With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

OBJECTIVE To investigate the effects of the split formulas of Biyuan Heji(BYHJ)on paranasal sinus mucosal in-flammation in rats with acute rhinosinusitis(ARS)based on the pathogenesis of"wind-cold transforming into lung-heat".METHODS Unilateral nasal cavity occlusion combined with nasal dripping of Staphylococcus aureus were performed to establish a rat model of ARS.SD rats were randomly divided into blank,model,BYHJ(wind-cold removal+lung-heat removal),lung-heat removal,wind-cold removal,and positive drug groups,with 6 rats in each group.The rats were treated with the corresponding drugs for 7 d and then the samples were collected.HE staining was used to observe the pathological changes of rat paranasal sinus mucosa tissues,ELISA was employed to determine the levels of interleukin-1β(IL-1β),IL-6,IL-8,IL-9,IL-10,and IL-12 in serum,immunohistochemis-try(IHC)was adopted to measure the protein expression of tumor necrosis factor-α(TNF-α)and intercellular adhesion molecule(ICAM-1)in paranasal sinus mucosa tissues,and Western blot was used to detect the protein expression of phosphorylated p38 mito-gen-activated protein kinase(p38 MAPK),nuclear transcription factor-κB p50(NF-κB p50),and NF-κB p65 in paranasal sinus mucosa tissues.RESULTS The acute sinusitis rat inflammation model was successfully established.Compared with the model group,the water drinking,diet eating,and body weight of rats in the BYHJ group,wind-cold removal,lung-heat removal,and positive drug groups were significantly improved,the aggregation of inflammatory cells in the paranasal sinus mucosal tissue was reduced,and the levels of IL-1β,IL-6,IL-8,IL-9,and IL-12 in the serum were significantly reduced(P<0.01),IL-10 content significantly in-creased(P<0.01),the protein expression of TNF-α,ICAM-1,p38 MAPK,NF-κB p50,and NF-κB p65 in the paranasal sinus mucosa was significantly decreased(P<0.01).The comparison between various traditional Chinese medicine groups showed that the decrease of IL-1β,IL-6,IL-8,IL-9,IL-12,TNF-α,ICAM-1,p38 MAPK,NF-κB p50,and NF-κB p65 and the increase of IL-10 in the BYHJ group were better than those in the split formula groups(P<0.01),and the lung-heat removal group was better than the wind-cold removal group(P<0.01).CONCLUSION BYHJ and its split formulas can effectively inhibit the inflammatory response in rats with ARS.

Dry eye disease (DED) is a prevalent and intractable ocular disease induced by a variety of causes. Elevated sphingomyelin (SM) levels and pro-inflammatory cytokines were detected on the ocular surface of DED patients, particularly in the meibomian glands. Sphingomyelin synthase 2 (SMS2), one of the proteins involved in SM synthesis, would light a novel way of developing a DED therapy strategy. Herein, we report the design and optimization of a series of novel thiophene carboxamide derivatives to afford 14l with an improved highly potent inhibitory activity on SM synthesis (IC_{50, SMS2} = 28 nmol/L). Moreover, 14l exhibited a notable protective effect of anti-inflammation and anti-apoptosis on human corneal epithelial cells (HCEC) under TNF-α-hyperosmotic stress conditions in vitro, with an acceptable ocular specific distribution (corneas and meibomian glands) and pharmacokinetics (PK) profiles (t _{1/2, cornea} = 1.11 h; t _{1/2, meibomian glands} = 4.32 h) in rats. Furthermore, 14l alleviated the dry eye symptoms including corneal fluorescein staining scores and tear secretion in a dose-dependent manner in mice. Mechanically, 14l reduced the mRNA expression of Tnf-α, Il-1β and Mmp-9 in corneas, as well as the proportion of very long chain SM in meibomian glands. Our findings provide a new strategy for DED therapy based on selective SMS2 inhibitors.

