Inflammation is the body’s response to damage, infection or other stimuli, but its excessive or continuous development can lead to a variety of diseases. Although modern medical anti-inflammatory therapies were widely used, it is often accompanied by limitations such as more adverse reactions. Based on the “holistic view” and “differential treatment”, traditional Chinese medicine (TCM) regards inflammation as a manifestation of the imbalance of yin and yang in the body and the conflict between good and evil. The application of anti-inflammatory TCM is not only aimed at the pathological state of “inflammation”, but also based on the overall consideration of “syndrome”. According to different types of syndrome, anti-inflammatory TCM can be divided into heat-clearing and detoxifying agents (such as Lonicera japonica and Isatis indigotica ), heat-clearing and drying dampness agents (such as Coptidis Rhizoma), blood-activating and stasis-dissolving agents (such as Salvia miltiorrhiza ) and vital qi-strengthening and pathogenic factor-expelling agents (such as Panax ginseng ). Four types of anti-inflammatory TCM restore the body’s immune balance through the systematic regulation of multi-component, multi-target and multi-pathway, exhibiting a good anti-inflammatory effect. Future research should focus on integrating systematic biology, applying artificial intelligence, carrying out high-quality evidence-based research, and combining traditional Chinese medicine and Western medicine, so as to reveal the overall regulatory law of anti-inf lammatory effects of TCM and promote clinical rational use.

Objective: To summarize the laboratory findings of a case of hemolytic disease of the fetus and newborn (HDFN) caused by Rh system anti-c antibodies and to review the literature, so as to explore the characteristics of anti-c HDFN. Methods: The ABO blood type, Rh blood type, direct antiglobulin test (DAT) results, and the presence of unexpected antibodies and their titers were determined by serological methods. The cases of anti-c HDFN in our laboratory in China and abroad were statistically analyzed, and the incidence of severe HDFN caused by anti-c, anti-D and anti-E was compared. Results: The blood type of the child was B (Rh CcDee) with a positive DAT. Anti-c antibody was detected in both serum and eluate, with a serum antibody titer of 4. The mother’s blood type was AB (Rh CCDee) with a negative DAT, and anti-c antibody was detected in the serum with a titer of 128. Among 20 cases of anti-c HDFN, 17 were DAT positive, and 9 (45%, 9/20) underwent blood transfusion or exchange transfusion. The incidence of severe HDFN was 47.60% (10/21) for anti-c, 47.60% (10/21) for anti-D and 31.30% (5/16) for anti-E. Conclusion: Maternal pregnancy and/or blood transfusion are the main reasons for the production of Rh alloantibodies such as anti-c. The prevention and management of anti-c should be similar to that of anti-D. Rh antigen-matched (five antigens of Rh blood group) transfusion is necessary for women of childbearing age to avoid antibody production, and Rh typing and antibody screening during prenatal examination is recommended to ensure early detection, intervention and treatment.

Objective To investigate the factors influencing international normalized ratio (INR)>3.0 in patients undergoing warfarin anticoagulation therapy after mechanical heart valve replacement. Methods A retrospective analysis was performed on the clinical data of patients who underwent mechanical heart valve replacement surgery and received warfarin anticoagulation therapy at West China Hospital of Sichuan University from January 1, 2011 to June 30, 2022. Based on the discharge INR values, patients were divided into two groups: an INR≤3.0 group and an INR>3.0 group. The factors associated with INR>3.0 at the time of discharge were analyzed. Results A total of 8901 patients were enrolled, including 3409 males and 5492 females, with a median age of 49.3 (43.5, 55.6) years. The gender, body mass index (BMI), New York Heart Association (NYHA) cardiac function grading, INR, glutamic oxaloacetic transaminase, and preoperative prothrombin time (PT) were statistically different between the two groups (P<0.05). Multivariate logistic regression analysis revealed that lower BMI, preoperative PT>15 s, and mitral valve replacement were independent risk factors for INR>3.0 at discharge (P<0.05). Conclusion BMI, preoperative PT, and surgical site are factors influencing INR>3.0 at discharge in patients undergoing warfarin anticoagulation therapy after mechanical heart valve replacement. Special attention should be given to patients with lower BMI, longer preoperative PT, and mitral valve replacement to avoid excessive anticoagulation therapy.

