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.

To summarise the clinical experience of Professor TONG Xiaolin in treating prediabetes combined with overweight or obesity using the method of relieving depression and reducing turbidity. It is believed that prediabetes belongs to the category of "spleen-heat syndrome" in traditional Chinese medicine， and its core pathogenesis is center fullness with internal heat， while obesity is the initiating factor for exacerbating center fullness and internal heat， therefore， it is of great significance to reduce the risk of diabetes by interrupting the transformation between overweight， obesity and glucose metabolism abnormality. It is proposed that the main pathogenesis of prediabetes combined with overweight or obesity is qi depression and turbidity obstruction in middle jiao， with qi depression as the root and turbidity obstruction as the cause， forming a treatment idea with the method of relieving depression and reducing turbidity as the core. In clinic， Dahuang Huanglian Xiexin Decoction （大黄黄连泻心汤） is used as the basic prescription， with a primary focus on directing the turbid downward， supplemented by regulating qi， which embodies the concept of "promoting movement through descent， then figuring out the root of spleen-heat syndrome. Furthermore， the treatment is flexibly modified based on the patient's deficiency-excess syndrome to ensure individualized therapy.

Objective:To estimate the influence of metabolic parameters in 18F-FDG PET/CT and clinically relevant indicators on the prognosis of patients with cervical cancer. Methods:A total of 174 patients with cervical cancer (age (53.6±11.1) years) who underwent baseline 18F-FDG PET/CT examination in the Affiliated Hospital of Qingdao University from May 2011 to December 2020 were retrospectively collected. Metabolic parameters (metabolic tumor volume of primary lesion (MTV p), total lesion glycolysis of primary lesion (TLG p), MTV sum of total lesions (MTV total) in the whole body, TLG sum of total lesions (TLG total)) and clinical parameters (International Federation of Gynecology and Obstetrics (FIGO) stage, tumor maximum diameter ( Dmax), et al) were collected. Cox regression and Kaplan-Meier method were performed to evaluate the prognostic and predictive values of those parameters. Results:The follow-up time was 6-120 months, during which 52 patients (29.9%, 52/174) developed progression. The 5-year overall survival (OS), progression-free survival (PFS), local control (LC) and distant metastasis-free survival (DMFS) rates were 83.3%(145/174), 70.1%(122/174), 75.3%(131/174) and 82.8%(144/174), respectively. Cox regression showed that FIGO stage and MTV total were independent factors for predicting PFS, OS and LC (hazard ratio ( HR): 1.005-11.605, all P<0.05). FIGO stage and TLG total were independent factors for predicting DMFS ( HR: 1.002-12.258, all P<0.05). Conclusion:MTV total and FIGO stage are effective predictors of patients with cervical squamous cell carcinoma.

Neurodegenerative diseases are often associated with inflammatory mechanisms, where persistent or excessive inflammatory responses can lead to neuronal damage and subsequent pathological changes. In acute neurological conditions such as stroke or traumatic brain injury, inflammation is a key factor that triggers acute neuronal injury and long-term sequelae. In chronic neurodegenerative diseases, including Alzheimer's disease, cognitive dysfunction, Parkinson's disease, and multiple sclerosis, the chronic activation of inflammation is closely related to gradual degeneration of neurons. Resolvin D1 (RvD1), an endogenous pro-resolving mediator, plays a crucial role in controlling the intensity and duration of inflammation by inhibiting excessive activation of immune cells, modulating the release of pro-inflammatory cytokines, and maintaining the integrity of the blood-brain barrier. This review focuses on the mechanisms of RvD1 in mediating inflammatory damage in major neurological diseases, aiming to provide theoretical support for a deeper understanding of disease mechanism, optimized therapeutic strategies, and enhanced outcome.

