Chinese Journal of School Health 2026;47(5):656-660
Objective:
To explore the association of three types of built environment (housing, school and the school commute route) with mental health of junior and senior high school students under different intensities of exercise activities, so as to provide reference for improving the mental health of junior and senior high school students.
Methods:
From September to October 2024, 476 junior and senior high school students from 11 residential communities were selected in Hefei City to conduct household questionnaire survey. The survey content included subjective perception of the surrounding environment, exercise characteristics, anxiety, depression and hostility. Structural equation model was used to analyze the relationship of environment perception and exercise characteristics with mental health of junior and senior high school students.
Results:
About 41.81% of the surveyed junior and senior high school students had mental health issues. Path analysis results indicated that residential environment ( β = 0.41 ) and school route environment ( β =0.24) directly affected the mental health of junior and senior high school students; commercial and service facilities around the residence ( β =-0.36), transportation convenience ( β =-0.43), pedestrian friendly roads ( β =-0.45), the sense of safety when alone ( β =-0.58), and the sense of safety in the school commute route environment ( β =-0.17) could directly reduce the severity of psychological issues among junior and senior high school students(all P <0.05). Conversely, traffic congestion ( β =0.66), noise pollution ( β =0.80), and air pollution ( β =0.57) on the school commute route significantly increased the risk of psychological problems(all P <0.05). School surroundings ( β =0.24) indirectly affected mental health through built environment ( β = 0.83) and exercise characteristics ( β =0.23), with only increased frequency ( β =-0.22) and duration ( β =-0.19) of high intensity activities showing positive effects on mental health (all P <0.05).
Conclusions
The mental health status of junior and senior high school students in Hefei is related to built environments and exercise intensity. It is suggested to improve the environment of residence, school and learning path in a targeted way, and guide junior and senior high school students to increase the amount of high intensity exercise activities, so as to reduce the risk of various psychological problems.

Objective:To investigate the staging criteria of renal tuberculosis,and to analyze the diagnostic and therapeutic characteristics as well as prognostic outcomes at different stages.Methods:A retrospective analysis was conducted on the clinical data of 134 patients with renal tuberculosis who were admitted to the Second Hospital of Lanzhou University between January 2019 and December 2023.The study cohort included 62 males and 72 females,with a mean age of(46.63 ± 13.52)years and a mean body mass index(BMI)of(22.85 ± 3.73)kg/m 2. A total of 107 patients resided in rural areas. Sixty patients had a history of pulmonary tuberculosis. Tuberculous lesions were located in the left kidney in 72 cases and in the right kidney in 62 cases. The main presenting complaints included irritative lower urinary tract symptoms in 85 patients and systemic symptoms in 92 patients. Ureteral involvement was observed in 97 patients,bladder involvement in 32 patients,and genital involvement in 9 patients. Based on computed tomography(CT)findings,the number,extent,and degree of renal destruction caused by tuberculous lesions were comprehensively evaluated in axial,coronal,and sagittal planes. The primary staging criteria included lesion diameter(2 cm)and the proportion of renal volume involved by the lesion(one-third,one-half,and two-thirds). Renal tuberculosis was classified into three stages and six subtypes:Stage Ⅰa,a solitary lesion with a diameter ≤ 2 cm;Stage Ⅰb,a solitary lesion >2 cm or multiple lesions confined within one-third of the renal volume;Stage Ⅱa,lesions involving more than one-third but confined within one-half of the renal volume;Stage Ⅱb,lesions involving more than one-half but confined within two-thirds of the renal volume;Stage Ⅲa,lesions involving more than two-thirds of the renal volume with a glomerular filtration rate(GFR)of the affected kidney <10 ml/min;and Stage Ⅲb,complete renal calcification,presenting as an “autonephrectomy”. Among the 134 patients included in this study,7 were classified as Stage Ⅰa,17 as Stage Ⅰb,20 as Stage Ⅱa,19 as Stage Ⅱb,62 as Stage Ⅲa,and 9 as Stage Ⅲb. The severity of hydronephrosis was graded as follows:mild,renal pelvic separation <2 cm;moderate,2-3 cm;and severe,>3 cm. Prior to treatment,the mean renal pelvic separation was(1.76 ± 0.92)cm in Stage Ⅰa,(1.69 ± 0.81)cm in Stage Ⅰb,and(1.10 ± 0.82)cm in Stage Ⅱa,corresponding to mild to moderate hydronephrosis. All 7 patients in Stage Ⅰa underwent ureteroscopic examination and double-J stent placement,combined with a 6-month short-course anti-tuberculosis regimen consisting of isoniazid,rifampicin,pyrazinamide,and ethambutol for 2 months(intensive phase),followed by isoniazid and rifampicin for 4 months(continuation phase). Among the 17 patients in Stage Ⅰb,13 presented with hydronephrosis and underwent ureteroscopic examination and double-J stent placement in combination with 6 months of anti-tuberculosis therapy,while 4 patients with isolated renal tuberculosis received anti-tuberculosis therapy alone for 6 months.Of the 20 patients in Stage Ⅱa,4 with hydronephrosis underwent ureteroscopic examination and double-J stent placement plus 6 months of anti-tuberculosis therapy,whereas 16 underwent nephroureterectomy. All 19 patients in Stage Ⅱb underwent nephroureterectomy. Among the 62 patients in Stage Ⅲa,60 underwent nephroureterectomy,while 2 refused surgery and were treated with the 6-month short-course anti-tuberculosis regimen. Of the 9 patients in Stage Ⅲb,8 underwent nephroureterectomy;in 1 patient,surgery was not performed due to severe adhesions in the operative