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 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: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.

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.

Objective To investigate the influence of synangio-excision-restruction in pancreatic cancer radical operation on the complications,living quality and survival status in the patients with pancreatic cancer.Methods A total of 255 patients with pancreatic cancer in our hospitals from January 2010 to October 2015 were selected and divided into 3 groups according to different operation modes:41 cases in the Synangio-excision-restruction group(A),113 cases in the non-synangio-excision-restruction group (B) and 101 cases in the palliative by-pass operation group(C).The clinical data in 3 groups were analyzed.The influence of Synangio-excision-restruction on operative complications,living quality and survival status was investigated.Results The incidence rate of complications in the group A was 56.10％,which was obviously higer than 34.51％ in the group 1β and 20.79％ in the group C,and the difference was statistically significant(P＜0.05).In the group A,the incidence rates of belly ache and body weight gain were 36.59％ and 51.22％ respectively,which comparing with 91.09％ and 9.09％ in the group C showed statistically significant difference(P＜0.05).The median survival time(MST) in the group A was 11.83 months,which in the group B and C were 15.43 months and 7.50 months,the difference between the group A and C was statistically significant(x2 =4.27,P＜0.05);while the difference between the group A and B was not statistically significant(x2=3.67,P＞0.05).Conclusion For the pancreatic cancer patients with affected portal vein and inferior mesenteric vein,the synangio-excision-restruction radical operation can obviously prolong the patients' survival time and improves their living quality.

OBJECTIVE: To explore the influence of sublingual immunotherapy on Th2 type immunoreaction in patients with allergic rhinitis within 12 months' treatment. METHOD: Forty three patients with allergic rhinitis were followed-up within 12 months after receiving sublingual immunotherapy. The changes of clinic symptoms and immunoreaction were analyzed. VAS score was applied to evaluate the efficacy of clinic treatment. TIgE and sIgE in serum were tested to evaluate the systemic immunoreaction. Eosinophil counting in nasal discharge was applied to evaluate the local nasal mucosa immunoreaction. RESULT: VAS scores were decreased significantly one month after the starting point of treatment, companied by the decrease of EOS count in nasal discharge (P < 0.05). The changes of TIgE and sIgE in serum within 12 months of sublingual immunotherapy were not significant (P < 0.05). The levels of IL-4 and IL-13 in nasal lavage were decreased significantly after 12 months' treatment. CONCLUSION The bias of Th2 type immunoreaction existed in nasal mucosa immune system in patients with allergic rhinitis could been rectified partially after receiving sublingual immunotherapy for 12 months, but the significant changes were not observed in systemic immune system.

Objective To observe the changes of A20 in mesangial cells of diabetic nephropathy (DN) rat model in?duced by lipopolysaccharide (LPS)-rat, and to explore its possible mechanism. Methods (1)Thirty health male Wistar rats were randomly divided into two group. Model rats were given streptozotocin (STZ) at a dose of 60 mg/kg by intraperitoneal in?jection. Rats in the control group received the same volume of citrate buffer in the same way. Levels of blood glucose and uri?nary microalbumin were detected in two groups at the 6th and the 8th week. Changes of renal pathology were observed by HE staining. Changes of protein A20 were observed by immunohistochemistry. (2) Expression changes of gene and proteins A20, nuclear factor (NF)-κB, IκB, IKKγand MCP-1 in renal cells treated with LPS were determined after treatment with different time points (0, 2, 4, 6, 12, 24, 48 and 72 h) and different concentrations (0.1, 1 and 10μg/L). Results (1) Levels of blood glucose and urinary microalbumin were significantly increased in model group compared with those of control group ( P <0.01). HE stainig showed that hyaline degeneration in tubular epithelial cells was found in model group, especially at the 8th week. Results of immunohistochemistry showed that expression of protein A20 significantly decreased in kidney tubules and nearly disappeared in glomerulus in model group compared with that of control group, which expressed less at the 8th week. (2) There was no significant difference in the expression of IKKγbetween different concentrations and different times. Com?pared with 0 h, the expression of A20 protein was increased at 2 h and 4 h, except that the expression of A20 protein in?creased after 6 h (P<0.05). Meanwhile NF-κB expression increased and IκB expression decreased in different time points (P<0.05). In addition, the expressions of A20 and IκB were decreased concentration-dependently (P<0.05). The expres?sion levels of NF-κB and MCP-1 were increased concentration-dependently (P<0.05). Conclusion A20 may involve in the development of diabetic nephropathy by regulating the NF-κB pathway.

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.
