BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

OBJECTIVE: To investigate the efficacy and safety of combination regimen containing daratumumab in multiple myeloma (MM) patients. METHODS: The clinical data of 14 newly diagnosed MM patients and 58 relapsed refractory MM patients treated with combination regimen containing daratumumab from November 2020 to March 2023 in the First Affiliated Hospital of Nanchang University were retrospectively analyzed. The efficacy and safety of combination regimen were analyzed. RESULTS: The median age of the 72 patients was 62 (38-78) years, including 35 males and 37 females. The overall response rate (ORR) of patients receiving first-line, second-line, and third-line or above treatment was 92.9% (13/14), 68.2% (30/44), and 42.9% (6/14), respectively. The median progression-free survival (PFS) was not reached, 15.4 months, and 9.7 months in three groups, respectively (all P <0.05), while the median overall survival (OS) was all not reached. Among relapsed refractory patients, the ORR of those treated with DVd, DPd and DRd regimen was 50.0% (12/24), 40.0% (4/10) and 100% (10/10), the median PFS was 2.8 months, 10.3 months and not reached, and the median OS was 15.4 months, not reached and not reached, respectively. Furthermore, the PFS and OS in the DRd group were superior to those in the other two groups (all P <0.05). Cox univariate and multivariate analysis showed that lactate dehydrogenase (LDH) ≥250 U/L and extramedullary disease were independent adverse prognostic factors for PFS, and LDH ≥250 U/L was also an independent adverse prognostic factor for OS. Hematologic adverse reactions were mainly lymphopenia (87.5%) and thrombocytopenia (52.8%), while non-hematologic adverse reactions were mainly infusion-related reactions (19.4%) and infections (11.1%). CONCLUSIONS The combination regimens containing daratumumab can be used as first-line treatment for patients with newly diagnosed MM. In patients with relapsed refractory MM, early use of regimens containing daratumumab may improve treatment response rate and prolong PFS. The DRd regimen has better therapeutic response and survival advantages. LDH is an independent prognostic factor affecting PFS and OS in MM patients.

OBJECTIVE: Asthma imposes a significant global health burden. This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios. METHODS: Using data from the Global Burden of Disease 2021 study, we analyzed asthma incidence, prevalence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2021. We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled. Temporal trends in age-standardized incidence, prevalence, mortality, and DALY rates were explored using Annual Percent Change. RESULTS: In 2021, the age-standardized rates for asthma incidence, prevalence, mortality, and DALYs in China were 364.17 per 100,000 (95% uncertainty interval [ UI]: 283.22-494.10), 1,956.49 per 100,000 (95% UI: 1,566.68-2,491.87), 1.47 per 100,000 (95% UI: 1.15-1.79), and 103.76 per 100,000 (95% UI: 72.50-145.46), respectively. A higher disease burden was observed among Chinese men and individuals aged 70 years or older. Compared to the current trend, a combined scenario involving improvements in environmental factors, behavioral and metabolic health, child nutrition, and vaccination resulted in a greater reduction in the disease burden caused by asthma. CONCLUSION Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.

OBJECTIVE: To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study. METHODS: This prospective, community-based cohort study included 12,054 patients with diabetes. From 2006 to 2012, 38,272 fasting blood glucose (FBG) measurements were obtained from these participants. FBG trajectory patterns were generated using latent mixture modelling. Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns. RESULTS: At baseline, the mean age of the participants was 55.2 years. Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period. After a median follow-up of 6.9 years, 786 cerebral infarction events were recorded. Different trajectory patterns were associated with significantly varied outcome risks (Log-Rank P < 0.001). Compared with the low-stability group, Hazard Ratio ( HR) adjusted for potential confounders were 1.37 for the moderate-increasing group, 1.23 for the elevated-decreasing group, and 2.08 for the elevated-stable group. CONCLUSION Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes. Controlling FBG levels may reduce the risk of cerebral infarction.

