Objective To compare the clinical efficacy of breast-conserving surgery and modified radical mastectomy for early breast cancer and their influence on quality of life.Methods 78 patients with early stage breast cancer were divided into two groups by random number table,and 39 cases in each group.The control group was given modified radical mastectomy,while the observation group was given breast-conserving surgery.The clinical efficacy,surgical conditions and quality of life scores were compared between the two groups.Results The operative time,blood loss,incision length and the average hospital stay of the observation group were (60.23 ± 5.21)min,(44.73 ± 4.22) mL,(4.72 ± 1.02) cm and (9.52 ± 0.86) d,which were significantly lower than those of the control group(t =7.88,8.32,8.89,6.42,all P ＜ 0.05).The postoperative physical factors,mental factors,psychological factors and social factors scores of the observation group were (67.44 ± 3.87),(48.64 ± 3.73),(117.34 ± 8.33)and (61.56 ± 5.32),which were significantly higher than those of the control group (t =5.43,5.87,6.29,7.11,all P ＜ 0.05).The postoperative 3-year local recurrence,distant metastasis and survival rate showed no significant differences between the two groups (x2 =1.22,1.09,1.29,all P ＞ 0.05).Conclusion Breast-conserving surgery in the treatment of early breast cancer has significant effect,and it has less trauma,less bleeding and cosmetic results,and it can be used as the preferred method for the treatment of early breast cancer,which is worth to be further applied in clinical.

OBJECTIVE:To study the active fraction of the seeds of Hovenia Dulcis Thunb.to treat acute alcoholism.METHODES:The seeds of Hovenia Dulcis Thunb.were divided into five parts:superitical fluid extraction(SFE)part,chloroform extraction part,ethyl acetate extraction part,n-butanol extraction part and water extraction part.The effects of the active fraction of the seeds of Hovenia Dulcis Thunb.on ebriety latency,ebriety rate,mortality,and ethanol concentration-time curve of the alcoholism mice were investigated.RESULTS:The ethyl acetate extract could prolong the ebriety latency of the mice,decrease ebriety rate and mortality of the alcoholism mice,and significantly decrease serum ethanol concentrations at 0.5,1,and 1.5h after alcohol administration(P

Objective To insert VEGF-R3(FIT-4)gene fragment into cloning vector and identify it.Methods By T-A cloning,the VEGF-R3 gene fragment amplified by RT-PCR was cloned on the PGEM-T Easy plasmid vector and transfected into E.coli JM109.the recombinant clones were screened by"white-blue plaque selection" and tested by the methods of single restrictional enzyme.Results The VEGF-R3 gene fragment amplified by RT-PCR showed a smear after the electrophoresis on agarose Gel and obtained white clones by"white-blue plaque selection".The electrophoresis result of the recombinant clones tested by the single restrictional enzyme was accordant with expectant result.Conclusion The recombinant clones through the methods T-A may be used in the further gene expression and gene therapy studies.

Objective To investigate induction of apoptosis of human ovarian cancer CoC1 cells by 5-allyl-7-gen-difluoromethylenechrysin(ADFMChR)in vitro,and its molecular mechanism. Methods The proliferative and growth inhibition of CoC1 cells treated with ADFMChR was respectively measured using(3,4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide(MTT)colorimetric assay and clone-formation in soft agar assay. The apoptosis of CoC1 cells induced by ADFMChR was determined by DNA agarose gel electrophoresis assay. Effect of ADFMChR on PPAR-γ, Bcl-2. Bax protein expression level of CoC1 cells was detected by western blotting. Results The proliferation of CoC1 cells could be significantly inhibited by ADFMChR in a dose-dependent manner. The IC50 was 7. 76 μmol/L The ladder-shaped band could be shown in DNA agarose gel electrophoresis after treatment with ADFMChR at 30. 0 μmol/L for 48 h and the ladder-shape band disappeared with GW9662. Western blot analysis showed that expression of PPAR-γ and Bax proteins were up-regulated and protein levels of Bcl-2 were depressed after treatment with ADFMChR in a concentration-dependent fashion. However,the effects of ADFMChR on Bcl-2 and Bax proteins were blocked or diminished in the presence of GW9662. Conclusions The effect of ADFMChR on induction of apoptosis in CoC1 cells may be mediated by activation of PPAR-γ, sequentially accompanied by reducing of protein levels of Bcl-2 and increasing of Bax expression.

MicroRNA (miRNA) controls the proliferation of breast cancer cells in many ways such as cell apotosis,cell cycle and methyltransferase.Also,it controls the metastasis of breast cancer cells in many ways such as microenvironment,epithelial-mesenchymal transition and vessel formation.Large amounts of recent studies indicate that miRNAs are specifically expressed in breast cancer tissue and play important roles in proliferation,metastasis and treatment of breast cancer.

Objective: To observe the effectiveness of neltimicin sulfate in treating the infections of lower respiratory tract.　Methods: 41 cases of lower respiratory tract infections served as observation subjects (treated with netilmicin sulfate 200 mg*d-1, iv drip) while the other 30 cases as control subjects (treated with penicillin 8×109 U*d-1 and ampicillin 8.0 g*d-1, iv drip).　Results: The therapeutic effectiveness was significantly higher in the observation group than that in the control group (P＜0.01). The sensitivity tests of isolates from the sputum showed that 71.1% of the isolates were highly sensitive to netilmicin sulfate, 28.9% moderately sensitive to netilmicin sulfate. The total effectiveness rate was 97.6%.　Conclusion: Netilmicin sulfate is effective in treating the lower respiratory tract infections and causes less side effects.

Objective To analyze the clinical feature and its risk factors on 112 episodes of urinary tract infection (UTI) in patients with lupus nephritis. Methods 112 episodes of UTI in patients with lupus nephritis in our department during the past 5 years were reviewed retrospectively. Epidemiological data and information on urinary symptoms, disease activity (SLEDAI) , leukocyte and platelet data were collected. Autoantibodies, complement levels, urine culture, and antibiogram were determined. Urological studies were carried out. The use of corticosteroids and (or) immunodepressive were also investigated. Results The prevalence of UTI in lupus nephritis patients was 36.5% , and complexity infection(58%) was the main UTI . Symptomatic UTI was 62% , and symptomless UTI was 38% . The mean SLEDAI score was 15.7(SD3.05) , which influenced the onset of UTI (P1/100 IU/ml, leucopenia and thrombocytopenia (P

ⅡB. Our investigation also showed that the activity of PAS, LDH and PFK was stronger in type Ⅱ fibers than in type Ⅰ. It was concluded that each type fibers in the rat plantaris exhibit significant differences in metabolic and functional activity. The type ⅡA fibers present both high activity of glycolytie enzyme and oxidase, and reflect that these enzymes may play very important role in energy metabolism. Further study remains to bedertaken.
