ObjectiveTo investigate the disinfection effects of two different methods on the ventilator circuits. MethodsThe ventilator circuits which had been used by patients were disinfected by the artificial brushing method and the strict program of the full automatic cleaning-disinfecting machine,respectively.Samples from circuits were cultured after disinfection,and the numbers of bacterium colony forming unit (CFU) were counted. ResultsThe qualified rate of disinfection of the ventilator circuits by the strict program of the full automatic cleaning-disinfecting machine was 100％,which was significantly higher than that by artificial brushing method.50 samples disinfected by artificial brushing method were selected,among which 14 samples had pathogenic bacteria.100 samples disinfected by the strict program of the full automatic cleaning-disinfecting machine were selected and total bacterial count≤5 cfu/cm2. ConclusionsThe sterilization of the ventilator circuits with the full automatic cleaning-disinfecting machine is effective and safe,which can make the disinfection work more standardized.

Objective To discuss the validity and the feasibility of modified specific immunotherapy of hypoglossis allergen in the treatment of children allergic asthma. Methods 100 children with allergic asthma were selected from October,2007 to April ,2008 in our hospital and divided into the observation group and the control group. The control group adopted routine method, the observation group made modifi-cation based upon routine nursing, placing emphasis on intervention of cognition and behavior of children and their parents, improvement of treatment compliance, whole- process, dynamic and continuous observa-tion of the treatment process, making individualized health education plan. The treatment compliance, total score of asthma control, and pulmonary function examination of impulse oscillation(IOS) were compared be-tween the two groups. Results The observation group was superior to the control group in treatment com-pliance, pulmonary function examination and the control results of asthma. Conclusions Specific im-munotherapy of hypoglossis allergen combined with modified nursing method can increase treatment com-pliance of children and lead to better results.

OBJECTIVETo study the mechanism underlying the effect of the SOCS3 rs4969170 A/G alleles on the occurrence of insulin resistance (IR) in patients with chronic hepatitis C.

METHODSThe promoter region of the SOCS3 gene was amplified by PCR,and luciferase expression vectors were constructed and transfected into HepG2,Huh7 cell lines.The relative luciferase activity of each expression vector was assessed by the dual luciferase reporter gene assay system.Western blotting was used to detect SOCS3 protein expression in PBMCs from groups of patients with the rs4969170 AA and AG genotypes.The state of IR in eight patients was evaluated by determining their HOMA-IR.

RESULTSThe pGL3-A, PGL3-G and pGL3-control vectors showed significantly different luciferase expression in the HepG2 cells (0.121 00 ± 0.022 07,0.027 00+/-0.012 49 and 0.043 33 ± 0.005 51; F =48.068, P=0.001) and in the Huh7 cell lines (0.164 70 ± 0.007 10,0.027 33 ± 0.017 04 and 0.033 67 ± 0.014 98; F =115.137, P=0.001). The expression of SOCS3 protein was significantly higher in the rs4969170 AA genotype group than in the AG genotype group (1.22 ± 0.40 vs. 0.30 ± 0.19; t =4.149, P=0.006).The IR index of patients with the rs4969170 AA genotype and the AG genotype was 4.11 ± 2.62 and 1.47 ± 1.01 respectively.There were three patients with IR in the rs4969170 AA genotype group and one in the rs4969170 AG group. There was no statistically significant difference between the two genotype groups (t=1.881, P=0.109).

CONCLUSIONSThe SOCS3 rs4969170 A haplotype may enhance transcriptional activity of the gene promoter to regulate gene expression, thereby increasing intracellular SOCS3 protein level and ultimately interfering with insulin signaling and causing IR in patients with chronic hepatitis C.

