Long non-coding RNA (lncRNA) is a class of RNA molecules, transcripted by RNA polymeraseⅡ, which consists of more than 200 nucleotides and protein-coding function. Many studies have indicated that lncRNA plays an important role in epigenetics, transcription and post-translational processing. The abnormal expression of lncRNA significantly correlates with occurence,development, and metastasis of renal cell carcinoma (RCC) and prognosis of the patients with RCC. This paper summarizes the advances in the research on lncRNA in RCC to reveal the mechanisms of the disease at the molecular level, in order to provide new methods of prevention, diagnosis, treatment and prognostic assessment of RCC.

Steroid-induced necrosis of the femoral head (SNOFH) is a common orthopedic disease,which is difficult to cure and has poor clinical prognosis. The number of SNOFH patients in China is still increasing year by year,which seriously threatens human health. Long-term non-standard or short-term extensive use of hormone (GC) is an important reason for the occurrence of this disease. At present,SNOFH is mostly treated by surgical methods such as hip replacement,which has limitations of great harm to patients and high cost. In recent years,with the continuous deepening and innovation of traditional Chinese medicine(TCM) research,the use of TCM to treat SNOFH has been widely used in clinical practice. The main TCM pathogenesis of SNOFH is kidney deficiency and blood stasis. Therefore,TCM monomer and compound compound of tonifying kidney and promoting blood circulation are used to treat SNOFH. And TCM has obvious therapeutic effect,small side effects,less cost and other advantages. Glycoprotein/beta chain protein secretion (Wnt/beta- catenin) signaling pathway as a classic signaling pathway is closely related to the bone,between its by promoting bone marrow mesenchymal stem cell update,enhance the activity of osteoblast and suppress the apoptosis,which adjust the metabolic balance of bone tissue,increase bone density,will play an important role in the process of bone formation. In recent years,the use of TCM monomers and compounds to regulate Wnt/β-catenin signaling pathway to accelerate bone marrow mesenchymal stem cells,promote their transformation into osteoblasts,and maintain bone metabolic balance mechanism to treat SNOFH has become a new research hotspot. This article reviews the research progress of TCM in the prevention and treatment of SNOFH by regulating Wnt/β-catenin signaling pathway,in order to provide reference for the application of TCM in the treatment of SNOFH.

Objective To determine the effects of treadmill training on the structure of hippocampal myelin and cognitive function in rats exposed to acute plateau hypoxia.Methods With 30 SPF-grade female SD rats (aged 6-8 weeks,weighing 200-220 g),6 of them were used for observation of myelin structure after injury,and the remaining 24 rats were randomly divided into control group,hypobaric hypoxia group and treadmill training group (n=8).The rats in above experimental groups were placed in a low-pressure oxygen chamber at an altitude of 6000 m for 7 consecutive days,and the rats of the control group were placed in the confined chamber for the same period without hypoxia.Then,the rats of the treadmill training group received a 4-week treadmill training scheme since the day after hypoxia.Finally,all the rats were tested for cognitive function with open field test (OFT)and Morris water maze (MWM).Transmission electron microscopy (TEM) was used to observe the changes of demyelination in the hippocampus. The expression of oligodendrocyte transcription factor 2 (Olig2)and myelin basic protein (MBP )in the hippocampal CA1 and CA3 regions was measured by immunofluorescence staining and Western blotting.Results Behavioral tests showed that the number into the central area,total distance,distance ratio in OFT and the number of platform crossings and distance to the target area in MWM were reduced in the hypobaric hypoxia group than the control group (P<0.05 ),while these indexes were increased in the treadmill training group than in the hypobaric hypoxia group (P<0.05).Immunofluorescence staining indicated that the number of Olig2 positive cells per unit area and the mean fluorescence intensity of MBP in the CA1 and CA3 regions were significantly lessen in the hypobaric hypoxia group than the control group (P<0.05 ),while these indicators were higher in the treadmill training group than the hypobaric hypoxia group (P<0.05 ).Western blotting displayed that the expression levels of Olig2 and MBP in the hippocampus were obviously lower in the hypobaric hypoxia group than the control group (P<0.01 ),while the levels were increased in the treadmill training group than the hypobaric hypoxia group (P<0.01 ).Conclusion Treadmill training promotes the number of the oligodendrocyte spectrum cells in CA1 and CA3 regions,enhances the expression of myelin-related proteins and improves myelin repair in hippocampus of hypobaric hypoxia rats,and thereby ameliorates hypoxia-induced anxiety-like behaviors and memory dysfunction.

Diabetic retinopathy (DR) is one of the most common chronic microvascular complications of diabetes mellitus. It has a high rate of blindness, and the age of onset is gradually getting younger, which seriously affects the physical and mental health and quality of life of patients. The disease is retinal damage induced by diabetes mellitus, which is a kind of fundus disease with the main manifestations of fundus hemorrhage, hard exudation, microhemangioma, cotton-wool spots, neovascularization, etc. In traditional Chinese medicine (TCM), it is classified into the category of "diabetic cataracts" and other diseases. At present, there is no effective method to prevent the progress of the disease in modern medicine, so it is particularly important to choose a reasonable and effective intervention to prevent and treat DR. Studies have confirmed that TCM has unique advantages in the treatment of DR. It can use its advantages of multiple bioactive components, multiple targets, and multiple pathways to intervene in the development process of DR from various aspects. By searching for the relevant literature on the progress of the intervention of DR with TCM monomers and compounds, this paper mainly reviews the relevant research results of the treatment of DR with multiple signaling pathways such as phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), nuclear factor kappa-B(NF-κB), p38 mitogen-activated protein kinase (p38 MAPK), nuclear factor erythroid 2-related factor (Nrf2)/hemeoxygenase-1 (HO-1), Hippo, advanced glycation end products (AGEs)/receptor for advanced glycation end products (RAGE), and Akt/glycogen synthase kinase-3β (GSK-3β), so as to provide more ideas and directions for the clinical prevention and treatment of DR.

