Objective To study the clinical pathological features, treatment and prognosis of umbilical metastases of colorectal carcinoma. Methods From January 2000 to September 2010, 10 umbilical metastases of colorectal carcinoma cases were admitted. The clinical features were reviewed. Results Four radical resection of colon cancer and resection of the umbilical plexus metastases cases with chemotherapeutic intraperitoneal perfusion lived 9,11,14 and 18 months respectively, 1 ileum-transverse colon anastomosis case with chemotherapeutic intraperitoneal perfusion lived six months, 2 patients with systemic widely transfer and umbilical transfer with pure venous chemotherapy lived 3, 3.5 months respectively, 3 colon intra-operative cases with venous chemotherapy lived 5 ,5. 5 and 7 months respectively. Conclusion Surgical resection of the primary focal and periumbilical metastases can prolong survival time with adjunctive therapy.

Objective To investigate the effects of benazepril on the expression of receptors for advanced glycation end-products(RAGE)in diabetic rat kidneys,and to explore its mechanisms of renal protection in diabetic rats. Methods Thirty SD rats were randomly divided into three groups(n=10 in each group): normal control group,diabetic control group and diabetic with benazepril group.Blood glucose,blood lipid,HbA1c,kidney to body weight ratio and 24 h urinary protein excretion were detected after 12 weeks.RAGE mRNA level was analyzed by quantitative RT-PCR. Results Compared with the normal control group,the blood glucose,HbA1c,triglyceride,total cholesterol and low density lipoprotein cholesterol in the diabetic control group and diabetic with benazepril group were significantly increased(P0.05).The kidney to body weight ratio,24 h urinary protein excretion and RAGE mRNA level in the diabetic with benazepril group were significantly higher than those in the normal control group(P

Objective To investigate the effects of valsartan on the expression of receptors for advanced glycation end-products(RAGE) in kidneys of diabetic rats,and to explore its renoprotection mechanisms. Methods Thirty rats were divided into normal control group,diabetes control group and diabetes with valsartan group(n=10).Blood glucose,blood lipid,HbA1c,kidney to body weight ratio and 24 h urinary protein excretion were measured after 12 weeks.RAGE mRNA level was detected by real-time quantitative PCR. Results Compared with normal control group,kidney to body weight ratio,24 h urinary protein excretion and RAGE mRNA were significantly increased in diabetes control group.Compared with diabetes control group,kidney to body weight ratio,24 h urinary protein excretion and RAGE mRNA were significantly decreased in diabetes with valsartan group. Conclusion Valsartan can inhibit renal hypertrophy and decrease urinary protein excretion in diabetic rats.The renoprotective effects may be related to its inhibition on RAGE expression.

Objective To propose a decision tree-based early warning model so as to predict the medical equipment quantity and quality under special conditions to quantize maintenance and detection staffs allocation,components supply,emergency planning and etc.Methods A data set was established based on the verification report,data on performance parameters detection and daily management log,and then underwent pretreatment.A decision tree came into being with the algorithms of ID3,CHAID and etc.The data rule corresponding to the decision tree was transformed into a series of early warning information.The model was verified by applying it to medical equipment usage management.Results The decision tree developed was applied to analyzing a vehicle-mounted water purifying device maintenance and usage records in some logistics support vehicle,and it's found the main factors contributing to the failures included migration distance along non-paved road,ambient temperature and service time.Conclusion The decision tree-based early warning model for medical equipment quantity and quality gains high feasibility and practical values.

A sesquiterpene synthase (AsSS4) full-length open reading frame (ORF) cDNA was cloned from wounded stems of Aquilaria sinensis by RT-PCR method. The result showed that the ORF of AsSS4 was 1,698 bp encoding 565 amino acids. Prokaryotic expression vector pET28a-AsSS4 was constructed and transformed into E. coli BL21 (DE3) pLysS. Recombinant AsSS4 protein was obtained after induction by IPTG and SDS-PAGE analysis with a MW of 64 kD. Enzymatic reactions using farnesyl pyrophosphate showed that recombinant AsSS4 protein purified by Ni-agarose gel yielded five sesquiterpene compounds, cyclohexane, 1-ethenyl-1-methyl-2, 4-bis(1-methylethenyl)-, β-elemene, α-guaiene, α-caryophyllene and δ-guaiene. This paper reported the first cloning and functional characterization of AsSS4 gene from A. sinensis, which will establish a foundation for future studies on the molecular mechanisms of wound-induce agarwood formation in A. sinensis

