Objective:To evaluate the incidence of arrhythmias and electrocardiographic (ECG) characteristics in cancer patients treated with immune checkpoint inhibitors (ICIs).Methods:This was a cohort study conducted in the Fourth Hospital of Hebei Medical University. Cancer patients initiating ICIs treatments from November 2020 to September 2022 were included in this study. Baseline 12-leads ECG before ICIs initiation and post-treatment ECG were analyzed. An abnormal ECG was defined as the presence of any of the following changes: sinus arrhythmias, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia, ventricular tachycardia, premature contractions, conduction disorder, and ST-T changes.Results:A total of 87 patients were enrolled, aged 63 (57, 68) years, with 66 (75.9%) males. And 44.8% (39/87) of patients presented with at least one confirmed cardiovascular disease or cardiovascular risk factor at baseline. The incidence of abnormal ECG increased from 31.0% (27/87) at baseline to 65.5% (57/87) after receiving (5.0±2.7) cycles of ICIs treatment ( P<0.001). The incidence of sinus arrhythmias was significantly increased after ICIs treatment (23.0% (20/87) vs. 9.2% (8/87), P=0.023), of which only the incidence of sinus tachycardia was significantly increased (11.5% (10/87) vs. 2.3% (2/87), P=0.039). There was also a significantly increased incidence of ST-T changes after ICIs treatment (31.0% (27/87) vs. 17.2% (15/87), P=0.012), which mainly attributed to the T wave changes (29.9% (26/87) vs. 13.8% (12/87), P=0.001). The incidence of premature contractions was also significantly increased after ICIs treatment (9.2% (8/87) vs. 0, P=0.008). Additionally, compared with baseline, the P wave axis was significantly increased after ICIs treatment ((56.94±21.01)° vs. (52.00±22.69)°, P=0.043). After ICIs treatment, the heart rate was significantly increased ((79.07±15.37) beats/min vs. (75.64±13.37) beats/min, P=0.029). Sokolow-Lyon index ((2.21±0.81)mV vs. (2.33±0.75)mV, P=0.138), QTc interval ((431.44±36.04)ms vs. (428.00±30.05)ms, P=0.415) all showed signs of change after treatment, but did not reach the traditional significant level. Conclusions:The incidence of abnormal ECG is significantly increased after ICIs treatment, especially for sinus tachycardia, premature contractions and T wave changes; the P wave axis and heart rate is also significantly increased after treatment. It is important to perform regular ECG monitoring in patients receiving ICIs treatment.

Objective To describe and analyze the disease burden and its changing trend of liver cancer caused by nonalcoholic steatohepatitis (NASH) in China from 1990 to 2019, and to provide reference for reducing the morbidity and mortality of liver cancer in China. Methods Based on data from the Global Burden of Disease (GBD2019) study, different gender and age groups were selected. The morbidity, mortality, and disability adjusted life year (DALY) rate were used to analyze the disease burden of liver cancer caused by NASH in China from 1990 to 2019. The time trend was analyzed by using the Joinpoint regression model, and the annual percent of change (APC) and annual average percentage change (AAPC) of morbidity, mortality and DALY rate were calculated. Results Compared with 1990, the incidence rate, mortality rate and DALY rate of liver cancer caused by NASH in 2019 decreased by 4.05%, 12% and 25.79%, respectively. Age-standardized morbidity, standardized mortality and standardized DALY rates decreased by 49.50%, 54.72% and 58.45%, respectively. In 2019, the incidence rate, mortality data and DALY rate of liver cancer caused by NASH increased with age, and the highest mortality rate was among people over 85 years old. The average annual change percentage (AAPC) of age-standardized incidence rate, standardized mortality rate and standardized DALY rate of liver cancer caused by NASH from 1990 to 2019 were -2.65% ［95% CI（-3.09%，-2.21 %），P<0.001］, -2.86%［95% CI（-3.34%，-2.38 %），P<0.001］, and -2.91%［95% CI（-3.23%，-2.58%），P<0.001］，respectively. The AAPC of all indexes in males was higher than that in females. Conclusion From 1990 to 2019, the disease burden of liver cancer caused by NASH in China showed an overall downward trend. The AAPC of all indexes in males is higher than that in females, and the elderly population is a high-risk group.

Objective:To explore the safety and efficacy of camrelizumab salvage therapy for extrahepatic recurrent hepatocellular carcinoma with PD-L1 negativity in transplanted liver tissue.Methods:From May 2020 to December 2020, retrospective analysis was performed for 3 cases of camrelizumab salvage therapy for extrahepatic recurrent hepatocellular carcinoma recipients with PD-L1 negative in transplanted liver tissue.Three recipients with extrahepatic recurrence progressed after first/second-line targeted drug therapy.Camrelizumab was given as salvage therapy after normal tissue of ransplanted liver was confirmed as negative for PD-L1 by immunohistochemistry.The safety and efficacy of treatment were observed by monitoring the changes in the levels of alanine aminotransferase, aspartate aminotransferase and bilirubin, the occurrence of complications and the outcome of treatment before and after dosing.Results:During a follow-up period of 1.5 to 15.5 months, no recipients showed acute rejection symptoms such as sharp elevations of transaminase and bilirubin.Headache ( n=1), vomiting ( n=1) and fatigue & hypertension ( n=1) became relieved after treatment.As of February 28, 2022, there were one survivor and two deaths.The fatal causes were tumor progression ( n=1) and thoracic aortic rupture due to esophageal perforation ( n=1). The survival time of recipients was (11-15.5) months and the progression-free survival time (4-6) months. Conclusions:For extrahepatic recurrent hepatocellular carcinoma with PD-L1-negative liver transplantation in normal liver tissue, camrelizumab salvage therapy can control tumor progression to a certain extent and prolong the survival time of recipients.

Objective:To observe the antibacterial effect of Ag +-loaded TiO 2 (Ag -TiO 2) and Ag -TiO 2 coated endotracheal tube (ETT) on the bacterial biofilm (BF) of Staphylococcus aureus. Methods:2, 3-bis-(2-methoxy- 4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) colorimetric method was used to detect minimal inhibitory concertation (MIC) of Ag-TiO 2 for inhibition of BF of Staphylococcus aureus. The Ag -TiO 2 coated ETT were prepared, and divided into 11 mg/L, 8 mg/L, 5 mg/L, 2 mg/L and 0 mg/L ETT group, according to the concentration gradient, then impregnated in the liquid with Staphylococcus aureus at a concentration of 1.0×10 9cfu/L. The influence of antibacterial coated ETT on the formation of Staphylococcus aureus BF was determined by detecting the colonies of bacteria and BF on the ETT. Results:Ag-TiO 2 had a significant inhibitory effect on Staphylococcus aureus BF in a concentration -dependent manner, and its MIC was 10 mg/L. Ag -TiO 2 coated ETT has significant anti -Staphylococcus aureus BF effect, and the higher the concentration, the stronger the effect. The absorbance ( A) values of Ag -TiO 2 5 mg/L, 8 mg/L, 11 mg/L ETT groups were significantly lower than that in control group (0.176±0.004, 0.147±0.002, 0.094±0.002 vs. 0.267±0.045, all P < 0.05). The inhibitory rates of Ag -TiO 2 2 mg/L, 5 mg/L, 8 mg/L ETT groups were increased gradually, and 11 mg/L Ag -TiO 2 coated ETT group had the highest inhibitory rate for BF, the inhibitory rates were 6.4%, 34.1%, 44.9% and 64.8%, respectively. Conclusion:Both Ag-TiO 2 and Ag-TiO 2 coated ETT have significant inhibitory effects on Staphylococcus aureus BF.
