1.Overview of the British pharmaceutical standard-setting system
Chinese Journal of Health Policy 2014;(9):48-53
The paper presents a detailed review of British pharmaceutical standards including British Pharma-copoeia, European Pharmacopoeia, British Approved Names, Reference Standards and Non-Statutory Pharmaceutical Standards. British pharmaceutical standards are established by the British Pharmacopoeia Commission, Expert Advi-sory Groups, Panels of Experts and Working Parties, British Pharmacopoeia Commission Secretariat, British Pharma-copoeia Laboratory, and standard-setting procedures are clear and definite. British Pharmacopoeia standards are le-gally binding, and pharmaceutical products sold in the United Kingdom must comply with pharmacopoeia require-ments. British pharmaceutical standards can serve as an important reference for reforms to China’s pharmaceutical standards, including the scientific management of pharmaceutical standards, the improvement of organizational frame-works in the establishment pharmaceutical standards, the promptness of amendments to pharmacopoeia, and the uni-versality of international exchanges.

A simple,fast and highly sensitive fluorescence analysis method for detection of mercury ion was developed based on N-methyl-mesoporphyrin IX (NMM)/G-quadruplex DNA system and specific T-Hg-T mismatches.In this strategy,a large number of thymine was introduced into guanine-rich oigonucleotides which could form G-quadruplex.In the presence of Hg2+,guanine-rich oigonucleotides and complementary strand could form double-stranded DNA molecule by specific T-Hg-T mismatch pair,leading to destruction of G-quadruplex DNA structure.In the absence of Hg2+,guanine-rich oigonucleotides spontaneously formed G-quadruplex DNA structure that could bound NMM to generate intense fluorescence.Based on the above facts,a sensitive fluorescence biosensor for determination of Hg2+ was fabricated.And the optimal conditions for Hg2+ determination were as follows:buffer solution pH of 6.7,20 mmol/L KCl and 2.5 μmol/L NMM in buffer and incubation for 2 h.Under the optimal conditions,the fluorescence intensity signal change (F0-F) and the Hg2+ concentration exhibited a linear correlation within 50 nmol/L to 1000 nmol/L range with a low detection limit of 22.8 nmol/L (3σ).The biosensor exhibited good selectivity toward common metal ions.The developed method was successfully employed to detect Hg2+ in tap water with recovery of 106.1%-107.8%.
