Objective To investigate the correlation of Helicobacter pylori (HP) infection and serum carbohydrate antigen 724 (CA724) level .Methods 229 patients with HP infection hospitalized in gastroenterology department were enrolled in the observa‐tion group ,and patients were divided into different disease group according to the results of diagnosis .Other 100 healthy people , conducted physical examination ,were enrolled in the healthy control group .The HP infection was detected by 13C‐urea breath test and the serum CA724 level was detected by chemiluminescent immunoassay .Results The HP value and serum CA724 levels in each disease group were higher than those in the healthy control group ,with significant differences(P<0 .05) .The HP value was highest in the duodenal group ,and there was no statistical differences between each disease groups (P>0 .05) ,except the duodenal group .The serum CA724 level was highest in the gastric cancer group ,there was no statistical differences between each disease groups(P>0 .05) ,except the gastric cancer group .The serum CA724 level was positively correlated with HP value in patients with HP infection(r=0 .331 ,P<0 .01) .Conclusion HP infection may correlate with serum CA724 level .The serum CA724 level in the gastric cancer group increased more significantly ,in other disease groups increased steadily .Dynamic observation of serum CA724 level in patients with upper gastrointestinal tract disease associated with HP infection could be helpful for early diagnosis and pre‐vention of aggravation of lesions ,and could provide effective diagnosis basis for early detection of upper gastrointestinal tract le‐sions ,such as gastric cancer .

Objective To compare the effects of low-molecular-weight heparin (LMWH,fragmin) and aspirin versus aspirin alone on transient myocardial ischemia and in-hospital prognosis in patients with unstable angina pectoris (UAP).Methods A total of 86 patients with UAP were randomized into a group receiving aspirin (ASP group) a group receiving aspirin plus LMWH (fragmin group) for one week.Results The effective rate was 88.37% in the fragmin group and 67.44% in the aspirin group after one week (P

Objective To investigate the possible mechanisms of teratogenesis caused by passive smoking, temporospatial changes in surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it were explored. Methods The pregnant golden hamsters were randomly divided into the treated group and the control groups. In the chamber made by ourself for passive smoking experiment, the animals of the treated group were exposed to smoke from embryonic day 4 to 7, 3 times per day for 4 consecutive days. At twelve o'clock and eighteen o'clock of embryonic day 8, eight o'clock of embryonic day 9 and eight o'clock of embryonic day 10 respectively, the pregnant golden hamsters of both treated group and control group were sacrificed, the uteri were removed and embedded routinely with paraffin, sectioned transversely in series. The sections of each group were stained with immunohistochemical ABC method and concannavalin agglutinin (ConA) and ulex europaeus agglutinin (UEA) were used as molecule probes to conduct the qualitative and quantitative analysis of the fibronectin and the related surface carbohydrates of the embryonic neural epithelium and the mesenchyme around it. Results During embryonic day 8 to10 of golden hamsters fibronectin reduced(F=30.168,P

Objective To explore the expression and clinical significance of EphA2 and E-eadherin in colorectal carcinoma.Methods The expression of EphA2 and E-eadherin in 67 cases of eoloreetal carcinoma and 28 cases of normal large intestine tissues were determined by immunohistochemieal method(S-P method),and their relationship to elinicopathological characteristics were analyzed.Results The positive expression of EphA2 and negative expression of E-cadherin in colorectul carcinoma tissues were significantly higher than those in normal intestine tissues(P<0.01).F111e positive expression of EphA2 and negative expression of E-eadherin were positively correlated with tumor histological grade,invasive depth and lymph node metastasis(P<0.01 orP<0.05),but not correlated with tumor～ross type(P> O.05).The expression of EphA2 was negatively related with E-cadherin.Conclusions The abnormal expression of EphA2 and E-cadherin may be together involved in the development and progression of eolorectal carcinoma,It may be a good marker for monitoring the malignant degree and the prognosis of colorectal carcinoma by combining E-eadherin and EphA2.

