Objective: To develop a HPLC method for the content and uniformity of dosage units of dehydroandrographolide in Xiaoyanlidan Tablets. Methods: ODS column was used and methanol water (70∶30) was used as a mobile phase. The detection wavelength was set at 250nm. Results: The linear range was from 2.14 to 34.24?g/mL (r =0.9999). The average recovery was 99.91%, and the relative standard deviation was 1.78%. Conclusion: The method is convenient and accurate.

Objective To establish a method for the quality control of Huox ia ng Zhengqi Capsules(HZC). Methods Radix Angelicae Dahuricae, Herba Pogostemo nis, Pericarpium Citri Reticulatae and Rhizoma Atractylodis Macrocephalae in HZ C were identified by TLC. The content of magnolol and honokiol were determined b y HPLC. The chromatographic conditions were: Diamonsil C18 (250 mm? 4.6 mm, 5 ? m) column, mobile phase being methanol- acetonitrile- water (20 ∶ 15 ∶ 9 ), and the detection wavelength at 294 nm.Results The qualitative identificat ion with TLC was specific. The linear ranges of magnolol and honokiol were 16.14 4～ 80.72 ? g/mL (r=0.9998) and 20.48～ 102.40 ? g/mL( r=0.9997) , the avera ge recovery were 97.07 % and 97.89 % and RSD were 1.17 % and 1.06 % resp ectively. Conclusion This method is sensitive, stable and accurate. It can be used for the quality control of HZC.

Objective To evaluate the application values of two kinds of single-platform flow cytometric methods,the Volumetric method based on flow sensor and the Trucount method based on Trucount beads,in the counts of T-lymphocyte subsets in peripheral blood of patients after transplantation.Methods The absolute number and percentage of CD4 +,CD8 +,and CD3 + T cells in peripheral blood samples from 107 patients after liver or renal transplantation were determined by the Trucount method and the Volumetric method,respectively,and their results were compared using paired t-test and linear regression analysis.Five samples with low CD3 + counts were selected and the precisions of the absolute number of CD4 +,CD8 + and CD3 + T ceils detected by the Volumetric method were evaluated.Results There was no significant difference in the levels of CD4+,CD4+/CD3+,CD8+,CD8+/CD3+,and CD4+/CD8 + in peripheral blood between the Trucount method and the Volumetric method (P ＞ 0.05),and the linear regression coefficients between them were from 0.9 to 1.1.When the concentration of CD3 + was equal or more than 40/μL,the coefficients of variation (CVs) were below 5.5％ for the Volumetric method.When the concentration of CD3 + was 20/μL,the CVs of CD3 +,CD4 +,and CD8 + were 5.19％,10.28％ and 6.48％,respectively.Conclusion The single-platform method based on flow sensor is accurate and reproducible for counting T-lymphocyte subsets in peripheral blood,which may be used to monitor the immune state of the patients after liver or renal transplantation.

Objective:To evaluate the prognostic efficacy of the Chinese Group on the Study of Severe Hepatitis B (COSSH) acute-on-chronic liver failure (ACLF) II score (COSSH ACLF IIs) and associated risk stratification in predicting short-term prognosis of patients with hepatitis B virus-related ACLF (HBV-ACLF).Methods:Clinical data of 224 patients with HBV-ACLF admitted to the First Affiliated Hospital of Wannan Medical College and the First Hospital of Quanzhou, Fujian Medical University from January 2018 to December 2021 were retrospectively analyzed. The patients were divided into survival group ( n=171) and fatal group ( n=53) according to 28-day survival status. The values of the COSSH ACLF IIs, the Chronic Liver Failure-Consortium (CLIF-C) ACLF score (CLIF-C ACLFs), the CLIF-C organ failure score (CLIF-C OFs), the Model of End-stage Liver Disease (MELD) score (MELDs), the MELD-sodium score (MELD-Nas), and the Child-Turcotte-Pugh score (CTPs) for 28-day mortality prediction were compared using the area under the receiver operating characteristic curve (AUC). The patients were divided into groups according to COSSH ACLF classification and COSSH ACLF IIs risk stratification, respectively. The differences in 28-day mortality between groups were compared by Kaplan-Meir method, and the consistency of the two ACLF classification systems was compared by Kappa consistency test. Results:The AUC, sensitivity, and specificity of the COSSH ACLF IIs in 28-day mortality prediction were 0.885, 0.981 and 0.731, respectively. For predicting 28-day mortality, the COSSH ACLF IIs achieved a higher AUC than the CLIF-C OFs, the MELDs, the MELD-Nas, and the CTPs ( P<0.01), while there was no significant difference in AUC between the COSSH ACLF IIs and the CLIF-C ACLFs ( Z=1.696, P=0.090). The cumulative 28-day mortality rates significantly increased with the ascending of COSSH ACLF grade and risk strata of the COSSH ACLF IIs (11.7%, 43.5% and 93.3%, P<0.001; 14.2%, 41.0% and 81.3%, P<0.001). The two ACLF grading systems showed a consistency in severity stratification of HBV-ACLF patients (Kappa=0.478, P<0.001). Conclusion:The COSSH ACLF IIs shows an excellent prognostic performance in predicting short-term mortality of HBV-ACLF patients. Using the new risk stratification scale can simplify the severity stratification of HBV-ACLF patients.
