Effect of As(2)O(3) on expressions of COX-2 and matrix metalloproteinases in SGC7901 and K562 cells / 中国实验血液学杂志

This study was aimed to investigate on effect of As(2)O(3) on expressions of COX-2, MMP-2 and MMP-9 in SGC7901 and K562 cells. SGC7901 and K562 cells were cultured in RPMI 1640 medium and were inoculated in culture medium with different concentrations of As(2)O(3) and at different times. Expressions of COX-2, MMP-2 and MMP-9 in SGC7901 and K562 cells were measured by using Western blot, while the levels of COX-2 mRNA and MMP-2 mRNA were measured with fluorescence quantitative RT-PCR. The results showed that the expression of COX-2, MMP-2 and MMP-9 decreased in dose- and time-dependent manners after treating with As(2)O(3). The levels of COX-2 mRNA and MMP-2 mRNA reduced in groups treated with As(2)O(3). In conclusion, As(2)O(3) inhibits expressions of COX-2, MMP-2 and MMP-9 in K562 and SGC7901 cells, suggesting that As(2)O(3) inhibits tumor development through its effect on angiogenesis involved in solid and hematologic malignancies.

Effect of arsenic trioxide on vascular endothelial growth factor-C and its receptor (VEGFR-3) in nude mice with gastric cancer / 中国实验血液学杂志

This study was aimed to investigate the effect of arsenic trioxide (As2O3) on expression of vascular endothelial growth factor-C (VEGF-C) and its receptor VEGFR-3 in gastric cancer in order to clarify the role of As2O3 in lymphangiogenesis and metastasis of tumor. The gastric cancer model was established in nude mice by using gastric cancer cell line SGC-7901. As2O3 was injected to the two treatment groups (2.5 mg/kg and 5 mg/kg) and the same volume of saline solution was injected to the control group. Expression of VEGF-C and VEGFR-3 were detected by immunohistochemistry and were analyzed with QWin550cW image Acquiring & Analysis System. The results showed that the expression of VEGF-C and VEGFR-3 in cancer cells significantly reduced in the arsenic -treated groups. The expression of VEGF-C and VEGFR-3 in 5 mg/kg group was significantly less than that in 2.5 mg/kg group. The gray ratio analysis confirmed that there were significant difference between control group and two treated group, as well as between 2.5 mg/kg-treated group and 5 mg/kg-treated group. It is concluded that As2O3 can inhibit expression of VEGF-C and VEGFR-3 of human gastric cancer xenografts in nude mice, which suggests that As2O3 may inhibit the lymphangiogenesis by suppressing the expression of VEGF-C and VEGFR-3.

<p><b>OBJECTIVE</b>To study the effect and safety of graded therapy featuring integrative traditional Chinese and Western medicine for the treatment of hemophilic arthritis.</p><p><b>METHODS</b>Forty patients with hemophilic arthritis were hospitalized randomly, with their blood coagulation factor activity determined by one-stage method and their arthritis classified into 4 stages. The treatment was applied according to the stage of arthritis and finding of intra-articular cavity puncture. For stage I, based on the principle of RICE (rest, ice, compression and elevation), 1.8 g of Xuefuda was medicated orally once per day, intravenous dripping of 250 mL of hemostasis mixture twice a day and 1.2 g of clindamycin per day were also given for hemostasis and anti-inflammation. For stage II-III, Kangyanling was additionally administered via intra-articular cavity injection twice a week, 2 mL every time, for 5-6 times in total. For stage IV, the drug for intra-articular cavity injection was replaced with 25 mg of sodium hyaluronate and the frequency of injection reduced to every two weeks, for 5-6 times in total. Coagulation factors III and IV as well as blood plasma were not given in the whole treatment course. Short-term therapeutic effects and adverse reaction in patients were evaluated, and the long-term effects were followed-up after patients left the hospital with 6-month consolidation therapy by Xuefuda.</p><p><b>RESULTS</b>After a 3-week treatment, 33 patients (82.5%) were completely remitted; 5 (12.5%) were partially remitted and 2 (5.0%) un-remitted, setting the short-term effective rate at 95.0% (38 cases). The 6-month follow-up showed that except for a relapse in 2 and 4 patients of stage III and IV respectively, long-term remission displayed in all the other 34 patients, with the remission sustaining rate being 85.0%. No complication such as an infection, bleeding or aggravating pain occurred in the 215 times intra-articular puncturing conducted in the 40 patients. Normal figures were shown in liver and kidney function, electrolytes, ECG, blood glucose and routine test of blood and urine throughout the course.</p><p><b>CONCLUSION</b>The graded treatment of integrative medicine for hemophilia with non-blood preparation has a favorable effect and is safe or without any adverse reaction, which opens a high efficacy and new safe path and thinking for the treatment of and deformity prevention in the hemophilic patients.</p>

Study on the efficacy and safety of Xueyou Mixture in treating hemophilia / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effect of Xueyou Mixture (, XYM) on blood coagulation factors and its safety in treating hemophilia.</p><p><b>METHODS</b>To the randomly selected 65 inpatients of hemophilia, XYM was administered accompanied with intravenous dripping of liver cell growth factor 60-100 mg once a day to protect the liver, with no blood products like concentrated VIII and FIX factors or blood plasma given. The treatment lasted for 3 weeks. The short-term efficacy and adverse reactions were observed. The long-term efficacy in patients was observed in a follow-up study of 6-12 months after they were discharged from the hospital but continuously took XYM orally.</p><p><b>RESULTS</b>The short-term markedly effective rate in the patients was 95.38% (62/65). After they were treated for 3 weeks, the level of FVIII factor activity increased in 56 patients of type A from (3.32+/-2.21) % to (4.18+/-2.23) %, and in 9 of type B from (4.92+/-1.81) % to (5.64+/-1.96) %. Compared with that before treatment, the difference was significant in both of them (P<0.01). No obvious adverse reaction was found in the treatment period. The follow-up study showed that in 22 patients of type A, the FVIII factor activity ratio increased from (3.25+/-2.11) % to (6.31+/-2.16) %, (8.36+/-1.05) %, and (16.38+/-2.71) % in the 2nd, 3rd and 6th month after discharge respectively, all showing significant difference to that before treatment (P<0.01); and in 4 patients of type B, it increased from (4.15+/-2.26) % to 7.8% and 11.6% (mean value) in the 2nd and 6th month respectively.</p><p><b>CONCLUSION</b>XYM could raise the activity of factors VIII and IX in patients with hemophilia, and the degree of the rise is related with the duration of the therapy, with no obvious adverse reaction, which strikes out a new path and new train of thinking for the treatment of the disease by nonblood preparation.</p>

Effect of realgar on expression of survivin in leukemia cell lines and its significance / 中国实验血液学杂志

To study the effect of realgar on expression of survivin in leukemia cell lines, HL-60 and Jurket cell lines were used as in vitro models. The expression of survivin was detected by Western blot analysis and immunofluorescence, and the expressions of Fas and caspase-3 were examined by immunohistochemistry. The results showed that the expression of survivin was positive in the two cell lines. HL-60 cells did not express Fas and caspase-3, and Jurket cells were Fas-positive and caspase-3 was negative. Realgar induced a dose- and time-dependent down-regulation of survivin expression in Jurket cells, and especially in HL-60. Caspase-3 expression changed from negative to positive in HL-60 cell, but there still was no expression in Jurket cell. It is concluded that survivin expression level decreased during leukemia cell apoptosis induced by Realgar. The down-regulation of survivin expression may be an important mechanism in leukemia cell apoptosis induced by realgar through mitochondrial pathway.
