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.

Objective To evaluate the clinical application and safety of CT-guided transthoracic cutting needle lung biopsy in diagnosing diffuse lung diseases. Methods By using automatic biopsy gun (14 & 16 gauge), CT-guided transthoracic cutting needle lung biopsy was performed in 29 cases with diffuse lung diseases. The samples obtained were sent for pathological and immunohistochemical examination. The sampling successful rate, the diagnostic accuracy and the occurrence of complications were analyzed. Results Technical success rate was 100%, and large size of sample enough for pathological and immunohistochemical examination was obtained in all 29 cases. Definite pathological diagnosis could be made in 25 cases, with the positive diagnostic rate of 82.8%. The main complications included pneumothorax and pulmonary hemorrhage. The symptoms in most cases were not severe and disappeared within one week after the treatment. Conclusion For the diagnosis of diffuse lung diseases, CT-guided transthoracic cutting needle lung biopsy is a safe, easy, effective and reliable method with high successful rate, high diagnostic value and fewer complications, in these respects this technique is superior to transbronchial lung biopsy, open lung biopsy and video-assisted thoracoscopic lung biopsy. Therefore, this technique should be popularized in clinical practice.

Objective To investigate the clinical effect of super selective embolization combined with opera-tion for treatment of meningiomas.Methods 82 cases treated by operation and pathology in return for meningioma were collected in the study,including 44 cases of preoperative superselective embolization for aneurysms as the treat-ment group,and the remaining 38 cases without preoperative embolization of patients as the control group.The opera-tion time,bleeding amount in the operation and the rate of total tumor removal were recorded and compared between the two groups.Results The average amount of bleeding of treatment group was (330.36 ±95.41)mL.The average amount of bleeding of control group was (460.82 ±114.64)mL.The data of the two groups was statistically significant (t =5.624,P <0.01).,The treatment group bleeding amount was less than that of the control group;,the mean oper-ation time of treatment group was (5.36 ±2.62)h,,the average operation time of control group was (6.63 ±2.25)h.The data of the two groups was statistically significant (t =2.355,P =0.021 ),the operation time of the treatment group was less than that of the control group.The total resection rate was 70.4% in treatment group and 36.8% in the control group,there was statistically significant (P <0.05),and the total resection rate in the treatment group was higher than that in the control group.Conclusion Compared with single operation treatment of meningiomas superse-lective embolization combined with operation for treatment of meningiomas can shorten operation time,reduce intraoperative hemorrhage,improve the rate of total tumor removal.It can reduce the operation risk and improve the treatment effect.

Objective To study the role of CT in the evaluation after patellar dislocation triple surgeries.Methods Retrospectively analysed the CT measurements of 60 recurrent patellar dislocation patients (61 knees),who had undergone patellar dislocation triple surgeries,within one month before and after procedures.The measurements included patellar tilt angle,lateral patellar displacement,trochlear con-gruence angle,Tibial Tuberosity-Trochlear Groove distance,Insall-Salvati Ratio and Caton-Deschamps Index.Moreover,the troch-lear dysplasia classifications of all patients were evaluated.In addtion,an analysis has also been completed for 40 (41 knees)of 60 patients who had second postoperative CT examinations as follow-up assessment 3 to 6 months after surgeries.Results All one-month postoperative measurements decreased obviously with statistical significance(P <0.05 ).Furthermore,one case of subluxa-tion,1 1 cases of abnormal Tibial Tuberosity-Trochlear Groove distance,13 cases of abnormal Insall-Salvati Ratio and 14 cases of Ca-ton-Deschamps Index abnormities were also observed.Besides that,it was also found that all patients had trochlear dysplasia and 5 cases were diagnosed with patellar subluxation or dislocation at the second postoperative follow-up assessment.Conclusion The patients with redislocation or risks for patellar instability can be detectecd by CT which provides objective evidence for postoperative evaluation and further treatments.

Objective To investigate the effect of endoplasmic reticulum stress in hyperlipidemia rats with acute pancreatitis(AP).Methods Forty-eight SD rats were divided into AP group(n=18,in- duced by injection of 40?tg/kg caerulein in normal rats twice with 2 hrs interval),normal control(n=6), byperlipidemia group(n=6,fed with a high-fat diet for 8 weeks)and hyperlipidemia AP group(n=18,in- duced by injection of 40?g/kg caerulein in hyperlipidemia rats twice with 2 hrs interval).The rats were sacrificed at 9,12,24 hrs(6 of each),respectively.Serum level of amylase was tested and the pathologi- cal changes of the pancreatic tissues were observed.The index of pancreatic apoptosis was assessed by TUNEL method.The expression of GRP78/Bip(glucose regulated protein)protein was determined by immunochemistry,the endoplasmic reticulum stress related molecules of XBP-1 splicing(X box binding protein),CHOP/GADD153(C/EBP-homologous protein or growth arrest and DNA-damage-inducible gene 153),caspase-12 were analyzed by RT-PCR.The dynamic expressions of GRP78/Bip and caspase- 12 were determine,d by Western blot.Results Artier 8 weeks of fat diet in hyperlipidemia rats,the ser- um levels of triglyceride[(0.99?0.38)mmol/L]and cholesterol[(3.17?0.18)mmol/L] were signifi- cantly increased(P
