OBJECTIVE:Neuromuscular exercise is a new comprehensive rehabilitation therapy in recent years,but its effect on knee osteoarthritis is still controversial.The purpose of this paper is to systematically evaluate the efficacy of neuromuscular exercise on knee osteoarthritis pain and function. METHODS:The randomized controlled trials addressing neuromuscular exercise in the treatment of knee osteoarthritis pain and function were retrieved from PubMed,Cochrane Library,Embase,EBSCO,CNKI,Web of Science,China Biomedical Database(CBM),VIP,and WanFang Database.The retrieval time ranged from database inception to October 2023.The neuromuscular training group(experimental group)was given neuromuscular training or neuromuscular training as the main intervention;the control group was a blank group or given conventional rehabilitation.Outcome indicators included the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score,walking time,knee stability,and the maximum number of knee flexion in 30 seconds.The risk of bias was evaluated by the Cochrane Collaboration tool and the Physiotherapy Evidence Database.Meta-analysis was performed using RevMan 5.4 software. RESULTS:A total of 11 randomized controlled trials were included,and 628 samples were extracted.The results of Meta-analysis showed that the experimental group was superior to the control group in terms of WOMAC pain score[standardized mean difference(SMD)=0.38,95%confidence interval(CI):0.08-0.69,P=0.01],knee stability(SMD=0.57,95%CI:0.23-0.92,P=0.001),the maximum number of knee joint flexion in 30 seconds(SMD=0.35,95%CI:0.05-0.65,P=0.02),and WOMAC physical function score(SMD=-0.79,95%CI:-1.30 to-0.28,P=0.002).In both groups,walking speed was increased and walking ability was improved in patients with knee osteoarthritis,but there was no significant difference(walking time:SMD=-0.22,95%CI:-0.48-0.03,P=0.09). CONCLUSION:Neuromuscular exercise can effectively improve knee joint pain,enhance the stability of the knee joint,and promote functional recovery in patients with knee osteoarthritis.However,more high-quality randomized controlled trials are still needed to further confirm the research.

In different stages of schizophrenia (SZ), alterations in gray matter volume (GMV) of patients are normally regulated by various pathological mechanisms. Instead of analyzing stage-specific changes, this study employed a multivariate structural covariance model and sliding-window approach to investigate the illness duration-related developmental trajectory of GMV in SZ. The trajectory is defined as a sequence of brain regions activated by illness duration, represented as a sparsely directed matrix. By applying this approach to structural magnetic resonance imaging data from 145 patients with SZ, we observed a continuous developmental trajectory of GMV from cortical to subcortical regions, with an average change occurring every 0.208 years, covering a time window of 20.176 years. The starting points were widely distributed across all networks, except for the ventral attention network. These findings provide insights into the neuropathological mechanism of SZ with a neuroprogressive model and facilitate the development of process for aided diagnosis and intervention with the starting points.

OBJECTIVE: To evaluate the short-term clinical efficacy of external fixation and internal fixation with steel plate in the treatment of unstable distal radius fractures (AO-23C type), based on the principles of Chinese osteosynthesis (CO). METHODS: Forty-eight patients with unstable distal radius fractures between January 2022 and February 2023 were retrospectively analyzed and divided into the CO external fixation group and internal fixation group. CO external fixation group consisted of 25 patients, including 7 males and 18 females, aged from 37 to 56 years old with an average of ( 52.6±11.3) years old. Among them, there were 7 patients of traffic accidents and 18 patients of falls, resulting in a total of 25 patients of closed fractures and no open fractures, the treatment was conducted using closed reduction and CO external fixation. The internal fixation group consisted of 23 patients, comprising 8 males and 15 females, age ranged from 41 to 59 years old, with an average age of(53.3±13.7) years old. Among them, 8 patients resulted from car accidents while the remaining 15 patients were caused by falls. All 23 patients were closed fractures without any open fractures observed. The technique of open reduction and internal fixation with steel plate was employed. The perioperative data, including injury-operation time, operation duration, blood loss, and length of hospital stay, were assessed in both groups. Additionally, the QuickDASH score and visual analogue scale (VAS) were evaluated. Range of motion and grip strength assessment, imaging findings such as palmar inclination angle, ulnar declination angle, radius length, articular surface step, intra-articular space measurements were also examined along with any complications. RESULTS: The follow-up duration ranged from 0 to 24 months, with an average duration of (16.0±3.8) months. The CO external fixation exhibited significantly shorter time from injury to operation (2.4±3.3) d vs (7.4±3.7) d, shorter operation duration (56.27±15.23) min vs (74.10±5.26) min, lower blood loss (14.52±6.54) ml vs (32.32±10.03) ml, and reduced hospitalization days (14.04±3.24 )d vs (16.45±3.05) d compared to the internal fixation group (P<0.05). The QuickDASH score at 12 months post-operation was (8.21±1.64) in the CO external fixation group, while no significant difference was observed in the internal fixation group (7.04±3.64), P>0.05. There were no statistically significant differences in VAS between two groups at 6 weeks, as well as 1 and 3 months post-surgery (P>0.05). Additionally, there were no significant disparities observed in terms of range of motion and grip strength between two groups at the 2-year follow-up after the operation (P>0.05). After 12 months of surgery, the CO external fixation group exhibited a significantly smaller palmar inclination angle (17.90±2.18) ° vs (19.87±3.21) °, reduced articular surface step (0.11±0.03) mm vs (0.17±0.02) mm, and shorter radius length (8.16±1.11) mm compared to the internal fixation group (9.59±1.02) mm, P<0.05. The ulnar deviation angle and intra-articular space did not show any significant difference between two groups (P>0.05). The reduced fell within the allowable range between the CO external fixation group (23 out of 25 cases) and the internal fixation group (21 out of 23 cases) was not statistically significant (P=0.29). There was no significant difference in complications between the two groups(P>0.05). CONCLUSION Both the CO external fixation and open reduction with plate internal fixation demonstrate clinical efficacy in managing unstable distal radius fractures. The CO external fixation offers advantages in shorter injury-to-operation times, reduced intraoperative blood loss, and decreased surgical durations, while radial shortening is more effectively controlled by internal fixation.

