Form Gene Clustering Method about Pan-Ethnic-Group Products Based on Emotional Semantic

The use of pan-ethnic-group products form knowledge primarily depends on a designer＇s subjective experience without user participation. The majority of studies primarily focus on the detection of the perceptual demands of consumers from the target product category. A pan-ethnic-group products form gene clustering method based on emotional semantic is constructed. Consumers＇ perceptual images of the pan-ethnic-group products are obtained by means of product form gene extraction and coding and computer aided product form clustering technology. A case of form gene clustering about the typical pan-ethnic-group products is investigated which indicates that the method is feasible. This paper opens up a new direction for the future development of product form design which improves the agility of product design process in the era of Industry 4.0.

Correlation between the Xba Ⅰ polymorphism of apoB gene and serum lipid profiles in Li ethnic group

Objective:To study correlation between the Xba I polymorphism of apoB gene and plasma lipid profiles in Li ethnic group.Methods:Total 1S1 cases of healthy Li people were recruited randomly by cluster sampling and 200 Han people were recruited as control;blood was drawn to analyze Xba I polymorphism distribution of apoB gene and serum lipid levels.Results:There were lower serum total cholesterol(TC)and low density lipoprotein cholesterol(LDL-C)levels in serum of Li people;while,high density lipoprotein cholesterol(HDL-C),X^-/X^-genotype and X^+allele frequencies exhibited higher levels than Han people.Interestingly,HDL-C level was reduced,while LDL-C level was enhanced in subjects carrying heterozygous(X^-/X^-)genotype compared to homozygous(X^-/X^-)genotype.Additionally,there were no difference in serum level of triglyceride,TC,apoprotein A(apo A)and apoprotein B(apo B)between Li and Han people,the same results were showed between X^-/X^+and X^-/X^-genotype carriers.Conclusions:XbaⅠpolymorphism of apoB gene is correlated to the profiles of serum lipid level,X^-/X^+genotype carriers are phenotyped with higher LDL-C level and lower level of HDL-C in Li ethnic group.

Observation on Baseline Sensitivity of <i>Erysiphe necator</i>Genetic Groups to Azoxystrobin

Powdery mildew, caused by Erysiph necator, is a common and severe fungal disease of grapevine all over the world. The disease costs millions of dollars to vine growers, due to intensive use of fungicides and yield losses. Recently in population of E. necator two genetic groups have been described, the two groups seem to occupy different temporal niches, with a temporal alternation that is clear-cut in vineyards intensively treated with chemical fungicides. QoI-STAR (Quinol Outside Inhibitors-Strobilurin Type of Action and Resistance) fungicides are widely used to control the disease, and generally carry a high risk of pathogen resistance development. To clarify the behaviors of the biotrophic fungus when treated with azoxystrobin as a representative of QoI-STAR, baseline sensitivity of laboratory isolates were determined. A leaf bioassay and the primers RSCBF1 and RSCBR2 designed on the highly conserved regions of cytb gene in fungi were used. Partial sequence of E. necator cytb gene were obtained. Attempts to obtain a laboratory mutant were not totally successful. The sensitivity to azoxystrobin (EC50) in isolates of genetic group B was significantly higher than in isolates of group A, to which all the isolates collected later in the season belonged. The higher sensitivity to azoxystrobin fungicides observed in group B isolates can be at the basis of their precocious disappearance in vineyards, and can have important implications for powdery mildew control strategies.

Polycomb Group蛋白复合体与干细胞的发育调控

Polycomb group(PcG)蛋白是表观遗传调控因子中一个非常重要的家族,参与维持特定基因的沉默,在调控干细胞增殖与分化的过程中起着非常重要的作用。PcG蛋白可通过形成不同的蛋白复合物引起不同的染色质修饰来调控干细胞的生命活动,其复合物主要包括两个重要的表观遗传调控因子:PRC1(polycomb repressive complex 1)和PRC2(polycomb repressive complex 2)。为了阐明PcG蛋白在干细胞增殖与分化中的调控作用,本文分别从PcG蛋白复合体的组成、在靶基因中的定位、募集和在干细胞发育中的调控等方面进行了综述,旨在为进一步研究干细胞的发育调控机制提供理论依据。

Xeroderma pigmentosum group D 751 polymorphism as a predictive factor in resected gastric cancer treated with chemo-radiotherapy

AIM: To evaluate the potential association of xeroderma pigmentosum group D (XPD) codon 751 variant with outcome after chemo-radiotherapy in patients with resected gastric cancer. METHODS: We used PCR-RFLP to evaluate the genetic XPD Lys751Gln polymorphisms in 44 patients with stage Ⅲ (48%) and Ⅳ (20%) gastric cancer treated with surgery following radiation therapy plus 5-fluorouracil/ leucovorin based chemotherapy. RESULTS: Statistical analysis showed that 75% (12 of 16) of relapse patients showed Lys/Lys genotype more frequently (P = 0.042). The Lys polymorphism was an independent predictor of high-risk relapse-free survival from Cox analysis (HR: 3.07, 95% CI: 1.07-8.78, P = 0.036) and Kaplan-Meir test (P = 0.027, log-rank test). CONCLUSION: XPD Lys751Gln polymorphism may be an important marker in the prediction of clinical outcome to chemo-radiotherapy in resected gastric cancer patients.

