Ankle sprains are orthopedic clinical common disease, accounting for joint ligament sprain of the first place. If treatment is not timely or appropriate, the joint pain and instability maybe develop, and even bone arthritis maybe develop. The mechanism of injury of ankle joint, anatomical basis has been fully study at present, and the diagnostic problem is very clear. Along with the development of science and technology, biological modeling and three-dimensional finite element, three-dimensional motion capture system,digital technology study, electromyographic signal study were used for the basic research of sprain of ankle. Biomechanical and kinematic study of ankle sprain has received adequate attention, combined with the mechanism research of ankle sprain,and to explore the the biomechanics and kinematics research progress of the sprain of ankle joint.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.

METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.

RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.

CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.

OBJECTIVETo set up a venous congested flap model to study the mechanism of necrosis through long-term microcirculation observation.

METHODSA specially deviced chamber was assembled to one side of the ears in an adult white rabbit, about 7 approximately 10 days after the operation the congested flap model was made and the microcirculatory status of the flap was dynamically observed under a vivo-microscope for a long time.

RESULTSThe venous crisis phenomenon of flap was well studied and the microcirculation of the flap was observed carefully, finally the variational rule of the congestion flap microcirculation was made clear.

CONCLUSIONSThe model could well simulate the venous crisis flap in clinic, and the microcirculation could also be observed for a long time.

To discuss the effect of environmental factors and photosynthesis on the growing of plant and the content of active components in Scutellaria baicalensis, the photosynthetic physiology index and diurnal changes of flavonoid constituent of S. Baicalensis were observed and tested in flowering and fruiting stages, and in the meantime environmental parameters were recorded. The obtained data were analyzed data by using path analysis and gray correlation analysis. The results showed that PAR and SWC were important environmental factors impacting on photosynthesis of S. baicalensis. SWC, RH and Ca were important environmental factors impacting on baicalin content. PAR, Po and Ta were important environmental factors impacting on baicalein content.

ObjectiveTo evaluate the impact of anatomic and non-anatomic liver resection on prognosisofpatientswithsmallhepatocellularcarcinoma( HCC ) usingaMeta-analysis.MethodsLiterature on anatomic versus non-anatomic liver resection for the treatment of small HCC ( ≤5 cm) was retrieved. ResultsFour nonrandomized controlled trials were included consisting of 776 patients:484 undergoing anatomic liver resection and 292 non-anatomic resection.The age ranged from 53.4 to 63.0 years.Male ∶ female ratio was 3.56 ∶ 1.87.1％ patients were Child-Pugh class A.Most patients (94.5％ ) had a single tumor.No significant differences were found conceming the 1,3,and 5 year disease-free survival rate between the two groups.There was no significant difference in overall survival and disease-free survival between the two groups at 1,3,and 5 years.Sensitivity analysis found anatomic resection was superior to non-anatomic resection in 3 year disease free survival rate (OR =0.72,95％ CI:0.52 - 0.99,P =0.04). ConclusionsAnatomic liver resection elevated the 3 year disease free survival rate of patients with small hepatocellular carcinoma when compared with non-anatomic hepatectomy but failed to further elevate long-term disease free survival and overall survival.

Objective To find out risk factors affecting the prognosis of adult cardiogenic shock patients treated with extracorporeal membrane oxygenation.Methods From January 2003 to December 2010,patients with cardiogenic shock required veno-arterial ECMO after failure of conventional therapy and intra-aortic balloon pump counterpulsation therapy were retrospectively studied. Patients with severe traumatic brain injury,advanced malignancies and multiple organ failure were excluded.All patients were divided into survival group and death group.The risk factors were found out using one-way ANOVA and a multivariate logistic regression analysis was used to determine independent factors associated with survival.Results Thirty-one patients successfully weaned from ECMO. Twenty-two patients were successfully discharged.The average duration of ECMO was 41.56 ± 43.07 hours.Factors associated with failure of hospital discharge were age,pre-ECMO levels of ejection fraction,pre-ECMO levels of lactate,disseminated intravascular coagulation,renal failure and multiorgan failure (P ＜ 0.05). Conclusions Irreversible heart failure and the complications are significantly correlated with survival,and the early use of ECMO for cardiogenic shock and recognize the factors are key to the success of ECMO treatment.

Objective To construct the prostate-specific double gene expression vector pIRESPSMAe/p-TK-Cx43 and establish the foundation for experimental prostate cancer gene therapy research. Methods Cx43 gene was amplified and cloned into pMD19-T Simple vector. HSV-TK gene was then synthesized and cloned into multiple clone site (MCS) A of the eukaryotie vector plRES. The new plasmid was named plRES-TK: PSMAe/p was obtained and cloned into plRES-TK by replacing CMV promoter. The new plasmid was named plRES-PSMAe/p-TK; Fourth, Cx43 gene was cloned into the MCS B of pIRES-PSMAe/p-TK and the new plasmid was named pIRES-PSMAe/p-TK-Cx43.This plasmid was identified by double digestion with Sal Ⅰ/Not Ⅰ and sequenced; Finally, LNCaP cells were transfected by the plasmid plRES-PSMAe/p-TK-Cx43 and the mRNAs expression of HSV-TK gene and Cx43 gene was tested by RT-PCR. Results The plasmids synthesized in this experiment were double digested respectively and the specific bands of the inserted genes were confirmed by RTPCR. plRES-PSMAe/p-TK-Cx43 was in line with the expected design by DNA sequencing. The mRNAs of TK gene and Cx43 gene were expressed and successfully confirmed by RT-PCR after LNCaP cells transfected with pIRES-PSMAe/p-TK-Cx43. Conclusion Double gene expression vector pIRES-PSMAe/p-TK-Cx43 containing HSV-TK gene and Cx43 gene is constructed successfully.
