BACKGROUND: More and more patients with periodontal disease require orthodontic treatments. Thus, the remodeling process and its mechanism of inflammatory periodontal tissues become a hot point during orthodontic tooth movement.OBJECTIVE: To observe the remodeling of inflammatory periodontal tissues during orthodontic tooth movement.METHODS: A total of 50 Sprague Dawley rats were randomly divided into the control and periodontitis groups. In the periodontitis group, rats were established periodontitis models. After that, all rats were prepared for orthodontic tooth movement models. The remodeling of periodontal tissues was observed by hematoxylin-eosin staining at 1, 3, 5, 7 and 14 days after orthodontic tooth movement.RESULTS AND CONCLUSION: The movement distance of the periodontitis group was greater than that of the control group. At 0-7 days after orthodontic force application, there was obviously bone resorption at the pressure side and the bone formation was inhibited at the tension side; at 14 days after force application, the bone resorption was diminished, associated with large numbers of multinucleated osteoclasts at the pressure sides in both groups. The findings showed that rats with periodontitis suffered more periodontal traumatism during orthodontic tooth movement, thus, treatment should be delayed until the inflammatory signs were controlled and the local inflammatory was eliminated.

Objective To evaluate the efficacy of laparuseopic and open D_2 radical gastrectomy for gastric cancer. Methods From January 2008 to February 2009, 64 gastric cancer patients received laparoscopic radical gastrectomy (LAP group) and 60 gastric cancer patients received open gastrectomy (open group) at Changzhou No. 2 People's Hospital. Clinical parameters including operation time, blood loss, resection margin of gastric cancer, number of lymph nodes dissected, time for passage of flatus, time for out-of-bed activity, hospital stay and postoperative complications in the 2 groups were analyzed via t test and chi-square test. Results Gastrectomy was successfully performed on all patients. Mean operation time in LAP group was significantly longer than open group (t=5.56, P<0.05). There was no significant difference in the length of resection margin and number of lymph nodes dissected between the 2 groups (t=0.67, 0.86, 1.09, P>0.05). The mean blood loss, time for passage of flatus, time for out-of-bed activity and hospital stay in LAP group were significantly lesser than in open group (t=4.59, 5.56, 16.39, 4.79, P<0.05). Six patients in LAP group and 5 patients in open group had compli-cations postoperatively. All patients were followed up for 1-13 months, and no recurrence or death occurred. Conclusion Laparoscopic D_2 radical gastrectomy is safe and effective for gastric cancer.

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3~5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.
