ObjectiveTo determine the therapeutic effect of Gegentang granules on a disease-syndrome mouse model combining human coronavirus 229E （hCoV-229E） pneumonia with Hanshi Yidu Xifei syndrome in vivo. MethodMice were randomly divided into normal group， infection group， cold-dampness group， model group， chloroquine phosphate group （0.18 g·kg^-1）， interferon-α2b （IFN-α2b） group （1.83×10⁶ U·kg^-1）， Gegentang granules high-dose and low-dose groups （6.6， 3.3 g·kg^-1） with 10 mice in each group. Cold-dampness environment and hCoV-229E infection were used for modeling， and the general status and lung index of mice in each group were observed. The viral load in lung tissue was detected by real-time fluorescent quantitative polymerase chain reaction （Real-time PCR）， the pathological changes in lung tissue were evaluated by hematoxylin-eosin （HE） staining， the levels of serum gastrointestinal hormones and inflammatory factors in lung tissue were detected by enzyme-linked immunosorbent assay （ELISA）， and the percentage of peripheral blood lymphocytes was detected by flow cytometry. ResultComparing with model group， Gegentang granules could significantly alleviate the physical signs of Hanshi Yidu Xifei syndrome， including listlessness， weakness of limbs， sticky stool， etc. Comparing with model group， Gegentang granules high-dose group significantly reduced lung index， histopathological score of interstitial lung and bronchus， and the level of serum motilin （P<0.05， P<0.01）， two doses of Gegentang granules could significantly increase the level of serum gastrin （P<0.05， P<0.01）， the percentage of CD4⁺， CD8⁺ T lymphocytes in peripheral blood （P<0.05， P<0.01）， and the level of tumor necrosis factor-α （TNF-α） in lung tissue was significantly decreased （P<0.01）， and the level of interleukin-6 （IL-6） showed decreasing tendency. ConclusionGegentang granules has therapeutic effect on model mice. It can improve the appearance and behavior characterization， regulate the level of gastrointestinal hormones， decrease lung index and histopathological score， and possibly play an immunomodulatory role by inhibiting the expression of inflammatory cytokines in lung tissue and restoring the percentage of peripheral blood lymphocytes.

The intervention and prevention of perioperative hypothermia is not only reflected in the technical level, but also reveals the important role of humanistic care in the whole intervention work. If perioperative patients have hypothermia, it is likely to cause a series of complications such as postoperative shivering, which seriously threatens the life safety of patients. Prevention and intervention was based on a comprehensive understanding of the causes and hazards of hypothermia, especially the impact on the lives of the elderly. Effective supervision was implemented in the whole process of operation, such as dynamic monitoring of vital signs including body temperature, followed by room temperature regulation, body temperature protection and preoperative and postoperative psychological nursing. At this time, the sense of responsibility, good humanistic care of medical staff are of positive significance to effectively prevent and reduce the probability of perioperative hypothermia and accelerate the postoperative rehabilitation of patients.
