Cellular and molecular mechanisms of Notch signal in pulmonary microvascular endothelial cells after acute lung injury

Abstract This study focused on the effect and mechanism of Notch signal on pulmonary microvascular endothelial cells (PMVECs) following acute lung injury. PMVECs were cultured in vitro and randomly divided into eight groups. Grouping was based on whether cells were co-cultured with T cells (splenic CD4+T cells were isolated using MACS microbeads) and the level of Notch expression: Normal group and Normal+T cells group, Model group and Model+T cells group, Notch low-expression group and Notch low-expression+T cells group, and Notch overexpression group and Notch overexpression+T cells group. Except for the Normal group and Normal+T cells group, all other groups were treated with 500 μL lipopolysaccharide (1 μg/mL). The expression of VE-cadherin and Zo-1 protein in the Model group (with or without T cells) was lower than that in the normal group (with or without T cells), their expression in the Notch low-expression group (with or without T cells) was significantly increased, and their expression in the Notch overexpression group (with or without T cells) was significantly decreased. Compared with the normal+T cells group, the number of Treg cells in the Notch low-expression+T cells group decreased significantly (P<0.01). The number of Th17 cells in the Notch overexpression+T cells group was higher than that in the Model+T cells group (P<0.01), while the number of Treg cells decreased (P<0.01). Our results demonstrated that activated Notch signal can down-regulate the expression of the tight junction proteins VE-Cadherin and Zo-1 in PMVECs and affect Th17/Treg immune imbalance. Autophagy was discovered to be involved in this process.

Molecular mechanism of ligustilide attenuating OGD/R injury in PC12 cells by inhibiting ferroptosis / 中国中药杂志

The aim of this study is to explore the mechanism of ligustilide, the main active constituent of essential oils of traditional Chinese medicine Angelicae Sinensis Radix, on alleviating oxygen-glucose deprivation/reperfusion(OGD/R) injury in PC12 cells from the perspective of ferroptosis. OGD/R was induced in vitro, and 12 h after ligustilide addition during reperfusion, cell viability was detected by cell counting kit-8(CCK-8) assay. DCFH-DA staining was used to detect the level of intracellular reactive oxygen species(ROS). Western blot was employed to detect the expression of ferroptosis-related proteins, glutathione peroxidase 4(GPX4), transferrin receptor 1(TFR1), and solute carrier family 7 member 11(SLC7A11), and ferritinophagy-related proteins, nuclear receptor coactivator 4(NCOA4), ferritin heavy chain 1(FTH1), and microtubule-associated protein 1 light chain 3(LC3). The fluorescence intensity of LC3 protein was analyzed by immunofluorescence staining. The content of glutathione(GSH), malondialdehyde(MDA), and Fe was detected by chemiluminescent immunoassay. The effect of ligustilide on ferroptosis was observed by overexpression of NCOA4 gene. The results showed that ligustilide increased the viability of PC12 cells damaged by OGD/R, inhibited the release of ROS, reduced the content of Fe and MDA and the expression of TFR1, NCOA4, and LC3, and improved the content of GSH and the expression of GPX4, SLC7A11, and FTH1 compared with OGD/R group. After overexpression of the key protein NCOA4 in ferritinophagy, the inhibitory effect of ligustilide on ferroptosis was partially reversed, indicating that ligustilide may alleviate OGD/R injury of PC12 cells by blocking ferritinophagy and then inhibiting ferroptosis. The mechanism by which ligustilide reduced OGD/R injury in PC12 cells is that it suppressed the ferroptosis involved in ferritinophagy.

Localization of the centre of the highest region of the triceps brachii muscle spindle abundance and its significance in muscle spasticity block / Localización del centro de la región más alta del huso del músculo tríceps braquial y su importancia en el bloqueo de la espasticidad muscular

SUMMARY: This study aimed to accurately localize the location and depth of the centre of the highest region of muscle spindle abundance (CHRMSA) of the triceps brachii muscle. Twenty-four adult cadavers were placed in the prone position. The curve connecting the acromion and lateral epicondyle of the humerus close to the skin was designed as the longitudinal reference line (L), and the curve connecting the lateral and the medial epicondyle of the humerus was designed as the horizontal reference line (H). Sihler's staining was used to visualize the dense intramuscular nerve region of the triceps brachii muscle. The abundance of muscle spindle was calculated after hematoxylin and eosin stain. CHRMSA was labelled by barium sulphate, and spiral computed tomography scanning and three- dimensional reconstruction were performed. Using the Syngo system, the projection points of CHRMSA on the posterior and anterior arm surface (P and P' points), the position of P points projected to the L and H lines (PL and PH points), and the depth of CHRMSA were determined. The PL of the CHRMSA of the long, medial, and lateral heads of the triceps brachii muscle were located at 34.83 %, 75.63 %, and 63.93 % of the L line, respectively, and the PH was located at 63.46 %, 69.62 %, and 56.07 % of the H line, respectively. In addition, the depth was located at 34.73 %, 35.48 %, and 35.85 % of the PP' line, respectively. These percentage values are all the means. These body surface locations and depths are suggested to be the optimal blocking targets for botulinum toxin A in the treatment of triceps brachii muscle spasticity.

