Alzheimer's disease (AD) is one of the most common diseases in the elderly population. Its etiology involves multiple pathogenic factors and pathological links such as abnormal deposition of β amyloid protein (Aβ), hyperphosphorylation of Tau protein, abnormalities of the cholinergic system, oxidative stress, and inflammatory response. However, its specific pathogenesis has not been clarified, and no specific therapeutic drugs have been found. In recent years, more and more studies have paid attention to the potential of chemical components of traditional Chinese medicine (TCM) in the treatment of AD. However, the diversity and complexity of the chemical components of TCM may have a positive impact on multiple pathological links of AD. Researchers have isolated many active components from TCMs, and the effects of treating AD have been confirmed by modern pharmacological studies. Through literature analysis, this article found that the main chemical components of TCM with anti-AD effects were saponins (31%), flavonoids (24%), polysaccharides (20%), lactones (8%), alkaloids (7%), phenols (3%), and other compounds (7%). Among them, ginsenoside, notoginsenoside, epimedium flavones, puerarin, baicalein, schisandra polysaccharide, angelica polysaccharide, ganoderma lucidum polysaccharide, pachyman, huperzine A, berberine, andrographolide, curcumin, emodin, and gastrodin have been extensively studied in terms of their anti-AD effects, and their mechanisms of pharmacological action have been involved in many aspects of AD pathogenesis. This article reviews the anti-AD activities and possible mechanisms of chemical components of TCM, so as to provide a reference for the development of new drugs for the prevention and treatment of AD.

Programmed death protein 1 (PD-1) and programmed death protein ligand-1 (PD-L1) play pivotal roles in maintaining immune homeostasis and a crucial link in tumour immune evasion. PD-1/PD-L1 inhibitors have achieved significant efficacy in many cancer immunotherapy, but the effect in the treatment of pancreatic cancer is limited, and the effect of monotherapy is suboptimal. The combined therapeatic effect of PD-1/PD-L1 and chemotherapy, radiotherapy, and molecular targeted therapy were explored. This article summarises the advancements in PD-1/PD-L1 inhibitor combination therapy in the treatment of pancreatic cancer.

ObjectiveTo analyze the clinical application hotspots, development trends, compatibility characteristics, application rules, and formulation mechanisms of the Chinese marine drug pair Haliotidis Concha-Oystreae Concha in order to provide references for its clinical medication and further research. MethodBy means of various modern literature databases such as China National Knowledge Infrastructure (CNKI), modern clinical prescriptions containing Haliotidis Concha-Oystreae Concha, as well as the clinical application hotspots, were retrieved, followed by visualized analysis of hotspots and development trends of their clinical applications using Citespace. The drug composition, efficacy and indications, and drug dosages in the prescriptions were statistically analyzed. Additionally, various statistical software including SPSS Modeler 18.0 were employed to analyze the indications, syndromes, and formulation rules of Haliotidis Concha-Oystreae Concha. ResultThe visualized analysis included 90 articles, revealing a gradual decrease in publications in this field in recent years. Key clinical application keywords were identified as hypertension, collateral deficiency producing wind, insomnia, etc. Eighty clinical prescriptions were retrieved, involving 121 drugs. Frequency analysis of compatibility demonstrated that the top 10 drugs were Uncariae Ramulus cum Uncis, Gastrodiae Rhizoma, Os Draconis, Achyranthis Bidentatae Radix, Paeoniae Radix Alba, Chrysanthemi Flos, Scutellariae Radix, Gardeniae Frucuts, Glycyrrhizae Radix et Rhizoma, and Polygoni Multiflori Caulis. Association rule analysis showed that core combinations included "Uncariae Ramulus cum Uncis-Achyranthis Bidentatae Radix" and "Os Draconis-Pheretima-Chuanxiong Rhizoma". Through factor reliability analysis, new drug combinations were derived, such as "Gastrodiae Rhizoma-Polygoni Multiflori Caulis-Eucommiae Cortex-Taxilli Herba-Leonuri Herba", "Achyranthis Bidentatae Radix-Uncariae Ramulus cum Uncis", "Scutellariae Radix-Glycyrrhizae Radix et Rhizoma-Margarita-Prunellae Spica", "Os Draconis-Pheretima-Bombyx Batryticatus", "Chrysanthemi Flos-Chuanxiong Rhizoma", "Poria-Acori Tatarinowii Rhizoma", and "Paeoniae Radix Alba-Gardeniae Fructus-Sclerotium Poriae Pararadicis". The Haliotidis Concha-Oystreae Concha drug pair was mainly used to treat diseases with liver Yang hyperactivity syndrome, with hypertension accounting for 40.00%, migraines for 30.00%, and dizziness for 15.00%. In the treatment of liver Yang hyperactivity syndrome, the main categories of compatible drugs were liver-pacifying and wind-extinguishing ones (19.86%), blood-activating and stasis-resolving ones (12.13%), and spirit-calming ones (10.08%). High-frequency drugs in the prescriptions function to reduce blood pressure through multiple pathways, such as increasing nitric oxide (NO) levels, downregulating angiotensin Ⅱ (Ang Ⅱ), and inhibiting angiotensin-converting enzyme (ACE). ConclusionThrough comprehensive analysis of the results, the Haliotidis Concha-Oystreae Concha drug pair is commonly used for hypertension with liver Yang hyperactivity syndrome, and is often combined with deficiency-tonifying, liver-pacifying and wind-extinguishing, heat-clearing, and spirit-calming drugs, aiming to simultaneously extinguish wind, relieve spasms, and pacify the liver to subdue Yang, while also clearing heat to relax bowels, stabilizing the mind, and enhancing the liver-pacifying and Yang-subduing effects of this drug pair.

