ObjectiveThe development trend and knowledge structure of the research on human use experience （HUE） of traditional Chinese medicine （TCM） were systematically reviewed， and the core challenges and future directions were identified. This study aims to provide reference for the construction of a scientific and feasible research and development framework and evidence transformation system. MethodsLiterature related to "human use experience" published from January 1， 2019 to July 31， 2025 was retrieved from the China National Knowledge Infrastructure （CNKI）， Wanfang， China Science and Technology Journal Database （VIP）， and PubMed databases. Bibliometric visualization was conducted using Excel， VOSviewer， and CiteSpace， followed by in-depth reading and thematic summarization of core literature. ResultsA total of 181 papers were included for bibliometric analysis， with 45 articles used for in-depth thematic mining. The analysis showed that the number of publications on HUE research has increased in a stepwise manner over the past five years. Yang Zhongqi （24 times） was the core of the author network， the journal with the highest number of publications was China Journal of Chinese Materia Medica， the institutions publishing the most articles were mainly research institutions， regulatory agencies， hospitals， and universities， high-frequency keywords included "new TCM drugs"， "real-world studies"， and "clinical comprehensive evaluation"， keyword clustering analysis formed three major clusters： Policy orientation， application fields， and methodological approaches. Thematic analysis reveals that HUE-based evaluation should be integrated throughout the research and development process， encompassing three dimensions： TCM theory， clinical value， and pharmaceutical fundamentals， with toxic herbs and compatibility contraindications being key foci. Data collection primarily relies on empirical data， while real-world data constitute the primary source for clinical research， with efficacy and safety as the shared core. Data management emphasizes quality control and statistical analysis； however， the management of bias and confounding remains a critical bottleneck in evidence transformation. In practice， HUE-based approaches have successfully supported the registration and evaluation of multiple categories of new TCM drugs. ConclusionThe research on HUE of TCM has formed a policy-driven pattern characterized by， rapid development and close link with regulatory practice. A technical framework covering the whole chain of research and development has been constructed with clinical value as the core， which provides methodological basis and strategy reference for the scientific transformation of HUE of TCM from "experience" to "evidence".

The exploration and pilot studies of applying blockchain to drug supply chain show great potential in promoting information sharing, collaboration competence among the actors, regulatory efficiency, and etc. In the future, with the help of blockchain, the optimization of the entire supply chain for orphan drugs is expected to be realized. However, there is no such exploration in China at present. This paper systematically sorts out the whole process of supply chain for orphan drugs and the existing problems of the chain. The article concludes that at present, blockchain is mainly used in the " circulation" and " use" of the drug supply chain. It helps to improve the traceability of drugs, to cope with the problem of counterfeit drugs, to enable actors of the drug supply chain to form a collaborative network in optimizing resource allocation, and to improve the operation and supervision efficiency of the supply chain. In the future, the application faces challenges such as high costs in system conversion, lack of personnel awareness, and incomplete supporting systems. Based on the three dimensions of technology, practice, and research, this paper also looks into the future and suggests for the future use of blockchain in the supply chain of orphan drugs by constructing a practice model, the so called DI-GIVE (Digital, Intelligence, Government′s supervision, Innovation, Views of variety, Evaluation-based) hoping to innovate the supply chain of orphan drugs and to ensure the drug use for the patients with rare diseases in China.

ObjectiveTo investigate the effect of circSLC8A1_005 on the fibrotic phenotype of cardiac fibroblasts and the potential mechanism involved. MethodsThe effect of adenovirus-mediated overexpression of circSLC8A1_005 on the expression of fibrosis-related genes， collagen type I alpha 1 chain （Col1a1）， collagen type Ⅲ alpha 1 chain （Col3a1） and smooth muscle actin alpha 2 （Acta2）， in mouse cardiac fibroblasts （mCFs） were detected. The proliferation and migration activities of mCFs were detected by EdU and wound-healing assay， respectively. Dual luciferase reporter gene assay was performed to detect the activity of potential internal ribozyme entry site （IRES） in circSLC8A1_005. CircSLC8A1_005-translated protein， SLC8A1-605aa， and its intracellular distribution was identified by Western blot assay. The effect of SLC8A1-605aa protein on transcription activity of Sod2 gene was detected by the dual luciferase reporter gene assay. RNA binding protein immunoprecipitation （RIP） was utilized to verify the interaction between SLC8A1-605aa and superoxide dismutase 2 （Sod2） mRNA. Actinomycin D treatment was used to detect the effect of SLC8A1-605aa on Sod2 mRNA stability in mCFs. ResultsAn efficient adenovirus-mediated overexpression of circSLC8A1_005 was achieved in mCFs. The enforced expression of circSLC8A1_005 suppressed proliferation and migration of mCFs， and inhibited the expression of fibrosis-related genes in mCFs. The dual luciferase reporter gene assay revealed the activities of 2 IRES in circSLC8A1_005. Results of Western blot assay showed that circSLC8A1_005 could translate protein SLC8A1-605aa with the prospected molecular weight of 70 ku， which is predominantly distributed in the nucleus. Overexpression of the circSLC8A1_005 and SLC8A1-605aa could consistently inhibit the fibrotic phenotype of mCFs. SLC8A1-605aa could up-regulate superoxide dismutase 2 （Sod2） expression， but not at the transcriptional level. RIP assay indicated that SLC8A1-605aa could specifically interact with Sod2 mRNA， and the results of actinomycin D assay showed that SLC8A1-605aa could enhance the stability of Sod2 mRNA in mCFs. ConclusionCircSLC8A1_005 inhibits the fibrotic phenotype of cardiac fibroblasts via translating SLC8A1-605aa protein， and SLC8A1-605aa may be a potential target for the treatment of myocardial fibrosis.

