Objective@#To describe the prevalence and association of dietary rhythm and depressive symptoms among adolescents, so as to provide a basis for improving unhealthy behavioral habits,and to promote adolescent physical and mental health.@*Methods@#From October to December 2021, a total of 22 868 students were selected from one middle school and high school in urban and rural areas of eight cities, namely, Shenyang, Xuzhou, Shenzhen, Taiyuan, Nanchang, Zhengzhou, Chongqing, and Kunming cities, China, using a combination of purposive sampling and stratified cluster random sampling. A self administered questionnaire was used to assess adolescents dietary rhythm, and the Patient Health Questionnaire-9 (PHQ-9) was used to assess depressive symptoms. Binary Logistic regression model was employed to analyze the associations between adolescent dietary rhythm and depressive symptoms, while the associations between adolescent dietary rhythm and depressive symptoms across gender and physical activity levels were stratified by gender and physical activity levels.@*Results@#The detection rate of depressive symptoms in adolescents was 44.4%. The respective differences in the detection rates of depressive symptoms among adolescents of different genders, physical activity levels, and dietary rhythm disorders were statistically significant ( χ 2=157.51, 105.02, 3 282.50, P <0.01). Taking the low disordered dietary rhythm group as the reference, binary Logistic regression analyses showed that after adjusting for confounding factors such as age, gender，family location, family economic situation, whether only child, parental education level, and learning burden, physical activity levels, depressive symptoms were positively correlated with adolescents in the moderate disordered dietary rhythm group ( OR=2.63, 95%CI =2.45-2.83) and the high disordered dietary rhythm group ( OR=6.38, 95%CI = 5.93- 6.86). In addition, after stratifying by gender, dietary rhythm were positively correlated with depressive symptoms. The moderate disordered group (male: OR=2.62, 95%CI =2.37-2.89, female: OR=2.67, 95%CI =2.40-2.97) and the highly disordered group (male: OR=5.74, 95%CI =5.19-6.35, female: OR=7.11, 95%CI =6.40-7.89) were positively correlated with depressive symptoms. After stratification by physical activity levels, low, moderate and above physical activity levels among adolescents in the disordered dietary rhythm group (low physical activity: OR=2.91, 95%CI =2.58-3.29, moderate and above physical activity: OR= 2.50, 95%CI =2.28-2.74), high disordered group (low physical activity: OR=6.51, 95%CI =5.94- 7.13 , moderate and higher physical activity: OR=6.18, 95%CI =5.47-6.97) were positively associated with depressive symptoms ( P <0.01). There was an interaction between dietary rhythm and physical activity levels in regard to the development of depressive symptoms in adolescents, taking the group with moderate and above physical activity levels and low disordered dietary rhythm as the reference,the detection rate of which was higher in adolescents with low levels of physical activity and those in the moderate or high disordered dietary rhythm group ( OR=1.50, 3.90, 95%CI=1.39-1.61, 3.63-4.19, P <0.01).@*Conclusions@#Dietary rhythm disorders were found to be positively associated with depressive symptoms in adolescents. Regular dietary behaviors and increased physical activity play an important positive role in promoting adolescent mental health.

Objective To investigate the status and the influencing factors of thyroid volume of children aged 8-10 years in Tianjin. Methods Among the 1-2 primary schools were randomly selected from 12 districts in Tianjin. A total of 1 090 children were selected by class cluster sampling method (half male and half female, with a balanced age distribution). A questionnaire survey was conducted. Children’s height, weight and thyroid volume were measured, and their salt iodine content and urinary iodine content were detected. Results I n this study, the median urinary iodine in children was 161.35 µg/L, the mean thyroid volume was 2.56 mL, and the goiter rate was 3.58%. Univariate analysis showed that age, BSA, salt iodine content, urinary iodine content, eating habits, food taste, eating lunch at school, father's work, anxiety and depression, pressure, and different regional grouping were the influencing factors of thyroid volume (P<0.05). Multivariate linear regression showed that BSA, age, food taste, and urinary iodine content had significant independent effects on thyroid volume (P<0.05). Conclusion In Tianjin, the iodine nutrition level of children aged 8-10 years is at an appropriate level. When evaluating the thyroid volume of children, in addition to age factors, other factors such as physical development level and iodine intake should also be considered.

