China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.

Objective To analyze the real experiences of patients with inflammatory bowel disease(IBD)during dietary restrictions,providing references for healthcare personnel to guide patients in standardizing dietary restriction behaviors.Methods Purposeful sampling was employed to select 14 patients with IBD who were treated at a tertiary A hospital in Shanghai between October 2022 and February 2023 for semi-structured in-depth interviews.Data were analyzed using the Colaizzi's 7-step method in phenomenological research.Results 4 themes and 13 sub-themes were extracted.Theme 1:facing multiple physiological challenges(hunger,nutritional imbalance,fatigue and muscle atrophy).Theme 2:experiencing negative psychological disturbances(craving and struggle for gourmet food,diminished zest for life and increased anxiety,feeling embarrassed during social activities).Theme 3:adopting various coping strategies(self-adjustment and adaptation to dietary restrictions,satisfying oral desires through various avenues,seeking knowledge and guidance on nutrition).Theme 4:gaining more growth and support(improved symptom and quality of life,enhanced awareness of dietary health,improved ability to manage diet,receiving support from peers and family).Conclusion The experience of dietary restrictions in IBD patients is complex and varied.Nursing staff should prioritize nutritional risk screening for IBD patients,pay attention to their mental health,provide patients with scientific and personalized dietary guidance,and strengthen social and family support to assist patients in better self-management of their diet.

OBJECTIVE To investigate the effect and mechanism of gracillin from Reineckia carnea on autophagy in non- small cell lung cancer A549 cells. METHODS Using A549 cells as subjects， the effects of different concentrations of gracillin （0.25， 0.5， 1， 2， 4 μmol/L） on the proliferation of cells were detected by CCK-8 after being treated for different time （12， 24， 48 h）. Compared with the control group without medication， the effect of gracillin （2 μmol/L） on the formation of autophagosomes in cells was observed by transmission electron microscope after 24 h of exposure. The aggregation of GFP-LC3 on autophagosome membrane was detected by GFP-LC3 plasmid transfection after being treated with gracillin （0.25， 0.5， 1， 2 μmol/L） for 24 h. Quantitative real-time PCR and Western blot assay were used to detect the mRNA and protein expressions of family with sequence similarity 102 member A（FAM102A）， the expressions of autophagy-related proteins [p62， Beclin-1， microtubule-associated protein 1 light chain 3B （LC3B）]， and the expressions of phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway-related proteins in A549 cells after being treated with gracillin （0.25， 0.5， 1 and 2 μmol/L） for 24 h. RESULTS Gracillin significantly inhibited the proliferation of A549 cells in a concentration- and time-dependent manner. The IC50 was 2.55 μmol/L at 24 h. After 24 h of gracillin treatment， autophagosomes with bilayer membrane structure were found in the cell cytoplasm， and GFP-LC3 green fluorescent spots on autophagosome membrane were obvious， representing an increasing trend as drug concentration. Compared with the control group， mRNA and protein expressions of FAM102A （0.5， 1， 2 μmol/L groups）， protein expression of Beclin-1 （1， 2 μmol/L groups） and LC3B-Ⅱ/LC3B-Ⅰ ratio （2 μmol/L group） were significantly increased in different concentrations of gracillin groups， while the protein expression of p62 （1， 2 μmol/L groups）， and the protein phosphorylations of Akt （1， 2 μmol/L groups） and PI3K （2 μmol/L group） were all decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Gracillin can promote excessive autophagy in A549 cells by up-regulating mRNA and protein expressions of FAM102A and inhibiting PI3K/Akt signaling pathway， thus inhibiting cell proliferation.

