Objective To address the safety challenges arising from the rapid development of nuclear energy and technology, assess the current status of health emergency response capabilities in nuclear radiation emergencies, and promote capacity enhancement. Methods A preliminary evaluation system for health emergency response capability in nuclear radiation emergencies was developed based on a literature review. Two rounds of Delphi expert consultation (n = 20) were conducted, and the analytic hierarchy process was employed to establish judgment matrices for assigning indicator weights. Results The finalized system included six primary indicators (radiation protection capability, triage capability, decontamination and evacuation capability, medical treatment capability, radiation detection capability, and radiation dose estimation capability), along with 29 secondary indicators, such as capability for setting up emergency zones, capability for protecting personnel from internal and external contamination, on-site first aid capability, and personal dose monitoring capability. The expert response rate was 0.95, and the expert authority coefficient reached 0.80. The Kendall’s coefficient of concordance was W = 0.288 (P<0.01) for the first round of expert consultation and W = 0.308 (P<0.01) for the second round. Both rounds demonstrated high agreement among experts, and the consultation questionnaires passed reliability and validity tests. Conclusion By integrating qualitative analysis and quantitative calculation, this study developed a scientifically sound and operationally feasible evaluation system. This system will help identify gaps in health emergency response capabilities and provide scientific guidance and a decision-making basis for optimizing emergency plans and improving the level of health emergency response in nuclear radiation emergencies.

ObjectiveTo investigate whether the effect of Taohong Siwutang on cerebral ischemia-reperfusion （CIRI） injury in rats is related to the regulation of astrocyte polarization and explore the related mechanism. MethodsEighty-four male SD rats were randomly assigned to the following groups： A sham operation group， a model group， Taohong Siwutang treatment groups （low dose， medium dose， and high dose）， ligustrazine phosphate tablet （LPT） group， and AG490 group. All groups， except for the sham operation group， underwent middle cerebral artery occlusion/reperfusion （MCAO/R） modeling and were treated for seven days. The neurological impairment was evaluated using the Longa score. The volume of cerebral infarction was assessed through 2，3，5-triphenyltetrazolium chloride （TTC） staining. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot analyses were performed to analyze the mRNA and protein expression levels of cortical complement 3 （C3）， S100 calcium-binding protein A10 （S100A10）， Janus kinase 2 （JAK2）， and signal transducer and activator of transcription 3 （STAT3）. Additionally， protein expression levels of vascular endothelial growth factor-A （VEGF-A） were assessed， and the mRNA expression levels of inflammatory factors， including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α）， were evaluated. Glial fibrillary acidic protein （GFAP） and C3， S100A10 and Co-localization was detected via immunofluorescence double staining. Lastly， VEGF expression levels were measured using enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham operation group， the model group showed a significant increase in cerebral infarction volume and neurological impairment （P<0.01）. C3 protein levels were elevated， while S100A10 levels were decreased. Pathway-related markers were significantly upregulated （P<0.05， P<0.01）， and VEGF-A protein levels were significantly reduced （P<0.01）. The mRNA expression of inflammatory factors was significantly upregulated （P<0.01）. Co-localization analysis showed significantly increased GFAP and C3 fluorescence intensity （P<0.01） and greatly decreased GFAP and S100A10 fluorescence intensity （P<0.01）. Additionally， VEGF content was significantly elevated （P<0.01）. Compared with the model group， medium- and high-dose Taohong Siwutang and LPT groups exhibited a significant reduction in cerebral infarction volume and neurological impairment （P<0.01）. Groups treated with low， medium， and high doses of Taohong Siwutang and LPT group exhibited a decrease in C3 protein expression levels and an increase in S100A10 expression levels （P<0.01）. In the high-dose Taohong Siwutang and AG490 groups， both protein and mRNA expression of C3 and pathway-related markers were significantly downregulated （P<0.05， P<0.01）， while S100A10 expression and VEGF-A protein levels were significantly increased （P<0.01）. Additionally， the mRNA expression levels of inflammatory factors were significantly reduced （P<0.01）. The co-localization fluorescence intensity of GFAP and C3 significantly decreased （P<0.01）， while that of GFAP and S100A10 greatly increased （P<0.01）. Furthermore， VEGF content exhibited a marked elevation （P<0.01）. ConclusionTaohong Siwutang exerts a protective effect in rats with cerebral CIRI injury. The underlying mechanism is associated with the downregulation of the JAK2/STAT3 signaling pathway， promotion of A2-type astrocyte polarization， reduction of inflammatory factor release， and enhancement of VEGF production.

