Effects of Potassium-Solubilizing Bacteria on Growth, Antioxidant Activity and Expression of Related Genes in Fritillaria taipaiensis P. Y. Li

This study aimed to examine the effects of inoculating Fritillaria taipaiensis P.Y.Li leaves with different strains ofpotassium-solubilizing bacteria (KSB), or combinations thereof, focusing on aspects of photosynthesis and physiologicaland biochemical characteristics. At present, some studies have only studied the rhizosphere microbialcommunity characteristics of F. taipaiensis and have not discussed the effects of different microbial species on thegrowth promotion of F. taipaiensis. This paper will start from the perspective of potassium-solubilizing bacteria toconduct an in-depth study. Seed cultivation commenced at the base with three different KSBs in early October2022. The growth of F. taipaiensis leaves was observed after different treatments. Both single-plant and compoundinoculations were executed. A total of eight treatment groups were established, with aseptic fertilizer and sterilizedsoil functioning as the control group. The results reveal that intercellular CO_(2) concentration (Ci), stomatal conductance(Gs), and transpiration rate (Tr) were at their apex in the S7 group. Most treatment groups exhibited anincrease in leaf area, photosynthetic pigment content, soluble sugar, soluble protein, Superoxide Dismutase(SOD), Peroxidase (POD), Catalase (CAT) activities, and proline content. The expression levels of POD, SOD,and CAT genes were evaluated, following inoculation with different KSB. The highest was the S7 group. Theinoculation with various KSB, or combinations thereof, appears to bolster the growth and development of F. taipaiensis.The composite inoculation group S7, comprising Bacillus cereus, Burkholderia cepacia, and Bacillus subtilis,manifested the most favorable impact on the diverse indices of F. taipaiensis, thereby furnishing valuableinsights for the selection of bacterial fertilizer in the artificial cultivation of F. taipaiensis.

Effects of Inoculation with Phosphate Solubilizing Bacteria on the Physiology,Biochemistry,and Expression of Genes Related to the Protective Enzyme System of Fritillaria taipaiensis P.Y.Li

Fritillaria taipaiensis P.Y.Li is a widely used medicinal herb in treating pulmonary diseases.In recent years,its wild resources have become scarce,and the demand for efficient artificial cultivation has significantly increased.This article is the first to apply phosphate solubilizing bacteria isolated from the rhizosphere soil of F.taipaiensis P.Y.Li to the cultivation process of F.taipaiensis P.Y.Li.The aim is to identify suitable reference strains for the artificial cultivation and industrial development of F.taipaiensis P.Y.Li by examining the effects of various phosphate solubilizing bacteria and their combinations on photosynthesis,physiological and biochemical properties,and gene expression related to the protective enzyme system in F.taipaiensis P.Y.Li.The experiment,conducted in pots at room temperature,included a control group(CK)and groups inoculated with inorganic phosphorussolubilizing bacteria:W1(Bacillus cereus),W2(Serratia plymuthica),W12(Bacillus cereus and Serratia plymuthica),and groups inoculated with organophosphorus-solubilizing bacteria:Y1(Bacillus cereus),Y2(Bacillus cereus),Y12(Bacillus cereus and Bacillus cereus),totaling seven groups.Compared to CK,most growth indices in the bacterial addition groups showed significant differences,with W12 achieving the highest values in all indices except the leaf area index.The content of photosynthetic pigments,photosynthetic parameters,and osmoregulatory substances increased variably in each bacterial treatment group.W12 exhibited the highest content of chlorophyll a and soluble protein,while W1 had the highest free proline content.The activities of peroxidase(POD),superoxide dismutase(SOD),and catalase(CAT)in all inoculated groups were higher than in CK,with significant changes in SOD and CAT activities.The malondialdehyde(MDA)content in all inoculated groups was lower than in CK,with Y12 being the lowest,at approximately 30%of CK.Gene expression corresponding to these three enzymes also increased variably,with POD expression in Y2 being the highest at 2.73 times that of CK.SOD and CAT expression in Y12 were the highest,at 1.84 and 4.39 times that of CK,respectively.These results indicate that inoculating phosphate solubilizing bacteria can enhance the growth of F.taipaiensis P.Y.Li,with the mixed inoculation groups W12 and Y12 demonstrating superior effects.This lays a theoretical foundation for selecting bacterial fertilizers in the cultivation process of F.taipaiensis P.Y.Li.

