The focus of green analytical chemistry (GAC) is to minimize the negative impacts of analytical procedures on human safety, human health, and the environment. Several factors, such as the reagents used, sample collection, sample processing, instruments, energy consumed, and the quantities of hazardous materials and waste generated during analytical procedures, need to be considered in the evaluation of the greenness of analytical assays. In this study, we propose a greenness evaluation metric for analytical methods (GEMAM). The new greenness metric is simple, flexible, and comprehensive. The evaluation criteria are based on both the 12 principles of GAC (SIGNIFICANCE) and the 10 factors of sample preparation, and the results are presented on a 0-10 scale. The GEMAM calculation process is easy to perform, and its results are easy to interpret. The output of GEMAM is a pictogram that can provide both qualitative and quantitative information based on color and number.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, which can lead to damage to a variety of organs, including the heart, lungs, kidneys, liver, and brain. Pyroptosis is a form of inflammatory cell death, marked by the sequential events of membrane pore formation, cellular swelling leading to rupture, and subsequent release of pro-inflammatory cytokines. In recent years, numerous studies have demonstrated a close association between pyroptosis and sepsis. Pyroptosis extensively contributes to the onset and progression of sepsis through various pathways while also being regulated by multiple factors. This article reviews the role and mechanisms of pyroptosis in sepsis-induced organ injury.

Objective:To explore the anal function and postoperative complications of 2-stage Turnbull-Cutait pull-through coloanal anastomosis (TCA) for low rectal cancer.Methods:Patients undergoing radical rectal cancer resection from Feb 2023 to Nov 2024 in the First Hospital of Jilin University were divided into the TCA surgery group and the low anterior resection combined with prophylactic stoma (LAR) surgery group.Results:Among the 102 patients, there were 50 cases in the TCA group and 52 cases in the LAR group. In the single-arm analysis of the TCA group, the overall complication rate was 44%. The incidence rates of severe LARS at 1 month, 3 months, and 6 months after surgery were 97%, 77%, and 64% respectively. There was no significant difference in the complication rate within 30 days after surgery between the two groups,(44% vs. 38%, χ2=0.135, P>0.05). There was no significant difference in the incidence rate of severe LARS between the TCA group and the LAR group (77% vs. 69%, χ2=0.202, P>0.05), and there was not significant difference in the incidence rate of severe LARS between the two groups at the 6th month after surgery,(64% vs. 48%, χ2=1.132, P>0.05). Conclusion:In patients who underwent TCA surgery, the LARS symptoms gradually decreased over time. Compared with patients undergoing low anterior resection and stoma reversal, there were no significant differences in complications within 30 days after surgery and LARS symptoms within half a year.

Objective:To investigate the predictive value of neutrophil extracellular traps (NETs) on the prognosis of patients with epidermal growth factor receptor (EGFR) wild-type lung adenocarcinoma.Methods:A total of 132 surgical paraffin specimens of EGFR wild-type lung adenocarcinoma diagnosed at the Tumor Hospital Affiliated to Xinjiang Medical University from January 2016 to December 2023 and 12 pairs of cancer and paracancerous fresh tissues from patients with EGFR wild-type lung adenocarcinoma diagnosed in March-July 2024 were collected with their clinical information. Western blotting and immunofluorescence were used to detect the expression levels of citrullinated histone H3 (CitH3) and myeloperoxidase (MPO) in cancerous and paraneoplastic tissues. Immunohistochemistry was used to detect the infiltration of PD-L1, CD4 + T cells and CD8 + T cells in the tumors. The clinical and prognostic correlations between NETs and EGFR wild-type lung adenocarcinoma patients were analyzed. Results:The expression of MPO ( P＜0.001) and CitH3 ( P=0.009) was significantly increased in the tumors compared with the paracancerous tissues. The rate of high expression of NETs in cancer tissues was higher in patients with EGFR wild-type lung adenocarcinoma who were in stage Ⅲ and Ⅳ, with lymph node metastasis, distant metastasis, pleural invasion, high expression of Ki-67, low expression of CD8 + T, and lowered lymphocyte counts when compared to paraneoplastic tissues ( P＜0.05). Patients were stratified based on TNM stage Ⅱb for prognostic analysis. Kaplan-Meier univariate analysis showed that the median overall survival (OS) (stage Ⅰ to Ⅱb: 47 vs 87 months; stage Ⅲ to Ⅳ: 27 months vs not reach) and the median disease-free survival (DFS) (stage Ⅰ to Ⅱb: 42 vs 78 months; stage Ⅲ to Ⅳ: 18 vs 39 months) of patients with high expression of NETs in stage Ⅰ to II b and stage Ⅲ to Ⅳ were lower than those with low expression (stage Ⅰ to Ⅱb: OS, P＜0.001; DFS, P＜0.001; stage Ⅲ to Ⅳ: OS, P=0.001; DFS, P=0.022). The OS (stage Ⅰ to Ⅱb: HR=3.513, 95% CI: 1.966-6.277, P＜0.001; stage Ⅲ to Ⅳ: HR=3.215, 95% CI: 1.324-7.806, P=0.010) and the DFS (stage Ⅰ to Ⅱb: HR=2.478 ,95% CI: 1.396-4.400, P=0.002; stage Ⅲ to Ⅳ: HR=2.248, 95% CI: 1.089-4.638, P=0.028) in the group with high expression of NETs in either stage Ⅰ to Ⅱb or stage Ⅲ to Ⅳ were significantly shorter than those in the group with low expression. Conclusion:The EGFR wild-type lung adenocarcinoma patients with high expression of NETs have relatively shorter DFS and OS, which are independent risk factors for the prognosis of patients with EGFR wild-type lung adenocarcinoma, and are likely to be the potential biomarkers for the diagnosis and treatment of EGFR wild-type lung adenocarcinoma.

