Objective:To investigate the diagnostic and prognostic value of systemic immune inflammatory index (SII) for severe traumatic brain injury secondary to acute lung injury (sTBI-ALI).Methods:A retrospective study was conducted on patients with severe traumatic brain injury admitted to the trauma center of the First Affiliated Hospital of Soochow University from January 2021 to November 2023. Patients received standard treatments including hemostasis and intracranial pressure management. Vital signs and blood routine data were collected upon admission. Patients were categorized into sTBI group and sTBI-ALI group based on established clinical diagnostic criteria for ALI to evaluate the diagnostic utility of SII. Subsequently, within the sTBI-ALI group, patients were stratified into survival and non-survival groups based on their 30-day outcomes to assess the prognostic value of SII.Results:A total of 260 sTBI patients were enrolled, of whom 113 developed ALI. Among the sTBI-ALI patients, 73 survived at 30 days. Compared to the sTBI group, the sTBI-ALI group exhibited significantly higher respiratory rates, heart rates, white blood cell counts, neutrophil counts, platelet counts, and SII levels (all P<0.05). Multivariate logistic regression analysis showed that SII index ( OR=1.003, 95% CI: 1.002-1.004, P<0.001) was an independent risk factor for ALI development in sTBI patients. The combined predictive model incorporating SII and heart rate yielded an AUC of 0.801 (95% CI: 0.740-0.862). The non-survival group had significantly higher neutrophil counts and SII levels, and significantly lower Glasgow Coma Scale scores than the survival group (all P<0.05). Multifactorial regression analysis indicated that SII index ( OR=1.002, P=0.004, 95% CI: 1.000-1.003) served as an independent risk factor for 30-day mortality in sTBI-ALI patients. The combined predictive model of SII and GCS achieved an AUC of 0.904 (95% CI: 0.848-0.960). Conclusions:SII demonstrates potential as a biomarker for predicting the development of ALI following sTBI. Furthermore, incorporating SII into predictive models significantly enhances the ability to forecast mortality risk in sTBI-ALI patients.

Objective:To investigate the clinical effect of intraarticular vancomycin on early periprosthetic joint infection (PJI) in knee arthroplasty and the incidence of postoperative complications.Methods:This is a retrospective cohort study. The clinical data of 1 867 patients who underwent primary knee arthroplasty at Department of Joint Surgery, the Affiliated Hospital of Qingdao University from April 2022 to June 2023 were retrospectively analysed, including total knee arthroplasty (TKA), robotic-assisted total knee arthroplasty (RA-TKA) and unicondylar knee arthroplasty (UKA). There were 687 males and 1 180 females, aged (68.0±11.2)years(range:45 to 87 years). Patients were divided into the vancomycin group and the control group according to whether or not intra-articular injection of 1 g of vancomycin powder dissolved in 30 ml of saline was performed after intraoperative joint capsule closure. In the vancomycin group, 925 patients were included, including 782 TKA, 27 RA-TKA and 116 UKA.In the control group, 942 patients were included, including 767 TKA, 99 RA-TKA and 76 UKA. Early PJI, wound complications, and vancomycin-related toxicity including acute renal collapse, ototoxicity, and allergic reactions were assessed within 3 months postoperatively. The data were compared using the independent sample t test, χ2 test, and Fisher's exact probability method, as appropriate. Major Extremity Trauma Research Consortium (METRC). Results:No PJI was found in all patients in the vancomycin group.Five cases (0.7%,5/767) of early PJI were found in TKA patients in the control group, with a statistically significant difference ( P=0.030); 1 case of early PJI was found in each RA-TKA and UKA patients, with non-significant difference compared with vancomycin group (all P>0.05). Two cases (0.3%,2/782) of incisional complications were found in TKA patients in the vancomycin group, and 4 cases (0.5%, 4/767) of incisional complications were found in TKA patients in the control group, with non-significant difference( P=0.449); no incisional complication was found in RA-TKA patients in the vancomycin group, and 1 case (1.0%,1/99) of incisional complications were found in RA-TKA patients in the control group, the difference was not statistically significant ( P>0.05); no incisional complication was found in both groups of UKA patients.No vancomycin-related acute kidney injury, ototoxicity, or allergic reactions was observed in all patients. Conclusion:Intra-articular injection of 1 g of vancomycin suspension after arthrotomy closure during TKA maybe lower the risk of early PJI without increasing the risk of wound complication and vancomycin-associated systemic toxicity.

OBJECTIVETo deepen the understanding of clinical manifestations and treatment of patients with positive lupus anticoagulant (LAC).

METHODSThe clinical data of 2 patients were analyzed and related literature were reviewed.

