RESUMO

OBJECTIVE To reveal the role of the basal forebrain(BF)GABAergic neurons in the regulation of isoflurane anesthesia and to elucidate the underlying neural pathways.METHODS The activity of BF GABAer-gic neurons was monitored during isoflurane anesthesia using a genetically encoded calcium indicator in Vgat-Cre mice of both sexes.The activity of BF GABAer-gic neurons was manipulated by chemogenetic and opto-genetic approaches.Sensitivity,induction time and emer-gence time of isoflurane anesthesia were estimated by righting reflex.The electroencephalogram(EEG)power and burst-suppression were monitored by EEG recording.The effects of activation of GABAergic BF-thalamic reticu-lar nucleus(TRN)pathway on isoflurane anesthesia were investigated with optogenetics.RESULTS The activity of BF GABAergic neurons was generally inhibited during isoflurane anesthesia,obviously decreased during the induction of anesthesia and gradually restored during the emergence from anesthesia.Activation of BF GABAergic neurons with chemogenetics and optogenetics promoted behavioral emergence from isoflurane anesthesia,with decreased sensitivity to isoflurane,delayed induction and accelerated emergence from isoflurane anesthesia.Optogenetic activation of BF GABAergic neurons prom-oted cortical activity during isoflurane anesthesia,with decreased EEG delta power and burst suppression ratio during 0.8%and 1.4%isoflurane anesthesia,respectively.Similar to the effects of activating BF GABAergic cell bod-ies,photostimulation of BF GABAergic terminals in the TRN also strongly promoted cortical activation and behav-ioral emergence from isoflurane anesthesia.CONCLU-SION The GABAergic neurons in the BF is a key neural substrate for general anesthesia regulation that facilitates behavioral and cortical emergence from general anesthe-sia via the BF-TRN pathway.

RESUMO

ObjectiveTo evaluate the clinical efficacy and safety of Notoginseng Radix et Rhizoma powder in treating dyslipidemia by regulating the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. MethodSixty patients with dyslipidemia (syndrome of combined phlegm and stasis) treated in the Third Affiliated Hospital of Henan University of Chinese Medicine from May 2021 to June 2022 were selected in this study and randomized into two groups according to the randomized, double-blind control principle. The control group was treated with Xuezhikang capsules + Notoginseng Radix et Rhizoma powder placebo and the observation group with Notoginseng Radix et Rhizoma powder + Xuezhikang capsules placebo for 6 weeks. The clinical efficacy, traditional Chinese Medicine (TCM) syndrome scores, and liver and kidney function indicators were evaluated at weeks 0, 3, and 6. Enzyme-linked immunosorbent assay (ELISA) was employed to determine the expression of vascular endothelial growth factor (VEGF), kinase insert domain receptor (KDR), epidermal growth factor (EGF), and epidermal growth factor receptor (EGFR) in the peripheral serum. Quantitative Real-time PCR was employed to measure the mRNA levels of KDR, EGFR, PI3K, and Akt in the mononuclear cells of the peripheral blood. ResultThe observation group (83.33%) showed the total effective rate comparable to that of the control group (89.66%) and no adverse reactions. Compared with before treatment, the patients in the observation group showed decreased TCM syndrome score and serum levels total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) and after being treated for 3 and 6 weeks (P<0.05), the level of high-density lipoprotein cholesterol (HDL-C) showed an upward trend, but the difference was not statistically significant. After treatment, the two groups showed no significant differences. Compared with that before treatment, the mRNA expression of PI3K, Akt and EGFR in peripheral blood mononuclear cell and the expression of EGF, VEGF and KDR in serum of the observation group showed a downward trend with time, in which the mRNA expression of PI3K, Akt, VEGF and KDR decreased more significantly (P<0.05),The expression levels of KDR mRNA and serum EGFR show a trend of first increasing and then decreasing.Compared with the control group after treatment, there was no statistically significant difference in mRNA expression of PI3K, Akt, EGFR, and KDR, as well as serum levels of EGF, EGFR, VEGF, and KDR between the two groups of patients at the same time point. ConclusionNotoginseng Radix et Rhizoma powder is safe and effective in correcting dyslipidemia. It may inhibit the PI3K/Akt signaling pathway by down-regulating the expression of VEGF/KDR to lower the blood lipid level.

