Survivin variants specific real time quantitative RT-PCR was developed to analyze their expression in 53 paired cancer and para-cancerous tissues, and the expression of the wild-type survivin protein was detected by immunohistochemistry. The results showed that survivin mRNA and protein were expressed in gastric cancer and para-cancerous tissues. The survivin-2B was dominantly expressed in para-cancerous tissues, whereas the survivin-DeltaEx3 was more frequently detected in cancer tissues. The positive rate of survivin-2a was 100% in both cancer and para-cancerous tissues, but its relative transcript expression level was not significantly increased in cancer tissues in comparison with para-cancerous tissues. The correlation analysis revealed that the expression of survivin-2a mRNA was significantly associated with that of total survivin (r (s)=0.4178, P=0.0018), whereas inversely to that of survivin-DeltaEX3 (r (s)=-0.4506, P=0.0007). It was suggested that survivin-2a may act as an antagonist of survivin-DeltaEX3. The balance between antiapoptotic survivin iso-forms and nonantiapoptotic ones may play an important role in tumorigenesis and tumor progression. Promising value is hinted to analyze survivin and its variants in tumor early diagnosis and distinguishing malignant tumors from benign ones.

The results showed that survivin mRNA and protein were expressed in gastric cancer and para-cancerous tissues. The survivin-2B was dominantly expressed in para-cancerous tissues, whereas the survivin-△Ex3 was more frequently detected in cancer tissues. The positive rate of survivin-2a was 100% in both cancer and para-cancerous tissues,but its relative transcript expression level was not significantly increased in cancer tissues in comparison with para-cancerous tissues. The correlation analysis revealed that the expression of survivin-2a mRNA was significantly associated with that of total survivin (rs=0.4178, P=0.0018),whereas inversely to that of survivin-/EX3 (rs=-0.4506, P=0.0007). It was suggested that survivin-2a may act as an antagonist of survivin-△EX3. The balance between antiapoptotic survivin iso-forms and nonantiapoptotic ones may play an important role in tumorigenesis and tumor progression.

OBJECTIVETo investigate effects of systemic red light therapy on wound repair of burned patients and discuss its possible mechanisms of wound healing promotion.

METHODS138 burned patients were randomly divided into systemic red light treatment group (n = 69) and control group (n = 69). Patients in control group received routine therapy, while those in test group were given systemic red light therapy once a day, 30 minutes at a time until the wounds were recovered. The clinical findings and variables indicating wound repair were assessed on the 7th, 10th, 14th day, 21st day post-burn and the day when the wounds were healed.

RESULTSMean time of wound recovery were 19.86 +/- 2.43 days and 21.02 +/- 2.97 days respectively of those deep-thickness wounds in test group and control group, with statistically significance (P < 0.05). For the severity of the pain, VAS during time of dressing change on the 10th, 14th day post burn was lower in test group than that in control group which indicated less painful in test group (P < 0.05), suggesting pain relief effect of systemic red light therapy.

CONCLUSIONSystemic red light therapy was effective to promote wound healing of deep-thickness burn wounds and other similar acute wounds. Simultaneously, it is efficacious in pain relief and safe for those patients.
