Cell culture technology is the most commonly used method in the in vitro experiments at present. However, monolayer cell culture technology has been unable to meet the demand of the researchers. This is because that monolayer cell culture cannot mimic the cellular environment in which multiple cells interact with each other in the body. We cannot discuss the relationship of many cells, because we do not know the relationship between cells through a single kind of cell. So cell co-culture medicine arises at the historic moment for the demand. With the development of research method in recent years, cell co-culture method also has been improved in practice: from direct contact co-cultures to indirect contact co-cultures, from two-dimensional co-cultures to three-dimensional co-cultures. Cell co-culture method is closer to the human body. It is also more advantageous to study the interaction among cells. Nowadays, there are more researchers tend to select this method to study the physiological and pathological in vitro model, tissue engineering, and cell differentiation research. At the same time, it has become the focus of drug research and development, drug analysis, mechanism of drug action, and drug targets. This article will review the studies of cell co-culture method, summarize advantages and disadvantages of various methods, so as to promote improvement of cell culture methods, to build cells co-culture system that more close to human body, and build the in vitro model that simulate internal circulation of human body further.

Objective To investigate the effect of electromyographic biofeedback motion sensing game on upper limb function in chil-dren with obstetric brachial plexus palsy (OBPP). Methods From March, 2013 to February, 2014, 41 children with OBPP were randomly as-signed into conventional rehabilitation group (n=21) and motion sensing game group (n=20). Both groups underwent a comprehensive course of rehabilitation, and the motion sensing game group received upper limb occupational therapy in the motion sensing game, for four weeks. They were assessed with Mallet shoulder function scale and the surface electromyogram (EMG) of the deltoid muscle when abduct-ing the shoulder before and after treatment. Results Before treatment, there was no significant difference in the Mallet scores between two groups (t=0.730, P>0.05), the scores improved after treatment in both groups (t>5.085, P<0.05), and the scores after treatment and the D-val-ue scores before and after treatment were higher in the motion sensing game group than in the conventional rehabilitation group (t>3.195, P<0.01). The integral EMG (iEMG) value, average EMG (aEMG) value and maximum EMG (EMGmax) value of the deltoid muscle improved in the motion sensing game group after treatment (t>4.420, P<0.05), however, only aEMG and iEMG improved in the conventional rehabili-tation group (t>2.282, P<0.05). All of them after treatment and the D-value were higher in the motion sensing game group than in the con-ventional rehabilitation group (t>2.155, P<0.05). Conclusion Electromyographic biofeedback motion sensing game therapy plays a role in the rehabilitation of upper limb function and muscle strength in children with OBPP.
