Objective: To evaluate the intervention effect of school based salt reduction health education, so as to provide a scientific basis for constructing a more effective and sustainable salt reduction intervention model for children. Methods: According to a randomized controlled trial design, in June 2022, probability proportional to size sampling was used to select 501 second grade students (248 in the control group and 253 in the intervention group) from 10 primary schools in Zhenjiang (intervention group) and 10 primary schools in Yangzhou (control group), Jiangsu Province. An one year school based salt reduction health education intervention was implemented. This included 20 online and 8 offline health education sessions, monitoring of salt consumption in the canteen, and the establishment of a salt reduction environment on campus. The control group received no additional salt reduction interventions. A questionnaire survey and 24 hour urinary sodium test were conducted before and after the intervention. The difference in differences method was used to evaluate the intervention effect. Results: After the intervention, the intervention group showed significant net intervention effects in knowledge aspects, including knowing that primary school students consume less salt than adults ( OR=3.55,95%CI =1.69-7.47), daily salt intake of primary school students ( OR=6.64,95%CI =3.71-11.87), long term high salt intake leading to hypertension ( OR=6.83,95%CI =3.93-11.91), low salt intake not causing hair graying ( OR= 1.66 ,95%CI =1.00-2.75), salt content in food labels ( OR=4.56,95%CI =2.63-7.91), and common high salt foods ( OR=3.39,95%CI =1.87-6.14) (all P <0.05). In terms of attitude, the net intervention effect for having a positive attitude toward using less salt in home cooking was significantly increased ( OR=1.88,95%CI =1.13-3.12, P <0.05). There were no statistically significant net intervention effects for salt reduction related behaviors (all P >0.05). There was no statistically significant difference in the changes of 24 hour urinary sodium between the intervention group and the control group before and after intervention ( P >0.05). Conclusions School based salt reduction health education effectively improves students salt reduction knowledge and attitudes but has a limited effect on behavior change. The home-school collaboration should be strengthened, and the dietary environment should be optimized simultaneously.

OBJECTIVE: To compare the effects of bilateral vertebral puncture guided by an angle-adjustable linear laser auxiliary device versus free-hand bilateral vertebral puncture. METHODS: A retrospective analysis was conducted on the clinical data of 47 patients who underwent thoracolumbar percutaneous kyphoplasty(PKP) from July 2022 to July 2023. All patients received bilateral percutaneous kyphoplasty, among whom 27 cases underwent conventional free-hand puncture (conventional puncture group) and 20 cases underwent puncture guided by a laser auxiliary device (auxiliary puncture group). In the conventional puncture group, there were 11 males and 16 females, with an average age of (69.6±5.1) years and a disease duration of (6.5±3.8) days;the fractured vertebrae were T₁₁-T₁₂ in 13 cases and L₁-L₂ in 14 cases. In the auxiliary puncture group, there were 7 males and 13 females, with an average age of (70.8±5.6) years and a disease duration of (6.4±3.8) days;the fractured vertebrae were T₁₁-T₁₂ in 7 cases and L₁-L₂ in 13 cases. The operation time, total blood loss, intraoperative fluoroscopy times, fluoroscopy duration, radiation dose, puncture success rate, and surgical complications were compared between the two groups. The visual analogue scale (VAS) was used to evaluate low back pain before surgery, 2 days after surgery, and 1 year after surgery. RESULTS: All patients achieved successful puncture, with good postoperative wound healing and no complications. The operation time of the auxiliary puncture group was (12.1±2.6) minutes, which was shorter than that of the conventional puncture group (14.1±2.8) minutes. The total blood loss of the auxiliary puncture group was (228.5±35.8) ml, less than that of the conventional puncture group (257.0±48.3) ml. The fluoroscopy times, fluoroscopy duration, and radiation dose of the auxiliary puncture group were (5.4±1.3) times, (15.9±3.3) seconds, and (159.4±37.4) μSv, respectively, all lower than those of the conventional puncture group (6.4±1.6) times, (18.8±4.6) seconds, (192.2±48.5) μSv, with statistically significant differences(P<0.05). There were no statistically significant differences in low back VAS scores between the two groups before surgery, 2 days after surgery, or 1 year after surgery(P>0.05). CONCLUSION Both laser auxiliary device-guided vertebral puncture and free-hand vertebral puncture have high success rates and similar postoperative curative effects. However, the laser auxiliary device-guided puncture has shorter operation time, less blood loss, and lower radiation hazard.

