RESUMEN
OBJECTIVE: To compare the clinical effects of coronary artery bypass grafting (CABG) between the left anterior small thoracotomy (LAST) and lower-end sternal splitting (LESS) approaches for coronary artery disease. METHODS: In total, 110 patients who underwent LAST from October 2015 to December 2020 in Tianjin Chest Hospital were selected as the observation group. Patients who underwent the LESS approach during the same period were analyzed. The propensity score was calculated by a logistic regression model, and nearest-neighbor matching was used for 1:1 matching. RESULTS: The length of hospital stay and ventilator support time were significantly shorter in the LAST than LESS group. The target vessels in the obtuse marginal branch and posterior left ventricular artery branch grafts were significantly more numerous in the LAST than LESS group, but those in the right coronary artery graft were significantly less numerous in the LAST group. CONCLUSIONS: CABG using either the LAST or LESS approach is safe and effective, especially in low-risk patients. The LAST approach can achieve complete revascularization for multivessel lesions and has the advantages of less trauma and an aesthetic outcome. However, it requires a certain learning curve to master the surgical techniques and has specific surgical indications.

RESUMEN
Objective:To investigate and summarize the chest CT imaging features of patients with novel coronavirus pneumonia (COVID-19), bacterial pneumonia and other viral pneumonia.Methods:Chest CT data of 102 patients with pulmonary infection due to different etiologies were retrospectively analyzed, including 36 patients with COVID-19 admitted to Hainan Provincial People's Hospital and the Second Affiliated Hospital of Hainan Medical University from December 2019 to March 2020, 16 patients with other viral pneumonia admitted to Hainan Provincial People's Hospital from January 2018 to February 2020, and 50 patients with bacterial pneumonia admitted to Haikou Affiliated Hospital of Central South University Xiangya School of Medicine from April 2018 to May 2020. Two senior radiologists and two senior intensive care physicians were participated to evaluated the extent of lesions involvement and imaging features of the first chest CT after the onset of the disease.Results:Bilateral pulmonary lesions were more common in patients with COVID-19 and other viral pneumonia, and the incidence was significantly higher than that of bacterial pneumonia (91.6%, 75.0% vs. 26.0%, P < 0.05). Compared with other viral pneumonia and COVID-19, bacterial pneumonia was mainly characterized by single-lung and multi-lobed lesion (62.0% vs. 18.8%, 5.6%, P < 0.05), accompanied by pleural effusion and lymph node enlargement. The proportion of ground-glass opacity in the lung tissues of patients with COVID-19 was 97.2%, that of patients with other viral pneumonia was 56.2%, and that of patients with bacterial pneumonia was only 2.0% ( P < 0.05). The incidence rate of lung tissue consolidation (25.0%, 12.5%), air bronchial sign (13.9%, 6.2%) and pleural effusion (16.7%, 37.5%) in patients with COVID-19 and other viral pneumonia were significantly lower than those in patients with bacterial pneumonia (62.0%, 32.0%, 60.0%, all P < 0.05), paving stone sign (22.2%, 37.5%), fine mesh sign (38.9%, 31.2%), halo sign(11.1%, 25.0%), ground-glass opacity with interlobular septal thickening (30.6%, 37.5%), bilateral patchy pattern/rope shadow (80.6%, 50.0%) etc. were significantly higher than those of bacterial pneumonia (2.0%, 4.0%, 2.0%, 0%, 22.0%, all P < 0.05). The incidence of local patchy shadow in patients with COVID-19 was only 8.3%, significantly lower than that in patients with other viral pneumonia and bacterial pneumonia (8.3% vs. 68.8%, 50.0%, P < 0.05). There was no significant difference in the incidence of peripheral vascular shadow thickening in patients with COVID-19, other viral pneumonia and bacterial pneumonia (27.8%, 12.5%, 30.0%, P > 0.05). Conclusions:The probability of ground-glass opacity, paving stone and grid shadow in chest CT of patients with COVID-19 was significantly higher than those of bacterial pneumonia, and it was more common in the lower lungs and lateral dorsal segment. In other patients with viral pneumonia, ground-glass opacity was distributed in both upper and lower lungs. Bacterial pneumonia is usually characterized by single lung consolidation, distributed in lobules or large lobes and accompanied by pleural effusion.
RESUMEN
