Objective:To evaluate the role of deubiquitinase OTUD1 in acute lung injury in septic mice and the relationship with transforming growth factor-beta activated kinase 1(TAK1)-mitogen-activated protein kinase (MAPK) signaling pathway.Methods:Twenty male wild-type (WT) and 20 OTUD1 gene knockout (KO) C57BL/6N mice, aged 6-8 weeks, weighing 20-25 g, were divided into 4 groups ( n=10 each) using a random number table method: wild-type+ sham operation group (WT-Sham group), wild-type+ sepsis group (WT-SEP group), OTUD1-KO+ sham operation group (KO-Sham group) and OTUD1-KO+ SEP group (KO-SEP group). The acute lung injury was induced by cecal ligation and perforation (CLP) in anesthetized septic mice. Mice were sacrificed at 24 h after operation, blood samples were collected from the abdominal aorta, and lung tissues were collected. Blood gas analysis was performed using the i-STAT blood gas analyzer, PaO 2 and FiO 2 were recorded, and the oxygenation index (OI) was calculated. The morphology of lung tissues was examined with a light microscope for evaluation of lung injury, and lung injury scores were calculated. The wet to dry lung weight (W/D) ratio was measured, and the activities of MPO were measured. The concentrations of TNF-α and IL-6 in plasma were detected by enzyme-linked immunosorbent assay, and the expression of OTUD1, phosphorylated TAK1 (p-TAK1), phosphorylated p38 (p-p38), phosphorylated c-Jun amino-terminal kinase (p-JNK) and phosphorylated extracellular signal-regulated kinase (p-ERK) was detected using Western blot. Results:Compared with WT-Sham group, the PaO 2 and OI were significantly decreased, the lung injury score, W/D ratio, MPO activity, and plasma TNF-α and IL-6 concentrations were increased, and the expression of OTUD1, p-TAK1, p-p38, p-JNK and p-ERK protein in lung tissues was up-regulated in WT-SEP group ( P<0.05). Compared with WT-SEP group, the PaO 2 and OI were significantly decreased, the lung injury score, W/D ratio, MPO activity, and plasma TNF-α and IL-6 concentrations were increased, and the expression of OTUD1, p-TAK1, p-p38, p-JNK and p-ERK protein in lung tissues was up-regulated in KO-SEP group ( P<0.05). Conclusions:OTUD1 is involved in the endogenous protective mechanism against acute lung injury in septic mice, which may be related to the inhibition of TAK1-MAPK signaling pathway activation and decreased inflammatory responses.

Objective:To evaluate the role of tumor necrosis factor-alpha-induced protein-8 like-2(TIPE2) in sepsis-induced myocardial injury and the relationship with serine-threonine kinase(AKT)/glycogen synthase kinase-3β(GSK-3β)/β-catenin signaling pathway in mice.Methods:Sixteen male wild-type C57BL/6N mice and 16 TIPE2-gene knockout C57BL/6N mice, aged 6-8 weeks, with a body mass index of 20-25 g, were divided into 4 groups using a random number table method: wild-type+ sham operation group(group WT-sham), wild-type+ cecal ligation and perforation(CLP) group(group WT-CLP), TIPE2-gene knockout sham operation group(group KO-sham) and TIPE2-gene knockout CLP group(group KO-CLP), with 8 mice in each group. The model of myocardial injury induced by sepsis was developed by CLP in anesthetized animals. Blood samples from the inferior vena cava were collected at 24 h after surgery for determination of the concentrations of cardiac troponin I(cTnI) in serum by enzyme-linked immunosorbent assay. Then the mice were sacrificed and myocardial tissues were collected for determination of the pathological changes(by hematoxylin and eosin staining), expression of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and IL-6 mRNA(by quantitative polymerase chain reaction), and expression of TIPE2, phosphorylated AKT(p-AKT), phosphorylated GSK-3β(p-GSK-3β) and β-catenin(by Western blot).Results:Compared with the corresponding Sham groups, the serum cTnI concentration was significantly increased, the expression of TNF-α, IL-1β and IL-6 mRNA and expression of p-AKT, p-GSK-3β and β-catenin in myocardial tissues were up-regulated, the expression of TIPE2 was down-regulated( P<0.05), and the pathological changes of myocardium were found in corresponding CLP groups. Compared with group WT-CLP, the serum cTnI concentration was significantly increased, the expression of TNF-α, IL-1β and IL-6 mRNA and expression of p-AKT, p-GSK-3β and β-catenin in myocardial tissues were up-regulated, the expression of TIPE2 was down-regulated( P<0.05), and the pathological changes of myocardium were aggravated in group KO-CLP( P<0.05). Conclusions:TIPE2 reduces the myocardial injury probably through inhibiting the AKT/GSK-3β/β-catenin signaling pathway in septic mice.

