Objective:To investigate the clinical effect of jujube core-shaped tissue resection technique in the treatment of alar reduction.Methods:A retrospective analysis was performed for the clinical data of patients who underwent alar reduction from February 2019 to June 2022. A spindle-shaped incision line was designed along the outer edge of the base of the nasal lobule, with a width of 4-5 mm and a length of 8-12 mm. The incision line was 1-2 mm away from the alar groove, and the inner side of the design line was extended to the inside of the nasal vestibule. After the incision was made, the subcutaneous tissue was undermining dissected with curved sharp scissors, and the shape of the extended excision tissue was similar to that of jujube core. After reduction, the incision was closed with vertical mattress suture. The surgical effect and complications were followed up after surgery, and an independent attending plastic surgeon evaluated the outcome and scarring based on photos before and at the last postoperative follow-up using the global aesthetic improvement scale (GAIS) and the Vancouver scar scale (VSS). GAIS is graded as 1, 2, 3, 4, and 5 points, and the lower the score, the better the improvement(≤3 points as effective improvement). VSS includes four parameters: color (0-3 points), thickness (0-4 points), vascular distribution (0-3 points), and softness (0-5 points). The higher the score, the more significant the scar is.Results:A total of 20 patients were enrolled, including 6 males and 14 females, aged 20 to 33 years, with an average age of 24.9 years. Before the operation, there were different degrees of alar flare and alar hypertrophy. After surgery, 13 patients had mild swelling, ecchymosis, which resolved after 3 days. There were no major complications as infection, incision dehiscence, and delayed healing. After 3 to 16 months of postoperative follow-up, 2 patients gradually developed cartilage deformation and affected the appearance of the nostrils 6 to 9 months after surgery due to the combination of rib-based rhinoplasty, and the satisfactory results were obtained after revision surgery. The symmetry of the nostrils was significantly improved. The GAIS score of 20 patients was (1.20±0.41) points, of which, 16 patients were rated as 1 point and 4 patients were rated as 2 points, all of which met the improvement criteria, and the VSS score was (1.45±0.60) points, in which the average score for color, thickness, vasculature and compliance are 0.60, 0.05, 0.55 and 0.30 points respectively.Conclusion:The application of jujube core-shaped tissue resection technique for alar reduction can increase the amount of tissue removal with the same incision width, which can not only fully narrow the alar effectively but also correct the hypertrophy of the alar tissue.

Abstract Biomarkers could improve the understanding of the causes of obesity and its association with chronic diseases for people. The purpose of the review is to summarize recent advances in transcriptomic, proteomic, and metabolomic phenotypic biomarkers of obesity in order to deepen the understanding of the etiology of obesity and its metabolic consequences. In the precise prevention and control of childhood obesity, different groups of biomarkers can improve the accuracy of the word "obesity" and help early detection of specific biomarkers with risk characteristics, so as to realize the transformation of childhood obesity from a one size fits all prevention and control strategy to a personalized prevention and control plan during the development of obesity.

Abstract Childhood obesity is one of the major global public health challenges and has a profound impact on the physical and mental health of children and adolescents. The article summarizes the establishment of gut microbiota in early life and the influences of early nutritional status and feeding patterns, maternal and infant microbiota transmission, delivery methods and the use of antibiotics on gut microbiota and childhood obesity. The paper focuses on the possibility of using the structural characteristics of gut microbiota (gene richness and evenness, relative abundance ratio and key indicator bacteria) as potential interventional targets and predictors of intervention effects in childhood obesity, and introduces the application of probiotics and other biological agents, as well as fecal microbiota transfer for the childhood obesity intervention, and briefly describes the latest progress in the mechanism of gut microbiota and childhood obesity, so as to provide the reference for the precise prevention and control of childhood obesity.

