Background and purpose: Human epidermal growth factor receptor 2 (HER-2) is the member of tyrosine kinase receptor family. Its differential expression plays the key role in choosing targeted drug for breast cancer. This study focused on screening the breast cancer cell clones of different HER-2 expression levels, and studying the bi-ological characteristics of these cells. Methods: Breast cancer SK-BR-3 cells were clonally purified, and the expression level of soluble HER-2 (sHER-2) from the culture supernatant was detected by the ECLIA on ADVIA Centaur CP System. Cell clones with high expression (>50.0 ng/mL), medium expression (15.8-50.0 ng/mL) and low expression (<15.8 ng/mL) of sHER-2 were identified, respectively. This study observed the morphological changes of cell strains with differential expression levels of sHER-2 by cell culture. Besides, biological characteristics were compared by a series of experiments in vitro, such as clone formation, scratch assay, and transwell detection. Results: Compared with normal breast cells, sHER-2 was overexpressed significantly in SK-BR-3 breast cancer cells. Furthermore, the abilities of clone formation, mobility and invasion of sHER-2 high expression cell strain [(51.3±3.4)%, (50.0±0.6)% and (53.5±4.2)%] were signifi-cantly higher than those of sHER-2 medium expression [(42.0±3.7)%, (19.5±3.4)% and (33.2±3.9)%] or sHER-2 low expression [(26.7±2.9)%, (13.6±1.0)% and (28.9±5.4)%], and the differences were all statistically significant (P<0.05). Conclusion: Breast cancer cell strain with high expression level of sHER-2 can enhance cell proliferation, promote cell motility and other biological effects, which may lay the foundation for clinical screening of targeted drug therapies for breast cancer.

Objective To investigate the effects of neurolytic celiac plexus block(NCPB) on stress response during the early stage of partial hepatectomy(PH) postoperation in rats.Methods Thirty healthy SPF-grade male Sprague-Dawley rats were randomly divided into control group and NCPB group,and then were constructed the 70％ PH model.NCPB group received NCPB with 0.5 ％ lidocaine before closing abdominal,and control group received the same procedures,but 0.9％ physiological saline was injected instead of 0.5 ％ lidocaine.The serum concentration of CRP,GC,ACTH,NA and AD,and the levels of serum TNF-α and IL-1β were determined at 6 hours,12 hours and 24 hours after PH.The western blot assay was performed to examine the expression of GR in the peripheral blood mononuclear cells (PBMCs).Results The obvious stress response was produced within 24 hours after PH in rats,postoperative serum CRP,GC,ACTH,NA and AD concentrations increased in the different extent,but the NCPB group were significantly lower than those in the control group in the corresponding time point (P ＜0.01 or P ＜0.05).The expression levels of GR in PBMCs in the control group were significantly decreased after PH,and markedly lower than those in the NCPB group in the corresponding time point(P ＜ 0.01).The serum TNF-o and IL-1β levels were gradually increased in the control group and NCPB group within 24 hours after PH.But at the respective time points,the levels in the NCPB group were significantly lower than those in control group(P ＜ 0.01 or P ＜ 0.05).Conclusion Intraoperation NCPB can effectively inhibit postoperative stress response at the early stage after PH,and thereby help to reduce the degree of systemic inflammatory response.

