ABSTRACT
Objective:To observe the morphological characteristics of internal carotid artery (ICA) siphon and ophthalmic artery (OA) in patients with non-arteritic anterior ischemic optic neuropathy (NAION) based on CT angiography (CTA) three-dimensional reconstruction of ICA siphon and OA models.Methods:A retrospective cohort study. From January 2017 to January 2019, 26 patients with 31 eyes (NAION group) who were diagnosed with NAION by ophthalmic examination at Beijing Friendship Hospital, Capital Medical Universitywere included in the study. Among them, there were 11 males with 13 eyes, and 15 females with 18 eyes; the age was 67.52±6.30 years old. Nineteen eyes of 19 non-affected contralateral eyes were selected as the contralateral eye group. Among them, there were 9 males with 9 eyes and 10 females with 10 eyes; the age was 65.95±5.66 years old. Twenty-six eyes of 26 age- and sex-matched subjects with normal fundus examination during the same period were selected as the normal control group. All subjects underwent best corrected visual acuity (BCVA), intraocular pressure, fundus photography and CTA examination. The data obtained from CT scans were reconstructed by 3D model, and the anatomical morphology of ICA siphon was divided into U-shape, V-shape, C-shape and S-shape; the diameter of ICA siphon portion and the diameter at the beginning of OA were measured. One-way analysis of variance was used to compare the diameter of the OA at the beginning of the OA and the diameter of the ICA siphon between the three groups of eyes.Results:The diameters at the beginning of OA in the NAION group, the contralateral eye group, and the normal control group were 1.17±0.20, 1.34±0.17, and 1.39±0.15 mm, respectively, and the differences among the three groups were statistically significant ( F=12.325, P<0.05); there was no significant difference between the contralateral eye group and the normal control group ( P=0.310). In the NAION group, the anatomical morphology of the ICA siphon was U-shaped and V-shaped in 20 (64.52%) and 8 (25.81%) eyes respectively, and S and C-shaped in 3 eyes (9.67%); in the contralateral eye group, in the control group, the ICA siphon shape of the eyes examined was U-shaped and V-shaped, and S-shaped and C-shaped were rare. The diameters of the ICA siphons in the NAION group, the contralateral eye group, and the normal control group were 3.50±0.69, 3.22±0.59, and 3.55±0.54 mm, respectively. There was no significant difference between the three groups ( F=1.860, P=0.163). Conclusion:U-shaped and V-shaped ICA siphons are more common in NAION-affected eyes; the diameter of the starting point of OA is significantly reduced.
ABSTRACT
Objective:To analyze the characteristics of thyroid diameter and volume of children aged 8 - 10 years in Gansu Province, and to provide a basis for standardizing B-ultrasound examination of children's thyroid volume and establishing a normal reference value of children's thyroid volume.Methods:The data of thyroid volume by B-ultrasound and urinary iodine determination of children aged 8 - 10 years in Gansu Province were from Institute of Endemic Disease, Gansu Center for Disease Control and Prevention. Based on the measured data of thyroid B-ultrasound of 8 - 10 years children in Gansu Province, the characteristics and relationship between thyroid diameter and volume were analyzed by nonparametric test.Results:The medians of urinary iodine of 8, 9, 10 years children ( n = 500, 503, 496) were 166.62, 167.16 and 178.78 μg/L, respectively. The length, width, thickness and volume of the left and right lobes of the thyroid in children were skewed distribution. There was a positive correlation between the left and right diameters (length, width and thickness) and between left and right thyroid volumes ( r = 0.76, 0.85, 0.72, 0.88, P < 0.001). There was no significant difference in the six diameter lines and volume values of thyroid between genders ( P > 0.05), but there was significant difference between ages ( P < 0.001). The means thyroid volume of 8, 9 and 10 years children were 2.6, 2.9 and 3.2 ml, respectively, the medians were 2.5, 2.7 and 3.0 ml, respectively, and the 97th percentile ( P97) were 4.4, 4.9 and 6.5 ml, respectively. The thyroid volume of 10 years group was higher than the current national standard (6.0 ml). The median ranges of thyroid volume of children aged 8, 9 and 10 years at the county level were from 1.8 ml to 4.1 ml, from 1.8 ml to 4.3 ml and from 1.9 ml to 4.4 ml, respectively. There was significant difference in thyroid volume of children at the county level in all age groups ( P < 0.05). Conclusions:Compared with the national standard, the P97 value of thyroid volume of children aged 8 - 10 years in Gansu Province is slightly different. The reference value of thyroid volume should be formulated according to age, and a unified reference value can be used for different genders at the same age.

