Study on Rank—Frequency Distribution of Scientific Research Papers by Chinese University famous teacher teaching in biomedicine domain from 2003 to 2009.Whose quantitative indicators of scientific papers were negative logarithmic distribution,except provincial-level teaching famous teachers' SCI papers were negative exponential distribution. The qualitative index were negative logarithmic,except state-level teaching famous teachers' SCI paper yearly average paper cited were linear distribution and provincial-level were negative exponent distribution.The magnitude of concentrations was between 0.257 and 0.728,which deviates from the Price's law (0.50). It indicates that the Rank-frequency distribution model can be applied to the teaching famous teacher.The internal gradation instrument in the top scientists is different from in science community.Scientist's gradation in the science community depends on whether the objective of scientific paper evaluation comes true.The state-level teaching famous teacher scientific paper difference is greater than the provincial-level; SCI paper difference is bigger than the CSCD paper.

This study analyzed the average annual growth rate of Youth Science Fund projects and the National Science Fund for Distinguished Young Scholar in 11 colleges and universities.Those projects were funded by the department of life science of National Natural Science Foundation of China (NSFC) in 2001- 2009.The average annual growth rate was calculated by Algebraic average method.The results showed that:① the average annual growth rate of Youth Science Fund project rose or dropped with the rise or drop of average annual growth rate of Science Fund Project.② the rapid growth of Youth Science Fund projects may enhance the ability of colleges and universities to gain National Science Fund for Distinguished Young Scholar.③ the capability of colleges and universities to gain life science project funded by NSFC is not balanced among different regions,and this gap is widening,and ④ to narrow the gap between disciplines,greater effort is needed to train outstanding young scholars.

Objective To discuss the effects of health management model on mental health of undergraduates. Methods A total of 2244 freshmen from a college were randomly assigned to the study group (n =824) and the control group (n = 1420) in 2009. Chinese College Students Mental Health Scale (CCSMHS) was used to investigate the changes of the participants in the study group after receiving the health management and analyze psychological differences between 2 groups. Results In CCSMHS,all P was found to be less than 0. 05, except for anxiety ( t = 1.90, P = 0. 058 ), reliance ( t = 1.27, P = 0. 206), and impulse (t = -0. 60, P = 0. 551 ). In 8 dimensionalities with significant differences, scores were decreased after health management when compared with baselines. Instead of body ( t = - 1.38, P = 0. 168 ), all the other scores showed statistically significant differences between the 2 groups. Conclusion Mental health of those who received health management was better than those who didn't. However, anxiety, reliant, and impulse did not improve as a result of shorter intervention time, and the challenge facing psychology intervenion.

Objective To learn research cooperation and evolution process in the field of health management in China so as to provide evidence for decision-making.Methods A total of 2180 literatures were selected to investigate author affiliation,high output author,research cooperation,high frequency keywords,and research hotspot through information visualization tool CiteSpace Ⅱ.Results Domestic health management research literature had showed an increasing trend since 2007 and leveled off during recent 3 years (average annual output 446.7).A total of 4 216 authors contributed to 2 180 publications,resulting in an average number of authors per paper of 1.93.Researchers from all autonomous regions and municipalities in China had their health management research published (top five:Beijing,Jiangsu,Guangdong,Shanghai and Sichuan),expect for Qinghai,Tibet,Guizhou and Hainan.Forty-six authors had an occurrence frequency of ≥5.Forty-four keywords showed an occurrence frequency of ≥15 and centrality degree＞0,including health check-up,health education,hypertension,diabetes,life behavior intervention and student health management.Conclusions Health management research have made a rapid progress in China during recent years.Increasing number of research institutions and teams have involved in health management research.However,scientific research cooperation in the field of health management is relatively loose,and interdisciplinary,cross-reginal and interagency cooperation is insufficient.

Objective To investigate genotyps of Treponema pallidum (Tp) in several cities in Guangxi province. Methods A total of 300 patients with suspected early syphilis were enrolled from STD clinics in Guangxi between January 2012 and July 2016, and tissue fluid samples were collected from skin lesions. Silver staining was performed to detect Tp, and PCR to amplify the Tp polA gene for the diagnosis of early syphilis. Positive samples were subjected to PCR amplification of a 60-bp tandem repeat region within the arp gene, restriction fragment length polymorphism(RFLP)analysis of the tpr Ⅱgene after digestion with Mse Ⅰ enzyme and tp0548 genotyping. Results Finally, 215 patients were diagnosed with early syphilis, including 210(97.7%)patients positive for PCR and 105(48.8%)patients positive for silver staining, and the positive rate significantly differed between the two methods (χ2 = 103.01, P < 0.05). Among the PCR-positive samples, 190 could be genotyped by analysis of three target genes, and 17 genotypes were identified. The genotype 14d/f was predominant (45.3%, 86/190), followed by 15d/f (13.7%, 26/190), 16d/f(11.6%, 22/190), 17d/f(7.4%, 14/190), 13d/f(6.8%, 13/190), 10d/f(4.2%, 8/190), 18d/f(1.6%, 3/190), 16a/f(1.6%, 3/190), 5d/f(1.1%, 2/190), 7d/f(1.1%, 2/190), 12d/f(1.1%, 2/190), 16d/e(1.1%, 2/190), 14a/f(1.1%, 2/190), 9h/c(1.1%, 2/190), 15l/f(0.5%, 1/190), 25a/e(0.5%, 1/190), 15i/f(0.5%, 1/190). Conclusion Tp genotypes are diversified in patients with early syphilis in Guangxi, and the genotype 14 d/f is predominant.

In order to improve tensile property of vascular scaffold, we blended silk fibroin with novel human-like collagen with the mass ratio of 9:1, 7:3 and 5:5 (W/W), and then fabricated blood vessel tubular graft by freeze-drying process. We studied microstructure, mechanical properties, elements composites, degradability and biocompatibility of vascular scaffolds. These results showed that tubular scaffold with mass ratio 7:3 exhibited interconnected porous structure with pore size at (60 +/- 5) microm and porosity of 85%; achieved the desirable mechanical property (strain of 50% +/- 5% and stress of 332 +/- 16 kPa); had relatively slow degradation rate; could enhance cell adhesion and proliferation and had superior biocompatibility.