ObjectiveTo investigate the efficacy and mechanism of Polygoni Cuspidati Rhizoma et Radix (Huzhang) in treating respiratory syncytial virus(RSV) infection by regulating pulmonary surfactant lipid homeostasis through lipidomics. MethodsSixty BALB/c mice were randomly divided into the blank group, model group, positive group(ribavirin group, 46 mg·kg-1), and low- and high-dose Huzhang groups(0.75, 2.25 g·kg-1), with 12 mice in each group. Except for the blank group, all other groups were infected with RSV via intranasal instillation. The drug intervention groups were given corresponding doses of drug by gavage for 3 consecutive days, while normal saline was used in the blank and model groups. Hematoxylin-eosin(HE) staining was used to observe pathological changes in mouse lung tissue. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was employed to detect viral loads[RSV-nucleoprotein(N) and RSV-glycoprotein(G) mRNA] and inflammatory factor levels[interleukin(IL)-1β and tumor necrosis factor(TNF)-α mRNA] in the lung tissue. Mouse bronchoalveolar lavage fluid was collected to detect the levels of pulmonary surfactant lipids through ultra-high performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap-MS), followed by principal component analysis and differential lipid identification. ResultsCompared with the blank group, the model group exhibited extensive inflammatory cell infiltration, congestion, and tissue damage in the lungs, and the pathological score and lung index of lung tissue significantly increased(P<0.01), along with significantly elevated mRNA expressions of RSV-N, RSV-G, IL-1β, and TNF-α(P<0.01). Compared with the model group, different doses of Huzhang and ribavirin significantly reduced the pathological scores of the lung tissue and lung index(P<0.01). In addition, the mRNA levels of RSV-N, RSV-G and TNF-α in the lungs significantly decreased in the Huzhang high dose group(P<0.01). Lipidomics analysis identified multiple significantly changed differential metabolites. Compared with the blank group, the model group showed obvious abnormal lipid metabolism, which was manifested by the elevated levels of prostaglandin(PG), ceramide(Cer), phosphatidylcholine(PC), phosphatidylethanolamine(PE), phosphatidylinositol(PI), sphingomyelin(SM), and the decreased levels of diglycerides(DG) and acylethanolamine(NAE). After the intervention of low dose of Huzhang, the above lipid metabolites showed a significant reversal trend, while the intervention of high dose of Huzhang could regulate levels of PI lipids, PG lipids and PC lipids. ConclusionHuzhang can significantly reduce the viral load of lung tissue and improve lung inflammation in RSV-infected mice. The underlying mechanism may be related to the maintenance of homeostasis in pulmonary surfactant lipids such as PI and PG.

