BACKGROUND: The aseptic loosening of prosthesis has become one of the most obvious matters after operation of prosthesis replacement. OBJECTIVE: To verify the effect of ibandronate on early fixation of implants by local application. METHODS: Forty-four Zelanian rabbits were used in the experiment. A standard animal model of the rabbits' both tibia was embedded with metal screw into the proximal end. Ibandronate at 1 mg/L was sprinkled locally in the left tibia of every rabbit (experimental group), while saline solution was given in the right tibia (control group). (P < 0.001). These findings indicate that, local application of ibandronate solution can obviously promote new bone formation at the earlier period, improve early fixation of implants and decrease the incidence of aseptic loosening of prosthesis.

Objective To investigate the clinical results and related key points of surgical treatment for Hawkins Ⅲ talus neck fractures.Methods From March 2005 to March 2010,26 patients with Hawkins Ⅲ talus neck fracture were treated and 21 of them were followed,including 13 males and 8 females,with an average age of 37.6 years.The fractures occurred on the left side in 11 patients and on the right side in 10patients.The mechanism of injury included high falling injury in 13 patients,traffic accident injury in 7 patients and rolling down injury in 1 patient.Five cases were closed fractures and 6 cases were open fractures.A bilateral approach,the medial and lateral approaches,was used to perform the operation with cannulated screw fixation in emergency.After external fixation in functional position for 6 weeks without loading,ankle joints were allowed to take exercise with hinge brace and to bear partially basing on plain radiograph 12-16weeks later.The weight-bearing should be adjusted with follow-up.Functional results were assessed according to AOFAS (American Orthupaedic Foot and Ankle Society,AOFAS)score.Results The average duration of follow-up was 36.6 months (range,6-60 months).All fractures gained union and the average union time was 4.5 months.The average AOFAS score was 78.6.There were 4 cases in excellent results,10 in good,5 in fair and 2 in poor.The overall excellent and good rate was 67.8%.Traumatic arthritis occurred in 13 cases and avascular necrosis in 5 cases.Conclusion The effect of surgical treatment for Hawkins Ⅲtalus neck fracture via a bilateral approach is satisfactory.

Objective To compare the effect of postoperative intercostal nerves cryoanalgesia and patient controlled epidural analgesia (PCEA) in patients undergoing thoracic surgery. Methods From April 2006 to May 2008,89 patients undergoing thoracic surgery were randomly divided into intercostal nerves cryoanalgesia group (group A,47 cases) and PCEA group (group B,42 cases). The scores of pain, use of pain medication and time of out-of-bed activity after the operation were used to evaluate the effect of pain between two groups. Results The scores of pain in group A and group B were (1.49 ± 0.80) and (2.43 ± 1.21) scores respectively. There were significant differences in the scores of pain. The use of pain medication [(1.28 ± 0.62) times vs (2.02 ± 1.05) times]and time of out-of-bed activity after the operation [(43.15 ± 12.22) h vs (64.10 ± 14.25) hi were significant difference between the two groups(P< 0.05). Conclusions For reducing the post- thoracotomy pain,intercostal nerves cryoanalgesia is superior to PCEA. Intercostal nerves cryoanalgesia can provide satisfactory analgesia after thoracic surgery.

Objective The aim of this study was to evaluate the efficacy and safety of the approach of the Nuss procedure for the correction of pectus excavatum in children without thoracoscopy.Methods From Oct 2007 and May 2009,48 patients with pectus excavatum underwent Nuss procedure.Among them 22 were done under the thoracoscopic guidance,and the other 26 in a non-thoracoscopic way,in which,a bilateral extrapleural tunnel to the edge of sternum was created using a blunt dissection via a bilateral thoracic skin incision.Without introducing the thoracoscopy into the thoracic cavity,a steel bar was inserted in the entirely extrapleural tunnel and turned as the standard Nuss procedure.Results All 48 patients recovered uneventfully.There were no postoperative deaths and serious complications.A single alloy steel bar(23-40 cm)was used in all patients.In the non-video-assisted extrapleural group(n=26),no pneumothorax occurred,the operating time(after anesthesia)ranged from 24~38 minutes[mean(25.4±2.6)mins],blood loss was minimal(range,5-10 ml),and the hospital stay was ranged from 3-6 days[mean(4.5±1.1)days].In the thoracoscopic group(n=22),the corresponding figures were 40 to 60 minutes[mean(53.5±3.4)mins)],10 to 15ml,5-8days[mean(7.0±2.2)days],respectively.No recurrent of the funnel chest occurred during the 3-18 months(median 10.4 monthes)of follow-up.The bar displacement occurred in 1 case 2 months after operation,which was replaced with satisfied result.Conclusion The non-thoracoscopic approach of the Nuss procedure is a safe and less traumatic procedure for the correction of pectus excavatum.

