Abstract： Background With the rapid development of economy and the change of fertility concept in modern population，coupled with the full liberalization of the “two-child” and “three-child” policies，the number of advanced maternal age is increasing year by year. Compared with appropriate maternal age，advanced maternal age is more likely to suffer from depressive symptoms due to personal，family，work，and other reasons. Objective To systematically evaluate the detection rate of postpartum depression in advanced maternal age（≥ 35 years at delivery） in China to provide relevant evidence for early prevention and intervention. Methods CNKI，Wanfang，VIP，CBM，PubMed，Cochrane Library，Embase， and Web of Science were searched for articles on the detection rate of postpartum depression in advanced maternal age in China by combining subject terms and free terms from inception to July 2023. The process of literature screening，data extraction and quality assessment were carried out by two researchers independently. Stata 16.0 software was used for data analysis. Results A total of 21 studies were included，with a total sample size of 5 163. The results of Meta-analysis showed that the overall detection rate of postpartum depression in advanced maternal age in China was 20.0%（95%CI=17.4%-22.6%）. The subgroup analysis revealed that the detection rate of postpartum depression was 19.5%（95%CI=13.8%-25.3%） in women < 40 years old，40.3% （95%CI=11.4%-69.3%） in women ≥ 40 years old，19.7%（95%CI=11.7%-27.7%） in women with high school education level or higher，30.7%（95%CI=19.1%-42.3%） in women with high school education level or lower，21.1%（95%CI=14.4%-27.9%） in primipara，16.2%（95%CI=12.9%-19.6%） in multipara，16.4%（95%CI=12.2%-20.6%） in natural childbirth， 27.8%（95%CI=20.9%-34.8%） in cesarean section，20.7%（95%CI=15.6%-25.8%） in women with male newborn and 27.3%（95%CI=20.5%-34.0%） in women with female newborn； there were 38.7%（95%CI=22.6%-54.8%） women with pregnancy complications，11.7%（95%CI=7.6%-15.8%） women without pregnancy complications，29.5%（95%CI=17.9%- 41.1%） women with adverse pregnancy and childbirth history，27.7%（95%CI=16.6%-38.8%） women without adverse pregnancy and childbirth history，18.0%（95%CI=16.5%-19.4%） published the year before 2020，19.5%（95%CI=18.0%- 21.0%） published the year after 2020，20.4%（95%CI=18.2%-22.6%） in the north and 18.2%（95%CI=17.0%-19.4%） in the south，20.0%（95%CI=18.5%-21.5%） in the Edinburgh Postnatal Depression Scale（EPDS） score ≥ 13 and 16.9% （95%CI=15.2%-18.5%） in the EPDS score ≥ 10.

Abstract： Background Postoperative sore throat （POST） is one of the common mild but unpleasant postoperative complications after general anaesthesia. There is evidence that Glycyrrhiza Radix can effectively reduce the incidence of POST，but its effective fraction remains unclear. Objective To screen the effective fraction of Glycyrrhiza Radix on preventing respiratory tract injury induced by endotracheal intubation. Methods From April 2021 to July 2022，60 SPF-grade Wistar rats were randomized into the control group，endotracheal intubation group，lidocaine group，total polysaccharides group，total saponins group，total flavonoids group based on random number table method，with 10 rats in each group. The endotracheal intubation model was prepared for all groups except the control group. Before intubation，each treatment group was sprayed with a solution consisting of 1% lidocaine，total polysaccharides，total saponins，and total flavonoids at 1 mL/100 g（by body weight）to permeate the uvula and peri-soft palate tissue of rats，respectively. The control and endotracheal intubation groups were sprayed with an equal volume of 0.9% saline. After 2 hours of mechanical ventilation，the endotracheal tube was removed，and the pharyngeal mucosa tissues and blood samples of rats were collected under deep anesthesia. Pathological changes of rat pharyngeal mucosa and the expression levels of Toll-like receptor 2 （TLR2） and Toll-like receptor 4 （TLR4） were observed by hematoxylin-eosin staining （HE staining） and immunohistochemistry （IHC）; the expression levels of inflammatory cytokines including serum tumor necrosis factor-α （TNF-α），interleukin-2（IL-2），interleukin-4（IL-4），interleukin-10（IL-10），superoxide dismutase（SOD），malondialdehyde（MDA），total antioxidant capacity（T-AOC），and stress hormones including cortisol（Cor），epinephrine （E），and norepinephrine（NE） were measured by enzyme-linked immunosorbent assay （ELISA）. Results HE staining showed mucosal shedding and severe damage of submucosal structure accompanied by a large number of inflammatory cells infiltrated in the endotracheal intubation group; while milder damage of mucosal structure and less inflammatory cells were significantly reduced in the total saponins group. ELISA results showed that compared with the control group，the levels of TNF-α and IL-2 in the serum of rats increased significantly，and the levels of IL-4 and IL-10 decreased significantly in the endotracheal intubation group （P<0.05）; compared with the endotracheal intubation group，the serum levels of TNF-α and IL-2 decreased，and the levels of IL-4 and IL-10 increased in the total saponins group（P<0.05）. Compared with the control group，the MDA level in the serum of rats was significantly increased，and the SOD and T-AOC levels were significantly decreased in the endotracheal intubation group（P<0.05）; compared with the endotracheal intubation group，the MDA level decreased and the levels of SOD and T-AOC increased in the total saponins and flavonoids groups（P<0.05）. Compared with the control group，serum Cor，E，and NE levels significantly increased in the endotracheal intubation group （P<0.05）; compared with the tracheal intubation group，serum Cor，E and NE levels were decreased in the total saponins group rats （P<0.05）. The IHC results showed that the average optical density （AOD） expressed by TLR2 and TLR4 in the endotracheal intubation group was higher than the control group（P<0.05）. The AOD expressed by TLR4 in the pharyngeal mucosal tissue of rats in the total saponins group was significantly lower than that of the endotracheal intubation group（P<0.05）. Conclusion Total saponin is the main effective fraction of Glycyrrhiza Radix for the prevention of respiratory tract injury caused by endotracheal intubation under general anesthesia.

