Objective To explore the clinical value of measuring solubie serum CD44 variant 6sCD44v6 in patients with colorectal cancer. Methods Serum leves of sCD44v6 and CEA in96 patients with colorectal and in 24 healthy indivduals were detected by ELISA andchem-iluninesenle immunoassoly,respectively.Some ehnieal pathological indexes were analyzed.Results Mean sCD44v6 level in patients with colorectal cancer was 275.3+-115.8 ng/ml,which was significantly hirher than that in healthy controls(61.3+-7.8 ng/ml,P＜0.05).When using the mean+2s sCD44v6 level of healthy controls as the cut-off value,sCD44v6 level were abnormally elevated in 71 of 96(73.96%)patients with coloreeatal cancer.Conclusion The sCD44v6 leveland positive rate also increased with Dukesstage and tumor metastasis Compared with serum CEA level,the sCD44v6 level might reflect the tumor invasion and metastasis more directly and sensitively.

Objective To observe the effect of sling exercise therapy on nonspecific low back pain. Methods 35 cases with nonspecific ow back pain in community were divided into treatment group (n=18) and control group (n=17). All the cases accepted electrotherapy and hose in the treatment group accepted sling exercise in addition for 4 weeks. Before and after treatment, the cases were assessed with Numeric ain Rating Scale (NRS) and Oswestry Low Back Pain Disability Questionnaire. Results The scores of NRS and Oswestry Low Back ain Disability Questionnaire both improved more in the treatment group than in the control group (P<0.05). Conclusion Sling exercise can elieve the pain and disability from nonspecific low back pain in community.

ObjectiveTo explore the relationship between rotary strength of trunks and stability of the low back in patients with nonspecific low back pain. MethodsBefore sling exercise therapy (SET), 22 patients with chronic nonspecific low back pain were measured the rotary strength of core muscles of trunks with Proxomed Tergumed functional spinal evaluation and training system and the core stability of the low back with SET system. Their correlation was analyzed. ResultsThe core rotary strength was positively correlated with the local stability in patients with chronic nonspecific low back pain (r=0.876, P<0.001). ConclusionIncreasing the rotary strength of trunks is important to improve local stability in patients with chronic nonspecific low back pain.

Objective To research the incidence rate,potential etiologic factors,treatment of complications in patients with acute spinal column and spinal cord injury.Methods The date of 543 patients with acute spinal column and spinal injury were analyzed retrospectively.Results Of 543 patients,242 cases(44.6%)had complications.The first to third complications were hyponatremia(202 cases,37.2%),urinary tract infections(150 cases,27.6%)and pulmonary infections(54 cases,9.9%)respectively.The incidence rate of hyponatremia and pulmonary infections in patients with complete cervical spinal cord injuries increased obviously.Conclusion Early rehabilitation and active prevention can prevent the complications in patients with acute spinal column and spinal cord injury.

Objective To summarize the experience in the treatment of ankylosing spondylitis with spinal fracture and spinal cord injuries. Methods The treatment and results of 12 patients with ankylosing spondylitis with spinal fracture and spinal cord injuries were reviewed and compared. Results and Conclusions We emphasize that the treatment of complications, especially pneumonia, is very important. Conservative treatment may be used at first, but the patients with surgical indications should be operated early.

ObjectiveTo define the occurrence rate,time course, potential etiologic factors, treatment and prognosis of hyponatremia in patients with actue spinal cord injury.Methods99 patients who were admitted with hyponatremia after acute spinal cord injury were analysed retrospectively. ResultsAll these patients could concluded into three types:type I were mostly the patients with thoracic and lumbar spinal cord injury,whose mean lowest serum natrium concentration (MLSNC) were (128.6±6.6)mmol/L,continued (8±5.3)days,and it could be recovered after two weeks by accurate supply natrium and/or fluid restriction.Type II included the patients with cervical spinal cord injury,whose MLSNC were(125.1±6.0)mmol/L, continued(26.7±17.0)days,mean uric natrium concentration were 200mmol/24h,and poorly responded to the therapy of supply natrium.Type III also included the patients with cervical spinal cord injury, whose MLSNC were (118.3±9.4)mmol/L, continued (36.8±5.4)days, uric natrium concentration were 200-400mmol/24h, urinary volume had been above to 4000ml for 4 weeks.The serum natrium concentration would decrease after supply natrium therapy,but would recover.after fluid restriction. ConclusionsThe hyponatremia in patients with actue spinal cord injury sould be treated according to different type.

