Objective To investigate intraspecific and interspecific variation within Malassezia iso-lates from patients with pityriasis versicolor by random amplified polymorphic DNA (RAPD) analysis, to learn the difference between RAPD analysis and physiological and biochemical methods in the typing of Malassezia species, and to explore the relationship between RAPD patterns and Malassezia species. Methods A total of 47 Malassezia isolates were obtained from 34 patients with pityriasis versicolor, and they were classified into 5 species by morphological, physiological and biochemical features, I.e., M. Fin'fur, M. Obtusa, M. Globosa, M. Restricta and M. Sympodialis. Genomic DNA was extracted from the 47 clinical isolates and 10 reference strains (including 7 species) of Malassezia. PCR was performed using 4 random primers including S22, S24, S25 and S33. RAPD patterns were analyzed by NTSYS software and dendrogram was autogenerated. Results Genomic DNA of most strains was successfully amplified with four primers, espe-cially with primers S22 and S24 that resulted in rather stable and clear DNA bands. A total of 82 fragments were amplified from all tested strains. These strains showed both interspecifie and intraspecific variation. Multiple swains were isolated from different body sites of 4 patients and identified into different species by biochemical and morphological typing; those swains from same hosts occupied contiguous positions in the dendrogram and exhibited a high genetic convergence. Conclusion The phenomenon that different strains from a co-host show a high genetic convergence indicates that species specificity and evolution of Malassezia are closely related to its hosts.

OBJECTIVETo study the expression and significance of tumor suppressor in lung cancer 1 (TSLC1) gene methylation, the expression of TSLC1 protein in cervix cancer and precancerous lesions as well as their relationship with HR-HPV DNA infection.
METHODSThe clinicopathological data of 92 cases of different cervical lesions during March 2011 to August 2012 treated in our hospital were collected. There were pathologically confirmed 10 cases of normal cervix, 26 cases of cervical intraepithelial neoplasia (CIN) I, 20 cases of CIN II, 15 cases of CIN III, and 21 cases of cervical cancer. Methylation-specific polymerase chain reaction (MSP) was used to detect the TSLC1 gene methylation status in cervical lesions, immunohistochemistry (SP) was used to detect the expressions of TSLC1 protein in cervical lesions, and the second generation hybrid capture (HC2) method was used to detect the high-risk HPV in cervical lesions.
RESULTSThe expression rate of TSLC1 gene methylation in normal cervical tissue, CIN I, CIN II, CIN III and SCC were 10.0%, 30.8%, 55.0%, 60.0%, 66.7%, respectively, showing a statistically significant difference (P = 0.004). The positive expression rate of TSLC1 protein in normal cervical tissue, CIN I, CIN II, CIN III and SCC were 100.0%, 80.8%, 65.0%, 33.3%, and 23.8%, respectively, with a significant difference (P = 0.004). In the progression from CIN to invasive cervical cancer, there was no significant correlation between TSLC1 gene methylation and HR-HPV DNA infection (P = 0.919), TSLC1 protein expression and HR-HPV DNA infection (P = 0.664). The correlation analysis showed a negative correlation between TSLC1 gene methylation and TSLC1 protein expression (r = -0.674, P < 0.001).
CONCLUSIONSTSLC1 gene promoter methylation may be an early event in the cervical carcinogenesis, become an early sensitive marker, and serve the early prevention and prognostic prediction for cervical cancer.

OBJECTIVETo study the expression and clinical significance of MTDH and VEGF in triple-negative breast cancer (TNBC).
METHODSTissue samples of 168 breast cancers (including 112 TNBC tissue and 56 non-TNBC tissue), 10 breast fibroadenomas and 15 normal breast tissues were collected. Postoperative specimens were examined by immunohistochemistry for MTDH and VEGF expression. The correlation between the expression of MTDH and VEGF and clinicopathological features was analyzed.
RESULTSMTDH and VEGF were expressed in 57.1% and 49.4% of breast cancer patients, 64.3% and 56.3% in TNBC patients, respectively, significantly higher than that in the non-TNBC tissues, breast fibroadenomas and normal breast tissues (P<0.05 for all). Statistically significant correlation was found between the MTDH and VEGF expressions (r=0.356, P<0.001). Moreover, MTDH expression was correlated with tumor size, BMI index, lymph node metastasis, pathological stage, recurrence and metastasis, and the expression of p53 and Ki-67 proteins (P<0.05 for all). The VEGF protein expression was correlated with lymph node metastasis, pathological staging, recurrence and metastasis, and the expression of Ki-67 protein (P<0.05 for all). The patients with high expression of MTDH and VEGF showed a lower DFS and OS (P<0.05 for both).
CONCLUSIONSMTDH and VEGF expression may be correlated with tumor angiogenesis and progression and has the potential to be valuable prognostic factors in patients with TNBC.
