Sudden visual loss is a group of diseases of retina, with emotional factors being an important pathogeny. On the basis of summarizing the relationship between the psychological features of the sudden visual loss and seven emotional factors, we explore the application of the seven emotional factors in sudden visual loss, in order to treat a disease by looking into both its body and mind and enhance its therapeutic effects.

Objective To study the relationship between the cerebral artery stenosis and the carotid artery elasticity in the ischemia stroke patients by echo-tracking technique.Methods Ninety-two ischemia stroke patients were divided into both the mild cerebral arteries stenosis and moderate-severe cerebral arteries stenosis groups.CT angiography was performed to evaluate the stenosis of cerebral artery.The changes of the carotid diameter during cardiac cycles were obtained by echo-tracking technique and the quantitative parameters of pressure-strain elastic modulus (Ep),stiffness (β) and arterial compliance (AC) were calculated automatically. Results①There were significant differences (P＜0.05) between the ischemia stroke patient group and the normal adults group in β，Ep and AC.② There were significant differences (P＜0.05) between the mild cerebral arteries stenosis groups and the moderate-severe cerebral arteries stenosis groups in β and Ep.AC was lower in patients with the mild cerebral arteries stenosis groups than that in the moderate-severe cerebral arteries stenosis groups.Conclusions The carotid artery elasticity in ischemia stroke patients were significantly different from normal adults.In the ischemia stroke patients,the stiffer the carotid artery was,the higher the likelihood of moderate-severe cerebral stenosis was.

Objective To observe the impact of the five-emotion restrictive therapy on coronary heart disease. Methods109 hospitalized patients with coronary heart disease were randomly divided into a experimental of 56 patients and a control group of 53 patients according to length of stay. The control group was treated with the conventional therapy; the experimental group was imposed five-emotion restrictive psychological intervention on the basis of conventional therapy. The investigation was done using self-rating anxiety scale(SAS) and self-rating depression scale(SDS) on 1 day after admission and ld before discharge respectively. SAS and SDS scores were surveyed. At the same time Holter monitoring and normal ECG test were compared. Results Compared with control group, the experimental group 1 d before discharge of the SAS and SDS scores were (41.9±7.4) and (38.6±8.4), and the difference was statistically significant (P＜0.01) . The total effective rate of Holter monitoring and normal ECG was 64.15％ and 92.85％ in the control and experimental group, and the difference was significant (P＜0.01) . ConclusionThe pathological seven emotions have a certain affection on the incidence of coronary heart disease, treatment and prognosis of the course. Five-emotion restrictive psychological intervention can adjust timely psychological state of patients, eliminate negative emotions, and significantly help the incidence, treatment and prognosis of the disease.

Objective To understand the implementing situation of prevention measures for iodine deficiency disorders before (2011) and after (2013) the adjustment of salt iodine content in Guangxi,to evaluate the changes of iodine nutritional status,and to provide a basis for future prevention work.Methods Monitoring data of iodized salt,drinking water iodine and iodine nutritional status before and after the adjustment of iodine content of salt was collected.Changes in water iodine,salt iodine and urinary iodine before and after adjusting iodine content of salt were compared.Results The monitoring work of iodized salt,drinking water iodine and iodine nutritional status was carried out in all the 109 counties (cities,districts) in 2011 and 2013.①Drinking water iodine monitoring:a total of 4 968 water samples was tested in 2011,the median water iodine was 2.69 μg/L.Of which,4 210 water samples below 10.00 μg/L,the proportion was 84.74％.A total of 7 554 water samples were tested in 2013,the median water iodine was 2.11 μg/L.Of which,6 512 water samples below 10.00 μg/L,the proportion was 86.12％.②Iodized salt monitoring:a total of 30 786 salt samples were tested in 2011; the salt median iodine was 32.30 mg/kg.The iodized salt coverage rate was 98.31％,iodized salt qualification rate was 97.36％,and qualified iodized salt consumption rate was 95.98％ weighted by population.A total of 32 779 salt samples were tested in 2013; the salt median iodine was 24.94 mg/kg,the iodized salt coverage rate was 98.36％,iodized salt qualification rate was 95.97％,and qualified iodized salt consumption rate was 94.49％ weighted by population.The difference of salt iodine was statistically significant between 2011 and 2013 (x2 =17 830.03,P ＜ 0.05).③Urinary iodine monitoring:a total of 8 278 urinary samples were detected in 2011; the median urinary iodine was 241.10 μg/L.Among these,889 urinary samples below 100.00 μg/L,the proportion was 10.74％; 2 174 urinary samples in 100.00 -＜ 200.00 μg/L,the proportion was 26.26％; 2 451 urinary samples in 200.00-＜ 300.00 μg/L,the proportion was 29.61％; and 2 764 urinary samples ≥300.00 μg/L,the proportion was 33.39％.A total of 10 988 urinary samples were tested in 2013; the median urinary iodine was 200.35 μg/L Among these,1 716 urinary samples below 100.00 μg/L,the proportion was 15.62％; 3 745 urinary samples in 100.00-＜ 200.00 μg/L,the proportion was 34.08％;2 970 urinary samples in 200.00-＜ 300.00 μg/L,the proportion was 27.03％; and 2 557 urinary samples ≥300.00 μg/L,the proportion was 23.27％.The difference of urinary iodine was statistically significant between 2011 and 2013 (x2 =391.98,P ＜ 0.05).Conclusions Guangxi belongs to an area with low iodine level.The situation of iodine deficiency disorders is in accordance with the national Standard to Eliminate Iodine Deficiency Disorders.Scientific salt iodization and sustained elimination of iodine deficiency disorders should continue to ensure appropriate levels of iodine nutrition among residents in Guangxi.

Objective:To learn about the status of iodine deficiency disorders in children and pregnant women in coastal areas of Guangxi Zhuang Autonomous Region (Guangxi for short).Methods:From January 2017 to December 2020, 12 counties (cities, districts) in Beihai City, Qinzhou City and Fangchenggang City in coastal areas of Guangxi were selected as the survey sites to carry out iodine deficiency disorders monitoring. Each county (city, district) was divided into five areas according to administrative regions: East, West, South, North and Middle. One township (town) was selected from each area, and 40 non-boarding children aged 8 to 10 (age balanced, half male and half female) and 20 pregnant women were selected from each township (town) as the survey subjects. Edible salt samples and urine samples were collected from children and pregnant women to detect salt iodine and urinary iodine levels; thyroid volume of children was determined and the rate of goiter was calculated.Results:From 2017 to 2020, a total of 8 905 children were monitored, and the median salt iodine of children was 23.4 mg/kg, and the medians salt iodine in each year were 23.7, 22.8, 23.5, 23.6 mg/kg, respectively; the median urinary iodine of children was 164.7 μg/L, and the medians urinary iodine in each year were 161.2, 169.7, 156.0, 171.1 μg/L, respectively; 30 of them had goiter, the rate of goiter of children was 0.34% (30/8 905). A total of 6 626 pregnant women were monitored, and the median salt iodine of pregnant women was 23.5 mg/kg, and the medians salt iodine in each year were 23.7, 22.5, 24.3, 23.8 mg/kg, respectively; the median urinary iodine of pregnant women was 139.6 μg/L, and the medians urinary iodine in each year were 129.6, 131.6, 134.4, 175.0 μg/L, respectively.Conclusions:The iodine nutrition of children in coastal areas of Guangxi is at an appropriate level (100 - 199 μg/L), and the rate of goiter has reached the national iodine deficiency disorders elimination standard (< 5%). But pregnant women are at risk of iodine deficiency (urinary iodine < 150 μg/L).
