Analysis on reasons of unwanted pregnancy by women of child-bearing age and its strategies

Wang Daiquan,Liu Changyan,Xiang Qiong and Ma Daici

Strategic Study of CAE 2014, Volume 16, Issue 5,   Pages 11-15

Abstract:

This paper makes relative questionnaire from cluster sampling of induced abortion from Jan. 2011 to May 2013 as well as looking up medical records to analyze reasons of unwanted pregnancy. Among 1 360 cases of unwanted pregnancy，21.62 % are unmarried，78.38 % are married；age distribution ranges between 20～39（73.82 %）；pregnant time distri-bution is between the second and third pregnancy（57.87 %）；44.34 % is due to contraceptive failure，55.66 % is due to no contraceptive use；IUD accounts for 10.51 % of choice of contraceptive measures，use of condoms is 10.51 %，contraceptive is 8.24 %，external use is 6.62 %， other mean is 8.46 %. The main reasons of unwanted pregnancy are due to taking chances with no contraceptive use or no contraceptive use after removal of IUD；98.90 % of interviewed subjects know contraceptive knowledge，15.37 % know emergency contraception，18.38 % know the necessity of contraception measures for nursing mothers. Married people get information of the contraception knowledge mainly from medical workers，family planning cadres，publicity materials. More farmers and migrant workers are willing to get free services than urban residents，government employees，commercial service personnel and other migrants.

Interspecies transmission and evolution of the emerging coronaviruses: perspectives from bat physiology

Baicheng HUANG, Kegong TIAN

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 2,   Pages 218-226 doi: 10.15302/J-FASE-2020324

Abstract:

Emergent coronaviruses (CoVs) such as SARS-CoV and MERS-CoV have posed great threats to public health worldwide over the past two decades. Currently, the emergence of SARS-CoV-2 as a pandemic causes greater public health concern. CoV diversity is due to the large size and replication mechanisms of the genomes together with having bats as their optimum natural hosts. The ecological behavior and unique immune characteristics of bats are optimal for the homologous recombination of CoVs. The relationship of spatial structural characteristics of the spike protein, a protein that is critical for recognition by host receptors, in different CoVs may provide evidence in explaining the coevolution of CoVs and their hosts. This information may help to enhance our understanding of CoV evolution and thus provide part of the basis of preparations for any future outbreaks.
