BACKGROUND:Patients with spinal metastases may appear different degrees of pain and abnormal spinal stability, and can be treated with percutaneous baloon kyphoplasty combined with bone cement implantation. OBJECTIVE:To explore the effect of percutaneous baloon kyphoplasty with bone cement implantation on spinal stability and pain in patients with spinal metastases. METHODS:Twenty-three patients with metastatic spinal tumor were treated with percutaneous baloon dilatation kyphoplasty with polymethyl methacrylate bone cement. There were 10 females and 13 males, and their age ranged from 23 to 71 years. The visual analogue scale score, anterior and posterior edge height of vertebral body, quality of life, and motor function score of patients were observed before and after treatment. RESULTS AND CONCLUSION: Compared with before treatment, the visual analogue scale score and motor function score were significantly decreased, while anterior and posterior edge height of vertebral body were significantly increased in 23 patients at 24 hours after treatment (P < 0.05). After 12 months of folow-up, no case appeared to have spinal nerve root damage, serious adverse reactions and bone cement embolism. The patient'squality of life was significantly improved, compared with before treatment (P < 0.05). Experimental findings indicate that percutaneous baloon dilatation kyphoplasty with polymethyl methacrylate bone cement can significantly improve the spinal stability, relieve the degree of pain, and exert exact effects in treatment of spinal metastases.

OBJECTIVETo observe the clinical effect of Sizhi-Xifang in the improvement of postoperative ankle function.

METHODSFrom Jan. 2006 to Mar. 2008,49 patients were divided randomly into treatment group and control group. The treatment group included 16 males and 8 females with an average age of (41.3 +/- 13.2) years, involving 13 cases of tye A, 9 of type B and 2 of type C based on AO classification. The control group included 15 males and 10 females with an average age of (38.2 +/- 10.9) years, involving 12 cases of type A, 10 of type B, 3 of type C. Minimal invasive percutaneous plate were used in each group. In treatment group 24 cases were treated with Sizhi-Xifang after the incisions were healed.

RESULTSThere were no incision infections, flaps necrosis, bone and plate exposure after treatment in two groups. All patients were followed-up for 4 to 16 months with an average of 8.6 months. According to Johner-Wruhs evaluation standard, there were 7 cases in excellent, 12 good, 5 in fair in treatment group and in control group there were 5 cases in excellent, 7 in good, 10 in fair and 3 in poor. The comparison of effect between two groups had significant difference (P < 0.05).

CONCLUSIONSizhi-Xifang is helpful to improve the ankle postoperative function.

Different from the traditional teaching method, PBL (Problem-Based Learning) teaching mode is emphasized to foster the students' skills in spontaneous study and problem solving and the analyzing and comprehensive thinking ability. The authors believe that in the application of the PBL teaching method, the teachers' functions should be stressed on how to select the initial moment, provide the topics, excite the interesting points, search information,make comments and evaluate the students' ability, i.e. to offer fish and teach how to catch fish as well.

There is rich scientific information in the traditional Chinese medicine ( TCM ) patents . However , few of them have been efficiently utilized by the academic researchers for a long time . In this paper , TCM patent literatures from 1992 to 2011 were collected by retrieving with SooPat patent searching engine . A total of 638 TCM entries have been indexed, which are consistent with the index in the Modern Chinese Materia Medica. The patents with special academic values were manually screened , and were finally stored in an Access database . A survey on the filed patents was outlined . The work provided a new information resource for the TCM researchers. And it was important to promote the effective use of TCM patents.

