OBJECTIVES: To investigate the effect of intubation with electromyographic (EMG) endotracheal tubes versus conventional wire-reinforced (CWR) tubes on the incidence of postoperative sore throat (POST) in patients undergoing thyroidectomy under general anesthesia and identify the risk factors for POST. METHODS: We retrospectively collected the clinical data from a cohort of 245 patients undergoing elective thyroid surgery under general anesthesia at the Sixth Affiliated Hospital of Sun Yat-sen University between October, 2024 and March, 2025. Patients received intubation with either EMG endotracheal tubes (n=100) or CWR tubes (n=145) during the operation, and the incidences of POST and other postoperative complications were compared between the two groups. Propensity score matching (PSM) was applied to adjust for the baseline differences, and multivariate logistic regression analysis was used to identify independent risk factors for POST. RESULTS: Comparisons of the baseline data revealed significant differences between the two groups (P<0.05). After PSM, 90 patients in EMG group and 75 in CWR group were included in the final analysis with matching baseline characteristics (P>0.05). Post-matching analysis showed that the EMG group had a shorter operative time (P=0.002) but a higher incidence of POST (P=0.001). Multivariate logistic regression identified the use of EMG tubes (OR=17.50, 95% CI: 2.25-136.03, P<0.01) as an independent risk factor for POST. CONCLUSIONS Intubation with EMG endotracheal tubes can shorten the operative time and allow recurrent laryngeal nerve monitoring during thyroidectomy under general anesthesia, but their structural design may increase the risk of POST. Clinical decisions should be made to balance nerve protection and postoperative patient comfort by selecting appropriate tube types and optimizing intubation strategies to enhance perioperative outcomes.

Objective: To explore the current status of hyperopic reserve and its related factors among non-myopia preschool and primary school students aged 5 to 12 years in Guangdong Province, so as to provide a basis for formulating intervention strategies for the pre myopia stage of children. Methods: From October to December 2023, by using stratified cluster random sampling method, a survey on hyperopic reserve among preschool children and primary school students in Guangdong were conducted. And a total of 10 567 children from the senior class of kindergarten to the sixth grade of primary school who completed autorefraction measurements with and without cycloplegia and the questionnaire survey were included in the study. The prevalence characteristics of low hyperopic reserve among non-myopia children were analyzed, and multivariable Logistic regression was used to analyze the related factors. Results: The prevalence rate of low hyperopic reserve among 8 790 non-myopia children was 62.4%. The average spherical equivalent (SE) for children aged 5 to 12 years was 0.88 (0.25, 1.25)D, decreasing from 1.13 ( 0.75 , 1.50)D in senior kindergarten to -1.00 (-2.50, 0.38)D in sixth grade, with the difference was statistically significant ( H=2 475.3, P <0.01). Multivariable Logistic regression analysis, after adjusting for confounders including gender, urban and rural, and grade, revealed that parental myopia was a risk factor for low hyperopic reserve in the preschool stage (one parent with myopia: OR=1.62, 95%CI =1.35-1.93; both parents with myopia: OR=2.05, 95%CI = 1.66 -2.55); in the lower primary school stage, parental myopia (one parent with myopia: OR=1.46, 95%CI =1.27-1.68; both parents with myopia: OR=1.58, 95%CI =1.33-1.89), frequently or always reading or using electronic screens while lying down or on one s stomach ( OR=1.43, 95%CI =1.13-1.81), and never or occasionally maintaining a viewing distance of over 3 meters when watching TV/playing video games ( OR=1.34, 95%CI =1.04-1.72) were risk factors; in the higher primary school stage, failing to take a break every hour during near work ( OR=1.79, 95%CI =1.16-2.75) was a risk factor (all P <0.05). Conclusions The emmetropization of children aged 5-12 years in Guangdong Province is accelerated, and non-myopia children generally exhibit insufficient hyperopic reserve. The contributing factors for insufficient hyperopia reserve in non-myopia children vary across different educational stages, necessitating targeted precision interventions.

Objective To analyze the use of outcome indicators and evaluation tools in randomized controlled trial(RCT)of music interventions for lung cancer-related anxiety and depression.Methods Nine databases were searched,and the literature was screened according to inclusion and exclusion criteria,followed by a summary of outcome indicators,and statistical analysis of classification and frequency of use according to the attributes of the outcome indicators.Results A total of 243 articles were retrieved,and 18 RCTs were finally included.The outcome indicators were classified into 8 indicator categories according to their functional attributes:anxiety scale(24.19%),depression scale(16.13%),quality of life scale(14.52%),sleep quality scale(9.68%),pain scale(4.84%),blood biochemical indicators(14.52%),vital signs(11.29%),and pulmonary and exercise function indicators(FEV1%,6MWD,BODE index)(4.84%).The problems are as follows:First,the overall risk of bias is high in the included RCTs.Second,the timing of measurement is variable due to inconsistency in the length of treatment.Third,the forms of music intervention are diverse.Besides,the use of other rating scales and objective indicators is low and safety indicators were neglected.Finally,the method of evaluation tools was single and some RCTs did not specify grading criteria.Conclusion The use of outcome indicators and evaluation tools in music interventions for lung cancer-related anxiety and depression has certain shortcomings,which affects the credibility of the trials.It is recommended to standardize the use of outcome indicators and establish a core set of indicators for clinical studies of music intervention for lung cancer-related anxiety and depression.

