Objective: To investigate the association between the physical fitness index (PFI) and symptoms of depressive, anxiety and stress symptoms among college students, providing a reference for mental health interventions. Methods: From June to September 2025, combined convenience and cluster random sampling approach was used to administer questionnaire surveys and perform physical fitness tests on 2 712 college students from Zhejiang Chinese Medical University. The Depression Anxiety Stress Scales-21 Items (DASS-21) was used to assess mental health status. Chi square test and multivariate Logistic regression analysis were used to determine the associations between the PFI and the PFI component indicators with depressive, anxiety and stress symptoms. Results: The prevalence of depressive, anxiety and stress among college students were 24.26%, 33.22% and 13.68%, respectively. Statistically significant differences in the prevalence of these symptoms were detected across groups differing in sleep quality, physical activity, weekly breakfast frequency, and history of low back or neck pain ( χ 2=9.33-151.83, all P <0.05). After adjusting for confounding factors, Logistic regression revealed that the moderate and high PFI groups had significantly reduced risks of depressive and anxiety compared to the low PFI group ( OR =0.73, 0.63; 0.61, 0.72, all P <0.05). Poor speed (50 m run) and lower body strength (standing long jump) emerged as common risk factors affecting anxiety and depressive symptoms in both male and female college students (all P <0.05). Increased muscle strength (sit up for 1 min) in female students reduced the risk of depressive ( OR =0.81), anxiety ( OR =0.85), and stress symptoms ( OR =0.79) (all P <0.05). Enhanced lung capacity in male students decreased the risk of depressive ( OR =0.84) and anxiety symptoms ( OR =0.85) (both P <0.05). Conclusions The PFI is negatively correlated with depressive and anxiety symptoms among college students with notable gender differences. Insufficient speed and lower body explosive power represent common risk factors for mental health among male and female college students.

Objective:To retrospectively evaluate the clinical efficacy and safety of total 3D laparo-scopic ileal ureters replacement for bilateral ureters combined with bladder augmentation in patients with post-radiotherapy long-segment bilateral ureteral strictures and contracted bladder.Methods:Clinical data of two patients(aged 72 and 54 years)with radiation-induced long-segment bilateral ureteral stric-tures and reduced bladder capacity,treated at the Sixth Affiliated Hospital of Jinan University from Octo-ber 2023 to June 2024,were analyzed.Both presented with bilateral flank pain,recurrent chills/fever,urinary frequency,and urgency.Preoperative ureteral stricture lengths were measured as follows:left 10.4 cm and right 8.7 cm in the first case;left 10.6 cm and right 11.7 cm in the second case.Bladder capacity assessed by nephrostomy-assisted antegrade urography was 90 mL and 130 mL respectively.Both underwent single-position,one-stage totally 3D laparoscopic bilateral ileal ureteral replacement and blad-der augmentation based on membrane anatomy principles,with regular postoperative follow-up.Results:Procedures were completed by the same experienced urologist.Operative times were 420 min and 355 min,with intraoperative blood loss of 50 mL(no transfusion required).Postoperative bowel function re-sumed at the end of 4.5 and 3 days.No major perioperative complications occurred.Ureteral stents were removed at 2 months postoperatively,with imaging showing improved hydronephrosis,unobstructed ure-teral drainage,symmetrical bladder morphology,and smooth walls.Postoperative bladder capacities were 230 mL and 250 mL.Follow-up durations were 10 and 8 months.Both patients experienced significant relief of flank pain and lower urinary tract symptoms.No complications(enteric fistula,urinary fistula,or metabolic acidosis)were observed.At the final follow-up,one patient had mildly elevated serum cre-atinine,while the other showed reduced levels compared with preoperative values;both remained stable.Conclusion:Membrane anatomy-based dissection facilitates safe mobilization of fibrotic ureters with mini-mal bleeding and collateral damage.Total intracorporeal 3D laparoscopic ileal ureters replacement for bi-lateral ureters combined with bladder augmentation effectively addresses long-segment ureteral obstruction and improves bladder capacity.This approach is technically safe and feasible,though further validation with larger clinical cohorts is warranted.

