Application of the techniques of pedicle screw fixation in t horacolumbar spine has forcefully promoted the development of spinal surgery. Th e key to the techniques is that the pedicle screw insertion must be located into the sole exact routeway of the three-dimensional-space, that is, into the inn er vertebral body through the pedicle according to the exact arrow plane angle a nd horizontal plane angle. Recently great development has been made in the resea rch on the techniques of pedicle screw insertion in thoracolumbar spine, especia lly in the supervising means during operation. The means have been developed fro m the traditional X-ray perspective or photograph apposition to the application of computer-assisted technique. This paper reviews and discusses the current d evelopment and prospects in the research on the techniques of pedicle screw inse rtion in thoracolumbar spine.

Objective To investigate different scoring systems in predicting the severity of acute pancreatitis(AP).Methods The clinical data of 1 56 patients with AP were retrospectively reviewed.Ser-um c-reactive protein(CRP)levels were measuredat admission.According to the Chinese guidelines for the management of acute pancreatitis(2007),all the patients were categorizedas either mild acute pancre-atitis(MAP)or severe acute pancreatitis(SAP).Ranson,acute physiology and chronic health evaluation (APACHE)-Ⅱ,bedside index for severity in acute pancreatitis(BISAP),and computed tomography se-verity index(CTSI)scoring systemswere calculated according to the corresponding grading standardsin all patients.Patients were divided into MAP group(APACHEⅡ <8,Ranson <3,BISAP <2,CTSI <3 and CRP <21 .4)and SAP group (APACHEⅡ≥8,Ranson≥3,BISAP≥2,CTSI≥3 and CRP≥21 .4)ac-cording to the scoring results.ROC curve was used to compare the difference among the systems.Results Among the 1 56 patients,21 (1 3.5%)were classified as SAP and 1 35 as (86.5%)MAP.AUCs for Ranson,BISAP,APACHEⅡ,CTSI,and CRP in predicting SAP were 0.69 (95%CI:0.62-0.76),0.74 (95%CI:0.66-0.80),0.78 (95%CI:0.70-0.84),0.69 (95%CI:0.61 -0.76),and 0.68 (95%CI:0.57-0.78),respectively.There were no significant differences among these scoring systems.Conclusion There were no significant differencesin predicting the severity of AP among these scoring systems. Therefore,the early prediction of SAP should consider multiple scoring systems,and the referential signifi-cance of accessing and applying a simpler laboratory indicator deserves further studies.

Objective To understand drug use in children with common cold through comments on prescription and drug analysis,and to provide theoretical basis for standardizing medical treatment and promoting rational drug use.Methods A retrospective survey method was applied.Prescriptions of common cold in the department of pediatrics from Oct.to Dec.2015 were reviewed,and Excel 2013 was used for statistical analysis.Rationality of drug use was evaluated based onhospital prescription review management specification (try out),instructions and consensus of related experts at home and abroad.Results The utilization rate of antibacterial drugs was 93.4％in children with common cold of our hospital,utilization rate of antiviral drugs was 59.7％,utilization rate of compound cold medicine was 96.4％,and the rate of combined utilization of more than two kinds of compound medicine was 65.7％.Excessive medicine for common cold existed and abuse of cold medicine,antimicrobial and antiviral drug,irational drug combination in this hospital.Conclusion Clinical doctors lack cognition to common cold and cold medicines.Hospital pharmacy department should take effective pharmaceutical interventions to improve the level of rational drug use.

