ABSTRACT
Introduction: Liver diseases caused by hepatitis B virus (HBV) are pandemic infectious diseases that seriously endanger human health, conventional diagnosis methods can not meet the requirements in resource-limited areas. The point of acre detection methods can easily resolve those problems. Herein, we review the most recent advances in POC-based hepatitis B detection methods and present some recommendations for future development. It aims to provide ideas for future research.Areas covered: Epidemiological data on Hepatitis B, conventional diagnostic methods for hepatitis B detection, some latest point of care detection methods for hepatitis B detection and list out the recommendations for future development.Expert opinion: This manuscript summarized traditional biomarkers of different hepatitis B stages and recent-developed POCT platforms (including microfluidic platforms and lateral-flow strips) and discuss the challenges associated with their use. Some emerging biomarkers that can be used in hepatitis B diagnosis are also listed. This manuscript has certain guiding significance to the development of hepatitis B detection.

OBJECTIVE:To provide reference for improving the registration success rate of new drug research and develop-ment(R&D)enterprises after adjusting drug registration system in China. METHODS:The national drug policies,regulations and related documents were comprehensively studied and combed to explore the main contents of drug registration system adjustment and its effects on the R&D forms,drug patent and on-site verification. The suggestions were put forward. RESULTS & CONCLU-SIONS:The adjusted drug management system showed new definitions for new drugs and generic drugs in China,as well as de-tailed requirements and regulations for drug R&D conditions,process and on-site inspection. It enhanced the protection of patents and patentees. The new drugs should be assessed its market value and clinical advantages. Data contents and requirements for drug registration declaration were made the relevant adjustments. New drug R&D enterprises should develop drug listed license manage-ment system as early as possible based on the implementation of listed license management system pilot,improve its efficiency and benefit. The new drug R&D should notice the clinical efficacy and demand of market,focus on the drugs with good clinical effica-cy in common diseases,frequently-occurring diseases and major diseases;and those for treating rare diseases,the elderly and chil-dren disease can use easy access or fast track to accelerate the speed of drug registration. New drug R&D enterprises should im-prove the R&D conditions,and standardize the management of development process to ensure the effective and smooth develop-ment.
ABSTRACT
This study was aimed to optimize the alcohol precipitation techniques for honeysuckle extract in order to standardize the production of honeysuckle extract of Qingkailing Injection and reduce the differences among batches. The orthogonal test was applied in this study. The content of chlorogenic acid and galuteolin were taken as compre-hensive indicators. Multi-index comprehensive scoring method was used in the data analysis. Three influencing fac-tors, which were the fluid temperature, the stirring speed and the speed of adding alcohol, were optimized in the al-cohol precipitation techniques. The results showed that the optimal alcohol precipitation techniques were when the fluid temperature was 20℃, the stirring speed was 240 rpm and the speed of adding alcohol was one time of the ma-terial per minute. It was concluded that the optimized alcohol precipitation process was stable and feasible.
