ABSTRACT

【Subjects】 To investigate the clinical application value of myocardial contrast echocardiography (MCE) in selecting CTO-PCI patients. MethodsFrom February 2019 to March 2020, a total of 50 patients with chronic coronary artery occlusion were consecutively selected as the research subjects. MCE and two-dimensional speck-tracking echocardiography were completed before and 12 months after interventional therapy. The primary end point was major adverse cardiovascular events. Patients were divided into groups according to the preoperative myocardial perfusion level of MCE. The improvement of left ventricular function was evaluated by two-dimensional echocardiography and left ventricular global longitudinal strain. ResultsCompared with the abnormal perfusion group, the improvement of GLS in the normal perfusion group was greater (P=0.028). The wall motion score index (WMSI) of the abnormal perfusion group before PCI was higher than that of the normal perfusion group (P=0.002). WMSI in the abnormal perfusion group was higher than that in the normal perfusion group one year after PCI (P<0.001). The left ventricular GLS(P=0.008).WMSI(P=0.016) and left ventricular end-diastolic volume(P=0.032) in the normal perfusion group were improved compared with those before operation; The postoperative perfusion score of patients with abnormal perfusion was significantly improved ( P=0.032). ConclusionMCE has clinical application value in optimizing the selection of CTO-PCI patients. CTO patients with different myocardial perfusion types have different benefits after PCI.

ABSTRACT

Saccharomyces boulardii is a subspecies of Saccharomyces cerevisiae and is a fungal probiotic. It can regulate the intestinal flora and enhance the barrier function of the intestinal tract. Compared with bacterial probiotics, Saccharomyces boulardii is more resistant to acid and oxidation, does not transmit genetic material with bacteria, and can be used in combination with antibiotics. Saccharomyces boulardii can function through a variety of mechanisms, and many proteases secreted by it have antitoxin effects; its own bacteria contain more polyamines, which can nourish the intestinal mucosal cells and regulate the body's metabolic balance. Besides, it can regulate multiple signal pathways to enhance intestinal immunity. Saccharomyces boulardii has been used in the treatment of ulcerative colitis (UC). The results of animal experiments and clinical studies have shown that the application of Saccharomyces boulardii can improve intestinal inflammation and enhance the therapeutic effect of mesalazine. Saccharomyces boulardii can be used as an auxiliary drug for the treatment of UC.

ABSTRACT

@# Emergencies refer to those events that cause serious social harm, including natural disasters and public health events, and require emergency response. Medical rescue team is the main emergency rescue team. While carrying out the rescue mission, they are under great pressure both physically and mentally due to the unadaptability of the rescue environment, the lack of protective materials, overwork and other reasons, often resulting in fear, tension, anxiety, pessimism, self-blame and even acute stress disorder. Without timely and effective psychological support, long-term psychological problems such as post-traumatic stress disorder will remain after the event. Comprehensive psychological support includes psychological measurement of the whole rescue process, team formation before rescue and detailed psychological support intervention training, self-relaxation during rescue, basic life and safety guarantee, drug treatment, online psychological assistance, withdrawal of stressors after rescue and lifestyle reconstruction.

ABSTRACT

Objective To investigate the mechanism of MDM2-p53 signaling pathway in the development of colorectal cancer and correlation between p53 with clinicopathological parameters, so as to further analyze the effect of p53 on prognosis. Methods The colorectal cancer tissues and the adjacent normal tissues from 86 cases of patients with colorectal cancer were collected . The expression of p53 and murine double minute 2 (MDM2) in colorectal cancer and adjacent normal tissues were detected by immunohistochemistry, Western Blot and real-time fluorescence quantitative polymerase chain reaction (RT-PCR). The prognosis of the patients was analyzed by the Kaplan-Meier survival curves. Results The protein expression and the mRNA expression of p53 and MDM2 in colorectal cancer tissues were significantly higher than that in the adjacent non-cancerous tissues (all P<0.01). A positive correlation was observed between the expression of p53 and MDM2 (r=0.785). The expression of p53 in colorectal cancer tissues were correlated well with the degree of tumor differentiation, TNM stage, lymph node metastasis and infiltration depth (all P<0.05). Survival analysis demonstrated that the mean overall survival time in p53 high expression group was (53.92±1.56) months which was significantly lower than that in p53 low expression group of (69.16±3.72) months, and the difference was statistically significant (χ2=14.78, P<0.01). Conclusions The risk and prognosis of colorectal cancer are closely related to the MDM2-p53 signaling pathway. p53 can be used as a potential target for the prognosis and treatment of colorectal cancer.

