ABSTRACT

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.

ABSTRACT

Objective To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. Methods Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. Results A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ2= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ2 = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). Conclusions The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

ABSTRACT

Objective:To explore the characteristics of sleep disorders in patients with Parkinson's disease (PD) and its correlation with homocysteine.Methods:Totally 75 PD patients hospitalized in the department of neurology from January 2017 to June 2021 were selected and divided into sleep disorder group ( n=39) and non-sleep disorder group ( n=36)according to polysomnography, Parkinson's disease sleep scale(PDSS) and Epworth sleepiness scale(ESS). The basic clinical data, hematological examination results, scale evaluation data and polysomnography monitoring data of the above patients were collected during hospitalization to analyze the sleep characteristics of patients with Parkinson's disease and its correlation with homocysteine.SPSS 26.0 statistical analysis software was used for t test, Mann-Whitney U test, Pearson analysis, Spearman analysis and multivariate Logistic analysis. Results:The sleep efficiency (56.82±19.07)%, N2 phase ratio(48.67±17.70)%, N3 phase ratio(9.20%(19.00%)) and the leg movement micro-arousal index(0(1.20)) in the sleep disorder group were lower than those in the non-sleep disorder group (sleep efficiency (82.15±5.55)%, N2 phase ratio(57.02±2.80)%, N3 phase ratio(20.01%(3.93%)), the leg movement micro-arousal index(1.15(1.80)). The differences were statistically significant ( t/ Z=-6.087, -2.905, -3.773, -3.683, all P<0.05). The proportion of AHI (0.90(14.60)), N1 stage (19.50%(15.70%)), and periodic limb index (0(24.80)) in sleep disorder group were higher than those in non-sleep disorder group (AHI (0.60(0.30)), N1 stage (12.15%(3.15%)), and periodic limb index (0(0)). The difference was statistically significant ( Z=2.154, 5.250, 3.559, all P<0.05). The homocysteine (15.80(3.90) μmol/L), NMSS-insomnia correlation score (3.00(5.00)), MDS-UPDRS-Ⅰ(7.00 (10.00)), MDS-UPDRS-Ⅲ (23.00 (16.00)) in the sleep disorder group were higher than those in the non-sleep disorder group (homocysteine (14.10 (4.20)μmol/L), NMSS-insomnia correlation score (0(1.00)), MDS-UPDRS-Ⅰ(3.00 (2.00)), MDS-UPDRS-Ⅲ (17.00 (4.00)), and the differences were statistically significant( Z=2.557, 4.487, 2.952, 2.180, all P<0.05). The NMSS-olfactory correlation scores (2.00(4.00)) and PDSS (99.00 (40.00)) were lower than those in the non-sleep disorder group (NMSS-olfactory correlation scores (4.50 (7.00)) and PDSS (122.00 (28.00)), and the differences were statistically significant ( Z=2.450, 4.126, both P<0.05). Hcy was positively correlated with sleep disorder in PD patients ( r=0.297, P<0.05). Binariate logistic regression analysis showed that elevated homocysteine level might be a risk factor for sleep disorder in PD patients ( β=0.193, OR=1.213, 95% CI=1.029-1.430). Conclusion:Parkinson's disease patients with sleep disorder have the characteristics of sleep structure disorder, often accompanied by more serious motor disorders, and the olfactory function impairment is relatively mild. Elevated homocysteine levels may be a risk factor for sleep disorder in Parkinson's disease.

ABSTRACT

As a group of nonspecific inflammatory diseases affecting the intestine, inflammatory bowel disease (IBD) exhibits the characteristics of chronic recurring inflammation, and was proven to be increasing in incidence (Kaplan, 2015). IBD induced by genetic background, environmental changes, immune functions, microbial composition, and toxin exposures (Sasson et al., 2021) primarily includes ulcerative colitis (UC) and Crohn's disease (CD) with complicated clinical symptoms featured by abdominal pain, diarrhea, and even blood in stools (Fan et al., 2021; Huang et al., 2021). UC is mainly limited to the rectum and the colon, while CD usually impacts the terminal ileum and colon in a discontinuous manner (Ordás et al., 2012; Panés and Rimola, 2017). In recent years, many studies have suggested the lack of effective measures in the diagnosis and treatment of IBD, prompting an urgent need for new strategies to understand the mechanisms of and offer promising therapies for IBD.