BACKGROUND:Previous literature reported that the fusion cage moved more than 2 mm from its original position,which means that the fusion cage moved backward.At present,clinical observation has found that the factors leading to the displacement of the fusion cage are complex,and the relationship between these factors and the cage retropulsion is not clear. OBJECTIVE:To explore the risk factors related to cage retropulsion after lumbar interbody fusion. METHODS:Retrospective analysis was conducted in 200 patients who underwent transforaminal lumbar interbody fusion surgery with a polyetheretherketone interbody fusion from February 2020 to February 2022.According to the distance from the posterior edge of the vertebral fusion cage to the posterior edge of the vertebral body after the operation(the second day after the removal of the drainage tube)and 1,3,6 and 12 months after the operation,patients were divided into cage retropulsion group(≥2 mm)and cage non-retropulsion group(<2 mm).The factors that may affect cage retropulsion,such as age,gender,body mass index,bone mineral density,operation time,bleeding,endplate injury,preoperative and postoperative interbody height,cage implantation depth,cage size,and segmental anterior convexity angle,were analyzed by univariate and logistic regression analysis. RESULTS AND CONCLUSION:(1)Posterior displacement of the fusion cage occurred in 15 cases(15/200).The differences in basic information such as age and body mass index between the two groups were not statistically significant.(2)The results of the univariate analysis were that gap height difference,time to wear a brace,segmental anterior convexity angle difference,bone mineral density,and age were related to posterior migration of the cage.(3)The results of logistic regression analysis were that cage size,endplate injury condition,and depth of cage implantation were risk factors for cage retropulsion.(4)These findings suggest that cage retropulsion after lumbar interbody fusion is caused by multiple factors,including segmental anterior convexity angle difference,bone mineral density,cage size,endplate damage,time to wear a brace,and depth of cage implantation.

BACKGROUND:Superior lower limb mobility is regarded as one of the prerequisites for winning competitions.Wearable resistance training can effectively overcome the deficiency in the transfer efficiency of traditional strength training in enhancing lower limb mobility.Considering that the impact of wearable resistance training based on different body parts on lower limb mobility may have significant differentiated characteristics,it is particularly important to review and summarize the specific application strategies and acute and chronic intervention effects. OBJECTIVE:To comb and analyze acute and chronic intervention effects of wearable resistance training based on different body parts on lower limb mobility,in order to provide insightful and methodological references for optimizing application strategies for lower limb movement ability. METHODS:A literature search was conducted in CNKI,Wanfang,VIP,Web of Science,Medline,SPORTDiscus,and PubMed databases for publications up to October 2023.Chinese and English search terms were"arm,forearm,limb,leg,lower extremity,vest,trunk,resist,weight,load,sprint,agility,change of direction".A total of 60 articles were ultimately included for review after screening the retrieval results. RESULTS AND CONCLUSION:(1)Trunk loading of 6-20%of body mass is suitable for optimizing acceleration in sprinting,while trunk loading of≤6%body mass is suitable for optimizing high-speed running.A trunk load of 5%body mass is applicable for optimizing change-of-direction movement;forearm,calf,or thigh loading often uses 1%or 2%body mass.(2)Trunk loading optimizes the functional performance of the lower limb stretch-shortening cycle by increasing vertical load.This enhances the efficiency of ground reaction force utilization and strengthens the coordinated stability control of the whole body musculature.Forearm loading effectively enhances the driving force of the upper limb swing,improves the propulsive force of the lower limb sprint,and optimizes the efficiency of inter-limb coordination.Calf loading can impose restrictions on the function of the hip joint,thereby leading to localized load stimulation and compensatory functional enhancement in the knee or ankle joint.Thigh loading partially restricts the peak extension angle and speed of the knee joint,creates specific load stimulation at the hip joint,and significantly improves its rotational kinetic energy output.(3)During larger-angle change-of-direction movements,the impact of calf loading is more significant than thigh loading.Thigh loading stimulation helps to enhance power output,while calf loading stimulation aids in improving stability control and directional change.(4)Currently,wearable resistance training has been proven to be an effective way to improve sprint and change-of-direction performance.The methodological strategies to improve sprint performance are relatively mature,but the optimal application scheme to improve change-of-direction performance needs to be further refined and optimized.Further research is recommended to supplement this area.

