Five genes that are closely related with leukemia were detected and identified using COREMINE Medi-cal, and the abstracts of related papers covered in PubMed were analyzed with the biomedical text mining tool, Chilibot, which showed that leukemia interacts with the 5 genes detected using COREMINE Medical.

Full ceramic prosthesis is becoming the main prosthetic development direction. As an important kind of full ceramic prosthesis, full ceramic veneer has not only natural cosmetic appearance and perfect biocompatibility, but also can preserve tooth structure as much as possible, which would be more easily accepted by patients for cosmetic prosthesis. Many methods, such as slip casting, die casting and CAD/CAM technology are available to make full ceramic veneer. All the methods have their own advantages and disadvantages. Slip casting is easy to be developed widely with low cost, so be used in practical work. In this article, the working process of full ceramic veneer, especially manufacture of removable dies, duplication of refractory models, were introduced, which was supposed to be beneficial for the technicians.

Objective To explore the pattern of lymph node metastasis in patitsen with squamous cell carcinoma of the thoracic esophagus and its significance in lymphadenectomy.Methods The clinical data of 230 patients who received radical esophagectomy with three-field lymphadenectomy was analyzed.The metastatic sites of lymph nodes were correlated with tumor location by chi-square test.Logistic regression was used to analyze the relationship between clinic pathoingical factors and lymph node metastasis.Results Lymph node metastases were found in 133 of the 230 patients(57.8%).The average number of resected lymph nodes was 25.3? 11.4 per patient(range 11～71).The rates of lymph node metastasis were 41.6%,19.44%and 8.3%in the neck,thoracic medi- astinum and abdominal cavity for patients with upper thoracic esophageal carcinoma,33.3%,34.7%and 14%for patients with mid- die thoracic esophageal carcinoma and 36.4 %,34.1%and 43.2 %for patients with lower thoracic esophageal carcinoma.No signifi- cant difference in cervical or thoracic metastatic rate was observed among upper,middle and lower thoracic carcinoma.The difference in lymph node metastatic rate for nodes in the abdominal cavity was significant among upper,middle and lower thoracic carcinoma. The lower thoracic esophageal cancers were more likely to metastasize to the abdominal cavity.Logistic-regression showed depth of tu- mor invasion and angiolymphatic invasion were factors influencing lymph node metastasis.Conclusion Cervical and mediastinal node dissection should be performed independently from tumor location.Abdominal node dissection should be conducted more vigorously for lower thoracic esophageal cancer than of other locations.Patients with greater tumor grade,depth of tumor invasion and angiolymphatic invasion were more prone to develop lymph node metastasis.

ObjectiveTo study the expression of vascular endothelial growth factor (VEGF) and aquaporin 1 (AQP1) in the synovium of rheumatoid arthritis (RA) patients,and their correlation with angiogenesis.MethodsThe expression of VEGF and AQP1 in the synovial tissue was detected with immunohistoehemistry in 7 patients with RA,12 patients with osteoarthritis (OA).The expression of VEGF and AQP1 positive cells and vessels was scored,and the correlation of positive cells with vessels was analyzed.Rank-sum test and Spearman's correlation analysis were used for statistical analysis.ResultsThe expression of VEGF positive cells was significantly correlated with vessels in the synovium of RA group(rs=0.971,P＜0.01 ).No significant correlation was found between VEGF positive cells and vessels in synovium of the OA group (rs=0.235,P=0.462).There was no evident difference in the expression of VEGF positive cells between RA and OA group (Z=-0.390,P=0.711 ).The expressions of AQP1 positive cells were significantly correlated with vessels in the synovium of RA group (rs=0.828,P=0.022).No significant correlation was found between AQP1 positive cells and vessels in the synovium of OA group (rs=0.396,P=0.203).There was no notable difference in the expression of AQP1 positive cells between RA and OA group (Z=-0.302,P=0.773).The expressions of VEGF positive cells were significantly correlated with AQP1 positive cells in RA group (rs=0.891,P=0.007).No significant correlation was found between VEGF positive cells and AQP1 positive cells in OA group (rs=0.338,P=0.283).ConclusionThe expressions of VEGF and AQP1 are significantly correlated with angiogenesis in the synovium of RA,and they play an important role in the pathology of RA.Moreover,there may be synergistic effect between VEGF and AQP1 in RA.

