One type of important plant disease resistance, gene-for-gene resistance, is resulted from the interactions between products of the pathogen avirulence (Avr) genes and their matching plant resistance (R) genes. Avr genes have been cloned from a variety of pathogens including fungi, bacteria, viruses and oomycetes. No significant homology is found between sequences of the most cloned Avr genes and those of known proteins or between those of themselves. However, significant homology has been found between sequences of the cloned R genes and those of known proteins or between those of themselves. R proteins consist of similar domains. It has been reported that hypersensitive cell death and resistance, which are induced by interactions between products of different Avr/R gene pairs consisting of similar R genes but different Avr genes, are distinct in development speed, strength, and organ and tissue specificity. Avr genes have dual functions: Pathogens containing Avr genes are avirulent to plants carrying the matching R genes, while they are virulent in race, strain, pathovar or species-specific way to plants without carrying the matching R genes.

The NPRI (nonexpressor of pathogenesis-related genes (1) gene, firstly cloned in Arabidopsis thaliana, is a key gene involved in regulation of plant disease resistance. It plays a pivotal role not only in systemic acquired resistance (SAR) and induced systemic resistance (ISR), but also in basic resistance and resistance (R) gene-dependent resistance. NPR1 monomerization induced by enhanced reducing condition after oxidative burst, and the accumulation of NPR1 monomers in the nuclei, are required and enough for expression of PR (pathogenesis-related) genes and SAR. NPR1 regulates PR gene expression through interaction with TGA transcription factors (TF). As a cross-talk point of a variety of defense signaling pathways, probably through direct or indirect interacting with some WRKY TFs and a NPR1-like protein NPR4, NPR1 is essential in balancing salicylic acid- and jasmonic acid- dependent signal transduction pathways, which is achieved through an unknown mechanism in the cytosol. The possible application of NPR1 in plant protection is also discussed in this review.

Objective To investigate immunological relationship between early induction of food allergy and occurrence of later asthma in mice, and explore the pathological changes in lung tissues. Methods Thirty-seven female BALB/c mice aged 6 weeks were randomly divided into blank control group ( n = 12), food allergy group ( n = 13) and asthma group (n = 12). After being challenged by ovalbumin (OVA), the levels of serum IgE, IL-4 and INF-γ in bronchoalveolar lavage fluid ( BALF) were detected. The numbers of inflammatory cells and eosinophils ( EOS) in BALF were counted. Lung tissues were obtained for pathological sections, and thickness of bronchial wall and EOS infiltration were observed. Results The level of serum IgE and level of IL-4, ratio of IL-4/IFN-γ and number of EOS in BALF in food allergy group and asthma group were significantly higher than those in control group (P <0.05). The level of IL-4 and number of EOS in BALF in asthma group were significantly higher than those in food allergy group (P <0.05) , while there was no significant difference in serum IgE level between these two groups (P > 0.05), and levels of IFN-7 in BALF in both groups were significantly lower than that in blank control group (P<0.05). There were more EOS infiltration in lung tissues and thicker bronchial wall in food allergy group and asthma group than that in blank control group (P < 0.05), and the number of EOS in asthma group was significantly higher than that in food allergy group ( P < 0.05). Conclusion IgE-mediated immune response is involved in both food allergy and asthma mouse models. Lung immune imbalance of Thl/Th2 and inflammatory cell infiltration caused by food allergy may participate in the occurrence of later asthma.

Objective To study the effects of IL-4 in prostate cancer cells glycometabolism and proliferation. Methods We used IL-4 to treat PC3 cells, then tested the changes of LDH-A expression by RT-qPCR, Western Blot, CCK-8 and lactate production assay. Results Our data showed that IL-4 induced LDH-A up-expression in PC3 cells at mRNA and protein levels. Also, IL-4 promoted the proliferation activation and increased lactate production in PC3 cells. Conclusion IL-4 can strengthen the proliferation activation in PC3 cells by up-regulating LDH-A expression.

