Plant Communities and Factors Responsible for Vegetation Pattern in an Alpine Area of the Northwestern Himalaya

The study intended to describe the alpine vegetation of a protected area of the northwestern Himalaya and identify the important environmental variables responsible for species distribution.We placed random plots covering different habitats and altitude to record species composition and environmental variables.Vegetation was classified using hierarchical cluster analysis and vegetation-environment relationships were evaluated with Canonical Correspondence Analysis.Four communities,each in alpine shrub and meadows were delineated and well justified in the ordination plots.Indicator species for the different communities were identified.Maximum species richness and diversity were found in community IV among shrub communities and community II among the meadows.Studied environmental variables explained 61.5% variation in shrub vegetation and 59.8% variation in meadows.Soil variables explained higher variability (~35%) than spatial variables (~21%) in both shrubs and meadows.Altitude,among the spatial variables and carbon/nitrogen ratio and nitrogen among the soil variables explained maximum variation.About 40% variations left unexplained.Latitude and species diversity among the other variables had significant correlation with ordination axes.Study showed that altitude and C/N ratio played a significant role in species composition.Extensive sampling efforts and inclusion of other non-studied variables are also suggested for better understanding.
The Role of Phytochrome in Stress Tolerance

It is well-documented that phytochromes can control plant growth and development from germination to flowering. Additionally, these photoreceptors have been shown to modulate both biotic and abiotic stress. This has led to a series of studies exploring the molecular and biochemical basis by which phytochromes modulate stresses, such as salinity, drought, high light or herbivory. Evidence for a role of phytrochromes in plant stress tolerance is explored and reviewed.
RNA Editing Sites Exist in Protein-coding Genes in the Chloroplast Genome of Cycas taitungensis

RNA editing is a post-transcriptional process that results in modifications of ribonucleotides at specific locations. In land plants editing can occur in both mitochondria and chloroplasts and most commonly involves C-to-U changes, especially in seed plants. Using prediction and experimental determination, we investigated RNA editing in 40 protein-coding genes from the chloroplast genome of Cycas taitungensis. A total of 85 editing sites were identified in 25 transcripts. Comparison analysis of the published editotypes of these 25 transcripts in eight species showed that RNA editing events gradually disappear during plant evolution. The editing in the first and third codon position disappeared quicker than that in the second codon position. ndh genes have the highest editing frequency while serine and proline codons were more frequently edited than the codons of other amino acids. These results imply that retained RNA editing sites have imbalanced distribution in genes and most of them may function by changing protein structure or interaction. Mitochondrion protein-coding genes have three times the editing sites compared with chloroplast genes of Cycas, most likely due to slower evolution speed.
The influence of hyaluronic acid on vascular endothelial cell proliferation and the relationship with ezrin/merlin expression

It has been established that hyaluronic acid (HA) glycans (nHA) and oligosaccharide (oHA) exert different effects on the biological function of the vascular endothelial cell (EC), resulting in altered regulation of angiogenesis. However, the specific mechanism is still unclear. Our study focused on the effects of nHA and oHA on the ezrin and merlin proteins in EC. The expression of ezrin and merlin was silenced by siRNA, and the regulation on EC growth as well as the mRNA expression and activation (phosphorylation) of ezrin and merlin stimulated by oHA and nHA was investigated. The results revealed that when treated with nHA, there was no significant change in ezrin expression or activation. After being treated with oHA, the expression and activation of ezrin were definitively increased whereas there were no obvious changes in merlin expression (including its phosphorylation). With ezrin expression silenced, the expression of merlin as well as its phosphorylation levels in nHA-stimulated human umbilical vein endothelial cells were notably elevated, while there was no significant change induced by oHA. With merlin expression silenced, no obvious change was found in the expression of ezrin (including its phosphorylation) induced by nHA. Conversely, the expression of ezrin and its activation was significantly improved after being treated with oHA. The results suggest that the mechanism for the promotion of EC proliferation by oHA is likely related to the expression and activation of ezrin, and the inhibition of EC proliferation by nHA is likely related to the expression and activation of merlin.
要重视微小RNA在HCV感染和防治研究中的作用

