Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.

Objective:To observe alterations in center retinal thickness (CRT) in patients diagnosed with central retinal artery occlusion (CRAO) before and after undergoing superselective arterial thrombolysis (IAT) treatment.Methods:A retrospective clinical study. From August 2022 to September 2023, 12 patients (12 eyes) diagnosed with CRAO and treated with IAT at the ophthalmology department of Shenzhen Second People's Hospital. Among these patients, there were 8 males (8 eyes) and 4 females (4 eyes), all experiencing unilateral onset. The mean age was (47.00±15.06) years. The mean duration from onset to thrombolysis was (30.00±30.42) h. All eyes underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) assessments; additionally, 6 eyes underwent Fluorescein fundus angiography (FFA). BCVA assessments were conducted using a standard logarithmic chart and transformed into logarithm of the minimum angle of resolution (logMAR) values for statistical analysis. The OCT measured CRT at various locations around the macular fovea (M), including upper (S1, S3), lower (I1, I3), nasal (N1, N3), and temporal (T1, T3) areas at 1 mm and 3 mm distances from the fovea. CRT was defined as the vertical distance between the inner retinal boundary membrane and the inner interface of the retinal pigment epithelial layer. Pre- and post-IAT examinations were performed using the same equipment and methodologies within a 24-hour interval. Changes in CRT at different macular points were compared and observed, while arterial imaging time changes were assessed in 6 eyes that underwent FFA. Paired t-tests were utilized to analyze logMAR BCVA, CRT at different locations, and arterial imaging time pre- and post-treatment. Results:Prior to IAT treatment, the logMAR BCVA for the affected eye was 3.48±1.42, while the arterial imaging time for the 6 eyes undergoing FFA examination was (27.50±5.47) s. After 24 hours, the logMAR BCVA had improved to 2.35±1.59 for the affected eye, with 9 eyes showing varying degrees of BCVA improvement. The arterial imaging time was (24.17±7.28) s post-treatment. The differences in logMAR BCVA and arterial imaging time before and after treatment were found to be statistically significant ( t=2.489, 3.262; P<0.05). Additionally, the comparison of CRT at S3 ( t=2.871), I1 ( t=2.325), and T3 ( t=3.446) before and after treatment yielded statistically significant differences ( P<0.05). Conversely, the comparison of CRT at S1 ( t=1.879), I3 ( t=1.915), N1 ( t=2.001), N3 ( t=1.987), T1 ( t=2.180), and M ( t=-0.490) showed no statistically significant differences ( P>0.05). Conclusions:IAT treatment for CRAO has been shown to be effective in achieving therapeutic effects by reducing CRT in the macular area. However, the short-term improvement in retinal edema in the macular area is limited.
