Objective:To investigate the status of dignity impairment in elderly incontinence-related dermatitis patients, and to systematically analyze the influencing factors in order to provide reference opinions for the formulation of medical strategies by clinical medical staff.Methods:Using the cross-sectional survey method, from April 15 to April 30, 2024, aged incontinence-related dermatitis patients were selected from 37 tertiary comprehensive hospitals in 10 provinces and municipalities, including Zhejiang Province, Sichuan Province, Guangdong Province, etc. by convenient sampling method. The general data questionnaire and Patient Dignity Inventory were used to investigate their current situation.Results:A total of 315 questionnaires were collected, 307 were valid, and the effective rate was 97.5%. Among 307 cases, 146 cases were males, 161 cases were females, aged (71.46 ± 9.35) years old. The incidence of impaired dignity in elderly patients with incontinence-related dermatitis was 49.5%(152/307). The average score of Patient Dignity Inventory was (45.50 ± 20.17). The results of multivariate regression analysis showed that farming ( OR = 2.405, 95% CI 1.108-5.217), individual industrial and commercial households ( OR = 5.680, 95% CI 2.504-12.888), the primary disease were respiratory diseases ( OR = 2.716, 95% CI 1.018-7.246) and nervous system diseases ( OR = 6.117, 95% CI 2.572-14.551) were risk factors for impaired dignity in elderly incontinence-related dermatitis (both P<0.05). Not living alone ( OR = 0.381, 95% CI 0.184-0.790) and self-rated family relationship harmony ( OR = 0.630, 95% CI 0.449-0.882) were protective factors for dignity impairment in elderly incontinence-related dermatitis patients (both P<0.05). Conclusions:There are many factors that affect the dignity of patients with incontinence-related dermatitis in the elderly, and medical staff should comprehensively consider a variety of factors and establish and improve a prevention and management mechanism suitable for the dignity of patients with incontinency-related dermatitis in the elderly.

Purpose To investigate the value of a radiomics model based on dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the differential diagnosis of granulomatous mastitis and breast cancer.Materials and Methods The MRI data of 82 patients with granulomatous mastitis or breast cancer confirmed by pathology in Xiyuan Hospital of China Academy of Chinese Medical Sciences from February 2019 to January 2022 were retrospectively collected.Based on the first phase of DCE-MRI,the regions of interest(ROI)were delineated layer by layer by semi-automatic segmentation method and manual segmentation method,respectively.99 ROI were randomly assigned to 69 in training groups and 30 in test groups.The consistency difference between the two methods was compared.The original data extracted by the semi-automatic segmentation method were screened by correlation analysis and multi-factor Logistic regression.Six kinds of classifiers(Logistic regression,support vector machine,naive Bayes,decision tree,random forest,K nearest neighbor)were used to construct prediction models,and the differences in diagnostic efficiency,accuracy,sensitivity and specificity of each model were evaluated.Results A total of 99 lesions(n=37 cases with granulomatous mastitis and n=62 cases with breast cancer)were segmented from 82 patients.The radiomics data extracted by the two ROI segmentation methods had poor consistency between groups[Intraclass correlation coefficient=0.68(0.51,0.78)].Among the six prediction models constructed from the data extracted by the semi-automatic segmentation method,the diagnostic performance of the Logistic regression model and the support vector machine model was significantly better than those of other models,and the Logistic regression model had the best diagnostic performance and stability(training group:area under the curve 0.928,accuracy rate 0.855,sensitivity 0.837,specificity 0.885;test group:area under the curve 0.933,accuracy 0.833,sensitivity 0.895,specificity 0.727,respectively).Conclusion Radiomics based on DCE-MRI can provide high value for the differential diagnosis of granulomatous mastitis and breast cancer.The semi-automatic segmentation method is more recommended for the segmentation method of ROI.The prediction model constructed by Logistic regression and support vector machine shows better diagnostic efficiency and stability.

