AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

Objective:To establish a quality and safety evaluation index system for the daytime chemotherapy in the Day Medical Management Quality Control Center of Fujian Province, providing references for objectively evaluating the quality of day chemotherapy.Methods:From December 2023 to August 2024, this study screened the initial indexes of the quality and safety evaluation index system for daytime chemotherapy through literature search and expert discussions. An index system and its weights were determined by using two rounds of Delphi method and precedence chart method. The quality of daytime chemotherapy services in 8 hospitals was evaluated by using a thousand point scale checklist based on this index system.Results:The expert motivation of both rounds of Delphi method was 100%, and the expert authority coefficient was 0.92. The quality and safety evaluation index system for daytime chemotherapy included 3 first-level indicators, 13 second-level indicators, and 54 third-level indicators; Among them, the weights of the first-level indicator included structure quality, process quality, and result quality were 0.334, 0.556, and 0.110, respectively. The quality and safety scores of daytime chemotherapy in 8 hospitals ranged from 812 to 980 points, with an average of 933 points.Conclusions:The quality and safety evaluation index system for daytime chemotherapy could objectively and comprehensively evaluate the quality and safety of hospital daytime chemotherapy.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective To investigate the effects of ultrasound-guided thoracic paravertebral nerve block on postoperative analgesia and risk events in patients with scapular fracture caused by military training.Methods Seventy patients with scapular fracture who were admitted to the Marine Corps Hospital from January 2022 to December 2022 were randomly divided into control group and observation group.All fractures were caused by military training and treated with internal fixation under general anesthesia.The patients in the observation group additionally received ultrasound-guided thoracic paravertebral nerve block.The hemodynamics before and after skin incision,postoperative pain,and adverse events were compared between the two groups.Results The hemodynamic indexes did not significantly change at 5 min after skin incision(P>0.05).Heart rate(HR)and mean arterial pressure(MAP)in the observation group were lower than those in the control group at 5 min after skin incision(P<0.05).The visual analogue scale(VAS)scores at rest and in active state in the observation group were lower than those in the control group at 6 h and 12 h after surgery(P<0.05).The incidence of postoperative adverse events in the observation group was 5.71%,which was lower than that in the control group(25.71%,P<0.05).Conclusion Ultrasound-guided thoracic paravertebral nerve block can reduce the hemodynamic response caused by skin incision,postoperative pain,and the incidence of postoperative adverse events such as nausea and vomiting in patients with scapular fracture caused by military training.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

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.

Objective To investigate the effects of comprehensive nutrition management on glycolipid metabolism and pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods A total of 121 pregnant women with GDM at 24-28 weeks gestation who were registered in the obstetrics department of 6 sub-central hospi-tals in China from May 2021 to July 2021 were included in this study and were randomly divided into intervention group(n=74)and control group(n=47).The intervention group received intensive comprehensive nutrition man-agement,including at least 6 outpatient interventions,individualized nutrition management and a half-day standard-ized outpatient education on gestational diabetes mellitus,continuous dynamic blood glucose monitoring and micro-blood glucose monitoring,and routine check of glycated albumin and urine every 4 weeks.Body weight,body com-position and diet and exercise implementation procedures and fetal development as well as complications were recor-ded.The control group received conventional nutritional guidance.The two groups were compared for difference in blood glucose related indicators at 37 weeks of gestation,weight gain before delivery,some lipid metabolism indica-tors,pregnancy outcomes,and oral glucose tolerance test(OGTT)at 42 days postpartum.Results Compared with the control group,the level of prenatal fasting blood glucose(P=0.006),intravenous plasma glucose(P=0.009)and blood ketone(P = 0.044)in the intervention group was significantly reduced.There was no significant difference in weight gain and weight attainment rate between the two groups.The 2-hour postpartum OGTTs of preg-nant women in the intervention group(P=0.006)were significantly lower than those in the control group,and the incidence of preeclampsia and postpartum blood loss were lower than those in the control group but no statistical difference was found.For newborns,the incidence of macrosomia(P=0.042)and planation(P=0.048)in the in-tervention group was slightly lower than that in the control group,and the results were statistically different.Other adverse pregnancy outcomes were not statistically different between the two groups.Conclusions Intensive compre-hensive nutrition management has a positive impact on the control of the blood glucose in pregnant women and im-proves the maternal and neonatal outcomes of women with GDM.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.
