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.

Moving policy and regulation forward for single-use plastic alternatives

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 3, doi: 10.1007/s11783-021-1423-5

Abstract: Single-use plastics are often used once or cannot be reused for extended periods. They are widely consumed with the rapid development of social economy. The waste generated by single-use plastics threatens ecosystem health by entering the environment and ultimately restricts sustainable human development. The innovation of sustainable and environmentally friendly single-use plastic alternative materials and the joint participation of governments, enterprises and the public are promising technologies and management approaches that can solve the problem of single-use plastics wastes. The development of single-use plastic alternative products can be promoted fundamentally only by improving relevant legislation and standards, providing differentiated industrial policies, encouraging scientific and technological innovation and expanding public participation.

Efficacy and safety of perioperative parecoxib for acute postoperative pain treatment in children: a meta-analysis

Xueshan Bu,Lei Yang,Yunxia Zuo

Frontiers of Medicine 2015, Volume 9, Issue 4,   Pages 496-507 doi: 10.1007/s11684-015-0414-y

Abstract:

Perioperative parecoxib administration reduces postoperative pain, opioid consumption, and adverse events in adult patients. However, the efficacy and safety of parecoxib in children remain unclear. This meta-analysis included related published studies to address this concern. Eight databases in the literature until February 2015 were systematically explored to identify randomized controlled trials (RCTs) comparing perioperative parecoxib administration and placebo/standard treatments for acute postoperative pain in children. Primary outcomes were postoperative pain scores and adverse events. The Face, Legs, Activity, Crying, Consolability scale was used to score pain in children younger than 6 years, whereas the Visual Analog Scale was used in children older than 6 years. Secondary outcomes were sedation scores (measured using the Ramsay scale), agitation scores (measured using the Sedation-Agitation Scale), and opioid consumption. The methodological quality of RCTs was independently assessed in accordance with the “Risk of bias” of Cochrane Collaboration. Data were analyzed using Review Manager 5.2. Twelve RCTs involving 994 patients met the inclusion criteria. Compared with children who received placebo treatment, those who received parecoxib demonstrated lower early (2 h) and later (12 h) postoperative pain scores; lower incidence rates of postoperative nausea, vomiting, and agitation; higher early (1 h) postoperative sedation scores; and lower agitation scores. Similarly, children who received parecoxib had lower early (2 h) and later (12 h) postoperative pain scores, lower incidence rates of postoperative nausea and vomiting, and lower early (1 h) postoperative sedation scores compared with those who received standard treatments; however, these children showed no significant difference in agitation scores. Unfortunately, data on the effect of parecoxib on opioid consumption were insufficient. Overall, these results suggested that perioperative parecoxib administration was associated with less acute postoperative pain and fewer adverse events compared with placebo or standard treatments. Parecoxib administration also resulted in less emergence agitation compared with placebo treatment and less excessive sedation concern compared with standard treatments. However, the long-term effects, effects on opioid consumption, and patient satisfaction of parecoxib administration warrant further investigation.
