ABSTRACT
Objective To investigate the effect of pathophysiology case-based learning(CBL)method on scores of pediatrics.Methods Undergraduates from 2005 grade at Chengde medical college were divided into two groups:experimental group(n=138,CBL method)and control group(n=136,conventional teaching method).The scores of pediatrics between the two groups were compared.The pediatrics test paper was divided into two types:type B,which was tightly connected with the pathophysiology knowledge and type F,which had less connection with pathophysiology knowledge.The accuracy rates of both groups were compared.Correlation analysis on scores between pathophysiology and internal medicine,surgery,pediatrics,obstetircs and gynaecology was made.Results No significant difference in total scores of pediatrics was observed between the two groups(P＞0.05);total accuracy rate of experimental group was higher than that of control group(P＞0.05);similar total accuracy rates of type F test paper were observed in both groups(P＞0.05);positive correlations in scores between pathophysiology and internal medicine,surgery,pediatrics,obstetircs and gynaecology were found.Conclusions Satisfactory long-term effect are received by applying pathophysiological CBL model since it can promote the application of pathophysiological knowledge in pediatrics,however,no apparent effect on students'clinical ability can be obtained from the mere application of CBL in pathophysiology course.
ABSTRACT
Objective To analyze the key factors on long-term effect for comprehensive interventional therapy of primary liver cancer.Methods The clinical data,therapeutic protocols and follow-up of 56 patients with primary liver cancer survived for more than 5 years after comprehensive interventional therapy were analyzed retrospectively.Results Before TACE,20 patients were in clinical stageⅠ,35 were in stageⅡand one was in stageⅢ,including hepatic function of grade A(36 cases),grade B(20 cases),and grade C (0 case).The tumor patterns were consisted of mononodular type(32 cases),multinodular type(24 cases),and diffuse type(0 cases).The diameter of tumor demonstrated less than 3 cm(10 cases),3-5 cm(20 cases), 5-10 cm(19 cases)and more than 10 cm(7 cases).Thirty-three cases(58.9%)were treated by only TACE for the original lesions,while 23 cases(41.1%)were treated by TACE combined other treatment including TACE combined PEt(11 cases),TACE combined RFA(4 eases),TACE combined radiotherapy(one case),and TACE combinedⅡ-staged resection(7 cases).During follow-up,24 patients with hepatic recurrence and 17 cases of distal metastasis were treated by TACE and other anti-tumor treatment.Complications after interventional therapy in 20 cases were also treated.All cases survived for more than 5 years after interventional therapy including 3 more than 10 years.Conclusions Tumor factors,liver function, standardized TACE,combination of TACE with other anti-tumor therapy,treatment of hepatic recurrence and distal metastasis and complications are the key points to improve the long-term survival rate for primary liver cancer treated by comprehensive interventional therapy.
