OBJECTIVETo analyze the reason and strategy for failure of posterior pedicle screw short-segment internal fixation on thoracolumbar fractures.

METHODSFrom March 2008 to December 2010,the clinical data of 18 patients with thoracolumbar fracture failed in posterior pedicle screw short-segment internal fixation were retrospectively analyzed. There were 11 males and 7 females with an average age of 37.2 years (ranged, 19 to 63). The time from the first operation to complication occurrence was from 6 to 44 months with an average of 14.3 months. Of them,fusion failure was in 7 cases (combined with screw breakage in 4 cases), the progressive neuro-dysfunction was in 5 cases,the progressive lumbodorsal pain was in 6 cases. All 18 patients with kyphosis were treated with anterior internal fixation remaining posterior fixation (9 cases) and anterior internal fixation after posterior fixation removal (9 cases).

RESULTSAll the patients were followed up from 18 to 50 months with an average of 30.5 months. No intetnal fixation loosening and breakage were found, moreover, X-ray and lamellar CT showed bone healing well. Preoperative, postoperative at 3 months and at final follow-up, ODI score was respectively 31.6+/-5.1, 8.6+/-5.7, 8.3+/-3.2; VAS score was respectively 7.2+/-2.3, 2.3+/-0.7, 2.1+/-1.1; kyphosis angle was respectively (-21.2/-+7.8 degreeso, (-5.3+/-6.8 degrees ), (-5.8+/-7.8 )degrees. Compared with preoperative data ,above-listed items had obviously ameliorated(P<0.05).

CONCLUSIONTreatment of thoracolumbar fracture with posterior pedicle screw short-segment internal fixation may result in the complications such as bone nonunion ,internal fixation breakage and progressive kyphosis. Anterior reconstruction may be a good strategy for the failure of posterior operation.

Objective To evaluate the clinical efficacy and safety of integrated traditional Chinese and Western medicine in treating active rheumatoid arthritis (aRA).Methods A prospective randomized controlled study was carried out. Totally 148 aRA patients were divided into the control group and the treatment group, 74 cases in each group. Control group was treated with MTX (methotrexate) and LEF (leflunomide), while the treatment group took traditional Chinese medicine based on syndrome differentiation, on the basis of treatment with MTX and LEF. The therapeutic course for all was 3 months. Efficacy indexes, like clinical symptoms and signs, ESR, TCM syndrome integrals, DAS 28 score, and safety indexes were observed.Results This study finally completed 136 cases, including 69 cases in the treatment group and 67 cases in the control group. In the two groups, significant improvement of clinical signs and symptoms, ESR, DAS28, and TCM syndrome integrals after treatment were shown, with statistical significance (P<0.01). Better effects were obtained in the treatment group in lessening tender joint numbers and swollen joint numbers, DAS28, and TCM syndrome integrals (P<0.01). The total effective rate of the TCM syndrome efficacy was 86.96% (60/69) in the treatment group, and 76.12% (51/67) in the control group, without statistical significance (P>0.05). The significant efficiency of the treatment group was 11.59% (8/69), and the control group was 5.97% (4/67), with statistical significance (P<0.05). Adverse reactions occurred fewer in the treatment group than in the control group (P<0.01).Conclusion Compared with single traditional Chinese medicine, integrated traditional Chinese and Western medicine for treating aRA can better improve DAS28 and TCM syndrome integrals, and reduce the incidence of adverse reactions.

ObjectiveTo investigate the relationship between the serum concentration of IL-6,S100β,NT-3 and the cognitive functions in first-episode schizophrenia characterized by positive or negative symptoms.Methods44 first-episode schizophrenic patients characterized by positive symptoms (positive group),36 first-episode schizophrenic patients characterized by negative symptoms (negative group) and 50 healthy controls (controls) were collected.The serum levels of IL-6,S100β and NT-3 were measured by enzyme-linked immunosorbent assay (ELISA).The systematic evaluation tool-MCCB was applied to assess cognitive function in patients and controls.ResultsNT-3 serum levels in positive or negative groups were lower than those in controls and the differences were significant((118.39±37.50) ng/L,(112.55±32.29) ng/L vs (141.18±29.67) ng/L) (P<0.01).IL-6 and S100β serum levels in positive or negative groups were higher than those in controls and the differences were statistically significant((5.74±1.00)ng/L,(5.07±1.17)ng/L vs (4.23±0.91)ng/L),((132.98±46.71)ng/L,(124.99±43.14)ng/L vs (103.63±31.57)ng/L)(P<0.01).IL-6 serum levels in the positive group ((5.07±1.17)ng/L) were lower than those in the negative group ((5.74±0.99)ng/L) and the difference was statistically significant (P<0.05).In MCCB test,the TMT scores in patients characterize by positive symptoms or patients characterize by negative symptoms were higher than those in healthy control group (P<0.01).BACS SC,HVLT-R WMS-Ⅲ,SS,NAB,BVMT-R,CF in patients characterize by positive symptoms or by negative symptoms were lower than those in healthy control group(P<0.01).There were no statistical difference in the MCCB scores between the patients with positive symptoms and negative symptoms.In positive group,there was a positive correlation between the IL-6 serum concentration and the general symptom scores in PANSS (P<0.05).In positive group,NT-3 serum concentration was positively correlated with the general symptom scores or total scores of PANSS (P<0.05).BVMT-R scores in MCCB were also positively correlated with IL-6 or NT-3 serum concentration in positive group (P<0.05).ConclusionThe impairment of part of cognitive functions for schizophrenic patients may be related to the serum protein factors.There may be different in pathophysiology between the first-episode schizophrenic patients characterized by positive symptoms and those characterized by negative symptoms.