Objective:To evaluate the clinical curative effect of Huangqi Chifeng Decoction combined with modified Duhuo Jisheng Decoction on patients with ischemic stroke (IS) during recovery.Methods:Prospective cohort study. A total of 220 patients with IS during recovery who met inclusion criteria in the First People's Hospital of Dongcheng District in Beijing, were enrolled and divided into control group ( n=110) and observation group ( n=110) by random number table method between January 2015 and July 2020. The control group was given basic treatment, while observation group was given Huangqi Chifeng Decoction combined with modified Duhuo Jisheng Decoction. All were treated for 1 month. Before and after treatment, Traditional Chinese Medicine (TCM) syndromes were scored. The activities of daily living were evaluated by Barthel index. The quality of life was evaluated by stroke specific quality of life scale (SS-QOL). The severity of neurological impairment was evaluated by National Institute of Health Stroke Scale (NIHSS). The functional recovery of stroke was evaluated by modified Rankin scale (mRS). The adverse reactions during treatment were observed and recorded. Results:After treatment, scores of TCM syndromes, mRS and NIHSS in observation group were significantly lower than those in the control group ( t=21.87, 4.66, 12.06, P<0.01), while scores of Barthel index and SS-QOL were significantly higher than those in the control group ( t=14.13, 5.80, P<0.01). During treatment, there were no obvious adverse reactions in either group. Conclusion:Huangqi Chifeng Decoction combined with modified Duhuo Jisheng Decoction can improve clinical symptoms and nerve function in patients with IS during recovery, which is beneficial to improve outcomes and quality of life.

Medical microbiology experiment is faced with many problems in online teaching. This study adopts the teaching mode of online live broadcast + operation video + virtual experiment, and make up the operation gap to some extent through operation video and virtual experiment. The mode of assessment is subjective thinking question (closely following the operation process) + experiment design + literature review (focusing on the key technology or new technology of clinical assessment that cannot be carried out due to the limitation of conditions in traditional experiments, such as mass spectrometry, fluorescence quantitative PCR, and G-test), and it is helpful to understand students' mastery of teaching objectives, and the ability of comprehensive application and innovative thinking. The student questionnaire shows that most students hold a positive attitude towards the online experimental teaching mode, and the quality of students' homework shows that most students have a good learning effect.

Objective: To understand the status and associated factors of knowledge, attitude and practice (KAP) about myopia prevention and control among young children s parents in Guangzhou, so as to provide reference for family health education on myopia prevention and control. Methods: During January to February 2023, 4 584 parents of children from kindergarten and primary school (grade 1-3) were recruited. Two to three kindergartens and 2 primary schools were selected from each of the 3 urban districts and 2 suburb districts of Guangzhou by stratified cluster random sampling method. Parents of children were administered with online questionnaire survey on KAP about myopia prevention and control. Descriptive analyses and multivariate Logistic regression models were used. Results: The proportion of parents reaching standard of KAP about myopia prevention and control was 61.54%, the knowledge awareness rate was 57.30%, the positive attitude holding rate was 76.98% and the health practice formation rate was 63.31 %. Internet (70.35%) and lectures on school health education/health education materials (66.14%) were the most common ways for obtaining knowledge for parents. Multivariate Logistic regression analysis showed that urban area, higher education ( college /undergraduate or above), annual household income 50 000-90 000, 100 000-290 000, 300 000-490 000, 500 000- 590 000 , and ≥600 000 Yuan, being aware of vision status (normal/poor) of their children, one or both parents with myopia, both parents with non myopia, acquiring knowledge by multi ways(2, 3, ≥4) were associated with higher KAP about myopia prev ention and control ( OR =1.23, 1.34, 1.36, 1.25，1.49, 1.93, 2.34, 1.64, 1.66, 1.89, 3.48, 3.09, 2.42, 1.65, 2.29, 3.22, P ＜ 0.05). Conclusion Knowledge and practice about myopia prevention and control among young children s parents in Guangzhou are insufficient, yet the attitude was satisfactory. It is necessary to carry out targeted education for parents, especially those living in suburb area, with low education and income level.