ABSTRACT

Metabolic syndrome,a kind of clinical syndrome marked by the presence of symptoms such as hyperglycemia,dyslipidemia and hypertension,has an increasing incidence and comes to be present in younger people. More importantly,prolonged maintenance of this condition can significantly increase the incidence of chronic diseases such as diabetes,cardiovascular disease and cancer.However,the formation mechanism of metabolic syndrome is very complex and has not been fully studied and revealed. Dendrobium officinale is a traditional medicine and food substance with multiple physiological functions. In recent years,D. officinale has attracted much attention from the scholars both at home and abroad due to its functions such as improving blood lipid,lowering blood pressure and regulating blood sugar. However,there is no systematic review on the current studies about D. officinale in intervening metabolic syndrome and its underlying molecular mechanism. In this paper,the biological activity of the main active components,and the research or application status of D. officinale extract in the recent years were reviewed. Then,we analyzed the digestion,absorption and the safety and toxicity of D. officinale and its active components in the body. Finally,we summarized the effects of D. officinale and its active components on metabolic syndrome in animals and human bodies,and discussed its possible molecular mechanisms at the cellular level. This paper provides solid theoretical guidance and reliable molecular basis for further research and advanced development of D. officinale and its active components,especially for its oncoming clinical application.

ABSTRACT

The soluble guanylate cyclase (s GC) is a key signal transduction enzyme in the nitric oxide (NO) -sGC-cyclic guanosine monophosphate (cGMP) pathway, which can be activated by NO and thus catalyzes the conversion of guanosine triphosphate (GTP) into the c GMP. As a second messenger, cGMP modulates the activity of downstream effectors, including the cGMP-dependent protein kinases (cGK), cGMP-dependent phosphodiesterases (PDE) and ion-gated channels, and ultimately participates in the regulation of several physiological functions, including the function of cardiovascular, gastrointestinal and central nervous systems. sGC stimulators could not only directly stimulate s GC but also synergistically act with NO to increase the sGC enzyme activity, which has shown a great potential to treat various diseases via regulating the NO-s GC-cGMP signaling pathway. Here, we give an overview of NOindependent sGC stimulators in clinical trial.

ABSTRACT

BACKGROUND:Kinesio taping is commonly used,but there is a lack of rigorous and scientific research,especially in biomechanics and exercise.OBJECTIVE:To overview the biomechanics characteristics of the ankle joint after treatment with kinesio taping,and to summarize the biomechanics difference in kinematics,kinetics,and electromyography of the ankle joint between non-kinesio and kinesio taping.METHODS:Ovid Medline,Elsevier SDOL,PubMed and CNKI databases were retrieved for the Chinese and English literatures concerning the biomechanics and exercise performance of kinesio taping published before December 2015.Subsequently,all literatures were classified according to the Oxford Centre for Evidence-based Medicine Levels of Evidence.RESULTS AND CONCLUSION:Most of literatures support the viewpoint that kinesio taping can improve ankle joint stability,increase the arch height and decrease the external load of key muscles of the ankles and feet.Some studies have suggested that during landing,kinesio taping shortened the duration of the peak of support reaction forces,reduced the flexion force,and increased the loading rate of lower extremities,thereby resulting in an increased risk for injury.Other studies have shown that kinesio taping increases the recruitment of motor units and changes the order of neuromuscular contraction,but it cannot improve the athletic performance,and even decrease the athletic performance in most cases.Whether kinesio taping improves muscular force,increases the muscular performance,and increases the power of lower extremities is under discussion;hence,in-depth studies are needed in the future.

