Objective:To analyze the recovery of olfactory function in patients diagnosed with chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery and to identify factors influencing recovery to provide a theoretical foundation for taking effective measures.Methods:This was a retrospective analysis included 277 CRSwNP patients with olfactory dysfunction who underwent endoscopic sinus surgery at the First Affiliated Hospital of Chongqing Medical University from October 2021 to September 2023. This study included 189 males and 88 females, with a median age of 46 years (range: 18-84 years). Routine laboratory tests, sinus CT Lund-Mackay score, modified sinus CT score, endoscopic polyp score, and nasal endoscopic Lund-Kennedy score were included for preoperative assessments. Eosinophil counts were obtained from nasal polyp tissues during surgery. The University of Pennsylvania smell identification test (UPSIT) was administered before surgery and 6 months after surgery to evaluate olfactory function. Based on results of postoperative olfactory test, patients were divided into two groups: the group with improved olfactory function and without improvement of olfactory function. Chi-square test and multivariate Logistic regression were used to analyze relevant factors affecting postoperative olfactory function of CRSwNP patients, and the prediction model was constructed to verify its consistency and to analyze its prediction efficiency.Results:Of the 277 patients, 155 (56%) showed improved olfactory function and 122 (44%) did not improve after surgery. Multivariate Logistic regression analysis identified following independent factors associated with improved postoperative olfactory function: concurrent allergic rhinitis ( OR=2.34), long duration of olfactory dysfunction ( OR=1.13), higher total score of CT olfactory zone ( OR=1.26), higher Lund-Kennedy score ( OR=1.23), presence of olfactory cleft polyps ( OR=4.72), higher tissue eosinophil count ( OR=1.01) and high IL-6 levels ( OR=1.51). Conversely, a higher endoscopic polyp score ( OR=0.74) was associated with a lower likelihood of olfactory improvement. The nomogram model, validated using receiver operating characteristic (ROC) analysis, demonstrated good clinical efficacy with an area under the curve (AUC) of 0.80 (95%CI: 0.748-0.852). The calibration curve showed an absolute error of 0.021, indicating good consistency and predictive accuracy. Conclusions:Factors such as a medical history of allergic rhinitis, duration of olfactory dysfunction, total score of sinus CT olfactory zone, endoscopic Lund-Kennedy score, olfactory cleft polyps, tissue eosinophil count, IL-6 level and endoscopic polyp score independently influence postoperative olfactory function of CRSwNP patients. The nomogram model based on these independent factors has good clinical efficacy, which can be used to predict the postoperative olfactory function in CRSwNP patients with olfactory dysfunction.

Objective To explore the strategy of intrathoracic anastomosis in patients with esophageal squamous cell carcinoma when the proximal esophagus is dilated to different degrees and explore its mechanism. Methods We retrospectively reviewed the clinical data of patients who underwent esophagectomy between 2014 and 2017 in West China Hospital. The patients were divided into two groups including a significant dilatation group with inner mucosal phase diameter (IMPD)≥17.9 mm and a non-significant dilatation group with IMPD<17.9 mm. And the patients were divided into two groups (a layered manual anastomosis group and a stapled anastomosis group) according to anastomosis method and propensity score matching was applied to adjust for potential confounders. Results We finally included 654 patients. There were 206 patients with 158 males and 48 females at average age of 62.21±7.72 years in the layerd manual analstomosis group and 448 patietns with 377 males and 71 females at average age of 62.57±8.42 years in the stapled anastomosis group. We also used Masson trichrome staining to assess the collagen fiber content in the esophagus. Compared with layered manual anastomosis, the incidence of anastomotic leakage was higher in the significant dilatation group than that in the stapled anastomosis group (original cohort: 3.8% vs. 10.7%, P=0.093; propensity score-matched cohort: 1.4% vs. 15.3%, P=0.004). And there was no significant difference in anastomotic leakage b etween layered manual anastomosis and stapled anastomosis in the non-significant dilatation group (original cohort: 4.7% vs. 4.2%, P=0.830; propensity score-matched cohort: 4.8% vs. 4.0%, P=0.206). Moreover, the average collagen fiber area ratio was significantly lower in the significant dilation group than that in the non-significant dilatation group (P=0.045). Conclusion There is a significant reduction in collagen fibers in the proximal esophageal wall tissue of esophageal squamous cell carcinoma patients with a IMPD≥17.9 mm. Intrathoracic layered manual anastomosis effectively reduces postoperative anastomotic leakage in these patients.

Objective: To explore the relationship between adolescent sports participation and aggression, so as to provide a reference basis for sports interventions aimed at reducing adolescent aggression. Methods: The search databases used in the study included China National Knowledge Infrastructure, Vipo, Wanfang, Web of Science, Ebsco, Pro Quest, and PubMed, and the search period was from the construction of the database to October 22, 2023. The search terms for sports participation were "sport" "exercise" "exercise" "physical activity" "physical activity"; the search terms for aggressive behavior were "assault" "aggressive behavior" "aggression"; the search terms for aggressive behavior were "assault" "aggressive behavior" "aggression" "bullying", and "violence", and the above keywords were jointly searched. Foreign language data were searched using Web of Science, Ebsco, Pro Quest, PubMed and supplemented by Google Scholar. The search terms for sports participation were sport, athletics, exercise, train, fitness, physical exercise, physical activity, physical education; and the search terms for aggressive behavior were aggression, bullying, violence, atrocity, fighting, aggressive behavior, physical assault; the above keywords were jointly searched. Statistical analysis was performed using CMA 3.0 software. Results: A total of 20 studies with 80 effect sizes and 9 308 subjects were included. The Metaanalysis showed that adolescent sports participation was moderately negatively correlated with indicators of aggression (r=-0.11), physical aggression (r=-0.14), verbal aggression (r=-0.14), and hostility (r=-0.16), and weakly negatively correlated with indicators of anger (r=-0.08) (P<0.05). Aggressive behavior was influenced by gender, school stage, mode of exercise, and the sports participants region (P<0.05). Conclusions Exercise participation has a positive impact on reducing aggressive behavior in adolescents, and mode of exercise, age, gender, and region are moderating variables in the relationship. Schools can reduce adolescent aggression by developing exercise and physical education interventions.

