Background Hospitalizations for asthma and chronic obstructive pulmonary disease (COPD) exacerbations frequently occur in Thailand. National trends in hospital outcomes are essential for planning preventive strategies within the healthcare system. We examined temporal trends in in-hospital outcomes, including mortality rate, length of stay (LOS), and expenses for reimbursement in adults hospitalized for asthma and COPD exacerbations in southern Thailand.Methods A retrospective, population-based study on adults hospitalized for exacerbations of asthma and COPD was carried out using data from the National Health Security Office in southern Thailand. Baseline demographic and in-hospital outcome assessments were conducted on 19,459 and 66,457 hospitalizations for asthma and COPD, respectively, between 2017 and 2021.Results Significant reductions in hospital admissions for exacerbations of asthma and COPD were observed over time, particularly in 2020/2021. From 2017 to 2021, the in-hospital mortality rate for asthma rose from 3.2 to 3.7 deaths per 1,000 admissions (P<0.05). The rates for COPD admissions, on the other hand, reduced from 20.3 to 16.4 deaths per 1,000 admissions between 2017 and 2020, but subsequently increased to 21.8 in 2021 (P<0.05). The prominent contributor to the higher mortality rate was found to be increasing age. Nonetheless, the average LOS for both asthma and COPD decreased slightly over the study period. The total expenses for reimbursing exacerbations of asthma and COPD per hospitalisation have risen significantly each year, with a particularly notable increase in 2020/2021.Conclusion During 2017-2021, exacerbations of asthma and COPD in Thailand continued to account for significant in-hospital mortality rates and reimbursement expenses, despite the overall decrease in hospitalizations and slight fluctuations in the LOS.

Protection against severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection of inactivated vaccines is not well characterized in people with comorbidities, who are at high risk of severe infection. We compared the risk of SARS-CoV-2 infection after complete vaccination with Sinopharm/BBIBP in people with comorbidities (e.g., autoimmune diseases, cardiovascular disease, chronic lung disease, and diabetes) with healthy individuals using a Cox-proportional hazard model. In July-September 2021, a total of 10 548 people (comorbidities, 2143; healthy, 8405) receiving the complete primary series of vaccination with Sinopharm/BBIBP in Bangkok, Thailand were prospectively followed for SARS-CoV-2 infection through text messaging and telephone interviewing for 6 months. A total of 295 infections from 284 participants were found. HRs (95% CI) of individuals with any comorbidities did not increase (unadjusted, 1.02 (0.77-1.36), P = 0.89; adjusted, 1.04 (0.78-1.38), P = 0.81). HRs significantly increased in the subgroup of autoimmune diseases (unadjusted, 2.64 (1.09-6.38), P = 0.032; adjusted, 4.45 (1.83-10.83), P = 0.001) but not in cardiovascular disease, chronic lung disease, or diabetes. The protection against SARS-CoV-2 infection of the Sinopharm vaccine was similar in participants with any comorbidities vs. healthy individuals. However, the protection appeared lower in the subgroup of autoimmune diseases, which may reflect suboptimal immune responses among these people.

Kaempferiae Parviflorae Rhizoma is the dried rhizome of Kaempferia parviflora in Zingiberaceae. It is originated and widely distributed in Thailand and other tropical and subtropical regions, where it has been used as food and medicine for thousands of years. K. parviflora is also planted in Yunnan and other places of China, but its traditional Chinese medicine properties are not clear, which greatly limits its compatibility with traditional Chinese medicines. In this article, the English and Chinese literatures of K. parviflora were searched from Web of Science, PubMed, Scopus, CNKI, Wanfang, and VIP databases for research and analysis. The medicinal properties of K. parviflora were preliminarily discussed based on the theory of traditional Chinese medicine under the guidance of clinical application and research literatures. The traditional Chinese medicine properties of K. parviflora were inferred as follows: flat, acrid, sweet. The channel tropisms of K. parviflora included kidney, spleen, stomach, and liver. The function of K. parviflora included tonifying kidney to strengthen essence, tonifying Qi and invigorating spleen, soothing liver and relieving depression. K. parviflora was clinically applied for the diseases such as syndrome of kidney essence deficiency, sex apathy, deficiency of spleen Qi, lassitude and asthenia, a weary spirit, obesity, diabetes, liver Qi stagnation, depression, and restless. The equivalent of dry power is 1.5 g·d~(-1) and the equivalent of decoction is 1.5-6 g·d~(-1). The determination of traditional Chinese medicine properties of K. parviflora has indeed laid a theoretical foundation for its application in the field of traditional Chinese medicine and enriched traditional Chinese medicine resources.

