Objective:To explore the methods for drug therapy regimen formulation and pharmaceutical service of clinical pharma-cists for the infection induced by peripherally inserted central catheter ( PICC) complicated with deep venous thrombosis in cancer pa-tients. Methods:Referring to the related guide, clinical pharmacists put forward concrete opinions on how to choose anti-infective drugs and anti-thrombotic drugs for a cancer patient with PICC infection complicated with deep venous thrombosis. Clinical pharmacists sug-gested that vancomycin be used for the infection and low molecular weight heparin sodium for prophylactic anticoagulation. Meanwhile, pharmaceutical care for blood clotting function should be strengthened. Results:The proposals of clinical pharmacist were partly adopt-ed by clinicians. After the therapy, the temperature of the patient returned to normal, and the deep venous thrombosis was well con-trolled. The patient was out of hospital smoothly. Conclusion:Through the participation in clinical practice, clinical pharmacists can assist physicians in optimizing treatment plan and summarize the pharmaceutical care mode for the PICC infection and deep venous thrombosis in cancer patients, which can provide instructions for pharmaceutical care in the future.

Although the concept of united airway disease has been widely accepted, most scholars emphasize only the effect of rhino-sinusitis while ignoring the pharyngeal factors to the lower airway, especially to the allergic pharyngitis (AP), which still lacks enough awareness. First of all, absence of unified diagnostic standard leads to the lack of epidemiological data, which, results in doctors' personal experience but no guideline in treatments. In addition, it is still not clear that the role of AP in the allergic airway diseases and its relationship with asthma. However, the number of patients with AP has been increasing obviously in daily clinic practice. Combined with the previous observation, this paper does a systematic review about the clinical problems of AP, expecting to give a hand to the clinical diagnosis and treatment of AP.

Objective To explain the effects of C-reactive protein(CRP) on lectin-like oxidized low density lipoprotein receptor-1 expression on THP-1 derived macrophages and the related signal transduction pathways.MethodsTHP-1 cells were differentiated into macrophages with the stimulation of PMA.THP-1 derived macrophages were incubated with CRP and co-incubated with inhibitors of NF-?B、AP-1 and MARK signal transduction pathways.The expression of LOX-1 antigen and mRNA was analyzed by ELISA and RT-PCR.Results CRP stimulated the expression of LOX-1 antigen and mRNA on macrophages in a dose-dependent manner.NF-?B inhibitor BAY11-7085 suppressed the inducible effects of CRP on LOX-1 expression.Conclusion CRP increased LOX-1 expression on THP-1 derived macrophages at transcription and post-transcription levels.The NF-?B signal transduction pathway may be involved in such process.

Hepatocellular carcinoma ( HCC) , as one of the most common malignant neoplasms , has a relatively high morbidity and mortality rate worldwide.MicroRNAs (miRNAs),a type of comparatively conserved endogenous small non-coding RNAs, function as pivotal regulators involved in various biological functions through the post -transcriptional regulation of gene expression .Some miRNA genes are arranged into a intandem model and reside close together on the same chromosome , forming miRNA clusters . These clustered miRNAs are mostly located on polycistronic transcripts and expressed at similar levels.In the human imprinted 14q32 region, 52 miRNA genes are organized as a large cluster which spans about 220 kb of the long arm ( q) .Lines of evidence show that dysregulation of miRNAs in this cluster are involved in the development of HCC .This review summarizes the structural characteristics of 14 q32 miRNA cluster as well as its impact on HCC in initiation and progression .

