Ischemic stroke(IS) is a complex pathological process involving multiple cellular and molecular mechanisms and it is characterized by high mortality, high disability, and high recurrence. In recent years, the incidence of IS in China has been increasing year by year, and it has a trend of occurring in increasingly young individuals. Herb pairs are the smallest unit of traditional Chinese medicine(TCM) compatibility and an important part of TCM compounding, and the research on them is of great significance in guiding the clinical medication. Pharmacological studies have confirmed that certain herb pairs can exert anti-ischemic effects through various pathways such as reducing inflammation, alleviating oxidative stress, protecting the nervous system, and promoting neovascularization. By reviewing the relevant articles in the past decade, this paper probes into the combination rules, modern experimental studies, and combination ratios of the commonly used herb pairs from the etiology and pathogenesis of IS and summarizes 18 commonly used and deeply studied herb pairs, with a view to providing reference for the application, research, and development of clinical medicines.

PURPOSE: Intertrochanteric fractures undergoing proximal femoral nail antirotation (PFNA) surgery are associated with significant hidden blood loss. This study aimed to explore whether intramedullary administration of tranexamic acid (TXA) can reduce bleeding in PFNA surgery for intertrochanteric fractures in elderly individuals. METHODS: A randomized controlled trial was conducted from January 2019 to December 2022. Patients aged over 60 years with intertrochanteric fractures who underwent intramedullary fixation surgery with PFNA were eligible for inclusion and grouped according to random numbers. A total of 249 patients were initially enrolled, of which 83 were randomly allocated to the TXA group and 82 were allocated to the saline group. The TXA group received intramedullary perfusion of TXA after the bone marrow was reamed. The primary outcomes were total peri-operative blood loss and post-operative transfusion rate. The occurrence of adverse events was also recorded. Continuous data was analyzed by unpaired t-test or Mann-Whitney U test, and categorical data was analyzed by Pearson Chi-square test. RESULTS: The total peri-operative blood loss (mL) in the TXA group was significantly lower than that in the saline group (577.23 ± 358.02 vs. 716.89 ± 420.30, p = 0.031). The post-operative transfusion rate was 30.67% in the TXA group and 47.95% in the saline group (p = 0.031). The extent of post-operative deep venous thrombosis and the 3-month mortality rate were similar between the 2 groups. CONCLUSION We observed that intramedullary administration of TXA in PFNA surgery for intertrochanteric fractures in elderly individuals resulted in less peri-operative blood loss and decreased transfusion rate, without any adverse effects, and is, thus, recommended.

OBJECTIVE: To assess the cardioprotective effect and impact of Qishen Granules (QSG) on different ischemic areas of the myocardium in heart failure (HF) rats by evaluating its metabolic pattern, substrate utilization, and mechanistic modulation. METHODS: In vivo, echocardiography and histology were used to assess rat cardiac function; positron emission tomography was performed to assess the abundance of glucose metabolism in the ischemic border and remote areas of the heart; fatty acid metabolism and ATP production levels were assessed by hematologic and biochemical analyses. The above experiments evaluated the cardioprotective effect of QSG on left anterior descending ligation-induced HF in rats and the mode of energy metabolism modulation. In vitro, a hypoxia-induced H9C2 model was established, mitochondrial damage was evaluated by flow cytometry, and nuclear translocation of hypoxia-inducible factor-1 α (HIF-1 α) was observed by immunofluorescence to assess the mechanism of energy metabolism regulation by QSG in hypoxic and normoxia conditions. RESULTS: QSG regulated the pattern of glucose and fatty acid metabolism in the border and remote areas of the heart via the HIF-1 α pathway, and improved cardiac function in HF rats. Specifically, QSG promoted HIF-1 α expression and entry into the nucleus at high levels of hypoxia (P<0.05), thereby promoting increased compensatory glucose metabolism; while reducing nuclear accumulation of HIF-1 α at relatively low levels of hypoxia (P<0.05), promoting the increased lipid metabolism. CONCLUSIONS QSG regulates the protein stability of HIF-1 α, thereby coordinating energy supply balance between the ischemic border and remote areas of the myocardium. This alleviates the energy metabolism disorder caused by ischemic injury.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

