Objective To investigate the state of endemic fluorosis, running status of water improvement project to reduce fluoride in Jiangsu province, and to provide a scientific basis for prevention and control of endemic fluorosis. Methods In 2008, in the ten key counties of endemic fluorosis (zone), in Xuzhou,Lianyungang and Suqian, a stratified sampling method was employed to select 40 diseased villages according to their past water fluoride survey data. All children aged 8 to 12 were examined dental fluorosis, and all adults over 16 years were examined clinical skeletal fluorosis. Thirty per cent of the 40 diseased villages were selected, and 20 adults over the age of 16 in each selected village were examined by X-ray, respectively;50% of the 40 diseased villages were selected, and 30 any time urine samples of children aged 8 to 12 in each diseased village were tested urine fluoride. In each city, select a county, the status of water improvement project to reduce fluoride, water supply capacity and coverage in the county were investigated. Results A total of 3560 children aged 8 to 12 were examined, the detection rate of dental fluorosis was 38.51% (1371/3560), tooth defect rate was 5.34% (190/3560), and dental fluorosis index was 0.8. Seven hundred and eight urine samples were tested, the median urinary fluoride was 1.47 mg/L and the range was 0.08 ~ 10.08 mg/L. Clinical detection of skeletal fluorosis was 21.3% among adults over the age of 16, and X-ray detection rate of skeletal fluorosis was 39.2% (123/314).Investigated a total of 248 facilities of centralized water improvement projects, no funds to run or damaged 49, the water fluoride > 1.0 mg/L was 18. Conclusions Endemic fluorosis in Northern Jiangsu province has not been controlled completely, but has a rising trend, we should further strengthen the supervision of water fluoride reduction.

Objective To construct human surfactant protein B (SP-B) gene promoter luciferase reporter plasmids and detect their transcriptional activities in H441 cells.Methods (1)The fragment of SP-B promoter (-218/+ 435 bp) was acquired from human genome DNA by polymerase chain reaction (PCR) amplification and then was inserted into pGM-T vector by the T4 DNA ligase.The vector was transfected into TOP10 E.coli.The positive clone was identified by DNA sequencing.The identified target SP-B promoter sequence was cloned into pGL3-basic vector to construct the recombinant vector pGL3-basic-SP-B-promoter and was identified by enzyme digestion and sequencing; (2)The pGL3-basic-SP-B-promoter vector was converted into pGL4.17-SP-B-promoter vector through enzyme digestion.The identified recombinant vectors and control plasmid pRL-TK were transfected into H441 cells by lipofectamine 2000,and luciferase assays was performed using the dual-luciferase reporter assay system.Results The sequences of SP-B promoter in the recombinant luciferase reporter plasmids were consistent with the one published on Genebank.The firefly/renilla luciferase activity ratio of pGL3-basic/pGL4.17-SP-B-promoter vector (2.8 ± 1.1,66.5±3.8) was significantly higher than pGL3-Basic,pGL4.17 control vector (0.2 ±0.1,4.3 ±0.4) with statistical significance (t =4.182,27.419,P =0.000),respectively.The SP-B promoter activity of pGL4.17-SP-B-promoter vector was significantly higher than pGL3-basic-SP-B-promoter vector (t =27.712,P =0.000).Conclusions The pGL3-basic/pGL4.17-SP-B-promoter vectors are successfully constructed with SP-B promoter activity in H441 cells and pGL4.17-SP-B-promoter vector is the better choice for further study with higher luciferase activity.

Objective To study the expression and clinical correlation of miR-141 in peripheral blood and tumor tissue in elderly patients with rectal cancer.Methods Rectal tumor tissue and tumor-adjacent normal tissues were taken in 75 cases of rectal cancer.The expression levels of miR-141 in peripheral blood and tumor tissue as well as tumor-adjacent normal tissues were determined by real-time polymerase chain reaction method.The correlation of miR-141 expression between peripheral blood and tumor tissue,and the correlation of peripheral blood miR-141 with clinicopathologic features and clinical prognosis were analyzed.Results (1) Compared with peripheral blood in the subjects undergoing normal physical examination or tumor-adjacent normal tissue in the patients with rectal cancer,the miR-141 expression level in peripheral blood and tumor tissue in the patients with rectal cancer was decreased significantly (P<0.01).(2) The cancer tissue miR-141 level in the patients with lymph node metastasis was positively correlated with peripheral blood miR-141 level (r=0.694,P<0.01),and cancer tissue miR-141 level in the patients without lymph node metastasis was positively correlated with peripheral blood miR-141 level (r=0.725,P<0.01).(3) The differences between peripheral blood miR-141 level with tumor stage,tumor differentiation degree and lymphatic metastasis had statistical significance (P<0.01).(4)The postoperative 6-month follow up displayed that among 75 cases,13 cases(17.33%) appeared replase/ metastasis,and peripheral blood miR-141 level was (2.64±0.34),which was significantly lower than that in the patents without replase/metastasis (P<0.01).Conclusion Expression variation trend of miR-141 in peripheral blood is similar to that in tumor tissue,which can reflect the clinicopathologic feature in the patients with rectal patients.

OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.
