With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

Biomolecular condensates are formed through phase separation of biomacromolecules such as proteins and RNAs. These condensates exhibit liquid-like properties that can futher transition into more stable material states. They form complex internal structures via multivalent weak interactions, enabling precise spatiotemporal regulations. However, the use of inconsistent and non-standardized terminology has become increasingly problematic, hindering academic exchange and the dissemination of scientific knowledge. Therefore, it is necessary to discuss the terminology related to biomolecular condensates in order to clarify concepts, promote interdisciplinary cooperation, enhance research efficiency, and support the healthy development of this field.

ObjectiveTo analyze the impact of maternal postpartum depression (PPD) at 2 months postpartum on caregiving for infants aged2 to 24 months, and to provide a scientific basis for future maternal and infant healthcare services. MethodsBased on the Shanghai Maternal-Child Pairs Cohort, 1 060 mother-child pairs were selected from those fully participating in follow-up visits at 2, 6, 12, and 24 months postpartum. Pregnancy and childbirth-related information was collected using standardized questionnaire surveys and hospital obstetric and maternity records. The Edinburgh postpartum depression scale was used to assess the maternal postpartum depressive symptoms at 2 months postpartum. At 2, 6, 12, and 24 months postpartum, questionnaire survey was used to evaluate the maternal responsiveness in caregiving and the provision of early learning opportunities for infants. Scores for responsive caregiving and early learning opportunities at 2, 6, 12, and 24 months were grouped based on the 25th percentile (P₂₅) of total scores. The mixed-effects model was used to analyze the longitudinal impact of maternal postpartum depression at 2 months on the caregiving of 2 to 24-month-old infants. ResultsThe longitudinal results from the mixed-effects model did not show an impact of maternal PPD on infant responsive caregiving within 12 months and early learning opportunities within24 months. However, cross-sectional analysis revealed that, compared to the non-PPD group, the risk of low responsive caregiving at 2 months in the PPD group was 93% higher (OR=1.931, 95%CI: 1.113‒3.364, P=0.019). The risks for low provision of early learning opportunities at2 months and 24 months increased by 59% (OR=1.589, 95%CI: 1.082‒2.324, P=0.017) and 60% (OR=1.598, 95%CI:1.120‒2.279, P=0.010), respectively. ConclusionMaternal postpartum depression increases the risk of low responsive caregiving at 2 months, but its long-term effects warrant further research.

Hepatolenticular degeneration， also known as Wilson disease （WD）， is a hereditary disease caused by mutations in the ATP7B gene， leading to copper metabolism disorders. Gene mutations result in impaired synthesis of copper-binding protein， and abnormal excretion of copper through bile leads to pathological deposition of copper in various organs， ultimately causing multi-organ damage. The insidious onset and low specificity of symptoms make it difficult to diagnose this disease. On the basis of existing studies and the theory of latent toxin， this paper proposes that latent toxin in kidney collaterals is the main pathogenesis of renal injury in WD. It is pointed out that health Qi deficiency and latent pathogen are the premises for the occurrence of this disease， and the transformation of latent pathogen into toxin is the ley pathological process. Toxin damaging kidney collaterals is the ultimate result. According to the pathogenesis， this paper proposes the treatment principle of reinforcing healthy Qi and resolving toxin and treatment based on syndrome differentiation. This review provides new ideas for the diagnosis and treatment of renal injury in WD with traditional Chinese medicine.

ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with neuromuscular electrical stimulation （NMES） in the treatment of dysphagia in Wilson disease （WD） with combined phlegm and stasis. MethodsA total of 80 WD patients with dysphagia due to combined phlegm and stasis treated in the Department of Encephalopathy， the First Affiliated Hospital of Anhui University of Chinese Medicine were randomized into a control group and an observation group， with 40 patients in each group. In addition， 40 healthy volunteers were recruited as the normal group. The control group was treated with basic copper drainage combined with NMES. The observation group was treated with Gandouling Decoction on the basis of the therapy in the control group. Each course of treatment lasted for 8 days， and the patients were treated for a total of 4 courses. All subjects underwent video fluoroscopic swallowing study （VFSS） before and after treatment. During the examination， contrast agents with 4 different characters were used for the swallowing action， and the passing time was recorded. The TCM syndrome score， water swallow test score， standard swallowing assessment （SSA） score， and 24-h urinary copper level before and after treatment were analyzed. ResultsWhen performing VFSS， the passing time of contrast agents of different characters in the oral stage was longer in the WD group than in the normal group （P<0.01）， while it had no significant difference in the pharyngeal stage. After treatment， the passing time in the oral stage shortened in the control and observation groups （P<0.01）， and the observation group outperformed the control group （P<0.01）. After treatment， both the control and observation groups showed declines in TCM syndrome score and SSA score （P<0.01） and an increase in water swallow test score （P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.01）. In addition， the treatment in the control and observation groups elevated the 24-h urinary copper level （P<0.01）， and the elevation in the observation group was more obvious than that in the control group （P<0.01）. Neither group showed obvious adverse reaction. ConclusionGandouling decoction combined with NMES can significantly ameliorate dysphagia in WD patients with the syndrome of combined phlegm and stasis regarding the TCM syndrome score， water swallow test score， and SSA score， demonstrating definite clinical efficacy and high safety.

