Correlation Analysis Between Ovarian Reserve and Thyroid Hormone Levels in Infertile Women of Reproductive Age.

Objective: To analyze the correlation between ovarian reserve and thyroid function in women with infertility.

Methods: Retrospective analysis of the data of 496 infertility patients who visited the clinic between January 2019 and December 2020. According to the TSH level, it is grouped into <2.

The Analysis of Anxiety and Depression in Different Stages of in vitro Fertilization-Embryo Transfer in Couples in China.

Background: This study aimed to examine the differences in anxiety and depression between infertile Chinese couples in diverse stages of in vitro fertilization-embryo transfer (IVF-ET) and their relationship with the IVF-ET outcomes.

Methods: From February 2016 to December 2018, a total of 247 couples that were undergoing IVF-ET were randomly selected for this study. On the day they started their treatment (T1), the day human chorionic gonadotropin was administered (T2), and 4 days after the embryo transfer (T3), self-designed questionnaires, the Self-Rating Anxiety Scale, and the Self-Rating Depression Scale were completed to investigate anxiety and depression in different stages.

The relationship between the hormone levels before transplantation and the outcomes of hormone replacement therapy frozen embryo transfer.

Background: The aim of the present study was to analyze the relationship between the outcomes of hormone replacement therapy frozen embryo transfer (HRT-FET) and serum estradiol and progesterone levels on the day of endometrial transformation and before transplantation.

Methods: Clinical data of patients who underwent 426 cycles of HRT-FET were retrospectively analyzed and were divided into group according to estradiol and progesterone levels. Differences in embryo implantation rate and clinical pregnancy rate were compared, and relationship between estradiol levels and outcome of transplantation was analyzed.

Highly efficient release of lovastatin from poly(lactic-co-glycolic acid) nanoparticles enhances bone repair in rats.

Lovastatin exhibits higher thermal stability and lower degradation rate than simvastatin. However, the amount of research studying a lovastatin delivery device has been far less than similar research on simvastatin. As a consequence, a high lovastatin release rate system has not been developed.

[Identification and clonogenicity of side-population cells in human decidua of first trimester pregnancy].

Objective: To explore the existence of side-population cells (SP cells) in human decidual tissues in early pregnancy, and its biological characteristics.

Methods: Decidual cells were obtained by enzymatic digestion from the decidual tissues of human early pregnancy. The cells then were stained with Hoechst33342 dye either alone or in combination with verapamil.

[Analysis of sulfur compounds in residue fluid catalytic cracking gasoline].

Sulfur compounds in residue fluid catalytic cracking (RFCC) gasolines from Refinery of SINOPEC Beijing Yanshan Company and Refinery of Shijiazhuang were analyzed by gas chromatograph connected with flame photometric detector (FPD) and atomic emission detector (AED). Twelve and 26 kinds of sulfur compounds were detected by AED in RFCC gasolines from Yanshan and Shijiazhuang respectively. Only 0 and 19 kinds of sulfur compounds were found by FPD in these two gasolines respectively.
