Objective To evaluate the possible causes of misdiagnosis of minimal breast carcinoma (MBC). Meth-ods The possible causes of misdiagnosis of 90 cases of MBC confirmed by pathology were retrospective analyzed. Accord-ing to the maximum diameter of the lesion, 90 cases were divided into 0.5-1.0 cm group (n=55) and≤0.5 cm group (n=35). And these two groups were subdivided into correct and misdiagnosed groups. The two-dimensional ultrasound findings were observed by using SIEMENZ S2000, GE vivid7 and GE vivid9 color Doppler ultrasound instruments, and reasons of misdiag-nosis were analyzed. Results There were 32 cases were misdiagnosed in 90 patients with MBC. There was significant differ-ence in boundary of misdiagnosis between diameter 0.5-1.0 cm group and≤0.5 cm group. There were significant differences in boundary and calcification between misdiagnosed group and correct group in diameter 0.5-1.0 cm group (P<0.05). There were also significant differences in A/T ratio and accompanying by multiple benign nodules between misdiagnosed group and correct group in diameter≤0.5 cm group (P<0.05). Conclusion The misdiagnosis in MBC is because of different lesion sizes. The misdiagnosis happens in the maximum diameter of the lesions between 0.5-1.0 cm that showed manifestation of sharp edges, no micro-calcification in sonographic features of benign. The misdiagnosis happens in maximum diameter of le-sions≤0.5 cm that manifested as the aspect A/T ratio<1 and characterized by multiple nodules.

A liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the determination of bistrifluron, cyantraniliprole and SYP9080 residues in fruits and vegetables. The analytes were extracted from samples with acetonitrile, and purified by dispersion solid phase extraction using C18 and primary secondary amine (PSA) as solid phase adsorbent, then analyzed by LC-MS/MS. Bistrifluron and SYP9080 were analyzed with negative ion multiple-reaction monitoring (MRM), cyantraniliprole was analyzed with positive ion MRM. The matrix-induced weakening effect was observed in the analysis of cyantraniliprole and SYP9080 in several samples including cucumber, apple and onion, and the weakening extent of the matrix-induced effect depended on the sample properties. But no matrix effect was found in the analysis of bistrifluron in several samples. The interference of matrix was reduced by using the matrix-matched calibration standards curve in the analysis of cyantraniliprole and SYP9080. Bistrifluron could be quantified by an external standard of the matrix-matched calibration standards or the pure solvent calibration standards. The linear range was from 0.2 μg/L to 100 μg/L for bistrifluron, cyantraniliprole and SYP9080 with the good correlation coefficients (r≥0.9990). The recoveries of cucumber, grape, apple and scallion added bistrifluron at 0.005-2 mg/kg were 79.8%-99.9%, with relative standard deviations (RSD) of 3.6%-9.8%. The limits of quantification (S/N=10) were 0.210 μg/kg, 0.160 μg/kg and 0.004 μg/kg, and limits of detection (S/N=3) were 0.064 μg/kg, 0.048 μg/kg and 0.001 μg/kg for bistrifluron, cyantraniliprole and SYP9080, respectively.
