Objective To analyze the family burden of the caregivers of the psychosis patients in community, and the psychosocial factors which influence the family burden.Methods Conducted some questionnaires to survey the requirement and attitude on mental health knowledge,social support,family burden and coping style of the caregivers of the psychosis patients from the twelve communities which served as the stations for the psychosis of the twelve prefectures organized uniformly by Guangdong provincial disabled federation.Results 360 questionnaire was provided,and 308 replied to our questionnaire effectively.The mean score of each single item of the family burden questionnaire was beyond the moderate.The factor score of the economy burden was the highest among the factots of the economy burden(2.33±0.52),the daily activity of the family(2.17±0.53),the recreation activity of the family(2.00±0.58),the family relationship(2.10±0.54),the body health of the family members (2.03±0.65),and the mental health of the family members(2.09±0.68).The bad emotion and experience with the patients aggravated some factors of the family burden(P<0.05～0.01).According to correlation analysis and regression analysis,there were significant relation and impact between family burden with the requirement and attitude on mental health knowledge,subject support,coping style,age,economy,culture and so on(P<0.05～0.01). Conclusion Negative assumption to mental health will aggravate the family burden,transfering the positive message and changing passive coping style will help to reduce the family burden.

Objective To observe the functional connectivity (FC) pattern linking the hippocampus with the rest of the brain in ischemic stroke patients with cognitive dysfunction,especially the default mode network (DMN).Methods Resting-state functional connectivity magnetic resonance imaging (fMRI) was performed on 15 ischemic stroke patients with cognitive dysfunction (the patient group) and 10 normal elderly controls.The bilateral hippocampus was the region of interest.Correlation analyses yielded a mapping of cerebral functional connectivity activation for both groups.Results Compared with the healthy controls,the patient group showed weakened functional connectivity between the hippocampus and other regions including the cingulate gyrus,the superior,middle and inferior frontal lobes,the inferior parietal lobule and the superior temporal gyrus.But there was enhanced functional connectivity with the cerebellar posterior lobe,the occipital lobe,the medial temporal lobe,the precuneus and the calcarine.The results were significantly different between the two groups.Conclusion The functional connectivity pattern of the hippocampus is impaired in stroke patients with cognitive dysfunction.Reduced functional connectivity between brain regions may be one cause of cognitive dysfunction after stroke,and enhanced functional connectivity may be an appropriate compensatory mechanism.

Objective To investigate the requirement and the attitude of the mental health knowledge and some psychological factors indifferent developed regions. Methods The mental patients, their caregivers and normal people in total of 534 were surveyed with the Zung'sSelf-rating Depression Scale, the Questionnaire of Experience and Attitude of the Psychosis (self-edited), the Questionnaire of Requirementand Attitude on Mental Health Knowledge (self-edited), the Social Support Rating Scale and the Simplified Coping Style Questionnaire. Theresults were compared between the developed and the developing regions. Results Compared with those from developing, the requirementwas more and the attitude was more positive on mental health knowledge in all the people from the developed regions; the patients obtainedand applied more support, and took more positive coping style, less depressive emotion; the caregivers took more positive and negative copingstyles, and more depressive emotion; the healthy people applied more support, and took more positive coping style; the caregivers feltmore un-safety and wished the patients stay in hospital longer. Conclusion Development of the region plays a role in the mental health. Thecaregivers need more support and care.

ObjectiveTo analyse the requirement and attitude to mental health knowledge and the influence factors among the psychosis patients, the caregivers and the healthy pepople.MethodsThe questionnaire survey conducted among the psychosis patients, the caregivers and the healthy pepople from 12 communities which served as the stations for the psychosis where 12 prefectures were organized uniformly by Guangdong Provincial Federation of Disabled Persons.Results1080 sheets of questionnaire were provided, and 986 replied to meet the requirements. The caregivers showed significant difference in requirment and attitude to mental health knowledge compared to the psychosis patients and the healthy pepople(P＜0.05-0.001). The main influence factors were cultural education, regional economic, the frequency of inpatient, the anxiety emotion of the caregivers, which were statistical significance(P＜0.05-0.001).ConclusionIt is lack in the requirement and cognition to mental health knowledge among the psychosis patients, the caregivers and the healthy pepople. Cultural education and economic development are the effective measures to improve the level of the mental health knowledge.

