Serious motor dysfunction is the leading cause of disability in individuals with stroke. Rehabilitation is the most effective intervention. Taking “stroke” “cerebrovascular accident” “rehabilitation” “motor dysfunction” and other key words, the relevant studies published from January 2015 to January 2020 were searched in Web of Science database to explore the advance in rehabilitation of motor dysfunction in individuals with stroke based on basic and clinical researches. Basic researches mainly focused on the mechanism of neural plasticity, neural loop and various intervention measures, and clinical researches mainly focused on novel rehabilitation intervention technologies for motor dysfunction in individuals with stroke. In addition, mechanism and rehabilitation are still two hotpots in the field of the disease. This paper reviews the search results in order to provide reference for subsequent relevant clinical work and scientific research.
ObjectiveTo detect the development of retinal neovascularization (NV) induced by metabolic acidosis in neonatal rats and investigate the relationship between the occurrence of NV and vascular endothelial growth factor (VEGF). MethodsA total of 425 newborn Sprague-Dawley rats in experimental group underwent tubal feeding of NH4Cl (535 mg/kg) with the concentration of (50 mg/ml) (twice per day) from the 2nd day after the birth for 6 days and followed by a period of recovery. Additional 150 neonatal rats were in the control group without the tubal feeding. The rats were executed at the 3rd, 5th, 8th, 10th, 13th, 20th day after birth respectively. The retinal vessels were evaluated through retinal stretched preparation andadenosine diphosphatase (ADPase) staining; VEGF in retina was detected by enzymelinked immunosorbent assay(ELISA).ResultsIn the experimental group, the incidence of retinal NV at the 3rd, 5th, 8th, 10th, 13th, 20th day after birth was 0%，9%，26%，55%，19%, and 0% respectively. At the 3rd day, the expression of VEGF protein was lower in experimental group ［（101.1±14.2 ）pg/mg］ than that in the control group ［（133.2±15.9） pg/mg］（P＝0.004）, while at the 8th day it was higher in experimental group［(98.4±19.2) pg/mg］than that in the control group［（78.1±8.7） pg/mg］（P=0.028). There was no significant difference between the two groups at the 5th, 10th, 13th, and 20th day (Pgt;0.05). ConclusionsMetabolic acidosis may induce NV by injuring the developing retinal vessels. Retinal NV induced by acidosis relates to VEGF. (Chin J Ocul Fundus Dis, 2005,21:296-299)

In order to improve the accuracy and reliability of the electrodes implant location when using spinal functional electrical stimulation to rebuild hindlimb motor function, we measured the distributions of function core regions in rat spinal cord associated with hindlimb movements. In this study, we utilized three-dimensional scanning intraspinal microstimulation technology to stimulate the rat spinal cord to generate hip, knee and ankle joint movements, and acquired the coordinates of the sites in spinal cord which evoked these movements. In this article, 12 SD rats were used to overcome the individual differences in the functional region of the spinal cord. After normalized and overlaid the messages, we obtained the function core regions in spinal cord associated with ankle dorsiflexion movement, hip flexion movement, hip extension movement and hip adduction movement. It provides a reference for rebuilding the hindlimb movement function with micro-electronic neural bridge.
Objective To investigate the clinical application value of GeneXpert Mycobacterium tuberculosis (MTB)/ rifampin (RIF) in urine samples for tuberculosis diagnosis. Methods The patients with clinically highly suspected tuberculosis admitted to West China Hospital of Sichuan University between January 1, 2018 and June 1, 2023 were selected retrospectively. The diagnostic efficacy of urine GeneXpert MTB/RIF detection, such as sensitivity, specificity, positive predictive value, and negative predictive value, were retrospectively analyzed to evaluate its clinical value in the diagnosis of tuberculosis. Correlation analysis was further conducted to explore the correlation between positive levels of GeneXpert MTB/RIF in urine samples and laboratory test indicators. Results A total of 400 patients were included. Among them, 163 cases were in the clinical tuberculosis group and 237 cases were in the clinical non tuberculosis group. In the clinical tuberculosis group, 112 cases were urogenital tuberculosis patients and 51 cases were non-urogenital tuberculosis patients. The sensitivity, specificity, positive predictive value, and negative predictive value of urine GeneXpert MTB/RIF in the diagnosis of tuberculosis were 55.2%, 97.5%, 93.8% and 76.0%, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of urine GeneXpert MTB/RIF in the diagnosis of urogenital tuberculosis were 65.2%, 92.0%, 76.0% and 87.2%, respectively, and the diagnostic sensitivity was further improved. Correlation analysis showed that the positive degree of urine GeneXpert MTB/RIF was correlated with the levels of hemoglobin, serum total protein, blood serum albumin, and other indicators. Conclusions Urine GeneXpert MTB/RIF detection offers high sensitivity and specificity in the diagnosis of tuberculosis, especially in urogenital tuberculosis, which is helpful for the early and rapid diagnosis of tuberculosis patients. The positive degree reported by the GeneXpert MTB/RIF in urine may indicate disease severity.
