Objective To determine the iodine content of common foods in different geographical areas (coastal city,coastal rural area,mountainous city and rural area) in Fujian Province and provide basic data for evaluation of dietary iodine intake.Methods In 2010,based on the types of food of the total diet study,one food sample(consumption rate is greater than 1％) was collected in coastal city(Taijiang),coastal rural area(Xiang'an),mountainous city (Sanyuan) and rural area(Mingxi).These foods including cereal,beans,potato,meat,eggs,milk,aquatic products,vegetables,fruits,sugar,beverages,liquor and seasoning,and so on 184 kinds of common foods.The iodine content of these food was tested by As (Ⅲ)-Ce4+ catalytic spectrophotometry.Results Among the 184 kinds of food tested,164 were not indicated food iodine content in the Chinese Food Composition Tables (2004).The iodine content of common food in Fujian Province in descending order were salt (30 000 μg/kg),aquatic products(341.4 μg/kg),eggs(255.9 μg/kg),dairy(106.7 μg/kg),meat(103.2 μg/kg),cereals (40.7 μg/kg),vegetables(30.7 μg/kg),beans(12.9 μg/kg),sugar(8.5 μg/kg),fruits(6.7 μg/kg),potatoes(2.4 μg/kg) and alcohol(2.1 μg/kg).The iodine content of kelp and laver was the highest in all the food,which was 314 780.1,176 956.5 μg/kg,respectively.The iodine content of food from animal(241.4 μg/kg) was much higher than that of the food from plant(25.4 μg/kg).The iodine content of common cereals,potatoes,beans,sea algae,meat,eggs and aquatic products was compared in the four areas,and the difference was not statistically significant (M =135.5,20.0,42.0,16.0,54.0,4.0,x2 =1.4,all P ＞ 0.05).The iodine content of vegetables and fruits was compared,and the difference was statistically significant (x2 =8.5,M =204.5,all P ＜ 0.05).Conclusion The iodine content of different foods is different.

Objective:To investigate the effects of experimental periodontitis on serum C reactive protein(CRP) and insulin resistance in obese rats.Methods:4 week old SD rats (n=35)were fed with high fat diet for 16 weeks to establish the model of obesity.According to the obesity criteria,5 rats were screened out.According to the proportion of 1:2,10 rats were randomly selected as obese control group,20 obese rats were used for the establishment of the obesity with periodontitis model(combination group) by periodontal ligation using silk thread.4 rats died after ligation.Before periodontal ligation,1 and 4 weeks after periodontal ligation,orbital venous blood were collected for the detection of fasting blood glucose and fasting insulin.Homeostasis model assessments of insulin resistance index(HOMA-IR) and beta cell function index(HOMA-β) were calculated.The level of serum CRP was examined by ELISA.Results:The level of CRP in the combination group was increased 1 week after periodontal ligation,and then gradually decreased in the following 4 weeks(F=7.773,P=0.004).HOMA-IR in the combination group were higher than that in the obese group(F=-4.691,P=0.000),and beta cell function index was significantly lower(F=3.672,P=0.002) than that in the control group 4 weeks after periodontal ligation.Conclusion:The experimental periodontitis may affect the serum level of CRP in obese rats,aggravate insulin resistance and decrease the function of beta cells in obese rats.

Objective: To investigate the long-term outcome of anterior decompression and bone graft fusion for cervical spondylotic myelopathy(CSM) and factors affecting the outcome. Methods: Two hundred and forty-five patients with CSM were treated with anterior cervical decompression and auto iliac bone graft fusion, of whom 31 had a second operation between 4 months and 2 years after operation. Follow-up studies were carried out within 5 to 15 years after operation, averaging 6.8 years. Results: Function evaluation: excellent in 118 cases (48.16%), good in 71 (28.98%), passable in 35 (14.29%) and poor in 21 (8.57%). According to the 40 points score method, there was an average of 8 point increase in all cases, of which 101 were between 36 to 40 points, 54 between 31 to 35 points. Conclusion: The long-term outcome of surgical treatment for CSM is definite. Significant factors affecting the outcome include timing of operation, degree of pathology and technique of surgery.

Mink plasmacytosis, caused by Aleutian Mink Disease Virus (AMDV), poses a threat to the development of the animal fur industry. Neutralizing antibodies against AMDV may result in a persistent infection rather than providing protection for minks. To date,no specific methods to prevent or cure this disease have been developed. In order to eliminate mink plasmacytosis, antibody detection technology has been used globally as a dominant approach to screen for AMDV-positive minks. This paper introduces the classical technology, counterimmunoelectrophoresis and emerging technology in terms of AMDV antibody detection,and provides a glimpse into the future development of these technologies.

ObjectiveTo investigate the occurrence of new cretinism cases and the prevalence of endemic goiter in iodine deficiency disorders(IDD) high-risk areas of Fujian province,so as to put forward target prevention and control measures for these areas.Methods Twelve counties from Xiuyu,Xiangan,Pingtan,and Dongshan were chosen into the survey by simple random sampling,searching for new cretinism cases were carried out in children under 10 years old.Two schools were chosen in every county and the thyroid volume of forty children aged 8 - 10 were determined by B-ultrasonography methods and their urinary iodine(UI) was determined by As3--Ce4+catalytic spectrophotometry in each school.Twenty women of child-bearing age aged 18 - 40 were chosen for collecting edible salt and urine samples,and the salt iodine content was determined using self-quantitative kit and their UI was also determined by As3--Ce4+ catalytic spectrophotometry.Results In the 4 high-risk counties,no cretinism cases were found.The goiter rate of children aged 8 - 10 was 3.6％(37/1027),and that in Dongshan county was 5.4％(13/240),which was higher than the national standards for eliminating IDD( ＜ 5％).The median urinary iodine(MUI) of children aged 8 - 10 was 175.3 μg/L,and the MUI of women aged 18 -40 was 152.7 μg/L.The coverage rate of iodized salt was 82.7％(382/462).ConclusionsNew case or suspected new case of cretinism is not discovered in the high-risk areas of IDD of Fujian province,and median urinary iodine level of people is in the adequate range.

