A sandwich format immunochromatographic assay for detecting foot-and-mouth disease virus (FMDV) serotypes was developed. In this rapid test, affinity purified polyclonal antibodies from Guinea pigs which were immunized with sucking-mouse adapted FMD virus (A/AV88(L) strain) were conjugated to colloidal gold beads and used as the capture antibody, and affinity purified polyclonal antibodies from rabbits which were immunized with cell-culture adapted FMD virus (A/CHA/09 strain) were used as detector antibody. On the nitrocellulose membrane of the immunochromatographic strip, the capture antibody was laid on a sample pad, the detector antibody was printed at the test line(T) and goat anti-guinea pigs IgG antibodies were immobilized to the control line(C). The lower detection limit of the test for a FMDV 146S antigen is 11.7ng/ml as determined in serial tests after the strip device was assembled and the assay condition optimization. No cross reactions were found with FMDV serotype C, Swine vesicular disease (SVD), Vesicular stomatiti svirus (VSV) and vesicular exanthema of swine virus (VES) viral antigens with this rapid test. Clinically, the diagnostic sensitivity of this test for FMDV serotypes A was 88.7% which is as same as an indirect-sandwich ELISA. The specificity of this strip test was 98.2% and is comparable to the 98.7% obtained with indirect-sandwich ELISA. This rapid strip test is simple, easy and fast for clinical testing on field sites;no special instruments and skills are required, and the result can be obtained within 15 min. To our knowledge, this is the first rapid immunochromatogarpic assay for serotype A of FMDV.

OBJECTIVE:
To observe the expression of aquaporin 4 (AQP4) in diffuse brain injury (DBI) of rats and to explore the corresponding effect of AQP4 for brain edema.
METHODS:
The rat model of DBI was established using Marmarou's impact-compression trauma model. Brain water content was measured by dry-wet weight method. Blood-brain barrier permeability was evaluated by Evans blue (EB) staining. Immunohistochemical method was used to observe the expression of AQP4.
RESULTS:
Brain water content increased after 3 h and peaked at 24 h after DBI. Brain EB content significantly increased and peaked at 12 h after DBI. The expression of AQP4 significantly increased after 3 h and peaked at 24 h after DBI, and the number of AQP4 positive astrocytes increased.
CONCLUSION
The increment of the permeability of blood-brain barrier and the expression of AQP4 may contribute to the development of brain edema in rat DBI. The change of AQP4 expression in astrocytes may also contribute to determine DBI.

Familial isolated pituitary adenoma (FIPA) is an autosomal dominant disease, characterized by low penetrance, early-onset disease, more invasive tumor growth, as well as somatotroph and lactotroph adenomas in most cases. It has been indicated that the aryl hydrocarbon receptor interacting protein (AIP) gene is a tumor suppressor gene. Many heterozygous mutations have been discovered in AIP in about 20% of FIPA families. However, the exact molecular mechanism by which its disfunction promotes tumorigenesis of pituitary is unclear.

OBJECTIVETo compare the safety of intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rtPA) in ischemic patients under the guidance of CT and multi-mode MRI.
METHODSThe clinical, laboratory, and radiologic data from 113 consecutive hyperacute ischemic patients who received intravenous rtPA therapy from June 2009 to October 2011 was retrospectively reviewed. The rate of hemorrhagic transformation (HT) and the clinical outcome between CT and multi-mode MRI was compared. Etiological subgroups were classified according to Chinese ischemic stroke subclassification (CISS).
RESULTSAmong 113 patients treated with intravenous rtPA, the mean age was 66 ±12 years, 74(65.5%) were man, the pretreatment National Institutes of Health Stroke Scale score (NIHSS) was 12.4 ±6.5, and time from symptom onset to therapy was 259.7 ±131.7 min. Postlytic radiological HT was found in 34 patients (30.1%). Symptomatic ICH occurred in 9 patients (8%). Logistic regression analysis suggested that multi-mode MRI was an independent predictor of reduced risk of HT.
CONCLUSIONThe risk of hemorrhagic complications is lower in patients receiving intravenous thrombolytic therapy with rtPA guided by multi-mode MRI than those guided by CT scan.

The safety of Chinese patent medicine has become a focus of social. It is necessary to carry out work on post-marketing clinical safety evaluation for Chinese patent medicine. However, there have no criterions to guide the related research, it is urgent to set up a model and method to guide the practice for related research. According to a series of clinical research, we put forward some views, which contained clear and definite the objective and content of clinical safety evaluation, the work flow should be determined, make a list of items for safety evaluation project, and put forward the three level classification of risk control. We set up a model of post-marketing clinical safety evaluation for Chinese patent medicine. Based this model, the list of items can be used for ranking medicine risks, and then take steps for different risks, aims to lower the app:ds:risksrisk level. At last, the medicine can be managed by five steps in sequence. The five steps are, collect risk signal, risk recognition, risk assessment, risk management, and aftereffect assessment. We hope to provide new ideas for the future research.

OBJECTIVETo explore the semen quality of the workers exposed to the xenoestrogen bisphenol A (BPA) was explored.
METHODSA cross-sectional study of 20 BPA exposed and 16 control workers with similar age, physical activities was performed. Tests included quantifying BPA in blood samples and investigating the quantity and quality of semen. Semen parameters were determined with the method recommended by WHO.
RESULTS94.4% exposed workers were found BPA in blood, and the median was 101.94 microg/L. However, only 18.8% control subjects were found BPA in blood, and the median level was 0 microg/L. The sperm density of exposed workers [(68.65 +/- 44.00) x 10(6)/ml] was significantly lower than that of control [(118.56 +/- 98.36) x 10(6)/ml]. Relationship analysis showed the positive relationships (r = 0.44, P < 0.01) between the sperm with quick forward progression and BPA level in blood, negative relationships between the percentage of normal sperm and BPA level in blood (r = -0.62, P = 0.01).
CONCLUSIONBPA could affect the sperm density, and may influence the semen quality. More research should be performed on the effect and the mechanism of BPA on man.
