Magnetron Sputtering Coating of Protective Fabric Study on Influence of Thermal Properties  [PDF]
Yunqi Zhai, Xiaoxia Liu, Li Xiao
Journal of Textile Science and Technology (JTST) , 2015, DOI: 10.4236/jtst.2015.13014
Abstract: Protective fabric has been the focus of research of the textile materials. In recent years, with the rapid development of the robot, its protective fabric has been developed quickly. This paper is making Al, SiO2 as the sputtering target materials, magnetron sputtering as technology, on the back of the fabric sputtering Al layer, double-layer Al/SiO2 film, and three-layer SiO2/Al/SiO2 film through the test of the heat reflectivity of the composite materials. As a result, the highest reflectivity of the SiO2/Al/SiO2, SiO2/Al, and single Al film is 64.97%, 57.38%, and 51.59%, respectively. It is clear that reflectivity increases with the increase of the membrane layer. In three kinds of membrane structures, there are nanometer Al particles in the formation of dense membrane structure, which can improve the reflectivity of the fabric.

Jianwu Xiao, Wenxing Kang, Shaohua Yin, Hong Zhai
Low Carbon Economy (LCE) , 2010, DOI: 10.4236/lce.2010.11004
Abstract: Considering the valuation of forest stands based on revenue from wood sales, concession policy (such as carbon sub- sidies) and associated costs, the paper focuses on the stochastic control model to study the forest asset dynamic manage- ment. The key contribution is to find the optimal dynamic strategy about harvesting quantity in the continual and multiple periods in conditions of stochastic commodity price and timber growth by using portfolio approach. Finally, an analytical optimal strategy is obtained to analyze the quantification relations through which some important conclusions about the optimal forest management can be drawn.

Psychosocial and spiritual needs of patients with chronic diseases: validation of the Chinese version of the Spiritual Needs Questionnaire
Arndt Büssing,Xiao-feng Zhai
Journal of Integrative Medicine (JIM) , 2013,
Abstract: OBJECTIVE: Even in secular societies, a small portion of patients find their spirituality to help cope with illness. But for the majority of patients, psychosocial and spiritual needs are neither addressed nor even considered a relevant factor by health care professionals. To measure such specific needs, the Spiritual Needs Questionnaire (SpNQ) was developed. The aim of this study was to validate the Chinese version of the SpNQ (SpNQ-Ch) and thus to measure psychosocial and spiritual needs of Chinese patients. METHODS: This was a cross-sectional study among 168 patients with chronic diseases who were recruited in the Changhai Hospital of Traditional Chinese Medicine, Shanghai, China using standardized questionnaires. We performed reliability and factor analyses, as well as analyses of variance, first order correlations and regression analyses. RESULTS: The 17-item SpNQ-Ch had a similar factorial structure as the original version with two main and three minor factors which accounted for 64% of variance, and internal consistency estimates (Cronbach’s α) ranging from 0.51 to 0.81. Included were the 4-item scale Inner Peace Needs, the 5-item scale Giving/Generativity Needs, the 5-item scale Religious Needs (with 2 sub-constructs, Praying and Sources), and a 3-item scale Reflection/Release Needs. In Chinese patients with cancer (63%), pain affections (10%), or other chronic conditions (23%), the needs for Giving/Generativity (which refer to categories of Connectedness and Meaning) and Inner Peace Needs scored highest, while Religious Needs and the Reflection/Release Needs scored lower. CONCLUSION: The SpNQ-Ch is congruent with its primary version, and can be used in future studies with the mostly nonreligious patients from China. First findings indicate specific psychosocial and spiritual needs which should be addressed by health care professionals to support patients in their struggle with chronic illness in terms of psycho-emotional stabilization, finding hope and meaning, and thus achieving peaceful states of mind despite chronic illness.
Lactulose: an effective preventive and therapeutic option for ischemic stroke by production of hydrogen
Xiao Chen, Xiao Zhai, Zhimin Kang, Xuejun Sun
Medical Gas Research , 2012, DOI: 10.1186/2045-9912-2-3
Abstract: Currently stroke is the second leading cause of death in the Western world, ranking after heart diseases and before cancer [1], causing 10% of deaths worldwide [2]. It is estimated that stroke could soon be the most common cause of death worldwide [3]. An ischemic stroke can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism), which may lead to rapidly developing loss of brain functions as a result of disturbance in the blood supply to the brain [4]. Stroke can affect patients physically, mentally, emotionally, or a combination of the three and bring heavy burdens to society.Ischemia induces production of reactive oxygen species (ROS), which can react with and damage a number of cellular and extracellular elements. Evidence has accumulated showing that ROS are involved in cerebral ischemia and reperfusion. During cerebral ischemia, cerebral blood flow was partially or completely cut off in brain regions supplied by the occluded vessels. Reoxygenation due to spontaneous or thrombolytic reperfusion offers oxygen as a substrate for a number of enzymatic oxidation, constantly generating ROS like superoxide anion radicals(O2·-) and hydrogen peroxide(H2O2) [5]. ROS are known to be able to result in macromolecular damages including lipid peroxidation, protein oxidation, and DNA oxidation, which result in ischemic brain injury [6]. Clinically, a number of recent studies have revealed that stroke and oxidative stress are closely related and excess oxidative stress may have deleterious effects on clinical outcome in acute ischemic stroke [7,8]. Therefore, antioxidants have been considered in prevention and treatment of stroke and certain agents with antioxidative effects did have neuroprotective effects [9].In recent years, experimental evidences have documented that without influencing other less potent ROS, important in intracellular signaling, molecular hydrogen possesses the ability to selectively neutralize ONOO- and ?OH, the most c
Impacts of Atmospheric Conditions on Influenza in Southern China. Part I. Taking Shenzhen City for Example  [PDF]

