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.

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.

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 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

Objective To understand the actual psychological conditions of pregnant patients with gynecologic malignancies during chemotherapy so as to instruct the nurses to provide individualized psychological care to the patients and their relatives. Method The in-depth interviews were conducted to 7 patients by implementing the phenomenological approach of qualitative study. The acquired data were analyzed. Result The patients experienced four psychological conditions: pessimism about prognosis, anxiety to know more about the chemotherapy and guilty to their family and hope for treatment effect. Conclusion Nurses should pay attention to the psychological conditions of pregnant patients with gynecologic malignancies and help them successfully live through the treatment.

Objective To assess the value of T?SPOT.TB test in the diagnosis of active tuberculosis. Methods The clinical data of 975 hospitalized patients receiving T?SPOT.TB test were collected in our hospital. The clinical information and testing results were analyzed. The receiver operating curve (ROC) was used to determine the optimal threshold of T?SPOT.TB test for differentiating active tuberculosis. Results T?SPOT.TB test results showed that the positive rate was 29.26%for the non?active tuberculosis group(n=793),but was 91.21%for active tuberculosis patients group (n = 182),which indicated that the test had a significant value in active tuberculosis detection(P<0.001). The sensitivity of T?SPOT.TB test was 0.912 and the specificity was 0.707. The detection threshold of T?SPOT.TB was optimized. As the spot?forming count(sfc)of ESAT?6 antigen threshold was 11.5 and that of the CEP?10 threshold was 9.5,the efficiency of T?SPOT.TB test for detection of active pulmonary tuberculosis was the highest. Conclusions T?SPOT.TB test has a good diagnostic performance for active tuberculosis, and it can be further optimized to better serve the clinical practice.
