Objective To control the hazardous effects of excessive arsenic in drinking water on human health. Methods The experiment on the removal of excessive arsenic from drinking water by electric absorb technology (EST) was performed. Results The pilot experiment and experiment in situ showed that, after treatment by EST, the contents of arsenic in source water(0.06-0.33 mg/L) decreased to the levels of

Objective: To confirm that the antiserum induced by short peptide in the region of AA 448-477 at HPV16 L1 C-terminal can respond with many types of HPV L1. Methods: This sutdy synthesized a short peptide containing the conserved sequence of HPV L1 and immunized animal with the synthetic peptide to obtain the polyclonal antiserum. The type of HPV in clinical specimens, such as cervical cancer and condyloma acuminatum tissues, was identified by PCR. ELISA, Western blotting, and inummohistochemistry were used to determine whether the anti-serum of the short peptide could react with different types of HPV-positive specimens. Results: ELISA assay showed that the reaction between antigen and antibody was positive in HPV6, 11, 16, and 18 and other HPV-positive clinical specimens. Western blotting revealed that there was a strip at 56 kDa in all types of HPV-positive clinical specimens, but there was no strip in HPV-negative clinical specimens. Immunohistochemistry analysis demonstrated that the histological reaction had varying features in different clinical specimens. The positive-reaction appeared only in the epithelium tissues, which was regional and had apparent borders. Conclusion: This study confirms that the common conserved sequence really has HPV L1 common epitope. Its anti-serum can respond with many types of HPV L1. These findings provide an important basis for further researching a broad-spectrum HPV L1 vaccine or publicizing broad-spectrum HPV detection kits.

Objective To analyze the allergens detection in asthmatic infants and young children. Methods The specific IgE test and allergens screening test were conducted in 243 infants and young children with whooping diseases including asthmatic bronchitis, asthmatic pneumonia and asthma by skin prick test and Pharmacia UniCAP test. Results 1. Food allergen was the allergen detection most frequently in infants(P = 0.03). The proportion of aeroallergens increased significantly with age (positive rate:67. 2%). Milk and egg white was the main food allergen detection in infants and young children,and the main aeroallergen detection was house dust mite. 2. The allergen - specific IgE test using UniCAP test system was more accurate than skin prick test. Conclusions The infants are more susceptible to food hypersensitivity; the increasing opportunity of aeroallergen exposure may lead to a higher prevalence of aeroallergens in young children. UniCAP system is more accurate than other methods.

In recent years,a large number of researches show that the tumor related gene promoter hypermethylation is an important reason of esophageal adenocarcinoma and closely associated with the differentiation,invasion,metastasis,staging and prognosis of tumors.It might be used as a neww target for the clinical detection and therapy of esophageal adenocarcinoma.

OBJECTIVE: To analyze the use situation and trend of cardiovascular and cerebrovascular drugs during 2007～2009 in a military sanatorium, and provide reference for the rational use of cardiovascular and cerebrovascular drugs and its essential medicines. METHODS: Cardiovascular and cerebrovascular drugs in the rehabilitation center during 2007～2009 were analyzed statistically in the respect of category, consumption sum and DDDs. RESULTS: The consumption sum and DDDs of cardiovascular and cerebrovascular drugs were increasing in the past three years. And its essential drugs account for 94.8%.The most widely used drugs were cerebrovascular drug, brain metabolism drug, nootropics and antihypertensive drugs. Oxiracetam and Xueshuantong were widely used cerebrovascular drug, brain metabolism drug and nootropics. Amlodipine were widely used antihypertensive drugs in the clinic. CONCLUSION: Cardiovascular and cerebrovascular drugs and its essential drugs were characterized with complex classification, numerous categories, extensive application and potential market demand, which require rational use of drug should be strengthened.

Objective To study the perioperative management of abdominal surgery in patients aged over 80 years. Methods The cliuical data of 25 patients aged over 80 years undergoing abdominal surgery were analysed retrospectively. Results Of the 25 patients, 8 subjected to biliary surgery, 13 gastiic cancer or cardiac cancer surgery, 1 esophageal cancer surgery, 3 intestinal surgery. 24 patients(96%) were cured; one died postoperalively.Conclusions In over aged patieats, they have more coexite diseases, and more postoperative complications, so extensive perioperative management, choice of selective operation, reducing of emergent operation, and giving albumin to help the recovery of tissues are essential.

Objective To investigate the changes of expressions of axon guidance molecule Sema3F and its receptor Np2 in hippocampus of temporal lobe epilepsy(TLE)rat.Methods Rats were injected with Lithium-chloride,Pilocarpine intraperitoneally to establish TLE model.The Sema3F mRNA,Np2 mRNA and protein in areas CA1,CA3 and dentate gyrus(DG)of hippocampus at different time were detected by immunohistochemistry and in situ hybridization for TLE models.Further,they were compared with normal control group.Results Compared with normal control group,the expressions of Sema3F mRNA,Np2 mRNA and protein in areas CA1,CA3 significantly decreased(P

By means of correlative analysis of critical care air transportation management between China Air Force and United State Air Force,five areas of importance are discussed in this paper,such as the management model of strategies for air transportation,critical care team personnel composition,professional training mechanism,normalization and standardi-zation of operation process,and intensive application of new technology and equipment.
