CONCLUSION: The HPLC fingerprint spectrum of Radix Arnebiae can be used as an identification.It may provide the basis for quality control of Radix Arnebiae.

Objective To evaluate effects of human papilloma virus(HPV)16E7 on expressions of six tumor suppressor genes(including MT1G, NMES1, RRAD, SFRP1, SPARC and TFPI2)in a cell line SiHa, as well as on its proliferation and apoptosis. Methods SiHa cells were divided into two groups to be transfected with a small interfering RNA targeting HPV16E7(E7SiRNA, experimental group)and an empty vehicle(negative control group) respectively, with SiHa cells receiving no treatment serving as the blank control group. After 48 hours, qPCR was performed to measure the mRNA expressions of E7 and six tumor suppressor genes, CCK?8 assay to evaluate cellular proliferative activity, and flow cytometry to assess apoptosis of SiHa cells. Results At 48 hours after the transfection, the experimental group showed significantly decreased E7 mRNA expression(0.25 ± 0.036, P<0.05), but increased mRNA expressions of the six genes(MT1G 1.403 ± 0.190, NMES1 1.720 ± 0.060, RRAD 1.390 ± 0.160, SFRP1 1.493 ± 0.120, SPARC 2.157 ± 0.144, TFPI2 2.060 ± 0.122, all P < 0.05). The proliferative activity of SiHa cells was significantly decreased(0.554 ± 0.130 vs. 1.028 ± 0.236 and 1.220 ± 0.126, both P<0.05), but the apoptosis rate was significantly increased(9.222%vs. 0.246%and 0.123%, both P<0.05)in the experimental group compared with the negative control group and blank control group. No significant differences were observed between the negative control group and blank control group in proliferative activity or apoptosis rate of SiHa cells(both P>0.05). Conclusion E7 may participate in HPV16?induced cellular malignant transformation by suppressing the mRNA expressions of 6 tumor suppressor genes, including MT1G, NMES1, RRAD, SFRP1, SPAR and TFPI2.

Objective To evaluate the effect of non-linear blending function for dual-energy CT on image of pulmonary angiogra-phy.Methods 27 patients underwent dual energy CT pulmonary angiography(CTPA).Data obtained with 100 kVp,140kVp,and non-linear blending were divided into group A,B,and C respectively.CT value of emboli were measured.Corresponding signal to noise ratio(SNR )and contrast to noise ratio(CNR)were calculated.One-way Anova analysis and Friedman test were used to ana-lyze statistical significance among these values.Results On quantitative analysis of 27 patients,there was no statistical difference for CT value of CTPA among the three groups(P >0.05).For the noise,CNR and SNR,there were statistically significant among the three groups(P <0.05).Conclusion The non-linear blending function has certain advantages in improved image signal-to-noise ratio and it can be used in CT pulmonary angiography examination for patients suspected pulmonary embolism clinically .

Objective: To study the correlation between intestinal mucosa injuries and inflammatory reaction in cancer cachexia mice. Methods: 14 male BALB/c mice were randomized into two groups: control group and tumor-bearing group.For tumor-bearing group,a suspension of 10 6 murine colon 26 adenocarcinoma cells was inoculated s.c into each mouse.Non-tumor body weight,intestinal villus height,width,basal layer thickness and muscular layer thickness,TNF-?,IL-1,IL-6,IL-10,IFN-?,sTNF-RⅠand sTNF-RⅡ in the serum and intestinal tissue were determined at the 16th day following the inoculation. Results: The non-tumor body weight and intestinal villus height and basal layer width in tumor-bearing group were lost significantly as compared with control group.The concentration of serum TNF-?,IL-6,sTNF-RⅠwere higher and the level of serum IL-10 was less in tumor-bearing group.The concentration of intestinal tissue TNF-? was higher but the IL-1,IFN-?,sTNF-RⅠ and sTNF-RⅡ were less in the tumor-bearing group. Conclusion: The intestinal mucosa injuries have close relation with the inflammatory reactions in cancer cachexia.

