Objective: To explore the relationship of social anxiety and emotion regulation strategy with short video addiction among college students, so as to provide reference for alleviating social anxiety, improving the level of emotion regulation and preventing short video addiction. Methods: From May to June 2024, 2 172 college students from a university in Guangzhou were selected by multistage random cluster sampling method. The Interaction Anxiousness Scale, Emotion Regulation Questionnaire and Short Video Addiction Scale were used as the measurement tools. The potential profile was used to analyze the potential categories of social anxiety and emotion regulation strategy. The Chi square test was used to analyze the characteristics of the distribution of potential profile categories of college students with different demographic characteristics. Multiple linear regression analysis was used to analyze the relationship between social anxiety, emotion regulation strategy and short video addiction. Results: The potential categories of social anxiety and emotion regulation strategy in college students were divided into adaptive regulation type (784 cases, 36.10 %), low anxiety-expression type (623 cases, 28.68%), inhibition-anxiety type (478 cases, 22.01%), high anxiety-disorder type (287 cases, 13.21%). There were statistically significant differences in the distribution of various potential categories of social anxiety and emotion regulation strategy among cadres of different gender, family residence, class cadres or not ( χ 2=42.55, 17.86 , 39.05, all P <0.01). Multiple linear regression analysis showed that after controlling the confounding factors such as demographic variables, the potential categories of social anxiety and emotion regulation strategy of college students (low anxiety-expression type, inhibition-anxiety type, high anxiety-disorder type) were the important related factors of short video addiction ( β =0.15,0.25,0.35, all P <0.05). Conclusions Social anxiety and emotion regulation strategy of college students exhibit distinct categorical characteristics, and its varying latent categories are associated with short video addiction. Schools should implement targeted intervention measures for different categories of college students to promote their comprehensive mental health development.

Objective: To analyze the cause of discrepancy between ABO genotype B102/O01 and serological results in one case by PCR-SSP, to clarify the serological characteristics of this special blood group, and to explore relevant blood transfusion strategies. Methods: Blood group serological tests were performed on blood donor in August and December 2024, including forward and reverse ABO typing using tube method, H antigen identification, direct anti-human globulin test by tube method, red blood cell absorption-elution test, and determination of ABH blood group substance in saliva. Exons 1-7 of the ABO gene were amplified by PCR-SSP and sequenced. Results: The two separate serological tests consistently identified the donor as having an A B phenotype, but the results of gene sequencing indicated a B102/O01 genotype, showing an discrepancy between serological and genetic results. Conclusion: It is very likely that the blood type of the blood donor is B102/O01 with a microchimerism of type A, or an AB type masked by A type reference gene.

Chronic heart failure （CHF） is an end-stage cardiac syndrome driven by multiple factors. Its pathological process involves interactions of multiple pathways such as energy metabolism dysfunction， neuroendocrine dysregulation， and myocardial fibrosis. Although current clinical medicine can alleviate symptoms through single-target approaches， significant limitations in reversing cardiac remodeling and disease progression remain. Puerarin， a major bioactive isoflavone constituent derived from Pueraria lobata， exhibits multidimensional pharmacological effects， such as vasodilatory effects， regulation of neuroendocrine balance， enhancement of metabolic homeostasis， and suppression of myocardial apoptosis. This review systematically integrated puerarin's multi-target regulatory network， elucidating its mechanisms such as improving energy metabolism by AMP-activated protein kinase/mechanistic target of rapamycin （AMPK/mTOR） pathway， inhibiting fibrosis mediated by transforming growth factor-β （TGF-β）/Smad signals， and attenuating oxidative-inflammatory cascades by regulating nuclear factor erythroid 2 （E₂）-related factor 2/nuclear transcription factor-κB（Nrf2/NF-κB） axis. Clinical research data was used to validate its efficacy in improving the left ventricular ejection function and reducing the therapeutic potential of cardiovascular events' risks. The study proposed that puerarin's "systemic regulation" characteristic breaks through the limitations of traditional single-target drugs and prospected its clinical translation pathway based on metabolomics and nano-delivery technology， offering an integrative perspective from molecular mechanisms to precise therapy for the research on modernization of traditional Chinese medicine.

