Three strategies for nephrologists are to recognize the signs of early diagnosis of chronic kidney disease ( CKD),to identify and treat risk factors of progression of CKD and to cure or slow-down the progress of end-stage renal disease (ESRD). The idea of individual therapies obtaining optimal clinical results in tumor treatment urged people to find and apply biomarkers for personalized diagnosis of the risk factors of CKD susceptibility and progression,which provide a rationale for pursuing personalized medicine.(Chin J Lab Med,2012,35:784-789)

Diabetic cardiomyopathy is one of the main causes of death in diabetic patients.Mitochondrial dysfunction plays a key role in the development of diabetic cardiomyopathy,and mitochondrial function depends on the stabilization of the mitochondrial membrane structure.Studies on the molecular alteration and the underlying mechanism of the cardiocyte mitochondrial membrane of the diabetic heart may give us deeper insights into diabetic cardiomyopathy,and help us make a breakthrough in the therapeutic strategies.

Objective Laboratory animal practitionres need further management through technical and capacity training.Methods Relying on the Laboratory Animal Center of University and its highly qualified faculty, a high-quality training base for laboratory animal practitioners has been set up.Results Based on the relevant laws and regulations about experimental animals, appropriate training outlines, different training books and courses were prepared and organized for different trainees.Focusing on the detailed and exact experiments, training base has put emphasis on the practical ability and operational skills.Conclusions How to regulate the training for laboratory animal practitioner by means of base training is discussed and tried out in this paper.

Objective To evaluate the serum rocalcitonin(PCT) determination in the diagnosis of emergency patients with fever . Methods 120emergencypatientswithfeverwereenrolledinthestudy,whoseserumsamplesweretestedbyusingelectrochemilu‐minescence immunoassay for PCT concentrations ,at the same time white blood cells(WBC) count and C reactive protein(CRP) were also determined .Bacterial culture results were used as gold standard for the diagnosis of bacterial infection .WBC>10 .0 × 109/L,CRP>10mg/L,PCT>0.5μg/Lwerethejudgmentcriteriafortheevaluationofthoseindicators.Results 73casesofpatients′bacteria culture results were positive ,47 patients′bacteria culture results were negative;63 cases of patients were with PCT ,WBC and CRP levels elevated at the same time;2 patients′WBC count elevated ,while PCT and CRP concentrations did not ;6 patients′serum PCT concentrations increased ,while WBC and CRP levels didn′t ;4 patients′serum PCT and CRP concentration increased , while WBC count didn′t ;35 patients′PCT ,WBC and CRP kept at low levels .Conclusion Serum PCT concentration could be used as an auxiliary diagnosis indicator in the diagnosis of emergency patients with fever .

Objective To observe the clinical efficacy of alprostadil, benazepril combined with Danqi Decoction and herbal enema in treatment of diabetic renal proteinuria.Methods Sixty cases of diabetic renal proteinuria patients were randomly divided into the control group and the experimental group.Each group was 30 cases.The control group was given alprostadil(0.2μg/mL,2 times per day) and benazepril(10 mg,one time per day), while the experimental group was given Danqi Decoction combined with herbal enema on the basis of the control group(one time per day).The urea nitrogen, serum creatinine, quantitative of proteinuria (in 24 hours) and the excretion of urinary micro-albumin of both groups were all tested after three weeks of continuous treatment.ResuIts After three weeks of treatment, the laboratory values of urea nitrogen, serum creatinine, quantitative of proteinuria in 24 hours of both groups were all improved compared with those before treatment(P<0.05).Furthermore, the quantitative of proteinuria(in 24 hours) of the experimental group was significantly less than that of the control group(P<0.05), and the excretion of urinary micro-albumin of the experimental group was significantly less than that of the control group(P<0.05).ConcIusion The therapy of alprostadil, benazepril combined with Danqi Decoction and herbal enema is effective for diabetic renal proteinuria patients, and can significantly reduce proteinuria and renal injury.

Objective To discuss the application effect of FMEA in reduction of unplanned extubation of PICC.Methods FMEA was applied to find out the failure mode of unplanned extubation of PICC,and then assessed it from three dimensions,which were the likelihood of occurrence,the possibility of being discovered,and the seriousness of the failure,and then calculated the RPN values,risk priority,and plan optimization process,at the last made a proactive behavior intervention.81 patients were selected as the control group before the application of FMEA and 98 patients were set as the experimental group after the application of FMEA.The incidence of unplanned extubation was compared between two groups.Results There was statistically significant difference in unplanned extubation between two groups.Conclusions Application of FMEA can reduce the rate of unplanned extubation of PICC.

To guarantee the basic quality of nursing service, many countries have carried out the licensure examinations for registered nurses, which are used not only to evaluate the quality of nursing education but also to guide the development of education. This paper reviewed the process of the establishment of the systems, and outlined the features of the examinations in content design, organization and implementation, improvement and development trends in both China and America in order to improve ours.

al blood lactic acid monitoring is simple, easy and practical to use in predicting prognosis of ICU patients sensitively.

Clinical surgical teaching is an important course of undergraduate teaching.Aiming at the problem of disconnection between operation and case in traditional video teaching and observing teaching in operation room,a new model of live surgery teaching based on case teaching was launched:intraoperative diagnosis and preoperative medical history collection were combined;intraoperative surgical anatomy and similar comparative study;teaching surgery were combined with pathology and postoperative adjuvant therapy.Through the questionnaire it was found that all of the students were satisfied with live surgery teaching,96.5％ of the students believed the model would contribute to their understanding of textbook knowledge and memory,and 94.8％ of the students thought the model could improve their interest in clinical learning.

Hypoxia results from long-term anti-angiogenic therapy and can stimulate hypoxia-inducible factors (HIFs). HIF-induced hy-poxia signaling is involved in various steps in tumor invasive-metastatic cascade. On the one hand, HIFs regulate epithelial-mesenchy-mal transition. On the other hand, the characteristics of pericytes around vessels and the links among endothelial cells can change;thus, tumor cells can more easily intravasate into blood vessels, survive in peripheral blood, and then reach specific organs, ultimately resulting in metastasis. This review discusses the emerging mechanisms of long-term anti-angiogenic therapy and the occurrence of metastasis.
