Objective To investigate the influencing factors of ankylosing spondylitis(AS)patients’life quality and medical coping styles.Method Two hundred patients visiting at the outpatient department of our hospital took part in the assessment on AS life quality and medical coping styles to look into the living quality of AS patients and its medical coping methods and influencing factors.Results The total score on life quality was(66.82±5.57),among whose dimensions the psychological function was scored the lowest by(10.65±4.05). Pearson correlation analysis showed that the scores on confrontation of coping styles were positively related with the dimension of social function in life quality(r=0.18,r=0.13,P<0.05),the scores on the avoidance of coping style were positively related to the dimension of physiological function in the life quality(r=0.12,r=0.14,P<0.05),the scores on yielding in coping styles was negatively correlated to physiological function of the life quality(r=-0.20,P<0.05).Regression analysis results showed that the AS patients’life quality was impacted by the course of the disease,coping styles and modes for paying medical expenses(P<0.05).Conclusions The AS patients’life quality is low and it is related to their coping style,the course of the disease and modes for paying medical expenses.Medical personnel should implement targeted interventions to guide patients into taking correct medical coping styles according to the specific condition of patients,in order to improve their quality of life.

Potassium metabolism in young adult men exercising in the heat for six consecutive days and the effect of potassium deficiency in mice and rats induced by low potassium diet during heat exposure were observed. Increased potassium loss in sweat and lower potassium intake resulted in negative potassium balance. Individuals with a negative potassium balance had lower se- rum potassium levels and higher body temperature after exercise. Potassium deficient mice accomplished less work done (2.372 vs 4.253 Kg.M) but exih-ibited a markedly greater rate of heat gain (1.36 vs 0.87℃/Kg.M) as compared to the controls. The survival rate and cellular energy metabolism also decreasedThese observations suggest that prevention from potassium deficiency must be emphasized during prolonged physical activity under hot environments. According to the linear regression equations between potassium intake and balance, it is proposed that the potassium requirements in mild and medium physical activity in the heat are 40 and 60 mEq/day respectively, and the allowance of potassium in the latter may be 70-80 mEq/day.

Objective To investigate the association between the angiotensin-converting enzyme (ACE) I/D locus polymor-phism and migraine susceptibility .Methods The case control studies on the relation between ACE I/D gene polymorphism and mi-graine susceptibility published in the databases of PubMed and EMBAE were retrieved .The relationship between ACE 1/D poly-morphism and migraine was evaluated through the effect size (OR) and 95% confidence interval(CI) by fixed-effects model or ran-dom-effect models .Meanwhile the subgroup analysis of ethnicity and migraine types was performed .Results In meta analysis ,the homozygote model(DD vs .Ⅱ:OR= 1 .21 ,95% CI:1 .02-1 .44 ,P=0 .03 ;I2 =47% ) and dominant model all indicated that the ACE I/D polymorphism was positively correlated with the susceptibility of all migraine .The heterozygote model (DI vs .Ⅱ:OR=1 .35 , 95% CI:1 .06-1 .72 ,P=0 .02 ;I2 =10% ) and dominant model (DD+DI vs .Ⅱ:OR=1 .37 ,95% CI:1 .09 -1 .73 ,P=0 .00 ;I2 =40% ) indicated that ACE I/D polymorphism significantly increased the susceptibility of migraine with aura .Conclusion The ACE I/D locus polymorphism is correlated with migraine susceptibility ,its D allele is a risk factor of migraine ,which especially increases the susceptibility of migraine with aura .

Water eutrophication poses great threats to protection of water environment. Microbial remediation of water eutrophication has shown high efficiency, low consumption and no secondary pollution, thus becoming an important approach for ecological remediation. In recent years, researches on denitrifying phosphate accumulating organisms and their application in wastewater treatment processes have received increasing attention. Different from the traditional nitrogen and phosphorus removal process conducted by denitrifying bacteria and phosphate accumulating organisms, the denitrifying phosphate accumulating organisms can simultaneously remove nitrogen and phosphorus under alternated anaerobic and anoxic/aerobic conditions. It is worth noting that microorganisms capable of simultaneously removing nitrogen and phosphorus absolutely under aerobic conditions have been reported in recent years, but the mechanisms remain unclear. This review summarizes the species and characteristics of denitrifying phosphate accumulating organisms and the microorganisms capable of performing simultaneous nitrification-denitrification and phosphorous removal. Moreover, this review analyzes the relationship between nitrogen removal and phosphorus removal and the underlying mechanisms, discusses the challenges of denitrifying phosphorus removal, and prospects future research directions, with the aim to facilitate process improvement of denitrifying phosphate accumulating organisms.
