COPENHAGEN, April 30 (Xinhua) -- As traditional Chinese medicine (known as TCM in Europe) becomes increasingly popular worldwide and has gradually been regarded as a useful component to Western medical treatments, Denmark is no stranger to such trends.According to a study published by the University of Copenhagen in mid-Feb., up to one-third of Danish hospitals choose complementary or alternative therapies, including TCM methods, to treat pain, cancer, mental disease, tumors and infertility. Acupuncture remains the most widely-practiced form of these treatments, used in some 97 percent of the cases.The nationwide acceptance of acupuncture and massage therapists, the growing ranks of herbal practitioners, and the hosting of an annual pan-Scandinavian TCM conference since 2007, all underline the popularity of alternative medicine, including the TCM, in the country.However, the overall market presence of TCM, and herbal medicines in particular, is relatively small in Denmark and Europe at large. As many European policymakers insist that traditional herbal medicines "are neither scientifically documented nor tested according to Western requirements," these treatments face difficulties in obtaining licenses and boosting sales in Europe.In fact, despite their historical pedigree and widely-accepted efficacy, TCM products are often classified as "healthcare products" or "food," rather than "drugs" in European markets.A big challenge for TCM products to gain more access to the continent is the EU's Traditional Herbal Medicinal Products Directive, which stipulates that all such products must obtain authorization if they are to be sold within the EU, starting May 1, 2011.The directive says producers must prove the product in question has been used for 30 years, 15 of which within the EU, so as to ensure its safety.While licensing is expected to be onerous and expensive, Denmark has tried to bring TCM products into the Western medical mainstream from as early as 2005. The country's well-developed biochemical and medical industry, modernized agriculture and horticulture sectors and a strong track record of cooperative research in these fields, has helped TCM's cause.For instance, Traditional Complementary Medicine Denmark, a company helping herbal product makers market their goods in Western countries, uses modern biotechnology processes and clinical trials to scientifically verify and document the efficacy of existing herbal medicines.It also advises herbal product makers on how to align their standards with European requirements so as to acquire the necessary sales licenses. Sometimes, simple solutions like clearer and more detailed labeling of a TCM product's ingredients can help improve its marketability. Patent applications and drug approvals procedures must follow, before the product can access the EU pharmaceutical market, usually in pill form.Investing in herbal medicine also makes financial sense for Denmark, as it is encourages development of low-bulk, high-value agricultural products, which can be easily transported all over the globe.Development Centre Aarslev, a Danish agro-research body and partner of TCM Denmark, studies the active ingredients contained in medicinal plants and their impact on human health conditions such as cardiovascular problems, diabetes and allergies. One of the earliest collaborations it undertook with a producer of herbal medicine showed the effectiveness of extracts from the hips of the dog rose plant in treating rheumatoid arthritis.A spokesperson for the institution said, "We have documented analytical evidence which shows that arthritis patients can reduce their consumption of conventional anti-arthritis drugs by up to 50 percent, if they combine them with the herbal drug based on dog rose hips."Given Denmark's population of 5.5 million people, this could translate into savings of 200 million U.S. dollars a year on anti-arthritis medication, the spokesperson added.Other plant-based interventions could hold wider public health benefits. TCM practitioners say herbal medicines can improve blood circulation in humans, and contain naturally-occurring antioxidants which can reduce the risks of heart attacks and better regulate cardiovascular functions. This has potentially wide-ranging benefit for Western societies, where heart disease is a major threat.Heart disease was the most common cause of death in Denmark until 2000, and cardiovascular disease the commonest until 2008, with cancer now ranking the biggest killer.In fact, TCM herbal remedies are also considered a good choice for cancer treatment, as certain plants contain hormone-like substance which can influence hormone-dependent cancers, such as breast and prostate cancer.TCM supporters say the obvious benefit of such an intervention is the avoidance of more commonly-used chemotherapy and radiation treatments which often produce severe side-effects in patients. Relevant herbal therapies can help strengthen cancer patient's immune system, reduce side-effects of chemotherapy and radiation therapy, and alleviate other symptoms of the disease.Given the many potential benefits of TCM, the EU's tightening of rules may appear harsh. Still, TCM is considered a relatively novel approach to medicine in Europe. Moreover, the dominant market share and general clout of the chemical-based, Western pharmaceutical industry also makes it difficult for traditional remedies to stake their claim.

