Objective: Randomized controlled trials (RCTs) of Chinese patent medicines and classic traditional Chinese medicine prescriptions were systematically reviewed from both Chinese and English journals published in 2023. A preliminary summary and evaluation were conducted on the generation and translation of clinical evidence for these treatments. This analysis aims to inform future research on clinical efficacy evaluation and guide the rational application of evidence. Methods: RCTs of Chinese patent medicines and classic traditional Chinese prescriptions published in 2023 were comprehensively retrieved from the Artificial Intelligence Clinical Evidence Database for Chinese Patent Medicine (AICED-CPM), with supplementary searches conducted in China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Science and Technology Journal Database (VIP), Chinese Biomedical Literature Database (SinoMed), Cochrane Library, PubMed, Embase, and Web of Science. The study characteristics and methodological quality of these RCTs were systematically analyzed and evaluated. Results: A total of 1 443 RCTs of Chinese patent medicines were included, comprising 1 399 Chinese articles and 44 English articles. Additionally, 334 RCTs of classic traditional Chinese medicine prescriptions were found, with 331 published in Chinese and 3 in English. 196 567 participants were included, covering 585 types of Chinese patent medicines (487 oral, 61 injectable, and 37 topical) and 179 classic traditional Chinese medicine prescriptions. The involved studies encompassed 22 types of diseases, with research primarily focusing on diseases of the circulatory system, the respiratory system, and the genitourinary system. The sample sizes ranged from 18 to 3 777 participants, and most studies were conducted at a single center. Methodologically, the implementation of allocation concealment and blinding remained insufficiently emphasized. Conclusion Overall, compared with 2022, both the number of RCT publications and their methodological quality have improved in 2023, with heightened attention to research on diseases of the genitourinary system. However, quality control and standardized management in the design and implementation processes still require enhancement to produce more high-quality clinical evidence and accelerate the translation and application of this evidence.

Objective: To explore the causal relationship between academic procrastination, negative emotions, self control, and smartphone addiction among college students, so as to provide theoretical reference for promoting their mental health and academic achievement. Methods: A multi stage cluster random sampling method was used to select 452 first year students from a university in Guangzhou as the research subjects. Procrastination Assessment Scale- Student (PASS), The Depression Anxiety Stress Scale (DASS-21), Self Control Scale, and Short Version of the Smartphone Addiction Scale (SAS-SV) were used as measurement tools. Three questionnaire surveys were completed in October 2024 (T1), February 2025 (T2), and May 2025 (T3). Coss lagged models were utilized to analyze the causal relationship between academic procrastination, negative emotions, self control, and smartphone addiction. Results: The SAS-SV scale for college students showed an average score of (40.52±1.96), with 43.1% of freshmen exhibiting smartphone addiction.Positive correlations were observed between academic procrastination, negative emotions, and smartphone addiction across different time points, while self control exhibited negative correlations with these three variables ( r = 0.30 -0.62, -0.72 to -0.34, all P <0.05). Cross lagged model results indicated that academic procrastination and negative emotions at T1 and T2 positively predicted smartphone addiction at T2 and T3 (T1→T2, β =0.22, 0.35; T2→T3, β =0.21, 0.24; all P < 0.05 ). Self control negatively predicted smartphone addiction (T1→T2, β =-0.32; T2→T3, β =-0.26; both P <0.05). In reverse causality regression models, smartphone addiction at T1 and T2 positively predicted academic procrastination and negative emotions at T2 and T3 (T1→T2, β =0.09, 0.24; T2→T3, β =0.10, 0.35; all P <0.05), but no statistically significant predictions were found for self control (T1→T2, β =-0.04; T2→T3, β =-0.03; both P >0.05). Conclusion Academic procrastination and negative emotions exhibit bidirectional causality with smartphone addiction among college students, while self control unidirectionally predicts smartphone addiction.