RESUMO

As an important zoonotic pathogen, Staphylococcus aureus has led to serious mastitis and endometritis in infected dairy cows. In this study, a total of 164 strains of S. aureus were isolated from dairy cows in Xinjiang Province, China, and subjected to assays to determine drug susceptibility and biofilm (BF) formation ability. Enterotoxin-related genes were detected, and the transcription levels of genes related to BF formation were determined by using reverse transcription-quantitative polymerase chain reaction. Moreover, the pathogenicity of isolates with different BF formation abilities was determined by measuring their hemolysis activity, half lethal dose (LD₅₀) and organ bacterial load. The results showed that 86.0% of S. aureus isolates could form BF. Among them, 42.1% of the strains had weak BF formation ability, and most strains with a strong BF formation ability were ica gene carriers. The S. aureus isolates displayed multidrug resistance and their drug resistance was positively correlated with their BF formation ability. Moreover, 96.3% of the S. aureus isolates carried enterotoxin genes. Among them, the detection rates of the novel enterotoxin genes were higher than those of conventional enterotoxin genes. Furthermore, isolates with a strong BF formation ability had higher LD50 but lower hemolysis ability and organ bacterial load than those of the isolates with weak or no BF ability. However, isolates without BF ability produced more severe pathological changes than those of isolates with strong BF formation ability. These findings suggest that higher BF ability and presence of novel enterotoxin genes are important characteristics of S. aureus isolates from dairy cows in Xinjiang Province, China, and such isolates may pose potential threats to food safety.

RESUMO

BACKGROUND:There is a certain association between stem cels, microenvironment and methods for promoting blood circulation and removing stasis. OBJECTIVE:To propose a perspective of“kidney properties”of promoting blood circulation and removing stasis by elaborating the correlation and interactions of stem cels and microenvironment with methods for promoting blood circulation and removing stasis. METHODS:A computer-based search of Chinese Journal Ful-text Database, Wanfang and PubMed was performed for articles published form 2009 to 2015 addressing improving stem cel proliferation and differentiation by promoting blood circulation and removing stasis as wel as microenvironments. The keywords were “bone mesenchymal stem cels, transformation, differentiation, blood-activation and stasis-resolved method, microenvironment” in Chinese and English, respectively. Finaly, 32 literatures were reviewed. RESULTS AND CONCLUSION:Stem cels homing to the damaged tissue trigger an“environment-dependent differentiation”,that is, stem cels candifferentiate into myocardial cels, vascular endothelial cels and other injured tissues and cels under local special microenvironments. Microenvironment as an assembly for integrating dynamic, microscopic changes as wel as development of a variety of indices is of great importance for stem cel survival, proliferation and differentiation. Recipes for promoting blood circulation and removing stasis are involvedto regulate multi-steps and multi-targets during stem cel homing. Theoreticaly, this review attempts to investigate correlation among stem cels, microenvironment and methods for promoting blood circulation and removing stasis in association with previous preclinical and clinical findings. Here, we further refine the view of “kidney properties” of promoting blood circulation and removing stasis and clarify that stem cels as the material basis of “kidney properties”of promoting blood circulation and removing stasis is the main executor for promoting blood circulation and removing stasis. This paper is of a certain value for fuly revealing the scientific connotation of the theory of promoting blood circulation and removing stasis.

RESUMO

BACKGROUND:New ideas for regenerative treatment of cardiovascular disease are as fol ows:to understand the changes in al kinds of stem cel s differentiating into cardiomyocytes, to determine the physiological role of differentiated stem cel s in cardiac functional activities, to stimulate the proliferative potential of various stem cel s under certain conditions that can directly differentiate into functional cardiomyocytes, thereby replenishing deficient cardiomyocytes and effectively inhibiting excessive proliferation of fibroblasts. OBJECTIVE:To investigate the effects of panax notoginseng saponins, salidroside and astragalus effective components on the homing, proliferation and differentiation of endogenous CD105-positive bone marrow mesenchymal stem cel s of myocardial infarction rats. METHODS:Acute myocardial infarction rats were randomly divided into activating blood circulation group, tonifying qi group, activating blood circulation+tonifying qi group (combined group), model group. Normal rats served as control group. The former three groups were oral y given 80 g/L Xuesaitong soft capsules (panax notoginseng saponins as the main component), 0.5 g/mL astragalus particles and 70 g/L Nuodikang capsules (salidroside as the main component), respectively, at a dose of 1 mL/100 g, once a day, total y for 28 days. The control and model groups were given the same volume of normal saline. Expressions of CD105, CD117, vimentin, cardiac troponin T (cTnT), zinc finger transcription factor 4 (GATA-4) and Ki-67 were detected using immunohistochemical method at 1, 3, 7, 14, 28 days of drug administration. RESULTS AND CONCLUSION:(1) Compared with the control group, the expressions of CD105, CD117, cTnT, GATA-4 and Ki-67 were higher in the model group, which were increased at 1-7 days, peaked at 7 days, and then decreased. Compared with the model group, the expressions of CD105, CD117, cTnT, GATA-4 and Ki-67 were significantly higher in the activating blood circulation group, tonifying qi group and combined group, especial y in the activating blood circulating group, at different time of drug administration (P<0.05). In each group, the staining results of Ki-67 were not exactly paral el to those of CD105, CD117, cTnT and GATA-4, but their rising tendency was substantial y the same. (2) Compared with the control group, the vimentin expression in the model group was higher, which showed an increasing tend at 1-3 days, peaked at 3 days and then declined. Compared with the model group, the vimentin expression was significantly lower in the activating blood circulation group, tonifying qi group and combined group, especial y in the activating blood circulating group, at different time of drug administration (P<0.05). It suggested that the activating blood circulation group had a remarkable antifibrotic role. These findings indicate that panax notoginseng saponins, salidroside and astragalus effective components al can promote the proliferation and differentiation of bone marrow mesenchymal stem cel s to delay myocardial remodeling, but the recipe for promoting blood circulation has the most obvious outcomes.

