Abstract
BACKGROUND The Luchuan pig is an indigenous breed from Luchuan County, China, with cultural and genetic significance. However, traditional knowledge and conservation status have not been systematically documented. METHODS Using ethnobiological methods, we surveyed 72 Luchuan pig farmers in 7 townships during 2021-2023. Semi-structured interviews and participant observation were conducted to document traditional knowledge and management practices. RESULTS The locals reported 51 plant species used as pig feed, with 30 wild species. Growth-stage-specific feeding and seasonal adjustment practices were documented. We recorded 62 ethnoveterinary plant uses, mainly for treating pigs' heat stress and skin conditions. Luchuan pigs play central roles in local Hakka customs, rituals, and cuisine. Additonally, the new ecological farming models minimize the environmental impacts to the local community. However, there are still some challenges remained for conserving and promoting Luchuan pigs. CONCLUSIONS The Luchuan Hakka people possess rich traditional knowledge and management experience in raising Luchuan pigs. Our study provides extensive documentation of traditional knowledge and recommends integrating cultural and genetic aspects for sustaining this biocultural heritage. Findings can inform initiatives supporting local breed conservation globally.

Abstract
BACKGROUNDS Guangxi Fangcheng Golden Camellias national nature reserve, situated in Fangcheng City, Guangxi Province, China, is a coastal region renowned for its exceptional natural environment. Over time, the residents of this area have acquired extensive knowledge regarding medicinal plants, owing to their close association with the abundant flora. Our study aims to document the medicinal plants used by the local community near the Guangxi Fangcheng Golden Camellias national nature reserve. We seek to investigate the unique regional properties, cultural significance, and potential connections between medicinal plants used in surrounding villages and those sold in markets. METHODS During 2019-2021, 96 informants, including 36 key informants, were interviewed in the study area. The snowball sampling method was used to select respondents from medicinal markets and villages. Local therapists were defaulted as key informants. A panel discussion was held on the protection and threat of medicinal plants and traditional knowledge. In this study, two quantitative indicators, relative frequency citation (RFC) and informant consensus factor (ICF), were used to analyze the traditional medicinal plants in the study area. RESULTS According to the investigation, a total of 396 species of medicinal plants belonging to 295 genera and 116 families were recorded. From the perspective of Lifeform, herbs accounted for 38.9%, followed by shrubs. Most of the medicinal parts are whole plant (120 species, 25.59%), branches and leaves (116 species, 24.73%), and roots (101 species, 21.54%). Medicinal bath is the most commonly used therapeutic method. Among the 13 therapeutic targets recorded, rheumatic drugs accounted for the highest proportion, followed by muscular system diseases and skin-related diseases, which are closely related to local climate and livelihood. ICF shows that the use of local medicinal plants and related knowledge is very diverse, so local people have more options for treating diseases. Melicope pteleifolia, Clerodendrum cyrtophyllum, Lygodium flexuosum, Elephantopus scaber, Artemisia argyi, Plantago asiatica, Centella asiatica, Grangea maderaspatana, and Liquidambar formosana have high RFC, which are closely connected to local people's daily lives and are potentially vital to them. The wild vegetation, mostly around the nature reserve, is the primary source of medicinal materials sold in the urban medicinal market. Urban areas have fewer varieties of medicinal plants compared to villages near protected areas. However, there is consistency in their usage and application. CONCLUSION The medicinal plants used in the villages near the Golden Camellia Nature Reserve are diverse, and the relevant traditional knowledge is relatively well preserved. The collection of medicinal materials by local people is sustainable. This study suggests that the local government should also protect relevant traditional knowledge in the decision-making process.

Abstract
Complete mesocolic excision (CME) and D3 resection of right colon cancer have been widely implemented, but the definition and identification of the completeness of the mesentery have not been fully agreed, especially the dorsal and medial borders. In this paper, we proposed the dorsal fascia of the colonic mesentery as the dorsal border of the mesocolon and the line connecting the roots of the ileocolic artery and the middle colic artery (ICA-MCA line) as the medial border of the CME by systematically studying the relationship between the mesentery and the mesenteric bed from the theory of membrane anatomy, combined with surgical experience and in-depth review of ontogenetic anatomy. We also proposed the visible "superior mesenteric vein notch" and "middle colic artery triangle" on surgical specimens as identifiers of mesocolic completeness.

Abstract
BACKGROUND Pu'er Traditional Tea Agroecosystem is one of the projects included in the United Nations' Globally Important Agricultural Heritage Systems (GIAHS) since 2012. Against the background of having rich biodiversity and a long history of tea culture, the ancient tea trees in Pu'er have experienced from wild-transition-cultivation for thousands of years, and the local people's knowledge about the management of ancient teagardens has not been rigorously recorded. For this reason, it is important to study and record the traditional management knowledge of Pu'er ancient teagardens and the influence on the formation of tea trees and communities. This study focuses on the traditional management knowledge of ancient teagardens in Jingmai Mountains, Pu'er, and monoculture teagardens (monoculture and intensively managed planting base for tea cultivation) were used as the control, through the community structure, composition and biodiversity of ancient teagardens to respond to the influence of traditional management, and this work with a view to providing a reference for further research on the stability and sustainable development of tea agroecosystem. METHODS From 2021 to 2022, information on traditional management of ancient teagardens was obtained through semi-structured interviews with 93 local people in the Jingmai Mountains area of Pu'er. Informed consent was obtained from each participant before conducting the interview process. The communities, tea trees and biodiversity of Jingmai Mountains ancient teagardens (JMATGs) and monoculture teagardens (MTGs) were examined through field surveys, measurements and biodiversity survey methods. The Shannon-Weiner (H), Pielou (E) and Margalef (M) indices were calculated for the biodiversity of the teagardens within the unit sample, using monoculture teagardens as a control. RESULTS The tea tree morphology, community structure and composition of Pu'er ancient teagardens are significantly different from those of monoculture teagardens, and the biodiversity is significantly higher than that of monoculture teagardens. The local people mainly manage the ancient tea trees mainly using several methods, including weeding (96.8%), pruning (48.4%) and pest control (33.3%). The pest control mainly relies on the removal of diseased branches. JMATGs annual gross output is approximately 6.5 times that of MTGs. The traditional management of ancient teagardens is through setting up forest isolation zones as protected areas, planting tea trees in the understory on the sunny side, keeping tea trees 1.5-7 m apart, as well as consciously protecting forest animals such as spiders, birds and bees, and reasonably rearing livestock in the teagardens. CONCLUSIONS This study shows that local people have rich traditional knowledge and experience in the management of ancient teagardens in Pu'er, and that this traditional management knowledge has impacted the growth of ancient tea trees, enriched the structure and composition of tea plantation communities and actively protected the biodiversity within ancient teagardens.

Abstract
The Hakka people, a branch of the Han nationality with their own language, culture, and customs, are one of the largest immigrant groups worldwide, primarily distributed in southern China. Bobai, a county with the largest Hakka population globally, has a thriving weaving industry that is one of the local pillar industries. This study aimed to systematically analyze the plant source, product function, and development model of Bobai Hakka weaving. The study recorded 33 plant species for weaving, which belonged to 17 families and 27 genera. The weaving plants were mainly bamboo, rattan, grass, and wood, with herbs being the most commonly used (15 species, 45.5%). Most weaving plants were obtained locally (16 species, 41.0%) and from wild sources (13 species, 33.3%). Stems were the most commonly used plant parts (66.7%) in local weaving, followed by leaf sheaths, inflorescence stems, leaves, stem bark, leaf rachis, and female bracts. Additionally, wastes from crops such as wheat, rice, bananas, and corn, as well as invasive water hyacinths, were widely used as weaving materials by the local Hakka people. The products' functions ranged from household appliances, cultural and entertainment products, furniture, to production tools, reflecting a range of conventional cultural connotations. The study found that the Bobai Hakka weaving industry had integrated modern elements and additional use value to expand its market appeal. With the participation of the government, enterprises, and farmers, the Bobai weaving industry has formed a development model of "intangible cultural heritage + industry + poverty alleviation," which has become a successful case of poverty alleviation and rural revitalization.

