RESUMO
Background: Osteoking has been extensively used for the treatment of knee osteoarthritis (KOA). However, it is lack of high-quality evidence on the clinical efficacy of Osteoking against KOA and the comparison with that of nonsteroidal anti-inflammatory drugs (NSAIDs). Aims: To evaluate the efficacy and safety of Osteoking in treating KOA. Methods: In the current study, a total of 501 subjects were recruited from 20 medical centers, and were divided into the Osteoking treatment group (n = 428) and the NSAIDs treatment group (n = 73). The Propensity Score Matching method was used to balance baseline data of different groups. Then, the therapeutic effects of Osteoking and NSAIDs against KOA were evaluated using VAS score, WOMAC score, EQ-5D-3L and EQ-VAS, while the safety of the two treatment were both assessed based on dry mouth, dizziness, diarrhea, etc. Results: After 8 weeks of treatment, the Osteoking group was compared with the NSAIDs group, the VAS score [2.00 (1.00, 3.00) vs. 3.00 (2.00, 4.00)], WOMAC pain score [10.00 (8.00, 13.00) vs. 11.00 (8.00, 16.00) ], WOMAC physical function score [32.00 (23.00, 39.00) vs. 39.07 ± 16.45], WOMAC total score [44.00 (31.00, 55.00) vs. 53.31 ± 22.47) ], EQ-5D-3L score [0.91 (0.73, 0.91) vs. 0.73 (0.63, 0.83) ] and EQ-VAS score [80.00 (79.00, 90.00) vs. 80.00 (70.00, 84.00) ] were improved by the treatment of Osteoking for 8 weeks more effectively than that by the treatment of NSAIDs. After 8 weeks of treatment with Osteoking, the VAS scores of KOA patients with the treatment of Osteoking for 8 weeks were reduced from 6.00 (5.00, 7.00) to 2.00 (1.00, 3.00) (p < 0.05), which was better than those with the treatment of NSAIDs starting from 2 weeks during this clinical observation. Importantly, further subgroup analysis revealed that the treatment of Osteoking was more suitable for alleviating various clinical symptoms of KOA patients over 65 years old, with female, KL II-III grade and VAS 4-7 scores, while the clinical efficacy of NSAIDs was better in KOA patients under 65 years old and with VAS 8-10 scores. Of note, there were no differences in adverse events and adverse reactions between the treatment groups of the two drugs. Conclusion: Osteoking may exert a satisfying efficacy in relieving joint pain and improving life quality of KOA patients without any adverse reactions, especially for patients with KL II-III grades and VAS 4-7 scores.

RESUMO
Background: All available methods for reconstruction after proximal humerus tumor resection have disadvantages, and the optimal reconstruction method remains uncertain. This study aimed to design a novel 3D-printed glenohumeral fusion prosthesis and verify its feasibility and safety using biomechanical methods. Methods: We verified the feasibility and safety of the 3D-printed glenohumeral fusion prosthesis by finite element analysis and biomechanical experimentation. In the finite element analysis, three reconstruction methods were used, and displacement and von Mises stress were observed; on this basis, in the biomechanical experiment, models constructed with sawbones were classified into two groups. The forceâdisplacement curve of the 3D-printed prosthesis was evaluated. Results: In terms of displacement, the finite element analysis showed greater overall stability for the novel prosthesis than traditional glenohumeral joint arthrodesis. There was no obvious stress concentration in the internal part of the 3D-printed glenohumeral fusion prosthesis; the stable structure bore most of the stress, and the force was well distributed. Adding lateral plate fixation improved the stability and mechanical properties of the prosthesis. Furthermore, the biomechanical results showed that without lateral plate fixation, the total displacement of the prosthesis doubled; adding lateral plate fixation could reduce and disperse strain on the glenoid. Conclusion: The design of the 3D-printed glenohumeral fusion prosthesis was rational, and its stability and mechanical properties were better than those of traditional glenohumeral joint arthrodesis. Biomechanical verification demonstrated the feasibility and safety of this prosthesis, indicating its potential for proximal humerus bone defect reconstruction after tumor resection.
RESUMO
PURPOSE: To develop a novel classification of sagittal en bloc resection (SEBR) based on anatomical locations for thoracolumbar spine tumors and assess the clinical outcomes of this surgical procedure. METHODS: 31 patients with thoracolumbar tumours treated with SEBR were enrolled in this study. The individualized surgical strategy was adopted based on our surgical classification. Demographics, perioperative outcomes, complications and postoperative outcomes were assessed. RESULTS: Based on our surgical classifications, patients were divided into four types. All bony resection margins were negative, wide resection was achieved in 25 patients, marginal resection in four, and intralesional resection in two. 18 patients underwent anterior reconstruction. Complications were encountered in five patients, and instrumentation failure occurred in one patient. The median follow-up was 24 (range, 6-72) months and recurrence was found in only one patient. CONCLUSION: SEBR is a safe and effective surgical procedure for patients with thoracolumbar spinal tumours in specific anatomical locations. The proposed surgical classification covers all SEBR types and is easy to apply, it may assist surgical decision-making in patients with spinal tumours.

