In 2020, 1 677 people were monitored in national brucellosis monitoring sites, 151 were RBPT positive, 80 were SAT positive, 80 were diagnosed, and the prevalence rate was 4.77% (80/1 677). There were significant differences in RBPT positive rate, SAT positive rate and prevalence rate among national monitoring sites between the two years (χ 2 = 12.52, 4.24, 4.24, P < 0.05). In 2019, a total of 6 043 people were monitored in provincial brucellosis monitoring sites, 128 were RBPT positive, 91 were SAT positive, 87 were diagnosed, and the prevalence rate was 1.44% (87/6 043). In 2020, 5 664 people were monitored, 108 were RBPT positive, 59 were SAT positive, 52 were diagnosed, and the prevalence rate was 0.92% (52/5 664). There was no significant difference in RBPT positive rate among provincial monitoring sites between the two years (χ 2 = 0.66, P = 0.416), and the differences in SAT positive rate and prevalence rate were statistically significant among provincial monitoring sites between the two years (χ 2 = 4.98, 14.57, P < 0.05). Conclusion:In 2019 and 2020, there are human brucellosis in national and provincial brucellosis monitoring sites in Qinghai Province.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

OBJECTIVE:To explore the potential correlation between clinical efficacy of pemetrexed in the treatment of ad-vanced breast cancer and TS mRNA expression. METHODS:Patients with advanced breast cancer were recruited in our study. Three cycles of pemetrexed was given to these patients,TS mRNA expression of their tumor tissues were detected. The relationship of ther-apeutic efficacies of different chemotherapy with TS mRNA expression were observed and compared during the study period. RE-SULTS:58 patients received pemetrexed chemotherapy and therapeutic efficacies of them were evaluated. One patient (1.7%) had complete response,19 patients(32.8%)had partial response,31 patients(53.4%)had stable response and 7 patients(12.1%)has progressive disease. Objective response rate was 34.5%,and disease control rate was 87.9%. TS mRNA expression level of 55 pa-tients with completed TS mRNA expression analysis varied from 0.04 to 5.11,with a median of 0.62. Mann-Whitney rank test showed that,responders had lower TS mRNA expression than nonsponders at all visits,there was statistical significance (P<0.05). Chi-square test showed that patients with low expression level of baseline(before chemotherapy)TS mRNA had significantly higher objective response rate(63.3%)than those with high expression(36.7%),there was statistical significance(P<0.05). CON-CLUSIONS:TS mRNA expression level is related to therapeutic efficacy of pemetrexed,which may be useful for predicting thera-peutic efficacy of pemetrexed therapy in patients with advanced breast cancer.
