AlLi相对Mg−Li合金热压缩变形行为和动态再结晶的影响

采用等温热压缩实验研究含有AlLi相的Mg−5Li−3Al−2Zn(LAZ532)合金的热变形行为;变形温度和应变速率范围分别为473~623 K和0.001~1 s^(−1)。LAZ532合金热变形过程中AlLi相能够阻碍位错运动,从而显著提高合金的峰值应力值。为精确预测LAZ532合金的热变形行为,构建相应的应变补偿Arrhenius本构模型,预测结果与实验结果吻合良好。基于Murty准则,建立相应的热加工图,合理的加工区域在538~623 K和0.001~0.01 s^(−1)范围内。在高应变速率变形条件下,AlLi相不利于LAZ532合金在热压缩过程中的流动稳定性和动态再结晶。此外,变形温度会改变LAZ532合金的动态再结晶形核机制。

IMPROVING THE MECHANICAL PROPERTIES OF COPPER ALLOYS BY THERMO-MECHANICAL PROCESSING

Systematic physical simulation of thermo-mechanical processing routes has been ap-plied on a Gleeble 1500 simulator to four copper alloys (mass %) Cu-0.57Co-0.32Si,Cu-0.55Cr-0.065P, Cu-0.22Zr-0.035Si and Cu-1.01Ni-0.43Si aimed at clarifying theinfluences of processing conditions on their final properties, strength and electricalconductivity. Flow curves were determined over wide temperature and strain rateranges. Hardness was used as a measure of the strength level achieved. High hard-ness was obtained as using equal amounts (strains 0.5) of cold deformation beforeand after the precipitation annealing stage. The maximum values achieved for theCu-Co-Si, Cu-Cr-P, Cu-Zr-Si and Cu-Ni-Si alloys were 190, 165, 178 and 193 HV5,respectively. A thermo-mechanical schedule involving the hot deformation-ageing-colddeformation stages showed even better results for the Cu-Zr-Si alloy. Consequently,the processing routes were designed based on simulation test results and wires of 5 and2mm in diameters have been successfully processed in the industrial scale.

Al-2.56Li-1.29Cu合金拉伸断裂行为的扫描电镜观察

在备有拉伸装置的扫描电镜下,观察了 Al—2.56 Li—1.29Cu 合金拉伸变形及断裂过程。观察结果表明,在固溶淬火及190℃时效状态下,主要析出相为δ’相。随着时效时间的延长,拉伸断口逐渐由韧窝穿晶型向沿晶突脊型及沿晶韧窝型过渡。在固溶状态下,当拉伸应力超过届服强度以后,出现平直滑移带及交叉滑移带;拉伸裂纹在晶内滑移带及晶界处萌生,并主要沿滑移带扩展。欠时效状态下,δ’相的析出量增多,使共面滑移加剧,交叉滑移带难于形成;裂纹除沿晶界扩展外,也有少部分沿滑移带扩展。在达到峰时效以后,交叉滑移带消失;裂纹在三角晶界处萌生并沿晶界扩展。

非青光眼人群中血压和视盘结构关系的Thessa-loniki眼科研究

Purpose:To study the association of blood pressure(BP)status on the optic disk structure as measured with the Heidelberg Retina Tomograph(HRT)in people without glaucoma.Design:Cross-sectional population-based setting study.Methods:Consecutive participants in the Thessaloniki Eye Study were included in this study.HRT images of the optic disk and BP measurements were taken.Hypertension was defined as a systolic BP(SBP)≥ 140 mmHg,diastolic BP(DBP)≥ 90 mmHg,or both.Subjects were classified in three groups by SBP and DBP.The Kruskal-Wallis test was used to compare the three groups with respect to the HRT parameters.Regression models adjusted for age,gender,height,disk size,intraocular pressure,cardiovascular disease,diabetes,and duration of antihypertensive treatment were used for each HRT parameter to compare values among the different groups.The P value was considered significant at<.05.Results:A total of 232 subjects were included in the analysis.Rim area was signifi cantly different among groups when DBP was considered as the criterion to classify subjects(P=.005).In regression models,cup area,and cup-to-disk(c/d)ratio were increased in subjects with normal DBP that was the result of treatment,as compared with both the high DBP and untreated normal DBP groups.Conclusions:In patients without glaucoma,the DBP< 90 mm Hg that results from antihypertensive treatment is associated with increased cupping and decreased rim area of the optic disk.This information should be considered in research aiming to define the role of the BP status as an independent factor initiating optic disk changes and/or as a contributing factor to glaucoma damage.

Assessing the relative perspective of the regulation of kinesiologists among other health professionals

Formerly a self-governed profession, in the Province of Ontario, Canada, kinesiology was designated a regulated profession under the Regulated Health Professions Act (1991). The purpose of this study was to evaluate the perceptions of current health delivery agents to the regulation of kinesiology. An 18-item survey was used to collect data, and a SWOT (strengths, weaknesses, opportunities and threats) framework was used for analysis. The data indicated that kinesiology provides a unique expertise adding to client and patient care and is a needed partner within the multidisciplinary health environment. Similarly, despite the need for the profession to clearly define, delineate, and promote its scope of practice to professionals and to the public, there are increased opportunities that exist within the health care sector, particularly in chronic disease prevention. The addition of kinesiology as a regulated health profession was not considered to be a threat by existing key stakeholders.