ABSTRACT

The onset of inflammatory bowel disease (IBD) involves many factors, including environmental parameters, microorganisms, and the immune system. Although research on IBD continues to expand, the specific pathogenesis mechanism is still unclear. Protein modification refers to chemical modification after protein biosynthesis, also known as post-translational modification (PTM), which causes changes in the properties and functions of proteins. Since proteins can be modified in different ways, such as acetylation, methylation, and phosphorylation, the functions of proteins in different modified states will also be different. Transitions between different states of protein or changes in modification sites can regulate protein properties and functions. Such modifications like neddylation, sumoylation, glycosylation, and acetylation can activate or inhibit various signaling pathways (e.g., nuclear factor-‍κB (NF-‍κB), extracellular signal-regulated kinase (ERK), and protein kinase B (AKT)) by changing the intestinal flora, regulating immune cells, modulating the release of cytokines such as interleukin-1β (IL-‍‍1β), tumor necrosis factor-α (TNF‍-‍α), and interferon-‍γ (IFN-‍γ), and ultimately leading to the maintenance of the stability of the intestinal epithelial barrier. In this review, we focus on the current understanding of PTM and describe its regulatory role in the pathogenesis of IBD.

ABSTRACT

Hepatic encephalopathy is a common metabolic neuropsychiatric syndrome in the development of end-stage liver disease. Since the concept of intestinal-liver-brain axis was proposed, the relationship between the pathogenesis of hepatic encephalopathy and the gut microbiota has been a hot research topic. In recent years, studies have confirmed that gut microbiota is involved in and affects various pathological processes of hepatic encephalopathy. This article combines the latest research progress at home and abroad to elaborate on the research status of regulating gut microbiota and thus interfering with the pathological process of hepatic encephalopathy, hoping to provide new ideas and methods for the intervention of hepatic encephalopathy based on the regulation of gut microbiota.

ABSTRACT

A high performance liquid chromatography( HPLC) method was established for the fast,and precise determination of ten nucleosides in Fritillariae Cirrhosae Bulbus and its counterfeits. Then multivariate statistical analyses,such as clustering analysis,principal component analysis( PCA),and Fisher' s linear discriminant analysis( LDA),were conducted to establish a discriminant function model for an integrated analysis. The results indicated that data acquisition time of a single sample was shortened within 16 min by the HPLC method. In the range of 5-1 000 mg·kg~(-1),the mass concentrations of all nucleosides exhibited good linear relationships with the corresponding peak areas( R2> 0. 999). The spiked recoveries were in the range of 93. 83%-108. 9% with RSDs of0. 12%-1. 3%( n = 5). The limit of quantitation( LOQ) was 0. 98-4. 13 mg·kg~(-1). As revealed by the clustering analysis,Fritillariae Cirrhosae Bulbus and the counterfeits could be discriminated into two clusters based on the content of nucleosides. Fisher's LDA could achieve this discrimination,while PCA dimension reduction failed. The accuracy of the discriminant function model established on the screened characteristic indicators reached 97. 5%. The present study proposed a new identification method of Fritillariae Cirrhosae Bulbus with one-dimensional indicators,which is simple,accurate,and reliable. It can provide a scientific basis for further optimizing the identification techniques for Fritillariae Cirrhosae Bulbus and inspiration for quality control strategy development of Chinese medicinal materials.

ABSTRACT

Ischemic stroke is a severe disorder resulting from acute cerebral thrombosis. Here we demonstrated that post-ischemic treatment with ciclopirox olamine (CPX), a potent antifungal clinical drug, alleviated brain infarction, neurological deficits and brain edema in a classic rat model of ischemic stroke. Single dose post-ischemic administration of CPX provided a long-lasting neuroprotective effect, which can be further enhanced by multiple doses administration of CPX. CPX also effectively reversed ischemia-induced neuronal loss, glial activation as well as blood-brain barrier (BBB) damage. Employing quantitative phosphoproteomic analysis, 130 phosphosites in 122 proteins were identified to be significantly regulated by CPX treatment in oxygen glucose deprivation (OGD)-exposed SH-SY5Y cells, which revealed that phosphokinases and cell cycle-related phosphoproteins were largely influenced. Subsequently, we demonstrated that CPX markedly enhanced the AKT (protein kinase B, PKB/AKT) and GSK3 (glycogen synthase kinase 3) phosphorylation in OGD-exposed SH-SY5Y cells, and regulated the cell cycle progression and nitric oxide (NO) release in lipopolysaccharide (LPS)-induced BV-2 cells, which may contribute to its ameliorative effects against ischemia-associated neuronal death and microglial inflammation. Our study suggests that CPX could be a promising compound to reduce multiple ischemic injuries; however, further studies will be needed to clarify the molecular mechanisms involved.

