In the course of follow-up analyses of visual field test,it should take more than two visual field tests that had similar results as baseline test,and some factors should be taken into account,such as accordant testing conditions,reliable indeces,test errors and fluctuation effects,and so on.The indeces of Mean Deviation(MD)and Pattern Standard Deviation(PSD)could reflect the whole change trend of follow-up visual field test,while sensitivity value of every point and their pattern deviations could help to analyse tiny changes of visual field tests.Those statistic softwares provided by automatic perimetry should be used adequately.Through the follow-up analyses of visual field test,glaucoma doctors could adjust therapy schemes in time in order to obtain objective intraocular pressure and stabilize visual field and glaucoma.

Objectives: To investigate the role of Xpert MTB/RIF assay for rapid diagnosis of osteoarticular tuberculosis.Methods: From February 2014 to November 2014,pus specimens of 49 osteoarticular tuberculosis patients and 32 nontuberculosis patients were detected by Xpert MTB/RIF system,and the sensitivity,specificity,positive predictive value,negative predictive value,agreement rate of Xpert MTB/RIF system were calculated,and clinical diagnosis was used as the reference standard.All the pus specimens were detected by acid-fast stain and fast culturing(BACTECT MGIT 960),to find the difference of sensitivity and specificity among Xpert MTB/RIF,acid-fast stain,and fast culturing.The role of Xpert MTB/RIF assay for rapid diagnosis of osteoarticular tuberculosis was evaluated through the two factors above.Results: It took 2.3±0.2h to detect each pus specimen by Xpert MTB/RIF.Among the 49 osteoarticular disease patients,46 were positive,3 were negative by Xpert MTB/RIF test.Among the 32 nontuberculosis patients,1 was positive,31 were negative by Xpert MTB/RIF test.The sensitivity,specificity,positive predictive value,negative predictive value,agreement rate was 93.87%,96.87%,97.87%,91.17%,95.06% respectively for Xpert MTB/RIF assay.Among the 46 specimens which were positive by Xpert MTB/RIF test,10 had rifampicin resistance mutation,with the rate of rifampicin resistance mutation as 21.73%.Among the 49 osteoarticular disease patients,8 were positive,41 were negative by acid-fast stain test,the sensitivity was 17.39%,and based on fast culturing test,11 were positive,38 were negative,the sensitivity was 23.91%.All pus specimens of 32 nontuberculosis patients were negative by acid-fast stain test and fast culturing test.As for the sensitivity,Xpert MTB/RIF was superior to acid-fast stain and fast cultureing (P＜0.05).While as for the specificity,there was no statistical difference among Xpert MTB/RIF,acid-fast stain,or fast culturing (P＞0.05).Conclusions: The role of Xpert MTB/RIF assay for rapid diagnosis of osteoarticular tuberculosis is perfect.It is of time saving,high sensitivity and high specificity,which is superior to the traditional methods.

Objective The anti tumor and anti metastasis effects of angiocytotoxic therapy (TNP 470/Gemcitabine) were investigated using a model of human pancreatic carcinoma by surgical orthotopic implantation (SOI). Methods The SOI model was developed by suturing small pieces of SW1990 tumors into the tail of pancreas in nude mice. Twenty four male mice were randomly divided into control group, G100 group receiving 100 mg/kg Gemcitabine intraperitoneally injection on days 0,3,6 and 9 after transplantation, and T30 group receiving 30 mg/kg TNP 470 subcutaneous injection on alternate days for 8 weeks. Another thirty two male mice were randomly divided into control group, T15 group, G50 group and combination group (TNP 470 30 mg/kg+ Gemcitabine 50 mg/kg). Animals were sacrificed ten weeks after transplantation. Results G100 group had a significant inhibitory effect on tumor growth of pancreatic carcinoma compared to T30 group, while the metastasis of tumor was significantly inhibited by T30 group compared to G100 group. Neither G100 group nor T30 group showed a significant improvement on survival rate. T15 group and G50 group alone had no significant inhibitory effect on the tumor growth and its metastasis. Mean while a significant anti tumor, anti metastatic effect and a significant improvement on the survival rate were observed in combination group. The inhibitory effect of G50 group was enhanced by 2 times with T30, and 2/8 of the tumors bearing animals were cured by the combination therapy. The level of microvessel density in T30 group was significantly lower than that in T15 group and control group ( P

