To explore new agents of quinolone derivatives with high antibacterial activity, 7-(4-alkoxyimino-3-methyl-3-methylaminopiperidin-1-yl)quinolones were designed and synthesized, and their activity against gram-positive and gram-negative strains was tested in vitro. Sixteen target compounds were obtained. Their structures were established by 1H NMR, HRMS and X-ray crystallographic analysis. Compounds 14k and 14m-14o show good antibacterial activity against the tested five gram-positive strains and five gram-negative strains (MIC: 0.25-16 micromg x mL(-1)), of which the most active compound 14o is 8-fold more potent than levofloxacin against S. pneumoniae (MIC: 4 microg x mL(-1)), and comparable to levofloxacin against S. aureus, S. epidermidis, E. faecalis and E. coli (MIC: 0.25-1 microg x mL(-1)), but generally less potent than gemifloxacin.

Objective To observe the influence of emergency PCI in different time windows to cardiac scar and cardiac function after myocardial infarction. Methods One hundred and twenty-seven patients with acute myocardial infarction, who were treated in different time windows by emergency PCI, were enrolled into this study. The cases were divided into two groups according to the time when they took PCI after onset;group 3 hPCI included 66 patients had PCI at 3 h after onset and group 6 hPCI included 61 patients had PCI at 6 h. At 4th, 8th and 12th weeks, the fragmented QRS (fQRS) were observed by twelve synchronization cardiogram; ventricle wall movement strain rate were determined by cardiac speckle tracking imaging;left ventricular ejection fraction (LVEF)were measured by cardiac ultrasound to evaluate cardiac events and cardiac function after myocardial infarction. Results At 4th,8th and 12th weeks,the fQRS positive leads were significantly more in 6 hPCI group than 3 hPCI group ( P < 0. 05 respectively ) . The ventricle wall movements strain rate and LVEF improved significantly in 3 hPCI group compared with 6 hPCI group (P < 0. 05 ). Conclusions The earlier emergency PCI treatment was applied and the earlier the"criminal"blood vessels were opened ,the more ischemic myocardial cells were restored. Combination use of fQRS、 STI and LVEF examination could improve the diagnosis of cardiac scar formation and direct protective therapy.

NAS preparation, a kind of Chinese herbal medicine found by the Yunnan Eco-agricultural Research Institute, has potential antiviral activity. In this paper, the inhibiting effect of NAS preparation on H9N2 subtype Avian influenza virus (AIV) was investigated in vivo. Chickens infected with H9N2 virus were treated with NAS preparation for 4 days. The virus was then detected by hemoagglutination (HA) test and reverse transcription polymerase chain reaction (RT-PCR). The results showed that no H9N2 virus could be detected at the 7th day when the chickens were treated with 0.2g/kg/d or 0.1g/kg/d of NAS preparation. However the virus could be detected in other chickens without NAS preparation treatment. This result suggested that NAS preparation may be a potential drug candidate to control infection of H9N2 subtype AIV in chickens.

AIM: To probe into the anti-epilepsy action of artificial Calculus Bovis,by observing its effect on the behavioral of the experimental epileptic rats,neuron loss in the hippocampus and hilus,and GAD positive cell alteration in the hippocampus.METHODS: SD rats were divided into three groups: group A(artificial Calculus Bovis treatment group);group B(acute epilepsy group) and group C(control group).A model of acute epilepsy rats was established by PTZ.The rat's behavioral alteration was observed by the Racine' scale.The neurons in the hippocampus and hilus were calculated by Nissl staining.The GAD positive cells were observed by immunohistochemical staining.RESULTS: The latency of the first seizure in group A was longer than that in group B,while the seizure times in group A was less than that in group B.Besides,in group A,both the neuron loss amount in the hippocampus and hilus and the GAD positive cell loss amount in the hippocampus were less than those in group B.CONCLUSION: The artificial Calculus Bovis prolonged the latency of the first seizure time,decreased the frequency of seizure,and prevented the neuron loss and protected the GAD positive cells.

Objective:To design a multi-epitope antigen of norovirus(NoV)based on bioinformatics technology and to pre-pare and characterize it.Methods:Bioinformatics methods were used to construct and analyze the NoV multi-epitope antigen NoV-ZH.Recombinant proteins were prepared and characterized by prokaryotic expression system,and monoclonal antibodies were prepared by animal immunization and hybridoma technology,and initially applied in colloidal gold platform.Results:The designed multi-epitope antigen had a large proportion of random curls in the secondary structure,with theoretical molecular mass and isoelectric point(PI)of 13.1 ku and 7.16,which were stable and hydrophilic.It had good immunogenicity and could activate humoral and cellular immune re-sponses.The proteins prepared by ligating pET-28a(+)and pET-32a vectors with antigenic sequences were expressed as inclusion body proteins and soluble proteins,respectively.A pair of paired antibodies was obtained by animal immunization and hybridoma tech-nique,and applied to colloidal gold test strips with a sensitivity of 0.5 ng/ml,and the test strips could specifically bind two genotypes of NoV recombinant capsid proteins.Conclusion:The successful preparation and characterization of multi-epitope antigen of norovirus provides a reference for the subsequent exploration of NoV universal detection targets and the development of diagnostic raw materials.

Objective:To explore the effect of exercise therapy on the exercise capacity and quality of life of maintenance hemodialysis patients.Methods:A total of 90 patients who underwent regular dialysis in Henan Provincial People′s Hospital, People′s Hospital of Zhengzhou University from April to December, 2020 were selected as the research objects by convienient sampling method. They were divided into experimental group and control group by random number table method, with 45 cases in each group. The control group was given routine nursing, and the experimental group took exercise therapy on the basis of routine nursing. The intervention lasted for 12 weeks. The changes in the exercise capacity and quality of life of the two groups before and after the intervention were observed.Results:Finally, 43 patients were included in the control group and 41 patients in the experimental group. There was no significant difference in the exercise capacity and quality of life before the intervention between the two groups( P>0.05). After the intervention, the maximum oxygen uptake, anaerobic threshold, 6MWT distance were (15.22 ± 3.08) ml·kg -1·min -1, (620.70 ± 53.56) ml·kg -1·min -1, (475.36 ± 50.51) m in the experimental group, and (12.22 ± 2.46) ml·kg -1·min -1, (590.18 ± 52.07) ml·kg -1·min -1, (444.50 ± 46.09) m in the control group, the differences were statistically significant between the two groups( t=3.32, 2.68, 296, all P<0.05). After the intervention, the scores of physiological function, physiological intelligence, physical pain, overall health, vitality, social function, emotional function and mental health dimensions of the quality of life were (84.32 ± 18.53), (84.61 ± 25.80), (76.40 ± 18.15), (59.02 ± 15.38), (52.22 ± 13.68), (69.56 ± 17.29), (94.24 ± 29.47), (73.44 ± 12.86) points in the experimental group, and (76.25 ± 17.35) (66.37 ± 27.63), (65.68 ± 17.54), (47.26 ± 15.45), (44.86 ± 13.14), (61.82 ± 16.51), (76.30 ± 26.14), (64.17 ± 13.36) points in the control group, the differences were statistically significant between the two groups( t values were 2.08-3.54, all P<0.05). Conclusions:Exercise therapy during dialysis can enhance exercise capacity and improve quality of life in maintenance hemodialysis patients.
