Objective To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. Methods The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. Results A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 104 km2 in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 104 km2 in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). Conclusions The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.

It was emphasized that in the process of collecting clinical questions, "treatable population" and "alleviable outcome indicators" for a specific Acup-Mox intervention with certain therapeutic effect should be focused on, so as to highlight the pertinence of clinical questions of Acup-Mox guidelines in terms of population and outcome elements.

Treatment of Aural Vertigo Ménière's Disease with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Ménière's disease （MD） is an inner ear disease characterized by vertigo， tinnitus， hearing loss， and ear stuffiness. Modern therapies such as drugs， surgery， and vestibular function rehabilitation have limited effects in relieving the symptoms and reducing the recurrence. Traditional Chinese medicine （TCM） can alleviate the symptoms of MD with simple operation and mild adverse reactions while emphasizing psychological adjustment. The TCM treatment of MD is individualized depending on different stages and pathogenic factors. The internal treatment mainly targets phlegm， dampness， water， wind， fire， deficiency， and blood stasis. External interventions include acupuncture and moxibustion. This paper reviewed the published articles about the treatment of MD with TCM. In recent five years， the published studies were mainly clinical trials and experience discussion （or case reports）， and few reports of fundamental research were published. In these studies， the Western medicine diagnosis of MD mostly refers to the Diagnostic Basis and Efficacy Evaluation of Ménière's Disease （Guiyang， 2006） and the Guidelines for Diagnosis and Treatment of Ménière's Disease （2017）， while the TCM diagnosis mostly refers to the Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine issued by the National Administration of TCM in 1994. The efficacy was mostly evaluated based on clinical efficacy， scales， syndrome scores， pure tone audiometry， etc.， while caboratory indexes were rarely used. The available clinical studies about the treatment of MD with TCM generally have low quality of evidence and single intervention means. In the future， the research on the treatment of MD with TCM can be improved by standardizing the research program， improving the quality of evidence， exploring more intervention methods， and strengthening basic research.

Planning of ecologically suitable areas for Ligusticum chuanxiong under background of soil cadmium pollution / 中国中药杂志

Chuanxiong Rhizoma is a traditional Chinese medicinal material mainly produced in Sichuan and Chongqing of China. In recent years, the cadmium content in Chuanxiong Rhizoma produced in most of the genuine producing areas has exceeded the standard, which makes Chuanxiong Rhizoma difficult to be exported. To solve the problem of excessive cadmium content in soil, this study employed the MaxEnt model to simulate the potential geographic distribution of Ligusticum chuanxiong and evaluate important environmental factors, and re-plan its ecologically suitable areas based on the mineral distribution characteristics and soil cadmium pollution status. The results showed that the places suitable for L. chuanxiong growing covered an area of 335 523.69 km~2, mainly in central and eastern Sichuan, southern Shaanxi and most parts of Chongqing. Among them, the highly suitable areas of L. chuanxiong were mainly concentrated in Chengdu, Ya'an, Deyang, and Mianyang. Solar radiation, annual precipitation, and annual range of temperature were evaluated as important variables affecting the distribution of L. chuanxiong, with the contribution rates of 62.3%, 13.3%, and 6.8%, respectively. In addition, Qionglai county, Chongqing county, Mianyang city(Youxian district and Fucheng district), Qingchuan county, and Xinjin county were classified into the first-class ecologically suitable zone, covering a total area of 2 768.87 km~2. The se-cond-class ecologically suitable zone was even wider, involving such counties as Tongjiang county, Renshou county, Jianyang county, and Nanjiang county, and the total area reached 43 616.92 km~2. The re-planning of the ecologically suitable areas for L. chuanxiong has provided strong data support for the cultivation and resource development of L. chuanxiong and also new ideas for solving the problem of excessive cadmium content in L. chuanxiong.

