Objective To understand the cognition status of medical scientific research ethics review norms among physicians in tertiary hospitals and the factors influencing their awareness.Methods A survey was conducted using a questionnaire.A total of 2 067 questionnaires were distributed to physicians in tertiary hospitals in Henan Province,with an effective response rate of 81.95％.Results(1)Physicians'awareness rate of Regulations on Ethical Review of Biomedical Research Involving Human Subjects reached 69.01％,while that of Opinions on Strengthening Ethical Governance in Science and Technology was only 34.30％.A total of 310 respondents were aware of all six medical research ethics-related regulations.(2)1 153 respondents were familiar with all four basic principles of medical ethics.(3)78.98％of physicians had received training in medical research ethics knowledge.Learning through medical school and special lectures made it easier for physicians to understand medical research ethics knowledge(P＜0.05).(4)The results of binary logistic regression analysis showed that educational level,membership in an ethics committee,and receipt of ethics training significantly influenced physicians'understanding of medical research ethics knowledge(P＜0.05).Conclusion Physicians have low awareness of newly issued medical research ethics review norms,targeted training is needed to enhance physicians'research ethics literacy.

Colon cancer is one of the most common malignant tumors worldwide.When the conventional treatment methods provide survival benefits for patients,their side effects and limitations cannot be ignored.Many traditional Chinese medicines has attracted much attention from scholars at home and abroad because of its anti-tumor advantages of multi-target,multi-pathway and less toxic side effects.Many Chinese medicines and the active components extracted from them,represented by flavonoids,phenols and alkaloids,have played an effective role in anti-tumor.There mechanism is related to inhibiting tumor cell proliferation,inducing apoptosis,regulate autophagy,inhibiting tumor cell invasion and metastasis,inhibiting tumor angiogenesis.In this paper,the mechanism of inhibiting colon cancer by effective components of traditional Chinese medicine in recent years was reviewed in order to provide reference for the clinical treatment of colon cancer.

Objective:To explore the effects of neonatal stimulator of interferon genes (STING) innate immune signaling pathway of HBsAg-positive mothers on non/hypo-response to hepatitis B vaccine (HepB) in their infants.Methods:From November 2019 to June 2022, HBsAg-positive mothers and their infants in the Third People's Hospital of Taiyuan were recruited as the study subjects. The epidemiological and clinical data were collected by questionnaire survey and medical records review. The key molecular proteins of STING innate immune signaling pathway (STING, pIRF3) and immune cells associated with vaccine response (DC, T and B and plasma cells) in neonatal cord blood were detected by flow cytometry. Follow up was conducted for infants for 1-2 months after the full vaccination of HepB. Serum hepatitis B surface antibody (anti-HBs) was detected by chemiluminescence microparticle immunoassay. Unconditional logistic regression model, nomogram and Bayesian network model were used to evaluate the effect of STING innate immune signaling pathway on non/hypo-response to HepB and related factors in infants, and the relationship between various factors.Results:A total of 195 pairs of HBsAg-positive mothers and infants were recruited, the rate of non/hypo-response to HepB in the infants was 12.31% (24/195). High maternal HBV DNA load, low expression of neonatal STING, low expression of pIRF3 and low percentage of plasma cells were risk factors for non/hypo-response to HepB in the infants ( OR=4.70, 3.46, 3.18 and 2.20, all P<0.05). The nomogram constructed by these factors had good predictive efficacy (area under curve=0.81, 95% CI: 0.63-0.83). The results of Bayesian network model showed that the infants with a high maternal HBV DNA load had a higher conditional probability of low STING expression (62.50%) and a higher conditional probability of low pIRF3 expression (58.54%). The conditional probabilities of low expression of DC, T, B and plasma cells were 53.16%, 60.20%, 68.42% and 57.14%, respectively. Conclusion:Maternal HBV DNA might inhibit STING innate immune signaling pathways in infants and immune cells associated with HepB response, resulting in non/hypo-response to HepB in infants of HBsAg-positive mothers.
