Objective:To investigate the consumption situation and cognition of health care products in hospitalized patients, ana-lyze the problems in purchasing and use of health care products to provide evidence for the correct selection and rational use of health care products. Methods:The investigation and analysis was conducted with an anonymous questionnaire on awareness and consumption situation of health care products in hospitalized patients. Results:The survey received 129 valid questionnaires, and more than 1/3 re-spondents did not know the differences between health care products and medicines, and 27. 91％ of them treated diseases with health care products, 57. 36％ of them purchased health care products per month, and 96. 12％ of them thought the efficacy of health care products were inconsistent with the advertising efficacy. Conclusion:Patients cannot distinguish health care products from medicines, and lack of trust in the health care products market. Corresponding measures should be performed to help patients purchase and use of health care products and safeguard their legitimate rights and interests.

Mortality is a key index for assessing technical level and treatment quality of hospital. We filtered and analyzed the literatures about the influence of nurse factors on patient mortality out of China in recent years to guide the study within China. We found the nurse factors impacting mortality included workload, configuration of nursing staff, education status and working environment. Those findings point out the direction of the research on relationship between nurse factors and patient mortality in China, which has great significance.

Objective To observe the expression and transcription of MART-1 in human uveal melanoma cell lines 92-1,92-2,Ocm3,Me1285,as well as the possible effect ofmethylation on its expression.Methods The cell lines 92-1,92-2,Ocm3 and Me1285 were cultured routinely and tested for MART-1 expression at protein and mRNA level by FACS analysis,Western blot and RT-PCR respectively.Methylation status of the MART-1 promoter region in all the cell lines were checked by Southern blots of DNA digested with methylation sensitive restriction enzymes.Results As observed in FACS analysis and Western blot,92-1,92-2 and Ocm3 were MART-1 positive cell lines while Me1285 was negative cell line.Consistent with protein analysis,92-1 and Ocm3 cell lines showed MART-1 specific PCR products and there was no product in Me1285 cell line in RT-PCR.The MART-1 positive cell lines,92-1,92-2,and Ocm3 show methylation at the MspⅠ/Hpa Ⅱ site,and the Nru Ⅰ sites of all positive cell lines are not methylated.The MART-1 negative cell line Me1285 shows hyperrnethylation at the Nru Ⅰ site and the Msp Ⅰ/Hpa Ⅱ site is not methylated.Conclusions MART-1 could be expressed in human uveal melanoma cell lines 92-1,92-2 and Ocm3.The change of methylation status of MART-1 promoter may correlate with the transcription of MART-1.

Hepatocellular carcinoma (HCC) has high morbidity and mortality rates worldwide, and due to the complexity of the development of HCC, the management strategy for HCC has not been completely unified. During the past decade, the treatment of HCC has developed into a multidisciplinary and multimodality therapy centered on surgical operation. Besides hepatectomy and liver transplantation, ablation therapy is another radical treatment, and at present, it can be used as the first-line treatment regimen for HCC patients who have a tumor diameter of ＜3 cm and cannot undergo liver transplantation. Transarterial chemoembolization is the preferred treatment for advanced HCC not suitable for radical treatment. Molecular targeted therapy is mainly used in patients who are diagnosed with advanced HCC or progress to advanced HCC after treatment failures. Cellular immunotherapy is a new treatment for HCC and can help patients with progressive HCC to achieve good remission rate and survival benefit. A deep understanding of the features of each treatment method for HCC, development of individualized treatment regimens, and rational multimodality therapy for HCC can help to improve the overall therapeutic outcome of HCC.

AIM:To investigate the RNA oxidative damage in human gastric cancer tissue and para-carcinoma tissue for exploring the role of RNA oxidation in the occurrence of gastric cancer .METHODS:Immunohistochemical ob-servation and LC-MS/MS analysis were performed in 61 cases of gastric carcinoma .The position and concentration of 8-oxoguanosine ( 8-oxoGsn ) were detected , respectively . RESULTS: The results of immunohistochemical observation showed that 8-oxoGsn was obviously up-regulated in the gastric cancer .The positive staining mainly accumulated in the cy-toplasm of the tumor cells .The results of mass spectrometry showed that the level of 8-oxoGsn in the gastric cancer tissues was higher than that in the para-carcinoma tissues (P<0.05).CONCLUSION:8-oxoGsn is up-regulated in gastric canc-er.RNA oxidative damage may play important roles in the occurrence of gastric cancer .

Objective To observe the value of 3.0T multimodal MRI for preoperative evaluation of T stage and therapeutic efficacy of neoadjuvant for rectal cancer.Methods 3.0T multimodal MRI data,including T1WI,T2WI/diffusion weighted imaging(DWI),dynamic contrast enhanced MRI(DCE-MRI)and intravoxel incoherent motion DWI(IVIM-DWI)of 150 patients with rectal cancer were retrospectively analyzed,and the value of different sequences for evaluating T stage and therapeutic efficacy of neoadjuvant for rectal cancer were assessed.Results The sensitivity,specificity and accuracy of T1WI,T2WI/DWI,DCE-MRI and IVIM-DWI for evaluating T1-T2 and T3-T4 stage rectal cancer were all significantly different(all P＜0.05).The diagnostic efficacy of DCE-MRI and IVIM-DWI were all higher than that of T1WI and T2WI/DWI(all P＜0.05).Combination evaluation of DCE-MRI and IVIM-DWI for T stage of rectal cancer had good consistency with pathological results(Kappa=0.943,P＜0.05).Significant differences of volume transfer constant(Ktrans),true diffusion coefficient(D)and apparent diffusion coefficient(ADC)were found among different T stage rectal cancers(all P＜0.05).Totally 80 patients received neoadjuvant therapy,and significant differences of Ktrans,D and ADC were noticed between patients with good(n=32)or poor efficacy(n=48)(all P＜0.05).The area under the curve(AUC)of Ktrans,D and ADC for evaluating therapeutic efficacy of neoadjuvant for rectal cancer was 0.774,0.837 and 0.758,respectively,of the combination of above three was 0.929,higher than that of single indexes(all P＜0.05).Conclusion Combination of 3.0T DCE-MRI and IVIM-DWI was helpful for preoperative evaluating T stage and therapeutic efficacy of neoadjuvant for rectal cancer.

Objective To assess right ventricular systolic function using real-time three-dimensional right ventricular quantitative analysis (RT-3DRVQ) in patients with coronary artery disease (CAD) complicating left heart failure. Methods Sixty-eight patients diagnosed with CAD and left heart failure were selected as the case group.Among them,38 individuals were associated with pulmonary hypertension (PH) and 30 were without. Another 30 healthy people were recruited as control group. Conventional echocardiographic parameters,as well free wall and septum longitudinal strains of right ventricle were evaluated in all subjects. Results Patients with left heart failure had significant lower strain values than control group( P <0.001).In case group,three-dimensional derived right ventricular free wall longitudinal strain (3D-FWLS) had strongly correlation with right ventricular ejection fraction ( r = -0.877, P <0.001). The patients with PH had also significantly reduced 3D-FWLS values compared with patients without PH ( P < 0.01),and the area under the curve was 0.726 using ROC method to predict patients with PH.Conclusions RT-3DRVQ could be recognized as a good technology to evaluate right ventricular systolic function,which would provide valuable information for clinical decision-making.
