OBJECTIVE:To investigate inhibitory effects of matrine on the proliferation of human bladder cancer BIU-87 cells and its mechanism. METHODS:The cell viability was detected by MTT assay and inhibitory rate of cell proliferation was calculat-ed after human bladder cancer BIU-87 cells were treated with 0(negative control),0.5,1.0,2.0 and 4.0 mg/ml matrine for 24,48 and 72 h,respectively. After treated with 0 (negative control),0.5,1.0,2.0 and 4.0 mg/ml matrine for 48 h,the cell cycle and apoptotic rate were detected by flow cytometry;the expression of Survivin,Caspase-3 and Caspase-7 protein were detected by Western blot assay. RESULTS:Compared with negative control,the proliferation of BIU-87 cells were significantly inhibited after incubated with 1.0-4.0 mg/ml matrine for 24,48 and 72 h(P<0.05 or P<0.01),and inhibitory rate of cell proliferation increased in concentration and time-dependant manner;after treated for 48 h,the percentage of G0/G1 phase cells and apoptotic rate in-creased,while the percentage of cells at S phase and G2/M phase were decreased (P<0.05 or P<0.01);the expression of Cas-pase-3 and Caspase-7 protein increased,while the expression of survivin protein decreased after incubated with 0.5-4.0 mg/ml ma-trine for 48 h. CONCLUSIONS:Matrine can inhibit the proliferation of human bladder cancer BIU-87 cells,block the cell cycle and induce apoptosis;its mechanism may be related to the expression regulation of Survivin,Caspase-3 and Caspase-7.

The response was mainly related with the composition of their tattoos' color, as well as the proper choosing of laser wavelength and parameter.Conclusions According to feature of different tattoos,selecting reasonable wavelength and therapeutic parameters to treat the complicated tattoos can obtain better efficacy.

Objective To investigate effects of Kanglaite injection on proliferation, cycle and apoptosis of human breast cancer MCF-7 cells;To discuss its relevant mechanism. Methods Logarithmic growth phase cells were divided into control group and Kanglaite-treatment group (10, 20, 40μL/mL). Cells were cultured in RPMI-1640 for 24 h before drug treatment. The inhibition rate of Kanglaite injection on proliferation of human breast cancer MCF-7 cells was detected by MTT assay. Apoptosis and cell cycle of MCF-7 cells were detected by flow cytometry. Changes in cell nucleus were determined by Hochest staining assay. Protein expressions of Bcl-2 and Bax were detected by ELISA and Western blot. Results Kanglaite injection for 12 h, 24 h or 48 h resulted in a significant inhibition of MCF-7 cells proliferation (P<0.05, P<0.01);Compared with the control group, Kanglaite injection-treated cells showed increased percentage in G2/M and G0/G1 phases (P<0.001, P<0.01), but showed decreased percentage in S phase (P<0.01), and apoptosis rate increased (P<0.05, P<0.001). Kanglaite injection significantly decreased protein expression of Bcl-2, and enhanced protein expression of Bax of MCF-7 cells (P<0.01, P<0.001). Conclusion Kanglaite injection can inhibit the proliferation of human breast cancer MCF-7 cells, decrease cell cycle and induce apoptosis, the mechanism is related with decreasing protein expression of Bcl-2 and enhance the protein expression of Bax.

A 2-month-old baby girl developed universal keratotic plaques soon after birth. Physical examination revealed well-defined, dark erythematous, keratotic plaques with thick scales and mild infiltration at the periorbital, perioral, perianal and vulvar regions, as well as deep fissures of both hands and feet covered with thick yellowish crusts. Another case was a 24-year-old female, the mother of the baby, who presented with hyperkeratotic plaques at perioral and perianal regions, congenital alopecia universalis, mutilation of fingers and toes with massive thick keratotic yellow crusts and scales. Histopathology of skin lesions from the gluteal region of the baby showed psoriasiform hyperplasia of the epidermis, slight inflammatory infiltration of dermal papillae and superficial dermal perivascular regions. Immunohistochemistry demonstrated the positive staining for acidic keratin (AE1) in the prickle cell layer and granular layer and for CK10 in the upper prickle cell layer and granular layer. Electron microscopy showed increased cell space and decreased tonofilament. Both the baby girl and her mother were diagnosed with Olmsted syndrome.

Objective To measure the number of peripheral blood CD34+ hematopoietic stem/progenitor cells (HSC/HPCs) and membrane expression of CD34 on these cells in patients with SLE. Methods Lymphocytes were isolated from peripheral blood of 30 patients with SLE and 14 normal human controls. Flow cytometry using FITC-labeled antibodies was performed to determine the percentage of CD34+ HSC/HPCs and mean fluorescence intensity (MFI) of CD34 on these cells. Their correlation with clinical data was analyzed.Results The percentage of CD34+ HSC/HPCs in peripheral lymphocytes was (0.15 ± 0.10)% and (0.09 ±0.07)% in active and stable SLE patients, respectively, significantly lower than that in normal controls [(0.37 +0.17)%, F = 17.18, P ＜ 0.01], however, there was no significant difference between active and stable SLE patients (t = 1.51, P＞ 0.05). The MFI of CD34 was higher in active SLE patients than in the normal controls (41.35 ± 19.24 vs. 27.43 ± 7.57, F= 3.13, P ＜ 0.05), but no difference was observed between stable SLE patients and normal controls (F= 3.13, P ＞ 0.05). In patients with SLE, the percentage of CD34+ HSC/HPCs was negatively correlated with serum IgG levels (r = -0.588, P ＜ 0.01 ), but uncorrelated with SLE disease activity index (SLEDAI) or serum levels of complement, anti-dsDNA antibodies, anti-C1q antibodies, antinucleosome antibodies, etc. Conclusions The count of CD34+ HSC/HPCs is reduced while the MFI of CD34 antigen is elevated in SLE patients, hinting that there is a functional abnormality of HSC/HPCs in SLE patients, which may be involved in the pathogenesis of SLE.

Objective To measure the number of peripheral blood CD34+ hematopoietic stem/progenitor cells (HSC/HPC) expression of CD34 in the peripheral blood of patients with rheumatoid arthritis and exploreits relationship with clinical manifestations. Methods CD34+ HSC/HPCs in the peripheral blood of RA patients (n=32) and healthy controls (n=16) were detected using flow cytometry. The relationship between the frequency of HSC/HPCs, mean fluorescence intensities (MFI) of CD34 and clinical manifestations and rheumatoid factor (RF), anti-cyclic citrullinated peptide (CCP) antibodies, disease activity score (DAS) 28,X rays stages and healthy assessment questionnaire (HAQ) were analyzed. Student's t-test and pearont test were used for statistical analysis. Results Frequency of CD34+ HSC/HPC in the peripheral blood of RA patients was decreased compared with normal controls [ (0.13±0.09)% vs (0.38±0.21)%, P＜0.05 ], CD34 MFIwere higher in RA patients than those in the normal controls (57±33 vs 3111, P＜0.05). The frequency was positively correlated with the number of (RBC red blood cell), (Hb hemoglobin), and was negatively correlated with C-reactive protein (CRP), and the MFI of RA patients was positively correlated with healthy assessment questionnaire (HAQ) and X ray stages, but negatively correlated with the number of platelets.Conclusion CD34+ HSC/HPC of the peripheral blood of RA patients are significantly abnormal, which is characterized by decreased CD34+ hematopoietic stem cell, and the decrease is positively correlated with RBC and Hb, but negatively correlated with CRP. CD34+ hematopoietic stem cell may play an important role in the pathogenesis of RA.