The contents of the survey included basic information of the patients, clinical diagnosis classification, disease information, surgery and drug treatment, etc.Results:A total of 23 909 patients with Kaschin-Beck disease were diagnosed in 37 counties (districts) of 7 cities (states). The patients with grade Ⅰ, grade Ⅱ and grade Ⅲ accounted for 64.04% (15 312 cases), 26.12% (6 244 cases) and 9.84% (2 353 cases), respectively; 90.74% (21 694 cases) of the patients were over 50 years old, Han nationality was 97.15% (23 228 cases), and peasants were 99.25% (23 729 cases). The patients mainly had multiple joint thickening and deformation (89.30%, 21 350 cases) and pain (87.04%, 20 810 cases). Joint thickening and deformation and pain were more common in finger joint, knee joint and ankle joint. The thickening and deformation of the three joints accounted for 89.97% (21 512 cases), 78.18% (18 692 cases) and 63.81% (15 257 cases), respectively; pain accounted for 80.66% (19 285 cases), 78.75% (18 828 cases) and 64.50% (15 422 cases), respectively; 83.83% (20 044 cases) had joint rest pain, 82.63% (19 757 cases) had joint movement pain and 76.03% (18 177 cases) had joint morning stiffness. Surgical treatment was completed in 1.97% (470 cases). Long-term drug treatment (more than 6 months in the whole year) accounted for 47.78% (11 424 cases); the annual cost of drug treatment was mainly less than 500 yuan, accounting for 57.72% (13 800 cases).Conclusions:The quality of life of patients with Kaschin-Beck disease in Gansu Province is low. We should pay more attention to adult patients with Kaschin-beck disease and strengthen management and treatment.
ABSTRACT
Objective:To observe the changes of optic disc structure in patients with high myopia and the correlation with the morphological markers of the fundus.Methods:A retrospective study. From July 2018 to January 2020, 90 patients (155 eyes) diagnosed as high myopia in Department of Ophthalmology of Beijing Friendship Hospital affiliated to Capital Medical University were included in the study. Among them, there were 31 males (52 eyes) and 59 females (103 eyes), with age of 57.1±14.2 years old and axial length (AL) of 28.5±2.6 mm. According to the classification of myopic macular degeneration, patients were divided into 4 groups based on forms and degree of lesions, including non-pathological myopia group, mild traction lesions group, severe traction lesions group and neovascular lesions group, 35, 58, 41, 21 eyes, respectively. The digitized fundus photographs and an Image J system were used to measure the horizontal, vertical, maximal, and minimal diameter of the optic disc, the horizontal and vertical diameter of the parapapillary δ zone and γ zone, ovality index, distance between the most superior point of the temporal superior arterial arcade and most inferior point of the temporal inferior arterial arcade (VDA), angle between the temporal arterial arcade and optic disc (angle kappa), distance between the optic disc center and the fovea (DFD), angle between the horizontal disc axis and the disc-fovea line (DFA). The correlation between the diameter of the optic disc and other parameters was analyzed. Univariate and multivariate analysis were used to compare differences between groups.Results:The horizontal diameter of the optic disc was positively correlated with the horizontal diameter of the δ zone ( r=0.300, P<0.001), Kappa angle ( r=0.260, P=0.003), and elliptic index ( r=0.650, P<0.001); it was negatively correlated with DFD ( r=-0.190, P=0.030). Optic disc vertical diameter and optic disc horizontal diameter ( r=0.280), δ-zone horizontal diameter ( r=0.330) and vertical diameter ( r=0.460), γ-zone horizontal diameter ( r=0.430) and vertical diameter ( r=0.390), DFD ( r=0.390) was positively correlated ( P<0.001); it was negatively correlated with DFA ( r=-0.210, P=0.001) and Kappa angle ( r=-0.210, P=0.004). Compared with the non-pathological myopia group, there were statistically significant differences in the horizontal and vertical diameters of the optic disc in the severe traction disease group ( P<0.05). Among them, the horizontal diameter difference did not depend on the eye axis and age difference; the vertical diameter difference was caused by the eye axis difference. Compared with the non-pathological myopia group, the difference in the horizontal diameter of the optic disc in the neovascular disease group was statistically significant ( P<0.05), and did not depend on the difference in the axis and age; the difference in the vertical diameter of the optic disc was not statistically significant ( P>0.05). Conclusion:The morphology of optic disc was related to several fundus morphological markers, which was differentiated according to the age, AL and the degree of disease in patients with high myopia.
