Characteristics of the HIV/AIDS Epidemic among People Aged≥50 Years in China during 2018–2021

Objective This study aimed to determine the current epidemiological status of PLWHA aged≥50 years in China from 2018 to 2021.It also aimed to recommend targeted interventions for the prevention and treatment of HIV/AIDS in elderly patients.Methods Data on newly reported cases of PLWHA,aged≥50 years in China from 2018 to 2021,were collected using the CRIMS.Trend tests and spatial analyses were also conducted.Results Between 2018 and 2021,237,724 HIV/AIDS cases were reported among patients aged≥50 years in China.The main transmission route was heterosexual transmission(91.24%).Commercial heterosexual transmission(CHC)was the primary mode of transmission among males,while non-marital non-CHC([NMNCHC];60.59%)was the prevalent route in women.The proportion of patients with CHC decreased over time(Z=67.716,P<0.01),while that of patients with NMNCHC increased(Z=153.05,P<0.01).The sex ratio varied among the different modes of infection,and it peaked at 17.65 for CHC.The spatial analysis indicated spatial clustering,and the high-high clustering areas were mainly distributed in the southwestern and central-southern provinces.Conclusion In China,PLWHA,aged≥50 years,were predominantly infected through heterosexual transmission.The primary modes of infection were CHC and NMNCHC.There were variations in the sex ratio among different age groups,infected through various sexual behaviors.HIV/AIDS cases exhibited spatial clustering.Based on these results,the expansion of HIV testing,treatment,and integrated behavioral interventions in high-risk populations is recommended to enhance disease detection in key regions.

Historical review and reflections on the participation of acupuncture and moxibustion in the treatment of epidemics in the People’s Republic of China (from 1950 until now)

Since the establishment of the People’s Republic of China, both the Communist Party and the government have placed great emphasis on the advancement of traditional Chinese medicine. Acupuncture and moxibustion have been actively involved in combating major epidemics such as malaria, schistosomiasis, and COVID-19. This article conducts a historical review of these three significant cases to elucidate how the acupuncture community has effectively utilized its unique advantages and characteristics through theoretical discussions, clinical practices, experimental research, as well as receiving administrative leadership and political support from the Communist Party of China and government. We provide an objective evaluation of their effectiveness while summarizing historical experiences to serve as a reference for future utilization of acupuncture and moxibustion therapy in epidemic relief efforts. Additionally, propose four suggestions: strengthening Party leadership and enhancing political support;timely summarization of experiences to establish programs and systems;deepening scientific research by integrating experimental findings with clinical practice;focusing on public awareness campaigns and education to solidify grassroots foundations.

Rice （Oryza sativa L.） is originated from Asia and more than 90% of rice is produced inAsia. As the most important cereal crop in the world, rice is the staple food for over 1/3 global population, while this proportion is over 60% in Asia （Wan 2010）. In order to maintain the most important role that rice has played in Asian agriculture and ensure food security in the world, especially in Asia,

Characteristics of Temperature Change in China over the Last 2000 years and Spatial Patterns of Dryness/Wetness during Cold and Warm Periods

This paper presents new high-resolution proxies and paleoclimatic reconstructions for studying climate changes in China for the past 2000 years. Multi-proxy synthesized reconstructions show that temperature variation in China has exhibited significant 50–70-yr, 100–120-yr, and 200–250-yr cycles. Results also show that the amplitudes of decadal and centennial temperature variation were 1.3℃ and 0.7℃, respectively, with the latter significantly correlated with long-term changes in solar radiation, especially cold periods, which correspond approximately to sunspot minima. The most rapid warming in China occurred over AD 1870–2000, at a rate of 0.56°± 0.42℃（100 yr）^（-1）; however, temperatures recorded in the 20 th century may not be unprecedented for the last 2000 years, as data show records for the periods AD 981–1100 and AD1201–70 are comparable to the present. The ensemble means of dryness/wetness spatial patterns in eastern China across all centennial warm periods illustrate a tripole pattern： dry south of 25°N, wet from 25°–30°N, and dry to the north of 30°N. However, for all centennial cold periods, this spatial pattern also exhibits a meridional distribution. The increase in precipitation over the monsoonal regions of China associated with the 20 th century warming can primarily be attributed to a mega El Nino–Southern Oscillation and the Atlantic Multidecadal Oscillation. In addition, a significant association between increasing numbers of locusts and dry/cold conditions is found in eastern China. Plague intensity also generally increases in concert with wetness in northern China, while more precipitation is likely to have a negative effect in southern China.

