Objective:To explore potential risk factors for central lymph node metastasis (CLNM) in papillary thyroid microcarcinoma (PTMC).Methods:The clinicopathological data of 304 PTMC patients admitted to Baotou Cancer Hospital from Oct 2021 to Mar 2023 were retrospectively analyzed. The risk factors of CLNM were analyzed using unifactorial and multifactorial regression.Results:The rate of central regional lymph node metastasis in 304 patients with PTMC was 46.7% (142/304). Univariate analysis showed that male, age <45 years, maximum cancerous lesion diameter ≥5 mm, total cancerous lesion diameter ≥9.5 mm, anterior-posterior lesion diameter ≥5 mm, anterior-posterior lesion diameter ratio of cancerous lesions ≥0.48, breaching of thyroid capsule, number of lymph nodes on the side of cancerous lesions ≥5, and antithyroid peroxidase antibody ≤34 IU/ml were associated with CLNM (all P<0.05); Logistic multivariate regression analysis showed that. male, age <45 years, total diameter of cancer foci ≥9.5 mm ( OR=2.052, 95% CI: 1.176-3.581, P=0.011), anteroposterior diameter ratio of cancer foci ≥0.48 ( OR=2.076, 95% CI: 1.161-3.711, P=0.014), number of lymph nodes on the side of cancer foci ≥5, and anti-thyroid peroxidase antibody ≤34 IU/ml were independent risk factors for CLNM. Conclusion:Male, age ,total diameter of cancer foci, anterior-posterior diameter ratio of cancer foci, number of lymph nodes on the side of cancer foci, and anti-thyroid peroxidase antibody level are all independent risk factors for CLNM in patients with PTMC.

Gene therapy, harnessing the power of CRISPR-Cas9 and/or DNAzyme systems, stands as a pivotal approach in cancer therapy, enabling the meticulous manipulation of genes pivotal to tumorigenesis and immunity. However, the pursuit of precise gene therapy encounters formidable hurdles. Herein, a near-infrared upconversion theranostic nanomachine is devised and tailors for CRISPR-Cas9/DNAzyme systems mediate precise gene therapy. An ingenious logic DNAzyme system consists of Chain 1 (C1)/Chain 2 (C2) and endogenous lncRNA is designed. We employ manganese modified upconversion nanoparticles for carrying ultraviolet-responsive C1-PC linker-C2 (C2P) chain and Cas9 ribonucleoprotein (RNP), with outermost coats with hyaluronic acid. Upon reaching tumor microenvironment (TME), the released Mn2+ ions orchestrate a trifecta: facilitating endosomal escape, activating cGAS-STING signaling, and enabling T1-magnetic resonance imaging. Under near-infrared irradiation, Cas9 RNP/C2P complex dissociates, releasing Cas9 RNP into the nucleus to perform gene editing of Ptpn2, while C1/C2 chains self-assemble with endogenous lncRNA to form a functional DNAzyme system, targeting PD-L1 mRNA for gene silencing. This strategy remodels the TME by activating cGAS-STING signaling and dual immune checkpoints blockade, thus realizing tumor elimination. Our theranostic nanomachine armed with the CRISPR-Cas9/DNAzyme logic systems, represents a resourceful and promising strategy for advancing cancer systemic immunotherapy and precise gene therapy.

Objective:To explore the bidirectional causal relationship between genetically predicted oral diseases and inflammatory bowel disease (IBD) by Mendelian randomization (MR) and meta analysis.Methods:Genetic datas of 4 oral diseases, including periodontitis, lichen planus, oral ulcer, and dental caries were extracted from the Integrative Epidemiology Unit (IEU) open genome-wide association study project (IEU open GWAS), and genetic datas related to IBD, ulcerative colitis (UC), and Crohn′s disease (CD) were extracted from 3 independent databases, including the meta-analysis of de Lange et al, the FinnGen database, and the International Inflammatory Bowel Disease Genetics Consortium (IIBDGC). Single nucleotide polymorphism (SNP) identified as instrumental variable (IV) for " exposure-outcome" relationship was screened by setting the association strength and eliminating linkage disequilibrium, and confounder SNP and palindromic SNP were removed at each database level. Weak IV bias was excluded according to the F-value. Inverse variance weighted (IVW) method was used as the main analysis method, and Cochran′s Q test was used to analyze the heterogeneity of a single database, and random effect or fixed effect model was selected for MR analysis according to the presence or absence of heterogeneity. The MR-Egger test and Mendelian randomization-pleiotropy residual sum and outlier(MR-PRESSO) test were used to remove outliers and evaluate horizontal pleipotency across multiple databases, and then meta-analysis was performed to summarize the effect value of multiple databases. The effect of individuol SNP on the outcome was determined by a sensitivity test using the leave-one-out method. Results:The results of the MR analysis indicated that genetically predicted lichen planus had a significant effect on IBD ( OR=1.069, 95% confidence interval (95% CI) 1.043 to 1.097, Z=5.25, P<0.001), CD ( OR=1.077, 95% CI 1.018 to 1.139, Z=2.56, P=0.010) and UC ( OR=1.075, 95% CI 1.040 to 1.111, Z=4.31, P<0.001). The reverse MR analysis revealed that IBD was associated with an increased risk of periodontitis ( OR=1.051, 95% CI 1.020 to 1.083, Z=3.25, P=0.001), lichen planus ( OR=1.166, 95% CI 1.011 to 1.344, Z=2.11, P=0.035), and oral ulcer ( OR=1.003, 95% CI 1.001 to 1.004, Z=4.28, P<0.001). There was a causal association between UC and periodontitis ( OR=1.043, 95% CI 1.009 to 1.077, Z=2.51, P=0.012). CD was significantly correlated with an increased risk of lichen planus ( OR=1.088, 95% CI 1.038 to 1.141, Z=3.48, P<0.001). Conclusions:Lichen planus may be a risk factor of the progression of IBD, and IBD may be associated with increased risk of multiple oral diseases. There may be a potential bidirectional causal relationship between oral diseases and IBD.