ObjectiveTo observe and analyze the plasma metabolite differences among colorectal cancer patients with spleen-qi deficiency, damp-heat stasis-toxin syndrome(SRYD), non-spleen-qi deficiency, damp-heat stasis-toxin syndrome(non-SRYD), and normal human beings(Normal), aiming to identify unique metabolites specific to SRYD colorectal cancer patients and their potential biomarkers. MethodsBased on the diagnostic criteria of SRYD and non-SRYD colorectal cancer, 30 patients were included, including 10 patients with SRYD colorectal cancer and 20 patients with non-SRYD colorectal cancer, while 10 individuals were recruited for the Normal group. Metabolome sequencing of plasma from the three groups was performed by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap mass spectrometry(UPLC-Q-Exactive-Orbitrap-MS). Multivariate statistical analysis were performed by principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA), and the intergroup differential metabolites were identified based on variable importance in the projection(VIP) value>1 and t-test P<0.05. And pathway enrichment analysis based on Kyoto Encyclopedia of Genes and Genomes(KEGG) was performed to explore the metabolites and metabolic pathways specific to SRYD colorectal cancer patients. ResultsMetabolome sequencing results showed some differences in metabolic profiles between the groups. A total of 111 plasma differential metabolites were found in the SRYD group and the Normal group, of which 31 were up-regulated and 80 were down-regulated, mainly including stearoyl lysophosphatidylcholine, indole-3-acrylic acid, and dehydroepiandrosterone sulfate(P<0.05). The non-SRYD group exhibited 97 differentially expressed metabolites compared to the Normal group, with 36 up-regulated and 61 down-regulated, mainly including stearoyl lysophosphatidylcholine, sphingosine, and palmitoyl lysophosphatidylcholine(P<0.05). And the SRYD group exhibited 19 differentially expressed metabolites compared to the non-SRYD group, of which 5 were up-regulated and 14 were down-regulated, mainly including dihydrosphingosine, palmitic acid, and linoleoylethanolamide(P<0.05). The significant differential metabolites were subjected to KEGG analysis to obtain significantly enriched metabolic pathways in each group, and the results showed that 11 metabolic pathways such as primary bile acid synthesis, cholesterol metabolism and bile secretion were differential signaling pathways specific to SRYD colorectal cancer. Further retrieval of the above key signaling pathways showed that bile acids were up-regulated in both bile secretion and primary bile acid synthesis pathways, and there was a trend of up-regulation of glycochenodeoxycholic acid, taurochenodeoxycholic acid, and chenodeoxycholic acid. ConclusionPrimary bile acid synthesis, cholesterol metabolism, and bile secretion-related pathways may be differential signaling pathways specific to SRYD colorectal cancer, and bile acid is a core molecule in the metabolic pathway, which can serve as potential biomarkers closely related to the development and progression of SRYD colorectal cancer.

BACKGROUND:
Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS.
METHODS:
This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide.
RESULTS:
Eighty-two patients were assigned to variant ( n = 42) and wild type groups ( n = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study.
CONCLUSION:
ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

BACKGROUND:
While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients.
METHODS:
This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively.
RESULTS:
The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge.
CONCLUSION
Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

The study aims to examine the effects and potential mechanisms of disulfiram (DSF) on cardiac hypertrophic injury, focusing on the role of transforming growth factor-β-activated kinase 1 (TAK1)-mediated pan-apoptosis (PANoptosis). H9C2 cardiomyocytes were treated with angiotensin II (Ang II, 1 µmol/L) to establish an in vitro model of myocardial hypertrophy. DSF (40 µmol/L) was used to treat cardiomyocyte hypertrophic injury models, either along or in combination with the TAK1 inhibitor, 5z-7-oxozeaenol (5z-7, 0.1 µmol/L). We assessed cell damage using propidium iodide (PI) staining, measured cell viability with CCK8 assay, quantified inflammatory factor levels in cell culture media via ELISA, detected TAK1 and RIPK1 binding rates using immunoprecipitation, and analyzed the protein expression levels of key proteins in the TAK1-mediated PANoptosis pathway using Western blot. In addition, the surface area of cardiomyocytes was measured with Phalloidin staining. The results showed that Ang II significantly reduced the cellular viability of H9C2 cardiomyocytes and the binding rate of TAK1 and RIPK1, significantly increased the surface area of H9C2 cardiomyocytes, PI staining positive rate, levels of inflammatory factors [interleukin-1β (IL-1β), IL-18, and tumor necrosis factor α (TNF-α)] in cell culture media and p-TAK1/TAK1 ratio, and significantly up-regulated key proteins in the PANoptosis pathway [pyroptosis-related proteins NLRP3, Caspase-1 (p20), and GSDMD-N (p30), apoptosis-related proteins Caspase-3 (p17), Caspase-7 (p20), and Caspase-8 (p18), as well as necroptosis-related proteins p-MLKL, RIPK1, and RIPK3]. DSF significantly reversed the above changes induced by Ang II. Both 5z-7 and exogenous IL-1β weakened these cardioprotective effects of DSF. These results suggest that DSF may alleviate cardiac hypertrophic injury by inhibiting TAK1-mediated PANoptosis.
