OBJECTIVETo investigate the clinical manifestation and surgical outcome of spinal osteoblastoma.

METHODSFrom June 2006 to July 2010, 11 patients with spinal osteoblastoma treated surgically were analyzed retrospectively. There were 7 males and 4 females with an average age of 23.5 years (range, 16 - 34 years). The tumors were located at C(5) in 3, C(6) in 4, C(7) in 2, C(6) ~ T(1) in 1 and T(11) in 1. Based on WBB classification, 9 were 1 - 3 or 10 - 12 and 2 were 4 - 9 and 1 - 3. All the operations had been performed with en-bloc resection. The posterior approach was used for 9 patients, and combined posterior and anterior approach was used for 2 patients. Reconstruction using instrumentation and fusion was performed using spinal instrumentation in 8 patients. To evaluate the change of pain before and after the operation by visual analogue scales (VAS), and to assess functional status of the spine by McCormick scale. Imaging test was used to review the stability and recurrence rate of spine cord, and the confluence of graft bones.

RESULTSAll cases were followed up for 12 - 64 months (average, 28.4 months). The average surgical time was 130.5 minutes (range, 90 - 210 minutes), with the average intraoperative blood loss of 560 ml (range, 300 - 1000 ml). During the follow-up period, the VAS grade reduced from 6.3 ± 1.1 to 2.5 ± 1.0 (t = 8.48, P < 0.05). There were 8 patients had neurological function improved and 3 remained no change which was evaluated by McCormick scale for spinal function status at final follow-up.

CONCLUSIONSSpinal osteoblastoma has its own specific radiographic feature. There are some recurrence in simple curettage of tumor lesion. The thoroughly en-bloc resection of tumor or spondylectomy, bone fusion and strong in ter fixation are the key points for successful surgical treatment.

OBJECTIVETo investigate the expression of TSC1, TSC2, p-mTOR, p-4E-BP1, p-p70S6K and p-S6 in refractory epilepsy associated malformation of cortical development (MCD) tissues.

METHODSA total of 43 cases of refractory epilepsy were involved in the study, and all the patients were treated in Xuanwu Hospital during 2005 - 2008, including focal cortical dysplasia type IIa (11 cases) and type IIb (11 cases), tuberous sclerosis complex (10 cases) and ganalioglioma (11 cases), and other 12 cases were used as control. These cases were divided into 7 study groups and immunohistochemical EnVision method was used. To detect the location and intensity of TSC1, TSC2, p-mTOR, p-4E-BP1, p-p70S6K and p-S6 expression in every group. Then the Image-Pro Plus 6.0 image processing and analysis software were used to measure the number, area, integrating absorbance (IA) of positive cells in every samples. The statistical software SPSS 16.0 was used to analyze the data.

RESULTSThe immunolocalization of TSC1 and TSC2 was similar. It could be observed the expression of various levels in the cytoplasm of dysmorphic neurons, balloon cells, giant cells, ganglioglioma cells and normal neurons. TSC1 staining in normal neurons was more notably than others but TSC2 staining in giant cells was weaker than other samples. p-mTOR mainly presented in giant cells, which could also be observed in astrocyte. P-4E-BP1 presented in the cytoplasm and nuclear membrane of balloon cells, giant cells and ganglioglioma cells, the staining of giant cells was stronger than balloon cells, but their staining were weaker than ganglioglioma cells. P-p70S6K mainly expressed in giant cells and less commonly presented in balloon cells. P-S6 typically presented in all abnormal glioneuronal cells and it nearly did not present in the normal neurons of N-CTX group.

CONCLUSIONSPI3K pathway, at least in part, involves in the occurrence of MCD, and may play an important role in the pathogenesis.

OBJECTIVETo study the effects of overweight and obesity on physical function (including systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse, weight vital capacity index) in children and adolescents.

