Objective: To establish the UPLC-MS/MS method for the simultaneous determination of 10 active components (geniposidic acid, chlorogenic acid, shanzhiside methyl ester, 3,5-O-dicaffeoylquinic acid, geniposide, mussaenoside, β-ecdysone, andrographolide, wedelolacton, and dehydroandrographolide) in Yuye Qinghuo Tablets (YQT), in order to make a systemic, comprehensive, and scientific quality evaluation of the drug combined with the chemical pattern recognition method. Methods: The chromatographic separation was achieved on Agilent Zorbax SB C18 (50 mm × 3.0 mm, 1.8 μm); The mobile phase was consisted of methanol-0.1% acetic acid (containing 20 mmol/L ammonium acetate) at a flow rate of 0.3 mL/min with gradient elution, the mass spectrum was scanned by ESI+ and ESI- multiple reaction monitoring (MRM) mode. And the content analysis was carried out by cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares discriminant analysis (OPLS-DA) to comprehensively evaluate the difference in quality of YQT. Results: Under the optimized conditions, 10 components showed good linear relationships in the ranges of 0.352 5—14.100 0, 5.402—270.100, 0.205 8—8.232 0, 1.050—42.020, 4.020—160.800, 4.328—173.100, 2.044—204.400, 2.251—225.000, 0.232 8—9.312 0, and 4.708—188.300 μg/mL, respectively (r > 0.999 1), whose average recoveries were 95.02%—99.66% (RSD < 3.0%). The analysis results showed that the quality of the most batches was stable. However, it was found that there were still slight differences in the quality of different batches of drugs by CA and PCA. Finally, six symbolic components causing the quality differences among batches were screened out by OPLS-DA, they were andrographolide, dehydroandrographolide, mussaenoside, shanzhiside methyl ester, 3,5-O-dicaffeoylquinic acid, and chlorogenic acid, respectively. Conclusion: This simple, sensitive, and efficient method can be used for the rapid determination of main active components in YQT. The analysis of results combined with the chemical pattern recognition technology can comprehensively evaluate the drug quality as a whole, which provide new scientific basis and data processing methods for the quality control research of YQT.

In the magnetic induction tomography(MIT) system,the electrical conductivity of biological tissue is direct proportion to the phase difference between the excitation signal and the detection signal.To obtain the image of the contribution of tissue's electrical conductivity,the system must have the function of phase detection with high accuracy.The paper focuses on the means of digital phase detection,including FFT method,the correlation method and the classic method,which are ultimately compared with analogue phase detection method.The experimental results show that FFT method and the correlation method,with low error level and high linearity,can better detect the phase difference with the level of 0.1?.The digital phase difference detection provides a kind of effective method for MIT system.

ABSTRACT:Objective To a rare case of double primary cancer (hepatocellular carcinoma with gallbladder)to guide clinical application.Methods and Results We reported one case of primary hepatocellular carcinoma and gallbladder.A male patient,54 years old,had main complaints of intermittent right upper quadrant pain for 4 days. The abdominal CT of the local county hospital showed gallstones,gallbladder with liver infiltration.And then he went to the First Affiliated Hospital of Xi’an Jiaotong University for further treatment.Laboratory examination revealed:HBsAg(+),HBcAb(+),alpha-fetoprotein (AFP)> 60 500 ng/mL,carcinoembryonic antigen (CEA) 5.25 ng/mL.Abdominal CT showed hilar slightly stronger light echo groups:liver cancer or gallbladder cancer? Hepatic artery and portal vein CT imaging (CTA+CTV)examination showed the malignant tumor shadow in the inside of the left hepatic lobe huge,uneven thickening of the gallbladder wall,suspected liver disease with gallbladder infringement or gallbladder disease with liver infringement. With the preoperative preliminary consideration of primary liver cancer with infiltration of the gallbladder,we chose the operation as the resection of segment Ⅳ b and Ⅴ of the liver,cholecystectomy and T tube drainage.Pathological examination postoperative showed the bulky liver carcinoma grade Ⅲ and the poorly differentiated adenocarcinoma of gallbladder.A month later,abdominal CT showed the tumor spread intrahepatic,prompting the poor prognosis.Conclusion The two which are not continuous,which is the standard of double primary cancer,are not suitable for all double primary cancers.This case provides useful experience for future similar diagnosis and treatment of disease,and also helps us with timely and accurate identification of “metastatic”or “primary”,which is the key point for clinicians to give patients an effective treatment.
