OBJECTIVE To systematically evaluate the correlation between dynamic changes in inflammatory markers during treatment with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） in non-small cell lung cancer （NSCLC） patients and therapeutic efficacy， with the aim of providing evidence-based support for clinical prognosis assessment and treatment strategy adjustment. METHODS Databases including PubMed， Embase， Cochrane Library， CNKI， Wanfang Data， and CBM were searched from the inception to July 20， 2025. Following literature screening， data extraction and quality assessment， descriptive analysis was conducted on the outcomes of included studies. RESULTS A total of eight studies were included to analyze the correlation of 6 inflammatory markers before and after treatment with EGFR-TKIs with therapeutic efficacy. The risk of bias assessment identified six high-quality studies and two moderate-quality studies. Among these studies， seven studies demonstrated that lower levels of neutrophil-to-lymphocyte ratio （NLR）， derived neutrophil-to-lymphocyte ratio （dNLR）， platelet-to-lymphocyte ratio （PLR）， and monocyte-to-lymphocyte ratio （MLR）， higher lymphocyte-to-monocyte ratio （LMR） before treatment， as well as decreased NLR and MLR and increased LMR after treatment were associated with longer median progression-free survival. Five studies indicated that lower levels of NLR， dNLR， PLR， and interleukin-6 （IL-6）， higher LMR before treatment as well as decreased NLR and dNLR and increased LMR were associated with longer median overall survival. Three studies indicated that lower levels of IL-6 were associated with a higher objective response rate， while the association of these markers after treatment remained controversial； another study showed that an early decline in NLR， MLR， and PLR after treatment may be associated with objective response benefit. CONCLUSIONS Lower inflammatory levels during EGFR-TKIs therapy correlate with better therapeutic efficacy in NSCLC patients.

Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

Puerariae Lobatae Radix and Puerariae Thomsonii Radix are the dried roots of Pueraria lobata and Pueraria thomsonii of the Leguminosae family， respectively. Since their separate inclusion in the 2005 edition of Pharmacopoeia of the People's Republic of China， the two herbs have been individually recorded. Although they share the same functions and indications， the required content of puerarin differs by a factor of up to eightfold between them. The current quality standard relies solely on a single indicator， puerarin， which fails to reflect the correlation between chemical constituents and core therapeutic effects. This has resulted in prominent issues of mixed use in clinical practice and production， thereby constraining the high-quality development of the industry. Modern research has demonstrated that Puerariae Lobatae Radix contains a comprehensive range and higher content of isoflavonoid constituents， while Puerariae Thomsonii Radix is rich in starch and polysaccharides. Puerariae Lobatae Radix exhibits stronger effects in antipyresis， cardiovascular and cerebrovascular protection， and central analgesia， while Puerariae Thomsonii Radix demonstrates greater advantages in anti-inflammation， hypoglycemia， and peripheral analgesia. Based on this， the chemical material bases of Puerariae Lobatae Radix and Puerariae Thomsonii Radix at both the macromolecule and micromolecule levels were systematically reviewed and compared. The pharmacodynamic material bases and mechanisms of action underlying their three core therapeutic effects， namely "relieving exterior syndrome and clearing heat"， "promoting fluid production to quench thirst"， and "dredging channels and activating collaterals"， were summarized. The most highly correlated common metabolic pathway shared by both herbs for these three therapeutic effects is the arachidonic acid metabolic pathway， and their common core target is prostaglandin-endoperoxide synthase 2 （PTGS2）. This review provided clinical application recommendations based on the therapeutic differences between the two herbs， elucidated the scientific connotation of their "same origin but different effects"， and， grounded in the quality marker （Q-Marker）， proposed the concept of efficacy-related Q-Marker based on "substance-efficacy-syndrome" association， as well as a novel strategy for efficacy-oriented quality evaluation. Preliminary screening of quality markers associated with different therapeutic effects was also conducted. This study aims to provide critical scientific evidence for the precise clinical application of Puerariae Lobatae Radix and Puerariae Thomsonii Radix， the improvement of quality standards， and the high-quality development of the industry.