OBJECTIVE: This study explored the rejuvenation mechanisms of Thai polyherbal medicines using different approaches, including in vitro methods, as well as a well-defined nematode model, Caenorhabditis elegans. METHODS: THP-R-SR012 decoction was selected from 23 polyherbal medicines, based on metal-chelating and chain-breaking antioxidant capacities. The influences of this extract on the survival and some stress biomarkers of C. elegans under paraquat-induced oxidative stress were evaluated. Furthermore, lifespan analysis and levels of lipofuscin accumulation were examined in senescent nematodes. The phytochemical profile of THP-R-SR012 was analyzed. RESULTS: Supplementation with THP-R-SR012 decoction significantly increased the mean lifespan and reduced the oxidative damage to C. elegans under oxidative stress conditions. Further, THP-R-SR012 supplementation slightly influenced the lifespan and the level of lipofuscin accumulation during adulthood. Antioxidant-related phytochemical constituents of THP-R-SR012 decoction were rutin, naringenin, 3,4-dihydroxybenzoic acid, gallic acid, glycyrrhizic acid, demethoxycurcumin and 18α-glycyrrhetinic acid. CONCLUSION The antioxidant potential of THP-R-SR012 was due to its scavenging properties, its enhancement of antioxidant-related enzyme activities, and the presence of the antioxidant-related compound. These results support the traditional use of THP-R-SR012 decoction as a tonic for nourishing and strengthening the whole body.

Lancang-Mekong Cooperation is a new type of subregional cooperation mechanism initiated and built by China and other five countries of the Lancang-Mekong subregion, namely Laos, Myanmar, Thailand, Cambodia, and Vietnam. Countries in the Lancang-Mekong subregion are geographically and culturally connected, and they have nurtured their unique traditional medicine. By combing the history of traditional medicine exchanges between China and other Lancang-Mekong countries and their progress of modern research, this paper summarized the challenges and opportunities of traditional medicine cooperation in the Lancang-Mekong subregion. It has been found that many regional cooperation mechanisms coexist for a long time in the Lancang-Mekong subregion and the medicinal resources are abundant. However, the degree of their development and utilization varies, and modern scientific research is insufficient. Lancang-Mekong Cooperation has provided a strong support for integrating the advantageous resources in Lancang-Mekong subregion countries and making progress together. Focusing on the development and protection of medicinal resources, this paper puts forward a new path of cooperation in the intellectual property rights and characteristic seed resource protection, the compilation of universal herbal pharmacopoeia in various countries, the research and development of public health products, and the construction of traditional herbal industry bases, thus enabling the traditional medicine to better protect the public health and building a human health community.

Arthropod-borne diseases, such as malaria and dengue fever, have frequently beset five countries(Cambodia, Vietnam, Laos, Myanmar, and Thailand) in the tropical rainy Lancang-Mekong region, which pose a huge threat to social production and daily life. As a resort to such diseases, chemical drugs risk the resistance in plasmodium, non-availability for dengue virus, and pollution to the environment. Traditional medicinal plants have the multi-component, multi-target, and multi-pathway characteristics, which are of great potential in drug development. Exploring potential medicinals for arthropod-borne diseases from traditional medicinal plants has become a hot spot. This study summarized the epidemiological background of arthropod-borne diseases in the Lancang-Mekong region and screened effective herbs from the 350 medicinal plants recorded in CHINA-ASEAN Traditional Medicine. Based on CNKI, VIP, and PubMed, the plants for malaria and dengue fever and those for killing and repelling mosquitoes were respectively sorted out. Their pharmacological effects and mechanisms were reviewed and the material basis was analyzed. The result is expected to serve as a reference for efficient utilization of medicinal resources, development of effective and safe drugs for malaria and dengue fever, and the further cooperation between China and the other five countries in the Lancang-Mekong region.