Objective:To investigate the effects of Houttuynize Herba decoction on aspirin-induced gastric ulcer (GU) in mice; To discuss its mechanism.Methods:A total of 64 SPF male mice were selected, and 48 mice were randomly selected to establish the model by gavage of 20 mg/ml aspirin solution. The remaining 16 rats were treated as normal group by gavage with the same amount of normalsaline once a day for 7 consecutive days. After successful modeling, the remaining mice in the model group were randomly divided into 5 groups, with 8 mice in each group, namely normal saline group (given normal saline), omeprazole group (given omeprazole 0.5 mg/ml), Houttuynize Herba high-, medium- and low-dosage groups (given 1.08 g/ml, 0.54 g/ml, 0.27 g/ml), and the remaining 8 mice in the normal group were given the same amount of normal saline by gavage. The mice were treated by gavage once a day for 7 days. The number of Escherichia coli and Bifidobacterium in mouse feces was counted by bacterial culture method, and the ratio of Bifidobacterium to Escherichia coli (B/E value) was used to judge the imbalance of bacterial flora. The expression of interleukin-6 (IL-6) in serum was detected by magnetic particle chemiluminescence. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of prostaglandin E 2 (PGE 2) in the serum of mice to determine the level of inflammation. Hematoxylin-eosin staining was used to determine the ulcer and healing. ImageJ 1.8.0 was used to calculate the ulcer inhibition rate. The protein expression levels of IκBα, NF-κB-p65 subunit and phosphorylated IκBα (p-IκBα) and p65 (p-NF-κB-p65) subunits in gastric tissue of mice were evaluated by Western blot. Results:Compared with the normal group, the epithelial cells of the gastric mucosa were missing, the glands were irregularly arranged, and the tissue structure was severely damaged in the modeling group; the number of Escherichia coli in the intestine increased ( P<0.01), the number of Bifidobacterium decreased ( P<0.01), and the B/E value was less than 1 ( P<0.01); Serum PGE2 levels were decreased ( P<0.01), IL-6 levels were increased ( P<0.01); The expression of p-IκBα and p-NF-κB-p65 proteins in gastric tissues was elevated ( P<0.05). After 7 days of drug treatment, compared with the saline group, gastric mucosal cells and structures were improved, and weight gained in the Houttuynize Herba groups ( P<0.05); the rate of inhibition of ulcers in mice in the Houttuynize Herba high-dosage group was significantly improved ( P<0.01); the number of Bifidobacteria in the intestinal tract significantly increased ( P<0.01), that of Escherichia coli was diminished ( P<0.05), B/E value was greater than 1 ( P<0.05), IL-6 content in peripheral blood was reduced ( P<0.05), PGE 2 levels significantly increased ( P<0.01); the level of p-IκBα/IκBα and p-NF-κB-p65/NF-κB-p65 in the gastric tissues of mice decreased ( P<0.01). Conclusion:Houttuynize Herba decoction can effectively improve gastric mucosal injury in mice, and its mechanism may be related to regulating intestinal microorganisms, inhibiting the opening of IκBα/NF-κB pathway, and reducing inflammatory response.

Objective:To analyze the role of dandelion and mulberry leaf in the progression of acute myeloid leukemia(AML)by network pharmacology,and to clarify the active components and their mechanisms in treating AML.Methods:The active components of dandelion and mulberry leaf were screened by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP).The targets were predicted by SwissTargetPrediction Database.The AML-related genes and protein targets were retrieved from the SymMap Database,the GeneCards Human Gene Database,the DisGeNET Database,and the Online Mendelian Inheritance in Man(OMIM)Database.The AML-related genes and target genes of dandelion and mulberry leaf were compared by comparative analysis and were identify by the enrichment genes,followed by Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis.The drug-active component-target network and protein-protein interaction(PPI)network were constructed by Cytoscape 3.8.0 software,and the core genes were selected by CytoNCA plugin;the molecular docking was conducted by AutoDock software.Results:After filtering by databases,39 active components were identified,and 148 common targets between dandelion-mulberry leaf and AML were collected.The GO functional enrichment analysis mainly involved cytokine-mediated signaling pathways,positive regulation of kinase activity,and oxidative stress responses.The KEGG signaling pathway enrichment analysis focused on the phosphatidylinositol 3 kinase/protein kinase B(PI3K-AKT)signaling pathway,the tumor necrosis factor(TNF)signaling pathway,and the Janus kinase/signal transducer and activator of transcription(JAK-STAT)signaling pathway.The key targets were identified by topological analysis including signal transducer and activator of transcription 3(STAT3),epidermal growth factor receptor(EGFR),protein kinase B1(AKT1),recombinant human epidermal growth factor(EGF),vascular endothelial growth factor A(VEGFA),oncogene MYC,tumor protein P53(TP53),mitogen-activated protein kinase 3(MAPK3),cysteiny asparate specific protease-3(CASP3),oncogene SRC,heat shock protein 90 alpha family class A member 1(HSP90AA1),tenascin XB1(CTNNB1),phosphoinositide kinase-3 catalytic subunit alpha(PIK3CA),interleukin 6(IL-6),TNF,mitogen-activated protein kinase 1(MAPK1),and phosphatidylinositide kinase-3 regulatory subunit 1(PIK3R1).The molecular docking results showed the highest affinity pairing to be taraxerol with MYC(-8.74 kcal·mol-1),and quercetin,kaempferol,luteolin,and artemetin demonstrated good binding affinities with various targets.Conclusion:The main active components of dandelion-mulberry leaf,such as quercetin,taraxerol,kaempferol,luteolin,and artemetin,may exert the anti-AML effect by regulating AKT1,STAT3,HSP90AA1,IL-6,and MAPK1;regulation the PI3K-AKT signaling pathway may be the critical mechanism of anti-AML effect by dandelion-mulberry leaf.

