Objective To investigate the expression of nuclear factor kappa B (NF-κB),tumor necrosis factor α (TNF-α) and interleukin6 (IL-6) in human colorectal carcinoma tissues,and to explore their clinical significances in the genesis and development of colorectal cancer.Methods Sixty cases of colorectal cancer tissues and 36 cases of colorectal adenoma tissues were collected,60 cases of paracancerous normal colorectal tissues were the controls.Immunohistochemistry SABC method was used to detect the expression of NF-κB,TNF-α and IL-6 in each group respectively.The correlation of NF-κB,TNF-α and IL-6 with clinical pathologic features of colorectal cancer was analyzed.Results In colorectal carcinoma,adjacent normal colorectal tissues and colorectal adenoma tissues the positive expression rates of NF-κB were 76.7 ％ (46/60),46.7 ％ (28/60),83.3 ％ (30/36),the positive rates of TNF-α were 70.0 ％ (42/60),36.7 ％ (22/60),66.7 ％(24/36),the positive rates of IL-6 were 80.0 ％ (48/60),43.3 ％ (26/60),61.1％ (22/36).The differences were significant in each group (all P ＜ 0.05).The expression of NF-κB was closely associated with the expression of TNF-α and IL-6 respectively.In addition,the expression of NF-κB and TNF-α were correlated with vascular invaded,lymphnode metastasis and different stages.The expression of IL-6 was correlated with lymphnode metastasis and different stages.Conclusion The over expression of NF-κB and the downriver inflammation factors have close relationship with biological behaviors of colorectal cancer.It may be considered that the pathway of NF-κB play an important role in the genesis and development of colorectal cancer.

Objective To observe the clinical effect of artificial ventilation combined continuous positive airway pressure(CPAP) with removal of tracheobronchial foreign bodies for children and to explore the possibility and security of the method. Methods 60 children with tracheobronchial foreign body, underwent total intravenous anesthesia ,were randomly divided into A group and B group. Each group had 30 cases. A group was given artificial ventilation with CPAP. The bronchofibroscope was connected to anesthesia machine with side hole after induction for 3 minutes,and high fresh gas flow(10 ～ 15L/min) was given to maintain continuous positive airway pressure. B group were given high frequency jet ventilation(HFJV) ,60 ～ 100 bpm. The mask ventilation was given in stand of bronchofibroscope when SpO2 ＜ 90% and until SpO2 improved. MAP, HR, ECG, SpO2, PaO2, PaCO2 were monitored and recorded at time points: T0 (entered operation room), T1 (beginning of bronchofibroscopy), T2 (5 min after bronchofibroscopy), T3 (10 min after bronchofibroscopy), T4 (end of operation). The side effects, the rate of fail to bronchofibroscopy and the rate of intubations after operation in two groups were observed and recorded. Results The HR of post-anesthesia in two groups significantly decreased than those at T0 (P ＜ 0.01), but no difference showed in HR between two groups(P ＞ 0.05). SpO2 and PaO2 of post-anesthesia in two groups significantly increased than those at T0 (P ＜0. 01) ,PaO2 at T1 ,T2 ,T3 in A group were significantly higher than those in B group(P ＜0.05). PaCO2 gradually increased after bronchofibroscopy in two groups ,and the values in A group was significantly lower than in B group(P ＜0.05 or 0. 01). There were no significant differences in the rates of fail to bronchofibroscopy and of intubations after operation between two groups, but the total number of B group was higher. Conclusion Artificial ventilation with CPAP for children with removal of tracheobronchial foreign bodies was safe and practical, and has a better controllability, a minor effect to respiratory function, deserve popularizing.

Glioma is the most common intracranial malignant tumor,with high incidence and recurrence rate,high fatality rate and the characteristics of low cure rate.Current treatment is given priority to with surgical treatment,auxiliary comprehensive therapy such as radiotherapy and chemotherapy.Hydrogen peroxide (H2O2) is a intermediate product of the cell oxygen metabolism which is a universal phenomenon in aerobic organisms.H2O2 is indispensable at various stages of tumor cell proliferation,infiltration and metastasis.Studies of the production of H2O2 and its function,the mechanism of apoptosis and the relationship between H2O2 and glioma cells can provide corresponding guidances for looking for a target gene for the treatment of gliomas.

Objective To observe the protective effect of asiatic acid on hyperlipidemia golden hamsters induced by high fat diet and explore its mechanism.Methods Hyperlipidemic golden hamsters fed with high-fat diet were administered orally with asiatic acid (8,16,32 mg/kg)for 4 weeks.Levels of serum lipid content,liver histology,hepatic GSH-PX and SOD levels,serum ALT and AST activities were evaluated in golden hamsters,fluorescence quantitative polymerase chain reaction(RT-PCR)is using to examine the liver lecithin cholesterol fatty acyl transferase(LCAT) and class B typeⅠscavenger receptor(SR-BⅠ)mRNA expression. Results Compared with model group,the levels of TC,TG,LDL-C,TC/HDL,ALT and AST in low and mediate asiatic acid groups were all significantly decreased but the levels of SOD and GSH-PX were significantly increased(P<0.01).HE staining results showed that fat deposition in the liver were improved by administration of asiatic acid,and the expression of LCAT and SR-BⅠmRNA were increased.Conclusion Asiatic acid can effectively reduce blood lipid levels,and alleviate liver damage of the hyperlipidemia golden hamsters by lipid regulation and antioxidative ability augmentation.The increased levels of LCAT and SR-BⅠmRNA expression maybe involved in the mechanism of hypolipidaemic effect of asiatic acid.

The changes of immunoreactive neurotensin (ir-NT) contents in the brain areas, pituitary gland and plasma in the trautized rats were observed by radioimmunoassay. The results showed the significant changes of the ir-NT contents in the hypothalamus, pituitary gland, plasma, injured tissue, hippocampus, central gray and spinal cord in the posttraumatic rats at different intervals. A predominant characterization of the change of ir-NT levels in the brain areas, pituitary gland and plasma, was the dramatical decrease at various times except for the hypothalamus, central gray, and hippocampus with biphasic alterations. The ir-NT contents in the frontal cortex, pons and medulla also displayed changes to different extent under the acute craniocerebral trauma condition These results suggest that NT may play a role in the pathophysiology of traumatic injury.
