[Objective]To study the role and the effect of establishing the plan of meeting emergency in the rehabilitation and reestablishment of high-octane body hurt.[Method]Eighty six patients of high-octane body hurt were collected from Shi He Zi people's hospital during 1998 to 2007.According to Gustilo-Anderson categorize of open fracture and mark of ISS,high-octane body hurt can be divided into three parts.Meanwhile,different part can be taken different methods to rehabilitate and reestablish.Therefore,we can analyze pertinence between cure principle and curative effect.[Result]Eighty three patients were observed during the period of fifteen and thirty-three months,the average were nineteen months.Five of them contracted double floating knee injury,and their knee joint appeared anchylosis,abnormality and function failure afterfracture healed up.We did one-off knee joint release while extracting internal fixation,and used CPM machine to assist exercise.Fortunately,the function of knee joint could be renewed.Another five patients' fracture did not heal up very well.However,after experiencing the apply of oneself bone autograft,fracture could be healed up perfectly.The time of allograft bone union ranged from five to sixteen months,the average time were 7.5 months.There are three patients contract paraplegia,and three patients dead.By autopsy,some of them belongs to multiple fracture and multiple viscera burst.Mortality was 3.48%.[Conclusion]By establishing the plan of meeting emergency of high-octane body hurt,using the Gustilo-Anderson categorize of open fracture and mark of ISS,we can systemic classify damage degree,and make scientific treatment by stages,therefore,attaining our goal of early diagnoses,early treatment,and decreasing mortality and decreasing the proportion of disabled.After all,the plan of meeting emergency plays an essential role in traumatie surgery.

[Objective]To detect the expression of tumor necrosis factor-?(TNF-?)and interleukin-18(IL-18)protein in herniated intervertebral disc,and discuss the role of TNF-? and IL-18 protein in the course of the intervertebral disc degeneration and to clarify the mechanism of the lumbar intervertebral disc degeneration and herniation. [Method]Forty nine specimens were studied from December 2005 to April 2007 in the First Affiliated Hospital of Shihezi Medical College.Experimental group contained thirty-four herniated intervertebral disc and control group contained fifteen discs,which were collected from the patients with spine fracture or autopsy.The specimens were divided into two parts,one part was fixed in 10% formalin about 24 hours and was embedded in paraffin.Four ?m serial sections and S-P method were used.The sections were stained with TNF-? and IL-18 monoclonal antibodies,and the results were observed by OLYMPUS microscope.Another part was changed into well-distributed liquid,which was determined by Elisa method respectively,in order to detect density of TNF-? and IL-18 protein.Software SPSS 13.0 was used for statistical analysis.[Result]1 TNF-? and IL-18 protein were expressed mostly in cytoplasma.The expression of IL-18 in the experiment group was obviously higher than in the control group.There were statistical significances(P

BACKGROUND:As for patients with one-side backleg pain who were candidates for surgery treatment of lumbar intervertebral disc herniation, the common treatment includes lumbar vertebral plate opening and decompression, and laminectomy in combination with compression and bilateral pedicle screw fixation. However, these therapeutic approaches are not satisfactory. OBJECTIVE:To explore the feasibility and efficiency of single-side lumbar interbody fusion and unilateral pedicle screw fixation for treatment of lumbar intervertebral disc herniation patients with one-side backleg pain. METHODS:Forty patients with single-side lumbar disc herniation, suffering from unilateral backleg pain, were recruited from Shihezi People’s Hospital, China and were treated with single-side lumbar interbody fusion and unilateral pedicle screw internal fixation. The neurological function of patients was assayed using Japanese Orthopaedic Association score system before and after treatment, the improvement rate and excellent/good rate were calculated. Suk criterion was used to determine fusion status. RESULTS AND CONCLUSION:The mean fol ow-up period for 40 patients was ranging from 6 months to 60 months. Al incisions healed wel , with no infection. The Japanese Orthopaedic Association score after 6 months of treatment was significantly higher than that before treatment (P<0.05), with the excellent and good rate up to 88%. According to Suk criterion, 38 patients achieved bone graft fusion or possible fusion, with interbody fusion rate 95%, as revealed by radiographic and CT evidence. The remaining two patients were detected fusion at 9 months after treatment. Our findings indicate that, single-cage lumbar interbody fusion combined with single-side pedicle screw fixation is the feasible surgical technique and provides satisfactory effects in treating single-side lumbar disc herniation.

