Objective To analyze the disease burden and trends of bladder cancer in China and globally from 1992 to 2021.  Methods Using the GBD 2021 database, the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) rates of bladder cancer in China and globally from 1992–2021 were analyzed. Average annual percentage change (AAPC) was calculated using Joinpoint regression. Subgroup analyses by sex and age were conducted, and a Bayesian age-period-cohort (BAPC) model was used to predict trends in age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) for the next 15 years.  Results In 2021, China reported 106 000 new cases (ASIR: 5.14/100 000), 571 000 prevalent cases (age-standardized prevalence rate, ASPR: 26.61/100 000), 43 000 deaths (ASMR: 2.34/100 000), and a DALY rate of 45.31/100 000. From 1992–2021, China showed upward trends in ASIR and ASPR but declines in ASMR and DALYs, while global ASIR, ASMR, and DALYs decreased overall with slow ASPR growth. The peak cases in China and globally were both concentrated in the 65-79 age group, with a significantly higher burden on males than females. In China, smoking-related ASMR and ASDR exceeded global averages and rose, whereas high glucose-related indexes were lower and declined. Projections for 2021–2036 indicated that the global incidence and mortality rates would be rising, but ASIR/ASPR would be declining, while in China, the incidence rate would continue to rise, and the mortality rate will stabilize, with a significant increase in ASIR and a gradual decrease in ASPR.  Conclusion From 1992 to 2021, the incidence of bladder cancer in China has shown a continuous upward trend and is projected to persist in the future, with significant gender and age differences. Particular attention should be given to elderly males aged 85-89. The disease burden of bladder cancer attributable to smoking continues to rise, highlighting the urgent need to strengthen tobacco control policies.

ObjectiveTo explore the changes in volatile components， total polysaccharides， enzyme activity， and chromaticity value of Myristicae Semen Koji（MSK） during the fermentation process， and conduct correlation analysis. MethodsBased on gas chromatography-mass spectrometry（GC-MS）， the changes of volatile components in MSK at different fermentation times were identified. The phenol sulfuric acid method， dinitrosalicylic acid method（DNS）， and carboxymethyl cellulose sodium salt method（CMC-Na） were used to investigate the total polysaccharide content， amylase activity， and cellulase activity during the fermentation process. Visual analysis technology was used to explore the changes in chromaticity values， revealing the fermentation process of MSK and the dynamic changes of various measurement indicators， partial least squares-discriminant analysis（PLS-DA） was used to explore the differential compounds of MSK at different fermentation degrees， and Pearson correlation analysis was used to explore the correlation between volatile components of MSK and total polysaccharides， enzyme activity， and chromaticity values. ResultsA total of 60 volatile compounds were identified from MSK， the relative contents of components such as （+）-α-pinene， β-phellandrene， β-pinene， （+）-limonene， and p-cymene obviously increased， while the relative contents of components such as safrole， methyl isoeugenol， methyleugenol， myristicin， and elemicin significantly decreased. During the fermentation process， the total polysaccharide content showed an upward trend， while the activities of amylase and cellulase showed an initial increase followed by a decrease， and reached their maximum value at 40 h. the overall brightness（L^*） and total color difference（ΔE^*） gradually increased， while the changes in red-green value（a^*） and yellow-blue value（b^*） were not obvious. PLS-DA results showed that MSK could be clearly distinguished at different fermentation times， and 13 differential biomarkers were screened out. Pearson correlation analysis results showed that the contents of α-terpinene， β-phellandrene， methyleugenol， β-cubebene and myristic acid had an obvious correlation with chromaticity values. ConclusionAfter fermentation， the volatile components， total polysaccharides， amylase activity， and cellulase activity of MSK undergo significant changes， and there is a clear correlation between them and chromaticity values， which reveals the dynamic changes in the fermentation process and related indicators of MSK， laying a foundation for the quality control.

