A total of 1 277 ESTs of Angiostrongylus cantonensis were downloaded from GenBank and analyzed with BlastX.SignalP V3.0 analysis was applied to predict potential putative antigen or allergen relative proteins with N-terminal secreted signal peptides or signal anchors.BlastX analysis showed that there were 614 ESTs scored more than 100, of which 14 were identical with A.cantonensis, 60 ESTs did not match any proteins in the databases.The identified 614 ESTs could be grouped into 10 categories, 80 ESTs expressed 22 antigen or allergen relative proteins, in which 12 had N-terminal secreted signal peptides and 3 had signal anchors.

Objective To find out the difference in expression of glial fibrillary acidic protein and neuron-specific enolase in hippocampi and olfactory bulb of Alzheimer's disease rats,and the relationship between olfactory and Alzheimer's disease.Methods Adult rats,the expression of GFAP and NSE in hippocampi and olfactory bulb was measured by immuhistochemical after a single intracerebroventricular injection of ?-amyloid peptide,and change of these protein in olfactory.Results Comparing the hippocampi and olfactory of model and control,the expression of GFAP in model group increased evidently,the expression of NSE descended animals.Conclusion There is significant difference in olfactory system between Alzheimer's disease model and control group rats.

Objective To investigate the expression and the effect of nuclear factor-?B(NF-?B) in neonatal sepsis.Methods We separated 77 newborn infants into 3 groups, which were septic group (26 cases),non-septic group (31 cases) and control group (20 cases). NF-?B existed in PBMC was detected in 3 different periods, including at admission, after the 24th hour and 48th hour of admission, of the septic group and the non-septic group by flow cytometry. At the same time, the sample of the septic group and the non-septic group were drawn for blood cultures at admission before using antibiotics.Results The expression of NF-?B in septic group was more significant than that in the other 2 groups (P

Objective To investigate the changes of vitamin D level and its relationship with bone alkaline phosphatase(BAP)and parathyroid hormone(PTH)in infants fed with breast milk and vitamin D supplementation for 0-8 months in People`s Hospital of Longhua New District in Shenzhen city.MethodsTotally 67 newborns in the Department of Obstetrics and Gynecology of People`s Hospital of Longhua New District were selected.These newborns were breastfed and began to supplement vitamin D 400 U/d in the 15th day after birth.The serum 25-(OH)D3 and BAP and PTH levels were measured in newborns and 4-/8-month-old infants,and the correlations of serum 25-(OH)D3 with BAP and PTH were analyzed by Pearson correlation analysis.ResultsCompared with the newborns,the serum 25-(OH)D3 [(78.47±36.41)nmol/L,(75.26±34.73)nmol/L],BAP[(231.43±78.81)μg/L,(205.97±71.64)μg/L],PTH[(31.76±11.54)pg/ml,and(32.94±13.82)pg/ml] levels of 4-and 8-month-old infants were significantly higher,and the difference were statistically significant(t4 months=7.823,12.568,11.852,t8 months=7.364,9.473,11.947;all P=0.000).There was a negative correlation between serum 25-(OH)D3 and BAP in newborns and 4-/8-monthold infants(r=-0.372,-0.463,-0.309;P=0.008,0.016,0.021),the serum BAP was positively correlated with PTH in infants aged 4 months and 8 months(r=0.487,0.338;P=0.005,0.032),and the serum 25-(OH)D3 was negatively correlated with PTH in infants aged 4 months(r=-0.297,P=0.041).Conclusions Infants at birth are prone to vitamin D deficiency in Shenzhen City.After 4 months of breastfeeding and vitamin D400U/d supplementation,the vitamin D levels in most infants become normal.25-(OH)D3 is correlated with BAP and PTH in different months.

Objective To compare the changes of blood coagulation system and the clinical interventional effect of low molecular weight heparin (LMWH) in elderly patients who had received thoracic surgery. Methods Ninety-six thoracic surgery patients (age≥70 years) were divided into control group ( 54 cases ) and experimental group ( 42 cases ) ( postoperative 1-7 days, subcutaneous injection with LMWH ) from September 2007 to December 2009 by random digits table. Observed perioperative changes in prothrombin time (PT),activated partial thromboplastin time (APTT),platelet (Plt),D-dimer (D-D),fibrinogen (Fib), anti- X a activity, and clinical performances. Also observed the influence of diabetes mellitus of surgery coagulation function. Results The preoperative indexes of coagulation function were no significant (P ＞ 0.05 ). In control group PT prolonged, Fib and D-D increased, the differences between preoperative and postoperative each time were significant (P ＜ 0.05 ). Fib and D-D in control group increased than those in experimental group postoperative each time (P ＜ 0.05 ). In experimental group anti- X a activity increased postoperative each time (P ＜ 0.05 ),compared with control group was also significant (P ＜ 0.05 ). Diabetes mellitus had no significant influence on coagulation function. One patient appeared pulmonary thromboembolism in control group,and no one appeared venous thromboembelism and bleeding adverse reactions in experimental group. Conclusion Thoracic surgery in elderly patients have high blood coagulation state, prone to venous thromboembolism, LMWH given early postoperative prophylactic treatment is beneficial to improve the hypercoagulable state and have better security.
