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 study the value of insulin like growth factor binding protein-1 of cervicovaginal secretion in the delayed pregnancy termination. Methds Phosphorylated isoforms of IGFBP-1 in cervicovaginal secretion of 202 delayed pregnant women were measured by immmmunochromatography. Results In the IGFBP-1 positive group. The rate of successful pregnant termination in three days was 91 2%, while in IGFBP-1 negative group, the rate of that was 41 8%..There was statistically significant diference in the rate of successful pregnant termination between the two groups(P

Objective To investigate the effects of dexamethasone on the growth of cervical cancer induced by HeLa cells transplanted into BALB/c mice. Methods HeLa cells were inoculated subcutaneously into BALB/c mice. Dexamethasone (15 mg?kg-1?d-1) was injected intraperitoneally from the 6th or the 16th day after tumor inoculation for 10 days continuously. Diameter of tumors was measured every two or three days. Apoptotic bodies were observed by transmission electron microscopy and counted by TUNEL. Results Dexamethasone repressed the growth of cervical cancer and induced tumor cell apoptosis, but the tumor volumes were of statistical difference between the two groups of different injection start time (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.

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.
