Objective To investigate the prevalence of thyroid nodules and thyroid dysfunction in southern mountainouss areas of Ningxia.Methods A cross-sectional study was conducted among a representative sample of 10 639 adults in Jingyuan county with a population proportionate sampling method.High-resolution ultrasound was used to examine the thyroid and fasting blood specimens were collected in the morning for measurement of TSH,FT4,FT3.Chi-square test and spearman rank correlation analysis were used for statistical analysis.Results The prevalence of thyroid nodules was 29.08％,the sex-and age-adjusted rate was 27.17％.The prevalence of thyroid nodules was higher in women than in men (32.68％ vs.24.88％,x2=76.029 2,P＜0.001) and age was positively associated with thyroid nodules (r=0.272,P＜0.001).The rate of thyroid dysfunetion,subclinical hypothyroidism,subclinical hyperthyroidism,hypothyroidism,hyperthyroidism were 17.39％,13.00％,0.42％,0.96％,3.01％,respectively.The prevalence of thyroid nodules was higher in abnormal TSH group than in normal TSH group (39.44％ vs.27.24％,x2=95.624 0,P＜0.001).The level of THS,FT3,FT4 in thyroid nodules group differed fromn control group (Z=-9.144,P＜0.001;Z=-6.140,P＜0.001;Z=-1.997,P=0.046).Conclusion The prevalence of thyroid nodules and thyroid dysfunction were higher in southern mountainous areas of Ningxia.The relationship between thyroid nodules and thyroid function needs further research.We should pay attention to the early screening and diagnosis of thyroid nodules in mountainous areas.

Objective To investigate the prevalences of the obesity and hypertension in southern mountain regions of Ningxia. Methods A cross-sectional study was conducted among a representative sample of 10 639 adults using questionnaires, physical examinations, and blood pressure measurement in southern mountain areas with a population proportionate sampling method. Results The prevalences of overweight,obesity,central obesity,high percentage of body fat,and hypertension were 33.53%,10.71%,19.50%,27.69%,and 31.57% respectively, which were 30.31%,9.62%,16.70%,24.90%,and 27.61% after age-adjustment in rural areas of Ningxia,and increased with aging(Ptrend<0.05). The prevalences of overweight,obesity,and hypertension were higher in males than those in females(P<0.05),and that of central obesity was higher in females than in males(P=0.003).The prevalences of hypertension in subjects with overweight, obesity, central obesity, high percentage of body fat were 38. 14%, 53.75%,52.69%,and 48.90%,respectively. Body mass index,waist circumference,and percentage of body fat were positively correlated with systolic and diastolic blood pressure(P<0.05). The multivariable logistic model revealed that the risk of hypertension in different types of obesity increased about 1.5 times. Conclusion There is high prevalence of obesity and hypertension among the adults in southern mountain areas of Ningxia. The prevalence of hypertension in obesity,central obesity,and high percentage of body fat is closed to or more than half of the population investigated.

Objective To investigate the correlation between iodine nutritional status and thyroid diseases in some areas of Ningxia. Methods The physical examination, questionnaire survey, and measurement of urine iodine, thyroid function, thyroid associated antibodies were performed, with thyroid ultrasonography in Jingyuan County, Xingqing District and Guyuan City, Ningxia Yinchuan City, totally including 2827 adults. Results The median urinary iodine of all subjects was 258. 7(76. 6-1506. 4) μg/L. The average level of urinary iodine in rural areas [203.3(64. 6-1154)μg/L] was lower than that in cities[340. 7(114. 8-1726. 1)μg/L, Z=19. 514, P>0. 01]. The average urinary iodine level was lower in people over 65 years old[234. 2(58. 9-2285. 4) μg/L, x2=6.449, P=0. 040]. Subjects in hypothyroidism group [232. 5(69. 2-1682. 3) μg/L] had the lowest average urinary iodine level, while hyperthyroidism group[331. 9(102. 4-1862) μg/L] turned to be the highest group( x2=15. 432, P>0. 01). Compared with the normal group, TPOAb and TGAb increased group had similar median levels of urinary iodine (P>0. 05). If compared with single nodule, multiple nodules group and the normal group's median levels of urinary iodine also had no significant difference(P>0. 05). Conclusion Iodine excess was found in the studied population in these areas of Ningxia.

