With the development of perinatal medicine,the survival rate of preterm infants has risen these years,and the incidence of bronchopulmonary dysplasia (BPD) has also increased as a result.BPD is a chronic lung disease which is caused by multiple factors,It has complicated etiology and pathogenesis,high mortality early after birth,and high incidence of later adverse outcomes in respiratory and nervous systems,which seriously affect the survival rate and quality of life in preterm infants.This article will summarize the current situation in prevention and treatment of BPD.

Sepsis is one of the most important causes of death in critically ill children.The leading cause of sepsis is bacterial infection.The early diagnosis of bacterial infection allows initiation of appropriate antimicrobial therapy that strongly correlates with positive outcomes.At present,the methods of detection and identification of bacteria in our country are still at the level of blood culture and biochemistry,and they have the weakness of time-consuming process and lower positive rate.Therefore,it is very important to establish a rapid and sensitive diagnostic method for early diagnosis of bacterial infection.In recent years,with the rapid development of molecular detection technology,some new molecular biological technologies can not only improve the detection accuracy and sensitivity,but also reduce the detection hours and expand the detection pathogen spectrum.Nowadays,they have been applied to bacteria classification and identification.There are two kinds of molecular biological technology that are applied at present.One is based on nucleic acid detective technology,such as nucleic acid amplification,DNA sequencing,gene chips,etc.The other is based on proteome technologies,such as biological mass spectrometry.In this paper,the application of recent molecular biological techniques in the rapid detection of bacteria is reviewed.

Intestinal trefoil factor(ITF)is a low molecular weight polypeptide expressed in intestine. ITF is also found in the brain,respiratory,eyes and so on.To study recombinant ITF will have an important impact for the treatment of gastrointestinal disease, respiratory tract disease, eyes disease and so on.

Aimed at problems in current audio-visual-oral English teaching for medical students,such as the inconsistency between teaching materials and training objectives,the lack of flexibility and effectiveness in teaching methods and inadequacy of comprehensiveness and objectiveness in assessment methods,the paper analyses and explores audio-visual-oral medical English teaching in three aspects,namely teaching curriculum-setting up topic for each unit based on the contents of medical courses and designing various teaching tasks according to three-step procedure of extensive listening-intensive listening-derivative discussion,teaching methods-adopting pictorial method in teaching medical English vocabulary,macro-micro listening method and interpretation for imitation method,and assessment methods-applying a combination of formative assessment and summative assessment.

In view of the present situation of medical English vocabulary teaching, we propose to apply the picture teaching method to the teaching of English vocabulary. Picture application process is:teaching ideas - picture searching - picture introduction - question design - example sentence (implica-tions) introduction. We also analyze how to apply pictures related to Chinese and western culture, anecdotes and oddities, stars and celebrities, and common diseases to medical English vocabulary teaching according to the features and interest of the students, so as to activate the knowledge the students already acquired, to achieve good teaching effect through interaction between the teacher and students and to help the students have a solid command of medical English vocabulary taught in class.

BACKGROUND:Discogenic pain is a major cause of chronic low back pain,and its inflammation mechanism that is participated by many cytokines is well known by more and more people. However,what is the role of these cytokines in the occurrence and development of pain and how we use them to control pain are still not consistent. OBJECTIVE:To completely learn about the pathogenesis of intervertebral disk herniation,the relative cytokines in the occurrence and development of pain and the advances in the treatment of chronic pain with cytokines. RETRIEVE STRATEGY:A computer-based online search of CNKD was undertaken to identify the relevant articles dated from January 1994 to June 2007 with the Chinese of "cytokine,pain". And totally 153 articles were collected. Meanwhile,PubMed database was searched for English articles published from January 2002 to June 2007 with the keywords of "gene,chronic pain" and 36 were collected. The articles that involved the basic and clinical researches closely related with cytokine were selected. Repetitive articles were excluded. After the trail,6 Chinese and 24 English articles were involved. LITERATURE EVALUATION:Of the 30 articles,10 were focused on the basic research and animal experiment,and 20 were about clinical research. There were 7 of RCT,1 of EBM review,10 of summary analysis,2 of case report,and 10 of experience exchange. DATA SYNTHESIS:The mechanisms of discogenic pain include inflammation and immune ones besides mechanical pressure. Inflammation mechanism of discogenic pain is well known by more and more people,in which many cytokines such as substance P,phospholipase A2,tumor necrosis factor,interleukin,growth factor and NO participate. Meanwhile,the role of immunities should not be ignored. Some researchers have used some cytokines(interleukin 1 receptor antagonist,vascular endothelial growth factor,etc) in clinic to treat pains and got good effect. CONCLUSION:The mechanism of pain and various effects of pain-killer are based on gene. Cytokines play important roles in the occurrence,development and treatment of discogenic pain.

Objective To observe the therapeutic effects of comprehensive rehabilitation treatment in patients with chronic renal failure (CRF). Methods Fifty patients with CRF were randomly and equally divided into a rehabilitation group and a control group. Those in the rehabilitation group were intervened with comprehensive rehabilitation protocol including regular counseling, health education and adequate aerobic exercise in addition to routine medications, while those in the control group with the routine medications only. The therapeutic effects were evaluated by means of Symptom Check List- 90(SCL- 90) and the questionnaire about quality of life (QOL) for patients with CRF, as well as such biochemical parameters as SCr, BUN, Ccr, DBP and SBP before and after treatment. Results Compared with those in the control group, the physiological capability and other relevant parameters of QOL in the rehabilitation group were significantly improved after one year of comprehensive rehabilitation, while SBP and DBP significantly decreased. There was no statistically significant changes of the concentrations of Scr, Bun, and Ccr. Conclusion Comprehensive rehabilitation intervention is superior to routine drug therapy in terms of improving the physiological capability, decreasing the BP and improving the QOL of the CRF patients.
