Objective To compare the orthodontic efficacy of the self-locking appliance and the ordinary straight wire appliance.Methods A total of 144 patients from March 2010 to March 2012 at the Department of Stomatology Orthodontic Surgery,Zhejiang Dongyang City People's Hospital were divided into observation group (n =72) and control group (n =72) according to the random number table.The observation group were treated with the self-locking appliance,and the control group were treated with the ordinary straight wire appliance.Results (1) The number of referral unconventional visits had no statistically significant difference between two groups (U =-1.65,P =0.0990).The number of routine visits of observation group was significantly less than that of the control group (U =-2.80,P =0.0052).(2) The VAS score of observation group was significantly lower than that of the control group (U =-8.47,P =0.0000).Conclusions The orthodontic efficacy of the self-locking appliance is obviously better than the ordinary straight wire appliance,and the former-caused pain is lighter.Therefore,the self-locking appliance is more suitable for orthodontic surgery.

Background and purpose:How to predict the survival length for terminally cancer patients is very important, it will help families and physicians to make decisions. This study aimed to reveal the factors related to the survival time of terminally ill cancer patients who received palliative care in our hospital. Methods:The clinical data of 271 dead patients treated in the Department of Palliative Care, Fudan University Shanghai Cancer Center from Mar. 2007 to Mar. 2012 were analyzed. The Kaplan-Meier method and the log-rank test were used to determine the corresponding factors with survival. Cox regression model was used to examine the independent prognostic factors. Different survival length of groups divided by different prognostic indexes was compared by log-rank test. Results:Seven factors were found to be related with the survival according to univariate analysis. The related factors were Karnofsky performance score (P<0.001), dyspnea (P=0.037), delirium (P=0.015), high white blood cell count (P=0.012), low lymphocyte percentage (P=0.030), high lactate dehydrogenase (P<0.001) and low serum albumin (P=0.001). The multivariate analysis selected four independent factors:Karnofsky performance score<30, high lactate dehydrogenase, low serum albumin and delirium.Conclusion:The study shows the clinical survival prognostics with Chinese characteristics. The combination of the seven factors may be useful but more studies in this area deserve further investigated.

砄bjective:To study the effects of superlong pedicled latissimus dorsi muscle transplantation (SPLDMT) in the treatment of facial paralysis.Method: 16 cases of unilateral long standing facial paralysis were treated with SPLDMT in 1991～1998;follow up was conducted and the effects were analysed. Results:After operation satisfied movement recovery of the facial muscles was observed in 12 and improvenent in 3 of the 16 patients,no change was found in only 1 case. Conclusion: SPLDMT is effective in the treatment of unilateral long standing facial paralysis.

BACKGROUND:In recent years,bone defect caused by tumor,trauma,infection and so on is always the troublesome problem in the orthopaedics field. Many kinds of bone graft substitute have been exploited to conquer this problem.OsteoSet,a new substitute for bone graft,with the advantage of excellent biocompatibility,degradation,bone conduction and induction of ossification,is an ideal product.OBJECTIVE:To investigate the effect of OsteoSet in repairing bone defects due to tumor.DESIGN:Retrospective study and case analysis.SETTING:Department of Orthopaedics,First Hospital of Jilin University.PARTICIPANTS: Twenty-two patients with bone defect caused by bone tumor who received operation in the Department of Orthopaedics,First Hospital, Jilin University between June 2004 and September 2006.The involved patients,14 male and 8 female,averaged 23 years old ranging from 5 to 68 years.Inclusive criteria:① Diagnosed as benign tumor in bone according to the bone tumor classification criteria instituted in China in 1983.②Had the indications of tumorectomy and bone grafting with OsteoSet substitute.③Informed consent was obtained.The position of tumor was described as 6 in shaft of humerus,2 in neck of femur, 9 in inferior segment of femor, 4 in superior segment of tibia and 1 in celcaneus respectively.METHODS:①Operation procedure:After the effective anesthesia,the tumor was exposed as usual.Then the tumor was resected as thoroughly as we could.When OsteoSet substitute in the bone defect was filled carefully in order to avoid crushing into pieces.At last the substitute should be covered with periosteum or soft tissue.②Postoperative evaluation: The area of substitute absorption was observed by X-ray examination in 4, 8, 12 and 24 weeks after oporation.Postoperatively.incision healing,pain and complications of paients were observed at 6,7,8 and 9 months.MAIN OUTCOME MEASURES: OsteoSet substitute absorption rate and new bone formation rate as well as postoperative follow-up results.RESULTS:Twenty-two patients were involved in the final analysis.①OsteoSet substitute absorption rate and new bone formation rate:The evident absorption of OsteoSet substitute could be found in the X-ray film 4 weeks after operation.At the same time,the slender bone trabecula formed and bone density ncreased.At the end of 12 weeks after operation,about 97.1 percent OsteoSet substitute was absorbed and approximate 95.3 percent new bone infiltrated the defect area. In the 6 months, the substitute absorption rate and the new bone formation rate were 99.1 percent and 98.6 percent respectively. Stable bone trabecula formed in the bone defect area and the new bone connected with the surrounding health bone naturally by remolding.②Follow-up results:All the operative incisions healed well and there were no pain and discomfort in the duration of hospital stay; All the patients had no fever, erythra or other allergic responses during the follow up;The OsteoSet substitute were absorbed well and new bone also formed well in all the cases;All the patients were satisfied with the recovery of limb function.CONCLUSION:The substitute absorption was accordance with the new bone formation.For its good absorption and new bone reconstruction,OsteoSet is an ideal substitute for bone defect caused by tumor.

Objective To analyze the evaluation value of ABCD2 combined with carotid ultrasound on the prediction of cerebral infarction after transient ischemic attack. Methods The clinical data of 133 patients with TIA admitted from July 2014 to December 2015 were analyzed. We score patients according to the standard of ABCD2 score and carotid ultrasound. The incidence of cerebral infarction within 7 days was observed. Results In the 133 TIA patients 35(26.3%) progressed to cerebral infarction. The 7-day incidence of cerebral infarction was 7.1% in patients with an ABCD2 score of low risk (0-3), 25% with a score of moderate risk(4-5), and 40% with a score of high risk(6-7). The difference of the incidence of cerebral infarction was significant between the low and moderate risk stratification (P < 0.05). The 7-day incidence of cerebral infarction was 39.5% in patients with carotid plaque and 75.0% in patients with carotid stenosis , both higher than the control group (P < 0.05). In the ABCD2 score ≥4 group, the incidence of cerebral infarction in the patients with abnormal carotid ultrasound was 38.4% ,significantly higher than the patients with normal carotid ultrasound (P < 0.05). Conclusions The ABCD2 score is effective to predict short-term risk of cerebral infarction in the patients with TIA. Combination with carotid ultrasound can improve the predictive accuracy of 7- day risk of cerebral infarction after TIA.

Objective For the purpose of exploring the influence exerued by the amount of template DNA on the results of automatic fluerescent detection. Method For the purpose of buiding the optimal amount of template DNA amplified, we have analyzed different amount of template DNA (9947A) by 3100 Genetic Analyzer with the multiplexing Profiler Plus Kit. Results The optimal amounts of template DNA amplified were between 0.31ng and 2. 5ng by using 3100 Genetic Analyzer. Conclusion It will produce the incorrect analytic results if the amounts of template DNA were too high or too low.
