Chronic insomnia affects 10%–15% of the population, with one-third of Western adults struggling with sleep initiation or maintenance. Binaural beats, which involve two audio frequencies, have shown the potential for enhancing sleep and mood. This study examined the efficacy of customized binaural audio tracks generated using facial analysis software to treat chronic insomnia. Methods: A 45-minute personalized binaural beat audio session was delivered using the Spatial app and headband (SoundHealth) to 20 participants with moderate-to-severe insomnia, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and Insomnia Severity Index (ISI) criteria, over four weeks in California. Statistical analysis (paired t-test and linear mixed modeling) was used to compare baseline ISI scores to posttreatment scores, with p<0.05 indicating significance. The study assumed 80% power and aimed to achieve a 7-point ISI reduction. Results: All participants completed the study with no adverse events or full protocol adherence. The cohort was 60% White, with a 3:1 female-to-male ratio and an average age of 51.9 years. The baseline ISI was 19.8, dropping to 8.5 after four weeks, showing an 11.3-point reduction (95% confidence interval [CI]: -15 to -7.6, p<0.001). Mixed modeling indicated a similar ISI decrease of 11.28 points (95% CI: -14.98 to -7.57, p<0.001). The treatment response rate was 70%. Conclusions: Customized binaural beats show promise for insomnia treatment, with no adverse effects and high adherence. Most participants improved to no insomnia or subthreshold insomnia. Further research is needed to validate these results using larger samples and to assess long-term effects.

Objective: To develop a modified calculation formula for renal tumor volume and tumor contact surface area (CSA) based on the modeling results of 3D Slicer software, and to create a webpage of the calculation formula for use. Methods: The general information and tumor anatomical data of 98 patients who underwent partial nephrectomy during Jan.2021 and Jul.2023 in the Second Affiliated Hospital of Xi'an Jiaotong University were retrospectively analyzed.The imaging data were input into 3D Slicer software in the form of Dicom files for tumor and ipsilateral kidney modeling to obtain tumor anatomical data.The relationship between tumor anatomical parameters and tumor volume and CSA was analyzed using multifactorial linear regression.The initial modified formulas (V2, C2) and the optimized modified formulas (V3, C3) for tumor volume over CSA were established, respectively, after insignificant variables were eliminated.The mean square error (MSE) and Akaike information criterion (AIC) of the modified and traditional formulas (V1, C1) were compared, and the formula with the smallest MSE and AIC was selected as the optimal tumor volume and CSA calculation formula.The median tumor volume and CSA obtained from 3D modeling were used as the cutoff values.The optimal formula and conventional formula were applied to calculate tumor volume and CSA for all patients, and risk stratification was performed for all patients based on these cutoff values, and the perioperative indicators of patients in the upper and lower groups were compared.Finally, an online calculation tool was developed based on HTML. Results: Based on multifactorial linear regression analysis, we obtained the modified tumor volume calculation formula: V=0.382abc+2.488a+2.372b－4.146c+1.948（V2）, V=0.469abc－4.586c+13.816（V3）; the modified tumor CSA calculation formula CSA=2.469a －2.262L －19.23a+6.206b+1.212c+18.017L+1.616h－3.97h －2.185h/h －0.388（C2）, CSA=2.376a －2.144L －20.157a+5.024b+1.128c+17.578L+2.525h－2.634（C3）.Both of the modified volume formula (MSE=151.298 vs. 127.807 vs. 104.106) and modified CSA formula (MSE=309.878 vs.23.556 vs.30.388) had smaller errors compared to the conventional formula.The modified volume calculation formula showed that bleeding was more and thermal ischemia time was longer in patients with larger tumor volumes than in patients with smaller tumor volumes (P<0.05); and the modified CSA calculation formula showed that bleeding was more, surgery and thermal ischemia time were longer in patients with high CSA than in patients with low CSA (P＜0.05).Finally, V3 and C3 are selected as the best calculation formula, and a web page (https://lizihao-bot.github.io/RCC-Calculate/) was established for easy use. Conclusion: This study combined data from a medical information technology platform with numerical modeling methods to provide a faster and more accurate method to calculate the renal tumor volume and CSA.Meanwhile, a webpage version of the tool was developed to enhance its practicability.

