ABSTRACT

OBJECTIVE@#To evaluate the efficacy of decitabine combined with low-dose CEG regimen (DCEG) and decitabine combined with low-dose CAG regimen (DCAG) in the treatment of elderly patients with MDS and MDS-transformed acute myeloid leukemia (AML).@*METHODS@#A prospective study was conducted in 7 medical centers, 45 patients with MDS (≥ 60 years old) and MDS-transformed AML from October 2016 to January 2019 were enrolled, with the median age of 68.5 years old. The risk stratification of patients was poor or very poor, according to IPSS-R score. The treament results of decitabine combined with CEG and decitabine combined with CAG were compared.@*RESULTS@#The comparison of the two regiem showed that the DCEG regimen had advantages on total effective rate (ORR, 86.4% vs 47.8%, respectively), overall survival time (OS) (10.0 months vs 6.0 months, respectively) and progression-free survival time (PFS) (9.0 months vs 3.0 months, respectively). About 50% of MDS patients treated by DCEG regimen achieved PR or CR, with a median OS of 31 months. Multivariate analysis showed that patients with PR or CR after induction therapy and DCEG regimen had longer survival time (31months). The incidence of bone marrow suppression, infection and treatment-related mortality rate were similar between the two groups.@*CONCLUSION@#Decitabine combined with CEG regimen could improve the survival of patients with high-risk MDS and MDS-transformed AML. The conclusion of the reaserch needs to be validated by a larger prospective randomized clinical trial.

ABSTRACT

The genus Orobanche, Cistanche and Boschniakia are taxonomically classified as members of Orobanchaceae. The medicinal plants of these three genera are closely related, and their traditional curative effects are similar. As representative compounds, phenethyl glycosides are predominantly dominant type both in amount and in chemical structural varieties, which are considered to be the important bioactive material basis of these genera. In this paper, phenethyl glycosides and their pharmacological activities are described in a single list. In addition, the other compounds were also reviewed in order to better compare the difference of the bioactive substances. These findings have important reference value for effective development and rational utilization of resources of medicinal plants in the family Orobanchaceae.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the therapeutic effect of Yishen Qufeng Shengshi Recipe (, YQSR) in patients with glomerular proteinuria METHODS: A total of 145 patients with glomerular proteinuria were selected and randomly assigned to the treatment group (108 cases) and the control group (37 cases) according to a random number table in a ratio of 3:1. All patients received conventional and symptomatic treatment. In addition, patients in the treatment and control groups were given YQSR (200 mL, twice per day, orally) and losartan (50 mg/d orally), respectively for 6 months. The 24-h urine protein quantity, blood urea nitrogen, and serum creatinine in the two groups were measured at multiple time points before and after treatment.</p><p><b>RESULTS</b>At the end of the study, 5 cases were lost to follow-up in the treatment group and 1 in the control group. Finally, the statistical data included 103 cases in the treatment group and 36 cases in the control group. The total effectiveness after 2, 4, and 6 months was 81.6% (84/103), 87.4% (90/103), and 92.2% (95/103), respectively, in the treatment group and 47.2% (17/36), 55.6% (20/36), and 61.1% (22/36), respectively, in the control group, with significant difference between the two groups (P<0.01 at all observation points). In the treatment group, the curative effect after 6 months was better than that after 2 months (P<0.05). The 24-h urine protein quantity was significantly lower in the treatment group at 3, 4, 5, and 6 months than that in the control group (P<0.05 or P<0.01, respectively) CONCLUSION: YQSR could significantly reduce the amount of glomerular proteinuria in the early stage.</p>

