Background: This study evaluates the efficacy of combined chemotherapy for the management of acute promyelocytic leukemia (APL). Method: Literature search was carried out in several electronic databases. Meta-analyses were performed to achieve weighted effect sizes of overall survival (OS), disease-free survival (DFS), complete remission (CR) rate, and relapse rate. Metaregression analyses were performed to evaluate the factors affecting CR and relapse rates. Results: Data from 37 studies (7566 patients) were used for meta-analysis. Median follow-up was 49.24 [95% confidence interval (CI): 41.33, 57.16] months. Five-year OS and DFS were 86.41 [83.97, 88.85] % and 75.42 [67.44, 83.40] %, respectively (pooled effect size [95% CI]). Following induction therapy, 89.77 [87.04, 92.50] % patients achieved CR in 38.25[37.84, 38.65] days and 6.34 [5.98, 6.70] % of the patients died during induction. Induction with all-trans retinoic acid (ATRA), arsenic trioxide (ATO), and daunorubicin (DNR) combination was associated with the highest rate of CR (96.16 [89.92, 92.40] %), followed by ATRA-DNR (94.29 [93.15, 95.43] %), ATRA-DNR-cytarabine (92.04 [88.38, 95.71] %), and ATRA-idarubicin (91.16 [89.92, 92.40] %). Overall relapse rate in the study population was 14.42 [11.97, 16.86] %. Baseline leukocyte count was inversely related to the CR rate. Conclusion: Combined chemotherapy for APL is associated with 90% CR, 14.4% relapse rate, 86% 5-year OS, and 75% 5-year DFS. Induction with ATRA-DNR-ATO is found better than other combinations with respect to CR and relapse rates.

Our study aimed to investigate the association between multidrug resistance (MDR1) gene polymorphisms and the response to imatinib (IM) in chronic myeloid leukemia (CML). An electronic databases in PubMed, Cochrane Library, Wanfang, China National Knowledge Infrastructure, and VIP were searched using combinations of keywords relating to MDR1 polymorphisms and the response to IM in CML. Studies retrieved from database searches were screened using stringent inclusion and exclusion criteria. The Comprehensive Meta-analysis 2.0 software was utilized for all statistical analyses. In total, 186 studies were initially retrieved, and 10 studies, involving 987 CML patients, were eventually included in this meta-analysis. Results of our study revealed no significant associations between MDR1 rs1045642, rs1128503, and rs2032582 polymorphisms and major molecular response and complete molecular response in CML patients. Significant differences were observed in the genotype frequencies of MDR1 rs1128503 under homozygous, heterozygous, and recessive models, between CML patients sensitive and resistant to IM. A significant difference in genotype frequencies of MDR1 rs2032582 was also observed under allele, homozygous, heterozygous, and recessive models between CML patients sensitive and resistant to IM. In conclusion, based on our meta-analysis, the MDR1 polymorphisms, rs1045642, rs1128503, and rs2032582, are not directly correlated with the curative effect of IM treatment of CML patients.

The aim of this meta-analysis was to investigate the overall diagnostic and prognostic values of CTHRC1 expression in human cancer development. Based on the inclusion and exclusion criteria, 8 cohort studies were included in the meta-analysis. The data were extracted, and analyses were performed using a random-effects model. Summary odds ratios (ORs) and effect sizes (ESs) with 95% confidence intervals (CIs) were calculated to assess the strength of the associations. A total of 1065 cancer patients from the 8 studies were included in the meta-analysis. The results revealed a positive correlation of CTHRC1 protein expression in tumors with tumor-node-metastasis (TNM) stage and with lymph node (LN) metastasis (TNM: OR = 2.98, 95%CI = 1.48-6.00, P = 0.002; LN: OR = 4.26, 95%CI = 1.88-9.67, P = 0.001). CTHRC1 expression was higher in tumors with sizes 5 cm than in tumors with sizes <5 cm (OR = 2.39, 95%CI = 1.12-5.09, P = 0.024). Patients with higher CTHRC1 expression had decreased overall survival (OS) (ES = 1.78, 95%CI = 1.23-2.33, P < 0.001) and poorer disease-free survival (DFS) (ES = 1.71, 95%CI = 1.11-2.31, P < 0.001). Disease-stratified analyses yielded significantly different estimates of CTHRC1 levels in the majority of the subgroups (all P < 0.05). In conclusion, increased CTHRC1 expression is associated with advanced TNM stage, increased LN metastasis and tumor size, and decreased OS and DFS, indicating that CTHRC1 may be a biomarker for prognosis of cancer patients.