ABSTRACT
Objective:To describe the characterization of ocular changes secondary to hemophagocytic lymphohistiocytosis (HLH).Methods:The clinical data of 5 patients with HLH complicated with ocular involvement treated in Beijing Friendship Hospital Affiliated to Capital Medical University from September 2020 to May 2021 were retrospectively analyzed, the patients′ systemic examination and treatment were sorted out, and the ocular examination results were analyzed. The relevant literatures on ocular involvement of HLH patients were searched in China National Knowledge Infrastructure (CNKI), Pubmed, WOS, Embase and Medicine databases to summarize the characteristic manifestations of ocular involvement of HLH.Results:Of the 5 patients, 1 had primary HLH, 3 were Epstein-Barr virus-associated HLH (EBV-HLH), and 1 had diffuse large B-cell lymphoma-associated HLH. 4 patients showed unilateral or bilateral focal retinal hemorrhage and exudates. 1 male patient performed bilateral retinal pigment epithelial detachment. The literature search results showed that a total of 1 paper on ocular involvement in HLH patients was retrieved from the Chinese database and 11 papers were retrieved from the foreign database. HLH mainly involved the optic nerve, retina and choroid.Conclusions:The ocular involvement of HLH is easy to be missed or misdiagnosed because of its occult onset and complex and diverse clinical manifestations. Early examination and effective treatment may save vision and avoid missing the opportunity of systemic treatment.
ABSTRACT
Objective:To study the iodine nutritional status and thyroid function of adult males in iodine nutrition appropriate rural areas of Gansu Province.Methods:In 2017, Liangzhou District and Linze County of Gansu Province with suitable children iodine nutrition were selected as the study areas and 52 males aged 20 - 49 years old were investigated in each study area. One random urine sample was collected to determine urinary iodine. Fasting blood samples were collected to determine serum thyroid-stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxin (FT 4), thyroglobulin antibody (TgAb) and thyroid microsomal antibody (TMAb). At the same time, thyroid examination was performed by B-ultrasound. Results:The median urinary iodine of adult males in Liangzhou District and Linze County was 180.2 and 161.0 μg/L, respectively, and the difference was statistically significant ( P < 0.05). There was no goiter in adult males in Liangzhou District and Linze County. The serum TSH (median), FT 3 and FT 4 (mean value) of adult males in Liangzhou District and Linze County were 1.85, 1.61 mU/L, 5.19, 5.16 pmol/L and 16.58, 16.30 pmol/L, respectively. There were no significant differences between the two areas ( P > 0.05). The overall abnormal rate of thyroid function in the two areas was 6.7% (7/104), mainly subclinical hypothyroidism (6/7). The incidences of thyroid dysfunction in Liangzhou District and Linze County were 5.8% (3/52) and 7.7% (4/52), respectively, with no statistical difference between the two areas ( P > 0.05). The total positive rate of antibody was 12.5% (13/104). The positive rates of antibody in Liangzhou District and Linze County were 13.5% (7/52) and 11.5% (6/52), respectively, with no statistical difference between the two areas ( P > 0.05). Both TgAb and TMAb were positive in 9/13 of antibody positive persons, of which the proportion of antibody positive persons in Liangzhou District and Linze County were 7/7 and 2/6, respectively. The 11/13 of the total antibody positive persons were simple antibody positive without thyroid hormone and TSH abnormalities. Conclusion:The iodine nutrition of adult males in iodine nutrition appropriate rural areas of Gansu Province is suitable, but there is a potential risk of thyroid disease in this population, which should be paid attention to and checked regularly.
ABSTRACT
Objective:To investigate the iodine nutritional status of population in Gansu Province, and to provide a scientific basis for policy adjustment of relevant departments.Methods:In 2019, a cross-sectional survey was conducted in 87 monitoring units in 86 counties (districts and cities) of 14 cities (prefectures) in Gansu Province for iodine deficiency disorders (IDD). Instant urine samples and salt samples of children aged 8 to 10 years and pregnant women were collected for detection of urinary iodine and salt iodine. B-ultrasound was used to check the thyroid volume of children in 40 monitoring units.Results:A total of 17 772 children aged 8 to 10 years were investigated. The median urinary iodine (MUI) of children was 197.4 μg/L, the MUI of 14 cities (prefectures) ranged from 160.6 to 233.4 μg/L. There were statistically significant differences in MUI among children of different genders and ages ( P < 0.001). Totally 8 269 children were examined by B-ultrasound, the children's goiter rate was 1.4% (118/8 269). There were statistically significant differences in the thyroid volume among children of different genders and ages ( P < 0.05). A total of 8 605 pregnant women were investigated. The MUI of pregnant women was 178.6 μg/L, and the MUI of 14 cities (prefectures) ranged from 156.5 to 275.0 μg/L. There was no statistical significant difference in MUI among pregnant women in different pregnancies ( P > 0.05). A total of 26 377 samples of salt consumed by children and pregnant women were detected. The median salt iodine was 24.71 mg/kg. The coverage rate of iodized salt and the consumption rate of qualified iodized salt were 99.44% and 93.59%, respectively. Twenty-three counties (districts and cities) failed to meet the elimination standard of IDD in the single indicator. Conclusions:IDD is in a state of continuous elimination in Gansu Province; iodized salt supervision needs to be further strengthened; there is an imbalance of control measures between regions.
