Objective: To analyze the epidemiological characteristics of pneumoconiosis in Qinghai Province from 2011 to 2020, and to provide a basis for the formulation of prevention and control strategy. Methods: In April 2021 , the cases of pneumoconiosis were monitored by the Occupational Disease and Health Hazard Factors Monitoring Information System in Qinghai Province from 2011 to 2020. The distribution of pneumoconiosis, the composition of diseases and the working years exposed to dust were analyzed. Results: All 1026 cases of pneumoconiosis were newly diagnosed in Qinghai Province from 2011 to 2020, silicosis and coal worker pneumoconiosis were the main diseases (78.36% ,804/1026). Stage Ⅰ pneumoconiosis were 484 (47.17%,484/1026) cases. 359 (34.99%,359/1026) cases, 315 (30.70%,315/1026) cases and 252 (24.56%, 252/1026) cases had been diagnosed respectively in Xining City, Haidong City and Haixi Prefecture; 628 (61.21%,628/1026) cases and 418 (40.74%, 418/1026) cases engaged in mining industry and large-sized enterprise, respectively. The working years exposed to dust in silicosis cases were shorter than that in coal worker pneumoconiosis and other pneumoconiosis (P <0.05). Conclusion: The pneumoconiosis area and industry focus in Qinghai Province is obvious. The supervision and adninistration of small and micro scale employers should be strengthened to protect the health rights and interests of workers, especially for the key area and industry.

<p><b>OBJECTIVE</b>To explore the occupational stress factors associated with the prevalence of metabolic syndrome (MS) among male policemen.</p><p><b>METHODS</b>Using cluster sampling method, we selected four Public Security Bureau within the jurisdiction of the station now in some city. All the male police were included as research objects, and finally 1490 persons were selected, health and occupational stress inventory-revised (OSI-R) questionnaire were used for epidemiological surveys, and anthropometric examination and chemical indicators were also measured at the same time. The analysis methods were chi-square test and unconditional logistical regression.</p><p><b>RESULTS</b>Among the 1490 of research objects, 1483 completed the questionnaire, and 1480 of the eligible questionnaires were available.237 cases were MS, and the prevalence rate was 16.0%(237/1480). The number of cases who were high, moderate and lack of occupational stress in MS group were 8, 39 and 23, that in non-MS were 14, 114 and 131, respectively. The odds of occupational stress with the highest and medium among policemen than who were lack were 4.82 (95%CI: 1.50 - 15.41) and 3.33 (95%CI: 1.62 - 6.79); the average score of role ambiguity, role insufficiency and responsibility in the group of MS were (38.76 ± 6.83), (25.74 ± 7.22), (25.76 ± 6.27); and that in non-MS were (37.55 ± 6.85), (24.50 ± 6.58), (25.05 ± 5.95). The logistical regression analysis showed that: the likely three occupational risk stress factors which influencing the prevalence of MS were role ambiguity, role insufficiency and responsibility, and the OR (95%CI) were 1.06 (1.02 - 1.10), 1.04 (1.02 - 1.07) and 1.03 (1.01 - 1.06), respectively.</p><p><b>CONCLUSION</b>Role ambiguity, role insufficiency and responsibility were the occupational risk stress factors associated with the prevalence of MS among male policemen.</p>

<p><b>OBJECTIVE</b>To investigate the life style, genetic and occupational risk factors of metabolic syndrome (MS) among policemen.</p><p><b>METHODS</b>1:4 matched case-control study was used, based on physical examination data of Tianjin Policemen in 2010, 708 patients with MS were randomly selected as cases, which were matched with 2832 healthy controls on the basis of sex and age (+/- 1 year). An epidemiological investigations on the past exposure status of several possible risk factors was conducted, and the data were analyzed with conditional logistic regression.</p><p><b>RESULTS</b>Fifteen factors related to exposure were identified for MS through univariate conditional logistic regression analysis. Multivariate conditional logistic regression analysis suggested that, seven factors, such as family history of hypertension (OR = 2.406, 95% CI: 1.946-2.975), family history of diabetes (OR = 1.301, 95% CI: 1.043-1.623), smoking (OR = 1.357, 95%CI: 1.010-1.823), snoring (OR = 1.268, 95% CI: 1.043-1.543), work intensity (OR = 4.603, 95% CI: 3.767-5.623), occupational stressful events (OR = 1.524, 95% CI: 1.209-1.922), security policemen (OR = 1.453, 95% CI: 1.127-1.872) and criminal investigation policemen (OR = 2.792, 95% CI: 2.168-3.596), could significantly increase the risk of disease development, but dairy products (OR = 0.782, 95% CI: 0.619-0.989) was a protect factor for MS. The results from population attributable risk factors analysis showed that the control of smoking, snoring, work intensity, occupational stressful events can decreased the risk of MS to 16.26%, 11.71%, 56.87% and 8.97%, respectively.</p><p><b>CONCLUSION</b>Metabolic syndrome has became a significant public health problem among policemen, it's necessary to take measures on life style, occupational risk factors for reducing the incidence of MS, and improving the health level among policemen.</p>

