Objective To observe the clinical effects and postoperative recurrence of endoscopic natural opening in the middle nasal meatus-maxillary sinus and prelacrimal recess approach in treating antrochoanal polyp(ACP).Methods Clinical data of 64 patients with ACP from March 2019 to March 2023 were analyzed retrospectively.According to different surgical approaches,the patients were divided into control group(n=32,endoscopic natural opening in the middle nasal meatus-maxillary sinus)and study group(n=32,endoscopic prelacrimal recess approach).Clinical efficacy,surgical indicators,preoperative and postoperative Lund-Mackay nasal endoscopy scores and sinus CT scores were compared between the two groups.Complications and recurrence that occurred within 5 months after surgery were recorded.Results The total clinical effective rate in the study group was 93.75%,higher than that in the control group 75.00%,the difference was statistically significant(P<0.05).Intraoperative blood loss of the study group less than that of control group,hospital stay of the study group shorter than that of the control group,the differences were statistically significant(P<0.05).Three months after surgery,Lund-Mackay nasal endoscopy scores and Lund-Mackay CT scores of both groups decreased,and the study group was lower than those of the control group,the differences were statistically significant(P<0.05).The recurrence rate in the study group was 3.13%,lower than that in the control group 18.75%,the difference was statistically significant(P<0.05),but there was no significant difference in the total incidence of postoperative complications between the groups(P>0.05).Conclusion Endoscopic prelacrimal recess approach is effective in the treatment of ACP.It can clean up the lesions,with little intraoperative blood loss and short hospital stay.Compared with endoscopic natural opening in the middle nasal meatus-maxillary sinus,the recurrence rate after endoscopic prelacrimal recess approach is lower.

Objective·To explore the association between gene-gene interaction of glutamate pathway and anhedonia.Methods·A total of 279 patients with schizophrenia(SZ)and 236 patients with major depression disorder(MDD)recruited in the outpatient department and ward of Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 236 healthy controls(HC)recruited in the community from January 2017 to August 2020 were included in the study.General demographic data and clinical characteristics of the three groups were collected and compared.The Chinese version of Temporal Experience of Pleasure Scale(TEPS)was used to evaluate the pleasure experience ability of the three groups.Generalized multifactor dimensionality reduction(GMDR)method was used to establish the interaction model of the single nucleotide polymorphism(SNP)in glutamate pathway genes(NOS1AP,GSK3β,DAOA,DISC1 and GRIN2A).According to the interaction model,SZ and MDD patients were divided into high-risk group and low-risk group,and the differences in pleasure experience ability were compared between the two groups,so as to analyze the effect of gene-gene interaction on anhedonia.Results·There were significant differences in age and years of education among the three groups,and in age of onset and duration of illness between SZ and MDD groups(all P=0.000).There were significant differences among the three groups of participants in terms of overall pleasure experience,anticipatory pleasure experience and consummatory pleasure experience(all P=0.000);the overall pleasure experience,anticipatory pleasure experience and consummatory pleasure experience in the SZ and MDD group were lower than those in the HC group(all Pcorr=0.000),and there was marginal statistical difference in anticipatory pleasure experience between the SZ and MDD groups(Pcorr=0.051).Through GMDR modeling,it was found that the 2-loci interaction model composed of DAOA-rs3916965 and DISC1-rs821577 had a predictive effect on the overall pleasure experience ability of SZ patients(P=0.003),and the 2-loci interaction model composed of NOS1AP-rs1858232 and GRIN2A-rs1014531 had a predictive effect on the anticipatory pleasure experience ability of MDD patients(P=0.037);moreover,the overall pleasure experience ability of patients in the SZ high-risk group and anticipatory pleasure experience ability of patients in MDD high-risk groups were lower than those in their low-risk groups(t=3.443,P=0.000;t=3.471,P=0.001).Conclusion·The interaction of glutamate pathway gene polymorphisms may be involved in the occurrence of anhedonia.