ABSTRACT

<p><b>BACKGROUND</b>Vein graft failure (VGF) is a serious complication of coronary artery bypass graft, although the mechanism remains unclear. The study aimed to investigate the effects of microRNAs (miRNAs) on the endothelial dysfunction involved in VGF.</p><p><b>METHODS</b>Human umbilical vein endothelial cells (HUVECs) were subjected to mechanical stretch stimulation to induce endothelial dysfunction. Genome-wide transcriptome profiling was performed using the Human miRNA OneArray® V4 (PhalanxBio Inc., San Diego, USA). The miRNA-messenger RNA (mRNA) network was investigated using gene ontology and Kyoto Encyclopedia of Genes and Genomes. The miR-551b-5p mimic and inhibitor were applied to regulate miR-551b-5p expression in the HUVECs. The 5-ethynyl-2'-deoxyuridine assay, polymerase chain reaction (PCR), and Western blotting (WB) were used to assess HUVECs proliferation, mRNA expression, and protein expression, respectively. The vein graft model was established in early growth response (Egr)-1 knockout (KO) mice and wide-type (WT) C57BL/6J mice for pathological and immunohistochemical analysis. Endothelial cells isolated from the veins of WT and Egr-1 KO mice were subjected to mechanical stretch stimulation; PCR and WB were conducted to confirm the regulatory effect of Egr-1 on Intercellular adhesion molecule (Icam-1). One-way analysis of variance and independent t-test were performed for data analysis.</p><p><b>RESULTS</b>Thirty-eight miRNAs were differentially expressed in HUVECs after mechanical stretch stimulation. The bioinformatics analysis revealed that Egr-1 might be involved in VGF and was a potential target gene of miR-551b-5p. The mechanical stretch stimulation increased miR-551b-5p expression by 2.93 ± 0.08 fold (t = 3.07, P < 0.05), compared with the normal HUVECs. Transfection with the miR-551b-5p mimic or inhibitor increased expression of miR-551b-5p by 793.1 ± 171.6 fold (t = 13.84, P < 0.001) or decreased by 26.3% ± 2.4% (t = 26.39, P < 0.05) in the HUVECs, respectively. HUVECs proliferation and EGR-1 mRNA expression were significantly suppressed by inhibiting miR-551b-5p expression (P < 0.05). The lumens of the vein grafts in the Egr-1 KO mice were wider than that in the WT mice. Icam-1 expression was suppressed significantly in the Egr-1 KO vein grafts (P < 0.05).</p><p><b>CONCLUSIONS</b>Increased miR-551b-5p expression leads to endothelial dysfunction by upregulating Egr-1 expression. EGR-1 KO can improve the function of a grafted vein through suppressing Icam-1.</p>

ABSTRACT

BACKGROUND:Intervertebral disc degeneration is one of the ancient and common clinical diseases. Its complex pathogenesis affected by various factors, such as environment and genes, is stil in debate. Because of the technical limitations, there is stil no deep understanding on the molecular mechanism of intervertebral disc degeneration. However, its molecular mechanism in recent years has made considerable development. OBJECTIVE: To summarize and discuss the molecular mechanism of intervertebral disc degeneration, thereby providing the basis for the effective treatment. METHODS: CNKI and Medline databases were retrieved by the first author using computer to search relevant articles published from 2005 to 2015. The key words were “intervertebral disc degeneration, molecular mechanism, environmental factors, genes, matrix, degradation enzyme,inflammatory factor, biological environment, treatment” in Chinese and English, respectively. Mechanisms of intervertebral disc degeneration, involving genes, cel senescence and apoptosis, degradation enzyme and substrate, inflammatory cytokines, were summarized to explore the pathogenesis and possible effective treatment of intervertebral disc degeneration. RESULTS AND CONCLUSION:Totaly 153 articles were initialy retrieved and finaly 52 articles were included in result analysis according to inclusive and exclusive criteria. Unique structure and biochemical properties of the intervertebral disc are easy to cause intervertebral disc degeneration. Traditionaly, environmental factors, such as occupation and smoking, are considered as the main factors inducing intervertebral disc degeneration; however, more and more studies have shown that genes have the most important influence on intervertebral disc degeneration. Declined extracelular matrix, increased degradation enzymes, and overexpression of inflammatory factors can al destroy the entire structure of intervertebral disc, and accelerate the process of intervertebral disc degeneration. Effective treatment for intervertebral disc degeneration can be formulated depending on the deep understanding on its molecular mechanisms. Although there is a further understanding on the molecular medium of intervertebral disc degeneration, the complex biochemical environment within the intervertebral disc is stil a great chalenge to the treatment of intervertebral disc degeneration.