As a crucial member of pattern-recognition receptors (PRRs), the Tolls/Toll-like receptors (TLRs) gene family has been proven to be involved in innate immunity in crustaceans. In this study, nine members of TLR gene family were identified from the mud crab (Scylla paramamosain) transcriptome, and the structure and phylogeny of different SpTLRs were analyzed. It was found that different SpTLRs possessed three conserved structures in the TIR domain. Meanwhile, the expression patterns of different Sptlr genes in examined tissues detected by qRT-PCR had wide differences. Compared with other Sptlr genes, Sptlr-6 gene was significantly highly expressed in the hepatopancreas and less expressed in other tissues. Therefore, the function of Sptlr-6 was further investigated. The expression of the Sptlr-6 gene was up-regulated by Poly I: C, PGN stimulation and Vibrio parahaemolyticus infection. In addition, the silencing of Sptlr-6 in hepatopancreas mediated by RNAi technology resulted in the significant decrease of several conserved genes involved in innate immunity in mud crab after V. parahaemolyticus infection, including relish, myd88, dorsal, anti-lipopolysaccharide factor (ALF), anti-lipopolysaccharide factor 2 (ALF-2) and glycine-rich antimicrobial peptide (glyamp). This study provided new knowledge for the role of the Sptlr-6 gene in defense against V. parahaemolyticus infection in S. paramamosain.

