Epidemiologic evidence suggests that diabetes mellitus appears to be negatively associated with abdominal aortic aneurysm formation. Diabetes mellitus may affect the physiological characteristics of the aorta and reduce the prevalence, incidence and expansion rate of abdominal aortic aneurysm. But the impact of diabetes mellitus on the rupture, operative complication and clinical outcome of abdominal aortic aneurysm is unclear. Randomized controlled trials are needed before conclusions can be drawn on the link between development and expansion of abdominal aortic aneurysm and medicines for diabetes. This review aims to analyze updated evidence of the association between diabetes mellitus and abdominal aortic aneurysm.

We have observed the protective effects of indocin (IND), a potent inhibitor of pro-sglandins (PGs), on ototoxicity induced by furosemide (FU) using the synchronous recording technique of endocochlear potential (EP) and auditory action potential(AP) in guinea pigs. The FU group were found to have a mean decrease in EP of 65.1?5.6mV and AP amplitude 91.5?10.2%. In contrast, the animals in the FU+IND group had a much smaller reduction of EP(17.5 ?3.8mV) and AP amplitude(31.1?4.7%). The rate of return in EP and AP was much faster in the FU+IND group as compared with the other group. Our findings suggest that the ototoxicity of FU may be related to the mediation of PGs in the inner ear target tissues. IND can interrupt an increase in endogenous PGs in cochlear tissues triggered by FU injection by inhibiting the biological synthesis of PGs, thus effectively diminishing the ototoxicity induced by FU.

Objective To evaluate the effects of different surgical treatments on polycystic hepatic disease and multiple simple hepatic cysts.Methods A total of 35 cases of polycystic hepatic disease and 54 cases of multiple simple hepatic cysts were surgically treated in our department from Jan.1998 to Jan.2006.Of the 35 cases of polycystic hepatic disease,12 were treated with the partial hepatic resection in combination with cyst fenestration,18 with laparotomic fenestration,5 with laparoscopic fenestration.Of the 54 cases of multiple simple hepatic cysts,6were treated with percutaneons aspiration and instillation of sclerosing agents (ethanol) under the guidance of ultrasonography B,36 with laparotomic fenestration,13 with laparoscopic fenestration.The surgical outcome and longterm follow-up outcome were retrospectively analyzed.Results After treatment,all polycystic hepatic disease patients experienced relief of symptoms when discharged.And the follow-up for an average of 3.0 years showed that 2 patients developed recurrence after the partial hepatic resection in combination with cyst fenestration,8 after the laparotomic fenestration,5 after the laparoscopic fenestration.The recurring rates were 16.7%,44.4% and 100.0% ,respectively.However,all patients of multiple simple liver cysts cured.Conclusions The approach of partial hepatic resection in combination with cyst fenestration is the most effective treatment for polycystic hepatic disease.Liver transplantation can cure polycystic hepatic disease,and is the only effective approach for severe cases.Percutaneous aspiration under the guidance of ultrasonography B is only effective for relief of symptoms before operation.Laparoscopic fenestration should be applied with caution.Laparoscopic fenestration is the first choice for multiple simple hepatic cysts with clinical symptoms.

To study the effectiveness of gene therapy for acoustic trauma induced by intensive noise, the replication defective adenovirus that carries human neurotrophin 3 cDNA(Ad NT3) was inoculated into the guinea pig cochlea 3 days after exposure. ABR and CAP were recorded after 14 days and 2 months, respectively. No difference was found 14 days after exposure. At the end of two months, the Ad NT3 treated animals showed less ABR threshold shift, lower CAP threshold and shorter CAP N1 latency by 100dBSPL click. The result suggested that Ad NT3 could be used to express the neurotrophins within the cochlea and reduce noise induced hearing loss in vivo .

Objective:To investigate the anti-proliferation effect of carvacrol on human gastric cancer cell BGC-823 and explore the molecular mechanism. Methods:The proliferation of BGC-823 cells was evaluated by MTT assay. Flow cytometry was used to ana-lyze the cell apoptosis after exposed to carvacrol. Transwell assay was used to analyze the effect of carvacrol on cell metastasis. Quanti-tative realtime-PCR was used to detect the expression of MMP-9 and TIMP-1. The expression of caspase-9 and PARP,and the activa-tion of ERK and P38 were detected by Western blot. Results:The incubation with carvacrol resulted in a significant inhibition of BGC-823 cell proliferation. After the treatment with carvacrol,the apoptotic rate was significantly increased( 0 μmol · L-1 vs 10 μmol · L-1 ,P<0. 000 1;0 μmol·L-1 vs 20 μmol·L-1 ,P<0. 000 1;0 μmol·L-1 vs 40 μmol·L-1 ,P<0. 000 1;0 μmol·L-1 vs 80μmol·L-1 ,P<0. 000 1)and the invasion ability was decreased(0 μmol·L-1 vs 80 μmol·L-1 ,P<0. 000 1). The expression of caspase-9(0 μmol·L-1 vs 80 μmol·L-1,P<0. 000 1)and TIMP-1 was increased(P<0. 000 1),PRAP fragment occurred(P<0. 000 1)and P38 signaling pathway was activated in the carvacrol treated group,while the expression of MMP-9 activity of ERK signa-ling pathway was inhibited(P<0.000 1). Conclusion:Carvacrol can inhibit cell growth and invasion,and induce cell apoptosis, which is closely related to MAPK signaling pathway.

BACKGROUND: The expression of Fas antigen and P53 protein in colorectal cancer could reflect the biological character and the prognosis of the tumor.OBJECTIVE: To investigate the relationship between the expression of Fas antigen and P53 protein in coloreetal cancer and the tumor-related biological characters.DESIGN: A controlled experiment by introducing pathological specimens as subjects.SETTING: The study was conducted in the Department of Pathology of Xijing Hospital Affiliated with the Fourth Military Medical University of Chinese PLA.PARTICIPANT S: Totally 32 pathological specimens of colorectal cancer were randomly selected from the Department of Surgery of Xijing Hospital between January 1995 and October 1998. Sixteen normal large intestine tissues were selected form the cadaver of pathology department.METHODS: The expression of Fas antigen and P53 protein in 32 colorectal cancer tissue and 16 normal intestine tissue were tested and compared with immunohistochemical method.MAIN OUTCOME MEASURES: Fas antigen and P53 protein expression in coloreetal cancer and normal intestine, and the clinical indicators of patients with colorectal cancer.RESULTS: The expression of Fas antigen was positive in normal large intestine tissue while the expression of P53 protein was negative. The positive rate of Fas antigen expression in colorectal cancer was 41% (13/32), while the positive rate of P53 expression in colorectal caner was 53% (17/32). Fas antigen significantly decreased in colorectal cancer tissues. The expression of Fas antigen was correlated with the histological type of colorectal cancer and its liver metastasis( P ＜ 0.05) . And the expression of P53 protein was correlated with the liver metastasis of colorectal cancer( P ＜ 0. 05).CONCLUSION: The expression of Fas antigen significantly decreases in colorectal cancer. The higher the malignance is, the more significant less the expression is. Fas antigen does not express in liver metastasis patients. P53protein had positive expression in colorectal cancer tissues, especially in patients with liver metastasis. The reduction and deletion of Fas antigen expression and the excessive expression of P53 protein indicate poor prognosis.
