Methods: Retrospective analysis of 200 cases of postpartum pelvic floor dysfunction patients discharged from the hospital from January 2016 to March 2019 as study subjects who were excluded other underlying diseases and were randomly divided into two groups of 100 cases per group, using electrostimulation biofeedback therapy combined vaginal dumbbell therapy as a treatment group. The treatment of electrostimulation biofeedback therapy in combination with kegel was treated as a control group. Then the curative effects of the two groups were compared and statistically analyzed. Results: There was no significant difference in EMG value of postpartum pelvic floor treatment, type I muscle strength, type II muscle strength, muscle type I fatigue, type II fatigue and POP-Q detection results between the two groups before treatment, p > 0.05. There were significant differences in type I muscle strength, type II muscle strength and muscle type I fatigue between the pelvic floor muscles and the muscles at the end of the treatment day, the sixth month and one year after treatment, p ?There was no statistically significant difference at?the end of muscle type II fatigue?treatment day, p > 0.05;while after the treatment of six months and one year, the difference was statistically significant, p 0.05. In addition, the treatment group and the control group were compared before and after treatment, the difference of myoelectric potential value, pelvic floor muscle type I muscle strength, type II muscle strength, muscle type I fatigue degree, type II fatigue degree and POP-Q test result were significant, and the changes in the indicators before and after treatment in the treatment group were significantly higher than the control group. Comparison of urinary incontinence between the two groups before and after treatment, the difference between pre-treatment and the end of treatment day was not statistically significant, p > 0.05;there was significant difference between half a year and one year after treatment (p 0.05, respectively). Comparing?the satisfaction with sexual life after the time of treatment day, half a year and one year after the end of treatment, the difference was statistically significant (p ?Conclusion: Electrical stimulation biofeedback therapy combined with vaginal dumbbell therapy has a good effect in the treatment of postpartum pelvic floor dysfunction, and it is worthy of popularization and application.展开更多

In this study, droplet digital PCR (ddPCR), an emerging DNA absolute quantification technology, was used to identify single-copy homozygous transgenic lines from a batch of T0 transgenic rapeseed harboring 11 exogenous elements. Copy number of exogenous gene was evaluated in T0 generation based on calculated ratio between transgene and reference CruA gene, single-copy transformants were selected for selfing followed by subsequent zygosity analysis. Single-copy homozygous transgenic plants were successfully screened out in T1 generation by ddPCR.Segregation analysis with T2 seedlings verified that identification results of ddPCR were accurate and reliable. This study provides a novel rapid and accurate method for copy number and zygosity determination in transgenic rapeseed which overcomes disadvantages of traditional Southern analysis and recently developed real-time quantitative method.展开更多

The protection of consumer rights to information as well as the genetically modified orgamisms （GMO） labe-ling polily required analytical methods to determine whether the oils contained genetically modified ingre-dient or not. Polymerase chain reaction （PCR） - based method was used commonly to determine the presence of GMOs. Adulteration attracted peoples concern also. Thus it was crucial that enough DNA ex-tracts can be obtained successfully from oil samples. For the purpose, three DNA extraction methods （modified emulsification method, the kits Wizard Magnetic DNA purification system for food and Nucleospin Food） ,were applied to 3 different grades of rapeseed oil samples. Those methods were compared by the amplification of Brassica napus reference gene CruA using real - time PCR. The results demonstra-ted that both the modified emulsification and the Nucleospin methods were able to extract enough DNA from refined oils. The modified emulsification method was superior to the kit of Nucleospin food due to smaller volume of required sample.展开更多

The study is addressed through an examination of intergenerational influences across the two different cultures. The results of the study lend support to the original approach and also provide an insight look into how reference group influence may vary depending on different culture context.

Galanz is a typical Chinese manufacturer to execute niche strategy. It makes use of labour force advantage, resource advantage and technologist advantage to enter microwave oven market, and it has been one of the most famous manufacture factories in the world. The success of Galanz gives elicitations to other Chinese manufacturers, and it will inspirit more and more manufacturers appear similar as Galanz.展开更多

Therefore, ...To ensure food safety, it's vital to accurately detect genetically modified(GM)ingredient adulteration in food products and effectively detect the adulteration of vegetable oils from GM organisms(GMO). Therefore, it's essential to establish efficient DNA isolation method from vegetable oil. Here, we evaluate 5 DNA isolation methods using 25 commercial vegetable oils produced from soybean, peanut, corn, sunflower, rapeseed as well as blended oils. Quality of isolated DNA was determined by Nanodrop 2000 spectrophotometry. Real-time PCR and universal gene tRNA-Leu was used to assess resolution of methods. Our results showed that only DNA samples isolated by modified emulsification method based on cetyl trimethylammonium bromide(CTAB) were able to amplify t RNA-Leu gene.Moreover, Ct values of species specific endogenous reference genes were greater than 36 in these samples. In summary, CTAB method showed the best resolution on GMO adulteration detection for commercial vegetable oils, especially in fully refined oils.展开更多
