Objective To explore the level of energy balance related protein antibody,adropin,and its correlation with collateral circulation status in elderly patients with AMI.Methods A total of 193 elderly AMI patients admitted to our department from February 2022 to February 2024 were enrolled,and based on their collateral circulation status,they were divided into a good circulation group(121 cases)and a poor circulation group(72 cases).The level of adropin was determined.Multivariate logistic regression analysis was employed to determine the influencing factors of poor collateral circulation in elderly AMI patients.Results The poor circulation group had significantly larger proportion of hypertension,higher fasting blood glucose(FBG),and larger red blood cell distribution width(RDW),but lower adropin level and mean platelet volume(MPV)when com-pared with the good circulation group(P＜0.05,P＜0.01).Multivariate logistic regression analy-sis showed that adropin,FBG,RDW,MPV,and hypertension were all influencing factors for poor collateral circulation in elderly AMI patients(P＜0.05,P＜0.01).The AUC value of adropin,FBG,RDW,MPV,and hypertension was 0.810,0.762,0.761,0.715 and 0.563,respectively in pre-dicting poor collateral circulation.Among them,adropin level had the highest predictive value(P＜0.01).Conclusion The decrease in adropin level in elderly AMI patients is closely associated with poor collateral circulation,and it is a predictive factor for collateral circulation.

Objective:To share our experience of single-port transoral Da Vinci robotic surgery for laryngeal and pharyngeal benign tumors.Methods:Three patients aged over 18 years and diagnosed respectively with epiglottic cyst, aryepiglottic fold cyst and thyroglossal duct cyst at tongue base were included who received operations in Hainan Hospital of Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine (Boao Research Hospital of Hainan) between August 1, 2023 and April 10, 2024. There were 1 male and 2 females, with an average age of 59 years old. The clinical diagnosis of these 3 patients was respectively epiglottic cyst, aryepiglottic fold cyst and thyroglossal duct cyst at tongue base. Intraoperative conversion rate, blood loss, operation time, hospital stay, pain score and swallowing function score were analyzed.Results:All three patients successfully underwent the operations with the single-port Da Vinci robotic system. The clean-contaminated resection rate of the tumors was 100%. The conversion rate was nil. The blood loss was 0-7 ml. The operation time was 5-30 minutes. There were no adverse events such as loosening of teeth and soft tissue abrasions of pharyngeal side wall. The rate of oral feeding within 24 hours after surgery was 100%. No postoperative coughing, bleeding, or dyspnea occurred. The average length of hospital stay was 3.7 days. The VAS score decreased 3 days after surgery compared to 1 day after surgery. The swallowing function recovered 1 month after surgery.Conclusion:The single-port transoral robotic surgery for laryngeal and pharyngeal benign lesions is safe and efficient, with fewer complications.

BACKGROUND:Unique advantages of 3D printing technology have opened up new ideas for the development of stomatology.OBJECTIVE:To summarize the application progress of 3D printing technology in stomatology.METHODS:The relevant articles were searched in CNKI and PubMed by computer.Classification search was performed using"3D printing,oral science"as Chinese search terms.Keyword search was conducted using"three-dimensional printing,stomatology,dentistry,prosthodontics,oral implant,orthodontics,oral and maxillofacial surgery,dental pulp disease,periodontitis"as English search terms.The literature that was not related to the theme of the article was initially excluded after reading.According to the inclusion and exclusion criteria,54 articles were finally included for review.RESULTS AND CONCLUSION:In the field of stomatology,the application scope of 3D printing technology is rapidly expanding,gradually replacing the traditional clinical diagnosis and treatment methods.Through the combination of digital technology and advanced material science,3D printing can accurately create 3D models,providing personalized solutions for the treatment of oral diseases,ensuring that doctors can carry out detailed planning and preview before surgery,and improve the safety of surgery.3D printing technology has shown significant advantages in customized denture production,personalized implantation,bracket-free invisible orthodontics,etc.Based on this technology,doctors can implement accurate design and production according to the patient's oral structure and needs,bringing patients a good treatment experience and prognosis.3D printing technology has also shown great potential in minimally invasive endodontic treatment and periodontal tissue regeneration,3D printed scaffolds and implants can provide a suitable environment for stem cells to promote the regeneration and repair of periodontal tissues,but at present,3D printing is still in the development stage of regenerative therapy,and more research and practice are needed to verify the effect and safety of its clinical application.

Objective:To investigate the influence of cytochrome P450 2A6 (CYP2A6) gene polymorphisms on liver function injury in patients with hyperthyroidism treated with methimazole.Methods:The study selected 90 patients with hyperthyroidism who were treated with methimazole in the Department of Thyroid Surgery at the First Affiliated Hospital of Zhengzhou University from Sept. 2023 to Aug. 2024 as the research subjects. Based on the occurrence of liver injury, they were divided into a liver injury group ( n=36) and a non-liver injury group (n=54). Peripheral blood DNA was extracted from the patients, and the CYP2A6 gene genotypes (rs8192725, rs8192720, and rs28399433) were detected using the polymerase chain reaction (PCR) amplification method. The association between CYP2A6 gene polymorphisms and liver injury induced by methimazole treatment in hyperthyroidism was analyzed. Results:The comparison of genotype distribution frequencies at the rs8192725 locus between the liver injury group and the non-liver injury group showed a statistically significant difference ( P<0.05). The AG and GG genotypes at the rs8192725 locus were protective factors against liver injury in patients with hyperthyroidism (AG vs. AA, OR: 0.21; 95% CI: 0.08-0.57; P<0.05; GG vs. AA, OR: 0.24; 95% CI: 0.06-0.89; P<0.05; AG+GG vs. AA, OR: 0.22; 95% CI: 0.09-0.54; P<0.05). The frequency of the G allele of rs8192725 in the liver injury group was significantly lower than that in the non-liver injury group (G vs. A, OR: 0.36; 95% CI: 0.19-0.70; P<0.05), indicating that it is a protective factor for liver injury in hyperthyroid patients receiving methimazole treatment. Conclusions:The CYP2A6 gene polymorphism at the rs8192725 locus is associated with the occurrence of liver injury in patients with hyperthyroidism treated with methimazole. The G allele may be a protective factor against liver injury in patients with hyperthyroidism, suggesting that individualized treatment plans can be developed based on the patient's genotype.

Thoracic anesthesia with spontaneous respiration represents a form of precision anesthesia meticulously customized to individual patients.Considering the more stringent requirements this anesthesia approach imposes on the regulation of respiratory function,the writing group of the"Consensus of Experts on the Management of Thoracic Anesthesia with Spontaneous Respiration"has formulated elaborate guidelines regarding indications and contraindications,preoperative evaluation,anesthesia implementation,common complications,and treatment strategies.This was accomplished by referencing relevant domestic and international literature and integrating it with actual clinical requirements.The objective is to standardize the rational application of this anesthesia method.