Objective:To analyze the correlation between nasal resistance and lung function in children with allergic rhinitis(AR), and explore whether AR children with increased nasal resistance are accompanied by potential lower respiratory tract involvement. Methods:A total of 88 children diagnosed with AR from December 2021 to December 2022 were selected as the study group, while 20 normal children were selected as the control group during the same period. Both the study group and the control group children underwent lung function tests, bronchodilator tests, and nasal resistance measurements. Spearman correlation analysis and multiple linear regression analysis were performed on the results of nasal resistance and lung function tests to explore the relationship and influencing factors between the two groups.According to the results of nasal resistance measurement, children with increased nasal resistance and abnormal lung function were divided into a mild increase in nasal resistance with abnormal lung function group and a moderate to severe increase in nasal resistance with abnormal lung function group. The degree of increased nasal resistance was analyzed to determine whether it would affect lung function. Results:The FEF25, FEF50, and FEF75 levels in the study group were significantly lower than those in the control group(P<0.05). The FEV1of children with moderate to severe increase in AR nasal resistance was significantly lower than that of children with mild increase in AR nasal resistance(P<0.05). There was a correlation between nasal resistance and FEV1/FVC, R20 in AR children, and FEV1/FVC, R20 were the influencing factors of nasal resistance in AR children(P<0.05). There was no correlation between total serum IgE, lung function, and bronchodilation test in AR patients(P>0.05). Conclusion:The nasal ventilation function of AR patients has changed, and there is a downward trend in small airway function. Children with moderate to severe increase in AR nasal resistance have a more significant decrease in lung ventilation function than those with mild increase. The nasal resistance of AR children is influenced by FEV1/FVC and R20, and FEV1/FVC and R20 decrease as the nasal resistance value increases. The improvement rate of lung function and FEV1 are not influencing factors for the elevation of total serum IgE.

Glycyrrizae Radix et Rhizoma has high medicinal value and is widely used in compatibility. It is used most frequently in the compatibility of Chinese medicine prescriptions,and is known as ''Guolao''(national medicine) and "master of all medicines". The characteristic active ingredients are mainly liquitin,glycyrrizic acid,glycyrrizin,and licochalcone. In different compatibilities,based on traditional and modern pharmacological theories,the corresponding effect of Glycyrrizae Radix et Rhizoma are brought into play through different mechanisms. Based on the traditional pharmacology of Glycyrrizae Radix et Rhizoma for tonifying spleen,replenishing Qi,clearing heat,removing toxin,dispelling phlegm,relieving cough and pain,and harmonizing various medicines,this paper used herbal authentication to analyze its compatibility application and mechanism. It was found that Glycyrrizae Radix et Rhizoma played corresponding effect in compatibilities through "tonification","harmonization",and "regulation". For example,Glycyrrizae Radix et Rhizoma was combined with tonics including Ginseng Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma to tonify the five Zang-organs through its strong tonifying effect,combined with Paeoniae Radix Alba and Aconiti Lateralis Radix Praeparata to relieve emergencies and pains through harmonizing medicine power and properties,and combined with Rhei Radix et Rhizoma and Natrii Sulfas to reduce medicine intensity through regulating medicine properties and body characteristics. The application law and mechanism of the modern pharmacological compatibility of Glycyrrizae Radix et Rhizoma were analyzed by data mining and network pharmacology. It was found that the modern clinical formula was often compatible with Glycyrrizae Radix et Rhizoma for anti-inflammation,cardiovascular and cerebrovascular protection,anti-virus,and anti-tumor,Ephedrae Herba and Scutellariae Radix for anti-inflammation,Bambusae Caulis in Taenias,Salviae Miltiorrhizae Radix et Rhizoma,and Aurantii Fructus Immaturus for cardiovascular and cerebrovascular protection,and Ophiopogonis Radix and Chuanxiong Rhizoma for nerves protection. Meanwhile,the important targets of the characteristic ingredients were protein kinase B1 (Akt1),interleukin-6 (IL-6),tumor necrosis factor (TNF),and epidermal growth factor receptor (EGFR). The important characteristic pathways such as tyrosine kinase inhibitor resistance pathway and cyclic guanosine monophosphate (cGMP)/protein kinase G (PKG) signal pathway played the role of cardiovascular and cerebrovascular protection,and proteoglycan pathway in cancer played a neuroprotective role. This study is expected to provide references for the rational compatibility and application of Glycyrrizae Radix et Rhizoma,as well as the compatibility application of Chinese medicine prescriptions.

