RESUMO
OBJECTIVES@#To study the application value of transport ventilator in the inter-hospital transport of critically ill children.@*METHODS@#The critically ill children in Hunan Children's Hospital who were transported with or without a transport ventilator were included as the observation group (from January 2019 to January 2020; n=122) and the control group (from January 2018 to January 2019; n=120), respectively. The two groups were compared in terms of general data, the changes in heart rate, respiratory rate, and blood oxygen saturation during transport, the incidence rates of adverse events, and outcomes.@*RESULTS@#There were no significant differences between the two groups in sex, age, oxygenation index, pediatric critical illness score, course of disease, primary disease, heart rate, respiratory rate, and transcutaneous oxygen saturation before transport (P>0.05). During transport, there were no significant differences between the two groups in the changes in heart rate, respiratory rate, and transcutaneous oxygen saturation (P>0.05). The incidence rates of tracheal catheter detachment, indwelling needle detachment, and sudden cardiac arrest in the observation group were lower than those in the control group during transport, but the difference was not statistically significant (P>0.05). Compared with the control group, the observation group had significantly shorter duration of mechanical ventilation and length of stay in the pediatric intensive care unit and significantly higher transport success rate and cure/improvement rate (P<0.05).@*CONCLUSIONS@#The application of transport ventilator in the inter-hospital transport can improve the success rate of inter-hospital transport and the prognosis in critically ill children, and therefore, it holds promise for clinical application in the inter-hospital transport of critically ill children.

Objective@#In order to analyze the characteristics of the outbreak of acute respiratory tract infection in children caused by respiratory syncytial virus(RSV).@*Methods@#The field epidemiological investigations were conducted for the two outbreaks in kindergartens in Hangzhou. Data were analyzed by descriptive method. Samples with positive respiratory syncytial virus nucleic acid were sequenced using PCR.@*Results@#The two outbreaks occurred in kindergartens. There were 21 cases in kindergarten A, lasting 11 days, and 43 cases in kindergarten B, lasting 33 days. The epidemic curve showed a proliferation pattern. The cases were concentrated in nurseries and K1 classes, primarily among children aged 2-4 years. The most common symptoms were fever and cough, mainly upper respiratory tract infection, and no severe cases were found. Upper respiratory tract samples were collected and detected as positive for RSV. Four samples were sequenced and identified as subgroup B.@*Conclusion@#During the outbreak of acute respiratory infection in kindergartens, respiratory syncytial virus should be given primary consideration in the process of identification of the outbreak caused by other respiratory infections, and strictly control measures should be taken to reduce the long term impact of the epidemic.
RESUMO
Objective:To investigate the therapeutic mechanism of high-frequency repetitive transcranial magnetic stimulation (rTMS) in treating mild amnestic cognitive impairment (aMCI).Methods:Twenty-five patients with aMCI were randomly divided into an observation group of 13 and a control group of 12. The observation group was given 10-Hz rTMS over the left dorsolateral prefrontal cortex at 80% of the motor threshold-400 pulses a day, 5 times a week for 4 consecutive weeks. The control group received sham stimulation on the same schedule. Before and after the experiment, both groups were evaluated using the Montreal cognitive assessment (MoCA) and received fMRI scans.Results:After the intervention, the average MoCA score of the observation group had improved significantly more compared with that of the control group and compared with before the intervention. According to the fMRI results, regional homogeneity in the right middle frontal gyrus of the observation group had increased significantly, while that of the control group both there and in the left precuneus had decreased significantly.Conclusions:High-frequency rTMS can effectively improve the cognitive function of patients with aMCI and synchronize neuron activity in cognition-related brain regions.
