Objective To study the efficacy of intra-tumoral injection of different concentrations of ethanol for nude mice with implanted pancreatic cancer and provide evidence for choosing appropriate concentration of ethanol for clinical treatment of pancreatic cancer.Methods A subcutaneous xenograft mouse model of human pancreatic cancer SW1990 was established.Forty-eight nude mice with similar tumor size were randomly divided into 20%,40%,60%,80%,95% ethanol injection groups and saline injection group.The longest (a) and the shortest diameters (b) of tumor of nude mice were measured.Tumor volume (TV),relative tumor volume (RTV) and the relative rate of tumor proliferation (T/C%) were calculated.Eight days later the nude mice were sacrificed.The tumor tissue was harvested for pathologic examinations.Results RTV in 20% ethanol injection group was similar that of saline injection group (P =0.212).RTV in 40%,60%,80% and 95% ethanol injection groups were significantly lower than that in saline injection group (P < 0.01).RTV was less than 1 and T/C% was less than 30% in 60%,80% and 95% ethanol injection groups.The values of RTV and T/C% decreased with the increase of ethanol concentration.RTV in 80% and 95% ethanol injection groups were significantly lower than that of 60% ethanol injection group (P =0.003 and P =0.009).RTV was similar in 80% and 95% ethanol injection groups (P =0.819).The pathologic examinations showed no tumor necrosis in saline injection group,while small amounts of necrosis in implanted pancreatic cancer was observed in 20% and 40% ethanol injection groups,while a large area of coagulation necrosis could be found in 60%,80% and 95% ethanol injection groups.Conclusions Intra-tumoral injection of 80% ethanol is feasible therapy method for nude mice with human pancreatic cancer xenografts.

Objective To observe the effects of electroacupuncture (EA) on c-Jun amino terminal kinase (JNK) signaling pathway and inflammatory cytokines interferon-γ (IFN-γ) in substantia nigra (SN) cells of rotenone-induced rats model of Parkinson's disease (PD),and explore the underlying mechanism of EA on PD.Methods A total of 32 male Sprague-Dawley mice were randomly and evenly divided into a normal group,a shamoperation group,a model group and an EA group.Model group and EA group were injected intradermally with rotenone (1 mg/kg,dissolved in DMSO and saline,concentration:O.25 mg/ml) on the nape of neck.Sham-operation group was injected the same dose of DMSO and saline.Normal group had no intervention.EA group was applied to Fengfu (DU16) and Taichong (LR3) acupoints after the establishment of PD model in rats.Behavioral assessment was conducted after the treatments,the rats were sacrificed for sampling substantia nigra tissue to detect the expressions of tyrosine hydroxylase (TH),p-c-Jun amino terminal kinase (p-c-Jun) and interferon-γ(IFN-γ) protein with Western blotting (WB).Results Model rats showed significant PD syndrome characteristics,comparing with normal group and sham group,the difference was not statistically significant (P > 0.05).The results of open box test showed that the scores of model group rats decreased significantly in terms of the horizontal movement [(19.12 ±2.34) points] and vertical locomotor activity [(5.27 ± 1.04) points] when compared with normal group and sham group,the difference was statistically significant (P < 0.05).After EA treatment,locomotor activity of rats increased significantly when compared with model group (P < 0.05),however,the normal group and sham group was not statistically and significantly different in locomotor activity (P > 0.05).Compared with normal group,the expression of TH protein in (0.183 ± 0.0213) reduced significantly and the expressions of p-c-Jun (0.388 ± 0.0283) and IFN-γ protein(0.453 ± 0.0332) increased significantly in model group,the difference was statistically significant (P <0.05).Compared with normal group,the expression of TH protein(0.324 ± 0.0538) reduced and the expressions of p-c-Jun(0.207 ± 0.0592) and IFN-γ protein (0.239 ± 0.0215) increased in EA group,the difference was not statistically significant (P > 0.05).Compared with model group,the expression of TH protein increased significantly in EA group(P < 0.05),the expressions of p-c-Jun and IFN-γ protein reduced significantly in EA group(P < 0.05).Conclusion EA therapy may reduce the expression of IFN-γ protein in SN of PD rats model by regulating the expression of JNK/mitogen-activated protein kinase (MAPK) pathway,which may delay the process of PD.

Objective Influence of cover statement and clarity of the messages upon risk decision making about thrombolysis therapy in patients with cerebral infarction was discussed in the Scenarios of thrombolytic therapy for acute cerebral infarction.Methods Inpatients and outpatients with cerebral infarction were randomly divided into two groups:detailed / simple cover statement group.Every participant underwent obscure messages and clear messages with only one frame:positive or negative frame.Results In the simple cover statement group,both obscure messages subgroup and clear messages subgroup were not influenced by the framing effect with preference to the risk seeking.In the detailed cover statement group,participants in the clear messages group were not influenced by the framing effect(x 2 =0.19,P>0.05),while the subjects in the obscure messages group were actually affected by the framing effect,with the preference to risk seeking in the positive framework (x 2=7.90,P<0.01).Conclusion The risk decision making about thrombolysis therapy in patients with cerebral infarction is influenced by cover statements and clarity of the messages.To improve the rate of thrombolysis therapy,the patients should be exposed to the obscure messages in the positive framing information under the detailed cover statement.

Objective:To investigate the role of extracellular signal-regulated kinase 1/2(ERK1/2)signal pathway in the pathogenesis of stress-induced gastric ulcer.Methods:Animal model of stress-induced gastric ulcer was established in rats with water-immersion restraint(WIR)stress.The mucosal activation of ERK1/2 was observed before and 5,15 and 30 min,and 1, 2 and 3.5 h after WIR stress.Some animals were also treated with an intravenous injection of PD98059(1 mg/kg),a specific ERK1/2 inhibitor,1 h prior to WIR stress.Expression of total ERK1/2 and caspase-3 were detected by Western blot analysis; ERK1/2 activity was measured by kinase activity assay using myelin basic protein as a specific substrate.DNA-binding activities of the transcription factors activator protein-1(AP-1)and nuclear factor-?B(NF-?B)were determined by electrophoretic mobility shift assays(EMSA).Mucosal TNF-?and IL-1?mRNA expression was analyzed by Northern blot analysis.The degrees of the gastric mucosal lesions were expressed as ulcer index(UI)and pathological evaluation.Apoptosis in the gastric mucosa was examined by an in situ TdT-mediated dUTP nick-end labeling(TUNEL)method.Results:Activated ERK1/2 was very weakly expressed in the gastric mucosa of normal rats.ERK1/2 was rapidly activated in the gastric mucosa of rats 15 min after WIR stress and the activity reached the maximal after 3.5 h.Pretreatment with PD98059 significantly inhibited ERK1/2 activation,decreased AP-1 and NF-?B activities and TNF-?and IL-1?mRNA expression,and obviously relieved gastric mucosal lesions,accompanied by caspase-3 activation and increased apoptosis.Conclusion:The present results indicate that ERK1/2 activation plays an important role in the development of stress-induced gastric ulcer.