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 investigate the potential efficacy and safety of Lutai Danshen Baishao granules (LDBG) for treating female melasma associated with kidney deficiency and blood stasis patterns. Methods: A randomized, double-blind, placebo-controlled trial was conducted at the Third Central Hospital of Tianjin, China from March to December 2023. A total of 110 female patients with melasma linked to kidney deficiency and blood stasis were enrolled and treated with either LDBG or a placebo twice daily for 60 days. Efficacy was assessed through measures such as the total melasma area, reduced melasma area, reduction rate of melasma area, melasma color score, Melasma Area and Severity Index (MASI) score, and traditional Chinese medicine (TCM) symptom score scale. Safety assessments included routine blood and biochemical tests. Results: Participants in both groups were aged 52–63 years, with no significant differences. After the 2-month intervention, the total melasma area decreased in both groups; however, a greater reduction was observed in the test group [462.50 mm2 (12.81%) vs. 100.00 mm2 (3.11%), P < .001]. Moreover, LDBG treatment significantly reduced the MASI and melasma color scores in the test group (P < .05). The total TCM symptom evaluation score significantly decreased (test group: 6.00 vs. placebo group: 7.00, P = .001), with significant relief in symptoms such as improvement in dark lips, nails, and waist soreness in the test group, compared with that in the placebo group (P < .05). Within-group comparisons revealed that TCM syndrome was significantly alleviated in the test group (P < .05). Conclusion LDBG intervention shows promising effectiveness in reducing female melasma and alleviating TCM syndromes.

Objective: To compare and analyze the antibacterial effects of platelets against five common clinical pathogenic bacteria including MRSA, SE, SA, E. coli, and CRKP, and to preliminarily explore the role of DCD sensitivity in the observed variations of antibacterial effects. Methods: The same number of platelets were used to establish co-culture systems of platelets and platelet lysates with the five pathogenic bacteria. The antibacterial effects of platelets and platelet lysates on the five pathogenic bacteria were evaluated by observing the turbidity of the bacterial solution, measuring the OD value of the bacterial solution and counting the colonies. The supernatant protein of platelets co-cultured with MRSA was collected for quantitative proteomics analysis to explore the important antibacterial proteins of platelets. The content of DCD in the supernatant after co-culture of platelets and platelet lysates with the five pathogenic bacteria was detected by ELISA to preliminarily analyze the reasons for the different antibacterial effects of platelets on the five pathogenic bacteria. Results: Compared with the control group of MRSA, SA, and SE, the turbidity of the bacterial solution decreased after co-culture of platelets and platelet lysates with MRSA, SA, and SE for 12 h, and the OD value and colony count were significantly reduced (P<0.05). The turbidity of the bacterial solution did not change significantly after co-culture of platelets and platelet lysates with E. coli for 24 h, but the OD value decreased (P<0.05), and the colony count decreased to 10 CFU/mL but the difference was not statistically significant (P>0.05). Compared with the control group of CRKP, the turbidity, OD value, and colony count of the bacterial solution did not change significantly after co-culture of platelets and platelet lysates with CRKP (P>0.05). Proteomics results showed that after co-culture with MRSA, important proteins related to platelet activation, including collagen, fibrinogen, von Willebrand factor, integrin αIIbβ3, platelet glycoprotein V and IV were significantly up-regulated. ELISA results showed that after co-culture with the five pathogenic bacteria, platelets could secrete a large amount of DCD, with the content around 3 μg/mL. Conclusion: The antibacterial effect of platelets on Gram-positive bacteria MRSA, SA, and SE is better than that on Gram-negative bacteria E. coli and CRKP, and platelets have the best antibacterial effect on MRSA. The differences in antibacterial effects of platelets on the five pathogenic bacteria may be related to the sensitivity of DCD antibacterial peptides to the five pathogenic bacteria.

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.

