The self-book renewing information in medical library was classified, which showed that the 3 months in a year and the period in a day with the largest number of readers who visited the medical library Website were characterized by their rigid need. In addition, the evidence was provided for the issuing time of information on li-brary information issuing platform in order to optimize the popularizing effect of library.

Objective To compare bispectral index (BIS) with narcotrend index (NI) during propofol-remifentanil anesthesia administered by target-controlled infusion (TCI).Methods Ten ASA Ⅰ or Ⅱ pafients aged 18-56 yr weighing 52-67kg undergoing abdominal surgery lasting>1h were included in this study.BIS and NI were monitored simultaneously.Anesthesia was induced with TCI of propofol with target plasma concentration (Cp) of 3～4μg/ml and remifentanil (Cp 3-4ng/ml).Tracheal intubation was facilitated with cis-atracurium 0.3 mg/kg.The patients were mechanically ventilated.PETCO2 was maintained between 30-35 mm Hg.Anesthesia was maintained with TCI of propofol and remifentanil by the anesthesiologist bhnded to BIS and NI values.according to hemedynamic parameters.BIS and narcotrend values were recorded every minute and compared by another anesthesiologist.All data were compared by Bland-Altman analysis and with Kappa coefficient for agreement.The correlation between BIS and NI was tested by Spearman correlation analysis.The number of error ofjudgement (Type Ⅰ was defined as BIS<40 and NI>62;Type Ⅱ was defined as BIS>60 and NI<20)Was counted.Results The correlation and agreement between BIS and NI during maintenance of propofol-remifentanil anesthesia administered by TCI showed good consistency.Conclusion Both NI and BIS Can help anesthesiologist control the depth of anesthesia during TCI of propofol-remifentanil.

Objective To explore clinic manifestations and laboratory investgation of virus encephalopathy.Methods The clinical course,cerebrospinal fluid(CSF),hepatic dysfunction,computerized tomography of 7 cases treated in our hospital from October 1999 to March 2005 were retrospectively reviewed.Results Seven cases of virus encephalopathy were typically associated with a suddent onset of high fever,severe convulsion,rapidly progressive coma,marked elevations of alanine aminotransferase(AST) and aspartate transaminase(ALT).Four cases died,3 cases had severe sequelae.Blood ammonemia was normal,brain CT scans revealed peripheral or basal nuclei low-density areas.Conclusion Children with a sudden onset of high fever,severe convulsions,rapidly progressive coma may have a poor prognosis.

Objective To further understand the effect of anti-fluoride water on intellectual development of children and dental fluorosis in drinking water-type of endemic fluorosis area Pucheng county Shaanxi province.Methods Two hundred 8 to 12 years old children were randomly selected in endemic fluorosis area with changed water or unchanged water, in 2009 in Pucheng county Shaanxi province. Intelligence quotient(IQ) of children was measured by Raven's test. Children's dental fluorosis was examined by Dean's classification scheme. Results The rates of child dental fluorosis in changed water and unchanged water endemic fluorosis areas were 28.50%(57/200), 87.88%(203/231) , respectively, the difference was statistically significant(x2 = 159.19, P＜ 0.01),while dental fluorosis indices were 0.57,1.97, was marginal, moderate epidemic. Children with IQ above 90 was accounted for 89.5% (179/200), 91.5% (183/200) in changed water and unchanged water endemic fluorosis area,respectively, the difference was not significant (x2 = 0.46, P ＞ 0.05). Conclusions Changed water may decrease the incidence of child dental fluorosis, but has no obvious effect on children's IQ development in endemic fluorosis area.

Objective To investigate the influence of β-lactam antimicrobial drugs on infants′intestinal flora.Methods Infants from 0 to 1 years old were enrolled in the study,who′s feces samples were tested for Bacillus bifidus,lactobacillus,enterococcus and E.coli by using 16S rRNA quantitative PCR technique before using antibiotics,on the third and fifth day duringβ-lactam antibiotics treatment and the seventh day after treatment.Results The numbers of Bacillus bifidus,lactobacillus,E.coli and enterococci detec-ted in usingβ-lactam antibiotics group were not statistically different from those in not using antibiotics group(P >0.05).The num-bers of Bacillus bifidus and lactobacillus increased with the treatment process,the differencies was statistically significant(P <0.05).The recovery of the numbers of intestinal Bacillus bifidus and lactobacillus in not using antibiotics group was significantly faster than using antibiotics group,the difference was statistically significant(P <0.05).Conclusion β-lactam antibiotics have gen-eral killing effect on the intestinal flora in infants,which could recover to normal.The recovery of intestinal flora could be delayed if antibiotics are used,however,reasonable antibiotics treatment would be very helpful in the treatment of primary diseases.

Objective To investigate the role and significance of miRNA-21 in the pathogenesis and development of inflammatory bowel disease (IBD).Methods The expressions of microRNA-21 (miRNA-21) in colonic mucosa and peripheral blood CD4+T cells were analyzed by fluorescence quantitative polymerase chain reaction (PCR) in 26 patients with active Crohn's disease (CD), 23 patients with active ulcerative colitis (UC) and 19 healthy controls.The relative expression amount of miRNA-21 in colonic mucosal and peripheral blood CD4+ T cells in 11 patients with CD was compared before and after infliximab (IFX) treatment, and its correlation with tumor necrosis factor (TNF)-α was analyzed.t-test was performed for comparison between groups.The correlation between miRNA-21 expression in peripheral blood CD4+ T cells and serum TNF-α was analyzed by Spearman correlation analysis.Results The expression of miRNA-21 in colonic mucosa of CD patients and UC patients was 4.720 ± 0.397 and 4.993±-0.415, respectively, which were both higher than that of healthy control group (1.101±-0.284),and the differences were statistically significant (t =7.657 and 8.356, both P＜0.01).The expression of miRNA-21 in peripheral blood CD4+ T cells of CD patients and UC patients was 3.254 ± 0.323 and 3.450±0.311, which were both higher than that of healthy control group (0.891 ±0.220), and the differences were statistically significant (t=6.007 and 7.098, both P＜0.01).After 12 weeks of IFX treatment, simple endoscopic score for Crohn's disease (SES-CD) of CD patients was 8.019 ± 0.349,which was lower than that before treatment (21.502 ± 1.185), and the difference was statistically significant (t=10.910, P＜0.01).The serum TNF-α level was 61.570±6.252, which was lower than that before treatment (173.500 ± 12.670), and the difference was statistically significant (t=7.926, P＜0.01).The results of correlation analysis indicated that serum TNF-α level was positively correlated with miRNA-21 expression in peripheral blood CD4+ T cells (r =0.780 4, P ＜ 0.01).Conclusions The increasing of miRNA-21 expression in IBD was closely correlated with the serum TNF-α level and severity of inflammation.miRNA-21 might be a new target for IBD treatment.