Objective To explore the correlation between executive function and white matter lesions (WML) and the diagnostic value by clock drawing test(CDT) in patients with vascular dementia (VaD). Methods Twenty-seven VaD patients and twenty-five normal control subjects were evaluated with CDT to assess the executive function. CDT was scored according the four point method. Age-related white matter change rating scale (ARWMCrs) was used qualitatively to measure and locate the WML by cranial MRI scanning. Results 1. The scores of CDT in normal cognition health and VaD were ( 3.88 ± 0. 33 ) and ( 1.74 ± 0. 98 ). The difference between two groups was statistically significant (P＜0. 01 ). The humerous part and the point part were the earliest to decline in the VaD Patients. The scores of WML were (5.12 ± 4. 19) and ( 11.19± 3.09), respectively. There was significant difference between two groups(P ＜ 0. 01 ). The scores of CDT had significant positive correlation with MMSE scores and negative correlation with WML scores (P ＜ 0. 01 ). Conclusion The executive functional impairment in patients with VaD could be associated with the degree of WML.

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

Objective To investigate the characteristics and extent of mononuclear ceils DNA damage in peripheral blood of mice fed with low dose T-2 toxin and Deoxynivalenol(DON) alone or in combination and to explore the long-term toxicity of the toxin at sub-clinical dose. Methods Eighty female Balb/c mice weighing (14.0 ± 1.5)g 3 weeks after birth were divided randomly into control group, T-2 toxin group, DON group and T-2 toxin combined with DON group according to their body weight, 20 in each group. The mice were injected intraperitoneally T-2 toxin(5 μg·kg-1·d-1), DON(20 μg·kg-1·d-1), T-2 toxin(5 μg·kg-1·d-1) combined with:DON (20μg·kg-1·d-1)respectively,control group were treated by isotonic NaCl. In 16 weeks and 21 weeks of exposure, the tail blood of the mice was collected. The comet rate, tail DNA content,tail length and tail extent moment of mouse mononuclear ceils in peripheral blood was observed using single cell gel electrophoresis(SCGE). Results ① In T-2 toxin group,tail DNA content,tail length and tail extent moment were (27.71 ± 15.85)%, (13.67 ± 5.56)μm, 4.26 ± 3.83 at 16 weeks and (28.38 ± 15.57)%, (13.83 ± 5.47)μm, 4.37 ± 3.82 at 21 weeks, all levels of the indexes increased. In the control group, the corresponding values were (11.87 ± 4.61)%, (10.59±6.70)μm, 1.34±0.98 at 16 weeks and (11.31 ± 3.94)%, (10.83 ± 7.05)μm, 1.29±1.01 at 21 weeks, the differences in the two groups were significant (all P < 0.05) ;②In DON group, the comet rate of cells, tail DNA content and tail extent moment of comet ceils were 5.62%, (28.13 ±13.31)%, 3.39 ± 2.35 at 16 weeks and 7.71%, (29.17 ± 15.12)%, 5.70 ± 4.17 at 21 weeks. In the control group, the tailing rate was 4.34% at 16 weeks and 4.38% at 21 weeks, the differences in the two groups were significant (all P < 0.05);③In the group of T-2 toxin combined with DON,the comet rate, tail DNA content, tail length and tail extent moment was 6.21%, (30.14 ± 15.48)%, (16.93± 6.58)μm, 5.54 ± 4.22 at 16 weeks and 8.17%, (30.85 ± 15.76)%, (17,21±6.45)μm, 5.70 ± 4.17 at 21 weeks. Moreover, the levels were significantly higher than that in the control group(all P < 0.05). The tail DNA content and length of comet cell tail significantly increased in the combine group compared with T-2 group or DON group(P < 0.05). Conclusions Low dose T-2 toxin or DON can definitely result in DNA damage of mononuclear cells in peripheral blood of mice. The damage induced by T-2 toxin combined with DON is severer than that caused by T-2 toxin or DON alone.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.