Applying Biomod2 for modeling of species suitable habitats:a case study of Paeonia lactiflora in China / 中国中药杂志

Paeonia lactiflora is an important medicinal resource in China. It is of great significance for the protection and cultivation of P. lactiflora resources to find the suitable habitats. The study was based on the information of 98 distribution sites and the data of 20 current environmental factors of wild P. lactiflora in China. According to the correlation and importance of environmental factors, we selected the main environmental factors affecting the potential suitable habitats. Then, BCC-CSM2-MR model was employed to predict the distribution range and center change of potential suitable habitat of wild P. lactiflora in the climate scenarios of SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 during 2021-2100. The ensemble model combined with GBM, GLM, MaxEnt, and RF showed improved prediction accuracy, with TSS=0.85 and AUC=0.95. Among the 20 environmental factors, annual mean temperature, monthly mean diurnal range of temperature, temperature seasonality, mean temperature of the warmest quarter, precipitation of the wettest month, precipitation seasonality, precipitation of the driest quarter, and elevation were the main factors that affected the suitable habitat distribution of P. lactiflora. At present, the potential suitable habitats of wild P. lactiflora is mainly distributed in Inner Mongolia, Heilongjiang, Jilin, Liaoning, Hebei, Beijing, Shaanxi, Shanxi, Shandong, Gansu, Xinjiang, Tibet, and Ningxia, and concentrated in the northeastern Inner Mongolia, central Heilongjiang, and northern Jilin. Under future climate conditions, the highly sui-table area of wild P. lactiflora will shrink, and the potential suitable habitat will mainly be lost to different degrees. However, in the SSP5-8.5 scenario, the low suitable area of wild P. lactiflora will partially increase in the highlands and mountains in western China including Xinjiang, Tibet, and Qinghai during 2061-2100. The distribution center of wild P. lactiflora migrated first to the northeast and then to the southwest. The total suitable habitats were stable and kept in the high-latitude zones. The prediction of the potential geo-graphical distribution of P. lactiflora is of great significance to the habitat protection and standardized cultivation of this plant in the future.

A new stage for healthy China： new characteristics and urgency of public health / 上海预防医学

Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research， we believe that five aspects need to be prioritized for a strong system. First， we should change the perspective on public health， using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”， to lead the public health system development. Second， we should develop a suitable public health system and continuously improve the health capacity for governance. Third， we should make it clear that the goal of building a strong system is not far-fetched， and we need to consolidate the existing institutional advantages of China’s public health system： when encountering major problems， we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However， we need to make up for shortcomings one by one， especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth， we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19， so that efficient mechanisms to deal with major issues can be used in routine work， and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response，so as to achieve the balanced development of regions categories and units.Finally， it is necessary to strengthen the coordination of government and research institutions， in the aspects of technological innovation， talent team building and accurate consulting services， and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.

Evaluation of clinical efficacy of a kind of digital complete denture / 北京大学学报(医学版)

OBJECTIVE@#To compare the clinical efficacy of a kind of complete dentures fabricated using computer aided design/computer aided manufacturing (CAD/CAM) workflow with that of the complete denture fabricated using conventional workflow.@*METHODS@#Twenty edentulous patients were included in this prospective, single-blind, self-controlled clinical trial. Two pairs of complete dentures were fabricated for each participant: one using the functional suitable denture (FSD) system with CAD/CAM, and the other using conventional fabrication workflow. In the final delivery appointment, the conventional dentures worn by the participant for 3 months at first. Then the participant swapped to wear digital denture for another 3 months. The patients' satisfaction and oral health related quality of life (OHRQoL) were measured using the visual analogue scale (VAS) and oral health impact profile (OHIP-20E) at baseline, 2 weeks, 1 month, 2 months, and 3 months following denture delivery. In addition, the masticatory efficiency of each pair of dentures was measured after three months adaptation period for each type of dentures.@*RESULTS@#The VAS scores of the twenty patients in FSD denture group on general satisfaction, ease of cleaning, ability to speak, esthetics, stability and oral health status on these six domains were higher than that of conventional denture group 3 months after delivery. While the VAS cores in FSD denture group on comfort, ability to chew and ability to chew up were the same as those of conventional denture group. But there was no significant difference (P>0.05). The VAS score on each domain in FSD denture group was higher than that of conventional denture group 3 months after delivery, three domains of which reached statistical significance (P < 0.05), involving functional limitation, psychological discomfort and total. The masticatory performance of the FSD denture (1.20±0.54) was slightly higher than that for the conventional denture (1.16±0.53), but the difference did not reach statistical significance (P=0.691).@*CONCLUSIONS@#The clinical efficacy of the FSD complete denture is comparable to that of the conventional complete denture. As for patient satisfaction and oral health related quality of life, FSD dentures received comparable scores as conventional complete dentures did.

