The incidence of severe acute pancreatitis in children is lower.But it has abrupt onset and atypical symptoms.The fatality rate is relatively high.This paper will review the progress on the diagnosis and treatment of severe acute pancreatitis.

Objective To compare the effect of inhaled corticosteroids and montelukast in children with asthma .Methods Data were obtained from Pubmed ,Embase and Central databases ,CNKI and VIP .Only randomized controlled trials (RCT ) that evalua-ting inhaled corticosteroids and montelukast for children were included .The Cochrane collaboration risk bias tools was used to eval-uated the quality of literature .Results The patients with inhaled corticosteroids had a better effect in FEV 1% and PEF than pa-tients with montelukast ,the incidences of adverse drug reactions had no statistically significant difference .The patients with inhaled corticosteroids combined with montelukast had a better effect in FEV 1% or PEF than patients with inhaled corticosteroids only . Conclusion The effect of inhaled corticosteroids is better than montelukast ,the effect of inhaled corticosteroids combined with montelukast is better than inhaled corticosteroids only ,and has drug safety .

Objective To investigate the effect of fluoride on expression of Runx2 mRNA and protein in bone tissue of rats. Methods Fourteen SD rats were randomly divided into two groups: control group(tap water with fluoride ＜ 0.06 mg/L), and fluorosis group(fluoride 50 mg/L in water). After 4 moths, expressions of both mRNA and protein of Runx2 in rat bone tissue were determined by RT-PCR and Western blotting. Results The results showed that the expression of Runx2 mRNA and protein in fluoride-treated bone tissue were 2.287 ± 0.261 and 0.929 ± 0.229, respectively, both of which were significantly higher than those of control group(0.995 ± 0.123,0.317 ± 0.068, t = 11.85,6.78, P ＜ 0.05). Conclusions Fluoride can increase the expression of Runx2 mRNA and protein in bone tissue of rats, and Runx2 may be involved in the pathogenesis of bone injury caused by fluoride.

This study is to evaluate the HAART pharmacodynamics with dolutegravir as the "anchor" in vitro. A nucleoside reverse transcriptase inhibitors (NRTIs) resistant recombinant virus model (VSVG/HIV-1(RT-D67N,K70R,T215F)) and an integrase inhibitors (INIs) resistant recombinant virus model (VSVG/HIV-1(IN-G140S,QI48H)) were constructed and established. The anti-viral pharmacodynamics was evaluated with drug combinations including two NRTIs along with one INI or one NNRTI. The results showed that the combination with an INI gave a stronger synergism on wild type HIV-1 replication comparing to that with an NNRTI. Comparing the two INIs as the "anchor" for HAART, DTG exhibited an equivalent CI to that of RAL on wild type HIV-1 replication; but a greater synergy than RAL on INI-resistant HIV-1 replication. Besides of the pharmacodynamics results of DTG-based drug combination, the results may contribute to clinical antiviral therapy.

Objective To investigate the effect and its mechanism of cyclin dependent protein kinase inhibitor Olomoucine treatment on experimental herpes simplex encephalitis(HSE). Methods 45 mice were randomly assigned to HSV-1 sham-infected group (n=15), HSV-1 infected control group (n=15) and Olomoucine treated group (n=15). Flow cytometry was used to detect the expression of brain cells surface antigen CD11b. The reverse transcription polymerase chain reaction (RT-PCR) to detect the expression of tumor necrosis factor-? (TNF-?) and Interleukin-6 (IL-6). TUNEL method was adopted to detect neural cells apoptosis. Pathologic slices of brain tissues were used to identify tissue morphology differences. The survival rates were compared between the treatment groups Acyclovir (n=20) and Olomoucine (n=20) by the method of Kaplan-Meier 2 weeks after HSV-1 infection. Results After HSV-1 infection, the expression of brain tissue CD11b, TNF-?, IL-6 were significantly increased compared with sham-infected group (allP

OBJECTIVE To investigate the impact of disinfection quality in surgical dressing room on the healing of wound with dressing exchanges in order to implement procedures to prevent nosocomial infection. METHODS A retrospective investigation was performed and cases of poor surgical wound healing from Jan 2006 to Dec 2007 were collected and analised. Effective measures were taken to enhance the management and surveillance in the dressing room. RESULTS After taking the prevention procedure,the passing rate of disinfection was increased. Before implementing the prevention procedure the passing rates of air,surface and finger cultured were 83.3%,83.3% and 75.0%,respectively,After taking the prevention procedure the passing rates of above were all 100.0%.The rate of poor wound healing decreased from 4.16% to 1.59%. CONCLUSIONS The disinfection quality of dressing room has direct effects on the wound healing. The management of dressing room disinfection should be emphasized to cut down the nosocomial infections of wound.

Objective To investigate the changes of interleukin-17A(IL-17A)and interleukin-22(IL-22)in the lung of cigarette smoke exposed mice and the effect of smoking cessation and N -acetylcysteine (NAC )treatment . Methods BALB /c mice in experimental groups were exposed to cigarette smoke.Then the smoke-exposure was stopped and mice were treated with NAC gavage.The mice were executed 1,2,and 3 months after smoking cessa-tion.Lung tissue sample and bronchoalveolar lavage fluid(BALF)were collected.HE staining was used to observe the pathologic changes of the lung and ELISA was used to measure the level of IL-17A and IL-22.Results Con-siderable emphysematous changes was found in the lung of mice exposed to cigarette smoke.Compared with the controls,the level of IL-17A and IL-22 elevated remarkably in pulmonary tissue and BALF after smoking exposure and declined gradually after smoking cessation.Additional NAC gavage treatment enhanced the decline tendency. Conclusion IL-17A and IL-22 might play a complex role in the chronic inflammatory changes of lung in mice ex-posed to cigarette smoke.

Objective To research the effects of different titers of bacteriophage D29 on growth and function of airway epithelial cell 9HTE.Methods Cell viability rates was analyzed after applying high(109 PFU/mL)and low(107 PFU/mL)titers of bacteriophage D29 and phage buffer respectively by MTT colorimetry.Additionally,the secretion levels of IL-6,IL-8 in cell culture supernatant were detected by ELISA.RT-PCR was performed to detect the expression of ICAM-1 mRNA.Cell apoptosis rate was analyzed by flow cytometry.Results There was no difference in cell growth,secretion levels of IL-6,IL-8,ICAM-1 mRNA and cell apoptosis rate between cells treated with high and low titers of D29 and phage buffer(P>0.05).Conclusion Neither high nor low titer of bacteriophage D29 exerts effect on growth and function of airway epithelial cell 9HTE in vitro.