RESUMEN: Este estudio tuvo como objetivo localizar con precisión la ubicación y la profundidad del centro de la región más alta del huso muscular (CHRMSA) del músculo tríceps braquial. Se colocaron veinticuatro cadáveres adultos en posición prona y se designó la curva que conecta el acromion y el epicóndilo lateral del húmero cerca de la piel como la línea de referencia longitudinal (L), y la curva que conecta los epicóndilos lateral y medial del húmero fue designada como la línea de referencia horizontal (H). Se usó la tinción de Sihler para visualizar la región nerviosa intramuscular densa del músculo tríceps braquial. La abundancia de huso muscular se calculó después de la tinción con hematoxilina y eosina. CHRMSA se marcó con sulfato de bario y se realizó una tomografía computarizada espiral y una reconstrucción tridimensional. Usando el sistema Syngo, fueron determinados los puntos de proyección de CHRMSA en la superficie posterior y anterior del brazo (puntos P y P'), la posición de los puntos P pro- yectados en las líneas L y H (puntos PL y PH) y la profundidad de CHRMSA. Los PL de la CHRMSA de las cabezas larga, medial y lateral del músculo tríceps braquial se ubicaron en el 34,83 %, 75,63 % y 63,93 % de la línea L, respectivamente, y el PH se ubicó en el 63,46 %, 69,62 %, y 56,07 % de la línea H, respectivamente. La profundidad se ubicó en el 34,73 %, 35,48 % y 35,85 % de la línea PP', respectivamente. Estos valores porcentuales son todas las medias. Se sugiere que estas ubicaciones y profundidades de la superficie corporal son los objetivos de bloqueo óptimos para la toxina botulínica A en el tratamiento de la espasticidad del músculo tríceps braquial.

The value of oxygen index and base excess in predicting the outcome of neonatal acute respiratory distress syndrome

Abstract Objective This study aimed to identify the predictors and threshold of failure in neonatal acute respiratory distress syndrome. Methods Newborns with severe acute respiratory distress syndrome aged 0-28 days and gestational age ≥36 weeks were included in the study if their cases were managed with non-extra corporal membrane oxygenation treatments. Patients were divided into two groups according to whether they died before discharge. Predictors of non-extra corporal membrane oxygenation treatment failure were sought, and the threshold of predictors was calculated. Results A total of 103 patients were included in the study. A total of 77 (74.8%) survived hospitalization and were discharged, whereas 26 (25.2%) died. Receiver operating characteristic analysis of oxygen index, pH, base excess, and combinations of these indicators demonstrated the advantage of the combination of oxygen index and base excess over the others variables regarding their predictive ability. The area under the curve for the combination of oxygen index and base excess was 0.865. When the cut-off values of oxygen index and base excess were 30.0 and −7.4, respectively, the sensitivity and specificity for predicting death were 77.0% and 84.0%, respectively. The model with base excess added a net reclassification improvement of 0.090 to the model without base excess. Conclusion The combination of oxygen index and base excess can be used as a predictor of outcomes in neonates receiving non-extra corporal membrane oxygenation treatment for acute respiratory distress syndrome. In neonates with acute respiratory distress syndrome, if oxygen index >30 and base excess <−7.4, non-extra corporal membrane oxygenation therapy is likely to lead to death.

