OBJECTIVETo analyze the clinical effects of short-segment posterior pedicle screw combined with transpedicle vertebral bone grafting in treating thoracolumbar burst fractures.

METHODSFrom March 2008 to March 2013, 62 patients with thoracolumbar burst fractures were treated with short-segment posterior pedicle screw combined with transpedicle vertebral bone grafting. Including 40 males and 22 females, the age from 17 to 65 years old with an average of 38 years. According to AO classification, 34 cases were type A3.1, 7 cases were type A3.2 and 21 cases were type A3.3. Load-sharing scores were from 4 to 6 points with an average of 5.4 points. According to ASIA grade, 2 cases were grade C, 5 cases were grade D and 55 cases were grade E. Preoperative, postoperative at 3 d and final follow-up, the Cobb angle, the relative height of anterior vertebral body and the encroachment rate of spinal canal were measured by X-ray films and computed tomography (CT) scan, meanwhile, the information of bone healing and spinal nerves recovery were observed.

RESULTSAll patients were followed up from 11 to 14 months with an average of 12.2 months. The duration of removing internal fixation were from 9 to 13 months (averaged, 11.5 months). One suffered from infection and was cured by debridement. Two cases had mild pain of back. At 6 months after operation, according to ASIA grade to evaluate never function, 1 case was grade C, 3 cases were grade D and 58 cases were grade E. X-ray and CT showed the fractures obtained good union at final follow-up. The Cobb angle, the relative height of anterior vertebral body and the encroachment rate of spinal canal had obviously improved at 3 days after operation (P<0.05); but there was no significant differences between postoperative at 3 d and final follow-up (P>0.05).

CONCLUSIONShort-segment posterior pedicle screw combined with transpedicle vertebral bone grafting is an effective method to treat thoracolumbar burst fractures. It can reduce the loss of postoperative correction and prevent the internal fixation failure.

Objective To investigate the recurrence and influence factors of spontaneous pneumothorax in patients after thoracoscope surgery. Methods From March 2009 to March 2011,218 patients with spontaneous pneumothorax after thoracoscope surgery in our hospital were surveyed by the self-made general data questionnaire. The clinical data were analyzed by descriptive statistics and binary classification logistic regression analysis of SPSS 19. 0 to find out the infection influential factors of spontaneous pneumothorax for patients after thoraco-scope surgery in order to provide reference basis for reducing postoperative recurrence. Results The recurrence rate of spontaneous pneumo-thorax was 5. 05%(11/218). Multiple logistic regression analysis showed that recurrent pneumothorax ( OR=2. 432,P=0. 000) and multi-ple pulmonary bulla (OR=1. 918,P=0. 000) were the risk factors of spontaneous pneumothorax for patients after thoracoscope surgery. Conclusion The recurrence rate of spontaneous pneumothorax is high,we should strengthen the management of high-risk population and im-prove the prognosis of patients.

Objective To investigate the effect of miRNA-146a expression on the differentiations and functions of CD4 + T lymphocyte in children with psoriasis vulgaris.Methods Thirty children with psoriasis vulgaris and 30 normal controls were enrolled in this study.Quantitative reverse transcription polymerase chain reaction (RT-PCR)was used to detect the expression of miRNA-146a in CD4 + T lymphocytes of the peripheral blood.The CD4 + T lymphocytes were isolated from mononuclear cells prepared with Ficoll-Hypaque density-gradients centrifugation from human peripheral blood by magnetic cells sorting system.The CD4 + T lymphocytes were divided into 3 groups for the experiment:control group,miRNA-146a group,and miRNA-146a inhibitor group.The number of Th1 cells was measured by flow cytometry analysis (FACS).The protein levels and expressions of IFN-γRα were measured by using Western blot and RT-PCR,respectively.The levels of IFN-γ in culture supernatants of CD4 + T lymphocytes were detected by using enzyme-linked immunosorbent assay(ELISA).Results Compared with the normal control group,there was significant increase in the expression of miRNA-146a and serum level of IFN-γ in the psoriasis vulgaris group[2.43±0.94vs1.05 ±0.23,(27.69 ±7.64) ng/Lvs (9.75 ±2.81) ng/L] (t=6.651,4.237,allP＜0.01).There was a positive correlation between miRNA-146a and serum IFN-γ (r =0.837,P ＜ 0.01).However,in vitro,the number of Th1,and supernatant IFN-γ increased,and the expression of IFN-γRα protein decreased in miRNA-146a group compared with that of the control group(all P ＜ 0.01).And the miRNA-146a inhibitor could attenuate the effect of miRNA-146a effectively.Conclusions The miRNA-146a can promote differentiation and improve the function of Th1,It may play an important role in the pathogenesis of psoriasis vulgaris in children.

