Objective:To investigate different sleep duration and glucose and lipid metabolism levels in residents of a community in Urumqi.Methods:Using the 2 049 residents′ data of chronic metabolic disease in a community of Urumqi collected in May 2017, 1 822 subjects aged between 19-80 years with complete information were enrolled, their blood pressure, waist circumference, height, weight, body mass index were measured and recorded. Using oral glucose tolerance test to measure fasting and 2 h after meal plasma glucose, uric acid, HbA 1C, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C) levels were all tested. Results:(1)There were 363 (19.9%), 1 349 (74.0%), and 110 (6.1%) respondents with sleep time≤6.0, 6.1 to 8.0, and>8.0 h/d, respectively. There were statistically significant differences in age, education, and family income in groups with different sleep time ( P<0.05), while their gender, smoking status, and exercise status were not statistically significant ( P>0.05). The rates of overweight, obesity, abdominal obesity, high uric acid, and hypertension in people with different sleep durations were statistically different ( P<0.01). The rates of the above indicators were higher in the group of sleep time≤6.0 h/d than the other two groups. (2) Differences in diastolic blood pressure, systolic blood pressure, body mass index, abdominal circumference, total cholesterol, and LDL-C levels were statistically significant among different sleep duration groups ( P<0.05). Further comparisons of the above indicators among three groups with different sleep durations were performed ( P<0.05). The levels of the above indicators in the sleep time≤6.0 h/d group were higher than those in the other two groups. There were no significant differences in fasting blood glucose, glycated hemoglobin, uric acid, triglyceride, and HDL-C among the three groups. (3) Multivariate logistic regression analysis showed that groups whether or not adjusted of age, family income, and education level, sleep time≤6.0 h/d was related to abdominal obesity, and sleep time≤6.0 h/d was be a risk factor for abdominal obesity [Unadjusted: OR=1.48(95% CI1.04-2.08); Adjusted: OR=1.65(95% CI1.18-2.32; P<0.05]. Conclusion:Sleep time ≤6.0 h/d is associated with abdominal obesity, and sleep time≤6.0 h/d may be a risk factor for abdominal obesity.

Objective:To observe the dynamic changes of thyroid hormone levels and thyroid autoimmune antibodies in pregnant women in Xinjiang Uygur Autonomous Region during pregnancy, and to investigate the significance of repeated screening of thyroid function in different gestational ages.Methods:A retrospective study was carried out of pregnant women who completed thyroid function screening in Clinic, People's Hospital of Xinjiang Uygur Autonomous Region from January 2015 to December 2017, and the test results of thyroid stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), thyroid peroxidase antibody (TPOAb), and anti-thyroglobulin antibody (TGAb) were collected and analyzed of their changes during pregnancy. Pregnant women were divided into 2 different gestational age groups by the age limit of 30, the changes of thyroid dysfunction rate with pregnancy were analyzed, and the clinical significance of repeated screening in different pregnancy stages was discussed. Results:Changes of thyroid-related indicators with pregnancy: first, second, and third trimesters were 404,725, and 767 cases, respectively; TSH level in the third trimester (2.76 mU/L) was significantly higher than those in the first and second trimesters (2.55, 2.36 mU/L, P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the FT 4 and FT 3 levels decreased gradually with pregnancy ( P < 0.05); the positive rate of TPOAb was significantly higher in the first and second trimesters than that in the third trimester ( P < 0.05), there was no significant difference between the first trimester and the second trimester ( P > 0.05); the positive rate of TGAb decreased gradually with pregnancy ( P < 0.05). Comparison of abnormal rate of TSH in different gestational ages: the first, second, and third trimesters were 352, 664, 735 cases, respectively; the abnormal rate of TSH in the overall study was statistically significant at different stages of pregnancy (χ 2=31.627, P < 0.05), the first trimester was significantly higher those in the second and third trimesters ( P < 0.05). In pregnant women aged ≥30 years old, the abnormal rate of TSH in the first trimester was significantly higher than those in the second and third trimesters ( P < 0.05); in pregnant women aged < 30 years old, the abnormal rate of TSH in the first trimester was significantly higher than that in the third trimester ( P < 0.05). There were no significant differences in the abnormal rate of TSH in the first, second, and third trimesters between the < 30 years old group and ≥30 years old group ( P > 0.05). Comparison of abnormal rate of FT 4 in different gestational ages: there were no significant differences in the FT 4 abnormal rate among different pregnancy groups in the overall, < 30, ≥30 years old groups (P > 0.05). In early pregnancy, the abnormal rate of FT 4 in the ≥30 years old group was higher than that in the < 30 years old group ( P < 0.05); in second and third trimesters, there were no significant differences between the two age groups ( P > 0.05). Conclusions:Screening for thyroid function in the first trimester of pregnancy is important for women of different ages. Except for women with abnormal thyroid function who have not been treated during the first trimester, the rest may not need to be screened again. Pregnant women aged ≥30 years old may have a higher risk of thyroid dysfunction than those < 30 years old.

