Objective To observe the serum levels of calcium, phosphorus, alkaline phosphatase (ALP), parathy-roid hormone (PTH) and 25-hydroxyvitamin D, and the influence of biochemical markers of bone turnover in Graves’dis-ease. Methods Sixty-two patients with Graves’disease were enrolled into the Graves’disease group and 91 healthy indi-viduals as a control group. Electrochemical luminescence was used to evaluate the plasma levels of PTH and 25-hydroxyvita-min D in two groups. The serum levels of calcium, phosphorus and ALP were measured with biochemistry methods in two groups. Results The serum levels of calcium, phosphorus, ALP and 25-hydroxyvitamin D were significantly higher in the Graves’disease group compared with those in control group (P<0.01). The serum levels of calcium, phosphorus, ALP and 25-hydroxyvitamin D were significantly higher in female patients than those of control group, and the level of PTH was lower than that of control group. For male patients, the levels of ALP and 25-hydroxyvitamin D were higher than those of control group, and the level of PTH was lower than that of control group. In Graves’disease group, patients with vitamin D deficien-cy were 17 cases (27.4%), insufficiency 20 cases (32.3%) and sufficiency 25 cases (40.3%), respectively. In control group, there were 54 cases with vitamin D deficiency (59.3%), 31 cases with insufficiency vitamin D (34.1%) and 6 cases with suffi-ciency vitamin D (6.6%), respectively. There was no correlation in plasma levels of PTH, 25-hydroxyvitamin D, serum calci-um and serum phosphorus in Graves’disease group. Conclusion The bone turnover is accelerated in Graves’disease. The increased plasma level of 25-hydroxyvitamin D is related with increased calcium level and decreased PTH level in Graves’ disease. The increased serum phosphorus reduces 1-α-hydroxylase activity. Vitamin D deficiency plays a minor role in bone metabolism of Graves’disease.

OBJECTIVETo establish a simple and rapid HPLC-MS method for determining the contents of olmesartan in human plasma.
METHODSPlasma were precipitated with trifluoroacetic acid, then analyzed on an HyPurity C(18) column (150 mm 2.1 mm, 5 microm). Samples at 40 degrees celsius;. The mobile phase consisted of water-methanol- acetonitrile(14:60:26) with a flow rate of 0.22 ml/min.
RESULTSThe lower limit of qualification was 25 microg/L. The calibration curve was linear over the range of 25-3200 microg/L (r=0.9998), with the intra-day and inter-day RSD less than 15%.
CONCLUSIONThe method is sensitive, rapid and suitable for the study of pharmacokinetics and bioavailability of olmesartan.

Objective To compare the clinical effect of ifosfamide in combination with liposomal doxorubicin and dexamethasone (CDD) in the treatment of relapsed/refractory multiple myeloma (MM) with or without extramedullary plasmacytoma (EMP). Methods The clinical data of 71 relapsed/refractory MM patients treated with CDD regimen from January 2011 to December 2016 were retrospectively analyzed, including 48 patients with EMP(group A)and 23 patients without EMP (group B).One cycle of the CDD treatment was 21 d or 28 d and efficacy analysis was performed after every two cycles.Results The overall response rate in group A was 43.8%(21/48)and the complete remission and near complete remission rate was 8.3%(4/48);the overall response rate in group B was 65.2%(15/23)and the complete remission and near complete remission rate was 13.0% (3/23). There were no statistically significant differences between the two groups(χ2=1.203,0.659,P>0.05).The progression-free survival (PFS)time in group A was(8.6 ± 3.3)months, while the PFS time in group B was(7.9 ± 2.5)months and there was no significant difference between the two groups(t=1.009,P>0.05).There was no significant difference about incidence rate of adverse effects between the two groups(P>0.05).Conclusions CDD regimen can be used for the treatment of relapsed/refractory MM with or without EMP, the PFS and drug related adverse effects are similar, especially in patients with EMP.

Objective To investigate the clinical effect of 125I seeds implantation on bone metastasis from radioactive iodine-refractory differentiated thyroid carcinoma (RAIR-DTC).Methods A total of 9 RAIR-DTC patients with bone metastases (4 males,5 females,age range:42-87 years) between April 2014 and December 2016 were enrolled in this prospective study.Treatment plan was developed through treatment planning system (TPS).125I seeds implantation was performed under CT guidance.After 2 and 4 months,metastasis size,serum thyroglobulin (Tg) and verbal rating scale (VRS) pain score changes were recorded.Paired t test and two-sample t test were used for data analysis.Results VRS pain score decreased 2 months post-treatment comparing with that before treatment (2.56±0.88 vs 5.22±2.44;t =4.28,P<0.01).VRS pain score at 4 months post-treatment was 1.78±0.83,which was lower than that at 2 months post-treatment (t =3.48,P<0.01).The maximum tumor diameters before the implantation and 2 months post-treatment were (6.47± 1.84) cm and (5.08±2.11) cm,respectively (t =9.14,P<0.01).The maximum tumor diameter at 4 months post-treatment showed a decreasing trend but it was not statistically different compared to that at 2 months post-treatment:((4.52±2.16) cm;t =2.19,P>0.05).Serum Tg level reduced 2 months after the implantation (lgTg:2.71±0.85 vs 2.94±0.82;t =4.82,P<0.01).Serum Tg level at 4 months post-treatment (lgTg:2.56±0.81) was lower than that at 2 months post-treatment (t =2.69,P<0.05).Conclusions 125I seeds implantation is an effective method for treating bone metastasis from RAIR-DTC.It can help to shrink bone metastasis,alleviate pain and improve patients' quality of life.

Objective To investigate the distribution of sleep duration,daytime naps habits,and insomnia-related symptoms among participants from the China Kadoorie Biobank (CKB) study,and to examine the associations between the sleep-associated factors.Methods A self-designed computer-based questionnaire was adopted to collect social-demographic information and lifestyle-related factors of the participants.A total of 452 829 Chinese adults aged 30-79 years,without self-reported histories of coronary heart disease,stroke,chronic obstructive pulmonary diseases or cancer,were included in this study.General linear regression and multinomial logistic regression models were used to estimate the distributions on duration of sleep,daytime naps habits,and insomnia-related symptoms in different populations,after adjusted for gender,age,and residential regions.Gender-specific logistic regression model was adopted to examine the associations between the above mentioned sleep-related factors.Results The average sleep duration of the participants was 7.41 hours per day,with 20.3% of them having daytime naps all year round,but 40.1% only had daytime naps in summer,and 39.6% had no habits of daytime naps.11.0%,10.0%,and 2.1% of the participants reported having had symptoms as difficulty in falling asleep,waking up too early or with daytime dysfunction,respectively.There were significant differences on the distributions in sleep-related factors between participants with different gender,age,residential areas,education levels,household income,and marital status (P<0.05).Results from the logistic regression showed that longer sleep duration was associated with lower risks of insomnia-related symptoms trend (P<0.001).Factor as without habits of daytime naps seemed to be associated with higher risks of insomnia-related symptoms (P<0.05).Participants with longer sleep duration were more likely to have the habit of taking daytime naps (P<0.05).Conclusions The distributions of sleep duration,habits on daytime naps and insomnia-related symptoms varied according to the differences on social-demographic factors.There were associations existed between the sleeping-related factors,which would influence the promotion on optimal sleep duration and better quality of sleep.
