Functional analysis of control genes is playing an important role in animal development.The research is mainly focused on developing a method of estimating the gene's effect or function in the development of animals.In this article,the gene's expression and control are described by models of quantitative genetics,which include the genetic models about the genes with no interaction and interaction effect.On this basis,a method analyzing the functions of control genes in batches is advanced,the method includes three steps as follows: Firstly,describe the gene's expression and control with multiple regression models in statistic method in different conditions.Secondly,collect the material of gene's polymorphism related to the gene's expression and control.Because,gene's polymorphism or the codominant molecular marker electropherogram in a gene locus present 3 states,and can be expressed with -1,0 and 1 respectively.The author thinks it can be regarded as levels in orthogonal layout.Discard the materials of gene's polymorphism not fitting the orthogonal layout,and use the materials of gene's polymorphism fitting the orthogonal layout as the data to estimate the gene's effects.Thirdly,analyze the gene's effect or function with equations as follows:suppose that a quantitative trait is controlled by N gene loci,in each locus there are two alleles,the alleles' effects are A GM1 ?a GM1 ;A GM2 ? a GM2 ;...;A GMi ?a GMi ;...;A GMN ;a GMN units respectively.When the genotype in a locus is heterozygous A GMi a GMi ,the interaction coefficient of alleles in a locus is K units.If there is no interaction among different gene loci,the author thinks,the gene's effects and gene's type can be estimated by using such equation: P GM =2∑Ni=1(A i-a i+K i)+∑Ni=1(A i-a i)M GMi -∑Ni=1K GMi M GMi 2 If there are interactions among different gene loci,and the effect of the x th gene's state combined with the y th gene's state in the k th gene group is defined as Y xyr ,and let gene group electropherogram states be r (where r∈ ),the author thinks,the gene group's effects can be estimated by the equation: Y xyr = K PCxy0 +K PCxy r+K PCxy' r 2+K PCxy'' 3+K PCxy(3') r 4+K PCxy(4') r 5+K PCxy(5') r 6+K PCxy(6') r 7+K PCxy(7') r 8 If there are interactions among more genes,the analogous method can also be used. In this way,be using the gene's codominent marker materials fitting the orthogonal layout,the gene's expression and control can be researched by the method of multiple regression,the gene's relative effect can be estimated,the overdominant gene's overdominant coefficient can be assessed,the gene's type can be identified,the interaction gene group's relative effect and the interaction gene's relation can be estimated as well,and furthermore,the gene's relation can be expressed in equations.For the sake of understanding the method used in this paper,the rout to prove it is given as well.Finally,the author thinks,this method is very useful to research the gene's function in molecular developmental biology. 展开更多

The pathophysiology of IBS is complex and still incompletely known. Both central and peripheral factors, including psychosocial factors, abnormal GI motility and secretion, and visceral hypersensitivity, are thought to contribute to the symptoms of IBS. Several studies have demonstrated altered GI motor function in IBS patients and the pattern differs between IBS subgroups based on the predominant bowel pattern. Few studies have so far addressed GI secretion in IBS, but there are some evidence supporting altered secretion in the small intestine of IBS patients. Visceral hypersensitivity is currently considered to be perhaps the most important pathophysiological factor in IBS. Importantly, several external and internal factors can modulate visceral sensitivity, as well as GI motility, and enhanced responsiveness within the GI tract to for instance stress and nutrients has been demonstrated in IBS patients. Today IBS is viewed upon as a disorder of dysregulation of the so-called brain-gut axis, involving abnormal function in the enteric, autonomic and/or central nervous systems, with peripheral alterations probably dominating in some patients and disturbed central processing of signals from the periphery in others. 展开更多

Polar auxin transport plays a divergent role in plant growth and developmental processes including root and embryo development, vascular pattern formation and cell elongation. Recently isolated Arabidopsis pin gene family was believed to encode a component of auxin efflux carrier (G(?)lweiler et al, 1998). Based on the Arabidopsis pin1 sequence we have isolated a Brassica juncea cDNA (designated Bjpin1), which encoded a 70-kDa putative auxin efflux carrier. Deduced BjPIN1 shared 65% identities at protein level with AtPINl and was highly homologous to other putative PIN proteins of Arabidopsis (with highest homology to AtPIN3). Hydrophobic analysis showed similar structures between BjPINl and AtPIN proteins. Presence of 6 exons (varying in size between 65 bp and 1229 bp) and 5 introns (sizes between 89 bp and 463 bp) in the genomic fragment was revealed by comparing the genomic and cDNA sequences. Northern blot analysis indicated that Bjpin1 was expressed in most of the tissues tested, with a relatively higher level of transcript in flowers and a lower level in root tissues. Promoter-reporter gene fusion studies further revealed the expression of Bjpin1 in the mature pollen grains, young seeds, root tip, leaf vascular tissue and trace bundle, stem epidermis, cortex and vascular cells. BjPINl was localized on the plasma membrane as demonstrated through fusion expression of green fluorescent protein (GFP). Auxin efflux carrier activity was elevated in transgenic Arabidopsis expressing BjPIN1. 展开更多

