Within a framework of Halliday＇s SFL （Systemic Functional linguistics）, this paper takes a functional approach to the analysis of the fairy tale--＂The little Match-Seller＂（Andersen, 1846）. The analysis is carried out in three respects： genre, register and language. Genre analysis indicates that the schematic structure of the fairy tale is very much in line with the one mentioned by Hasan. Register analysis shows that the material process is the most dominant one; the Finite in the clauses is predominantly in past tenses, and most of the Themes in the text are unmarked ones. Language analysis reveals that the lexical density in the fairy tale is relatively low. The findings in this paper can help deepen people＇s understanding of the textual features of English fairy tales.

Some H5 viruses isolated in poultry or wild birds between 2020 and 2021 were found to be antigenically different from the vaccine strains(H5-Re11 and H5-Re12) used in China. In this study, we generated three new recombinant vaccine seed viruses by using reverse genetics and used them for vaccine production. The vaccine strain H5-Re13 contains the hemagglutinin(HA) and neuraminidase(NA) genes of an H5 N6 virus that bears the clade 2.***.4.4 h HA gene, H5-Re14 contains the HA and NA genes of an H5 N8 virus that bears the clade 2.***.4.4 b HA gene, and H7-Re4 contains the HA and NA genes of H7 N9 virus detected in 2021. We evaluated the protective efficacy of the novel H5/H7 trivalent inactivated vaccine in chickens, ducks, and geese. The inactivated vaccine was immunogenic and induced substantial antibody responses in the birds tested. Three weeks after vaccination, chickens were challenged with five different viruses detected in 2020 and 2021: three viruses(an H5 N1 virus, an H5 N6 virus, and an H5 N8 virus) bearing the clade 2.***.4.4 b HA gene, an H5 N6 virus bearing the clade 2.***.4.4 h HA gene, and an H7 N9 virus. All of the control birds shed high titers of virus and died within 4 days post-challenge, whereas the vaccinated chickens were completely protected from these viruses. Similar protective efficacy against H5 viruses bearing the clade 2.***.4.4 h or 2.***.4.4 b HA gene was observed in ducks and geese. Our study indicates that the newly updated H5/H7 vaccine can provide solid protection against the H5 and H7 N9 viruses that are currently circulating in nature.

One new chiral zeolitic rho-type metal-organic framework [Cd（L-ala）2]n（1） has been successfully synthesized based on L-alanine chiral ligand, which demonstrates the feasibility of fabricating MOF that integrates the 4-connected zeotype topology by the employment of L-alanine. To the best of knowledge, it’s the first report that metal-organic framework based on amino acid features the chiral zeolitic rho-type structure. Compound 1 was characterized by X-ray powder diffraction, elemental analysis and single-crystal X-ray diffraction. Crystal data: C6 H9 CdN2 O4, Mr = 285.55, cubic system, space group I432, a = 24.0795（6）, V = 13961.9（10） ?3, Z = 48, Dc = 1.630 Mg/m3, F（000） = 6672, μ（Mo Kα） = 1.865 mm-1, S = 1.058, R = 0.0271 and wR = 0.0312 for 1870 observed reflections with I > 2σ（I）. The circular dichroism（CD） property of compound 1 was also investigated.

Background Early intensive insulin therapies in newly diagnosed type 2 diabetic patients may improve β-cell function and yield prolonged glycemic remissions. This study was performed to evaluate the relationship between the glycemic remission and 13-cell function and assess the variables predictive of long-term near-normoglycemic remission. Methods Eighty-four newly diagnosed type 2 diabetic patients were treated with 2-week continuous subcutaneous insulin infusion （CSII） and followed up longitudinally. Intravenous glucose tolerance tests （IVGTTs） were performed, and blood glucose, hemoglobin Alc （HbAlc） and insulin were measured at baseline, after CSII and at 2-year visit. The patients who maintained glycemic control for two years were defined as the remission group and those who relapsed before the 2-year visit were the non-remission group. Results The duration to be diagnosed of the patients （from the time that patients began to have diabetic symptoms until diagnosis） in the remission group was shorter than that in the non-remission group （1.00 month vs 4.38 months, P=0.040）. The increase of the acute insulin response （AIR） was maintained after 2 years in the remission group compared with AIR measured immediately after intervention （413.05 pmol·L^-1·min^-1 vs 408.99 pmol·L^-1·min^-1, P=0.820）. While AIR in the non-remission group significantly declined （74.71 pmol·L^-1·min^-1 vs 335.64 pmol·L^-1·min^-1, P=0.030）. Cox model showed that a shorter duration to be diagnosed positively affected the duration of near-nomoglycemic remission with an odds ratio （OR） 1.019, P=0.038, while fasting plasma glucose （FPG） and post-breakfast plasma glucose （PPG） after CSII were the risk factors （OR 1.397, P=0.024 and OR 1.187, P=0.035, respectively）. Conclusion The near-normoglycemic remission is closely associated with long-term maintenance of β-cell function and occurs more commonly in patients with shorter duration to be diagnosed and better glycemic control during CSII.

Background Cumulative evidence demonstrates that primary percutaneous coronary intervention（PCI）is a mperfusion strategy for ST-elevation myocardial Infarction（STEMI）.This study was undertaken to evaluate the pre-hospital care-seeking pathway and subsequent care quality in patients with STEMI in the Beijing health care system,which offers patients a choice between seeking care in a small community hospital（SH group）or a large hospital（LH group）.Methods Between January 1 and December 31,2006, a cross-sectional and multicenter survey was conducted in 11 hospitals qualified as tertiary centers in Beijing and included consecutive patients with STEMI admitted within 24 hours after onset of *** Among the 566 patients interviewed,28.3%first arnved at a small community hospitaI and were transferred to large hospitals with the ability to perform primary *** median total pre-hospital delay in the SH group（n=160）was significantly longer than in the LH group（n=406）（225 vs.120 minutes,P〈0.001）.Multivariate analysis showed that interpreting symptoms to non-cardiac origin（OR,1.996;95%CI： 1.264-3.155）,absence of history of myocardial infarction（OR,1.595;95%CI：1.086-3.347）,non-health insuranca coverage（OR,1.931;95%Cl：1.079-3.012）and absence of sense of impending doom （OR,4.367;95%CI：1.279-1 4.925） were independent predictors for choosing small *** adjusting for demographics and medical history,patients in the SH group were 1.698 times（95% CI： 1.1 82-3.661） less likely to receive primary PCI compared with those in the LH group. Conclusions Above one fourth of the STEMI patients in Beijing experienced inter-hospital *** including symptoms interpretation,symptoms,history of myocardial infarcUon,and insurance coverage were associated with the patients＇pre-hospital care-seeking *** patients who were transferred had longer pre-hospital delays and were less Iikely to receive primary PCI.