Wilson disease is a copper metabolism disorder caused by mutations in the ATP7B gene， which encodes a copper-transporting ATPase β， and can result in multisystem damage. The kidneys are the third most commonly affected organs after the liver and brain. In recent years， numerous diagnostic and treatment guidelines for Wilson disease have emerged. However， most of these focus primarily on hepatic and neurological manifestations and their management， with limited coverage of renal involvement. The high incidence， low awareness， and lack of clinical specificity of Wilson disease-related renal damage （WDRD） have made early detection and intervention particularly challenging in clinical practice. To further optimize the treatment of patients with WDRD， improve clinical diagnosis and management， and enhance patients' quality of life， the Neurology Committee of the Chinese Association of Integrative Medicine， in April 2024， initiated a revision of the first expert consensus on the integrated diagnosis， treatment， and management of WDRD. This effort brought together experts in hepatology， encephalopathy （neurology）， and nephrology from many tertiary-level grade A hospitals and research institutions across China. Through comprehensive literature review and integration of frontline clinical experience， the expert group jointly developed Chinese Expert Consensus on Integrated Chinese and Western Medicine Management of Wilson Disease-related Renal Damage （hereinafter referred to as the "Consensus"）. This article provides a detailed interpretation of the Consensus in terms of diagnostic criteria， traditional Chinese medicine （TCM） syndrome differentiation and treatment classification， and comprehensive disease management， aiming to better guide clinical application. Regarding diagnostic criteria， the Consensus integrates the latest standards in China and abroad， highlights the importance of biochemical diagnosis， and compensates for the limitations of genetic testing. In the area of TCM syndrome differentiation and treatment， the Consensus refines four major syndrome types， introduces a newly defined syndrome， i.e.， phlegm， blood stasis， and heat accumulation， and elaborates on treatment principles， prescriptions， and clinical modification rules for each syndrome. For comprehensive disease management， the Consensus emphasizes multi-dimensional intervention strategies， including diet， exercise， emotional regulation， medication， and medical care， with the goal of maximally controlling the progression of renal dysfunction and helping patients achieve a better quality of life.

"MS/MS spectrum to structure"plays a critical role in the confirmative identification of complicated matrices and is currently regarded as an extremely challenging endeavor.MS/MS information provides vital clues to structural identification.In this study,a strategy was proposed to facilitate unambiguous identification through matching MS3 with MS2 spectra.Initially,MS3 spectra of the featured ions(c-and y-type ions)generated by the decomposition of ester functional group in esters and the MS2 spectrum of the structural unit([M-H]-)were all captured on the Qtrap-MS platform equipped with two tandem-in-space collision cells,including the second quadrupole cell(q2)and linear ion trap(LIT)chambers(actually the third quadrupole unit).Subsequently,the MS/MS spectrum matching between MS3 spectra of the ester compound and MS2 spectra of the structural unit(s)were achieved.As a result,the findings corresponding to MS3 and MS2 spectra matching were summarized.Finally,based on HR-MS/MS information of total salvianolic acid derivatives(TSA),36 kinds of compounds were preliminarily identified through matching with literature information and database retrieval.The applicability of MS3 and MS2 spectra matching strategy was further justified by the confirmative identification of phenolic acid compounds(Rosmarinic acid and salvianolic acid B)in TSA.Above all,MS3 and MS2 spectra matching strategy was quite meaningful towards advancing"MS/MS spectrum to structure"analysis through recognizing and identifying featured fragment ions,and also provided inspiration and new insights for the structural characterization.

Objective To explore the clinical significance of nucleolar antinuclear antibodies(ANA)in re-lated diseases.Methods This study was a retrospective study.Clinical samples of 71780 patients who visited the hospital from January 2017 to May 2022 were collected.Indirect immunofluorescence was used to detect ANA in clinical samples.Statistical analysis was conducted on the positivity rate of nucleolar ANA in clinical patients,as well as the relevant clinical information and laboratory characteristics of patients with autoimmune diseases(AID)with nucleolar ANA positivity.Results Among 71780 patients who underwent routine ANA testing,16778 were positive for ANA,with a positive rate of 23.37％.Among them,there were 1 708 cases of nucleolar type,accounting for 2.38％of all routine ANA tests,and the proportion of ANA positive cases was 10.18％.There was a statistically significant difference in the positive rate of nucleolar ANA between patients of different genders in the＞20-＜50 year old group and the ≥ 50 year old group(P＜0.05),while there was no statistically significant difference in the positive rate of nucleolar ANA between patients of different genders in the ≤ 20 year old group(P＞0.05).There was a statistically significant difference in the positivity rate of nucleolar ANA among women of different age groups(P＜0.05),among them,the highest positive rate of nucleolar ANA was found in women aged between 20 and 50 years old.There was no statistically significant difference in the positive rate of nucleolar ANA among males of different age groups(P＞0.05).The positivi-ty rate of ANA was the highest among patients in the Department of Rheumatology and Immunology(70.35％),but nucleolar ANA positivity was mainly seen in departments such as Reproductive Medicine Cen-ter(12.90％),Respiratory Medicine(12.40％),and Neurology(11.29％),and the difference in positivity rates between departments was statistically significant(P＜0.05).Out of 1 708 nucleolar ANA positive indi-viduals,420 underwent ANA titers,including 34 AID patients and 386 non AID patients.There was no statis-tically significant difference in nucleolus positive titers between non AID patients and AID patients(P＞0.05).Conclusion The nucleolus type is a common fluorescence pattern in ANA positive individuals,and there are gender and age differences in ANA positive individuals.The positive rate and titer of nucleolar ANA vary among different AID diseases.Combined with other immune function indicators,and it is helpful for early differential diagnosis of AID.

