Objective To evaluate the efficacy of internal fixation with or without fusion in the treatment of thoracolumbar burst fractures.Methods Clinical controlled trails related to the application of pedicle screw instrumentation with or without fusion for thoracolumbar fractures before March,2012were obtained by searching PubMed,Science Direct,Medline and CNKI.Quality evaluation was made on the included literature,from which data were extracted to integrate various rescarch results by using RevMan 5.1.The quantitative data were analyzed based on the effect scale of mean difference (MD) and bilateral 95％ confidence interval (CI).The numeration data were analyzed in the use of effect scale of odds ratio (OR) and bilateral 95％ CI.The merging of some data was manually completed.Results After retrieving,eight English and one Chinese papers of the clinical controlled trials,and two related Meta analysis were obtained.With exclusion of one repetitive research,eight papers were involved in the review.Meta analysis demonstrated that fusion and non-fusion fixation had no significant differences in aspects of correction of kyphotic angle,correction and correction loss of vertebral body height,neurological function improvement,complication rate,and length of hospital stay.While compared with the fusion fixation,non-fusion fixation showed a more serious correction loss of kyphotic angle,a fewer blood loss and a shorter operation time.Conclusions Non-fusion fixation shows the similar efficacy with fusion fixation in the treatment of some thoracolumbar burst fractures pertaining to releasing compression,restoring spinal stability and preventing complications,but it can also significantly decrease operation time and blood loss.Furthermore,non-fusion fixation may markedly improve patients' quality of life since it restores motion of the instrumented segment after removal of implant and decreases the risk of adjacent segmental degeneration.

Objective To evaluate the long-term clinical efficacy of iliac bone block allograft in anterior reconstruction of thoracolumbar fractures.Methods A follow-up study was carried out on 93 patients with thoracolumbar fractures treated by anterior decompression and interbody fusion with iliac bone block allograft from February 2004 to March 2007.The radiographic and clinical outcomes were retrospectively assessed.Results Sixty-six patients were followed up for 60-97 months (mean,78 months).The effective interbody fusion rate was 100％,with the fusion time of 6-12 months (mean,10 months).The Cobb' s angle corrected from pre-operative (21.6 ± 8.3)° to post-operative (5.8 ±5.2)°,but when the infusion became effective,the angle showed average loss of 2.4°.All the 66 patients were associated with various degrees of neurological deficiency,but the patients with incomplete nerve dysfunction obtained different degree of recovery.Conclusions Iliac bone block allograft is effective in reconstruction of spinal anterior-middle column stability with the aid of internal fixation instruments.Thereby,it may be a potential alternative to autograft in the treatment of thoracolumbar fractures and can attain early and late stage persistent spinal stability.

Objective To observe the osteogenic effect of tissue-engineered bone constructed by poly-L-lysine-demineralized bone matrix (PLL-DBM) enriched bone marrow stem cells in the space of goat transverse process bone fusion model and explore a new tissue-engineered bone construction method. Methods PLL was used to decorate goat DBM to prepare a matrix material (PLL-DBM). The osteo-genic effect of tissue-engineered bone constructed by PLL-DBM enriched bone marrow cells ( Group Ⅰ A) was detected in goat lumbar intertransverse graft bone model; autogenous iliac bone (Group Ⅰ B), DBM enriched bone marrow (Group Ⅱ C) and DBM (Group Ⅱ D) were used as controls. The osteogenesis of the bones in the fused segments of four groups were compared and evaluated by X-ray, three-dimensional CT, CT value testing and biomechanical testing. Results The results of X-ray showed that the fusion ranges in groups ⅠA and ⅠB were basically the same, which were significantly wider than that in Group Ⅱ, with no fusion detected in Group Ⅱ D. The CT value was (696.76±10275) HU in Group Ⅰ A and (766.03±69.24) HU in Group B, which were significantly higher than that in Group Ⅱ C (P <0.05), but there was no statistical difference in CT value between Groups Ⅰ A and Ⅰ B (P > 0.05). The CT val-ue in Group Ⅱ C was significantly higher than in Group ⅡD (P <0.01). There was no statistical differ-ence between Groups Ⅰ A and Ⅰ B in the maximum load and bending strength (P > 0.05). The maxi-mum load and bending strength in Groups Ⅰ A and Ⅰ B were significantly higher than that in Group Ⅱ C (P < 0.05), and the two indices in Group Ⅱ C were significantly higher than that in Group Ⅱ D (P <0.01). Conclusion Tissue-engineered bone constructed by PLL-DBM enriched bone marrow cells is an ideal tissue engineered bone and its osteogenic potential is similar to that of autologous bone.

