Research progress of monoclonal antibodies in pharmacokinetic characteristics, analysis methods and method validation / 中国临床药理学与治疗学

In recent years, monoclonal antibodies (mAbs) have been developing rapidly and widely used in fields of tumor, immunity, blood and other systemic diseases. Global share of mAbs in prescription drug market had reached up to $ 140 billion, 15.3% by 2019. As macromolecule proteins, with special structures and physiological properties, mAbs have great differences in absorption, distribution, metabolism and excretion in vivo compared with small molecule drugs, including characteristics of relatively large molecular mass, high specificity and selectivity in target combination, non-linear pharmacokinetics, time dependence, long half-life and so on. Fully understanding of these special pharmacokinetic characteristics shall effectively guide analysis of mAbs. Meanwhile, the particularity and complexity of disposal mechanism in organisms greatly increase the difficulty of biological detection. As a result, it is necessary to establish exclusive, sensitive, accurate and repeatable quantification methods in biological samples. This article focuses on pharmacokinetic characteristics, main analytical methods, and methodology validation of quantification for mAbs in biological samples, expounding with comparisons of small molecular drugs, so as to prompt development of pharmacokinetic study of this kind of drugs.

@#Objective    To investigate the perioperative hemodynamic changes of off-pump coronary artery bypass grafting (OPCABG) patients monitored by pulse recorded analysis method (MostCare/PRAM devices) and its relationship with the prognosis. Methods    A total of 89 patients who underwent OPCABG from October 2016 to January 2017 in Beiijng Anzhen Hospital were included, including 53 males and 36 females aged 60.50±8.40 years. The hemodynamic changes were recorded. The patients were divided into two groups (a major adverse cardiovascular events group and a stable group) according to whether major adverse cardiovascular events occurred or not. The difference of hemodynamic changes between the two groups was analysed. Results    The mean percentage increases of stroke volume (SV) in the passive leg raising (PLR) test before opening chest and after chest closure were 23.00%±3.20% and 29.40%±3.70%, respectively. Hemodynamic data were analysed seven times, namely, anaesthesia, opening chest, heparin administration, coronary artery bypass grafting, protamine administration, thoracic closure and after operation. SV was significantly decreased during above periods, while systemic vascular resistance index (SVRI) was significantly increased. Cardiac circle efficiency (CCE) and maximum pressure gradient (dP/dT) were decreased after anaesthesia, and decreased to the lowest value during the procedure of bypass grafting, and then they began to increase gradually after the manipulation of bypass grafting was finished. Stroke volume variation (SVV) and pulse pressure variation (PPV) were slightly decreased during anaesthesia, then increased significantly through the whole surgery. Major adverse cardiovascular events occurred in 9 patients and 4 of them died. The basic mean values of SVRI, SVV and PPV of patients in the major adverse cardiovascular events group before opening chest were significantly higher than those of patients in the stable group. There was no significant difference in the mean values of CCE, dP/dT or SV between the two groups. There was no significant correlation between the prognosis and the mean values of SVRI, SVV, PPV, CCE, dP/dT or SV. Conclusion    The hemodynamic indexes are not stable, thus, it is necessary to monitor the perioperative hemodynamic changes of OPCABG patients timely by MostCare/PRAM device and adjust treatment measures accordingly.

Objective To study the preference relation between residence, sex, age and causes of accidental death of Chinese residents. Methods In this study, 72 residence-sex-age groups and 8 causes of accidental death were qualitatively and quantitatively analyzed by correspondence analysis using the official statistical yearbook issued from 2014 to 2018, and the preference values were calculated. Results Among the 576 pairs of correspondences between the residence-sex-age groups and causes of accidental death, 352 pairs （61.11%） showed a preference relation （preference value>0）. In terms of residence and sex, accidental death preference among Chinese residents was higher in rural areas than in urban areas, and males were higher than females. In terms of the causes of accidental death, the overall risk of accidental mechanical asphyxia and motor vehicle accidents was the highest among all age groups of Chinese residents. In terms of age, with the increase of age, the preference value of accidental death of Chinese residents showed a trend of first increasing and then decreasing. The comparative analysis results of the preference values of various causes of accidental death in different age groups showed that motor vehicle traffic accidents, accidental poisoning, death by crush and electric shock were more likely to occur in the working age group between 20 and 59 years old, accidental fall and fire were more likely to occur in the elderly group over 80 years old, and drowning and accidental mechanical asphyxia were more likely to occur in the minor group between 1 and 19 years old. Conclusion There are different preference relations between residence-sex-age groups and causes of accidental death in China. Therefore, effective control strategies and measures should be formulated for Chinese residents with preference for accidental death.

