Gouty arthritis （GA） is caused by monosodium urate（MSU） deposition due to purine metabolism disorders. In traditional Chinese medicine （TCM）， it falls under the category of "dampness-heat Bi syndrome"， with core pathogenesis involving dampness-heat accumulation and dysfunction of the spleen and kidney. The dampness-heat syndrome is the most common and the primary syndrome type during acute attacks. In Western medicine， GA is associated with purine metabolism imbalance and inflammation triggered by MSU crystals， involving pathways such as NOD-like receptor protein 3 （NLRP3） inflammasome activation and Toll-like receptor 2/4 （TLR2/4） signaling. Clinically， colchicine and similar drugs are commonly used to treat GA， although long-term use carries potential side effects. Ermiao Formula analogs originate from ancient prescriptions， including Ermiao， Sanmiao， and Simiao compound formulas. All contain Atractylodis Rhizoma and Phellodendri Chinensis Cortex. Ermiaowan follow a 1∶1 formulation ratio. Sanmiaowan add Cyathulae Radix. Simiaowan further incorporate Coicis Semen. These formulas are rich in active ingredients， including alkaloids， terpenoids， flavonoids， and sterols， and treat GA through multi-component， multi-pathway， and multi-target mechanisms. Ermiaosan primarily exerts anti-inflammatory effects by inhibiting pathways such as TLR4/nuclear factor kappa-B （NF-κB） or regulating immune responses to reduce the release of inflammatory mediators， while also suppressing xanthine dehydrogenase （XDH） and xanthine oxidase （XO） activity to decrease uric acid production. Sanmiaowan enhance uric acid-lowering and anti-inflammatory effects through the guiding herb Cyathulae Radix， while also protecting cartilage from damage. Simiaowan utilizes Coicis Semen to regulate intestinal flora， alleviate dampness-heat symptoms， and exert multi-pathway anti-inflammatory and uric acid-lowering effects. The active ingredients contribute differently to uric acid metabolism regulation， anti-inflammation， antioxidant activity， and bone repair， resulting in varying therapeutic effects due to differences in formula composition. In summary， formulas derived from Ermiaosan demonstrate significant efficacy in treating dampness-heat type GA. This review summarizes their research progress and mechanisms， providing a reference for clinical application， new drug development， and further studies.

OBJECTIVE: To investigate the mechanism of human embryonic stem cell-derived mesenchymal stem cells (hESC-MSC) in alleviating brain injury after resuscitation in swine with cardiac arrest (CA). METHODS: Twenty-nine healthy male large white swine were randomly divided into Sham group (n = 9), cardiopulmonary resuscitation (CPR) group (n = 10) and hESC-MSC group (n = 10). The Sham group only completed animal preparation. In CPR group and hESC-MSC group, the swine model of CA-CPR was established by inducing ventricular fibrillation for 10 minutes with electrical stimulation and CPR for 6 minutes. At 5 minutes after successful resuscitation, hESC-MSC 2.5×10⁶/kg was injected via intravenous micropump within 1 hour in hESC-MSC group. Venous blood samples were collected before resuscitation and at 4, 8, 24, 48 and 72 hours of resuscitation. The levels of neuron specific enolase (NSE) and S100B protein (S100B) were detected by enzyme linked immunosorbent assay (ELISA). At 24, 48 and 72 hours of resuscitation, neurological deficit score (NDS) and cerebral performance category (CPC) were used to evaluate the neurological function of the animals. Three animals from each group were randomly selected and euthanized at 24, 48, and 72 hours of resuscitation, and the hippocampus tissues were quickly obtained. Immunofluorescence staining was used to detect the distribution of hESC-MSC in hippocampus. Immunohistochemical staining was used to detect the activation of astrocytes and microglia and the survival of neurons in the hippocampus. The degree of apoptosis was detected by TdT-mediated dUTP nick end labeling (TUNEL). RESULTS: The serum NSE and S100B levels of brain injury markers in CPR group and hESC-MSC group were significantly higher than those in Sham group at 24 hours of resuscitation, and then gradually increased. The levels of NSE and S100B in serum at each time of resuscitation in hESC-MSC group were significantly lower than those in CPR group [NSE (μg/L): 20.69±3.62 vs. 28.95±3.48 at 4 hours, 27.04±5.56 vs. 48.59±9.22 at 72 hours; S100B (μg/L): 2.29±0.39 vs. 3.60±0.73 at 4 hours, 2.38±0.15 vs. 3.92±0.50 at 72 hours, all P < 0.05]. In terms of neurological function, compared with the Sham group, the NDS score and CPC score in the CPR group and hESC-MSC group increased significantly at 24 hours of resuscitation, and then gradually decreased. The NDS and CPC scores of hESC-MSC group were significantly lower than those of CPR group at 24 hours of resuscitation (NDS: 111.67±20.21 vs. 170.00±21.79, CPC: 2.33±0.29 vs. 3.00±0.00, both P < 0.05). The expression of hESC-MSC positive markers CD73, CD90 and CD105 in the hippocampus of hESC-MSC group at 24, 48 and 72 hours of resuscitation was observed under fluorescence microscope, indicating that hESC-MSC could homing to the damaged hippocampus. In addition, compared with Sham group, the proportion of astrocytes, microglia and apoptotic index in hippocampus of CPR group were significantly increased, and the proportion of neurons was significantly decreased at 24, 48 and 72 hours of resuscitation. Compared with CPR group, the proportion of astrocytes, microglia and apoptotic index in hippocampus of hESC-MSC group decreased and the proportion of neurons increased significantly at 24 hours of resuscitation [proportion of astrocytes: (14.33±1.00)% vs. (30.78±2.69)%, proportion of microglia: (12.00±0.88)% vs. (27.89±5.68)%, apoptotic index: (12.89±3.86)% vs. (52.33±7.77)%, proportion of neurons: (39.44±3.72)% vs. (28.33±1.53)%, all P < 0.05]. CONCLUSIONS Application of hESC-MSC at the early stage of resuscitation can reduce the brain injury and neurological dysfunction after resuscitation in swine with CA. The mechanism may be related to the inhibition of immune cell activation, reduction of cell apoptosis and promotion of neuronal survival.

