Objective To perform comparative proteomic analysis of human ovarian cancer cell lines for detecting platinum-resistance associated proteins.Methods The total proteins of two sensitive (SKOV3 and A2780)and four resistant(SKOV3/CDDP,SKOV3/CBP,A2780/CDDP and A2780/CBP) human ovarian cancer cell lines were separated by two-dimensional gel electrophoresis(2-DE).The differentially expressed proteins were analyzed using image analysis software,stained with Coomassie Brilliant Blue,then identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS)and database searching.The mRNA and protein levels of the differentially expressed protein which was most significant in all of the four resistant cell lines were validated by RT-PCR and western blotting,respectively.Results Five proteins were found to be significant in four cell lines. Annexin A3 and destrin were up-regulated and nicotinamide-adenine dinucleotide phosphate(NADP)- dependent isocitrate dehydrogenase 1 was down-regulated in all the four resistant samples.Glutathione transferase omega 1 had an increased expression in the other three resistant cell lines except for SKOV3/CBP in which its expression was not changed.However,cofilin 1 represented a different trend.In the two resistant sublines of SKOV3,eofilin 1 had a down-regulation,but it had an up-regulation in the cell lines induced from SKOV3.The expression of annexin A3 was up-regulated by 3-20 fold and the results of RT- PCR and western blotting showed complete consistency with that by 2-DE.Conclusions Proteomic techniques are useful to the identification of the resistance-associated proteins in ovarian cancer platinum- resistant cell lines and five candidates have been found.The five differential proteins might become hopeful candidate biomarkers for resistance.

Objective To investigate the change in intracranial pressure (ICP) during induction of anesthesia with fentanyl, propofol and succinylcholine in neurosurgical patients by measuring cerebral spinal fluid (CSF) pressure at the level of lumbar spine.Methods Twenty ASA Ⅰ or Ⅱ patients (9 males, 11 females) aged 24-54 yrs scheduled for elective craniotomy for intracranial tumor were included in this study. Lumbar puncture was performed at L2,3 or L3,4 interspace with an epidural needle through which an epidural catheter was placed in the subarachnoid space to allow measurement of lumbar CSF pressure. Anesthesia was induced with fentanyl 2-3 ?g?kg-1 followed by propofol 2 mg?kg-1 and succinylcholine 1.5 mg?kg-1. CSF pressure was recorded before induction of anesthesia (baseline value), at 5 min after intravenous fentanyl injection, 1, 2, and 3 min after propofol injection, during fasciculation of muscle and immediately after intubation.Results CSF pressure was significantly decreased at 1, 2 and 3 min after i.v. propofol and during muscle fasciculation. The CSF pressure was lowest at 3 min after propofol injection. Tracheal intubation did not result in significant increase in CSF pressure as compared with the baseline value before induction. Conclusion Intracranial pressure is decreased during induction of anesthesia with fentanyl, propofol and succinylcholine in neurosurgical patients and the adverse effect of tracheal intubation on ICP is effectively blunted.

Purpose:To study the activity of toremifene and its synergistic effect with anti-tumor drugs on human lung adenocarcinoma cell line A549,which might be expected to provide a new mode of therapy for the clinical management of lung cancer.Methods:The cytotoxic effects of these agents on human lung cancer cell line A549 were measured by a tet- razolium-based volorimetric assay (MTT assay).Results:Toremifene can inhibit the growth of A549 cell directly.The A value of the low dose toremifene combined with anti-tumor drugs were lower than that of anti-tumor drugs alone.Toremifene combined with VCR,ADM,DDP and VP-16 showed better effects.Conclusions:Toremifene combined with chemotherapy drugs shows significant synergistic anti-tumor effect on A549 cell.This might provide experimental evidence for lung cancer therapy.

Cyclophosphamide (CPA) is the most common alkylating antineoplastic agent, as well as a strong immunosuppressant that is frequently applied to autoimmune diseases and organ transplantation. It is metabolized by cytochrome P450 oxidases (CYPs) to its active metabolite which played a critical role in therapy. CPA has serious and even fatal side effects, and its efficacy and adverse reactions are significantly varied among individuals. In this review, the association of the genetic polymorphisms in the metabolic enzymes and transporters involved in the disposition of CPA with the efficacy and adverse effects of CPA were summarized, thereby providing fundamental reference for further pharmacogenomic study of CPA.

