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.

Tic disorders（TD）are common neurodevelopmental disorders whose pathogenesis is unknown.As a non-invasive examination，electroencephalography（EEG）is widely used in the diagnosis of TD.Due to the high temporal resolution of the EEG signal，when combined with standardized analysis techniques，it can not only be used to understand the physiological functions of the subject，but also to reflect the pathophysiological changes of the disease.Based on the data analysis technology of EEG，this paper reviews the progress of brain connectivity and brain network analysis，time-frequency analysis，and EEG complexity of TD，summarizes the shortcomings of existing research，and provides new ideas for further in-depth study of its pathophysiological mechanism.

Objective:To explore the changes in entero-insular axis function and its role in mice with severe burns.Methods:This study was an experimental study. Ninety C57BL/6J male mice aged 8-10 weeks were divided into sham injury group and burn group (with 45 mice in each group) according to the random number table. A full-thickness scald (hereinafter referred to as burn) wound of 30% of the total body surface area was created on the back of mice in burn group, and the mice in sham injury group were simulated to cause a sham injury. Twenty-four hours after injury, the fasting blood glucose was measured ( n=12), followed by intraperitoneal glucose tolerance test and oral glucose tolerance test; the curve of blood glucose concentration changes over time was plotted, and the area under the curve was calculated ( n=6); the blood was taken from the heart before intraperitoneal injection or gavage of glucose solution and at 30, 60, and 120 minutes after intraperitoneal injection or gavage of glucose solution for measuring the plasma insulin and glucagon like peptide-1 (GLP-1) levels using enzyme-linked immunosorbent assay (ELISA), with a sample number of 3; the ileal tissue was taken from 3 mice in each group for detecting the GLP-1 expression and apoptosis levels of intestinal L cells by immunofluorescence staining and TdT-mediated dUTP nick-end labeling staining; the pancreatic islets were collected from 6 mice in each group for glucose-stimulated insulin secretion experiments. After incubation with low glucose (2.8 mmol/L glucose) and high glucose (16.7 mmol/L glucose), the supernatant was taken and the insulin level was detected using ELISA. Thirty-six C57BL/6J male mice aged 8-10 weeks were divided into sham injury group, burn group, and burn+exendin-4 (Ex-4) group (with 12 mice in each group) according to the random number table. The mice in sham injury group and burn group were subjected to the same corresponding treatment as before. The mice in burn+Ex-4 group were injured in the same way as the burn group mice followed by treatment with GLP-1 receptor agonist Ex-4. Twenty-four hours after injury, mouse pancreatic islets were collected, the protein expressions of heavy-chain binding protein (BIP), protein kinase R-like endoplasmic reticulum kinase (PERK), phosphorylated PERK (p-PERK), eukaryotic translation initiation factor 2α (eIF2α), phosphorylated eIF2α (p-eIF2α), and CCAAT/enhancer-binding protein homologous protein (CHOP) were detected using Western blotting, and the p-PERK/PERK and p-eIF2α/eIF2α ratios were calculated ( n=3), the apoptosis rate of pancreatic islet cells was detected using flow cytometry ( n=3), the glucose stimulated insulin secretion experiment was conducted as before to detect insulin levels in the supernatant ( n=6). Results:Twenty-four hours after injury, the fasting blood glucose of mice in burn group was (7.3±1.0) mmol/L, which was significantly higher than (5.1±0.6) mmol/L in sham injury group ( t=6.36, P<0.05). Twenty-four hours after injury, in the intraperitoneal glucose tolerance test and oral glucose tolerance test, the areas under the curve of blood glucose concentration changes over time of mice in burn group were significantly larger than those in sham injury group (with t values of 4.32 and 6.03, respectively, P<0.05); compared with those in sham injury group, the plasma insulin levels of mice before intraperitoneal injection of glucose solution and the plasma GLP-1 levels of mice before intraperitoneal injection or gavage of glucose solution in burn group were significantly decreased ( P<0.05), and the plasma levels of insulin of mice at 30, 60, and 120 minutes after intraperitoneal injection or gavage of glucose solution, as well as the plasma levels of GLP-1 of mice at 30 and 60 minutes after gavage of glucose solution were significantly decreased in burn group ( P<0.05). Twenty-four hours after injury, compared with those in sham injury group, the GLP-1 expression level of intestinal L cells of mice in burn group was significantly decreased ( t=7.74, P<0.05), and the apoptosis level was significantly increased ( t=14.28, P<0.05). Twenty-four hours after injury, the insulin level in the supernatant of mice pancreatic islet incubated with high glucose in burn group was (8.5±0.4) ng/mg, which was significantly lower than (15.7±0.3) ng/mg in sham injury group ( t=18.68, P<0.05). Twenty-four hours after injury, compared with those in sham injury group, the protein expression levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, and CHOP in the pancreatic islets of mice in burn group were significantly increased ( P<0.05); compared with those in burn group, the protein expression levels of BIP, p-PERK/PERK, p-eIF2α/eIF2α, and CHOP in the pancreatic islets of mice in burn+Ex-4 group were significantly decreased ( P<0.05). Twenty-four hours after injury, the apoptosis rate of pancreatic islet cells of mice in burn group was (32.0±3.0)%, which was significantly higher than (10.3±2.5)% in sham injury group ( P<0.05); the apoptosis rate of pancreatic islet cells of mice in burn+Ex-4 group was (20.0±3.6)%, which was significantly lower than that in burn group ( P<0.05). Twenty-four hours after injury, the insulin level in the supernatant of mice pancreatic islet incubated with high glucose in burn group was significantly lower than that in sham injury group ( P<0.05), while the insulin level in the supernatant of mice pancreatic islet incubated with high glucose in burn+Ex-4 group was significantly higher than that in burn group ( P<0.05). Conclusions:After severe burns, the mice display dysfunction of the entero-insular axis, increased apoptosis of intestinal L cells, decreased synthesis and secretion of GLP-1, endoplasmic reticulum stress and increased apoptosis in pancreatic islet cells and a decrease in glucose-stimulated insulin secretion. The GLP-1 receptor agonist Ex-4 can protect the function of pancreatic islet cells of mice with severe burns, reducing the apoptosis level of pancreatic islet cells and promoting insulin secretion possibly via the alleviation of endoplasmic reticulum stress.

