Objective To investigate the clinical characteristic and prognosis of nonsteroidal antiinflammatory drugs( NSAIDs)and aspirin associated peptic ulcer bleeding. Method All patients with peptic ulcer bleeding were studied by the same researcher after admission and discharge. Results Fifty-one cases with NSAIDs and aspirin medication of the total peptic ulcer bleeding patients ( 147 cases) were included (34. 7% ). Compared with patients not associated with NSAIDs and aspirin medication, they are older [(41.2 ± 1. 9 ) years vs ( 59.4 ± 2. 2 ) years, P ＜ 0. 001], more commonly associated with hypertension ( 10. 4% vs 39. 2% ,P ＜0. 001 ), coronary heart disease ( 10. 4% vs 17.6% ,P ＜0. 001 ) ,diabetes (4. 2%vs 19. 6%, P = 0. 005 ); and had more severe anemia (7. 3% vs 23. 5%, P = 0. 008 ). Fewer patients in NSAIDs group had epigastric pain (61.5% vs 27.5%, P ＜ 0. 001 ), while there was more re-bleeding (9.4% vs 15.7%, P = 0.034). In all bleeding patients, factors associated with re-bleeding, surgical intervention and death included NSAIDs and aspirin medication, and low platelet count. In patients with NSAIDs and aspirin medication, re-bleeding was associated with previous ulcer history ( P ＜ 0. 05 ).Conclusion Peptic ulcer bleeding patients with NSAIDs and aspirin medication were more severe ill, and less likely to present with epigastric pain.

Objective　To probe into roles of hCKLF-1 in the development of systemic lupus erythematosus in BXSB mice in vivo.Methods　The recombinant eukaryotic expression plasmid for hCKLF-1 (pCDI-hCKLF-1) was transferred and expressed in lupus-prone BXSB mice with the technique of muscle-mediated transgene by electric pulse;the levels of serum IgM and IgG anti-DNA antibodies as well as serum BUN and urine protein were detected.Results　hCKLF-1 expression in vivo did not make any effects on the levels of IgM and IgG anti-DNA antibodies in female and male BXSB mice,but markedly enabled abnormal elevation of urine protein in male BXSB mice in short time,suggesting its ability for accelerating glomerulonephritis.Conclusion　hCKLF-1 may be one of inflammation mediators,playing an important role in the lupus glomerulonephritis of male BXSB mice,and its target cells may be monocyte and macrophage.

Objective To study the clinical features and treatment of multiple schwannomas (neurilemmomas). Methods 9 patients with multiple schwannomas treated with surgery from 1975 to 1999 were reviewed retrospectively. Results In 7 of the 9 cases of schwannomas, the number of tumor lesions was seen more than that diagnosed preoperatively. All the patients had surgical resection; 5 had enucleation and 4 had tumors excised with the invovled nerve. Recurrence occured in 4 patients. Conclusion Because of the difficulty in predetermination of the exact lesional number, thoroughly preoperative examination including MRI is nessesary. Enucleation is recommended to those tumors involving important nerves. There is a high rate of recurrence.

Objective To investigate the relationships between incidence of post-stroke depression(PSD)and sex,lesion sites and stroke severity,as well as the treatment of anti-depression in elderly patients.Methods 112 stroke patients were assessed by Self-rating Depression Scale(SDS)and Hamilton Depression Scale(HAMD)to evaluate the severity of depression,and the related features were analyzed in 42 diagnosed PSD patients.Results The incidence of PSD was 37.5% in elderly patients,90.5% of which were mild-and moderate-depression(P<0.01).The incidence of PSD was significantly different between genders(P<0.01).PSD incidence in patients with basal ganglia lesion was significantly different compared to that with lesions of cerebral cortex,cerebellum or brainstem(P<0.01).PSD incidence in patients with left cerebral hemisphere lesion was similar with that in those with right or both sides of cerebral hemisphere lesions(P>0.05).PSD incidence was different between patients with mono-and poly-lesions.PSD incidence in patients with severe degree of neurological dysfunction was significantly different compared to that with moderate or mild degrees of neurological dysfunction(P<0.05,P<0.01).Based on the treatment of stroke,the HAMD scores decreased significantly after mind-cure and anti-depression medication treatments(P<0.01).Conclusion PSD incidence is high in elderly patients,and most of PSD are mild and moderate.Females are susceptibility with PSD than males.PSD incidence is higher in patients with basal ganglia lesion,but is not correlated with the infracted area.The more lesions in cerebral,and the severer degree of neurological dysfunction,the PSD incidence is higher.The treatments of mind-cure and anti-depression medications based on the treatment of stroke are safe and effective for PSD patients.
