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.

OBJECTIVES: To investigate the effects of quercetin on cuproptosis and L-type calcium currents in the myocardium of diabetic rats. METHODS: Forty SD rats were randomized into control group and diabetic model groups. The rat models of diabetes mellitus (DM) induced by high-fat and high-sugar diet combined with streptozotocin (STZ) injection were further divided into DM model group, quercetin treatment group, and empagliflozin treatment group (n=10). Blood glucose and body weight were measured every other week, and cardiac function of the rats was evaluated using echocardiography. HE staining, Sirius red staining, and wheat germ agglutinin (WGA) analysis were used to observe the changes in myocardial histomorphology, and serum copper levels and myocardial FDX1 expression were detected. In cultured rat cardiomyocyte H9c2 cells with high-glucose exposure, the effects of quercetin and elesclomol, alone or in combination, on intracellular CK-MB and LDH levels and FDX1 expression were assessed, and the changes in L-type calcium currents were analyzed using patch-clamp technique. RESULTS: The diabetic rats exhibited elevated blood glucose, reduced body weight, impaired left ventricular function, increased serum copper levels and myocardial FDX1 expression, decreased L-type calcium currents, and prolonged action potential duration. Quercetin and empagliflozin treatment significantly lowered blood glucose, improved body weight, and restored cardiac function of the diabetic rats, and compared with empagliflozin, quercetin more effectively reduced serum copper levels, downregulated FDX1 expression, and enhanced myocardial L-type calcium currents in diabetic rats. In H9c2 cells, high glucose exposure significantly increased myocardial expressions of FDX1, CK-MB and LDH, which were effectively lowered by quercetin treatment; Elesclomol further elevated FDX1, CK-MB and LDH levels in the exposed cells, and these changes were not significantly affected by the application of quercetin. CONCLUSIONS Quercetin ameliorates myocardial injury in diabetic rats possibly by suppressing myocardial cuproptosis signaling and restoring L-type calcium channel activity.

Objective: To explore the association between greenness surrounding school and aggression among primary school students, and to explore the potential mediating roles of social support, loneliness, particulate matter (PM2.5) and Nitrogen Dioxide (NO2) in this association, in order to provide a scientific reference for preventing and ameliorating aggressive behaviors of primary school students. Methods: The data was used from a survey of children and adolescents conducted in 2015. The Chinese version of the Buss-Warren Aggression Questionnaire was used to assess total and subtypes of aggression, and the mean values of normalized difference vegetation index (NDVI) of 100 m, 500 m, 1 000 m circular buffers surrounding school were used to indicate the participants greenness exposure. PM2.5 and NO2 datas were obtained from the China High Air Pollutants Dataset.Generalized Linear Mixed Models were used to assess the associations of greenness surrounding school with total and subtypes of aggression. Results: Per IQR increment of NDVI-500 m [OR(95%CI)=1.09(1.03-1.15)] and NDVI-1 000 m[OR(95%CI)=1.07(1.02-1.13)] were positively correlated with physical aggression among primary school children, and per IQR increment of NDVI-100 m [OR(95%CI)=0.94(0.90-0.99)], NDVI-500 m [OR(95%CI)=0.93(0.89-0.98)] and NDVI-1 000 m [OR(95%CI)=0.95(0.91-1.00)] were negatively associated with verbal aggression (P<0.05). Mediation analyses revealed that social support partially mediated the association between the NDVI-500 m and physical aggression (mediation ratio:18.0%) and verbal aggression (mediation ratio:-8.3%) among primary school students, and loneliness partially mediated the association between the NDVI-500 m and physical aggression and verbal aggression among elementary school students effects, with proportion mediated ratios of -10.0% and 21.0%, respectively (P<0.05). Conclusions Exposure to school surrounding greenness is likely to associated with physical aggression and verbal aggression in primary school students, and social support and loneliness may partially mediate these associations.

Objective:To summary the clinical phenotype and genotype characteristics of 2 cases of autosomal dominant mental retardation (MRD) caused by TRIO gene variation. Methods:Retrospective study of the clinical data of 2 cases of autosomal dominant MRD caused by TRIO gene mutations diagnosed at the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University in April 2019 and January 2023 was conducted. The clinical features were summarized and gene analysis and follow-up were carried out. Results:The 2 patients were 6 years and 5 months old and 5 months old males, respectively. Clinical manifestations included seizures, cognitive and motor disorders, low intelligent development; case 1 had microcephaly, attention deficit disorder, ataxia, and aggressive behavior, and case 2 had macrocephaly. Brain magnetic resonance imaging revealed cerebellar atrophy in case 1, and non-specific dilation of the subarachnoid space and hypoplasia of the corpus callosum in case 2. Analysis of chromosome karyotype and chromosome copy number variation in 2 children showed no abnormalities. Whole exome sequencing revealed novel missense mutations in the TRIO gene in both patients [NM_007118:c.4289C>A(p.Thr1430Lys), c.4111C>A(p.His1371Asn), respectively]. The application of rehabilitation function training and a variety of anti-seizure medications can not fully and effectively control the seizure. Conclusion:TRIO gene c.4289C>A(p.Thr1430Lys), c.4111C>A(p.His1371Asn) de novo missense variants were the genetic etiology of the 2 probands,causing rare autosomal dominant MRD type 44 and 63.