Objective To explore the influence of Yoga exercise on the work stress and coping styles of operating room nurses. Methods A total of 77 nurses were selected working in the operating room of our hospital,and all the nurses were randomly divided into observation group(38 cases)and the control group (39 cases). The nurses of observation group did Yoga exercise regularly,while the nurses of control group did not make any Yoga workout regularly. We used psychological stress scale( CPSS)to assess anxiety of two groups nurses before and after the intervention,and investigated every nurse's pressure coping style respectively before and after care. Results Pressure improvement mark in the observation group had been greatly improved after Yoga exercise intervention(16. 203 ± 4. 218),while it was(3. 127 ± 1. 037)in the control group with statistical significance( t = 3. 012,P < 0. 05);the improvement of anxiety in the observation group was significantly better than that of the control groups,the difference had statistical significance(P < 0. 05);the stress coping style of observation group were obvious improved after the intervention compared with that of the control group(P < 0. 05). Conclusions Yoga exercises can improve the working stress and coping operating room nurses effectively.

Objective:To explore the clinical effects of traditional Chinese medicine (TCM) dialectical feeding in patients with oral lichen planus of spleen and stomach damp-heat type.Methods:From January 2017 to December 2018, we selected 98 patients with oral lichen planus of spleen and stomach damp-heat type who visited the Oral Mucosal Diagnosis and Treatment Center of Integrated Traditional Chinese and Western Medicine in Qingdao Stomatological Hospital, the Affiliated Hospital of Qingdao University. Patients were divided into experimental group and control group by random number table method, each with 49 cases. Two groups adopted the same treatment methods of Chinese and Western medicine, and control group carried out conventional nursing, and experimental group conducted TCM dialectical feeding based on conventional nursing. Both groups had continuous intervention for 8 weeks. The physical sign scores, Visual Analogue Scale (VAS) scores, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores of patients of the two groups were compared before and after treatment.Results:The physical sign scores of the two groups at the fourth and eighth week of intervention were lower than those at the initial diagnosis, and the difference was statistically significant ( P<0.05) . After 8 weeks of intervention, the physical sign score of experimental group was lower than that of control group, and the difference was statistically significant ( P<0.05) . The VAS scores of the two groups at the the fourth and eighth week of intervention were lower than those at the initial diagnosis with a statistical difference ( P<0.05) . After 4 and 8 weeks of intervention, the VAS scores of experimental group were lower than those of control group, and the difference was statistically significant ( P<0.05) . After intervention, the SAS and SDS scores of the two groups were reduced, and that of experimental group was lower than that of control group also with a statistical difference ( P<0.05) . Conclusions:The use of TCM dialectical feeding nursing guidance for patients with spleen and stomach damp-heat type oral lichen planus can improve the patient's disease condition and pain symptoms, and relieve the patient's negative emotion.

