Objectives To investigate the clinical characteristics and prognosis of bone metastasis of gastric cancer, analyze the influencing factors of bone metastasis and the effects of different treatment methods, and provide a basis for early detection and treatment optimization of bone metastasis of gastric cancer. Methods A total of 142 gastric cancer patients with bone metastasis admitted to the First Hospital of Lanzhou University from January 2011 to December2021 were enrolled, including 60 cases of simple bone metastasis and 82 cases of bone metastasis combined with extraosseous metastasis. 142 patients with stage Ⅲ gastric cancer without distant metastasis and 142 gastric cancer patients with visceral metastasis admitted to this hospital during the same period were also enrolled for comparison. Logistic regression analysis was used to determine the influencing factors of bone metastasis, and the Cox proportional hazards regression model was used to evaluate the influencing factors of overall survival (OS) of patients with bone metastasis. Results Among the 142 patients with bone metastasis, poorly differentiated adenocarcinoma was the main type (123 cases), and 45 patients had simultaneous bone metastasis. Rib metastasis (100 cases), spine metastasis (88 cases), and pelvis metastasis (84 cases) were more common. A total of 110 patients had multiple bone metastasis, and 82 patients had extraosseous metastasis. Results of the stage Ⅲ gastric cancer group, the visceral metastasis group, the bone metastasis group, and the bone metastasis with extraosseous metastasis group were compared. There were significant differences in age, degree of differentiation, Borrmann type, alkaline phosphatase, lactate dehydrogenase, serum calcium, alanine aminotransferase, aspartate aminotransferase, creatine kinase isoenzyme, lymphocyte, hemoglobin, platelet, CEA, CA19-9, and CA724 (all P<0.05). Multivariate logistic regression analysis showed that Borrmann type was an independent protective factor of bone metastasis of gastric cancer (type 3: OR=0.07, 95%CI: 0.01-0.64, P=0.018). Alkaline phosphatase (OR=2.54, 95% CI: 1.07-6.01, P=0.034), serum calcium (OR=2.71, 95% CI: 1.15-6.41, P=0.023), creatine kinase isoenzyme (OR=16.33, 95% CI: 1.83-145.58, P=0.012), platelet (OR=10.08, 95% CI: 1.89-53.85, P=0.007), and CA19-9 (OR=2.40, 95% CI: 1.14-5.05, P=0.021) were independent risk factors of bone metastasis of gastric cancer. The median OS of the stage Ⅲ gastric cancer group, the visceral metastasis group, the bone metastasis group, and the bone metastasis with extrabony group were 47, 13, 18, and 6 months, respectively, and the difference was statistically significant (P<0.001). The median OS of patients with bone metastasis only who underwent primary tumor surgery was 33 months, better than 6 months of patients without surgery (P=0.048). Multivariate Cox regression analysis showed that extraosseous metastasis (HR=2.45, 95% CI: 1.56-3.85, P<0.001) and decreased hemoglobin (HR=1.54, 95%CI: 1.02-2.34, P=0.042) were independent risk factors of OS of gastric cancer patients with bone metastasis. Conclusions The prognosis of gastric cancer patients with bone metastasis alone is significantly better than that of other stage Ⅳ patients. For such patients, surgery on the primary site combined with chemotherapy after full evaluation may prolong the survival time. [ABSTRACT FROM AUTHOR]

[Objective] The study explored the distribution of antibiotic resistance genes (ARGs) in mangroves and the association between microorganisms and ARGs in order to understand the current situation of mangrove resistance pollution and provide theoretical support for risk assessment of ARGs in the environment. [Method) Metagenomics technique was used to explore the composition, diversity and relationship with microorganisms of antibiotic resistance genes in mangrove sediments and water in Dongzhaigang, Hainan province. [Result] The rifampicin resistance gene rpoB mutants, daptomycin resistance gene rpoC, fluoroquinolone resistance gene mfd, aminocoumarin resistance gene alas, acetoxy resistance gene EF-Tu mutants, macrolide resistance gene macB and isoniazid resistance gene katG were dominant genes in this area. The composition types of antibiotic resistance gene in sediment and water were similar, but the diversities of antibiotic resistance gene in water were higher than those in sediment. However, NMDS analysis showed that the composition and distribution of ARGs in sediments and water bodies were obviously different. The correlation analysis between ARGs and microbial groups showed that α-Proteobacteria, γ-Proteobacteria, β-Proteobacteria and Flavobacteriia were the main microbial groups strongly associated with ARGs, accounting for 70%. Among them, the resistance genes in water were mainly distributed in α-Proteobacteria, β-Proteobacteria and Flavobacteriia, while the resistance genes in sediments were mainly distributed in γ-Proteobacteria and δ-Proteobacteria. (Conclusion) Mangrove sediments and water bodies have different composition characteristics of ARGs, and they both have different risk characteristics. As a result, when carrying out ecological monitoring and management of drug-resistant microorganisms and ARGs in mangroves, attention should be paid not only to monitoring the compositional characteristics of microorganisms, but also to the pattern of change of ARGs in the water body, in order to predict the risk of drug-resistance of microorganisms in sediment in this area of mangroves in Dongzhaigang, Hainan.

