This paper summarizes Professor WANG Xixing's clinical experience in treating immune checkpoint inhibitor-related pneumonitis （CIP） based on the theory of "cough attributed to the five zang （脏） organs". Cough is a common predominant symptom of CIP. According to the theory of "cough attributed to the five zang organs"， drug toxicity triggers cancer toxin， leading to disharmony among the five zang organs， and then lung failing to diffuse and govern descent as the core pathogenesis. Therefore， treatment should focus on harmonizing the five zang organs to restore the normal function of lung qi to diffuse and govern descent. In clinical practice， CIP can be classified into four syndrome patterns， including lung yin depletion， deficiency of both the lung and the spleen with phlegm-dampness， liver fire harassing the lung， and lung-kidney yin deficiency. Correspondingly， Chaimai Jinluo Runfei Decoction （柴麦金络润肺汤） is used to nourish yin and moisten the lung； Qigui Peitu Huayin Decoction （芪桂培土化饮汤） is used to fortify the spleen and tonify the lung， resolve dampness and dispel phlegm； Chaidan Shuyu Runjin Decoction （柴丹疏郁润金汤） is used to drain liver and clear the lung； and Dimai Jinshui Xiangsheng Decoction （地脉金水相生汤） is used to nourish the kidney and moisten the lung.

Primary liver cancer is one of the most common causes of cancer-related deaths in China,with hepatocellular carcinoma(HCC)accounting for 75%-85%.Approximately 70%of HCC patients are in the advanced stage at the time of diagnosis and miss the opportunity for radical surgery,leading to a poor prognosis.Yttrium-90 microsphere selective internal radiation therapy(90Y-SIRT),an emerging therapeutic modality,delivers radioactive microspheres via the hepatic artery to target tumors and uses beta radiation for localized tumor ablation.Compared to conventional transarterial chemoembolization and pharmacotherapy,90Y-SIRT shows the advan-tages of significant clinical benefits,good safety profiles,and broad applicability across diverse patient populations.This article re-views the advances in the application of 90Y-SIRT in HCC treatment.

Objective To investigate the current status of acceptance of disability(AOD)among young and middle-aged spinal cord injury patients and analyze the factors influencing it,in order to provide a basis for nursing managers to develop targeted interventions.Methods From February to July 2024,a convenience sample of 330 young and middle-aged spinal cord injury patients who were hospitalized in 3 tertiary-level hospitals in Henan Province was selected.The survey was conducted using a general information questionnaire,the Brief Adaptation to Disability Scale-Revised,Perceived Social Support Scale,Connor-Davidson Resilience Scale-10 item,Brief Illness Perception Questionnaire,Medical Coping Modes Questionnaire.Results A total of 322 patients were included in the final analysis,yielding a valid response rate of 97.58％.The AOD score for young and middle-aged spinal cord injury patients was(25.99±6.68).Multiple linear regression analysis revealed that gender,education level,type of paralysis,injury duration,pain intensity,social support,psychological resilience,disease perception,and coping styles(confrontation and submission)were influencing factors of AOD(P＜0.05).Conclusion AOD among young and middle-aged spinal cord injury patients is at a moderate level.Healthcare professionals should pay particular attention to male patients,those with low literacy,quadriplegia,shorter injury durations,high pain intensity,low social support,weak psychological resilience,strong disease perception,and yielding coping styles.Timely interventions are recommended to enhance AOD,strengthen rehabilitation outcomes,and improve prognosis.

Taxifolin (TAX) is a natural compound known for its liver protection effect, but the mechanism remains unknown. Phosphorylated proteomics analyses discovered that the phosphorylation level of NDRG1 at T328 was a key event of TAX-improved liver fibrosis. We established models with NDRG1 knockout (KO) in vivo and in vitro, demonstrating that NDRG1 KO attenuated the development of hepatocyte injury, and combining NDRG1 KO and TAX administration did not result in a reduction in protection against liver injury. Cellular thermal shift assay and surface plasma resonance analysis showed that TAX directly binds to NDRG1 rather than its upstream kinase, subsequently demonstrating that TAX regulated phosphorylation of NDRG1 at T328 through binding to its C289 site. NDRG1 T328A (phosphorylated mutation) and T328E (mimic phosphorylation) in vivo and in vitro confirmed that pNDRG1_T328 exacerbates hepatocyte injury along with DNA damage, inflammatory response, and apoptosis, thereby contributing to hepatic stellate cells (HSCs) activation. In contrast, TAX can inhibit the above pathological abnormalities and block hepatocyte injury-triggered HSCs activation and fibrosis. Overall, TAX is a potent liver protection drug primarily targeting NDRG1 and inhibiting pNDRG1_T328 in hepatocytes.

