Objective To explore the new operation approach and the effect of surgical therapy on cardial carcinoma. Methods A total of 78 patients with cardial carcinoma received surgical therapy by the transabdominal route from January 1992 to January 2002, of which 30 cases were treated by total gastrectomy by substitution of P shaped jejunum and 48 cases were treated by subtotal gastrectomy. All patients were followed-up postoperatively from 6 months to 5 years. Results The average length of resected lower part of the esophagus above the tumors was over 5cm, without cancer tissue retained in resected edge. The rate of intramediastinal lymph node metastasis was 18.4%. 5-year survival rate of the patients with total gastrectomy was higher than that of the patients with subtotal gastrectomy, and the morbidity rate of reflux esophagitis of the former was lower than that of the latter. Conclusions The patients of cardial carcinoma in Ⅲ stage or Ⅱstage with lymph node metastasis of 5 or 6 groups should be treated by radical total gastrectomy. The P shaped reconstruction of stomach with jejunum as a replacement satisfies the physiological needs and causes less compications.

Objective To evaluate the value of ice-compression therapy in mice skeletal muscle after acute crush injuries and correlate treatment effect with different compression time by MR DTI. Methods Forty Weistar mice were randomly divided into 4 groups by random number table method: control group (A), 5 min compression time group( B), 15 min compression time group(C) and 30 min compression time group(D). Diffusion tensor imaging examinations were performed before, immediately after, 24, 48 and 72 hours after injuries. ADC and FA values were calculated by fiber tracking tool. The morphological changes were confirmed by histopathology, and immunohistochemical methods were used for the assessment of Desmin expression with mean of A value. Statistical analysis by LSD-t test and Spearman rank correlation.Results (1) For every group before injuries, ADC valueswere (1.38±0.04) ×10-3,(1.38±0.08) ×10-3, ( 1.34 ± 0. 05 ) × 10 -3, ( 1.36 ± 0. 09 ) × 10 -3 mm2/s respectively, FA value were 0. 46 ± 0. 05,0. 45 ±0. 03,0. 45 ± 0. 05,0. 48 ± 0. 04 respectively. ADC values increased significantly and FA values reduced in each group immediately after injuries compared with pre-injury values. ADC values were ( 1.84 ±0. 10) × 10-3, ( 1.79 ±0. 09) × 10-3, ( 1.55 ±0. 07) × 10-3, ( 1.57 ±0. 04) × 10 -3mm2/s respectively,FA value were 0. 21 ±0. 04, 0. 26 ±0. 03, 0. 31 ±0. 02, 0. 30 ±0. 04 respectively. ADC values were still higher and FA values lower than pre-injury values at 24 hours after injury in A, B groups. ADC values were (1.54±0.13) ×10-3, (1.57±0.13) × 10-3mm2/s, FA value were 0.25 ±0.03, 0.26±0.02. (2)DTT showed fibers distorted and the number of fiber bundles reduced, some separation and displacement in each group immediately after injury. C, D groups improved more than A, B groups over time. (3) The disorder arrangement of skeletal muscle cells with edema and filaments separation were found in HE staining after injury, but the degree mitigated in C, D groups. Desmin staining became lighter with fuzzy edge immediately and 24 hours after injury, and changed more than 72 hours after injury. (4) The correlation coefficients of ADC, FA values and A value were respectively - 0. 789 and 0. 763 ( P < 0. 05 ). Conclusions DTI can non-invasively reflect the pathological changes after acute crush injuries of muscles of mice and ice compression therapy. It is a useful method to guide ice compression treatment after acute crush injuries.
