Clinical Study on Prevention and Treatment of CIPN Induced by Vincristine Through TCM Prescription of Peripheral Neuropathy Hand-food Soaking Combined with Mecobalamin / 中国中医药信息杂志

Objective To observe the clinical efficacy of prevention and treatment of chemotherapy induced peripheral neurpathy (CIPN) by vincristine via using TCM prescription of peripheral neuropathy hand-food soaking combined with mecobalamin. Methods Totally 120 patients with non-Hodgkin's lymphoma who all received chemotherapy drugs including vincristine were randomly divided into treatment group (36 cases), control group (36 cases) and combined treatment group (36 cases). All groups received routine treatment (all used CHOP, R-CHOP and H-CAVD plans for the first time), for 6 cycles of chemotherapy. The control group was given mecobalamin at the same time, 0.5 mg each time, oral administration, three times a day. The treatment group was given TCM prescription of peripheral neuropathy hand-foot soaking at the same time, hands first and feet later, 20 minutes each time, twice a day. The combined treatment group was given TCM prescription of peripheral neuropathy and mecobalamin at the same time, the same as the former method. 7 days were set as one treatment course, and all the treatment lasted for 6 cycles of chemotherapy. The incidence and degree of CIPN were evaluated in 2, 4, and 6 cycles of chemotherapy, and the satisfaction was compared. 50 patients of CIPN degree ≥Ⅱ were screened, paused chemotherapy, and participated in consolidation treatment research. The 50 patients were assigned into treatment group (25 cases) and control group (25 cases). The control group took oral mecobalamin, and the treatment group used TCM prescription of peripheral neuropathy hand-foot soaking; the methods were the same as former methods, for 20 d. Clinical efficacy and satisfaction of both groups were evaluated. Results After the second cycle of chemotherapy, the incidence of CIPN in the treatment group and the combined treatment group were obviously lower than the control group (P<0.05). After the fourth cycle of chemotherapy, the incidence of CIPN in the combined treatment group were obviously lower than the control group (P<0.01); the incidence of CIPN degree ≥Ⅱ in the treatment group and combined treatment group were obviously lower than the control group (P<0.05). After the sixth cycle of chemotherapy, the incidence of CIPN degree ≥Ⅱ in the treatment group and combined treatment group were obviously lower than the control group (P<0.01). The satisfaction rate of the treatment group was higher than the control group (P<0.01). For the consolidation therapy to patients of CIPN degree ≥Ⅱ, there was no statistical significance in clinical efficacy between the treatment group and the control group (P>0.05), but the satisfaction rate of the treatment group was higher than the control group (P<0.01). Conclusion TCM prescription of peripheral neuropathy hand-food soaking combined with mecobalamin can obviously relieve CIPN degree induced by vincristine, and improve the life quality of patients.

Detection of microvesicle miRNA expression in ALL subtypes and analysis of their functional roles / 华中科技大学学报（医学）（英德文版）

Microvesicles (MVs) are the heterogeneous mixtures of vesicles. MVs released by leukemia cells constitute an important part of the leukemia microenvironment. MVs might act as important reservoirs of microRNAs (miRNAs). It is worth evaluating whether MVs possess some unique miRNA contents that are valuable in understanding the pathogenesis. In this study, we investigated the miRNA expression patterns of Nalm-6-derived MVs, Jurkat-derived MVs and normal cell-derived MVs using miRNA microarrays. The potential target genes regulated by differentially expressed miRNAs were also predicted and analyzed. Results demonstrated that 182 miRNAs and 166 miRNAs were differentially expressed in Nalm-6-MVs and Jurkat-MVs, respectively. Many oncogenes, tumor suppressors and signal pathway genes were targeted by these aberrantly expressed miRNAs, which might contribute to the development of B-ALL or T-ALL. Our findings expanded the potential diagnostic markers of ALL and provided useful information for ALL pathogenesis.