The 11th Five Year Plan has divided national functional zones in the basic unit of county-level administrative region.After implementation of national Major Function-oriented Zones (MFOZ) at prefecture and county levels,the spatial development sequence must be specified,development intensity must be limited,oriented zones must be designated and "red line" areas of spatial governance must be defined.In view of the above,choosing a typical county area and exploring its functional zoning after orienting its major functions will supply reference for carrying out the national spatial planning in the 12th Five Year Period,and it will also provide experience for the study of function regionalization which is the theme of MFOZ in the present academic circles.In this paper,the authors take Shangyu County as an example to study the general principles,train of thought of county-level functional regionalization in development-optimized areas,and to explore its reasonable functional zoning plan.Consequently,the authors present five principles and suggest a function-oriented zoning plan with 2 levels and 4 types. 展开更多

Objective Typically,the transcranial approach has been used for the treatment of craniopharyngiomas with suprasellar extension,whereas the transsphenoidal approach has been used mostly for infradiaphragmatic craniopharyngioma.Total resection of craniopharyngioma can reduce the recurrence rate,especially in young children,but it may lead to severe complications.Therefore,any benefit of the degree of resection must be weighed against the risk of complications by the surgeons.The purpose of this study was to explore the therapeutic outcome after transsphenoidal microsurgical treatment of infradiaphragmatic craniopharyngioma and share our experiences.Methods Between January 2003 and June 2013,30 patients with infradiaphragmatic craniopharyngioma underwent transsphenoidal microsurgical resection in our hospital.The neurological,visual,and endocrine functions,and extent of resection were analyzed retrospectively.Recurrence or growth of residual tumor tissue during follow-up was assessed using magnetic resonance imaging(MRI).Results Total resection was achieved in 25 patients(83.3%),subtotal resection was achieved in 4 patients(13.3%),and partial resection was achieved in 1 patient(3.4%).There were no perioperative deaths.Cerebrospinal fluid(CSF) leakage occurred in 6 patients,and among them,2 required surgical repair of the sella.New-onset postoperative diabetes insipidus(DI) developed in 8 patients.Vision and visual fields were improved at different levels in 13 out of 16 patients who had sight impediments before treatment.Tumor recurrence and regrowth was observed in 2 patients;1 patient underwent transsphenoidal reoperation,the condition of the other patient who had undergone several craniotomies grew worse over the 6-month follow-up period.Conclusion Transsphenoidal surgery is an ideal choice in treating infradiaphragmatic craniopharyngioma.The transsphenoidal approach,which preserves pituitary function and avoids damage to the hypothalamic structures and optic nerve,is associated with fewer complications than the transcranial approach and a low mortality rate. 展开更多

A distributed local adaptive transmit power assignment (LA-TPA) strategy was proposed to construct a topology with better performance according to the environment and application scenario and prolong the network lifetime.It takes the path loss exponent and the energy control coefficient into consideration with the aim to accentuate the minimum covering district of each node more accurately and precisely according to various network application scenarios.Besides,a self-healing scheme that enhances the robustness of the network was provided.It makes the topology tolerate more dead nodes than existing algorithms.Simulation was done under OMNeT++ platform and the results show that the LA-TPA strategy is more effective in constructing a well-performance network topology based on various application scenarios and can prolong the network lifetime significantly. 展开更多

Objective The resting-state functional magnetic resonance imaging(rs-f MRI)method was used to observe brain activity and its functional connection upon electroacupuncture stimulation at bilateral uterine acupoints(EX-CA1),as well as to investigate the mechanism of acupuncture in the treatment of gynecological diseases.Methods Twenty-two healthy female subjects were stimulated by electroacupuncture at bilateral uterine acupoints;rs-f MRI data of the brain were acquired and standardized.Degree centrality(DC),amplitude of low-frequency fluctuation(ALFF),and regional homogeneity(ReHo)were used to analyze local spontaneous brain activity via acupuncture.An independent component analysis was used to evaluate the functional connectivity of the resting brain networks after acupuncture.Results Analytical results showed that the neural activity intensity of the precuneus lobe,orbitofrontal cortex,lingual gyrus,amygdala,and posterior central gyrus decreased after acupuncture(voxel P<0.001,cluster P<0.05).Functional connectivity analysis revealed weakened auditory and right frontal-parietal networks(voxel P<0.001,cluster P<0.05),enhanced visual network(voxel P<0.001,cluster P<0.05),and synergistic auditory network and hypothalamic-pituitary system.Conclusion Significant differences in neural activity and functional connectivity in specific brain regions were observed after acupuncture intervention at uterine acupoints;the hypothalamic-pituitary system also showed various active states in different brain regions.It is speculated that the effective mechanism of acupuncture at uterine acupoints is related to the regulation of reproductive hormones,emotional changes,and somatic sensations.Therefore,the methods used in this study could clarify the neural mechanism of uterine-point acupuncture in the treatment of gynecological diseases and may serve as a reference for other studies pertaining to acupuncture. 展开更多