Objective To analyze clinical pathologic characteristics of patients with primary biliary cirrhosis autoimmune hepatitis overlap syndrome (PBC AIH OS),the incidence of extrahepatic autoimmune disease,malignant tumor and the abdominal lymph node enlargement.Methods From January 2000 to January 2012,the clinical data of 49 patients with PBC AIH OS were retrospectively analyzed,which included general information,clinical manifestations,biochemical parameters,immunological parameters,liver histopathological features,the incidence of extrahepatic autoimmune disease and malignant tumor,imaging findings and the efficacy.Results Among 49 PBC-AIH OS patients,the percentage of patients between 51 and 60 years old was 59.2％ (29/49),and the mean age of onset was (57.2±8.9) years old.Female was 83.7％ (41/49).The percentage of jaundice and pruritus in the main symptoms of initial visit was 42.9％ (21/49).The serum level of alanine aminotransferase (ALT),aspartate transaminase (AST),alkaline phosphatase (ALP),γ-glutamyl transpeptadase (GGT) and total bilirubin (TBil) of 49 patients all increased.Among 31 patients who accepted IgA,IgG and IgM level test,the level of IgM increased in 58.1％ (18/31) of patients,and the level of IgG increased in 61.3％ (19/31) of patients.Ninety-eight percent of patients were antinuclear antibody (ANA) positive,6.1 ％ (3/49) were anti-smooth muscle antibody (SMA) positive,89.8％ (44/49) of patients were anti mitochondrial antibody (AMA) and or AMA-M2 positive.All patients had interface hepatitis.Forty-nine percent (24/49) of patients had both histological features of autoimmune hepatitis (AIH) and primary biliray cirrhosis (PBC).After being treated with ursodeoxycholic acid (UDCA) and immunosuppressant,the percentage of remission,incomplete response and failure was 65.3％ (32/49),26.5％ (13/49) and 8.2％ (4/49),respectively.After remission,five of six patients with medicine withdrawal relapsed.Among 49 patients,40.8％ (20/49) with extrahepatic autoimmune disease and the percentage of Sjogren's syndrome,autoimmune thyroid disease,interstitial pneumonia,systemic lupus erythematosus,psoriasis,sarcoidosis and membranous nephropathy was 16.3％ (8/49),12.2％ (6/49),4.1％ (2/49),2.0％ (1/49),2.0％ (1/49),2.0％ (1/49) and 2.0％ (1/49),respectively.Among 49 patients,14.3％ (7/49) with malignant tumor and the percentage of endometrial cancer,breast cancer,thyroid cancer and lymphoma was 4.1％ (2/49),4.1％ (2/49),4.1％ (2/49) and 2.0％ (1/ 49).Among 49 patients,abdominal ultrasound showed abnormality in 93.9％ (46/49) of patients.Abdominal lymph nodes enlargement was found in 91.8％ (45/49) of patients.Conclusions Autoimmune disease and malignant tumor should be screened when patients with PBC-AIH OS were assessed.Abdominal lymph nodes enlargement found by imaging examination may have guiding significance to the diagnosis.

Objective To examine whether tissue inhibitor of metalloproteinases-1 (TIMP-1) is involved in arterial calcification of chronic renal failure (CRF) rats. Methods CRF model was induced in male Wistar rats by garage daily with 2% adenine 250 mg/kg. The calcification of aorta, femoral artery, renal artery and coronary artery was evaluated histomorphometrically by van Kossa-stained sections at 2-, 4-, 6- and 8-week respectively. RT-PCR and Western blot were used to observe the expressive levels of TIMP-1 mRNA and protein. Expressions of TIMP-1, osteopentin (OPN) and core binding factor α1 (Cbfα-1) protein were analyzed by immunhistochemistry. Results Serum urea nitrogen, creatinine, inorganic phosphate, calcium-phosphorus product and intact parathyroid hormone (iPTH) increased significantly in the model animals compared with control group after 2 weeks (P<0.01). Medial calcification was found in above four arteries of model groups after 6 weeks. RT-PCR and Western blot showed that TIMP-1 expression of model group was significantly higher than that of control group (P< 0.05), and obviously elevated in a time-dependent manner. The expression of TIMP-1 and OPN in calcified aortic smooth muscle cells increased obviously (P<0.05), and positive immunostaining of Cbfα-1 was found. The expression of TIMP-1 was positively correlated with OPN and Cbfα-1 (r=0.317, P=0.000; r=0.485, P=0.000). Conclusions The pathology of arterial calcification in CRF rats induced by adenine is similar to CRF patients, which may serve as a useful model of CRF with arterial calcification. The up-regulation of TIMP-1 seems to participate in the formation and development of vascular calcification in CRF.
