目的研究不同类型沙眼衣原体蛋白在输卵管性不孕中的致病作用，预测具有临床检测价值的沙眼衣原体蛋白抗体。方法本研究共纳入输卵管性不孕组（TFI）58例，正常生育组（FC）41例，非输卵管性不孕组（IFC）18例。血清检测CT-IgG ELISA试剂盒检测三组人群血清中CT-IgG的表达情况；利用前期获得表达、纯化的6种沙眼衣原体蛋白，建立这6种沙眼衣原体蛋白抗体的ELISA检测方法，分别检测6种沙眼衣原体蛋白抗体在TFI组、FC组和IFC组血清中的表达情况；对三组研究对象6种沙眼衣原体蛋白抗体的OD值进行统计描述，以CT-IgG的检测结果（阳/阴）为参考标准，绘制6种沙眼衣原体蛋白抗体的受试者工作特征曲线，利用约登指数确定各抗体的截断值。以TFI作为参考类，将FC、IFC分别与参考类建立两个无序多分类logistic回归模型，探究沙眼衣原体蛋白抗体、年龄预测TFI、FC和IFC的价值，并利用后退法筛选变量。结果各组研究对象CT376和CT443抗体OD值不全相同，CT-IgG阳性率不全相同。经两两比较发现，TFI组的CT376抗体OD值高于FC组（0.86 vs. 0.60，P=0.026）。TFI组的CT376抗体OD值高于IFC组（0.86 vs. 0.64，P=0.026）。IFC组CT443抗体OD值高于TFI组（0.59 vs. 0.34，P=0.036），高于FC组（0.59 vs. 0.30，P=0.02）。经过比较，CT376抗体的阳性率在三组间不全相同（PP P=0.068， OR=0.359，95%CI（0.120，1.078）］。CT-IgG是输卵管性不孕发生的独立危险因素，CT376抗体尚不能成为输卵管性不孕的独立危险因素；TFI与IFC建立的无序多分类logistic回归分析显示，在不孕的患者中，CT-IgG ［PPP

对中、美、欧现行规范关于钢结构截面类型及宽厚比限值的要求进行了归纳比较,利用ABAQUS有限元软件进行了单根H形钢梁考虑初始缺陷的屈曲承载力分析并与规范公式计算结果进行了对比。在此基础之上,以雄安站站房雨棚钢结构为背景,选取具有代表性的区域建立空间交叉H形钢梁精细有限元模型。对不同板件宽厚比的空间交叉H形钢梁进行了非线性屈曲承载力分析,研究了翼缘宽厚比及腹板高厚比对空间交叉H形钢梁局部稳定性和屈曲性能的影响。研究结果表明:ABAQUS模型对钢梁整体稳定性计算结果与规范公式吻合度较高,设计中采用杆件单元模型进行结构整体稳定性分析是安全合理的。考虑翼缘约束作用的H形钢梁腹板屈曲计算模型与该项目交叉钢梁有限元弹性屈曲分析结果吻合良好,结构起坡所引起的不均匀正应力是导致钢梁腹板失稳的主要因素。翼缘厚度确定后,根据上翼缘失稳与腹板局部屈曲临界值确定腹板厚度,依据S3级截面要求所控制的次梁腹板厚度是经济合理的。

为了减小钢框架梁柱弱轴连接中柱腹板上的应力水平,提出了在梁端加过渡竖板的方式以使得柱翼缘更好地参与受力。同时为了使塑性铰不出现在梁柱连接焊缝处,对梁翼缘进行削弱处理,最终提出了一种新型的梁端加强与削弱并用的梁柱弱轴连接(SWWC)形式,并运用有限元软件ABAQUS对已有的RBS型工字形柱弱轴连接节点的试验进行模拟验证后,对此类节点进行循环荷载作用下的受力性能分析。结果表明:在梁端加过渡竖板可以明显降低节点域的Mises应力水平,使得梁截面的屈曲主要集中在竖向板的外侧;在梁端加过渡竖板的同时对梁翼缘进行削弱处理可以使塑性铰外移;随着削弱深度c的增加,节点的承载力逐渐降低,RBS削弱处的屈曲发展得越充分,削弱起始位置至梁端的距离a和削弱区域的长度b对节点的承载力影响会很小,随着参数a或b的增加,梁上塑性铰中心逐渐远离梁翼缘焊缝处;建议削弱参数c=0.17bf,a取值范围为0.65bf～0.70bf,b=0.75hb,其中bf和hb分别为梁翼缘宽度和梁截面高度。

The purpose of this experiment was to investigate the effects of enzymatic hydrolysis of black soldier fly peptide powders instead of fish meal in different proportions on growth performance, serum biochemistry and intestinal health of soft-shelled turtles. Eight ponds of soft-shelled turtles were selected for the experiment and randomly divided into four groups. Each group had two replicates (ponds), and 15 000 softshelled turtles were raised in each pond for a trial period of three months. Four groups were added with 0 (control group), 3%, 6%, and 9% peptide powders groups (enzymatic hydrolysis of black soldier fly peptide powders were used in proportion to replace fish meal). The results showed as follows: compared with the control group, the 3%, 6%, and 9% peptide powders groups significantly increased the weight of 3-month-old soft-shelled turtles and significantly reduced the mortality (P<0.05). Compared with the control group， the 3%, 6%, and 9% peptide powders groups significantly increased blood glucose levels (P<0.05); the triglyceride levels of 6% and 9% peptide powders were significantly decreased (P<0.05); the calcium content in the serum of the 3% peptide powders group was significantly increased (P< 0.05); the urea nitrogen level of the 9% peptide powders group was significantly reduced (P<0.05); there was no significant difference in total protein, glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase and phosphorus among the groups (P>0.05). There was no significant difference in visceral mass weight, liver weight, hepatopancreatic index, viscerosomatic index, gut length ratio and relative intestine length among the groups (P>0.05). The villus height in the intestine of soft-shelled turtles showed a significant gradient increase with the increase of enzymatic hydrolysis of black soldier fly peptide powders in proportion to fish meal level (P<0.05); the crypt depth of the 6% and 9% peptide powders groups was significantly increased compared with the control group (P<0.05); the villus height/crypt depth in the 9% peptide powders group was significantly increased (P<0.05). In conclusion, replacing fish meal with 3%, 6%, and 9% enzymatic hydrolysis of black soldier fly peptide powders in the diet improve the growth performance of 3- month-old soft-shelled turtles, improve intestinal morphology and structure and have no adverse effects on serum biochemistry and health indicators. In addition, the treatment of 9% enzymatic hydrolysis of black soldier fly peptide powders has the best effect for the soft-shelled turtles. [ABSTRACT FROM AUTHOR]

