One case of rare giant mucous cyst of nasal sinus that implicated frontal, ethmoid and maxillary sinus was in our hospital. The patient manifested mainly slowly developing swelling and pain of cheek, exophthalmos and visual impairment. The image studies indicated cyst of nasal sinus, including frontal, ethmoid, and maxillary sinuses. The clinical diagnosis was cyst of frontoethmomaxillary sinus.

Objective To explore the significance of the relative proteins in thrombin sensitive protein(TSP-1) and nuclear factor kappa B (NF-κB) signal pathways by detecting their expressions in different phases of hemangioma and the relations between them and microvessel density(MVD).Methods Forty cases with hemangioma were randomly selected and divided into proliferative group(n =21) and involutional group(n =19) according to Mulliken standard.The expressions of TSP-1,CD36,p59fyn,Caspase-3,p38MAPK,NF-κBp65,p-IκBα,p-IKKβ,VEGF and CD34 in endothelial cells were detected by immunohistochemistry.The relevance between the proteins in TSP-1 and NF-κB signal pathways and MVD were compared and analyzed respectively.Results The expressions of TSP-1,CD36,p59fyn,Caspase-3,p38MAPK in proliferative hemangioma were all lower than those in involutional hemangioma (F=32.582,47.575,11.645,18.824,13.140;P =0.000,0.000,0.002,0.000,0.001).Conversely,the expressions of NF-κBp65,p-IκBα,p-IKKβ,VEGF in proliferative hemangioma were higher than those in involutional hemangioma(F =7.807,6.323,5.988,4.216;P =0.009,0.018,0.021,0.049).Meanwhile,MVD were different between the two groups(F =7.256,P =0.012).The expressions of TSP-1,CD36,p59fyn and MVD showed a negative relationship(rs =-0.420,-0.519,-0.388;P =0.021,0.003,0.034).Conversely,the expressions of NF-κBp65,pvIκBα,VEGF and MVD showed a positive relationship(rs =0.666,0.611,0.515;P =0.000,0.000,0.004).The expression of TSP-1 and NF-κBp65 showed a negative relationship (rs =-0.413,P =0.023).Conclusions TSP-1 signal pathway and NF-κBp65 signal pathway may be interactive in evolution of infantile hemangioma,which has a potential role by effecting the progress of angiogenesis.

Objective To investigate the current status of radiation protection in non-medical radiation workplaces in Yantai, China, and to provide a scientific basis for occupational health management in non-medical radiation workplaces. Methods Non-medical radiation workplaces in Yantai were investigated using a questionnaire survey in 2022, including radiation source term, occupational health examination, personal dose monitoring, personal protective equipment, and radiation protection testing workplaces. Data were entered by a double-entry method and then analyzed. Results There were 56 non-medical radiation workplaces in Yantai, covering manufacturing, nonferrous metal ore mining, nuclear power plant, transportation, and technical services. There were 0 Class I radiation device, 150 Class II radiation devices, and 10 Class III radiation devices; there were 80 Class I radiation sources, 16 Class II radiation sources, 14 Class III radiation sources, 62 Class IV radiation sources, and 135 Class V radiation sources. There were 998 radiation workers, with an occupational health examination rate and personal dose monitoring rate of 98.3%. Among the 56 non-medical radiation workplaces, 47 (83.9%) were equipped with radiation protection monitoring instruments, 24 (51.1%) workplaces had verified the radiation protection monitoring instruments, with 2017 personal dose monitoring instruments and 2327 personal protective equipment in place, 42 (75%) workplaces carried out occupational health assessments, 44 (78.6%) workplaces carried out self-detection, and 53 (94.6%) workplaces carried out entrusting detections (monitoring pass rate: 100% [53/53]). The declaration rate of occupational hazard items was 87.5% (49/56). Conclusion There is still a gap between the current status and the requirements in the national regulations and standards regarding radiation protection in non-medical radiation workplaces. Therefore, the supervision and management of non-medical radiation workplaces should be further strengthened, especially the configuration and verification of radiation protection monitoring instruments.