Objective: To research the proteins differentially expressed during evolution of experimental colorectal carcinoma (normal mucosa→adenoma→carcinoma→liver metastasis) so as to find the early diagnostic biomarker of colorectal cancer as well as to understand its pathogenesis mechanism. Methods: Ninety male rats were injected with 1, 2-dimethylhydrazine intraperitoneally and sacrificed at different weeks to establish the experimental colorectal tumor models (from normal mucosa to liver metastasis). These samples at different stages were collected and divided into four groups (normal mucosa group, adenoma group, carcinoma group, and liver metastasis group). The proteins of these 4 groups were extracted to conduct 2-dimensional gel electrophoresis. The differential protein spots were examined by mass spectrometry and analyzed by bioinformatics. Results: Ten differentially expressed proteins were identified by 2-dimensional gel electrophoresis and mass spectrometry including α-enolase, cardiac α-actin (CA), transgelin protein, myosin regulatory light chain smooth muscle isoform (MRLC), glyceraldehydes-3-phosphate dehydrogenase (GAPDH), haptoglobin, disulfideisomerase (DI), creatine kinase mitochondrial (CKm), heat shock protein-8 (HSP-8) and Keratin complex-2 (KC-2). Conclusions: There exist differentially expressed proteins at various stages during the evolution of colorectal carcinoma. These proteins may be the candidate biomarkers for the early diagnosis of colorectal carcinoma. Proteomic technology is an effective way for preliminary identification of the tumor biomarkers.

Objective To consecutively investigate the quality of auto-antibody testing of the whole country and to improve quality.Methods A nation-wide investigation was carried out and hospitals or departments participating were notified by letter or telephone communication.Autoantibodies tested for quality control survey included anti-nuclear antibody (anti-ANA),anti-double-stranded DNA (anti-dsDNA)antibody,anti-extractable nuclear antigens (anti-ENA) antibody,anti-mitochondria antibody (AMA),anti-smooth muscle antibody (ASMA) and anti-citrulline antibody (anti-CCP).There were 15 samples in total for testing,including 3 control samples for each test.Same sample was used for both AMA and ASMA test.Sample distribution and data analysis were carried out double-blindly.A total of 114 hospitals or departments participated in the survey.Multiple testing methods were adopted including indirect immumo-fluo-rescence (IIF),immuno-blot (IB),dot-blot (DB),double immuno-diffusion (DID),enzyme linked immuno-sorbent assay (ELISA),chemiluminescent assay,dot-immunogold filtration assay.Results The accurate rates for this survey were 98％,96.6％,89.5％,98.1％,92.1％,96.4％ respectively for ANA,anti-dsDNA,anti-ENA,AMA,ASMA and anti-CCP.Anti-ENAs were further divided into anti-RNP,anti-Sm,anti-SSA,anti-SSB and anti-Scl-70 subgroups,and the accurate rates were 88.4％,96.8％,100％,100％ and 95.8％,respectively.Titers of ANA varied greatly among different labs,so did quantitative analysis of anti-CCP,AMA and antidsDNA by ELISA.However,the accuracy of ANA types determined by IIF was greatly improved.Detection rate of AMA and AMSAwas still low.Conclusion Among detected antibodies,ANA,anti-dsDNA and antiCCP are the most prominently improved.Accurate rate of anti-ENA antibody is slightly increased.

Objective To investigate the current national situation of autoantibody test in order to improve the quality of autoantibodies test.Methods Hospitals or departments in the whole country participated voluntarily or on invitation.Fifteen samples in total were distributed double-blindly,and autoantibodies including anti-nuclear antibody (ANA),anti-double-stranded DNA (anti-dsDNA) antibody,anti-extractable nuclear antigens (anti-ENA),anti-citrulline antibody (anti-CCP),anti-mitochondria antibody (AMA) and anti-smooth muscle antibody (ASMA) were tested in 6 samples.The samples were used for AMA and ASMA tests.Results A total of 148 hospitals or departments participated and multiple testing methods were adopted.The accurate rate of ANA(97.3％),AMA (96.1％),ASMA (92.1％) and anti-CCP (97.4％) were higher than that of anti-dsDNA (81.9％) and anti-ENA (77.2％).Anti-RNP and anti-Scl70 in anti-ENAs had the lower accurate rate,90.9％ and 80.3％ respectively.Taking data of the past 10 years together,the accuracy of antiSSA,anti-SSB,anti-Sm had been stable since 2009,while that of anti-RNP and anti-Scl70 decreased slightly.For methodology,indirect immunofluorescence was mainly adopted in the testing of ANA,anti-dsDNA,AMA and ASMA,immunoblotting was mainly adopted in anti-ENA detection and enzyme linked immunosorbent serologic assay was used for anti-CCP test.Conclusion No major variation of primary testing method is found in recent 10 years.Although diverged greatly among different methods,the accuracy of antibody detection has improved year by year.
