Finally, one patient was diagnosed as congenital muscular dystrophy with mental retardation (CMD-MR) and the other was dystrophytype 2N (LGMD2N). PMTs family has similar sequences. Gene mutations can lead to different degrees of muscular dystrophy with the increase of serum level of CK. α-DG is easy to be misdiagnosed. Genetic examination is beneficial to early diagnosis, prognosis, and genetic counseling.Compassionate use may play an important role in responding to major public health emergencies. The Jinyintan Hospital in Wuhan launched the III phase of clinical trials of antiviral drug-remdesivir on February 6, 2020. As an unapproved drug, remdesivir raised great concerns about compassionate use in China. Compassionate use is therapeutic use of unauthorized drugs outside of clinical trials. It is used for critically ill patients with life-threatening diseases and no effective treatment means in China. Patients voluntarily apply to their medical institutions. The Center for Drug Evaluation, National Medical Products Administration shall conduct scientific and reasonable review, approval, and supervision on patients' application for compassionate medication. By analyzing and comparing the current situation of compassionate use at home and abroad, it is expected to provide thinking for the development of compassionate use system in China.Multiple myeloma (MM) is a highly heterogeneous malignant plasma cell disease. Proteasome inhibitors (PIs) are the first line of medicine for MM. Bortezomib, ixazomib, and carfilzomib are also widely used for MM. Marizomib, oprozomib, and KZR-616 are in clinical trials. However, the drug resistance of PIs in MM is still a problem. The mechanisms for PIs resistance to MM include ubiquitin-proteasome pathway, autophagy lysosome pathway, endoplasmic reticulum stress pathway, cell survival signal pathway, exosome-mediated resistance, and bone marrow microenvironment-mediated resistance.Over the past decade, immunotherapy has been shown to have antitumor activity in a variety of solid tumors, such as melanoma, renal cell carcinoma, and non-small cell lung cancer, keeping a lead in a new era of tumor immunotherapy. Colorectal cancer with high microsatellite instability (MSI-H) or mismatch repair deficient (dMMR) is sensitive to immune checkpoint inhibitors (ICIs). ICIs monotherapy and ICIs combination therapy have made breakthroughs in the treatment of MSI-H/dMMR CRC. At present, a variety of ICIs have been approved for first- and post-line treatment in patients with CRC. However, MSI-H/dMMR type tumors only account for 5% of metastatic CRC, and the most CRCs were microsatellite stable (MSS) or mismatch repair proficient (pMMR). Many clinical trials are exploring effective treatments for patients with MSS/pMMR CRC, and the combination of ICIs and drugs with different mechanisms is expected to improve the efficacy of MSS/pMMR CRC patients. In the future, attention should be paid to finding the potential therapeutic markers of ICIs and the drug resistance mechanism of ICIs, so as to break through the immune tolerance of MSS/pMMR CRC patients.The prevalence of abnormal glucose and lipid metabolism and its relevant diseases has increased year by year, and it has become a problem that threatens human health. Therefore, finding a more effective way to prevent and treat diseases related to abnormal glucose and lipid metabolism has become an urgent public problem. Agmatine is a polyamine substance which widely presents in mammals.It is a metabolite produced by decarboxylation of L-arginine under the action of arginine decarboxylase, hence also known as decarboxylated arginine. Its biological effects have been confirmed. Previous studies have shown that agmatine possesses anti-diabetic effects in diabetic animals. Agmatine not only increases the insulin secretion form β-pancreatic cells to inhibit the hyperglycemia, but also attenuates insulin resistance in rats. Agmatine also plays a positive role in lipid metabolism disorders and related diseases by modulating lipid metabolism and fatty acid oxidation.It is important to evaluate the complex coronary artery disease in the diagnosis and treatment of coronary heart disease.The SYNTAX score based on invasive coronary angiography (ICA) (also referred to as ICA-SYNTAX score) plays a positive role in the selection of revascularization of complex coronary artery disease and the prediction of adverse events.The development of coronary computed tomography angiography (CCTA) technology promotes the clinical application of SYNTAX score (CCTA-SYNTAX score) based on coronary CTA, and also enriches the examination methods of patients with coronary heart disease. The CCTA-SYNTAX score has the advantages of non-invasiveness, simple operation, good reproducibility, and relatively low cost, which can make it play an increasingly important role in the diagnosis of coronary heart disease. A number of foreign studies have confirmed that CCTA-SYNTAX score is highly correlated with ICA-SYNTAX score, which further promotes the study of CCTA-SYNTAX score in revascularization of percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and adverse event prediction.Therefore, the CCTA-SYNTAX score can be an auxiliary method for the ICA-SYNTAX score, as the first choice for preoperative evaluation and postoperative review of patients with coronary heart disease.Atrial fibrillation (AF), a common arrhythmia that usually occurs in patients with heart disease, is one of the leading causes for mortality and disability worldwide. Current drug therapy for AF patients lacks sufficient efficacy and has side effects. Radiofrequency ablation is more effective than traditional drug therapy, but this invasive procedure is associated with potential risks and postoperative recurrence, limiting the clinical benefits for AF patients. Therefore, it is necessary to expand our understanding about the underlying molecular mechanism of AF and to explore the new therapeutic strategies. Long noncoding RNA (lncRNA) is a set of noncoding RNA longer than 200 nucleotides. Growing evidence indicates that lncRNA is involved in numerous pathophysiological processes of AF, such as structural remodeling, electrical remodeling, renin-angiotensin system, abnormal calcium regulation, etc. In addition, lncRNA involved in structural remodeling and electrical remodeling has the potential to be a novel target for the diagnosis and treatment of AF, and lncRNA involved in autonomic nerve remodeling may bring new enlightenment for the prognosis and recurrence of AF.Vascular smooth muscle cell (VSMC) is one of the main cell types in blood vessel wall, and the VSMC apoptosis is involved in the development of atherosclerosis (AS). In early AS, the apoptosis of VSMC is regarded as a compensatory mechanism for neointimal hyperplasia and lumen stenosis. However, this process will also accelerate the rupture of atherosclerotic plaques, resulting in serious cardiovascular complications. More studies on the related genes, RNA, and inducing factors of VSMCs apoptosis in occurrence and development of AS can provide scientific strategies for prevention and treatment of AS in different periods.Obstructive sleep apnea (OSA) is a kind of sleep-related breathing disorder, involving multiple organs and systems, which can lead to cognitive impairment. At present, the pathophysiological mechanism of cognitive impairment related to OSA is not clear. HDAC inhibitor It is still unknown whether continuous positive airway pressure (CPAP) has therapeutic effect on cognitive impairment in patients with OSA. These patients repeatedly experience intermittent hypoxia and have sleep fragmentation, which results in abnormal brain structure and function, characterizing by extensive cognitive impairment. Appropriate CPAP can correct the abnormal pathophysiological process of OSA patients, restore brain structure and function to a certain extent, and improve cognitive function. Domestic OSA patients have poor acceptance and compliance to CPAP, while the therapeutic effect of CPAP depends on the timing of treatment and compliance, so many patients do not get effective treatment. Systematically expounding the influence of CPAP on the cognitive function of patients with OSA can help clinicians and patients improve their understanding of CPAP treatment and establish a correct concept of early and standardized treatment.

