gallstone pancreatitis (AGP). AGP patients underwent NECT within 48 h after symptom onset to determine the presence of peripancreatic fluid collection, gallstones, and common bile duct stones. Patients with mild AGP who had neither organ failure by clinical data nor peripancreatic fluid collection by NECT (classified as grade A, B, or C based on the Balthazar CT grading system) were randomized to undergo an early laparoscopic cholecystomy (ELC; LC performed within 7 days after a pancreatitis attack, without waiting for symptom resolution) or late laparoscopic cholecystomy (LLC; LC performed ≥ 7 days following an attack, with the patient being completely free of AGP symptoms). The study enrolled 102 patients with mild AGP defined by clinical data and NECT. NECT was 89.2 % and 87.8 % accurate in detecting gallbladder stones and CBD stones, respectively. Totals of 49 and 53 patients were assigned to an ELC and LLC group, respectively. All patients in both groups were cured, no LC-related complications occurred, and no case of AGP increased in severity following LC. The mean lengths of hospital stay and LC operation time were significantly shorter in the ELC group than the LLC group (P

CD39/ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1) is a cell surface-located, rate-limiting enzyme in the generation of adenosine, and plays a crucial role in tumor development. We examined co-expression of CD39 and CD8in gastric cancer (GC) and showed that the expression of CD39 and CD8 increased significantly in tumor tissues compared to paired peritumor tissues. The expression of tumoral CD39 (tCD39), but not tumoral CD8 (tCD8), was related to overall survival. Furthermore, the CD39(+)/CD8(+) ratio was associated with poor prognosis in resected GC patients. Taken together, our data indicate that highCD39 expression and high tCD39(+)/CD8(+) ratio in GC is a predictor of poor prognosis for GC patients after radical resection. Moreover, CD39 could serve as a potential target for cancer immunotherapy.

Ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1), also known as cluster of differentiation (CD)39, is the rate-limiting enzyme in the generation of immunosuppressive adenosine and is important in tumor progression. The present study evaluated the expression of CD39+ and CD39+ forkhead box P3 (FoxP3)+ regulatory T (Treg) cells in gastric cancer (GC), and determined their prognostic roles in patients with GC following radical resection. It was observed that CD39 was expressed at significantly higher rates in tumor tissues as compared with paired peritumoral tissues. Overexpression of tumor CD39 was correlated with overall survival (OS). Furthermore, CD39 expression in GC tissues exhibited a prognostic role in OS. The CD39+ FoxP3+/FoxP3+ ratio in tumor tissues was higher than that in paired peritumoral tissues, and CD39+ FoxP3+ Treg cells were a better prognostic indicator than FoxP3+ Treg cells for OS. Collectively, our study indicates that overexpression of CD39 in GC is a predictor of poor outcome for GC patients following radical resection. CD39+ FoxP3+ Treg cells are a potential target for cancer immunotherapy.
