		                        			Androgen deprivation therapy (ADT) is considered the standard treatment for advanced and metastatic prostate cancer.The most commonly used drugs in this therapy are gonadotropin hormone-releasing hormone (GnRH) agonists and GnRH antagonists. Both types of drugs exert their therapeutic effects through the endocrine system,but their mechanisms of action differ significantly. GnRH agonists activate the GnRH receptor,leading to a negative feedback mechanism,whereas GnRH antagonists directly bind to the GnRH receptor and block the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These differences result in varying clinical outcomes. This paper provides a systematic comparison of the two types of drugs in terms of efficacy,safety,adverse events,and improvements of lower urinary tract symptoms (LUTS) in different clinical scenarios. Additionally,the paper also discusses the benefits of switching between these two treatment options and the future directions of ADT,aiming to offer practical insights to clinicians for the optimal use of these therapies.

		                        			This study examined the effect of islet macrophages on β-cell function changes during type 2 diabetes mellitus (T2DM) progression based on the traditional Chinese medicine theory that " moderate fire generating qi, hyperactive fire consuming qi" . T2DM is closely associated with chronic low-grade inflammation, with islet macrophages playing a central role in this process. Under physiological conditions, islet macrophages secrete anti-inflammatory and growth factors to regulate the immune response, promote cell proliferation, and support islet β-cell survival and function, reflecting the concept of " moderate fire generating qi" . However, during the pathological process of T2DM, islet macrophages become over-activated and dysfunctional, secreting large amounts of pro-inflammatory factors that trigger severe inflammatory responses and oxidative stress. This process damages islet β-cells, disrupts the islet microenvironment and blood supply, exacerbates local inflammation and structural damage, and worsens the survival environment of β-cells. Ultimately, this leads to fewer β-cells and function loss, aligning with the " hyperactive fire consuming qi" theory, where excessive fire depletes qi and blood. This study enhances the understanding and application of traditional Chinese medicine theories in modern medicine, offering a new perspective on T2DM prevention and treatment. Regulating islet macrophage function and reducing their pro-inflammatory responses may become key strategies for preserving β-cell function and slowing T2DM progression.

		                        			Objective:
		                        			To evaluate the efficacy and safety of Jiawei Simiao powder (JWSMP) combined with celecoxib for the treatment of acute gouty arthritis by conducting a meta-analysis of randomized controlled trials (RCTs).
		                        		
		                        			Methods:
		                        			The Chinese National Knowledge Infrastructure Databases, Chinese Scientific Journal Database, Wanfang, Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched from inception until December 2023. Continuous variables were analyzed using the mean difference (MD) for analysis, and dichotomous variables were used as risk ratios. Data with similar characteristics were pooled for meta-analysis, and heterogeneity was assessed using I2. The Cochrane Handbook was used to assess the risk of bias and quality. RevMan 5.3 software was used to perform the meta-analysis.
		                        		
		                        			Results:
		                        			Thirteen RCTs involving 1007 patients were included in the study. The quality of the included studies was low (unclear randomization processes and insufficient blinding reporting). The group receiving JWSMP combined with celecoxib showed significantly lower levels of serum uric acid (SUA, MD = −66.32, 95% confidence interval (CI): −80.97 to −51.67, P < .001), erythrocyte sedimentation rate (ESR, MD = −6.05, 95% CI: −8.29 to −3.82, P < .001), C-reactive protein (CRP, MD = −7.39, 95% CI: −11.15, −3.63, P < .001), and joint pain score (VAS score, MD = −2.14, 95% CI: −2.4 to −1.88, P < .001) compared to celecoxib alone. Additionally, the JWSMP combined group had a higher total effective rate (risk ratio = 1.22, 95% CI: 1.14 to 1.29, P < .001) and fewer adverse compared to celecoxib alone.
		                        		
		                        			Conclusions
		                        			JWSMP combined with celecoxib is more effective than celecoxib alone in improving the total efficacy rate, alleviating joint pain, and improving SUA, ESR, and CRP levels. JWSMP also reduced the occurrence of adverse events caused by celecoxib. However, the quality of the included studies was low, highlighting the need for further high-quality research with larger sample sizes and robust methodologies, such as double-blind randomization, to confirm these findings.

		                        			Objective:To summarize the best evidence for the use of ankle pump exercises in preventing perioperative lower limb deep vein thrombosis (DVT) in patients undergoing joint replacement surgery and to evaluate its clinical application.Methods:This study utilized an evidence-based continuous quality improvement model. A systematic search was conducted for relevant clinical practice guidelines, expert consensus, systematic reviews, and randomized controlled trials (RCTs) from both domestic and international sources. The best evidence was evaluated and summarized, and audit indicators were developed for baseline assessments. Facilitating and hindering factors were analyzed based on the baseline results. From December 2022 to April 2023, the evidence was applied in the Department of Orthopedics at Henan Provincial People's Hospital. The pre-evidence group for baseline assessments included 36 joint replacement patients and 18 nurses from the orthopedic unit between December 2022 and January 2023, while the post-evidence group included 36 joint replacement patients and the same 18 nurses between March and April 2023. The knowledge level of nurses, the effectiveness of ankle pump exercises, the execution rate, and patient compliance were compared before and after evidence-based practice.Results:A total of 12 articles were included in the study, comprising one clinical practice guideline, five expert consensus papers, one systematic review, and five RCTs. Ten best practices were summarized in terms of applicable populations, exercise assessment, exercise positions, timing, methods, frequency, and patient education. After implementing evidence-based practice, the knowledge scores of nurses on ankle pump exercises significantly improved from (70.56±9.98) to (82.78±8.26) ( P<0.01). The compliance rates of audit items 2, 3, 4, 5, and 6 among nurses increased from 0, 22.2%, 0, 27.8%, and 11.1% respectively, to 94.4%, 94.4%, 83.3%, 100.0%, and 100.0% respectively ( P<0.01). On the patient side, the compliance rates for audit items 7 and 8 increased from 5.6% and 0 to 86.1% and 94.4%, respectively ( P<0.01) . Conclusions:Implementing evidence-based ankle pump exercises to prevent DVT in joint replacement patients can significantly improve nurses' knowledge of evidence-based practice, standardize the practice of ankle pump exercises, and explore balanced educational strategies that enhance patient compliance, ensuring clinical practices are evidence-based.
