Genetic Polymorphisms of Nine X-STR Loci in Four Population Groups from Inner Mongolia, China

Nine short tandem repeat (STR) markers on the X chromosome (DXS101, DXS6789, DXS6799, DXS6804, DXS7132, DXS7133, DXS7423, DXS8378, and HPRTB) were analyzed in four population groups (Mongol, Ewenki, Oroqen, and Daur) from Inner Mongolia, China, in order to learn about the genetic diversity, forensic suitability, and possible genetic affinities of the populations. Frequency estimates, Hardy-Weinberg equilibrium, and other parameters of forensic interest were computed. The results revealed that the nine markers have a moderate degree of variability in the population groups. Most heterozygosity values for the nine loci range from 0.480 to 0.891, and there are evident differences of genetic variability among the populations. A UPGMA tree constructed on the basis of the generated data shows very low genetic distance betweent Mongol and Han (Xi'an) populations. Our results based on genetic distance analysis are consistent with the results of earlier studies based on linguistics and the immigration history and origin of these populations. The minisatellite loci on the X chromosome studied here are not only useful in showing significant genetic variation between the populations, but also are suitable for human identity testing among Inner Mongolian populations.

Preliminary study of the retention mechanism of planktonic copepods in the Jiulong Estuary in China

The horizontal and vertical distribution patterns of five planktonic copepods,Calanus sinicus, Acartia pacifica, Tortanus derjugini, Acartiella sinensis and Pseudodiaptomus poplesia, predominant in the Jiulong Estuary, were investigated from May 2003 to April 2004. The results showed that the distribution of these copepods was related to the tidal period but that each species had its own specific pattern. C. sinicus showed no tidal vertical migration behavior and was thought to be a non-resident species in this estuary. Among Acartia pacifica,T. derjugini,Acartiella sinensis, more individuals occurred in the surface than in the bottom waters during flood tide, and the pattern was reversed during ebb tide. The epibenthic copepod P. poplesia usually remained in the bottom waters in the upstream part of the estuary, but it displayed strong tidally-oriented vertical migration in the middle reaches of the estuary.Taking into account the hydrographic characteristics of the Jiulong Estuary,it was hypothesized that the planktonic copepods in this estuary had more or less adopted the mechanism of vertically migrating to the surface waters during flood tide in order to make use of the inflowing tide, and then sinking to the bottom during ebb tide to avoid being carried out of the estuary by net outflow.
Geochemical records of phosphorus in Jiaozhou Bay sediments-Implications for environmental changes in recent hundred years

Phosphorus is a key element and plays an important role in global biogeochemical cycles. The evolution of sedimentary environment is also influenced by phosphorus concentrations and fractions as well as phosphate sorption characteristics of the marine sediments. The geochemical characteristics of phosphorus and their environmental records were presented in Jiaozhou Bay sediments. Profiles of different forms of phosphorus were measured as well as the roles and vertical distributions of phosphorus forms in response to sedimentary environment changes were investigated. The results showed that inorganic phosphorus (IP) was the major fraction of total phosphorus (TP); phosphorus which is bound to calcium, iron and occluded phosphorus, as well as the exchangeable phosphorus were the main forms of IP, especially calcium-phosphorus, including detrital carbonate-bound phosphorus (Det-P) and authigenic apatite-bound phosphorus (ACa-P), are the uppermost constituent of IP in Jiaozhou Bay sediments. Moreover, the lead-210 chronology technology was employed to estimate how much phosphorus was buried ultimately in sediments. And the research showed that the impacts of human activities have increased remarkably in recent years especially between the 1980s and 2000. According to research, the development of Jiaozhou Bay environment in the past hundred years can be divided into three stages: (1) before the 1980s characterized by the relatively low sedimentation rate, weak land-derived phosphorus inputs and low anthropogenic impacts; (2) from the 1980s to around 2000, accelerating in the 1990s, during which high sedimentation rates, high phosphorus abundance and burial fluxes due to the severe human activities impacted on the whole environmental system; (3) after 2000, the period of the improvement of environment, the whole system has been improved including the decreasing sedimentation rates, concentration and the burial fluxes of phosphorus.
Detection and Genetic Characterization of Rabies Virus from Human Patients

Saliva and blood were collected from two patients who had not received post exposure prophylaxis in the cities of Wenzhou and Xinning respectively. Both patients were confirmed as positive for rabies by detection of rabies virus specific nucleoprotein antibodies in the sera by Western Blot. However, rabies virus specific RNA was only identified in the saliva collected from the patient in Wenzhou. Furthermore, the isolate Zhejiang Wz0 (H) was obtained by inoculating one-day-old suckling mice. Both nucleoprotein (N) and glycoprotein (G) genes from the isolate were amplified by RT-PCR and sequenced. Phylogenetic analysis indicated that the isolate belonged to classic rabies virus, and shared a higher homology with the street viruses from dogs in the main endemic areas in China and the street virus from dogs in Indonesia than with other known strains. Further comparison of the deduced amino acid sequences between the isolate and the vaccine strains used in China showed that the virus had a higher level of homology with the vaccine strain CTN than with the other vaccine strains (3aG, PV, PM and ERA). In particular, amino acid residues substitutions located in antigenic site Ⅲ in the G protein, which could react with the neutralizing antibodies, were observed. These results suggested that the virus belonged to the classic rabies virus, and both N and G genes diverged from the current vaccine strains used in China at either the nucleotide or the amino acid level.
血浆置换治疗肾脏疾病

