Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

ObjectiveTo observe the clinical effect of modified Huanglian Wendantang on cardiovascular risk factors in patients with metabolic syndrome under the guidance of treating disease before its onset. MethodsA total of 82 patients with metabolic syndrome treated in the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from July 2023 to July 2024 were selected and allocated into an observation group (41 cases) and a control group (41 cases) by the random number table method. The control group received routine treatment, and the observation group was treated with modified Huanglian Wendantang on the basis of routine treatment. Both groups were treated for 8 weeks. The therapeutic effects on TCM symptoms after treatment in the two groups were evaluated. The levels of obesity degree indicators, blood pressure indicators, glucose and lipid metabolism indicators, inflammatory factors, and vascular endothelial function indicators before and after treatment in the two groups were measured, and the treatment safety was evaluated. ResultsAfter treatment, the total response rate of TCM symptoms in the observation group was 97.56% (40/41), which was higher than that (87.80%, 36/41) in the control group (χ2=5.205, P<0.05). After treatment, both groups showed declines (P<0.05) in systolic blood pressure (SBD), diastolic blood pressure (DBP), triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), fasting blood glucose, 2-hour postprandial blood glucose (2 h PG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), leptin (LEP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), endothelin-1 (ET-1), and inducible nitric oxide synthase (iNOS). Moreover, the declines in the observation group were more obvious than those in the control group (P<0.05, P<0.01). After treatment, both groups showed elevated levels of high density lipoprotein cholesterol (HDL-C), adiponectin (ADP), nitric oxide (NO), and endothelial nitric oxide synthase (eNOS) (P<0.05), and the above indexes in the observation group were higher than those in the control group (P<0.01). ConclusionUnder the guidance of the thought of treating disease before its onset, modified Huanglian Wendantang was used to treat patients with metabolic syndrome. The decoction improved the clinical efficacy by ameliorating IR to improve insulin sensitivity, reducing inflammation, and protecting the vascular endothelial function. It inhibits cardiovascular risk factors without inducing adverse reactions, being worthy of clinical application and promotion.

ObjectiveTo investigate the effects of different concentrations of Shaoyaotang-containing serum on lipopolysaccharide (LPS)-induced inflammation of human colorectal adenocarcinoma (Caco-2) cells by inhibiting apoptosis via activating the tumor necrosis factor (TNF) receptor superfamily member 6 (Fas)/Fas ligand (FasL) pathway. MethodsCaco-2 cells were allocated into blank, model (LPS, 10 mg·L-1), Shaoyaotang-containing serum (5%, 10%, 15%, 20%), and Fas inhibitor (KR-33493, 20 mmol·L-1) groups. Except the blank group, the other groups were stimulated with 10 mg·L-1 LPS for 24 h for the modeling of inflammation. After successful modeling, the blank, Fas inhibitor, and model groups were treated with blank serum, and the Shaoyaotang-containing serum groups were treated with the serum samples at corresponding concentrations for 24 h. The Fas inhibitor group was subjected to KR-33493 pretreatment for 1 h. Cell proliferation and viability were examined by the cell-counting kit-8 (CCK-8) method. The levels of interleukin (IL)-6, IL-1β, and TNF-α were measured by enzyme-linked immunosorbent assay. Apoptosis was detected by flow cytometry. The protein and mRNA levels of Fas, FasL, cysteinyl aspartate-specific proteinase (Caspase)-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) were determined by Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), respectively. ResultsCompared with the blank group, the model group presented a decrease in cell survival rate (P<0.01). Compared with that in the model group, the cell survival rate showed no significant change in the 5% Shaoyaotang-containing serum group but increased in the 10%, 15%, and 20% Shaoyaotang-containing serum groups (P<0.01). Since there was no statistical difference between the 5% Shaoyaotang-containing serum group and the model group, 10%, 15%, and 20% Shaoyaotang-containing sera were selected for the follow-up study. Compared with the blank group, the model group showed risen levels of IL-6, IL-1β, and TNF-α (P<0.01), an increased apoptosis rate (P<0.01), up-regulated protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.01), and down-regulated protein and mRNA levels of Bcl-2 (P<0.01). Compared with the model group, the Fas inhibitor group and the 10%, 15%, and 20% Shaoyaotang-containing serum groups showed declined levels of IL-6, IL-1β, and TNF-α (P<0.01), decreased apoptosis rates (P<0.01), down-regulated protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.05, P<0.01), and up-regulated protein and mRNA levels of Bcl-2 (P<0.05, P<0.01). In addition, the 15% and 20% Shaoyaotang-containing serum groups had lower levels of IL-6, IL-1β, and TNF-α (P<0.05, P<0.01), lower apoptosis rates (P<0.05, P<0.01), lower protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.05, P<0.01), and higher protein and mRNA levels of Bcl-2 (P<0.05, P<0.01) than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can reduce the content of inflammatory factors in Caco-2 cells, down-regulate the protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax, and up-regulate the protein and mRNA levels of Bcl-2 under the intervention of LPS by regulating the Fas/FasL pathway and inhibiting the apoptosis of intestinal epithelial cells in ulcerative colitis.

