The adrenal gland is a crucial endocrine organ, and adrenal tumors, mostly benign, often require surgical treatment. However, intraoperative localization of the adrenal gland is challenging due to its anatomical features. Laparoscopic surgery is widely used, but current laparoscopes lack real - time adrenal navigation. Near-infrared autofluorescence imaging (NIRAF) is a non-invasive technology that shows potential in adrenal localization, with limited reports globally and none in China. A 37-year-old female with a left adrenal nodule underwent retroperitoneoscopic left adrenal tumor resection. NIRAF technology, combined with laparoscopy, was used. The equipment had white light and near-infrared light modes.In the near-infrared light mode, the adrenal gland's autofluorescence was detected for intraoperative identification. Intraoperative NIRAF laparoscopy showed high-intensity fluorescence of the left adrenal tissue, clearly differentiating it from surrounding tissues.The surgery was completed within one hour without damage to surrounding organs. Postoperative monitoring of indicators such as blood pressure, aldosterone, adrenocorticotropic hormone, and white blood cell count was carried out. NIRAF technology has advantages in adrenal tumor resection, like improving surgical efficiency, reducing tissue manipulation, and lowering bleeding and infection risks. However, it has limitations such as weak light penetration and limited research. Further studies are needed to clarify its autofluorescence mechanism and evaluate its long-term effects.

Objective To investigate the correlation between the expression of (epidermal growth factor receptor-2,HER-2) and clinicopathological features and survival of colorectal cancer.Methods From Jan 2005 to Dec 2015,all colorectal cancer cases were enrolled that the expression levels of HER-2 were detected in Guangdong Provincial People's Hospital.Clinicopathological features of the tumors and survival of the patients were analyzed.Results A total of 1 463 cases were collected in 10 years,including 711 cases (48.6％) of HER-2 (-),470 cases (32.1％) of HER-2 (+),249 cases (17％) of HER-2 (+ +),and 33 cases (2.3％) of HER-2 (+ + +).Correlation analysis shows that the expression levels of HER-2 were significantly correlated with tumor differentiation and the depth of tumor invasion(T stage),but not correlated with gender,age,tumor location,N stage,M stage,TNM stage and overall survival,and disease-free survival.Conclusion The expression of HER-2 may be related to tumor differentiation and growth infiltration,but it cannot be used as a predictor of prognosis in patients with colorectal cancer.

Objective: To investigate the value and feasibility of C reactive protein (CRP) in predicting postoperative anastomotic leakage in rectal cancer patients with enhanced recovery after surgery (ERAS) for safer implementation of this ERAS. Methods: A cohort study on serum CRP of 455 rectal cancer patients undergoing laparoscopic radical resection according to the ERAS procedure at Gastrointestinal Unit of General Surgery Department, Guangdong General Hospital from August 2014 to June 2017 was retrospectively carried out. The serum CRP level was measured before operation and at postoperative days 1-7, and the serum CRP level of the groups with and without anastomotic leakage was compared to analyze its prediction for anastomotic leakage. Diagnostic standard of anastomotic leakage was based on the definition of postoperative anastomotic leakage in rectal cancer from International Study Group of Rectal Cancer (ISREC) : (1) Postoperative localized or diffuse peritonitis occurred, or fecal liquid was found from the abdominal drainage tube; (2) When anastomotic leakage was uncertain, peritoneal or pelvic computed tomography scan should be used to confirm. Results: All the 455 patients underwent surgery successfully, and 41 patients (9.0%) had anastomotic leakage postoperatively. Patients with anastomotic leakage were diagnosed (4.0 ± 2.0) days postoperatively, of whom 8 cases (19.5%) were diagnosed more than 5 days postoperatively. Serum CRP levels in patients with anastomotic leakage continued to increase within 1-4 days postoperatively[ (50.04 ± 27.98) mg/L to (122.75 ± 52.98) mg/L]and decreased 5 days postoperatively[ (92.02 ± 58.26) mg/L], both were higher than those of non-anastomotic leakage group, and the difference was statistically significant (all P < 0.05, except postoperative day 2) . The serum CRP level of non-anastomotic leakage group reached the peak on the second postoperative day[ (83.10 ± 37.45) mg/L] and decreased 3 days postoperatively[ (48.01 ± 27.59) mg/L]. The ROC curve was drawn with the anastomotic leakage as the state variable, and the CRP level as the detection variable. The area under the curve (AUC) at postoperative 1, 2, 4, 5, 6 and 7 days was 0.74, 0.58, 0.83, 0.82, 0.65, and 0.70, respectively. The maximum was at postoperative day 3[0.93 (95%CI: 0.86-0.99) ]. The Youden index was 0.72, and the threshold of CRP was 80.09 mg/L, as the cut-off point to predict anastomotic leakage, with sensitivity, specificity, and positive predictive value of 79.3%, 92.3%, and 74.2%, respectively. Conclusions Monitoring the postoperative serum CRP level can help predict the occurrence of anastomotic leakage after laparoscopic surgery for rectal cancer. When the serum CRP level is > 80.09 mg/L on the third postoperative day, the CRP level has the largest value in predicting postoperative anastomotic leakage, and the safety of ERAS has a certain clinical significance as well.
