This study aimed to evaluate the effect of postoperative use of octreotide on the outcomes after PD.Methods: This is a prospective randomized controlled trial for postoperative use of octreotide in patients undergoing PD. Patients with soft pancreas and pancreatic duct < 3 mm were randomized to 2 groups.Group I did not receive postoperative octreotide. Group II received postoperative octreotide. The primary end of the study is to compare the rate of POPF.Results: A total of 104 patients were included in the study and were divided into two randomized groups.There were no significant difference in overall complications and its severity. POPF occurred in 11 patients(21.2%) in group I and 10(19.2%) in group II, without statistical significance(P = 0.807). Also, there was no significant differences between both groups regarding the incidence of biliary leakage(P = 0.083), delayed gastric emptying(P = 0.472), and early postoperative mortality(P = 0.727).Conclusions: Octreotide did not reduce postoperative morbidities, reoperation and mortality rate. Also, it did not affect the incidence of POPF and its clinically relevant variants.展开更多

METHODS:The improved Aho method was used to prepare SAP rat models.These rats were then randomly divided into a sham-operated group(n=45),a model control group(n=45), baicalin-treated group(n=45)and octreotide-treated group (n=45).Based on the difference in time points after operation, these groups were subdivided into 3,6 and 12 hour subgroups (n=15).At the corresponding time point after operation,the mortality rate of rats was recorded,and then the rats were humanely killed to take samples of multiple organs that were subsequently examined for pathological changes under light and electron microscopy. RESULTS:At 12 hours after operation,the mortality rate of rats in the baicalin-and octreotide-treated groups was lower than that in the model control group(P【0.05).Compared to the model control group,the pathological changes and pathological scores in the baicalin-and octreotide-treated groups were mitigated and relieved to varying degrees.The pathological changes under electron microscopy were also improved.CONCLUSIONS:Both baicalin and octreotide show good protective effects on multiple organs of SAP rats.Baicalin as a new drug has good prospects in the treatment of SAP.展开更多

Male nude mice were subcutaneously implanted with LCI-D20 tumor tissuesfor tumor xenograft studies. Microvessel density in CD34-stained tumor sections was analyzed byimmunohistochemical SP method.RESULTS: Tumor tissues from LCI-D20 implanted into the corneal micropocket induced angiogenesis.When animals received systemic octreotide treatment, angiogenesis response in the cornea of mice wasmoderate, the appearance of vascular buds was delayed, and the new capillaries were sparse and grewslowly. Compared with the control group, the neovascularization induced by HCC in the cornea of micewas markedly inhibited on day 7, 9, 12, 15, 18 and 21 after implantation in the octreotide-treated group(P【0.05). Systemic administration of octreotide produced a significant suppression of the growth ofLCI-D20. Immunohistochemical studies of tumor tissues revealed decreased microvessel density in theoctreotide-treated animals as compared with the controls (21.7±4.27 versus 31.8±3.87, P【0. 01).CONCLUSION: Somatostatin analogue octreotide is able to inhibit angiogenesis induced by HCC invivo and may provide a new approach to the treatment of HCC.展开更多