Objective To investigate the current level of public awareness regarding nuclear emergency evacuation around a nuclear power plant, analyze the influencing factors, and propose suggestions and countermeasures based on the results. Methods In July 2024, according to the survey protocol and questionnaire developed by the National Institute for Radiological Protection, Chinese Center for Disease Control and Prevention, a field-based centralized online questionnaire was administered. A total of 854 residents living near the nuclear power plant were included as survey participants. An analysis of variance was used to compare the impact of different factors on the public knowledge of nuclear radiation and awareness of nuclear emergency evacuation, while the chi-square test was employed to compare differences between groups. Results A total of 854 questionnaires were collected in this study. The survey revealed that the levels of public knowledge about nuclear radiation and awareness of nuclear emergency evacuation around the power plant were relatively low, with average objective awareness rates of 51% and 47%, respectively. In terms of age, the 30-45 years old group had the highest average score, while the group aged 60 and above had the lowest. Regarding education level, the group with primary school education or below had the lowest average score, whereas those with junior college or undergraduate education scored the highest. The internet (73.7%) was the primary source of emergency information for the public, followed by television (61.7%). The majority of the public (85.0%) expressed trust in the government during evacuation and were willing to follow governmental evacuation arrangements. The main reason for this willingness was the belief that the government could provide sufficient emergency supplies. Conclusion The surveyed population exhibited low levels of knowledge regarding nuclear radiation and awareness of nuclear emergency evacuation, with generally low awareness rates. Awareness levels were influenced by factors such as sex, age, educational background, and distance from the nuclear power plant. To enhance public awareness, it is necessary to strengthen science communication related to nuclear radiation and public protective actions in nuclear emergencies. Targeted dissemination strategies with high communication effectiveness, accessibility, and public acceptance should be adopted to gradually enhance public awareness of nuclear radiation and nuclear emergency protective actions.

In this paper， by referring to ancient and modern literature， the textual research of Kochiae Fructus has been conducted to clarify the name， origin， distribution of production areas， quality specification， taste and efficacy， harvesting time， processing and compatibility taboo， so as to provide reference and basis for the development and utilization of related famous classical formulas. According to the investigation， it can be seen that Difuzi was first published in Sheng Nong's Herbal Classic， and has been used as the official name throughout history. It is also known by other names such as Dimai， Dikui， and Luozhou. The mainstream source of Difuzi in materia medica throughout history is the dried ripe fruit of Kochia scoparia， which is consistent throughout history. In the Han dynasty， it was recorded that Kochiae Fructus was produced in Jingzhou（Hubei province）， while modern literature records its distribution throughout the country， so it does not have obvious geoherbalism. The harvesting period of Kochiae Fructus is mostly in the late autumn， and the quality is best when it is full， gray green in color， and no impurities. There are two processing methods for its origin：from the Southern and Northern dynasties to the Ming dynasty， it was dried in the shade， and after the founding of the People's Republic of China， it was dried in the sun. There are few records about the processing of Kochiae Fructus， and its clinical application is mostly based on raw products as medicine. The seedlings are harvested in February of the lunar calendar， and the leaves are taken in April and May， processing in the place of origin is shade drying， the processing methods include burning ash and frying frost， pounding juice and wine soaking. For internal use， it is mostly decocted or mashed， while for external use， it is mostly washed with decoction or taken in a soup bath. Throughout history， it has been recorded that Kochiae Fructus is bitter and cold， and is mainly used for treating bladder fever. After the founding of the People's Republic of China， most of the literature classified it as damp-clearing medicine. Since the 1985 edition of Chinese Pharmacopoeia， it has been recorded that Kochiae Fructus has a pungent and bitter taste， and a cold nature. Returning to the kidney and bladder meridians with functions of clearing heat and dampness， dispelling wind and relieving itching. The clinical contraindications are mainly prohibited for those with deficiency and no dampness and heat. Throughout history， it has been recorded that the taste of the seedlings and leaves is bitter and cold for treatment of dysentery. Since modern times， it has been used to regulate the liver， spleen and large intestine meridians， with functions such as clearing heat and detoxifying， and diuresis. Based on the textual research， it is recommended to use the dried ripe fruit of K. scoparia when developing the famous classical formulas containing Kochiae Fructus， and processing shall be carried out according to the original processing requirements. If the original formula does not specify the processing requirements， the raw products is taken into medicine.

