Methods The detailed data of all cases from three hospitals at different levels of the injury surveillance during Jan 1st to Dec 31st 2006 in County Mei of Shanxi Province were collected.All the cases met the criteria of National Injury Surveillance Program. Results 2 469 cases were collected from the three hospitals.It was showed that men(68.29%) were more often injured than women(31.71%).Most sufferers were 25~44 years old,which accounted for 39.25%.The leading causes for injuries were traffic injury by motor vehicles(29.16%),falls(24.79%) and blunt injury(15.43%).Most injuries were slight,which accounted for 58.08%. Conclusion The top three causes of injuries in County Mei of Shanxi Province were traffic injury by motor vehicles,falls and blunt injury in 2006.Young males are the high-risk population prone to injuries.We should take counter measures to prevent and control injuries based on surveillance data analysis.

With decision tree model, both net utility and cost-benefit were analysed to comprehensively assess hepatitis B vaccination strategy in China. The result showed that neonates shoulUbe taken as the most favourable vaccinated population, infants aged 0～3 years the next, and immediate vaccination scheme was recommended. Although vaccination would result in negative benefit in the population aged 7 and over, certain net utility was also gained, Therefore we suggest that the subjects to be vaccinated be extended in due course.

AIM To investigate the effect of Supplemented Buyang Huanwu Decoction (Astragali Radix,Angelica tail,Paeoniae Radix rubra,etc.) on blood glucose in diabetic rats and its antioxidant activity.METHODS The diabetic rat model induced by streptozotocin (STZ) was established,with metformin as positive control group.After intragastric administration with Supplemented Buyang Huanwu Decoction,the fasting blood glucose,superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in serum and tissues (heart,kidney and pancreas) in rats were detected.HPLC was used to determine the contents of antioxidant constituents (calycosin-7-O-β-D-glucoside and peoniflorin) in plasma,whose pharmacokinetic parameters were then calculated.RESULTS Compared with the model group,the hypoglycemic activity in the Supplemented Buyang Huanwu Decoction group was obvious (P ＜ 0.05),the SOD activity in serum and various issues (except for pancreas) was significantly enhanced,together with significantly reduced MDA level (P ＜ 0.05).The pharmacokinetic behavior of two constituents (calycosin-7-O-3-D-glucoside and peoniflorin) accorded with two-compartment open model,whose blood concentrations reached the highest within 50-70 min,and showed no obvious changes within 180-720 min.CONCLUSION Supplemented Buyang Huanwu Decoction can reduce the blood glucose in diabetic rats and improve the antioxidant activities in heart and kidney.The fast absorption and slow metabolism of calycosin-7-O-3-D-glucoside and peoniflorin in decoction are beneficial to related treatment.

ObjectiveTo assess the efficacy and the immunological memory of plasma-derived hepatitis B vac- cine 11 years after the initial inoculation. Methods A randomized, double-blind and placebo-controlled trial design was used. Results The immunogenicity and protection rate of the vaccine were good 1 1 years after vaccination, how- ever, from 9 to 11 years after vaccination, the perscn year HBV infection rate showed no noticeable difference be- tween the vaccine group and placebo-controls. Furthermore, the immunological memory remained 11 years after in- oculation, but was significantly lower than that observed in the past 10 years. Conclusion Vaccine protection wanes over the years. More information is needed to define the appropriate time for vaccine booster doses.

Objective In order to observe the efficacy of low-dose in the third injection of hepatitis B vaccine. Methods 126 children aged 5～9 years were enrolled in a double-blind, place-controlled and randomized field trial. They were randomly divided into 10μg and 20μg dose group, and were redivided into 2μg, 5μg, 10μg, 20μg or non-in jected subgroups when the third booster injections were given. Results During the 9 years follow-up, the differences of the anti-HBs levels(GMT) among the groups were not significant at every time (P ＞ 0. 05). The GMTs at the ninth year(T108) were 7. 0, 6. 4, 9.9, 6.1, 9.7, 5. 4 and 7.4, respectively (P＞ 0. 05). The HBV infection rates among the groups had no significant difference (P ＞ 0. 05). The protective rates in the groups were all higher than 75％ at T108. Conclusion According to the data, it can be concluded that the third injection with low-dose has no influence on the vaccine efficacy(either short-term or long-term efficacy).