The connection between tendons and bones is called the tendon bone connection. With the continuous improvement of national sports awareness, excessive exercises and the related intensity are prone to damage the tendon bone connection. Tendon bone healing is a complex repair and healing process involving multiple factors, and good tendon bone healing is a prerequisite for its physiological function. The complexity of tendon bone structure also poses great challenges to the repair of tendon bone injuries. In recent years, researches have found that stem cells, growth factors, macrophages, and other factors are closely related to the healing process of tendon bone injuries, among which macrophages play an important role in the healing process. The authors reviewed relevant research literature in recent years and summarized the role of macrophages in tendon bone healing, in order to provide new ideas and directions for treatment strategies to promote tendon bone healing.

OBJECTIVE: This study aimed to explore the interplay between the life-course body mass index (BMI) trajectories and insulin resistance (IR) on incident diabetes. METHODS: This longitudinal cohort included 2,336 participants who had BMI repeatedly measured 3-8 times between 1989 and 2009, as well as glucose and insulin measured in 2009. BMI trajectories were identified using a latent class growth mixed model. The interplay between BMI trajectories and IR on diabetes was explored using the four-way effect decomposition method. Logistic regression and mediation models were used to estimate the interaction and mediation effects, respectively. RESULTS: Three distinct BMI trajectory groups were identified: low-stable ( n = 1,625), medium-increasing ( n = 613), and high-increasing ( n = 98). Both interaction and mediation effects of BMI trajectories and IR on incident diabetes were significant ( P < 0.05). The proportion of incident diabetes was higher in the IR-obesity than in the insulin-sensitivity (IS) obesity group (18.9% vs. 5.8%, P < 0.001). After adjusting for covariates, the odds ratios (95% confidence intervals) of the IR, IS-obesity, and IR-obesity groups vs. the normal group were 3.22 (2.05, 5.16), 2.05 (1.00, 3.97), and 7.98 (5.19, 12.62), respectively. IR mediated 10.7% of the total effect of BMI trajectories on incident diabetes ( P < 0.001). CONCLUSION We found strong interactions and weak mediation effects of IR on the relationship between life-course BMI trajectories and incident diabetes. IS-obesity is associated with a lower risk of incident diabetes than IR-obesity.

Objective: To understand the subjective and objective comfort evaluations of students from different age groups on desks and chairs, so as to provide reference for standardized allocation and use of desks and chairs. Methods: From January to April 2024, a total of 2 446 students were selected from 26 schools in 13 districts (counties/cities) in Shanghai, Tianjin, and Wuxi from Jiangsu Province by using cluster random method, including students in kindergartens, primary schools, junior high schools,senior high schools, colleges and universities. Standardized procedures were used to measure the height and weight of participants, and the matching desks and chairs models were selected according to the height. The subjective comfort of students on matching desks and chairs was investigated, and their objective comfort was evaluated by using a self designed questionnaire. The χ 2 test was used to analyze the differences of subjective perception and objective evaluation in comfort between different types of desks and chairs. Results: About 84.1% of the students subjectively thought that large desks and small chairs were very comfortable or relatively comfortable, followed by large desks and chairs (75.7%), and the proportion of small desks and chairs was the lowest among the three types (46.2%), and the difference was statistically significant ( χ 2=722.46, P <0.01). The reporting rates of primary school, junior high school and senior high school students who subjectively considered large desks and chairs to be very comfortable/relatively comfortable were higher than that of other types of desks and chairs, and the differences were statistically significant ( χ 2=297.49, 252.82, 343.67, P <0.01). However, there was no significant difference in the subjective comfort evaluation of different types of desks and chairs among kindergarten children ( χ 2=3.21, P >0.05), and 66.3% of the students in colleges and universities felt very comfortable/relatively comfortable when they used the matching standard desks and chairs. The objective evaluation results of the comfort for the three types of desks and chairs were consistent with the subjective evaluation, but the proportions of the objective evaluation as very comfortable/relatively comfortable were higher than that of the subjective evaluation ( χ 2=20.76- 813.47, P <0.01). Conclusions Large desks and chairs, as well as large desks with small chairs are perceived comfortable, while small desks and chairs are perceived less comfortable. It is recommended to match the large desks and chairs or large desks and small chairs that are suitable for them according to the "standard", to promote physical and mental health of students.

