Objective To evaluate the ergotropic effect of bone cement on pedicle screw fixation in treatment of osteopo-rotic thoracolumbar fracture.Methods Fifty-three patients with osteoporotic thoracolumbar fracture, admitted from Jun. 2013 to Dec. 2014, were included for treatment by augmentation of pedicle screw fixation with bone cement. All patients underwent pre-operative examination of bone mineral density with T-score ≤-2.5 and augmentation of pedicle screw fixation with injection of 1.5 ml bone cement in adjacent to fractured vertebra. All patients were treated with anti-osteoporosis therapy pre- and post-operation, ob-served and recorded with basic conditions and complications. At pre-operation, one-week post-operation and last follow-up, pain vi-sual analogue scale (VAS) and neurological function score (ASIA) of all patients were recorded, and the compression rats of anterior and posterior edge of fractured vertebra, and compression rats of spinal canal and Cobb angel of all patients were measured.Results All the 53 patients were successfully undergone operation in about 90-140 min with blood loss of about 150-350 ml. No spinal cord or nerve injury, dural tear and obvious leakage of bone cement and screw loosening occurred during operation. All patients were followed up for 12 to 36 months and the neurological function obviously recovered contrasted with pre-operation. X-ray and CT examination at last follow-up showed good fractures healing, good position and non-loosening of internal fixation device and non-leakage of bone cement. At one week post-operation and last follow-up, VAS, compression rats of anterior edge and posterior edge of fractured vertebra, compression rats of spinal canal and Cobb angel were significantly lower than those at pre-operation (P<0.05), but no significant differences existed on these parameters between 1 week post-operation and last follow-up (P>0.05).Conclusions Augmentation of pedicle screw fixation with bone cement can effectively strengthen the initial stability of pedicle screw in osteo-porosis, restore the height of fractured vertebra and reduce the compression of spinal canal, which will help the correction of spinal kyphosis and neurological function recovery. This method can well maintain long-term stability of internal fixation in osteoporosis and height of fractured vertebra, and significantly reduce the risks of long-term screw loosening and vertebral collapse.

?AIM:To analyze the clinical features of Terrien marginal degeneration ( TMD) .?METHODS:Fifty-six patients(90 eyes) admitted in our hospital from January 2013 to January 2015 were selected as observation group.At the same period, 56 healthy (88 eyes) for corneal examination were as control group to analyze the clinical features of TMD. With immunohistochemistry and enzyme linked immunoassay method ( ELISA), the levels of HLA-DR, HLA-DQ and tumor necrosis factor-α( TNF-α) in blood samples of TMD patients were tested.?RESULTS:The transparent degree of the eye, lipid deposition in TMD patients with early, advanced, swelling and hole-wearing period were significantly different (χ2=10.85,χ2=65.32, P<0.05).Astigmatism in TMD patients with early and advanced, swelling and hole -wearing period were significantly different (P<0.05).The levels of HLA-DR, HLA-DQ and TNF-αin blood samples between the two groups were significantly different ( t=45.326, t=23.564, t=19.86, P<0.05).?CONCLUSION: Terrien's marginal degenerative is an inflammatory disease characterized by increased levels of TNF-α, HLA-DQ, and HLA-DR in peripheral blood, decreased corneal transparency, astigmatism and lipid deposition.This research provides experiment evidence for the mechanism of TMD.

OBJECTIVETo investigate the telomerase activity of human adipose derived stem cells (ADSCs) during proliferation and differentiation in vitro.

METHODSADSCs were highly purified and cultured in vitro. The morphology, phenotype and biological properties of the cultured ADSCs were observed by flow cytometer. Then ADSCs were induced to differentiate into adipocytes and osteoblast. The telomerase activity was detected by TRAP.

RESULTSADSCs had the ability of multi-directed differentiation, like adipocytes and osteoblast. It could also express the stem cell-related surface markers. The telomerase activity was negative or lowly expressed in ADSCs in vitro within 12 generations. The telomerase activity was up-regulated when ADSCs was adipogenic differentiated, but deceased 3-6 days later.

CONCLUSIONSThe telomerase activity of ADSCs is not changed during culture in vitro. It is up-regulated when ADSCs are induced to adipogenic differentiation, but decreased later.

OBJECTIVETo investigate the combined treatment with areola approach for capsular contracture after breast augmentation with implants.

METHODSFrom Feb. 2005 to Jun. 2011, 94 cases (168 sides) with Baker III and IV capsular contracture after breast augmentation with implants were treated with areola approach. The implants cavity was recreated, with or without removal of capsule. The implants were reimplanted behind pectoralis major or breast at the second stage in some patients.

RESULTS46 cases were followed up by clinic visit and the others were followed up by telephone for 6-37 months, with an average of 9.9 months. The capsular contracture was relapsed in 2 cases as Baker III and 1 case as Baker IV. All the other breasts got a good appearance with good soft texture and feeling. No hematoma, infection, implants rupture, breast ptosis or implant displacement happened.