BackgroundIt is important to measure the corneal curvature, anterior chamber depth (ACD) and axial length accurately for calculating IOL power. The interchange outcomes from different measuring methods and apparatus will cause unreliable IOL power. ObjectiveThe present study was to compare the differences of corneal curvature, anterior chamber depth (ACD) measured by IOLMaster and Orbscan Ⅱbefore and after laser in situ keratomileusis(LASIK) and further compare the axial length measured by IOLMaster and A-ultrasound. Methods One hundred and thirty eyes from 65 consecutive myopic patients before LASIK and 56 eyes of 28 cases with 1-month follow-up duration after LASIK in Henan Eye Institute were enrolled in this study. The K value, ACD between IOLMaster and Orbscan Ⅱ as well as results of axial length between IOLMaster and A-ultrasound were compared by using paired t test. The agreements of the measured values among IOLMaster, Orbscan Ⅱ and A-ultrasound were evaluated using Bland-Altman plot. ResultsBefore LASIK,the K value measured by IOLMaster,Orbscan Ⅱ were ( 43.32 ± 1.52 ) D and ( 42.99 ± 1.45 ) D respectively with the difference value of( 0. 33 ±0. 03 ) D, showing a significant difference(t=10. 380,P=0.000) and a positive relation between them(r=0.971,P=0.000). After LASIK,the K value measured by IOLMaster, Orbscan Ⅱwere(39. 02±2. 14) D and ( 38.91 ±2. 04) D with the difference value (0. 12±0. 33 ) D, presenting a significant differences between them (t =2.715, P =0.009). Bland-Altman plots indicated the disagreement in K value and uninterchangeable. Before LASIK, the ACD measured by IOLMaster,Orbscan Ⅱ and A-ultrasound were ( 3.72 ± 0. 22 ) mm, ( 3.69 ±0. 22 ) mm and ( 3.75± 0.27 )mm respectively and no significant differences were found between them (P ＞ 0. 05 ). Axial length measured by IOLMaster significantly prolonged in comparison with A-ultrasound(25.59± 1. 01 mm vs 25.22±0.99 mm ) , and the difference was( -0. 37 ±0. 30 ) mm, showing significant difference ( t =- 14. 098, P =0. 000 ) and positive correlation ( r =0. 954, P =0. 000 ). Axial length values measured by IOLMaster were ( 25.54 ± 1.05 ) mm in preoperation and ( 25.48 ± 1.01 ) mm in postoperation with the difference (0.052±0. 412)mm, showing statistically insignificant difference between them (t=0. 946,P=0. 348). ConclusionsKeratometries measured by IOLMaster,Orbscan Ⅱ are much more different. Therefore,these two methods are not recommended to use interchangely. ACD measured by IOLMaster,Orbscan Ⅱ and A ultrasound are proved to obtain the similar results and is clinically interchange. Axial length measured by IOLMaster is longer than that measured by A-ultrasound.

Objective To evaluate the diagnostic value of urine Cystatin C(Cys C) for renal function impairment in neonates with hypoxic-ischemic encephalopathy(HIE).Methods The urine Cys C concentration was measured by enzyme linked immunosorbent assay(ELISA) in 47 cases of HIE newborns(25 cases were mild HIE and 22 cases were moderate-severe HIE) within 3 days after their birth.Twenty-three cases without perinatal asphyxia or other factors which could result in renal function impairment were selected as control group.Urine Cys C with urine retinal-bindingprotein(RBP),?2-microglobulin(?2-MG) and fractional sodium excretion(FENa%) were analyzed by kolmogorov-smirno in each group.Results Compared with control group,the concentration of urine Cys C,RBP and the levels of FENa% in HIE newborns were significantly elevated.The levels of urine Cys C in moderate-severe HIE newborns were significantly higher than those in mild HIE newborns(Pa

Objective To learn the current neglected situation and its impact factors on rural children in two provinces in Western China.Methods The investigation was conducted by using multistage stratified cluster sampling method in some parts of the Shaanxi province and the city of Chongqing.Results 1488 subjects,aged from 0 to 6,were recruited in the present study.Results showed that the total prevalence rates of neglected rural children in the two research sites were 31.59％ and 48.32 respectively.No significant difference was found on the prevalence of neglected for boys and girls ( x2 =0.86,U=1.51,P ＞ 0.05 ).The degrees of negligence in the older children showed a significant increase than in the younger children (x2 =13.36,F=33.45,P＜ 0.05 ).The prevalence and degree of negligence in families with three generations were lower than that of a single-parent families and remarried families (H=10.03,F=2.83,P＜0.05).The one-child-families were significantly lower than multiple children families,both in terms of prevalence and degree of negligence.Our data demonstrated the degrees of negligence in children whose parents were away from home,were higher than the children whose parents stayed with them ( x2=30.30,U=6.76,P＜0.05).The degree of negligence in Shaanxi was lower than that in Chongqing (x2=9.42,U=8.40,P＜0.05).Based on multivariate non-conditional logistic regression analysis,the determinants of stunting among the stranded children were as follows:parents were away from home (OR=1.54,95％ CI:1.20-1.97) ;structure of the family (OR=1.38,95％ CI:1.16-1.65) ; father' s occupation (OR=0.87,95％ CI:0.78-0.97) ; schooling of the children' s mother (OR=1.27,95％CI:1.07-1.52) ; relationship between children and their fathers (OR =1.43,95％ CI:1.07-1.91 ) etc.Conclusion The situation of negligence in children living in the rural areas,were serious in Shaanxi and Chongqing provinces,which called for the strengthening on the publicity and education of the issue.School and the society should also pay more attention to this problem.