Objective:To investigate the clinical outcomes and efficacy of trabecular metal (TM) cones for the reconstruction of metaphyseal bone defects in revision total knee arthroplasty.Methods:A retrospective analysis was conducted on 46 patients (47 knees), who underwent revision total knee arthroplasty with TM cones for metaphyseal defect reconstruction from July 2015 to August 2023. The cohort comprised 12 males and 34 females, ranging from 41 to 83 years of age, with a mean of 68.65 ± 9.09 years. Body mass index (BMI) ranged from 19.5 to 36.0 kg/m 2, averaging 27.20±4.50 kg/m 2. Bone defects were stratified according to the Anderson Orthopedic Research Institute (AORI) classification, including 64 sides (AORI T2B type 20 sides, T3 type 16 sides, F2B type 11 sides, F3 type 17 sides) which were addressed with 67 cones. Evaluations during follow-up included range of motion (ROM), visual analogue scale (VAS) for pain, and the American Knee Society Score (KSS). Long leg radiographs and knee X-rays were reassessed for femorotibial angle (FTA) and joint alignment, osseointegration of the TM cones, and any complications were documented. Results:The average follow-up duration was 46.22±26.55 months (range 16-103 months). The KSS knee score significantly improved from 29.22±19.79 preoperatively to 88.22±6.01 at the final follow-up ( F=258.118, P<0.001). Similarly, the KSS function score saw a marked increase from a preoperative average of 7.65±8.21 to 56.30±6.10 at the final follow-up ( F=354.711, P<0.001). VAS scores significantly decreased from 5.35±1.50 preoperatively to 0.28±0.50 at the final follow-up ( F=300.934, P<0.001). ROM improved from 67.72°±34.62° preoperatively to 85.33°±9.15° at the final follow-up ( F=7.798, P<0.001), and the FTA improved from 179.24°±10.30° preoperatively to 174.39°±1.69° at the final follow-up, a statistically significant enhancement ( F=9.123, P<0.001). Osseointegration was observed in 95.5% of the cases (64/67 cones). There were no instances of osteolysis or aseptic loosening observed, indicating stable prosthetic fixation. Complications were minimal, with one reported case of a femoral shaft fracture, which was successfully treated with internal fixation, resulting in satisfactory healing at 6 months. At the last follow-up (3 years after operation), the patient could walk at home with a walker and the other patients had no complications such as periprosthetic joint infection, dislocation and periprosthetic fracture. Conclusion:The application of trabecular metal cones in revision total knee arthroplasty provides an effective solution for the reconstruction of severe metaphyseal bone defects, enhancing prosthetic stability and restoring the knee joint's mechanical alignment. The trend towards successful osseointegration in the TM cones is promising, and a significant improvement in knee joint function has been observed.