Objective:To explore the clinical effects of two kinds of nasal bone reductors used for shortened and displaced overlapping external nasal fracture reduction under nasal endoscopy and the impact on ventilation function. Methods:From January 2020 to February 2022, 82 patients with shortened and displaced overlapping external nasal fractures diagnosed and treated in the Department of Otolaryngology, the Second People's Hospital of Hefei were collected as the study subjects. The patients were divided into control group（41 cases） and observation group（41 cases） by random number table method. Both groups underwent closed reduction under nasal endoscopy. The control group was treated with traditional straight nasal bone reductor, and the observation group was treated with gun-shaped hook type nasal bone reductor. The success rate of reduction, follow-up rate, clinical effect, and complications were compared between the two groups. The visual analogue scale（VAS） was used to evaluate the aesthetic effect and functional recovery. Rhinomanometry and acoustic rhinometry were used to evaluate nasal ventilation function. Results:The success rate of one-time reduction in the observation group was significantly higher than that in the control group, and the nasal reduction adaptation time was shorter than that in the control group（P<0.05）. There was no significant difference in the follow-up rate of 95.12% and 92.68% between the two groups. The success rate of one-time reduction in observation group was significantly higher than that in the control group, and the adaptation time for nasal reduction in observation group was shorter than that in the control group（P<0.05）. There was no significant difference in the follow-up rate of 95.12% and 92.68% between the two groups in six months after surgery. the total clinical effective rate in observation group was higher than that in the control group（94.87% vs 76.32%, P<0.05）. After surgery, the scores of nasal aesthetics, nasal congestion and olfactory function in both groups were significantly lower compared with the preoperative scores. All the scores in the observed group were lower than that in the control group（P<0.05）. After surgery, there were significant increases in the minimum cross-sectional area of nasal cavity, volume of nasal cavity and total nasal expiratory volume in both groups. Above indicators in observation group were significantly greater than that in control group. The nasal exhalation and inhalation resistance was significantly lower than that before operation, and the resistance in observation group was significantly lower than that in control group（P<0.05）. The total incidence of complications was lower than that in observation group（P<0.05）. Conclusion:The application of gun-shaped hook-type nasal bone reductor in patients with shortened and displaced overlapping external nasal fractures has better success rate of one-time reduction, adaptation time of nasal reduction and treatment outcome. Moreover, it has more advantages in aesthetic effect of nasal appearance, nasal ventilation function and reduction of complications.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective: To explore the prevalence of eating problems of preschool children in Hefei and its influencing factors, and to provide references for reducing the occurrence of dietary behavior problems of local children and strengthening the construction of children nutrition clinic in maternal and children health care institutions. Methods: A total of 1 873 children aged 3-6 years in urban and rural areas of Hefei were selected by random cluster sampling. Demographic and eating behavior of the child, as well as caregiver’s feeding behavior were investigated. Results: The study found that 72.77% of children had eating problems. The feeding behavior of feeders and the family environment factors had an impact on children’s eating behavior problems, and the main influencing factors of children’s eating behavior included father’s education level, family economic monthly income level, family members’ eating behavior problems, number of children living together and whether they are the only-child in the family(P<0.05). Conclusion The prevalence of eating problems of children aged 3-6 years in Hefei is higher. Family demographic, caregiver feeding behavior, as well as the environment of the family affect children’s eating behavior. Child nutrition clinics, promotion of caregivers’feeding practices could be effective interventions aiming to address eating problems among preschool children.

