The results showed that the numbers of the heterotrophic bacteria around QPP were much higher than those in unpolluted environments, and the average numbers in QPP Seawater, QPP Sediment, Unpolluted Seawater and Unpolluted Sediment were 5.4×104cfu(mL) -1, 5.0×105cfug -1, 3.0×102cfu(mL) -1 and 1.3×105cfug -1 respectively. Totally, 118 strains were isolated from QPP and 99 of them were Gram-negative. One hundred and twenty one strains were isolated from the unpolluted environments and 104 of them were Gram-negative. All the Gram-negative bacteria belonged to 13 genera. The distribution of the bacteria was varied in different marine environments. The results showed that the unpolluted marine environments contained much more Vibrio than seawater and sediment around QPP.展开更多

The result shows that the populations of the heterotrophic bacteria are heavier in summer and autumn than those in winter and spring. The average populations in seawater, sediment, the surface of seaweed and the surface of fish are 1.4×10 4 cfu mL -1, 5.4×10 6 cfu g -1, 1.5×10 6 cfu g -1 and 1.8×10 3 cfu cm -2, respectively. A total of 301 strains were isolated, among them 259 were Gram-negative. All the Gram-negative bacteria belong to 13 genera and some genera of Enterobacteriaceae. The communities of bacteria are slightly different among the samples. In the body surface of fish, Genus vibrio is dominant. In the remaining samples, dominant genus is Aeromonas.展开更多

Establishing a unified, standardized and sound social security system not only reflects the basic rights and interests of the broad masses of people, but also reflects the basic requirements of social security management. It is also the basic content of the countrys promotion of stable construction. At present, Dantu District Peoples Social Security Bureau is mainly responsible for handling social insurance such as old-age care, work-related injuries, unemployment, etc. In order to strengthen the construction of social security system in Dantu District and further coordinate the all-round economic and social development of urban and rural areas, Dantu District Peoples Social Security Bureau has set up a special research group to investigate and study the construction of social security system in Dantu District. Based on the basic situation of social security system construction in Dantu District, this paper puts forward relevant work suggestions.展开更多

Laparoscopic pyeloplasty （LP） is not widely prevelant because of the technically challenging nature and it represents the gold standard for UPJO only in expert hands. To overcome some difficulties and technical challenges encountered during pure laparoscopic pyeloplasty, we designed a set of new instruments and assessed them using porcine model.展开更多
