OBJECTIVE: To investigate the predictive value of circulating free DNA (cfDNA) combined with interleukin 10 (IL-10) in predicting central nervous system infiltration (CNSI) in diffuse large B-cell lymphoma (DLBCL). METHODS: The clinical data of 63 patients with DLBCL in our hospital from May 2021 to April 2023 were retrospectively analyzed. The 63 patients were divided into CNSI group (15 cases) and non-CNSI group (48 cases) base on whether CNSI occurred. The age, sex, Ann Arbor stage, ECOG score, IPI risk, CNS-IPI risk, number of extranodal sites involved, bone marrow involvement, hypertrophic disease, B symptoms, source cells, glucose quantification, Pandy test, cerebrospinal fluid (CSF) chlorine, CSF nucleated cell count, CSF protein, peripheral blood cfDNA, and IL-10 status were compared between the two groups. The correlation between cfDNA, IL-10 in peripheral blood and CSF protein was analyzed by Pearson correlation analysis. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of peripheral blood cfDNA and IL-10 on secondary CNSI in DLBCL patients. The last follow-up was on November 30, 2023. Kaplan-Meier method was used to calculate the time of secondary CNSI in the non-CNSI group. RESULTS: The IPI risk, CNS-IPI risk, number of extranodal sites involved, and CSF protein in the CNSI group were significantly higher than those in the non-CNSI group (all P <0.05). The levels of cfDNA and IL-10 in peripheral blood of CNSI group were significantly higher than those of non-CNSI group (both P <0.01). cfDNA and IL-10 in peripheral blood were both positively correlated with CSF protein (r =0.402 4, 0.315 1). ROC curve analysis showed that peripheral blood cfDNA and IL-10 had certain predictive value for CNSI, and the area under the curve (AUC) was 0.829 and 0.742, respectively. The AUC of the combined detection was 0.910, with a sensitivity of 80.00% and a specificity of 93.70%. The diagnostic efficacy was significantly higher than that of the two prediction values alone. The median follow-up time was 20 (6-31) months. Non-CNSI patients were grouped based on peripheral blood cfDNA combined with IL-10 positive or negative pairs. The time of secondary CNSI in positive group was significantly shorter than that in negative group (P <0.05). CONCLUSION cfDNA and IL-10 in peripheral blood of DLBCL patients with CNSI are significantly increased, and the combined detection of cfDNA and IL-10 has good predictive value for CNSI.

Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.

Recent studies have indicated that the expression of ubiquitin-specific protease 51 (USP51), a novel deubiquitinating enzyme (DUB) that mediates protein degradation as part of the ubiquitin‒proteasome system (UPS), is associated with tumor progression and therapeutic resistance in multiple malignancies. However, the underlying mechanisms and signaling networks involved in USP51-mediated regulation of malignant phenotypes remain largely unknown. The present study provides evidence of USP51's functions as the prominent DUB in chemoresistant triple-negative breast cancer (TNBC) cells. At the molecular level, ectopic expression of USP51 stabilized the 78 kDa Glucose-Regulated Protein (GRP78) protein through deubiquitination, thereby increasing its expression and localization on the cell surface. Furthermore, the upregulation of cell surface GRP78 increased the activity of ATP binding cassette subfamily B member 1 (ABCB1), the main efflux pump of doxorubicin (DOX), ultimately decreasing its accumulation in TNBC cells and promoting the development of drug resistance both in vitro and in vivo. Clinically, we found significant correlations among USP51, GRP78, and ABCB1 expression in TNBC patients with chemoresistance. Elevated USP51, GRP78, and ABCB1 levels were also strongly associated with a poor patient prognosis. Importantly, we revealed an alternative intervention for specific pharmacological targeting of USP51 for TNBC cell chemosensitization. In conclusion, these findings collectively indicate that the USP51/GRP78/ABCB1 network is a key contributor to the malignant progression and chemotherapeutic resistance of TNBC cells, underscoring the pivotal role of USP51 as a novel therapeutic target for cancer management.

