[Objective] To compare the diagnostic accuracy of three imaging modalities, inlducing CT urography (CTU), contrast-enhanced MRI (CE-MRI), and contrast-enhanced ultrasound (CEUS) in the qualitative diagnosis of renal space-occupying lesions. [Methods] A retrospective analysis was performed on 542 patients with renal lesions confirmed by surgical pathology in our hospital during Jan.2019 and May 2024.The diagnostic results of CTU, CE-MRI and CEUS were compared and analyzed based on the patients' clinical and pathological data. [Results] The diagnostic accuracy rate of CTU, CE-MRI and CEUS were 84.50%, 83.14% and 86.14%, respectively.For the 161 patients who underwent all three examinations, CEUS was significantly more accurate than CTU (84.16% vs. 77.02%, P=0.018), while there was no significant difference between CTU or CEUS and CE-MRI (79.81%) (P>0.05). Further analysis found that for lesions ≤4 cm, the accuracy of the three examinations was as follows: CEUS=CTU 79.55%, CE-MRI 76.14%, with no significant difference (P>0.05). However, for lesions >4 cm, CEUS ranked the first, followed by CE-MRI and CTU (89.73% vs. 84.25% vs. 73.97%), and CEUS and CE-MRI were better than CTU (P<0.05). Additionally, for the diagnosis of clear cell renal carcinoma and benign renal space-occupying lesions, there was no statistically significant difference among the three imaging modalities (P>0.05), while for the qualitative diagnosis of non-clear cell renal carcinoma, CEUS ranked the first, followed by CE-MRI and CTU (83.87% vs. 74.19% vs. 56.45%), and CE-MRI and CEUS were better than CTU (P<0.05). [Conclusion] All of them have important diagnostic value, and the appropriate selection should be based on patients' specifc conditions.CEUS and CE-MRI are more accurate in the qualitative diagnosis of renal space-occupying lesions than CTU, especially for large lesions and non-clear cell carcinoma.

Objective:To investigate the clinical efficacy of percutaneous kyphoplasty (PKP) assisted by intuitive visual navigation orthopaedic surgery robot in the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective analysis was conducted in Peking University Third Hospital from June 2021 to November 2022, 78 patients with OVCF were treated by the intuitive visual navigation orthopaedic surgery robot or freehand surgery with a "C" arm X-ray machine. According to the method of puncture, they were divided into robot group and freehand group. In the robot group, there were 36 cases, including 7 males and 29 females, aged 74.50±5.87 years, 32 cases of single vertebral fractures, 4 cases of double vertebral fractures, 1 case of T 8, 2 cases of T 10, 2 cases of T 11, 11 cases of T 12, 10 cases of L 1, 8 cases of L 2, 2 cases of L 3, 3 cases of L 4, and 1 case of L 5. Bone mineral density T value was -2.94±0.50; In the freehand group, there were 42 cases, including 9 males and 33 females, aged 72.86±8.84 years, 36 cases of single fracture and 6 cases of double fracture, 1 case of T 6, 2 cases of T 7, 3 cases of T 11, 9 cases of T 12, 8 cases of L 1, 9 cases of L 2, 5 cases of L 3, 6 cases of L 4, and 5 cases of L 5. Bone mineral density T value was -3.00±0.50. The effectiveness evaluation indexes of the two groups were compared, which included surgery duration, X-ray fluoroscopy times, hospitalization time, lumbar pain visual analogue scale (VAS), Oswestry disability index (ODI) and height of fractured anterior vertebrae (HFAV). Results:Both groups of patients successfully received surgical treatment. The mean operating time of the robot group was 33.44±2.50 min, which was significantly longer than that of the free hand group, which was 29.69±2.40 min ( t=6.491, P<0.001). Meanwhile, the intraoperative blood loss of the robot group was 3.54±0.89 ml, which was significantly less than that of the freehand group, which was 6.72±1.89 ml ( t=9.110, P<0.001). In terms of radiographic fluoroscopy times, the average of the robot group was 26.81±7.76 times, which was significantly less than the freehand group's 42.61±6.62 times ( t=9.294, P<0.001). The postoperative vertebral front edge height in the free hand group was 18.64±0.32 mm and in the robot group was 18.79±0.36 mm. The difference was not statistically significant ( t=2.673, P=0.067). All patients were followed up for 8.3±2.9 months (range, 6-13 months). The VAS scores of low back pain in the two groups at 1 day and 6 months after operation were significantly improved compared with those before operation ( P<0.05), and there was no significant difference between the two groups in VAS score after operation ( P>0.05). Six months after surgery, the ODI of the free hand group and the robot group were 11.67%±2.13% and 12.11%±2.33%, respectively. The ODI scores of the two groups were significantly lower at 6 months postoperative follow-up than that before surgery, and the postoperative follow-up at all had significant differences compared with that before surgery ( P<0.05), and there was no difference between the two groups in postoperative ODI scores ( P>0.05). No obvious bone cement leakage was found in all patients during operation. Conclusion:Compared with the traditional C-arm X-ray for PKP treatment of OVCF by free hand, intuitive visual navigation orthopedic robot can safely and effectively assist in the completion of the operation process, and has the advantages of less intraoperative blood loss, fewer fluoroscopy times.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