A Novel NR0B1 Gene Mutation Causes Different Phenotypes in Two Male Patients with Congenital Adrenal Hypoplasia

X-linked congenital adrenal hypoplasia is characterised by the acute onset of primary adrenal insufficiency in infancy or early childhood and hypogonadotropic hypogonadism(HH)at puberty,arising from mutations of the nuclear receptor subfamily 0 group B member 1(NR0B1)gene.This study investigated an extended family with two affected males(patient A:23 years and patient B:2 months old)and three carrier females.Sequencing analysis of the NR0B1 gene coding region from the family revealed a novel hemizygous deletion[c.604delT;p.(C202Afs*62)]in the two male patients.Furthermore,the patients'respective mothers and their common grandmother had this heterozygous mutation,but it was not present in the Human Gene Mutation Database.The two male patients showed inconsistent clinical features at onset,particularly in early childhood;however,it is possible that the younger patient will eventually show a delay of puberty,feminisation,and nonspermatogenesis in adulthood,similar to that in the older patient.Identification of a novel NR0BI mutation in this family is important for the diagnosis and genetic counselling of children with primary adrenal insufficiency and HH,and will be helpful for predicting long-term clinical symptoms.

DNA repair gene XRCC1 polymorphisms and susceptibility to childhood acute lymphoblastic leukemia: a meta-analysis

Objective： To estimate the relationship between genetic polymorphisms of X-ray repair cross- complementing group 1 （XRCC1） and the susceptibility to childhood acute lymphoblastic leukemia （ALL）. Methods： Relevant case-control studies were enrolled in the meta-analysis. We applied Rev Man 4.2 software to pool raw data and test studies＇ heterogeneity and to calculate the incorporated odds ratio （OR） and 95% confidence interval （95% CI）. Results： Our data showed that the OR for the Gln allele of the Arg399Gln polymorphism, compared with the Arg allele, was 1.35 （95% CI, 1.16-1.57; P〈0.0001） for childhood ALL patients. Similarly, the homozygous genotype Gln/Gln and heterozygous genotype Arg/Gln both significantly increased the risk of childhood ALL compared with the wild genotype Arg/Arg （OR =1.58; 95% CI, 1.13-2.21; P=0.008; OR =1.51; 95% CI, 1.21-1.87; P=0.0002）. The dominant model of Arg399Gln was associated with childhood ALL risk （OR =1.54; 95% CI, 1.25-1.89; P〈0.0001）. The ethnic subgroup analysis demonstrated that the Gln allele in all five ethnic groups was prone to be a risk factor for childhood ALL just with different degrees of correlation while Arg194Trp SNP showed a protective or risk factor or irrelevant thing in different races. Conclusions： XRCC1 399 polymorphism may increase the risk of childhood ALL. Different ethnic groups with some gene polymorphism have different disease risks.

Correlation between X-ray cross-complementing group 1 polymorphisms and the onset risk of glioma A meta-analysis

OBJECTIVE： To evaluate the association of X-ray cross-complementing group 1 （XRCC1） Arg399GIn, Arg194Trp and Arg280His polymorphisms with the risk of glioma. DATA SOURCES： A systematic literature search of papers published from January 2000 to August 2012 in PubMed, Embase, China National Knowledge Infrastructure database, and Wanfang da- tabase was performed. The key words used were ＂glioma＂, ＂polymorphism＂, and ＂XRCC1 or X-ray repair cross-complementing group 1＂. References cited in the retrieved articles were screened manually to identify additional eligible studies. STUDY SELECTION： Studies were identified according to the following inclusion criteria： case-control design was based on unrelated individuals; and genotype frequency was available to estimate an odds ratio （OR） and 95% confidence interval （CI）. Meta-analysis was performed for the selected studies after strict screening. Dominant and recessive genetic models were used and the relationship between homozygous mutant genotype frequencies and mutant gene frequency and glioma incidence was investigated. We chose the fixed or random effect model according to the heterogeneity to calculate OR and 95%CI, and sensitivity analyses were conducted. Publication bias was examined using the inverted funnel plot and the Egger＇s test using Stata 12.0 software. MAIN OUTCOME MEASURES： Association of XRCC1 Arg399GIn, Arg194Trp, and Arg280His polymorphisms with the risk of glioma, and subgroup analyses were performed according to differ- ent ethnicities of the subjects.RESULTS： Twelve articles were included in the meta-analysis. Eleven of the articles were concerned with the Arg399GIn polymorphism and glioma onset risk. Significantly increased glioma risks were found only in the dominant model （Gin/Gin ＋ GIn/Arg versus Arg/Arg： OR = 1.26, 95%CI= 1.03-1.54, P = 0.02）. In the subgroup analysis by ethnicity, significantly increased risk was found in Asian subjects in the recessive （OR = 1.46, 95%CI= 1.04-2.45, P = 0.03） and dominant models （OR = 1.40, 95%CI= 1.10-1.78, P = 0.007）, and homozygote contrast （OR = 1.69, 95%CI= 1.17-2.45, P = 0.005）, but not in Caucasian sub- jects. For association of the Arg194Trp （eight studies） and Arg280His （four studies） polymorphisms with glioma risk, the meta-analysis did not reveal a significant effect in the allele contrast, the recessive genetic model, the dominant genetic model, or homozygote contrast. CONCLUSION： The XRCC1 Arg399GIn polymorphism may be a biomarker of glioma susceptibility, espe- cially in Asian populations. The Arg194Trp and Arg280His polymorphisms were not associated with overall glioma risk.