BACKGROUND: The most common soft liners currently used in the clinic are silicone rubbers and acrylics, but both of them have deficiencies. Therefore, the development of soft lining materials with stability, excellent performance, and antibacterial properties is of important clinical significance. OBJECTIVE: To prepare a soft lining material with high elasticity on the basis of excellent characteristics of Eucommia ulmoides gum, and to preliminarily explore its water absorption and solubility. METHODS: The basic formula was made based on the existing formula of elastic Eucommia ulmoides gum and medical rubber, in combination with the specific requirements of denture lining materials. The ratio of Eucommia ulmoides to butadiene rubber was set to be 10:90, 30:70, 50:50, 70:30 and 90:10, and the new Eucommia ulmoides gum composite soft denture liners were then prepared. Acrylate self-curing soft lining material and Silagum silicone rubber denture soft lining material served as controls. Afterwards, the samples were put into distilled water or artificial saliva for 7 and 30 days, and the value of water absorption and water solubility were calculated. RESULTS AND CONCLUSION: (1) In the artificial saliva for 7 and 30 days, the water absorption rate and solubility of samples in different ratio groups were close to those in the Silagum group, but extremely lower than those in the acrylate group. (2) In the distilled water for 7 and 30 days, the water absorption rate and solubility of samples in different ratio groups were close to those in the Silagum group, but extremely lower than those in the acrylate group. (3) The water absorption rate and solubility of the acrylate group were significantly higher than those in the other groups at 7 and 30 days of immersion in the artificial saliva or distilled water (P < 0.05). (4) After 7 and 30 days of immersion, the water absorption rate of the same sample in the artificial saliva was significantly lower than that in the distilled water. Wile at 7 days of immersion, the samples in the 30:70 and 50:50 groups showed a lower solubility in the artificial saliva than in the distilled water (P < 0.05), and at 30 days of immersion, the samples in the 30:70, 50:50, 70:30 and 90:10 groups showed a lower solubility in the artificial saliva than in the distilled water (P < 0.05). (5) In the artificial saliva, there was no significant difference in the solubility in the 50:50 and 70:30 groups at 7 and 30 days of immersion (P> 0.05), while the solubility in the other groups exhibited significant differences at different observational times (P < 0.05). In the distilled water, there was no significant difference in the solubility in the 10:90 and 30:70 groups at 7 and 30 days of immersion (P> 0.05), while the solubility in the other groups exhibited significant differences at different observational times (P < 0.05). To conclude, the water absorption of Eucommia ulmoides gum composite soft denture liner is close to Silagum, but significantly less than that of acrylate soft lining materials, and the solubility remains at a very low level.