Abstract
The Baiku Yao community in China has traditionally used the Lindera pulcherrima var. attenuate (LPA) leaves as a staple food source, diverging from the common reliance on grains and plant roots worldwide. This study comprehensively analyzes LPA's nutritional composition and local usage practices through field observations and laboratory testing. Our results show that LPA contains significant levels of starch, protein, and dietary fiber and is rich in trace elements, vitamin E, and flavonoids. These findings not only support the community's traditional knowledge of LPA as a valuable food and feed source but also highlight its potential as a sustainable and innovative ingredient for new food and feed products. By filling a gap in our scientific understanding of LPA, this study may contribute to developing novel and eco-friendly agricultural practices and promote regional economic growth.

Abstract
BACKGROUND Baiku Yao is an ancient branch of the Yao people in China who have the custom of maintaining homegardens. The local government has relocated some villagers to improve their livelihood. To study the characteristics of Baiku Yao homegardens and the impact of relocation, we conducted an ethnobotanical study on homegardens in the relocated villages of Huaili and Yaozhai and in the ancient villages of Yaoshan and Duonu from January 2019 to May 2022. METHOD Data on homegarden plants were collected through semi-structured interviews with homegarden households. A total of 4 villages (i.e., two relocated and two ancient villages) were selected for detailed investigation. In each village, 60 homegardens were chosen randomly. In addition, the RFC index and Jaccard value were used to analyze and evaluate the homegarden plants we recorded. RESULT The study recorded a total of 213 species of homegarden plants with approximately 11 functions. Baiku Yao homegardens are small in size but rich in species and functions, and their utilization efficiency is extremely high. The Jaccard value shows that the homegarden plants in Huaili and Yaozhai have the highest similarity. Neighborhood sharing and market purchasing are the two most important sources of local homegarden plants. Additionally, medicine and food are the two most important uses of homegarden plants. Ornamental plants also play a significant part, especially in relocated villages. The comparisons indicate that the diversity of homegarden plants in the investigated ancient villages is better preserved than in relocated villages. Due to frequent exchanges between the villages and the outside world, Yaoshan Village, as an older relocated village, maintains a good traditional culture in its homegardens. As a newly relocated village, Duonu Community has developed a complicated homegarden system with only much less plant diversity. The development of local tourism has also impacted the composition of homegarden plants. The study found that plants such as Zea mays, Morus alba, and Capsicum annuum are closely related to local life and livelihood. CONCLUSION The traditional knowledge of homegarden plants in investigated ancient villiages maintained good diversity and has been affected much less by the modernization and tourism industry development compared to the relocated villages. The composition of homegarden plants is closely connected to the local livelihood. In the future development of Baiku Yao communities, protecting homegarden plant diversity and functional diversity is crucial.

Abstract
OBJECTIVE To explore the relationship between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) level and the risk of acute ischemic stroke (AIS) recurrence in hypertensive patients. METHODS This retrospective case-control study was conducted among 211 hypertensive patients with AIS treated in Foshan First People's Hospital, including 35 patients with recurrence of AIS during the 1-year follow-up as confirmed by head CT/MR. In the overall patients, 60 had grade 1 hypertension (including 5 recurrent cases), 76 had grade 2 hypertension (with 11 recurrent cases), and 75 had grade 3 hypertension (with 19 recurrent cases). Univariate analysis, multivariate logistic regression analysis, trend analysis, and smooth curve fitting analysis were performed to explore the correlation between serum Lp-PLA2 level within 24 h after admission and the risk of AIS recurrence. The predictive efficacy of serum Lp-PLA2 level for AIS recurrence in different hypertension grades was evaluated using ROC curve analysis. RESULTS Serum Lp-PLA2 level, age, NIHSS score at admission, mRS scores at 7 days, homocysteine level and smoking status differed significantly between patients with and without AIS recurrence (P < 0.05). After adjustment for confounding factors, multivariate regression analysis showed that the highest tertile of Lp-PLA2 level was associated with a 4.13-fold increase of AIS recurrence risk compared with the lowest tertile (OR=5.13, 95% CI: 1.35-19.40), and each 1 ng/mL increase of Lp-PLA2 level was associated with a 1% increase of AIS recurrence risk (OR= 1.01, 95% CI: 1.01-1.02). Serum Lp-PLA2 level was shown to positively correlate with AIS recurrence risk, and in patients with grade 3 hypertension, its areas under the ROC curve for predicting AIS recurrence was 0.869 with a specificity of 0.893 and a sensitivity of 0.737. CONCLUSION Serum Lp-PLA2 concentration is an independent risk factor and potentially an effective predictor for AIS recurrence in patients with grade 3 hypertension.

Abstract
PURPOSE Graves' orbitopathy (GO) is an autoimmune orbital disorder. Gut microbiota dysfunction plays a vital role in autoimmune diseases, including Graves' disease (GD) and GO. In the present study, we aimed to investigate the change of gut microbiota in GD/GO using mouse model. METHODS The murine model of GD/GO was established by the challenge of adenovirus expressing thyroid-stimulating hormone (TSH) receptor (TSHR) (Ad-TSHR). The histological changes of orbital and thyroid tissues were analyzed by hematoxylin and eosin (H&E), Masson staining, and immunohistochemistry (IHC) staining. The fecal samples were collected for 16S rRNA gene sequencing and bioinformatics analysis. RESULTS The GD/GO model was established successfully, as manifested as the broadened eyelid, exophthalmia and conjunctive redness, severe inflammatory infiltration among thyroid glands and between extraocular muscle space, hypertrophic extraocular muscles, elevated thyroxine (T4) and decreased TSH, and positive CD34, CD40, collagen I, and α-SMA staining. A total of 222 operational taxonomic units (OUTs) were overlapped between mice in the Ad-NC and Ad-TSHR groups. The microbial composition of the samples in the two groups was mainly Bacteroidia and Clostridia, and the Ad-NC group had a significantly lower content of Bacteroidia and higher content of Clostridia. KEGG orthology analysis results revealed differences in dehydrogenase, aspartic acid, bile acid, chalcone synthase, acetyltransferase, glutamylcyclotransferase, glycogenin, and 1-phosphatidylinositol-4-phosphate 5-kinase between two groups; enzyme commission (EC) analysis results revealed differences in several dehydrogenase, oxidase, thioxy/reductase between two groups; MetaCyc pathways analysis results revealed differences in isoleucine degradation, oxidation of C1 compounds, tricarboxylic acid (TCA) cycle IV, taurine degradation, and biosynthesis of paromamine, heme, colonic acid building blocks, butanediol, lysine/threonine/methionine, and histidine/purine/pyrimidine between two groups. CONCLUSION This study induced a mouse model of GD/GO by Ad-TSHR challenge, and gut microbiota characteristics were identified in the GD/GO mice. The Bacteroidia and Clostridia abundance was changed in the GD/GO mice. These findings may lay a solid experimental foundation for developing personalized treatment regimens for GD patients according to the individual gut microbiota. Given the potential impact of regional differences on intestinal microbiota, this study in China may provide a reference for the global overview of the gut-thyroid axis hypothesis.

