Occupational exposure to ionizing radiation represents a critical factor contributing to health risks in workplaces. Previous experimental and clinical studies have demonstrated that ionizing radiation affects human health. Therefore, scientific assessment of health risk caused by ionizing radiation and effective protection against ionizing radiation are of great importance to formulate the preventive interventions against occupational exposure to ionizing radiation. This review summarizes the advances in the research on health effects, health risk assessment methods, and protective interventions of ionizing radiation. We call for research on the health effects of low-dose radiation, individual difference, and optimization of preventive strategies. In addition, improved mechanisms of health monitoring, periodical healthy examinations, and monitoring of radiation doses should be implemented. Moreover, strict compliance to operating procedures and occupational preventive interventions are recommended. These measures aim to minimize the potential harmlessness of occupational exposure to ionizing radiation, thereby safeguarding the health and safety of individuals exposed to ionizing radiation.

BACKGROUND@#Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients.@*METHODS@#AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE.@*RESULTS@#During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants.@*CONCLUSIONS@#In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

Objective:To summarize the levels of individual dose to radiation workers in Shandong province from 2016 to 2020, and to analyze the trends in their change in order to provide scientific basis for radiation workers′ health management.Methods:The experimental detection and quality control were carried out in compliance with the national standards Specifications for individual monitoring of occupational external exposure (GBZ 128-2019) and the Testing criteria of personnel dosimetry performance for external exposure (GBZ 207-2016). The result of the personal dose monitoring of occupational external exposure of all radiation workers monitored by the Centers for Disease Control and Prevention in 16 cities of Shandong province were retrospectively analyzed by using SPSS 23.0 software.Results:The total number of monitored workers were 25 523 with an average annual individual effective dose of 0.28 mSv. There were statistically significant differences among radiation workers in different years ( H= 2 815.91, P<0. 001). The average annual individual effective dose showed an upward trend followed by a downward trend. The average annual effective dose of 0.55 mSv for nuclear medicine radiation workers in medical applications was the highest, with statistically significant differences among different occupational radiation workers ( H=310.37, P<0.001). The average annual effective dose of 0.37 mSv for radioactivity logging workers in industrial applications was the highest, with statistically significant differences among different occupational radiation workers ( H=448.07, P<0. 001). The average annual effective dose to radiation workers in medical applications was higher than in industrial applications ( Z = -14.93, P<0.001). Conclusions:The average annual effective dose to nuclear medicine radiation workers in medical applications and logging radiation workers in industrial applications are relatively high. There would be a push to furthe improve workplace protection measures and strengthen the management and supervision of radiological workers.

At present, China’s response to the aging population situation is unprecedentedly urgent, and the construction and planning of the pension system face great challenges. Home-based elderly care services stand out in institutional-based elderly care and family-based elderly care due to their unique advantages in meeting the individual needs of the elderly. By sorting out the main types, policy lines, and supply and demand status of home-based elderly care service, this paper indicated that there are five aspects of problems in home-based elderly care service, including weak professional talent team construction, relatively insufficient capital investment, weak supply-demand matching, imperfect operating mechanism, and imperfect supporting facilities. It was proposed that in the future home-based elderly care services should strive to strengthen the construction of professional talent teams, widen financing channels, fully play the leading role of the government, perfect the operational mechanism and the construction of supporting facilities of home-based elderly care services, so as to provide reference for the optimization of the home-based elderly care service system in China.

Objective:To explore the value of subspecialty group collaboration combined with disease checklist-driven learning in overcoming the impact of the specialized disease treatment mode in subspecialty establishment on the cultivation of professional postgraduate students.Methods:In the teaching of general surgery and gastroenterology, sixty professional postgraduate students of grade 2019 were randomly divided into control group and experimental group, with 30 students in each group. The control group received traditional teaching, while the experimental group received the teaching mode of subspecialty group collaboration combined with disease checklist-driven learning. The teaching effectiveness and the degree of satisfaction with teaching were compared between the two groups. The data were analyzed using the t test and the chi-squared test using SPSS 20.0. Results:In actual teaching, compared with the control group, the experimental group showed significantly higher scores of theoretical assessment (71.51±11.32 vs. 87.23±10.51, P<0.05) and case analysis (73.61±6.82 vs. 92.37±6.87, P<0.05). The rates of satisfaction with theoretical knowledge learning, application of clinical thinking ability for diseases, teaching organization forms, and teaching effectiveness were 90.00%(27/30), 86.67%(26/30), 96.67%(29/30), and 93.33%(28/30) in the experimental group, respectively, which were significantly higher than those of the control group [40.00%(12/30), 23.33%(7/30), 40.00%(12/30), and 46.67%(14/30), respectively; all P<0.05]. Conclusions:The subspecialty group collaboration combined with disease checklist-driven learning mode can overcome the problems of "narrow disease spectrum and narrow knowledge scope" in specialized postgraduate education, and guide students to break the teaching barriers generated by subspecialty construction to create a new form of comprehensive and multi-disease learning, with good prospects for promotion and application.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