field,and the patient received the 6-month short-course anti-tuberculosis regimen instead. Follow-up assessments included clinical symptoms,erythrocyte sedimentation rate(ESR),serum creatinine,degree of renal pelvic separation,and imaging findings from urinary tract CT. Efficacy was evaluated according to the following criteria:Cure was defined as clinical stability with all of the following conditions:① improvement of systemic symptoms,including absence of flank pain,fever,and lower urinary tract irritative symptoms,with normalization of erythrocyte sedimentation rate(ESR);② negative urine culture for Mycobacterium tuberculosis;and ③ complete calcification of renal lesions and/or no evidence of tuberculous lesions at other sites. Stable disease was defined as no change in the size or extent of renal tuberculosis lesions. Progressive disease was defined as enlargement or increase in the number of tuberculous lesions or involvement of additional sites. Results:Among the 7 patients in Stage Ⅰa,follow-up imaging after treatment showed a mean renal pelvic separation of(0.44 ± 0.56)cm,which was significantly reduced compared with baseline( t = 3.909, P = 0.008). Five patients achieved cure,1 remained stable,and 1 showed disease progression and subsequently underwent nephroureterectomy,resulting in postoperative cure. In Stage Ⅰb,among 13 patients with hydronephrosis,post-treatment imaging showed a mean renal pelvic separation of(0.8 ± 0.75)cm,a statistically significant improvement from baseline( t = 5.633, P < 0.01). Six patients were cured,4 remained stable,and 3 experienced disease progression and underwent nephroureterectomy. Of the 4 patients with isolated renal tuberculosis,2 were controlled,and 2 progressed and underwent nephroureterectomy. In Stage Ⅱa,among 4 patients with tuberculous hydronephrosis,post-treatment renal pelvic separation was(1.20±0.98)cm,with no significant difference from baseline( t = -1.675, P = 0.193);these patients underwent nephroureterectomy 1-2 years later. The remaining 16 patients without hydronephrosis underwent nephroureterectomy and were cured. All 19 patients in Stage Ⅱb underwent nephroureterectomy;17 were cured,and 2 developed ipsilateral perirenal fluid collections 3 months postoperatively,which resolved spontaneously with the standard 6-month anti-tuberculosis regimen. Among 62 patients in Stage Ⅲa,60 underwent nephroureterectomy. Of these,54 were cured;1 developed a urinary tract infection within 2 weeks postoperatively;3 showed contralateral renal disease progression at 3 months;and 1 developed ipsilateral perirenal fluid at 3 months,which resolved spontaneously with standard anti-tuberculosis therapy. One patient developed solitary kidney failure 7 months postoperatively and underwent ureteral stent placement,with disease remaining stable thereafter. Two patients refused surgery and received only anti-tuberculosis therapy;during follow-up,1 patient experienced disease progression and died of disseminated tuberculosis after 1 year,while the other developed contralateral renal involvement at 3 months and received standard 6-month therapy,with disease remaining stable. Among 9 patients in Stage Ⅲb,8 underwent nephroureterectomy and were cured. One patient,with severe adhesions precluding surgery,received anti-tuberculosis therapy alone,and disease remained stable over a 2-year follow-up. Conclusions:The CT-based staging system for renal tuberculosis proposed in this study(three stages and six subtypes)effectively reflects the severity of renal lesions and clearly delineates the clinical characteristics and prognostic outcomes at each stage. Stage Ⅰ patients treated with anti-tuberculosis drugs combined with double-J stent placement demonstrated favorable outcomes and high renal preservation rates. In contrast,Stages Ⅱ and Ⅲ patients showed poor responses to anti-tuberculosis therapy combined with drainage,with a higher risk of disease progression and relatively worse prognosis,highlighting the recommendation for early nephroureterectomy of the affected kidney.

Objective To propose a frequency-domain pulse wave prediction model based on fusion attention mechanism,improving the low classification accuracy and poor generalization performance of hypertension time-domain pulse wave classification based on artificial intelligence technology.Methods Firstly,the time-domain pulse wave was transformed into frequency-domain Mel-scale frequency cepstral coefficient features to enhance its discriminability.Then,temporal convolutional network and Transformer structures were employed to extract the deep features of pulse waves,and self-attention mechanism and selective kernel attention were combined for decision fusion to extract relevant features.Floodings regularization method was used to indirectly control the training loss and prevent overfitting.A 5-fold cross-verification experiment was conducted based on 527 clinical pulse diagnosis data provided by Longhua Hospital,Shanghai University of Traditional Chinese Medicine and Shanghai Traditional Chinese Medicine-Integrated Hospital.Additionally,the extreme gradient boosting algorithm was employed to calculate the contribution rate ranking of frequency-domain pulse wave features,and the key factors affecting the classification accuracy of the model were analyzed to provide reference for the clinical auxiliary diagnosis of traditional Chinese medicine.Results The evaluation metrics accuracy,F1 score,precision,recall rate and area under curve value of the model proposed in this study were 0.939 6,0.924 9,0.940 9,0.929 5,and 0.993 4,respectively.The static characteristics of the pulse wave,the contribution rate of the first-order difference and the second-order difference coefficients were relatively balanced,indicating that the degree of hypertension risk was not only related to the static characteristics of the pulse wave,but also to the dynamic characteristics of the pulse wave.Conclusion The proposed model has higher classification accuracy and generalization performance compared to typical pulse wave classification models.