Abstract
In this study, the data of pediatric diarrhea clinic of Gansu Provincial Maternal and Child Health Hospital from January 1, 2014 to December 31, 2018 and Tianshui First Hospital from January 1, 2015 to December 31, 2018 were collected. Standardized precipitation index (SPI) and meteorological drought composite index (MCI) were used as drought indicators. Quasi-Poisson generalized additive model was used to analyze the correlation between drought and pediatric diarrhea outpatient visits. During the study period, the dry days in Lanzhou city and Tianshui city were 298 and 379 days according to SPI-1, 303 and 398 days according to MCI, respectively. There were 57 147 and 18 703 cases of diarrhea in children aged 0-6 years in Gansu Provincial Maternal and Child Health Hospital and Tianshui First Hospital, respectively. MCI and SPI (SPI-1) based on monthly precipitation were negatively correlated with the number of pediatric diarrhea outpatients. Compared with the non-drought period, SPI-1 showed the strongest correlation between middle drought and pediatric diarrhea outpatients, with an increase of 13.4% (95%CI: 7.9%-19.3%) and 20.0% (95%CI: 12.7%-27.8%) in Lanzhou city and Tianshui city, respectively. According to MCI, the outpatients with diarrhea in Tianshui children increased by 60.5% (95%CI: 3.4%-149.0%) due to extreme drought.

Abstract
Baiku Yao is a branch of the Yao ethnic group mainly living in Guangxi and Guizhou provinces of China. They are recognized by UNESCO as an ethnic group with an intact ethnic culture. The Baiku Yao people have extensive ethnoveterinary knowledge, which they used to prevent and control various animal diseases. During the African swine fever outbreak, the livestock of the Baiku Yao community remained unaffected. We investigated ethnoveterinary knowledge among local Baiku Yao villagers. A total of 39 ethnoveterinary plant species are utilized for the treatment of various diseases. Five species, namely, Stephania kwangsiensis, Aristolochia kwangsiensis, Clerodendrum bungei, Paederia foetida, and Tetradium ruticarpum, had the highest relative frequency values. Strobilanthes cusia, Tetradium ruticarpum, and Stephania kwangsiensis are highly valued locally for treating animal plagues. The existing traditional ethnoveterinary knowledge needs to be conserved and validated scientifically.

Abstract
BACKGROUND The Hakka are a subgroup of the Han Chinese, originally from northern China and mainly living in southern China now. Over hundreds of years, the Hakka have developed their own medical practices to prevent and cure diseases, such as medicinal soup, an important characteristic of Hakka cuisine. This study aims at documenting plant taxa used to make Hakka medicinal soup, along with their associated ethnomedical knowledge. METHODS Data on Hakka soup-making plants were collected through key-informant interviews, semi-structured interviews, participatory field collection, and direct observation. The choosing of participants has followed the snowball sampling method. Herbs used for preparing medicinal soup were purchased on the local market or collected from the wild, and voucher specimens were collected and identified. The study result was also compared with published studies on soup-making plants in other parts of Guangdong province and the Hakka areas in Fujian Province of China. RESULTS Eighty-three taxa belonging to 70 genera within 38 families were listed by our informants as being used to treat 55 kinds of health problems. Most documented plants are herbaceous species, followed by shrubs and woody liana. Roots were the most frequently used plant parts for medicinal purposes, followed, in descending order, by the whole plant, rhizomes, and flowers. Most plants used to prepare medicinal soup are wild-harvested (56 species), 4 cultivated, and 23 wild harvested or cultivated. According to the comparison, 18 Hakka medicinal soup species are shown both in Fujian Province and Guangdong Province. The Hakka soup-making plants in both provinces share very similar therapeutic functions. This study helps to extend the Hakka menu in both provinces. The study comparison also showed a big difference in the herb ingredients between Guangdong Hakka medicinal soup and Cantonese slow-cooked soup. CONCLUSION Hakka medicinal soup is an important feature of the Hakka dietary culture. More studies are needed to be undertaken, especially on the efficacy and safety of this medicinal soup. Moreover, cultivation and conservation efforts are required to ensure the sustainability of the species that are used as ingredients in the soup. Consequently, further commercial development of medicinal soup should be promoted.

Abstract
Evidence suggests that periodontitis contributes to the pathogenesis of inflammatory bowel disease, including Crohn's disease and ulcerative colitis. However, few studies have examined the role of swallowing and saliva in the pathogenesis of gastrointestinal diseases. Saliva contains an enormous number of oral bacteria and is swallowed directly into the intestine. Here, we explored the influence of periodontitis salivary microbiota on colonic inflammation and possible mechanisms in dextran sulfate sodium (DSS)-induced colitis. The salivary microbiota was collected from healthy individuals and those with periodontitis and gavaged to C57BL/6 mice. Periodontitis colitis was induced by DSS for 5 d and ligature for 1 wk. The degree of colon inflammation was evaluated through hematoxylin and eosin staining, ELISA, and quantitative real-time polymerase chain reaction. Immune parameters were measured with quantitative real-time polymerase chain reaction, flow cytometry, and immunofluorescence. The gut microbiota and metabolome analyses were performed via 16S rRNA gene sequencing and liquid chromatography-mass spectrometry. Although no significant colitis-associated phenotypic changes were found under physiologic conditions, periodontitis salivary microbiota exacerbated colitis in a periodontitis colitis model after DSS induction. The immune response more closely resembled the pathology of ulcerative colitis, including aggravated macrophage M2 polarization and Th2 cell induction (T helper 2). Inflammatory bowel disease-associated microbiota, such as Blautia, Helicobacter, and Ruminococcus, were changed in DSS-induced colitis after periodontitis salivary microbiota gavage. Periodontitis salivary microbiota decreased unsaturated fatty acid levels and increased arachidonic acid metabolism in DSS-induced colitis, which was positively correlated with Aerococcus and Ruminococcus, suggesting the key role of these metabolic events and microbes in the exacerbating effect of periodontitis salivary microbiota on experimental colitis. Our study demonstrated that periodontitis contributes to the pathogenesis of colitis through the swallowing of salivary microbiota, confirming the role of periodontitis in systemic disease and providing new insights into the etiology of gastrointestinal inflammatory diseases.

Abstract
Like other solid tumors, colon cancer surgery has undergone a century-old journey from lumpectomy to organ resection and then to lymphadenectomy. From the Toldt fascia to complete mesenteric resection, and from local resection to D3 radical treatment, local recurrence rates have been reduced, but remain a nuisance to surgeons and patients. Based on the theory of membrane anatomy, radical surgery for colon cancer will focus more on removing the mesocolon from the mesentery bed while maintaining the integrity of the posterior fascia to avoid the occurrence of "fifth metastasis" as much as possible. Thanks to the membrane anatomy theory, its strong reproducibility and replicability, a new phase of colorectal surgery is on the horizon.

