OBJECTIVE
To establish a rapid and accurate PCR method for detecting 24 strains of Burkholderia cepacia complex(Bcc) by comparing three detection methods of loop-mediated isothermal amplification(LAMP), SYTO 9 dye method based on polymerase chain reaction(PCR) and TaqMan probe real-time fluorescent quantitative PCR method( TaqMan probe method).
METHODS
According to the molecular biological information of 24 strains of Bcc in the NCBI database, multiple candidate sequence fragments unique to Bcc were screened out, and specific primer and probe that could simultaneously detect 24 strains of Bcc were designed. At the same time, the detection methods of LAMP, SYTO 9 dye method based on PCR and Taqman probe were explored, and the optimal annealing temperature was optimized and screened. The 39 experimental strains were used to verify the Bcc detection method.
RESULTS
LAMP method could not effectively detect Bcc, SYTO 9 dye method and TaqMan probe method could effectively detect more than 20 strains of Bcc, while TaqMan probe method had higher amplification effect, better detection sensitivity, repeatability and stability, which could meet the requirements of this study.
CONCLUSION
In this study, a TaqMan probe method for rapid detection of Bcc was established. Compared with LAMP method and SYTO 9 dye method, this method has the advantages of fast, simple and high sensitivity, and provides technical support for the rapid detectionof Bcc.

Pharmaceutical water is the most widely used raw material and solvent in the process of pharmaceutical products, which is widely used in the cleaning and disinfecting process of appliances, equipment, facilities and systems, and is involved in the whole process of pharmaceutical products. Pharmaceutical water is one of the main sources of microbial contamination of pharmaceutical products, so the microbial safety of pharmaceutical water is crucial for pharmaceutical quality. This paper mainly introduces the characterization of the pharmaceutical water system, and conducts biofilm analysis. Due to the characteristics of oligotrophic and slow-growing of microorganisms in the pharmaceutical water system, this paper also further discusses the microbiological testing and culture methods of pharmaceutical water, so as to provide reference for the establishment of a scientific and reasonable microbiological testing system, as well as provide an important theoretical basis and new ideas for further research on hard-to-culture microorganisms.

AIM:To explore the association between single nucleotide polymorphism in exon 33 (E33SNP) of thyroglobulin gene and Graves ’ disease ( GD) relapse after antithyroid drug ( ATD) withdrawal .METHODS:The healthy controls (232 cases) and GD patients with discontinued treatment (243 cases) were selected.According to the time of re-lapse, the GD patients were divided into A, B and C subgroups.The A group contained 77 cases of relapse within 1 year, B group contained 86 cases of relapse 1~2 years after treatment and C group contained 80 cases without recurrence within 2 years.The genotypes of E33SNP were identified by RT-PCR.The genotype ratio of thyroglobulin between control group and observation group was comparatively analyzed , and the levels of thyroid-stimulating hormone ( TSH) , free triiodothyro-nine (FT3), free thyroxine (FT4) and thyrotropin receptor antibody (TRAb), ophthalmopathy and goiter size in A , B and C subgroups in different genotype GD patients were investigated .Moreover , cumulative efficiency for patients with different genotypes in the observation group after ATD treatment within 2 years were analyzed .RESULTS:The genotype of E33SNP between observation group and control group had no significant difference , but a significant difference between A , B and C subgroups was observed (P<0.05).The levels of TSH, FT3 and FT4, and goiter size of the patients with different geno-types had no significant difference , while the TRAb levels and ophthalmopathy presented a significant difference ( P <0.05).In addition, the cumulative efficiency within 2 years for GD patients with E33SNP T/T, E33SNP T/C and E33SNP C/C genotypes was 61.8%, 42.6% and 21.3%, respectively, all with significant differences (P<0.05).CONCLU-SION:The GD patients with E33SNP C/C genotype have significantly higher TRAb level and ophthalmopathy rate than those in the patients with E33SNP C/T and E33SNP C/C genotypes, and are more likely to relapse after ATD treatment . The GD patients with E33SNP T/T genotype show a lower recurrence rate .Therefore, combination treatment or other treat-ment modalities may be more reasonable for the GD patients with E 33SNP C/C genotype.

OBJECTIVETo use combined comparative genome hybridization (array-CGH) and conventional karyotype analysis to study the relationship between ultrasonographic abnormalities of fetuses and chromosomal aberrations.
METHODSOne hundred twenty two fetuses with ultrasonographic abnormalities in middle and late trimesters suspected with chromosomal abnormalities were collected between March 2012 and February 2013.
RESULTSThe pregnant women had an average age of 31 yr (22-38), among whom 35 were above the age of 35. The average gestational age was 27(+5) weeks (18-37 weeks), and the most common abnormal findings have involved heart, central nervous system and bones. Multiple malformations were found in 49 cases. The success rate of the combined methods was 100%. In 24 (19.7%) of the cases, a chromosomal abnormality was detected. Among all cases, 16 (13.1%) were detected by the combined method (12.3%). Seventeen cases (13.9%) of chromosomal abnormalities and 4 cases (3.3%) of polymorphic variation were detected by karyotype analysis, and 23 cases (8.9%) of abnormalities were detected by array-CGH. Meanwhile, 7 cases (5.7%) of abnormalities were detected by array-CGH, but the results of karyotype analysis were normal. One case (0.8%) with low level of chromosome chimerism detected by the karyotype analysis was missed by array-CGH.
CONCLUSIONThe results suggested that multiple congenital deformity of the fetus has a strong correlation with chromosomal abnormalities. For fetuses with ultrasonographic abnormalities, array-CGH can improve the detection sensitivity of the chromosomal disease.

Objective To observe BQ123 on lung tissue injury following ischemia-reperfusion of hind limbs in rats.Methods A total of 30 male SD rats were randomly divided into control,I-R,and BQ123 groups,with 10 rats in each group. After 4- hour of ischemia and 4-hour of reperfusion to the hind limbs, ET-1 was measured by radioimmunoassay, levels of myeloperoxidase (MPO) and malondialehyde (MDA) were examined by biochemical method,and the content of P-selectin was examined by ELISA. Immunohistochemical method was used to detect the expressions of Fas,Bcl-2 and Caspase-3 in lung tissues. Pulmonary apoptosis was examined by means of TdT-mediated dUTP nick end labeling ( TUNEL) . Results Compared with the control group,the levels of ET-1,MPO,MDA and P-selectin in lung tissues were all increased significantly in I-R group ( P<0. 01). The expressions of Fas,Bcl-2 and Caspase-3 were 0. 294±0. 003,0. 108±0. 005,and 0. 174±0. 003,significantly up-regulated in the I-R group. The apoptosis rate [(18. 83±2. 86)%] was significantly increased in the I-R group (P<0. 01). Compared with I-R group,the tissue contents of ET-1,MPO,MDA and P-selectin were significantly lowered in BQ123 group (P<0. 01). The expression levels of Fas (0. 115±0. 007) and Caspase-3 (0. 159±0. 006) were decreased,but the expression of Bcl-2 was increased (0. 128±0. 005). The apoptosis rate in BQ123 group was significantly lower [(10. 67±2. 16)%,P<0. 01].Conclusion BQ123 may have protective effects on lung tissue after limb ischemia-reperfusion in rats by means of improving neutrophil aggregation and reducing the expression of proteins related to cell apoptosis.