Innovative drugs are defined as new chemical entities that play a vital role in the treatment and maintenance of human health. While single-target innovative drugs have achieved notable success, they face limitations in addressing the increasingly complex and precise spectra of diseases. The advent of multi-target innovative drugs offers new opportunities, supported by a growing body of pharmacological evidence. Herbal medicines are recognized as valuable sources of multi-target therapeutics due to their proven efficacy in treating complex diseases. However, the identification and validation of such drugs from herbal sources continue to pose significant challenges. This paper presents a comprehensive review of the literature on traditional Chinese medicine, integrated medicine, chemistry, and biology from 2015 to 2025. It summarizes the strategies employed in integrating traditional Chinese and Western medicine for innovative drug development, along with successful application cases. We believe these efforts will deepen understanding of the current landscape, accelerate the discovery of multi-target innovative drugs from herbal medicine, and contribute to addressing major human health challenges.

Acute lung injury （ALI） is one of the most common and critical diseases in clinical practice， with extremely high morbidity and mortality， seriously threatening human life and health. The pathogenesis of ALI is complex， in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 （NLRP3） inflammasomes are involved in ALI through mechanisms such as inflammation induction， increased microvascular permeability， recruitment of neutrophils， oxidative stress， and pyroptosis， playing a key role in the occurrence and progression of ALI. Therefore， regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present， ALI is mainly treated by mechanical ventilation and oxygen therapy， which have problems such as high costs and poor prognosis. In recent years， studies have shown that traditional Chinese medicine （TCM） can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome， thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years， this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes， discusses how NLRP3 inflammasomes participate in ALI， and summarizes the active ingredients， extracts， and compound prescriptions of TCM that regulate NLRP3 inflammasomes， aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