Objective To establish a reference range for specific thyroid function during pregnancy and to explore the influencing factors of hypothyroxinemia during pregnancy.Methods A retrospective analysis of 2 996 cases of thyroid function in the pregnant women who were with single pregnancy and without thyroid diseases and family history of those diseases.Results (1) Establish a unified reference range for specific thyroid function during pregnancy;the early,middle,and late trimesters thyrotropin (TSH) ranges were 0.02-6.39,0.16-6.23,0.64-6.59 mU/L,respectively,while free thyroxine (FT4) ranges were 11.32-23.00,9.39-18.92,8.54-16.73 pmol/L respectively.The specific reference ranges of Han and Uygur pregnant women were established separately.There was no difference in the detection rates of various thyroid diseases when using their respective reference ranges and the unified reference range of the hospital (P ＞ 0.05).(2) The detection rate of various thyroid diseases (except subclinical hyperthyroidism) of our subjects with China guideline reference range was significantly higher than the reference range with the hospital (P＜0.05).(3) The detection rates of hypothyroxinemia in all pregnant women with FT4 cut points of P2.5 and P5 were 4.3％ and 7.4％,respectively,of which the Han population was 4.3％ and 7.1％,respectively,and the Uygur population was 4.3％ and 7.9％,respectively.(4) Comparing the mean age,gestational age,median urine iodine,and thyroid antibody positive rate between the hypothyroxinemia group and the control group,only the mean age and gestational age were different (P＜0.05);Logistic binary regression analysis showed that age was the risk factor for hypothyroxinemia during pregnancy (OR =1.035,95％ CI 1.006-1.066,P ＜ 0.05).Conclusions The Han and Uygur pregnant women in this area both can use the thyroid reference range of our hospital during pregnancy.The establishment of thyroid reference range may avoid over-diagnosis of thyroid disease during pregnancy.Age is a possible influencing factor of hypothyroxinemia during pregnancy.

Objective To investigate the status of increased blood parathyroid hormone(PTH)level among community residents in Urumqi,and to analyze its correlation with the metabolic parameters including serum Ca and P levels. Methods In May 2013,a cross-sectional survey was conducted,when 1 473 permanent residents in Urumqi, including 844 Han and 629 Uyghurs,were selected by cluster random sampling. PTH and 25-OH vitamin D[25(OH)D] levels were detected by chemiluminescence. Blood Ca, P, Mg, albumin, and creatinine (Cr) were also measured. Based on serum 25(OH)D level,the residents were divided into vitamin D deficiency(<20 ng/ml), vitamin D insufficiency(≥20 and<30 ng/ml),and vitamin D sufficiency(≥30 ng/ml)groups. According to the PTH level,the residents were divided into PTH<65 pg/ml group and PTH≥65 pg/ml group. The metabolic parameters including Ca and P were compared among different ethnic groups. Results In the surveyed population,the rate of increased blood PTH was 12.22%,being higher in females than that in males(13.82% vs 8.45%,P=0.004)and higher in Han Chinese than that in Uyghurs(19.87% vs 6.52%,P<0.01). The proportions of residents with vitamin D sufficiency,insufficiency and deficiency were 3.34%,9.06%,and 87.60% in Uyghurs,and 10.43%,29.98%, and 59.60% in Han,respectively. The rate of 25(OH)D deficiency was significantly higher in Uyghurs than that in Han(P<0.01),especially higher in female Uyghurs(91.43%). In vitamin D deficiency group,the rate of increased serum PTH was significantly increased,higher in Uyghurs than that in Hans(22.14% vs 6.56%,P<0.01),which revealed a negative correlation with 25(OH)D(r=-0.251, P< 0.01). Conclusion 25(OH)D deficiency is prevalent among the community population in Urumqi, with ethnic differences in serum PTH level and the rate of increased blood PTH,which might be associated with vitamin D deficiency.

