ObjectiveThis paper aims to verify the therapeutic effect of Cranial Painkiller pills' extract powder prepared by the new process on the rat's trigeminal neuralgia model caused by infraorbital injection of Talci Pulvis, evaluate its potential clinical application value, and compare the therapeutic effect with that of Cranial Painkiller granules, so as to provide data support for the application of the Cranial Painkiller pills' extract powder and precise treatment. MethodsThe rat's trigeminal neuralgia model was constructed by infraorbital injection of Talci Pulvis, and the rats were randomly divided into the normal group, model group, carbamazepine group (60 mg·kg-1), Cranial Painkiller granules group (2.70 g·kg-1), and low, medium, and high dosage groups of Cranial Painkiller pills' extract powder (1.35, 2.70, 5.40 g·kg-1) according to the basal mechanical pain thresholds, and there were 10 rats in each group. The drug was administered by gavage to each group 2 h after modeling, and distilled water was given by gavage to the normal and model groups under the same conditions once a day for 10 d. Von Frey brushes were used to measure mechanical pain thresholds in rats. Hematoxylin-eosin (HE) staining was used to detect pathological changes in the trigeminal ganglion, and enzyme-linked immunosorbent assay (ELISA) was used to detect the inflammatory factors interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) levels in rat serum, as well as neuropeptide substance P (SP) and β-endorphin (β-EP) levels in rat brain tissue. Western blot technique was used to detect the levels of NLRP3, ASC, Caspase-1, and OTULIN proteins in rat brain tissue. ResultsCompared with the normal group, the pain threshold of rats in the model group showed a continuous significant decrease (P<0.01). The pathological damage of brain tissue was significant (P<0.01), and the inflammatory levels of IL-1, IL-6, IL-8, and TNF-α in serum were significantly elevated (P<0.01).

Objective:
To estimate the incidence and mortality of lung cancer in 2021 and their trends from 2014 to 2021 within cancer registration areas of Inner Mongolia Autonomous Region, so as to provide the basis for formulating localized strategies for lung cancer prevention and control.
Methods:
The data on lung cancer cases in cancer registration areas of Inner Mongolia Autonomous Region in 2021 were collected from the China Cancer Registration, encompassing data from 55 registries within the region. Crude incidence and crude mortality were calculated by genders, urban/rural rareas, and ages. The Chinese population-standardized rate was calculated using the age structure of the standard population from the Fifth National Population Census in 2000, while the world population-standardized rate was calculated using Segi's world standard population. To assess the trends in Chinese population-standardized incidence and mortality of lung cancer from 2014 to 2021, data from nine qualifying cancer registries were analyzed using the average annual percent change (AAPC).
Results:
In 2021, within Inner Mongolia Autonomous Region, the crude, Chinese population-standardized, and world population-standardized incidences of lung cancer were 58.96/100 000, 31.58/100 000, and 31.50/100 000, respectively. The crude, Chinese population-standardized, and world population-standardized mortalities were 46.48/100 000, 24.65/100 000, and 24.36/100 000 , respectively. The Chinese population-standardized incidence and mortality of lung cancer were 1.59-fold and 1.88-fold higher in males compared to females, and 1.08-fold and 1.10-fold higher in urban areas relative to rural areas. The crude incidence and mortality of lung cancer reached their peaks at age of 80-<85 years (379.91/100 000 and 474.31/100 000, respectively). From 2014 to 2021, the Chinese population-standardized incidence of lung cancer in Inner Mongolia Autonomous Region decreased from 43.28/100 000 to 31.41/100 000, showed a downward trend (AAPC=-3.312%, P<0.05), while the Chinese population-standardized mortality decreased from 31.55/100 000 to 24.11/100 000, showed no statistical significance (P>0.05). The Chinese population-standardized incidence of lung cancer in the group aged ≥75 years and the Chinese age-standardized mortality of lung cancer in the group aged 0-<45 years showed declining trends (AAPC=-4.307%, -7.355%, both P<0.05).
Conclusions
The disease burden of lung cancer in cancer registration areas of Inner Mongolia Autonomous Region has decreased, showing characteristics where the burden is higher in males than in females and slightly higher in urban areas than in rural areas. The elderly population represents a key group for lung cancer prevention and control.

Microwave thermochemotherapy (MTC) has been applied to treat lip squamous cell carcinoma (LSCC), but a deeper understanding of its therapeutic mechanisms and molecular biology is needed. To address this, we used single-cell transcriptomics (scRNA-seq) and spatial transcriptomics (ST) to highlight the pivotal role of tumor-associated neutrophils (TANs) among tumor-infiltrating immune cells and their therapeutic response to MTC. MNDA+ TANs with anti-tumor activity (N1-phenotype) are found to be abundantly infiltrated by MTC with benefit of increased blood perfusion, and these TANs are characterized by enhanced cytotoxicity, ameliorated hypoxia, and upregulated IL1B, activating T&NK cells and fibroblasts via IL1B-IL1R. In this highly anti-tumor immunogenic and hypoxia-reversed microenvironment under MTC, fibroblasts accumulated in the tumor front (TF) can recruit N1-TANs via CXCL2-CXCR2 and clear N2-TANs (pro-tumor phenotype) via CXCL12-CXCR4, which results in the aggregation of N1-TANs and extracellular matrix (ECM) deposition. In addition, we construct an N1-TANs marker, MX2, which positively correlates with better prognosis in LSCC patients, and employ deep learning techniques to predict expression of MX2 from hematoxylin-eosin (H&E)-stained images so as to conveniently guide decision making in clinical practice. Collectively, our findings demonstrate that the N1-TANs/fibroblasts defense wall formed in response to MTC effectively combat LSCC.

