目的了解接受抗病毒治疗HIV/AIDS患者抑郁状况及其影响因素。方法2022年7月-2022年9月，采用连续抽样法从南京市抗病毒治疗机构招募接受抗病毒治疗HIV/AIDS患者，进行匿名问卷调查，收集患者基本信息，采用患者健康问卷抑郁量表（PHQ-9）、简化的Berger艾滋病感知歧视量表（BHSS）及感知社会支持的多维度量表（MSPSS）调查抑郁状况、HIV耻辱得分以及社会支持水平等。采用多因素Logistic回归分析患者抑郁的影响因素。结果本研究共收集有效问卷1 879份，抑郁检出率为50.1%，多因素logistic回归分析结果显示：相较于初中及以下文化程度的患者，研究生及以上文化程度抑郁的风险更低［OR=0.534，95%CI（0.341，0.835），P=0.006］；相较于抗病毒治疗时长5~10年［OR=0.516，95%CI（0.379，0.702）］、>10年［OR=0.603，95%CI（0.375，0.969）］抑郁的风险更低；相较于中低社会支持水平，高社会支持水平是HIV/AIDS患者抑郁保护性因素［OR=0.430，95%CI（0.349，0.530），P＜0.001］；相较于未存在治疗药物副作用，存在药物副作用发生抑郁的风险更高［OR=2.260，95%CI（1.833，2.786），P＜0.001］；同时在HIV耻辱感量表得分越高，抑郁的可能性越高。结论南京市抗病毒治疗患者抑郁检出率较高，启动抗病毒治疗后应加强患者的药物副作用及心理状态监测，开展心理干预，缓解心理问题出现，提高患者的生命质量。

针对传统弹性光网络采用专用路径1+1保护策略存在资源浪费的问题，文章提出了一种共享链路保护策略。在检测到链路故障后，柔性光转发器切换至共享保护链路，并根据业务的优先级和请求频率重排业务权重，依据业务权重提供差异化的路由和频谱分配。此外，文章提出一种以物理网络拓扑结构、业务需求集合和优质业务量占比为约束条件，以最小化频谱隙利用率为目标，具有业务区分的路由和频谱分配方法。理论分析和仿真结果表明，与传统的1+1保护方法相比，所提保护策略在降低网络拥塞率的同时，可以最多节省38%的频谱资源，能够最大限度地实现备份频谱资源的共享。

A self-adaptive alternating direction multiplier method was designed for frictionless elastic contact problems. An augmented Lagrange function was introduced for the variational formulation of the problem with an auxiliary variable, to deduce a minimization problem and an equivalent saddle-point problem. Then the alternating direction multiplier method was used to solve the problem. To enhance the performance of the algorithm, a self-adaptive rule based on the iterative function on the boundary was proposed to automatically select the proper penalty parameter. The advantage of this algorithm is that, each iteration only needs to solve a linear variational problem and explicitly calculate the auxiliary variable and the Lagrange multiplier. The convergence of the algorithm was analyzed theoretically. The numerical results illustrate the feasibility and effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Background and purpose: The occurrence of lymph node metastasis in papillary thyroid cancer (PTC) can have adverse effects on the prognosis of patients. This study aimed to investigate risk factors related to the occurrence of contralateral central lymph node metastases (CLNM) and contralateral lateral lymph node metastases (LLNM) when imaging suspected ipsilateral LLNM in unilateral PTC. Methods: We retrospectively analyzed the clinical data of 526 patients who received surgical treatment in the same treatment group of Jiangsu Cancer Hospital Head and Neck Surgery Department from January 2011 to December 2021. They were initially treated with total thyroidectomy and bilateral central lymph node dissection (CLND) ± lateral lymph node dissection, and their postoperative pathology was uni-PTC. This study analyzed the relevant high-risk factors of contralateral lymph node metastasis. Results: Among the 526 patients, 295 had CLNM, including 272 ipsilateral CLNM, 129 contralateral CLNM and 106 of both sides CLNM; 165 patients had LLNM including 129 ipsilateral LLNM, 18 contralateral LLNM, and 18 of both ipsilateral and contralateral LLNM. Contralateral CLNM occurred in 65 (17.8%) of 365 patients who underwent preventive CLND, and contralateral CLNM was found in 68 (42.2%) of 161 patients with therapeutic CLND. Univariate and multivariate regression analyses showed that contralateral CLNM was associated with maximum diameter of tumor ≥2 cm, multiple foci, no Hashimoto's thyroiditis, tumor invasion, number of CLNM≥6 and age ＜55 years (P＜0.05). Maximum diameter of tumor ≥2 cm was related to contralateral LLNM (P＜0.05), while lymph extracapsular extension and lymph node metastasis at tumor side were independent risk factors for contralateral CLNM and contralateral LLNM (P＜0.05). Follow-up showed that 5-year overall survival (OS) rate was 97.9% and 5-year disease-free survival (DFS) rate was 97.5%. Conclusion: Contralateral CLNM is more likely to occur in patients with maximum diameter of tumor ≥2 cm, multiple foci, no Hashimoto's thyroiditis, number of CLNM ≥6, age ＜55 years, tumor and lymph extracapsular extension and lymph node metastasis at the cancer side. In clinical practice, bilateral CLND should be considered for patients with high-risk factors to reduce the residual recurrence of the tumor. Since metastatic rate of contralateral LLNM is relatively low, preventive contralateral lateral lymph node dissection should not be performed routinely when there are no high-risk factors mentioned above.

