Objective To investigate the relationship between the expression of T lymphoma invasion and (metastasis) inducing factor 1 (Tiam1), ras-related C3 botulinum toxin substrate 1 (Rac1) with the invasion and metastasis of gastric cancer. Methods The expressions of Tiam1 and Rac1 proteins in 60 cases of (gastric) cancer and paracarcioma gastric mucosa tissues were detected using Strept Avidin-Biotin Complex(SABC) immunohistochemical method,and the correlation between the expression of Tiam1, Rac1 and (clinicopathological) parameters of gastric cancer were analysed. Results (1)There was negative staining of Tiam1 protein in paracarcioma gastric mucosa tissues, while positive staining was detected in gastric cancer (tissues)(78.33%)(P 0.05). (4) The expression of Rac1 in patients with positive staining of Tiam1 was significantlyhigher than that in patients with negative staining(P

Objective To measure the fluorescence spectral information of UVRF in the facial skin of patients with acne vulgaris and seborrheic dermatitis and to comprehend the optical properties of UVRF.Methods The lesions were squeezed to extract the sebaceous secretions containing UVRF in the facial skin.Ocean Optics USB2000 +F02243 Spectrometer and the 308nm excimer laser were used as an excitation light source to measure the signal of the LIF spectrum of UVRF in 6 acne vulgaris and 4 seborrheic dermatitis patients' facial part,compared with protoporphyrin Ⅸ.Results 1-4 peaks were detected in 10 patients' UVRF specimen respectively.The fluorescence spectra's characteristic peak of UVRF in 10 patients was at 680 nm.Protoporphyrin Ⅸ was at 688 nm and more gentle and generous than UVRF's characteristic peak.Conclusions LIF system can be used to detect the fluorescence spectroscopy of UVRF.UVRF has similar spectral characteristics to protoporphyrin Ⅸ,but it is not the same species.

Objective To evaluate the effect of an equivalent uiform dose optimization (EUD) based optimization algorithm in sparing the organ at risk (OAR) of tumor treated with intensity-modulated radiation therapy (IMRT).Methods 10 patients of nasopharyngeal carcinoma (NPC),10 patients of esophagus cancer,6 patients of rectum cancer were randomly selected from all patients received IMRT treatment.Then physical optimization constraints (dose/dose-volume constraints) were designed as EUD optimization,while the physical objectives for targets and other OAR were unchanged.Results There was statistically significant difference in protecting OAR in 8 NPC patients of PLANED group compared with those of PLANNO_EuD group (t values were 2.590,2.352,3.656,2.148,2.283,3.683,2.192,2.353,2.146,2.276,2.126,P ＜ 0.05).There was no statistically significant difference in protecting OAR in 10 cases of esophageal cancer between PLANEUD group and PLANNO_EUD group (t value were 0.408,0.427,0.920,P ＞ 0.05).There was statistically significant difference in protecting OAR in 6 cases of rectum cancer of PLANED group compared with those of PLANNO_EUD group (t values were 2.332,2.693,2.279,2.244,P ＜ 0.05).Conclusion EUD optimization can reduce the doses to OAR which may be quite helpful to reduce the occurrence rate of OAR complications.

Background and purpose:As a regulatory factor of cytoskeletal structure,a close correlation existed between Tiam 1(T lymphoma invasion and metastasis inducing factor 1) and the invasion and metastasis of gastroenteric tumor.We aimed to observe the effects of Tiam 1 antisense oligodeoxynucleotides(Tiam 1 ASODN) transfection on the invasive and migratory potentials of gastric cancer cells in vitro and vivo.Methods:The higher invasive and migratory subgroup(MH) were separated from human gastric cancer cell line MKN-45(M0) by laminin adhesion method in vitro.Tiam 1 ASODN was transfected into MH cells with liposome,and the expression of Tiam 1 mRNA and protein was determined by RT-PCR and ELISA separately.Changes in the invasive and migratory potentials of MH cells in vitro and vivo after transfected with ASODN were observed by Boyden chamber test and inoculation into nude mice respectively.Results:The expression of Tiam 1 mRNA and protein in MH cells after transfected with 0.43 ?mol/L ASODN(0.162?0.018,0.982?0.119) was significantly lower than that of either Liposome-transfected cells(0.789?0.054,1.237?0.108),sense oligodeoxynucleotides(SODN)-Liposome-transfected cells(0.754?0.039,1.234?0.103) or No-transfected cells(0.801?0.065,1.290?0.182)(P

