RESUMEN
Objective Based on the epidemic situation of hepatitis B and liver cancer patients in Nantong from 2019 to 2022, to analyze the trend of hepatitis B virus DNA (HBV-DNA) changes and provide theoretical basis for the prevention and treatment of hepatitis B and liver cancer. Methods The data of patients with hepatitis B and liver cancer in Nantong Cancer Hospital were collected, and the general data, the time of infection with hepatitis B and the results of quantitative HBV-DNA test were statistically analyzed. Results A total of 487 patients with hepatitis B and liver cancer were collected, including 395 males and 92 females. Among them, patients aged 51-60 were the most common, accounting for 28.34%, followed by those aged 41-50 and 61-70, accounting for 23.00% and 21.56% respectively. In addition to 84 patients with unknown infection time, most of the patients with hepatitis B infection time distributed in 11 to 20 years, followed by 21 to 30 years and 1 to 10 years. Except for 126 patients with unknown levels of HBV DNA, the positive rate of HBV DNA in 361 patients was 64.82%. Between 2019 and 2022, except for patients with unknown levels of HBV-DNA, the proportion of patients with HBV-DNA<500 copies/mL showed an upward trend, while the proportion of patients with HBV-DNA (103-106) copies/mL showed a downward trend. Conclusion Sex and the time of infection with hepatitis B are high risk factors for hepatitis B liver cancer. Most patients with liver cancer are positive for HBV-DNA, which needs to be tested regularly to guide antiviral treatment.
RESUMEN
Objective To compare the influence of general anesthesia and spinal anesthesia on the mortality in rats with fat embolism.Methods Three hundred and seventy five rats were randomly assigned to receive general anesthesia (group GF,n=125),spinal anesthesia (group SF,n=125),or no anesthesia (group F,n=125).Rats were injected with a half lethal dose of fat from caudal vein 20 min after anesthesia induction. The mortality was recorded at 2,8,12,and 24 h after fat injection,respectively.Results The mortality was lower in group GF than those in groups SF and F (P0.05),while there was no statistical difference between group SF and group F.Conclusion The mortality in rats with fat embolism under general anesthesia was lower than that under spinal anesthesia.
