AIM: To observe the effect of phagotrophic ability of macrophage on pseudomonas aeruginosa which was cocultured with low concentration of erythromycin. METHODS: The pseudomonas aeruginosa ATCC 27853 was cultured in LB both with low concentration of erythromycin (Group A) and without erythromycin (Group B) for 18 h separately, then incubated with macrophage from murine abdominal cavity for 2 h. The ratio of phagocytosis of macrophage was determined by microscope detection. RESULTS: The ratio of phagocytosis of group A in which erythromycin was added was higher than the group B, and the pseudopodia of macrophage were increased in the group A under electron microscope. CONCLUSION: Low concentration of erythromycin may enhance the phagocytosis ability of macrophage in vitro by influencing the virulent factors of PA.

Objective To report the modified surgical technique currently used for the construction of an orthotopic ileal neobladder.So as to improve the vesical function of urinary storage and urination after total cystectomy. Methods Radical cystectomy and ileal neobladder with double “U” shape were performed in 20 patients with transitional cell carcinoma. After the detubularized ileal segment approximately 40 cm in length was arranged in a U configuration,the two medial borders of the U-shaped open segment were oversewn with a single layer seromuscular continuous 2-0 polyglycolic acid suture.The bottom of the U was folded over between the two ends of the U.Thus a spherical pouch, the neobladder, was fashioned. During that period, the neobladder anastomosed to the urethra.The ureters were implanted according to the improved stitching method. Results The operative time to form a neobladder was (90?15)min.Follow-up turned out that no perioperative or early postoperative mortality was observed, and no severe early complications occurred. The mean postoperative follow-up time was 25 (range,6 to 48) months.All the 20 cases achieved excellent continence except for 6 cases with temporary incontinence at night.Dysuria occurred in 1 case,and hydronephrosis on the left was found in 1 case.Six months later, the mean bladder capacity was 340 ml (range,250 to 450 ml). Conclusions The construction of an ileal neobladder using a smaller part of ileum that has been completely detubularized and fashioned by double U shape is easy and agreeable to perform.This mode of operation has low complication rates, achieves adequate capacity at low pressure, and provides satisfactory continence rates.

Objective To investigate the role of individualized psychological intervention in gastroscopy.Methods 286 patients first underwent gastroscopy were randomly divided into the intervention and control groups,143 patients in each group. Individualized psychological intervention were provided for intervention group,and the patients of control group were just given routine nursing care. All the patients were measured by self rating anxiety scale (SAS) ,which were as measuring standards before and after intervention. At the same time,the blood pressure and heart rate were compared before and after intervention. Visual analogue scale (VAS) was observed to investigate the satisfaction of patients after operation. Results Compared with control group,anxiety rate and degree,blood pressure and heart rate in intervention group were lower( P ＜ 0. 05 ). The test of VAS revealed that the satisfaction of patients in intervention group was significantly higher than that in control group ( P ＜ 0. 05). Conclusion Individualized psychological intervention could improve negative emotion and relieve anxiety and affliction of patients underwent gastroscopy, and the satisfaction degree for gastroscopy was improved.

To investigate the clinical efficacy of distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg for the treatment of traumatic chronic osteomyelitis of lower leg. A total of 25 patients with traumatic chronic osteomyelitis of lower legs were from Department of Burn and Plastic Surgery, Beijing Jishuitan Hospital from January 2002 to June 2008. All the patients were treated with distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg after thoroughly debridement. Among them, 6 patients were treated with myocutaneous flap with nutrient vessel of saphenous nerve, and 19 patients were treated with myocutaneous flap with nutrient vessel of sural nerve. The sizes of the flaps were 5 cm×3 cm-18 cm× 12 cm, with attached muscles were 3 cm×3 cm-8 cm×5 cm. The lengths of the pedicles were 5-12 cm. All transplanted myocutaneous flaps survived well. A 6-24 months follow-up of all patients was obtained. The shape and texture of the myocutaneous flaps were good. And there was no recurrence of osteomyelitis. Results suggested that the distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg had reliable blood supply and satisfied efficacy, which was a good method for repairing traumatic chronic osteomyelitis of lower leg.

Objective To investigate the role of N-methyl-D-aspartate receptor one(NMDA-R1 )in visceral hypersensitivity forming of Sprague-Dawley rat model induced by transient Trichinella spiralis intestinal infection.Methods Forty male Sprague-Dawley rats were divided into healthy control group,visceral hypersensitivity group,0.9％ NaCl group and MK-801 group.The rats in visceral hypersensitivity group,0.9％NaCl group and MK-801 group were given Trichinella spiralis to establish infection model.After eight weeks,the rats in 0.9％NaCl group and MK-801 group were given 0.9 ％ NaCl and MK-801 respectively.The abdominal muscular electrical activity of each group was observed under 20,40,60 and 80 mm Hg (1 mm Hg=0.133 kPa) colorectal distension pressure.After abdominal muscular electrical activity recorded,rats were sacrificed and the colon specimens were collected.The expression of NMDA-R1 at protein level was detected by Western blot.The data were analyzed by LSD test and Bivariate correlation.Results There was significant correlation between areas under curve (AUC) of abdominal muscular electrical activity electromyography and distension pressure in healthy control group,visceral hypersensitivity group,0.9％ NaCl group and MK-801 group (r=0.823,0.618,0.913,0.889 respectively,all P＜0.01).Under 20,40,60,80 mm Hg distension pressure,there was significant difference in AUC between MK-801 group and visceral hypersensitivity group (LSD test,all P＜0.05).The AUC of MK-801 group was lower than that of healthy control group,but there was significant difference (LSD test,P =0.029) only when distension pressure was at 80 mm Hg.The integral optical density value of NMDA-R1 protein of MK-801 group (1.238 ±0.210) was significantly lower than that of visceral hypersensitivity group (2.231±0.450) and 0.9％NaCl group (2.104±0.220) (LSD teat,P=0.025,0.046).The JA value of NMDA-R1 protein of visceral hypersensitivity group and 0.9％NaCl group was significantly higher than that of healthy control group (LSD test,P =0.007,0.014).Conclusion The visceral hypersensitivity forming was correlated with the high expression of NMDA-R1,and it could be adjusted by inhibiting NMDA-R1 expression in enteric nervous system.