ABSTRACT
Objective:To explore the status of kinesiophobia in patients with heart failure during discharge transition period, and analyze its changing trend and influencing factors.Methods:The189 patients with heart failure treated in Henan Provincial People′s Hospital from February 2020 to April 2021 were conveniently selected as the research objects. The general situation questionnaire, the Tampa Scale for Kinesiophobia Heart, the Self-efficacy for Exercise Scale and the Control Attitudes Scale-Revised were used to investigate the patients 2-3 days before leaving the hospital, 1 month and 4 months after discharge.Results:The score of patients′ kinesiophobia deteriorated slightly from 2-3 days before discharge (48.62 ± 11.26) to 1 month after discharge (49.03 ± 11.24), and decreased with the extension of the transition time to 4 months after discharge (47.86 ± 11.11). The overall trend of improvement was statistically significant ( F = 17.92, P<0.01). The score of perceived disease control also showed the same change pattern, 2-3 days before discharge (27.34 ± 7.40), 1 month after discharge (26.18 ± 7.39), 4 months after discharge (27.76 ± 7.38), the difference was statistically significant ( F = 38.41, P<0.01). The score of the exercise self-efficacy of 4 months after discharge (35.63 ± 11.51) was higher than (34.00 ± 11.88) of 2-3 days before discharge and (34.20 ± 11.69) of 1 month after discharge ( F = 12.33, P<0.01). The generalized estimation equation showed that exercise self-efficacy ( B = -0.255, P<0.01) and perceived disease control ( B = -0.439, P<0.01) were protective factors of kinesiophobia in patients with heart failure. Path analysis showed that perceived disease control could not only directly predict patients′ kinesiophobia ( β = -0.461, P<0.01), but also indirectly affect patients′ kinesiophobia by acting on exercise self-efficacy (mediating effect = -0.21, 95% CI -0.293 - -0.136). The mediating effect accounted for 31% of the total effect. Conclusions:The kinesiophobia, perceived disease control and exercise self-efficacy in patients with heart failure during discharge transition were dynamic. Perceived disease control could not only directly predict patients′ kinesiophobia, but also indirectly affect it by acting on exercise self-efficacy. Nursing staff can develop nursing interventions based on perceived disease control or exercise self-efficacy to reducethe level of kinesiophobia inheart failure patients.

Objective:To master the epidemic trend of Kashin-Beck disease (KBD) in Gansu Province and provide a scientific basis for prevention and treatment of KBD.Methods:All children aged 7 - 12 or 16 years old were selected as the survey subjects in 37 KBD districts and counties in Gansu Province, clinical and X-ray monitoring results of KBD in children from 2004 to 2018 were collected to analyze the epidemic trend of the disease.Results:From 2004 to 2018, a total of 97 190 children were examined clinically and 94 180 X-ray films were taken in Gansu Province. Four hundred and twenty-eight clinical positive cases were detected, with a detection rate of 0.44%. There were 649 X-ray positive cases, and the detection rate was 0.69%. There were 435 metaphyseal positive cases, the detection rate was 0.46%. There were 214 positive cases of bone end, and the detection rate was 0.23%. The clinical positive rate was the highest (7.17%, 58/809) in 2004, followed by 2007 (4.60%, 51/1 109) and 2005 (4.48%, 187/4 173), and the positive rate in other years was less than 3%. The positive rate of X-ray was the highest (9.59%, 58/605) in 2004, followed by 2005 (5.10%, 213/4 173), 2008 (3.66%, 45/1 228) and 2006 (3.04%, 125/4 107), the positive rate of other years was less than 3%.Conclusions:The clinical positive rate and X-ray positive rate of KBD in children in Gansu Province are decreased rapidly and then maintain a low fluctuation. The effect of comprehensive prevention and control measures is remarkable.
ABSTRACT
Objective:To evaluate the reliability and validity of the Chinese version of concise health status questionnaire (SF-36 scale) in evaluating the quality of life of patients with chronic Keshan disease, and to provide a scientific basis for studying the quality of life and the evaluation of treatment and rehabilitation of this population.Methods:In the August 2017, using cluster random sampling method, 175 patients with chronic Keshan disease treated by self-management of family beds in Pingliang City, Gansu Province in 2017 were selected as survey subjects, and demographic and disease data were collected. The Chinese version of SF-36 scale was used to investigate the quality of life. Split-half reliability and Cronbach's α coefficient were used to evaluate the reliability of the SF-36 scale; the factor analysis, correlation and differences between groups were used to evaluate the validity of the SF-36 scale.Results:The split-half reliability value of SF-36 scale was 0.916, and the Cronbach's α coefficient was 0.869. Factor analysis extracted 3 common factors from 8 dimensions of SF-36 scale, and the cumulative contribution rate of the 3 common factors to the total variance was 72.08%. In addition to the correlation coefficient ( r) between Role-Emotional and Bodily Pain dimension, the r value between total score and the scores of each dimension, and the scores of each dimension of SF-36 scale were 0.140 - 0.769. Except for the Bodily Pain dimension, there were statistically significant differences in the scores of Physiological Functioning, Role-Physical, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health dimension of the quality of life of patients with different grades of cardiac function ( F = 4.66, 10.73, 6.77, 14.61, 5.58, 9.57, 7.10, P < 0.05). Conclusion:The Chinese version of SF-36 scale has good reliability and validity in evaluating the quality of life of patients with chronic Keshan disease, and can be used to evaluate the quality of life of the patients.
