Objective To establish a REDE-DHPLC method for detecting the EGFR and KRAS mutations in plasma DNA from tumor patients, and investigate its clinical significance. Methods Restriction endonucleases Mse Ⅰ , Msc Ⅰ , BstN Ⅰ and Bgl Ⅰ were used to digest the wild type fragments of exon 19,exon 21 of EGFR gene and coden 12, 13 of KRAS gene for enriching the mutation fragments, and REDE-DHPLC method was established to detect EGFR and KRAS mutations. The sensitivities of REDE-DHPLC and conventional DHPLC were analyzed by using a series of plasmids containing 50%, 10%, 5%, 1% and 0. 1% mutation genes. Then, Plasma samples and paraffin-embedded tissue samples of 120 NSCLC patients and 120 colorectal cancer patients were detected by REDE-DHPLC. Compared with conventional DHPLC and sequencing, the diagnostic efficiency of REDE-DHPLC method was evaluated by detecting the mutation status of 2 genes in plasma of NSCLC and colorectal cancer patients. Results The sensitivity values of REDE-DHPLC and conventional DHPLC for detecting mutations in 4 loci were 0. 1% and 1%respectively. Plasmid DNA containing 0.1% mutation gene was detected to be positive continually for 2 to 3 times by REDE-DHPLC. EGFR mutation rates of 120 plasma from NSCLC patients detected by REDE-DHPLC, conventional DHPLC and sequencing methods were 27. 5%, 16. 7% and 12.5% respectively, and KRAS mutation rates of 120 plasma from colorectal cancer patients were 38. 3%, 25. 8% and 16. 7%,respectively. The positive rates of EGFR and KRAS mutation detected by REDE-DHPLC were significantly higher than conventional DHPLC(x2 = 4. 092, 4. 301, all P < 0. 05 ) and sequencing method (x2= 8. 438,14. 127,all P < 0. 05 ). In comparison with conventional DHPLC, the sensitivities of REDE-DHPLC for detecting EGFR and KRAS mutation were 100% (20/20,31/31), the specificities were 87. 0% (87/100)and 83. 2% (74/89). In comparison with sequencing method, the sensitivities of REDE-DHPLC were 100%( 15/15,20/20), the specificities were 82.9% (87/105)and 74. 0% (74/100). The coincidence rate of the two methods for detecting EGFR and KRAS mutation were 89. 2% ( 107/120, Kappa = 0. 690, P < 0. 05 ) and 87.5% ( 105/120, Kappa= 0. 718, P < 0. 05 ). The Consistency of EGFR and KRAS mutation status in plasma and tissues detected by REDE-DHPLC were 91.7% (33/36, Kappa =0. 939,P <0. 05)and 90. 2 %(46/51, Kappa = 0. 914, P < 0. 05 ), respectively. Conclusions The REDE-DHPLC method is highly sensitive and specific for detecting EGFR and KRAS mutations in plasma DNA from tumor patients. The results are easy to be interpreted without missing homozygous point mutation, which indicate that the detection of EGFR and KRAS mutations in plasma DNA by REDE-DHPLC could therefore extend to be usedin clinical laboratory.