Objective To investigate the relationship between thyrotropin(TSH)and urine iodine in pregnant women of Han and Uygur ethnic groups in People′s Hospital of Xinjiang Uygur Autonomous Region. Methods A total of 1568 pregnant who completed screening of TSH and urine iodine in People′s Hospital of Xinjiang Uygur Autonomous Region hospital from August 2014 to December 2017 were included in the study, 956 cases were Han and the other 612 were Uygur. Basic clinical data, serum TSH, thyroid peroxidase autoantibody (TPOAb), and urine iodine levels were retrospectively analyzed. Results (1) General results:The median urine iodine level was 162.6μg/L(53.4-539.3μg/L), and the distribution of urine iodine classification was iodine deficiency 42.9％(672/1568), iodine appropriate 36.7％(576/1568), iodine slightly high 17.1％(268/1568)and iodine excess 3.3％(52/1568)respectively.(2)The median urine iodine levels of Han and Uygur pregnant women were 169.1μg/L(54.6-583.4μg/L)and 156.3μg/L (53.1-539.3μg/L)respectively, and the difference was statistically significant(P<0.05).The distribution of urine iodine status in pregnancy between Han and Uygur was significantly different, which were 40.9％(391/956)vs. 45.9％(281/612)in iodine deficiency, 35.4％(338/956)vs. 38.9％(238/612)in iodine appropriate, 20.2％(193/956) vs. 12.3％(75/612) in iodine slightly high and 3.6％(34/956) vs. 2.9％(18/612)in iodine excess.(3)High serum TSH level proportion was significantly higher in Uygur ethnic group, early pregnancy, thyroid peroxidase antibody positive and anti-thyroglobulin antibody positive group when compared with Han, late pregnancy, thyroid peroxidase antibody negative and anti-thyroglobulin antibody negative groups (all P<0.05). There were no significant differences in different age groups and iodine nutrition groups(P>0.05).(4)There was no correlation between urinary iodine and TSH levels in all pregnant women(P>0.05),neither in Han or Uygur group. When further stratified by gestational age, age, and antibody level, there was a positive correlation between urine iodine and serum TSH level in Han pregnant women>30 years old(P<0.05), and there was a negative correlation in the third trimester in Uygur (P<0.05). When serum antibody level, gestational week and age were controlled. There was no correlation between urine iodine and serum TSH level in neither group. Conclusions (1)In Han and Uygur pregnant women, the median urine iodine level and the distribution of urine iodine classification between two ethnic groups are significantly different.(2)The correlation between urine iodine and serum TSH is not identified in Han or Uygur pregnant women.

Objective: To study the effects of a standardized diagnosis and treatment program for type 2 diabetes mellitus patients, in a community in Urumqi. Methods: In March 2016, 1 000 patients with type 2 diabetes at the Urumqi Xinhua Road community health service center and affiliated communities were selected to participate in a questionnaire survey and in a promotion for a 12-month standardized treatment. T-test and χ² test were used to compare the blood sugar, blood pressure, blood lipids, ratio of urine microalbumin and creatinine (urine A/C) and other metabolic indices in patients before and after the promotion. Results: In a total of 112 finalists, after a 4-month follow-up, rates of regular exercise, diet control, taking medication on time and regular blood glucose monitoring all improved significantly from 35.7%, 40.2%, 13.7%, 29.5% to 56.3%, 68.8%, 56.3%, 45.5%, respectively (χ²=9.508, 8.643, 45.319, 6.171; P < 0.05). The rates of smoking and drinking were lower after the promotion (χ²=4.291, 4.56; P < 0.05). Body mass index (BMI), fasting blood glucose (FPG), glycated hemoglobin (HbA1c), systolic blood pressure, total cholesterol (TC), creatinine, and urine A/C decreased significantly, while there was no significant difference in the diastolic blood pressure. The percentage of participants with normal blood sugar, lipids and blood pressure, significantly improved from 38.4%, 37.5%, 23.6%, 8.9% to 63.4%, 66.4%, 43.7%, 23.2%, respectively. The rate of urine A/C positivity decreased from 40.2% to 26.8% (χ²=14.004, 18.309, 10.604, 8.473, 4.510, P < 0.05). Conclusion Standardized type 2 diabetes treatment programs can improve the blood levels of glucose and lipids, as well as lower blood pressure and the positive rate of urine A/C. It can help reduce the multiple risk factors and long-term complications by improving the self-management of diabetes.

