ABSTRACT

Spinal cord infarction is a rare type of central nervous system ischemic disease. Previous studies have mainly been based on a small number of clinical case reports and retrospective analyses. Its causes are diverse, mainly including vasogenic, systemic and iatrogenic diseases. Spinal cord infarction is mostly acute onset, and its clinical manifestation depends on the infarct location and infarct size, and is usually diagnosed based on combined MRI and other examinations. At present, there is no unified treatment plan for spinal cord infarction, and the mortality and disability are relatively higher. This article reviews the clinical characteristics of spinal cord infarction, and provides help for clinical decision making.

ABSTRACT

Objectives@#To establish a geographic information application system for analyzing the spatial and temporal distribution of major infectious diseases in various regions of the world and to assess the risk of importation of those diseases, to China.@*Methods@#We collected and integrated the following information on: 1) outbreaks and areas of epidemics of major infectious diseases in the world from 2000 to 2017, 2) cases of infectious diseases in arriving travelers through active surveillance at international entry-exit ports in mainland China from 2014 to 2016, 3) numbers of annual global international flights and travelers in the country. With the above information, a global space-time distribution database on major infectious diseases was then established, using the technology related to the system. Models regarding technologies on time-space analysis, probabilistic risk assessment and geographic information visualization, were applied to establish a geographic information system on risk assessment of infectious diseases that imported to China.@*Results@#Through integration of information on outbreaks and epidemic areas of 60 major infectious diseases in 220 countries and regions around the world, as well as 42 kinds of infectious diseases identified among the international arrivals in mainland China, a system was then developed. Information on the distribution of major infectious diseases and their potential risks in the worldwide various regions, characteristics of spectrum and disease burden of infectious diseases imported to each province of mainland China were displayed. Thus, risks on importing infectious diseases in each province via air way were able to be evaluated and simulated by the probabilistic risk assessment model, under the information on specific kind of infectious disease, outside China.@*Conclusion@#Geographic Information System on Risk Assessment Regarding Infectious Diseases Imported to China provides basic data for epidemiological reconnaissance and assessment on risks of importing infectious diseases outside China, thus would be helpful for the improvement of strategies on surveillance, prevention and control regarding the importing infectious diseases, in China.

ABSTRACT

AIM: To analyze the value of 24 - hour intraocular pressure ( IOP) monitoring in suspected glaucoma patients. METHODS: Totally 48 suspected glaucoma (96 eyes) were selected for 24 - hour IOP monitoring by using Accupen tonometer (24 - 3000) and non - contact tonometer (NCT, CT-80A) from 9 30 to 7 30 next day (once in 2h). During 07 30 to 21 30, patients were measured in sitting position,while during 23 30 to 05 30 in both sitting and supine position. RESULTS:A morning peak of IOP was shown at 7 30 in traditional position by using two measures with 22.05士3 608mmHg of NCT and 19.79士4.147mmHg of Accupen tonometer. The peak IOP in habitual position appeared in 5 30 with 21.64士4.814mmHg. The lowest IOP occurred in both position at 21 30 with 15. 73士3. 649mmHg. Both positions showed IOP trend of going up at night and then declining in the morning. CONCLUSION: The peak IOP in suspected glaucoma occurs mostly at early morning. Supine IOP of sleeping time is higher than that of sitting position.

ABSTRACT

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a debilitating lung disease. To date, a large number of clinical studies have been conducted to investigate the association between genetic variations and COPD. However, little is known regarding the genetic susceptibility of Koreans to this disease. MER receptor tyrosine kinase (MERTK) plays important roles in the inhibition of inflammation and in the clearance of apoptotic cells. Here, we investigated the association between genetic variations in MERTK and the development of COPD in Koreans. METHODS: We conducted genetic analysis of MERTK using genomic DNA samples from 87 patients with COPD and 88 healthy controls and compared the frequency of each variation or haplotype between the patient and control groups. Subsequently, the effect of each variation was evaluated using in vitro assays. RESULTS: Ten variations were identified in this study, four of them for the first time. In addition, we found that the frequency of each variation or haplotype was comparable between the patient and control groups. However, we observed that the frequency for the wild-type haplotype was higher in the control group, compared to that in the group of patients with COPD, in the subgroup analysis of current smokers, although the difference was not statistically significant (P = 0.080). In in vitro assays, we observed that none of the variations affected the activity of the promoter or the expression of MERTK. CONCLUSION: Our findings indicate that the susceptibility to COPD is not related to the genetic variations or haplotypes of MERTK in Koreans.