@#Objective To compare the clinical effects of coronary artery bypass grafting (CABG) via the left anterior small thoracotomy (LAST) versus lower-end sternal splitting (LESS) approach in the treatment of coronary heart disease. Methods The patients who underwent LAST CABG in Tianjin Chest Hospital from October 2015 to December 2020 were allocated to an observation group (LAST group), and the patients who underwent LESS CABG at the same period were allocated to a LESS group. Propensity score matching method was applied with a ratio of 1∶1. The baseline data, perioperative data and grafts data were compared between the two groups after matching. Results Before matching, there were 110 patients in the LAST group, and 206 patients in the LESS group. After matching, there were 110 patients in each group. In the LAST group, there were 83 males and 27 females with an average age of 60.6±8.3 years. In the LESS group, there were 80 males and 30 females with an average age of 61.0±9.6 years. There was no statistical difference in baseline data between the two groups after matching (P>0.05). The hospital stay time (t=2.255, P=0.025) and ventilator using time (t=−2.229, P=0.027) in the LAST group were significantly shorter than those in the LESS group. There were no statistical differences between the two groups in the postoperative hospital stay time, ICU stay time, postoperative left ventricular ejection fraction, postoperative left ventricular end-diastolic diameter, average number of grafts, secondary intubation, secondary thoracotomy, postoperative wound infection, sternal complications, postoperative atrial fibrillation, postoperative pulmonary infection or main adverse cardiovascular and cerebrovascular events (P>0.05). There was no statistical difference in the distribution of target vessels in the anterior descending branch, diagonal branch or posterior descending branch between the two groups (P>0.05). The grafts of the LAST group were significantly more than those of the LESS group in the area of obtuse marginal branch and posterior ventricular branch, and the grafts of the LESS group were significantly more than those of the LAST group in the area of right coronary artery (P<0.05). Post-operative computerized tomography angiography indicated that 1 patient in the LAST group had obtuse marginal branch vein bridge vessel occlusion, and the bridge vessels in the other patients were unobstructed. Conclusion Minimally invasive CABG via both LAST and LESS approaches is safe and effective. LAST approach can achieve complete revascularization for multi-vessel lesions, and it is safe and reliable, with the advantages of less trauma and aesthetic appearance. However, it requires a certain learning curve of surgical techniques and certain surgical indications.
RESUMEN
In contrast to the well-established genomic 5-methylcytosine (5mC), the existence of N6-methyladenine (6 mA) in eukaryotic genomes was discovered only recently. Initial studies found that it was actively regulated in cancer cells, suggesting its involvement in the process of carcinogenesis. However, the contribution of 6 mA in tongue squamous cell carcinoma (TSCC) still remains uncharacterized. In this study, a pan-cancer type analysis was first performed, which revealed enhanced 6 mA metabolism in diverse cancer types. The study was then focused on the regulation of 6 mA metabolism, as well as its effects on TSCC cells. To these aspects, genome 6 mA level was found greatly increased in TSCC tissues and cultured cells. By knocking down 6 mA methylases N6AMT1 and METTL4, the level of genomic 6 mA was decreased in TSCC cells. This led to suppressed colony formation and cell migration. By contrast, knockdown of 6 mA demethylase ALKBH1 resulted in an increased 6 mA level, enhanced colony formation, and cell migration. Further study suggested that regulation of the NF-κB pathway might contribute to the enhanced migration of TSCC cells. Therefore, in the case of TSCC, we have shown that genomic 6 mA modification is involved in the proliferation and migration of cancer cells.

Vitamin D plays an important role in mineral and bone homeostasis, immune responses, cardiovascular function and keratinocyte proliferation and differentiation. Vitamin D performs most of its functions by binding to vitamin D receptors (VDR), which interact with other intracellular signaling pathways to regulate bone metabolism, inflammation, immunity, cell cycle progression and apoptosis. Autophagy is a basic stress response in yeast, plants and mammals, and plays a critical role in maintaining optimal functional states at the level of cells and organs. Vitamin D/VDR plays an anti-infection role via inducing and regulating autophagy.

