Objective To investigate the anterior trans-injured vertebral short segment limited fixation and fusion in treating thoracic and lumbar spinal tuberculosis.Methods One hundred and three patients with spinal tuberculosis from 2010 to 2012 were operated by trans-anterior approach(trans-thoracic above thoracic spine 12,trans-retroperitoneal below waist spine 1)tuberculosis focus clearance and spinal canal decompression,intervertebral bone graft of vertebral structure,and short segment internal fixation for residual disease spine.Results The nerve function of the patients was effectively improved after surgery,and the imaging re-sults showed that the average lesion kyphosis angle was significantly decreased(P <0.05).The postoperative follow-up found that the bone graft was fused after half a year,and the average local kyphosis angle was still 13°,which had no obvious change compared with that after operation.In addition,the internal fixation position had no looseness and fracture,the grafted bone had no displace-ment and detachment,the four limbs movement was normal without local percussion pain or tenderness.Conclusion The anterior trans-injured vertebral short segment limited fixation and fusion has the satisfactory short term clinical efficacy in the treatment of thoracic and lumbar spinal tuberculosis.

Objective To explore the effects of application of one-hand double-lumen simultaneous locking tech-nique on reduction of occlusion using high pressure resistant double-lumen PICCs. Methods Convenience sampling method was used to recruit 73 patients assigned into the experimental group,using one-hand double-lumen simulta-neous locking technique;66 patients were assigned into the control group,using routine locking method. The rate of PICC occlusion was recorded. Results The rate of incomplete occlusion was 8.22% in the experimental group,and 17.42% in the control group,the rate of complete occlusion in the experimental group was 0,and 0.76% in the control group,and the difference was statistically significant(P<0.05). Conclusion The one-hand double-lumen simul-taneous locking technique is easy and convenient to conduct. It can effectively reduce occlusion using high pres-sure resistant double-lumen PICCs.

Objective:To establish a rapid determination method of total VE in lycopene oleoresin.Method:By eliminating saponifiable matters and strong polar materials from the sample,VE was concentrated efficiently by PRP-6 SPE with 90% ethanol/water and 100% ethanol as elution solvents consecutively.The removal of polar materials was satisfactory.VE was determined by HPLC.Results:The linear regression was carried out,the relative coefficient r=0.9998 and 99.85～99.95 % recovery of VE were achieved.Conclusion:A simple and rapid VE determination method with good sensitivity is developed.

[Abstract ] Objective Evidence from previous studies indicated that over-activation of C3a/C3aR axis existed in the renal tubular epithelial cells of patients with renal diseases including diabetic nephropathy .However , the pathological significance of over-ac-tivating C3a/C3aR axis still remains to be elucidated .In this study, we constructed a renal tubular epithelial cell line over-expressing C3a in a secretory manner in order to provide a cell model to investigate the pathological significance of over -activating C3a/C3aR axis under various pathological scenes . Methods We designed a synthesized C3a secretory expression unit and cloned it into the multi-clonal site of lentivirus expression vector pLenti 6.3-MCS-IRES2-EGFP.After identification by sequencing , recombinant lentivirus was packaged by using pLenti 6.3-C3a-IRES2-EGFP and packaging plas-mid in 293T cells.Then, the recombinant lentivirus was used to in-fect HK2, a cell line of human renal tubular epithelial cells .After screening in medium with blasticidin , blasticidin resistant cell clones were obtained .Real-time PCR and ELISA method were applied to analyze the expression and secretion of stable transfected cells cloned C3a and identify renal tubular epithelial cell lines with stable over-activating C3a. Results ①C3a secretory expression unit was suc-cessfully synthesized and correctly cloned into the multi-clonal site of pLenti6.3-IRES2-EGFP; ②C3a secrectory expression recombi-nant lentivirus LV-C3a was successfully packaged with a high titer of 5 ×108/mL;③HK2 Cell clones resistant for blasticidin were ob-tained;according to the analysis of Real-time PCR and ELISA, the C3a mRNA level in HK2-C3a cell lines was significantly higher than that of HK2 cells(1.0 ±0.5 vs 1321.0 ±18.0, P<0.01) and the secreted C3a level increased significantly ([0.3 ±0.2]ng/mL vs [249.0 ±37.0] ng/mL, P<0.01). Conclusion The present study successfully constructed C 3a secretory expression vector pLenti6.3-C3a-IRES2-EGFP and C3a over-expression renal tubular epithelial cell line HK 2-C3a, which is very useful in further study of the function and significance of C 3a/C3aR axis not only in renal tubular epithelial cells but also in other cell types .

Objective To observe the changes in cardiopulmonary exercise test (CPET) variables of children with frequent premature ventricular contraction (PVC)before and after creatine phosphate treatment,to examine the difference of CPET results between PVC patients and healthy children,and to evaluate the effect of frequent PVC on the cardiac reserve function in children.Methods One hundred and nine frequent PVC children and 98 healthy children underwent treadmill exercise test and CPET respectively,the changes of CPET variables were observed among patients before and after treatment as well as among the healthy children.CPET variables include maximal oxygen consumption/kg (VO2max/kg),maximal oxygen consumption/heart rate( VO2max/HR),HR( at different time point),anaerobic threshold ( AT),and AT/VO2 maximum prediction (AT/VO2max pred).Results Before creatine phosphate treatment,VO2max/kg,VO2max/HR and AT/VO2max in frequent PVC children were ( 22.9±7.4 ) ml/( kg·min),( 9.3 ± 1.5 ) ml,( 15.5 ±2.7 ) ml/( kg· min).After creatine phosphate treatment,VO2 max/kg,VO2 max/HR and AT/VO2 max were (26.4 ± 6.0) ml/( kg· min),( 11.4 ± 3.3 ) ml,and ( 17.4 ± 3.8 ) ml/( kg· min).These CPET variables after creatine phosphate treatment in frequent PVC children were obviously higher than those before treatment and there was a significant difference [ VO2 max/kg ( t =2.11,P ＜ 0.001 ),VO2 max/HR ( t =4.02,P ＜ 0.001 ),AT( t =10.2,P ＜ 0.001 )].Control group of 98 healthy children had negative CPET results.Conclusion Cardiac reserve function decreases in frequent PVC children.After treatment,the exercise capacity and cardiac reserve function can be improved.CPET can reflect cardiac functional reserve changes in PVC children.
