ObjectiveTo investigate the changes in cerebral blood perfusion in patients with acute cerebral infarction after taking Tongnaoyin， a traditional Chinese medicine， based on head and neck computed tomography （CT） angiography （CTA） combined with brain CT perfusion imaging （CTP）. MethodA total of 240 patients with cerebral infarction of phlegm and blood stasis syndrome treated in Jiangsu Province Hospital of Traditional Chinese Medicine from March 2018 to September 2023 were randomly divided into a control group （99 cases） and a Tongnaoyin group （141 cases）. Based on the guidelines， the control group was treated with conventional treatment such as anti-aggregation， anticoagulation， lipid-lowering and plaque stabilization， brain protection， and supportive treatment. The Tongnaoyin group was treated with Tongnaoyin of 200 mL in warm conditions in the morning and evening on the basis of the control group. Both groups underwent CTA combined with CTP within 24 hours after admission， and they were reexamined by CTA and CTP in the sixth month after admission. The degree of intracranial artery stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial （NASCET） method. The relative cerebral blood volume （rCBV）， relative cerebral blood flow （rCBF）， mean transit time （MTT）， and time to peak （TTP） of the lesion area before and after treatment were compared. The adverse outcomes of the two groups within six months after discharge were compared. ResultCompared with the group before treatment， the degree of vascular stenosis in the Tongnaoyin group was significantly reduced， and the difference was statistically significant （Z=105.369，P<0.05）. Compared with the control group after treatment， the improvement rate of vascular stenosis in the Tongnaoyin group was higher （χ²=84.179，P<0.01）， and the curative effect was better.After treatment， the rCBV and rCBF of patients in the Tongnaoyin group were significantly increased， and the difference was statistically significant （P<0.01）. MTT and TTP showed a trend of shortening， but the difference was not statistically significant. There was no statistically significant difference in rCBV， rCBF， MTT， and TTP in the control group. Compared with those in the control group after treatment， the rCBV and rCBF in the Tongnaoyin group were significantly increased， while MTT and TTP were significantly reduced （P<0.01）. After six months of discharge， the risk of poor prognosis in the Tongnaoyin group was significantly reduced compared with the control group （P<0.05）. ConclusionTongnaoyin has a good effect on improving cerebral blood perfusion in patients with acute cerebral infarction. It can be used as an effective supplement for the conventional treatment of ischemic stroke to improve clinical efficacy.

Acute myocardial infarction with cardiogenic shock (AMI-CS) refers to the rapid decrease in cardiac output in a short period of time, and it leads to severe insufficient perfusion of various organs and causes systemic microcirculatory dysfunction, which is the most common cause of the death of patients with acute myocardial infarction (AMI). At present, the main strategy for clinical treatment of AMI-CS is revascularization, which reduces the mortality of AMI-CS. However, myocardial ischemia and reperfusion can cause ischemia/reperfusion (I/R) injury, induce myocardial mitochondrial dysfunction, and a large amount of reactive oxygen species (ROS) accumulation. Mitochondrial-mediated apoptosis of cardiomyocytes is the main reason of cardiomyocyte death during reperfusion injury. This article summarizes the role of mitochondrial in AMI-CS, which focus on three aspects of mitochondrial permeability transition pore (mPTP) opening, mitochondrial autophagy and mitochondrial fusion/division. It is expected to provide new ideas for clinical AMI-CS and identify potential complications targets.

With the increasing prevalence of chronic obstructive pulmonary disease (COPD) and the extremely high mortality, disability, symptom burden and dysfunction, as well as the need for continuous drug management and care and increased rehospitalization rate, it brings patients, families and even society huge economic burden. The transitional care model provides non-drug treatment method to help patients get through the transition period safely and steadily, it also improves patients' self-care ability, quality of life and reduce hospital readmission. This review will start from the concept of disease management in transitional period, elaborate on the problems and core elements of transitional caring, then discuss the application of advanced practice nurse-dominated transitional caring mode in COPD, so as to provide theoretical and practical basis for improving the quality of chronic diseases management in China.

Objective To reconcile previous studies on the impact of transitional nursing intervention on quality of life in patients with chronic obstructive pulmonary disease (COPD) after discharge from the Chinese population. Methods PubMed, EMBASE, Cochrane Library, Clinical Trial, CBM, Joanna Briggs Institute Library, MEDLINE, Wanfang database and CNKI database, Vip database were searched by computer. The literatures about the influence of transitional nursing on the quality of life of COPD patients were searched until January 1, 2018. the data were analyzed by Rev Man 5.3 software. The results showed that P<0.05 on both sides was statistically significant. Results Five clinical studies were included, and the data were combined according to the symptom, activity, social psychology and St.George's Respiratory Questionnaire (SGRQ) total score in the SGRQ scale. Mean difference and its 95％confidence interval of symptoms, activities, social psychology and SGRQ score were-13.09 (-18.71,-7.48), 12.05 (-14.55,-9.45),-17.87 (-22.27,-13.46) and-15.42 (-19.74,-11.10) (Z=4.57-9.42, all P <0.05). Conclusions The transitional nursing has a significant positive effect on improving the quality of life among patients with COPD, which can effectively improve the psychosocial status of patients, and make the patients respond more actively to the problems in the process of treatment and rehabilitation.

Objective To reveal the pathophysiological changes of sepsis, the plasma metabonomics of septic rats was determined and differential metabolites were determined by gas chromatography-mass spectrometry (GC-MS). Methods Male Spraguee-Dawley (SD) rats about 8 weeks were randomly divided into sham group (n = 18) and sepsis group (n = 24). Cecal ligation and puncture (CLP) was used to build sepsis model, while cecum was kept intact only in the sham group. 6 hours after the operation, rats were anesthetized, and blood was harvested through heart thoracotomy. Then the plasma metabonomics was detected by GC-MS and metabolic profile analysis was performed to find the relative differential metabolites.Results Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) showed that the metabolic profiling of the sepsis group was significantly different from the sham group. 259 kinds of metabolites were got by GC-MS, and 69 kinds of differential metabolites were found between sham group and sepsis group, in which 23 differential metabolites were related to amino acid metabolism. Compared with sham group, the contents of putrescine, N-glutamic acid, hydroxynorvaline, 3-cyanuric acid, D-alanyl-D-alanine and urea in the plasma of septic rats increased significantly, which ratios of sepsis/sham group were 10.876, 6.394, 2.800, 2.226, 1.323, 1.203, respectively (allP < 0.05). On the other hand, the contents of oxygen generation of proline, citrulline, glutamine, su-beta-hydroxy aspartic acid, citric acid, N-methyl-DL-alanine, serine, lysine, threonine, N-formyl-L-methionine, methionine, alanine, nicotinuric acid, N-methyl-L-glutamic acid, trans-4-hydroxy-L-proline, proline, L-glutamic acid in the plasma of septic rats decreased significantly, which ratios of sepsis/sham group were 0.858, 0.853, 0.834, 0.816, 0.816, 0.814, 0.813, 0.801, 0.793, 0.792, 0.774, 0.766, 0.748, 0.727, 0.716, 0.674, 0.603, respectively (allP < 0.05).Conclusions Through the GC-MS analysis of plasma metabonomics of septic rats, we found abnormal energy metabolism changes. The content of amino acid in plasma might be a method to evaluate the energy metabolism status of sepsis.