Objective To explore the clinical value of shear wave elastic imaging(SWE)for renal cortical elasticity in patients with hypertension.Methods According to the diagnostic criteria of 2020 International Society of Hypertension(ISH)Global Hypertension Practice Guidelines,44 patients with simple hypertension admitted to the Department of Cardiology of our hospital were selected and 46 healthy controls were selected for the same period.The general data and and renal function indicators of blood biochemical were recorded.All subjects were examined by two-dimensional ultrasound and SWE elasticity to obtain the conventional ultrasound parameters and the Young's modulus(YM)value of the right.The above parameters between the two groups were compared.The influence factors were analyzed by multiple linear regression among the YM value of the right renal cortex,the general data,conventional ultrasound indicators and renal function indicators in the simple hypertension group.Results The course,systolic blood pressure(SBP)and diastolic blood pressure(DBP)in the simple hypertension group was higher than those in the control group,and the difference was statistically significant(P＜0.05).The YM value of the right renal cortex in the simple hypertension group was higher than that in the control group,and the difference was statistically significant(P＜0.05).The correlation analysis showed that the YM value of the right renal cortex was positively correlated with the duration of hypertension(P＜0.05),but not with age,blood pressure,right renal volume,right renal cortex thickness,right renal artery trunk peak systolic flow velocity(PSV),right renal artery trunk resistance index(RI),blood urea nitrogen,blood creatinine,or uric acid(P＞0.05).Further simple linear regression analysis showed that the duration of hypertension was an independent factor affecting the YM value of the right renal cortex.Conclusion SWE may be used to find the variation in elasticity of renal cortex in patients with simple hypertension.

"State-target medicine" is a traditional Chinese medicine （TCM） diagnosis and treatment theoretical system proposed by Academician Tong Xiaolin based on the current development of modern medicine. The active stage of gastric ulcer， as a precancerous state of gastric cancer， has a great impact on people's health. Prof. ZHOU Xuewen， a master of TCM， innovatively put forward the theory of "toxicity-heat" etiology for the active stage of gastric ulcer， which plays an important guiding role in clinical diagnosis and treatment. The article took the theoretical system of "state-target medicine" as the framework to explain the rationale， method， formula， and medicine of Prof. ZHOU Xuewen， who applied the Xiaoyong Kuidekang based on the "toxicity-heat" theory to treat the gastric ulcer in the active stage. The Chinese medical name of gastric ulcer， "gastric carbuncle"， was established， and it was believed that gastric ulcer is born due to "toxicity" and is based on "toxicity and heat". In the course of the disease， "toxicity"， "heat"， "deficiency"， and "stasis" coexisted， and its pathogenesis was divided into three phases， namely， toxicity-heat accumulation phase， toxicity-heat affecting the health phase， and weakened body resistance and strengthened toxicity phase. According to the positioning of gastric ulcer as an "internal carbuncle"， Prof. ZHOU Xuewen proposed the treatment of gastric ulcer in the active stage with "carbuncle theory" and introduced the surgical methods of "elimination"， "support"， and "tonifying" into the treatment of gastric ulcer in the active stage. Prof. ZHOU Xuewen took "clearing heat and removing toxins， eliminating carbuncle and generating muscle" as the basic treatment of the disease. For different stages of the disease， Prof. ZHOU Xuewen emphasized the use of the methods of clearing heat and removing toxins， supporting rot and muscle growth， and strengthening the spleen and harmonizing the stomach and created the representative formula for the treatment of gastric ulcer in the active stage with "carbuncle theory"， namely "Xiaoyong Kuidekang"， which could regulate state and targets.

Breast cancer （BC） ranks first in the incidence rate of female malignant tumor， the notable features of which include high invasive behavior， high malignant degree and poor prognosis. Resveratrol， a plant antioxidant， has been identified as a potential therapeutic agent for the occurrence and progress of BC. This article explores the mechanism of resveratrol intervention in BC by evaluating several in vitro and in vivo studies. It was found that resveratrol can weaken the proliferation and survival ability of BC cells， suppress their growth， metastasis， and invasion， and reverse their resistance to adriamycin by promoting cell apoptosis， regulating autophagy， inhibiting glycolysis and regulating the tumor microenvironment， expressions of matrix metalloproteinases， epithelial-mesenchymal transition and drug-resistant proteins， etc. The limited number of clinical trial studies on resveratrol， mainly focusing on prevention effect of it on breast cancer， may be one of the reasons that affect the comprehensive evaluation of the anti-cancer efficacy of resveratrol.