Objective To assess the clinical significance of three-dimensional speckle tracking imaging (3D-STI) in the evaluation of left ventricular myocardial function in breast cancer survivors with postoperative anthracycline-based chemotherapy.Methods A total of 51 breast cancer survivors with postoperative anthracycline-based chemotherapy were recruited and 31 female healthy volunteers as the controls.Conventional echocardiography and 3D-STI derived parameters [including global longitudinal strain (GLS) and global area strain (GAS)] were measured before and at 3 and 6 anthracycline-based chemotherapeutic cycles.The receiver operating characteristics (ROC) curve was constructed to determine optimal sensitivity and specificity of 3ID-STI derived parameters for the prediction of future cardiotoxicity.Results In comparison with the controls and baseline cases,GLS and GAS deteriorated significantly (P ＜ 0.05 for both).No statistical difference in GCS and conventional parameters showed before and after the initiation of chemotherapy (P ＜0.05,respectively).The ROC curves showed that GAS as the best 3D-STI predictor of patients who develop cardiotoxicity during the follow-up.The area under ROC(AUC) of GAS was 0.894,and its optimal cut-off value was-28.4％,with a specificity of 88.0％ and a sensitivity of 82.9％.AUC of GLS was 0.802,and its optimal cut-off value was-14.3％,with a specificity of 62.0％ and a sensitivity of 85.4％.Conclusions Early decreases in GAS and GLS based on 3D-STI may allow the prediction of subsequent cardiotoxic development accurately in breast cancer survivors with postoperative anthracycline-based chemotherapy.

To observe the influence of Mycobacterium tuberculosis 19-kDa lipoprotein (Mtb P19) on function and phenotype of macrophage,the Mtb P19 was prepared from cultured Mtb H37Ra and the phorbol myristate acetate-differentiated THP-1 cells were incubated with P19 at the concentration of 10 μg/mL with 5% CO_2 at 37℃ for up to 48 hours.Supernatants were collected for TNF-α and IL-6 detection by ELISA,then the phenotype fluorescent antibodies were stained to analyze HLA-DR expression changes between control group and experimental group.Flow cytometry and microscopy was used to assay the phagocytosis in macrophages stimulated by Mtb P19.IL-6 and TNF-α in collected supernatants were detected.Results indicated that both were found significant increases and their phagocytosis were enhanced.Comparing to the control group,the mean fluorescence intensity showed a significant increase 24hs after stimulation.It presents that Mtb P19 could be able to induce macrophages activation,and it would be significantly important for protection during infection period.

Contents in orthopaedic are independent relatively and finding out the internal relations during them is helpful to improving the effect of orthopaedic teaching.Transfer theory is important tools for clinical teaching practice,and finding out the common characteristics between the orthopaedic chapters is primary for the theory.This research focuses on the following fields:fractures,nerve injury,infection,tumor and deformity.After the common characteristics between these chapters were analyzed and discussed,we concluded that the transfer theory is helpful in orthopaedic teaching practice,especially for students' comprehension and memory,but still we should avoid some negative effects in teaching process.

ObjectiveTo investigate the cause,diagnosis and treatment measures of neonatal pneumothorax.MethodsThe clinical data of 98 cases with neonatal pneumothorax in our hospital from Mar 2005 to Mar 2010 were reviewed retrospectively.ResultsThere were 27 premature neonates and 71 full-term neonates in the 98 cases.Ten cases were spontaneous pneumothorax and 88 cases were non spontaneous pneumothorax.After the treatnent of primary disease,pleural aspiration,chest drainage and mechanical ventilation,88 cases were cured,8 cases were improved and 2 cases died.ConclusionNeonatal pneumothorax is related with cesarean section,improper use of endotracheal intubation,meconium aspiration,premature hyaline membrane disease using pulmonary surfactant and ventilator therapy.Most pneumothorax is due to lung disease.The prevention of preterm birth and asphyxia can reduce the incidence of neonatal pneumothorax.

Objective To study the risk factor of postoperative acute lung injury(ALI)after liver transplantation.Methods The clinical data of I00 patients with end-stage liver diseases who re- ceived liver transplantations were retrospectively reviewed.The risk factors of postoperative ALI after liver transplantation were analyzed by using single variance analysis and multiple variance regression analysis.Results Thirteen patients(13 %,13/11t0)altogether were diagnosed as ALI after liver transplantation.Binary logistic analysis revealed that massive transfusion during operation(more than 5000 ml)and severity of reperfusion injury(ALT above 600 U/L)were two independent risk factors of postoperative ALI following liver transplantation.Massive transfusion significantly increased the risk of ALI by 12.7 times,whereas the severe reperfusion significantly increased the risk of ALI by 7.0 times.Conclusions ALl is a serious multifactoral complication after liver transplantation with high mortality and fatality.Massive transfusion and the severe reperfusion injury are two independent risk factors with high morbidity and mortality.
