There was the theory that all the disorders of the ve zang-organs can cause cough originated from Inner Canon of Huangdi.Many famous experts in ancient times developed the theory,which is important in guiding the clinical practice.Professor LIAN always treats cough,especially chronic cough from regulating qi activity of five zang-organs.For example,Xiaoyao powder for cough due to liver disorder,Fumai decoction for cough due to heart disorder,and so on.The curative e ect is remarkable because the treatment is based on origin of disease.This article adopts and analyze some proved cases of ve zang-organs,which is helpful in inheriting and developing ancient theory.

Objective To construct the evaluation index system of medical education for clinical departments in grade-three hospitals.Methods Questionnaire were answered by the clinical experts,medical education directors and VP for education in the grade-three hospitals.According to the principle of Delphi method,the survey included the basic situation of experts,the relative importance of each index and the degree of expert authority.SPSS 16.0 was used to analyze the data.Results The questionnaire recovery rate was 90％,with authority of the average value 0.88,and coordination coefficient 0.348.The coordination coefficient was tested by chi square test,P=0.000.Five first level indexes by the authoritative coefficient after correction (residency training,postgraduate education,academic education,continuing medical education,teaching for refresher doctors) of the weighted value (％) were 22、22、22、19 and 15 respectively.Conclusion The experts in this study represent strong and high enthusiasm and authority.After practical application,the index system is supposed to have practical application value.

Objective: To test the reliability and validity of a questionnaire on knowledge, beliefs and intentions about AIDS/safe sex for university students. Methods: Based on the data investigated with this questionnaire from 598 university students and the test-retest data from 63 university students, the internal consistency, test-retest reliability and construct validity were calculated. Results: This questionnaire had good reliability, with most parts having Cronbach ? coefficients large than 0.7 and retest coefficients large than 0.6. The factor structure was consistent with the theoretical hypothesis and the factors could explain 58.85% of the whole questionnaire.Conclusion:This questionnaire can be applied among university students to assess AIDS/safer sex related knowledge, beliefs and behavioral intentions.

Objective To explore the clinical effect of microendoscopic discectomy through posterior approach in old patients with multilevel lumber spinal stenosis and analyze the influence factors that related to clinical effect .Methods 64 old patients with multilevel lumber spinal stenosis were selected and divided into microendoscopic group and open group based on different operation method ,each group contained 32 patients .Comparison was made between two groups in respects of operation time ,amount of bleed-ing ,hospital time post-operation and Nakai scores .Analyzed the influence factors that related to clinical effect .Results The opera-tion time ,amount of bleeding ,hospital time post-operation in microendoscopic group were lower than open group ,the differences had statistical significance .Based on the Nakei score ,the curative effect in microendoscopic group was slightly lower than open group ,but the differences had no statistical significance .The JOA score pre-operation ,walking distances and complication were rela-tive factors that could influence the clinical effect of microendoscopic discectomy through posterior approach method .Conclusion Microendoscopic discectomy through posterior approach in old patients with multilevel lumber spinal stenosis had quicker postoper-ative recovery than conventional operation ,and the JOA score pre-operation ,walking distances and complication were relative fac-tors that could influence the clinical effect of microendoscopic discectomy through posterior approach method .

Objective:To evaluate the potential value of indocyanine green combined with methylene blue and methylene blue alone in the detection of sentinel lymph nodes (SLN) in breast cancer.Methods:The clinical data of 118 patients with early breast cancer from November 2016 to October 2018 in Dalian Central Hospital Affiliated to Dalian Medical University were retrospectively analyzed. Among them, 62 patients underwent SLN biopsy under methylene blue (methylene blue group, 160 SLN), and 56 patients underwent SLN biopsy under indocyanine green combined with methylene blue (combined group, 190 SLN). After SLN biopsy, patients underwent grade Ⅰ and Ⅱ axillary lymph node dissection.Results:There was no significant difference in the positive lymph node rate and accuracy rate between 2 groups ( P>0.05); the SLN dyeing rate and SLN biopsy positive rate in combined group were significantly higher than those in methylene blue group: 97.9% (186/190) vs. 93.1% (149/160) and 28.4% (54/190) vs. 18.1% (29/160), and there were statistical differences ( P<0.05); the false negative rate in combined group was lower than that in methylene blue group: 5.3% (3/57) vs. 14.7% (5/34), but there was no statistical difference ( P>0.05). Conclusions:In breast cancer patients, the dual -tracing method of indocyanine green combined with methylene blue is better than using methylene blue alone in identifying SLN and predicting the status of axillary lymph nodes, and it has a tendency to reduce the false negative rate.

Objective To observe the intervention of acupuncture on guinea pig models of allergic reaction type Ⅳ.Methods Thirty-six albino guinea pigs were randomized into blank control group,model group,and acupuncture group.The guinea pig models of allergic reaction type Ⅳ were established by external application of dinitrochlorobenzene.The acupuncture group received acupuncture on acupoints of Quchi and Xuehai for 10 days.After treatment,the auricular thickness and weight,the number of intradermal inflammatory cells,and the auricular pathological changes in guinea pigs were observed.Results In the model group,the auricular thickness and weight were increased,and the number of intradermal monocytes,lymphocytes,neutrophils,and fibrocytes was also increased(P0.05),and the pathological changes of chronic eczema were relieved.Conclusion Acupuncture exerts an intervention on allergic reaction type Ⅳ.

By software and signal analysis,visualization of medical NMR signals becomes possible.The T1,T2 resonance frequency value reflecting human tissue characteristics,and the FID,echo wave as well as other curves reflecting the intensity of signals,can contribute a lot to the teaching of the applied analysis of clinical NMR and MRI principles.

Objective:To explore the relationship between lifestyle,self-esteem and life satisfaction among Chinese adolescents.Methods:10 899 adolescents in middle schools and colleges from 9 provinces in China were investigated by using Chinese Adolescent Lifestyle Scale(CALS),Rosenberg Self-Esteem Scale(SES).Results:The distribution of adolescents in the four groups divided by lifestyle and life satisfaction scores were different regarding the area and grade of these students(?2=248.93,P

Defensin is a kind of antimicrobiol and cytotoxic peptides which have been found in a large range of living organisms. The mammal defensins have the most wide range antimicrobiol spectrum. The distribution, structure, gene expression regulation of mammal defensins in China and abroad were summarized. Its application on medicine and plant resistant gene engineering were prospected.
