OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.

AIMTo observe protective effects of safflower injection (SI) on lung ischemia/reperfusion injury (LIRI) and investigate its potential mechanism.

METHODSRabbit lung model of ischemia/reperfusion injury was constituted in vivo. The rabbits were randomly divided into three groups: sham-operation group (S group), ischemia/reperfusion group (I/R group) and ischemia/reperfusion plus safflower injection group (SI group). Malondialdehyde (MDA) content, superoxide dismutase (SOD) and xanthine oxidase (XO) activities in serum were measured. The lung tissue sampled at the end of the experiment was assayed for wet/dry weight ratio (W/D), injured alveoli rate (IAR) and ultrastructural changes were observed under electron microscope. The expression of COX-1 and COX-2 were measured by immunohistochemistry (IHC). The expressions of COX-1mRNA and COX-2mRNA were observed by in situ hybridization (ISH).

RESULTSIn I/R group, XO and MDA increased and SOD decreased in serum, while the same changes happened in SI group but less severely(P<0.01). The value of W/D and IAR was much higher in I/R group than S group, but decreased in SI group. Electron microscope showed obvious ultrastructural injury brought by LIRI in I/R group, which was greatly attenuated in SI group. The IHC and ISH demonstrated that COX-2 and COX-2mRNA in pulmonary tissue of I/R group were significantly higher than those of SI group (P < 0.01). The difference of COX-1 and COX-1mRNA in pulmonary tissue among the three groups was not significant.

CONCLUSIONThe ischemia/reperfusion lung injury insults induced the regulation of COX-2 in lung. Safflower injection may attenuate lung ischemia/reperfusion injury through inhibiting cyclooxygenase-2 expression.

AIMTo observe protective effects of polydatin (PD) during lung ischemia/reperfusion injury (LI/RI) and investigate its potential mechanism .

METHODSRabbit lung model of ischemia/reperfusion injury was constituted in vivo. The 40 rabbits were randomly divided into four groups (n = 10): control group (C group), ischemia/reperfusion group (I/R), PD + I/R group (PD) and PD+ polymyxin B (PMB) + I/R group (PMB). The blood specimen gathered at different time points were tested for the content of melondialdehyde (MDA) and the enzyme activity of superoxide dismutase (SOD). The lung tissue sampled at the end of the experiment were assayed for wet/dry weight ratio (W/D), injured alveoli rate (IAR) and observing ultrastructure changes under electron micro scope.

RESULTS(1) The activity of SOD showed a similar time-dependent decline in I/R group and PMB group during I/R, while in PD group this tendency was milder (P < 0.01 vs I/R group). (2) In contrast to the results above, the level of MDA markedly increased in I/R and PMB group, but was slowed down in PD group (P < 0.01 vs I/R group). (3) The value of W/D) and IAR was much higher in I/R and PMB group (P < 0.05 or P < 0.01 vs C group). In PD group, it was decreased (P < 0.01 vs I/R group or PMB group). (4) Electron microscope showed obvious ultrastructure injury brought by LI/RI in I/R group and PMB group, which was greatly attenuated in PD group.

CONCLUSIONPD can protect lung from LI/RI, and PKC may participate in its mechanisms.

Objective: The current study was designed to evaluate the clinical application of radioimmunoimaging(RII) for lymph node metastasis in esophageal carcinoma. Methods:1)131I was used to label McAb G9(specific to cellular membrane antigen of human esophageal carcinoma) and form labeling compound 131I-G9. Administration of 131I-G9 in esophagus submucosally with a specific injector for the purpose of submucosal injection via endoscopies in preoperative patients with squamous cell carcinoma of thoracic esophagus followed by RII. 2)The samples of dissected lymph node were used for detection of radioactivity. Results: 1)The pictures at 48 h showed that small radioactivity concentrated dots appeared dispersedly in mediastinum and upper abdomen around esophagus and cardiac gastric. The lymph nodes were considered metastatic in above regions. 2)The pathological results of the lymph nodes dissected compared to the RII result. The metastatic lymph nodes were found in the regions of dispersedly concentrated radioactivity, while no metastatic lymph nodes could be found in the radioactivity free regions. 3)After counting for radioactivity, lymph node metastases showed higher antibody uptake than the non-metastases lymph nodes. The difference was statistically significant. Conclusion: 131I-G9 may be used to locate metastatic lymph nodes in patients with esophageal carcinoma.