Objective To explore the feasibility of imaging and treatment of cervical cancer xenograft model using 131I mediated by hNIS gene transfection. Methods The cervical cancer xenograft models were established with Hela-NIS( +) cells and Hela cells, respectively. Five Hela-NIS( +) xenograft models and five Hela xenograft models were dynamically imaged at 0.5, 1, 2, 4, 8, 16 and 20 h postinjection of 131I(7.4 MBq). Five Hela-NIS( +) xenograft models were imaged at 0. 5,1,2,4,8,16, 20 and 25 h postinjection of 99TcmO4-(11.1 MBq). Twenty Hela-NIS( +) cervical cancer xenograft models were randomly divided into four groups: Three 131I treating groups and one control group. The therapeutic effects of 131I at threelevels (74,111,148 MBq) were investigated following intraperitoneal injection. Results Hela-NIS( +)human cervical cancer xenografts were established successfully in nude mice. The Hela-NIS( +) xenografts significantly accumulated radioactivity after intraperitoneal injection of 131I, and the radioactivity was persistently present until 20 h postinjection, but Hela xenografts had no radioactive accumulation. The T/B value of the Hela-NIS( +) xenografts reached 17.34 at 8 h postinjection. The imaging with 99TcmO4- showed that the radioactivity was persistently present in Hela-NIS( +) xenografts for almost 25 h. The Hela-NIS( +)xenografts shrinked after 131I treatment. The inhibition ratios of tumor growth in 111 MBq and 148 MBq groups were both significantly higher than that of 74 MBq group (t: 2.74-5.75, P <0.05). Conclusions Hela-NIS( +) cervical cancer xenografts in nude mice could persistently accumulate 131I and 99TcmO4- and could be treated successfully with 131 I. 131 I treatment mediated by hNIS gene transfection could be a promising cancer treatment method.
摘要
<p><b>BACKGROUND</b>Choledochal cyst is rare in western countries. The relatively high incidence of coexistent hepatobiliary disease increases the difficulty of the surgical management of choledochal cyst. Here we analyze the diagnosis and treatment of congenital bile duct cyst in 122 Chinese adults.</p><p><b>METHODS</b>The clinical data of 122 patients with congenital choledochal cysts admitted from 1981 to 2006 were analyzed.</p><p><b>RESULTS</b>Clinical symptoms in most cases were nonspecific, resulting in delayed diagnosis. Sixty-one patients (50%) had coexistent pancreatobiliary disease. Among the 122 patients, 119 patients underwent ultrasonic examination; ERCP/MRCP was performed in 63 cases and CT in 102 cases. Abnormal pancreatobiliary duct junction was found in 48 patients. Sixteen patients had malignant lesions in the bile duct, arising in 11 of them from incomplete choledochal cyst that underwent various operations including cystenterostomy or cystojejunostomy. There was significant difference between the patients who underwent incomplete cyst resection and complete cyst resection in malignancy rate of bile duct (Chi square test, P = 0.000; odds ratio, 7.800; 95% confidence interval, 2.450 to 24.836).</p><p><b>CONCLUSIONS</b>ERCP, CT and MRCP had proved their great values in the classification of the disease. Cyst excision with Roux-en-Y hepaticojejunostomy is recommended as the treatment of choice for patients with type I or type IV cysts. For type V cyst (Caroli's disease) with recurrent cholangitis, liver transplantation should be considered.</p>
