Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

Endoscopic transforaminal lumbar interbody fusion (TLIF) offers substantial advantages in the management of degenerative spinal diseases, including accelerated postoperative recovery. However, its technical complexity and steep learning curve pose risks for nerve root injury. Optimizing nerve root protection in full-endoscopic facet-sparing TLIF (FE fs-TLIF) and full-endoscopic facet-resecting TLIF (FE fr-TLIF) is essential for enhancing surgical safety. This study aimed to improve the nerve root protection in FE fs-TLIF and FE fr-TLIF by optimizing cage glider selection and insertion techniques based on the specific cage shape—banana-shaped or bullet-shaped. The goal was to ensure safe cage positioning and mitigate nerve root injury during discectomy, endplate preparation, and cage insertion. These strategies were validated through cadaveric simulations and clinical implementation. In FE fr-TLIF utilizing bullet-shaped (straight) cages, one-tip and two-tip cage gliders effectively protected the traversing nerve root by facilitating medial cage entry, thereby minimizing irritation of the exiting nerve root. Conversely, in FE fr-TLIF with banana-shaped cages, the lateral tilt of the cage holder during implantation required the use of a two-tip cage glider to protect the traversing and exiting nerve roots, thereby mitigating the potential risk of nerve irritation. In FE fs-TLIF, a one-tip cage glider is preferred for safeguarding the exiting nerve root, while the traversing root is inherently protected by the medial wall of the facet joint. The use of a two-tip cage glider in FE fs-TLIF can cause injury to the nerve root during glider insertion. In addition to the selection of cage gliders, improper cage insertion steps can also contribute to postoperative neurapraxia. The appropriate selection of cage gliders with corresponding insertion techniques is critical for nerve root protection in endoscopic TLIF. Tailoring these choices to the specific approach (FE fs-TLIF or FE fr-TLIF) and cage type (banana or bullet) enhances surgical safety and clinical outcomes.

ObjectiveTo investigate the risk factors for postpancreatectomy acute pancreatitis (PPAP) after minimally invasive pancreaticoduodenectomy (MIPD) and their association with major complications, to improve the understanding of PPAP and postoperative pancreatic fistula (POPF), and to reduce the incidence rates of PPAP and POPF. MethodsA retrospective analysis was performed for the clinical data of 114 patients who underwent MIPD in Department of Hepatobiliary and Pancreatic Surgery, The First Affiliated Hospital of University of South China, from March 2015 to December 2023, and the definition of PPAP and its diagnostic criteria provided by the International Study Group of Pancreatic Surgery were used to determine the presence or absence of PPAP. The independent samples t-test or the Mann-Whitney U rank sum test was used for comparison of continuous data between groups, and the Kruskal-Wallis H test was used for comparison between multiple groups, and the Dunn-test was used for further comparison between two groups.; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups., and the Bonferroni-test was used for further comparison between two groups. The multivariate logistic regression analysis was used to identify the risk factors for PPAP after MIPD. ResultsOf all 114 patients undergoing MIPD, 27 (23.7%) experienced PPAP. The multivariate analysis showed that main pancreatic duct diameter ≤3 mm (odds ratio [OR]=5.083, 95% confidence interval [CI]: 1.703 — 15.172, P=0.004), soft pancreatic texture (OR=5.925, 95%CI: 1.986 — 17.677, P=0.001), and C-reactive protein ≥180 mg/L on day 1 after surgery (OR=5.419, 95%CI: 1.586 — 18.513, P=0.007) were independent risk factors for the onset of PPAP after MIPD. Clinical analyses showed that the patients with PPAP tended to have significantly higher incidence rates of POPF, peritoneal infection, Clavien-Dindo grade 3/4 complications, discharge with tube, and 90-day postoperative death (χ2=5.676, 5.460, 9.863, 5.439, and 4.207, all P<0.05). ConclusionMain pancreatic duct diameter, pancreatic texture, and C-reactive protein on day 1 after surgery are closely associated with the onset of PPAP after MIPD, and PPAP can lead to other postoperative complications and even death.

