RESUMO

{L-End}Objective To investigate the current status of sleep quality and its influencing factors among coal miners in a company in Shanxi Province. {L-End}Methods A total of 1 047 coal miners from a coal mine company in Shanxi Province were selected as the study subjects by convenient sampling method. The occupational stress, occupational burnout and sleep quality of the study subjects were investigated using Occupational Stress Core Scale, Maslach Burnout Inventory-General Survey and Pittsburg Sleep Quality Index Scale. {L-End}Results The detection rates of occupational stress, occupational burnout, sleep disorder were 58.9%, 59.1% and 57.9%, respectively. The result of multivariate logistic regression analysis showed that education level, alcohol consumption, work shift, duration of dust-exposure, phase of respiratory symptoms, self-assessment of health, occupational stress and occupational burnout were independent influencing factors of sleep disorders in the coal miners (all P<0.05). Among them, the risk of sleep disorders in drinkers was higher than that in non-drinkers (P<0.05); the risk of sleep disorders was higher in miners working in a rotating work shift with two shifts than in those with three shifts (P<0.05); the higher the education level, the longer the duration of dust-exposure, the more serious the phase of respiratory symptoms, the worse the self-assessment of health, the higher the degree of occupational stress and the higher the degree of occupational burnout, the higher the risk of sleep disorders (all P<0.05). {L-End}Conclusion The incidence of sleep disorders in coal miners in this company is relatively high. Occupational stress, occupational burnout, education level, alcohol consumption, work shift, duration of dust-exposure, respiratory symptoms and health status are risk factors for sleep disorders in coal miners.

RESUMO

Objective To compare the efficacy and safety of tenofovir disoproxil fumarate ( TDF) and entecavir(ETV) in the treatment of chronic hepatitis B(CHB) with positive hepatitis B E antigen(HBeAg). Methods A total of 104 cases with newly diagnosed HBeAg positive CHB were selected and randomly divided into TDF group and ETV group,with 52 cases in each group. The TDF group was given 300mg/d TDF,and the ETV group was given 0. 5mg/d ETV. All the patients were continuously treated for 12 months. The serum HBV DNA, HBeAg and ALT levels before and after treatment were compared between the two groups. Results Before treatment,there were no statistically significant differences in serum HBV DNA,HBeAg and ALT levels between the two groups ( t=0. 12, 1. 51,1. 62,all P>0. 05). The serum HBV DNA,HBeAg and ALT levels in the two groups were decreased after treatment,and the decrease of serum HBV DNA level in the TDF group was more significant than that in the ETV group,the difference was statistically significant(t =3. 54,P <0. 05),but there were no statistically significant differences in serum HBeAg and ALT levels between the two groups(t=0. 04,0. 79,all P>0. 05). The total effective rate of the TDF group was 92. 31% (48/52),which was significantly higher than 76. 92% (40/52) in the ETV group (χ2=4. 73,P<0. 05). During treatment,the incidence rate of adverse reaction of the TDF group was 7. 69% (4/52),which was lower than 11. 54% (6/52) of the ETV group,but the difference was not statistically significant (χ2=0. 44,P>0. 05). Conclusion TDF has better clinical effect in treating newly diagnosed HBeAg positive CHB than ETV due to TDF can inhibit HBV DNA replication significantly,but the safety of TDF and ETV is similar.

RESUMO

Objective@#To explore the associations between exposure to chlorination disinfection by-products (CDBPs) during gestation and newborns' small for gestational age (SGA).@*Methods@#During April 2010 to July 2012, a total of 3 903 pregnant women who lived in a district with the same water treatment plant in Wuhan, China were recruited to this perspective study. Information about demographic characteristics of pregnant women and their newborns was collected. The tap water samples were monthly collected for 28 months in 3 different sites, with 84 samples, and 4 kinds of trihalomethanes (THMs)(chloroform (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform (TBM)) and 2 kinds of chlorohaloacetic acids (HAAs) (trichloroacetic acid (TCAA), dichloroacetic acid (DCAA)) were determined. The pregnant women were divided into 4 groups(Q1 to Q4) by quartile method according to their exposure level of CDBPs. Binary Logistic regression models were used to assess the associations between exposure to CDBPs during gestation and newborns' small for gestational age.@*Results@#The average weight of all the newborns was (3 310.19±389.91) g, of which 169 (4.33%) were SGA. The median concentrations of TCM, BDCM, bromo-THMs, total THMs, TCAA, and DCAA during the whole pregnancy were 18.07, 4.93, 8.51, 26.74, 10.65, and 13.77 μg/L, respectively. Binary Logistic regression analysis showed dose-response relationships between elevated TCM and total THMs during the whole gestation and compared with Q1 group, while there was a increased risk of SGA in Q4 group, and OR(95%CI) was 1.87 (1.01-3.49) , 2.30 (1.22-4.35) , respectively (P for trend equaled to 0.044, 0.015). Compare with Q1 group, there also be positive associations between exposure to TCAA (Q4 group) during first-trimester and the whole gestation and SGA, while OR(95%CI) was 2.16 (1.19-3.91) (P for trend equaled to 0.015).@*Conclusion@#Exposure to CDBPs during gestation might increase the risk of newborns' SGA.

RESUMO

Objective To evaluate the therapeutic effect of modifiedHuanglian-Jiedudecoction for resistant hypertension and explore its possible mechanism.Methods A total of 90 patients with resistant hypertension were recruited and randomly divided into a treatment group and a control group, 45 patients in each group. The control group was treated with oral administration of irbesartan and hydrochlorothiazide tablets and controlled-release nifedipine tablets, while the treatment group was further added modifiedHuanglian-Jiedu decoction for 4 weeks. Plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) were measured by radioimmunoassay.Rusults The total efficiency according to the TCM syndrome in the treatment group was 86.7%(39/45) which was higher than 64.4%(29/45) in the control group(χ2=4.873,P=0.027). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after the treatment in both groups ( SBP in the treatment group: 119.26 ± 9.34 mmHgvs.172.11 ± 10.52 mmHg,t=25.201,P<0.01; DBP in the treatment group: 78.18 ± 7.21 mmHgvs.111.12 ± 11.16 mmHg,t=16.631, P<0.01; SBP in the control group: 145.21 ± 7.56 mmHgvs.171.32 ± 11.15 mmHg,t=13.002,P<0.01; DBP in the control group: 93.57±8.13 mmHgvs. 109.89 ± 12.21 mmHg,t=7.463,P<0.01), while the decrease of SBP (t=14.487,P<0.01) and DBP (t=9.501, P<0.01) in the treatment group was more greater than those in the control group. The control rate of blood pressure in the treatment and control groups were 73.3% (33/45) and 55.6% (25/45), respectively, there had no significant difference (χ2=2.376,P=0.123). The plasma ET in the treatment group was significantly decreased than that in the control group (75.68 ± 10.67 ng/Lvs.112.79 ± 12.26ng/L;t=15.317,P<0.05), and CGRP significantly increased (49.87 ± 4.75 ng/Lvs.33.87 ± 7.89 ng/L;t=11.654,P<0.05).Conclusion Modified Huanglian-Jiedudecoction may have some therapeutic effect for resistant hypertension, its mechanism may be involved in ET decreasing and CGRP increasing.
