ABSTRACT

OBJECTIVE@#To investigate the effects of excessive endoplasmic reticulum stress on lung ischemia/reperfusion (I/R) induced myocardial injury in mice.@*METHODS@#Forty healthy SPF male C57BL/6J mice were divided into 4 groups randomly (=10):sham operation group (Sham group), lung I/R group (I/R group), endoplasmic reticulum stress (ERS) pathway agonist Tunicamycin group (TM) and ERS inhibitor 4-phenyl butyric acid group (4-PBA). The model of lung I/R injury was established by clamping the left hilum of lung for 30 min followed by 180 min of reperfusion. In sham group, only sternotomy was performed, the hilum of lung was not clamped, and the mice were mechanically ventilated for 210 min. In TM and 4-PBA groups, TM 1mg/kg and 4-PBA 400 mg/kg were injected intraperitoneally, respectively, at 30 min before establishment of the model. At 180 min of reperfusion, blood samples were collected from the orbit for determination of myocardial enzyme. The animals were then sacrificed, and hearts were removed for determination of light microscope, TUNEL, Caspase 3 enzymatic activity, real-time polymerase chain reaction and Western blot.@*RESULTS@#Compared with sham group, the cardiomyocytes had obvious damage under light microscope, and the serum creatine kinase-MB (CK-MB) and lactic dehydrogenase (LDH) activities, apoptosis index and Caspase 3 enzymatic activity were increased significantly, the expressions of p-Jun N-terminalkinase(p-JNK), Caspase 12, CCAAT/enhancer-binding protein homologous protein (CHOP) and glucose regulated protein 78(GRP78) protein and mRNA were up-regulated in I/R, TM and 4-PBA groups (<0.01). Compared with I/R group, the cardiomyocytes damage was obvious under light microscope, and the serum CK-MB and LDH activities, apoptosis index and Caspase 3 enzymatic activity were increased significantly, the expressions of p-JNK, Caspase 12, CHOP and GRP78 protein and mRNA were up-regulated in group TM; while all above changes were relieved in group 4-PBA (<0.01). Compared with TM group, the cardiomyocytes damage was relieved under light microscope, and the serum CK-MB and LDH activities, apoptosis index and Caspase 3 enzymatic activity were decreased significantly, the expressions of p-JNK, Caspase 12,CHOP and GRP78 protein and mRNA were down-regulated in group 4-PBA.@*CONCLUSIONS@#The excessive endoplasmic reticulum stress participates in myocardial injury induced by lung ischemia/reperfusion (I/R) and inhibit excessive endoplasmic reticulum stress response can relieved myocardial injury.

ABSTRACT

OBJECTIVES@#To investigate the effects of dexmedetomidine (Dex) on injury of A549 cells induced by hypoxia/reoxygenation(H/R)and the influence of C/EBP homologous protein (CHOP) expression.@*METHODS@#Logarithmic growth phase A549 cells(it originated from alveolar type Ⅱ epithelial cell line) were randomly divided into 4 groups (=10):normoxic control group (N), Dex group (D), hypoxia/reoxygenation group (H), hypoxia/reoxygenation + Dex group(HD). At the beginning of modeling, 1 nmol/L Dex was puted into D and HD groups. N and D groups were cultured in the normoxic incubator for 30 h. H and HD group were incubated in the anoxic cultivation for 6 h, fo llowed by normoxic culture for 24 h. Then A549 cells were observed under the inverted microscope to observe the morphological changes. Cell activity was detected by cell counting Kit-8(CCK-8) and the apoptosis index(AI) was detected by in situ end labeling (TUNEL) method. The expression of CHOP、glucose-regulated protein of molecular weight 78 kDa (Grp78)、cysteinyl aspirate-specificprotease-3 (caspase-3) protein and CHOP、Grp78 mRNA were detected by Western blot and RT-PCR.@*RESULTS@#Compared with N group, the number of adherent cells in H group decreased significantly, and cell morphology changed. The absorbance value in H group decreased obviously (<0. 01). The AI value and expression of CHOP, Grp78, caspase-3 proteins and CHOP, Grp78 mRNA were significantly increased (<0.01). Compared with H group, the cell damage in HD group was decreased, the absorbance value increased (<0.01), the number of apoptosis cells decreased relatively (<0.01), the expression of CHOP, caspase-3 protein and CHOP mRNA decreased (<0. 01).@*CONCLUSIONS@#Dex has notable effects against H/R injury, which may be related to effective inhibition of apoptosis mediated by the CHOP's signal path.