The cholinergic anti-inflammatory pathway (CAP) is a neuro-immunomodulatory pathway,in which acetylcholine (ACh) released by the interaction of vagal nerves with α7 nicotinic acetylcholine receptor (α7nAChR),which prevents the synthesis and release of pro-inflammatory cytokines and ultimately regulates the local or systemic inflammatory response in a feedback manner. It has been shown that there are many possible effective treatments for sepsis, including vagus nerve stimulation by physical therapy, drugs such as acetylcholine receptor agonist and ultrasound therapy.

Intensive care unit acquired muscle weakness (ICU-AW) is a neuromuscular complication secondary to severe illness. The essence for this disease is skeletal muscle dysfunction. With the development of medical technology, the survival rate for severe patients has been significantly improved. The long term complications for the severe patients with ICU-AW are getting more and more common, and they seriously affect the quality of life and prognosis of patients. However, the current treatment is ineffective. Establishment of ICU-AW animal model is an important way to study the pathogenesis and intervention targets for this disease. There are many risk factors for this disease, and the principles for ICU-AW animal models are not the same at home and abroad, and the methods of preparation are different. The choice of a reasonable animal model is important for the reliability of the results.

RESUMEN
Gamma band oscillation (GBO) and sensory gating (SG) are associated with many cognitive functions. Ketamine induces deficits of GBO and SG in the prefrontal cortex (PFC). However, the time-courses of the effects of different doses of ketamine on GBO power and SG are poorly understood. Studies have indicated that GBO power and SG have a common substrate for their generation and abnormalities. In this study, we found that (1) ketamine administration increased GBO power in the PFC in rats differently in the low- and high-dose groups; (2) auditory SG was significantly lower than baseline in the 30 mg/kg and 60 mg/kg groups, but not in the 15 mg/kg and 120 mg/kg groups; and (3) changes in SG and basal GBO power were significantly correlated in awake rats. These results indicate a relationship between mechanisms underlying auditory SG and GBO power.

Autophagy is a degradative process of eukaryotic cell, which plays a vital role in human health. Autophagy imbalance is associated with many diseases. It has been reported that vitamin D can regulate the autophagy in different levels, including induction, nucleation, as well as elongation to maturation and degradation, which affects the occurrence and development of the disease. However, its action mechanism has not been systematically elaborated, and a deeper understanding of the mechanism of vitamin D-regulated autophagy is helpful to guide the diagnosis and treatment of related diseases. The review described the mechanism of vitamin D affecting autophagy to provide theoretical basis for guiding basic and clinical research.

Objective To investigate the effect of dexmedetomidine (DEX) on inflammatory mediators in different periods of sepsis and its impact on survival rate of rats with sepsis.Methods Ninety male Wistar rats were randomly divided into three groups:control group (group C),sepsis model group (group S),and DEX treatment group (group D).Lipopolysaccharide (LPS) was injected to the vein to reproduce a classic sepsis model,while in control group,equivalent volume of NS was used instead.Different treatments were given to the corresponding groups,and then venous blood was taken at given intervals.Behavioral changes and mortality rate of rats within 48 hours after experiment were recorded.The levels of the early inflammatory mediators such as tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and the late inflammatory mediators such as high-mobility group boxl protein (HMGB1) in blood serum were detected by ELISA.Results Among three groups,there were significant differences in mortality rate of rats,the serum level of TNF-αt,IL-6 and HMGB1 (all P < 0.05).Conclusion DEX has a certain anti-inflammatory effects on early and late stages of sepsis in rats with sepsis,and can also reduce the mortality rate.
RESUMEN
OBJECTIVE@#To explore the effect of dexmedetomidine (DEX) on high-mobility group box 1 protein (HMGB1) in the serum and spleen in rats with sepsis and the underlying mechanisms. @*METHODS@#A total of 100 male Wistar rats were randomly divided into five groups: a control group, a sepsis group, a DEX group, an α-bungarotoxin- tetramethylrhodamine (α-BGT) plus DEX group and an α-BGT group (n=20 in each group). In the control group, same volume of normal saline (NS) was administrated, while lipopolysaccharide (LPS) was injected to the vein to develop a classic sepsis model. At the 48th h after LPS injection, the rats were sacrificed, and the blood and spleen were collected. The content of tumor necrosis factor-α (TNF-α) and HMGB1 in blood serum were detected by enzyme-linked immuno sorbent assay (ELISA), and the HMGB1 in the spleen was examined by Western blot. @*RESULTS@#Among the 5 groups, there were statistical significance in the mortality, the serum level of TNF-α and HMGB1, and the content of secreting type of HMGB1 in spleen (all P<0.05), and the serum level of HMGB1 was positively correlated with the content of secreting type of HMGB1 (r=0.863, P<0.05). @*CONCLUSION@#DEX exert late anti-inflammatory effects in the serum and spleen in rats with sepsis, which is related to the activation of the cholinergic anti-inflammatory pathway.

