Objective To analyze the unexamined items and situations in occupational health examinations of radiation workers, and provide a reference for the revision of occupational health examination standards for radiation workers. Methods A total of 29 630 radiation workers who underwent occupational health examinations at The Third People’s Hospital of Henan Province in 2023 were selected, and the non-examination rates were statistically analyzed according to occupation, gender, and age. Results The overall non-examination rate of non-medical radiation workers was significantly lower than that of the medical radiation workers (P<0.05). The non-examination rate of chest X-rays among medical radiation workers was significantly higher than that of non-medical radiation workers (P<0.05), while no significant differences were found in other items (P>0.05). Gender-stratified analysis showed that the non-examination rate of routine urine tests was higher in females than in males in both medical and non-medical radiation workers (P<0.05). Age-stratified analysis revealed no significant differences in non-examination rates among different age groups in non-medical radiation workers (P>0.05), whereas the chest X-ray non-examination rate was relatively high in medical radiation workers under 30 years old (P<0.05). Conclusion Significant differences were observed in the non-examination rates of occupational health examinations among radiation workers based on occupation, gender, and age. The overall non-examination rate was relatively low in non-medical radiation workers.

Objective: To analyze the trend of disease burden of hearing loss attributable to occupational noise exposure in China from 1990 to 2021, so as to provide the evidence for optimizing noise prevention strategies and occupational health surveillance systems. Methods: Data on disability-adjusted life years (DALY) and age-standardized DALY rate (ASDR) for hearing loss attributable to occupational noise exposure in China from 1990 to 2021 were collected from the Global Burden of Disease 2021 database. The estimated annual percent change (EAPC) was used to analyze the trend in ASDR from 1990 to 2021. Results: From 1990 to 2021, the DALY for hearing loss attributable to occupational noise exposure in China increased from 1.279 7 million person-years to 2.683 9 million person-years, and the ASDR increased from 123.08/105 to 133.99 /105 (EAPC=0.324%, 95%CI: 0.296%-0.352%). From 1990 to 2021, the ASDR for hearing loss attributable to occupational noise exposure among males and females in China increased from 141.04/105 and 104.92/105 to 149.99/105 and 118.06/105, with EAPC values of 0.269% (95%CI: 0.231%-0.307%) and 0.413% (95%CI: 0.392%-0.433%). In 1990, the 60-65 years age group had relatively high DALY and ASDR, with 0.157 6 million person-years and 446.06/105, respectively. In 2021, the ≥70 years group had relatively high DALY of 0.434 7 million person-years, while the 60-<65 years group had relatively high ASDR of 510.64/105. Except for the 15-20 and 20-25 years groups, all other age groups showed an increasing trend in ASDR for hearing loss attributable to occupational noise exposure from 1990 to 2021. Among them, the ASDR increased faster in the 55-<60, 60-<65, 65-<70, and ≥70 years groups, with EAPC values of 0.364% (95%CI: 0.311%-0.417%), 0.459% (95%CI: 0.389%-0.529%), 0.564% (95%CI: 0.505%-0.623%), and 0.295% (95%CI: 0.212%-0.377%), respectively. Conclusions From 1990 to 2021, the disease burden of hearing loss attributable to occupational noise exposure in China showed an increasing trend. Males, the elderly had a higher disease burden, while the burden increased faster in females and middle-aged and elderly populations.

This study explored the ideas and methods of acupuncture for Guillain-Barré Syndrome （GBS） with the core principle of “to treat flaccidity， select the yangming （阳明） channel only”. The main pathological mechanism of GBS is deficiency of qi and blood in the yangming channel， malnutrition of all sinews， diminished spleen and stomach function leading to the production of pathogenic damp-heat qi， which obstructs the meridians， and gradually affects the liver and kidneys， consuming essence and damaging blood. Concurrently， dysfunction of the dumai （督脉） pivotal mechanism and lack of moisture in sinews and vessels result in symptoms such as skin numbness， paralysis， and muscle wastage. In clinical diagnosis and treatment， a combination of syndrome and channel differentiation is taken. Treatment primarily focuses on acupoints of yangming channel， aiming to supplement qi and blood， and acupoints of du mai are combined to open the vessel and fill the marrow. Specific acupoints are selected based on syndrome differentiation， providing comprehensive regulation to promote harmonization of qi and blood， relieve meridians， and the smooth generation and circulation of whole body fluids. This， in turn， enhances the strength of muscles and bones， and fosters a robust and freely moving body.