ABSTRACT

ABSTRACT Objective To evaluate the clinical utility of 18F-FDG PET/CT in patients with high-risk DTC. Subjects and methods Single-center retrospective study with 74 patients with high-risk differentiated thyroid cancer (DTC), classified in 4 groups. Group 1: patients with positive sTg or TgAb, subdivided in Group 1A: negative RxWBS and no foci of metastases identified at conventional image (n = 9); Group 1B: RxWBS not compatible with suspicious foci at conventional image or not proportional to sTg level (n = 13); Group 2: patients with histological findings of aggressive DTC variants (n = 21) and Group 3: patients with positive RxWBS (n = 31). Results 18F-FDG PET/CT identified undifferentiated lesions and helped restage the disease in groups 1B and 2. The scan helped guide clinical judgment in 9/13 (69%) patients of group 1B, 10/21 (48%) patients of group 2 and 2/31 (6%) patients of group 3. There was no clinical benefit associated with group 1A. 18F-FDG PET/CT was associated with progressive disease. Conclusion 18F-FDG PET/CT is a useful tool in the follow-up of patients with high-risk DTC, mainly in the group of RxWBS not compatible with suspicious foci at conventional image or not proportional to sTg level and in those with aggressive DTC variants. Additionally, this study showed that 18F-FDG PET/CT was associated with progression and helped display undifferentiated lesions guiding clinical assessments regarding surgeries or expectant treatments.

ABSTRACT

BACKGROUND: There are many studies on the effect of different experimental parameters on the tetragonal phase of zirconia, but it is unclear whether pH values have effects on the tetragonal phase in hydrothermal reactionOBJECTIVE: To prepare two zirconia systems via hydrothermal method and to regulate the tetragonal phase purity and control the grain size of zirconia (ZrO2) crystal by pH values.METHODS: Analytical reagents Zr(NO3)4?5H2O and Y(NO3)3?6H2O were adopted as reactors, and nano-sized neat ZrO2 and yttria-stabilized tetragonal ZrO2 polycrystal (Y-TZP) powders were synthesized using the hydrothermal method. X-ray diffraction was adopted to characterize the influence of pH values and pH regulators (NaOH solution and ammonium hydroxide/NaOH solution) on phase purity and grain size of tetragonal zirconia.RESULTS AND CONCLUSION: Pure zirconia samples with a grain size lower than 20 nm were obtained through the hydrothermal method, and samples with higher tetragonal phase content compared to monoclinic phase could be derived when the pH value was higher than 10. The optimal pH values for neat zirconia and Y-TZP were 13 and 12,respectively. Furthermore, the ammonium hydroxide/NaOH solution was more favorable to enhance the content of tetragonal zircona. Therefore, the control of pH values and rational choice of pH regulators can improve the tetragonal phase purity and grain size of zirconia.

ABSTRACT

Computational three-dimensional (3D) models of a dental structure generated from 3D dental computed tomography (CT) images are now widely used in digital dentistry. To generate precise 3D models, high-resolution imaging of the dental structure with a dental CT is required. However, a small head motion of the patient during the dental CT scan could degrade the spatial resolution of CT images to the extent that digital dentistry is no longer possible. A bench-top micro-CT has been built to evaluate the head motion effects on the dental CT images. A micro-CT has been built on an optic table with a micro-focus x-ray source and a flat-panel detector. A rotation stage, placed in between the x-ray source and the detector, is mounted on two-directional goniometers that can rotate the rotation stage in two orthogonal directions while the rotation stage is performing the CT scan. The goniometers can make object motions of an arbitrary waveform to simulate head tilting or head nodding. CT images of a phantom have been taken with and without introducing the motions, and the motion effects on the CT images have been evaluated. Object motions parallel to the detector plane have greater effects on the CT images than those against the detector plane. With the bench-top micro-CT, the motion effects have been visually seen at a tiny rotational motion as small as 0.3°. The bench-top micro-CT can be used to evaluate head motion effects on the dental CT images. The projection data, taken with the motion effects, would be used to develop motion artifact correction methods for a high-resolution dental-CT.