ObjectiveTo observe the clinical effect of Yiqi Liangxue Shengji Formula (益气凉血生肌方, YLSF) on recurrence of angina pectoris and quality of life at eight weeks after perecutaneous coronary intervention (PCI). MethodsEighty-two coronary artery disease (CAD) patients with qi deficiency and blood stasis and binding of stasis and heat syndrome who had underwent PCI were randomly divided into two groups with 41 patients each in the treatment group and the control group. Based on conventional western medicine after PCI, patients in the treatment group orally took YLSF granules while those in the control group were administered with placebo, one dose daily for 8 weeks. The recurrence rate of angina pectoris and readmission rate within eight weeks after PCI were recorded. Before and after treatment, total traditional Chinese medicine (TCM) syndrome score, Seattle Angina Questionnaire (SAQ) scores (physical limitation, angina stability, angina frequency, treatment satisfaction and disease perception), and the SF-36 scores for quality of life (physical and mental health) were evaluated. The adverse reactions during medication in both groups were recorded. ResultsWithin eight weeks after PCI, the recurrence rate of angina pectoris in the treatment group (4/41, 9.76%) was significantly lower than that in the control group (11/41, 26.83%, P<0.05). The readmission rate in the treatment group was 2.44% (1/41), while that in the control group was 12.20% (5/41), with no significantly statistical difference (P>0.05). After treatment, total TCM syndrome score significantly decreased in both groups, while in terms of quality of life, the SAQ scores on domains of angina stability, angina frequency and disease perception as well as SF-36 total scores, physical health and mental health scores significantly increased (P<0.05 or P<0.01). Compared between the two groups, total TCM syndrome score was significantly lower in the treatment group than the control group (P<0.01), while no significant differences were found in SAQ scores and SF-36 total, physical and mental health scores (P>0.05). No adverse reactions occurred in both groups during the treatment period. ConclusionYLSF can reduce the recurrence rate of angina pectoris within eight weeks after PCI for coronary artery disease, and can improve the TCM syndrome score, and have sound safety, with comparable effect to that of placebo in improving postoperative short-term quality of life.

Mitochondria are the main site of energy metabolism in cardiomyocytes, and at the same time mediate apoptosis and immune response, so mitochondrial dysfunction is closely related to the development of heart failure. Combined with the pathogenesis of mitochondrial dysfunction and heart failure, it is proposed that the mitochondrial function is similar to "sweat pore - collaterals - zang and fu organs", according to which the treatment of heart failure is based on the theory of "sweat pore - collaterals - zang and fu organs". It is believed that the core mechanism of heart failure is qi deficiency, and qi deficiency leads to the weakness of the sweat pore opening and closing, or even the sweat pore closure, then resulting in qi deficiency and blood stasis, collaterals stagnation fail to flourish, and qi, blood, and body fluids can not infiltrate and nourish zang-fu organs, so that the heart fail to be nourished, and the disease will develop. The treatment should be based on the method of boosting qi and opening sweat pore, using acridity to unblock the collaterals, and invigorating blood and draining water, with medicinal of boosting qi, invigorating blood, and draining water as treatment.

Previous studies suggest that the reduction of SMAD3 (mothers against decapentaplegic homolog 3) has a great impact on tumor development, but its exact pathological function remains unclear. In this study, we found that the protein level of SMAD3 was greatly reduced in human-grade IV glioblastoma tissues, in which LAMP2A (lysosome-associated membrane protein type 2A) was significantly up-regulated. LAMP2A is a key rate-limiting protein of chaperone-mediated autophagy (CMA), a lysosome pathway of protein degradation that is activated in glioma. We carefully analyzed the amino-acid sequence of SMAD3 and found that it contained a pentapeptide motif biochemically related to KFERQ, which has been proposed to be a targeting sequence for CMA. In vitro, we confirmed that SMAD3 was degraded in either serum-free or KFERQ motif deleted condition, which was regulated by LAMP2A and interacted with HSC70 (heat shock cognate 71 kDa protein). Using isolated lysosomes, amino-acid residues 75 and 128 of SMAD3 were found to be of importance for this process, which affected the CMA pathway in which SMAD3 was involved. Similarly, down-regulating SMAD3 or up-regulating LAMP2A in cultured glioma cells enhanced their proliferation and invasion. Taken together, these results suggest that excessive activation of CMA regulates glioma cell growth by promoting the degradation of SMAD3. Therefore, targeting the SMAD3-LAMP2A-mediated CMA-lysosome pathway may be a promising approach in anti-cancer therapy.
