There is still a lack of experience in the perioperative strategy for esophageal cancer patients in China during the epidemic of COVID-19. In December 2022, a 59-year-old male patient with esophageal cancer was admitted to our department. He received 2 cycles of neoadjuvant therapy before surgery, and developed COVID-19 perioperatively. After treatment, the infection symptoms of the patient were improved, and the postoperative recovery was satisfactory.
Objective To measure the expression level of Myc-interacting zinc finger protein-1 (MIZ1) in peripheral blood mononuclear cells (PBMC) of patients with severe and non-severe community-acquired pneumonia (CAP) and its relationship with inflammatory factors. Methods Thirty-six CAP patients from Beijing Chaoyang Hospital from April 2018 to June 2019 were enrolled in this study. MIZ1 mRNA level in PBMC were measured by reverse transcriptase-quantitative polymerase chain reaction. The levels of interleukin (IL)-6, IL-8, IL-10, and interferon-α in the serum of patients were measured by enzyme-linked immunosorbent assay. The levels of MIZ1 mRNA and inflammatory factors were compared between the severe CAP patients and the non-severe CAP patients. Results Compared with non-severe CAP patients, the MIZ1 mRNA level in the PBMC of severe CAP patients was lower (P<0.05) than non-severe group. Receiver operating characteristic (ROC) curve of the expression level of MIZ1 in PBMC was calculated according to whether CAP was severe or non-severe, and the area under ROC curve was 0.731 (P=0.018). Spearman correlation analysis showed that MIZ1 mRNA was negatively correlated with IL-10 level in the severe CAP patients (Spearman correlation co-efficient was –0.620, P<0.05). Conclusions MIZ1 may indicate the severity of CAP. MIZ1 may affect IL-10 so as to play a role in inflammation regulation.
Objective To explore the effectiveness of passive immunization of fetus via mother on preventing the transmission of HBV from mother to infant. Methods A prospective randomized controlled study was designed. Fifty-two HBeAg positive pregnant women were randomly allocated to two groups, of which 28 women were allocated to trial group, and injected with 200 IU of hepatitis B immune globulin (HBIG) for 1 injection at the 28th, 32nd and 36th weeks of pregnancy respectively, 24 women allocated to control group were given no injection of HBIG. The samples of cord blood from the newborns in two groups were collected and tested for HBeAg and HBV-DNA by ELISA and FQ-PCR. Results The rates of HBeAg positive in the newborns were 21.4% in trial group, 79.2% in control group. There was statistically significant difference between two groups ( χ2=17.26, Plt;0.01, RR=0.27). The rates of HBV-DNA positive in newborns were 25.0% in trial group, 83.3% in control group, showing statistically significant difference between the two groups (χ2=17.62, Plt;0.01, RR=0.30). In the trial group, there were 21 newborns with HBV-DNA negative, 7 with HBV-DNA positive. HBV-DNA quantities were significantly lower in 7 newborns than in their mothers (T=28, P=0.02, Wilcoxon test). Conclusions Multiple injections of HBIG to pregnant women with HBeAg positive before labor could greatly reduce mother-infant transmission of HBV.
