Objective To observe the protective effect of?-asarone,the active components from Rhizoma Acori Tarinowii,on human umbilical venous endothelial cell strain ECV304 injury induced by oxidized low-density lipoprotein(ox-LDL)and to investigate its influence on proliferation of vascular smooth muscle cells(VSMC). Methods The well-grown ECV304 cells were randomized into 5 groups:normal group,control group,high-, middle-and low-dose?-asarone groups.Except the normal group,ECV in the other groups were co-cultured with ox-LDL 25?g/mL,and the?-asarone groups were additionally with?-asarone 30,15 and 7.5?g/mL added respectively.Flow cytometry was used to detect the cell apoptotic rate and the mitochondrial membrane potential (MMP)of ECV304 as well as the proliferation index and the DNA content in different cell phases of VSMC. Results In the model group,the apoptotic rate of ECV was increased,MMP was decreased,and VSMC proliferation was promoted(P

Objective The purpose of this study is to assess the prognostic significance of over expression of P53, C-erbB-2 in breast cancer. Methods In 48 patients with breast cancer the expression of P53, C-erbB-2, PCNA and ER was determined by the S-P staining immunohistochemical technique. Results The positive rate of P53, C-erbB-2, PCNA and ER were 54％, 43.7％ 52％, 41.6％ seperateiy. Expression of P53 and C-erbB-2 increased with the class of the tissuess. There is significant difference between grade Ⅰ and Ⅱ , Ⅲ (P＜0.05) as well as between lymph node metastasis (＋) and lymph node metastasis (-) patients (P＜0.05). Conclusion The over expression of P53, C-erbB-2 may be a useful prognostic indicator in breast cancer.

Objective:To explore value of 256-slice spiral CT pulmonary artery angiography (CTPA)evaluating right heart function in patients with acute pulmonary embolism (APE).Methods:According to death risk assessment of APE patients, a total of 67 APE patients were divided into high risk APE group (n=41)and non-high risk APE group (n=35).CTPA was used to analyze and compare CTPA obstructive index and right heart function indexes between two groups.Correlations among CTPA obstructive index and right heart function indexes were also analyzed.Results:Compared with non-high risk APE group,there were significant rise in CTPA constructive index [8.58% vs.24.69%],percentages of straight or left protruded ventricular septum (31.46% vs.73.17%)and bronchial artery dilation (5.71% vs.24.69%);Except the supe- rior vena cava diameter,the rest right heart function parameters had difference significance in two groups,P<0.05 or<0.01. Spearman correlation analysis indicated that CTPA obstructive index was significant positively correlated with right ventricular maximal short axis (RVMSA),RV:LV,diameters of main pulmonary artery,superior vena cava and azygos (r=0.684~0.954),and significant inversely correlated with LVMSA (r=-0.786),P<0.01 all.ROC curve analysis indicated that AUCs of CTPA RV:LV (0.949)was the biggest diagnosing APE severity.Conclusion:Right heart func- tion indexes measured by multi-detector CT are accurate and practical indexes evaluating APE severity,and it possesses im- portant significance.

Objective To discuss the effect of QGY/CDDP hepatoma lines multi-drug resistance (MDR) reversed by gene transfection of mdr1,mrp-ASODN+ultrasound contrast agent+ultrasound.Methods The QGY/CDDP cells were transfected by mdr1,mrp ASODN+ultrasound contrast agent+ultrasound irradiation respectively and detected of the various indicators:cell adhesion rate,cell sensitivity to cell drug-resistance,the mRNA expression of mdr1 and mrp gene,the expression of P-gp and MRP protein. Results After mdr1-ASODN transfection,the drug sensitivity and expression of P-gp,MRP protein of QGY/CDDP cells were smaller changes(P＞0.05),and the rate of cells adherent and expression of resistance gene mRNA were obvious changes(P＜0.05).After mrp-ASODN transfection,the cells adherent rate,the drug sensitivity,the expression of resistance gene mRNA and P-gp,MRP protein were obvious changes respectively(P＜0.05),the experiment group(group 2')had bigger effects(P＜0.05).Conclusions mdr1. mrp-ASODN+ultrasound contrast agent+ultrasound irradiation could safely partly reverse MDR of hepatoma cells,which is a potential new approach for gene therapy.