Objective:
To analyze the clinical value of SPECT/CT in diagnosis of skull base bone invasion and clinical decision-making for nasopharyngeal carcinoma (NPC), and to compare their diagnostic value with SPECT/CT, CT, MRI, and MRI combined with SPECT (MRI-SPECT) for skull base bone invasion.
Methods:
Before treatment, among 348 newly diagnosed NPC patients, CT scan was performed in 186 patients (group A) and the remaining 162 patients received MRI scan (group B). Clinical doctors then made clinical management decisions according to the CT or MRI results. After that, all patients underwent 99Tcm-MDP SPECT/CT examination for nasopharyngeal local tomography, and the results were provided to the clinical doctors to make clinical management decisions again. The changes between the two clinical management decisions were scored according to diagnosis, range of lesion, staging, treatment regimens, and auxiliary examination. The diagnostic value of CT scan, MRI scan, SPECT/CT and MRI-SPECT for skull base bone invasion was then evaluated and compared.
Results:
In terms of changes in scores of clinical management decisions, the score of group A was 1.387 and group B was 0.951, showing a significant difference between the two groups by Wilcoxon test (

Objective:
To study the current situation and relevant risk factors for disability and dementia among the elderly in urban areas of Jiangsu province.
Methods:
A stratified cluster sampling method was used to select representative elderly people aged 60 years and over in urban areas in Jiangsu Province, and a face-to-face questionnaire survey was conducted.The activities of daily living(ADL)scale and mini-mental state examination(MMSE)were used to assess the status of disability and dementia.And the relevant risk factors for disability and dementia were analyzed by univariate and multivariate Logistic regression methods.
Results:
A total of 1 600 elderly people were investigated and 1 514 valid questionnaires were recovered.The effective recovery rate was 94.6%.The rates of disability and dementia were 17.9%(271/1 514)and 8.5%(129/1 514)respectively in the elderly in Jiangsu urban areas.Univariate analysis showed that age, marital status, education level, empty-nest, whether or not to suffer from chronic diseases, health status, medication, and whether or not to have dementia were significantly related with the disability in the elderly(

Burning mouth syndrome (BMS) is a chronic oral and facial pain disorder characterized by burning pain in the oral mucosa, with multiple pathogenic factors including psychosocial, neuropathological, endocrine, and immune factors. There is still a lack of effective treatment options that have been demonstrated to work. With the development of research on the pathogenesis and treatment of BMS, multidisciplinary comprehensive treatment has gradually been introduced and become a new trend of diagnosis and treatment. Before multidisciplinary treatment, it is necessary to go through a full and comprehensive diagnosis and analysis, select the best comprehensive treatment plan, take the diagnosis and treatment of stomatology as the basis and premise, and apply other multidisciplinary combined treatment, including the treatment of concurrent diseases, psychological interventions, correction of bad habits, etc. A combination of laser therapy and psychological intervention is a more effective treatment method among the current treatment methods, with high comfort and good acceptance by patients. If necessary, mecobalamin tablets, clonazepam α-lipoic acid and other drugs can be used to nourish nerves and provide symptomatic treatment. The comprehensive multidisciplinary treatment of BMS is expected to become a new trend and provide a new strategy for improving the therapeutic effect.