Objective: To investigate current use of oral anticoagulant (OAC) therapy and influencing factors among coronary artery disease (CAD) patients with nonvalvular atrial fibrillation (NVAF) in China. Methods: Results of this study derived from "China Atrial Fibrillation Registry Study", the study prospectively enrolled atrial fibrillation (AF) patients from 31 hospitals, and patients with valvular AF or treated with catheter ablation were excluded. Baseline data such as age, sex and type of atrial fibrillation were collected, and drug history, history of concomitant diseases, laboratory results and echocardiography results were recorded. CHA2DS2-VASc score and HAS-BLED score were calculated. The patients were followed up at the 3rd and 6th months after enrollment and every 6 months thereafter. Patients were divided according to whether they had coronary artery disease and whether they took OAC. Results: 11 067 NVAF patients fulfilling guideline criteria for OAC treatment were included in this study, including 1 837 patients with CAD. 95.4% of NVAF patients with CAD had CHA2DS2-VASc score≥2, and 59.7% of patients had HAS-BLED≥3, which was significantly higher than NVAF patients without CAD (P<0.001). Only 34.6% of NVAF patients with CAD were treated with OAC at enrollment. The proportion of HAS-BLED≥3 in the OAC group was significantly lower than in the no-OAC group (36.7% vs. 71.8%, P<0.001). After adjustment with multivariable logistic regression analysis, thromboembolism(OR=2.48,95%CI 1.50-4.10,P<0.001), left atrial diameter≥40 mm(OR=1.89,95%CI 1.23-2.91,P=0.004), stain use (OR=1.83,95%CI 1.01-3.03, P=0.020) and β blocker use (OR=1.74,95%CI 1.13-2.68,P=0.012)were influence factors of OAC treatment. However, the influence factors of no-OAC use were female(OR=0.54,95%CI 0.34-0.86,P=0.001), HAS-BLED≥3 (OR=0.33,95%CI 0.19-0.57,P<0.001), and antiplatelet drug(OR=0.04,95%CI 0.03-0.07,P<0.001). Conclusion: The rate of OAC treatment in NVAF patients with CAD is still low and needs to be further improved. The training and assessment of medical personnel should be strengthened to improve the utilization rate of OAC in these patients.

Objective: Explore the association between atrial fibrillation (AF) reoccurrence and new-onset ischemic stroke (IS) in patients with nonvalvular AF, and explore whether there is a high-risk period of IS after recurrent episodes of AF. Methods: A nested case-control study design was used. A total of 565 nonvalvular AF patients with new-onset IS after a follow-up of at least 2 years in the China-AF cohort were enrolled as the case group, and 1 693 nonvalvular AF patients without new-onset IS were matched as the control group at a ratio of 1∶3. Frequency and types of recurrent AF in the previous 1 or 2 years were compared between two groups, and the adjusted associations of AF reoccurrence with new onset IS were explored using conditional logistic regression analysis. The proportion of recurrent AF was compared between the case period and control period, and conditional logistic regression analysis was performed to calculate adjusted associations of case-period AF with IS. Results: The nested case-control study design results showed that the proportion of at least one record of recurrent AF in the previous 1 year was higher in the case group than in the control group (72.0% vs. 60.8%, P<0.05), and the recurrent AF was positively correlated with new-onset IS (adjusted OR=1.80, P<0.001). Similar results were also observed in the previous 2 years period. The case-crossover study design analysis showed that among 565 patients with new-onset IS, recurrent AF in the case period was positively correlated with IS (adjusted OR=1.61, P=0.003). Conclusion: Recurrent AF is associated with IS, and there may be a high-risk period of IS after recurrent episodes of AF.

