The specific fragment of Pneumococcal surface protein A(PspA)and Pneumococcal Surface Adhesin A(PsaA)gene was amplified by PCR from Streptococcus pneumonia 5 and Streptococcus pneumonia 19.The amplified fragnent of PspA and PsaA gene was ligated into pET-27b(+)vector and transformed into BL 21 E.coli for expression and obtain the expressive production of PspA and PsaA.Induced by IPTG,the expression level was as high as 75 % of the total disolube protein.The result showed that the recombinant plasmid could express a specific 75 kDa and 37 kDa fusion protein in E.coli BL 21,which showed the good immunogenicity and a broadly cross reactivity with the other serotypes.

Objective To compare the therapeutic effects and safety of monopolar and bipolar radiofrequency (RF) ablation used during cardiac surgery to treat atrial fibrillation.
Methods We retrospectively studied a total of 81 patients with chronic atrial fibrillation who underwent open cardiac surgery with concomitant RF ablation between January 2007 and March 2011. Fifty-eight patients received bipolar RF ablation and 23 received monopolar RF ablation, respectively. The sinus rhythm restoration rate, the procedural duration, the frequency of severe perioperative complications, and mortality were compared between the two groups.
Results The sinus rhythm restoration rate did not differ significantly between the two groups after follow-up of 15.1 ± 12.6 months (P=0.199). The frequencies of severe perioperative complications and mortality were also similar in the two groups. The total procedural time using bipolar RF ablation was significantly shorter than that using monopolar ablation (19.7±4.6 minutes vs. 28.1±8.5 minutes, P<0.001).
Conclusions Both monopolar and bipolar RF ablation are safe and effective in treating chronic atrial fibrillation patients during open cardiac surgery, but bipolar RF ablation is more convenient in practice.

Chinese medicinal formulae (CMF) were usually used in the clinics of traditional Chinese medicines (TCM), which were critical for modernization of Chinese medicine to shed light on the interaction between CMF and biological organisms. However, correlation between system and part, macroscopic actions and microcosmic mechanism, ADME process and pharmacologic actions were usually neglected. The put-forward of integrative pharmacology provided a feasible approach to solve the problem of the fragmentation of TCM. For the past years, we applied the strategy of integrative pharmacology to study Yuanhu Zhitong prescription( YZP) systematically, and established two modes, chemical fingerprints-metabolism fingerprints-network targets and intestinal absorption-activity evaluation-data mining, to establish the interaction rule between the chemical composition and biological activity from multiple levels, such as the calculation and in vitro/vivo, which provided proof for the quality control, pharmacodynamic material basis and pharmacological action of YZP. In this paper, we summarized the related progresses of the research of YZP.

OBJECTIVETo summarize the effectiveness of Chinese and Western integrative medicine in treating medium and advanced lung cancer, and to provide guidelines for clinical application.

METHODSFor this metaanalysis, a comparative search of Chinese medicine data in Chinese National Knowledge Infrastructure (CNKI) and Chinese BioMedical Literature Database (CBM) was undertaken to identify articles related to randomized comparative research of Chinese and Western integrative medicine in treating medium and advanced lung cancer between 1996 to 2006. Quality of life (QOL) was estimated using RevMan 4.2 software for data processing, adopting the odd ratio (OR) and the 95% confidence interval (CI).

RESULTSThrough meta-analysis of 10 qualified articles, the results were as follows: the merging effectiveness of QOL [OR=3.80, 95% CI (2.65, 5.47)]; the rate of survival [OR=3.44, 95% CI (2.04, 5.80)]; the tumor response rate [OR=1.88, 95% CI (1.37, 2.58)]; the tumor developing rate [OR=0.33, 95% CI (0.23, 0.48)]. Significant differences existed between the Chinese and Western integrative medicine treatment group and the Western treatment group (P<0.01).

CONCLUSIONSChinese and Western integrative medicine treatment of medium and advanced lung cancer has shown to improve patients' QOL and survival rate; it also can control tumor development in the short term.

The aim of this study is to identify the present status of the scientific and technological personnel in the field of traditional Chinese medicine (TCM) resource science. Based on the data from Chinese scientific research paper, an investigation regarding the number of the personnel, the distribution, their output of paper, their scientific research teams, high-yield authors and high-cited authors was conducted. The study covers seven subfields of traditional Chinese medicine identification, quality standard, Chinese medicine cultivation, harvest processing of TCM, market development and resource protection and resource management, as well as 82 widely used Chinese medicine species, such as Ginseng and Radix Astragali. One hundred and fifteen domain authority experts were selected based on the data of high-yield authors and high-cited authors. The database system platform "Skilled Scientific and Technological Personnel in the field of Traditional Chinese Medicine Resource Science-Chinese papers" was established. This platform successfully provided the retrieval result of the personnel, output of paper, and their core research team by input the study field, year, and Chinese medicine species. The investigation provides basic data of scientific and technological personnel in the field of traditional Chinese medicine resource science for administrative agencies and also evidence for the selection of scientific and technological personnel and construction of scientific research teams.

OBJECTIVETo investigate general states of the work locus of control and explore the relationship between work locus of control and occupational stress in oil workers.

METHODS582 oil workers were investigated by using the General Questionnaire and Occupational Stress Measure Inventory.

RESULTSThere were significant differences in WCLS score between two age groups (= 30 years old group and < 30 years old group) (t = 2.093, P = 0.037). Values of interpersonal relationship, person responsibility, promotion, participation, autonomy, task consistency, challenge, job satisfaction, mental health, self-esteem and coping strategies were higher in the group of internal locus of control; values of role ambiguity, working prospect, depression and social support were higher in the group of external locus of control (P < 0.05). Work locus of control had positive relation with role ambiguity, working prospect, depression, and social support, and negative with interpersonal relationship, promotion, participation, task consistency, challenge, job satisfaction, mental health, self-esteem and coping strategies. In the regression analysis, work locus of control was the major predictive factor of work satisfaction.

CONCLUSIONWork locus of control is associated with many occupational stress factors. The group of extrinsic work locus of control experience more stress in oil workers.
