RESUMO

@#Objective    To explore the relationship between Beclin 1 level and lymph node metastasis in patients with non-small cell lung cancer. Method    A total of 204 surgical specimens of patients with non-small cell lung cancer from September 2011 to September 2016 were collected in our hospital. There were 116 males and 88 females . Beclin 1 levels were detected by Western blotting. There were 116 males and 88 females at average age of 55.3±11.2 years. The patients were divided into three groups including a group N0 (no lymph node metastasis), a group N1(intralobar and interlobar lymph node metastases, and no mediastinal lymph node metastasis), and a group N2 (mediastinal lymph node metastasis). The differences of Beclin 1 levels in tumor tissues and lymph nodes of patients with N0, N1 and N2 were statistically analyzed. Results    Among 204 patients of lung cancer, 36 patients were squamous cell carcinoma and 168 patients were adenocarcinoma. The levels of Beclin 1 in tumor tissues of N0, N1 and N2 groups decreased gradually with a statistical difference (P<0.05). In the three groups, the levels of Beclin 1 in the lung hilum and intrapulmonary lymph nodes (N1 Beclin 1) of N1 and N2 groups were less than that of N0 group with a statistical difference (P<0.01). In the three groups, the level of Beclin 1 in the mediastinal lymph nodes (N2 Beclin 1) of N2 group was less than that of the N0 and N1 groups with a statistical difference (P<0.01). In the N1 group, the level of N1 Beclin 1 was less than that of N2 group (P<0.01). In the N2 group, though the level of N1 Beclin 1 was less than N2 Beclin 1, there was no statistical difference (P>0.05). Conclusion    Beclin 1 level can be used as a reference index to judge the benign and malignant lung masses, and lymph node Beclin 1 level can be used as an important reference index to help determine whether there is lymph node metastasis in lung cancer.

RESUMO

@#Objective    To investigate the correlation between end-to-side anastomotic angle and postoperative anastomotic stricture in the surgery of esophageal carcinoma. Methods    From January 2011 to June 2015, 130 patients with middle/lower esophageal carcinoma or gastric cardia cancer underwent operations in Shanghai Pudong Hospital and Lishui Central Hospital, Zhejiang Province. Depending on the end-to-side anastomotic angle, they were randomly divided into two groups (n=65 in each): a 0 degree group (49 males and 16 females, aged 64.5±8.3 years) and a 45 degrees group (52 males, 13 females, aged 61.7±9.1 years). Stooler degree grading was adopted to evaluate the anastomotic stricture in each group 6 months postoperatively. Results    There were two patients with anastomotic fistula in each group (P>0.05). Pathology showed squamous carcinoma in 116 patients and adenocarcinoma in 14 patients. The postoperative esophageal stricture in the 45 degrees group was significantly less than that in the 0 degree group. There was no statistical difference in the duration of chest tube (5.9±6.7 d vs. 5.8±6.8 d) and recovery of intestinal peristalsis (2.6±0.8 d vs. 2.6±0.7 d) between the 45 degrees group and the 0 degree group. Conclusion    Esophagogastric anastomotic angle is related to the formation of postoperative anastomotic stricture. Oblique anastomosis with 45 degrees is helpful to decrease the severity of stricture.
