The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

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.

AIM:To test and compare the perceptual eye position and fixation stability of adolescents with emmetropia and adolescents with low myopia, investigating the characteristics of the perceptual eye position and fixation stability of adolescents with low myopia.METHODS: Cross-sectional study. A total of 132 adolescents(264 eyes)who visited in the ophthalmology clinic of our hospital from April to December 2023 were randomly selected as the research subjects. Participants were categorized into normal control group(n=45, 90 eyes), simple low myopia group(n=45, 90 eyes)and low myopia with anisometropia group(n=42, 84 eyes)according to their refractive status and were underwent assessments for perceptual eye position and fixation stability.RESULTS: Compared with the normal control group, the static and dynamic horizontal perceptual eye position deviation of the simple low myopia group and the low myopia with anisometropia group were significantly increased(P<0.05). Compared with the simple low myopia group, the static and dynamic horizontal perceptual eye position deviation of the low myopia with anisometropia group were significantly increased(P<0.05). There was no significant difference in static and dynamic vertical perceptual eye position deviation among the three groups(P>0.05); compared with the normal control group, the horizontal and vertical fixation stability of the simple low myopia group and the low myopia with anisometropia group were significantly worse(all P<0.01), but there was no differences in the simple low myopia group and the low myopia with anisometropia group(P >0.05).CONCLUSION: Abnormalities are observed in perceptual eye position and fixation stability function in adolescents with low myopia compared with those adolescents with emmetropia, even at best corrected visual acuity. The occurrence of anisometropia could lead to an increased degree of horizontal perceptual eye position displacement.
