ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of delayed skin grafting combined traction in severe joint cicatricial contracture.</p><p><b>METHODS</b>At the first stage, the joint cicatricial contracture was released completely with protection of vessels, nerves and tendons. The wound was covered with allogenetic skin or biomaterials. After skin traction for 7-14 days, the joint could reach the extension position. Then the skin graft was performed on the wound. 25 cases were treated from Mar. 2000 to May. 2013.</p><p><b>RESULTS</b>Primary healing was achieved at the second stage in all the cases. The skin graft had a satisfactory color and elasticity. Joint function was normal. All the patients were followed up for 3 months to 11 years with no hypertrophic scar and contraction relapse, except for one case who didn' t have enough active exercise on shoulder joint.</p><p><b>CONCLUSION</b>Delayed skin grafting combined traction can effectively increase the skin graft survival rate and improve the joint function recovery.</p>

objective:To investigate the cause,pathogenesis,diagnosis and treatment of Wernicke encephalopathy(WE) after total parenteral nutrition(TPN). Methods:A retro spective study was conducted on 20 cases of clinical data about WE after long period of TPN. Results:WE usually occurred in the 2th～3th week of TPN support.18 cases of WE were treated with vitamin B_(1) in time,their symptoms disappeared and survived.2 patients died with misdiagnosis. Conclusion:Vitamin B_(1) is the key point to prevent and treat WE after long period of TPN.
ABSTRACT
Objective To evaluate the possibility of detection mutations of multiple genes in stool for secondary screening for colorectal cancer.Methods Tumor specimens and stool samples from 40 patients with colorectal cancer and 40 normal persons were examined for mutations of p53,K-ras and APC gene by polymerase chain reaction single strand conformation polymorphism(PCR-SSCP) and silver nitrate staining.Results ①The mutation rate of p53,K-ras and APC gene in the tissues and stools of colorectal cancer respectively were 57.50%,50.00%,60.00% and 42.86%,40.00%,51.43%,and no mutations were found in normal mucosa and stool.②The mutation ratioes between multiple gene and single gene had significant difference(P
