ABSTRACT
As one of the pathogenic mechanisms contained in The Inner Canon of Yellow Emperor （《黄帝内经》）， “disease with latent pathogen induced by a new pathogen” means that the induced new pathogen resulted to a combination of the latent previous pathogen and the new pathogen， which caused the disease. Based on this， it is believed that the change of “nodule-cancer transformation” of pulmonary nodules is actually based on the deficiency of original qi， and the new pathogen induces the latent pathogens like phlegm coagulation， qi stagnation， blood stasis， toxicity， so healthy qi can not drive the pathogens out， and the long-time detention generated into cancerous turbidity， and deve-loped into cancerous tumour at the end. Therefore， based on the three-stage treatment of unformed cancer， dense cancerous toxin， and developed cancer， the clinical practice applied six methods of clearing， expelling， dissipating， tonifying， harmonizing， and transforming， taking into account both the manifestation and root cause， moving the treatment window of pulmonary nodules forward， attacking the pathogens when the toxin was not yet overbearing， supporting the healthy qi before declining， delaying the process of nodules-cancer transformation， and providing ideas for the prevention and treatment of pulmonary nodules “nodule-cancer transformation” in traditional Chinese medicine.
ABSTRACT
This article has systematically reviewed the name， origin， scientific name， producing area， quality evaluation， harvesting and processing methods of Polygonati Odorati Rhizoma（POR） by consulting the materia medica， medical books， prescription books and modern literature， in order to provide a reference for the development of famous classical formulas containing POR. Yuzhu was first recorded in the Shennong Bencaojing under the name of Nyuwei. After that， Weirui was used as the rectification name in the subsequent dynasties， and in recent times， the name of Yuzhu is mostly used in materia medica and prescription books. In ancient times， there were different names for Yuzhu， such as Nyuwei， Weiwei and Weirui. The names of the three are similar and there was a mixed use of the same name and foreign matter in history. In the Tang dynasty， SU Jing listed Nyuwei with the effect of curing dysentery in the intermediate of herbal part of Xinxiu Bencao according to its different efficacy. However， based on Shennong Bencaojing， Mingyi Bielu and the different energy efficiency of medical prescriptions， SU Song of the Northern Song dynasty believed that the three were medicinal materials of different origins. In short， the names of the three have been unclear in history for a long time. According to the development of the time line， this paper examines the names and realities of the three， and concludes that the two（Weiwei and Weirui） are the same medicinal material， that is， Polygonatum odoratum of Liliaceae， and the Nyuwei is Clematis apiifolia of Ranunculaceae， and the source relationship of the three is clarified. The mainstream source of Yuzhu used in the past dynasties was the rhizome of P. odoratum， which was widely distributed in the wild and has a large amount of resources. The origins of Yuzhu recorded in ancient times were mainly Taishan in Shandong， Chuzhou and Shuzhou in Anhui， and Hanzhong in Shaanxi， in modern times， it was produced in northern Hebei and Shaoyang in Hunan with high quality， and in the modern times， Jiangbei Yuzhu from Haimen in Jiangsu， Anyuzhu from Nanling， Anqing and Tongling in Anhui， Guanyuzhu from Fengrun， Yutian， Zunhua， Huailai in Hebei and Suizhong， Jinxi， Jianchang， Lingyuan， Liaoyang， Haicheng， Gaiping in Liaoning， Xiangyuzhu from Shaoyang in Hunan are the authentic medicinal material. In ancient times， the quality of Yuzhu was good if it was fat and white， while in modern times， it is better with thick roots， bright yellow color， soft texture， no stiff skin and no oiliness. In ancient times， the origin processing of POR was mostly dried in the shade， but in modern times， it is mostly sun-dried or dried after steaming and rubbing. The ancient processing was mostly scraped off the skin and soaked in honey water and then steamed through， while the modern one is mostly washed and cut into thick slices for raw use. Based on the conclusion of the herbal textual research， it is suggested that the rhizome of P. odoratum of Liliaceae be used as the source for the development of famous classical formulas， and the corresponding specifications be selected according to the processing requirements of the prescription. In view of the Yiweitang in Wenbing Tiaobian， which uses the method of frying fragrance to achieve the effect of fragrant refreshing the spleen， it can be processed by referring to the stir-frying method in the current version of Chinese Pharmacopoeia.

Conclusion T he IB S scoring m ethod defined by the regulation has high detection efficiency and low false judgm ent rate, w hich provides a relatively conservative result. T he query table of IB S critical value for identification of full sibling detection sys-tem s w ith different num bers of ST R loci provides an im portant reference data for the result judgm ent of full sibling testing and ow ns a considerable practical value.
ABSTRACT
Objective To investigate the genetic polymorphism of 90 autosomal SNPs in Guangdong Han population and assess their value in forensic medicine based on next generation sequencing. Methods Blood samples were collected from 100 unrelated individuals. Through using AutoMate ExpressTM Nucleic Acid Extraction System, DNA was extracted. HID-Ion AmpliSeq? Identity Panel was applied for library preparation while Ion OneTouch? 2 system (OT2) was employed for emulsion PCR (emPCR). NGS was performed on the Ion PGM? system. Sequencing results were analysed using the Torrent Suite v4.4.2 with the HID_SNP_Genotyper v4.3.1 plugin. The forensic parameters were calculated and compared with GoldeneyeTM 20A systems. Results According to the Bonferroni correction, the genotypes of 90 autosomal SNPs were in accordance with Hardy-Weinberg equilibrium and no linkage disequilibrium was observed. The average Ho of 90 autosomal SNPs was 0.423, the average DP was 0.560 and the average PIC was 0.329. The CDP (cumulative power of discrimination) of 90 autosomal SNPs system was 1-1.20×10-33, which was greater than that of 20A System. The CPEtri (cumulative excluding probability of trio paternity) was 0.999 999 911 and the CPEduo (cumulative excluding probability of duo paternity) was 0.999 882. Both of these two parameters were below that of 20A System. Conclusion It suggested that the 90 autosomal SNPs System can be applied to forensic individual discrimination and trio paternity testing independently. Besides, it is supposed to be used in the duo paternity testing as an assistant measure.
ABSTRACT
Objective To explore the mutation of Y-STR loci in meiotic allelic transmission in a large pedigree. Methods The oral swabs of 163 male individuals were collected froma L in pedigree. Twenty-two Y-STR genetic markers were typed with AGCUY 24 fluorescent detection kit (AGCUY 24 sys-tem), which also contained 16 Y-STR markers included in Y filerTmmultiple amplification kit (Y filer system). The genotyping results of Y-STR loci were compared between each two males in the pedigree. Results There were 20 and 30 kinds of haplotypes obtained with Y filer and AGCUY 24 systems in 163 male individuals fromthe L in pedigree, respectively. The rates referred to haplotype differences (RRHD) of these two typing systems between male pairs were 0.910 5 and 0.922 7, respectively. The average number of marker differences were 6.582 1 and 9.824 8, respectively. The RRHDincreased along with the incidents of meiosis. Conclusion Y-STR mutation leads to different Y-STR haplotypes among the male members in a paternal pedigree and the rate of difference increases along with the incidents of meiosis.