Objective:To study the iodine nutritional status and thyroid function of adult males in iodine nutrition appropriate rural areas of Gansu Province.Methods:In 2017, Liangzhou District and Linze County of Gansu Province with suitable children iodine nutrition were selected as the study areas and 52 males aged 20 - 49 years old were investigated in each study area. One random urine sample was collected to determine urinary iodine. Fasting blood samples were collected to determine serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxin (FT 4), thyroglobulin antibody (TgAb) and thyroid microsomal antibody (TMAb). At the same time, thyroid examination was performed by B-ultrasound. Results:The median urinary iodine of adult males in Liangzhou District and Linze County was 180.2 and 161.0 μg/L, respectively, and the difference was statistically significant ( P < 0.05). There was no goiter in adult males in Liangzhou District and Linze County. The serum TSH (median), FT 3 and FT 4 (mean value) of adult males in Liangzhou District and Linze County were 1.85, 1.61 mU/L, 5.19, 5.16 pmol/L and 16.58, 16.30 pmol/L, respectively. There were no significant differences between the two areas ( P > 0.05). The overall abnormal rate of thyroid function in the two areas was 6.7% (7/104), mainly subclinical hypothyroidism (6/7). The incidences of thyroid dysfunction in Liangzhou District and Linze County were 5.8% (3/52) and 7.7% (4/52), respectively, with no statistical difference between the two areas ( P > 0.05). The total positive rate of antibody was 12.5% (13/104). The positive rates of antibody in Liangzhou District and Linze County were 13.5% (7/52) and 11.5% (6/52), respectively, with no statistical difference between the two areas ( P > 0.05). Both TgAb and TMAb were positive in 9/13 of antibody positive persons, of which the proportion of antibody positive persons in Liangzhou District and Linze County were 7/7 and 2/6, respectively. The 11/13 of the total antibody positive persons were simple antibody positive without thyroid hormone and TSH abnormalities. Conclusion:The iodine nutrition of adult males in iodine nutrition appropriate rural areas of Gansu Province is suitable, but there is a potential risk of thyroid disease in this population, which should be paid attention to and checked regularly.

Objective:To investigate the epidemiological situation of drinking water-type endemic fluorosis in Gansu Province, and scientifically evaluate the effectiveness of water improvement and fluoride reduction projects in preventing and controlling the disease.Methods:The drinking water-type endemic fluorosis areas in Gansu Province were divided into five regions according to different ecological types: the Longzhong Loess Plateau Hilly Area in central Gansu, the Longdong Loess Plateau Gully Area in eastern Gansu, the Longnan Qinling Zhongshan Canyon Area in southern Gansu, the Gobi area of the Hexi Desert, and the Alpine Grassland Meadow Area in southern Gansu. In 2021, a survey was conducted on the basic situation, running situation of the water improvement and fluoride reduction projects, fluoride content in drinking water(fluorine ion-selective electrode), and the prevalence of dental fluorosis (Dean) among children aged 8 to 12 in all drinking water-type endemic fluorosis villages in the five regions. The pertinent assessments were executed in accordance with national guidelines such as the "Standards for Drinking Water Quality" (GB 5749-2006) and "Diagnosis of Dental Fluorosis" (WS/T 208-2011).Results:A total of 2 000 villages in drinking water-type endemic fluorosis areas were monitored, among which 1 999 villages had implemented water improvement and fluoride reduction projects, with a coverage rate of 99.95% (1 999/2 000). All water improvement and fluoride reduction projects were operating normally, with no intermittent operation or scrapping. A total of 34 616 children aged 8 to 12 were investigated for dental fluorosis. The detection rate of dental fluorosis was 4.18% (1 448/34 616), and the dental fluorosis index was 0.09. There was a statistically significant difference in the detection rate of dental fluorosis among children of different ages (χ 2 = 69.77, P < 0.001). The difference in the detection rate of dental fluorosis among children of different ecological types of areas was statistically significant (χ 2 = 775.11, P < 0.001). The dental fluorosis index of children aged 8 - 12 was significantly correlated with the historical water fluoride level ( r = 0.29, P = 0.042). The water improvement time in the Gobi area of the Hexi Desert was significantly correlated with the detection rate of dental fluorosis in local children ( r = - 0.48, P = 0.023). Conclusions:In 2021, the prevention and control of drinking water-type endemic fluorosis in all villages in Gansu Province has reached the national control standards. However, due to the different ecological characteristics and changes in water source distribution in different ecological types of areas, it is still necessary to further strengthen the monitoring of the condition of drinking water-type endemic fluorosis in all the affected villages and consolidate the existing prevention and control achievements.