ObjectiveTo investigate the protective effect and mechanism of Shaoyaotang (SYD) on the lipopolysaccharide (LPS)-induced damage of tight junction proteins in the human colorectal adenocarcinoma (Caco-2) cell model of inflammation via the Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) pathway. MethodsCaco-2 cells were grouped as follows: Blank, model (LPS, 10 mg·L-1), SYD-containing serum (10%, 15%, and 20%), and inhibitor (Fasudil, 25 μmol·L-1). After 24 hours of intervention, the cell viability in each group was examined by the cell-counting kit 8 (CCK-8) method. Enzyme-linked immunosorbent assay was employed to determine the levels of endothelin-1 (ET-1), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of RhoA, ROCK2, claudin-5, and zonula occludens-1 (ZO-1) in cells of each group. ResultsCompared with the blank group, the model group showcased a marked reduction in the cell viability (P<0.01), elevations in the levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.01), declines in both mRNA and protein levels of ZO-1 and claudin-5 (P<0.01), and rises in mRNA and protein levels of RhoA and ROCK2 (P<0.01). Compared with the model group, the Shaoyaotang-containing serum (10%, 15%, and 20%) groups had enhanced cell viability (P<0.01), lowered levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.01), up-regulated mRNA and protein levels of ZO-1 and claudin-5 (P<0.05, P<0.01), and down-regulated mRNA and protein levels of RhoA and ROCK2 (P<0.01). Moreover, the inhibitor group and the 15% and 20% Shaoyaotang-containing serum groups had lower levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01), higher mRNA and protein levels of ZO-1 and claudin-5 (P<0.05, P<0.01), and lower mRNA and protein levels of RhoA and ROCK2 (P<0.05, P<0.01) than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can lower the levels of LPS-induced increases in levels of inflammatory cytokines and endothelin to ameliorate the damage of tight junction proteins of the Caco-2 cell model of inflammation by regulating the expression of proteins in the RhoA/ROCK pathway.

BACKGROUND:
Parental myopia is an important risk factor for myopia in Chinese children and adolescents. This study aimed to assess the influence of parental myopia and the severity of myopia on offspring and to evaluate whether adopting healthy lifestyles can mitigate the effects of parental myopia on offspring.
METHODS:
This cross-sectional study analyzed data from children and adolescents aged 6-17 years with complete vision assessments and parental history of myopia from six provinces in China during 2013-2014. Parental demographic information, children's outdoor activity time, sleep time, and sedentary time were collected via questionnaire. Parental myopia was classified as no myopia, paternal myopia, maternal myopia, and both. The offspring were categorized into 10 groups based on parental myopia prescription. Associations of the above factors with myopia in children and adolescents were evaluated by logistic regression analysis.
RESULTS:
Among 40,864 children and adolescents (50.3% boys and 49.7% girls), 22,537 (55.2%) were diagnosed with myopia. In comparison to offspring devoid of parental myopia, children with one parent affected by myopia exhibited odds ratio (OR) of 1.75 (95% confidence interval [CI]: 1.62-1.88) for myopia, while those with both parents affected showed OR of 2.27 (95% CI: 2.02-2.55) after adjusted for lifestyle factors. The likelihood of myopia in offspring increased with increasing severity of parental myopia, with a 3.08-fold increase in risk observed when both parents presented high myopia. Nonetheless, children adhering to two or more healthy lifestyle factors demonstrated a diminished risk of myopia compared with those with fewer than two lifestyle factors, especially among offspring of non-myopic or mildly myopic parents.
CONCLUSIONS
Parental myopia has a dose-dependent association with their offspring. Healthy lifestyles may reduce the impact of parental factors on myopia in offspring. The observed associations suggest that although the genetic burden of parental myopia cannot be ignored, healthy lifestyles and nurturing are also very important.