OBJECTIVE: The relationship between fish consumption and stroke is inconsistent, and it is uncertain whether this association varies across predicted stroke risks. METHODS: A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted. A standardized questionnaire was used to collect data on fish consumption. Participants were stratified into low- and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores. Hazard ratios ( HRs) and 95% confidence intervals ( CIs) were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). RESULTS: During 703,869 person-years of follow-up, 2,773 incident stroke events were identified. Higher fish consumption was associated with a lower risk of stroke, particularly among moderate-to-high-risk individuals ( HR = 0.53, 95% CI: 0.47-0.60) than among low-risk individuals ( HR = 0.64, 95% CI: 0.49-0.85). A significant additive interaction between fish consumption and predicted stroke risk was observed (RERI = 4.08, 95% CI: 2.80-5.36; SI = 1.64, 95% CI: 1.42-1.89; AP = 0.36, 95% CI: 0.28-0.43). CONCLUSION Higher fish consumption was associated with a lower risk of stroke, and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

BackgroundStudents in secondary vocational health school are at the age of puberty and prone to depressive symptoms. Peer victimization and social media addiction are found to be crucial in influencing the development of depression， and positive mental health has been proven to alleviate depressive symptoms， whereas there remains a striking lack of research on the mediating role of positive mental health and social media addiction in the relationship between peer victimization and depressive symptoms among secondary vocational health school students. ObjectiveTo explore the relationship between peer victimization and depressive symptoms and investigate the mediating role of positive mental health and social media addiction， so as to provide references for the prevention of depression among secondary vocational health school students. MethodsFrom October to December 2020， a cluster sampling framework was utilized to recruit 7 307 students from a secondary vocational health school in Luzhou City， Sichuan Province. Assessments were performed using Multidimensional Peer Victimization Scale （MPVS）， Warwick-Edinburgh Mental Well-being Scale （WEMWBS）， Bergen Social Media Addiction Scale （BSMAS） and Patient Health Questionnaire Depression Scale-9 item （PHQ-9）. Spearman correlation analysis was calculated to determine correlations between scores of scales， Process 4.0 was employed to test the mediation effect， and the bias-corrected Bootstrap procedure was used to test the significance of the mediation effect. ResultsA total of 7 044 （96.40%） valid questionnaires were collected. And 4 391（62.34%）students were found to have depressive symptoms. Correlation analysis revealed that PHQ-9 score was positively correlated with BSMAS score and MPVS score （r=0.404， 0.506， P<0.01）. WEMWBS score was negatively correlated with PHQ-9 score， BSMAS score and MPVS score （r=-0.587， -0.259， -0.358， P<0.01）. BSMAS score was positively correlated with MPVS score （r=0.328， P<0.01）. Positive mental health played a mediating role in the relationship between peer victimization and depressive symptoms， with an indirect effect value of 0.130 （95% CI： 0.119~0.141）， accounting for 30.81% of the total effect. Social media addiction also mediated the relationship between peer victimization and depressive symptoms， with an indirect effect value of 0.052 （95% CI： 0.045~0.059）， accounting for 12.34% of the total effect. Positive mental health and social media addiction exhibited a chained mediation effect on the relationship between peer victimization and depressive symptoms， with an indirect effect value of 0.012 （95% CI： 0.010~0.014） and accounting for 2.84% of the total effect. ConclusionPeer victimization can affect the presence of depressive symptoms among secondary vocational health school students both directly and indirectly through either separate or chained mediation of positive mental health and social media addiction.

