Aim To study the protective effect of total extract of astragalus(TEA) on primary rat hepatocytes injured by CCl4 or H2O2 and its mechanism.Methods The primary hepatocytes were isolated by Ⅳ collaganase and injured by CCl4 or H2O2.The contents of malondialdehyde(MDA) and glutathion(GSH),glutathion peroxidase(GSHpx) activity of hepatocytes and the AST and /or ALT level in cultural supernatant were determined by general methods. Results (1) The elevation of MDA content of hepatocytes and AST level in supernatant of cultural hepatocytes,and the loss of GSH content and GSHpx activity induced by CCl4 were restored remarkably by TEA(5～80 mg?L-1);(2)The elevation of ALT level in the supernatant of hepatocytes and MDA content of hepatocytes, and the loss of GSH content and GSHpx activity induced by H2O2 were improved significantly by TEA(5～80 mg?L-1) treatment.Conclusion The results suggest that TEA possess direct protective action on primary hepatocyte in vitro injured by CCl4 or H2O2. These might be associated with its anti-oxidative activity.

A total of 135 patients diagnosed with Budd-Chiari syndrome(BCS)during August 2004 and February 2007 were reviewed and analyzed retrospectively.The results showed that 105 subiects (77.8%)caused by malignances,while 29 participants(21.5%)had no definite pathogens.The most commonly seen symptom included jaundiee(69.6%),followed by ascites(48.2%),abdominal distention (40.7%)and lower extremity edema(37.0%).Hisher levels of STB,PT and γ-GT were determined.Color Dopple ultrasound,CT and MRI could be helpful in diagnosing BCS;angiography remained the most accurate measurement.Main treatment strategies were stent implantation and/or balloon dilation.BCS is a clinical syndrome with no typical symptoms.which makes its management very difficult.A complete understanding of the condition will help reduce misdiagnosis.Angiography and stent implantation are primary ways to diagnose or treat BCS.

Objective To observe the spatial and temporal expression patterns of FGFR3 gene and analyze the potential roles of FGFR3 during fracture healing and explore the technique of in situ hybridization of paraffin sections of bone tissue. Methods The fracture model of mouse tibia was established by the standard methods. The expression of FGFR3 mRNA was studied by in situ hybridization during the various stages of bone repair. Results There was faint FGFR3 positive-signal in the cytoplasm of prehypertrophic chondrocytes in soft callus on day 5. FGFR3 mRNA was strongly expressed in prehypertrophic chondrocytes and hypertrophic chondrocytes in soft callus on day 7, but disappeared on day 14, 28 because chondrocytes was replaced by osteoblasts. Conclusion FGFR3 mRNA was strongly expressed in prehypertrophic chondrocytes and hypertrophic chondrocytes in the fracture callus, which shows that FGFR3, a gene that regulates the proliferation of chondrocytes during bone development, may participate in the regulation of differentiation of chondrocytes during fracture healing.

[Objective]To analyse the imaging findings of thoracic and lumbar fibrous dysplasia and evaluate the imaging characteristics.[Method]Among 5 cases of monostotic fibrous dysplasia of thoracic and lumbar spines,4 were imaged with CT scaning,2 with MRI and 5 with X-ray.All materials were analysed.[Result]Each X-ray revealed a round or oval radiolucent lesion surrounded by a distinct and thick rim of sclerosis.CT showed a round or oval low-density lesion with a high-density borderline between the lesion and normal vertebral bone tissue.Bone cortex remained intact in all cases.The lesion showed homogeneous long T1 signal on T1WI and hypo-or isointensity signal on T2WI.There was a characteristic hypointensity loop surrounded the lesion on T1WI,T2WI and PdWI.The lesion was demonstrated obviously in the contrast enhancement of scanning.[Conclusion]Monostotic fibrous dysplasia of thoracic and lumbar spine shows distinctive imaging characteristics that are different from dysplasia of limb bone or skull.These characteristics are decisive in the diagnosis of the lesion.

