ABSTRACT

Objective:To study the relationship of macrophage migration inhibitory factor(MIF)/activator protein-1(AP-1)/matrix metalloproteinase-9(MMP-9)expression with inflammatory response and coronary artery lesion(CAL)in Kawasaki disease(KD).Methods:Forty-six children with KD were enrolled as the KD group, and divided into CAL group( n=17)and non-coronary artery lesion(NCAL)group( n=29). Fifteen age-and gender-matched children with lower respiratory infections and twenty children for selective operation were chosen as the control groups.Fluorescence quantitative PCR and Western blot were used to detect c-Jun/c-Fos mRNA and protein expression respectively.Serum levels of MIF/phospho-c-Jun/MMP-9 were measured by ELISA. Results:The c-Jun/c-Fos mRNA and protein expression as well as phospho-c-Jun level increased significantly in acute phase of KD as compared with those in control groups(comparison between groups: c-Jun mRNA: F=654.318, P<0.001; c-Fos mRNA: F=580.998, P<0.001; phospho-c-Jun: F=74.756, P<0.001; all P<0.05), and they were even higher in the CAL group(c-Jun mRNA: t=6.820, P<0.001; c-Fos mRNA: t=8.047, P<0.001; phospho-c-Jun: t=2.361, P=0.029; all P<0.05), then decreased in subacute phase.Serum protein levels of MIF and MMP-9 in acute phase of KD were higher than those of control groups(comparison between groups: MIF: F=104.008, P<0.001; MMP-9: F=182.798, P<0.001), and much higher in CAL group than those in NCAL group(MIF: t=2.163, P=0.043; MMP-9: t=2.104, P=0.048). There were positive correlations among serum MIF, phospho-c-Jun and MMP-9 in acute phase of KD(MIF and phospho-c-Jun: r=0.552, P<0.001; phospho-c-Jun and MMP-9: r=0.731, P<0.001; MIF and MMP-9: r=0.421, P=0.004). Conclusion:MIF/AP-1/MMP-9 signaling pathway may participate in the pathological progress of KD vasculitis and CAL.AP-1 expression and activation level in acute phase may be helpful to assess the inflammatory status and to predict CAL.

ABSTRACT

Objective To observe the effects of Hedysari Polysaccharide (HPS) on the expressions of TSP-1 and PDGF-B in the retina of diabetic rats;To discuss the protective effect and possible mechanism on diabetic retinopathy. Methods The diabetic model was established by intraperitoneal injection of streptozotocin. 50 male SPF Wistar rats were randomly divided into 5 groups:model group, calcium dobesilate group, and HPS high-, medium-, and low-dose group, extra 10 rats were set as the normal group, 10 rats in each group. Each administration group was given relevant medicine for gavage, while model group and normal control group were given same amount NS for gavage, once a day for 8 weeks. The mRNA and protein expression of TSP-1 and PDGF-B were detected by qRT-PCR and immunohistochemistry. The retinal structure was observed by HE staining. Results HE staining showed that each layer of the retina of the model group was clear and complete, but the outer nucleus layer became looser, thinner and more disorderly, and the number of ganglion cells decreased slightly; the administration groups were improved markedly compared with the model group. Compared with the normal control group, the mRNA level and protein expression of retina TSP-1 on the model group dramatically dropped (P<0.01), and those of PDGF-B strikingly increased (P<0.01);Compared with the model group, the mRNA level and protein expression of retina TSP-1 on alladministration groups rose (P<0.05, P<0.01), and those of PDGF-B went down (P<0.01); Compared with all other administration groups, there was statistical significance in the mRNA level and protein expression of retina TSP-1 and PDGF-B on HPS high-dose group (P<0.05, P<0.01). Conclusion HPS may prevent the angiogenesis and proliferation in diabetic retinopathy process through adjusting the content of TSP-1 and PDGF-B in retina of diabetic rats so as to protect the retina.

ABSTRACT

Objective To evaluate CTP,MELD,MELD-AS,MELD-Na,i-MELD and MESO in prognosis of cirrhosis patients who underwent endoscopic injection sclerotherapy (EIS). Methods Seventy-eight cirrhosis patients with integral clinical and follow-up data were enrolled into the study. The area under the receiver operating characteristic (ROC) curve (AUC) was used to compare these six models in predicting mortality risk. The optimal threshold of them to determine the prognostic death risk was calculated by ROC curves. Results Eight patients died within half one year, 11 patients died within the first year. There was no significant difference in gender and age between the survival and death groups. The AUC of the six models higher than 0.800 were. that, 6-month: MELD-AS (0.837), MESO (0.830), MELD (0.830) ; 12-month: MELD (0.822),MELD-AS (0.821),MESO (0.814). Conclusions MELD-AS,MESO,MELD and so on are all accurate predictive systems for 6-month and 12-month of patients who underwent EIS. The value of them are very important in the selection of patients for EIS, and have a certain clinical significance.

ABSTRACT

Objective To evaluate the model of end-stage liver disease (MELD) and Child-Tur-cotte-Pugh (CTP) in prognosis for cirrhotic patients with massive hemorrhage from esophageal varieosis, who underwent emergency endoscopic sclerotherapy (EIS). Methods The clinical and follow-up data of a co-hort of 65 liver cirrhotic patients with massive hemorrhage from esophageal varicosis treated by EIS were ana-lyzed retrospectively. Correlation between MELD values and CTP score and classification was analyzed. The area under the receiver operating characteristic (ROC) curve was used to compare MELD with CTP score and classification in predicting mortality risk. The optimal threshold of MELD to determine the prognostic death risk was calculated by ROC curves. Results MELD, CTP score and classification correlated signifi-cantly with each other. Seven patients died within six months and 9 died within the first year of follow-up.There was no significant difference in gender, age and serum bilirubin between the survival and death groups, while the serum creatinine, international normalized ratio (INR), CTP score, and MELD score were significantly different. The areas under the ROC curve of MELD were both greater than 0.8 to predict 6-month and 1 -year survival, and also were greater than those of CTP score and classification. Areas under the ROC curve of MELD is superior to, but not significantly different though, CTP score or classification. The optimal threshold values of MELD and CTP score both showed satisfactory predicting accuracy of mortality risk. Conclusion MELD is an accurate predictive system for 6 months and 1 year in liver cirrhotic patients with massive hemorrhage from esophageal varicosis treated by EIS. The MELD value is very important in the selection of patients for E1S. But it is not more efficient than CTP score and classification.

ABSTRACT

Objective To investigate the treatment of intractable bile duct stones. Methods Of the total 149 cases of biliary stones, some are multiple bile duct stones,large stones,stones obstructed in the duodenal ampulla or residuary stones after T-tube surgery, others are associated with small papilla or papilla with neighoring diverticulum. All the stones were extracted with several endoscopic methods, such as choledochoscopy during or after operation, mechanical lithotripsy after EST(endoscopic sphincterotomy), biliary mother-baby endoscopy, ENBD(endoscopic nasobiliary drainage) or biliary-duodenum internal drainage. Results In general, extrahepatic bile duct stones were effectively removed in 94. 6% cases. In 19 out of 20 cases, stones were completely removed with choledochoscopy during operation; In 35 out of 40 cases stones were fully extracted through T-tube endoscopy, and in 72 of 76 cases stones were thoroughly removed with mechanical lithotripsy after EST. Conclusion The intractable bile duct stones can be effectively managed with combined endoscopic therapy, which is attributed to the high success rate in removing biliary stones and should be popularized in this field.
