ABSTRACT
OBJECTIVE: In this study, the efficacy and safety of salvianolate were compared with enoxaparin in the prevention of perioperative deep vein thrombosis in gastrointestinal surgery. METHODS: From October 2017 to September 2019, 563 patients who underwent gastrointestinal surgery were collected. Based on the inclusion and exclusion criteria, 119 patients were divided into two groups: enoxaparin group (n = 65) and salvianolate group (n = 54). Comparisons were made regarding the outcomes: prothrombin time (PT), prothrombin activity (PTA), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (FIB), thrombin time (TT), D-dimer level (D-D), platelet count (PLT), hematokrit (HCT), and incidence of deep vein thrombosis (DVT). RESULTS: The main outcomes showed no significance between enoxaparin group and salvianolate group (p > .05). The incidence of DVT in salvianolate group was 1.85%, significantly lower than that in enoxaparin group (12.3%) (p < .05). No serious adverse reactions occurred in the two groups during treatment. CONCLUSION: Compared with enoxaparin, salvianolate has an advantage in the prevention of perioperative thrombosis in gastrointestinal surgery with a lower incidence of DVT.

Liver fibrosis is a global health problem caused by a number of diseases related to liver damage. 6-Shogaol is a biologically active substance derived from the rhizome of Zingiber officinale Roscoe with anti-tumor, anti-inflammatory, and antioxidant properties. To explore the effects of 6-Shogaol on liver fibrosis, we used a mouse model of the condition in which mice were injected intraperitoneally with carbon tetrachloride (CCl4) at a dose of 2 mL/kg three times per week for a period of 4 weeks. 6-Shogaol was administered orally at two different doses (5 mg/kg, 20 mg/kg) 30 min before CCl4 injection. CCl4 induced severe liver injury and fibrosis, as indicated by significant inflammatory cell infiltration, disordered liver structure, increased activities of aspartate aminotransferase and alanine aminotransferase (liver damage markers) in serum, elevated collagen deposition, and overexpressed alpha-smooth muscle actin (α-SMA, marker of hepatic stellate cells activation) in liver tissues, whereas 6-Shogaol administration rescued those alterations dose-dependently. We found that 6-Shogaol suppressed CCl4-induced inflammatory response by inhibiting macrophage recruitment, release of pro-inflammatory factors, and activation of the NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome in liver tissues. Additionally, we demonstrated that 6-Shogaol blocked CCl4-induced activation of the nuclear factor-kappa B (NF-κB) pathway, which is a vital transcriptional regulator of the inflammatory response. Altogether, this study demonstrates that 6-Shogaol can prevent CCl4-induced liver fibrosis by suppressing inflammatory response through the NF-κB pathway and suggests that 6-Shogaol can be used for liver fibrosis prevention.

To investigate therapeutic target for ligustrazine during liver fibrosis in an ethanol-induced biliary atresia rat model and transforming growth factor-ß (TGF-ß) induced hepatic stellate cell activation cell model, and the underlying mechanism, a total of 30 rats were randomly assigned into five groups (n = 6 per group): control, sham, ethanol-induced biliary atresia model, model plus pirfenidone, and model plus ligustrazine groups. The liver changes were assessed using H&E and Masson staining and transmission electron microscopy. Expression of miR-145 and mRNA and protein levels of TGF-ß/smads pathway-related proteins were detected. HSC-T6 cells were infected with LV-miR or rLV-miR-145 in the presence or absence of SMAD3 inhibitor SIS3 and treated with 2.5 ng/ml TGF-ß1 and then with ligustrazine. Collected cells were subjected to detect the expression of miR-145 and mRNA and protein expression levels of TGF-ß/smads pathway-related proteins. Ligustrazine rescued liver fibrogenesis and pathology for ethanol-caused bile duct injury, revealed by decreased α-smooth muscle actin and collagen I expression and liver tissue and cell morphology integrity. Further experiments showed that ligustrazine inhibited intrinsic and phosphorylated Smad2/3 protein expression and modification. Similar results were obtained in cells. In addition, ligustrazine altered miR-145 expression in both animal and cell models. Lentivirus mediated miR-145 overexpression and knockdown recombinant virus showed that miR-145 enhanced the TGF-ß/Smad pathway, which led to hepatic stellate cell activation, and ligustrazine blocked this activation. This work validated that ligustrazine-regulated miR-145 mediated TGF-ß/Smad signaling to inhibit the progression of liver fibrosis in a biliary atresia rat model and provided a new therapeutic strategy for liver fibrosis. SIGNIFICANCE STATEMENT: With an ethanol-induced biliary atresia rat model, ligustrazine was found to rescue liver fibrogenesis and pathology for ethanol caused bile duct injury, revealed by decreased α-smooth muscle actin and collagen I expression and liver tissue and cell morphology integrity. Furthermore, we found ligustrazine upregulated miR-145 expression and inhibited TGF-ß/SMAD signaling pathway both in vivo and in vitro. In addition, overexpression and knockdown of miR-145 confirmed that miR-145 is involved in the ligustrazine inhibition of liver fibrosis through the TGF-ß/SMAD signaling pathway.

