Objective To study biologic effect of high radon exposure in non-uranium miners by measurements of serum levels of 1L-2, IL-6 and TNF-u and study on their gene polymorphism. Methods Serum levels of IL-2, IL-6 and TNF-αin the miners selected from a Yunnan-based copper mine were measured by ABC-ELISA. TNF-α (-308,G→A) genotypes were identified by RFLP-PCR, IL-2 (-330, T→G) genotypes by sequence analysis. Results Compared the miners with its control group, there were no statistical significance of the concentrations of serum IL-2 (F=0.71, P>0.05), IL-6 (F=1.09, P>0.05) and TNF-α(F=0.95,P>0.05). Frequencies of IL-2 (-330, T→G) genotypes (X2=0.02, P>0.05) and TNF-α(-308, G→A) genotype (x2= 2.21, P>0.05) were shown no statistical significance too. Conclusions Compared with the control group, concentrations of serum IL-2, IL-6 and TNF-n in miners working in the copper mine was lower, frequencies of genotypes of TNF-o (-308,A/A) was higher in the miners. But all the differences were not statistical significant.

There were significant differences between the two groups ( t value was 70.093, 72.855, 31.859 respectively, all P<0.01). The ScvO 2, NT-pro BNP and lactate clearance rate in the early treatment group were (71.66±5.45)%, (1 698.36±1 032.98) ng/L and (30.12±2.29)%, respectively at 48 hours after IABP, and those in the late treatment group (66.03±4.61)%, (2 898.43±1 383.29) ng/L and (20.47±1.92)%.There were significant differences between the two groups ( t value was 38.279, 34.379 respectively, all P<0.01). The incidence of complications were 18% (6/33) and 41.94%(13/31) in the early treatment group and the late treatment group.There was significant difference between the two groups( P=0.038). Conclusion:Early use of IABP treatment can improve the patients′ hemodynamic and serological indicators, reduce the patient′s mechanical ventilation time, IABP time, ICU monitoring time and complications.

Objective:To improve the accuracy of the coding of occupational radiation diseases in China, to provide standardized basis for the research on the management of such diseases as well as the informatization management of medical records and the formulation of relevant policies, and to improve the level of prevention and control.Methods:According to the nomenclature and disease characteristics of occupational radiation diseases in China, the diseases were coded by ICD-10 coding rules.Results:The system of occupational radiation diseases in China is the sum of all kinds of diseases caused by ionizing radiation, which is different from the common clinical symptom. The coding of such diseases must be based on the location, clinical manifestations, pathological changes, and other characteristics.Conclusions:The accuracy of occupational radiation diseases coding directly affects the accuracy of disease statistical data. Standardizing the coding of these diseases is a very necessary supplement to the system of occupational radiation diseases in China.

Objective:
To establish a multiplexed immunoassay for detection of IgG antibodies against viral hemorrhagic fever epidemic in Africa.
Methods:
The recombinant antigens of hemorrhagic fever viruses (HFVs) epidemic in Africa were expressed and purified, and then coupled with the fluorescent microspheres. The coupling effects were evaluated by monoplexed detection of rabbit immune sera. Blood specimens were collected from people from Africa with fever, and multiplexed detection of IgG antibodies to HFVs was performed. Comparison of multiplexed assay and ELISA was performed by paired χ2 test using SPSS software.
Results:
Both the purity and concentration of HFVs recombinant antigen met the standards for coupling and detection, and the antigens were successfully coupled with fluorescent microspheres. Seventy-eight sera samples of people from Africa with fever were multiplex detected. Among these, one was tested positive for LASV-specific IgG, one was tested positive for LUJV-specific IgG, 4 were tested positive for DENV-specific IgG and 6 tested positive for YFV-specific IgG. There was no statistically significant difference compared with ELISA, and the two method were highly correlated.
Conclusions
A multiplexed luminex-based immunoassay for detection of IgG antibodies to viral hemorrhagic fever epidemic in Africa was established, which laid the foundation for the differential diagnosis.

Objective:To evaluate the radiation shielding performance for a novel self-shielded ZAP-X radiotherapy system used for intra-cranial and neck treatments. The present evaluation was performed according to the relevant Chinese national standards and the clinical placement of the radiotherapy system in an unshielded treatment room.Methods:The radiation source of the ZAP-X was a 3 MV linear accelerator. A total of 33 detection sites were selected surrounding the self-shielded system at 1.3, 2.3 and 3.3 m away from the periphery of the equipment. The maximum ambient dose equivalent rate in each irradiation condition was measured accordingly. A commonly used clinical treatment plan was selected to simulate the treatment process. During the delivery of this treatment plan, the cumulative doses of these 33 sites were measured, separately. The applicable current radiation protection standard for radiotherapy in China was chosen to evaluate the radiation shielding performance of the system.Results:According to the measurement result of the ambient dose equivalent rates along the aforementioned perimeter lines, a suggestion was put forward to redefine the existing 1 m controlled area by determining the distance at which the instantaneous dose rate of 10 μSv/h will not be exceeded. This is to meet the requirements of the Chinese standard GBZ 121-2020.Conclusions:According to the existing Chinese national radiation protection standards, the self-shielded radiotherapy system in the unshielded treatment room has the clinical applicability in China. But for such a novel self-shielded system, the corresponding performance testing and radiation protection standards shall be formulated.
