Estimating individualized treatment rules by optimizing the adjusted probability of a longer survival.

Individualized treatment rules inform tailored treatment decisions based on the patient's information, where the goal is to optimize clinical benefit for the population. When the clinical outcome of interest is survival time, most of current approaches typically aim to maximize the expected time of survival. We propose a new criterion for constructing Individualized treatment rules that optimize the clinical benefit with survival outcomes, termed as the adjusted probability of a longer survival.

Application and study on preparation of bio-asphalt by modified phenolic resin from corn straw tar.

XPS, GPC, FT-IR, and GC-MS analyses were conducted on corn straw tar and 70# petroleum asphalt. The results indicate that the sulfur content in corn straw tar is lower than that in petroleum asphalt, potentially mitigating the volatilization of harmful substances upon substituting petroleum asphalt. This finding serves as evidence for the substantial presence of phenolic substances in corn straw tar.

Gender differences in symptom burden among people living with HIV/AIDS receiving antiretroviral therapy in Yunnan, China.

Little is known about gender differences in the symptom burden of people living with HIV/AIDS (PLWHA) on antiretroviral therapy in China. This study was conducted based on a biopsychosocial-medical model to describe gender differences in symptom burden among 1035 PLWHA in Yunnan Province, China. After propensity score matching, 798 PLWHA were included in this analysis.

Measuring care-related regret intensity: Reliability and validation of a 10-item scale among Chinese nursing interns.

Aim: The 10-item care-related regret intensity scale (RIS-10) assesses the experience and intensity of care-related regrets. The aim of this study was to validate a Chinese version of the RIS and examine its reliability and validity when applied to Chinese nursing interns.

Background: Nursing students, the future healthcare workforce, often face clinical errors and adverse events due to limited knowledge and experience.

Restricted survival benefit with right-censored data.

The hazard ratio is widely used to quantify treatment effects. However, it may be difficult to interpret for patients and practitioners, especially when the hazard ratio is not constant over time. Alternative measures of the treatment effects have been proposed such as the difference of the restricted mean survival times, the difference in survival proportions at some fixed follow-up time, or the net chance of a longer survival.

[Spatiotemporal variability characteristics and driving forces of land use in the Pan-Pearl River Basin, China].

The Pan-Pearl River Basin is a bridgehead for China's reform and opening-up and the construction of the Belt and Road at Sea, with vital strategic significance in Chinese overall development. Land use data and climate and socio-economic indicators were integrated to probe the spatiotemporal change and its driving forces of land use in the Pan-Pearl River basin with ArcGIS spatial analysis tool and SPSS factor analysis tool. Results showed that land use in the Pan-Pearl River Basin significantly changed between 1990 and 2015, with decreases of the area of paddy field and woodland and rapid increases of urban land and other construction land.

Chronic Intermittent Hypobaric Hypoxia Pretreatment Ameliorates Ischemia-Induced Cognitive Dysfunction Through Activation of ERK1/2-CREB-BDNF Pathway in Anesthetized Mice.

Chronic intermittent hypobaric hypoxia (CIHH) has protective effects on heart and brain against ischemia injury through mobilizing endogenous adaptive mechanisms. However, whether CIHH prevents against cognitive impairment was not elucidated. The present study aimed to investigate the effect and mechanism of CIHH treatment on ischemia/reperfusion (IR)-induced cognitive dysfunction.

Chronic intermittent hybobaric hypoxia protects against cerebral ischemia via modulation of mitoK.

Objective: Providing adequate protection against cerebral ischemia remains an unrealized goal. The present study was aimed at testing whether chronic intermittent hypobaric hypoxia (CIHH) would have protective effects against cerebral ischemia and investigating the potential role of mitochondrial membrane ATP-sensitive potassium channel (mitoK) in this effect.

Methods: Ischemia was induced in rats by occlusion of bilateral common carotid arteries for 8min on day 2 after bilateral vertebral arteries were permanently electrocauterized and CIHH was simulated in a hypoxic chamber.
