Speeding up the training of quality personnel in clinical medicine is an important historic mission of clinicians. Practice has proven that the training, growth and maturity of quality clinical personnel are inseparable from clinical practice. Thus, firstly, clinical workers must, in accordance with the goals of training, rigorously enforce process management, including implementation of the training regulations, strict assessments, and cultivation of abilities in doing scientific research and writing up research papers. Secondly, the overall quality of postgraduates must be enhanced. Thirdly, files of postgraduates must be set up. Fourthly, experience in training academic degree postgraduates in clinical medicine should be constantly summed up, including ways of strengthening organization and control and clarifying goals and requirements

Objective To investigate the diagnostic value of PIgP/SC in diagnosis of primary hepatic cancer.Methods 58 patients with primary hepatic cancer,60 patients with liver cirrhosis and 60 healthy volunteers were studied.4 ml fasting venous blood was collected from all subjects.Serum level of AFP was detected with electrochemical chemiluminescence immunoassay system and plasma PIgR/SC level was detected by ELISA method.The level of PIgR/SC and AFP was detected at one week after surgical resection in patients with hepatic cancer.Results The levels of AFP and PIgR/SC in the three groups were significantly different (P＜0.01),and PIgR/SC was higher than that in patients with cirrhosis and volunteers (P＜0.01).There was no significant difference between patients with liver cirrhosis and liver cirrhosis(P＞0.05).AFP was higher in patients with HCC than patients with cirrhosis and volunteers.AFP was higher in patients with cirrhosis than volunteers,and the difference was statistically significant(P＜0.01).Sensitivity of PIgR/SC and AFP was 89.3％ and 54.8％,specificity was 84.6％ and 91％,Youden index was 0.751 and 0.458,AUC was 0.920 and 0.761,respectively.There was significant difference in AUC (Z=3.251,P＜0.05) of the two detection indexes for detection of primary hepatic cancer.Conclusion The value of PIgR/SC in diagnosis of primary liver cancer may by higher than that of AFP.
