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.

The genetic diversity of three Tibetan herbs, i. e., Sang-Di, E-Dewa and Ye-Xingba (Tibetan names), was studied based on the field collection, specimen identification and DNA sequence analysis. Swertia hispidicalyx, Gentiana lhassica and Scrophularia dentata, as the original plants of the three Tibetan herbs, were collected and identified. The regions of ITS, matK, rbcL, rpoC1, trnL(UAA), psbA-trnH, atpB-rbcL, trnS (GCU)-trnG(UCC), rpl20-rps12, trnL(UAA)-trnF(GAA) and nadl 2nd intron were amplified and sequenced. The ITS regions of S. hispidicalyx and S. dentata were cloned and sequenced, and the sequences were classified into different genotypes. All the sequences were analyzed and compared with those of closely related species. Our studies may provide reference for the genetic diversity analysis and molecular identification of the three Tibetan herbs.

OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

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.

In the basis of a large amount of literatures, this article sumed up the characteristics and application of eggshell membrane.

AIM: To evaluate the safety and efficacy of intravitreal bevacizumab ( avastin ) injection in patients with exudative age related macular degeneration ( AMD) .
METHODS: The records of patients treated with intravitreal injection of 1. 75mg bevacizumab for AMD were retrospectively reviewed. All patients were evaluated by complete ophthalmic examination, optical coherence tomography and fundus fluorescein and/or indocyanine green angiography. Observation was made on the best corrected visual acuity ( BCVA) , intraocular pressure, and the changes of lens, vitreous, central retinal thickness (CFT) and total macular volume (TMV), at 1d, 3d, 7d, 1mo and 6mo after the treatment and then compared with those of pre - operation. Repeated treatment with intravitreous bevacizumab occurred if there were signs of persistent or recurrent exudation. And all cases were followed up at least 6mo. An intravitreal injection of bevacizumab (1. 75mg) was given once every 6wk.
RESULTS:All 50 eyes of 48 patients with the average of 58±20. 46 years old were included. The mean baseline of BCVA and CFT were 0. 82±0. 53, and 364. 97±151. 83μm respectively. Although there was no significant decrease in mean CFT and TMV one week after the injection, the mean BCVA had significant improvement. At the last visit of 9. 7mo follow - up, BCVA, CRT and TMV showed significant improvements over baseline values. BCVA was improved by at least two lines in 32 eyes (64%),remained stabilization in 18 eyes (36%) at the last visit. A total of 98 injections were performed and the average number of injections was 1. 98 for each eye in the group. About 50%of re - injections gained at least two lines of vision improvement one week postoperatively. There were no serious adverse events during the treatment.
CONCLUSION: Intravitreal bevacizumab ( avastin ) injection for managing CNV due to age-related macular degeneration is safe and few side effects. Intravitreal avastin associated with improvement in visual acuity ( VA ) , which can reduce macular edema and choroidal neovascularization leakage. But a prolonged treatment effect needs further observation.

ObjectiveTo investigate the value of 18F-FDG SPECT myocardial imaging in evaluating haemodynamic change,treatment outcome and prognosis for idiopathic pulmonary arterial hypertension (IPAH).MethodsAll 24 patients with IPAH underwent 18 F-FDG SPECT myocardial imaging.Right ventricle/left ventricle (RV/LV)-FDG uptake was calculated by ROI method drawing over the central areas of left and right ventricular free walls.All patients underwent right heart catheterization within 3 days after imaging studies.Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were recorded.After six month pharmaceutical treatment,15 IPAH patients were re-examined with 18F-FDG SPECT myocardial imaging followed by repeated right heart catheterization within 3 days.Plasma N-terminal pro-brain naturetic peptide (NT-proBNP) and endothelin-1 ( ET-1 ) were measured in 17 patients using electrochemiluminescent immunoassay and enzyme immunoassay respectively.All patients were followed up for 12 months at least.Correlations between RV/LV-FDG uptake and mPAP and PVR were determined by simple linear regression analysis.Change of RV/LV-FDG before and after treatment was calculated using Student's t-test.Survival in groups with RV/LV FDG uptake ≥ 1.15 and RV/LV-FDG uptake ＜ 1.15 were compared using Log-rank test.ResultsSignificant correlations were found between RV/LV-FDG uptake and mPAP (r =0.562,P ＜ 0.01 ),and between RV/LV-FDG uptake and PVR ( r =0.574,P ＜ 0.01 ).There were no significant correlation between RV/LV-FDG uptake and NT-proBNP( r =0.18 1,P ＞ 0.05 ),but a significant correlation between RV/LV-FDG and ET-1 was observed (r =0.669,P ＜ 0.01 ).The RV/LV-FDG uptake in patients with positive treatment outcome ( n =6) decreased from 1.38 ± 0.52 to 0.92 ±0.26 (t =4.018,P ＜ 0.05) after 6 months treatment.In contrast,no significant change of RV/LV-FDG uptake was seen in those patients (n =9) with negative treatment outcome ( t =1.861,P ＞ 0.05 ).The mean follow-up time was (21 ±8) months.Mean survival time for the patients with RV/LV- FDG uptake ≥ 1.15was 28 months (95％ confidence interval:24-32 months),which was significantly lower than 34 months survival (95％ confidence interval:33-35 months) for the patients with RV/LV-FDG ＜ 1.15 (x2 =3.956,P ＜0.05 ).Conclusions Detection of right ventricle myocardial glucose metabolism level with 18F-FDG SPECT may be a practical method for evaluating haemodynamic change,treatment outcome and prognosis of IPAH.
