Objective: To investigate the characteristics of malignant tumor incidence and mortality in cancer registration areas of Sichuan Province in 2021. Methods: Cancer registration data from 142 registries in Sichuan Province in 2021 were collected via the China Cancer Registry Platform. Crude incidence and crude mortality were calculated. The Chinese population-standardized incidence and world population-standardized incidence were standardized using the age structure of the standard population from the Fifth National Population Census in 2000 and Segi's world standard population. Descriptive analyses examined the distribution of rates by genders, urban/rural areas, and ages, and the ranking of leading cancer sites. Results: In 2021, there were 248 600 new malignant tumor cases reported in Sichuan Province, with a crude incidence of 296.37/100 000. The Chinese population-standardized incidence and world population-standardized incidence were 164.67/100 000 and 160.47/100 000, respectively. There were 158 673 malignant tumor deaths, with a crude mortality of 189.16/100 000. The Chinese population-standardized mortality and world population-standardized mortality were 92.47/100 000 and 92.00/100 000, respectively. The Chinese population-standardized incidence and mortality in males were higher than in females (179.56/100 000 vs. 151.62/100 000, 125.09/100 000 vs. 60.35/100 000). The Chinese population-standardized incidence and mortality in urban areas were higher than in rural areas (175.74/100 000 vs. 157.54/100 000, 93.63/100 000 vs. 91.82/100 000). Both the crude incidence and crude mortality increased with age. The top ten malignant tumors by crude incidence were lung cancer, colorectal cancer, liver cancer, breast cancer, esophageal cancer, gastric cancer, cervical cancer, prostate cancer, thyroid cancer, and corpus uteri cancer, accounting for 76.33% of all new cases. The top ten by crude mortality were lung cancer, liver cancer, esophageal cancer, colorectal cancer, gastric cancer, breast cancer, pancreatic cancer, cervical cancer, prostate cancer, and brain tumors, accounting for 82.39% of all cancer deaths. Conclusions In registration areas of Sichuan Province, the incidence and mortality of malignant tumors are relatively low. Key populations such as males, urban residents, and the elderly require focused prevention and control efforts. Comprehensive measures should be prioritized for malignant tumors including lung cancer, liver cancer, esophageal cancer, gastric cancer, colorectal cancer, and breast cancer.

Based on ultra-high performance liquid chromatography-quadrupole-Exactive Orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) technology and network pharmacology, this study explored the pharmacodynamic substances and potential mechanisms of Huazhuo Sanjie Chubi Decoction in the treatment of gouty arthritis(GA). UPLC-Q-Exactive Orbitrap-MS technology was used to identify the components in Huazhuo Sanjie Chubi Decoction, and the qualitative analysis of its active ingredients was carried out, with a total of 184 active ingredients identified. A total of 897 active ingredient targets were screened through the PharmMapper database, and 491 GA-related disease targets were obtained from the OMIM, GeneCards, CTD databases. After Venn analysis, 60 intersecting targets were obtained. The component target-GA target network was constructed through the Cytoscape platform, and the STRING database was used to construct a protein-protein interaction network, with 16 core targets screened. The core targets were subjected to Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses, and the component-target-pathway network was constructed. It was found that the main active ingredients of the formula for the treatment of GA were phenols, flavonoids, alkaloids, and terpenoids, and the key targets were SRC, MMP3, MMP9, REN, ALB, IGF1R, PPARG, MAPK1, HPRT1, and CASP1. Through GO analysis, it was found that the treatment of GA mainly involved biological processes such as lipid response, bacterial response, and biostimulus response. KEGG analysis showed that the pathways related to the treatment of GA included lipids and atherosclerosis, neutrophil extracellular traps(NETs), IL-17, and so on. In summary, phenols, flavonoids, alkaloids, and terpenoids may be the core pharmacodynamic substances of Huazhuo Sanjie Chubi Decoction in the treatment of GA, and the pharmacodynamic mechanism may be related to SRC, MMP3, MMP9, and other targets, as well as lipids and atherosclerosis, NETs, IL-17, and other pathways.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

