The aluminum stress in acidic soil areas of China is an important abiotic stress factor that hampers the normal growth and development of plants and seriously affects the agricultural yield. The forms of plant resistance to aluminum stress are complex and diverse, which include secretion of organic acids, increase of rhizosphere pH, secretion of mucus, cell wall fixation of Al3+, organic acid chelation of Al3+ in cell solute, and vacuolar area isolation. Most of studies focus on analyzing conventional physiological characteristics, but in-depth molecular biological analyses are lacking. This review summarizes the mechanisms how plants adapt to acidic aluminum stress. This includes the effect of acid aluminum stress on plant growth and physiological metabolism, the two main physiological mechanisms of plant adaptation to acid aluminum stress (aluminum exclusion mechanism, aluminum tolerance mechanism), and the aluminum resistance related genes. Finally, this paper puts forward some prospects for further revealing the mechanism of plant adaptation to acid aluminum stress and excavating high-quality crops suitable for cultivation in acidic soils.

Intestinal adaptation is a spontaneous compensation of the remanent bowel after extensive enterectomy, which improves the absorption capacity of the remanent bowel to energy, fluid and other nutrients. Intestinal adaptation mainly occurs within 2 years after enterectomy, including morphological changes, hyperfunction and hyperphagia. Intestinal adaptation is the key factor for patients with short bowel syndrome to weaning off parenteral nutrition dependence and mainly influenced by length of remanent bowel, type of surgery and colon continuity. In addition, multiple factors including enteral feeding, glucagon-like peptide 2 (GLP-2), growth hormone, gut microbiota and its metabolites regulate intestinal adaptation via multi-biological pathways, such as proliferation and differentiation of stem cell, apoptosis, angiogenesis, nutrients transport related protein expression, gut endocrine etc. Phase III clinical trials have verified the safety and efficacy of teduglutide (long-acting GLP-2) and somatropin (recombinant human growth hormone) in improving intestinal adaptation, and both have been approved for clinical use. We aim to review the current knowledge about characteristics, mechanism, evaluation methods, key factors, clinical strategies of intestinal adaptation.

In industrial fermentation processes, bacteria have to adapt environmental stresses. Sometimes, such a self-adaption does not work and will cause fermentation failures, although such adaptation also can generate unexpected positive effects with improved fermentation performance. Our review introduces cell self-adaption to environmental variations or stress, process optimization based on such self-adaptions, with heterologous proteins production by Pichia pastoris and butanol fermentation as examples. Our review can sever as reference for fermentation optimization based on cell self-adaption.

Korean Journal of Women Health Nursing 2019;25(1):19-30
PURPOSE: To identify needs for pregnancy and postpartum adaptation of Chinese immigrant women and Vietnamese immigrant women in South Korea. METHODS: A descriptive research design was employed. Data were collected from 244 Chinese immigrant women and Vietnamese immigrant women from 3 provinces, 20 health care centers, and multi-cultural family support centers. Data were analyzed with descriptive statistics, t-test and ANOVA. RESULTS: An average score for needs perceived by Chinese immigrant women was significantly higher than that perceived by Vietnamese immigrant women. There were significantly differences in physical and emotional adaptation after childbirth, nutrition during pregnancy, cross cultural understanding and personal respect, and adaptation daily activity during pregnancy between the 2 groups. The highest score of needs in Chinese immigrant women was for nutrition during pregnancy and that in Vietnamese immigrant women was for baby rearing and family support. CONCLUSION: Based on needs of pregnancy and postpartum adaption, nursing intervention program in consideration of cultural characteristics of Chinese immigrant women and Vietnam immigrant women need to be developed for their pregnancy and postpartum health care.

6.The Breast Feeding Adaptation Scale-Short Form: Development and Testing of Its Psychometric Properties and Measurement Invariance
Child Health Nursing Research 2019;25(3):333-343
PURPOSE: This study sought to develop the Breastfeeding Adaptation Scale-Short Form(BFAS-SF) for use at 4 weeks postpartum, to test its validity and reliability, and to examine its measurement invariance. The latent mean score of the BFAS-SF across multiple groups was also compared. METHODS: This methodological research study was conducted to develop a short form of the BFAS and to test its psychometric properties and measurement invariance. Data were collected twice for measurement invariance testing. The sample included 431 and 272 breastfeeding mothers at 2 weeks and 4 weeks postpartum, respectively. RESULTS: Confirmatory factor analysis supported six dimensions of the BFAS-SF at 4 weeks postpartum. Multi-group confirmatory factor analysis revealed evidence for invariance of the BFAS-SF according to employment status, parity, delivery mode, and the postpartum period. There were statistically significant latent mean differences. Mothers who were unemployed and who had a vaginal delivery showed significantly higher scores for breastfeeding confidence, sufficient breast milk, and baby's satisfaction with breastfeeding. CONCLUSION: The BFAS-SF is valid, reliable, and an appropriate instrument for assessing mothers' breastfeeding adaptation. It can be used to compare mean scores according to employment status and delivery mode.