丙型肝炎病毒（HCV）感染是引起肝硬化、肝癌的主要原因之一，严重危害人类健康，目前尚无有效的疫苗，并且丙型肝炎疗法也存在一定局限性。微小RNA (miRNAs)具有序列特异性调节基因表达的功能，参与调节生物体的生长、发育、病变等多个环节。近期研究发现，miRNAs可调控HCV复制，并与丙型肝炎进程及干扰素应答相关，因此需重视微小RNA在HCV感染和防治中的作用，开发基于miRNAs靶点的治疗新策略，为丙型肝炎的临床诊治开辟新领域。
Delta Excitation Calculation Studies in Compressed Finite Spherical Nucleus ~(40)Ca

With an oscillator basis, the nuclear Hamiltonian is defined in a no-core model space. It consists of an effective nucleon-nucleon interaction obtained with Brueckner theory from the Reid soft core interaction, a Coulomb potential, nucleon-delta transition potentials, and delta-delta interaction terms. By performing spherical Hartree-Fock (SHF) calculations with the realistic baryon Hamiltonian, the ground state properties of ~(40)Ca are studied. For an estimate of how the delta degree of freedom is excited, SHF calculations are performed with a radial constraint to compress the nucleus. The delta degree of freedom is gradually populated as the nucleus is compressed. The number of Δ's is decreased by increasing model space. Large amount of the compressive energy is delivered to create massive A in the nucleus. There is a significant reduction in the static compression modulus for RSC static compressions which is reduced by including the A excitations. The static compression modulus is decreased significantly by enlarging the nucleon model space. The results suggest that inclusion of the delta in the nuclear dynamics could head to a significant softening of the nuclear equation of state.

3ds max软件在解剖学理论教学中的应用

在解剖学学习中，人体一些解剖部位结构细小、复杂，难以暴露清楚，细微结构不易辨认，给教学带来很大不便。如人的眼球，一般的教学图谱图像只能显示平面结构，而用3d max构建人体眼球三维模型可以对眼球解剖模型进行虚拟仿真操作，模拟解剖学的标本观察，虚拟解剖操作等，克服了以往传统解剖学教材和图谱的缺点，可以成为传统教材和解剖学图谱的有力补充。近年来随着计算机三维模拟和立体成像技术的发展，在医学科学领域已出现许多三维重建的方法，一般是采用人体组织器官切片的方法，将标本分多重切片，通过专业扫描仪或相机将切片断面转换为多幅二维图像，然后使用SGI图形工作站或高速计算机处理成三维图像。但这种方法投资巨大，要求自主编写图形处理软件，需要多个领域的专业人员合作完成，难以普及。
Magnetic properties and crystallization kinetics of Zn_0.5Ni_0.5Fe_2O_4

Precursor of nanocrystalline Zn_0.5Ni_0.5Fe_2O_4 was obtained by grinding mixture of ZnSO_4·7H_2O, NiSO_4·6H_2O, FeSO_4·7H_2O, and Na_2CO_3·10H_2O under the condition of surfactant polyethylene glycol (PEG)-400 being present at room temperature, washing the mixture with water to remove soluble inorganic salts and drying it at 373 K. The spinel Zn_0.5Ni_0.5Fe_2O_4 was obtained via calcining precursor above 773 K. The precursor and its calcined products were characterized by differential scanning calorimetry (DSC), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The result showed that Zn_0.5Ni_0.5Fe_2O_4 obtained at 1073 K had a saturation magnetization of 74 A·m2·k~(g?1). Kinetics of the crystallization process of Zn_0.5Ni_0.5Fe_2O_4 was studied using DSC technique, and kinetic parameters were determined by Kissinger equation and Moynihan et al. equation. The value of the activation energy associated with the crystallization process of Zn_0.5Ni_0.5Fe_2O_4 is 220.89 kJ·mol~(?1). The average value of the Avrami exponent, n, is equal to 1.59±0.13, which suggests that crystallization process of Zn_0.5Ni_0.5Fe_2O_4 is the random nucleation and growth of nuclei reaction.
TiO_2-coated SnO_2 hollow spheres as anode materials for lithium ion batteries

TiO_2-coated SnO_2 (TCS) hollow spheres, which are new anode materials for lithium ion (Li-ion) batteries, were prepared and characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), cyclic voltammetry (CV), and galvanostatic charge/discharge tests. The results obtained from XRD, SEM, and TEM show that TiO_2 can be uniformly coated on the surface of SnO_2 hollow spheres with the assistance of anionic surfactant. The cyclic voltammograms indicate that both TiO_2 and SnO_2 exhibit the activity for Li-ion storage. The charge/discharge tests show that the prepared TCS hollow spheres have a higher reversible coulomb efficiency and a better cycling stability than the uncoated SnO_2 hollow spheres.
吉林省人参土壤中重金属污染水平及生物有效性研究