Objective To study the changes of iodine source and the nutritional status of iodine after termination of iodized salt supply in the areas with different water iodine concentrations in Shanxi province,in order to provide scientific bases for developing strategies on control and prevention of iodine deficiency disorders,and to study the cut-off value of water iodine level where iodized salt supply should be stopped.Methods In 2010 in Shanxi province,6 villages with 100％ of non-iodized salt consumption rate were selected as the survey spots based on the iodine concentration in drinking water of 0-,50-,100-,150-,300-,≥500 μg/L.Villages'iodized salt supply was terminated thoroughly.In each village,20 children aged 8 to 10 were selected.At the same time,women of childbearing age 18 to 50 years old and adult men aged 18 to 60 were selected from the same families as the children.Diet surveys were conducted by the method of 3 days recall on all subjects.Drinking water samples,staple foods,supplementary foods and urinary samples of all subjects were collected and the iodine concentration was determined by arsenic-cerium catalytic spectrophotometry.Results ①In the villages of water iodine 25.9,70.6 μg/L,the medians urinary iodine of children,women and men were all ranged from 100 to 199 μg/L,which meant their iodine nutrition levels were appropriate.In the village of water iodine 109.0 μg/L,the medians urinary iodine of children,women and men were all ranged from 200 to 299 μg/L,which meant their iodine nutrition levels were more than appropriate.In the villages of water iodine 225.8,430.0,581.2 μg/L,the medians urinary iodine of children,women and men were all ≥ 300 μg/L,which meant their iodine nutrition levels were too high.②)In all the 6 villages,the intaking amount of iodine met and exceeded the standard recommended intake of dietary iodine by ICCIDD/UNICEF/WHO (8 to 10-year-old children ≥ 120 μg/d,women of childbearing age and adult men ≥ 150 μg/d).But in the village of water iodine 581.2 μg/L,the iodine intake was exceeded the daily maximum safe intake (children aged 8 to 10 ≤800 μg/d,women of childbearing age and adult man ≤ 1000 μg/d).③The amount of iodine ingestion from drinking water was increased with the water content of iodine.When water iodine exceeded 100 μg/L,the amount of iodine ingestion from drinking water was higher than from food intaking,and became a main resource of iodine in the human body.Conclusions In the counties of iodine concentration in drinking water above 100 μg/L in high iodine areas of Shanxi province,the water iodine becomes the most important source of iodine,and iodine nutritional level is more than appropriate or possible excess.It is recommended that in areas of high water iodine of Shanxi province,the standard cut-point of water iodine value is set to 100 μg/L.

Objectives Understanding the characteristic changes of Keshan disease (KD) in different epidemic period to provide reference basis for prevention and teatment. Methods On the basis of medical record as fundamental element, the relative conditions of Keshan disease's prevailing and spreading period were compared. Results In high incidence years, familial aggregation [accounted for 12%(6/50)] and seasonal aggregation were found, and KD cases occurred mainly from May to September, which was 78% (39/50)of the total cases in the whole year. Circulatory dysfunction(gallop rhythm, pulmonary role, jugular venous engorgement, cyanosis of lips) was more severe in high incidence years than that in low incidence years(X2=8.53,P<0.01). The average age of incidence was (4.07±1.46) years old in high incidence years and (6.11±2.71) years old in low incidence years. The type constitution in high incidence years was significantly different from that in low incidence years (X2=40.68, P<0.01), and chronic type of KD accounted for 22.85%(707/3094),46.09%(53/115), respectively, in high and low incidence years. Conclusions Making a further research of seizure of disease, and improving diagnosis and cure management level are also the important content for prevention and cure research work of Keshan disease at right time.