Objective To investigate the quality and in vitro release behavior of the sirolimus self-microemulsion-mesoporous silicon sustained release tablets and provide a basis for further research and development of related preparations. Methods The hardness, brittleness and content uniformity of the sustained-release tablets were tested refer to Pharmacopoeia of the People’s Republic of China 2020. Different diameters （10, 11, 12 mm）, different hardness （50, 70, 90 N）, different speed （50, 75, 100 r/min）, different dissolution methods （pulp method, basket method） were investigated. The release conditions of the sustained-release tablets with different pH solution （distilled water solution and 0.4% SDS solution with pH of 1.2, 4.5 and 6.8, respectively） and the in vitro release conditions of the sustained-release tablets were observed. Results The hardness, brittleness and content uniformity of the self-made sustained-release tablets were qualified; different diameters and dissolution methods had no effect on the drug release behavior of the sustained-release tablets in vitro, while the different hardness, different rotational speed and the different pH release media had certain effects. Conclusion The sirolimus self-microemulsion-mesoporous silicon sustained release tablets had good sustained-release effect in vitro and was deserved to further study.

Objective:To explore the correlations of brain network functional connectivity (FC) alterations with cerebrospinal fluid (CSF) pathological biomarkers in patients with Alzheimer's disease (AD).Methods:A total of 39 patients with cognitive impairment, admitted to Department of Neurology, Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2020 to December 2022 were recruited; 23 patients were with AD and 16 with non-AD. Clinical data were compared between the 2 groups. Resting-state functional MRI (rs-fMRI) data were collected, and FC differences between brain networks and FC differences within brain networks were compared by independent component analysis. Correlations of FC differences between brain networks and FC differences within brain networks with concentrations of β-amyloid protein 1-42 (Aβ 1-42) and Tau protein in CSF were analyzed. Results:Compared with the non-AD group, AD group had significantly lower Aβ 1-42 in CSF ( P<0.05). Compared with those in the non-AD group, FC alterations between the left frontoparietal network (lFPN) and anterior default mode network (aDMN) and between the visual network (VN) and posterior cingulate cortex (PCC), as well as FC alterations in lFPN, were significantly increased in AD group ( P<0.05). Compared with those in the non-AD group, FC alterations between lFPN and cerebellar network (CEN), and FC alterations in aDMN, sensorimotor network (SMN) and VN were significantly decreased in AD group ( P<0.05). In AD group, FC in SMN was positively correlated with total Tau and phosphorylated-Tau181 in CSF ( P<0.05); FC between VN and PCC was positively correlated with total Tau in CSF ( P<0.05). CSF Aβ 1-42 was positively correlated with FC alterations in aDMN and VN, but negatively correlated with FC in FPN ( P<0.05). Conclusion:In AD patients, characteristic changes in FC within and between multiple brain networks are noted, which are related to changes of Tau protein and Aβ 1-42 in CSF.

Objective To investigate the expression of lncRNA SENCR in aortic dissection(AD)tissues of AD patients and its effect on and mechanism in the proliferation apoptosis of human vascular smooth muscle cells(HVSMCs).Methods HE staining was done to detect the pathological changes of AD tissues.Fluorescence in situ hybridization(FISH)and RT-qPCR were used to determine the expression of SENCR in the AD tissue and HVSMCs and the expression of SENCR and miR-206 in the tissues,respectively.HVSMCs were cultured and trans-fected with pcDNA3.1-SENCR overexpression plasmids,or pcDNA3.1 blank plasmid.Then cell proliferation and apoptosis were detected by CCK-8 method and Annexin V/PI double staining flow cytometry assay,respectively.Double luciferase report verified the targeting relationship between SENCR and miR-206.Results SENCR was mainly located in the cytoplasm and nucleus of HVSMCs.Compared with the normal tissue,the expression of SENCR in the AD tissues was down-regulated(P＜0.01),but the expression of miR-206 was up-regulated(P＜0.01).Overexpressed SENCR decreased the cell proliferation of HVSMCs(P＜0.01),but significantly increased the cell apoptosis of HVSMCs(P＜0.01).SENCR could target and negatively regulate miR-206.Conclusion The expression of SENCR is down-regulated in AD tissues,and overexpressed SENCR may inhibit the proliferation and promote the apoptosis of HVSMCs by targeting down-regulated miR-206.