Objective To investigate the prevalence of nonalcoholic fatty liver disease and the risk factors in Jingyuan county of Ningxia Autonomous Region.Methods The population proportionate sampling method was applied to enroll a representative sample of 10 639 adults in Jingyuan county and the study was conducted using questionnaires and physical examinations.A total of 10 553 people were included in the analysis after excluding those with missing data.High-resolution ultrasound was used to examine the liver and fasting blood was collected in the morning for measurement of blood glucose,blood lipid,and uric acid.The participants were divided into two groups of those with and without nonalcoholic fatty liver disease;the difference in blood biochemical indexes between fatty liver and non-fatty liver groups was compared,and the logistic regression model was used to explore the risk factors affecting the prevalence of fatty liver.Results The prevalence of nonalcoholic fatty liver disease was 7.60％.The prevalence of thyroid nodules was higher in men than in women (8.60％ vs.6.82％,x2=1 1.772,P=0.001).The prevalence rate of fatty liver increased with age (x2=57.336,P＜0.001),the prevalence rates among ≥18 years-＜29 years,≥30 years-＜39 years,≥40years-＜49 years,≥50 years-＜59 years,≥60 years-＜69 years,and above 70 years were 2.92％,6.50％,8.81％,9.59％,8.08％,and 4.77％ respectively.The detection rate of overweight,obesity,abdominal obesity,impaired fasting glucose,impaired glucose tolerance,diabetes,hypertension,hyperuricemia,and dyslipidemia were higher in nonalcoholic fatty liver disease group than in the normal group (P＜0.05).Logistic regression analysis showed that nonalcoholic fatty liver disease group had a higher risk for overweight,obesity,abdominal obesity,impaired fasting glucose,impaired glucose tolerance,diabetes,hypertension,hyperurcemia,and dyslipidemia (OR=5.41,12.45,2.99,1.85,2.05,3.30,1.41,2.23,and 1.98).Conclusion The incidence of nonalcoholic fatty liver in Jingyuan county of Ningxia Autonomous Region was higher.The groups of overweight,obesity,abdominal obesity,impaired fasting glucose,impaired glucose tolerance,diabetes,hypertension,hyperuricemia,and dyslipidemia were high risk factors for nonalcoholic fatty liver disease.

Objective:To preliminarily estimate and study the effect of nucleic acid testing in blood screening on the residual risk (RR) of transfusion transmitted HBV infection (TTI HBV).Methods:Using the NAT yield/WP ratio model and adopting the relevant data of information management system of practice comparison working party in the Mainland of China, this paper analyzed the trend of the RR of TTI HBV among 18 blood centers from 2015 to 2019 in China, and compared the impact of two kinds of blood screening strategies which were ELISA+ ID-NAT/MP-NAT (individual-donation nucleic acid testing or mini-pool nucleic acid testing) and ELISA + MP-NAT on RR in 2019.Results:The overall trends of the 5-year RR of HBV among 18 blood centers showed by trend chi square test were NAT single positive rate trend χ2= 39.42( P<0.01) and residual risk trend χ2= 279.792( P<0.01); The influence on RR from the differences of ELISA+ ID-NAT/MP-NAT and ELISA+ MP-NAT was statistically significant, and chi square test showed that χ2= 7.4( P<0.01). Conclusions:Since the implementation of nucleic acid testing in the blood screening in China from 2015, the residual risk of transfusion transmitted HBV infection has decreased year by year. The observed two blood screening strategies which dominated in China may lead to discrepancy in the residual risk of TTI.

Objective: To investigate the prevalence of dyslipidemia among adults in the southern mountains of Ningxia Hui Aulonomous Region. Methods: A cross-sectional study was conducted among a representative sample of 10 639 adults in the southern mountains using a population proportionate-sampling method in 2014. Questionnaires were completed and physical and laboratory examinations were performed. A total of 10 172 subjects were included in the analysis after excluding those with missing data. Dyslipidemia was diagnosed according to "Chinese guidelines for the prevention and treatment of dyslipidemia in adults" (2007). Results: The prevalence of dyslipidemia, hypercholesterolemia, hypertriglyceridemia, decreased high-density lipoprotein cholesterol (HDL-C), and increased low-density lipoprotein cholesterol (LDL-C) was 33.90%, 0.30%, 12.52%, 28.53%, and 1.14%, and the age-specific prevalence was 32.42%, 0.29%, 10.97%, 27.70%, and 1.07%, respectively. Borderline high triglycerides and borderline increased LDL-C were found in 13.09% and 6.52% of the study population, respectively. The rates of hypertriglyceridemia, decreased HDL-C, and dyslipidemia were higher in males than in females (P<0.05). The prevalence of dyslipidemia was higher in the group characterized by the risk factors of obesity, hypertension, diabetes, hyperuricemia, smoking, and drinking, compared to those without these factors (P<0.05). Conclusion The prevalence of dyslipidemia was higher in men than in women, and the differences were statistically significant. Hypertriglyceridemia and decreased HDL-C were the two major types of dyslipidemia. Obesity, hypertension, diabetes, hyperuricemia, smoking, and drinking alcohol increased the risk of dyslipidemia.
