Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

In recent years, there have been frequent adverse reactions/events associated with traditional Chinese medicine(TCM), especially liver injury related to traditional non-toxic TCM, which requires adequate attention. Liver injury related to traditional non-toxic TCM is characterized by its sporadic and insidious nature and is influenced by various factors, making its detection and identification challenging. There is an urgent need to develop a strategy and method for early detection and recognition of traditional non-toxic TCM-related liver injury. This study was based on national adverse drug reaction monitoring center big data, integrating methodologies such as reporting odds ratio(ROR), network toxicology, and computational chemistry, so as to systematically research the risk signal identification and evaluation methods for TCM-related liver injury. The optimized ROR method was used to discover potential TCM with a risk of liver injury, and network toxicology and computational chemistry were used to identify potentially high-risk TCM. Additionally, typical clinical cases were analyzed for confirmation. An integrated strategy of "discovery via big data, identification via dry/wet method, confirmation via typical cases, and precise risk prevention and control" was developed to identify the risk of TCM-related liver injury. Corydalis Rhizoma was identified as a TCM with high risk, and its toxicity-related substances and potential toxicity mechanisms were analyzed. The results revealed that liver injury is associated with components such as tetrahydropalmatine and tetrahydroberberine, with potential mechanisms related to immune-inflammatory pathways such as the tumor necrosis factor signaling pathway, interleukin-17 signaling pathway, and Th17 cell differentiation. This paper innovatively integrated real-world evidence and computational toxicology methods, offering insights and technical support for establishing a risk discovery and identification strategy for TCM-related liver injury based on real-world big data, providing innovative ideas and strategies for guiding the safe and rational use of medication in clinical practices.

BACKGROUND: Blood glucose and serum albumin have been associated with cardiovascular disease prognosis, but the impact of admission-blood-glucose-to-albumin ratio (AAR) on adverse outcomes in critical ill coronary artery disease (CAD) patients was not investigated. METHODS: Patients diagnosed with CAD were non-consecutively selected from the MIMIC-IV database and categorized into quartiles based on their AAR. The primary outcome was 1-year mortality, and secondary endpoints were in-hospital mortality, acute kidney injury (AKI), and renal replacement therapy (RRT). A restricted cubic splines model and Cox proportional hazard models assessed the association between AAR and adverse outcomes in CAD patients. Kaplan-Meier survival analysis determined differences in endpoints across subgroups. RESULTS: A total of 8360 patients were included. There were 726 patients (8.7%) died in the hospital and 1944 patients (23%) died at 1 year. The incidence of AKI and RRT was 63% and 4.3%, respectively. High AAR was markedly associated with in-hospital mortality (HR = 1.587, P = 0.003), 1-year mortality (HR = 1.502, P < 0.001), AKI incidence (HR = 1.579, P < 0.001), and RRT (HR = 1.640, P < 0.016) in CAD patients in the completely adjusted Cox proportional hazard model. Kaplan-Meier survival analysis noted substantial differences in all endpoints based on AAR quartiles. Stratified analysis and interaction test demonstrated stable correlations between AAR and outcomes. CONCLUSIONS The results highlight that AAR may be a potential indicator for assessing in-hospital mortality, 1-year mortality, and adverse renal prognosis in critical CAD patients.

