Objective To address the current blind spots in quality control and the risk of data distortion in radiological health technical service institutions, overcome the limitations of low efficiency and insufficient anomaly identification in manual verification, establish an automatic anomaly early warning mechanism based on AI algorithms, provide accurate clues for health supervision and law enforcement, and significantly enhance the efficiency of industry supervision. Methods On-site inspection data were collected via photographic imaging. Advanced image processing and object detection algorithms were employed to automatically extract and analyze key information from the images. Through data analysis, the system was used to calculate and assess the inspection results. A dynamic early warning engine was developed to automatically trigger alerts upon detection of deviations from standard thresholds or regulatory violations in radiological health technical services. These alerts were delivered through a regulatory information system. Results Following AI model training, the accuracy of the image processing and object detection algorithms reached 99% and the early warning accuracy reached 93%. Compared with the traditional supervision mode, the efficiency of anomaly detection was improved and the average response time was shortened. Conclusion The full-process supervision information system constructed in this study has realized the triple mechanism of pre-event standardization, in-event monitoring, and post-event traceability for radiological health technical services. In particular, the system has established a four-level quality control chain of “institutional self-inspection, intelligent recheck, expert judgment, and administrative action”, providing a technological innovation path for ensuring the radiation protection and safety of medical staff, patients, and the public.

Chemotherapy is an important treatment for tumors， but most patients experience varying degrees of chemotherapy- induced myelosuppression. Four properties theory of traditional Chinese medicine （TCM） has unique advantages in improving chemotherapy-induced myelosuppression. The monomers from TCM with different properties and flavors， such as cold-natured （e.g. Scutellaria baicalensis， Rhus chinensis）， cool-natured （e.g. Ligustrum lucidum， Ophiopogon japonicus）， warm-natured （e.g. Panax ginseng， Epimedium brevicornu， Curcuma longa， Angelica sinensis）， hot-natured （e.g. Cinnamomum cassia， Aconitum carmichaeli）， and neutral-natured （e. g. donkey-hide gelatin， Lycium barbarum， Rhodiola rosea， fungi）， can exert anti- myelosuppressive effects by reducing damage to hematopoietic stem/progenitor cells， improving the bone marrow hematopoietic microenvironment， inhibiting the oxidative stress response， regulating signaling pathways， so as to ultimately repaire inflammatory damage and improve hematopoietic function， thereby playing an anti-myelosuppressive role.

Dental caries, a chronic disease characterized by tooth decay, occupies the second position in terms of disease burden and is primarily caused by cariogenic bacteria, especially Streptococcus mutans, because of its acidogenic, aciduric, and biofilm-forming capabilities. Developing novel targeted anti-virulence agents is always a focal point in caries control to overcome the limitations of conventional anti-virulence agents. The current study represents an up-to-date review of in silico approaches of drug design against dental caries, which have emerged more and more powerful complementary to biochemical attempts. Firstly, we categorize the in silico approaches into computer-aided drug design (CADD) and AI-assisted drug design (AIDD) and highlight the specific methods and models they contain respectively. Subsequently, we detail the design of anti-virulence drugs targeting single or multiple cariogenic virulence targets of S. mutans, such as glucosyltransferases (Gtfs), antigen I/II (AgI/II), sortase A (SrtA), the VicRK signal transduction system and superoxide dismutases (SODs). Finally, we outline the current opportunities and challenges encountered in this field to aid future endeavors and applications of CADD and AIDD in anti-virulence drug design.

