Objective:To investigate the correlation between postoperative spinal sagittal parameters and reinforced vertebral recompression fractures in patients with osteoporotic vertebral compression fractures (OVCFs) who have undergone percutaneous kyphoplasty (PKP).Methods:Data on patients with OVCFs treated with PKP at the Department of Orthopaedics, Second Affiliated Hospital of Soochow University, from August 2020 to August 2024, were collected. Among these, 31 patients who underwent single-segment PKP experienced postoperative reinforced vertebral recompression fractures (recompression fracture group), comprising 8 males and 23 females, with a mean age of 73.74±8.76 years, a body mass index (BMI) of 23.83±1.87 kg/m 2, and a bone mineral density T-value of -2.29±0.55. The remission rate of the visual analogue scale (VAS) after surgery was 80.14%±4.86%, with a mean volume of bone cement used at 5.37±0.69 ml. The surgical segments involved included T 5 (1 case), T 8 (1 case), T 10 (1 case), T 11 (4 cases), T 12 (9 cases), L 1 (7 cases), L 2 (4 cases), L 3 (2 cases), and L 4 (2 cases). Following a 1∶1 matching principle, 31 patients whose vertebrae did not experience reinforced recompression fractures during the same period (non-recompression fracture group) were included. This group also comprised 8 males and 23 females, with a mean age of 74.88±8.31 years, a BMI of 23.15±2.04 kg/m 2, a bone mineral density T-value of -2.76±0.64, and a VAS remission rate of 79.75%±5.01%. The mean volume of bone cement used in this group was 5.41±0.72 ml. The surgical segments involved included T 8 (1 case), T 10 (1 case), T 11 (4 cases), T 12 (8 cases), L 1 (7 cases), L 2 (5 cases), L 3 (2 cases), L 4 (2 cases), and L 5 (1 case). There were no statistically significant differences in the aforementioned indicators between the two patient groups ( P>0.05). A comparison of the postoperative spinal sagittal parameters between the two groups was conducted, focusing on the local kyphosis angle (LKA), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and the lumbar-pelvic matching value (PI-LL). Indicators that exhibited statistically significant differences were included in the binary logistic regression analysis to evaluate the impact of spinal sagittal parameters following PKP on the recompression of the reinforced vertebral. Results:The time to reinforced vertebral recompression fractures after PKP ranged from 35 to 184 d, with a median of 69 d. The TK in the recompression fracture group (46.56°±7.02°) was significantly greater than that in the non-recompression fracture group (41.95°±5.76°). Additionally, the LKA, PI and SS were all smaller in the recompression fracture group (9.84°±2.13°, 41.36°±4.27°, 22.69°±5.53°, respectively) compared to the non-recompression fracture group (12.37°±2.64°, 48.09°±6.33°, 28.41°±7.64°), with all differences being statistically significant ( P<0.05). However, no significant differences were observed between the LL, PT, and PI-LL values ( P>0.05). TK, LKA, PI, and SS were included in the binary logistic regression analysis, which indicated that TK [ OR=1.533, 95% CI(1.47, 1.59)] after PKP was positively correlated with the occurrence of reinforced vertebral recompression fractures. Conversely, LKA [ OR=0.882, 95% CI(0.80, 0.96)], PI [ OR=0.815, 95% CI(0.71, 0.91)], and SS [ OR=0.833, 95% CI(0.73, 0.93)] were negatively correlated. Conclusions:The incidence of reinforced vertebral recompression fractures following PKP is associated with spinal sagittal parameters, including TK, LKA, PI, and SS. Specifically, a larger TK and smaller values of LKA, PI, and SS are correlated with an elevated risk of reinforced vertebral recompression fractures.

