Post-stroke cognitive impairment (PSCI) which has been a barrier to the rehabilitation, could be prevented and treated. Early assessment of cognitive impairment, as well as diagnosis and comprehensive interventions of PSCI would improve rehabilitation of stroke patients. The rehabilitation, as an important component of the comprehensive intervention, could improve cognitive function, delay disease progression, and optimize the daily life. The widely-used rehabilitation methods include cognitive intervention, exercise training, music therapy, and neuromodulation techniques, etc. Comprehensive cognitive training covering multiple cognitive domains and multimodal intervention can significantly improve the overall cognitive function of patients. The research in the PSCI field is still in its infancy in China. Thus, It is necessary to pay more attention to the PSCI clinically, and unveil the unkown area in PSCI.
Objective To summarize the research progress of intraductal papillary mucinous neoplasms (IPMNs). Method The domestic and international published literatures related to IPMNs in recent years were collected and reviewed． Results Based on the site of tumor involved, IPMNs were classified into main duct, branch duct, and mixed types. According to the histologic features, IPMNs were divided into intestinal, pancreatobiliary, gastric, and oncocytic types. The pathological and clinical presentations of IPMNs were vary, and multiple imaging approaches including endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasonography (EUS), CT, magnetic resonance cholangiopancreatography (MRCP) combined with MRI, could display morphologic and functional characteristics of IPMNs. In additon, the risk of malignancy in IPMNs could be evaluated and the functions of some genes (including KRAS, BRAF, GNAS, and so on) in the development process of IPMNs had been confirmed. Conclusion IPMNs is a kind of disease different from other tumors of the pancreas in clinicopathologic features, imaging performance, and molecular biology changes, and how to link the above three aspects needs to be further studied.
ObjectiveTo investigate the relationship between preoperative C-reactive protein (CRP)/albumin ratio (CAR) and National Institutes of Health (NIH) risk classification in patients with gastric stromal tumors.MethodsClinical data of 108 patients with gastric stromal tumors admitted to the First Affiliated Hospital of Kunming Medical University from February 2010 to November 2016 were retrospectively collected. With the median of CAR as the critical value, patients were divided into high CAR group (CAR>0.048) and low CAR group (CAR≤0.048). Then observed the general clinicopathological characteristics and survival status of patients with higher and lower CAR value.ResultsThere were significant differences in NIH classification, tumor diameter, and mitosis between the high CAR group and low CAR group (P<0.05). Compared with the low CAR group, the tumors in the high CAR group had larger diameter, higher mitotic figure, and higher NIH grade. Survival analysis showed that the prognosis of the low CAR group was better than that of the high CAR group (χ2=15.152, P<0.001).ConclusionsCAR is closely related to the malignant index and NIH risk classification of gastric stromal tumors. It can be used as an index for evaluating the malignant degree of gastric stromal tumors, and it is expected to be an important reference factor for clinical NIH risk classification and prognosis.
Objective To explore the effect of foot spacing on multi-directional reach test in the normal elderly and elderly patients with hemiplegia. Methods From October 2019 to December 2020, 50 eligible elderly hemiplegic cases and 50 normal elderly cases were randomly collected. The multi-directional reach tests with foot spacings of 1.0A, 1.5A and 2.0A (A=horizontal distance between bilateral anterior superior iliac spines) were carried out, and the differences and correlations of the maximum horizontal extension distances in the same direction with the three foot spacings were analyzed. Results The statistical results of the normal elderly group (n=50), the left hemiplegic elderly group (n=28), and the right hemiplegic elderly group (n=22) could be described as follows: the maximum horizontal stretching distances in the same direction of left or right were significantly different among the tests with three foot spacings (P<0.05), and the horizontal stretching distance was the largest when the foot spacing was 1.5A; there was no statistically significant difference in the maximum horizontal extension distances in the same direction of forward or backward among the tests with three foot spacings (P>0.05). In the normal elderly, the Pearson correlation coefficients between the maximum horizontal extension distances with the three foot spacings in the left direction were 0.64-0.71 (P<0.05), and those in the right direction were 0.68-0.75 (P<0.05). In the left hemiplegic elderly, the Pearson correlation coefficients between the maximum horizontal extension distances with the three foot spacings in the left direction were 0.72-0.77 (P<0.05), and those in the right direction were 0.78-0.82 (P<0.05). In the right hemiplegic elderly, the Pearson correlation coefficients between the maximum horizontal extension distances with the three foot spacings in the left direction were 0.62-0.77 (P<0.05), and those in the right direction were 0.72-0.88 (P<0.05). Conclusions The results of the study on the normal elderly, left hemiplegic elderly and right hemiplegic elderly are the same. When the normal elderly and hemiplegic elderly are tested in the community and clinic, the fixed foot spacing should be chosen, and the maximal horizontal extension distance on the coronal plane is significantly affected by different foot spacings.
