ObjectiveTo explore the mechanism of Shenmai injection in improving cisplatin resistance in non-small cell lung cancer （NSCLC） based on the endoplasmic reticulum stress through protein kinase R-like endoplasmic reticulum kinase （PERK）/activated transcription factor 4 （ATF4）/C/EBP homologous protein （CHOP） signaling pathway. MethodsBALB/c nude mice bearing cisplatin-resistant human lung cancer cell line （A549/cisplatin） were randomly divided into four groups： Blank control group （0.9% sodium chloride）， cisplatin group （5 µg·g^-1cisplatin）， Shenmai injection group （5.2 mg·g^-1 Shenmai injection）， and combination therapy group （5.2 mg·g^-1 Shenmai injection +5 µg·g^-1cisplatin）. The drug intervention lasted for 4 weeks， and the changes in body weight and tumor volume were monitored. Hematoxylin-eosin （HE） staining was performed to observe tumor tissue pathology. Transmission electron microscopy （TEM） was used to assess the morphology of the endoplasmic reticulum. Immunohistochemical assay was conducted to measure the positive expressions of PERK， ATF4， and CHOP in tumor tissues. Western blot quantified the protein expression of immunoglobulin heavy chain binding protein （BIP）， PERK， phosphorylated PERK （p-PERK）， eukaryotic translation initiation factor 2α （eIF2α）， phosphorylated eIF2α （p-eIF2α）， ATF4， CHOP， B-cell lymphoma -2 （Bcl-2）， and Bcl-2 Associated X protein （Bax）. A549/cis cells were divided into blank group： Blank control group （normal culture medium）， cisplatin group （23.3 µmol·L^-1 cisplatin）， Shenmai Injection group （20 g·L^-1 Shenmai injection）， and combination therapy group （20 g·L^-1 Shenmai injection+23.3 µmol·L^-1 cisplatin）. Cell counting kit-8 （CCK-8） method was used to detect cell viability， TEM was used to observe the morphology of endoplasmic reticulum， and Western blot was used to detect endoplasmic reticulum stress and apoptosis-related proteins. ResultsCompared with the cisplatin group， the combination therapy group showed increased body weight （P<0.05）， decreased tumor volume （P<0.05）， and expanded endoplasmic reticulum in tumor cells. The positive expressions of PERK， ATF4， and CHOP increased （P<0.05）. Western blot revealed elevated protein expression levels of BIP， p-PERK/PERK， p-eIF2α/eIF2α， ATF4， CHOP， and Bax （P<0.05）， while Bcl-2 expression decreased （P<0.05）. As shown in the in vitro experiment， compared with the cisplatin group， the combination therapy group exhibited a reduced cell survival rate （P<0.05）. TEM revealed increased endoplasmic reticulum dilation and vesicular degeneration. Western blotting showed increased protein levels of BIP， p-PERK/PERK， p-eIF2α/eIF2α， ATF4， CHOP and Bax （P<0.05）， with decreased Bcl-2 expression （P<0.05）. ConclusionShenmai injection combined with cisplatin has a synergistic antitumor effect in NSCLC， which may be attributed to the activation of endoplasmic reticulum stress response mediated by the PERK/eIF2α/ATF4/CHOP signaling pathway and the induction of tumor cell apoptosis.

Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

Natural flavonoids have attracted considerable attention owing to their favorable biosafety profiles and multiple pharmacological properties in recent years. Luteolin, a representative flavonoid compound, exhibits anti-inflammatory, antioxidant, anti-angiogenic, and neuroprotective effects in multiple ocular disease models by modulating key signaling pathways, including NF-κB, PI3K/Akt, Nrf2/HO-1, and AGE-RAGE. Accumulating experimental evidence supports the potential application of luteolin in various ocular diseases, including corneal and ocular surface diseases, inflammatory eye diseases, glaucoma, cataract, diabetic retinopathy, and age-related macular degeneration. However, clinical evidence remains limited. This review systematically summarizes research progress on luteolin in ocular diseases over the past five years, analyzes its molecular mechanisms and therapeutic potential, and discusses future directions,so as toprovide a theoretical basis for clinical translation.