Objective To investigate the effect of histone deacetylase inhibitor trichostatin A (TSA) on the chemotherapy sensibility of 5-fluorouracil (5-Fu) in colorectal cancer cell line Lovo, and to explore the possible mechanisms.Methods According to the treatment methods, the cells were divided into control group, 5-Fu group, TSA group, TSA preconditioning group and combination group (TSA+5-Fu).MTT assay was used to detect cell proliferation at 24 h, 48 h and 72 h after drugs treatment.Transwell assay was used to test cell invasion after 24 h drugs treatment.Flow cytometer was applied to observe the apoptosis after 24 h drugs treatment.The expressions of thymidylate synthase (TS) were detected by Western blot after 24 h drugs treatment.Results Compared with control group, the 5-Fu group, TSA preconditioning group and combination group had a growth inhibition to Lovo cell at 24 h, 48 h and 72 h (P ＜ 0.05), and compared with 5-Fu group, the growth inhibition of TSA preconditioning group and combination group were distinctive at 48 h and 72 h (P ＜ 0.05).However, the inhibition between TSA preconditioning group and combination group were no significant (P ＞ 0.05).Interfered after 24 h, the number of cells penetrating the matrigel in control group, 5-Fu group, TSA group,TSA preconditioning group and combination group were (25.0±4.2), (16.8±2.8), (19.6± 2.5), (8.2±3.2) and (6.5±2.6), respectively (P ＜ 0.05), and the apoptosis rates were (4.26±1.36) ％, (11.66± 3.18) ％, (8.57±2.69) ％, (39.79±8.53) ％ and (45.18±10.07) ％, respectively (P ＜ 0.05).Compared with control group, the number of cells penetrating the matrigel in the experimental groups was significantly decreased, and the apoptosis rate was significantly increased (P ＜ 0.05).Compared with 5-Fu group, the numbers of cells penetrating the matrigel in TSA preconditioning group and combination group were markedly decreased, and the apoptosis rates were markedly increased (P ＜ 0.05), but the number of cells penetrating the matrigel and the apoptosis rate between TSA preconditioning group and combination group were not different (P ＞ 0.05).The difference of TS expression between control group and 5-Fu group was not significant (P ＞ 0.05).Compared with that in control group and 5-Fu group, TS expressions in TSA group, TSA preconditioning group and combination group were markedly decreased (P ＜ 0.05), but TS expressions among the last three groups were not different (P ＞ 0.05).Conclusion TSA can increase the chemotherapy sensibility of 5-Fu in Lovo cells, which may be dependent on reducing the TS expression.

Objective To investigate the expression of the enhancer of zeste homolog 2 (EZH2) gene and its significance in colorectal adenocarcinoma.Methods Immunohistochemistry and Western blot was used to assess the expression of EZH2 in human colorectal adenocarcinoma tissues,colorectal adenoma tissues and non-cancerous adjacent colorectal tissues.The relationships between EZH2 and each clinical pathology parameter were analyzed.Results The results of immunohistochemical trail showed that the expression rates of EZH2 in colorectal adenocarcinoma,colorectal adenoma and non-cancerous adjacent colorectal tissues were 80.56 ％ (87/108),62.5 ％ (25/40) and 5.00 ％ (2/40),respectively (P ＜ 0.05).Western blot revealed that the expression level of EZH2 in colorectal adenocarcinoma tissues,colorectal adenoma tissues and non-cancerous adjacent colorectal tissues level 0.549±0.145,0.283±0.023 and 0.107±0.022,respectively.The level in colorectal adenocarcinoma tissues (0.549±0.145) and colorectal adenoma (0.283±0.023) was significantly higher than that in non-cancerous adjacent colorectal tissues (0.107±0.022).Compared with colorectal adenoma tissues,level in colorectal adenocarcinoma tissues was significantly higher.There were significant differences among the three groups (F =20.113,P ＜ 0.05).The ratio of high expression level of EZH2 in colorectal adenocarcinoma tissues was closed related with tumorgenesis,differentiation,TNM staging and lymphatic metastsis (all P ＜ 0.05).However,no correlation was revealed between EZH2 expression and the age,gender (both P ＞ 0.05).Conclusion The expression of EZH2 may be associated with the tumorgenesis invasion,metastasis and progression of colorectal adenocarcinoma.