The yeast Sacchromyces cerevisiae is most widely used for producing bioethanol in alcoholic industry due to its higher ethanol yield and fermentation rate. However, the toxic effect of accumulated ethanol is one of the main factors, which limit high ethanol production. Thus, investigating the mechanisms of yeast ethanol tolerance will provide the basis for solving the industrial problem. This article reviewed the mechanisms of Sacchromyces cerevisiae ethanol tolerance focusing on its cell physiological behaviors, structure and biochemical composition, as well as its genetic basis.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

Objective To assess left ventricular function early and late improvement of patients with acute myocardial infarction (AMI) treated by percutaneous coronary intervention (PCI) by speckle tracking imaging (STI).The clinical values of the assessment of STI for the prognosis and heart function improvement of AMI patients treated by PCI were discussed.Methods 73 AMI patients who had AMI for the first time and had been treated by primary PCI from September 2010 to July 2011 and were examined in the follow-ups from December 2010 to February 2012 in our hospital were enrolled.Dynamic images were acquired before PCI,at 3 months and 6 months after PCI and analyzed by STI.Dynamic images were analyzed for longitudinal peak systolic strain (LPSS),radial peak systolic strain (RPSS) and circumferential peak systolic strain (CPSS) values by STI.According to the comparison of left ventricular ejection fraction (LVEF) before PCI and 6 months after PCI,patients were divided into left ventricular function improved group (ΔLVEF6＞5％) and not-improved group.According to the comparison of LVEF before PCI and 3 months after PCI,improved group were divided into left ventricular function early-improved group (ΔLVEF3 ＞5％) and late-improved group.Results The values of all STI parameters before PCI,3 months and 6 months after PCI in improved group were higher than those in not-improved group (P ＜0.001,all).LPSS before PCI and at the follow-ups and RPSS at 3 months after PCI in early-improved group were higher than those in late-improved group (LPSS at 3 months after PCI:P＜0.001;Other parameters:P ＜0.05).There were significant correlations between all STI parameters and both ΔLVEF3 and ΔLVEF6.LPSS before PCI was more closely related to ΔLVEF3 (r =-0.781,P ＜0.001).CPSS at 6 months after PCI was more closely related to ΔLVEF6 (r =-0.834,P ＜ 0.001).Conclusions Early and late function improvement of left ventricle in AMI patients who is treated by PCI are accurately assessed by STI.The precise analyses of longitudinal and circumferential movements in STI are important for clinical diagnosis.

Objective To evaluate left atrial function in patients with ischemic cardiomyopathy(ICM)and dilated cardiomyopathy(DCM)by two dimensional-speckle tracking imaging(2D-STI).Methods Twenty-two patients with ICM,twenty-six with DCM and thirty-two healthy subjects were studied.The maximum volume(LAVmax),minimum volume(LAVmin)and volume before the systole(LAVp)of left atria were acquired using biplane area-length method,and calculated the total emptying volume(LATV),expansion index(AEI),active emptying volume(LAEV)and fraction(LAEF)of left atria.The strain and strain rate during systole and late of diastole(Ss,SRs,Sa and SRa)were measured at each left atrial wall (septal,lateral,anterior and inferior).The average of them were worked out.The correlation of left atrial function and strain rate were analysed.Results ①No significant differences were found at the age,sex,heart rate and the E wave between the mitral leaflet tips during all the groups.Compared with the control group,the peak of A wave,the deceleration time of E wave and LVEF decreased in ICM and DCM groups,while the LAD,LVEDD and E/A increased significantly in the two groups(P＜0.05).There were no significant differences between ICM and DCM.②Compared with the controls,the LAVmax increased,AEI and LAEF decreased significantly in patients with ICM and DCM,even lower in DCM(p＜0.05).③Compared with the controls,the Ss,SRs,Sa and SRa reduced significantly in patients with ICM and DCM(P＜0.05),and the DCM showed much significant differences than ICM(P＜0.05).④The AEI had a positive correlation with SRs(r =0.765,P＜0.01).The LAEF had a significant correlation with SRa(r =0.830,P＜0.01).Conclusions The accumulation during systole and active emptying function during late of diastole are both lower in ICM and DCM,even worse in the latter.The 2D-STI may paly an important role in the evaluation of left atrial function.

