Objective To study the diagnostic value of anti-neutrophil cytoplasmic antibody (ANCA) detction in patients with systemic lupus erythematosus (SLE). Methods Indirect immunofluorescence (IIF) and Western blotting were applied to detecting the expression of sera ANCA, antinuclear antibody (ANA), anti-double-stranded DNA antibody, anti-SmithD1 antibody in 25 samples of control group and 106 samples of patients with SLE. Results ALL samples of control group showed negative; 47.2% (50/106) sera showed ANCA positive in patients with SLE,and all of them were peripheral nuclear pattern (pANCA). In ANCA positive group, the positive rate of ANA, anti-SmithD1 antibody and anti-ds-DNA antibody was respectively 100% (50/50), 82% (41/50) and 94% (47/50); in ANCA negative group, the positive rate was respectively 91.1% (51/56), 67.9% (38/56)and 50% (28/56). There were no statistical differences in positive rates of ANA and anti-SmithD1 antibody between ANCA positive and negative groups (both P＞0. 05), but there was in positive rates of anti-ds-DNA antibody (P＜0.01). ANCA positive rate was respectively 84.6% (44/52) and 11.1%(6/54) in active SLE group (n=52) and inactive SLE group (n=54) (P＜0.01). Conclusion The determined ANCA in patients with SLE is not correlative with ANA and anti-SmithD1 antibody, but positively relates to anti-double-stranded DNA antibody. The positive rate of ANCA in patients with active lupus is significantly higher than that in non-active lupus.

Objective To investigate the effect of metabolic parameters on the self-efficacy in patients with diabetes mellitus.Methods 175 diabetes mellitus patients were recruited by random sampling method.Demographic data and metabolic parameters were obtained and the scales of self-efficacy of diabetes patients were evaluated by secd6.We further analyzed the effect of metabolic parameters on the selfeffficacy in diabetes mellitus patients.Results Two-hour postprandial blood glucose had negative correlation with self-efficacy among 10 metabolic parameters in diabetes mellitus patients.Conclusions Twohour post-prandial hyperglycemia affects the scale of self-effcacy.So we should strengthen the management of two-hour postprandial hyperglycemia to increase the self-efficacy in diabetes mellitus patients.

Objective To study whether intranasally administered transforming growth factor beta1(TGF-?1)can reach central nervous system(CNS)through the trigeminal nerve pathway.Methods Nineteen healthy male SD rats were randomly assigned into control group(n=6)and administration(IN)0.5h group(n=3),1h group(n=4),2h group(n=3)and 6h group(n=3).Rats in IN groups were given 50?l(20?g)recombinant human TGF-?1(rhTGF-?1)intranasally and were sacrificed at 0.5,1,2 or 6h after IN following blood sample collection.The cerebellum,midbrain,pon,medulla and trigeminal nerve were separated quickly and the concentration of TGF-?1 was analyzed by ELISA.Results Compared with the control group(15.01?1.50pg/mg),TGF-?1 was significantly elevated in the trigeminal nerve in all the IN groups(P0.05).TGF-?1 concentrations in plasma and other caudal CNS regions,such as cerebellum,midbrain and cervical spinal cord,were not significantly changed compared with that in control group.Conclusion TGF-?1 is likely to be absorbed by the trigeminal nerve following intranasal administration,and is subsequently delivered to some brain regions through the trigeminal nerve pathway,which may provide a potential treatment strategy for trigeminal nerve and CNS disorders.

Approximately one-quarter of ischemic stroke occurred in vertebrobasilar artery system. Atherosclerotic vertebrobasilar artery stenosis is one of the major causes of posterior circulation stroke. In addition to the conventional medical and surgical treatment, endovascular intervention has received more and more attention, and it has become the most promising therapeutic approach.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is characterized by repeated episodes of upper airway obstruction that results in brief periods of breathing cessation (apnea) or a marked reduction in airflow (hypopnea) during sleep. Asthma is a chronic inflammatory disease of the airways characterized by revesible air-flow obstruction and bronchial hyperresponsiveness. This article reviewed related reseaches progress of relationship between the obstructive sleep apnea hypopnea syndrom and asthma in the vascular endothelial growth factor, systemic inflammation, leptin, obesity, gastroesophageal reflux disease and upper airway diseases, excessive daytime sleepiness and asthma control.

