In recent years, the incidence of dry eye disease(DED)is increasing, positioning it as one of the most prevalent diseases affecting the ocular surface. Inflammatory response is the pathological basis of DED, involving various inflammatory mediators and inflammatory signaling pathways. Consequently, anti-inflammatory treatment emerges as a fundamental strategy for preventing and managing DED. This review summarizes the classic inflammatory factors involved in the development and progression of DED, including interleukins, tumor necrosis factor, matrix metalloproteinases, chemokines, and cell adhesion molecules. It also discusses the relevant inflammatory signaling pathways: the MAPKs pathway, NF-κB pathway, Wnt pathway and TLR pathway. Additionally, this review addresses the mechanisms of action and alterations in relevant biomarkers associated with current first-line recommended anti-inflammatory therapies, including corticosteroids, immunosuppressants, nonsteroidal anti-inflammatory drugs, and traditional Chinese medicine approaches to inflammation management. This comprehensive overview aims to enhance understanding of the inflammatory mechanisms underlying DED while exploring future therapeutic prospects.

Objective:Based on the principle of neuroplasticity, to explore the effect of square dancing on elderly patients with subjective cognitive decline (SCD).Methods:SCD patients in the main urban area of Nanjing were selected in this quasi experimental research from March to September 2022 and divided into experimental group and control group according to whether the subjects were willing to participate in square dance intervention, with 30 cases in each group. The experimental group received 6 months of square dancing intervention, and the control group received routine nursing. The differences of cognition, memory, language, executive ability, daily living ability and anxiety and depression were compared between the two groups.Results:Twenty-seven cases in the experimental group and 28 cases in the control group completed the intervention. After intervention, the scores of Montreal Cognitive Assessment Scale-15, the Geriatric Depression Scale, Hamilton Anxiety Scale and Trail Making Test B were 27.0(26.0, 28.0), 2.0(1.0, 4.0), (4.30 ± 2.04) points and (112.48 ± 25.42) seconds, respectively. Compared with the control group of 26.0 (24.0, 27.0), 4.0 (2.0, 5.8), (5.89 ± 1.45) points and (133.21 ± 32.39) seconds, the differences were statistically significant ( Z = -2.24, -2.72, t = - 2.05, -2.64, all P<0.05). Conclusions:Square dancing can improve the cognitive function of elderly patients with SCD, promote the improvement of memory, language, executive function and daily living ability, and effectively relieve anxiety and depression symptoms.

It was generally believed that muscular atrophy of paralyzed limbs after stroke was due to disuse. However, recent studies have found that secondary lesions of motor neurons in the contralateral anterior horn of the spinal cord and the decrease of motor units lead to denervation, which plays an essential role in muscular atrophy and muscle fiber type transition. This article reviews the phenomenon and mechanism of muscular atrophy and denervation of paralyzed limbs after stroke, to provide a reference for clinical evaluation and experimental research.

A wearable wireless health monitoring system for drug addicts in compulsory rehabilitation centers was proposed. The system can continuously monitor multiple physiological parameters of drug addicts in real time, and issue early warning information when abnormal physiological parameters occur, so as to play the role of timely medical practice. In addition, this study proposes a convolutional neural network (CNN)model, which can evaluate the health status of drug addicts based on multiple physiological parameters. Experiments show that the model can be applied to the task of body state recognition in the open physiological parameter data set, and the recognition accuracy can reach up to 100% in a single physiological parameter data set; when the whole physiological data set is used, the recognition accuracy can reach 99.1%. The recognition accuracy exceeds the performance of the traditional pattern recognition method on this task, which verifies the superiority of the model.

Objective To explore the related factors of diarrhea onset in critically ill patients during early enteral nutrition (EEN). Methods Thirty Zhejiang Provincial Emergency Intensive Care Units (EICU) and ICU to implement EEN support for critically ill patients from July 2016 to August were enrolled, and the incidence of diarrhea within 1 week after EEN administration was observed. The patients were divided into a diarrhea group and a non-diarrhea group according to whether diarrhea occurred or not during EEN. The basic status data [sex, age, body mass index (BMI), albumin, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), nutritional risk screening (NRS2002), major disease diagnosis], and EN status (feeding route, infusion method, EN type, amount of EN on days 4 and 7), and clinical treatment (applying following treatments or not: mechanical ventilation and its duration, vasoactive drugs, gastrointestinal motility drugs, probiotics) and clinical outcomes (survival after discharge or not) were collected in two groups. Multivariate Logistic regression analysis was performed on the indexes with statistically significant differences obtained from the univariate analysis to screen out the relevant risk factors of occurrence of diarrhea in critically ill patients during EEN administration. The receiver operating characteristic curve (ROC) was drawn to analyze the predictive value of each risk factor for occurrence of diarrhea in critically ill patients with EN therapy. Results Of the 510 critically ill patients who underwent EEN, 156 had diarrhea, 70.5% (110/156) had diarrhea within 4 days of EEN, most diarrhea lasts for 3 days and most frequency of diarrhea was 3-4 times a day. The univariate analysis showed that the age of patients in the diarrhea group was significantly higher than that in the non-diarrhea group (years:69.42±17.94 vs. 65.76±17.69), the mechanical ventilation time and ICU hospitalization time were significantly longer than those of non-diarrhea group [mechanical ventilation time (days): 8 (5, 14) vs. 8 (4, 9), ICU hospitalization time (days): 11.5 (8.0, 19.0) vs. 9.0 (6.0, 14.0)], the proportion of probiotics used and the proportion of feeding by nasal tube were significantly higher than those of non-diarrhea group [proportion of probiotics: 26.9% (42/156) vs. 14.4% (51/354), proportion of nasal tube feeding: [26.9% (42/156) vs. 14.4% (51/354)]. Multivariate Logistic regression analysis showed that the use of probiotics was a protective factor for diarrhea during EEN in critically ill patients [odds ratio (OR) = 0.447, 95% confidence interval (95%CI) = 0.273-0.730, P = 0.001]. ROC analysis showed that the area under the curve (AUC) of probiotics predicting diarrhea was 0.598 (95%CI = 0.554-0.640), P < 0.001, sensitivity was 35.9%, and because AUC was less than 0.7, the accuracy and sensitivity of predicting diarrhea with probiotics was considered to be relatively poor. Conclusion The incidence of diarrhea is high in EEN in critical illness patients and its occurrence is related to various factors. The addition of probiotics can reduce the incidence of diarrhea.
