Sepsis-induced coagulopathy(SIC),a critical and potentially lethal condition arising from sepsis,results in endothelial damage and significant coagulation dysregulation,making it a major factor contributing to mortality among sepsis patients.Early diagnosis and treatment of SIC are expected to improve the prognosis of sepsis patients.In 2019,the International Society on Thrombosis and Hemostasis(ISTH)issued the first guidelines for the diagnosis and treatment of SIC,but there are no corresponding protocols in China.Therefore,Chinese Society of Thrombosis,Hemostasis and Critical Care,Chinese Medicine Education Association,and Chinese People's Liberation Army Professional Committee of Critical Care Medicine jointly formulated the"Chinese Expert Consensus on the Diagnosis and Treatment of Sepsis-induced Coagulopathy(2024 edition)."This consensus includes 5 parts:pathogenesis,classification,laboratory approaches,diagnosis and treatment,with a total of 14 evidence-based recommendations to guide clinical practice.

Schisandra chinensis, a traditional Chinese medicinal herb, is rich in chemical constituents, including lignans, triterpenes, polysaccharides, and volatile oils. Clinically, it is commonly used to treat cardiovascular, cerebrovascular, liver, gastrointestinal, and respiratory diseases. Modern pharmacological studies have shown that S. chinensis extract and monomers have multiple pharmacological activities in lowering liver fat, alleviating insulin resistance, and resisting oxidative stress, and have good application prospects in alleviating nonalcoholic fatty liver disease(NAFLD). Therefore, this study reviewed the research progress on chemical constituents of S. chinensis and its effect on NAFLD in recent years to provide references for the research on S. chinensis in the treatment of NAFLD.

【Objective】 To investigate the expressions of P53 and Ki-67 in prostate cancer (PCa)and to explore their correlation with the clinicopathological characteristics. 【Methods】 The expressions of P53 and Ki-67 in 90 PCa patients were detected with immunohistochemistry. Patients’ age, preoperative prostate-specific antigen (PSA) level, postoperative Gleason score, pathological stage, and invasion of neurovascular cancer embolus of all patients were recorded. The relationship of P53 expression with the above indexes was evaluated. 【Results】 The positive rates of P53 and Ki-67 were 27.8% (25/90) and 46.7% (42/90), respectively. The positive rate of P53 in pT2 and pT3-T4 stage groups were 19.7% (13/66) and 50.0% (12/24) (P=0.005), and the positive rate of Ki-67 were 36.4% (24/66) and 75.0% (18/24) (P=0.001), respectively. The positive rate of Ki-67 in Gleason score ≤6, ≤7 and ≥8 groups were 30.4%, 53.8% and 66.7%, respectively, with statistical difference. Positive expression of P53 was related to Ki-67 expression, but not to patients’ age, preoperative PSA level, postoperative Gleason score and nerve and invasion of neurovascular cancer embolus. 【Conclusion】 P53 expression is related to tumor stage and Ki-67, while Ki-67 expression is associated with tumor stage ang grade.

italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.

Objective: Dianjixueteng is a geoherb in Yunnan Province, the source plant of which is Kadsura interior. However, the formation of this geoherb is not clear in genetic mechanism, in which genome size is the first step that should be known on the genomic level. In this study we aimed to estimate the genome sizes of source plants of K. interior and three related herbs K. heteroclita, K. longipedunculata, and K. coccinea by flow cytometry (FCM) and make a comparison. Methods: The genome sizes of K. interior, K. heteroclita, K. longipedunculata and K. coccinea, i.e., the source plants of Dianjixueteng and its relative medicinal materials, were estimated by FCM. The nuclei of K. interior were isolated using modified LB01 buffer, for the rest species, by the Galbraith's buffer. Results: The genome sizes of K. interior, K. heteroclita, K. longipedunculata, and K. coccinea were 7.36, 7.12, 7.01, and 5.15 pg/1C, respectively. Genome size of K. interior had no significant variation with those of K. heteroclita and K. longipedunculata (P = 0.296), which was significantly larger than that of K. coccinea. Conclusion: Genome size can not distinguish K. interior from K. heteroclita and K. longipedunculata, but could distinguish them from K. coccinea, which lays the foundation for future studies on genetic mechanism of the geoherb formation.