Abstract
Ozone (O3) is a criteria air pollutant known to increase the morbidity and mortality of cardiopulmonary diseases. This occurs through a pulmonary inflammatory response characterized by increased recruitment of immune cells into the airspace, pro-inflammatory cytokines, and pro-inflammatory lipid mediators. Recent evidence has demonstrated sex-dependent differences in the O3-induced pulmonary inflammatory response. However, it is unknown if this dimorphic response is evident in pulmonary lipid mediator metabolism. We hypothesized that there are sex-dependent differences in lipid mediator production following acute O3 exposure. Male and female C57BL/6J mice were exposed to 1 part per million O3 for 3 hours and were necropsied at 6 or 24 hours following exposure. Lung lavage was collected for cell differential and total protein analysis, and lung tissue was collected for mRNA analysis, metabololipidomics, and immunohistochemistry. Compared to males, O3-exposed female mice had increases in airspace neutrophilia, neutrophil chemokine mRNA, pro-inflammatory eicosanoids such as prostaglandin E2, and specialized pro-resolving mediators (SPMs) such as resolvin D5 in lung tissue. Likewise, precursor fatty acids (arachidonic and docosahexaenoic acid; DHA) were increased in female lung tissue following O3 exposure compared to males. Experiments with ovariectomized females revealed that loss of ovarian hormones exacerbates pulmonary inflammation and injury. However, eicosanoid and SPM production were not altered by ovariectomy despite depleted pulmonary DHA concentrations. Taken together, these data indicate that O3 drives an increased pulmonary inflammatory and bioactive lipid mediator response in females. Furthermore, ovariectomy increases susceptibility to O3-induced pulmonary inflammation and injury, as well as decreases pulmonary DHA concentrations.

Abstract
Previous studies have shown that high-fat diet (HFD) may aggravate periodontitis, however the underlining mechanism remains to be further clarified. This study aims to explore whether HFD promotes periodontitis by inducing periodontal microbiota dysbiosis or stem cell dysfunction. A high-fat diet was given to four-week-old male Sprague-Dawley rats for 12 weeks. Periodontitis was induced during the latter 4 weeks. At the end of the 12th week, samples were collected after euthanasia. Maxillae were harvested for histological or microbial analysis. The microbial 16S rRNA gene sequencing was performed with the Illumina MiSeq platform. The data was analyzed through RDP Classifier against the SILVA database. The mandible molars were harvested for isolating periodontal ligament stem cells (PDLSCs). The protein level of p27, p21, and p16, which are negative regulators of the cell cycle, in PDLSCs were detected. Markers of osteogenic differentiation and pro-inflammatory mediators were detected by real-time polymerase chain reaction. Activation of pro-inflammatory signaling pathways was detected by Western blotting. We found that HFD significantly increased ligature-induced alveolar bone loss. HFD resulted in a less diverse periodontal microbiota, with increased proportions of Lactococcus, Bacillus, Alloprevotella, Carnobacterium, and Exiguobacterium and decreased proportion of Nitrospira. HFD increased the protein levels of p27, p16, and p21, and upregulated the expression of osteogenic biomarkers, IL-1β and IL-10 with the ERK1/2 signaling pathway activated in PDLSCs.

Abstract
OBJECTIVE In this study, the regulatory mechanism of miR-22-3p/AKT3 in the development of Wilms' tumor (WT) was investigated. PATIENTS AND METHODS Twenty-seven pairs of surgical tumor specimens and adjacent normal tissues were obtained from Jining No. 1 People's Hospital. The expression level of miR-22-3p in WT tissues and cell lines was measured by quantitative RT-PCR. MTT and transwell assays were performed to analyze cell proliferation and invasion in WT. The relationship between miR-22-3p and AKT3 was verified by a Dual-Luciferase assay. The protein expression of AKT3 was evaluated by Western blotting analysis. RESULTS MiR-22-3p was downregulated and AKT3 was upregulated in WT. Functionally, overexpression of miR-22-3p inhibited cell proliferation and invasion in WT. Moreover, miR-22-3p directly targets AKT3. The knockdown of AKT3 suppressed cell proliferation and invasion in WT. In addition, upregulation of AKT3 restored the tumor suppressive effect of miR-22-3p in WT. CONCLUSIONS MiR-22-3p inhibits the proliferation and invasion of WT cells by downregulating AKT3, indicating that miR-22-3p may be developed as a new biomarker for the diagnosis of WT.

Abstract
Gaultheria longibracteolata (Ericaceae) has been traditionally used by different linguistic groups in Yunnan Province, China, but it has not been well studied. Through our ethnobotanical study in Lüchun County of Yunnan, we found that this species has multiple traditional uses including food, medicine, and worship. The essential oils from the root, stem, and leaf were investigated by both GC-MS and anti-bacterial assays. The GC-MS study showed that methyl salicylate is the main (>90%) component of the essential oil, and the oil composition extracted from different plant parts showed some similarities. The oil of G. longibracteolata displayed antimicrobial activity against Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus, which is likely due to its methyl salicylate content. Gautheria longbracteolata appears to be a useful natural wintergreen oil substitute, but further studies are needed to develop this product.

Abstract
BACKGROUND Salar is a Turkic-speaking Islamic ethnic group in China living mainly in Xunhua Salar Autonomous County (Xunhua or Xunhua County), Qinghai-Tibet Plateau. Salar people are skilled in horticulture and their homegarden (HG) management. They are regarded as the first people on the Qinghai-Tibet Plateau to practice horticulture, especially manage their HGs, traditional farming systems, and supplementary food production systems. Traditional knowledge of Salar people associated with their HGs always contributes significantly to the local livelihood, food security, ornamental value, and biodiversity conservation. The cultivation of different plants in HGs for self-sufficiency has a long tradition in China's rural areas, especially in some mountainous areas. However, Salar traditional HGs have not been described. The present paper aims to report the features of Salar HGs mostly based on agrobiodiversity and its ecosystem services. METHODS The methods used in this work included semi-structured interviews and participatory observation. A total of 60 households in three townships, 9 villages were surveyed. There are 4-12 family members in each household, aged from 20 to 86 years old. The homestead size is between 200 and 1200 m2. Plant species cultivated in Salar HGs were identified according to Flora of China. Based on a comprehensive survey of Salar HGs and related to background data, we identified and characterized the most important services and functions provided by Salar HGs. RESULTS According to primary production systems, there are 4 different types of Salar HGs, including ornamental focus, product focus, dual-purpose and multi-purpose. In total, 108 (excluding weeds and bonsai) plant species were recorded in Salar HGs, within 43 plant families. The most important and frequently used plants are Rosa chinensis, Armeniaca vulgar, Prunus salicina, and Ziziphus jujuba. About 4 to 32 plant species were recorded in each homegarden. We found that the Salar HGs, as a typical agroecosyste, prossess multiple servcices and functions that directly benefit households according to the field investigation. CONCLUSION This paper reveals the floristic diversity of Salar HGs. It presents useful information in the homegarden agroecosystem of Salar people, such as HG types and species diversity in Salar HGs. Ecosystem functions and services research suggested that the Salar HG agroecosystem provides agroecosystem services mainly related to supply and culture services. Salar HGs are important as food supplement resources, aesthetics symbol, and cultural spaces.

Abstract
Three new xanthone glycosides, canlucosides A - C (1 - 3), along with three known compounds (4 - 6), have been obtained and identified from the ethanol extract of Canscora lucidissima. Their structures were identified according to HR-ESI-MS, 1D, 2D NMR data, ECD measurements powered by molecular calculations and optical rotation values. Compound 6 (1-hydroxy-3,7,8-trmethoxyxanthone) was isolated from C. lucidissima for the first time. Five compounds (2-6) showed moderate antioxidant and NO inhibitory activities. Canlucosides B and C (2 and 3) showed significant antioxidant activity with IC50 values of 33.64 ± 5.60 µM and 36.63 ± 4.32 µM, respectively. Canlucoside B (2) possessed a significant NO inhibitory effect with an IC50 value 0.92 µM.

