Objective To investigate the sleep quality state of people who did physical examination,and its correlation with brachial-ankle Pulse Wave Velocity (baPWV).Methods The indexes of Pittsburgh sleep quality index (PSQI) and baPWV were used.The people who did physical examination were divided into sleep disorders group (284 cases) and normal sleep group (608 cases) according to the results of PSQI survey.Results (1) There were 31.84% of the people who had sleep quality problems.(2) The PSQI total score and the score of subjective sleep quality (SSQ),sleep duration (Sdu),daytime dysfunction (DD) of females were higher than males (t =6.71,3.46,2.45,3.96,P <0.05).The PSQI total score and the score of sleep latency (SL),habitual sleep efficiency (HSE),use of sleeping medication (USM) among different age groups were statistically analyzed (F =12.23,8.31,7.50,7.11,P < 0.05).(3) The score of baPWV of sleep disorders group was higher than normal sleep group (t =5.14,P < 0.05).There were significantly positive correlation between baPWV and total PSQI score,subjective sleep quality,sleep time,daytime dysfunction (r =0.28,0.45,0.30,0.36,0.35,P < 0.05).Conclusions 1/3 of the physical examination people have sleep quality problems.Sleep quality of females is worse than males.There are different styles among different age groups.There is significantly positive correlation between sleep quality and baPWV.

Objective During pregnancy , exosomes can be released from the placenta into maternal circulation and play im-portant roles in normal pregnancy or placenta-related diseases .We aimed to establish a simple and efficient method for isolating and i-dentifying placental exosomes from maternal serum and lay a foundation for the studies of pregnancy -related diseases . Methods Using sucrose gradient centrifugation with 8% PEG6000 precipitation twice , we isolated and purified placenta-derived exosomes from normal maternal serum and detected their molecular markers CD 63 , CD81 and PLAP by Western blot , followed by silver staining anal-ysis of the protein profile of the exosome pellet .We identified the morphology of the placenta-derived exosomes by transmission electron microscopy ( TEM) and measured the size and distribution of the particles by dynamic light scattering ( DLS) . Results Silver stai-ning of the protein profiles of the exosomes after sucrose gradient centrifugation clearly revealed the bands of the protein molecules . Western blot showed the expressions of CD 63, CD81, and PLAP in the 21-34%density layer, which demonstrated the presence of serum placental exosomes mainly in the 1.09-1.16 g/mL density layer.TEM exhibited that the placenta-derived exosomes were round or oval cup-shaped, specifically expressing PLAP, and the particles were uniform in size, with a mean diameter of (41.79 ±11.94) nm. Conclusion A simple, fast, and efficient method was successfully established for isolating placenta-derived exosomes from ma-ternal serum, which provides a basis for studying the roles of placental exosomes in normal pregnancy and placenta -related diseases.

Objective To analyze the correlation between miR-31 and ESCC in expression of miR-31 in the plasma of ESCC in Xinjiang Kazak and Han nationality patients. Methods The plasma samples were collected respectively from patients with ESCC in 20 cases and healthy subjects in 20 cases. The relatively expression of miR-31 was detected by real-time Q-PCR. Results The expression of miR-31 with ESCC were higher than those of the normal control group, which related to the degree of tumor differentiation in Kazak ESCC patients (P < 0.01); the levels of miR-31 relative expression in Kazak were higher than that of Han (P = 0.008, P = 0.027). Conclusion miR-31 may be involved in the occurrence of ESCC in Han and Kazak nationality. miR-31 might be another risk factor in high incidence of ESCC in Kazak than Han nationality.

Objective To analyze the complications of transvaginal natural orifice transluminal endoscopic surgery( TV-NOTES) nephrectomy, and to explore effective measures to prevent and manage those complication.Methods From May 2010 to January 2015, a total of 178 females who had been married and given birth underwent TV-NOTES nephrectomy in our center.The average age was 47 ( ranging 23 to 71 ) years and the average BMI was 23.6 ( ranging 14.7 to 31.9 ) kg/m2.Pathological diagnosis included 142 cases of non-functional kidneys, 29 cases of renal tumors ( T1 N0-1 M0 25 cases, T2 N0-1 M0 4 cases) , and 7 cases of renal tuberculosis.One hundred and sixty hybrid TV-NOTES nephrectomy procedures (simple in 132, radical in 28) and 18 pure TV-NOTES nephrectomy procedures (simple in 17, radical in 1) were performed.Intraoperative and postoperative complications were graded according to Satava and Clavien-Dindo grade classifications.The major complications and relative treatments were analyzed.Results Among the 178 TV-NOTES nephrectomy procedures, there were 40 ( 22.5%) complications occurred, including 13 (7.3%) major complications, in which there were 11 cases of intraoperative complications (6.2%),2 cases of postoperative complications (1.1%).All the complications were successfully managed using organ repair or resection, embolectomy, hemostasis, and so on.No intraoperative and postoperative deaths occurred.There was no significant difference in major complications between hybrid TV-NOTES and pure TV-NOTES nephrectomy (6.9%vs.11.1%, P=0.620).The intraoperative major complications in the early developmental stage of TV-NOTES nephrectomy were more than that of the late stage (20.0%vs.3.4%, P=0.004).There was no significant difference in postoperative complications between the early and late developmental stage of TV-NOTES nephrectomy (13.3%vs.10.8%, P=0.751).Conclusions TV-NOTES nephrectomy is safe and feasible, but there are some major complications worthy of attention.Personal prevent and treatment strategy should be considered.

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.