Objective To explore the clinical value of laparoscopic radical cystectomy based on fascia anatomy for bladder cancer treatment.Methods The clinical data of 51 patients with bladder cancer who underwent 3D laparoscopic radical cystectomy during Jan.2015 and Jun.2022 were retrospectively analyzed.The surgery was performed based on membrane anatomy technology along four longitudinal and two transverse planes to complete the radical cystectomy.The pelvic plexus was preserved for patients with normal preoperative sexual function.Results All surgeries were completed without conversion to open operation.The mean operation time was(502.52±108.99)min,mean intraoperative blood loss was(275.96±155.18)mL,mean postoperative drainage time was(4.14±2.41)d,and the mean postoperative hospital stay was(16.37±4.85)d.The mean number of lymph nodes removed was(17.98±11.48).The mean postoperative follow-up was(30.27±19.39)months.At the last follow-up,no Clavien ≥grade 3 complications were observed.The estimated overall survival(OS),tumor-specific survival(TSS),and recurrence-free survival(RFS)were 82.4％,92.2％,and 88.2％,respectively.The lymph node positive patients had shorter OS and RFS(60.0％,60.0％)than the lymph node negative patients(84.8％,91.3％).Among the 19 male patients who underwent radical cystectomy with pre-exposure and preservation of pelvic plexus,daytime and nocturnal continence rate were 83.3％and 72.2％,respectively,and 17 patients recovered potency within 6 months postoperatively.Conclusion Laparoscopic radical cystectomy based on fascia anatomy is safe and effective in laparoscopic radical cystectomy,with standardized surgical procedure,satisfactory oncological outcomes,little hemorrhage,few complications and fast recovery.

Objective:To investigate the efficacy of a trauma-integrated treatment program for severe traumatic brain injury and its effect on patients' coagulation and neurological functions.Methods:A total of 114 patients with severe traumatic brain injury who received treatment at the Department of Trauma Surgery at the Jinhua Municipal Central Hospital from April 2020 to October 2022 were retrospectively included in this study. The patients were divided into two groups based on different treatment protocols: Group A ( n = 57 patients) received the conventional emergency treatment protocol, while Group B ( n = 57 patients) received the trauma-integrated treatment protocol. The emergency treatment efficiency (including emergency room stay time, waiting time for auxiliary examinations, waiting time for multidisciplinary consultations, and time from emergency to surgery), coagulation function (prothrombin time, thrombin time, activated partial thromboplastin time), neurological function (National Institutes of Health Stroke Scale), incidence of complications (stress ulcers, pulmonary infections, hypernatremia, and cerebral salt-wasting syndrome), and prognosis were compared between the two groups. Results:The emergency room stay time, waiting time for auxiliary examinations, waiting time for multidisciplinary consultations, and time from emergency to surgery in Group B [(21.94 ± 6.21) minutes, (5.78 ± 1.12) minutes, (10.58 ± 2.47) minutes, and (8.57 ± 2.01) minutes] were significantly shorter than those in Group A [(32.59 ± 6.83) minutes, (9.46 ± 2.57) minutes, (17.36 ± 3.71) minutes, (15.36 ± 4.49) minutes, t = 8.71, 9.91, 11.48, 10.42, all P < 0.001]. After treatment, the prothrombin time, thrombin time, and activated partial thromboplastin time in Group B [(19.78 ± 2.32) seconds, (21.16 ± 2.60) seconds, (39.35 ± 4.60) seconds] were significantly shorter than those in Group A [(21.83 ± 2.63) seconds, (23.28 ± 2.95) seconds, (42.16 ± 5.52) seconds, t = 4.41, P < 0.001, t = 4.07, P < 0.001, t = 2.95, P = 0.002]. The National Institutes of Health Stroke Scale score after treatment in Group B [(13.55 ± 3.17) points] was significantly lower than that in Group A [(18.36 ± 3.83) points, t = 7.30, P < 0.001]. The incidence of complications in Group B [7.02% (4/57)] was significantly lower than that in Group A [22.81% (13/57), χ2 = 5.60, P = 0.018]. The rate of good prognosis in Group B [66.67% (38/57)] was significantly higher than that in Group A [47.37% (27/57), χ2 = 4.33, P = 0.037]. Conclusion:The trauma-integrated treatment protocol is effective for severe traumatic brain injury, as it improves emergency treatment efficiency, enhances coagulation and neurological functions, reduces the incidence of complications, and is beneficial for prognosis.