The most popular journal in the field is Diabetes Care;Fukui, Michiaki is the most prolific author, leading many studies related to diabetic sarcopenia. The most frequently cited reference was a revised European consensus on the definition and diagnosis of sarcopenia;the most cited keywords were related to physiological factors of diabetes, sarcopenia and related conditions, such as “insulin resistance”, “skeletal muscle”, “body composition”, “risk” and “prevalence”. Conclusion: With more and more studies on the relationship between diabetic sarcopenia, this study presents the current status and trend of research related to diabetic sarcopenia over the past nearly 30 years through the visualization software CiteSpace. It can help researchers identify potential collaborators and partner institutions, hotspots and research frontiers in the field of diabetic sarcopenia. However, our work is only based on the English language literature in the WoSCC database, and for future studies, we recommend that researchers explore the literature from multiple databases to enhance the scope of their research.

Research Progress on Epigenetic Mechanism of Sarcopenia

In recent years, sarcopenia, as a progressive muscular atrophy and weakness, has become one of the common diseases in the elderly. Although its cause is not fully understood, a growing body of research suggests that epigenetic mechanisms play an important role in the pathogenesis of sarcopenia. The purpose of this review is to summarize the current research progress in the epigenetics of sarcopenia, focusing on the role of DNA methylation, RNA methylation and non-coding RNA in the pathogenesis of sarcopenia. While exploring the epigenetic mechanism of sarcopenia, this study will also look into the application prospect of epigenetics in the treatment strategy of sarcopenia, which will provide new ideas and directions for the treatment of sarcopenia.

Heart Failure-Like Reaction Is Likely Involved in the Feeding Behaviour of Blood-Sucking Leeches

Medicinal leeches have been utilized in therapy for thousands of years. However, the adaptation physiology between leeches and hosts is not fully understand. To disclose the molecular mechanisms of adaptation between leech and host, the body transcriptomes of hunger and fed blood-sucking Poecilobdella javanica, Haemadipsa cavatuses, and Hirudo nipponia leeches were obtained by RNA sequencing, after comparison, a stratified unigenes group was obtained, which closely correlated to body distension. In the group, Rfamide receptor decreased significantly (P < 0.05) while serotonin receptor increased significantly (P < 0.05). Moreover, four KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways, including cardiac muscle contraction, complement and coagulation cascades, renin-angiotensin system, and hypertrophic cardiomyopathy were significantly enriched. The unigenes annotation, neuroregulators correlation analysis and induced function of the KEGG pathways, were consistently supported the same result as: vasoconstriction and systole reaction enhance in hunger leeches and vice versa vasodilation and diastole increase in fed leeches, meanwhile, Interspecific comparison and correlative analyses of physiological function showed that the strongest reaction of induced heart failure from four KEGG occur in strongest reaction of systole in hungry P. javanica and in strongest reaction of diastole in fed H. nipponia. Overall, heart failure is likely a physiological function involved in feeding behaviour.

Mammals of Gaoligong Mountain in China:Diversity,distribution,and conservation

Gaoligong Mountain(hereafter,GLGM)is located at the intersection of Myanmar and China’s Yunnan Province and Xizang Zizhiqu,and spans three globally significant biodiversity hotspots:the Himalayas,Indo-Burma,and the Mountains of Southwest China.Although surveys of mammals in this ecologically important region have a long history,there is no comprehensive systematic checklist and distribution account of the mammals of GLGM.Here,we compiled a mammal species checklist of GLGM based on thorough field investigations and literature reviews.We also examined specimen collections and applied camera trapping surveys to explore the region’s mammal diversity and distribution patterns.We recorded 212 mammal species in nine orders,33 families,and 119 genera,which accounts for 30.5%of China’s mammal species,and a high proportion of nationally protected(50)and globally threatened(29)species.Mammal species richness showed a symmetrical unimodal curve along the elevation gradient,peaking at intermediate elevations(2000 to 2500 m above sea level(asl)),and increasing generally from south to north,slightly higher in the east slope than in the west.Cluster analysis and non-metric multidimensional scaling revealed three distinct elevational assemblages(<900 m asl.,900-3500 m asl.,and>3500 m asl)and significant south-to-north variation,but no substantial differences between the east and west slopes.The GLGM present a unique conservation value due to the high proportions of rare and endangered mammal species,complex faunal composition,high endemism,and being the distribution boundary for many species.This study is an important phased account of mammal diversity in GLGM and makes a prospect for future research.

