Objective To observe and analyze curative efficacy of Desloratadine Citrate Disodium in combination with endoscopic sinus surgery and its effects on serum TIgE, ECP and inlfammatory factors in patients with chronic sinusitis.Methods 90 patients with chronic sinusitis who received therapy in our hospital from January 2015 to June 2016 were collected as research objects to be randomly divided into the control group and the observation group equally. The control group was given endoscopic sinus surgery, and the observation group was given Desloratadine Citrate Disodium in combination with endoscopic sinus surgery. Then, visual analogue scale (VAS) was applied to assess the severity of subjective symptoms of the disease. Three months after the surgery, the curative efifcacy, scores of visual analogue scale (VAS) relfecting clinical symptoms, levels of serum TIgE, ECP and inlfammatory factors were compared between the two groups.Results All patients undergone successful surgery. The observation group had a total therapeutic efifciency ratio of 95.6%, which was signiifcantly higher than that of 82.2% in the control group (P < 0.05). In comparison with the control group, the observation group had lower VAS scores of nasal discharge, nasal obstruction, cheek pain, headache, hyposmia [(1.84 ± 0.89) vs (3.12 ± 1.03) points, (1.87 ± 0.81) vs (2.55 ± 1.14) points, (1.24 ± 0.86) vs (1.88 ± 0.79) points, (1.15 ± 0.54) vs (1.97 ± 0.83) points, (1.84 ± 0.73) vs (2.18 ± 0.84) points], lower levels of serum TIgE, ECP [(58.62 ± 7.36) vs (64.39 ± 7.18) kU/L, (4.25 ± 0.84) vs (5.01 ± 1.07) ng/L)] and inflammatory factors of TNF-α, IL-6, IL-8 [(1.27 ± 0.46) vs (2.62 ± 0.53) ng/ml, (5.13 ± 1.24) vs (9.54 ± 2.23) pg/ml, (282.63 ± 32.42) vs (315.84 ± 35.89) ng/L)] with statistical differences (allP < 0.05).Conclusion Desloratadine Citrate Disodium in combination with endoscopic sinus surgery is effective for chronic sinusitis, which can signiifcantly relieve clinical symptoms, reduce levels of serum TIgE, ECP and alleviate inlfammatory reaction.

Objective To investigate colonization of multidrug-resistant organisms (MDROs)in neonatal intensive care unit (NICU)newborns on admission.Methods From April to November 2013,293 newborns who admitted to NICU of a hospital were screened for methicillin-resistant Staphylococcus aureus (MRSA)by nasal and throat swabs and for extended-spectrumβ-lactamases (ESBLs)bacteria and vancomycin-resistant Enterococcus (VRE)by anal swabs.Results Of 293 newborns,61 were detected MDROs (20.82%).The positive rate of MDROs screening in newborns aged <3 days(5.92%)was lower than those aged <3-6 days(37.74%)and 7-28 days (43.66%), the difference was significant (P =0.000).The major colonized MDROs were ESBLs-producing bacteria(83.60%), the major colonized site was anus(88.52%).Conclusion Neonatal anus and stool are important sources of MDROs in NICU;more attention should be paid to colonization screening for MDROs by anal swabs in newborns aged >3 days,and appropriate isolation measures should be taken for positive screening patients to prevent the transmission of MDROs.

Objective By comparing the biological characteristics among Lewis lung cancer cells ( LLC) , LLC or-thotopic transplantation derivative cells ( R1-LLC) and R1-LLC orthotopic transplantation derivative cells ( R2-LLC) , we e-valuate their invasion and metastatic abilities in orthotopic transplantation models.Methods In vitro, we applied CCK8, clonogenic assay, and Transwell invasion assay to detect the proliferation ability, invasion ability and morphologic structures of LLC,R1-LLC, R2-LLC cells respectively, meanwhile observing morphologic structures by transmission electron microsco-py.In vivo, we constructed LLC, R1-LLC and R2-LLC orthotopic transplantation models.Herein, we observed their tumor growth and metastasis.The tumor formation rate and tumor-forming time were recorded for statistic analysis.Results In vitro:LLC, R1-LLC and R2-LLC cells showed no significant difference in proliferation ability ( P>0.05 ) , but significant differ-ences in invasion ability:R2-LLC>R1-LLC>LLC(P<0.05).In vivo:In the orthotopic group, the tumor formation rates of LLC, R1-LLC and R2-LLC cells were 66.67%、80%、93.33%(P <0.05).Conclusions In orthotopic implantation mouse models, R2-LLC cells present higher invasion and metastatic ability than R2-LLC and LLC cells.

Objective To compare gene expression profiles among hepatocellular carcinomas(HCC),cirrhotic liver tissue and normal liver and to analyze their biological information.Methods Total RNA was isolated from hepatocellular carcinomas,cirrhotic liver tissue and normal liver respectively,purified into mRNA by oligotex,and reverse-transcribed to synthetize two kinds of fluorescences(Cy3-dUTP,Cy5-dUTP) labeled cDNA probes.The targets were mixed together and hybridized with the genes on the genechip containing 4096 genes.The following comparisons were performed: hepatocellular carcinomas versus normal liver,cirrhotic liver versus normal liver.Genes that were differentially expressed between these groups were identified based on signal-to-noise ratios by using GenePix Pro3.0 software.Results 141 genes were found with close relation to HCCs,some of these genes were related to cell cycle and signal transduction,such as MCM7,YWHAH,among these,there are 23 genes whose expression tendency consistent with that of cirrhotic liver's.When compared with normal liver,there were 2 genes belong to metallothionein family downregulated in HCCs but upregulated in cirrhotic liver.Conclusion The inactivation of anticancer genes,the abnormality of metabolism related genes and the activation of cell proliferation cycle related genes may have a vital role in HCC.Research into these genes systematically may help to explore new markers of early diagnosisand to guide treatment proposal and to evaluate prognosis better.2007.27(1)
