The key point to define the psychological problem in children is the grasp of degree,also,the key point to educate children is the grasp of degree.Are there some principles to clarify the degree? How to quantify the degree? This paper brought forward the gold zone method of psychological guidance in children and adolescents and defined its quantitive expression as golden section.The gold zone method can grasp the scale set according to the goal,form the proper consumption value,control the interpersonal intimacy,cultivate fine thinking and behavioral pattern,and give appropriate guidance to many basic problems about children's growth.

In 21st century, clinical medicine moves toward a model of individualized health care. The development of the individualized model is based on the research findings of human genomics project including genotype and single nucleotide polymorphisms (SNPs), as well as the new health care model, that is, biological-psychological-social-environmental-spiritual. It reflects the idea of patient-centered care, and corresponds to the traditional practice of Chinese medicine, which addressed the individualized therapy on the basis of symptom pattern differentiation. However, the era of evidence-based medicine affords new meanings of individualized health care and promotes the research on the practice. The practice based on evidence would happen upon the integration of external research evidence, the expertise and experience of practitioners, and the value and preference of patients, so the decision of health care will be conscientious, explicit and judicious. This assay describes the meanings of individualized health care in different medical contexts, the characteristics of individualized practice in Chinese medicine, and proposals for further research in practice.

Cohort study is graded as level II in evidence grading system of evidence-based medicine, secondary to randomized controlled trial. It is one of the important evidence for the evaluation of health care interventions, and it has been applied recently in the evaluation of traditional medicine. The author of the article introduces the basic concept, principle, design, and implementation as well as relevant methodological issues when applied in traditional Chinese medicine.

The quality of clinical trials in traditional Chinese medicine (TCM) was analyzed with respect to their methodology and outcome assessment according to the concepts of evidence-based medicine (EBM). It was suggested that the essential methodological principles of EBM should be applied in clinical trials of TCM, including randomization, control and blindness. The sample size estimation, optimal parameter selection for outcome assessment, compliance and intention-to-treat analysis are all important aspects of randomized controlled trials. To bring the benefits of EBM into clinical trials will improve the quality of research in TCM and also promote international co-operation and communications. It is necessary to establish an assessment system of clinical outcome for TCM on the basis of EBM in order to evaluate the efficacy and safety of TCM objectively and scientifically.

Plasma fibronectin (PFn) was determined serially by both simple radial immunodiffusion (RID) and improved indirect hemoagglutination test (using gelatin-coated sheep RBC) in the serum of 30 patients with severe viral hepatitis (SVH),100 normal subjects,and 30 patients with chronic active hepatitis (CAH).Liver function,serum C3 and immunoglobulin (Ig) were determined simultaneously.Endotoxin was assayed by Limulus lysate test in 21 patients with SVH.The normal value of PFn was 284.31?45.56?g/ml and 1:30.64 (geometrical mean).The PFn level significantly decreased in patients with SVH.Significant correlations were found between PFn levels and the values of total serum bilirubin,prothrombin time,C3 and IgM.Low PFn levels were remarkably associated with the occurrence of endotoxeamia.Serial determinations of PFn in serum can reflect the severity of the illness and prognosis in the patients with SVH.

Evidence-based medicine (EBM) has rapidly developed in recent years and is currently a hotspot in international medicine. The guiding principle behind EBM is that any medical decision should be determined based on objective clinical and scientific evidence, doctor's professional skills and experience, and patient's needs and desires. This paper introduces the concept and practice of EBM and explains how it can be used to solve the issues in stomatology.

Objective Inaccurate dosing is an important cause of medical malpractice, how to adjust the medication dose to overcome the excessive deviation will be discussed in this paper. Methods Gold zone method was proposed on the basis of the probability theory and mathematical statistics for handling inaccurate dosing problems. Investigation and study in large sample size was carried out on adverse reactions of Cefamandole Nafate for Injection by adopting the method. Results The conclusions from the super large sample size test indicate that there is highly significant difference of total adverse reaction rates between taking values within and outside golden zone of dosage, and the adverse reaction rate of taking values within golden zone is significantly lower than that of outside golden zone. It is noteworthy that when dosage was lower than golden zone,the adverse reaction rate was significantly increased,which is more than 4 times of that within golden zone. Conclusion It is effective measures and simply and easy to apply that taking values within golden zone of dosage reduce adverse drug reactions,probability within golden zone less than 1/4 range of experience that contains the actual demand of the body up to 70%.

A systematic review is based on randomized controlled trials (RCTs), and the reliability of its conclusion is closely related to the quality of original literature. The low quality of existing RCTs in China leads to the failure of conclusive findings in systematic reviews when evaluating the effectiveness of interventions. It is almost universal for systematic reviews to draw the conclusion that "further well-designed multicenter and large-scale RCTs are still required to confirm the beneficial effects of interventions". This paper analyzed the current status of RCTs in China, discussed the influence of including trials of low quality in a systematic review and assessed how a systematic review should be carried out under such circumstances. Furthermore, the methods to evaluate the quality of RCTs were introduced and evaluated. Finally, several strategies were proposed to improve the quality of RCTs in China: foster an honest academic and social environment, enhance the training of doctors on clinical research methodology, promote the implementation of clinical registration systems and strengthen the quality control of clinical research and the medical journals regulations on the quality of submitted papers.

ObjectiveTo explore the effects of personality characteristics and mental health of students on the career orientation.MethodsThe method of stratified random sampling was used in three universities of Jiangxi province.501 subjects of Arts,Science and Medical Science were tested with Holland career orientation test,symptom check list(SCL-90) and 16 personality factors(16PF).Structure validity analysis,analysis of variance and t -value test were employed with LISREL8.70 and SPSS13.0.Results ( 1 ) The proportion of students choosed the type of occupation were:social type 36％,management type 18％,conventional type 17％,reality type 14％,investigation type 9％,artistic type 6％ ; (2) Career orientation,personality characteristics and mental health had moderate effect on the career orientation.The correlation coefficients of personality characteristics and mental health to the vocational orientation were 0.63 and 0.44.The interaction correlation coefficient was 0.56.ConclusionPersonality characteristics and mental health of college students are important factors to the career orientation and decision-making of job seeking.The personality has stronger explanatory power than mental health.Great emphasis should be paid on both short-term psychological health of college students and long-term cultivation of healthy personality in the employment psychological guidance.