ObjectiveTo investigate the negative emoion and the relative factors in the caregivers of the schizophrenia patients in community. Methods212 caregivers from 12 communities psychotic service stations in 12 prefectures in Guangdong were investigated with the Zung Self-rate of Depression, the experience and attitude of the psychosis, the requirement and attitude on mental health knowledge, the social support scale, the family burden scale and the simply coping style questionaire. ResultsThere were 112 caregivers with no depression (52.8%), 57 with mild depression (26.9%), 30 with middle depression (14.2%), 13 with severe depression (6.1%). More than 50% caregivers worry about unsafty, getting into trouble, worse reputation, genetics, felt scare, strained relationship with the patients. There were significant differences in the hopelessness, the strained relaionship, treatment in other cities, superstition, hospitalization longer between the depression and no depression group, as well as in the economy burden, the interference in the family living, the amusement of family, the family relaionship, the body health and the mental health of the other family members, but no significant in the factors of the requirement and attitude on mental healh knowledge. The caregivers with depression reported less social support than the caregivers with no depression, but there was no difference between these groups in utilization of support. ConclusionThe caregivers of the schizophrenia patients experience negative emotion in community, who need mental and material assistance and the education of the knowledge about diseases.

Objective To investigate the association between the tumour necrosis factor-α-863(TNF-α-863) polymorphism and gout in Han population from the city of Tangshan.Methods We recruited 80 gout patients and 80 healthy individuals into this study.The polymorphisms of TNF-α-863 site were analyzed by polymerase chain reaction-ligase detection reaction(PCR-LDR).The frequencies of different TNF-α-863 genotypes/alleles were analyzed in the gout group and the control subjects.Results No significant differences were observed in the genotype frequencies(x2=2.8807,P=0.0897) and allelic frequencies(x2=4.2646,P=0.1187) of TNF-α-863 site in the comparison between gout and control groups.Conclusion The result of our study suggests that the polymorphism of TNF-α-863 site may not related to gout in Han population in Tangshan.

Objective To investigate the iodine nutrition level of vulnerable people in Inner Mongolia after adjustment of iodized salt standard and to provide theoretical bases for scientific iodine supplementation. Methods In 2013, 3 cities were selected from eastern, central and western parts of Inner Mongolia in accordance with the random number table, 3 or 4 counties were selected from each target city, 5 units according to their sub-area position of east, south, west, north and center were selected from each county, and then 1 township was selected from each unit, 5 groups of target population including school children aged 8- 10, women of childbearing age, pregnant and lactating women and infants each at least 10 people were investigated in each township. Edible salt samples from their homes and urine samples were collected. The direct titration method among the generic methods of iodide testing for salt production industry (GB/T 13025.7-2012) was used to determine the salt iodine level, and As3+-Ce4+catalytic spectrophotometry using ammonium per sulfate digestion (WS/T 107-2009) was used to test the urinary iodine level. Results Totally 3 300 samples of edible salt from local residents had been examined and median iodine was 26.20 mg/kg. The median of urinary iodine was 190.6μg/L of 1 289 school-age children;was 183.6μg/L of 621 women of childbearing age; was 178.2 μg/L o f 876 pregnant women; was 178.6 μg/L of 664 lactating women and was 167.7μg/L of 599 infants. Conclusion After adjustment of iodized salt standard, iodine nutrition level is suitable in all vulnerable people.

Objective To understand the current iodine nutritional status of pregnant women in Inner Mongolia, and provide scientific basis for iodine supplementation during pregnancy. Methods In 103 banners (counties, cities and districts) of Inner Mongolia Autonomous Region, 5 townships were randomly selected according to their sub-area positions of east, west, south, north and center in each banner (county, city and district) in 2018. Twenty pregnant women in each township were sampled to collect edible salt and a random urine samples. The iodine in salt was determined by direct titration. Urinary iodine was detected by As3+-Ce4+catalytic spectrophotometry. According to different pregnancy, maternal age and regional type, the iodine nutrition level of pregnant women was analyzed. Results Totally 9809 pregnant women were investigated, the median of salt iodine was 23.4 mg/kg, iodized salt coverage rate was 98.03％(9616/9809), qualified iodized salt consumption rate was 93.32％(9154/9809), and the median of urinary iodine was 167.20 μg/L. Between different pregnancy and different age groups, there were no significant differences in qualified iodized salt consumption rate (P > 0.05). But the difference between different regions was statistically significant(P<0.05). Between different age groups, there was no significant difference in the median of urinary iodine(P > 0.05). In both different pregnancy and different regions, there were statistically significant differences between groups (P < 0.05). Conclusions The current iodine nutrition level of pregnant women in Inner Mongolia is suitable to meet the physiological needs of themselves, and the fetus. But pregnant women in different regions have different levels of iodine nutrition.