Objective To investigate the therapeutic efficacy of the combination of upper limb rehabilitation robots(ULRR)and ultrasound-guided extracorporeal shock wave(ESW)in the treatment of mild to moderate rotator cuff injuries.Methods A total of 90 patients with mild to moderate rotator cuff injuries,who were admitted to the Second Affiliated Hospital of Anhui Medical University between January 2023 and March 2024,were selected and randomly assigned to three groups:Group A(basic rehabilitation),Group B(basic rehabilitation+ESW),and Group C(basic rehabilitation+ESW+ULRR),with 30 patients in each group.Before and after treatment,shoulder pain was assessed using the visual analogue scale(VAS).Proprioception was evaluated based on shoulder joint position reproduction error.The integral electromyography(iEMG)and root mean square(RMS)values of the median tract,supraspinatus,infraspinatus,and deltoid muscles on the affected side were measured using surface electromyography(sEMG).The active range of motion(AROM)for external rotation,abduction,and forward flexion of the affected shoulder was measured using a standard goniometer.Overall shoulder function was evaluated using the Constant-Murley Shoulder Score(CMS).The clinical efficacy rate and patient satisfaction levels were compared among the three groups.Results After treatment,the VAS score and shoulder position reproduction deviation angle in all three groups significantly decreased.Additionally,the iEMG and RMS values of the middle deltoid,supraspinatus,and infraspinatus muscles;the AROM of shoulder external rotation,abduction,and forward flexion;and the CMS scores(including pain,activities of daily living,active range of motion,and muscle strength)all showed significant improvement.Furthermore,the degree of improvement in all evaluated parameters in Group C was significantly greater than that observed in Groups A and B(P<0.05).Moreover,Group C demon-strated a significantly higher clinical response rate and greater patient satisfaction compared to Groups A and B(P<0.05).Conclusion For patients with mild to moderate rotator cuff injuries,the integration of an upper limb rehabilitation robot with extracorporeal shock wave therapy demonstrates superior therapeutic outcomes,effectively alleviating pain,enhancing motor function and proprioception,and increasing overall patient satisfaction.

Objective Utilizing patient journey mapping to decipher disease management behaviors,barriers,and needs in young and middle-aged liver transplant recipients,providing implications for self-management optimization and quality of life improvement.Methods Using purposive sampling,12 young and middle-aged liver transplant patients who attended outpatient clinics or were hospitalized in liver transplant center of a tertiary hospital in Qingdao were selected for semi-structured interviews from September to November 2024.Thematic extraction and analysis were performed using Colaizzi's 7-step analysis,ultimately resulting in the development of a patient journey map.Results The journey stages were divided into transplantation decision-making period,transplantation waiting period,perioperative period,and post-discharge management period,and the journey key elements were designed as behaviors,barriers,and needs.A total of 25 themes were extracted,including behaviors(such as referrals to higher-level hospitals,verification of treatment options),barriers(such as lack of decision-making autonomy,health information-seeking barriers),and needs(such as shared decision-making,financial assistance).Ultimately,resulting in a map of the disease management journey for young and middle-aged liver transplant recipients.Conclusion The behaviors,barriers,and needs in disease management among young and middle-aged liver transplant recipients demonstrate distinct phase-specific patterns.Healthcare providers should deliver precise and dynamic interventions tailored to each clinical phase,aiming to foster optimal self-management behaviors,address phase-specific banriers,and meet evolving patient needs throughout the transplant continuum.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective:To investigate, for multi-sensitized allergic rhinitis (AR) patients allergic to dust mites combined with other allergens (pollen, mold, animal dander, etc.), whether the single dust mite subcutaneous immunotherapy (SCIT) can improve the specific symptoms caused by other allergens in the patients, and to analyze the relationship between the effectiveness of symptom improvement in these patients and the type, quantity and severity of the allergens.Methods:A multicenter retrospective study was conducted to collect mul-sensitized AR patients from allergy or respiratory departments of 5 hospitals who received house dust mite allergen preparation SCIT for 12 to 36 months and met other inclusion and exclusion criteria from February to July 2024. General clinical data were collected and the perennial or seasonal symptoms before and after treatment were evaluated with visual analogue scale (VAS) to assess whether there was an perennial or allergen-specific symptom improvement (VAS score decrease ≥30%), by which the patients were divided into effective group and ineffective. R software was used to analyze the differences between groups by using Fisher′s exact test and Mann-Whitney U test. Results:A total of 62 patients were enrolled, and the treatment were effective in 39 of them, with an effective rate of 62.9%. For allergen-specific symptoms, the median age of the effective group was higher than that of the ineffective group (12 years old vs. 8 years old, P=0.039), and the effective rate in dust mite specific immunoglobin E (sIgE) grade ≤5 group was higher than that in sIgE grade >5 group (81.6% vs. 45.5%, P=0.008), and the effective rate of mold sIgE grade ≤2 group was higher than that of sIgE grade >2 group (83.3% vs. 28.6%, P=0.045), and there was no statistically significant correlation between the other allergen grades and the effective rate ( P>0.05). For perennial symptoms, the effective rate in the mold grade ≤2 group was higher than that in the sIgE grade >2 group (91.3% vs. 28.6%, P=0.010), and there was no statistically significant correlation between the other allergen grades and the effective rate ( P>0.05). There was no significant correlation between the treatment effectiveness of perennial or allergen-specific symptoms and the number of combined allergens, the grade of skin test, and the difference between the grade of combined allergens and that of dust mites ( P>0.05). Conclusion:Among the patients with multi-sensitized AR allergic to dust mites included in this study, single dust mite SCIT is effective in some of them, and for allergen-specific symptoms, the effective group was elder, and dust mite sIgE grade 6 and mold sIgE grade ≥2 was related to the low effective rate of SCIT. The present results are insufficient for selecting single or multiple AIT in any type of multi-sensitized patients.

