Objective This report describes the mechanism of Ginsenoside Re to resist Exercise-induced fatigue based on the observation of effects on MDA content and SOD activity.Methods Thirty male SD rats were divided into 3 groups randomly:Ginsenoside Re group,model group and control group,10 rats in each group.Rats in Ginsenoside Re group were given gastric gavage of Ginsenoside Re once a day,while rats in model and control groups were given the same volume of normal saline.One hour after administration,rats of Ginsenoside Re groups and Model groups received medium-intensity treadmill exercise for 20 minutes at the speed of 15m/min,with a slope of 0 degree,and after 40-mimute break repeated it for another 20minutes.Fourteen days later,MDA content and SOD activity have been tested.Results MDA content in the serum,liver tissue and muscle tissue of Ginsenoside Re group was obviously lower than that in the model group (P

Objective To investigate the association of HIF-1αand VEGF signaling in missed abortion. Methods Fifty patients with missed abortion were selected as study group, and fifty early pregnant women who underwent artificial abortion surgery were selected as control group. The expressions of HIF-1α and VEGF were measured by immunohis-tochemistry. Results The expressive rate of VEGF was 100%in the control group and 66% in the study group. The ex-pressive rate of HIF-1α was 42% in the control group and 76% in the study group. Compared with the control group, the expression of VEGF was statistically reduced(P<0.05) while the level of HIF-1α was significantly up-regulated(P<0.05)in the study group. In the control group, HIF-1αwas positively correlated with VEGF(r=0.387,P<0.05), while in the study group HIF-1α was close negatively correlated with VEGF(r=-0.298,P>0.05). Conclusion The decrease of VEGF and increase of HIF-1αin villous trophoblastic cells may be signals of occurrence of missed abortion.

Objective:
Cognition impairments are considered as a fundamental characteristic of severe mental disorders (SMD). Recent studies suggest that hyperprolactinemia may exert a detrimental influence on cognitive performance in patients with SMD. The objective of this study was to investigate the correlation between serum prolactin levels and cognitive function in female individuals diagnosed with SMD.
Methods:
We conducted a study on 294 patients with SMD and 195 healthy controls, aged between 14 to 55 years old. Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), while prolactin levels were measured in serum. Descriptive analysis and comparative analysis were performed to compare cognitive function and prolactin levels between groups, and linear regression models were used to explore the relationship between prolactin and cognitive function.
Results:
Compared to the healthy control, individuals with SMD exhibited significantly higher levels of prolactin, while scoring lower on RBANS total and every index scores. Furthermore, a negative association between prolactin levels and cognitive function (RBANS total index score, attention, and delayed memory) was observed in SMD patients. Importantly, this inverse correlation between prolactin and cognition function (RBANS total index score, total scale score, and attention) persisted in patients who were not taking medications that could potentially influence serum prolactin levels.
Conclusion
Our study reveals a significant correlation between elevated prolactin levels and cognitive impairment in female patients with SMD, underscoring the importance of monitoring prolactin levels in order to prevent cognitive deterioration among female SMD patients.

ABSTRACT
Currently, there is a limited range of specialized oral preparations available for children, and it is common to find adult medications being used for pediatric purposes. This indicates a need for the development of new formulations specifically designed for children. Microparticle coating technology shows promise in masking the unpleasant taste of drugs, improving compliance and convenience in administration. Therefore, it can be considered an ideal approach for developing pediatric preparations. This article summarizes the current research and application status and development prospects of children's micro powder coating technology, providing reference for the application of micro powder coating technology in the field of children's oral preparations.
