Background/Aims: Epstein-Barr virus-associated gastric cancers (EBVaGCs) have unique molecular and clinicopathological characteristics. The cyclic GMP-AMP synthase-stimulator of interferon genes (STING) pathway is recently recognized as the critical innate immunity against pathogens and tumors. STING is also a master regulator in the cancer-immunity cycle and targeting STING could synergize with existing immune-checkpoint therapies. However, the role of STING in GC, especially in EBVaGC, and its correlation with programmed death-ligand 1 (PD-L1) remain largely unclear. Methods: We collected 78 cases of EBVaGCs and 210 cases of EBV-negative GC (EBVnGC) from a total of 1,443 cases of GC analyzed by EBV-encoded small RNA in situ hybridization. We investigated STING and PD-L1 expression and their concomitant prognostic value in EBVaGCs and EBVnGCs using tissue microarray and immunohistochemistry. The effects of STING and PD-L1 expression on the overall survival of patients with EBVaGC or EBVnGC were assessed by univariate and multivariate analysis. Results: We found that both STING and PD-L1 exhibited significantly higher expression in the EBVaGCs than that in the EBVnGCs. The expression of STING was positively correlated with that of PD-L1 in EBVaGCs. Simultaneous negative expression of STING and PD-L1, and positive expression of STING were independent prognostic risk factors for EBVaGC and EBVnGC, respectively. Conclusions This is the first prognostic retrospective study of STING and PD-L1 expression and the prognosis among EBVaGC and EBVnGC. The expression and prognostic value of STING and PD-L1 are different in the two types of GCs. STING and PD-L1 are promising prognostic biomarkers and therapeutic targets for EBVaGC and EBVnGC.

Objective:To evaluate the effectiveness and safety of 3.5% lidocaine hydrochloride ophthalmic gel for eye surface anesthesia.Methods:A multicenter, randomized, double-blind, placebo controlled clinical trial was conducted in 10 hospitals in China from August 2018 to April 2019 under the approval of an Ethics Committee of Beijing Hospital (No.2018BJYYEC-014-02). A total of 220 fellow eyes of 220 subjects who received ocular surgery in one eye were actually enrolled according to a same included criteria in different institutes.The 220 eyes were randomly divided into control group and trail group.Two drops of lidocaine hydrochloride gel were dropped at about 5 mm away from corneal limbus at 6 o'clock direction of experimental eye of the trail group, and the blank gel was used in the eyes of the control group in the same way.The pain sensation was assessed with a 0.3 mm toothless micro forceps on conjunctiva within a specified time, and ''pain'' or ''no pain'' was answered by the subjects.The primary effective indexes, namely the number of eyes and percentage of ''no pain'' within 5 minutes following dropping, as well as the secondary indexes including the onset time point of the drug and the duration of anesthesia were recorded and evaluated.Safety evaluation took ocular and system adverse events into account.Results:Within 5 minutes after dropping, ''no pain'' occurred in 104 eyes (94.55%) and 29 eyes (26.36%) in the trail group and control group, respectively, showing a significant difference between the two groups ( χ2=106.948, P<0.001). And there was a significant difference in anesthesia onset time between the trail group and control group (40.0 seconds vs. 300.0 seconds) ( Z=-15.17, P<0.001). The duration of anesthesia was 860.5 (577.5, 1 180.0) seconds in the trail group and 676.0 (280.0, 1 401.0) seconds in the control group, with no statistically significant difference between the two groups ( Z=0.898, P>0.05). The incidence of adverse events in the trail group and control group were 5.45% (6/110) and 4.55% (5/110), respectively, without statistical significance between them ( P=1.000). Conclusions:The 3.5% lidocaine hydrochloride is a safe, effective, easy to use and high-quality surface anesthesia drug for eye surgery.
