逻辑链:
KO research--> 女性感受痛楚比男性小&时间长 --> 1 应该给女性服用KO止疼药,给男性服用其他的 2 revalue all medications on women vs men
Based on a latest research towards the result of application of a pain medication, the author concludes that doctors should prescribe kappa opioids to the woman who need pain medication at any time whereas give other painkillers to men, and researchers need to reassess effects of all medicines on both men and women. From my point of view, this cause and effect relationship between the research and the conclusion is somewhat farfetched and untenable as it stands.
To begin with, several unscientific and irregular operations in the whole experiment process make the research lose its power to sustain the conclusion. The first unconvincing factor is the quantity of the participants in each experimental group-- the primary mistake. Strictly speaking, for the purpose of impartiality, an experiment needs to at least use the same number of subjects. Unfortunately, the author does not give any sufficient reason that why they use 28 men versus 20 women in the study. Apart from the unequal number, the second unreliable factor is the women’s reports. Should a rigorous researcher make his judgment only based on such original materials without making a scrutiny into the reports and using any statistical analysis? In fact, that these women feel much less pain than the men is probably their misperception . No evidence reveals that the two groups are set in separate space or the women cannot be influenced by the men or the surroundings. It is highly possible that the extreme distress on the men’s face cause sympathy from the women and thus they made such personal and emotional reports. Third, the reports from the women group also indicate the degree and the duration of their pain, comparing with the men. However, they did not state whether they took any other painkiller besides the kappa opioids or whether they used other kinds of medicines after their wisdom tooth extraction surgery. Maybe other medications actually help the participants reduce the pain or extend the duration time after the tooth operation, rather than the kappa opioids. Therefore, with so many factors which could not be expressed clearly, it is difficult for the audience to judge whether such an unpersuasive research could fundamentally validate the assertion.
Even if kappa opioids does have some positive effect to cure the person who is suffering from the tooth’ pain, it seems not easy to make the conclusion that the women should be prescribed with this kind of drug, whereas men should be given other kinds of pain medication. The first reason is kappa opioids may not have the same effect on the other pains, such as headache, stomachache, muscle strain and so forth, as on the tooth pain treatment. From my perspective, it is better for a doctor to prescribe deferent medicines according to various conditions of his patients. The second point that men should be given other kinds of pain medication is still open to doubt, because the reports in the study is merely from women participants and readers could not find any clue in the argument about the medicine effect from the aspect of men. Therefore, it is entirely arbitrary for the author to make such a subjective affirmation.
Last but not least, in my opinion, it is unnecessary to revalue the effects of all medications on men versus women. From ancient times to the modern period, from east to west, there are Tens of thousands of kinds of medicines in the world. If we reassess the effect of all medications, tremendous human, finance and other resources need to be invested in this ambitious but impractical project, which would absolutely exceed the bearing capacity of our whole society and eventually do harm to ourselves.
To sum up, I agree that doctors should consider different conditions when prescribing pain medications, as the author mentioned at the beginning. Nevertheless, he fails to convince me with a scientific and persuasive research. Moreover, the two assertions he makes at the end of the argument is highly subjective and even unrealistic for the public to make a proper decision. |
