Objective:To explore the feasibility and application value of an automated method for generation of surgical records for resection of benign soft tissue tumor based on dense video descriptions.Methods:The Transformer deep learning model was used to establish an automated surgical record generation system to analyze the surgical videos of 30 patients with benign soft tissue tumor who had been admitted to Department of Orthopedics, Xijing Hospital, Air Force Military Medical University from September 2021 to August 2023. The patient data were randomly divided into training sets, validation sets, and test sets in a ratio of 8∶1∶1. In the test sets, 7 evaluation indexes, BLEU-1, BLEU-2, BLEU-3, BLEU-4, Meteor, Rouge, and CIDEr, were used to evaluate the text quality of surgical records generated by the model. The text of surgical records was compared with the classical algorithm, dense video captioning with paralled decoding (PDVC) in the field of video-intensive description.Results:The automated surgical record generation system running in the test sets showed the following: BLEU-1, BLEU-2, BLEU-3, BLEU-4, Rouge, Meteor, and CIDEr were 16.80, 15.23, 13.01, 11.68, 16.01, 12.67 and 62.30, respectively. The operation of the classical algorithm PDVC showed the following: BLEU-1, BLEU-2, BLEU-3, BLEU-4, Rouge, Meteor, and CIDEr were 15.63, 14.17, 11.90, 10.45, 12.97, 11.99 and 53.64, respectively. The automated surgical record generation system resulted in significant improvements compared with PDVC in all evaluation indexes. The BLEU-4, Rouge, Meteor, and CIDEr were improved by 1.23, 3.04, 0.68 and 8.66, respectively, demonstrating that the system proposed can better capture the key data in the video to help generate more effective text records.Conclusion:As the automated surgical record generation system shows good performance in generating surgical records for resection of benign soft tissue tumor based on intensive video descriptions, it can be applied in clinical practice.

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Using chemoproteomic techniques, we first identified EIF2AK2, eEF1A1, PRDX3 and VPS4B as direct targets of berberine (BBR) for its synergistically anti-inflammatory effects. Of them, BBR has the strongest affinity with EIF2AK2 via two ionic bonds, and regulates several key inflammatory pathways through EIF2AK2, indicating the dominant role of EIF2AK2. Also, BBR could subtly inhibit the dimerization of EIF2AK2, rather than its enzyme activity, to selectively modulate its downstream pathways including JNK, NF-κB, AKT and NLRP3, with an advantage of good safety profile. In EIF2AK2 gene knockdown mice, the inhibitory IL-1β, IL-6, IL-18 and TNF-α secretion of BBR was obviously attenuated, confirming an EIF2AK2-dependent anti-inflammatory efficacy. The results highlight the BBR's network mechanism on anti-inflammatory effects in which EIF2AK2 is a key target, and inhibition of EIF2AK2 dimerization has a potential to be a therapeutic strategy against inflammation-related disorders.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.

Objective:To analyze the correlation between 1H-MRS in hippocampus and peripheral blood cytokines and T lymphocyte subsets in patients with temporal lobe epilepsy, and to explore the relationship between immune dysfunction and the degree of neuronal injury. Methods:Fifty patients with temporal lobe epilepsy were selected from Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021.Clinical data of all patients were collected and they were divided into two groups according to MRI results of epileptic sequence: abnormal hippocampal MRI group ( n=20) and normal hippocampal MRI group ( n=30). Bilateral 1H-MRS scanning of hippocampal and detection of T lymphocyte subsets and cytokines in peripheral blood during interictal period were performed in both groups. The levels of hippocampal metabolites NAA, NAA/(Cr+ Cho), T lymphocyte subsets and cytokines in peripheral blood of the two groups were compared.At the same time, the levels of NAA and NAA/ (Cr+ Cho) in the hippocampus on the abnormal side and the normal side in the abnormal hippocampal MRI group were compared within the group. Finally, the correlation between the levels of metabolites NAA, NAA/ (Cr+ Cho) in the hippocampus on the abnormal side obtained by 1H-MRS scanning and T lymphocyte subsets and cytokines in the abnormal group of MRI was analyzed. The data were statistically analyzed by SPSS 26.0 software. Independent sample t-test or Mann-Whitney U test was used for comparison between the two groups. Paired sample t-test was used for intra group comparison of different sides. Spearman correlation analysis was used to analyze the correlation between each index. Results:The NAA and NAA/(Cr+ Cho) values of the abnormal MRI group(normal side NAA: (1.22±0.37), NAA/(Cr+ Cho): (0.56±0.15). abnormal side NAA: (1.02±0.34), NAA/(Cr+ Cho): (0.48±0.13)) were significantly lower than those of the normal MRI group (NAA: (1.51±0.36), NAA/(Cr+ Cho): (0.73±0.19))(NAA: t=2.705, 4.800, both P<0 05; NAA/(Cr+ Cho): t=3.394, 4.914, both P<0 05). The values of NAA and NAA/(Cr+ Cho) in the abnormal side in the MRI abnormal group were significantly lower than those in the normal side( t=6.467, P<0 05). The levels of IL-1β(11.19(3.56, 20.98)pg/ml), IL-5 (3.12(1.86, 6.41)pg/ml), TNF-α(2.55(1.19, 8.28)pg/ml), CD4+ T lymphocytes((43.13±6.82)%) and Th/Ts((1.96±0.66)) in the hippocampal MRI abnormal group were significantly higher than those in normal MRI group (IL-1β: 3.27(1.63, 6.17)pg/ml, IL-5: 1.15(0.96, 2.96)pg/ml, TNF-α: 1.34(1.02, 2.36)pg/ml, CD4+ T: (38.01±7.21)%, Th/Ts: (1.48±0.53))( Z=-3.041, -2.516, -2.496, all P<0.05; t=2.511, 2.810, both P<0 05). The level of CD8+ T ((23.48±5.33)%) in peripheral blood of abnormal MRI group was significantly lower than that of normal group CD8+ T((27.18±6.08)%)( t=2.210, P<0.05). In the abnormal MRI group, the levels of NAA and NAA/ (Cr+ Cho) in the abnormal hippocampus were negatively correlated with the levels of IL-1β, IL-5 and TNF- α ( r=-0.612--0.463, all P<0.05), and positively correlated with CD8+ T lymphocytes ( r=0.537, 0.478, P<0.05). Conclusion:There is neuronal damage and dysfunction in the abnormal hippocampal region of patients with temporal lobe epilepsy with abnormal hippocampal formation, and the degree of neuronal damage is highly correlated with CD8+ T lymphocytes, IL-5, IL-1β and TNF-α in peripheral blood. The imbalance of interictal lymphocyte subsets and chronic inflammatory response may play an important role in the pathogenesis of epilepsy and neuronal injury .