Aims: The aim of this study was to investigate the safety and efficacy of 3D-printed modular prostheses in patients who underwent joint-sparing limb salvage surgery (JSLSS) for malignant femoral diaphyseal bone tumours. Methods: We retrospectively reviewed 17 patients (13 males and four females) with femoral diaphyseal tumours who underwent JSLSS in our hospital. Results: In all, 17 patients with locally aggressive bone tumours (Enneking stage IIB) located in the femoral shaft underwent JSLSS and reconstruction with 3D-printed modular prostheses between January 2020 and June 2022. The median surgical time was 153 minutes (interquartile range (IQR) 117 to 248), and the median estimated blood loss was 200ml (IQR 125 to 400). Osteosarcoma was the most common pathological type (n = 12; 70.6%). The mean osteotomy length was 197.53 mm (SD 12.34), and the median follow-up was 25 months (IQR 19 to 38). Two patients experienced local recurrence and three developed distant metastases. Postoperative complications included wound infection in one patient and screw loosening in another, both of which were treated successfully with revision surgery. The median Musculoskeletal Tumor Society score at the final follow-up was 28 (IQR 27 to 28). Conclusion: The 3D-printed modular prosthesis is a reliable and feasible reconstruction option for patients with malignant femoral diaphyseal tumours. It helps to improve the limb salvage rate, restore limb function, and achieve better short-term effectiveness.
RESUMO
Background: Oral Submucosal Fibrosis (OSF) and Oral Leukoplakia (OLK) are well-known oral potentially malignant disorders, and cases of Oral Submucosal Fibrosis concomitant Oral Leukoplakia (OSF+OLK) are now being reported clinically. DNA image cytometry is an objective and non-invasive method for monitoring the risk of precancerous lesions in the oral cavity. Methods: A total of 111 patients with clinically characterized oral mucosal lesions underwent simultaneous and independent histopathological and DNA imaging cytometry assessments. Clinical data were also collected for each patient. Results: The frequency of DNA content abnormality was higher in the tongue than in other oral sites (P = 0.003) for OLK. The frequency of DNA content abnormality was higher in the tongue than in other oral sites (P = 0.035) for OSF+OLK. The differences of DNA content abnormality in age, sex, dietary habit, smoking, and alcohol intake were not observed in OLK and OSF+OLK. The study indicates an association between DNA content abnormality and pathological examination in OSF+OLK ( χ2 test, P = 0.007). OLK showed higher sensitivity and specificity than OSF, while the sensitivity and specificity of OSF+OLK are higher than OLK only and OSF only. Conclusion: DNA image cytometry can be utilized as an adjunctive device for the initial detection of oral potentially malignant disorders that require further clinical management.
RESUMO
As the most important cultural crustacean species worldwide, studies about Pacific white shrimp (Litopenaeus vannamei) have received more attention. It has been well-documented that various pathogens could infect L. vannamei, resulting in huge economic losses. The studies about the responding mechanism of L. vannamei to sole pathogens such as Vibrio parahaemolyticus and white spot virus (WSSV) have been extensively reported, while the studies about the differently responding mechanisms remain unclear. In the present study, we identified the differently expressed genes (DEGs) of L. vannamei hemocytes post V. parahaemolyticus and WSSV infection with RNA-seq technology and compared the DEGs between the two groups. The results showed 2672 DEGs post the V. parahaemolyticus challenge (1079 up-regulated and 1593 down-regulated genes), while 1146 DEGs post the WSSV challenge (1067 up-regulated and 513 down-regulated genes). In addition, we screened the genes that simultaneously respond to WSSV and V. parahaemolyticus (434), solely respond to WSSV (1146), and V. parahaemolyticus challenge (2238), respectively. Six DEGs involved in innate immunity were quantified to validate the RNA-seq results, and the results confirmed the high consistency of both methods. Furthermore, we found plenty of innate immunity-related genes that responded to V. parahaemolyticus and WSSV infection, including pattern recognition receptors (PRRs), the proPO activating system, antimicrobial peptides (AMPs), and other immunity-related proteins. The results revealed that they were differently expressed after different pathogen challenges, demonstrating the complex and specific recognition systems involved in defending against the invasion of different pathogens in the environment. The present study improved our understanding of the molecular response of hemocytes of L. vannamei to V. parahaemolyticus and WSSV stimulation.

RESUMO
The activation of YAP/TAZ, a pair of paralogs of transcriptional coactivators, initiates a dysregulated transcription program, which is a key feature of human cancer cells. However, it is not fully understood how YAP/TAZ promote dysregulated transcription for tumor progression. In this study, we employed the BioID method to identify the interactome of YAP/TAZ and discovered that YAP/TAZ interact with multiple components of SRCAP complex, a finding that was further validated through endogenous and exogenous co-immunoprecipitation, as well as immunofluorescence experiments. CUT&Tag analysis revealed that SRCAP complex facilitates the deposition of histone variant H2A.Z at target promoters. The depletion of SRCAP complex resulted in a decrease in H2A.Z occupancy and the oncogenic transcription of YAP/TAZ target genes. Additionally, the blockade of SRCAP complex suppressed YAP-driven tumor growth. In a genetically engineered lung adenocarcinoma mouse model and non-small cell lung cancer patients, SRCAP complex and H2A.Z deposition were found to be upregulated. This upregulation was statistically correlated with YAP expression, pathological stages, and poor survival in lung cancer patients. Together, our study uncovers that SRCAP complex plays a critical role in YAP/TAZ oncogenic transcription by coordinating H2A.Z deposition during cancer progression, providing potential targets for cancer diagnosis and prevention.