Abstract： Star shaped block copolymer POSS-(PMMA-b-PS)8 was synthesized by a two step process of atom transfer radical polymerization (ATRP) with eight functionalized polyhedral oligomeric silisesquioxane POSS-(Cl)8 as core and poly(methyl methacrylate-b-polystyrene) as arm. The POSS-(PMMA-b-PS)8 was then sulfonation treated to produce hybrid polymer POSS-(PMMA-b-SPS)8, which was finally used as the polymer matrix for making proton exchange membranes (PEMs). The examination of conductivity as function of relative humidity for PEMs of high and low hydration status respectively indicated that with longer SPS block length exhibited higher proton conductivity for the PEMs of low hydration status with the same λ i.e. the number of water molecular coupled to sulfonic acid groups. TGA analysis showed that two kinds of PEM all exhibited higher water retention capacity and higher initial decomposition temperature. A well-connected ionic domains in PEM with longer SPS block could be observed by transmis-sion electron microscopy (TEM) and atomic force microscopy (AFM). The features of molecules motion of chain segments and spins relaxation time T2 for the PEMs of low hydration status were analyzed by low field nuclear magnetic resonance, and it is found that the well connected ionic domains could be observed also in the PEMs with longer SPS block, which exhibited higher proton spin-diffusion coefficient, therewith higher proton conductivity by low relative humidity.

Abstract： Objects in farmlands often have characteristic of small volume and high density with variable light and complex background, and the available object detection models could not get satisfactory recognition results. Taking bees as research objects, a method that could overcome the influence from the complex backgrounds, the difficulty in small object feature extraction was proposed, and a detection algorithm was created for small objects irrelevant to image size. Firstly, the original image was split into some smaller sub-images to increase the object scale, and the marked objects were assigned to the sub-images to produce a new dataset. Then, the model was trained again using transfer learning to get a new object detection model. A certain overlap rate was set between two adjacent sub-images in order to restore the objects. The objects from each sub-image was collected and then non-maximum suppression (NMS) was performed to delete the redundant detection boxes caused by the network, an improved NMS named intersection over small NMS (IOS-NMS) was then proposed to delete the redundant boxes caused by the overlap between adjacent sub-images. Validation tests were performed when sub-image size was set was 300�300, 500�500 and 700�700, the overlap rate was set as 0.2 and 0.05 respectively, and the results showed that when using single shot multibox detector (SSD) as the object detection model, the recall rate and precision was generally higher than that of SSD with the maximum difference 3.8% and 2.6%, respectively. In order to further verify the algorithm in small target recognition with complex background, three bee images with different scales and different scenarios were obtained from internet and test experiments were conducted using the new proposed algorithm and SSD. The results showed that the proposed algorithm could improve the performance of target detection and had strong scale adaptability and generalization. Besides, the new algorithm required multiple forward reasoning for a single image, so it was not time-efficient and was not suitable for edge calculation.

