Objective To investigate the relationship between brachial-ankle pulse wave velocity (baPWV)and different stage of cardiac dysfunction.Methods 253 consecutive patients with coronary atherosclerotic heart disease were enrolled from August 2006 to February 2007.Patients were grouped according to the functional classification of New York Heart Association(NYHA).The baPWV was measured non-invasively with a VP1000 automated PWV/ABI analyzer(PWV/ABI,Colin CO.Ltd.,Komaki.Japan).At the sanle time,BNP,EF,LAEDV and LVESV were measured in all the patients.Results Brachial-ankle PWV was significantly correlated with cardiac function classification of NYHA(r=0.444.P＜O.001),BNP(r=0.394,P＜0.001)and left ventriculat end diastolic volume(r=-0.130,P＜0.05),The under area of receiver operating charachateistic(ROC)curve was 73.9%.The ROC curve demonstrated that when the value of brachial-ankle PWV was equal to or larger than 1717 cm/s(≥1717 cm/s),the sensitivity of diagnosing mild cardiac dysfunction was 72.9%and specifity 61.8%.When its value was equal to or larger than 1900 cm/s(≥1900 cm/s),the sensitivity and specificity were 61.5%and 81.9% respectively.Conclusion Brachial-ankle PWV is significantly correlated to the NYHA classification of heart failure and it may be a prospective index to diagnose early stage of cardiac dysfunction.

Objective Dynorphins have advantages in powerful analgesic effect, high safety, no respiratory depression and no addiction, which is the emphasis of analgesic research at present. The aim of the article was to explore the expression of lentivirus-mediated rat prodynorphin gene in bone marrow mesenchymal stem cells( BM-MSCs) and contribute to the subsequent studies on bio-logical analgesia in cancer pain of rat model. Methods BM-MSCs were isolated and proliferated using the adherence screening meth-od, and further identified by flow cytometry, adipogenic and osteogenic differentiation experiments. The PDYN lentiviral vectors in rats were transfected into BM-MSCs after construction. The expression of green fluorescent protein (GFP) was detected under inversion fluo-rescence microscope and the best multiplicity of infection ( MOI ) of virus was screened by western blot. There are three groups in the ex-periment: blank group, experimental group ( PCDH-CMV-PDYN-EF1-copGFP ) and empty vector group ( PCDH-CMV-MCS-EF1-copGFP). PYDN gene was determined by qPCR and western blot, while DYN protein was detected by immunochemical method.Results BM-SMCs were in longspindle-shape and fibrocyte-like adherent growth, most in expression of CD29, CD44 and CD90, and a few in CD45. The oil red-O staining of the induced cells by adipogenic differentiation was positive. The mineralized nodules formed in the induced cells by osteogenic differentiation were orange after alizarin red staining. Flow cytometry detection showed the positive rates of CD29, CD90, CD44 and CD45 were respectively (99.80±0.19)%, (99.62±0.24)%, (96.86±1.27)%, (0.82±0.06)%, while after transfection the positive rates were (99.59±0.34)%, (98.06±1.27)%, (95.23±0.71)%, (10.23±0.59)%, representing no sig-nificant difference before and after PDYN transfection. Lentiviral vector of PCDH-CMV-PDYN-EF1-copGFP was successfully construc-ted after the identification of PCR amplification, cloning and sequencing. The titer of recombined lentiviruses was 5×106IU/mL. The best MOI of lentiviruses was 100 according to the results of GFP and western blot. Western blot and qPCR suggested PDYN gene signif-icantly increased in BM-MSCs after lentiviral transfection ( P<0.05) , and immunohistochemical staining indicated DYN protein also in-creased greatly. Conclusion BM-MSCs are successfully cultured and the overexpressed rat PDYN gene lentivirus vector is also suc-cessfully constructed;PDYN gene is highly and stably expressed and DYN protein is secreted in BM-MSCs.

Objective To review the efficacy and safety of brucea javanica oil in the adjuvant therapy of primary hepatocellular carcinoma (HCC).Methods China National Knowledge Infrastructure (CNKI),China Biology Medicine (CBM),VIP,Wanfang database,Pubmed,Web of Science,ScienceDirect,and Cochrane Library were searched from their inception to December 2015.Then contact with the field experts and correspondence authors for gray literature.Two reviewers independently searched the databases,performed data extraction,and appraised the publications.The Reviewer Manager 5.3 software was employed for data analysis.Results Fifteen clinical trials with 1 128 HCC patients were included.Meta-analysis confirmed that the brucea javanica oil group,compared to the control group,was more advantageous to reduce the incidence of postoperative fever,bone marrow suppression,and gastrointestinal reaction.In addition,it might reduce the level of alpha fetoprotein (AFP),enhance immunity,and improve clinical symptoms.However,more evidence would be needed to support these results.Conclusions Brucea javanica oil is considered to reduce toxicity and increase efficiency in the adjuvant therapy for the HCC,but more high quality,multi-center,large sample,randomized,double-blind clinical trials are also needed for supporting this view.

