Objective To investigate the relationship between leptin receptor(LEPR) gene Gln223Arg in polymorphism and serum leptin level of patients with asthma.Methods A case-control study was conducted.One hundred and ninety-two asthma patients were recruited from asthma gene library,among them 100 patients only with asthma(asthma group) and 92 patients with both asthma and metabolic syndrome(asthma complicated with metabolic syndrome group).And 108 normal people were selected as control group.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphism of LEPR gene Gln223Arg locus.Serum leptin levels were measured by enzyme-linked immuno sorbent assay,its relationship with asthma was analyze.Results The frequencies of genotype GG,GA,AA in asthma group,asthma complicated with metabolic syndrome group and normal control group were (83.00％ (83/100) vs.83.70％ (77/92) vs.70.37％ (76/108),15.00％ (15/100) vs.15.22％ (14/92) vs.27.78％ (30/108),and2.00％ (2/100) vs.1.08％ (1/92) vs.1.85％ (2/108) respectively).G and A alleles in asthma group,asthma complicated with metabolic syndrome group and normal control group were 90.50％ vs.91.30％vs.84.26％,9.50％ vs.8.70％ vs.15.74％ respectively.Compared with the control group,GG genotype and GA + AA genotype were different between in asthma group and asthma complicated with metabolic syndrome group.The patients with GG genotype showed 2.056 (x2 =4.599,P =0.032,OR =2.056,95％ CI =1.057-3.999) and 2.161 folds (x2 =4.907,P =0.027,OR =2.161,95 ％ CI =1.084-4.311) risk in asthma group and asthma complicated with metabolic syndrome group than that with GA + AA genotype.In terms of leptin levels,in asthma group,female were significant higher than that of control group (P =0.037,P =2.93),while in asthma complicated with metabolic syndrome group,male and female were significantly higher than control group (P =0.001,0.000 ; P =4.530,4.690).Conclusion The polymorphisms of LEPR gene locus Gln223 Arg are related with asthma.Genotype GG carrier is susceptible for the disease.In female,serum leptin is positive relationship with asthma group,especially in asthma complicated with metabolic syndrome.

OBJECTIVE:To provide some references for rational application of intravenous infusion drugs to ensure the safety of drug use. METHODS:Statistical analysis was made to irrational prescriptions intercepted by the pharmacy intravenous admixture service of our hospital from 2009 to 2013. RESULTS:There were 5,802 groups of irrational prescriptions from 2009 to 2013,accounting for 0.12% of total prescriptions. For the irrationality,the top three reasons were improper solvent dosage, drug overdose and improper solvent selection in order,and the involved types of drugs were mainly antimicrobial agents,anti-neoplastic drugs,common drugs and parenteral nutrition drugs (arranged from more to less). Under the pharmacist’s interven-tion,the percentage of irrational prescriptions of intravenous drugs reduced from 0.169 4% in 2009 to 0.082 8% in 2013. The decrease in the irrational prescriptions involving with improper administration was the most significant,followed by those related to drug overdose,frequency,prescribing errors errors improper solvent dosage,incompatibility and improper solvent. CONCLU-SIONS:Pharmacists’intervention can effectively reduce the irrational prescriptions and significantly promote rational use of in-travenous drugs.

Aim To investigate the effect of the inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA)reductase enzyme,simvastatin on E-Selectin ex-pression and adhesive function assay induced by CD40L.Methods Human umbilical vein endothelial cell(HUVEC)was cultured from ECV304 cell strain.Then E-Selectin expression and adhesion of lymphocytes to endothelial cells induced by CD40L and interfered with different concentrations of simvastatin or simvastatin(5 ?mol?L-1)+mevalonic acid were determined by RT-PCR and FCM analysis.Results Preincubation of HUVECs with simvastatin(0~10 ?mol?L-1)decreased the expression of E-Selectin induced by CD40L in a concentration-dependent manner.Mevalonic acid(400 ?mol?L-1)inhibited the restrain of simvastatin on E-Selectin expression.Moreover,preincubation with simvastatin,decreased significantly adhesion of lymphocytes to endothelial cells induced by CD40L.Conclusions Simvastatin inhibits activation of endothelial cells induced by the CD40L/CD40 pathway through HMG-CoA dependent effect.

The origin of nerves innervating the small intestine and oral part of the colon of the cat was studied by means of the retrograde axonal transport of HRP. Twelve adult cats were used in this experiment. The proximal cut end of the superior mesenteric plexus was immersed in HRP solution, in order to localize the neurons which contribute fibers to this plexus. Neurohistochemical procedures were processed according to Mesulam's tetramethylbenzidine (TMB) method. HRP labeled cells or fibers can be identified bilaterally in the following places: 1. The dorsal motor nucleus of the vagus nerve; about 80% of the labeled cells were found in a region from 0.4mm below to 2.0 mm above the obex, approximately at the rostral two-thirds of the middle segment of this nucleus. 2. The reticular formation of medulla; only a few cells labeled and 92% of them were located in an area from 0.2, mm to 2.7 mm above the obex. 3. The coeliac-superior mesenteric ganglion complex; almost all of the labeled cells were concentrated in the caudal part of it, near the origin of the superior mesenterie plexus. 4. The nodose ganglion; most of the oval or round labeled cells were of medium or small size, their diameters vary from 30 to 40?m, and the average total numbers of the labeled cells were 661 in the left and 695 in the right ganglion respectively. 5. The spinal ganglia; small round or oval labeled cells (25～45 ?m in diameter) were found in the left T_2 to L_5 and right T_2 to L_4 ganglia, with the most heavily labeled segments at T_(13) and L_1 (left, mean 365; right, mean 34% of all labeled cells). The average total number of the labeled Cells were 1872 in the left and 1698 in the right side. 6. Transganglionic labeled fibers were seen in the gracile nuclei of one cat, suggesting that HRP molecules are transported retrogradely in the peripheral process and anterogradely in the centrally projecting process of the same neuron of spinal ganglia.

Objectives To establish real-time fluorenscence quantitative polymerase chain reaction ( RFQ-PCR ) for measurement of the expression level of guanylyl cyclase-C(GC-C) in the Peripheral blood mononuclear cell(PBMC)in 30 blood donors, 10 cases colorectal cancer tissue and 1 case T84 human colon cancer cell line. Methods Specific primers and TaqMan probe have been designed,and fluorenscence of the PCR product was detected continuously during amplification. According to the standard curve created by plasmid DNA, the expression level of GC-C in clinical samples has been determined using software, and the results were presented as the ratios of GC-C mRNA to?2-microgluobulin(?2M)mRNA. Results The detection range of the assay was from 101 pg/ml to109pg/ml,the coefficient of variation values of both intra-experimental and inter- experimental reproducibility were 6. 87% to 11. 12% and 8. 86% to 15. 19% . None of 30 blood donors and 11 benign intestinal patients expressed GC-C mRNA,it was expressed in 31/37 colorectal cancer patients. The expression level of GC-C mRNA in colorectal cancer patients was 0. 88?0.06,and the expression level of its in colorectal carcinoma tissue and T84 cells were 0. 86?0.07/ug tissue and 0.0082/per cell. Conclusions This assay had high sensitivity,specificity and reproducibility.