Biomolecular condensates have been proposed to mediate cellular signaling transduction. However, the mechanism and functional consequences of signal condensates are not well understood. Here we report that LATS2, the core kinase of the Hippo pathway, responds to F-actin cytoskeleton reduction and forms condensates. The proline-rich motif (PRM) of LATS2 mediates its condensation. LATS2 partitions with the main components of the Hippo pathway to assemble a signalosome for LATS2 activation and for its stability by physically compartmentalizing from E3 ligase FBXL16 complex-dependent degradation, which in turn mediates yes-associated protein (YAP)-transcriptional coactivator with PDZ-binding motif (TAZ) recruitment and inactivation. This oncogenic FBXL16 complex blocks LATS2 condensation by binding to the PRM region to promote its degradation. Disruption of LATS2 condensation leads to tumor progression. Thus, our study uncovers that the signalosomes assembled by LATS2 condensation provide a compartmentalized and reversible platform for Hippo signaling transduction and protein stability, which have potential implications in cancer diagnosis and therapeutics.

Bone metastasis (BM) is one of the most common complications of advanced cancer. Immunotherapy for bone metastasis of lung cancer (LCBM) is not so promising and the immune mechanisms are still unknown. Here, we utilized a model of BM by injecting cancer cells through caudal artery (CA) to screen out a highly bone metastatic derivative (LLC1-BM3) from a murine lung cancer cell line LLC1. Mass spectrometry-based proteomics was performed in LLC1-parental and LLC1-BM3 cells. Combining with prognostic survival information from patients with lung cancer, we identified serpin B9 (SB9) as a key factor in BM. Molecular characterization showed that SB9 overexpression was associated with poor prognosis and high bone metastatic burden in lung cancer. Moreover, SB9 could increase the ability of lung cancer cells to metastasize to the bone. The mechanistic studies revealed that tumor-derived SB9 promoted BM through an immune cell-dependent way by inactivating granzyme B, manifesting with the decreased infiltration of cytotoxic T cells and increased expression level of exhausted markers. A specific SB9-targeting inhibitor [1,3-benzoxazole-6-carboxylic acid (BTCA)] significantly suppressed LCBM in the CA mouse model. This study reveals that SB9 may serve as a therapeutic target and potential prognostic marker for patients with LCBM. IMPLICATIONS: SB9 as a therapeutic target for LCBM.

The first year of university is one of the most difficult times in a student's life due to numerous changes that occur. This cross-sectional study explores the concept of parental and peer attachment, which has been researched for its ability to predict students' success in higher education. Yet, less research has investigated the mechanisms underpinning the relationship between attachment and university adjustment among first-year students. Hence, the aim of this study was to examine the impact of parent and peer attachment on first-year university students, and understand how these attachments can facilitate university adjustment through identity exploration. This investigation is underpinned by Bowlby and Ainsworth's attachment theory and Arnett's emerging adulthood theory. Data were collected from 568 first-year students at a public university in Sabah, Malaysia, via adapted questionnaires. Structural equation modelling was employed using SmartPLS Software 3.0 to analyse the data. The study found that identity exploration mediates the relationship between parental trust, peer communication, and university adjustment. The findings of this study provide valuable insights for professionals working with emerging adult clients, especially those in higher education institutions, aiming to enhance the adjustment level among first-year students.