Objective To study the electroacupuncture effects of the single point Zusanli or Sanyinjiao on simple obese rats and to observe the regulation of fat metabolism.M[ethods Before and after the treatment,the body weights and lengths of rats in each group were measured tO calculate the Lee's index;besides,total cholesteriol (TC) and triglycerides (TG) in the rat blood were also determined.Finally,the rats were treated and observed for tWO courses,and SPSS11.5 statistical software was employed to conduct statistical analysis of the experimental data.Results A significant difference was observed about the effects on the height,weight,Lee's index,TC and TG between treatment group and the model group or normal control group (P<0.05 or P<0.01),but no significant difference between treatment group and normal control group (P>0.05).Conclusion Electroacupuncture of Zusanli and Sanyinjiao points has effects on simple-obesity rats,which can make weight loss and decrease Lee's index,TC and TG levels.The underlying mechanism may relate to the improvements of fat metabolism.

OBJECTIVETo research the clinical application of lower cervical pedicle screw fixation procedure.

METHODSFrom September 2011 to July 2013,32 patients underwent posterior pedicle screw-rod system fixation were retrospective analyzed includinig 20 males and 12 females with an average age of 56.4 years old ranging from 21 to 78 years. Among them, 10 patients were traumatic cervical spinal injury, 9 patients were cervical spinal canal tumors, 7 cases were posterior longitudinal ligament ossification of cervical vertebrae, 6 cases were multiple segmental cervical spondylopathy. Preoperatively, X-ray, computed tomography, magnetic resonance imaging and magnetic resonance angiography of the vertebral artery were performed in all patients. After the operation and during the follow-up,X-ray and computed tomography were performed to confirm the pedicle screw position. The accuracy of the pedicle screw placement was evaluated by 4 grades classification from Lee. The spinal cord function was assessed by ASIA impairment scale for traumatic patients and JOA score for non traumatic patients.

RESULTSTotally 144 pedicle screws performed on 32 patients from C3 to C7 involving 132 screws of grade 0,5 screws of grade 1,5 of screws grade 2 and 2 screws of grade 3 according to postoperative CT. There were 12 screws penetrating the pedicle cortex including 8 screws at lateral,2 screws at caudal, 1 screw at medial and 1 screw at cranial. The follow-up time was 12 to 33 months with an average of (21.0±1.5) months. The spinal cord function was not improved in 6 complete cervical spinal cord injury patients,but their paraplegic level descended 1 to 3 segments. Four incomplete cervical spinal cord injury patients' ASIA impairment scale was increased by 1 to 2 grades in average. The JOA score of 22 atraumatic patients increased from preoperative 11.5±0.8 to 15.9±0.6 of postoperative at 6 months (P<0.01). There were no screw loosening,screw pullout and screw-rod breakage.

CONCLUSIONThe lower cervical pedicle screw fixation can provide excellent 3D stability of the vertebral column. The operation risk and Complication could be minimized by adequate preoperative evaluation for appropriate cases and individual pedicle screw placement. It deserved the clinical expansion.

Meridian and collateral theory is the core of acupuncture theory. Simple using the syndrome differentiation system of internal medicine of TCM in clinical practice of acupuncture and moxibustion is difficult to reflect the core of acupuncture theories and characters of clinical acupuncture treatment. The establishment of clinical syndrome differentiation system of acupuncture should base on characters and laws of acupuncture and take the syndrome differentiation according to meridian and collateral theories as main body, syndrome differentiation according to location as key, syndrome differentiation according to eight principles as guidance, syndrome differentiation according to zang-fu theory as complementarity, and pay attention to application of acupoint specificity in clinic, so as to reflect unique character of acupuncture theory and insure the veracity of syndrome differentiation of acupuncture and efficacy of acupuncture treatment.