OBJECTIVE: Ulcerative colitis is closely associated with intestinal stem cell (ISC) loss and impaired intestinal mucus barrier. Sinisan (SNS), a compound Chinese herbal medicine, has a long history in the treatment of intestinal dysfunction, yet whether SNS can relieve acute experimental colitis by modulating ISC proliferation and secretory cell differentiation has not been studied. Our study tested the effect of SNS against acute colitis and focused on the mechanisms involving intestinal barrier recovery. METHODS: Network pharmacology analysis and blood entry component analysis of SNS were used to explore the underlying mechanism by which SNS affects the acute dextran sulfate sodium (DSS)-induced murine colitis model. RNA-sequencing was used to demonstrate the mechanism. Further, reverse transcription-quantitative polymerase chain reaction, immunofluorescence staining, and alcian blue and periodic acid-Schiff staining were performed in vivo and in the colonic organoids to investigate the cell lineage differentiation-related mechanism of SNS. Furthermore, potential active ingredients from SNS were predicted by network pharmacology analysis. RESULTS: SNS dramatically suppressed DSS-induced acute colonic inflammation in mice. RNA-sequencing analysis revealed downregulation of inflammation and apoptosis-related genes, and upregulation of lipid metabolism and proliferation-related genes, such as Irf7, Pparα, Clspn and Hspa5. Additionally, ISC renewal and intestinal secretory cell lineage commitment were significantly promoted by SNS both in vivo and in vitro in colonic organoids, leading to enhanced mucin expression. Furthermore, potential active ingredients from SNS that mediated inflammation, lipid metabolism, proliferation, apoptosis, stem cells and secretory cells were predicted using a network pharmacology approach. CONCLUSION Our study shed light on the underlying mechanism of SNS in attenuating acute colitis from the perspective of ISC renewal and secretory lineage cell differentiation, suggesting a of novel therapeutic strategy against colitis.

Objective To compare the role and importance of fibular fixation in tibiofibular fractures by Meta-analysis.Methods The literature related to the comparison of the efficacy of fixation of the fibula with or without fixation on the treatment of tibiofibular fractures was searched through the databases of China Knowledge Network,Wipu,Wanfang,The Cochrane Li-brary,Web of science and Pubmed,and statistical analysis was performed using RevMan 5.3 software.The rates of malrotation,rotational deformity,internal/external deformity,anterior/posterior deformity,non-union,infection,secondary surgery and op-erative time were compared between the fibula fixation and non-fixation groups.Results A total of 11 publications were includ-ed,six randomised controlled trials and five case-control trials,eight of which were of high quality.A total of 813 cases were in-cluded,of which 383 were treated with fibula fixation and 430 with unfixed fibulae.Meta-analysis results showed that fixation of the fibulae in the treatment of tibiofibular fractures reduced the rates of postoperative rotational deformity[RR=0.22,95％CI(0.10,0.45),P＜0.000 1]and internal/external deformity[RR=0.34,95％CI(0.14,0.84),P=0.02]and promoted fracture heal-ing[RR=0.76,95％CI(0.58,0.99),P=0.04].In contrast,the rates of poor reduction[RR=0.48,95％CI(0.10,2.33),P=0.36],anterior/posterior deformity[RR=1.50,95％CI(0.76,2.96),P=0.24],infection[RR=1.43,95％CI(0.76,2.72),P=0.27],sec-ondary surgery[RR=1.32,95％CI(0.82,2.11),P=0.25],and operative time[MD=10.21,95％CI(-17.79,38.21),P=0.47]were not statistically significant(P＞0.05)for comparison.Conclusion Simultaneous fixation of the tibia and fibula is clinically more effective in the treatment of tibiofibular fractures.

