Abstract?AIM:To study the Influence and outcomes of eye healthcare information teaching for the visual development of children under“combination of medicine and education” in kindergartens.?METHODS:The children(5-6 years old) were randomly selected from 6 kindergartens in Nanjing, 3 in Yuhua District as the experimental group, and the other 3 in Jianye District as the control group.A one-year follow-up was conducted to evaluate the difference of visual development, including the rate of low vision, rate of referral caused by refractive abnormality, rate of astigmatism, the average of the equivalent spherical lens and the rate of lacking physiological hypermetropia, between the experimental group and the control group children.?RESULTS:One school year later,the rate of low vision, rate of referral caused by refractive abnormality and the rate of astigmatism, were significantly lower (P<0.05)in the experimental group under the mode of“combination of medicine and education”, which were also lower than those before experiment(P<0.05).The average of the equivalent spherical lens of experimental group increased and the rate of lacking physiological hypermetropia decreased significantly, compared with the control group ( P <0.05 ) and with those before experiment(P<0.05).?CONCLUSION:Using “combination of medicine and education” eye health care model,is good for children's visual development,so as to reduce the rate of low vision and delay the occurrence of myopia.

Premature and low birth weight children are susceptible to many unfavorable factors due to the immaturity of intrauterine development. Compared with term infants,they are inclined to suffer from refractive error,amblyopia,congenital eye disease,etc.,which affect vision development and even cause visual impairment. Therefore,administering eyesight care after birth for premature and low birth weight infants allows the early detection of disorders which can be given timely correction,maximizes the protection range and facilitates vision development. The quality of life is achieved with visual function improved. After-birth vision care is setted at hospital and family levels,which includes regular visits to the hospital for eye disease screening and vision monitoring,as well as family eye care from sleeping,diet,environment and eye-watching behavior and habits perspectives.

OBJECTIVETo study the genotype distribution of extended-spectrum beta-lactamases (ESBLs) in ESBLs-producing Escherichia coli (E. coli) isolates from posthepatitic cirrhosis' patients with bloodstream infection.

METHODSE. coli were isolated in bloodstream from patients with posthepatitic cirrhosis between January and December in 2011. The strains were identified by VITEK-II. The antibiol susceptibility tests were performed with K-B method. beta-lactamases genes were detected multi-PCR, PCR, sequence and blast.

RESULTSA total of 79 non-duplicate clinical isolates of E coli were consecutively collected from liver cirrhosis' patients with bloodstream infection. There were 20 isolates produced TEM-1 type beta-lactamases and 1 isolate produced SHV-1 typebeta-lactamases. 40 clinical isolates were detected to produce CTX-M type ESBLs, there were 20 CTX-M-1 group and 26 CTX-M-9 group, including 6 stains habouring both CTX-M-1 and CTX-M-9 group. Eight CTX-M genotypes were confirmed by sequencing of the PCR products, including CTX-M-3, CTX-M-14, CTX-M-15, CTX-M-24, CTX-M-28, CTX-M-31, CTX-M-65 and CTX-M-79.

CONCLUSIONCTX-M genotype ESBLs was the most popular extended-spectrum beta-lactamases in E. coli isolated from liver cirrhosis' patients with bloodstream infection. The CTX-M-14 is the dominant epidemic type.

Undifferentiated and differentiated 3T3-L1 adipocytes were treated with 100 ng/ml tumor necrosis factor-?(TNF-?),and peroxisome proliferator-activated receptor-?2 (PPAR-?2) mRNA expression and adiponectin secretion in cultured cells were measured.The results showed that TNF-?suppressed PPAR-?2 mRNA expression and adiponeetin secretion in 3T3-L1 adipocytes (P

OBJECTIVETo study the relationship between angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and left ventricular mass (LVM) in newborns admitted to the neonatal intensive care unit (NICU).

METHODSSeventy-two newborns admitted to the NICU were enrolled. ACE genotypes were determined by genomic DNA which was isolated from heel-prick blood. Disease status of the newborns was evaluated by the Neonatal Critical Score (draft) on postnatal day 1. LVM and LVM index (LVMI) were evaluated by echocardiography on postnatal days 1-3.

RESULTSDD genotype was identified in 11 cases, ID genotype in 31 cases, and II genotype in 30 cases. There were no significant differences in clinical characteristics, critical score and body measurements in newborns with different genotypes. The DD genotype group showed significantly lower LVMI than the group with ID+II genotypes (29±4 g/m2 vs 35±8 g/m2; P<0.05).