ABSTRACT

PURPOSE: This study was conducted to identify and to functionally characterize genetic variants in ST3GAL5 and ST8SIA1 in Korean patients with thyroid-associated ophthalmopathy (TAO). MATERIALS AND METHODS: Genetic analyses were conducted using DNA samples from TAO patients (n=50) and healthy subjects (n=48) to identify TAO-specific genetic variants of ST3GAL5 or ST8SIA1. The effect of each genetic variant on the transcription or expression of these genes was examined. Additionally, correlations between functional haplotypes of ST3GAL5 or ST8SIA1 and clinical characteristics of the patients were investigated. RESULTS: Six promoter variants and one nonsynonymous variant of ST3GAL5 were identified, and four major promoter haplotypes were assembled. Additionally, three promoter variants and two major haplotypes of ST8SIA1 were identified. All ST3GAL5 and ST8SIA1 variants identified in TAO patients were also found in healthy controls. Promoter activity was significantly decreased in three promoter haplotypes of ST3GAL5 and increased in one promoter haplotype of ST8SIA1. Transcription factors activating protein-1, NKX3.1, and specificity protein 1 were revealed as having roles in transcriptional regulation of these haplotypes. The nonsynonymous variant of ST3GAL5, H104R, did not alter the expression of ST3GAL5. While no differences in clinical characteristics were detected in patients possessing the functional promoter haplotypes of ST3GAL5, exophthalmic values were significantly lower in patients with the ST8SIA1 haplotype, which showed a significant increase in promoter activity. CONCLUSION: These results from genotype-phenotype analysis might suggest a possible link between the ST8SIA1 functional promoter haplotype and the clinical severity of TAO. However, further studies with larger sample sizes are warranted.

ABSTRACT

<p><b>BACKGROUND</b>Antegrade selective cerebral perfusion (ASCP) is regarded to perform cerebral protection during the thoracic aorta surgery as an adjunctive technique to deep hypothermic circulatory arrest (DHCA). However, brain metabolism profile after ASCP has not been systematically investigated by metabolomics technology.</p><p><b>METHODS</b>To clarify the metabolomics profiling of ASCP, 12 New Zealand white rabbits were randomly assigned into 60 min DHCA with (DHCA+ASCP [DA] group, n = 6) and without ( DHCA [D] group, n = 6) ASCP according to the random number table. ASCP was conducted by cannulation on the right subclavian artery and cross-clamping of the innominate artery. Rabbits were sacrificed 60 min after weaning off cardiopulmonary bypass. The metabolic features of the cerebral cortex were analyzed by a nontargeted metabolic profiling strategy based on gas chromatography-mass spectrometry. Variable importance projection values exceeding 1.0 were selected as potentially changed metabolites, and then Student's t-test was applied to test for statistical significance between the two groups.</p><p><b>RESULTS</b>Metabolic profiling of brain was distinctive significantly between the two groups (Q 2 Y = 0.88 for partial least squares-DA model). In comparing to group D, 62 definable metabolites were varied significantly after ASCP, which were mainly related to amino acid metabolism, carbohydrate metabolism, and lipid metabolism. Kyoto Encyclopedia of Genes and Genomes analysis revealed that metabolic pathways after DHCA with ASCP were mainly involved in the activated glycolytic pathway, subdued anaerobic metabolism, and oxidative stress. In addition, L-kynurenine (P = 0.0019), 5-methoxyindole-3-acetic acid (P = 0.0499), and 5-hydroxyindole-3-acetic acid (P = 0.0495) in tryptophan metabolism pathways were decreased, and citrulline (P = 0.0158) in urea cycle was increased in group DA comparing to group D.</p><p><b>CONCLUSIONS</b>The present study applied metabolomics analysis to identify the cerebral metabolic profiling in rabbits with ASCP, and the results may shed new lights that cerebral metabolism is better preserved by ASCP compared with DHCA alone.</p>

