Objective To investigate the need and utilization for health services in patients with allergic rhinitis in Qingdao area.Methods An investigation was conducted by the method of combining multi-stage sampling and cluster sampling.SPSS 13.0 software was used to analyse the data.Results Among Two thousand and four hundred questionnaires,two thousand and fifty-two questionnaires were available.The effective rate was 85.5％.The total two-week prevalence in male was 6.5％,while that in female was 6.2％.There was no significant difference between male and female( x2 =0.103,P ＞ 0.05 ).The total ratio of those who visited doctors was 1.7％.The ratio of those who visited doctors in the first two weeks was 26.7％ ( 35/131 ).49.0％ of non-users of health service thought it was unnecessary to consult a doctor because of mild symptoms.In the investigation about the allergic rhinitis,60.2％ patients (1235/2052) confessed that they heard of allergic rhinitis,30.0％ patients (616/2052) thought of allergic rhinitis was common cold.Conclusions The number of patients treated for allergic rhinitis was less than its prevalence.The primary reason for low attendance was that the majority of patients with mild symptoms thought it was no need to see a doctor.In order to improve the residents' health services utilization,medical education for allergic rhinitis is necessary.

AIM: To identify the structure of the acid-catalyzed product of strictosamide and explore the reaction mechanism. METHODS: The acid-catalyzed reaction process of strictosamide was monitored by HPLC, and a macroporous resin was used to purify the reaction solution. The structure of the product was confirmed by MS, NMR, and ROESY spectra. RESULTS: The acid-catalyzed transformation yield from strictosamide to vincoside lactam was 52%. CONCLUSION The reaction mechanism of the transformation from strictosamide to vincoside lactam may be related to the stability of the three-dimensional configuration of the compound. These results offer a new way to obtain vincoside lactam from the widely distributed indole alkaloid strictosamide by acid-catalysis.

Objective:To investigate the topological alterations in brain functional networks following comprehensive treatment including brain-computer interface (BCI) training in subacute stroke subjects. Methods:From January, 2018 to June, 2019, 14 subacute stroke patients with moderate to severe upper limbs paralysis accepted routine physical therapy, occupational therapy and BCI training based on motor imagery, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Action Research Arm Test (ARAT) and Wolf Motor Function Test (WMFT) before and after treatment, while the functional connectivity (FC) was investigated with resting state functional magnetic resonance imaging. Results:The scores of FMA-UE, ARAT and WMFT increased after treatment (|t| > 5.298, Z = -3.297, P < 0.01). The FC also increased across the whole brain, including temporal, parietal, occipital lobes and subcortical regions. The FC between left piriform cortex of parietal lobule (BA5L) and right medial surface of temporal lobe (BA48R), as well as those between left precentral gyrus (BA4L) and right anterior transverse temporal gyrus (BA41R) (r > 0.416, P < 0.05). Conclusion:Comprehensive rehabilitation including BCI training may promote recovery of motor function and activities of FC in brain in subacute stroke patients.
