OBJECTIVE: To investigate the influence of budesonide on animal model of minimal persistent inflammation (MPI) of allergic rhinitis in rats and to investigate the changes of interleukin-12 (IL-12) in nasal mucosa. METHOD: Sixty Sprague-Dawley (SD) rats were randomly divided into four groups: group A (allergic rhinitis group), B (experimental group), C (MPI model group) and D (bland group) respectively, with fifteen animals in each group. Rats from group A,B and C were sensitized intraperitoneally by injection of suspension of ovalbumin (OVA) and aluminum hydroxide in 0.9% physiological saline. Then, repeated local booster sensitization with different concentration of OVA suspension (1% and 0.01%) or physiological saline into the nasal cavity of those rats were performed. For group D, physiological saline was used only. From 36th day, group B were given budesonide treatment for three weeks. A, C and D group were given normal saline nasal spray. Symptoms (sneezing) of rats after antigen challenge were observed and the infiltration of eosinophils (EOS) together with the expression of intercellular adhesion molecule 1 (ICAM-1) and IL-12 in the nasal epithelial cells were also examined. RESULT: When challenged with 1% OVA, the sneezing number of rats in group B was increased markedly than that in group D (P < 0.05). However, there was no difference between group B, A and C (P > 0.05). When challenged with 0.01% OVA and given budesonide, the symptom of sneezing almost disappeared in group B just like that in group D and there was no difference between the two groups (P > 0.05). Besides, there was still more EOS infiltrated in the nasal mucosa of rats in group C than that in group D (P < 0.05). There was no expression of ICAM-1 in nasal epithelium of rats in group D, nevertheless, ICAM-1 was found mildly expressed in group C. IL-12 expression was significantly increased compared with group A and group C, and was no significantly difference compared with bland group (P > 0.05). CONCLUSION Budesonide significantly inhibited the late reaction of animal model of minimal persistent inflammation (MPI) of allergic rhinitis in rats and increase the expression of IL-12 in MPI model.

OBJECTIVE: To explore the prophylactic effect of Budesonide on the expression of IL-4,IL-5 in nasal mucosa in model of minimal persistent inflammation of allergic rhinitis in rats. METHOD: Eighty SD rats were randomly divided into allergic rhinitis group (A group), experimental (B group), control group (C group) and negative control group (D group). A group was made for model of allergic rhinitis. B and C group were made for model of the lightest persistent inflammatory response. After the models were established, half of rats in the A group, B group, C group and D group were executed, and EOS infiltration and the expression of IL-4, IL-5, ICAM-1 were observed in nasal mucosa. The remaining rats of B group were given budesonide (64 microg/side/time, twice/day) treatment for 2 weeks. A, C, D group were given nasal spray with normal saline for 2 weeks. After that A, B, and C groups were stimulated with 1% OVA daily for one week, D group were given nasal spray with normal saline. All rats were executed after excitation, EOS infiltration and IL-4, IL-5 expression were observed. RESULT: After the drug treatment, B group only had a small amount of mucous EOS infiltration and had no significant difference with D group, but in A and C group EOS had heavy infiltration. Gray value of the IL-4 positive areas in B group were significantly different compared with A and C group (P < 0.05), A group and C group had no significant difference (P > 0.05). Distribution of IL-5 positive signals was similar with that of IL-4. CONCLUSION Budesonide MPI application could significantly inhibit the allergic.

Applying scientific literature in the teaching of nutrition and food hygiene is neces-sary. It can not only deepen students' understanding of the course and improve students' English level and scientific research ability, but also can improve teachers' professional skill. To improve the effi-ciency of teaching, teachers should choose literature close to the course and pay attention to selecting review literature and English literature. Textbook should be principal line of study during the teach-ing. Teachers should control the number and timing of explaining literature and grasp the complexity of literature. In order to facilitate students' understanding, teachers should make full use of related figures and tables.

Objective: The aim of this paper is to identify the basic organizational structure and the key elements of integrated healthcare model of patients with Chronic Obstructive Pulmonary Disease (COPD) and propose an appropriate development strategy.Methods: Based on the literature review of research articles about integrated care on patients with COPD, an analysis was conducted with the help of the Chronic Care Model (CCM) which is a chronic disease management model.Results: From of a total 16 articles about 13 case studies were found.An integrated healthcare of COPD was carried out in 10 hospital-based or community-based care programs.Most of the patients were the elderly and health status were moderately severe or more severe.The components of healthcare programs varied from 4 to 12 included at least two CCM dimension.A coordinator or a case manager was appointed in all healthcare programs and a follow-up plan was made as well.Decision making was supported by clinic guideline and specialist resource in 9 integrated healthcare programs which community facilities involved.All programs included self-management with health education and individualized behavioral support was in 10 programs.The action plan was applied in 8 studies.8 studies using a clinical information system connected health care provider and patients.Conclusions: COPD integrated care program can be constructed according to the management model of chronic disease, and it is suggested that we can organize the COPD integrated care program based on CCM and the program comprises 4 organizational components of at least two CCM dimensions.The key elements of COPD integrated healthcare are to appoint a coordinator, to make a follow-up plan, and the necessity of community participation to support decision making, support self-management by education and individualized behavioral management with an action plan.

