Objective:To study the effects of curcumin on the activity of ATPase and the mechanism of apoptosis in U-251 cell.Methods:U-251 cells were treated with 20,40,80,100?mol/L curcumin for 24 h and the growth inhibition rates of U-251 cells were measured with MTT method.Cell apoptosis was inspected with flow cytometry(FCM).The activities of ATPase were determined by colorimetry method.Results:Curcumin inhibited the proliferation of U-251 cells and induced apoptosis of U-251 cells.level of ATPase in U-251 plasma Membrane was low remarkably.Conclusion:Curcumin induced apoptosis and inhibited proliferation of U-251 cell via inhibition of activation of plasma Membrane ATPase.

Five male and one female patients with IPVS caused by infarction of occipital cortex and optic radiations of brain were reported. The ages were in the range from 21 to 69 years. The evidence of diagnosis included sudden loss of visual acuity in both eyes, normal fundus, homonymous defect of visual field, infarction of brain in CT scan, without other positive signs of central nervous system or headache or eye pain before or at the time of attack. All the patients were treated by injection of Co- Anisodine Ⅰ and Ⅱ at acupuncture points with satisfactory effects. The therapy is safe, effective, and reliable. The clinical features and the treatment mechanism were disscused.

Thirty-six patients with normal vision in one eye coupled with advanced age-related macular degeneration(AMD)in the fellow eye,and 36 eyes with drusen in one eye coupled with macular drusen in the fellow eye,and 36 normal subjects(36 eyes) were measured by FM100-Hue test.All the tesed eyes had corrected vision of 1.0 or better and had drusen in the fundus.The results showed that the total errors score of FM100-Hue test of patients whose fellow eye suffered from advanced AMD compared with that of the patients whose fellow eye did not suffer from advanced AMD,difference between the two groups in the red and panchromatic regions was statistically significant(P

Visual function in early age-related macular degeneration (AMD) were observed by contrast sensi-tivity(cs), macular threshold, FM 100-Hue test, dark adaptation, and the Amsler grid. All patients with early AMD achieved corrected visual acuity of 1.0 or better. The results revealed that early AMD showed one or more of following: abnormal macular light sensitivity (MLS), hue discripmination, CS, threshold of dark adaptation, and Amsler grid, comparing with those of the normal controls. These tests proved useful for the early diagnosis of AMD, and their sensitivity was found to be in the following descending order: MLS, FM100-hue, CS, and Amsler grid.

XIAP(X-linked inhibitor of apoptosis protein)is one of the most important members of IAPs family.It inhibits cell apoptosis mainly by inhibiting the caspases activation and interfering with other apoptotic pathway,which plays a critical role in tumor development.Recently,genetic therapy targeting on XIAP for malignant tumors has deeply developed.Research on XIAP as a malignant and prognositic indicator is ongoing.

Forty-two cases of acute lumbar sprain patients were treated by strongly stimulating Shuigou(GV 26).Of them,32 cases were cured,5 cases got obvious improvement and 5 cases obtained no effect.The effective rate was 88.1％.

The surgical technique of total bladder replacement orthotopic intestinal neobladder has already been a well accepted method for urinary tract reconstruction after cystectomy in woad wide medical center in past 20 yeas.In this review,the update advance and viewpoint in some critical aspects of patients selection,reflux prevention,upper tract safety,continence,oncology safety,specific complications and quality of life were evaluated in the orthotopic bladder replacement.It is possible that the orthotopic bladder replacement become a new gold standard in urinary diversion after radical cystectomy.

Objective To discuss the value of urinary trace proteins in evaluating kidney function in the course of diabetes mellitus II rehabilitation.Method To assay level of urinary trace proteins in 50 cases of diabetes mellitus II and healthy control subjects. Result Level of trace proteins in 40 cases with diabetes mellitus ranged between normal values.They showed significantly increased urinary trace proteins(80％ ).Conclusion Urinary trace proteins is a sensible indicator for evaluating kidney function in diabetes mellitus II.

Objective: To understand the relationship between chloroquine resistance and the virulence of Plasmodium berghei. Met hods: Dynamic changes of histopathologic features of livers, spleens, brains, hearts, lungs and kidneys of mice infected with the chloroquine-sensitive (N) and the chloroquine-resistant (RC) strains of P. berghei were compared. Results: In mice infected with the N strain, deposition of heavy hemoz oin in livers and spleens, congestive edema in lungs, and congestion and embolis m in the brain capillaries were observed. The histopathologic features revealed ac ute inflammatory reaction. In mice infected with the RC strain, histopathologic variations of livers and spleens were associated with changes of parasitemia. In terstitial pneumonia was displayed in lungs. There were chronic histopathologic changes of the organs in the mice infected with RC strain. Conclusion: The mice infected by the N strain with potent virulence die due to adher ence of the erythrocytes to microvascular endothelia and embolism of the microva scula, especially in their brain. Immune responses of the mice infected by the R C strain with poor virulence may be a delayed-type hypersensitive inflammation a ssociated with CD4+Th1 at an early stage of the infection, but may become anti body-dependent immune response assisted with CD4+Th2, which play a key role in elimination of the malaria parasites at later stage of the infection.
