Balb/c mice were immunized by intraperitoneal iniection of group A erythrocytes. Immunized spleen cells were fused with Sp2/0 murine myeloma cells from the solid tumour. After 10~15 days of incubation at 37℃ CO_2, the supernatants were screened for the agglutinabal antibodies. Three hybridoma cell lines secreting high titer and specific monoclonal anti-A antibodies were established.These hybridoma cells have the ability of constant seceting antibodies which belong to the IgM class. The specificity monocloal anti-A sera was the same as the human anti-A sera.

Objective To evaluate the clinical application of superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage. Methods The iatrogenic renal hemorrhage in fifteen patients was first demonstrated by renal arterigraphy to diagnose the rupture site and degree of injury. And then they were treated by percutaneous catheterized superselective renal arterial embolization through guidance of guide wire. Results In all 15 patients, the occlusive ruption of bleeding arteries and disappearance of extravasation staining were found after the superselective catheterized renal arterial embolization. Clinically, the bloody urine turned clear without macroscopic hematuria during 1-3 days in all patients after the procedure. Conclusions Superseclective renal arterial embolization treatment signified a less invasion, less complications, good hemostatic efficacy, and maximal preservation of renal tissue and function for iatrogenic renal hemorrhage. The treatment is worthy to be recommended.

Abstract: To investigate the distribution of avian influenza virus in environmental samples from live poultry markets (LPM) in China, samples were collected and tested by nucleic acid during 2009-2013 season. Each sample was tested by real-time RT PCR using flu A specific primers. If any real-time PCR was positive, the sample was inoculated into specific-pathogen-free (SPF) embryonated chicken eggs for viral isolation. The results indicated that the positive rate of nucleic acid in enviromental samples exhibited seasonality. The positive rate of nucleic acid was significantly higher in Winter and Spring. The positive rate of nucleic acid in LPM located in the south of China was higher than in northern China. Samples of Sewage for cleaning poultry and chopping board showed that higher positive rate of nucleic acid than other samples. The Subtype identification showed that H5 and H9 were main subtypes in the enviromental samples. Viral isolation indicated H5 subtypes was more than H9 subtypes between 2009 and 2013 while H9 subtypes increased in 2013. Our findings suggested the significance of public health based on LPM surveillance and provided the basis of prevention and early warning for avian flu infection human.

OBJECTIVETo compare two equations for calculating glomerular filtration rate (GFR) in the evaluation of the prevalence of chronic kidney disease (CKD) and the risk factors of CKD in urban healthy population.
METHODSA total of 40377 subjects (24164 males and 16213 females) participated in this study. Body height, weight and blood pressure were measured, and morning urine and venous blood samples were collected for routine urine and blood tests with measurements of blood glucose, total cholesterol, high density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine and uric acid.
RESULTS AND CONCLUSIONUsing Japanese CKD Epidemiology Collaboration (J-EPI) equation and Chinese modified Modification of Diet in Renal Disease (C-MDRD) equation, the prevalence of CKD calculated was 3.9% and 6.3% in this population, respectively. The independent risk factors of CKD included an age over 60 years, high uric acid, and high blood glucose.

To assess relationships between xanthine oxidase (XOD) and nephropathogenic infectious bronchitis virus (NIBV) infection, 240 growing layers (35 days old) were randomly divided into two groups (infected and control) of 120 chickens each. Each chicken in the control and infected group was intranasally inoculated with 0.2 mL sterile physiological saline and virus, respectively, after which serum antioxidant parameters and renal XOD mRNA expression in growing layers were evaluated at 8, 15 and 22 days post-inoculation (dpi). The results showed that serum glutathione peroxidase and superoxide dismutase activities in the infected group were significantly lower than in the control group at 8 and 15 dpi (p < 0.01), while serum malondialdehyde concentrations were significantly higher (p < 0.01). The serum uric acid was significantly higher than that of the control group at 15 dpi (p < 0.01). In addition, the kidney mRNA transcript level and serum activity of XOD in the infected group was significantly higher than that of the control group at 8, 15 and 22 dpi (p < 0.05). The results indicated that NIBV infection could cause the increases of renal XOD gene transcription and serum XOD activity, leading to hyperuricemia and reduction of antioxidants in the body.

Google Flu Trends (GFT) was the first application of big data in the public health field. GFT was open online in 2009 and attracted worldwide attention immediately. However, GFT failed catching the 2009 pandemic H1N1 and kept overestimating the intensity of influenza-like illness in the 2012-2014 season in the United States. GFT model has been updated for three times since 2009, making its prediction bias controlled. Here, we summarized the mechanism GFT worked, the strategy GFT used to update, and its influence on public health.