Optimization of Water Extraction Technology for Bupi Yangshen Granules Based on Multi-index Weighting Analysis Method Combined with Orthogonal Test / 中国药房

OBJECTIVE： To optimize the water extraction technology of Bupi yangshen granules， and to provide basis for the follow-up research and development of it. METHODS： The contents of astragaloside Ⅳ and salvianolic acid B in water extract of Bupi yangshen granules， were determined by HPLC-ELSD and HPLC-DAD. Using the comprehensive score of contents of astragaloside Ⅳ and salvianolic acid B and extract yield as index， weight coefficient of indicators were determined by AHP， CRITIC and AHP-CRITIC mixed weighting method. L9（34） orthogonal test was used to optimize decoction time， water volume and decoction times in water extraction technology of Bupi yangshen granules. Validation test was also performed. RESULTS： The weight coefficient determined by AHP-CRITIC mixed weighting method was the most reasonable. The optimal extraction technology was decocting twice， adding 12-fold water， 1 h each time. The results of 3 times of validation test showed that the average contents of astragaloside Ⅳ and salvianolic acid B were 8.79， 609.50 mg （total amount of 121 g medicinal herbs extracted from whole prescription）， respectively. The average extract yield was 31.24％. Average comprehensive score was 96.59（RSD＝1.01％，n＝3）. CONCLUSIONS： The optimized water extraction technology is reproducible， stable and feasible. It can provide a scientific basis for the follow-up development and industrial production of Bupi yangshen granules.

Content Determination of 5 Components in Curcuma wenyujin and Optimization of Processing Method in Production Place / 中国药房

OBJECTIVE： To establish the method for simultaneous determination of curdione， curcumenol， germacrone， furanodiene and β-elemene in Curcuma wenyujin， and to optimize its processing method in production place. METHODS： HPLC method was adopted. The determination was performed on ODS SP C18 column with mobile phase consisted of acetonitrile-0.05％ phosphoric acid solution （gradient elution） at the flow rate of 1.0 mL/min. The detection wavelength was set at 214 nm， and column temperature was 30 ℃. The sample size was 10 μL. 18 batches of sample medicinal materials were prepared by steaming-drying （10， 20， 30， 40 min）， or cooking-drying （drying temperature 50， 60， 70 ℃）， and then the contents of 5 components were determined. Relative relational degree （ri） obtained by grey relational analysis method as indexes was used to optimize the processing methods of C. wenyujin in production place using. RESULTS： The linear range of curdione， curcumenol， germacrone， furanodiene and β-elemene were 25.56-409.0， 2.05-32.8， 6.36-102.0， 9.14-146.0， 8.62-138.0 μg/mL （r≥0.999 2）， respectively. RSDs of precision， stability and reproducibility tests were all lower than 2.0％ （n＝6）. Quantitative limits were 0.34， 0.62， 0.11， 0.14 and 1.20 μg/mL， and detection limits were 0.10， 0.19， 0.03， 0.04 and 0.42 μg/mL， respectively. The average recoveries were 101.3％， 98.7％， 99.0％， 99.6％， 96.4％， respectively （RSD＜2.8％， n＝6）. The results of grey relational analysis showed that the relative relational degree （ri） from the processing technology of “boil for 10 min-drying at 50 ℃” was greatest， which had relatively small comprehensive effect on the contents of curdione， curcumenol， germacrone， furanodiene and β-elemene respectively. CONCLUSIONS： Established HPLC method can be used for content determination of 5 components in C. wenyujin. The results of optimization can provide reference for the selection of processing method of C. wenyujin in production place.
