With the development and utilization of nuclear energy, the safe operation of nuclear facilities has become a social issue of great concern. China attaches great importance to nuclear emergency plan and the construction of legal, institutional, and mechanism systems. Among them, the emergency preparedness and response of airborne monitoring for nuclear emergency is one of the important components of the national nuclear emergency system. The technology system of airborne monitoring for nuclear emergency is being developed and combines the advantages of manned aircraft and unmanned aerial vehicle (UAV) airborne monitoring. In recent years, UAVs with different loads and types have been developed, with diversified sizes and types of detectors carried by UAVs. The research on UAV airborne monitoring techniques for nuclear emergency has been continuously deepened and improved, and the technical system of airborne monitoring for nuclear emergency has been developed at the same time. The construction of UAV airborne monitoring technology system for nuclear emergency is discussed from the perspectives of monitoring equipment and technology, emergency response plan, emergency monitoring and evaluation, monitoring standards, emergency personnel, emergency support, and training and exercise. The UAV is a rapidly developing aircraft. With the continuous improvement in UAV performance and the continuous innovation and development of nuclear emergency airborne monitoring technology, the UAV airborne monitoring technology system for nuclear emergency will be constantly improved and developed towards networking, intelligence, and standardization.

BACKGROUND: To determine the prevalence and prognostic impact of hepatopulmonary syndrome (HPS) in patients with unresectable hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE). METHODS: Fifty-four patients with unresectable HCC undergoing TACE between December 2014 and December 2015 were prospectively screened for HPS and were followed up for a maximum of 2 years or until the end of this prospective study. RESULTS: Nineteen of the 54 (35.2%) patients were considered to have HPS, including one (5.3%) with severe HPS, nine (47.4%) with moderate HPS, and nine (47.4%) with mild HPS. The median overall survival (OS) was 10.1 (95% confidence interval [CI], 3.9-16.3) months for patients with HPS and 15.1 (95% CI, 7.3-22.9) months for patients without HPS, which is not a significant difference ( P  = 0.100). The median progression-free survival was also not significantly different between patients with and without HPS (5.2 [95% CI, 0-12.8] vs. 8.4 [95% CI, 3.6-13.1] months; P  = 0.537). In the multivariable Cox regression analyses, carbon monoxide diffusing capacity (hazard ratio [HR] = 1.033 [95% CI, 1.003-1.064]; P  = 0.028) and Child-Pugh class (HR = 1.815 [95% CI, 1.011-3.260]; P  = 0.046) were identified to be the independent prognostic factors of OS. CONCLUSION Mild or moderate HPS is common in patients with unresectable HCC undergoing TACE, but it does not seem to have a significant prognostic impact.

Objective: To investigate the effect of elective neck dissection on the 5-year survival rate of patients with early oral squamous cell carcinoma. Methods: The data of 100 patients with early oral squamous cell carcinoma (cT1-2N0M0) were retrospectively analyzed. In 61 cases, the primary tumor was subjected to elective neck dissection (END). Neck observation and follow-up (NOF) were performed in 39 cases with enlarged resection of primary lesions. Clinicopathological data such as pT staging, pathology classification,the rate of cervical lymph node metastasis and the 5-year survival rate of the patients were statistically analyzed. Results: The 5-year survival rates of the END and NOF groups were 86.9% and 69.2%, respectively, and the difference was statistically significant (P=0.028). END treatment was significantly better than NOF in controlling cervical lymph node metastasis in early oral squamous cell carcinoma (P=0.009). After stratified analysis of histopathological features, the 5-year survival rate of patients with pathological T2 (pT2) stage OSCC in the END group was significantly higher than that in the NOF group (P=0.020). The 5-year survival rate of patients with moderate and poorly differentiated pathological grade OSCC in the END group was significantly higher than that in the NOF group (P=0.013). Conclusion END is effective for the management of the cervical lymph node metastasis rate in early OSCC patients. For patients with pT2 stage or low differentiation pathological grade, active END can significantly improve the 5-year survival rate.

