Objective To discuss the effects and mechanisms of tetramethylpyrazine(TMP)on learning and memory abilities of Alzheimer's disease(AD)mice.Methods The animal models of AD were induced by aluminium trichloride(AlCl3)intragasticly for forty days.Then,TMP was intragastricly administered for twenty days.The escape latency of the mice in water maze test was recorded;and AChE and SOD activities and MDA levels in the brain were detected by chemical eoiorimetrie method.The expressions of At3 and NF-κB in the cerebral cortex were measured by immunohistochemistry method.Results 1)TMP has markedly decreased escape latency in AlCl3 induced AD mice(P＜0.05).2)In the brain of AlCl3 induced AD mice,TMP reduced AChE activity 19%[(1.37±0.13)U·mgpro-1vs(1.69±0.27)U·mgprot-1,P=0.016],decreased MDA levels 34% [(43.63 4-13.27)nmol·mgprot-1 vs(28.59±8.52)nmol·mgprot-1,P=0.023]and increased SODD activity 39%[(55.81±10.25)U·mgprot-1 vs(40.04±13.06)U·mgprot-1,P=0.026],respectively.These resuits showed significant difference with model mice group(P＜0.05).3)TMP also decreased AB and NF-κB expressions in the cerebral cortex of AD mice models(P＜0.05).Conclusion In AlCl3 induced AD mice,TMP can remarkably enhance the learning and memory abilities,presumably in relation to raise the activity of SOD,reduce the activity of AChE,the levels of MDA and the expressions of AB and NF-κB in the brain.

Qian Hu is the roots of Peucedanum praeruptorum Dunn. The object of the present paper was to determine the effects of water extract (QH-I) and petroleum ether extract (QH-M) of Qian Hu on smooth muscle contractility of isolated rabbit pulmonary artery rings. QH-I and QH-M antagonized pulmonary artery rings conlraction elicited by NE as well as KCl.QH-I and QH-M caused relaxation of rabbit pulmonary artery rings precontracted with NE as well as KCl. The contraction dose-response curves of pulmonary artery rings with NE were shifted to the right and the maximal contraction response were inhibited 73.1 ?8.0% and 43 .6? 4.2% by 1 .6 ? 10-5% and 8.0 ? 10-5%, QH-M, pD'2 = 4.72 ?0.43. These results indicate that Qian Hu may relax pulmonary artery smooth muscle directly as a Ca2+ antagonist

Objective To investigate the protective effect of ω?6 soybean oil fat emulsion on folium sennae?induced diarrhea in mice. Methods Thirty?six Kunming mice were randomly divided into three groups,including control,diarrhea,ω?6 soybean oil fat emulsion group(12 mice in each group). Besides the mice in control group,other mice were administrated folium sennae by gavage for 15 days to establish the diarrhea model. Then mice in ω?6 soybean oil fat emulsion group received ω?6 soybean oil fat emulsion by intravenously administration at a dose of 15 mL/kg daily since 6th day after intragastric administration of folium sennae for 10 days. Animals in control group and diarrhea group were intravenously adminis?tered with same volume of saline. The body weight ,general state and diarrhea index of the mice in each group were dynamically assessed. Ten days after intravenous injection,mice in every group were sacrificed and tissues were collected. Morphology of intestine mucosa was observed after HE staining. Albumin(ALB)level in plasma was evaluated by biochemical method. Proliferating cell nuclear antigen(PCNA)expression in intestine mucosa were assessed by immunohistochemical method. Results Compared with that in the diarrhea group,the general status,body weight and diarrhea index of mice in ω?6 soybean oil fat emulsion group were improved significantly. Ten days after intravenously administration ,pathological change in intestine mucosa of mice in ω?6 soybean oil fat emulsion group was improved significantly ,ALB level in plasma and PCNA expression in intestine mucosa were significantly increased(P<0.05)compared with that in diarrhea group. Conclusion ω?6 soybean oil fat emulsion has a significant protective effect on the diarrhea of mice induced by folium sennae ,which may be related to the up?regulated expression of PCNA by ω?6 soybean oil fat emulsion.

Objective To explore the clinical significance of Ezrin and β?catenin in breast cancer. Methods Immunohistochemical staining method was adopted to detect Ezrin and β?catenin protein expression level in 145 cases of breast cancer tissues,and their correlation with clinical data and prognosis of breast cancer was analyzed. Results Ezrin was expressed in 70 cases(48.3%),β?catenin was expressed in 82 cases (56.6%),and there was significantly negative correlation(r=0.267,P=0.001). The higher histologic grade of breast cancer,the higher expres?sion level of Ezrin(P=0.007),and the lower expression level of β?catenin(P<0.001). Ezrin expression level was increased significantly(P=0.027),but β?catenin expression level was reduced significantly(P=0.011)in lymph node positive breast cancer tissue. Ezrin expression was sig?nificantly correlated with shorter overall survival(P=0.004)and disease free survival(P=0.017)of breast cancer patients,but β?catenin expres?sion was significantly correlated with longer overall survival(P<0.001)and disease free survival(P=0.001)of breast cancer patients. However , Ezrin and β?catenin were not the independent risk factors of breast cancer patients as determined by multivariate Cox regression. Conclusion Ez?rin was significantly negative correlated with β?catenin in breast cancer. They play a role in the progression and poor prognosis of breast cancer , which can be used as breast cancer treatment targets.

