Objective:To investigate the value of nasal provocation test（NPT） in evaluating the efficacy of allergen immunotherapy（AIT） in patients with dust mite induced allergic rhinitis（AR）. Methods:A total of 83 patients with dust mite induced AR with/without asthma were included. Symptom score（SS）, daily medication score（DMS）, combined symptom and medication score（CSMS）, rhinoconjunctivitis quality of life questionnaire（RQLQ）, NPT and skin prick test（SPT） were assessed before and after 1 year AIT. Results:There were statistical differences in SS（P<0.000 1）, DMS（P<0.000 1）, CSMS（P<0.000 1）, and RQLQ（P<0.000 1） after 1 year of AIT compared with pre-treatment. The effective rate of CSMS was 73.49%, and the effective rate of NPT was 42.17%. CSMS was consistent with NPT in efficacy assessment（Kappa=0.437, P<0.001）; while in 54 patients with pre-treatment NPT concentrations other than the original concentration, CMSM and NPT showed better consistence（Kappa=0.895, P<0.001）. Among the 48 patients with ineffective NPT assessment in the first year, 25 patients completed the second-year follow-up, and 12 patients（48.00%） showed effective in NPT. However, 10 out of 12 patients（83.33%） with NPT concentration other than original solution pre-treatment showed effective NPT at the second year. Conclusion:NPT can be used as one of the indicators for efficacy evaluation for dust mite induced AR patients, especially for patients with positive NPT induced at lower concentrations before treatment.

Objective:To investigate the value of aspirin challenge tests in the diagnosis of non-steroidal anti-inflammatory drugs-exacerbated respiratory disease (NERD).Methods:Fifty patients (22 males and 28 females; aged 16-61 years) who were diagnosed with chronic rhinosinusitis with nasal polyps (CRSwNP) with/without asthma, and underwent NERD standardized diagnosis in the Allergy Centre of West China Hospital, Sichuan University from December 2021 to November 2022 were included in the study. The first step was asking about the history of exacerbation respiratory symptoms after intake of any non-steroidal anti-inflammatory drug, including aspirin; the second step was performing intranasal aspirin challenge (IAC); and the third step was performing oral aspirin challenge (OAC). The diagnosis of NERD was made if any of the above steps was positive, and the subsequent steps were not performed, otherwise the diagnosis was made to OAC. If OAC was negative, the diagnosis was non-NERD. All patients completed the sino-nasal outcome test 22 (SNOT 22) score, Lund-Kennedy score by nasal endoscopic, allergen skin prick test, blood routine and serum total IgE test. SPSS version 20.0 was used for statistical analysis.Results:The diagnosis of NRED was confirmed in 27 patients (27/50, 54%). Seven (7/50, 14%) of them were diagnosed by clinical history and 20 (20/50, 40%) were diagnosed by aspirin challenge tests, of which 17 (17/20, 85%) were positive to IAC and 3 (3/20, 15%) to OAC. Of the 43 patients who underwent IAC testing, only 2 (2/43, 5%) developed asthma attacks during challenge. Comparing the clinical characteristics of patients in NERD and non-NERD group, there were significant differences between the two groups in gender ( P=0.001), hyposmia ( P=0.003), history of repeated CRSwNP surgeries ( P=0.028), comorbid asthma ( P=0.013), SNOT-22 score ( P=0.004) and the percentage of peripheral blood eosinophil ( P=0.043). Conclusions:Patients may be underdiagnosed if the diagnosis of NERD is made only by medical history, and it is necessary to carry out aspirin challenge tests. IAC is an important means to diagnose NERD with high accuracy and good safety. However, If IAC is negative, further OAC is required.

Conclusion Traditional Chinese medicine Angong Niuhuangwan can be used to help treat patients with pulmonary encephalopathy, it can help them improve their respiratory function, avoid mechanical ventilation, significantly elevate their cure rate and ameliorate their sufferings.

Objective: To study the antibacterial activity in vitro of Xiyanping injection combined with cefoxitin, cefuroxime, ceftriaxone, cefmenoxime, amikacin, levofloxacin and meropenem against staphylococcus aureus, escherichia coli, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter bauman.Methods: Minimum inhibitory concentration (MIC) of the 7 kinds of antimicrobial agents used individually or combined with Xiyanping injection on germs were determined respectively on 96 plates by using the agar dilution method and the checkerboard method.Fractional inhibitory concentration index (FICI) was calculated to evaluate the antibacterial activity of Xiyanping injection combined with the 7 kinds of antimicrobial agents in vitro.Results: MIC of Xiyanping injection combined with cefoxitin was the same as that of cefoxitin used individually on escherichia coli.MIC of levofloxacin combined with Xiyanping injection showed no difference with that of levofloxacin used individually on klebsiella pneumoniae.Besides, Xiyanping injection could increase the MIC of the other antimicrobial agents on germs.Conclusion: Xiyanping injection combined with antimicrobial agents on staphylococcus aureus, escherichia coli, klebsiella pneumoniae shows antagonistic and irrelevant relationship.

Objective:To investigate the expression and clinical significance of long non-coding RNA (LncRNA) CRNDE in cer-vical cancer. Methods:Specimens of cervical cancer tissues and matched non-tumor para-neoplastic tissues were collected from 87 pa-tients who underwent surgery in the Kaiping Central Hospital, China. Quantitative real-time PCR was used to examine the expression of LncRNA CRNDE, and its correlation with clinicopathological features was analyzed. Results:LncRNA CRNDE expression was sig-nificantly up-regulated in cervical cancer tissues than in adjacent non-tumor tissues (P<0.05). Increased LncRNA CRNDE expression was significantly correlated with FIGO stage, lymph node metastasis, and depth of cervical invasion (P<0.05). Moreover, a higher ex-pression of LncRNA CRNDE demonstrated significantly poorer overall survival in cervical cancer patients than in those with lower Ln-cRNA CRNDE expression (P<0.05). Multivariate analyses suggested that LncRNA CRNDE expression served as an independent pre-dictor for overall survival. Conclusion:Our findings posit that LncRNA CRNDE may be a potential prognostic marker and therapeutic target for cervical cancer.

To explore the stability of Shenkang injection respectively in five different solutions to choose the best com-patibility program and improve the rational drug use. Methods:The pH value, insoluble particles and the content of protocatechuic al-dehyde in Shenkang injection were determined after mixed with five solutions. Results:In the 6-hour mixing, the change order of proto-catechuic aldehyde content was 0. 9% sodium chloride injection> 5% fructose injection> 10% invert sugar injection > 5% dextrose injection> 10% glucose injection, especially in 0. 9% sodium chloride injection, the content was decreased by 20%. The number of insoluble particles was increased after the 2-hour mixing except in 10% invert sugar injection solution, and the increase in the four so-lutions was beyond the requirement in the 2010 edition of Chinese Pharmacopoeia, and the number of insoluble particles in 0. 9% sodi-um chloride injection was the highest with the fastest change. During the experimental process, the pH value was stable. Conclusion:The five solutions show influence on stability of Shenkang injection in varying degrees. Shenkang injection in 0. 9% sodium chloride in-jection is the least stable, which should be used with caution in clinics, while invert sugar injection and glucose injection can be the best choice for Shenkang injection and the mixed solution should be used up in 2h.