ABSTRACT
Objective:To evaluate the efficacy and safety of enteral extended biliary stenting for biliary stricture.Methods:A multicenter retrospective cohort study was conducted on data of 550 patients with obstructive jaundice due to extrahepatic bile duct stricture between February 2006 and April 2020. Patients were assigned to conventional group (undergoing conventional biliary stent placement) and extended group (undergoing enteral extended biliary stent placement). Propensity score was used to match the basic data of patients of the two groups. Then the stent patency time, bilirubin difference before and after 1 week operation, incidence of complications and hospital stay were compared between the two groups.Results:Among the 550 patients, clinical data of 20 cases were missing and 35 failed to be followed up. Finally, 326 patients were enrolled to the study after propensity score matching with 163 cases in each group. The patency time of extended group was 111.0 (82.0, 192.0) days, which was longer than that of conventional group with patency time of 93.0 (70.0, 141.8) days ( Z=3.260, P=0.001). Total bilirubin difference value of pre-operation and post-operation was less in extended group [51.2 (26.0, 114.7) μmol/L VS 46.0 (13.9, 81.1) μmol/L, Z=2.095, P=0.036]. The rate of early adverse events [4.3% (7/163) VS 3.7% (6/163), P=0.079] and median in-patient days (10.0 days VS 10.0 days, P=0.379) were similar in the two groups. Conclusion:Enteral extended biliary stent is effective and safe for treatment of biliary stricture, which can prolong the patency time without increasing postoperative complications and hospital stay.
ABSTRACT
Objective:By investigating the cognitive level and influencing factors of heart failure knowledge in patients with chronic Keshan disease, so as to provide reference for improving the cognitive level of disease-related knowledge of the patients with Keshan disease in the targeted manner.Methods:In 2019, 100 patients with chronic Keshan disease were selected in Jingchuan County, Gansu Province. A questionnaire survey was conducted using the heart failure knowledge questionnaire to conduct correlation and regression analysis on the cognitive level of patients' heart failure knowledge and influencing factors.Results:Patients' average score of the heart failure knowledge level was (6.18 ± 2.72) points, and the scoring accuracy rate was 41.20%. The Spearman correlation analysis indicated that heart failure knowledge level was associated with annual family income ( r = 0.363, P < 0.01), the hospitalization times due to heart failure ( r = 0.304, P < 0.01), and the number of family members ( r = 0.240, P < 0.05). The results of multiple linear regression showed that the cognitive level of heart failure knowledge in male patients was higher than that in female patients ( P < 0.05). The more hospitalization times ( P < 0.05) and the more family members ( P < 0.05) were, the higher the cognitive level of heart failure knowledge was. Conclusions:The cognitive level of heart failure knowledge of patients with chronic Keshan disease is generally low. Medical staff should actively make use of the patient's hospitalization time for health education, and pay attention to the health education of family members of the patients.
ABSTRACT
Objective:To investigate the application and problems existing in the implementation of the standard of "Assessment for Therapeutic Efficacy of Kashin-Beck Disease" (WS/T 79-2011, referred to as new standard), and to provide technical basis and suggestions for further improving the standard.Methods:In 2019, a questionnaire survey was conducted and analyzed in Sichuan, Shaanxi, Qinghai and Gansu provinces and Tibet Autonomous Region on basic information, standard implementation, publicity, training and application of scoring method of joint dysfunction index of Kashin-Beck disease prevention and control technicians.Results:One hundred and thirty-four questionnaires were distributed in this survey and 132 valid questionnaires were recovered, of which 88.64% (117/132) of Kashin-Beck disease prevention and control technicians received training in the new standard and 89.39% (118/132) used the new standard; 78.03% (103/132) thought that the standard terms were clear and easy to master; 71.97% (95/132) thought it was simple, convenient and easy to operate; 49.24% (65/132) thought that the standard evaluation results were consistent with the actual improvement of patients, and 50.75% (67/132) thought that it was generally consistent; 72.73% (96/132) thought that the design was scientific, reasonable and feasible. When using the scoring method of joint dysfunction index, more than 90% of the technicians thought that the five index terms of "joint rest pain", "joint movement pain", "morning stiffness", "maximum walking distance" and "limb activity ability" were easy to understand and ask questions. When patients with Kashin-Beck disease were investigated, the constituent ratios of easy to understand the five index terms were 96.21% (127/132), 83.33% (110/132), 90.15% (119/132), 78.79%(104/132), 90.15%(119/132) and the constituent ratios of easy to answer were 95.45% (126/132), 83.33% (110/132), 89.39% (118/132), 75.00% (99/132) and 89.39% (118/132), respectively.Conclusions:The new standard terms are clear, the design is scientific and reasonable, the operation is convenient and the feasibility is strong. The evaluation results are basically consistent with the actual improvement of patients. It is suggested to add objective evaluation indexes to the scoring method of joint dysfunction index.