ABSTRACT

To explore the network pharmacological mechanisms of four anti-vitiligo Uyghur medicines based on the Phlegmatic temperament theory. First, The anti-vitiligo Uyghur medicine formulas based on Phlegmatic temperament theory were collected. The pharmacokinetic characteristic of main compounds in four anti-vitiligo Uyghur medicines were obtained by using admetSAR. The targets of active compounds were predicted via bSDTNBI (balanced substructure-drug-target network-based inference model) method. Then, biological process (BP) and molecular function (MF) enrichment analysis of targets were analysed via DAVID database. Constructing anti-vitiligo Uyghur medicine formula-Uyghur medicines network model (FMI network) and Uyghur medicines-active compounds-targets-BP-Hilit network model (MCTBHI network), we utilized closeness centrality to analyse key Uyghur medicines, active compounds, key targets as well as Hilit. Finally, the in vitro melanin production model of C57BL/6 mice was used to verify the ability of the active compounds to improve melanogenesis. The results showed that Psoralea corylifolia, Vernonia anthelmintica, Syzygium aromaticum and Anacyclus pyrethrum were the key Uyghur medicines in the FMI network. There were 22 active compounds with a relatively higher bioavailability interacted with 58 therapeutic targets. These active compounds were mainly composed of coumarins and flavonoids. In the MCTBHI network, the MF of 58 therapeutic targets was related to steroid hormone receptor activity, heme binding and enzyme binding functhon. Classification of the Hilit according to the BP of 58 therapeutic targets, the first place was the blood, followed by the lymph, the cerebrospinal fluid and digestive juice. It was found that the expression of some targets located in the skin was closed to the heart muscle, lymph node, spleen, cerebral cortex and so on, which were the main places for Hilit. In particular, ESR1, PTGS2, PPARA, PPARG, PTGS1 and CA2 were regulated by the flavonoids (kaempferide and isorhamnetin). The in vitro melanin production model showed that kaempferide and isorhamnetin could promote the melanin production in C57BL/6 mice ear skin. Based on admetSAR and bSDTNBI, we used network pharmacological method to construct a systematic means of studying anti-vitiligo Uyghur medicines, providing clues for the further study of the modern molecular mechanisms of Phlegmatic temperament.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of chitinase 3-like 1 (CHI3L1) alone or in combination with other biomarkers in the diagnosis of pancreatic cancer.</p><p><b>METHODS</b>Serum samples were collected from 70 patients with pancreatic cancer and 31 healthy subjects and the levels of CHI3L1, CA199, C3, C4, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein-cholesterol (LDL-C) in serum were detected.</p><p><b>RESULTS</b>The serum samples from pancreatic cancer patients showed significantly higher CHI3L1, CA199, C3, C4, HDL-C, and LDL-C levels than those from healthy subjects (P<0.05). In patients with pancreatic cancer, serum CHI3L1 level was significantly correlated with the administration of anti-cancer therapy (P<0.05), but not with gender, age, metastasis or other clinicopathological parameters (P<0.05). ROC curve analysis showed that serum CHI3L1, CA199, C3, C4, HDL-C, and LDL-C all had diagnostic value for pancreatic cancer. Multivariate analysis suggested that the combined detection model of CHI3L1, CA199, C3, and HDL-C (AUC=0.964) had a greater diagnostic value than CA199 (AUC=0.896) alone and the combined detection model consisting of CA199, C3, and HDL-C (AUC=0.923; P<0.05).</p><p><b>CONCLUSION</b>Serum levels of CHI3L1, CA199, C3, C4, HDL-C, and LDL-C all have diagnostic value for pancreatic cancer, and the combined model consisting of CHI3L1, CA199, C3, and HDL-C have greater diagnostic efficacy than the other biomarkers either alone or in combination.</p>

ABSTRACT

To evaluate the clinical efficacy and safety of tripterygium glycosides (TG) in the treatment of henoch-schonlein purpura nephritis(HSPN). Seven English and Chinese databases (up to Nov. 9, 2017), were searched to collect the RCTs on TG for HSPN. Two researchers independently screened the literature according to inclusion criteria and exclusion criteria, extracted data, and evaluated the quality of the literature. After completion, cross-checking was performed and Meta-analysis was performed using RevMan 5.3 software. At the same time, different outcomes of the interventions were analyzed subgroupically. A total of 46 RCTs were included, with 1 659 in the experimental group and 1 596 in the control group. All the clinical studies showed a low quality. In terms of complete remission rate, the group with TG performed better than the group with conventional therapy or GC(RR=1.82,95%CI[1.39,2.39];RR=2.03,95%CI[1.37,2.99]),the group with TG+GC performed better than the group with GC(RR=1.46,95%CI[1.32,1.60]),and the group with CTX+GC performed better than the group with TG+GC(RR=0.35,95%CI[0.16,0.75]). In terms of total effective rate, the group with TG performed better than the group with conventional therapy or GC(RR=1.44,95%CI[1.19,1.74];RR=1.30,95%CI[1.16,1.46]),the group with TG+GC performed better than the group with GC(RR=1.27,95%CI[1.21,1.34]),and the group with CTX+GC performed better than the group with TG+GC(RR=0.60,95%CI[0.43,0.85]). No significant difference was found between the group with TG+GC and LEF+GC(RR=0.68,95%CI[0.30,1.53]). In terms of urinary protein, urine occult blood negative time,the group with TG performed better than the group with conventional therapy(MD=-9.00,95% CI[-11.99,-6.01];MD=-12.00,95%CI[-16.13,-7.87]),the group with TG+GC performed better than the group with GC(MD=-8.86,95%CI[-10.08,-7.64];MD=-16.24,95%CI[-23.80,-8.67]). In terms of recurrence rate, the group with TG+GC was lower than the group with GC(RR=0.13,95%CI[0.06,0.25]), but there were no significant difference between the group with TG and conventional therapy(RR=0.43,95%CI[0.15,1.19]). In adverse reactions, the common adverse effects of TG were gastrointestinal discomfort, liver damage and leucopenia. TG for the treatment of HSPN can improve clinical efficacy, reduce recurrence, and the adverse reactions are relatively safe. Due to the generally low methodological quality of the included studies, which affected the accuracy and reliability of the result. Therefore, more high-quality, large samples and multi-center randomized controlled trials are necessary for further evidence.