Objective: To understand the infection status, characteristics and drug resistance of non-O157 Shiga toxin-producing E. coli (STEC) in animal feces in Shandong Province. Methods: From 2015 to 2016, convient sampling method was used to collect 1 022 fresh feces of animals in Weishan county and Laizhou city, and 24 non-O157 STEC were isolated. The serotypes of non-O157 STEC strains were confirmed through serum agglutination test. The susceptibility was explored through the antimicrobial sensitivity experiments. ESBLs activity was confirmed by double-disc diffusion. PCR method was used to detect the resistance genes. PFGE typing was operated to assess the relatedness and variability of the strains. The multi-locus sequence typing (MLST) was adopted to get the allelic profile and ST sequence of strains. Analysis was made on the evolutionary relationship between different ST groups was made through CLC Sequence Viewer and Counting Express. Results: A total of 24 non-O157 STEC were isolated from animal feces. 23 strains were from pig feces, and 1 strain was from cow feces, and the serotypes were more dispersed. All of the 24 strains carried stx2 genes. The highest resistance rate was sulfamethoxazole(22 strains), the mount of cotrimoxazole and nalidixic acid was 18 strains, chloramphenicol was 13 strains, tetracycline was 19, and there was a phenomenon of multiple drug resistance. The drug resistance spectrum was sulfamethoxazole tetracycline-compound novammin-naphthidine-chloramphenicol. All strains were sensitive to cefepime and imipenem. The ESBLs confirmatory test showed that 4 strains of non O157 STEC produced beta lactamase. PCR detected 7 resistance genes, and 4 tetracycline resistance genes (Tet A, Tet B, tetC and tetD) were detected. The beta lactamase resistance genes (blaSHV-1, bla CTX-M, bla TEM) were all negative. 24 strains were divided into 15 PFGE types, and their clustering results were more dispersed and no dominant PFGE type. There were 11 kinds of MLST types, most of them are ST540 and ST5133 types, each of which was 4 strains, and clustered into 1 MLST genomes. Conclusion The serotypes of non-O157 STEC in animal feces O157 STEC were dispersed, and the resistant rate to common antibiotic was high. MLST typing results presents obvious polymorphism. Surveillance and manage ment of these strains should be strengthened.

OBJECTIVETo investigate the correlation between the status of sialic acid (SA) during perinatal period and early intelligence development of healthy full term infant, and to explore the effect of SA on the early intelligence development.

METHODA total of 127 pairs of healthy mothers-neonates in the Affiliated Hospital of Nantong University were recruited randomly in this prospective cohort study. The levels of SA from body fluids of mothers-neonates were measured by enzyme-linked immunosorbent assay, such as the full-term maternal and cord blood and the colostrum. The questionnaire surveys were carried out in mothers and mental development evaluation according to Children's Development Center of China (CDCC) were carried out in infants 3 to 4 months of age to obtain the mental development index (MDI) and psycho-motor development index (PDI).

RESULTA total of 120 pairs of maternal-neonatal subjects with complete data were included into statistical analysis. The levels of SA of maternal and cord blood and colostrum were (2.25 ± 0.02), (1.21 ± 0.01), and (5.01 ± 0.06) mmol/L respectively. MDI and PDI of infants 3 to 4 months of age were (99.40 ± 1.87) and (98.53 ± 1.96). The analysis using multiple linear regression indicated that MDI was associated with SA levels of cord blood and colostrum (β = 0.636, 0.175, P < 0.05), and PDI was also associated with them (β = 0.502, 0.262, P < 0.05). The levels of SA of cord blood and colostrums were individually divided into high-level group and low-level one according to the median level. MDI and PDI in high-level group of cord blood were both significantly higher than that in low-level group (111.85 ± 2.79) vs. (108.88 ± 2.0) , (101.08 ± 4.44) vs. (98.88 ± 2.0) P < 0.01. So were MDI and PDI in high-level group of colostrum compared with those in low-level group (111.71 ± 3.07) vs. (108.81 ± 1.56), P < 0.01; (101.29 ± 4.23) vs.(98.56 ± 1.79), P < 0.05. The analysis on correlation between the levels of maternal-neonatal body fluids showed that the level of SA of colostrum was positively correlated with that of cord blood (r = 0.507, P = 0.004). However, no correlation was found either between the level of SA of maternal and cord blood or between the level of SA of maternal blood and colostrums. Further division into high-level and low-level groups was done according to the median level of maternal blood. The levels of SA of colostrum and cord blood in high-level group were markedly higher than those in low-level one (5.12 ± 0.35) vs. (4.87 ± 0.22) and (1.21 ± 0.02) vs. (1.17 ± 0.01), P < 0.05.

CONCLUSIONHigh levels of SA of cord blood and colostrums might be beneficial to the early intelligence development of full term infant. Abundant intake of SA during perinatal period and good function of placenta may play important role in early intelligence development.