Open Journal of Air Pollution (OJAP) , 2012, DOI: 10.4236/ojap.2012.13008
Abstract: In this study, we analyse the relationship between the occurrences of influenza in Shenzhen, a rapid developing city in subtropic regions of southern China with over 10 million populations, and the vapor pressure (VP), the concentrations of atmospheric pollutants (SO2, NO2, PM10) for the period of 2003 - 2008. Using the data such as the rate of Influ- en-za-Like-Illness (ILI (%)), the concentrations of pollutants and vapor pressure, we show quite different results from pre-vious research conducted in other regions in China which are dominated by temperate climate and with influenza out-break in Winter and Autumn. Our results show that the rate of ILI in Shenzhen reaches its maximum in Summer and minimum in Winter and the concentrations of pollutants were significantly correlated with ILI (%), there are significant positive correlations between ILI (%) and VP which can explain over 25% the variance of ILI (%) variations. Quite surprisingly, both atmospheric SO2 and PM10 concentrations are negatively correlated with ILI (%), this is because acid deposition may limit the spread of disease, the seasonal variations of acid rain in Shenzhen could contribute to the sea-sonality of its influenza. Furthermore, there are some significant correlations between preceding VP and SO2 and PM10 concentrations to ILI occurrence and such connections can be used for ILI predictions.
The Processing of Dui-construction in Chinese  [PDF]

Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.26086
Abstract: In the present study, I examined the Dui-construction from a psycholinguistic perspective. Two experiments on the processing of Dui-constructions have been carried out to reexamine the findings of previous experiments on empty subjects in English and Japanese. There are two advantages of using the Chinese Dui-construction over English and Japanese. Firstly, Chinese is similar to English in that the verb is located before the empty subject of an infinitival clause. It is therefore possible to verify whether the verb control information is delayed or not in this case. Secondly, Chinese is similar to Japanese in that they both allow scrambling of arguments. As such, I can examine whether the recency hypothesis applies to Chinese or not. The results indicated that 1) The control information of the verb is accessed immediately; 2) The recency hypothesis is not supported in the processing of Duii-constructions. In other words, there exists a language-specific processing system independent of the general recency strategy.
Development and application of a water pollution emergency response system for the Three Gorges Reservoir in the Yangtze River, China

Qiang He,Shujuan Peng,Jun Zhai,Haiwen Xiao,

环境科学学报(英文版) , 2011,
Abstract: There are many watercraft and production accidents in the Three Gorges Reservoir Area (TGRA) of the Yangtze River in China every year. Accidents threaten the water quality of the 1085 km2 surface area of the TGRA and millions of local people if oil and chemical leakage were to occur. A water pollution management system for emergency response (WPMS ER) was therefore designed for the management of pollution in this area. An integrated geographic information system (GIS)-based water pollution management information system for the TGRA, called WPMS ER TGRA, was developed in this study. ArcGIS engine was used as the system development platform, and Visual Basic as the programming language. The models for hydraulic and water quality simulation and the generation of body-fitted coordinates were developed and programmed as a dynamically linked library file using Visual Basic, and they can be launched by other computer programs. Subsequently, the GIS-based information system was applied to the emergency water pollution management of a shipwreck releasing 10 tons of phenol into the Yangtze River during two hours. The results showed that WPMS ER TGRA can assist with emergency water pollution management and simulate the transfer and di usion of accidental pollutants in the river. Furthermore, it can quickly identify the a ected area and how it will change over time within a few minutes of an accident occurring.