Objective To investigate the interventional effect and mechanism of a novel ampelopsis hydrogel on dampness-heat accumulation syndrome of gouty arthritis. Methods A total of 90 patients with gouty arthritis who met the diagnostic criteria of western medicine and were differentiated as damp-heat accumulation syndrome of traditional Chinese medicine(TCM) were randomly divided into treatment group, control group and blank group, with 30 patients in each group. The blank group was treated with etoricoxib only, the control group was treated with etoricoxib combined with ampelopsis hydrogel, and the treatment group was treated with etoricoxib combined with external application of ampelopsis hydrogel. The clinical efficacy, time to symptom improvement, safety, comfort, changes in syndrome scores of TCM, serum inflammatory factors[C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), erythrocyte sedimentation rate (ESR)], NF-κB signaling pathway-related proteins, Visual Analogue Scale (VAS) scores for pain, and joint mobility were compared among the three groups before and after treatment. Results The total effective rates in the treatment group and control group were 93.33% and 90.00%, respectively, which were higher than 70.00% in the blank group (P < 0.05). The time for improvement of pain, redness, tenderness, and limited joint mobility in the treatment group was shorter than that in the control group and blank group (P < 0.05). After 7 days of treatment, the TCM syndrome score in the treatment group was lower than that in the control group and blank group, and the levels of serum CRP, TNF-α, and ESR and the expressions of NF-κB signalingpathway-related proteins P50 and P65 in the treatment group and control group were lower than those in the blank group (P < 0.05). After 7 days of treatment, the VAS score in the treatment group was lower than that in the control group and blank group, and the comfort score in the treatment group was higher than that in the control group (P < 0.05). There was no significant difference in the incidence of adverse reactions among the three groups (P>0.05). Conclusion The effect of ampelopsis hydrogel in treating gouty arthritis is better than that of ampelopsis paste, and its mechanism may be related to the regulation of the NF-κB pathway and inhibition of inflammatory factor expression. The hydrogel is easy to use, hygienic, and comfortable, and is expected to become a safe, effective, and convenient external medicine for gouty arthritis.

The individuals in the control group received traditional teaching, and those in the observation group received CBL combined with online teaching. The physicians receiving standardized residency training were evaluated by theoretical examination, clinical operation skill assessment, and instructor rating, and the degree of satisfaction with teaching, degree of satisfaction with teaching methods, and classroom learning atmosphere were also evaluated.Results:The observation group had a theoretical examination score of (94.10±2.01) and a clinical operation skill assessment score of (90.44±1.57), which were significantly higher than those of the control group ( P<0.05), and the observation group had a significantly better instructor rating (89.36±1.33) than the control group ( P<0.05). Compared with the control group, the observation group had significantly higher degree of satisfaction with teaching (3.79±0.41), degree of satisfaction with teaching methods (3.92±0.27), and evaluation of classroom learning atmosphere (3.90±0.31) ( P<0.05). Conclusion:CBL combined with online teaching can help to improve learning efficiency, stimulate the enthusiasm for learning, expand clinical thinking, promote the growth of teaching and learning, and form a virtuous cycle among trainees receiving standardized residency training, which holds promise for further exploration.

Objective:To explore the application effect of quantitative evaluation nursing in Operating Room in patients undergoing radical resection of rectal cancer.Methods:A total of 114 patients who received radical resection of rectal cancer in Xi'an Daxing Hospital from December 2019 to December 2021 were selected by the convenient sampling method. According to the order of admission, they were divided into the observation group and the conventional group, with 57 cases in each group. The observation group received quantitative evaluation nursing in the Operating Room, while the conventional group received routine Operating Room nursing. The differences in physiological indexes and mood state scores were compared between the two groups.Results:The postoperative diastolic blood pressure, systolic blood pressure and heart rate in the observation group were lower than those in the conventional group ( P<0.05). The scores of depression-frustration, tension-anxiety, fatigue-dullness, anger-hostility and confusion-chaos dimensions of postoperative mood state in the observation group were lower than those in the conventional group, and the energy-vitality score was higher than that in the conventional group ( P<0.05) . Conclusions:Quantitative evaluation nursing in the Operating Room can reduce the psychosomatic stress response in patients undergoing radical resection of rectal cancer.

