Objective: In order to find out the prevalence and death of pneumoconiosis in Qingyuan City, to explore the regularity of pneumoconiosis and lay a foundation for the prevention and management of pneumoconiosis. Methods: In August to December 2019, the basic data of pneumoconiosis from 1949 to 2018 were obtained through the monitoring of death causes of residents, occupational disease management system, Guangdong population information system and other means. The reported cases of pneumoconiosis were followed up, and retrospective investigation was conducted to analyze the basic conditions, the length of service exposed to dust, the time of diagnosis, the type of disease, the stage and the combined status of tuberculosis of pneumoconiosis cases. Results: From 1949 to 2018, a total of 466 cases of new pneumoconiosis were reported in Qingyuan City, including 325 cases of death (69.74%) , 114 cases of survival (24.46%) and 27 cases of loss of follow-up (5.80%) . The cases were mainly concentrated in the age group of 40-89 years (80.04%, 373/466) . There were 411 male cases (88.20%) and 7 female cases (1.50%) . The median length of service exposed to dust was 10.7 (6.0, 16.0) years. The diagnosis time of pneumoconiosis cases was mainly from 1949 to 1986 (68.67%, 320/466) , and the death cases were mainly from 1949 to 1986 (82.77%, 269/325) . Silicosis was the main type of pneumoconiosis (398 cases, 85.41%) . 200 cases (42.92%) were diagnosed as stage I pneumoconiosis, 185 cases (39.69%) were stage II pneumoconiosis, 81 cases (17.38%) were stage III pneumoconiosis at the first diagnosis. 102 cases (21.89%) were pneumoconiosis with tuberculosis. The proportion of death and lost follow-up cases diagnosed as stage I pneumoconiosis for the first time was significantly lower than that of survival cases, and the proportion diagnosed as stage II pneumoconiosis and the complication rate of tuberculosis were significantly higher than those of survival cases (χ(2)=15.48, 11.29, 32.73, P<0.001) . Conclusion: Pneumoconiosis in Qingyuan City is mainly silicosis. The number of new cases has been increasing in the past decade, and the prevention and control situation is still severe. The comprehensive prevention and treatment of silica dust should be included in the focus of supervision of government functional departments.

Objective: To observe whether an Xingnaojing 醒脑静 injection could improve the prognosis of patients, by increasing rifampicin penetration through the blood-brain barrier. Methods: Patients with severe tuberculous meningitis were enrolled in this study. The concentrations of Xingnaojing in cerebrospinal fluid and blood in patients treated with Xingnaojing and control were determined by high performance liquid chromatography. The changes in cerebrospinal fluid and the improvement of clinical symptoms and signs, were evaluated two weeks after admission. The long-term prognosis of the patients in the two groups were evaluated by the Glasgow Outcome Scale (GOS). Results: The concentration of rifampicin in cerebrospinal fluid was significantly higher in the Xingnaojing group (1.77±0.17 μg/mL), than in the control group (1.27±0.16 μg/mL, p<0.05). The difference in concentration of rifampicin in the blood was not significant (P>0.05). The short-term effective rate of the Xingnaojing group was 92.5% (37/40), which was significantly higher than that of the control group (80%, 32/40, p<0.05). After 6 months, 75% (30/40) of the Xingnaojing group had good prognosis according to the GOS score, whereas that of the control group was 50% (20/40) showing significantly better long-term treatment effect of the Xingnaojing group compared to the control group (P<0.05). Conclusion: Xingnaojing injection improved rifampicin penetration into the central nervous system. The increase in rifampicin concentration in cerebrospinal fluid improved outcomes in patients with severe tuberculous meningitis.