Xiao-feng Zhai,Chang-quan Ling
Journal of Integrative Medicine (JIM) , 2013,
Abstract: BACKGROUND: Disease recurrence is a main challenge in treatment of hepatocellular carcinoma (HCC). There is no generally accepted method for preventing recurrence of HCC after resection. OBJECTIVE: To compare the efficacy of a traditional herbal medicine (THM) regimen and transarterial chemoembolization (TACE) in preventing recurrence in post-resection patients with small HCC.DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a multicenter, open-label, randomized, controlled study, which was undertaken in five centers of China. A total of 379 patients who met the eligibility criteria and underwent randomization were enrolled in this trial. One hundred and eighty-eight patients were assigned to the THM group and received Cinobufacini injection and Jiedu Granule, and the other 191 patients were assigned to the TACE group and received one single course of TACE.MAIN OUTCOME MEASURES: Primary outcome measures were the annual recurrence rate and the time to recurrence. Incidence of adverse events was regarded as the secondary outcome measure.RESULTS: Among the 364 patients who were included in the intention-to-treat analysis, 67 patients of the THM group and 87 of the TACE group had recurrence, with a hazard ratio of 0.695 (P = 0.048). Median recurrence-free survival of the patients in the THM and TACE groups was 46.89 and 34.49 months, respectively. Recurrence rates at 1, 2 and 3 years were 17.7%, 33.0% and 43.5% for the THM group, and 28.8%, 42.5% and 54.0% for the TACE group, respectively (P = 0.026). Multivariate analysis indicated that the THM regimen had a big advantage for prolonging the recurrence-free survival. Adverse events were mild and abnormality of laboratory indices of the two groups were similar.CONCLUSION: In comparison with TACE therapy, the THM regimen was associated with diminished risk of recurrence of small-sized HCC after resection, with comparable adverse events.TRIAL REGISTRTION IDENTIFIER: This trial was registered in the Chinese Clinical Trial Registry with the identifier ChiCTR–TRC-07000033.

Journal of Hematology & Oncology , 2013, DOI: 10.1186/1756-8722-6-15
Abstract: Objective We conducted a prospective, randomized, open-label, multicenter study to compare busulfan plus fludarabine (BuFlu) with busulfan plus cyclophosphamide (BuCy) as the conditioning regimen in allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute myeloid leukemia (AML) in first complete remission (CR1). Methods Totally 108 AML-CR1 patients undergoing allo-HSCT were randomized into BuCy (busulfan 1.6 mg/kg, q12 hours, -7 ~ -4d; cyclophosphamide 60 mg/kg.d, -3 ~ -2d) or BuFlu (busulfan 1.6 mg/kg, q12 hours, -5 ~ -2d; fludarabine 30 mg/m2.d, -6 ~ -2d) group. Hematopoietic engraftment, regimen-related toxicity (RRT), graft-versus-host disease (GVHD), transplant related mortality (TRM), and overall survival were compared between the two groups. Results All patients achieved hematopoietic reconstitution except for two patients who died of RRT during conditioning. All patients obtained complete donor chimerism by day +30 post-transplantation. The incidence of total and III-IV RRT were 94.4% and 81.5% (P = 0.038), and 16.7% and 0.0% (P = 0.002), respectively, in BuCy and BuFlu group. With a median follow up of 609 (range, 3–2130) days after transplantation, the 5-year cumulative incidence of TRM were 18.8 ± 6.9% and 9.9 ± 6.3% (P = 0.104); the 5-year cumulative incidence of leukemia relapse were 16.5 ± 5.8% and 16.2 ± 5.3% (P = 0.943); the 5-year disease-free survival and overall survival were 67.4 ± 7.6% and 75.3 ± 7.2% (P = 0.315), and 72.3 ± 7.5% and 81.9 ± 7.0% (P = 0.177), respectively in BuCy and BuFlu group. Conclusion Compared with BuCy, BuFlu as a myeloablative condition regimen was associated with lower toxicities and comparable anti-leukemic activity in AML-CR1 patients undergoing allo-HSCT.
