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.

Multimorbidity has emerged as a critical global public health challenge, necessitating effective management strategies. In Heilongjiang Province, a cold north region in China with a high prevalence of multimorbidity, healthcare disparities, uneven resource distribution, and inadequate chronic disease control remain pressing issues. Driven by national policies on family physician contracting and regional demands for chronic disease management, this study established a "hospital-community general practitioner co-management" model utilizing a mobile-based digital platform. This model integrates hospital-based general practitioners into primary care teams to optimize resource allocation and enhance multimorbidity management. The initiative aims to explore pathways for improving healthcare system reform and strengthening the chronic disease prevention framework in the region.

Objective:To investigate the efficacy and safety of dupilumab in the treatment of elderly patients (≥ 60 years old) with atopic dermatitis (AD), with particular attention paid to rare adverse reactions.Methods:A single-center retrospective analysis was conducted on data collected from 281 elderly AD patients who received the standard regimen of dupilumab at the Department of Dermatology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from January 2020 to May 2024. Clinical characteristics such as gender, disease duration, skin lesion manifestations, and itch severity were analyzed. Changes in skin lesions and itch severity, as well as related adverse events were recorded during the follow-up period of 0 - 16 weeks. The efficacy and safety of dupilumab in the treatment of elderly AD patients were evaluated.Results:Among the 281 elderly AD patients, 214 were males (76.16%) and 67 were females (23.84%), with the age being 71.13 ± 7.91 years and the age at onset being 59.92 ± 15.72 years. The disease duration ( M[ IQR]) was 5.00 (13.00) years. After standard-regimen dupilumab treatment, the improvement rates of clinical outcome indicators SCORing Atopic Dermatitis (SCORAD) and pruritus numerical rating scale (NRS) scores gradually increased. At week 16, the improvement rates of SCORAD and NRS scores ( M[ IQR]) reached the maxima of 72.37% (23.89%) and 75.00% (29.72%), respectively. The overall incidence of adverse events was relatively low, with only 16 patients (6.05%) reporting adverse events. Common adverse reactions such as conjunctivitis (2 cases, 0.71%) and facial erythema (1 case, 0.36%) were mild and well-tolerated. Phenotype switching occurred in 10 cases (3.56%) . Conclusion:Dupilumab was an effective and safe treatment for elderly AD, but phenotype switching may occur.

Objective:To analyze the latent prevalence of hepatitis B and type 2 diabetes and their correlation through an observational study.Methods:This study used a case-control design. The cases with diabetes were recruited through the diabetes management system and village doctors, while the controls without diabetes were screened from volunteers recruited by village health clinics. Capillary blood samples were collected from the study participants for the measurement of real-time blood glucose level, and venous blood samples were taken from them for the detections of HBV serological markers. Firth logistic regression model was used to fit the relationship between HBsAg positive status and diabetes status.Results:The study included 1 218 diabetes patients, 62 patients with impaired fasting glucose and 491 cases without diabetes. In the cases without diagnosis of diabetes, 11.15% had impaired fasting blood glucose and 4.43% had diabetes. Among those who reported no or unknown diagnosis of hepatitis B, 1.73% were positive for HBsAg, while 18.80% were positive for both HBV core antibody and surface antibody, indicating latent infection of hepatitis B virus. In the non-diabetes group, 0.81% reported hepatitis B history, and in the diabetes group, 2.76% reported hepatitis B history. After adjustment, the HBsAg positive rate was higher in the diabetes group ( OR=2.90, 95% CI: 1.21-6.91). Conclusions:Both diabetes and hepatitis B exhibited a high degree of latent prevalence. The HBsAg positive rate was significantly higher in those with diabetes than in those without diabetes, indicating a potential correlation. These findings highlighted the importance of strengthened screening and management of comorbidities.