ABSTRACT

Objective:To evaluate the effect of uncoupling protein 1 (UCP1) expression of perirenal fat on the prognosis of clear cell renal cell carcinoma (ccRCC) .Methods:From Feb. 2013 to Oct. 2013 and Mar. 2015 to Oct. 2015, 98 patients with ccRCC who underwent retroperitoneal laparoscopic radical nephrectomy were analyzed. UCP1 mRNA of perirenal fat around tumor was detected by RT-qPCR. Preoperative Computed tomography (CT) images were used to evaluate the thickness and adhesiveness of perirenal fat. According to the UCP1 mRNA value, the patients were divided into high UCP1 group (42 cases) and low UCP1 group (56 cases) . The general clinical data, perirenal fat thickness and adhesiveness were compared, and Kaplan Meier curve was used to evaluate the difference of progression free survival (PFS) between the two groups. Univariate and multivariate Cox analysis were used to determine the potential independent prognostic factors of PFS.Results:In the high UCP1 group, the renal fat thickness, the ratio of fat adhesion, the ratio of Ⅲ to Ⅳ in Fuhrman grade and the ratio of >T2 in T stage were higher than those in the low UCP1 group[ (13.84±2.41) vs (10.75±1.99) , 42.86% vs 16.07%, 28.57% vs 8.93%, 21.43% vs. 5.36%; P=0.000, P=0.003, P=0.011, P= 0.037]. During the follow-up period (median, 62.0 months) , 15 cases (12 cases of high UCP1 group, 3 case of low UCP1 group) developed tumor progression. Kaplan Meier curve showed that PFS of high UCP1 group was worse than that of low UCP1 group (71.43% vs 94.64%, P=0.001) . Cox regression analysis showed that high UCP1 expression and high T stage were significantly correlated with low PFS ( β=1.334, RR=3.796, 95% CI=1.009-14.280, P= 0.048; β=2.886, RR=17.930, 95% CI=5.538-58.047, P=0.000) . Conclusions:The increased UCP1 expression of perirenal fat may be an independent risk factor of tumor progression in ccRCC. Combined with the assessment of browning of perirenal adipose tissue may be helpful for risk stratification of ccRCC patients after surgery.

ABSTRACT

On the basis of the chromogenic reaction between Hg and CuI, a semi-quantitative solid sampling Hg analyzer comprising the catalytic furance, Hg testing tube, air pump and smart cellphone was developed. White carrier 101 was chosen as the adsorbent for CuI to react with Hg from the catalytic furnace. The established Hg analyzer can not only visually recognize the coloration when Hg exceeding the limit standard, but also semi-quantitatively detect the Hg content in cosmetics fast using a smart cellphone and RGB analysis software, after direct solid sampling introduction of cosmetics sample. The instrumental detection limit ( LOD) of mercury was 50 ng, the linearity ranged from 50 ng to 2500 ng, the linear regression coefficient ( R2) was higher than 0. 97, and the RSD of the corresponding RGB values was 6% ( n=11 ) . Nine real cosmetics samples were measured by the established method, whose relative differences of Hg contents with that by the standard method (Safety Technical Specification for Cosmetics, 2015 edition) were less than 10% . The whole analytical time can be controlled within 5 min. The established instrumental method is simple, fast, accurate and visual, and extremely suitable to fast and on-site monitoring of Hg in cosmetics samples.

