OBJECTIVE To search a method for identifying Clostridium perfringens and genotyping their toxin for gene diagnosis by multiplex PCR.METHODS The mutiplex PCR was developed with three sets of primers(designed) based on the sequences of three C.perfringens toxin genes(CP?,CP? and CPE) published in GenBank to identify C.perfringens and genotype their three toxin genes.RESULTS Three expected(sequences) were (obtained) successfully by multiplex PCR and identified by electrophoresis.CONCLUSIONS The(specific) sequences of C.perfringens could be amplified and their three genes of toxins could be identified by this multiplex PCR(system).Such method should be helpful for developing gene diagnosis well.

AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

ObjectiveTo investigate the expression and significance of CD28- cells, CD4+ and CD8+T lymphocytes in the peripheral blood and synovial fluid in patients with rheumatoid arthritis ( RA ). Methods The expression of CD28, CD4+, CD8+ T lymphocytes and inducible co-stimulator(ICOS) in the peripheral blood and synovial fluid in 45 patients with RA were detected by three-color flow cytometry. Independent sample's t test was used for statistical analysis between the two groups. ResultsSynovial fluid CD4+CD28+ICOS+, CD4+CD28- ICOS+ , CD8 + CD28 + , CD8 + CD28 + 1COS+ T lymphocytes were significantly increased than the peripheral blood in RA patients[(36±19)％ vs (15±8)％, t=-4.234, P＜0.01; (2.1±2.2)％ vs (0.6±1.4)％, t=-3.143, P＜0.01; (62±15)％ vs (47±18)％, t=-2.885, P＜0.01; (9±9)％ vs (3±3)％,t=-2.131, P＜0.05], Synovial fluid CD8+CD28-T lymphoc-ytes were significantly reduced than the peripheral blood[(38±15)％ vs (54±18)％, t=2.975, P＜0.01], Synovial fluid CD8+ CD28-ICOS+, CD4+CD28+and CD4+ CD28- T lymphocytes had no significant difference than the peripheral blood (P＞0.05). Compared with peripheral blood in the same patients with RA, CD4+CD28+ ICOS+, CD8+ CD28+ T lymphocyteswere significantly increased[(38±18)％ vs (16±10)％, t=-4.065, P＜0.01 ; (61±16)％ vs (41±21)％, t=-4.065,P＜0.01], CD8+CD28-T was significantly reduced[(39±16)％ vs (59±21)％, t=2.949, P＜0.01]. The level of CD4+ CD28-, CD8+ CD28-, CD28-ICOS+ T lymphocytes in the active and remission patients with RA was not significantly different (P＞0.05). ConclusionSynovial fluid CD28T lymphocyte subsets disturbance and the abnormal expression of ICOS in patients with RA may play important roles in the mechanism of joint damage.

Objective To establish a rapid detection approach by visual interpretation directly for OprD2 resistance gene of Pseudomonas aeruginosa based on the Loop-mediated isothermal amplification (LAMP),and provide a quick and effective method for clinical monitoring of Pseudomonas aeruginosa strains.Methods Totally 47 strains of Pseudomonas aeruginosa collected from December 2011 to June 2012 in Southwest Hospital of microorganisms were prospectively studied.Four LAMP primers (two inner,two outer) were designed according to the six zones of the OprD2 gene of Pseudomonas aeruginosa.A positive reaction is indicated by the color change after adding an intercalating dye (hydroxy naphthol blue) to the reaction solution.This method was used to detect and analyze the distribution of OprD2 resistance gene in 47 strains of Pseudomonas aeruginosa and its coirelation with antibiotic resistance.Results The LAMP assays showed 100％ specificity for the OprD2 gene,and the sensitivity (with the lowest detection limits of 17.414 μg/L) was 10-fold higher than that of conventional PCR assays.The OprD2 gene was negative in 23 strains by both conventional PCR and LAMP.In OprD2 negative strains,the resistance rate of cefotaxime,levofloxacin,aztreonam,piperacillin,imipenem and meropenem was 100％ (23/23),57％ (13/23),48％ (11/23),48％ (11/23),48％ (11/23) and 43％ (10/23).Compared with the OprD2 positive strains,statistical analysis showed that the resistance rate of imipenem,levofloxacin and meropenem in OprD2 negative strains increased significantly (chisquare value is 9.155,4.846,4.037,P value was 0.002,0.028,0.045,and so there was significant difference).Conclusions The established LAMP approach in this study enables rapid,sensitive and specific detection of OprD2 gene in Pseudomonas aeruginosa by visual interpretation.Deficiency of OprD2 gene confers Pseudomonas aeruginosa a basal level of resistance to carbapenems especially to imipenem.The identification of OprD2 gene distribution in Pseudomonas aeruginosa is helpful to the selection of antimicrobial agents in the infection treatment.
