Objective: To study the effect of parent's education on the early intellectual development of infants. Methods: A total of 3,000 infants in a general hospital were sampled and divided into three groups: 3-month-old, 6-month-old and 9-month-old. All of the infants were tested with DST. Results: The parent's education was shown to have a significant effect on the intellectual development of 6-month-old and 9-month-old infants. The better education the parents had, the brighter the infants were. Conclusions: The parent's education had significant effect on the baby's early intelligence development.

Objective:To study intelligent development of infant and related factors Method:3000 infants collected were striated by age The research instrument was DST Result:In the groups of 6-month old and 9-month old, there were significant differences of DQ (development quotient) among infants with fathers of different educational levels Infants in 3-month and 9-month groups with father of different occupations showed different preferred intelligent areas Infants of all age groups showed different DQ with the difference of their mothers' occupations, while only in the groups of 6-months and 9-months, mother education had influence on DQ of their infants Conclusion:Parents' educational level and occupation have influence on intelligent development of their infants

Objective To investigate the prevalence and resistance mechanisms of Proteus mirabilis in the ward of neurology de‐partment of our hospital .Methods For a total of 20 clinic isolates of Proteus mirabilis ,PCR were used for the detection of AmpC , ESBLs ,KPC and MBLs and then DNA sequencing was performed .The integrons were also detected by using PCR and then sequen‐cing was carried out .The genetic relationship between isolates were detected and analysed by pulsed‐field gel electrophoresis(PF‐GE) .The results of drug sensitivity tests were analysed .Results TEM‐1 and CTX‐M‐14 gene were found in all the 20 isolates ,the 10 isolates of Proteus mirabilis were also found carrying CMY‐2 gene .Class Ⅰ integrons were amplified from 19 strains carrying gene cassettes aacA4+cmlA1,dfrA12+orfF+aadA2and dfrA32+ereA+aadA2 respectively .PFGE analysis revealed that the 20 isolates were grouped into 11 PFGE types P1-P11 ,the 12 isolates of P1-P3 were same clones .The sensitive rates of the i‐solates to Meropenem ,Amikacin ,Aztreonam ,Ceftazidime and Tazocin were high .Conclusion Nosocomial transmission of the same clone of Proteus mirabilis was appeared in the ward of neurology department of our hospital .The predominance drug‐resistance genes were CTX‐M‐14 andCMY‐2 .The incidence of carrying class Ⅰ integrons was high ,and the major gene cassettes wereaacA4+cmlA1and dfrA12+orfF+aadA2.The 20 isolates were all sensitive to Meropenem ,Amikacin and Aztreonam .Other Clinical departments should also pay attention to the nosocomial infection caused by Proteus mirabilis and strengthen the infection control measures .

Under the background of globalization, public health issues are becoming more and more complicated. In the international arena, global health has gradually replaced international health and "global public health" as one of the dominant terms in the field of public health. However, until now, there is no unified understanding and definition for the concept of global health domestically and internationally. In this article, various foreign experts 'views and domestic experts' opinions about the concept of global health are collected and solicited, in order to generalize appropriate Chinese definition of global health of China.

OBJECTIVE: To explore the genetic basis for a child with unexplained global developmental delay (GDD), seizure, and facial deformity. METHODS: Whole exome sequencing (WES) was carried out for the patient. Candidate variants were verified by Sanger sequencing of the patient and his parents. RESULTS: WES revealed that the patient has carried a previously unreported de novo heterozygous nonsense c.4906C>T (p.Arg1636Ter) variant of the KMT2A gene, Based on the American College of Medical Genetics and Genomics standards and guidelines, the c.4906C>T variant of KMT2A gene was predicted to be pathogenic (PVS1+ PS2+ PM2+PP3). CONCLUSION The heterozygous nonsense c.4906C>T (p.Arg1636Ter) variant of the KMT2A gene probably underlay the disease in the child. Above finding has enriched the spectrum of pathogenic variants of the KMT2A gene.

Freshwater snail is an important biological group in aquatic ecosystem and an intermediate host of many parasites. Intestinal flora plays an important role in animal energy metabolism and resistance to pathogens. We analyzed the intestinal microbiota diversity of Radix auricularia (RA) and Planorbella trivolvis (PL) by 16S rRNA high-throughput sequencing. At the phylum level, RA had 23 phyla, including Proteobacteria (33.63%), Cyanobacteria (15.33%), Chloroflexi (13.95%), and Actinomycetes (12.99%). PL had 13 phyla, including Proteobacteria (54.88%), Bacteroidetes (28.49%), and Actinomycetes (7.65%). At the genus level, there were 445 genera in RA, including Pleurocapsa, Thiodictyon, Leptotrichia, and Nocardioides. There were 238 genera in PL, including Cloacibacterium, OM60NOR5_clade, Pseudomonas, and Rhodobacter. Ninety-three genera were the common core flora of the two snail species (all the samples were present), and 27 genera had an abundance greater than 0.5%. The structure of intestinal microbiota was significantly different between the two groups (P=0.027). We performed the functional prediction of intestinal microbiota using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt), and the results show that the KEGG functional composition of the intestinal flora of the two snails was similar, and the abundance of the amino acid metabolism, carbohydrate metabolism and membrane transport were large. In summary, the intestinal microbiota of the two snails was high in diversity and significantly different, but there were a large number of common core flora.
