Objective The purpose of this study was to investigate the preventive effect of flurbiprofen axetil or small-dose ketamine for remifentanil-induced postoperative hyperalgesia. Methods 120 anesthetized patients with ASA ⅠorⅡwere randomly divided into three groups. Group A (40 cases) was given 0.5 mg/kg of ketamine by intravenous injection,and 5μg/(kg.min) vein to maintain,group B (40 cases) was given 100 mg of preoperative flurbiprofen axetil by intravenous injection and group C (40 cases) had no flurbiprofen axetil or ketamine which was served as controls. After the treatment, all groups were given continuous intravenous tramadol controlled analgesia (PCIA) . Results After 1 h, 2 h, 4 h and 8 h, the visual analog scale (VAS) of group C was significantly higher than that of group A and group B ( <0.05);after 24 h, there was no statistically significant difference among the three groups in VAS scores ( > 0.05) . The number of fentanyl analgesia were 25 cases and postoperative 24 h PCIA self-control were (8.6 ±4.2) times, which were more than 7 cases and (3.3 ±2.8) times of group A, and 6 cases and (3.2 ± 2.2) times of group B ( <0.05) . Conclusion The preoperative administration of flurbiprofen axetil or intraoperative continuously administered ketamine is able to prevent the occurrence of remifentanil-induced postoperative hyperalgesia, and it will not affect the patient regained consciousness. The method is safe and reliable,so it is worth promoting and popularizing.

OBJECTIVE: To develop a HPLC method for the determination of the concentration of caffeic acid, chlorogenic acid and 1, 3-dicaffeoylquinic acid in rat urine and to observe the excretion of three compounds in rats. METHODS: Rat urine samples, collected at different intervals after vein injection of Dengzhanxixin injection traditional Chinese medicines, added with protocatechuic aldehyde as internal standard, handled by ethyl acetate, then were measured by HPLC. RESULTS: The recoveries of caffeic acid, chlorogenic acid and 1, 3-dicaffeoylquinic acid were about 95%-98%, 90%-95%, 95%-97%, respectively. The cumulative excretions of caffeic acid, chlorogenic acid and 1, 3-dicaffeoylquinic acid in urine within 60 h were (70.97 ± 7.31)%, (87.62 ± 12.23)% and (9.87 ± 2.63)%. Relative standard deviation(RSD) of intra- and inter-day assay was less than 10%. CONCLUSION: The established method is simple, accurate and specific. It can be successfully used for the analysis of three compounds in rat urine.

OBJECTIVETo develop a life quality scale suitable for idiopathic pulmonary fibrosis (IPF) patients, objectively reflecting its changes.

METHODSAuthors first put forward a theoretical structure model of a scale according to patient-reported outcome (PRO) scale formulation principle by combining basic theories of Chinese medicine (CM). Then authors developed an initial scale on the basis of various life quality scales for respiratory disease patients by using structural decision making. Totally 34 patients with confirmed diagnosis of IPF were tested by questionnaire. Items were screened using expert importance scoring method, factor analysis, correlation coefficient method, Cronbach's alpha coefficient method. IPF patient reported outcomes (IPF PRO, IP) were finally defined.

RESULTSA new IP scale was developed covering three areas and 38 items. Pearson correlation coefficient for correlation analysis of clinical symptom scores in ST-George Respiratory Questionnaire and IP scale was 0.828 (P < 0.01). Pearson correlation coefficient for correlation analysis of activity ability scores was 0.929 (P < 0.01). Pearson correlation coefficient for correlation analysis of total scores was 0.862 (P < 0.01). By reliability of IP scale itself (reliability) analysis, Cronbach's alpha coefficient was 0.713. By using factor analysis method for data analysis, KMO statistics was 0.902.

CONCLUSIONIP scale fully reflected the connotation of IPF patients' quality of life, so it could be used as CM clinical therapeutic effect evaluation tool.

Rice stripe virus (RSV) infects rice and is transmitted in a propagative manner by the small brown planthopper.How RSV enters an insect cell to initiate the infection cycle is poorly understood.Sequence analysis revealed that the RSV NSvc2 protein was similar to the membrane glycoproteins of several members in the family Bunyaviridae and might induce cell membrane fusion.To conveniently study the membrane fusion activity of NSvc2,we constructed cell surface display vectors for expressing Nsvc2 on the insect cell surface as the membrane glycoproteins of the enveloped viruses.Our results showed that NSvc2 was successfully expressed and displayed on the surface of insect Sf9 cells.When induced by low pH,the membrane fusion was not observed in the cells that expressed NSvc2.Additionally,the membrane fusion was also not detected when co-expressing Nsvc2 and the viral capsid protein on insect cell surface.Thus,RSV NSvc2 is probably different from the phlebovirus counterparts,which could suggest different functions.RSV might enter insect cells other than by fusion with plasma or endosome membrane.

Objective To calculate the mean absorbed doses at celluar and subcellular levels for uniformly and non-uniformly distributed Auger electron emitters. Methods The energy deposited in cell or nucleus by Auger electrons was analytically calculated using the polynomial representation of energy loss.S-values were subsequently computed for several target-source combinations.The absorbed dose and dose distribution were calculated for spherically symmetric radionuclide distributions depending linearly and exponentially on the radial position.The dose profile as a function of the source radial coordinate was also evaluated for typical cell sizes.The contributions of photon radiation to absorbed dose in cells were ignored. Results The mean absorbed dose and dose distribution depend largely on the size of target cells,the radiation spectrum and intracellular localization and distribution of radionuclides.The contribution of intranuclear radionuclides to mean absorbed dose was larger than that of extranuclear ones. Conclusion Auger electrons can produce high local energy deposition in cells because of their very low energies and extremely short ranges.Our dose calculation method is simple.The results are reliable and can be used in many fields.

Objective:To evaluate the utilization of antifungal drugs in Nanjing area, and provide clinical reference for the rational use of antifungal drugs. Methods:According to the sales data of antifungal drugs in 34 hospitals in Nanjing area from 2013 to 2015, the utilization of antifungal drugs was analyzed in respects of consumption sum, DDDs and DDC. Results:The consumption sum and use of antifungal drugs increased year by year. The maximum amount of consumption sum growth rate was 41. 13%. Triazole drugs oc-cupied the top of consumption sum during the past three years, and the sales amount accounted for more than 60% of all. In term of consumption sum, voriconazole, fluconazole, itraconazole and caspofungin ranked top 4 of antifungal drugs. Clotrimazole topical prepa-rations and oral itraconazole ranked top 2 of DDDs, and caspofungin, micafungin and voriconazole ranked top 3 of DDC. Conclusion:The clinical application of antifungal drugs continues to increase during 2013 and 2015. Invasive fungal infection is a lethal factor at high risk. Choosing reasonable, effective, safe and economic of antifungal drugs is the first principle in clinical treatment.