The effect on the growth and phenol degradation of the thermophilic strain BF80 by seventeen different metal ions were studied. The results showed that the metal ions certainly affected the growth and phenol degradation of the strain BF80. At the concentration of 0.01%,contrasting to the comparison,the growth and phenol degradation of the strain BF80 were restrained intensively by the metal ions of Cu2+,Zn2+,Co2+,Ba2+,Hg2+,Ni2+,Ag+,Al3+. The metal ions of Cr2+ restrained the phenol degradation of BF80 strongly while Cr2+ restrained the growth of BF80 faintly. The metal ions of Sn2+,Fe2+,Fe3+,Pn2+ restrained the growth and phenol degradation of the strain BF80 at a certain concentration,and the effect of inhibition in-creased with the increase of the concentrations of the metal ions. At the low concentration of Mn2+ or Mo2+,the growth and phenol degradation of the strain BF80 were increased,but if the concentration beyond the 0.1%,the growth and phenol degradation of the strain BF80 were inhibited. At the different concentration of Ca2+ or Mg2+,the growth of the strain BF80 were increased and the phenol degradation were accelerated,but the max rate of phenol degradation by BF80 was not influenced obviously. When the medium was added themixture of metal ions of Mo2+ and Mn2+,the strain BF80 grew better,but the rate of the phenol degradation was lower than that of single Mo2+ and Mn2+.

Intracerebral hemorrhage is a neurological emergency with high disability and mortality. Studies have demonstrated that thrombin formation,erythrocytolysis and iron ions play important roles in the brain injury after intracerebral hemorrhage. This article reviews the mechanisms of thrombin and iron ions in intracerebral hemorrhage-mediated brain injury.

Yin-Yang1 (YY1),as a ubiquitous nuclear transcription factor with double transcriptional activity in eukaryotic cells,regulates many genes transcription and plays an important role in the cellule biological processes.Overexpression of YY1 is found in several tumor types recently,and may play a role in tumor development and progression by regulating oncogenes,tumor suppressor genes,angiogenesis related factors,as well as apoptosis.YY1 may become a new kind of tumor markers,is conducive to estimate the prognosis of patients with tumor and gain important breakthrough in cancer targeted therapy.

Objective To explore the efficacy of treatment for locally recurrent rectal cancer after radical surgery. Methods In this study,the management of 107 patients with postoperative locally recurrence of rectal carcinoma admitted from August 1993 to February 2002 was retrospectively analyzed.Results Thirty-two cases were treated by reoperation combined with adjuvant therapy(group A),37 cases underwent ressction alone(group B),38 patients received adjuvant therapy alone(group C).The age of these patients was 49.3±20.7,44.4±25.4,and 52.9±29.1 respectively.The median survival time after treatment was 27.8,14.6,and 13.7 months,respectively.The five year's survival of patients in group A was better than that in group B and group C significantly(P＜0.05).Conclusions The aggressive surgery combined with adjuvant therapy improves the survival of the patients with locally recurrent rectal cancer after radical surgery.

[Objective]To study the changes of biomechanical efficiency of absorbable balloon vertebraplasty associated with pedicle screw system for treatment of thoracolumbar fracture.[Method]Six fresh adult thoracolumbar specimens were harvested and 10 segmental specimens(T_(11)~L_1、 L_(2~4)、 L_(1~3)) were processed.After burst fracture created by free-drop test,the specimens were braced and reduced by APF pedicle screw,then absorbable balloon were placed through the traumatic vertebral pedicle and were infused with autosolidification calcium phosphate cement to process vertebroplasty.The stiffness in middle vertebrae were measured under flexion,extension,lateral flexion and torsion stress before fracture and after absorbable balloon vertebroplasty respectively.[Result]The crushing strength in traumatic vertebrae after vertebroplasty with absorbable saeculi increased showed 8% under flexion,15% under extension and 9.8% under lateral flexion,but with significant increasing under extension(P0.05).[Conclusion](1)absorbable balloon vertebraplasty associated with pedicle screw system conduces to the reconstruction of traumatic vertebrae,and making postoperative spinal biomechanical characteristics approach the level before fracture;(2)Vertebroplasty with absorbable sacculus for treatment of thoracolumbar burst fracture based on the premise that avoid the potential danger induced by leakage of bone cement,and can reestablish intact corporeal structure of traumatic vertebrae and restore their height essentially,so that spinal physiologic curve can be gained to restore and maintain,tardive lumbodorsal pain and spinal cord injury and nerve injury caused by secondary kyphosis can be prevented,this can fundamentally solve complications left over by thoracolumbar burst fracture treated using pedicle screw system simply.The new method prorides a rational method for clinical treatment of thoracolumbar burst fractures.
