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 To investigate the changes and significance of serum C reactive protein (CRP) and calcitonin (PCT) levels in the elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods One hundred and twenty elderly patients with AECOPD in the respiration deplartment of our hospital from January 2013 to study One hundred and twenty elderly patients with AECOPD in our hospital from January 2013 to June 2015 were selected to conduct the study and performed the subgroup analysis according to the BODE index (body weight,dyspnea,airflow,motor function index),times of acute exacerbation within 1 year after treatment and recurrence time,and other 40 healthy subjects in the outpatient department were selected as the control group.The serum PCT and CRP levels were compared among various groups.Results Serum CRP and PCT levels in AECOPD patients with grade 1-4 of BODE index were significantly higher than those in the control group (P＜0.05),moreover in the intra-group comparison of serum CRP and PCT,the grade l＜grade 2＜grade 3＜grade 4,the differences were statistically significant (P＜0.05).Serum CRP and PCT had the significantly positive correlation with the grades of BODE index in AECOPD patients (r=0.482,0.317,P＜0.05).After treatment,serum CRP and PCT levels in AECOPD patients with recurrence occurred more than 3 months were significantly lower than those in the patients with recurrence occurred within 3 months,the difference was statistically significant (P＜0.05);serum CRP and PCT levels in the patients with more than once recurrence at 1 year after discharge from hospital were significantly higher than those in the patients with recurrence ≤once,the difference were statistically significant (P＜0.05).Conclusion The serum levels of CRP and PCT in the patients with AECOPD can reflect dyspnea,airflow limitation and motor function ability,and conducts the preliminary assessment on the patient's prognosis.

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.
