ABSTRACT
Panax ginseng(PG)and Panax notoginseng(PN)are highly valuable Chinese medicines(CM).Although both CMs have similar active constituents,their clinical applications are clearly different.Over the past decade,RNA sequencing(RNA-seq)analysis has been employed to investigate the molecular mechanisms of extracts or monomers.However,owing to the limited number of samples in standard RNA-seq,few studies have systematically compared the effects of PG and PN spanning multiple conditions at the transcriptomic level.Here,we developed an approach that simultaneously profiles transcriptome changes for multiplexed samples using RNA-seq(TCM-seq),a high-throughput,low-cost workflow to molecularly evaluate CM perturbations.A species-mixing experiment was conducted to illustrate the accuracy of sample multiplexing in TCM-seq.Transcriptomes from repeated samples were used to verify the robustness of TCM-seq.We then focused on the primary active components,Panax notoginseng sa-ponins(PNS)and Panax ginseng saponins(PGS)extracted from PN and PG,respectively.We also char-acterized the transcriptome changes of 10 cell lines,treated with four different doses of PNS and PGS,using TCM-seq to compare the differences in their perturbing effects on genes,functional pathways,gene modules,and molecular networks.The results of transcriptional data analysis showed that the tran-scriptional patterns of various cell lines were significantly distinct.PGS exhibited a stronger regulatory effect on genes involved in cardiovascular disease,whereas PNS resulted in a greater coagulation effect on vascular endothelial cells.This study proposes a paradigm to comprehensively explore the differences in mechanisms of action between CMs based on transcriptome readouts.
ABSTRACT
Objective To construct a database for the genetic polymorphism of 19 STR loci in Han population from Hainan province. To investigate the application of 19 STR loci in the paternity testing. Methods The genotypes of 462 unrelated individuals in Hainan were detected with GoldeneyeTM 20A PCR Amplification Kit. 19-STR database was acquired, analyzed and evaluated in 283 paternity testing cases. Results No deviations of allele frequency from Hardy-Weinberg equilibrium expectations were found for Chi-square test (P>0.05). Observed heterozygosity (Hobs) varied between 0.603 and 0.914, total discrimination power (TDP) of 19 STR loci was more than 0.999999999999999, cumulative probability of exclusion (CPE) for triplet cases was 0.999999994. In all 283 paternity testing cases, triplets and duos were 170 and 113 respectively; there were 36 (12.7%) excluded cases comparing to 247 confirmed cases (87.3%). 14 mutation events were observed, and all were one-step mutation. Conclusion 14 out of 19 loci showed highly polymorphic in Han population from Hainan, and 19 STR system has high cumulative probability of exclusion and can meet the needs of paternity test of the local region. But mutation should be paid special attention to.
ABSTRACT
Objective To summarize the previous work experience and loss of function in the development process of hospital modernization of sterile supply room,and discuss the model of centralized treatment and unified supply.Methods Through investigation in the clinical departments,various roles and regulations of sterile supply room were established,especially the various job responsibilities,operating procedures,disinfection and isolation system,the quality management system,testing system,equipment and apparatus management systems,traceability systems,continuous quality improvement process and goods recall system.The system had performance appraisal,workilow management and other methods to enhance the staff's self-discipline,to strengthen humanities education for sterile supply room staff,strict execution of the standards and norms of Health Ministry,to enhance the legal awareness,establish and improve the sterile supply room management systems and service system.Results Implementation of centralized treatment can effectively prevent nosocomial infection,reduce the spread of pollution to ensure medical safety,reduce staff input that help ensure the professional quality and reduce the economic costs,and promote the professional development of sterile supply.Conclusions Centralized treatment of multiplexing medical apparatus and instruments promotes the all-dimensional development of sterile supply room,which is worthy of wide application.
ABSTRACT
Objective To investigate the genetic polymorphisms of 9 STR loci in Guangdong Han population, Guangxi Han population, Dong population, Zhuang population, and Miao population. Method DNA samples from 328 unrelated individuals in Guangdong Han population and Guangxi Han Population, 199 Zhuang popultion, 162 Dong population, 194 Miao population were screened by using AmpFISTR Profiler PlusTM PCR Amplification Kit and 3100 Genetic Analyzer. Results The genotype frequencies of these 9 STR loci meet the Hardy - Weinberg expectations.The matching probabilities of these 9 STR loci were between 1.51 x 10-11- 8.08 x 10-11 .The cumulative exclusion chances of paternity were 0.99981 - 0.99990. Conclusion Our results showed that the The Profiler Plus?PCR Amplification systems of 9 STR loci are useful in forensic case work in Guangdong Han population, Guangxi Han population, Dong population,Zhuang population and Miao population.
ABSTRACT
Objective To study the genetic polymorphism of 15 STR loci of 3 populations in Guangxi province. Methords DNA samples of unrelated individuals from 314 Gelao population,332 Mulao population,238 Yao population were analyzed using AmpFlSTR IdentifilerTM PCR Amplification Kit and 3100 Genetic Analyzer. Results The matching probability of the 15 STR loci was 1.839 ?10-16 ~ 5.073 ? 10 -17 and combined paternity of exclusion was 0.9999983 ~ 0.9999991 in the 3 populations. Conclusion The results showed that the 15 STR loci in Identifiler?PCR Amplification systems were useful for forensic case works in Gelao population, Mulao population and Yao population .
ABSTRACT
Objective To evaluate the power of the PowerPlex?6 system for paternity testing. Method 633 cases of paternity testing were studied. After the megaplex STR amplification, the PCR products were genotyped by using the ABI377 DNA Sequencer. Results Among the 879 unrelated individuals, 197 alleles and 739 different genotypes were observed. The cumulated discriminating power was 1x 10-30. And the cumulative chance of exclusion was 0.999999999999987. 95 out of 633 cases were excluded. The RCP of all unexcluded cases were ≥0.9990. Gene mutations were found in 19 cases. Conclusion The Po-werPlex?16 system is powerful and reliable for paternity testing.
