Objective To evaluate the short-term efficacy and safety of combination therapy with amlodipine and terazosin in middle aged and old male patients with essential hypertension.Methods Randomized,prospective,parallel study was carried out in middle aged and old male patients with essential hypertension in Anqing community between August 2005 and February 2006.Antihypertensive efficacy and safety of the combination therapy were evaluated in 508 patient who completed the study.Results After 4 weeks treatment,the average reduction of SBP were 4.0?15.0,17.5?15.8 and 20.0?15.9 mm Hg in Terazosin group,amlodipine group and combination group,respectively(P

Objective: To investigate the epidemilogical characteristics of pulmonary tuberculosis in Huzhou City, Zhejiang Province from 2014 to 2023, so as to provide the basis for formulating prevention and control measures for the construction of "TB-free city". Methods: The data of pulmonary tuberculosis cases in Huzhou City from 2014 to 2023 was collected through the Infectious Disease Reporting Management System of Chinese Disease Prevention and Control Information System. The onset time, region, and population distribution characteristics of the cases were described. Results: A total of 11 598 cases of pulmonary tuberculosis were reported in Huzhou City from 2014 to 2023, with an average annual incidence of 37.42/105. The reported incidence decreased from 47.50/105 in 2014 to 28.36/105 in 2023 (P<0.05), with an annual decline rate of 5.57%. There were 6 304 etiological positive cases, accounting for 54.35%. The peak season for pulmonary tuberculosis cases was from March to September, with the highest seasonal ratio of 112.48% in May. The average annual reported incidence rates in Anji County and Changxing County were relatively high (46.14/105 and 41.15/105). The reported incidence rate of pulmonary tuberculosis in Huzhou City increased with age (P<0.05), peaking at 97.36/105 in the group aged 75 to <80 years. There were 7 991 male pulmonary tuberculosis cases and 3 607 female cases, with a male-to-female ratio of 2.22∶1. The average annual incidence rates of pulmonary tuberculosis was higher in males than in females (50.39/105 vs. 23.87/105). Farmers were the primary occupation affected, with 6 350 cases accounting for 54.75%. Conclusions The reported incidence rate of pulmonary tuberculosis in Huzhou City decreased from 2014 to 2023, with a high incidence in spring and summer. The incidence rates in Anji County and Changxing County were higher than Huzhou City's average. Male, elderly residents and farmers were the key populations for pulmonary tuberculosis prevention and control.

Objective To explore the association between dyslipidemia and the level of 8-OHdG/Cr in urine among a population exposed to chronic arsenic.Methods Four hundred and seven subjects were randomly selected in an arsenic-affected area in Inner Mongolia.After blood biochemical examination,all the subjects were divided into 4 groups based on the results of total cholesterol (TC),triglycerides (TG),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C).The groups consisted of hypercholesterolemia,HDL-C ratio anomaly,combined hypercholesterolemia and HDL-C ratio anomaly,as well as a normal lipid group.Urine samples were collected and 8-OHdG/Cr was measured using the ELISA method.A generalized linear mixed model was used to analyze the association between dyslipidemia and 8-OHdG/Cr.Results The levels of 8-OHdG/Cr as 55.73 (39.90-79.94) ng/mg,58.08 (44.94-69.91) ng/mg,65.28 (49.29-92.95) ng/mg and 51.43 (36.86-68.57)ng/mgin the HDL-C ratio anomaly,hypercholesterolemia,combined hypercholesterolemia and HDL-C ratio anomaly groups and the control group,respectively,which showed significant differences on the levels of 8-OHdG/Cr in the four groups (P=0.006).From the linear regression analysis results showed that the 8-OHdG/Cr level incombined hypercholesterolemia and HDL-C ratio anomaly group was higher (4.25 ± 0.55 ng/mg) than in the control group (3.96 ± 0.55 ng/mg) (P=0.018).After adjusting for important covariates,there was a linear trend between the levels of 8-OHdG/Cr and dyslipidemia (P=0.016).Conclusion Data from our study showed a linear relation between hypercholesterolemia,HDL-C ratio anomaly and the 8-OHdG/Cr level,suggesting that dyslipidemia was associated with oxidative DNA damage among those arsenic-affected people.
