RESUMEN
BACKGROUND: The global pandemic of coronavirus disease 2019 pneumonia poses a particular challenge to the emergency surgical treatment of elderly patients with high-risk acute abdominal diseases. Elderly patients are a high-risk group for surgical treatment. If the incarceration of gallstones cannot be relieved, emergency surgery is unavoidable. CASE SUMMARY: We report an 89-year-old male patient with acute gangrenous cholecystitis and septic shock induced by incarcerated cholecystolithiasis. He had several coexisting, high-risk underlying diseases, had a history of radical gastrectomy for gastric cancer, and was taking aspirin before the operation. Nevertheless, he underwent emergency laparoscopic cholecystectomy, with maintenance of postoperative heart and lung function, successfully recovered, and was discharged on day 8 after the operation. CONCLUSION: Emergency surgery for elderly patients with acute abdominal disease is safe and feasible during the coronavirus disease 2019 pandemic, the key is to abide strictly by the hospital's epidemic prevention regulations, fully implement the epidemic prevention procedure for emergency surgery, fully prepare before the operation, accurately perform the operation, and carefully manage the patient postoperatively.
RESUMEN
This paper mainly studied the effect of ethanol extract of Selaginella doederleinii Hieron on the proliferation of two kinds of nasopharyngeal carcinoma cell lines, CNE-1 and C666-1, and their mechanisms of action. Extract was obtained by heat reflux extraction with ethanol, and the effect of extract on the extracellular matrix adhesion of the cells, on their proliferation process, as well as on their colony-forming ability were tested using MTT assay. The results showed that the yield of dry extract was 36.4%. 2.5 g/ml extract in the high concentration group exhibited inhibitory activity that was directly proportional to the concentration on CNE-1 cells, while not exhibiting obvious proportional trend in respect with C666-1 cells. However, the inhibition rates against two types of cells can both reach between 30% ~ 50%. Under the effect of ethanol extract of Selaginella doederleinii Hieron, proliferative capacities of C666-1 and CNE-1 cells were affected to some extent.