Objective:To observe the changes of relevant clinical indicators and ultrasound pre-sentations in rheumatoid arthritis (RA) patients after being treated with tocilizumab for 3 months and explore the efficacy and safety of tocilizumab in the treatment of RA.Methods:Clinical data, laboratory and ultrasound examinations and medications of RA patients who met inclusion criteria in our hospital from Jan-uary 2017 to September 2020 were included and their data were analyzed retrospectively, and the efficacy and safety of tocilizumab and the ultrasound assessment of disease remission were analyzed. Paired sample t test, Wilcoxon signed-rank test, χ2 test or Fisher's exact probability test were used for comparative analysis. Results:① Compared with baseline data, morning stiffness duration of patients treated with tocilizumab for 3 months [60(30, 120) min vs 0(0, 10) min, Z=-6.19, P<0.001], disease activity score of 28 joints-erythrocyte sedimentation rate (DAS28-ESR) [(4.6±1.5) vs (3.2±1.2), t=6.83, P<0.001], disease activity score of 28 joints-C-reactive protein (DAS28-CRP) [(4.2±1.4) vs (2.8±1.1), t=7.14, P<0.001], swollen joint count (SJC) [2(1, 7) vs 0(0, 2), Z=-4.31, P<0.001], tender joints count (TJC) [6(2, 13.5) vs 2(0,4), Z=-5.16, P<0.001], gray scale score (GS) [4.5(2, 6) vs 1(0, 3), Z=-5.86, P<0.001], intra-synovial blood flow energy Doppler (PD) [2(1, 3) vs 0(0, 0), Z=-5.38, P<0.001], white blood cell (WBC) [6.6(4.9, 8.4)×10 9/L vs 5.7(4.9, 7.3)×10 9/L, Z=-2.83, P=0.005], hemoglobin (Hb) [119(104, 131) g/L vs 123(113, 136) g/L, Z=-2.82, P=0.007], ESR [32(14.5, 50) mm/1 h vs 19 (10, 30) mm/1 h, Z=-3.31, P=0.001], CRP [11.40(3.02, 25.80) mg/L vs 3.49(1.30, 11.82) mg/L, Z=-2.78, P=0.004], D-dimer (D-D) [0.93(0.47, 2.07) mg/L vs 0.43(0.21, 0.80) mg/L, Z=-3.77, P<0.001] were significantly improved, and the difference was statistically significant. ② The serum levels of interleukin (IL)-2 [2.08(1.43, 2.76) pg/ml vs 1.21(0.54, 2.08) pg/ml, Z=-2.67, P=0.008], IL-6 [22.40(5.13, 67.27) pg/ml vs 14.63(5.27, 27.71) pg/ml, Z=-2.81, P=0.005], IL-10 [(2.53±0.68) pg/ml vs (1.74±0.74) pg/ml, t=2.60, P=0.017] were significantly changed, while serum levels of IL-4 [1.63(1.08, 3.38) pg/ml vs 1.33(0.97, 2.59) pg/ml, Z=-0.89, P=0.374], tumor necrosis factor (TNF) -α [4.04(1.41, 10.45) pg/ml vs 1.62(0.84, 3.79) pg/ml, Z=-1.92, P=0.056], IL-17 [4.68(1.67, 6.72) pg/ml vs 3.15(1.81, 5.29) pg/ml, Z=-0.53, P=0.594] were not significantly changed from baseline data. ③ There was poor consistency between ultrasonic response and DAS28-ESR response, simplified disease activity Index (SDAI) response and clinical disease activity index (CDAI) response ( Kappa coefficient: 0.142, 0.142, 0.191), but no consistency between ultrasonic response and DAS28-CRP response (Kappa coefficient: -0.015) were found. Receiver operating characteristic (ROC) curve showed that ultrasound was not statistically significantly different in assessing the remission of RA, indicating subclinical synovitis remained in ultrasound examination even though clinically remission could be reached based on the above scoring indexes in RA patients. ④ In terms of adverse reactions, neutrophils (NEU) of patients after 3 months' tocilizumab treatment [4.47(2.77, 5.39)×10 9/L vs 3.76(2.98, 4.74)×10 9/L, Z=-2.77, P=0.006], platelet count (PLT) [(291±84)×10 9/L vs (254±70)×10 9/L, t=4.76, P<0.001] were significantly decreased, high-density lipoprotein-cholesterol (HDL-C) [(1.22±0.27) mmol/L vs (1.39±0.34) mmol/L, t=3.12, P=0.003], low density lipoprotein-cholesterol (LDL-C) [(1.96±0.66) mmol/L vs (2.19±0.84) mmol/L, t=3.15, P=0.003], triglyceride (TG) [0.85(0.68, 1.08) mmol/L vs 0.93(0.71, 1.25) mmol/L, Z=-2.36, P=0.018] and total cholesterol (TC) [(4.18±1.04) mmol/L vs (4.52±1.16) mmol/L, t=3.33, P=0.002] were significantly different from baseline. Among 65 patients, 5 patients (7.7%) had transaminase abnormality, but returned to normal after symptomatic treatment. Conclusion:Tocilizumab treatment can effectively suppress the inflammatory reactions, improve the clinical symptoms and prognosis of patients, however, patients who judged as clinical remission according to the current clinical commonly scores may still have subclinical active disease, ultrasound results should be included as one criteria for disease remission assessment and take into consideration when adjusting treatrnent.
