Objective:To investigate the feedback regulation of transforming growth factor ?(TGF-?)to tumor necrosis factor-? converting enzyme.Methods:Reverse transcription polymerase chain reaction(RT-PCR)and immunochemistry were applied to detect TACE mRNA and protein in mice endometria of experiment group(TGF-? antibody was injected)and control group(saline was injected).Results:The expressions of TACE mRNA and protein in control group were higher than in experiment group.Conclusion: TGF-? could feedback on TACE expression in mice endometria and TACE-TGF-?-EGFR might one of the regulations during blastocyst implantation.

Ultrasound,MRI and mammography play significant roles in diagnosis,staging and follow-up of patients with breast cancer.With the development of individualized treatment of breast cancer,the molecular classification of breast cancer has vital reference value for treatment protocols.The requirements of medical imaging evolve from detecting breast cancer by morphological characteristics to making more accurate diagnosis using functional imaging for breast cancer.Correlations between molecular subtypes and ultrasonic,mammographic and MRI features of breast cancer attract broad attention.The correlation of molecular subtypes with uhrasound,MRI and mammography features in breast cancer patients were reviewed in this article.

OBJECTIVETo investigate clinical curative effects of gluteal muscle contracture release combined with insertion of gluteus maximus tendo-chilles lengthening with Z-shaped in treating severe gluteal muscles contracture.

METHODSFrom 2006 May to 2011 May, 20 patients (35 sides) with severe gluteal muscle contracture were collected, including 12 males and 8 females, aged from 8 to 34 years old with an average of 13 years old; the courses of disease ranged from 3 to 21 years. All patients manifested abnormal gait at different degree, knees close together cannot squat,positive syndrome of Ober, positive test of alice leg. Gluteus contracture fascia release were performed firstly in operation, then insertion of tendo-chilles lengthening with Z-shaped were carried out. Preoperative and postoperative gait, and knee flexion hip extensor squat test, cross leg test, adduction and internal rotary activity of hip joint, stretch strength and motor ability after hip abduction were observed and compared.

RESULTSTwenty patients were followed up for 1 to 5 years. Gluteus maximus were released thoroughly, and snapping hip was disappeared, Ober syndrome were negative. There was significant differences in knee flexion hip extensor squat test, adduction and internal rotary activity of hip joint,stretch before and after operation (P<0.01). Gluteus muscle strength was protected,stretch strength and motor ability of hip joint were recovered well. Among them,31 cases got excellent results and 4 good.

CONCLUSIONFor severe gluteal muscles contracture,insertion of gluteus maximus tendo-chilles lengthening with Z-shaped performed after gluteus contracture fascia release could release gluteal muscle contracture to the greatest extent and obtain postoperative curative effect without resection of normal hip muscle fibers and destroy joint capsule.

ObjectiveTo explore the effect of single glucocorticoid treatment and glucocorticoid joint cyclophosphamide treatment on thyroid-associated ophthalmopathy.MethodsRetrospective analysis of clinical data of 35patients used single glucocorticoid( single medicine group) and 16 patients used glucocorticoids joint cyclophosphamide(joint group) was carried out.ResultsThe effective rate of joint group(93.8％ ) was significantly higher than single drug group (68.6％) ( x2 =3.87,P ＜ 0.05).Simple using glucocorticoid had significant treatment effect at CAS score,prominent eyes degrees,soft tissue inflammation score,but the curative effect was significantly lower than the joint group ( P ＜ 0.05 ).The adverse reaction rate had no significant difference between two groups.ConclusionCompared to single glucocorticoid treatment,the glucocorticoid joint cyclophosphamide treatment had better effect and lower adverse reaction rate,especially suitable for patients who had no effect or low effect on hormone therapy.

Objective To explore the preliminary significance of overexpressed MUC-1 mRNA in the pathogenesis of lung adenocarcinoma. Method Total RNAs of 23 paired fresh lung samples and lung adenocarcinoma samples were extracted by routine Trizol way. After total RNAs were transcribed into cDNA, the expression of MUC-1 gene was detected in these samples by real-time PCR. Finally, the correlation of MUC-1 expression with the pathogenesis of lung adenocarcinoma was analyzed. Result Compared with normal lung tissues, the expression of MUC-1 in 20( 87% ) lung adenocarcinoma samples was markedly increased. Compared with early and mid-stage lung adenocarcinoma samples,. the overexpressed MUC-1 in late stage lung adenocarcinoma samples was increased by 2.2 folds. In addition, compared with primary lung adenocarcinoma samples without lymph node metastasis, MUC-1 mRNA was increased in primary lung adenocarcinoma samples with lymph node and distant metastasis ( 2.5 folds). Conclusion Overexpressed MUC-1 may participate in the pathogenesis of lung adenocarcinoma.

AIM:To investigate the effect of tanshinone IIA on the apoptosis of human umbilical vein endothe -lial cells (HUVECs) after high glucose treatment.METHODS:The cell viability was determined by MTT assay.The cell apoptotic rate was examined by flow cytometry with Annexin V-FITC/PI double staining .The expression of Bcl-2 and Bax, and the release of mitochondrial cytochrome C ( Cyt C) were analyzed by Western blotting .RESULTS: Tanshinone IIA significantly inhibited high glucose-induced decrease in cell viability and increased the cell apoptosis .Additionally, after tanshinone IIA treatment , Bax expression and the release of mitochondrial Cyt C were significantly inhibited , while Bcl-2 expression was increased .CONCLUSION: Tanshinone IIA prevents high glucose-induced endothelial cell apoptosis via mitochondria-dependent pathway .

AIM: To construct eukaryotic expression vector of human vascular endothelial growth factor (VEGF) gene, and to explore the effects of VEGF gene on proliferation and chemosensitivity of leukemia cells. METHODS: The recombinant eukaryotic express plasmid pEGFP-C1-hVEGF_(165) was constructed with conventional gene engineering methods. The pEGFP-C1-hVEGF_165 was transfected into leukemia cell K562. The proliferation of the recombinant eukaryotic expression plasmid was analyzed by CCK8 method. The level of VEGF mRNA was detected by reverse transcription and quantitative polymerase chain reaction (RT-PCR). The expression level of VEGF protein was determined by ELISA in cell culture medium and cells. The cell cycle was detected by flow cytometry. RESULTS: VEGF_(165) eukaryotic expression vector was successfully constructed, confirmed by enzyme digestion and sequencing. Compared with the K562 cells transfected pEGFP-C1, the K562 cells transfected with pEGFP-C1-hVEGF_(165) grew faster and expressions of VEGF mRNA and protein increased significantly. In addition, K562 cells transfected with pEGFP-C1-hVEGF_(165) had relatively higher cell survival rate to chemotherapy drugs homoharringtonine(HHT) and fluorouracil(FU). CONCLUSION: VEGF_(165) eukaryotic expression vector increases the level of VEGF mRNA and protein expression, accordingly promotes the proliferation of leukemia cells and decreases the sensitivity of leukemia cells to HHT and FU.
