外科整形手术围手术期潜在出血倾向的判断和处理

术中出血的影响有几个方面:影响术者的视野、操作,延长手术时间,术后肿胀修复时间延长,除给患者生活、工作带来不便,还会增加患者的心理负担,如出血过多可发生失血性休克将对病人身体造成不良影响。为了预防术中的出血给术者和患者带来的影响,准确判断处理围手术期出凝血系统的情况,减少该期潜在性的出血,是保证整形外科手术成功的重要环节。

躯体感觉诱发电位的解剖生理及临床简介

脑诱发电位是相对脑自发电位(EEG)而言。诱发电位是指对神经系统某一特定部位(包括感受器),给予适宜刺激,在该传导系统(包括中枢和周围)的相应部位,可检出的与刺激有锁时关系的电反应。因此,各种诱发电位有其时间和空间的特征。因此。

E.stiedai阿拉尔株部分生物学特性的研究

为了研究斯氏艾美尔球虫（E．stiedai）阿拉尔株的生物学特性，试验以30～35日龄健康兔为研究对象，经口感染8．0×104个／只孢子化纯种E．stiedai卵囊，从感染后第10天开始，每天收集粪便进行卵囊计数，计算其最小潜在期和每克粪便的虫卵数（EPG），并采用常规方法测定卵囊最短孢子化时间和卵囊大小。结果表明：在染虫后第13天才从粪便中检出卵囊，之后卵囊排出量逐渐增多，至感染后第24天达到峰值，而后逐渐减少，至第40天几乎检不出；该虫株最短孢子化时间为33h，卵囊大小为36．4（31．3～38．7）μm×22．8（19．1～27．8）μm，卵囊指数为1．59。

论足球技术训练

足球是高技术项目。搞足球首要在于提高技术。技术成长如逆水行舟,不进则退。足球技术有"消能"、"藏势"、"跑位和奔跑"等等,不能只着眼于"大脚踢球"。足球技术是"非形示性"的,递阶教学作用有限,主要靠"内生性技术发展路线",从"比赛性"实践中训练出来。"内生性"机制在幼儿阶段特别突出;年龄大以后,该机制会消减、退步。高技术靠"深加工",需要"岁月积累"。"岁月积累"在大龄方向上有极限;在溯幼方向上、历史上留有被闲置的"大片沃土"。无论从"内生性"、还是从"深加工"来看,低龄期训练的合理开发,是搞足球的第一个环节、前提性基础、世界水平竞争的关键性起点。

Benefits of combination of electroencephalography, short latency somatosensory evoked potentials, and transcranial Doppler techniques for confirming brain death

Objective: Optimization of combining electroencephalography (EEG), short latency somatosensory evoked potentials (SLSEP) and transcranial Doppler (TCD) techniques to diagnose brain death. Methods: One hundred and eleven patients (69 males, 42 females) from the major hospitals of Zhejiang Province were examined with portable EEG, SLSEP and TCD devices. Re-examinations occurred ≤12 h later. Results: The first examination revealed that the combination of SLSEP and EEG led to more sensitive diagnoses than the combination of SLSEP and TCD. Re-examination confirmed this and also revealed that the combination of TCD and EEG was the most sensitive. Conclusion: The results show that using multiple techniques to diagnose brain death is superior to using single method, and that the combination of SLSEP and EEG is better than other combinations.

Toxicity of novel anti-hepatitis drug bicyclol: A preclinical study

AIM: To study the toxicity of bicyclol to animals. METHODS: Acute toxicity test was performed in Kunming strain mice that were orally given bicyclol at the doses of 3 and 5 g/kg body weight, respectively. Wistar rats were orally administered bicyclol at a dose of 5 g/kg body weight. Death and clinical symptoms of animals were recorded within 7 d. Sub-acute toxicity test was carried out in rats that were treated with various doses of bicyclol (150, 300, 600 mg/kg) once daily for 14 d. Animal behaviors, blood biochemical markers, blood and urine pictures were examined. Chronic toxicity test was conducted in 80 Wistar rats of both sexes. The animals were orally administered with various doses of bicyclol [150, 300, 600 mg/kg, 100-400 folds corresponding to the proposed therapeutic dose (1.5 mg/(kg·d)) of bicyclol for patients] once daily for 6 mo except for Sunday. The control group was given the same volume of 0.2% sodium carboxyl methylcellulose (Na-CMC). Twenty-one beagle dogs received bicyclol (25, 75, 225 mg/kg, 16.6, 50, 150 folds corresponding to the proposed therapeutic dose of bicyclol for patients) once a day for 6 mo except for Sunday. The body weight, food intake, urine and feces, blood picture, blood biochemical markers, and pathological examination of main organs were determined. Mutagenicity and teratogenicity were determined. Mutagenicity assay included Ames's test, chromosome aberration test in CHL cells and micronucleus test in mice. For the teratogenicity assay, pregnant Wistar rats weighing 200-250 g were treated with 0.2,1.0 g/kg bicyclol once daily from the 7th d of gestation for 10 d. RESULTS: The oral LD50 of bicyclol was over 5 g/kg in mice and rats. No noticeable alterations in subacute and chronic toxicity of rats and dogs were demonstrated. No mutagenicity and teratogenicity of bicyclol were found. CONCLUSION: Bicyclol has no detectable chronic toxicity as well as mutagenicity and teratogenicity in animals.