Objective:To determine the expression and diagnostic value of peripheral blood lymphocytes and functional activation status in non-Hodgkin lymphoma with hemophagocytic lymphohistiocytosis (NHL-HLH) .Methods:We retrospectively analyzed clinical data from 30 newly diagnosed NHL-HLH patients admitted to Jiangsu Province Hospital from September 2022 to September 2023. We assessed peripheral blood lymphocytes and activation status by flow cytometry. Forty newly diagnosed patients with NHL who received treatment at our hospital during the same period and had lymphocyte and functional activation indexes were selected as the control group. The differences in relative and absolute lymphocyte counts and functional activation indexes between the two groups were compared. The optimal cutoff values for continuous variables were calculated from the receiver operating characteristic curve and logistic regression analysis was used to evaluate the risk factors in NHL patients with HLH.Results:A total of 30 NHL-HLH patients were evaluated, including 12 T-cell lymphoma and 18 B-cell lymphoma patients. Forty individuals were in the control group, which included 19 T-cell lymphoma and 21 B-cell lymphoma patients. The absolute counts of CD3 + T, CD4 + T, CD8 + T, and NK cells, along with the relative count of NK cells, were significantly lower in the HLH group compared with that in the control group (all P values<0.01) . The expression of CD38 and HLA-DR on CD8 + T-cell activated subgroups was significantly higher in the NHL-HLH group compared with that in the control group (CD8 +CD38 +/CD8 + T expression median: 57.4% vs 21.5%, P<0.001; CD8 +CD38 +/CD8 + T expression median: 49.7% vs 33.5%, P=0.028, respectively) . In addition, CD28 expression on CD4 + and CD8 + T cells was significantly higher in NHL-HLH patients ( P<0.01) . ROC curve and multivariate logistic regression analyses revealed that absolute NK cell count ≤72.0 cells/μl, CD4 +CD28 +/CD4 + T >94.2%, and CD8 +CD28 +/CD8 + T >38.4% were risk factors for predicting the occurrence of NHL-HLH patients. The sensitivity and specificity of the regression model were 86.7% and 86.1%, respectively, with an area under the curve of 0.94 ( P<0.001) . Conclusions:In NHL patients with HLH, there was a significant reduction in the absolute number of peripheral blood lymphocyte subpopulations, whereas T-cell function was notably activated. Specifically, absolute counts of NK cells ≤72.0 cells/μl, CD4 +CD28 +/CD4 + T >94.2%, and CD8 +CD28 +/CD8 + T >38.4% were identified as risk factors for predicting the development of NHL-HLH patients. This will assist in early clinical diagnosis and treatment.

Objective:To explore the protective efficacy of sulforaphane (SFN) in alleviating intestinal mucosal injury after resuscitation in pigs and its possible mechanism.Methods:This experiment was performed in the laboratory animal center, Zhejiang university. Using a random number table, twenty-four domestic healthy male white pigs were randomly divided into the Sham group, cardiopulmonary resuscitation (CPR) group, and SFN group, in which the Sham group had 6 pigs, and the other two groups had 9 pigs, respectively. The experimental parameters of 10 min of cardiac arrest and 6 min of CPR were chosen to establish the porcine model of CPR in the CPR and SFN groups. At 5 min after resuscitation, a dose of 2 mg/kg of SFN was infused via the femoral vein within 10 min in the SFN group. At 1 h, 2 h, 4 h, and 24 h after resuscitation, vein samples were collected, and then the levels of intestinal fatty acid binding protein (IFABP) and diamine oxidase (DAO) in serum were measured by ELISA. Subsequently, 6 pigs were chosen to be euthanized in each group, and then tissue samples were harvested from distal ileum to measure the level of cell apoptosis by TUNEL, the activities of superoxide dismutase (SOD) and catalase (CAT) and the contents of glutathione (GSH) and malondialdehyde (MDA) by biochemical method, the contents of 4-hydroxy-2-nonenal (4-HNE) by ELISA, the fluorescence intensity of reactive oxygen species (ROS) by immunofluorescence staining, and the expression levels of zonula occluden-1 (ZO-1), occludin, nuclear factor E2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) by Western blot. Continuous variables were compared with one way analysis of variance among the three groups, and Bonferroni test was used for further pairwise comparison.Results:During the observation period after resuscitation, the serum levels of biomarkers of intestinal mucosal injury including IFABP and DAO were significantly higher in the CPR and SFN groups than in the Sham group (all P<0.05). However, the serum levels of IFABP at 2 h, 4 h, and 24 h after resuscitation and the serum levels of DAO at 1 h, 2 h, 4 h, and 24 h after resuscitation were significantly lower in the SFN group than in the CPR group (all P<0.05). At 24 h after resuscitation, apoptotic index was significantly increased, SOD and CAT activities and GSH contents were significantly decreased, MDA and 4-HNE contents and ROS production were significantly increased, ZO-1 and occludin expression were significantly down-regulated, and Nrf2 and HO-1 expression were significantly up-regulated in the CPR and SFN groups when compared with the Sham group (all P<0.05). However, apoptotic index was significantly decreased, SOD and CAT activities and GSH contents were significantly increased, MDA and 4-HNE contents and ROS production were significantly decreased, and ZO-1, occludin, Nrf2, and HO-1 expression were significantly up-regulated in the SFN group when compared to the CPR group (all P<0.05). Conclusion:SFN could effectively protect against intestinal mucosal injury after resuscitation in pigs, and its mechanism was possibly related to the inhibition of oxidative stress and cell apoptosis via the activation of Nrf2/HO-1 pathway.