Astragali Radix (AR), a traditional Chinese medicine (TCM), has demonstrated therapeutic efficacy against various diseases, including cardiovascular conditions, over centuries of use. While doxorubicin serves as an effective chemotherapeutic agent against multiple cancers, its clinical application remains constrained by significant cardiotoxicity. Research has indicated that AR exhibits protective properties against doxorubicin-induced cardiomyopathy (DIC); however, the specific bioactive components and underlying mechanisms responsible for this therapeutic effect remain incompletely understood. This investigation seeks to identify the protective bioactive components in AR against DIC and elucidate their mechanisms of action. Through network medicine analysis, astragaloside IV (AsIV) and formononetin (FMT) were identified as potential cardioprotective agents from 129 AR components. In vitro experiments using H9c2 rat cardiomyocytes revealed that the AsIV-FMT combination (AFC) effectively reduced doxorubicin-induced cell death in a dose-dependent manner, with optimal efficacy at a 1∶2 ratio. In vivo, AFC enhanced survival rates and improved cardiac function in both acute and chronic DIC mouse models. Additionally, AFC demonstrated cardiac protection while maintaining doxorubicin's anti-cancer efficacy in a breast cancer mouse model. Lipidomic and metabolomics analyses revealed that AFC normalized doxorubicin-induced lipid profile alterations, particularly by reducing fatty acid accumulation. Gene knockdown studies and inhibitor experiments in H9c2 cells demonstrated that AsIV and FMT upregulated peroxisome proliferator activated receptor γ coactivator 1α (PGC-1α) and PPARα, respectively, two key proteins involved in fatty acid metabolism. This research establishes AFC as a promising therapeutic approach for DIC, highlighting the significance of multi-target therapies derived from natural herbals in contemporary medicine.

Asthma is one of the most common diseases in chronic respiratory system;the etiology is complex,in-volving many types of inflammatory cells and a variety of signaling molecular mediators.Hydrogen sulfide(H2 S)is an endogenous gas transmitter in mammals,which is widely involved in cell functions and physiological and pathological processes of various diseases,including respiratory diseases.H2 S is involved in the occurrence and development of asthma through various ways.When the H2 S-producing enzyme level decreases,the concentration of endogenous H2 S level may trigger asthma attack and play a pro-inflammatory role.On the other hand,H2 S ini-tiates pulmonary inducible nitric oxide synthase(iNOS)activation,limiting airway remodeling,and acts as an anti-remodeling and anti-inflammatory mediator.Moreover,H2 S level varies at different stages of asthma.H2 S level in patients with asthma is a potential bio-markers of airway inflammation in asthma case and my support clin-ical diagnosis of asthma.

Purpose To explore the clinicopathological features and endoscopic manifestations of cap polyposis(CP).Methods Clinical,endoscopic,pathological,and follow-up data of 17 cases of CP were collected and ana-lyzed.Results There were 14 males and 3 females,aged 15-67 years,with a mean age of 36.5 years.The disease duration ranged from 2 weeks to 5 years,and most patients(64.7％,11/17)had symptoms for more than l year.The most common clinical manifestation was hematochezia(82.4％,14/17),while constipation was generally absent.En-doscopically,all lesions(100％,17/17)were located in the anal canal and lower rectum.The surface was invariably covered with a thick whitish exudate(100％,17/17),and annular growth was the most frequent pattern(76.5％,13/17).Pathologically,the mucosal layer was almost entirely replaced by granulation tissue,and the surface showed extensive inflammatory necrosis forming a cap-like structure.Conclusion CP predominantly occurrs in the anal canal and lower rectum of young men.The presence of abundant whitish exudate under endoscopy is differential diagnostic value.Complete endoscopic resection followed by pathological examination is required for definitive diagnosis.