Successful isolation of Helicobacter pylori after prolonged incubation from a patient with failed eradication therapy

Helicobacter pylori(H pylori),a gastric pathogen,is a major cause of chronic gastritis and peptic ulcer disease,and is an important risk factor for the development of gastric malignancies.Culture of the bacterium from gastric biopsy is essential for the determination of drug resistance of H pylori.However,the isolation rates of H pylori from infected individuals vary from 23.5%to 97% due to a number of factors such as biopsy preparation,cultural environment,medium and the method adopted.In the present case,we found that a prolonged incubation period of up to 19 d allowed successful isolation of H pylori from a patient who received triple therapy that failed to eradicate the bacterium.

Environmental impact assessment of China’s primary aluminum based on life cycle assessment

Assessing and accounting for material consumption and environmental impact are necessary to measure environmental externalities of the aluminum industry and to construct an ecological civilization.In this research,life cycle assessment(LCA)theory was used to assess the environmental impact of primary aluminum based on the lime soda Bayer process and different power generation modes,and the sources and distributions of the four selected impact categories were analyzed.The results show that,(1)Negative environmental impact of aluminum industry generally occurs from alumina extraction,carbon anode fabrication and electrolysis,particularly electrolysis and alumina extraction.Primary energy demand(PED),water use(WU),global warming potential(GWP)and freshwater eutrophication potential(FEP)are main environmental impact categories.(2)The environmental load with thermal power is higher than that with hydropower,e.g.,for the former,the greenhouse gas emission coefficient of 21800 kg CO2 eq/t(Al)will be generated,while for the latter,4910 kg CO2 eq/t(Al)will be generated.(3)Both power mode methods reflect the energy structure,whereas direct emissions reflect the technical level,indicating the potential for large energy savings and emission reductions,and some policies,related to clean power,energy efficiency and technological progress,should be made for emission reduction.

Natural products against HIV latency

Antiretroviral therapy has achieved great success in suppressing human immunodeficiency virus(HIV)replication and transforming HIV infection from a fatal disease to a manageable chronic disease.However,the latent HIV reservoir persists in the body of HIVinfected individuals and is prone to reactivation.Therefore,the development of new treatment methods aimed at a complete cure for HIV is needed.The leading strategy for HIV eradication is based on eliminating and preventing the reactivation of latent reservoirs through an approach known as“shock and kill.”This strategy involves the use of latency-reversing agents(LRAs)to activate the HIV provirus in latent viral reservoir cells.Many LRAs can be obtained from natural resources,including plants and marine organisms.In this review,we provide an overview of natural products used to eliminate HIV latency.

Low latency systolic multipliers for finite field GF（2m） based on irreducible polynomials

Systolic implementation of multiplication over GF(2m) is usually very efficient in area-time complexity,but its latency is usually very large.Thus,two low latency systolic multipliers over GF(2m) based on general irreducible polynomials and irreducible pentanomials are presented.First,a signal flow graph(SFG) is used to represent the algorithm for multiplication over GF(2m).Then,the two low latency systolic structures for multiplications over GF(2m) based on general irreducible polynomials and pentanomials are presented from the SFG by suitable cut-set retiming,respectively.Analysis indicates that the proposed two low latency designs involve at least one-third less area-delay product when compared with the existing designs,To the authors' knowledge,the time-complexity of the structures is the lowest found in literature for systolic GF(2m) multipliers based on general irreducible polynomials and pentanomials.The proposed low latency designs are regular and modular,and therefore they are suitable for many time critical applications.

Analysis on Epidemiology Causality Relationship Theory under Food and Drug Safety Context

Violation of food and drug safety and other hazard crimes have the features of long latency and multiple factors. Traditional criminal law causality theory is no controversy to determine causality of criminal responsibility, thus it is necessary to introduce the epidemiology causality theory-it is a kind of causality theory based on epidemic diseases, and it is the high degree of probability in the determination of causality in criminal laws so as to solve the traditional attribution problem, but the theory also exists applicable restriction conditions in judicial practice.

EFFECTS OF SLEEP DEPRIVATION ON WHOLE NIGHT POLYSOMNOGRAPHY IN HEALTHY YOUNG MEN

Objective To assess the effects of sleep deprivation (SD) on the whole night polysomnography (PSG) in healthy young men. Methods The whole night PSG was recorded by using Neurofax-1518K (Nihon Kohden, Japan) system before and after 38 h of SD among 15 healthy male subjects. Results Compared with PSG before SD, post-SD PSG showed significantly shortened sleep latency (before SD: 19.7±9.3, after SD: 5.6±7.3, P<0.05), decreased stage 1 (S1) non-rapid eye movement (NREM) sleep [before SD: (9.2±1.9)%, after SD: (4.0±1.4)%, P<0.05], and increased stage 4 (S4) NREM sleep [before SD: (10.3±3.7)%, after SD: (26.2±4.3)%, P<0.01]. Conclusion During post-SD sleep, the proportion of S4 NREM sleep was increased as compensation in healthy male. In addition, SD was proved to affect electrophysiological brain activities in normal people.
