Objective To investigate the effect of melatonin on serum malondialdehyde (MDA), NF-κB, tumor necrosis factor-α(TNF-α) andβ2-microglobulin (β2-MG) levels in secondary brain damage following intracerebral hemorrhage patients.Methods 90 patients secondary brain damage following intracerebral hemorrhage were divided into experimental group and control group, 45 cases in each group.The control group were given conventional treatment after surgical removal of hematoma, and the experimental group, on the basis of control group, were given melatonin capsule (6 mg melatonin) , orally, once a day, for 2 weeks treatment.The levels of MDA, NF-κB, TNF-αand β2-MG in patients’ serum were detected.Results The MDA, NF-κB, TNF-αand β2-MG levels after treatment significantly decreased compared with before treatment in two groups (all P<0.05), and the above indexes in experimental group significantly decreased compared with control group ( P <0.05 ).Conclusion Melatonin can significantly reduce the levels of MDA, NF-κB, TNF-αand β2-MG levels in brain injury patients with cerebral hemorrhage, and repair brain damage, which has a guiding significance for clinical use.

Objective:To investigate the inhibitiory effect of CD59-siRNA on CD59 gene expression and the growth of xenografted ovarian cancer in vivo,and to explore the role of CD59 in tumor immune escape.Methods:A2780 cells transfected with siRNA plasmid (T group),A2780 cells transfected with blank plasmid (V group) and the wild A2780 cells (C group) were subcutaneously injected into nude mice,respectively.The inhibitiory effect of CD59-siRNA on tumor growth and CD59 expression was evaluated by tumor growth curves and in situ hybridization (ISH) and immunohistochemistry (IHC).Results:The tumor growth curves demonstrated that the growth of cells transfected with siRNA plasmid was significantly inhibited (P<0.05).ISH and IHC showed that the expression of CD59 mRNA and CD59 protein were decreased significantly compared with other groups (P<0.05).Conclusion:Studies of in vivo experiment demonstrate that CD59-siRNA significantly inhibites the expression of CD59,increases the sensitivity of A2780 cells to the complement attack and inhibites the tumor growth.The results may further indicate the role of CD59 in tumor immune escape.

Objective To investigate the clinical application and significance of nasotracheal intubation (NTI)on patients with respiratory failure.Methods 72 cases of post-operative and non-operative patients with respiratory failure were performed with urgent NTI or blind nasotracheal intubation(BNTI)and then mechanical venfilation.Results In all of the cases NTI were successful.32 cases received direct vision NTI;26 cases were BNTI:9 case8 were NTI through fibrobronchoscope and 5 cases were NTI under awake surface anesthesia.Operation were performed within 20 second to 11 minutes[(5.1±3.1)min].The remaining time of tracheal catheter were 2～21d [(9.3±5.9)d].Conclusion NTI was an important measure in rescuing the patients with respiratory failures.It is an essential rescue technique under the condition without fibrobronchoseope.

Objective To investigate the association between intima-media thickness (IMT) and free fatty acids (FFA) in hypertensive patients with metabolic syndrome (MS). Methods IMT, FFA and body mass index (BMI) were measured in 69 hypertensive patients with metabolic syndrome (MS group) ,57 hypertensive patients without metabolic syndrome ( Non-MS group) ,and 50 healthy controls ( NC group). Results In the MS group,The BMI, serum levels of triglyceride (TG), fasting blood glucose (FPG) and FFA were ( 26.0 ± 2.1 ) kg/m2, (24.0 ±0.81 ) mmol/L and (5.64 ± 0.82) mmol/L respectively, which were significantly higher than those in the Non-MS group ( (24.9 ± 2.3 ) kg/m2, ( 1.93 ± 0. 55 ) mmol/L and ( 5.10 ± 1.08 ) mmol/L respectively ) and the NC group ( (23.6 ± 1.6), ( 1.49 ± 0.36) mmol/L and (4.70 ± 0.90) mmol/L respectively) ( F = 20.06, 30.96 and 15.17,P ＜0.05 or 0.01 ). FFA in the MS group ((562.11 ± 55.12)μmol/L) were significantly higher than that in the Non-MS group (402.65 ± 49.53 ) μmol/L) and the NC group ( ( 356.23 ± 45.93 ) μmol/L) ( F = 277.28, P ＜0. 01 ). IMT in the MS group, Non-MS group and NC group were (1. 10 ± 0. 13 )mm, (0. 82 ± 0. 12 )mm and (0.70 ± 0.11 ) mm, respectively, with significantly difference ( P ＜ 0. 01 ). In addition, the incidence of thickening was 28.99% (20/69), 17.54% ( 10/57 ) and 2.00% ( 1/50 ), respectively, with significantly difference ( P ＜0.01 ). Conclusions Serum level of FFA is associated with IMT in hypertensive patients with metabolic syndrome.

ObjectiveTo evaluate the status of ANCA(antineutrophil cytoplasmic antibodies) positivity in Uygur nationality and Han nationality patients with ulcerative colitis (UC); and the possibility of the ANCA as a genetic marker of susceptibility between Uygur and Han nationality patients with ulcerative colitis in the same area. MethodsSerum samples from 39 Uygur and 31 Han patients with UC, 30 Uygur and 30 Han patients with diarrhea of other causes, 30 Uygur and 30 Han subjects as healthy controls were examined for ANCA using indirect immunofluorescence. Results ANCA was detected in 24 of 39(61.5%) Uygur patients with UC, 11 of 30( 35.5%) Han patients with UC, 1 of 30(3.3%) Uygur patients with diarrhea of other causes, none of 30 Han patients nor in the two healthy controls. It showed that the positive rate in Uygur patients with UC was significantly higher than in Han patients with UC (P0.05). Conclusions ANCA is useful in distinguishing patients with UC from other diarrhea diseases. ANCA may be a potential marker of genetic susceptibility to UC.
