RESUMO
Objective:To discuss application effect of risk management in medical device management of hospital and its impact on management quality.Methods:9800 medical devices of hospital were selected and divided into routine management group (the corresponding medical devices came from the term of 2014 year to 2015 year, n=4900) and risk management group (the corresponding medical devices came from the term of 2014 year to 2015 year, n=4900) according to different management method.The arrangement and placement of device, the specification and quantity of device, the placement of accessories and the intact situation of widgets of the two groups were recorded and calculated as statistics method.A self-designed questionnaire was adopted to assess these situations included classification error, incompetence, loss of device, undersupply, instrument damage, the timeliness degree of supply, the timeliness degree of withdrawing and quality of packaging in the management process for medical devices.And the management effects of two groups and the corresponding influences of them for curative effect were further compared.Results:The arrangement and placement of medical device, the different specification and quantity of device, the placement of accessories, intact rate of widgets of risk management group were significantly higher than those of■timeliness degree of supply, the timeliness degree of withdrawing and quality of packaging of risk management group post management were significantly higher than those of routine group (t=20.394, t=21.847, t=16.481, P<0.05) .Conclusion:The effect of risk management that is used in medical equipment management of hospital is significant, and it contribute to improve the management quality for medical apparatus and instruments and reduce the error rate of instruments, and it can ensure the safety usage of them in hospital.
RESUMO
In the context of precision medicine, although individual treatment of breast cancer under the guidance of molecular classi-fication has become the norm, a precision treatment program with increased efficiency and quality is still required. Compared with the traditional real-time fluorescent quantitative polymerase chain reaction (PCR), the droplet digital PCR (ddPCR) has obvious advantages in the detection of rare mutations and copy number variations, as well as the integration with the second-generation-sequencing tech-nology. This paper reviews the application of a ddPCR platform in different breast cancer subtypes and explores new horizons of breast cancer research through the ddPCR technology.
RESUMO
Objective To investigate the expression of hepsin and its role in the pathogenesis of breast infiltrating ductal cancer ( BIDC) .Methods The expression level of hepsin was examined by immunobloting and immunohistochemistry in breast tissue samples from 8 healthy controls and 139 patients with BIDC,respectively. The correlation between hepsin level and its significance in clinical pathology of BIDC was assessed by statistical analysis.Results High level of hepsin was detected in nearly 70.5 percent of BIDC samples(98 out of 139)by immunobloting and immunohistochemistry , while the level of hepsin was relatively low or hardly detectable in healthy controls.In addition,there was a significant correlation between hepsin level and clinical stages as well as the level of histological differentiation of BIDC .Conclusion Increased expression of hepsin might play an impor-tant role in pathogenesis and progression of BIDC .The level of hepsin is positively correlated to clinical stages of BIDC,but negatively correlated with the level of histological differentiation of BIDC .
RESUMO
Objective Inhibitor of growth 1 ( ING1 ) gene has been identified as a novel candidate of tumor suppressor gene .Over-expression of ING1 plays well-established roles in numerous cell processes ,inclu-ding DNA repair and cell apoptosis .Our study is to investigate the clinical significances of expression of ING 1 in colorectal cancer ( CRC) .Methods The mRNA level of ING1 in 82 matched samples comprising primary CRC and paired non-cancerous mucosa were detected and compared by quantitative RT -PCR.Then the correlations of mRNA level of ING1 with the clinicopathological characteristics and prognosis of patients with CRC were ana -lyzed.Results (1)In the same matched tissues,the expression level of ING1 was significantly higher in normal tissues than that in cancer tissues.(2)mRNA expression of ING1 was associated with certain clinical -pathologic variables such as tumor infiltrating level ,lymphatic metastasis,distant metastasis and advancing TNM stage .(3) We obtained the expression levels ratio of cancer tissue and normal tissue and found the lower ratio has a lower Disease-Free Survival(DFS)(P<0.0001).(4)ING1,as a candidate of tumor suppressor gene ,remained a sta-tistically-significant prognostic marker in the Cox regression analysis .Conclusion Down-regulation of ING1 may be correlated tightly with the occurrence and progression of sporadic colorectal cancer .Its expression level can be used to predict prognosis of CRC .
