Objective To compare the clinical curative effects of balloon vertebroplasty reinforced by injectable calcium sulfate cement(CSC) and posterolateral fusion after short-segment pedicle screw fixation through the fractured vertebra in treatment of thoracolumbar bumt fractures.Methods From February 2012 to May 2015,68 cases patients with single thoracolumbar burst fracture were admitted in Orthopaedics and Traumatology Department of Traditional Chinese Medicine Hospital of Gaozhou,and were randomly divided into two observation group and control group,each group with 34 cases.Observation group were treated by short-segment pedicle screw fixation through the fractured vertebra followed by transpedicular balloon reduction of the endplate and CSC injection,the control group were underwent posterolateral fusion in addition to short-segment pedicle screw fixation through the fractured vertebra.The 2 groups were compared at preoperation,and the last follow-up in terms of visual analog pain score(VAS),Oswestry disability index(ODI),anterior height ratio of the injured vertebra,middle height ratio of the injured vertebra,the vertebral wedge angle and the sagittal Cobb angle.Results The patients were followed up from 12 to 54 months.All the measure indexes at the last follow-up were significantly improved than those at preoperation in all the patients(P<0.05),there was no significant between two groups difference in the VAS score or ODI at last follow-up(P>0.05).At the last follow-up,the observation group showed a significantly less loss than the control group regarding the corrections of anterior height ratio of the injured vertebra((93.6±3.4) vs.(81.8±4.8)),middle height ratio of the injured vertebra((90.7±3.8) vs.(78.9±5.1)),the veaebral wedge angle((5.7±1.9) ° vs.(8.8±3.0) °) and the sagittal Cobb angle((5.2±2.1) ° vs.(7.9±2.4) °)(t=4.143,5.786,4.819,4.465,P<0.05).Conclusion In treatment of thoracolumbar burst fractures,compared with posterolateral fusion,balloon vertebroplasty reinforced by injectable CSC can better restore the shape of injured vertebral body and stability of the anterior and middle columns in the early period,can also reduce losses of corrections,and keep the function of the spinal motion segment.

Objective To investigate the expression and sensitivity of 6 muhidmg resistance gene products(MDR) : GST-π、LRP、MRP、Topo Ⅱ、P-gp、TS in gastric cancer during neoadjuvant chemotherapy. Methods Expression of the 6 muhidrug resistance gene was detected by immunohistoehemistry in 35 cases of stomach cancer tissues before and after neoadjuvant chemotherapy. The relationship between muhidrug resistance gene and neoadjuvant chemotherapy was analyzed. All patients were given FOLFOX4, and the effects were evaluated according to World Health Organization criteria. Results The overall response rates to chemotherapy was 46%, expression of the 6 mtdtidrug resistance gene in 35 cases of stomach cancer tissues were as follows:GST-π was 40% ,LRP was 69% ,MRP was 34% ,Topo Ⅱ was 37% ,P-gp was 86%, TS was 40%, expression of the 6 muhidrug resistance gene did not change during neoadjuvant chemotherapy; GST-π、LRP、MRP、Topo Ⅱ、P-gp were not correlated with chemotherapy sensitivity(P > 0.05), while TS was significantly correlated with chemotherapy sensitivity (P = 0.0048). Conclusion FOLFOX4 does not effect a change in the expression of the 6 muhidrug resistance gene: GST-π、LRP、MRP、Topo Ⅱ、P-gp and TS, while TS is significantly correlated with gastric cancer chemotherapy sensitivity.

