Reactive nodular fibrous pseudotumor(RNFP), which presents abdominal clinical manifestations and malignant radiographic results, usually requires radical resection as the treatment. However, RNFP has been recently described as an extremely rare benign postinflammatory lesion of a reactive nature, which typically arises from the sub-serosal layer of the digestive tract or within the surrounding mesentery in association with local injury or inflammation. In addition, a postoperative diagnosis is necessary to differentiate it from the other reactive processes of the abdomen. Furthermore, RNFP shows a good prognosis without signs of recurrence or metastasis. A 16-year-old girl presented with a 3-mo history of epigastric discomfort, and auxiliary examinations suggested a malignant tumor originating from the stomach; postoperative pathology confirmed RNFP, and after a 2-year follow-up period, the patient did not display any signs of recurrence. This case highlights the importance of preoperative pathology for surgeons who may encounter similar cases.

An inverse design method of transonic airfoil and wing is described, in which the followingmodifications are made for improving convergence and increasing application ability:an artificial viscosity term is added to the integral equation method to increase the abilityof dealing with the shock; a Riegels type of leading edge correction is taken to removethe singularity at the leading edge of the round-nosed airfoil; a smoothing-relaxation procedureis proposed; all coefficients in the equations are integrated in the analytical form. Aregularity condition in closed form for the transonic airfoils is presented. A few design resultsindicate that this method is effective in the transonic airfoil and wing design.

[Objective] The aim of this study was to develop an indirect sandwich EUSA method for detection of swine vesicular disease virus （SVDV）. [Method] High titer serum against SVDV was prepared respectively by inoculated rabbits and guinea pigs with purified virus. To develop an indirect sandwich EliSA, the optimum concentrations of capture antibody, detection antibody, enzyme conjugate and standard antigen were determined using block titration, and positive threshold value was also determined. The specificity, sensitivity and repeatability of the developed IEliSA were evaluated using cross-reaction test, comparison test and intra-assay repeated test. In addition, standard samples and clinical samples were detected by this method. [ Result] The best working conditions of the developed EliSA are as follows： capture antibody, 1：400; detection antibody, 1 ： 200; enzyme conjugate, 1 ： 8 000; and standard antigen, 1 ： 4. The positive threshold value was found to be 0.20. For the detection by the developed EUSA, no cross-reaction with foot and mouth disease was observed. The developed EliSA had close sensitivity with EliSA recommended by the World Organisation for Animal Health （OIE） but had sensitivity 2 -4 times higher than that of reverse indirect hernagglutination test. In addition, the developed method also had good reproducibility, and the detection results of standard samples were in line withtheir own background. All the 36 clinical samples were negative in the developed EliSA. [ Conclusion] The developed indirect sandwich EliSA can be used for diagnosis of swine vesicular disease.

Dear Editor,Industrial Internet of things(IIoT) is a typical application of cyberphysical system(CPS). In the IIoT, wireless communication is an inevitable trend to replace the deployment-limited wired transmission for cases with large-scale and mobile devices. However, wireless communication gives rise to critical issues related to physical security, such as malicious detections and attacks [1].

[目的]分析闽楠天然次生林自然更新与环境因子之间的关系,为其科学经营及保护提供参考依据。[方法]以江西省吉安市闽楠天然次生林为研究对象,通过标准地调查获取数据,运用多元数量化模型I建立闽楠幼树幼苗重要值与环境因子的关系模型,采用单因素方差分析单个环境因子对闽楠幼树幼苗更新的影响。[结果]研究表明:密度(闽楠下种母树株数、郁闭度、株数密度)、坡位、腐殖质层厚度、坡向、林下植被盖度、凋落物层厚度是影响闽楠天然次生林自然更新的主要因素,偏相关系数在0.325 7 0.715 7之间,t检验结果为极显著或显著;模型复相关系数为0.966,F检验结果为极显著(F=30.96^(**))。[结论]闽楠下种母树株数对其幼树幼苗的更新起着最主要的作用,而郁闭度与株数密度过高或过低、凋落物层越厚、腐殖质层越薄、林下植被盖度越大均不利于其自然更新,同时,半阴坡、下坡位条件下的闽楠幼树幼苗的更新好于其它坡向与坡位。为促进闽楠幼树幼苗的自然更新,林分中闽楠下种母树应保留200株·hm^(-2)以上,以及对郁闭度、林下植被盖度及凋落物层厚度等实施相应的调控措施。
