In the last twenty years, in the United States and other Western countries, dry needling （DN） became a hot and debatable topic, not only in academic but also in legal fields. This White Paper is to provide the authoritative information of DN versus acupuncture to academic scholars, healthcare professional administrators, lawmakers, and the general public through providing the authoritative evidence and experts＇ opinions regarding critical issues of DN versus acupuncture, and then reach consensus. DN is the use of dry needles alone, either solid filiform acupuncture needles or hollow-core hypodermic needles, to insert into the body for the treatment of muscle pain and related myofascial pain syndrome. DN is sometimes also known as intramuscular stimulation, trigger points （TrP） acupuncture, TrP DN, myofascial TrP DN, or biomedical acupuncture. InWestern countries, DN is a form of simplified acupuncture using biomedical language in treating myofascial pain, a contemporary development of a portion of Ashi point acupuncture from Chinese acupuncture. It seeks to redefine acupuncture by reframing its theoretical principles in a Western manner. DN-like needling with filiform needles have been widely used in Chinese acupuncture practice over the past 2,000 years, and with hypodermic needles has been used in China in acupuncture practice for at least 72 years. In Eastern countries, such as China, since late of 1800s or earlier, DN is a common name of acupuncture among acupuncturists and the general public, which has a broader scope of indications, not limited to treating the myofascial pain.

A novel nanocomposite of rigid polyurethane foam was prepared by the polymerization of a sucrose-based polyol, a glycerol-based polyol and polymeric methylene diphenyl diisocyanate in the presence of cellulose whiskers. The cell morphology of the resulting foams was examined by scanning electron microscopy which showed both the pure foam and the nanocomposite foam had homogeneous cell dispersion and uniform cell size of approximately 200 μm. Analysis of the foams by Fourier transform infrared(FT-IR) spectroscopy indicated that both samples exhibited signals attributed to the polyurethane including the NH stretching and bending vibrations at 3320 cm^(-1) and 1530 cm^(-1), the OC=O vibration at 1730 cm^(-1) and the CO-NH vibration at 1600 cm^(-1). FT-IR analysis of the nanocomposite indicated that cellulose whiskers were crosslinked with the polyurethane matrix as the signal intensity of the OH stretch at 3500 cm^(-1) was significantly reduced in comparison to the spectral data acquired for a control sample prepared from the pure polyurethane foam mixed with cellulose whiskers. According to ASTM standard testing procedures, the tensile modulus, tensile strength and yield strength of the nanocomposite foam were found to be improved by 36.8%, 13.8% and 15.2%, and the compressive modulus and strength were enhanced by 179.9% and 143.4%, respectively. Dynamic mechanical analysis results testified the improvements of mechanical properties and showed a better thermal stability of the nanocomposite foam.

China＇s 2007 Open Government Information Regulations is widely considered as a milestone in the country＇s information policy history and is praised as a ＂sunshine program＂. The Environmental Information Disclosure Decree was the first to operationalize these general regulations into a sectorai information disclosure system on environment. This study assessed the implementation of the environmental information disclosure system about six months after the Decree took effect on May 1, 2008. Through reviewing the websites of all 31 provincial Environmental Protection Bureaus and the Ministry of Environmental Protection, conducting an experiment with actual information disclosure request, and through interviews with all provincial Environmental Protection Bureaus, this article concluded that the implementation of the environmental information disclosure system still fails short. Future improvements should focus on further publicity of the regulations and decree to enhance public participation, the establishment of an independent evaluation and supervision system for information disclosure, the exchange of experiences and best practices among provincial Environmental Protection Bureaus, and on strengthening the legal status of environmental information disclosure.
