Identification of chemical constituents of Xiaochengqi Decoction by UPLC-Q-TOF/Fast DDA combined with UNIFI software / 中国中药杂志

Based on the combination of ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF) and Waters UNIFI software, the chemical constituents of the classic prescription Xiaochengqi Decoction were qualitatively analyzed and identified. The UPLC conditions are as follows: Acquity HSS T3 reverse phase column(2.1 mm ×100 mm, 1.8 μm), column temperature of 30 ℃, mobile phase of 0.1% formic acid aqueous solution(A)-acetonitrile(B), and flow rate of 0.3 mL·min~(-1). High-resolution MS data of Xiaochengqi Decoction were collected in ESI~(+/-) modes by Fast DDA. The structures of the chemical constituents were tentatively characterized or identified by UNIFI software according to the retention time of reference standards and characteristic fragment ions in MS profile, and literature data. A total of 233 components in Xiaochengqi Decoction were identified, with 93 from wine-processed Rhei Radix et Rhizoma, 104 from bran-processed Aurantii Fructus Immaturus, and 36 from ginger-processed Magnoliae Officinalis Cortex. These 233 components included anthraquinones, flavonoids, lignans, alkaloids, coumarins, and phenylethanoid glycosides. The result provided experimental evidence for the further study on establishment of quality standard and product development of the formula.

Analysis of chemical constituents in classical prescription Danggui Buxue Decoction based on RP-Q-TOF-MS and HILIC-Q-TOF-MS / 中国中药杂志

The chemical constituents of classical prescription Danggui Buxue Decoction were analyzed by reversed-phase(RP) chromatography and hydrophilic interaction chromatography(HILIC) coupled with quadrupole time-of-flight mass spectrometry. RP separation of Danggui Buxue Decoction was performed on ACQUITY UPLC HSS T3(2.1 mm×100 mm, 1.8 μm), while HILIC separation was on Waters BEH Amide(2.1 mm×100 mm, 1.7 μm). Mass spectrometry(MS) data were acquired in both negative and positive ion modes. Chemical constituents of Astragali Radix and Angelicae Sinensis Radix were searched from Reaxys and thus the in-house library was established. MS data were further analyzed by MassLynx 4.1 combined with in-house library, HMDB, Reaxys, and comparison with reference substances. In conclusion, a total of 154 compounds were identified and characterized: 16 saponins, 44 flavonoids, 10 phthalides, 7 phenylpropanoids, 15 bases and the corresponding nucleosides, 30 oligosaccharides, and 32 other compounds. Among them, 65 compounds were detected by HILIC-MS/MS. This study provides experimental evidences for the material basis research, quality control, and preparation development of Danggui Buxue Decoction and a reference method for comprehensive characterization of Chinese medicine decoctions typified by classical prescriptions.

Primary hepatic diffuse large B cell lymphoma: a case report

In this report we describe a rare case of primary hepatic diffuse large B cell lymphoma in a 67-year-old man who presented with abdominal pain, deteriorated liver function, elevated lactate dehydrogenase. He was found to have diffuse nodular intrahepatic space-occupying lesion with normal alpha-fetoprotein and carcino-embryogenic antigen. The final diagnosis was made by percutaneous biopsy of the liver as the clinical manifestation not consistent with common liver diseases. The patient was treated with R-CHOP [rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone] without surgical resection with a favorable response. However, serious and complication was occurred after 4 cycles of chemotherapy, and the patient finally died of concurrent acute respiratory distress syndrome

Accuracy of FibroScan for the diagnosis of liver fibrosis influenced by serum alanine aminotransferase levels in patients with chronic hepatitis B / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To analyze whether or not the accuracy of liver stiffness measurement (LSM) with transient elastography (FibroScan) for the diagnosis of liver fibrosis influenced by serum alanine aminotransferase (ALT) levels in patients with chronic hepatitis B.</p><p><b>METHODS</b>213 consecutive CHB patients who underwent liver biopsy and LSM were enrolled and divided into three groups by the criteria of ALT < 1 x ULN, 1 x ULN ≤ ALT < 2 x ULN and ALT ≥ 2 x ULN. The areas under the receiver operating curve(AUC) were analyzed and the accuracy of FibroScan for the diagnosis of liver fibrosis were detected in the three groups.</p><p><b>RESULTS</b>Significant correlation existed between the stages of liver fibrosis and LSM (rs = 0.773, 0.889 and 0.412, P < 0.05). AUCs of LSM in all patients for significant fibrosis (F ≥ 2, F0-1 vs F2-4) and cirrhosis (F = 4, F0-3 vs F4) were 0.916 and 0.971 respectively. The accuracy of diagnosis for significant fibrosis and cirrhosis were 84.0% and 93.4% respectively. AUCs of LSM in ALT < 1 x ULN, 1 x ULN ≤ ALT < 2 x ULN and ALT ≥ 2 x ULN groups for significant fibrosis were 0.939, 0.967 and 0.687 respectively. The sensitivity of the three groups was 90.0%, 89.7% and 47.8% respectively. The accuracies of the three groups was 90.5%, 93.9% and 68.4% respectively. The AUC, sensitivity and accuracy of ALT ≥ 2 x ULN group for significant fibrosis were significantly lower than the other two groups. AUCs of LSM in three groups for cirrhosis were 0.970, 0.985 and 0.952 respectively. The sensitivities of the three groups were 93.8%, 100% and 100% respectively. The accuracies of the three groups were 88.9%, 95.9% and 92.1% respectively. The AUCs, sensitivity and accuracy for cirrhosis of the three groups didn't change with elevated ALT.</p><p><b>CONCLUSIONS</b>Transient elastography (FibroScan) is a reasonable noninvasive tool to diagnose significant fibrosis, especially liver cirrhosis in CHB patients. The accuracy of FibroScan for diagnosis of liver cirrhosis may not be influenced by elevated ALT. While in ALT ≥ 2 x ULN group, the accuracy of FibroScan for diagnosis of significant fibrosis was significantly lower as compared to the ALT ≤ 2 x ULN groups.</p>
