Objective In order to improve the diagnostic level of Crohn's disease( CD),the relevant literatures with CD in China were reviewed and the causes of misdiagnosis about CD were analyzed. Methods Papers on CD published in medical journals from 1989 to 2003 in CMCC and VIP are collected and reviewed one by one, and then the characteristics of the misdiagnosed and missed CD were recorded and the causes of these cases were analyzed. Results From 1989 to 2003, there are 428 papers about CD, of which 261 papers are about clinical studies(60.9%); In these papers, total of 3397 CD cases were reported. In these cases there are 2357 cases missed, clinical symptoms are various and complex including abdomen pain (62.5%),diarrhea(51.5%), abdomenal lumps(16.6%) and so on. The most commonly involved sites of CD are terminal ileum (62.5%), colon (26.9%) and ileum combining with colon (38.9%). Cranulomas were identified in 61.2% of operative specimens and in 27.6% of biopsy specimens. The most common missed diagnosed diseases are intestinal tuberculosis(32. 2% ), simplex intestinal block (23.2%) and intestinal block caused by tumor(6.4%) and acute appenditis(27. 9% ). There are 389 cases misdiagnosed as CD, the most common diseases are tuberculosis(53.5%), small intestinal lymphoma(14.4%) and colonal cancer (17.0%). Conclusion Papers on CD are increased gradually during the periods from 1989 to 2003 with rather high missed or misdiagnosis. As a result, it is necessary for us to improve the cognitzability on CD and to improve the accuracy of diagnosis.

Objective The purpose of this study was to evaluate the disinfection effectiveness and properties of acrylic resin via microwave irradiation. Methods Forty acrylic resin base dentures fabricated in a standardized procedure were chosen and divided into Group A,B,C and D randomly. Group A,B and C were immersed in 200ml distilled water and submitted to microwave irradiation at 700W for 3,4,5 minutes individually. Group D was used as positive control. Bacteria specimens from each group were got for culture and numbers were calculated. Then the four groups were tested for the flexural strength and impact strength by universal test machine before and after microwave irradiation sterilization. Results The germicidal ratio of Group B was more than 90% ,while the ratio of group C was 100%. There was no significant difference in flexural strength and impact strength between group C and group D. Conclusions Microwave irradiation for 5 minutes at 700W produced sterilization of dentures contaminated with all bacteria whereas the denture strength is not affected. Microwave irradiation at 700W solution for 5 minutes was effective to sterilize acrylic resin base dentures.

To develop a safe and effective new generation vaccine for IRKV-THChina12 prevention, we constructed a non-replicative recombinant human adenovirus carrying the IRKV-THChina12 G gene, named as rAd5-IRKV-G. The IRKV-THChina12 G protein expressed by the recombinant human adenovirus in 293AD cells was detected by western blot and indirect immunofluorescence test. To evaluate the immunogenicity of the recombinant, mice were immunized with rAd5-IRKV-G by intramuscular (i. m.) or intraperitoneal (i. p.) route and with non-exogenous gene expressing wild type adenovirus wt-rAd5 as a control. Results showed that the rAd5-IRKV-G could induce continuous and statistically significant (P ≤ 0.05) anti-IRKV neutralizing antibody (NA) production in immunized mice by i. m. or i. p. route. In particular, no significant difference (P > 0.05) of the NA titers between the two administration routes were observed, that provides an alternative choice for animal immunization method in the future application.

Objective:To explore the risk factors and the treatment outcomes of rifampicin-resistant tuberculosis (RR-TB) in Guizhou Province.Methods:The clinical data of 16 548 pulmonary tuberculosis patients with drug sensitivity test results registered in the Tuberculosis Information Management System in China from designated tuberculosis hospitals of 88 counties (cities, districts) in Guizhou Province from January 2014 to December 2018 were collected. The gender, age, occupation, ethnicity, patient registration classification, molecular biology or Lowenstein-Jenden (L-J) solid culture results of positive sputum culture patients, and treatment outcomes were retrospectively analyzed. Cohen′s kappa coefficient was used to analyze the consistency between molecular biology and L-J solid culture in detecting rifampin resistance. Chi-square test and non-conditional logistic regression model were used to analyze the risk factors of mono-rifampicin resistance tuberculosis and multidrug-resistant tuberculosis (MDR-TB) and the factors affecting treatment outcomes.The measurement data were compared by chi-square test or Fisher exact test. Results:The detection rate of RR-TB in the newly diagnosed cases was 6.79%(807/11 883), and that in the retreated cases was 30.01%(1 400/4 665). The drug sensitivity tests of 184 sputum culture positive RR-TB samples were performed by both L-J solid culture and molecular biology, and the rifampicin resistance detection rates were 20.65%(38/184) and 16.85%(31/184), respectively. The consistency between two methods was good ( kappa=0.697, 95% confidence interval ( CI) 0.564-0.830, P<0.01). Multivariate logistic regression analysis showed that patients aged 20 to 39 years old (odds ratio ( OR)=1.679, 95% CI 1.134-2.487) and aged 40 to 60 years old ( OR=1.526, 95% CI 1.019-2.283) were the high risk groups for MDR-TB. Treatment failure ( OR=27.753, 95% CI 22.455-34.300; OR=2.982, 95% CI 1.544-5.760, respectively), relapse and return ( OR=5.381, 95% CI 4.563-6.346; OR=3.897, 95% CI 2.901-5.234, respectively) were both high risk factors for MDR-TB and mono-rifampicin resistance tuberculosis. The treatment rate of RR-TB patients was 39.96% (396/991) from 2014 to 2016. Among 396 treatment cases, 138(34.85%) were cured and 16(4.04%) died. The patients aged>60 years old had lower cure rate (12.68%(9/71) vs 39.69%(129/325)) and higher death rate (11.27%(8/71) vs 2.46%(8/325)) than those aged ≤60 years. The differences were both statistically significant ( χ2=18.732, P<0.01; Fisher′s exact test, P=0.003). Conclusions:The RR-TB patients in Guizhou Province are mainly re-treated. Young and middle-age (20-60 years old) and treatment history are risk factors for RR-TB. The patients over 60 years old have a low cure rate and a high mortality rate. It is suggested to strengthen the screening, treatment and management of RR-TB to reduce the spread of tuberculosis.