Objective:To explore the effect and safety of local spraying tranexamic acid after thyroidectomy.Methods:Randomized double-blind placebo-controlled study method was used. Sixty-four patients underwent scheduled thyroidectomy from December 2022 to August 2023 in Baotou Cancer Hospital were selected. The patients were divided into tranexamic acid group and control group by random digits table method with 32 cases each. Before closing the wound during surgery, 16 ml of tranexamic acid injection with concentration of 25 mg/ml was used to wash the wound and 1 ml of tranexamic acid injection (tranexamic acid 100 mg) used to locally spray in tranexamic acid group; 16 ml of the sterile water for injection was used to wash the wound and 1 ml of sterile water for injection was used locally spray in control group, and then the drainage tube was clipped for 20 min. The neck drainage volume on the first to fourth day after surgery and complication were recorded; the C-reactive protein level before and after surgery was detected.Results:Two patients in each group withdrew from the study midway. The drainage volume on the first, second and third day and total drainage volume in tranexamic acid group were significantly lower than those in control group: (29.10 ± 8.04) ml vs. (38.50 ± 8.67) ml, (18.00 ± 7.33) ml vs. (27.20 ± 10.66) ml, (10.70 ± 5.75) ml vs. (14.60 ± 6.83) ml and (69.20 ± 24.48) ml vs. (96.70 ± 31.90) ml, and there was statistical difference ( P<0.01); there was no statistical difference in the drainage volume on the fourth day after surgery between two groups ( P>0.05). There was no statistical difference in C-reactive protein before and after surgery between two groups ( P>0.05). There was 1 case of fever (body temperature 37.5 ℃) in the control group, and there were no complications such as intermuscular thrombosis, venous thrombosis, incision infection and delayed wound healing in both groups. Conclusions:Local application of tranexamic acid after thyroidectomy can reduce postoperative drainage volume and does not increase the risk of thrombosis, infection and delayed healing.

Objective :
To examine the causal relationship between ulcerative colitis (UC) and pancreatitis, to provide basis for early screening of pancreatitis among UC patients.
Methods:
Genomic data of UC were obtained from 47 745 European individuals pooled by the International Inflammatory Bowel Disease Genetics Consortium, including 156 116 single nucleotide polymorphism (SNP), and genomic data of pancreatitis were obtained from 198 166 European individuals pooled from FinnGen, including 16 380 428 SNPs. Mendelian randomization (MR) analysis was performed using the inverse variance weighted (IVW) method with 72 UC-associated SNPs as instrumental variables and pancreatitis as the study outcome. The heterogeneity was assessed using Cochran Q test, the horizontal pleiotropy was assessed using MR-Egger regression, MR-PRESSO was performed with the exclusion of outliers, and effect of individual SNP on the results was tested with the leave-one-out method.
Results:
MR analysis results showed that patients with genetically predicted UC had an increased risk of pancreatitis relative to those without UC (OR=1.076, 95%CI: 1.019-1.136, P<0.05). Cochran Q test showed no heterogeneity (P>0.05), and MR-Egger regression did not reveal horizontal pleiotropy of instrumental variables (P>0.05). The MR analysis results were robust after removing SNP one by one.
Conclusions
Genetically predicted UC is associated with an increased risk of pancreatitis. The screening for pancreatitis risk should be enhanced in patients with UC.
