Abstract： Background In the face of the serious challenges posed by the high prevalence of chronic diseases among the elderly and the coexistence of multiple chronic diseases，the health problems of community-dwelling elderly people' with multimorbidity require urgent attention. The comorbidity management model is being explored and practiced. Disease experience，as self-reported health information from patients，is expected to become a key component of the patient-centered community multimorbidity management model. Objective This study aimed to gain a deeper understanding of the real disease experience of community-dwelling elderly people with multimorbidity and provide a basis for personalized health management and supportive strategies of the group. Methods This study used purposive sampling and maximum difference sampling to select eligible interviewees from four communities under the jurisdiction of a community health service center in Zhengzhou City from August to September in 2022. Based on the principle of information saturation，20 subjects were ultimately included. Based on the research objective，literature review，and expert consultation results，the preliminary interview outline was formulated， and the final interview outline was determined after interviewing 2 patients. Semi-structured interviews were conducted with the study participants，guided by the phenomenological research methodology. Golaizzi analysis was used to analyse the data. Results Four themes and eleven sub-themes had been extracted from this study，including mainly long-standing symptomatic distress（physical dysfunction，fatigue，sleep disorders，and pain），negative psychological experiences （feelings of helplessness and worry about future life，reduced sense of social value and self-identity，and loneliness with altered social activities）， positive mindset of coexisting harmoniously with multimorbidity（being grateful for being satisfied，and positively adapting）， and aspirations in times of adversity（hoping for improvement in functioning，and seeking multi-directional social support）. Conclusion Physical dysfunction，sleep disturbances，fatigue，and pain are the most concerning health disturbances for community-dwelling elderly people with multimorbidity. The symptom management and multiple social support of the multimorbidity need to be strengthened. In the future，it is expected that multidimensional data would be used for dynamic health assessment to explore the common and individual patterns of multimorbidity，and to achieve precise management and intervention of elderly multimorbidity in the community.

Abstract： Anodic oxide films on Al-alloys were sealed by aluminum phosphate to further improve their corrosion resistance. Electrochemical impedance spectroscope (EIS) was used to study the effect of the sealing treatment on corrosion resistance of the anodic oxide films in comparison with those sealed with boiling water and cerium salt solution respectively. The results showed that, the aluminum phosphate coating was formed on the anodic oxide film sealed with aluminum phosphate, and it could provide the anodic oxide film the best corrosion resistance superior to those sealed with boiling water and cerium salt solution. Furthermore, the effectiveness of the aluminum phosphate treatment could last longer than that of sealing treatmants with boling water and cerium salt solution. This method could be a new sealing treatment for anodic oxide film on Al-alloys.

Abstract： The effect of nanocrystallization on the adsorption of Cl- on Fe20Cr alloy in [Cl-] =0.1 mol/L borate buffer solution was investigated by means of X-ray photoelectron spectrum(XPS) and calculations per the first-principles. The results show that the influence of Cr on Cl- adsorption behavior could be described as the following two aspects : the one, in view of the calculation per the first-principles, is that the adsorption energy decrease with the increasing Cr content at the interface of passive film/alloy, which is conducive to the adsorption of Cl-; the other is that the Cr enrichment may also facilitate the formation of passivation film, which inhibit the Cl- adsorption. Nanocrystallization may enhance the diffusivity of Cr, which leads to the enrichment of Cr within the passive fil as well as at the interface of passive film/alloy. Thus, nanocrystallization can inhibit the adsorption and the inward migration of Cl- , and finally enhance the corrosion resistance of the alloy.

Abstract： A gradient nanostructured (GNS) surface layer was fabricated on a Z5CND16-4 martensitic stainless steel by means of surface mechanical rolling treatment (SMRT). The microstructure in the GNS surface layer was characterized by using SEM and TEM. The results showed that the mean grain size increases with depth, from about 25 nm at the topmost surface layer to the initial value in the matrix. The total thickness of the grain-refined layer is about 150 mm. The electrochemical corrosion property of the SMRT sample was compared with that of the as-received sample in a 3.5%NaCl aqueous solution. It is shown that the pitting corrosion potential increases from about 0.179 V in the as-received sample to about 0.313 V in the SMRT sample, and the self-corrosion potential also increases evidently. The formation of nanostructures, the increased structural homogeneity, and the introduction of compressive residual stresses in the GNS surface layer, as well as the decreased surface roughness, were discussed to promote the pitting corrosion resistance of the SMRT sample.

Abstract： Objective To investigate the expression of microRNA-107 (miR-107) and its functional role in hepatocellular carcinoma (HCC). Methods The gene chip data of HCC obtained from the Gene Expression Omnibus (GEO) database and the Cancer Genome Atlas (TCGA) database were used to analyze the expression levels of miR-107 in liver cancer. Twenty-two pairs of fresh surgical specimens of HCC and adjacent tissues and 53 paraffin-embedded specimens of HCC were examined for miR-107 expression by qRT-PCR. The correlation of the expression levels of miR-107 with the clinicopathologic characteristics of the patients were analyzed. The role of miR-107 in regulating the proliferation of hepatocellular carcinoma cells were determined by MTT assay in Huh7 cells transfected with a miR-107 mimic or inhibitor. Results The expression levels of miR-107 were significantly up-regulated in HCC tissues as compared to the adjacent tissues (P<0.05) in positive correlation with the tumor size (P<0.032). Transfection with miR-107 mimics significantly promoted the cell proliferation (P< 0.0001) while miR-107 inhibitor inhibited the cell proliferation (P<0.0001). Conclusion The expression of miR-107 is upregulated in HCC tissues and its expression levels are correlated with HCC cell proliferation, suggesting its role as a potential oncogene in liver cancer.

Abstract：在含有不同C3H8O3含量的硅铝复合电解液中，利用交流脉冲电源在AZ91D镁合金基体上制备了一系列微弧氧化膜。利用扫描电镜、膜层测厚仪分别研究了陶瓷膜层的微观形貌特征及厚度；采用全浸泡试验和电化学阻抗谱测试了膜层在3.5%NaCl中性溶液中的耐蚀性能。结果表明，微弧氧化过程中的起弧电压和终止电压均随C3H8O3含量的增加而呈上升的变化趋势；随着C3H8O3含量的增加，膜层耐蚀性先提高后降低，膜厚的变化趋势基本与耐蚀性一致，但膜厚变化幅度不大。EIS测试结果表明，膜层的耐蚀性主要取决于内部致密层，当C3H8O3含量为5mL/L时，膜层相对较致密，因而表现出良好的耐蚀性能。
