ObjectiveChinese patent medicines for cardiovascular and cerebrovascular diseases are diverse and complex in their efficacy. The traditional classification method based on efficacy categories has certain limitations and cannot meet the clinical needs for individualized drug selection and variety comparison. This article， based on the formulation compatibility analysis technology of "Tangye Jingfa Tu"， clarifies the composition and efficacy characteristics of common Chinese patent medicines used for cardiovascular and cerebrovascular diseases， providing support for the precise selection of these medicines. MethodsFifty-six representative Chinese patent medicines， covering all the efficacy subcategories of "stasis-resolving agents" in the National Basic Medical Insurance， Work Injury Insurance， and Maternity Insurance Drug Catalogue （2023） （more than 50% of the total）， were selected for the study. Within the knowledge system of "Tangye Jingfa Tu"， the compatibility structure of herbal flavors and the proportion structure of herbal quantities for each Chinese patent medicine were determined. The correlation between these structures and the efficacy categories was analyzed to identify the similarities and differences among the selected Chinese patent medicines. Additionally， the efficacy was reclassified and compared according to the theoretical framework of tonifying and purging methods of five Zang organs in the "Tangye Jingfa Tu". ResultsThe representative Chinese patent medicines included in the analysis were Shexiang Baoxin pills， Danshen tablets， Qili Qiangxin capsules， Breviscapine tablets， etc.， covering all the efficacy subcategories of "stasis-resolving agents". Among the 56 representative Chinese patent medicines， salty flavor was the most common （48）， followed by pungent （33）， and sweet （26）. According to the dominant herbal flavor， salty flavor was the most common （37）， followed by pungent （9）， and sour （5）. According to the dominant herbal quantity， salty flavor was the most common （27）， followed by sour （7）， and pungent （5）. Furthermore， Chinese patent medicines with different efficacy subtypes showed different flavor characteristics. For example， most Qi-invigorating and blood-activating agents contained sweet drugs for tonifying the spleen （9/10）， most Qi-moving and blood-activating agents contained pungent drugs for tonifying the liver （7/8）， and all kidney-invigorating and blood-activating agents contained bitter drugs for tonifying the kidneys （6/6）. However， the efficacy classification of individual medicines did not always align with the compatibility characteristics of their formulas， as seen with Dengyin Naotong capsules. ConclusionThe formulations of Chinese patent medicines for cardiovascular and cerebrovascular diseases predominantly feature salty， sour， and pungent flavors， which largely conform to the therapeutic principles of "nourishing the heart with salt and soothing the heart with sour" and the liver-heart， heart-spleen mother-child treatment relationship shown in the "Tangye Jingfa Tu". Using the "Tangye Jingfa Tu" framework to conduct research on the structure and efficacy characteristics of Chinese patent medicines is objective and effective.

Objective:To investigate the expression of EIF3B and its role in the development of laryngeal carcinoma. Methods:Immunohistochemistry, cell culture, cell transfection, qRT-PCR, Western Blot and other techniques were used to determine the expression difference of EIF3B in laryngeal cancer and adjacent tissues, and analyze the relationship between EIF3B and the size and TNM stage of laryngeal cancer. By constructing a laryngeal carcinoma cell model with EIF3B knocked down, the cell function was studied, and the regulatory effect of EIF3B on laryngeal carcinoma cells was proved in vitro. Finally, the effect of EIF3B on laryngeal carcinoma growth in vivo was studied by subcutaneous xenograft tumor model in nude mice. Results:The signal intensity of EIF3B in laryngeal carcinoma tissues was significantly stronger than that in adjacent tissues, and the expression level of EIF3B was positively correlated with patient age, TNM stage, lymph node metastasis, tumor size and clinical stage. Knocking down EIF3B can significantly inhibit the proliferation, migration and aggregation of cancer cells, and promote apoptosis. In vivo experiments with nude mice also showed that down-regulating EIF3B expression could inhibit tumor formation in vivo. Conclusion:The expression of EIF3B in laryngeal cancer is significantly increased, and it is closely related to the pathological characteristics of laryngeal cancer, which can be used as a diagnostic index of laryngeal cancer. In terms of function, EIF3B knockdown can inhibit the proliferation, migration and tumor formation of laryngeal cancer cells in vitro and in vivo, and may become a candidate target for targeted therapy of laryngeal cancer in the future.