ObjectiveTo investigate the mechanism by which Luoshi Neiyi prescription treats endometriosis (EMs) through the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway. MethodsAnimal experiments were conducted with 50 female SD rats, which were randomized into a sham operation group (10 rats) and a modeling group (40 rats). An autologous endometrial transplantation method was used for the modeling of EMs. The 36 successfully modeled rats were randomly allocated into four groups (n=9 each): The model group, the low-dose (7.87 g·kg-1) Luoshi Neiyi prescription group, the high-dose (15.74 g·kg-1) Luoshi Neiyi prescription group, and the dienogest (0.20 mg·kg-1) group. The physiological status and ectopic lesion volumes of rats in each group were observed. Hematoxylin-eosin (HE) staining was used to observe the morphology of the eutopic endometrial tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of inflammatory factors including interleukin-1β (IL-1β) and prostaglandin E2 (PGE2) in the serum of EMs rats. Immunohistochemistry was used to detect the expression of matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor A (VEGFA) in the eutopic endometrial tissue. Western blot was adopted to determine the protein levels of TLR4, myeloid differentiation factor 88 (MyD88), phosphorylated nuclear factor-κB (p-NF-κB)/NF-κB, MMP-9, and VEGFA in the eutopic endometrial tissue. In the cell experiments, the cell-counting kit-8 (CCK-8) assay was employed to screen the optimal concentration of Luoshi Neiyi prescription-containing serum, and a scratch assay was performed to assess the migration ability of iheESCs cells. Interventions with Luoshi Neiyi prescription-containing serum, resatorvid (TAK-242, a TLR4 inhibitor), and lipopolysaccharides (LPS, a TLR4 agonist) were conducted, and Western blot was used to detect the expression of proteins related to the TLR4/NF-κB signaling pathway. ResultsThis experiment successfully replicated 36 EMs rat models. Compared with the sham operation group, the model group exhibited visible ectopic lesions on the abdominal wall and an increase in the writhing response score (P<0.01). Furthermore, HE staining revealed the model group exhibited a thickened eutopic epithelium, stromal cell disarrangement, and evident infiltration of inflammatory cells. In addition, the model group showed elevated serum levels of IL-1β and PGE2 (P<0.05, P<0.01), increased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue (P<0.01), and up-regulated protein levels of TLR4, MyD88, p-NF-κB/NF-κB, MMP-9, and VEGFA in the ectopic endometrial tissue (P<0.05, P<0.01). Compared with the model group, all treatment groups exhibited a reduction in the ectopic lesion volume (P<0.01). Furthermore, the writhing response scores were decreased in the high-dose Luoshi Neiyi prescription group and the dienogest group (P<0.05, P<0.01). The pathological state of the ectopic endometrial tissue was alleviated to varying degrees in the treatment groups. Low-dose Luoshi Neiyi prescription reduced serum PGE2 levels, and high-dose Luoshi Neiyi prescription and dienogest decreased serum IL-1β and PGE2 levels in EMs rats (P<0.05, P<0.01). The treatment groups showed decreased positive expression of MMP-9 and VEGFA in the ectopic endometrial tissue (P<0.05, P<0.01) and down-regulated protein levels of TLR4, MyD88, p-NF-κB/NF-κB, MMP-9, and VEGFA in the ectopic endometrial tissue (P<0.05, P<0.01). The cell experiments showed that 5%, 10%, and 20% Luoshi Neiyi prescription-containing sera significantly reduced the viability and inhibited the migration of iheESCs. Compared with the control group, 5%, 10%, and 20% Luoshi Neiyi prescription-containing serum groups and the TAK-242 group showed reduced protein levels of TLR4, MyD88, p-NF-κB/NF-κB, MMP-9, and VEGFA (P<0.01). Compared with the control group, the LPS group showed increased expression of the above proteins (P<0.01). Compared with the LPS group, the LPS+5%, 10%, and 20% Luoshi Neiyi prescription-containing serum groups showed reduced expression of the above proteins (P<0.05, P<0.01). ConclusionLuoshi Neiyi prescription may modulate the TLR4/NF-κB signaling pathway to reduce the inflammatory response and histopathological damage in the eutopic endometrium and suppress the adhesive, invasive, and angiogenic biological processes in the ectopic endometrial tissue, thereby exerting its therapeutic effect on EMs.

