Objective To explore the optimal cut-off points of body mass index(BMI),percentage of body fat(PBF) and body fat mass index(BFMI) for identification of cardiovascular risk factors clustering among elderly males. MethodsThe data of physical examinations from 1 052 Shanghai elderly males in 2007 were collected.The relationship between cardiovascular risk factors clustering and different strata of BMI,PBF and BFMI was analyzed.Receiver Operator Characteristic(ROC) curve analysis was employed to determine the optimal cut-points for identification of cardiovascular risk factors clustering,and area under curve(AUC) was worked out.The population attributable risk proportion(PARP) of risk factors clustering was calculated. Results Odds ratios of risk factors clustering tended to increase with BMI,PBF and BFMI.BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 were the cut-off points that had approximate sensitivity and specificity,and/or had the shortest distance in ROC curve.AUC of all the three indexes was larger than 0.5.Analysis of PARP indicated that BMI under 24 kg/m2,PBF under 21% and BFMI under 5 kg/m2 could prevent 27.1%,37.44% and 36.63% risk factors clustering,respectively. Conclusion BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 can well reflect the cardiovascular risk factors clustering among elderly males.

Long non-coding RNA(LncRNA)is a class of RNA that cannot encode translated proteins with more than 200 nucleotides in length.It can be involved in the regulation of X chromosome silencing,chromatin modification,transcriptional activa-tion,transcriptional interference and other regulatory processes by binding to DNA,RNA or proteins.In recent years,more and more studies have confirmed that LncRNA plays an important role in the occurrence,development,invasion and metastasis of gastric cancer. At the same time,many studies have demonstrated LncRNA as the target of traditional Chinese medicine for the development and pro-gression of anti-gastric cancer.This review introduces the mechanism of LncRNA in the development and progression of gastric canc-er,and as a target for traditional Chinese medicine treatment prospects.

The aim of the study is to evaluate the effects of the single and mixed decoction of Thallus laminariae (kelp) and Glycyrrhiza glabra (licorice) on the metabolism and their difference. The mixed decoction of kelp and licorice and the single decoction were made and intragastrically administered to the SD rats. The effect on system metabolism, the toxicity of liver and kidney were assessed by GC-MS profiling of the endogenous molecules in serum, routine biochemical assays and histographic inspection of tissues from SD rats, separately. The mixed decoction of kelp and licorice induced more obvious pathological abnormalities in SD rats than a single decoction of kelp, while the extracts of licorice did not show any pathological change. Neither the mixed, nor the single decoction showed abnormal histopathology. After intragastric administration of extracts for 5 days, the mixed decoction induced a decrease of ALT (no significant change in the groups of single decoction) and an increase of BUN (so did the single decoction of kelp). Metabolomic profile of the molecules in serum revealed that the metabolic patterns were all obviously affected for the three groups, i.e., the mixed and single decoction of kelp and licorice. The rats given with the single decoction of kelp showed a similar pattern to that of the mixed decoction, indicating that the kelp primarily contributed the perturbation of metabolism for the mixed decoction. All three groups induced a decrease of branched chain amino acids, TCA cycle intermediates and glycolysis intermediates (e.g., pyruvic acid and lactic acid) and an increase of 3-hydroxybutyric acid. Kelp decoction showed stronger potential in reducing TCA cycle intermediates and glycolysis intermediates than the other two groups, while the levels of branched chain amino acids were the lowest after licorice extracts were given. These results suggested that the effect of the mixed decoction on metabolism was closely associated with both kelp and licorice. The continuous administration of single decoction of kelp and the mixed decoction of licorice and kelp resulted in pathological abnormalities in kidney of SD rats. The mixed decoction of kelp and licorice distinctly perturbed sera molecules and hence system metabolism, which showed associated with those of kelp and licorice. Although the metabolic effect was associated with both kelp and licorice, the results suggested kelp contributed to it primarily.

To explore the efficacy of sorafenib combined with chemotherapy and donor lymphocyte infusion (DLI) in patients with FLT3-positive acute myeloid leukemia (AML) relapsed after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Of the 14 patients relapsed after allo-HSCT,9 achieved complete remission after salvage therapy of sorafenib combined with chemotherapy and DLI,6 with complete molecular remission,2 with partial remission,and 3 with no response.With a median follow up of 220 (range,30-1 782) days after post-transplantation relapse,7 patients were still alive and 7 died.Salvage therapy of sorafenib combined with chemotherapy and DLI shows a decent therapeutic effect for FLT3-positive AML relapsed after allo-HSCT.

OBJECTIVETo compare the anti-inflammatory and anti-nociceptive effects of the different water extracts which were prepared by regular decoction time or removing volatie oil and ethanol extracts which were prepared in different concentration ethanol of Xixin (the roots and rhizomes of Asarum heterotropoides var. mandshuricum), and then to investigate the anti-inflammatory and antinociceptive mechanisms.

