ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke （AIS） patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging （DCE-MRI）. MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method，the patients were assigned into a control group （32 cases） and an observation group （31 cases）. The control group received conventional Western medical treatment，and the observation group took 200 mL Tongnaoyin after meals，twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment，the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale （NIHSS） score and modified Rankin Scale （mRS） score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans，rKep，and rVe values were obtained from the region of interest （ROI） of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment，the NIHSS and mRS scores declined in both groups，and the observation group had lower scores than the control group （P<0.05）. After treatment，the rKtrans and rVe in the observation group were lower than those in the control group （P<0.01）. ConclusionCompared with conventional Western medical treatment alone，conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients，thereby ameliorating neurological impairment after AIS to improve the prognosis.

The 20th National Congress of the Communist Party of China emphasized the expansion of international scientific and technological exchanges and cooperation. Against this backdrop, the radiological health research institutions bear important responsibilities in the field of international radiological health. As a key institution in the industry, the National Institute for Radiological Protection (NIRP), Chinese Center for Disease Control and Prevention shoulders the important mission of promoting international exchanges in radiation health in China. A case study was conducted on the NIRP using data of official overseas visits from 2010 to 2024. The SWOT analysis was used to comprehensively and systematically examine the strengths, weaknesses, opportunities, and challenges of NIRP in international cooperation and exchanges. To effectively enhance the depth and scope of international exchanges, this article proposes a series of innovative optimization strategies such as establishing dedicated personnel positions to ensure efficient handling of affairs, implementing stringent approval procedures to guarantee the rationality and compliance of overseas visits, strengthening pre-departure training to improve the professionalism of outbound personnel, conducting follow-up evaluations to continuously refine management practices, and centralizing the management of official passports to ensure their secure use. This article aims to provide practical optimization strategies for the management of official overseas visits for NIRP and other similar institutions, promote international exchanges and cooperation in the field of radiation health, and help China play a more important role in the global radiation health field.

Objective To discuss the value of clinical radiomic nomogram(CRN)and deep convolutional neural network(DCNN)in distinguishing atypical pulmonary hamartoma(APH)from atypical lung adenocarcinoma(ALA).Methods A total of 307 patients were retrospectively recruited from two institutions.Patients in institu-tion 1 were randomly divided into the training(n=184:APH=97,ALA=87)and internal validation sets(n=79:APH=41,ALA=38)in a ratio of 7∶3,and patients in institution 2 were assigned as the external validation set(n=44:APH=23,ALA=21).A CRN model and a DCNN model were established,respectively,and the performances of two models were compared by delong test and receiver operating characteristic(ROC)curves.A human-machine competition was conducted to evaluate the value of AI in the Lung-RADS classification.Results The areas under the curve(AUCs)of DCNN model were higher than those of CRN model in the training,internal and external validation sets(0.983 vs 0.968,0.973 vs 0.953,and 0.942 vs 0.932,respectively),however,the differences were not statistically significant(p=0.23,0.31 and 0.34,respectively).With a radiologist-AI com-petition experiment,AI tended to downgrade more Lung-RADS categories in APH and affirm more Lung-RADS cat-egories in ALA than radiologists.Conclusion Both DCNN and CRN have higher value in distinguishing APH from ALA,with the former performing better.AI is superior to radiologists in evaluating the Lung-RADS classification of pulmonary nodules.

Objective:To investigate the effect of roxadustat combined with levocarnitine in the treatment of renal anemia in hemodialysis patients with diabetic kidney disease (DKD), and its effects on iron metabolism, microinflammation status and microvascular complications.Methods:The clinical data of 89 hemodialysis renal anemia patients with DKD from January 2020 to October 2021 in Beijing Geriatric Hospital were retrospectively analyzed. Among them, 44 patients (control group)were treated with recombinant human erythropoietin and levocarnitine for renal anemia, and 45 patients (study group) were treated with recombinant human erythropoietin, levocarnitine and roxadustat for renal anemia. Both groups were treated for 3 months. The efficacy was compared between two groups. The laboratory indexes were measured before treatment and after 1, 3 months of treatment, including anemia related indexes such as hemoglobin, red blood cell count and mean corpuscular volume (MCV); iron metabolism indexes such as serum iron, ferritin and transferrin saturation (TSAT); inflammatory indexes such as interleukin-8 (IL-8), C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α). The adverse reactions were recorded. The patients were followed up for 1 year after treatment, the incidence of diabetic microvascular complications, including diabetic peripheral neuropathy (DPN) and diabetic retinopathy (DR), was recorded.Results:The total effective rate in study group was significantly higher than that in control group: 93.33% (42/45) vs. 77.27% (34/44), and there was statistical difference ( χ2 = 4.60, P<0.05). There were no statistical differences in the laboratory indexes before treatment between two groups ( P<0.05); the hemoglobin, red blood cell count, MCV, serum iron, ferritin and TSAT after 1 and 3 months of treatment in study group were significantly higher than those in control group, the IL-8, CRP and TNF-α were significantly lower than those in control group, and there were statistical differences ( P<0.01 or <0.05). There was no significant difference in the incidence of adverse reactions between two groups ( P>0.05). After 1 year follow-up, 2 cases were lost in study group and 3 cases in the control group. The incidence of DR and DPN in study group were significantly lower than those in control group: 0 vs. 14.63% (6/41) and 2.33% (1/43) vs. 19.51% (8/41), and there were statistical differences ( χ2 = 4.75 and 4.81, P<0.05). Conclusions:Roxadustat combined with levocarnitine in the treatment of renal anemia in hemodialysis patients with DKD is reliable and safe, and can effectively relieve anemia symptoms, improve iron metabolism, reduce inflammatory response, and reduce the risk of diabetic microvascular complications.

Objective:To compare the clinical and ultrasonic features of elderly-onset rheumatoid arthritis(EORA)and young-onset rheumatoid arthritis(YORA).Methods:A total of 104 patients diagnosed with rheumatoid arthritis were categorized into two groups based on their age of onset: the EORA group, consisting of 70 patients, and the YORA group, consisting of 34 patients.A comparative analysis was conducted on the clinical manifestations, laboratory findings, and ultrasonic images of patients in these two groups.Results:The male ratio in the EORA group was significantly higher than that in the YORA group(24.3% vs.8.8%, P=0.048).There were no statistical differences in the course of disease, DAS28, ESR, CRP, RF, and anti-CCP antibody positive rates between the two groups( P>0.05)when compared with the YORA group.The incidence of osteoarthritis and osteoporosis in the EORA group was significantly higher than that in the YORA group( P=0.018, P=0.011).Ultrasonic results revealed a significantly higher incidence of phalangeal bone erosion in the EORA group compared to the YORA group(14.9% vs.4.3%, P<0.01).Binary logistic regression analysis indicated that different age groups, disease duration, osteoarthritis, and osteoporosis did not have an effect on the ultrasonic changes of synovial hyperplasia, tendonitis, tenosynovitis, and bone erosion in RA patients. Conclusions:There is no significant difference in the clinical disease activity and disease progression between EORA group and YORA group.Additionally, the pattern of joint inflammation involvement is similar in both groups.Ultrasound examinations revealed a higher incidence of bone erosion in finger joints of EORA patients compared to YORA patients.