血浆置换(plasma exchange,PE)是血浆治疗中最传统的一种体外循环治疗方法,已广泛应用于神经系统疾病(如重症肌无力、Guillain-Barrè综合征),血液系统疾病[如栓塞性血小板减少性紫癜(TTP)、多发性骨髓瘤(multiple myeloma,MM)及溶血尿毒综合征(HUS)]等.其基本过程是用血浆分离器,分离并弃除血浆,通过补充白蛋白、新鲜血浆等置换液,以达到清除血浆中致病因子的目的.PE可清除自身抗体、免疫复合物、冷球蛋白、多发性骨髓瘤轻链蛋白、内毒素、胆固醇等致病物质,抑制这些致病因子对各种脏器的损害,逆转病理过程.除此之外,PE还能改善网状内皮系统的清除功能[1],促进内源性毒素的清除.本文主要简述PE治疗肾脏疾病的一些新进展.

Group-based user pairing for virtual MIMO in LTE

A user pairing method is proposed to improve the throughput gain of virtual multiple input multiple output (virtual MIMO) in 3G long-term evolution (LTE).The approach taken in this study separated the user pairing into four steps: 1) the users are divided into two groups according to their signal-to-noise ratio (SNR), and different user pairing metrics are proposed for each group; 2) the scheduler chooses a user for transmitting by a given rule; 3) the scheduler searches the pairing candidate for the selected user in each group; 4) the scheduler chooses the final pairing user from the co-group and crossover-group candidates by using a marginal utility function, to balance fairness and efficiency.The method can improve the throughput of users with high SNR, and guarantee fairness for users with low SNR, so it can be used in 3G LTE systems.The article provides both theoretical analysis and simulation results to support the idea.
Design of coordinator to eliminate redundant local retransmission in wireless networks

Owing to limited bandwidth, high bit error rate, and bursty error in the wireless environment, the performance of the transmission control protocol (TCP) degrades greatly in wireless networks.Up to now, many researchers have contributed greatly to the wireless TCP field.However, in most of their works, the wireless TCP module usually works in the TCP layer and has no idea of the actual time of the packet transmission, which is determined by the Scheduler in the media access control (MAC) layer, and this will bring the inaccuracy to the local retransmission timeout and induce the redundant local retransmission.In this article, a coordinator is introduced into the base-station (BS), which can provide efficient cooperation between the TCP module and the scheduler module.On the bais of the performance analysis and simulation results, the proposed method is shown to eliminate redundant local retransmission, increase throughput, and improve TCP-level fairness in wireless networks.Moreover, this scheme is orthogonal to those existing wireless TCP schemes, thus it can give great compatibility to the current networks, and further enhance the performance of TCP under the condition that the performance improvement benefiting from the existing approaches will not be affected.
Distributed power control algorithm based on game theory for wireless sensor networks

Energy saving is the most important issue in research and development for wireless sensor networks.

Space-borne antenna adaptive anti-jamming method based on gradient-genetic algorithm

A novel space-borne antenna adaptive anti-jamming method based on the genetic algorithm (GA), which is combined with gradient-like reproduction operators is presented,to search for the best weight for pattern synthesis in radio frequency (RF).Combined,the GA's the capability of the whole searching is,but not limited by selection of the initial parameter,with the gradient algorithm's advantage of fast searching.The proposed method requires a smaller sized initial population and lower computational complexity.Therefore,it is flexible to implement this method in the real-time systems.By using the proposed algorithm,the designer can efficiently control both main-lobe shaping and side-lobe level.Simulation results based on the spot survey data show that the algorithm proposed is efficient and feasible.
Hepatitis B Virus X Protein Up-regulates TNF-α and IL-1β Secretion of Macrophages