Prostate cancer(PCa) is a common malignant tumor among elderly men, with high incidence and mortality rates worldwide, posing a serious threat to human health. Traditional treatments face limitations, highlighting the urgent need for novel therapeutic strategies. Recent studies on the regulatory mechanisms of micro ribonucleic acid(microRNA, miRNA) in tumor development has identified miRNA as new targets for PCa diagnosis and treatment. Traditional Chinese medicine(TCM), with its multi-mechanism, multi-target, and multi-pathway regulatory properties, shows promising potential in miRNA-based PCa therapy. This review summarized recent findings on miRNA' roles in PCa and research progress of TCM intervention and found that a variety of miRNA played important regulatory roles in cell differentiation, proliferation, apoptosis, invasion, metastasis, immune microenvironment, and drug resistance, and their potential as biomarkers for PCa diagnosis, prognosis, and therapy, indicating the potential to be a biomarker for the diagnosis, prognosis evaluation, and treatment of PCa. The review concluded that the active components of TCM(terpenoids, flavonoids, alkaloids, and others) and compounds(Yishen Tonglong Decoction, Shenhu Decoction, Zhoushi Qiling Decoction, Fuzheng Yiliu Decoction, and Qilan Formula) could regulate the expression of their downstream target genes by acting on specific miRNA and affect the above biological behaviors of PCa cells, thus playing a role in the treatment of PCa. This review aims to provide a theoretical basis for miRNA as potential biomarkers and therapeutic targets for PCa and suggest new avenues for further development of targeted therapy strategies against miRNA.

This study aims to explore the pharmacodynamic material basis of Jinbei Oral Liquid(JBOL) against idiopathic pulmonary fibrosis(IPF) based on serum pharmacochemistry and network pharmacology. The ultra-high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UHPLC-Q-TOF-MS/MS) technology was employed to analyze and identify the components absorbed into rat blood after oral administration of JBOL. Combined with network pharmacology, the study explored the pharmacodynamic material basis and potential mechanism of JBOL against IPF through protein-protein interaction(PPI) network construction, "component-target-pathway" analysis, Gene Ontology(GO) functional enrichment, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis. First, a total of 114 compounds were rapidly identified in JBOL extract according to the exact relative molecular mass, fragment ions, and other information of the compounds with the use of reference substances and a self-built compound database. Second, on this basis, 70 prototype components in blood were recognized by comparing blank serum with drug-containing serum samples, including 28 flavonoids, 25 organic acids, 4 saponins, 4 alkaloids, and 9 others. Finally, using these components absorbed into blood as candidates, the study obtained 212 potential targets of JBOL against IPF. The anti-IPF mechanism might involve the action of active ingredients such as glycyrrhetinic acid, cryptotanshinone, salvianolic acid B, and forsythoside A on core targets like AKT1, TNF, and ALB and thereby the regulation of multiple signaling pathways including PI3K/AKT, HIF-1, and TNF. In conclusion, JBOL exerts the anti-IPF effect through multiple components, targets, and pathways. The results would provide a reference for further study on pharmacodynamic material basis and pharmacological mechanism of JBOL.