In this paper， by referring to ancient and modern literature， the textual research of Cnidii Fructus has been conducted to clarify the name， origin， distribution of production areas， quality specification， nature and flavour， efficacy， harvesting and processing， compatibility taboo and others， so as to provide reference and basis for the development and utilization of the relevant famous classical formulas. After textual research， it can be verified that Cnidii Fructus was first published in Sheng Nong's Herbal Classic， the materia medica of all dynasties was named Shechuangzi， and there are also aliases such as Shesu， Shemi， and Qiangmi. The main source for generations was the dried ripe fruit of Cnidium monnieri， and ancient and modern consistent. From the Eastern Han dynasty to Tang dynasty， the origin of Cnidii Fructus was Zibo， Shandong province. During the Five dynasties， it expanded to Yangzhou in Jiangsu province and Xiangyang in Hubei province， the Song dynasty added Shangqiu in Henan province， and it was considered that Yangzhou， Xiangyang and Shangqiu were its genuine producing areas. It was more widely distributed in Ming and Qing dynasties. After the founding of the People's Republic of China， the origin is clearly distributed throughout the country. For its quality evaluation， generally full grain， gray yellow color， strong aroma is the best. The harvesting period in the past dynasties was mostly the fifth lunar month， and the fruit was collected to remove impurities and dry. The mainstream processing in producing area of the past dynasties was net selection of raw products， mixing and steaming with the juice of Rehmanniae Radix and stir-frying were the mainstream processing methods in the past， there were also stir-frying with honey， stir-frying with salt and rice wine， immersing and steaming with rice wine and other methods. In recent times， it has been used in raw products as medicine. Sheng Nong's Herbal Classic recorded Cnidii Fructus was bitter， Supplementary Records of Famous Physicians recorded its acrid for the first time. It was recorded in the Ming dynasty that its nature was warm， acted on the kidney meridian， and had small toxicity. After the founding of the People's Republic of China， most of the literature classified it as a medicine to attack poison， kill insects and relieve itching with the functions of dispelling pathogenic wind and removing dampness， destroying parasites and elieving itching， warming kidney and activating Yang. Clinical contraindications are mainly contraindicated for people with damp-heat from the lower-jiao or kidney heat. Based on the textual research， it is suggested that when developing the famous classical formulas containing Cnidii Fructus， the source shall be the dried ripe fruit of C. monnieri， and then it shall be processed according to the original formulas. If there is no requirement for processing in the formulas， the raw products can be taken into medicine.

As a key member of the insulin-like growth factor family， insulin-like growth factor-‍Ⅰ （IGF-‍Ⅰ） is mainly synthesized in the liver and is widely distributed in the human body， and it is involved in the physiological processes such as cell proliferation， differentiation， metabolism， and apoptosis. Studies have shown that the level of IGF-‍Ⅰ is negatively correlated with the severity of liver cirrhosis， and IGF-‍Ⅰ mainly affects the progression of liver cirrhosis by inhibiting liver fibrosis， promoting DNA damage repair， and regulating lipid metabolism. Monitoring of IGF-‍Ⅰ level is expected to provide an evaluation indicator for improving the prognosis of patients with liver cirrhosis， and stimulating the action pathway of IGF-‍Ⅰ or regulating its expression level may become a new method for the treatment of liver cirrhosis. This article reviews the research advances in IGF-‍Ⅰ in liver cirrhosis， in order to provide new ideas for the diagnosis and treatment of liver cirrhosis.