Objective To observe the potential mechanism of electroacupuncture regulating the erythropoietin-producing hepatocellular receptor B2/erythropoietin-producing hepatocellular receptor-interacting B2/big mitogen-activated protein kinase 1(EphB2/EphrinB2/BMK1) signaling pathway to improve neural damage in vascular dementia rats. Methods Eighty SD male adult rats were randomly divided into a sham surgery group, a model group, a non acupoint electroacupuncture group, a nimodipine group, and an electroacupuncture three needle group. The vascular dementia rat model was made by the modified Pulsinelli four vessel occlusion method. After grouping, the rats in each group were subjected to water maze test, HE staining, Nissl staining, and transmission electron microscopy(TEM) to observe the pathological changes in the hippocampal CA1 area, and the expression of EphB2 and BMK1 in the hippocampal CA1 area was detected by immunohistochemistry; Detection of EphB2 and BMK1 protein expression in rat hippocampal CA1 region was detected by Western blotting. Results Compared with the model group, the escape latency of vascular dementia rats treated with electroacupuncture and nimodipine decreased (P<0.05), while the number of crossing platforms significantly increased (P<0.05); The result of HE staining, Nissl staining and TEM showed that compared with the model group, the neurons in hippocampal CA1 area of rats in the EA Zhisanzhen group and nimodipine group were arranged orderly, and the morphology and structure of cells and organelle were complete; Immunohistochemical method and Western blotting showed that the expression of EphB2 and BMK1 in the CA1 region of hippocampus in the model group was significantly lower than that in the sham surgery group (P<0.05); Compared with the model group, the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the electroacupuncture Zhisanzhen group significantly increased (P<0.05), while the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the non acupoint electroacupuncture group was not statistically significant (P>0.05). Compared with the nimodipine group, the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the electroacupuncture Zhisanzhen group significantly increased (P<0.05). Conclusion Electroacupuncture may improve the damage of hippocampal neurons in vascular dementia rats by increasing the expression of EphB2 and BMK1 in the CA1 region of the hippocampus, thereby improving the learning and memory of vascular dementia rats.

Objective: To examine the radiomics model based on high-resolution T2WI and diffusion weighted imaging (DWI) in predicting microsatellite stability in patients with stage Ⅱ and Ⅲ rectal cancer. Methods: From February 2016 to October 2020, 175 patients with stage Ⅱ and Ⅲ rectal cancer who met the inclusion criteria were retrospectively collected. There were 119 males and 56 females, aged (63.9±9.4) years (range: 37 to 85 years), including 152 patients with microsatellite stability and 23 patients with microsatellite instability. All patients were randomly divided into the training group (n=123) and the validation group (n=52) with a ratio of 7∶3. The region of interest was labeled on the T2WI and DWI images of each patient using the ITK-SNAP software, and PyRadiomics was used to extract seven kinds of radiomics features. After removing redundant features and normalizing features, the least absolute shrinkage and selection operation were used for feature selection. One clinical model, three radiomics models and one clinical-radiomics model were constructed in the training group based on a support vector machine. The area under receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy were used to evaluate the performance of the models in the verification group. Results: Three clinical features (age, degree of tumor differentiation, and distance from the lower edge of the tumor to the anal edge) and six radiomics features (two DWI-related features and four T2WI-related features) most related to microsatellite status of rectal cancer patients were selected. The AUC of the clinical-radiomics model in the training group was 0.95. In the validation group, the AUC was 0.81, better than the clinical model (0.68, Z=0.71, P=0.04), and equivalent to the T2WI+DWI model (0.82, Z=0.21, P=0.83). Conclusions: Radiomic features based on preoperative T2WI and DWI were related to microsatellite stability in patients with stage Ⅱ and Ⅲ rectal cancer and showed a high classification efficiency. The model based on the features provided a noninvasive and convenient tool for preoperative determination of microsatellite stability in rectal cancer patients.

【Objective】 To investigate the feasibility of laparoscopic simple prostatectomy (LSP) in the treatment of large volume benign prostate hyperplasia (BPH). 【Methods】 Clinical and follow-up data of 30 patients with large volume BPH treated with LSP in our hospital during Feb.2019 and Dec.2021 were retrospectively analyzed. All patients underwent extraperitoneal LSP operation. The perioperative and 1-12 month postoperative follow-up data were analyzed. 【Results】 The average prostate volume was (92.4±38.9) mL, operation time (125±45) min, and weight of resected prostate (60.25±16.90) g. The hemoglobin decreased by (12.21±7.25) g/d after operation. No blood transfusion was needed. There was no need for bladder irrigation after operation in 21 cases (70%), and 9 cases (30%) had bladder irrigation time of (0.95±0.49) d. The postoperative catheter indwelling time was (6.92±2.51) d, and hospital stay (5.36±1.63) d. During the follow-up of (9.25±5.4) months, there was 1 case of postoperative intestinal obstruction (Clavien-Dindo grade II), 1 case of transient urinary incontinence (Clavien-Dindo grade I), and 1 case of delayed hematuria (Clavien-Dindo grade I). No urethral stricture occurred. The maximum urinary flow rate (Qmax), post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS) and quality of life (QoL) 3 months after operation were significantly improved compared with those before operation (P<0.05). There was no significant difference in sexual function before and after operation (P>0.05). 【Conclusion】 LSP is safe and effective in the treatment of large volume BPH. It has advantages of complete resection of glands, minor bleeding and short postoperative bladder irrigation time. However, it still needs to be confirmed by a prospective control study of large samples.

