Objective To study the dilution model of the early pregnancy test strip for the quantitative detection of serumβ-hu-man chorionic gonadotropin(β-hCG)level by the Abbot AxSYM detection system and its application.Methods The detection re-sults of serumβ-hCG level in 5 612 outpatients and inpatients of the internal medicine department and the gynecology and obstetrics department during 5 years were retrospectively analyzed.In addtion,234 serum samples from the patients were collected for prelimi-narily determining the serumβ-hCG level by the early regnancy test strip and then the quantitative detection of serumβ-hCG level was detected by the Abbot AxSYM detection system.Results The retrospective analysis showed that 241 cases(4.6%)were low-age pregnant women.The qualitative screening was necessary.The screening model was successfully established.But one thing to note was that the part of serum sample needed to be taken out and put into another tube for determination.Conclusion Establishing the rational and effective dilution interpretation model of early pregnancy test strip for screening serumβ-hCG can bring the econom-ic and time benifits for the routine detection work of the Abbot AxSYM detection system.

Objective To analyze the distribution and drug resistance of Escherichia coli which separated from clinical.Methods Collecting the bacteria specimens to separating and training Escherichia coli,and then screening and monitoring drug susceptibility by The Dark Horse Microbial Analysis System,from January 2010 to July 2011.Results The Escherichia coli 486 strains which separated from clinical,the male 297 cases,female 189 cases,secretion separation 236 strains was the highest rate (48.56％),sputum 165 strains (33.95％),urine 39 strains (8.02％),and the rest of the sample 46 strains (9.47％).ESBLs 198 strains,which resistance in 19 antibiotics were higher than Escherichia coli,and it was multiple antibiotic resistance such as Aminoglycoside,Quinolone etc; Escherichia coli strains were sensitive to imipenem.Conclusion Escherichia coli which separated in surgery,respiratory tract,and urinary had a large proportion,and Resistance of Escherichia coli was serious,we should according to the Drug sensitivity of Escherichia coli,choose reasonable application of antibiotics,especially the ESBLs strains.We should strengthen the resistance testing,to provide reference for clinical rational drug use.

MicroRNA-451 (miR-451) is significantly lowly expressed in glioma,gastric cancer,colorectal cancer,liver cancer and other tumor tissues.Upregulation of miR-451 can significantly inhibit tumor cell proliferation,invasion and metastasis as well as increasing tumor cell apoptosis and improving radiotherapy and chemotherapy sensitivity and other biological effects.

The diffuse large B cell lymphoma (DLBCL) is the most common adult non-hodgkin lymphoma.At present,rituximab in combination with CHOP program has significantly improved the prognosis of DLBCL,and about 50％ of the DLBCL can be cured.However,due to the heterogeneity of the tumor,the refractory and relapsed DLBCL is still lack of effective treatment methods.With the application of gene expression profile (GEP) and the thorough research of the activation of lymphoma cells signal way,a lot of potential therapeutic targets have been found.

Objective To determine the sites of action of propofol and isoflurane on somatosensory pathway using median nerve somatosensory evoked potential(MnSSEP) .Methods Twenty-six ASA I - II patients aged 20-50 yrs were randomly divided into two groups: I propofol group( n = 13) and H isoflurane group( n = 13) .In propofol group patients received propofol infusion at a rate of 10 mg?kg-1?h-1 .Oxygen was administered via mask and respiration was assisted or controlled to maintain SpO2 at 96%-100% and PETCO2 at 35-45 mm Hg. The propofol infusion was continued until the patient failed to respond to verbal command. Six minutes later if the patient was still breathing spontaneously, the rate of propofol infusion was increased to 20-40 mg?kg-1?h-1 . In isoflurane group anesthesia was induced with propofol 2 mg ? kg-1 and intubation was facilitated by succinylcholine and anesthesia was maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. The end-tidal isoflurane concentration was maintained at 0.5,1.0 and 1.5 MAC. Each concentration was maintained for 15 minutes. MAP, HR, SpO2,PCTCO2, T0(naso-pharyngeal) and BIS were continuously monitored. MnSSEP( Viking IV D type) was measured and recorded before induction of anesthesia(baseline) and in propofol group when patients became unconscious and apneic; in isoflurane group when end-tidal isoflurane reached 0.5,1.0 and 1.5 MAC.Results In group I there was no change in both latencies and amplitudes of N9 and N13'.With increasing infusion rate, propofol gradually prolonged the latencies and decreased the amplitudes of N60, P45, N35, N20 and P25 waves. In isoflurane group there was no change in the latencies and amplitudes of N9. There was no change in the latencies of N13', but the amplitudes decreased at 1.0 and 1.5 MAC. With increasing concentration, isoflurane gradually prolonged the latencies and decreased the amplitudes of P45, N60, N35, N20 and P25 waves. At 1.5 MAC the inter-peak latencies between N13'-N20 and N13'-P25 were prolonged. Conclusions The sites of action of different infusion rates of propofol and different concentrations of isoflurane are different on somatosensory pathway. The higher the doses, more widespread are the sites of action.

This paper,starting with sociology,mainly analyzes the factors which affect the college curriculum settings from such aspects as politics and ideology,economy and technology development level,educational thinking and perceptions as well as cultural tradition,which will be useful for reference on college curriculum settings.

Autoantibodies are useful laboratory parameters for diagnosis of autoimmune diseases (AID).Methods for the detection of autoantibodies have achieved quantitative or semi-quantitative to some extent.Furthermore,with the development of detection technology,high-throughout and quantitative technology has been the trend in autoantibody measurement.Compared with qualitative results,the quantitative ones may provide more values for diagnosis,prediction,prognosis and therapeutic monitoring for AID.Therefore,although quantitative technology of autoantibodies is still faced a number of challenges,the detection for autoantibodies has come into the era of quantitation.

Objective To analyze the mental health status and personality characteristic of hyperplasia of breast,so as to provide sound scientific basis for enhancing the quality of life of those patients.Methods Assessments were made by using Symptoms Checklist 90 (SCL-90)and 16 Personality Factor Questionnaire (16-PF) for the mammary gland hyperplasia patients and the normal,and data were analyzed with SAS 9.2.Results (1)Significant differences were found in the scores of somatization,compulsion,sensitivity,depression,terror and paranoid between the byperplasia of breast and heahhy subjects.(2)Multivariate and unconditional Logistic regression analysis revealed that the protective factor of psychosomatic symptoms is the warmth stability and perfectionism which factor regression coefficient was negative; the risk factor of psychosomatic symptoms was the dominance,suspicion,apprehension and tension which factor regression coefficient was negative.Conclusions There are various psychological problems which affected by personality characteristic in the patients with breast hyperplasia,treatment should be optimized based on the personality characteristics of patients with breast hyperplasia,including changing negative attribution model,disseminating preventive knowledge,and finally improve the mental health condition of patients with breast hyperplasia.
