Objective To investigate the clinical application value of fluorescence PCR in vitro diagnosis(IVD)reagent kits in the HLA-B27 detection by comparing 2 kinds of HLA-B27 IVD reagent kit approved by CFDA.Methods A total of 573 clinical blood samples were collected and detected for HLA-B27 by the approved reagent kits based on the fluorescence PCR technique and the flow cytometry.The samples with inconsistent testing results by the two kits were further confirmed by the PCR sequencing.At the same time,about 5% samples of the positive results detected by the fluorescence PCR method were extracted for conducting the re-testing.Results Among 573 samples,191 samples were HLA-B27 positive and 382 cases were HLA-B27 negative by flow cytome-try;the same samples had 194 cases of HLA-B27 positive and 379 cases of HLA-B27 negative by real-time PCR.With flow cytome-try as reference of the final results,the positive coincidence rate of the two kinds of kit was 96.33%(184/191),the negative coinci-dence rate was 94.76%(362/382),27 samples had inconsistent results from the two kinds of assay(accounting for 4.71% of the to-tal number of samples),the total coincidence rate was 95.29% [(184+362)/573],the Kappa value was 0.896(P =0.02);the chi-square test P =0.021,the two kinds of testing method had the high consistency,but the differences existed in the testing results. The re-testing results by PCR sequencing(including 27 samples with inconsistent results by two kinds of kit)were entirely consist-ent with the fluorescence PCR testing results.Conclusion Compared with the authority method flow cytometry for HLA-B27 tes-ting in clinic,the fluorescence PCR kit may present more accurate judging ability for the HLA-B27 testing on the basis of ensuring the higher consistency of the testing results,is easier compared with the sample preparation and operating procedures,and has the stronger clinical application value and prospects s.

Objective To observe the clinical Resultsof ambroxol combined with glucocorticoids in the treatment of otitis media with effusion.Methods 81 cases fron June 2015 to 2016 October, were randomly, double-blind principle divided into observation group(42cases)and control group(39cases).The control group glucocorticoid therapy observation group were treated with ambroxol combined with glucocorticoid treatment, pure tone was observed before and after treatment were compared listen valve measured air conduction hearing level, hearing recovery and clinical efficacy.ResultsThe observation group were pure tone hearing valve after treatment was measured air conduction hearing level was significantly higher (P<0.05);drum pipe tobacco functioning proportion of patients in the observation group after treatment was 85.71%, significantly higher than 48.72% (P<0.05);The observation group total effective rate was 92.86%, significantly higher than 74.36% (P<0.05).Conclusion Ambroxol combined with glucocorticoids be effective in treating secretory otitis media, otitis media with effusion improve the clinical efficacy, and easy to operate, and is worthy of clinical application.

Objective To investigate the relationship between the cell cycle blocked by hyperthermia and the expression of rhythm gene Bmall in gastric cancer MKN28 cells so as to provide the academic evidence in hyperthermia therapy for gastric cancer.MethodsThe MKN28 cells were resuscitated and cultured in vitro.In control group MKN28 cells were cultivated at 37 ℃.In experimental groups MKN28 cells were heated at 43 ℃ for different durations.The cell morphology was observed by microscopy.Methylthiazdyl tetrazolium (MTT) assay was adopted to evaluate the inhibitory effect of the cell line.The flow-cytometry was adopted to observe the influence on the cell cycle.The Bmall mRNA expression was investigated by real-time quantitative reverse transcription-polymerase chain reaction ( RT-PCR).ResultsThe remarkable changes of cell morphology were observed by microscopy after exposure to heating.According to the data of MTT assay,37 ℃ heating could not inhibit the proliferation of MKN28.The inhibitive rates of cell growth after 0.5 h,1 h,l.5 h at 43 ℃ was (21.76±5.46)％,(25.30 ±4.36)％ and (27.62 ± 3.78 )％,respectively.Results from flow-cytometry showed that G0/G1 phase cells in lh at 43 ℃ were remarkably less than those in the control group.However G2/M cells were significantly more than those in the control group.The mRNA expression of Bmall was the lowest when heating lh at 43 ℃ as compared to the control group.ConclusionsHyperthermia could induced the cell cycle changes and the expression of Bma11 in gastric cancer MKN28 cells.

Objective To investigate the difference between the self-evaluation of patients with dental and facial esthetics in skeletal malocclusion and normal persons.Methods The subjects were divided into three groups:62 patients with skeletal Class Ⅱ,84 patients with skeletal Class Ⅲ,as well as 130 persons in control group.There was no obvious difference in gender and age among the three groups.Happiness with dental and facial appearance was assessed using questionnaires.Analysis of variance,linear regression and logistic regression were used for statistical analysis.Results Skeletal malocclusion patients were less happy with their dental appearance than control group.Class Ⅱ patients and women had lower happiness scores for their dental appearance.Among skeletal malocclusion patients,the shape (44.5 ％) and prominence of their teeth (17.8 ％) were the most frequent causes of concern.Older subjects,women,and skeletal malocclusion patients were less happy with their facial appearance.Most of them were dissatisfied with the facial appearance focused on the chin (53 ％),facial contours (37 ％),and the position of the teeth when smiling (33 ％).A greater proportion of Class Ⅲ subjects than Class Ⅱ subjects wished to change their appearance.Conclusions The findings indicate that women and skeletal malocclusion patients have lower levels of happiness with their dentofacial appearance.Although Class Ⅱ patients exhibit the lowest levels of happiness with their dental appearance,there is some evidence that concerns and awareness about their facial profile are more pronounced among the Class Ⅲ patients.

Immune system is a security guard to help human body repel or remove bacteria, viruses, parasites and other fore-ign invaders .But when some tissue components or the immune system itself become abnormal, it can not distinguish friend from foe accurately and may attack our own tissue then cause some clinical symptoms, leading to autoimmune diseases. Nearly 5 % of the world's population suffer from various autoimmune diseases. By now in addition to control the formation of autoantigens such as infection,tiredness, the main biologics used in clinic are immunoregulators to block pathological autoimmune response and then to create a new proper immune response. Recently, new biologics to treat autoimmune disease come into being one after another, and this article gives a brief overview about research progress in anti-autoimmune disease biologics.
