Objective To evaluate the nutritional status in maintenance hemodialysis patients using objective score of nutrition on dialysis.Methods Patients on maintenance hemodialysis were randomly selected and divided into three groups based on objective score of nutrition on dialysis:normal nutritional status group,moderate nutritional status group,and low nutritional status group.Logistic regression analysis was performed to identify factors of malnutrition.Furthermore,the results were compared with those of subjective global assessment.Results Totally 75 patients(male:female =1.13∶1)with a mean age of(54.90 ± 12.10)years and a mean vintage of (85.37 ± 54.17)months were enrolled.As determined by objective score of nutrition on dialysis,15 patients (20％)were divided into normal nutritional status group,42(56％)into moderate nutritional status group,and 18(24％)into low nutritional status group.Compared with the normal nutritional status group,the low nutritional status group had significantly different body mass index[(19.81 ± 2.22)vs(23.90 ± 2.44)kg/m2,P =0.030]and dry weight[(50.85 ± 7.60)vs(59.94 ± 10.89)kg,P =0.020].In addition,compared with normal nutritional status group,the moderate nutritional status group and low nutritional status group had significantly different total cholesterol[(4.60 ± 0.84)and(3.73 ± 0.68)mmol/L vs(5.71 ± 1.64)mmol/L,P =0.011,P =0.000],normalized protein catabolic rate[1.17 and 1.15 g/(kg · d)vs 1.45 g/(kg · d),P =0.030,P =0.010],triceps skinfold thickness[(1.44±0.77)and(1.00±0.41)cmvs(1.80±0.63)cm,P=0.032,P=0.020],mid-ann circumference[(24.85±1.48)and(21.66±1.48)cmvs(24.99 ±2.30)cm,P=0.046,P =0.037].Logistic regression analysis indicated C-reactive protein(OR =12.482,95％ CI =0.190-130.928,P =0.035)and normalized protein catabolic rate(OR =0.128,95％ CI =0.022-0.736,P =0.021)were significantly correlated with malnutrition.Conclusion Malnutrition is common in hemodialysis patients,with inflammation and low protein intake being its independent factors.

OBJECTIVETo investigate intake of water in different periods of a day of primary and middle school students in Beijing, Shanghai, Guangzhou and Chengdu of China.

METHODSA total of 5914 primary and middle school students from Beijing, Shanghai, Guangzhou and Chengdu were recruited using multiple-stage random sampling method from September to October 2011. Among them, 5868 students completed the survey. The information of amounts and types of drinking in 8 time periods, morning, afternoon, night as well as in meal and non-meal time in 24 hours of a day was recorded by subjects for seven consecutive days using a quantitative measurement. This information was analyzed by different periods.

RESULTSThe amount of drinking water among 8 periods of a day was (99 ± 101), (130 ± 106), (191 ± 155), (96 ± 107), (246 ± 172), (90 ± 101), (188 ± 135) and (50 ± 81) ml, respectively for before breakfast, during breakfast, after breakfast, during lunch, after lunch, during dinner, after dinner, and midnight (F = 1679.77, P < 0.01). Based on three periods of a day, the amount of drinking water in the morning (420 ± 242) ml was the statistically significantly most, followed by afternoon (341 ± 199) ml, and the least in the evening (327 ± 195) ml (F = 325.23, P < 0.01). The distribution trend of plain water in three periods was the same as total drinking water, with (270 ± 209), (250 ± 179) and (224 ± 177) ml, respectively (F = 84.89, P < 0.01) ; but beverage consumption was the most in the morning(151 ± 133) ml, then in the evening (103 ± 122) ml, and the least in the afternoon (91 ± 199) ml (F = 373.56, P < 0.01). The daily plain water consumption in meal time was (316 ± 247) ml, while it in non-meal time was (773 ± 445) ml with statistically significant difference (Z = 65.2, P < 0.01). There was no significant difference in meal time between plain water (165 ± 194) ml and beverage (151 ± 152) ml (Z = 0.59, P = 0.56) whilst plain water (579 ± 408) ml in non-meal time was significantly higher than beverages (194 ± 204) ml (Z = 64.5, P < 0.01).

CONCLUSIONThe amount of drinking water of primary and middle school students in different periods of a day was different in four cities of China.

To observe the contribution of FoxO1 on its downstream molecules expression and function in Jurkat cells,Jurkat cells were infected with FoxO1 expression lentivirus and interference lentivirus to establish FoxO1-KLF2-S1P1 signaling pathways mod-el.After infection of 120 h,FoxO1,KLF2,S1P1 and CD62L mRNA levels and the protein expression of FoxO1,FoxO1-p and KLF2 were increased (P<0.05) in FoxO1-overexpression group.Converse results(P<0.05) were observed in the interference group.The proportions of S1P1+cells were increased in both groups.It was notably that S1P1+cells were decreased(P<0.05) in interference group after infection of 72 h.The proportion of CD62L+cells was increased(P<0.05) in overexpression group,it was decreased(P<0.05) in the interference group.This vitro experiments showed S1P1 and CD62L could be regulated by FoxO1 lentivirus,and provided an experimental basis for research about intracellular FoxO1-KLF2-S1P1 signaling pathways and cellular functions.

Eosinophilic granulomatosis with polyangiitis(EGPA),also known as Churg-Strauss syndrome,is a clinically rare small-vessel vasculitis associated with antineutrophil cytoplasmic antibodies (ANCAs) and the hypereosinophilic syndromes (HESs),characterized by asthma,disseminated necrotizing vasculitis,extravascular granulomas,peripheral eosinophilia,and tissue eosinophilia. This article reviews the pathology,imaging,and clinical features of EGPA.