Abstract： The increasingly frequent illegal transactions hinder the secure transactions of Ethereum, and the anonymity of electronic currency makes it difficult to track and analyze illegal transactions. This paper used the transaction data of the Ethereum platform as the data source, the marked illegal account and unmarked normal account data set as the training set, and the characteristic attributes of the transaction data as the construction basis. Account for the overall forecast. The process uses the T-SNE algorithm to realize the dimensionality reduction and visualization of transaction features, adopts multiple cross-validation, and introduces the SHAP Value factor to judge the positive and negative attributes of the feature. The prediction effect accuracy rate of the established model reaches 94.29%. The evaluation metric for the area (AUC) value reached 0.9846. The proposed scheme can more accurately predict the illegal behavior on the Ethereum trading platform, and will effectively improve the blockchain-based trading environment.

Abstract：
Cognitive Diagnostic Computerized Adaptive Testing (CD-CAT) combines the advantages of cognitive diagnosis and CAT, which could improve the efficiency and accuracy of CD-CAT. CD-CAT can be divided into two types: dichotomous and polytomous. Presently, the majority of researches on CD-CAT are based on dichotomous CD-CAT. However, among the practical tests in psychology and education, there are many polytomous items, which can be further divided into nominal polytomous and ordinal polytomous items according to whether there is an order or grade between every response category. Nominal polytomous items are items whose response categories are independent and without orders or grades between every response category. Although researchers have developed (ordinal) polytomous CDMs and corresponding CD-CAT, few nominal CDMs and CD-CAT are based on nominal responses.
This study introduces seven commonly used item selection methods in dichotomous CD-CAT into NCD-CAT (CD-CAT based on nominal response models). PMR (pattern match ratio) and test efficiency index are evaluated under different conditions between these item selection methods. Here are details of two simulation studies below. Study 1 compared the performance of NR_PWKL, NR_PWCDI, NR_PWACDI, NR_MPWKL, NR_SHE, NR_MI, and NR_GDI methods under different test lengths (5, 10, 15, 20) and item pool qualities (high and low) in NCD-CAT. Results showed that: (1) the PMRs of NR_PWCDI, NR_PWACDI, NR_MPWKL, NR_SHE, and NR_MI are higher than or equal to that of NR_PWKL, especially in short tests. (2) as test length gets longer, that PMR advantage is missing, which is the same as the results of Zheng and Chang (2016). (3) compared to test length, item quality has a greater impact on PMR. For instance, with item quality descending, the PMR declined about 30% among all conditions. Study 2 is an experiment on variable-length NCD-CAT that was conducted to compare the performance of each item selection method under the conditions of three maximum posterior probabilities (0.8, 0.85, 0.9) and two item qualities (high and low). The results showed that: (1)under all experimental conditions the average test lengths of NR_PWCDI, NR_PWACDI, NR_MPWKL, NR_SHE, and NR_MI are shorter than that of NR_PWKL; the difference is more than 0.738. (2)affected by item quality, the average length of NR_GDI is smaller than that of NR_PWKL under high-quality conditions and larger than it under low-quality conditions.
To sum up, this study compared the performance of 7 commonly used item selection methods of dichotomous CD-CAT in NCD-CAT with different conditions (fixed and variable length). The simulation study showed that under most conditions, the NR_PWCDI, NR_PWACDI, NR_MPWKL, NR_SHE, and NR_MI methods performed well when compared to baseline algorithm NR_PWKL. This study has expanded the alternatives of item selection methods in NCD-CAT.

Abstract： The existing AdaBoost. M2 algorithm are insufficient in protocol traffic multiclass imbalance to solve the problem. So, this thesis proposes an ensemble algorithom called RBWS-ADAM2 for the classification of multiclass internet traffic. During each iteration of AdaBoost. M2, this algorithm preprocessed the training dataset by randomly balanced resampling, this strategy changed the number of majorities and minorities by randomly setting the sampling balance point to build multiple different training datasets. Moreover, this strategy toke sample weight as the basis for sample screening to strengthen the learning of this kind of sample. The experimental comparison of RBWS-ADAM2 algorithm and other similar algorithms on the internationally published protocol traffic datasets shows that, compared to other algorithms, the proposed RBWS-ADAM2 algorithm not only improves the F-Measure of most minorities, but increases the overall G-mean and the overall average F-measure effectively, and obviously enhances the overall performance of the ensemble classifier.