Based on copper death, this study investigates the effect and mechanism of Shenmai Injection on isoproterenol(ISO)-induced myocardial fibrosis(MF) in rats. SPF-grade male SD rats were randomly divided into a normal group, model group, captopril(5 mg·kg~(-1)) positive control group, and Shenmai Injection low(6 mL·kg~(-1)), medium(9 mL·kg~(-1)), and high(12 mL·kg~(-1)) dose groups. Except for the normal group, the rats in the other groups were subcutaneously injected with ISO(5 mg·kg~(-1)) once a day for 10 consecutive days to establish an MF model. Starting from the second day after successful modeling, intraperitoneal injections of the respective treatments were administered for 28 consecutive days. Hematoxylin-eosin(HE) and Masson staining were used to observe pathological changes and fibrosis levels in the myocardial tissue. Colorimetry was employed to detect serum Cu~(2+) concentration in rats. The levels of inflammatory cytokines interleukin-6(IL-6), interleukin-1β(IL-1β), interleukin-18(IL-18), tumor necrosis factor-α(TNF-α), as well as mitochondrial energy metabolites adenosine triphosphate(ATP), adenosine diphosphate(ADP), and adenosine monophosphate(AMP) in serum were measured using enzyme-linked immunosorbent assay(ELISA). Western blot was performed to detect the expression of collagen Ⅰ(Col-Ⅰ), collagen Ⅲ(Col-Ⅲ), and copper death-related proteins dihydrolipoamide acetyltransferase(DLAT), ferredoxin 1(FDX1), lipoic acid synthetase(LIAS), and heat shock protein 70(HSP70) in myocardial tissue. Immunofluorescence was used to detect the expression of DLAT, FDX1, and HSP70, while immunohistochemistry was conducted to examine the expressions of DLAT, FDX1, LIAS, and HSP70. The results showed that, compared to the model group, the myocardial structure disorder and collagen fiber deposition in the drug treatment groups were significantly improved, the cardiac index level was reduced, serum Cu~(2+), IL-6, IL-1β, IL-18, TNF-α, ADP, and AMP levels were significantly decreased, ATP levels were significantly increased, and the expressions of Col-Ⅰ, Col-Ⅲ, and HSP70 proteins in myocardial tissue were significantly reduced, while the expressions of DLAT, FDX1, and LIAS proteins were significantly elevated. In conclusion, Shenmai Injection effectively alleviates myocardial structure disorder and interstitial collagen fiber deposition in ISO-induced MF rats, promotes copper excretion, and reduces copper death in the ISO-induced rat MF model.

Chinese Journal of Lung Cancer 2025;28(4):256-266
BACKGROUND:
Lung adenocarcinoma (LUAD) is the predominant subtype of non-small cell lung cancer (NSCLC). Damage-specific DNA binding protein 1 (DDB1), as a core protein of the CUL4-DDB1 ubiquitin ligase complex, is involved in the regulation of DNA damage repair, epigenetic modification, and cell cycle checkpoint activation. While the involvement of DDB1 in tumour progression through DNA repair and RNA transcriptional regulation has been reported, its expression and role in LUAD remain to be elucidated. This study aims to investigate the expression and role of DDB1 in LUAD.
METHODS:
The expression, clinicopathological features and prognosis of DDB1 in LUAD were analysed using databases such as UALCAN, Kaplan-Meier Plotter and GEPIA; The interaction network and enriched functional pathways were constructed by GeneMANIA and Metascape; the correlation between DDB1 and immune cells by combining with TISIDB infiltration was evaluated, and the clustering results of cell subtypes and the expression of DDB1 in different immune cell subpopulations were analysed by single-cell sequencing; finally, tissue microarrays were used to further verify the expression and prognostic value of DDB1 in LUAD.
RESULTS:
The mRNA and protein expression of DDB1 in LUAD tissues were significantly higher than those in normal tissues (P<0.01), and the high expression correlated with later clinical stage (P<0.001), lymph node metastasis (P<0.001) and poor prognosis (P<0.001). Functional enrichment showed that DDB1 was involved in DNA repair and RNA transcriptional regulation, and TISIDB evaluation revealed that DDB1 was negatively correlated with the expression level of immune cells, suggesting the potential regulation of the immune microenvironment. Single cell analysis showed that DDB1 was mainly expressed in T cells, alveolar macrophages and dendritic cells. Tissue microarrays confirmed that overall survival was shorter in the DDB1 high expression group (P<0.001), and Cox multifactorial analysis showed that DDB1 was an independent predictor of LUAD prognosis.
CONCLUSIONS
DDB1 is highly expressed in LUAD, which is associated with poor prognosis, and is closely related to tumor immune cell infiltration, and is involved in tumourigenesis and development through DNA repair and RNA transcriptional regulation. DDB1 can be used as a potential prognostic marker and therapeutic target for LUAD.