In the context of the prevention and control for coronavirus disease (COVID), public health emergency governance has been incorporated into an important part of the national governance system, and the "combination of peacetime and wartime" has become an important principle of public health emergency governance. Based on the experience of public health emergency management in large cities and the theory of collaborative governance, this study analyzed the problems and obstacles of general hospitals in coping with emerging respiratory infectious diseases. It is proposed to select general hospitals above tertiary level in the region to build peacetime and wartime combined emergency hospital, establish standardized conversion procedures and strengthen the construction of key elements of integrated emergency hospitals, so as to provide new ideas for the construction of emergency medical system "combination of peacetime and wartime" mechanism and improve the "combination of civilian and combat" public health emergency governance system.

ObjectiveTo observe the clinical efficacy of Danzhi Jiangtang capsules with the functions of replenishing Qi， nourishing Yin， and dredging collaterals on patients with type 2 diabetes mellitus （T2DM） combined with lower-extremity macroangiopathy and serum levels of homocysteine （Hcy） and cystatin C （Cys C）. MethodA total of 80 eligible patients who were treated in the department of endocrinology of the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2017 to December 2019 were randomized into the treatment group （40 cases） and control group （40 cases）. Both groups received the basic therapies for diabetes and Danzhi Jiangtang capsules （oral） was added to the treatment group. The levels of glycosylated hemoglobin A1c （HbA1c）， fasting plasma glucose （FPG）， 2-hour postprandial glucose （2 hPG）， fasting C-peptide （C-P）， and 2-hour postprandial C-peptide （2 hC-P）， triglycerides （TG）， total cholesterol （TC）， high density lipoprotein cholesterol （HDL-C）， and low density lipoprotein cholesterol （LDL-C） and serum levels of Hcy and Cys C were measured and the traditional Chinese medicine（TCM） syndrome scores were calculated before and after treatment in the two groups. ResultAfter 12 weeks of treatment， levels of HbA1c， FPG， and 2 hPG were lower than those before treatment in the two groups （P<0.05）. Levels of C-P （P<0.05） and 2 hC-P were higher than those before treatment in the two groups. After treatment， levels of HbA1c， FPG， and 2 hPG in the treatment group were lower than those in the control group （P<0.05）， while levels of C-P and 2 hC-P showed no significant difference between two groups. After treatment， the levels of TG， TC， and LDL-C were lower than those before treatment （P<0.05） and HDL-C level was higher than that before treatment （P<0.05） in both groups. After treatment， levels of TG and LDL-C in the treatment group were lower than those in the control group （P<0.05）， and levels of TC and HDL-C demonstrated no significant difference between two groups. After the treatment， the TCM syndrome score was lower than that before the treatment in both groups （P<0.05） and lower in the treatment group than in the control group （P<0.05）. The overall effective rate of the treatment group was higher than that of the control group （χ^２=7.585， P<0.05）. The levels of Cys C and Hcy were lower than those before treatment in the two groups （P<0.05） and lower in the treatment group than in the control group （P<0.05）. Doppler echocardiography of the lower limbs showed no obvious improvement in the control group after treatment. However， for the treatment group， slight decrease in intima-media thickness of the lower limb arteries and a slight reduction in the plaque area were observed， but the difference was not statistically significant. ConclusionDanzhi Jiangtang capsules has definite therapeutic effect on T2DM combined with lower-extremity macroangiopathy， which can improve glucolipid metabolism and reduce serum levels of Hcy and Cys C. This study can serve a reference for the prevention and treatment of T2DM combined with macroangiopathy.