Phosphorous Enrichment in Molten Adjusted Converter Slag: Part II Enrichment Behavior of Phosphorus in CaO-SiO_2-FeO_x-P_2O_5 Molten Slag

The enrichment behavior of phosphorus in CaO-SiO_2-FeO_x-P_2O_5 slag was studied by making an investigation on the distribution of phosphorous content in the CaO-SiO_2-FeO_x-P_2O_5 molten slag. The research results showed that the 2CaO·SiO_2 solid particles existing in molten slag were the condensation sites for the phosphorus enrichment. The enrichment process of phosphorus in the molten slag can be recognized as three substeps: mass transfer of phosphorus from bulk slag to the surface of 2CaO·SiO_2 particle, superficial solid solution reaction of phosphorus around the 2CaO·SiO_2 particle, and diffusion of phosphorus through the product layer of 2CaO·SiO_2-3CaO·P_2O_5 solid solution to the inner of 2CaO·SiO_2 particle. Moreover, higher temperature is favorable to the phosphorous enrichment from molten bulk slag to the 2CaO·SiO_2 particles.

重视妇科恶性肿瘤化疗毒副作用的防治

化疗在妇科恶性肿瘤的治疗中占有重要地位。化疗作为全身性的治疗措施能有效控制肿瘤的生长、扩散和转移，对一些化疗高度敏感的妇科恶性肿瘤，如滋养细胞肿瘤和卵巢恶性生殖细胞肿瘤，化疗可以达到治愈的疗效。随着新型化疗药物的出现和肿瘤治疗理念的更新，化疗已开始从妇科恶性肿瘤辅助性治疗向主导性治疗过渡，化疗与手术、放疗、免疫治疗相结合的综合治疗将是妇科恶性肿瘤治疗的发展趋势。但是，化疗是把“双刃剑”，在杀死肿瘤细胞的同时，也不可避免地会损伤正常细胞，导致化疗毒副作用发生。尽管与手术、放疗相比，化疗所导致的不可逆的严重毒副作用相对较小，但是如果不予重视，不进行正确处理，也会对患者造成严重的身心损害，甚至威胁患者生命，加重患者的经济负担。随着价值医学理念的引入和肿瘤治疗人性化的普及，在妇科恶性肿瘤的治疗中，如何合理使用化疗，充分发挥其治疗作用，减少其严重的毒副作用，是临床亟待解决的问题，越来越受到重视和关注。

Enterovenous fistulization: A rare complication of Crohn's disease

The presence of hepatic portal venous gas (HPVG) is associated with numerous diseases, and has been regarded as a serious, even catastrophic condition. However, anecdotal reports mention that some patients with inflammatory bowel disease (IBD), who developed HPVG after diagnostic examinations of the colon, were successfully managed with antibiotic therapy and have followed benign courses. In contrast, among IBD patients, the development of HPVG is rarely caused by enterovenous fistula. We describe a 32-year-old man with Crohn's ileocolitis who presented with hypotension and fever associated with HPVG, as well as superior mesenteric vein thrombosis, possibly caused by enterovenous fistula, who was successfully managed by surgery. We also review the literature concerning portal venous gas associated with Crohn's disease.
结肠小袋纤毛虫合并梨形鞭毛虫及真菌感染的诊疗体会

结肠小袋纤毛虫是猪体内的常见寄生虫，猪是本病的重要传染源，通常认为人的感染来源于猪，不少病例有与猪接触的病史，因此询问病史要详细，尤其对来自农村的患者，要询问有无饲养家猪和屠宰生活经历。本例患者，结肠小袋纤毛虫、蓝氏贾第鞭毛虫和真菌孢子同时感染，实属罕见。经详问病史，该患者自述以种菜为业，养家猪>10年，经常裸露四肢为蔬菜浇灌粪便，餐饮住宿常在田间茅屋，常食生菜。蓝氏贾第鞭毛虫感染是经口传播，包囊随粪便排出体外，所以只要注意个人卫生即可阻断传染，做到饭前便后洗手，此虫体少见，治疗简单，给予甲硝唑治疗即可治愈，关键是找到病原体，该患者自发病到就诊我院以前，均未做大便涂片检查；患者由于长期服用抗菌药物而导致真菌感染，到我院查出病原体后给予甲硝唑、黄连素、酮康唑治疗1周后痊愈。

