Pan-cancer analyses reveal genomics and clinical outcome association of the fatty acid oxidation regulators in cancer.

Background: Fatty acid oxidation (FAO) is considered to play a vital part in tumor metabolic reprogramming. But the comprehensive description of FAO dysregulation in tumors has not been unknown. Methods: We obtained FAO genes, RNA-seq data and clinical information from the Msigdb, TCGA and GTEx databases. We assessed their prognosis value using univariate cox analysis, survival analysis and Kaplan-Meier curve. We determined the function of FAO genes using gene set variation analysis. The correlation analysis was calculated by corrplot R package. Immunotherapy response was assessed through TIDE scores. The protein expression levels of FAO genes were validated using immunohistochemistry (IHC). Results: The FAO scores were highest in COAD but lowest in PCPG. FAO scores were significantly associated with the prognosis of some cancers in OS, DSS, DFI and PFI. Besides, gene set variation analysis identified that FAO scores were related to immune-related pathways, and immune infiltration analysis showed FAO scores were positively related to cancer-associated fibroblasts and various immune-related genes. TIDE scores were significantly decreased in ACC, CHOL, ESCA, GBM, LAML, SARC, SKCM and THCA compared with normal samples, while it was significantly increased in BLCA, LUAD, LUSC, PCPG, PRAD and STAD. Besides, most FAO genes were downregulated in pan-cancer compared with normal samples. Moreover, we found copy number variation (CNV) of FAO genes played a positive role in their mRNA expression, while methylation was negative. We determined FAO genes were closely related to some drugs in pan-cancer. Conclusions: FAO score is a novel and promising factor for predicting outcomes.

Extending the Grading of Recommendations Assessment, Development and Evaluation (GRADE) in Traditional Chinese Medicine (TCM): The GRADE-TCM.

AIM: To extend and form the "Grading of Recommendations Assessment, Development and Evaluation in Traditional Chinese Medicine" (GRADE-TCM). METHODS: Methodologies were systematically reviewed and analyzed concerning evidence-based TCM guidelines worldwide. A survey questionnaire was developed based on the literature review and open-end expert interviews. Then, we performed expert consensus, discussion meeting, opinion collection, external examination, and the GRADE-TCM was formed eventually. RESULTS: 265 Chinese and English TCM guidelines were included and analyzed. Five experts completed the open-end interviews. Ten methodological entries were summarized, screened and selected. One round of consensus was conducted, including a total of 22 experts and 220 valid questionnaire entries, concerning 1) selection of the GRADE, 2) GRADE-TCM upgrading criteria, 3) GRADE-TCM evaluation standard, 4) principles of consensus and recommendation, and 5) presentation of the GRADE-TCM and recommendation. Finally, consensus was reached on the above 10 entries, and the results were of high importance (with voting percentages ranging from 50 % to 81.82 % for "very important" rating) and strong reliability (with the Cr ranging from 0.93 to 0.99). Expert discussion meeting (with 40 experts), opinion collection (in two online platforms) and external examination (with 14 third-party experts) were conducted, and the GRADE-TCM was established eventually. CONCLUSION: GRADE-TCM provides a new extended evidence-based evaluation standard for TCM guidelines. In GRADE-TCM, international evidence-based norms, characteristics of TCM intervention, and inheritance of TCM culture were combined organically and followed. This is helpful for localization of the GRADE in TCM and internationalization of TCM guidelines.

[Bacterial Community Diversity in Channel Sediments of Different Disturbance Sections of the Jialing River].

In order to explore the impact of different anthropogenic disturbances on the ecological environment of natural rivers, the bacterial community in the channel sediments of the Jialing River was taken as the research object, and the high-throughput sequencing technique was used to analyze the community composition and functional changes of bacteria in the channel sediments of rivers with engineering disturbance, tributary disturbance, sand mining disturbance, reclamation disturbance, and undisturbed section. The results showed that there were significant differences in the physical and chemical properties of channel sediments and bacterial community diversity in different disturbance sections of the Jialing River (P<0.05). The undisturbed section had the highest bacterial community diversity, whereas the sand mining disturbance and undisturbed section had the highest bacterial community uniformity, and tributary disturbance and reclamation disturbance both resulted in a decrease in bacterial community diversity and uniformity. The effect of engineering disturbance on bacterial community composition was significantly different from that of the other four disturbance sections. The dominant bacterial phyla were Proteobacteria, Actinobacteriota, Acidobacteriota, and Chloroflexi, and the dominant bacterial classes were γ-Proteobacteria, α-Proteobacteria, and Vicinamibacteria. Sand mining disturbance led to the increase in Actinobacteria, and engineering disturbance promoted the increase in Acidobacteria. Moisture content, total organic carbon, total nitrogen, and total phosphorus were the main environmental factors affecting the changes in sediment microbial communities. The bacterial communities mainly involved four categories of primary metabolic functions, including metabolism, genetic information processing, environmental information processing, and cellular processes, and 18 categories of secondary metabolic functions, such as global and overview maps, carbohydrate metabolism, amino acid metabolism, cofactor and vitamin metabolism, and energy metabolism. Human interference led to significant changes in energy metabolism, cofactor and vitamin metabolism, nucleotide metabolism, replication and repair, and translation (P<0.05). In conclusion, anthropogenic disturbance led to the mutation of bacterial community diversity and function, which destroyed the stability of the microbial community structure in Jialing River sediments.