CONCLUSIONSCombined treatment with areola approach has a good therapeutic effect for capsular contracture after breast augmentation with implants. The breast appearance is satisfactory with low occurrence of capsular contracture.

OBJECTIVETo introduce the technique of transarterial interventional embolization treating for arteriovenous malformations (AVM) in the face.

METHODSFrom April 1998, 17 patients have been treated with this method. Seldinger's maneuver was used in this series. Of them, 11 cases received only interventional embolization; 6 cases received both interventional embolization and surgical resection.

RESULTSThe interventional embolization was effective in all the 17 cases, which was confirmed by immediate angiography. Their clinical symptoms were gradually relieved. Interventional embolization obviously decreased hemorrhage during surgical resection.

CONCLUSIONSInterventional embolization provides a new way for the treatment of AVM. Preoperative embolization can lower the surgical risk as it obviously decreases hemorrhage during the surgical procedure.

OBJECTIVETo observe the change of ICBP90 expression in patients with chronic benzene poisoning and explore the correlation between the expression of ICBP90 and benzene-induced hematotoxicity.

METHODSThe bone marrow samples were from 13 chronic benzene poisoning cases with hematopoietic suppression, 11 chronic benzene poisoning cases with hematopoietic regeneration and 10 controls. Western-blot was applied to detect the ICBP90 expression in bone marrow mononuclear cells (BMNCs). The correlation between ICBP90 expression and hematopoietic suppression in patients with chronic benzene poisoning was analyzed.

RESULTSThe ICBP90 expression of BMNCs in 13 chronic benzene poisoning cases with hematopoietic suppression was significantly lower than that in controls (P < 0.01). The ICBP90 expression of BMNCs in 11 chronic benzene poisoning cases with hematopoietic regeneration was significantly higher than those in controls and 13 chronic benzene poisoning cases with hematopoietic suppression (P < 0.05 or P < 0.01), respectively. There were good correlations between the expression of ICBP90 and white blood cell and platelet counts in patients with chronic benzene poisoning (r(1) = 0.555,P = 0.006; r(2) = 0.854,P < 0.01).

CONCLUSIONThe ICBP90 expression of BMNCs in the chronic benzene poisoning cases with hematopoietic suppression decreased significantly, and the ICBP90 expression of BMNCs in the chronic benzene poisoning cases with hematopoietic regeneration increased significantly. There was good correlation between hematopoietic suppression and ICBP90 expression in patients with chronic benzene poisoning.

BACKGROUNDIt is uncertain that the effect of multimodality treatment with operation on survival for locally advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the effect of multimodality treatment with or without operation on survival for locally advanced NSCLC.

METHODSFrom May 1992 to May 1999, 114 patients with locally advanced NSCLC were divided into two arms. Arm A (n=56): 39 cases were at stage IIIA, and 17 at stage IIIB; Median KPS was 80 (range from 70 to 90 ); Multimodality treatment program included operation, chemotherapy, radiotherapy and traditional Chinese herb medicine. Of them, lobectomy plus mediastinal systematic lymph node dissection or lymph node sampling accounted for 49 cases, sleeve lobectomy plus mediastinal lymph node dissection for 5 cases, and pneumonectomy for 2 cases. Preoperative or adjuvant chemotherapy regimens included MVP (mitomycin C, vindesine, cisplatin), NP (vinorelbine, cisplatin), TC (paclitaxel, carboplatin), GP (gemcitabine, cisplatin), which were repeated every 4 weeks for 4-6 cycles. Total dose of radiotherapy for lesions in the lung or mediastinal field was 5000-6000cGy. Arm B (n=58): 23 cases were at stage IIIA, and 35 at stage IIIB; Median KPS was 70 (range from 60 to 90); Treatment program was the same approximately as arm A except for no operation.

RESULTSArm A: (1) Metastatic locations in follow-up, in turn, showed as: lymph node, pleural-lung, bone, brain, liver, pericardium, skin and adrenal; (2) Median survival was 27 months, and 1-, 2- and 5-year survival rate was 82.1%, 60.7% and 25.0% respectively. Arm B: (1) Metastatic locations in follow-up, in turn, showed as: lymph node, pleural-lung, bone, brain, liver, pericardium, skin, adrenal, pancreatic and esophageal metastasis; (2) Median survival was 13 months, and 1-, 2- and 5-year survival rate was 53.4%, 31.0% and 1.7% respectively. Median survival duration of Arm A was significantly superior to Arm B (P=0.0001). There were significant differences in 1-, 2- and 5-year survival rate between the two groups (Chi-Square=9.4, P < 0.01; Chi-Square=8.9, P < 0.01;Chi-Square=11.5, P < 0.01).

CONCLUSIONSCompared with non-operative multimodality treatment, operative multimodality treatment including lobectomy or pneumonectomy with mediastinal lymph node dissection can remarkably improve the survival in patients with locally advanced NSCLC.
