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 analyze the CT findings of tuberculous lymphadenitis in parotid gland, so as to improve the diagnostic accuracy of tuberculosis of parotid gland. Methods Nine cases with tuberculous lymphadenitis in parotid gland confirmed by surgical pathology and acid-fast bacilli after preoperative spiral CT plain scan and two phases dynamic enhancement scan were retrospectively analyzed.Imaging findings of CT were reviewed and compared with surgical pathology. Results Seven of the 9 cases of tuberculosis of the parotid gland occurred in the left side, and 2 in the right side, and superficial lobe involvement occurred in 8 cases and deep lobe in 1 ease. The lesion was classified as tumour type (8 cases)and infiltration type (1 case). In tumour type, the number of lesion was from 1 to 4, and the size was from 2.7 to 5.3 cm in diameter. One case of infiltration type measured 3.4 cm in diameter. On CT plain scan,the lesions showed homogeneous slight high-density with regular edge in 5 cases and irregular low-density in 4 cases, and 2 of them with partly blurred edge. On CT enhanced scan, uniform moderate enhancement was seen in 3 cases, circular enhancement in 4 cases, inhomogeneous enhancement in 1 case, and lace-like enhancement in 1 case. Local infiltration occurred in 6 cases. Lymphadenovarix in the same side of lesion occurred in 2 cases. Conclusion CT findings of tuberculous lymphadenitis in parotid gland present diversification, which correlate well with pathological changes. Understanding of characteristic CT findings of tuberculous lymphadenitis in parotid gland is helpful for differential diagnosis, but final diagnosis still depends on pathology and acid-fast baeilli.

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.

Objective To evaluate the causes of local masses found after periocular fat grafting,and the way of treatment in order to avoid the medical dispute.Methods In 37 patients with local mass being repaired,15 patients with superficial bulges were treated through surgical removal and as piration;10 patients with focal masses were treated with aspiration;12 patients with bulges close to eyelid margin and failure after the first two treatment methods were treated through incision.Results Histopathologic findings showed the characteristic features of lipogranuloma.Chronic inflammatory cells were infiltrated.Numerous,variable-sized lipid vacuoles were surrounded by histiocytes and for eign body-type giant cells.There were areas of fibrosis and fat necrosis.35 cases were followed-up for 3 months to 1 years.Both doctors and patients were satisfied with results in 27 cases,basically satisfied in 6 cases,but not satisfied in 2 cases.Two patients were lost to follow up.Conclusions The special complication of masses in the periocular fat grafting operation can be greatly improved with the personalized therapy.

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 investigate the development trend of drinking-water-borne endemic fluorosis in Jiangsu Province,and to provide the basis for further prevention and treatment of the disease.Methods In 2009,eight major counties were chosen,and in each county all diseased villages were classified into light,moderate and severe disease types according to water fluorine content based on historical data,and one village was chosen from each type.In monitoring villages with improved water,one source water and three tap water samples were collected,respectively.Five water samples were collected in water unimproved monitoring villages according to water well locations of the east,the west,the south,the north and the center.The fluorine content in water was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006).Children aged 8 to 12 were examined for dental fluorosis by Dean method.Residents over the age of 16 were examined for clinical osteofluorosis,and two monitoring counties were chosen,then one village was respectively chosen in each county,and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray.Both clinical and X-ray diagnosis were on the basis of Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008).Urine samples of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method(WS/T 89-1996).Results Of all the 24 villages of 8 counties,20 villages were water improved,and water-improvedprojects ran normally in 18 villages,while scrapped in the rest 2 villages.One hundred and two samples were tested,and the mean of water fluoride in water-improved villages was 1.10 mg/L,while in water unimproved villages and villages with water improved projects scrapped was 1.90 mg/L.The prevalence of dental fluorosis was 42.51％(854/2009).The prevalence of clinical skeletal fluorosis was 23.23％ (2024/8713) and the X-ray detection rate was 32.00％ (24/75).Six hundred and sixty-four urine samples of children were determined,and geometric mean of urinary fluorine was 1.59 mg/L,while 370 adult urine samples were determined,and geometric mean of urinary fluorine was 2.20 mg/L.Conclusions Endemic fluorosis in Jiangsu Province has not been fully controlled and there are signs of recovery.We must pay attention to water improvement measures to reduce fluoride and the management and maintenance of water improvement projects,and further strengthen the prevention and control of endemic fluorosis.