Chronic heart failure （CHF） is the final stage of cardiovascular diseases. It is a complex syndrome， with dyspnea and edema as the main clinical manifestations， and it is characterized by complex disease conditions， difficult cure， and high mortality. Ferroptosis， a new type of programmed cell death， is different from other types of programmed cell death. Ferroptosis is iron-dependent， accompanied by lipid peroxide accumulation and mitochondrial shrinkage， becoming a hot research topic. Studies have confirmed that ferroptosis plays a key role in the occurrence and development of CHF. The regulation of ferroptosis may become a potential target for the treatment of CHF in the future. The theory of Qi deficiency and stagnation refers to the pathological state of original Qi deficiency and abnormal transportation and distribution of Qi， blood， and body fluid， which has guiding significance for revealing the pathogenesis evolution of some chronic diseases. We believe that Qi deficiency and stagnation is a summary of the pathogenesis of ferroptosis in CHF. Deficiency of Qi （heart Qi） is the root cause of CHF， and stagnation （phlegm turbidity and blood stasis） is the branch of this disease. The two influence each other in a vicious circle to promote the development of this disease. Traditional Chinese medicine （TCM） plays an important role in the treatment of CHF， improving the prognosis and quality of life of CHF patients. This paper explores the correlation between the theory of Qi deficiency and stagnation and the mechanism of ferroptosis in CHF. Furthermore， this paper reviews the mechanism of Chinese medicines and compound prescriptions in preventing and treating CHF by regulating ferroptosis according to the principles of replenishing Qi and dredging to remove stagnation， aiming to provide new ideas and methods for the treatment of CHF with TCM.

Objective To observe the therapeutic efficacy of Jisheng Shenqi Pills combined with endocrine therapy in alleviating lower urinary tract obstruction symptoms of patients with advanced prostatecancer(PCa).Methods A total of 68 patients with advanced PCa complicated by lower uri-nary tract obstruction symptoms were randomly divided into observation group and control group,with 34 cases in each group.The control group received endocrine therapy alone,while the observation group received Jisheng Shenqi Pills on the basis of the control group.Both groups underwent a course of 3-month treatment.The total therapeutic effectiveness rate,traditional Chinese medicine(TCM)syndrome scores,maximum urinary flow rate(Qmax),residual urinary volume(RUV),International Prostate Symptom Score(IPSS),prostate-specific antigen(PSA)levels,and Quality of Life(QOL)Scale scores were compared between the two groups.Results The total therapeutic effectiveness rate in the observation group was 94.12％,which was significantly higher than 82.35％in the control group(P＜0.05).After treatment,TCM syndrome scores decreased in both groups,with the obser-vation group had significantly lower scores than the control group(P＜0.05).Both groups exhibited an increase in Qmax and a decrease in RUV after treatment,with the observation group had significant-ly higher Qmax and lower RUV compared to the control group(P＜0.05).PSA level decreased signif-icantly in both groups after treatment(P＜0.05),but no significant difference was observed between the two groups(P＞0.05).IPSS score was decreased while QOL score was increased in both groups after treatment,with the observation group had significantly lower IPSS score and higher QOL score compared to the control group(P＜0.05).Conclusion Jisheng Shenqi Pills combined with endo-crine therapy effectively alleviates urinary obstruction symptoms,improves TCM syndromes,and en-hances quality of life in patients with advanced PCa.

Heart failure is a group of complex clinical syndromes that represent the final stage of cardiovascular disease development， characterized by an extremely high mortality rate. However， due to the complexity of the pathological mechanisms， an effective treatment method has not yet been found. Mitochondria are among the most critical organelles in cells， playing an essential role in energy supply and widely participating in various life activities， such as the regulation of oxidative stress and apoptosis. The normal functioning of mitochondria is crucial for maintaining the body's normal life activities. In recent years， studies have found that mitochondrial dysfunction is associated with the occurrence and progression of various diseases， particularly closely related to the onset of heart failure. An imbalance in mitochondrial homeostasis is a key factor in cardiomyocyte death and the onset of heart failure. Mitochondrial autophagy， as a means of regulating mitochondrial homeostasis， is significant for the prevention and treatment of heart failure. Traditional Chinese medicine （TCM） therapy is a unique treatment approach in China now widely applied in clinical practice， demonstrating significant efficacy in treating heart failure， with unique advantages. Modern pharmacological research indicates that Chinese medicine monomers and compounds can target and regulate mitochondrial homeostasis in cardiomyocytes， affect mitochondrial autophagy， and protect cardiomyocytes， though the specific mechanisms remain unclear. Therefore， this paper explored the mechanisms of the PTEN-induced putative kinase 1 （PINK1）/Parkin pathway in mitochondrial autophagy and heart failure， reviewed the effects of PINK1/Parkin-mediated mitochondrial autophagy on heart failure， and discussed the therapeutic effects of PINK1/Parkin-mediated mitochondrial autophagy on heart failure in conjunction with TCM. This paper is expected to provide new ideas and methods for the prevention and treatment of heart failure from the perspective of PINK1/Parkin regulation of mitochondrial autophagy.

