Objective: To analyze the correlation of idiosyncratic hepatotoxicity of Zhuangguguanjie Wan (ZGW) with 27 cytokines. Methods: After 12 h fasting, SD rats were ig with ZGW at a single dose of 3.8 g/kg, and injected with lipopolysaccharide (LPS) at a dosage of 2.8 mg/kg via tail vein after 2 h. The rats were anesthetized with chloral hydrate after 10 h LPS administration, and then the blood samples were collected from the inferior vena cava and liver tissue was also obtained. Alanine aminotransferase (ALT) activity in serum and levels of 27 cytokines in liver tissue were tested. Correlation analysis of ALT and cytokines were performed using R 3.2.4 software. Results: Correlation analysis showed that there was a high positive correlation between ALT and macrophage inflammatory protein-1α (MIP-1α) or vascular endothelial growth factor (VEGF). There was a strong correlation among interleukin-18 (IL-18), interferon-inducible protein-10 (IP-10), interleukin-1α (IL-1α), and interleukin-1β (IL-1β). However, eotaxin regulated upon activation of normal T cell expression and secreted factor (RANTES), which has their own independence. Conclusion: Idiosyncratic liver injury induced by ZGW has a strong positive correlation with MIP-1α and VEGF, which provides a new experimental evidence for clinical medication safety and risk prevention of ZGW.

OBJECTIVETo investigate the effect of Spearmint oil on inflammation, oxidative alteration and Nrf2 expression in rats with chronic obstructive pulmonary disease(COPD).

METHODSCOPD model was induced by intratracheal instillation of Klebsiella pneumonia and lipopolysaccharide (LPS) for 12 weeks in rats, and COPD rats were treated with Spearmint oil for 3 weeks. After COPD was induced, the pathological changes, changes in leucocyte number in blood and bronchoalveolar lavage fluid (BALF), MDA in lung homogenate and Nrf2 expression were observed. The effects of Spearmint oil on these changes were determined.

RESULTSpearmint oil 100 mg*kg(-1)significantly reduced leucocyte numbers in BALF, and attenuated bronchiolitis, pulmonary interstitial inflammation and inflammation cell infiltration. Spearmint oil 30-300 mg*kg(-1)decreased the destruction of pulmonary alveolus and the thickness of bronchioles walls, and inhibited goblet cell proliferation. Spearmint oil significantly reduced MDA in lung homogenate, and decreased the expression of Nrf2 protein in lung tissues.

CONCLUSIONSpearmint oil has protective effect on lung injury in COPD rats, since it improves pulmonary inflammation,oxidative alteration, and enhances Nrf2 protein expression.

OBJECTIVETo investigate the effect of synthetic drug QTY06 on chronic airway inflammation and mucoprotein expression induced by intratracheal (i.t) instillation of lipopolysaccharide (LPS).

METHODSChronic airway inflammation was induced by i.t instillation of LPS in rats. Phospholipids content and the number of leucocytes in bronchoalveolar lavage fluid (BALF), pathological and immunochemical changes were examined 3 weeks after LPS instillation. The effect of QTY06 on chronic airway inflammation was observed.

RESULTAfter treatment with QTY06, phospholipids in BALF was significantly increased, and the percentages of neutrophils and lymphocytes were decreased as well as the total number of leucocytes. Compared with the model group, pathological examination showed that tracheitis, bronchitis and pulmonary interstitial inflammation in QTY06 groups were significantly attenuated; epithelial damage was alleviated, infiltration of inflammatory cells reduced and the number of goblet cells decreased. QTY06 significantly decreased MUC5ac expression in trachea and bronchiole epithelium, and reduced the optical density and mucins area (%) as detected by image analysis in rats with chronic airway inflammation.

CONCLUSIONQTY06 can reduce and inhibit the chronic airway inflammation induced by LPS in rats, and increase the content of phospholipids in pulmonary surfactant and inhibit the hypersecretion of airway mucins.

OBJECTIVETo investigate the association of surgical skills, anhepatic time and preoperative hepatic function grading with bacteria infection after the liver transplantation and identify the common bacterial flora involved for effective prevention and treatment of the posttransplant bacterial infection. METHODS;The clinical records of 31 cases of liver transplantation from August 2004 to August 2005 were reviewed and the collected data were analyzed statistically. RESULTS; Among the 31 cases, posttransplant bacterial infection occurred in 16 cases accounting for a total incidence of 51.61%, with the incidence of multi-system (or multi-organ) infection of 22.58%. The earlier cases had longer average surgery time and anhepatic period than the later cases, with also higher incidence of infection. Among the 19 patients with hepatic function class A before surgery, 7 acquired bacterial infection involving one system or organ, 2 had infections compromising multiple system or organ. In the 8 patients of hepatic function class B before surgery, 2 had single-system or -organ infection and 1 multi-system or -organ infection. Four out of the 5 patients with hepatic function class C before surgery acquired posttransplant bacterial infections, all involving multiple systems or organs. Pseudomonas aeruginosa was the most common bacteria responsible for the infections in these cases.

CONCLUSIONImprovement of surgical skills can obviously reduce the incidence of bacterial infection after liver transplantation. No evidences suggest the correlation between the incidence of infections (including severe ones) and hepatic function class A or B before the operation, whereas patients with preoperative hepatic function class C seems to be at higher risk for infection involving multiple systems or organs. The anhepatic time does not significantly impact on the incidence or severity of the posttransplant infections, and Pseudomonas aeruginosa is the most common bacteria causing the infections.

OBJECTIVETo investigate the value of urgent colonoscopy in the diagnosis of severe acute lower gastrointestinal bleeding and the optimal bowel preparation before examination.

METHODSThe clinical data were collected from 188 patients undergoing wither urgent or elective colonoscopy for severe acute lower gastrointestinal bleeding in Nanfang Hospital. Univariate analysis was used to assess the effect of the timing of colonoscopy on the diagnostic rate of hemorrhage, and a multivariate model which stratified bowel cleanliness was used to analyze the impact of bowel cleanliness on the diagnostic rate of urgent colonoscopy.

RESULTSOf the 188 patients, 118 underwent urgent colonoscopy and 70 underwent elective colonoscopy examinations. The diagnostic rates were comparable between the two groups (44.1% vs 41.4%, P=0.724), but urgent colonoscopy resulted in a significantly higher diagnostic rate for identifying the bleeding source (32.2% vs 18.6%, P=0.041). The proportion of the patients taking oral laxatives was significantly lower in urgent colonoscopy group (P<0.001). Oral laxatives versus enema resulted in good, moderate, and poor bowel cleanliness in 63.6% vs 13.5%, 28.6% vs 24.3%, and 7.8% vs 62.2% of the patients (P<0.001). Univariate analysis indicated that good bowel cleanliness was associated with a significantly higher diagnostic rate of colonoscopy than poor bowel cleanliness (P=0.012). Multivariate analysis showed that with good bowel cleanliness, urgent colonoscopy yielded a significantly higher diagnostic rate than elective colonoscopy (P=0.030); subgroup analyses suggested that good bowel cleanliness improved the diagnostic rate of urgent colonoscopy as compared with poor bowel cleanliness (P=0.015).

CONCLUSIONIn patients with good bowel cleanliness, urgent colonoscopy yields a higher diagnostic rate than elective colonoscopy for severe acute lower gastrointestinal bleeding. Poor bowel cleanliness resulting from bowel preparation by enema significantly lowers the diagnostic performance of urgent colonoscopy. Oral laxatives are recommended over enemas for bowel preparation before urgent colonoscopy when the patients have stable hemodynamics.