Objective:To quantitatively analyze the plaque components of carotid artery through energy spectrum computed tomography angiography(CTA),and to measure the blood flow perfusion in the blood-supply area of carotid artery through CT perfusion(CTP),so as to explore the relationship among plaque component,the degree of luminal stenosis and cerebral blood flow perfusion.Methods:A total of 68 patients with unilateral plaques of carotid artery and severe vascular stenosis who were screened and diagnosed by ultrasound and CTA in Xiyuan Hospital from December 2017 to July 2019 were selected,and all patients underwent CTA examination and CTP examination.North American symptomatic carotid endarterectomy test(NASCET)method was used to measure the degree of carotid stenosis.The GE AW 4.7 post-process workstation was used to conduct analyses of energy spectrum and cerebral perfusion for the plaque component.And then,the slope of energy spectrum curve and the effective atomic number were obtained.At the same time,the cerebral blood volume(CBV),cerebral blood flow(CBF),time to peak(TTP)and mean transit time(MTT)of contrast agent in blood-supplying area of anterior cerebral artery(ACA)and middle cerebral artery(MCA)at the side of lesion were measured.Results:A total of 68 measured plaques of 68 patients met the condition,including 44 vulnerable plaques(including lipid plaques and mixed plaques)and 24 stable plaques(fibrous plaques).The average slopes of the energy spectrum curves of vulnerable plaque and stable plaque were respectively 0.45±0.45 and 1.15±0.39,and the differences were significant(t=2.413,P<0.05).The averagely effective atomic numbers of vulnerable plaques and stable plaques were respectively 7.21±1.06 and 8.01±0.63,and the difference were significant(t=2.548,P<0.05).The average TTP values of the ACA at the side of lesion of vulnerable plaques and stable plaques were respectively(12.20±1.61)S and(13.59±2.79)S,and the difference was significant(t=-2.607,P<0.05).The mean MTT values of the ACA at the side of lesion of vulnerable plaques and stable plaques were respectively(5.07±1.66)S and(6.09±2.19)S,and the difference was significant(t=-2.177,P<0.05).The degree of vascular stenosis at the side of lesion was positively correlated with TTP and MTT in blood-supplying area of middle cerebral artery(MCA)at the side of lesion(r=0.537,0.465,P<0.05),and that was negatively correlated with CBF values in blood-supplying areas of ACA and MCA at the side of lesion(r=-0.281,-0.569,P<0.05),respectively.The slope of the energy spectrum curve of carotid plaque was positively correlated with the TTP values in blood-supplying areas of ACA and MCA at the side of lesion(r=0.242,0.246,P<0.05),respectively.Conclusion:CT spectral imaging can quantitatively analyze the displayed components of carotid atherosclerotic plaque,and the degree of vascular stenosis can affect the blood flow perfusion of cerebral tissue,and the delays of TTP and MTT are more easily caused by vulnerable plaque,and the TTP of them is more sensitivity.

In this study, we explored the neural mechanism underlying impaired stereopsis and possible functional plasticity after strabismus surgery. We enrolled 18 stereo-deficient patients with intermittent exotropia before and after surgery, along with 18 healthy controls. Functional magnetic resonance imaging data were collected when participants viewed three-dimensional stimuli. Compared with controls, preoperative patients showed hypoactivation in higher-level dorsal (visual and parietal) areas and ventral visual areas. Pre- and postoperative activation did not significantly differ in patients overall; patients with improved stereopsis showed stronger postoperative activation than preoperative activation in the right V3A and left intraparietal sulcus. Worse stereopsis and fusional control were correlated with preoperative hypoactivation, suggesting that cortical deficits along the two streams might reflect impaired stereopsis in intermittent exotropia. The correlation between improved stereopsis and activation in the right V3A after surgery indicates that functional plasticity may underlie the improvement of stereopsis. Thus, additional postoperative strategies are needed to promote functional plasticity and enhance the recovery of stereopsis.

Hepatocellular carcinoma （HCC）， an insidious malignant tumor with high incidence and lethality， poses a major threat to physical and mental health of human beings. The pathological mechanism needs to be further studied. Surgery， radiotherapy， chemotherapy， and targeted drugs are effective but induce many adverse reactions. Traditional Chinese medicine （TCM） has unique advantages and abundant clinical experience in the treatment of HCC. There has been an explosion of research on the pathways， targets， and mechanism of TCM against HCC from the perspective of molecular biology. According to previous research， Chinese medicinals or compound Chinese medicine prescriptions， directly or indirectly prevent the occurrence and progression of HCC through multiple pathways and targets， which is closely related to the pathophysiological processes such as cell proliferation， metastasis， apoptosis， autophagy， inflammatory response， and immune response. This paper summarizes and analyzes research on the action pathways and mechanisms of Chinese medicine against HCC. Specifically， isoliquiritigenin， dendrobium candidum and Yexiazhu compound Ⅱ regulate phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway to inhibit the growth， proliferation and metastasis of tumor cells. Toad venom and dioscorea zingiberensis induce and enhance HCC autophagy by modulating mammalian target of rapamycin （mTOR） signaling pathway. Myricetin， asparagus， and Biejiajian Wan regulate mitogen-activated protein kinase （MAPK） signaling pathway to promote HCC cell cycle arrest， inhibit angiogenesis， and induce apoptosis. Polygonum odoratum， tetragonum， and plantainoside modulate nuclear factor-kappa B （NF-κB） to inhibit inflammatory response and HCC metastasis and reduce drug resistance. Quercetin and erigeron breviscapus control the Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） signaling pathway to suppress epithelial-mesenchymal transition （EMT） and remodel cytoskeleton. This paper is expected to lay a theoretical basis for the in-depth research on and clinical application of Chinese medicine in the treatment of HCC.