RESUMO

Human epidermal growth factor receptor 2(Her-2),which is often over-expressed in 20%-25% of invasive breast cancer patients,is associated with an aggressive tumor phenotype and therefore,a reduced survival rate.As a widely clinically applied Her-2-targeted monoclonal antibody,herceptin,when combined with chemotherapy,significantly increases the survival time of patients without tumors.However,the majority of the cancers that initially respond positively to herceptin begin to counteract against the treatment within just 1 year.This study described several important and well-known mechanisms as well as the updates and advancement in this field.These mechanisms include over-activation of the P13K/AKT pathway,abnormal expression in the EGFR family and their ligands,the masking of the Her-2 receptor,herceptin,activation of PI3K/AKT via an alternative pathway,over-expression of Darpp-32 and t-Darpp.autophagy of tumor cells and over-expression of HSP27,and more.

Methods The ultrastructure of detrusor was studied by transmission electron microscopy in 43 cases of BPH(mean age 69.5±6.0 years)and 21 cases(mean age 65.4±7.2 years)of geriatric without bladder outlet obstruction(the controls).All the cases were performed urodynamic test. Results The IPSS(21.1±3.0 VS 7.6±1.4),maximum flow rate(7.7±1.3 ml/s VS 14.9±2.3 ml/s)and AG(44.8±9.9 VS 19.0±5.9)showed significant differences between the the BPH group and control group(P<0.01).Pdet-Qmax in the BPH group(60.1±11.0 cm H20)was higher than that in the control group(48.7±7.1 cm H2o) (P<0.05).The relative density of mitochondria in the BPH group(0.81±0.24)was lower than that in the control group(1.03±0.11)(P<0.05).The intercellular linkage in the BPH group(19.4±4.8 rim)was larger than the control group(14.1±2.0 nm)(P<0.05). Conclusions The swelling and reduction of the relative density of mitochondria could be seen in the bladder detrusor of BPH patients.The large intercellular linkage might be the reason of decrease the coordinate contractility of the blad-der detrusor.

RESUMO

Objective:To observe effects of Panax pseudo-ginseng saponins on protein expression of VEGF, bFGF in myocardium in acute myocardial infarction rats. Methods: The acute myocardial infraction (AMI) model was established in one hundred and forty Wistar rats, and the rats were randomly divided into five groups: the western medicine group mobilized by subcutaneous injection of G-CSF50?g.kg-1.d-1, sham-operated group and model group treated by subcutaneous injection of normal saline 50?g.kg-1.d-1, the Chinese medicine group mobilized by intraperitoneal injection of Xuesaitong (ingredients of Panax pseudo-ginseng saponins) 150mg.kg-1.d-1, the integrative group mobilized by subcutaneous injection of G-CSF 50?g.kg-1.d and intraperitoneal injection of Xuesaitong 150mg.kg-1.d-1. Except for the sham-operated group, each group was divided into three sub-groups by three time points of 1d, 7d and 14d. G-CSF was used once a day for 7 days. Xuesaitong was injected once a day until the rats were killed. The parameters cardiac function in rats with myocardial infarction were detection by color doppler ultrasonic diagnostic apparatus in different times,the expression of VEGF, bFGF in Marginal zone of myocardium in rats with myocardial infarction were detected by immunohistochemistry in different time. Pathological and ultrastructural changes of marginal zone in rats with acute myocardial infarction were observed by electron microscopy and light microscopy. Results:Panax pseudo-ginseng saponins can improve the level of left ventricular systolic function such as EF,FS,it can inhibit the increase of left ventricular LVDD and LVDS,it can improve expression levels of VEGF,bFGF of marginal zone in acute myocardial infarction rats. It also can reduce the damage to cell ultrastructure and promote revascularization in the site around MI area. Panax pseudo-ginseng saponins can protect the myocytes in rats with myocardial infarction. Conclusion:Panax pseudo-ginseng saponins can protect myocardium from ischemic injury in rats after AMI by way of improving expressions of VEGF and bFGF in myocardial cells and promoting angiogenesis in the infarcted of myocardium.