Reducing Paediatric Outpatient Waitlists—A Proposed Allied Health Multidisciplinary Approach

Extremely long Australian paediatric outpatient waiting lists have resulted in large numbers of children waiting to see a paediatrician. Analyses of the patient referrals suggest that a large proportion of children may benefit from allied health input, in addition to being seen by the paediatrician. This paper provides an organisational strategy that involves streamlining Allied Health clinical services in an effort to assist with bringing down a Paediatric Out-patient waitlist. The paper describes principles to guide the formation of a Paediatric Allied Health Multi-Disciplinary team that proposes assessment and brief interventions. The service would focus on supporting the paediatricians through the use of structured procedures, telephone intakes, multidisciplinary triage, shared and standardised assessments, collaborative formulations and reports, brief interventions, clinical-community linkages, and allied health student support. A variety of additional important organisational principles are proposed to facilitate patient flow from the perspective of streamlining administrative processes, having adequate administrative support, shared responsibilities, teamwork, flexibility, carrying out intake assessments, determining which referrals were appropriate for allied health, and working closely with medical staff.

Adult patients with allied disorders of Hirschsprung’s disease in emergency department:An 11-year retrospective study

BACKGROUND In the past years,only a few studies with a limited number of adult patients analyzed clinical features of allied disorders of Hirschsprung’s disease(ADHD),most of which were individual case reports or lacked detailed clinical information.Although many studies have reported patients presenting to the emergency department(ED)with recurrent abdominal symptoms for a number of disorders,there are few data involving ADHD.However,owing to a lack of awareness of the disease,misdiagnoses and mistreatments are common.Severe complications such as perforation,bleeding,malabsorption,and even death in ADHD had been reported by many studies.AIM To assist ED clinicians in having a more comprehensive understanding of this disease and making an early suspected diagnosis of ADHD more effectively.METHODS We enrolled 53 patients who visited the ED and were eventually diagnosed with ADHD over the past 11 years in our hospital.Their basic information,clinical manifestations,and imaging findings were analyzed.Blood indices were compared between the ADHD and irritable bowel syndrome(IBS)groups.RESULTS Adult patients with ADHD had a mean age of 48.8±14.3 years,and 77.4%had been treated before admission.The transverse colon was the most common dilated part(73.6%),and constipation(67.9%)was the most common symptom.ADHD patients can present with uncommon symptoms and false-negative imaging findings.Logistic regression analysis indicated that body mass index(BMI)[odds ratio(OR)=0.786,P=0.013],cholinesterase(per 1000 units;OR=0.693,P=0.008),and blood chlorine(OR=0.816,P=0.022)were determined to be independent related factors between the ADHD and IBS groups.The area under the receiver operating characteristics curve of these three indices combined was 0.812(P<0.001).CONCLUSION Emergency physicians should be vigilant regarding patients with chronic constipation,abdominal pain,or abdominal distension,and consider the possibility of ADHD despite its rarity.Abdominal computed tomography examination is recommended as a useful tool in the suspected diagnosis of ADHD.BMI,cholinesterase,and blood chlorine have good discriminative abilities between ADHD and IBS.The nutritional status of adult patients with ADHD is worthy of further attention.Surgical treatment for adult patients with ADHD is important and inevitable.

Three Pillars in the Biden Administration’s China Strategy:Allies,Values,and High-Tech

The Biden Administration has inherited its predecessor’s strategic perception about the growing competition among great powers.As a result,its policy toward China has been largely an extension of its predecessor’s,retaining the elements of competition and revising the instruments to outcompete China.The Biden Administration’s China policy has revolved around three pillars-allies,values,and high-tech,which it believes are America’s strengths in its relations with China.Since Biden took office,the United States has spent most of its diplomatic resources consolidating and building smaller security,economic,and tech alliances with membership restricted to democratic allies only,in an attempt to delink from China and consolidate its hegemonic status in the world.This policy carries the pernicious effect of plunging the world into Cold War-like confrontations.

The Boundary Between Gondwana and Pacifica and the Suturing Ages of Their Allied Terranes in Southwestern China

Two terranes formed since the Late Palaeozoic can be distinguished in southwestern China. One is charac-terized by the Permo-Carboniferous ice-rafted marine gravel-bearing clastic formation and the cold-water faunaof the Gondwana facies, including the Gangmar Co, Lhasa, Sa' gya, Tengchong and Baoshan terranes and theother is marked by the Upper Palaeozoic of the Yangtze type with the Cathaysian flora and the Pacific-typefusulinids, comprising the Changning-Menglian, Shuangjiang-Lancang, Qamdo and Bayan Har terranes. TheLongmu Co-Shuanghu-Dengqen-North Lancang River-Kejie-Mengding suture zone between the two groups ofterranes is the boundary between Gondwana and Pacifica in southwestern China. On the grounds of thesedimentary formation and successive southwestward migration of the Asian nonmarine Jurassic-Cretaceousendemic bivalves, the ages of the suture and some terranes to the southwest of the suture zone are discussed.The Baoshan terrane and the Nyainrong-Sog terrane in the Lhasa composite terrane were firstly pieced togeth-er with the Asian continent in the early Early Jurassic. The northern Tibet-western Yunnan microplate, in-cluding the Gangmar Co, Lhasa and Tengchong terranes, collided with the Asian continent at the end of theEarly Cretaceous Neocomian.