ABSTRACT

AIM: To evaluate the safety and efficacy of Ahmed glaucoma valve implantation for refractory glaucoma after sequential failed trabeculectomy. METHODS: Thirty - six patients (36 eyes) with prior failed sequential trabeculectomy who underwent Ahmed glaucoma valve implantation were included. The intraocular pressure ( IOP), best corrected visual acuity (BCVA) and complications were ovserved and all the patients were followed up at least for 12mo. RESULTS: Mean preoperative IOP was 35. 20±7. 28mmHg and reduced to 10. 15±3. 34, 11. 23±3. 56, 15. 63±5. 72, 17. 17±5. 47, 17. 73±6. 23,19. 76±5. 43mmHg at 1, 2wk, 1, 3, 6 and 12mo after surgery, which was significant different from the preoperative level (t = 12. 643, 11. 837, 10. 324, 8. 839, 8. 462, 8. 046, all P 0. 05). At 12mo after operation, the complete success rate reached 78% and the conditional success rate reached 92%. There were 5 eyes complicated with shallow anterior chamber, 3 eye complicated with anterior chamber hemorrhage, which all recovered after additional treatments. Late complications included valve exposure and encapsulated cystic blebs around the plate. Severe corneal endothelium loss occurred in 1 patient. CONCLUSION: Ahmed glaucoma valve implantation is effective in reducing IOP at 1-year follow-up in refractory glaucoma patients with prior sequential failed trabeculectomy, but we should fully understand and attach great importance to all kinds of complications that may occur.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the therapeutic effect of Yishen Qingre Huashi Recipe (YQHR) in treating proteinuria of chronic glomerular disease patients with Pi-Shen deficiency complicated damp-heat syndrome (PSDCDHS).</p><p><b>METHODS</b>Totally 121 stage 1 -2 primary chronic glomerular disease patients with PSDCDHS were randomly assigned to the treated group (85 cases) and the control group (36 cases) according to 2:1. All patients received conventional and symptomatic treatment. Patients in the treated group took YQHR additionally, while those in the control group took Losartan Potassium Tablet (50 mg each time, once per day) additionally. The therapeutic course for all was 6 months. Changes of 24 h urine protein, blood urea nitrogen (BUN), serum creatinine(SCr), and estimated glomerular filtration rate (eGFR) were observed at different time points. And the difference in therapeutic effects were compared between the two groups.</p><p><b>RESULTS</b>Compared with the control group after 6 months of treatment, 24 h urine protein obviously decreased in the treated group (P <0. 05). There was no statistical difference in SCr, BUN, or eGFR between the two groups after 6 months of treatment (P >0. 05). The total effective rate after 2, 4, and 6 months of treatment in the treated group was 77. 6% (66/85 cases), 82. 4% (70/85 cases), and 89. 4% (76/85 cases), respectively. They were 47. 2% (17/36 cases), 55. 6% (20/36 cases), and 61. 1% (22/36 cases) in the control group, respectively. Compared with before treatment in the treated group, the total effective effect after 6 months of treatment was higher than that after 2 months of treatment (χ2=4. 28, P <0. 01). Compared with the control group at the same time points, the total effective rate in the treated group after 2, 4, and 6 months of treatment was higher (χ2=10. 87, 9. 53, 13.16, P <0. 01).</p><p><b>CONCLUSION</b>YQHR could significantly lower proteinuria in chronic glomerular disease patients with PSDCDHS, improve the clinical effect, thereby providing clinical evidence for treating chronic glomerular disease proteinuria from resolving dampness and clearing heat.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To establish a nested case-control study cohort in myelodysplastic syndrome (MDS) patients and investigate the clinical characteristics, WHO subtype and risk factors associated with MDS evolution to leukemia of this cohort.</p><p><b>METHODS</b>All patients, ≥18 years of age, provided by 24 Shanghai hospitals with initial clinical findings consistent with a hematopoietic abnormality between June 2003 and April 2007, were the candidates for inclusion in this study. The blood and bone marrow samples of every patient should be provided at baseline. Diagnosis was made by incorporating morphologic, immunophenotypic, cytogenetic and molecular features according to WHO classification criteria. Cytogenetic analysis was performed using conventional G-banding karyotyping and fluorescence in situ hybridization (FISH) techniques. Cumulative risk of evolution was estimated by Kaplan-Meier method. Prognostic factors were evaluated by univariate Log-rank method and multivariate Cox proportional hazard models.</p><p><b>RESULTS</b>A total of 435 patients were diagnosed as MDS. The median age of MDS onset was 58(18-90) years, with 248 male patients and 187 female patients (male: female 1.33: 1). The percentage of cases with refractory cytopenia with multilineage dysplasia (RCMD) was the highest (65.5%), while that of refraetory anemia (RA) (2.3%), refractory anenia with ring sideroblast (RARS) (1.1%) and 5q-syndrome (0.5%) was lower. Trisomy 8 (+8) was the most common chromosome abnormalities (71 cases, 12.7%). The mean follow-up time was 20.3 (4.2-57.1) months. Cases were patients with evolution by the end of follow-up, while controls were patients without evolution by that time. Case group included 41 patients and control group included 342 patients. Univariate analysis showed that the age, sex, WHO subtype, WBC count, absolute neutrophil count (ANC), IPSS cytogenetic subgroup, IPSS group and bone marrow blast percentage were significant risk factors for leukemia-free survival (LFS). Multivariate analysis of COX model showed that the age, sex, WHO subtype, IPSS cytogenetic subgroup and bone marrow blast were independent risk factors for LFS.</p><p><b>CONCLUSION</b>A nested case-control study cohort of MDS patients is established. The clinical characteristics and WHO subtype of MDS patients in Chinese Shanghai are different from that in Western countries. The independent risk factors for MDS evolution are age, sex, WHO subtype, IPSS cytogenetic subgroup and bone marrow blast percentage.</p>