RESUMO

Objective:To study the anti-depression mechanism of Shugan Jiannao Tiaoyu Tablets(SJTT) and provide evidene for clinical application. Methods: Depressive rat model were established by unpredictable stress with raising alone. Model rats were randomly divided into 5 groups, each 12, then each group was administrated through intragastric perfusion daily with the rate of 1.0ml/100g according to their weight before stimulation: fluoxetine group with 0.75 mg/kg, low-dose group of SJTT with 1.8g/kg, high-dose group of SJTT with 3.6g/kg, normal group and model group with 1.0ml/100g of isotonic Na chloride. The whole course lasted for 21 days from the first day of model making to the day of death. The pathologic character of hippocampus was observed by light microscopic examination. The change of cell ultramicrostructure was observed by transmission electron microscope. The expression of C-FOS and C-JUN were detected by immunohistochemistry. Results: SJTT could reduce the neuron damage of hippocam. Compared with model group, the gray scale of immunoreaction positve cells of C-FOS and C-JUN increased in high dose group of SJTT. Conclusion:SJTT can decrease the neuron damage induced by stress in hippacam and had anti-depression effect.

RESUMO

Aim To investigate the influences on the aortal structure of rats with long-term high fat forages diet.Methods 14 SD rats were divided into two groups:the control group and the test group. The test rats were fed with high fat forages.12 weeks later, the aortas of the rats were observed with a light microscope, transmission electron microscope(TEM) and scanning electron microscope (SEM).Results In the test group, the aortic tunica intima thickening, endotheliocyte injury and monocyte adhesion were found with a light microscope; the elastic lamina being broken and the smooth muscle cells proliferated. Under TEM, the endothelial cell membrane of the aorta in the test rats was destroyed and appeared to be worm-eclipsed shape.Mitochondria exhibited swelling,vacuole degeneration and its cristae was dissolved, broken or some disappeared.Rough endoplasmic reticula (RER) expanded. The endothelial cell spaces were enlarged and the cell junctions deformed. Monocytes adhering to the endothelial cell stretched out pseudopodia and intruded into the endothelial crevice and the subendothelial layer. Some basement membranes completely sloughed following with endothelial cell. ERE and ribosomes increased in smooth muscle cells. SEM observation showed that the endothelial cells became swelling and the surface of endothelial cell was worm-eclipsed or crater shape. There were deeper crevices between endothelial cells.Conclusions Long-term high fat forages diet can induce injury of the endothelium and elastic lamina, adhesion of the monocytes and its intrusion into endothelial layer and subendothelial layer, proliferation of the subendothelial layer and smooth muscle in the aorta of rats.

RESUMO

<p><b>OBJECTIVE</b>To study the effect of retinoid kappa receptor alpha (RXRalpha) transfection plus treatment with the RXRalpha ligand, 9-cis-RA, on the proliferation and phenotype of platelet-derived growth factor (PDGF) activated hepatic stellate cells (HSCs).</p><p><b>METHODS</b>PDGF activated rat hepatic stellate cells were transfected with eukaryotic expression vector pcDNA3.1- human RXRalpha, and confirmed by Western blot. Proliferation of transfected HSC was assayed by bromodeoxyuridine (BrdU) incorporation as well as MTT, and the phenotype (alpha-smooth muscle actin, desmin) was observed by immunocytochemistry with image analysis.</p><p><b>RESULTS</b>Transfection of the RXRalpha gene and treatment with ligand 9-cis-RA of PDGF-activated HSCs extended the increased expression of RXRalpha protein for at least 168 hours. Cell proliferation and expressions of alpha- smooth muscle actin (alpha-SMA) and desmin were blocked, compared with groups of sham-transfected, PDGF-activated, no transfection, no ligand treatment, and irrelevant ligand treated HSCs.</p><p><b>CONCLUSION</b>Transfection with the RXRalpha gene followed by 9-cis-RA ligand treatment will inhibit the proliferation and reverse the phenotype of activated HSC.</p>