ABSTRACT

BACKGROUND: Cervical intervertebral foramen stenosis induced by cervical spondylosis of nerve root type usual y requires surgical treatment. The ways mainly include anterior cervical discectomy and fusion and cervical posterior intervertebral foramen decompression. Which is the best way is stil inconclusive. With innovation, anterior cervical discectomy and fusion for cervical spondylosis of nerve root type has become the mainstream in the current treatment. OBJECTIVE: To study the relationship between curative effects and intervertebral foramen-associated parameter changes in patients with cervical spondylosis of nerve root type after anterior cervical discectomy and fusion. METHODS: From March 2011 to April 2013, 132 patients with cervical spondylosis of nerve root type were treated with anterior cervical discectomy and fusion in the Changzheng Hospital Affiliated to the Second Military Medical University. Neck pain and arm pain visual analogue score, neck disability index score and imaging changes were evaluated before and after treatment. RESULTS AND CONCLUSION: 132 patients were fol owed up for 25(4-28) months. Significant differences in neck pain visual analogue scale, anterior intervertebral disc height, posterior intervertebral disc height, intervertebral foramen height, anterior and posterior diameters of the intervertebral foramen, the area of the intervertebral foramen, and the Cobb angle of the fused segment were detected in al patients before and after treatment (P < 0.05). Posterior intervertebral disc height was positively correlated with intervertebral foramen area (r=0.427, P=0.000). The increased Cobb angle of the fused segment was negatively associated with the size of intervertebral foramen (r=-0.273, P=0.003). Intervertebral foramen area was negatively associated with arm pain visual analogue score (r=-0.502, P=0.000). These results indicated that anterior cervical discectomy and fusion with an interbody fusion cage can obviously enlarge intervertebral foramen in patients with cervical spondylosis of nerve root type, and obtain good curative effect. The size of the intervertebral foramen is negatively related to the axial pain. The reconstruction of the intervertebral disc height is necessary to expand the intervertebral foramen. However, the increase of the curvature fusion segments is not helping to expand the intervertebral foramen.

ABSTRACT

OBJECTIVE: To compare the therapeutic effects between drainage blood reinfusion and temporary clamping drainage after total knee arthroplasty in patients with rheumatoid arthritis to provide a basis for clinical practice. METHODS: Data from 83 patients with rheumatoid arthritis undergoing total knee arthroplasty were retrospectively analyzed. The 83 patients were divided into a drainage blood reinfusion group (DR group, n = 45) and a temporary clamping drainage group (CD group, n = 38). In the DR group, postoperative drainage blood was used for autotransfusion. In the CD group, closed drainage was adopted, and the drainage tube was clamped for 2 h postoperatively followed by patency. The postoperative drainage amount, hemoglobin level, rate and average volume of allogeneic blood transfusion, swelling and ecchymosis of the affected knee joint, time to straight-leg raising and range of active knee flexion were compared between the two groups. RESULTS: The total drainage volume was higher in the DR group than in the CD group (P = 0.000). The average volume of postoperative allogeneic blood transfusion (P = 0.000) and the decrease in the hemoglobin level 24 h after total knee arthroplasty (P = 0.012) were lower in the DR group than in the CD group. Swelling and ecchymosis of the affected knee joint, time to straight-leg raising and the range of active knee flexion were improved in the DR group compared with the CD group (all P<0.05). CONCLUSION: Compared with temporary clamping drainage, drainage blood reinfusion after total knee arthroplasty can reduce the allogeneic blood transfusion volume and is conducive to early rehabilitation in patients with rheumatoid arthritis. .