Objective: To evaluate the value of Kirschner wire internal fixation in the treatment of sagittal mandibular condylar fractures. .Methods : From January 2019 to January 2020, 13 patients (19 sides) with mandibular condylar sagittal fracture treated by Kirschner wire internal fixation at the Stomatological Medical Center, Foshan Hospital of Traditional Chinese Medicine were retrospectively analyzed. After conventional surgical incision and exposure and reduction of the mandibular condyle, 2-4 Kirschner wires were used for fixation, and other maxillofacial fractures were treated simultaneously. The reduction accuracy and stability of the free mandibular condyle were evaluated by CBCT one week after the operation, and the occlusion relationship, opening degree and opening type were evaluated by clinical examination. Results: All patients had good fracture alignment and no twisting, breaking or loosening of the Kirschner wire. The occlusion relationship, opening degree and opening shape recovered well after the operation. Conclusion Kirschner wire is effective in treating sagittal fractures of mandibular condyles.

Objective:To analyze the molecular epidemiological characteristics of GⅡNorovirus (NoV) infection in children in Tianjin Children′s Hospital in 2018.Methods:Single center study. From January to December 2018, a total of 2 185 stool specimens were collected from the children with acute gastroenteritis suspected caused by virus infection in Tianjin Children′s Hospital. Norovirus was detected by real-time fluorescence reverse transcription polymerase chain reaction (RT-PCR).The capsid protein VP1(VP1) region of positive samples was amplified and sequenced. The phylogenetic tree was constructed by MEGA5.05 for analyzing the results. The detection of NoV in different age groups and different months were compared by SPSS 20.0.Results:Among the 2 185 stool specimens,610 were NoV positive, the positive rate was 27.9% (610/2 185).All of the positive samples were GⅡgenogroup. Seven genotypes were found, with GⅡ.3 subtype accounting for 46.2%(151/327),GⅡ.4 subtype accounting for 40.1%(131/327),GⅡ.2 subtype accounting for 4.6%(15/327), other subtypes accounting for 9.1%(30/327).There was a significant difference in NoV detection rate among different age groups (χ 2=17.050, P=0.002). Among the positive specimens, the detection rate of less than or equal to 3 years old was the highest which is accounting for 89.2%.Also there was a significant difference in NoV detection rate among different months(χ 2=225.153, P<0.001).November and December are the most frequent months. There was significant difference between GⅡ.3 and GⅡ.4 NoV infection in children with granulocytopenia (χ 2=11.270, P=0.001) , and also in children with respiratory symptoms (χ 2=7.257, P=0.007) . Conclusions:GⅡ.3 and GⅡ.4 were the main genotypes of NoV infection in children in Tianjin in 2018. The Multiple genotypes suggests that the monitoring and prevention of NoV infection in children should continue to be strengthened in the future.

Objective : To explore the effect of negative pressure sealing drainage on the treatment of maxillofacial-neck-mediastinal infection in multiple spaces. Methods: Vacuum sealing drainage (VSD) was applied in five patients with maxillofacial-neck-mediastinal infection caused by odontogenic infection accompanied by diabetes or renal failure and other systemic diseases. After extensive debridement, a negative pressure drainage sponge was placed in the pus cavity and then the wound was closed. Continuous negative pressure drainage was continued after the operation. At the same time, multidisciplinary consultation was applied to control basic diseases and, strengthen anti-inflammatory responses, and nutrition and other systemic treatments were applied. Results: Four patients underwent continuous negative pressure drainage and successful removal of the negative pressure sponge after inflammatory symptoms subsided. One patient′s inflammatory symptoms became more serious after the operation, and we performed another operation to change the placement of the negative pressure sponge. All 5 patients underwent VSD with negative pressure sponge replacement ranging from 1 to 3 times during treatment. After multidisciplinary consultation, they were all cured and discharged from the hospital. Conclusion For infection of the mediastinum, maxillofacial region and neck, local treatment and systemic treatment are emphasized, as well as the treatment of infected lesions and basic diseases. Negative pressure closure and drainage technology promotes the alleviation of inflammation, and multidisciplinary combined treatment is beneficial for the control of basic diseases.
