Objective To assess whether survival differed among patients who had triple-negative breast cancers compared with patients who had non-triple-negative breast cancers.Methods The clinicopathologic data of 684 patients with operable breast cancer,who were treated with multimodal therapy from December 1998 to June 2007 were analyzed.Of these patients,107 cases were confirmed to have triple-negative tumor histology(triple-negative group),577 cases were confirmed to have non-triple-negative tumor histology(non-triple-negative group).The 7 years cumulative survival and disease-free survival were analyzed by Kaplan-Meier method and compared by Log-rank test.The prognosis Was analyzed by COX regression model.Results The 7 years overall survival rates for triple-negative group and non-triple-negative group were 51.4%(55/107),74.2%(428/577),respectively,there Was significant difference between the two groups(P<0.01).However,the 7 years overall survival rates of patients with triple-negative group and those who with Her-2 positive were 51.4%(55/107)and 53.1%(43/81)respectively,there Was no significant difference between them (P>0.05).Univariate analysis revealed that the factors affecting the disease-free survival included age,menopausal status,tumor size,lymph nodes metastasis,estrogen,progesterone,and Her-2 receptors status.Multivariate analysis showed minor size,lymph nodes metastasis,estrogen,progesterone,and Her-2 receptors status were independent prognostic factors.Conclusions This study has shown a trend towards a poorer outcome for patients with triple-negative breast cancer similarity to patients with Her-2 positive cancers.Triple-negative breast cancer is an independent predictor factor of survival.

ObjectiveTo observe the effect and safety of postoperative patient-controlled epidural analgesia with dezocine plus ropivacaine in patients underwent hysterectomy.Methods60 patients,ASA Ⅰ ~ Ⅱ,undergoing hysterectomy operation.were randomly divided into two groups.0.225% ropivacaine with 0.005% dezocine ( DR group) or 0.225 % ropivacaine with 0.003% morphine (MR group) were given epidurally after surgery,respectively,with an initial loading dose 5m l,basal dose of 2ml/h,PCA dose of 0.5ml and lockout time of 15 min.Visual analogue score(VAS),Bruggemann comfort scale(BCS),Ramsay sedation score(RSS),PCEA effective compression of the times and adverse effects were determined and compared at 1 h,4h,8h,12h,24h 36h and 48h after operation.PCEA effective compression of the number and incidence of adverse reactions were observed.ResultsThere were no significant differences in VAS,BCS,RSS and PCEA effective compression of the times between two groups( all P > 0.05 ).The percentage of nausea,vomiting and pruritus were significantly lower in group DR than that in group MR( all P <0.05).ConclusionPatient-controlled epidural analgesia with dezocine plus ropivacaine in patients underwent hysterectomy had analgesic effect and safety,with less advers eeffects.

ObjectiveTo explore the effect of ultrasonic harmonic scalpel on stress after radical resction of esophageal carcinoma.MethodsAll 115 patients of esophageal carcinoma undergone radical esophagectomy were analyzed retrospectively.60 patients were performed with ultrasonic harmonic scalpel,the other 55 patients were performed with electrotome.The drainage volume of 72h after operation,postoperative complications and hospital days were analyzed.White blood cell count,Neu,CRP and blood glucose level were tested 2 days after operation.ResultsThere was significant difference in the drainage volume of 72h after operation (P < 0.05 ),but the postoperative complications and hospital days had no obvious difference.White blood cell count,Neu,CRP and blood glucose were obviously increased after operation( all P < 0.05 ) ;the barmonic scalpel group was dramatically decreased as compared with the electrotome group except blood glucose ( all P < 0.05 ).ConclusionRadical resection of esophageal carcinoma using ultrasonic harmonic scalpel appears to decrease the drainage volume of 72h after operation and less the stress.

Objective To prepare a novel monoclonal antibody (mAb) that specifically against Mycobacterium tuberculosis culture filtrate protein 10 (CFP-10).Methods The BALB/c mice were immunized by a peptide with 14 amino acids (aa residues 53 to 66) of CFP-10,and then the splenocytes of mice were fused with myeloma cell line SP2/0.The resultant fused cells were subjected to screening culture,enzyme linked immunosorbent assay (ELISA) assay and subcloning by limited dilution to establish hybridoma cell lines of stable secreting anti-the peptide of CFP-10 antibody.The antibody was purified,and its isotypes were analyzed.Then,the antibody was further evaluated by Western blotting,immunoprecipitation and ELISA in 38 culture supernatant samples of Mycobacterium tuberculosis,20 culture supernatant samples of non-Mycobacterium tuberculosis,32 samples of tuberculous pleural effusion,24 samples of non-tuberculous pleural effusion,and 20 serum samples from healthy controls.Results The isotype of the mAb against the specific peptide of CFP-10 was an IgG1 with κ chain,and it was applicable for Western blotting and immunoprecipitation analysis.ELISA quantitative test showed that the sensitivity and specificity for diagnosis of Mycobacterium tuberculosis were 78.6% (55/70) and 92.2% (59/64),respectively.Conclusion The mAb generated against the specific peptide of CFP-10 is high in sensitivity and specificity,and it might be used in the early diagnosis of tuberculosis.

The pharmacokinetics of thyrotropirrreleasing hormone (TRH) made in China was studied in rabbits. TRH concentrations in plasma, urine and various tissues were measured by RIA. After intravenous injection of TRH, the plasma concentration-time curve was shown to fit a two compartment open model with the following pharmacokinetic parameters: 0.8 mg/kg, T1/2?=0.551 min, T1/2? = 9.374 mm, VI = 3.018 ml/kg, Vb = 22.659 ml/kg and AUC = 0.479g. L-1. m-1; 2.0mg/kg, T1/2? = 0.629 mm, T1/2?= 9.734 min, VI = 5.135 ml/kg, Vt = 28.848 ml/kg, and AUC = 0.962g. L-1. m-1; 5.0mg/kg, T1/2? =0.720 min, T1/2?= 10.738 min, VI = 6.120 ml/kg, Vb = 31.928 ml/kg and AUC=2.540 g. L-1. m-1. TRH was distributed widely in tissues and concentrated mainly in the kidney and pituitary. TRH was eliminated partly by the kidney and 21.9% was excreted within 2h after intravenous injection.

Objective To evaluate the consistence in the detection of antibodies against HIV-1 between a new rapid test using oral mucosal transudate (OMT) samples and ELISA using serum samples. Methods Two-hundred patients who were positive for anti-HIV-1 antibodies by serum ELISA and confirmed by Western blot to be infected with HIV, and 600 healthy human controls negative for anti-HIV-1 antibodies by serum ELISA, were eligible for this study. OMT samples were collected from these subjects and subjected to a rapid test for anti-HIV-1 antibodies. The factors influencing the performance of the rapid test were analyzed. Results Of the 200 OMT specimens from HIV-infected patients, 198 showed positive reaction, 2 showed negative reaction. Among the 198 positive reactions, 192 (96%) were "clear" and easy to make decisions, 4 (2%) were "faint", 2(1%) were "very faint" and required professionals to make decisions. The rapid test was negative in all the 600 OMT specimens from the control group. Conclusions The consistence in the detection of anti-HIV-1 antibodies between the OMT rapid test and serum ELISA was 99% in HIV-positive specimens, 100% in HIV-negative specimens, and 99.75% in all the specimens.
