A direct current glow discharge mass spectrometry ( GD-MS) for the determination of Li, Be, Na, Mg, Si, P, K, Ca, Ti, V, Cr, Mn, Co, Ga, Sr, Mo, Ag, Cd, Sn, Sb, W and Pb in nickel-zinc ferrites was developed. Copper powder as the conductive medium was evenly mixed with nickel-zinc ferrites powder for tableting, and then the impurity elements in nickel-zinc ferrites were determined by GD-MS. The influence of sample preparation and the glow discharge conditions including discharge current, discharge voltage, discharge gas flow rate and pre-sputter time on discharge stability and analysis sensitivity were investigated. The mass spectrometry interferences of analytes were investigated, as well as appropriate isotopes were selected. Most of the mass spectrometry interferences were avoided by measuring in medium resolution mode and high resolution mode. Total signal of Fe, Ni, Zn, O and Cu normalization was adopted, and the impurity elements in nickel-zinc ferrites were calculate in subtraction. The results showed that the detection limits for the investigated elements were in the range of 0. 001-0. 29 μg/g, the relative standard deviations of each element were within 3 . 5%-18 . 6%. The analysis results were consistent with those obtained by inductively coupled plasma mass spectrometry.

Objective To establish the mouse model for human papillomavirus types 16, 45 and 58 by the corresponding pseudovirions. Methods The 293FT cells were co-transfected with eodon-modified HPV eapsids genes together with a reporter plasmid containing the luciferase gene. The cells were collected and lysed, then the pseudovirus was collected and the titration was performed. The mouse was subcutaneous-ly injected with Depo-Provera. After 4 d and intravaginally injected with nonoxynol-9, and 6 h later pseud-oviruses were inoculated in intravaginal. After 7 d, the mouse was instilled luciferin substrate intravaginally, and the expression level of the lueiferase gene was detected by the in vivo Imaging System (IVIS). Results Three types (HPV16, HPV45 and HPV58) of pseudoviruses had been produced and the titer was 3.7×108 TU/ml, 1.5×108 TU/ml and 1.2×108 TU/ml, respectively. The luminescent regions could be detected in the mice which were infected with the pseudovirions, the luminescent signal intensity for types 16,45 and 58 was 1.779×106p/s, 5.738×105×p/s and 1.829×106p/s, respectively. Conclusion The mouse models for HPV16, 45 and 58 have been successfully established based on pseudovirions, which will be very useful for the research of HPV infection intervention, the evaluation of HPV vaccines and the screening of the prophylactic agents.

Objective To assess the relationship between fruit intake and gastric cancer.Methods Articles published during January 2001 and October 2012 that assessed the relationship between fruit intake and gastric cancer were searched on PubMed,Ovid and Willey database.Adjusted relative risk (RR) and 95％ confidence intervals (CI) were calculated by using fixed-effect or random-effect model.Variants of subgroup analysis included living regions,followup duration,and adjusted factors.Results A total of 3679 gastric cancer patients and 1 173 859 subjects from 7 prospective cohorts were included in this metaanalysis,and the pooled RR was 0.89 (95％ CI:0.78-1.01).In the subgroup analysis,the pooled RR in the 10-year followup group was 0.94 (95％ CI:0.85-0.99) before age,cigarette smoking and alcohol drinking were adjusted (RR =0.81,95％ CI:0.54-0.99).Conclusion Fruit intake may prevent the development of gastric cancer.

Aim To study the function of VR1 in chronic pain, to construct VR1 siRNA expression vectors and to study their silencing effect in the DRG neurons of rats were detected.Methods The hairpin sequences of siRNAs targeting VR1 gene of rat were designed, and two pairs of oligonucleotide sequence were synthesized. The annealed oligonucleotide fragments were cloned into linearized pRNAT-U6.2/Lenti expression vector and identified by PCR and DNA sequencing.Then, they were co-transfected by lipofectamine into 293T cells.The silencing effects of the lentivector-mediated VR1 siRNAs on the expression of VR1 mRNA were determined by RT-PCR after intrathecal injection in rats.Results DNA sequencing showed that the oligonucleotide fragments were correctly cloned into linearized pRNAT-U6.2/Lenti expression vector and the expression of VR1 mRNA in L4-L6 DRG neurons was inhibited significantly by pRNAT-U6.2/Lenti-siVR1 after intrathecal injection in rats.Conclusion The lentivector-mediated siRNAs are successfully constructed and they inhibit the expression of VR1 mRNA in the DRG neurons of rats, which may provide a potential tool for the further study and treatment of chronic pain.

