1.Early diagnostic technology of breast cancer
Journal of International Oncology 2013;(6):453-455
The early diagnosis of breast cancer is crucial for improving the prognosis of patients.Some new diagnostic techniques can improve the early diagnosis rate.Studies show that microRNA,proteins in salivary,urinary polyamines could be used as novel tumor markers,with high sensitivities and specificities.With the help of optical technology and computers,the traditional diagnostic imaging technique also make a great breakthrough.Currently,image-guided minimally invasive biopsy techniques such as core needle biopsy and vacuum assisted biopsy have the advantages of accuracy,economy and little trauma,and can provide more samples,which have been widely applied in clinical practice.

Objective To compare the value of liquid-based preparations versus conventional smears in the diagnosis of non-thyroid neck masses from fine needle aspiration. Methods The two different methods were compared by the smear quality and the diagnostic accuracy for the aspiration samples of non-thyroid neck masses of 400 patients. Results The unsatisfactory rate for LBP was lower than that for CS (13.0% vs. 16.0%, P < 0.05). The sensitivity was 94.6% for LBP and 92.9% for CS, and the accuracy was 96.8% for LBP and 95.0% for CS. In the aspect of smear quality, LBP had advantages of quantity of cells, with clear background and easily identifiable cell morphology. Conclusions LBP has more advantages than CS in the identification of non-thyroid neck masses, especially for cervical nodal enlargement. But it has no marked advantages in the diagnosis of salivary gland lesions.

Objective To summarize seven-year experience in therapy for acute aortic syndrome.Methods Between May 2009 and June 2016,103 patients(75 males and 28 females)diagnosed as acute aortic syndrome underwent operation. The mean age was(43.13 ±15.07)years(20 -79 years).We applied hypothermic circulatory arrest and selective antegrade cerebral perfusion to achieve organic protection.92 patients underwent Sun's procedure.Bentall procedure was performed on 63 patients.9 patients accepted aortic valve repair or root plasty.Mitral valve was replaced in 5 patients.Right coronary artery bypass grafting was carried out on 3 patients.Results Mean cardiopulmonary bypass time was(231.7 ±55.9)min, and cross-clamp time was(138.1 ±31.3)min.Selective cerebral perfusion time was(31.0 ±6.8)min.9 patients died within postoperative 30-days.Conclusion Despite of progression of treatment on acute aortic syndrome, further researches are still required for severe complications and strategies of therapy.