Although 17-estradiol (E2) deficiency has been linked to the development of osteoarthritis (OA) in middle-aged women, there are few studies relating other estrogens and estrogen metabolites (EMs) to this condition. We developed a high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS) method to measure the levels of six EMs (i.e., estrone, E2, estriol, 2-hydroxyestrone, 2-hydroxyestradiol, and 16a-hydroxyestrone) in healthy pre- and postmenopausal women and women with OA. This method had a precision ranging from 1.1 to 3.1% and a detection limit ranging from 10 to 15 pg. Compared to healthy women, serum-free E2 was lower in the luteal and postmenopausal phases in women with OA, and total serum E2 was lower in postmenopausal women with OA. Moreover, compared to healthy women, total serum 2-hydroxyestradiol was higher in postmenopausal women with OA and total serum 2-hydroxyestrone was lower in both the luteal and follicular phases in women with OA. In conclusion, our HPLC-ESI-MS/MS method allowed the measurement of multiple biochemical targets in a single assay, and, given its increased cost-effectiveness, simplicity, and speed relative to previous methods, this method is suitable for clinical studies.

Background The aim of this study was to investigate the roles of MMP3 (matrix metalloproteinase-3) gene polymorphism and protein expression in deep venous thrombosis (DVT) among Chinese Han population. Methods A total of 280 subjects were included in this study and categorized as case group (144 DVT patients) and control group (136 healthy individuals). Polymerase chain reaction-restriction fragment length polymorphism was used to detect MMP3 promoter -1171 5A>6A genotype and allele frequencies. MMP3 serum levels were measured by enzyme-linked immunosorbent assay. SPSS version 18.0 statistical software was used for data analysis. Results There was significant difference in genotype frequencies of MMP3 gene -1171 5A>6A between the case group and the control group (all P < 0.05). Furthermore, the 6A allele on MMP3 -1171 5A>6A may be associated with increased risk of DVT (odds ratio 1.961, 95% confidence interval 1.309-2.939, P < 0.01). The MMP3 serum level in DVT patients was markedly higher than the control group (case group: 28.45 ± 10.97 vs. control group: 18.18 ± 9.03, P < 0.05). Serum MMP3 level in DVT patients carrying 5A/6A and 6A/6A genotypes was higher than the control group (P < 0.05). The bilateral calf circumference difference was significantly higher in DVT patients than the control group among all the genotypes at MMP3 gene -1171 5A>6A (all P < 0.05). Conclusion MMP3 gene -1171 5A>6A polymorphism and upregulated protein expression may be associated with DVT risk in Chinese Han population. © 2016 Elsevier Inc. All rights reserved.

Epilepsy is a common type of neurological disorder with complex etiology. The mechanisms are still not clear. MicroRNAs are endogenous noncoding RNAs with many physiological activities. Multiple microRNAs were abnormally expressed in status epilepticus, including miR-210. In this study, we applied lithium chloride and pilocarpine to induce epileptic activity and aimed to disclose the potential mechanisms. Our data showed that miR-210 was significantly upregulated in hippocampus one day after modeling (P<0.05 vs control) and the high expression of miR-210 lasted for at least 30 days. By contrast, y-aminobutyric acid (GABA) level significantly decreased concurrently after modeling (P<0.05 vs control). To question whether miR-210 could be a potential therapeutic target for epilepsy, miR-210 inhibitor was administrated through intrahippocampal injection after epilepsy modeling. Our data showed that morphological changes of hippocampal neurons and apoptosis triggered by epilepsy were mitigated by miR-210 inhibition. More importantly, the expressions of GABA-related proteins, including GABAA receptor a1, glutamate decarboxylase, and GABA transporter 1, were significantly elevated after epilepsy modeling in both mRNA and protein levels 3 days postmodeling (P<0.05 vs control), which were mitigated by miR-210 inhibitor treatment (P<0.05 vs model). In addition, epilepsy-induced upregulation of GABA transaminase was alleviated by miR-210 inhibitor. Taken together, these data implicated potential roles of miR-210 in lithium chloride-pilocarpine-induced epilepsy model and miR-210 could serve as a potential therapeutic target in status epilepticus. © 2016 Chen et al.

