Objective To investigate the effects of salvianolic Acid A and B(Sal A,Sal B)on acute myocardial ischemia of rats.Method The rat model with acute myocardial ischemia was established by coronary ligation and intravenous injection of posterior pituitary.The effect of Sal A 10,5,2.5 mg/kg and Sal B 10 mg/kg on the electrocardiogram of different time points,serum creatine kinase(CK),lactate dehydrogenase(LDH)and myocardial infarction area were observed.Results To the rat model was established by coronary ligation,Sal A 10,5,2.5 mg/kg and Sal B 10 mg/kg could lower the ST-segment elevation,reduce infarct size and serum CPK,LDH.The effect of Sal A 10,5 mg/kg was significantly higher than that of Sal B.The role of Sal A 2.5 mg/kg was equivalent to Sal B 10 mg/kg.To the rat model was established by intravenous injection of posterior pituitary,Sal A 10,5,2.5 mg/kg and Sal B 10 mg/kg could lower the ST-segment elevation.The effect of Sal A 10,5 mg/kg was significantly higher than that of Sal B.The role of Sal A 2.5 mg/kg and sal B 10 mg/kg had no significant difference.Conclusion Treatment with Sal A 10,5 mg/kg was more effective in the rat models with acute myocardial ischemia than Sal B 10 mg/kg.Sal A 2.5 mg/kg improved acute myocardial ischemia in rats was equivalent to Sal B 10 mg/kg.

Objective To improve the effects of health education(HE)and satisfaction degree on HE of inpatients by executing hierarchical full-responsibility nursing. Methods Fourteen wards were randomly chosen form the hospital and divided into the control group and the experimental group, each group having 7 wards. The control group carried out routine holistic nursing model, and the experimental group carried out a new hierarchical full-responsibility nursing system. Reforming nursing scheduling and diminishing the nursing unit to assure that the patients acquired the continous and stable nursing service when they were in hospital. The effect and the degree of satisfaction of HE were compared between two groups after 6 months. Results The effects of HE in the experimental group were significantly better than those in the control group, and the degree of satisfaction on HE in the experimental group was much higher than in the control group. Conclusions The hierarchical full-responsibility nursing system can give patients systematic and normalized HE. It can significantly improve the effects and the degree of satisfaction on HE.

BACKGROUND: Currently used poly (alkyl-cyanoacrylates) (PACA) produces aldehyde compound in its degradation, which is easily results in toxicity and stimulation to the body. Here, a novel TaxoI-PACA micell material was synthesized, which has broad application as a kind of liposolubility drug delivery carrier. OBJECTIVE: To verify the therapeutic efficacy of Paclitaxel-PECA micells for mouse breast cancer.METHODS: Paclitaxel drug delivery micells were prepared by a multi-emulsification technique and were characterized for size, drug loading capacity, and in vitro release. Bablc breast cancer model mice were randomly divided into the physiological saline, vacant control, paclitaxel positive control, and Paclitaxel-PECA micells with low-dose, medium-dose, and high-dose groups. Paclitaxel and PaclitaxeI-PECA micells were injected into the location of mouse breast cancer, and then the tumor inhibit rates were detected. RESULTS AND CONCLUSION: The mean diameter of Paclitaxel-PECA micells was 70 nm, with 19.89% loading amount of Paclitaxel. In vitro, micells maintained sustained release of Paclitaxel for 2 weeks. Compared with the physiological saline group, the PaclitaxeI-PECA micells group exhibited superior tumor inhibit effects with doses of 30, 60, and 90 mg/kg (P < 0.001 ), which was 68.49%, 77.03% and 81.87%, respectively. The results suggested that Paclitaxel-PECA micells material has excellent acceptability as sustained-release preparation for treating mouse breast cancer.

Objective:To study interferon alpha (IFN-α) inhibition of proliferation and apoptosis induction of human brain vascular adventitial fibroblasts(HBVAFs)via IFI16.Methods:Cultured HBVAFs were treated with transfection IFI16 siRNA and/or IFN-α in vitro instantaneously.The protein and mRNA levels of IFI16,P53,P21 were measured by Western blot and Real-time PCR.MTT was used to detect the cell proliferation of the HBVAFs.Cell cycle and apoptosis were analyzed by flow cytometry.Results:IFN-α with terminal concentration of 2 000-5 000 kU/L induce significantly expression of IFI16 in HBVAFs,without any significant difference.Stimulated with 2 000 kU/L IFN-α up-regulated the expression of P53,P21 at protein and mRNA levels,and inhibited the cell proliferation and promote cells apoptosis in HBVAFs.Such effect was restrained by transfection with IFI16 siRNA into HBVAFs.Conclusion:IFN-α inhibits HBVAFs proliferation and induces apoptosis may partly relate to the increased IFI16 expression.