Radiotherapy is the most common treatment for nasopharyngeal carcinoma, and the radiotherapy technique is essential for the prognosis of nasopharyngeal carcinoma. Due to the complexity of the structure of the intensity-modulated device and the accuracy of the clinical requirements of radiotherapy, it is inevitable that higher requirements will be imposed on the process of intensity-modulated radiotherapy. Currently, gaps exist in the radiotherapy equipment and personnel qualification among radiotherapy units, and thus the homogenization in the radiotherapy remains to be strengthened in China. With the application of radiotherapy information management system, digital medicine and artificial intelligence technologies in the field of radiotherapy, the original process fails to meet the application needs of the new precise radiotherapy technology. Therefore, this process is designed based on the existing radiotherapy procedures for nasopharyngeal carcinoma in combination with the latest developments in the field of radiotherapy, aiming to establish a novel standard process recommendation, ensuring the standardization and homogenization of radiotherapy and achieve the individualized intensity-modulated radiotherapy for nasopharyngeal carcinoma patients.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic is a global public health crisis, which elicits psychological problems in different population This study is to investigate the impact of COVID-19 on mental health in the front-line staff. METHODS: Patient Health Questionnare-9 (PHQ-9), Self-Rating Anxiety Scale (SAS), and Fatigue Self-assessment Scale (FSAS) were used to assess the depression, anxiety, and fatigue in front-line staff. RESULTS: The detection rates of depression, anxiety, and fatigue were 49.1%, 21.8%, and 76.0% among the front-line staff. The rates of depression, anxiety, and fatigue in community workers were higher than those in medical workers and other occupational staff (<0.01). The PHQ-9 of front-line staffs was negatively correlated with age, family income, family members' support, satisfaction of service objects, and sleep quality (all <0.01), while positively correlated with education level, fatigue, fear of pneumonia, and the duration of daily attention to the COVID-19 (all <0.01). SAS was negatively correlated with age, family income, family support, satisfaction of objects service, and sleep quality (all <0.01), while positively correlated with gender, fatigue, fear of pneumonia, and duration of daily attention to the COVID-19 (all <0.01). CONCLUSIONS The front-line workers should manage work and rest time reasonably to adjust their negative mood and fatigue. The government and the society should pay more attention to the psychological state of the front-line staff, particularly for the staff working in the community or villages and towns in preventing the COVID-19 pandemic. Thus, front-line staff can be obtained mental intervention or be taken a rest from the high-intensive work.

Objective To observe the inhibitory effect of lentiviral vector miR-191 (LV-191) on retinal neovascularization (RNV) in mice model of oxygen-induced retinopathy (OIR).Methods Eighty healthy 7-day-old C57BL/6J mice were randomly divided into 5 groups including normal group, non-intervention group, normal saline (NS) group, LV-191 group and LV-green fluorescent protein (GFP) group, 16 mice in each group. The OIR model was established in the non-intervention group, NS group, LV-191 group and LV-GFP group. NS group, LV-191 group and LV-GFP group were given an intravitreal injection of 1 μl of NS, LV-191 and LV-GFP at the age of 12 days. No injection was performed in the non-intervention group. In normal group,newborn mouse were maintained in room air form P0 to P17, and no treatment was performed. Mice in all five groups were euthanized at P17. Retinal neovasculation (RNV) was evaluated by counting the number of pre-retinal neovascular cells and analysis of non-perfusion area area by immunofluorescent staining of the mouse retina. Real-time quantitative PCR (RT-PCR) to detect miR -191 and P21 expression of retinal tissue.Results In the LV-191 group, the non-perfusion area were both significantly smaller than those in non-intervention group, NS group and LV-GFP group (F=127.20,P<0.001). The number of pre-retinal neovascular cell nuclei in retinas from LV-191 group were obviously lower than those in the retinas from non-intervention group, NS group and LV-GFP group (F=31.71,P<0.05). RT-PCR showed that the LV-191 and P21 level of LV-191 group increased significantly than other groups (F=10.95, 15.60;P<0.05).Conclusion Intravitreal injection of LV-191 inhibits RNV in mice model of OIR possibly through up-regulating p21.

Objective To study the correlation between radial artery graft patency and the degree of native coronary stenosis in coronary artery bypass grafting. Methods The clinical data of 290 patients who had underwent off-pump coronary artery bypass grafting were retrospectively analyzed. The left internal mammary artery, radial artery and saphenous veins were as grafts. The patients were divided into 3 groups according to the stenosis of right coronary artery before operation:group Ⅰ(right coronary artery stenosis 50%-75%, 85 cases), groupⅡ(right coronary artery stenosis 76%-89%, 95 cases) and group Ⅲ (right coronary artery stenosis 90%-100%, 110 cases). The patients were followed up for 2 to 5 years, and the graft patency was assessed using CT coronary angiography. Results There was no death and serious complications in 3 groups. Among the 3 groups, the total graft patency rate of left internal mammary artery grafts was 93.3% (270/290), the total graft patency rate of saphenous veins grafts was 70.2%(433/617), and the total graft patency rate of radial artery grafts was 69.7%(202/290). There was no statistical difference in the graft patency rate of radial artery grafts between group Ⅱ and group Ⅰ(P>0.05). The graft patency rate of radial artery grafts in group Ⅲwas significantly higher than that in groupⅡand group Ⅰ:85.5%(94/110) vs. 68.4%(65/95) and 50.6%(43/85), and there was statistical difference (P<0.05). The graft patency rate of radial artery grafts was significantly higher than the graft patency rate of saphenous veins grafts in group Ⅲ :85.5%(94/110) vs. 71.5%(168/235), and there was statistical difference (P<0.05). There were no statistical differences in the graft patency rates of left internal mammary artery grafts and saphenous veins grafts among 3 group (P>0.05). Conclusions The correlation between radial artery graft patency and the degree of native coronary stenosis is significant in coronary artery bypass grafting. Patients with severe proximal right coronary artery stenosis (≥90%) may have better patency rates at mid-term follow up after using radial artery grafts.