A novel CDKN1A-JAZF1 gene fusion in low-grade endometrial stromal sarcoma arising from endometriosis in abdominal wall cesarean section scar: A case report and literature review.

OBJECTIVE: We report a low-grade endometrial stromal sarcoma (ESS) with a novel CDKN1A-JAZF1 fusion gene arising from abdominal wall endometrioma. CASE REPORT: A 40-year-old woman presented with a 5.5-cm abdominal wall mass juxtaposed to the postoperative scar of two cesarean sections. Histologically, the tumor exhibited obvious tongue-like protrusions into the surrounding tissue, showed spindle cells with multinodular growth pattern that occasionally rotate around small arteries. Immunohistochemically, the tumor cells were positive for CD10, estrogen receptor (ER), progesterone receptor (PR), negatively stained for smooth muscle actin (SMA), CD117, CyclinD1. In addition, a previously undescribed gene fusion between CDNK1A 5' end of exon 1(NM_000389.5) and JAZF1 3' end of exon 5 (NM_175,061,3) was reported in this case. CONCLUSION: This report of ESS suggesting that rapidly growing abdominal wall masses without menstruation-related should be promptly evaluated and treated aggressively. In addition, we have expanded the molecular landscape of low-grade ESS.

[Effect of Different Land Use Types on the Diversity of Soil Bacterial Community in the Coastal Zone of Jialing River].

The purpose of this study was to clarify the differences in soil bacterial community diversity in different land uses in the coastal zone of the Jialing River and to provide theoretical reference for reasonable land development and resource protection of the Jialing River basin. Based on second generation high-throughput sequencing technology, the diversity, structural composition, functional types, and influencing factors of soil bacterial communities in different land use types were analyzed. The results showed that:① there were some differences in soil physical and chemical properties among different land uses. The nutritional indexes of agricultural land and soil wetland were significantly higher than those of natural forest land and sandy soil wetland (P<0.05). ②The Ace, Shannon, and Chao indexes of sandy soil wetland and soil wetland were significantly higher than those of natural forest land and agricultural land (P<0.05). The Simpson index of soil bacteria in different land use types was significantly different (P<0.05). ③ The dominant phyla of soil bacteria in the coastal zone of the Jialing River were Proteobacteria, Actinobacteriata, Acidobacteriata, and Chloroflexi, and the relative abundance accounted for more than 65%. The community structure of sandy soil wetland was similar to that of soil wetland and was significantly different from that of other land use types (P<0.05). ④ Primary functional metabolism was the core function of the bacterial community, accounting for more than 75%. Agricultural activities had the greatest impact on the community function, which significantly improved the metabolism of amino acids and carbohydrates, enhanced the utilization of nitrogen and phosphorus, reduced the metabolism of energy and coenzyme vitamins, and weakened the resistance of bacterial community to environmental impact (P<0.05). ⑤ Total phosphorus (TP) was the key influencing factor of the soil bacterial community. In conclusion, the construction of the wetland habitat in the Jialing River coastal zone is most conducive to the development of underground ecological diversity and the stability of the soil ecosystem.

Combination of Preoperative D-Dimer and Platelet Distribution width Predicts Postoperative Deep Venous Thrombosis in Patients with Cervical Carcinoma

Background: Deep venous thrombosis (DVT) is associated with severe morbidity and mortality in cancer. Platelet distribution width (PDW), a platelet index, indicates variation in platelet size. We aimed to investigate whether the combination of D-dimer and PDW could have a better performance in predicting DVT in patients with cervical carcinoma. Materials and Methods: In 198 consecutive cervical carcinoma patients without preoperative DVT, preoperative D-dimer and PDW levels were measured. Compression ultrasonography was performed in all cervical carcinoma patients before surgery, as well as one month, three months, six months, and 12 months. Results: During a median period of 12 months, 17 of the 198 patients (8.6 %) developed DVT. PDW levels were reduced and D-dimer levels were increased in patients with DVT events compared to those without DVT. Multivariate Cox analysis revealed that both PDW and D-dimer were independent predictors for DVT events. The area under the ROC curve was 0.628 (95% CI: 0.556 to 0.695, p=0.142) when D-dimer was used alone, whereas it increased to 0.777 (95% CI: 0.712 to 0.833, p<0.011) with the addition of PDW. Incorporation of PDW into the D-dimer model significantly improved the predictive value. Conclusions: The combination of preoperative D-dimer and PDW improves the predictive power of postoperative DVT risk in patients with cervical carcinoma.