ABSTRACT
Objective@#To evaluate microstructural damage in high myopia (HM) patients using 3T diffusion kurtosis imaging (DKI). @*Materials and Methods@#This prospective study included 30 HM patients and 33 age- and sex-matched healthy controls (HCs) with DKI. Kurtosis parameters including kurtosis fractional anisotropy (FA), mean kurtosis (MK), axial kurtosis (AK), and radial kurtosis (RK) as well as diffusion metrics including FA, mean diffusivity, axial diffusivity (AD), and radial diffusivity derived from DKI were obtained. Group differences in these metrics were compared using tract-based spatial statistics. Partial correlation analysis was used to evaluate correlations between microstructural changes and disease duration. @*Results@#Compared to HCs, HM patients showed significantly reduced AK, RK, MK, and FA and significantly increased AD, predominately in the bilateral corticospinal tract, right inferior longitudinal fasciculus, superior longitudinal fasciculus, inferior fronto-occipital fasciculus, and left thalamus (all p < 0.05, threshold-free cluster enhancement corrected). In addition, DKI-derived kurtosis parameters (AK, RK, and MK) had negative correlations (r = -0.448 to -0.376, all p < 0.05) and diffusion parameter (AD) had positive correlations (r = 0.372 to 0.409, all p < 0.05) with disease duration. @*Conclusion@#HM patients showed microstructural alterations in the brain regions responsible for motor conduction and visionrelated functions. DKI is useful for detecting white matter abnormalities in HM patients, which might be helpful for exploring and monitoring the pathogenesis of the disease.
ABSTRACT
ObjectiveTo investigate the risk factors for failure in emergency endoscopic injection sclerotherapy (EIS) combined with sequential histoacryl injection (HI) for esophagogastric variceal bleeding (EGVB) with portal vein embolus (PVE). MethodsA total of 109 EGVB patients with PVE who underwent emergency gastroscopy in Beijing Shijitan Hospital, Capital Medical University, and The Fifth Medical Center of Chinese PLA General Hospital from January 2018 to December 2019 were enrolled, and according to the outcome of hemostatic treatment under emergency gastroscopy, the patients were divided into hemostatic failure group with 28 patients and hemostatic success group with 81 patients. The two groups were compared in terms of general information, varices and bleeding manifestations under gastroscopy, blood biochemical parameters, Child-Pugh class, and Model for End-Stage Liver Disease (MELD) score, and the risk factors for hemostatic failure were analyzed. The t-test or the Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; a logistic regression analysis was used for multivariate analysis. ResultsCompared with the hemostatic success group, the hemostatic failure group had significantly higher peripheral white blood cell count (WBC), total bilirubin (TBil), Child-Pugh class, and MELD score (Z=3.794, Z=4.751, χ2=40.104, Z=6.412, all P＜0001) and significantly lower prothrombin time activity (PTA), albumin (Alb), and cholinesterase (CHE) (t=9.653, Z=3.093, Z=4.092, P＜0.001, P=0.002, and P＜0.001). WBC (odds ratio ［OR］=28.543, 95% confidence interval ［CI］: 1.285-634.113, P＜0.05), PTA(OR=0.194, 95%CI: 0.045-0.835, P＜0.05), TBil (OR=2.197, 95%CI: 1.004-4.810, P＜0.05), Alb (OR=0448, 95%CI: 0.209-0.961, P＜0.05), and Child-Pugh class (OR=5.164, 95%CI: 1.307-20.406, P＜0.05) were independent risk factors for hemostatic failure. ConclusionWBC, PTA, TBil, Alb, and Child-Pugh class are independent risk factors for failure in emergency EIS combined with sequential HI in the treatment of EGVB with PVE, and adequate preoperative evaluation and correction may help to improve the success rate of hemostasis.
