Objective To investigate distributions and drug resistance of pathogens in cirrhotic ascites comphcated with spontaneous bacterial peritonitis (SBP). Methods Results of bacterial culture and drug sensitivity tests of 117 aacitie specimens from cirrhotic patients with SBP were analyzed retrospectively. Results From the 117 ascitie specimens, 117 bacterial strains were isolated, among which 71 (60.68%)were gram-negative bacteria, 45 (38.46%) were gram-positive bacteria. The isolated strains were highly resistant to antibacterial agents, especially for Escherchia coli and Staphylococcu, the resistances to most antibiotics were above 60%. Conclusions High drug resistances were common for pathogenic bacteria in aacites of liver cirrhosis patients complicated with SBP.

BACKGROUND: Previous studies have proved that stress can affect immunity function and disturb homeostasis of bodies. Moderate exercise can alleviate the psychological stress reaction to some degree.OBJECTIVE: To observe the effects of moderate exercise on lymphocyte number in spleen and mesenteric lymph nod,interferon-y (IFN-γ) and interleukine-4(IL-4) level in serum, as well as Th1/Th2 balance in rats under chronic psychological stress.DESIGN, TIME AND SETTING: A randomized control animal experiment was carried out in the laboratory of Sports Human Science in Chengdu Sports University from May to October in 2007.MATERIALS: A total of 40 healthy male SD rats were divided by random digits table into 4 groups: control group, psychological stress group, exercise group and exercise+psychological stress group, with 10 ones in each group.METHODS: Before experiment, rats in exercise group and exercise+psychological stress group underwent 3 days of adaptive swimming training, 30 min/(t·d). During experiment, they were made swimming with no weight loading for 8 weeks, 60 min/(t·d).From day 2 post exercise on, rats in exercise+psychological stress group began to undergo the 21 days of chronic restraint stress,6 hours per day. At the same time, the chronic restraint stress models were established in the psychological stress group. Rats in the exercise group were fed for 22 days since the 8~(th) day of exercise ended. Rats in the control group were only fed without any intervention.MAIN OUTCOME MEASURES: The lymphocyte number in spleen and mesenteric lymph node was measured, and ELISA was employed to measure IFN-y and IL-4 levels as well as the ratio of IFN-y/IL-4 in serum.RESULTS: Compared with the control group, the lymphocyte number, the level of IFN-y and the ratio of IFN-y/IL-4 were significantly decreased in psychological stress group (P < 0.01 ), and the Thlf'rh2 balance was broken. Compared with the psychological group, the exercise+psychological stress group had got significantly higher lymphocyte number, IFN-γ level and ratio of IFN-γ/IL-4 (P<0.05). The lymphocyte number in spleen and mesenteric lymph node in the exercise group showed not a difference of significance compared with the control group, but a tendency towards going up. There was no difference of significance in IFN-γ level and ratio of IFN-γ/IL-4 among the exercise+psychological stress group, the exercise group and the control group.CONCLUSION: Moderate exercise can increase lymphocyte number in spleen and mesenteric lymph node significantly,up-regulate the IFN-γ level so as to regulate the disbalance of Th1/Th2, and maintain immunity homeostasis.

Objective To explore the feasibility, safety and advantage of thoracoscopes pulmonary bulla resection without thoracic closed drainage tube according to the fast track surgery (FTS) theory. Methods The clinical data of 53 patients with pulmonary bulla were retrospectively analyzed. Among them, 29 patients underwent the thoracoscopes pulmonary bulla resection without thoracic closed drainage tube (FTS group), and 24 patients underwent the thoracoscopes pulmonary bulla resection with thoracic closed drainage tube (tradition group). The oxygenation index at 24 h after operation, visual analogue score (VAS) at 24, 48 and 72 h after operation, postoperative complications, postoperative hospital stay and hospital costs were compared between 2 groups. Results There was no statistical difference in oxygenation index at 24 h after operation between FTS group and tradition group:(312.4 ± 16.4) mmHg (1 mmHg=0.133 kPa) vs. (330.6 ± 13.2) mmHg, P>0.05. The VAS at 24, 48 and 72 h after operation in FTS group was significantly lower than that in tradition group:(2.6 ± 1.1) scores vs. (4.3 ± 1.6) scores, (1.6 ± 0.9) scores vs. (3.8 ± 1.4) scores and (0.8 ± 1.0) scores vs. (2.9 ± 1.4) scores, and there was statistical difference (P<0.05). The incidence of postoperative complications, postoperative hospital stay and hospital costs in FTS group were significantly lower than those in tradition group:13.8%(4/29) vs. 37.5% (9/24), (3.2 ± 0.9) d vs. (6.2 ± 1.2) d and (1.3 ± 0.3) × 104 yuan vs. (1.5 ± 0.4) × 104 yuan, and there were statistical differences (P<0.05). Conclusions FTS used in thoracoscopes pulmonary bulla resection is feasible and safe, and has certain advantages.