OBJECTIVETo verify 3 novel HLA-A alleles A*24:224, A*24:225 and A*24:257 identified in Chinese Han individuals.

METHODSNo full matched results were obtained at HLA-A locus in HLA typing for China Marrow Donor Program (CMDP) using bi-allelic Sequence-Based Typing (SBT). The novel HLA alleles were identified with allele-specific amplification SBT.

RESULTSAll of the three probands had a novel nucleotide sequence at HLA-A locus. All of the 3 new sequences are most close to HLA-A*24:02:01:01 except for 1 or 2 nucleotide substitution in exon 2, which resulted in different changes in corresponding codons and encoded amino acids.

CONCLUSIONThree novel HLA-A alleles were confirmed and officially named as HLA-A*24:224, HLA-A*24:225 and HLA-A*24:257 under the GenBank accession numbers JQ899198, JQ924283 and HG003642 by the WHO Nomenclature Committee for Factors of the HLA System in November 2012 and November 2013, respectively.

Objective To report a pedigree with X?linked dominant protoporphyria(XLDPP), and to detect 5?aminolevulinic acid synthetase 2(ALAS2)gene mutations in this pedigree. Methods A clinical investigation was performed in a pedigree with XLDPP, and relevant data were collected from family members. A next?generation sequencing method was applied to screen possible mutation sites, and Sanger sequencing was performed to determine pathogenic gene mutations. Dermoscopy was conducted to observe skin lesions in the patients with XLDPP, and the Fotofinder system and very high frequency (VHF) ultrasound system were utilized to assess the severity of photodamage. Liver and gallbladder ultrasonography as well as blood examination were performed for all the family members. Results A deletion mutation, c.1706?1709ΔAGTG, was detected in the ALAS2 gene on the X chromosomes of all the patients in this family, which led to replacement or loss of 19-20 C?terminal residues through transcriptional frameshifting, and eventually caused an increase in ALAS2 activity. In the patients with XLDPP, skin photodamage was relatively severe;protoporphyrin?induced hepatobiliary damage was observed and aggravated with age;anemia and iron deficiency occurred sometimes. Conclusion The deletion mutation c.1706?1709ΔAGTG of the ALAS2 gene may be the underlying cause of XLDPP in this pedigree.

Objective:To explore the effects of mothers' exposure to polycyclic aromatic hydrocarbons during pregnancy on their children's neurobehavioral development.Methods:In November 2009 to April 2010, a total of 221 pairs of mother-newborn pairs were recruited from two cooperative hospitals in Taiyuan, and their children were followed up at age two. High performance liquid chromatography was used to determine the level of BPDE-DNA in cord blood leukocytes. The Neonatal behavioral neurological assessment (NBNA) was used to assess the neurodevelopment of newborns, and the Gesell Development Scale was used to measure neurodevelopmental indexes of 2-year-old children. NBNA includes behavior, active and passive tone, primitive reflexes and general assessment, with a total score of 40 points. The Gesell Developmental Schedules consisted of four sub-scales: motor development, adaptive behavior development, language development and personal-social behavior development. We used mean and standard deviation to describe continuous variables with normal distribution, median (interquartile range) to describe continuous variables with skewed distribution, and frequency and proportion to describe categorical variables. Restricted cubic spline models were applied to assess the dose-response relationships between maternal prenatal polycyclic aromatic hydrocarbons exposure and children's neurobehavioral development at two years old. Generalized linear models were applied to evaluate the effect of exposure to maternal prenatal polycyclic aromatic hydrocarbons exposure on children's neurobehavioral development at 0 and two years old.Results:The NBNA score was 38.0±0.8, and the scores of 2-year-old children's motor, adaptive, language and personal-social were 111.6±15.0, 110.5±14.6, 108.8±17.2 and 111.7±14.5, respectively. After adjusting for confounding factors, there is no dose-response association between the cord blood BPDE of pregnant women and neonatal NBNA scores, but there were dose-response associations between BPDE and scores of 2-year-old children's motor, adaptive, language and personal-social. A unit increase in cord blood ln (BPDE-DNA), the score of motor, adaptive, language and personal-social of 2-year-old children decreased on average by 4.54、6.29、8.41 and 7.02 points.Conclusion:Maternal exposure to polycyclic aromatic hydrocarbons during pregnancy is associated with decreased children's neurobehavioral development at two years old.