BACKGROUND: China has made significant progress in medical accessibility and quality over the past decades, and quality improvements in gastroenterology and digestive endoscopy have been consistent. The study aimed to describe the status quo of gastroenterology and digestive endoscopy in the Chinese mainland based on the data from the National Clinical Improvement System (NCIS) and the Hospital Quality Monitoring System (HQMS). METHODS: Data were extracted from the NCIS and the HQMS. Data analysis included general information from the Department of Gastroenterology and Endoscopy centers, management of inpatients and outpatients, and annual volume and quality indicators of digestive endoscopy. Acute pancreatitis, gastrointestinal bleeding, inflammatory bowel disease, and cirrhosis were identified as priority diseases and were subjected to detailed analysis. RESULTS: Data from 4620 and 7074 hospitals were extracted from the NCIS and HQMS, respectively. In 2023, 9.6 gastroenterologists, 6.7 endoscopists, and 37.3 gastroenterology beds per hospital nationwide were observed, achieving 19,252.4 outpatient visits, 1615.2 hospitalizations (97.0 for acute pancreatitis, 146.1 for gastrointestinal bleeding, 40.2 for inflammatory bowel disease, and 111.4 for cirrhosis), and 9432.7 digestive endoscopic procedures per hospital. Overall, the quality of practice improved significantly. The proportion of early cancer among gastrointestinal cancers increased from 11.1% in 2015 to 23.4% in 2023, and the adenoma detection rate during colonoscopy increased from 19.3% in 2019 to 26.9% in 2023. Regarding priority diseases, hospitalizations increased, and 31-day unplanned readmission rates decreased between 2019 and 2023. The median hospitalization costs and median proportion of medication costs decreased for acute pancreatitis, gastrointestinal bleeding, and cirrhosis. However, it increased for inflammatory bowel disease. CONCLUSION This report evaluates the status quo and development of gastroenterology and digestive endoscopy in the Chinese mainland, providing guidance for future quality improvements.

OBJECTIVE: In order to enhance the efficacy of anti-breast cancer, paclitaxel nanoparticles (PTX NPs) and polypyrrole nanoparticles (PPy NPs) were combined with photothermal therapy and chemotherapy. At the same time, the two dosage forms of PTX NPs and PTX NPs gel were compared. METHODS: PTX NPs were prepared by self-assembly method, and then the cytotoxicity in vitro was investigated by Methyl thiazolyl tetrazolium (MTT) and other methods, and the efficacy and side effects in vivo were further investigated. RESULTS: The average hydrated diameter, PDI and electric potential of PTX NPs were (210.20 ± 1.57) nm, (0.081 ± 0.003) mV and (15.80 ± 0.35) mV, respectively. MTT results showed that the IC₅₀ value of PTX NPs on 4 T1 cells was 0.490 μg/mL, while that of PTX injection was 1.737 μg/mL. The cell inhibitory effect of PTX NPs was about 3.5 times higher than that of PTX injection. The tumor inhibition rates of PTX NPs and gel were 48.64% and 56.79%, respectively. Together with local photothermal stimulation, the tumor inhibition rate of the PTX NPs reached 91.05%, surpassing that of the gel under the same conditions (48.98%), moreover, the organ index and H&E staining results of PTX NPs showed a decrease in toxicity. CONCLUSION This combination therapy can significantly enhance the effect of anti-breast cancer, and the synergistic effect of chemotherapy and light and heat provides a feasible and effective strategy for the treatment of tumor.

Objective: To understand the prevalence of Lying Flat behaviors and its association with depressive symptoms among Chinese college students, so as to provide a scientific basis for promoting the physical and mental health development of adolescents. Methods: From July to October 2023, three universities were selected through convenient sampling from Jiangxi Province, Liaoning Province and Beijing City, respectively. Selfdesigned questionnaire links were distributed on campus to collect basic information and Lying Flat behaviors among college students, and the Patient Health Questionnaire-9 (PHQ-9) was utilized to screen for students with depressive symptoms. Finally, a total of 4 225 valid questionnaires were obtained. Chisquare was used to compare of report rates of Lying Flat behaviors across different demographic characteristics. Ordered Logistic regression analysis was used to explore the association between Lying Flat behaviors and depressive symptoms, with Z test used to assess variations in the strength of associations. Results: The reporting rates of academic, life, and social Lying Flat were 32.7%, 17.8% and 17.5%, respectively. And 6.7% of the participants were found of all three Lying Flat behaviors simultaneously.Among college students with three Lying Flat behaviors, the constituent ratios of no, mild, moderate and above depressive symptoms were 9.9%, 30.5% and 59.6%, respectively. Additionally, college students who had three Lying Flat behaviors were more likely to show mild, moderate and above depressive symptoms [OR(95%CI)=2.49(1.60-3.87), 7.69(5.01-11.79), P<0.01]. Conclusions Academic Lying Flat behavior is most prevalent among college students. Academic, life and social Lying Flat behaviors are all significantly positively correlated with depressive symptoms. Attention should be paid to the Lying Flat behaviors and college students psychological health conditions to promote their physical and mental health development.