Flavonoids/anthocyanins, carotenoids and betalains are the main chemical substances for the coloration of flower petals. Among them, flavonoids/anthocyanins are the most widespread pigments determining the coloration of flower petals in most plants; whereas carotenoids play an important role in the color rendering of yellow to orange red petals in some specific plants. Betalains specially exists in some Caryophyllaceaes, including betaxanthins and betacyanins. At present, the molecular networks of their biosynthesis have been elucidated, and mainly controlled by a series of structural genes. Some regulators related to the pigment synthesis have been also identified in many plants. Moreover, the molecular breeding based on exogenous gene expression or endogenous gene editing have been successfully applied in the coloration improvements of some ornamental plants. In this review, the molecular basis, regulatory mechanism and molecular breeding application for the synthesis of three types of pigments in plants are systematically summarized. It is conducive for us to improve our understanding of the pigments synthesis-related regulatory network in plants, and expected to provide an theoretical support for future molecular breeding of flower colorations in ornamental plants.

Objective · To compare vitamin D levels in the patients with menstrually related migraine and those with non-menstrual migraine.Methods · A total of 100 patients with menstrually related migraine were enrolled as case group, and 100 patients with non-menstrual migraine were matched as control group in Renji Hospital, Shanghai Jiao Tong University School of Medicine, from June 2017 to June 2018. The patients’ information was collected and serum vitamin D levels were measured. Univariate analysis was performed to analyze the differences between the groups, and Logistic regression model was performed to analyze the relationship between menstrually related migraine and vitamin D levels. Results · Vitamin D levels were lower in case group than those in control group [ (13.48±5.02) ng/mL vs (14.93±4.94) ng/mL, P=0.042]. There were no statistically significant differences in other indexes between the groups (P>0.05) . Logistic regression analysis showed that the patients with vitamin D less than 10 ng/mL were more likely to have menstrually related migraine than those with vitamin D more than 20 ng/ml (OR=3.656, 95% CI 1.382-9.672,P=0.009) . In addition, there were no statistically significant differences in clinical characteristics and vitamin D levels between the patients with migraine occurring in premenstrual period and menstrual period (P>0.05) . Conclusion · Low vitamin D levels may be associated with menstrually related migraine, but not with its occurrence in premenstrual or menstrual period. [ABSTRACT FROM AUTHOR]

CVaR is an important risk measurement for portfolio investment. It is of great significance to select robust asset portfolio in a CVaR based model so as to reduce both the time cost on management and economic expenditure. Some studies have shown that the decision of asset portfolio under CVaR criterion can be transformed to a classical quantile regression. Motivated by this transformation, an adaptive Lasso quantile regression with a network structure is developed to select high-dimensional assets. Adaptive Lasso can impose a weighted constraint on the regression coefficients, theoretically presenting selection consistency. Network structure, which is constructed based on the complicated network theory, can reflect the complex dynamic relations among all the assets. It can also benefit to the model's variable selection performance. Computation is achieved by a linear programming method, and a two-step iterative approach is proposed to deal with some special computational problems for the CVaR portfolio investment decision. Simulation study under various scenarios shows that the proposed model performs best in terms of variable selection and prediction, and the advantage of network structure becomes more and more obvious with an increasing correlation between variables. An empirical study with 249 stocks is conducted. With a rolling regression technique, the proposed model presents great robustness and applicable significance. [ABSTRACT FROM AUTHOR]