This study selected 6 529 plant-based Chinese materia medica(PCMM) from Chinese Materia Medica as research subjects and applied a random permutation test to explore the overall correlation characteristics between nature and flavor, as well as the correlation characteristics after distinguishing different medicinal parts and harvest seasons. The results showed that the overall correlation characteristics between nature and flavor in PCMM were significantly associated in the following pairs: cold and bitter, cool and bitter, cool and astringent, cool and light, neutral and sweet, neutral and astringent, neutral and light, neutral and sour, hot and pungent, and warm and pungent. When analyzing the data by distinguishing medicinal parts and/or harvest seasons, new correlation patterns emerged, characterized by the disappearance of some significant correlations and the emergence of new ones. When analyzing by medicinal parts alone, significant correlations were found in the following cases: cold and light in leaves, cold and salty in barks, cool and sweet in fruits and seeds, neutral and pungent in whole herbs, neutral and salty in stems, and warm and salty in flowers. However, no significant correlations were found between cool and bitter in stems and other types of herbs, cool and astringent in fruits, seeds, flowers, and other types of herbs, cool and light in leaves, fruits, seeds, barks, flowers and other types of herbs, neutral and sweet in barks, neutral and astringent in whole herbs and stems, neutral and light in leaves, fruits, seeds, and flowers, neutral and sour in whole herbs, stems, barks, flowers, and other types of herbs, and hot and pungent in whole herbs, stems, flowers, and other types of herbs. When analyzing by harvest season alone, significant correlations were found in the following cases: cold and salty, and cool and sour in herbs harvested in winter, and neutral and salty in herbs harvested year-round. However, no significant correlation was found between cool and light in herbs harvested in winter. When considering both medicinal parts and harvest seasons, compared to the independent influence of medicinal parts, 14 new significant correlations emerged(e.g., the correlation between cool and bitter in stems harvested in spring), while 53 previously significant correlations disappeared(e.g., the correlation between cool and bitter in barks harvested in summer). Compared to the independent influence of harvest seasons, 11 new significant correlations appeared(e.g., the correlation between cold and light in barks harvested in autumn), while 50 previously significant correlations disappeared(e.g., the correlation between hot and pungent in leaves harvested in winter). This study is the first to reveal the influence of medicinal parts and harvest seasons on the correlation between nature and flavor in PCMM, which highlights that these two factors can interact and jointly affect nature-flavor correlations. Further research is needed to explore the underlying mechanisms. This study provides a deeper understanding of the inherent scientific connotations of herbal properties and offers a theoretical foundation for the cultivation and harvesting of PCMM.

Poor water solubility is the primary obstacle preventing the development of many pharmacologically active compounds into oral preparations. Self-nanoemulsifying drug delivery systems(SNEDDS) have become a widely used strategy to enhance the oral bioavailability of poorly soluble drugs by inducing a supersaturated state, thereby improving their apparent solubility and dissolution rate. However, the supersaturated solutions formed in SNEDDS are thermodynamically unstable systems with solubility levels exceeding the crystalline equilibrium solubility, making them prone to drug precipitation in the gastrointestinal tract and ultimately hindering drug absorption. Therefore, maintaining a stable supersaturated state is crucial for the effective delivery of poorly soluble drugs. Incorporating polymers as precipitation inhibitors(PPIs) into the formulation of supersaturated self-nanoemulsifying drug delivery systems(S-SNEDDS) can inhibit drug aggregation and crystallization, thus maintaining a stable supersaturated state. This has emerged as a novel preparation strategy and a key focus in SNEDDS research. This review explores the preparation design of SNEDDS and the technical challenges involved, with a particular focus on polymer-based S-SNEDDS for enhancing the solubility and oral bioavailability of poorly soluble drugs. It further elucidates the mechanisms by which polymers participate in transmembrane transport, summarizes the principles by which polymers sustain a supersaturated state, and discusses strategies for enhancing drug absorption. Altogether, this review provides a structured framework for the development of S-SNEDDS preparations with stable quality and reduced development risk, and offers a theoretical reference for the application of S-SNEDDS technology in improving the oral bioavailability of poorly soluble drugs.
