OBJECTIVETo analyze the therapeutic effect and the influencing factors of event-free survival (EFS) of childhood acute lymphoblastic leukemia (ALL) in Xiangya Hospital of Central South University and the First Affiliated Hospital of Guangxi Medical University.

METHODSAll the patients adopted chemotherapy according to therapeutic guideline revised by the Subspecialty Group of Hematology, The Society of Pediatrics, Chinese Medical Association for the second-time in 1998 (the Rongcheng ALL-98 Protocol). Kaplan-Meier method was used to estimate the survival rates of 188 patients who received therapy with good compliance. The differences of EFS between groups were assessed by Log-rank test. The independent influencing factors on EFS were analyzed by the Cox proportional hazards regression model.

RESULTSAfter receiving inductive treatment, 354 of 374 (93.6%) patients demonstrated a complete remission; 188 patients who received complete courses of treatment with good compliance showed (68.1 +/- 5.6)% five-year EFS. Meanwhile, the five-year EFS in standard-risk (SR) group and high-risk (HR) group were (75.2 +/- 6.0)% and (47.6 +/- 11.6)%, respectively. The total relapse rate was 10.6% and the median time to relapse was 13 months. Twenty-nine of 188 patients (15.4%) were dead, and 13 patients (7.0%) died from treatment-related complications. Independent adverse prognostic factors included risk grouping, t (9; 22)/bcr-abl gene and leukocyte count.

CONCLUSIONSThe total EFS of childhood ALL patients treated with Rongcheng ALL-98 Protocol in two hospitals was close to 70%. Therefore, it is necessary to evaluate risk factors and consider the grouping in more detail to reduce the treatment-related mortality and to increase the compliance of treatment which can ultimately improve the EFS.

Objective To systematically review the effects of intracoronary microcatheter agents in the treatment of patients with no-refl ow phenomenon. Methods Databases including Medline, EMbase, the Cochrane Library, CBM, CNKI, VIP and WanFang Data were searched electronically f rom inception to April 2017 for randomized controlled trials (RCTs) about intracoronary agents for no-reflow phenomenon. Two reviewers independently screened literatures, extracted data and assessed the risk of bias of the studies included. Meta-analysis was then performed using RevMan 5.3 software. Results A total of 8 RCTs involving 424 patients were included. The results of Meta-analysis showed that the microcatheter group had significantly better TIMI flow grade[RR=0.38,95%CI(0.27,0.52), P<0.000 01],TIMI myocardial perf usion grade[RR=0.35,95%CI(0.23,0.55),P<0.000 01],corrected TIMI f rame count[MD=-9.99,95%CI(-13.22,-6.76)P<0.000 01]and hypotension[RR=0.57,95%CI(0.35, 0.90),P=0.02] than those of the guiding catheter group. There was no statistical difference between the two groups in short period major adverse cardiovascular events and left ventricular ejection fraction.Conclusions Current evidence shows that intracoronary microcatheter agents could improve blood flow in patients with no-reflow phenomenon and has good safety. Due to the limited quantity and quality of the included studies, the above conclusion still needs to be verified by carrying out more high-quality RCTs.

To systematically review the adjuvant effects of Zhenyuan capsule on improving the cardiac function of patients with chronic heart failure. Databases including PubMed, EMbase, the Cochrane Library, CBM, CNKI, VIP and Wanfang Data were searched electronically from inception to October 2016 to collect randomized controlled trials (RCTs) about Zhenyuan capsule for adjuvant treatment of chronic heart failure. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, Meta-analysis was performed by using RevMan 5.3 software. A total of 14 RCTs involving 1 204 patients were included. The results of Meta-analysis showed that the Zhenyuan capsule group had significantly better effectiveness in cardiac function (RR=1.27, 95%CI 1.20 to 1.35, P < 0.000 01), stroke volume (WMD=7.62, 95%CI 6.39 to 8.84,P < 0.000 01), scores of HAMA (WMD=-4.16, 95%CI -5.59 to -2.72, P < 0.000 01), psychological effect of HAMA (RR=1.47, 95%CI 1.15 to 1.89, P=0.002), and traditional Chinese medical syndrome (RR=1.46, 95%CI 1.25 to 1.72, P < 0.000 01) than those of the control group, with statistically significant differences. Current evidence showed that Zhenyuan capsule combined with routine treatment could improve the cardiac function and quality of life of patients with chronic heart failure, and with high safety. Due to the limited quantity and quality of the included studies, the above conclusion still needs to be verified by carrying out more high-quality RCTs.