Objective To analyze the emergency testing results of a mixed poisoning incident involving methyl acetate and dimethyl carbonate in a composite fabric processing enterprise. Methods A mixed poisoning incident involving methyl acetate and dimethyl carbonate occurred at a composite fabric processing enterprise in a city of Guangdong Province. On-site occupational health investigation data and laboratory testing results related to this incident were collected, and an integrated analysis was conducted. Results The on-site occupational health investigation revealed inadequate ventilation and non-standard use of personal protective equipment. Volatile organic component analysis of raw and auxiliary materials showed that methyl acetate and dimethyl carbonate had relatively high percentages of peak area among all used volatile organic chemical agents in post-incident emergency testing, accounting for 65.10% and 38.25%, respectively. The exposure concentration of short term (C_STE) of methyl acetate in the production line air was 15.13 mg/m³. In the chemical storage area, C_STE of methyl acetate and methanol were 451.04 and <0.21 mg/m³, respectively, all below their respective occupational exposure limits (500.00 and 50.00 mg/m³). In the poisoned workers, blood methanol, blood formic acid, and urinary formic acid levels were 147, 414, and 4 389 mg/L, respectively. Conclusion Occupational exposure to methyl acetate and dimethyl carbonate may lead to acute occupational poisoning and cause health damage. Employers should fulfill their responsibilities for occupational disease prevention by ensuring proper operation of protective facilities, while workers should enhance awareness of occupational disease prevention and correctly use personal protective equipment.

Objective To establish a method for simultaneous determination of four high-molecular-weight thiol derivatives (TDs) in workplace air by gas chromatography. Methods The four kinds of vapor-phase macromolecular TDs (1-pentanethiol, 1-hexanethiol, 1-benzyl mercaptan, and n-octanethiol) in the workplace air were collected using the GDH-1 air sampling tubes, desorbed with anhydrous ethanol, separated on a DB-FFAP capillary column, and determined by flame ionization detector. Results The quantitation range of the four TDs was 0.30-207.37 mg/L, with the correlation coefficients greater than 0.999 00. The minimum detection mass concentrations and minimum quantitation mass concentrations were 0.18-0.32 and 0.60-1.05 mg/m³, respectively (both calculated based on the 1.5 L sample and 3.0 mL desorption solvent). The mean desorption efficiencies ranged from 87.07% to 103.59%. The within-run and between-run relative standard deviations were 1.92%-8.22% and 1.89%-8.45%, respectively. The samples can be stored at room temperature or 4 ℃ for three days and up to 7 days at -18 ℃. Conclusion This method is suitable for the simultaneous determination of four vapor-phase TDs in workplace air.

Triple-negative breast cancer (TNBC) is aggressive, with high recurrence rates and poor prognosis. Paclitaxel (PTX) remains a key chemotherapeutic agent for TNBC, but its efficacy diminishes due to the emergence of drug resistance, largely driven by cancer stem-like cells (CSCs), vasculogenic mimicry (VM) formation and tumor immunosuppressive microenvironment (TIME). Pyruvate kinase M2 (PKM2) is highly expressed in TNBC, and is a potential target for TNBC treatment. In this study, we developed a biomimetic codelivery system using albumin nanoparticles (termed S/P NP) to co-encapsulate PTX and shikonin (SHK), a natural inhibitor of PKM2. By inhibiting PKM2, SHK suppressed β-Catenin signaling, thereby reversing CSC stemness and preventing VM formation. The S/P NP system exhibited tumor-targeting delivery effect and significantly inhibited TNBC growth and lung metastasis. Mechanistically, the treatment reversed epithelial-mesenchymal transition (EMT) and stem-like properties of TNBC cells, suppressed VM formation, and remodeled the TIME. It reduced immunosuppressive cells (M2 macrophages, MDSCs) while promoting anti-tumor immunity (M1 macrophages, dendritic cells, cytotoxic T cells, and memory T cells). This dual-action strategy holds promise for improving TNBC therapy by targeting CSCs, VM, and the immune microenvironment, and for overcoming PTX resistance and reducing metastasis.

Objective To explore the short-term efficacy of endoscopic submucosal dissection (ESD) in the treatment of early carcinoma in the remnant stomach. Methods A retrospective study was conducted on 45 patients with early residual gastric cancer underwent ESD at the Endoscopy Center of Zhongshan Hospital, Fudan University from December 2014 to April 2024, with a total of 45 lesions. The patients were divided into an anastomotic group (n=15) and a non-anastomotic group (n=30) based on the location of tumor occurrence, and their clinical data, endoscopic diagnosis and treatment, and histopathological conditions were compared between the two groups. Results All 45 patients had lesions with redness and erosion. There were 9 cases of poor lifting of submucosal injection in the anastomotic group and 2 cases in the non-anastomotic group, respectively, and the difference was statistically significant (P<0.05). ESD surgery was performed on 13 lesions in the anastomotic group and 28 lesions in the non-anastomotic group, with surgery times of 80.00 (50.00, 100.00) min and 55.00 (43.75, 80.00) min, respectively. The difference in surgery time between the two groups was statistically significant (P=0.03). Among the 45 patients, ESD surgery achieved curative resection in 35 cases, including 11 cases in the anastomotic group and 24 cases in the non-anastomotic group, with no statistically significant difference. Conclusions Careful preoperative evaluation of early carcinoma in the remnant stomach is essential to prevent oversight. Lesions at anastomotic sites and suture lines present higher technical challenges for complete resection. ESD is safe and effective, with auxiliary traction technique available when necessary.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