[Objective] To explore the inhibitory effect of hiocontrol strain JT86 on sclerotia-producing pathogens of tobacco. [Methods] The cell wall hydrolase activities in the fementation broth of Pseudomonas aeruginosa 186 were detected using the double-antibody sandwich method. The mycelium and sclerotia morphological changes of the pathogen treated with JT86 fermentation broth were observed using scanning electron microscopy. The inhibitory effects on the hyphal growth and clematia germination of Rhizoctonia solani, Sclerotium ralf, and Sclerotinia sclerotiarum were tested. [Results] The inhibitory rates of JT86 fermentation broth on the hyphal growth of R. salani 5. rolfsii and S. sclerotiaru w 77.07% 50.82% and 95.25% respectively. After 24 h treatment with JT86 fermentation broth, the sclerotia of the three pathogens did not germinate, with inhibitory rates all reached 100% JT86 fermentation houth had high protease, cellulase and chitinase activities, but did not produce indoleacetic acid. Scanning electron microscopy showed that JT86 fermentation broth could cause severe hyphal atrophy and deformity of R. zolani. [Conclusion] The JT86 fermentation both had good inhibitory effects on the growth and development, as well as selestial germination of R. solani, S. ralfiii and S. scleratiorum.

BACKGROUND: Intrusion of overerupted posterior teeth with clear aligner for adult patients with different bone densities, orthodontists mostly choose the diaphragm thickness by subjective experience, and finite element analysis is expected to provide a theoretical basis for choosing the appropriate thickness of diaphragms for patients with different bone densities. OBJECTIVE: To analyze the effects of diaphragm thickness and bone density on the intrusion of overerupted maxillary first molar in adult patients using clear aligners using finite element analysis. METHODS: Four groups of finite element models were created based on four bone densities (cancellous bone types I, II, III, and IV) and assembled with three clear aligner models with diaphragm thicknesses of 0.5, 0.75, and 1 mm, respectively. Finite element analysis was then performed using Ansys 2021 software. Clear aligners applied a 0.2 mm intrusion displacement to the maxillary first molar was simulated in each group. The von Mises stress and tooth displacement trends of root, periodontal ligament, alveolar bone of first molar and its adjacent teeth were compared between groups. RESULTS AND CONCLUSION: (1) The von Mises stress distribution of the first molar was the same in all groups, mainly at the root furcation; the second premolar was distributed in the proximal mid-cervical 1/3; the second molar was distributed at the buccal root furcation. (2) The displacement of the first molar and adjacent teeth was close to mesial displacement; the first molar displayed a buccal displacement trend, whereas adjacent teeth displayed a palatal displacement trend. At class II density of alveolar bone, the first molar X- and Y-axis displacement was the smallest, and the Z-axis displacement was the greatest; displacement of adjacent teeth increased with decreasing bone density. In the Z-axis direction, the displacement of the first molar and adjacent teeth was proportional to the thickness of the diaphragm. The smallest displacement was observed in the second premolar 1 mm and second molar 0.5 mm groups in the X- and Y-axis directions. (3) These results concluded that the use of clear aligners to lower the overerupted molars is less likely to cause pericemental fibrosis and root resorption. Decreased bone density does not increase the risk of root resorption. Class II bone density is optimal for molar intrusion. The maximum equivalent stress of the periodontal ligament and alveolar bone is proportional to the thickness of the diaphragm. [ABSTRACT FROM AUTHOR]

Objective To assess the clinical significance of 16p13.11 microduplications encompassing NDE1 gene and study the genotype-phenotype correlation. Methods Sixty-one patients and 6, 144 controls who had undergone chromosome microarray analysis（CMA）for neurocognitive impairment or other reasons were analyzed and then divided into three groups: a group of patients with neurocognitive impairment, a prenatal group with abnormal nervous systems, and a prenatal group with normal nervous systems. The fetuses carrying 16p13.11 microduplications were followed up, and the detection rates for the three groups were statistically analyzed. Results 16p13.11 microduplications were not detectable in the group of patients with neurocognitive impairment and the prenatal group with abnormal nervous systems. However, 16p13.11 microduplications encompassing NDE1 gene were detectable in 13 fetuses in the prenatal group with normal nervous systems. Of these, one pregnancy was terminated because of fetal heart defect, the others chose to continue their pregnancy, and no other structural abnormalities were observed in the fetuses. A follow-up on postnatal health of the newborns revealed no apparent abnormalities. There was no significant difference in the detection rate of 16p13.11 microduplication among the three groups （P > 0.05）. Conclusions Combined with the characteristics of low penetrance, 16p13.11 microduplications encompassing the entire NDE1 gene may be benign variants;however, more large-scale studies are needed to evaluate the associated clinical phenotypes. Follow-up to adulthood is recommended for prenatal cases with 16p13.11 microduplication. [ABSTRACT FROM AUTHOR]

Objective To provide further data for clinical treatment of rare autosomal trisomy (RATs), through the analysis of the results of RATs screened by non-invasive prenatal examination (NIPT). Method A total of 85, 525 pregnant women who received NIPT in Maternity and Child Health Hospital Affiliated to Anhui Medical University from January 1, 2018 to June 1, 2022 were selected. Invasive diagnosis was performed for women with high risk results and pregnancy outcome was followed. Result Among the 85, 525 samples, 182 cases of high risk of RATs were detected. A total of 136 cases chose for further diagnosis, and 7 cases were confirmed, including 2 cases of T2, 1 case of T7, 1 case of T9, 1 case of T15, and 2 cases of T16. Positive predictive value (PPV) were 50%, 3.13%, 12.5%, 33.3%, and 12.5%, respectively, and the PPV of other chromosomes was 0. The total PPV was 5.15%. Detailed follow-up was conducted in 121 high-risk pregnant women, and 116 (95.87%) had a live birth, the incidence of fetal growth restriction (FGR) and preterm birth (PTB) were 25.62%, 20.66% respectively. Conclusion RATs screened by NIPT has a lower PPV, but the high risk of RATs has important clinical significance, suggesting that pregnant women are at increased risk of FGR and PTB and need enhanced ultrasound follow-up.