METHODXylene-induced ICR mouse ear edema and hot plate test were utilized to evaluate the anti-inflammatory and anti-nociceptive effects of Xixin at different dose level (water extracts of regular decoction time or removing volatie oil at the dose of 0.8 g x kg(-1) and 1.6 g x kg(-1); 95% ethanol extracts at the dose of 0.91 g x kg(-1) and 1.82 g x kg(-1); 50% ethanol extracts at the dose of 0.76 g x kg(-1) and 1.52 g x kg(-1)). Xylene-induced adrenalectomized mouse ear edema model was used to study the anti-inflammatory mechanisms. To reveal the anti-nociceptive mechanisms, mice were pretreated with naloxone in the hot plate test.

RESULTThe water extracts significantly reduced the weight of ear edema as compared with control group. Inhibition ratios were 43.20% and 63.69% at the higher dose, respectively. The ethanol extracts also significantly reduced the weight of ear edema and the inhibition ratios were 61.86% and 52. 56% at the higher dose, respectively. Mice administered water extracts delayed the latency times in the hot plate test. The anti-nociceptive effects of water extracts peaked at 2.0 h after i.g. administration. The hot plate latency times were increased by 51.27%, 62.78%, 60.08% and 68.00% at peak time, respectively. Regular decoction time group showed more significant effects in both models. The anti-inflammatory effect of 95% ethanol extracts was similar to 50% ethanol extracts. The water extracts were not effective in reducing xylene-induced adrenalectomized mouse ear edema. The anti-nociceptive effect of water extracts was blocked by naloxone.

CONCLUSIONBoth the water extracts and ethanol extracts of Xixin showed considerable anti-inflammatory potency against xylene induced inflammation. The water extracts produced anti-nociception in thermal model. The water extracts prepared in regular decoction time showed better anti-inflammatory and anti-nociceptive effects. Both the 95% ethanol and 50% ethanol extracts showed similarly anti-inflammatory effects. The anti-inflammatory effect of water extracts related to adrenal gland. The anti-nociceptive effect of water extracts was involved in activating opioid receptor.

OBJECTIVETo explore the etiopathogenesis, therapy and incidence of pulmonary infection in kidney transplantation recipients taking new immunosuppressant.

METHODSThe clinical data from 752 kidney transplant recipients were retrospectively analyzed, who were divided into 3 groups according to the immunosuppressants administered, namely group A (CsA+MMF+Pred, n=226), group B (FK506+MMF+Pred, n=386) and group C (FK506+Rap+Pred, n=140). The incidence and mortality of pulmonary infection were recorded and the analysis of etiopathogenesis, diagnosis and therapy of pulmonary infection were carried out in the 3 groups.

RESULTSFifty-three patients acquired post-transplant pulmonary infection. The incidence of pulmonary infection was 7.08% (16/226) in group A, 7.25% (28/386) in group B and 6.43% (9/140) in group C. One patient died in group A and 2 in group B. Among the 53 patients, 24 had simple bacterial infection, 9 had cytomegalovirus infection, 1 had mycotic infection, 17 had combined infection, and 2 had unidentified pathogen infection. Of the pathogenic bacteria detected, 68.35% were Gram-negative.

CONCLUSIONGram-negative bacteria are most likely responsible for pulmonary infection after kidney transplantation, which most possibly occurs within 6 months after kidney transplantation. Early diagnosis and early treatment are critical for decreasing the mortality of severe pneumonia and for improving the survival rate of the patients and grafts.

Objective To explore the effect of KCNQ1OT1 gene knockout combined with bruceine D on the proliferation, migration, and invasion of breast cancer MDA-MB-231 cells. Methods Cell Counting Kit-8, wound healing, and Transwell invasion assay were used to detect the effects of bruceine D and siKCNQ1OT1 on the viability, migration, and invasion of MDA-MB-231 cells. Effect of bruceine D and siKCNQ1OT1 on the expression of KCNQ1OT1 in MDA-MB-231 cells was detected by qRT-PCR. Western blot was used to detect the effect of bruceine D and siKCNQ1OT1 on the expression of EMT-related proteins and CDC42, p-MKK7, MKK7 proteins in MDA-MB-231 cells. Results Bruceine D and siKCNQ1OT1 could significantly inhibit the viability, migration, and invasion of MDA-MB-231 cells, and the inhibitory effect was enhanced when they were combined (all P < 0.05); bruceine D downregulated the expression of KCNQ1OT1 in MDA-MB-231 cells (all P < 0.05); bruceine D combined with siKCNQ1OT1 significantly decreased CDC42, p-MKK7, N-cadherin, and Vimentin expression in MDA-MB-231 cells and increased the expression of E-cadherin (all P < 0.05). Conclusion Bruceine D combined with siKCNQ1OT1 significantly inhibit the proliferation, migration, invasion, and EMT of human breast cancer MDA-MB-231 cells, and its molecular mechanism may be related to the blocking of CDC42/MKK7 signaling pathway.