The objective of this study was to assess the factor structure of the 26-item Eating Attitude Test (EAT-26) through confirmatory factor analysis (CFA) among 1,084 undergraduate students in Malaysia. The initial findings indicated a lack of support for the proposed three-factor structure. Model modifications were made due to the inadequate initial fit. The fit of the model was significantly improved by excluding items with factor loadings below 0.40 and integrating residual covariances. In conclusion, it is necessary to make contextual modifications to the EAT-26 in order to effectively utilize it among Malaysian undergraduates. This highlights the significance of cultural adaptations in psychological instruments.
RESUMO
The Muscularity Bias Internalization Scale (MBIS) captures an individual's endorsement of stereotypical beliefs about muscularity and engagement in self-stigmatizing evaluations about their muscularity. The MBIS has been validated in Chinese men and Lebanese men and women, showing strong internal consistency reliability and construct validity. Because muscularity-related body image concerns are present in Chinese women, there is a need for research to validate the MBIS in Chinese women. The present study examined the factor structure and psychometric properties of the MBIS in a sample of Chinese women. Exploratory factor analysis (n = 300) identified a two-factor structure which showed adequate model fit in confirmatory factor analysis (n = 300), with χ2(76) = 294.63 (p < .001), CFI = 0.98, TLI = 0.98, and SRMR = 0.05. Results also showed that the MBIS in women had adequate internal consistency, two-week test-retest reliability, and good construct validity. Findings suggest that the MBIS is a useful tool for assessing muscularity bias internalization, a potentially important risk factor for muscularity-oriented eating and body image disturbances.

Strong acid, alkali, or active chemicals are generally employed in chemical mechanical polishing (CMP) slurry for the ultra-precision machining of semiconductor substrates, obstructing further improvement in machining accuracy and reduction in damaged layers. Understanding the material removal behavior of abrasives, which combines mechanical and chemical actions during nanoscale abrasive polishing, poses a significant challenge. In this study, the interfacial interaction mechanisms between abrasives and substrates during nanoscale polishing with only deionized water used as coolant were analyzed by utilizing concerned experiments and molecular dynamics (MD) simulations. The results showed that ultra-smooth SiC and sapphire substrate surfaces only with damage layer thicknesses of 2.06 nm and 0.76 nm were obtained by employing diamond abrasive and alumina abrasive, respectively. Tribochemical reactions could occur on substrate surfaces under the repeated interfacial fiction of fine abrasives without any chemical reagents during nanoscale polishing. The tribochemical reactions mainly depended on the chemical compatibility between the abrasives and substrates when the material removal size of abrasives was limited to nanoscale, not abrasive hardness. Furthermore, a new method of abrasive selection is proposed and widely applied in the ultra-precision polishing of semiconductor substrates, which could not only improve removal efficiency but also ensure good surface quality.
RESUMO
This paper demonstrates an AlGaInP-based 620-nm red micro-light-emitting-diode (µ-LED) array and studies the enhancement effect of the surface treatments using (NH4)2Sx solutions by comparing the characteristics of µ-LED arrays with and without the (NH4)2Sx treatment. Furthermore, our µ-LED array demonstrates a measurement of the current efficiency (2.6 cd/A), which improves the light output uniformity. Also, we apply a setup for measuring the response time at the fast ns-level to analyze the effect of passivation in AlGaInP-based µ-LED arrays.
RESUMO
Treatments for osteosarcoma (OS) with pulmonary metastases reach a bottleneck with a survival rate of 10-20%. The suppressive tumor associated macrophages(TAMs) and CD47 over-expression greatly lead to the treatment failure. Sonodynamic therapy (SDT) can generate ROS with deep tumor penetration to induce tumor cell apoptosis, which is reported to further induce M1 macrophage polarization. CD47 inhibition combined with SDT to synergistically modulate TAMs may induce superior effects for OS treatment. In this work, for the first time, a biomimetic nanodrug named MPIRx was deveploped by loading IR780 (a sonosensitizer) and RRx-001 (a CD47 inhibitor) in PEG-PCL nanomicelles and then coating with OS cell membranes. After ultrasound activation, the nanodrug significantly inhibited OS proliferation and migration, induced apoptosis and immunogenic cell death in OS cells. Furthermore, MPIRx could guide macrophage migrating towards tumor cells and promote M1-type polarization while increasing the phagocytosis activity of macrophages on OS cells. Ultimately, MPIRx showed good tumor accumulation in vivo and successfully inhibited subcutaneous OS and orthotopic tumor with deterioration of pulmonary metastasis. Overall, by creating a local oxidative microenvironment and modulating the TAMs/CD47 in tumor tissue, the MPIRx nanodrug presents a novel strategy for macrophage-related immunotherapy to successfully eliminate OS and inhibit the intractable pulmonary metastasis.