Objective: To investigate the relationship between plasma level of pro-protein convertase subtilisin kexin type9 (PCSK9) and coronary artery calcification (CAC). Methods: A total of 380 consecutive chest pain patients without lipid-lowering therapy were enrolled. All patients received CT scan and coronary artery calcification (CAC) score measurement and were divided into 2 groups: CAC group, n=156 patients with CAC score>0 and Non-CAC group, n=224 patients with CAC score=0. CAC group was further classified in 3 subgroups as CAC score (1-100) subgroup, n=53, CAC score (101-400) subgroup, n=64 and CAC score>400 subgroup, n=39. Clinical data was collected, plasma levels of PCSK9 were measured in all patients and the relationship between PCSK9 and CAC score was investigated. Results: Plasma PCSK9 level in CAC group was higher than Non-CAC group (260.23±69.34) ng/ml vs (205.46±53.21) ng/ml, P<0.001; alone with CAC score increasing, PCSK9 level was elevating accordingly as in CAC score (1-100) subgroup, CAC score (101-400) subgroup and CAC score>400 subgroup, PCSK9 levels were (247.38±72.68) ng/ml, (264.87±57.63) ng/ml and (295.33±69.06) ng/ml respectively, all P<0.05. With adjusted traditional cardiovascular risk factors, multivariate regression analysis confirmed that plasma PCSK9 level was independently related to CAC score (β=0.584, P=0.002). In addition, the optimal cut-off value for PCSK9 predicting CAC was 228.58 ng/ml with sensitivity at 67% and specificity at 71%. Conclusion: Plasma PCSK9 level was related to CAC in chest pain patients without lipid-lowering therapy.

OBJECTIVE: To investigate the effects of myeloid differentiation-2 (MD2) gene silencing on high glucose-induced proliferation inhibition, apoptosis and inflammation in rat cardiomyocytes. METHODS: The immortalized rat cardiomyocyte cell line H9C2 were transfected with MD2 small interfering RNA (si-MD2) and negative control for 24 h, then stimulated with high glucose (HG) for 48 h. RT-qPCR was performed to detect the mRNA levels of MD2 and inflammatory factors TNF-α, IL-1β and IL-6. MTS and flow cytometry were used to evaluate cell proliferation, cell cycle and apoptosis rate. Western blot was used to detect protein expression levels and phosphorylation levels. RESULTS: The mRNA and protein levels of MD2 in H9C2 cells were dramatically decreased after transfected with si-MD2 (P＜0.01). After stimulation of high glucose, the mRNA levels of inflammatory factors, the cells in G0/G1 phase , the cell apoptosis rate and the protein level of cleaved Caspase-3 were significantly increased, while the cell proliferation ability was decreased (P＜0.01). MD2 gene silencing antagonized the effects of high glucose on cell proliferation, cell cycle, cell apoptosis and the mRNA levels of TNF-α, IL-1β , IL-6(P＜0.05). Western blot analysis showed that the phosphorylation levels of extracellular signal-regulated kinase(ERK1/2), P38 mitogen-activated protein kinase(P38 MAPK) and C-Jun N-terminal kinase(JNK) protein were increased significantly in H9C2 cells treated with high glucose, which could be reversed by silencing of MD2 (P＜0.01). CONCLUSION This study demonstrates that MD2 gene silencing reverses high glucose-induced myocardial inflammation, apoptosis and proliferation inhibition via the mechanisms involving suppression of ERK, P38 MAPK, JNK signaling pathway.

