RESUMEN
[Objective]Using CiteSpace software to visualize and analyse the literature related to acupuncture treatment of post-stroke dysphagia in China,to reveal the dynamics of frontiers and the evolution of hotspots in this field,as well as provide suggestions and references for future research.[Methods]By searching the three major Chinese databases,China National Knowledge Internet(CNKI),Wanfang Data and China Science and Technology Journal Database(VIP),the literature related to acupuncture treatment of post-stroke dysphagia was retrieved between the establishment of these databases and June 2023.Then the data issuance,authors,institutions,keywords clustering and keywords emergence were analyzed and presented in a visualization map or chart with CiteSpace 6.1.R6 software.[Results]After searching and screening,a total of 1 585 relevant literatures were included,and the overall trend of the number of studies within the field showed a steady increase in terms of the number of publications.However,links among study authors are scattered and mostly intra-institutional.At the same time,the connection among institutions for cross-regional collaboration is not close enough.Keywords clustering analysis showed that the type of research in the literature mainly consists overviews and clinical randomized controlled trial(RCT).In terms of treatment approaches,the use of combination of multiple therapies is common.The time zone map reflects the continuous process of refinement of acupuncture therapies,from which the creation of a series of new types of acupuncture therapies could be observed.[Conclusion]The field of acupuncture for the treatment of post-stroke dysphagia is becoming increasingly sophisticated.It is predicted that the combination of acupuncture with other common therapies for the treatment of post-stroke dysphagia will remain a hot research topic in the coming years.Meanwhile,there will be a new trend towards integrating resources and conducting high-quality clinical studies with multi-centre collaboration.
RESUMEN
【Objective】 To compare the diagnostic performance of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB) enhanced magnetic resonance imaging (MRI) and multi-detector computed tomography (MDCT) in detecting liver metastases from metastatic colorectal cancer (mCRC). 【Methods】 We made a retrospective collection of 128 patients diagnosed with mCRC from May 2019 to June 2022 at Haikou Hospital, Xiangya School of Medicine, Central South University and Xijing Hospital, Air Force Military Medical University. All patients underwent Gd-EOB MRI and MDCT imaging. Three radiologists judged the accuracy, sensitivity, specificity, positive predictive value and negative predictive value of the two modalities for colorectal liver metastases, respectively. 【Results】 Of the 128 patients diagnosed with mCRC, a total of 462 lesions were obtained, with 424 positive and 38 negative metastases confirmed by pathology. In the interpretation of physician A, Gd-EOB MRI judged 404 positive and 38 negative liver metastases, with accuracy of 95.67%, sensitivity of 95.28%, specificity of 100.00%, a positive predictive value of 100%, and a negative predictive value of 65.52%. MDCT judged 337 positive and 37 negative liver metastases, with accuracy of 80.95%, sensitivity of 79.48% and specificity of 97.37%, a positive predictive value of 99.70%, and a negative predictive value of 29.84%. In the interpretation of physician B, Gd-EOB MRI judged 403 positive and 36 negative liver metastases, with accuracy of 95.02%, sensitivity of 95.05%, specificity of 94.74%, a positive predictive value of 99.51%, and a negative predictive value of 64.91%. MDCT judged 335 positive and 35 negative liver metastases, with accuracy of 80.09%, sensitivity of 79.01%, specificity of 92.11%, a positive predictive value of 99.11%, and a negative predictive value of 28.23%. In the interpretation of physician C, Gd-EOB MRI judged 406 positive and 38 negative liver metastases, with accuracy of 96.10%, sensitivity of 95.75%, specificity of 100.00%, a positive predictive value of 100.00%, and a negative predictive value of 67.86%. MDCT judged 352 positive and 34 negative liver metastases, with accuracy of 83.55%, sensitivity of 83.02%, specificity of 89.47%, a positive predictive value of 98.88%, and a negative predictive value of 32.08%. Gd-EOB MRI judged the nature of liver metastases with higher accuracy, sensitivity and negative predictive value than MDCT, and had better agreement with pathological examination results in the judgment of physician A and physician C (Kappa=0.770, 0.788). In physician B’s judgment, the agreement with pathological findings was fair (Kappa=0.731), while the agreement between the results of MDCT examination and pathological findings was poor (Kappa=0.379, 0.378 and 0.400). 【Conclusion】 Gd-EOB MRI has higher accuracy, sensitivity and positive predictive rate than MDCT in diagnosing colorectal liver metastasis, and has higher diagnostic performance. Therefore, it can provide more valuable reference information for clinical differential diagnosis. Subcapsular lesions, peribiliary metastases and hepatic steatosis can reduce the diagnostic performance of MDCT, while Gd-EOB MRI detection can provide more accurate results than MDCT.
