IgA nephropathy is one of the most common glomerulonephritis in the world.Although the pathogenesis of IgA nephropathy is not clear yet, many studies have manifested that many factors such as environmental factors,genetic factors,and aberrantly glycosylated IgAlare involved in its pathogenesis. Currently, most studies focus on aberrantly glycosylated IgAl, lgA 1 circulating immune complexes depositing and abnormal IgAl removing.In addition, studies have found that ACE gene polymorphism especially DD genotype may be associated with the pathogenesis of IgA nephropathy.Furthermore, T lymphocytes, B lymphocytes,dendritic cells, transforming growth factor β1 and so on play an important role in the pathogenesis of lgA nephropathy.

Septic encephalopathy( SE) is defined as diffuse brain dysfunction that related to systemic inflammatory response and without clinical or laboratory evidence of central nervous system infection.SE is one of the most common complications of patients with severe sepsis.Its pathogenesis is very complex and is not yet clear.The clinical manifestations of SE varied and have no specificity, mainly for changes of con-sciousness and mental status.The performance of electroencephalography is more sensitive,and is associated with prognosis.Somatosensory evoked potentials could display the damage of cortical or subcortical path-ways.Brain MRI has a more accurate assessment of the nature and the extent of brain damage.SE is a diag-nosis of exclusion.Before the diagnosis of SE,we need to exclude other encephalitis and encephalopathy.The morbidity and mortality of SE are high.It requires close attention,early detection and timely treatment.

Dipeptydil-peptidase-4 (DPP-4) inhibitors are designed as oral anti-hyperglycemic drugs for the treatment of type 2 diabetes owing to their effects on the incretin system through sparing incretin hormones including glucagon-like peptide-1 (GLP-1) from rapid degradation by DPP-4.It has been shown that GLP-1 signaling may exert beneficial effects on cardiovascular system.In addition to GLP-1,DPP-4 physiologically cleaves cytokines,chemokines,and neuropeptides involved in inflammation,immunity,and vascular function.It means that DPP-4 inhibitors hold promise for cardiovascular protection independent of GLP-1.And its modulation of endothelial progenitor cells,infiammatory pathway,ischemic response,and lipid metabolism emerges as the major cardiovascular target of DPP-4 inhibitors.

Although small molecule drugs (SMD) are still mainstream for the treatment of diseases, large molecule biologicss of many advantages, pose a challenge to the further discovery and use of SMD. The advantages of SMD are the convenience of oral administration and good patient compliance. However, the challenge with SMD is to integrate the PD, PK, selectivity and safety into a chemical structure. Because of their small size and surface area they often bind to various proteins, and off-target actions can cause adverse reactions. In this sense, selectivity is critical. Based upon target as the core to construct a chemical structure, it is necessary to consider the requirements of all the attributes, but achievement of the full-dimensional optimization is difficult. Modern drug discovery has been greatly enhanced by molecular biology and structural biology, and new strategies and technologies have emerged, which have created many successful medicines. For example, under the guidance of structural biology, covalent binding drugs connect moderate "electrophilic warheads" to the appropriate positions of molecules, and upon binding to their targets the electrophiles are irreversibly linked to the target by covalent bonds. Molecular biology can be directly applied to the development of antibody-coupled drugs (ADC). The antibody (A) acts as a carrier and a guide (for PK), and carries toxic molecules (D) into cancer cells, thus playing a killing role (for PD). The separate pharmacodynamic and pharmacokinetic entities are coupled (C) by linkers. PROTACs are also bifunctional molecules, which recruit a target protein and ubiquitin ligase E3 to form a ternary complex, which then acts as a catalyst to ubiquitinate the target protein and lead to degradation by the proteasome. In addition, in recent years, the combination of two fixed-dose drugs has improved selectivity, safety, and long-term benefit with many severe diseases, and can be regarded as an innovative strategy of physical combination. This review discusses some successful examples to briefly present the principles from the perspective of medicinal chemistry and therapeutic application.

Primary open angle glaucoma ( POAG) is one of the eye diseases which can lead to blindness. The early symptom of POAG is unconspicuous, however, it will result in irreversible optic never damage and visual field defect with the disease progress. As an index for diagnosing and evaluating the therapeutic effect of POAG, intraocular pressure ( IOP ) is simple and important. Clinically, although some treated patients have a target IOP at clinic time, the optic never damage still get worse. Researches indicate that higher nocturnal IOP and 24h IOP variation and lower nocturnal ocular perfusion pressure ( OPP) may be the reasons for this phenomenon. The following essay will give an overview of POAG,IOP and OPP according to the relevant literatures so that we can have a better understanding.

ObjectiveTo observe the curative effect of sensory integration training on children with attention deficit hyperactivity disorder (ADHD).Methods60 ADHD children were randomly divided into trial group and control group with 30 cases in each group. Children in trial group were treated with sensory integration training besides routine medication, and assessed with Scale for Assessment of Attention Sensory Integration after treatment.ResultsAfter treatment, scores of large muscle dis-equilibrium and ill-proprioception increased obviously (P<0.01) ; scores of improper tactile defense and insufficient development of learning ability also increased (P<0.05) compared with pretreatment. The curative effect of trial group was better than that of control group (P<0.05 ).ConclusionOn the basis of medication, sensory integration training can improve the rehabilitation effect of ADHD children.