Objective To evaluate the effect of endoscopic laryngeal mask on perioperative airway management and postoperative recovery in patients undergoing gastric endoscopic submucosal dissection(ESD).Methods Ninety patients,aged 18-64 years,BMI 18-25 kg/m2,ASA physical statusⅠorⅡ,who underwent elective gastric ESD were randomly divided into two groups:the endoscopic laryngeal mask group(group E)and the endotracheal tube group(group C),45 patients in each group.After induction of general anesthesia,group E received endoscopic laryngeal mask airway ventilation,and the endoscope was inserted through the endoscopic channel of the laryngeal mask,group C received tracheal intubation,and the endoscopy was inserted through the mouth.The successful time and one-time success rate of intubation,and the insertion time and withdrawal rate of endoscopy were recorded.The operative time,extubation time and PACU residence time were recorded.HR,MAP were recorded when the patient entered the room(T0),at the time of intubating(T1),inserting gastroscopy(T2),exiting gastroscopy(T3),extubation(T4),and leaving PACU(T5).The average airway pressure and peak airway pressure at T1-T3 were recorded.The airway sealing pressure and endoscopic view grading system(EVGS)grading of group E were recorded before and after changing the position,and at the end of surgery.The adverse reactions and the satisfaction of anesthesiologists and gastroenterologists were recorded.Results Compared with T0,HR and MAP were significantly increased at T1 and T4 between the two groups(P＜0.05).Compared with group C,the suc-cessful time of intubation,the extubation time,and PACU residence time were significantly shortened,HR and MAP were significantly decreased at T1 and T4,the incidence of choking cough during extubation,post-operative pharyngeal pain,and hoarseness were significantly decreased(P＜0.05).There were no signifi-cant differences in the one-time success rate of intubation,the insertion time and withdrawal rate of endosco-py between the two groups.Endoscopic laryngeal mask showed good sealing and alignment in group E.Conclusion Endoscopic laryngeal mask could shorten the success time of establishment of artificial airway in patients with gastric ESD,without interfering with digestive endoscopy operations,shorten extubation time and PACU retention time,maintain intraoperative hemodynamic stability,and reduce adverse reactions.

Objective:To analyze the efficacy of endoscopic laryngeal mask in obese patients undergoing upper gastrointestinal endoscopic mucosal resection (EMR).Methods:Adopting a prospective research approach, 90 obese patients who underwent upper gastrointestinal EMR from July 2020 to May 2022 in Nanjing First Hospital, Nanjing Medical University were selected. The patients were divided into endoscopic laryngeal mask group (using general anesthesia with endoscopic laryngeal mask ventilation) and nasal catheter group (using conventional non intubated intravenous anesthesia) by random digits table method with 45 cases in each. The EMR time; minimum pulse oxygen saturation (SpO 2) during perioperative period; changes of SpO 2, mean arterial pressure (MAP) and heart rate during perioperative period; palinesthesia time; postoperative postanesthesia care unit (PACU) residence time; adverse reactions; satisfaction levels of doctor and patient satisfaction were recorded. Results:There were no statistical difference in EMR time and postoperative PACU residence time between two groups ( P>0.05). There were no statistical difference in minimum SpO 2 preoperative and anesthesia induction period between two groups ( P>0.05); the minimum SpO 2 EMR period in endoscopic laryngeal mask group was significantly higher than those in nasal catheter group (0.990 ± 0.010 vs. 0.951 ± 0.037), and there was statistical difference ( P<0.01). There were no statistical difference in heart rate and MAP during perioperative period between two groups ( P>0.05). There were no statistical difference in SpO 2 entering the operating room and leaving the PACU between two groups ( P>0.05), SpO 2 immediately after endoscopic insertion and at the end of surgery in endoscopic laryngeal mask group was significantly higher than that in nasal catheter group (0.989 ± 0.009 vs. 0.976 ± 0.011 and 0.987 ± 0.010 vs. 0.981 ± 0.009), and there was statistical difference ( P<0.01). The palinesthesia time in endoscopic laryngeal mask group was significantly longer than that in nasal catheter group: (6.7 ± 1.1) min vs. (4.6 ± 1.2) min, and there was statistical difference ( P<0.01). Both groups did not experience aspiration, hoarseness or airway spasm. There were no statistical difference in the incidences of pharyngalgia, bradycardia, hypotension, abdominal pain and bloating, postoperative nausea and vomiting between two groups ( P>0.05). The incidence of bucking and body movement in endoscopic laryngeal mask group was significantly lower than that in nasal catheter group: 2.2% (1/45) vs. 24.4% (11/45), and there was statistical difference ( P<0.01). There were no statistical difference in the satisfaction level of patient between two groups ( P>0.05); the satisfaction levels of anesthesiologists and endoscopists in endoscopic laryngeal mask group were significantly higher than those in nasal catheter group: 95.6% (43/45) vs. 66.7% (30/45) and 88.9% (40/45) vs. 71.1% (32/45), and there were statistical differences ( P<0.01 or <0.05). Conclusions:The application of endoscopic laryngeal mask in upper gastrointestinal EMR in obese patients can effectively improve the hypoxia caused by insufficient ventilation. At the same time, it will not cause drastic fluctuations in hemodynamics, and it does not increase the incidence of throat discomfort, but it slightly extends the awakening time.