Dirigent(DIR) proteins are involved in the biosynthesis of lignin, lignans, and gossypol in plants and respond to biotic and abiotic stresses. Based on the full-length transcriptome of Schisandra chinensis, bioinformatics methods were used to preliminarily identify the DIR gene family and analyze the physico-chemical properties, subcellular localization, conserved motifs, phylogeny, and expression patterns of the proteins. The results showed that a total of 34 DIR genes were screened and the encoded proteins were 156-387 aa. The physico-chemical properties of the proteins were different and the secondary structure was mainly random coil. Half of the DIR proteins were located in chloroplast, while the others in extracellular region, endoplasmic reticulum, cytoplasm, etc. Phylogenetic analysis of DIR proteins from S. chinensis and the other 8 species such as Arabidopsis thaliana, Oryza sativa, and Glycine max demonstrated that all DIR proteins were clustered into 5 subfamilies and that DIR proteins from S. chinensis were in 4 subfamilies. DIR-a subfamily has the unique structure of 8 β-sheets, as verified by multiple sequence alignment. Finally, through the analysis of the transcriptome of S. chinensis fruit at different development stages, the expression pattern of DIR was clarified. Combined with the accumulation of lignans in fruits at different stages, DIR might be related to the synthesis of lignans in S. chinensis. This study lays a theoretical basis for exploring the biological functions of DIR genes and elucidating the biosynthesis pathway of lignans in S. chinensis.

Cambodia is rich in medicinal plant resources. One hundred and thirty-three medicinal material samples, including the hole herb, root, stem/branch, leaf, flower, fruit, seed, and resin, were collected from the Orussey Herbal Market in Phnom Penh, Cambodia, and then authenticated by ITS and psbA-trnH. A total of 46 samples were identified based on ITS sequences, belonging to 24 families, 40 genera, and 42 species. A total of 100 samples were identified by psbA-trnH sequences to belong to 42 families, 77 genera, and 84 species. A total of 103 samples were identified by two DNA barcodes. According to the morphological characteristics of the medicinal materials, 120 samples classified into 50 species, 86 genera, and 86 families were identified, and the majority of them were from Zingiberaceae, Fabaceae, and Acanthaceae. Such samples have been commonly used in traditional Cambodian medicine, Ayurvedic medicine, Unani medicine, traditional Chinese medicine, and ethnomedicine, but different medical systems focus on different functional aspects of the same medicinal material. The results of this study have demonstrated that DNA barcoding has a significant advantage in identifying herbal products, and this study has provided basic data for understanding the traditional medicinal materials used in Cambodia.

Objective:To investigate the allelopathic effects of water extracts from rhizosphere soil of three medicinal plants Rehmannia glutinosa，Pinellia ternata and Isatis indigotica on seed germination and seedling growth of Polygala tenuifolia， screen the stubble varieties suitable for crop rotation with P. tenuifolia， and provide some scientific basis for continuous cropping obstacles of P. tenuifolia. Method:The bioassay method was used to study the effects of rhizosphere soil water extracts from three medicinal plants Rehmannia glutinosa，Pinellia ternata and Isatis indigotica at concentrations of 0.3，0.6，0.9 g·mL^-1 on the germination of P. tenuifolia seed and seedling growth. Result:The rhizosphere soil water extracts of Rehmannia glutinosa and Pinellia ternata showed basically low-promotion and high-inhibition concentration effects on the final germination rate，germination potential，and germination index of P. tenuifolia seeds，while the water extract of Isatis indigotica showed significant allelopathic inhibition effect. All three rhizosphere soil water extracts showed significant allelopathic inhibition effects on the growth index of P. tenuifolia seedlings. Among them，the rhizosphere soil water extract of Rehmannia glutinosa showed lower inhibitory effect on the plant height and root length of P. tenuifolia seedlings than the other two water extracts. The photosynthetic pigment content，proline（Pro） content，and soluble sugar content of P. tenuifolia chinensis seedlings were the highest under 0.3 g·mL^-1 soil water extract of Rehmannia glutinosa， with relatively higher content of soluble protein， and relatively lower content of hydrogen oxide（H₂O₂）. Under the treatment of 0.9 g·mL^-1 soil water extract of Rehmannia glutinosa，P. tenuifolia seedlings had the highest peroxidase（POD） and superoxide dismutase（SOD） activities，low catalase（CAT） activity，and lowest content of malondialdehyde（MDA）. Conclusion:Based on the comprehensive analysis of the above experimental data and allelopathic effects，the water extract of rhizosphere of Rehmannia glutinosa can promote the germination of P. tenuifolia seeds to a certain extent，and lay the foundation for seedling resistance to biochemical stress. Therefore， Rehmannia glutinosa is more suitable for crop rotation with P. tenuifolia.