Objective: To investigate the effects of “Three Methods and Three Acupoints” (TMTP) Tuina therapy on spinal microcirculation in sciatic nerve injury (SNI). Methods: Thirty-six Sprague–Dawley rats were randomly assigned to four groups: normal, sham operation, model, and TMTP Tuina. Successful model induction was confirmed by observable hind limb lameness. After 20 sessions, hind limb grip strength and motor nerve conduction velocity (MNCV) were measured at baseline and following the 10th and 20th intervention. CD31 and α-SMA in the ventral horn of SNI model rats were detected using immunofluorescence. Motor neurons in the ventral horn were detected by Nissl staining. PTEN levels in the ventral horn were measured by ELISA, and PI3K, Akt, BDNF, VEGF, and HIF-1α expression was determined by RT-PCR. Spinal cord microcirculation was evaluated by western blotting analysis of the levels of Akt, p-Akt, BDNF, and VEGF. Results: Hind limb grip strength and MNCV significantly improved in the TMTP Tuina group compared to the model group (both P < .001). Morphology of ventral horn motor neurons in the TMTP Tuina group improved compared to the model group, with increased expressions of α-SMA (P = .002) and CD31 (P = .006). Western blot analysis indicated increased expression of VEGF (P = .005), p-Akt (P < .001), and BDNF (P = .008) in the ventral horn following Tuina treatment. RT-PCR analysis revealed increased expression of PI3K, Akt, BDNF, VEGF and HIF-1α (all P < .05). In contrast, expression of PTEN decreased compared to the model group (P < .001). Conclusion TMTP Tuina therapy may restore motor function in rats, enhance ventral horn motor neuron morphology, and promote angiogenesis and vascular smooth muscle proliferation. The mechanism may involve the activation of the PI3K/Akt signaling pathway.

Diabetic peripheral neuropathy（DPN） is a neurodegenerative disease of diabetes mellitus involving peripheral nervous system damage， which is characterized by axonal degenerative necrosis， Schwann cell apoptosis and demyelination of nerve myelin sheath as the main pathological features， this disease is highly prevalent and is a major cause of disability in diabetic patients. Currently， the pathogenesis of DPN may be related to oxidative stress， inflammatory response， metabolic abnormality， and microcirculation disorder. The treatment of DPN in modern medicine mainly starts from controlling blood glucose， nourishing nerves and improving microcirculation， which can only alleviate the clinical symptoms of patients， and it is difficult to fundamentally improve the pathological damage of peripheral nerves. Mitochondrial quality control refers to the physiological mechanisms that can maintain the morphology and functional homeostasis of mitochondria， including mitochondrial biogenesis， mitochondrial dynamics， mitochondrial oxidative stress and mitochondrial autophagy， and abnormal changes of which may cause damage to peripheral nerves. After reviewing the literature， it was found that traditional Chinese medicine（TCM） can improve the low level of mitochondrial biogenesis in DPN， maintain the balance of mitochondrial dynamics， inhibit mitochondrial oxidative stress and mitochondrial autophagy， and delay apoptosis of Schwann cells and neural axon damage， which has obvious effects on the treatment of DPN. With the deepening of research， mitochondrial quality control may become one of the potential targets for the research of new anti-DPN drugs， therefore， this paper summarized the research progress of TCM in treating DPN based on four aspects of mitochondrial quality control， with the aim of providing a theoretical research basis for the discovery of new drugs.

Sha （痧） is an acute infectious disease characterised by the appearance of rashes on the skin， caused by exposure to epidemic toxin and pestilent qi. Sha Zhang Yu Heng （《痧胀玉衡》） discussed the treatment principles and methods， and listed collateral bloodletting as one of the main treatments. Through organizing the articles and proved cases， we found that the author believes Sha （痧） is caused by epidemic pathogen， belonging to heat toxin with rapid changes， so timely treatment for qi and blood simultaneously could achieve the effect of transforming qi into defensive qi. Sha Zhang Yu Heng focuses on patient's position during treatmet， the material of the needle， the site of treatment， the quantum of stimulation and the operation of the contraindications and other essentials. According to the depth of the disease location， use traditional Chinese herbal medicine， scraping together to identify the root of the disease. In addition， diet suggestions for the prevention of the recrudescence of disease are also described in detail.

Objective To study the quality comparability of human coagulation factor Ⅷ(FⅧ)produced before and after the change of factory site.Methods A comparative study was carried out on quality quantitative indexes,related im-purities and stability data of FⅧ produced before and after the change of factory site.Results The FⅧ quantitative quality before and after the change of factory site all met the quality standard,and the related impurities including aluminum resi-due,tributyl phosphate residue,polysorbate 80 residue and PEG residue all met the quality standard.Other impurities in-cluding human fibrinogen,fibronectin,plasminogen,IgA,IgM and IgG were extremely low in content and equivalent in quality.The content of VWF(von Willebrand factor)had no obvious change before and after the change of factory site,but was significantly higher than that of other domestic manufacturers'commercial products.The results of accelerated stability and long-term stability tests showed that the titer of FⅧ fluctuated within the methodological error range,and the results all met the quality standard.Conclusion The change of factory site of FⅧ has no effect on the quality.
