OBJECTIVETo elucidate the necessary and research of accelerating basic research of Chinese standard pieces as standard materials.

METHODAccording to over 10 years accumulated experience and be keenly aware of the author, the evaluation method of standardized processing technology and Chinese pieces quality, aimed at consummated the standard material of the quality evaluation of Chinese herbal pieces at the current situation, and inaccordance with the need of improving quality standard system of Chinese herbal pieces, illustrate the necessity of accelerating basic research of Chinese standard pieces as standard materials; from the technical specification for collecting and processing of raw materials, and the technical specification, homogenized sample, packaging, storage and etc., for processing of candidate standard pieces, determine the methods and steps of technical specifications for standard pieces as the standard substance, determine the methods and steps of technical specifications for standard pieces as the standard substance.

RESULT AND CONCLUSIONTo speed up the basic research of standard of Chinese medicine pieces as of standard material is very necessary. The research objective is to specificate the processing technical for a number of standard pieces, to identify technical specifications and to ascertain the guiding principle and technical specification of decoction pieces as standard substance. This research will provide basic scientific data relevant national departments to apply for the accreditation of the standard substance.

This article elaborated the importance of strengthening the Chinese herbal pieces industry management from aspects such as the strengthening of process management, production and marketing integration of herbal pieces, self-discipline of Chinese herbal pieces industry, high price for high quality, scientific research management and construction of laws and regulations. It explored key issues of Chinese herbal pieces from aspects such as industry management, stabilization of herbal pieces quality and clinical efficacy guarantee. It suggested that the industry management of Chinese herbal pieces should be strengthened with stable quality to ensure the clinical efficacy.

OBJECTIVE: To evaluate and compare whole exome sequencing (WES) and targeted panel sequencing in the clinical molecular diagnosis of the Chinese families affected with inherited retinal dystrophies (IRDs). METHODS: The clinical information of 182 probands affected with IRDs was collected, including their family history and the ophthalmic examination results. Blood samples of all probands and their relatives were collected and genomic DNA was extracted by standard protocols. The first 91 cases were subjected to the WES and the other 91 cases were subjected to a specific hereditary eye disease enrichment panel (HEDEP) designed by us. All likely pathogenic and pathogenic variants in the candidate genes were determined by Sanger sequencing and co-segregation analyses were performed in available family members. Copy number variations (CNVs) detected by HEDEP were further validated by multiplex ligation-dependent probe amplification (MLPA). As PRGR ORF15 was difficult to capture by next generation sequencing (NGS), all the samples were subjected to Sanger sequencing for this region. All sequence changes identified by NGS were classified according to the American College of Medical Gene-tics and Genomics and the Association for Molecular Pathology (ACMG/AMP) variant interpretation guidelines. In this study, only variants identified as pathogenic or likely pathogenic were included, while those variants of uncertain significance, likely benign or benign were not included. RESULTS: In 91 cases with WES, pathogenic or likely pathogenic variants were determined in 30 cases, obtaining a detection rate of 33.00% (30/91); While in 91 cases with HEDEP sequencing, pathogenic or likely pathogenic variants were determined in 51 cases, achieving the diagnostic rate of 56.04% (51/91), and totally, the diagnostic rate was 44.51%. HEDEP had better sequencing coverage and read depth than WES, therefore HEDEP had higher detection rate. In addition, HEDEP could detect CNVs. In this study, we detected disease-causing variants in 29 distinct IRD-associated genes, USH2A, ABCA4 and RPGR were the three most common disease-causing genes, and the frequency of these genes in Chinese IRDs population was 11.54% (21/182), 6.59% (12/182) and 3.85% (7/182), respectively. We found 43 novel variants and 6 cases carried variants in RPGR ORF15. CONCLUSION NGS in conjunction with Sanger sequencing offers a reliable and effective approach for the genetic diagnosis of IRDs, and after evaluating the pros and cons of the two sequencing methods, we conclude that HEDEP should be used as a first-tier test for IRDs patients, WES can be used as a supplementary molecular diagnostic method due to its merit of detecting novel IRD-associated genes if HEDEP or other methods could not detect disease-causing va-riants in reported genes. In addition, our results enriched the mutational spectra of IRDs genes, and our methods paves the way of genetic counselling, family planning and up-coming gene-based therapies for these families.

Objective To observe the effect of acupuncture on cerebral glial fibrillary acidic protein(GFAP)expression of brain injury caused by intrauterine infection in neonatal rats.Methods Forty-three Wistar pregnant rats were divided into 2 groups:lipopolysaccharide(LPS)(n=35)and normal saline(n=8).Pregnant rats were consecutively injected intraperitoneally with LPS(450 ?g/kg)or saline on gestation 17 d and 18 d.LPS group were randomly divided into acupuncture group and model group.Acupuncture group were given acupunctured from 7 d to 21 d.GFAP expression was assayed with immunohistochemical technique.Results The number of GFAP immunoreaction(IR)strongly-positive neurons in the cerebral white matter was more in acupuncture group,less in model group and only very weakly IR-positive neurons were found in normal saline group.Conclusion Acupuncture can up-regulate the expression of GFAP in the cerebral white matter,which may contribute to the effect of acupuncture in improving brain injury caused by intrauterine infection.

Chinese meteria medica (CMM) chain is a long-span chain covering agriculture which mainly depends on the forces of nature as well as high-tech CMM industry, CMM expertise industry and fast developing CMM circulation industry. Imbalance among the development of these industries produces bottlenecks and hinders the operation of the entire production chain. After analyzing the structure of Chinese meteria medica industrial chain from the perspective of national economy industry, three industry classifications and differentiation of factor intensity, we conclude that the complex structure of CMM industry chain is attributable to these three aspects. And the complexity is mainly shown at complex industry, varied product types, different coordination of various industrial sections and different technical growth speed of varied industry. We propose that structural complexity is the natural property of the chain, which is the main reason of industry sector development imbalance and bottleneck. Results of this research could provide theoretical analysis for future research on the coordination of industrial chain and the efficiency of resource allocation.