Journal of Clinical Hepatology 2024;40(2):298-305
ObjectiveTo investigate the value of platelet-albumin-bilirubin index (PALBI) combined with AIMS65 score in predicting rebleeding and death within 6 weeks after admission in patients with liver cirrhosis and acute upper gastrointestinal bleeding (AUGIB). MethodsA retrospective study was conducted for 238 patients with liver cirrhosis and AUGIB who were hospitalized in The First Affiliated Hospital of Jinzhou Medical University from February 2021 to October 2022, and all patients were followed up for 6 weeks. According to the prognosis, they were divided into death group with 65 patients and survival group with 173 patients, and according to the presence or absence of rebleeding, they were divided into non-rebleeding group with 149 patients and rebleeding group with 89 patients. General data and laboratory markers (including blood routine, liver/renal function, and coagulation), and PALBI, AIMS65 score, Child-Turcotte-Pugh (CTP) score, and Model for End-stage Liver Disease (MELD) score were calculated on admission. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. A multivariate logistic regression model analysis was used to investigate the risk factors for death or rebleeding within 6 weeks after admission in patients with liver cirrhosis and AUGIB. The receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were used to investigate the predictive efficacy of each scoring system, and the DeLong test was used for comparison of AUC. ResultsThere were significant differences between the death group and the survival group in hematemesis, past history of varices, albumin (Alb), total bilirubin (TBil), international normalized ratio (INR), creatinine (Cr), prothrombin time (PT), systolic blood pressure, PALBI, AIMS65 score, CTP score, and MELD score (all P<0.05). The multivariate logistic regression analysis showed that hematemesis (odds ratio [OR]=4.34, 95% confidence interval [CI]: 1.88 — 10.05, P<0.001), past history of varices (OR=3.51, 95%CI: 1.37 — 8.98, P=0.009), PALBI (OR=4.49, 95%CI: 1.48 — 13.64, P=0.008), and AIMS65 score (OR=3.85, 95%CI: 2.35 — 6.30, P<0.001) were independent risk factors for death. The ROC curve analysis of each scoring system in predicting survival showed that CTP score, MELD score, PALBI, AIMS65 score, and PALBI combined with AIMS65 score had an AUC of 0.758, 0.798, 0.789, 0.870, and 0.888, respectively, suggesting that PALBI combined with AIMS65 score had a significantly larger AUC than the four scoring systems used alone (all P<0.05). There were significant differences between the rebleeding group and the non-rebleeding group in hematemesis, history of diabetes, Alb, TBil, INR, Cr, PT, PALBI, AIMS65 score, CTP score, and MELD score (all P<0.05). The multivariate logistic regression analysis showed that PALBI (OR=2.41, 95%CI: 1.17 — 4.95, P=0.017) and AIMS65 score (OR=1.58, 95%CI: 1.17 — 2.15, P=0.003) were independent risk factors for rebleeding. The ROC curve analysis of each scoring system in predicting rebleeding showed that CTP score, MELD score, PALBI, AIMS65 score, and PALBI combined with AIMS65 score had an AUC of 0.680, 0.719, 0.709, 0.711, and 0.741, respectively, suggesting that PALBI combined with AIMS65 score had the largest AUC (all P<0.05), but with a relatively low specificity. ConclusionPALBI combined with AIMS65 score has a certain value in predicting death within 6 weeks after admission in patients with liver cirrhosis and AUGIB, with a better value than CTP score and MELD score alone. PALBI combined with AIMS65 score has a relatively low value in predicting rebleeding within 6 weeks, with an acceptable accuracy.