Abstract
OBJECTIVE To investigate the effects of long non-coding ribonucleic acid (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on myocardial ischemia/reperfusion (I/R) injury in rats and its mechanism, and to provide a certain reference for the clinical prevention and treatment of myocardial infarction. MATERIALS AND METHODS A total of 60 male Sprague-Dawley rats were divided into 3 groups using a random number table, including the Sham group (n=20), I/R group (n=20) and I/R + MALAT1 small interfering RNA (siRNA) group (n=20). An I/R model was established by means of recanalization after ligation of the left anterior descending coronary artery of the rats. The rats in the I/R + MALAT1 siRNA group were used to establish a model of MALAT1 knockdown by injecting MALAT1 siRNA from the tail vein. The myocardial infarction area in each group was detected via 2,3,5-triphenyl tetrazolium chloride (TTC) staining. The ejection fraction% (EF%) and fractional shortening% (FS%) of the heart in each group were measured through echocardiography. Hematoxylin and eosin (H&E) staining was adopted to determine the morphological changes in myocardial cells in each group. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining was performed to detect the apoptosis levels of myocardial cells and fibroblasts in the cardiac tissues in each group, and Western blotting assay was conducted to measure the expression levels of apoptosis-related proteins [B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax)]. In addition, the content of β-catenin in the three groups of rats was determined via immunohistochemical staining. Finally, the impacts of MALAT1 siRNA on the expression level of β-catenin protein were detected using Western blotting assay. RESULTS MALAT1 siRNA could prominently ameliorate the I/R-induced cardiac insufficiency in the rats and improve the EF% and FS% of the heart (p<0.05). Moreover, MALAT1 siRNA was able to remarkably inhibit the I/R injury-induced myocardial infarction, reducing the infarction area from (59.54±3.45) to (24.85±1.30; p<0.05). The results of the H&E staining indicated that compared with those in the I/R group, the myofilaments of the myocardial cells were well-arranged, the degrees of degradation and necrosis of the myofilaments declined, and the cellular edema was relieved markedly in the I/R + MALAT1 siRNA group. It was shown in the results of immunohistochemistry and Western blotting that MALAT1 siRNA could notably reverse the I/R-induced up-regulation of β-catenin expression (p<0.05). CONCLUSIONS MALAT1 knockdown can significantly ameliorate the I/R-induced myocardial injury and improve the cardiac function of the rats, whose mechanism is probably correlated with the inhibition of MALAT1 siRNA on β-catenin. Therefore, MALAT1 siRNA is expected to become a new target for the treatment of myocardial infarction.

Abstract
BACKGROUND Traditional bamboo weaving has been practiced for centuries in Sansui, a county dominated by the Miao people, in Guizhou province of Southwest China. Sansui bamboo weaving represents an intangible cultural heritage as defined by UNESCO, but, like many other traditional handicrafts in China, it has suffered a downfall in this period of rapid development. Sansui bamboo weaving is now experiencing a renaissance due to the joint efforts of the local government, bamboo weaving companies, and individual bamboo weavers. However, what bamboo species have supported the traditional bamboo weaving in Sansui keeps unknown up to now. The traditional knowledge and technology associated with bamboo weaving have not been reported. In addition, the resumption of the local bamboo industry may provide some valuable experiences for other downfallen traditional handicrafts or local communities. Thus, an ethnobotanical study on Sansui bamboo weaving has been carried out. METHODS This study mainly used ethnobotanical methods, including key informant interviews and participatory observations. Different stakeholders were selected by applying the snowball method as our key informants including 6 officials, 37 bamboo weavers, and 17 bamboo and bamboo weaving product merchants. We also went into the local weavers' houses to visit the whole weaving process. The bamboo and dye plant species for bamboo weaving were identified by taxonomists and referring to online databases available. RESULTS Based on field investigations, 17 bamboo species used for weaving were recorded. Different bamboo species were woven for different purposes based on their own characters. Phyllostachys heteroclada is the most popular species locally. Bamboo strips are usually dyed by using Platycarya strobilacea and Rubia cordifolia to be made for different images. In recent years, the size, functions, and materials of local bamboo weaving crafts as well as their market mode have been changed to adapt to new development trends and to cater to the market. In addition, the cooperation among bamboo weavers, bamboo companies, and household workshops has provided great support to the local bamboo industry and to reboot the economy of the local community. Some suggestions for the sustainable economic development of Sansui bamboo weaving and other Chinese traditional handicrafts are proposed. CONCLUSION In the present study, the bamboo weaving-associated traditional knowledge was collected by means of ethnobotanical methods. The recent renaissance of the bamboo weaving business in Sansui can be attributed both to government support and the innovations of the bamboo weaving industry itself. The developing mode ("Internet + intangible cultural heritage + poverty alleviation"), which combined the internet, poverty alleviation, and intangible cultural heritage, is valid and worth being promoted.

Abstract
BACKGROUND The Dulong (Drung) people have used plant materials in traditional beekeeping for many decades. However, there are few studies on the plants used in traditional beekeeping. Furthermore, traditional ecological knowledge (TEK) associated with beekeeping is still poorly understood. TEK and plants associated with beekeeping play an important role in the conservation of native bees and the development of beekeeping. It is therefore very urgent to investigate, record, and study the plants and TEK of Dulong beekeeping. METHODS Fieldwork was conducted in the Dulong community of Gongshan County, Yunnan Province, China. Six Dulong villages were investigated. Ethnobotanical methods such as free listing, semi-structured interviews, participatory observation, and key informant interviews were used to collect data. A total of 42 Dulong respondents provided information about plants used in traditional beekeeping. TEK related to traditional beekeeping plants was documented. Citation frequency, abundance, and preference ranking of log beehive plant species were used to identify plant resources that are "easier to obtain" and "more preferred." RESULTS There are two general methods of traditional Dulong beekeeping: living tree beekeeping and log beehive beekeeping. The investigation revealed that 38 species (in 19 families), including 30 tree species, 5 bamboo species, 2 herbaceous species, and 1 liana species, are used in traditional Dulong beekeeping. Different plant parts are used for different purposes. Twenty-seven tree species are used to make log beehives. Species from the family Pinaceae and Fagaceae are the most frequently represented. Seven of the most commonly reported species used to build log beehives were scored by ten beekeepers. Based on this scoring, the beekeepers' most preferred species for making log beehives are Alnus nepalensis, Pinus yunnanensis, and Juglans regia. CONCLUSION The Dulong people have used various plants for traditional beekeeping and have accumulated rich TEK associated with apiculture. Future research will include a nutritive components analysis of honey from traditional Dulong beekeeping and an ethnobotanical investigation of melliferous species used in traditional Dulong apicultural systems. The application of plants and TEK associated with beekeeping is important for improving livelihoods in local communities, conserving biocultural diversity, and protecting the eco-environment of the Dulongjiang area.

