New Insights into Human Resource Management of Large Public Hospitals with Multi Campuses in China  [PDF]
Jialin Yang, Huafeng Cheng
Journal of Human Resource and Sustainability Studies (JHRSS) , 2015, DOI: 10.4236/jhrss.2015.33016
Abstract: Human resource departments of large public hospitals in China deal with new challenges caused by multi-campus structure, such as increased labor demand, difficulty in cost management, lack of professional talents, restriction on employing way and etc. Delphi Method and Focus Group were used as the chief methods to analyze the problems. Countermeasures are researched as staffing optimization, performance management, forming Expert Center, establishing HRM Framework based on the positions among campus and restricting the human resource department. The researches break away from traditional human resource practices, develop new application for future trends, and adapt to the changes of business in the country’s public hospital reform.
Cost-effectiveness analysis of different rescue therapies in patients with lamivudine-resistant chronic hepatitis B in China
Wu Bin,Shen Jinfang,Cheng Huafeng
BMC Health Services Research , 2012, DOI: 10.1186/1472-6963-12-385
Abstract: Background Several rescue therapies have been used in patients with lamivudine (LAM)-resistant chronic hepatitis B (CHB); however, the economic outcome of these therapies is unclear. The object of the current analysis was to evaluate the lifetime cost-effectiveness of rescue therapies among patients with LAM-resistant CHB. Methods A Markov model was developed to simulate the clinical course of patients with LAM-resistant CHB. From the perspective of Chinese health care, a lifetime cost-utility analysis was performedfor 4 rescue strategies: adefovir (ADV), entecavir (ETV) or tenofovir (TDF) monotherapy and combination therapy using LAM and ADV. A hypothetical cohort of 45-year-old patients with genotypic or clinical LAM-resistant CHB entered the model, and the beginning health state was LAM-resistant CHB without other complications. The transition probabilities, efficacy and resistance data for each rescue therapy as well as the costs and utility data were estimated from the literature. The discount rate (3%) utilized for costs and benefits. Sensitivity analyses were used to explore the impact of uncertainty on the results. Results In LAM-resistant HBeAg-positive and HBeAg-negative CHB cohorts, TDF monotherapy and combination therapy were on the efficiency frontier for both positive and negative populations. Compared with no treatment, the use of combination therapy cost an additional $6,531.7 to gain 1 additional quality-adjusted life year (QALY) for HBeAg-positive patients and $4,571.7 to gain 1 additional QALY for HBeAg-negative patients. TDF monotherapy for HBeAg-positive patients, shows greater increase in QALYs but higher incremental cost-effectiveness ratio (ICER) in comparison with combination therapy. In probabilistic sensitivity analyses, combination therapy was the preferred option for health care systems with limited health resources, such as Chinese health care system. Conclusion In Chinese patients with LAM-resistant CHB, combination therapy is a more cost-effective option than the competing rescue therapies.
Literature Review on Educational Attainment of Migrant Children in China  [PDF]
Huafeng Zhang
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.47029
Abstract: This paper reviews the literature on migrant children’s educational attainment in Chinese urban cities. The review attempts to explore the central government’s policy of institutional segregation and the barriers established by local policy on the issue of migrant children’s access to education. Furthermore, the review examines the direct consequences of policies that limit migrant children’s school enrollment, thus affecting their educational and psychological performance and their social integration in urban areas. Lack of equal access to education for migrant children is also closely correlated with education inequality and poverty, which reinforce each other and form a trap for poor families. Finally, this paper endeavors to review the contribution of recent studies on migrant children’s education in urban cities, with a focus on quantitative data and methods applied by recent studies on the topic. At the same time, the review discusses the limitations of current studies and potential areas for future research.
A Method for Service-Oriented Personalized Requirements Analysis  [PDF]
Huafeng Chen, Keqing He
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.41007
Abstract: The development of Web service has changed the process of software production, and requirements engineering becomes the key issue of service-oriented software engineering. Meantime, it reduces the degree of difficulty of software production, which facilitates end-users to customize software according to their personalized requirements. The paper proposes a method for service-oriented personalized requirements analysis, which is based on domain goal model and process model. The method can inform users of potential errors in requirements by detecting the correctness of requirements, which is driven by users’ personalized operations on goal models, and customize personalized processes to satisfy users’ requirements by reusing domain processes. The personalized processes are the basis for Web service discovery and composition.