Previous studies on brain MRI image segmentation, such as threshold method, boundary detection method, and region method did not achieve good performance in complex scenes. Based on the deep learning segmentation technology, this study constructed a neural network model by using the algorithm of atrous convolution combined with conditional random field (CRF) to segment the thalamus, caudate nucleus, and lenticular nucleus in brain MRI, which laid a good foundation for MRI diagnosis of brain diseases.

A total of 1 200 MRI-Flair images of the brain were randomly selected, and 3 anatomical structures of thalamus, caudate nucleus, and lenticular nucleus were manually labeled, of which 1 000 were used as training data sets and 200 were used as test data sets. The neural network model was established by using deep convolutional neural networks (DCNN) combined with CRF algorithm. The training data set was input into the model, and the parameterized neural network model was obtained after iteration for 30 000 times. The test data set was used to evaluate, test, and output the predicted image.

The model optimization results showed that the new brain MRI segmentation model DeepXAG had the highest accuracy. Therefore, DeepXAG was selected as the segmentation algorithm. The mean intersection over union (mIOU) of the DeepXAG model was 72.3%, which was significantly higher than other classical segmentation algorithms (CRF-RNN1, FCN-8s2, DPN3, RefineNet4, and PSPNet5).

The DeepXAG algorithm has good accuracy and robustness in segmenting the anatomical structure of brain MRI images.

Coagulation dysfunction caused by large-area burns is an independent risk factor for the 28-day mortality of adult patients. However, whether early (48 hours after admission) correction of coagulopathy can reduce the 28-day mortality of adult patients with large-area burns has not been clarified. The purpose of this study was to investigate the effect of early correction of coagulopathy on the 28-day mortality in the adult patients with large-area burns.

Medical records of burn patients with blood transfusion who were hospitalized in the Department of Burn, First Affiliated Hospital of Nanchang University from April 2014 to July 2019 were retrieved. Among them, 573 adult patients with large-area burns were selected as the research subjects. The patients were divided into an experimental group (patients had early rectification of coagulation dysfunction,

=290) and a control group (patients without early rectification of coagulation dysfunction,

=283). The basic clinical data and prognostic indicators ostically significant (χ

=14.270,

<0.001).

The burn area/TBSA and III° burn area are independent risk factors for 28-day mortality in adult patients with large-area burns. The 48-hour frozen plasma transfusion volume and 48-hour correction of coagulopathy are independent protective factors. Early correction of coagulation dysfunction is beneficial to reducing the 28-day mortality for the adult patients with large-area burns.
