Abstract： [Purpose/significance] The existing library borrowing data analysis mainly focuses on the subject classification of undergraduates borrowing books. This paper aims to analyze the library borrowing data from the perspective of self-improvement, and reveal the same or different manifestation of the deep level of consciousness of different college students. [Method/process] Based on the college students curriculum contents information and college students borrowing record data, it builds the self-improvement discipline knowledge structure consciousness, consciousness degree, and ability evaluation mathematical model, taking the two sessions of undergraduate curriculum, borrowing data as well as the school library collection data in a university as samples for analysis. [Result/conclusion] The results show that using the self-improvement evaluation mathematical model which is based on college students' library borrowing data, enables us to pass through the different lending behaviors of college students, and understand the self-improvement consciousness and ability of college students' discipline knowledge structure. Most of the undergraduates who have self-improvement knowledge structure consciousness have a low degree of self-improvement consciousness. There may not be much difference between the number of borrowing books and self-improvement knowledge structure. Students may differ in their awareness of the knowledge structure of different subjects through elective courses or independent reading.

Abstract： [Purpose/significance] Identifying expertise tags of scholars is the most critical task in scholar profiling. Expertise tags contribute to finding peer experts, clustering domain scholars and selecting reviewers.[Method/process] This study analyzed related factors on the scholar expertise in academic publications, then constructed a hierarchical analysis model on the weight allocation of the factors. The TextRank algorithm has been used to identify topical terms in Chinese corpus, and the conceptual linking technique in English corpus. The extracted terms, together with the previously analyzed factors have been combined to select the expertise tags of the scholars. In this study, a group of honored scholars of different domains have been selected. Their research expertise information from their resumes have been taken as evaluation benchmark. And the expertise tags extracted from their publications have been compared with the benchmark by human judgment and additional semantic similarity judgment.[Result/conclusion] The evaluation shows that the expertise tags of 71.9% scholars are acceptable for Chinese, and 77.2% for English. The experiment proves that the method proposed in this article is pragmatic and may lead to reasonable results. The chief innovation of this study lies in three aspects, Firstly, term extraction approaches that suit to different application conditions have been explored, such as the language of publication and the availability of domain knowledge base. Secondly, multiple features have been combined together to identify the expertise tags of scholars, including the content of publications, the substantial contribution to the publications of the scholars, and the influence to the domain of the publications. Thirdly, a reasonable experimental design and evaluation method is proposed, and the proposed approach has been verified by combining manual scoring and semantic calculation results.

Abstract： [Purpose/Significance] The huge economic benefits of Bt insect resistant genes have attracted great attention of relevant research institutions and enterprises at home and abroad, and these genes and technologies are transformed into their own exclusive rights by using intellectual property rights. Through statistical analysis of Bt insect resistant gene patents collected in 126 countries and regions around the world, this paper provides a reference for China in the development and industrial application of Bt insect resistant genes. [Method/Process] Based on the Global Patent Database of Smart Bud (PatSnap), the title, abstract and claim of the patent were taken as the focus of the search, and the patent analysis method was used to statistically analyze the Bt insect-resistant transgenic patents collected in the past 30 years since 1992. In the process of Bt anti-insect gene research, a large number of patent data were produced. After data cleaning, the "Bt strain", "detection method", "Bt insecticidal reagent" and other patents unrelated to the anti-insect gene were eliminated, and 2,988 patents were obtained, all of which were invention patents. The research status, research hotspots and development trends of global Bt pest resistance genes were studied from the aspects of total patent applications and trend, gene family classification, national/regional distribution, key technology fields, technology flow, institutional competitiveness, patent legalization status, and compound trait patents. [Results/Conclusions] Results show that the global Bt insect-resistant gene technology patent research and development trends, research hotspots and distribution technology gradually remain stable, the trend of patent application and disclosure in China is growing at the same time as that in the world. China's patent applications account for an increasing proportion of the global patent applications. But compared with international patent quality, there is still a gap between China and other countries. Multinational companies are the main body of Bt pest resistance gene market competition, and Chinese applicants are mainly scientific research institutions and universities. The cry1 family is the main target of Bt pest resistance gene patent application. The crystallized protein of Bacillus is a hot topic at present. The United States is the exporting country of Bt insect-resistant gene technology, while China is still in the stage of technology input. The patent failure rate of Bt insect resistance gene is much lower than the average level in this field. There is great potential in the study of fusion genes and gene superposition composite traits. Finally, the development prospects of Bt insect resistance gene technology in China were discussed.

Abstract： General practice research often pays attention not only to the physical health of patients, professional competence of doctors, and the quality of medical services, but also to the spiritual feelings of patients, motivation of doctors to practice, and the cooperation between doctors and patients. However, these are not resolved well only using quantitative research which is still dominated in the field of general practice. Mixed methods research which integrates qualitative and quantitative research, combining the advantages of both, can analyze specific problems more broadly and in depth, and increase the generalizability of research results, which is suitable for studying complex problems. However, the application of mixed methods research in general practice is still limited in China, and the standardization of its design and implementation needs to be improved. Therefore, this paper plans to introduce the key points in the design and implementation of mixed methods research from methodological lence, combining theory with practice, so as to provide reference for general practitioners who intend to carry out mixed methods research.

Abstract： Aiming at the problem of single structure style and less system variable for traditional chaotic system, we proposed a chaotic circuit. The circuit has more complex dynamic behaviors, higher sensitivity to variable and stronger anti-interference. With the change of circuit parameters, we discussed the different dynamic behaviors of the system in detail based on the adaptive stability criterion and chaos motion theory. In addition, we constructed the corresponding circuit and observed the system dynamics phenomena by oscilloscope. The dynamics phenomena are in accordance with the simulation results of Matlab, which further proves the feasibility and flexibility of the circuit. On this basis, we put forward and studied the multi-stage combination synchronization based on this system. By constructing different controllers, we realized the multi-stage combination synchronization among the eight systems. The simulation results show that the synchronization scheme has a good effect on convergence speed and precision.

