Twenty-fine samples of stomach and 25 samples of adenocarcinoma stomach were employed for this study. The former have been collected from the patients of duodenal ulcer. Specimens were taken from the large curvature and pylorus. In the adenocarcinoma of stomach, materials were taken from the cancer focus and the cancer margins, fixed in 10% formalin-GaCl_2 Solution, embedded in paraffin and cut at 5? in thickness. Then they were examined with defferent reactions of histochemistry; PAS, Alcian blue (AB), Toludine blue (TB) and Barnett's method. The surface of gastric mucosa obtained from patients of duodenal ulcer after subtotalgastrectomy was covered with a substance which consists of neutral and acid mucopolysaccharide and protein. The epithelial cells of the mucosa contains large amount of neutral muco-polysaccharide. The cells of the neck of gastric gland contain quite a bit of acid muco-polysaccharide, but the cells of the deep segments of the glands do not show any of it. The cells of adenocarcinoma of stomach contain a different deal material mixture which consists of acid muco-polusaccharide and protein. The surface of the cavity in the well-differenlialed cancer glands was covered by a positive substance in TB, AB method, which forms a thin layer of membrance. An evenly distributed substance in the cavity of carcinoma gland was shown with positive reactions of PAS, AB, TB and protein. The degenerated cells show a positive reactions of PAS and protein. The cells of low-differentiated cancer were surrounded with a superficial layer of the acid mucopolysaccharide. The interstitia in the invaded margines often showed clear, distinct positive PAS and TB reactions. It indicates that it cortains more chondroitin sulfuric acid and the hyaline acid. In the superficial layers of mucosa of the cancer tissue, the epithelial cellswere often to have less positive substance than that of the membrane in the parts of cancer margine, it means a lesser amount of neutral-polysaccharide. But the acid muco-polysaccharide in the surface of cancer and its metaplastic margin clearly increases in amount than the metaplastic area far away from the cancer focus. This report discussed the significance of the increased muco-polysaccharide in the tissue of the gastric cancer.

Objective To investigate the effect of breathing filter(BF) on prevention of the respiratory tract infection in elder patients undergoing general anesthesia.Methods One hundred elderly who underwent the operation of gastrointestinal tumors were involved in the current study.They were randomly divided into control and experiment group and each for 50 cases.Patients in experiment group were given BF while in control group were not given.Bacteria on the tip of endotracheal tube and in the anesthesia machine circuits close to endotracheal tube were checked.The rate of the respiratory tact,infection of operative patients were recorded.Results After operation,a large number of bacterial growth in endotracheal catheter ends in both groups.The level of bacteria in the anesthesia machine circuits of control group was (305.2 ± 12.4) CFU/cm2,higher than that in experiment group ((10.2 ± 2) CFU/cm2 ; t =166.077,P ＜ 0.001).No patients in experimental group got respiratory tract infection in the follow up periods,but 5 patients (10.0％) in control group were infected,and the difference was significant (x2 =5.263,P ＜ 0.05).Conclusion BF can effective filtrate the bacterial in breathing circuit,significantly reduce the incidence rate of respiratory tract infection.

Objective To evaluate the effects of inhaled aerosolized different doses of lidocaine on lung injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅱ or Ⅲ patients of both sexes,aged 18-58 yr,weighing 35-70 kg,undergoing elective cardiac valve replacement with CPB,were randomly divided into 3 groups (n =10 each) using a random number table:control group (group C),lidocaine 100 mg group (group L1) and lidocaine 200 mg group (group L2).Anesthesia was induced with iv injection of midazolam,etomidate,fentanyl and vecuronium.The patients were endotracheally intubated and mechanically ventilated.The aemsolized normal saline 10 ml,2％ lidocaine 5 ml + saline 5 ml and 2％ lidocaine 10 ml were inhaled in C,L1 and L2 groups,respectively,starting from 10 min after induction.At 10 min after induction (T0),1 and 10 min after opening of vena cava (T1,2),and the end of CPB (T3),blood samples were collected from the left radial artery (LRA) and right atrium (RA) for determination of plasma interleukin8 (IL-8),tumor necrosis factor-α (TNF-α) and malondialdehyde (MDA) concentrations (using ELISA) and the expression of CD11 b on polymorphonuclear leukocytes (by flow cytometry).Blood samples were collected from the left radial artery at T0,immediately after beginning of CPB,at T3 and at 2 and 6 h after termination of CPB for blood gas analysis.The oxygenation index (OI),respiratory index (RI) and dynamic lung compliance (Cdyn) were calculated.Results Compared with group C,the ratio between IL-8 concentration in LRA and in RA (concentration of IL-8LRA/RA) was significantly decreased at T2,3,the concentration of MDALRA/RA was decreased at T3 (P ＜ 0.05),no significant change was found in the expression of CD11bLRA/RA at each time point (P ＞ 0.05),and RI was decreased at T3 in L1 and L2 groups (P ＜ 0.05).There were no significant differences in the concentration of IL-8LRA/RA,TNF-αLRA/RA and MDALRA/RA,expression of CD11bLR A/RA,RI,OI and Cdyn at each time point between group L2 and group L1 (P ＞ 0.05).Conclusion Aerosolized lidocaine inhalation can attenuate lung injury and improve lung function in patients undergoing cardiac valve replacement under CPB by reducing inflammatory responses and lipid peroxidation in lung tissues.
