Objective To study the occurrence of the extraintestinal manifestations of inflammatory bowal disease.Methods By the retrospective study,the data of 201 IBD patients was analysed.Results A total of 21.43%of patients with ulcerative colitis(UC) and 15.79% of patients with Crohn's disease(CD) showed at least one kind of EMIs.In UC patients with EIM,the activity of disease was active phase in 89.74% and remassion phase in 10.26%.Tree CD patients were all in active phase. Musculoskeletal manifestation was the most frequent EIM,the second was dermatological manifestation,EIMs involving the genitourinary、thyroid、hepatobiliary were rarely. EN and/or PG and arthritis were more frequent coexisting other EIMs.Conclusion The prevalence of EIM was not rarely.EIM was most common among female and young patients.Arthritis and dermatological manifestations were most frequent of all assessed.The patient could have multiple EIMs and there was a tendency that EIM was more likely among patients in active phase、severe severity and with pancolitis.

Autoimmune encephalitis is a group of inflammatory diseases related to autoantibodies that affect the central nervous system. Early diagnosis of patients with autoimmune encephalitis has certain difficulties, because the clinical manifestations caused by different types of autoantibodies can be non-specific, and the presence of multiple autoantibodies can cause variation and superposition of clinical manifestations. The article reported a case of autoimmune encephalitis patients with double positive anti-N-methyl-D-aspartate receptor and dipeptidyl-peptidase-like protein-6 antibodies, and reviewed relevant literature for clinical reference.

OBJECTIVE: To study the role of nuclear factor-kappa B (NF-kappaB) and cycloxygenase-2 (COX-2) in the onset of phlegm obstruction due to lung-deficiency in rats and the therapeutic mechanism of Huatan Recipe. METHODS: Twenty-four SD rats were randomly divided into normal group, model group and treatment group, with 8 rats in each group. The rats in the model group and treatment group were exposed to sulfur dioxide and cold wind to establish the rat model of phlegm obstruction due to lung-deficiency, and the rats in the treatment group were also treated with Huatan Recipe, a compound traditional Chinese medicine. The expression of NF-kappaB in the bronchial epithelial cells of the rats was tested with the method of immunohistochemistry, and the COX-2 mRNA in the lung tissues of the rats was measured by using reverse transcription-polymerase chain reaction. RESULTS: The expressions of NF-kappaB and COX-2 mRNA in rats of the model group were higher than those of the normal group (P<0.01), and the expressions of NF-kappaB and COX-2 mRNA in rats of the treatment group were obviously lower than those of the model group (P<0.01). CONCLUSION: The NF-kappaB and COX-2 play an important role in the onset of phlegm obstruction in rats. Huatan Recipe may prevent the development of phlegm obstruction by down-regulating the expressions of NF-kappaB and COX-2 mRNA.

Objective:To investigate the relationship between mandibular second molar calcification stage and cervical vertebrae maturity.Methods:Samples were derived from panoramic radiographs and lateral cephalograms of 500 subjects (223 males and 277 females)aged 9 to 18 years.Demirjian Index(DI)and cervical vertebrae maturation indicators(CVMI)were used for the evaluation of dental and skeletal maturity.Results:A significantly association was found between DI and CVMI(P <0.001).DI stage E was associated with CVMI Ⅱ(pre-peak of pubertal growth spurt).DI stages F and G was associated with CVMI Ⅲ and Ⅳ(peak of pu-bertal growth spurt).DI stage H was associated with CVMI Ⅴ and Ⅵ(end of pubertal growth spurt).Conclusion:DI and CVMI are significantly associated.Mandibular second molar DI stage is a reliable indicator of skeletal maturity.

Objective To study the correlation with the infectious situation of Borna disease with the multiple sclerosisof Zunyi region. Methods Established method of the specific CIC and an antibody of Borna were used to detect the PBMC of 7cases of patients with multiple sclerosis and 93 cases of control group.Results In the collected 7 cases of PBMC in patients with multiple sclerosis, detected 2 positive samples of the specific CIC and antibody of Borna with a positive rate of 28.57%(2/7).Meanwhile, positive plasma samples were also detected in healthy control group, and the positive rate was 7.53%(7/93),The antibody positive rate of control group was also 5.38%(5/93).But between the two groups, the difference was no statistically significant.Conclusion Results indicate that the possibility of BDV infection is presented in Zunyi regions.BDV infection is not necessarily associated with multiple sclerosis.

Objective To investigate the protective effects and mechanisms of granulocyte-colony-stimulating factor (G-CSF)on a rabbit model of chronic myocardial ischemia.Methods Myocardial ischemia models were created by partial ligation of the left anterior descending coronary artery in Japanese white male rabbits.Rabbits were subcutaneously injected with G-CSF (G-CSF group)or saline (control group)for 6 days after myocardial ischemia.The percentage of CD34-positive cells in the peripheral blood was evaluated by flow cytometry,and CD34-positive cells homing and vWF expression in the ischemic myocardium were determined by immunohistochemistry.Results Rabbits in G-CSF group had a higher survival rate than those in control group (P <0.05).Immunohistochemistry of the ischemic myocardium showed that compared with control group,G-CSF group had increased homing of CD34-positive cells on day 7 post-surgery,and more vessels on day 28 post-surgery by anti-von Willebrand factor staining.In addition,we observed an increase in the percentage of CD34-positive cells in the peripheral blood in G-CSF group.Conclusion G-CSF produces an obvious protective effect against chronic myocardial ischemia in rabbits by increasing stem cell mobilization,homing to ischemic myocardium and accelerating neovascularization.

Objective To explore the appropriate frequency of ventilator tube replacement by researching the influence of different ventilator circuit change frequency on ventilator-associated pneumonia (VAP).Methods A prospective randomized sampling study was conducted.The patients undergoing invasive mechanical ventilation over or equal to 3 days admitted to emergency intensive care unit (EICU) of the First Affiliated Hospital of Kunming Medical University from December 2012 to December 2015 were enrolled.The patients were divided into 3,7 and 10 days group according to the frequency of ventilator tube replacement.Bacteriology of ventilator tube and the incidence of VAP were compared among the groups.Results Ninety-eight patients were enrolled,mainly with the artificial airway of endotracheal intubation or tracheotomy,with 56 male and 42 female,aging 8 to 86 years with mean of (51.97 ± 17.56) years.There were no statistical differences in gender,age,Glasgow coma scale (GCS) score,cough function and application of glucocorticoid,enteral nutrition,atomization and sedative therapy among three groups,indicating that the risk factors among three groups were consistent.The bacteria detection rates of extension tube,breathe out tube,breathe in tube,and hydrops collection cup were 36.7％,36.7％,33.3％,and 33.3％ respectively in 3 days group,and they were 73.0％,67.6％,62.2％,and 62.2％ in 7 days group respectively,and were all 90.3％ in 10 days group.It was showed that the bacteria detection rate in different pipe parts was almost the same with the same change frequency,and the rate was higher with the longer usage of ventilator tube (x2 values were 20.599,19.879,21.975,21.975,all P =0.000).The longer of the tube used time,the higher incidence of VAP.The incidence of VAP in 3,7,10 days groups were 26.7％,59.5％ and 77.4％,respectively,but there was statistically significant difference among all groups (x2 =30.486,P ＜ 0.001).Based on the value of 3 days group,the incidence of VAP in the 7 days group was 15.950 folds of 3 days group,and the incidence of VAP in the 10 days group was 18.333 folds of the 3 days group (both P ＜ 0.001).Conclusion This study suggests that the longer of pipeline using time,the more serious degree of bacterial contamination of pipeline,the higher incidence of VAP.