Objective: To investigate the response characteristics of patients with locally advanced/metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) treated with tislelizumab in combination with chemotherapy in the first line. Methods: Patients with nsq-NSCLC who achieved complete or partial remission after treatment with tislelizumab in combination with chemotherapy or chemotherapy alone in the RATIONALE 304 study, as assessed by an independent review board, were selected to analyze the response characteristics and safety profile of the responders. Time to response (TTR) was defined as the time from randomization to the achievement of first objective response. Depth of response (DpR) was defined as the maximum percentage of tumor shrinkage compared with the sum of the baseline target lesion length diameters. Results: As of January 23, 2020, 128 patients treated with tislelizumab in combination with chemotherapy achieved objective tumor response (responders), representing 57.4%(128/223) of the intention-to-treat population, with a TTR of 5.1 to 33.3 weeks and a median TTR of 7.9 weeks. Of the responders (128), 50.8%(65) achieved first remission at the first efficacy assessment (week 6), 31.3%(40) at the second efficacy assessment (week 12), and 18.0%(23) at the third and subsequent tumor assessments. The percentages of responders who achieved a depth of tumor response of 30% to <50%, 50% to <70% and 70% to 100% were 45.3%(58/128), 28.1%(36/128) and 26.6%(34/128), respectively, with median progression-free survival (PFS) of 9.0 months (95% CI: 7.7 to 9.9 months), 11.5 months (95% CI: 7.7 months to not reached) and not reached (95% CI: 11.8 months to not estimable), respectively. Tislelizumab plus chemotherapy were generally well tolerated in responders with similar safety profile to the overall safety population. Conclusion: Among responders to tislelizumab in combination with chemotherapy for nsq-NSCLC, 82.0%(105/128) achieves response within the first two tumor assessments (12 weeks) and 18.0%(23/128) achieves response at later (18 to 33 weeks) assessments, and there is a trend toward prolonged PFS in responders with deeper tumor response.

Objective:To investigate the effects of anterolateral wide pedicled double dynamic flap of the calf in repair of soft tissue defects of mid-and forefoot.Methods:From September 2015 to Septemler 2020, 15 cases with severe soft tissue defects of mid-and forefoot were repaired with the anterolateral wide pedicled double dynamic flap of the calf. There were 11 males and 4 females with an average age of 37(range, 22-53)years old. Of the 15 cases, the defects were caused by traffic accident in 6 cases and objects smash in 9 cases. Three cases were simple soft tissue defect, and 12 cases combined with fracture or dislocation and bone defect. The size of soft tissue defects ranged from 4 cm×5 cm to 7 cm×12 cm. All wounds of donor sites were repaired by skin grafting. All patients entered follow-ups at the outpatient clinic or through WeChat. The appearance of flaps and limb recovery were recorded after surgery.Results:All cases followed-up for 6-24 (mean, 16) months. Two days after surgery, 1 case had flap swelling and cyanosis, which was improved after pedicle suture removal and surface bloodletting. The pedicle of the flap was slightly bloated in 4 cases, and the texture and appearance were good in 11 cases. The ankle function of all cases recovered satisfactorily. The ranges of ankle motion were 15°-20° for dorsiflexion and 30°-40° for plantar flexion. The donor site healed well and all the skin grafts survived.Conclusion:The anterolateral wide pedicled double dynamic flap of the calf is one of the ideal flaps for repairing the soft tissue defects of the mid-and forefoot with reliable blood supply, sufficient venous return, simple operation and no require a vascular anastomosis.

SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.
