Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

BACKGROUND: The FAVOR (Comparison of Quantitative Flow Ratio Guided and Angiography Guided Percutaneous Intervention in Patients with Coronary Artery Disease) III China trial demonstrated that percutaneous coronary intervention (PCI) lesion selection using quantitative flow ratio (QFR) measurement, a novel angiography-based approach for estimating fractional flow reserve, improved two-year clinical outcomes compared with standard angiography guidance. This study aimed to assess the cost-effectiveness of QFR-guided PCI from the perspective of the current Chinese healthcare system. METHODS: This study is a pre-specified analysis of the FAVOR III China trial, which included 3825 patients randomized between December 25, 2018, and January 19, 2020, from 26 centers in China. Patients with stable or unstable angina pectoris or those ≥72 hours post-myocardial infarction who had at least one lesion with a diameter stenosis between 50% and 90% in a coronary artery with a ≥2.5 mm reference vessel diameter by visual assessment were randomized to a QFR-guided strategy or an angiography-guided strategy with 1:1 ratio. During the two-year follow-up, data were collected on clinical outcomes, quality-adjusted life-years (QALYs), estimated costs of index procedure hospitalization, outpatient cardiovascular medication use, and rehospitalization due to major adverse cardiac and cerebrovascular events (MACCE). The primary analysis calculated the incremental cost-effectiveness ratio (ICER) as the cost per MACCE avoided. An ICER of ¥10,000/MACCE event avoided was considered economically attractive in China. RESULTS: At two years, the QFR-guided group demonstrated a reduced rate of MACCE compared to the angiography-guided group (10.8% vs . 14.7%, P <0.01). Total two-year costs were similar between the groups (¥50,803 ± 21,121 vs . ¥50,685 ± 23,495, P = 0.87). The ICER for the QFR-guided strategy was ¥3055 per MACCE avoided, and the probability of QFR being economically attractive was 64% at a willingness-to-pay threshold of ¥10,000/MACCE avoided. Sensitivity analysis showed that QFR-guided PCI would become cost-saving if the cost of QFR were below ¥3682 (current cost: ¥3800). Cost-utility analysis yielded an ICER of ¥56,163 per QALY gained, with a 53% probability of being cost-effective at a willingness-to-pay threshold of ¥85,000 per QALY gained. CONCLUSION: In patients undergoing PCI, a QFR-guided strategy appears economically attractive compared to angiographic guidance from the perspective of the Chinese healthcare system.

Objective: To investigate the short-term outcome of patients with acute myocardial infarction complicating cardiogenic shock due to left main disease. Methods: A total of 24 patients with acute myocardial infarction complicating cardiogenic shock due to left main artery disease hospitalized in Fuwai hospital from June 2012 to May 2018 were included. The clinical data were analyzed,and the patients were divided into survivor group (11 cases) and death group (13 cases) according to survival status at 28 days post the diagnosis of shock. The patients were further divided into thrombolysis in myocardial infarction(TIMI) flow grade 0-2 group (11 cases) and TIMI flow grade 3 group (13 cases) according to TIMI flow grade after the procedure. The patients were then divided into non-three-vessel lesions group (14 cases) and three-vessel lesions group (10 cases) according to coronary angiography results. Results: Compared with survivor group, patients in death group presented with lower worst systolic blood pressure within 24 hours after admission (50(48, 70) mmHg (1 mmHg=0.133 kPa) vs. 73(70, 80) mmHg, P<0.01), lower worst diastolic blood pressure with in 24 hours after admission ((33.5±12.4) mmHg vs. (48.9±9.4) mmHg, P<0.01), higher respiratory rates ((27.3±2.5) times/min vs. (21.5±4.0) times/min, P<0.01), less 24 hours urine output ((422±266) ml vs. (1 680±863) ml, P<0.01), lower platelet counts ((161.9±81.9)×10⁹/L vs. (241.6±94.0)×10⁹/L, P=0.03), higher serum creatinine ((250.0±36.8) μmol/L vs. (132.7±34.2) μmol/L, P<0.01), higher alanine aminotransferase (288(76,846) IU/ml vs. 81(42, 109) IU/ml, P=0.04), lower artery pH (7.11±0.17 vs. 7.39±0.09, P<0.01), higher lactic acid ((10.29±3.62) mmol/L vs. (4.21±2.85) mmol/L, P<0.01), higher incidence of invasive ventilation (7/13 vs. 2/11, P=0.02), higher scores of acute physiology and chronic health evaluation (APACHE) Ⅱ (35.4±6.8 vs. 18.7±1.7, P<0.01) and simplified acute physiology score (SAPS) Ⅱ (73.5±17.4 vs. 47.0±4.3, P<0.01), and higher incidence of target vessel TIMI flow grade 0-2 (10/13 vs. 1/11, P<0.01). Kaplan-Meier survival curve analysis showed that survival rate at 28 days post the diagnosis of shock in TIMI flow grade 3 group was higher than that in TIMI flow grade 0-2 group (76.9% vs. 9.1%, log-rank test, P<0.01), and mortality rate was similar at 28 days post the diagnosis of shock between non-three-vessel lesions group and three-vessel lesions group (35.7% vs. 60.0%, log-rank test, P=0.14). Multivariate logistic regression analysis showed that compared with TIMI flow grade 0-2 group, the OR value of death at 28 days post the diagnosis of shock in TIMI flow grade 3 patients with acute myocardial infarction complicating cardiogenic shock due to left main disease was 0.030(95%CI 0.003-0.340, P<0.01). Conclusion Short-term outcomeof patients with acute myocardial infarction complicating cardiogenic shock due to left main disease remains poor, and final flow of TIMI grade 3 is confirmed as independent protective factor of death at 28 days post the diagnosis of shock in these patients.

