[ABSTRACT]OBJECTIVETo investigate the expressions of Endoglin (CD105) and Galectin-3 protein in laryngeal squamous cell carcinoma (LSCC) as well as the relationship between their expressions and the clinicopathological factors of LSCC.METHODSThe expressions of CD105 and Galectin-3 protein were detected in 76 samples of LSCC and 25 normal laryngeal tissues (NLT) by immunohistochemical staining (S-P).RESULTS 1.The mean of Microvessel density (MVD) value marked by CD105 in LSCC was 10.33±2.29, which was significantly higher than that in NLT (1.20±1.04) (P<0.05). The expression of MVD marked by CD105 (CD105-MVD) was correlated with histological grading, T stage, clinical stage, lymph node metastasis, recurrence and prognosis in LSCC (P<0.05). 2.The positive expression rate of Galectin-3 protein in LSCC was 86.84%, which was significantly higher than that in NLT (36%)(P<0.05). The expression of Galectin-3 was correlated with T stage,clinical stage, lymph node metastasis, recurrence and prognosis in LSCC (P<0.05). 3.There was a positive correlation between CD105 and Galectin-3 protein. 4.Survival analysis indicated that the expressions of CD105 and Galectin-3, histological grading, lymph node metastasis,T stage and recurrence were independent factors for tumor prognosis in LSCC (P<0.05). CONCLUSIONThe expressions of CD105 and Galectin-3 protein have a positive correlation in LSCC. They may play important roles in the tumorigenesis, malignant progression and poor prognosis of LSCC. Combined detection of them may be great value in diagnosis and predicting prognosis of LSCC.

Objective To study local people's habits and customs concerning the prevention of dental fluorosis in an indoor coal-combustion-type fluorosis area of Zhaotong city Yunnan province, and to provide reference value for monitoring and control of the disease. Methods In 2008, 600 people of a 12-year-old group (400 people) and a 35 - 44-year-old group(200 people) were examined for dental fluorosis and oral health status in an indoor coal-combustion-type fluorosis area of Zhaotong. A questionnaire survey of 120 students and 60 adults was carried out on their habits and customs, stove changing status, knowledge of prevention of dental fluorosis, social psychology status, oral health behavior and their need for medical treatment. Results The total prevalence of dental fluorosis was 91.0% (546/600), dental fluorosis index was 2.58. The total prevalence of dental fluorosis of 12-year-old group was 86.5%(346/400), and dental fluorosis index was 2.12. The total prevalence of dental fluorosis of rural student was 90.5% (181/200), which was obviously higher in the rural group than the urban group [82.5% (165/200), χ2 = 5.48, P < 0.05]. The total prevalence of dental fluorosis of 35-44-year-old group was 100% (200/200), which was obviously higher than that of the 12-year-old group(χ2 = 29.67, P < 0.01). The rates of using coal, baking of food, changing stoves were 66.7% (60/90), 14.4% (13/90),57.8% (52/90), respectively, and these values of the urban were much lower than those of the rural[95.6%(86/90) ,31.1%(28/90) ,76.7%(69/90),χ2 = 24.51,7.11,7.29, all P < 0.01]. Only 23.3% (42/180) of people surveied had the knowledge of prevention of dental fluorosis, and the rate in the adult group[56.7% (34/60)]was higher than that of the student group [6.7% (8/120), χ2 = 55.9, P < 0.01]. The same rate in the urban student group was 0(0/60), and the rural student group was 13.3%(8/60), there was a significant difference between them(χ2 = 5.66, P < 0.05). Seventy-three point nine per cent( 133/180) of these people thought dental fluorosis had significant effect on their life, 91.1%(164/180) of these 'people wished to be treated. Eighty-four point four per cent( 152/180) of the people had a habit of toothbrushing,and 50.7% (77/152) of these people were still using toothpaste containing fluorine. Conclusions Zhaotong is a serious indoor coal-combustion-type fluorosis area. Enhancing health education to local people especially to students, and changing people's unhealthy habits and customs are keies to control the prevalence of indoor coal-combustion-type dental fluorosis.