Objective:To evaluate the effect of esketamine on learning and memory function after chronic stress and the signaling pathway of N-methyl-D-aspartate receptor (NMDAR)-calmodulin-dependent protein kinase type 2 (CaMKⅡ)-cAMP-responsive element-binding protein (CREB) in the hippocampus of developing rats.Methods:Sixty clean-grade healthy Sprague-Dawley rats of either sex, aged 7 days, weighing 10-15 g, were divided into 3 groups ( n=20 each) using a random number table method: control+ normal saline group (CN group), chronic stress+ normal saline group (NS group), and chronic stress+ esketamine group (ES group). A chronic stress model was established using a chronic unpredictable stress method. After the end of stress stimulation, esketamine 10 mg/kg was intraperitoneally injected once a day for 7 consecutive days in ES group, and the equal volume of normal saline was given instead in NS group. Y maze test and Morris water maze test were used to assess the learning and memory function after intraperitoneal administration. Venous blood samples were obtained to measure the serum cortisol and reactive oxygen species (ROS) concentrations by enzyme-linked immunosorbent assay. The animals were then sacrificed under anesthesia, the brain was removed and the hippocampal tissue was isolated for examination of the pathological changes in the hippocampal CA1 region and for determination of the ratios of phosphorylated NMDAR (p-NMDAR)/NMDAR, phosphorylated CaMKII (p-CaMKⅡ)/CaMKⅡ, and phosphorylated CREB (p-CREB)/CREB (by Western blot). Results:Compared with CN group, the time spent in the novel arm was significantly shortened, the number of entries into the novel arm was reduced, the escape latency was prolonged, the number of crossing the original platform was reduced, the serum cortisol and ROS concentrations were increased, the p-NMDAR/NMDAR ratio, p-CaMKⅡ/CaMKⅡ ratio and p-CREB/CREB ratio were decreased ( P<0.05), and the pathological changes of neurons were marked in NS group. Compared with NS group, the time spent in the novel arm was significantly prolonged, the number of entries into the novel arm was increased, the escape latency was shortened, the number of crossing the original platform was increased, the serum cortisol and ROS concentrations were decreased, the p-NMDAR/NMDAR ratio, p-CaMKⅡ/CaMKⅡ ratio and p-CREB/CREB ratio were increased ( P<0.05), and the pathological changes of neurons were significantly attenuated in ES group. Conclusions:Esketamine can improve the learning and memory function after chronic stress in developing rats, and the mechanism may be related to reduction of oxidative stress and enhancement of the activity of hippocampal NMDAR-CaMKII-CREB signaling pathway.

Anomalous aortic origin of the coronary artery(AAOCA) refers to the abnormal initiation, route, or distribution of coronary arteries, which is generally believed to be caused by abnormal or incomplete development of embryonic coronary arteries, and is a rare congenital cardiovascular malformation. It can exist independently without other congenital heart disease. With the development of medical science and people's understanding of AAOCA, more and more AAOCA has been detected, and its clinical significance has attracted more and more attention. Based on abnormal coronary artery opening, malignant or potential contorts can cause long-term blood flow dynamic change, appear abnormal blood vessel hardening of the arteries, at the same time due to walk in the pulmonary artery and the ascending aorta between two vessels, vulnerable to the extrusion of large blood vessels, which caused a temporary blood flow in coronary artery interruption, can cause acute angina pectoris, myocardial infarction, arrhythmia, exercise-induced cardiac syncope. This review focuses on the anatomy, diagnosis and treatment of coronary artery abnormalities arising from aorta.

Median OS time was not reached in patients with SEER stage of localized lesions, 46 months (95% CI: 8-83 months) for regional lesions stage, and 9 months (95% CI: 5-12 months) for distant metastases stage ( P < 0.001). Of the patients with clear AJCC staging and some with unspecified AJCC staging, 118 received surgical treatment alone and 119 received postoperative radiotherapy, the median OS time of the two groups was 443 months (95% CI: 162-723 months) and 102 months (95% CI: 75-129 months), and the difference in OS between the two groups was statistically significant ( P < 0.001). Among the patients with AJCC stage Ⅰ, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 82.5% and 78.5%, the stage Ⅱ were 80.0% and 52.3%, and the stage Ⅲ were 27.8% and 63.3%, respectively; the differences in OS between different stages were not statistically significant (all P>0.05). Among the patients with SEER localized lesions stage, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 88.9% and 73.1%, and the difference was statistically significant ( P = 0.012); the regional lesions stage were 45.5% and 60.0%, and the difference was not statistically significant ( P = 0.568). The results of multivariate Cox regression analysis showed that AJCC staging (stage Ⅰ vs. stage Ⅳ, HR = 0.281, 95% CI: 0.178-0.543, P < 0.001; stage Ⅱ vs. stage Ⅳ, HR = 0.347, 95% CI: 0.113-0.439, P < 0.001; stage Ⅲ vs. stage Ⅳ, HR = 0.399, 95% CI: 0.030-0.145, P < 0.001), SEER staging (localized lesions stage vs. distant metastases stage, HR = 0.104, 95% CI: 0.059-0.182, P < 0.001; regional lesions stage vs. distant metastases stage, HR = 0.301, 95% CI: 0.195-0.463, P < 0.001) and whether or not receive surgery (yes vs. no, HR = 0.359, 95% CI: 0.241-0.535, P < 0.001) were independent influencing factors of OS in CCAC patients. Conclusions:AJCC staging, SEER staging and surgery are independent influence factors for OS in patients with CCAC, and postoperative radiotherapy may not provide more survival benefit.