OBJECTIVE To investigate the effect of bs-5-YHEDA iron chelating peptide combined with semaglutide on the cognitive ability and pathological characteristics of D-Gal-induced Alzheimer's disease(AD) model mice. METHODS Forty mice were randomly divided into 5 groups, namely the healthy control group, PBS group, bs-5-YHEDA iron chelating peptide group, combined treatment group and positive control group, with 8 mice in each group, half of each sex. Except for the healthy control group, D-galactose was injected to induce the AD mice model for 6 weeks. For 3 consecutive weeks starting from the 4th week, the bs-5-YHEDA iron chelating peptide group was injected with bs-5-YHEDA(1 mg·mL–1) once every other day at 200 µL in the tail vein; the bs-5-YHEDA iron chelating peptide(1 mg·mL–1) and semaglutide(25 nmol·kg–1·d–1) were given alternately once a day in the combination treatment group; the positive control group was given memantine(3.3 mg·kg–1·d–1) by gavage every other day. The healthy control group and PBS group were injected with the equal dose of PBS. At the end of treatment, the learning memory ability of mice was detected by the Morris water maze method, whole brain and whole blood were dissected, and pathological changes in hippocampal region were observed by HE staining, and Aβ expression and Tau protein phosphorylation levels were detected by immunohistochemistry, enzyme-linked immunosorbent assay and immunoblotting. RESULTS In the Morris water maze spatial exploration experiment, the differences in the number of times the mice traversed the platform, the ratio of swimming distance to the target quadrant, and the time ratio were statistically significant in each group(P<0.05); compared with the PBS group, the ratio of swimming distance to the target quadrant increased in the combined treatment group, and the differences were statistically significant(P<0.05). The results of HE staining showed that compared with the healthy control mice, the hippocampal area in the PBS group showed reduced levels of pyramidal cells, disorganized arrangement, cell edema, and deep staining of nuclei consolidation. Cellular disorganization, deep staining of nuclei and apoptosis in the hippocampus were significantly improved in each treatment group after drug treatment. Immunohistochemistry and Western blotting results showed that the Aβ expression levels and Tau protein phosphorylation levels were significantly higher in the PBS-administered mice compared with the healthy control mice, and the Aβ expression levels and Tau protein phosphorylation levels were reduced in each group after drug treatment, with statistically significant differences(P<0.01 or P<0.001 ). CONCLUSION The combination of bs-5-YHEDA iron chelating peptide and semaglutide can effectively improve the learning and memory ability and pathological characteristics of AD mice, but from the results of immunohistochemistry and immunoblotting experiments, the improvement of pathological characteristics of AD mice in the combination treatment group is not obvious compared with the single bs-5-YHEDA iron chelating peptide group, suggesting that there may be a threshold effect of our designed dual-target combination treatment on the cognitive improvement of AD mice, and the optimization and validation of the effect of multi-target combination treatment need further study.

Objective To investigate the efficacy and safety of camrelizumab monoclonal antibody combined with molecular-targeted therapy in elderly patients with unresectable or advanced hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the patients with unresectable/advanced HCC who attended six hospitals from January 1,2019 to March 31,2021,and all patients received camrelizumab monoclonal antibody treatment,among whom 84.8%also received targeted therapy.According to the age of the patients,they were divided into elderly group(≥65 years)and non-elderly group(＜65 years).The two groups were assessed in terms of overall survival(OS),progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),and immune-related adverse events(irAE).The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups;the independent samples t-test was used for comparison of normally distributed continuous data,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups.The Kaplan-Meier method was used for survival analysis,and the log-rank test was used for comparison of survival curves.Univariate and multivariate Cox proportional hazards regression analyses were used to determine the independent influencing factors for PFS and DCR at 6 months.Results A total of 99 HCC patients were enrolled,with 27 in the elderly group and 72 in the non-elderly group.The elderly group had an OS rate of 67.8%,an ORR of 44.4%,and a DCR of 74.1%at 12 months and a median PFS of 6.4(95%confidence interval[CI]:3.0-12.4)months,with no significant differences compared with the non-elderly group(all P＞0.05).The median OS was unavailable for the elderly group,while the non-elderly group had an OS of 18.9(95%CI:13.0-24.8)months;there was no significant difference between the two groups(P=0.485).The univariate and multivariate Cox regression analyses showed that major vascular invasion(MVI)was an independent risk factor for PFS(hazard ratio[HR]=2.603,95%CI:1.136-5.964,P=0.024)and DCR(HR=3.963,95%CI:1.671-9.397,P=0.002)at 6 months,while age,sex,etiology of HBV infection,presence of extrahepatic metastasis,Child-Pugh class B,and alpha-fetoprotein＞400 ng/mL were not associated with PFS or DCR at 6 months.For the elderly group,the incidence rates of any irAE and grade 3/4 irAE were 51.9%and 25.9%,respectively,with no significant differences compared with the non-elderly group(P＞0.05),and skin disease was the most common irAE in both groups(39.4%).Conclusion Camrelizumab monoclonal antibody combined with molecular-targeted therapy has similar efficacy and safety in patients with unresectable/advanced HCC aged≥65 years and those aged＜65 years.MVI is associated with suboptimal response to immunotherapy and poor prognosis.