Prediction of the globally ecological suitability of Panax quinquefolius by the geographic information system for global medicinal plants (GMPGIS) / 中国天然药物

American ginseng (Panax quinquefolius L.) is a well-known Asian traditional herbal medicine with a large market demand. The plant is native to eastern North America, and its main producing areas worldwide are decreasing due to continuous cropping obstacles and environmental changes. Therefore, the identification of maximum similarities of new ecological distribution of P. quinquefolius, and prediction of its response to climate change in the future are necessary for plant introduction and cultivation. In this study, the areas with potential ecological suitability for P. quinquefolius were predicted using the geographic information system for global medicinal plants (GMPGIS) based on 476 occurrence points and 19 bioclimatic variables. The results indicate that the new ecologically suitable areas for P. quinquefolius are East Asia and the mid-eastern Europe, which are mainly distributed in China, Russia, Japan, Ukraine, Belarus, North Korean, South Korea, andRomania. Under global climate change scenarios, the suitable planting areas for P. quinquefolius would be increased by 9.16%-30.97%, and expandingnorth and west over the current ecologically suitable areas by 2070. The potential increased areas that are ecologically suitable include northern Canada, Eastern Europe, and the Lesser Khingan Mountains of China, and reduced regions are mainly in central China, the southern U.S., and southern Europe. Jackknife tests indicate that the precipitation of the warmest quarter was the important climatic factor controlling the distribution of P. quinquefolius. Our findings can be used as auseful guide for P. quinquefolius introduction and cultivation in ecologically suitable areas.

Study on suitable areas of Lamiophlomis rotata in Sichuan province based on 3S technology / 中草药

Objective: Looking for the suitable areas of Lamiophlomis rotata based on 3S technology in Sichuan province to provide the basis for reasonable exploitation and protection of the L. rotata resource. Methods: By the ways of field researching and reviewing the related literature on L. rotata, to confirm its habitat characteristics. RS and GIS software was used to extract the environment factors such as climate, soil, topographic features, and community of L. rotata. The spatial overlay analysis on the various environmental factors were carried out to determine the distribution of L. rotata in Sichuan province. The area and combining with GPS was calculated to verify in field. Results: The result indicated that the suitable areas of L. rotata found by using 3S technology were generally consistent with the actual distribution of L. rotata. The suitable areas of L. rotata in Sichuan province were mainly distributed in 20 counties such as Aba country and Litang country. The total area of the suitable areas is about 135 200 hm2, accounting for 0.17% of the district area. Conclusion: Planting and protecting L. rotata in the suitable area will be benefit to the reasonable exploitation and protection of the L. rotata resource; This research method has the characteristics of scientificity and accuracy, which can be extended to other suitable area research of Chinese herbal medicine.

Prediction of the potential distribution of Tibetan medicinal Lycium ruthenicum in context of climate change / 中国中药杂志

To predict the suitable distribution patterns of Lycium ruthenicum in the present and future under the background of climate change, and provide reference for the resources sustainable utilization and GAP standardized planting. The software of Maxent and ArcGis was used to predict the potential suitable regions and grades of L. ruthenicum in China based on the 149 distribution information, climate data of contemporary (1950-2000) and future (20-80 decade of 21 century), and considering of three greenhouse gaseous emission scenario. The results showed that：the suitable distribution regions of L. ruthenicum are mainly concentrated in Xinjiang, Qinghai, Gansu, Neimenggu, and Ningxia province in present. In addition, Shaanxi, Shanxi and Xizang are also distribution regions.The suitable distribution area of L. ruthenicum is 284.506 949×104 km2, accounted for 29.6% of the land area of China.The relatively stable area of the suitable regions accounted for 25.2% of the total suitable region area.Under the background of climate change, compared with contemporary, the total area of suitable region is reducing and moderately suitable area is increasing at different degree at the 20, 30, 40, 50, 60, 70, 80 decade of 21 century. Climate change both can change the total area of suitable regions and habitat suitability of L. ruthenicum. It could provide a strategic guidance for protection, development and utilization of L. ruthenicum though the prediction of potential suitable regions distribution of L. ruthenicum based on the mainly factor of climate change.