Objective:To summarize the clinical manifestations and diagnostic methods of adult neuronal intranuclear inclusion disease (NIID), improve understanding of the disease, and avoid misdiagnosis.Methods:Clinical data of 8 adult NIID patients in the Hunan region were collected, and their clinical manifestations, cranial imaging, genetic testing, skin biopsy, and other characteristics were analyzed.Results:Among the 8 patients, 4 were males and 4 were females; The initial symptoms of 2 patients were dizziness, 2 were mental abnormalities, 2 were stroke like attacks, 1 was urinary incontinence, and 1 was limb tremor; Six patients experienced slow progression of the disease, while two patients experienced sudden progression after several years of slow progression; The GGC repeat amplification mutation in the 5′untranslated region of the NOTCH2NLC gene, as well as the lace like sign in the brain cortex medullary junction on diffusion-weighted imaging (DWI) and the presence of eosinophilic transparent inclusion bodies in the nucleus on skin biopsy, were helpful in diagnosing NIID.Conclusions:The clinical manifestations of NIID are highly heterogeneous, and some patients have rare initial clinical symptoms, which are prone to misdiagnosis and missed diagnosis. It is necessary to combine imaging, genetic testing, and skin biopsy to confirm the diagnosis; Some patients may experience sudden progression and poor prognosis after years of slow progression.

Objective:To quantitatively analyze infection prevention and control policy texts related to medical alliance, aiming to provide reference for further policy improvement.Methods:with the " medical alliance" and " infection prevention and control" as keywords, relevant policy documents issued from January 2015 to March 2023 were searched on the Chinese government website, the official website of the National Health Commission, and the Peking University law database. Content analysis method was used to quantitatively analyze policy texts from two dimensions: policy tools (supply oriented, environmental oriented, demand oriented) and systems theory (management, service, human resources, and financing systems as internal subsystems, while political, economic, social, and technological systems as external subsystems).Results:A total of 91 infection prevention and control policy documents related to medical alliance were included, and 199 codes were obtained. There were 114, 78, and 7 codes for environmental oriented, supply oriented, and demand oriented policy tools, respectively; among the demand oriented tools, there were only 1 code for government purchases, 1 code for price subsidies, and 5 codes for demonstration project sub tools, respectively. The internal subsystem had a total of 119 codes, with only 2 codes related to the fundraising system; and the external subsystem had a total of 80 codes, with the least 10 codes related to the technical system.Conclusions:The structure of infection prevention and control policy tools in China′s medical alliance needed to be optimized, and the application of demand oriented policy tools was insufficient. It is necessary to strengthen the use of pull tools such as government purchases, price subsidies, and demonstration projects. At the same time, it is necessary to improve the construction of internal and external systems, especially in terms of fundraising and technology systems, to enhance the overall effectiveness of the medical alliance′s infection prevention and control system.

Objective:To explore whether transjugular intrahepatic portosystemic shunt (TIPS) can improve the prognosis of esophagogastric variceal bleeding (EGVB) combined with sarcopenia in cirrhotic patients.Methods:A retrospective cohort study was performed. A total of 464 cases with cirrhotic EGVB who received standard or TIPS treatment between January 2017 and December 2019 were selected. Regular follow-up was performed for the long-term after treatment. The primary outcome was transplantation-free survival. The secondary endpoints were rebleeding and overt hepatic encephalopathy (OHE). The obtained data were statistically analyzed. The t-test and Wilcoxon rank-sum test were used to compare continuous variables between groups. The χ2 test, or Fisher's exact probability test, was used to compare categorical variables between groups. Results:The age of the included patients was 55.27±13.86 years, and 286 cases were male. There were 203 cases of combined sarcopenia and 261 cases of non-combined sarcopenia. The median follow-up period was 43 months. The two groups had no statistically significant difference in follow-up time. There was no statistically significant difference in transplant-free survival between the TIPS group and the standard treatment group in the overall cohort ( HR=1.31, 95% CI: 0.97-1.78, P=0.08). The TIPS patient group with cirrhosis combined with sarcopenia had longer transplant-free survival (median survival: 47.76 vs. 52.45, χ2=4.09; HR=1.55, 95 CI: 1.01~2.38, P=0.04). There was no statistically significant difference in transplant-free survival between the two kinds of treatments for patients without sarcopenia ( HR=1.22, 95% CI: 0.78~1.88, P=0.39). Rebleeding time was prolonged in TIPS patients with or without sarcopenia combination (patients without combined sarcopenia: median rebleeding time: 39.48 vs. 53.61, χ2=18.68; R=2.47, 95 CI: 1.67~3.65, P<0.01; patients with sarcopenia: median rebleeding time: 39.91 vs. 50.68, χ2=12.36; HR=2.20, 95 CI: 1.42~3.40, P<0.01). TIPS patients had an increased 1-year OHE incidence rate compared to the standard treatment group (sarcopenia patients: 6.93% vs. 16.67%, χ2=3.87, P=0.049; patients without sarcopenia combination: 2.19% vs. 9.68%, χ2=8.85, P=0.01). There was no statistically significant difference in the long-term OHE incidence rate between the two kinds of treatment groups ( P>0.05). Conclusion:TIPS can significantly prolong transplant-free survival compared to standard treatment as a secondary prevention of EGVB concomitant with sarcopenia in patients with cirrhosis. However, its advantage is not prominent for patients with cirrhosis in EGVB without sarcopenia.