Objective: To study the diagnostic characteristics of cardiac amyloidosis (CA) by non-invasive electrocardiography (ECG) in relevant patients. Methods: We retrospectively analyzed 60 CA patients diagnosed in our hospital from 2008-08 to 2013-12 for their clinical and ECG characteristics. Results: There were 48 male and 12 female patients with the ratio of 4: 1. The ifrst time diagnosis rate was low and the average age for conifrmed diagnosis was at (54. 5±14. 2) years.①There were 32 (53. 3%) cases combining heart failure, 12 (20%) with pleural effusion, 20 (33. 3%) with atrial arrhythmia, 8 (13. 3%)with ventricular arrhythmia, 4 (6. 7%)with sino-atrial block, 15 (25%)with atrio-ventricular block, 4 (6. 7%) with left bundle branch block (LBBB), 5 (8. 3%)with RBBB and 8 (13. 3%)with intra-ventricular block.②There were 32 (53. 3%) cases with low voltage on limb leads, 52 (86. 7%) with pseudo-infarct pattern, 48 (60%) with ST-T abnormality and 30 (50%) combining low voltage on limb leads with pseudo-infarct pattern.③The patients combining pleural effusion and with pseudo-infarct pattern had the increased ratio of low voltage on limb leads, while there were still 22 (45. 8%) cases without pleural effusion had low voltage on limb leads.④ ECG characteristics for 60 CA patients were as follows: QRS duration (104±26) ms, QT interval (404±34) ms, QTc (462±35) ms; the R wave of avR 0. 17 mV, QRS wave 0.30 mV; the R wave of limb leads and V1-3 were all<0.5mV, the S wave of V1-3 were 0. 62mV, 1. 61mV, 1. 56mV; the R/S ratio of V1-3 were 0. 19, 0. 12, 0. 20 respectively. Conclusion: CA patients had the highest incidence of pseudo-infarct pattern; meanwhile, combining with low voltage on limb leads, pseudo-infarct with long Q or S wave and ST-T abnormality but normal QRS duration was helpful for differential diagnosis of CA in clinical practice.

Objective:To examine the inhibitory effect and mechanism of niclosamide combined with low-dose cisplatin on adrenocor-tical carcinoma xenografts in nude mice. Methods:A SW-13 cell transplanted tumor model was first established in nude mice. The nude mice were then divided into the control group, niclosamide group, cisplatin group, and combined drug group. The groups were compared in terms of tumor body volume, tumor weight, and biochemical index. The cell apoptosis rate of the transplanted tumor tis-sue was detected by TUNEL assay, while Bcl-2 and caspase-3 protein expression in the transplanted tumor tissue was detected by im-munohistochemistry and Western blot. Results:The terminal tumor volume and weight of the combined drug group were lower than those of the niclosamide and cisplatin groups (all P<0.001). The white blood cell count of the cisplatin and combined drug groups were lower than that of the control group (all P<0.001). Meanwhile, no difference was observed between the cisplatin and combined drug groups (P=0.29). The creatinine and glutamic pyruvic transaminase of the cisplatin and combined drug groups were higher than those of the control group (all P<0.001), whereas no significant difference was observed in the levels of creatinine and alanine aminotransfer-ase between cisplatin and combined drug groups (all P>0.05). TUNEL test results showed that the cell apoptotic rate of the combined drug group was higher than that of the niclosamide group (P=0.004) and cisplatin group (P=0.005). Immunohistochemistry and West-ern blot test results showed that Bcl-2 expression in the combined drug group was lower than those of the niclosamide and cisplatin groups (all P<0.001), while caspase-3 expression in the combined drug group was the highest among those of other groups (all P<0.001). Conclusion:Niclosamide can enhance the inhibitory effect of low-dose cisplatin on the growth of adrenocortical carcinoma and has no additional side effects. This enhancement is probably related to the influence of niclosamide on Bcl-2 and caspase-3 expres-sion levels. Niclosamide promotes the apoptosis of the tumor cells by influencing Bcl-2 and caspase-3 expression.

OBJECTIVE:To compare the differences in the contents of water-soluble total protein,total phenolic acid and total polysaccharides among the water decoctions of crude Cibotium barometz and processed products and to illuminate the effect of pro-cessing on 3 kinds of components of C. barometz.