ObjectiveTo investigate the intervention effect of Jiedu Tongluo Tiaogan prescription (JTTP) in protecting pancreatic β cells by targeting the bile acid Takeda G protein-coupled receptor 5 (TGR5)/cyclic adenosine monophosphate (cAMP) signaling pathway against NOD-like receptor protein 3 (NLRP3) inflammasome. MethodThirty-two male SPF-grade db/db mice were randomly divided into the model group, low-dose JTTP group (3.6 g·kg-1), high-dose JTTP group (7.2 g·kg-1), and metformin group (0.2 g·kg-1). Eight db/m mice were assigned to the blank control group. The mice were treated with drugs for 8 weeks, and fasting blood glucose (FBG) was measured every 2 weeks. Oral glucose tolerance tests (OGTT) were conducted after the last administration. Enzyme-linked immunosorbent assay (ELISA) was performed to detect fasting insulin (FINS), and the homeostasis model assessment of β-cell function (HOMA-β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-1β levels were calculated. Hematoxylin-eosin (HE) staining was used to observe pathological changes in mouse pancreatic tissue. Immunofluorescence was performed to detect insulin expression in mouse pancreatic tissue. Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were used to detect the expression of proteins and mRNAs of key targets in the TGR5/cAMP signaling pathway and NLRP3 inflammasome. ResultCompared with blank group, FBG, OGTT, FINS, IL-6, TNF-α and IL-1β in model group were significantly increased (P<0.01). Compared with model group, after 6 weeks of drug treatment, FBG level in JTTP group and metformin group decreased significantly (P<0.01). The results of OGTT experiment showed that compared with model group, the blood glucose levels of mice in each administration group were decreased at all time points (P<0.05, P<0.01), and the levels of FINS, TNF-α and IL-6 in JTTP dose groups and metformin group were significantly decreased. The level of IL-1β in JTTP high-dose group and metformin group was significantly decreased (P<0.01). Pancreatic pathology showed that the islets in the model group were irregular in shape, uneven in distribution, and showed signs of atrophy. The prognosis of JTTP was that the cell count increased and the boundary was clearer. Immunofluorescence results showed that the islet cells in the blank group were arranged in an orderly and full shape with appropriate insulin secretion, while the islet cells in model group were distorted in shape, atrophy in structure and less insulin secretion. The insulin content of mice in JTTP and metformin group was significantly increased. Compared with blank group, mRNA expressions of NLRP3, apoptosis-related spot-like protein (ASC) and Caspase-1 in pancreatic tissues of model group were significantly increased (P<0.01). Compared with model group, JTTP high-dose group and metformin group promoted the up-regulation of TGR5 and cAMP mRNA, and down-regulated the mRNA expressions of NLRP3, ASC and Caspase-1 (P<0.05, P<0.01). Compared with blank group, the expression of TGR5 protein in model group was significantly decreased (P<0.01). Compared with model group, TGR5 protein in JTTP high-dose group and metformin group was significantly increased (P<0.01).

The complex chemical composition and limited research ideas of traditional Chinese medicine (TCM) have led to the unclear material basis and mechanism of the medicinal effects, which is a common problem hindering the modernization of TCM in China. The introduction of computer virtual technology has provided a new perspective for TCM research. In this study, we established the research method of structure-activity omics to study the relationships between the structures and effects of different compounds in TCM based on the chemical structures of TCM components and to analyze and predict the material basis and multitarget synergistic mechanism of TCM. Furthermore, a structure-activity omics study was carried out with the anti-inflammatory and analgesic effects of Qizhi Weitong granules as an example. This study provides support for screening the pharmacodynamic components and analyzing the active ingredients of TCM and gives insights into the research on the material basis and mechanism of compound efficacy and the development of lead compounds of TCM, thus promoting the modern research and the innovative development of TCM.

ObjectiveTo explain the anti-inflammatory and analgesic effects of Corydalis Rhizoma by the means of structure-activity omics. MethodOn the basis of the previous in vitro screening study, we studied the in vivo efficacy of the alkaloids in Corydalis Rhizoma. With the targets as a bridge, the structures of chemical components in Corydalis Rhizoma were connected with the efficacy. The molecular docking of the alkaloids in Corydalis Rhizoma with the targets of inflammation and pain was carried out. According to the docking scores and the differences in the structural nucleus of Corydalis Rhizoma alkaloids, a study of structure-activity omics was carried out to summarize the rules of their connection. ResultThe alkaloids in Corydalis Rhizoma had good anti-inflammatory and analgesic effects in vivo, involving 53 chemical components and 73 targets. There were 3 074 targets associated with inflammation and pain, and 42 targets of direct action were shared by the chemical components and the disease. The protein-protein interaction (PPI) and molecular docking analysis predicted that the main active components of Corydalis Rhizoma were tetrahydropalmatine and palmatine, and the core targets were prostaglandin endoperoxide synthase 2 (PTGS2), glutamate receptor metabotropic 5 (GRM5), estrogen receptor 1 (ESR1), solute carrier family 6 member 4 (SLC6A4), and fusion oncoproteins (FOS). According to the differences of mother nucleus, the 53 alkaloid components of Corydalis Rhizoma were classified into 8 categories, including protoberberine, berberine, and aporphine, which had high binding affinities with PTGS2, GRM5 and other targets. The relationship between the structures of Corydalis Rhizoma alkaloids and docking scores in each group showed the same law. In protoberberine, appropriate substituents with hydroxyl, alkoxy or methyl groups on the A and D rings of the parent ring were conducive to enhancing the binding activities with the two targets. In berberine, the structure containing a methyl group on position 13 had strong binding affinities with the two targets. It is hypothesized that the methyl fragment changes the binding mode between the component structure and amino acid residues, which greatly improves the binding affinity. ConclusionThis study employs the method of structure-activity omics to analyze the material basis for the anti-inflammatory and analgesic effects of alkaloids in Corydalis Rhizoma, and the structure-activity omics provides new ideas for revealing the pharmacodynamic substances of traditional Chinese medicine.