Clinical and microbiological characteristics of cryptococcosis at an university hospital in China from 2013 to 2017

ABSTRACT Background: This study aims to explore the epidemiology, clinical profile and strain characteristics of cryptococcosis from 2013 to 2017 in a major teaching hospital in China. Methods: Trends in antifungal drug susceptibility of 217 consecutive non-repetitive cryptococcal isolates collected from patients of an university hospital in China were analyzed between 2013 and 2017. Of those, 98 isolates were conserved for identification by internal transcribed spacer (ITS) sequencing and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) system. Multilocus sequence typing (MLST) was used to designate molecular types. Clinical characteristics of the 98 patients with cryptococcosis during the period of 2013-2017 were retrospectively evaluated. Results: There was a trend for gradual increase in the MIC range of fluconazole was from 2013 to 2017. The conserved 98 clinical cryptococcal isolates included 97 C. neoformans and one C. gattii, and 90 (91.8%) isolates belonged to ST5 genotype VNI. Out of the 98 patients with cryptococcosis, 28 (28.6%) were HIV-infected and 32 (32.7%) had no underlying diseases. HIV-infected patients had higher mortality than HIV-uninfected patients (28.6% vs 14.3%, p = 0.147). Conclusions: Most of the patients with cryptococcosis were not HIV-infected in this study, while patients with HIV had a higher mortality. Reduced susceptibility to fluconazole was observed among C. neoformans isolates, most of them belonged to ST5 genotype VNI having an impact on the effective dose of fluconazole.

A safe access and secure exit of left ventricle can be achieved by combining with real-time guidance of echocardiography. There are acceptable technology-related complications.

The characteristics of blood glucose fluctuations in patients with fulminant type 1 diabetes mellitus in the stable stage

ABSTRACT Objective: The aim was to characterize blood glucose fluctuations in patients with fulminant type 1 diabetes (FT1DM) at the stable stage using continuous blood glucose monitoring systems (CGMSs). Subjects and methods: Ten patients with FT1DM and 20 patients with classic type 1 diabetes mellitus (T1DM) (the control group) were monitored using CGMSs for 72 hours. Results: The CGMS data showed that the mean blood glucose (MBG), the standard deviation of the blood glucose (SDBG), the mean amplitude glycemic excursions (MAGE), the blood glucose areas and the percentages of blood glucose levels below 13.9 mmol/L were similar between the two groups. However, the percentage of blood glucose levels below 3.9 mmol/L was significantly higher in the FT1DM group compared to the T1DM group (p < 0.05). The minimum (Min) blood glucose level in the FT1DM group was significantly lower than that of the T1DM group (p < 0.05). Patients with FT1DM had severe dysfunction of the islet beta cells and alpha cells compared to patients with T1DM, as indicated by lower C-peptide values and higher glucagon/C-peptide values. Conclusion: In conclusion, patients with FT1DM at the stable stage were more prone to hypoglycemic episodes as recorded by CGMSs, and they had a greater association with severe dysfunction of both the beta and alpha islet cells compared to patients with T1DM.

Utility and Safety of Tolvaptan in Cirrhotic Patients with Hyponatremia: a Prospective Cohort Study

Abstract: Introduction and aim. Hyponatremia is common in patients with decompensated cirrhosis and is associated with increased mortality. Tolvaptan, a vasopressor V2 receptor antagonist, can increase free wáter excretion, but its efficacy and safety in cirrhotic patients remain unclear. Material and methods. We studied the usage and safety of tolvaptan in cirrhotic patients in a real-life, non-randomized, multicenter prospective cohort study. Forty-nine cirrhotic patients with hyponatremia were treated with tolvaptan 15 mg daily, and 48 patients not treated with tolvaptan in the same period served as controls. Improvement in serum sodium level was defined as an increase in serum sodium from < 125 to ≥ 125 mmol/L or from 125-134 to ≥ 135 mmol/L on day 7. Results. Twenty-three (47%) patients in the tolvaptan group and 17 (35%) in the control group had normal serum sodium on day 7 (p = 0.25). Serum sodium improved in 30 (61%) patients in the tolvaptan group and 17 (35%) patients in the control group (p = 0.011). Adverse events occurred in 46-47% of patients in both groups, and tolvaptan was not associated with worsened liver function. No patient with normal serum sodium on day 7 died within 30 days of treatment, whereas 16% of those with persistent hyponatremia died (p = 0.0019). Conclusion. In conclusion, short-term tolvaptan treatment is safe and can improve serum sodium level in cirrhotic patients with hyponatremia. Normalization of serum sodium level is associated with better survival.

