OBJECTIVE:To observe the short-term efficacy and toxicity reaction of 2 regimens of taxotere combined with epi-rubicin in the neoadjuvant chemotherapy of breast cancer. METHODS:78 patients with locally advanced breast cancer were random-ly divided into TEC group(45 cases)and TE group(33 cases). TEC group was treated with taxotere 75 mg/m2 by intravenous in-jection,d1+epirubicin 60 mg/m2 by intravenous injection,d1+cyclophosphamide 500 mg/m2 by intravenous injection d1. TE group was treated with taxotere 75 mg/m2 by intravenous injection,d1+epirubicin 60 mg/m2 by intravenous injection,d1. 21 days were a treatment course for 2 groups,and there were totally 4-6 courses. In the 2 groups,efficacy and toxicity reaction were evaluated af-ter 4 weeks at least,and survival rate of 6 months was followed-up. RESULTS:The differences were not statistically significant in the short-term efficacy and toxicity reaction and survival rate between 2 groups (P>0.05). CONCLUSIONS:TEC and TC have similar short-term efficacy and safety in the treatment of locally advanced breast cancer. Both of them can be used as adjuvant medi-cines for neoadjuvant chemotherapy.

Objective To explore the present state of clinical decision-making ability of nursing students in Sichuan Province. Methods The instrument for measuring the clinical decision-making ability of nursing students was adopted te investigate baccalaureate nursing students from four colleges and uni-versifies in Sichuan Province who had completed 10-12-month clinical practice. Results The overall mean score of clinical decision-making ability of baccalaureate nursing students in Sichuan Province was (72.86± 4.53). Among the dimensions, the scoring rate of Goal-setting Ability Dimension was the highest and that of evaluation-feedback ability dimension the lowest. In terms of the qualification rate of clinical decision-making ability, 99.52% of the students were qualified (4.82% good and 94.7% passed) and 0.48% was unqualified. Conclusions Baccalaureate nursing students in Sichuan Province have not showed a high level in clinical nursing decision-making ability and most of them are just qualified. No students have reached the level of excellence.

Objective:To clone and express active domain of human granzyme A ( aGzmA ) and detect its biological activity.Methods:Human aGzmA gene was amplified by PCR from the full-length human granzyme A and inserted into prokaryotic ex-pression vector pET24a(+).The constructed recombinant plasmid pET24a-aGzmA was transformed to E.coli BL21(DE3) and induced with IPTG.The expressed product was identified by SDS-PAGE and Western blot.The recombinant protein was purified by the Ni2+affinity column chromatography and the enzyme activity was assayed with BLT substrate.Results: A DNA fragment of 700 bp was amplified by PCR.The recombinant plasmid pET24a-aGzmA identified by enzyme-digesting analysis and sequencing showed that aGzmA gene was inserted into vector plasmid correctly.SDS-PAGE analysis showed that there was a specific protein with a relative molecular mass of about 26 kD.Western blot analysis indicated that the protein could react with mouse anti-His monoclonal antibody specifically.The recombinant protein with high purity could be acquired from the inclusion bodies by the Ni2+ affinity column chromatography and the purified protein had good enzyme activity.Conclusion: The recombinant human granzyme A with good biological activity was prepared successfully.

Objective: To compare the ocular parameters of acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG). Methods: Totally 106 patients with primary angle closure glaucoma were recruited: 58 patients with AACG and 48 with CACG. All patients were divided into 3 groups: AACG attack eyes group, AACG uninvolved fellow eyes group and CACG group and underwent the same ophthalmic examinations, comprising optometry, keratometry, and A-scan ultrasonography. The lens/axial length factor (LAF) and relative lens position (RLP) were calculated. Results: The AACG attack eyes had a significant shallow anterior chamber depth, thick lens, short axial length and larger LAF. hTere tended to be a reduction in the percentage of LAF>0.20 in AACG attack eyes, CACG eyes and AACG uninvolved fellow eyes, though there were no statistically signiifcant difference in all groups (P>0.05). Conclusion: The eyes with AACG attack have a more crowded anterior chamber structure compared with uninvolved fellow eyes and eyes with CACG.

Objective To explore the application value of nasobiliary duct instead of T-tube in primary suture after laparoscopic common bile duct exploration (LCBDE). Methods A total of 58 cases of choledocholithiasis without acutecholangitis were divided into experimental and control group according to the odevity of the last number of admission number .Patients in odd number belonged to experimental group , while the even number patients belonged to control group .The experimental group received endoscopic nasobiliary drainage ( ENBD ) combined with LCBDE and primary suture;the control group underwent LCBDE combined with T-tube drainage .The intraoperative and postoperative data were compared between the two groups . Results All surgeries were completed successfully under laparoscope .The experimental group had much shorter hospital stay than that of the control group [(7.5 ±2.1) d vs.(10.3 ±3.2) d,t=-3.965,P=0.000].No significant differences were found in the operative time , incidence of bile leakage and postoperative incision pain between the two groups (P>0.05).All the cases were followed up for 6-12 months (average, 9 months) and no patients were hospitalized due to complications related to the billiary surgery .MRCP showed no complications such as biliary stricture and residual stones 6 months after operation . Conclusions Nasobiliary duct can substitute for T-tube in LCBDE .It ensures the safety of the primary suture and reduces T-tube related complications .

Background and purpose: Mouse osteosarcoma model was widely used in osteogenic malignant tumor research, and it was helpful for studying the invasion and metastasis of the tumor cells when it was well marked in vivo. The purpose of this study was to establish mouse sarcoma cell lines (S180) that were infected with enhanced green fluorescent protein(EGFP). Methods: EGFP-S180 expressing strong EGFP fluorescence was acquired by electroblot, and supplemented with G418 (800 mg/mL), c-Myc was detected by laser scanning confocal microscopy. Meanwhile, the cancer-bearing model was established subcutaneously within the abdominal cavity. Results: EGFP-S 180 cells were cloned. There was no significantly difference between c-Myc expressions in S180 cells and those in EGFP-S180 cells (P>0.05), and between the cancer-bearing time subcutaneously and the time within abdominal cavity (P>0.05). Conclusion: According to in vitro and in vivo assay, it showed that EGFP-expressing S180 cells could be used for studying further the tumor biological behavior with fluorescence technology.

Objective　To investigate the direct antitumor effect of several surface molecules of Bifidobacterium bifidum 1101 such as whole peptidoglycan (WPG), lipoteichoic acid (LTA), and polysaccharides (PS) on human colonic adenocarcinoma cell line LoVo. Methods　MTT assay and flow cytometry (FCM) were used to evaluate the effect of Bifidobacterial surface molecules on the growth of LoVo cells. Morphological study, fluorescent polarimetry and differentiation-specific enzyme analysis were used to determine whether LTA treatment could induce the differentiation of the cells. Results　LTA but not WPG or PS significantly inhibited the proliferation of LoVo cells in a dose and time dependent manner. Cell cycle analysis by FCM revealed that LTA induced changes in cycle distribution resulting in G0/G1 phase commitment. Morphological alterations observed by light and electron microscopy indicated maturity of cytoplasm and nucleus following treatment by 50μg/ml of LTA. Membrane fluidity was also altered, and intestinal alkaline phosphatase specific for the differentiation of LoVo cells roused dramatically during culture in LTA. It was further found that LTA elevated ［Ca2+］i which resulted from Ca2+ influx instead of the release of stored calcium. Conclusion　These observations indicated that LTA was able to inhibit the growth of LoVo cells and induce the differentiation of the cells. Calcium influx may play an important role in this process.
