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.

Objective:To explore the clinical and genetic characteristics of a child with mental retardation, language and motor developmental delay and epilepsy.Methods:A Child who was admitted to the First Affiliated Hospital of Zhengzhou University in March 2020 for intermittent seizures for over two months was Selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and his parents were collected and subjected to high throughput sequencing. Candidate variants were verified by Sanger sequencing and bioinformatic analysis.Results:The clinical manifestations of the child have included mental retardation, language and motor developmental delay, and seizures. High-throughput sequencing revealed that he has harbored a hemizygous splice site variant (NM_032591.3: c.1030-1G>C) of the SLC9A7 gene, which was inherited from his mother and unreported previously. Conclusion:The hemizygous splice site variant (NM_032591.3: c. 1030-1G>C) of the SLC9A7 gene probably underlay the disease in this child. Above finding has provided a basis for clinical diagnosis and genetic counseling.

Objective:To explore the association between polymorphisms of transforming growth factor-β(TGF-β)signaling pathway and non-syndromic cleft lip with or without cleft palate(NSCL/P)among Asian populations,while considering gene-gene interaction and gene-environment interaction.Methods:A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P.After stringent quality control measures,343 single nucleotide polymorphism(SNP)spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS)dataset for further analysis.The transmission disequilibrium test(TDT)was used to test for SNP effects.The conditional Logistic regression models were used to test for gene-gene interaction and gene-environment interaction.Environmental factors collected for the study in-cluded smoking during pregnancy,passive smoking during pregnancy,alcohol intake during pregnancy,and vitamin use during pregnancy.Due to the low rates of exposure to smoking during pregnancy and al-cohol consumption during pregnancy(<3%),only the interaction between maternal smoking during pregnancy and multivitamin supplementation during pregnancy was analyzed.The threshold for statistical significance was rigorously set at P=1.46 × 10-4,applying Bonferroni correction to account for multiple testing.Results:A total of 23 SNPs in 4 genes yielded nominal association with NSCL/P(P<0.05),but none of these associations was statistically significant after Bonferroni's multiple test correction.How-ever,there were 6 pairs of SNPs rs4939874(SMAD2)and rs1864615(TGFBR2),rs2796813(TGFB2)and rs2132298(TGFBR2),rs4147358(SMAD3)and rs1346907(TGFBR2),rs4939874(SMAD2)and rs1019855(TGFBR2),rs4939874(SMAD2)and rs12490466(TGFBR2),rs2009112(TGFB2)and rs4075748(TGFBR2)showed statistically significant SNP-SNP interaction(P<1.46 × 10-4).In contrast,the analysis of gene-environment interactions did not yield any significant results after being cor-rected by multiple testing.Conclusion:The comprehensive evaluation of SNP associations and interac-tions within the TGF-β signaling pathway did not yield any direct associations with NSCL/P risk in Asian populations.However,the significant gene-gene interactions identified suggest that the genetic architec-ture influencing NSCL/P risk may involve interactions between genes within the TGF-β signaling path-way.These findings underscore the necessity for further investigations to unravel these results and further explore the underlying biological mechanisms.