BACKGROUND:Kyphotic deformity in ankylosing spondylitis is the flexion deformity of spine sagittal plane in the late lesion. Spinal osteotomy is the only treatment method in patients with severe wheel-like kyphosis. For thoracic and thoracolumbar ankylosing spondylitis patients with lumbar severe wheel-like kyphosis, osteotomy at a single site cannot obtain safe and effective orthopedic effect. OBJECTIVE:To observe the orthopedic effect of total spine osteotomy combined with V-shaped osteotomy for correction of severe wheel-like kyphosis deformity due to ankylosing spondylitis, and to analyze stress distribution. METHODS:From May 2003 to October 2012, total spine osteotomy combined with V-shaped osteotomy and pedicle screw fixation were adopted for repair of concurrent thoracic, thoracolumbar and lumbar severe wheel-like kyphosis deformity due to ankylosing spondylitis in 36 male cases in the Sixth Affiliated Hospital of Xinjiang Medical University. Spinal convex angle, chin-brow vertical angle and C 7 plumb line were measured to evaluate orthopedic effect. RESULTS AND CONCLUSION:The whole spine convex Cobb angle was corrected from preoperatively (89.6±9.8)° to (32.2±6.7)° at 1 week after treatment, showing significant difference (P<0.05), with an average correction rate of 64%. The chin-brow vertical angle was 9.6° averagely after correction (P<0.05), with an average correction rate of 76%. The C 7 plumb line was 4.4 cm averagely after correction (P<0.05), with an average correction rate of 81%. After fol ow-up of 24-48 months, no significant difference in above indexes was detected during final fol ow-up and 1 week postoperatively (P>0.05). Radiographs demonstrated that fixation position was good in al patients. These results confirmed that in patient with severe wheel-like kyphosis deformity due to ankylosing spondylitis, the application of total spine osteotomy combined with V-shaped osteotomy is a safe and effective method, can better correct the spinal sagittal curvature and reduce the risk of sagittal angle, result in the stress distribution in many segments and the shortening of the spine and epidural buckling in relatively long segment, can avoid nerve damage induced by spinal cord shortening and epidural excessive buckling within short segment.

Objective To compare recent curative effect between double Endobutton technique and clavicular hook plate (CHP) in patients with Tossy grade Ⅲ acromioclavicular separation.Methods One hundred and forty-nine patients with Tossy grade Ⅲ acromioclavicular dislocation were divided into control group (78 cases,treated with CHP) and observation group (71 cases,treated with double Endobutton technique) according to treatment method.The postoperative injured shoulder visual analogue score (VAS),abduction-rise activity and flexion-rise activity,Constant-Murley score and Karlsson grade were compared between 2 groups.Results All the patients successfully completed the operation,and the postoperative follow-up time was 9-40 (15.8 ± 5.2) months.The injured shoulder abduction-rise activity and flexion-rise activity postoperative 9 months in observation group were (100.9 ± 13.3)° and (131.6 ± 13.4)°,in control group were (81.4 ± 8.4)° and (96.7 ± 10.9)°; the injured shoulder VAS in observation group and control group were (2.2-± 0.8) and (3.0 ± 0.9) scores,and there were statistical differences between 2 groups (P ＜ 0.01).The Constant-Murley score in observation group and control group were (85.4 ± 6.4) and (82.5 ± 6.2) scores,the excellent and good rate of Karlsson grade in observation group and control group were 84.5％(60/71),91.0％ (71/78),and there were no statistical differences (P ＞ 0.05).Conclusions The recent curative effect of double Endobutton technique and CHP in patients with Tossy grade Ⅲ acromioclavicular separation is similar.

AIM: To investigate killing effect of herpes simplex virus thymidine kinase/ganciclovior system(HSV-TK/GCV) on osteosarcoma cell and its mechanisms.METHODS: Recombinant retroviral vector (DORHyTK) containing hygromycin phosphotransferase-thymidine kinase fusion gene(HyTK) was constructed and introduced into human osteosarcoma cell line OS732 with DOTAP. DNA and total RNA extracted from HyTK expressing cells (OS732TK) were tested by PCR and RNA dot blot analysis. A chemosensitivity of OS732TK cells to GCV and “bystander effect” were measured by means of MTT colorimetric assay. Hoeschst 332258 staining and flow cytometric analysis were performed for mechanism of HSV-TK/GCV system gene therapy. RESULTS: DORHyTK was constructed successfully; the HyTK gene existed and expressed in OS732TK cells; All OS732TK cells were killed after 5 days of exposure to 5 mg/L GCV. The “bystander effect” was observed in both a high population and a low population, but the former was stronger than the latter. Hoeschst 332258 staining revealed the characteristic hallmarks of apoptosis, however necrosis also existed. Flow cytometric analysis of DNA content showed a G0-G1 phase blockade. CONCLUSION: HSV-TK/GCV gene therapy system showed its strong killing effects on osteosarcoma cells OS732; The phenomenon of “bystander effect” was also very apparent. GCV exposure induced both necrotic and apoptotic death in HSV-TK expressing cells, and perturbed the cell cycle. HSV-TK/GCV gene therapy system may provide a new therapeutic approach for treatment of osteosarcoma.