ObjectiveTo explore the application and effect of clinical nursing pathway based on information-knowledge-attitude-practice (IKPA) theory in percutaneous renal needle biopsy.MethodsThis is a historical control study. A total of 460 patients who underwent percutaneous renal biopsy in West China Hospital of Sichuan University between April and December 2020 were prospectively recruited as the pathway group, and a clinical nursing pathway based on IKAP theory was implemented. By contrast, the data of 617 patients who underwent percutaneous renal biopsy and received routine care in the same hospital between April and December 2019 were retrospectively collected as the control group. The length of hospital stay, hospitalization expenses, the incidences of postoperative complications (macroscopic haematuria, perirenal hematoma, and acute urinary retention), the incidence of postoperative postural hypotension, and the management enrollment rate of chronic kidney disease patients were compared between the two groups.ResultsThe length of hospital stay [median (lower quartile, upper quartile): 8 (7, 11) vs. 8 (7, 12) d] and the hospitalization expenses [median (lower quartile, upper quartile): 7380.50 (6401.86, 8789.21) vs. 8167.00 (6816.50, 10044.50) yuan] were less in the pathway group than those in the control group, the incidences of postoperative macroscopic haematuria (1.52% vs. 6.97%) and perirenal hematoma (2.61% vs. 5.02%) were lower in the pathway group than those in the control group, the management enrollment rate of chronic kidney disease patients was higher in the pathway group than that in the control group (26.09% vs. 6.16%), and the differences between the two groups were statistically significant (P<0.05). The differences in the incidences of acute urinary retention (8.26% vs. 11.18%) and postoperative postural hypotension (0.00% vs. 0.81%) between the two groups were not statistically significant (P>0.05).ConclusionThe application of clinical nursing pathway in percutaneous renal needle biopsy can effectively reduce the length of hospital stay and hospitalization expenses, and improve the management enrollment rate of chronic kidney disease patients.
Objective To explore the role of using a workshop combined with diversified teaching model in undergraduate general practice. Methods Undergraduate students who enrolled in the Class 2022 general medicine course of Shanghai Jiao Tong University School of Medicine were selected between February and June 2023. Two classes were selected from undergraduate students who enrolled in the Class 2022 general medicine course using a simple random sampling method. One class was selected as the control group (using the workshop teaching mode), while the other class was selected as the experimental group (using the workshop combined with diversified teaching mode). The evaluation of teaching effect, teaching satisfaction, career intention and final scores of the control group and the experimental group were compared. Results A total of 120 students were included, with 60 students in each group. There was no statistically significant difference in the gender, age, and previous general medicine course exam scores between the two groups (P>0.05). The evaluation of teaching effect by the experimental group was higher than that of the control group (P<0.05). The teaching satisfaction scores of the experimental group on teaching atmosphere (85.16±9.44 vs. 81.65±8.15), teaching mode (86.30±9.12 vs. 79.27±9.33), and teaching management (84.20±7.05 vs. 80.10±7.15) were higher than those of the control group (P<0.05). The experimental group had a higher career intention than the control group (45 vs. 32 people; χ2=6.125, P=0.013). The theoretical course scores (71.77±7.10 vs. 66.14±7.45), internship scores (10.32±3.34 vs. 8.58±2.56), and total scores (82.09±9.36 vs. 74.58±8.45) of the experimental group were higher than those of the control group (P<0.05). Conclusion The application of workshop combined with diversified teaching mode in undergraduate general medicine course teaching can improve students’ evaluation of teaching effect, teaching satisfaction and final scores, as well as change students’ career intention.
Objective To evaluate the reliability and validity of the Chinese version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) in preoperative anxiety in patients with local anesthesia. Methods From May to December 2020, a convenient sampling method was used to conduct an APAIS questionnaire survey on patients undergoing percutaneous renal biopsy in the Department of Nephrology, West China Hospital, Sichuan University, and the reliability and validity of the scale were analyzed. ResultsA total of 460 questionnaires were distributed and 444 valid questionnaires were returned, with a valid response rate of 96.5%. The Cronbach α of APAIS was 0.896, the Guttman split-half reliability was 0.811, and the content validity index was 0.891. The model fit was 12.122 for the chi-square fit index/degree of freedom, 0.916 for the goodness-of-fit index, 0.902 for the value-added fit index, 0.079 for the root mean square error of approximation, and 0.946 for the comparative fit index. The APAIS anxiety subscale score was positively correlated with the 7-item Generalized Anxiety Disorder Scale score (r=0.518, P<0.001). Conclusion The APAIS has good reliability and validity for evaluating the level of preoperative anxiety in patients with local anesthesia, but the application of the scale in other conditions requires further testing.
In recent years, the prevalence of carbapenem-resistant Enterobacterales (CRE) has been remarkably increasing. Infections caused by CRE have significantly increased the burden on patients both medically and economically, and the CRE often leads to outbreaks of healthcare-associated infections. It has now become a global public health concern. Consequently, international organizations and academic societies/associations, including the World Health Organization, have developed corresponding prevention and control guidelines. This article provides a detailed introduction to the background, principles, key understandings, and implementation recommendations of China’s Standard for Prevention and Control of Carbapenem-resistant Enterobacterales (WS/T 826－2023). The aim is to enhance the recognition of healthcare workers and medical administrators to prevent and control CRE and to provide detailed technical guidance for healthcare facilities in responding to the spread of CRE, thus ensuring medical quality and patient safety.