Objective To study the efficacy of CPT-11 TACE in the treatment of unresectable HCC.Methods A retrospective review was undertaken on unresectable HCC patients receiving doxorubicin transarterial chemoembolization (59 cases) and irinotecan(CPT-11) in 24 cases from May 2003 to November 2011.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the two groups were assessed for statistical significance with the log-rank test.Results Overall survival time was significantly longer in patients treated with CPT-11 compared with doxorubicin treated group (21.7 vs 14.5 months,P =0.042).There was no significant difference in time to progression between the two groups,but time to progression was longer in CPT-11 group than doxorubicin treated group (11.42 vs 9.46 months,P =0.091).Subgroup analysis showed that for intermediate-stage HCC,CPT-11 resulted in a significantly longer time to progression and overall survival compared with doxorubicin treated group (P =0.029 and P =0.014,respectively).There were no significant differences in adverse events among the two groups (P ＞ 0.05).Conclusions Chemotherapeutic agent CPT-11 in the form of TACE significantly improved overall survival when compared with doxorubicin for the treatment of unresectable HCC.

Objective To evaluate the efficacy of chemoradiotherapy in patients with unresectable pancreatic cancer who were previously treated with PTCD.Methods From September 2005 to December 2012,47 unresectable pancreatic cancer patients with obstructive jaundice were enrolled in this study.They were divided into two groups.21 patients received after PTCD chemotherapy or radiation,or chemoradiotherapy.26 patients in support care group received only nutrition,analgesia and other related support treatment.Survival analysis was performed with Kaplan-Meier statistics.Differences in survival between the groups were assessed for statistical significance with the log-rank test.Results The median overall survival time of patients after PTCD was 7.19 months.The median overall survival time of chemoradiation group was 9.07 months,which was higher than that of support care group (5.52 months),P=0.017.12 patients received single therapy (either chemo or radiation),and 9 patients received chemoradiotherapy.The median overall survival times were 8.31 months and 11.15 months,respectively (P =0.325).Conclusions Post PTCD chemoradiotherapy helps prolong the survival time in unresectable pancreatic cancer patients.

Objective: To study the impact of interferon-inducible protein 16 (IFI16) inhibition on apoptosis of human aortic adventitial fibroblasts (HAAFs). Methods: Our research included 3 groups: ① IFI16-siRNA group, specific small interference RNAs (siRNAs) of IFI16 were transfected into HAAFs in vitro to make IFI16 gene silence, ②Con-siRNA group, non-specific siRNAs were transfected into HAAFs as negative control and ③Untreated HAAFs group, blank control. HAAFs cell cycle and apoptosis rate were examined by flow cytometry, IFI16 mRNA expression was measured by real time qRT-PCR, protein expressions of IFI16, p53, p21, Bax and Bcl-2 were detected by Western blot analysis. Results: Compared with Con-siRNA group and Untreated HAAFs group, IFI16-siRNA group showed decreased apoptosis rate of HAAFs (3.33±0.41) % vs (7.42±1.51) % and (6.49±1.10) %, P<0.05, reduced ratio of G0/G1 phase cells (56.64 ± 4.77 ) % vs (69.67±3.54) % and (68.29±4.14) %, P<0.05, while increased ratio of S phase cells (25.23±5.19)% vs (13.76±2.07) % and (14.04±3.00) %, P<0.05. Meanwhile, IFI16-siRNA group presented down-regulated IFI16 mRNA and protein expressions, decreased protein levels of p53, p21, Bax and increased protein level of Bcl-2, all P<0.05. Conclusion: Inhibited IFI16 expression could decrease HAAFs apoptosis, promote cell cycle transition from G1 to S phase which might be related to the suppression of p53/p21 signaling pathway and regulation of Bax/Bcl-2 expression.