【Objective】 To examine risk factors for acute pancreatitis (AP) in individuals with chronic alcohol consumption habits. 【Methods】 The study incorporated participants from the initial survey (2006-2010) and subsequent follow-ups (2014+) taken from the UK Biobank database, with the observation period ending on November 30, 2022. During this period, 176 individuals were newly diagnosed with AP, while 59,512 remained unaffected. Vital characteristics of the target population, such as their medical histories, surgical experiences and dietary patterns, were collected during the enrolment phase (2006-2010). The Cox proportional hazard model was employed to ascertain whether these characteristics were potent risk factors for AP. Concurrently, a subgroup from the target population with documented drinking behavior was selected. The multivariate Cox proportional hazard model was utilized to analyze the relationship of the established factors, variances in alcohol consumption, and increased alcohol intake (Δ) with the onset of AP, and whether the additional alcohol intake served as a risk factor. 【Results】 Multivariate analysis revealed that consumption quantity of cooked vegetables inversely correlated with AP risk (HR=0.44, 0.39, 0.42 and 0.41 for one, two, three and four+ tablespoons per day, respectively, as compared to non-consumers). Coffee consumption (2-3 cups per day) also reduced AP risk (HR=0.45 for 2 cups/day; HR=0.39 for 3 cups/day as compared to non-coffee drinkers). However, those with biliary disease without cholecystectomy exhibited a marked increase in AP risk (HR=7.82), which reduced albeit remained elevated for those with biliary disease post-cholecystectomy (HR=2.15). Subgroup analysis showed minimal impact of alcohol intake levels on AP incidence. Yet, increased alcohol consumption (Δ of 1 bottle/week) was linked to a heightened AP risk (HR=1.05, 95% CI:1.02-1.09, P<0.05). 【Conclusion】 Among longstanding alcohol consumers, a diet rich in cooked vegetables and moderate coffee consumption offers protective effects against AP. Conversely, biliary disease (particularly without cholecystectomy) and elevated alcohol intake present considerable risk factors for the development of this condition.

Objective:To compare the parameters for infra-acetabular screw placement between men and women using a digital Chinese anatomical model of the pelvis and acetabulum.Methods:The normal pelvic CT data were collected from the 163 adult patients who had been admitted to the Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2021. There were 61 males and 102 females with an age of 53.0 (45.0, 60.0) years. Mimics 21.0 software was used to reconstruct the three dimensional pelvis which was then imported into Autodesk maya 2022 software before the model was flattened. Polygonal modeling tools were used to create a cylinder to simulate an infra-acetabular screw for length and angle measurements of the screw. The diameters of the infra-acetabular screws were measured by axial fluoroscopy in Mimics 21.0 software. The maximum diameters and maximum lengths of the infra-acetabular bone channel were compared between males and females, and the angles between the axis of the infra-acetabular screw and the anterior pelvic plane and the median sagittal plane were also compared between genders.Results:The maximum diameters of the left and right infra-acetabular corridors were 5.24 (4.26, 6.38) mm and 5.04 (4.50, 6.57) mm in males, and 3.99 (3.81, 4.51) mm and 3.89 (3.65, 4.90) mm in females; the maximum lengths of the left and right infra-acetabular corridors were (98.43±4.42) mm and (98.01±5.08) mm in males and 87.73 (84.22, 90.98) mm and 87.51 (84.59, 90.15) mm in females. The left and right angles between the infra-acetabular screw axis and the median sagittal plane were -0.98°±4.79° and -1.08°±4.91° in men, and 6.20° (3.34°, 11.16°) and 6.44° (3.77°, 11.85°) in women. The differences in the above data between men and women were statistically significant ( P<0.05). There was no statistically significant difference between men and women in the angle between the infra-acetabular screw axis and the anterior pelvic plane ( P>0.05). Conclusions:The length and diameter of the infra-acetabular corridor in males are greater than those in females, the angle between the infra-acetabular corridor and the sagittal plane in males is smaller than that in females, and the infra-acetabular corridor in males is more parallel to the sagittal plane. Therefore, the fluoroscopy angle should be adjusted for males to reduce the difficulty in screw placement when an infra-acetabular screw is placed during surgery.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.
