妊娠期肝内胆汁淤积症(intrahepatie eholestasis of pregnancy,ICP)特发于妊娠中晚期,是以皮肤瘙痒、肝功能异常为主要临床表现的妊娠并发症,对胎儿生长造成较大影响。普遍认为其发病与妊娠雌激素升高有关,过高的雌激素可通过垂体轴影响甲状腺激素的分泌。国外学者研究发现,孕妇甲状腺激素水平异常可能是ICP的病因之一。血清甘胆酸(CG)普遍认为是诊断ICP的特异性指标之一。本文通  相似文献

The two week period that stretches between the absorption of gametocytes from a malaria patient by a mosquito and the subsequent injection of sporozoites in another human host is a most fragile segment of the malaria cycle. There is non-randomness in the blood meal choice of anopheline vectors. Manipulations of the host by the parasite to satisfy the preferences of the vector might have contributed to the robustness of the malaria cycle. Indeed, although gametocytes do not directly cause symptoms, the acute and chronic clinical manifestations caused by asexual forms seem to be organized around their transmission: fever patterns and behavior modification, anemia and thrombocytopenia converge towards making malarious individuals a preferred and safer source of blood for the vector than non-malarious individuals. Malaria symptoms offer the vector its favorite cues: increased skin temperature, increased lactates, sweating, and CO(2) expiration. In addition, this tempting menu seems easier to absorb because of thrombocytopenia and reduced blood viscosity during anemia, and because behavior modification reduces mosquito avoidance and the risk of dying. The attractive cues may be characteristic symptoms of malaria but also slight infraclinical changes that mostly go unnoticed by the doctor but not by the vector. The manifestations of malaria are often seen as adaptive for the host, this article argues that on average they may also be adaptive for malaria parasites. Examining malaria as the extended phenotype of Plasmodium leads to new research questions.  相似文献

Background

In total knee arthroplasty (TKA), the position of the patellar component can affect patellar tracking. However, the patellar component cannot always replicate the original high point of the patella because of anatomical variance. This study investigated whether altering the highest point of the patella can affect outcomes of primary TKA, especially in patients having a patella with a far-medialized median ridge.

Methods

A retrospective review was performed for 177 knees (143 patients) treated with primary TKA between July 2011 and March 2014. Group 1 (34 knees) had the patellar component displaced over three millimeters from the median ridge, while Group 2 (143 knees) had the patellar component placed on the original median ridge position. The one-year follow-up outcomes were reviewed, including: patellar tilt angle, Knee Society Score, Feller Patellar Score, and modified Kujala Anterior Knee Pain Score.

Results

Mean (± standard deviation) displacement of the patellar component in Group 1 was 3.97 ± 0.97 mm lateral to the original position of the median ridge, with a significant decrease in lateral patellar tilt angle (P < 0.001). Lateral patellar tilt showed a positive correlation with the medialization of the patellar component (P < 0.001, r = 0.401). Ability to rise from a chair was better in Group 1 (P = 0.025). There were no other between-group differences in other clinical outcomes.

Conclusions

There should be no need for the patellar component to replicate the original highest point of the native patella in primary TKA.  相似文献

The reproduction costs to a human mother are different if she has a son as opposed to a daughter. According to the Trivers-Willard hypothesis, evolution should promote those females who, having the ability to invest in the more expensive sex, are also able to adjust the sex of their offspring accordingly. It is therefore possible that a mother's biological condition (which is also connected with her reproductive potential), as measured by the neonatal weight of her first child, can be a good predictor of the second child's sex. From data for 227 healthy mothers from Wroclaw (Poland) we show that the probability of giving birth to a boy in the second pregnancy is higher after a relatively heavier first-born child (ANOVA, F(1,225)=3.79, P<0.053). This relationship, however, is only significant after a first-born daughter (F(1,117)=9.66, P<0.002) and not after a first-born boy. Some possible explanations of the fact that only the birth-weight of a first-born daughter--and not a son--can be a good predictor of the secondary sex ratio are also discussed.  相似文献