Objective To investigate the changes in femoral gene expression profiles in C57BL/6 mice fed high-fat diet (HFD) via clustering analysis of DNA microarray.Method Sixteen male C57BL/6 mice (4w old) were randomly assigned to two groups,8 in each,after 4-d ordinary diet for adaptation.The control group was fed with an ordinary diet,and the HFD group with HFD(19.5% lard).All mice were sacrificed at the end of 12w and the femoral gene expression was detected by oligonucleotide microarray analysis with Affymetrix Gene Chip Mouse U430A.DAVID,an online tool,was used for clustering analysis on femoral gene expression.Results Longtime administration of HFD caused femoral gene expressed differences related to cation ion channel,transcription regulation and signal transduction,bone mineralization,phosphate metabolic process regulation,and collagen synthesis.Conclusion Longtime intake of HFD will change the expression of numerous bone metabolism-related genes in bone of mice,and then inhibit bone formation.

Objective: To observe the impact of mind-regulating acupuncture plus donepezil on the cognitive ability, mean cerebral blood flow velocity, event-related potential P300, and activities of daily living (ADL) in the aged patients with Alzheimer disease (AD).Methods: Sixty senile AD patients were divided into a treatment group and a control group following the envelope method for random allocation, with 30 cases in each group. Based on the conventional treatment of the internal medicine, the control group received oral donepezil, and the treatment group received oral donepezil plus mind-regulating acupuncture. After 4-week treatment, the two groups were evaluated by the mini-mental state examination (MMSE), Alzheimer disease assessment scale-cognitive part (ADAS-Cog), and ADL; changes in P300 and the mean cerebral blood flow velocity were also observed.Results: Before treatment, there were no significant differences in the scores of MMSE, ADAS-Cog, or ADL between the two groups (P>0.05). The MMSE score increased after treatment in both groups and was notably higher in the treatment group than in the control group, showing intra-group and inter-group statistical significance (P<0.05). After treatment, the ADAS-Cog and ADL scores dropped in both groups and were markedly lower in the treatment group than in the control group, also showing intra-group and inter-group statistical significance (P<0.05). Compared with the same group before treatment, the latency of P300 was shortened and the amplitude was extended in both groups, all with statistical significance (P<0.05); the latency was shorter and the amplitude was larger in the treatment group than in the control group after treatment, presenting significant between-group differences (P<0.05). The mean blood flow velocity accelerated after the intervention in both groups, and the differences were statistically significant (P<0.05); the improvement in the treatment group was more notable than that in the control group (P<0.05).Conclusion: Mind-regulating acupuncture plus donepezil can regulate the latency and amplitude of P300, increase cerebral blood flow, and improve the learning and memory abilities of AD patients.

To investigate the effects of Changweiqing-medicated serum, which was prepared with a compound traditional Chinese herbal medicine, on the reversal of oxaliplatin (L-OHP) resistance and the relationship between the reversal and cellular accumulation of platinum and proteins associated with copper transporter in HCT116/L-OHP cells.

Lymphomatous involvement of the gallbladder is rarely identified and manifests mostly as a local involvement of disseminated disease. There have been reported only about 20 primary malignant lymphomas of the gallbladder without involvement of other sites. A 63-year-old woman presented with jaundice, epigastric pain, and weight olss of two months duration. There was no systemic lymphadenopathy elsewhere. Abdominal computed tomograph revealed a focal thickening of the gallbladder wall. The removed gallbladder contained a well circumscribed, 5x3 cm-sized, slightly elevated firm area with accentuated mucosal papillary excrescences near the neck protion. The lesion involved whole thickness of the wall, and was made up of diffuse atypical lymphoid cell infiltrates of variable size accompanying plasmacytoid differentiation in areas. Some large tumor cells were pleomorphic and contained prominent nucleoli. To our knowledge, this is the first case of primary malignant lymphoma of the gallbladder in Korean literature.

MicroRNA (miRNA for short) can induce mRNA cleavage or inhibit mRNA translation and regulate gene expression in the post-transcriptional level, which involves cell development, proliferation, differentiation, apoptosis, and a series of important biological processes. Recent studies have found that the abnormal regulation of miRNA's target genes may be involved in tumor resistance. And it is expected to become important tumor resistance-associat-ed molecular markers and therapeutic targets. Mechanism of traditional Chinese medicine (TCM) and its active ingre-dients can affect miRNA to regulate target proteins and target genes mediated tumor multidrug resistance. It can pro-vide new ideas for the mechanism of reversing multidrug resistance by TCM.
