BACKGROUND:Implanted site and direction of miniscrew implants, post-implantation movement of implants, contact between tooth and implant after tooth movement al can cause root damage.
OBJECTIVE:To investigate the changes of the root surface, periodontal tissue and osteoprotegerin expression in the periodontal tissue at periods of time after miniscrew implant loading.
METHODTwo beagle dogs were selected. For each dog, miniscrews were implanted into the labial alveolar bone near the roots of the maxil ary second, third, and fourth premolars and the maxil ary second, third, and fourth premolars and first molar. Fourteen miniscrew implants were in one dog, including six in the maxil ary and eight in the mandible;two miniscrews of the maxil ary acted as control group with no loading, and the rest miniscrews were as experimental group under orthodontics force. Two weeks after miniscrew implantation, 150 g force was loaded between two miniscrews with nickel-titanium closed-coil springs. The dogs were sacrificed after miniscrews loading 4 and 8 weeks respectively, the teeth were cut completely with alveolar bone tissue and decalcified to make the histological specimen. The histological changes of the root and periodontal tissue were observed by hematoxylin-eosin staining and expression of osteoprotegrin in the periodontal ligament was also inspected by using immunohistochemistry.
RESULTS AND CONCLUSION:When the miniscrews were adjacent to the roots, absorption lacuna occurred in the alveolar bone;after horizontal force was loaded opposite to the roots, alveolar resorption became much more animate. When the miniscrews contacted with the pericementum, some areas of the cement absorbed seriously and even reached the dentin;when sustaining pressure from the miniscrews, the whole layer of the cement absorbed and the dentin was exposed and began to be absorbed. The osteoprotegrin in the periodontal ligament of control group expressed sharply and its expression was notable at 8 weeks;while the osteoprotegrin of experimental group weakly expressed at 8 weeks, and there was significant divergence between control group and experimental group at 8 weeks (P<0.01). The roots and periodontal tissue were al damaged variously after miniscrew implantation adjacent to the roots. When horizontal orthodontic force was loaded opposite to the roots, the expression of osteoprotegrin was influenced slightly;as the loading period prolonged, pressure dramatical y restrained the expression of osteoprotegrin. When discovering the miniscrew implant adjacent to roors, the miniscrew implant anchorage should not be used to load orthodontical force opposite to the roots but ought to be removed in order to leave the root repair autonomously and avoid further damage.

Objective To analysis the clinical characteristics, treatment and prognosis for patients with cervical cancer with lymph lode of paraaortic and /or supraclavicular metastasis after combined treatment in two years. Methods Data of 20 patients with lymph lode of paraaortic and /or supraclavicular metastasis of cervical cancer were analyzed retrospectively. Results There was no evidence of lymph node of paraaortic and supraclavicular metastasis before the first combined treatments according to the MRI/CT/SPECT scans in these 20 patients. However, lymph lode of paraaortic and/or supraclavicular metastasis were seen in two years after treatments, the shortest is two months. One patient was progressing during treatment whose pathologic diagnosis is mucinous adenocarcinoma, died in 6 months from treatment start. There was only paraaortic metastasis in 15 patients, among these, 4 patients were found lymph lode of left supraclavical metastasis after retreatments in 3-6 months. Both paraaortic and left-supraclavical lymph node metastasis in 4 cases. Among these 20 cases, recurrence and to give up treatment, whose median survival time is 7.50 months, recurrence and to gain treatment, whose median survival time is 18.98 months, there was significant difference (x2=7.23, P<0.01). Conclusion Patients with cervical cancer with lymph lode of paraaortic and/or supraclavicular metastasis after combined treatment will obviously extend survival time after retretments, which has positive therapy significance.

