The effectiveness of contractions was usually judged from the following aspects: ** 1. From the perspective of treatment purposes ** 1. ** Used for inducing labor ** - For situations where the delivery process needs to be initiated or accelerated, drugs that can effectively cause the uterus to contract regularly and rhythmically, and the intensity and frequency of this contraction gradually increase to promote the smooth delivery of the fetus can be considered effective. For example, a small dose (2 - 5U) of pitocin could enhance the rhythmic contraction of the smooth muscle of the uterus, which could be used to initiate and enhance the delivery process. 2. ** For the prevention and treatment of post-natal hemorrhage ** - Medicines that could quickly cause the myometrial muscle to contract and mechanically compress the blood vessels in the muscle fibers to stop bleeding were effective. For example, a large dose of pitocin (5 - 10U) could cause the tonic contraction of the smooth muscle of the uterus. It was used to prevent and treat the fatigue of the uterus and to promote the reduction of post-natal hemorrhage in the third stage of labor. There were also synthetic long-acting inotocin-like substances such as carbetocin-like, which combined with the receptor of the pitocin and had a positive effect in the prevention and treatment of post-natal hemorrhage. 3. ** Used to suppress contractions for threatened premature labor ** - If it was used to suppress the contraction of the uterus to prolong the pregnancy period (such as between 20 - 34 weeks of pregnancy), it could successfully suppress the contraction of the uterus, and it was effective to complete the treatment of steroids to promote the maturity of the fetal lung or to buy time for the fetus to be transported in the womb. - For example, atosiban had a good effect in prolonging the duration of pregnancy. It played a role by suppressing the reaction of the uterus smooth muscle cells induced by pitocin. It was recommended to be the first choice in twin pregnancy, pregnancy complicated with heart disease, hypertoxicity, high blood pressure, kidney disease, etc.; Preeclampsia, diabetes complicated with pregnancy, unstable blood sugar control in Gdm; Prenatal bleeding was not much, and there were conditions for continuing pregnancy. ** 2. From the perspective of the drug's mechanism of action ** 1. ** Affects ion channels ** - For example, the calcium channel blocking agent nifedipine, after entering the body, blocks the calcium channel on the surface of the muscle cell membrane, causing the ions on the surface of the muscle cell membrane to lose the flow channel, thereby reducing the concentration and concentration of calcium ions, which plays a role in relieving the contraction of the uterus. It is effective if it can achieve the expected effect of restraining contractions at the appropriate dosage. 2. ** Acting on the receptor ** - For example, ritodrine, a beta2-adrenoceptor stimulant, directly acted on the beta2-adrenoceptors in the smooth muscle layer, bronchi, and blood vessel smooth muscle to affect the contraction of the uterus. If it could be used in accordance with the indications (mainly for pregnant women with signs of premature birth after 20 weeks of pregnancy), it would be an effective drug to suppress contractions. - Atosiban, a receptor antagonist for the human body, could regulate the contraction of the uterus through the inhibition of the receptor. It would be effective if it could achieve the purpose of suppressing contractions and prolonging the pregnancy period in the pregnancy related situations. 3. ** Affects the synthesis of hormones or related substances ** - Progestogen drugs such as dydrogone tablets, allylestriol tablets, etc., by suppressing the excitatory effect of estrogens on the myometrial, reduce the sensitivity of the myometrial to various stimulations, thereby suppressing the contraction of the uterus. At the same time, they affect PG synthesis, inhibit the start of the contraction of the uterus, and make the uterus static. When they meet their indications (such as early threatened abortion, late threatened abortion, repeated pregnancy after repeated abortion, assisted pregnancy cycle, etc.), they can effectively suppress the contraction of the uterus. - Prostaglandin-synthesizing-ase Inhibition Indometacin. Prostaglandin-synthesizing-ase is the key catalyst for converting arachidonic acid into a antagonist, and the antagonist has the effect of stimulating the uterus. This drug suppresses the contraction of the uterus by suppressing this catalyst. It is effective in patients who are less than 32 weeks pregnant and are suitable for tocoly-preserving treatment. Since there were no pictures related to the judgment of the effectiveness of the contractile drug, the above is the judgment of the effectiveness of the contractile drug from the perspective of the treatment purpose and mechanism of action.

Bears appear, bald men are beaten up by animals

In Bear Haunt, Bald Qiang was often beaten up by animals. In terms of physical conditions, Big Bear and Big Bear were adult bears with great strength, while Baldy Qiang was a short human. There was a natural physical difference between them. In terms of the plot setting, although Baldy Qiang had a hunting rifle, there were two settings that were not conducive to his victory. One was that his marksmanship could not hit animals such as Big Bear and Big Bear. Even if his marksmanship was not weak, once the muzzle was pointed at Big Bear and Big Bear, he would not be able to hit them even if they were close to his face. The second was that at the critical moment, his gun must be out of bullets. Moreover, Big Bear also had a good brain. When Bald Head Qiang was at his peak, Big Bear could often think of a way to win when Big Bear and Big Bear were defeated in a head-on battle. For example, he could first use kindness to break Bald Head Qiang's wariness and then attack when he was unprepared. In addition, Baldy Qiang was kind by nature and had never been ruthless to Big Bear and Big Bear. Even if he had the ability to subdue Big Bear and Big Bear, he would not hurt them, so he was often beaten up by Big Bear and Big Bear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

This time, they asked questions such as who was in the poem and where they saw the moon. Ask further questions about how different characters see the moon, such as where the bird sees the moon and what it says. - On the basis of the child's understanding of the content of the poem, lead the child to recite the poem with emotion. Pay attention to the gentle tone and the use of the measure word. At the same time, the children were organized to discuss some of the images in the poem, such as explaining why there was a moon hanging on the treetops (guiding the children to understand that the moon's light on the treetops looked like the moon hanging), and let the children do the action of "hanging" and then say a sentence with "hanging". - If it was a story-based teaching (using "Finding the Moon" as an example): - The teacher first showed a paper moon to arouse the interest of the children in listening to the story.

For example, children should imagine where the moon might appear according to their own experience and express it in the corresponding language. #(III) End 1. The teacher summarized the content of this lesson, reviewing the children's learning of moon-related poems or stories, emphasizing key knowledge (such as the use of measure words, the reflection of the moon, etc.). 2.
