Objective To assess the feasibility of intracavitary drainage using three equally-sized double pigtail stents in the treatment of ureteral stricture. Methods Placement of three identical double pigtail stents in ureters for indwelling for 10～12 weeks was carried out in 27 cases of ureteral stricture from March 2000 to June 2003. Results The patients were followed for 2～24 months, with a mean of 18 months. No lumbar distending pain or fever occurred after the removal of the drainage in 26 cases, with the IVP examination indicating patency drainage and no ureteral stricture. Re-examination of IVP 6 months after the surgery found no improvement of hydronephrosis in 1 case. The overall success rate was 96% (26/27). Conclusions Intracavitary drainage using three equally-sized double pigtail stents in the treatment of ureteral stricture is feasible.

Objective To explore change of peripheral blood CD5+B cells in the systemic lupus ery- thematosus(SLE)patients and the association of this change with the disease activity,Methods The percent- age of CD5~+B ceils in peripheral blood in 57 patients with SLE and 35 healthy controls was determined by flow eytometry.Levels of anti-dsDNA,complement C3 and C4,anti-nuclear antibody(ANA),anticardiolipin anti- body(ACL),were also measured.Results The percentage of CD5~+B cell in SLE patients(2.1?0.4)% was high- er than that in normal controls [(1.5?0.4)%](P＜0.05).In active disease group,the percentage of CD5~+B cells [(2.5?0.5)%] was significantly higher than that in inactive SLE patients [(1.4?0.5)% ](P＜0.01).The percent- age of CD5~+B cell associated with anti-dsDNA,ANA,ALA positively,with C3 negatively and had no associa- tion with C4.Conclusion The percentage of CD5~+B cells in the SLE is significantly high and has correlation and some relationship with the SLE.

Virus inactivation with photochemistry is being suitable for blood or blood products, methylene blue (MB)/light treatment has been used for viral inactivation of cellular blood components. Twelve new phenothiazines derivatives were designed and synthesized, and were used to test viral inactivation and red cell damage preliminary. Results showed that compound YWW-7 has a satisfactory activity, it could be developed as a new viral inactivation agent for blood products.

Objective To explore the effect of sex difference on learning and memory function and the brain tissue damage of neonatal SD rats with hypoxic-ischemic brain damage.Methods Sixty,7-day-old neonatal Sprague-Dawley rats,were divided into randomly:male control group (M group,n=15),female control group (F group,n=15),male hypoxic-ischemic brain damage group (MHIBD group,n=15) and female hypoxic-ischemic brain damage group (FHIBD group,n=15).A modified newborn rat model that had a combined hypoxic-ischemic brain damage as described by Rice-Vannucci was used.The Morris water maze was used to evaluate the ability of learning and memory.The brain MRI and transmission electron microscope(TEM) was used to evaluate the scope of brain tissue damage and the change of the synaptic ultrastructure.Results There were no differences in swimming distance,escape latency,synaptic cleft and damage brain volume between M group and F group(P＞0.05).Compare with M group and F group,MHIBD group and FHIBD group showed significant brain injury,longer escape latency ((39.38±11.40) s vs (14.86±4.42) s,(30.14±7.18)s vs (18.41±5.03) s),longer swimming distance ((15.31± 1.77) cm vs (3.68±1.50) cm,(13.18±1.79) cm vs (4.61±1.61) cm),and TEM showed the synaptic cleft was widened ((23.18± 1.36) nm vs (19.24± 1.51) nm,(21.40± 1.71) nm vs (19.87±0.94) nm),P＜0.05).MHIBD group was more seriously compromised than the FHIBD group(P＜0.05).The brain MRI showed the damage brain volume of MHIBD group were significantly larger than FHIBD group(P＜0.05).Conclusion After bypoxic ischemic brain damage,the tolerance of brain damage and / or post-injury recovery capabilities of female rats are stronger than males.

Aim This study was designed to investigate the inhibition of matrine on U251 glioma cell line and its mechanism. Methods MTT was used to measure the levels of the proliferation of U251 cultured with matrine in different concentrations.The effects of matrine on cell cycle of U251 were observed by FCM. The expression of proto oncogenes c myc was measured by RT PCR. Results The proliferation of U251 was obviously inhibited by matrine in a dose dependent manner. The inhibitory rate was (53 7?6 0)%,when cultured with matrine at 0 10 g?L -1 . The outcome of FCM showed that the proportion of G 0/G 1 phase cells were decreased. The proportion of S phase cells were reduced obviously,when cultured with matrine at 0 10 g?L -1 in 3 days.The outcome of RT PCR showed that the expression of proto onco gene C myc was notably decreased, when the dose of matrine was increased. Conclusion Matrine can inhibit the proliferation of U251 and inhibit the expression of proto onco gene C myc.

Objective To explore the clinical diagnosis and treatment of cyclic vomiting syndrome in children.Methods Thirty children proved with cyclic vomiting syndrome admitted from January,1998 to January,2003 were analyzed retrospectively.Results Cyclic vomiting syndrome was most likely to occur in 3-12 years old.The male to female ratio was 3∶2.The clinical manifestations were recurrent vomiting.Twenty-one cases had inducements,while 9 cases had not inducements.It was safe and efficient that curing cyclic vomiting syndrome with cyprohetadine and amitriptyline.Conclusions If these children with cyclic vomiting syndrome are inefficient to treatment,excluding metabolizable diseases,gastrointestinal,neurological diseases,they may be diagnosed cyclic vomiting syndrome,and cured with cyprohetadine and amitriptyline.