Diabetic ulcer (DU), one of the common and serious complications in patients with diabetes mellitus, often leads to infection, necrosis and amputation, and has a long and costly treatment period. Because of DU's unclear healing mechanism and the difficulty of delayed healing, its treatment and management have been a major challenge in clinical medicine. In recent years, the potential role of mitochondrial autophagy in DU has become a research hotspot with the in-depth study of mitochondrial autophagy mechanism. Previous studies have shown that mitochondrial autophagy is an important intracellular self-repair mechanism that plays a crucial role in maintaining cellular health and functional stability. During the development of DU, mitochondrial autophagy plays multiple roles in attenuating oxidative stress and inflammatory responses, maintaining mitochondrial functional homeostasis, influencing cell proliferation and repair capacity during DU healing, promoting DU healing, and enhancing antimicrobial capacity. In this paper, we illustrate the multiple roles played by mitochondrial autophagy in DU prevention and treatment, as well as the potential applications of mitochondrial autophagy in DU therapy. It is expected to provide a basis for the clinical application of mitochondrial autophagy in DU treatment, and provide more effective strategies and solutions for the treatment of DU.

Objective To investigate the effect and underlying mechanism of roxadustat on apoptosis and senescence of renal tubular epithelial cell line HK-2 induced by heat stress.Methods After HK-2 cells were treated with different concentrations of roxadustat(10,20,30,40 and 50 μmol/L)for 24 h,CCK-8 assay was used to determine the optimal intervention concentration of roxadustat.HK-2 cells were divided into 4 groups(n=3):control group,roxadustat group(30 μmol/L,24 h),heat-stress group(43 ℃,2 h),and heat-stress+roxadustat group(30 μmol/L roxadustat treatmnet for 24 h followed by heat-stress 2 h).Cell viability was detected by CCK-8 assay.Expression of hypoxia-inducible factor-1α(HIF-1α),Cleaved Caspase-3,p16 and p21 at protein level was detected by Western blotting.Immunofluorescence assay was employed to observe the distribution of HIF-1α.β-galactosidase staining kit was utilized to detect SA-β-Gal activity.TUNEL staining was used to measure cell apoptosis.Results The highest cell viability was observed in the cells after 30 μmol/L roxadustat treatment.Heat stress resulted in a significant decrease in cell viability(P＜0.05),elevated protein levels of HIF-1α,Cleaved Caspase-3,p16 and p21(P＜0.05),enhanced SA-β-Gal activity(P＜0.05)and increased percentage of TUNEL-positive cells(P＜0.05)when compared with the cells in the control group.In comparison with the heat-stress group,the heat-stress+roxadustat group showed significant decrease in the protein levels of Cleaved Caspase-3,p16 and p21(P＜0.05),reduced activity of SA-β-Gal[(65.44±5.00)％vs(77.15±2.61)％,P＜0.05]and decreased percentage of TUNEL-positive cells[(16.73±2.20)％vs(46.40±13.87)％,P＜0.05],but increase in cell viability[(86.33±4.51)％vs(66.33±8.50)％,P＜0.05]as well as HIF-1α protein expression(P＜0.05).Furthermore,immunofluorescence assay showed that HIF-1α was mainly distributed in the nucleus and perinucleus.Conclusion Roxadustat attenuates heat stress-induced apoptosis and senescence of renal tubular epithelial cells by upregulating HIF-1α.