Achievements and challenges of primate conservation in China

The dual impact of climate change and human activities has precipitated a sharp decline in primate biodiversity globally.China is home to the most diverse primate species in the Northern hemisphere,which face severe ecological threats due to the expansion of modern agriculture,extensive exploitation and consumption of natural resources,and excessive land development during its transition from an agricultural to a modern society.In response,China has implemented various ecological conservation measures,including habitat restoration and protection.These efforts have made substantial strides in biodiversity conservation,with certain regions witnessing an increase in primate populations.In the current study,we conducted a systematic review of historical documents and field research data related to Chinese primates,evaluating the endangered status of primate species in China.Despite improvements in the habitats of most primate species and some population growth,many species still face severe threats,including declining and small populations.Species such as the Myanmar snub-nosed monkey(Rhinopithecus strykeri),eastern black crested gibbon(Nomascus nasutus),and Hainan gibbon(N.hainanus)remain particularly vulnerable due to their limited distribution ranges and extremely small populations.Insufficient scientific data,fragmented information,and not enough studies in conservation biology further compound the challenges.Moreover,there is a notable lack of detailed population monitoring data for species such as the Bengal slow loris(Nycticebus bengalensis),pygmy slow loris(N.pygmaeus),Indochinese gray langur(Trachypithecus crepusculus),Shortridge’s langur(T.shortridgei),and capped langur(T.pileatus),which hinders the development of practical and targeted conservation management strategies.Therefore,for national biodiversity conservation,there is an urgent need for specialized primate surveys,enhancing habitat protection and restoration,and increasing focus on cross-border conservation strategies and regional cooperation.There is also a need to establish a comprehensive and systematic research database platform,conduct continuous and in-depth research in primate biology,and actively engage in the scientific assessment of ecotourism.Additionally,strengthening public awareness and education on wildlife conservation remains essential.Such integrated and systematic efforts will provide scientific support for the current and future conservation and management of primate species in China.

Research on Hepatitis B virus Genotypes and Subgenotypes among Bai Nationality in Dali, Yunnan Province

To investigate the distribution of hepatitis B virus (HBV) genotypes and subgenotypes among the Bai nationality in Dali, a total of 100 serum samples from patients with chronic HBV-infection were collected for the detection of HBV genotypes and subgenotypes by genotype-specific primers and restriction fragment length polymorphism (RLFP), respectively. Among the 100 samples, the proportions of genotype B, C and mixed genotype (B+C) were 41%, 25% and 34%, respectively. All the genotype B strains belonged to subgenotype Ba. In genotype C, 84% were Subgenotype Cs and 12% were subgenotype Ce. The distribution of genotypes B, C and B+C showed no significant difference between male and female patients (P=0.182) and among the age groups of patients (P=0.812). The rates of HBeAg/HBeAg positivity were no significantly different among genotypes B, genotype C and mixed genotype (B+C) (P=0.077/P=0.663). In Dali, genotypes B, B+C and C existed among Bai nationality with chronic HBV-infection, and genotype B was the major genotype. Subgenotypes Ba and Cs were the predominant strains in patients with HBV genotype B/C infection. The most prominent characteristic was the higher prevalent rate of mixed genotype (B+C) in patients.