RESUMO
BACKGROUND: Glial cell line derived neurotrophic factor (GDNF) plays an important role in inducing the differentiation of bone marrow mesenchymal stem cells (BMSCs) in vitro and promoting the regeneration of neuron axons. OBJECTIVE: To observe BMSCs differentiation induced by over-expression of GDNF gene, detect synaptic function of cells and expression of Wnt signaling pathway components after differentiation, and preliminarily explore the mechanism of BMSCs differentiation into mature neurons. METHODS: Rat BMSCs were isolated and cultured, and further divided into recombinant adenovirus-containing GDNF gene transfection group (Ad-GDNF-BMSCs), adenovirus transfection control group (Ad-BMSCs), and untransfected control group. The relative expression of GDNF gene in BMSCs of each group was detected by Q-PCR, and the expression of β-catenin, cyclin D1, NeuN and MAP-2 was detected by immunofluorescence technology in each group. High K+ stimulation induced cell depolarization response after differentiation, and FM4-64 marks synaptic vesicle activity of differentiated cells. RESULTS AND CONCLUSION: (1) The adenovirus-transfected gene had no significant negative effect on the proliferation of BMSCs. BMSCs could express endogenous GDNF gene continuously and at high levels. (2) Under the induction of GDNF gene, BMSCs could express neuron-specific protein NeuN after 3 days cultivation in vitro. The expression of β-catenin protein also could be detected in the cytoplasm of cells. After 7 days cultivation in vitro culture, BMSCs expressed the mature neuronal marker protein MAP-2, and the cell body contracted significantly. Neuron axon-like structures appeared around the cell body. Moreover, β-catenin and cyclin D1 were respectively detected in the cell cytoplasm and the nucleus, while the expression levels of NeuN, MAP-2, β-catenin, and cyclin D1 were not observed in Ad-BMSCs and untransfected control groups, and the cells remained spindle-shaped. (3) After 11 days of in vitro culture, the cells in the Ad-GDNF-BMSCs group showed typical neuronal processes or axons and connected to each other into a network structure, which could be labeled with FM4-64 to show red fluorescence, and induced by high K+ stimulation to induce action potentials in the cells. Synaptic vesicle activity in posterior axons showed FM4-64 red fluorescence gradually decaying. Under the same conditions, cells in the Ad-GDNF-BMSCs group and untransfected control group did not present FM4-64 fluorescently labeled synaptic vesicle activity. (4) Continuous GDNF induction can promote BMSCs differentiated into mature neurons with synaptic cycle function, and may be carried out through the classic Wnt/β-catenin signaling pathway.
RESUMO
Purpose To analyze the expression and prognostic value of metastasis-associated protein 2 (MTA2) in epithelial ovarian carcinoma. Methods The expression of MTA2 protein was examined in 91 paraffin-embedded specimens by immunohistochemical SP method, and in fresh specimens by Western blot, and then combined with follow-up data for prognosis analysis. Results There was an increasing tendency in positive rate of MTA 2 expression from benign ovarian cysts (17.5％) to epithelial ovarian cancers (78.43％), and there were significant difference (χ2=33.328, P<0.001). The expression of the MTA2 was significantly correlated to FIGO stage and lymph node metastasis (both P<0.05). The relative expression of MTA2 in benign ovarian cysts and epithelial ovarian cancers was 0.58±0.05, and 1.22±0.10, respectively, and the difference was statistically significant (t=-22.274, P<0.001). The survival curve of patients with MTA2 (+) differed from the survival curve of patients with MTA2 (-) and the difference was statistically significant (χ2=10.203, P<0.05). The multiple factor analysis revealed that the expression of MTA2, FIGO stage and lymph node metastasis were independent prognostic factors for clinical outcome of epithelial ovarian cancer. Conclusion MTA2 may be involved in the progression and metastasis of epithelial ovarian cancer as an oncogene. Overexpression of the marker indicates poor prognosis of patients.
RESUMO
Mitochondrion is a semi-autonomous organelle, important for cell energy metabolism, apoptosis, the production of reactive oxygen species (ROS), and Ca homeostasis. Mitochondrial DNA (mtDNA) mutation is one of the primary factors in mitochondrial disorders. Though much progress has been made, there remain many difficulties in constructing cell models for mitochondrial diseases. This seriously restricts studies related to targeted drug discovery and the mechanism and therapy for such diseases. Here we summarize the characteristics of patient-specific immortalized lymphoblastoid cells, fibroblastoid cells, cytoplasmic hybrid (cybrid) cell lines, and induced pluripotent stem cells (iPSCs)-derived differentiation cells in the study of mitochondrial disorders, as well as offering discussion of roles and advances of these cell models, particularly in the screening of drugs.
RESUMO
Objective To investigate the relationship between angiotensin converting enzyme(ACE) gene polymorphism and carotid plaque composition,vessel wall morphology,and clinical symptoms based on vessel wall magnetic resonance imaging. Methods Totally 75 hypertensive patients(75 internal carotid artery plaques) with maximum plaque thickness≥1.5 mm,according to the ACE insertion(I) or deletion(D) gene polymorphism,were divided into ACE 2 genotype group(n=37) and ACE ID/DD genotype group(n=38). The influences of plaque composition,vessel wall morphology,clinical symptoms,and use of ACE inhibitor or angiotensin receptor blocker(ACEI/ARB) on vessel wall morphology were analyzed. Results Compared with ACE 2 genotype group,the ACE ID/DD genotype group had significantly higher incidence of ischemic stroke(Χ=3.921,P=0.048). The plaque composition and vessel wall morphology showed no significant difference between these two groups. Inside ACE ID/DD genotype group,the carotid remodeling index was significantly lower in users of ACEI/ARB than non-users of ACEI/ARB(1.85±0.60 vs. 2.48±0.40;t=3.854,P=0.001).Conclusion In primary hypertension,ACE ID/DD genotype may be associated with carotid atherosclerotic plaque.