Chrysophanol(Chr)and physcion(Phy)are primary active ingredients of a well-known traditional Chinese medicine namely rhubarb(Chinese name:Dahuang),and their glucuronides have been revealed as the dominant forms presenting in rats after oral administration.Either Chr or Phy has two glycosylation sites,resulting in a pair of positional isomers for glucuronides of either compound(CG1&CG2 and PG1&PG2).To confirmatively identify these glucuronides,energy-resolved mass spectrometry(ER-MS)was used to pursue the fragmentation trajectories of the targeted fragment ions,and the resultant breakdown graphs that were described by the optimal collision energy(OCE)were expected to exhibit the differences of glycosidic bond cleavage between the isomers.Quantum chemical calculation was thereafter conducted to produce the bond dissociation energy(BDE)of the glycosidic bonds.The isomers were unambiguously identified through applying the positive correlation rule between OCE and BDE.Fortunately,the glucuronides of Chr and Phy in vivo were observed through liver microsomes incubationin vitro.ER-MS was utilized to collect the Gaussian-shaped breakdown graphs in response to the neutral loss of 176 Da,and the absolute values of OCE were compared between positional isomers.The results revealed that CG1(-32.31 eV)>CG2(-31.61 eV),and nonetheless,PG1(-30.00 eV)Chr-8-GluA(-48.787 kJ/mol),and nonetheless,Phy-1-GluA(-48.672 kJ/mol)

Objective:To analyze the genetic characteristics of varicella-zoster virus（VZV）in Anhui province from 2022 to 2023.Methods:Vesicle fluid and throat swab samples were collected from suspected varicella patients in Anhui province during 2022—2023. Fresh vesicle fluid samples were selected for VZV isolation，and real-time PCR was used for VZV nucleic acid detection. For positive samples，the region containing five single nucleotide polymorphism（SNP）sites in the open reading frame 22（ORF22）fragment was amplified，and PCR products were sequenced to identify viral genotypes. Reference sequences of VZV genotypes were downloaded from GenBank，sequence alignment and phylogenetic tree analysis were performed using Sequencher and MEGA5.0 software. Additionally，four SNP sites in ORF38 and ORF62 fragments were detected to distinguish vaccine strains from wild strains.Results:Among 96 samples from suspected varicella cases，55 of 61 vesicle fluid samples and 21 of 35 throat swab samples were positive for VZV nucleic acid. The virus isolation rate for vesicle fluid samples was 14.75%. Genetic sequencing was successful for 51 strains，all of which were wild strains belonging to the clade 2 genetic branch. Compared with the reference strain of clade 2，the nucleotide and amino acid homologies of the ORF22 fragment were 99.46%~100% and 98.39%~100%，respectively. One strain（2023VZVCZ45）exhibited an A→G mutation at site 37916.Conclusion:The prevalent VZV strains detected in Anhui province during 2022—2023 were all wild strains of clade 2，with no vaccine-associated cases identified.

Objective:To investigate the radioactivity levels and variation trends of 90Sr in drinking water and food around the Qinshan Nuclear Power Plant in operation. Methods:From 2012 to 2022, the source, factory, and tap water was collected within 30 km around the Qinshan Nuclear Power Plant during the wet and dry seasons (i.e., May and October, respectively) each year to determine the 90Sr concentration in water. According to the dietary habits of local residents, four kinds of food, including rice, cabbage, mullet, and crucian carp, were collected to determine and analyze the 90Sr radioactivity concentration in food using the bis-(2-ethylhexyl) phosphoric acid extraction chromatographic method. Results:From 2012 to 2022, the 90Sr radioactivity concentrations in the source, factory, and tap water around the Qinshan Nuclear Power Plant ranged from 3.73 to 11.89 mBq/L, 2.95 to 9.83 mBq/L, and 3.12 to 8.70 mBq/L, respectively, showing nonsignificant fluctuations over the years. The 90Sr radioactivity concentrations in rice, cabbage, mullet, and crucian carp ranged from 0.02 to 0.46 Bq/kg (dry weight), 0.26 to 1.07 Bq/kg (fresh weight), 0.38 to 1.05 Bq/kg (fresh weight), and 0.08 to 1.32 Bq/kg (fresh weight), respectively, all below the national standard limits. Conclusions:From 2012 to 2022, the 90Sr radioactivity levels in drinking water and food around the Qinshan Nuclear Power Plant were at the background level and remained stable.

