OBJECTIVETo investigate the activity and expression of Ca(2+)-Mg(2+)-ATPase in irradiated rat masseter muscle.

METHODSThe rats were irradiated locally with a single dose of 20 Gy X-ray. The activities of Ca(2+)-Mg(2+)-ATPase were measured with colorimetric method. The protein expression of Ca(2+)-Mg(2+)-ATPase was determined by Western blotting and immunohistochemistry.

RESULTSThe activities of Ca(2+)-Mg(2+)-ATPase in masseter muscle decreased by approximately 20% and 40% in irradiated rats on days 3 and 30 postirradiation. There was significant difference in the expression of Ca(2+)-Mg(2+)-ATPase protein between irradiated and nonirradiated rats on day 30 postirradiation. Ca(2+)-Mg(2+)-ATPase protein was found in the cytoplasm of masseter muscle.

CONCLUSIONSThe decrease of ATPase activity played an important role in the cause of radiation-induced skeletal muscle injury, while there was no significant reduction in the expression of Ca(2+)-Mg(2+)-ATPase protein in irradiated rat masseter muscle.

OBJECTIVETo review the efficacy of total anomalous pulmonary venous connection (TAPVC) repair and to conclude the factors impacting the peri-operative death rate.

METHODSThe clinical data of 145 infants under 1 year old who underwent the TAPVC repair from January 2001 to July 2008 was analyzed. There were 94 male and 51 female patients. The mean age when the repair was performed was (7 ± 3) months, and the average weight was (6.3 ± 1.6) kg. As to the pulmonary connection type, 77 patients were supracardiac (53.1%), 47 patients were cardiac (32.4%), 9 patients were intracardiac (6.2%), and the remaining 12 patients were mixed (8.3%). Pre-surgery echocardiography showed that 21 patients had pulmonary venous obstruction (12 patients were supracardiac type, 3 patients were cardiac type, 3 patients were intracardiac type, and 3 patients were mixed type).

RESULTSAll patients underwent two-ventricle anatomy correction (the cases of complex malformations had been excluded). Peri-operative mortality was 11.7% (17/145). Because of the significant improvement in the surgical techniques, anesthesiology, cardiopulmonary bypass and the management of ICU in January 2006, the population was divided into two groups: A (before January 2006) and B (after January 2006). Peri-operative mortality decreased from 19.0% in group A to 6.2% in group B(P = 0.020). After analysis, it was determined that the factors impacting mortality were which group the patient belongs to, whether he/she had preoperative pulmonary vein obstruction and how big the atril septel connection was. The operative technique to keep the anastomotic aperture adequate and prophylaxis pulmonary hypertensive episodes contributed to the improvement on the mortality rate. There had been no case of repeating the surgery because of pulmonary venous obstruction during peri-operative care period.

CONCLUSIONSImprovements of the surgical technique as well as the treatment in preoperative and postoperative have led to the reduction of the mortality. Preoperative pulmonary vein obstruction is still an important factor that contributes to early mortality.

Objective To explore the gender differences in the genes expression of sarcopenia with bioinformatics. Methods The gene expression profiles downloaded from Gene Expression Omnibus database were analysed with BRB-Array Tools and STRING,then the protein-protein interaction network was built with Cytoscape. Results There were 152 genes up-regulated and 67 genes down-regulated in sarcopenic men,and 90 up-regulated and 52 down-regulated in women,with the same 47 up-regulated and 21 down-regulated.The gene ontology(GO)terms were found to be more complex in the sarcopenic women.The function analysis showed the same module genes were enriched in regulation of fat cell differentiation,protein kinase inhibitor activity and protein kinase regula-tor activity.In the protein-protein interaction networks,dystrophin,vimentin and tropomyosin α-3 were the most important in men,and metallothionein 1H and dynein light chain in women. Conclusion The nosogenesis of sarcopenia is different between genders from differentially expressed genes,that may be important for the future study.

OBJECTIVETo investigate the effect of preoperative radiotherapy as an adjunctive approach on proliferation and apoptosis of cancer cells in rectal cancer.

METHODSEighty patients with (p)TNM stage II or III rectal cancer were enrolled from April 2000 to December 2002. The patients were divided into two groups, which were group received surgical treatment alone (40 cases) and group received preoperative adjuvant radiotherapy with a radiological dose of 40 G( y ) (40 cases). The expression of Ki- 67 protein in rectal cancer was detected immunohistochemically and apoptosis was detected by TUNEL technique.

RESULTSIn radiotherapy group, the tumor volume shrank markedly in 14 cases, partially in 18,slightly in 8 with an overall efficiency rate of 80% .There was significant positive correlation between spontaneous apoptosis and Ki- 69 marker index in cancer tissues before radiotherapy(gamma =0.563P=0.027). The expression of Ki- 67 in rectal cancer tissues was significantly lower after radiotherapy than that before radiotherapy, as well as in the control group(P=0.017 vs. P=0.011).The expression of Ki- 67 in paratumor tissues 2cm from tumor was significantly lower after radiotherapy than that before radiotherapy. Apoptosis index (AI) in rectal cancer tissues was significantly higher after radiotherapy than that before radiotherapy, and that in the control group (P=0.013 vs. P=0.018).

CONCLUSIONRadiotherapy can inhibit proliferation and induce apoptosis of rectal cancer cells. The expression level of Ki- 67 can be considered as a screening index for preoperative radiotherapy.