ObjectiveTo explore the possible mechanism of Qishao Tongbi Capsule （芪芍通痹胶囊， QTC） in the treatment of intervertebral disc degeneration （IDD）. MethodsSeventy-five rats were randomly divided into control group， model group， low-dose QTC group， high-dose QTC group， high-dose QTC +agonist group， with 15 rats in each group. Except for the control group， all other groups were subjected to a fibrous ring puncture to prepare an IDD model. After modeling， rats in low-dose QTC group and high-dose QTC group were given QTC at doses of 0.2 and 0.8 g/（kg·d） by gavage， respectively. Rats in high-dose QTC+ agonist group was given QTC at 0.8 g/（kg·d） and SKL2001 solution at 10 mg/（kg·d） by gavage. The control group and model group were given 10 ml/（kg·d） distilled water by gavage. All treatments were given once a day for 4 consecutive weeks. After treatment， X-ray and magnetic resonance imaging （MRI） were used to detect IDD degree. Hematoxylin-eosin （HE） staining and Safranin O-Fast Green staining were used to observe the morphological changes of the intervertebral disc tissue. Immunohistochemical staining was performed to examine the levels of proteoglycan， type Ⅱ collagen （COL Ⅱ）， and matrix metalloproteinase-3 （MMP-3） in the intervertebral disc tissue. Western blotting was used to detect the extracellular matrix （ECM）-related proteins （proteoglycan， COL Ⅱ， MMP-3， MMP-9， MMP-13）， aging-related proteins （P53， P21， P16）， apoptosis related proteins， including B-cell lymphoma/leukemia 2 （BCL-2）， BCL-2 related X protein （BAX）， Cleaved Caspase-3， and Wnt/β-catenin pathway related proteins such as Wnt3a， glycogen synthase kinase-3β （GSK-3β） and β-catenin in the intervertebral disc nucleus pulposus （NP） tissue. Reverse Transcription Quantitative Polymerase Chain Reaction （RT-qPCR） was used to assess the mRNA expression of Wnt3a， GSK-3β， and β-catenin in intervertebral disc tissue. ResultsCompared with the model group， rats in the low-dose QTC group and high-dose QTC group exhibited improved DHI， decreased Pfirmann grading， and alleviated IDD. The structural integrity of the NP and annulus fibrosus increased， and the number of the NP increased. The levels of proteoglycan， COL Ⅱ， BCL-2 and GSK-3β increased， while the levels of MMP-3， MMP-9， MMP-13， P53， P21， P16， BAX， Cleaved Caspase-3， Wnt3a and β-catenin protein decreased. The mRNA expression of Wnt3a and β-catenin mRNA decreased， while GSK-3β mRNA expression increased （P＜0.05）. Compared with the low-dose QTC group， the high-dose QTC group showed further improvements in DHI， decrease in Pfirrmann grading （P＜0.05）， and greater alleviation of IDD. The structural integrity of NP and annulus fibrosus was further enhanced， and the number of NP cells further increased. The levels of proteoglycan， COL Ⅱ， BCL-2 and GSK-3β were higher， while the levels of MMP-3， MMP-9， MMP-13， P53， P21， P16， BAX， Cleaved Caspase-3， Wnt3a and β-catenin were lower. The mRNA expression of Wnt3a and β-catenin decreased， while GSK-3β mRNA expression increased （P＜0.05）. Compared with the high-dose QTC group， the high-dose QTC +agonist group showed a decrease of DHI， an increase of Pfirmann grading （P＜0.05）， significant aggravation of IDD， reduction in structural integrity of the NP and annulus fibrosus， a decrease of NP cell count， lower levels of proteoglycan， COL Ⅱ， BCL-2 and GSK-3β， and higher levels of MMP-3， MMP-9， MMP-13， P53， P21， P16， BAX and Cleaved Caspase-3. Additionally， GSK-3β mRNA expression decreased （P＜0.05）. ConclusionQTC can inhibit NP cell aging， apoptosis， and ECM degradation in IDD rats， and its therapeutic effect may be mediated through the inhibition of the Wnt/β-catenin pathway.
