??Teeth fractures include crown fracture?? root fracture and crown-root fracture. If the tooth fragment is available?? it can be bonded to the tooth. In young patients with immature?? still developing teeth?? it is advantageous to preserve pulp vitality by pulp capping or partial pulpotomy. Also?? this treatment is the choice in young patients with completely formed teeth. If displaced?? reposition the coronal segment of the tooth as soon as possible. As an emergency treatment a temporary stabilization of the loose segment to adjacent teeth can be performed. Sequential therapy for traumatized teeth with mid-root fracture or cervical third fracture or crown-root fracture could preserve the coronal fragment.

??Objective    To study the effect of different concentrations of ozone water on the expression of IL-6 in periodontal tissues of rat with periodontitis. Methods    A total of 70 male Wistar rats weighing??200 ± 20??g were chosen??randomly select five as normal control group??executed by cervical dislocation method????and the rest of the rats were made model of periodontitis. When the model was established??five periodontitis rats were randomly selected as no-treatment group??executed by cervical dislocation method??. The rest of periodontitis rats were randomly divided into ozone water treatment group and control treatment group for periodontal pocket rinsing. The general conditions and pathological changes of the periodontal tissues were observed. Immunohistochemical staining was conducted to determine the expression of IL-6 in the periodontal tissues. Results    The level of IL-6 in periodontal tissues of rats of no-treatment group was much higher than that in the normal control group??P < 0.05??. The level of IL-6 in the treatment groups was much lower than that in the no-treatment group??P < 0.05??. In each period of rinsing??at 15mg/L of ozone water treatment group??the expression of IL-6 in periodontal tissue was lower than that in other concentration groups ??5mg/L??10mg/L????P < 0.05????but there was no significant difference compared with the control treatment group. Conclusion    The ozone water can reduce the IL-6 level in periodontal tissues in rats and the effect is more obvious in concentration of 15mg/L??which has certain treatment effect on periodontitis.

Abstract Objective To observe the long-term outcomes of laparoscopic subtotal colectomy with antiperistaltic cecorectal anastomosis (LSCACRA) in treating slow transit constipation (STC). Methods The clinical data of 40 patients with STC underwent LSCACRA between April 2007 and December 2009 in the 150th Central Hospital of PLA were analyzed retrospectively. The operation time, operation blood loss, first flatus time, hospital stay time and complications were analyzed. Preoperative and postoperative parameters of patients at 3rd, 6th, 12th, and 24th month were collected, including the Wexner constipation scale (WCS), gastrointestinal quality of life index (GIQLI). Results Laparoscopic operation was undertaken to all the patients without converting to open operation. There were two cases of incomplete ileus and two cases of pulmonary infection with Dindo>??. Comparing with the preoperative values, the values of WCS,GIQLI,AFIS and ABS at 3rd, 6th, 12th and 24th month after operation improved significantly (P<0.001). APIS didn't improve at 3rd and 6th month after operation comparing with the preoperative value (P>0.05), while the results at 12th and 24th improved significantly (P<0.05). Conclusion LSCACRA is a safe and effective operation method, which has a significant effect in the treatment of STC and notably relieves symptoms, nutritional status and quality of life of patients, presenting small wounds and faster recovery.

Abstract Objective To investigate factors associated with postoperative complications after laparoscopic-assisted radical rectal surgery in rectal cancer. Methods The clinical data of 305 patients with rectal cancer performed laparoscopic-assisted radical resection from April 2008 to April 2012 in Affiliated Tumor Hospital of Xinjiang Medical University were analyzed retrospectively. All the data were analyzed by the t test??chi-square test??Fisher exact probability or Logistic regression model. Results Postoperative complication occurred in 76 patients (24.9%). On univariate analysis, postoperative complication was associate with gender??age??preoperative comorbidity??location of tumor??TNM staging??neoadjuvant chemoradiotherapy??operative time and surgeon experience??P??0.05??. Logistic regression analysis revealed that gender??preoperative comorbidity??location of tumor??TNM staging and surgeon experience were independent risk factors for postoperative complications??P??0.05??. Follow up was available in 275 patients (90.2%) with a median follow up of 24 months??rang??2-48months??. Differences in survival and recurrence rate between patients with and without postoperative complication were of no statistical significance ??P >0.05??. Conclusion Gender??preoperative comorbidity??location of tumor??TNM staging??surgeon experience were independent risk factors for postoperative complications in laparoscopic-assisted radical rectal surgery in rectal cancer.
