New technologies and ideas are constantly emerging recently. With the arrival of the era of minimally invasive surgery, most of the colorectal cancer surgeries can be conducted through minimally invasive techniques. In this study, we discuss the status, characteristics, controversy, and consensus of minimally invasive techniques in colorectal cancer surgery.

Assistive Technology Act of the USA is a very important law for the persons with disability in USA. The background of the Assistive Technology Act of the USA was reviewed and the guarantee of laws for the disabilities was discussed in the paper. From which, some theory and practice for special education of China can be obtained, and some experience and enlightenment for setting up related laws in China also can be worked out.

Rapid Golgi preparations of golden hamster dorsal lateral geniculate nucleus (LGd)show three classes of neurons with different morphological characteristics. Class Ⅰ and class Ⅲ cells are distributed throughout the LGd.Class Ⅱ cells are found more common medially at mid-genieulate levels.Class Ⅰ cells are multipolar neurons with large cell body.The smooth primary dendrites branch extensively. Spine-like and small excrescences are found along distal dendrites.Class Ⅱ cells have medium size pear-like cell body.The distal dendrites are usually derived from one primary dentrite.Dense cluster of dentritic protrusions is usually found at branch points of the dendrites.Class Ⅲ cells have the smallest cell body and are paucidendritie but the dendrites have complex protrusions including pearl-like dendritic appendages.Class Ⅰ and class Ⅱ cells possess an axon but most of class Ⅲ cells are not found to have an axon. The connections between the LGd and visual cortex was investigated using the retrograde horseradish peroxidase(HRP)histochemical method.After injection of HRP into the visual cortex,Class Ⅰ and class Ⅱ neurons were labelled but class Ⅲ celts were not suggesting that class Ⅰ and class Ⅱ cells are projecting neurons.Class Ⅲ cells do not seem to project to the visual cortex and are probably local circuit neurons.

Job Accommodation of American is effective to ensure the equal employment of domestic disabilities. This paper introduced its legal basis, contents and procedures.

This study revealed that the content of intra and extracellular polysaccharides may be related to the cultural conditions.With decreasing NaHCO 3 or NaNO 3 concentration,the content of intracellular polysaccharide was reduced,Reduction of NaNO 3 concentration still caused the rise of extracellular polysaccharides.The K 2HPO 4 or NaCl concentration also had an effect on the production of both intracellular and extracellular polysaccharides.When PH value of media maintained at 8.0,there was the highest content of intra and extracellular polysaccharides.The same high content also occurred after culture of nine days.In addition the content of intracellular polysaccharide was higher under continuous light than under the light/dark circle.

This paper reports serum ?_2 microglobiln (?_2M in abbreviation) in 216 normal children of different ages. Urin ?_2M in 60 normal adults; and both in 50 cases of common glomerular disease in children were detected by RIA. The results showed that serum ?_2M is more accurate than BUN in judging the renal function. The elecating serum ?_2M is coincidence with the elevating of diastolic pressure of the sick children. The dynamic observation on delayed cases examination of serum ?_2M and urin ?_2M may be of help in monitoring the pathological changes in glomerular and tubule.

The medical order number of a blood transfusion is used as the matching number in the full range of clinical blood use. A cycle is built ranging from the application for to the implementation of a medical order for blood transfusion. Such measures as repeated blood types verification by two departments, dual-database management of blood type files, and bar coding are called into play to ensure information correctness. These measures can make sure that the correct blood type is transfused to the correct patient and rule out accidents in blood transfusion. Indications for blood products are set up under real-time surveillance, which makes available limited blood products supply to those in need and minimizes waste and abuse of such products. The full-range and real-time management of clinical blood use will confine blood transfusion indications and ensure patients' safety with 100% match ratio.

Objective To study the expressions of matrix metalloproteinase-3 (MMP-3) and osteopontin (OPN) in cervical carcinoma and their relationship with invasion and metastasis. Methods The expression of MMP-3 and OPN were detected in 54 cases of cervical cancer tissues by immunohistochemical SP method. Compared with 15 cases of normal cervical tissues, the relationship was analyzed between both protein expressions and clinical pathology. Results The expression positive rates of MMP-3 and OPN in cervical cancer tissues (70.37 % and 66.7 %, respectively) were significantly higher than those of normal cervical tissues (20 % and 0, respectively), were significantly higher with infiltration depth >1/2 and lymph node metastasis than those with depth≤1/2 and without metastasis , respectively(P <0.05). The expressions of MMP-3 and OPN were related with depth of cervical infiltration and lymph node metastasis of cervical cancer.Expressions between MMP-3 and OPN were significantly positively correlation(r =0.401, P<0.05). Conclusion The expressions of MMP-3 and OPN are correlated with invasion and metastasis of cervical carcinoma.

ObjectiveThis paper discusses the instructional design of ＂General survey of medical culture＂,to provide the basis for the implementation of the teaching.MethodsThe first round of our teaching situation was concluded,to improve the teaching objectives,content,methods and the content and methods of teaching evaluation.Results The course is a new medical humanities curriculum to improve medical knowledge of the human spirit of nursing students,training the cultural literacy,but the teaching content should be combined with professional features,and teaching evaluation methods should be improved.ConclusionsRigorous designed curriculum,flexible and diverse teaching methods and forms of assessment and suggestions from the students are conducive to the improvement of the course.