AIM:To detect and compare the longitudinal mitral annulus diastolic velocity and time interval changes by pulsed Doppler tissue imaging(DTI)in patients with angina pectoris(AP)and myocardial infarction(MI),and to explore the value of mitral annulus diastolic velocities and time intervals for evaluation of global left ventricular diastolic dysfunction.METHODS:Fifty patients with established coronary artery disease were divided into AP group(16 cases)and MI group(34 cases).Sixteen age-matched healthy individuals served as the control group.The septum,lateral,anterior and inferior walls of the mitral annulus were displayed,and selected for DTI spectrum sampling.Peak early and late diastolic velocities and their ratio,time to the onset and peak of the early diastolic wave,and regional isovolumic relaxation time were measured,and the average values of the four mitral annular sites were calculated and presented as Em,Am,Em/Am,QEm,TEm and IVRTm,respectively.RESULTS:Compared with the control group,Em and Em/Am were significantly lower in both the AP and the MI groups(P＜0.01).Em was even lower in the MI group than that in the AP group(P＜0.01).QEm,TEm and IVRTm were significantly longer in the AP and the MI groups than those in control group(P＜0.01 or P＜0.05).IVRTm was even longer in the MI group than that in AP group(P＜0.01).IVRTm had significantly negative correlation with Em(r=-0.64,P＜0.01).CONCLUSION:Em,Em/Am,QEm,TEm and IVRTm as measured by pulsed DTI may be promising indexes for quantitative assessment of global left ventricular diastolic dysfunction in patients with coronary artery disease.Em and IVRTm may indicate the severity of ischemic myocardial damage.

Objective To investigate changes in symptoms and quality of life (QOL) score before and after transurethral resection of the prostate ( TURP), and their related factors. Methods Forty-seven elderly male patients of benign prostate hyperplasia (BPH) with lower urinary tract symptoms were enrolled in the study, with an average age of 72 years. They all were undergone with TURP and evaluated with international prostate symptoms score (IPSS), QOL score, maximal urine flow rate (Qmax), residual urine volume, pressure-urine flow rate and prostate size before and after the procedure. Changes in these parameters and their related factors were analyzed. Results No complication was observed during TURP in the 47 patients. After TURP, two patients suffered from distal urethra stricture, one from retrograde ejaculation and six from aggravated urgent incontinence, and symptoms relieved with symptomatic treatment in all of them. Significant difference in overall IPSS, irritant score and obstructive score pre- and post-operation was observed P ＜ 0.01, i. e. , 22.7 ±4.9 and 10.5 ± 5.8, 10.5 ± 5.8 and 6.3 ± 3.5, and 12.1± 3.9 and 4.2 ± 3.3, respectively. QOL score was 4.6 ± 0.9 and 2.3 ± 1.3, Qmax (5.8 ± 2.9 ) ml/s and (12.4 ±5.2) ml/s and residual urine volume (99 ± 16) ml and (34 ± 19) ml pre- and post-operation,respectively ( all P ＜ 0.01 ). Follow-up time after the procedure, prostate volume and bladder volume at urgent urination desire all correlated with post-operation IPSS ( r = 0.751, P ＜ 0.05 ), and follow-up time after the procedure and age also significant correlated with post-operation QOL score (r = 0.470, P ＜ 0.05 ).Conclusions Overall IPSS, irritant score, obstructive score and QOL score improved significantly after TURP in symptomatic BPH patients, probably by varied related factors.