Objective·To analyze the clinical characteristics of decompensated cirrhosis patients with intestinal obstruction and related risk factors.Methods·Clinical data of 1 783 decompensated cirrhosis patients treated between March 2010 and March 2016 were collected.Of them,128 (7.18％) patients with intestinal obstruction were screened as the observation group and 128 patients without intestinal obstruction were randomly selected as the control group.Clinical data of two groups were retrospectively investigated,clinical characteristics were compared and analyzed,and related risk factors were analyzed with the Logistic regression analysis.Results·The clinical symptoms of decompensated cirrhosis patients with intestinal obstruction were hidden and misdiagnoses or delayed diagnoses were common.The incidences of abdominal pain,abdominal distension,vomiting,stop exhaust defecate,ascites,electrolyte disorders,fever,and spontaneous peritonitis were significantly higher in the observation group than in the control group (P ＜ 0.05).The results of univariate analysis showed that age,history of abdominal surgery,white blood cell count,serum sodium,serum potassium,neutrophil percentage,and serum albumin were risk factors for decompensated cirrhosis patients with intestinal obstruction.The results of multivariate analysis indicated that age,history of abdominal surgery,white blood cell count,serum sodium,serum potassium,neutrophil percentage,and serum albumin were independent risk factors for decompensated cirrhosis patients with intestinal obstruction.Conclusion·Decompensated cirrhosis patients with age ≥ 50 years old,a history of abdominal surgery,the abdominal cavity infection,low potassium,hyponatremia,and lower serum albumin are likely to develop the intestinal obstruction.

Objective To understand the vitamin D status and its possible ethnic differences among Uygur and Han women of childbearing age in a community of Urumqi.Methods Based on the data of 2 080 patients with thyroid disease in a community of Urumqi,which were collected in May 2013,we selected the complete information of 652 Uygur and Han women of childbearing age (between 18-45 years),which included 367 Uygur women [average age (35.14± 6.91) years] and 285 Han women [average age (35.52± 7.10) years].The basic data of height,weight,and waist circumference were recorded.The serum level of 25-hydroxyl vitamin D [25(OH) D] was detected by chemiluminescence method.Results The serum 25(OH) D levels of Uygur and Han were (11.51±6.31) μg/L and (16.43±6.43) μg/L,respectively.The 25(OH)D level in Uygur women was significantly lower than that of Han women (t =-9.800,P＜0.001).The constituent ratio of vitamin D status was significantly different between Uygur and Han women (vitamin D severe deficiency:47.4％ in Uygur women and 12.3％ in Han women),deficiency (44.7％ in Uygur women and 64.6％ in Han women),insufficiency 5.7％ in Uygur women and 17.9％ in Han women),sufficiency (2.2％ in Uygur women and 5.2％ in Han women) (x2 =99.486,P＜0.001).Conclusion Serum 25 (OH) D deficiency is common in Uygur and Han women of childbearing age in Urumqi,especially among Uygur women.

Objective To study the prevalence of metabolic syndrome (MS) within the Uyghur people with abnormal glucose metabolism in Xinjiang province according to three different diagnostic criteria and effects of accumulation of MS components on blood lipid profile.Methods Components of MS and blood lipid profile were observed with 666 Uyghur people with abnormal glucose metabolism after cluster randomized sampling method for selecting in Xinjiang province,and analyzed with the recommended diagnostic criteria by the National Cholesterol Education Program-Adult treatment Panel Ⅲ(NCEP-ATP Ⅲ,2001),the Chinese Diabetes Society under Chinese Medical Association (CDS,2004) and the International Diabetes Federation (IDF,2005).Results Prevalence of MS was 21.92％ (14.67％),23.72％ (15.88％),57.51％ (38.48％) with the criteria by NCEP-ATPⅢ,CDS,and IDF,respectively.IDF was the best among three criteria.The most combination was the abnormal glucose metabolism,dyslipidemia and obesity.In the ATPⅢ (2001),with the increase of number of components of metabolic syndrome,highdensity lipoprotein cholesterol (HDL-C) drop,low density lipoprotein cholesterol (LDL-C) increased; there was not significant difference in the CDS.Conclusions The incidence of MS was high in the Uyghur people with abnormal glucose metabolism in Xinjiang province.Most of them complicated with dyslipidemia.One of common components of MS included the elevated triglycerides,decreased HDL-C,and increased size of LDL-C particles,which could easily cause cardiovascular disease.