Objective To explore the method and efficiency of percutaneous transluminal septal tunnet myocardial ablation(PTSTMA) in treatment of 26 cases hypertrophic obstructive cardiomyopathy (HOCM) who were not suitable for conventional technology.Methods Firstly,we used a monorail Balloon which was slightly bigger than the interventricular septal branch of coronary artery and dilated it until posterior septal.After that,an OTW Balloon with larger size than the monorail was used to dilate again until made aventricular septum tunnel.Then,some alcohol was injected and PTSTMA was performed.Finally,we did the other and/or another interventricular septal branch by above method until the left ventricular outflow tract pressure gradient (LVOTPG) reduced ≥50％.The clinical indexes of the 26 cases HOCM immediately pest-operation of PTSTMA were observed and the follow up data during short term and metaphase were analyzed.Results The LVOTPG reduced ≥50％ in the26 cases HOCM,immediately after PTSTMA,the LVOTPG reduced from (75.6 ±22.4)mm Hg to (21.4 ± 5.8) mm Hg (t =11.94,P ＜ 0.01).At three months after ablation,the thickness of septal myocardium reduced from (22.8 ± 5.8) ram before ablation to (16.8 ± 4.2) mm(t =4.27,P ＜ 0.01),left atrium dimension reduced from(48.0 ±7.0) mm to (42.0 ±8.6) mm (t =2.76,P ＜0.01).Followed up 6.0to 60.0 months,the patients suffering from chest pain reduced from 14 cases before to 4 cases after the procedure(53.8％ (14/26) vs 15.4％ (4/26),x2 =8.49,P ＜ 0.01),the patients with expiratory dyspnea reduced from 26 cases to 5 cases(100％ (26/26) vs 19.2％ (5/26),x2 =35.22,P ＜ 0.01),NYHA functional class improved from (2.4 ± 0.6) to (1.4 ± 0.7) (t =5.53,P ＜ 0.01).Conclusion The PTSTMA was a supplemental method of PTSMA on treating HOCM,which was safe and useful during the short term and metaphase.

Objective To investigate the effect of Ginsensode Rgl on the expression of Neurogranin (Ng) and behavioral alteration in cortex and hippocampus of rats with chronic stress model.Methods A total of 36 adult male SD rats were randomly divided into control group (CON),model group (CUS) and treatment group (CUS-G).The chronic stress model was established by chronic unpredictable stress.The Morris water maze was used to study the learning and memory ability.The content of Ng in cortex,hippocampus was detected by RT-PCR and Western blot.Results The water maze test showed that after chronic stress,animal learning and memory ability decreased significantly,while the treatment group rats escape latency was significantly reduced (P＜0.05);after 6 weeks of stress,the cortex and hippocampus Ng mRNA levelschronic stress rats were markedly lower than that of model rats respectively (P＜0.05,P＜0.01,P＜0.05).The cerebral cortex and hippocampus Ng mRNA levels in treatment group were significantly increased compared with that of model group respectively (P＜0.01,P＜ 0.05,P＜0.05);The cerebral cortex and hippocampus Ng levels of chronic stress rat were significantly decreased when compared with that of the model rats respectively (P＜0.05,P＜0.01,P＜0.05),The cerebral cortex and hippocampus Ng content were significantly increased in treatment group compared with the model group respectively (P＜0.01,P＜0.05).Conclusions Chronic stress can change the behaviors of nice in recognization and memory The contents of Ng and the supplement of Ginsensode Rg1 have positive adjustment.

Objective To investigate the mechanism and prevention of syncope on patients with hypertrophic cardiomyopathy (HCM). Methods Seventy-six cases of HOCM (obstruction group) were successfully operated by PTSMA and oral ACEI/ARB. After six months , they were treated with β-receptor blocker. Another 29 patients (control group) with LVOTPG < 50 mmHg or < 70 mmHg after pharmacologic stress test (PST), have being treated with β-receptor blocker. The results was observed as follow: (1) the difference of between syncope incidence and positive incidence induced by PST in control group; (2) the difference of syncope incidence at half year, a year and admission in control group; (3) the difference of syncope incidence in obstruction group before and after operation; (4) the difference of syncope incidence after six months between two groups at same period; (5) the difference of syncope incidence one year between two groups. Results In control group, the syncope positive incidence induced PST was 55.5%. Treating with medications for half a year , syncope incidence significantly dropped than that on admission (P < 0.05); Obstruction group syncope incidence in the history obviously lower than the control group syncope positive induced PST (P < 0.05), and half a year after takingβ-receptor blocker syncope incidence was significantly dropped than before (P < 0.01). Conclusions The mechanism of syncope with HOCM is not only obstruction but also neuronal reflex. PST is an very useful inspection item for screening the ablation indication, analysis syncope mechanism, and guiding clinical medication.β-receptor blocker is an effective drug on treating and preventing syncope with HCM.