Objective:To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients.Methods:The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed.Results:The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively ( P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively ( P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm 3, the median survival time of SIB and No-SIB group was 34.7 and 30.3 months ( P=0.155), respectively. In the patients whose GTV volume>50 cm 3, the median survival time of SIB and No-SIB group was 16.1 and 20.1 months ( P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group ( P<0.001). Conclusions:The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.

Objective:To evaluate the effect of definitive radiotherapy with different doses on overall survival (OS) and identify the prognostic factors of patients with non-metastatic esophageal squamous cell carcinoma (ESCC).Methods:Clinical data of 2 344 ESCC patients treated with definitive radiotherapy (RT) alone or chemoradiotherapy from 2002 to 2016 in 10 hospitals were collected and analyzed retrospectively. After the propensity score matching (PSM)(1 to 2 ratio), all patients were divided into the low-dose group (equivalent dose in 2 Gy fractions, EQD 2Gy<60 Gy; n=303) and high-dose group (EQD 2Gy≥60 Gy; n=606) based on the dose of radiation. Survival analysis was conducted by Kaplan- Meier method. Multivariate prognostic analysis was performed by Cox′s regression model. Results:The median follow-up time was 59.6 months. After the PSM, the 1-, 3- and 5-year overall survival (OS) rate was 66.5%, 34.7%, 27.2% in the low-dose group, 72.9%, 41.7% and 34.7% in the high-dose group, respectively ( P=0.018). The 1-, 3-and 5-year progression-free survival rate was 52.2%, 27.2%, 23.1% in the low-dose group, 58.3%, 38.1% and 33.9% in the high-dose group, respectively ( P=0.001). The outcomes of univariate analysis indicated that cervical/upper esophagus location, early (stage Ⅱ) AJCC clinical stage, node negative status, tumor length ≤5 cm, receiving intensity-modulated radiation therapy (IMRT), receiving concurrent chemotherapy and EQD 2Gy≥60 Gy were closely associated with better OS (all P<0.05). Multivariable analysis demonstrated that tumor location, regional lymph node metastasis, concurrent chemotherapy and EQD 2Gy were the independent prognostic factors for OS (all P<0.05). Conclusion:Three-dimensional conformal or IMRT with EQD 2Gy≥60 Gy yields favorable survival outcomes for patients with locally advanced ESCC.

Objective: To evaluate the prognostic factors of T1-2N0M0 esophageal squamous cell carcinoma (ESCC) treated with definitive radiotherapy. Methods: The clinical data of 196 patients with T1-2N0M0 ESCC who were treated with definitive radiotherapy in 10 hospitals were retrospectively analyzed. All sites were members of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG). Radiochemotherapy were applied to 78 patients, while the other 118 patients received radiotherapy only. 96 patients were treated with three-dimensional conformal radiotherapy (3DCRT) and 100 treated with intensity-modulated radiotherapy (IMRT). The median dose of plan target volume(PTV) and gross target volume(GTV) were both 60 Gy. The median follow-up time was 59.2 months. Log rank test and Cox regression analysis were used for univariat and multivariate analysis, respectively. Results: The percentage of normal lung receiving at least 20 Gy (V₂₀) was (18.65±7.20)%, with average dose of (10.81±42.05) Gy. The percentage of normal heart receiving at least 30 Gy (V₃₀) was (14.21±12.28)%. The maximum dose of exposure in spinal cord was (39.65±8.13) Gy. The incidence of radiation pneumonia and radiation esophagitis were 14.80%(29/196) and 65.82%(129/196), respectively. The adverse events were mostly grade 1-2, without grade 4 toxicity. Median overall survival (OS) and progression-free survival (PFS) were 70.1 months and 62.3 months, respectively. The 1-, 3- and 5-year OS rates of all patients were 75.1%、57.4% and 53.2%, respectively. The 1-, 3- and 5-year PFS rates were 75.1%、57.4% and 53.2%, respectively. Multivariate analysis demonstrated that patients′age (HR=1.023, P=0.038) and tumor diameter (HR=1.243, P=0.028)were the independent prognostic factors for OS, while tumor volume were the independent prognostic factor for PFS. Conclusions Definitive radiotherapy is a promising therapeutic method in patients with T1-2N0M0 ESCC. Patients′ age, tumor diameter and tumor volume may impact patients′ prognosis.
