Objectives: To define clinical differences in the acute phase response and serum acute phase reactants between gout, pseudogout and crystal-induced arthritis in the presence of non-articular infections (CAI). Patients and Methods: Eleven patients with definite gout, 12 patients with pseudogout and 5 patients with CIA were included in the study. Results: The erythrocyte sedimentation rate (ESR) was significantly different between gout (68.2 ± 49.9 mm/Hr) and CIA (113.8 ± 37.2 mm/Hr) but not between gout and pseudogout (83.9 ± 45.6 mm/Hr) or between pseudogout and CIA. The C-reactive protein (CRP) was significantly increased between gout (10.1 ± 7.9 mg/dL) and pseudogout (18.9 ± 9.8 mg/dL), gout and CIA (36.5 ± 12.4 mg/dL) as well as between pseudogout and CIA. The peripheral white cell count was significantly different between gout (9.27 ± 3.7 k/μL) and CIA (16.5 ± 6.8 k/μL), and between pseudogout (8.9 ± 3.2 k/μL) and CIA. Conclusions: Measurement of ESR and CRP are helpful in crystal-induced arthritis. The CRP has more discriminating utility than the ESR in distinguishing between gout, pseudogout and CIA. Peripheral wbc is most useful for differentiating crystal-induced arthritis from CIA.

阿尔及利亚运输系统由公路、铁路和海运等各种运输方式组成。近年来,由于人口、农业、矿业及工业活动的不断发展,铁路逐渐在沿海港口及主要城市的货物运输中扮演着重要的角色。目前,在铁路运输中还面临着许多问题,如机车分配问题。并且运输公司已经逐渐意识到组织优化方法在提升运输效率方面的重要作用。本论文的研究目标是:寻找并运用合理的数学模型研究铁路货物运输中的机车分配问题,从而在有限的机车资源条件下,使线路的运输能力最大。面对各种运输难题,国家铁路运输公司凭借其丰富的经验,满足了全国大部分的运输需求。随着运输市场的不断发展和扩大,运输方式的多样性及不确定性,促使铁路运输部门采取相应的措施,以使铁路运输效益最大化。为了铁路企业的发展,决策者需要从众多的可选方案中选取最优方案。同时,为了企业的可持续发展,公司需要制定铁路运输的中长期发展规划,从而实现货物运输中各运输设备的优化管理。本文研究铁路运输中的机车分配问题如下:基于各货物的运输需求和各列车的运输线路,在确定的机车资源配置条件下,采取最优的分配方法将各机车分配至铁路列车中,以使铁路线路的运输能力最大化,进而高效地完成货物运输任务。本文构建“多元线性优化”模型,并采用“Branch-Bound”理论和Cplex平台求解该优化模型,以得出最优的机车分配方案。

The venom apparatus in the large carpenter bees, Xylocopafenestrata （Fabricius）（Hymenoptera： Apidae） has been studied It consists of typical parts, i.e., the venom sac, free filament, Dufour gland, sting shaft and accessory sclerites. It is highly sclerotized and concealed by the 7th abdominal tergite and sternite. The venom sac serves as a reservoir for the venom which synthesized by the convoluted gland present in it, which is remarkably uniform to that of ants. The median duct extends from lower portion of venom sac, which measures 2.5 ±0.17 mm （mean ＋ SD）（n = 20） in length. The Dufour gland is a tube-like structure which is inserted in the sting-bulb. The triangular plate is attached at terminal portion of rami, which is in turn attached with lancets. The gonostyli are paired long and tubular structure with 5.29 ± 0.23 mm （n = 20） in length. The sting length is 5.29 ±0.23 mm （n = 20）. The fulcral arm is well-developed with an inverse Y-shaped structure present beneath the sting-bulb. Barbs on the sting shaft are weakly developed in X fenestrata but well developed in ants. The venom apparatus ofX. fenestrata when compared is similar to the bees but differs from that of the wasps and ants.

This paper proposes the use of Group Method of Data Handling (GMDH) technique for modeling Magneto-Rheological (MR) dampers in the context of system identification. GMDH is a multilayer network of quadratic neurons that offers an effective solution to modeling non-linear systems. As such, we propose the use of GMDH to approximate the forward and inverse dynamic behaviors of MR dampers. We also introduce two enhanced GMDH-based solutions. Firstly, a two-tier architecture is proposed whereby an enhanced GMD model is generated by the aid of a feedback scheme. Secondly, stepwise regression is used as a feature selection method prior to GMDH modeling. The proposed enhancements to GMDH are found to offer improved prediction results in terms of reducing the root-mean-squared error by around 40%.

