Preliminary studies on critical control point of traceability system in wolfberry

As a traditional Chinese medicine, wolfberry (Lycium barbarum) has a long cultivation history and a good industrial development foundation. With the development of wolfberry production, the expansion of cultivation area and the increased attention of governments and consumers on food safety, the quality and safety requirement of wolfberry is higher demanded. The quality tracing and traceability system of production entire processes is the important technology tools to protect the wolfberry safety, and to maintain sustained and healthy development of the wolfberry industry. Thus, this article analyzed the wolfberry quality management from the actual situation, the safety hazard sources were discussed according to the HACCP (hazard analysis and critical control point) and GAP (good agricultural practice for Chinese crude drugs), and to provide a reference for the traceability system of wolfberry.

Establishment of traceability system of Chinese medicinal materials' quality

The quality of Chinese medicinal materials relates greatly to the clinical curative effect and security. In order to ensure the quality and safety of Chinese medicinal materials, a systematic and operable traceability system needs to be established. It can realize the whole process of quality and safety management of Chinese medicinal materials "from production to consumption" through recording and inquiring information and recalling defective products, which is an important direction for the future development of traditional Chinese medicine. But it is still at the exploration and trial stage. In this paper, a framework of Chinese medicinal materials' quality and safety traceability system was established on the basis of the domestic and international experience about the construction of food and agricultural products traceability systems. The relationship between traceability system of Chinese medicinal materials' quality and GAP, GMP, GSP was analyzed, and the possible problems and the corresponding solutions were discussed.

Properties of SiCp/6061-Al metal matrix composites prepared by infiltrating molten aluminum into ternary packing of SiC preforms

SiC particles reinforced aluminum matrix composites (SiCp/Al) with SiC content of more than 60%, without particle segregation for mirror substrate applications, are prepared by using the improved process. The improved process contains sintering process design, preform quality traceability, and equipment designing. The maximum SiC volume fraction of 70.4% is obtained by optimizing the selection of the following proportion: 71.4% coarse, 7.1% medium, and 21.5% fine particles. The variation of SiC volume fraction is correlated with the percentage of fine particles by using regression analysis. The preforms with the compressive strength above 10.34 MPa are prepared by sintering at 1600℃ for 2 h. Results showed that no defects in the scale of more than 10 µm are observed in the preforms. Due to the generation of a SiO2 layer during the sintering process, the formation of Al4C3 phase was inhibited. As the SiC particle volume fraction increased from 65.6% to 70.4%, the bending strength increased from 483.2 MPa to 585.2 MPa. The elastic modulus also increased from 174.2 GPa to 206.1 GPa, while the coefficient of thermal expansion between 50℃ and 350℃ decreased from 11.02 × 10−6/℃ to 9.53 × 10−6/℃.

Sustainable Utilization of TCM Resources.

Sustainable development aims to maintain utilization of finite resources without exhausting them and meet the demand of present and future generations [1]. Sustainability can only be achieved by balancing production and consumption in a reasonable dimension. It offers a vision of progress that integrates immediate and longer-term objectives. However, the nature of our current resource use endangers their future survival. Moreover, the consequences of our resource use in terms of impacts on the environment may induce serious damage to the environment. Sustainable utilization of natural resources should combine market demand of raw materials, ecological stability, and social benefits [2] and regard them as inseparable and interdependent components in the whole progress of industrial production. Traditional Chinese Medicine (TCM) has a long history of application and has attracted more and more world-wide attention for its significant effect in prevention and treatment of diseases. Wild medicinal resource is the basis of TCM and accounts for nearly 80% of all the sources of Chinese herbs. With the development of the modern TCM industry and gradual degradation of the natural environment, natural reserves of medicinal resources face a tremendous amount of pressure. Many medicinal plants are at risk of extinction and some adulterants have appeared on the market bringing to attention the need to ensure sustainable utilization of medicinal resources. More and more measures have been taken to guarantee the supply [3] and identification [4–6] as well as quality control [7, 8] and new drug development [9]. In this special issue, a total of 15 papers have been devoted to sustainable utilization of TCM resources. Identification of Radix Astragali using DNA barcoding, DNA barcode-based PCR-RFLP, and diagnostic PCR for authentication of Jinqian Baihua She (Bungarus Parvus), using ITS2 to identify Ferula species and indirubin-containing medicinal plants, are included. Rapid identification of plants in the Asteraceae with improved RBF-ANN classification models based on MOS-sensor E-nose is also provided. Introduction and cultivation can supply raw medicinal materials in short supply and play an important role in the sustainable utilization of TCM. Prevention and cure of diseases and insect pests and characteristics of soil microbial community in ginseng cultivation are offered. A systematic review on the production mode of Chinese herbal medicines is also presented. This special issue also reports natural resource monitoring of Rheum tanguticum by multilevel remote sensing. Traceability based on chemical two-dimensional barcode for controlling quality in the whole process of the industrial chain of TCM is included. Finally, measuring Agarwood formation ratio quantitatively by fluorescence spectral imaging technique and determining oleanolic and ursolic acids using hyphenated ultrasound-assisted supercritical carbon dioxide extraction and chromatography are introduced. Readers of this special issue will find not only different identification methods and updated reviews on cultivation, but also some important issues influencing quality control. The industrial chain of TCM, from the production of raw materials to the sale of the finished products, is a complicated multilink process. There are still some key questions to be resolved in the whole process including but not limited to breeding, prevention and cure of diseases and insect pests, quality traceability, exploiting new medicinal resources, and the mechanism of drug metabolism.

Implication pharmaceutique dans le cadre d’essais cliniques institutionnels : évaluation de la qualité des opérations de mise sous forme pharmaceutique

For academic clinical trials, the hospital pharmacy may be required to perform the specific activity of preparing investigational drugs. With regards to such activity, and in light of the recent changes in the regulatory environment, the main objective of this study was to evaluate whether quality levels and traceability were in compliance with the applicable regulatory standards. In order to do so, two internal audits have been conducted, the first on the compliance of operations with existing regulatory standards and the second on the quality of traceability of the operations. The proportion of academic clinical trials is constantly growing and currently represents 41% of the total clinical trials in the establishment. An average of 29,000 therapeutic units of investigational drugs are prepared each year (84% under the form of capsules). An overall conformity level of 75% and 88% has been identified in the aforementioned audits, respectively. Such audits have also allowed for the identification of weaknesses in current practices as well as potential improvement areas to achieve better compliance. The hospital pharmacy can provide expertise for the preparation of specific dosage or drugs that are not available on the market. It also can be involved for the conception of appropriated packaging function of the study design. Results of audits encourage us to continue this activity with a satisfactory level of quality in accordance with the necessary requirements to ensure the safety of patients and the quality of clinical trials conducted.