The Cross-talk between ROS and p38MAPKα in the Ex Vivo Expanded Human Umbilical Cord Blood CD133+ Cells / 华中科技大学学报（医学）（英德文版）

This study investigated the correlation between and compared the effects of reactive oxygen species (ROS) and p38 mitogen-activated protein kinase a (p38MAPKα) in the ex vivo expanded umbilical cord blood (hUCB) CD133+ cells.hUCB CD133+ cells were cultured in the hematopoietic stem cells (HSCs) culture medium with N-acetylcysteine (NAC,an anti-oxidant),p38MAPKα-specific inhibitor (SB203580) or their combination.The levels of ROS and expression of phosphorylated p38MAPKα (p-p38) in CD133+ cells were flow cytometrically detected.The efficacy of ex vivo expansion was evaluated by the density of CD 133+ cell sub-group colony-forming cells (CFC) and cobblestone area-forming cells (CAFC) assay.Our results showed decreased ROS levels in NAC,SB203580,and their combination treatment groups were almost 37％,48％,and 85％,respectively.Furthermore,SB203580 abrogated the activation of p38MAPKα more obviously than NAC.Moreover,the CD133+ cells in SB203580 treatment group had a 21.93±1.36-fold increase,and 14.50±1.19-fold increase in NAC treatment group,but only 10.13±0.57-fold increase in control group.In addition,SB203580 treatment led a higher level increase in the number of CFU and CAFC than NAC did.These findings suggested that,in expanded CD133+ cells,ROS activates p38MAPKα,which,in turn,induces ROS production,and p38MAPKα might be the most suitable regulator in ROS- p38MAPKα pathway for the promotion ofHSCs ex vivo expansion.

Optimization in agrobacterium-mediated transformation of anthurium andraeanum using GFP as a reporter

Although Agrobacterium-mediated transformation protocols for many economically important plant species have been well established, protocol for a number of flowering plants including Anthurium andraeanum remains challenging. In this study, we report success in generating transgenic Anthurium andraeanum cv Arizona using Agrobacterium GV3101 strain harboring a binary vector carrying gfp as a reporter gene. The possibility of facilitating the screening process for transgenic plants expressing functional proteins using gfp marker was explored. In order to realize high transformation efficiency, different explant sources including undifferentiated callus pieces and petioles were compared for their regeneration efficiency and susceptibility to Agrobacterium-mediated transformation. We also optimized the concentration of AS added to co-cultivation media. Genomic PCR revealed that 11 of the 22 resistant plantlets regenerated on selective medium were successfully transformed. Green fluorescence was observed using a fluorescence microscope in 7 of the 11 PCR-positive plants, indicating GFP was expressed stably in the transformed Anthurium andraeanum. The highest transformation efficiency obtained in this study was 1.71 percent (percentage of explants with transgenic shoots in total explants) when callus explants were used as starting material and 125 umol l-1 AS was added during the co-cultivation process.

The retinal vasculature is a unique site where the microcirculation can be noninvasively imaged in vivo. This presents an opportunity to study otherwise inaccessible structural features of the microcirculation. Recently, a number of population-based studies have developed quantitative methods of measuring these retinal signs, and investigated how these signs relate to metabolic disorders such as diabetes, hypertension, obesity, and metabolic syndrome. These studies have reported fairly consistent associations of retinopathy lesions, arteriolar narrowing and venular dilation with these metabolic disorders, suggesting a microvascular component in either the pathogenesis or manifestation of these disorders. Further, several of these signs have been associated with future risk of cardiovascular outcomes, such as coronary heart disease and stroke, independently of traditional risk factors. This review will examine in detail the evidence linking retinal vascular signs with metabolic disorders and discuss their implications for research and clinical practice.

A vasculatura retiniana apresenta uma oportunidade única de observação não-invasiva da microcirculação e de suas estruturas in vivo. Recentemente, uma série de estudos populacionais desenvolveu métodos quantitativos de observação destes sinais retinianos e suas relações com distúrbios metabólicos, tais como diabetes, obesidade, hipertensão arterial e síndrome metabólica. Esses estudos demonstraram associações das lesões retinianas, entre elas estreitamento arteriolar e dilatação venular, com essas alterações metabólicas, sugerindo um componente microvascular na patogênese ou na manifestação destes distúrbios. Ainda, vários destes sinais foram associados com risco de doença cardiovascular, tais como doença arterial coronariana e acidente vascular cerebral independente dos fatores de risco clássicos. Esta revisão discute em detalhes as evidências entre os sinais retinianos e os distúrbios metabólicos e suas possíveis implicações na pesquisa e na prática clínica.

Expression of cyclin B_1 in human ameloblastoma / 实用口腔医学杂志

Objective:To detect the expression of cyclin B 1 in human ameloblastoma(AB). Methods:Expression of cyclin B1 was detected in 73 cases of AB (32 primary, 33 recurrent and 8 malignant cases), 19 of odontogenic keratocyst (OKC) and 7 of normal oral mucosa by streptovidin-biotin method. Results:The ratio of positive nuclear expression of cyclin B 1 in normal oral mucosa, OKC and AB was 28.6%(2/7), 36.8%(7/19) and 63.0%(46/73) respectively (P
