ObjectiveTo investigate the relationship of diaphragmatic mobility (ΔM) evaluated by ultrasonography with quality of life and athletic ability in patients with chronic obstructive pulmonary disease (COPD) , and analyze the factors those affect the diaphragmatic mobility.MethodsA total of 48 male patients with stable COPD were recruited in the study. The body height, body weight, diaphragmatic mobility, airflow obstruction (FEV1%pred), and exercise capacity (6MWD) were measured. The quality of life was assessed using the St. George’s Respiratory Questionnaire (SGRQ).ResultsThe minimum value of ΔM was 1.89 cm and the maximal value was 8.11 cm in the COPD patients. There were significant correlationship between ΔM and the SGRQ score of the total score, symptom score, impact points, activity points and 6MWD, with correlation coefficients of –0.474, –0.416, –0.432, –0.502 and 0.536, respectively. Multivariate stepwise regression analysis showed that the factors influencing ΔM were height (β=0.407, P=0.021) and FEV1%pred (β=–0.391, P=0.035).ConclusionsDiaphragmatic mobility and quality of life are closely related in COPD patients. The height and FEV1%pred have the greatest effect on diaphragmatic activity. The smaller diaphragm mobility is relevant to the worse quality of life and the smaller activity capacity.
目的:調查在校醫學生對醫療相關法律法規及醫患關系的認知,為醫學生教育提出建議。方法:使用自制調查問卷,對四川大學華西校區不同專業方向及學歷層次的在校醫學生進行整群隨機抽樣,將所得數據錄入計算機建立數據庫,進行統計分析。結果:(1) 在對醫療法規相關知識的知曉率上,研究生高于本科生,臨床相關專業高于非臨床相關專業;(2) 醫學生對醫療法規相關知識及醫患關系的認知主要來自于課外,來自于課堂教學的很少,并且大多數醫學生支持開設相關法律課程;(3) 過半數的醫學生認為醫患溝通不足是導致醫療糾紛的首要原因;(4) 大多數醫學生認為目前醫患之間存在信任危機,且這種狀況對他們今后的擇業觀造成了負面影響。結論:在醫學生中開展相關醫療法律課程等人文學科課程是符合當前國內醫療衛生事業發展需要的。

OBJECTIVE To inquire the indications, contraindications, and operative methods of the treatment of spastic cerebral palsy with selective posterior rhizotomy (SPR), and to improve the therapeutic results and decrease the incidence rate of complications. METHODS The documents about SPR were extensively consulted, and the mechanisms, indications, contraindications, operative methods, muscular tension changes and complications after operation were reviewed. RESULTS With the methods of SPR, I alpha fibers of afferent nerve were selectively amputated, reflex circle of spinal cord was locked, and the muscular tension was decreased, so myospasm was removed. The results after operation and incidence rate of complications were closely related to the indications. The therapeutic results were better when the percent of spinal nerve rhizotomy was less than 50%. CONCLUSION It is a good method for the treatment of spastic cerebral palsy.
ObjectiveTo investigate the current status and influencing factors of self-care behavior of non-dialysis patients with chronic kidney disease (CKD).MethodsA total of 336 patients with CKD were investigated by a general data questionnaire, the CKD Self-care Behavior Scale, Social Support Scale, Generalized Anxiety Self-assessment Scale, and 9-item Patients Health Questionnaire through WeChat platform, and the influencing factors of self-care behavior were explored by binary logistic regression analysis.ResultsThe median score of self-care behavior of CKD patients without dialysis was 60, and the patients with median and high level of self-care behavior accounted for 97.6%. The score of self-care behavior of CKD patients without dialysis was positively correlated with the total score of social support (r=0.210, P<0.001), objective support score (r=0.127, P=0.020), subjective support score (r=0.195, P<0.001), and social support utilization score (r=0.164, P=0.002), and negatively correlated with the anxiety score (r=–0.132, P=0.015), depression score (r=–0.230, P<0.001), body mass index (r=–0.181, P=0.001), and systolic blood pressure (r=–0.168, P<0.001). The results of binary logistic regression analysis showed that the influencing factors of non-dialysis CKD patients’ self-care behavior were gender [(odds ratio, OR)=2.179, 95% confidence interval, CI (1.134, 4.187), P=0.019], systolic blood pressure [OR=0.967, 95%CI (0.947, 0.987), P=0.002], and depression score [OR=0.844, 95%CI (0.765, 0.931), P=0.001].ConclusionsThe self-care behavior of CKD patients without dialysis is at the median and high level. Healthcare workers can improve the self-care behavior of CKD patients by reducing their negative emotions such as depression, and guiding patients to carry out blood pressure management, to delay the progress of the disease.