Objective: To provide the experimental basis for further studying the molecular transformation mechanism of Hepatitis B virus (HBV) X protein (HBx) on hepatocellular carcinoma. Methods: Reconstructed plasmid pcDNA3.1(+)-HBx was transfected into THP-1 macrophages. Expression of HBx was assayed in macrophages lysate by Western-blotting, and TNF-α and IL-1β contents were detected respectively by ELISA. All the data were analyzed by SPSS13.0. Results: In THP-1 macrophages, the pcDNA3.1(+)-HBx plasmid expressed HBx with a molecular weight of about 17 KDa demonstrated by Western-blotting. The secreted TNF-α and IL-1β from macrophages were determined by ELISA, the results from analysis of all groups showed as following: control group was different from LPS group and pcDNA3.1(+) group (P＜0.01), and so was pcDNA3.1(+)-HBx group; but there was no obvious difference between pcDNA3.1(+) group and LPS group (P＞0.05), all of which indicated that transient overexpression of HBx enhanced LPS-induced production of TNF-α and IL-1β by macrophages.Conclusion: Transient overexpression of HBx up-regulates LPS-induced TNF-α and IL-1β secretion of macrophages.
Dynamics of Coastal Land Use Patterns of Inner Lingdingyang Bay in the Zhujiang River Estuary

To satisfy the growing of land demand from economic development,a large scale of land reclamation from sea has been carried out in Inner Lingdingyang Bay in the Zhujiang(Pearl)River estuary in recent years.As a result,the tidal flat and the water channels became narrow,the frequency of floods increased,and the environment was un-dermined.Guangzhou Marine Geological Survey(GMGS)conducted an integrated project for marine geo-environ-ment and geo-hazards survey in 2003.With the integration of multi-temporal remote sensing images of 1977,1978,1988,1996,and 2003,GIS spatial analyzing approach and GPS technique,as well as field data and other background data of the region,this research investigated the comprehensive characteristics and the drivers of coastal land use dy-namics and shoreline changes in Inner Lingdingyang Bay.The results reveal that the reclaimed coastal land was mainly for agriculture and aquaculture in early years,but now they are used for construction sites of harbors and in-dustries,especially high-tech industry

As a very important component of a coastal system,tidal flats come to be a focus of the studies on land-ocean interaction in the coastal zone because those areas are subjected to intense human activities and are highly sensitive to the global change.The Quanzhou Bay,located along the middle part of Fujian coast of China,covers about 136.4km2,and the area of coastal wetland in the entire bay from intertidal to subtidal with 6m of water depth accounts for 96% of the total area.Seven short cores were collected and divided in situ with the interval of 5cm on the coastal wetlands of Quanzhou Bay on April 19,2006.The sediment samples were scattered and the grain sizes were measured by using Mastersizer 2000.Human beings' activities on tidal flat have disturbed the vertical distribution of sediments in stratigraphic sequence and accelerated the sedimentation rates.Grain size analysis results show that the grain size diameters increase and sediment becomes worse sorted towards the sea under the strong human disturbance;Spartina alterniflora can play a role of trapping the fine sediment;but near the bank,the sediment becomes coarse and there are two peak values on frequency curve influenced by the sandpile.The trough formed by human activities along the coastline changes the transport path of water and suspended sediment.The sediments are transported through the trough and deposit in it during the flood;the ebb flow is retarded by the flow output through the adjacent trough,and the deposited sediment can not be re-suspended;then,the sedimentation rate increases.In situ observation show that the sedimentation rate is about 8-10cm/yr.
Stability of Spatial Structure of Urban Agglomeration in China Based on Central Place Theory

This paper brings forward the concept of stability of the spatial structure of urban agglomeration(UA)based on Central Place Theory by introducing centrality index and fractal theory.Before assessment,K=4 is selected as parameter to calculate centrality index and fractal dimension(K represents the quantitive relationship between city and the counties in Central Place Theory),and then found the number of nodes,the type of spatial structure,the spatial al-location of nodes with different hierarchy affecting the stability of spatial structure.According to spatial contact direction and the level of stability,UAs in China are classified into five types.Finally,it is posed as a further question that how to use hierarchical relation K=6 and K=7 in central place system to coordinate with the assessment of stability of spatial structure is brought forward.

《内经》补泻手法中相关要素的研究

《内经》是针灸理论的源头，针刺手法的真正形成始见于《内经》，在《灵枢》《素问》约30万字的医理中有将近一半的篇幅记载着与针灸相关的内容，从针灸工具、针刺原理到针刺深浅、补泻、禁忌等等，这些详尽而完备的论述形成了后代各家针刺手法的理论基础。所以。对《内经》补泻手法中相关要素的深入研究。对于全面、整体上把握针刺手法的内涵十分关键。同时对于针灸临床疗效的提高有现实的指导意义。现就《内经》补泻手法中相关要素分述如下.
梗阻性黄疸病理生理学改变

梗阻性黄疸（obstructive jaundice，OJ）是临床较常见病理状态，主要由于肝外或肝内胆管部分性或完全性阻塞所引起。梗阻性黄疸病人术后并发症和病死率较高，常死于感染和败血症。胆管梗阻后，由于胆汁及其诸多成分不能流入肠内（尤其是完全性梗阻者），将导致胆管内压升高、肝血流改变以及一系列包括体内生物化学、免疫功能及其他脏器功能的变化。本文就其病理生理学改变作一综述。