Objective:To investigate the clinical distribution and diagnostic value of anti-total phospholipid-antibodies(aTPL) patients with in antiphospholipid syndrome(APS).Methods:We collected the clinical data and laboratory test results of patients diagnosed with APS, systemic lupus erythematosus, Sj?gren′s syndrome, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, mixed connective tissue disease, and adult Still′s disease in Peking University People′s Hospital from February 2009 to October 2017. A total of 335 cases were studied, of which 163 were APS patients, 122 were disease control(DC) and 50 were health control(HC). Enzyme-linked immunosorbent assay(ELISA) was used to measure aTPL, anti-cardiolipin antibody (aCL), and anti-beta-2-glycoprotein Ⅰ antibody (aβ 2GPⅠ). The Chi-square test was used to compare the differences between groups. Results:The prevalence of aTPL in APS, DC and HC were 39.9%, 3.3%and 2.0% respectively. The sensitivity and specificity were 39.9%, 97.1%. The proportion of thrombosis[75.4%(49/65) vs. 51.0%(50/98), χ2=9.73, P=0.002] and arterial thrombosis[49.2%(32/65) vs. 25.5%(25/98), χ2=9.67, P=0.002] was significantly higher in the aTPL positive group than that of the negative group. In aTPL positive group, the positive rate of aCL[84.6%(55/65) vs.29.6%(29/98), χ2=47.37, P<0.001], aβ 2GPⅠ[83.1%(54/65) vs.37.8%(37/98), χ2=32.55, P<0.001] and LA[61.5%(40/65) vs. 42.9%(42/98), χ2=5.46, P=0.020] was significantly higher than that of negative group.The area under ROC curve (95% CI) of aTPL [0.694(0.636, 0.751)] was slightly higher than that of aCL [0.668(0.610, 0.726)], but lower than that of aβ 2GPⅠ [0.746(0.694, 0.799)]. Conclusion:aTPL exhibits a strong correlation with thrombosis in patients with APS, particularly arterial thrombosis, and demonstrates high specificity, which can assist in the diagnosis of seronegative APS.

Objective:To investigate the current status of vascular access team building and analysis its related factors in hemodialysis centers in China.Methods:The study was a cross-sectional survey. Using a convenience sampling method, a questionnaire was designed to investigate the clinical practice of vascular access teams in 527 hemodialysis centers in China from March to April 2022. The related factors of the formation of vascular access teams and the setting up of vascular access coordinators (VAC) were analyzed by multivariate logistic regression method.Results:A total of 506 valid questionnaires were recovered, with a recovery rate of 96.02%. There were 247 (48.81%) and 193 (38.14%) hemodialysis centers respectively across China that had built vascular access teams and set up VAC. Hemodialysis centers with more than 10 years of practice had higher rate of implementation than those in hemodialysis centers with practice years less or equal than 10 years in developing standardized procedures for vascular access management ( χ 2=8.288, P=0.004), holding continuous quality improvement meetings on vascular access ( χ 2=8.210, P=0.004), establishing vascular access teams ( χ 2=33.805, P<0.001) and setting up vascular access coordinators ( χ 2=16.038, P<0.001), and the difference was statistically significant. The results of multivariate logistic regression analysis showed that the number of dialysis machines ( OR=2.221, 95% CI 1.118-4.415, P=0.023), the number of patients on dialysis( OR=2.946, 95% CI 1.375-6.310, P=0.005), and the establishment of VAC positions ( OR=9.463, 95% CI 5.307-16.874, P<0.001), and the standardized vascular access management process ( OR=3.383, 95% CI 2.012-5.687, P<0.001) were the related factors of vascular access team building. The related factors of setting up a VAC position in hemodialysis center were opening vascular access clinic ( OR=2.704,95% CI 1.382-5.290, P=0.004), the formation of a vascular access team ( OR=9.464, 95% CI 5.312-16.860, P<0.001), and constructing standardized procedures for vascular access management ( OR=3.663, 95% CI 2.243-5.982, P<0.001). Conclusion:The implementation rates of vascular access team and VAC position in hemodialysis centers were 48.81% and 38.14%, respectively. The number of dialysis machines, the number of patients on dialysis, the standardized procedures for vascular access management, the vascular access clinic, the vascular access team, and the VAC position were the relevant factors of the team building for vascular access.