Objective To explore the clinical features,treatment and prognosis of glioblastomas(GBM)in adults.Methods A retrospective cohort study was performed on 176 adult GBM patients admitted to our department from January 2015 to December 2021.Chi-square test was used to investigate the clinical differences between isocitrate dehydrogenase(IDH)mutant and wild-type GBM.Kaplan-Meier and Log-Rank tests were employed to plot survival curve and compute the survival analysis.Multivariate Cox regression model was applied to identify the independent prognostic factors.Results IDH wild-type GBM account for 89.2％and had significantly differences from the IDH-mutant GBM in terms of age of onset,Karnofsky(KPS)score at admission,symptoms of neurological deficit,and methylation status of O6-methylguanine-DNA-methyltransferase(MGMT)promoter(P＜0.05).For the IDH wild-type GBM patients receiving conventional therapy,univariate Cox hazard analysis showed gross total resection,methylation of MGMT promoter,initiation of radiation within the 5th to 6th week after surgery,and adjuvant temozolomide(TMZ)chemotherapy ≥6 cycles were favorable prognostic factors for overall survival(OS);GBMs in the left hemisphere,involvement of single lobe,methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery were favorable prognostic factors for progression free survival(PFS)(all P＜0.05).Moreover,multivariate Cox hazard regression analysis indicated that methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery,and adjuvant TMZ chemotherapy ≥6 cycles were independent protective factors for OS,and GBMs in the left hemisphere,involvement of single lobe and methylation of MGMT promoter were independent protective factors for PFS in the GBM patients(all P＜0.05).Conclusion The clinical and prognostic features are totally different between IDH mutant and wild-type GBM,and molecular detections are needed for the further pathological classification.Methylation of MGMT promoter is a primary marker of favorite prognosis for IDH wild-type GBM,and slightly delay in radiotherapy(the 5th to 6th week after surgery)can effectively improve the survival prognosis of IDH wild-type GBM.

Depression is a common debilitating disorder affecting over 300 million individuals worldwide, emphasizing the pressing need to develop novel treatment targets for this disorder. Nevertheless, the pathophysiology of this disorder remains incompletely elucidated, and the currently available antidepressant treatments are suboptimal in terms of their efficacy and delayed onset of action. Thus, identifying and exploring new therapeutic avenues is of paramount importance. Recent clinical and preclinical studies have demonstrated that numerous bitter taste receptor type 2 members (Tas2Rs) agonists, including epigallocatechin gallate (EGCG), resveratrol, caffeine, humulones, and berberine, can significantly alleviate depressive symptoms in both human patients and animal models of depression. However, the precise mechanisms underlying the antidepressant effects of Tas2Rs agonists remain largely unknown. Intriguingly, a growing body of evidence suggests that Tas2Rs agonists may modulate various signaling pathways and systems including neurotransmission, inflammation, brain-gut axis, and the blood-cerebrospinal fluid barrier, all of which are believed to be implicated in the pathophysiology of depression. Therefore, this review aims to provide a comprehensive overview of the potential mechanisms of Tas2Rs agonists in depression, It synthesizes current evidence regarding its involvement in neurotransmission, inflammation, brain-gut communication, blood-cerebrospinal fluid barrier function, and other relevant pathways. This review will not only provide a valuable foundation for future research on the therapeutic potential of Tas2Rs agonists for depressive disorders but also offer new insights into the understanding of the pathophysiology of depression and the development of novel treatment strategies for this disorder.

