Abstract： With the increasing rise in antidepressant consumption, more and more antidepressants and their metabolic products enter into water and soil environments. This will cause toxicity to animals living in these environments, and antidepressants may be transferred to humans via food chain, leading to human health risks. Based on national and international publications pertaining to environmental pollution and toxic effects of antidepressants during the period between 2005 and 2021, this review summarizes the biological accumulation, acute toxicity, reproductive and developmental toxicity, metabolic effects and biological behavior changes of antidepressants, so as to provide insights into the elucidation of the impact of antidepressants on human health risks.

Objective To analyze the value of multi-slice spiral CT (SCT) scan in staging and subtyping of renal cell carcinoma (RCC). Methods The preoperative kidney SCT data and postoperative pathology results of 64 patients with RCC were retrospectively analyzed. The patients′ ages ranged from 33-78 years (average 54 years). There were 44 males and 20 females in the study group. According to the CUA Guidelines, the staging and subtyping of RCC were performed through the combined information of preoperative SCT attenuation in unenhanced, corticomedullary phase and enhancement pattern. The results were compared with the postoperative histopathological results. Results The SCT results showed 38 cases were clear cell RCC, 14 cases were papillary RCC and 12 cases were chromophobic cell RCC. Histopathological results showed that 40 cases were clear cell RCC, 16 cases were papillary RCC and 8 cases were chromophobic cell RCC. According to the standard of 40 HU of CT attenuation value, the sensitivity, specificity and accuracy were 75%, 79% and 78% for diagnosis of papillary RCC in the unenhanced phase. The sensitivity, specificity and accuracy by the standard of 90 HU of CT attenuation value was 90%, 88% and 89% for diagnosis of clear cell RCC in the corticomedullary phase. In chromophobic RCC, homogeneous enhancement was more common than in papillary RCC and clear cell RCC. There was no significant difference of staging and subtyping of RCC between SCT and pathological results (P>0.05). The accuracy of SCT in staging and subtyping of RCC was 88% in staging, and 89% in subtyping. Conclusions SCT is a useful preoperative tool to stage and subtype RCC

Abstract Recent years have witnessed more attention paid to the health effects of the natural radionuclide 226Ra, and a series of research carried out on the detection methods of 226Ra at home and abroad. The common 226Ra detection methods are emanation scintillation, gamma spectrometry, liquid scintillation counting, alpha spectrometry and alpha counting. Emanation scintillation is mature enough as a classical method, while gamma spectrometry and liquid scintillation counting proceed fast. Due to the radiation of 226Ra, these detection methods still have the problems such as the requirement for large samples, long detection periods, complicated steps, high detection limits and low recovery rates. This paper reviews the five methods above and summarize their advantages and disadvantages, so as to provide the reference for selecting and optimizing the detection methods for different samples as well as perfecting the standard method in China.

Abstract Bisphenols (BPs), which are mainly used in the production of polycarbonates and epoxy resins, are common endocrine disruptors (EDCs) in natural environments. Human mainly exposes to BPs via ingestion and skin. Previous studies have deteted BPs in human urine, serum, and milk samples, and children and pregnant women have a high level of exposure to to BPs. Based on international and national publications pertaining to BPs since 2009, this review describes the exposure to BPs in human urine, serum, and milk and summarizes neuroendocrine dysfunctions, oxidative stress injury and epigenetics changes caused by BPs, so as to provide insights into reducing the exposure to and health risk of BPs.

Iodine is an essential nutrient required for thyroid hormone synthesis and human growth and development. Iodine requirements increase substantially during pregnancy, and insufficient iodine intake may affect the health of pregnant women, and fetal growth and development. Iodized salt-based iodine supplementation is effective to improve maternal iodine levels, reduce risk of thyroid dysfunctions, and plays a vital role in improvements of offspring growth and development and prevention of intellectual disability. However, excessive iodine supplementation during pregnancy may affect maternal thyroid functions and the nerve development of offspring. Precise and personalized iodine supplementation schemes are therefore required tailored to local iodine deficiency degree and pregnant women's individual iodine status. This review summarizes the advances in the impact of iodine supplementation during pregnancy on maternal and offspring health, so as to provide insights into the guidance of iodine supplementation during pregnancy.

Aim To investigate the effects of harpagide on cerebral ischemia and the mitochondria mediated Caspase dependent apoptotic signaling pathway in mice.Methods The MCAO was employed to establish MCAO model.When the models were established, the mice were given harpagide (4, 8, 12 mg·kg-1) and edaravone (3.2 mg·kg-1) [0.1 ml·(10 g)-1] by tail vein injection after MCAO immediately.And the model and control mice were given equivalent normal saline by the same way.After MCAO for 6 h, the behavior, volume of cerebral ischemia and pathological changes in the brain were observed.Westernblot was employed to determine the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Results Compared with the model group, harpagide (4, 8, 12 mg·kg-1) could significantly decrease the increased nerve functional score, brain index, brain water content and volume of cerebral ischemia induced by cerebral ischemia.Harpagide (4, 8, 12 mg·kg-1) could reduce the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Conclusion Harpagide may have protective effect on the cerebral ischemia injury in mice, which might be related to the inhibition of the cerebral mitochondria mediated Caspase dependent apoptotic signaling pathway.

Objective To investigate the effect of isoflurane inhalation during gestation period on plasticity of hippo-campal synapses in offspring rats. Methods Ten healthy pregnant SD rats at 14 day gestation were randomly divided into 2 gorups ( n = 5 each): control group (group C) and isoflurane group (group I). The rats in group C were mechanically ventilated with O2 while in group I the rats inhaled 1.3% isoflurane in O2 for 2 h a day until labor. Four weeks after birth 4 offspring rats from each pregnant rats (2 male, 2 female) were tested for learning and memory abilities using Morris water maze. Then the offspring rats were sacrificed and hippocampi isolated. The synaptic structure of hippocampal CA1 area was examined by trans-electron microscopy. Results Morris water maze test showed that the escape latency was significantly shorter and the number of times of spanning flat roof greater in group C than in group I. The structure of hippocampus was intact in group C but incomplete in group I. Meanwhile the thickness of synaptic density was significantly decreased in group I. Conclusion Isoflurane anesthesia of pregnant rats may induce learning and memory disabilities in offspring rats by inhibiting the plasticity of synaptic structure in hippocampus.
