Objective:To study the cause of clinical and pathological misdiagnosis and the measures against misdiagnosis in cases with primary non-Hodgkin's lymphoma in Waldeyer's ring.Methods:The clincal data of ninty two patients with primary NHL in Waldeyer's ring admitted to our hospital in recent ten years were studied retrospectively.Results:Eighteen patients were misdiagnosed clinically and seventy two patients were misdiagnosed pathologically.18 cases were misdiagnosed both clinically and pathologically, with the average misdiagnosis rate of 2～3 times per case.The misdiagnosed diseases were chronic tonsillitis,tonsil vegetation,pharyngitis,lymphatic tissue hyperplasia,etc.All seventy-two patients were diagnosed as NHL finally.Conclusion:The patients with the primary NHL in Waldeyer's ring lack characterisic symptoms.Pathological manifestation is complicated.It is important to do biopsy exactly and diagnose early by immunohistochemical approaches.

Objective:To analyze and conclude the common causes and clinical features of hoarseness in patients at different ages.Methods:The data of 1100 cases of hoarseness in diferent ages were analyzed with laryngofiberscopy.Results:The main 5 causes of hoarseness were neoplasm(767cases,69.72%),laryngitis(188cases 17.09%),paralysis of vocal cord(75cases,6.82%),trauma(30cases,2.73%),and others(40cases,3.63%).The number of its distribution in 4 age groups was different(P

Objective:To study the differential expression proteins of laryngeal squamous cell carcinoma tissue and paired normal tumor adjacent mucosa epithelia tissue.Methods:The total proteins of laryngeal cancer tissue and paired normal tumor-adjacent mucosa epithelial tissue were separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis(2-DE).Coomassie brilliant blue dyeing.The differential expression proteins were analyzed by using ImageMaster 2D analysis software. Then identified by peptide mass fingerprint(PMF)based on matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS)and database searching. Result:We obtained well-resolved,reproducible 2-DE patterns of laryngeal cancer and normal mucosa epithelia1.Differential protein spots were defined as spots in 2-DE gels.33 proteins were preliminarily identified,among which 22proteins were upregulated in laryngeal cancer tissue,while 11 were decreased significantly. PMF maps of 10 proteins which were upregulated in laryngeal cancer tissue were obtained by MALDI-TOF-MS. The typic peptide masses were searched in the Mascot database. Eight proteins were preliminanily identified.Conclusion:We established the expression maps of proteomics in laryngeal cancer and normal mucosa epithelia1.There were significant differences among proteome of laryngeal cancer and normal mucosa epithelia1.These proteins may be potential diagnostic markers and therapeutic targets for laryngeal cancer.And is valuable for studying mechanisms of laryngeal carcinogenesis.

This article analyzes the prominent features of the advanced nursing education in America from four aspects:prospects of the nursing education,requirements for the undergradua te nursing majors,network education and postgraduate education,and proposes some suggestions of developing the advanced nursing education in China,in combination with the present situation of cultivating senior nurses in our country.

Based on the present situation analysis of nursing experimental teaching for undergraduate,reform was carried out through our innovating experimental teaching philosophy,integrating experimental teaching curriculum,compiling experimental teaching materials,establishing experimental teaching inspection and assessment system and consummating management mechanism of experimental teaching center,and some developing thoughts were also proposed.

Objective To explore the reason and influence of communication difficulties between oncology nurses and patients or families of patients,and to obtain some relevant advice about communication difficulties.Methods This study used focus group to interview 24 oncology nurses who were selected from the First Affiliated Hospital of Chongqing Medical University by homogeneous sampling method,and were randomly divided into three groups (8 in each group).The data were processed and analyzed by content analysis.Results The reasons why oncology nurses had communication difficulties with patients and their families were as follows:putting forward negative problems about their disease,ineffective communication and conflicts with patients,families.The communication difficulties showed negative effect on oncology nurses.Oncology nurses thought that the main reason of communication difficulties lied in the deficiency of institution and propounded the suggestion to resolve it.Conclusions oncology nurses were tend to have difficulty in communicating with patients and their families in the long-term work,especially in the period of crisis:early diagnosis of tumor stage,relapse,advanced cancer and some special dates (birthday,parties etc.).Therefore,oncology nurses,patients and their families need to be supported.To solve the difficulties of communication could reduce the negative emotions of patients and their family,such as anxiety,frustration,helplessness,so as to improve the quality of care and life of patients.

This article systematically introduced the development of Smart Healthcare mode in Hangzhou. From the aspects of connotation, pattern, characteristics and the change of medical treatment mode, the authors pointed out that the development of Smart Healthcare must follow such principles as satisfaction of the people, enhanced inter-departmental synergy, government-guided social participation, and full involvement of medical workers.

Objective To investigate the association between the three single nucleotide polymorphisms (SNP) in angiotensin Ⅱ type one receptor (AT1R) gene with coronary artery disease (CAD) in Chinese Han nationality.Methods Extracted DNA and RNA samples of peripheral blood white cells from 192 CAD patients and 189 healthy individuals in Jan 2011 to Oct 2013 from the general hospital of the PLA Rocket Force.Designed primes and the three SNPs as rs6801836,rs2675511 and rs5182 of AT1R gene were analyzed with allele-specific fluorogenic oligonucleotide probes in an assay combining extension and hybridization.Results The genotype and allele frequencies of the three SNPs were not significantly different between the control group and CAD group (x2 =0.047～2.226,all P＞0.05).The major haplotype constructed with linkaged rs6801836 and rs5182 was TT.The frequency of every haplotypes showed no significantly difference between the two groups (x2 =0.025～1.020,all P＞0.05).Conclusion The three polymorphisms of AT1R gene studied in this work showed no association with CAD susceptibility.

Objective To establish two-dimensional electrophoresis profiles of laryngeal squamous carcinoma tissue with high resolution and reproducibility. Methods The total protein of well-differentiated or poorly-differentiated laryngeal cancer tissue was separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). The differential expression protein was analyzed by using ImageMaster 2D analysis software. Results We obtained fine resolution, reproducible 2-DE patterns of well-differentiated and poorly-differentiated laryngeal squamous carcinoma. Differential expression protein spots were defined in 2-DE gels. Thirteen protein spots were preliminarily identified, among which seven proteins were upregulated in well-differentiated laryngeal cancer tissue, six were downregulated. Conclusion The expression map of proteomics was established for well-differentiated and poorly-differentiated laryngeal cancer, which was of significant difference between them. Laryngeal cancer proteome might reflect the underlying pathological state.

With the internationalization of nursing education,one major project facing higher nursing education is to foster lots of high quality nursing specialists,with properties of international vision,development prospect,and adaptation to international nursing positions.Chongqing Medical University engaged in reforming and implementation of talents culturing and yielded significant effect along with the main competency ideology of humanistic caring,critical thinking,evidence-based nursing,practicing and international competition.