BACKGROUND: Salvianolate, a common drug for stabilizing heart disease and Angina Pectoris, is considered to be off-label for preventing venous thromboembolism (VTE) or anticoagulation at present. However, many clinical studies have showed that salvianolate can effectively inhibit the deep-vein thrombosis (DVT) incidence, and prevent VTE of perioperative patients in the real world in China. OBJECTIVE: This analysis aimed to evaluate the effectiveness and safety of salvianolate in preventing VTE in perioperative patients. METHODS: Databases of PubMed, Cochrane Library, Embase, CNKI, Wanfang and VIP were searched until July 2019. Literature retrieval, data extraction and quality assessment were independently completed by two researchers and checked with each other. Review Manager 5.2 software was applied for meta-analysis. RESULTS: A total of 429 studies were retrieved, including 11 randomized controlled trials (RCTs) with a total of 1149 subjects. Compared with low molecular weight heparin (LMWH) group alone, salvianolate combined LMWH group had lower DVT incidence in preventing perioperative thrombosis (2.75% and 14.23%, OR: 0.21, 95% CI:[0.08,0.53]; Pâ=â.0009). The incidence of adverse reactions of experimental group was similar to that of control group (1.79% and 2.31%, OR: 0.65, 95% CI:[0.18,2.35]. Pâ=â.51). Compared with the control group, D-dimer level (D-D), platelet count (PLT), fibrinogen (FIB), whole blood high shear viscosity (WBHSV), and whole blood low shear viscosity (WBLSV) were all significantly decreased (Pâ<â.01), and prothrombin time (PT) was significantly increased (Pâ<â.05). CONCLUSION: Salvianolate combined LMWH has better effectiveness and the same safety in preventing venous thromboembolism in perioperative patients. However, due to the small number of included literatures, large sample studies are still needed to further verify this conclusion.

Diarrheal irritable bowel syndrome (IBS-D) is a chronic functional bowel disease with no clear diagnostic markers and no satisfactory treatment strategies. In recent years, the importance of intestinal microstructure and function in IBS-D has been emphasized. However, the intestinal tissue proteomics of IBS-D patients has not been analyzed. Here, we systematically analyzed the molecule profiling of the intestinal tissues in IBS-D patients through tandem mass tag (TMT)-based proteomics for the first time, aiming to reveal the pathogenesis and provide evidence for diagnosis and treatment of IBS-D. Five IBS-D patients and five healthy subjects were selected, biopsy tissue samples from the junction of sigmoid and rectum were analyzed by TMT proteomics. Differentially expressed proteins were obtained and bioinformatics analysis was performed. Furthermore, parallel reaction monitoring (PRM) and q-PCR detection were applied to validate the differentially expressed proteins. Eighty differentially expressed proteins were screened, 48 of which were up-regulated and 32 were down-regulated (fold change >1.2, P < 0.05). Bioinformatics analysis showed that these proteins were significantly enriched in the nutrient ingestion pathways which are related to immune molecules. SELENBP1, VSIG2, HMGB1, DHCR7, BCAP31 and other molecules were significantly changed. Our study revealed the underlying mechanisms of IBS-D intestinal dysfunction. SIGNIFICANCE: Irritable bowel syndrome with diarrhea (IBS-D) is a worldwide chronic intestinal disease with no definite diagnostic markers. It is still a challenge to accurately locate the pathogenesis of patients for appropriate treatment strategy. Established proteomics studies of IBS-D are only based on urine, blood, or tissue samples from animals. Our study was the first TMT proteomics analysis on intestinal biopsy tissues of patients with IBS-D, which revealed the changes of molecular spectrum of actual intestinal conditions in patients with IBS-D. Some important molecules and signaling pathways have been found abnormal in our study, which were related with nutrient uptake. They not only provided preliminary clues for low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) intolerance, an unsolved conundrum of IBS-D, but also revealed obscure problems of protein, lipid, and other nutrients ingestion in IBS-D patients. Some of these differentially expressed molecules have been preliminarily verified, and will may be potential candidate molecules for diagnostic markers of IBS-D.