Objective To explore the relationship between the serum neuropeptide Y (NPY) levels and the pathogenesis,therapeutic intervention of schizophrenia. Methods One hundard twenty-five patients with schizophrenia (case group) with no medication for at least 4-week and 136 healthy controls (control group) were evaluated by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Positive and Negative Syndrome Scala (PANSS). Simultaneously blood tests were performed to detect serum NPY levels. In the case group, PANSS was evaluated and blood collected again after 4 weeks of treatment with olanzapine. Result At the baseline,the serum NPY concentration was significantly lower in the case group than in control group (t=-5.79, P<0.01). The scores of RBANS and its factors were significantly lower in the case group than in control group (all P<0.01). The concentration was positively correlated with the score of the attention factor for RBANS scale (r=0.20, P=0.04). After treatment with olanzapine for 4 weeks,the serum NPY level in the case group was significantly increased (t=-2.23,P=0.03).The scores of PANSS total scale and subscale were significantly decreased(all P<0.01).There was no significant correlation between alterations of the serum level of NPY and PANSS total or subscale scores from baseline to 4-week (all P>0.05). Conclusion The present study has revealed a significant decrease in serum NPY levels in patients with schizophrenia which can be attenuated by treatment of Olanzapine.The action of Olanzapine may be related to the mechanism of action of Olanzapine.However,there is no correlation between alterations of the serum level of NPY and the improvement in the patientˊs clinical symptoms.

Objective: To investigate the clinical efficacy of preoperative-, postoperative-radiotherapy and surgery for preserving laryngeal function in patient over 70 years of age with medial wall pyriform sinus cancer. Methods: Clinical data of 48 patients over 70 years of age with medial wall pyriform sinus cancer who received surgical treatment from January 2001 to December 2010 were retrospectively analyzed. Among them, 21 cases were given preoperative radiotherapy and surgery (R+ S). The radiation therapy dose was 45 Gy. And 14 cases′ larynx is preserved. In addition, 27 cases were given postoperative radiotherapy and surgery (S+ R). The radiation therapy dose was 65 Gy. And 10 cases had preserved laryngeal function. Survival rates were analyzed by the Kaplan-Meier method. Chi-square test was used to compare complications between two groups. Results: The larynx preservation rate in R+ S group [66.7% (14/21)] was significantly higher than that in S+ R group [37.0% (10/27), P<0.05]. The complication rate and decannulation rate in R+ S group were 42.9% (9/21) and 64.3% (9/14), respectively, showing no difference compared with those in S+ R group [37.0% (10/27) and 50.0% (5/10), respectively] (all P>0.05). The complication rates of patients with and without larynx preservation were 41.7% (10/24) and 37.5% (9/24), respectively, showing no difference between two groups (P>0.05). The overall 3-years and 5-years survival rates for all patients were 54.2% (26/48) and 35.4% (17/48), respectively. There was no significant difference in survival rates between R+ S [38.1% (8/21)] group and S+ R group [33.3% (9/27), P>0.05)]. In the R+ S group, the survival rates in patients with and without larynx preservation were 40.0% (4/10) and 29.4% (5/17), respectively, showing no significant difference between two groups (P>0.05). Conclusions It is secure and effective to choose the operation with laryngeal preservation for patient over 70 years of age with medial wall pyriform sinus cancer based on their physical conditions and the tumor extension. The preoperative- and postoperative-radiotherapy have the similar effect. Preoperative radiotherapy and surgery increases the laryngeal preservation rate.

Objective To investigate the implementation effect of the situation-background-assessment-recommendation (SBAR) communication mode in hospital surgical teams from the elaborate perspective. Methods Since 2015, the surgical teams of Wuxi No.2 People's Hospital, Affiliated to Nanjing Medical University combined the elaborate management with the SBAR communication mode. The elaborate SBAR report mode was established in the surgeries. Security check reports were carried out in the surgeries. The quality of the nurses' shifting of duty, the incidence of adverse events and the satisfaction of patients after the implementation of the mode were compared to before the implementation.Results The time of the nurses' shifting of duty was shortened from (13.1±4.5)min to(7.4±2.1)min significantly (t=10.737,P<0.01). The incidence of adverse events due to poor communication decreased from 50% to 13.33% significantly (χ2=4.950,P<0.05). The patients' satisfaction on the work of operating rooms increased from 84.44% to 95.74% significantly (χ2=6.652, P<0.05).Conclusions The implementation of the hospital surgical team SBAR communication mode in operating rooms from the elaborate perspective effectively upgrades the meaning of specialist care, optimizes the service procedure and reduces the incidence of adverse events due to poor communication, which guarantees the safety of surgical patients.