Objective:To investigate the causal relationship between intestinal flora and benign biliary diseases by genome-wide Mendelian randomization.Methods:This is a retrospective observational study. The data from the genome-wide association study of the gut microbiota from 18 340 samples from the MiBioGen consortium were selected as the exposure group,and the data from the genome-wide association study of biliary tract diseases were obtained from the FinnGen consortium R8 as the outcome group. There were 1 491 cases of primary sclerosing cholangitis,32 894 cases of cholelithiasis,3 770 cases of acalculous cholecystitis,and 34 461 cases of cholecystitis. Single nucleotide polymorphisms were screened as instrumental variables,and the Mendelian randomization method was used to infer the causal relationship between exposures and outcomes. The inverse variance weighting method (IVW) was used as the main basis, supplemented by heterogeneity,pleiotropy and sensitivity tests.Results:Coprococcus 2 was associated with a reduced risk of cholelithiasis (IVW OR=0.88,95% CI:0.80 to 0.97, P=0.012) and cholecystitis (IVW OR=0.88,95% CI:0.80 to 0.97, P=0.011). Coprococcus 3 was associated with cholelithiasis (IVW OR=1.15,95% CI:1.02 to 1.30, P=0.019) and acalculous cholecystitis(IVW OR=1.48, 95% CI: 1.08 to 2.04, P=0.016) and cholecystitis (IVW OR=1.17, 95% CI: 1.02 to 1.33, P=0.020). Peptococcus was associated with an increased risk of cholelithiasis (IVW OR=1.08, 95% CI:1.02 to 1.13, P=0.005) and cholecystitis (IVW CI=1.07, 95% CI:1.02 to 1.13, P=0.010). Clostridiumsensustricto 1 was associated with an increased risk of cholelithiasis (IVW OR=1.16,95% CI:1.02 to 1.31, P=0.020) and cholecystitis (IVW OR=1.16, 95% CI:1.03 to 1.30, P=0.015). Eubacterium hallii was associated with an increased risk of primary sclerosing cholangitis (IVW OR=1.43, 95% CI: 1.03 to 1.99, P=0.033). Eubacterium ruminantium (IVW OR=0.87, 95% CI: 0.76 to 1.00, P=0.043) and Methanobrevibacter (IVW OR=0.81, 95% CI: 0.68 to 0.98, P=0.027) were associated with a reduced risk of acalculous cholecystitis. Conclusions:Eight intestinal bacterial genera maybe play pathogenic roles in benign biliary diseases. Eubacterium hallii can increase the risk of primary sclerosing cholangitis. Peptococcus and Clostridiumsensustricto 1 can increase the risk of cholelithiasis and generalized cholecystitis. Coprococcus 3 have multiple correlations with biliary stones and inflammation.

Primary hyperoxaluria type 3 (PH3) is a rare monogenic nephrolithiasis caused by HOGA1 gene mutations. With the advancement of technology of genetic testing, the mutation site of PH3 patients can be clearly located, and the characteristics of genotype, phenotype, genotype-phenotype correlations are also gradually recognized. With the development of gene therapy, novel gene editing techniques and RNA interference treatments offer hope for the future of PH3 treatment. In this paper, the characteristics of genotype and phenotype, genotype-phenotype correlations of PH3 will be summarized and its future treatment will be prospected.

Pyran- and furanocoumarins are key representatives of tetrahydropyrans and tetrahydrofurans, respectively, exhibiting diverse physiological and medical bioactivities. However, the biosynthetic mechanisms for their core structures remain poorly understood. Here we combined multiomics analyses of biosynthetic enzymes in Peucedanum praeruptorum and in vitro functional verification and identified two types of key enzymes critical for pyran and furan ring biosynthesis in plants. These included three distinct P. praeruptorum prenyltransferases (PpPT1-3) responsible for the prenylation of the simple coumarin skeleton 7 into linear or angular precursors, and two novel CYP450 cyclases (PpDC and PpOC) crucial for the cyclization of the linear/angular precursors into either tetrahydropyran or tetrahydrofuran scaffolds. Biochemical analyses of cyclases indicated that acid/base-assisted epoxide ring opening contributed to the enzyme-catalyzed tetrahydropyran and tetrahydrofuran ring refactoring. The possible acid/base-assisted catalytic mechanisms of the identified cyclases were theoretically investigated and assessed using site-specific mutagenesis. We identified two possible acidic amino acids Glu303 in PpDC and Asp301 in PpOC as vital in the catalytic process. This study provides new enzymatic tools in the epoxide formation/epoxide-opening mediated cascade reaction and exemplifies how plants become chemically diverse in terms of enzyme function and catalytic process.
