The welfare and ethics of laboratory animals are the ethical principles and behavioral norms that need to be followed in conducting animal-based scientific research, breeding and managing laboratory animals, and supervising and regulating such activities. The level of protection of laboratory animal welfare and ethics is closely related to the development of science and technology, which has become a widely recognized international consensus. At present, Guangdong Province is accelerating the construction of a high-level science and technology innovation province and the Guangdong-Hong Kong-Macao Greater Bay Area International Science and Technology Innovation Center. Guangdong Province should rely on its advanced governance capacity in the field of laboratory animal science and technology ethics to promote the high-quality development of its laboratory animal science and technology sector. Based on the management laws, regulations, and institutional mechanisms of laboratory animals in China, this paper explores the optimization of the laboratory animal science and technology ethics governance system, which includes the institutional guarantees, responsibility systems, ethical review and supervision mechanisms, and education and outreach. Through methods such as literature research, questionnaire surveys, and interview investigations, an empirical study of the laboratory animal science and technology ethics governance system in Guangdong Province has been conducted. Analysis of literature and research results shows that Guangdong Province has basically established a laboratory animal management system, collaboration mechanism, supervision mechanism, and education and training system that meet the current requirements of the laboratory animal science and technology ethics governance system in China. However, there are still problems such as an incomplete laboratory animal science and technology ethics supervision mechanism, an underdeveloped operation mechanism of review institutions, insufficient attention paid by laboratory animal units to the ethical review of animal experiments, inconsistent ethical review standards, and a lack of professional ethical education and training for ethics review personnel. Therefore, optimization measures such as improving the laboratory animal science and technology ethics review system, strengthening supervision and inspection, further strengthening the accountability of responsible entities, formulating review norms, and enhancing hierarchical and classified education and training are proposed, to provide a theoretical basis for promoting the normalized and long-term governance of laboratory animal science and technology ethics in Guangdong Province.

Objective:To evaluate the clinical efficacy of returning, squeezing, patting and pulling orthopaedic manipulation combined with pelvic fabric tape fixation for the treatment of postpartum pubic symphysis separation.Methods:The clinical data of 80 patients with postpartum pubic symphysis separation from June 2015 to March 2019 were retrospectively analyzed, and all of them were given orthopaedic manipulative therapy using return squeezing and patting and pulling, once a week, for a total of 3 times. After the manipulative treatment, the patients were instructed to brake the pelvic fixation straps for not less than 8 h per day, and digital X-ray (DR) pelvic radiographs or ultrasound tests were performed before and after the treatment to measure the distance between the pubic symphysis. VAS scale was used to assess the degree of pain, and the Oswestry dysfunction index (ODI) was used to assess the degree of dysfunction. The clinical efficacy was evaluated.Results:After treatment of 80 patients, 6 showed significant improvement, 69 showed improvement, and 5 showed no improvement, with a total effective rate of 93.8%. Compared with before group, the inter-pubic symphysis distance [(15.09±3.10) mm, (12.01±4.36) mm, (9.64±0.30) mm, (8.18±1.56) mm vs. (19.35±1.08) mm, F=254.64] were significantly smaller at 1 week, 2 weeks, 3 weeks, and 1 month ( P<0.001); VAS scores (2.90±1.24, 1.29±0.88, 0.84±0.43, 0.56±0.32 vs. 6.11±2.93, F=122.60) were significantly lower than before treatment ( P<0.001); ODI (28.09±4.30, 22.01±4.95, 20.64±0.41, 14.18±1.36 vs. 45.43±4.01, F=734.17) were significantly reduced ( P<0.001). Conclusion:Returning, squeezing, patting and pulling orthopaedic manipulation combined with pelvic fabric tape fixation can quickly restore the separation distance of the pubic symphysis, reduce local pain and improve lumbosacral function.

The present case report described a patient with paroxysmal atrial fibrillation who received pulsed-filed ablation guided by intracardiac echocardiography and 3-dimentional mapping system.All four pulmonary veins were isolated in the procedure,good clinical results and acute safety profile were achieved.The present case reveals the safety and feasibility of the technique for the treatment of paroxysmal atrial fibrillation.

IgA nephropathy is a common primary glomerular disease,and autophagy plays an important role in maintaining the homeostasis of the internal environment.Dysfunction of cellular autophagy can affect the occurrence and development of IgA nephropathy.This article focused on the molecular mechanism of TCM regulating autophagy in renal intrinsic cells,and found that TCM extracts and formulas mainly regulate autophagy through PI3K/Akt/mTOR,TLR4/NF-κB,MAPK,Nrf2/HO-1,NLRP3 and other signaling pathways.Furthermore,it could intervene in pathological damage such as renal fibrosis,inflammation,and oxidative stress,delaying the progression of IgA nephropathy,in order to provide reference for the clinical treatment and new drug development of IgA nephropathy.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

China has entered a stage of deep aging. The expanding aging population and subsequently an aging labor force pose significant challenges to China’s social and economic development. European Union (EU) countries have entered the aging phase earlier and to a greater extent. To address the labor shortage and the rising dependency ratio, the EU has implemented a series of policies and measures, including raising retirement age, promoting flexible retirement, enhancing work flexibility, improving welfare for elderly workers, creating age-friendly environments, focusing on occupational health, strengthening knowledge and skills training, and leveraging digital technologies in the workplace. These measures aim to prevent premature exit of elderly workers, better balance their work and life needs, improve occupational health and skills, and enhance overall work efficiency of companies. This review discussed the experience and lessons learned from the EU countries in addressing the aging workforce from the perspectives of occupational health and occupational skills development, aiming to provide rational suggestions to assist China in better adapting the challenges of aging workforce after steadily and orderly advancing the gradual reform of the statutory retirement age, thereby improving the efficiency of the overall workforce and the stability of the labor market, driving the talent dividend of highly educated and skilled middle-aged and elderly employees, and ultimately promoting sustained economic and social development.

In patients with acute ischemic stroke, there is a wide variation in the composition of blood clots that block the blood vessels. Some imaging features are associated with the components of the clot, such as thrombus permeability, which is related to higher red blood cell density and lower fibrinogen density. The different components and mechanical properties of the clot may have an impact on treatment effectiveness and risk. Therefore, this article aims to summarize the correlation between thrombus permeability and biological, imaging characteristics, and explore the clinical significance of thrombus permeability in the treatment of patients with acute ischemic stroke, providing reference and assistance for neurologists.

Breast cancer （BC） ranks first in the incidence rate of female malignant tumor， the notable features of which include high invasive behavior， high malignant degree and poor prognosis. Resveratrol， a plant antioxidant， has been identified as a potential therapeutic agent for the occurrence and progress of BC. This article explores the mechanism of resveratrol intervention in BC by evaluating several in vitro and in vivo studies. It was found that resveratrol can weaken the proliferation and survival ability of BC cells， suppress their growth， metastasis， and invasion， and reverse their resistance to adriamycin by promoting cell apoptosis， regulating autophagy， inhibiting glycolysis and regulating the tumor microenvironment， expressions of matrix metalloproteinases， epithelial-mesenchymal transition and drug-resistant proteins， etc. The limited number of clinical trial studies on resveratrol， mainly focusing on prevention effect of it on breast cancer， may be one of the reasons that affect the comprehensive evaluation of the anti-cancer efficacy of resveratrol.
