Objective: Observing the effect of injecting 5- Fu into the mass of breast hyper-plasia. Methods: We randomly divide the 80 mastopathy patients into two groups ,40 patients ac-cepted the 5- Fu local injection (experiment group),and 40 patients taken orally rubixiaopian and ta-moxifen(control group). The clinical effects of the breast pain and breast lump were observed. Re-sults: The total effect of 5- Fu local injection into the lump of the mastopathy patients was 92.5 % , while control group was 75.0% , its difference was significant(P0.05)in the treatment of mastopathy lump. Conclusion: 5- Fu local injection had obvious effects to breast pain and breast lump of mastopathy.

Aim To amplify P30 gene and express P30 fusion with GST Methods P30 gene was smplified from T. gondii chromosomal DNA and ligated to pGEM-T and pGEX-4T-1. Screening-positive recombinants were induced for expression, which was subsequently detected by WB Results P30 gene was amplified and GST-fusion was confirmed by rabbit antiT. gondii serum. Conclusions The construction of pGEM-T-P30 and pGEX-4T-1-P30, together with the recombinant protein would lay a base for further investigation of P30 at a molecule-level and application to diagnosis and vaccination

Recently, microRNAs (miRNAs) have been shown to be involved in multiple biological pathways that can influence tumor progression and metastasis and they can serve as prognostic biomarkers in many cancers. The present study examined the prognostic significance of miR-215 in cervical cancer. The paraffin-embedded paired cervical scrape samples and tumor tissue samples from 302 patients with stage II cervical cancer were detected for the expression of miR-215 by using qRT-PCR. A miR-215-based classifier was established by using the Cox regression model. The prognostic and predictive accuracy of this classifier was determined in both the internal testing group of 138 patients, and the external independent group of 280 patients. Moreover, cervical cancer HeLa cells overexpressing miR-215 (HeLa-miR-215) were constructed and subcutaneously injected into the nude mice to examine the effect of miR-215 on tumor growth and metastasis in vivo. The results showed that the expression level of miR-215 was significantly higher in cervical cancer tissues than in paired normal tissues (P<0.0001). When patients were classified into high- and low-risk cancer progression groups according to miR-215 level, the 5-year disease-free survival in high- and low-risk groups were 43% (95% CI: 32.1-51.6) and 67% (95% CI: 48.6-77.3) (hazard ratio [HR] 2.02, 95% CI: 1.16-3.52; P=0.013) respectively. Moreover, the expression level of miR-215 was negatively associated with survival rate in patients at TNM stage T3 (HR: 3.317; 95% CI: 1.18-5.14, P=0.017) and TNM stage T4 (HR: 3.48; 95% CI: 1.49-4.45, P=0.008). Tumor volume in nude mice injected with HeLa-miR-215 cells was significantly larger than that in mice injected with control HeLa cells. It was concluded that the expression level of miR-215 is associated with cervical tumor progression and worse survival rate, suggesting that it may serve as a potential prognostic marker to identify patients at higher risk of recurrence.

Objective To investigate the effect of resistance nodulation division (RND) efflux pumps on reduced susceptibility to tigecycline in carbapenem-resistant Acinetobacter baumanii.Methods Totally 631 isolates of Acinetobacter baumanii were collected from 16 hospitals in 7 provinces in 2010.Genes oxa-51 and oxa-23 were detected by PCR method,and the ST profiles were determined by multilocus sequence typing (MLST).The disk susceptibility assay was used to determine the inhibition zone diameters of β-lactams,aminoglycosides,macrolides,tetracyclines,carbapenems,tigecycline and polymyxin.The minimum inhibitory concentration (MIC) of tigecycline was determined by E-test in strains with inhibition zone diameters ≤ 12 mm on tigecycline.The expression of operon genes adeB,adeG and adeJ was determined with efflux pump inhibitor NMP (N-methyl-2-pyrrolidone) for detection of efflux pump inhibitor phenotype.The isolates of Acinetobacter baumanii which were resistant both to tigecycline and carbapenems and with the inhibited phenotype of efflux pump inhibitor were collected as the experiment group,the isolates which were susceptible to tigecycline but resistant to carbapenems were collected as the control group,and ATCC 19606 was used as the reference strain.The expressions of adeABC,adeFGH and adeIJK were quantified by q-PCR at the transcriptional level.Genes adeR,adeS and adeL were amplified and sequenced using PCR method to find polymorphic locus and insertion sequences.Results There were 32 isolates of Acinetobacter baumanii with reduced susceptibility to tigecycline and carbapenem-resistant.Eight isolates were with the inhibited phenotype by efflux pump inhibitor.And 4 strains which were susceptible to tigecycline but resistant to carbapenems were selected as the control.The expressions of adeABC in A518,Z1219 and A527 of experiment group were 13-fold,5-fold and 7-fold higher than reference strain ATCC19606,respectively.The expressions of adeFGH and adeIJK were up-regulated slightly in some isolates.Transcript of adeABC was not found in control group strains A207 and A1731,and the expressions of adeABC,adeFGH and adeIJK were not up-regulated in other isolates.The single nucleotide polymorphism (SNP) was detected in adeR (E220K) and adeS (A130D),respectively.ISAab1 insertion sequence was identified in adeS of adeABC-over expressed isolates.No mutation was found in adeL.Conclusion High expression of adeABC pump may play an important role in tigecycline resistance in carbapenem-resistant Acinetobacter baumannii,mainly due to the insertion of ISAba1 sequence in its regulator gene adeS,but other mechanism of tigecycline resistance may not be excluded.

Objective To explore the effect of empathy nursing on anxiety,depression and expectation of patients with myocardial infarction.Methods In our study,47 patients with myocardial infarction in the department of cardiology of our hospital from August 2013 to July 2014 were assigned as the control group and another 47 patients with the same disease during August 2014 to July 2015 as the study group.The control group received conventional nursing treatment and the study empathy nursing in addition to the conventional nursing.The two groups were compared in terms of anxiety,depression and expectation using Zung anxiety self rating scale (SAS),depression self rating scale (SDS) and Herth hope index (HHI).Results On admission,the patients in the two groups showed no differences in the levels of anxiety,depression and expectation (P＞0.05).After intervention,the levels of anxiety and depression in the study were significantly lower than those in the control group,but the level of expectation was higher (all P＜0.05).Conclusion Empathy nursing is effective for the relief of anxiety and depression in the patients with myocardial infarction as well as for their enhanced expectation for prognosis.

A perfect clinical trial must nave a solid study design, strict conduction, complete quality control, non-interference of statistical result, and acceptable risk-benefit ratio. To reach the target, the quality control (QC) should be performed from the study design to conduction, from the analysis to conclusion. We discuss the relationship between data management and biostatistics from the statistical point of view, and emphasize the importance of the statistical concept and methods in the improvement of data quality in clinical data management.

Characteristics and measurement principles of reference methods in clinical biochemistry were described.Implementation of reference systems is one of the most effective approaches to improve the accuracy and comparability of clinical laboratory test results.Reference methods are the key components of reference systems.Reference methods should have measurement uncertainties that meet the requirements of the intended use,and thus should be based on reliable measurement principles.For the well-defined biochemistry analytes,reference methods have been almost all based on instrumental analysis.Isotope dilution mass spectrometry (ID/MS) is considered most reliable and has been the major analytical principle of the reference methods.ID/MS analysis is accurate but expensive.Use of other validated instrumental analyses as reference measurement principles would be justified.
