Objectives:To evaluate the efficiency of packing jaw defects with a composite of coral and bone marrow.　Methods:Twelve patients (9 with jaw cyst and 3 with ameloblastoma) underwent enucleation of jaw lesion and packing with a composite of coral and bone marrow.Repair of the bone defects was evaluated at 1 week,1,6 and 12 months postoperatively by clinical examination and X-ray films.　Results:Wound healing after the operations on 10 patients was uneventful,and definite ossification around the implanted material could be detected at 1 month postoperatively.A lot of bone formation and partial resorption of coral were observed at 6 months postoperatively.Complete resorption of coral and complete bone repair were obtained at 12 months postoperatively.Wound breakdown was observed on two other patients,and the composite had to be removed completely.　Conclusions:A composite of coral and bone marrow may enhances bone healing in jaw defects after cyst or ameloblastoma removal.

ObjectiveTo study the effect of testing amino acids levels in brain microdialysate by method of high performance liquid chromatography (HPLC) with α-aminobutyric acid (AABA) as the internal standard.MethodsReversed phase high performance liquid chromatography (RP-HPLC), orthophthaladehyde (OPA) precolumn derivatization method and fluorescence detector were used. The separation was performed using an ODS-C18 column. AABA, an isomeric compound of GABA, served as the internal standard, phosphate buffer solution and methanol as the mobile phase, gradient elution lasted in 35 min.Results7 kinds of amino acids and internal standard were separated completely. The mean recovery of amino acid was 88.2%—102.3%. The mean correlation coeffeicient of the linear relationship was 0.998±0.0015.Limits of detection for amino acids were 1.0—8.6 ppm respectively.ConclusionThe method mentioned above is simple and sensitive for operation, and can be used for determined levels of amino acids in microdialysate.

Due to lack of the practical technique to measure the biomechanical properties of the ocular cornea in vivo, clinical ophthalmologists have some difficulties in understanding the deformation mechanism of the cornea under the action of physiological intraocular pressures. Using Young's theory analysis of the corneal deformation during applanation tonometry, the relation between the elasticity moduli of the cornea and the applanated corneal area and the measured and true intraocular pressures can be obtained. A new applanation technique has been developed for measuring the biomechanical properties of the ocular cornea tissue in vivo, which can simultaneously acquire the data of the applanation area and displacement of the corneal deformation as well as the exerted applanation force on the cornea. Experimental results on a rabbit's eyeball demonstrated that the present technique could be used to measure the elasticity moduli and creep properties of the ocular cornea nondestructively in vivo.

AIM: To study the allergic disease in recurrent tonsillitis. METHODS: Immunohistochemical technique was used to investigate interleukin-4(IL-4) production in tonsil. RESULTS:The result showed that: a higher incidence of IL-4 producing cells were found in the tonsils of all ages, and a high density of IL-4 was found in the reticular crypt epithelium and extrafollicular, but low density in germinalcenter. IL-4 has been shown play a crucial role in the pathogensis of allergic disease. CONCLUSION:Allergic disease is an important reason of recurrent tonsillitis. The conclusion will give a new way to cure recurrent tonsillitis.

Objective To detect the expression of E-cadherin and ?-catenin in breast carcinoma and analyze the relationship between E-cadherin and ?-catenin and the clinicopathological features. Methods The expression of E-cadherin and ?-catenin in breast cancer, paracarcinoma breast tissue, simple mastoplasia and atypical mastoplasia were detected by immunohistochemical method and the results were compared. Results The abnormal expression rates of E-cadherin and ?-catenin in breast cancer tissue were 51.9% and 61.1 %,respectively. Abnormal expression of E-cadherin was significantly correlated with histological grade. Abnormal expression of ?-catenin was significantly correlated with TNM staging, axillary lymph nodes metastasis and postoperative distant metastasis. COX multiple factor analysis showed that neither E-cadherin nor ?-catenin expression was an independent indicator for the prognosis of breast cancer. Conclusions Abnormal expressions of E-cadherin and ?-catenin are correlated with occurrence and development of breast carcinoma. Abnormal expressions of E-cadherin and ?-catenin are good indicators to judge invasion and metastasis of breast carcinoma.

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.
