1.Progress in the development of antineoplastic activity substance from marine sponge
Journal of International Oncology 2006;0(10):-
Marine organism is important source of antineoplastic active substance,sponge is the secondly larger amount of organism source besides coral in the ocean. In recent decade, several high antineoplastic active substances with novel structure are abstracted and identified from different kinds of sponges. These discovers reveal bright prospect of research and development. This article summarized antineoplastic active sponge abstracts and their synthesis derivative which still in the clinical trials,their origins and the research development of their chemical composition and pharmacological action.

OBJECTIVE To investigate the effect of norepinephrine (NE) on expression of interleu?kin-6 (IL-6) in human macrophages and explore its pro-inflammatory and pro-atherosclerotic mecha?nisms. METHODS Murine U937 macrophages were cultured and stimulated with 0.01-10μmol·L-1 of NE for 6, 9, 12, 24 and 48 h. The IL-6 mRNA level of 24 h was analyzed by RT-PCR, and IL-6 protein expression in the supernatant at 0, 6, 9, 12, 24 and 48 h was detected by ELISA. After 24 h, intracellular reactive oxygen species (ROS) generation was observed by DCF fluorescence. The cells were pretreated with antioxidant N-acetylcysteine (NAC), complexⅡinhibitor thenoyltrifluoroacetone (TIFA) and NADPH oxidase inhibitor diphenyleneiodonium (DPI) for 1 h, and stimulated with different concentrations of NE for 24 h, before the level of IL-6 protein was detected by ELISA. RESULTS The expression of IL-6 mRNA and protein increased with the concentration NE 0.01-10 μmol · L-1 and incubation time. IL-6 mRNA and protein levels in macrophages were 2.62 and 4.47-fold those in cell control group when treated with NE 1.0μmol·L-1 for 24 h. Meanwhile, as the concentration of NE increased, the generation of ROS was 1.87, 2.56, 2.91 and 5.36-fold that of cell control group (P<0.01). NAC 10 mmol · L-1 and DPI 10 μmol · L-1 significantly antagonized the effect of NE on IL-6 expression, but TIFA had no effect. CONCLUSION NE upregulates IL-6 expression, which may contribute to the formation and develop?ment of atherosclerosis via ROS mediated by NADPH oxidase in macrophages.

Objective To assess the value of serum N terminal pro-brain natriuretic peptide(NT-Pro-BNP) in the diagnosis of congestive heart failure(CHF) and evaluation of cardiac function in children with ventricular septal defect (VSD).Methods Fifty one children were enrolled from March 2004 to March 2005.NT-Pro-BNP was measured by enzyme immunoassay technique.At the same time,left ventricular ejection fraction(LVEF) and left ventricular shortening fraction(LVFS) were detected with echocardiography.Results The data of NT-Pro-BNP were showed but the logarithms of which were normal distribution.The values of NT-Pro-BNP were developed successively along with the severity of cardiac function.But there was no difference between the group of no heart failure and mild heart failure.But the values of LVEF and LVFS had no differences in the control,the mild and the moderate heart failure and the same time all of which beyond the standard of diagnosing heart failure.NT-Pro-BNP could reflect the degree of heart failure or cardiac function (r=0.826).But LVEF and LVFS can not reflect the degree of the cardiac function.Conclusions NT-Pro-BNP can reflect the degree of the cardiac function in VSD,and the degree of the heart failure can be classed by the levels of serum NT-Pro-BNP.But the value of LVEF and LVFS can not reflect the degree of the heart failure in the same disease.

AIM: To evaluate visual acuity outcomes after phacoemulsification and intraocular lens implantation in patients with wet age-related macular degeneration (wAMD).METHODS: We reviewed the medical documents of the patients who underwent phacoemulsification and intraocular lens implantation surgery during June 2013 and January 2016.Totally 61 eyes of 48 patients with wAMD in the stable stage were recruited.The pre-and post-operative vision of selected cases were recorded and compared.RESULTS: After phacoemulsification and intralocular lens implantation, visual acuity changes were as follows: 49 eyes improved, 11 eyes retained, and 1 eye deteriorated.Visual acuity improvement after cataract surger were statistically significant (P<0.001).Visual acuity improvement was not related to age.CONCLUSION: Visual acuity improved in patients with wet AMD after phacoemulcification and intraocular lens implantation.