Abstract
OBJECTIVE To explore whether microRNA-579-3P was involved in the development of osteoporosis, and to investigate the possible molecular mechanisms. PATIENTS AND METHODS The messenger RNA (mRNA) expression levels of microRNA-579-3P, alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX2) and bone sialoprotein (BSP) in serum samples of osteoporosis patients and normal controls were detected by quantitative Real-time polymerase chain reaction (qRT-PCR), respectively. Meanwhile, the expressions of the above genes during osteogenic differentiation of human bone marrow mesenchymal stem cells (hMSCs) were examined as well. To investigate the effect of microRNA-579-3P on osteogenesis, microRNA-579-3P was overexpressed and knocked down in hMSCs. Subsequently, the mRNA and protein expression levels of osteogenesis-related genes, such as ALP, RUNX2 and BSP, were detected by qRT-PCR and Western blot, respectively. In addition, ALP activity and mineralization forming ability were evaluated by ALP staining and alizarin red staining. Bioinformatics predicted that Sirt1 was the target gene of microRNA-579-3P. Subsequent luciferase reporter gene assay was performed to verify the binding relationship of microRNA-579-3P to Sirt1. Meanwhile, qRT-PCR and Western blot were used to detect the changes in the mRNA and protein expression levels of Sirt1, respectively. After overexpression of microRNA-579-3P and Sirt1, qRT-PCR, Western blot, ALP staining and alizarin red staining assays were performed to detect the osteogenic differentiation of hMSCs. RESULTS The expression of microRNA-579-3P in serum of patients with osteoporosis was significantly higher than that of normal controls. Meanwhile, the expression of microRNA-579-3P decreased gradually during osteogenic differentiation of hMSCs. Overexpression of microRNA-579-3P significantly reduced the expressions of osteogenic related genes, including ALP, RUNX2 and BSP. Besides, ALP activity and mineralized nodule formation ability decreased obviously as well. Luciferase reporter gene assay showed that microRNA-579-3P could bind to Sirt1. After overexpression of microRNA-579-3P, the mRNA and protein expression levels of Sirt1 were significantly reduced, which were reversed after silence of microRNA-579-3P. Simultaneous overexpression of microRNA-579-3P and Sirt1 could reverse the inhibition of osteogenic differentiation of hMSCs caused by overexpression of microRNA-579-3P alone. CONCLUSIONS MicroRNA-579-3P could inhibit osteogenic differentiation of hMSCs by regulating Sirt1, thereby promoting the development of osteoporosis.

Abstract
Fermented foods have unique microbiota and metabolomic profiles that can support dietary diversity, digestion, and gut health of consumers. Laowo ham (LWH) is an example of an indigenous fermented food from Southwestern China that has cultural, ecological, economic, and health significance to local communities. We carried out ethnobiological surveys coupled with metagenomic and metabolomic analyses using GC-TOF-MS and UPLC-QTOF-MS to elucidate the microbiota and metabolic profiles of LWH samples at different ripening stages. The results from high-throughput sequencing showed a total of 502 bacterial genera in LWH samples with 12 genera of bacteria and 6 genera of fungi identified as dominant groups. This is the first study to our knowledge to report the bacteria of Lentibacillus and Mesorhizobium along with fungi Eremascus and Xerochrysium on a fermented meat product. Findings further revealed that the metabolite profiles among LWH samples were significantly different. In total, 27 and 30 metabolites from GC-TOF-MS and UPLC-QTOF-MS analysis, respectively, were annotated as highly discriminative metabolites. Among the differential compounds, the relative contents of most amino acids showed the highest in the LWH sample ripened for two years, while some metabolites with potential therapeutic effects such as levetiracetam were the most abundant in the LWH sample ripened for three years. The correlation analysis indicated that the dominant microbes were closely related to differential metabolites, highlighting the importance of their functional characterization. Findings indicate that the consumption of LWH contributes to microbiological and chemical diversity of human diets as well as suggests efficacy of combining GC-MS and LC-MS to study the metabolites in dry-cured meat products.

Abstract
Plants in Acorus have been used as herbal medicine by various linguistic groups for thousands of years. Arguments of taxonomy of Acorus among scientists resulted in confusions and misuses of Acorus plants. The present study used different methods to investigate the classification of the genus, based on folk taxonomy. The relationships among Acorus species were revealed through phylogenetic analyses by constructing the Maximum Likelihood and Bayesian phylogenetic analyses based on sequences of two chloroplast regions (trnL-trnF and rbcL). All samples named with two so-called synonyms, Acorus macrospadiceus (Yamam.) F. N. Wei and Y. K. Li and Acorus tatarinowii Schott collected from different habitats, were clustered into separate groups, which revealed that they represented two independent species. Multivariate statistical analysis of metabolites from different Acorus populations were carried out based on UPLC-QTOF-MS data. Three independent analysis, principal component analysis, heat-map analysis, and hierarchical cluster analysis, showed that A. macrospadiceus and A. tatarinowii are different from two recognized species in the genus, A. calamus L. and A. gramineus Aiton. The results of phylogenetics and chemotaxonomy, together with morphological and ecological evidences, were consistent with traditional knowledge of local people related to Acorus taxa, which proved the significance of parataxonomy. Multiple evidences including morphological, ecological, folk taxonomic, phylogenetic, and chemical taxonomic results suggested that there are four species in the genus Acorus.

Abstract
Abstract Measurement of corpse temperature is mainly used for estimation of early postmortem interval, and rectal temperature is often used as a representative of body's core temperature in actual work because it is simple, quick and non-invasive. At present, the rectal temperature postmortem interval estimation method internationally accepted and widely used is HENSSGE's nomogram method, while many domestic scholars also deduced their own regression equations through a large number of case data. Estimation of postmortem interval based on rectal temperature still needs further study. The nomogram method needs to be optimized and extended, and quantification of its influencing factors needs to be dealt with more scientifically. There is still a lack of consensus on the probability and duration of the temperature plateau. There is no clear understanding of the probability and extent of the change in initial temperature caused by various causes. New methods and ideas enrich methodological research, but it still lacks systemicity and practicality. This article reviews the researches on estimation of postmortem interval based on rectal temperature in order to summarize the current situation of previous researches and seek new breakthrough points. Because the decline of body temperature can be easily influenced by many factors in vitro and vivo, and the influencing factors in different regions vary greatly, regionalization research and application may be a practical exploration to improve the accuracy of postmortem interval determination.

Abstract
BACKGROUND Ecological migration serves as an important measure for poverty eradication as well as for the protection, inheritance, and utilization of traditional ecological knowledge. This study investigated and cataloged the traditional forage plant resources and recorded the associated traditional knowledge of immigrant villages in Hongsibu District of Ningxia, China. The diversity of traditional forage plant resources and the changes in associated traditional ecological knowledge were compared among ecological immigrant villages from different emigration areas, with a hope of providing a reference for forage development, the conservation of wild forage plant resources, and the development of regional animal husbandry. METHODS From March 2018 to May 2019, a field investigation was conducted in six villages in Ningxia. Through the snowball technique, a total of 315 immigrants were interviewed using various methods, including semistructured interviews and key person interviews, which included opportunities for free listing. The changes in the utilization of traditional forage plants were compared between the ecological migrants and the original inhabitants, and the causes underlying the changes were analyzed. In addition, the major forage plant species in the research area were investigated and evaluated. RESULTS (1) The six investigated villages reported 224 traditional forage plant species that belong to 42 families and 150 genera. Compared with their original living areas, the number of traditional forage plant species used in the immigrant villages decreased with the increase in the relocation distance. (2) The utilization of traditional forage plants varied among the immigrants who moved to Hongsibu District from forest areas, loess hilly areas, and semiarid desertified areas. The smaller the difference was in ecological environment between the immigration and emigration areas, the more the traditional forage plant knowledge had been retained. (3) The diversity and associated knowledge of traditional forage plants retained by ecological migrants are closely correlated to gender, age, education level, and occupation. CONCLUSION This study revealed that the diversity of traditional forage plants and associated knowledge retained after migration vary among ecological immigrants from different areas; generally, the immigrants that relocated from a closer place retained more ecological knowledge. In the immigrant villages with significantly different natural resources and a long distance from the migrants' original locations, the diversity of traditional forage plants decreased, and the traditional knowledge about forage plants showed signs of being forgotten and abandoned by the younger generation. Therefore, measures are urgently needed to document and protect the forage plant resources and preserve the traditional knowledge of ecological immigrants.