This study aims to develop a rapid and convenient test card for simultaneous detection of influenza A and influenza B viruses using quantum dot-based immunochromatographic assay. The test card consists of a test strip and a plastic casing. The test strip is composed of absorbent paper, a buffer pad, nitrocellulose membrane (NC membrane), sample pad, quantum dot-labeled antibody pad, and polyvinyl chloride (PVC) board. The NC membrane is coated with mouse monoclonal antibodies against influenza A and influenza B viruses for the T lines (test lines), and reference proteins A and B for the C line (control line). The quantum dot-labeled antibody pad contains mouse monoclonal antibody-quantum dot conjugates against influenza A and influenza B viruses. The results showed that the detection limit of the test card for both viruses ranged from 1.51 ×102 to 2.71×103 TCID50/ml, indicating its sensitivity for accurate detection of influenza A and influenza B viruses without being affected by various variants. The test card exhibited specific reactions with different subtypes of influenza A and influenza B virus culture fluids and showed no cross-reactivity with adenovirus, novel coronavirus, Mycoplasma pneumoniae, respiratory syncytial virus, Staphylococcus aureus, and other pathogens. Overall, the sensitivity and specificity of the test card for simultaneous detection of influenza A and influenza B viruses meet the requirements for clinical use. It offers the advantages of simplicity, rapidity, and no requirement for special equipment, enabling quick auxiliary diagnosis to prevent disease transmission.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Objective: To explore the relationship between fasting blood glucose level and thromboembolism events in patients with non-valvular atrial fibrillation (NVAF). Methods: This was an observational study based on data from a multicenter, prospective Chinese atrial fibrillation registry cohort, which included 18 703 consecutive patients with atrial fibrillation (AF) in 31 hospitals in Beijing from August 2011 to December 2018. Patients were divided into 5 groups according to status of comorbid diabetes and fasting glucose levels at admission: normal blood glucose (normal glucose group), pre-diabetes group, strict glycemic control group, average glycemic control group and poor glycemic control group. Patients were followed up by telephone or outpatient service every 6 months. The primary follow-up endpoint was thromboembolic events, including ischemic stroke and systemic embolism. The secondary endpoint was the composite endpoint of cardiovascular death and thromboembolic events. Kaplan-Meier survival analysis and multifactorial Cox regression were used to analyze the correlation between fasting glucose levels and endpoint events. Results: The age of 18 703 patients with NVAF was (63.8±12.0) years, and there were 11 503 (61.5%) male patients. There were 11 877 patients (63.5%) in normal blood glucose group, 2 023 patients (10.8%)in pre-diabetes group, 1 131 patients (6.0%) in strict glycemic control group, 811 patients in average glycemic control group and 2 861 patients(4.3%) in poor glycemic control group. Of the 4 803 diabetic patients, 1 131 patients (23.5%) achieved strict glycemic control, of whom 328 (29.0%) were hypoglycemic (fasting blood glucose level<4.4 mmol/L at admission). During a mean follow-up of (51±23) months (up to 82 months), thromboembolic events were reported in 984 patients (5.3%). The survival curve analysis of Kaplan Meier showed that the incidence rates of thromboembolic events in normal glucose group, pre-diabetes group, strict glycemic control group, average glycemic control group and poor glycemic control group were 1.10/100, 1.41/100, 2.09/100, 1.46/100 and 1.71/100 person-years, respectively (χ²=53.0, log-rank P<0.001). The incidence rates of composite endpoint events were 1.86/100, 2.17/100, 4.08/100, 2.58/100, 3.16/100 person-years (χ²=72.3, log-rank P<0.001). The incidence of thromboembolic events and composite endpoint events in the other four groups were higher than that in the normal blood glucose group (P<0.001). Multivariate Cox regression analysis showed that compared with normal glucose group, the risk of thromboembolism increased in pre-diabetes group(HR=1.23, 95%CI 1.00-1.51, P=0.049), strict glycemic control group(HR=1.32, 95%CI 1.06-1.65, P=0.013) and poor glycemic control group(HR=1.26, 95%CI 1.01-1.58, P=0.044). Conclusion: Both high or low fasting glucose may be an independent risk factor for thromboembolic events in patients with NVAF.

Objective:To study minimally invasive treatment using percutaneous transhepatic choledochoscopic lithotripsy (PTCSL) to treat complicated hepatolithiasis.Methods:Patients with complicated hepatolithiasis who were treated at the Second Affiliated Hospital of Kunming Medical University from July 2017 to September 2021, were included into this study. There were 48 patients treated with PTCSL (the PTCSL group) and 150 patients treated with conventional open hepatectomy (the OH group). Propensity score matching (PSM) was used to match 40 patients in the PTCSL group with 40 patients in the OH group. There were 11 males and 29 females, aged 32 to 85 (59.3±12.7) years in the PTCSL group and 15 males and 25 females, aged 20 to 74 (55.4±10.9) years in the OH group. Theoperation time, intraoperative blood loss, hospitalization time, hospitalization cost, incidences of major complications (including pleural effusion, biliary bleeding), residual stone rates and recurrence rates were analyzed.Results:Baseline data were comparable between groups after PSM. For the PTCSL group, the operation time was (135.8±42.6) minutes, intraoperative bleeding volume 32.5(20.0, 50.0) ml, hospitalization time 13.5(11.0, 18.0) days, and hospitalization expense 3.4(2.9, 5.0) wanyuan compared with the corresponding figures in the OH group with operation time (350.7±113.8) minutes, intraoperative bleeding volume 475.0(200.0, 900.0) ml, hospitalization time 24.0(17.3, 28.8) days, and hospitalization expense 6.6(5.0, 8.9) wanyuan. The differences between the two groups were statistically significant (all P<0.05). The overall complication rate was 2.5%(1/40) in the PTCSL group and 22.5%(9/40) in the OH group (χ 2=7.31, P=0.007). The residual stone rate of 20.0%(8/40), stone recurrence rate of 17.5%(7/40), compared with the OH group with the stone residual rate of 27.5%(11/40), stone recurrence rate of 12.5%(5/40). There was no significant difference between the two groups in both the stone residual rates and stone recurrence rates (both P>0.05). Conclusion:In treatment of complex hepatolithiasis, the stone residual rate after repeated PTCSL was comparable to traditional open hepatectomy. PTCSL had the advantages of shorter operation time, less bleeding, lower hospitalization time, lower complication rate and lower hospitalization cost. PTCSL is worthy of wider application and popularization.

