OBJECTIVE: To observe the expression changes of metadherin (MTDH) and matrix metalloproteinase-9 (MMP-9) in the laryngeal squamous cell carcinoma tissues and to investigate the significance. METHOD: The expression of MTDH and MMP-9 in 54 cases of laryngeal squamous cell carcinoma tissues(observation group) and 30 cases of para-carcinoma tissues (control group) was examined by immunohistochemical method, the correlation between them and their correlations with the clinicopathological parameters were analyzed. RESULT: The positive expression rates of MTDH in the observation group and control group were 64.8% (35/54) and 6.7% (2/30), respectively; the positive expression rates of MMP-9 in the observation group and control group were 70.4% (38/ 54) and 13.3% (4/30), respectively; and there was a statistically significant difference between two groups (all P < 0.01). In the laryngeal squamous cell carcinoma tissues, the expression of MTDH protein was related with degree of differentiation, lymph-node metastasis and TNM stage (all P < 0.05); and the expression of MMP-9 protein was related lymph-node metastasis and TNM stage (all P < 0.05). The expression of MTDH was positively correlated with MMP-9 in the laryngeal squamous cell carcinoma tissues (r = 0.371, P < 0.01). CONCLUSION The high expression of MTDH and MMP-9 was closely related to the occurrence, development and metastasis of laryngeal squamous cell carcinoma, joint detection of the two proteins was valuable for early diagnosis and prognosis of laryngeal squamous cell carcinoma.

OBJECTIVE: To investigate the expression of protein kinase CK2 and its relationship with the development, progress, invasion and metastasis of squamous cell carcinoma of larynx (LSCC). METHOD: Immunohistochemical SP staining method was used to assess the expression of CK2 in 18 cases of normal laryngeal mucosa, 14 cases of polyp of vocal cord, 11 cases of larynx papilloma and 50 cases of LSCC patients. And RT-PCR was used to detect the expression of CK2alpha mRNA and CK2beta mRNA in 50 cases of LSCG patients. The relationship between CK2alpha and CK2p was evaluated. RESULT: The positive expression rate of CK2alpha and CK2beta in normal laryngeal mucosa, polyp of vocal cord and tissues close to carcinoma by 1.0 cm, nonmetastatic lymph nodes were lower than that in tissues close to carcinoma by 0.5 cm and laryngeal papilloma. The positive expression rate of CK2alpha and CK2beta in laryngeal carcinoma and metastatic lymph nodes were the highest among the groups. The expression rate of CK2alpha and CK2beta in tissues of laryngeal carcinoma and metastatic lymph nodes of neck was significantly higher than that of laryngeal papilloma and tissues close to carcinoma by 0.5 cm (P < 0.05). In the group of LSCC, the expression of CK2alpha in G2 and in G3 was significantly higher than that in G1 (P < 0.05). While the age of the patients, TNM stage and lymphatic metastasis didn't change in the expression of CK2alpha obviously. The expression of CK2beta correlates to the differentiation grading and lymphatic metastasis in LSCC patients, but not to the age and TNM stage. The result from RT-PCR was highly consistent with that from immunohistochemical SP staining. There was a positive correlation between the expression of CK2alpha in LSCC patients and that of CK2beta. CONCLUSION The over expression of protein kinase CK2 may be an accelerator to the formation and development of LSCC. Protein kinase CK2 may be one of the predictors for the malignant grade of LSCC. To inhibit the over expression might be new therapeutic methods for LSCC.

OBJECTIVE: To explore the proper diagnosis and therapy method in aged patients with bronchial foreign body. METHOD: A retrospective analysis was performed on 15 aged patients with bronchial foreign body by clinical characteristics. The experience of diagnosis and therapy in these cases were summarized. RESULT: Misdiagnosed or missed diagnosis were found in 6 of 15 aged patients with bronchial foreign body. Three bronchial foreign bodies were taken out successfully under topical anesthesia. Twelve bronchial foreign bodies were taken out under topical anesthesia and balanced anesthesia. No complications happened in all case. CONCLUSION Clinical manifestation of bronchial foreign body is often unrepresentative in most aged patients. The chest X-ray of most cases can not show actual appearance of foreign bodies. In addition, history of foreign body in bronchus is often uncertain. So bronchial foreign bodies have often been misdiagnosed or missed diagnosed in aged patients. Suitable anesthesia method is the key to taking out bronchial foreign body in aged patients.

Summary: The expression of CD44v6 and its relationship with the development, progress, invasion and metastasis of laryngeal carcinoma was investigated. The expression and content of CD44v6 mRNA in tissuess were detected by both RT-PCR and FCM which were respectively extracted from normal laryngeal mucosa, leukoplakia of larynx, laryngeal papilloma, polyp of vocal cord, tissues of laryngeal carcinoma, metastatic and nonmetastatic lymph nodes of neck, and tissues close to carcinoma. The outcome of RT-PCR indicated that the expression rate of CD44v6 mRNA involved in tissues of laryngeal carcinoma and metastatic lymph nodes of neck was the highest (90 %-100 %) compared with that of leukoplakia of larynx, laryngeal papilloma, tissues close to carcinoma by 0.5 cm (55.56 %-60.00 %) and that of normal laryngeal mucosa, polyp of vocal cord, nonmetastatic lymph nodes and tissues close to carcinoma by 1.0 cm was the lowest ( 13.33 %-20 %). The result from FCM was highly consistent with that from RT-PCR. It was suggested that CD44v6 was closely related with the development, progress, invasion and metastasis of laryngeal carcinoma. The outcome from the tissues close to carcinoma by different distance could do help to the determination of incisal edge in surgery abstractly.

PURPOSE: Vascular endothelial growth factor (VEGF) signal transduction mainly depends on its binding to VEGF receptor 2 (VEGFR-2). VEGF downstream signaling proteins mediate several of its effects in cancer progression, including those on tumor growth, metastasis, and blood vessel formation. The activation of VEGFR-2 signaling is a hallmark of and is considered a therapeutic target for breast cancer. Here, we report a study of the regulation of the VEGFR-2 signaling pathway by a small molecule, isomangiferin. METHODS: A human breast cancer xenograft mouse model was used to investigate the efficacy of isomangiferin in vivo. The inhibitory effect of isomangiferin on breast cancer cells and the underlying mechanism were examined in vitro. RESULTS: Isomangiferin suppressed tumor growth in xenografts. In vitro, isomangiferin treatment inhibited cancer cell proliferation, migration, invasion, and adhesion. The effect of isomangiferin on breast cancer growth was well coordinated with its suppression of angiogenesis. A rat aortic ring assay revealed that isomangiferin significantly inhibited blood vessel formation during VEGF-induced microvessel sprouting. Furthermore, isomangiferin treatment inhibited VEGF-induced proliferation of human umbilical vein endothelial cells and the formation of capillary-like structures. Mechanistically, isomangiferin induced caspase-dependent apoptosis of breast cancer cells. Furthermore, VEGF-induced activation of the VEGFR-2 kinase pathway was down-regulated by isomangiferin. CONCLUSION: Our findings demonstrate that isomangiferin exerts anti-breast cancer effects via the functional inhibition of VEGFR-2. Pharmaceutically targeting VEGFR-2 by isomangiferin could be an effective therapeutic strategy for breast cancer.