BACKGROUND: Minimally invasive separation surgery (MISS) is a safe and effective surgical technique, the current optimal treatment for spinal metastases. However, the learning curve for this technique has not been analyzed. This study aimed to define and analyze the surgical learning curve of MISS for the treatment of spinal metastases with small incision and freehand pedicle screw fixation. METHODS: A continuous series of 62 patients with spinal metastases who underwent MISS were included. Each patient's operative data were accurately counted. The improvement of the patients' neurological function was followed up after surgery to evaluate the surgical treatment effect. Logarithmic curve-fit regression was used to analyze the surgical learning curve of MISS. The number of cases needed to achieve proficiency was analyzed. Based on this cut-off point, this series of cases was divided into the early phase and later phase groups. The influence of the time sequence of MISS on surgical data and surgical efficacy was analyzed. RESULTS: The operative time decreased gradually with the number of surgical cases increasing and stabilized after the 20th patient. There was no statistical difference in demographic characteristics and preoperative characteristics between the two groups. The mean operative time in the later phase group was about 39 min shorter than that in the early phase group (mean 227.95 vs. 189.02 min, P = 0.027). However, it did not affect other operative data or the surgical treatment effect. CONCLUSION: The learning curve of MISS for spinal metastases is not steep. With the increase of surgeons' experience, the operative time drops rapidly and stabilizes within a certain range. MISS can be safely and effectively performed at the beginning of a surgeon's caree.

ETHNOPHARMACOLOGICAL RELEVANCE: Shugan granule is derived from Xiaoyao powder, a traditional Chinese medicine that has been shown to be effective in treating emotional disorders. At present, there is no standard drug treatment for mixed anxiety-depressive disorder (MADD), and no evidence-based clinical trial has been performed for any drug, meaning MADD patients are unable to obtain standardized treatment. AIM OF THE STUDY: The purpose of this clinical trial was to test the clinical efficacy and safety of Shugan granules in the treatment of MADD, and to provide clinical trial-based support along with drug recommendations for the treatment of MADD. MATERIALS AND METHODS: A multicenter, randomized, double-blind, placebo-controlled study was conducted on 400 patients with MADD recruited from January 1, 2019 to December 31, 2020, and they were randomly divided into test and placebo groups with a 1:1 ratio. Subjects in the test group (n = 200) received oral administration of Shugan granules, while subjects in the placebo group (n = 200) received oral administration of a Shugan granule simulator. The treatment lasted for 8 weeks. The Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale-17 (HAMD-17), Clinical Global Impression Scale (CGIS), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS) were used to evaluate efficacy. In addition, the traditional Chinese medicine (TCM) syndrome scale for MADD was developed to observe improvements of related symptoms in patients after treatment based on the disease guidelines of TCM and the clinical manifestations of depression. Furthermore, the safety of Shugan granules was evaluated during and after treatment. RESULTS: After 8 weeks of treatment, the total scores for HAMA, HAMD, SAS, and SDS in the test group were significantly lower than those in the placebo group (P < 0.01). The proportion of patients with efficacy index (EI) > 1 for the CGIS score in the test group was significantly higher than that in the placebo group (P < 0.01). The efficacy of treatment in the test group based on the TCM syndrome scale was 70.16% and 88.27% after 4 weeks and 8 weeks, respectively, which was significantly higher than that in the placebo group (44.27% and 66.67% after 4 weeks and 8 weeks, respectively; P < 0.01). The disappearance rate of single symptoms in the test group was 20-30% higher than that in the placebo group, with a significant difference between groups (P < 0.05). During the treatment period, the incidence of adverse reactions was 2.05% in the test group and 2.06% in the placebo group, with no significant differences noted (P = 1.0000). CONCLUSION: Shugan granule was more effective than placebo in the treatment of MADD. Moreover, there was no significant difference between the two groups in terms of safety. This paper provides a clinical therapeutic regime using Shugan granule for the treatment of MADD.