Objective:To analyze the evolution of ceftazidime/avibactam (CZA) resistance phenotyes and clinical features of 11 ST11-KL64 carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates carrying bla KPC. Methods:Eleven CRKP isolates, designated K01 to K11, obtained from infected liver transplant patients from June to September 2024 were retrospectively studied. Broth microdilution method, whole genome sequencing (WGS) and plasmid conjugation assays were employed to investigate the antimicrobial susceptibility, resistance mechanisms, and genetic structural characteristics of these CRKP isolates. Clinical data were simultaneously collected and organized to analyze the correlation between bla KPC gene mutations and the clinical efficacy of antimicrobial therapy. Results:All eleven isolates of CRKP exhibited multidrug resistance phenotypes. Among them, K01-K09 and K11 were sensitive to CZA and resistant to carbapenems, while K10 was resistant to CZA and displayed sensitivity or intermediate resistance to carbapenems. WGS analysis showed that all 11 CRKP isolates belonged to the ST11-KL64 clonal type. Among these isolates, the K01-K09 and K11 isolates carry the bla KPC-2 gene, whereas the K10 isolate carries the bla KPC-33 gene. A single nucleotide mutation in bla KPC-2 (G532T) resulted in a substitution of tyrosine (Y) for aspartic acid (D) at Ambler position 179 (D179Y), causing resistance of CRKP to CZA and reduced sensitivity to Imipenem and Meropenem. The conjugative plasmid was successfully constructed, and compared to the parental strain, its minimum inhibitory concentration (MIC) to CZA increased 32 folds. Clinical data revealed that the patient developed the bla KPC-33 mutation after 51 days of CZA treatment. Conclusions:The bla KPC-33 mutation following CZA treatment for CRKP infection exhibits a considerable delay. It is essential to dynamically monitor the evolution of CRKP resistance to ensure timely adjustment of therapeutic strategies in case of the occurrence of mutations such as bla KPC-33.

OBJECTIVE: To explore the clinical features and genetic characteristics of three patients with Infantile liver failure syndrome type 2 (ILFS2). METHODS: Three children who were diagnosed with ILFS2 at the Children's Hospital Affiliated to Zhengzhou University from February 2023 to February 2024 were selected as the study subjects. Clinical data of the children were collected. Peripheral blood samples of the children and their parents were collected and subjected to whole exome sequencing (WES). Candidate variants of the NBAS gene were verified by Sanger sequencing. This study was approved by the Ethics Committee of the Children's Hospital Affiliated to Zhengzhou University (Ethics No. 2024-k-069). RESULTS: The three children had presented with fever-triggered recurrent acute liver failure. All of them were found to harbor compound heterozygous variants of the NBAS gene, including c.3596G>A and c.1181A>T in child 1, c.2617C>T and c.2T>C in child 2, and c.3596G>A and c.2817_2818insT in child 3. Among these, the c.1181A>T and c.2817_2818insT variants were unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), they were respectively classified as variants of uncertain significance (PM2_Supporting+PM3+PP3) and pathogenic (PVS1+PM2_Supporting+PM3). CONCLUSION Combined with the patient's clinical phenotype, the compound heterozygous variants of the NBAS gene probably underlay the pathogenesis of ILFS2 in the three children. For children with fever-related acute liver failure of unknown causes, the possibility of this disease should be suspected, and genetic testing may facilitate the diagnosis. Early diagnosis and timely intervention can significantly improve the prognosis. Discoveries of the c.1181A>T and c.2817_2818insT variants have enriched the mutational spectrum of the NBAS gene.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.