Objective To evaluate the function and synchronization in patients with paroxysmal atrial fibrillation(PAF) by two dimensional speckle tracking imaging(2D-STI) measuring the strain of left atrial.Methods Thirty healthy controls and thirty-five patients with PAF were studied.The PAFs were divided into group PAF1 during the diapause and group PAF2 during the stage of attack.From the strain-time curve of 2D-STI workstation,the peak velocity(Vs,Ve and Va),the peak amplitude of longitudinal strain (Ss,Se and Sa) and strain rate (SRs,SRe and SRa) were acquired in the course of systole,the early and the late diastole respectively.The synchronization of left atrial (Ts-SD,Te-SD and Ta-SD) could be gotten from the time to the peak strain.The correlation were analysed between the synchronization indices and the strain rate parameters.Results ①No significant differences were found at the age,heart rate,E/A,IVS,LVEDD and LVEF.Compared with the control group,the LAD increased and DT decreased in PAF1 and PAF2 groups (P ＜0.05).②The peak velocity were slower,the peak strain were shorter and the peak strain rate were lessened in the PAFs than the controls(P ＜0.05),except the SRa(P ＞0.05).③The Ts-SD and Te-SD were much more different during the three groups(P ＜0.05),the PAF2 showed fewer synchronization; the Ta-SD was higher in the PAF1 than the controls(P ＜0.05).④The Ta-SD had a positive correlation with SRa(r =0.61,P ＜0.01).Conclusions The reservoir and conduit function of left atrial are impaired in PAFs during the diapause,the booster pump could recover partially,however,there are dyssynchronization.The booster pump function disappear during the stage of attack and there are worse synchronization.2D-STI may paly important roles in the assessment of function and synchronization of left atrial.

Objective To assess the left ventricular function of patients with acute myocardial infarction (AMI) treated by percutaneous coronary intervention (PCI) by speckle tracking imaging (STI).Methods 75 AMI patients who had AMI for the first time and have been treated by primary PCI were enrolled.Dynamic images were acquired before PCI,at 6 months after PCI and analyzed by STI.Dynamic images were analyzed for longitudinal peak systolic strain (LPSS),radial peak systolic strain (RPSS) and circumferential peak systolic strain (CPSS) values by STI.According to the comparison of left ventricular ejection fraction (LVEF) before PCI and 6 months after PCI,patients were divided into left ventricular function improved group (△LVEF≥5％) and not-improved group.Results Compared to non-improved group,LPSS (P ＜0.001),RPSS (P ＜0.05,P ＜0.001) and CPSS (P ＜0.001) of improved group were all higher before and 6 months after PCI.LPSS (r =-0.578,P ＜0.001) and CPSS (r =-0.817,P ＜0.001) before PCI were both closely related to △LVEF.In single parameter mode of ROC curve analysis,the area under the ROC curve (AUC) (0.867),sensitivity (94.7％) and specificity (74.4％) of CPSS are relatively higher than other STI parameters.In multiple parameters united mode of ROC curve analysis,AUC (0.897),sensitivity (94.7％) and specificity (74.4％) of LPSS,RPSS and CPSS united were the highest among all the combinations of all STI parameters.Conclusions Left ventricular function improvement of patients with AMI 6 months after PCI is accurately assessed and predicted by STI.CPSS is a strong predictor for left ventricular function improvement 6 months after PCI of AMI patients among all the STI parameters and is an effective indicator for the assessment of left ventricular function improvement of AMI patients.
