Systematic review and Meta-analysis of efficacy and safety of Huachansu in treating cancer-related pain / 中国中药杂志

To evaluate the effectiveness and safety of Huachansu in the treatment of cancer-related pain,four Chinese databases( CNKI,VIP,Wan Fang,Sino Med) and three English databases( Cochrane Library,Medline,PubMed) were systematically and comprehensively retrieved since the establishment of each database to October 2018. Randomized controlled trials( RCTs) for the treatment of cancer-related pain with Huachansu were screened out according to pre-established inclusion criteria and exclusion criteria. Rev Man5. 3 software was used for Meta-analysis. A total of 241 articles were retrieved,and finally 10 studies were included. The total sample size was 1 293,including 648 in the experimental group and 645 in the control group. The overall quality of the included studies was generally low. The results of Meta-analysis showed that Huachansu combined with Western medicine acesodynes was superior to the single use of Western medicine acesodynes in the treatment of short-term pain relief,improvement of quality of life and reduction of constipation,nausea and vomiting,dizziness,drowsiness,anorexia and other adverse reactions. And it also has the advantage of a shorter onset time and longer duration time of analgesia,but cannot reduce the incidence of dysuria. Based on the findings,Huachansu had a certain effect in the treatment of cancer-related pain,and a significant positive effect on the improvement of quality of life and the reduction of adverse reactions. No serious adverse reactions occurred. However,due to the small number of studies included,the low quality of the included studies,published biases and other restrictions,the evidence in this study has a low quality,and the conclusion shall be adopted with caution. The effectiveness and safety of Huachansu in the treatment of cancer-related pain remained to be further confirmed in the future with a well-designed,rigorous,and standardized report,with a large sample size,multiple centers,and sufficient follow-up time for randomized controlled trials.

<p><b>OBJECTIVE</b>To observe the effects of Compound Zhebei Granule (, CZBG) combined with chemotherapy on surface markers of leukemia stem cell (LSC) in the bone marrow of patients with acute myeloid leukemia (AML).</p><p><b>METHODS</b>Seventy-eight patients with AML received bone marrow aspiration and the percentages of CD34(+) CD123(+) and CD33(+) CD123(+) cells were tested using flow cytometry method. A total of 24 refractory or relapsed AML patients were enrolled and treated with one cycle of standard chemotherapy combined with CZBG. Bone marrow samples were obtained before and after treatment, and the percentages of CD34(+) CD123(+) and CD33(+) CD123(+) cells were examined by flflow cytometry.</p><p><b>RESULTS</b>Compared with refractory or relapsed AML patients, patients achieved remission had a significant lower percentage of CD34(+) CD123(+) cells(P<0.01) and CD33(+) CD123(+) cells (P<0.01), indicating that controlling the LSC percentage may be important for patients with AML to achieve sustainable remission. Compared with those before treatment, the expression levels of CD34(+) CD123(+) were significantly decreased after CZBG combined with chemotherapy treatment (P<0.01). The percentages of CD34(+) CD123(+) cells and CD33(+) CD123(+) in patients achieving complete remission after CZBG combined with chemotherapy treatment were both significantly lower than those in patients with nonremission (P<0.01).</p><p><b>CONCLUSION</b>CZBG combining chemotherapy could reduce the percentages of CD34(+) CD123(+) and CD33(+) CD123(+) LSC, which might improve the clinical efficacy of refractory or relapsed AML.</p>

Expression of biomarkers related with bone marrow cells in patients with acute myelogenous leukemia / 中国实验血液学杂志

This study was aimed to investigate the expression of biomarkers (PTEN, mTOR, NF-kB, CD44, PI3K) related with bone marrow cells in patients with acute myelogenous leukemia. The immunohistochemical method was used to detect the expression of PTEN, mTOR, NF-kB, CD44, PI3K in 20 patients. The AML patients were divided into remission group and non-remission group after calculating the percentage of leukemia cells in bone marrow. The results showed that by optical microscopy, the positive expression rates of PTEN, mTOR, NF-kB, CD44 and PI3K in remission group were 33.3%, 33.3%, 77.8%, 22.2%, 0, respectively; meanwhile, in non-remission group, the positive expression rates of above-menthioned biomarkers were 63.6%, 18.2, 90.9, 63.6%, 0, respectively. The percentage and mean OD for PTEN and CD44 were statistically different between the two groups (P < 0.05), but for mTOR, NF-kB and PI3K were not statistically differenly (P > 0.05). It is concluded that the high expression of PTEN and CD44 can be regarded as an important index for diagnosis and prognosis in acute myelogenous leukemia.

Mesenchymal stem cells release membrane microparticles in the process of apoptosis / 中国实验血液学杂志

Though mesenchymal stem cells (MSC) have been clinically used to repair a variety of damaged tissues, the underlying mechanisms remain elusively as the majority of the ex vivo expanded MSC die shortly after transplantation. To explore the mechanism in which the death cells play tissue repair effect, apoptosis of rat bone marrow MSC was induced by culturing cells in the conditions of hypoxia or/and serum-free medium, and the subcellular structures in the supernatants were analyzed. The results showed that apoptosis occurred in the presence of either hypoxia or serum-free condition as well, and the apoptotic proportion reached up to (17.44 ± 2.15) after the cells were treated by hypoxia plus serum free culture for 72 hours. The flow cytometric analysis of the sub-cellular substances harvested by ultracentrifugation of the supernatants found that the MSC released substantial amount of membrane microparticles into the supernatants, which expressed CD29, CD44A and Annexin-V-binding phosphatidylserine. It is concluded that the MSC can release membrane microparticles after induction, the amount of these membrane microparticles was around 15-fold of the parent cell numbers. The membrane microparticles is the mediators in the cross-talk between the transplanted cells and their surrounding tissues. This study provides some novel information for the mechanisms of MSC therapy.

Effect of compound Zhe-Bei granule (CZBG) combined with doxorubicin on cell apoptosis and expression of related proteins in K562/A02 multidrug resistance tumor xenografts in mice / 中国实验血液学杂志

This study was purposed to investigate the effects of compound Zhe-Bei granule (CZBG) combined with doxorubicin (Dox) on the expression of BCL-2, BAX and cell apoptosis rate in K562/A02 multidrug resistant tumor xenografts. Tumor xenograft model was established by injecting the K562/A02 cells into the axillary flank of BALB/c nude mice. The cell apoptosis rate of xenografts was detected by flow cytometry with Annexin V-FITC/PI staining. The expressions of BCL-2 and BAX in xenografts were measured by immunohistochemistry staining. The value of integral optical density (IOD) was calculated according to staining image on slide. The results indicated that as compared with normal saline control group and Dox group, the high, middle, low dose of CZBG combined with Dox could increase the cell apoptosis rate of tumor xenografts with statistical significance (p < 0.05); and could decrease the IOD value of BCL-2 and increase the IOD value of BAX in xenografts with statistical significance (p < 0.05). It is concluded that CZBG combined with Dox can enhance the apoptosis rate in K562/A02 cells, down-regulate the expression of BCL-2 and up-regulate the expression of BAX, thereby, can reverse the multidrug resistance of K562/A02 cells by decreasing the ratio of BCL-2/BAX.