Objective To analyze the monitoring results of patients with iodine deficiency disorders,and to find out the eliminating process of iodine deficiency disorders and the iodine nutritional status of population before adjustment of iodine level in edible salt in Fujian Province.Methods Thirty counties(cities,districts) were sampled by population proportion probability sampling in the whole Province in 2011; one primary school was selected from each of those 30 counties(cities,districts) ; 40 children aged 8-10 were selected from each of those 30 primary schools; thyroid volume of these children was examined by type-B ultrasound and the iodine level in edible salt from those 40 households was tested by the method of direct titration.Twelve urine samples of those 40 children were collected randomly,and urinary iodine level was tested by arsenic cerium catalytic spectrophotometry.Resident's per capita salt intake was calculated by the three-day-weighing method.In the village(where the school was in),5 drinking water samples were collected in the north,the south,the east,the west and the center of the village.If the water supply was centralized in the village,then 2 tap water samples were collected.Water iodine level was determined by arsenic cerium catalytic spectrophotometry.Three townships(towns,street offices)were selected in the vicinity of those schools; 5 pregnant and 5 lactating women were selected in each of those 3 townships (towns,street offices).Their urinary iodine level was determined by arsenic cerium catalytic spectrophotometry.Results Totally 1219 children aged 8 to 10 were examined,and their goiter rate was 4.92％(60/1219).Three hundred and sixty three urine samples were tested,and the median urinary iodine level was 223 μg/L.Among them,urinary iodine ＜ 50 μg/L accounted for 5.2％ (19/363),and ＜ 100 μg/L accounted for 14.6％ (53/363).The median urinary iodine level of pregnant women was 147.2 μg/L,and 52.0％(235/452) of them were less than 150 μg/L.The median urinary iodine level of lactating women was 134.1 μg/L.The consumption rate of qualified iodized salt was 94.4％ (1143/1211).Per capita daily salt intake was 6 g,and 81.4％ (293/360) of the residents' intake was less than 9 g.The median iodine content of drinking water was 6.2 μg/L,and 89.5％ (68/76) of them was less than 10 μg/L.Conclusions All indicators have met the national standard of eliminating iodine deficiency disorders in Fujian Province in 2011.But there is an iodine deficiency problem in pregnant women,and these women should be given extra iodine supplement.

Objective To explore the mechanism of the experimental periodontitis and initial periodontal therapy on insulin resistance of obese rats associated with periodontitis.Methods Blood samples were collected from SD rats of obese group,periodontitis associated with obese group,periodontal therapy group and control group.Body index,data about insulin resistance and Observed pathological changes were calculated.Results Comparison of four groups:more severe insulin resistance and islet structural dysfunction was observed in obesity with periodontitis group than that of group with obesity alone.After periodontal therapy,inflammation and insulin resistance may be improved.Results from pathological specimens also supported this result.Conclusions The periodontitis with obesity can enhance the inflammatory state of obesity and cause the deterioration of insulin resistance.The initial periodontal treatment can relieve the inflammation of obesity with periodontitis and improve the resistance of insulin.It may be the reason of insulin resistance when obesity with periodontitis that the signaling pathways of IRS-1 and IRS-2 blocked,and PDX-1,GK,GLUT and other protein expression inhibited.

The COI gene as DNA barcode was used to identify the Manis pentadactyla and its adulterants in order to provide a scientific basis for the molecular identification of M. pentadactyla. Genomic DNA was extracted from experimental samples using the DNA extraction kit. The COI genes were amplified using polymerase chain reaction (PCR) and sequenced bi-directionally. Obtained sequences were assembled using the CodonCode Aligner. The neighbor-joining (NJ) tree was constructed by MEGA 6.0. The results indicated that COI sequences were successfully amplified and NJ trees results indicated that M. pentadactyla and its adulterants can be easily identification. Therefore, the COI gene is an efficient barcode for identification of M. pentadactyla and its adulterants,which will provide a new technique for the market supervision.

OBJECTIVETo evaluate the effects of periodontal treatment on the clinical response, systemic inflammatory parameters, and metabolic control of type 2 diabetes patients with moderate to severe periodontitis.

METHODSA total of 56 patients with mean clinical attachment level (CAL)>3 mm were included in the subgroup analysis. A repeated-measures ANOVA (group factor: treatment group and control group; time factor: initial visit, 1.5, 3, and 6 months) was used to analyze the probing depth (PD), CAL, bleeding on probing (BOP), high-sensitivity C-reactive protein (hsCRP), glycated hemoglobin (HbA1c), and fasting plasma glucose.

RESULTSSignificantly lower PD (F=62.898, P-0.000), CAL (F=51.263, P-0.000), BOP (F=75.164, P=0.000), hsCRP (F=6.391, P=0.010), HbA1c(F=4.536, P=0.011), and fasting plasma glucose level (F= 3.073, P=0.031) were observed after therapeutic periodontal improvement. The inter-group differences for PD (t=-2.050, P=0.045), BOP (t=-4.538, P=0.000), and hsCRP (t=-2.261, P=0.028) were statistically significant after therapy.

CONCLUSIONNon-surgical periodontal treatment can effectively improve periodontal status, circulating inflammatory status, and metabolic control of diabetic patients with moderate to severe periodontitis.