Objective To make an epidemiological investigation on traditional Chinese medicine(TCM)dampness syndrome manifestations in the population at risk of cerebrovascular diseases in Guangdong area.Methods A cross-sectional study was conducted to analyze the clinical data related to the risk of cerebrovascular diseases in 330 Guangdong permanent residents.The diagnosis of dampness syndrome,quantitative scoring of dampness syndrome and rating of the risk of stroke were performed for the investigation of the distribution pattern of dampness syndrome and its influencing factors.Results(1)A total of 306(92.73%)study subjects were diagnosed as dampness syndrome.The percentage of dampness syndrome in the risk group was 93.82%(258/275),which was slightly higher than that of the healthy group(48/55,87.27%),but the difference was not statistically significant(χ2 = 2.91,P = 0.112).The quantitative score of dampness syndrome in the risk group was higher than that of the healthy group,and the difference was statistically significance(Z =-2.24,P = 0.025).(2)Among the study subjects at risk of cerebrovascular disease,evaluation time(χ2 = 26.11,P = 0.001),stroke risk grading(χ2= 8.85,P = 0.031),and history of stroke or transient ischemic attack(TIA)(χ2 = 9.28,P = 0.015)were the factors influencing the grading of dampness syndrome in the population at risk of cerebrovascular disease.Conclusion Dampness syndrome is the common TCM syndrome in the population of Guangdong area.The manifestations of dampness syndrome are more obvious in the population with risk factors of cerebrovascular disease,especially in the population at high risk of stroke,and in the population with a history of stroke or TIA.The assessment and intervention of dampness syndrome should be taken into account for future project of stroke prevention in Guangdong.

Objective To investigate the long-term incidence of in-stent stenosis(ISS)in patients with intracranial aneurysms receiving pipeline embolization device(PED)who showed no ISS at short-to-medium term follow-up examination.Methods The clinical data of patients,who received PED treatment at the Department of Neurointervention,First Affiliated Hospital of Zhengzhou University of China between April 2015 and June 2022,were retrospectively collected.The patients with intracranial aneurysms,who showed no ISS at the initial follow-up with DS A and completed＞12 months long-term follow-up check after treatment at the same hospital,were screened out,and their relevant clinical data and imaging materials were collected.The incidence of ISS occurring in postoperative＞12 months long-term follow-up was calculated.The ISS was defined as a＞25％lumen loss of the parent artery when compared with its lumen size measured immediately after PED implantation.Results A total of 57 patients with 61 aneurysms were enrolled in this study,and a total of 68 PEDs were implanted.Forty-one(67.21％)aneurysms were treated by PED implantation only,and 20(32.79％)aneurysms by PED plus spring coils.The median initial follow-up time was 184.0 days(119.0,212.5).At postoperative＞12 months long-term follow-up visit,DSA was employed for 35(57.38％)aneurysms,CTA was adopted for 22(36.07％)aneurysms,and 3D-SPACE sequence MR scan was performed in 4(6.56％)aneurysms.The median follow-up time was 538.0 days(407.5,678.0),and the incidence of ISS was 0％.No ISS-related neurological symptoms occurred in all patients.Conclusion In treating intracranial aneurysms with PED,the postoperative incidence of ISS is low.No ISS is found during the short-term follow-up period,and long-term follow-up results tend to indicate that no ISS events have occurred.

Objective To investigate the latent classes of mental workload and related factors among cardiovascular nurses.Methods A convenience sample of 664 cardiovascular nurses were surveyed from Jun to Jul 2023.General information questionnaire,the Nurse Workload Index Scale and the Nursing Interruption Event Scale were conducted in the investigation.Latent class analysis and multiple Logistic regression analysis were employed to analyze the latent classes of nurses'mental workload and its related factors.Results Two latent classes were identified,named low mental workload group(25.90%)and a high mental workload group(74.10%).Multiple Logistic regression analysis revealed that educational qualifications(OR=1.641,95%CI:1.036-2.598),nursing interruption event scores(OR=1.060,95%CI:1.044-1.076),and the region of nurses(OR=0.688,95%CI:0.542-0.874)were the influencing factors for cardiovascular nurses'mental workload.Conclusion There are obvious categorical characteristics of cardiovascular nurses'mental workload,nurses with higher education,frequent interruption events,and from the eastern region have higher mental workload.Nursing managers need to focus on human resource allocation and optimize processes to reduce the occurrence of nursing interruptions.