The massive loss of oligodendrocytes caused by various pathological factors is a basic feature of many demyelinating diseases of the central nervous system (CNS). Based on a variety of studies, it is now well established that impairment of oligodendrocyte precursor cells (OPCs) to differentiate and remyelinate axons is a vital event in the failed treatment of demyelinating diseases. Recent evidence suggests that Foxg1 is essential for the proliferation of certain precursors and inhibits premature neurogenesis during brain development. To date, very little attention has been paid to the role of Foxg1 in the proliferation and differentiation of OPCs in demyelinating diseases of the CNS. Here, for the first time, we examined the effects of Foxg1 on demyelination and remyelination in the brain using a cuprizone (CPZ)-induced mouse model. In this work, 7-week-old Foxg1 conditional knockout and wild-type (WT) mice were fed a diet containing 0.2% CPZ w/w for 5 weeks, after which CPZ was withdrawn to enable remyelination. Our results demonstrated that, compared with WT mice, Foxg1-knockout mice exhibited not only alleviated demyelination but also accelerated remyelination of the demyelinated corpus callosum. Furthermore, we found that Foxg1 knockout decreased the proliferation of OPCs and accelerated their differentiation into mature oligodendrocytes both in vivo and in vitro. Wnt signaling plays a critical role in development and in a variety of diseases. GSK-3β, a key regulatory kinase in the Wnt pathway, regulates the ability of β-catenin to enter nuclei, where it activates the expression of Wnt target genes. We then used SB216763, a selective inhibitor of GSK-3β activity, to further demonstrate the regulatory mechanism by which Foxg1 affects OPCs in vitro. The results showed that SB216763 clearly inhibited the expression of GSK-3β, which abolished the effect of the proliferation and differentiation of OPCs caused by the knockdown of Foxg1. These results suggest that Foxg1 is involved in the proliferation and differentiation of OPCs through the Wnt signaling pathway. The present experimental results are some of the first to suggest that Foxg1 is a new therapeutic target for the treatment of demyelinating diseases of the CNS.

Objective: To investigate the efficacy and safety of Rivaroxaban for elderly patients with thrombotic diseases. Methods: This was a retrospective study.A total of 301 elderly patients taking Rivaroxaban from October 2012 to November 2017 at the Second Medical Center of the Chinese PLA General Hospital were consecutively selected.The ages ranged from 60 to 102 years, with an average age of(86.5±8.4)years.Anticoagulation regimens were developed based on comprehensive evaluation of indications, creatinine clearance, ischemia and bleeding risk.Patients were divided into a Rivaroxaban 2.5-5.0 mg/d group(n=72), a 10.0 mg/d group(n=205), and a 15.0-20.0 mg/d group(n=24). Hepatic function, renal function, and coagulation indexes were measured before and after the administration of Rivaroxaban.Fatal bleeding, cardiovascular deaths, all-cause deaths, non-fatal bleeding and thromboembolic events were recorded during the follow-up period. Results: The average dose of Rivaroxaban was(9.3±3.0)mg/d, and the minimum dose was 2.5 mg/d.The average follow-up time was(14.9± 13.9)months and the longest follow-up time was 48 months.One patient had intracranial bleeding.Twenty patients(6.6%)died with a cumulative incidence of 25.2%, three(1.0%)died of cardiac events, and 55.0% died of pneumonia and multiple organ failure.Forty patients(13.3%)had non-fatal hemorrhagic events with a cumulative incidence of 42.4%.Seven patients(2.3%)had thromboembolic events with a cumulative incidence of 16.0%, including 2 cases of non-fatal myocardial infarction, 3 cases of cerebral infarction and 2 cases of deep vein thrombosis.After treatment, levels of prothrombin time and fibrinogen significantly increased while levels of D-dimer significantly deceased(P<0.05). Conclusions Compared with previous reports, low-dose Rivaroxaban is safe and effective for elderly patients with thrombotic diseases.However, the risk of bleeding and ischemia should be comprehensively evaluated, and appropriate doses of Rivaroxaban should be selected individually.