ABSTRACT

Objective To evaluate the prognostic value of the log odds of positive lymph nodes (LODDS) in stage 3 colorectal cancer (CRC) patients who have undergone curative resection. Methods We performed a retrospective review of 175 stage 3 CRC patients who underwent curative resection in Peking Union Medical College Hospital from 2005 to 2012. Patients were categorized respectively according to the AJCC/UICC N grade,the metastatic lymph node ratio (LNR),and the ratio of their LODDS. The relationship between the N grade,LNR,LODDS,and overall survival (OS) rates were assessed.Results The five-year disease-free survival (DFS) was significantly different among stage 3 CRC patients in different N grade (Χ(2)=33.1,P=0.000),LNR (Χ(2)=14.3,P=0.001),and LODDS (Χ(2)=14.9,P=0.001). Univariate analysis showed that TNM stage (Χ(2)=27.0,P=0.000),cancerous node(Χ(2)=3.6,P=0.040),N grade (Χ(2)=33.1,P=0.000),LNR (Χ(2)=14.3,P=0.001),and LODDS (Χ(2)=30.4,P=0.000) were related to OS. Multivariate analysis indicated that TNM stage (HR:1.84,95%CI:1.59~6.29,P=0.001) and LODDS classification (HR:1.34,95%CI:1.01~1.80,P=0.047) were independent prognostic factors for OS in stage 3 CRC patients. Conclusion LODDS is a good prognostic indicator in stage 3 CRC patients who have undergone curative resection.

ABSTRACT

OBJECTIVE: Salvia miltiorrhiza has long been used to treat systemic sclerosis. Tanshinone IIA, one of the phytochemicals derived from the roots of Salvia miltiorrhiza, exhibits multiple biological activities. The present study aimed to investigate whether tanshinone IIA has an effect on the interleukin-17A-induced functional activation of systemic sclerosis patient-derived dermal vascular smooth muscle cells. METHODS: Systemic sclerosis patient-derived dermal vascular smooth muscle cells were incubated with various dosages of tanshinone IIA in the presence of interleukin-17A or the serum of systemic sclerosis patients. Cell proliferation was assessed using Cell Counting Kit-8. The expression of collagen 1 and 3 in cells was evaluated by immunofluorescence. Cell migration was measured using a transwell assay. The expression of phospho-extracellular signal-regulated kinase was detected by Western blotting. RESULTS: Our data demonstrate that tanshinone IIA exerts an inhibitory effect on interleukin-17A-induced systemic sclerosis patient-derived dermal vascular smooth muscle cell proliferation, collagen synthesis and migration. CONCLUSION: These findings suggest that tanshinone IIA might serve as a promising therapeutic agent for the treatment of systemic sclerosis. .

ABSTRACT

BACKGROUND:Dendritic cel s can regulate the immunological reaction in the intestinal tract, this functional deficit may induce inflammatory bowel disease. Tol-like receptor-4/nuclear factor-κB pathway is highly involved in this reaction. OBJECTIVE:To establish experimental colitis model in rats, to observe effects of resina draconis on dendritic cel s and Tol-like receptor-4/nuclear factor-κB expression in rats with experimental colitis, and to explore its action mechanism. METHODS:A total of 44 male Sprague-Dawley rats were randomly assigned to four groups (n=11):blank control group, model group, resina draconis group, 5-aminosalicylic acid treatment group. With the exception of blank control group, 2,4,6-trinitrobenzenesulfonic acid-induced ulcerative colitis models were established in the model group, resina draconis group and 5-aminosalicylic acid treatment group. After the models were successful y established, the rats in the resina draconis and 5-aminosalicylic acid treatment groups were intragastrical y treated with resina draconis [(0.75 g(kg·d)] and 5-aminosalicylic acid [100 mg(kg·d)] respectively for 10 days. RESULTS AND CONCLUSION:Disease activity index, macroscopic colonic damage score and histopathological score were significantly decreased in the resina draconis group compared with the model group (P<0.05). Symptoms and tissue damages were obviously lessened in the 5-aminosalicylic acid treatment and resina draconis groups compared with the model group. Expression rates of CD80 and CD86, as wel as expression levels of Tol-like receptor-4 and nuclear factor-κB were significantly higher in the model group compared with the blank control group, resina draconis group and 5-aminosalicylic acid treatment group (P<0.05, P<0.01). Tol-like receptor-4 and nuclear factor-κB expression was significantly lower in the resina draconis group than that in the 5-aminosalicylic acid treatment group. Experimental findings indicate that, resina draconis can partial y relieve experimental colitis symptoms in rats and effectively inhibit the activation of dendritic cel s in the mesenteric lymph node. Resina draconis can relieve enteric inflammatory reaction by suppressing the expression of Tol-like receptor-4 and nuclear factor-κB in rats.
