ABSTRACT
The incidence rate of thyroid cancer and thyroid nodule in China are rising and surgical operation is the main treatment for thyroid nodule and thyroid carcinoma.It has been controversial whether thyroid surgery is suitable for day surgery.Perfect preoperative examination and anesthesia assessment,selection of an appropriate of patients and minimally invasive surgery,good postoperative analgesia and the prevention and treatment of postoperative nausea and vomiting,recognition and treatment of postoperative complications timely,postoperative follow-up,can ensure safety of patient with thyroid ambulatory surgery,and made the same medical quality as the surgery in hospital.Under certain criteria,thyroid ambulatory surgery is safety,high efficient,economy and time-efficient.It is a reasonable surgical management mode which can reduce days of hospitalization and hospitalization cost.But it still need further study on the inclusion and exclusion criteria of patients,anesthesia techniques and perioperative management.
ABSTRACT
Objective To understand the association between peripheral leukocytes telomere length (TL) and sleep in middle-aged and old adults.Methods A total of 176 middle-aged and old adults were investigated by using the Pittsburgh Sleep Quality Index and questionnaire.TL was measured by fluorescence quantitative PCR.The correlation and regression analysis between sleep and telomere length was performed.Results TL had a mean T/S ratio of 0.995 ± 0.23.There was a negative correlation between TL and age (r=-0.241,P=0.003).With increasing age,sleep quality became worse (r=-0.230,P＜0.01),the time to fall asleep became longer (r=0.227,P＜0.01),sleep duration was shorter (r=-0.486,P＜0.01),sleep efficiency became worse (r=-0.226,P＜0.01).After controlling for the effects of gender,age,marital status,income level,residence,smoking,drinking,physical exercise and disease status,multiple linear regression analysis indicated that sleep quality (β3=0.057,P＜0.01),time to fall asleep (β =-0.046,P＜0.01),sleep duration (β3=0.086,P＜0.01) were independent influencing factors of telomere length,suggesting that the people who had better sleep quality,the shorter time to fall asleep,the longer sleep time would have longer telomere length.Conclusions Sleep is a relevant factor affecting TL in middle-aged and elderly population.Good sleep may delay aging by slowing TL.We encourage to conduct health education about the importance of sleep quality in community.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the levels and influencing factors of phthalate internal exposure in pregnant women (gestation age ≤ 16 weeks).</p><p><b>METHODS</b>During April to June in 2013, 1 020 pregnant women (gestation age ≤ 16 weeks) who had established the maternal care manual were recruited in maternal and child health hospital of Siming District, Xiamen city. Participators were asked to complete a questionnaire to obtain information on socio-demographic characteristics, lifestyle behaviors, and antenatal examination and to provide a urine sample. Finally, 998 pregnant women who provided a urine sample and completed the questionnaire were enrolled. Adopting systematic sampling method, 100 ones were selected randomly among 998 pregnant women. High performance liquid chromatography-electrospray ionization-tandern mass was used to determine the concentration of five phthalate monoesters in each urine, including mono-n-methyl phthalate (MMP), mono-ethyl phthalate (MEP), mono-butyl phthalate (MBP), mono-benzyl phthalate (MBzP), mono-ethylhexyl phthalate (MEHP). Based on the measurements and questionnaire data, multivariate logistic regression was used to analyze the association between the phthalate monoester levels and potential influential factors.</p><p><b>RESULTS</b>The detection rates of MMP, MEP, MBP, MBzP and MEHP in 100 pregnant urine samples were 94%, 93%, 87%, 83%, 99%, respectively. And the urinary median uncorrected concentrations of MMP, MEP, MBP, MBzP and MEHP in 100 urine samples were 20.56, 17.62, 10.15, 2.03, and 5.12 ng/ml, respectively. Specific gravity-corrected concentration were 20.81, 20.36, 12.88, 2.58, 5.00 ng/ml, respectively. The results of multivariate logistic regression analysis indicated that: education degree was negatively associated with urinary concentration of MMP, MEP, MBP, MBzP and MEHP, OR (95% CI) were 0.495 (0.253-0.966), 0.380 (0.191-0.755), 0.379 (0.186-0.774), 0.401 (0.196-0.819), 0.373(0.183-0.762), respectively. Participants who had hair permed and dyed during pregnancy had higher urinary level of MBP and MBzP, OR (95% CI) were 12.867 (1.240-133.525), 15.982 (1.367-186.911), respectively; Participants who use cosmetics during pregnancy had higher urinary level of MEP and MBP, OR (95% CI) were 2.977 (1.012-8.757), 4.440 (1.485-13.272), respectively; plastic bottled water consumption was positively associated with urinary concentrations of MEP and MEHP, OR (95% CI) were 3.780 (1.417-10.083), 2.699 (1.039-7.010), respectively; annual household income was negatively associated with urinary concentration of MMP, OR (95% CI) was 0.597 (0.372-0.959); individuals who took medications during pregnancy had higher urinary level of MEHP than non-takers, OR (95% CI) was 4.853 (1.084-21.732).</p><p><b>CONCLUSION</b>Pregnant women whose gestation age was less than 16 weeks are generally exposed to phthalate. Phthalate internal exposure levels are significantly associated with most measured factors and the influencing factors with different phthalates internal exposure levels are different.</p>
