Objective To measure the right conus branch in adults with multi-slice CT.Methods 57 cases were detected with multi-slice CT coronary artery angiography. Such data as the length and diameter of the right conus branch, the distance from the origin of theright conus branch to the nearest aortic wall, and to the origin of the coronary artery on the axial images were measured,and the anglebetween the right conus branch and the distal segment of the coronary artery on the VRT image was also made.Results The distribution and shape of the right conus branches could be detected by CT, and with different methods thus data above could be gotten precisely. Conclusion There is a higher significance to detect and measure the right conus branch with multi-slice CT.

Objective To study the value of measurement of sinus node artery in adults with multi-slice spiral CT(MSCT).Methods 119 cases were examined by MSCT coronary artery angiography.The diameter of the sinus node artery,the distance from the origin of the sinus node artery to the origin of the coronary artery(S-O),to the origin of left circumflex branch(LO-O),and to straightly the aortic wall erectly(S-W) and the angle between the sinus node artery and the proximal segment of the coronary artery(the angle of S-C) were measured on axial and MIP images.Results The origin,morphological characteristics of the sinus node artery were shown clearly on CT coronary artery angiography,and the diameter,length,the distance of S-W,S-O and LO-O and the angle of S-C were measured precisely.Conclusion The parameters of the sinus node artery measured by MSCT are basically corresponded with those on anatomy,MSCT may be used to show the sinus node artery.

Objective To identify changes in the occurrence of endemic fluorosis in order to provide scientific basis for making countermeasures. Methods Five villages from 14 counties of mild, moderate and severe fluorosis affected areas were selected by stratified cluster sampling every year in the whole province during 2006 - 2010. Water and urinary fluorine were determined by ion selective electrode method(GB/T 8538-1995); dental fluorosis of children 8-12 years old was diagnosed with Dean method; skeletal fluorosis was diagnosed according to "clinical indexing standards of endemic skeletal fluorosis "(GB 16396-1996), between 2006 and 2008, and "clinical diagnosis standard of endemic skeletal fluorosis"(WS 192-2008) between 2009 and 2010. Results A total of 25 diseased villages were surveyed, 14 with water sources changed, covered a resident population of 8005 people, beneficiary population 7154, and accounting for 89.37% of the resident population; not changed villages 11. In accordance with the "State drinking water health standards", in the 14 changed villages the fluoride in drinking water was qualified (≤ 1.20 mg/L), there were 3 schools whose water fluorine content exceeded the standard; among the 11 villages that did not change water sources 7 drinking water samples fluorine content exceeded the standard. Of the 8 to 12 years old children in villages with changed water sources, 363 of them were checked and 142 dental fluorosis were found, the detection rate of dental fluorosis was 39.12% (142/363); in villages with water sources not changed, 303 children were checked, the detection rate of dental fluorosis was 43.89%(133/303). Of sixteen and elder adults in water source changed villages, 6424 people were checked and 403 skeletal fluorosis were found, skeletal fluorosis detection rate was 6.27% (403/6424); 3572 people were checked in not changed villages, the detection rate of skeletal fluorosis was 13.89%(496/3572). In water sources changed areas, geometric mean of urinary fluoride was in the normal reference value(WS/T 256-2005, 1.40 mg/L)or less. Conclusions Endemic fluorosis is decreased in water improved areas, but in unimproved areas the disease is still severe, and control of endemic fluorosis is still an arduous task.

Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P＜ 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P＜ 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.