Objectives To detect expressions of heat shock protein 70 (HSP70) and glial fibrillary acidic protein (GFAP) , and to estimate the post-injury interval after concussion of brain via the ratios of percentage of HSP70/GFAP-positive cells. Methods We established a brain concussion model of rat. Tissue levels of HSP70 and GFAP were determined by immunohistochemical staining at different time points after injury. Finally, the relationship between the ratio of percentage of HSP70/GFAP-positive cells and the post-injury interval was measured. Results The ratio of percentage of positive cells (increased from 7.15 to 11.73) and the percentage of HSP70-positive cells (P<0.05, compared with control group) increased, and the percentage of GFAP-positive cells did not change remarkably (P<0.05, compared with control group); the post-injury interval was between 0.5 hour and 3 hours. High ratio (>6.66) and high percentage of HSP70 and GFAP-positive cells (P<0.05, compared with control group) indicated the post-injury interval was between 3 and 12 hours. A low ratio (<6.66) and high percentage of HSP70 and GFAP-positive cells (P<0.05, compared with control group) suggested that the post-injury interval was later than 12 hours. Conclusion By analyzing the variation rule of the ratio of percentage positive cells after brain concussion, the post-injury interval after concussion of brain could be estimated.
Objective To use bibliometrics to identify research hotspots and emerging trends in the use of artificial intelligence (AI) in healthcare-associated infections (HAI), as well as to offer a resource for more relevant research. Methods The literature on AI and HAI from the Science Citation Index Expanded database of the Web of Science Core Collection was retrieved through computer searches, covering the period from January 1, 1994, to January 22, 2024. VOSviewer (v1.6.19) and CiteSpace (v6.1. R6) software were utilized for bibliometric analysis, creating knowledge maps that include research cooperation networks and keyword analysis. Results A total of 305 documents were included, and both the number of early publications and the frequency of citations were at a very low level for a long time before showing an annual increase trend after 2018. The United States had the most published documents among the 50 countries/regions from where they were sourced. Harvard University was the scientific research institution with the most publications, while Professor Evans HL of the Medical University of South Carolina was the scholar with the most publications. Research on AI in the field of HAI primarily focused on three aspects: AI algorithms and technologies, monitoring and prediction of HAI, and the accuracy of HAI diagnosis and prediction. These findings were based on keyword co-occurrence and clustering analysis. Conclusions A new phase of AI research in the subject of HAI has begun. More in-depth research can be done in the future for the hot direction, as there is still a gap between China’s academic accomplishments in this subject and the advanced level of the world.
OBJECTIVE: To investigate the mechanism of overhealing alleviation by salvia miltiorrhiza (SM) in wound healing. METHODS: Fibroblasts were cultured in vitro, and SM was applied with different concentrations (40, 80, 160 and 320 micrograms/ml) and time(the 1st, 2nd, 3rd, 4th and 5th days) to influence their autocrine. The levels of transforming growth factor-β1 (TGF-β1) and epidermal growth factor (EGF) were determined by ELIAS and radioimmunoassay respectively. RESULTS: The SM could inhibit autocrine of TGF-β1 by fibroblasts (P lt; 0.05). However, it did not affect autocrine of EGF (P gt; 0.05). CONCLUSION: The above results indicate that SM reduces overhealing by inhibiting the autocrine of TGF-β1 selectively.
