目的利用潜在类别分析法对脑卒中高危人群抑郁症状潜在类别进行探讨，并分析不同特征脑卒中高危人群抑郁症状的差异。方法使用一般资料调查表、患者健康问卷-9和社会支持评定量表对河南省多家社区卫生服务中心585名脑卒中高危人群进行调查，利用Mplus 8.3进行潜在类别分析，通过单因素分析和无序多分类logistic回归分析探究不同类别脑卒中高危人群抑郁症状的影响因素。结果最终共调查585例脑卒中高危人群，抑郁症状检出率为26.7%。脑卒中高危人群抑郁症状可分为：高水平-身心疲劳-专注困难抑郁型(C1,16.8%)、中水平-情绪低落抑郁型(C2,11.1%)、中水平-躯体疲劳抑郁型(C3,25.1%)、低水平-睡眠障碍抑郁型(C4,47.0%)。与低水平-睡眠障碍抑郁型脑卒中高危人群相比，女性(OR=0.473,95%CI:0.266～0.842)更容易归为中水平-情绪低落抑郁型，文化程度为初中及以下者(OR=2.684,95%CI:1.213～5.935)容易归为高水平-身心疲劳-专注困难抑郁型，社会支持水平低者(OR=0.941,95%CI:0.914～0.968)容易归为中水平-躯体疲劳抑郁型，具有≥5个脑卒中危险因素(OR=0.292,95%CI:0.123～0.697;OR=0.310,95%CI:0.122～0.788;OR=0.271,95%CI:0.122～0.599;OR=0.246,95%CI:0.104～0.579)、自评健康状况越差者(分别OR=2.197,95%CI:0.1.655～2.917;OR=0.1.353,95%CI:1.067～1.716)容易归于高水平-身心疲劳-专注困难抑郁型和中水平-躯体疲劳抑郁型。结论脑卒中高危人群抑郁症状具有明显的分类特征。临床医护人员应积极识别脑卒中高危人群抑郁症状特征，针对不同潜在类别制定及时有效的干预措施，以改善脑卒中高危人群的抑郁情绪。

Pine caterpillar moths, Dendrolimus spp. （Lepidoptera： Lasiocampidae）, are serious economic pest of pines. Previously, phylogenetic analyses of Dendrolimus using different methods yielded inconsistent results. The chemosensory systems of insects may play fundamental roles in promoting speciation. Odorant-binding proteins （OBPs） participate in the first step of odor detection. Studying the evolution of OBPs in closely related species may help us to identify their role in speciation. We identified three OBPs - one pheromone-binding protein and two general odorant-binding proteins - from male antennae of four Dendrolimus species, D. superans （Butler）, D. punctatus （Walker）, D. kikuchii Matsumura, and D. houi Lajonquiere, the olfactory recognition systems of which had not been previously investigated. We analyzed their molecular characteristics and compared their sequences to those of OBPs in D. tabulaeformis Tsai et Liu. Ka/Ks ratio analyses among the five Dendrolimus species indicate that PBP1 genes experienced more evolutionary pressure than the GOBPs. Phylogenetic relationships of PBP1 and GOBP1 both indicated that D. houi was the basal species, then branched D. kikuchii, while D. tabulaeformis, D. punctatus, and D. superans evolved more recently. These relationships are consistent with the changes in sex pheromone components of these five species. Dendrolimus tabulaeformis and D. punctatus are closely related sister species. However, the distances among GOBP2 sequences in the five Dendrolimus were very short, and the relationships of D. houi and D. la＇kuchii could not be resolved. Integrating our results with those of previous studies, we hypothesized that D. kikuchii, D. punctatus and D. superans evolved from the basal ancestor because of sex pheromone mutations and environmental pressure.

放牧是青藏高原高寒草地最主要的利用方式,牦牛和藏羊是青藏高原最常见的放牧家畜,家畜通过采食植物地上部分会使地上生物量减少,进而对植物群落氮库产生影响。本研究依托青海省高寒草地-家畜系统适应性管理技术平台的放牧试验样地,探讨不同家畜类型放牧对高寒草地植物群落氮库的影响。研究结果表明:未放牧处理下高寒草地地上生物量为180.0 g·m^(-2),藏羊单独放牧显著降低了植物群落地上生物量。对未放牧处理下不同功能群氮素含量的研究发现:豆科植物(26.4 mg·g^(-1))>杂类草(17.0 mg·g^(-1))>禾草(12.9 mg·g^(-1))≈莎草(11.8 mg·g^(-1))。放牧显著增加了禾草和莎草氮含量,对杂类草氮含量影响较小。放牧对群落水平植物地上部分氮含量的影响变化小于对各功能群的变化影响,因为植物群落具有稳定性。当高寒草地植物群落处于放牧压力下,会从土壤中获取更多的氮以维持生长,放牧会进一步加剧青藏高原高寒草地植物生长的氮限制。

目的探讨脑卒中半失能患者自我接纳的潜在类别并分析其影响因素。方法采用便利抽样法,选取河南省郑州市某2所三级甲等医院神经内科及神经康复科的308例脑卒中半失能患者为研究对象,采用一般资料调查表、自我接纳问卷、中文版事件相关性反刍性沉思问卷和慢性病自我效能量表对其进行调查。采用潜在剖面分析法分析患者自我接纳的潜在类别,采用无序多分类Logistic回归分析检验不同类别的影响因素。结果脑卒中半失能患者自我接纳分为3种类别:低接纳-低自评组(27.9%)、中等接纳-自评中庸组(43.8%)与高接纳-理性自评组(28.3%)。无序多分类Logistic回归分析结果显示,年龄、文化程度、家庭人均月收入、症状数量、侵入性沉思、目的性沉思以及慢性病自我效能是脑卒中半失能患者自我接纳潜在剖面分类的影响因素(P<0.05)。结论脑卒中半失能患者的自我接纳存在3种潜在类别,医护人员应重视年龄18~45岁、初中及以下文化程度、家庭人均月收入较低以及症状≥3个的脑卒中半失能患者,并通过减少患者的侵入性反刍、增强目的性反刍和自我效能感等干预措施来提升其自我接纳水平。

An effective and reliable prediction of the remaining useful life(RUL)of a tool is important to a metal forming process because it can significantly reduce unexpected maintenance,avoid machine shutdowns and increase system *** study proposes a new data-driven approach to the RUL prediction for metal forming processes under multiple contact sliding *** data-driven approach took advantage of bidirectional long short-term memory(BLSTM)and convolutional neural networks(CNN).A pre-trained lightweight CNN-based network,WearNet,was re-trained to classify the wear states of workpiece surfaces with a high accuracy,then the classification results were passed into a BLSTM-based regression model as inputs for RUL *** experimental results demonstrated that this approach was able to predict the RUL values with a small error(below 5%)and a low root mean square error(RMSE)(around 1.5),which was more superior and robust than the other state-of-the-art methods.

The induction of human immunodeficiency virus（HIV）-specific T-cell response is generally considered as critical to the development of effective immunity to HIV type 1 （ HIV-1 ）. Recombinant Avipoxvirus vectors are used widely for vaccination against HIV-1, where the induction of a cytotoxic CD8 ＋ T-cell（CTL） response seems to be an important component of protective immunity. A recombinant fowlpox virus（rFPV/Gag-pol） expressing the Gag-pol protein of HIV was constructed and characterized. The specific expression protein in CEF cells infected by recombinant fowlpox and the specific antibody in the sera of mice immunized with rFPV were analyzed via Western-blot.
