Objective:To describe the characteristics and analyze risk factors for surgical items count near-miss errors stemming from the self-incident reports of staff nurses from operating room, to reduce the risk of counting surgical items and prevent the occurrence of the relative adverse events.Methods:This was a retrospective study. Used the self-made checklist to retrospect the surgical items count errors, relative characteristics and reasons from the operating room nurses of Department of Anesthesiology, Shandong Provincial Hospital Affiliated to Shandong First Medical University reported from January 2017 to December 2021. Grey Relational Analysis was used to analyze and identify the risk elements.Results:A total of 98 surgical items count near-miss errors were reported by nurses.The unclear items were mainly classified into 6 categories, of which 52.04% (51/98) were disposable surgical items, 24.49% (24/98) were fine parts of surgical instruments, 14.28% (14/98) were implants, 5.10% (5/98) were electrosurgical instruments, 3.06% (3/98) were power systems, and 1.02% (1/98) were medical lasers; the disposable surgical items were the highest risk of surgical items count near-miss errors (non-standard behaviors of surgeons ξ 1=0.333); among the 9 risk factors, non-standard behaviors of surgeons ( r1 = 0.673), instrument nurses improper operation ( r4 = 0.691) and surgeons errors ( r2 = 0.693) were the most important influence factors. Conclusions:Analyzing the possible system risk factors resulting from the near-miss error could be a useful method for nurses to generate hierarchical risk-control strategies and improve surgical items count safety for patients. This com prerent the occurrence of adverse events.

Objective:To investigate the efficacy and safety of programmed death-1 (PD1) inhibitor combined with transcatheter arterial chemoembolization (TACE) in the treatment of huge primary liver cancer.Methods:From June 2016 to December 2019, the clinical data of 31 patients with huge primary liver cancer enrolled in the Central Hospital of Lishui were retrospectively collected and analyzed. The tumor size ranged from 10.1 to 18.8 cm, with an average of (14.2±2.3) cm. The patients were divided into TACE group (TACE treatment, 18 cases) and combined group (one week after TACE, patients receiving a dose of 200 mg PD1 inhibitor administration every 21 days, 13 cases), according to whether patients receiving PD1 inhibitors. The patients were followed up. The disease control rate (DCR) were compared between the two groups using Mann-Whitney U test. The median overall survival (OS) and progression free survival (PFS) were calculated by Kaplan-Meier method. Results:The DCR in combined group (53.8%, 7/13) was higher than that in TACE group (22.2%, 4/18), and the difference was statistically significant ( Z=-2.13, P=0.04). The median PFS (5.0 months) in combined group was longer than that in TACE group (3.0 months), the difference was statistically significant (χ2=4.39, P=0.04). The median OS (15 months) in combined group was longer than that in control group (9 months), and the difference was statistically significant (χ2=5.51, P=0.02). Conclusion:The combine PD1 inhibitors with TACE is an effective and safe therapy for huge primary liver cancer.

OBJECTIVE: To develop a fiber Raman endoscopic probe that can be integrated in a gastroscope and evaluate its value in the diagnosis of gastric cancer.
