Objective To establish a pancreatic cancer model in Sprague Dawley(SD) rats,and to study the distribution and the counts of myofibroblast(MF) in pancreatic cancer and non-cancerous pancreatic tissues.MethodsDirectly implanted DMBA into pancreas parenchyma of SD rats and established TSA intervening group and control group. The carcinogenesis of rats executed within 3～5 months were inspected by HE stain and microscopy for pathomorphological changes.Myofibroblast(MF) was stained by Heidenains method. Results (1)The prevalence of pancreatic cancer in experimental group was 48.7%(18/37), including 17 pancreatic ductal adenocarcinoma and 1 fibrosarcoma. The prevalence of pancreatic cancer in intervering group was 33.3%(12/36), including 11 pancreatic ductal adenocarcinoma and 1 fibrosarcoma. The maximal diameters of tumor mass of experimental group was higher than that of intervering group (P

AIM: To discuss the impacts of pterygium excision combined with low-temperature plasma radiofrequency ablation and autologous conjunctival flap transplantation on tear film function, visual function, and recurrence rate in patients with pterygium.METHODS: A retrospective study was conducted on patients with pterygium who underwent surgery at Jiangyin Hospital of Traditional Chinese Medicine from March 2021 to January 2024. The patients were divided into two groups based on the surgical methods: the excision group with 50 cases(50 eyes)and the combined group with 51 cases(51 eyes). The excision group underwent pterygium excision, while the combined group received low-temperature plasma radiofrequency ablation and autologous conjunctival flap transplantation in addition to the excision. The tear film function [Schirmer's test(SⅠt), tear film break-up time(BUT)], visual quality, therapeutic effect, incidence of complications within 1 a, and recurrence rate were compared between the two groups before and after treatment.RESULTS: The general data of the two groups were comparable(P>0.05). After treatment, the SⅠt and BUT in the combined group were greater than those in the excision group(both P<0.001), while the corneal astigmatism and uncorrected visual acuity were lower than those in the excision group(both P<0.001). The initial treatment efficiency in the combined group(92%)was higher than that in the excision group(76%). Within 1 a, the recurrence rate(8% vs 22%)and complication rate(6% vs 24%)in the combined group were both lower than those in the excision group(both P< 0.05).CONCLUSION: The union of pterygium excision, low-temperature plasma radiofrequency ablation, and autologous conjunctival flap transplantation is beneficial for improving the efficacy, visual acuity, tear film function, and reducing recurrence rate in patients with pterygium.
