How Dragonflies Mate
By Debbie Hadley
Dragonfly sex is a rough and tumble affair. If you've ever seen a pair of
mating dragonflies in the throes of passion, you know that their sexual
coupling requires the flexibility and acrobatic skill of a Cirque de Soleil
performer. Females get bitten, males get scratched, and sperm winds up
everywhere. These strange mating habits have survived millions of years o... 阅读全帖 |

在这四个方面，我们有没有可能做得更好？我认为，都有。
这几天，已经有很多媒体报道从各个角度、特别是一线医护人员的直观视角，总结过这
次应对新冠肺炎疫情的过程中出现的、特别是早期疾病发现和预警过程中的一些问题。
我首先得强调一句：在疫情的危急时刻大家都希望听好消息、正能量，这个没错，我也

一般黑人说：“Big boobs get him going"
我们nerd会说:"
Two pronounced mammary glands highly positioned on the well-nutrition-ed
adult female thorax sends bold mating signals to him,
which enables hormonal changes in the brain,
and switch on the courting behavior downstream the neural pathway.

cholecystitis too.
If PE is still a clinical suspicion, CT of thorax PE protocol is preferred
over V/Q scan, since the nuclear tracer Tc-99m MAA is excreted to the
bladder and has more radiation to the fetus. But we need cover her tummy
with lead apron when performing the CT.
I have a question about D-dimer, I have seen people order that for PE, but
is it specific enough? |

发帖数: 367 | 28 我们journal club的时候讨论过同样的文章和有关的话题，大家基本认为写CT PE
protocol没有V/q更好的作者们（有核素背景的）都practice在理想真空。
首先他们说的孕妇血流量大，IVC导致造影剂不均匀什么的，比较不让我们信服。首先
，同一个人在hydration情况不相同的时候，IVC都能很不相同，脱水时IVC可以变得很
扁，而病人在急诊给了不少fluid之后，好多人都已经是fluid overload。在做
pulmonary CTA 时，用的是18g针头加上power injection，扫描的timing是影像质量的
最重要因素。当有右心衰竭的时候，造影剂会返流到IVC甚至肝静脉，这也许是IVC在PE
CTA是最常在报告里提到的。我们还从来不用因为病人血流量或者hydration status担
心过造影质量, I do not buy it at all. 这点百分百同意dreamlady说的。
其二，对孕妇胎儿辐射的问题。当你有孕妇在你面前要做r/o PE检查时，病人和放射科
都会同意选辐射少的。v/q究竟比CTA精确多少能值得冒险去做放射线多的检查呢... 阅读全帖 |