Objective To explore the clinical features of children infected with macrolide-resistant (MR) Mycoplasma pneumonia(MP) isolates and genetic typing of all isolates.Methods Polymerase chain reaction(PCR) of MP positive in 96 nasopharyngeal or bronchoalveolar lavage fluid (BALF) samples were collected from patients diagnosed as MP pneumonia in the Affiliated Children's Hospital of the Capital Institute of Pediatrics from January 2013 to October 2015.Fifty-five cases were male,41 cases were female;19 cases (19.8％) were 1 to 3 years old,18 cases (18.7％) were more than 3 to 5 years old,59 cases(61.5％) were more than 5 to 13 years and 2 months old.These samples were tested for MR associated mutations in the 23S rRNA of MP,and were divided into the MR group and the macrolide-sensitive (MS) group.Furthermore,the genotype of all the isolates were performed by conducting P1-restriction fragment length polymorphism(P1-RFLP) analysis and multiple-locus variable-number tandem-repeat analysis (MLVA) method.The clinical characteristics including the age,gender,hospitalization duration,symptoms,signs,fever duration,fever duration after macrolide therapy,white blood cell count,C-reactive protein (CRP),chest X-ray and/or chest computed tomography,which were compared between different groups.SPSS 11.5 software was used to analyze the statistical data.Statistical significance was determined at the 0.05 level of a two-tailed test.Results MR mutations were identified in the 23S rRNA gene in 81 specimens (84％),and the 96 specimens were divided into MR group(81 cases) and MS group (15 cases).There were statistical differences in fever duration,hospitalization duration,the incidence of complications and CRP level between the MR group and MS group (t =2.061,Z =-3.368,x2 =5.856,Z =-2.165,all P ＜ 0.05).There were no statistical differences in age,white blood cell count,consolidation percentage on chest radiography and fever duration after macrolide therapy(all P ＞ 0.05).All the 96 isolates were performed by adopting P1-RFLP typing,but 5 isolates were not typed successfully,while 81 cases (89.0％) isolates were typed as P1-Ⅰ and 10 isolates(11％) were typed as P1-Ⅱ c.The hospitalization duration and the fever duration after macrolide therapy in the P1-Ⅰ were longer than the P1-Ⅱ c group,and the difference was statistically significant (Z =-2.197,2.237,all P ＜ 0.05).There were no statistical differences in age,fever duration,white blood cell count,CRP level,consolidation percentage on chest radiography and the incidence of complications (all P ＞ 0.05).Seventy-three cases (90％) of P1-Ⅰ group were MR isolates,8 cases (10％) were MS isolates;3 cases (30％) of the P1-]Ⅱ c group were MR isolates,7 cases (70％) were MS isolates.The MR isolates in P1-Ⅰ group were much more than P1-Ⅱ c group.There was obvious statistical difference in the proportion of MR isolates between 2 groups (x2 =19.209,P ＜ 0.01).All the 96 isolates were performed by modified MLVA typing,82 cases(85.5％) were typed as M4-5-7-2,11 cases(11.5％) were typed as M3-5-6-2,1 case (1.0％) was typed as M4-5-5-2,and 2 cases (2.0％) were typed as M4-5-6-2.Because there were less cases of the M4-5-5-2 and M4-5-6-2 type,only the clinical data of M4-5-7-2 and M3-5-6-2 group were compared.The hospitalization duration and the fever duration after macrolide therapy in the M4-5-7-2 group were longer than the M3-5-6-2 group,and the difference was statistically significant(Z =-2.406,-4.472,all P ＜ 0.05).There were no statistical differences in age,fever duration,white blood cell count,CRP level,consolidation percentage on chest radiography and the incidence of complications(all P ＞ 0.05).Seventy-four cases (90％) of the M4-5-7-2 group were MR isolates,8 cases (10％) were MS isolates;4 cases (36％) of the M3-5-6-2 group were MR isolates,7 cases (64％) were MS isolates.The MR isolates in M4-5-7-2 group were much more than M3-5-6-2 group.There was obviously statistical difference in the proportion of MR isolates between 2 groups (x2 =17.022,P ＜ 0.01).Conclusions In the MR group,the children had longer fever duration and hospitalization duration,higher incidence of complications and higher CRP level than those in the MS group.The MR rates of MP in China was high.P1-Ⅰ and M4-5-7-2 are the predominate genotypes.There may be a correlation between genotype and MR.

Objective To investigate the relationship between eosinophil and in-stent restenosis in acute coronary syndrome patients. Methods One hundred and fifity-one ACS cases werenenrolled in this study. According to the results of coronary angiography (the stented segment lumen loss over 50% was judged to be ISR), patients were divided into the restenosis group and the non-restenosis group. Results Based on the logistic analysis, no significant association was found between eosinophil and ISR, and even after adjustment of related risk factors (P > 0.05). The stratification analysis showed that the high level of eosinophil might increase the risk of ISR in ACS patients with history of hypertension (P = 0.038) and myocardial infarction (P = 0.032). Conclusion Eosinophil may be associated with the risk of ISR in ACS patients with history of hypertension and myocardial infarction. The underlying mechanisms need to be elucidated in further study.

Objective To investigate the correlation between ankle-brachial index and ultrasonography in lower ex- tremities vascular in type 2 diabetic patients.Methods 218 type 2 diabetic patients were enrolled,and ankle-brachial index(ABI)measurements and uhrasonography in lower extremities vascular were performed in all patients.Lower extremi- ties vascular disease(LEVD)were divided into six species according to the uhrasonography results and scored in accord- ante with its serious degree,then investigate the correlation between ABI and uhrasonography results score.All patients were divided into deferent groups according to uhrasonography results and ABI range,and then compared their deference. Results The lower the ABI,the more serious of the LEVD showed by ultrasonography.ABI and ultrasonic inspection score was significantly negatively correlated(r=-0.65,P