Objective:Exploration of the immunogenicity and persistence of three different immunization regimens of hepatitis B vaccines in diabetic patients.Methods:Participants with diabetes and non-diabetic individuals were recruited from study sites and assigned to different vaccination regimens: the diabetic group (①D60Yeast0-1: received 60 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-month schedule; ②D20Yeast0-1-6: received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule; ③D20CHO0-1-6: received 20 μg Chinese hamster ovary (CHO) cell-derived recombinant HBV vaccine on a 0-1-6-month schedule) and the non-diabetic group (ND20Yeast0-1-6: non-diabetic individuals received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule). Venous blood samples were collected at 1,12, and 48 months post-full vaccination to measure anti-HBs levels. Differences in immunogenicity between diabetic and non-diabetic groups, as well as among diabetic subgroups, were analyzed.Results:This study enrolled a total of 564 subjects. In the D20CHO0-1-6 group, the seroconversion rate decreased from 90.72% (95% CI: 84.84%-96.60%) at 1 month to 74.23% (95% CI: 65.37%-83.08%) at 48 months, and the antibody geometric mean concentration (GMC) decreased from 676.08 (95% CI: 389.05- 1 148.20) mIU/ml at 1 month to 33.11 (95% CI: 23.44-46.77) mIU/ml at 48 months. In the D20Yeast0-1-6 group, the seroconversion rate declined from 93.81% (95% CI: 89.29%-98.32%) at 1 month to 63.72% (95% CI: 54.71%-72.72%) at 48 months, with antibody GMC dropping from 630.96 (95% CI: 407.40-954.99) mIU/ml to 25.70 (95% CI: 17.78-38.02) mIU/ml over the same period. For the D60Yeast0-1 group, seroconversion rate fell from 82.03% (95% CI: 75.29%-88.77%) to 56.25% (95% CI: 47.54%-64.96%), and antibody GMC decreased from 81.28 (95% CI: 51.29-128.82) mIU/ml to 15.49 (95% CI: 11.75-20.89) mIU/ml between 1 and 48 months. The ND20Yeast0-1-6 group (non-diabetic control) exhibited a higher initial seroconversion rate of 97.56% (95% CI: 94.80%- 100.00%) at 1 month, but it still declined to 76.42% (95% CI: 68.82%-84.03%) at 48 months, with antibody GMC decreasing from 1 318.30 (95% CI: 912.01- 1 905.50) mIU/ml to 34.67 (95% CI: 25.12-47.86) mIU/ml. Multivariate analysis on factors influencing the GMC of antibodies revealed statistically significant differences in antibody GMC between the D20Yeast0-1-6 group and ND20Yeast0-1-6 group at 12 months (a OR=0.73, 95% CI: 0.58-0.93) and 48 months (a OR=0.79, 95% CI: 0.63-0.99) post-vaccination (all P<0.05). As for the diabetic population, when compared with the D20Yeast0-1-6 group, the D60Yeast0-1 group also showed statistically significant differences in antibody GMC at 12 months (a OR=0.57, 95% CI: 0.44-0.74) and 48 months (a OR=0.60, 95% CI: 0.47-0.76)(all P<0.05). Conclusions:The seroconversion rate and antibody GMC gradually decreased over time (1, 12, and 48 months) in the four groups. Diabetic patients showed poor immunogenicity and persistence to hepatitis B vaccines. The immunogenicity and persistence of hepatitis B vaccination in diabetic patients were associated with vaccine type, antigen dose, and vaccination regimen. The CHO cell-recombinant hepatitis B vaccine demonstrated better performance in terms of immunogenicity and persistence among the diabetic population.

The study was a prospective observational study. A total of 24 patients who underwent maintenance hemodialysis (MHD) at Haidian Hospital in Beijing from May 2024 to June 2024 were included as the study subjects. The safety and efficacy of a new single-needle dialysis in MHD patients were evaluated. The reasons for using single-needle dialysis included waiting for the maturity of internal fistula(7 cases, 29.17%), autogenous arteriovenous fistula thrombosis occurred (6 cases, 25.00%), puncture difficulty occurred (7 cases, 29.17%), and pain sensitivity or elderly (4 cases, 16.67%). The results showed that the average blood flow was (155.65±5.90) ml/min, total blood volume was (35.92±2.65) L during single-needle dialysis. One patient had slight puncture leakage, and the puncture success rate was 95.83%. Relevant indicators of dialysis adequacy showed that the average urea clearance (Kt/V) was 0.90±0.42, urea reduction ratio was 58.31%±7.93%, and online real-time Kt/V monitoring average value was 0.98±0.55. The results suggest that the application of the new improved single-needle dialysis mode in MHD patients is safe and effective.

