With the completion of the "Human Genome Project" and the smooth progress of the "Herbal Genome Project", the research wave of RNAomics is gradually advancing, opening the research gateway for the modernization of traditional Chinese medicine (TCM) and initiating the post-genome era of medicinal plant RNA research. Therefore, this article proposes for the first time the concept of HerbRNomes, which involves constructing databases of medicinal plant, medicinal fungus, and medicinal animal RNA at different stages, from different origins, and in different organs. This research aims to explore the role of HerbRNA in self-genetic information transmission, functional regulation, as well as cross-species regulation functional mechanisms and key technologies. It also investigates application scenarios, providing a theoretical basis and research ideas for the resistance of TCM or medicinal plants to adversity and stress, molecular assistant breeding, and the development of small nucleic acid drugs. This article reviews recent research progress in elucidating the molecular mechanisms of the transmission and expression of genetic information, self-regulation and cross-species regulation of herbs at the RNA level, along with key technologies. It proposes a development strategy for small nucleic acid drugs based on HerbRNomes, providing theoretical support and guidance for the modernization of TCM based on HerbRNomes research.

This paper systematically summarizes the practical experience of the 2025 Dingri earthquake emergency medical rescue in Tibet. It analyzes the requirements for earthquake medical rescue under conditions of high-altitude hypoxia, low temperature, and low air pressure. The paper provides a detailed discussion on the strategic layout of earthquake medical rescue at the national level, local government level, and through social participation. It covers the construction of rescue organizational systems, technical systems, material support systems, and information systems. The importance of building rescue teams is emphasized. In high-altitude and cold conditions, rapid response, scientific decision-making, and multi-party collaboration are identified as key elements to enhance rescue efficiency. By optimizing rescue organizational structures, strengthening the development of new equipment, and promoting telemedicine technologies, the precision and effectiveness of medical rescue can be significantly improved, providing important references for future similar disaster rescues.

Phosphatidylinositol 4 kinases are the initial and key molecules of the phosphatidyl inositol signaling pathway.Among them,the phosphatidylinositol 4-kinaseⅢ β(PI4KⅢβ)is in-volved in the synthesis of the Golgi PI4P pool,playing a vital role in numerous physiological processes.Meanwhile,the en-zyme is an important host factor mediating the replication of some pathogenic RNA viruses,and participating in other patho-logical processes such as bacterial infection and malaria.In ad-dition,studies have shown that the function of PI4KⅢβ is regu-lated by numerous factors,including host and viral protein bind-ing partners.This review will discuss the structure and the phys-iopathology regulatory mechanism of PI4KⅢβ.

Vascular calcification is a highly regulated process of ectopic calcification in cardiovascular system while no effective intervention can be clinically performed up to date.As vascular calcification undergoes a common regulatory mechanism within bone formation,bone morphogenetic protein 7(BMP-7)main-tains contractile phenotype of vascular smooth muscle cells and further inhibits vascular calcification via promoting the process of osteoblast differentiation,reducing ectopic calcification pressure by increasing bone formation and reducing bone resorption.This work systematically reviews the role of BMP-7 in vascular calcifi-cation and the possible mechanism,and their current clinical application as well.The current proceedings may help develope early diagnostic strategy and therapeutic treatment with BMP-7 as a new molecular marker and potential drug target.The expec-tation could achieve early prevention and intervention of vascular calcification and improve poor prognosis on patients.

Objective To explore the effect of Kümmell's disease with kyphosis on the sagittal morphology of the spine-pelvis.Methods A retrospective analysis of 34 patients of Kümmell's disease with kyphosis(Kümmell group)admitted from August 2015 to September 2022,including 10 males and 24 females with an average age of(71.1±8.5)years old.A control group of 37 asymptomatic population aged(69.3±6.7)years old was matched.Spinal-pelvic sagittal parameters were measured on the anterior-posterior and lateral X-rays of the whole spine in the standing position,including segmental kyphosis(SK)or thoracolumbar kyphosis(TLK),thoracic kyphosis(TK),lumbar lordosis(LL),pelvic incidence(PI),pelvic tilt(PT),sacral slope(SS),sagittal vertical axis(SVA),T1 pelvic angle(TPA)and PI-LL.Vertebral wedge angle(WA)in Kümmell was mea-sured and differences in parameters among groups were analyzed and the relationship between spino-pelvic parameters and WA,SK were also investigated.Results TK,SK,PT,SVA,TPA and PI-LL in Kümmell group were significantly larger than those in control group(P＜0.05),LL and SS in Kümmell group were significantly decreased than those in control group(P＜0.05),and there was no significant difference in PI between two groups(P＞0.05).In Kümmell group,WA(30.8±5.9)° showed a positive correlation with SK and TK(r=0.366,0.597,P＜0.05),and SK was significantly correlated with LL and SS(r=0.539,-0.591,P＜0.05).Strong positive correlation between LL and PI,SS,SVA,TPA,PI-LL were also confirmed in patients with Kümmell with kyphosis(r=0.559,0.741,-0.273,-0.356,-0.882,P＜0.05).Conclusion Patients with Kümmell with kyphosis not only have segmental kyphosis,but also changes the overall spinal-pelvic sagittal parameters,including loss of lumbar lordosis,pelvic retrorotation,trunk forward tilt.The surgical treatment of Kümmell disease should not only pay attention to the recovery of the height of the collapsed vertebra,but also focus on the overall balance of the spine-pelvic sagittal plane for patients with kyphosis.