ABSTRACT
Objective:To evaluate the iodine level of drinking water in different ecological regions in Gansu Province, and to provide a basis for preventing iodine deficiency disorders in accordance with local conditions.Methods:In May to July 2017, according to different topography, landforms and climatic conditions, Gansu Province was divided into six ecological regions: desert area, Hexi Corridor gobi area, Loess Plateau hilly area, Qinling Zhongshan gorge area, Gannan Plateau grassland and meadow area, and Loess Plateau gully area. One county was selected from each of the five districts in the east, west, south, north, and central areas in each ecological regions. Drinking water samples were collected in each county based on the township, and the water iodine content was determined by arsenic-cerium catalytic spectrophotometry.Results:A total of 4 037 water samples were collected in 527 townships of six ecological regions, the water iodine range was 0.10 - 97.60 μg/L, with a median of 2.10 μg/L. Among them, the medians water iodine of the six ecological regions were less than 40 μg/L, the difference between different ecological regions was statistically significant ( H = 1 007.440, P < 0.01); the unified centralized, partially centralized and dispersed water supply water samples were 157, 2 263 and 1 617, and the medians water iodine were 1.61, 2.42, and 1.83 μg/L, respectively, and there was statistically significant difference among different water supply methods ( H = 37.164, P < 0.01). Stratified by water supply method, the differences in water iodine between different ecological regions of the same water supply method were statistically significant ( H = 32.628, 580.630, 391.070, P < 0.01); stratified by ecological region type, the differences of different water supply methods in desert area, Hexi Corridor gobi area, Qinling Zhongshan gorge area, Gannan Plateau grassland and meadow area were statistically significant ( Z = - 2.770, H = 6.369, 9.936, 12.666, P < 0.05). Conclusions:The six ecological regions in Gansu Province are all iodine-deficient areas. The water iodine content varies among different ecological region types and different water supply methods. Surveys on water iodine content and the operating status of water supply facilities should be carried out regularly, and measures should be adjusted in time to prevent and control iodine deficiency disorders in accordance with local conditions.
ABSTRACT
Objective:To evaluate the effect of self-management treatment for patients with chronic Keshan disease in Gansu Province.Methods:From March to June 2018, 243 patients with chronic Keshan disease who were treated by self-management treatment outside the hospital in 7 Keshan disease counties in Gansu Province were selected as the survey subjects, and their general demographic and clinical data were collected. At the same time, the survey subjects were given a 6-month self-management treatment, and the self-management scale was used to evaluate the patients' self-management behavior before treatment and 6 months after treatment. The higher the score, the better the patients' self-management behavior. The influencing factors of self-management scale were analyzed by multiple linear regression analysis.Results:Excluding incomplete data, a total of 158 patients with chronic Keshan disease were included in this survey, including 96 males and 62 females. Compared with patients before self-management treatment, the patients' cardiac function classification and work ability improved significantly after 6 months of self-management treatment ( Z = - 4.685, - 5.934, P < 0.05); cardiothoracic ratio decreased (0.61 ± 0.08 vs 0.63 ± 0.09, t = 5.175, P < 0.05); in the cardiac color Doppler ultrasound indexes, left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were increased (0.41 ± 0.11 vs 0.36 ± 0.07, 0.21 ± 0.07 vs 0.18 ± 0.05, t = - 6.504, - 5.391, P < 0.05); the total score of the self-management scale was increased [(53.86 ± 9.29) scores vs (51.46 ± 10.50) scores, t = - 3.696, P < 0.05]. Further analysis of the efficacy of the patients' cardiac function classification showed that the patients' medication compliance was positively correlated with the efficacy of the cardiac function classification ( r = 0.243, P < 0.05). The result of multiple linear regression analysis showed that education level and efficacy of the cardiac function classification were influencing factors of the self-management scale for patients with chronic Keshan disease ( t = 2.466, 2.635, P < 0.05). Conclusion:The self-management treatment for patients with chronic Keshan disease can effectively improve heart function and improve self-management behavior.
ABSTRACT
Objective@#To evaluate microstructural damage in high myopia (HM) patients using 3T diffusion kurtosis imaging (DKI). @*Materials and Methods@#This prospective study included 30 HM patients and 33 age- and sex-matched healthy controls (HCs) with DKI. Kurtosis parameters including kurtosis fractional anisotropy (FA), mean kurtosis (MK), axial kurtosis (AK), and radial kurtosis (RK) as well as diffusion metrics including FA, mean diffusivity, axial diffusivity (AD), and radial diffusivity derived from DKI were obtained. Group differences in these metrics were compared using tract-based spatial statistics. Partial correlation analysis was used to evaluate correlations between microstructural changes and disease duration. @*Results@#Compared to HCs, HM patients showed significantly reduced AK, RK, MK, and FA and significantly increased AD, predominately in the bilateral corticospinal tract, right inferior longitudinal fasciculus, superior longitudinal fasciculus, inferior fronto-occipital fasciculus, and left thalamus (all p < 0.05, threshold-free cluster enhancement corrected). In addition, DKI-derived kurtosis parameters (AK, RK, and MK) had negative correlations (r = -0.448 to -0.376, all p < 0.05) and diffusion parameter (AD) had positive correlations (r = 0.372 to 0.409, all p < 0.05) with disease duration. @*Conclusion@#HM patients showed microstructural alterations in the brain regions responsible for motor conduction and visionrelated functions. DKI is useful for detecting white matter abnormalities in HM patients, which might be helpful for exploring and monitoring the pathogenesis of the disease.