Conflict management and perceived team cohesion of nurses in university hospitals

Objective Team cohesion is an essential component in a multidisciplinary team and can inspire the team to perform creative and complex works.This descriptive correlational study aimed to determine the styles of conflict management,levels of team cohesion,and the relationship between each style of conflict management and perceived team cohesion among nurses at affiliated hospitals of Dali University.Methods The sample consisted of 336 nurses from two university hospitals in Yunnan province,selected using the proportionate sampling method.Research instruments included demographic data form,Dutch Test for Conflict Handling(DUTCH)and Group Cohesion Scale.The Cronbach’s alpha coefficient for the five subscales of DUTCH were the following:forcing(0.83),yielding(0.81),avoiding(0.88),problem-solving(0.85),and compromising(0.84).The Cronbach’s alpha coefficient of Group Cohesion Scale was 0.83.Data were analyzed using descriptive statistics and Spearman’s rank-order correlations.Results The results of this study revealed that nurses were most likely to use avoiding conflict management style to deal with conflict situations,followed in rank order by problem-solving,compromising,forcing and yielding conflict management style.Nurses perceived team cohesion at a moderate level(x=4.43,SD=2.01).Additionally,conflict management associated with team cohesion.Conclusion The study findings revealed that avoiding was the conflict management style most frequently utilized by nurses,and nurses perceived team cohesion was at a moderate level.It is required to identify various strategies to improve team cohesion in multidisciplinary teams and develop a support system for nurses.

Origins,Changes,and Integration:Cross-Cultural Art Between Dali and the Kingdom of Sukhothai

Since it was suggested at the end of the 19th century that Thai people originally came from Southern China,“Dali and Sukhothai”has become one of the most controversial topics of Southeast Asian studies.This paper aims at showing the existence of a transcultural phenomenon between the arts and cultures of Dali and Sukhothai.In order to exam in this,this paper confronts two propositions:early Tai people establishing the Nanzhao Kingdom in Dali,and the move to the South of the Tai people.The paper focuses on three causes of the transcultural art of Dali and Sukhothai:(1)South East Asia as a cultural entity,(2)the geo-civilisational influence,(3)the trans-border ethnic migrations.

A hyaluronic acid granular hydrogel nerve guidance conduit promotes regeneration and functional recovery of injured sciatic nerves in rats

A hyaluronic acid granular hydrogel can promote neuronal and astrocyte colony formation and axonal extension in vitro,suggesting that the hydrogel can simulate an extracellular matrix structure to promote neural regeneration.However,in vivo experiments have not been conducted.In this study,we transplanted a hyaluronic acid granular hydrogel nerve guidance conduit to repair a 10-mm long sciatic nerve gap.The Basso,Beattie,and Bresnahan locomotor rating scale,sciatic nerve compound muscle action potential recording,Fluoro-Gold retrograde tracing,growth related protein 43/S100 immunofluorescence staining,transmission electron microscopy,gastrocnemius muscle dry/wet weight ratio,and Masson’s trichrome staining results showed that the nerve guidance conduit exhibited similar regeneration of sciatic nerve axons and myelin sheath,and recovery of the electrophysiological function and motor function as autologous nerve transplantation.The conduit results were superior to those of a bulk hydrogel or silicone tube transplant.These findings suggest that tissue-engineered nerve conduits containing hyaluronic acid granular hydrogels effectively promote the morphological and functional recovery of the injured sciatic nerve.The nerve conduits have the potential as a material for repairing peripheral nerve defects.

Giant juvenile fibroadenoma in a 14-year old Chinese female:A case report

BACKGROUND A giant juvenile fibroadenoma(GJF)is a rare,benign breast tumor that affects females<18 years of age.GJFs are generally suspected based on a palpable mass.GJFs influence breast shape and mammary gland development via the pressure effect from their enormous size.CASE SUMMARY Herein we report a case involving a 14-year-old Chinese female with a GJF in the left breast.GJF is a rare,benign breast tumor that usually occurs between 9 and 18 years of age and accounts for 0.5%-4.0%of all fibroadenomas.In severe cases,breast deformation may occur.This disease is rarely reported in Chinese people and has a high clinical misdiagnosis rate due to the absence of specific imaging features.On July 25,2022,a patient with a GJF was admitted to the First Affiliated Hospital of Dali University.The preoperative clinical examination and conventional ultrasound diagnosis needed further clarification.The mass was shown to be an atypical lobulated mass during the operation and confirmed to be a GJF based on pathologic examination.CONCLUSION GJF is also a rare,benign breast tumor in Chinese women.Evaluation of such masses consists of a physical examination,radiography,ultrasonography,computer tomography,and magnetic resonance imaging.GJFs are confirmed by histopathologic examination.Mastectomy is not selected when the patient benefits from a complete resection of the mass with breast reconstruction and an uneventful recovery.