Objective To establish z-score model for fetal tricuspid annular plane systolic excursion(FAM-TAPSE) and mitral annular plane systolic excursion(FAM-MAPSE) based on gestational age(GA),then to evaluate the ventricle systolic function of fetus with heart failure.Methods One thousand and twelve normal fetuses and 24 fetuses with heart failure were involved. FAM-TAPSE and FAM-MAPSE were measured by free angle M-mode echocardiography,and FAM-TAPSE and FAM-MAPSE z-score models of normal fetuses were constructed by using first standard regression analysis with GA as independent variable.The fetuses with heart failure were divided into left heart failure (LHF) group and right heart failure (RHF) group by Tei index.Subsequently,the two parameters between normal and fetuses with heart failure were compared. Results The models used to calculate z-score for FAM-TAPSE and FAM-MAPSE were constructed,and GA had close correlation with them. Compared with normal fetuses,the mean z-scores of FAM-TAPSE and FAM-MAPSE were statistically different in fetuses with heart failure(P<0.001). The FAM-MAPSE z-scores of LHF and the FAM-TAPSE z-scores of RHF were all less than-2 z-scores.Conclusions The FAM-TAPSE and FAM-MAPSE z-scores decline in fetuses with heart failure and they can provide quantitative evidence in evaluation of heart systolic function,FAM-TAPSE and FAM-MAPSE z-score would be markers for assessing heart systolic function in fetuses with heart failure.

Objective To obtain the annular plane systolic excursion difference (APSED)of fetuses in second and late trimester by free angle M-mode (FAM)and tissue motion of annular displacement (TMAD)in order to assess the fetal ventricular function.Methods The mitral annular plane systolic excursion(MAPSE)and tricuspid annular plane systolic excursion(TAPSE)of four hundred and fifty five normal fetuses from 20 to 41 weeks were measured by FAM echocardiography,and the difference between them were calculated.Early diastolic velocities (Em)of the mitral annular and early diastolic velocities (Em')of the tricuspid annular were estimated by pulsed-wave tissue Doppler imaging (TDI),meanwhile systolic velocities (Sm)of the mitral annular and systolic velocities (Sm')of the tricuspid annular were also estimated by TDI.Fifty normal fetuses in the second and late trimester were choosed randomly,two-dimension imaging was obtained at the apical four-chamber view,then mitral annular plane and tricuspid annular plane displacement curve were acquired at the same time by using off-line QLab 8.1 software,and the differences in the peak time between them were compared.The trace of annular displacement were recorded by color tissue tracking technology.Results There was a significant difference between FAM-TAPSE and FAM-MAPSE in different gestational weeks (P <0.05),FAM-TAPSE was growing with the increase of gestational weeks,FAM-APSED showed significant positive correlations with gestational week, Em,Sm,Em' and Sm'.Annular plane displacement curve showed that TMAD-TAPSE was higher than TMAD-MAPSE in the entire cardiac cycle,and there was no statistically significant difference in time to peak of the annular plane displacement curve between them(P >0.05).Conclusions The APSED existed in the second and late trimester continually.It was considering associated with fetal ventricular torsion.As the growth of gestational weeks,the increase of APSED reflected the enhanced reserve capacity of the fetal ventricular torsion.APSED can reflect the longitudinal motion and torsion movement of fetal ventricle quantitatively,and can be used as a new index to assess the fetal cardiac function.

Objective To develop Z-score reference ranges for tricuspid annular plane systolic excursion(TAPSE) in normal fetuses from the measurements of gestational age(GA),biparietal diameter (BPD) or femur length(FL) using fetal echocardiography.Methods A retrospective cross sectional study of 1012 singleton normal fetuses were performed.The gestation age ranged from 20 to 41 weeks.Non-cardiac fetal biometric parameters included GA and BPD and FL were measured and calculated GA based on menstrual age.TAPSE was measured in a standard apical four-chamber view by free angle M-mode echocardiography.Normal Z-score ranges were developed for TAPSE using GA,BPD and FL as independent variables.These were accomplished by using first standard regression analysis and then weighted regression of absolute residual values for each parameter in order to adjust for inconstant variance.Results Linear regression model was the best description of the data in each case and correlations between TASPE and independent variables (GA,BPD,FL) were excellent.Heteroscedasticity of standard deviation (SD) with increasing independent variables also could be modeled with a simple linear regression.According to these equations,TAPSE Z-score =(the actual measurement of TAPSE-predicted TAPSE)/prediction SD.Conclusions Normal reference ranges and Z-scores for TAPSE have been provided.These normative data may be useful tools for assessment of fetal TAPSE,to evaluate fetal right ventricular function more accurately and effectively.

ObjectiveTo assess different treatments on nonspecific low back pain.Methods246 subjects were assigned to 3 groups, a control group(n=82), a home exercise group(n=82) or a strengthening exercise group(n=82). Follow-up data were obtained at 1 months, 3 months and 6 months after the treatment. Primary outcome measures were modified Oswestry Low Back Pain Disability Questionnaire for disability and Numeric Pain Rating Scale for pain.ResultsThe home exercise and strengthening exercise groups experienced greater improvements in disability than the control group 6 months after the treatment. The strengthening exercise group demonstrated greater change than home exercise group.ConclusionActive rehabilitation therapy may benefit nonspecific low back pain patients.