ObjectiveTo explore the application effect of Jianpi Huoxue prescription combined with acupuncture in patients with chronic atrophic gastritis （CAG） of gastric blood stasis type. MethodA total of 86 patients with CAG admitted to Wuhan First Hospital from November 2021 to March 2023 were selected and randomly divided into two groups. The control group was treated with conventional Western medicine， while the observation group was treated with Jianpi Huoxue prescription combined with acupuncture. The clinical efficacy， traditional Chinese medicine （TCM） syndrome score， pathological score， negative conversion rate of Helicobacter pylori （Hp）， inflammatory indicators ［neutrophils/lymphocytes （NLR） and interleukin （IL）-1β］， changes in levels of gastric protease （PG） Ⅰ， PG Ⅰ/PG Ⅱ， and gastrin-17 （G-17）， and drug safety during treatment were observed after treatment in both groups. ResultAfter treatment， the total effective rate of the observation group ［95.35% （41/43）］ was significantly better than that of the control group ［79.07% （34/43）］， and the difference was statistically significant （χ²=5.108， P<0.05）. After treatment， the scores of the primary and secondary TCM syndromes in the observation group and the control group were significantly decreased （P<0.05）. After treatment， the scores of primary and secondary TCM syndromes in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia were significantly lower in the observation group and control group （P<0.05）. After treatment， the pathological scores of gastric mucosa atrophy， activity， chronic inflammation， intestinal metaplasia， and dysplasia in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the Hp conversion rate in the observation group was significantly increased compared with the control group （P<0.05）. After treatment， the levels of inflammatory indicators NLR and IL-1β in the observation group and control group were significantly lower （P<0.05）， and the levels of inflammatory indicators NLR and IL-1β in the observation group were significantly lower than those in the control group （P<0.05）. After treatment， the levels of PGI and PGⅠ/PGⅡ in the observation group and control group were significantly higher （P<0.05）， and the levels of PGI and PGⅠ/PGⅡ in the observation group were significantly higher than those in the control group （P<0.05）. After treatment， the G-17 level of the observation group and the control group was different at different time points （P<0.05）， and the G-17 level of the observation group was higher at different time points than that of the control group （P<0.05）. The G-17 level of the observation group had an increasing trend compared with the control group （P<0.05）. There was no significant difference in the risk of adverse reactions between the two groups. ConclusionThe combination of Jianpi Huoxue prescription and acupuncture can effectively alleviate symptoms， increase Hp negative conversion rate， inhibit inflammation， and regulate PG and G-17 levels in CAG patients， thus controlling or even reversing gastric mucosal atrophy and reducing the probability of its progression to gastric cancer.

Objective To observe the incidence of pericardial tamponade(PT)after left atrial appendage closure(LAAC)in patients with non-valvular atrial fibrillation(NVAF),and to explore its related factors and outcomes.Methods NVAF patients who were hospitalized and treated with LAAC in Department of Cardiology of our hospital from August 2014 to March 2023 were selected for the study.The general clinical data,preoperative transthoracic echocardiography and transesophageal echocardiography data,results of routine preoperative laboratory tests,intraoperative data and follow-up data of the patients were collected through the hospital medical record management system.The enrolled patients were classified into the non-PT group(n=8)and the PT group(n =1184)according to whether PT occurred after LAAC or not.The incidence of PT,related risk factors and outcomes were statistically analyzed.Results This study included 639 males(53.6%)and 553 females(46.4%),with an average age of 68.1±9.65 years.The CHA2 DS2-VASc score was 4.51±1.72,and the HAS-BLED score was 3.36±1.09.PT occurred in 8 cases(0.67%),among them,6 cases occurred 1 to 33 h after LAAC,and 2 cases occurred on day 19 and day 27 after LAAC.As for the results of transesophageal echocardiography(TEE)and LAA angiography,compared with the non-PT group,the PT group had the significantly larger maximum caliber of the LAA(P=0.025,P=0.015),smaller maximum depth of the LAA(P=0.028,P=0.031),and lower success rate of one-time placement of the occluder(P=0.031);The occluder compression rate of the PT group was significantly greater than that of the non-PT group(P=0.046).Multivariate analysis showed that larger maximum diameter of LAA,smaller average effective depth of LAA and larger compression rate of occluder were the main risk factors for PT.All the 8 PT patients were cured by stopping antithrombotic drugs,pericardiocentesis or surgical drainage.During a mean follow-up of 39±27 months,there were no device-related thrombosis(DRT),ischemic stroke,systemic embolism and other complications in the PT group.Conclusion The incidence of PT after LAAC is low,which is related to the large diameter of LAA,the relatively insufficient depth of the LAA and the large compression rate of the occlude.PT can be cured by stopping antithrombotic drugs and pericardiocentesis/surgical drainage.
