OBJECTIVE:
To study the forensic application of Goldeneye DNA ID 26Y Kit in the She nationality.
METHODS:
Through capillary electrophoresis, the genotype of 26 Y-STR loci were analyzed in 53 unrelated male individuals from Fujian She nationality. The population genetics parameters such as allele frequency and haplotype diversity were calculated. The comparisons among the She nationality and the other nationalities were analyzed.
RESULTS:
A total of 126 alleles were observed on the 26 Y-STR loci of 53 unrelated male individuals. The allele frequencies and GD value ranged from 0.010 1 to 0.886 8 and 0.211 2 to 0.846 2, respectively. The GD value was greater than 0.5 in the 19 loci. A total of 47 haplotypes were observed. Based on R(ST), multidimensional scaling plot indicated that the genetic relationship among Fujian She nationality and Minnan Han nationality was closest, followed by Southern China Han nationality and Northern China nationality.
CONCLUSION
Goldeneye™ DNA ID 26Y Kit including 26 Y-STR loci has good polymorphism in the She nationality. As an additional system, it has forensic application value in some special cases.

To clone the 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (TwMCT) full length cDNA from Tripterygium wilfordii, the specific primers were designed according to the transcriptome data and the LCPCR were carried out. After a series of bioinformatics analysis on the TwMCT, the MeJA induced expression content were investigated by real-time fluorescence quantification polymerase chain reaction (RT-qPCR). The result showed that the full of TwMCTcDNA was 1 318 bp nucleotides encoding 311 amino acids. The molecular weight of the deduced TwMCT protein was about 34.14 kDa and the theoretical isoelectric point was 8.65. Result of the RT-qPCR analysis indicated that the content of TwMCT mRNA expression in T. wilfordii suspension cell was rising after treating with MeJA and reached the maximum in 24 h. Cloning and analyzing TwMCT gene from T. wilfordii provided gene element for studying the function and expression regulation of secondary metabolites.

4.Epidemiological and clinical features of vaccine-preventable diseases in vaccine era.
Chinese Journal of Contemporary Pediatrics 2019;21(3):195-198
In countries and regions with high vaccination coverage, several vaccine-preventable diseases have been resurged in recent years, such as measles, varicella, pertussis and mumps. Some studies have found that the clinical manifestation and epidemiological characteristics of these diseases were different from those in pre-vaccine era. This article reviewed the clinical and epidemiological features of vaccine-preventable diseases before and after wide immunization implementation, focusing on the situation in China, in order to attract the attention of clinicians, raise awareness, strengthen prevention and control, and promote in-depth research for these diseases.

To exert pharmacological effects, no matter therapeutic effect or toxic/side effect, it's necessary to achieve enough plasma concentration. Chinese medical compounds, which contain various ingredients, influence the metabolism of some active ingredients through the interaction of ingredients to improve curative effects or reduce toxic/side effects. Pharmacokinetics can be used to explore how Chinese medical compounds influence the in vivo metabolism of some active ingredients to achieve better curative effects.

OBJECTIVETo screen the antisense oligodeoxynucleotides (asONs) which could hybridize with KDR (kinase insert domain-containing receptor) mRNA in an effective and specific way and to explore their anti-tumor effects on breast cancer MCF-7 cell line in vitro.
METHODSThe asONs were firstly selected using oligodeoxynucleotides library hybridization or computer prediction, then their hybridization ability with KDR mRNA was further tested with oligonucleotide microarray. The asONs with strong hybridization intensity were selected. Their inhibitory effects on MCF-7 cells proliferation and KDR expression were assayed by MTT, RT-PCR and Western blotting assay, respectively.
RESULTSIn 13 asONs selected with oligodeoxynucleotides library hybridization, 8 (8/13, 61.5%) showed strong hybridization signals, while such was only 1 in 17 asONs designed by computer prediction. 9 asONs with strong hybridization intensity were selected and synthesized with phosphorothioated modification. All these asONs inhibited the MCF-7 cells proliferation in a dose-dependent manner, in which asON4 and asON7 screened by oligodeoxynucleotides library in combination with oligonucleotide microarray were the most effective, with inhibitory rates of 51.6% and 62.2% at 0.8 micromol/L, respectively. The KDR expression at mRNA and protein levels was reduced by both the two asONs, in a dose-dependent manner.
CONCLUSIONasONs screened by oligodeoxynucleotides library hybridization are well consistent with that chosen with oligonucleotide microarray. The combination of oligodeoxynucleotides library with oligonucleotide microarray is an effective approach of asONs screening. The asONs targeting KDR mRNA showed prominent anti-tumor activity on breast cancer MCF-7 cells.

4-(Cytidine-5-diphospho) -2-C-methyl-D-erythritol kinase is a key enzyme in the biosynthesis pathway of terpenoids. According to the transcriptome database, the specific primers were designed and used in PCR. The bioinformatic analysis of the sequenced TwCMK gene was performed in several bioinformatics software. The Real-time fluorescence quantification polymerase chain reaction (RT-qPCR) were used to detect the expression levels of TwCMK from T. wilfordii after elicitor MeJA supplied. The results showed that the full length of TwCMK cDNA was 1 732 bp encoding 387 amino acids. The theoretical isoelectric point of the putative TwCMK protein was 5.79 and the molecular weight was about 42.85 kDa. MeJA stimulated the rising of TwCMK expression in suspension cell and signally impacted at 24 h. The research provides a basis for further study on the regulation of terpenoid secondary metabolism and biological synthesis.

Objective To study the infection status of HIV-1 among blood recipients from 1994 to 1998 in certain areas of Hebei province. Methods A general investigation was set up among all the people in 15 townships of certain areas from November 2003 to February 2005. An epidemiological investigation was conducted among people who had received blood from donors, during 1994 and 1998. Blood samples were collected. ELISA was used in preliminary screening and Western-blot (WB) was used among people who showed a positive result in the preliminary screening. Results The infection rate of HIV-1 after blood receipt was 15.54% (92/592) , and the infected persons were all appeared in five medical centers of 6 townships which located at the west part of the area. HIV-1 infection happened over the years, and reaching the zenith in the year 1995. Most of the infected persons were young women. Procreation was the main cause of blood transfusion for women and trauma was for men. Conclusion A typical HIV outbreak happened in certain areas after blood transfusion in Hebei.
