Objective To study the feasibility and safety of laparoscopy-assisted D2 radical gastrectomy for advanced gastric cancer. Methods From June, 2006 to July 2009, 11 patients with gastric cancer received laparoscopy-assisted gastrectomy for gastric cancer. According to UICC TNM classification of gastric cancer, 6 cases were with Stage Ⅱ, 2 cases with Stage Ⅲ A, 1 case with Stage Ⅲ B, and 2 cases with Stage Ⅳ. Under the assistance of laparoscope, dissociation of the stomach and lymph nodes clearance were performed first; then gastrectomy was performed on a 6 cm incision, samples were collected, and alimentary tract was inoculated. Results Among the 11 cases, 2 cases were performed radical total gastrectomy, 1 case was performed proximal partial gastrectomy, 7 cases were performed distal partial gastrectomy and 1 case with open surgery. The mean operation time: 350 min for total gastrectomy, 320 min for proximal partial gastrectom,266 min for distal partial gastrectomy. The mean number of harvested lymph nodes was 21.3 (11-38), incisal edge was 5.6 (4.0-9.6) cm. The mean time was 72 (36-110) hrs for gastrointestinal function recovery, 59 (26-86) hrs for patients to take general activity, and 76 (48-116) hrs to take liquid food. No complication was observed. Conclusion Laparoscopy-assisted D2 radical gastrectomy for advanced gastric cancer is safe and feasible. Compared with open surgery, it also has the advantages of small wound and fast recovery.

Objective To investigate neutrophil lymphocyte ratio (NLR) in early-stage diabetic nephropathy and its clinic significance. Methods The 145 subjects were divided into two groups:the healthy control group (n=54) and early stage diabetic nephropathy group (n=91). The numbers of neutrophils (N) and lymphocytes (L) as well as the NLR values of peripheral blood and other biochemistry index were examined. Factors of early stage diabetic nephropathy were calculated us?ing variance and logistic regression analysis. Results Creatinine(Cr), total cholesterol(TC), triglyceride(TG), LDL-C, neu?trophils number and CRP in DN group were significantly higher than those of the control group and lymphocytes numbers of DN group were significantly lower than that of the control group (P<0.05 respectively);NLR values were significantly higher in diabetic nephropathy group compared with those of healthy control group(2.52±0.57 vs 1.82±0.60,t=6.997, P<0.01). Lo?gistic regression analysis showed that the risk factors of DN include NLR, TG and total cholesterol. NLR ( P <0.001, OR=8.951, OR 95%CI:3.595-22.287) was significantly associated with DN. Conclusion High NLR values may be a predic?tive and reliable marker ofearly-stage DN.

Objective:To explore the effects of magnanimous therapy on the magnanimous and enterprising traits of lung cancer patients and the analysis of related factors.Methods:Totally 197 patients with lung cancer were divided into individual group ( n=62), team group ( n=75) and control group ( n=60). Comparison and correlation analysis were applied to the data before and after the electroencephalogram and the magnanimous questionnaire, the cancer response questionnaire, the T-type psychological scale, the cancer heart state questionnaire and the cancer patient's life function index scale. t test, analysis of variance and Pearson correlation analysis were processed by SPSS 23.0. Results:After treatment, the " enterprising" dimension and " magnanimous" dimension of individual group and the " enterprising" dimension of the team group ((3.035±0.309), (3.041±0.265), (3.173±0.371)) were higher than that before treatment((2.934±0.326), (2.908±0.315), (3.130±0.387), all P<0.05). There was negative correlation between " magnanimous" dimension of the magnanimous questionnaire and " subconscious" dimension of the T-type psychological scale in individual group( r=-0.280, P<0.05). In team group, the " enterprising" dimension of the magnanimous questionnaire was negatively correlated with " Psychological" and " Yield" dimension of the cancer heart state questionnaire( r=-0.279, -0.285, P<0.05), and positively correlated with " Facing" of the cancer response questionnaire, " Good physical condition and ability" and " Psychological well-being" dimension of the cancer patient's life function index scale( r=0.367, 0.402, 0.379, P<0.05). There was a negative correlation between the " enterprising" dimension of the magnanimous questionnaire and the beta wave value in individual group. Conclusion:The magnanimous therapy can improve enterprising and magnanimous level of patients with lung cancer, and the effects are related with the above-mentioned psychosomatic factors.

Along with the changes in the epidemiology of gastric cancer in China, the early diagnosis and treatment rate of adenocarcinoma of esophagogastric junction has elevated signifi-cantly, while its surgical methods have also altered and become a hotspot. Total gastrectomy has become the primary surgical allocation for adenocarcinoma of esophagogastric junction. In recent years, a series of studies on proximal gastrectomy and digestive reconstruction after distal stomach preserving have been explored due to recent concept of functional preservation. The main concern about this surgical method is the efficacy of anti-reflux and its influence on nutritional prognosis. Interpositioned jejunum and double tract reconstruction have curative effects. However, they become obstacles for total laparoscopic surgery due to the complexity of surgical operation. Thus there is increasing concern to explor the way to reduce the reflux rate and improve the nutritional status of patients. Baesd on related research at home and abroad, combined with their own experiences, the authors comprehensively analyze and illustrate self-palling and latter transection with esophagojejunostomy and double anti-reflux double tract reconstruction of total laparoscopic proximal gastrectomy.