AIM: To evaluate the clinical effect and the rotational stability of AcrySof Toric intraocular lens ( IOL ) implantation to correct preexisting corneal astigmatism in cataract surgery.
METHODS: Twenty-three patients ( 28 eyes ) were enrolled from the department of ophthalmology in the first Affiliated Hospital of Nanjing Medical University. All patients underwent similar phacoemulsification procedure combined with AcrySof Toric IOL implantation from June 2012 to December 2013. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA ) , anticipated residual astigmatism, postoperative residual astigmatism, and Toric IOL axis were detected and measured.
RESULTS:Three months after operation, the UCVA of all eyes were 0. 75±0. 16 and the BCVA were 0. 84±0. 15, there was no significant difference between UCVA and BCVA ( t = 1. 036, P>0. 05 ). The anticipated residual astigmatism was ( 0. 28±0. 12 ) D. The actual residual astigmatism after 3mo of the operation was (0. 42±0. 17) D. There was no significant difference between anticipated and actual residual astigmatism (t=1. 259, P>0. 05). The mean axis rotation of Toric IOL was 3. 02o±1.56o (0o-7o) after 1d of operation and 3. 28o±1. 85o (0o-7o) after 3mo. Among all the eyes, 25 eyes ( 89%) rotated <5o, in 3 eyes (11%) rotated 5o-7o.
CONCLUSION: The AcrySof Toric IOL implantation shows good effectiveness, predictability and stability in correcting pre-existing astigmatism in cataract patients.

Objective To study the current cases of Keshan disease aims at providing scientific and basic evidence for prevention and control of the disease. Methods In accordance with historical cases, in 2009, an investigation was conducted in the permanent resident population in seriously infected representative villages of landscapes and ways of living such as Xujialeng, Zhuping and some other adjacent villages in Wudu district, Longnan city. People in those areas were examined and carefully observed based on the scheme of Keshan disease surveillance. Then they were enquired about their medical history, given normal clinical examinations and electrocardiogram(ECG) examination, the suspected cases were chest X-rayed. At the same time, some samples of their hair of some children under 12 and adults were collected to be examined for the selenium content. Results Among the total number of 515 subjects, 20 were diagnosed with Keshan disease with a total detection rate of 3.9% (20/515), among whom 13 were potential patients with a detection rate of 2.5%( 13/515), 7 were chronic patients with a detection rate of 1.4%(7/515). In the total number of 515 ECG, 48 were found with abnormal ECG at a detection of 9.3%(48/515). In the 20 patients, the potential patients were mostly featured with incomplete right bundle-branch block(5 cases), complete right bundle-branch block(3 cases), frequent ventricular premature beat (2 cases) and left ventricle high voltage(2 cases), while the chronic patients were mostly featured with incomplete right bundle-branch block(2 cases). Of the 29 chest X-ray films, 17 cases had heart enlargement with a detection rate of 58.6%( 17/29). The selenium content in the hair of 10 adults and 10 children were (0.38±0.09), (0.31±0.12) mg/kg, respectively. Conclusion There are still existing some cases and obvious virulence factors of Keshan disease in Wudu district, Longnan city.

Objective To investigate the relation between body mass index(BMI),skinfolds(SF)and relative weight(RW),arm girth(AG) and ag e of the children in order to look for the most suitable index used to diagnose children obesity in clinical work.Methods In 1496 healthy children (ranging from 1 to 13 years),their weight, height,AG, triceps skinfold(TSF), sub scapular skinfold(SSF) and abdominal skinfold(ASF) were measured and the relat ion of BMI,SF,RW,AG and age was analyzed.Results 1.Between BMI and the sum of three skinfolds(SF3) ,RW,AG,correlation coefficient was more t han 0.8(P＜0.001).2. With the increase of age, AG and ASF increase wh ile TSF and BMI decrease. 3.Skinfolds in girls of 3～6,12 years of age are thicker t han those in boys;BMI in boys of 8,9 years of age are higher than those in girls .Conc lusions 1.95 percentile of BMI and SF3 as index to diagnose children obes ity is better than single application of RW or one-site skinfold. 2. With the i ncrease of age, AG and abdominal fat increase, but triceps and total fat of body relatively decrease. 3. Fats in girls develop faster than in boys.