Objective:To explore the role of serum pyrrole-protein-adduct (PPA) in evaluating the severity and predicting the anticoagulant efficacy in patients with pyrrolidine alkaloid-related hepatic sinusoidal obstruction syndrome (PA-HSOS).Methods:From April 2018 to December 2019, the data of 48 patients with PA-HSOS admitted and treated at Drum Tower Hospital, Affiliated Medical College of Nangjing University were collected, which included PPA level, portal vein velocity (PVV), ascites grading, PA-HSOS severity grading (according to the new severity grading criteria for suspected hepatic sinusoidal obstruction syndrome in adults by the European Society of Blood and Bone Marrow Transplantation and adjusted) and the outcome of anticoagulation. Patients with acute onset (onset of symptoms within 1 month after consuming pyrrolizidine alkaloid-containing plants) were taken as research subjects. The combination of PPA with PVV or with ascites classification of PA-HSOS severity assessment model was fitted by logistic regression, and the logit values of 2 combination models were calculated, the formula was logit 1=0.034×PPA(nmol/L)+ 0.055×PVV(cm/s)-3.287, logit 2=0.039×PPA(nmol/L)-2.712×ascites grade 2 (Yes=1, No=0)-0.388×ascites grade 3 (Yes=1, No=0)-0.899. The patients received initial anticoagulation therapy at Drum Tower Hospital, Affiliated Medical College of Nanjing University were selected as research subjects. The anticoagulant efficacy prediction model of combination of PPA with serum creatinine (SCR) and with hepatic venous pressure gradient (HVPG) was fitted by logistic regression, and the logit value was calculated, the formula was logit 3=0.013×PPA(nmol/L)+ 0.064×SCR (mol/L)+ 0.542×HVPG (mmHg, 1 mmHg=0.133 kPa)-16.005. The predictive value of PPA in evaluating the severity of PA-HSOS and anticoagulant efficacy was evaluated. Receiver operating characteristic curve analysis was performed for statistical analysis. Results:The serum PPA level of 48 patients was 10.81 nmol/L (3.91 nmol/L, 32.04 nmol/L). Among them, 33 cases (68.8%) were mild PA-HSOS, 3 cases (6.2%) were moderate PA-HSOS, no severe PA-HSOS case and 12 cases (25.0%) were very severe PA-HSOS. Among 23 patients received initial anticoagulant therapy at Drum Tower Hospital, Affiliated Medical College of Nanjing University and with complete data, 8 patients responded and survived, and 15 patients did not respond (5 patients died, 1 patient relieved after continue anticoagulant therapy, and 9 patients survived after switching to anticoagulant therapy and transjugular intrahepatic portosystemic shunt (TIPS) treatment). One patient without initial anticoagulant therapy, survived after TIPS treatment because of the progress of the disease. Area under the curve (AUC) of PPA to assess the severity of acute onset PA-HSOS was 0.75, 95% confidence interval ( CI) was 0.52 to 0.98 ( P=0.047). When PPA≥45.519 nmol/L, the specificity and sensitivity in evaluating severe and very severe PA-HSOS was 100.0% and 57.1%, respectively. AUC of combination of PPA and PVV to assess the severity of PA-HSOS was 0.77, 95% CI was 0.55 to 1.00 ( P=0.032). When the logit of combination model≥0.180, the specificity and sensitivity in evaluating severe and very severe PA-HSOS was 71.4% and 81.8%, respectively. AUC of combination of PPA and ascites grade (grade 1, 2 or 3) to assess the severity of PA-HSOS was 0.85, 95% CI was 0.63 to 1.00 ( P=0.005). When the logit of combination model≥0.347, the specificity and sensitivity in evaluating severe and very severe PA-HSOS was 85.7% and 92.0%, respectively. AUC of combination of PPA, SCR and HVPG to predict anticoagulation efficacy was 0.85, 95% CI was 0.69 to 1.00 ( P=0.009). When the logit≥0.393, the specificity and sensitivity in predicting anticoagulation efficacy was 62.5% and 91.7%, respectively. Conclusions:PPA can be used to assess the severity of acute onset PA-HSOS patients, and combined with ascites grading can significantly improve its efficiency. PPA combined with SCR and HVPG can better predict anticoagulant efficacy.