Objectives:To explore the clinical efficacy and the postoperative recurrence rate of the vertebral"Collapse"lesion resection for treating thoracolumbar spinal metastases compared to separation surgery.Methods:A retrospective study was conducted on 78 patients with thoracolumbar spinal metastases treated at Tianjin University General Hospital from December 2018 to December 2022.There were 42 males(53.8％)and 36 females(46.2％),with a mean age of 61.9±10.6 years(range 34-76 years).The patients were divided into separation surgery group(21 cases)and"Collapse"resection group(57 cases).Two to three weeks after surgery,radiotherapy,chemotherapy or targeted drugs were given according to the type of primary tumor after wound healing.The data on operative time,intraoperative blood loss,drainage volume,Frankel classification for spinal cord injury,and visual analogue scale(VAS)scores for pain preoperatively,7d after operation and at final follow-up,as well as local recurrence rates and perioperative complications were collected.Results:The operative time and intraoperative blood loss in the"Collapse"resection group(328.7±89.2min,782.5±89.2mL)were significantly higher than those in the separation surgery group(243.2±89.2min,585.7±89.2mL)(P＜0.05).There was no statistically significant difference in postoperative drainage volume between the two groups("Collapse"resection group 698.2±230.2mL vs separation surgery group 674.7±180.7mL)(P＞0.05).During follow-up,all the patients in the separation surgery group received stereotactic radiotherapy postoperatively;While 10 patients(21.2％)in the"Collapse"resection group underwent radiotherapy,and the remaining 47(78.8％)patients received targeted,immunological,or chemotherapy as part of comprehensive treatment.The recurrence rate in the separation surgery group was approximately 9.5％(2/21).Among the patients who received"Collapse"resection plus radiotherapy,there was 1 local recurrence,resulting in a recurrence rate of 10％(1/10),while the patients who didn't receive radiotherapy experienced 3 local recurrences,with a recurrence rate of 6.4％(3/47).The overall recurrence rate for patients in the"Collapse"resection group was 7.0％(4/57).There was no statistically significant difference in recurrence rates between the two surgical procedures(P=0.708).In the separation surgery group,postoperative complications included one case of wound infection,one case of wound dehiscence two months after postoperative radiotherapy,and one case of epidural hematoma causing compression.In the group of"Collapse"resection,complications included one case of cerebrospinal fluid leakage with secondary infection and one case of superficial wound infection.VAS scores on 7d postoperatively significantly decreased compared to preoperative scores in both groups(P＜0.05),and there were significant differences in VAS scores at final follow-up compared to preoperative scores(P＜0.05).No statistical difference in VAS scores was observed between the two groups on 7d postoperatively and at final follow-up(P＞0.05).Except for 5 Frankel A-D grade patients with no significant improvement in neurological function,the remaining 73 patients showed no deterioration in neurological function,with varying degrees of recovery of at least 1 grade,yielding an improvement rate of 93.6％(73/78).Conclusions:The vertebral"Collapse"resection for thoracolumbar spinal tumors does not require postoperative radiotherapy,as the tumor recurrence rate is comparable to that of patients treated with separation surgery followed by radiotherapy.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.