This paper elucidates the connotation and extension of the concept of "impending illness" from the perspective of logic. The connotation of impending illness refers to the intermediate state between health （not yet sick） and disease （already sick）， characterized by the initial instability of yin and yang or a low-level balance of yin and yang as its internal mechanism， and mild dysfunctions in physiological， psychological， and social functions as its manifestations. The extension of impending illness includes latent disease status and pre-disease status. By adopting a creative hermeneutic approach to explore the deep-seated connotations of impending illness， this paper systematically analyzes the concept of impending illness from five levels： the existential level， the intentional level， the implicational level， the situational level， and the necessitational level， arguing that impending illness represents the unity of ambiguity and precision， the deviation of the human body system from homeostasis within a certain range， and an important component of the improvement of the traditional Chinese medicine health management system. Thoroughly explicating and clarifying the concept of "impending illness" can provide theoretical references for the study of transitional states between health and disease and the improvement of the traditional Chinese medicine health management system.

The essence of asymptomatic syndrome differenciation is that the disease is in a special stage or state. To perform traditional Chinese medicine （TCM） diagnosis when there was no symptoms for differentiation is a key scientific issue in current TCM diagnosis and treatment. The reasons include limitations in doctor-patient behaviors and relationships， as well as limitations in cognitive thinking. To address such situations， the following strategies can be adopted from a thinking perspective，i.e. grasping the occurrence and development of diseases based on a holistic concept， using dialectical thinking to summarize the laws of diseases， integrating clinical practice with experiential thinking， and introducing new thinking modes through interdisciplinary collaboration. These strategies help TCM practitioners make accurate diagnoses in the absence of obvious symptoms， thereby providing better medical services for patients.

The microcosmic syndrome differentiation is expounded from the the trinity life view of the body， qi， and spirit. This article analysed the relationship between micro-indicators and body， qi and spirit， considering that the abnormalities of micro-indicators in pathological states involve three different levels in terms of body， qi and spirit， and may reflect the degree of malfunction of body， qi and spirit and the dynamic changes of the focus during different pathological processes.Accordingly， based on the syndrome differentiation and treatment of traditional Chinese medicine， it is proposed that the macroscopic and the microscopic， the local and the whole， as well as the imbalance of body， qi and spirit reflected by microscopic and macroscopic indicators at different stages of disease should be combined to determine the corresponding treatment， thereby restoring the “harmony of body and spirit” of the human body.

【Objective】 To investigate the relationship of miRNA gene polymorphisms with blood pressure (BP) responses to the sodium and potassium diet intervention. 【Methods】 In 2004, we recruited 514 participants from 124 families in seven villages of Baoji, Shaanxi Province, China. All subjects were given a three-day normal diet, followed by a seven-day low-salt diet, a seven-day high-salt diet, and finally a seven-day high-salt and potassium supplementation. A total of 19 miRNA single nucleotide polymorphisms (SNPs) were selected for analysis. 【Results】 Throughout the sodium-potassium dietary intervention, the BP of the subjects fluctuated across all phases, showing a decrease during the low-salt period and an increase during the high-salt period, followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet. MiR-210-3p SNP rs12364149 was significantly associated with systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure (MAP) responses to low-salt diet. MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention. In addition, miR-26b-3p SNP rs115254818 was significantly correlated with SBP, DBP and MAP responses to high-salt intervention. MiR-1307-5p SNPs rs11191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet. MiR-4638-3p SNP rs6601178, miR-210-3p SNP rs12364149, miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet. In addition, miR-26b-3p SNP rs115254818 was significantly associated with SBP, DBP and MAP responses to potassium supplementation. MiR-1307-5p SNPs rs11191676, rs2292807, and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation. 【Conclusion】 miRNA gene polymorphisms are associated with BP response to sodium and potassium, suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.