Objective: To compare predictive value of the current 7 scoring systems and CADILLAC-plus scoring system for risk of short-term deathin patients with acute myocardial infarction complicating cardiogenic shock. Methods: A total of 126 acute myocardial infarction patients complicating cardiogenic shock hospitalized in Fuwai hospital from June 2014 to January 2018 were enrolled in this study, the clinical data were retrospectively analyzed. The patients were divided into survival group(49 cases) and death group(77 cases) according to survival or not at 28 days after diagnosis of cardiogenic shock.The scores of APACHE Ⅱ,APACHE Ⅲ,SAPS Ⅱ,PAMI, TIMI-STEMI,TIMI-NSTEMI,and CADILLAC were calculated within 24 hours in coronary care unit (CCU),and scores of CADILLAC-plus, which is an improved score derived from CADILLAC, was also calculated.

Objective: To confirmed the polymorphisms of HLA-DQ and IFNL4 were associated with HBV infection and clearance in a Chinese population. Methods: The Sequenom MassARRAY MALDI-TOF system was used to genotype the HLA-DQrs9275319 and IFNL4rs368234815, rs12971396, rs12979860, and rs8099917. A binary logistic regression test was conducted to estimate the relative risk of these SNPs with HBV infection and clearance. Haploview4.2 software and PHASE software (v2.0.2) were employed to analyze linkage disequilibrium (LD) and haplotype frequencies. The MDR program was applied to analyze interactions between SNP and SNP.Statistical analysis was performed using SPSS 19.0 and P-values were corrected by Bonferroni’s corrections. Results: A total of 1,069 subjects were recruited and divided into three groups: 238 healthy controls(HC), 397 with HBV-related chronic liver disease (CLD), 434 with spontaneous clearance (SC). The rs9275319TT was most frequently identified among all groups(86.2% in the CLD group, 77.6% in the SC group, and 75.9% in the HC group).Carriage of the rs9275319 C allele was a protective factor for chronic HBV infection (the allele model: P = 0.000 3, OR,0.514; 95% CI, 0.359-0.738) and clearance (the allele model: P = 0.002, OR, 1.659; 95% CI, 1.197-2.300). HLA-DQ rs9275319 showed a significant association with HBV infection (allele model, OR, 0.514; 95% CI, 0.359-0.738, adjusted P = 0.000 3) and spontaneous clearance (allele model, OR, 1.659; 95% CI, 1.197-2.300, adjusted P = 0.002). However, there was no association between IFNL4 polymorphism and HBV infection((allele model: P = 0.082 for rs368234815; P = 0.063 for rs12971396; P = 0.517 for rs12979860; P =0.695 for rs8099917) or spontaneous clearance ((allele model: P = 0.358 for rs368234815; P = 0.105 for rs12971396; P = 0.640 for rs12979860; P = 0.640 for rs8099917;all P > 0.05). The multifactor dimensionality reduction (MDR) test showed there was a three-way interaction (rs12971396, rs12979860, and rs9275319) between IFNL4 and HLA-DQ polymorphisms for HBV infection (permutation P = 0.009 for the best factor model) and clearance (permutation P = 0.014 for the best factor model). Conclusion The SNP-SNP interaction between HLA-DQ and IFNL4 is associated with the regulation of HBV infection and natural clearance.