RESUMEN
Objective:To investigate and summarize the chest CT imaging features of patients with novel coronavirus pneumonia (COVID-19), bacterial pneumonia and other viral pneumonia.Methods:Chest CT data of 102 patients with pulmonary infection due to different etiologies were retrospectively analyzed, including 36 patients with COVID-19 admitted to Hainan Provincial People's Hospital and the Second Affiliated Hospital of Hainan Medical University from December 2019 to March 2020, 16 patients with other viral pneumonia admitted to Hainan Provincial People's Hospital from January 2018 to February 2020, and 50 patients with bacterial pneumonia admitted to Haikou Affiliated Hospital of Central South University Xiangya School of Medicine from April 2018 to May 2020. Two senior radiologists and two senior intensive care physicians were participated to evaluated the extent of lesions involvement and imaging features of the first chest CT after the onset of the disease.Results:Bilateral pulmonary lesions were more common in patients with COVID-19 and other viral pneumonia, and the incidence was significantly higher than that of bacterial pneumonia (91.6%, 75.0% vs. 26.0%, P < 0.05). Compared with other viral pneumonia and COVID-19, bacterial pneumonia was mainly characterized by single-lung and multi-lobed lesion (62.0% vs. 18.8%, 5.6%, P < 0.05), accompanied by pleural effusion and lymph node enlargement. The proportion of ground-glass opacity in the lung tissues of patients with COVID-19 was 97.2%, that of patients with other viral pneumonia was 56.2%, and that of patients with bacterial pneumonia was only 2.0% ( P < 0.05). The incidence rate of lung tissue consolidation (25.0%, 12.5%), air bronchial sign (13.9%, 6.2%) and pleural effusion (16.7%, 37.5%) in patients with COVID-19 and other viral pneumonia were significantly lower than those in patients with bacterial pneumonia (62.0%, 32.0%, 60.0%, all P < 0.05), paving stone sign (22.2%, 37.5%), fine mesh sign (38.9%, 31.2%), halo sign(11.1%, 25.0%), ground-glass opacity with interlobular septal thickening (30.6%, 37.5%), bilateral patchy pattern/rope shadow (80.6%, 50.0%) etc. were significantly higher than those of bacterial pneumonia (2.0%, 4.0%, 2.0%, 0%, 22.0%, all P < 0.05). The incidence of local patchy shadow in patients with COVID-19 was only 8.3%, significantly lower than that in patients with other viral pneumonia and bacterial pneumonia (8.3% vs. 68.8%, 50.0%, P < 0.05). There was no significant difference in the incidence of peripheral vascular shadow thickening in patients with COVID-19, other viral pneumonia and bacterial pneumonia (27.8%, 12.5%, 30.0%, P > 0.05). Conclusions:The probability of ground-glass opacity, paving stone and grid shadow in chest CT of patients with COVID-19 was significantly higher than those of bacterial pneumonia, and it was more common in the lower lungs and lateral dorsal segment. In other patients with viral pneumonia, ground-glass opacity was distributed in both upper and lower lungs. Bacterial pneumonia is usually characterized by single lung consolidation, distributed in lobules or large lobes and accompanied by pleural effusion.
RESUMEN
Objective:To explore the relationship between different admission sources and outcomes at children in pediatric intensive care unit(PICU).Methods:The clinical data of children admitted to PICU of Henan Provincial People′s Hospital from January 1, 2021 to December 31, 2021 were collected.The children were divided into emergency group, outpatient group, ward transfer group and out-hospital transfer group according to different admission sources, and the influence of different admission sources on the outcome of children was analyzed.Results:A total of 413 children were included in the study.There were 141 cases(34.14%)in emergency group, 14 cases(3.39%)in outpatient group, 115 cases(27.85%)in ward transfer group and 143 cases(34.62%)in out-hospital transfer group.There were significant differences among the four groups in terms of age, length of hospital stay, PCIS score, type of disease, duration of mechanical ventilation and outcome of children( P<0.05). There was no significant difference in gender among the four groups( P=0.328). Among the 143 children of out-hospital transfer group, 92 cases(64.3%)were admitted during the day and 51 cases(35.7%)were admitted in the night.There was no significant difference in age, gender, duration of mechanical ventilation, PCIS score, length of hospital stay and outcome of children between two groups( P>0.05). The independent risk factors for mortality of children in out-hospital transfer group were length of hospital stay( OR=0.717, 95% CI 0.582-0.883, P=0.002), gender( OR=13.185, 95% CI 2.044-85.061, P=0.007), duration of mechanical ventilation>1 day( OR=23.524, 95% CI 3.294-168.026, P=0.002)and PCIS score≤80( OR=6.000, 95% CI 1.637-21.985, P=0.007). Conclusion:PICU children in our hospital mainly come from emergency, ward transfer and out-hospital transfer.The patients transferred from other hospitals were the most critically ill and had the worst outcome, suggesting that we need to develop and popularize referral standards for critically ill children and establish a transport system so that children can receive timely referral and effective treatment, so as to reduce the risk of death of referred children as far as possible.
