ObjectiveTo establish a quality evaluation method for Zhuye Shigao granules（Zhuye Shigaotang） based on fingerprint and determination of index components， and to investigate the therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome. MethodsThe fingerprint of Zhuye Shigao granules was established by high performance liquid chromatography（HPLC）， and the methods for determination of total calcium， orientin， isoorientin， ginsenosides Rg₁， Re and Rb₁ and other 2 index components were established. Fifty ICR mice were randomly divided into the blank group， model group， Zhuye Shigao granules low， medium and high dose groups（9.3， 18.6， 37.2 g·kg^-1·d^-1）， with 10 mice in each group. In addition to the blank group， the model mice with cold-dampness pestilence attacking lung syndrome was prepared by nasal drip of lipopolysaccharide combined with cold-dampness environment. Each administration group was given the corresponding liquid by gavage according to the dose， while the blank group and model group were given the same volume of normal saline by gavage. Then， the body temperature and organ index of mice in each group were measured， hematoxylin-eosin（HE） staining was used to investigate the lung tissue injury of mice in each group， and enzyme-linked immunosorbent assay（ELISA） was used to detect the changes of tumor necrosis factor-α（TNF-α）， interleukin（IL）-lβ， IL-6， IL-10 levels in serum and lung tissue， as well as immunoglobulin（Ig）A and IgM levels in serum. ResultsThe fingerprint similarity of 10 batches of Zhuye Shigao granules was>0.950， and 20 common peaks were calibrated. Seven of them were identified， including peak 11（isoorientin）， peak 12（orientin）， peak 14（apioside liquiritin）， peak 15（liquiritin）， peak 17（apioside isoliquiritin）， peak 19（isoliquiritin） and peak 20（liquiritigenin）. The results of quantitative analysis showed that the content range of each index component in 10 batches of Zhuye Shigao granules was as follows：Total calcium of 9.978-11.294 mg·g^-1， isoorientin of 0.033-0.041 mg·g^-1， orientin of 0.046-0.055 mg·g^-1， ginsenoside Rg₁+ginsenoside Re of 0.748-0.762 mg·g^-1， ginsenoside Rb₁ of 0.151-0.197 mg·g^-1， liquiritin of 1.106-1.366 mg·g^-1， glycyrrhizic acid of 0.904-1.182 mg·g^-1_. Compared with the blank group， the body temperature of mice in the model group was significantly increased， the organ indexes of liver， lung and spleen were significantly decreased， the organ index of thymus was significantly increased， HE staining of lung tissue showed infiltration of inflammatory cells， a small amount of serous exudation was observed in the alveoli， and lung tissue was damaged. After the intervention of Zhuye Shigao granules， the pathological changes were improved compared with the model group. The expression levels of IL-1β， IL-6 and TNF-α were significantly increased， the expression level of IL-10 was significantly decreased in serum and lung tissue. The levels of IgA and IgM in serum were significantly decreased（P<0.01）. Compared with the model group， the body temperature， the organ indexes and immune factor levels in serum and lung tissue of mice in the Zhuye Shigao granules medium and high dose groups were significantly reduced（P<0.05， P<0.01）. ConclusionIn this study， the quality evaluation of Zhuye Shigao granules was carried out based on fingerprint combined with determination of index components， and the fingerprint of four herbs（Lophatheri Herba， Ophiopogonis Radix， Pinelliae Rhizoma and Glycyrrhizae Radix et Rhizoma） in this formula and the determination of 8 index components were established. The therapeutic effect of Zhuye Shigao granules on mice with cold-dampness pestilence attacking lung syndrome may be related to inhibiting inflammatory response and mediating immune regulation.

Objective: To evaluate the performance of platelet efficacy score (PEscore) in predicting platelet transfusion efficacy in hematological patients. Methods: A total of 485 patients with hematological diseases, including 298 males (62.09±15.45 years) and 187 females (59.17±16.52 years) who received platelet transfusion from January 1, 2021 to December 31, 2024 were enrolled in this study. Clinical data of the patients such as diagnosis, gender, age, number of platelet transfusion, and platelet antibody data were analyzed to investigate the incidence and influencing factors of platelet transfusion refractoriness in hematological patients at our hospital. ROC curve was used to evaluate the performance of PEscore model in predicting platelet transfusion efficacy. The predictive performance of PEscore model was validated by calculating its sensitivity, specificity, and accuracy in 115 clinical cases. Results: The incidence of platelet transfusion refractoriness in 485 cases was 29.90% (145/485). Significant differences (P<0.05) were observed between the effective and ineffective platelet transfusion groups regarding the following factors: diagnosis: lymphoma [55.32% (26/47) vs 44.68% (21/47)], the number of previous platelet transfusions [≥25: 60.78% (31/51) vs 39.22% (20/51)], platelet antibody screening result [positive: 33.76% (53/157) vs 66.24% (104/157)], and platelet transfusion volume (×10 /L) [>6: 62.71% (74/118) vs 37.29% (44/118)]. The area under the ROC curve of PEscore was 0.876. The cut-off points and corresponding sensitivity and specificity were 19.90.59% and 69.44%, respectively. The results of clinical application showed that the sensitivity, specificity and accuracy of the PEscore model for predicting platelet transfusion were 87.50%, 93.41% and 92.17%, respectively. Conclusion: The incidence of platelet transfusion refractoriness in hematological patients is relatively high. PEscore prediction model has a good performance in predicting the effect of platelet transfusion, which can provide a reliable basis for predicting the effect of platelet transfusion in hematological patients before blood transfusion.

