To better capture the local geometric structural information of 3D point clouds, an adaptive graph convolutional 3D point cloud recognition algorithm is proposed based on attention mechanism. To address the drawback of fixed convolutional kernels ignoring features, the algorithm first dynamically learns adaptive convolutional kernels based on graph structural features. Furthermore, to enhance the modeling capability of the model for local geometric structures, the weight distribution of the convolutional kernels using a vector attention mechanism is adjusted adaptively. Subsequently, a graph is constructed using the position features of the point cloud and perform convolution operations on the newly constructed graph structural features using the adaptive convolutional kernels. Finally, new point cloud features through pooling is obtained. Experimental results demonstrate that the proposed algorithm effectively extracts local geometric structural information and achieves higher accuracy in classification tasks even with a limited number of sampled points, outperforming previous point cloud convolutional algorithms. The proposed algorithm also exhibits certain advantages compared to existing methods for point cloud classification and segmentation, as evidenced by the performance evaluation on the ModelNet40, ScanObjectNN, and ShapeNetPart datasets.

Objective To analyze the mortality trend of lung cancer in Sichuan Province from 2007 to 2021, and provide evidence for formulating lung cancer prevention and control policies in the new period. Methods Lung cancer mortality was obtained from Health Statistics Yearbook of Sichuan Province, A cohort age 一 period model was used to estimate the effect of age, period and birth cohort on lung cancer mortality in residents aged 20 一 84. Results The mortality rates of lung cancer in male and female increased from 59. 68/100 000 and 16. 48/100 000 in 2007 to 75. 14/100 000 and 30. 49/100 000 in 2021 respectively. Compared with residents aged 20 -24, male and female residents aged 75 - 79 were 101 times and 121 times higher than those aged 20-24 respectively; male and female lung cancer mortality risks from 2017 to 2021 were 1. 29 times and 1. 31 times higher than those from 2012 to 2016 respectively; male and female lung cancer mortality risks bom in 1927一 1931 were 73.42 times and 38.49 times higher than those born in 1992一1996 respectively. Conclusion Lung cancer mortality in Sichuan Province fluctuates from 2007 to 2021, and male mortality is higher. There were differences in lung cancer mortality risk by age, period, and birth cohort.

Objective The prognostic significance of chondroitin polymerization factor 2 (CHPF2) in glioma was analyzed by bioinformatics technology, and its expression in normal and glioma cells was further verified by experiments. Methods The expression levels of CHPF2 in glioma and normal cells were first analyzed in the GEPIA and HPA databases, followed by downloading gene expression and clinical information files from The Cancer Genome Atlas (TCGA) and The Chinese Glioma Genome Atlas (CGGA) to further elucidate the expression, prognosis, functional annotation, immune infiltration, and immune checkpoints of CHPF2 in glioma. Finally, the expression levels of CHPF2 in normal and glioma tissues were determined using the Western blotting approach. Results CHPF2 expression in gliomas was greater than in normal tissues, and it increased with tumor grade. Except for gender, radiation, and tumor recurrence, the high and low CHPF2 expression groups differed statistically in age, chemotherapy, tumor recurrence, IDH, 1p/19q, and MGMT. CHPF2 outperforms certain popular prognostic markers (e.g. TP53, MKI67, and EGFR) in predicting glioma patient survival and may be utilized as an independent prognostic factor. A complete meta-analysis of the outcomes of separate prognostic analysis of the TCGA and CGGA databases corroborated this further. GO, KEGG, and GSEA techniques were used to examine the pathways for which CHPF2 may be enriched. Initially, three approaches (TIMER, CIBERSORT, and ssGSEA) were utilized to investigate immune infiltration in the high and low-risk groups of CHPF2, and finally, the immunological checkpoints of CHPF2 were examined. To further corroborate the dependability, Western blotting was used to demonstrate the elevated expression of CHPF2 in gliomas relative to normal tissues. Conclusion CHPF2 may be able to influence the occurrence, progression and prognosis of glioma and may serve as a biomarker for the prognosis of glioma patients. [ABSTRACT FROM AUTHOR]

BACKGROUND: There is a lack of the research concerning the biocompatibility of nano-hydroxyapatite/polyphenylene sulfide (nHA/PPS) composites. OBJECTIVE: To evaluate the in vivo biocompatibility of nHA/PPS composites based on the completed research in vitro. METHODS: Systemic toxicity test: Sprague-Dawley rats were given the intraperitoneal injection of nHA/PPS extract or normal saline. The general situation, body mass and the histological changes of the liver and kidney were observed at 72 hours after injection. Delayed type hypersensitivity test: nHA/PPS extract or normal saline was injected subcutaneously into the back of the rats. Afterwards, skin irritation symptoms were observed at 72 hours. Local reaction experiment: nHA/PPS composites and polyethylene were respectively implanted into the back of the rats. The pathological changes of the implanted materials and their surrounding tissues were observed at 15 and 30 days after implantation. RESULTS AND CONCLUSION: (1) The rats were in good situation after nHA/PPS injection; the body mass increased steadily, which showed no significant difference from the control group (P < 0.05); the morphology and color of the liver and kidney were normal, and the systemic toxicity of the composite materials was normal according to the degree of toxicity classification. (2) There were no obvious skin irritation symptoms after the subcutaneous injection of nHA/PPS composites, and the primary irritation index was less than 0.4, suggesting a low hypersensitivity. After implantation of nHA/PPS composites, there was no obvious degradation, absorption and rejection, and both the degree of inflammatory reaction (15 days ≤ level III, 30 days ≤ level II) and the thickness of fibrous capsule (15 days ≤ level III, 30 days ≤ level II) revealed the good biocompatibility of the composites. These results suggest that the nHA/PPS composites hold an excellent biocompatibility in vivo. [ABSTRACT FROM AUTHOR]