Abstract： Objective To investigate the expression of ALDH1, CXCR4 and E-cadherin in gastric carcinoma and their roles in lymphatic metastasis. Methods Surgical specimens from 127 cases of gastric carcinoma were examined for expressions of ALDH1, CXCR4 and E-cadherin immuohistochemistry with 60 adjacent tissues as control. The associations ofALDH1, CXCR4 and E-cadherin with the clinicopathological pfeatures, 5-year survival rate and lymph node metastasis of the patients were analyzed. Results ALDH1, CXCR4 and E-cadherin were positive in 57.5% (73/127), 63.8% (81/127), and 36.2% (46/127) of the gastric carcinoma tissues, respectively, showing significant differences from the rates in the adjacent tissues (P<0.05). The expression of ALDH1 was significantly correlated with TNM stage and lymph node metastasis (P<0.05), CXCR4 was significantly correlated with the invasion depth, differentiation, TNM stage and lymph node metastasis of the tumor (P<0.05), and E-cadherin was significantly correlated with the invasion depth, differentiation and lymph node metastasis (P<0.05). The positivity rates of ALDH1, CXCR4 and E-cadherin were higher in cases with lymph node metastasis than in those without metastasis. E-cadherin expression was inversely correlated with ALDH1 and CXCR4 expression, and the latter two were positively correlated (P<0.001). Overexpressions of ALDH1 and CXCR4 and a decreased expression of E-cadherin were all related to a poor prognosis of the patients (P<0.05). The expressions ofALDH1, CXCR4 and E-cadherin were all independent prognostic factors of gastric carcinoma.Conclusion The expressions ofALDH1, CXCR4and E-cadherin are associatedwith the invasion, metastasis and prognosis of gastric carcinoma, and their combined detection provides important evidence for predictingtheprogressionandprognosisofgastriccarcinoma.

Abstract： Objective To observe the effect of Trichinella spiralis and its worm-derived proteins on cecal ligation and puncture(CLP)-induced sepsis in mice. Methods Eighty male BALB/c mice were randomly divided into sham-operated group, CLP group, Trichinella spiralis muscle larvae (ML) pre-infection group (ML + CLP group), soluble muscle larvae proteins (SMP) treatment group (SMP + CLP group) and excretory-secretory proteins (MES) treatment group (MES + CLP group). In ML + CLP group, the mice were orally infected with 300 Trichinella spiralis muscle larvae at 28 days before CLP and those in the other groups were intraperitioneally injected with PBS or SMP (25 µg/mice) or MES (25 µg/mice) 30 min after CLP. The general condition and 72-h survival after CLP of the mice were observed. The levels of alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN), creatinine (Cr), TNF-α, IL-6, IL-1β, IL-10 and TGF-β were measured at 12 h after the operation, and the pathological changes of the liver and idney were observed. Results Compared with the sham-operated mice, the mice in CLP group showed decreased 72-h survival, obviously increased ALT, AST, BUN, Cr, TNF-α, IL-6, IL-1β, IL-10, and TGF-β with hepatic cords disorder, hepatocytes swelling, glomerulus shrinkage, and renal tubular cell edema. Compared with CLP group, the mice in ML+CLP group showed lowered levels of ALT, AST, Cr, TNF-α and IL-1β and increased levels of IL-10 and TGF-β; in SMP + CLP group, the levels of ALT, AST, Cr, TNF-α and IL-1β were decreased and TGF-β increased. In MES + CLP group, the mice showed obviously increased 72-h survival with lowered levels of ALT, AST, BUN, Cr, TNF-α, IL-6 and IL-1β, increased levels of IL-10 and TGF-β, and alleviated liver and kidney damages. Conclusion Trichinella spiralis and its worm-derived proteins can decrease the levels of pro-inflammatory cytokines and increase immunomodulatory cytokines, and MES has more potent effect to reduce structural and functional damages of the liver and kidney.

Abstract： Objective To investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants. Methods The registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control). Results The preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05). Conclusion PROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.

Abstract： Objective To investigate the correlation of serum calcium levels and the risks of diabetes mellitus (DM) in middle-aged elderly men. Methods A total of 3386 male subjects aged 40-79 years were selected from two local communities of Beijing using stratified random sampling for this cross-sectional survey. The survey was conducted using questionnaires, and all the subjects underwent physical examination and blood tests of serum calcium, vitamin D and other biochemical parameters. The subjects were divided into normal glucose group, prediabetic group and diabetic group to compare their blood biochemical parameters and analyze the risk factors of diabetes. Results The prevalence of diabetes and pre-diabetes was 32.31% in the 3386 subjects surveyed. Serum calcium, vitamin D and Creatinine (Cr) levels were significantly higher in pre-diabetic and diabetic groups than in the non-diabetic group (P<0.05), and age, body mass index, serum calcium, vitamin D, and Cr levels differed significantly between the former two groups (P<0.05). The prevalence of diabetes increased significantly with serum calcium level (P<0.05). Logistic regression analysis showed that age, body mass index, serum calcium, and serum vitamin D levels were independent risk factors for diabetes (P<0.05). Conclusion Male diabetic patients have abnormal serum calcium levels. An increased age and increased serum calcium levels are associated with higher risks of diabetes, and age, serum calcium, serum vitamin D, Cr, and body mass index are all risk factors of diabetes in men.