ABSTRACT

Chronic hyperglycemia is often accompanied by abnormal lipid metabolism, hypertension, low-grade systemic inflammation and oxidative stress.These factors increase the risk of cardiovascular disease(CVD)in type 2 diabetes mellitus(T2DM)patients.Comprehensive treatment of T2DM should emphasize the improvement of abnormal lipid metabolism, prevention of weight gain and reduction of the CVD risk in addition to proper glycemic control.Incretin, as a new hypoglycemic drug, has more advantages in improving glucose and lipid metabolism, finally to reduce cardiovascular risk.Through possible mechanisms including direct influence on liver lipid metabolism, change of fat mobilization and delay of gastric emptying, incretin shows positive influence on the lipid metabolic markers such as low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, triglycerides, and total cholesterol, while it improves glucose control.Thus, incretin plays an important role in the comprehensive management of type 2 diabetes mellitus.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the effect of globular adiponectin on angiogenesis of ovarian microvascular endothelial cells (OMECs).</p><p><b>METHODS</b>Mouse OMECs were isolated and purified by density gradient centrifugation with Percoll and identified by immunofluorescence analysis of follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR), and endothelial cell marker von Willebrand factor (vWF). The capillary-like tube formation of OMECs was determined by vascular endothelial growth factor A (VEGFA) treatment in Matrigel matrix. OMECs treated with recombinant globular adiponectin protein were examined for cell proliferation with MTS assay and cell migration with scratch wound healing assay, and capillary-like tube formation was tested in Matrigel matrix. Western blotting was performed to detect the effect of globular adiponectin on AMPK phosphorylation.</p><p><b>RESULTS</b>The signals of LHR and vWF, but not that of FSHR, were detected in the isolated cells. VEGFA treatment of the cells induced capillary-like tube formation, indicating their properties of ovarian-specific endothelial cells. Treatment with 1 and 3 µg/mL of recombinant globular adiponectin significantly increased the number of OMECs by (158.72∓14.50) % and (186.50∓4.20)% (P<0.01) and resulted in scratch wound closure rates of (49.43∓3.43)% (P<0.05) and (69.67∓1.2) % (P<0.01) respectively. The cells treated with 3 µg/mL globular adiponectin formed a capillary-tube length 6.63∓0.66 folds greater than that formed by the control cells (P<0.01). Treatment of the cells with 3 µg/mL globular adiponectin for 15 and 30 min resulted in pAMPK/AMPK ratios of 0.86∓0.08 and 0.66∓0.13, respectively significantly higher than that in the control cells (0.13∓0.12, P<0.01). Compound C obviously suppressed the tube formation and AMPK phosphorylation induced by globular adiponectin.</p><p><b>CONCLUSION</b>Globular adiponectin promotes angiogenesis of OMECs through activation of the AMPK signal pathway.</p>