Introduction: Surgical site infections (SSIs) remain the most common health care associated infections in the surgical population. Preoperative surgical preparation solutions containing alcohol are believed to be best at eradicating skin microorganisms. The efficacy of alcohol is concentration dependant, with a concentration of greater than 60% most bactericidal. Surgical antisepsis guidelines do not stipulate how long alcoholic preparation solutions can be left out prior to use. Method: 30 ml of Alcoholic Iodine (Iodine 1% in Alcohol 70% (v/v)) and Alcoholic Chlorhexidine (Chlorhex-idine 2% in Alcohol 70% (v/v)) were left to stand in gallipots in an operating theatre equipped with laminar flow. Sam-ples were taken at 0, 30, 60 and 120 minutes and the alcohol content was analyzed. The experiment was repeated 3 times for each time interval. Results: The Alcoholic Iodine group demonstrated significant decrease in alcohol concen-tration, from a mean of 76% (SD 3.6) to a mean of 37.7% (SD 2.9) in only 30 minutes. This effect was sustained, reaching a mean concentration of 26% (SD 2.9) alcohol at 120 minutes. The Alcoholic Chlorhexidine group did not exhibit the same degree of concentration drop, the concentration dropped marginally to 71.5% (SD 2.7) at 120 minutes from 83.4% (SD 0.4). Conclusion: Alcoholic Iodine exhibits significant evaporation under operating room conditions after 30 minutes. Alcoholic Chlorhexidine does not appear to undergo similar losses in concentration. We recommend that alcoholic surgical preparation solutions must be poured immediately prior to use, and must be discarded if left un-covered for more than a few minutes.

Chlorella vulgaris （CV） has been reported to have antioxidant and anticancer properties. We evaluated the effect of CV on apoptotic regulator protein expression in liver cancer-induced rats. Male Wistar rats （200-250 g） were divided into eight groups： control group （normal diet）, CDE group （choline deficient diet supplemented with ethionine in drinking water to induce hepatocarcinogenesis）, CV groups with three different doses of CV （50, 150, and 300 mg/kg body weight）, and CDE groups treated with different doses of CV （50, 150, and 300 mg/kg body weight）. Rats were sacrificed at various weeks and liver tissues were embedded in paraffin blocks for immunohistochemistry studies. CV, at increasing doses, decreased the expression of anti-apoptotic protein, Bcl-2, but increased the expression of pro-apoptotic protein, caspase 8, in CDE rats, which was correlated with decreased hepatoctyes proliferation and increased apoptosis as determined by bromodeoxy-uridine （BrdU） labeling and terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling （TUNEL） assay, respectively. Our study shows that CV has definite chemopreventive effect by inducing apoptosis via decreasing the expression of Bcl-2 and increasing the expression of caspase 8 in hepatocarcinogenesis-induced rats.

Aim： To investigate the expression of androgen receptors in the extragenital tissues of developing human embryo. Methods： Using immunohistochemistry, we investigated the distribution of androgen receptor （AR） in the extragenital tissues of paraffin-embedded tissue sections of first trimester （8-12 weeks gestation） human embryos. Gender was determined by polymerized chain reaction. Results： There were no differences in the expression and distribution of AR in male and female embryos at any stage of gestation. AR expression was seen in the thymus gland. The bronchial epithelium of the lungs showed intense positive staining with surrounding stroma negative. Furthermore, positive staining for androgen receptor was exhibited in the spinal cord with a few positive cells in the surrounding tissues. Cardiac valves also showed strong positive staining but with faint reactivity of the surrounding cardiac muscle. There was no staining in kidney, adrenal, liver or bowel. Conclusion： This study demonstrates that immunoreactive AR protein is present in a wide variety of human first trimester fetal tissues and shows the potential for androgen affecting tissues, which are mostly not considered to be androgen dependent. Moreover, it implies that androgen might act as atrophic factor and affect the early development of these organs rather than simply sexual differentiation.