OBJECTIVE: To investigate the clinical effect and adverse reactions of dapoxetine hydrochloride versus paroxetine in the treatment of primary premature ejaculation by cross-comparison. METHODS: Based on the clinic-visit time, we equally randomized 148 patients with primary premature ejaculation into groups A and B for a cross-comparison test, the former treated with paroxetine at 20 mg once nightly and the latter with dapoxetine hydrochloride at 30 mg on demand, both for 6 successive weeks, during which we observed the therapeutic effects and adverse reactions. Following 4 weeks of drug discontinuance, we administered dapoxetine hydrochloride at 30 mg on demand for group A and paroxetine at 20 mg once nightly for group B, both for another 6 successive weeks, followed by observation and comparison of the therapeutic effects and adverse reactions. RESULTS: There were no statistically significant differences in the initial characteristics of the two groups of patients (P > 0.05). Compared with the baseline, the mean intra-vaginal ejaculation latency time (IELT) was dramatically improved after treatment in both groups A (4.43 min) and B (7.12 min), increased by 3.99% and 6.72%, respectively (P<0.001). The patients treated with paroxetine showed significantly longer IELT than those taking dapoxetine hydrochloride in both groups (P<0.001). Findings of the Premature Ejaculation Profile (PEP) and spouses' conditions indicated significant improvement after treatment in the average scores of the four indicators of PEP, that is, perceived control over ejaculation, ejaculation-related personal distress, satisfaction with sexual intercourse and ejaculation-related interpersonal difficulty, as well as in the overall experience and partner's satisfaction and orgasm frequency. Adverse reactions to medication were found in 20.8% of the cases in group A and 9.7% in group B, but none was serious. Preference survey following drug withdrawal revealed a preference for paroxetine (61.9%) over dapoxetine (26.8%), and that only a few of the patients thought of the two drugs as comparable or both ineffective. CONCLUSION In term of overall effectiveness, paroxetine was superior to dapoxetine in the treatment of primary premature ejaculation. And the patients obviously preferred the former to the latter, which might be partly attributed to the higher price of dapoxetine.

Objective To analyze the epidemic characteristics of pneumoconiosis in Jingmen City from 2011 to 2022, and to provide theoretical basis for formulating the occupational disease prevention plan of the ^“14th Five-Year Plan^” in Jingmen City. Methods The data of pneumoconiosis cases in Jingmen City from 2011 to 2022 were collected from the Occupational Disease and Health Hazard Factors Monitoring Information System, and the information of disease classification, enterprise economic type, scale distribution, regional distribution, job distribution, dust exposure years and so on was statistically analyzed. Results A total of 260 cases of pneumoconiosis were reported in Jingmen City from 2011 to 2022, with an average of 13.81 years of exposure to dust, including 164 cases of coal workers' pneumoconiosis, 90 cases of silicosis and 6 cases of other pneumoconiosis. The cases were mainly distributed in Dongbao District with 160 cases (61.54%), Zhongxiang City with 72 cases (27.69%), and Duodao District with 18 cases (6.92%). The difference was statistically significant（χ²=217.846，P<0.05）. The cases were mainly distributed in private enterprises (76.54%, 199 cases). The enterprise sizes were mainly medium-sized (28.46%, 74 cases) and small (61.15%, 159 cases) enterprises, and the difference was statistically significant (χ²=46.025，P<0.05). Conclusion Coal workers' pneumoconiosis and silicosis are the main types of occupational pneumoconiosis in Jingmen area, which will become the key prevention and control targets in Jingmen City for a long time and should be paid attention to. The cases are mainly concentrated in joint-stock, private economic type enterprises and small and medium-sized enterprises, which should be monitored intensively.

Objective: To investigate the molecular mechanism and identify potential drugs for subthreshold depression (SD), and elucidate the detalied mechanism of Danzhi Xiaoyao powder (DZXY) in SD. Methods: Using RNA-sequencing, we identified differentially expressed genes (DEGs) in leukocytes of SD compared to healthy controls, deciphered their functions and pathways, and identified the hub genes of SD. We also assessed changes in leukocyte transcription factor activity in patients with SD using the TELiS platform. The Connectivity Map database was retrieved to screen candidate drugs for SD. Based on network pharmacology, we elucidated the “multi-component, multi-target, and multi-pathway” mechanism of DZXY in the treatment of SD. Results: We identified 1080 DEGs (padj <0.05 and |log2 (fold change)| ≥ 1 & protein coding) in the leukocytes of patients with SD. These DEGs, including hub genes, were primarily involved in immune and inflammatory response-related processes. Transcription factor activity analysis revealed similarities between the leukocyte transcriptome profile in SD and the conserved transcriptional response to adversities in immune cells. Connectivity Map analysis identified 28 potential drugs for SD treatment, particularly SB-202190 and TWS-119. Constructing the “Direct Compounds-Direct Targets-Pathways” network for DZXY and SD revealed the curative mechanisms of DZXY in SD, primarily including inflammatory response, lipid metabolism, immune response, and other processes. Conclusion These results provide new insights into the characteristics and functional changes of leukocytes in SD, partially illustrate the pathogenesis of SD, and suggest potential drugs for SD. The curative mechanisms of DZXY in SD are also partially elucidated.

