RESUMEN
Objective To explore the effect of transcutaneous electrical acupoint stimulation bracelet at Neiguan acupoint on the postoperative nausea and vomiting after thyroidectomy under general an-esthesia.Methods Seventy-two female patients underwent thyroidectomy,aged 18-50 years,ASA physical status Ⅰ or Ⅱ,were enrolled.The patients were assigned 1 ∶ 1 to two groups by permuted block randomization:the electrical stimulation group and the control group,36 patients in each group.Before an-esthesia induction,patients in both groups wore domestic transcutaneous electrical acupoint stimulation bracelets,and the electrodes were aimed at Neiguan acupoint.The electrical stimulation group started to stimulate Neiguan acupoint,and adjusted the proper intensity to make the patient feel tingling in the related area of the hand.When the bracelet was fixed firmly,turned it off.At the end of the operation,the bracelet was turned on with the stimulation intensity set before induction for 24 hours.Patients in the control group also wore the bracelet for 24 hours,but it was never turned on.The number of cases of postoperative nausea and vomiting(PONV)and the number of remedial cases of antiemetic drugs were recorded.Results Compared with the control group,the incidence of PONV and postoperative vomiting in the electrical stimula-tion group were significantly reduced within 24 hours after surgery(P＜0.05),and the differences were mainly in 1-6 hours after surgery(P＜0.05).There was no significant difference in the rate of remedial ca-ses of antiemetic drugs between the two groups at different time periods.Conclusion Transcutaneous electri-cal stimulation bracelet at Neiguan acupoint can effectively reduce the incidence of PONV within 24 hours after thyroidectomy.
RESUMEN
Objective To analyze the epidemiological characteristics of norovirus infectious diarrhea in the active monitoring of foodborne diseases in Jiangsu Province from 2015 to 2020, so as to provide reference for the prevention and control of foodborne diseases caused by norovirus. Methods Norovirus positive diarrhea cases were collected from sentinel hospitals in 13 districts and cities of Jiangsu Province, and their epidemiological and clinical characteristics were analyzed. Results Atotal of 3 620 norovirus positive cases were detected and isolated from 61 489 samples. The main serotype was GII (71.97%), the onset season was winter and spring, and the onset age was 1-3 years old and 14-34 years old. There was no significant difference in norovirus positive rate between different sexes, and the main symptom was diarrhea (incidence rate was 92.10%), Meat and meat products (20.20%) were the main types of suspected exposed foods. Conclusion Norovirus infection has obvious seasonal characteristics, and the population is generally susceptible. It is high in children and young people, and meat food was the main suspicious exposure food. We should continue to improve the ability of active monitoring, identification, early warning and control of foodborne diseases, so as to reduce the occurrence of foodborne diseases.
RESUMEN
Objective To analyze the correlation between intestinal flora changes and neonatal necrotizing enterocolitis (NEC)through 16S rRNA metagenomic sequencing and bacterial culture. Methods From September 2018 to March 2019, 10 NEC cases and 6 controls were randomly selected in the neonatal ICU ward of Nanjing maternal and child health care hospital to analyze the 16S rRNA metagenomic diversity of the for intestinal flora. The fecal samples and corresponding environmental samples were corrected from 51 cases of NEC children and their case controls to isolate and culture Clostridium. Results The dispersion of samples within the case group was smaller than that of the control group, and the sample diversity was higher than that of the control group. In the isolation and culture of Clostridium, the overall detection rate of Clostridium in the case group was 43.14% (22/51), and the detection rate of Clostridium butyricum was the highest (19.61%, 10/51). There was a statistical difference between the two groups (χ2=5.85, P=0.015 58). All Clostridium strains did not carry the A, B and E type neurotoxin genes. Conclusion: Increased intestinal flora diversity, intestinal flora abundance and changes in the abundance of Clostridium may be closely related to the intestinal environment of children with NEC; Clostridium, especially Clostridium butyricum, may be related to the occurrence of NEC.