Objective:A nomogram model for predicting double positivity of microvascular invasion (MVI) and vascular endothelial-to-mesenchymal transition (VETC) in patients with hepatocellular carcinoma (HCC) was constructed and its predictive performance was evaluated.Methods:A retrospective analysis was conducted on 326 HCC patients who were treated at the Third People's Hospital of Nantong and the First Affiliated Hospital of Soochow University from January 2013 to June 2023, including 240 males and 86 females, with an average age of (58.7±9.0) years. The 326 patients were randomly divided into a training set ( n=228) and a test set ( n=98) at a ratio of 7: 3 using the random number table method. The training set was divided into a double-positive group ( n=54) and a control group ( n=174) based on whether the HCC patients were double positive for MVI and VETC. Univariate and multivariate logistic regression analyses were performed to identify the influencing factors of double positivity of microvascular invasion in HCC patients, and a nomogram for predicting double positivity of microvascular invasion patterns was constructed based on the multivariate. The predictive performance and clinical net benefit of the nomogram were evaluated using the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. Results:There were statistically significant differences in alpha-fetoprotein, gamma-glutamyl transferase, and phosphatidylinositol proteoglycan between the two groups (all P<0.05). Multivariate logistic regression analysis showed that LI-RADS category ( OR=8.58, 95% CI: 1.87-39.38), intratumoral hemorrhage ( OR=2.16, 95% CI: 1.14-4.07), and intratumoral arteries ( OR=2.59, 95% CI: 1.19-5.64) were all influencing factors of double positivity of microvascular invasion patterns in HCC patients (all P<0.05). Based on the multivariate results, a nomogram was constructed. In the training set, the area under the ROC curve for predicting double positivity of microvascular invasion patterns in HCC patients was 0.769 (95% CI: 0.720-0.814). In the test set, the area under the ROC curve for predicting double positivity of microvascular invasion patterns in HCC patients was 0.756 (95% CI: 0.622-0.850). The calibration curve showed a good fit between the predicted model and the ideal curve. Decision curve analysis showed that the clinical applicability was good when the threshold was 0.01-0.80 in the training set and 0.01-0.65 in the test set. Conclusion:The nomogram model based on LI-RADS category, intratumoral hemorrhage, and intratumoral arteries can effectively predict double positivity of microvascular invasion patterns in HCC patients and has good clinical applicability.

Objective To analyze the medication rules of traditional Chinese medicine in treating breast cancer based on real-world data mining.Methods Inpatients with breast cancer who received traditional Chinese medicine treatment at the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from January 2017 to December 2021 were selected.Python 3.10 software was used to mine traditional Chinese medicine prescription data;SPSS 23.0 software was applied for descriptive analysis,and systematic cluster analysis was performed on high-frequency drugs.Results A total of 3026 consultation records of inpatients with breast cancer were collected.The main traditional Chinese medicine syndrome diagnosis of"predominantly liver depression and Qi stagnation"accounted for 60.94％of the total consultations.A total of 240 kinds of traditional Chinese medicine were used,with a cumulative frequency of 35 462 times.Among them,29 kinds of traditional Chinese medicine such as Danggui,Fuling,Baizhu,Chaihu had a cumulative usage frequency exceeding 300 times.Regarding the four natures of drugs,cold-natured(43.55％),warm-natured(30.05％),and neutral-natured(23.34％)drugs were predominant;In terms of five flavors,sweet(46.12％),bitter(30.91％),and pungent(20.02％)were the main ones.The most frequently used drugs were tonifying herbs(32.77％),followed by heat-clearing herbs(15.96％)and phlegm-resolving herbs(14.71％).Systematic cluster analysis yielded 7 groups of drug combinations.Conclusion In real-world clinical practice,traditional Chinese medicine for breast cancer mainly uses tonifying herbs,reflecting the traditional Chinese medicine principle of"strengthening healthy Qi and cultivating the root"in treating tumors.The four natures and five flavors of drugs follow syndrome differentiation and the combination of cold and heat.The clustered drug combinations have extensive therapeutic effects,covering various syndromes of breast cancer at different stages,which can provide a reference for clinical medication.