Objective To explore the efficacy of a new anti-heart failure drug,Entresto,in the prevention of cardiotoxicity caused by doxorubicin(DOX).Methods Male adult ICR mice were randomly divided into three groups(n = 8):control group,DOX group and DOX plus Entresto group.Cardiac function of mice was measured by echocardiography.H9c2 cells were pretreated with Entresto(0-48 μmol/L)for 24 hours in the presence or absence of DOX(1 mmol/L),and then cell viability,oxidative stress,apoptosis and mitochondrial function were evaluated.Results As compared with the control group,leakage of CK,CK-MB and LDH increased significantly in the DOX group(P<0.01),and left ventricular systolic dysfunction occurred.Entresto administration reversed these changes in the DOX group.The level of ROS and the number of apoptotic cells in cardiomyocytes in the DOX plus Entresto group were lower than those in the DOX group(P<0.05).As compared with the DOX group,the level of ROS and the number of apoptotic cells in H9c2 cells decreased significantly in the Entresto plus DOX group(P<0.05),and mitochondrial membrane potential increased significantly(P<0.05).Entresto reversed the inhibitory effect of DOX on SIRT1/PGC-1α/MFN2 signaling pathway.Conclusions Entresto improves DOX-induced cardiotoxicity by inhibiting ROS-mediated oxidative stress and apoptosis,and its mechanism may be related to SIRT1/PGC-1α/MFN2 signal transduction pathway.

ObjectiveTo clarify the relationship between intestinal flora and intestinal motility in rats with slow transit constipation （STC） and qi stagnation syndrome by conducting a pseudo-sterile experiment and fecal microbiota transplantation （FMT） technology. MethodsTwenty-four Wistar rats were randomly divided into normal group （n=6）， STC with qi stagnation pattern group （n=6） and pseudo-sterile group （n=12）. In the STC group with qi stagnation pattern， 3 mg/kg of loperamide suspension by intragastric administration combined with tail clamping stimulation were performed to establish the rat model of STC with qi stagnation pattern. After successful modeling， fresh feces from the rats in the STC with qi stagnation pattern group and the normal group were collected to prepare 100 mg/ml of fecal bacterial suspension. In the pseudo-sterile group， the antibiotic cocktail method was used （a mixed antibiotic suspension containing bacitracin， streptomycin sulfate， and neomycin sulfate at 20 mg/ml each was administered intragastrically） to establish pseudo-sterile rats model. After successful modeling， the rats were randomly divided into normal fecal bacterial liquid group and STC with qi stagnation pattern fecal bacterial liquid group， with six rats in each group， and then were given 10 ml/kg of the prepared corresponding rat fecal bacterial suspension by gavage. Rats in STC with qi stagnation pattern group were given an equal volume of sterile water by gavage. All groups were administered once a day for 7 consecutive days. The small intestinal propulsion rate of the STC with qi stagnation pattern group， the normal fecal bacterial liquid group， and STC with qi stagnation pattern fecal bacterial liquid group were compared. ELISA method was used to detect serum 5-hydroxytryptamine （5-HT） levels. Immunohistochemistry was used to detect the positive expression levels of 5-hydroxytryptamine 3 receptor （5-HT3R） and 5-hydroxytryptamine 4 receptor （5-HT4R） in colon tissue. Western blot method was used to detect the protein expression levels of tryptophan hydroxylase 1 （TPH1）， tryptophan hydroxylase 2 （TPH2）， serotonin transporter （SERT）， and monoamine oxidase A （MAO-A） in colon tissue. ResultsCompared to those in the normal fecal bacterial liquid group， the small intestinal propulsion rate， serum 5-HT level， positive expression of 5-HT3R and 5-HT4R in colon tissue， and protein expression of TPH1， TPH2， SERT and MAO-A significantly decreased in the STC with qi stagnation pattern group and STC with qi stagnation pattern fecal bacterial liquid group （P＜0.05）. There was no statistically significant difference in the indicators between the STC with qi stagnation pattern group and STC with qi stagnation pattern fecal bacterial liquid group （P＞0.05）. ConclusionThe intestinal flora in STC rats with qi stagnation pattern can lead to a slowdown in intestinal transmission function， whose mechanism may be related to intestinal motility disorders affected by the synthesis， transport， metabolism and other pathways of 5-HT.