Objective:To determine the epidemiological characteristics of human bocavirus (HBoV) in children with acute respiratory infections (ARI) in Bengbu City, Anhui Province, in 2024.Methods:Nasopharyngeal swab samples were collected from 269 children with ARI in Bengbu City, Anhui Province, in 2024. Seventeen respiratory pathogens were screened using quantitative fluorescence PCR. For HBoV-positive samples, the VP1/VP2 structural gene fragments of HBoV were amplified and sequenced for genetic evolutionary analysis.Results:Among the 269 nasopharyngeal swab samples from children with ARI, the overall detection rate of respiratory pathogens was 48.33% (103/269). The top three pathogens with the highest detection rates were: Influenza A virus (FluA): 10.04% (27/269), Respiratory syncytial virus (RSV): 8.18% (22/269), Human bocavirus (HBoV): 7.43% (20/269). The age distribution of HBoV-infected children showed that the detection rate was highest in the 0-2 years age group (50%, 10/20), followed by the 3-5 years age group (25%, 5/20) and the over 6 years age group (25%, 5/20). However, there was no statistically significant difference in viral detection rates among the age groups. Genetic evolutionary analysis based on VP1/VP2 revealed that all 13 HBoV strains were of the HBoV-1 genotype.Conclusions:HBoV is one of the major pathogens causing ARI in children in Bengbu City, Anhui Province, in 2024, with HBoV-1 being the predominant genotype. Additionally, infants aged 0-2 years are the most susceptible population to HBoV infection.

Autoimmune hepatitis （AIH） is an autoimmune disease characterized by liver parenchymal destruction and chronic fibrosis， and it is often mediated by T cells. The pathogenesis of AIH involves multiple factors， including sex， region， environmental factors， and genetic susceptibility. A notable predisposition is observed in female individuals， and the incidence rate of AIH in female individuals is significantly higher than that in male individuals. This sex difference is associated with various factors， and sex hormones may be an important cause of the female predominance of AIH， although the specific mechanisms remain unclear. An in-depth understanding of the mechanism of action of sex hormones in the pathogenesis of AIH will help to better understand the pathogenesis of the disease and may provide important clues for developing future treatment methods and prevention strategies. This article reviews the mechanism of action of estrogen and androgen in regulating the pathogenesis of AIH by regulating T cells， in order to provide new ideas and directions for further exploring the potential role of sex hormones in the etiology of autoimmune diseases.

Objective To explore the potential impact of unhealthy diets on cardiovascular diseases and all-cause mortality.Methods This study included the individuals aged 35-70 years from 45 cities and 70 rural communities across 12 provinces in China,as part of the Prospective Urban Rural Epidemiology(PURE)study.Dietary habits were assessed using a food frequency questionnaire.The dietary health status was scored using the Alternative Healthy Eating Index(AHEI),with participants in the lowest tertile of AHEI being categorized into the unhealthy diet group,while others were classified as the healthy diet group.The primary endpoints included major cardiovas-cular diseases(myocardial infarction,stroke,or heart failure)and all-cause mortality.Cox proportional hazard models were used to estimate hazard ratios(HR)for each group.Results A total of 40 925 participants were in-cluded in the study,with a median follow-up time of 11.9 years(interquartile range 9.6-12.6 years).During this period,2 066 deaths and 3 099 cases of major cardiovascular diseases were reported.The results showed that un-healthy diet increased the risk of major cardiovascular diseases by 10%(HR=1.10,95%CI:1.02-1.20,P＜0.05)and all-cause mortality by 7%(HR=1.07,95%CI:1.00-1.18,P＜0.05).Among male residents,un-healthy diet did not increase the risk of major cardiovascular diseases or all-cause mortality.However,among female residents,those with an unhealthy diet had a higher risk of major cardiovascular diseases(HR=1.12,95%CI:1.00-1.25,P＜0.05)and all-cause mortality(HR=1.26,95%CI:1.08-1.46,P＜0.05)compared to those with a healthy diet.Conclusions Unhealthy diet increases the risk of major cardiovascular diseases and all-cause mortality,particularly among women.There is a need to raise awareness about healthy dietary to prevent death and the occurrence of major cardiovascular diseases.