ABSTRACT

Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.

ABSTRACT

The TET gene family has been found a few years ago. Recent studies indicated that TET2 (TET gene family 2) plays an important role in DNA demethylation, the epigenetic regulation and normal hematopoiesis. TET2 mutation has been discovered in a spectrum of myeloid malignancies, including myeloproliferative neoplasms (MPN), myelodysplastic syndrome (MDS) and leukemia, which suggest the role of TET2 as a tumor suppressor. In this review the recent results implicating TET2 in hematological malignancies are summarized, including regulatory functions of TET gene epigenetics, TET2 gene and hematopoietic regulation in bone marrow, TET2 gene and hematological disease(MPN, MDS, AML, CMML, lymphoma) and so on.

ABSTRACT

<p><b>OBJECTIVE</b>We used an animal model of collagen-induced arthritis (CIA) to study changes and roles of tyrosine hydroxylase (TH) expressed by CD4+ T cell subsets, and then explore the relationship between CD4+ T cell subset-derived catecholamines and inflammatory responses in CIA.</p><p><b>METHODS</b>Thirty-six male DBA/1 mice were randomly divided into control group, CIA model group (day 35) and CIA model group (day 55) (n = 12). CIA model was induced by type II collagen (CII) in DBA/1 mice. On the 35th and 55th day following primary immunization, the joints of the mice were observed for clinical score of swelling and the level of anti-CII IgG antibody in serum was examined. Expression of specific transcription factors and cytokines of Th1, Th17, Th2 and Treg cells and TH in mesenteric lymph nodes was measured by means of Western blot. The changes of TH expressed by CD4+ T cell subsets in mesenteric lymph nodes were determined by flow cytometry.</p><p><b>RESULTS</b>Clinical score and anti-CII antibody level increased in CIA compared with that in intact mice. Specific transcription factors and cytokines expressed by Th1 and Th17 cells were upregulated and cytokines expressed by Th2 and Treg cells were downregulated in mesenteric lymph nodes in CIA mice. Expression of TH was upregulated and the increased expression of TH in CD4+ T cells was attributed to Th1 and Th17 cells in mesenteric lymph nodes of CIA.</p><p><b>CONCLUSION</b>The increase in catecholamines from CD4+ T cell subsets in mesenteric lymph nodes of CIA may be related to inflammatory alleviation in CIA progression.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Parkinson's disease (PD), a neurodegenerative disorder, has been reported to be associated with brain neuroinflammation in its pathogenesis. Herein, changes in peripheral immune system were determined to better understand PD pathogenesis and provide possible target for treatment of PD through improvement of immune disorder.</p><p><b>METHODS</b>1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was intraperitoneally injected into mice to prepare PD model. Expression levels of pro-inflammatory and anti-inflammatory cytokines and transcription factors of CD4+ T lymphocyte subsets in spleen and mesenteric lymph nodes and concentrations of the cytokines in serum were examined on day 7 after MPTP injection. Percentages of CD4+ T lymphocyte subsets were measured by flow cytometry.</p><p><b>RESULTS</b>MPTP induced PD-like changes such as motor and behavioral deficits and nigrostriatal impairment. Expression levels of the pro-inflammatory cytokines including interferon (IFN)-γ, interleukin (IL)-2, IL-17 and IL-22, in spleen and mesenteric lymph nodes were upregulated and their concentrations in serum were elevated in PD progression. But, the concentrations of the anti-inflammatory cytokines including IL-4, IL-10 and transforming growth factor (TGF)-β were not altered in the two lymphoid tissues or serum of PD mice. In addition, expression of T-box in T cells (T-bet), the specific transcription factor of helper T (Th) 1 cells, was downregulated, but expression of transcription factor forkhead box p3 (Foxp3), the transcription factor of regulatory T (Treg) cells, was upregulated. In support of the results, the numbers of IFN-γ-producing CD4+ cells (Th1 cells) were reduced but CD4+CD25+ cells (Treg cells) were elevated in both the lymphoid tissues of PD mice.</p><p><b>CONCLUSION</b>PD has a dysfunction of peripheral immune system. It manifests enhancement of proinflammatory response and CD4+ T cell differentiation bias towards Treg cells away from Th1 cells.</p>

