BACKGROUND: Tooth intrusion easily leads to root resorption. Previous studies regarding orthodontic treatment-caused tooth root resorption or retrospective clinical studies based on X-ray films have great errors in outcome evaluation because of intrusion force which cannot be precisely controlled. OBJECTIVE: This study established dog models of mini-implant anchorage for incisor intrusion to observe the histological changes of tooth root and periodontal tissue and to evaluate the feasibility and safety of mini-implant anchorage for incisor intrusion. METHODS: Nine dogs were assigned to one control group (n = 1) and four experimental groups per time to sacrifice (1, 2, 4 and 12 weeks; n = 2 dogs for each experimental group). No force was added to the control group. In the experimental groups, mini-implant as an anchorage was placed in the buccal alveoli between maxillary second and third incisors on each side. A traction force of 100 g was imposed to each side to intrude the maxillary first and second incisors on each side. At 1, 2, 3, and 4 weeks (traction force was imposed for 4 weeks and after withdrawal of extraction force, mini-implant was retained in place for 8 weeks), dogs were sacrificed. The first and second incisors together with gingival and alveolar bone were completely resected to prepare histological specimens. Following hematoxylin-eosin staining, histological changes of tooth root and periodontal tissue were observed. RESULTS AND CONCLUSION: Compared with the control group, in the 1-week group, histological changes were primarily at the root tip and alveolar ridge crest, alveolar bone and cementum were absorbed and peridental membrane presented glassy degeneration in local region; in the 2-week group, bone resorption degree and range were obviously enlarged, and bone resorption developed from root tip, root middle part to cervical part; in the 4-week group, bone resorption was still active and the glassy degeneration of peridental membrane disappeared; in the 12-week group, significant improvement in alveolar bone and cemental surface was observed, bone lacuna had deposition of newly formed bone, and peridental membrane was orderly arranged. These findings reveal that in the mini-implant anchorage for dog incisor intrusion, early histological changes primarily appear in the root tip and alveolar ridge crest, presenting as alveolar bone and cemental resorption and the glassy degeneration of the peridental membrane. Bone resorption extent and range expand with the persistence of traction force. After withdrawal of traction force, tooth root and periodontal tissue were gradually repaired

Objective To evaluate the function of peripheral vessels, the change of ankle-brachial Index (ABI) and toe-brachial Index (TBI), and its related risk factors in elderly type 2 diabetic patients were observed. Methods Doppler frequency spectrum was used on lower limb of 128 type 2 diabetic patients and 103 non-diabetic people. ABI and TBI were calculated, other indexes including body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), hypersensitivity C-reactive protein(hs-CRP), triglyceride (TG), total cholesterol (TC), high density lipopretein (HDL), low density lipoprotein (LDL), fasting blood glucose(FBG), postprandial blood glucose (PPBG) and glycosylated hemoglobin (HbAlC) were measured. Results ABI and TBI were decreased in T2DM group as compared with control group (P<0.05), and hs-CRP was increased in T2DM group. With multiple stepwise regression, it showed that ABI and TBI was negatively related with age, SBP and T2DM duration, while ABI was positively correlated with HDL. In multiple logistic regression, cigarette, age, high blood pressure(HBP) and T2DM duration were independent risk factors with respective odds ratios of 1.94 (P<0.05), 2.12(P<0.01), 2.74(P<0.05) and 1.59(P<0.05), respectively. Conclusion Older age, T2DM duration, ciga-rette, hyperglycosema, HBP, low HDL and high bs-CRP play important roles in the occurrence and development of peripheral vascular dis-ease (PVD) in elderly type 2 diabetic patients. PVD of type 2 diabetic patients can be found earlier with Doppler diagnostic instrument.

Objective To explore the effect of the clinical case oriented management model on nurses comprehensive ability, psychological and critical mind. Methods In 2014 on the implementation ofroutine clinical case management modelas the control group, collected 97 cases of clinical cases. In 2015 on the implementation ofthe clinical case oriented management modelas the observation group, collected 110 cases of clinical cases. Compared two methods of management to improve the nurse management theoretical knowledge, clinical practice ability and deal with the size of the case skills help. When/after clinical special case found the influence for nurses, including psychology, work in the nursing work will, enthusiasm, independent ability to deal with related cases and the nurse critical thinking ability, etc. Results The proportion of the nurses thought that it was helpful to improve the management of theoretical knowledge, clinical practice ability and deal with the size of the case skills and the case analysis of satisfaction were 98.79%(244/247), 99.19%(245/247), 98.79%(244/247), 99.60%(246/247) in the observation group, and 88.57%(217/245), 87.35%(214/245), 87.76%(215/245), 90.61%(222/245) in the control group. The differences were statistically significant (χ2=21.390-27.571, P < 0.01). The proportion of the nurse considered that special case on the psychological effects of nursing work, engaged in the willingness and enthusiasm were the main factor were 15.79%(39/247), 13.77%(34/247), 11.34%(28/247) in the observation group, and 31.84%(78/245), 31.02%(76/245), 30.61%(75/245) in the control group. The differences were statistically significant (χ2=17.475, 21.097, 27.611, P < 0.01). After special case, the percentage of nurses to independently handle the case, help others, loss rates were 97.57%(241/247), 2.02% (5/247), 0.40% (1/247) in the observation group, and 85.71% (210/245), 12.24% (30/245), 2.04% (5/245) in the control group. The proportion of nurses to independently handle the case in the observation group was higher than that in the control group, but the ratio of nurses to help others, loss rates in the observation group were lower than those in the control group, the differences were statistically significant (χ2=22.647, P<0.01).Critical thinking score, the observation group of nurses in the search for truth, open mind, analytical ability, system organization, judging thinking self-confidence, curiosity, cognitive maturity, such as total score were respectively (43.24±4.01), (43.03±4.12), (47.66±4.23), (44.21± 3.92), (44.00 ± 4.97), (52.13 ± 4.44), (48.23 ± 4.85), (319 ± 14.57) points. The control group nurses were respectively (39.00±3.56), (38.90±3.28), (43.65±2.47), (40.55±1.99), (39.00±3.40), (47.87±4.01), (41.89± 5.11), (292.23 ± 6.02) points. The differences were statistically significant(t =12.15-24.19, P < 0.01). Conclusions The clinical case oriented management model can improve nurses comprehensive ability, reduce the adverse impact of the special case for nurses, improve the clinical nurses' critical thinking ability, to ensure patient safety.
