Objective:To investigate the characteristics of implicit memory and its related factors in schizophrenic patients with negative and positive symptoms.Methods:Ninety-three schizophrenic patients (including 52 cases of negative symptoms group and 41 cases of positive symptoms group) and 30 normal controls (normal group) were tested with the method of Chinese character word completion method. The reaction time and correct rate were recorded and compared with analysis of variance and t-test, and the correlation with demographic factors was analyzed with Pearson correlation analysis. Results:Accuracy of implicit memory test in schizophrenia group: there were statistically significant differences in the accuracy of patients with different course of disease (≤5 years: (38±5)%, 5-15 years: (34±8)%, ≥15 years: (34±7)%, P<0.05).The differences were statistically significant in the accuracy of patients with different education levels(primary school: (35±6)%, junior and senior high school: (34±7)%, secondary college education and above: (39±5)%, P<0.05).The accuracy of patients with education years < 10 years ((34±7)%) was significantly lower than those with education years ≥10 years ((37±6)%, P<0.05).Reaction time results of implicit memory test in schizophrenia group : there were significant differences in reaction time of patients with different disease course(≤5 years: (3 248±971)ms, 5-15 years: (3 515±672)ms, ≥15 years: (3 925±842)ms, P<0.05).The differences were statistically significant in the reaction time of workers ((3 495±712)ms), farmers ((3 870±878)ms) and soldiers ((3 024±924)ms, P<0.05).The reaction time of patients with clozapine ((3 869±871)ms) was significantly higher than that of patients with olanzapine ((3 393±626)ms, P<0.05).Intergroup results of accuracy: the accuracy of normal control group ((40±5)%) was significantly higher than that of negative symptom group ((33±7)%, P<0.01).The accuracy of negative symptom group was significantly lower than that of positive symptom group ((37±6)%, P<0.01).Intergroup reaction time results: the reaction time of normal control group ((2 660±667)ms) was significantly lower than that of negative symptom group ((3 678±951)ms, P<0.01) and positive symptom group ((3 072±865)ms, P<0.05).The reaction time of negative symptom group ((3 678±951)ms)was significantly higher than that of positive symptom group( P<0.01).There was significant negative correlation between the accuracy of implicit memory and the course of disease in schizophrenia ( r=-0.22, P<0.05). Conclusion:The implicit memory of schizophrenic patients is related to the course of disease, taking drugs, and occupation.There may have differences in implicit memory between patients with negative and positive symptoms of schizophrenia.

Objective:
To explore ethnic distribution characteristics of SNPs associated with micronutrient deficiency risk of Chinese primary and middle school students, and to provide a basic reference for evaluating the risk of lack in micronutrient.
Methods:
Totally 143 SNPs reported in previous studies were collected, and DNA was exacted by using magnetic beads in frozen blood cell samples from the 2016 nutrition health survey project of 1 130 primary and middle school students, competitive allele method was used to detect SNP genotyping. GO significant enrichment analysis R software package to PCA, kinship and linkage disequilibrium analysis were used for analysis of features of candidate SNPs. If there was a population structure, the FaST-LMM model was used for correlation analysis.
Results:
The GO significant enrichment results showed that differentially expressed genes were mainly enriched in the biological process grouping, including catalytic activity, transport activity, energy metabolism pathway, steroid hormone, coenzyme, biological processes of vitamin A, D and metabolism of water-soluble vitamins, involving transcription, translation and energy metabolism related genes. The results of 143 SNPs showed statistically significant differences in ethnic distribution, and SNPs on chromosome 3 presented significant differences among ethnic groups. Principal component analysis 1 showed that rs1799852 on TF gene had 25%-50% explanatory validity, rs2118981 on RBP2 gene and rs1830084 on SRPRB gene had 50%-75% explanatory validity, rs1358024, rs1525892, rs1880669, rs3811647, rs3811658, rs6794945, rs7638018 and rs8177248 on TF gene had more than 75% explanatory validity.
Conclusion
SNPs associated with micronutrient deficiency risk of Chinese primary and middle school students are characterized with ethnic distributions.

Abstract
Biomarkers could improve the understanding of the causes of obesity and its association with chronic diseases for people. The purpose of the review is to summarize recent advances in transcriptomic, proteomic, and metabolomic phenotypic biomarkers of obesity in order to deepen the understanding of the etiology of obesity and its metabolic consequences. In the precise prevention and control of childhood obesity, different groups of biomarkers can improve the accuracy of the word "obesity" and help early detection of specific biomarkers with risk characteristics, so as to realize the transformation of childhood obesity from a one size fits all prevention and control strategy to a personalized prevention and control plan during the development of obesity.

Objective:
To evaluate anemia and related nutritional status of 6-17 years old boarding school students in rural areas of central and western China, and to reveal the difference of nutrition problems in different regions.
Methods:
In the central and western regions, Henan, Anhui, Jiangxi, Guangxi and Sichuan provinces, as well as Tibet Autonomous Region were selected for this survey considering similar per capita GDP levels. One secondary school and one primary school which participated in the National Nutrition Improvement Program for Rural Compulsory Education Students were selected from each province. One class was selected from each grade of every school by using cluster sampling method. A total of 2 180 students were selected in this survey. Venous blood was collected and the level of hemoglobin, ferritin, soluble transferrin receptor, folic acid and vitamin B12 was analyzed to evaluate anemia and nutrient deficiencies.
Results:
As for western region, prevalence of anemia among students aged 6-8 and 9-11 years was 3.2% and 2.9%, respectively; iron deficiency prevalence among students aged 6-8, 9-11 and 12-14 years was 10.8%, 13.8% and 24.3%, respectively; and folic deficiency prevalence among students aged 12-14 and 15-17 years was 32.7 % and 49.4%, respectively. Prevalence of anemia, iron and folic deficiency in those areas was significantly higher than those of central regions (all P <0.05). As for the central regions, vitamin B12 deficiency prevalence of students aged 6-8, 9-11, 12-14 and 15-17 years was 7.3%, 19.4%, 29.2% and 45.5% respectively, which was significantly higher than of those of the western regions at the same age group.
Conclusion
Anemia, iron deficiency and folic acid deficiency are more common among students in western region, while the vitamin B12 deficiency problem is more common in central region. There are regional differences in the nutritional problems of students in the rural areas of central and western part of China. Nutrition improvement of student needs to be adapted to local conditions.