Multiple plant lineages have independently evolved sex chromosomes and variable kary-otypes to maintain their sessile lifestyles through constant biological innovation.Morus notabilis,a dioecious mulberry species,has the fewest chromosomes among Morus spp.,but the genetic basis of sex determination and karyotype evolution in this species has not been identified.In this study,three high-quality genome assemblies were generated for Morus spp.[including dioecious M.notabilis(male and female)and Morus yunnanensis(female)]with genome sizes of 301-329 Mb and were grouped into six pseudochromosomes.Using a combination of genomic approaches,we found that the putative ancestral karyotype of Morus species was close to 14 protochromosomes,and that sev-eral chromosome fusion events resulted in descending dysploidy(2n=2x=12).We also charac-terized a~6.2-Mb sex-determining region on chromosome 3.Four potential male-specific genes,a partially duplicated DNA helicase gene(named MSDH)and three Ty3_Gypsy long terminal repeat retrotransposons(named MSTG1/2/3),were identified in the Y-linked area and considered to be strong candidate genes for sex determination or differentiation.Population genomic analysis showed that Guangdong accessions in China were genetically similar to Japanese accessions of mul-berry.In addition,genomic areas containing selective sweeps that distinguish domesticated mul-berry from wild populations in terms of flowering and disease resistance were identified.Our study provides an important genetic resource for sex identification research and molecular breeding in mulberry.

ObjectiveTo explore the predictive role of the degree of prospective memory impairment on the treatment response to Selective Serotonin Reuptake Inhibitors (SSRIs) in patients with obsessive-compulsive disorder. MethodsA total of 30 patients with obsessive-compulsive disorder who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) were selected, and all patients were treated with SSRIs for 4 weeks. The severity of obsessive-compulsive symptom was assessed using Yale-Brown Obsessive Compulsive Scale (Y-BOCS), and the efficacy was evaluated by the reduction rate of Y-BOCS score. Moreover, the performance of event-based, time-based and activity-based prospective memory tasks were compared before and after treatment. ResultsAfter treatment, the total Y-BOCS score of patients was lower than before treatment [(27.07±4.63) vs. (24.87±5.93), F(1,29)=4.984, P=0.033], meantime, the performance of event- and time- based prospective memory tasks was improved [(0.78±0.21) vs. (0.88±0.11), F(1,29)=9.022, P=0.005; (0.81±0.17) vs. (0.91±0.11), F(1,29)=9.063, P=0.005]. Correlation analysis showed that the performance of event-based prospective memory at baseline was positively correlated with the reduction of Y-BOCS score (r=0.478, P=0.014). The event-based prospective memory performance at baseline could positively predict the treatment response to SSRIs treatment in patients (β=0.441, P=0.014). ConclusionThe event-based prospective memory function of patients with obsessive-compulsive disorder can positively predict SSRIs treatment outcome, and patients with better prospective memory performance yield better treatment responses.

ObjectiveTo study the prospective memory deficits of obsessive-compulsive disorder patients and unaffected first-degree relatives of patients, so as to validate the possibility of prospective memory as an endophenotype of obsessive-compulsive disorder. MethodsHealthy controls, obsessive-compulsive disorder patients and unaffected first-degree relatives of patients, each with 25 cases, matched for age, education, gender, IQ and marriage status were enrolled. The standardized prospective memory paradigm with a multi-trial design was conducted, and the accuracy was used as an indicator of prospective memory function. ResultsThe accuracy of event- and time-based prospective memory tasks of obsessive-compulsive disorder patients was lower than that of healthy controls, with statistical differences [(0.74±0.24) vs. (0.88±0.13), d=-0.140, P=0.044; (0.77±0.21) vs. (0.93±0.10), d=-0.164, P=0.011]. The accuracy of event-based prospective memory task of unaffected first-degree relatives was also lower than that of healthy controls, with statistical difference [(0.73±0.20) vs. (0.88±0.13), d=-0.144, P=0.036]. ConclusionObsessive-compulsive disorder patients has extensive prospective memory deficits, indicating that prospective memory may be an endophenotype of obsessive-compulsive disorder.
