1.Significance of adaptive response to study of traditional Chinese medicine
Journal of Integrative Medicine 2004;2(6):415-20
Adaptive response is a topic of general interest in medical research. Utilization of adaptive response has become a new treatment strategy for some diseases, the core of which is to stimulate the mechanisms of body internal protection, to improve the adaptive and anti-injury capability, and to maintain the homeostasis of the body. The existence of adaptive response indicates that the body internal protection can be induced and its key mechanism is the inducement of internal protective factors (internal protective proteins). In this article, some connections between adaptive response and the theory of traditional Chinese medicine (TCM) were discussed, which indicated that adaptive response is much beneficial for explaining some theories of TCM such as correspondence between human and nature, strengthening healthy qi to consolidate constitution, acupuncture theory, adaptogen herbs, and treating disease before its onset, etc. Thus the adaptive response is of great significance for explaining scientifically the connotative meaning of the theories of TCM and for promoting the integration of TCM and western medicine.

Effects of preconditioning(PC) and praeruptorine C(Pra-C) on intracellular free calcium level([Ca2+]i) and NO content in hypertrophied vascular smooth muscle cells (VSMC) with hypoxia were studied. ①The aorta VSMC of rats with renovascular hypertension induced by two-kidney-one-clip(2K1C) were isolated and cultured. Fura-2/AM was as a calcium fluorescent indicator. It was seen that Pra-C(20 mg*kg-1*d-1,ig, for 9 weeks from week 9 after 2K1C) and PC (3 cycles of 5 min pure N2 and 5 min 95%O2+5%CO2) antagonisted the elevated activities(higher [Ca2+]i) induced by KCl and norepinephrine in VSMC with hypo- xia (30 min pure N2). ② In hypertrophied VSMC stimulated by angiotensinⅡ, combination of Pra-C(10 μmol*L-1 for 24 h) and PC enhanced NO content to the normal level in hypertrophied VSMC with hypo- xia. The results suggest that combination of Pra-C and PC have cooperative protection for hypertrophied VSMC with hypoxia injury.

Mycotoxins,secondary metabolites produced by certain fungi,have become one of the most harmful factors that affect the clinical safety of medicinal herbs that probably can be contaminated by harmful toxins generated from fungi in the whole process from planting to clinical use. Therefore,more toxicological research of mycotoxins,a better knowledge of the pathogenesis and quick detection with sensitivity and accuracy will play an important role in targeted therapy of poisoning by mycotoxins and early warning . In this paper,the current status of mycotoxin contamination in medicinal herbs was ana?lyzed,and the progress of toxicological study on common contaminants was reviewed. In view of the high toxicity of toxins,the strategy of ″Prevention First″ is highly desirable. Hence,the development of rapid detection of typical mycotoxins was systematically discussed. The review was intended to provide ref?erence for ensuring clinical safe administration of medicinal herbs and for reducing the risk of mycotoxin poisoning.

Objective To investigate the level of illness uncertainty among family members of patients in surgical intensive care unit (ICU) and analyze its potential influencing factors based on Mishel′s theory. Methods A sample of 260 family members were recruited from the surgical ICU during the period from September 2014 to June 2015. Illness uncertainty was assessed by the Mishel Uncertainty of Illness Scale-Family Member. General variables questionnaire, Social Support Rating Scale, Simplified Coping Style Questionnaire were also examined to explore the influencing factors. Results The score of illness uncertainty was ( 96.75 ± 13.90 ) points in family member of patients in surgical ICU, at a high level. Multiply liner regression showed that social support (P=0.011), positive coping style (P=0.027) and average family income (P=0.033) were significant influencing factors of illness uncertainty. Conclusions The level of illness uncertainty is high among family members of patients in surgical ICU. There is a need for nurses to provide accessible social support and psychological intervention, help them cope with illness uncertainty positively.