Objective To investigate the diagnostic value of MR fast scanning techniques in fetal congenital diaphragmatic hernia. Methods 12 cases diagnosed or suspected fetal congenital diaphragmatic hernia by ultrasound with gestational age (>20 weeks) were underwent MR examination.The fast scan sequences were as follows:Half-Fourier acquisition single-shot fast spinecho se-quence(HASTE)、True fast imaging steady-state precession sequence (True FISP)、Turbo FLASH T1 WI sequence.The axial,co-ronal and sagittal scanning were focused on fetal head and body.The results of prenatal MR examination was compared with neonatal surgical findings or autopsy results after inducing labor.Results All of 12 cases,9 cases were left diaphragmatic hernia,2 cases were right diaphragmatic hernia and 1 case was hiatal hernia.2 cases of them were complicated with other congenital malformations. The features of MRI were as follows:Some portions of bowels and stomach crossed into the thorax were visible in the HASTE and TRUE FISP sequence.The herniated stomach and bowels showed high or scattered high signals.The intestinal types were visible as well.The lung tissue intruded at the apex of the lung and the heart deviated to the opposite side were demonstrated.T1 weighted im-ages obtained from ultra-fast FLASH (Turbo FLASH)T1WI sequence showed characteristic high signals in the meconium,which delineated clearly the shape of the colon and small intestine.The prenatal MRI results of all cases were consistent with surgical (10 cases)and autopsy (2 cases)findings.Conclusion MR fast scanning techniques can clearly show fetal congenital diaphragmatic her-nia.Multiple sequences scanning can comprehensively map the organizational structure and anatomical relationship of fetal congenital diaphragmatic hernia with the surrounding tissues.MR fast scanning techniques play an important role in the diagnosis of fetal con-genital diaphragmatic hernia.

Objective To investigate the significance of galactose galectin-3(Galectin-3)and matrix metalloproteinase-2(MMP-2)expression in gliomas patients and thire role in process of gliomas' malignancy development. Methods Immunohistochemistry was used to detect Galectin-3 and MMP-2 protein expression in 5 normal brain tissue and 40 patients with different grade gliomas. According to positive cells number of Galectin-3,MMP-2 in tumor cells under a microscope,to determine the expression,and the positive index(LI)which came from the percentage of the positive cell number out of the total cell number was to expressed the number of positive cell. Results Galectin-3 and MMP-2 protein expression in normal brain tissue were negative. In glioma tissues,Galectin-3 was mainly expressed in the cytoplasm and membrane of tumor cells. In 23 glioma tissue withⅠor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 65 ± 3. 47)% in terms of Galectin-3 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of Galectin-3 expression was 76. 47%(13 / 17), and LI value was(27. 88 ± 22. 13)% . The difference of Galectin-3 expression and LI value were significant between specimens with Ⅰ,Ⅱ grade and Ⅲ,Ⅳ significant( χ2 = 4. 101,t = 4. 105;P < 0. 05). In human gliomas,MMP-2 expression protein was mainly expressed in tumor cells and vascular basement membrane of the endothelial cell cytoplasm. In 23 glioma tissue with Ⅰor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 91 ± 4. 78)% in terms of MMP-2 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of MMP-2 expression was 88. 24%(15 / 17),and LI value was(30. 06 ± 22. 94)% . The difference of MMP-2 expression was significant between specimens with Ⅰ,Ⅱ grade or Ⅲ,Ⅳ grade( χ2 = 7. 882,t = 4. 271;P< 0. 05). The linear correlation analysis showed that there was positively correlation between Galectin-3 and MMP-2 positive cells(r = 0. 800,P < 0. 05). Conclusion Galectin-3 and MMP-2 protein expression in Ⅰ,Ⅱgrade gliomas is significantly lower than those inⅢ,Ⅳ grade glioma,and they are positively related with the progress of malignant gliomas. Galectin-3 and MMP-2 protein can be used to evaluate or judge the malignant stage of human brain glioma.

Objective To evaluate DTI for early diagnosis and prognosis of diffuse axonal injury (DAI)in the moderate and sever traumatic brain injury (sTBI).Methods 30 patients with sTBI and 30 healthy controls were studied with T1 WI and DTI.The frac-tional anisotropy(FA)and ADC were quantified from different regions of interest(ROI)including the genu of corpus callosum(gCC), the trunk of CC,the splenium of CC(sCC)and the integrity CC.The FA and ADC of the same R0I was compared between TBI group and control group,and FA and ADC of the different parts of CC were compared in TBI group.Correlations between the FA or ADC and coma duration of the TBI patients were analyzed by Pearson linear correlation.Results Compared with control group,the FA value decreased significantly in each ROI,while ADC was reversed.The FA or ADC of the different ROI were correlated with co-ma duration in TBI group.Conclusion DTI is sensitive to detect the white matter injury of TBI.FA value detected in the CC can help diagnose DAI earlier and evaluate the degree of injury.
