In order to strengthen the stomatology experiment teaching,mehods such as constructing the stomatology experimental teaching platform,improving teaching methods and reforming the system of exam and assessment were adopted.Through these measures,opration and the innovative ideology of students were obviousely enhanced,students' interest were estimulated,the innovative spirit was enlightened and the comprehensive potential ability was developed.

OBJECTIVE: Lumbar spine stenosis (LSS) can result in symptomatic compression of the neural elements, requiring surgical treatment if conservative management fails. Minimally invasive surgery has come to be more commonly used for the treatment of LSS. The current study describes outcomes of bilateral microdecompression by unilateral or bilateral laminotomy (BML) for degenerative LSS after a minimum follow-up period of 3 years and investigates factors that result in a poor outcome. METHODS: Twenty-one patients who were followed-up for at least 3 years were included in this study. For clinical evaluation, the Japanese Orthopedic Association (JOA) scoring system for low back pain was used. The modified grading system of Finneson and Cooper was used for outcome assessment. Radiographic evaluation was also performed for spondylolisthesis, sagittal rotation angle, and disc height. RESULTS: Twenty-one patients (10 men, 11 women) aged 53-82 years (64.1+/-8.9 years) were followed-up for a minimum of 3 years (36-69 months). During follow-up, two patients underwent reoperation. Average preoperative JOA score and clinical symptoms, except persistent low back pain, improved significantly at the latest follow-up. There were no significant differences in radiological findings preoperatively and postoperatively. Thirteen patients (61.9%) had excellent to fair outcomes. CONCLUSION: BML resulted in a favorable and persistent outcome for patients with degenerative LSS without radiological instability over a mid-term follow-up period. Persistent low back pain unrelated to postoperative instability adversely affects mid-term outcomes.

OBJECTIVE: Progression after operation in traumatic brain injury (TBI) is often correlated with morbidity and poor outcome. We have investigated to characterize the natural course of traumatic intracranial hemorrhage and to identify the risk factors for postoperative progression in TBI. METHODS: 36 patients requiring reoperation due to hemorrhagic progression following surgery for traumatic intracranial hemorrhage were identified in a retrospective review of 335 patients treated at our hospital between 2001 and 2010. We reviewed the age, sex, Glasgow Coma Scale, the amount of hemorrhage, the type of hemorrhage, rebleeding site, coagulation profiles, and so on. Univariate statistics were used to examine the relationship between the risk factors and reoperation. RESULTS: Acute subdural hematoma was the most common initial lesion requiring reoperation. Most patients had a reoperation within 24-48 hours after operation. Peri-lesional edema (p=0.002), and initial volume of hematoma (p=0.013) were the possible factors of hemorrhagic progression requiring reoperation. But preoperative coagulopathy was not risk factor of hemorrhagic progression requiring reoperation. CONCLUSION: Peri-lesional edema and initial volume of hematoma were the statistical significant factors requiring reoperation. Close observation with prompt management is needed to improve the outcome even in patient without coagulopathy.

OBJECTIVE: The aim of this study is to investigate the factors that may be related to bone graft infection and to contribute to lower the infection rate. According to current studies, the rate of bone graft infection after cranioplasty was reported up to 15.9% and this is significantly high. There are many analyses of the factors influencing bone graft infection, but this issue may need to be reconsidered in that the current medical environment is ever-changing. METHODS: We retrospectively reviewed the demographic, clinical data of 130 patients who underwent cranioplasty following decompressive craniectomy from January 2004 to December 2011. We analyzed several factors influencing bone graft infection and divided them into three categories of clinical, operation-related and hematological factors including white blood cell count, erythrocyte sedimentation rate, C-reactive protein and albumin. Statistical significance was done by chi-square test, Fisher's test and Mann-Whitney U test. RESULTS: The infection occurred in 12 patients in 130 cranioplasties (9.2%). There was no difference in infection rate between each group of early and later surgery, graft material, cause of craniectomy. Among many factors, low Glasgow Coma Scale (GCS< or =8) and combined ventriculoperitoneal (VP) shunt were significantly correlated with bone graft infection (p=0.025, p=0.025, respectively). There was no statistically significant difference in hematological analysis between groups. CONCLUSION: Low GCS and combined VP shunt with cranioplasty may increase the risk of bone graft infection.

OBJECTIVETo explore the risk factors, and control measures of cytomegalovirus (CMV) infection after hematopoietic stem cell transplantion (HSCT) in children with primary immunodeficiency diseases(PID).

METHODSWe retrospectively analyzed results of 26 patients with PID-Wiskott-Aldrich syndrome (WAS, n=20), severe combined immunodeficiency (SCID, n=1) , X-linked chronic granulomatous disease (XCGD, n=2) and X-linked hyper-immunoglobulin M (IgM) syndrome (XHIM, n=3)-who underwent HSCT from June 2007 to December 2012 in our center. Serologic studies (ELISA) and weekly CMV infection surveillance (quantitative PCR, qPCR) were routinely performed before and after HSCT. Ganciclovir or forcarnet was used for pre-emptive and curative therapy.

RESULTSAll 26 patients were male with the median age at HSCT of 27 months (range 7-77 months). At a median follow up of 24 months (range 5-66 months), the 5-year overall survival rate was (75.0 ± 9.0) %. CMV infection occurred in 42.3% (11 of 26) of the patients, two of them developed CMV interstitial pneumonia (CMVIP). Univariate analysis revealed that the incidence of pre-transplant CMV infection between with and without CMV activation groups after HSCT was significantly different (62.5% vs 10.0%, P=0.010). Additional variables not associated with CMV infection were stem-cell sources, donor type, HLA disparity and acute GVHD (all P values>0.05).

CONCLUSIONCMV infection was a major complication of HSCT. Sensitive monitoring, early diagnosis, timely treatment may improve the survival rate for these PID undergoing HSCT.