Correctly identifying the treatment failure in chronic tic disorders can prevent the continued use of unnecessary treatments and facilitate timely escalation to experimental or even invasive treatment.However, there is still a lack of a standard definition for the treatment failure in chronic tic disorders.Led by Professor Davide Martino from the University of Calgary in Canada, several rounds of web-based Delphi surveys were conducted to formulate expert clinicians′ consensus-based definition for treatment failure in chronic tic disorders.This consensus defines the treatment failure in chronic tic disorders from 4 aspects of behavioral and pharmacological interventions: lack of efficacy, adherence, tolerability and behavioral disorders.In addition, it further defines the failure of behavioral intervention as a whole and pharmacological intervention as a whole.This article interprets the process and key contents of the consensus, and discusses the definition of refractory tic disorders to help clinicians improve their understanding of the treatment failure in chronic tic disorders.

Tic disorder(TD), including Tourette syndrome, was first reported in 1825 and officially named in 1885.Until 1961, Haloperidol was proven to be effective in treating TD, which ushered in a new era of clinical understanding and research on TD.This paper introduces the history of research, development issues and research prospects related to TD.

Tic disorder (TD) is a neurodevelopmental disorder that starts in childhood with tics as its primary clinical manifestation.It is a group of movement disorders with unknown causes.At present, the main pathogenic genes of TD have not been identified.In this paper, TD neurotransmitter-associated susceptibility genes ( DRD2, DRD4, SLC6A4, HDC, ADRA2A), related susceptibility gene variations ( ASH1L, CELSR3, PNKD, NRXN1, CNTN6), and other susceptibility genes ( FLT3, SLITRK1) were reviewed to provide references for the precision treatment based on gene variations.

Objective:To investigate the enrollment scale and distribution of Master's Degree in Pediatrics programs in China, and to provide a reference for promoting pediatric education and disciplinary development.Methods:Data on colleges and universities authorized to award Master's Degree in Pediatrics in 2023 were collected, sorted, and analyzed for the number, structure, distribution, and enrollment scale and direction of these institutions using descriptive statistics.Results:Among the 117 clinical medicine academic master's degree programs in China, 72 enroll pediatric academic master's degree candidates, with an enrollment of 260 students. Among the 120 master's degree programs in clinical medicine, 104 enroll professional master's degree candidates, enrolling 1 195 students. Enrollment is mainly concentrated in East China, "non-double first-class" colleges and universities, medical colleges and universities with subject level B, and enrollment is carried out in the direction of secondary disciplines.Conclusions:The number of colleges and universities authorized to award Master's Degree in Pediatrics was small, and the distribution of these colleges and universities was unbalanced. The enrollment scale was small and the orientation of Professional Master's Degree was not reasonable. Some colleges and universities were authorized to award Master's Degree in Pediatrics, but did not enroll any students. It is suggested to increase the number of colleges and universities authorized to award Master's Degree in Pediatrics and strengthen the staffing of pediatric departments. The aim is to expand the enrollment scale of candidates for Master's Degree in Pediatrics, improving the differential training of candidates for Academic Master's Degree and Professional Master's Degree, and attach importance to the construction of pediatrics.