To investigate the effects of intranasal interferon gamma (IFN-γ) on nasal mucosa remodeling and expression of transforming growth factor-β1 (TGF-β1), Smad2, Smad3, Smad7 in allergic rhinitis (AR) rat model. Ovalbumin (OVA) and aluminum hydroxide were used to construct the AR model. Thirty AR rats were randomly divided into positive control group (group B, n = 10), IFN-γ treatment group (group C, n = 10) and negative control group (normal rats, n = 10). After the AR models were built, 50 μl PBS, 1 μg IFN-γ was dropped into the nasal cavity of each rat in group B and group C, from the fouth week to tenth week, twice a week. The nasal mucosa was collected on day 71 in order to observe the pathologic changes, and the expression of TGF-β1, TGF-β1 mRNA, Smad2 mRNA, Smad3 mRNA and Smad7 mRNA by immunohistochemistry and reverse transcriptase-polymerase chain reaction. Decreases of TGF-β1, Smad2 and Smad3 mRNA were seen in nasal tissue of group C (0.59 ± 0.04, 0.39 ± 0.08, 0.46 ± 0.15) as compared with group B (0.82 ± 0.12, 0.70 ± 0.18, 0.95 ± 0.26), the differences were significant (q value were 3.15, 4.47, 3.03, all P < 0.05). The levels of Smad7 mRNA expression increased significantly (q = 2.98, P < 0.05) in group C (0.31 ± 0.05) as compared with group B (0.25 ± 0.06). Immunohistochemistry showed significant decrease of TGF-β1 expression in the nasal tissue of group C much lesser than that in group B. Intranasal IFN-γ could decrease the expression of TGF-β1, TGF-β1 mRNA, Smad2 mRNA, Smad3 mRNA, increase the expression of Smad7 mRNA in AR rats model and inhibit the nasal mucosa remodeling.

To investigate the effects of sIL-5Rα and sIL-13Rα2 on VCAM-1 and IFN-γ in allergic rhinitis rats. A total of 50 Wistar rats were randomly divided into 5 groups: the normal group (group A), the allergic rhinitis model group (group B), the sIL-5Rα treatment group (group C), the sIL-13Rα2 treatment group (group D), the combination of sIL-5Rα and sIL-13Rα2 treatment group (group E or the combined treatment group). Rats in the latter 4 groups were sensitized with ovalbumin (OVA) and Al(OH)(3), and challenged with OVA to establish allergic rhinitis models, while rats in the normal group were treated with saline. Rats in the sIL-5Rα treatment group, the sIL-13Rα2 treatment group and the combined treatment group were absorbed on day 31 to day 38 once daily once nasal cavity with sIL-5Rα(100 μg), sIL-13Rα2 (100 μg) and the combination of sIL-5Rα (100 μg) and sIL-13Rα2 (100 μg) 30 min before challenged, while rats in the allergic rhinitis model group received PBS(50 μl). Then the levels of VCAM-1 and IFN-γ in serum and nasal lavage fluid (NLF) were measured by ELISA. Compared with the normal group, the levels of VCAM-1 in the allergic rhinitis model group were higher, while IFN-γ were lower (all P < 0.01). Compared with the allergic rhinitis model group, the sIL-5Rα treatment group, the sIL-13Rα2 treatment group and the combined treatment group could effectively reduced serum and NLF VCAM-1 level [group E: (283.5 ± 5.7) μg/L, (101.8 ± 4.8) μg/L; group C: (311.5 ± 12.6) μg/L, (133.9 ± 5.8) μg/L; group D: (304.7 ± 6.6) μg/L, (128.5 ± 7.7) μg/L], and increased IFN-γ level [group E: (874.7 ± 9.6) pg/ml, (349.2 ± 12.1) pg/ml; group C: (600.2 ± 16.1) pg/ml, (195.5 ± 16.1) pg/ml; group D: (577.9 ± 9.6) pg/ml, (196.7 ± 9.9) pg/ml ]; compared with single treatment, the combined treatment group also had significant differences(P < 0.01). Combined treatment with sIL-5Rα and sIL-13Rα2 to treat the allergic rhinitis rats can significantly reduce VCAM-1 levels in serum and NLF, and increase IFN-γ levels, thus, to achieve the purpose of mitigation and treatment of allergic rhinitis.