ABSTRACT
Objective To understand the prevalence and risk factors of chronic diseases in Xilinguole League, Inner Mongolia, and its risk factors in 2017, so as to provide evidence for the prevention and treatment of chronic non-communicable diseases. Methods The stratified cluster random sampling method was used to conduct a questionnaire survey on the residents in Xianghuangqi area of Xilin Gol League, Inner Mongolia. Epidate 3.1 was used for data entry, and SPSS 25.0 was used for statistical analysis. Results The average age of the subjects was 46.2 ± 11.2 years old, and the prevalence of chronic diseases was 25.26%. The prevalence of hypertension ranks first at 18.56%; the prevalence of women is slightly higher than that of men (χ2=0.968, p2=1447.730, p2=7.790, p＜0.05); the prevalence of age increases (χ2trend=137.214, p＜0.01); the prevalence of higher education shows a downward trend (χ2trend=84.258, p＜0.01); the prevalence of BMI increases showed an upward trend (χ2trend=31.956, p＜0.01). Smoking is a risk factor for chronic diseases (OR: 1.33, 95% CI: 1.01~1.76); age is a risk factor for chronic diseases, and the prevalence is significantly higher in the age group >69 (OR: 9.11, 95% CI: 2.78~29.78); Education level is a protective factor for chronic diseases. The prevalence of college degree and above is lower than that of illiteracy (OR: 0.16, 95%CI: 0.07~0.36); residents with BMI> 28 have the highest risk of disease (OR: 2.94, 95%CI: 1.36) ~6.32). Conclusion The prevalence of chronic diseases of residents in Xianghuang Banner of Xilingol League of Inner Mongolia should not be ignored. The prevalence of chronic diseases of Mongolian residents is higher than that of Han people. Therefore, it is necessary to change their living and eating habits and improve their awareness of prevention so as to reduce the prevalence of chronic diseases.
ABSTRACT
Objective:To evaluate the quality of life of patients with chronic Keshan disease, and to explore related influencing factors, in order to provide a theoretical basis for improving the quality of life of patients with chronic Keshan disease.Methods:According to the standard of "Diagnosis of Keshan Disease" (WS/T 210-2011), 110 patients with chronic Keshan disease treated in the Jingchuan People's Hospital, Pingliang City, Gansu Province were selected as the research subjects, and demographic and disease data of the patients were collected by questionnaire survey; the quality of life of patients was assessed by the Minnesota living with heart failure questionnaire (MLHFQ); and correlation analysis was used to analyze and explore the influencing factors of patients' MLHFQ score.Results:Among the 110 patients with chronic Keshan disease, 66 were males and 44 were females, aged (60.93 ± 8.22) years; the education level was mainly junior high school or below, accounting for 92.73% (102/110); average annual family income was 20 700 yuan; the cardio-thoracic ratio of the patient was 0.64 ± 0.09; the ejection fraction (EF) was (36.71 ± 7.55)%; the labor ability classification was mainly based on simple activities, accounting for 60.91% (67/110); and the cardiac function classification was mainly Grade Ⅲ, accounting for 67.27% (74/110). The total MLHFQ scores of chronic Keshan patients were (69.17 ± 16.14) points, and the scores of physical, emotional and other fields were (26.32 ± 6.70), (15.86 ± 4.96) and (26.94 ± 6.10) points, respectively. The total MLHFQ scores had statistically significant differences among patients with different education level, cardio-thoracic ratio, EF, labor ability classification, cardiac function classification and annual family income ( F=7.121, 6.236, 4.515, 3.427, 5.418, Z=2.346 , P < 0.05). The results of correlation analysis showed that educational level and labor ability classification were negatively correlated with scores in physical field and other fields ( r=- 0.302, - 0.206, - 0.343, - 0.285, P < 0.01), and annual family income was negatively correlated with scores in emotional field ( r=- 0.263, P < 0.01). The cardiac function classification was positively correlated with scores in physical and other fields ( r=0.233, 0.210, P < 0.05). Conclusions:The quality of life of patients with chronic Keshan disease is poor. The quality of life of patients is affected by their educational level, annual family income, labor ability classification, cardiac function classification, etc.