Objective:To explore the characteristics and changes of cardiac injury with age in Duchenne muscular dystrophy (DMD) and its clinical significance.Methods:A prospective cohort study was conducted. The 215 patients diagnosed with DMD in West China Second Hospital from January 2019 to November 2022 and aged from 6 to 18 years were enrolled. Their clinical data, myocardial injury markers, routine electrocardiogram, cardiac magnetic resonance (CMR) and echocardiography were collected. The patients were divided into five age groups: 6-<8, 8-<10, 10-<12, 12-<14 and 14-18 years of age, and matched with healthy boys respectively. Independent sample t test or Mann-Whitney U test was used to compare the clinical data and CMR indexes between DMD patients and controls in all age subgroups, and to compare the value of left ventricular ejection fraction (LVEF) measured by echocardiography and CMR in each subgroup of DMD patitents. Pearson correlation analysis or Spearman correlation analysis was used to explore the relation between the CMR indexes and age in DMD patients. Results:A total of 215 patients with DMD (all male) and 122 healthy boys were included in the study. There were 75 DMD patients and 23 controls in 6-<8 years of age group, 77 DMD and 28 controls in 8-<10 years of age group, 39 DMD and 23 controls in 10-<12 years of age group, 10 DMD and 31 controls in the 12-<14 years of age group, and 14 DMD and 17 controls in 14-18 years of age group. In the DMD patients, the older the age, the lower the levels of creatine kinase (CK) and creatine kinase isoenzyme (CK-MB). In the 6-<8 years of age group, the CK level was 10 760 (7 800, 15 757) U/L, while in the group of 14-18 years of age, it was 2 369 (1 480, 6 944) U/L. As for CK-MB, it was (189±17) μg/L in the 6-<8 years of age group and (62±16) μg/L in the 14-18 years of age group. Cardiac troponin I remained unchanged in <12 years of age groups, but significantly increased in 12-<14 years of age group, reaching the highest value of 0.112 (0.006, 0.085) μg/L. In the DMD patients, the older the age, the higher the proportion of abnormal electrocardiogram (ECG). In the 6-<8 years of age group, the proportion is 29.3% (22/75), while in the 14-18 years of age group, it was 10/14. Correlation analysis showed that the left ventricular end-diastolic volume index was positively related with age ( r=0.18, P=0.015), and the left ventricular stroke volume index and cardiac output index were negatively related with age ( r=-0.34 and -0.31, respectively, both P<0.001). In the DMD patients, the older the age, the lower LVEF, with the LVEF decreasing to (49.3±3.1)% in the 14-18 years of age group. The LVEF of DMD cases was significantly lower than that of controls in the age subgroups of 8-<10, 10-<12, 12-<14 and 14-18 years of age groups ((57.9±5.2) % vs. (63.6±0.8)%, 60.7% (55.9%, 61.9%) vs. 63.7% (60.2%, 66.0%), 57.1% (51.8%, 63.4%) vs. 62.1 % (59.5%, 64.5)%, (49.3±3.1) % vs. (61.6±1.3)%, respectively; all P<0.01). In the DMD patients, the older the age, the higher the proportion of positive late gadolinium enhancement (LGE). In the 6-<8 years of age group, it was 22% (11/51), in the 12-<14 years of age group, it was 13/14, and in the 14-18 years of age group, all DMD showed positive LGE. The value of LVEF of DMD cases measured by echocardiography was significantly higher than that measured by CMR in 6-<8 years of age group and 8-<10 years of age group (63.2% (60.1%, 66.4%) vs. 59.1 % (55.4%, 62.9%), and (62.8±5.2) % vs. (57.9±5.2)%, all P<0.001). Conclusion:DMD patients develop cardiac injury in the early stage of the disease, and the incidence of cardiac damage gradually increases with both age and the progression of disease.