Pregnancy outcomes and risk factors for low birth weight and preterm delivery among HIV-infected pregnant women in Guangxi, China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Six provinces in China accounted for 70% - 80% of all reported HIV/AIDS cases in the country in 2009 and five provinces accounted for 78% of all reported mother-to-child transmission (MTCT) of HIV cases. Because Guangxi belonged to both groups, the Prevention of Mother-to-Child Transmission (PMTCT) Plus program was established there to understand better low birth weight (LBW) and preterm delivery (PD) birth outcomes and their associated risk factors better.</p><p><b>METHODS</b>Pregnancy outcomes were examined among HIV-infected pregnant women who enrolled in the PMTCT Plus program from June 2006 to February 2009 in Guangxi, China. Multivariate Logistic regression analysis was used to explore the risk factors associated with LBW (< 2500 g) and PD (gestational age < 37 weeks).</p><p><b>RESULTS</b>The prevalence of LBW and PD among 194 HIV-positive mothers was 19.6% (38/194) and 9.8% (19/194), respectively. Multivariate Logistic regression analysis showed that CD4 cell count < 100 cell/µl (multivariate-adjusted odds ratio (AOR) 5.52; 95%CI 1.11 - 25.55) and CD4 cell count 100 - 199 cells/µl (AOR 3.40; 95%CI 1.03 - 11.25, compared to CD4 cell count ≥ 350 cells/µl), gestational age < 37 weeks (AOR 4.38; 95%CI 1.29 - 14.82, compared to ≥ 37 weeks), maternal weight < 45 kg (AOR 5.64; 95%CI 1.09 - 29.07) and maternal weight 45 - 54 kg (AOR 3.55; 95%CI 1.31 - 9.60, compared to ≥ 55 kg) at enrollment, and HIV RNA ≥ 100 000 copies/ml at enrollment (AOR 4.22; 95%CI 1.24 - 14.32) and 20 000 - 99 999 (AOR 2.77; 95%CI 1.01 - 7.77, compared to < 20 000 copies/ml) were associated with a higher risk of LBW. For PD, only maternal injection drug use as the route of HIV transmission (AOR 5.30; 95%CI 1.33 - 21.14, compared to those infected with HIV through sexual transmission) was significantly associated with a higher risk of PD.</p><p><b>CONCLUSIONS</b>Lower CD4 cell count and higher HIV RNA viral load at enrollment were associated with LBW. Optimal antenatal care, including earlier antenatal screening and HIV diagnosis, is critical to earlier PMTCT prophylaxis and/or HIV treatment to prevent transmission of HIV to the infant and also to prevent LBW pregnancy outcomes.</p>

The CXC-chemokine platelet factor 4 (PF4) increases KG1a cells adherence and modulates actin polymerization of KG1a cells / 中国医学科学院学报

<p><b>OBJECTIVE</b>To study the effects on adherence of hematopoietic stem/progenitor cells, PF4 was assessed alone or in combination with IL-3 for effects on the total adherence and various kinds of adhesion molecules of KG1a cells as well as actin polymerization in KG1a cells.</p><p><b>METHODS</b>The total adherence was assayed by crystal violet dye staining. The adhesion molecule expression was determined by FACS analysis. These adhesion molecule monoclonal antibodies individually blocked total adherence by MTT. F-actin content was monitored by fluorospectrophotometry.</p><p><b>RESULTS</b>100 ng/ml PF4 could increase the total adherence of KG1a cells by 80%. 20 ng/ml IL-3 could increase the total adherence of KG1a cells by 96%. When PF4 and IL-3 were combined, the total adherence could be promoted by 97%. Exposure of 1 x 10(6) cells/ml of KG1a cells to 100 ng/ml PF4 the increased total adherence of KG1a cells was mediated by PECAM-1 (CD31), CD44, LFA-1 (CD11a) and Mac-1 (CD11b) but not by P-selectin (CD62P) and E-selectin (CD62E). These adhesion molecule monoclonal antibodies could individually block total adherence for 34%-43%. Similar phenomenon was observed when IL-3 was added onto KG1a cells. Further study found that PF4 induced actin polymerization of KG1a cells.</p><p><b>CONCLUSIONS</b>Our study indicated that PF4 promoted total adherence, as well as several adhesion molecule expression and actin polymerization of KG1a cells. The results suggest that PF4 may have therapeutic utility along with other cytokines by enhancing the total adhesion of hematopoietic stem/progenitor cells to promote the homing.</p>