Objective To explore the effect and significance of AQP4 mRNA expression in bronchial epithelium of chronic obstructive pulmonary disease (COPD) on airway inflammation. Methods Bronchial epithelium was obtained by bronchoscopy in patients with COPD (n=30) and healthy controls (n=30) whose bronchial epithelium was confirmed to be normal by the pathologist. AQP4 mRNA were studied by RT-PCR method. Inflammatory cells infiltration was observed by HE staining; pulmonary function test was performed too before bronchoscopy. Results Compared with that in the healthy controls, AQP4 mRNA expression in COPD was reduced (P

Objective\ To evaluate the immediate effects and strength of allograft fusion cage(AFC) used for reconstructing stability of cervical spine. Methods\ Discs of C 5 and C 6 were resected on 8 fresh human cervical spine specimens, and autogenous iliac bone grafts(AIBG), and AFCs were implanted into the intervertebral spaces respectively. Compression test, pull out test and segmental motion measurement were studied.Results\ Comparing with intact and AIBG groups, the range of motions of C5-6 in AFC group were decreased in all directions except for extension; with (502?114) N compressive load,the vertebrae in AFC group were broken while the AFC were intact, but the AIBG were broken at (135?42) N load; with 300 N drawing load,no loosening was found between AFCs and vertebra, but it was found between AIBG and vertebra at 60 N load. Conclusion\ AFC could provide enough support,anti slide ability and could remain or increase the height of intervertebral spaces. It completely meets clinical and biomechanical requirements.

Purpose:Our experiments are dealing with the affect of docosahexaenic acid(DHA) in doxorubicin to cytoxicity effect of MDA-MB-435s, which is of the anti-human breast cancer and whether it is one of the effect mechanisms that it via the lipid peroxidation of DHA.Methods:Add different match such as anti-cancer drugs?PUFAs?oxidan system of sodium ascorbate and ?-methy-1.4-naphoqui-none?antioxidant of Dl-?-tocopherol and so on to the culture cell line of MDA-MB-435s each 24 hours for 6 days, estimate MDA by TBA with cell extracts and estimate the contents of NO via nitrite salt spectrophotography, then draw out a dosage-effect correlation straight line among contents of MDA,NO and cytoxicity. Mitox is used as contraposition to the peroxidation of ADM which is enhanced by DHA for peroxidation of mitox is low.Results:There have been obvious changes on the contents of MDA of the lipid peroxidation has paralled increased while NO has decreased. There is recitilinear correlation relationship among the contents of MDA and NO from cell extracts and the cytoxicity.Conclusions:It is obvious that DHA can add the cytoxicity of cell line of MDA-MB-435s with ADM, particularly after add non-cytoxicity oxidant. It is lipid peroxidation of oncocyte that one of the mechanisms of DHA can enhance anti-breast cancer effect of ADM.

Objective To find out the main target organs, their main pathological changes and to explore the toxic mechanism of the macleaya cordata. Method SD rats were intoxicated by oral administration with extracts of macleaya cordata followed by pathological and electromicroscopic examination of main organs. Results The LD50 was 19.5% when 1.5g/ml macleaya cordata extract was oral administrated. All pocsoned rat's serum GPT, Cr, BUN, CK, CK-MB increased markedly. The EKG were abnormal. The weight of brain, liver, spleen, and kidneys decreased significantly. There were extensive congestion and hemorrhage in heart, brain, liver and kidneys. The mitochondria, endoplasmic reticulum and nuclear membrane of the rat's heart, brain, liver, and kidney were destroyed. Conclusion The results indicated that the toxic target organs of macleaya cordata were the heart, brain, liver and kidneys mainly. The toxic mechanism of macleaya cordata poisoning was the damage of the mitochondrial, endoplasmic reticulum and nuclear membrane directly causd by the macleaya cordata.

Objective To investigate the role of Survivin gene in the pathogenesis of colorectal adenocarcinoma and its correlation with VEGF in tumor metastasis. Methods The expressions of Survivin mRNA and VEGF protein were detected by RT-PCR and immunohistochemical staining, respectively, in 42 colorectal adenocarcinoma samples. Results Survivin mRNA expression was positive in 23 cancer samples(54 8%), while no expression was detected in adjacent normal tissue. The expression of Survivin gene significantly correlated with histological differentiation and Dukes stage, but not with gender or lymph node metastasis. The expression of VEGF significantly correlated with lymph node metastasis. The expressions of Survivin and VEGF were coincident. The colorectal adenocarcinomas which expressed both the Survivin and VEGF were more inclined to occur lymph node metastasis. Conclusions Survivin gene expression significantly correlated with the clinico-pathologic characteristics and biologic behavior in colorectal adenocarcinoma. Detection of Survivin expression may be valuable for diagnosing colorectal adenocarcinoma, and evaluating malignancy extent and prognosis.