Objective:To establish pig cardiac arrest resuscitation model, and explore the effect of automatic compression synchronous ventilation (ACSV) on cardiopulmonary resuscitation in pigs.Methods:Twelve male white pigs with body weight of (38±3) kg were divided into ACSV group and intermittent positive pressure ventilation (IPPV) group with 6 pigs in each group by random number table method. A porcine cardiac arrest and resuscitation model was prepared with ventricular fibrillation induced by alternating current release via right ventricular electrode for 6 min and compression for 8 min. Mechanical chest external compression depth 5 cm, frequency 100 times/min. The tidal volume of ACSV group was 3 mL/kg and the frequency was 100 times/min. In the IPPV group, the tidal volume was 7 mL/kg and the frequency was 10 times/min. Arterial blood was drawn before resuscitation and at 1, 4 and 7min during resuscitation for blood gas analysis. Coronary perfusion pressure (CPP), end-respiratory carbon dioxide (ETCO 2) and carotid blood flow (CBF) were monitored during resuscitation. Stroke volume (SV) and global ejection fraction (GEF) were recorded by pressure monitoring catheter before and 1, 2 and 4 h after resuscitation. Venous blood samples were collected at each time point and 24 h after resuscitation to detect cardiac troponin I (cTnI), neuron specific enolase (NSE), alamine aminotransferase (ALT), creatinine (Cr), and intestinal fatty acid binding protein (IFABP). Results:(1) During resuscitation, CPP, ETCO 2 and CBF in ACSV group were slightly higher than those in IPPV group, but the differences between groups were not statistically significant. (2) There was no significant difference in pH, PaCO 2, HCO 3- and lactic acid between the two groups during resuscitation. The PaO 2 in ACSV group was higher than that in IPPV group, and the difference was statistically significant at 4 and 7 min. (3) The success rate of resuscitation in both groups was 83.3%, and there was no significant difference in SV and GEF before and after resuscitation. (4) After resuscitation, cTnI, NSE, ALT, Cr, iFABP and other indexes in ACSV group were lower than those in IPPV group, and there were statistically significant differences in cTnI at 24 h after resuscitation, ALT at 2 h and 24 h after resuscitation, and IFABP at 4 h and 24 h after resuscitation (all P<0.05). Conclusions:This study preliminarily suggested that the novel ACSV could significantly improve the oxygen supply level during cardiopulmonary resuscitation in pigs, while keeping the compression efficiency unchanged, avoiding hyperventilation, and reducing multiple organ damage after resuscitation, which is worthy of further study.

Objective To explore prokaryotic expression,purification of hemolysin coregulatory protein(Hcp)of Vibrio cholerae,and preparation of its polyclonal antibodies.Methods PCR was used to amplify Vibrio cholerae Hcp gene and clone it into pET28a vector to construct recombinant expression vector.The recombinant vector pET28a-hcp was transformed into E.coil BL21(DE3)for expression condition optimization and expression form identification.The soluble Hcp protein was purified by Ni-NTA column.The purified Hcp protein was used to immunize BALB/c mice to prepare polyclonal antibodies.The antibody titer was detected by indirect enzyme-linked immunosorbent assay(ELISA)to evaluate its immunogenicity.Western blot was used to analyze the specific recognition of antibodies to Hcp protein in Vibrio cholerae.Results The enzyme fragment digested by recombinant vector pET28a-hcp was consistent with the expected,the sequencing results were consistent with the Hcp gene sequence in the GenBank database,and the pET28a-hcp recombinant plasmid was successfully constructed.The recombinant plasmid was induced by isopropyl-β-D-thiogalactopyranoside(IPTG)to express the target protein with a relative molecular weight of 28 kD.The pure Hcp protein was obtained after purification by Ni-NTA column,and then Hcp polyclonal antibody(anti-Hcp)with a titer of 1∶512 000 could be obtained from immunized mice.Western blot results showed that anti-Hcp had specificity in recognizing Hcp protein in Vibrio cholerae.Conclusion The soluble expression of Hcp protein is successfully obtained,and high-titer polyclonal antibodies against Hcp are obtained after immunization of mice,which may lay a foundation for subsequent studies on the role of Hcp protein in the pathogenesis of T6SS in non-O1/non-O139 V.cholerae.