RESUMEN
Objective:To explore the application value of apparent diffusion coefficient (ADC) of magnetic resonance diffusion weighted imaging (DWI) parameters in glioma classification and glioma microstructure evaluation.Methods:From June 2017 to November 2019, 38 patients with glioma confirmed by surgery and pathology in Haikou Hospital Affiliated to Xiangya Medical College of Central South University were retrospectively analyzed. According to the pathological results, they were divided into low-grade (WHO Ⅰ-Ⅱ, 15 cases) glioma group and high-grade (WHO Ⅲ-Ⅳ, 23 cases) glioma group. They received magnetic resonance imaging (MRI) plain scan and DWI scan respectively, and the ADC value and microstructure of different grades of glioma were compared. The correlation between ADC value of glioma and the percentage of vascular endothelial growth factor (VEGF)-positive cells, cell density and integrated optical density (IOD) value of aquaporin 1 (AQP1) expression was analyzed.Results:(1) MRI examination showed that the signals of low-grade glioma were more uniform, with no or slight peritumoral edema and space occupying effect, and the enhancement was more non enhanced or slightly enhanced. The signals of high-grade glioma were more heterogeneous due to necrosis and bleeding, and the peritumoral edema and space occupying effect were more obvious, showing uneven obvious enhancement or irregular ring enhancement; (2) The percentage of VEGF positive cells, cell density and the IOD value of AQP1 expression in high-grade glioma were significantly higher than that in low-grade glioma, and the ADC value was lower than that in low-grade glioma (all P<0.05); (3) The ADC value of glioma patients was negatively correlated with the percentage of VEGF-positive cells, cell density, and the IOD value of AQP1 expression ( r=-0.55, -0.65, -0.63, all P<0.05). Conclusions:The ADC value of glioma can indirectly reflect the expression of VEGF, cell density and AQP1 positive expression level, which is helpful for preoperative glioma classification and evaluation of glioma microstructure and biological characteristics.

RESUMEN
Objective To investigate the value of multi-b value DWI combined with PSA evaluation on the effect of endocrinotherapy for prostate cancer (PCa), and to study the correlation between the signal intensity(SI), apparent diffusion coefficient(ADC) with PSA.Methods Forty patients with PCa diagnosed by pathology or biopsy were tested for serum PSA levels before and after endocrine therapy.All patients underwent DWI at b-value of 300,800 and 1 000 s/mm2 by using a GE Signa HDx 3.0T MRI scanner.The serum PSA,the value of SI and ADC at different b values before and after endocrine therapy,and their correlation with PSA were observed and measured, respectively.Results (1)The serum PSA before and after endocrine therapy were (35.63±20.91) ng/mL and (5.98±3.84) ng/mL, respectively.The difference was statistically significant (P0.05).(3)Pearsoncorrelation analysis showed that ADC value was negatively correlated with serum PSA (r300=-0.58,P<0.01;r800=-0.60,P<0.01;r1 000=-0.66,P<0.01) before endocrine therapy.ADC value was also negatively correlated with serum PSA (r300=-0.55,P<0.01;r800=-0.52,P<0.01;r1 000=-0.61,P<0.01) after endocrine therapy.In addition,SI was negatively correlated with serum PSA (r300=-0.09,P<0.01;r800=-0.18,P<0.01;r1 000=-0.28,P<0.01) before the treatment, as well.Conclusion ADC value at different b values increased after endocrine therapy in Pca, and is negatively correlated with serum PSA.The correlation is the most significant at b value of 1 000 s/mm2.The combination of DWI and serum PSA could be used to monitor and evaluate the effect of endocrinotherapy for Pca, and better guide the clinical treatment of Pca.
RESUMEN
Objective To investigate the usefulness of different-b-value diffusion weighted imaging (DWI) in patients with early cerebral infarction and obtain the optimal b value of early cerebral infarction.Methods DWI at b-value of 1,000,2,000,and 3,000 s/mm2 was performed for 40 patients within 72 h after the onset of stroke using a GE Signa HDx 3.0T MRI scanner.Post-processing was done by the DWI specific software Function Tool to gain signal intensity and mean apparent diffusion coefficient in the lesions center and the contralateral normal brain tissue,respectively.The sensitivity of conventional MRI and different-b-value DWI was calculated in the diagnosis of early cerebral infarction.Results In 40 patients with early cerebral infarction,the sensitivity of b-values of 1,000,2,000,and 3,000 s/mm2 (DWIb=1 000,DWIb=2 000,DWIb=3 000) and conventional MRI in the diagnosis of early cerebral infarction were 100%,97.5%,97.5%,72.5%,respectively.With b value increased,signal intensity and ADC value declined.Under the condition of different b values,signal intensity and ADC value were statistically significant in region of interest (P<0.05).Conclusion DWI is superior to conventional MRI scan in monitoring early cerebral infarction.With the increase of b value,the sensitivity is the higher to hyperacute cerebral infarction,the signal contrast is obvious,while signal to noise ratio of the image reduces.It is suggested that brain tissue contrast and the sensitivity to the new cerebral infarction is more predictable on b value =1,000 DWI than on the other DWIs.