Abstract
BACKGROUND Zongzi, a common Chinese rice-pudding and one of the most symbolic foods in traditional Chinese festivals, is integral to both Chinese traditional culture and daily meals. Traditionally, the leaves of different plant species have been used to wrap zongzi. The variety of zongzi leaves (ZLs) can contribute to the zongzi-based cultural diversity. Given the cultural and dietary significance of zongzi, the ethnobotanical surveys were carried out, aiming to investigate the diversity of plant species and associated traditional botanical knowledge of ZLs, which could attract particular attention for their further studies. METHOD Both literature studies and field surveys were conducted in the study. The field investigations were carried out from May 2006 to June 2018 throughout China. Ethnobotanical information about ZLs was obtained by direct observation, semi-structured interviews, and key informant interviews. RESULTS In total, ZLs from 57 plant species were identified and recorded, belonging to 38 genera and 18 families. Several folk legends have been formed to explain the origin of using plant leaves to pack zongzi. Over time, Chinese people have developed diverse traditional botanical knowledge surrounding ZLs, especially regarding the zongzi flavor, antiseptic functions, and medicinal values. Based on the literature review, some species of ZLs such as the leaves of Corchorus capsularis and Vernicia fordii may even pose a potential threat to human health. Presently, in some regions of China, the traditional ZLs, such as Cocos nucifera, Tilia tuan, and Zizania latifolia, are being substituted by commercialized ZLs such as Phragmites australis and Indocalamus tessellatus. CONCLUSION A variety of traditional ZLs have been discovered in China. Although diverse traditional knowledge exists in China surrounding the usage of ZLs, some species may have the potential of threatening human health. Therefore, further explorations are necessary to comprehensively evaluate traditional ZLs, the results of which could help to conserve the cultural diversity of zongzi, to guarantee food safety, and to encourage the uses of plant leaves in food, medicine, and environmental management, for our human health.

Abstract
BACKGROUND Wild edible and medicinal plants were an important component of traditional diets and continue to contribute to food security, nutrition, and health in many communities globally. For example, the preparation and consumption of soup made of medicinal plants for promoting health and preventing disease are a key component of the traditional diets of the Hakka socio-linguistic group of China's West Fujian Province. As environmental and socio-economic factors drive the shift away from traditional diets, there is a need for ethnobotanical documentation of the diversity of wild edible and medicinal plants as well as associated knowledge and practices. METHOD Ethnobotanical surveys were conducted in Hakka communities in West Fujian Province between 2017 and 2018 to document plants used in medicinal soups as well as associated traditional ecological knowledge, practices, and conservation status. Surveys included semi-structural interviews, key informant interviews, participatory rural appraisal, and focus group discussions. Quantitative indices, including cultural food significance index (CFSI) and relative frequency of citation (RFC), were calculated to evaluate the importance of documented plants to Hakka communities. The species with the highest CFSI and RFC values were ranked by informants and further evaluated according to their individual properties and growth environment. RESULTS A total of 42 medicinal plant species, belonging to 25 families and 41 genera, were documented for making soup by the Hakka. The Asteraceae botanical family was the most prevalent, and their root or the entire plant is used for soup making. Informants incorporate different ingredients in soups for their flavors as well as medicinal properties on the basis of the local ethnonutrition system. The most prevalent medicinal uses of the documented plants for making soups were used for clearing inner heat (58.1% of the species), treating inflammation (37.2%), and counteracting cold in the body (20.9%). Informants perceived that the medicinal properties of soup-making plants are influenced by the time of harvest, the local environment, and the climate. CONCLUSION Efforts are needed to preserve the ecological knowledge associated with traditional diets towards supporting both environmental and human well-being in rapidly developing communities experiencing the nutrition transition and biodiversity loss.

Abstract
BACKGROUND The Hani people in the Honghe Prefecture of Southeastern Yunnan, China, have practiced terraced rice paddy farming for more than 1300 years. These rice fields, combined with the surrounding forests and water systems, form a special agroecosystem that has attracted both tourists and scientists. For centuries, the local people have traditionally collected wild edible plants (WEP) from the agroecosystem, but this unique traditional practice in this area has never been reported. METHODS Ethnobotanical fieldwork was conducted in four counties (Yuanyang, Honghe, Jinping, and Lüchun) between 2014 and 2019. Local self-identified Hani people (186) were interviewed, and information concerning local WEP species was obtained, documented, and analyzed. Plant samples and voucher specimens were collected for taxonomic identification. RESULTS A total of 224 WEP species, belonging to 90 families and 170 genera, were recorded as used by the Hani people in Honghe. The most common WEP parts used include fruits, stems, and leaves, and the most common preparation methods include eating as a potherb (wild vegetable) and eating fresh. Some WEPs, like Phyllanthus emblica and Dioscorea subcalva, have unique preparation methods. The use-value (UV) and frequency of utilization index (FUI) of WEP species were analyzed. The 20 WEP species with the highest UV were noted as particularly important to the Hani people's daily life in Honghe. CONCLUSION A large majority of these WEP species possess tremendous economic potential for future development. However, the diversity of WEP species, the associated traditional knowledge, and the broader agroecosystem are facing challenges such as biodiversity loss and pollution from chemical pesticides and fertilizers. This study may help local people to recognize the value of local WEP species and associated traditional knowledge, as well as provide ethnobotanical information for the future development of this tourism region.

Abstract
OBJECTIVE Perlecan, which is also called heparan sulfate proteoglycan 2 (HSPG2), is a protein encoded by the HSPG2 gene that maps to 1p36.12 in the human genome. In this study, we assessed the independent prognostic value of HSPG2 in terms of overall survival (OS) and recurrence-free survival (RFS) in patients with LGG. PATIENTS AND METHODS A retrospective study was conducted by using data in the Cancer Genome Atlas-Low Grade Glioma (TCGA-LGG). RESULTS Increased HSPG2 expression was an independent prognostic indicator of poor OS in oligoastrocytoma (HR: 1.644, 95% CI: 1.116-2.423, p = 0.012) and in oligodendroglioma (HR: 1.459, 95% CI: 1.138-1.871, p = 0.003). In addition, increased HSPG2 expression independently predicted poor RFS in oligodendroglioma (HR: 1.402, 95% CI: 1.110-1.770, p = 0.005). Furthermore, we observed that high HSPG2 expression was associated with significantly shorter OS and RFS in oligodendroglioma, no matter the patients received radiotherapy or not. Using copy number alterations (CNAs) and DNA methylation data in TCGA-LGG, we found that DNA copy deletion was generally associated with decreased HSPG2 expression. Regression analysis suggested a weak negative correlation between HSPG2 expression and HSPG2 DNA methylation (Pearson's r = -0.388). CONCLUSIONS Increased HSPG2 expression could independently predict poor OS in oligoastrocytoma and oligodendroglioma and also independently predicted poor RFS in oligodendroglioma. Its expression is modulated by both DNA copy number and DNA methylation in oligodendroglioma.