ABSTRACT

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

ABSTRACT

AIM@#To investigate the molecular signaling mechanism by which the plant-derived, pentacyclic triterpene maslinic acid (MA) exerts anti-diabetic effects.@*METHOD@#HepG2 cells were stimulated with various concentrations of MA. The effects of MA on glycogen phosphorylase a (GPa) activity and the cellular glycogen content were measured. Western blot analyses were performed with anti-insulin receptor β (IRβ), protein kinase B (also known as Akt), and glycogen synthase kinase-3β (GSK3β) antibodies. Activation status of the insulin pathway was investigated using phospho-IRβ, as well as phospho-Akt, and phospho-GSK3β antibodies. The specific PI3-kinase inhibitor wortmannin was added to the cells to analyze the Akt expression. Enzyme-linked immunosorbent assay (ELISA) was used to measure the effect of MA on IRβ auto-phosphorylation. Furthermore, the effect of MA on glycogen metabolism was investigated in C57BL/6J mice fed with a high-fat diet (HFD).@*RESULTS@#The results showed that MA exerts anti-diabetic effects by increasing glycogen content and inhibiting glycogen phosphorylase activity in HepG2 cells. Furthermore, MA was shown to induce the phosphorylation level of IRβ-subunit, Akt, and GSK3β. The MA-induced activation of Akt appeared to be specific, since it could be blocked by wortmannin. Finally, MA treatment of mice fed with a high-fat diet reduced the model-associated adiposity and insulin resistance, and increased the accumulated hepatic glycogen content.@*CONCLUSION@#The results suggested that maslinic acid modulates glycogen metabolism by enhancing the insulin signaling pathway and inhibiting glycogen phosphorylase.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of glutamine combined with ulinastatin on inflammatory response of patients with severe burn injury.</p><p><b>METHODS</b>Sixty patients with severe burn injury admitted to our burn wards from January 2010 to December 2011 conforming to the study criteria were divided into control group (C, n = 20), glutamine group (G, n = 20), and glutamine combined with ulinastatin group (G + U, n = 20) according to the random number table. Another 10 healthy volunteers were chosen as normal control group (NC). Isonitrogenous and isocaloric nutrition supports were given to patients in groups C, G, and G + U from post burn day (PBD) 2. 0.3 g/kg protein in the form of glutamine dipeptide was given to patients in group G for 10 days. 0.3 g/kg protein was given to patients in group G + U for 10 days with the same amount of glutamine dipeptide as that in group G, followed by intravenous injection of 100 kU ulinastatin (once per 8 hours) for 7 days during 10 days. The nitrogen concentration of 24 h urine was determined with Kieldahl nitrogen determination method, and nitrogen balance was calculated one day before treatment and ten days after treatment. Meanwhile, the levels of D-lactate in serum was determined by colorimetric method, the levels of diamine oxidase (DAO), TNF-α, and IL-6 by enzyme-linked immunosorbent assay, and LPS level by kinetic turbidimetric assay with TAL. Above-mentioned indexes were also examined in group NC. The wound healing rate on PBD 30, total hospital stay days, and the incidence of burn sepsis of all burn patients were recorded. Data were processed with one-way analysis of variance, LSD test, t test, and chi-square test.</p><p><b>RESULTS</b>Compared with that in group C [(-5.40 ± 1.67) g/d], nitrogen balance in group G was significantly increased ten days after treatment [(-1.35 ± 0.59) g/d, P < 0.01]. The serum levels of D-lactate, DAO, LPS, TNF-α, and IL-6 in group G ten days after treatment were significantly lower than those in group C (P < 0.05 or P < 0.01). No statistically significant difference was observed in nitrogen balance and the serum levels of D-lactate, DAO between group G + U and group G (P values all above 0.05). The serum levels of LPS, TNF-α, and IL-6 in group G + U ten days after treatment were respectively (0.167 ± 0.064) EU/mL, (43 ± 14) pg/mL, (139 ± 23) pg/mL, which were significantly lower than those in group G [(0.240 ± 0.079) EU/mL, (59 ± 8) pg/mL, (195 ± 31) pg/mL, respectively, P < 0.05 or P < 0.01]. The would healing rate on PBD 30 and total hospital stay days in group G were respectively higher and shorter than those in group C (P values all below 0.01), but no statistically significant difference in the incidence of burn sepsis was found between them (P > 0.05). The would healing rate on PBD 30 in group G+U [(96 ± 4)%] was enhanced, and total hospital stay days [(41 ± 4) d] were lowered than those in group G [(88 ± 7)%, (49 ± 5)d, P values all below 0.01]. The incidence of burn sepsis of patients in group G + U (5%) was significantly lower than that in group C (35%, χ(2) = 6.234, P < 0.05).</p><p><b>CONCLUSIONS</b>Glutamine combined with ulinastatin treatment can alleviate damage to intestine after severe burn injury, lower the serum level of inflammatory cytokines, promote wound healing, and reduce the incidence of burn sepsis.</p>

ABSTRACT

Objective: To investigate whether Shuxuening injection has a protective effect on myocardial injury in rats with cecal ligation and puncture(CLP)- induced sepsis. Methods: Thirty SD rats were randomly allocated to Sham group, CLP group and Shuxuening group (SXN group). In the Shuxuening group, Shuxuening injection was intraperitoneally injected at a dose of 1 mg(0.3 ml)/body weight 1 h before CLP challenge. The sham and CLP groups received an equal volume of saline injection (0.3 ml/kg) at the same time points. Six hours later, the blood samples were obtained from abdominal aorta to determine the contents of TnT, TNF-α, and IL-1β. Meanwhile, MDA contents and SOD activities in myocardial tissues were also tested and the pathologic changes of the myocardial tissue were observed by H-E staining. Results: Compared with CLP group, the serum contents of TnT, TNF-α, and IL-1β and myocardial tissue MDA were decreased in Shuxuening group; and the myocardial tissue SOD activities were significantly increased in Shuxuening group (P<0.05 or 0.01). Microscope observation showed that the degrees of myocardial congestion, edema, and inflammatory cell infiltration were greatly improved in the Shuxuening group compared with in the CLP group. Conclusion: Our results suggest that Shuxuening can protect against CLP-induced myocardial injury in rats, probably through scavenging free radical and inhibiting release of inflammatory mediators.