CONCLUSIONSACE gene polymorphism is associated with the LVMI in newborns admitted to the NICU. The LVMI of DD genotype carriers is significantly lower than that of ID+II genotypes carriers, which suggests that D allele may be associated with the growth and development of left ventricular.

OBJECTIVE: To investigate the physical development, incidence of common respiratory diseases, and motor development during infancy in preterm infants with bronchopulmonary dysplasia (BPD). METHODS: A retrospective analysis was performed on the clinical features and infantile outcomes of preterm infants with BPD who were admitted to the neonatal intensive care unit between January 2012 and December 2015. Preterm infants without BPD were used as controls who were admitted to the neonatal intensive care unit during the same period and had similar gestational age and birth weight. Physical development, number of hospital stays, the incidences of pneumonia and wheezing, and motor development during infancy were compared between the two groups. RESULTS: Compared with the control group, BPD infants had a significantly higher incidence of extrauterine growth retardation at discharge (48% vs 41%; P<0.05); BPD infants were more susceptible to pneumonia, wheezing, eczema and rhinitis; BDP infants also had a significantly higher number of readmissions due to respiratory tract infection (P<0.05). BPD infants had a significantly smaller head circumference than the control group at corrected ages of 3, 6, and 12 months (P<0.05). BPD infants had significantly delayed gross, fine, and overall motor development than the control group at corrected ages of 6 and 9 months (P<0.05). CONCLUSIONS Infants with BPD are susceptible to extrauterine growth retardation at discharge. Their head circumference growth is relatively slow. They are susceptible to pneumonia and wheezing during infancy. Moreover, they have delayed motor development when compared with those without BPD at corrected ages of 6 and 9 months.

To investigate the immune regulatory effects of human bone marrow mesenchymal stem cells on alloantigen T lymphocyte in vitro, human MSCs were isolated and expanded from bone marrow cells, and identified with cell morphology, and the phenotypes were assessed by immunohistochemistry and flow cytometry. As the stimulation factor of T lymphocytes proliferation, either PHA or dendritic cells isolated from cord blood were cocultured with CD2(+) T lymphocytes from peripheral blood mononuclear cells by magnetic beads with or without MSC in 96-well plats for seven days. T cell proliferation was assessed by [(3)H]-thymidine incorporation using a liquid scintillation counter. T cell subsets, Th1, Th2, Tc1 and Tc2 were analyzed by flow cytometry after co-culture of CD2(+) T cells with MSCs for 10 days. The results showed that a significant decrease of CD2(+) T cell proliferation was evident when MSC were added back to T cells stimulated by DC or PHA, and an increase of Th2 and Tc2 subsets were observed after co-culture of MSC with T lymphocytes. It is suggested that allogeneic MSC can suppress T cell proliferation in vitro and the cause of that was partly depend on interaction of cells and the alteration of T cell subsets.

OBJECTIVETo investigate genomic DNA imbalances in ependymomas (EDMs) and their correlations with the tumor histological types, grades, locations, patients' gender and age.

METHODSChromosomal gains and losses in 16 cases of EDM were analyzed using comparative genomic hybridization.

RESULTSChromosomal regional gain and loss were found in 15 and 13 of 16 EDM cases respectively including totally 24 regional gains and 19 regional losses in all the tumors studied. Both regional gains and losses were mostly seen in myxopapillary EDMs (MPE, WHO grade I), more commonly seen in cellular EDMs (CE, WHO grade II) and tanycytic EDMs (TE, WHO grade II) than in anaplastic EDMs (AE, WHO grade III). Some of the regional gains and losses appeared only in one subtype of MPE, CE, TE and AE cases resulting in development of specific imbalance profiles of certain subtype in these cases. MPE, CE and TE often had +7. Chromosomal +5 occurred only in MPE and CE, and -22q was only seen in CE and TE. AE frequently had +1q, but none had +5, +7, -4q, -19q and -22q. The frequencies of any regional gain or loss were not affected by patients' genders (P > 0.05). Chromosomal +1q and +7p happened predominantly in intracranial EDMs with an averagely onset age of

CONCLUSIONSThe frequencies of chromosomal imbalances in EDMs decrease as the tumor grade increases. Characteristic chromosomal imbalances in each subtype may play an important role in determination of histological phenotypes and tumor grades. Chromosomal +1q, +5, +7p, +7, -4q, -19q and -22q are alterations which may dictate the biological behaviors of these tumors and the patients' prognosis.
