Objective:To investigate the application effect of propofol combined with remifentanil for anesthesia in children undergoing plasma adenoidectomy.Methods:Clinical data of 103 children who underwent plasma adenoidectomy in our hospital from Apr 2023 to Apr 2024 were retrospectively analyzed.Children were divided into two groups according to different anesthesia schemes.Children who received propofol+ketamine anesthesia were enrolled in the control group(n=52)and children who received propofol+remifentanil anesthesia were enrolled in the study group(n=51).Hemodynamic parameters were compared between the two groups at four time points:before anesthesia(T0),immediately after extubation(T1),5 minutes after extubation(T2),and 10 minutes after extubation(T3).The pain scores(CHIPPS)of the two groups were compared at 10,20,and 30 min after extubation.Post-anesthesia evaluation of discomfort(PAED)and incidence of restlessness during recovery in children were compared.The indicators of stress response(cortisol and epinephrine)were measured preoperatively and 1 day postoperatively.Total perioperative adverse events were analyzed.Results:The recovery times for spontaneous breathing,eye-opening,and extubation in the study group were shorter than those in the control group(P＜0.05).The heart rate and mean arterial pressure level in the study group at T1-T3 were lower than those in the control group(P＜0.05).The CHIPPS scores at 10,20,and 30 min after extubation and PAED scores during the recovery period in the study group were lower than those in the control group(P＜0.05).The incidence of restlessness during the recovery period in the study group was lower than that in the control group(P＜0.05).The levels of cortisol and epinephrine in the study group were lower than those in the control group on day 1 after surgery(P＜0.05).There was no significant difference in the overall incidence of adverse reactions between the two groups(P＞0.05).Conclusion:The use of propofol combined with remifentanil in plasma adenoidectomy can effectively shorten the recovery time of anesthesia in children,enhance analgesic effects,reduce blood circulation fluctuations and stress reactions,and reduce the incidence of restlessness,with reliable safety.

Respiratory syncytial virus(RSV)is a major cause of severe lower respiratory disease and can infect all populations,posing a significant health threat to infants and the elderly.After more than 60 years of research,there are only 2 RSV vaccines and 2 preventive monoclonal antibodies be licensed,but the use of the population is severely limited,expensive and difficult to large-scale popularization.RSV vaccine development faces a number of obstacles,such as the lack of animal models,avoidance of RSV immunity,and short duration of immunity.Since the failure of formalin inactivated RSV vaccine trials,RSV vaccine development has become more cautious and difficult.This article briefly reviews the research status of RSV vaccines,and introduces several representative vaccines currently under development,in order to facilitate researchers to review the latest progress and contribute to promoting vaccine research.

Objective To study the multicomponent in vivo dynamic process in Chuanxiong Rhizoma;To elaborate in vivo metabolic profiling. Methods HPLC was used to establish the fingerprint of aqueous extract of Chuanxiong Rhizoma, and multicomponent changes were detected at the same time. Closed-loop intestine method was used to study the multicomponent changes of oral administration of Chuanxiong Rhizoma after stomach-intestine-liver process. Results Totally 17 components were detected in the fingerprint of aqueous extract of Chuanxiong Rhizoma and they were basically stable in the digestive juice. For in vivo metabolism, 4 components were metabolized by intestinal flora;3 components were metabolized by liver;2 new components were the metabolites of intestinal flora;1 component was the metabolite of liver. Conclusion Multicomponent sequential metabolism and closed-loop intestine method were used to clarify that multicomponent metabolic profiling was feasible, and it could provide experimental basis for the metabolism of traditional Chinese medicine.

OBJECTIVE: To explore an useful and practical method for three-dimensional reconstruction of cochlear microstructure. METHOD: A digital image dataset of magnified forty times of human cochlear tissue can be get from the serial sections of transverse cedukol images of male cadavers temporal bone. Photoshop 6.0 and Amira 3.0 software were used to deal with the digital image dataset, such as image-connecting and image inner-location and three-dimensional reconstruction of cochlear and scala media. RESULT: The result of three-dimensional reconstruction of the cedukol images represents the anatomy of human cochlear and scala media transparently and objectively. CONCLUSION The three-dimensional reconstruction technique used in the study is practical for three-dimensional of inner ear microstructure.

Objective To develop a rapid kit applied to the field for detection of antibody to schistosome in human sera. Methods A new kit for rapid detection of antibody to schistosome was developed through improving the dot immunogold filtration assay (DIGFA). A total of 100 cases of sera from chronic schistosomiasis patients and 140 from healthy people, HBV patients and the people infected with other parasites were detected by the kit. The sensitivity, specificity, Youden's index and Kappa value were utilized as the evaluation standard. Results The sensitivity of detecting antibody to schistosome, specificity, Youden's index and Kappa value were 92% , 95.08% , 0.87 and 0.87, respectively. The cross reaction to patients with clonorchiasis was 5%. Conclusion DICFA kit is practical for antibody to schistosome detection in the field because of its advantages such as smaller serum needed and faster in reaction.