ObjectiveTo explore the effects and possible actions mechanisms of β-sitosterol on the proliferation of hepatocellular carcinoma （HCC） cells. MethodsThe target of β-sitosterol was predicted by SwissTarget and TargetNet data platforms. The up-regulated gene in GSE101728 HCC data set was analyzed by GEO2R， and the common gene between the target and the up-regulated gene was analyzed. According to the analysis of TCGA_LIHC data matrix， the relationship between cell division cyclin 25B （CDC25B） and clinical staging， prognosis of HCC was obtained. The activities， proliferation， cycles distribution and apoptosis of HCC cells （HepG2， Hep3B） treated with β-sitosterol were detected by CCK-8， colony-forming assay and flow cytometry. The models of nude mice with subcutaneous xenografted tumors in HepG2 were constructed and divided into control group and β-sitosterol group. The β-sitosterol group was intraperitoneally injected with β-sitosterol （50 mg/kg·d）. The volume and mass of tumors were measured. The expression level of Ki67 was detected by immunohistochemistry. The levels of CDC25B protein in HepG2 and Hep3B cell lines treated with different concentrations of β-sitosterol for different action time were detected by Western blot. HepG2 and Hep3B cell lines with stable overexpression of CDC25B were constructed， and then which were treated with β-sitosterol. The activities， proliferation， cycles distribution and apoptosis of HepG2 and Hep3B cell lines were detected by the above-mentioned methods. ResultsThe expression level of CDC25B in HCC tissues was higher than that in para-carcinoma tissues （P<0.05）. The expression level of CDC25B in patients with TNM staging at stage T2-4， clinical staging at stage Ⅱ-Ⅳ， G3-4 differentiation， recurrence and poor prognosis was higher than that with TNM staging at stage T1， clinical staging at stage I， G1-2 differentiation， non-recurrence and good prognosis， respectively （P<0.05）. The overall survival rate in high-expression CDC25B group was lower than that in low-expression group （P<0.05）. The activities of Hep3B and HepG2 cells were decreased with the increase of β-sitosterol dose and the prolongation of action time. The relative number of clone cells and the percentages of cells during S phase in Hep3B （15 μmol/L β-sitosterol） and HepG2 （18 μmol/L β-sitosterol） were significantly lower than those in control group （P<0.05）， while percentage of cells during G0/G1 phase and apoptosis rate were significantly higher than those in control group （P<0.05）. The volume and mass of xenografted tumors， and relative expression level of Ki67 in β-sitosterol group were significantly lower than those in the control group （P<0.05）. The expression of CDC25B protein in Hep3B and HepG2 cells was decreased with the increase of β-sitosterol concentration and the prolongation of action time. The cells growth， relative number of clone cells， and percentages of cells during S phase in Hep3B and HepG2 cells were all significantly higher than those in β-sitosterol group （P<0.05）， while percentage of cells during G0/G1 phase and apoptosis rate were significantly lower than those in β-sitosterol group （P<0.05）. ConclusionThe β-sitosterol can promote apoptosis of HCC cells and inhibited their proliferation. The inhibition of cells proliferation may be related to inhibition of CDC25B protein.

Wu-tou decoction (WTD) was originally recorded in the synopsis of the golden chamber and it had been widely used for the treatment of neuropathic pain (NP) with exact therapeutic efficacy. However, the underlying molecular mechanisms still remain unclarified. Thus, in this research, we aimed at clarifying the underlying molecular mechanisms of WTD against NP by combining network analysis and experimental validation based on the spinal nerve ligation (SNL) model. Firstly, the network analysis indicated that key targets of WTD were significantly involved in the MAPK signaling pathway (P = 4.04E-12) and four important components of the above pathway, AKT kinase (AKT), MAP kinase kinase 4 (MKK4), c-Jun N-terminal kinase (JNK) and transcription factor AP-1 (JUN) had been reported to play a vital role in neuroinflammation during the disease process of NP. Then, experimental validation results proved that WTD markedly reduce the severity of mechanical allodynia (P<0.01) and cold hypersensitivity (P<0.05) of SNL rats. In addition, Western blot results provided evidence that the phosphorylated protein expression levels of AKT, MKK4, JNK and JUN in the superficial lamina of spinal cord of SNL rats were markedly increased (P<0.001), and WTD could improve the phosphorylated protein expression level of AKT (P<0.001) which was reported to be nerve protective and attenuate the phosphorylated protein expression levels of MKK4, JNK and JUN (P<0.01) which were closely involved into neuroinflammation. In conclusion, this study indicated that WTD might exert anti-hyperalgesia action through the inhibition of neuroinflammation mediated by AKT-MKK4-JNK-JUN which belong to the MAPK signaling pathway. These findings also provided scientific evidences that WTD might be a promising candidate for NP. Animal experiments in this study were approved by the Ethics Committee of Experimental Animals of the China Academy of Chinese Medical Sciences.