Objective To study the efficacy and safety of four surgical techniques of tuberculosis of lumbosacral junction retrospectively. Methods Between Jul 2001 and Jan 2013, 79 patients with lumbosacral spinal tuberculosis underwent surgery. Antituberculous chemotherapy and nutrition support prior to surgery were used for at least two weeks. 45 patients underwent single stage radical debridement, fusion and anterior instrumentation (A group). 18 patients underwent combined anterior and posterior spinal surgery (AP group), 10 patients underwent transpedicular drainage, posterior instrumentation, and fusion (P group), and 6 patients underwent anterior radical debridement (D group). All the patients were treated by antituberculous chemotherapy for 18 months and followed regularly. The operation duration, blood loss, clinical status, ESR, VAS, ODI, roentgenogram and 3D?CT were concerned to estimate the progress of tuberculosis. Radiographs were analyzed before surgery, immediately after surgery, and at the final follow?up examination to assess the result of anterior fusion and maintenance of correction. Results There was no inju?ry of blood vessel, ureter or cauda equina during surgery. The mean follow?up period was 23 months (range 18-42 months). No obvious loss of deformity correction was observed. There was no recurrence, no tuberculous peritonitis, and no incidence of im?potence or retrograde ejaculation in any of these patients. The average operating duration(min) were 144.31 ± 23.18, 444.72 ± 141.63, 351.50 ± 85.25, 90.00 ± 29.66, respectively; The average blood loss(ml)were 266.67 ± 104.45, 988.99 ± 488.26, 890.00 ± 306.23, 200.00±104.88, respectively; The average Pre?op VAS were 4.71±1.79, 5.22±1.48, 3.30±1.64, 2.50±1.52, respectively;The average last follow?up VAS were 0.89±0.68, 0.90±0.74, 1.00±0.63, respectively; The average Pre?op ODI(%)were 29.64± 7.85, 32.17±7.59, 28.20±4.26, 20.67±4.63, respectively; The average last follow?up ODI(%)were 5.09±3.59, 4.78±3.78, 4.80± 3.39, 4.00 ± 1.18, respectively; The average Pre?op lumbosacral angle(°)were 20.61 ± 4.92, 23.78 ± 5.84, 25.10 ± 4.28, 21.67 ± 4.27, respectively; The average Post?op lumbosacral angle were 27.17±3.66, 30.56±5.31, 32.10±4.01, 24.83±2.32, respectively;The average last follow?up lumbosacral angle were 23.89 ± 3.12, 27.00 ± 5.46, 29.00 ± 4.85, 23.33 ± 2.50, respectively. Conclu?sion Single stage anterior interbody fusion with anterior instrumentation worked effectively to stabilize lumbosacral junction (less invasive, short surgical duration, no injury of posterior column). Anterior interbody fusion combined with posterior instrumentation was recommended for patients with extensive bone defect and low iliocava junction.

Objective To analyse the phenotypes of the drug?resistant tuberculosis, and investigate the outcomes of the individualize surgery and chemotherapy for these patients. Methods From January 2009 to June 2012, we retrospectively ana?lyzed 49 patients with drug?resistant tuberculosis spondylitis admitted in Southwest Hospital. 33 were initial cases and 16 were re?curring cases. All the 49 patients received individualized open operation or CT?guided percutaneous drainage and local chemother?apy depending on the characteristics of the focus. Individualized chemotherapy regimens were tailored for all patients according to the drug?resistant spectrum and all patients were followed up successfully at least 24 months. All the clinical data were collected and analyzed by statistical methods. Results Among the 49 patients, 14 were monoresistance tuberculosis, 11 were polyresis?tance tuberculosis, and 24 cases were multi?drug resistant tuberculosis. Frequence of the drug?restistance from high to low was Iso?niazid, Rifampicin, Streptomycin, Levofloxacin, Dipasic/Rifapentine, Ethambutol, Protionamide, Capreomycin, Paza?aminosalicy?late, and Amikacin. 43 patients received open operation and 6 patients received CT?guided percutaneous drainage and local che?motherapy. Time of the percutaneous drainage was (48±11) days (39-60 days), and all patients received Individualized chemother?apy with an average of (29.5±2.5) months (24-36 months) postoperatively. At the last follow?up, all patients had remarkable pain remission, 44 patients with paraplegia got slight or remarkable recovery and 17 patients with kyphosis got significant correction. Conclusion The main drug?resistant spectrums are Isoniazid、Rifampicin、Streptomycin、Levofloxacin. The individualized sur?gery combined with individualized chemotherapy made according to the drug?resistance is a feasible treatment for the drug?resis?tant tuberculosis especially the multi?drug resistant tuberculosis.