The implementation of amplicon sequencing and metagenomic sequencing methods in the whole-genome sequen-cing for MPXV testing was compared,to provide a technical reference for sequencing,tracing,and epidemic prevention and control of MPXV.For amplicon sequencing,targeted amplification of the viral whole genome was performed on MPXV DNA,and was followed by next-generation sequencing of the amplification products.For metagenomic sequencing,next-generation sequencing was performed directly on MPXV DNA.After the sequences were obtained,software such as CLC and IGV were used to analyze the effective data percentage,sequencing depth,and whole-genome sequencing coverage under different sequen-cing depths for both sequencing methods,to evaluate sequencing quality.Nextclade was used to analyze virus typing,muta-tions,and deletions.Subsequently,the similarity and completeness of sequences obtained through both sequencing methods were further compared.On the basis of mapping to the refer-ence sequence of strain MPXV-M5312_HM12_Rivers(Gen-Bank number NC_063383.1),the percentage effective data obtained from amplicon sequencing and metagenomic sequen-cing was 99.72％and 7.54％,respectively,with a sequencing depth range of 0× to 334 839 ×,and 44 × to 1 000 ×.On the basis of a sequencing depth of 10 ×,the site coverage of the above was 90.3％and 100％,respectively.IGV was used to validate the whole-genome coverage under different sequencing depths.The depth coverage of whole-genome sites for metagenomic sequencing was uniform,whereas that of the whole-genome sites for amplicon sequencing was uneven and significantly differed.Virus typing and sequence similarity analysis indicated that the viral sequences obtained with the two sequencing methods all belonged to the Ⅱb B.1 lineage of MPXV.Comparison with the reference sequence indicated that metagenomic sequencing identified 73 nucleotide mutation sites,whereas amplicon sequen-cing identified 68 mutation sites.Further analysis demonstrated that seven common mutation sites of Ⅱb B.1 were not detected in the amplicon sequencing,and two false positive private mutation sites were identified.Amplicon or metagenomic sequencing methods thus can be flexibly used in MPXV virus whole-genome sequencing.Amplicon sequencing yields more effective data,whereas metagenomic sequencing provides better uniformity of coverage and sequence accuracy.This study provides a prelimi-nary understanding of the efficacy of each method and may serve as a technical reference for improving the success rate of whole-genome sequencing of MPXV.

Objective:This study explored the designs of physicians'compensation incentives that were compatible with the reform of Diagnosis-related groups(DRG)payment,so as to provide a reference for optimizing policies related to medical insurance payment reform.Methods:We designed seven different physicians'compensation schemes that converted DRG payment incentives into salary incentives,using economic experiments.The total of 210 medical students and 65 doctors were recruited as subjects.We tested the quantity of medical services for patients that participants provided and the corresponding patient health benefits under different incentive schemes.Results:The two designs of feedback of DRG payment to physicians and linking DRG payment surplus to physicians'performance wages both could transmit the incentive of the payment methods to the service providers.On this basis,a quality-based pay-for-performance payment was introduced,and the deviation between the quantity of services provided by subjects and the optimal quantity of services decreased,and the loss ratio of patient health benefits also decreased.Conclusion:When transmitting DRG payment incentives to medical service providers,the physician compensation design combined with quality-based pay-for-performance payments is more conducive to improving patient health benefits.

Objective To investigate the changes in cerebral blood flow(CBF)and whole-brain functional connectivity(FC)in patients with neuromyelitis optica spectrum disorder(NMOSD)examined by conventional MRI.Methods Twenty-two patients with NMOSD and 25 matched healthy controls(HC)were included,and all subjects'conventional MRI sequences,arterial spin labeling(ASL),and resting-state functional magnetic resonance imaging(rs-fMRI)image data were acquired,and the brain regions with CBF differences between groups extracted based on ASL were used as seed points for whole-brain FC analysis,the FC differences between the groups were compared,and the correlation between the parameter values and the expanded disability status scale(EDSS)scores were analyzed.Results NMOSD patients exhibited a decrease in CBF value in the right supratemporal gyrus,bilateral calcarine fissure and right supplementary motor area,while the right middle temporal gyrus displayed an increase when compared to HC.Whole-brain FC analysis based on seed points revealed an increase in FC value between bilateral calcarine fissure and olfactory cortex,as well as between right supplementary motor area and left superior frontal gyrus.While FC value between the right supplementary motor area and left precentral gyrus,bilateral thalamus,right supraoccipital gyrus were decreased.The FC value between the right supratemporal gyrus and right inferior parietal lobule,left supratemporal gyrus,right precuneus lobes showed a decrease[Gaussian random field(GRF)-corrected,P＜0.05].There was a correlation between CBF values of bilateral calcarine fissure and EDSS scores in NMOSD patients(rs=-0.456,P=0.033).Conclusion There are CBF and FC abnormalities in multiple brain regions in NMOSD patients,which provide imaging basis and insights for the brain micropathological changes of NMOSD,and help to understand the pathology and neural mechanism of NMOSD.
