Objective To explore the relationship of chemotherapy sensitivity and expression of multidrug resistance genes and apoptosis regulation genes in human breast cancer cell lines.Methods MTT assay was used to detect the sensitivity to adriamycin(ADM),cisplatinum(DDP),mitomycin C(MMC),fluorouracilum(5-Fu),carmustine(BCNU) in five breast cancer cell lines including Bcap37,MCF-7,T47D,MDA-MB-231and MDA-MB-435.Multidrug resistance genes including P-glycoprotein(P-GP),Glutsthione-s-transferases-?(GST-?),Lung resistance protein(LRP),multidrug resistance related protein(MRP),MGMT and apoptosis regulation genes FAS,BCL-2,P53 and P16 were examined by flow cytometry(FCM).Results The chemotherapy sensitivity was obviously divergent in different breast cancer cell lines.The correlation analysis showed that there were positive correlations between the sensitivity to 5-Fu in breast cancer cell lines and the expression of P16.There was no correlation among the sensitivity to other drugs and expression of other genes.Conclusions The sensitivity to 5-Fu is related to the expression of P16 in breast cancer cell lines.

Objective To explore the association between clusterin(CLU) gene rs11136000 poly-morphism and late-onset Alzheimer's disease ( LOAD) in Bai population from Dali Bai Autonomous Prefec-ture of Yunnan Province.Methods A case-control study including 109 LOAD patients and 120 normal con-trols matched for age,sex and level of education was taken in Dali Bai population.Polymerase chain reaction (PCR) and single nucleotide polymorphism (SNP) site testing were used to detect genotype and allele fre-quency of CLU SNP rs11136000.SPSS 17.0 was applied to analyze the data.Result ①The different fre-quency ( C:65.60%,T:34.40%,CC:38.53%,CT:54.13%,TT:7.34%) of CLU SNP rs11136000 genotypes and alleles distribution in Bai between LOAD patients and healthy controls showed no statistical significance (χ2=1.529, P=0.216;χ2=2.805, P=0.246) .②The serum total cholesterol ( TC) of LOAD patients was significantly higher than that in that of control group( t=2.508, P=0.013) .Conclusion The results suggest that CLU rs11136000 polymorphism may not be the susceptible gene of LOAD,and high serum total choles-terol is more common in LOAD patients.

Objective To investigate the impact of preoperative portal vein thrombosis (PPVT) on living donor liver transplantation (LDLT).Methods In this study,99 patients who underwent LDLT by the same surgical team of Tianjin First Centre Hospital from 2007 to 2011 were retrospectively analyzed.According to whether there was a PPVT,all the patients were divided into PPVT group (26 cases) and non-PPVT group (73 cases).The preoperative risk factors and the impact of PPVT on LDLT and outcomes were analyzed.Results Among 26 PPVT patients there were 23 cases in grade Ⅰ and 3 cases in grade Ⅱ.Splenectomy was found to be an independent risk factor for PPVT (x2 =10.211,P =0.001).PPVT prolonged the anhepatic phase (Z =-2.430,P =0.015),but the incidence of surical complications and mortality were no statistical differences between the PVT group and the non-PVT groups.Meanwhile,there was no statistical difference of 1-and 3-year survival rate between the two groups(x2 =0.505,P =0.477).Conclusions With proper intraoperative treatment and postoperative prevention,PPVT does not affect the outcomes of patients suffering from grade Ⅰ or Ⅱ PPVT.However,PPVT added to difficulties of operation,so the detailed preoperative evaluation and careful intraoperative operation is necessary.

Objective To evaluate the clinical anesthetic efficacy of a combination of propofol and remifentanil for ultrasound-guided transvaginal oocyte retrieval.Pharmacodynamic (PD) model was established and its characteristics were analyzed based on the simulated concentrations of propofol and remifentanil in respective pharmacokinetic models, so as to guide further study.Methods Forty-two female patients undergoing transvaginal oocyte retrieval were divided into groups PR15 (n=24) and PR10 (n=18), who were received intravenous bolus of remifentanil 1.5 μg/kg + propofol 1.5 mg/kg and remifentanil 1.0 μg/kg+propofol 1.0 mg/kg, respectively.The anesthesia quality evaluation was based on the following indicators: onset time (loss of eyelash reflex), recovery time of orientation, the incidence of hypoxemia (SpO2 < 92%) and adverse reactions.Nonlinear mixed-effects model was used to evaluate the time courses of the simulated propofol and remifentanil concentrations-effect and to establish the PD model with NONMEM software.Results The time of recovering orientation in the patients of group PR10 was significantly faster compared with the patients in group PR15;the time of loss of eyelash reflex , incidence of hypoxemia (12.5% vs 16.7%) and cough (16.7% vs 11.1%) had no significant differences between the both groups.With the final PD model, the estimated parameters as following: EC50 of propofol and remifentanil for effective sedation and analgesia were 1.71 μg/ml and 2.57 ng/ml, respectively.EC95 of propofol and remifentanil for effective sedation and analgesia were 4.30 g/ml and 4.57 ng/ml, respectively.The effect site concentration of propofol 1 mg/kg was lower than EC50, but the effect site concentration of 1.5 mg/kg was higher than EC50.The peak effect site of 1.0 μg/kg and 1.5 μg/kg remifentanil was higher than EC50, and 1.5 μg/kg concentration was close to EC95.Conclusion Based on patients' recovery time, propofol 1.0 mg/kg combined with fentanyl 1.0 μg/kg is appropriate in patients undergoing transvaginal oocyte retrieval.