Rheumatoid arthritis （RA） is an autoimmune disease involving symmetrical small joints， with clinical manifestations such as small joint swelling， morning stiffness， progressive pain， and even joint deformity and loss of function. Due to the complex immune mechanism， the pathogenesis of RA remains unclear. However， studies have shown that the pathogenesis of RA is related to abnormal immune mechanism， increased synovial inflammatory response， abnormal biological behavior of RA fibroblast-like synoviocytes （RA-FLSs）， and abnormal degradation of extracellular matrix. Mitogen-activated protein kinase （MAPK） plays a key role in the regulation of cell growth， proliferation， differentiation， and apoptosis. It is involved in the abnormal release and activation of inflammatory mediators in RA， the abnormal proliferation， migration， and invasion of RA-FLSs， synovial angiogenesis， bone erosion， and cartilage destruction. The thousands of years of practical experience show that Chinese medicine can effectively mitigate the clinical symptoms such as joint swelling， morning stiffness， and pain and delay the occurrence of joint deformity in RA patients. Moreover， the Chinese medicine treatment has the advantages of overall regulation， personalized treatment， multiple pathways and targets， high safety， few adverse reactions， and stable quality. Modern studies have confirmed that Chinese medicine can play a role in the prevention and treatment of RA by interfering in the MAPK signaling pathway， reducing pro-inflammatory cytokines， inhibiting the abnormal proliferation， migration， and invasion of RA-FLSs， regulating the apoptosis of RA-FLSs， and protecting extracellular matrix. This article elaborates on the key role of MAPK signaling pathway in the development of RA and reviews the latest research results of Chinese medicine intervention in MAPK signaling pathway for the prevention and treatment RA， aiming to provide a basis for the development of new drugs and the clinical application of Chinese medicine in the prevention and treatment of RA.

By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

OBJECTIVE To explore the potential mechanism of the effect of Xuebijing injection （XBJ） on neurological function and survival of rats after cardiac arrest （CA）/cardiopulmonary resuscitation （CPR） based on the S-nitrosoglutathione reductase （GSNOR）/S-nitrosoglutathione （GSNO） pathway. METHODS The CA/CPR rat model was established by ventricular fibrillation. Using a sham operation group as control， high-throughput sequencing was employed to analyze and mine the differentially expressed genes （DEGs）. Enzyme-linked immunosorbent assay was used to determine the contents of GSNOR and GSNO in the hippocampus； the active components of XBJ were screened and subjected to molecular docking analysis with GSNOR. The rats successfully modeled using the same method were divided into model group （n＝30）， inhibitor （GSNOR inhibitor） group （n＝30）， XBJ group （n＝30） and XBJ+inhibitor group （n＝30）， and a sham operation group （n＝30） was set up. Neurological function was evaluated and survival status was recorded at 3 hours， 24 hours and 3 days after the first 89） drug intervention. The contents of GSNOR and GSNO in the hippocampus of rats were determined in each group at the 0191） above time points， and the relationship of the contents of GSNOR and GSNO with modified neurologic severity scale （mNSS） score was analyzed. RESULTS GSNOR coding gene was differentially expressed between the model group and the sham operation group. Compared with the sham operation group， GSNOR content increased significantly in the hippocampus of rats in model group， while GSNO content decreased significantly （P＜0.05）. The active components of XBJ， such as 4- methylenemiltirone and salviolone， could be bound to GSNOR protein， with the binding energy lower than －6 kcal/mol， mainly connected by hydrogen bonds. Animal experiments revealed that mNSS score and GSNOR levels in the hippocampus of rats in the model group were significantly higher than those in the sham operation group （P＜0.05）， while GSNO levels and survival rate were significantly lower than those in the sham operation group （P＜0.05）. The above indexes of rats were improved significantly in administration groups， the mNSS score in the XBJ group was significantly lower than that in the inhibitor group， the content changes of GSNOR and GSNO in the inhibitor group were more obvious than those in the XBJ group， and the various indicators in the XBJ+inhibitor group were significantly better than the XBJ group and the inhibitor group （P＜0.05）. GSNOR content was positively correlated with the mNSS score， and GSNO content was negatively correlated with the mNSS score （P＜0.05）. CONCLUSIONS XBJ can improve the neurological function of rats and enhance their survival rates after CA/CPR， the mechanism of which may be associated with the down-regulation of GSNOR and the up-regulation of GSNO.
