Objective: To investigate alveolar bone remodeling on both labial and lingual aspects of lower anterior teeth during treatment and retention stage. Methods: Forty-three cases with lower first premolars extracted (34 girls and 9 boys) and full records at three time points (pretreatment, posttreatment, follow-up) were collected as study sample. Displacement of lower incisor and bone thickness around its labial and lingual aspect were measured. Results:For the level of center of resistance(LC), there was statistically significant decrease of alveolar bone on lingual aspect (0.78?0.77) mm and no change on labial aspect, as the center of resistance(CR) was retracted lingually by (-3.02?1.13) mm during treatment. Analogous changes were found at the level of 3 mm apical to the center of resistance (L3C). In retention stage, with stable positioned lower incisor, no statistically significant change of alveolar bone was found on labial aspect at LC while a little amount of decrease of labial bone (0.20?0.58) mm was found at L3C. On the contrary, subsequential bone apposition could be detected with increase of lingual bone at both levels by (0.31?0.76) mm and (0.38?0.94)mm respectively. Conclusion:Speed of labial bone resorption is faster than that of lingual bone apposition during orthodontic treatment. In retention stage, sequential bone apposition on lingual aspect is presented with lower incisor in stable position.

BACKGROUND:The traditional treatment for thoracolumbar vertebral fractures is posterior short-segment pedicle screw fixation. This method uses vertebral soft tissue stretch through distraction reduction mechanism, makes shift bone reset, and restores shape and height of vertebral body. Long-term folow-up found that part of cases experience complications such as vertebral height loss, loss of spinal correction of Cobb angle, the pedicle screw breakage and loosening. OBJECTIVE:To explore clinical effects of pedicle screw fixation combined with the implantation of artificial bone composite for the treatment of thoracolumbar fractures, and to compare with conventional pedicle screw. METHODS: A total of 80 patients with thoracolumbar fractures, who were treated in the Yantaishan Hospital from March 2011 to May 2014, were randomly divided into two groups. In the experimental group, patients received pedicle screw fixation combined with the implantation of artificial bone composite. In the control group, patients received routine pedicle fixation. Pain visual analog scale score was evaluated before treatment and at 6 months after treatment in patients of both groups, and easement of pain was evaluated after treatment. Vertebral body height (normal anterior flange height and up and down the front cone height and the ratio of the average multiplied by 100%) and sagittal Cobb angle (sagittal measurements of X-ray film) were measured in patients of both groups before treatment and at 1 and 12 months after treatment. According to conventional hierarchical evaluation criteria used al over the world, prognosis was assessed at 6 months after treatment, including basic cure, powerfuly, effectively, and invalid. RESULTS AND CONCLUSION: At 6 months after treatment, significant differences in pain visual analog scale scores were detected in the experimental group (2.4 points) and control group (3.7 points) (P < 0.05). No significant difference in height of the injured vertebra and Cobb angle was detected between the two groups before treatment (P> 0.05). The height of the injured vertebra and Cobb angle were better in the experimental group compared with the control group at 1 and 12 months after treatment (P < 0.05). Significant differences in treatment efficiency were detectable between the experimental group (90%) and the control group (73%) at 6 months after treatment (P < 0.05). These data indicate that pedicle screw fixation combined with the implantation of artificial bone composite in the treatment of thoracolumbar fractures can be used to fix fracture reduction, effectively restore height of injured vertebral body, prevent postoperative Cobb angle loss, and improve the treatment efficiency.

Objective To observe the ultrastructure and absorption function of colon mucosa in rat with ultra-short bowel syndrome. Methods Totally 30 SD rats were randomly divided into three groups: ultra-short bowel group (90%-95% of the intestine was surgically resected, n = 10), sham group (n = 10), and normal control group (n = 10). All animals were given with enteral nutrition. Scanning electron microscopy was performed 21 days later to observe the morphology of mucosal surface, and transmission electron microscopy was performed to observe the ultrastructural changes of intestinal epithelial cells. The absorption of colon to water, carbohydrates, and amino acid determined after 3 hours of closed perfusion of the colon with D-xylose solution and 15N-glycine on the continuous cycle of colon. Results As shown by the transmission electron microscopy, compared with the normal control group, rats in the ultra-short bowel group showed significantly decreased goblet cells on colonic mucosl surface, increased epithelial cells, longer and denser microvillus, increased area of membrane surface, increased number of cell-cell junctions, increased number of desmosome, tight junction, and gap junctions, higher development of endoplasmic reticulum and dictyosome, and increased number of mitochondria. As shown in the screening electron microscopy, compared with the normal rats, rats in the ultra-short bowl group had significantly deeper colon folds, thicker mucous membrane, increased number of bay openings, and longer and denser microvillus-like structures inside bays. The capability of water absorption was signicatnly higher in the ultra-short bowl group than in the sham group and normal control group (P = 0. 000) . The absorption rates of xylose and 15 N-glycine were also significantly higher in the ultra-short bowl group than in the control group (P < 0. 01). Conclusions The absorption capability can be compensatively increased in rats with ultra-short bowel syndrome. Decreased apoptosis of colon mucosa cells, increased absorption cells, hyperplasia of microvilli, increased area of the membrane surface,and increased number of mitochondria may constitute its material and energy bases.

Objective To evaluate the clinical significance of plasma ionized calcium (ICa) and total calcium (TCa) measurement in diagnosis of tumor-associated hypercalcemia. Methods The heparin lithium anticoagulated plasma were collected and measured with ion selective electrode (ISE) and orthocresolphthalein complexone (OCPC) method for ICa and TCa in 77 patients with malignant tumor (tumor group) and 44 healthy controls (control group). Meanwhile,plasma albumin and pH value were measured to correct TCa (cTCa) and ICa(nICa). The results were analyzed. Results The levels of cTCa,ICa and nICa in tumor group were significantly higher than those in control group(P< 0.01 ) ,but there was no significant difference of TCa between two groups (P > 0.05 ). cTCa > 2.70 mmol/L, nICa > 1.35 mmol/L as the hypercalcemia eritical value, the positive rate of nICa and cTCa were 18.18% (14/77) and 6.49% (5/77)respectively,the difference was significant (P = 0.023). Conclusion Determination of ICa may be more clinical meaningful than TCa for tumor-associated hypercalcemia.