Objectives:To investigate the predictive value of epicardial fat volume(EFV)and atrioventricular groove fat thickness(AVGT)—morphological biomarkers of epicardial adipose tissue—for major adverse cardiovascular events(MACE)in patients with dilated cardiomyopathy(DCM).Methods:This study enrolled 216 DCM patients.EFV and AVGT were obtained from cardiac magnetic resonance imaging(CMR).Patients were divided into event-free group(n=142)and event group(n=74)based on MACE occurrence during follow-up.Receiver operating characteristic(ROC)curve analysis was used to determine optimal cutoff values.Survival differences were assessed using Kaplan-Meier analysis,Cox proportional hazards regression analysis was used to identify independent risk factors,and restricted cubic spline(RCS)models were used to evaluate dose-response relationships.Results:AVGT and EFV were significantly higher in the event group than in event-free group(both P<0.05).ROC analysis identified optimal MACE-predicting cutoffs as follows:AVGT≥7.74 mm(area under the curve[AUC]=0.57)and EFV≥78.6 ml(AUC=0.62).Kaplan-Meier analysis revealed significantly lower MACE-free survival rates in patients with AVGT≥7.74 mm and EFV≥78.6 ml(both P<0.05).Cox regression analysis confirmed that AVGT(HR=2.18,95%CI:1.34-3.54)and EFV(HR=1.81,95%CI:1.11-2.96)were independent MACE risk factors(both P<0.05)in this patient cohort.RCS models demonstrated the significant linear associations between EFV/AVGT and MACE risk(bothoverall P<0.05).Conclusions:EFV and AVGT,the non-invasive imaging biomarkers quantifying and characterizing fat distribution,are independently correlated with elevated MACE risk in DCM patients.These metrics serve as potential prognostic indicators,enriching risk stratification indicators for early identification of high-risk patients and guiding personalized medication strategies.

Glioma is the most common primary tumor of the central nervous system,with glio-blastoma multiforme of World Health Organization grade Ⅳ exhibiting the highest malignancy and worst prognosis.Long non-coding RNA(lncRNA)is a type of regulatory RNA without protein-coding ability,which can promote the malignant phenotypic evolution of glioma cells and induce therapeutic resistance by reprogramming glycolytic metabolism,playing a crucial role in the malignant progression and prognosis of glioma.This paper mainly introduced the role of lncRNA in regulating the biological behavior of glioma cells and aerobic glycolysis,and proposed a new paradigm of combined therapy based on the aerobic glycolysis metabolism-epigenetic network,providing new ideas for the discovery of diagnostic biomarkers and the development of novel therapeutic strategies for glioma.

Objective To explore the effect of electromyographic perception-assisted robotic training combined with paired associa-tion stimulation on upper limb function in hemiplegic patients after stroke.Methods From December,2023 to December,2024,120 hemiplegic patients after stroke in Nanjing Pukou People's Hos-pital(Liangjiang Hospital,Southeast University)were randomly assigned to control group(n=60)and experi-mental group(n=60)using random envelope method.Both groups received medication and routine rehabilita-tion training,the control group received traditional muscle strength training combined with paired associative stimulation,and the experimental group received electromyographic perception robot-assisted training combined with paired association stimulation.Fugl-Meyer Assessment-Upper Extremities(FMA-UE),modified Barthel In-dex(MBI),and modified Ashworth Scale(MAS)were conducted before and four weeks after treatment.The sur-face electromyography(sEMG)was used to detect the root mean square(RMS)and integrated electromyography(iEMG)of the biceps and triceps brachii,and to calculate the corresponding co-activation ratio(CR).Results Nine cases in the control group and four cases in the experimental group dropped down.After treatment,RMS of triceps,CR of flexion elbow,the scores of FMA-UE and MBI increased in both groups(|t|>2.219,P<0.001),and were better in the experimental group than in the control group(|t|>2.084,P<0.05);the biceps RMS and CR of elbow extension significantly increased in experimental group(|t|>3.863,P<0.001),and were better in the experimental group than in the control group(|t|>2.498,P<0.05).The MAS score of biceps improved in experi-mental group after treatment(Z=-4.097,P<0.001),and was better in the experimental group than in the con-trol group(Z=-3.459,P<0.01).Conclusion Electromyographic perception robot-assisted training combined with paired association stimulation can im-prove the upper limb motor function and the ability of daily living in hemiplegic patients after stroke.

