    Cholesterol sulfate (CS), synthesized by sulfotransferase (SULT) 2B1b, is an important steroid sulfate and plays important physiological roles in the human body. It is widely distributed in human body, such as skin, adrenal gland, liver, lung, brain and endometrium. CS participates in the formation of cornified envelopes and the expression of keratinocyte differentiation markers in the epidermis, thereby regulating epidermal desquamation and barrier function. CS inhibits T cell signaling during thymocyte development in the immune system, and CS/ Cholesterol ratio directly affects thymic selection for T cells, thereby participating in the shaping of T cell receptor repertoire. CS regulates brain metabolism and exerts neuroprotective effects by reducing oxidative stress, maintaining mitochondrial membrane stability and increasing energy reserves. In addition, CS also contributes to the development of many diseases by regulating the activity of functional proteins. The deletion and mutation of steroid sulfatase (STS) gene, which catalyzes the desulfurization of CS, directly leads to the occurrence of X-linked ichthyosis. CS is involved in the development of Alzheimer's disease by promoting the aggregation of amyloid β - protein (Aβ). CS regulates gluconeogenesis by inhibiting the activation of hepatocyte nuclear factor 4α (HNF4α). Thus CS is expected to treat type 2 diabetes. CS has abnormal expression in a variety of cancers, and can interact with matrix metalloproteinase-7 (MMP-7) to induce the aggregation and metastasis of cancer cells. The main challenges and research priorities at this stage are to reveal specific molecular mechanisms under different physiological and pathological conditions and to design feasible clinical treatments.

    Obsessive-compulsive disorder is a high disabling psychiatric disease, with unknown etiology. Many studies have shown that the pathogenesis of obsessive-compulsive disorder is associated with both genes and the environment. Epigenetics has provided an approach to explaining the influence on individual inheritance caused by environmental factors. Nowadays, several types of research have proved that there are differences in DNA methylation between obsessive-compulsive disorder patients and healthy population, and the DNA methylation may be strongly related to treatment response. Additionally, an increased level of microRNA was found in patients with obsessive-compulsive disorder. This review summaries the studies of epigenetics of obsessive-compulsive disorder and concludes the possible changes in epigenetic modifications to further understand the pathophysiology of obsessive-compulsive disorder.

    Acute-on-chronic liver failure (ACLF), caused by various factors, is a rapid decompensation of liver function based on chronic liver disease, which is often accompanied by multiple organ failure and high short-term mortality. So far, there is no effective treatment except liver transplantation, which is the only possible cure. The evaluation before surgery is critical. Due to the large amount of hepatitis B virus (HBV) patients in our country, the evaluation of HBV-related ACLF (HBV-ACLF) is important. Systems like COSSH-ACLF, and CLIF-ACLF could be used for the evaluation. For the timing of surgery, transplantation at the state of ACLF-2 may have more benefit for patients but the conclusion need more research to prove. During the perioperative period, management of organ failure and basic disease is needed. The timing of dissociation of the receptor and trimming of the donor need to be carefully managed during the surgery. After the surgery, beside the usual complication of liver transplantation, events such as infection, organ failure, hepatic encephalopathy should be dealt with. The condition of organ failures before and after liver transplantation is associated with the long-term mortality of patients.This article aims to make review on the assessment before liver transplantation, timing of transplantation, perioperative management, notice during surgery and complication after surgery based on massive clinical experience and plenty of document readings.

    The main symptom of a female pediatric patient was severely short stature. Ultrasound examinations during pregnancy showed that the limbs were short. The patient was characterized by sparse, fine, and silky hair and prenatal onset of disproportionate short-limb short stature. Radiographic findings showed metaphyseal dysplasia with epiphyseal in terminal femur and proximal tibia. Whole exon sequencing of DNA from peripheral blood was negative. However, sanger sequencing confirmed that the patient had carried g.181G→A/g.255C→T compound heterozygous variants of RNA component of mitochondrial RNA processing endoribonuclease (RMRP) gene, which is a non-coding RNA in human genome. The g.255C→T was a novel mutation. The clinical manifestations of cartilage-hair hypoplasia (CHH) are complex and typical symptoms can help diagnose the disease. CHH should be considered as a differential disease when whole exon sequencing was negative in patients with suspected bone disease. Sanger sequencing test can help confirm the diagnosis, contributing to evaluating the prognosis and prenatal diagnosis. Discovery of the novel variants has enriched the variant spectrum of CHH.

    Skin is the largest organ of human body. Its histological changes may reflect local lesions and serve as the manifestation of systemic diseases. Some molecules in the skin can absorb exciting light of a specific wavelength and emit emission light with a longer wavelength. These molecules are called endogenous fluorophores, and the emission light is called skin autofluorescence (SAF). Different endogenous fluorophore has its specific fluorescence spectrum. When the skin undergoes pathological changes, the content of certain endogenous fluorophores in the skin will change, and even new endogenous fluorophores will be produced. SAF detection technique is a non-invasive, convenient and low-cost optical measurement without toxic side effects, which contains autofluorescence imaging and autofluorescence spectroscopy. It plays a vital and distinctive role in the diagnosis and differential diagnosis of various skin diseases and evaluation of skin pathological changes by analyzing the fluorescence intensity and the excitation or emission spectrum of skin endogenous fluorophores, especially in the early diagnosis of the disease and long-term follow-up after treatment. So far, SAF technology has been used in differential diagnosis of psoriasis, atopic dermatitis, contact dermatitis and other types of inflammatory dermatosis, in monitoring the treatment effect, quantitatively evaluating skin wound healing and scar fibrosis and predicting the type of scar formation, in quantifying and calibrating skin aging and photoaging, in differential diagnosis of multiple types of benign or malignant skin tumors, in guidance of the scope of resection in surgical operations, etc. In addition, SAF produced by advanced glycation end products can also be used as one of the risk grading indicators for various system diseases such as endocrine system, nervous system, cardiovascular system, and urinary system. This article briefly introduces the principle of SAF detection techique, reviews the application of SAF technology to the diagnosis of diseases, supplements the application of other systemic diseases and provides an outlook on the future development of SAF detection technique, in order to provide reference for related medical fields.

Further exploration of the mechanism of anhedonia and clear definition and illustration of its pathophysiological basis are helpful to the diagnosis and treatment of related diseases. In recent years, converging evidence has implicated that inflammation-driven alterations in kynurenine pathway (KP) and tetrahydrobiopterin (BH4) metabolism lead to nerve injury and disturbance of neurotransmitter in reward circuit, which is closely related to the emergence and development of anhedonia. Therefore, this review aims to summarize the research advances in the inflammatory mechanism of anhedonia, with the emphasis on both KP and BH4 metabolism.

    Baicalin is one of the flavonoids extracted from the root of Chinese herb Scutellariabaicalensis, which is proved to be an effective component in fields of anti-oxidant, anti-inflammation and anti-virus. Based on further studies, baicalin is gradually known to have anti-tumor function. It has an impact on tumor via multiple mechanisms such as induction of tumor cell cycle arrest, induction of apoptosis of tumor cell, inhibition of tumor metastasis and regulation of tumor microenvironment, ranking it a hotspot in Chinese medicine of anti-tumor therapy. This article comprehensively reviews the previous studies on the anti-tumor effect of baicalin, in order to promote understanding of its anti-tumor mechanisms and provide a new insight in anti-tumor therapy.
