BACKGROUND:Timely and scientific food supplement or fortified food could promote intellectual development.Xinjiang is located in the westem part of China where inhabited by minority nationalities.Ethnic minorities have their own unique lifestyle and dietary habits.Whether their unique ways will affect infant and child nutrition requires further study.OBJECTIVE:Through investigating the nutrition and intellectual development of 454 infants and children from Uygur,Han,Kazak nationality,to recognize the factors affecting intellectual development of children.DESIGN:Sample investigation.SETTING:Department of Nutrition and Food Hygiene,College of Public Health,Xinjiang Medical University.PARTICIPANTS:Totally 454 infants and children from Tulufan,Urumqi and Hutubi where inhabited by Uygur,Han,Kazak nationality were enrolled in the investigation from May 2004 to April 2005 after obtaining their family members'agreement.METHODS:The method was that one card for one people in the 454 infants and children,and the questionnaires included linking index,the social factors related to intellectual development,prandium history,the kinds and timing of supplementary food added,the timing to add supplementary food and so on.Denver Developmental Screening Test was used to measure the intellectual ability.MAIN OUTCOME MEASURES:The kinds and timing of supplementary food added,feeding patterns,mean score of intelligence in infants and children.RESULTS:Among the 454 included infants and children,12 were dropped out,because of unqualified data,so 442 were involved in the result analysis.①Adding supplementary food:Kazaks took milk product as dominant food,and meat.vegetables and fruits were added after one year old. Ugyurs took a little meat as main food,while the Hans took eggs and grains as dominant food.②Comparison of timing to add supplementary food:Mean timing to add supplementary food were 6.87, 5.40 and 8.17 months in Uygur,Han, Kazak nationality, respectively,and there were significant differences (F=14.62,P<0.01).③Intellectual development:The score of the three national infantile intellectual ability test was that:Hans>Uygurs>Kazaks,only when over 24 months year old Kazaks>Uygurs.There were significant differences (P<0.01).④Effect of different feeding ways and timing to add supplementary food on the development of intellectual ability:The earlier the timing to add supplementary food,the higher the score was (P<0.05).There was no significant difference in intelligent score of infants and children of different feeding ways (P>0.05).CONCLUSION:It is good for the development of intellectual ability that parents improve the lactating mother,infantile nutritional condition and add supplementary food(weaning food)in early age.

Objective To investigate the association between serum Klotho and oxidative stress in metabolically healthy obese individuals. Methods 180 physicalexamination subjects were investigated. They were devided into 3 groups:60 cases of normal weight and metabolic normality,60 cases of metabolically healthy but obese( MHO) ,60 cases of obesity with metabolic syndrome. Fasting blood glucose(FBG),2 h blood glucose(2 hBG),triglyceride ( TG) ,high densitylipoprotein cholesterol( HDL-C) , systolic blood pressure, diastolic blood pressure,body height, body weight,waist circumference,body mass index( BMI) were recorded. Malondialdehyde( MDA) ,superoxide dis-mutase( SOD) ,total antioxidation capacity( TAOC) ,Klotho were detected by ELISA. The difference of clinical pa-rameters,metabolic parameters,oxidative stress and Klotho among these three groups was compared by the methods of covariance analysis. Regression analysis and pearson correlation were used to evaluate the relationship of Klotho with oxidative stress. Results Compared with the control group, TAOC, SOD, Klotho were decreased significantly while MDA elevated significantly in both MHO group and obesity with metabolic syndrome group(P<0. 05). Com-pared with MHO group, TAOC, Klotho were significantly lower in obesity with metabolic syndrome ( P<0. 05 ) . Klotho protein was significantly positively associated with SOD, TAOC, negatively associated with waist circumfer-ence,BMI,FBG,2 hBG(r= -0. 182,-0. 225,-0. 221,-0. 202,-0. 188,P<0. 05). SOD,TAOC were deter-minants for Klotho. Conclusion The balancebetween oxidative and antioxidative system is disturbed in subjects with MHO. Klotho protein may maintain the normal metabolism of thebody by regulating the oxidative stress.

ObjectiveTo explore the effects of brucine on multiple myeloma (MM) and to compare the effects between brucine and bontezomib on MM.MethodsMTT method was used to determine the median inhibitory concentratiom (IC50) of brucine and bortezomib on the MM cell line U266.The supernatant of cultured U266 cell line was added to the culture system for inducing the differentiation of osteoblast cell line MC3T3-E1.After aseptic assay,RT-PCR was used to determine the RNA levels of alkaline phosphatase (ALP),osteocalcine (OC),osteoprotegerin (OPG) and recepter activator of NF-κB ligand (RANKL).Results IC50 of bortezomib on U266 cell line for 48 h was 22.4 nmol/L,and that of strychnine was 0.16 nmol/L.The mRNA levels of ALP,OC and OPG in osteoblast co-intervened by brucine combined with the supernatant of MM cells were higher than those in supernatant of U266 cells,while the level of RANKL mRNA was lower (P ＜0.05).The degree of increasing or reducing was greater than the level of control group intervened only by bortezomib (P ＜0.05).ConclusionThe therapeutic effects of brucine on MM might be carried out through the regulation of osteoclast by osteoblast,and the experiment confirmed that the therapeutic effect of brucine on MM was superior to that of bortezomib.
