Some prominent problems existed. This article also proposed some practical suggestions to solve the problems based on the analysis of this phenomenon, so as to improve the humanities education of medical postgraduates and cultivate postgraduates to be medical workers with full humanistic care.

Objective To examine the relative effectiveness of extracorporeal shock wave therapy (ESWT) and ultrasound therapy (US) on managing heel pain. Methods Thirty seven patients were divided into 3 groups, two treatment groups (groups 1 and 2) and one control group (group 3).Group 1 received ESWT once a week for 3 consecutive weeks.Parameters were set at a frequency of 4Hz with a total of 1000 impulses, intensity at 0.23 to 0.37mJ/mm 2. Group 2 received continuous ultrasound therapy for 5 minutes in each session, three times a week for three consecutive weeks. Parameters were set at 1MHz, intensity level at 1W/mm 2. Group 3 was the control group and no treatment was given during the study period.The intensity of morning pain on weight bearing, pain triggered by prolonged walking/standing, pain on tension and palpation tests were assessed by use of Visual Analogue Scale (VAS) before and after each treatment session, including the follow up session.In addition, Mayo Clinical Scoring System (MCSS) was used to evaluate the treatment outcomes. Results After 3 weeks of treatment plus 3 weeks follow up,outcome measures had shown statistical significant difference on the intensity of pain on tension test( P =0.037),the intensity of pain on palpation test ( P =0.019) and the maximum duration of prolonged walking or standing ( P =0.002). Conclusion ESWT is more effective and efficient for managing heel pain than ultrasound therapy.

Objective:To establish a method to determine the residual solvents in salvianolic acid B. Methods: The headspace GC was carried out on an HP-5 capillary column(30 m × 0. 32 mm,0. 6 μm). The inlet temperature was 180℃. The injection volume was 0. 1ml and the separation ratio was 1:10. The column temperature was programmed:the initial temperature was 40℃, malntalned for 6 min, ralsed to 180℃ with a rate of 15 ℃·min-1 , and malntalned for another 5 min. The detector was FID with the temperature of 250℃. The carrier gas was N2 with the flow rate of 1. 7 ml·min-1 . DMSO was used as the solvent for salvianolic acid B. Results:All solvents could be separated completely. The linear range of ethanol, acetone and ethyl acetate was 12. 650-1. 012 × 103 μg·ml-1 (r=0.999 3),12.750-1.012 ×103 μg·ml-1(r=0.999 7) and 12.550-1.004 ×103 μg·ml-1(r=0.999 7), respectively. The average recovery of ethanol, acetone and ethyl acetate was 96. 89% (RSD=3. 81%,n=9), 99. 56% (RSD=4. 05%,n=9) and 97. 21% (RSD=4. 95%,n=9), respectively. Conclusion:The method is simple, reproducible and accurate enough for the determi-nation of residual solvents in salvianolic acid B.

Objective To evaluate the academic level and the popularity of Chinese Journal of Hepatobiliary Surgery.Method According to the information of Chinese Medical Citation Index(CMCI),I statistically analyzed the amount and distribution of the originals in Chinese Journal of Hepatobiliary Surgery cited by the journal included by CMCI.Result The average of original articles cited by other researchers is 2.93,and there are more articles cited than other journal.The authors of these articles are from the 30 province,Beijing Shanghai and Guangdong Province are in the front of Hepatobiliary Surgery research.There are 355 citing journals,and self-citing rate is 11.89%.Conclusion With the unique style and character Chinese Journal of Hepatobiliary Surgery is the main medical core periodical and one of the most important information resourses in the field of Medical Hepatobiliary Surgery in China.

Objective To investigate the correlation between abnormal lipid metabolism and coronary artery lesions. Methods Two hundred and sixty seven patients were devided into the control group ( n =101) and the coronary heart disease (CHD) group ( n =166), which included single vessel lesion ( n =54), double vessel lesions ( n =68) and triple vessel lesions ( n =44) according to coronary angiography. At the same time the lipid components were examined and the ralationship between serum lipid level and coronary artery lesions were analysed. Results Compared with the control, the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triglyceride (TG) level were significantly elevated while but high density lipoprotein cholesterol (HDL-C) was lowered in the CHD group. The severity of coronary lesions was increased with the elevation of TC, LDL-C, apolipoproteinB (ApoB), TC/HDL-C, LDL-C/HDL-C, and the reduction of HDL-C. There were significant differences in terms of lipid level beteewn the CHD group and the control. The analysis showed that TC/HDL-C and LDL-C/HDL-C were most directly correlated with the coronary artery lesions in the CHD group. Conclusion The results suggest that the severity of coronary artery lesions correlated with abnormal lipid metabolism, and LDL-C/HDL-C, TC/HDL-C are better indicators than other lipid components.

The defense mechinism of heat shock protein(HSP)acting as moleculars chaperons requires heat shock transcription factors as the primary mediators of the heat shock response.Increased expression of HSP may protect the heart.Overexpression of HSP can inhibit cardiomyocyte apoptosis,protect the integrity of the microtubules and the actin cytoskeleton in cardiac myocytes and endothelial cells exposed to ischemia,participate in the folding and activation of protein kinases and transcription factors such as HIF-1? and HSF1,bind to endothelial nitric oxide synthase(Enos) and stimulate its activity,and downregulate cytokine production.Hence,it is of benefit to efficiently elevate HSP expression in myocardium using pharmacological and/or gene therapy procedures without any adverse effect.

Objective To evaluate the academic quality and characteristics of edition of the Chinese Journal of Geriatrics. Methods Within the database of Chinese Medical Citation Index(CMCI), the citation analysis was used to analyze the number and its distribution of the cited original articles published in the Journal 1999-2004. Results The average freguency for a single article cited by other researchers was 2.82, and there were more articles cited than other journals. The authors of these articles were distributed in the 30 province and municipalities, among which Beijing, Guangdong Province, Shanghai were in the front of Geriatrics research. There were 514 cited journals, and self-citing rate was 6.07%. Conclusions The Chinese Journal of Geriatrics has published high quality articles, and has its own edition characteristics to keep its steady level of research. It is one of the most important information resources for the geriatrics researchers and one of the most important medical journal.

A total of 21 papers about topical use of triamcinolone in the treatment of oral diseases were retrieved.1 7 of the 21 papers were about the treatment of oral lichen planus,3 were about recurrent aphthous ulcer and 1 was about Behcet's Syndrome.Topical use of triamcin-olone,either used alone or combined with other drugs,was effective in the treatment of oral lichen planus,recurrent aphthous ulcer and Beh-cet's Syndrome.No adverse drug reaction happened when triamcinolone was used in the patients after a short time application,while it hap-pened in the patients after prolonged-use.It may be also effective in the treatment of other allergy or immune dysfunction related oral mucosal diseases,of which more research should be carried out.
