AIM To compare the chemical constituents in traditional decoction and formula granule decoction of classical famous prescription Wendan Decoction.METHODS The HPLC fingerprints were established,after which the contents of adenosine,synephrine,liquiritin,naringin,hesperidin,6-gingerol and adenosine cyclophosphate were determined,cluster analysis,principal component analysis and multidimensional scaling analysis were adopted in the investigation of component differences,and the equivalent of formula granules was adjusted.RESULTS The similarities of HPLC fingerprints for 10 batches of traditional decoctions were higher than those of HPLC fingerprints for 9 batches of formula granule decoctions(P＜0.01).Adenosine,synephrine,liquiritin,hesperidin and cyclic adenosine monophosphate demonstrated higher contents in traditional decoctions than those in formula granule decoctions(P＜0.05),6-gingerol displayed lower content than that in the latter produced by manufacturers A,C(P＜0.05),which was higher than that in the latter produced by manufacturer B(P＜0.01).Various batches of traditional decoctions and formula granule decoctions could be obviously distinguished,adenosine,synephrine and hesperidin exhibited great influences on the classification of principal component analysis,and the quality of formula granule decoctions produced by manufacturer C was closer to that of traditional decoctions.After equivalent correction,the contents of various constituents in formula granule decoctions produced by manufacturers A,C showed no significant differences as compared with those in traditional decoction(P＞0.05).CONCLUSION The formula granules of Wendan Decoction from different manufacturers exist quality differences,so the preparation process and extraction process of this preparation should be optimized to improve quality,and equivalent ratio should be adjusted according to actual requirements to ensure its scientific and rational clinical application.

Objective:To develop an early exercise rehabilitation nursing for elderly patients undergoing total hip arthroplasty (THA) based on the best evidence, and explore its clinical effects.Methods:This study was a randomized controlled trial. From August to December 2022, convenience sampling was used to select 126 elderly THA patients admitted to the Department of Orthopedics of the First Affiliated Hospital of Naval Medical University as participants. Patients were divided into observation group and control group using a random number table method, with 63 cases in each group. Control group was treated with a usual exercise rehabilitation nursing, while observation group was treated with an early exercise rehabilitation nursing for elderly THA patients based on the best evidence. Changhai Pain Rating Scale, Harris Hip Score, and Barthel Index were used to evaluate pain, hip function, and activities of daily living in two groups of patients. The first time off the bed, hospital stay, and incidence of complications were recorded and compared between the two groups.Results:The Harris Hip scores of observation group patients three days after surgery and on the day of discharge were (61.13±4.82) and (77.84±4.43), respectively, which were higher than those of control group (50.75±6.19) and (70.25±7.47), and the differences were statistically significant ( t=10.502, 6.937; both P<0.01). Barthel Index scores of observation group patients were higher than those of control group on the day of surgery, three days after surgery, and the day of discharge, and the differences were statistically significant ( t=3.531, 4.609, 10.112; all P<0.01). The incidence of postoperative complications in observation group was 11.11% (7/63), while in control group it was 42.86% (27/63), with a statistically significant difference (χ 2=16.113, P<0.01). There were no statistically significant differences in the resting pain score and exercise pain score between the two groups of patients on the day after surgery ( t=-1.693, -1.354; both P>0.05). The resting pain score and exercise pain score of observation group were lower than those of control group three days after surgery and on the day of discharge, and the differences were statistically significant (all P<0.05). Observation group had a shorter first time off the bed and hospital stay (1.34±0.37) and (5.48±0.66) days compared to control group (2.13±0.48) and (6.29±0.83) days, with statistically significant differences ( t=-10.346, -6.063; both P<0.01) . Conclusions:An evidence-based early exercise rehabilitation nursing for elderly THA patients can reduce the degree of pain, minimize the occurrence of complications, shorten the first time off the bed and hospital stay, and promote recovery of elderly patient.

Researchers commonly use cyclization recombination enzyme/locus of X-over P1 (Cre/loxP) technology-based conditional gene knockouts of model mice to investigate the functional roles of genes of interest in Sertoli and Leydig cells within the testis. However, the shortcomings of these genetic tools include high costs, lengthy experimental periods, and limited accessibility for researchers. Therefore, exploring alternative gene silencing techniques is of great practical value. In this study, we employed adeno-associated virus (AAV) as a vector for gene silencing in Sertoli and Leydig cells. Our findings demonstrated that AAV serotypes 1, 8, and 9 exhibited high infection efficiency in both types of testis cells. Importantly, we discovered that all three AAV serotypes exhibited exquisite specificity in targeting Sertoli cells via tubular injection while demonstrating remarkable selectivity in targeting Leydig cells via interstitial injection. We achieved cell-specific knockouts of the steroidogenic acute regulatory ( Star ) and luteinizing hormone/human chorionic gonadotropin receptor (Lhcgr) genes in Leydig cells, but not in Sertoli cells, using AAV9-single guide RNA (sgRNA)-mediated gene editing in Rosa26-LSL-Cas9 mice. Knockdown of androgen receptor ( Ar ) gene expression in Sertoli cells of wild-type mice was achieved via tubular injection of AAV9-short hairpin RNA (shRNA)-mediated targeting. Our findings offer technical approaches for investigating gene function in Sertoli and Leydig cells through AAV9-mediated gene silencing.

The circadian clock plays a critical role in regulating various physiological processes, including gene expression, metabolic regulation, immune response, and the sleep-wake cycle in living organisms. Post-translational modifications (PTMs) are crucial regulatory mechanisms to maintain the precise oscillation of the circadian clock. By modulating the stability, activity, cell localization and protein-protein interactions of core clock proteins, PTMs enable these proteins to respond dynamically to environmental and intracellular changes, thereby sustaining the periodic oscillations of the circadian clock. Different types of PTMs exert their effects through distincting molecular mechanisms, collectively ensuring the proper function of the circadian system. This review systematically summarized several major types of PTMs, including phosphorylation, acetylation, ubiquitination, SUMOylation and oxidative modification, and overviewed their roles in regulating the core clock proteins and the associated pathways, with the goals of providing a theoretical foundation for the deeper understanding of clock mechanisms and the treatment of diseases associated with circadian disruption.

Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

As a novel iron-dependent form of cell death, ferroptosis is characterized by the excessive accumulation of phospholipids containing polyunsaturated fatty acids (PUFA) on the cell membrane and peroxidation. Lipid droplets are always in the dynamic transition of generation and decomposition, play a central role in regulating lipid metabolism, and are always in the dynamic transition of generation and decomposition. Lipid droplet metabolism is closely related to the occurrence of ferroptosis and plays an important role in the disease caused by ferroptosis. This review firstly focuses on the lipid droplet metabolism process and its effects on the storage and release of PUFA, and further elucidates the regulatory mechanism and key regulatory proteins of lipid drop metabolism on ferroptosis, in order to reveal the intrinsic relationship between lipid droplets and ferroptosis, and provide a new strategy for disease prevention and treatment.