【Objective】 To evaluate the association between prophylactic plasma transfusion and postoperative bleeding rate in critically ill patients undergoing different invasive procedures. 【Methods】 The information of ICU patients who received different invasive procedures from January 2019 to December 2019 in 6 tertiary hospitals in China were retrospectively investigated. The inclusion criteria of patients were as follows: age ≥ 18 years; received invasive procedures; INR ≥ 1.5 within 72 hours before surgery. Exclusion criteria were patients with incomplete case records. The patients finally included in the study were divided into prophylactic plasma transfusion group and non-prophylactic plasma transfusion group according to their plasma transfusion status. The outcome variable was the incidence of invasive procedure-related bleeding within 48 hours after different invasive procedures. 【Results】 A total of 407 patients underwent invasive procedures, and 362 patients were finally included in this study after excluding 45 patients with incomplete case records. The proportions of prophylactic plasma transfusion in different types of invasive procedures were central venous catheterization (46/146, 31.5%), thoracentesis (13/37, 35.1%), bronchoscopy (8/31, 25.8%), tracheal intubation (9/38, 23.7%), arterial catheterization (9/50, 18.0%) and others (13/60, 21.7%). The bleeding rates showed that different invasive procedures presented no statistical difference between the groups received plasma transfusion or not. In the prophylactic plasma transfusion group, the bleeding rate of arterial catheterization (4/9, 44.4%) was the highest, but all were potential bleeding, followed by tracheal intubation (4/10, 40.0%) and central venous intubation (16/46, 34.8%), with a higher rate of significant bleeding. 【Conclusion】 Prophylactic infusion of plasma did not reduce the bleeding rate after different invasive procedures, but prospective studies are needed to further confirm the conclusion; this study also provides a certain data basis for later prospective studies.

Zedoary tumeric (Curcumae Rhizoma, Ezhu in Chinese) has a long history of application and has great potential in the treatment of liver cancer. The antiliver cancer effect of zedoary tumeric depends on the combined action of multiple pharmacodynamic substances. In order to clarify the specific mechanism of zedoary tumeric against liver cancer, this paper first analyzes the mechanism of its single pharmacodynamic substance against liver cancer, and then verifies the joint anti liver cancer mechanism of its “pharmacodynamic group”. By searching the research on the antihepatoma effect of active components of zedoary tumeric in recent years, we found that pharmacodynamic substances, including curcumol, zedoarondiol, curcumenol, curzerenone, curdione, curcumin, germacrone, β-elemene, can act on multi-target and multi-channel to play an antihepatoma role. For example, curcumin can regulate miR, GLO1, CD133, VEGF, YAP, LIN28B, GPR81, HCAR-1, P53 and PI3K/Akt/mTOR, HSP70/TLR4 and NF-κB. Wnt/TGF/EMT, Nrf2/Keap1, JAK/STAT and other pathways play an antihepatoma role. Network pharmacological analysis showed that the core targets of the “pharmacodynamic group” for anti-life cancer are AKT1, EGFR, MAPK8, etc, and the core pathways are neuroactive live receiver interaction, nitrogen metabolism, HIF-1 signaling pathway, etc. At the same time, by comparing and analyzing the relationship between the specific mechanisms of pharmacodynamic substance and “pharmacodynamic group”, it is found that they have great reference significance in target, pathway, biological function, determination of core pharmacodynamic components, formation of core target protein interaction, in-depth research of single pharmacodynamic substance, increasing curative effect and so on. By analyzing the internal mechanism of zedoary tumeric pharmacodynamic substance and “pharmacodynamic group” in the treatment of liver cancer, this paper intends to provide some ideas and references for the deeper pharmacological research of zedoary tumeric and the relationship between pharmacodynamic substance and “pharmacodynamic group”.

Stromal vascular fraction(SVF)are the remaining cells after removing mature fat cells in the adipose tissue. Containing a certain amount of adipose derived stem cells(ADSCs), SVF also includes many other cells, which may have the potential of promoting angiogenesis. In this review, the role of SVF in angiogenesis after fat transplantation was summarized by intensive reading relative literature in recent years. The result is that angiogenesis and fat graft revascularization are regulated by various factors: SVF promotes secretion of a diverse array of cytokines and growth which are capable of stabilizing endothelium vascular network. ADSCs have the potential of differentiating into smooth muscle cells and endothelial cells which can coroperate to form new blood vessels.
