Through expounding the definition of appreciate inquire,this paper discussed its principles when usedin medical humanities education including constructionism,simultaneity,poetry,preconception and optimism.Guided by optimistic themes,the benign development of medical humanistic education was realized by 4D circulation mode (discovery,dream,design,andrealization) of appreciative inquiry summit talks.

Poor communication between medical staff and patients is the main cause of medical disputes,and the clear emotional recognition and reasonable response of the patient needs psychology training and practice.Balint groups can create a good support environment and is an effective way to improve the communication ability and professional growth for medical staff.

Due to the shortcomings of traditional medical professionalism education,coupled with the impact of the reality,medical students' professional spirit produced some phenomenon in clinical practice such as weak professional faith,lack of professional value,poor career cognitive and so on.If medical professionalism education wants to make mental shaping function in medical students who are in the clinical practice,the traditional classroom teaching must be combined with Internet technology and thinking.On the one hand,Internet renovation must be applied to teaching system of systematic classroom teaching,teaching content of practicality,and extension of classroom,and so on.On the other hand,it should vigorously explore new way of Internet learning such as Moocs,micro-course online video,Network teaching center platform,live courses,and so forth.At the same time,it should pay attention to the recessive educational form,establish a perfect evaluation mechanism,attaches great importance to the subjectivity of entity class teaching and the combination of Internet in the process,and explore the Internet plus mode of medical professionalism education together.

Objective To analyze the clinical value of microRNAs applied in the early diagnosis of pancreatic cancer.Methods The expression of mir-155,mir-196a,mir-181a,mir-181b in three pancreatic cancer cell lines PANC-1,PaCa-2,AsPC-1 pancreatic cancer,normal pancreatic cells and plasmas of 100 patients with pancreatic cancer ,100 normal volunteers were detected by Real-time PCR,and the results were analyzed.The expression of mir-155,mir-196a,mir-181a,mir-181b in 100 pancreatic cancer tissues and 100 normal pancreatic tissues were detected by immunohistochemical,and the results were analyzed. Results Real-timePCR test results showed that compared with normal pancreatic cells,mir-155,mir-196a expression in three pancreatic cancer cells PANC-1,PaCa-2,AsPC-1 were significantly increased(P<0.05).Compared with healthy volunteers,mir-155,mir-196a,mir-181a,mir-181b expression of plasma in pancreatic cancer patients were significantly higher(P<0.05).Immunohistochemistry results showed that mir-155,mir-196a mir-181a and mir-181b expression in pancreatic tissue were significantly higher than that in normal pancreatic tissue (P <0.05 ).Conclusion The expression of mir-155,mir-196a,mir-181a and mir-181b are high in pancreatic cancer tissues and pancreatic cancer cell lines,which are closely related to the development of pancreatic cancer.Those microRNAs are expected to be cancer markers for early diagnosis of,pancreatic cancer,have highly diagnostic value and broad clinical application.

A novel approach of vaccination against cancer is to exploit dendritic cells (DC) as the best antigen presenting cells (APC) and actively immunize cancer patients with a sample of autologous or allogeneic DC primed with tumor antigens. DC vaccination is still at its early stage, however, valuable proofs of concept have been obtained with respect to the capacity of DC to expand cancer directed immune responses. The methods for preparing DC are being improved continuously, and there are many opportunities to improve efficacy at the level of DC biology. An increased number of clinical studies will drive the development of this new area. This paper reviews the production of dendritic cell tumor vaccines and their use in clinical trials, as well as emphasizes some unresolved questions in this immunotherapy.

Objective To select a matrix modifier,which can effectively eliminate the matrix interference in the determination of chromium in cosmetics by graphite furnace atomic absorption spectrometry(GFAAS).Methods The orthogonal experiment design was used to define the best operation parameter of graphite furnace.Vitamin C,(NH4)H2PO4,(NH4)2HPO4,NH4Cl and Mg(NO3)2 were added respectively as the matrix modifiers.The effect of five matrix modifiers was compared by precision test.Results When(NH4)H2PO4 was taken as the chemical modifier,the determination result was satisfied.The characteristic mass was 5.68?10-12 g,relative standard deviation were from 2.11% to 4.46%.The rate of recovery of two cosmetics samples were 95.2% and 102.01%.Conclusion(NH4)H2PO4 can increase the ashing temperature,decrease the atomization temperature,eliminate the matrix interference and the result has good precision and accuracy.

ObjectiveTo evaluate the correlation between ultrasound detected fetal heart abnormality and chromosomal abnormality.Methods The data of 3307 cases of prenatal fetal echocardiography and karyotype analysis results were retrospectively analyzed.The correlation between heart abnormality and chromsomal abnormality was analyzed.ResultsIn 3307 cases d pregnant women,194cases (5.87％) were found signs of fetal heart abnormality,and 3113 cases (94.13％) were not found any sign of fetal heart abnormality.And 124 cases(3.75％) were found chromosomal abnormality.The rate of chromosomal abnormality in fetus with heart abnormality was higher than that in fetus without heart abnormality[ 19.59％ (38/194) vs.2.76％ ( 86/3113 ),P ＜ 0.01 ],the relative risk ratio was 7.0903.One hundred and twenty-four cases of chromosomal abnormality in the 18-three-body(42 cases) and 21-three-body(36 cases) were the most common.ConclusionsFetal heart abnormality incidence of chromosomal abnormality is high relatively.When the signs of heart abnormality are found,it is suggested that the fetus should examine karyotype analysis.

Objective To investigate the expression and significance of intermedin (IMD) and its.receptors CRLR,RAMP1,RAMP2 and RAMP3 in cancer tissues of patients with non-small cell lung cancer.Methods The mRNA gene expressions of IMD,CRLR,RAMP1,RAMP2 and RAMP3 were detected by realtime quantitative RT-PCR in cancerous and para-cancerous tissues from 27 patients with lung cancer.Results Real-time quantitative PCR detection results showed that the expression of IMD,CRLR,RAMP1,RAMP2 and RAMP3 in cancer tissues were [(59±7.9)×10-8,(96±2.7)×10-6,(29±3.9)×10-9,(14±2.6)×10-6,(65±1.1)×10-6]which were higher than those in adjacent tissues[(40±4.7)×10-10,(21 ±3.9)×10-6,(53±7.8)×10-10,(64±1.9)×10-8,(36±1.3)×10-9] to some extent (all P ＜ 0.05); the higher expression of RAMP3 was found is higher expressions than RAMP1 and RAMP2 in cancer tissues (all P ＜ 0.05).Conclusion The expressions of IMD and its receptors in cancer tissues are higher than those in paracancerous tissues.IMD may play an important role in the development of cancer by activate RAMP3 which is the most high expressed receptor in cancer tissues.Therefore,it might be helpful for the investigation of new gene thereapy in non-small cell lung cancer.