Objective:To evaluate the clinical efficacy of tendon-regulating manipulation plus kinesiotherapy in treating low back pain. Methods:Sixty patients were randomized into a treatment group and a control group by using the random number table, 30 cases in each group. The treatment group was intervened by tendon-regulating manipulation plus kinesiotherapy, while the control group was by the tendon-regulating manipulation alone. The lumbar lordosis was measured by X-ray (side view), the pain was evaluated by analgesy meter, the lumbar range of motion was by using goniometer, and the function was judged by Oswestry disability index (ODI) before and after treatment, and the therapeutic efficacy was also observed. Results:After treatment, the pain level was significantly reduced, lumbar lordosis was significantly increased, the lumbar range of motion was markedly improved, and the ODI score significantly dropped (allP<0.05) in both groups; the improvement of each item in the treatment group was more significant than that in the control group (allP<0.05). The total effective rate was 90.0% in the treatment group versus 63.3% in the control group, and the difference was statistically significant (P<0.05). Conclusion:In the treatment of low back pain, tendon-regulating manipulation plus kinesiotherapy can mitigate topical pain, improve the motion of low back, enhance the quality of life, and produce a more significant therapeutic efficacy compared to tendon-regulating manipulation alone.

Objective: To investigate the expression of HSP-27,-60 and -90 in gastric cancer and its clinical significance. Methods:66 cases of gastric carcinoma was detected by immunohistochemistry HSP-27,60 and 90 of the expression and clinical significance of combined with clinical and pathological characteristics, tumor cell proliferation and survival analysis of three kinds of heat shock protein expression. Results: HSP-27,-60 and -90 were highly expressed in gastric cancer tissues. HSP-27 expression and tumor size (pT,P=0. 026),organ metastasis (pM,P=0. 046) and pathological staging (P=0. 041),HSP-27 staining intensity and lymph node status were significantly correlated ( pN, P=0. 042 ) . HSP-60 expression was associated with gender ( P=0. 011),and HSP-60 staining intensity was associated with age (P=0. 027) and tumor grade (P=0. 031). There was no correlation between HSP-90 expression and the clinical pathological parameters of this study; however, the intensity of HSP-90 staining was significantly correlated with tumor size (P=0. 020,pT). Single factor analysis showed that HSP-90 was significantly associated with longer survival (P=0. 033). Multivariate analysis demonstrated that HSP-90 was highly expressed as an independent prognostic factor for gastric cancer (P=0. 026). Conclusion: the HSP-27,-60 and -90 and some clinical pathological parameters. These parameters is very important for the treatment of patients with gastric cancer. The high expression of HSP-90 in patients with gastric cancer were inde-pendent prognostic indicators.

A method was developed for the determination of four sulfa antibiotics in groundwater, soil and excreta using solid phase micro extraction disks coupled with high performance liquid chromatography. The influence of eluent, different solid phase micro extraction membranes on the recovery of sulfa antibiotics in groundwater was investigated and it was found that when using the mixture of methyl alcohol and 1 . 0% formic acid as eluent, HLB ( divinyl benzene-N-vinyl pyrrolidone polymer ) as extraction membranes, an optimal enrichment effect was obtained. Different pretreatment methods for the 3 kinds of samples abovementioned were also examined. It was found that the signal response values obtained by using mixture of methyl alcohol and 1 . 0% formic acid as base solution of standard or sample solution was higher 8-10 times than that by using methyl alcohol only. Under the optimal conditions, good linear relationships were obtained in the sulfa antibiotics concentrations of 0 . 005-10 . 0 mg/L with the correlation coefficients>0 . 9999;The detection limits of sulfathiazole ( ST ) , sulfadiazine ( SM ) , sulfamethazine ( SM2 ) , sulfamethoxazole ( SMX ) were 1 . 08 , 3. 56, 4. 63 and 1. 84 ng/L(S/N=3), respectively. The enrichment factors for four sulfa antibiotics were 4000 times with solid phase micro extraction disks. The RSD of matrix spiked samples were 0. 1%-0. 4%(n=7). The proposed method was applied to the determination of the four sulfa antibiotics in groundwater, soil and excreta with spiked recoveries of the four sulfa antibiotics in the range of 69 . 80%-117 . 60%.
