Objective To investigate the epidemiology of 10 000 patients with mammary gland disease.Methods 10 000 mammary gland disease cages during 1987~2006 in Yangquan Tumor Institute were collected,all patients had integrity case files and were diagnosed by molybdenum target radiography,near infrared ray,sonography,aspiration-needle biopsy or polyrrhea smear examination.Results In 8919 outpatient treated cases,7493 suffered cyclomastopathy(84%).1081 cases were inpatient cared(11%),the top five mammary gland disease are:breast cancer 342 cases,cyclomastopathy 252 cases,adenofibroma 104 cases,intraductal papilloma 86 cases and ductal ectasia 76 cages.For breast cancer patients,there were 125 cases during 1987~1996,3 were 21~30 years old and 23 were 31~40 years old.The number during 1997~2006 was 217,24 were 21~30 years old and 69 were 31~40 years old.Conclusion In 10000 cases,there are 7745 cyclomastopathy patients(77.45%)which takes the first place.Especially for 342(3.42%)breast cancer cases,the incidence grew up and patients age was much younger.

Objective To establish a novel method by integrating immunomagnetic bead enrich-ment with immunochromatography for the detection of influenza A virus. Methods The immunomagnetic beads were prepared by using EDC/NHS method and then coupled with monoclonal antibodies against influ-enza A virus. A direct immunomagnetic beads-based immunochromatography for the detection of influenza A virus was developed by using double-antibody sandwich method and immunochromatography, which was fur-ther combined with immunomagnetic separation to establish the novel integrated method of immunomagnectic bead enrichment and immunochromatography. Clinical throat swab samples collected from patients with influ-enza A virus infection and healthy subjects were analyzed by the novel method and the results were compared with those by using the conventional colloidal gold immunochromatography to evaluate the specificity, sensi-tivity and positive coincidence rate of this established method. Results The direct immunomagnetic beads-based immunochromatography and the colloidal gold immunochromatography showed no significant differences in specificity and sensitivity and could be used to identify influenza A virus-positive samples with cycle threshold ( Ct) values less than or equal to 22 obtained by real-time PCR assay. The integrated method could identify positive samples with Ct values less than or equal to 28, indicating that the novel method was more sensitive. Conclusion The novel method by integrating immunomagnetic bead enrichment with immunochroma-tography was successfully established and suitable for the rapid and on-site detection of influenza A virus.

Objective To observe the effect of Compoud Qingqin Liquids on renal function of rat model of uric acid nephropathy, and to discuss its protection of renal function. Methods The rat model was induced by gavaging adenine and feeding yeast. SD rats were randomly divided into control group, model group, positive group, and high-, medium-, low-dose groups of Chinese medicine. Blank control group and model group were daily gavaged with distilled water, positive control group was daily gavaged with allopurinol by 9.33 mg/kg, and high-, medium-, low-dose group of Chinese medicine was daily gavaged with Compound Qinggin Liguids by 3.77, 1.89, 0.09 g/(kg·d) respectively for 6 weeks. General condition of rats were observed, renal pathological changes were observed with light and electron microscope. Urine protein concentration, blood uric acid, blood urea nitrogen, creatinine and kidney weight index were respectively tested before and after treatment. Results There were no significant differences in eating, drinking and body weight between before and after modeling. Compoud Qingqin Liquids can obviously decrease the concentration of urine protein, blood uric acid, serum creatinine, blood urea nitrogen, and kidney weight index (P<0.05) of rats with uric acid nephropathy. Renal tubular epithelial cells atrophy and renal interstitial fibrosis of high-dose group of Chinese medicine were not evident. Conclusion Compoud Qingqin Liquids can protect the rats renal function against uric acid renal injury.

Abstract
Airborne microorganisms, especially pathogenic microorganisms, are easily transmitted through dust and droplets, leading to various infectious diseases. The study summarizes the status of airborne microbial pollution, potential exposure levels, particle size, and species distribution of microorganisms, discusses the impact of airborne microorganisms on human health, and analyzes specific factors affecting campus air microorganisms from four aspects:climate, anthropogenic factors, time, and space, to provide a scientific basis for formulating effective improvement measures, improving air quality and safeguarding the health of teachers and students.

Objective:
To understand the viral etiology of a clustered case of human infection outbreak in the middle school of Huai’an city.
Methods:
Nasopharyngeal swab samples from patients were collected and rapidly detected by Real-time RT-PCR and the target virus isolated in cells. Furthermore, HA1 segments of target virus were amplified by RT-PCR and sequenced. The genetic and phylogenetic analysis based on HA1 genes was computed.
Results:
Influenza A(H1N1)pdm09 viral nucleic acid in 11 nasopharyngeal swab samples from patients in the outbreak were positive. Compared to the vaccine strains A/California/07/2009, the Huai’an isolates, nucleotide identity was 97.7%-98.1%, and amino acid identity was 96.6%-97.4%. Phylogenetic analysis of HA1 segment sequences indicated that the Huai’an strains from the outbreak were related closely to the viruses isolated in the year of 2014. Sequence analysis indicated that the Huai’an isolates had no amino acid substitution in the receptor binding sites and glycosylation sites, while in the Ca1 of antigenic determinant of HA1 the Huai’an isolates had an amino acid substitution of S for T at 220.
Conclusions
The pathogen of the clustered case of human infection was Influenza A(H1N1)pdm09 virus. Though the Huai’an isolates had one animo acid substitution in the Ca1 of antigenic determinant, the antigenicity characteristic remained unchanged.