To clarify the degree of coupling and coordination between herbaceous plant community diversity and soil factors after slope vegetation restoration, the understory herbaceous plant communities and soils of 18 typical slope vegetation greening models in Yan’an New District were used as research objects. Five 1 m× 1 m sample plots were set up in each model and the physical and chemical properties of the soil in the sample plots were measured. The gray correlation method was used to construct a vegetation-soil coupling model to evaluate the coupling relationship between herbaceous plant diversity and soil factors after slope vegetation restoration. The results showed that there were 22 species of herbaceous plants, belonging to 12 families, on the slopes of Yan’an New District. Among them,the families Asteraceae and Poaceae were the most abundant, both accounting for 22. 73% of total species number. The degree of feedback of the herbaceous plant community diversity indices to the soil was in the order of Shannon-Wiener＞ Margalef＞ Simpson＞ Pielou indices. The correlation between the herbaceous plant community diversity and soil factors in the study area was moderate or above, of which the correlation coefficient of soil electrical conductivity, which was more closely related to community diversity, was 0. 852. Overall, the performance of the coupling relationship between herbaceous plant diversity and soils after slope vegetation restoration in Yan’an New District was good, and 66. 67% of existing greening models have already crossed the stage of incongruity in this coupling relationship. However, the understory of herbaceous plant communities and soil systems are yet to reach the optimal coordination level. [ABSTRACT FROM AUTHOR]

Monopterus albus is one of the popular aquatic fish in Asia. Manual processing of eel cannot fully meet the large- scale production at present, due to the time-consuming, laborious, and low safety. In view of its slender and slimy body, an eel- cutting machine is required for the consumption of Monopterus albus. In this study, a miniature machine of automatic cutting was designed for the living Monopterus albus with a sticky surface. The machine consisted of conveying, clamping, and cutting parts. The double-clamped wheel to roller was used to capture the eel for transportation during cutting. The switch between laparotomy and back dissection was realized to change the feeding channel. The adaptive mechanism was equipped to meet the requirements of different sizes of eel cutting. Firstly, the geometry and weight parameters of Monopterus albus were measured using a straight ruler and precision electronic balance. The tribological parameters on the surface of Monopterus albus were measured by the inclined plane. The mechanical parameters of Monopterus albus meat were verified by compression test. Secondly, according to the rigid-flexible coupling principle, the rigid-damping model was equivalent to the contact between the Monopterus albus body and the clamping wheel and slide. The rigid-flexible coupling model was established by Abaqus and Adams simulation software. The analysis model was optimized to take the conveying time of the fish body, output speed, clamping force, and whole machine vibration as the test indexes in single-factor tests, such as the spring stiffness, slope Angle of the slide, and the speed of the clamping wheel. The results show that the clamping force first increased and then decreased with the increase of spring stiffness and the vibration amplitude of the whole machine decreased. But there was little influence on conveying time and output speed. The output time of the fish body decreased with the increase of slope angle, while the output speed, clamping force, and vibration of the whole machine increased. There was an increase in the conveying time of the fish body, the output speed, the clamping force, and the vibration of the whole machine, with the increase of the speed of the clamping wheel. The single- and multi-factor analyses were carried out to obtain the optimal working conditions. Specifically, the clamping wheel speed was 600 r/min, the spring stiffness was 1 200 N/m, and the slope angle was 16°. Finally, the processing experiment was performed on the automatic cutting machine for eel. There was consistency in the vibration amplitude range and the relationship between the three directions of the machine measuring points with the theoretical analysis. At the same time, the output speed of the fish body output machine was also measured to better agree with the theoretical analysis. The cutting of the machine under optimal working conditions has fully met the requirements. The correctness of the theoretical analysis was also verified by the test. The rigid-flexible coupling model can provide a strong reference to research and develop the subsequent equipment. [ABSTRACT FROM AUTHOR]

In recent years, functional hydrogel materials have seen remarkable progress and shown great promise in a myriad of domains, including healthcare, energy, and artificial intelligence. In the biomedical sector, hydrogels stand out due to their intrinsic qualities, such as high-water permeability and superior biocompatibility, enabling diverse and significant advancements in tissue engineering, drug delivery, wound care, and biomimetic sensing. This paper introduces a novel narrative technique, presenting hydrogels from an anthropomorphized perspective to discuss their chemical and physical properties through selected exemplary cases. These cases vividly illustrate the real-world applications and potential value of these materials in contemporary medicine, highlighting instances such as bone tissue repair, myocardial and vascular reconstruction, wound dressing creation, and pioneering uses in biomimetic sensors and neuroprosthetic technologies. This approach does more than simply inform the reader of the scientific principles underpinning hydrogels; it reveals the versatility and wonder of their medical applications and underscores the importance of ongoing research and the development of new hydrogel materials in the advancement of medical technologies.
