AIM:To assess the clinical efficacy of 5-fluorouracil(5-FU)and bandage contact lens in the pterygium excision combined with autogenous limbal stem cell transplantation(ALSCT)in treating patients with pterygium.METHODS:Random controlled clinical trial. A total of 71 patients(71 eyes)of pterygium who treated at the department of ophthalmology in Qinhuangdao Haigang Hospital between May 2021 and November 2022 were included. They were divide into three groups, including 23 eyes received pterygium excision combined with ALSCT in group A, 24 eyes that were administered with 5-FU intraoperatively and postoperatively in group B, and 24 eyes that received both bandage contact lens and 5-FU in group C. Furthermore, comfort levels at 1, 3, 7, 14d postoperatively, corneal epithelial healing at 1, 3, 7, 14d and 1mo postoperatively, treatment outcomes and complications at 3～6mo postoperatively were compared among the three groups of patients.RESULTS:The comfort levels at 1, 3 and 7d postoperatively and corneal healing at 1 and 3d postoperatively of the group C were better than those of the groups A and B. There were no statistical significant differences in the comfort levels at 14d after surgery and corneal healing at 14d and 1mo after surgery among the three groups of patients. Over a 3～6mo follow-up period, group A experienced recurrence in 3 eyes, group B had 1 recurrence, while group C had no recurrence. There were no statistically significant differences in complication rates among the three groups of patients.CONCLUSIONS: The application of 5-FU combined with bandage contact lens can enhance postoperative comfort levels, promote corneal epithelial healing, and improve the success rate in pterygium excision combined with ALSCT.

Objective To analyze the CT findings of tuberculous lymphadenitis in parotid gland, so as to improve the diagnostic accuracy of tuberculosis of parotid gland. Methods Nine cases with tuberculous lymphadenitis in parotid gland confirmed by surgical pathology and acid-fast bacilli after preoperative spiral CT plain scan and two phases dynamic enhancement scan were retrospectively analyzed.Imaging findings of CT were reviewed and compared with surgical pathology. Results Seven of the 9 cases of tuberculosis of the parotid gland occurred in the left side, and 2 in the right side, and superficial lobe involvement occurred in 8 cases and deep lobe in 1 ease. The lesion was classified as tumour type (8 cases)and infiltration type (1 case). In tumour type, the number of lesion was from 1 to 4, and the size was from 2.7 to 5.3 cm in diameter. One case of infiltration type measured 3.4 cm in diameter. On CT plain scan,the lesions showed homogeneous slight high-density with regular edge in 5 cases and irregular low-density in 4 cases, and 2 of them with partly blurred edge. On CT enhanced scan, uniform moderate enhancement was seen in 3 cases, circular enhancement in 4 cases, inhomogeneous enhancement in 1 case, and lace-like enhancement in 1 case. Local infiltration occurred in 6 cases. Lymphadenovarix in the same side of lesion occurred in 2 cases. Conclusion CT findings of tuberculous lymphadenitis in parotid gland present diversification, which correlate well with pathological changes. Understanding of characteristic CT findings of tuberculous lymphadenitis in parotid gland is helpful for differential diagnosis, but final diagnosis still depends on pathology and acid-fast baeilli.

Objective To investigate the expression of CD44v3 and VEGF-C in human gastric cancers and the clinical significance. Methods The expression of CD44v3 and VEGF-C was detected by immunohistochemistry SP method in 92 gastric cancer tissues. Results Positive immunohistochemical stain for CD44v3 was identified in 27.2% of gastric cancer tissues. There was no correlation found among the expression of CD44v3 with sex, location,depth of invasion, WHO type, Lauren type as well as distant metastasis (all P ＞ 0. 05 ). The expression of CD44v3 was positively correlated with lymph node metastasis and tumor differentiation( all P ＜ 0. 05 ). Positive immunohistochemical stain for VEGF-C was identified in 48.9% of gastric cancer tissues. There was no correlation found among the expression of VEGF-C with sex,location, tumor differentiation, depth of invasion, WHO type, as well as distant metastasis ( all P ＞ 0. 05 ). The expression of VEGF-C was positively correlated with lymph node metastasis and Lauren type ( all P ＜0. 05). Cox-Regression reflected that only the lymphatic metastasis situation correlated with the life ratio( P =0. 015). Conclusion The expression of CD44v3 and VEGF-C could suggest the progression and metastatic potential value of gastric cancer,but didnt correlate with the life ratio. There was no cooperation between CD44v3 and VEGF-C in promoting gastric cancer metastasis.