ObjectiveTo systematically review the effects of mind-body exercise on sleep quality, and to sort out the influencing factors of mind-body exercise intervention program. MethodsLiteratures about the effects of mind-body exercise on sleep were searched in PubMed, Web of Science, Science Direct, Cochrane Library, CNKI, VIP and Wanfang data from establishment to June 1, 2022. The author, country, publication time, study object, study method, intervention process, measurement tool and outcome index were extracted from the selected literature. The Physiotherapy Evidence Database (PEDro) scale was used to evaluate the methodological quality. ResultsA total of 14 English literatures were included, all of which were randomized controlled trails, and the overall research quality was good. Mind-body exercise methods included Taijiquan, Qigong and Baduanjin. Most of the subjects were old and sick people. Physical exercise intervention with a duration of ten to twelve weeks, a single time of 60 minutes and at least two to three times a week could improve sleep quality to the greatest extent. The health status of the participants was an important factor affecting the effect of the intervention. ConclusionMind-body exercise can improve sleep quality, relieve anxiety and depression, and promote mental health.

Objective:To investigate the clinical application of a cartilage graft fixation method in the context of rib-based rhinoplasty.Methods:The clinical data of patients who underwent costal cartilage based rhinoplasty in the Center of Rhinoplasty and Nasal Reconstruction, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2020 to January 2022 were retrospectively analyzed. A 20 ml syringe needle was used to drill several micropores about 1 mm in diameter on the surface of the cartilage grafts prior to its placement. "septal extension grafts with micropores" were prepared, and the preparation of the remaining grafts was conventional.Results:A total of 30 female patients aged 21-45 years, with an average age of 36 years underwent primary or repaired autogenous costal cartilage rhinoplasty without severe damage to the nasal septum cartilage (at least retention of L-shaped scaffolds larger than 10 mm) were enrolled. All operations were successful, the cartilage scaffold was stable and durable. There were no serious complications such as infection, septal hematoma and cartilage exposure. Postoperative patients were followed up for a duration of 6-24 months. Two out of 30 patients were not satisfied with the postoperative appearance. During the revision surgery, the septal perichondrium was separated, mucosal tissue had grown into the bilateral holes which further verified of the feasibility of drilling. The other patients were satisfactied with the results.Conclusion:Nasal septum extension graft based on drilling technique is beneficial to maintain the long-term stability of cartilage scaffold after comprehensive costal cartilage nasal surgery, which justifies its application in comprehensive nasal plastic surgery.

ObjectiveTo explore the relationship between mental health and sleep quality of high-level shooting athletes and its significance to psychological rehabilitation. MethodsIn March, 2021, 21 high-level shooting athletes were investigated using Pittsburgh Sleep Quality Index (PSQI) and Profile of Mood State (POMS). They were divided into normal sleep group (n = 9) and sleep disorder group (n = 12). The psychological state of athletes with different sleep quality was calculated and the correlation was analyzed. ResultsThe scores of tension, anger, fatigue, and total of motional disturb (TMD) in POMS were higher in the sleep disorder group than in the normal sleep group (t > 2.18, P <0.05). The total of PSQI postively correlated with tension, anger, fatigue, depression, panic, and TMD of POMS (r > 0.454, P < 0.05). After step regression, fatigue was the main variable related to PSQI (P = 0.001). ConclusionThe sleep quality of high-level shooting athletes is affected by mental state, and the mental fatigue is the most important factor. The follow-up psychological rehabilitation professionals should pay more attention to the negative emotions and psychological fatigue of shooting event athletes.
