Curettage is the main treatment method for oral maxillofacial cystic lesions,but simple curettage may easily damage surrounding structures such as adjacent teeth and nerves,leading to incomplete removal of the cyst and large jaw defects.The curettage assisted by endoscopy can provide a good surgical field for the surgeons,can clearly identify the important anatomical structure during the operation and can remove the cyst wall tissue as much as possible,thereby reducing the damage and reducing the recurrence rate of the lesion.This article combines the characteristics of maxillofacial surgery with clinical treatment experience,summarizes relevant literature from both domestic and international sources,and engages in discussions with experts in order to provide reference for the clinical treatment of jaw cystic lesions with endo-scope assisted curettage.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

To clarify the genetic diversity and structure of the nucleus population of F1-generation Litopenaeus vannamei, this study utilized 15 pairs of highly polymorphic microsatellite primers to analyze the simple sequence repeat (SSR) markers and genetic diversity in 15 full-sib families of L. vannamei. A total of 112 alleles (N_a) and 60.453 effective alleles (N_e) were identified among the selected 15 SSR loci, with the average polymorphic information content (PIC) of 0.648. The average N_e, observed heterozygosity (H_o), and expected heterozygosity (H_e) in the 15 F1 families varied from 1.925 to 2.626, 0.425 to 0.783, and 0.403 to 0.572, respectively. The 15 full-sib families were primarily clustered into three categories in the phylogenetic analysis, with the genetic distance between families ranging from 0.252 to 0.574. Additionally, the genetic differentiation coefficient (F_st) among the families varied from 0.112 to 0.278, indicating substantial genetic differentiation. Overall, this study suggested that the genetic diversity of the 15 full-sib families was moderate, providing valuable genetic insights for the subsequent breeding initiatives aimed at enhancing the tolerance of L. vannamei to high levels of soybean meal.

Surgery is currently the most appropriate treatment for early-stage non-small cell lung cancer (NSCLC). Increasing unilateral or bilateral multiple primary lung cancer being found, segmentectomy has attracted wide attention for its unique advantages in the treatment for such tumors. Ground glass opacity dominant early-stage NSCLC is associated with a good prognosis and can be cured by segmentectomy, however, the treatment of solid-dominant NSCLC remains controversial owing to the invasive nature. With the in-depth study on the lymph node metastasis pathway, radiological characteristics and molecular biology of NSCLC, a large part of solid nodules with certain characteristics can also be cured by segmentectomy. This paper reviews the research status and progress about the indication of segmentectomy.

Objective: To explore the special situation in subxiphoid uniportal VATS surgery and summarize the treatment strategies. Methods: In September 2014, the subxiphoid uniportal VATS surgery was carried out. Up to now, our research team has completed more than 300 subxiphoid uniportal VATS operations, especially including 242 cases of subxiphoid uniportal VATS segmentectomy and 22 cases of subxiphoid uniportal VATS mediastinal tumor resection. Some special situations were encountered during the operation, including cardiac arrest, pericardial tamponade, innominate venous injury, severe arrhythmia, difficulty in positioning the lung segment, and difficulty in positioning the small nodule et al. Results: Some patients changed the surgical procedure during surgery due to intraoperative emergencies such as severe arrhythmia, heart problems, intraoperative bleeding. Postoperative complications mainly included thoracotomy and hemostasis, continuous air leak after operation, pulmonary hematoma, arrhythmia, and no perioperative death. Conclusion Under the subxiphoid uniportal VATS surgery is an important manifestation of the minimally invasive technique of the chest. It is safe and feasible to select suitable cases, master the thoracoscopic technique and special surgical techniques. Special situations during subxiphoid uniportal VATS surgery should be known.

The present study reported the case of a patient with degenerative lumbar scoliosis who suffered from postoperative hemorrhage due to lumbar artery injury in corrective osteotomy. The patient presented with decline of blood pressure, extremely low hemoglobin, even after blood transfusion and fluid infusion. Digital subtraction angiography showed lumbar artery injury. Successful control of bleeding and gradually stable vital signs were observed after vascular embolisation. Severe and complex spinal deformity, severe osteophytes in the anterior edge of vertebral body, hypertension, and angiosclerosis were the risk factors of large vascular injuries in spinal osteotomy. Lumbar artery injury should be highly suspected when unknown and progressively aggravating abdominal or back pain, abdominal distention, neurological symptoms of lower limbs, decline of blood pressure, increase of heart rate, decrease of hemoglobin level, continuously bloody drainage or incision bleeding occurred. Vascular embolisation was effective and safe in the management of iatrogenic lumbar artery injury.