Objective:To explore the clinical features and prognostic factors of lymphoma-associated hemophagocytic lymphohistiocytosis (LAHS).Methods:A retrospective cohort study was conducted. The clinical data of 44 LAHS patients who diagnosed at the Second Hospital of Shanxi Medical University from September 2016 to September 2022 were retrospectively analyzed. All patients were divided into B cell LAHS (B-LAHS) group (19 cases) and NK/T cell LAHS (NK/T-LAHS) group (19 cases) according to the lymphoma types, except for 4 cases of classic Hodgkin lymphomas and 2 cases of splenic lymphoma lymphomas. The clinical features and the factors influencing the prognosis of both groups were compared. According to whether lymphoma treatment were included in the initial treatment regimen, the patients were divided into the group with lymphoma treatment and the group without lymphoma treatment, and the objective response rate (ORR) of both groups was compared. Kaplan-Meier method was used to analyze the overall survival (OS), the log-rank method was used for univariate analysis, and the Cox proportional hazards model was used for multivariate analysis.Results:Among 44 LAHS patients, 26 cases were male and 18 cases were female, with the age of (69±7) years. Most of them were secondary to diffuse large B-cell lymphoma (DLBCL), and 17 out of 44 patients were secondary to DLBCL. All patients had fever, lymphadenopathy, and ferritinemia. The differences in red blood cells (RBC), hemoglobin (Hb), activated partial thromboplastin time (APTT), peripheral blood Epstein-Barr virus DNA (EBV DNA) load, positive rate of Epstein-Barr virus-encoded small RNA (EBER) in tissues, triglycerides (TG), aspartate aminotransferase (AST) and fibrinogen between NK/T-LAHS patients and B-LAHS patients were statistically significant (all P<0.05). The ORR of 44 patients with LAHS was 52.3% (23/44); the median OS time of LAHS patients was 157 d, and that of NK/T-LAHS patients was 110 d; the median OS time of B-LAHS was 135 d; and the difference was statistically significant ( χ2 = 7.47, P = 0.024). The median OS was not reached in patients receiving initial treatment regimen containing lymphoma, while the median OS time was 65 d in patients receiving treatment without containing lymphoma, and the difference was statistically significant ( χ2 = 3.97, P = 0.046). The results of multivariate Cox proportional hazards model showed that age ≥ 70 years ( HR = 2.502, 95% CI: 1.047-5.978, P = 0.039), serum ferritin (SF) ≥ 1 500 μg/L( HR=0.521,95% CI:0.282~0.960, P=0.037), soluble CD25 ≥ 7 800 U/ml ( HR = 0.536, 95% CI: 0.348-0.828, P = 0.005), interleukin (IL)-10≥100 ng/L ( HR = 0.532, 95% CI: 0.33-0.85, P = 0.009), interferon (IFN)-γ≥5.0 ng/ L ( HR = 0.554, 95% CI: 0.32-0.95, P = 0.033), Th (CD3 + CD4 + T cells)/ Ts (CD3 + CD8 + T cells) < 2 ( HR = 1.731, 95% CI: 1.005-2.982, P = 0.048), and hepatomegaly ( HR = 2.581, 95% CI: 1.059-6.289, P = 0.037) were independent factors influencing the poor outcome of LAHS patients. Conclusions:LAHS is mostly secondary to DLBCL. The early clinical manifestations lack specificity and the prognosis is generally poor, and the worst prognosis occurs in patient with NK/T-LAHS. The initial treatment with lymphoma can prolong OS time in patients with LAHS.
