Objective To evaluate the clinical effectiveness and safety of compound loratadine capsule in the treatment of allergic rhinitis. Methods A multi-center randomized single blind controlled trial (by using a random number table generated random sequence and the sequence was concealed by sealed envelopes) was designed. Two hundred and forty outpatients with allergic rhinitis who met the inclusion and exclusion criteria were randomized to the treatment group (n=120 with compound loratadine capsule, 1 capsule q 24 h) or the control group (n=120 with loratadine tablet, 1 tablet q 12 h). All patients were given standard therapy. Results ① At the end of the treatment, in the compound loratadine group, 101 patients completed the study, and 19 patients withdrew. In the loratadine group, 103 patients completed the study, 17 patients withdrew. According to intention-to-treat analysis (ITT), the improvement rates of the treatment and control groups were 89.17% (107/120) and 88.33% (106/120) respectively. No significant difference was seen between the two groups (rank sum test, u=-1.8348, P＞0.05). According to per-protocol analysis (PP), the improvement rates of the treatment and control groups were 96.04% (97/101) and 91.26% (94/103) respectively. No significant difference was seen between the two groups (rank sum test, u=-1.625 7, P＞0.05). ② Adverse events were slight to moderate.The adverse event rates were 22.5% (27/120) and 21.67% (26/120) in the treatment and control groups respectively. No significant difference was seen between the two groups ( χ2 test, P＞0.05). Conclusion Compound loratadine capsule is effective and safe for allergic rhinitis.

ObjectiveTo investigate the common inhalant allergens causing allergic rhinitis in underage patients, and provide references for clinical prevention of allergic rhinitis. MethodsUnderage patients with allergic rhinitis admitted to our hospital between January 2010 and June 2013 were screened and skin prick test (SPT) was applied to investigate the response intensity to 22 kinds of common inhalant allergens and analyze the correlation of the positive rates and grades of allergens with age and sex. ResultsA total of 402 patients were included, and 77.6% (312/402) of them reported positive reaction of SPT; and the top five allergens were dust mites (242/402, 60.2%), house dust (235/402, 58.5%), housefly (142/402, 35.3%), spring pollen Ⅲ (133/402, 33.1%) and mulberry silk (121/402, 30.1%), respectively. Compared with patients whose age was younger than 5 years, both the positive rates and grades of SPT were significantly higher in patients above 5 years old. Additionally, the higher positive rates and grades of SPT were also observed much more in male patients than female patients. ConclusionThe most common inhalant allergens causing allergic rhinitis in underage patients are dust mites and house dust. And the SPT response intensity of inhalant allergens can be affected by age and gender.

Methods A total of 42 patients with OSAHS complicated with allergic rhinitis between January 2010 and May 2010 were chosen. All of the patients were treated by low-temperature plasma radio frequency nerve block, concha nasalis inferior ablation and other operations such as nasal septal construction. The nerve terminals of sphenopalatine nerve and anterior ethmoid nerve were blocked by ablation. Epworth sleepiness scale (ESS) and visual analogue scale (VAS) were used to estimate the curative effects. Results The results of ESS and VAS were consistent with gaussian distribution. There were statistical significant difference between the scores of pre-and post-operation (Plt;0.05). Conclusion The low-temperature plasma radio frequency treatment for OSAHS complicated with allergic rhinitis is easy，safe and efficient.
ObjectiveTo observe the effect of Budesonide formoterol inhalant on teenager patients with allergic rhinitis accompanied with asthma. MethodsForty-five teenager patients with allergic rhinitis accompanied with asthma treated between January 2012 and December 2013 were randomly divided into general treatment group, budesonide group and budesonide formoterol group, with 15 patients in each. Another 15 subjects undergoing physical examination were designated as the control group. Besides routine treatment, the budesonide group was also treated with budesonide inhalation at 100-200 μg twice a day, and the budesonide formoterol group was also treated with budesonide formoterol inhalation at 160 μg and 4.5 μg twice a day. The course of treatment lasted for four weeks. The patients were followed up for four weeks after the use of medicine halted. After treatment, exhaled nitric oxide (NO) examination were performed. ResultsThe amount of NO in the exhaled gas in all the three treatment groups were significantly different from the control group (P<0.05), and it was also significantly different between the Budesonide group and the budesonide formoterol group (P<0.05). ConclusionBudesonide formoterol inhalant has a good effect on teenager patients with allergic rhinitis accompanied with asthma in terms of improving exhaled NO.
Objective To review the research progress of the feasibility of a new treatment method for atrophic rhinitis (ATR) based on tissue engineering technology (seed cells, scaffold materials, and growth factors), and provide new ideas for the treatment of ATR. MethodsThe literature related to ATR was extensively reviewed. Focusing on the three aspects of seed cells, scaffold materials, and growth factors, the recent research progress of ATR treatment was reviewed, and the future directions of tissue engineering technology to treat ATR were proposed. Results The pathogenesis and etiology of ATR are still unclear, and the effectiveness of the current treatments are still unsatisfactory. The construction of a cell-scaffold complex with sustained and controlled release of exogenous cytokines is expected to reverse the pathological changes of ATR, promoting the regeneration of normal nasal mucosa and reconstructing the atrophic turbinate. In recent years, the research progress of exosomes, three-dimensional printing, and organoids will promote the development of tissue engineering technology for ATR. ConclusionTissue engineering technology can provide a new treatment method for ATR.
Objective This review compared clinical effectiveness, cardiac safety and economics of astemizole, loratadine, cetirizine and terfenadine to provide evidence for adjustment of Essential Drug List in China. Search strategy We searched Medline, Cochrane Library, Embase and Chinese Biomedical Database. Fourteen databases for drug safety and pharmaceutical economics were additionally searched. Selection Criteria Randomized controlled trials and systematic reviews, published in English and Chinese and comparing two or more of these four antihistamines for allergic rhinitis and urticaria were included for study of effectiveness. Non-randomized clinical trials were additionally included for economic evaluation. Cardiac safety studies of antihistamines for allergic diseases of any type were included. Quality Appraisal Jadad scale was primarily applied to randomized controlled trials. Allocation concealment and intention-to-treat analysis were also appraised. The QUOROM statement was applied to systematic reviews and meta-analysis. Data extraction and analyses For the study of effectiveness, composite data were primarily extracted and analyzed by fixed effect model. Sensitivity analysis was done to explore the heterogeneity. For the study of cardiac safety, cases of adverse drug reactions and death were summarized. Difference of occurrence rate in sex and age were analyzed if possible.Electrocardiography and clinical symptoms were summarized. Results No studies on economic evaluation were identified. 27 and 6 randomized controlled trials, including 3 227 participants, for allergic rhinitis and urticaria were identified. Cetirizine was superior to loratadine (n=709) in symptom score and onset of action, superior to terfenadine (n=645) in Quality of Life and superior to astemizole (n=498) in patient satisfaction and onset of action. 73 h-ADR cases were identified in astemizole, 27 cases in terfenadine, 1 case in loratadine and none in cetirizine. No deaths were identified. Combination of terfenadine plus grapefruit juice (n=l8), itraconazole (n=6), nefazodone (n=67), and loratadine administration concomitant with cemitidine (n=30) significantly prolonged QTc interval. Conclusions Cetirizine was superior to other three antihistamines in terms of clinical effectiveness and drug safety. Astemizole and terfenadine could cause significantly more cardiac-related adverse reactions than cetirizine and loratadine.