Objective To evaluate the relationship between serum matrix metalloproteinase-9(MMP-9), white blood cell(WBC)count and type 2 diabetes mellitus with macroangiopathy and to investigate the mechanism of the protective effects of rusiglitazone(RSG)on blood vessel.Methods Serum MMP-9 was determined by ELISA in 30 normal controls and 80 type 2 diabetic patients(including 40 cases with macroangiopathy and 40 without maeroangiopathy).WBC count and other clinical parameters were also determined.32 type 2 diabetic patients received RSG(4rag qd)for 12 weeks.All parameters were determined after 4 weeks(17 patients)and after 12 weeks(all patients)to observe the changes in MMP-9,WBC and other parameters.Results In the diabetic patients,serum MMP-9 and WBC were markedly higher as compared with normal controls;and MMP-9 and WBC in patients with macroangiopathy[579(440-949)?g/L,(7.51?1.47)?10~9/L]were higher than those [324(275-423)?g/L,(6.22?0.79)?10~9/L]in the cases without macroangiopathy(P

AIM: To explore the expression of caspase -3 (cysteinyl aspartate-specific proteinase) in the neonatal rat cerebral cortex a nd hippocampal after hypoxia-ischemia. METHODS: Sham and hypoxia-ischemia (HI) groups were set up. The neonatal HI procedure was performed in 7-day-old rat pups. The double-lateral co rtex and hippocampal was subjected to pathological assessment, immunohistochemic al staining with caspase-3 antibody and half-quantitative reverse transcription and polymerization chain reaction (RT-PCR) to measure the change in caspase-3 pr otein and mRNA expression. RESULTS: Caspase-3 mRNA in ipsilateral cerebral cortex and hippo campal increased immediately after HI followed by a partial recovery. Thereafter caspase-3 mRNA and protein simultaneously increased with a maximum reached at 2 4-48 h after HI. CONCLUSION: Caspase-3 may play a key role in the development of apoptotic hypoxic-ischemic brain damage (HIBD) in immature rats. Neuroprotective medicine should be used before 24-48 h after HI.

OBJECTIVE:To study the anti-tumor effects of Vinblastine (VLB) hydrophilic group modified cationic liposomes in tumor-bearing mice. METHODS:Tumor-bearing model were induced by inoculating yellow ascites of S180 ascites tumor mice. Tumor-bearing mice were randomly divided into model group,VLB sulfate injection group,VLB liposomes group,VLB hydrophil-ic group modified liposomes group,VLB cationic liposomes group and VLB hydrophilic group modified cationic liposomes group, i.e. group A,B,C,D,E and F,with 18 mice in each group. Group A was given normal saline intravenously via mice tail,other groups were given VLB 1.5 mg/kg every 2 days for consecutive 5 times. The anti-tumor effects of different VLB preparations were compared,using living conditions,survival time,tumor volume and weight,and tissue pathological section as indexes. RE-SULTS:Compared with group A,B,C,D and E,the mice of group F were more active,and had longer survival time,smaller tumor volume and lighter tumor weight,with statistical significance(P<0.05). The tissue pathological section of mice in group F indicated that coagulation necrosis,disintegration,and dissolution of tumor cell nucleus. CONCLUSIONS:VLB hydrophilic group modified cationic liposomes have obvious anti-tumor effect,which are better than other VLB preparations.

Objective To investigate the relationship between serum homocysteine (HCY)levels and oxidative stress in pa-tients with coronary heart disease (CHD).Methods According to the diagnostic criteria of CHD in 2010 (WS 319-2010)is-sued by the Ministry of Health,79 patients with CHD in Xi’an Central Hospital from June 2014 to December 2014 were se-lected as the experimental group,and 5 5 cases of healthy physical examination for the same period were selected as the nor-mal control group.The levels of oxidative stress marker malondialdehyde (MDA)and the activity of antioxidant enzyme su-peroxide dismutase (SOD)in serum were detected to analyze the state of oxidative stress.The levels of serum HCY were de-tected,and the correlation between HCY levels and MDA levels and SOD activity was analyzed.Results The levels of MDA in the CHD group were significantly higher than that in the control group,while SOD activity was significantly lower than that in the control group,the differences were statistically significant (t=3.112,2.684,all P<0.05).The levels of HCY in the CHD group were significantly higher than that in the control group,the difference was statistically significant (t=3.268,P<0.05).In the CHD group,the levels of HCY were positively correlated with the levels of MDA (r=0.236,P<0.05),and negatively correlated with SOD activity (r=-0.221,P<0.05).Conclusion Serum HCY levels were increased and oxidative stress reaction was enhanced in patients with CHD.Oxidative stress was associated with elevated serum HCY levels.Serum HCY levels and oxidative stress played an important role in the occurrence and development of CHD.