Osteoporosis (OP) is a systemic metabolic disease that affects the health of middle-aged and elderly people by crosslinking multiple signaling pathways. With the increasing aging of the population, the incidence of OP is also increasing year by year. Because of a series of problems such as high incidence, difficulty in treatment, and poor prognosis, it has been widely studied and reported by scholars in China and abroad. At present, the drugs used by western medicine are mainly divided into two categories: Bone resorption inhibitors and bone formation promoters. Although the efficacy is reliable, there are still deficiencies such as poor dependence of patients on the drug, uncontrollable side effects, and high costs. However, in recent years, with the continuous deepening and innovation of traditional Chinese medicine (TCM) research, the treatment of OP by TCM has been widely recognized in clinical practice. Many scholars have found that the mechanism of TCM in the treatment of OP includes the widespread involvement of mitogen-activated protein kinase (MAPK) signaling pathway, which mainly promotes the differentiation of bone marrow mesenchymal stem cells (BMSCs) to osteoblasts (OB), inhibits the differentiation of osteoclasts (OC), and improves the expression of osteogenesis-related factors alkaline phosphatase (ALP), Runt-associated transcription factor 2 (Runx2), type Ⅰ collagen (ColⅠ) to treat OP. Although the current research on the TCM treatment of OP through the MAPK pathway is deepening, there are still certain deficiencies in the study of its molecular mechanism. Therefore, this paper reviewed the relationship between the MAPK signaling pathway and key target protein factors and OP to clarify the important role of the MAPK signaling pathway in OP. At the same time, the targeted regulation of MAPK signaling pathways by TCM to treat OP was systematically summarized in order to provide a scientific basis for the further accurate treatment of OP in TCM.

Vesicular glutamate transporter 2(VGlut2)is expressed in the PVN of the hypothalamic paraventricular nucleus(PVNVG1ut2)as an excitatory neurotransmitter,which regulates food intake and energy metabolism and plays an important role in maintaining homeostasis.However,it is not clear that the upstream and downstream projection network of PVNVGut2 neurons hinders the anal-ysis of glutamatergic neuron circuit function.Anterograde and retrograde tracer viruses were injec-ted into the PVN of VGlut2 mice by stereotactic brain injection technique to find the input and output nuclei of PVNVGlut2 neurons.Anterograde tracing results showed that PVNVGlut2 neurons pro-jected to the downstream medial amygdala(MeAD)and arcuate nucleus(ARC).Retrograde trac-ing results showed that PVNVGlut2 received input from the prefrontal nucleus(Pr),the reticular tegmental nucleus(RtTg),and the hypoglossal nucleus(12N).In addition,VGlut2 was found to be co-expressed with neuronal nitric oxide synthase(nNOS)neurons in the PVN.The anatomical net-work of PVNVG1ut2 neurons was analyzed by virus tracking tool,which laid the anatomical founda-tion for further study on the functional regulation of PVNVGlut2.

As a threat to human health, steroid-induced osteonecrosis of femur head is a common refractory orthopedic disease mainly caused by glucocorticoids, with poor prognosis and unclear pathogenesis. Osteogenesis-associated signaling pathways play an important role in bone formation. Glucocorticoid-induced abnormal activation and transport of these signaling pathways lead to abnormal differentiation of bone marrow mesenchymal stem cells, dysfunction of bone metabolism, and osteogenesis disorders, which may be the main reasons for the occurrence and development of steroid-induced osteonecrosis of femur head. Bone formation and remodeling need the participation of bone marrow mesenchymal stem cells, which are stem cells characterized by continuous self-renewal and differentiation. The key to strengthening bone remodeling is to improve the osteogenic differentiation capacity, which is the key point to inhibit bone resorption and prevent bone marrow mesenchymal stem cells from differentiating into osteoclasts. Traditional Chinese medicine (TCM) has been used in the treatment of osteonecrosis in ancient times. It is recorded in the Treasury of Words on Materia Medica (《本草汇编》) that "The deficiency in the lower energizer cannot be tonified without Eucommiae Cortexz.The soreness in lower legs cannot be alleviated without Eucommiae Cortex...The pain in the waist and knee cannot be relieved without Eucommiae Cortex...Tonifying liver and invigorating kidney, Eucommiae Cortex is an essential medicine." This indicates that ancient physicians have already begun to use the liver-tonifying, kidney-invigorating, and sinew-bone-strengthening effects of Eucommiae Cortex for the treatment of osteonecrosis. As the national support for the development of TCM strengthens, increasing studies have been conducted on the TCM prevention and treatment of steroid-induced osteonecrosis of femur head. Studies have suggested that Chinese medicinal herbs can exert a positive effect on the differentiation of bone marrow mesenchymal stem cells by affecting targeted signaling molecules, and promote osteogenesis and bone defect repair, thus combating the occurrence and development of steroid-induced osteonecrosis of femur head. The regulation of osteogenic signaling pathway by Chinese medicines to prevent steroid-induced osteonecrosis of femoral head has become a hot research topic. This article reviews the studies about the prevention and treatment of steroid-induced osteonecrosis of femur head with the active components in Chinese medicinal herbs by regulating osteogenic signaling pathways. We then explore the mechanism of the active components in promoting the differentiation of bone marrow mesenchymal stem cells into osteoblasts and inhibiting their differentiation into osteoclasts to facilitate bone formation, aiming to provide a reference for the further study of treating steroid-induced osteonecrosis of femoral head with Chinese medicinal herbs.