METHODSThe data of 2010 Chinese National Survey on Students Constitution and Health was analyzed. The samples of overweight and normal-weight group were randomly selected from the data by matching gender, urban or rural for getting the same number sample size as obese group (10 601 each group). The students aged 7 - 18 years were classified into 3 groups by BMI percentiles (P₅, P₁₅, P₂₅, P₅₀, P₇₅, P₈₅ and P₉₅), to analyze the change of physical function along with BMI percentile.

RESULTSCompared to the normal-weigh group, SBP of the obese boys of all age groups increased by 8.0 - 12.0 mm Hg, DBP increased by 4.7 - 5.9 mm Hg, while SBP of the obese girls increased by 7.5 - 11.6 mm Hg, DBP increased by 4.7 - 6.1 mm Hg, with statistical significance (P < 0.05). In 13 - 15-year group, pulse of obese boys was 0.8 times/min higher than that of normal-weight. In 16 - 18-year group, pulse of obese boys was 1.1 times/min higher than that of overweight or normal-weight, while pulse of obese girls were 1.5 and 1.7 times/min higher than that of overweight and normal-weight, respectively (P < 0.05). Pulses in boys aged 7 - 9 years when BMI were P₅, P₅₀, P(95) were 87.63, 87.00, 87.83 times/min, and pulses in boys aged 10 - 12 were 85.66, 85.30, 85.43 times/min, respectively. Pulses in boys aged 13 - 15 years when BMI were P₅, P₅₀, P₉₅ were 82.60, 81.39, 82.34 times/min, and pulses in boys aged 16 - 18 years were 80.15, 79.00, 79.98 times/min. In both boys and girls of all age groups, weight vital capacity index had the trend of obese < overweight < normal-weight (P < 0.05). Compared to the normal-weight group, weight vital capacity index of overweight boys decreased by 6.4 - 8.4 ml/kg, that of obese boys decreased by 11.9 - 14.8 ml/kg, while that of overweight girls decreased by 5.3 - 7.7 ml/kg, that of obese girls decreased 11.0 - 11.5 ml/kg.

CONCLUSIONCompared to the normal-weight, overweight and obese children and adolescents had elevated blood pressure, increased pulse, decreased weight vital capacity index.

OBJECTIVETo explore the traumatic mechanism and the effectiveness of conservative and operative therapy for intra-articular fracture of calcaneus.

METHODSForty-eight patients (52 feet) with intra-articular fractures were divided into two groups named as conservative group and operative group. There were 30 patients in the conservative group, including 26 males and 4 females, ranging in age from 2 to 73 years, with an average of (49.2 +/- 8.5) years. The patients in conservative group were treated with manual reduction, external fixation and functional exercise at early time. Among 18 patients in the operative group, 14 patients were male and 4 patients were female, ranging in age from 26 to 66 years,with an average of (50.1 +/- 19.3) years. The patients in the operative group were treated with open reduction and internal fixation. The height and width of calcaneus, Böhler and Gissane angles were measured before and after treatment. The assessment in the function of ankle joints was scored according to AOFAS scoring system.

RESULTSAll the patients were followed up, and the duration ranged from 8 to 18 months,with a mean of 12 months. The time of weight-bearing ranged from 3 to 6 months, averaged 4 months. The fractures were fused completely on average of 12 months. The height and width of calcaneus, Böhler and Gissane angles had no statistically significance between two groups. According to AOFAS criteria,in the conservative group, 18 patients reached an excellent result, 6 good, 5 poor and 1 bad; in operative group, 4 patients reached an excellent result, 7 good, 6 poor and 1 bad. The therapeutic effect of conservative group was better than that of operative group.

CONCLUSIONOperative therapy in intra-articular fracture of calcaneus with steel plate can directly perceive the restoration (or roughly restoration sometimes) of the anatomical shapes of calcaneus, while conservative therapy has advantages such as restoration of the anatomical shapes of calcaneus, early functional practice, early healing, and avoiding operational complications as well.
