Objective To investigate the expression of Sonic hedgehog(SHH)and WNT/β-cate-nin in human pancreatic cancer and explore its clinical significance.Methods Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot assay were used to determine the mRNA and protein expression of SHH and β-catenin in human pancreatic cancer tissue and normal tissues adjacent to cancer.Results The SHH mRNA and protein expression was detected in 81.6% and 79.6% of pancreatic cancer, respectively.The β-catenin protein expression was 71.4% in pancreatic cancer tis-sues.These were significantly different from those of normal tissue adjacent to cancer (P<0.05).But the expression level of β-catenin mRNA was low in both pancreatic cancer tissues and normal tissues.There was no significant difference between them (P>0.05).The expression of SHH and β-catenin protein in pancreatic cancer had no correlation with age, tumor size, pathological type and tumor site (P>0.05), but had a relationship with lymph node metastasis and TNM stage (P<0.05).The cor-relation between SHH and β-catenin protein was positive (r=0.352, P<0.05).Conclusion The SHH and WNT/β-catenin signaling pathways were active in human pancreatic cancer.The crosstalk between these pathways may play an important role in the carcinogenesis and development of pancreat-ic carcinoma.

Objective:To analyze the secular trends of height among Chinese students aged 17 in dif-ferent ethnic minorities from 1985 to 2010. Methods:A total of 18 Chinese ethnic minorities’ students, including Mongolian, Hui, Uygur, Zhuang, Korean, Tibetan, Miao, Buyi, Dong, Bai, Tujia, Hani, Dai, Lisu, Wa, Nakhi, Tu and Qiang as subjects were sampled from the 1985, 1995, 2000, 2005 and 2010 Chinese National Surveys on Students’ Constitution and Health. The heights of 17 years old people by gender in various ethnic minorities were analyzed and compared. Results:From 1985 to 2010, the in-crements of adult heights increased significantly in many ethnic minorities’ boys. In 2010, the average height of boys aged 17 years in each minority group was higher than 162 cm and was higher than 170 cm among boys from Hui, Mongolian and Korean groups. The ethnics with height growth rates of more than 2 cm per decade in boys were Hui (2. 64 cm/decade) and Dong (2. 05 cm/decade) and the ethnics with height growth rates of more than 1 cm per decade were Korean (1. 99 cm/decade), Tibetan (1. 90 cm/decade), Hani (1. 80 cm/decade) and the other 9 minority groups. The average height of girls aged 17 years in each minority group was higher than 150 cm in 2010 . The heights showed an upward trend in 15 minority groups, but with different degrees. The ethnics with height growth rates of more than 1 cm per decade were Hui (1. 56 cm/decade) and Korean (1. 29 cm/decade). The increments that were signifi-cant between 1985 and 2010 were Hui (3. 89 cm), Korean (3. 23 cm), Dong (2. 35cm) and the other 6 minority groups ( P<0 . 05 ) . Conclusion: Our data suggest that the increments of adult heights may reflect the secular growth change in the major minority groups during the past 25 years, but there was an obvious disequilibrium among various ethnic minorities. We should pay more attention to the minority groups with poor growth and give them more help. Meanwhile, we should also pay attention to the nega-tive effects of the secular growth trend on those minority groups with fast increasing adult height.

Objective:To analyze the prevalence of anemia and its proportions of severity,and to exa-mine the association between anemia and nutritional status among Chinese students of ethnic minorities, so as to provide bases for the prevention and treatment of anemia.Methods:The subjects were Mongoli-an,Hui,Zhuang and Korean students aged 7,9,1 2,1 4 and 1 7 years,sampled from the 201 0 Chinese National Surveys on Students’Constitution and Health.World Health Organization (WHO)criteria for screening anemia (2001 )was used,and the proportion rates of mild,moderate and severe were ana-lyzed.The nutritional status was defined according to the growth references of body mass index (BMI)-for-age z-score for 5 -1 9 years developed by the WHO.Stepwise Logistic regression was used to assess the association between anemia and nutritional status,gender,urban /rural areas,age and ethnic minori-ties.Results:The prevalences of anemia were 4.4%,26.4%,6.6% and 5.8% in Mongolian,Hui, Zhuang and Korean students,respectively,of whom,the prevalence of anemia was highest in rural girls and reached 4.8%,42.0%,9.0% and 6.7%,respectively.Most of the ethnic minorities’students belonged to mild anemia,and the prevalence of severe anemia was 1 .4%,1 2.9%,1 .6% and 1 .9% in Mongolian,Hui,Zhuang and Korean students,respectively.Stepwise Logistic regression showed that the girls,rural students,students aged 1 2 years and 1 7 years,Hui,Zhuang and Korean students were more likely to develop anemia than the boys,urban students,students aged 7 years and Mongolian students. The overweight students were less likely to develop anemia compared with the normal students and there was no significant association between anemia and thinness or obesity when the other factors were con-trolled (P >0.05).Conclusion:The epidemic of anemia was different in the different ethnic minorities and the prevalence of anemia in Hui students was of moderate public health concern according to the WHO’s criteria.We should pay more attention to the prevention and treatment of anemia for Hui and eth-nic minorities in rural areas,especially for rural girls.The nutritional status of students could not be a ba-sis or judgement for anemia as there was no significant association between anemia and nutritional status.

Blood Replenishing Angelica Decoction [Danggui Buxue Tang (DGBXT)]is a wellknown TCM prescription composed of Radix Angelicae Sinensis and Radix Astragali with the actions ofinvigorating "Qi" and enriching blood. Its action to curtail endothelial permeability induced by histaminewas studied. Endothelial cells isolated from the aorta of neonatal calf were cultured on polycarbonate mi-croporus filter membrane to develop a confluent endothelial monolayer. After purfused with either plainHank's balanced salt solution or that containing 5 g/L albumin, the monolayer was treated with 10-4 mol/L histamine for 30 min either with or without preincubation for 60 min with 10-4 g/mL of DGBXT. Fluidfiltration coefficient (Kf), filtration volume (Jv) and osmotic reflective coefficient (σ) of protein were thenmeasured. The findings showed that DGBXT could curtail the lowering of Kf and Jv and elevation of σ in-duced by histamine, indicating that DGBXT could inhibit the action of histamine on endothelial permeabili-ty, but its mechanism of action needs further study.

Objective Based on the diagnostic technique of electric meridian detection, to observe the clinical efficacy of acupuncture in treating angioneurotic headache.Method Totally 106 patients with angioneurotic headache were randomized into a treatment group and a control group, 53 cases in each group. The treatment group received acupuncture based on the electric meridian detection, while the control group received medication treatment. The hemorheology indexes [plasma viscosity (PV), erythrocyte sedimentation rate (ESR)] and McGill Pain Questionnaire (MPQ) [Pain Rating Index (PRI), Visual Analogue Scale (VAS), and Present Pain Intensity (PPI)] were observed before and after intervention, and the clinical efficacies were compared. Result The total effective rate was 88.7% in the treatment group versus 71.7% in the control group, and the between-group difference was statistically significant (P<0.05). After intervention, the hemorheology indexes and MPQ scores were significantly changed in both groups (P<0.01,P<0.05).Conclusion Acupuncture based on electric meridian detection is an effective method in treating angioneurotic headache.