Objective To explore the effect of nuclear transcription factor kappaB(NF-κB) pathway on proliferation of rat pulmonary artery smooth muscle cells (PASMC) induced by platelet-derived growth factor (PDGF).Methods PASMC isolated from rats and cultured in vitro were divided into 3 groups according to the randomization principle:control group(cultured by M199),PDGF treatment group(cultured by M199 and stimulated by PDGF),PDGF + parthenolide treatment group (cultured by M199 and stimulated by PDGF,and intervented by the NF-κB inhibitors parthenolide).MTT colorimetric assay and flow cytometry were performed to detect cell proliferation and cell cycle distribution.Immunohistochemistry was performed to detect the expressions of NF-κB and COX-2 protein.Fluorescence quantitative RT-PCR was performed to detect NF-κB and COX-2 mRNA expressions.One-way ANOVA was used for statistical analysis,multiple comparisons were analyzed by LSD.Results Compared with the control group,MTT value of PASMC was increased significantly when induced by PDGF at each time points(all P < 0.05).MTT value decreased dramatically after the intervention of NF-κB inhibitor parthenolide(P <0.05).Data from flow cytometry detection showed that cell proportion of S phase and G2 + M phase increased significantly in PDGF treatment group,which had statistical difference compared with control group (all P < 0.05).Compared with PDGF induced group,after the intervention of parthenolide,cell proportion of S phase and G2 + M phase ratio decreased dramatically (P < 0.05).The expressions of NF-κB and COX-2 protein and mRNA were promoted in the PDGF induced group compared with the control group (all P < 0.05).Compared with PDGF induced group,after the intervention of parthenolide,the expressions of NF-κB and COX-2 protein and mRNA decreased dramatically(all P < 0.05).Conclusions PDGF can induce proliferation of PASMC,promote cell cycle process and enhance the expressions of NF-κB and COX-2 protein and mRNA.NF-κB pathway involves in the proliferation of PASMC induced by PDGF.

ABSTRACT

To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group, paraboside B, isonuomioside A, paraboside II, and paraboside III were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.

ABSTRACT

Objective Studies had suggested that risk of leukemia might be associated with occupational or residential exposures to electromagnetic fields and varied at distance to and level of the exposure or type of occupations. Through pooled analyses, etiologic insight on the associations between exposure and disease might be explained. Methods We carried out a Meta-analysis based on primary data (1980-2010) from 9 studies related to the electric and magnetic fields exposure and acute myeloid leukemia in adults to assess whether the combined results, adjusted for potential confounding, would indicate an association between them. Results In this study the overall estimated OR value was 1.24(95%CI: 1.11-1.37). The odds ratios for exposure categories of 0.1-0.2 μT, ≥0.2 μT, compared with <0.1 μT, were 1.17(95%CI: 0.98-1.39) and 1.51 (95%CI: 1.15-1.98),respectively. Conclusion Through employing the alternate cut points, stratification by level of exposure or distance and the relation on different ways of exposure, there appeared consistent evidence of increased risk between acute myeloid leukemia in adults and the extremely low frequency-electromagnetic to field exposure.
