ABSTRACT
Objective]To explore the diagnostic value of magnetic resonance imaging(MRI)combined transrectal ultrasound (TRUS)to guide prostate cancer detection at different serum prostate-specific antigen(PSA)levels.[Methods]Totally 278 patients who underwent a systematic biopsy were collected in our hospital from November 2014 to June 2016. Preoperative tests of PSA , MRI,TRUS were performed in all the included patients. According to the PSA level of 4~10 ng/mL,10~20 ng/mL,over 20 ng/mL, 278 cases were divided into three group of A ,B ,C. Retrospective analysis was performed within the three groups of diagnostic accuracy.[Results]In Group A,the areas under ROC for MRI+TRUS and TRUS were 0.73 and 0.59,respectively(P = 0.02). In Group B ,the areas under ROC for MRI+TRUS and TRUS were 0.68 and 0.56 ,respectively (P < 0.001). In Group C ,the area under ROC for MRI+TRUS and TRUS were 0.74 and 0.63,respectively(P < 0.001). There is more significant statistical difference in Group B and C.[Conclusion]MRI combined TRUS has higher diagnostic value in cancer detection than TRUS before biopsy between different PSA levels ,which Indicates that MRI combined TRUS is an effective method for the improvement of prostate cancer detection.
ABSTRACT
Objective By studying the prescriptions and medicines for treating rheumatoid arthritis (RA) prescribed by modem doctors, we tried to provide new ideas for developing the new medicines for treating rheumatoid arthritis. Methods 340 prescriptions on treating rheumatoid arthritis were collected from core medical periodicals and books published in the recent 20 years. Make a statistical analysis to the medicines in these prescriptions according to TCM etiological and pharmaceutical theories and modern researching foundlings. Results Among all 254 Chinese medicines used for treating RA, 32 medicines belong to worm and vine medicines, being used for 806 times. Conclusion The worm and vine medicines are frequently used in treating RA with good therapeutic effects combined with other kinds of medicines.
