Amyotrophic lateral sclerosis(ALS)is a progressive neurodegenerative disorder.Mutations in the Cu,Zn-superoxide dismutase(SOD1)gene cause ALS by an unknown gain-of-function mechanism.Current researches show that diminishing SOD1 mutation enzymatic activity does not account for motor neuron lose in ALS,while direct toxicity of variant SOD1 protein or aggregation of SOD1 protein may impart cell function and cause motor neuron death.Though motor neuron death is selective,other cells also participate in this course.The author reviewed recent advances in the relationship between mutant SOD1 and Amyotrophic Lateral Sclerosis.

Chimeric antigen receptor natural killer cell (CAR-NK) is a new promising immunotherapy. NK cell can derive from peripheral blood cells, cord blood cells, NK-92 cell line and iPSC cells. CAR-NK cells can recognize target antigens non-specifically and are not restricted by human leukocyte antigens. Allogeneic infusion of CAR-NK cells does not cause graft-versus-host disease. It has a strong effect on primary cells of leukemia, lymphoma and multiple myeloma, thus making animal models have strong anti-tumor effect. Therefore, as a "off-the-shelf" product, CAR-NK cells have a wide range of clinical applications. In this paper, the construction of CAR-NK vector and its preliminary clinical application in hematological tumors and the challenges were reviewed.

[Objective]This paper aimed at discussing the application of pulse in the clinical through the analysis of medical cases by Wang Mengying. [Methods]Revisited the theory and practice of pulse in the medical cases of Wang Mengying and discussed Wang's experience in the clinical application of pulse in the diagnosis and treatment of diseases such as protration syndrome and cholera.[Results]The pulse is better than the other three in the diagnosis of patients with etiology and pathogenesis.Pulse can reflect the situation of patients ’etiology and pathogenesis.The process of disease can be plumbed through pulse diagnosis. [Conclusion] Ancient doctor attached great importance to the pulse,it can guide our clinical practice better through the study of pulse in modern clinical work.

[Abstrct] More and more laboratory indicators including serum creatinine , serum cystatin C , urinary microalbumin, N-acetyl-beta-D-Glucosaminidase (NAG), kidney injury molecule 1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), interleukin 18 (IL-18) and L type fatty acid binding protein (L-FABP) are used to diagnose and monitor acute kidney injury (AKI).However, the clinical applicability and limitations of these indicators , as well as the detection effect factors and biological variation on the diagnosis and monitoring of AKI are very important , especially how to combine the detection effect factors and biological variation to interpret test result is attached great importance by the laboratory personnel .

The paper expounds the practical significance of the humanistic quality of medical staff,and probes into the cultivation path according to the problems existing in the humanistic quality of medical staff,aimed at promoting the new health care reform orientation,in order to better practice the modern biological-psychological-social medical model,and to provide a useful reference for constructing harmonious doctor-patient relationship.

Objective To observe the effect of community rehabilitation on the motor function and activities of daily living(ADL)of stroke patients.Methods 155 stroke patients were randomly divided into the exercises group(n=76)and control group(n=79)and evaluated with simple Fugl-Meyer Assessment(FMA),Modified Barthel Index(MBI)and Functional Comprehensive Assessment(FCA)before treatment and 1 and 3 months after treatment.Results The evaluations of FMA,MBI and FCA were not different between two groups before treatment.One month later,the scores of MBI and FCA of the exercises group improved significantly(P<0.01),but simple FMA not improved even to 3 months after treatment(P>0.05).In the control group,the simple FMA score not improved(P>0.05),the scores of MBI and FCA had a declined tendency with disease course prolong.Conclusion The effect of community rehabilitation on the motor function of stroke patients during convalescence is not significant,but community rehabilitation may improve ADL and the quality of life.

BACKGROUND:Alginate-chitosan microcapsule can improve the mechanical property of sodium alginate hydrogels. How to obtain the ideal sodium alginate-chitosan microcapsule and the prospect for application of the microcapsule system is the key to this study.
OBJECTIVE:To investigate the preparation method and formation mechanism of alginate-chitosan microcapsules, to analyze several important factors affecting the strength of the microcapsule membrane, and to explore the prospects of alginate-chitosan microcapsules in immobilized celltechnology, in tissue engineering and as a drug carrier.
METHODS:The first author searched PubMed, Elsevier ScienceDirect, CNKI and Wanfang database (1987/2013) to retrieve literatures about the preparation method, formation mechanism and application prospect of alginate-chitosan microcapsules.
RESULTS AND CONCLUSION:Sodium alginate hydrogels have many advantages in drug release and tissue engineering, but its application is limited by gel dissolution phenomena and deficiencies in its mechanical properties. Chitosan-alginate microcapsules make up for the deficiency of sodium alginate hydrogels by electrostatic interactions to form polyelectrolyte complexes. By control ing the nature of the chitosan solution--the molecular weight of chitosan, pH and concentration of chitosan solution, we can prepare the microcapsules with high film strength. Alginate-chitosan microcapsules have shown broad application prospects in immobilization technology, drug release and tissue engineering.

The damage to the barrier of colonic mucosal epithelial cells is the fundamental cause of bacterial translocation.The tight junction among epithelial cells forms the most important constituent part of the mechanical barrier of the organism to prevent bacterial translocation from happening in the intestinal canal.The para-colonic-mucosal-epithelial-cell space is closed by protein complexes which are considered to be used for regulating the permeability between cells.ZO-1,Claudin-1 and Occludin are the most representative among the numerous protein complexes.They have become the important index to judge the damage degree of the barrier of colonic mucosal epithelial cells in test.The endotoxin is the product released by bacteria.Anti-endotoxin is one of the methods to protect the colonic mucosal barrier,to prevent and treat bacterial translocation.There are anti-endotoxin drugs.However,there has not been any drug widely recognized clinically up to now.Qingyi Decoction and Chaiqin Chengqi Decoction are the traditional Chinese medicine with the function of protecting the intestinal mucosal barrier and suppressing the transloeation of enteric bacteria.Oxymatrine has many pharmacological effects such as anti-bacterial,anti-inflammatory and immunoragulation.The recent animal experiments showed that oxymatrine has protective effect on the intestinal mucosa during severe infection.However,the mechanism of the drug action has not been completely known and needs to be studied in depth.Our traditional Chinese medicine applies extensively in clinical application of the prevention of the damage to the colonic mucosal epithelial cells during severe infection.

The term complication is defined as a secondary disease, an accident, or a negative reaction occurring during the course of an illness and usually aggravating the illness. It usually takes two forms: a secondary illness of a disease; or a complication resulting from medical treatments.Characteristic of being risky, predictable, uncertain, and relatively avoidable, complications are affected by a variety of factors. In the course of identifying medical malpractice, identification of complications should be achieved according to how complications occur and evolve in the entire course of treatment and care, whether staffs have followed standards and regulations for treatment and care, whether staff are well aware of their obligations to take precautions to avoid risks, and provide medical care once complications take place, whether malpractice exists in the practice of medical staff, whether a cause -effect relationship exists between complications in patients and harms caused to families and medical malpractice.
