Today pedicle screw instrumentation system and short-segment fixation have been commonly used for treatment of thoracolumbar burst fractures because pedicle screw fixation allows 3-column fixation and facilitates simultaneous application of axial compression or distraction and rotational forces.Indirect decompression and direct decompression are the two ways to deal with canal compromise when pedicle screw instrumentation is used.Indirect decompression is achieved to correct the canal compromise due to ligamentotaxis and hyperextension.The present study reviews the current research on indirect spinal canal decompression in adult patients with thoracolumbar burst fracture.

Data of key medical disciplines and talented personnel training in Jiangsu Province were analyzed,and a plan for their future development is proposed.

ObjectiveTo analysis the clinical features of thoracic spine and spinal cord injury (SCI) and summarize the inclusive standard of cellular transplant clinical trial for SCI.MethodsThe data of 72 cases with thoracic spine and spinal cord injury from 1990 to 2005 were analyzed retrospectively.ResultsMean follow-up period was 20 months (6～48 months). There was no recovery in 12 spinal cord injury without radiographic abnormality (SCIWORA) patients, but improvement of urine function in 4 cases. 5 cases of 52 fracture-dislocation complete injury were improved to grade B (sense recovery), rate of recovery was 9.6%; recovery rate was 62.5% in incomplete injury. Sense recovery of all cases was better than motor recovery. Partial cases appeared spasm paralysis relief.ConclusionIncidence rate of complete injury is high and recovery is bad in thoracic spine and spinal cord injury. The inclusive standard of cellular transplant clinical trial for SCI is old complete thoracic spinal cord injury without residual compression.

Objective To explore the risk factors affecting prognosis of children with Tourette syndrome(TS).Methods The follow-up visits were conducted on the clinical data of 98 cases with TS(85 male,13 female;aged 4-16 years old)from 1997 to 2005 in Wuhan children's hospital.All cases were consistent with the diagnostic criteria of TS in the 4th edition of Diagnostic and Statistical Manual of Mental Disorders(DSM-Ⅳ).The investigations were performed by the investigators who received special training using the unified questionnaire with the methods of direct inquiry or by telephone.The factors included sex,age,severity of TS,the primary symptoms,family history,coexisting diseases,basic diseases,perinatal abnormity and family-social relations.The prognosis of TS and these factors were analyzed by linear regression and stepwise regression with SPSS 12.0 software.Results About 16 cases lost follow-up and the other 82 cases with follow-up(72 male and 10 female)received retrospective review.They were 14 to 25 years old with complete data,and 50 cases healed,32 cases not healed.Results from non-conditional simple variant Logistic regression showed that such cases were associated with the following factors:age,family history of TS,severity of TS,coexisting diseases,basic diseases and perinatal abnormity(Pa0.05).Out of 6 suspicious factors,there were coexisting diseases(OR=84.088,95%CI 10.850-651.682),severity of TS(OR=13.956,95% CI 2.412-80.762),and family history of TS(OR=27.127,95% CI 1.047-702.831)of risk factors.Conclusion The long-term prognosis of children with TS may be related with coexisting disease,severity of TS and family history respectively.

Objective To deeply understand the risk factors of lymphedema for patients with breast cancer after surgery. Methods The phenomenological method was applied in this study. Semi-structured interview was used to collected data from 9 female breast cancer patients with lymphedema after surgery in our hospital from June to September 2016 for generic analysis. Results The risk factors of lymphedema could be categorized into four themes:(1)choice of treatment is the primary cause:axillary lymph node dissection; radiotherapy; chemotherapy; (2)not paying enough attention to lymphedema:lacking the knowledge of lymphedema; imbalance of physical activities for the affected limb; lacking awareness of exercise and protection of the affected limb. Conclusions Axillary lymph node dissection after radical surgery for patients with breast cancer is the primary cause of lymphedema, and paying not enough attention is an important factor, especially lacking the consciousness of prevention, so the nurses should emphasize education about prevention of lymphedema after surgery for patients, to improve the consciousness of them to reduce the occurrence of lymphedema and its influence on their quality of life.

Objective To compare the effectiveness of comprehensive rehabilitation therapy with that of surgical intervention for patients with recurrent lumbar disc herniation (LDH).Methods A total of 124 LDH patients were recruited antd randomly divided into an experimental group and a control group,each of 62.The experimental group was given comprehensive rehabilitation consisting of medicine,physical therapy,and spinal stabilization exercises,while the control group received lumbar spine surgery.The patients' back and leg pain scores and their Oswestry Disability Index (ODI) scores were compared at admission and discharge,as well as 3 and 12 months after discharge.Anxiety and depression were also assessed at admission and 3 months after discharge.Results At discharge and 3 and 12 months later the average back and leg pain scores and ODI ratings were significantly lower than that at admisshin for both groups.There were no significant inter-group differences.In terms of anxiety and depression,however,these had decreased signifieantly in both groups,but the experimental group's average rating was significantly better at diseharge.Conclusions Comprehensive rehabilitation is superior to surgical intervention in relieving the depression of patients with recurrent LDH.Comprehensive rehabilitation should be considered as the first ehoiee for patients with rccurrent LDH,and only supplemented by surgical intervention if it is not effective.

The text analyzes the reasons of medical devices adverse events occurrence from manufacturers, medical institutions and patients. To guard against the events, the medical institutions should put emphasis on check of purchasing, informed consent, technical permission, SOP performing, the safe of medical and enhance monitoring etc.

OBJECTIVETo explore the character of inorganic elements in Polygonum multiflorum.

METHODThe contents of elements such as Al, B, Ba, Ca, Cu, Mn, Mg, Fe, Na, Ni, P, Se, Sr, Ti and Zn in nine P. multiflorum samples were determined by means of ICP-AEC. The results were used for the development of element distrubution diagram. The principal component analysis and one-way ANOVA of SPSS were applied for the study of characteristic elements in P. multiflorum.

RESULTThe contents of Al, Ca, K, Mg, Sr,Ti in wild P. multiflorum were remarkable higher than those in cultured P. multiflorum, and there was no significant difference between cultured and wild in the other elements. Five principal components which accounted for over 90% of the total variance were extracted from the original data. The analysis results show that Al, B, Ba, Fe, Na, Ni, Ti, Ca and Sr may be the characteristic elements in P. multiflorum. The element distrubution diagram of the sample from Tianyang was remarkable different comparing with the others.

CONCLUSIONThe principal component analysis could be used in data processing in inorganic elements.