BEIJING, Jan. 22 (Xinhua) -- Chinese President Hu Jintao's latest state visit to the United States bore rich fruit and opened a new chapter of cooperation between the two countries, Foreign Minister Yang Jiechi said Saturday.The tour, from Tuesday through Friday, came at the beginning of the second decade of the 21st century, on the 40th anniversary of the resumption of contact between the two countries and on the opening year of China's 12th five-year plan for national socioeconomic development, Yang noted.Meanwhile, the international situation was witnessing deep and complicated changes, and the China-U.S. relationship was forging ahead with increasing momentum while inevitably encountering some differences and disputes, he said.Against such a backdrop, the Chinese president held frank and in-depth talks with his U.S. counterpart, Barack Obama, and many other senior political figures, and reached important consensus on bilateral relations and a host of major regional and global affairs, Yang said.During the tightly scheduled trip, which saw Hu attend nearly 20 events in Washington and Chicago within 68 hours, the Chinese leader also reached out to the U.S. public, conveying China's resolution to advance China-U.S. ties, highlighting China's commitment to peaceful development and presenting China's image of peace, development, opening-up and progress, Yang said.The U.S. and international media, he added, attached great importance to and spoke highly of Hu's trip, hailing it as a historic visit at a crucial moment and whose significance was manifested partly in the top level reception with full pomp and ceremony given by the U.S. government.In summary, the latest step in China-U.S. diplomacy achieved rich results and cast a far-reaching influence not only upon the two countries themselves but upon the whole world, the Chinese foreign minister said.

WASHINGTON, May 17 (Xinhua) -- A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins University researchers suggests.The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene ( SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women.Following up studies in female mice that first linked a deficiency in these receptors for HDL -- the so-called "good" or " healthy" cholesterol -- and infertility, researchers report finding the same link in studies of women with a history of infertility.The findings has been published on-line this week in the journal Human Reproduction.If the new study's findings hold up on further investigation, the John Hopkins team says they not only will offer clues into a genetic cause of some infertility, but could also lead to a treatment already shown to work in mice."Infertility is fairly common and a lot of the reasons for it are still unknown," warns endocrinologist Annabelle Rodriguez, an associate professor of medicine at the Johns Hopkins University School of Medicine and the lead author. "Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility."

BEIJING, Feb. 4 (Xinhua) -- The Chinese government Friday initiated a relief and assistance program for eight drought-ravaged provinces, said a statement on the website of Ministry of Agriculture.The government had implemented a grade II emergency response, meaning a 24-hour alert, daily damage reports, and the dispatching of experts and relief materials, said the statement.The ministry had sent teams to help with relief work in the provinces of Hebei, Shanxi, Jangsu, Anhui, Shandong, Henan, Shaanxi and Gansu, said the statement.The four-month drought had affected 35.1 percent of wheat crops, -- 96.11 million mu (6.4 million hectares) -- accounting for 21.7 percent of total farmland in the provinces, it said.The wheat growing area in the eight provinces accounted for more than 80 percent of the country's total, said the statement.The provinces have received little rainfall since October last year, it said.

WASHINGTON, May 12 (Xinhua) -- Early initiation of antiretroviral treatment in people infected with HIV prevents them from transmitting the virus to their partners, according to findings released Thursday from a large-scale international clinical study.The study, known as HPTN 052, was designed to evaluate whether antiretroviral drugs can prevent sexual transmission of HIV infection among couples in which one partner is HIV-infected and the other is not. The results are the first of their kind from a major randomized clinical trial.Led by Myron Cohen, of the University of North Carolina, the research found that treating HIV-infected individuals with antiretroviral therapy (ART) when their immune systems are still relatively healthy led to a 96 percent reduction in HIV transmission to their partners.This critical new finding convincingly demonstrates that early treatment of infected individuals can have a major impact on the spread of the epidemic.Study investigators enrolled 1,763 couples who were not eligible for ART by WHO standards in nine countries around the world. All couples were at least 18 years of age. The vast majority of the couples (97 percent) were heterosexual, which precludes any definitive conclusions about effectiveness in men who have sex with men.Couples were randomly assigned to one of two study groups. In the first group, the HIV-infected partner initiated antiretroviral therapy (ART) as soon as the couple enrolled in the study (the immediate treatment group); in the second group, infected partners did not begin ART until their CD4+ counts fell to between 200 and 250 cells/mm3 or they developed an AIDS-related illness (the delayed treatment group). Couples in both groups received HIV primary care, counseling and condoms.Results of this research study, which was scheduled to conclude in 2015, are being released early, after the independent data and safety monitoring board (DSMB) determined that the benefits of early treatment were clear.