冠状动脉回旋支狭窄所致胸前导联ST段压低酷似前降支病变二例

研究表明,在前壁心肌缺血患者，左前降支是罪犯血管，而’下壁缺血，则可能为右冠脉或回旋支病变。本文二例患者的冠脉造影结果提示回旋支为缺血相关血管,而心电图表现为单纯胸前导联ST段压低,其心电图表现与冠脉缺血相关血管不呈对应关系，分析其原因：首先，本文二例患者均为多支冠脉病变,其心肌缺血面积大,缺血冠脉的狭窄部位相互对应，因此产生的缺血型ST-T向量相互中和抵消，从而使这些缺血心肌产生的心电效应处于一个低水平的平衡，当有相关血管缺血时，心电图表现为各个心电向量的综合表现，因此心电图出现了本文所述改变。另外冠脉侧支循环的建立,它可以改善局部心肌缺血，对心脏具有保护作用,但具有冠脉侧支循环的患者，有可能掩盖心电图的缺血表现,应引起重视。
Essence of resistance to anti-angiogenic therapy in tumors

To the Editor: Recently, I read, with great interest, the article Patterns in the occurrence and development of tumors by Lin~1 published in your honored journal. The author of the paper suggests that the mechanism of the occurrence and progress of tumors could involve the self-renewal of the cells and repair of injured tissue. The key players are the responding cells, which, due to a functional defect, mistakenly "interpret" such a process as incomplete, thus resulting in continuous replication. During this process, tumor angiogenesis provides nutrition to those responding cells in tumor tissue.
Helicobacter pylori in middle ear of children with otitis media with effusion

Background Otitis media with effusion (OME) is a common pediatric disease, but its pathogenesis remains uncertain. The relationship between OME and Helicobacter pylori (HP) is currently being studied, and a relationship has not yet been confirmed. The purpose of this study was to show that a relationship does exist between HP and OME. Methods The study consisted of 60 patients who were diagnosed with OME and had ventilation tube insertions with or without an adenoidectomy. This study included an additional 30 patients who had only received an adenoidectomy without being diagnosed with OME. The effusion samples were analyzed with polymerase chain reaction (PCR) and the campylobacter-like organism (CLO) test. The adenoid tissue samples were analyzed with the CLO test. Results Eighteen patients among the 60 patients (30%) tested positive for HP. In the cases with adenoids, 15.6% of the OME patients and 13.3% of the adenoidectomy only patients were positive for HP. There were no differences between the prevalence of HP in the adenoids of OME patients and the patients without OME. Conclusion HP can be considered one of the causes of OME.

手部淋巴管瘤二例

3。治疗及预后：以手术切除为首选方法。淋巴管瘤有浸润性生长和复发率高的特点，常无包膜，与周围组织及表面皮肤无明显界限，因此切除时应根据肿瘤发生的部位及侵及的范围，尽量一次完整彻底切除瘤体，以减少复发的机会。对于淋巴管瘤病变局限，手术易将肿物完全切除，复发几率较低。本组2例患者术中所见肿物均无明显包膜和界限，例1病变局限，术后随访5年未见复发。如果病变广泛、肿物无明显界限，术中很难将肿物完全切除，复发率极高。例2首次手术后1年复发可能与术中肿瘤组织切除不彻底有关。此外淋巴管瘤还可采取硬化疗法，即在瘤体内穿刺抽吸后注射OK-432、博来霉素、10%乳糖酸红霉素、平阳霉素、纤维硬化剂等，能促使瘤壁发生炎性粘连，主要适用于海绵状淋巴管瘤和囊状淋巴管瘤，使淋巴管道发生闭塞而防止复发。

Influence of Ag doping on the microstructure and electrical properties of ZnO-Bi_2O_3-based varistor ceramics

Silver in the form of AgNO_3 was added to ZnO-based varistor ceramics prepared by the solid-state reaction method.The effects of AgNO_3 on both the microstructure and electrical properties of the varistors were studied in detail.The optimum addition amount of AgNO_3 in ZnO-based varistors was also determined.The mechanism for grain growth inhibition by silver doping was also proposed.The results indicate that the varistor threshold voltage increases substantially along with the AgNO_3 content increasing from 0 to 1.5mol%.Also,the introduction of AgNO_3 can depress the mean grain size of ZnO,which is mainly responsible for the threshold voltage.Furthermore,the addition of AgNO_3 results in a slight decrease of donor density and a more severe fall in the density of interface states,which cause a decline in barrier height and an increase in the depletion layer.