The genome tagging project (GTP) plays a pivotal role in addressing a critical gap in the understanding of protein functions. Within this framework, we successfully generated a human influenza hemagglutinin-tagged sperm-specific protein 411 (HA-tagged Ssp411) mouse model. This model is instrumental in probing the expression and function of Ssp411. Our research revealed that Ssp411 is expressed in the round spermatids, elongating spermatids, elongated spermatids, and epididymal spermatozoa. The comprehensive examination of the distribution of Ssp411 in these germ cells offers new perspectives on its involvement in spermiogenesis. Nevertheless, rigorous further inquiry is imperative to elucidate the precise mechanistic underpinnings of these functions. Ssp411 is not detectable in metaphase II (MII) oocytes, zygotes, or 2-cell stage embryos, highlighting its intricate role in early embryonic development. These findings not only advance our understanding of the role of Ssp411 in reproductive physiology but also significantly contribute to the overarching goals of the GTP, fostering groundbreaking advancements in the fields of spermiogenesis and reproductive biology.

Sepsis is a lethal condition resulting from the host's dysregulated response, involving complex pathophysiological mechanisms, including the host's biphasic immune response and metabolic disturbances. Diagnosing and treating sepsis remain formidable challenges, with the absence of definitive biomarkers and effective therapeutic interventions to date. Animal models of sepsis are pivotal in unraveling the disease's pathogenesis and identifying potential treatments, playing a crucial role in enhancing our comprehension of its intrinsic nature. However, there is no animal model that can comprehensively and accurately simulate the complex pathophysiological process of human sepsis. This review discusses the widely used sepsis animal models, exploring their advantages and limitations in terms of pathogenesis, inflammatory response, pathophysiological changes, and organ dysfunction. It summarizes the application scenarios and latest research advancements of these models and provides an outlook on potential future improvements.

OBJECTIVE To identify the chemical components of Shenbai Jiedu Decoction(SBJDD),a traditional Chinese medi-cine(TCM)prescription clinically used for the treatment of colorectal adenoma(CRA),and explore the potential mechanism of SBJDD preventing and treating CRA carcinogenesis.METHODS An ultra-high performance liquid chromatography-time of flight-mass spectrometry(UPLC-Q-TOF-MS)method was established to detect the chemical components in the decoction of SBJDD and the plas-ma samples of rats after administration with SBJDD.Based on the network pharmacological method,SBJDD was screened for the poten-tial active ingredients at different stages of CRA carcinogenesis,and the mechanism of the anti-cancer effect of SBJDD was explored.In vitro experiments were also carried out to verify the mechanism of anti-colorectal cancer(CRC)action of SBJDD.RE-SULTS The detection data of UPLC-Q-TOF-MS showed that 152 components were found from SBJDD water extraction.41 chemical compounds were identified in plasma samples from rats administrated with SBJDD.Network pharmacology analysis indicated that during the CREI stage,the potential active ingredients in SBJDD,including epiberberine,and kushenol H,might affect target proteins such as PIK3CA,MAPK3 and PIK3CB.This,in turn,can influence signaling pathways like PI3K-AKT and Ras signaling pathways,and regulate biological processes like protein phosphorylation,and signal transduction.During the CRA stage,the potential active ingredi-ents from SBJDD,such as 3,7-dihydroxycoumarin,palmatine,and kushenol A,might affect target proteins such as AKT and EGFR.This can regulate the negative regulation of apoptotic process,and positive regulation of cell proliferation,and modify HIF-1,and Rap1 signaling pathways.During the progression of CRA carcinogenesis,potential active ingredients such as 3,7-dihydroxycouma-rin may interact with TP53,and impact the PI3K-AKT,and Thyroid hormone signaling pathways to regulate biological processes,in-cluding positive regulation of transcription from RNA polymerase Ⅱ promoter,and negative regulation of apoptotic process.In the CRC stage,core ingredients like p-coumaric acid may bind with proteins such as PRKCB.This binding may impact the signaling pathways that negatively affect EGFR tyrosine kinase inhibitor resistance,and PI3K-AKT signaling pathways.Additionally,it may regulate bio-logical processes,including negative regulation of apoptotic process,signal transduction,and protein phosphorylation.In vitro experi-ment results indicated that SBJDD inhibited the proliferation of HT29 cells and suppressed the expression of EGFR and PKC proteins.CONCLUSION The UPLC-Q-TOF-MS method is established to effectively separate the chemical constituents in SBJDD,which are mainly composed of alkaloids,organic acids and flavonoids components.Components from SBJDD dock with different targets during the carcinogenesis process of CRA and regulate cancer-related signaling pathways to exert therapeutic effects.