Objective To evaluate the feasibility and efficacy of minimally invasive percutaneous nephrolithotomy(MPCNL)in the lateral position.Methods A total of 48 patients with staghorn(12 cases,2.2 to 5.8 cm in diameter)or multiple renal calculi(31)or upper ureteral stones(5)were treated with MPCNL in our hospital between July 2004 to October 2007.The patients were placed in a lateral position with the head 10? lower and the feet 20? lower.The puncture was made under the guidance of X-ray or ultrasonography,and then Holmium laser or EMS lithotripter was used for stone fragmentation.The stone debris was removed by irrigation.Results The procedure was completed in all of the 48 patients except one,who was converted to a supine position because of the difficulty in puncture.Among the 47 cases,41 were cured with the first operation,the other 6 received catheterization in the first procedure,and then underwent calculi removal in a second-stage operation.None of the patients were converted to open surgery.The mean operation time in this series was(137.5?39.6)min.The one-stage cure rate in our patients was 82.9%(34/41).None of the cases had massive blood loss,or injuries to the pleura and other organs.Follow-up was available in 21 cases for 1 to 3 months.During the period,among the 17 patients who had hydronephrosis,11 were cured and 6 were improved;and among the 4 who had residual stones,1 received ESWL in 1 months after the first operation and was cured afterwards;the other 3 were treated by traditional Chinese medicine,2 of them were cured.Conclusions The MPCNL performed on the patients in the lateral position is an effective alternative for renal calculi,and favorable to intra-operative anesthesia monitor.

Objective To observe the possible mechanism and inhibitory effects of curcumin on pulmonary fibrosis induced bleomycin in rats at the fibrosing stage. Methods 80 male Sprague-Dawley rats were random divided into 4 groups (20 rats in each group). Rats in the fibrosis model group, the prednisone group and the curcumin group were induced by instilled bleomycin through tracheal, rats in the control group with same volume normal saline. Since the 15th day after bleomycin administration, the curcumin group and prednisone group were given curcumin (300 mg/kg) or prednisone (5mg/kg) per day by intragastric administration, respectively. The normal control group and the model group were given 1% sodium carboxymethyl cellulose ( 10ml/kg). Six rats of each group were random sacrificed on the 21st, 28th, 42nd and 56th days after bleomycin administration. The histological changes of the pulmonary were evaluated by H. E and Masson dyeing. The expressions of transforming growth factor-β1 (TGF-β1), platelet-derived growth factor (PDGF) and hydroxyproline in the tissue of pulmonary were assessed by immunohistochemistry and digestion method. Results Pulmonary fibrosis and hydroxyproline level in the curcumin group were obviously reduced as compared with the model group on the 42nd and 56th day[42 d:1. 28 ±0. 61 vs 2. 28 ±0. 39,P <0. 01 ;(1.73 ±0. 22)mg/g vs (2.50 ±0. 37) mg/g, P <0.01;56 d:1.00 ±0.59 vs 1.73 ±0.36, P< 0. 05; ( 1.57 ± 0. 36) mg/g vs (2. 20 ± 0. 42) mg/g, P < 0. 01 ], and it was also lower than that in prednisone group on the 42nd day( P < 0. 05 ). The expression of TGF-β1 and PDGF in the curcumin group were obviously lower than that in the model group on the 28th, 42nd and 56th day[28 d:TGF-β1 :3642. 05 ±839. 31 vs 5067. 35 ±738. 39, P <0. 05 ;PDGF:2957. 55 ±739. 16 vs 4457. 75 ±568. 39, P <0. 05;42 d: TGF-β1: 2689. 73 ± 529.22 vs 4089. 50 ± 619. 37, P < 0. 01; PDGF: 2834. 46 ± 567. 16 vs 3239. 52 ±628. 26, P <0. 01 ;56 d:TGF-β1: 1968.57 ±408. 36 vs 2968.20 ±498.42, P <0. 01 ;PDGF: 1083.36 ±381.35 vs 2019. 40 ±412. 36, P <0. 01 ], which was lower than that in prednisone group on the 42nd and 56th day (42 d,TGF-β1 :3529. 07 ±981.35,PDGF:2618. 34 ±813. 34;56 d,TGF-β1 :2530. 83 ±439. 37,PDGF: 1738. 35 ±536. 62, Pall <0. 05 ) , and it had no obvious difference compared with control group on the 56th day ( P > 0. 05 ). Conclusion Curcumin could alleviate bleomycin-induced pulmonary fibrosis in rats at the fibrosing stage by inhibiting the expressions of TGF-β1 and PDGF.