Objective:To investigate the prognostic value of pretreatment 18F-FDG PET/CT metabolic parameters in patients with elderly classical Hodgkin′s lymphoma (cHL). Methods:From April 2011 to April 2020, the pretreatment clinical and 18F-FDG PET/CT metabolic parameters of 42 elderly cHL patients (29 males and 13 females, median age 69 years) pathologically confirmed in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were obtained with 41%SUV max as the threshold. ROC curve analysis was applied to obtain the best prognostic cut-off value of SUV max, MTV and TLG. Kaplan-Meier method and log-rank test were used for univariate survival analysis, and Cox proportional hazard regression model was used for multivariate survival analysis. Results:SUV max, MTV and TLG of 42 elderly cHL patients were 16.49(12.24, 23.59), 79.29(26.29, 184.51) ml and 729.02(206.03, 2 073.98) g, respectively. ROC curve showed that the AUCs of SUV max, MTV and TLG were 0.425, 0.882 and 0.832, respectively, and the best prognostic cut-off values were 16.49, 82.38 ml and 556.26 g, respectively. Univariate analysis showed that age, B symptoms, lactate dehydrogenase (LDH) level, Hb content, Ann Arbor stage, German Hodgkin Study Group (GHSG) score, MTV and TLG were relative factors affecting progression-free survival (PFS) rate ( χ2 values: 4.50-12.60, all P<0.05), and age, B symptoms, LDH level, Ann Arbor stage, GHSG score, MTV and TLG were relative factors affecting overall survival (OS) rate ( χ2 values: 5.20-11.17, all P<0.05). Multivariate analysis showed that MTV (relative risk ( RR)=5.370, 95% CI: 1.697-16.277) and TLG ( RR=4.854, 95% CI: 1.228-23.352) were independent prognostic predictors of PFS rate (both P<0.05), and GHSG score ( RR=3.761, 95% CI: 1.092-12.955; RR=3.668, 95% CI: 1.068-12.571), MTV ( RR=6.173, 95% CI: 1.431-16.322) and TLG ( RR=5.162, 95% CI: 1.200-22.199) were independent prognostic predictors of OS rate (all P<0.05). Conclusion:MTV and TLG in pretreatment 18F-FDG PET/CT are independent prognostic factors for predicting PFS and OS in patients with elderly cHL patients, which have certainly reference value for prognosis.

【Objective】 To investigate scalp acupuncture’s protective effect on brain neurons and its effect on motor function in ischemic stroke rats and the possible mechanisms. 【Methods】 The rat model of ischemic stroke was prepared by the modified Longa suture method; the rats were randomly divided into model group, scalp acupuncture treatment group, inhibitor group, scalp acupuncture treatment + inhibitor group, and sham operation group. After a series of interventions, we evaluated the neurological, behavioral and motor functions of rats in each group after the treatment was over. TTC staining was used to detect cerebral infarction area. Neuron morphology was observed by Nissl staining. qPCR and Western blotting were used to detect the mRNA and protein expression levels of genes related to phosphatidyl inositol-3-kinase (PI3K)/serine-threonine protein kinase (AKt) pathway in the ischemic brain tissue of the rats. 【Results】 In the inhibitor group, the model group, the scalp acupuncture treatment group, and the scalp acupuncture treatment+inhibitor group, the neurological impairment and motor function score gradually decreased, the escape latency gradually shortened, the target quadrant residence time prolonged, the proportion of cerebral infarction area decreased, the number of Nissl bodies increased, the relative expressions of PI3K and AKt mRNA and protein increased (P<0.05), and the neuronal morphology improved. 【Conclusion】 Scalp acupuncture can protect cerebral neurons of rats with ischemic stroke and enhance their motor function. The mechanism may be related to the regulation of PI3K/AKt signaling pathway.