BACKGROUNDGastric varices (GV) are life-threatening for patients with portal hypertension. Endoscopic injection with butyl cyanoacrylate (BC), the mainstay of the therapy for GV, has been reported to be effective for hemostasis of bleeding varices, but its efficacy in the obliteration of GV and impact on the survival of patients still needs clarification. Here we summarized our experience of 10 years' practice to evaluate the efficacy and safety of endoscopic therapy using BC for GV patients.

METHODSFrom January 1997 to April 2006, GV cases treated with endoscopic injection using BC were collected. The "sandwich method" and the "modified sandwich method" were used to inject BC intravascularly. Retrograde analysis was made on the data of treatment and follow-up.

RESULTSA total of 635 GV cases treated with endoscopic injection using BC were collected, most of them (90.2%) suffered from post-hepatitis cirrhosis. Emergency hemostasis was achieved in 139 out of 146 sessions (95.2%). Complications occurred in 32 cases (5.2%), including hemorrhage due to early expulsion of tissue glue (3.1%), septicemia (1%) and ectopic thrombosis (0.5%), such as spleen infarction. Endoscopic follow-up in 503 patients showed complete disappearance (76.9%), collapse (17.3%) or remnants (5.8%) of gastric varices. A total of 550 patients were followed up clinically for 3 to 115 months. Of these patients, 44 had recurrent bleeding (8.0%) and 44 died from hepatic failure, recurrent bleeding, hepatic carcinoma or other causes. The longest survival was 115 months, with a median survival of 25 months. Survival rates at 1, 2, 3, 4 and 5 year were 95%, 92%, 90%, 83% and 81%, respectively.

CONCLUSIONSEndoscopic sclerotherapy with BC is effective for the hemostasis of bleeding GV, as well as obliteration of GV which contributes to less rebleeding and better survival. The modified sandwich method may be useful to minimize ectopic embolism, which we speculated to result from excess iodized oil.

OBJECTIVETo study the effect of rosiglitazone on atherosclerosis and potential mechanism in ApoE-knockout mice.

METHODSThirty-two 6-week-old ApoE-knockout mice were used as atherosclerosis model in two groups: rosiglitazone group (n = 18) and control group (n = 14). Each group contained equal numbers of male and female mice. All mice were fed with normal chow diet. In addition to normal diet, rosiglitazone group received rosiglitazone 17 mg/kg of body weight/day. Venous bloods were collected for plasma glucose and lipid analysis, and aorta were prepared for morphologic and immunohistochemical analysis after 14 weeks. Aortic root (1 cm) was cut and prepared for paraffin slice. The histomorphometric analysis of atherosclerotic lesion was performed by means of HE; positive percentage of macrophage cell and tumor necrosis factor-alpha were measured by means of immunohistochemistry in cross section. The ratio of lesion/aortic wall surface in the rest aorta was measured by means of Sudan IV staining in longitudinal section.

RESULTSThe amount of fatty streak in rosiglitazone group was significantly greater than that of control group; the gross number of lesions and the number of fibrous plaque and atheromatous plaque were similar in two groups. There were no differences in percentage of lesions in cross section in two groups. Rosiglitazone could significantly reduce the extend of atherosclerosis of longitudinal section, decrease the amount of macrophage cell and the level of tumor necrosis factor-alpha in lesions. The plasma glucose was normal and similar in two groups, and total cholesterol, LDL-cholesterol and triglyceride were significantly higher in rosiglitazone group.

CONCLUSIONRosiglitazone suppresses the expression of tumor necrosis factor-alpha, reduces the number of macrophage cell in lesion, and inhibits the development of atherosclerosis.