Objective:To investigate the clinicopathological features, immunophenotype and prognosis of SWI/SNF complex-deficient sinonasal carcinomas.Methods:The clinicopathological, immunohistochemical profiles of 13 SWI/SNF complex-deficient sinonasal carcinomas diagnosed at Xuanwu Hospital, Beijing, China between Januay 2019 and December 2024 were reviewed and followed up.Results:The patients′ ages ranged from 33-81 years, median 59.0 (41.5, 64.5) years, including 10 males and 3 females. Imaging findings showed space-occupying lesions in the nasal cavity and sinuses. Microscopically, tumors predominantly exhibited invasive growth in medium-to-large nests or sheets, with relatively uniform morphology, mainly basaloid and/or small cells, while one recurrent case displayed epithelioid morphology. Focal necrosis was observed in 7 cases. Immunohistochemical results showed loss of SMARCA4/BRG1 in 7 cases, loss of SMARCB1/INI1 in 6 cases, and concurrent loss of SMARCA2 in 5 cases. CKpan was expressed to varying extent in all cases, 10 cases were EMA positive, and 5 cases were partially positive for p63/p40. Among neuroendocrine markers, 10 cases showed focal expression of syn or CgA. The Ki-67 proliferation index ranged from 40% to 90%. PD-L1 staining showed combined positive score (CPS) was ≥1 in 3 SMARCB1-deficient cases (CPS ranging from 2 to 3) and CPS <1 in the other 10 cases. Among the 13 patients, 2 were lost to follow-up, 6 died (postoperative survival: 1-25 months), and 5 remained alive, with the longest survival time of 130 months (follow-up range, 8-130 months).Conclusions:SWI/SNF complex-deficient sinonasal carcinoma is a rare undifferentiated malignancy in the head and neck, characterized by distinct pathological and molecular genetic features. SMARCA4-deficient and SMARCB1-deficient carcinomas both exhibit basaloid or small cell-like morphology. Compared to SMARCB1-deficient carcinomas, SMARCA4-deficient carcinomas show reduced expression of squamous cell markers but increased expression of neuroendocrine markers. The positive PD-L1 staining is more likely present in SMARCB1-deficient carcinomas than SMARCB4-dificient ones. Co-loss of SWI/SNF and SMARCA2 correlates with poorer prognosis. Comprehensive evaluation of histopathology, immunohistochemistry, and molecular genetics is critical for accurately diagnosing this rare entity.

Objective:To investigate the clinicopathological characteristics, immunophenotype and differential diagnosis of atypical forms of microglandular hyperplasia of the cervix (AMGH).Methods:A total of 29 cases of AMGH diagnosed at the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China from January 2010 to December 2024 were analyzed. Relevant clinical and pathological data of the patients were collected using the electronic medical record system and medical records copied from the outside hospitals. The patients were followed up.Results:Among the 29 cases, 28 were consultation cases, 22 (79%) of the 28 cases were considered as glandular neoplastic lesions by the original institutions. The nature of the lesion was uncertain in 1 case, the diagnosis was suspicious for AMGH in another 1 case, and only 4 cases were clearly diagnosed as AMGH. The median age of the 29 patients was 44 (43, 48) years. Eighteen (62%) of the 29 cases presented as cervical polyp. Twelve of the 16 tested cases were negative for human papillomavirus. The pathological presentation was complex and diverse, including solid, trabecular, cribriform, and papillary patterns, forming pseudo-invasive structures. The glandular epithelium and proliferating reserve cells had diverse morphologies, which presented with abundant eosinophilic cytoplasm or clear cytoplasm. Signet-ring or hobnail cells were also seen. The nuclear atypia was mild, with 0-7 mitotic figures per 10 HPF. Immature squamous metaplasia was noted. The stroma showed edema, myxoid change and hyaline degeneration, accompanied by infiltration of acute and chronic inflammatory cells. Immunohistochemistry demonstrated that p16 was negative in 8/16 of the cases or patchy positive in the other 8/16, Ki-67 positive rate was less than 10% in all 16 cases, p53 was wild phenotype (9/9), and carcinoembryonic antigen was negative in 4/5 cases and focally positive in 1/5 cases, while p63 was positive in 6/9 of the tested cases.Conclusions:AMGH is a benign non-neoplastic lesion of the cervical glands. Half of the cases occur in perimenopausal or postmenopausal women, often presenting as polypoid hyperplasia or localized cervical thickening/elevation with a friable, fragile texture. Microscopically, it may show a pseudoinvasive pattern, making it prone to misdiagnosis as a malignant lesion. Thus, differentiation from cervical adenocarcinoma, clear cell carcinoma and microglandular endometrioid carcinoma is required. Integration of clinical history, immunohistochemistry and molecular testing may aid in the differential diagnosis.