Preliminary Analysis of Climatic Variation during the Last 39 Years in China

The preliminary analysis of climatic variation in China during the last 39 years has been made in this paper. The results show that although the global climate is getting warmer, some parts of China are cooling. The warming only occurs in Northeast, North and the west part of Northwest China while the areas between about 35°N and Nanling Mountain, east of the Tibetan Plateau in China are getting cooler. The cooling centers are located in Sichuan, the south part of Shaanxi and the north part of Yunnan respectively. According to the theory of greenhouse effect, there are much precipitation at low and high latitudes and less precipitation in middle latitude. However, the precipitation in the most parts of China has been decreased, especially in North and Northwest China.

Analysis of Climate Change in the Coastal Zone of Eastern China, against the Background of Global Climate Change over the Last Fifty Years: Case Study of Shandong Peninsula, China

The climate change in Shandong Peninsula, China was analyzed in this paper by the non-parametric Mann-Kendall test, Accumulated Difference Curve and Order Cluster Analysis methods, based upon the datas of annual mean, maximum and minimum temperature and annual precipitation, precipitation from June to September over the past 50 years. Results obtained showed a number of observations: 1) The annual mean temperature of Shandong Peninsula showed a significant increasing trend, with a distinct abrupt change point detected around 1990, during the past 5 decades. The warming of the Peninsula over the last 50 years was due mainly to the significant increase of annual minimum temperature. The annual maximum temperature demonstrated a mixed trend of decreasing and increasing, but was statistically insignificant, and no abrupt change was detected;2) The annual precipitation exhibited a decreasing trend during the past 5 decades, with an abrupt change detected around 1980 at most stations;but there was an earlier transition point at 1966, at a few stations. The reduction in precipitation, from June to September, was responsible mainly for the decrease of annual precipitation. Besides, the proportion of the June-September precipitation in the year declined slightly over the last 50 years;3) In comparison, the temperature evolution in Shandong Peninsula was basically consistent with most parts of China, but warmed at a faster rate over the same period;the decreasing trend of precipitation was more significant compared with the other climate zones of China. Within the Peninsula, the abrupt change of temperature and precipitation in the Southeast was earlier than that in the Northwest;the reduction of precipitation was larger in the Southeast while the increase of temperature was more significant in the Northwest. This research was of great importance to understand the climate change and its environmental effects in the coastal zone.

Molecular diversity of barley yellow dwarf virus-PAV from China and the Czech Republic

Wheat yellow dwarf disease(BYD),caused by different species of barley/cereal yellow dwarf viruses(B/CYDVs),is one of the most serious cereal diseases in China and the Czech Republic.Because genetic diversity of the virus directly influences disease epidemiology,the molecular diversity and population structure of 24 Chinese isolates and 16 the Czech Republic isolates of BYDV-PAV from different regions in two countries were analyzed by sequencing their coat protein(CP)and readthrough protein(RTP)domain(RTD)genes and comparing the sequences with six CP and 16 RTP sequences of BYDVPAV isolates from the NCBI database based on nucleotide identity position,phylogenetic analysis and nucleotide diversity.Nucleotide identities between the Chinese and the Czech Republic isolates for the CP were 76.6–99.4%,73.9–89.1%for RTD(ORF5),respectively.The Chinese and the other country isolates showed 74.7–99.2%nucleotide identity for RTP(ORF3+ORF5).Phylogenetic analysis of CP sequences showed that 20 Chinese isolates clustered in the same clade,but the other four Chinese isolates clustered in another clade with the isolates from the Czech Republic and other counties.The population of BYDV-PAV in China had greater nucleotide variability and was more divergent than that in the Czech Republic.Geographical and ecological factors but not hosts might contribute to the population differences in the two countries.

Republic of Congo’ Wood Products Exported to China: Insight of the Characteristics, Trends, and Perspectives for Sustainable Trade

Wood products trade sector remains crucial for many countries’ economies. This is also for the Republic of Congo (RC) where wood is the second most exported natural resource. In this study, we aimed to determine the predominant wood products exported from the RC to China from 2007 to 2019, analyze the trends related to this trade, compare the quantities of wood products exported to China and other destinations, and determine the perspectives for the sustainable trade. The descriptive study using graphs and tables, non-parametric technique Kruskal-Wallis, pairwise comparisons, and SWOT analysis made up the methodological basis for this study. IBM SPSS Statistics 26 software supported data processing. The results showed that logs were mainly exported to China, 92.585% of the three major wood products quantity (Logs, Wet sawnwood, and Dried sawnwood). Volume distributions between products categories differ significantly (Sig. = 0.000 < α = 0.05). Besides, a significant volume (69.32%) was exported to China compared to the other destinations, and volume distributions between different destinations differ significantly (Sig. = 0.000 < α = 0.05). The SWOT analysis describes weaknesses, strengths, opportunities, and potential threats related to RC’ wood products trade sector. The prospects for sustainable trade in wood products between the RC and China lie in establishing a good governance in the timber sector, supporting the emergence of domestic operators, and improving the business climate.