Genetic Variation of ITGB3 Is Associated with Asthma in Chinese Han Children
Yan Zhang, Yuling Han, Liang Dong, Huafeng Yu, Lu Cheng, Xiuxia Zhao, Mingjie Ding
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0056914
Abstract: Previous studies have demonstrated that integrins are involved in the aetiology of asthma. Several single-nucleotide polymorphisms (SNPs) in the integrin β3 (ITGB3) gene are significantly associated with asthma in Western populations. Given the important roles of environmental exposures in the development of asthma, we evaluated the associations between six SNPs in ITGB3 and asthma in Chinese Han children. A total of 321 unrelated Chinese children with asthma and 315 healthy children were recruited for the study. SNP genotyping was performed by high-resolution melting analysis (HRM). The selected SNPs were well genotyped by HRM, and SNP rs3809865 in the 3′ untranslated region (3′UTR) of ITGB3 was found to be strongly associated with asthma (adjusted p = 0.004). The minor allele of rs3809865 showed a protective effect against asthma (OR: 0.59; 95% CI: 0.43–0.8). The seed regions of two miRNAs (hsa-mir-124 and hsa-mir-506) were predicted to bind to the sequence containing rs3809865 by TargetScan and PITA. Luciferase reporter assays demonstrated that the T allele of rs3809865 was more efficiently targeted by hsa-mir-124 than was the A allele, which suggested that rs3809865 could affect the binding of hsa-mir-124 to ITGB3. Furthermore, the transfection of A549 cells with hsa-mir-124 resulted in the downregulation of ITGB3 expression. Our results revealed that rs3809865 was significantly associated with asthma due to its effect on the binding of hsa-mir-124 to ITGB3.
RTT realization of quantum affine superalgebras and tensor products
Huafeng Zhang
Mathematics , 2014, DOI: 10.1093/imrn/rnv167
Abstract: We use the RTT realization of the quantum affine superalgebra associated with the Lie superalgebra $\mathfrak{gl}(M,N)$ to study its finite-dimensional representations and their tensor products. In the case $\mathfrak{gl}(1,1)$, the cyclicity condition of tensor products of finite-dimensional simple modules is determined completely in terms of zeros and poles of rational functions. This in turn induces cyclicity of some particular tensor products of Kirillov-Reshetikhin modules related to $\mathfrak{gl}(M,N)$.
Representations of Quantum Affine Superalgebras
Huafeng Zhang
Mathematics , 2013, DOI: 10.1007/s00209-014-1330-6
Abstract: We study the quantum affine superalgebra $U_q(Lsl(M,N))$ and its finite-dimensional representations. We prove a triangular decomposition and establish a system of Poincar\'{e}-Birkhoff-Witt generators for this superalgebra, both in terms of Drinfel'd currents. We define the Weyl modules in the spirit of Chari-Pressley and prove that these Weyl modules are always finite-dimensional and non-zero. In consequence, we obtain a highest weight classification of finite-dimensional simple representations when $M \neq N$. Some concrete simple representations are constructed via evaluation morphisms.
Asymptotic representations of quantum affine superalgebras
Huafeng Zhang
Mathematics , 2014,
Abstract: We study representations of the $q$-Yangian, the upper Borel subalgebra with respect to RTT realization of the quantum affine superalgebra associated with the Lie superalgebra $\mathfrak{gl}(M,N)$. Following the work of Hernandez-Jimbo, we construct inductive systems of Kirillov-Reshetikhin modules by using a cyclicity result of tensor products of these modules we established recently, and realize their inductive limits as modules over the $q$-Yangian, extending the asymptotic construction of Hernandez-Jimbo to the super case. Then, we propose a new asymptotic construction on the inductive limits of the same inductive systems, resulting in modules over the full quantum affine superalgebra depending on an additional parameter. $q$-character and Gelfand-Tsetlin basis for these two kinds of modules are also investigated.

Mathematics , 2015, DOI: 10.1007/s11005-015-0797-3
Abstract: The universal $R$-matrix of the quantum affine superalgebra associated to the Lie superalgebra $\mathfrak{gl}(1,1)$ is realized as the Casimir element of certain Hopf pairing, based on the explicit coproduct formula of all the Drinfeld loop generators.

Huafeng Zhang
Mathematics , 2015,
Abstract: We study a certain family of finite-dimensional simple representations over quantum affine superalgebras associated to general linear Lie superalgebras, the so-called fundamental representations: the denominators of rational $R$-matrices between two fundamental representations are computed; a cyclicity (and so simplicity) condition on tensor products of fundamental representations is proved.