RESULTSCase 1, a 31-year-old female, diagnosed as lupus anticoagulant positive, secondary to undifferentiated connective tissue disease, was presented with menorrhagia and thrombocytopenia. Anti-nuclear antibody (ANA) was positive 1:1000 (homogeneous type) with anti-double stranded DNA positive, and dRVVT LA1/LA2 was 3.4. Coagulation function was alleviated after treatment with glucocorticoid and total glucosides of paeony. Case 2, a 59-year-old female was presented with gingival bleeding, hematuria with the level of F II:C 13%. dRVVT LA1/LA2 was 2.0. Anti-nuclear antibody (ANA) was positive 1:1000 (type of cytoplasmic granule), anti-double stranded DNA was positive. The patient was diagnosed as hypoprothrombinemia-lupus anticoagulant syndrome (LAHS) and acquired coagulation factor deficiency. The signs of hemorrhage were alleviated after treatment with methylprednisolone 40 mg/day and cyclophosphamide, while the level of F II:C was below normal.

CONCLUSIONSymptoms of patients with positive LAC are variable. The diagnosis relies on history of disease and laboratory test. Currently, there is no standardized treatment. Cases of LAHS should be thoroughly investigated for any known causes and related disorder.

OBJECTIVETo explore the clinical value of immature platelet fraction (IPF), absolute immature platelet fraction (A- IPF) and thrombelastograph (TEG) on assessment of bleeding risk of immune thrombocytopenia (ITP).

METHODStwo hundred and seventy- one patients with ITP were assessed based on ITP-BAT bleeding grading system. IPF, A-IPF were determined in 271 patients ,TEG in 125 patients. The correlations between bleeding grades and IPF, A-IPF, variables of TEG in subgroups were analyzed by statistical method. The predictive value of IPF, A-IPF, and variables of TEG on bleeding risk of ITP patients was evaluated.

RESULTSThere were no significant differences in bleeding degree in all patients with different gender and disease stage (P>0.05). Mild bleeding rate in children was higher than that in adult (P<0.05). PLT inversely correlated with bleeding grade for the entire cohort (P<0.001). In all subjects, PLT< 30 × 10⁹/L and pediatric cohorts with PLT< 30 × 10⁹/L, PLT were negatively correlated with IPF (P<0.05), positive correlated with A-IPF (P<0.001) and the maximum amplitude (MA (P<0.05). Bleeding grades were significantly correlated with IPF, A-IPF, MA in all subjects and patients with PLT< 30 × 10⁹/L (P<0.001). IPF, A-IPF and MA did not correlate with bleeding grades in children with PLT< 30 × 10⁹/L (P>0.05). ROC curve analysis revealed IPF, A-IPF and MA had better predictive value (AUC 0.745, 0.744, 0.813, P<0.001). Multivariate analysis showed that IPF and MA were independence factors for predicting bleeding risk in ITP patients and comprehensive predictive value was higher (AUC 0.846, P<0.001) than single variable.

CONCLUSIONIPF, A-IPF and MA could accurately evaluate bleeding risk in ITP patients. It may be considered as reference index of the treatment and observation index of curative effect.

OBJECTIVETo analyze clinical and molecular characteristics of low-risk essential thrombocythemia (ET) in a large cohort of Chinese patients and to explore risk factors for major thrombosis and treatment strategies.

METHODSMedical records of patients with an initial diagnosis of ET from March 1982 to May 2012 in our hospital were retrospectively analyzed.

RESULTSA total of 604 low-risk ET patients were enrolled with a median follow-up of 49 months (range:0-338). 43(7.1%) patients experienced major thrombotic events. Cox proportional hazards regression revealed JAK2 V617F mutation (HR=2.279; P=0.035) and cardiovascular risk factors (CVF) (HR=2.541; P=0.006) to be risk factors for total thrombotic events, while only CVF (HR=2.633; P=0.008) was risk factor for arterial thrombosis. None of the evaluated factors was related to venous thrombosis. Patients with both JAK2 V617F mutation and CVF had a worse thrombosis- free survival than those with only one risk factor (P<0.05). In patients with JAK2 V617F or CVF alone, antiplatelet treatment (P=0.016) significantly decreased the risk of thrombosis, while those with both JAK2 V617F and CVF could benefit from cytoreductive agents (P=0.018).

CONCLUSIONChinese low-risk ET patients have a lower risk of thrombosis than Caucasian low-risk ET patients. JAK2 V617F mutation and CVF are the most significant risk factors for thrombosis. Existence of both risk factors further increases the thrombotic risk. Treatment strategies on low-risk ET patients should be made based on presence or absence of risk factors.