INTRODUCTION: The aim of this study was to evaluate the efficacy and safety of azithromycin (AZI) combined with glucocorticoid (GC) in the treatment of children with refractory Mycoplasma pneumoniae. METHODS: Computer search for PubMed, EMbase, Cochrane Library, China Biomedical Literature Database (CBMdisc), China Knowledge Network (CNKI), Wanfang, VIP (VIP), and a randomized controlled trial (RCT) of AZI combined with GC in the treatment of children with refractory Mycoplasma pneumoniae pneumonia test (RCT), the search time limit is built until March 20, 2019. Two researchers independently performed literature screening, data extraction, and literature risk bias, and meta-analysis was performed using RevMan 5.3 software. RESULTS: A total of 12 RCTs were included, including 1130 patients. Meta-analysis showed that AZI combined with GC therapy significantly improved the total effective rate of the disease compared with the conventional treatment group (odds ratio [OR]â=â6.37; 95% confidence interval [CI] 4.03, 10.07; Pâ<â.00001; Iâ=â0%), effectively shortened the antipyretic time (SMDâ=â-2.29; 95% CI -2.70, -1.88; Pâ<â.0001); promoted lung inflammation absorption (SMDâ=â-1.89; 95% CI -2.38, -1.40; Pâ<â.0001), reduced cough time (SMDâ=â-2.39; 95% CI -2.80, -1.99; Pâ<â.0001); shortened hospital stay (SMDâ=â-2.19; 95% CI -3.21, -1.17; Pâ<â.0001); improved imaging findings (ORâ=â5.38; 95% CI 1.09, 26.51, Pâ=â.04); reduced inflammation index (SMDâ=â-3.15; 95% CI -4.93, -1.36; Pâ=â.004); improved immune function (SMDâ=â1.29; 95% CI -0.02, 2.60; Pâ<â.0001); had no significant adverse reactions (ORâ=â1.18; 95% CI 0.71, 1.98; Pâ=â.53). CONCLUSIONS: According to the current limited research evidence, the addition of GCs to the conventional treatment of refractory Mycoplasma pneumoniae in children can improve the clinical efficacy to a certain extent, and the safety is better. However, due to the quality and quantity of the included literature, the conclusions of this study need to be confirmed by more high-quality studies.

BACKGROUND AND PURPOSE: Trauma-induced osteonecrosis of the femoral head (TIONFH) is a major complication of femoral neck fractures. Degeneration and necrosis of subchondral bone can cause collapse, which results in hip joint dysfunction in patients. The destruction of bone metabolism homeostasis is an important factor for osteonecrosis. MicroRNAs (miRNAs) have an important role in regulating osteogenic differentiation, but the mechanisms underlying abnormal bone metabolism of TIONFH are poorly understood. In this study, we screened specific miRNAs in TIONFH by microarray and further explored the mechanism of osteogenic differentiation. DESIGN: Blood samples from patients with TIONFH and patients without necrosis after trauma were compared by microarray, and bone collapse of necrotic bone tissue was evaluated by micro-CT and immunohistochemistry. To confirm the relationship between miRNA and osteogenic differentiation, we conducted cell culture experiments. We found that many miRNAs were significantly different, including miR-93-5p; the increase in this miRNA was verified by Q-PCR. Comparison of the tissue samples showed that miR-93-5p expression increased, and alkaline phosphatase (ALP) and osteopontin (OPN) levels decreased, suggesting miR-93-5p may be involved in osteogenic differentiation. Further bioinformatics analysis indicated that miR-93-5p can target bone morphogenetic protein 2 (BMP-2). A luciferase gene reporter assay was performed to confirm these findings. By simulating and/or inhibiting miR-93-5p expression in human bone marrow mesenchymal stem cells, we confirmed that osteogenic differentiation-related indictors, including BMP-2, Osterix, Runt-related transcription factor, ALP and OPN, were decreased by miR-93-5p. CONCLUSION: Our study showed that increased miR-93-5p in TIONFH patients inhibited osteogenic differentiation, which may be associated with BMP-2 reduction. Therefore, miR-93-5p may be a potential target for prevention of TIONFH.