Objective: Study of the results and the degree on occupational noise-induced deafness in-to the different high frequency hearing threshold weighted value, in order to provide theoretical basis for the re-vision of diagnostic criteria on occupational noise-induced deafness. Methods: A retrospective study was con-ducted to investigate the cases on the diagnosis of occupational noise-induced deafness in Guangdong province hospital for occupational disease prevention and treatment from January 2016 to January 2017. Based on the re-sults of the 3 hearing test for each test interval greater than 3 days in the hospital, the best threshold of each frequency was obtained, and based on the diagnostic criteria of occupational noise deafness in 2007 edition, Chi square test, t test and variance analysis were used to measure SPSS21.0 data, their differences are tested among the means of speech frequency and the high frequency weighted value into different age group, noise ex-posure group, and diagnostic classification between different dimensions. Results: 1. There were totally 168 cases in accordance with the study plan, male 154 cases, female 14 cases, the average age was 41.18 ±6.07 years old. 2. The diagnosis rate was increased into the weighted value of different high frequency than the mean value of pure speech frequency, the weighted 4 kHz frequency increased by 13.69% (χ²=9.880, P=0.002) , 6 kHz increased by 15.47% (χ²=9.985, P=0.002) and 4 kHz+6 kHz increased by15.47% (χ²=9.985, P=0.002) , the difference was statistically significant. The diagnostic rate of different high threshold had no obvious differ-ence between the genders. 3. The age groups were divided into less than or equal to 40years old group (A group) and 40-50 years old group (group B) , there were higher the diagnostic rate between high frequency weighted 4 kHz (A group χ²=3.380, P=0.050; B group χ²=4.054, P=0.032) , weighted 6 kHz (A group χ²=6.362, P=0.012; B group χ²=4.054, P=0.032) , high frequency weighted 4 kHz+6 kHz (A group χ²=6.362, P=0.012; B group χ²=4.054, P=0.032) than those of speech frequency average value in the same group on oc-cupational noise-induced deafness diagnosis rate, the difference was statistically significant. There was no sig-nificant difference between age groups (χ²=2.265, P=0.944) . 4. The better ear's mean value of pure speech fre-quency and the weighted values into different high frequency of working years on each group were compared, working years more than 10 years group was significantly higher than that of average thresholds of each frequen-cy band in 3-5 group (F=2.271, P=0.001) , 6-10 group (F=1.563, P=0.046) , the difference was statistically significant. The different high frequency weighted values were higher than those of the mean value of pure speech frequency, and the high frequency weighted 4 kHz+6 kHz had the highest frequency difference, with an average increase of 2.83 dB. 5. The diagnostic rate into weighted different high frequency was higher in the mild, moderate and severe grades than in the pure speech frequency. In the comparison of diagnosis for mild occupational noise-induced deafness, in addition to the weighted 3 kHz high frequency (χ²=3.117, P=0.077) had no significant difference, the weighted 4 kHz (χ²=10.835, P=0.001) , 6 kHz (χ²=9.985, P=0.002) , 3 kHz+4 kHz (χ²=6.315, P=0.012) , 3 kHz+6 kHz (χ²=6.315, P=0.012) , 4 kHz+6 kHz (χ²=9.985, P=0.002) , 3 kHz+4 kHz+6 kHz (χ²=7.667, P=0.002) were significantly higher than the diagnosis rate of the mean value of pure speech frequency. There was no significant difference between the two groups in the moderate and se-vere grades (P>0.05) . Conclusion Bring into different high frequency hearing threshold weighted value in-creases the diagnostic rate of occupational noise-induced deafness, the weighted 4 kHz, 6 kHz and 4 kHz+ 6 kHz high frequency value affects the result greatly, and the weighted 4 kHz+6 kHz high frequency hearing threshold value is maximum the effect on occupational noise-induced deafness diagnosis.

Objective:Astragalus polysaccharide (APS) was used in combination with ionizing radiation (IR) to investigate the mechanism of APS on the radiosensitivity of human nasopharyngeal narcinoma CNE-1 cells and the epithelial-mesenchymal transition (EMT). Method:Cell counting kit-8 (CCK-8) was used to detect the cytotoxicity of different concentrations of APS (0，6.25，12.5，25，50，100，200 g·L^-1) on CNE-1 cells. Colony formation assay was used to calculate the survival fraction (survival fraction, SF) of CNE-1 cells treated with 12.5 g·L^-1 APS combined with different radiation doses (0，2，4，6 Gy). The linear quadratic equation mathematical model (LQ) was used to draw the radiosensitivity curve according to SF value. Cell scratch and transwell chamber test were used to detect the migration and invasion ability of cells in each group. The apoptosis of cells in each group was detected by flow cytometry, Western blot was used to detect the expressions of EMT markers, apoptosis markers and protein kinase B/extracellular regulated protein kinases (Akt/ERK) pathway proteins in each group. Result:The results of colony formation assay and radiosensitivity curve showed that the combination of non-toxic dose of 12.5 g·L^-1 APS and radiation dose of 4 Gy could significantly increase the radiosensitivity of CNE-1 cells. Compared with blank group and IR group, APS combined with IR could significantly inhibit the migration and invasion of CNE-1 cells (P<0.05), and increase the rate of apoptosis (P<0.05). In addition, compared with the blank group and the IR group, APS combined with IR could significantly down-regulate the expressions of N-cadherin, p-Akt and p-ERK, and significantly up-regulate the expressions of E-cadherin, Bax and Caspase-3 (P<0.05). Conclusion:APS combined with IR can inhibit the migration and invasion of CNE-1 cells, and increase the apoptosis induced by radiotherapy, which may be related to the inhibition of EMT and Akt/ERK pathway.
