Objective To investigate the expression of matrix metalloproteinases-7 (MMP-7) in benign and malignant thyroid tissues and its clinical significance. Methods The expression of MMP-7 in 50 thyroid cancers, 45 adenoma and 20 adjacent noncancerous portion tissues were studied by microwave-LSAB immunohistochemical method. Results The positive rate of MMP-7 in thyroid cancer was 64. 0%, which was significantly higher than 37. 0% in adenoma and 25.0% in adjacent noncancerous portion(X_2=8. 72,6. 52, P < 0.01 ). No correlation was observed between the expression of MMP-7 and histological grading of thyroid cancer. The expression of MMP-7 in lymph node metastasis and Grade Ⅲ~Ⅳ were both higher than that in negative cases and in Grade Ⅰ~Ⅱ ( P < 0. 05 ). The percentage of recurrence and death in MMP-7 positive cases were notably higher than that in negative cases( P <0. 05). Conclusion The expression of MMP-7 can be regarded as a parameter for evaluating the degree of malignancy, biological behavior and prognosis of thyroid cancer.

OBJECTIVE:
To observe the effects of sleeping body posture on sleeping structure and respiratory events in patients with OSAHS.
METHOD:
We assessed the sleeping body position, the sleeping structure, position specific AHI and the Epworth Sleepiness Scale (ESS) in a total of 80 patients with Positional OSAHS. The patients were grouped according to AHI: mild OSAHS (5 < or = AHI <15), moderate (15 < or = AHI < 30) and severe (AHI > or = 30). The polysomnography data and clinical characteristics were compared between each group.
RESULT:
The severe OSAHS group, when compared with the mild and the moderate ones, had a significant different in REM%, NREM%, NREM LSaO2, RDI, S-AHI and L-AHI due to posture (P < 0.05). The severe and the mild OSAHS groups had significant different in MSaO2, LSaO2 due to posture (P < 0.05). The moderate and the mild OSAHS group had significant different in LSaO2, REM LSaO2 and RDI (P < 0.05). In all mild, moderate and severe groups, the LT% were higher than ST%, but the difference was not significant (P > 0.05). For mild-to-moderate groups, there was no correlation between the ESS and the AHI for any position different (P > 0.05). For severe group, the ESS was significantly correlated with L-AHI (r = 0.551; P < 0.01); the REM L-AHI and NREM L-AHI was also significantly correlated with ESS of severe group (r were 0.516 and 0.528, P < 0.01).
CONCLUSION
The L-AHI, NREM L-AHI, REM L-AHI and NREM LSaO2 were considered to monitor the stability of OS-AHS, while REM LSaO2 were consider to clarify the severity of OSAHS.

Objective To investigate the correlation of expression of SLeX and p16 gene protein with the potential of invasion and metastasis in papillary thyroid carcinoma(PTC). Methods The expression of SLeX and p16 gene protein in 69 cases of PTC were studied by microwave-labelled strept-avidin biotin immunohistochemical method. Results The positive rates of SLeX and p16 in PTC were 69.6% and 58.0% respectively. The posi-tive rate of SLeX expression in the patients with tumor invasion and lymphatic metastasis was significantly higher than that without tumor invasion and lymphatic metastasis (P<0.05). But the positive rate of p16 expression in the patients with tumor invasion and lymphatic metastasis was significantly lower than that without tumor invasion and lymphatic metastasis (P <0. 05). There was a negative correlation between SLeX and p16 expression in PTC (P <0. 05). Conclusions Expression of SLeX and p16 protein were closely correlated with the invasive and metastasic potential in PTC. SLeX and p16 could be considered as prognostic indications for PTC.

Objective To understand the status quo of the illness situation and the implementation of prevention and control measures on Kashin-Beck disease( KBD ) in Shandong Province , and provide a scientific basis for assessment and acceptance of the work on eliminating KBD. Methods In accordance with the requirements of the national “Implementation Scheme for Endemic Disease Control in 2012” and the “Shandong Provincial Technical Scheme for KBD Control in 2012”. In four towns of Qingzhou, three epidemic villages were selected as the surveying villages in each town in order to understand the implementation of measures for prevention and control of KBD; information such as population of investigating villages, per capita income, farming, food and the implementation of control measures,etc were included. In each investigating village, 7 - 12 years old children were selected to receive clinical and X-ray examination. When fewer than 50 people in a investigating village , one additional endemic village was included near the investigating village , and all children aged 7 to 12 of the village were checked. The number of cases of clinical degree Ⅰ, Ⅱ, Ⅲand the detection rates, X-ray positive detection rate, the number of cases of metaphysis, epiphysis, distal end of phalanx, carpal bone, triad and the detection rates were calculated, respectively. Clinical and X-ray diagnosis were based on “The Diagnostic Criteria of Kaschin-Beck disease”(WS/T 207-2010). Results A total of 14 epidemic villages were selected to survey in four towns of Qingzhou. In the recent three years in the epidemic areas, measures of supplying Se had not been implemented;measures of resettlement and off-site education had not been implemented either. In the epidemic areas , the main crops were wheat and corn; the staple food was flour which accounted for more than 80%, and the foreign food bought accounted for only 11%. The areas of returning farmland to forest (grass) accounted for 0.32%(36/11 151) of the original arable land, and the areas of replanting economic crops accounted for 1.17%(131/11 151) of the original farmland. A total of 536 children aged 7 to 12 were examined by clinical and X-rays. Patient of KBD was not detected clinically. Six positive patients with metaphyseal changes of KBD were detected by X-rays, and the average X-ray detection rate was 1.12%(6/536). Patients with abnormal epiphysis, distal end of phalanx and carpal bone were not detected by X-rays. Conclusions KBD in Shandong Province has been effectively controlled. Since the cause of KBD is still unknown, it is necessary to build a sustainable long-term control mechanism of KBD;further improve the monitoring system and dynamic monitoring work still need to be strengthened.