ObjectiveTo explored the influence of disease changes, weight gain, eosinophil levels and other factor in pregnancy women with asthma. MethodsCase records of gestational asthma patients produced in the obstetrics department of Peking University People's Hospital from October 2010 to October 2020 were collected, and refer to electronic medical records of clinics (pre-pregnancy and pregnancy). According to the disease control (asthma related unplanned respiratory clinics, emergency or hospitalization), patients were divided into pregnancy stable group and pregnancy fluctuation group. The basic characteristics, pre-pregnancy asthma control, weight gain during pregnancy and peripheral blood eosinophil level before labor were retrospectively analyzed. The cause of asthma attacks, clinical characteristics and distribution of gestational time in pregnancy fluctuations were described. Peripheral blood eosinophil levels in different period during pregnancy in the stable group were analyzed. ResultsTotally 124 cases of natural pregnancy singleton were enrolled in the study. The age was (32.3±3.9) years old. There were 71 patients in stable group and 53 patients in fluctuation group. The proportion of pre-pregnancy instability in the fluctuating pregnancy group was higher than that in the stable pregnancy group (P<0.05). The proportion of intermittent medication before pregnancy was higher in the fluctuating pregnancy group than in the stable pregnancy group (P<0.05). Peripheral blood eosinophil count before labor and the number of cases with eosinophil count≥0.15×109/L before labor were higher in the fluctuation group (all P<0.05). The proportion of hypertentive diseases in pregnancy and fetal distress in uterus were higher in the fluctuation group (all P<0.05). The common cold was the common trigger factor (38.2%) and asthma recurrences occur between 13 and 36 weeks of gestation (65.8%) in fluctuation group. In further analysis of subgroup (the stable group), peripheral blood eosinophil count in early pregnancy (P<0.05) and pregnant metaphase (P<0.05) were higher than before delivery. The number of cases with eosinophil count>0.15×109/L in pregnant metaphase (P<0.05) was higher than before delivery. ConclusionsAsthma fluctuates during pregnancy is associated with adverse maternal and fetal outcomes. It is very important and critical that asthma control before pregnancy, weight gain management and eosinophil level monitoring of patients with asthma during pregnancy. The whole management is imperative in women with asthma during pregnancy.
Objective To investigate the expression of human leukocyte antigen-G （HLA-G） in hepatocellular carcinoma （HCC） tissues， and to evaluate the prognosis of patients after liver transplantation. Methods The clinical data of 83 patients with HCC who underwent liver transplantation from January 2004 to May 2008 in the Liver Transplantation Center of the Third Affiliated Hospital of Sun Yat-sen University were analyzed retrospectively. The expression of HLA-G in HCC tissues was detected by using immunohistochemical analysis. The Kaplan-Meier method was used to evaluate the cumulative survival rate and tumor-free survival rate. Log-rank test and Cox regression model were used to analyze the single and muti-factor for tumor-free survival rate, respectively. Results Among the 83 patients，there were tumor recurrence in 35 patients （42.2%）. The 1-year，3-year, and 5-year of cumulative survival rate was 97.2%，89.8%, and 43.1%, respectively. The 1-year，3-year， and 5-year of tumor-free survival rate was 93.6%，68.9%, and 38.7%, respectively. The positive rate （68.7%） of HLA-G expression in HCC tissues was significantly higher than that in paracancerous tissues （15.7%）, P＜0.01. A significant association was found between expression of HLA-G and tumor size， vascular invasion, and pathology differentiation （P＜0.05）. Single factor analysis showed that the expression of HLA-G （P＜0.01）， tumor size （P＜0.05）， vascular invasion （P＜0.01）， and pathology differentiation （P＜0.01） effected on tumor-free survival rates of HCC patients after liver transplantation. The tumor-free survival rate in positive expression of HLA-G group was significantly lower than that in negative expression of HLA-G group （P＜0.01）. Cox regression model analysis showed that the expression of HLA-G （P＜0.05）， vascular invasion （P＜0.01）， and pathology differentiation （P＜0.05） were independent risk factors that affected the tumor-free survival rate of HCC patients after liver transplantation. Conclusions There is expression of HLA-G in HCC tissues. The independent risk factors that affecting the tumor-free survival rate of HCC patients after liver transplantation include the expression of HLA-G， vascular invasion, and pathological differentiation. Taking interferential measures for patients with positive expression of HLA-G and strict selection of indication of liver transplantation for HCC can reduce the recurrence rate of tumor.
Automatic detection of pulmonary nodule based on computer tomography (CT) images can significantly improve the diagnosis and treatment of lung cancer. However, there is a lack of effective interactive tools to record the marked results of radiologists in real time and feed them back to the algorithm model for iterative optimization. This paper designed and developed an online interactive review system supporting the assisted diagnosis of lung nodules in CT images. Lung nodules were detected by the preset model and presented to doctors, who marked or corrected the lung nodules detected by the system with their professional knowledge, and then iteratively optimized the AI model with active learning strategy according to the marked results of radiologists to continuously improve the accuracy of the model. The subset 5−9 dataset of the lung nodule analysis 2016(LUNA16) was used for iteration experiments. The precision, F1-score and MioU indexes were steadily improved with the increase of the number of iterations, and the precision increased from 0.213 9 to 0.565 6. The results in this paper show that the system not only uses deep segmentation model to assist radiologists, but also optimizes the model by using radiologists' feedback information to the maximum extent, iteratively improving the accuracy of the model and better assisting radiologists.