Objective:To investigate the clinical characteristics of patients with combined oxidative phosphorylation deficiency type 4 (COXPD4) related to TUFM gene variation, in order to improve clinicians′ understanding of the disease. Methods:A case of COXPD4 with cystic leukodystrophy admitted to the Children′s Hospital of Zhengzhou University in June 2021 was taken as the study subject, and her clinical characteristics and genetic testing results were retrospectively analyzed. The "combined oxidative phosphorylation deficiency type 4" " TUFM gene" "cystic leukodystrophy" "combined oxidative phosphorylation deficiency 4" "COXPD 4" " TUFM" and "cystic leukodystrophy" were used as keywords, and the documents on COXPD4 related to TUFM gene mutations were reviewed from Wanfang Data Knowledge Service Platform, CNKI, PubMed Document Database, and National Center for Biotechnology Information (NCBI) until August 2021. The COXPD4 patients that have been reported internationally were analyzed for clinical features and variant types. Results:The patient was a 2-month-old girl with clinical manifestations of delayed development and progressive aggravation, elevated lactic acid in serum and cerebrospinal fluid, and diffuse white matter dysplasia with multiple cystic lesions in cerebral magnetic resonance imaging (MRI). Whole exome sequencing showed TUFM gene complex heterozygous variants c.684_684+4delGGTGA and c.1105C>T, which had not been reported in the past. A total of 5 cases of COXPD4 were reported in 4 English literatures. Together with 1 case in this study, there were 4 cases with detailed clinical history data, including 1 male and 3 females. The clinical manifestations were severe early-onset lactic acidosis and developmental lag, and 3 cases were accompanied by progressive infantile encephalopathy. Among them, 3 cases underwent head MRI examination, all of which showed diffuse white matter signal with multiple cystic lesions, 2 cases with basal ganglia involvement and multiple cerebellar gyri deformity. Genetic test indicated different types of TUFM gene variation. Conclusions:COXPD4 is a rare hereditary mitochondrial disease. For cases with COXPD4 clinical and imaging features, TUFM gene mutations can be screened first.

Objective To observe the value of conventional ultrasound combined with ultrasonic elastography for evaluating the severity of active lesions of juvenile localized scleroderma(JLS).Methods Totally 27 JLS children with 46 active lesions were prospectively enrolled.The thickness,echo and blood flow of skin and subcutaneous tissue of JLS lesions and the paired sites were evaluated using conventional ultrasound,while the skin stiffness of all lesions and paired sites were assessed using shear wave elastography(SWE),and the strain ratio of lesions and surrounding skin were evaluated using strain elastography(SE).The thickness,echo and blood flow of skin as well as subcutaneous tissue,and the Young's modulus of skin were compared between JLS active lesions and the paired sites.The correlations of the individual sum total of each Young's modulus and the limited scleroderma activity index(LoSAI)or the limited scleroderma injury index(LoSDI)were explored.Results Compared with the paired site,no significant difference of the skin thickness was found among 46 JLS lesions(P＞0.05),but JLS lesions had thinner subcutaneous tissue(P＜0.05)and greater Young's moduli(all P＜0.05).The strain ratio of the lesions and surrounding skin were all larger than 2.For JLS children with active lesions,the individual sum total of Young's moduli had moderate rank correlations with LoSAI(rs=0.63-0.69,all P＜0.05),but there was no significant rank correlation with LoSDI(rs=0.27-0.33,P＞0.05).Conclusion Compared with the paired site,JLS active lesions had thinner subcutaneous tissue and stiffer skin.The higher the lesion skin stiffness,the more severe the JLS lesion activity.

Oral squamous cell carcinoma (OSCC) is a common malignant tumor of the head and neck. In recent years, the incidence rate has been increasing. Mitochondria are dynamic organelles involved in various cell behaviors in eukaryotic cells. Mitochondrial dysfunction is closely related to tumor development. As a switch that determines cancer cell death, targeting mitochondria has become the focus of OSCC treatment. This article reviews the relationship between mitochondria and tumorigenesis and development, OSCC treatment, and cisplatin resistant OSCC. Current studies have found that mitochondrial dysfunction promotes cell carcinogenesis, and the mitochondrial morphology and function of cancer cells are significantly changed. The increase of mitochondrial fission improves the invasiveness of cancer cells, and mitophagy dysfunction can induce cancer cell apoptosis. The emergence of drugs and the development of nanotechnology in targeted drug delivery systems have opened up new methods for targeting mitochondria to treat OSCC, reducing the side effects of systemic medication. The cisplatin resistance of OSCC is generated through the mitochondrial pathway, and the mitochondrial function and mutation mechanism of mitochondrial DNA are clarified in order to provide new ideas for targeting mitochondria to treat cisplatin resistant OSCC.