RESUMO
Objective To investigate the use of noradrenaline under different monitoring methods in renal transplantation and its clinical significance in prognosis. Methods 40 patients under the surgery of renal allograft were randomly divided into two groups (20 patients each): Flotrac-vigileo group (E) and the standard monitoring group (N), then we recorded MAP (mean arterial pressure), CVP (central venous pressure) and HR (heart rate) value divided by 5 periods: after induction of general anesthesia (T1), before operation (T2), external iliac vein occlusion (T3), external iliac vein opening (T4) and the end of operation (T5).Meanwhile, intraoperative norepinephrine dosage, intake and output volumnand renal function indicators during postoperative and after three days were also studies. Length of hospital stay were also compared in this essay.Results The amount of norepinephrine in group E during operation was significantly lower than that in group N (P＜0.05). The urine volume in group E during operation was significantly higher than that in group N (P＜0.05). There was no significant difference between the two groups in the amount of transfusion, blood loss and the indexes of kidney function. Conclusions Hemodynamics monitored by peripheral cardiac output significantly reduced the amount of norepinephrine used in renal transplantation, also in the risk of renal damage. Yet it increased the amount of intraoperative urine output, which provided more accurate and personalized management of intraoperative vasoactive drugs.

RESUMO
<p><b>OBJECTIVE</b>To study the effects of intrauterine growth restriction (IUGR) and high-fat diet on the growth, lipid metabolism, and related hepatic genes in rat offspring.</p><p><b>METHODS</b>The rat model of IUGR was established by food restriction during the entire pregnancy. After weaning, 32 normal rats and 24 offspring rats with IUGR were randomly allocated to standard diet group or high-fat diet group. At the age of 10 weeks, fasting plasma glucose and blood lipid were examined. Additionally, pathological sections for hepatic tissues were observed, and the transcriptional levels of related hepatic genes were measured.</p><p><b>RESULTS</b>At the age of 10 weeks, there was a significant difference in body weight between IUGR rats and normal rats on standard diets, but no significant difference in body weight was observed between the two groups on high-fat diets. Compared with the normal rats, IUGR rats showed increased energy intake and increased levels of fasting plasma glucose, total cholesterol, and triglyceride on both standard and high-fat diets. High-fat diets reduced the concentration of serum triglyceride in both normal rats and IUGR rats. IUGR and high-fat diets aggravated the fat accumulation in the liver. Two-factor analysis of variance showed that at the age of 10 weeks, the expression of genes related to lipid metabolism in the liver, PGC-1α, CPT-1, SREBF-2, HMGR, LDLR and SREBF-1, differed significantly between IUGR and normal rats. Compared with standard diets, high-fat diets increased the expression of PPARα, SREBF-1, SREBF-2, ABCG5, and CYP7A1 in both normal rats and IUGR rats. IUGR and high-fat diets had an interactive effect on LDLR expression.</p><p><b>CONCLUSIONS</b>Hyperlipidemia and fat accumulation in the liver observed in IUGR rats may be related to increased appetite and regulation disorder in genes related to fatty acid oxidation at the transcriptional level. High-fat diets may aggravate fat accumulation in the liver in rats, which may be related to increased expression of genes related to regulation of fatty acid synthesis at the transcriptional level and reduction in secretion of triglyceride.</p>

RESUMO
The expression profile in the mouse hepatitis B virus X (HBx)-transfected model was investigated in order to lay a foundation for further study on the implication of cytokines expression in hepatitis B virus (HBV) infection. Hydrodynamic injection method via the tail vein was used to establish the animal HBx-transfected model. By using microassay, the differential expression of gene in each group was analyzed, which was further confirmed by using real-time PCR and semi-quantitative PCR. Most of chemokine genes such as Ccl2, Ccl5, Ccl9, MIG and IP-10 were up-regulated in the HBx-transfected mouse model versus the control mice, which was coincided with the microarray results. Western blotting and immunohistochemistry were applied to detect the expression of MIG and IP-10 in the liver tissues. Simultaneously, ELISA was adopted to measure the content of IFN-γ in the liver tissues. DNA microassay revealed that the expression of 611 genes changed in HBx-transfected mice as compared with that in pCMV-tag2B-transfected mice, and most of the screened chemokines were up-regulated (including MIG and IP-10). Additionally, IFN-γ protein levels were increased by 20.7% (P<0.05) in pCMV-tag2B-HBx-transfected mice as compared with the untreated mice. IFN-γ protein levels were reduced by 53.9% (P<0.05) in pCMV-tag2B-transfected mice as compared with the untreated mice, which was consistent with the up-regulation of MIG and IP-10. It was suggested HBx transfection could induce the expression of MIG and IP-10 in the liver tissues, which might play the roles in HBV-related liver immunity and cytokines-mediated antiviral effect.
