The higher frequency of varicocele in men with infertility has drawn attention and resulted in increased research at the molecular level towards treatments. The aim of this study was to investigate the role of tumor necrosis factor （TNF）-related apoptosis-inducing ligand （TRAIL） and its receptors in varicocele-induced testicular dysfunction in an experimental rat model. The rats were divided into three groups： control, sham and varicocele. Varicoceles in rats were induced by partial ligation of the left renal vein and left testes. The rats were analyzed 13 weeks after surgery. The degree of DNA fragmentation within cells in the testis was determined using terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling （TUNEL） assay. Tubule degeneration was evaluated using the Johnsen score. The expression of TRAIL and its receptors was detected by immunohistochemical and Western blotting techniques. The apoptotic index, Johnsen score and the expression of TRAIL and TRAIL receptors were examined. The data are presented as the mean-.＋s.d, and were analyzed using computer software. The KruskaI-Wallis and Dunn＇s multiple comparison tests were used in the statistical analyses. The germ cell apoptotic index was increased in rats with varicoceles when compared with the sham and control groups （P=0.0031）. The Johnsen score was significantly decreased in the varicocele group when compared with the sham and control groups （P〈O.O001）. Immunohistochemical and Western blotting analyses showed that after varicocele induction, the expression of TRAIL-R1 and TRAIL-R4 in germ cells was increased and the expression of TRAIL-R2 was decreased. There are no significant differences among the groups in terms of TRAIL and TRAIL-R3 receptor expression. The results of this study indicate that TRAIL and its receptors may have a potential role in the pathogenesis of varicocele-induced testicular dysfunction.

In 1872, George Huntington presented his essay “On Chorea” to the Meigs and Mason Academy of medicine and, in doing so, detailed a disease that would later bear his name. Huntington's disease(HD) is a genetic, neurodegenerative disease that manifests as the loss of motor control,cognitive impairment,and mood and psychiatric changes in paents.

Neuronal growth, extension, branching, and formation of neural networks are markedly influenced by the extracellular matrix—a complex network composed of proteins and carbohydrates secreted by cells. In addition to providing physical support for cells, the extracellular matrix also conveys critical mechanical stiffness cues. During the development of the nervous system, extracellular matrix stiffness plays a central role in guiding neuronal growth, particularly in the context of axonal extension, which is crucial for the formation of neural networks. In neural tissue engineering, manipulation of biomaterial stiffness is a promising strategy to provide a permissive environment for the repair and regeneration of injured nervous tissue. Recent research has fine-tuned synthetic biomaterials to fabricate scaffolds that closely replicate the stiffness profiles observed in the nervous system. In this review, we highlight the molecular mechanisms by which extracellular matrix stiffness regulates axonal growth and regeneration. We highlight the progress made in the development of stiffness-tunable biomaterials to emulate in vivo extracellular matrix environments, with an emphasis on their application in neural repair and regeneration, along with a discussion of the current limitations and future prospects. The exploration and optimization of the stiffness-tunable biomaterials has the potential to markedly advance the development of neural tissue engineering.

To assess the potential health risks of mixed rare earths Changle for human embryo, whether it crosses placenta membrane or placenta barrier should be determined. In order to arrive at the aim placenta tissue was observed after contamination with optical and electron microscope to show distribution and destiny of mixed rare earth Changle in placenta tissue. Meanwhile the amount of rare earths in serum of pregnant rat, amniotic fluid and extract of embryo tissue were measured by using Inductively Coupled Plasma Mass Spectrometer (ICP MS). The rats were administered to 0 3, 2, 5 and 20 mg·kg -1 mixed rare earths Changle every day, respectively by oral from the 6th to 18th day after pregnancy. The results show that many particles are found in syncytiotrophoblast around capillaries of placental villi in contaminated groups under light microscope, and there are more particles following increased dose. It also was observed that some dense bodies with the envelope in placenta membrane and to difference extent damages the mitochondria crista within syncytiotrophoblast cytoplasm in contaminated groups under transmission electron microscope (TEM). Results of ICP MS assay indicate that the level of Ce increases with contamination dose in the serum of pregnant rats, and the level of total rare earth element remarkably rises in amniotic fluid and serum of pregnant rats for 20 mg·kg -1 group as compared with the control without change for the other groups.