The primary etiopathology of pediatric OSAHS includes tonsil or adenoid hypertrophy. Severe OSAHS contributes to or aggravates thoracic deformity, which is rarely reported. In the current report, This children sleep snoring more than 4 years, increasing with thoracic severe depression during sleep 2 days. Clinical examination indicated tonsil and adenoid hypertrophy, and polysomnography revealed OSAHS . The symptoms of OSAHS and severe inhalation-related sternum depression disappeared rapidly after tonsillectomy. Our findings indicated that OSAHS were the major causes underlying funnel chest in children. The rarity of the incidence may result in missed diagnosis or misdiagnosis. Polysomnography was recommended for the child diagnosed with funnel chest accompanied by upper airway stenosis.

Objective To investigate whether folate deficiency cause high expression level of interferon gamma (IFN-γ) resulted from IFN-γ gene ( IFNG) hypomethylation and then promote the pathogenesis and development of ulcerative colitis (UC ) in a dextran sulfate sodium (DSS )-induced experimental colitis model in mice .Methods A total of 24 female BALB/c mice were divided into four groups ,six mice in each group , including folate deficient/DSS+ group , standard diet/DSS+ group , standard diet/DSS - group and folate deficient/DSS- group .At the beginning of the sixth week since fed , the mice of model groups were treated with 5% DSS to establish experimental colitis .By the end of the sixth week ,disease activity index (DAI) of colitis and histological changes were evaluated .The folate level of peripheral blood serum of mice were detected by enzyme-linked immunosorbent assay (ELISA ) . The expression of IFN-γ in colonic mucosa of mice was examined by immunohistochemistry . The methylation level of CpG island in the promoter region of IFNG was determined by methylation specific polymerase chain reaction (MSP) .The t test was used for measurement data .Chi square test was performed for comparison between groups of count data . Spearman correlation analysis was used for correlation analysis .Results The folate levels of peripheral blood serum of folate deficiency/DSS+ group and folate deficiency/DSS- group ((2 .70 ± 0 .19) and (2 .80 ± 0 .25)μg/L) were significantly lower than those of standard diet/DSS+ group and standard diet/DSS- group ((13 .62 ± 0 .38 ) and (13 .52 ± 0 .77)μg/L ,t= -63 .33、32 .27 ,both P< 0 .05) ,resepectively .The expression of IFN-γ in colonic mucosa of folate deficiency/DSS+ group and standard diet/DSS+ group were significantly higher than those of folate deficiency/DSS- group and standard diet/DSS- group (χ2 = 22 .18 ,P< 0 .05 ) . And the expression of IFN-γ in colonic mucosa of folate deficiency/DSS+ group was also higher than that of standard diet/DSS+ group (χ2 = 12 .00 ,P< 0 .05) .The expression level of IFN-γ of folate deficiency/DSS+ group and standard diet/DSS+ group was positively correlated with (r=0 .998、0 .953 ,both P<0 .01) .The folate levels of peripheral blood serum of folate deficiency/DSS+ group was negatively correlated with IFN-γexpression level and DAI (r= -0 .880 and -0 .926 ,both P<0 .05) .No abnormal methylation was detected in IFNG promoter CpG island in colonic mucosa tissues of mice of each group . Conclusion In the mice model of DSS induced acute experimental colitis ,folate deficiency may increace the expression of inflammatory factor IFN-γand enhance the inflammation activity of colonic mucosa .

Objective To investigate the synergism and attenuation effects of Scapharca Subcrenata Extraction on NP chemotherapy in model mice.Methods The models of nude mice were induced with A549 cell line xenograft.The tumor inhibiting rates, body weight, food intake, hematology and blood biochemistry index were determined to evaluate the synergism and attenuation effects of Scapharca Subcrenata Extraction (125、250、500 mg/kg, i.g) on NP chemotherapy. Results Compared with NP chemotherapy group, the tumor inhibiting rates, body weight, food intake, white blood cell number were increased and glutamate pyruvate transaminase, glutamic oxalacetic transaminase and urea nitrogen were decreased markedly in NP chemotherapy plus Scapharca Subcrenata Extraction groups. Conclusion Scapharca Subcrenata Extraction has a remarkable synergism and attenuation effects on NP chemotherapy.