ABSTRACT

The purpose of the present study was to investigate the effect of excessive endoplasmic reticulum stress (ERS) on the brain damage in hypoxia hypercapnia induced pulmonary hypertension (HHPH) rats. Forty healthy SPF male SD rats were randomly divided into four groups (n = 10 for each): control group, hypoxia hypercapnia group, ERS pathway agonist tunicamycin (TM) group and ERS pathway inhibitor 4-phenylbutyric acid (4-PBA) group. The rats of control group lived in normal environment, while the rats of other three groups were raised for four weeks in the tank with 8.5%-11% Oand 5%-6% CO. TM (0.08 mg/kg, twice a week) and 4-PBA (80 mg/kg, daily) were respectively intraperitoneally injected into the rats of TM and 4-PBA groups, and the hypoxia hypercapnia group was given the same volume of normal saline. The mean pulmonary artery pressure and heart perfusion of the rats were determined and recorded after four-week raising. Then the brain tissue of the rats were quickly taken out for the brain water content measuring and morphological changes observing. The Caspase-3 activity and the apoptotic index of the brain cells were also determined. The protein and mRNA expressions of p-JNK, Caspase-12, CHOP and GRP78 in brain tissues were detected by Western blot and RT-PCR. The results showed that compared with the control group, the mean pulmonary artery pressure, brain water content and brain cells apoptotic index, Caspase-3 activity, the protein and mRNA levels of p-JNK, Caspase-12, CHOP and GRP78 were increased (P < 0.05), and the brain tissues of the rats were obviously damaged in the rats raised in the hypoxia hypercapnia environment; compared with hypoxia hypercapnia group, the mean pulmonary artery pressure, brain water content, brain apoptotic index and Caspase-3 activity, p-JNK, Caspase-12, CHOP, GRP78 protein and mRNA expressions in TM group were increased (P < 0.05), and the brain tissues of the rats were obviously damaged, while all above changes were relieved in 4-PBA group (P < 0.05). These results suggest that excessive ERS may participate in the brain injury induced by HHPH in rats and inhibition of excessive ERS can relieve the brain injury in the rats with HHPH.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the signal transduction mechanisms of apoptosis in renal tubular epithelial cells in diabetic rats with fluctuant high blood glucose.</p><p><b>METHODS</b>Healthy SD rats were randomly divided into 3 groups: normal control group (A), stable high blood glucose group (B) and fluctuant high blood glucose group (C). Diabetic rats were induced by intraperitoneal injection of streptozotocin (STZ, 65 mg/kg), and the fluctuant high blood glucose animal model was induced by intraperitoneal injection of ordinary insulin and glucose at different time point every day. The superoxide dismutase (SOD) activity and the content of malonaldehyde (MDA) in renal tissue homogenate were detected with colorimetry.

ABSTRACT

The aim of the present study is to investigate the effects of Panax notoginseng saponins (PNS) on pneumocyte apoptosis and apoptosis-related protein, as well as c-Jun N-terminal kinase (JNK) in lung ischemia/reperfusion (I/R) injury. Thirty Wistar rats were randomly divided into control group, I/R group and PNS group. The unilateral lung I/R model was replicated by obstruction of left lung hilus for 30 min and reperfusion for 120 min in vivo. The rats in PNS group were given intraperitoneal injection of PNS at 60 min before ischemia and 10 min before reperfusion. Some lung tissues sampled at the end of the experiment were assayed for wet/dry weight ratio (W/T). The expressions of phosphorylated JNK (p-JNK) and JNK protein were detected by Western blot. The expressions of Bcl-2, Bax and Caspase-3 protein were detected by immunocytochemistry techniques. The pneumocyte apoptotic index (AI) was detected by terminal deoxynuleotidy1 transferase mediated dUTP nick end labeling (TUNEL). The morphological and ultrastructure changes were observed under light microscope and electron microscope, and the injured alveolus rate (IAR) was counted as well. The results showed that compared to control group, I/R group showed increased expressions of p-JNK, Bcl-2, Bax and Caspase-3 protein (all P < 0.01), decreased ratio of Bcl-2/Bax (P < 0.05), and increased values of AI, W/T and IAR (all P < 0.01). Moreover, light microscope and electron microscope showed serious morphological and ultrastructure injury in I/R group. Compared to I/R group, PNS group showed markedly decreased expressions of p-JNK, Bax and Caspase-3 protein (all P < 0.01), increased expression of Bcl-2 protein and ratio of Bcl-2/Bax (both P < 0.01), and lower values of AI, W/T and IAR (all P < 0.01). Meanwhile, light morphological and ultrastructure injury was found to be alleviated in PNS group. These results suggest that PNS can protect lung tissue from I/R injury, and the mechanism may correlate with suppressing JNK signal pathway, up-regulating the ratio of Bcl-2/Bax which results in inhibition of Caspase-3 dependent apoptosis.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the intervention and mechanism of ambroxol combined with low-dose heparin on oxidative stress, TNF-alpha and IL-1beta in rabbits with acute lung injury (ALI).</p><p><b>METHODS</b>Twenty-four healthy Japanese rabbits were randomly divided into three groups: (1) Normal saline control group (NC), (2) Oleic acid injury group (OA), (3) Ambroxol + low-dose heparin therapy group (AH). After the success of ALI model, AH group was injected ambroxol + low-dose heparin, while the NC group and OA group were injected the same dose of normal saline by the same method. Arterial oxygen tension (PaO2), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) at different time points were determined. The pathological manifestation of both side lungs was observed at the end of expeiment. The activity of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), xanthine oxidase (XO) and the content of malondialdehyde (MDA) in bronchoalveolar lavage fluid (BALF) and lung tissue homogenate were tested. The apoptosis index was detected. The lung wet/dry (W/D) ratio was calculated. The pathological changes in lung tissue were observed by light microscopy, and the ultrastructural changes of lung tissue were observed by electron microscopy.</p><p><b>RESULTS</b>(1) The instructive injury induced by ALI observed under electron microscope and light microscope and W/D was decreased significantly in AH group. (2) PaO2 was improved significantly in AH group, compared with that in OA group (P < 0.01). (3) The activity of GSH-Px and SOD in AH group increased significantly (P < 0.01 or P < 0.05) but the activity of XO and the content of MDA decreased significantly (P < 0.01), compared with those in OA group. (4) Except the content of IL-1beta in serum before treatment, the content of IL-1beta and TNF-alpha in serum, BALF, lung tissue homogenate of OA group increased significantly (P < 0.01), and those were obviously improved in AH group. (5) Apoptosis index (AI) in AH group decreased significantly (P < 0.01) compared with that in OA group.</p><p><b>CONCLUSION</b>In ALI induced by OA, IL-1beta and TNF-alpha increases significantly and involved in the occurrence and development of ALI. Ambroxol combined with low-dose heparin can reduce lung cells oxidative stress to inhibit the release of IL-1beta and TNF-alpha, which play a role in the treatment of ALI.</p>