ObjectiveTo investigate the mechanism of anti-inflammatory effect of diallyl sulfide (DAS) in protection against acute lung injury (ALI) in rats with paraquat poisoning.Methods Eighty male Wistar rats were randomly divided into four groups, namely: control group, model group, dexamethasone (DXM) treatment group, and DAS treatment group, with 20 rats in each group. The model of paraquat poisoning was reproduced by single does of 70 mg/kg given by gavage, while the same volume of normal saline (NS) was given in same manner in control group. 100 mg/kg of DAS, the same volume of NS, or 1 mg/kg DXM injection were given respectively in DAS treatment group, model group, or DXM treatment group intraperitoneally after exposure to paraquat, once a day for 14 days. Five rats in each group were sacrificed at 1, 3, 7, 14 days, respectively. The inferior lobe of right lung was harvested, and the degree of lung injury was observed with hematoxylin and eosin (HE) staining under optical microscope; the upper lobe of right lung was used to determine the lung wet/dry weight (W/D) ratio and for evaluation of the degree of pulmonary edema. The expression of nuclear factor -κB (NF-κB) in the middle lobe of right lung was assessed with immunohistochemistry. The expression of tumor necrosis factor -α (TNF-α) mRNA in the left lung was determined with the reverse transcription-polymerase chain reaction (RT-PCR).Results① The pulmonary structure in control group was found to be intact. However, in the model group there were progressive pathological changes in lung, including marked edema and thickening of alveolar walls, collapse of alveoli, infiltration of inflammatory cells, alveolar wall, and obvious bleeding in the local lung tissue, and formation of transparent membrane in alveolar space. Less infiltration of inflammatory cells and no obvious destruction were found in alveolar structure in the DAS and DXM treatment groups.② Lung W/D ratio: lung W/D ratio of model group was apparently higher than that in control group at every time point, and peaking on the 3rd day (6.15±0.54 vs. 4.15±2.10,P< 0.05), and the ratio of lung W/D of DAS and DXM treatment groups was obviously lower than that in model group at every time point, especially on the 3rd day (3.99±1.26, 4.30±0.70 vs. 6.15±0.54, bothP< 0.05), but there was no significant difference between DAS and DXM treatment groups in this regard.③ The immunocytochemistry analysis revealed minimal NF-κBp65 expression in the cell nuclei of the control group, while extensive NF-κBp65 expression was found in model group. Minimal NF-κBp65 positive expression in the cytoplasm and even less positive expression in the nucleus was found in the DAS and DXM treatment groups, and integralA value was significantly lower in the DAS and DXM treatment groups than that of the model group, especially on the 3rd day [(17.98±0.06)×107, (18.53±0.04)×107 vs. (28.85±0.61)×107, bothP< 0.01], but there was no significant difference between DAS and DXM treatment groups.④ It was shown by RT-PCR that the expression of TNF-α mRNA in lung tissue of the model group was significantly higher than that in the control group on the 3rd day (gray value: 3.63±0.62 vs. 0.51±0.13, P< 0.05). The expression of TNF-α mRNA in lung tissue was significantly decreased in DAS and DXM treatment groups compared with model group (gray value: 2.49±0.57, 2.02±0.26 vs. 3.63±0.62, bothP< 0.05), but there was no significant difference between DAS and DXM treated groups.ConclusionTreatment with an intraperitoneally injection of DAS is capable of attenuate the extent of PQ-induced ALI in rats by alleviating pulmonary edema, inhibiting the expression of NF-κB and TNF-α in lung tissue, and ameliorating pathological changes in lung tissue.
