Objective To probe the application of superimposed flaps in hand surgery. Methods Form March 1998 to December 2003, we repaired 35 cases of skin defects with non trunk blood flaps and neurocutaneous vascular flaps. The area of flaps ranged from 1cm?1cm to 6cm?8cm. Results After operation, the flaps in 33 cases survived, but died in 2 cases due to unsuitable design. The follow ups ranging from 6 to 12 months showed that the quality and color of the survived flaps were similar to those of the normal tissue around. No swelling was found. Conclusion The superimposed flaps have reliable blood supply so that they are an ideal means to repair skin defects of hand.

Objective Excision repair cross-complementing gene-1(ERCC1) are key regulatory enzymes whose expression patterns are associated with overall survival(OS) in several malignancies.Their expression patterns and prognostic value in resected gastric adenocarcinoma(GAC) are not known and need to investigate.Methods A total of 109 patients who underwent resection for GAC in Liu′an People′s Hospital from January 2010 to June 2013 had tissue available for analysis.The primary objective was to assess for the differential expression of ERCC1 using by immunohistochemistry.The secondary objective was to assess for the association between OS and the expression of ERCC1.Results The median follow-up was 21.2 months,and the median OS was 28.8 months.Resected GAC exhibited differential expression of ERCC1(high expression,n=25(23%)).ERCC1 expression was not associated with OS(18.9 months vs.27.7 months,P=0.72).In a subset analysis of patients who received chemotherapy(n=73),high ERCC1 expression was associated with decreased OS(16.7 months vs.53.8 months,P=0.03).After controlling for known adverse pathologic features,high ERCC1 expression persisted as a negative prognostic factor in multivariate Cox regression analysis(HR=2.22,95% CI1.05-4.98,P<0.05).Conversely,in patients who underwent resection only(n=35),high ERCC1 expression demonstrated a trend toward improved OS(40.4 months vs.12.7 months,P=0.10).A positive prognostic influence also was present on multivariate analysis(HR=0.20,95% CI0.05-0.84,P=0.03).Conclusion Resected GAC exhibited differential expression of ERCC1.Among all patients,ERCC1 expression levels were not associated with OS.High ERCC1 tumor expression is associated with decreased OS in the patients who received chemotherapy but is associated with increased OS in those who underwent surgery alone.ERCC1 expression have prognostic value in resected gastric cancer,and further investigation is needed.

OBJECTIVETo investigate effects of the variation of immune function in high humidity environment in different time, and lay a foundation for further study of the related mechanism.
METHODThirty SD rats were divided into 3 groups (n = 10): 20 day group, 40 day group in 90% relative humidity chamber and control group in normal relative humidity. Peripheral blood and spleens were collected to detect the levels of T lymphocyte subsets by Flow Cytometery.
RESULTSIn peripheral blood of the 20 day group rats, the CD3+ %, CD4+ %, CD8+ % and CD4+/CD8+ were 52.91 +/- 6.27, 37.80 +/- 4.11, 14.85 +/- 3.73 and 2.72 +/- 0.82 separately. Expect CD3+ %, they all had significant differences (P < 0.05). In addition, the data of the 40 day group rats showed no diversity in statistics. In spleen, CD8+ % of the 20 day group rats was 6.23 +/- 2.87 with significant differences (P < 0.05) and IgG, IgA and IgM did not change a lot in blood serum of the high humidity groups except C3 of the 20 days group (P < 0.05).
CONCLUSIONIn high humidity environment, the immune function of the rats increased in the initial stage. As time went on, the immune function gradually went to normal level through the self adjustment.

OBJECTIVE:
To investigate the effectiveness of cisplatin on the expressions of Bcl-2 and Bax in cochlea and spiral ganglion cells (SGC) of guinea pigs.
METHOD:
Twenty guinea pigs were randomly divided into cisplatin (n = 10) and control groups (n = 10). Cisplatin group were administrated with a dose of intraperitoneal injection of 16 mg/kg, while the control group were received intraperitoneal injection of normal saline as placebo. Before and 7 days following injections, the ototoxic effect was measured with distortion product otoacoustic emission (DPOAE). Bcl-2, Bax in cochlea were detected by Western Blot. Immunohistochemical staining was used to detect the protein levels of Bcl-2 and Bax in spiral ganglion cells.
RESULT:
In control and cisplatin group, Bcl-2 protein levels were 0.727 8 ± 0.016 9 and 0.467 6 ± 0.020 1, Bax protein levels were 0.384 8 ± 0. 0217 and 0.735 6 ± 0.022 3 in cochlea respectively, both P < 0.01. In Control and cisplatin group, the grey values of Bcl-2 in SGC were 99.00 ± 2.42 and 149.80 ± 2.37 respectively, the grey values of Bax were 154.50 ± 2.80 and 104.50 ± 3.09 respectively, both P < 0.05.
CONCLUSION
Decreased expression of Bcl-2 and increased expression of Bax may be involved in cisplatin-induced apoptosis in cochlea and SGC of guinea pigs.

Objective To establish small-for-size (SFS) graft injury models in miniature pigs with high standardization, reproducibility and similarity to clinical situation. Methods Ba-Ma miniature pigs were introduced in this study and orthotopic liver transplantations (OLTs) were performed in 12 pigs with 30% liver volume allogeneil grafts (small portion of right paramedian lobe, right lateral lobe and caudate lobe) without veno-venous bypass. The profiles of intra-operational hemodynamics and metabolism were investigated. Animals were observed for 7 days with daily serum biochemistry and coagulation function exam. The survival rate related to operation itself and the SFS grafts were respectively calculated as well as the graft regenerative ratio at post-operational day (POD) 7. Results Graft weight as a percentage of the recipient's native liver weight (GW/RLW) and the total body weight (GW/BW) were (28. 63±4. 42)% and (0. 73±0.06)%. The mean operation time, anhepatic phase, and the time of blockage of infra-hepatic IVC were (191. 7±14. 2) min, (28. 3±3. 6) min, and (45. 0±5. 8) min. The survival rate related to the operation itself and the SFS graft were 83. 33% (10/12) and 40% (4/10), and the graft regenerative ratio at POD7 was (278. 06±42. 95) %. Contrast to the remarkable increase of heart rate and serum potassium during anhepatic phase, the mean arterial pressure, central venous pressure, rectal temperature, PH value and buffer excess had a significant decrease (P<0.01) with a gradual recovery after reperfusioa Serum ALT, AST, PT, Cr, and TB were significantly increased with a peak level at POD1 for the former 4 and POD2 for TB, and then began to decrease and favorably recovered at POD7, but TB, PT, and AST levels were still high when compared to those of prereperfusion (P<0. 05). Conclusion This model of OLT performed with 30% liver volume graft without veno-venous bypass was an ideal large animal model for series studies related to SFS graft injury.