Objective:To study the iodine nutrition status of children in non-high water iodine areas of Inner Mongolia Autonomous Region, analyze the monitoring results of iodine deficiency disorders, so as to provide a basis for further guidance on scientific iodine supplementation for children in Inner Mongolia Autonomous Region.Methods:According to the requirements of the National IDD Monitoring Program and the IDD Monitoring Program of Inner Mongolia in 2021, cluster sampling method was used to select non boarding children aged 8 - 10 from 104 counties (cities, districts) in 12 cities within the jurisdiction of Inner Mongolia Autonomous Region. Random urine samples and household salt samples were collected to detect iodine content. At the same time, 1/3 of the selected children were selected for thyroid B-ultrasound examination to measure thyroid volume.Results:In 2021, a total of 19 968 children aged 8 - 10 in non-high water iodine areas of Inner Mongolia were monitored, and 19 968 urine samples were collected, with a median urine iodine of 199.23 μg/L. There was a statistically significant difference in the frequency distribution of urinary iodine in different cities (χ 2 = 839.51, P < 0.001). The median iodine content of children's household edible salt was 22.64 mg/kg, and the coverage rate of iodized salt, qualified iodized salt coverage rate, and non-iodized salt rate in the entire region was 99.05% (19 778/19 968), 94.98% (18 785/19 778), 94.08% (18 785/19 968) and 0.95% (190/19 968), respectively. Thyroid B-ultrasound were performed in 6553 children, the goiter rate was 1.30% (85/6 553), and there were statistically significant differences in goiter rates among children of different ages and cities (χ 2 = 87.09, P < 0.001; χ 2 = 10.40, P = 0.006) . Conclusions:In 2021, the iodine nutrition of children aged 8 - 10 in non-high water iodine areas of Inner Mongolia is at an appropriate level. However, in the future we should continue to adhere to the monitoring of iodine deficiency disorders, strengthen health education on iodine deficiency disorders, consolidate existing achievements in iodine deficiency disease prevention and control, and achieve the goal of continuous elimination of iodine deficiency disorders.

Objective:To explore the prevalence and risk factors of thyroid diseases in the physical examination population of Hohhot.Methods:From July 2017 to July 2018, 3 100 health examinees from Inner Mongolia National Examination Medical Center were selected as subjects for questionnaire survey, thyroid function test and thyroid ultrasound examination; a multinomial logistic regression model was used to analyze the relationship between relevant investigation factors and different types of thyroid diseases (simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules).Results:Among the 3 100 healthy examinees, there were 2 885 effective responders, including 743 males and 2 142 females, aged (46.23 ± 12.32) years; the simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules were 909, 648, and 619 cases, respectively, and the detection rates were 31.51%, 22.46%, and 21.46%, respectively. Logistic regression analysis results showed that age [35 - 54 years old: odds ratio ( OR) = 1.30, 95% confidence interval ( CI): 1.01 - 1.68; ≥55 years old: OR = 2.30, 95% CI: 1.68 - 3.14, P < 0.05], gender ( OR = 1.65, 95% CI: 1.32 - 2.07, P < 0.05), obesity ( OR = 1.35, 95% CI: 1.08 - 1.70, P < 0.05), and mental stress [significant: OR = 1.64, 95% CI: 1.09 - 2.48; some: OR = 1.54, 95% CI: 1.02 - 2.32, P < 0.05] were the risk factors affecting the occurrence of simple thyroid nodules. The age (35 ~ 54, ≥55 years old), gender, bad mood (a little), and mental stress (significant) were risk factors that affected the occurrence of simple thyroid dysfunction; eating high iodine food was its protective factor. The age (35 ~ 54, ≥55 years old), gender, obesity, and thyroid family genetic history were risk factors for thyroid dysfunction with nodules; the consumption of iodized salt was its protective factor. Conclusions:Older women are high-risk groups for thyroid diseases. Obesity, bad mood, mental stress will increase the risk of the disease. Daily consumption of iodized salt and moderate consumption of high iodine food can reduce the risk of the disease.