Background The injury or surgery of cornea cause the proliferation of corneal stromal cells and scar formation.Recent research showed that cureumin can obviously reduce the degree of fibrosis of tissue.But if curcumm play inhibitory effect on corneal keratocytes fibrosis is rarely reported.Objecttve This studv was to investigate the effect of curcumin on the transformation of corneal keratocytes into fibroblasts in vitro and further explore the antifibrotic effect of curcumin on corneal keratocytes.Methods The murine corneal keratocytes from 150 BALB/c mice were isolated and primary culture in DMEM culture medium containing 10% fetal bovine serum and then divided into blank control group(inducer group,CG),low-dose group(CG+7.5 mg/L curcumin),mediumdose group(CG+10.0 mg/L curcumin),high-dose group(CG+12.5 mg/L curcumin),non-inducer group.Seven days following intervention,the expression of cell markers such as keratocan,aldehyde dehydrogenase(ALDH),decorin and fibronectin-1 in keratocytes were analyzed by RT-PCR.The effect of curcumin on cultured murine corneal keratocytes proliferation was evaluated by MTS technique.The expression of fibronectin-1 in murine cornea was investigated by immunofluorescence assay.Results The primarily cultured keratocytes showed tlIe fusiform-like shape with the abundant cytoplasm and big nuclei.In the presence of curcumin,the mRNA levels of keratocan and ALDH were down-regulated and those of CD90 and decorin were up-regulated,showing the significantly differences with the increase of dose(P<0.05),but the expression pf fibronectin-i was not obviously changed with the alteration of dose of curcumin. MTS showed that the inhibitory rates of curcumin on keratocytes in 10.0 mg/L and 2. 5 mg/L groups were enhanced in comparison with 7.5 mg/L group, showing statistically significant difference among three groups( F = 956.00, P<0.05). The expression of fibronectin-1 was found in the corneal keratocytes with the red fluorescence in stroma. Conclusion Curcumin can inhibit the fibrosis of corneal keratoeytes in a dose-dependent manner. These results offer a preliminary theoretical basis for the application of curcumin in controlling corneal scar formation during wound healing.

AIM: To evaluate the effect of probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment for the treatment of chronic dacryocystitis.METHODS: For 127 cases (129 eyes) of chronic dacryocystitis, first the pyoid secretion gathered in the lacrimal sac was dashed out, and some TobraDex was injected in the middle of the lacrimal passage once per day, repeated for several times. The lacrimal passage was probed when the secretion of lacrimal sac disappeared essentially. The lacrimal passage and immit TobraDex eye ointment was used once every two days, repeated for 3-4 times.RESULTS: In 126 cases (128 eyes) the lacrimal passage was dredged. Only one case (1 eye) the youthful patient did not recover for the opening ectopia of lacrimonasal duct.During the 3mo-1a random visit the chronic dacryocystitis did not recrudesce in the cases of lacrimal passage dredging.CONCLUSION: It is simple and safe to use the probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment to treat the chronic dacryocystitis. This method has good curative effects and can keep the normal physiological structure of lacrimal passage. It does not need any expensive medical equipment and cost less, therefore is advisable for patients.

AlM:To evaluate the clinical efficacy of intravitreal injection of ranibizumab combined with macular grid photocoagulation for diabetic macular edema ( DME) .METHODS:Totally 60 eyes ( 60 patients ) with DME were randomly divided into 2 groups: 30 eyes of simple injection group underwent intravitreal injection of ranibizumab, and 30 eyes of combined treatment group underwent intravitreal injection of ranibizumab and macular grid photocoagulation 1wk later. The best corrected visual acuity ( BCVA ) , central macular thickness ( CMT ) measured by optical coherence tomography ( OCT ) and postoperative complications were observed.
RESULTS:ln simple injection group, the BCVA after operation were separately 0. 390 ± 0. 075 (4wk), 0. 367 ± 0. 088 (8wk) and 0. 319 ± 0. 064 (12wk), the CMT after operation were separately 221. 63 ± 112. 34μm (4wk), 337. 73±99. 56μm (8wk) and 432. 92 ± 100. 46μm (12wk), which were much better than pre-operation. But during follow-up, the BCVA presented down trend and the CMT was on the rise slowly. ln combined treatment group, the BCVA after operation were separately 0. 385 ± 0. 036 (4wk), 0.382±0.079 (8wk) and 0.377±0.097 (12wk),the CMT after operation were separately 249. 77 ± 106. 55μm (4wk), 270. 40 ± 92. 88μm (8wk) and 275. 84 ± 97. 34μm (12wk ), which were satisfactory and steady during follow-up, better than simple injection group (P<0. 05).CONCLUSlON:lntravitreal injection of ranibizumab can effectively improve visual acuity and decrease central foveal thickness for patients with DME, combining with macular grid photocoagulation can ensure therapeutic effects steady and permanent.