Objective To develop and validate a ultrasonographic (US)imaging agent with targeted microbubbles that attaches to chemokine receptor 2 (CCR2)and to compare the US single obtained from targeted microbubble with that from control microbubble in murine breast tumor model.Methods The microbubble which carried CCR2 antibody (MBCCR2 )and isotype-macthed immunoglobulin G-labled control microbubble (MBcontrol ) were prepared. The microbubble size and distribution were assessed by AccuSizer780.Binding specificities of targeted microbubble compared with control microbubble were tested with murine microvascular endothelial cells (bEnd.3 ).Orthotopic breast tumor model was estabished in BALB/c mice with mouse breast cancer 4T1 cell.In vivo imaging signals of contrast material-enhanced ultrasound by use these two different types of microbubble which were injected respectively into each mouse at random order and 30 min interval.Tumor tissue was stained for CCR2 and CD3 1 .Results Automatic Particle Sizer showed size uniform of two kinds of microbubbles,and narrow distribution of particle size (mean diameter of about 1 -2 μm),which were not significantly different (P >0.05).Adhension to bEnd. 3 endothelial cells was significantly higher (P < 0.001 )for MBCCR2 (mean,9.50 ± 1 .5 1 )than that for MBcontrol (mean,0.01 ±0.01).Imaging signal in the murine tumor model was significantly higher for MBCCR2 [mean,(6.76±0.26)dB]than that for MBcontrol [mean,(1 .06 ±0.62)dB,P <0.001 ].Immunofluorescence confirmed expression of CCR2 on tumor vasculature.Conclusions The targeted microbubbles with CCR2 monoclonal antibody had been successfully prepared,which precisely targeted to CCR2 of tumor angiogenesis in the murine breast cancer xenograft tumor models in vivo.These results suggest that the targeted microbubbles as a kind of ultrasound molecular imaging agent with a better specificity can be used for both evaluating tumor neovascularization and monitoring therapeutic effect of anti-angiogenesis.

Objective To study the relationship between intradialytic hypertension (IDH) and inflammatory factors in patients with maintenance hemodialysis.Methods Forty maintenance hemodialysis patients were involved,including 20 patients with IDH (IDH group) and 20 patients without IDH(non-IDH group) during hemodialysis.All of them had no sign of acute infections or other progressive disease.The levels of C-reactive protein (CRP),interleukin (IL)-1 β,IL-6,tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA) before hemodialysis and 1,2,4 h after hemodialysis.The correlation of hypertension to CRP,IL-1 β,IL-6,TNF-α was analyzed.Results The levels of CRP,IL-1β,IL-6,TNF-α were increased in IDH group with the progress of hemodialysis,but were stable innon-IDH group.Logistic regression analysis indicated that there were positive correlations between CRP (r =0.3652),IL-1β (r =0.3261 ),IL-6(r =03156),TNF- α (r =0.3324) and blood pressure during hemodialysis (P ＜ 0.01 ).Conclusion The levels of CRP,IL-1β,TNF-α,IL-6 are positively related to the IDH in maintenance hemodialysis patients.

Objective To evaluate the performance of homocysteine(Hcy)test kit produced by a domestic company and to inves-tigate its feasibility in clinical application.Methods A series of methodological evaluation experiments including the accuracy,re-peatability,stability and linear range of the Hcy reagent kit were carried out on the Olympus Au640 biochemistry analyzer.Results The experiments showed that the relative biases of detection results of normal value quality control serum and pathological value quality control serum were 0.2% and 4.9%,respectively,which were far less than 15% of the reagent instruction.The intra-assay coefficients of variation(CV)of normal and pathological quality control serum were 2.6% and 2.3% respectively,which were less than 5% of the reagent instruction.While the inter-assay CV of normal and pathological quality control serum were 4.4% and 4.1% respectively,which were less than 10% of the reagent instruction.The experiments for the linear range evaluation showed that R 2 was 0.997 in the concentration range of 0 -66 μmol/L,which suggested that the correlation between expected value and measured value was very well.Otherwise,the slope rate b1 of 0.979 9 and the intercept b0 of 0.151 8 were both showed that the de-tection results of Hcy reagent were linear in the concentration of 0-66 μmol/L.Conclusion The performance of Hcy kit produced by a domestic company is very good in the performance indexes of accuracy,repeatability,stability,and linear range and suitable for the clinical application.