A child aged 5 years with pulmonary arterial hypertension was admitted to the First Affiliated Hospital of Xiamen University in December 2017. A truncated mutation in the bone morphogenetic protein receptor 2 (BMPR2) gene [Chr2(GRCh37):g.203395656delA] was detected, which might be responsible for the disease and the diagnosis of hereditary pulmonary arterial hypertension (HPAH) was confirmed. Genetic testing revealed that the child′s father also carried the same mutation in BMPR2 gene, but no gene mutation was detected in child′s mother and young brother; however, no HPAH was developed in child′s father and other family members. The child was treated with targeted drugs for pulmonary arteries with poor response, and died in April 2019. Later, the child′s mother accidentally became pregnant. Gene sequencing test of the amniotic fluid showed that the fetus also carried the BMPR2 gene mutation; the pregnancy was terminated after genetic counseling. HPAH has the clinical characteristics of early onset, rapid progression, and poor prognosis, and the BMPR2 gene mutation is an important pathogenic factor. For HPAH patients with unknown etiology, particularly for pediatric patients, genetic testing is recommended to identify the cause and to make an appropriate clinical management plan.

Objective:To explore the correlation between serum uric acid/high-density lipoprotein cholesterol ratio (UHR) and the risk of hypertension in elderly physical examination populations.Methods:This study was a cross-sectional study. A total of 1 028 patients aged≥60 years who underwent physical examinations at the Health Management Center of Fuwai Central China Cardiovascular Hospital from September 2023 to February 2024 were included in this study. The general demographic data, past medical history, physical examination and laboratory examination indicators of the physical examiners were collected, and according to whether they had hypertension or not, they were divided into hypertension group (390 cases) and non-hypertension group (638 cases), and all UHR values were arranged from small to large, and the UHR was divided into three groups by tertiles of UHR, and the general data and blood biochemical indexes between the groups were compared. Spearman rank correlation was used to analyze the correlation between UHR level and body mass index, total cholesterol, triglyceride and other indexes in the elderly population. Logistic regression was used to explore the relationship between UHR level and hypertension in the elderly population, and the stratification analysis of the physical examination population was carried out according to diabetes, coronary heart disease and dyslipidemia, and the interaction test between groups was carried out.Results:Among the 1 028 geriatric physical examination cases, 580 (56.4%) were males and 448 (43.6%) were females, aged (66.7±5.8) years. UHR levels were higher in the hypertensive group compared to the non-hypertensive group [248.88 (191.19, 322.25) vs 213.52 (165.94, 275.29); Z=-5.445, P<0.05]. With the increase of UHR level, the detection rate of hypertension in the elderly population increased (accounted for 27.8%, 38.2% and 47.8%, respectively; χ2=29.211, P<0.05). Spearman rank correlation analysis showed that UHR was positively correlated with body mass index, triglycerides, serum uric acid, serum creatinine and fasting blood glucose ( r=0.318, 0.334, 0.774, 0.474, 0.080; all P<0.05), and negatively correlated with total cholesterol, glomerular filtration rate and low-density lipoprotein cholesterol ( r=-0.239, -0.303, -0.154; all P<0.05). When the confounding factors were not adjusted (model 1), the risk of hypertension in high UHR group was 2.382 times higher than that in low UHR group and 1.607 times higher than that in medium UHR group; after adjusting for all confounding factors such as age, gender, body mass index, systolic blood pressure, diastolic blood pressure, junior high school education or below, smoking, alcohol consumption, glomerular filtration rate, etc., the risk of hypertension in the high-level UHR group was 1.732 times higher than that in the low-level UHR group (95% CI: 1.139-2.635) ( P<0.05). The elderly physical examination population was further stratified according to whether there was diabetes, dyslipidemia and coronary heart disease, and it was found that there was no interaction between UHR and diabetes, dyslipidemia and coronary heart disease on the prevalence of hypertension (all P>0.05). Conclusions:Hypertension detection rate increases with higher UHR levels. UHR is closely related to the incidence of hypertension in the elderly population.