最小子宫内膜异位症患者腹水中细胞因子及sICAM-1:寻找不孕和(或)子宫内膜异位症的识别因子

Objective: To evaluate cytokine levels (IL-1β,TNF-α,IL-6, IL-8), soluble intercellular adhesion molecule-1 (sICAM-1)-and number of macrophages in peritoneal fluid (PF)of women with no minimal endometriosis and associated (or not) infertility in order to discriminate between infertility and/or endometriosis. Study design: Cytokines and sICAM-1 were measured by using quantitative enzyme-linked immunosorbent assay (ELISA) while the macrophages were identified by May-Grunwald-Giemsa and non-specific esterase staining and presented as medians. The measurements were performed in 78 women belonging to four selected subgroups according to their endometriosis and/or infertility status. Statistical analysis was performed using Kruskal-Wallis non-parametric ANOVA test. Additionally, discriminant function analyses were performed. Results: We have found the most elevated macrophage numbers in the groups of women with endometriosis. IL-1βdid not present any statistically significant values differentiating the analysed subgroups. IL-6 (110.0 pg/ml) and TNF-αexhibited the highest concentrations (statistically significant) in a group of fertile women with endometriosis. IL-8 clearly differentiated between the subgroups with infertility and sICAM-1 was statistically significantly elevated in the subgroups of infertile women. In the forward discriminant analysis, when subdividing the studied population according to its infertility status (we considered macrophages, IL-8 and IL-6 in order of probability values), we have found striking probability value of 92%for the correct classification into an infertile population. Conclusion: Out of the range of the analysed factors we have found only the sICAM-1 to be singled out between the standard discriminant analysis and the forward one. However, this important flagging molecule might be of considerable value for discrimination between different types of pathology at the level of immune effector function. The increased levels of TNF-αand IL-6 signified a group of fertile women with endometriosis; however only IL-6 presented a discriminating value in multifunctional analysis of examined subgroups. The analysed range of factors had a greater tendency to discriminate between infertility status rather than endometriosis.

应用碘伏、氧氟沙星及洗必泰减少门诊患者环境中的结膜菌群

Purpose: To compare the reduction of conjunctival bacterial flora by povidone -iodine 4%,ofloxacin 0.3%, and chlorhexidine 0.05%for endophthalmitis prophy laxis before corneal suture removal in an outpatient setting. Methods: In each g roup of 25 consecutive subjects who presented for outpatient ophthalmic evaluati on, one eye was treated with either povidone-iodine4%(PI), ofloxacin 0.3%(Ofl ox) or chlorhexidine 0.05%(Chex). The other eye served as a control. Three minu tes after treatment, cultures were taken from the inferior conjunctival sac in b oth eyes. Following incubation at 35°for 48 hours, the numbers of colonies were counted and compared. The difference in the numbers of colonies in each pair of treated and control eyeswas assessed for each drug and compared. Results: The r eduction in colony-formingunits was highly significant for each of the three dr ugs tested (Wilcoxon signed-ranks test; p < 0.0001). There was no significant d ifference between percent reduction by the three drugs (Kruskal-Wallis test; p= 0.68). Sterile cultures following preparation by PI, Oflox and Chex were obtaine d in 52%, 68%and 52%, respectively. Conclusions: The regimens tested were sim ilarly effective in reducing conjunctival commensals. They may all be considered as options for a quick prophylaxis against infection following suture removal i n an outpatient setting.

激素、雌激素和替勃龙治疗对绝经后阴道上皮凋亡及cyclinD1表达的影响

Objective: To investigate the effects of hormone therapy, estrogen therapy and tibolone on markers of apoptosis including bcl-2, and bax and cyclin D 1 expression in postmenopausal vaginal epithelium. Study design: Thirty postmenopausal women were randomized to the treatment protocols (0.625 mg conjugated equine estrogen (CEE) ? 2.5 mg medroxyprogesterone acetate (MPA); 2 mg estradiol valerate; 2.5 mg tibolone). After baseline vaginal biopsy, control biopsies were performed after 70 days following the initiation of the therapy. Bcl-2, bax, Bcl-2/bax ratio, cyclin D1 measurements were performed immunohistochemically. Data were analyzed by Kruskal-Wallis, Mann-Whitney U and Wilcoxon tests. Results: After the treatment period the above-mentioned parameters were not different among the groups except for cyclin D1 levels. Cyclin D1 expression was found to be strong in patients with treated estradiol valerate. Conclusions: The effects of estrogen on cyclin D1 expression were not detected with tibolone or with the addition of progesterone to estrogen in the vaginal epithelium. Cyclin D1 appeared to have stronger effects on the estrogen related proliferation compared to apoptotic markers in vaginal epithelial cells.
