Objective To investigate the anti-fibrogenesis property of imatinib mesylate in a rat model of liver fibrosis induced by carbon tetrachloride/olive oil and its effect on the expression of trans- forming growth factor(TGF)-?1.Methods Rat liver fibrosis was induced by intraperitoneal administra- tion of carbon tetrachloride and olive oil mixture twice a week for eight weeks.Imatinib mesylate was given 20 mg/kg daily by oral lavage.The control rats received saline by oral iavage.Liver collagen depo- sition was evaluated by immunohistochemistry with Masson staining.The activation of hepatic stellate cells was detemined by the immunohistoehemistry staining of?-smooth muscle actin.The mRNA expres- sions of TGF-?1,c-Abl and TIMP-1 were measured by RT-PCR.While protein expressions of TGF-?1, phosphorylated platelet-derived growth factor receptor and c-Abl were detected by Western blot and im- munohistochemical staining.Hepatic hydroxyproline content was also quantified.Results The collagen deposition[(16.23?1.01)%vs(25.61?0.92)%]and the number of activated HSCs(10.52?1.33vs 13.10?1.21)were reduced in the imatinib mesylate treatment group compared with the control group by 35% and 20%,respectively(P

The clinical effect of Traditional Chinese Medicine (TCM) in the treatment of primary bronchial lung cancer is good. To a certain extent, TCM can control the progress of the disease and improve quality of life by the treatment of syndrome differentiation, disease-modified prescription, experience prescription, Chinese patent medicine, TCM injection, acupuncture and acupoint application, which have been combined with chemotherapy. The mechanism of TCM in the treatment of primary bronchial lung cancer mainly includes inhibition of lung cancer cell proliferation, induction of lung cancer cell apoptosis, improvement of body immunity and overcoming chemotherapy resistance.

Objective To investigate the clinical significance of hepatocyte nuclear factor 4α(HNF4α)in rectal cancer and its relationship with prognosis.Methods Real-time PCR was designed to detect the expression of HNF4αon mRNA level and the immunohistochemistry was used to determine the expression of HNF4αon protein level in rectal cancer tissue.The relationship between HNF4αexpression and clinical characteristics was also analysed.The Kaplan-Meier method was used for univariate analysis and a Cox proportional hazards regression model was performed for multivariate analysis.Results HNF4αwas low expressed both on mRNA (t=6.092,P<0.001)and protein level (χ2 =15.230,P<0.001)in rectal cancer tissue.HNF4αexpression on protein level was related with the clinical stage (χ2 =48.311,P<0.001),depth of invasion (χ2 =23.911,P<0.001),histological differentiation (χ2 =20.787,P<0.001),lymph node metastasis (χ2 =39.064,P<0.001)and distant metastasis (χ2 =5.146,P=0.04),while age and gender were not relevant.The cumulative 3-year overall survival of patients with low HNF4αexpression (43.8%)was much worse than the patients with high HNF4αexpression (95 .5%),and the difference was statistically sig-nificant (P<0.001).Univariate analysis revealed that HNF4αexpression (χ2 =28.778,P<0.001),differ-entiation (χ2 =26.680,P<0.001 ),clinical stage (χ2 =32.702,P<0.001 ),depth of invasion (χ2 =6.226,P=0.013),lymph node invasion (χ2 =15.270,P<0.001)and distant metastasis (χ2 =21.817, P<0.001)were statistically significant worse predictors for rectal cancer,whereas age and gender were not rel-evant.The multivariate Cox proportional hazard analysis revealed that HNF4αlow expression (RR=6.084, P=0.028)was independent prognostic markers for 3-year overall survival in the patients with rectal cancer. Conclusion HNF4αwas closely related to the tumorigenesis and progression of rectal cancer,which is an independent prognostic marker for rectal cancer,and which may be an effective target for the therapy of rectal cancer.

Objectives To investigate the effect and mechanism of terbutaline sulfate on pulmonary fluid transport in pre-mature rats. Methods Pregnant rats were randomly divided into 5 groups (control group, premature group, low-dose terbutaline group, high-dose terbutaline group and dexamethasone group). Drugs were administered by gavage after rats were fertilized for 16 days and continued for 3 days. Premature rats were taken out from the 19 days pregnant rats, and mature rats were delivered on the due day. Lungs were collected, and the ratio of pulmonary wet weight to dry weight (W/D), Na+, K+-ATP ase activity and concentration of cyclic adenosine monophosphate (cAMP) were measured in lungs. Results The W/D rate, Na+,K+-ATPase acti-vity and cAMP concentration in lungs had significant difference among different groups (P<0.01). The W/D rate was highest in premature group and lowest in the control group. It was lower in the high-dose terbutaline group than in the low-dose terbutaline group and the dexamethasone group (P<0.05). The Na+,K+-ATPase activity was lowest in premature group and highest in high-dose terbutaline group. It was higher in dexamethasone group, low-dose terbutaline group, and high-dose terbutaline group than in premature group, and it was higher in high-dsoe terbutaline group than in low-dose terbutaline group and dexamethasone group (P<0.05). The cAMP levle was lowest in premature group and highest in high-dose terbutaline group. It was higher in dexamethasone group, low-dose terbutaline group, high-dose terbutaline group than in premature group, and it was higher in high-dose terbutaline group than in low-dose terbutaline group and dexamethasone group (P<0.05). Conclusions Terbutaline sulfate facilitates lung fluid transport in premature rats, leading to reduce the W/D rate in terbutaline-treated group. We speculate that this effect is related to the increased cAMP level and Na+, K+-ATPase activity in lung tissue.