Objective To compare detection of STAT3 and CEA by nest RT-PCR and peritoneal lavage cytology examination(PLC) in predicting peritoneal micrometastasis in gastric carcinoma patients. Methods Peritoneal washings of 66 patients with gastric carcinoma and 12 patients with benign gastric diseases were collected to detect the mRNA level of STAT3 and CEA by nest RT-PCR.PLC were carried out by H-E staining.Results The positive rates of STAT3 mRNA and CEA mRNA in peritoneal washings were 43.9% and 48.5%,respectively.The positive rates of STAT3 mRNA and CEA mRNA were significantly higher than those of PLC(31.8%).The positive rates of STAT3 mRNA and CEA mRNA were concurrently increased with the depth of tumor invasion,TNM staging and pathogenesis.Conclusion Detecting STAT3 mRNA in peritoneal washings by nest RT-PCR can improve the sensitivity of free tumor cell detection in peritoneal washings,and may be used to predict peritoneal micrometastasis of gastric carcinoma.

Objective To investigate the anti-gastric cancer effects of dendritic cells tumor vaccine loaded with heat shock protein gp96 polypeptide complex. Methods Con A sepharose affinity chromatography and mono Q ion exchange chromatography were applied to purify gp96 polypeptide complex from gastric cancer tissues and DC was loaded with gp96 polypeptide complex to prepare tumor DC vaccine. Fluorescence-activated cell sorter (FACS) was used to detect surface molecules expression of dendritic cells. Enzyme-linked immunosorbent assay ( ELISA) was used to detect IL-10 and interferon-? (IFN-?) of the supernatant secreted by activated T lymphocytes and 51Cr release test was performed to evaluate the gp96 peptide specific CTL response. Results DCs derived from patient's peripheral blood mononuclear cells loaded with gp96 polypeptide complex had high express surface molecule of GD1? (79. 3 ?4. 1)% , CD80 (84. 3 ? 2. 4) % , CD83 (85. 7 ? 3. 2) % and HLA-DR( 83.4 ? 2. 9) %. The effector T lymphocytes induced by DCs vaccine loaded with gp96 polypeptide complex had rised killing effect to primary culture gastric tumourcells(58.47?10. 71)% when compared with SGC 7901 cells(23. 98 ?4. 16)%. The level of IFN-? (2875 ? 177.66 pg/ml) significantly increased and that of IL-10 (36 ? 6.72 pg/ml) decreased. Conclusion Autologous heat shock protein gp96 polypeptide complex/DC vaccine induces strong peptide complex specific CTL response with high specificity.

Objective To investigate the effect of butylphthalide on brain edema and the expression of phosphorylated myosin light chain in peri-infarct tissue in focal cerebral ischemic rats.Methods A total of 212 adult male Sprague-Dawley rats were divided into a sham operation group (n =12),a cerebral ischemia group (n =100),and a butylphthalide group (n =100) (40 mg/kg,1/day,gavage) according to the random number table.Both the cerebral ischemia group and the butylphthalide group were redivided into 6 h,12 h,1 d,3 d,and 7 d groups (n =20 for each time point).A rat model of focal cerebral ischemic model was induced by photochemical method; 2,3,5-triphenyl tetrazolium chloride (TTC) staining was used to detect infarct volume (n =5); wet-dry weight method was used to detect the water content in brain tissue (n =5);immunohistochemistry (n =5) and Western blot (n =5) were used to detect the protein expression of periinfarct cortical p-MLC.Results TTC staining showed that no infarcts were observed in the sham operation group.The infarct volumes at each time points in the butylphthalide group were significantly less than those at the same time points in the cerebral ischemia group (all P ＜0.05).Wet-dry weight method showed that the water contents in brain tissue in the cerebral ischemia group and the butylphthalide group were significantly higher than that in the sham operation group (all P ＜ 0.05),but the water contents in brain tissue at each time points in the butylphthalide group was significantly lower than those at the same time points in the cerebral ischemia group (all P ＜ 0.05).Both immunohistochemistry and Western blot showed that the expressions of peri-infarct cortical p-MLC in both the cerebral ischemia group and the butylphthalide group were upregulated significantly compared to the sham operation group (all P＜ 0.05),but the expressions of peri-infarct cortical p-MLC at each time points in the butylphthalide group was significantly lower than those at the same time points in the cerebral ischemia group (all P＜ 0.05).Conclusions Butylphthalide can be up-regulated by reducing the expression of p-MLC caused by cerebral ischemia and reduce cerebral edema,and then reduce the infarct volume,and thus play a neuroprotective effect.
