To interpret the traditional Chinese medicine (TCM) theory by the network technology, in order to promote the modernization and programming of studies on compatibility of TCMs. In this paper, efforts were made to express the direct interactions between drugs through the herb-pair network, analyze the community characteristics of the network and its relations with blood-Qi theory, and study the expression of blood-Qi theory on the herb-pair network through prescriptions. According to the findings, the herb-pairs network showed a strong community structure characteristics; Each community is composed of a series of herb pairs with close correlations, and either blood efficacy or Qi efficacy but not both of them. Based on that, the 386 single TCM ingredients involved by the herb-pair network were divided into three types of communities: Blood (B) community, Qi (Q) community and uncertain community. According to the statistical results of 262 prescriptions mapped onto the three types of communities, if a prescription contains single herbs of the Q community, the probability that it contains single herbs o the B community is 99.84%; Meanwhile, there are 140 prescriptions containing single herbs of both the Q community and the B community. The result is completely coincident with the TCM Blood-Qi theory that single herbs belong to both Q and B communities or the B community, because Qi regulation leads to blood regulation, but not vice versa. For example, a patient with hemorrhage due to trauma or blood-heat, Qi tonifying prescriptions may aggravate hemorrhage. In this paper, authors found high-recognition macroscopic network numerical characteristics to network data reference for judging rationality of new prescriptions, and proved human blood and Qi relations from the perspective of data analysis.

Objective To know the nursing scientific research status in recent years,and to reveal the differences between Chinese nursing scientific researches and foreign nursing scientific researches,in order to promote the rapid development of nursing cause in China.Methods Five Chinese journals of nursing and four foreign nursing journals were analyzed covered China National Knowledge Infrastructure (CNKI),PubMed and Google data ranged from 2008 to 2013.By adopting bibliometrics method,regional distribution,the number of people participation,the cooperation between units,the source of financial funding,research content and nature of Chinese nursing research papers were analyzed,and also compared to research content and nature of foreign nursing journals.Results The amounts of published papers were 1 527 pieces.The geographical distribution of research papers were all spread over 28 provinces,autonomous regions sand municipalities directly under the central government,most of which was Guangdong province [12.64％ (193/1 527)];The majority of research papers were completed by single unit and more than five people,which about [68.4％(1 045/1 527)],[38.6％(589/1 527)],respectively;Provincial level of research papers were more than national level [81.4％(1 243/1 527) vs.18.6％(284/1 527)];The papers focused on the clinical nursing research [37.8％(577/1 527)] and clinical basic nursing research [34.6％(529/1 527)].Almost researches were descriptive research,while 40.7％(622/1527) of which were clinical analysis.Foreign nursing scientific researches paid more attention to psychological research and nursing profession which were related to humanities and investigation was major method used;Compared with the foreign nursing papers at the same time,the number of Chinese nursing research papers increased rapidly (P ＜ 0.05);Papers were completed more than five units rapidly increased compared with the pre-upgrade,as well as the national subjects,the difference was statistically significant (P ＜ 0.05).Conclusions The number of nursing research programs tended to increase year by year and the enthusiasm of nurses participating in scientific research was higher than before.Different units needed to further strengthen cooperation in scientific research.The research content and direction were diversity,which had not yet formed central tendency.The research method was still limited to descriptive studies,and the creativity of the research methods was needed,especially laboratory research.

Objective To evaluate the efficacy of modification and care improvement in endotracheal tubes (ETTs) to prevent ventilator associated pneumonia (VAP) in patients receiving mechanical ventilation (MV).Methods PubMed,China National Knowledge Infrastructure (CNKI) were searched,literature information was extracted and classified according to the inclusion criteria,the data were statistically analyzed.Results Totally 46 clinical research articles and 6 laboratory research articles were involved,the data showed that polyurethane (PU) cuff [23.809％ (35/147)],silver-coated ETTs [4.830％ (37/766)],subglottic drainage duct [19.492％ (759/3 894)],discontinuous subglottic drainage[13.603％ (256/1 882)] were associated with a decreased incidence of VAP compared with polyvinyl (PVC) cuff [40.179％ (45/112)],non-silver-coated ETTs [7.537％ (56/743)],conventional ETTs[45.733％ (1 088/2 379)],continuous subglottic drainage [25.000％ (503/2 012)],the differences in the incidence of VAP were statistically significant,respectively,P＜ 0.05.The incidence of VAP in cylindrical PU cuff was 25.000％ (8/32),the tapered PU cuff was 21.875％ (7/32),the difference in the incidence of VAP was not statistically significant.Conclusions The modification of the ETTs and the care improvement can effectively reduce the incidence of VAP.

Gonorrhea is a sexually transmitted disease caused by Neisseria gonorrhoeae,and substantially harms human health and socioeconomic development.Due to inappropriate treatment and the presence of drug resistance genes in patients,antibiotic resistance has emerged in Neisseria gonorrhoeae,such as resistance to penicillin,tetracycline,ciprofloxacin,or other antibiotics.Currently,extended-spectrum cephalosporins (ESCs) are the first-line treatment of gonococcal infection.With the wide use of ESCs,the sensitivity of Neisseria gonorrhoeae to ESCs has been decreasing gradually,and there have been reports on cases of treatment failure in clinical practice.In order to control gonorrhea and deal with drug resistance in Neisseria gonorrhoeae,combined therapy,alternative therapy and new drugs have been developed in clinic.

Objective To assess the value of fiberoptic ductoscopy (FDS) in the diagnosis of nipple discharge.Methods Clinical records of 800 patients with nipple discharge undergoing FDS from October 1998 to July 2003 were retrospectively reviewed. Results Diagnoses established by FDS were pathologically confirmed in 92 2% of patients with papilloma (202/219), in 86 7% of patients with papillomatosis (13/15), and in 95 2% of patients with breast cancer (40/42). The total diagnostic accordance rate was 92 0% (266/289). Conclusions FDS in the diagnosis of nipple discharge is sensitive and of great clinical significance.