Objective To present an assessment method based on oscillometric upper-arm cuff pressure wave for realizing home-based detection of arteriosclerosis.Methods An upper-arm cuff pressure wave acquisition device based on an electronic blood pressure monitor was designed to implement data collection for cuff inflation and deflation,as well as the 15 s pressure holding phase.Following preprocessing of the data collected during this holding phase,individual pulse waves were extracted for pulse decomposition analysis(PDA).A novel model that superimposed a logarithmic normal function with two Gaussian functions,and an optimization method that combined template matching and particle swarm optimization were proposed to efficiently and accurately extract PDA features.Gaussian process regression was employed for multifeature fusion analysis,leading to the proposal of a new predictive indicator for arteriosclerosis.Results The mean absolute error of PDA was less than 1.2%,and the average processing time for a single pulse wave was less than 0.2 s.The regression determination coefficient R2 between the obtained indicators and baPWV was 0.8178.Conclusion The analysis on upper-arm cuff pressure wave provides a new reference for non-invasive arteriosclerosis detection,and it can be applied to electronic blood pressure monitors for home-based monitoring,offering significant practical value.

In the context of global climate change, the impact of ambient temperature change on cardiovascular health has become increasingly significant. Epidemiological studies have shown that both high and low temperature can lead to the occurrence of adverse cardiovascular outcomes. For example, exposure to low temperature and high temperature, and diurnal temperature difference can increase the risk of cardiovascular diseases (CVD) mortality. Exposure to cold and heat, heatwaves and cold spells may induce myocardial infarction. Low temperature, high temperature and variations in temperature can increase the risk of heart failure. There are complex interactions among the effects of temperature and humidity, wind speed, radiation, precipitation and air pollution on adverse cardiovascular outcomes. Valnerable groups such as the elderly, patients with chronic diseases, and outdoor workers are particularly susceptible to temperature-related CVD risks. The mechanisms by which temperature affects adverse cardiovascular outcomes involves hemodynamic changes, autonomic nervous system dysregulation, blood rheology alterations, as well as inflammation and metabolic abnormalities, but many research gaps remain. Future studies should conduct in-depth research on mechanisms, individual differences, climate change impacts, and public health interventions to provide more effective policies and interventions to reduce the burden of CVD.

The diagnosis rate of early breast cancer has significantly increased with the proliferation of tumor screening and heightened health awareness.Clinical research,as the evidence base for guidelines and consensus,provides optimized treatment plans for breast cancer.This article summarized and classified several pivotal clinical studies that changed the clinical practice of early breast cancer,according to updates in domestic and international guidelines and consensus from 2023 to 2024.These included the optimization of neoadjuvant and adjuvant therapies,the escalation of adjuvant endocrine therapy,the optimization of local treatment,and attention to quality of life,etc.In the optimization of neoadjuvant and adjuvant therapies,the KEYNOTE-522 study established the therapeutic role of pembrolizumab combined with chemotherapy in early high-risk triple-negative breast cancer(TNBC).The FDChina study confirmed the non-inferiority of the subcutaneous formulation of trastuzumab combined with pertuzumab(H+P)in neoadjuvant treatment of human epidermal growth factor receptor 2(HER2)-positive breast cancer,offering a more convenient administration method.The KATHERINE study clarified the adjuvant role of trastuzumab emtansine(T-DM1)in HER2-positive breast cancer patients who did not achieve a pathologic complete response(pCR)after neoadjuvant therapy.In the escalation of adjuvant endocrine therapy,the MonarchE and NATALEE studies confirmed the efficacy of abemaciclib and ribociclib combined with endocrine therapy in high-risk hormone receptor(HR)-positive HER2-negative early breast cancer patients,promoting the application of cyclin-dependent kinase(CDK)4/6 inhibitors in early breast cancer treatment.In the optimization of local treatment,the ACOSOG Z11102 study supported the feasibility of breast-conserving surgery for multicentric breast cancer,the SENOMAC study provided evidence for exempting sentinel lymph node(SLN)low-burden breast cancer patients from axillary lymph node dissection(ALND),the SOUND study supported the exemption of sentinel lymph node biopsy(SLNB)for T1 and cN0 breast cancer patients,and the ICARO study suggested the feasibility of exempting ALND for patients with isolated tumor cells(ITCs)found after neoadjuvant chemotherapy with SLNB or targeted axillary dissection(TAD).The NSABP B-51/RTOG 1304 study provided a basis for the de-escalation of regional lymph node irradiation(RNI)and local treatment in ypN0 breast cancer after neoadjuvant therapy.In terms of quality of life and chemoprevention,the POSITIVE study proposed a protocol for pausing endocrine therapy for breast cancer patients with fertility needs,and the TAM-01 and IBIS-Ⅱ studies provided strong evidence-based medical evidence for chemoprevention in high-risk breast cancer patients.These pivotal clinical studies have profoundly impacted the clinical practice of early-stage breast cancer,not only optimizing treatment plans but also focusing on the quality of life and disease prevention of breast cancer patients.This article discussed the impact of the aforementioned clinical studies on the clinical practice of early breast cancer,centered on updates to various domestic and international breast cancer diagnosis and treatment guidelines and consensus.