Plastid phylogenomics and species discrimination in the“Chinese”clade of Roscoea(Zingiberaceae)

Roscoea is an alpine or subalpine genus from the pan-tropical family Zingiberaceae,which consists of two disjunct groups in geography,namely the"Chinese"clade and the"Himalayan"clade.Despite extensive research on the genus,Roscoea species remain poorly defined and relationships between these species are not well resolved.In this study,we used plastid genomes of nine species and one variety to resolve phylogenetic relationships within the"Chinese"clade of Roscoea and as DNA super barcodes for species discrimination.We found that Roscoea plastid genomes ranged in length from 163,063 to 163,796 bp,and encoded 113 genes,including 79 protein-coding genes,30 tRNA genes,four rRNA genes.In addition,expansion and contraction of the IR regions showed obvious infraspecifc conservatism and interspecific differentiation.Plastid phylogenomics revealed that species belonging to the"Chinese"clade of Roscoea can be divided into four distinct subclades.Furthermore,our analysis supported the independence of R.cautleoides var.pubescens,the recovery of Roscoea pubescens Z.Y.Zhu,and a close relationship between R.humeana and R.cautloides.When we used the plastid genome as a super barcode,we found that it possessed strong discriminatory power(90%)with high support values.Intergenic regions provided similar resolution,which was much better than that of protein-coding regions,hypervariable regions,and DNA universal barcodes.However,plastid genomes could not completely resolve Roscoea phylogeny or definitively discriminate species.These limitations are likely related to the complex history of Roscoea speciation,poorly defined species within the genus,and the maternal inheritance of plastid genomes.

LISC Catalog of Open ClustersⅢ.83 Newly Found Galactic Disk Open Clusters Using Gaia EDR3

As groups of coeval stars born from the same molecular cloud,an open cluster(OC)is an ideal laboratory for studying the structure and dynamical evolution of the Milky Way.The release of high-precision Gaia Early Data Release 3(Gaia EDR3)and modern machine-learning methods offer unprecedented opportunities to identify OCs.In this study,we extended conventional HDBSCAN(e-HDBSCAN)for searching for new OCs in Gaia EDR3.A pipeline was developed based on the parallel computing technique to blindly search for OCs from Gaia EDR3within Galactic latitudes∣b∣<25°.As a result,we obtained 3787 star clusters,of which 83 new OCs were reported after cross-match and visual inspection.At the same time,the main star cluster parameters are estimated by color-magnitude diagram fitting.The study significantly increases the sample size and physical parameters of OCs in the catalog of OCs.It shows the incompleteness of the census of OCs across our Galaxy.

Anxiety, Depression and Quality of Life in Patients with Chronic Obstructive Pulmonary Disease

Background: Chronic Obstructive Pulmonary Disease (COPD) is a common and frequently occurring disease, which not only has a higher fatality rate, but also leads to loss of labor force and an obvious decrease in the quality of life in the course of long-term disease, patients with chronic obstructive pulmonary disease complicated with anxiety and depression are a major public health problem. Objective: To investigate the status of anxiety, depression and quality of life and related factors in patients with COPD. Methods: One hundred patients admitted to the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Dali University with chronic obstructive pulmonary disease evaluated by anxiety self-assessment scale, depression self-assessment scale and quality of life rating scale for patients with chronic obstructive pulmonary disease. Results: The incidence of anxiety in COPD patients was 82.5%, and the incidence of depression was 87.3%. The probability of both anxiety and depression was high, and the prevalence of women was significantly higher than that of men. Correlation analysis and logistic regression results showed that education level was negatively correlated with the occurrence of anxiety, and age was positively correlated with the occurrence of anxiety. Elderly patients were prone to anxiety and had lower quality of life. Conclusion: The older and less educated the COPD patients are, the higher the incidence of anxiety and depression, and the higher the incidence in female patients.
