Objective To analyze the correlation between the polymorphism of PTPN22 gene (R620W and R263Q sites)and pulmonary tuberculosis(TB)in Chinese Han population and to investigate the environmental factors associated with pulmonary TB. Methods A case-control study was conducted on 235 patients with pulmonary TB and 251 healthy subjects. The single nucleotide polymorphisms(SNP)of PTPN22 gene at R620W and R263Q sites were detected by the assay of polymerase chain reaction and re-striction fragment length polymorphism(PCR-RFLP). A questionnaire was designed to gather information about tuberculosis-associated environmental factors. Univariate and multivariate logistic analysis were con-ducted. Results Genotype frequencies of PTPN22 R620W(C1858T)SNP were 233(99. 15% ,CC),2 (0. 85% ,CT),0(0% ,TT)in patients with pulmonary TB and 240(95. 62% ,CC),11(4. 38% ,CT), 0(0% ,TT)in healthy subjects. There was a difference with the distribution of PTPN22 C1858T allele be-tween patients with pulmonary TB and healthy subjects[0. 43% vs 2. 19% ,P = 0. 01,odds ratio(OR)=0. 19,95% confidence interval(CI)= 0. 07-0. 35]. Genotype frequencies of PTPN22 R263Q(G788A) were 218(92. 77% ,GG),17(7. 31% ,GA),0(0% ,AA)in patients with pulmonary TB and 248 (98. 71% ,GG),3(1. 29% ,GA),0(0% ,AA)in healthy subjects. The frequencies of G788A allele in patients with pulmonary TB were higher than those in healthy subjects(3. 62% vs 0. 60% ,P﹤0. 01,OR=6. 03,95% CI=2. 12-18. 38). Conclusion The results of this study suggested that the R263Q GG geno-type of PTPN22 gene was associated with the susceptibility to TB in Chinese Han population.

Objective:To investigate the impact of polysomy 17 of breast cancer on testing results of human epidermal growth factor receptor 2 (HER2) and its clinicopathologic significance. Methods:Seventy-one patients with primary invasive breast carcinoma were studied. The HER2 gene and chromosome 17 copy numbers were determined by dual-color fluorescence in situ hybridization (FISH). The testing results were expressed by absolute HER2 gene copy number or the ratio of HER2 to chromosome 17. Based on the FISH testing results and HER2 protein expression determined by immunohistochemistry the results were compared between different groups divided by related clinicopathologic parameters.Results:All patients who had doubtable FISH results, either by absolute HER2 copy number (14 of 71 patients; 19.7%) or by the ratio HER2/chromosome 17 (2 of 71 patients, 2.8%), displayed polysomy 17. Polysomy 17-positive patients had no significant difference with HER2-negative patients in tumor grade, lymph node metastasis, and estrogen receptor (ER) expression (all P>0.05); but compared with HER2-positive patients, they showed lower tumor grade (50.0% vs 81.5%, P=0.025), higher rate of negative lymph node (55.6% vs 25.9%, P=0.045), and higher rate of ER positive expression (83.3% vs 41.7%, P=0.005) and progesterone receptor(PR)positive expression (87.5% vs 44.4%, P=0.003).Conclusion:Compared with HER2 gene amplification group, polysomy 17-positive group tends to have negative HER2 gene expression. Polysomy 17 influences the testing results of HER2 and may be the main factor that caused doubtable results in FISH examination.

Objective: To investigate the clinical value of combined detection of serum miR-378 and miR-21 in gastric cancer (GC). Methods: Eighty-seven patients with GC and 78 patients with colorectal cancer(CRC) from National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences were selected, 83 individuals undergoing healthy physical examination were selected as the healthy controls. The levels of serum miR-378 and miR-21 were detected by quantitative real-time PCR (RT-qPCR) (result data were transformed as log2 for analysis). Results: Relative expression levels of miR-378 in the serum were -1.24, -3.25 and -2.73 in healthy controls, GC and CRC patients, respectively. Compared with the healthy controls, the levels of serum miR-378 were significantly decreased in GC and CRC patients (both P<0.05). Relative expression levels of miR-21 in the serum were 0.11, 2.34 and 2.47 in healthy controls, GC and CRC patients, respectively. Compared with the healthy controls, the levels of serum miR-21 were significantly up-regulated in GC and CRC patients (both P<0.05). Moreover, the serum level of miR-378 in GC patients was inversely associated with tumor clinical stage (P<0.05). However, the level of miR-21 showed no significant differences among patients with different clinical and pathological characteristics (all P>0.05). The area under the receiver operating characteristic curve (AUC), sensitivity and specificity of miRNA-378 to diagnose GC was 0.770, 82.0% and 66.0%, respectively, and were 0.900, 85.0%, and 88.0% of miR-21, respectively. The AUC, sensitivity and specificity of combined detection of serum miR-378 and miR-21 to diagnose GC were 0.930, 92.0% and 87.0%, respectively, while the AUC of combined detection of serum CEA and CA-199 was 0.767, the AUC of combined all of the four factors was 0.946. Conclusion The combined detection of serum miR-378 and miR-21 have a certain effect on diagnosis of GC.