As a common psychiatric disorder, the etiology and pathogenesis of depression are complex and not yet fully elucidated.The diagnosis of depression mainly depends on the patients’ medical history, clinical symptoms and related examinations.Identification of biomarkers will provide important clues for the specific diagnosis and targeted treatment of depression.In addition to the widely recognized neurotransmitter dysregulation, hypothalamus-pituitary-adrenal axis hyperactivity, neuroplasticity, and neuro-inflammation theory, oxidative stress is also involved in the pathogenesis of depression in multiple ways.Many studies showed that the heat shock protein 70(HSP70)levels will increase in early stage to cope with the stress in patients with depression.However, lower HSP70 levels are often correlated with more severe depressive symptoms.HSP70 may be involved in depression through multiple pathways of oxidative stress, glucocorticoid receptors, neuroinflammation and neuroplasticity.Furthermore, increasing HSP70 expression results in significant improvement in depression-like behavior in animals.Thus, HSP70 possesses potential value as an early warning marker for depression as well as a therapeutic target.

Objective:To explore the feasibility and clinical efficacy of oblique lateral interbody fusion (OLIF) in the treatment of adjacent segment disease (ASDis).Methods:Retrospective analysis was conducted on the data of 31 patients with ASDis treated by OLIF in four medical centers from June 2015 to December 2018. There were 17 males and 14 females. The average age was (65.7±3.4) years (range, 59 to 75 years). 19 cases received single-segment fixed fusion, 11 cases received double-segment fixed fusion and 1 case received three-segment fixed fusion. Original fixed fusion site: 1 case of L 1, 2, 3 cases of L 3, 4, 11 cases of L 4, 5, 4 cases of L 5S 1, 6 cases of L 3-L 5, 5 cases of L 4-S 1, and 1 case of L 3-S 1. The time from the initial fixation and fusion to this admission was 82.5±45.5 months (rang, 24 to 180 months). ASDis occurred at the proximal end of the fixed fusion segment in 28 cases and at the distal end in 3 cases. The types of ASDis: degenerative disc disease in 11 cases, lumbar spinal stenosis in 15 cases, degenerative spondylolisthesis in 2 cases, and degenerative scoliosis in 3 cases. The location of ASDis: 6 cases of L 2, 3, 12 cases of L 3, 4, 6 cases of L 4, 5, 3 cases of L 1-L 3, 1 case of L 2-L 4, and 3 cases of L 1-L 4. At admission, 3 cases of lumbar internal fixation had been removed and 28 cases of internal fixation remained. Stand-alone OLIF was performed in 19 cases, OLIF combined with pedicle screw fixation in 8 cases, and OLIF combined with cortical screw fixation in 4 cases. Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate the low back pain and lumbar function before operation and at the last follow-up, and the imaging results and complications were observed. Results:All patients were followed up. The follow-up time was 23.6±9.6 months (range, 12 to 60 months). The operation time was 73.8±25.3 mins (range, 40 to 180 min), and the intraoperative blood loss was 86.2±67.4 ml (range, 20 to 310 ml). The average blood loss in each segment was 24.8 ml. During the operation, there were 1 case of segmental vein injury, 7 cases of endplate injury, 2 cases of transient iliopsoas muscle weakness, 1 case of thigh pain and numbness, and 1 case of incomplete intestinal obstruction. There was no incision necrosis and infection. The VAS score of low back pain decreased from 5.9±1.9 before operation to 1.4±0.6 at the last follow-up, with a statistically significant difference ( t=8.47, P<0.001). The ODI index recovered from 45.2%±5.7% before operation to 13.8%±4.7% at the last follow-up, with a statistically significant difference ( t=7.92, P<0.001). The height of intervertebral space increased from 8.7±1.6 mm before operation to 11.4±1.9 mm after operation and 9.9±1.8 mm at the last follow-up. There was a statistically significant difference between postoperative and preoperative height of intervertebral space ( F=4.15, P=0.007). There was a statistically significant difference between the last follow-up and postoperative height of intervertebral space ( P=0.011). During the follow-up, there were 13 cases of fusion cage subsidence, 1 case of fusion cage displacement, and no case of internal fixation loosening or fracture. The intervertebral fusion rate was 94%(29/31) and the complication rate was 42%(13/31). Conclusion:ASDis is a common complication after lumbar fixation and fusion, and requires surgical treatment. OLIF is a reliable method to treat ASDis as it has advantages of small trauma, high fusion rate and low complication rate.
