Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

Objective This study aims at establishing a teaching catalog and content for breast rare dis-eases and developing the syllabus for the breast rare disease using integrated multimodality of case-/problem-/resource-based learning(CBL+PBL+RBL).Methods By conducting bibliometrics co-occurrence analysis,we collected 6291 articles on breast rare disease published from January,1975 to June,2024.Additionally,we re-trieved the Textbook on Rare Diseases,the Catalog of Chinese Rare Disease,and Second Batch of Rare Dis-ease Catalog and then decided the teaching content.Results From 16,387 keywords,1000(6.1％)keywords were identified through co-occurrence analysis,including 50(0.3％)candidate diseases.These were classified into three categories:rare primary breast diseases,rare genetic mutation-related diseases associated with breast cancer,and rare systemic multi-system diseases involving the breast.From the candidate list,20(0.1％)rare primary breast diseases were further selected for their notable clinical teaching significance,and significant multi-systemic diseases affecting the breast,whether related to gene mutations or not.Teaching plans were draf-ted using a diversified parallel teaching approaches,taking into account the characteristics of different diseases and the focus of different teaching methods.Conclusions This study initiated the development of the teaching content for breast rare diseases and developed the teaching syllabus using the CBL+PBL+RBL integrated multi teaching model and targeting each rare breast disease for the critical point for teaching.

Three-dimensional graphene hydrogel(3DGH)was successfully prepared through a hydrothermal method,followed by its composition with gold nanoparticles(AuNPs)to construct a highly sensitive Au/3DGH graphene electrochemical transistor(GECT)dopamine(DA)sensor.AuNPs are efficient electrocatalytic materials.However,their tendency to aggregate during electrodeposition hinds the practical application.The porous and interconnected network structure of 3DGH provided abundant attachment sites,effectively preventing AuNPs aggregation.By modifying the sensor's gate with Au/3DGH,the excellent electrocatalytic performance of Au/3DGH towards DA and the high sensitivity of GECT were utilized to achieve highly sensitive detection of DA.The sensor exhibited a low detection limit of 20 nmol/L and a linear range of 20 nmol/L to 2.5 mmol/L.Remarkably,the sensor showed high sensitivity,excellent selectivity and strong stability,and hold great potnetial in highly sensitive portable detection of DA in disease prevention and clinical monitoring.

This study analyzed the epidemic characteristics and spatial and temporal clustering of leptospirosis in Wenzhou from 2014 to 2023,to provide a scientific basis for prevention and control.Data for leptospirosis cases reported in Wenzhou from 2014 to 2023 were collected.Descriptive epidemiological approaches were used to analyze the cases'prevalence character-istics.Spatial autocorrelation analysis was performed in ArcGIS 10.2 software,and spatiotemporal clusters were scanned with SaTScan 10.1 software.From 2014 to 2023,189 leptospirosis cases were reported in Wenzhou,and the average annual inci-dence rate was 0.23/100 000.Relatively fewer cases occurred in 2014-2018,whereas significantly more cases occurred after 2019,and the largest number of reported cases was reported in 2021(62 cases).The peak incidence was from August to Octo-ber,accounting for 88.36％of the total incidence.The cases were mainly in males,and the sex ratio was 5.30∶1 male:female.Moreover,the cases were mainly in people in their 60s,accounting for 59.26％of total cases,and in people who were farmers,accounting for 72.49％of total cases.Global spatial autocorrelation analysis indicated that cases were randomly distributed from 2014 to 2018,and the incidence showed spatial clustering from 2019 to 2023(Moran's I＞0,P＜0.05).Local spatial autocor-relation and spatiotemporal scanning analysis revealed that leptospirosis cases were concentrated primarily in northern hilly areas of Yongjia County and other inland areas rich in vegetation from 2019 to 2023.In the past 5 years,the number of lepto-spirosis cases in Wenzhou increased,and the incidence of leptospirosis showed clear seasonal and spatial clustering.Cases were mainly in middle-aged and older farmers.Recommendations in-clude expanding the monitoring scope of leptospirosis,and per-forming prevention and control measures such as health education for key groups in key areas before the high-incidence season.

Aim To investigate the protective effects of co-administered piperine on reversing the skeletal deterioration induced by fluoxetine.Methods Female ovariectomized rats were orally administered with estra-diol,fluoxetine,piperine and the mixture of piperine and fluoxetine for eight weeks,respectively.X-ray ab-sorption assay was used to determine bone mineral den-sity(BMD).microCT was used to analyze the effects of drug treatments on micro-architecture,three-bending test was performed to examine the biomechanical prop-erties.ELISA kits were employed to quantify the bone turnover markers in serum.Besides,rat primary osteo-blasts were cultured to investigate the osteoblastogene-sis and mineralization in the presence of fluoxetine with or without piperine.Results Compared with ovariec-tomized rats,the administration of estradiol and piper-ine significantly enhanced BMD and biomechanical properties with improved micro-architecture of trabecu-lar bones.Fluoxetine treatment further deteriorated BMD,biomechanical properties and micro-architecture of ovariectomized rats with accelerated bone turnover.Concomitant administration of piperine with fluoxetine significantly suppressed the deteriorating effects on skeleton by fluoxetine.In addition,fluoxetine reduced the differentiation and mineralization of primary osteo-blasts,whereas combined therapy showed promotional effects.Conclusions The administration of fluoxetine induces further bone loss in ovariectomized rats by in-hibiting osteoblastic differentiation and mineralization.The co-administration of piperine with fluoxetine rever-ses its skeletal deterioration.

To summarize the clinical diagnosis and treatment process and genetic test results and characteristics of one child with Angelman syndrome (AS) complicated with oculocutaneous albinism type 2 (OCA2), and to review the literature. "Angelman syndrome" "P gene" and "Oculocutaneous albinism type 2" were used as keywords to search at CNKI, Wanfang, and PubMed databases (from creation to December 2019). Then all the patients were analyzed. The patient in this study was a girl aged 1 year. After birth, she was found to present as white body, yellow hair, and nystagmus. She could raise her head at the age of 2 months and turn over at the age of 7 months. The head circumference was 42 cm and she could not sit alone or speak at present. Trio-based exome sequencing revealed that the patient carried a homozygous mutation of c.168del (p.Gln58ArgfsTer44) in the P gene, and her father was heterozygous and her mother was wild-type. The detection of copy number variation showed deletion on the maternal chromosome at 15q11.2-13.1 region (P gene located in this region) in the patient. Until December 2019, a total of 4 cases in the 4 literature had been reported. Adding our case here, the 5 cases were summarized and found that all the cases showed white skin, golden hair, and shallow iris after birth. Comprehensive developmental delay was found around 6 months of age after birth, and the language remained undeveloped in 2 cases till follow-up into childhood. Seizures occurred in 4 patients. Two cases had ataxia. All the 5 cases had acquired microcephaly. Two cases had a family history of albinism. Electroencephalogram monitoring was completed in 3 cases and the results were abnormal. Genetic tests showed that all the 5 cases had deletion on maternal chromosome at 15q11-13 region. Four cases carried mutation of P gene on paternal chromosome. And 1 case was clinically diagnosed as OCA2 without P gene test. AS combined with OCA2 is relatively rare. OCA2 is easily diagnosed based on the obvious clinical manifestations after birth. When combined with clinical manifestations such as neurodevelopmental delay, it might indicate the possibility of AS that is hardly diagnosed clinically at an early stage. Genetic tests can reveal the cross-genetic phenomenon of AS and OCA2 and the complex of them can be eventually diagnosed.
