Objective To explore the effectiveness of integrating virtual simulation technology with case-based learning(CBL)in the teaching of clinical blood transfusion testing technology.Methods From January to June 2024,99 undergraduate students majoring in medical laboratory science at our university were selected and divided into an observation group(50 students)and a control group(49 students)based on their classes.The control group followed a traditional theoretical teaching model,while the observation group employed virtual simulation technology combined with CBL.Results The study compared as-sessment scores for theory learning,practical skills,case analysis,and comprehensive quality,teaching effects such as coordina-tion and cooperation abilities,self-efficacy measured by the GSES scale,and teaching satisfaction between the two groups.The results indicated that the observation group had significantly higher scores in all assessment categories,teaching effect abilities,and total GSES scores compared to the control group(P＜0.05).The total teaching satisfaction rate in the observation group reached 100%,significantly higher than the 80% in the control group(P＜0.05).Conclusion The integration of virtual simu-lation technology with CBL innovates the teaching model for clinical blood transfusion testing courses,effectively enhancing students'professional skills and comprehensive quality,boosting self-efficacy,and achieving high student satisfaction,demon-strating significant potential for broader application.

Objective To observe the clinical efficacy of ganciclovir in treatment of children with viral encephalitis.Methods 80 children with viral encephalitis were randomly divided into observation group and control group.All patients received the comprehensive treatment including anti-spasm,dehydration,control of body temperature,decreased intracranial pressure and drugs of improving brain metabolism.40 children in the observation group received intravenous ganciclovir.40 patients in the control group received intravenous ribavirin.The clinical effect of the two groups was compared.Results The total effective rate of observation group was 92.5％,that of the control group was 70.0％,the difference was statistically significant (x2 =6.721,P ＜ 0.05).In the observation group,the main clinical symptoms including fever,headache,vomiting,convulsions and the disappearance time of unconsciousness were significantly shorter than the control group(t =5.270,9.730,5.749,5.903,5.421,all P ＜ 0.05).The incidence rate of adverse reactions in the observation group was 7.5％,which was lower than 17.5％ in the control group,but the difference was not statistically significant (all P ＞ 0.05).Conclusion Ganciclovir in the treatment of children with viral encephalitis can improve clinical symptoms in a short time,and adverse reactions are mild,which can be used as the ideal choice for treatment of children with viral encephalitis.