Background: Red blood cell distribution width/platelet count ratio (RPR) is a reliable prognostic assessment indicator for numerous diseases. However, no studies to date have examined the relationship between RPR and the prognosis of diffuse large B-cell lymphoma (DLBCL).Therefore, this study aimed to investigate the correlation between RPR and the clinical characteristics and prognosis of patients with diffuse large B-cell lymphoma. Methods: We retrospectively studied 143 patients with newly diagnosed DLBCL and used the median value as the RPR threshold. We also investigated the correlation of pretreatment RPR level with clinical characteristics and its impact on DLBCL prognosis. Results: Using the median value as the cut-off, patients with DLBCL were divided into a low RPR group (＜0.0549) and a high RPR group (≥0.0549). Patients in the high RPR group were older, had a later Ann Arbor stage, were prone to bone marrow invasion, and had a higher National Comprehensive Cancer Network International Prognostic Index score (P ＜ 0.05). A survival analysis showed that progression-free survival (PFS) (P =0.003) and overall survival (OS) (P ＜0.0001) were significantly shorter in the high versus low RPR group. A multifactorial Cox analysis showed that bone marrow invasion and elevated lactate dehydrogenase (LDH) were separate risk factors for PFS (P ＜0.05), while an RPR ≥0.0549 and elevated LDH were separate risk factors for OS (P ＜0.05). Conclusion A high RPR (≥0.0549) in patients with newly diagnosed DLBCL is an independent risk factor for a poor prognosis.

Objective: To investigate the epidemiological characteristics and associated factors of scoliosis in primary and secondary school students in Guangdong, and to provide guidance for scoliosis control. Methods: Using a stratified cluster random sampling method, a total of 38 649 students aged 9-18 were selected from 132 primary and secondary schools in the Pearl River Delta and non Pearl River Delta cities for scoliosis screening and related associated factors questionnaire survey from September to October 2020. Results: A total of 1 440 students were detected with scoliosis, with a detection rate of 3.73%. The detection rate of girls was 4.90%, which was higher than that of boys at 2.66%( χ 2=386.89, P <0.01). The detection rate in the Pearl River Delta region was 4.09%, which was higher than the non Pearl River Delta region at 3.38%( χ 2=13.22, P <0.01). The detection rate in urban areas was 4.51%, which was higher than counties at 2.79%( χ 2=78.70, P <0.01). The detection rate increased with the increase of the school period, high school (5.94%)>junior high school (4.50%)>elementary school (1.35%)( χ 2=386.89, P <0.01). Multivariate Logistic regression analysis showed that region, urbanicity, gender, educational stage, exercise, using electronic mobile devices, nutritional status are the influencing factors for scoliosis ( OR=0.41-3.78, P <0.05). Conclusion The detection rate of scoliosis in primary and secondary school students in Guangdong Province varies by gender, urbanicity and educational stages. Female students, as well as junior and senior high school students should be paid more attention.

Objective: To describe the prevalence and relationship between moderate to vigorous physical activity(MVPA), screen time (ST) and depressive symptoms among middle school students in Guangzhou, and to provide a reference for adolescent depression prevention and control. Methods: Using stratified cluster random sampling method, a total of 2 140 students were selected from one urban area and one suburban country for MVPA, ST and depressive symptoms investigation. Logistic regression was used to analyze relations among MVPA, ST and their combined patterns for depressive symptoms. Results: A total of 89.72% students failed to meet the MVPA recommendations, girls (95.52%) were higher than boys(84.38%). Totally 67.38% of the students failed to meet the ST recommendations, boys (69.75%) were higher than girls(64.81%). The prevalence of depressive symptoms was 27.01%, girls (31.58%) higher than boys(22.80%). MVPA, ST failure compliance rate and depression symptoms detection rate of vocational high school and ordinary high school were higher than junior high school ( χ 2=6.40,121.71,27.37, P ＜ 0.05 ). Logistic regression analysis showed that the OR for depressive symptoms was 1.19 ( P =0.35) in students whose MVPA time achieving 1 h<7 d in the last week, and was 1.93 ( P <0.01) in students with the ST>2 h/d independently, no significant interactions were observed. Students with both MVPA time 1 h<7 d in the last week and the ST>2 h/d were more likely to report depressive symptoms( OR=2.03, P <0.05). Conclusion Insufficient MVPA, prolonged ST and high prevalence of depressive symptoms are observed among middle school students in Guangzhou. Students with both insufficient MVPA and prolonged ST are more likely to suffer from depressive symptoms. Specific psychological care and health education regarding physical activity and screen behavior should be implemented to students with different characteristics, as well as their parents for depressive symptom prevention.