Objective:To explore the effects of dual task training assisted by a lower limb rehabilitation robot on lower extremity mobility and the walking ability of stroke survivors.Methods:Sixty-one stroke survivors were randomly divided into a control group and an experimental group with 30 in the control group and 31 in the experimental group. In addition to routine exercise training and physical therapy, both groups were given cognitive-motor dual task training 5 times a week for 3 weeks. But only in the experimental group was the dual task training assisted by a lower limb rehabilitation robot. Both groups′ lower limb motor function, walking ability, cognition, balance and ability in the activities of daily living were evaluated before and after the experiment using the Fugl-Meyer lower extremity assessment (FMA-LE), functional ambulation categories (FAC), the digital span test (DST), the Berg Balance Scale (BBS) and the Modified Barthel Index (MBI). Additionally, 6 survivors of a right hemisphere stroke from the experimental group received cognitive-motor dual task training both with and without the robotic assistance alternately. Near-infrared functional brain imaging was applied before and after the intervention, and the functional network connectivity of the resting brains was analyzed.Results:After the intervention the average FMA-LE, FAC, BBS and MBI scores had improved in both groups, with the improvement in the experimental group significantly better than in the control group on average. In terms of cognition there was no significant difference in the DST forward and backward assessment results between the two groups. The analysis of brain network functional connectivity showed that the intensity of functional connectivity between the left prefrontal cortex (PFC) and the left premotor cortex and supplementary motor cortex (PMC/SMA) increased significantly more, on average, after training assisted by the robot.Conclusion:Dual task training with the assistance of a lower limb rehabilitation robot can effectively improve the lower limb motor function, walking, balance and ability in the activities of daily living of stroke survivors. Enhanced functional connection of the PFC and the PMC/SMA in the healthy hemisphere induced by the robot may be the cause.

Objective To explore the effect of deep learning image reconstruction(DLIR)algorithm combined with"double low"[low voltage(kV)and low contrast agent dosage]technique on the image quality of coronary computed tomography angiography(CCTA)in overweight patients compared with adaptive statistical iterative reconstruction(ASIR-V)and filtered back projection(FBP).Methods Fifty-two patients with body mass index(BMI)between 25.1 kg/m2and 28 kg/m2 who underwent CCTA scanning were prospectively selected,all of whom scanned on a GE Revolution APEX-CT with a tube voltage of 80 kV,a smart mA(500-1 300 mA),a noise index of 30,and a contrast dosage of 0.5 mL/kg;four groups of images were reconstructed for each patient,FBP,50％ASIR-V,DLIR-M,and DLIR-H.The CT and SD values of the aorta(AO)root,the proximal segment of the right coronary artery(RCA),the left circumflex(LCX),the left anterior descending branch(LAD)and the pericardial fat were measured,and the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.Two doctors experienced in the diagnosis of cardiovascular disease were selected to subjectively score the reconstructed images using a double-blind method.The SD value,SNR value,CNR value and subjective scores of images in the four groups were compared.Results In the objective image quality evaluation,there were statistically significant differences in SD value,SNR value and CNR value of reconstructed images in the four groups(P＜0.05).As the four groups of reconstruction algorithms FBP,50％ASIR-V,DLIR-M,and DLIR-H were changed sequentially,the image SD value gradually decreased,the SNR value and CNR value gradually increased,and the DLIR-H group had the lowest SD value and the highest SNR and CNR values.In the subjective image quality evaluation,the subjective scores of the two doctors had good consistency(Kappa value=0.900),and the difference between them was statistically significant(P＜0.001).The subjective scores of DLIR-M and DLIR-H groups were higher.Conclusion DLIR algorithm combined with"double-low"technique can significantly improve the CCTA image quality of overweight patients,which is better than 50％ASIR-V and FBP.