Knee osteoarthritis(KOA)is a common chronic degenerative bone and joint disease characterized by degeneration and wear of knee cartilage.It is commonly found in middle-aged and elderly people and seriously impacts on their lower limb activity and quality of life.At present,the treatment of early and middle stage KOA mainly relies on the conservative methods such as oral medication,joint injection,topical patches and traditional Chinese medicine.Platelet rich plasma(PRP),as an autologous platelet concentrate,is rich in various growth factors and has no risk of immune rejection.In recent years,it has been widely used in the repair of bone,joint,and soft tissue injuries.However,the short biological half-life of growth factors in PRP and the fluidity of injection sites can result in insufficient binding force,short action time,poor target therapy efficacy,and the need for repeated injections in the joint cavity,which will increase the risk of iatrogenic infections.Hydrogels are cross-linked polymer networks containing water,and their high histocompatibility and drug release have attracted much attention.The slow and continuous release of drug is achieved by loading PRP onto hydrogel.Its unique adhesion reduces the flow of drug in the joint,thus extending the local action time of PRP and reducing the need for repeated injection.This article reviews the biological characteristics of PRP and hydrogel,the mechanism of action and clinical application of PRP loaded hydrogel in the treatment of KOA,and analyzes the existing problems and challenges,aiming to provide more effective treatment options for KOA patients through the in-depth discussion of this new treatment method.

Objective To investigate the effects of Tuina targeting different body parts on the behaviors and gut microflora of rat models with valproic acid(VPA)-induced autistic spectrum disorder(ASD). Methods Twenty female Sprague Dawley(SD)rats with 12.5 d of pregnancy were randomly divided into VPA model group[intraperitoneal injection of VPA(600 mg/kg),n=15]and saline group(intraperitoneal injection of equal amount of normal saline,n=5).The offspring male rats injected with saline were secleted as control group.The offspring male rats injected with VPA were randomly divided into VPA,dorsal,and abdominal groups(n=7 in each group).On the 21st day after birth,three-chamber social test,open field test,and marble-burying test were carried out to observe the social abilities,anxiety behaviors,and stereotypi-cal behaviors of rats in the four groups.Rats in dorsal and abdominal groups underwent Tuina for 14 d,twice a day.On the 35th day,behavioral tests were conducted again,and in-testinal contents were taken for species composition and structural analysis,as well as mark-er and differential species analysis. Results(i)According to behavioral observations,compared with VPA group,the social and movement time in the central open field of rats in dorsal group increased significantly(P<0.05),and the number of buried marbles decreased markedly(P<0.01),indicating improve-ment on their social abilities,anxiety behaviors,and stereotypical behaviors as consequences of dorsal Tuina;and the number of buried marbles was reduced as well in abdominal group when compared with VPA group(P<0.05),suggesting the improvement on their stereotypi-cal behaviors following abdominal Tuina.In the marble-burying test,the number of marbles buried in dorsal group was less than in abdominal group,and the stereotypical behaviors were improved more significantly(P<0.05),and there were no significant differences in the three-chamber social and open field tests between the two groups(P>0.05).(ii)In accor-dance with intestinal microflora detection results,compared with VPA group,both dorsal and abdominal groups showed increased richness(P<0.05)and elevated diversity(P<0.05 in dorsal group and P<0.01 in abdominal group)in intestinal microflora.The results of differen-tial analysis indicated that at the phylum level,compared with VPA group,the relative abun-dance of Firmicutes in rats in abdominal group showed a significant reduction trend(P<0.05);at the genus level,compared with VPA group,the relative abundance of Lactobacillus in rats in dorsal and abdominal groups decreased significantly(P<0.05).Dorsal group also showed significant increase in the genus Blautia in the analysis of marker species compared with VPA group(P<0.05). Conclusion Tuina impacted the behavior and gut microflora structure of ASD model rats.Dorsal intervention had a significant effect on social abilities,anxiety behaviors,and stereo-typical behaviors of ASD model rats,while abdominal intervention only had an obvious effect on stereotypical behaviors.Both dorsal and abdominal interventions increased the richness and diversity of gut microflora of ASD model rats,with abdominal intervention improving the intestinal microbial diversity more significantly and resulting in a more uniform species dis-tribution.

