Objective To reveal the hepatitis A vaccine (HepA) coverage among pre-school children in Shandong province before Hepatitis A vaccine was introduced to the EPI and to provide evidence for improving the strategy for hepatitis A control.Methods A cross-section survey was conducted among children aged between 2 and 6 years old in Shandong province in March 2008.The study population was selected by random sampling method and HepA immunization history was obtained by immunization record or recall.Results 78.90% had received one dose of HepA at least.The coverage rate decreased with age and the differences in three age groups were statistically significant (x 2 =11.54,P=0.02).The coverage rates among the boys and girls were 77.67% and 80.30% respectively,the difference was not significantly(x 2 =1.17,P=0.28).The HepA coverage rates among the children living in the eastern areas and in the richer areas were higher than the centrale and western areas and poverty areas,the difference has statistic significance (x 2 =27.25,58.17,P

AIM:We conducted an evaluation of clinical data with meta analysis to investigate the preventive effect of 5-aminosalicylic acid (5-ASA) on inflammatory bowel disease ( IBD)-associated colorectal cancer ( CRC) or dys-plasia (Dys) (IBD-CRC/Dys).METHODS: The information was retrieved from the main databases such as PubMed, Web of Science, the Cochrane Library, etc.All full-text articles about the prevention of IBD-CRC/Dys by 5-ASA were in-cluded if they conformed to the standards.The odds ratio ( OR) and its 95% confidence interval ( CI) were calculated. According to the types of IBD and the treatment course, the subgroup analysis was conducted, respectively.RESULTS:Fifteen articles were selected, including 5 038 IBD patients.Pooled analysis showed a protective association between 5-ASA and IBD-CRC/Dys (OR=0.53, 95%CI:0.37~0.76).Among them, both ulcerative colitis patients (OR=0.45, 95%CI:0.27~0.77) and Crohn disease patients ( OR=0.39, 95% CI:0.16~0.97) with 5-ASA therapy were less likely to develop CRC/Dys compared with those without 5-ASA treatment.5-ASA treatment for 1~20 years shows a pre-ventive benefit (OR=0.43, 95%CI:0.25~0.74).However, a minimum 5-ASA exposure of 2~6 months did not show a preventive benefit (OR=0.59, 95%CI:0.26~1.34).CONCLUSION:5-ASA protects against CRC/Dys in IBD pa-tients.Additionally, the protective effect is treatment time dependent.Treatment course for 1~20 years shows an evident preventive benefit.

Intertrochanteric fracture,a common kind of injury in orthopaedic surgery,often requires surgical intervention,especially the unstable ones.Since far back in 1995,Baumgaertner et al.recommended using the distance between the screw tip and femoral head apex (tip-apex distance,TAD) as a predictor of the risk of lag screw cutout,the importance of TAD has been recognized by orthopaedic surgeons.This concept has been widely accepted in practice,and even used as a standard in determining the helical blade position.It is not clear,however,whether the helical blade system is equal to lag screws in terms of TAD.After the limitations of TAD had been reported,Kuzyk et al.proposed a tip-apex distance referenced from the calcar (Cal-TAD) as a predictor of lag screw cutout to improve the concept further.In this article,these concepts and the latest clinical applications of TAD and Cal-TAD are reviewed based on the publications available.

Objective To observe the expressions of CD26, Ki67 and epidermal growth factor receptor(EGFR) proteins in thyroid neoplasms, to explore their value in differential diagnosis between benign and malignant thyroid neoplasms and to search for molecular marker in well-differentiated thyroid carcinomas.Methods The expressions of CD26,Ki67and EGFR proteins were examined by immunohistochemistry in 50 differentiated thyroid carcinomas (TC) and 50 thyroid adenomas (TA) and their relationships were analyzed.Results The positive rate and expression intensity of CD26,Ki67and EGFR proteins in TC were significantly higher than those in TA, and especially higher in follicular TC than those in follicular TA.Conclusion The abnormal expressions of CD26, Ki67and EGFR proteins appear to be valuable in differential diagnosis and predicting prognosis of thyroid carcinomas, especially CD26 can be used as a diagnostic marker in well-differentiated carcinoma of follicular cell origin.

BACKGROUND:Posterior arch length deficiency is closely related to the formation and development of malocclusion.
OBJECTIVE:To measure the posterior arch length in individual normal occlusions of adults in Lanzhou.
METHODS:A total of 102 current col ege students with individual normal occlusions, with a mean age of (19.33±2.67) years (range 18-24 years), including 47 males and 55 females from Gansu Province, were chosen to take lateral cephalograms. Al research objects were divided into three groups according to mandibular plane angle:high angle group (Frankfort mandibular-plane angle>32°), low angle group (Frankfort mandibular-plane angle<22°) and control group (22°≤Frankfort mandibular-plane angle≤ 32°). Posterior arch length of both maxil ary and mandibular arches was measured, and the data were compared between genders and groups and in groups.
RESULTS AND CONCLUSION:Posterior arch length of maxil ary arch was slightly longer in male group than that in female group, and the difference was not significant (P>0.05). The posterior arch length of mandibular arch was slightly longer in male group than that in female group, but the difference was no significant (P>0.05). Comparison between groups revealed that the posterior arch length of low angle mandibular arch was significantly longer than that of high angle mandibular arch in male group, and the difference was significant (P<0.05). The results indicate that the gender wil not influence the development of posterior arch length. Different vertical facial types and different genders have different posterior arch length in individual normal occlusions of adults