Objective To assess the value of ultrasound examination in transvaginal diagnosis of normal fetal heart with 11-14 weeks of gestation.Methods Totally 158 cases of normal fetal heart with high risk pregnancy and nuchal translucency thickness were examined by two ultrasoud approaches:transvaginal(TVS) and tranabdomina(TAS) in 11-14 weeks of gestation.Results The group of TVS was obviously clearer than TAS by displaying the normal fetal cardiac structural in 12 week of gestation and 13-14 weeks of gestation with significant difference between the two groups (P<0.05),respectively.No significant difference between the two groups in 11 week of gestation was observed.Conclusion The transvaginal echocardiogram is of clinical value in the high risk gravida during the late first and the early second trimester.

Objective To observe the short-term curative effect and safety of recombinant human erythropoietin(rHu-EPO)on patients with primary brain stem injury. Methods Sixty patients with primary brain stem injury were recruited at Liaocheng People' Hospital from July 2010 to July 2013. All cases were randomly divided into EPO group and control group. The patients in EPO group were injected subcutaneous with rHu-EPO five times at dose of 6 000 U,while patients in the control group were treated with placebo in 2 weeks. All other conventional treatments were the same. NIHSS score and GOS score were evaluated in two weeks and three months respectively. Moreover,blood pressure and hemoglobin were also measured. Results NIHSS score in EPO group was 11. 37 ± 7. 78,significant higher than that of control group after two weeks(19. 41 ± 8. 26,P = 0. 019). GOS score in EPO group was also significant differences in two groups after three months (Z = - 2. 367,P = 0. 009 ). However,no significant difference was observed in the followed-up blood tests. Conclusion Recombinant human erythropoietin could be the exact nerve protective effect,and might be an effective therapy for patients with primary brain stem injury.

Objective To observe influence of continuous lumbar cistern drainage on levels of amyloid β-peptide (Aβ) subtype (Aβ1-42) in cerebrospinal fluid and plasma in patients with diffuse axonal injury (DAI) and investigate its clinical significance.Methods Eighty-one DAI patients were enrolled and randomized into treatment group (42 cases) and control group (39 cases).Patients in control group received simple conventional therapy,while the patients in treatment group received not only conventional therapy but 14 days of continuous lumbar cistern drainage.Levels of Aβ1-42 in cerebrospinal fluid and plasma were detected by ELISA assay before therapy and at 1,5,9,and 14 days after therapy.Prognosis was assessed using GOS at 6 months after therapy.Results Levels of Aβ1-42 in cerebrospinal fluid and plasma showed a decrease in the first place and a gradual decrease afterwards in both groups,but a bigger and earlier drop of Aβ1-42 levels was observed in treatment group.Two groups showed significant difference of Aβ1-42 levels at day 14 (P ＜ 0.05).At 6 months after therapy,GOS score between treatment and control groups was (4.1 ± O.5) and (3.4 ± 0.3) points respectively (P ＜0.05).Conclusion Continuous lumbar cistern drainage improves the prognosis of DAI and this may relates to the decrease of Aβ1-42 levels in cerebrospinal fluid and plasma.

Objective:To explore the correlation among childhood trauma, obsessive-compulsive symptoms, and implicit and explicit memory in patients with obsessive-compulsive disorder(OCD).Methods:Fifty-two OCD patients were enrolled, and the childhood trauma was investigated by using the childhood trauma questionnaire short-form(CTQ-SF). The degree of obsessive-compulsive symptoms was assessed by using the Yale-Brown obsessive symptoms scale (Y-BOCS). In addition, the abilities of implicit memory and explicit memory were tested by vocabulary perception speed tasks and vocabulary recognition tasks.According to the scores of CTQ-SF, the patients were divided into abuse group( n=26) and neglect group( n=26). SPSS 22.0 software was used for t-test and Pearson correlation analysis. Results:Results of obsessive-compulsive symptoms, implicit memory, and explicit memory showed no differences between the abuse group and the neglect group( t=-1.959-1.839, P>0.05). The scores of obsessions symptoms(12.52±4.61) were positively correlated with the total scores of CTQ-SF (40.10±10.20)( r=0.331, P<0.05). On the subscale, the scores of obsessions were positively correlated with the scores of physical abuse(7.89±3.02), sexual abuse(6.47±2.28)( r=0.373, P<0.01, r=0.356, P<0.05). There was a negative correlation between the scores of physical abuse and the accuracy of explicit memory(68.75±13.33)( r=-0.281, P<0.05). The scores of physical neglect(8.98±2.67) was positively correlated with implicit memory response time(4 285.94±2 067.42)( r=0.314, P<0.05). Conclusion:Obsessions in patients with OCD are related to traumatic childhood experiences, especially physical abuse and sexual abuse.Physical trauma may influence the level of implicit and explicit memory in patients with OCD.

OBJECTIVETo assess the therapeutic effect of ozone therapy combined with sulfasalazine sulfasalazine delivered via a colon therapy system in the treatment of distal ulcerative colitis.

METHODSThis prospective randomized controlled clinical trial involved 54 patients with mild to moderate active distal ulcerative colitis, who were randomize into 3 groups in accordance with the inclusion criteria (n=18). Each group was given sulfasalazine at the daily dose of 2 g, and in colon therapy group and ozone therapy plus sulfasalazine therapy group, sulfasalazine was delivered via a colon therapy system on a daily basis; the control group received sulfasalazine via retention enema only. At 0, 2, and 4 weeks of the treatment, colonoscopy was performed to evaluate the disease activity, and biopsy samples were obtained at 0 and 4 weeks for histological examination.

RESULTSIn comparison with colon therapy group and control group, ozone therapy plus colon therapy resulted in more rapid alleviation of the clinical symptoms and better histological improvement without any adverse effects.

CONCLUSIONOzone therapy combined with sulfasalazine delivered via a colon therapy system is feasible and effective for treatment of ulcerative colitis.