Objective To detect genetic polymorphism of Toll like receptor 2 (TLR2) R753Q and Toll like receptor 4 (TLR4) D299G and T399I ,and to analyze its role and mechanism in the occurrence and development of colorectal carcinoma .Meth‐ods Totally 256 cases of patients with colorectal carcinoma and 256 cases of healthy control individuals were collected .The geno‐types of TLR2 R753Q ,TLR4 D299G and TLR4 T399I were detected by using PCR‐RFLP method .The levels of IL‐1α,IL‐8 ,MIP‐1αand MCP‐1 protein were detected by using ELISA .Results It is shown that TLR4 T399I was associated with the risk of color‐ectal cancer .The frequency of CT combined TT genotype of T399I in case group and control group was 31 .2% and 18 .7% ,respec‐tively .The frequency of T allele in case group and control group was 18 .2% and 10 .2% ,respectively ,and difference was statistical‐ly significant(P<0 .05) .Individuals with T allele of T399I showed a 2 .534‐fold increase in colorectal cancer risk compared with the T399I C allele(95% CI:1 .462-2 .734 ,P<0 .01) .There were significant differences in the expression levels of IL‐1αand MCP‐1 in colorectal carcinoma tissues of different genotypes .The expression level of IL‐1α in patients with CT combined TT genotype of T399I and those with CC genotype was (36 .97 ± 21 .43) and (22 .27 ± 17 .89)pg/mg respectively ,and the expression level of MCP‐1 was (24 .57 ± 17 .74) and (12 .91 ± 9 .78)pg/mg respectively .Conclusion T399I TLR4 is associated with the occurrence and de‐velopment of colorectal carcinoma ,and the risk of colorectal carcinoma in individuals with T genotype is significantly increased ,in which monitoring the expression of IL‐1 and MCP‐1 in colorectal carcinoma tissues might be the mechanism .

Objective To explore the effect of comprehensive management of cardiac rehabilitation on the quality of life of patients after percutaneous coronary intervention(PCI). Methods A total of 60 patients with PCI were randomly divided into the rehabilitation group and the control group with 30 cases each by convenience sampling method. The control group received routine treatment and nursing care of postoperative PCI, and the rehabilitation group received cardiac rehabilitation management on the basis of the control group, including training guidance, management of double heart psychological intervention, nutritional intervention diet guidance, evidence-based medicine, and set up system etc. The Hospital Anxiety and Depression Scale(HADS) score, 6 minutes walking distance (6MWD), coronary heart disease risk factors and Seattle Angina Score (SAQ score) were observed at 6 months after PCI. Results HADS score anxiety rate, depression rate, anxiety and depressive state at 6 months after PCI was 10.0%(3/30), 10.0%(3/30), 0 respectively in the rehabilitation group, and 33.3%(10/30), 36.7%(11/30), 13.3%(4/30) in the control group respectively, and there was significant difference between 2 groups (χ2=4.504, 5.963, 1.071. all P<0.05). 6MWD was (451 ± 48) m in the rehabilitation group and (402 ± 42) m in the control group, and there was significant difference between 2 groups (t=6.155, P=0.022). Compared two groups of coronary heart disease risk factors control level: there was significant difference in total cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol, glycosylated hemoglobin, body mass index, systolic pressure, diastolic pressure(t=-2.927-5.981, P<0.01 or 0.05). SAQ score in physical limitation, angina stability , angina pectoris, treatment satisfaction, disease awareness scores were (73.79 ± 6.04), (80.35 ± 7.63), (75.31 ± 8.11), (80.23 ± 5.44), (76.59 ± 14.29) points in the rehabilitation group, and (53.19 ± 5.13), (65.87 ± 18.85), (64.41 ± 6.31), (70.49 ± 8.01), (45.83 ± 8.65) points in the control group, there were significant differences between 2 groups (t=-21.630-18.959, all P<0.01). Conclusions The comprehensive management of cardiac rehabilitation alleviates the anxiety and depression of patients after PCI, reduces the risk factors of coronary heart disease, and improves the exercise ability and quality of life.
