目的探究肺癌患者合并肺部感染的风险因素，构建和验证一个风险预测模型，使用现有的临床数据来预测肺癌患者的肺部真菌感染风险。方法这是一项回顾性研究，收集了2021年1月至2023年3月在中山市人民医院接受治疗的390例肺癌患者的信息，利用合并和不合并肺部真菌感染的肺癌患者人口统计学和临床特征来构建预测发生肺部真菌感染的列线图。所有患者按7：3的比例随机分为训练集和内部验证集两组，应用LASSO回归方法筛选变量和选择预测因子，并使用训练集的多元logistic回归方法构建列线图模型。通过计算受试者工作特征曲线下面积（AUC）确定模型的判断能力，此外，还对模型进行了校正分析和决策曲线分析（DCA）评价预测效果。结果LASSO回归筛选出14个潜在的预测因素，进一步的Logistic回归分析结果显示肝损伤、手术、贫血、低蛋白血症、疾病历程、侵入性操作、住院时间大于2周、全身糖皮质激素应用大于2周是肺癌患者发生肺部真菌感染的独立预测因素。根据这些变量建立了一个预测模型，该模型对训练集的AUC95%CI=0.980（0.973，0.896）和内部验证的AUC95%CI=0.956 （0.795，1.000），显示具有很高的区分度。训练集和验证集的校准曲线均基本沿45°线分布，DCA 曲线显示在阈概率为大于0.03时存在净获益。结论肺癌患者合并肺部真菌感染风险预测模型的构建和验证有助于临床确定高危人群，及早进行干预或调整治疗决策。

In order to meet the requirements from multi-hierarchical and multi-dimensional ground-screeding construction standard, a method of evaluating the design of ground-screeding construction robot based on fuzzy analytic hierarchy process was proposed. Firstly, four design schemes were presented according to practical requirements in ground screeding, and a multi-index model, based on analytic hierarchy process, was applied into the design scheme. Secondly, the weight matrix of indexes in every hierarchies was obtained based on the expert database founded on questionnaires and the fuzzy analytic hierarchy process was introduced to acquire a fuzzy-evaluation matrix of every indexes. Finally, a comprehensive fuzzy-evaluation vector was calculated by union operation with the weight matrix and the fuzzy evaluation matrix. The performances of four design schemes in different subordinate hierarchies under the same superior hierarchy and analyzes how the results come. In addition, the optimal results of the four design schemes under all evaluation indexes are contrasted and the final design scheme blending the four design schemes is proposed and a ground-screeding robot prototype made on the scheme is also presented in this paper.

Objective To evaluate the misdiagnosis rate of endometrial polyps by ultrasound imaging, and to explore simple, cost-effective, and time-saving ultrasound imaging methods to improve the diagnostic compliance rate of endometrial polyps. Methods A total of 484 patients with endometrial polyp ultrasound and pathological diagnosis in the Second People’s Hospital of Yunnan Province from January 2019 to May 2021 were included in the study. The patients were divided into two dimensional ultrasound group, color Doppler (CDFI) group and power Doppler (CDE) group. The pathological results were analyzed in different groups to find the misdiagnosis factors of endometrial polyps by ultrasound images. Results Compared with 2D ultrasound, CDE reduced the misdiagnosis rate [OR (95% CI)：0.172 (0.048～0.625)] .The misdiagnosis rates of the two-dimensional ultrasound group, CDE group, and CDFI group were 33.3%, 7.9%, and 46.0%, respectively (P < 0.001). Conclusions Based on two-dimensional ultrasound, the application of CDE can reduce the misdiagnosis rate of endometrial polyps and provide clinicians with valuable information in a short time.

Ga2O3 is an emerging wide bandgap semiconductor with potential applications in power and RF electronic systems. Previous studies have focused on β-Ga2O3 , and theoretical caculations have been made on the two-dimensional electronic gas (2DEG) in β-(Al xGa1 - x)2O3 / Ga2O3 heterojunction. In this paper, the effect of ε-(Al xGa1 - x )2O3 as a potential barrier on the electron transport properties of ε-(Al xGa1 - x)2O3 / ε-Ga2O3 heterojunction was studied. Firstly, the structure and properties of ε-(Al x Ga1 - x )2 O3 / ε-Ga2 O3 heterojunction are introduced. The charge density on the polarization surface caused by spontaneous polarization and piezoelectric polarization of ε-( Al x Ga1 - x )2 O3 / ε-Ga2 O3 heterojunction and the effect of polarization on the concentration of 2DEG were analyzed and calculated. Then, the relationship between ε-(Al x Ga1 - x )2O3 barrier thickness and alloy disorder scattering, interface roughness scattering and polar optical phonon scattering were analyzed under different Al mole composition. Finally, it is concluded that the interface roughness scattering and polar optical phonon scattering have important effects on the electron transport properties of ε-(Al x Ga1 - x )2 O3 / ε-Ga2 O3 heterojunction, and the alloy disorder scattering has little effect on the electron transport properties of ε-(Al x Ga1 - x )2 O3 / ε-Ga2 O3 heterojunction. The electron mobility of 2DEG concentration, alloy disorder scattering, interface roughness scattering and polar optical phonon scattering are determined by the thickness of ε-(Al xGa1 - x)2O3 barrier layer and the Al mole composition.

Objective Methods A purposive sampling strategy was used to choose patients with delayed resolution after microvascular decompression for hemifacial spasm. The qualitative phenomenological study was conducted and two trained research nurses used semi-structured interview on 10 patients. Each interview was recorded on audiotape and later transcribed verbatim , and was stopped when the information reached a saturated level. The Colaizzi s 7-step analysis method was used to analyze the recording materials. Results There are four main themes: Treatment of disease and cognition; Psychological issues such as excessive negative expectation, expectation bias, autosuggestion of surgery failure and positive coping style; Physical issuers such as headache, nausea and vomiting dizziness; incomprehension and support of social relations. Conclusion Patients with delayed resolution after microvascular decompression for hemifacial spasm suffered physical, mental and social stress. Medical staff should take a comprehensive dynamic evaluation on disease awareness, physical issues, psychological issues and social support system, try to understand the symptoms and psychological experience of patients, and provide professional guidance and individualized nursing intervention, in order to relieve discomfort, improve the mental health, and improve the satisfaction and therapeutic experience of patients. To investigate the symptoms and psychological experience of patients with delayed resolution after microvascular decompression for hemifacial spasm, in order to improve the medical staff awareness of patients ‘symptoms and psychological experience after surgery, and provide reference for improving nursing procedures of symptoms management and psychological care.