The feasibility of fecal-oral transmission of Trichinella spiralis larva and infectivity in feces were assessed.Six Wistar rats were infected with 4 000 T.spiralis larvae at one time.The feces of three rats(group A)were collected at 0,4,8,12,16,24,and 48 h,and then divided into four aliquots and stored at room temperature for 0,24,48,and 72 h,respectively.The number of larvae in the feces was counted under a microscope,and each aliquot containing T.spiralis larvae was fed to five Kunming mice.All mice were killed 42 days after infection.The number and reproductive capacity index(RCI)of T.spir-alis larva were calculated.The feces from another three Wistar rats(group B)were collected from 1 to 23 days after infection and DNA was extracted from each fecal sample for PCR detection of the mitochondrial atp6 gene of T.spiralis.The results showed that T.spiralis was discharged in feces at 4-16 h after infection,peaking at 8 h,with no detection after 24 h.The numbers of T.spiralis larva in fecal samples of three rats in group A were 350,400,145,and 40 at 4,8,12,and 16 h after infection,respectively.The RCI values of T.spiralis larva for samples collected at 4 h were 112.5,20.5,and 2 after storage at room temperature for 0,24,and 48 h,66.7 and 9 for samples collected at 8 h after 0 and 24 h,13.3 and 5 for samples collected at 12 after 0 and 24 h,and 10 for samples collected at 16 h after 0 h,respectively.Of the three rats in group B,two were posi-tive for the atp6 gene for 18 consecutive days,and the third was positive for 20 consecutive days.These results indicate that one-time ingestion of T.spiralis larva in quantity can discharge infectious T.spiralis larvae,which can be transmitted through the fecal-oral route.PCR analysis is appropriate for detection of the T.spiralis atp6 gene in feces,but not infectivity of T.spiralis.

This study was aimed at understanding the genomic characteristics of the Vibrio cholerae O1 group isolated from humans in Fujian Province,to provide essential data for the molecular epidemiological study of cholera.From 2008 to 2022,16 strains of the V.cholerae O1 group from patients and carriers were collected,and antibiotic sensitivity was determined accord-ing to the minimum inhibitory concentration(MIC).The whole genome sequences obtained through second generation sequen-cing were analyzed in open source software,including snippy,Roary,and Prokka,as well as online analysis websites,inclu-ding NCBI and BacWGSTdb,for core-genome multilocus sequence typing(cgMLST),core-genome single nucleotide polymor-phism analysis(cgSNP),virulence gene analysis,drug resistance gene prediction,and pan-genomic diversity analysis.The whole genome sequences of V.cholerae were divided into five sequence types(STs),among which the newly discovered ST182 and ST1480 were the evolutionary branches of the current dominant clonal group ST75 in China,and were highly related to two strains isolated from Taiwan in 2010 and 2013,respectively.Both toxigenic strains and non-toxigenic strains carried a variety of virulence factors and showed gene variation to varying degrees.Thirteen drug resistance genes in seven categories were predicted,among which the distribution of colistin and tetracycline resistance genes was consistent with the drug resistance phenotype.Pan-ge-nomic analysis indicated that V.cholerae had an open pan-genome,and Roary cluster analysis showed higher resolution than cgMLST.In summary,V.cholerae O1 group isolates from humans in Fujian Province have polymorphisms in genome structure and function,and the newly discovered ST1480 clone group has epidemic potential.Therefore,the monitoring of such strains must be strengthened.

This study was aimed at investigating the pathogenic and molecular characteristics of Klebsiella pneumoniae(KP)in fecal samples of diarrhea cases in a district of Beijing.Fecal samples from diarrhea cases in an outpatient department in a district of Beijing from 2018 to 2021 were collected,and used for isolation and culture of KP.The KP strains isolated strains were subjected to drug resistance phenotype testing and whole-genome sequencing.Multilocus sequence typing and whole-genome phyletic evolution analysis were performed on the sequencing results.The cases'epidemiological and clinical characteristics were analyzed.From 2018 to 2021,1 103 fecal samples were collected and detected.The total detection rate of KP was 10.43％(115/1 103),and the infection rate of KP mixed with other diarrhea-causing pathogens was 42.61％(49/115).The positivity rate was slightly high(12.47％,61/489)a-mong females and was highest in young adults 16-45 years of age.Small peaks were observed in January,April to May,and August to September.The gastrointestinal symptoms in cases were mainly nausea and watery stool,and the suspicious food was unknown.Ampicillin,tetracycline,and sulfafurazole were the top three antibiotics to which these 115 KP strains showed resistance,and 29 strains were resistant to multiple antibiotics.The strains were divided into 72 sequence types,among which ST23 was dominant.According to the phylogenetic tree,the strains were divided into four main branches,among which 14 ST23 strains had a very close genetic relationship with the highly virulent NTUH-K2044 reference strain.KP infection persisted in fecal samples from diarrhea cases in the district of Beijing.Women and young adults were particularly susceptible.The drug resistance of KP strains in this region was very serious,and the ST types were diverse.Moreover,the ST23 pathogenic strains were closely related to high virulence strains.
