Objective To investigate the application of hypocaloric parenteral nutrition in postoperarive elderly patients with gastric cancer. Methods 59 elderly patients aged 60- 79 years with gastric cancer after operation were randomly assigned to receive 84 kJ · kg -1.d -1 hypocaloric parenteral nutrition (29 cases) and 126 kJ · kg-1 · d -1 standard-calorie parenteral nutrition (30cases),totally 6 d from postoperative 2 d. Complications, serum proteins, immune function,inflammation,blood glucose, liver function and recovery time of gastrointestinal function were observed during nutritional support. Results The postoperative complication rate were 37.9％(11/29) in hypocalorie group and 43.3 ％ (13/30) in standard calorie group ( P＞0.05),mainly pulmonary infection.There were no ditferences in levels of serum albumin,total protein and prealbumin between two groups at postoperative 3 d and 6 d (P＞0.05).Peripheral blood lymphocytes and T lymphocyte subsets CD3+,CD4+,CD4+/CD8- ratio were decreased after sugery,but CD8 1 values increased in two groups (P＞0.05).C reactive protein was increased significantly at postoperative 3 d compared with preoperation,and decreased at 6d than 3 d (P＞0.05).Blood glucose was decreased gradually at 3 and 6 d (P＞0.05).Postoperative liver function paraneters were elevated,no difference was found at 3 d (P＞0.05),and continued to rise at 6 d in standard calorie group than in hypocalorie group (P＜0.05). There was no difference in times of aerofluxus and cacation after operation between hypocalorie and standard calorie groups (P＞0.05). Conclusions Hypocaloric parenteral nutrition is a safe and effective method for nutrition support in postoperative elderly patients with gastric cancer.

OBJECTIVE:To observe the clinical efficacy and ADR of Mirabilite combined with intrapetitoneal in the treatment of elderly colorectal malignant ascites. METHODS:77 cases of patients with elderly colorectal malignant ascites were randomly di-vided into treatment group (n=40) and control group (n=37). The control group received the treatment of intraperitoneal alone, while the treatment group was based on the control group additionally received Mirabilite combined with intrapetitoneal. The clini-cal efficacy,quality of life (QOL),and ADR in 2 groups were compared and statistically analyzed. RESULTS:Compared with control group,the effective rate in treatment group was 77.5% and the disease control rate was 87.5%,with significant difference (P<0.05);the QOL score in treatment group was better than control group,with significant difference(P<0.05);the incidence of local ADR in Mirabilite for external use was low. CONCLUSIONS:Mirabilite combined with intraperitoneal has better efficacy in the elderly colorectal malignant ascites and better QOL.
