RESUMO
BACKGROUND AND AIMS: Non-variceal gastrointestinal bleeding is a common medical emergency. Endoscopic hemostasis is recommended and some patients experienced rebleeding after conventional endoscopic hemostasis. Originally, the purse-string suture (PSS) was employed for lesion closure during endoscopic mucosal resection (EMR). We aimed to learn whether endoscopic PSS is effective in controlling the refractory bleeding. METHODS: We retrospectively collected data of patients who underwent endoscopic PSS for refractory non-variceal gastrointestinal bleeding from 3 hospitals. Clinical success was defined as no recurrent bleeding, and patients were discharged according to medical advice. RESULTS: From October 2017 to May 2024, 36 patients who received PSS treatments were included. 83.3% (30/36) of patients achieved clinical success. In refractory upper gastrointestinal bleeding, the clinical success rate was 81.25% (26/32), and it was 100% (4/4) in lower gastrointestinal bleeding. CONCLUSION: The endoscopic PSS is effective in treating refractory non-variceal gastrointestinal bleeding.
RESUMO
Long non-coding RNA (lncRNA) LINC00467 plays a proto-oncogenic role in non-small cell lung cancer. However, its effect and modulatory mechanism in gastric cancer (GC) are unknown. Thereby, we elucidated the mechanism of LINC00467 in GC. LINC00467 level in GC tissues was assessed by bioinformatic analysis, and clinicopathological parameters from GC patients were collected. The levels of LINC00467, integrin subunit beta 3 (ITGB3), proliferating cell nuclear antigen (PCNA), cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase 1 (PARP1) in tissue samples or treated GC cells were assessed by quantitative real-time polymerase chain reaction (qRT-PCR), fluorescence in situ hybridization (FISH), or Western blot. The viability, proliferation and apoptosis of GC cells were detected by methyl thiazolyl tetrazolium assay, colony formation assay, and flow cytometry. Levels of LINC00467 and ITGB3 were up-regulated in GC, and highly expressed LINC00467 was positively associated with tumor size, differentiation, N stage, and T stage in GC patients. LINC00467 was enriched in cytoplasm of GC cells, and overexpressed LINC00467 promoted the viability and proliferation as well as levels of ITGB3 and PCNA, while suppressing the apoptosis and levels of cleaved caspase-3 and cleaved PARP1 in GC cells. Besides, the effects of shLINC00467 on inhibiting cell viability, proliferation of GC cells and PCNA level and promoting apoptosis as well as levels of cleaved caspase-3 and cleaved PARP1 were all partially reversed by overexpressed ITGB3. Overexpressed LINC00467 enhanced the viability and proliferation but inhibited apoptosis of GC cells via increasing ITGB3 level.