BACKGROUND: Programmed cell death protein 1 (PD-1) combined with platinum containing dual drug chemotherapy is a new adjuvant treatment option for operable stage III non-small cell lung cancer (NSCLC), and the quality assurance of clinical trials of related drugs plays a crucial role in the results of the clinical trials. This study aims to explore the impact of adverse events (AEs) supervision on reducing treatment-related AEs in patients. METHODS: 66 NSCLC patients admitted to Shanghai Chest Hospital from July 2020 to October 2021 were prospectively collected. All the patients received 3 cycles of neoadjuvant treatment of Camrelizumab in combination with Docetaxel and Cisplatin. 4 weeks-6 weeks after neoadjuvant therapy, the patients accepted surgical treatment. One cycle of postoperative adjuvant treatment was given within 30 days after surgery, and 3 weeks after the completion of postoperative adjuvant treatment, Camrelizumab consolidation treatment was intiated, with a total of 13 cycles. The quality of life-C30 (QoL-C30) was used to measure patients' quality of life and the occurrence of AEs was monitored. RESULTS: The overall safety is good, with a total of 300 AEs occurring in 66 patients, including 282 cases of grade 1-2 AEs and 18 cases of grades 3-4 AEs. The most common grades 3-4 AEs associated with PD-1 antibodies occurred in 6 cases (9.1%). Neoadjuvant therapy supervision can lead to a decrease in patients' QOL-C30 scores (P<0.05) and an improvement in their quality of life. CONCLUSIONS Camrelizumab combined with Docetaxel and Cisplatin can be used as a new adjuvant treatment for operable stage III NSCLC. Through the observation and control of AEs, treatment measures can be taken in time to reduce further complications, ensure patient' safety, and ensure the authenticity, scientificity and reliability of clinical trial data.

Circular RNAs (circRNAs) are endogenous non-coding RNAs with covalently closed structures, which have important functions in plants. However, their biogenesis, degradation, and function upon treatment with gibberellins (GAs) and auxins (1-naphthaleneacetic acid, NAA) remain unknown. Here, we systematically identified and characterized the expression patterns, evolutionary conservation, genomic features, and internal structures of circRNAs using RNase R-treated libraries from moso bamboo (Phyllostachys edulis) seedlings. Moreover, we investigated the biogenesis of circRNAs dependent on both cis- and trans-regulation. We explored the function of circRNAs, including their roles in regulating microRNA (miRNA)-related genes and modulating the alternative splicing of their linear counterparts. Importantly, we developed a customized degradome sequencing approach to detect miRNA-mediated cleavage of circRNAs. Finally, we presented a comprehensive view of the participation of circRNAs in the regulation of hormone metabolism upon treatment of bamboo seedlings with GA and NAA. Collectively, our study provides insights into the biogenesis, function, and miRNA-mediated degradation of circRNAs in moso bamboo.

Spinal cord injury (SCI) is a disabling and destructive central nervous system injury that has not yet been successfully treated at this stage. Three-dimensional (3D) bioprinting has become a promising method to produce more biologically complex microstructures, which fabricate living neural constructs with anatomically accurate complex geometries and spatial distributions of neural stem cells, and this is critical in the treatment of SCI. With the development of 3D printing technology and the deepening of research, neural tissue engineering research using different printing methods, bio-inks, and cells to repair SCI has achieved certain results. Although satisfactory results have not yet been achieved, they have provided novel ideas for the clinical treatment of SCI. Considering the potential impact of 3D bioprinting technology on neural studies, this review focuses on 3D bioprinting methods widely used in SCI neural tissue engineering, and the latest technological applications of bioprinting of nerve tissues for the repair of SCI are discussed. In addition to introducing the recent progress, this work also describes the existing limitations and highlights emerging possibilities and future prospects in this field.