Androgen deprivation therapy (ADT) combined with abiraterone and prednisone.for metastatic hormone sensitive prostate cancer (mHSPC) is proved effective in many researches, but it is not verified in china. We present the case of a 62-year-old man who was referred to our hospital for high-risk mHSPC with the main symptoms of dysuria and weak stream. the level of prostate-specific antigen (PSA) was elevated, and the results of biopsy, magnetic resonance and PET-CT showed prostate cancer with multiple lymph node metastases to the right scapula and right pubic bone (T 3bN 1M 1b). The patients were treated with the combination of ADT plus abiraterone and prednisone. After treatment, the level of PSA and testosterone returned to normal and were well-controlled.

Objective:To explore the performance of the commonly used whole blood C-reactive protein (CRP) detection systems and give related recommendation on the performance requirements of detection systems.Methods:A total of 7 540 venous blood samples from 26 maternal, child and children′s hospitals were collected to conduct this multi-center study on the analytical performance of 5 commonly used whole blood CRP detection systems from March to April in 2019. The blank check, carryover, repeatability, intermediate precision, linearity, sample stability, influence of hematocrit/triglyceride/bilirubin, comparison with SIEMENS specific protein analyzer and trueness were evaluated. The 5 systems included BC-5390CRP autohematology analyzer, AstepPLUS specific protein analyzer, Ottoman-1000 Automated Specific Protein POCT Workstation, i-CHROMA Immunofluorometer equipment Reader and Orion QuikRead go detecting instrument. The 5 systems were labeled as a, b, c, d and e randomly.Results:Within the 5 systems, all values of blank check were less than 1.00 mg/L, the carryovers were lower than 1.00%. The repeatability of different ranges of CRP concentrations including 3.00-10.00, 10.00-30.00 and>30.00 mg/L were less than 10.00%, 6.00% and 5.00%, respectively, and the intermediate precision was less than 10.00%. The linearity correlation coefficients of the 5 systems were all above 0.975, while the slope was within 0.950-1.050. Whole blood samples were stable within 72 hours both at room temperature (18-25 ℃) and refrigerated temperature (2-8 ℃). The CRP results were rarely influenced by high triglyceride or bilirubin, except for the immmunoturbidimetric test based on microparticles coated with anti-human CRP F(ab) 2 fragments. When triglyceride was less than 15.46 mmol/L, the deviation of CRP was less than 10.00%. When bilirubin was less than 345.47 μmol/L, the deviation of CRP was less than 10.00%. CRP was more susceptible to Hct on the systems without Hct correction. The deviation of CRP between different Hct dilution concentration and 40% dilution concentration can reach as high as 67.48%. The correlation coefficients ( r) of 5 systems were all more than 0.975 in the range of 0-300.00 mg/L compared with Siemens specific protein analyzer. All systems passed the trueness verification using the samples with specified values of 12.89 and 30.60 mg/L. Conclusion:The performance of 5 systems can basically meet the clinical needs, but it is suggested that the whole blood CRP detection system without automatic Hct correction should be modified manually.

Breast cancer is the most common cancer for Chinese women. Early screening is the best way to improve the rates of early diagnosis and early treatment of breast cancer. The peak ages of breast cancer in Chinese women are obviously different from those in the European and American countries. It is imperative to develop a guideline for breast cancer screening that is suitable for Chinese women. Based on the analysis and summary of breast cancer screening data in China, and the latest guidelines and consensus on breast cancer screening in Europe, the United States and East Asia, China Anti-Cancer Association and National Clinical Research Center for Cancer (Tianjin Medical University Cancer Institute and Hospital) has developed a population-based guideline for breast cancer screening in Chinese women. This guideline has provided detailed recommendations on the screening starting age, screening modalities, and screening interval in Chinese women with average risk and high risk of breast cancer, respectively. This article aims to interpret the above guideline, providing references for professionals in breast cancer screening.