Objective:To investigate the impact of high-density lipoprotein (HDL) subfraction cholesterol, measured by the vertical auto profile (VAP) technique based on vertical density gradient ultracentrifugation, on the occurrence and progression of coronary heart disease.Methods:This retrospective case-control study consecutively enrolled 94 inpatients diagnosed with coronary artery disease (CAD) by percutaneous coronary angiography at Ningbo University Affiliated First Hospital between June 2023 and June 2024 (CAD group), and 48 outpatients from the cardiology department without carotid or coronary atherosclerosis(non-CAD group). The VAP technique was employed to measure HDL subfraction cholesterol levels (HDL 3-C and HDL 2-C) and their subtypes (HDL 2a-C, HDL 2b-C, HDL 2c-C; HDL 3a-C, HDL 3b-C, HDL 3c-C, HDL 3d-C). Logistic regression analysis was performed to assess the association between HDL subfraction composition and CAD. CAD patients were further stratified by the number of affected coronary vessels (left anterior descending artery, left circumflex artery, and right coronary artery): 44 with single-vessel disease, 22 with double-vessel disease, and 28 with triple-vessel disease for correlation analysis. All CAD patients underwent 6-month clinical and telephone follow-up to record major adverse cardiovascular events (MACE), including acute myocardial infarction, stroke, and repeat revascularization. Using the median HDL 3d-C level (0.064 mmol/L) as cutoff, CAD patients were divided into high-level ( n=48) and low-level ( n=46) subgroups for Kaplan-Meier survival analysis with log-rank testing. Results:Compared with non-CAD controls, CAD patients showed significantly higher HDL 3d-C [0.064 (0.041, 0.095) mmol/L vs 0.055 (0.038, 0.067) mmol/L] and HDL 3b-C [0.031 (0.001, 0.054) mmol/L vs 0.007 (0.004, 0.029) mmol/L], lower HDL 3c-C (0.220±0.080 mmol/L vs 0.254±0.062 mmol/L) and HDL 3a-C [0.282 (0.224, 0.351) mmol/L vs 0.334 (0.269, 0.433) mmol/L] (all P<0.05). Logistic regression revealed that HDL2b-C was a protective factor against atherosclerosis severity ( OR=0.914, 95% CI 0.896-0.987, P<0.001); HDL 3d-C served as both a CAD risk factor ( OR=2.303,95% CI 1.740-3.047, P<0.001) and disease progression indicator ( OR=1.224, 95% CI 1.123-1.335, P=0.025). MACE patients ( n=6) had elevated HDL3d-C versus non-MACE cases ( n=88) [0.120 (0.083, 0.173) mmol/L vs 0.061 (0.037, 0.092) mmol/L, P<0.05]. The high HDL 3d-C subgroup demonstrated significantly lower 6-month survival (χ2=4.777, P=0.029). Conclusion:Contrary to conventional understanding, our study reveals that HDL2b serves as a protective factor against coronary artery disease progression, whereas HDL 3d-C acts not only as a pathogenic factor for CAD but also as a critical determinant of CAD-related adverse events.

To explore the clinicopathological characteristics, endoscopic manifestations, and efficacy of endoscopic procedure for early gastroesophageal junction cancer, a retrospective analysis was conducted on the patients who underwent endoscopic submucosal dissection (ESD) and pathologically confirmed early cancer of the gastroesophageal junction at Zhongshan Hospital, Fudan University and Xiamen Branch from November 2014 to October 2021. The pathological and gastroscopic features, as well as short-term efficacy of ESD were analyzed. Among the 401 patients, there were 332 males with the age of 66.02±7.93 years, and 69 females with the age of 66.26±9.31 years. The male-to-female ratio was 4.8∶1. Siewert type Ⅱ accounted for 70.82% (284/401). Lesions involving the lesser curvature accounted for 57.10% (229/401). Endoscopic manifestation of mucosal erythema accounted for 96.26% (386/401). Lesion morphology of 0-Ⅱc type accounted for 38.15% (153/401) and tubular adenocarcinoma accounted for 86.53% (347/401). The en bloc resection rate of ESD was 99.75% (400/401), with a curative resection rate of 72.82% (292/401). It is indicates that early gastroesophageal junction cancer predominantly occurs in middle-aged and elderly males. It is mostly Siewert type Ⅱ, and involves the lesser curvature, and primarily presents as type 0-Ⅱc morphology. The lesions are most commonly manifested as mucosal redness and are predominantly moderately to well-differentiated adenocarcinomas. ESD demonstrates a safe and effective therapeutic approach for early gastroesophageal junction cancer.