7.Cold-associated skin disorders
Journal of the Korean Medical Association 2019;62(4):193-196
The human capacity for physiologic adaptation to cold is minimal. A cold environment can be a threat to the skin, leading to a subsequent fall in core body temperature. Many physiologic, behavioral, and environmental factors predispose to the global effects of cold injuries. Physical injuries caused by cold have two forms: systemic forms such as hypothermia and localized forms such as frostbite. Reduced temperature directly damages the tissue, as in frostbite and cold immersion foot. Vasospasm of vessels perfusing the skin induces chilblain, acrocyanosis, and frostbite. The degree of damage caused by cold is related to four factors: temperature, exposure time, wind intensity (temperature sensation), and high altitude.

8.The Effects of Neurofeedback Training on Physical, Psychoemotional Stress Response and Self-Regulation for Late Adolescence: A Non-Randomized Trial.
Journal of Korean Academy of Nursing 2018;48(2):208-220
PURPOSE: The aim of this study was to analyze the effects of neurofeedback training for reducing stress and enhancing self-regulation in late adolescence to identify the possibility of use for nursing intervention. METHODS: A nonequivalent control group pre-post quasi-experimental design was used. Participants were 78 late adolescents assigned to the experimental group (n=39) that received the neurofeedback training and the control group (n=39). Data were collected on heart rate variability (HRV) and skin conductance level (SCL) to assess stress-biomarker response. The questionnaire contained 164 items from: Positive and Negative Affect Schedule (PANAS), Symptom Checklist-90-Revised (SCL-90-R) and Self-regulatory Ability scale. The neurofeedback training was based on the general adaptation syndrome and body-mind medicine. The intervention was conducted in a total of 10 sessions for 30 minutes per session with high-beta, theta and sensory motor rhythm training on scalp at central zero. RESULTS: There were significant difference in standard deviation of normal to normal interval (p=.036) in HRV and SCL (p=.029) of stress-biomarker response between the two groups. Negative affect (p=.036) in PANAS and obsessive compulsive (p=.023) and depression (p < .001) in SCL-90-R were statistically significant. Self-regulation mode (p=.004) in self-regulation ability scale showed a significant difference between the two groups. CONCLUSION: The results indicated that the neurofeedback training is effective in stress-biomarkers, psychoemotional stress response and self-regulation. Therefore, neurofeedback training using neuroscientific approach based on brain-mind-body model can be used as an effective nursing intervention for late adolescents in clinics and communities for effective stress responses.

9.How do precision medicine and system biology response to human body's complex adaptability?
Chinese journal of integrative medicine 2016;22(12):883-888
In the field of life sciences, although system biology and "precision medicine" introduce some complex scientifific methods and techniques, it is still based on the "analysis-reconstruction" of reductionist theory as a whole. Adaptability of complex system increase system behaviour uncertainty as well as the difficulties of precise identifification and control. It also put systems biology research into trouble. To grasp the behaviour and characteristics of organism fundamentally, systems biology has to abandon the "analysis-reconstruction" concept. In accordance with the guidelines of complexity science, systems biology should build organism model from holistic level, just like the Chinese medicine did in dealing with human body and disease. When we study the living body from the holistic level, we will fifind the adaptability of complex system is not the obstacle that increases the diffificulty of problem solving. It is the "exceptional", "right-hand man" that helping us to deal with the complexity of life more effectively.

We designed two types of pre-adaption plans for this study. One was a pre-adaption training with progressive intermittent hypoxia, with a constant lower pressure oxygen tank used in the plain before arriving at the plateau (PG). The other was by progressively increasing the time of exposure to hypoxia with oxygen supplied in stages after radical plateau (RG). By testing the blood oxygen saturation (SpO2), heart rate (HR), and quality of sleep after arriving at the 3800 m high plateau, results showed that the pre-acclimatization and radical groups performed better than the control group (CG). Both strategies were equivalent in terms of effects and principles in providing more flexible choices for acclimatization.