Abstract
Peroxisome proliferator activated receptor delta (PPARD) is a nuclear receptor transcription factor whose single nucleotide polymorphism (SNP), especially PPARD-87 T>C (rs2016520), may play an important role in expression regulation of PPARD. But its expression patterns as well as contribution in colorectal cancer (CRC) are still controversial. In this study, whether the intratumoral heterogeneity of polymorphism of PPARD-87 T>C (rs2016520) existed and its influence in CRC were investigated. Tumor masses from primary CRC patients were collected during the operation of tumorectomy, specimens at the different sites of the same tumor mass were sampled and stored individually. The SNP of PPARD-87 T>C was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and the expression of PPARD in vivo was observed by immunohistochemistry. The correlation of PPARD -87 T>C intratumoral polymorphism and the clinicopathological parameters of patients was analyzed statistically. Tumor samples were collected from 106 CRC patients (70 males and 36 females) with an average age of 61.04±13.67 years. A total number of 808 samples (7.60±1.60 per patient) were mainly harvested at peripheral superficial (n=376), central superficial (n=163), invasive front (n=112) and mesenteric cancer foci (n=42) of tumor tissues as well as cancerous adjacent mucosa (n=104). PCR-RFLP analysis showed that T/T (n=460, 56.9%) and T/C (n=334, 41.3%) were the main genotypes of -87 T>C among these samples. Furthermore, intratumoral genotype of -87 T>C was homogeneous in 90 patients and heterogeneous in other 16 patients. The intratumoral heterogeneity was related to patients' age (P=0.016), tumor location (P=0.011) and the grade of differentiation (P=0.022). For patients with intratumoral heterogeneity, immunochemistry showed the expressions of PPARD were not influenced by T/T or T/C genotypes. Intratumoral heterogeneity of PPARD-87 T>C wildly existed in CRC, and associated with patients' age, tumor location and differentiation. However, the immunochemistry assay revealed that there's no significant link between heterogeneity and expression of PPARD.

Abstract
Abstract Objective To discuss the methods and strategies to identify the causes of dependents' deaths, as well as provide the experiences that can be used for reference and scientific basis for the forensic identification of the potentially growing deaths of the same kind in the future. Methods The 13 cases concerning death of dependents accepted by Sun Yat-sen University Forensic Center were collected, and the basic information of the dependents were statistically described. The nutritional status, environmental condition and medical care condition were evaluated according to dietary energy, living space, environment and medical treatment condition. Results Among the 13 dependents, there were 11 males and 2 females, with the oldest 74 and the youngest 9 and dwelling time was from 0.4 to 5.6 years. Forensic pathological examination showed that 13 dependents had infectious diseases and 11 were severely dystrophic. There were no fatal mechanical injuries or poisoning in dependents. Molecular pathological screening of 4 cases revealed no pathogenic variants of sudden death susceptible genes. The poor status of the diet, nutrition, living environment and medical care of these dependents were discovered. The direct cause of death of all 13 dependents was identified to be disease. The lack of nutrition, poor living environment and lack of medical care were thought to play a dominant role in causing the deaths of 12 dependants. Conclusion The death identification should follow the judicial procedure. In identification of the causes of death and analysis of the proportion of the affecting factors resulting in death, all factors, including nutrition,environment, medical care, injury and diseases, need to be considered.

Abstract
Objective: To explore the repair methods and effects of the complex wounds on hands after burns or trauma. Methods: From January 2008 to December 2017, 45 patients (28 males and 17 females, aging 8 to 58 years) with severe hand injuries after burns or trauma combined with deep tissue exposure were admitted to our hospital. Two patients had whole-fingers degloving injuries, 27 patients had dorsal hand injuries, and 16 patients had palmar injuries. After debridement, the area of soft tissue defects was 7 cm×6 cm to 19 cm×12 cm combined with 0.5 cm×0.4 cm to 10.0 cm×4.0 cm of single deep tissue exposure. Different repairing methods were adopted according to the area and location of deep tissue exposure. Five patients with small area exposure were treated with artificial dermis+ vacuum sealing drainage (VSD)+ autogenous skin grafting. Thirty-eight patients with unilateral large area exposure on palm or dorsum were treated with segmented ligation of abdominal thin flaps (with area of 8 cm×7 cm to 15 cm×9 cm). Two patients with bilateral large area exposure in dorsal and palmar hands were treated with modified abdominal bag-shaped delayed thin flaps (with area of 12 cm×5 cm to 12 cm×9 cm and 12 cm×6 cm to 14 cm×9 cm). The donor sites were directly sutured or repaired with intermediate split-thickness skin or adjacent flap. The survival of grafts and flaps was observed, number of operations, wound healing time, and follow-up were recorded. Results: (1) Among the patients receiving artificial dermis+ VSD+ autogenous skin grafting, the wounds of 3 patients were healed after 2 operations, and 2 patients had artificial dermis infection and lysis, and tendon necrosis, which were healed after 3 operations. The wound healing time of 5 patients was 14 to 33 days post injury. During the follow-up of 3 months, the affected hands were in good shape with soft texture and fewer scars, and functional evaluation of hand was good in 3 cases and modest in 2 cases. (2) The patients receiving segmented ligation of abdominal thin flaps all underwent 2 operations without flap necrosis. The wound healing time was 2 to 3 weeks post injury. Thirty-five patients underwent one to six-years' follow-up, which showed that the flaps were in good shape and color with soft texture, and the functional evaluation of hand was excellent in 25 cases, good in 7 cases, and modest in 3 cases. Three patients were lost to follow-up. (3) In the 2 patients receiving modified abdominal bag-shaped delayed thin flaps, all flaps survived after 5 operations, the wounds were healed on post injury day 22 and 24 respectively, the shape and texture of the affected hands was good with no bloated appearance after separating fingers and revision. During the follow-up of 2 years, the functional evaluation of hand was good in 2 cases. Conclusions: For the complex wounds on hands after burns or trauma, if the area of deep tissue exposure is small, artificial dermis+ VSD+ autogenous skin grafting should be adopted, which has good effects. If the area of unilateral deep tissue exposure is large, segmented ligation of abdominal thin flap should be adopted; if the area of bilateral deep tissue exposure is large, modified abdominal bag-shaped delayed thin flap should be adopted. These methods can reduce the number of operations, shorten wound healing time, and obtain good shape and function of hands.

Abstract
Objiective: To evaluate the prognosis of visual function and the impact of surgery in pediatric patients with sellar mass lesions, as evidenced by diffusion tensor imaging (DTI) and visual evoked potentials. Methods: Twenty patients with sellar mass lesions were included in the study. DTI and visual evoked potentials were obtained before and after surgery. Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were calculated for both optic nerves. DTI parameters and visual evoked potential amplitudes were compared for all patients to assess the correlation between DTI parameters and visual function. Results: The 20 patients were divided into two groups according the relationship between the lesions and the optic chiasm. The FA values increased significantly after operation, while the ADC values decreased (P<0.05). And the average amplitude of visual evoked potentials after operation was significantly higher than before operation (P<0.05). Conclusions: DTI assessments of the affected sides, with the resulting FA and ADC values, may help to estimate the visual improvement produced by surgical therapy in the early postoperative period. Surgical removal can improve visual function dramatically.
